CFR

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

This action proposes to update the Environmental Protection Agency's (EPA) existing gasoline, diesel, and other fuels programs to improve overall compliance assurance and maintain environmental performance, while reducing compliance costs for industry and EPA. EPA is proposing to streamline its existing fuel quality regulations by removing expired provisions, eliminating redundant compliance provisions (e.g., duplicative registration requirements that are required by every EPA fuels program), removing unnecessary and out-of-date requirements, and replacing them with a single set of provisions and definitions that will apply across all gasoline, diesel, and other fuels programs that EPA currently regulates. This action does not propose to change the stringency of the existing fuel quality standards.

DATES:

Comments. Comments must be received on or before June 29, 2020. Under the Paperwork Reduction Act (PRA), comments on the information collection provisions are best assured of consideration if the Office of Management and Budget (OMB) receives a copy of your comments on or before June 15, 2020.

A. Overview of Fuels Regulatory Streamlining

1. Why EPA Is Taking This Action

As part of our continual effort to update our regulations to ensure that fuel quality standards established under the Clean Air Act (CAA) continue to be met in-use, while minimizing the burden associated with doing so, we are proposing to streamline and modernize our existing 40 CFR part 80 (“part 80”) fuel quality regulations by transferring them into a new proposed set of regulations in 40 CFR part 1090 (“part 1090”). In this action, we are taking a wholistic look at the existing part 80 regulations in an attempt to consolidate the many different and overlapping regulations into the proposed part 1090 regulations that will also better reflect how fuels, fuel additives, and regulated blendstocks are produced, distributed, and sold in today's marketplace.

2. What Is and Is Not Covered in This Action

This action focuses primarily on streamlining and consolidating our existing gasoline and diesel fuel programs that currently reside in part 80.[1] To accomplish this, we are proposing to remove expired provisions and consolidate the remaining provisions from multiple fuel quality programs into a single set of requirements. This action covers almost all fuel programs and related provisions currently in part 80. These programs include, but are not limited to, the reformulated gasoline (RFG) program, the anti-dumping program, the diesel sulfur program, the gasoline benzene program, the gasoline sulfur programs, the E15 misfueling mitigation program, and the national fuel detergent program. This proposed streamlining effort aims to combine these separate, now fully-implemented programs, all of which affect the same regulated parties, into a single, national fuel quality program.

While this action proposes changes to many aspects of our fuel quality programs, there are several areas of the existing part 80 regulations that would remain unchanged. Most importantly, this action does not change the stringency of the existing fuel quality standards. We are simply proposing to streamline and consolidate the existing part 80 fuel quality programs into a single streamlined fuel quality program that would make compliance with the existing fuel quality standards under part 80 more straightforward, and as a result potentially improve fuel quality through increased compliance with our fuel quality standards. This action proposes to transfer the part 80 fuel quality standards mostly unchanged to part 1090, though in some cases we are proposing to modify the form of the standards to translate them into a format more conducive to streamlining the regulations and ensuring in-use compliance.

We recognize that while we are not proposing changes to the standards, in some cases, the proposed consolidation of certain provisions may slightly, indirectly affect in-use fuel quality. For example, proposed changes to how parties record and report test results that fall below the test method's lower limits of detection might cause parties to have to report slightly higher sulfur and benzene levels in gasoline, effectively improving in-use fuel quality by slightly decreasing the sulfur national annual average. On the other hand, the proposal to make it easier for fuel manufacturers of conventional gasoline (CG) to account for oxygenates (e.g., ethanol) added downstream of the manufacturing facility, thereby allowing for a slightly lower reported level of gasoline benzene and sulfur levels, might be perceived as slightly decreasing in-use fuel quality. There are many such minor impacts of changes in part 1090 and we believe that on balance the proposed program would maintain the same overall level of fuel quality as the current part 80 standards. Throughout this preamble, we have tried to identify such cases and we discuss the cumulative costs and benefits of these changes in more detail in Section XIV.

We are also proposing some slight modifications to the Renewable Fuel Standard (RFS) program in subpart M of part 80, primarily for administrative purposes that follow from the proposed changes to our other fuel programs. These subpart M regulations are mostly unique to the RFS program, and therefore do not need to be consolidated with the other part 80 fuel standard regulations. One of the goals of this action is to help ensure consistency in how parties comply with our regulatory requirements and report information to EPA. Since the RFS program uses similar, if not the same, reporting systems and compliance mechanisms for parties to demonstrate compliance, we are proposing changes to help ensure that this consistency is maintained or enhanced as a result of this action. We will treat public comments received suggesting substantive changes to the RFS program as outside the scope of this rulemaking.

Finally, this action does not propose to remove any statutory requirement for fuels specified by the CAA. For example, this action does not propose to remove limits on lead levels in gasoline under CAA section 211(n), remove the requirement that all gasoline be additized with detergents under CAA section 211(l), or cetane index limits for diesel fuel under CAA section 211(g) and (i). While this action does update some of the provisions put in place to implement many provisions of the CAA, and in some cases substantially streamline the implementing regulations (e.g., for the gasoline detergents program), we are not proposing to eliminate any requirement under the CAA for fuels and parties that make, distribute, and sell such fuels.

The majority of this action's proposed changes relative to part 80 focus on consolidating and streamlining compliance provisions currently in part 80, not on adding new compliance requirements for regulated parties. This action also does not propose to impose new standards on fuels. As such, this action is mostly a compilation of numerous, relatively minor proposed changes to the existing provisions under part 80. Many of these proposed changes may appear disconnected from one another, as they are addressing a specific technical area that needs consolidation, streamlining, and/or updating. Together, however, these proposed changes will lead to a more effective, efficient EPA fuels program.

3. Program Design

The new part 1090 is designed to reduce compliance burdens for both industry and EPA, potentially lower fuel costs for consumers, and maintain fuel quality. To accomplish these goals, we have identified three key elements that are included in part 1090:

  • A simplification of the RFG summer VOC standards.
  • A consolidation of the regulatory requirements across the part 80 fuel quality programs.
  • Improving oversight through the leveraging of third parties to ensure in-use fuel quality.

First, we are proposing to simplify the RFG standards by translating the current summer RFG VOC standard into an RVP per-gallon cap of 7.4 psi. This proposed change would allow us to remove the use of the Complex Model [2] as a requirement to certify batches of gasoline and remove all the provisions associated with demonstrating compliance on average. This proposed change would also allow for us to minimize the restrictions on the commingling of RFG and CG, allowing for a more fungible and efficient gasoline distribution system.

The main remaining difference between RFG and CG is that in the summer, RFG's volatility is functionally controlled through a summer VOC performance standard determined with the Complex Model instead of through the RVP per-gallon maximum standards established for CG under CAA section 211(h). EPA has previously aligned the treatment RFG and CG for NOX performance through the Tier 2 gasoline sulfur program and toxics performance through the national gasoline benzene program.[3] This action would align treatment for RFG and CG by translating the existing RFG VOC performance standard into an RVP per-gallon cap standard, as is the case for CG in the summer. In Section V.A.2, we describe how the proposed summer RVP per-gallon cap of 7.4 psi equates to the existing RFG summer VOC standards. This change alone allows for the removal of the sampling, testing, and reporting requirements associated with several Complex Model parameters, greatly simplifying compliance with our fuel standards. With this proposed translation of the RFG summer VOC performance standards into a summer RFG RVP per-gallon maximum standard, the required controls on fuel properties for RFG would be identical to the control of fuel properties for CG, even though the standards would remain different.

Second, since the standards for volatility, benzene, and sulfur would be treated similarly between RFG and CG, this would allow for the streamlining and consolidation of the compliance and enforcement provisions of the various part 80 fuel quality programs into a single fuel quality program. This consolidation would improve consistency, remove duplication, and ultimately reduce compliance burden on regulated parties and EPA. For example, we are proposing to consolidate the various gasoline reporting requirements into a single, unified annual reporting requirement. Under part 80, we require quarterly batch reports for RFG, versus annual reports for CG. We also require separate batch reports for the gasoline benzene and gasoline sulfur programs.

Third, the proposed streamlined fuel quality program aims to improve oversight of our fuel quality programs. We hope to accomplish this by updating and improving the third-party oversight programs we already use in part 80. We are proposing to consolidate the existing three in-use survey programs into a single national in-use fuel quality survey. This proposed program would help ensure that all fuels nationwide continue to meet EPA fuel quality standards when dispensed into vehicles and engines, not just at the refinery gate. We are also proposing to replace the RFG independent lab testing requirement with a voluntary national oversight program. This proposed sampling oversight program would impose substantially lower costs across industry than the current regulations while helping to ensure the consistency of sampling and testing across industry. Finally, we are proposing to update and modernize the annual attest engagement program. These updated procedures will help ensure that the quality and consistency of reported information. Taken together, we believe these proposals will help improve oversight of our fuel quality programs.

B. Summary of Stakeholder Involvement and Rule Development

We have actively engaged stakeholders throughout the development of this action to help maximize its potential effectiveness. Due to the number of affected stakeholders, the complexity surrounding the production and distribution of fuels, and the broad scope of this action, active stakeholder involvement was necessary to help ensure that the proposed fuels regulatory streamlining program achieved its goals.

As part of the proposal development process, we provided advance notice through four discussion drafts of the proposed regulations.[4] In doing so, we solicited feedback from stakeholders to: (1) Help ensure that any gaps in our regulatory requirements were filled prior to proposal; and (2) identify potential issues with the streamlined regulations. We also held a three-day public workshop on a variety of topics in Chicago on May 21-23, 2018.[5] During this workshop, EPA staff discussed a variety of issues related to the development of this action to an audience of over 120 affected stakeholders. We also reached out on at least two separate occasions to a broad spectrum of interested stakeholders, including parties that make and distribute fuels, states, environmental non-governmental organizations, and other affected stakeholders. The proposed streamlined fuel quality program in this action is intended to reflect the input of all of those who participated in these activities and events.

C. Timing

As discussed in more detail in Section III.B, we are proposing that the part 1090 regulations would mostly replace the existing part 80 regulations on January 1, 2021. We believe that having an implementation date at the beginning of a new compliance period would provide for a smooth transition to new regulatory requirements.

D. Costs and Benefits

We do not anticipate much, if any, change in air quality as a result of this action. This is largely due to the fact that we are not proposing changes to the existing fuel quality standards. As such, we do not expect that regulated parties would need to make significant changes to how fuels are made, distributed, and sold, which are the factors EPA typically considers when determining the costs associated with imposing or changing fuel quality standards.

However, we do believe that this proposal could result in savings to regulated parties and EPA by simplifying compliance with our fuel quality standards and by allowing greater flexibility in the manufacture and distribution of fuels. These savings would largely arise from the reduction of the administrative costs on regulated parties and EPA in complying with and implementing the existing fuel quality standards. We estimate the annualized total costs savings in administrative cost savings to industry to be $32.9 million per year. Other savings associated with improving the fungibility of fuel and providing greater flexibility could potentially be even more significant but are much more difficult to quantify. Section XIV of the preamble discusses in more detail the potential costs and benefits of this action.

II. Changes to Part 80

We are transferring several provisions in part 80 that are currently in effect to part 1090.[6] These provisions are all discussed in the subsequent sections of this preamble and are now drafted in a manner that makes them easier to understand. We are also proposing to remove subparts B, D, E, F, G, H, I, J, K, L, N, and O and appendices A and B to part 80. Some of these subparts have either expired (e.g., designate and track provisions for diesel fuel) or have been replaced by newer subparts (e.g., subpart K (RFS1) was superseded by subpart M (RFS2), subpart H (Tier 2 Sulfur) was supplanted by subpart O (Tier 3 Sulfur), and subpart J (MSAT1) was supplanted by subpart L (MSAT2)).

We are not transferring some provisions from part 80 to part 1090. First, we are retaining the existing Renewable Fuel Standard (RFS) provisions in subpart M. We are proposing minor edits to subpart M that are intended to ensure consistency with the new language used in part 1090. These edits will not affect any of the actual requirements in subpart M, but rather will homogenize the language used across all of our fuels programs.

Second, because we are retaining the RFS program in part 80, we need to maintain certain general provisions contained in subpart A that will continue to apply to the RFS program. We are also revising several sections within subpart A to remove requirements, such as definitions that would no longer be applicable to part 80. In addition, we are reorganizing and consolidating the definitions in 40 CFR 80.2 to place them in alphabetical order, as this would make it consistent with part 1090 and much easier to find terms.

Finally, we are also retaining the Oxygenated Gasoline provisions in subpart C in part 80. This subpart contains a single section related to a requirement for labeling of oxygenated gasoline at retail pumps, as mandated by CAA section 211(m)(4). We are maintaining this requirement in part 80 because some state oxygenated fuel programs may reference the labeling requirements in part 80 and we want to minimize the amount of changes needed by states to revise regulations and update state implementation plans.

III. Structure of Proposed Regulations and General Provisions

This section describes the general structure of the proposed part 1090 regulations (i.e., how we propose to structure the regulations to make them more accessible to users and readers of the regulations). This section also describes the proposed implementation dates, how we intend to deal with prior approvals made under part 80, and our proposed approach to consolidating the hundreds of definitions in the part 80 regulations. Finally, this section discusses key proposed provisions (e.g., the definition of gasoline) in more detail to solicit public feedback on terms fundamental to the proposed streamlined fuel quality program.

A. Structure of the Regulations

We are proposing a structure for part 1090 that differs from the structure of our current part 80 regulations. Part 80 includes a variety of fuel quality programs that, while designed to operate together, appear as distinct programs in the regulations. Historically, we have codified new fuel quality programs by adding a new subpart at the end of part 80. This was often done because each new fuel quality program implemented new regulatory requirements that augmented the prior fuel quality programs. These new additions also helped provide interim requirements needed to implement the new program. As a result, part 80 includes numerous similar sections that either create multiple methods of complying with certain regulatory requirements (e.g., submitting multiple gasoline batch reports for the RFG, antidumping, gasoline benzene, and Tier 2/3 gasoline sulfur programs) or create what might appear to be contradictions in the regulations. Rather than have subparts with all the provisions associated with a given fuel standard (e.g., a subpart that contains all provisions related to gasoline benzene and a separate subpart that contains all provisions related to gasoline sulfur), part 1090 contains dedicated subparts according to the various functional elements of our fuel regulations (e.g., subparts that contain all gasoline standards or contain all reporting requirements).

As proposed, subpart A contains general requirements that apply throughout the rest of part 1090. Subpart A includes regulatory language that generally outlines the applicability and scope of the regulation, defines key terms, and outlines when the part 1090 requirements come into effect. Subpart A also describes how requirements under part 1090 interact with other parts of the regulations that affect fuels—parts 79 and 80. Many of these sections are described elsewhere; for example, rounding of data is discussed in the reporting section (see Section VIII), and batch numbering is discussed in the designation and product transfer document section (see Section VIII).

We are also proposing to include a list of general regulatory requirements for parties in subpart B. This subpart would lay out the general regulatory requirements for regulated parties. This helps inform the regulated community of what is generally expected of them in a succinct manner and provides references to the specific requirements in the appropriate places in the regulations. While the roadmap in subpart B does not remove or modify any of the regulatory obligations required throughout the rest of part 1090, we believe it will serve as a helpful guide. During the development of this proposed rule, we received feedback from several stakeholders that such a roadmap would not only be helpful for them to follow the part 1090 regulations, but would especially help those new to the regulations more easily identify general regulatory requirements.

We are also proposing to keep the standards for different fuels in separate subparts so as to make it easier for parties to identify the specific standards that apply to fuels, regulated blendstocks, and additives. For part 1090, we have put the gasoline-related standards and the diesel-related (plus IMO marine fuel) standards in their own individual subparts. We are also leaving a subpart reserved after the gasoline and diesel standards, as we may need to use that subpart for future standards and this would enable us to not have to move subsequent subparts in a manner that would cause unnecessary confusion on the part of the regulated community.

The next block of subparts (E through P) involve the provisions and requirements that regulated parties are expected to follow to demonstrate compliance with the applicable standards. We have consolidated the specific types of compliance activities where possible. For example, we have consolidated all the registration sections of part 80 into a single registration subpart in part 1090 (subpart I). For these subparts, we have included general provisions that apply to all regulated parties, with sections devoted to specific requirements for individual groups of regulated parties (e.g., gasoline refiners or oxygenate blenders).

Subpart Q includes the liability, compliance, and violation provisions that EPA enforcement staff would use to enforce the program. This subpart consolidates the similar sections from across part 80 into a single streamlined subpart.

Finally, subpart R includes the attest engagement procedures that independent auditors would need to use to conduct annual auditing of reports and records for gasoline refiners. These procedures are updated versions of the those already included in part 80.

We believe that this new structure would make the fuel quality regulations more accessible to all stakeholders, help ensure compliance by making requirements more easily identifiable by activity, and help future participants in this regulated space understand our fuel quality regulations in the future. We seek comment on this proposed structure of the regulations.

B. Implementation Dates

We are proposing that regulated parties would begin complying with most provisions of part 1090 on January 1, 2021. This proposed date would result in the first compliance reports for the 2021 compliance period being due March 31, 2022, and the first attest engagement reports for the 2021 compliance period being due June 1, 2022.

We believe that this action minimizes the need for immediate changes to how regulated parties comply with our fuel quality regulations, and therefore, this proposed implementation schedule will allow sufficient time for regulated parties to modify their current business practices whenever it makes the most business sense for the individual regulated party's situation. In general, we have tried to minimize changes to existing requirements for regulated parties so as to avoid unnecessary burden. However, to consolidate the RFG program with the other fuel quality programs and maximize fuel fungibility, some changes to the program design would result from consolidating the programs into a single national program. Where possible, we wrote the proposed requirements to allow flexibility for regulated parties to adjust as needed.

While we believe a January 1, 2021, implementation date provides regulated parties enough time to come into compliance since we are not requiring changes that would necessitate substantive investments to meet new or modified fuel quality standards, we received feedback during the rule development process that we may need to provide regulated more time to implement some of the proposed provisions. In particular, some stakeholders noted that modifying product transfer document (PTD) language and adjusting to some of the proposed changes for sampling and testing may not be possible by January 1, 2021. One potential solution is to allow more time for these specific provisions to phase in. For example, we could allow regulated parties to continue to use the part 80 PTD requirements until the beginning or end of the high ozone season (June 1 and September 15, respectively). A similar approach could be allowed for other provisions that potentially need more lead time. We seek comment specifically on what provisions may require additional lead time to implement.

C. Prior Approvals

We are proposing to allow regulated parties with existing approvals under part 80 to maintain those approvals under part 1090. For example, parties registered under part 80 would not need to reregister under part 1090. We believe that making regulated parties resubmit information already reviewed and approved by EPA would be duplicative and burdensome on both the regulated parties and EPA staff. However, this action would require that any new requests or updates to approvals currently necessary under part 80 would have to meet the new proposed regulatory requirements of part 1090.

For existing approvals under part 80, regulated parties would not need to update a previously approved submission under part 1090. For example, we have approved alternative E15 labels under part 80. Parties would not need to have these labels reapproved in order to use them under part 1090. One notable exception is for in-line blending waivers. As discussed more in Section XIII.G, we are proposing significant changes to the in-line blending waiver provisions for RFG (mostly to remove provisions related to parameters that would no longer need to be reported) and for CG, which are designed to make consistent with the proposed RFG in-line blending waiver provisions. As such, we are proposing to require resubmission of all in-line blending waiver requests to ensure that they meet the new requirements.

D. Definitions

We are proposing to streamline and update the definitions contained throughout part 80, as well as add and remove terms as needed to write the proposed part 1090 regulations. How we define key terms in the regulations has a significant effect on how regulated parties comply with the regulations. As our fuel quality programs have expanded in scope, definitions in part 80 have expanded as well. Additionally, as we added new subparts to the part 80 regulations for each program, we have added subpart specific definitions. We have also defined terms in the context of specific sections of the regulations. This has created situations where sometimes there are differences in definitions for the different standards, which makes it more difficult for parties to comprehend and comply with the regulations. In part 1090, we have consolidated all the applicable definitions into a single section. We have tried to avoid having a definition section in individual subparts; however, some infrequently-used terms may still be defined in the context of the regulatory text. We believe this approach would help the regulated community and the public at large to more easily comprehend the regulations.

For the most part, we are proposing to transfer the existing part 80 definitions into part 1090 with minor proposed changes to specific terms for consistency. However, in some cases, we are proposing to redefine or reclassify key terms as part of part 1090. Specifically, these areas include the defined terms for the types of regulated products (discussed in Section III.D.1) and the descriptions of regulated parties (discussed in Section III.D.2). We are also proposing revisions to the definition of “gasoline” and “diesel fuel” (discussed in Section III.D.3). While we believe these three areas of the proposed definitions warrant significant discussion, we seek comment on all of the proposed definitions.

1. Fuels, Fuel Additives, and Regulated Blendstocks

In order to improve the clarity and consistency of our regulations, we are proposing changes regarding how to classify products regulated under our fuel quality regulations. In part 80, most fuel programs were written as a separate fuel program rather than a single, consolidated fuel quality program. For example, 40 CFR part 80, subpart I, almost exclusively deals with distillate fuels and 40 CFR par 80, subpart N, deals with gasoline-ethanol blended fuels. Since part 1090 would attempt to consolidate all fuel quality programs under part 80 into a single, consolidated fuel quality program, a consistent nomenclature for regulated products is needed.

This action describes requirements for fuel quality on three categories of products: Fuels, regulated blendstocks, and fuel additives. We further classify these products into bins based on the type of vehicle or engine that the fuel is used (i.e., gasoline-fueled, diesel fueled, or in a vessel subject to MARPOL Annex VI requirements (e.g., vessels that must use ECA or IMO marine fuel)). For gasoline-fueled engines, we not only define the term gasoline (discussed in detail in Section III.D.2), but we also define and place requirements on specific types of gasoline based on its ethanol content (e.g., E0, E10, and E15), whether the gasoline is intended for use or used as summer or winter gasoline, and in the summer, what RVP standard the fuel is subject to (i.e., 9.0 psi, 7.8 psi, or the proposed RFG 7.4 psi standard). For diesel-fueled engines, since the requirement to use 15 ppm diesel fuel (or ultra-low-sulfur diesel (ULSD)) is now required in almost all motor vehicle, non-road, locomotive, and marine applications (called MVNRLM diesel fuel in part 80), we are defining this fuel simply as ULSD, as it is more commonly known in the market. 500 ppm diesel fuel continues to be allowed for certain locomotive and marine applications.

Regarding regulated blendstocks, we have historically not imposed quality specifications on blendstocks, choosing instead to focus compliance requirements on finished fuels that are ultimately used in vehicles and engines. However, as the fuels marketplace has continued to evolve, this structure has become increasingly difficult to accommodate the complexity of manufacturing and distributing fuels practices today. Therefore, we are proposing alternative provisions, which are all currently permissible under part 80, for gasoline manufacturers to demonstrate compliance with our fuel quality requirements by imposing requirements on certain blendstocks that are added to previously certified gasoline (PCG) if certain conditions are met. We are referring to blendstocks for which we have proposed standards collectively as “regulated blendstocks.” For example, under both part 80 and the proposed part 1090 regulations, we allow gasoline refiners to blend butane into gasoline and to rely on test results from the producers of the butane if the butane meets more stringent sulfur and benzene per-gallon standards.[7] These butane blenders can use these provisions in lieu of certifying the finished gasoline and having to meet sulfur and benzene annual standards as these provisions are designed to ensure that the national sulfur and benzene pool do not increase as a result of blending these feedstocks. Under part 1090, we are proposing the same flexibilities as under part 80 for gasoline manufacturers that wish to blend butane that has been certified to meet specifications (differences between parts 80 and 1090 are discussed in Section V.A.3). We believe that this will also allow more opportunities for parties to make cost-effective compliant fuels in the future.

This action also includes the current part 80 specifications for gasoline and diesel additives, mostly unchanged. Except for oxygenates in gasoline, additives are added to fuels in low amounts (less than 1.0 volume percent of the fuel total) and often serve to help improve fuel performance (e.g., to control deposits on intake valves). All diesel fuel additives are subject to sulfur limitations. Under both part 80 and part 1090, gasoline additives are also subject to sulfur limitations, but the term “gasoline additives” also includes gasoline detergents and oxygenates. Also under both part 80 and part 1090, gasoline detergents and oxygenates (including denatured fuel ethanol or DFE) have specific requirements that apply in addition to the sulfur requirements that apply for all gasoline additives.

2. Fuel Manufacturers, Regulated Blendstock Producers, and Fuel Additive Manufacturers

In part 80, a refinery is defined as ” any facility, including but not limited to, a plant, tanker truck, or vessel where gasoline or diesel fuel is produced, including any facility at which blendstocks are combined to produce gasoline or diesel fuel, or at which blendstock is added to gasoline or diesel fuel,” [8] while a refiner is “any person who owns, leases, operates, controls, or supervises a refinery.” [9] When these terms were first defined, virtually all finished fuels were produced at a crude oil refinery. As we have permitted greater flexibility in the production of fuels through the blending of regulated blendstocks to make new fuels and the market has moved to allowing fuels to be produced downstream of crude oil refineries, the use of the term “refiner” to encompass all parties that make fuels has become less appropriate. Additionally, the differences in terminology between part 79 and part 80 have caused confusion among those required to or potentially required to comply with the requirements of both parts. Refiners and importers of on-highway motor vehicle gasoline and diesel fuel are fuel manufacturers under part 79 and required to register under EPA's fuel and fuel additive registration (FFARs) requirements. Under part 79, parties that make gasoline or diesel fuel through the blending of blendstocks or blending of blendstocks into PCG are also considered fuel manufacturers and must registered under part 79. Part 79 also includes importers of on-highway motor vehicle gasoline and diesel fuel as fuel manufacturers for purposes of FFARs. Part 80 generally requires that importers of gasoline and diesel fuel meet the same requirements as refiners, with some additional requirements on importers depending on the situation.

This action uses the term fuel manufacturer to describe any party that owns, leases, operates, controls, or supervises a facility where fuel is produced, imported, or recertified, whether through a refining process (e.g., through the distillation of crude oil), through blending of blendstocks or blending blendstocks into a previously certified fuel to make fuel, or through the recertification of products not subject to our fuel quality standards to fuels that are subject to our fuel quality standards (e.g., redesignating heating oil to ULSD). Importers of fuels would continue to be fuel manufacturers consistent with parts 79 and the CAA. We are also proposing to further distinguish between parties that refine feedstocks to make fuels (more commonly known as “crude refiners”) and blending manufacturers who make fuels through blending blendstocks together to make a fuel or into an existing fuel to make a new fuel.[10] This action includes requirements specific to the type of fuel manufacturer, and the proposed nomenclature makes it easier for us to describe the proposed requirements for the types of fuel manufacturers and for parties to understand what requirements apply specifically to whom. However, while we are proposing to modify the terminology used in part 1090 for these parties, generally, these parties would have the same obligations and responsibilities under the regulations.

We are proposing to define producers of regulated blendstocks as regulated blendstock producers. For example, these parties would include certified butane/pentane producers and oxygenate producers (including DFE producers).

As is the case currently under parts 79 and 80, parties that only blend fuel additives into fuels are not fuel manufacturers. Any party that adds a compound (other than oxygenate or transmix) that is 1.0 percent or more of the finished fuel would be a blending manufacturer, as the compound added would be considered a blendstock and parties that add blendstocks into fuel are considered fuel manufacturers and would need to meet all the applicable regulatory requirements. Consistent with part 79, oxygenate blenders that only add oxygenates at levels permissible under the CAA section 211(f) continue to be considered additive blenders and not fuel manufacturers.

3. Definition of Gasoline

This action includes a new definition of gasoline. When we define what constitutes a fuel, this determines which fuels are subject to our fuel quality standards. The goal of our fuel quality programs is to ensure that compliant fuel is ultimately used in vehicles, engines, and equipment. To achieve this goal, we believe that the definition of gasoline needs to reflect changes in the fuels marketplace that have occurred over the last 40 years, as well as potential changes on the horizon. While petroleum refineries still have the most direct impact on gasoline fuel quality by volume, every party downstream of the refinery can affect fuel quality, and in today's marketplace many of these downstream parties are now the determinant of the quality of the fuel that actually goes into the vehicle. For example, these parties may add oxygenates (primarily ethanol) or augment the volume of gasoline through the blending of various blendstocks into PCG to produce new fuels.

To ensure that gasoline meets fuel quality standards from the petroleum refinery until it is dispensed into a gasoline-fueled vehicle or engine, in light of the changing fuels marketplace, we believe that the definition of gasoline should contain three elements. First, when a party represents a fuel as meeting our fuel quality standards, such fuel is subject to our standards regardless of whether the fuel meets the standard. Were this not the case, then anytime a fuel failed to meet our standards, we could not hold anyone accountable for failing to meet the standards. In the proposed definition of gasoline, we define gasoline as anything commonly and commercially known as gasoline. This portion of the proposed definition is consistent with the existing parts 79 and 80 definitions of gasoline.

The second element of the definition of gasoline is whether the product is made available for use or used in a gasoline-fueled vehicle or engine. Since the ultimate purpose of our fuel standards is to ensure that compliant fuel is used in vehicles and engines, if a person makes a product available for use by designating it as gasoline or placing it in the fuel distribution system, or if the product is used in a gasoline-fueled vehicle or engine, the product should be subject to EPA standards. We have used this terminology when describing other fuels under part 80, notably in definitions related to motor vehicle diesel fuel [11] and ECA marine fuel.[12]

The third element of the definition of gasoline is the product's physical and chemical characteristics. Whether a fuel is subject to our standards cannot be solely based on whether a regulated party calls or labels a product it produces as gasoline. This would create an incentive for parties to simply label fuel intended for use as gasoline by another name to avoid having to meet our fuel standards. Therefore, when a manufacturer produces a fuel that is chemically and physically similar to gasoline, the fuel should be subject to our gasoline fuel standards. To address this element, we are proposing that gasoline is any product that meets the voluntary consensus standards body (VCSB) industry specifications for gasoline (ASTM D4814).

For the discussion drafts of the regulations,[13] we presented definitions of gasoline that attempted to conservatively capture any product that could be used in vehicles and engines designed to operate on gasoline. We received feedback from stakeholders suggesting that this definition of gasoline was too broad, especially concerning the third element, which would have resulted in blendstocks that are never intended to be sold in their pure form as gasoline being subject to our fuel quality standards. These stakeholders argued that some higher quality blendstocks (e.g., alkylates) used to make gasoline would meet the ASTM D4814 specifications for gasoline and may therefore be subject to EPA standards. To address this feedback, we have excluded those blendstocks of concern that are not made available as gasoline but may otherwise meet the definition of gasoline by meeting ASTM D4814 specifications. Since there is an economic incentive for parties to keep these high value blendstocks segregated from gasoline in the fuel distribution system, these products will not generally be made available for use in gasoline-fueled vehicles and engines and would not, therefore, be considered gasoline. We seek comment on this approach.

We have taken a similar approach in the part 80 definitions for diesel fuel and largely mirror the three elements proposed for the definition of gasoline in the definition of diesel fuel. We seek comment on these definitions.

IV. General Requirements for Regulated Parties

As part of the streamlined fuel quality program, we are proposing a subpart dedicated to outlining the general regulatory requirements for each regulated party (subpart B). We received feedback during the rule development process that due to the layout of the regulations in part 80, parties need to read the entire subpart to make sure they have identified all applicable regulatory requirements. The current regulations in part 80 are almost 1,000 pages long, and many regulated parties spend a substantial amount of resources to comprehend and interpret them or ask EPA staff through the help desk to identify applicable regulatory requirements.

To make the streamlined regulations more accessible, we are proposing to make subpart B a roadmap for regulated parties, directing them to those subparts that are most likely to affect them and their business. We first outline the general requirements applicable to all parties that make and distribute fuels, fuel additives, and regulated blendstocks. These requirements include keeping records and being subject to regulatory requirements under the proposed subpart if a party makes and distributes fuels, fuel additives, and regulated blendstocks.

We then describe the requirements that apply to each group of regulated parties based on their business activities. Examples of these categories are fuel manufacturers, detergent blenders, oxygenate blenders, and retailers. We believe this would help these parties more easily identify regulatory provisions that apply to their specific activities. For example, retailers are typically small businesses that have greater difficulty affording consultants to help them understand their regulatory requirements. Retailers also have a relatively small number of regulatory requirements under the part 80 and part 1090 regulations. By identifying the generally applicable requirements that apply to all retailers, these small businesses could more easily identify those regulatory requirements that apply to them, helping them to more easily comply with our fuel quality regulations.

It is important to note that parties may have more than one regulated activity, and, as is the case today, these parties would be required to satisfy all regulatory requirements for each regulated activity. Regulated parties would still need to comply with all applicable requirements contained in part 1090, regardless of whether they are identified for them in subpart B. EPA cannot predict every possible situation a party may be in within the market place now or in the future. Accordingly, regulated parties, as always, should pay careful attention to all the applicable regulatory requirements to ensure compliance.

We request comment on the proposed structure of subpart B, as well as whether the subpart would be helpful to regulated parties in general. We also request comment on how we can improve the streamlined regulations to further improve the understandability and navigation of part 1090.

V. Standards

A. Gasoline Standards

1. Overview and Streamlining of Gasoline Program

We are proposing to consolidate the various gasoline-related standards into a single subpart in part 1090 (subpart C). We are not proposing to change the lead, phosphorous, sulfur, benzene standards or the RVP gasoline standards in the summer, nor are we proposing to change the standards for oxygenates (including denatured fuel ethanol), certified ethanol denaturant, gasoline additives, and standards for certified butane and pentane. These standards are simply being moved and consolidated into subpart C. Any comments on these standards will be treated as beyond the scope of this rulemaking.

However, to streamline the gasoline program, we are proposing some changes in the form of the RFG VOC performance standards. These changes are not expected to change the stringency of the gasoline standards. We do, however, expect that these changes would greatly simplify the gasoline program, resulting in: (1) Reduced burden associated with demonstrating compliance with the gasoline standards; (2) improved fungibility of gasoline, allowing the market to operate more efficiently; and (3) reduced costs to consumers. First, we are proposing to translate the RFG standard from the demonstration of the VOC performance standard via the complex model into an equivalent maximum RVP per-gallon standard, which would allow us to greatly simplify the compliance demonstration requirements for RFG. Of all the provisions being proposed, this is the key provision enabling considerable streamlining of our existing gasoline regulations.

Second, we are also proposing to consolidate the two grades of butane and the two grades of pentane specified in part 80 for use by butane and pentane blenders into a single grade each of certified butane and certified pentane. This would greatly simplify the registration and reporting of activities related to blending certified butane and certified pentane.

Finally, we are proposing certain regulations related to summer gasoline, as well as procedures for states to relax the federal 7.8 psi RVP standard. These changes are discussed more thoroughly in the following sections.[14]

2. Reformulated Gasoline Volatility Standard

The RFG program was created by EPA in the 1990s in response to a directive from Congress in the CAA Amendments of 1990 with the express purpose of providing cleaner burning gasoline to the most polluted metropolitan areas of the country. The program was very successful in that regard. However, since that time, a series of additional fuel quality standards and other market changes have resulted in CG meeting or exceeding most of the performance requirements for RFG, with the primary difference between CG and RFG now being only the lower RVP of the RFG during the summer months. At the same time, the extensive RFG regulations remain, constraining gasoline fungibility, increasing costs, complicating compliance oversight, and limiting the sale of certain biofuel blends. Consequently, we are proposing to: (1) Replace the existing compliance mechanism used for RFG batch certification—the Complex Model—with a summer RVP maximum per-gallon standard; (2) apply that same single RVP standard to all RFG nationwide; (3) provide greater flexibility for blending of oxygenates (ethanol and biobutanol) and E0 in RFG areas; and (4) remove a number of other restrictions that now create a distinction without a difference between RFG and CG.

We intend these proposed changes to maintain the stringency of all standards associated with RFG while alleviating unnecessary compliance mechanisms by simplifying the recordkeeping and reporting requirements. We acknowledge that the CAA requires the existence of RFG in specified nonattainment areas [15] and certification procedures to certify RFG as complying with the requirements.[16] This action proposes to simplify and translate those requirements while still maintaining the same level of VOC emissions reductions as currently required. This would be accomplished by translating the current VOC emissions reductions demonstrated through the Complex Model into an RVP standard that would be used to demonstrate RFG VOC compliance in lieu of the Complex Model.[17]

CAA section 211(k)(3)(B) provides that during the high ozone season, “the aggregate emissions of ozone forming volatile organic compounds from baseline vehicles when using the reformulated gasoline shall be 15 percent below the aggregate emissions of ozone forming [VOCs] from such vehicles when using baseline gasoline.” This section also provides for increasing stringency beginning in 2000 of at least 25 percent, based on technological feasibility and costs. We are achieving that demonstration through the use of an RVP standard.

The proposed RFG summer RVP standard of 7.4 psi was specifically chosen in order to maintain the summer VOC performance required by the statute,[18] and this RVP is currently observed in the RFG fuel pool; this approach also aligns the RFG compliance provisions with the much simpler and more easily enforced provisions currently in place for CG. In doing so, we are also acting on the Energy Policy Act of 2005 (EPAct) directive to consolidate the RFG VOC Regions into a single set of RFG standards by applying the southern RFG requirements (VOC control region 1) to all RFG areas, as discussed further in Section V.A.2.d. This consolidation of RFG VOC Regions, along with other proposed changes in this action, would provide greater fungibility in the RFG pool and eliminate antiquated restrictions in order to provide greater flexibility to fuel manufacturers and distributors, reduce cost for those parties, and reduce compliance and enforcement oversight costs.

Additional benefits from this proposed action are potentially wide reaching and could create opportunities for broader availability of fuels and reduced consumer costs. With the introduction of a summer RVP standard for RFG, in situations of fuel shortage in RFG areas, gasoline from other RFG areas or from state low-RVP fuel programs could now be moved to affected areas without recertification so long as the RFG RVP standard is observed. This increase in gasoline fungibility should serve to reduce scarcity and promote lower prices for consumers in affected areas. Additionally, the desire for ethanol-free gasoline for marine use in RFG areas has regularly been expressed by both citizens and elected officials of areas where RFG is required. Under the current RFG compliance provisions in part 80, it is difficult for distributors to provide ethanol-free gasoline to consumers in RFG areas. Under part 1090, it would be easier for distributors to provide ethanol-free gasoline to consumers in these areas.

a. Review of RFG

The definition and use of RFG is stipulated in CAA section 211(k). The RFG program was established in response to exceedances of the National Ambient Air Quality Standards (NAAQS) for ozone being experienced in many metropolitan areas across the U.S. in the late 1980s.[19] Gasoline motor vehicle emissions were and continue to be a major contributor to the inventory of air pollutants in metropolitan areas. The RFG program is implemented through a set of gasoline standards demonstrated to reduce emissions from vehicles of that era.[20] The demonstration of emissions reductions was predicated on changing fuel properties from a baseline fuel composition used in the baseline vehicle fleet. The 1990 statutory baseline fuel and fleet codified in the RFG regulations in part 80 are presented in Table V.A.2.a-1.

Open Table

Table—V.A.2.a-1—Statutory Baseline Fuel Composition

E200 (%) 41.0 50.0
E300 (%) 83.0 83.0
Oxygen (wt%) 0.0 0.0

The compliance of RFG in comparison to the baseline fuel was originally demonstrated by refiners using the Simple Model.[21] An improved version of the compliance model was created and designated the Phase II Complex Model after the initial phase of the RFG program. The Complex Model has been used by refiners to certify RFG under the Phase II RFG program and to meet the emission reduction standards outlined in Table V.A.2.a-2.

Open Table

Table V.A.2.a-2—Phase II Standards and Requirements for Compliance

Phase II Complex Model Averaged Standards
VOC Emission Performance Reduction (%):
Region 1 standard ≥ 29.0
Region 1 per-gallon standard ≥ 27.5
Region 2 standard ≥ 27.4
Region 2 per-gallon standard ≥ 25.9
Region 2 (Chi/Milw) standard ≥ 25.4
Region 2 (Chi/Milw) per-gallon standard ≥ 23.9
Toxic Air Pollutants Emission Performance Reduction (%) ≥ 21.5
NOX Emission Performance Reduction (%):
Gasoline designated as VOC-controlled ≥ 6.8
Gasoline not designated as VOC-controlled ≥ 1.5
Benzene (vol%):
Standard ≤ 0.95
Per-gallon maximum ≤ 1.30

The Complex Model required refiners to sample and test RFG for 11 parameters that would then be entered into the model. Refiners could either demonstrate compliance on a per-gallon basis or on an average basis across the year. Despite the added flexibility associated with the Complex Model over the Simple Model, refiners tended to focus changes on just a few parameters. To comply with the VOC emissions performance standard, refiners primarily lowered the RVP of their RFG as was anticipated at the time of the rule. For the NOX standard, refiners primarily lowered the sulfur content of RFG, and to comply with the toxics standard, benzene and aromatics content was reduced in their RFG. Additionally, there have been three different RFG VOC regions designated under the Phase II standards; each with slightly different required levels of VOC emissions reduction as compared to the baseline fuel. The RFG program operated under these standards and resulted in a gasoline composition that was vastly different from CG when the program was phased in from 1995 through 2000.

b. Gasoline Regulation Changes

Since 2000, however, through a series of gasoline regulations and marketplace changes, the environmental performance of CG has improved to equal that of RFG in all respects except for summer VOC emission performance (as estimated using the Complex Model).

We established the Tier 2 gasoline sulfur program to limit the average sulfur content in gasoline to 30 ppm beginning in 2004,[22] with an 80 ppm per-gallon maximum standard (95 ppm at any location downstream of a refinery or import facility).[23] A reduction in fuel sulfur would reduce NOX emissions on its own accord (as expressed in the Complex Model), but fuel sulfur reduction was also paramount to protecting the exhaust aftertreatment systems necessitated by the more stringent vehicle emission standards established as part of the same Tier 2 program rulemaking. By the end of 2007, after the conclusion of all early credit, small refinery hardship extensions, and other program flexibilities, the sulfur level of all gasoline was reduced to less than 30 ppm in-use. The Tier 2 gasoline sulfur standards reduced VOC, NOX, and air toxics emissions, and brought down RFG and CG sulfur levels to a low enough level that the NOX emission performance standard determined using the Complex Model were met and exceeded for any compliant RFG. Consequently, the NOX emission performance standard was thereafter deemed met for both RFG and Antidumping (i.e., CG) if the Tier 2 gasoline sulfur standard was met. This represented the first time that gasoline standard for CG exceeded an RFG performance standard (the NOX performance standard in this case) on average, but it also heralded the convergence in gasoline quality between CG and RFG that would continue to occur over the next decade.

In 2007, EPA revised the original Mobile Source Air Toxics (MSAT) Rule with the MSAT2 Gasoline Benzene Program.[24] This rulemaking established an annual average standard of 0.62 volume-percent benzene on refiners and importers of gasoline.[25] This standard took effect starting January 1, 2011, for non-small refiners and January 1, 2015, for small refiners. The standard was fully phased-in on January 1, 2018. The result was that the air toxics performance standards for RFG were surpassed by the MSAT2 benzene standards for CG. Consequently, fuels that met MSAT2 benzene standards were deemed compliant with the air toxics emission performance standard otherwise calculated using the Complex Model. The rationale held, as with Tier 2, that any fuel meeting the new standard would meet or exceed the reductions required by the statute. The MSAT2 rulemaking also eliminated the NOX emissions performance reduction demonstration in the Complex Model as a result of the gasoline sulfur program.[26]

The combined effect of the sulfur and benzene gasoline standards has been that the use of the Complex Model has been narrowed to only demonstrating compliance with the summer VOC emission performance standard for RFG. While all of the Complex Model fuel parameters (except benzene) play a role in determining VOC emission performance, by far the primary lever for refiners to use to comply with the VOC emission performance standard is RVP.[27] Given that the changes to all the other fuel parameters are dictated by other vehicle standards and market requirements, refiners today primarily only lower RVP to the degree necessary (due to cost reasons) in order to meet the VOC emission performance standard of RFG. However, the degree to which refiners have needed to reduce the RVP of RFG to demonstrate compliance using the Complex Model has relaxed slightly over time with other changes, mandated and market, to gasoline.

In 2014, EPA finalized the Tier 3 gasoline sulfur program to further limit the average sulfur content in gasoline to 10 ppm beginning in 2017.[28] All refineries and importers, including small refiners and small volume refineries, must comply with the 10 ppm Tier 3 sulfur standard starting January 1, 2020. The Tier 3 sulfur standard resulted in further reductions in VOC, NOX, and air toxics emissions predicted by the Complex Model.

Beginning in the early 2000s, the amount of gasoline blended with 10 percent ethanol also increased markedly as a result of MTBE bans, rising crude oil prices, tax incentives, and the Renewable Fuel Standard (RFS) mandates. The addition of ethanol reduced the aromatic, olefin, T50, and T90 levels of gasoline, which together with the oxygen content reduced the VOC, NOX, and air toxics emissions predicted by the Complex Model. Similarly, since about 2009, reduced natural gas prices brought on by the proliferation of hydraulic fracturing technology has allowed refiners to more economically back off on gasoline reforming, continuing to reduce gasoline aromatic levels and in turn reducing VOC, NOX, and air toxics emissions predicted by the Complex Model.

The progression in gasoline sulfur, benzene, and aromatic content, RVP, distillation, and other Complex Model parameters is documented in the Fuel Trends Report released by EPA in 2017.[29] The evolution of these other Complex Model parameters over the past decade has allowed for a slight increase in RVP, as seen in Figure V.A.2.b-1.

RVP is the only one of the Complex Model parameters that affects evaporative emissions; the other fuel parameters (except benzene and including RVP) impact VOC exhaust emissions under the Complex Model. As a result, there are limits to the extent that these other fuel parameters can impact VOC emissions performance under the Complex Model and corresponding limits to the extent that RVP can be increased within the Complex Model and still result in a compliant RFG.[30] Figure V.A.2.b-2 shows the 95th percentile of RVP levels from the batch compliance data EPA receives.

c. Proposed RVP Standard for VOC Performance Determination

With the importance of RVP in the Complex Model for VOC emissions performance and the combination of MSAT2 and Tier 2/3 for reducing benzene and sulfur, respectively, RFG compliance is now almost completely determined by the RVP of the fuel. Consequently, an opportunity for greatly simplifying the certification process for RFG has presented itself. The 11 parameters required to certify RFG under the Complex Model could be reduced to just three (sulfur, benzene, and RVP) if a summer RVP standard were adopted along with the existing sulfur and benzene content standards.[31] Therefore, we are proposing that any RFG batch meeting a summer RVP standard of 7.4 psi RVP would be deemed in compliance with the RFG VOC emission performance reduction standard. Along with RVP, benzene concentration for MSAT2 compliance, and sulfur content for Tier 3 compliance would also be reported to EPA. Thus, all three of the emission reduction standards for RFG would be covered by just three parameters: RVP, benzene, and sulfur. This would reduce the compliance and reporting burden for fuel manufacturers by reducing the number of parameters they need to test and report from 11 to as few as three in the summer.[32]

In Section V.A.2.e, we lay out the process and rationale for the proposed summer RVP per-gallon standard of 7.4 psi for RFG. The primary intent in proposing to translate the VOC performance standards into an RVP maximum per-gallon standard is to maintain the status quo and to ensure that the emission reduction targets for RFG would continue to be achieved. During the selection process of the proposed summer RVP standard, we operated under the statutory constraints that were, and remain, present for the formulation of the Complex Model—namely, the 1990 baselines for both fuel composition and vehicle technology. Thus, the proposed 7.4 psi RVP standard for RFG would maintain the gasoline quality and its associated emission performance as calculated consistent with the statutory requirements and the Complex Model.

Although it will no longer be required for demonstration of RFG batch compliance, the Complex Model will be retained by EPA for compliance oversite purposes in conjunction with the proposed national fuel survey program. Continued adherence to the VOC emission performance reduction standard will be monitored through samples collected from RFG areas as part of the survey. This oversite function will help ensure that the emission reductions the Complex Model was intended to certify at the refinery gate are being maintained in use.

d. Consolidation of RFG Areas

Translating the VOC emissions performance standard into a summer RVP standard would enable EPA to simplify the RFG program significantly. Additionally, the creation of a single summer RVP standard for all RFG areas would further simplify the RFG program and automatically consolidate the VOC regions as required under section 1504(c) of EPAct.[33] Section 1504(c) directs EPA to revise the RFG regulations to consolidate the regulations for the VOC-Control Regions by eliminating the less stringent requirements.

In practice, there have been three sets of VOC emission performance standards for the VOC Regions of the RFG program: VOC-Control Regions 1 and 2, along with the adjustment to Region 2 provided for the Chicago/Milwaukee areas. To date, EPA has not taken action to consolidate the VOC regions as directed by EPAct. However, the creation of a single summer RVP standard provides both an opportunity and a mechanism by which to act on this requirement. A benefit of this consolidation would be the increased fungibility of RFG amongst historically distinct VOC-control regions.

We find that the EPAct language provides EPA with an additional source of authority to take this action to translate the VOC performance standard into a single RVP standard.

e. Translating the VOC Performance Standard to a Summer RVP Standard

In order to translate the VOC performance standard into an RVP cap, we utilized the Complex Model and the 1990 baseline fuels and vehicles to determine the corresponding RVP. In accordance with EPAct, the VOC-Control Region 1 emission reduction standards were used to establish the consolidated RVP standard. More specifically, the per-gallon reduction requirements for VOC-Control Region 1 from 40 CFR 80.41 were used as the basis for determining the summer RVP standard. Given that we are proposing a per-gallon standard, it was deemed the most appropriate point of reference for determining the required VOC reduction from the statute. We recognize that the current RFG summer VOC performance standards under part 80 allow for refiners and importers to meet either a per-gallon summer VOC performance standard or an annual average summer VOC performance standard. We are proposing to replace all RFG summer VOC performance standards with a maximum RVP per-gallon standard translated from the RFG Region 1 summer VOC performance per-gallon standard. Under this proposal, fuel manufacturers would no longer comply through an annual average standard and must instead demonstrate compliance on a per-gallon basis during the summer.

The intention of this proposed action is to maintain the level of stringency observed in the RFG pool while transitioning away from using the Complex Model to demonstrate compliance to instead demonstrate compliance with a summer RVP standard. To that end, the starting point for our analysis was the batch reports submitted to EPA in the course of certifying batches of RFG. Several years were evaluated, but the most recent full year of data at the time the analysis was carried out was 2018. Summary statistics, based upon volumetrically weighting the batches, for the Complex Model parameters for this data are presented in Table V.A.2.e-1.

Open Table

Table V.A.2.e-1—Summary Statistics for 2018 RFG

Weighted 5% Weighted 25% Weighted median Weighted 75% Weighted 95% Volume weighted average
Oxygen (wt%) 3.37 3.46 3.51 3.57 3.65 3.52
Sulfur (ppm) 4 10 18 26 42 19.3
Aromatics (vol%) 6.2 12.7 16.3 20 26.6 16.3
Olefins (vol%) 1.5 5.9 10.9 14.3 17.8 10.25
Benzene (vol%) 0.19 0.38 0.5 0.67 0.93 0.53
Ethanol (vol%) 9.23 9.46 9.61 9.77 10 9.62
E200 (%) 41.7 45.7 48.5 50.7 55.4 48.4
E300 (%) 81.4 84.1 86.5 88.9 92.6 86.6

There are only eight fuel parameters reported in Table V.A.2-5 because the remaining three parameters in the Complex Model (MTBE, ETBE, and TAME) have become negligible in the past 15 years, in part due to the removal of the RFG minimum oxygenate content requirement. The reported eight fuel parameters were then used to statistically construct “percentile” fuels based on how each of the eight parameters affected VOC performance in the Complex Model. For instance, the “5th” percentile is comprised of the 5th percentile values of Ethanol, E200, and E300 along with the 95th percentile values for aromatics, olefins, sulfur, and benzene. This combination results in the strictest set of parameters for RVP control and consequently the lowest, or “5th” percentile of allowable RVP. The parameter values for the 5th, 50th, and 95th percentile [34] RFG are reported in Table V.A.2.e-2, along with the volume-weighted average for each of the parameters for 2018 RFG.

Table V.A.2.e-2—Meeting the Phase II VOC Performance Standard for 2018 RFG

Fuel Oxygen (wt%) Sulfur (ppm) Aromatics (vol%) Olefins (vol%) Benzene (vol%) E200 (vol%) E300 (vol%)
5th 3.37 42 26.6 17.8 0.93 41.7 81.4
50th 3.51 18 16.3 10.9 0.5 48.5 86.5

Average 3.51 19.3 16.3 10.3 0.53 48.4 86.6

Each of the four fuel compositions in Table V.A.2.e-2 was then exercised in the Complex Model in order to solve for the maximum allowable RVP while still meeting the VOC emissions reduction requirement. The maximum allowable RVP was calculated for both the average and per-gallon standards for VOC-Control Region 1 and are reported for each of the four compositions in Table V.A.2-7.

Percentile Volume-weighted average
5th 50th 95th
VOC-Control Region 1 Maximum Allowable RVP Level
Average Standards 6.7 7.14 7.24 7.12
Per-Gallon Standards 6.90 7.30 7.40 7.29

As would be expected, the volume-weighted average allowable RVP of 7.12 is nearly identical to the 7.11-7.14 range that was observed in the 2012-2017 batch report data presented in Figure V.A.2.b-1. This reflects the widespread use of the average standards by most RFG fuel manufacturers under the current program. The per-gallon standards would have theoretically allowed for a ~0.15 psi higher RVP across the average RFG fuel pool, but fuel manufacturers have predominantly used the average standards. The percentile fuel compositions demonstrate that there is the potential for approximately a half-pound variation in RVP for a compliant RFG fuel depending on the balance of the other fuel parameters. However, there are two important results from this analysis: (1) Solving for maximum allowable RVP for the volume-weighted average fuel yields a very similar RVP as observed in the batch reports (~7.1 psi); and (2) the per-gallon standards would have allowed for a pool average RVP of nearly 7.3 psi with no changes to RFG fuel composition.

Therefore, we believe that the proposed 7.4 psi RVP standard for RFG is appropriate.[35] The proposed standard equates to a 27.5 percent reduction in VOC emissions performance as compared to baseline gasoline used in baseline vehicles (i.e., 1990 vehicles) using the Complex Model. We seek comment on the proposed 7.4 psi RVP standard.

f. Conventional Gasoline Batch Data Analysis

In order to translate the existing RFG VOC performance standard as an RFG summer RVP maximum per-gallon standard, it is necessary to evaluate how RVP per-gallon maximum standards are treated in practice. In order to evaluate the treatment of an RVP per-gallon maximum standard, we examined the RVP levels in relation to the 9.0 psi standard for CG in 2016.[36] To conduct the analysis, the batch reports were submitted to thorough quality control and assurance in order to ensure that only batches adhering to the 9.0 psi standard (boutique, federal 7.8 psi, etc. were all removed) and that contained less than one percent ethanol were considered.[37] The summary statistics for the 2016 summer CG batches are presented in Table V.A.2.f-1.

Open Table

Table V.A.2.f-1—CG Summary Statistics From the 2016 Batch Reports

Summer CG
Percentile RVP Volume above Volume below
5th 7.32 27,187,626,247 1,420,043,309
50th 8.67 12,984,692,750 15,622,976,806
95th 8.99 1,194,383,604 27,413,285,952
Mean 8.47 18,762,397,380 9,845,272,176
Standard 9.0 489,040,207 28,118,629,349

The CG batch data is represented in histogram form in Figure V.A.2.f-1. The graduations of 0.1 psi on the x-axis allow for a clearer representation of where the bulk of the fuel resides in relation to the 9.0 psi RVP standard.

The data from the CG batch reports show that the median RVP (8.67 psi) is approximately 0.3 psi below the 9.0 psi RVP standard. As would be expected, there is variability in the fuel batches, but the mode of the data is 0.2 psi below the standard and more than 95% of the CG fuel volume is below the standard. For CG, the mode fell 0.2 psi below the standard and the median fell 0.3 psi below the standard. This information was taken along with the average RVP of 7.12 psi for 2018 RFG discussed in Section V.A.2.e to conclude that a summer RVP standard for RFG of 7.4 psi would meet the goal of preserving the current environmental performance of RFG, while imposing little to no additional industry burden based upon the batch reports for CG. We seek comment on whether there would be additional industry burden associated with the proposed 7.4 psi RVP RFG standard.

g. Additional Changes Related to RFG

We are also proposing regulations intended to allow for greater compliance flexibility and increased gasoline fungibility for the RFG program. Specifically, in Section VIII.G we are proposing to address several provisions regarding fuel certification and recertification that are now commonplace due to the gasoline quality standards implemented since the onset of the RFG program. For instance, RFG is statutorily required to be used in certain ozone nonattainment or maintenance areas in both summer and winter. The differences between RFG and CG that require the respective fuels to be segregated in the summer (i.e., RFG and CG must meet different standards in the summer) are not present during the winter season, where RFG and CG must meet identical standards under part 80. However, a similar prohibition on co-mingling RFG and CG in the winter exists.

To address this situation, we are proposing to allow all winter gasoline to be used in RFG areas without recertification. Distributors of gasoline would be allowed to designate winter gasolines without recertification as RFG or CG to comport with state or pipeline specifications, which may require those distinctions. We are also proposing provisions to allow California manufacturers and distributors the flexibility to ship California gasoline and diesel fuel to the rest of the U.S. due to their state specifications meeting or exceeding EPA's standards. Lastly, new recertification standards are being proposed to facilitate end-of-season recertification, emergency fuel waivers, and allow greater downstream flexibility. These provisions are discussed in more detail in Section VIII.G. We seek comment on the proposed approach.

3. Certified Butane and Pentane

We are proposing to streamline the provisions for gasoline blending manufacturers that blend butane and pentane of certified quality (certified butane and certified pentane, respectively) into PCG.[38] Under part 80, these flexibilities allow gasoline blending manufacturers to rely on test results by the butane or pentane producer rather than testing each batch of butane or pentane received as would otherwise be required of a gasoline blender manufacturer to demonstrate compliance with EPA standards. This approach would be maintained in part 1090.

We are proposing to combine these grades into single grades of “certified butane” and “certified pentane.” Part 80 currently has two grades of butane and pentane (commercial and noncommercial) that can be used by gasoline blender manufacturers under these provisions. During the rule development process, many stakeholders highlighted the burden of demonstrating compliance with the part 80 butane and pentane blending provisions. We believe that, coupled with other changes to the specifications for certified butane and certified pentane described in this section, there is an opportunity to consolidate the grades of butane and pentane. This would allow for a streamlining of the compliance demonstrations needed for certified butane and certified pentane blenders to produce gasoline using certified butane and certified pentane.

The current standards in part 80 for commercial and noncommercial grades of butane and pentane contain specifications on the maximum sulfur, benzene, olefin, and aromatics content. Consistent with the proposed changes to RFG certification,[39] we are proposing to remove the maximum olefin and aromatics standards from the specifications for certified butane and certified pentane as we are proposing to no longer require those parameters for the certification of gasoline, as discussed in Section V.A.2, and because we do not expect issues to occur with other regulated parameters. Both certified butane and pentane would be subject to a maximum 10 ppm sulfur standard and maximum 0.03 volume percent benzene standard as are the commercial and noncommercial grades of butane and pentane today. The sulfur and benzene specifications are still needed to ensure that certified butane and certified pentane blenders do not increase the amount of sulfur and benzene in the national gasoline pool.

Under part 80, commercial grade pentane is subject to both 95 volume percent pentane purity specification and a maximum 5 volume percent C6 [40] and higher carbon number hydrocarbons specification.[41] Non-commercial grade pentane is subject to 95 volume percent pentane purity specification but is not subject to specifications on the amount of C6 and higher carbon number hydrocarbons that may be present. We are proposing to not include a standard on C6 and higher hydrocarbon content in part 1090 for certified pentane given that compliance with the proposed 95 volume percent pentane purity specification would ensure that no more than 5 volume percent C6 and higher hydrocarbons are present.

Unlike the current standard for non-commercial grade pentane, the current standards for commercial and non-commercial grade butane do not include a specification on minimum butane purity. With the proposed removal of the maximum olefin and aromatics specifications for certified butane, it is appropriate to propose controls on the purity of certified butane that are consistent with the purity specification for certified pentane. During the rule development process, we requested input from industry on applying a 95 volume percent purity specification to certified butane similar to the proposed purity specification for certified pentane. Butane blenders stated that implementing a minimum 95 percent purity specification would cause unnecessary additional processing costs to remove pentane that is often present. They noted that the presence of pentane would not be an environmental concern because of the clean burning properties of pentane and the lower volatility of pentane compare to butane. Butane blenders suggested that implementing a minimum 92 volume percent purity specification for certified butane would accomplish our intended goal of ensuring that undesirable chemical species do not contaminate certified butane while providing the necessary flexibility. We agree that a 92 volume percent purity specification would not result in increased emissions from the use of certified butane compared to a 95 volume percent purity specification and would reduce the burden to industry; therefore, we are proposing a minimum 92 volume percent purity specification for certified butane. We request comment on whether the proposed 92 volume percent purity specification for certified butane would provide sufficient flexibility to allow for the presence of pentane in certified butane while still preserving gasoline quality or whether a more or less stringent purity specification would be appropriate.

We are also proposing to simplify the quality assurance requirements for certified butane and pentane blenders. Under part 80, butane and pentane blenders are required to conduct periodic quality assurance testing of the batches of butane or pentane they receive. For butane, the current frequency of sampling and testing for the butane received from each butane supplier must be one sample for every 500,000 gallons of butane received, or one sample every three months, whichever is more frequent. For commercial-grade pentane, the sampling and testing frequency is once for every 350,000 gallons of pentane, or one sample every three months, whichever is more frequent. Noncommercial-grade pentane is currently subject to a more frequent sampling and testing frequency of once every 250,000 gallons or one sample every three months, whichever is more frequent.

To simplify these quality assurance requirements, we are proposing to require the same sampling and testing frequency for certified butane and pentane of once every 500,000 gallons of butane or pentane received, or one sample every three months, whichever is more frequent. We believe that a more frequent sampling and testing is not needed for certified pentane versus certified butane given that they are subject to similar standards. To the extent that there may be heightened concern with the potential presence of high boiling range hydrocarbons that are typically only found in full boiling range gasoline (such as C7-C20 hydrocarbons) in certified pentane versus certified butane due to difference in manufacturing processes,[42] we believe that such concerns are adequately mitigated by the existing registration requirements for certified pentane producers.

4. State and Local Fuel Standards

a. Overview

We are transferring and consolidating the part 80 regulations that relate to RVP, RFG, and other summer gasoline requirements to part 1090. For example, we are removing outdated provisions and making it easier to identify the RVP standard that applies in a given location. We are also proposing changes that are intended to update and simplify existing regulations and reflect our experience in implementing these provisions in partnership with states and industry. For example, we are proposing procedures for states that request a relaxation of the federal RVP limit of 7.8 psi. This is similar to the existing procedures used for RFG opt-out by states. We are not proposing any regulatory revisions for current fuel programs that apply in several states. The following sections detail the changes we are proposing.

We are also using this action to announce that an updated boutique fuel list is currently posted on our website.[43] Section 1541(b) of EPAct requires EPA to remove any fuel from the published list if the fuel either ceases to be included in a state implementation plan (SIP) or is identical to a federal fuel.[44] Several fuels have ceased to be included in SIPs since the boutique fuel list was originally published in 2006.[45] The boutique fuel list on our website, however, provides up-to-date information on where such fuels are currently used.

b. Consolidating Gasoline Volatility Standards

We are transferring summer gasoline requirements related to RVP limits that are currently in part 80 to part 1090. Summer gasoline for use in the continental U.S. must comply with either the federal maximum RVP limit of 9.0 psi or the more stringent RVP limit of 7.8 psi, unless it is either a federal RFG covered area, is subject to California's RFG regulations, or EPA has waived preemption and approved a state request to adopt a more stringent RVP into a SIP.[46 47 48] The proposed regulatory text would simplify and clarify regulatory text currently in 40 CFR 80.27(a) and 80.70, and would not change the current federal RFG and summer gasoline RVP requirements nationwide.

c. Reformatting the List of Areas Where Federal Low RVP Standard Applies

We are also transferring the current RVP standards in 40 CFR 80.27(a)(2), which sets out the current federal RVP limits to part 1090. Areas subject to the federal 7.8 psi RVP limit are listed in a table in 40 CFR 1090.215(a)(1), describing the geographic areas subject to the 7.8 psi RVP limit. The regulatory text specifies that any gasoline that is not subject to a lower RVP limit is subject to the federal 9.0 psi RVP limit. We are not proposing any changes or revisions to applicable RVP limits. Specifically, we are:

  • Removing the regulatory text in 40 CFR 80.27(a)(1) because it is outdated and has not applied since 1991.
  • Replacing the regulatory text, table, and footnotes that are currently in 40 CFR 80.27(a)(2) with a reformatted table in part 1090 that lists the areas where the federal 7.8 psi RVP limit for summer gasoline currently applies.

The table in 40 CFR 1090.215(a)(1) includes the name of the area and the county or counties in the area where the federal 7.8 psi RVP limit applies, rather than the current table in part 80 that dates back to the initial one-hour ozone standard, is overly complex and has caused confusion among states and industry. The new table would also include a description of the boundaries for areas that include partial counties where RVP standards are currently in effect. Under the current regulations in part 80, interested parties must search 40 CFR part 81 in order to identify these specific boundaries of the area where the 7.8 psi RVP limit applies. As previously noted, this action does not change any existing requirements.

d. Reformatting Federal RFG Applicability and Covered Areas

As part of transferring part 80 requirements relating to federal RFG to part 1090, we are reformatting how the information on current RFG covered areas is presented. Specifically, in 40 CFR 1090.270 we are presenting the description of RFG covered areas in a table format and grouping the covered areas by the process under which the area became a covered area. There are four ways in which an area could have become an RFG covered area:

  • It was included in the original RFG covered areas under CAA section 211(k)(10)(D) because its 1987-1989 ozone design value was among the nine highest design values and its 1980 population was greater than 250,000;
  • It was subsequently reclassified to Severe for an ozone NAAQS;
  • It was a classified ozone nonattainment area that opted into the RFG program; or
  • It was an attainment area in the ozone transport region that opted into the RFG program.

The tables in part 1090 list the areas in each of these groups. As previously explained, we are not changing the geographic applicability of federal RFG.

We are also transferring the existing regulatory processes by which an area may become a federal RFG covered area in the future, which are if: (1) An area is reclassified to Severe nonattainment for an ozone NAAQS; (2) a governor requests that a classified ozone nonattainment area become a covered area; or (3) a governor requests that an attainment area in the ozone transport region be included as a federal RFG covered area.

We are also including two California areas on the list of covered areas in part 1090 because the areas became federal RFG covered areas when they were reclassified as Severe ozone nonattainment areas.[49] The two areas are the Sacramento Metro area and the San Joaquin Valley area.[50] We have provided information on these RFG covered areas on our website but had not previously included them in the list of covered areas in 40 CFR 80.70. This does not impact California's regulations that require the sale of California RFG in these areas, but should California's regulations no longer apply in the future, the federal RFG regulations would still apply in keeping with the CAA.

e. Continuation of Federal RFG Requirements in Covered Areas When Revised Ozone NAAQS Are Implemented

In the Phase 2 Implementation Rule for the 1997 Ozone NAAQS, we stated that areas that became RFG covered areas pursuant to CAA section 211(k)(10)(D) would remain RFG covered areas at least until they were redesignated to attainment for the 1997 ozone NAAQS. We also stated that areas that became covered areas because they opted into RFG would remain covered areas until they opt out of RFG pursuant to our opt-out regulations. We also included regulatory text in 40 CFR 80.70(m),[51] parts of which are now outdated and unnecessary because they were specific to the transition from the 1-hour ozone NAAQS to the 1997 ozone NAAQS and to redesignations to attainment for the 1-hour ozone NAAQS. Both the 1-hour and 1997 ozone NAAQS have been revoked.

We are maintaining and clarifying in this action our intention and existing practice with regard to applicable RFG requirements for the implementation of revised ozone NAAQS. Our intention is consistent with our past approach and fuel program implementation to date. Specifically, for purposes of implementing revised ozone NAAQS, RFG will continue to apply in all covered areas (i.e., both areas that opted into RFG under CAA section 211(k)(6) and covered areas under CAA section 211(k)(10)(D)). As previously explained, this is consistent with how the federal RFG program has been implemented during the transition to the 1997, 2008, and 2015 ozone NAAQS. As also previously explained, part 1090 includes procedures for either removing a prohibition on or opting out of RFG requirements, consistent with CAA requirements; thus, states should be able to change their RFG programs under certain cases.

f. Clarifying When Mandatory RFG Covered Nonattainment Areas Can Be Removed From the List of Covered Areas

In the Phase 2 Implementation Rule for the 1997 Ozone NAAQS, we reserved for future consideration the continued applicability of RFG requirements in mandatory RFG covered areas pursuant to CAA section 211(k)(10)(D) (i.e., they were among the areas with the nine highest 1-hour ozone design values from 1987-1989 or they have been reclassified to Severe for an ozone NAAQS) in the future.[52]

We are proposing a new provision in part 1090 that would allow mandatory RFG covered area pursuant to CAA section 211(k)(10)(D) to remove the applicability of the RFG program if certain requirements are met. Under this proposed provision, a state could request the removal of its RFG program if the RFG area was either redesignated to attainment for the most stringent ozone NAAQS in effect at the time or initially designated as attainment for the most stringent ozone NAAQS in effect. For example, the 2015 ozone NAAQS of 70 ppb is currently the most stringent ozone NAAQS. Therefore, in order for a mandatory RFG area to remove its RFG program, it would have to be either redesignated to attainment for the 2015 ozone NAAQS (if had initially been designated as attainment for that NAAQS) or be initially designated as an attainment area for the 2015 ozone NAAQS. If the area is initially designated as an attainment area for the most stringent ozone NAAQS in effect, under the proposed requirement the area would have to be redesignated to attainment for the prior ozone NAAQS before the RFG program could be removed. For example, under this proposal an area would either have been designated as an attainment area for the 2015 ozone NAAQS with an approved maintenance plan for the 2008 ozone NAAQS or be redesignated to attainment for the 2015 NAAQS to be eligible for consideration for removal of the RFG program. In either case, we are proposing to require that any request to remove the federal RFG requirements must include an approved maintenance plan that demonstrates maintenance of the ozone NAAQS throughout the period of time addressed by the maintenance plan without the emission reductions from the federal RFG program. Additionally, the proposed provision would require a state to also demonstrate that the removal of the requirement for the federal RFG program would not interfere with reasonable further progress requirements or attainment or maintenance of any other NAAQS or interfere with any other CAA requirement.[53] We seek comment on this proposed requirement.

We are proposing to allow states with current mandatory RFG covered areas to remove those programs in the future when all ozone NAAQS are attained and maintained. Although the CAA requires RFG in certain ozone nonattainment areas, it is important that states can use limited resources for programs that are necessary for attainment, rather than require the implementation of RFG indefinitely simply because such a covered area had the highest ozone design values 30 years ago or were reclassified as Severe for a prior ozone NAAQS. This proposal is premised on our view that once a covered area attains the most stringent ozone NAAQS, states should be able to determine whether an emission reduction strategy should either continue or be removed.

We believe that a mandatory RFG covered area should have the ability to determine if it is necessary to continue as an RFG covered area once it has attained the most stringent ozone NAAQS that is in effect and can demonstrate maintenance of the ozone NAAQS without the emissions reductions attributable to RFG in the approved CAA section 175A maintenance plan for the area. Requiring that an area attain the most stringent ozone NAAQS and demonstrate maintenance of the ozone NAAQS without the emissions reductions from RFG provides adequate safeguards with respect to protecting air quality improvements and public health, while providing states with the flexibility to determine the best course for maintaining the ozone NAAQS.

This proposed provision is in addition to the current RFG opt-out procedures that apply to areas that opted-in to RFG under CAA section 211(k)(6)(A) or (B) unless an opt-in area under CAA section 211(k)(6)(A) has been reclassified as a Severe ozone nonattainment area. These procedures, which were established in 1996 and 1997, are currently in 40 CFR 80.72 and are also being transferred to part 1090.[54] We are not changing them except for removing obsolete regulatory text and minor clarifications, such as requirements that applied for specific periods of time that are now in the past.

g. Providing Streamlined Procedures for Areas Relaxing the Federal Low RVP Standard

We are proposing to include a new streamlined process for state requests to relax the federal 7.8 psi RVP standard for gasoline sold between June 1st and September 15th of each year. This action would provide procedures similar to those that are currently used when states opt out of the RFG program.[55]

The current federal 7.8 psi RVP limit took effect in 1992 and was initially required in certain 1-hour ozone NAAQS nonattainment areas. We have also allowed for state relaxation requests and since 2014 we have approved relaxations of the federal 7.8 psi RVP standard for 12 areas in the states of Alabama, Florida, Georgia, Louisiana, North Carolina, and Tennessee.[56] As discussed in Section V.A.4.c, we are providing a new table in part 1090 that sets out where the federal 7.8 psi RVP standards currently applies.

Under our current regulations, the process for accomplishing low RVP relaxation requires two EPA approval actions before a state's request can be effective. First, the EPA Regional Office needs to approve a state's revision to an area's SIP, such as a maintenance plan, for the relevant ozone NAAQS. After that rulemaking is completed, a second rulemaking by EPA Headquarters is necessary to remove the subject area(s) from the federal low RVP regulations in 40 CFR 80.27(a)(2).[57] The current process of requiring both of these approval actions before a state's request is effective is cumbersome and time consuming given the number of linear steps involved. There is also an element of confusion and uncertainty to states, local businesses, industry, and the public concerning the effective date of an RVP relaxation.

Based on our experience since 2014, we have concluded that the current RFG opt-out regulatory procedures provide a better model for considering state requests to relax the federal 7.8 psi RVP standard. Our proposed regulations for relaxing the federal 7.8 psi RVP standard in part 1090 mirrors the current part 80 RFG opt-out procedures, and are as follows:

  • The Governor of the state or his/her designee would request in writing that EPA relax the federal 7.8 psi RVP standard.
  • The state would continue to be required to revise its approved SIP for the area (e.g., the ozone maintenance plan for the area) to appropriately account for the change in emissions due to the increase in the RVP limit and to address the CAA section 110(l) non-interference requirements.
  • The EPA Regional Office would have to approve that SIP revision and CAA section 110(l) demonstration.
  • Once, the Regional Office's action is complete, we would establish an effective date for the relaxation, which would be no less than 90 days after the effective date of the Regional Office's approval. We would notify the Governor in writing, typically through a letter, of the effective date and publish a notice in the Federal Register. Gasoline meeting the 7.8 psi RVP standard would not be required to be sold after that effective date.
  • Subsequently, we would publish a separate final rule to remove the area from the list of areas where the 7.8 psi RVP limit continues to apply (i.e., from the list of areas in part 1090). We believe that notice-and-comment rulemaking would no longer be necessary for relaxation actions because it merely codifies a change that has been made through a process that is included in our regulations and would be merely administrative in nature.

Use of this proposed process would eliminate the need for EPA to complete a notice-and-comment rulemaking each time EPA acts on a request to relax a low volatility gasoline standard to remove the subject area from the list of areas subject to that standard. Under this proposed process, similar to the current RFG opt-out procedures, the effective date of the federal low RVP relaxation would be known shortly after the EPA Regional Office's rulemaking on the state's SIP revision becomes effective. We believe that using similar procedures for acting on state requests to change either federal low RVP or RFG programs would avoid unnecessary confusion and still continue to provide the same level of environmental protection. Under both the current regulations in part 80 and the proposed regulations in part 1090, the state's SIP revision must include revisions to the on-road and nonroad mobile source NOX and VOC inventories to reflect the removal of the federal low RVP fuel. The SIP must also demonstrate that the area would continue to maintain the relevant ozone NAAQS and that the change would not negatively impact the area's compliance with other CAA requirements.[58] Further, we would continue to act on such a SIP revision and CAA section 110(l) non-interference demonstration through notice-and-comment rulemaking. Finally, this proposed process, which streamlines the RVP relaxation program, would result in the conservation of limited government resources and bring certainty for states, the public and gasoline suppliers as to when a state's request to relax RVP would take effect.

h. Transitioning From Federal RFG or a Boutique Fuel Program to the Federal RVP Standard in Certain States

We are providing information to states that decide to either opt out of federal RFG or remove a state SIP fuel rule that regulates gasoline RVP (i.e., a boutique fuel) that the state in its SIP revision (e.g., maintenance plan revision) may request that EPA apply the 9.0 psi RVP standard rather than the federal 7.8 psi RVP standard.[59] The SIP revision will have to document that increasing the summer RVP standard to 9.0 psi will not interfere with attainment or maintenance of the relevant ozone NAAQS or with requirements for reasonable further progress, attainment, or maintenance of any other NAAQS.[60] This reflects our experience in working with states that have decided to change their fuel programs in areas where the federal 9.0 psi RVP standard could be applied.

In such cases, the ultimate goal of these states has been to allow the sale of gasoline that meets the federal 9.0 psi RVP standard. States have previously accomplished this goal by first submitting a SIP revision (e.g., a maintenance plan revision) based on the application of the federal 7.8 psi standard and then later submitting a second SIP revision to initiate the process to relax the federal 7.8 psi RVP standard to 9.0 psi. We are providing this information to ensure that the relevant states are aware that they can accomplish the goal of relaxing the federal RVP standard to 9.0 psi as long as the associated SIP revision meet the CAA section 110(l) non-interference requirements for the relevant ozone NAAQS and all other pollutants. Accomplishing the goal of allowing the sale of gasoline that meets the federal 9.0 psi RVP standard with one SIP revision, EPA approval of one SIP revision, and one EPA action to update the lists areas subject to the specific gasoline standards will conserve state and federal resources.

This proposal allowing the transition to the federal RVP standard of 9.0 psi through one SIP revision continues to protect air quality and public health because the state must demonstrate through its SIP revision and CAA section 110(l) non-interference demonstration that air quality goals are met as required by the CAA when gasoline that complies with the federal RVP standard of 9.0 psi is sold in the area. In addition, EPA must then approve that SIP revision and CAA section 110(l) demonstration through notice-and-comment rulemaking. This approach also provides fuel suppliers with certainty and stability. Under part 1090, fuel suppliers in such areas would not be required to switch from supplying federal RFG or a state fuel to federal 7.8 psi RVP gasoline for a short period of time only to ultimately switch to supplying gasoline that meets the federal 9.0 psi RVP standard.

We note, however, that if such a state wants EPA to apply the federal 7.8 psi RVP limit, that state could document this intention in its SIP revision, and the associated emissions modeling should be based on application of the federal 7.8 psi RVP limit. In such a case, EPA Headquarters would also complete a rulemaking to revise the list of areas where the federal 7.8 psi RVP standard applies (i.e., add such an area to the list in part 1090).

i. Announcing Updates to the Boutique Fuels List

We are also using this action to announce that an updated boutique fuel list is currently posted on our website. Section 1541(b) of EPAct required EPA, in consultation with the Department of Energy (DOE), to determine the total number of fuels approved into all SIPs as of September 1, 2004, under section 211(c)(4)(C), and publish a list of such fuels, including the state and Petroleum Administration for Defense District (PADD) in which they are used for public review and comment. EPA originally published the required list on 2006.[61]

Additionally, we are required to remove any fuels from the published list if the fuel either ceases to be included in a SIP or is identical to a federal fuel.[62] Since the original list was published, a number of fuels have been removed from approved SIPs and have thus ceased to exist in SIPs.[63] In Table V.5.h-1 we are providing an updated list of boutique fuels that includes all of the boutique fuels that are currently in approved SIPs. We also maintain a current list of boutique fuels on our State Fuels website.[64] We will continue to update that website as changes to boutique fuels occur and periodically announce updates in the Federal Register for fuels that are either removed or added.

5. Substantially Similar

CAA section 211(f)(1)(B) prohibits the introduction into commerce of “any fuel or fuel additive for use by any person in motor vehicles manufactured after model year 1974 which is not substantially similar to any fuel or fuel additive utilized in the certification of any model year 1975, or subsequent model year vehicle, or engine.” While this provision has always applied to fuel and fuel additive manufacturers by virtue of it being a statutory requirement, we did not listed it in our part 80 regulations among the requirements for fuel.[67] We are proposing to address the substantially similar requirements of the CAA in part 1090 for gasoline and gasoline fuel additives as part of our effort to consolidate fuels compliance requirements and make it easier for regulated parties to understand their obligations.[68] We are proposing to include a requirement in the regulation that that all gasoline, BOBs, and gasoline fuel additives must be substantially similar under CAA section 211(f)(1)(B) or have a waiver under CAA section 211(f)(4). We seek comment on this approach.

EPA has issued two coexisting definitions of substantially similar for gasoline, one in 2008 [69] and one in 2019,[70] and several CAA section 211(f)(4) waivers. The regulations proposed today refer to the statutory provisions (CAA section 211(f)(1)(B) and (4)), and the conditions associated with CAA section 211(f)(4) waivers and the parameters associated with the 2019 definition of substantially similar.

B. Diesel Fuel

1. Overview and Streamlining of Diesel Fuel Program

Similar to our approach for the gasoline standards, we are proposing to consolidate the diesel fuel standards into a single subpart in part 1090 (subpart D). We are not proposing any changes to the sulfur or cetane/aromatics standards for diesel fuel, the sulfur standards for diesel fuel additives, or the ECA marine fuel standards. We are removing expired provisions that were needed to support the phase-in of the diesel fuel sulfur program. The phase-in period was completed in 2014; however, these now expired phase-in provisions are imbedded throughout the diesel program regulations, adding burden to regulated parties in identifying their compliance duties and confusing other stakeholders. As part of the transfer of current part 80 regulations to part 1090, we are also consolidating identical provisions for highway and other diesel fuels into a single regulatory requirement to improve clarity.

We are proposing the following revisions to existing part 80 regulations in the following sections. First, we are proposing to remove the requirement that motor vehicle diesel fuel be free of red dye because we believe this requirement no longer provides an effective means of evaluating compliance with the diesel sulfur standards. Second, we are proposing to streamline the requirements that pertain to importation of diesel fuel that does not meet EPA standards. Third, we are proposing to remove the registration requirement for ECA marine fuel distributors and associated requirements to include a registration number on PTDs. Finally, we are proposing streamlined means for downstream parties to redesignate heating oil, kerosene, and jet fuel as ULSD that would require specific documentation from the original fuel manufacturer.

We expect that these proposed changes, when finalized, would simplify the diesel fuel programs, resulting in reduced burden associated with demonstrating compliance with the applicable sulfur standards and maximize the fungibility of diesel fuel, allowing the market to operate more efficiently. These changes are not expected to change the stringency of the diesel fuel and IMO marine fuel standards.

2. Removing the Red Dye Requirement

Part 80 currently requires that motor vehicle diesel fuel must be free of visible evidence of dye solvent red 164 (which has a characteristic red color in diesel fuel), except for motor vehicle diesel fuel that is used in a manner that is tax exempt under section 4082 of the Internal Revenue Code.[71] This EPA requirement is consistent with a parallel requirement in the Internal Revenue Code that is intended to support compliance with diesel fuel tax requirements. Under the Internal Revenue Code, NRLM diesel fuel, heating oil, and exempt highway diesel fuel [72] must contain red dye before leaving a fuel distribution terminal to indicate its tax-exempt status.

When the sulfur standards for off-highway diesel fuel were less stringent than those for motor vehicle diesel fuel, the presence of red dye was a useful screening tool for EPA to identify potential noncompliance with the sulfur standards for highway diesel fuel. However, the presence of red dye has become a much less useful indicator of sulfur noncompliance as other distillate fuels have become subject to the same 15 ppm sulfur standard that applies to highway diesel fuel. With the completion of the phase-in of our diesel fuel sulfur program in 2014, all highway, nonroad, locomotive, and marine diesel fuel must meet a 15 ppm sulfur standard except for a limited volume of locomotive and marine (LM) diesel fuel produced by transmix processors, which is subject to a 500 ppm sulfur standard. The distribution of 500 ppm LM diesel fuel is subject to separate compliance provisions to ensure that is not misdirected for use in highway, nonroad, locomotive, or marine engines that require the use of 15 ppm diesel fuel (ULSD).

The other potential source of red-dyed high-sulfur diesel fuel that might inappropriately be diverted as highway diesel has been heating oil. However, the vast majority of heating is currently subject to a 15 ppm standard.[73] Therefore, we believe that the requirement that red dye should not be present in motor vehicle diesel fuel no longer provides meaningful added assurance of compliance with highway diesel ULSD standards. Rather, the existence of this requirement complicates the process of providing alternate sources of diesel fuel when supplies of highway diesel fuel are constricted due to extreme and unusual supply circumstances. State authorities are currently required to request a waiver from EPA and the Internal Revenue Service (IRS) from the respective agency's red dye requirements to enable the use of 15 ppm NRLM diesel fuel on highway during such circumstances. Eliminating our red dye requirement would reduce state officials' waiver requests to just an IRS waiver during such events without substantially affecting the ability of EPA to enforce highway ULSD standards. Therefore, we are proposing to remove the EPA requirement that motor vehicle diesel fuel must be free from visual evidence of red dye.[74] This proposed change would not alter the Internal Revenue Code requirement that NRLM diesel fuel, heating oil, and exempt motor vehicle diesel fuel must contain red dye before leaving a fuel distribution terminal to indicate its tax-exempt status.

3. Importation of Off Spec Diesel Fuel

We are proposing to replace the provisions for the importation of diesel fuel treated as blendstock (DTAB) [75] with a streamlined procedure to handle imported off-spec diesel fuel. Under part 80, most of the DTAB provisions are designed to account for the DTAB in compliance calculations that have not been used since 2010. The part 80 provisions require importers to include DTAB in compliance calculations that are no longer applicable, to keep DTAB segregated from other diesel fuel, and limit the importer's ability to transfer title of DTAB. Under part 1090, importers could import diesel fuel that does not comply with EPA standards if certain provisions (which are a subset of those currently required under part 80) are met. Under the proposed provisions, the importer would be required to offload the imported diesel fuel into one or more shore tanks containing diesel, sample and test the blended fuel to confirm that it meets all applicable per-gallon standards before introduction into commerce, and keep all applicable records. We believe that this simplification provides the needed flexibility for importers while providing improved clarity.

4. Annex VI Marine Fuel Standards

In this action, we are mostly proposing to transpose without change the regulations in subpart I of part 80 for distillate diesel fuel that complies with the 0.10 percent (1,000 ppm) and 0.50 percent (5,000 ppm) sulfur standards contained in Annex VI to the International Convention for the Prevention of Pollution from Ships (MARPOL Annex VI). The U.S. ratified MARPOL Annex VI and became a Party to this Protocol on October 8, 2009. MARPOL Annex VI requires marine vessels operating globally to use fuel that meets the 0.50 percent sulfur standard starting January 1, 2020, rather than the current standard of 3.50 percent (35,000 ppm) sulfur (“global marine fuel”). The MARPOL Annex VI standard is 0.10 percent sulfur for fuel used in vessels operating in designated Emission Control Areas (ECAs).[76]

In a separate action, we modified our diesel fuel regulations in part 80 to allow fuel manufacturers and distributors to sell distillate diesel fuel meeting the 2020 global marine fuel standard instead of the ULSD or ECA marine standards.[77] We are incorporating those provisions into part 1090 with minor changes to be consistent with the proposed part 1090 structure.

Regarding ECA marine fuel, we are including the provisions from part 80 in part 1090 without change save one major exception. Under part 80, distributors of ECA marine fuel from the refiner to the point of transfer to a vessel are currently required to register with EPA and must include this registration number on PTDs.[78] Distributors of other distillate and residual fuels had similar “designate and track” requirements during the phase-in of the ULSD standards for highway and nonroad diesel fuel to allow the temporary use of limited volumes of 500 ppm highway and nonroad diesel fuel under the program's small refiner and credit provisions.[79] The majority of these requirements gradually expired with the phase-out of the ULSD program's small refiner and credit provisions that ended in 2014, which allowed the production of limited volumes of 500 ppm highway diesel fuel. Beginning in 2014, the only fuel distributors that must register with EPA are those that handle ECA marine fuel and 500 ppm LM diesel fuel produced by transmix processors.[80]

We believe that the benefit associated with having ECA marine fuel distributors register with EPA may not outweigh the burdens associated with this requirement. Like distributors of other regulated fuels, distributors of ECA marine fuel would be required to identify themselves on the PTD. This information could be used by EPA to help determine what parties in the ECA marine fuel distribution chain may be responsible for fuel represented as ECA marine fuel in the distribution system that does not meet the requisite fuel quality standards. While having a registration number on the ECA marine fuel PTD facilitates this process, we do not believe that it is necessary. Therefore, we are proposing to remove the requirement that distributors of ECA marine fuel must register with EPA and include this registration number on ECA marine fuel PTDs. We believe that this would meaningfully reduce the burden to fuel distributors and would avoid potential delays in the transportation of ECA marine fuel due to potential distributors not being registered with EPA, while not diminishing the air quality benefits of the ECA marine fuel program. Any person who produces diesel fuel, including ECA marine fuel, by mixing blendstocks is a blender manufacturer and must continue to register and comply with all applicable requirements; this is consistent with the current regulatory under part 80 and would be unchanged in part 1090. We request comment on the benefits and costs of the current registration requirement for ECA marine fuel distributors.

5. Heating Oil, Kerosene, and Jet Fuel

Under part 80, we first established the diesel sulfur program that required only on-highway or motor vehicle diesel to meet the 15 ppm sulfur standard. We designed most of the provisions related to designating, segregating, and labeling distillate fuels to avoid the contamination of ULSD with higher sulfur distillate fuels, which at the time were non-road diesel, heating oil, kerosene, and jet fuel. Now a federal 15 ppm standard applies for motor vehicle, non-road, locomotive, and marine diesel fuel, and, as discussed in Section V.B.2, a state or local 15 ppm sulfur standard applies to most of the heating oil used in the U.S. The provisions designed to avoid contamination of ULSD with higher sulfur distillate fuels now exist where there is no difference between most distillate fuels; however, the provisions have remained in place despite this change in the distillate fuel market. These obsolete provisions contribute to inefficiency in the distribution system leading to higher costs, and barriers to the free movement of fuel during times of unforeseen supply disruptions (e.g., refinery fires, hurricanes, etc.). Therefore, we are proposing to allow heating oil, kerosene, and jet fuel certified to ULSD standards to be redesignated downstream as ULSD for use in motor vehicles and NRLM engines without recertification by the downstream party if certain conditions are met.

Under these proposed provisions, downstream parties could rely upon documentation from pipelines or fuel manufacturers that the heating oil, kerosene, or jet fuel was certified to meet the 15 ppm ULSD sulfur standard and cetane/aromatics specifications to fungibly transport, store, and dispense all 15 ppm sulfur distillate fuels downstream. We are also proposing provisions in part 1090 that would also allow ULSD to be used as heating oil, kerosene, jet fuel, or ECA marine fuel without recertification as long as records are kept demonstrating that the ULSD had been redesignated. We believe that these provisions would maximize the fungibility of distillate fuels, resulting in substantially reduced distributional costs and greater efficiency in the fuels market.

During the rule development process, several stakeholders asked that we address issues regarding accounting for distillate fuels under the RFS program. We believe that this is outside the scope of this action. We recognize that this proposal could impact RFS compliance and have finalized provisions to help clarify how obligated parties (i.e., refiners and importers of gasoline and diesel fuel) account for distillate fuels under the RFS program in a separate action.[81]

We believe these proposed changes could help increase the efficiency with which distillate fuels are distributed, resulting in significant cost savings to stakeholders and consumers. We seek comment on whether this is the case and on how to quantify the associated cost savings.

VI. Exemptions, Hardships, and Special Provisions

A. Exemptions

We are also transferring provisions that exempt fuels from applicable standards that are currently contained in part 80 to part 1090. We are proposing minor revisions for purposes of modernizing these exemptions as well as removing obsolete exemption provisions, and any exemptions that were granted under part 80 will remain in effect with their original conditions as applicable under part 1090. As a result, instead of being scattered through various subparts as is the current practice in part 80, these provisions would be consolidated into a single subpart in part 1090 (subpart G) for all exemptions. This includes those exemptions that require a petition such as the hardship exemption and those that do not such as the for export exemption. This structure is designed to increase their accessibility and usability. Consistent with current provisions, exempted fuels, fuel additives, and regulated blendstocks do not need to comply with the standards of part 1090, but remain subject to other requirements (e.g., registration, reporting, and recordkeeping) that are now also proposed to be moved to part 1090.

We are not proposing any revisions to exemptions nor the related requirements that apply to fuels used for national security and military purposes, temporary research and development (R&D), racing, and aviation. Similarly, we are not proposing to change the exemption that applies to fuel in Guam, American Samoa, and the Commonwealth of the Northern Mariana Islands. Summer gasoline in Alaska, Hawaii, Puerto Rico, and the U.S. Virgin Islands would also continue to be exempt from the federal volatility regulations.

We are, however, proposing minor revisions to these exemptions for consistency and as a result of consolidating the various part 80 exemptions. We are proposing that exemptions granted under part 80 would remain in effect under part 1090, and as previously explained removing exemption provisions that are no longer active.

We are proposing some changes to modernize the exemption provisions. First, we are proposing to include language that would impose conditions on parties operating under a research and development (“R&D”) test program to prevent the inadvertent use of test fuels exempted under a temporary R&D exemption by participants not included in the test program. Recently, we have received requests for R&D exemptions that focus on the effects of a certain fuel's use in more real world operation conditions (as opposed to a contained laboratory type situation). This often requires the test fuel be made available in a way that could result in vehicles or engines not included as part of the R&D program inappropriately using the test fuel. We believe it is appropriate for applicants requesting such an R&D exemption to take reasonable precautions to prevent consumers not participating in the test program from fueling with the test fuel. We are requesting comment on procedures that could be applied to fuels being tested under an R&D exemption when the test includes consumer participation that could result in the aforementioned misfueling.

Second, we are proposing to allow certain exemptions for fuel additives and regulated blendstocks. Under part 80, it was unclear whether some exemptions applied to fuel additives and regulated blendstocks under certain programs, such as the gasoline sulfur program. Under 1090, fuel additives and regulated blendstocks would now be exempt from applicable requirements if certain conditions are met. For example, the military use exemption would now explicitly exempt fuels, fuel additives and regulated blendstocks used in either military vehicles or in support of military operations.

Third, we are proposing that parties that transport and store exempt aviation and racing fuel take reasonable precautions to avoid the contamination of exempt fuels when using the same tanker trucks and tanks to transport and store exempt and non-exempt fuels. Aviation and racing gasoline can often contain lead additives that can harm emission controls on vehicles and engines designed to operate on unleaded gasoline. For example, when a tanker truck carrying exempt racing gasoline is later used to transport non-exempt gasoline, residual exempt racing gasoline could remain in the tanker truck and contaminate the non-exempt gasoline. We believe it is prudent for parties to follow established voluntary consensus-based standards for the cleaning out of tanker trucks. As such, part 1090 lists two such examples for cleaning tanker trucks to avoid contamination.[82] We seek comment on this proposed requirement and whether there are other voluntary consensus-based standards we should reference.

California gasoline and diesel fuel are currently exempt from the part 80 standards in separate provisions under the various subparts. We are consolidating these existing exemptions for California fuels into a single comprehensive section. This reorganization eliminates the redundancy that resulted as new programs were implemented with California exemptions and old programs sunset but remained in the regulations with their original California fuels exemption. Additionally, housing all the provisions for the California fuels exemption in one section facilitates compliance with its requirements, as regulated parties need not scour part 1090 for hidden exemption provisions. We are also proposing provisions that clarify how California gasoline and diesel fuels may be used in states other than California in the consolidated California exemption section that explains the provisions. Under the current part 80 regulations, fuel manufacturers that make California gasoline and California diesel fuel must recertify those fuels in order to sell them outside the state of California. We are retaining this recertification requirement in part 1090. Fuel manufacturers of California gasoline may recertify their fuels under the applicable standards of this part in order to sell such gasoline outside California. When manufacturers of California gasoline recertify their gasoline, they may participate in the Federal Averaging, Banking, and Trading (“ABT”) programs for gasoline sulfur and benzene. In addition to maintaining the option of recertifying, we are proposing to allow California gasoline manufacturers or distributors of California gasoline to simply redesignate the fuel as CG or RFG, so long as the California gasoline meets all the requirements for California reformulated gasoline under Title 13 of the California Code of Regulations and the manufacturer or distributor meets applicable designation and recordkeeping requirements.[83] Under this proposal, parties that redesignate California gasoline for use outside of California would not be permitted to generate sulfur or benzene credits from the redesignated fuel. Similarly, California diesel fuel used outside of California would be deemed in compliance with the standards of this part if it meets all the requirements Title 13 of the California Code of Regulations and the manufacturer or distributor meets applicable designation and recordkeeping requirements.[84]

B. Exports

We are transferring the current part 80 exemption from applicable standards for fuels, fuel additives, and regulated blendstocks that are designated for export to part 1090. Additionally, we are transferring requirements for designation, product transfer documents, and gasoline segregation for fuels designated for export that currently apply under part 80 to part 1090. Diesel fuels not designated for export could be exported without restriction as long as those fuels meet the applicable fuel quality standards. However, the fuel remains subject to the provisions of this part while in the U.S. For example, fuel designated as ULSD must meet the applicable sulfur standards even if it will later be exported. Such diesel fuel that meets ULSD standards would not need to be segregated and may be redesignated for export by a distributor. On the other hand, diesel fuel that does not meet the ULSD standards would need to be designated for export and segregated from the point of production until the diesel fuel was exported, as currently required under part 80. We are also not proposing to require segregation of fuel additives and regulated blendstocks designated for export. However, some regulated parties have suggested applying the segregation requirement to those products, and we are seeking comment on whether to impose such a requirement as well as the impacts of imposing such a requirement.

Under part 80, gasoline manufacturers are required to segregate gasoline designated for export. In this action, we are not proposing to change this segregation requirement for gasoline exports. The only modification from part 80 is that these provisions, instead of being included in each gasoline program subpart, will be consolidated into a single subpart for exports under part 1090.

C. Hardships

Under part 80, various subparts include separate provisions for receiving an exemption from that subpart's fuel quality standards due to unforeseeable hardship. We are proposing to consolidate these exemptions into one general hardship provision for unforeseeable circumstances (e.g., a natural disaster or refinery fire) that a refinery cannot avoid with prudent planning (excluding financial and supply chain hardship). The proposed reorganization is intended to make the hardship provision easier to find and does not change either the opportunity for a hardship or the regulated party's burden to demonstrate that its circumstances satisfy the requirements for applicable hardship exemptions. This change would not affect the RFS program, however, given that we are retaining the program in part 80. Accordingly, any exemptions available under that program would similarly remain unaffected.

VII. Averaging, Banking, and Trading Provisions

A. Overview

We are transferring the part 80 averaging, banking, and trading (ABT) provisions for compliance with the sulfur and benzene average standards for gasoline to part 1090.[85] We are proposing modifications that will facilitate consolidation of these various ABT regulatory provisions in part 80 into a single set of ABT provisions in part 1090. We are not transferring part 80 regulations that established separate ABT provisions for small refiners and small volume refineries given that they expired at the end of 2019. We have used ABT provisions to as a means to both meet our environmental objectives and provide regulated parties with the ability to comply with our fuel standards in the most efficient and lowest cost manner. This section also includes changes to how gasoline manufacturers could account for oxygenate added to gasoline downstream of fuel manufacturing facilities in compliance calculations. This section further describes a new proposed mechanism that would allow downstream parties that recertify batches of gasoline to use different types and amounts of oxygenate downstream of a manufacturing facility.

B. Compliance on Average

We are proposing some minor changes to the format of the average compliance calculations to align the sulfur and benzene compliance calculations more closely to accommodate consolidating annual compliance reporting into a single reporting format. Under part 80, compliance with the benzene and sulfur average standards is demonstrated in separate forms and use a slightly different nomenclature. The proposed changes to the compliance calculations would not affect how gasoline manufacturers currently comply with the average standards or their stringency; however, the proposed equations appear slightly different compared to the similar equations in part 80. We are also proposing to add deficits incurred on an annual basis due to the recertification of BOBs downstream to use different types and amounts of oxygenates. This proposed change is discussed in detail in section VII.G.

As previously noted, all part 80 regulations that had separate ABT provisions for small refiners and small volume refineries have expired or will by the time this proposed rule is implemented. The last such provisions are those related to the Tier 3 gasoline sulfur program, which will expire on December 31, 2019, resulting in small refiners and small volume refineries being required to be in compliance with the same part 80 fuel quality standards as other refiners. Since the proposed streamlined fuel quality regulations would take effect January 1, 2021, part 1090 does not include separate ABT provisions for small refiners and small volume refineries. If in the future we propose new fuel standards, we would likely consider flexibilities for small refiners and small volume refineries as part of that future action.

C. Deficit Carryforward

Under the Tier 3 sulfur and MSAT2 gasoline programs, we allow gasoline manufacturers to carryforward deficits, whereby an individual fuel manufacturing facility that does not meet either the sulfur or benzene standard in each compliance period may carry a credit deficit forward into the next compliance period. Under this deficit carryforward allowance, the manufacturer for the facility must make up the credit deficit and come into compliance with the applicable standard(s) in the next compliance period. We are proposing to consolidate the deficit carryforward provisions and we have proposed language that differs from the part 80 deficit carryforward provisions because the proposed language accommodates the consolidation of the gasoline sulfur and benzene deficit carryforward provisions into a single carryforward provision.

D. Credit Generation, Use, and Transfer

We are also transferring the part 80 credit generation, use, and transfer provisions for gasoline manufacturers to part 1090. We are proposing minor changes to the language largely to ensure consistency between the sulfur and benzene credit trading programs.

We are not proposing any changes to the lifespan of generated credits (i.e., credits generated under part 1090 would have the same lifespan as afforded them under part 80). Additionally, credits generated under part 80 would still be usable to comply with average standards under part 1090. To facilitate the use of part 80 credits under part 1090, we are including language to make it clear that credits generated under part 80 would still be valid for compliance under part 1090 for the specified life of the credits under part 80. For example, for credits generated for the 2020 compliance period, gasoline manufacturers could use those credits through the 2025 compliance period.

E. Invalid Credits

We are transferring the part 80 provisions for treatment of invalid credits to part 1090 without any modifications. Since the establishment of the sulfur and benzene ABT programs, we migrated tracking of credit transactions into EMTS. During the rule development process, we received feedback from stakeholders suggesting that the process for remediating invalid credits was onerous due to the administrative process associated with modifying credits in EMTS. Stakeholders also suggested that we rearrange the compliance deadlines to have annual compliance reports due after annual audits have occurred. Some stakeholders suggested that since the annual audit process identifies several issues after annual compliance reports have been submitted (i.e., after credits have been traded and retired for compliance), this switch would then allow for fewer resubmissions of reports and fewer remedial actions for invalid credits. Responsible parties would not need to amend reports since they would have been able to correct the original compliance reports based on an audit. We are not proposing to change the compliance deadlines. We believe changing the compliance deadlines would disrupt a relatively well functioning compliance program and we believe other actions proposed as part of the streamlined fuel quality regulations would reduce the frequency of resubmissions and remedial actions. For example, we believe by allowing less precision in the rounding of gallons, responsible parties would have fewer remedial actions if audits identify that a party was off by a single gallon on their annual reports. We also believe that by streamlining the regulatory and reporting requirements, compliance demonstrations would be less prone to the types of errors that often require resubmissions. We also note that companies always have the option of performing their own audits internally. However, we seek comment on whether we should rearrange the compliance deadlines as a means to reduce resubmissions and remedial actions.

F. Downstream Oxygenate Accounting

We are proposing a single method for gasoline manufacturers to account for oxygenate added downstream of a fuel manufacturing facility. Oxygenate accounting provides the flexibility for fuel manufacturers to ensure that average standards are met. Under part 80, we have provided several mechanisms, depending on the gasoline program, for refiners and importers to account for oxygenate added downstream. Under the current part 80 RFG provisions for oxygenate blending and accounting, refiners and importers create a hand blend and test the hand blend for reported parameters and include these values in their compliance calculations to demonstrate compliance with sulfur and benzene average standards and the RFG performance standards. The refiner or importer then specifies the type(s) and amount(s) of oxygenates on PTDs to be added by the oxygenate blender, who must then follow the blending instructions by the refiner or importer. Further, refiners and importers must contract with an independent surveyor to verify that an oxygenate is added downstream at levels reported to EPA in batch reports.

Due to the fungible nature of most CG and CBOB, it is difficult for many CG/CBOB refiners or importers to account for oxygenate that is added downstream. Under part 80, CG/CBOB refiners and importers can only account for oxygenate if the refiner or importer can establish that the oxygenate was in fact added to the CG or CBOB. The CG/CBOB refiner or importer can establish that the oxygenate was blended by either: (1) Blending the oxygenate themselves; or (2) having a contract with an oxygenate blender specifying procedures the oxygenate blender will follow to add the amount of oxygenate claimed by the CG/CBOB refiner or importer and the refiner or importer has an oversight program to ensure that the oxygenate blending takes place. Under Tier 3, CG/CBOB refiners and importers may assume 10 percent ethanol containing 5 ppm sulfur in compliance calculations to account for oxygenate added downstream. Further, part 80 does not contain any allowance provisions to assume dilution of benzene from oxygenate added downstream. Based on information gleaned during the rule development process, it appears the average sulfur levels for DFE are lower (2-3 ppm) than the assumed value of 5 ppm allowed under Tier 3. This regulatory disparate treatment of CG/CBOB compared to RFG/RBOB has created a scenario where it is more difficult for CG/CBOB refiners and importers to account for the benefits of the addition of downstream oxygenates.

In part 1090, we are proposing to require gasoline manufacturers to use “hand blends” when accounting for oxygenate added downstream. We are also proposing to require that oxygenate blenders follow instructions for the type(s) and amount(s) of oxygenated from the BOB manufacturer. The proposed requirements for gasoline manufacturers and oxygenate blenders largely mirror the requirements for oxygenate blending and accounting found in the RFG program.

The main differences between the proposed hand blend approach and the current RFG program is that the accompanying in-use survey would be national in scope (instead of just a survey of RFG areas), and the BOB manufacturer would need to participate in the proposed national sampling oversight program. The accompanying in-use survey requirements are discussed in more detail in Section X. Additionally, since we are broadening the scope of the oxygenate accounting process from RBOB to all BOB, we are also proposing that gasoline manufacturers prepare samples using the hand blend procedures in ASTM D7717 and that commercially available oxygenate (e.g., denatured fuel ethanol) be used to make hand blends. The oxygenate used should reflect the anticipated sulfur and benzene levels of the oxygenate that will ultimately be blended with the BOB. All other proposed requirements would be the same as currently specified for the RFG program.

During the rule development process, we received feedback from some stakeholders requesting that we allow multiple different options for gasoline manufacturers to account for oxygenate added downstream. These stakeholders argued that the use of assumptions in compliance calculations, as currently allowed under Tier 3 for sulfur, could be easier for some manufacturers to adopt. As discussed earlier, we currently allow for many different methods for accounting for oxygenate added downstream. While this has allowed some gasoline manufacturers (primarily manufacturers of RFG) to benefit from this ability, it has practically precluded other gasoline manufacturers (primarily manufacturers of CG) from enjoying the same flexibility, creating an unlevel playing field. We believe that providing a single method of accounting for oxygenate added downstream ensures a level playing field for all gasoline manufacturers and allows us to better assure that appropriate levels of oxygenate are accounted for through in-use verification in the downstream survey. Additionally, setting assumptions for manufacturers to use in compliance calculations would require information on what those assumptions should be for all regulated parameters (i.e., benzene, sulfur, and RVP). The validity of such assumptions could change over time as new oxygenates or, in the case of DFE, new sources of denaturant are established over time. Changing such assumptions would require EPA to amend its regulations, potentially resulting in an inadvertent change in in-use fuel quality. On the other hand, by utilizing the proposed hand blend approach, we would allow gasoline manufacturers to adjust hand blends to adapt to market changes almost immediately (e.g., if there was an increased demand for E0 or E15). This would ensure that what is reported is ultimately reflective of what is happening in the market, thereby maintaining the stringency of the fuel quality standards over time. However, we seek comment on allowing parties to use assumptions and if so, appropriate assumed values for oxygenates added downstream. In particular, we seek specific data supporting the use of assumed values.

Also, during the rule development process, some stakeholders highlighted that allowing CG manufacturers that are not currently accounting for oxygenate added downstream may result in a change in in-use fuel quality. These stakeholders pointed out that if CG manufacturers are not currently taking advantage of oxygenate accounting due to the difficultly of ensuring that oxygenate is added downstream, these manufacturers would be slightly over-complying with the required sulfur and benzene average standards. We expect any such effects to be minimal, and we discuss these potential effects in more detail in Section XIV.[86]

G. Downstream Oxygenate Recertification

Under the part 80 RFG program, oxygenate blenders must add the type(s) and amount(s) of oxygenate(s) to RBOB as specified by refiners under 40 CFR 80.69. Refiners must specify blending instructions for all RBOB, most of which is to be made into E10. An oxygenate blender that recertifies a batch of RBOB under part 80 is a gasoline refiner and must comply with all the applicable requirements for a gasoline refiner. These requirements include registration under part 79 as a fuel manufacturer, registering under part 80 as a refiner, complying with sulfur and benzene average standards, and batch sampling and testing. As a result of these requirements and the relatively low volume of E0 needed, oxygenate blenders do not typically opt to assume the role of a gasoline refiner, reducing the availability of E0 in RFG areas. Similarly, the RFG regulations under part 80 practically preclude the use of isobutanol in RBOBs since the regulations require that oxygenate blenders add the type and amount of oxygenate specified by the RFG refiner or importer (which is predominately E10). Under part 80, parties may recertify the batch of RFG; however, the high cost associated with recertifying batches of RBOB downstream essentially precludes oxygenate blenders from blending isobutanol in RFG areas since the batch sizes are relatively small (typically the volume of a single tanker truck).

These restrictions, currently limited to RFG areas, could be compounded by the proposed downstream oxygenate provisions discussed in Section VII.F. Consequently, we are proposing a provision in part 1090 that would allow parties downstream of gasoline manufacturing facilities to more easily recertify BOBs for different types and amounts of oxygenates. Specifically, we are proposing a downstream certification mechanism to allow for oxygenate blenders to recertify batches of BOB for different types and amounts of oxygenates as the market demands to make sure that consumers can still have E0, E15, or isobutanol-blended gasoline available as needed. In other words, under part 1090, oxygenate blenders must follow the blending instructions on PTDs by gasoline manufacturers unless they recertify the batch for a different type and/or amount of oxygenate.

We are proposing to require that parties that wish to recertify BOBs must determine the number of sulfur and benzene credits lost by any lack of downstream oxygenate dilution in cases where the party added less oxygenate than was specified by the gasoline manufacturer. For example, if a party takes a premium BOB intended for blending with ethanol at 10 volume percent and wishes to use it as E0 for recreational vehicles, this party would need to make up for the lost dilution of the sulfur and benzene in the national fuel pool. We have included additional compliance calculations that such parties would need to use to determine the number of sulfur and benzene credits needed. In this calculation, we are proposing default assumed values for the amount of sulfur and benzene from the BOB. We are proposing default values of 11 ppm sulfur and 0.68 volume percent benzene. These proposed values are reflective of the national sulfur and benzene average values adjusted for the absence of denatured fuel ethanol added at 10 volume percent ethanol.[87] The goal of these proposed values is to avoid requiring additional sampling and testing from the recertifying party. We believe that due to the small batch volume for recertified product, typically the size of a tanker truck, the amount of credits needed for any given batch of recertified gasoline would be low and small changes from actual benzene and sulfur content would be in the noise of the proposed compliance calculation and washed out in the marketplace. However, we seek comment on whether different default values would be appropriate.

In cases where a party adds the same volume of oxygenate or more, these credit makeup regulations would not apply, as more than enough sulfur and benzene dilution would have occurred. For example, adding 15 volume percent ethanol into a BOB intended for the addition of 10 volume percent ethanol or adding 12 volume percent isobutanol to a batch of BOB intended for the addition of 10 volume percent ethanol. All other applicable requirements under the CAA and parts 79, 80 and 1090 would apply to the recertified fuel. For example, the recertified gasoline would need to meet RVP requirements in the summer, meet per-gallon sulfur requirements, and be substantially similar under CAA section 211(f). Part 80 currently does not allow oxygenate blenders to generate credits in cases where additional oxygenate is added to RBOB or CBOB and part 1090 would not change this. The challenges associated with implementing and enforcing such a credit provision with so many entities on such small volumes has historically created considerable difficulties, and there does not appear to be any compelling reason here to change from the current regulations.

In order to ensure that parties that recertify BOBs downstream adhere to the proposed provisions for downstream oxygenate recertification, we are proposing that these parties would need to register with EPA, transact any needed sulfur and benzene credits, submit annual compliance reports, and keep records documenting the blending activities and reports submitted to EPA. In lieu of requiring the burden of sampling and testing each batch, we are also proposing that these parties simply undergo an annual attest engagement audit and submit an attest report similar to the report required for gasoline manufacturers. The proposed requirements would only apply to parties that incur a deficit by recertifying BOBs with less oxygenate than specified on the PTD. If a party is already registered with EPA and complies with sulfur and benzene averaging requirements, the party would include the total number of credits needed as a result of downstream oxygenate recertification in their annual compliance calculations as a deficit.

During the rule development process, we solicited feedback on whether parties that recertify BOBs downstream should undergo an annual audit to help ensure that the party complied with the proposed requirements correctly. We received feedback from stakeholders stating that while many of the parties that would elect to use this flexibility are already registered with EPA under part 80, these parties often do not have an annual attest engagement as they do not manufacture gasoline. Therefore, these stakeholders argued that having an attest engagement, which costs tens of thousands of dollars per year, for a small volume of fuel (one tanker truck of approximately 8,000 gallons) is unreasonably burdensome and would significantly increase the costs of recertified fuels. We agree with this feedback; however, we believe that parties that recertify a significant amount of gasoline for different types and amounts of oxygenates should undergo an annual audit as these parties could have a greater effect on the larger sulfur and benzene pools. Therefore, we are proposing that parties that recertify less than 200,000 total gallons of gasoline for different types and amounts of oxygenate during a compliance period would be exempt from the annual attest audit and report.[88] We believe this proposed flexibility would allow small blenders to avoid a substantial amount of compliance costs associated with recertification of batches of gasoline for different types and amounts of oxygenates while ensuring integrity in the sulfur and benzene credit markets. We seek comment on whether this allowance is appropriate.

Also, during the rule development process we received feedback asking for alternatives to the proposed downstream oxygenate recertification approach. Stakeholders suggested potentially developing a factor that would go into a gasoline manufacturer's compliance calculations that estimated the nationwide level of oxygenate blended into gasoline. While we believe this measure could effectively capture the amount of oxygenate added downstream, it creates level-playing field concerns by effectively increasing the standard for gasoline manufacturers that certify 100 percent of their batches with oxygenates and decreasing the standards for parties that certify less than 100 percent. Additionally, we believe that setting the factor creates challenges. For example, if we set a level consistent with today's oxygenate blending levels and the market changes the amount of oxygenate added to the fuel pool in the future, we would have to undertake a future rulemaking to accommodate the new amount of oxygenate blended into gasoline. If we put in place an administrative process to adjust the factor on a periodic basis (e.g., annually), we believe it would be challenging to continually monitor and track the appropriate number without imposing significant additional reporting and tracking burdens on the part of industry. Failure to provide a new reporting and tracking mechanism would result in delays in establishing the factor on a periodic basis providing uncertainty for gasoline manufacturers in determining sulfur and benzene average standards. We believe the proposed approach provides the desired marketplace flexibility, puts in place appropriate and manageable measures to ensure environmental performance, and allows for flexibility both now and into the future without the need for additional regulatory action. However, we seek comment on other approaches to allow parties to recertify batches of BOB for different types and amounts of oxygenates downstream.

Finally, during the rule development process, we received feedback asking for an allowance to carry forward a deficit related to downstream oxygenate recertification. Stakeholders suggested that it would take time for the sulfur and benzene credit markets and regulated parties to adjust to this proposed flexibility. They suggested that allowing a limited time deficit carry-forward would allow for this proposed flexibility to be implemented more smoothly. We believe that the amount of credits needed to satisfy deficits incurred related to downstream oxygenate recertification is relatively small and that allowing parties to carry-forward deficits related to this proposed provision would result in some parties failing to satisfy those deficits. Therefore, we are not proposing to allow deficit carry-forwards for deficits created by downstream oxygenate recertification. However, we seek comment on whether providing such a deficit carry-forward is needed to help implement the proposed downstream oxygenate recertification provisions. Comments on this subject should include a reasonable period of time for consideration.

VIII. Registration, Reporting, Product Transfer Document, and Recordkeeping Requirements

A. Overview

We are mostly transferring the existing part 80 registration, reporting, PTD, and recordkeeping provisions that are distributed among various subparts in part 80 to part 1090. We also intend to reconcile, simplify, and logically organize those provisions. The resulting registration, reporting, product transfer document (PTD), and recordkeeping requirements proposed for part 1090 are like those already in place under part 80. Where possible we have sought to reduce the impacts upon regulated parties and reduce the burden associated with maintaining and submitting information. In certain cases, we have proposed regulations to simplify or better align reporting requirements with current industry practice, which is particularly true of the batch reporting requirements described in greater detail below.

Information submitted under part 1090 may be claimed as confidential business information (CBI) by the submitter, including certain information submitted via registration and reporting systems. EPA will protect such information from public release in accordance with the provisions of 40 CFR part 2 and in a manner consistent with EPA rules and guidelines related to CBI. Our public release of EPA enforcement-related determinations and EPA actions, together with basic information regarding the party or parties involved and the parameter(s) or credits affected, does not involve the release of information that is entitled to treatment as CBI. Such information may include the company name and company identification number, the facility name and facility identification number, the total quantity of fuel and parameter, and the time period when the violation occurred. Enforcement-related determinations and actions within the scope of this release of information include notices of violation, administrative complaints, civil complaints, criminal information, and criminal indictments. Although we are not proposing a comprehensive CBI determination at this time, we may undertake that activity in a future rulemaking.

B. Registration

1. Purpose of Registration

Registration is necessary to: (1) Identify which parties engage in regulated activities under our regulations; (2) allow regulated parties access to systems to submit information required under our fuel quality regulations; and (3) provide regulated parties with company and compliance-level identification numbers for producing PTDs and other records. This action would make modest changes to the existing registration system including modernizing certain terminology and making updates that make registration easier to understand and implement.

2. Who Must Register

The proposed registration requirements are designed to update terminology to better reflect current roles and activities in the fuel production and distribution system. We are proposing registration requirements for certain third parties, such as independent auditors. These are explained in greater detail below. The following parties would have to register with EPA prior to engaging in any activity under part 1090:

  • Gasoline manufacturers
  • Diesel fuel and ECA marine manufacturers
  • Oxygenate blenders
  • Oxygenate producers
  • Certified butane blenders
  • Certified pentane producers
  • Certified pentane blenders
  • Transmix processors
  • Certified ethanol denaturant producers
  • Distributors, carriers and resellers who are part of a 500 ppm LM diesel chain and who are part of a compliance plan proposed under 40 CFR 1090.515(c)
  • Independent surveyors
  • Auditors
  • Third parties who require access to EPA's registration and reporting systems, including those who submit reports on behalf of any party regulated under part 1090

Nearly all parties who would be subject to registration under part 1090 are already registered under part 80. We are not requiring parties who are already registered under part 80 to go through the effort to re-register their company or their facilities under part 1090. We are proposing to include specific provisions in part 1090 that would ensure such parties do not need to re-register. For example, although we do not currently register parties under part 80 as “gasoline manufacturers,” parties who are currently registered as “refiners” would be understood to fall under this new term and would not have to re-register. We do not believe that this action will result in a significant number of new registrants, and existing registrants would only need to make the type of routine registration updates they already are required to make (e.g., to add or delete activities they engage in or to change an address).

We are also proposing to remove an existing registration requirement under part 80. Although independent laboratories are required to register under part 80, we are proposing to remove this registration requirement and are not transferring this requirement from part 80 to part 1090. As a result, independent laboratories would no longer be required to register unless they submit information directly on behalf of another party, such as a gasoline manufacturer. In such cases, they would need to update their registration to reflect that they are submitting reports on behalf of a regulated party and would have to associate with the company or companies for which they will submit reports. Association is a step within the existing registration system and is designed to ensure that the company for which the reports are submitted by the “agent” agrees to that arrangement. Association is designed to be a simple step that would still prevent an unauthorized party from submitting reports on another's behalf without their consent or knowledge.[89]

We are also proposing new registration requirements for independent surveyors and independent auditors under part 1090. These parties are not subject to registration requirements under part 80 but either submit survey plans and periodic reports to EPA under various provisions or perform attest engagements for regulated parties under part 80. We thus believe that requiring them to register would allow them to submit reports directly to EPA and thereby further streamline the process of getting the information to EPA.

Independent surveyors perform the compliance surveys and the proposed voluntary sampling oversight program (discussed in more detail in Section X). At present, there is only one known independent surveyor, performing four types of surveys under part 80. As previously noted, independent surveyors already submit survey reports to EPA, in a variety of ways. As discussed in Section VIII.C.8, we are proposing to have them register so that they may submit reports via EPA's reporting systems. Although this would create a small, new class of registrants (currently only one new submitter), we believe the burden of registering is outweighed by the simplicity and reliability of having surveyors utilizing the electronic reporting system to submit their information. This proposed change would allow us to more quickly publicly post in-use survey results.

As also previously noted, independent auditors already perform attest engagements on behalf of parties who are required to demonstrate compliance via reporting. Under part 80, the regulated party (e.g., a gasoline manufacturer) is required to hire an auditor to perform the attest engagement, and the auditor gives the attest engagement to the party who then must submit it to EPA. In order to streamline the reporting process, we are proposing to require auditors to submit the attest engagement directly to EPA in a manner that ensures that the party for whom it was prepared is aware of the submission to EPA. To implement this change, auditors would register and associate with the party to submit reports directly to EPA. Association will ensure that the regulated party knows and agrees that the auditor is submitting their report.

3. What Is Included in Registration

Similar to existing provisions in part 80, registration under part 1090 would entail submitting general information about the company and its compliance-level activities (e.g., facilities), including the address, activities engaged in, name of a responsible corporate officer (RCO), contact information, and location of records. Parties who submit reports to EPA must complete the steps required to set up an account with EPA's Central Data Exchange (CDX) and/or with OTAQ Registration (OTAQReg). Most regulated parties affected by this action have already registered and have already set up the necessary accounts.

4. Deadlines for Registration

We are proposing that registration must occur prior to a party engaging in any activity that requires registration, but we are not specifying a firm deadline for registration as we have in the past. Under part 80, new registrants had to register 60 days prior to engaging in activity. This timeframe remains a useful guideline, however, as we must be allowed an appropriate amount of time to process and activate registration-related requests. We are retaining the requirements from part 80 that updates to existing registration must occur within 30 days of the event requiring the change. We do not expect many new registrants and existing registrants would continue to be registered under part 1090. However, we do anticipate registering up to 100 attest auditors, one surveyor, and 50 third parties. We have docketed a detailed ICR supporting statement that describes the recordkeeping and reporting (including registration) burden in terms of number of parties, hours, and dollars.

Company and compliance-level (e.g., facility) identification numbers already in use will remain valid under part 1090.

5. Proposed Approach to Changes in Ownership

In part 1090 we have sought to address some on-going issues and concerns regarding registration updates. For example, we have received feedback over the years from registrants that changes in ownership should be addressed more clearly in the registration section. Consequently, we are proposing provisions to clarify how a company may initiate a change in ownership for registration purposes. The proposed provisions on updating registrations for ownership change largely codify existing guidance provided to companies under part 80.

Proposed provisions in part 1090 clarify that companies would have to notify EPA of a change in ownership and, in cases requiring registration of a new company, complete registration prior to engaging in any activity requiring registration under part 1090. In the case of a change in ownership requiring an update to an existing registration, the company would need to complete the registration update within 30 days of the change. For any party that is a fuel or fuel additive manufacturer, the new owner would need to be in full compliance with any applicable part 79 registration requirements. Since part 1090 registration is needed in order to report and engage in credit transactions and comply with the fuel quality regulations, parties have great incentive to submit ownership change information to EPA as soon as it is available. We have received feedback from stakeholders who have told us that having a requirement that they submit ownership change information by a specific, advance deadline (e.g., 60 days before the change in ownership occurs) is not workable due to how ownership changes are effectuated in the business world. Although we are not proposing a specific, advance deadline, we note that it typically takes some time for EPA to process a new registration and urge companies to attempt to submit materials as soon as possible and to consider that 60 days prior is a good guideline. Based on our experience with ownership changes under part 80, companies want EPA to activate registration changes for ownership changes in a timely manner to ensure that registrations are up-to-date and that the company can engage in credit generation, trading, and use as soon as practical. Often, these companies request a specific date for the ownership change to be reflected with respect to their registration. Because many ownership changes in the fuel quality programs are quite complicated and involve many facilities, in order for EPA to reasonably act on this type of registration update, we need adequate time to process registration changes.

We believe common ownership changes may include: Companies and/or facilities that are bought in their entirety by another party; companies and/or facilities whose majority owner changes; or a merger resulting in creation of a new company and/or facility. We are not proposing a specific list of documentation that parties may have to submit to support a change in ownership affecting their registration. What documentation, if any, is needed is highly situational. However, we do have experience with typical documentation submitted by parties that may be appropriate, and that may include: sale documentation or contract (portions may be claimed as CBI and redacted); Articles of Incorporation, Certificate of Incorporation, or Corporate Charter issued by a state; and/or other legal documents showing ownership (e.g., deeds). Parties anticipating the need to update registration due to a change in ownership should contact EPA as soon as possible in order to discuss their unique situation.

6. Proposed Approach to Cancellation of Registration

We are proposing provisions regarding voluntary and involuntary cancellation of registration. Similar provisions exist for the RFS program in 40 CFR part 80, subpart M, and we believe they work well for both compliance and compliance assistance purposes; therefore, we are proposing to adopt them for part 1090.

Voluntary cancellation would be initiated by the registered party (e.g., if the party's business changes and it no longer engages in an activity that requires registration).

Involuntary cancellation would be initiated by EPA, typically in cases where the party has failed to submit required reports or attest engagements, or for a prolonged period of inactivity. Specifically, involuntary cancellation may occur where:

  • The party has not accessed its account or engaged in any registration or reporting activity within 24 months.
  • The party has failed to comply with any registration requirements, such as updating needed information.
  • The party has failed to submit any required notification or report within 30 days of the required submission date.
  • The attest engagement has not been received within 30 days of the required submission date.
  • The party fails to pay a penalty or to perform any requirements under the terms of a court order, administrative order, consent decree, or administrative settlement between the party and EPA.
  • The party submits false or incomplete information.
  • The party denies EPA access or prevents EPA from completing authorized activities under sections 114 or 208 of the CAA despite presenting a warrant or court order. This includes a failure to provide reasonable assistance.
  • The party fails to keep or provide the records required by part 1090.
  • The party otherwise circumvents the intent of the CAA or part 1090.

We would provide notification of our intention to cancel the party's registration and the registrant would have an opportunity to address any deficiencies identified in the notice (e.g., to submit required reports) or to explain why no deficiency exists. If we do not receive missing reports within 14 days of notification, then the registration may be canceled without further notice. We believe it is important to have a procedure to keep registrations up-to-date and to ensure that parties perform activities required to maintain active registration.

We are proposing that in instances of willfulness or those in which public health, interest, or safety requires otherwise, EPA may deactivate the registration of the party without any notice to the party. In such cases, we will provide written notification to the RCO identifying the reason(s) EPA deactivated the registration of the party. We expect such situations to be extreme and rare and intend to follow the notice and response provisions described above in nearly all cases.

C. Reporting

1. Purpose of Reporting

We require reports from regulated parties for the following reasons: (1) To monitor compliance with standards necessary to protect human health and the environment; (2) to allow regulated parties to comply with average standards via the use of credits and credit trading systems; (3) to have accurate information to inform EPA decisions; and (4) to promote public transparency. Regulated parties submit various reports to EPA under both parts 79 and 80. Part 1090 updates and, in many cases simplifies, what must already be reported to EPA under part 80. As described further in this section, we are proposing to reduce the number of parameters to be tested and reported and, in some cases, to reduce the required frequency of reporting.

2. Who Must Report

The following parties would have to report under part 1090:

  • Gasoline manufacturers
  • Diesel manufacturers and ECA marine manufacturers
  • Transmix Processors
  • Oxygenate producers
  • Certified butane blenders
  • Certified pentane producers
  • Certified pentane blenders
  • Independent surveyors
  • Auditors

As discussed earlier in this section, certain parties are required to register to receive company and compliance-level identification numbers for use on PTDs and for recordkeeping, although they would not have reporting requirements under part 1090. For example, parties involved in the manufacture and distribution of 500 ppm LM diesel fuel would register and receive company and compliance-level identification numbers to use on PTDs and records but would not submit reports under this part 1090.

3. What Is New With This Proposal

We are proposing to eliminate reporting of the following gasoline parameters that are currently collected under part 80 and no longer necessary under part 1090 to certify batches and demonstrate compliance with the RFG standards (discussed in more detail in Section V.A.2):

  • Aromatics and the associated test method
  • Olefins and the associated test method
  • Methanol and the associated test method
  • MTBE and the associated test method
  • Ethanol and the associated test method
  • ETBE and the associated test method
  • TAME and the associated test method
  • T-Butanol and the associated test method
  • T50 and the associated test method
  • T90 and the associated test method
  • E200 and the associated test method
  • E300 and the associated test method
  • Toxics
  • VOCs
  • Exhaust Toxics Emission
  • Other identifying information (i.e., Batch Grade, lab waiver, Independent lab analysis requirement)

We are proposing to retain only four main parameters for gasoline reporting: Sulfur, benzene, RVP, and oxygenate type/content.[90] We believe the parameters we are proposing to eliminate from reporting, although once useful, are no longer needed in reports, as discussed in Section V.A.2. Removing these parameters would reduce compliance costs related to reporting, sampling, and testing, without sacrificing our goal of protecting human health and the environment. We are also proposing to simplify the annual, batch, and credit transactions reporting, which result in many fewer forms and data elements for respondents.

There are currently numerous reporting forms in use under part 80; we seek to simplify and reduce the number of forms under part 1090. Proposed reporting formats are available in the docket for this action and have also been included in the information collection request (ICR) described in Section XV.C.

4. Proposed Reporting Requirements for Gasoline Manufacturers

As previously discussed, we are transferring the current part 80 requirements for annual, batch, and credit transaction reporting for gasoline manufacturers to part 1090. We are proposing to: (1) Reduce the number of parameters and test methods to be reported under part 1090 as compared to part 80; and (2) simplify the method of reporting. The proposed reporting requirements for these parties includes the following:

  • Annual compliance demonstration for sulfur, to include information about the total volume of gasoline produced or imported, the compliance sulfur value, summary information about sulfur credits owned, generated, retired, etc., and information about credit deficits. This information is like the information already required and submitted under part 80.
  • Annual compliance demonstration for benzene, to include information about the total volume of gasoline produced or imported, the compliance benzene value, summary information benzene credits owned, generated, retired, etc., and information about credit deficits. This information is like the information already required and submitted under part 80.
  • Batch reporting, including information about individual batches of gasoline, to include information about the date of production or import, the volume, the designation of the gasoline or BOB, the tested sulfur and benzene content of the batch, and the tested RVP for summer gasoline or BOB. The proposed regulations address reporting for a variety of gasoline products and reporting scenarios and explains reporting for specific scenarios, such as the reporting for blendstocks added by gasoline manufacturers to PCG by either the compliance by addition or compliance by subtraction method and reporting for blending of certified butane or pentane. We have prepared a technical memorandum and a detailed color-coded batch reporting summary table reflecting the information to be submitted for a variety of products. This information is available in the docket for this action and has been provided as an addendum to the ICR described in Section XV.C.
  • Credit transaction reporting, including information about the generation, purchase, sale, retirement, etc. of sulfur and benzene credits. This information is like the information already required and submitted under part 80.
  • Attest engagements. Under part 1090, there is a change to the method of submission of annual attest engagements. As discussed above, we are proposing to add independent auditors to the list of parties that can submit attest engagements, provided that they first register with EPA and are associated with a company. To ensure the party for whom the attest engagement is prepared is aware, we are proposing that the independent auditor and the company for whom they are preparing the report must associate within the registration system. The existing attest engagement requirements are sprinkled around part 80; this action would condense the existing requirements into a single subpart (subpart R). We are also proposing to align the submission of the attest engagements for the RFS program so that they would be submitted directly by the independent auditor and to include association, as well. We are aware that some regulated parties have expressed concern that they would not know if their attest engagement has been submitted by the auditor and would not be afforded time to review and respond to the auditor's findings. To address this concern, we are requesting comment from regulated parties on what information and required steps are needed prior to submission by the attest auditor. The attest engagement submission would require a description of the findings and the steps the regulated party will take to address remedial actions, but does not necessarily require the remedial action steps to all occur before submission. Attest engagements are discussed in detail in Section XII.B.

5. Proposed Reporting Requirements for Gasoline Manufacturers That Recertify BOB for Different Type(s) and Amount(s) of Oxygenate

In order to implement the proposed optional provisions discussed in Section VII.G with respect to treatment of BOBs, we are proposing reporting requirements for gasoline manufacturers that recertify BOB for different types and amounts of oxygenate. When a person recertifies a BOB with less oxygenate than specified by the fuel manufacturer, they would be required to submit information about recertification activity on a batch level report and include any deficits incurred in their annual sulfur and benzene compliance report.[91] Credit transactions associated with re-certification of the BOB would also be reported. Similar to what is currently allowed under part 80 for certified butane and pentane blending, we are proposing to allow parties that recertify BOBs to include all volumes and deficits in a single reported batch of up to 30 days. This will help minimize the potential reporting burden associated with this requirement.

6. Proposed Reporting for Oxygenate Producers and Importers

We are proposing that oxygenate producers and importers must continue under part 1090 to submit batch reports providing information about the oxygenate they produce or import as already required under part 80. Reporting for oxygenate producers would be on a compliance-level (e.g., facility) basis. The information to be submitted includes information about the oxygenate produced or imported, including the sulfur content of the batch and the test method used. For denatured ethanol, the report would specify whether the denaturant is certified ethanol denaturant or non-certified. The information contained in these reports does not differ from current part 80 reporting requirements, but the proposed regulation is designed to standardize the type and format of the information submitted.

7. Proposed Reporting for Certified Pentane Producers and Importers

We are proposing that certified pentane producers and importers submit batch reports that provide information about the certified pentane produced or imported, including the pentane, sulfur, and benzene content of each batch and the test methods used. The information contained in these reports does not differ from current part 80 reporting requirements, but the proposed regulation is designed to standardize the type and format of the information submitted.

8. Proposed Reporting by Diesel Manufacturers

We are proposing limited batch reporting for manufacturers of diesel fuel. Specifically, we are proposing that manufacturers of diesel fuel (excluding 500 LM from transmix) that test any batch found to exceed the applicable 15 ppm sulfur standard would report information about that batch. Batches that do not exceed the applicable 15 ppm sulfur standard would not be reported to EPA. The specific information proposed to be reported includes the company and facility identifier, the batch identifier, and the tested sulfur content in ppm, and test method used. Since diesel manufacturers are required to test their product for sulfur content and must retain information related to sampling and test results already, we believe the burden of reporting a relatively small number of batches found to exceed the applicable 15 ppm is small. We acknowledge that diesel sulfur batch reporting under 40 CFR part 80, subpart I, generally ended on September 1, 2014; however, the requirement to test and retain records related to sulfur content continues. We are proposing limited batch reporting because we believe it will assist us in our compliance oversight efforts and in ensuring that the human health and environmental benefits of the program are realized.

We also collect some information about diesel sulfur via the annual fuel manufacturer reports, required under part 79. The existing reports are limited in their contemporary value for several reasons. First, they require only information about highway diesel fuel and do not include NRLM diesel fuel. Second, they require information on a manufacturer level, rather than on a facility/refinery level and, therefore, are of limited use for compliance purposes. Third, the high/low/average sulfur values are collected as a volume percentage rather than in ppm, a throwback to the 1970s when diesel sulfur levels were not regulated and sulfur content was much higher. Our purpose in collecting this information at that time was to understand, on a high level, the general characteristics of fuel that may affect human health and the environment and to determine whether future regulation might be needed. The part 79 reports have historically collected the information to the extent known by the manufacturer. Although manufacturers of diesel fuel have been submitting the information, it is submitted in an inconsistent format. For example, we typically receive values expressed in ppm already, as the use of volume percent is no longer the preferred method.

We are proposing to transition diesel sulfur reporting from part 79 and move it entirely into part 1090 reporting forms. This transition includes reporting total volume and max/average sulfur results (using ppm as the unit of measure) by company ID and five-digit reporting ID (i.e., facility ID).

9. Reports by Independent Surveyors

As previously discussed, we are proposing to remove the requirement for registration and submission of reports by independent laboratories and also proposing a requirement for registration and reporting by independent surveyors. The proposed registration requirement for independent surveyors are discussed in greater detail in Section X.A.2.d. For reporting purposes, an independent surveyor must submit plans, notifications, and quarterly survey reports to EPA electronically. The quarterly reports include information about retail outlets visited by the independent surveyor and the characteristics of the fuels samples and tested (e.g., oxygenate type and amount, sulfur content, benzene content, etc.). Independent surveyors would also have an annual reporting requirement that addresses summary statistics and describes compliance rates and non-compliance issues. For the proposed national survey program, this type of information is already collected as part of the part 80 survey programs. Information collected under the proposed national sampling oversight program is like information already collected under the RFG independent laboratory testing program under part 80.

10. Deadlines for Reporting

We are proposing that the annual reports by independent surveyors must be submitted by March 31. We are retaining the existing deadlines for reports under part 80 for reports submitted under part 1090. Specifically:

  • Annual compliance reports for sulfur and benzene would continue to be submitted by March 31 for the preceding compliance period (e.g., reports covering the calendar year 2021 must be submitted to EPA by March 31, 2022).
  • Batch reports would be submitted by March 31 for the preceding compliance period. This was previously the fourth quarter batch reporting due date. We are proposing to reduce the frequency of batch reporting that currently applies under part 80, going from quarterly to annually.
  • Attest engagements would continue to be submitted by the independent auditor by June 1 for the preceding compliance period.
  • Reports by independent surveyors would continue to be submitted quarterly on June 1 (covering January 1-March 31), September 1 (covering April 1-June 30), December 1 (covering July 1-September 30), and March 31 (covering October 1-December 31). Annual reports by independent surveyors must be submitted by March 31.

11. Proposed Reporting Forms

Proposed reporting formats are discussed in more detail in the technical memorandum covering batch reporting, available in the docket for this action, and in the ICR. The ICR includes actual proposed reporting instructions. Interested parties are urged to review these materials and provide feedback.

The information collected in the proposed reports should be familiar to existing registered and reporting parties. We have designed part 1090 and the proposed reports to address areas where reporting requirements were previously unclear or cumbersome and to reduce the existing reporting burden.

D. Product Transfer Documents (PTDs)

The general purpose and requirements for PTDs do not differ from the existing requirements in part 80. PTDs are documents generated in the normal course of business that provided a clear description of the product being transferred. Under part 1090, PTDs would still be required each time a person transfers title or custody to a product regulated under part 1090. The typical format of PTDs is not changed by this action—basic information including identification of the transferor/transferee, location of the transfer, volume and type of product, etc. remain familiar. As with existing part 80, commonly understood codes may be used by “upstream parties” and where a transfer is made to those other than truck carriers, retailers, or wholesale purchaser-consumers (WPCs). Transfers to truck carriers, retailers, or WPCs would require the specified, printed statement and product information rather than a code. As with existing part 80, PTDs would have to be kept by each transferor and transferee.

Part 1090 mostly consolidates the various PTD language requirements throughout part 80 into a single, consistent section to help bring uniformity to the PTD language across fuels, fuel additives, and regulated parties. This action would remove PTD language that is no longer needed and provide standard, updated language to address a variety of common products and situations. We are, however, proposing some minor modifications from the existing part 80 requirements.

We are proposing language to identify fuel covered by all known, specific exemptions (e.g., R&D exemption, racing fuel exemption, etc.) in a more consistent manner. Part 80 only requires that exempt fuels be identified on PTDs as exempt and is inconsistent with its language requirements across the various part 80 fuel quality programs. We intend to make our PTD requirements more consistent so we are proposing a more prescriptive format for exempt fuels.

Under some programs in part 80, we have allowed parties to petition for alternative PTD language for some PTD requirements, but not for other PTD requirements. During the rule development process, several stakeholders highlighted that instances exist where our PTD requirements may conflict with other federal, state, or local PTD or identification requirements. In such cases, fuels, fuel additives, or regulated blendstocks could be identified with contradictory language that makes it difficult for parties in the fuel distribution system to comply with all applicable federal, state, and local requirements. To address these potential issues, we are also proposing to allow parties to seek approval for alternative PTD language for all proposed PTD language requirements. Based on experience implementing part 80, we do not anticipate that many parties will request alternative PTD language.

E. Recordkeeping

We are maintaining the record retention requirements in part 80. All parties that keep records under part 80 would continue to keep the same or similar records under part 1090. Records that must be maintained are those already familiar to regulated parties, including: Information that supports the registration and reports submitted to EPA, information related to waivers (such as R&D programs), copies of PTDs, sampling and test results and related laboratory documents, information about credit transactions for sulfur and benzene, and information related to compliance calculations. We anticipate that the number of records retained will decrease under part 1090, in large part because the number of sampled, tested, and reported parameters for gasoline and certain regulated blendstocks would decrease.

F. Rounding

The standards and compliance requirements under part 1090 require extensive use of numbers to quantify fuel parameters and fuel volumes, along with numerous occasions to calculate new quantities to properly document compliance. A rigorous compliance demonstration depends on properly managing precision and significant figures in recorded values and calculations. Part 80 addresses rounding and precision by simply instructing regulated parties to round test results to the nearest unit of significant digits specified in the applicable fuel standard as described in ASTM E29. We are proposing a much broader and consistent approach in part 1090. We codified a standard approach to rounding in 40 CFR 1065.20 that is consistent with ASTM E29. We are proposing to apply this rounding protocol to all recorded values under part 1090.

The action includes additional specifications for calculating and recording numerical values. First, we are proposing to specify that rounding intermediate values in a calculation is not appropriate. This principle is intended to preserve the accuracy and precision until the calculations reach a final result, at which point the final result can be rounded to the appropriate number of decimal places or significant figures. We recognize that intermediate values must sometimes be transcribed (such as from an analyzer to a spreadsheet), which cannot be done with infinite precision. We are therefore proposing that intermediate values should be recorded and used with full precision, except that rounding is permissible if the value retains at least six significant digits. This is not a proposal to require six significant digits for all recorded values. Rather, if an intermediate quantity with more than six significant digits needs to be transcribed, parties may use the specified rounding protocol to eliminate the additional digits. Also note that we generally allow for using measurement devices that incorporate proper internal rounding protocols to report test results.

Second, multiplying a value by a percentage must keep the precision of the original value. This is equivalent to considering the specified percentage to be infinitely precise. For example, calculating 1 percent or 1.0 percent of 1,234 would result in a value of 12.34. This is relevant for calculating an averaging standard for benzene. Fuel volume is multiplied by exactly 0.62 percent, rather than using a value of 0.624 (which rounds down to 0.62) before multiplying by fuel volume.

G. Certification and Designation of Batches

The certification and designation of batches of fuels, fuel additives, and regulated blendstocks are crucial elements to ensuring that fuels, fuel additives, and regulated blendstocks meet our fuel quality standards and aid in the distribution of such products. Certification is the process where a manufacturer or producer demonstrates that their product meets EPA's standards. Designation is the identification of a batch (typically on PTDs) as meeting specific requirements for a category of fuel (e.g., summer RFG), fuel additive (e.g., diesel fuel additives), or regulated blendstocks (e.g., certified butane or certified pentane). Parties throughout the fuel distribution system rely on designations to appropriately transport, store, dispense, and sell fuels. Part 80 generally has provisions for certification and designation of products separately for each program. Part 1090 consolidates these various certification and designation procedures into a single set of provisions.

Regarding certification, most of the certification procedures for fuels, fuel additives, and regulated blendstocks for part 80 are outlined in guidance. We are proposing in part 1090 to incorporate such guidance into the regulations and establishes a clear process to certify batches. The proposed regulations include the following four steps:

  • Registration prior to the production of fuel, fuel additive, or regulated blendstock (if required).
  • Sampling and testing the fuel, fuel additive, or regulated blendstock to demonstrate that the product meets applicable quality standards.
  • Assignment of a batch identification number (if required).
  • Designation of the batch as appropriate.

We believe these four steps are consistent with how parties currently certify products under part 80. These requirements satisfy CAA section 211(k)(4) describing certification procedures for RFG.

Regarding designation, for gasoline and gasoline-related additives and regulated blendstocks, we are proposing to substantially modify the designation requirements for these products. Most of these proposed changes reflect the removal of the Complex Model for use in the certification of batches of RFG and the harmonization of the RFG and CG programs. Many of the prior designations to segregate RFG and CG are no longer necessary, so we are proposing to remove those designations. Additionally, we are proposing more flexible redesignation provisions for distributors of gasoline. These proposed provisions largely reflect the proposed streamlining of the RFG program and the more fungible nature that would result.

Distributors of gasoline would be allowed to redesignate winter RFG/RBOB to winter CG/CBOB (and vice versa) and summer gasoline from a more stringent RVP standard to a less stringent RVP standard without recertification (e.g., from summer RFG meeting the 7.4 psi RVP standard to 9.0 psi RVP summer CG). Any person that mixes summer gasoline with summer or winter gasoline that has a different RVP designation must either designate the resulting mixture as meeting the least stringent RVP designation of any batch in the blend or determine the RVP of the mixture and designate the new batch accurately to reflect the RVP of the gasoline as described under this section. When transitioning from winter to summer gasoline, parties are not required to test the RVP but must exercise good engineering judgement to assure that the gasoline meets the applicable RVP standard.

We are also making it clear that parties can redesignate California gasoline that meets CARB standards without recertification, as explained in more detail in Section VI.A. We believe these flexibilities will help maximize the fungibility of gasoline.

For diesel fuel, diesel additives, and diesel regulated blendstocks, we are largely proposing to maintain the part 80 designation requirements. We are, however, proposing two notable changes. First, we are proposing a more flexible designation scheme for distillate fuels certified to meet ULSD standards. The intent of the proposed regulations is to ensure that fuels that meet the ULSD standards could be designated as necessary to be used as home heating oil, motor vehicle, nonroad, locomotive, or marine diesel fuel (defined as MVNLRM diesel fuel in part 80), or IMO marine fuel. This change would allow parties to make sure that fuels are designated appropriately throughout the distribution system.[92] Second, similarly to gasoline, we are proposing to allow parties to redesignate California diesel fuel that meets the ULSD standards without recertification. We believe the proposed designation changes for diesel fuel would help maximize the fungibility of distillate fuels that meet the ULSD standards.

We seek comment on the proposed certification and designation provisions.

IX. Sampling, Testing, and Retention Requirements

Our fuel quality programs consists of performance standards and compliance provisions that require measurement of various fuel parameters. These measurements in turn rely on specified procedures contained in part 80. We are transferring these same test procedures from part 80 into part 1090. We are also reorganizing the testing provisions in part 1090 and proposing several clarifications to reflect current best practices. We are further consolidating test procedures for gasoline and diesel fuel in some cases. This section highlights the proposed changes relative to what currently applies under part 80.[93]

A. Overview and Scope of Testing

Part 80 requires gasoline manufacturers to measure 11 complex model parameters. This action would significantly reduce the number of parameters that gasoline manufacturers must measure for determining compliance with the fuel standards. Part 1090 would require fuel manufacturers to measure the sulfur and benzene content of every batch of gasoline and to measure the RVP of every batch of summer gasoline. Fuel manufacturers will also be required to sample and test for oxygenates in specific situations when EPA believes it could be difficult for the fuel manufacturer to assure compliance with oxygenate standards without sampling and testing the gasoline. For gasoline produced at a blending manufacturing facility or a transmix processing facility, we are retaining the part 80 requirement to test gasoline for distillation parameters. The distillation testing provides a distillation curve that shows how much of the gasoline has flashed off as the temperature of the sample is increased. This curve can provide some confirmation that the blended product has a distillation profile that is generally consistent with gasoline meeting the substantially similar requirements of the CAA. The results of the distillation testing would not be required to be reported, but instead would be retained at the facility to provide additional data that can be reviewed in the event of complaints about potential compliance or performance issues. We understand that distillation parameters are effectively a condition of merchantability of gasoline in the U.S., so such testing is already being performed by fuel manufacturers.

Part 80 requires RFG refiners to obtain test results for all parameters required to determine compliance. Part 80 also requires CG refiners to measure sulfur content in gasoline and diesel fuel prior to introduction into commerce. Requiring measurement before shipping from the refinery provides assurance of compliance prior to the fuel being mixed and commingled in the fungible distribution system and potentially even consumed. Unlike many regulatory situations where it is possible to go back after the fact and correct the noncompliance, this is difficult if not impossible in most situations for fuel once it has left the fuel manufacturing facility. Consistent with part 80, we are proposing to require all gasoline manufacturers to obtain test results for sulfur and RVP (during the summer months) before shipping gasoline from the fuel manufacturing facility. Part 80 requires RFG refiners to obtain test results for benzene before shipping gasoline, but does not require CG refiners to obtain these results before shipping from the refinery. We are not proposing to require gasoline manufacturers to test for benzene before shipping gasoline from the fuel manufacturing facility, but we are seeking comment on whether this would be appropriate. Some fuel manufacturers have suggested that being able to test after shipping product from the fuel manufacturing facility would make the testing substantially less burdensome. Taking time to perform testing and verify results can cause delays in managing the flow of producing and shipping product. We are not revising fuel requirements that impose the obligation to test fuels before shipping from the fuel manufacturing facility. With the simplified test requirements of the streamlined program, we believe there is no justification to avoid the compliance-assurance advantage of individual batch measurements whenever that is possible. However, we seek comment on this and what provisions could be put in place in its absence to provide assurance that the fuel met the standards in the absence of testing. For example, we could require fuel manufacturers to keep records documenting their engineering assessment that supports a conclusion that the fuel meets applicable standards despite the absence of test results. Such an assessment would need to account for varying refinery processes, maintenance or other system changes, personnel changes, source and quality of any blending components, and any other relevant variables.

We are maintaining exceptions to testing under current waivers that do not require measurement of fuel properties prior to shipment. Currently 40 CFR 80.65, 80.581, and 80.1630 describe separate programs for in-line blending configurations to qualify for a waiver from the test-before-ship requirements as part of an approved process with annual quality audits. We are transferring these existing provisions that allow for the in-line blending waiver only for shipment configurations because they do not allow for conventional batch testing. For example, sending finished fuel directly into a pipeline or a marine vessel generally does not allow for conventional batch measurement, so we expect refiners to continue to rely on the in-line blending waiver for these shipping arrangements. Refiners are similarly prevented from timely batch measurements if they create fuel batches that are greater than they can contain in a single storage tank. We are therefore transferring these existing part 80 waiver provisions for in-line blending also to operations that involve these over-sized batches to part 1090. The transferred provisions, when effective, would mean that the restricted application of the in-line blending waiver does not prevent refiners from using automated in-line sampling procedures as described in ASTM D4177 for measuring fuel parameters for a given batch.

B. Handling and Testing Samples

1. Collecting and Preparing Samples for Testing

Accurate test results are dependent on the sample being representative of the fuel batch. We are transferring the sampling procedures and demonstrating homogeneity of fuel samples that are currently specified in 40 CFR 80.8. This provision generally specifies procedures for manual sampling as described in ASTM D4057 or automated in-line sampling as described in ASTM D4177. The additional procedures for sampling related to gasoline RVP as described in ASTM D5842 are also being transferred to part 1090.

Some of the current regulations in part 80 related to sample collection, however, do not adequately address sampling procedures because they do not provide the necessary specifications for testing. We have addressed some of those omissions through guidance documents published over the years.[94] We are also proposing to add numerous minor clarifications and adjustments to the regulatory text to reflect current best sampling practices.

2. Sample Preparation for BOB Testing

Section VII describes the proposed new approach for oxygenate accounting for gasoline that would allow parties that either produce or import BOB and instruct downstream blenders to add oxygenates to meet sampling requirements by blending oxygenates into a BOB sample to represent the final blended fuel—a “hand blend.” [95] This would involve preparing each fuel sample by adding oxygenates to the BOB sample in a way that corresponds to instructions to downstream blenders for the sampled batch of fuel.

Preparing the hand blend sample involves decisions about which samples to use for blending. For example, three tested BOB samples may be available to prepare the hand blend. Also, a single hand blend might represent different types and amounts of oxygenate, as reflected in the blending instructions for downstream parties. We are proposing to address these examples of discretion in the specified procedures by requiring that the hand blend represent a worst-case test condition. In the case of sulfur measurements from multiple samples to represent a batch of BOB, this requires further testing with the sample that has the highest sulfur measurement.

Winter gasoline would need to be blended with the lowest specified percentage of any oxygenate type given in the instructions for downstream blending. For example, if blending instructions specify an 8 percent isobutanol blend in addition to E10 and E15, the hand blend would need to be an 8 percent isobutanol blend. This reflects the fact that dilution is the primary effect of blending on fuel parameters other than RVP. A different approach is necessary to properly select the type and amount of oxygenate for hand blending in summer gasoline. Under this proposal, summer gasoline would need to be blended with the lowest specified percentage of ethanol given in the instructions for downstream blending (i.e., blend for E10 if the instructions identify E10 and E15 for downstream blending, even if the blending instructions include an option to blend with a lower percentage of a different oxygenate).

3. Sample Retention

Part 80 currently describes sample-retention requirements in multiple provisions. Stakeholders have pointed out that there is ambiguity about whether the regulation requires sample retention for 30 or 90 days. We are proposing to require all fuel manufacturers to keep fuel samples used to demonstrate compliance with all applicable standards for 30 days, except for blending manufacturers.

A longer retention time applies for blending manufacturers since these manufacturers typically have less control over the quality of the blendstocks they use to produce gasoline, which can cause decreased fuel quality without robust controls. Crude refineries typically distribute fuels through a distribution network with multiple levels of control to ensure fuel quality (e.g., through pipelines that have strict product specifications prior to injection) while blending manufacturers can make fuels on a more ad hoc basis (e.g., in a tanker truck). We therefore believe it is appropriate to require a longer retention period to help trace potential issues with fuel quality. We are proposing a minimum retention period of 120 days for fuel samples that blending manufacturers use for testing to demonstrate compliance with gasoline or diesel fuel standards.

For testing BOB and hand blended samples of oxygenated gasoline as described in Section IX.C, the sample-retention requirements apply for both the BOB sample and the hand-blended sample used to demonstrate compliance. Gasoline manufacturers producing BOB have expressed a concern that space limitations would make it difficult to store both the BOB sample and the hand-blended sample used to demonstrate compliance. We are therefore proposing that gasoline manufacturers do not need to keep each hand-blended sample; they would instead need to keep a DFE sample to allow them to create new hand-blended samples corresponding to each BOB sample. With this approach, a single DFE sample might be available for blending with multiple BOB samples.

C. Measurement Procedures

Demonstrating compliance with fuel quality standards requires a wide range of measurement procedures. Our fuel quality regulations rely heavily on standardized test methods published by voluntary consensus standards bodies such as ASTM International. As described below, the proposed regulations in part 1090 reference certain measurement procedures, in most cases with provisions allowing for using alternative procedures, including updated versions of referenced procedures in some instances.

1. Procedures for Gasoline Surveys

Testing for gasoline surveys is intended to provide a consistent indication of in-use fuel parameters over time. Testing will generally be performed by a selected set of test labs to represent the range of fuels in distribution over time.

We are proposing to require that survey measurements rely on the referee procedures identified under PBMS, where applicable. The following procedures apply for additional parameters:

  • ASTM D5769 for aromatic content
  • ASTM D6550 for olefin content
  • ASTM D86 for T50 and T90 distillation points

We request comment on the specified procedures for measuring the various fuel parameters for surveys.

2. Procedures To Determine Cetane Index for Diesel Fuel

Part 80 and the Clean Air Act establishes a cetane index standard at or above 40 for diesel fuel used with motor vehicles and nonroad equipment. (See 40 CFR 80.520(a)(2)). Part 80 also references ASTM D976 as the procedure for determining cetane index in diesel fuel. During the development of this action, industry stakeholders advocated for ASTM D4737 as a more robust method that relies on additional fuel parameters for calculating cetane index. In response to stakeholder request, we are proposing that either of the referenced ASTM procedures are acceptable for determining cetane index.

Both of the referenced ASTM procedures are valid for the full range of distillate fuels qualifying as diesel fuel. However, these procedures rely on fuel characteristics for distillate fuel and they are therefore not appropriate for biodiesel. The chemical make-up of pure biodiesel causes it to inherently have higher cetane values and no aromatic content. With no suitable measurement procedure for cetane index in biodiesel, and no concern that biodiesel will fail to meet the cetane index standard or have greater than 35 percent aromatics, we are proposing to exempt biodiesel from testing to verify compliance with the cetane index or aromatic content requirement for diesel fuel.

Additionally, EPA is aware of industry efforts aimed at developing new test methods for determining cetane index and similar parameters related to cetane number. We request comment on incorporating new measurement procedures into part 1090 as an alternative means of demonstrating compliance with the cetane index standard. In particular, we request comment on quantitative correlations between the new procedures with the existing procedures used to determine cetane index. Where appropriate, these comments should address whether such quantitative correlations depend on fuel formulations of properties that may be more or less prevalent than in the past.

3. Performance-Based Measurement System

EPA adopted the Performance-Based Measurement System (PBMS) that establishes objective criteria for qualifying laboratories and measurement procedures (see §§ 80.46 and 80.47). Our fuel quality regulations specify referee test methods for several fuel parameters and define precision and accuracy criteria so laboratories can demonstrate that they qualify their equipment for using the referee procedure, or for using alternative procedures. Precision and accuracy criteria apply for initial qualification, and for ongoing quality checks.

Part 80 includes a specified date for laboratories to omit initial qualification testing if they have been using the specified referee procedure for a given parameter. We are proposing to broaden this approach in part 1090 by allowing laboratories to omit initial qualification testing if they are using the specified referee test procedure. This approach treats all laboratories the same. Since the ongoing quality checks apply for laboratories using these procedures, the laboratories will still be demonstrating that they are properly performing these measurement procedures.

a. Scope

We have received questions on the applicability of PBMS requirements beyond the predominant scenario of testing fuel at a refinery. The PBMS provisions for measuring specified fuel parameters apply to all parties and at all points in the fuel distribution system. PBMS provisions also apply for batch testing for compliance, and for quality audits such as what is required for in-line blending waivers, for test waivers for truck and rail imports, and for blending certified butane and pentane into PCG. Any other approach would be inconsistent with PBMS and would create an unlevel playing field for different market participants.

b. Referee Procedures

We are transferring the same referee procedures for part 1090 that currently apply under part 80, subject to the following proposed exceptions and clarifications.

First, we are proposing to change the designated referee procedure for measuring benzene in gasoline from ASTM D3606 to ASTM D5769. We believe ASTM D5769 is as a superior procedure because measurements involve little or no interference from ethanol blended into gasoline. In contrast, ASTM D3606 has interference effects from ethanol that require careful work to adjust for that interference. Since ASTM D3606 is the referee procedure for measuring benzene in gasoline under part 80, we are proposing to waive requirements to initially qualify testing with ASTM D3606 as an alternative procedure. We believe the ongoing PBMS quality demonstrations are sufficient to demonstrate proper precision and accuracy using ASTM D3606.

Second, we are proposing to remove measurement of aromatic content in diesel fuel from the PBMS protocol. We are not proposing to require aromatic testing for every batch of diesel fuel. As a result, we believe the PBMS protocols for referee procedures, qualifying alternative procedures, and ongoing quality testing are no longer appropriate. We are instead proposing to simply specify that ASTM D1319 and ASTM D5186 are acceptable procedures for measuring aromatic content in diesel fuel and allowing for alternative procedures that correlate with either of these specified procedures.

Part 80 specifies ASTM D6667 as the referee procedure for measuring sulfur in butane. We are proposing to specify the same referee procedure (and precision and accuracy criteria) for measuring sulfur in pentane.

We have also received questions on the applicability of PBMS to oxygenates used in gasoline. We have always intended for the PBMS requirements to apply for testing oxygenates in the same way that test requirements apply for testing gasoline. Accordingly, we are clarifying in part 1090 that oxygenates, including denatured fuel ethanol, are subject to PBMS requirements for all testing under part 1090 in the same way that these requirements apply for testing gasoline. This includes the protocol for qualifying alternative test procedures and the requirements for ongoing quality testing.

c. Updated Versions of Referenced Procedures

Part 80 currently references specific published versions of the various test procedures for measuring fuel parameters. These specific references do not automatically change with periodic updates to those procedures from the publishing organization, which makes it difficult for us to keep the regulations current as the industry continues to improve measurement procedures. To maintain the integrity of the PBMS protocol while allowing for the regulations to remain current with evolving industry practices, we are proposing that laboratories may use updated versions of referee procedures or qualified alternative procedures without our prior approval, as long as the updated version has published repeatability and/or reproducibility that is the same as or better than the version referenced in part 1090.

A similar approach applies for using an updated method of a referee procedure to qualify alternative procedures. Laboratories wanting to do this must first get our approval. We would expect to approve such requests based on a demonstration that the repeatability and reproducibility are the same as or better than the referenced procedure, but we are proposing to establish EPA's approval role to the extent the updated version of the referee procedure is used to qualify new alternative procedures. This interaction will also help us identify instances where we should consider updating the regulation to rely on the latest available procedures.

d. Criteria and Methods for Qualifying Procedures

The precision and accuracy criteria from part 80 are migrating to part 1090 with two exceptions. First, we are proposing to specify precision and accuracy criteria based on the most recently published repeatability values from ASTM D2622 for measuring sulfur in 500 ppm LM diesel fuel and ECA marine fuel. Second, we are proposing to specify precision and accuracy criteria for gasoline benzene based on the most recently published reproducibility values from ASTM D5769 instead of ASTM D3606. The published reproducibility for ASTM D5769 is slightly higher than for ASTM D3606, which means that it allows for a slightly more accommodating approach for qualifying alternative procedures.

We are proposing to transfer part 80 requirements for calculating precision and accuracy criteria for diesel sulfur based on calculated values for sulfur concentrations at fixed values to represent compliance at the standard. This would allow for a fixed criterion for testing all fuel samples. Selecting a test fuel with very low sulfur would not be meaningful, since it is not reasonable to compare such small quantities of measured sulfur to precision and accuracy criteria that are keyed to the standard. As a result, we are simply transferring the same specified minimum sulfur values for measuring sulfur in all the different types of diesel fuel. This becomes problematic for measuring sulfur in neat biodiesel, since it has inherently low sulfur concentrations. We would expect testing to qualify methods or to perform ongoing quality checks with neat biodiesel to include doping the fuel with enough diesel fuel to meet the minimum sulfur specification.

We are proposing to specify that precision and accuracy criteria for all fuel parameters other than sulfur are to be determined based on the actual value of the tested fuel. For example, for precision testing to qualify an alternative method, this would be based on an average value from the 20 tests (or more) used to evaluate precision.

We are also proposing that the between-methods-repeatability, Rxy, for qualifying alternative procedures for method-defined parameters using non-VCSB methods must be at or below 75 percent of the reproducibility of the designated referee procedure. This is an increase from the 70 percent value specified in 40 CFR 80.47. The increase in the specified value for the Rxy criterion is based on the observation that it may be mathematically impossible to achieve a 30 percent improvement over the repeatability of the designated referee procedure. We are not aware of anyone seeking to use a non-VCSB method for fuel-defined procedures, but we want to continue to allow this to be a viable option. We request comment on the appropriateness of the proposed value of 75 percent for the Rxy criterion.

e. Ongoing Testing for Statistical Quality Control

We are further transferring the statistical quality control procedures established under 40 CFR 80.47 to part 1090. However, by rewriting these procedures in their own section, the proposed provisions may clarify some points that were previously subject to differing interpretations. We request comment on the proposed rewrite of the statistical quality control procedures.

X. Proposed Third-Party Survey Provisions

Third-party verification plays an important role in overseeing compliance with our fuel quality programs under the existing part 80. One key element to our existing third-party oversight regime are in-use retail level surveys. An advantage of retail survey programs is that they target fuel quality at the point the fuel is dispensed from a retail outlet. Under part 80, we have four in-use survey programs that primarily focus on RFG and RFG areas, ethanol content, E15 labeling, and ULSD sulfur levels, which are tracked nationally. For the most part, however, we have little or no other retail level information under part 80 for CG, which constitutes about 70 percent of the national gasoline fuel pool. We are proposing a national survey program in part 1090 that would consolidate the four programs into a single national survey in-use retail program, thereby reducing costs, while at the same time expanding the benefits of the survey program nationwide. When finalized, the part 1090 survey would build upon the existing in-use survey provisions, leveraging independent third-parties to a greater extent to ensure that compliant fuels are used in vehicles and engines in exchange for allowing fuel manufacturers greater flexibility to account for oxygenates added downstream in their annual compliance demonstrations,[96] and reducing the number of fuel parameters that fuel manufacturers need to be test and report.

Part 1090 includes two survey programs: a national survey program of retail outlets that offer gasoline and diesel to ensure that in-use standards are met, and a voluntary national sampling and testing oversight program that is intended to help ensure that gasoline manufacturers collect samples for testing in a consistent manner for purposes of compliance with applicable standards and thus, maintain the integrity of our fuel quality program. This section discusses both proposed programs in detail.

A. National Survey Program

As previously explained, we are proposing provisions for a nationwide survey of in-use gasoline and diesel fuel that is intended to ensure that gasoline and diesel fuel meet our applicable fuel quality standards when dispensed into gasoline- and diesel-fueled engines. We have used survey programs to great effect under the existing part 80 regulations. Table X.A-1 outlines the four survey programs currently in part 80 and describes the geographic scope, parties that participate in the survey program, and the estimated sample size.

1. Background

We have historically used survey programs to provide flexibilities in fuel quality programs that we administer, which allows regulated parties to more efficiently meet our fuel quality standards. For example, we provided RFG refiners with the option of complying with RFG requirements on an average basis by demonstrating that RFG meets the applicable in-use oxygen content and NOX, toxics, and summertime VOC performance at retail stations. By being able to rely on an in-use survey at the retail level to verify overall compliance, the regulations thus allow RFG refiners considerable flexibility in their day-to-day operations to produce fuel at the lowest cost. The norm for over 20 years has thus been that RFG refiners and importers produce a sub-octane, oxygenate-free RBOB that is distributed throughout the distribution system to which ethanol is added at downstream terminals. The retail survey then allows for verification that the RFG standards are met in-use. Since most RFG areas are supplied by multiple refiners, we allowed RFG refiners and importers to consolidate resources to establish a survey to demonstrate that RFG standards were met for RFG areas on average.

Additionally, in order to discourage misfueling of vehicles and engines, we have historically imposed pump labeling requirements at the retail level. In order to provide oversight of the thousands of retail stations, we also currently have provisions for a retail outlet survey to ensure that fuel dispensers are labeled appropriately (e.g., E15 programs). A statistically representative sample of retail outlet fuel dispensers gathered through a survey helps inform responsible parties and EPA whether labeling requirements are being met without having to impose direct costs on the retail outlet to demonstrate compliance.

The focus of much of our current compliance oversight has been on parties that manufacture fuels at crude refineries with provisions that then attempt to ensure that the fuel quality as measured at the crude refinery is maintained all the way to retail. What happens at the crude refinery has historically been and continues to be the greatest factor as to whether a fuel is ultimately compliant. However, as the transportation fuel market has continued to evolve and parties at all locations downstream of refineries (e.g., pipeline, terminal, retail) are now increasingly engaged in the process of producing the finished fuel (i.e., adding ethanol or gasoline blendstocks into PCG, or adding biodiesel into diesel fuel), it has likewise become more important to not only receive information from the manufacturers of gasoline and diesel fuel at the start of the process, but also from the end of the process—at retail level—to ensure fuel quality standards are met. In the past this was mostly necessary just for RFG to ensure that the oxygenate was in fact added to the refinery-certified RBOB downstream and the RFG standards were met. However, now that essentially all gasoline has ethanol added downstream to a refinery-produced and/or certified CBOB and many downstream parties are taking actions that can impact fuel quality, all in-use gasoline could benefit from a retail survey. Without it we would not propose the changes discussed in Section VII.F to allow refiners and importers to account for the downstream addition of ethanol in their compliance calculations. Consequently, we are proposing to extend the retail survey that has been applicable for over 20 years in RFG areas nationwide to all gasoline. The proposed national in-use gasoline survey would provide EPA with the data necessary to ensure that in-use gasoline is in fact blended with ethanol as claimed by the gasoline manufacturer, meets our gasoline standards, and continues to meet RFG and anti-dumping statutory requirements. An in-use survey would also enable EPA to provide compliance flexibility to CG refiners and importers similar to RFG refiners and importers.

There are no associated overall increased costs or compliance burden for the proposed expansion of the scope of the survey to all CG. As discussed in Section V.A.2.c, we are proposing a substantial reduction in sampling and testing requirements on gasoline refiners and importers at the refinery/import facility by removing the requirement for the certification of gasoline using the Complex Model. In its place, we are proposing requirements for refiners and importers to test for just sulfur, benzene, RVP in the summer, and oxygenates.

2. Proposed National Survey Program

a. Consolidation and Scope

We are proposing to consolidate the existing four in-use survey programs outlined in Table X.A-1 into a single national survey program. We believe the expanded scope of gasoline samples tested nationwide would help us ensure fuel quality oversight and compliance with our applicable fuel quality standards. This would also allow for providing compliance flexibility for CG refiners and importers to account for oxygenate (as discussed in Section VII.F). As previously explained, the ULSD and E15 survey programs are national surveys of retail stations but only test for sulfur in diesel fuel and ethanol content and RVP in the summer. On the other hand, the RFG survey and RFG ethanol survey are limited to RFG areas but test for the full suite of Complex Model fuel parameters. We believe there is technical support for allowing a survey program to collect a sample that satisfies multiple survey requirements (i.e., as long as retail stations are identified using sound selection procedures, there is no reason an independent surveyor could not obtain both a gasoline and a diesel fuel sample to satisfy all applicable survey program requirements).

The main benefit to stakeholders of consolidation of the current four survey programs into a single program is a substantial reduction in sample size. Currently, the four survey programs require industry participants to contract for over 18,000 fuel samples collected nationwide (see Table X.A-1 above). As further discussed in Section X.A.2.c, we are proposing that the required sample size of our fuels survey programs could be reduced to less than 7,000 retail outlets sampled through consolidation. Since the largest expense in retail surveying is the costs to collect and ship a sample from a retail station, reducing the sample size from more than 18,000 to less than 7,000 would substantially decrease the costs of the program.

The main benefit to EPA is the expanded scope of testing for regulated fuel parameters to all fuel nationwide. Under the existing program, the RFG survey programs test approximately 30 percent of the national gasoline pool for the entire set of Complex Model fuel parameters, while in the nationwide E15 survey, only ethanol content year-round and RVP for E15 samples in the summer are tested.

In addition to consolidating the four survey programs into a single, nationwide program, we are proposing that all gasoline samples would be tested for sulfur, benzene, RVP (in the summer), and oxygenates. A statistically determined subset of the national gasoline sample would be tested for the rest of the Complex Model fuel parameters to allow us to verify that gasoline continues to meet CAA section 211(k) requirements. The survey would continue to ensure E15 pump labeling compliance at retail stations. For diesel, the survey would still test diesel samples for sulfur. We seek comment on the proposed consolidation of the four part 80 survey programs and the proposed expanded scope of the national survey program.

b. Survey Participation

We are not proposing any revisions to the existing survey for fuel and fuel additive manufacturers that make E15 or ethanol for use in making E15, which is the only one of the current surveys that is mandatory. Other gasoline manufacturers would need to participate in the national survey program if they wanted to account for oxygenate added downstream. Under part 80, the RFG regulations impose a similar survey requirement on RFG refiners and importers that account for oxygenate in compliance calculations (see 40 CFR 80.69) and since we are proposing to allow this flexibility for manufacturers of CG, we are proposing to impose a similar survey requirement. We believe that monitoring in-use sulfur, benzene, and oxygenate content is necessary to allow this flexibility for all gasoline manufacturers because without in-use verification from a national survey, there would be no oversight on whether gasoline manufacturers claimed credit for oxygenate that was ultimately not blended.

Under part 1090, parties that participate in the survey would have an affirmative defense for downstream violations of our applicable fuel quality standards. Under part 80, we have provided an affirmative defense for upstream parties that participate in survey programs to ensure downstream compliance for the ULSD survey. We are extending this affirmative defense for any party that participates in the national survey program to help establish a defense against downstream diesel sulfur, gasoline sulfur, gasoline RVP, and E15 misfueling violations in part 1090. We believe that parties that are part of the ULSD distribution system that participate in the part 80 ULSD survey program would continue to participate in the national survey program as well as other parties in the gasoline distribution system that wish to use the survey to help establish affirmative defenses against downstream violations.

Under the E15 partial waivers and E15 substantially similar determination, fuel and fuel additive manufacturers that make E15 or ethanol for use in making E15 must participate in a compliance survey that ensures that E15 pump dispensers are labeled appropriately.[97] The E15 partial waiver conditions provide fuel and fuel additive manufacturers two options to satisfy the compliance survey condition: (1) A geographically-focused survey; or (2) a national survey. Under part 1090, we are proposing that participation in the national survey program would satisfy the national survey option for purposes of compliance with the E15 waiver conditions. The E15 waiver conditions would allow E15 fuel and fuel additive manufacturers to continue using a geographically-focused option instead if they so desired, and part 1090 includes provisions to facilitate such a program. However, we expect that fuel and fuel additive manufacturers would elect to participate in the national survey program due to significant amount of cost savings associated with participating in it.

c. Sample Sizes

We are proposing that the national survey program collect, at a minimum, gasoline samples from 5,000 gasoline retail outlets and 2,000 diesel retail outlets. Since most retail outlets offer both gasoline and diesel fuel, we believe that the total number of retail outlets sampled would be closer to 5,000 retail outlets rather than 7,000 outlets. This proposed total would be substantially lower than the current regulatory program, which requires sampling for approximately 17,000 retail outlets. We selected the number of retail outlets for gasoline and diesel based on the recent sample size determinations of the existing part 80 survey programs and we are proposing the same sample size determination methodology that is used for the existing part 80 survey programs. This results in approximately 5,000 retail outlets since the existing survey program for E15 misfueling mitigation is national in scope. Since we are consolidating the four existing programs into a national program, the statistical rigor of the sample selection methodology is unchanged and would result in the same sample size. What is different for this proposed program compared to the E15 survey program is the types of fuel samples the independent surveyor would collect at retail outlets and parameters that are tested for those fuel samples once collected (discussed more in Section X.A.2.d).

For the subset of gasoline samples that would continue to be tested for the full suite of Complex Model fuel parameters, we are proposing that the sample size would be determined using a standard calculation to estimate national fuel parameters. We expect that around 1,200 gasoline samples would be analyzed for the full suite of Complex Model fuel parameters using this methodology. We seek comment on the proposed sample size and sample size determination methodology.

d. Requirements for Independent Surveyors

We are retaining and transferring certain existing requirements for independent surveyors in part 80 to part 1090. These include the requirement that an independent surveyor would need to conduct the national survey program and meet similar independence requirements from parties that hire the surveyor to conduct the program. The independent surveyor would not be allowed to have financial interest in companies that hire the independent surveyor to conduct a survey, nor would companies be allowed to have an interest in the independent surveyor's organization. Like the part 80 survey programs, the surveyor would need to submit an annual plan for surveys conducted under part 1090. The plan would identify how the independent surveyor intends to meet the proposed regulatory requirements and would be subject to EPA approval prior to conducting the survey. Additionally, the independent surveyor would need to submit annually to EPA proof that the national survey program has been fully funded for the next compliance period by December 15.

As part of our effort to modernize the fuel quality programs, we are proposing to require that independent surveyors register with EPA and submit periodic reports electronically to EPA, which is not currently required under the part 80 survey programs. This would help EPA more quickly provide information collected as part of the national survey program and promote greater transparency in the fuel quality program. The proposed independent surveyor reporting requirements are similar to those currently specified in part 80, and the independent surveyor would need to keep records in a similar manner. We seek comment on the requirements outlined for independent surveyors conducting the national survey program under part 1090.

B. National Sampling and Testing Oversight Program

The RFG regulations in part 80 currently require that each refiner have an independent laboratory sample and test batches of RFG unless the RFG refiner has an in-line blending waiver. Refiners have the choice of having an independent lab sample and test 100 percent of their batches or 10 percent of their batches randomly selected. We also require that every 33rd batch of RFG collected by an independent lab be sent to EPA for analysis.[98] As part of consolidating the compliance provisions across the various gasoline and diesel fuel to create a single fuel quality program, we considered how best to ensure proper EPA oversight of the sampling and testing for fuels compliance.

During the rule development process, we received feedback that due to guidance set forth by EPA in the past on how to select the 10 percent of batches,[99] refiners needed to arrange for an independent laboratory to sample 100 percent of RFG batches made by a refinery and select the 10 percent random sample from among all those RFG batch samples. Since arranging to have an independent laboratory collect a sample is the most expensive part of the process, parties that provided feedback to us argued that this requirement is unnecessarily burdensome.

At the same time, we are proposing to no longer require the use of the Complex Model and remove various restrictions on the production and use of RFG. These proposed actions would diminish the need for the independent lab testing requirement as currently outlined in the part 80 RFG regulations. However, we believe that continuing to ensure that appropriate sampling and testing is conducted for fuels compliance demonstration is an important element of any streamlined fuel quality program.

Consequently, in lieu of the existing RFG requirements, we are proposing provisions for a voluntary national sampling oversight program designed to ensure that samples are collected in a consistent manner by gasoline manufacturers. The purpose of this proposed program is to help ensure that fuel manufacturers are sampling and testing in a manner consistent with required procedures, as discussed in more detail in Section IX.

As part of the proposed voluntary national sampling oversight program, we are also proposing to require that the independent surveyor review appropriate PBMS qualification and statistical quality control (SQC) data for the samples collected and tested as part of the proposed sampling oversight program. We believe that this would help ensure that labs that test gasoline for compliance under our fuel quality programs are complying with EPA quality control provisions for labs.

During the rule development process, we discussed whether a review of all PBMS qualification and SQC data as part of the annual attest audit would be appropriate.[100] In response, stakeholders suggested that auditors, many of whom lack the technical expertise to review lab quality control data, would be unable to perform such auditing functions for each lab on an annual basis, especially before the June 1 annual deadline to complete the attest audit process. These stakeholders suggested that in many cases there would be too much SQC data across an entire compliance period for auditors to reasonably review. Due to the expertise needed to review lab PBMS and SQC information and the amount of information needed to review, we believe a limited review by the independent survey as part of the proposed voluntary national sampling oversight program is appropriate. Independent surveyors must demonstrate technical competency to EPA as part of the annual plan approval process and should be familiar with EPA quality control procedures. Additionally, we are proposing a basic record review requirement as part of the attest engagement process, discussed in more detail in Section XII.B. Combined, we believe these two proposed requirements would help ensure that labs are meeting EPA's PBMS and SQC requirements.

During the rule development process, we also received feedback arguing that a voluntary national sampling oversight program would not be necessary due to SQC measures imposed on labs that test fuel samples in the Tier 3 gasoline sulfur rule. We disagree with the view that Tier 3 SQC provisions serve the same function as the national sampling oversight program. The SQC provisions place certain control measures on the actual testing by the labs of gasoline and diesel fuel samples to help ensure valid measurements. However, the SQC provisions do not address whether the sample was collected appropriately. Inappropriate sampling can affect the validity of test results regardless of whether the SQC provisions show the lab is testing appropriately. Additionally, EPA enforcement personnel have identified several issues with sampling during past audits of fuel testing laboratories that we believe can be reduced by a national sampling oversight program.

Like the national survey program described in Section X.A, we believe there is an opportunity to reduce the overall cost of sampling oversight while expanding the scope from just RFG to all gasoline nationwide. Taken together, we are proposing to require an estimated 300-400 samples would be collected as part of this proposed national sampling oversight program annually. This compares to the several thousand samples currently collected from RFG refiners each year. These samples would be spread across all gasoline manufacturers instead of just RFG refiners. We believe this is a substantial reduction in associated burden with independent sampling while still providing the necessary oversight.

We are proposing to require gasoline manufacturers that elect to account for oxygenate added downstream to participate in the proposed national sampling oversight program. We believe this requirement would help ensure that fuel manufacturers are sampling, testing, and reporting results of gasoline that is representative of gasoline (i.e., BOB) leaving the refinery gate. We are also proposing to exempt refineries that have in-line blending waivers from the national sampling oversight program since these refineries already have an annual audit requirement by an independent auditor.

Gasoline manufacturers that participate in the program would need to arrange for a sample to be overseen by an independent surveyor for each season (winter and summer). This would mean that, as long as a gasoline manufacturer has product available for testing, the gasoline manufacturer would have at least two samples collected per year. We are also proposing that an additional number of random samples be collected to ensure an effective deterrent against complacency for parties that have samples collected early in a season. For example, if we only required sampling once per season and a gasoline manufacturer had a winter sample surveyed in January of a compliance period, that gasoline manufacturer would not be surveyed in the winter for the rest of the compliance period. Additional random sampling would help ensure that gasoline manufacturers are following appropriate sampling and testing procedures year-round, even if sampled early in the season.

During the rule development process, we received feedback stating that having an independent surveyor collect a sample without advanced notice would pose a safety hazard and encounter logistical challenges that would inhibit the independent surveyor's ability to collect a sample. For example, refineries and import facilities would often not have product available for sampling, which would create an issue for an independent surveyor showing up at random to collect at a refinery. We believe that an independent surveyor should provide the minimal amount of advanced notice as practical to ensure that product is available for sampling and that the independent surveyor could observe whether samples are collected in accordance with specified sampling procedures. We also believe that since each gasoline manufacturing facility is different, the independent surveyor would need to tailor the advanced notification procedures for each facility. Specifying a procedure for every gasoline manufacturing facility would not be practical given the breadth of specific situations, so we are proposing that the independent surveyor would need to address advanced notification in its annual plan. We seek comment on ways to minimize advanced notification for the national sampling oversight program.

We also received feedback from stakeholders that suggested that replacing the RFG independent laboratory testing program with the proposed voluntary national sampling oversight program would allow for parties to more easily arrange for favorable test results that demonstrated a fuel met EPA fuel quality standards. These stakeholders suggested that having a requirement that RFG refiners specify a registered independent laboratory for testing would make it more difficult for RFG refiners to arrange for multiple laboratories to test separate samples from a single batch in search of a favorable test result. These stakeholders suggested that EPA propose to expand the RFG independent laboratory requirement to include CG refiners in addition to RFG refiners under part 1090. They suggested that we require that all third-party laboratories register and that gasoline refiners be limited to using a specified, registered third-party laboratory. While we believe that such a proposal would greatly increase the burden associated with third-party laboratory testing, which would largely fall on smaller gasoline refiners as they typically do not have their own testing laboratories, we do believe it could be useful to limit the multiple testing of a single batch by multiple laboratories to help ensure a level playing and better ensure fuel quality. Therefore, we seek comment on whether we should require that all third-party laboratories register and that refiners be limited to using a specified, registered third-party laboratory.

Historically, EPA's National Vehicle and Fuel Emissions Laboratory (NVFEL) has played a role in the development and quality control of analytical test methods used to determine compliance with our fuel quality standards. Under part 80, as part of the RFG program, NVFEL receives several hundred oversight samples from RFG refiners and independent laboratories. NVFEL analyzes these samples and compares the results to results from RFG refiners and independent labs.[101] Under part 1090, we would no longer collect these oversight samples from RFG refiners and independent labs. However, as part of the national sampling oversight program, we are proposing that the independent surveyor would send a random selection of samples collected as part of the proposed oversight program to NVFEL for comparison to the results obtained from the independent surveyor and fuel manufacturer's lab. This would allow our lab to continue to serve as a reference installation and maintain our oversight of the national sampling oversight program.

Like the proposed national survey program, we are proposing that an independent surveyor would conduct the national sampling oversight program. We envision that these parties would function similar to the way that independent surveyors operate under the existing part 80 program. Therefore, we are proposing a similar independence and plan approval process as those used for independent surveyors under part 80 and the proposed national survey program. The only difference would be a change in the reported elements as samples are collected from gasoline manufacturing facilities instead of retail stations. We seek comment on whether the approach outlined for independent surveyors is appropriate for the national sampling oversight program.

We seek comment on all aspects regarding the proposed national sampling oversight program.

XI. Import of Fuels, Fuel Additives, and Blendstocks

We are transferring most of the current provisions in part 80 that address the importation and exportation of fuels, fuel additives, and blendstocks to part 1090 (subpart P). As described in this section, importers would continue to be subject to the same requirements as refiners, while exporters would continue to be subject to certain fuel designation and recordkeeping provisions. Overall, we are proposing few changes to how imported and exported fuel products are treated relative to the current provisions of part 80, although we are proposing to significantly change the regulatory text. Many of the proposed provisions are merely codification of existing implementation policies summarized in a 2003 question and answer (Q&A) document (“2003 Q&A”).[102]

A. Importation

With few exceptions, we are proposing requirements for importers that largely mirror what we currently require under part 80. However, we are proposing some updates to provisions for imports. First, under part 1090, importers that import fuel at multiple import facilities within a single PADD would need to aggregate the facilities for purposes of complying with the benzene maximum average standard. For compliance with other average standards, importers would continue to comply at the company level. Batches of imported fuel that are subject to certification requirements must be certified separately for U.S. Customs Service purposes at each U.S. port of entry.[103]

Second, under part 80, we currently have guidance that allows gasoline classified as “American Goods Returned” to the United States by the U.S. Customs Service to not count as imported gasoline.[104] We are proposing language consistent with that guidance in part 1090, provided all the following conditions are met:

  • The gasoline was produced at a fuel manufacturing facility located within the U.S. and has not been mixed with gasoline produced at a fuel manufacturing facility located outside the U.S.
  • The gasoline must be included in compliance calculations by the producing manufacturer.
  • All the gasoline that was exported must ultimately be classified as American Goods Returned to the United States and none may be used in a foreign country.
  • No gasoline classified as American Goods Returned to the United States may be combined with any gasoline produced at a foreign refinery prior to being imported into the U.S.

We are not making any significant changes to the definition of an importer, which we define as “a person who imports gasoline, gasoline blendstocks or components, or diesel fuel from a foreign country into the United States (including the Commonwealth of Puerto Rico, the Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands).” The importer under part 1090 would generally be the importer of record under the Bureau of Customs and Border Protection regulations. This would typically be the entity that owns the fuel, fuel additive, or regulated blendstock when the import vessel arrives at the U.S. port of entry, or the entity that owns the fuel, fuel additive, or regulated blendstock after it has been discharged by the import vessel into a shore tank. We seek comment on these proposed updates to the import provisions under part 1090, and whether we should make changes to the definition of an importer.

B. Special Provisions for Importation by Rail or Truck

We are proposing reduced compliance options for meeting testing requirements when importing fuels by either rail or truck. These provisions would allow importers to meet the sampling and testing requirements based on test results from the supplier instead of testing each batch after the fuel was imported under certain conditions.

First, the importer would need to get documentation of test results from the supplier for each batch of fuel. Testing for a given batch would need to occur after the most recent delivery into the supplier's storage tank and before transferring product to the railcar or truck.

Second, the importer would need to conduct testing to verify test results from each supplier, by collecting samples either once every 30 days or every 50 rail or truckloads from a given supplier, whichever is most frequent. The proposed provisions would treat importation of gasoline and diesel fuel separately but apply to rail and truckloads together if the importer imported product from a given supplier by rail and truck.

C. Special Provisions for Importation by Marine Vessel

We are proposing provisions that specifically address importation of fuels by marine vessels. These provisions are generally the same as those addressed in the 2003 Q&A. Under part 1090, separate certification would be required at each import facility, unless the fuel is transported by the same vessel making multiple stops but does not pick up additional fuel. Consistent with the current part 80 requirements, we are proposing not to allow importers who import by marine vessels to rely on testing from a foreign source.

Additionally, testing may not be based on samples collected after the fuel is off-loaded, unless certain conditions are met that are designed to make sure the imported gasoline meets all per-gallon standards and that compliance reports accurately reflect the sulfur and benzene content of the imported fuel.

Under these proposed provisions, when finalized, different ship compartments would be considered different batches of fuel. However, we are proposing the following exceptions. First, importers would be allowed to treat the fuel in different compartments of a ship as a single batch if they demonstrate that the fuel is homogeneous across the compartments as proposed for all composite samples. As is the case under part 80, importers would need to demonstrate that results for homogeneity testing fell within the specified repeatability range for the test method used(s) used to determine homogeneity. Under the updated homogeneity testing procedures in part 1090, this would result in a decrease in the amount of analytical testing needed to establish homogeneity for combining marine vessel compartments compared to part 80. This decrease in testing is mostly a result of part 80 requiring that importers establish homogeneity for all Complex Model parameters, which could be as many as 11 fuel parameters. Under part 1090, importers would only need to establish homogeneity for two fuel parameters. This change would result in a substantial decrease in testing burden.

Second, we would also accept the analysis of samples collected from different ship compartments that are combined into a single volume-weighted composite sample if the compartments are off-loaded into a single shore tank, or each individual vessel compartment is shown, through sampling and testing, to meet all applicable standards.

D. Gasoline and Diesel Fuel Treated as Blendstocks

We are largely transferring current provisions for Gasoline treated as Blendstocks (GTAB) in part 80 to part 1090. We are also proposing to substantially reduce the number of parameters that are tested and reported to EPA. Our primary concern with GTAB has been to ensure that off-spec gasoline imported into the U.S. are properly blended to produce gasoline that meets applicable fuel quality standards. When initially established under the RFG and Anti-dumping programs, the GTAB provisions focused on the entire set of parameters needed to run the Complex Model. Since compliance with our fuel quality standards is based on sampling and testing the finished fuel and part 1090 would no longer require certification of batches of gasoline using the Complex Model, we believe that the testing and reporting of fuel parameters for GTAB is no longer necessary. However, volumes for batches of GTAB would continue to need to be reported. Other proposed provisions related to GTAB are consistent with current part 80 requirements and published guidance.

We are also proposing to replace the existing part 80 requirements for diesel treated as blendstock (DTAB) with a simplified procedure. Under part 80, most of the DTAB provisions are designed to account for the DTAB in compliance calculations that have not been used since 2010. The part 80 provisions require importers to include DTAB in compliance calculations that are no longer applicable, to keep DTAB segregated from other diesel fuel, and limit the importer's ability to transfer title of DTAB. Under part 1090, importers would be able to import diesel fuel that does not meet applicable EPA standards if the importer offloads the imported diesel fuel into one or more shore tanks containing diesel and then samples and tests the blended fuel to confirm that it meets all applicable per-gallon standards before introduction into commerce. We believe this process greatly simplifies the certification process for DTAB and seek comment on this approach.

XII. Compliance and Enforcement Provisions and Attest Engagements

A. Compliance and Enforcement Provisions

We are also transferring compliance and enforcement provisions, such as liability, penalty, and prohibited acts and affirmative defense provisions that are currently in part 80 to part 1090. We are however, revising existing regulatory text by providing them in an easier to understand format.[105] We are proposing regulatory text that consolidates and eliminates multiple prohibited acts statements in part 80 and replacing them with a simple statement that “[a]ny person who violates any requirement in this part is liable for the violation.” We solicit comment as to whether this proposed statement will address the universe of regulatory provisions in part 1090.

We are also seeking comment on the appropriate default value that would be applicable to sampling and testing requirements violations for fuel content standards. The existing requirements for regulated parties to accurately sample and test fuels are one of the lynchpins of our fuel quality regulations. If regulated parties fail to properly sample and test fuel, it makes is difficult for EPA and the public to know if the fuel meets the applicable standards. Unlike in the case of our vehicle and engine regulations where the vehicles and engines still exist and can be tested by EPA to verify compliance, in the case of fuel, it is typically commingled with other fuel in the distribution system immediately upon production, and quickly consumed. The existing part 80 regulations provide that if a refiner or importer fails to comply with the gasoline sampling and testing requirements, the gasoline will be deemed to have a sulfur content of 970 ppm, a benzene content of 5 volume percent, and a summer RVP of 11 psi, unless the respective party or EPA demonstrates by reasonably specific showings, by direct or circumstantial evidence, different properties for the gasoline giving rise to the violations.[106] This creates an additional incentive for refiners and importers to properly sample and test gasoline and ensures that that they will not benefit by underreporting the sulfur, benzene, and/or RVP of gasoline that is not properly sampled or tested. However, during the rule development process, several stakeholders requested that we reconsider the default values that EPA uses for enforcement when a regulated party lacks a valid test result for a regulated fuel parameter.

We are not proposing any revisions to the default values currently found in part 80. We recognize, however, that the gasoline pool today has substantially lower levels of sulfur and benzene than at the time the default values were promulgated. For this reason, we seek comment on whether to establish lower default values for these parameters, and what an appropriate default value should be. We are also proposing default values for regulated parameters for fuels, fuel additives, and regulated blendstocks where we do not have existing default values in part 80 for parties that fail to meet the applicable sampling and testing requirements. Table XII.A-1 lists the proposed default values.

Open Table

Table XII.A-1—Proposed Default Values for Fuel, Fuel Additive, and Regulated Blendstock Parameters

Product Sulfur value (ppm) Benzene value (volume percent) RVP value (psi)
Gasoline 970 5 11
PCG (by subtraction) 0 0 n/a
Diesel Fuel 1,000 n/a n/a
ECA Marine Fuel 5,000 n/a n/a
Fuel Additives 970 n/a n/a
Regulated Blendstocks 970 5 n/a

In general, for fuel additives and regulated blendstocks, we are proposing default values consistent with the existing values for gasoline, as we believe these products have similar potential for high sulfur levels that would be found in the production of gasoline. During the rule development process, some stakeholders pointed out the use of default values by blender manufacturers who use PCG by subtraction could result in the inappropriate generation of sulfur and benzene credits. Since the main purpose of these default values is to provide incentives for parties to obtain valid test results, our proposal to assume zero sulfur and benzene content from the PCG in a PCG by subtraction scenario would attribute all sulfur and benzene to the added blendstock and provide incentives for a blending manufacturer to appropriately sample and test the PCG.

For diesel fuel, we are proposing a default 1,000 ppm sulfur value, as this level of sulfur content is consistent with the distillate ECA marine fuel specification. For ECA marine fuel, we are proposing a default 5,000 ppm sulfur value, as this level of sulfur content is consistent with global marine fuel standards to meet the 2020 MARPOL Annex VI marine fuel sulfur specification. For both diesel fuel and ECA marine fuel, we expect that the next higher sulfur standard provides a logical default value and would provide incentives for diesel fuel and ECA marine fuel manufacturers to obtain valid test results.

We seek comment on the newly proposed default values. When providing comments related to the proposed default values, commenters should provide a thorough rationale (including relevant data and information) for suggested default values to help EPA consider alternative default values.

We are not proposing any other significant revisions to current compliance and enforcement provisions that are in part 80. As earlier explained, we are merely consolidating and simplifying these provisions in part 1090. We will treat comments on any other compliance and enforcement provisions beyond those discussed in this section as outside of the scope of this action.

B. Attest Engagements

Part 80 includes a requirement for gasoline refiners and importers to engage auditors to review information reported to EPA. These annual attest engagements allow EPA to more effectively ensure compliance with regulatory requirements.

We are transferring existing attest requirements in part 80 to a single subpart in part 1090 (subpart R). We are removing obsolete material, updating the language for improved clarity, and making some minor adjustments and clarifications to improve the quality and consistency of reported information.

For instance, we are proposing to add a requirement for auditors to review the refiner's or importer's calculations showing that they comply with the sulfur and benzene average standards. We note that the EPA's Office of Inspector General made certain findings regarding compliance with these standards and recommendation as part of their review of the auditing requirements under part 80.[107] One recommendation was to modify the attest engagement regulations to require that attest auditors verify compliance calculations for gasoline manufacturers to help ensure that the average benzene standard was met. We believe the proposed attest engagement provisions are consistent with this recommendation and would provide better oversight of the gasoline sulfur and benzene average standards.

We are also proposing to codify the existing attest requirements spelled out in the RFG Q&A document.[108] We are proposing these requirements for both CG and RFG. The most significant proposal would be the requirement for auditors to review PBMS qualification and SQC records related to the sampling and testing requirements for gasoline on an annual basis. We are proposing to require a relatively straight-forward review by auditors of whether labs used to test gasoline for compliance have records demonstrating that methods have been qualified under the PBMS qualification requirements and that the lab is maintaining SQC records. It is worth noting that we are not proposing to require auditors to interpret this information as auditors may lack the appropriate technical expertise to interpret lab data for conformance with PBMS and SQC requirements. Instead, as discussed in Section X.B, we are proposing that the independent surveyor review this type of information under the voluntary sampling oversight program. We do not believe that this simple review will greatly increase the burden associated with the annual attest audits. We believe this lab record review would help ensure that labs used for testing fuels for compliance are doing so in a manner consistent with EPA's quality control requirements helping to ensure a level playing field and program integrity. We seek comment on this proposed lab record review requirement and other aspects of the streamlined attest engagement requirements. We are also seeking as to whether there are other requirements that would be implemented for purposes of providing adequate annual attest audits.

C. RVP Test Enforcement Tolerance

Currently, the agency recognizes and allows a 0.3 psi downstream enforcement test tolerance over applicable RVP standards for RVP test results.[109] This test tolerance was based on RVP testing variability and the reproducibility of the test methods. Under this approach, we rely on test results from locations downstream of refineries or import facilities to bring enforcement actions against downstream parties only if the downstream test results are more than 0.3 psi than the applicable standard. Although any sample that is over the standard is a violation, we generally do not bring enforcement actions against a downstream party if the sample it collects is over the standard but within the 0.3 psi enforcement test tolerance, as long as there is no reason to believe that the downstream party caused the gasoline to exceed the standard. Gasoline manufacturers may not use the tolerance to effectively raise the applicable standard. If the refiner's or importer's test results show the gasoline exceeds the RVP standard, then the gasoline is in violation regardless of whether or not the RVP test result is within the tolerance.

At this time, we intend to continue this same RVP enforcement test tolerance policy to enforce the gasoline volatility standards in part 1090. Under part 1090, the 0.3-psi RVP tolerance would apply to both summer CG and summer RFG. However, as before, we may change this enforcement policy at any time, including adopting new tolerances as data on test methods are developed, as technology changes, or as further information becomes available concerning the precision of RVP test methods.

XIII. Other Requirements and Provisions

A. Requirements for Independent Parties

We are proposing requirements for third parties performing actions authorized under part 1090 regarding their independence from the regulated parties who engage them and their technical qualifications. These proposed requirements would be consistent with part 80 independence and technical competency requirements for independent third-parties. We believe the proposed requirements would preserve and strengthen the integrity of our independent third-party verification programs.

We have always had concerns about the potential for conflicts of interest between the independent third-parties that monitor compliance on behalf of EPA and the regulated entities who engage them and are proposing the same independence requirements for third-parties as currently used in part 80. In addition, since proposing the original independence requirements for third-parties under the RFG and Anti-dumping programs in the 1990s, we have seen that third-parties often employ contractors or subcontractors to fulfill third-party oversight requirements. These contractors or subcontractors should also be free from conflicts of interest from regulated parties for whom services are performed. Therefore, we are proposing to clarify that independence requirements apply not only for the third parties and their employees, but also for any contractors and subcontractors.

Similar to part 80 provisions, we are proposing to impose restrictions on both employment history and financial interest. We are proposing that independent third parties would be required to ensure that their employees, contractors, and subcontractors had not worked for the regulated party that hired that third party for any amount of time over the previous three years. While the financial independence requirements imposed on the independent third party's employees, who are directly involved in overseeing the regulated parties, prohibiting them from owning or otherwise having any financial interest in that regulated party are generally not changing, we are proposing to apply these existing independence requirements at the contactor and subcontractor levels. There would also be a limitation imposed on the independent third party's firm or organization as to the proportion of revenue it can generate from any single regulated party. We believe this furthers our goal of independent third-party oversight and increases the trustworthiness of the program's results. We seek comment on these independence requirements and their impacts on the independent third parties, as well as the anticipated effectiveness of these provisions to increase reliability in our third-party oversight program.

Part 1090 also proposed to include requirements on the technical qualifications of the independent third parties. We have employed similar requirements under part 80 and have used these requirements in other cases where technical competency is important to conduct regulated activities for a regulated party; however, we do not currently require this demonstration for in-use surveys.[110] These provisions will ensure that program oversight is being conducted by parties with the requisite technical capabilities. We are proposing to require that the independent surveyors, which are regulated further under subpart N, employ personnel with expertise in the areas of petroleum marketing, sampling and testing fuels at retail stations, and survey design. Technical competency requirements for attest engagement auditors and independent laboratories that qualify alternative test procedures under PBMS would be unchanged in part 1090.

We request comment on these technical and experience requirements and their impacts on the third party oversight program.

B. Labeling

Part 1090 includes provisions that apply specifically to retailers and WPCs, consolidating the various provisions formerly scattered throughout part 80 (including the whole set of fuel pump labeling requirements) into one subpart (subpart O) with only minor changes (including removing several obsolete provisions from part 80). We are further proposing to streamline the description of the E15 label by replacing descriptive paragraphs with a graphic example of the E15 pump label. We believe these changes would make the regulations easier to identify and follow for retailers and WPCs.

We are proposing minor modifications to the existing label language. For heating oil, we are proposing to remove the label language identifying that heating oil contains greater than 500 ppm sulfur.[111] Most heating oil sold today meets state 15 ppm sulfur standards, and we believe that it is misleading and inappropriate to require that heating oil dispensers label their product as having greater than 500 ppm sulfur. To minimize burden on retailers, we are proposing that retailers could use existing labels to satisfy the part 1090 labeling requirements and that retailers would need to affix a heating oil label compliant with the part 1090 label requirements when the existing part 80 label needs replacement.

During the rule development process, we received feedback from stakeholders suggesting that the ECA marine fuel labels were no longer necessary due to the way that ECA marine fuel is sold and dispensed for use in Category 3 marine vessels. Another option would be to limit labeling to situations where ECA marine fuel is co-dispensed with other fuels since the purpose of the ECA marine fuel label is to help avoid the misfueling of diesel engines that require the use of ULSD with ECA marine fuel. This would only be an issue where such diesel engines could reasonably be misfueled (i.e., in situations where both ECA marine fuel or ULSD are co-dispensed). While we are proposing to maintain the ECA marine fuel labels currently required under part 80, we seek comment on whether maintaining these labels is necessary or whether we could limit the use of the label to only situations where ECA marine fuel is co-dispensed with other fuels.

We also seek comment on the structure of proposed fuel pump labeling regulations, and on the various modifications to label content described in this section.

C. Refueling Hardware Requirements for Dispensing Facilities and Motor Vehicles

As described in the preceding section, part 1090 includes a subpart devoted to requirements for retailers and WPCs. This subpart also describes requirements related to refueling hardware.

The proposed nozzle requirements for refueling motor vehicles are aligned with the requirements adopted under part 80. There is one noteworthy adjustment. We are proposing to identify nozzle specifications only in millimeters. The parallel metric and English units in part 80 are nearly identical, but this nevertheless creates two separate sets of requirements, which is contrary to the objective of standardizing hardware. The specifications in part 80 also include a level of precision that is greater than is needed to properly identify a standard configuration. The single set of specifications, including rounding, is consistent with the specifications in part 80, so the updated nozzle specifications should not cause any existing hardware to be noncompliant, and any existing blueprints for producing nozzles would not need to be modified.

Similar nozzle requirements apply for dispensing gasoline into marine vessels. We are similarly proposing a singular set of nozzle-geometry specifications in millimeters in a way that is aligned with the specifications as originally adopted. We are also proposing to finish the allowed phase-in of these nozzle-geometry specifications. As originally adopted, the nozzle requirements applied as of January 1, 2009, to new installations and to new nozzles used to repair or replace damaged dispensing equipment. Based on industry feedback, the market has now transitioned, so there is no need for our regulations to continue to allow non-standard nozzles. If there are any remaining nozzles for marine refueling that do not meet specifications, we are proposing to require that they be replaced with a nozzle that meets the standardized configuration. The requirement would apply January 1, 2021, when part 1090 becomes effective. We request comment on the timing of this proposed requirement, and on the extent of modification that is required for all installations to meet the nozzle-geometry requirements.

Part 80 additionally specifies a standardized geometry for filler necks in light-duty and heavy-duty motor vehicles to correspond with the nozzle geometry specifications. We are proposing to move these vehicle-based requirements to 40 CFR parts 86 and 1037, which describe standards and other requirements for light-duty and heavy-duty motor vehicles.

D. Previously Certified Gasoline (PCG)

We are proposing to largely maintain the existing part 80 provisions for how blending manufacturers may make new batches of gasoline from PCG and blendstocks.[112] In the Tier 3 rule, we finalized changes to improve the consistency of the PCG provisions across part 80; [113] however, we maintained separate PCG provisions for each part 80 gasoline program. In part 1090 we are proposing to consolidate these provisions into a single set of PCG provision. The proposed PCG provisions maintain both options used in part 80: (1) PCG by subtraction and (2) PCG by addition.[114] Other proposed changes are minor and designed to improve clarity and consistency of the PCG provisions in part 1090. Other provisions related to blending certified butane or certified pentane are discussed in Section V.A.3. We seek comment on the proposed consolidation of the PCG provisions.

E. Transmix and Pipeline Interface Provisions

In part 1090 we are consolidating and simplifying the flexibilities provided to fuel manufacturers that use transmix to produce gasoline and diesel fuel. We are also proposing changes to align the requirements applicable to these parties to the requirements applicable to fuel manufactures under part 1090.[115] Some of the part 80 regulations characterize the requirements for transmix processors and transmix blenders as alternative compliance mechanisms. For instance, the gasoline sulfur regulations state that ”[t]ransmix processors and transmix blenders may comply with the following sampling and testing requirements and standards instead of the sampling and testing requirements and standards otherwise applicable to a refiner under this subpart O.” [116] The part 1090 regulations set forth specific requirements for transmix processors and transmix blenders because we believe that virtually all transmix processors and blenders are using the alternative approaches set forth in part 80, and because we believe that it would be overly complex for transmix processors and blenders to comply with the requirements that apply to other fuel manufacturers. We seek comment on whether transmix processors and blenders should have the option to comply with the requirements that apply to other fuel manufacturers. Any comment on this issue should provide specific recommendations regarding how to structure the program to assure compliance with all per-gallon standards, accurately account for the sulfur and benzene content of the fuel, and avoid double counting. These proposed changes to the transmix rules are discussed in the following sections.

1. Clarifying and Consolidating the Definitions of Transmix and Pipeline Interface

Part 80 currently provides flexibilities for transmix due to the unique way in which transmix is reprocessed into useable products and the need to expeditiously clear transmix volumes from the fuel distribution system to keep product flowing to markets. Transmix has traditionally been processed at small facilities that cannot support the installation of fuel desulfurization equipment. For example, pipelines are permitted to blend limited volumes of transmix into fuels subject to EPA standards provided that such blending does not impact compliance with the standards. Part 80 also provides that 500 ppm diesel fuel from transmix processors can be sold for use in older locomotive and marine engines that do not require the use of 15 ppm diesel fuel. Other diesel fuel producers are required to meet 15 ppm sulfur standard for all LM diesel fuel they produce. Transmix processors that produce 500 ppm LM diesel fuel are required to submit a compliance plan that demonstrates that the 500 ppm LM diesel fuel will not be used in engines that require the use of 15 ppm diesel fuel.

Products are commonly shipped by pipeline adjacent to each without any physical barrier between the products. Pipeline interface is defined as the volume of petroleum product generated in a pipeline between two adjacent volumes of non-identical petroleum product that consists of a mixture of the two adjacent products.[117] The pipeline interface “cut” refers to the point between the two adjacent pipeline batches where physical separations are reintroduced at the end of shipment by pipeline. Depending on the quality requirements of the adjacent products, pipeline interface can often be cut in one or both of the adjacent products. When one of the adjacent products has unique quality specifications, it is sometime necessary to cut all of the interface into the product with the less stringent specifications. In situations where the pipeline interface cannot meet the specifications for either of the adjacent batches, it is called transmix and must be segregated for further processing before being sold as a fuel. This is typically the case when batches of gasoline and diesel fuel must be shipped by pipeline adjacent to one another.

Provisions related to the treatment of transmix are currently located in various sections in part 80.[118] To improve clarity, we are consolidating most of the special provisions related to the treatment of transmix into a single subpart in part 1090 (subpart F). We are also incorporating the definitions of transmix and pipeline interface into the definitions section of part 1090. These definitions are currently imbedded in part 80 in a regulatory section that pertains to the treatment of interface and transmix.[119]

2. Blending Transmix Into Previously Certified Gasoline

In part 1090 we are proposing a minor change to the requirements that apply to parties that blend transmix into PCG.[120] When the quality assurance program required of a transmix blender indicates that the gasoline does not comply with EPA standards, blenders that use a computer controlled in-line blending system are temporarily required under part 80 to conduct more frequent sampling and testing. We are proposing that no more than one sample per day may be used to demonstrate compliance with this increased testing requirement. We believe that this is consistent with common industry practice to spread out the required samples at the proposed one per day frequency, so adoption of this proposed change would not result in an increased burden to industry. The existing part 80 regulations would allow unscrupulous parties to circumvent the intended purpose of the regulations by pulling all of the required samples at one time. This proposed change in part 1090 would ensure that the required increase in sampling and testing frequency fulfills the intended purpose of verifying that the issue that caused the violation has been resolved.

3. Gasoline Produced From Transmix Gasoline Product

Transmix gasoline product (TGP) is the distillation fraction produced by a transmix processor that is in the gasoline boiling range. Parties that produce gasoline from TGP are currently provided with streamlined provisions in part 80 to demonstrate compliance with the requirements that apply to fuel manufacturers. These current provisions are complicated by the additional fuel parameter specifications for RFG beyond those for CG. The proposed elimination of these additional requirements for RFG (discussed in Section V.A.2.c) makes these complications unnecessary since the only difference between RFG and CG would be the applicable volatility standard. Therefore, in the streamlined provisions in part 1090 we are proposing to eliminate the current differences for producing RFG versus CG from TGP and replace it with provisions consistent with the proposed streamlined provisions for gasoline.[121] Under the proposed approach, the only difference between the streamlined provisions producing RFG versus CG from TGP would pertain to the volatility standard that would apply. Under this approach, parties that use these streamlined provisions would exclude the volume of TGP and PCG used to produce gasoline from their annual compliance calculations to demonstrate compliance with the sulfur and benzene average standards under all circumstances. Parties that use only TGP or TGP and PCG to produce gasoline would be deemed in compliance with the sulfur and benzene average standards, provided they are in compliance with the proposed streamlined provisions. Parties that made gasoline with TGP and other blendstocks would use PCG procedures to account for the sulfur and benzene levels of the added blendstocks for demonstrating compliance with annual average sulfur and benzene standards. In all cases, as is the case today under part 80, parties that make gasoline using TGP would need to meet per-gallon sulfur and RVP (in the summer) standards for the resultant gasoline and make sure that the gasoline they produce meets the substantially similar requirements of the CAA.

To provide additional flexibility, we are proposing that parties who use these streamlined provisions and could demonstrate that the feedstocks they use to produce gasoline contain no oxygenate would not be required to test the gasoline they produce for oxygenate content.

4. 500 ppm LM Diesel Fuel Produced From Transmix

To improve clarity and remove restrictions that are not cost effective, we are proposing minor modifications to the regulatory provisions that allow transmix processors to produce 500 ppm LM diesel fuel for use in locomotive and marine engines that do not require the use of ULSD.

The current regulations in part 80 require facilities that handle 500 ppm LM diesel fuel to segregate it from fuel having other designations (e.g., ULSD) all the way from the producer through to the ultimate consumer.[122] Locomotive refueling facilities stated that the supply of 500 ppm LM diesel fuel is sometimes not consistent enough to ensure an adequate supply in their 500 ppm LM storage tanks that are dedicated to supplying 500 ppm LM diesel fuel. To facilitate the efficient refueling of their locomotives that may use 500 ppm LM diesel fuel, they requested that EPA allow ULSD to be introduced to their 500 ppm LM storage tanks provided that the resultant mixture of 500 ppm LM and ULSD is treated as 500 ppm LM. We agreed that providing this flexibility would be consistent with the intent of the 500 ppm LM diesel fuel segregation requirements under part 80 to ensure that the 500 ppm LM diesel fuel is not inappropriately swelled by the introduction of greater than15 ppm diesel fuel that was not produced from transmix. Accordingly, we issued guidance [123] to retail and WPCs of 500 ppm diesel fuel that ULSD may be introduced to their 500 ppm LM storage tanks provided that resultant mixture of 500 ppm LM diesel fuel and ULSD is treated as 500 ppm LM diesel fuel. We are proposing to codify this guidance in part 1090. There is thus no impact of this regulatory change, but it will improve the clarity and understanding of our regulations.

Part 80 currently requires that the volume of 500 ppm LM diesel fuel may increase by no more than 2 volume percent while in the custody of any party in the distribution system. We are proposing to remove this requirement because we believe that the other existing safeguards are sufficient to prevent an inappropriate increase in the volume of 500 ppm LM diesel fuel during distribution due to the introduction of other high sulfur distillate streams. For example, pipeline operators may only ship 500 ppm LM diesel fuel by pipeline if the fuel does not come into physical contact in the pipeline with batches of other distillate fuel that have a sulfur content greater than 15 ppm. Other parties in the distribution system are required to segregate 500 ppm LM diesel fuel from other fuels except for the allowance discussed above to introduce ULSD into retail and WPC storage tanks. All parties in the distribution system must maintain records to demonstrate that an increase in 500 ppm LM diesel fuel while in their custody was due to normal interface cutting practices, thermal expansion, and/or the addition of ULSD to retail or WPC storage tanks.

Stakeholders have also requested that regulatory language be added to clarify that ULSD may be used as a blendstock with transmix distillate product (TDP) to produce 500 ppm LM diesel fuel. They also requested that we clarify that 500 ppm LM diesel fuel may be redesignated as IMO marine fuel, heating, oil, or blendstock. We are proposing that these practices are acceptable under part 1090. We are proposing that parties that redesignate 500 ppm LM diesel fuel as IMO marine fuel would be required to maintain records from the producer of the 500 ppm LM diesel fuel (i.e., PTDs accompanying the fuel) to demonstrate compliance with the 500 ppm maximum sulfur standard.

5. Streamlining the Requirements for Pipeline Interface That Is not Transmix

The current requirements for RFG include specifications for additional fuel quality parameters beyond those required for CG. These additional requirements for RFG necessitated unique requirements related to the treatment of the interface between RFG and CG. For example, part 80 currently requires that interface containing RFG and CG must be designated as CG.[124] The proposed changes to RFG discussed in Section V.A.2 would eliminate concerns over maintaining average RFG emission performance and limit the fuel property distinction between CG and RFG to just RVP and then only during the summer months. Therefore, we are proposing to similarly streamline the provisions regarding interface cuts between RFG and CG. We are proposing that pipeline operators may cut pipeline interface from batches of RFG and CG that are shipped adjacent to each other by pipeline into either or both these gasoline batches, with fewer limitations. During the winter months there would be no restrictions remaining. Only during the summer season are we proposing that pipeline operators could not cut pipeline interface from two batches of gasoline subject to different RVP standards that are shipped adjacent to each other by pipeline into the gasoline batch that is subject to the more stringent RVP standard. For example, pipeline operators could not cut pipeline interface from a batch of RFG shipped adjacent to a batch of CG into the batch of RFG. We believe these reduced restrictions would allow greater flexibility and efficiency in the distribution of gasoline.

F. Gasoline Deposit Control

1. Overview

Section 211(l) of the CAA requires EPA to establish specifications for additives to prevent the accumulation of deposits in engines and fuel supply systems and that all gasoline contain such additives. In response to this requirement, EPA's gasoline deposit control (“detergent”) program was finalized in July 1996 and became effective in July 1997.[125] The detergent program requires that all gasoline, including the gasoline blend component of E85, contain a detergent that satisfies EPA deposit control requirements before being distributed from a petroleum terminal. Terminal operators are required to prepare and keep volumetric accounting reconciliation (VAR) records to demonstrate that a sufficient volume of detergent was added to the gasoline they distribute for each accounting period.[126]

Based on a review of emissions test data on circa 1990 vehicles and information on the levels of detergent use absent a federal detergency requirement, we estimated that the detergent program would result in roughly a 1 percent reduction in hydrocarbon and carbon monoxide emissions, a 2 percent reduction in NOX emissions, and a 0.06 percent improvement in fuel economy on average from the gasoline vehicle fleet at the time.[127] Given the considerable changes to vehicle technology and to gasoline composition since 1990 that may affect both deposit formation and its impact on emissions, and given the lack of emissions test data on the effects of deposits on emissions from modern vehicles, we are unable to quantify the emissions benefits of different levels of deposit control stringency under the detergent program today. During the rule development process, some stakeholders stated that the existing federal detergents program could affect gasoline direct injection engines in a different manner than circa 1990 vehicles. We have also been informed that there may be situations where the presence of a detergent may not provide any benefit and may actually exacerbate deposit formation. Given the paucity of data on the current effects of the detergent program in the modern vehicle fleet, we seek comment on information on the effects of the federal detergent program on controlling deposits in modern vehicles and the impact on vehicle emission performance.

At the same time, there is considerable cost and effort associated with continuing to implement the detergent program. Consequently, we are proposing to streamline the program to the extent possible to minimize its cost. Specifically, we are proposing to: (1) Eliminate the redundant requirement that a detergent that is demonstrated to control intake valve deposits also be tested to demonstrate the ability to control fuel injector deposits; (2) ease the adoption of updated deposit control test procedures when they become available; (3) simplify the process for registration and certification of detergents and the demonstration of compliance by detergent blenders; (4) remove expired and unused provisions; and (5) remove the requirement that the gasoline portion of E85 must contain a certified detergent. The following sections detail the changes we are proposing.

CAA section 211(l) includes a requirement that gasoline must “contain additives to prevent the accumulation of deposits in engines or fuel supply systems.” Our regulations maintain this requirement, but we are proposing to modify or eliminate certain testing requirements and simplify the registration and certification process and compliance demonstrations. CAA section 211(l) also requires that EPA promulgate regulations with specifications for detergents. While this action modifies those specifications, it maintains the requirement that gasoline contain detergents and maintains specifications for detergents, updating them to accommodate new circumstances discussed in this section. These proposed changes to the detergent program continue to be compliant with CAA section 211(l).

2. Eliminating the Port Fuel Injector Deposit Control Testing Requirement

We are proposing to eliminate the requirement that detergents be tested to demonstrate the ability to control port fuel injector deposits. This would substantially decrease the burden of introducing new detergents while maintaining the benefits of the detergent program.

We currently require separate tests to demonstrate the ability of a detergent to control port fuel injector deposits and intake valve deposits. Input from stakeholders during the rule development process supports the conclusion that detergents that are capable of controlling intake valve deposits are inherently capable of controlling port fuel injector deposits.[128] This conclusion is also supported by the elimination of a port fuel injector testing requirement in the industry-based Top Tier detergency program. The Top Tier program was established by industry based on the premise that a superior level of deposit control was needed for today's vehicles than that provided by EPA requirements. Further support is evidenced by the lack of industry activity to have a separate test for port fuel injector deposits. The port fuel injector deposit control test required by EPA is based on the ASTM D5598 fuel injector deposit control test procedure that uses a 1985-1987 Chrysler 2.2L vehicle.[129] The fuel injector technology used in these antiquated test vehicles is no longer representative of technology used in the current vehicle fleet. Current industry efforts are focused on developing an updated intake valve deposit (IVD) control test procedure and the evaluation of deposit control in gasoline direct injection engines that represent an increasing share of the new vehicle fleet.

3. Amending the Intake Valve Deposit Control Test Procedures

Like the port fuel injector test procedure, the intake valve test procedure in our regulations is likewise antiquated and of questionable relevance to the in-use fleet today. New detergents are currently tested using the EPA ASTM D5500 BMW-based deposit control test procedure (“EPA ASTM D5500 procedure”) procedure, which uses a 1985 BMW 318i vehicle. This vehicle was accepted as representative of technology in the vehicle fleet when the detergent program was finalized in 1996. However, this 34-year-old vehicle is no longer representative of the technology used in modern vehicles.[130] It is also increasingly difficult for emissions laboratories to perform the EPA ASTM D5500 procedure due to the deterioration of the aged test vehicles and the lack of replacement parts. Consequently, CRC is currently developing an updated deposit control test procedure.[131]

In addition, the test fuel specified by EPA for use in the ASTM D5500 procedure is no longer representative of current gasoline. The composition of the requisite test fuel is specified to assure a 65th percentile concentration of gasoline parameters that affect deposit formation based on 1990 gasoline survey data.[132] The composition of gasoline in the U.S. has changed significantly since 1990 due to EPA fuel quality requirements and changes in refinery operations due to the widespread use of E10. These changes to gasoline composition have resulted in current in-use gasoline having a different deposit-forming tendency compared to the 1990 gasoline on which the test fuel specifications are based. The Tier 2 gasoline sulfur program, finalized in 2000, reduced the sulfur content of gasoline by up to 90 percent.[133] The Tier 3 gasoline sulfur program, finalized in 2014, required a further reduction in gasoline sulfur levels to a 10 ppm average from a 30 ppm average under the Tier 2 program.[134] Parties that formulate detergent test fuels stated that the more stringent gasoline sulfur requirements were making it impossible to make the sufficiently stringent test fuels using only normal refinery blendstocks or finished gasoline. As a result, we issued guidance that a sulfur doping compound could be used to meet the minimum test fuel sulfur specification for test purposes, even though such fuels no longer exist in-use.[135]

Consequently, we no longer have confidence that the current EPA ASTM D5500 procedure can be used to assess deposits in today's vehicle fleet and therefore that the detergent additives tested using it provide any of the real world emission benefits quantified in 1996 when the detergent regulations were finalized. As a result, we are proposing to streamline our intake valve deposit control requirements. Specifically, we are proposing that new detergent deposit control testing would be conducted using California's deposit control program or the Top Tier program.[136] Data from California's program is currently accepted to satisfy EPA requirements only for gasoline that meets California's gasoline program.[137] As discussed in Section XIII.F.4, we are proposing to expand the applicability of detergents in EPA's gasoline detergent program based on the ability of California's program to satisfy EPA requirements for all gasoline. Data used to comply with the Top Tier program is currently accepted for EPA detergent certification in lieu of data using the EPA ASTM D5500 procedure. Data used to satisfy the requirements of the Top Tier program would continue to be accepted to satisfy EPA deposit control requirements.[138] However, the data from the EPA ASTM D5500 procedure would no longer be accepted for new detergents. Existing detergent certifications based on the EPA ASTM D5500 procedure would continue to remain valid indefinitely. As discussed in Section XIII.F.5, stakeholders could petition EPA to adopt updated deposit control test procedures for new detergents.[139] We seek comment on this proposal or whether we should continue to accept data from the EPA ASTM D5500 procedure for new detergents.[140]

Eliminating the separate EPA ASTM D5500 procedure for new detergent deposit control testing combined with the proposed expanded applicability of California-based detergent certifications, would substantially streamline the detergent program. Additive manufacturers would no longer need to be concerned with the difficulties associated with performing a separate EPA ASTM D5500 procedure.

We acknowledge that similar concerns exist regarding the representativeness of the California detergent program's ASTM D5500 procedure (“California ASTM D5500 procedure”). However, we are proposing to continue to accept valid detergent certification under California's program as demonstration of compliance with our requirements because we believe that the more stringent intake valve standard and more representative test fuel specifications for the California ASTM D5500 procedure sufficiently mitigates concerns about the representativeness of the test vehicle.

We also acknowledge that even the Top Tier test procedures are not new. The ASTM D6201 procedure adopted by the Top Tier program in 2004 and it is accepted that the technology in the 25-year-old engine used in the ASTM D6201 procedure is also no longer representative of the majority of the vehicle population.[141] Hence, the updated deposit control test procedure currently under development by CRC would also likely replace to the ASTM D6201 procedure. Some industry representatives stated that the fading relevance of the ASTM D6201 procedure suggests that EPA should defer taking action on retiring the ASTM D5500 procedure until an updated procedure is developed that would replace both the ASTM D6201 and D5500 procedures. Although, we agree that it is appropriate to consider retiring the ASTM D6201 procedure as soon as a replacement procedure is available, we believe that heightened issues regarding the ASTM D5500 procedure no longer allow EPA to rely on it. Issues regarding the continued viability of the ASTM D5500 procedure are more pronounced than those of the ASTM D6201 procedure both because the technology used in the ASTM D5500 procedure is 9 years older and because it requires vehicle mileage accumulation on a test rack whereas the ASTM D6201 procedure is an engine dynamometer laboratory procedure. A number of parts necessary to maintain the vehicle used in the ASTM D5500 procedure are no longer available, forcing the use of substitute parts.[142] The approximately 100-hour ASTM D6201 procedure conducted under controlled laboratory conditions is inherently less variable than the nearly month-long ASTM D5500 road-based procedure, thereby providing improved confidence in the repeatability of the results. Therefore, we believe that it is appropriate to continue to accept data from the ASTM D6201 procedure in the interim while a replacement test is under development, while also disallowing new detergent deposit control testing using the EPA ASTM D5500 procedure.

During the rule development process, some stakeholders stated that disallowing new detergent deposit control testing using the EPA ASTM D5500 procedure in favor of the Top Tier ASTM D6201 procedure or the California ASTM D5500 procedure would represent an increase in stringency in the detergent program that must be supported by an analysis of costs versus benefits. These parties stated that the concentration of detergent required to satisfy the requirements of the California ASTM D5500 procedure and Top Tier ASTM D6201 procedure is somewhat higher and significantly higher, respectively, than required under the EPA ASTM D5500 procedure.[143] We acknowledge that Top Tier, and perhaps the California procedure, could result in higher detergent treat rates. However, we are not proposing to eliminate the use of additives based on the EPA ASTM D5500 procedure. Additive packages can continue to be used at their existing treat rates indefinitely. It is only the use of new additives that would potentially be impacted, and for which we receive only several applications a year. Even then, as discussed in Section XIII.F.5, we are proposing an administrative process whereby industry could petition EPA to adopt updated deposit control test procedures when they become available, provided that such procedures are as least as protective as the currently accepted procedures. This demonstration could be made compared to any of the currently accepted procedures, including the EPA ASTM D5500 procedure.

Furthermore, we have no data to evaluate that there are any emissions benefits for the current vehicle fleet resulting from satisfying any of the current deposit control test procedures discussed in this section. The more modern nature of the California ASTM D5500 procedure and the Top Tier ASTM D6201 procedure should provide greater confidence that compliance with these procedures is providing an emissions benefit, whereas we lack confidence that compliance with the EPA ASTM D5500 procedure is providing any meaningful emissions benefit.

4. Expanding the Applicability of Detergent Certifications Based on Compliance With the California Deposit Control Regulations

Under the current regulations, a detergent certification based on compliance with the California's deposit control regulations may be used to demonstrate compliance with EPA's deposit control requirements only for gasoline that meets the California's compositional requirements and where the detergent is added in a terminal located in the California. This limitation was based on concerns that detergents certified using test fuels representative of California gasoline might not be capable of controlling deposits in gasoline that does not meet California requirements. When our detergent program was finalized in 1996, the composition of gasoline that complies with California standards differed substantially from gasoline that met our requirements.[144] Through subsequent rulemakings, expansion of E10 nationwide, and other market changes, the composition of gasoline made for use outside of California is much closer to that required by California. Therefore, we believe that detergents certified under California's requirements should be capable of controlling deposits in gasoline that meets EPA's standards. Further support for this assessment is that California requires that a detergent limit the accumulation of intake valve deposits to less than 50 mg per valve whereas our program allows the accumulation of up to 100 mg per valve using the ASTM D5500 procedure. Consequently, we are proposing that a detergent certified under California's program could be used to meet our deposit control requirements in all gasoline.

5. Easing the Adoption of Future Updates to Deposit Control Test Procedures

We are co-proposing two approaches regarding the process of updating deposit control test procedures for the future and how regulated parties would reference the specifications for these procedures. The primary approach would be through an administrative process, and the alternative approach would be through a traditional rulemaking process. Under the primary approach, deposit control test procedures accepted by EPA would be specified in a publicly available document that could be updated as EPA accepts new procedures. The use of this streamlined process would greatly facilitate keeping the requirements consistent with current industry practice. For example, the current need for a notice-and-comment rulemaking to amend test procedures specified in the CFR has caused the detergent program to lag far behind in reflecting current industry practice regarding the test fuels used for the ASTM D6201 procedure. Such noncontroversial changes could be made much more been readily through a streamlined process.

Under this approach, stakeholders could petition EPA to adopt changes to the deposit control test procedures previously accepted by EPA (e.g., when an update to an existing test procedure is incorporated into an existing test method). We would then conduct outreach with stakeholders to assess whether there is sufficiently broad support for the proposed change. If we determine that this is the case and the suggested change met applicable requirements, we would publish on our web page and by direct communications with stakeholders that we have accepted the change. We would periodically update the detergent regulations in the CFR to reflect accepted alternatives.

Under the alternative approach, a notice-and-comment rulemaking would always be required to make changes to the deposit control test procedures and the detergent regulations in the CFR would need to be amended before such changes could take effect. Based on historical experience, this process would make it more difficult to remain current with the changing vehicle and fuel marketplace.

6. Removing Expired and Unused Provisions

The detergent program in part 80 includes provisions to allow a detergent to be certified for use in different gasoline pools using test fuels that have specifications representative of the deposit-forming characteristics of these discrete pools. Under the “national-generic” certification option, a detergent can be certified for use in all gasoline containing any approved oxygenate. Other options allow a detergent to be certified for use only within one of the five Petroleum Administration for Defense Districts (PADDs), in regular or premium gasoline, in oxygenated or nonoxygenated gasoline, in gasoline containing a specific oxygenate other than ethanol, or in a segregated gasoline pool defined by the certification applicant. California has separate detergency requirements for gasoline sold in California. We accept detergent certifications under the California program in lieu of meeting our requirements. All applications for detergent certification to date other than those based on the California program have been under the national-generic option.

We are proposing to remove expired and unused provisions in the detergent program to make the detergent regulations more accessible and understandable and eliminate the ongoing costs of maintaining these provisions. Despite the lack of utility of these provisions, there is a cost to both EPA and industry of maintaining an understanding of them as well as the cost of continuing to print them in the CFR. We are proposing to remove regulatory provisions associated with the interim detergent program that were superseded by the detergent program in 1996.[145] We are also proposing to remove the unused options to certify a detergent for a discrete gasoline pool under the PADD-specific, regular versus premium grade, non-oxygenated gasoline, oxygenate-specific, and fuel-specific certification options.[146] We believe that it is reasonable to conclude that these options do not provide a meaningful flexibility to industry given that they have remained unused since the detergent program's inception in 1996. Under part 1090, the detergent program would allow all detergents to be used in all gasoline containing any approved oxygenate, as is the case today under the national-generic detergent certification option. Detergent certifications under California's program would also remain valid.[147]

7. Streamlining the Detergent Registration Process

Detergent manufacturers are currently required under part 80 to submit detergent certification test data and detergent composition information for evaluation and approval by EPA prior to the detergent being used to comply with our deposit control requirements. To speed up the introduction of new detergents and to reduce the burden of detergent certification, we are proposing that detergent manufacturers could begin marketing a detergent once the manufacturer is satisfied that they have met EPA testing requirements without the need for a prior submission of the data to EPA and approval by EPA. Under this approach, detergent manufacturers would be required to submit data that demonstrates compliance with the deposit control testing requirements upon request by EPA.

Composition information is required for all additives that are registered for use in gasoline under our Fuel and Fuel Additive Program in part 79. We are proposing that the additional composition information that is required for detergents to be evaluated for deposit control efficacy under part 80, including the lowest additive concentration (LAC) established by detergent deposit control testing, would be required to be submitted as part of a detergent's part 79 additive registration rather than requiring a separate submission under part 80. Combining all the detergent composition information that must be submitted to EPA under part 79 would reduce the burden of a separate submission under part 80.

8. Simplifying the Detergent Volumetric Accounting Reconciliation Requirements

Detergent blenders must maintain periodic VAR records to demonstrate that they added a volume of detergent to the gasoline they distribute at least as great as the LAC associated with the certification for the detergent that is used. The current VAR provisions require that detergent blenders compile a separate record for each monthly VAR period in a standard format. Detergent blenders stated that the necessary VAR records are kept in electronic form as standard business practice, but that compiling such information into a standard format as required by EPA for each VAR period represents a significant burden. To reduce the burden, they requested that EPA be more flexible regarding the format of these records. We agree that the goals of the VAR program can be achieved while providing the requested flexibility. Removing the requirement that a VAR report be prepared for each accounting period would also eliminate the burden on industry of requesting and on EPA of issuing a waiver from this requirement during emergency situations to ensure the availability of gasoline. Therefore, we are proposing to require that detergent blenders keep the necessary records to demonstrate compliance with detergent LAC requirements for each blending facility in whatever form that is their common practice. The same one calendar month or lesser accounting period would still apply.

9. Removing the Requirement That the Gasoline Portion of E85 Contain Detergent

The current deposit control regulations require that the gasoline portion of E85 must contain a detergent additive at a concentration at least as great as that used during detergent certification testing (referred to as the lowest additive concentration or LAC).[148] The addition of ethanol to gasoline, with detergent at the LAC, to produce E85 results in a detergent concentration that is lower than the LAC due to the increased dilution from the additional ethanol. We proposed to remove this requirement in the 2016 Renewables Enhancement and Growth Support (REGS) rule.[149]

In the REGS rule, we noted that we are not aware of data on the deposit control needs of flex-fuel vehicles (FFVs) that operate on E85. We also related input from stakeholders that as additive concentration diminishes due to dilution with ethanol in making E85, there is a point where the presence of a detergent ceases to be beneficial and can contribute to deposit formation. We also noted that certain detergents are not completely soluble in high ethanol content blends. Comments on the REGS rule were supportive of removing the requirement that the gasoline portion of E85 contain detergents. During the rule development process for this action, stakeholders indicated that they were also supportive of this change. Therefore, we are proposing to remove the current requirement that the gasoline portion of E85 contain detergents.

This action is allowable under the CAA as CAA section 211(l) only refers to deposit control additives for gasoline. E85 is not gasoline because only fuels composed of at least 50 volume percent clear gasoline are included in the gasoline family under part 79 and E85 contains at least 51 volume percent ethanol.[150]

G. In-Line Blending

We are proposing to continue to allow the use of EPA-approved in-line blending waivers. These in-line blending waiver provisions allow refiners to use a procedure to certify batches using in-line blending equipment instead of the more typical batch certification procedures. Under part 80, we have two different sets of requirements for in-line blending for RFG and CG. However, we are proposing to consolidate these two sets of requirements into a single set of requirements for in-line blending in part 1090. For RFG refiners, the in-line blending requirements would remain largely unchanged except that RFG refiners' in-line blending waivers would not have to cover parameters we are proposing to no longer require for the certification of batches of gasoline (discussed in more detail in Section V.A.2). RFG refiners would still need to arrange for an annual audit to ensure that the terms of the in-line blending waiver are being implemented appropriately. For CG refiners, we are proposing to allow in-line blending waivers to cover all regulated gasoline parameters instead of just sulfur. CG refiners would also have to undergo the same annual audit procedure for RFG refiners that currently exists under part 80. We believe that the flexibility to cover additional parameters for CG refiners through the in-line blending waiver would far exceed any costs associated with the additional audit.

Due to the substantial proposed changes in part 1090 to the existing requirements for in-line blending waivers, we are proposing to require that all refiners with an existing in-line blending waiver would need to resubmit their in-line blending waiver requests. We believe this is necessary to ensure that in-line blending waivers appropriately cover the proposed changes to the in-line blending requirements. Due to the time it would take for refiners to prepare new submissions and for us to review and approve those submissions, we are proposing to allow refiners to operate under their existing part 80 in-line blending waiver until January 1, 2022, a full year after we are proposing to implement most other proposed part 1090 provisions. We believe this would provide an adequate amount of time for refiners to submit and receive new in-line blending waivers. We seek comment on whether we should require resubmissions and whether we are providing an adequate amount of time for refiners to do so.

H. Confidential Business Information

We are proposing regulations that would streamline our processing of claims that requests for exemptions or flexibilities should be withheld from public disclosure under Exemption 4 of the Freedom of Information Act (FOIA), 5 U.S.C. 552(b)(4), as CBI. If finalized, the rules would identify certain types of information collected by EPA under part 1090 that EPA will consider as not entitled to confidential treatment pursuant to Exemption 4 of the FOIA and which EPA will release without further notice.

Exemption 4 of the FOIA exempts from disclosure “trade secrets and commercial or financial information obtained from a person [that is] privileged or confidential.” [151] In order for information to meet the requirements of Exemption 4, EPA must find that the information is either: (1) A trade secret, or (2) commercial or financial information that is: (a) Obtained from a person, and (b) privileged or confidential. Information meeting these criteria is commonly referred to as CBI.[152]

In June 2019, the U.S. Supreme Court issued its decision in Food Marketing Institute v. Argus Leader Media, 139 S. Ct. 2356, 2366 (2019) (Argus Leader). Argus Leader addressed the meaning of “confidential” within the context of FOIA Exemption 4. The Court held that “[a]t least where commercial or financial information is both customarily and actually treated as private by its owner and provided to the government under an assurance of privacy, the information is `confidential' within the meaning of Exemption 4.” [153] The Court identified two conditions “that might be required for information communicated to another to be considered confidential.” [154] Under the first condition, “information communicated to another remains confidential whenever it is customarily kept private, or at least closely held, by the person imparting it.” (internal citations omitted). The second condition provides that “information might be considered confidential only if the party receiving it provides some assurance that it will remain secret.” (internal citations omitted). The Court found the first condition necessary for information to be considered confidential within the meaning of Exemption 4, but did not address whether the second condition must also be met.

Following issuance of the Court's opinion, the U.S. Department of Justice (DOJ) issued guidance concerning the confidentiality prong of Exemption 4, articulating “the newly defined contours of Exemption 4” post-Argus Leader.[155] Where the government provides an express or implied indication to the submitter prior to or at the time the information is submitted to the government that the government would publicly disclose the information, then the submitter cannot reasonably expect confidentiality of the information upon submission, and the information is not entitled to confidential treatment under Exemption 4.[156]

Here, EPA is providing an express indication that we may release certain basic information incorporated into EPA actions on petitions and submissions, as well as information contained in submissions to EPA under part 1090 without further notice, and that such information will not be entitled to confidential treatment under Exemption 4 of the FOIA. In particular, this decision applies to requests under the following processes: Testing and R&D exemptions under 40 CFR 1090.610, hardship exemptions under 40 CFR 1090.635, alternative quality assurance programs under 40 CFR 1090.505, alternative PTD language under 40 CFR 1090.1175, in-line blending waivers under 40 CFR 1090.1315, alternative measurement procedures under 40 CFR 1090.1365, survey plans under 40 CFR 1090.1400, and alternative labels under 40 CFR 1090.1500. Accordingly, such information may be released without further notice to the submitter and without following EPA's procedures set forth in 40 CFR part 2, subpart B. Thus, to expedite processing of information requests and increase transparency related to EPA determinations, we are proposing to clarify in the regulations that a clearly delineated set of basic information related to our decisions on exemptions, waivers, and alternative procedures under part 1090 will not be treated as confidential.

In this action, we are, by rulemaking, providing potential submitters notice of our intent to release particular information related to future submissions. We are proposing that upon receipt of submissions, we may release the following information: Submitter's name; the name and location of the facility for which relief is requested, if applicable; the general nature of the request; and the relevant time period for the request, if applicable. Additionally, once we have adjudicated submissions, we may release the following additional information: The extent to which EPA either granted or denied the request, and any relevant conditions. For information submitted under part 1090 claimed as confidential that is outside the categories described above, and not specified in the proposed regulations at 40 CFR 1090.15(b) or (c), EPA will evaluate such confidentiality claims in accordance with our regulations at 40 CFR part 2, subpart B.

We find that it is appropriate to release the information described above in the interest of transparency and to provide the public with information about entities seeking exemptions or requests for alternative compliance procedures under part 1090. This approach will also provide certainty to submitters regarding the release of information under part 1090. With this advance notice, each potential submitter will have the discretion to decide whether to make such a request with the understanding that EPA may release certain information about the request without further notice.

XIV. Costs and Benefits

A. Overview

In general, we expect that this action would reduce the cost of fuel distribution by improving fuel fungibility, reduce the costs for regulated parties to comply with our fuel quality regulations, and reduce the costs for EPA to implement those regulations. We do not expect a measurable effect on regulated emissions or air quality as this rule is not proposing to change the stringency of our fuel quality standards. This section lays out the general areas of potential cost savings for producing fuels that would result if the proposing streamlining rule was finalized. We outline in more detail these areas for savings in a technical memo to the docket.[157] We specifically solicit comment on quantifying cost savings associated with increased fungibility of fuels, as well as the tables provided and assumptions invoked in the technical memo.

B. Reduced Fuel Costs to Consumers From Improved Fuel Fungibility

A number of the provisions being proposed in part 1090 are expected to improve fuel fungibility. This would result in decreased costs associated with the distribution and sale of such fuels. Some examples of ways that this could result in potential cost savings is from the decreased need for separate tanks at terminals, the shipment of larger batches of fuels through pipelines with less interface downgrade, and fewer constraints on distribution and use of certain fuels in various markets (e.g., winter RFG in CG areas). While we believe that these types of savings could be significant, especially when applied to the national gasoline and diesel fuel pools, these types of costs savings are difficult to quantify. We reached out to stakeholders to attempt to quantify potential costs savings and did not receive any information that would help us determine cost savings from increased fuel fungibility. Therefore, we seek comment on potential cost savings as from increased fuel fungibility directly for the proposed fuels regulatory streamlining provisions.

C. Costs and Benefits for Regulated Parties

We anticipate that the proposed streamlined fuels provisions would significantly reduce the administrative burden for regulated parties to comply with our fuel quality standards. The opportunities to reduce such administrative burden have been discussed throughout this proposal. Some examples of areas where savings could result are the decrease in the number of fuel parameters needed to be tested to certify gasoline (discussed in Section V.A.2), the reduction in the number and frequency of reports submitted to EPA to demonstrate compliance with our gasoline requirements (discussed in Section VIII.C), and cost savings associated with consolidating the current four in-use survey programs into a single, national in-use survey program.

In general, estimates in administrative burden reduction are captured in the supporting statement for the proposed information collection request (ICR) required under the Paperwork Reduction Act (PRA) and discussed in more detail in Section XV.C.[158] As part of this action, we are proposing to replace the multiple existing ICRs for part 80 into a single ICR for all fuel programs that would now be included in part 1090. As part of that process, we are comparing the administrative burden from the existing ICRs to the estimated administrative burden in the proposed ICR. This results in a change of about $4.6 million less per year. Furthermore, we discuss additional areas of potential administrative savings for industry that may not be captured in ICRs in a technical memorandum.[159] We estimate that there are potential savings of about $28.3 million per year. Including the $4.6 million cost reductions estimated under the ICR, the total estimated savings in administrative costs to industry is $32.9 million per year. Table XIV.C-1 outlines the categories identified for savings, which are described in detail in a memorandum to the docket.[160]

Open Table

Table XIV.C-1—Estimated Annual Cost Savings by Savings Category 1

Savings category Savings (in millions)
Eliminate Olefin, Aromatics and Distillation Testing $5.4
Fewer Batch Reports 4.5
Less Retail Sampling 1.5

Independent Labs 0.6
Oversight Testing 0.2
Barge Distribution Savings 13.8
Information Collection Request 4.6
Total Savings 32.9
1 Cost savings in 2019 dollars.

In addition, there are other potential savings for all stakeholders that are more difficult to quantify. For example, an expected consequence of making the regulations clearer and less complex would be less time and effort for staff to understand our regulations and fewer inquiries to EPA or to hired consultants to untangle regulatory ambiguity.

Aspects of this action that are expected to increase costs are expected to be small and offset by a large margin by savings in provisions they replace. Since we are not proposing changes to the stringency of our standards, we do not expect fuel manufacturers to have to alter their production processes in order to comply with the proposed streamlined regulations. In prior fuels rulemakings, retooling petroleum refiners often serve as the most significant costs associated with changes in fuel standards. Similarly, other parties in the fuel distribution system should not be expected to have to make any costly adjustments to how they produce, distribute, and sell fuels, fuel additives, and regulated blendstocks. We do expect there may be some one-time costs associated with updating recordkeeping and reporting requirements associated with the proposed requirements. For example, parties would most likely need to change PTDs to reflect the proposed streamlined language. These costs are expected to be small and are reflected in the ICR supporting statement.[161]

Overall, we expect the savings from increased fungibility of fuels, the decrease in administrative costs, and other indirect cost savings resulting from the proposal to far exceed any one-time administrative costs needed to begin compliance with the proposed streamlined fuel quality regulations. These cost savings would be expected to be passed along to consumers in the form of lower fuel prices, given the highly competitive fuel marketplace. We discuss many of these areas, including a much more detailed analysis of the cost savings, in a technical memorandum [162] and the ICR supporting statement.[163] We also estimated the total new present value cost savings if the total savings are carried out over 30 years at a 3 percent and 7 percent discounted rate, which are presented in Table XIV.C-2.[164]

We seek comment on the potential costs and benefits that would result from this action and whether there are other costs and benefits that we should consider.

D. Environmental Impacts

Since we are not proposing to make changes to the stringency of the existing fuel quality standards, we do not expect any measurable impact on regulated emissions or air quality. However, as discussed in more detail throughout the preamble, there are certain areas of this action where changes to compliance requirements could be viewed as marginally affecting in-use fuel quality. These marginal changes could then have a ripple effect on regulated emissions. In general, such changes would be very small, typically well below the levels that we have historically attempted to quantify in rulemakings where we establish fuel standards. Given the relative size of such changes, it would be difficult if not impossible to make an estimate with any level of confidence on the air quality effects that would result from this action. Despite this limitation, we have attempted to at least identify potential areas that could have an effect on in-use fuel quality.

First, we have heard concerns that the proposed RFG RVP maximum per-gallon of 7.4 psi, which is higher than the estimated RFG average RVP of 7.1-7.2 psi. might be perceived as a decrease in in-use fuel quality. Section V discusses why we believe that based on historical information, the fuel system builds in compliance margins to assure that per-gallon RVP standards are met and result in RVP averages that are between 0.2-0.3 psi lower than the maximum per-gallon standard. We have also maintained limitations on the addition of certified butane and pentane to summer RFG to help ensure that an average RVP of 7.1-7.2 psi is realized in-use for summer RFG. Furthermore, by consolidating the three RFG VOC performance standards to the most stringent standard, there may be a slight reduction in the RVP of RFG supplied to areas with the less stringent VOC performance standards.

Second, we heard that by allowing manufacturers of CG to account for oxygenate added downstream, any current unintentional overcompliance with the gasoline average benzene and sulfur standards would be lost, resulting in a slight increase in the benzene and sulfur contents of the fuel pool. While this could result in a slight increase in the amount of benzene and sulfur in the national fuel pool,[165] we believe there are some other elements that could offset or eclipse these potential increases, making any real world quantification difficult. One is the downstream BOB recertification procedures that would require downstream parties that recertify BOBs for less oxygenate to make up for the unrealized dilution of sulfur and benzene through retiring credits (e.g., if a party recertifies an E10 BOB as an E0 gasoline). This would pull sulfur and benzene out of the gasoline fuel pool and help offset some of the reduction in overcompliance. Additionally, we are not allowing the generation of credits from the over blending of oxygenates into BOB (e.g., if a party recertifies an E10 BOB as E15). This would further dilute the amount of sulfur and benzene in the gasoline pool and help offset any perceived reduction in overcompliance.

During the rule development process, we also heard from stakeholders concerns that reducing the parameters needed to certify gasoline would make it easier for parties to blend dirtier gasoline and not comply with our fuel quality requirements. Other stakeholders suggested that the reduced reporting requirements would make it more difficult for EPA to oversee compliance with the fuel requirements. We believe the improved oversight, especially by third-party surveys, would address these concerns and, contrary to the concerns expressed, may improve the quality of fuel sold at retail. While fuel manufacturers would still be required to certify fuels for conformance with EPA fuel quality standards, the issue is that fuels are now blended with oxygenates, additives, and blendstocks at various points along the distribution chain before the fuels are used in vehicles and engines. Under the existing regulations, EPA monitors the quality of gasoline primarily at the refinery gate, not downstream at retail. The proposed national in-use survey program is designed to ensure that fuels continue to meet our standards when they are dispensed from retail stations and would help provide valuable information for EPA to oversee the fuel quality programs. In addition, the proposed voluntary national oversight program would ensure that manufacturers are sampling and testing in a manner consistent with our regulations to help ensure that parties are not biasing test results to make dirtier fuels. We also believe that by proposing to simplify and modernize our reporting requirements, we will be better able to oversee the fuel quality program as information is more readily available.

Taken together, we believe the proposed streamlining of the fuel quality programs would on balance ensure greater compliance with our regulatory requirements by making the requirements more intuitive to the regulated community to comply with. We also believe the increased oversight mechanisms proposed would allow us to better oversee compliance with the current fuel standards and take appropriate action when issues are identified. The net result of this could be a slight improvement in fuel quality across the national fuel pool; however, such an effect is difficult to quantify.

XV. Statutory and Executive Order Reviews

Additional information about these statutes and Executive Orders can be found at http://www.epa.gov/​laws-regulations/​laws-and-executive-orders.

A. Executive Order 12866: Regulatory Planning and Review and Executive Order 13563: Improving Regulation and Regulatory Review

This action is a significant regulatory action that was submitted to the Office of Management and Budget (OMB) for review. Any changes made in response to OMB recommendations have been documented in the docket. EPA prepared an economic analysis of the potential costs and benefits associated with this action. This analysis, “Economic Analysis: Fuels Regulatory Streamlining Proposed Rule,” is available in the docket.

B. Executive Order 13771: Reducing Regulations and Controlling Regulatory Costs

This action is expected to be an Executive Order 13771 deregulatory action. Details on the estimated cost savings of this proposed rule can be found in our analysis of the potential costs and benefits associated with this action in Section XIV.

C. Paperwork Reduction Act (PRA)

The information collection activities in this proposed rule have been submitted for approval to the Office of Management and Budget (OMB) under the PRA. The Information Collection Request (ICR) document that EPA prepared has been assigned OMB ICR number 2060-NEW; EPA ICR number 2607.01. You can find a copy of the ICR in the docket for this rule, and it is briefly summarized here.

The information collection activities under this proposed rule are similar to those under existing 40 CFR part 80 and include familiar requirements for respondents to register, report, sample, and test gasoline for four parameters (i.e., sulfur, benzene, seasonal RVP and oxygenate/oxygen content in the cases of gasoline and sulfur in the case of diesel), keep records in the normal course of business (e.g., PTDs and test results, as applicable), participate in surveys, conduct attest engagements, and apply pump labels. Many parties are already registered under part 80 and would not have to re-register under the proposed approach. The exact information collection requirements proposed are tied to the party's control over the quality and type of fuel—for example, a refiner of gasoline has great control over the quality and type of fuel and has proposed registration, reporting, sampling, testing, recordkeeping, survey, and attest engagement responsibilities; a party who owns a retail station has only limited, proposed information collection requirements involving the retention of customary business records (e.g., PTDs) and affixing labels to certain pumps from which fuel is dispensed. The proposed information collection for part 1090 would not result in duplication of requirements under existing part 80, as this proposed regulation would replace nearly all non-RFS provisions under the existing part.

Respondents/affected entities: The respondents to this information collection are parties involved in the manufacture, blending, distribution, sale, or dispensing of regulated fuels and fuel blendstocks. These include refiners, importers, blenders, terminals and pipelines, truck facilities, fuel retailers, and wholesale purchaser-consumers.

Respondent's obligation to respond: Mandatory, under proposed 40 CFR part 1090.

Estimated number of respondents: 182,269.

Frequency of response: Annual and occasionally.

Total estimated burden: 522,368 hours (per year). Burden is defined at 5 CFR 1320.3(b).

Total estimated cost: $ 56,744,171 (per year) including, $5,744,016 annualized capital or operation and maintenance costs.

An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number. The OMB control numbers for EPA's regulations in 40 CFR are listed in 40 CFR part 9.

Submit your comments on EPA's need for this information, the accuracy of the provided burden estimates and any suggested methods for minimizing respondent burden to EPA using the docket identified at the beginning of this rule. You may also send your ICR-related comments to OMB's Office of Information and Regulatory Affairs. These comments and recommendations for the proposed information collection should be sent within 30 days of publication of this notice to www.reginfo.gov/​public/​do/​PRAMain. Find this particular information collection by selecting “Currently under 30-day Review—Open for Public Comments” or by using the search function. EPA will respond to any ICR-related comments in the final rule.

D. Regulatory Flexibility Act (RFA)

I certify that this action will not have a significant economic impact on a substantial number of small entities under the RFA. In making this determination, the impact of concern is any significant adverse economic impact on small entities. An agency may certify that a rule will not have a significant economic impact on a substantial number of small entities if the rule relieves regulatory burden, has no net burden, or otherwise has a positive economic effect on the small entities subject to the rule. This action proposes to consolidate EPA's existing fuel quality regulations into the new 40 CFR part 1090, and the proposed requirements on small entities are largely the same as those already included in the existing 40 CFR part 80 fuel quality regulations. While this action makes relatively minor corrections and modifications to those regulations, we do not anticipate that there will be any significant cost increases associated with these proposed changes—to the contrary, we anticipate cost decreases. We have therefore concluded that this action will have no net regulatory burden for all directly regulated small entities.

E. Unfunded Mandates Reform Act (UMRA)

This action does not contain an unfunded mandate of $100 million or more as described in UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect small governments. This action imposes no enforceable duty on any state, local or tribal governments. Requirements for the private sector do not exceed $100 million in any one year.

F. Executive Order 13132: Federalism

This action does not have federalism implications. It will not have substantial direct effects on the states, on the relationship between the national government and the states, or on the distribution of power and responsibilities among the various levels of government. However, to the extent that states have adopted fuel regulations based on EPA's regulatory provisions that we are proposing to change, states may need to make corresponding changes to their regulations to maintain their effectiveness.

Although Executive Order 13132 does not apply to this proposed rule, EPA did consult with representatives of various State and local governments in developing this rule. EPA has also consulted with representatives from the National Association of Clean Air Agencies (NACAA, representing state and local air pollution officials), Association of Air Pollution Control Agencies (AAPCA, representing state and local air pollution officials), and Northeast States for Coordinated Air Use Management (NESCAUM, the Clean Air Association of the Northeast States). In the spirit of Executive Order 13132, and consistent with EPA policy to promote communications between EPA and state and local governments, EPA specifically solicits comment on this proposed action from state and local officials.

G. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments

This action does not have tribal implications as specified in Executive Order 13175. This proposed rule will be implemented at the Federal level and potentially affects transportation fuel refiners, blenders, marketers, distributors, importers, exporters, and renewable fuel producers and importers. Tribal governments would be affected only to the extent they produce, purchase, and use regulated fuels. Thus, Executive Order 13175 does not apply to this action.

H. Executive Order 13045: Protection of Children From Environmental Health Risks and Safety Risks

EPA interprets Executive Order 13045 as applying only to those regulatory actions that concern environmental health or safety risks that EPA has reason to believe may disproportionately affect children, per the definition of “covered regulatory action” in section 2-202 of the Executive Order. This action is not subject to Executive Order 13045 because it does not concern an environmental health risk or safety risk.

I. Executive Order 13211: Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use

This action is not a “significant energy action” because it is not likely to have a significant adverse effect on the supply, distribution, or use of energy. This action proposes to consolidate EPA's existing fuel quality regulations into a new part, consistent with the CAA and authorities provided therein. There are no additional costs for sources in the energy supply, distribution, or use sectors. The proposed action would only be anticipated to improve fuel fungibility and therefore enhance fuel supply and distribution but in ways that are not readily quantifiable.

J. National Technology Transfer and Advancement Act (NTTAA) and 1 CFR Part 51

This proposed action involves technical standards. We are proposing to update a number of regulations that already contain voluntary consensus standards (VCS), practices, and specifications to more recent versions of these standards. In accordance with the requirements of 1 CFR 51.5, we are proposing to incorporate by reference the use of test methods and standards from American Institute of Certified Public Accountants, American Society for Testing and Materials International (ASTM International), National Institute of Standards and Technology (NIST), and The Institute of Internal Auditors. A detailed discussion of these test methods and standards can be found in Sections III.D.3, VII.F, VIII.F, IX, and XIII.F. The standards and test methods may be obtained through the American Institute of Certified Public Accountants website (www.aicpa.org) or by calling (888) 777-7077, ASTM International website (www.astm.org) or by calling ASTM at (610) 832-9585, the National Institute of Standards and Technology website (www.nist.gov) or by calling NIST at (301) 975-6478, and The Institute of Internal Auditors website (www.theiia.org) or by calling (407) 937-1111.

This rulemaking involves environmental monitoring or measurement. Consistent with EPA's Performance Based Measurement System (PBMS), for those fuel parameters that fall under PBMS, such as sulfur, benzene, Reid Vapor Pressure, and oxygenate content, we are proposing not to require the use of specific, prescribed analytic methods. Rather, we are proposing to allow the use of any method that meets the prescribed performance criteria. The PBMS approach is intended to be more flexible and cost-effective for the regulated community; it is also intended to encourage innovation in analytical technology and improved data quality. We are not precluding the use of any method, whether or not it constitutes a voluntary consensus standard, so long as it meets the performance criteria specified. We are also proposing the use of specific standard practices or test methods for situations when PBMS would not be applicable, such as gasoline detergency certification test methods or references to gasoline specification ASTM D4814 or ethanol specification ASTM D4806.

ASTM International routinely updates many of its reference documents. If ASTM International publishes an updated version of any of reference documents included in this proposal, we will consider referencing that updated version in the final rule.

K. Executive Order 12898: Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Populations

EPA believes that this action does not have disproportionately high and adverse human health or environmental effects on minority populations, low income populations, and/or indigenous peoples, as specified in Executive Order 12898 (59 FR 7629, February 16, 1994). This proposed rule does not affect the level of protection provided to human health or the environment by applicable air quality standards. This action does not relax the control measures on sources regulated by EPA's fuel quality regulations and therefore will not cause emissions increases from these sources.

XVI. Statutory Authority

Statutory authority for this action comes from sections 202, 203-209, 211, 213, 216, and 301 of the Clean Air Act, 42 U.S.C. 7414, 7521, 7522-7525, 7541, 7542, 7543, 7545, 7547, 7550, and 7601. Additional support for the procedural and compliance related aspects of this proposed rule comes from sections 114, 208, and 301(a) of the Clean Air Act, 42 U.S.C. 7414, 7521, 7542, and 7601(a).

Andrew Wheeler,

Administrator.

For the reasons set forth in the preamble, EPA proposes to amend 40 CFR parts 79, 80, 86, 1037, and 1090 as follows:

PART 79—REGISTRATION OF FUEL AND FUEL ADDITIVES

1. The authority citation for part 79 continues to read as follows:

Authority: 42 U.S.C. 7414, 7524, 7545, and 7601.

Subpart A—General Provisions

2. Amend § 79.5 by revising paragraph (a)(1) to read as follows:

Periodic reporting requirements.

(a) * * * (1) For each calendar year (January 1 through December 31) commencing after the date prescribed for any fuel in subpart D of this part, fuel manufacturers must submit to the Administrator a report for each registered fuel showing the range of concentration of each additive reported under § 79.11(a) and the volume of such fuel produced in the year. Reports must be submitted by March 31 for the preceding year, or part thereof, on forms supplied by the Administrator. If the date prescribed for a particular additive in subpart D of this part, or the later registration of an additive is between October 1 and December 31, no report will be required for the period to the end of that year.

* * * * *

Subpart C—Additive Registration Procedures

3. Amend § 79.21 by:

a. Revising paragraphs (f) and (g); and

b. Adding paragraph (j).

The revisions and addition read as follows:

Information and assurances to be provided by the additive manufacturer.
* * * * *

(f) Assurances that any change in information submitted pursuant to:

(1) Paragraphs (a), (b), (c), (d), and (j) of this section will be provided to the Administrator in writing within 30 days of such change; and

(2) Paragraph (e) of this section as provided in § 79.5(b).

(g)(1) Assurances that the additive manufacturer will not represent, directly or indirectly, in any notice, circular, letter, or other written communication or any written, oral, or pictorial notice or other announcement in any publication or by radio or television, that registration of the additive constitutes endorsement, certification, or approval by any agency of the United States, except as specified in paragraph (g)(2) of this section.

(2) In the case of an additive that has its purpose-in-use identified as a deposit control additive for use in gasoline pursuant to the requirements of paragraph (d) of this section, the additive manufacturer may publicly represent that the additive meets the EPA's gasoline deposit control requirements, provided that the additive manufacturer is in compliance with the requirements of 40 CFR 1090.240.

* * * * *

(j) If the purpose-in-use of the additive identified pursuant to the requirements of paragraph (d) of this section is a deposit control additive for use in gasoline, the manufacturer must submit the following in addition to the other information specified in this section:

(1) The lowest additive concentration (LAC) that is compliant with the gasoline deposit control requirements of 40 CFR 1090.240.

(2) The deposit control test method in 40 CFR 1090.1395 that the additive is compliant with.

(3) A complete listing of the additive's components and the weight or volume percent (as applicable) of each component.

(i) When possible, standard chemical nomenclature must be used or the chemical structure of the component must be given. Polymeric components may be reported as the product of other chemical reactants, provided that the supporting data specified in paragraph (j)(3) of this section is also reported.

(ii) Each detergent-active component of the package must be classified into one of the following designations:

(A) Polyalkyl amine.

(B) Polyether amine.

(C) Polyalkylsuccinimide.

(D) Polyalkylaminophenol.

(E) Detergent-active petroleum-based carrier oil.

(F) Detergent-active synthetic carrier oil.

(G) Other detergent-active component (identify category, if feasible).

(iii) Composition variability. (A) The composition of a detergent additive reported in a single additive registration (and the detergent additive product sold under a single additive registration) may not include the following:

(1) Detergent-active components that differ in identity from those contained in the detergent additive package at the time of deposit control testing.

(2) A range of concentrations for any detergent-active component such that, if the component were present in the detergent additive package at the lower bound of the reported range, the deposit control effectiveness of the additive package would be reduced as compared with the level of effectiveness demonstrated pursuant to the requirements of 40 CFR 1090.240. Subject to the foregoing constraint, a gasoline detergent additive sold under a particular additive registration may contain a higher concentration of the detergent-active component(s) than the concentration(s) of such component(s) reported in the registration for the additive.

(B) The identity or concentration of non-detergent-active components of the detergent additive package may vary under a single registration provided that such variability does not reduce the deposit control effectiveness of the additive package as compared with the level of effectiveness demonstrated pursuant to the requirements of 40 CFR 1090.240.

(C) Unless the additive manufacturer provides EPA with data to substantiate that a carrier oil does not act to enhance the detergent additive's ability to control deposits, any carrier oil contained in the detergent additive, whether petroleum-based or synthetic, must be treated as a detergent-active component in accordance with the requirements in paragraph (j)(3)(ii) of this section.

(D) Except as provided in paragraph (j)(3)(iii)(E) of this section, detergent additive packages that do not satisfy the requirements in paragraphs (j)(3)(iii)(A) through (C) must be separately registered. EPA may disqualify an additive for use in satisfying the requirements of this subpart if EPA determines that the variability included within a given detergent additive registration may reduce the deposit control effectiveness of the detergent package such that it may invalidate the lowest additive concentration reported in accordance with the requirements of paragraph (j)(1) of this section and 40 CFR 1090.240.

(E) A change in minimum concentration requirements resulting from a modification of detergent additive composition does not require a new detergent additive registration or a change in existing registration if the modification is affected by a detergent blender pursuant to the requirements of 40 CFR 1090.1240.

(4) For detergent-active polymers and detergent-active carrier oils that are reported as the product of other chemical reactants:

(i) Identification of the reactant materials and the manufacturer's acceptance criteria for determining that these materials are suitable for use in synthesizing detergent components. The manufacturer must maintain documentation, and submit it to EPA upon request, demonstrating that the acceptance criteria reported to EPA are the same criteria which the manufacturer specifies to the suppliers of the reactant materials.

(ii) A Gel Permeation Chromatograph (GPC), providing the molecular weight distribution of the polymer or detergent-active carrier oil components and the concentration of each chromatographic peak representing more than one percent of the total mass. For these results to be acceptable, the GPC test procedure must include equipment calibration with a polystyrene standard or other readily attainable and generally accepted calibration standard. The identity of the calibration standard must be provided, together with the GPC characterization of the standard.

(5) For non-detergent-active carrier oils, the following parameters:

(i) T10, T50, and T90 distillation points, and end boiling point, measured according to applicable test procedures cited in 40 CFR 1090.1350.

(ii) API gravity and viscosity.

(iii) Concentration of oxygen, sulfur, and nitrogen, if greater than or equal to 0.5 percent (by weight) of the carrier oil.

(6) Description of an FTIR-based method appropriate for identifying the detergent additive package and its detergent-active components (polymers, carrier oils, and others) both qualitatively and quantitatively, together with the actual infrared spectra of the detergent additive package and each detergent-active component obtained by this test method. The FTIR infrared spectra submitted in connection with the registration of a detergent additive package must reflect the results of a test conducted on a sample of the additive containing the detergent-active component(s) at a concentration no lower than the concentration(s) (or the lower bound of a range of concentration) reported in the registration pursuant to paragraph (j)(1) of this section.

(7) Specific physical parameters must be identified which the manufacturer considers adequate and appropriate, in combination with other information in this section, for identifying the detergent additive package and monitoring its production quality control.

(i) Such parameters must include (but need not be limited to) viscosity, density, and basic nitrogen content, unless the additive manufacturer specifically requests, and EPA approves, the substitution of other parameter(s) which the manufacturer considers to be more appropriate for a particular additive package. The request must be made in writing and must include an explanation of how the requested physical parameter(s) are helpful as indicator(s) of detergent production quality control. EPA will respond to such requests in writing; the additional parameters are not approved until the manufacturer receives EPA's written approval.

(ii) The manufacturer must identify a standardized measurement method, consistent with the chemical and physical nature of the detergent product, which will be used to measure each parameter. The documented ASTM repeatability for the method must also be cited. The manufacturer's target value for each parameter in the additive, and the expected range of production values for each parameter, must be specified.

(iii) The expected range of variability must differ from the target value by an amount no greater than five times the standard repeatability of the test procedure, or by no more than 10 percent of the target value, whichever is less. However, in the case of nitrogen analysis or other procedures for measuring concentrations of specific chemical compounds or elements, when the target value is less than 10 parts per million, a range of variability up to 50 percent of the target value will be considered acceptable.

(iv) If a manufacturer wishes to rely on measurement methods or production variability ranges which do not conform to the above limitations, then the manufacturer must receive prior written approval from EPA. A request for such allowance must be made in writing. It must fully justify the adequacy of the test procedure, explain why a broader range of variability is required, and provide evidence that the production detergent will perform adequately throughout the requested range of variability pursuant to the requirements of 40 CFR 1090.1395.

4. Revise § 79.24 to read as follows:

Termination of registration of additives.

(a) Registration may be terminated by the Administrator if the additive manufacturer requests such termination in writing.

(b) Registration for an additive for an additive that has its purpose-in-use identified as a deposit control additive for use in gasoline pursuant to the requirements of § 79.21(d) may be terminated by the Administrator if the EPA determines that the detergent additive is not compliant with the gasoline deposit control requirements of 40 CFR 1090.240.

Subpart C—Additive Registration Procedures

5. Amend § 79.32 by revising paragraph (c) to read as follows:

Motor vehicle gasoline.
* * * * *

(c) Fuel manufacturers must submit the reports specified in 40 CFR part 1090, subpart J.

* * * * *

6. Amend § 79.33 by revising paragraph (c) to read as follows:

3 Motor vehicle diesel.
* * * * *

(c) Fuel manufacturers must submit the reports specified in 40 CFR part 1090, subpart J.

* * * * *

Subpart A—General Provisions

8. Revise § 80.1 to read as follows:

Scope.

(a) This part prescribes regulations for the renewable fuel program under the Clean Air Act section 211(o) (42 U.S.C. 7545(o)).

(b) This part also prescribes regulations for the labeling of fuel dispensing systems for oxygenated gasoline at retail under the Clean Air Act section 211(m)(4) (42 U.S.C. 7545(m)(4)).

(c) Nothing in this part is intended to preempt the ability of state or local governments to control or prohibit any fuel or fuel additive for use in motor vehicles and motor vehicle engines which is not explicitly regulated by this part.

9. Revise § 80.2 to read as follows:

Definitions.

Definitions apply in this part as described in this section.

Explanatory terms.

This section explains how certain phrases and terms are used in this part, especially those used to clarify and explain regulatory provisions. They do not, however, constitute specific regulatory requirements and as such do not impose any compliance obligation on regulated persons.

(a) Types of provisions. The term “provision” includes all aspects of the regulations in this part. As described in this section, regulatory provisions include standards, requirements, and prohibitions, along with a variety of other types of provisions. In certain cases, these terms apply to some but not all the provisions of a part or section. For example, recordkeeping requirements apply to jet fuel even though it is not subject to standards under this part.

(1) A standard is a limit on the formulation, components, or characteristics of any fuel, fuel additive, or regulated blendstock, established by regulation under this part. Compliance with or conformance to a standard is a specific type of requirement, and in some cases a standard may be discussed as a requirement. Thus, a statement about the requirements of a part or section also applies with respect to the standards in the part or section. Examples of standards include the sulfur per-gallon standards for gasoline and diesel fuel.

(2) While requirements state what someone must do, prohibitions state what someone may not do. Prohibitions are often referred to as prohibited acts. Failing to meet any requirement that applies to a person under this part is a prohibited act.

(3) The regulations in this part include provisions that are not standards, requirements, or prohibitions, such as definitions.

(b) A fuel is considered “subject to” a specific provision if that provision applies, even if it falls within an exemption authorized under a different part of this regulation. For example, gasoline is subject to the provisions of this part even if it is exempted from the standards under subpart G of this part.

(c) Singular and plural. Unless stated otherwise or unless it is clear from the regulatory context, provisions written in singular form include the plural form and provisions written in plural form include the singular form.

(d) Inclusive lists. Lists in the regulations in this part prefaced by “including” or “this includes” are not exhaustive. The terms “including” and “this includes” should be read to mean “including but not limited to” and “this includes but is not limited to.”

(e) Notes. Statements that begin with “Note:” or “Note that” are intended to clarify specific regulatory provisions stated elsewhere in the regulations in this part. By themselves, such statements are not intended to specify regulatory requirements.

(f) Examples. Examples provided in the regulations in this part are typically introduced by either “for example” or “such as.” Specific examples given in the regulations do not necessarily represent the most common examples. The regulations may specify examples conditionally (that is, specifying that they are applicable only if certain criteria or conditions are met). Lists of examples cannot be presumed to be exhaustive lists.

(c) Limitations. (1) Only the gasoline manufacturer that first certifies the BOB may account for the downstream addition of oxygenate under this section. On any occasion where any person downstream of the fuel manufacturing facility gate of the gasoline manufacturer that produced or imported gasoline or BOB adds oxygenate to such product, the person may not include the volume and sulfur and benzene content of the oxygenate in any compliance calculations for demonstrating compliance with the average standards specified in subpart C of this part or for credit generation under this subpart. All applicable per-gallon standards specified in subpart C of this part continue to apply.

(2) A person downstream of the fuel manufacturing facility gate may redesignate BOB for use as gasoline without the addition of the specified type and amount of oxygenate if the provisions of § 1090.740 are met.

Subpart M—Sampling, Testing, and Retention

§ 1090.1300
General provisions.

(a) This subpart is organized as follows:

(1) Sections 1090.1310 through 1090.1330 specify the scope of required testing, including special provisions that apply in several unique circumstances.

(2) Sections 1090.1335 through 1090.1345 specify handling procedures for collecting and retaining samples. Sections 1090.1350 through 1090.1375 specify the procedures for measuring the specified parameters. These procedures apply to anyone who performs testing under this subpart.

(3) Section 1090.1390 specifies the requirements for calibrating automated detergent blending equipment.

(4) Section 1090.1395 specifies the procedures for testing related to gasoline deposit control test procedure.

(b) If you need to meet requirements for a quality assurance program at some minimum frequency, your first batch of product triggers the testing requirement. The specified frequency serves as a deadline for performing the required testing, and as a starting point for the next testing period. The following examples illustrate the requirements for testing based on sampling the more frequent of every 90 days or 500,000 gallons of certified butane you received from a supplier:

(1) If your testing period starts on March 1 and you use less than 500,000 gallons of butane from March 1 through May 29 (90 days), you must perform testing under a quality assurance program sometime between March 1 and May 29. Your next test period starts with the use of butane on May 30 and again ends after 90 days or after you use 500,000 gallons of butane, whichever occurs first.

(2) If your testing period starts on March 1 and you use 500,000 gallons of butane for the testing period on April 29 (60 days), you must perform testing under a quality assurance program sometime between March 1 and April 29. Your next testing period starts with the use of butane on April 30 and again ends after 90 days or after you use 500,000 gallons of butane, whichever occurs first.

(c) Anyone performing tests on behalf of a manufacturer to demonstrate compliance with standards or other requirements under this part must meet the requirements of this subpart in the same way that the manufacturer needs to meet requirements for its own testing.

(d) Anyone performing tests under this subpart must apply good laboratory practices for all sampling, measurement, and calculations related to testing required under this part. This requires performing these procedures in a way that is consistent with generally accepted scientific and engineering principles and properly accounting for all available relevant information.

(e) Subpart P of this part has provisions related to importation, including provisions that describe how to meet the sampling and testing requirements of this subpart.

(f) The following general provisions apply:

(1) A crosscheck program is an arrangement for laboratories to perform measurements from test samples prepared from a single homogeneous fuel batch to establish an accepted reference value for evaluating precision and accuracy. This subpart relies on inter-laboratory crosscheck programs sponsored by ASTM International or another voluntary consensus standards body, or on crosscheck programs conducted separately by one or more companies.

(2) A voluntary consensus standards body (VCSB) is an organization that follows consistent protocols to adopt standards reflecting a wide range of input from interested parties. ASTM International and the International Organization for Standardization are examples of VCSB organizations.

§ 1090.1315
In-line blending.

Fuel manufacturers using in-line blending equipment may qualify for a waiver from the requirement in § 1090.1310(b) to test every batch of fuel before the fuel leaves the fuel manufacturing facility as follows:

(a) The waiver in this section applies if you use or intend to use in-line blending equipment to supply fuel directly into a pipeline, marine vessel, or other type of distribution that does not involve collecting fuel in a tank or other type of storage for creating a batch of fuel. It also applies for fuel manufacturers that produce batches of fuel that are too large to contain in available storage tanks.

(b) Waivers granted under 40 CFR part 80 are no longer valid. Any party who received an in-line blending waiver granted under 40 CFR part 80 may continue to operate under the waiver until January 1, 2022. To obtain a waiver under this part, submit a request signed by the RCO to EPA with the following information:

(1) Describe the location of your in-line blending operation, how long it has been in operation, and how much of each type and grade of fuel you have blended over the preceding 3 years (or since starting the in-line blending operation if that is less than 3 years). Describe the physical layout of the blending operation and how you move the blended fuel into distribution. Also describe how your automated system monitors and controls blending proportions and the properties of the blended fuel. For new installations, describe these as a planned operation with projected volumes by type and grade.

(2) Describe how you collect and test composite fuel samples in a way that is equivalent to measuring the fuel properties of a batch of blended fuel as specified in this subpart. Your procedures need to conform to the sampling specifications in ASTM D4177 and the composite calculations in ASTM D5854 (both incorporated by reference in § 1090.95).

(3) Describe any expectation or plan for you or another party to perform additional downstream testing for the same fuel parameters.

(4) Describe your quality assurance procedures. Describe any experiences from the previous 3 years where these quality assurance procedures led you to make corrections to your in-line blending operation.

(5) Describe any times from the previous 3 years that you modified fuel after it came out of your blending operation. Describe how you modified the fuel and why that was necessary.

(6) Describe how you will meet the auditing requirements of paragraph (c) of this section.

(c) You must arrange for an audit of your blending operation each calendar year that reviews procedures and documents to determine whether measured and calculated values properly represent the aggregate fuel properties for the blended fuel.

(d) You must update your in-line blending waiver request 60 days prior to making any material change to your in-line blending process.

(e) If EPA approves your request for a waiver under this section, you may need to update your procedures for more effective control and documentation of measured fuel parameters based on audit results, development of improved practices, or other information.

§ 1090.1320
Adding blendstock to PCG.

The requirements of this section apply for refiners and blending manufacturers that add blendstock to PCG to produce a new batch of gasoline. Paragraph (c) of this section specifies an alternative approach for certified butane and certified pentane blenders. Section 1090.1325 describes additional provisions that apply to transmix processors.

(a) Sample and test using one of the following methods to exclude PCG from the compliance demonstration for sulfur and benzene:

(1) Compliance by subtraction. (i) Sample and test the sulfur and benzene content of each batch of PCG before blending blendstocks to produce a new batch of gasoline.

(ii) Determine the volume of PCG that was blended with blendstock to produce a new batch of gasoline. Report the PCG as a negative batch as specified in § 1090.905(c)(3)(i).

(iii) After adding blendstock to PCG, sample and test the sulfur and benzene content of the new batch of gasoline.

(iv) Determine the volume of the new batch of gasoline. Report the new batch of gasoline as a positive batch as specified in § 1090.905(c)(3)(ii).

(v) Include the PCG batch and the new batch of gasoline in compliance calculations as specified in § 1090.700(d)(4)(i).

(vi) The sample retention requirements in § 1090.1345 apply for both the new batch of gasoline and the associated PCG.

(2) Compliance by addition. (i) Sample and test the sulfur and benzene content of each batch of blendstock used to produce a new batch of gasoline from PCG.

(ii) Determine the volume of each batch of blendstock used to produce the new batch of gasoline.

(iii) Report each batch of blendstock as specified in § 1090.905(c)(4).

(iv) Include each batch of blendstock in compliance calculations as specified in § 1090.700(d)(4)(ii).

(v) The sample retention requirements in § 1090.1345 apply for the new batch of gasoline and for each blendstock.

(b) Regardless of the approach used under paragraph (a) of this section, fuel manufacturers must determine the volume of each blended batch of gasoline, and perform the following measurements for each blended batch of gasoline using the procedures specified in § 1090.1350:

(1) Measure the sulfur content, benzene content, oxygenate content, and for summer gasoline, RVP.

(2) Determine the following distillation parameters: T10, T50, T90, final boiling point, and distillation residue.

(c) Certified butane or certified pentane blenders that blend certified butane or certified pentane into PCG to make a new batch of gasoline may comply with the following requirements instead of the requirements of paragraphs (a) and (b) of this section:

(1) For summer gasoline, measure RVP of the blended fuel. The fuel manufacturer may rely on sulfur and benzene test results from the certified butane or certified pentane producer. Note that § 1090.245(e) disallows adding certified butane and certified pentane to RFG.

(2) Before blending the certified butane or certified pentane with PCG, obtain a copy of the producer's test results indicating that the certified butane or certified pentane meets the standards in § 1090.220 or § 1090.225, respectively.

(3) The certified pentane blender must enter into a contract with the certified pentane producer to verify that the certified pentane producer has an adequate quality assurance program to ensure that the certified pentane received will not be contaminated in transit.

(4) The certified butane or certified pentane blender must conduct a quality assurance program to demonstrate that the certified butane or certified pentane meets the standards specified in § 1090.220 or § 1090.225, respectively. The quality assurance program must be based on sampling the more frequent of every 90 days or 500,000 gallons of certified butane or certified pentane received from each producer. The certified butane or certified pentane blender may rely on a third party to perform the testing.

§ 1090.1325
Adding blendstock to TGP.

The following provisions apply to transmix processors producing gasoline by adding blendstock to TGP:

(a) Perform testing for each batch of summer gasoline to demonstrate compliance with the applicable RVP standard in § 1090.215.

(b) Measure the distillation endpoint for gasoline produced from TGP as specified in § 1090.1350.

(c) Determine the volume, sulfur content, and benzene content of each blendstock batch used to produce gasoline for reporting and compliance calculations by following the sampling and testing requirements in § 1090.1320 and treating the TGP used to produce the gasoline as PCG.

(d) Sample and test the gasoline made from TGP and blendstock to demonstrate compliance with the sulfur per-gallon standard in § 1090.205(b) and the applicable RVP standard in § 1090.215.

(e) Transmix processors producing gasoline by only adding TGP to PCG do not have to measure the benzene content of the finished gasoline. Such transmix processors also do not have to measure the oxygenate content of the finished gasoline if the records for each blendstock show no oxygenate content.

§ 1090.1330
Preparing denatured fuel ethanol.

Instead of measuring every batch, DFE producers and importers may calculate the sulfur content of a batch of DFE as follows:

(a) Determine the sulfur content of ethanol before adding denaturant by measuring it as specified in § 1090.1310 or by estimating it based on your production quality control procedures.

(b) Use the ppm sulfur content of certified ethanol denaturant specified on the PTD for the batch. If the sulfur content is specified as a range, use the maximum specified value.

(c) Calculate the weighted sulfur content of the DFE using the values determined under paragraphs (a) and (b) of this section.

Handling and Preparing Samples

§ 1090.1335
Collecting and preparing samples for testing.

(a) General provisions. Use good laboratory practice to collect samples to represent the batch you are testing. For example, take steps to ensure that a batch is always well mixed before sampling. Also, always take steps to prevent sample contamination, such as completely flushing sampling taps and piping and pre-rinsing sample containers with the product being sampled. Follow the procedures in paragraph (b) of this section for manual sampling. Follow the procedures paragraph (c) of this section for automatic sampling. Additional requirements for measuring RVP are specified in paragraph (d) of this section.

(b) Manual sampling. Perform manual sampling using one of the methods specified in ASTM D4057 (incorporated by reference in § 1090.95) as follows:

(1) Use tap sampling or spot sampling to collect upper, middle, and lower samples. Adjust spot sampling for partially filled tanks as shown in Table 1 or Table 5 of ASTM D4057 as applicable. For tap sampling, collect samples that most closely match the recommendations in Table 5 of ASTM D4057. If you test more than one sample for a given fuel parameter, calculate the arithmetic average of the test results to represent the batch and use the average result for determining compliance with the standards under this part. Each measured sample must meet all applicable per-gallon standards. If you test only one sample for a given parameter, you must use that test result to represent the batch. You may not use the results from a composite sample to determine compliance with the standards under this part.

(2) Collect a “running” or “all-levels” sample from the top of the tank. Drawing a sample from a standpipe is acceptable only if it is slotted or perforated to ensure that the drawn sample properly represents the whole batch of fuel.

(3) If the procedures in paragraphs (b)(1) and (2) of this section are impractical for a given storage configuration, you may use alternative sampling procedures as specified in ASTM D4057. This applies primarily for sampling with trucks, railcars, retail stations, and other downstream locations.

(4) Test results with manual sampling are valid only after you demonstrate homogeneity as specified in § 1090.1337, except that the homogeneity testing requirement does not apply in the following cases:

(i) There is only a single sample using the procedures specified in paragraph (b)(1) of this section.

(ii) Upright cylindrical tanks that have a liquid depth (from the tank outlet) less than 10 feet.

(iii) You draw spot or tap samples as specified in paragraph (b)(1) of this section and test each sample for every parameter subject to a testing requirement and use the worst-case test result for each parameter for purposes of reporting, meeting per-gallon and average standards, and all other aspects of compliance.

(iv) Sampling at a downstream location where it is not possible to collect separate samples and you take steps to ensure that the batch is well mixed.

(c) Automatic sampling. Perform automatic sampling as specified in ASTM D4177 (incorporated by reference in § 1090.95). Configure the system to ensure a well-mixed stream at the sampling point. The default sampling frequency should follow the recommended approach of at least 9,604 samples to represent a batch. EPA may approve a less frequent sampling strategy under § 1090.1315(b)(2) if it is appropriate for a given facility or for a small-volume batch. Take steps to align the start and end of sampling with the start and end of creating the batch.

(d) Sampling provisions related to measuring RVP of summer gasoline. The following additional provisions apply for preparing samples to measure RVP of summer gasoline:

(1) Meet the additional specifications for manual and automatic sampling in ASTM D5842 (incorporated by reference in § 1090.95).

(2) If you measure RVP for multiple test samples to demonstrate compliance, do not calculate an average result. Rather, each tested sample must meet the applicable RVP standard.

(3) If you measure other fuel parameters for a given sample in addition to RVP testing, always measure RVP first.

§ 1090.1337
Demonstrating homogeneity.

(a) Use the procedures in this section as specified in § 1090.1335 to determine whether a batch is homogeneous and suitable for parameter measurements under this subpart. If the batch is not homogeneous, increase mixing or take other appropriate steps and repeat the procedure.

(b) Draw a sample representing different levels of stored fuel, fuel additive, or regulated blendstock in the tank as specified in § 1090.1335(b)(1).

(c) For testing to meet the gasoline standards in subpart C of this part, demonstrate homogeneity using two of the procedures specified in paragraph (c)(1) through (4) of this section. For summer gasoline, the homogeneity demonstration must include RVP measurements.

(1) Measure API gravity from each sample using ASTM D287, ASTM D1298, or ASTM D4052 (incorporated by reference in § 1090.95).

(2) Measure the sulfur content of each sample as specified in this subpart.

(3) Measure the benzene content of each sample as specified in this subpart.

(4) Measure the RVP of each sample as specified in this subpart.

(d) For testing to meet the diesel fuel standards in subpart D of this part, demonstrate homogeneity using one of the procedures specified in paragraph (c)(1) or (2) of this section.

(e) Consider the batch to be homogeneous for a given parameter if the measured values for all tested samples vary by less than the published repeatability of the test method. If repeatability is a function of measured values, calculate repeatability using the average value of the measured parameter representing all tested samples. Calculate using all meaningful significant figures as specified for the test method, even if § 1090.1350(c) describes a different precision. For cases that do not require a homogeneity demonstration under § 1090.1335(b)(4), the lack of homogeneity demonstration does not prevent a quantity of fuel, fuel additive, or regulated blendstock from being considered a batch for demonstrating compliance with the requirements of this part.

§ 1090.1340
Preparing a hand blend from BOB.

(a) If you produce or import BOB and instruct downstream blenders to add oxygenate, you must meet the sampling requirements of this subpart by blending oxygenate into a BOB sample to represent the final blended fuel. To do this, prepare each fuel sample by adding oxygenate to the BOB sample in a way that corresponds to your instructions to downstream blenders for the sampled batch of fuel. Prepare a hand blend representing a worst case for oxygenate as follows:

(1) Take steps to avoid introducing high or low bias in sulfur content when selecting from available samples to create the hand blend. For example, if there are three samples with discrete sulfur measurements, select the sample with the mid-range sulfur content. In other cases, randomly select the sample.

(2) If your instructions allow for downstream blenders to add more than one type or concentration of oxygenate, prepare a hand blend for summer gasoline intended for blending with ethanol using the lowest specified ethanol blend. For summer gasoline intended for blending only with oxygenate other than ethanol, and for all winter gasoline, blend at the lowest specified oxygenate concentration, regardless of the type of oxygenate. For example, if you give instructions for a given batch of BOB to perform downstream blending to make E10, E15, and an 8 percent blend with butanol, prepare a hand blend for testing winter gasoline with 8 percent butanol, and prepare an E10 hand blend for testing summer gasoline.

(b) Blend the fuel using the procedures specified in ASTM D7717 (incorporated by reference in § 1090.95). The blended fuel must have an amount of oxygenate that does not exceed the oxygenate concentration specified on the PTD for the BOB under § 1090.1160(b)(1).

(c) If you produce or import BOB and you blend in oxygenate before selling or transporting the fuel, you must instead draw samples from your blended fuel.

§ 1090.1345
Retaining samples.

(a) Fuel manufacturers, regulated blendstock producers, and independent surveyors must retain samples of fuel and oxygenate tested under this subpart as follows:

(1) If you test gasoline, diesel fuel, or oxygenate to measure any parameter as required under this subpart, you must keep a representative fuel sample for at least 30 days after testing is complete, except that a longer sample retention of 120 days applies for blending manufacturers that produce gasoline.

(2) The nominal volume of retained samples must be at least 330 ml. If you have only a single sample for testing, keep that sample after testing is complete. If you collect multiple samples from a single batch or you create a hand blend, select a representative sample as follows:

(i) If you test a hand blend under § 1090.1340, keep a sample of the BOB.

(ii) For summer gasoline, keep an untested (or less tested) sample that is most like the tested sample, as applicable. In all other cases, keep the tested (or most tested) sample.

(b) Oxygenate producers and importers must keep oxygenate samples as follows:

(1) Keep a representative sample of any tested oxygenate. Also keep a representative sample of DFE if you used the provisions of § 1090.1330 to calculate its sulfur content. The nominal volume of retained samples must be at least 330 ml.

(2) Keep all the samples you collect over the previous 21 days. If you have fewer than 20 samples from the previous 21 days, continue keeping the most recent 20 samples collected up to a maximum of 90 days for any given sample.

(c) Keep records of all calculations, test results, and test methods for the batch associated with each stored sample.

(d) If EPA requests a test sample, you must follow EPA's instructions and send it to EPA by a courier service (or equivalent). The instructions will describe where and when to send the sample. For each test sample, you must identify the test results and test methods used.

(e) You are responsible for meeting the requirements of this section even if a third party performs testing and stores the fuel samples for you.

Measurement Procedures

§ 1090.1350
Overview of test procedures.

Fuel manufacturers meet the requirements of this subpart based on laboratory measurements of the specified fuel parameters. Test procedures for these measurements apply as follows:

(a) Except as specified in paragraph (b) of this section, the Performance-based Measurement System specified in §§ 1090.1360 through 1090.1375 applies for all testing specified in this subpart for the following fuels and fuel parameters:

(1) Sulfur content of diesel fuel.

(2) Sulfur content of ECA marine fuel.

(3) RVP, sulfur content, benzene content, and oxygenate content of gasoline. The procedures for measuring sulfur in gasoline in this subpart also apply for testing sulfur in certified ethanol denaturant; however, demonstrating compliance for alternative procedures in § 1090.1365 and statistical quality control in § 1090.1375 do not apply for sulfur concentration above 80 ppm.

(4) Sulfur content of butane.

(b) Specific test procedures apply for measuring other fuel parameters, as follows:

(1) Determine the cetane index of diesel fuel as specified in ASTM D976 or ASTM D4737 (incorporated by reference in § 1090.95). There is no cetane-related test requirement for biodiesel.

(2) Measure aromatic content of diesel fuel as specified in ASTM D1319 or ASTM D5186 (incorporated by reference in § 1090.95). You may use an alternative procedure if you correlate your test results with ASTM D1319 or ASTM D5186.

(3) Measure the purity of butane and pentane as specified in ASTM D2163 (incorporated by reference in § 1090.95).

(4) Measure the benzene content of butane and pentane as specified in ASTM D5134 (incorporated by reference in § 1090.95).

(5) Measure the sulfur content of pentane as specified in ASTM D6667 (incorporated by reference in § 1090.95).

(6) Measure distillation parameters of gasoline as specified in ASTM D86 (incorporated by reference in § 1090.95). You may use an alternative procedure if you correlate your test results with ASTM D86.

(7) Measure the sulfur content of neat ethanol as specified in ASTM D5453 (incorporated by reference in § 1090.95). You may use an alternative procedure if you correlate your test results with ASTM D5453.

(8) Measure the phosphorus content of gasoline as specified in ASTM D3231 (incorporated by reference in § 1090.95).

(9) Measure the lead content of gasoline as specified in ASTM D3237 (incorporated by reference in § 1090.95).

(10) Measure the sulfur content of gasoline additives and diesel fuel additives as specified in ASTM D2622 (incorporated by reference in § 1090.95).

(11) Use referee procedures specified in § 1090.1360(d) and the following additional methods to measure gasoline fuel parameters to meet the survey requirements of subpart N of this part:

Open Table

Table 1 to Paragraph (b)(11)

Fuel parameter Units Test method 1
Distillation (T50 and T90) °C ASTM D86.
Aromatic content volume percent ASTM D5769.
Olefin content volume percent ASTM D6550.
1 ASTM specifications are incorporated by reference in § 1090.95.

(12) Updated versions of the test procedures specified in this section are acceptable as alternative procedures if both repeatability and reproducibility are at least as precise as the values specified in the earlier version.

(c) Record measured values with the following precision, with rounding in accordance with § 1090.50:

(1) Record sulfur content to the nearest whole ppm.

(2) Record benzene to the nearest 0.01 volume percent.

(3) Record RVP to the nearest 0.01 psi.

(4) Record oxygenate content to the nearest 0.01 mass percent for each calibrated oxygenate.

(5) Record diesel aromatic content to the nearest 0.1 volume percent, or record cetane index to the nearest whole number.

(6) Record gasoline aromatic and olefin content to the nearest 0.1 volume percent.

(7) Record distillation parameters to the nearest whole degree.

(d) For any measurement or calculation that depends on the volume of the test sample, correct the volume of the sample to a reference temperature of 15.5 °C (288.65 K). Use a correction equation that is appropriate for each tested compound. This applies for all fuels, blendstocks, and additives, except butane.

§ 1090.1355
Calculation adjustments and corrections.

Adjust measured values for special circumstances as follows:

(a) Adjust measured values for total vapor pressure as follows:

RVP (psi) = 0.956 • Ptotal − 0.347

Where:

Ptotal = Measured total vapor pressure, in psi.

(b) For measuring the sulfur and benzene content of gasoline, adjust a given test result upward in certain circumstances, as follows:

(1) If your measurement method involves a published procedure with a Pooled Limit of Quantitation (PLOQ), treat the PLOQ as your final result if your measured result is below the PLOQ.

(2) If your measurement method involves a published procedure with a limited scope but no PLOQ, treat the lower bound of the scope as your final result if your measured result is less than that value.

(3) If you establish a Laboratory Limit of Quantitation (LLOQ) below the lower bound of the scope of the procedure as specified in ASTM D6259 (incorporated by reference in § 1090.95), treat the LLOQ as your final result if your measured result is less than the LLOQ. Note that this option is meaningful only if the LLOQ is less than a published PLOQ, or if there is no published PLOQ.

(c) For measuring the benzene content of butane and pentane, report a zero value if the test result is at or below the PLOQ or Limit of Detection (LOD) that applies for the test method.

(d) If measured content of any oxygenate compound is less than 0.1 percent by mass, record the result as “None detected.”

§ 1090.1360
Performance-based Measurement System.

(a) The Performance-based Measurement System (PBMS) is an approach that allows for laboratory testing with any procedure that meets specified performance criteria. This subpart specifies the performance criteria for measuring certain fuel parameters to demonstrate compliance with the standards and other specifications of this part. These provisions do not apply to process stream analyzers used with in-line blending.

(b) Different requirements apply for absolute fuel parameters and method-defined fuel parameters.

(1) Absolute fuel parameters are those for which it is possible to evaluate measurement accuracy by comparing measured values of a test sample to a reference sample with a known value for the measured parameter. The following are absolute fuel parameters:

(i) Sulfur. This applies for measuring sulfur in any fuel, fuel additive, or regulated blendstock.

(ii) [Reserved]

(2) Method-defined fuel parameters are all those that are not absolute fuel parameters. Additional test provisions apply for method-defined fuel parameters under this section because there is no reference sample for evaluating measurement accuracy.

(c) The performance criteria of this section apply as follows:

(1) Section 1090.1365 specifies the initial qualifying criteria for all measurement procedures. You may use an alternative procedure only if testing shows that you meet the initial qualifying criteria

(2) Section 1090.1375 specifies ongoing quality testing requirements that apply for laboratories that use either referee procedures or alternative procedures.

(3) Streamlined requirements for alternative procedures apply for procedures adopted by a voluntary consensus standards body (VCSB). Compliance testing with non-VCSB procedures requires advance approval by EPA. Procedures are considered non-VCSB testing as follows:

(i) Procedures developed by individual companies or other parties are considered non-VCSB procedures.

(ii) Draft procedures under development by a VCSB organization are considered non-VCSB procedures until they are approved for publication.

(iii) A published procedure is considered non-VCSB for testing with fuel parameters that fall outside the range of values covered in the research report of the ASTM D6708 (incorporated by reference in § 1090.95) assessment comparing candidate alternative procedures to the referee procedure specified in paragraph (d) of this section.

(4) You may qualify updated versions of the referee procedures as alternative procedures under § 1090.1365. You may ask EPA for approval to use an updated version of the referee procedure for qualifying other alternative procedures if the updated referee procedure has the same or better accuracy and precision compared to the version specified in § 1090.95. If the updated procedure has worse accuracy and precision compared to the earlier version, you must complete the required testing specified in § 1090.1365 using the older, referenced version of the referee procedure.

(5) Any laboratory may use the specified referee procedure without qualification testing. To use alternative procedures at a given facility, you must perform the specified testing to demonstrate compliance with precision and accuracy requirements, with the following exceptions:

(i) Testing you performed to qualify alternative procedures under 40 CFR part 80 continues to be valid for making the demonstrations required in this part.

(ii) Qualification testing is not required for laboratories that measure the benzene content of gasoline using Procedure B of ASTM D3606 (incorporated by reference in § 1090.95). However, qualification testing may be necessary for updated versions of this procedure as specified in § 1090.1365(a)(2).

(d) Referee procedures are presumed to meet the initial qualifying criteria in this section. You may use alternative procedures if you qualify them using the referee procedures as a benchmark as specified in § 1090.1365. The following are the referee procedures:

Open Table

Table 1 to Paragraph (d)

Tested product Parameter Referee procedure 1
ULSD, 500 ppm diesel fuel, ECA marine fuel, gasoline Sulfur ASTM D2622.
Butane Sulfur ASTM D6667.
Gasoline oxygenate content ASTM D5599.
Gasoline RVP ASTM D5191, except as specified in § 1090.1355(a).
Gasoline benzene ASTM D5769.
1 ASTM specifications are incorporated by reference in § 1090.95.
§ 1090.1365
Qualifying criteria for alternative measurement procedures.

This section specifies how to qualify alternative procedures for measuring absolute and method-defined fuel parameters under the Performance-based Analytical Test Method specified in § 1090.1360.

(a) The following general provisions apply for qualifying alternative procedures:

(1) Alternative procedures must have appropriate precision to allow for reporting to the number of decimal places specified in § 1090.1350(c).

(2) Testing to qualify an alternative procedure applies for the specified version of the procedure you use for making the necessary measurements. Once an alternative procedure for a method-defined fuel parameter is qualified for your laboratory, updated versions of that same procedure are qualified without further testing, as long as the procedure's specified reproducibility is the same as or better than the values specified in the earlier version. For absolute fuel parameters, updated versions are qualified without testing if both repeatability and reproducibility are the same as or better than the values specified in the earlier version.

(3) Except as specified in paragraph (d) of this section, testing to demonstrate compliance with the precision and accuracy specifications in this section apply only for the test facility where the testing occurred.

(4) If a procedure for measuring benzene or sulfur in gasoline has no specified PLOQ and no specified scope with a lower bound, you must establish a LLOQ for your facility.

(5) Testing for method-defined fuel parameters must take place at a reference installation as specified in § 1090.1370.

(b) All alternative procedures must meet precision criteria based on a calculated maximum allowable standard deviation for a given fuel parameter as specified in this paragraph. The precision criteria apply for measuring the parameters and fuels specified in paragraph (b)(3) of this section. Take the following steps to qualify the measurement procedure for measuring a given fuel parameter:

(1) The fuel must meet the parameter specifications in Table 1 to paragraph (b)(3) of this section. This may require that you modify the fuel you typically produce to be within the specified range. Absent a specification (maximum or minimum), select a fuel representing values that are typical for your testing. Store and mix the fuel to maintain a homogenous mixture throughout the measurement period to ensure that each fuel sample drawn from the batch has the same properties.

(2) Measure the fuel parameter from a homogeneous fuel batch at least 20 times. Record each result in sequence. Do not omit any valid results unless you use good engineering judgment to determine that the omission is necessary and you document those results and the reason for excluding them. Perform this analysis over a 20-day period. You may make up to 4 separate measurements in a 24-hour period, as long as the interval between measurements is at least 4 hours. Do not measure RVP more than once from a single sample.

(3) Calculate the maximum allowable standard deviation as follows:

Where:

σmax = Maximum allowable standard deviation.

x1, x2, and x3 have the values from the following table:

2 ASTM publications are incorporated by reference in § 1090.95. Note that the listed procedure may be different than the referee procedure identified in § 1090.1360(d), or it may be an older version of the referee procedure.
3 Use only 1-liter containers for testing to qualify alternative methods.

(c) Alternative VCSB procedures for measuring absolute fuel parameters (sulfur) must meet accuracy criteria based on the following measurement procedure:

(1) Obtain gravimetric sulfur standards to serve as representative reference samples. The samples must have known sulfur content within the ranges specified in paragraph (c)(3) of this section. The known sulfur content is the accepted reference value (ARV) for the fuel sample.

(2) Measure the sulfur content of the fuel sample at your laboratory at least 10 times, without interruption. Use good laboratory practice to compensate for any known chemical interferences; however, you must apply that same compensation for all tests to measure the sulfur content of a test fuel. Calculate the arithmetic average of all the measured values, including any compensation.

(3) The measurement procedure meets the accuracy requirement as follows:

(i) Demonstrate accuracy for measuring sulfur in gasoline, gasoline regulated blendstock, and gasoline additive using test fuels to represent sulfur values from 1 to 10 ppm, 11 to 20 ppm, and 21 to 95 ppm. You may omit any of these ranges if you do not perform testing with fuel in that range. Calculate the maximum allowable difference between the average measured value and ARV for each applicable range as follows:

Δmax = 0.75· σmax

Where:

Δmax = Maximum allowable difference.

σmax = the maximum allowable standard deviation from paragraph (b)(3) of this section using the sulfur content represented by ARV.

(ii) Demonstrate accuracy for measuring sulfur in diesel fuel using test fuels meeting the specifications in Table 2 to this section. For testing diesel-related blendstocks and additives, use representative test samples meeting the appropriate sulfur specification. Table 2 to paragraph (c)(3)(ii) of this section also identifies the maximum allowable difference between average measured values and ARV corresponding to ARV at the upper end of the specified ranges. These values are based on calculations with the equation in paragraph (c)(3)(i) of this section, with parameter values set to be equal to the standard.

Open Table

Table 2 to Paragraph (c)(3)(ii)—Accuracy Criteria for Qualifying Alternative Procedures with Diesel Fuel and Diesel-Related Blendstocks and Additives

Fuel Sulfur content (ppm) Illustrated maximum allowable differences
ULSD 10-20 0.54
500 ppm LM diesel fuel 450-500 8.65
ECA marine fuel 900-1,000 15.1

(d) Alternative VCSB procedures for measuring method-defined fuel parameters must meet accuracy criteria as follows:

(1) You may use the alternative procedure only if you follow all the statistical protocols and meet all the criteria specified in Section 6 of ASTM D6708 (incorporated by reference in § 1090.95) when comparing your measurements using the alternative procedure to measurements at a reference installation using the appropriate referee test method identified in § 1090.1360(d).

(2) For qualifying alternative procedures, determine whether the alternative procedure needs a correlation equation to correct bias relative to the reference test method. Create such a correlation equation as specified in Section 7 of ASTM D6708. For all testing, apply the correlation equation to adjust measured values to be statistically consistent to measuring with the reference test method.

(3) If an alternative VCSB procedure states that the procedure has a successful assessment relative to the referee procedures in this section under ASTM D6708, that finding applies for all test facilities using that procedure.

(e) Alternative non-VCSB procedures for measuring absolute fuel parameters (sulfur) must meet accuracy criteria as follows:

(1) Demonstrate whether the procedure meets statistical criteria and whether it needs a correlation equation as specified in paragraphs (d)(1) and (2) of this section. Apply the correlation equation for all testing with the alternative procedure.

(2) Demonstrate at your laboratory that the alternative procedure meets the accuracy criteria specified in paragraph (c) of this section.

(3) Send EPA a written request to use the alternative procedure. In your request, fully describe the procedure to show how it functions for achieving accurate measurements and include detailed information related to your assessment under paragraph (d)(1) and (2) of this section.

(f) Alternative non-VCSB procedures for measuring method-defined fuel parameters must meet accuracy and precision criteria as follows:

(1) Demonstrate whether the procedure meets statistical criteria and whether it needs a correlation equation as specified in paragraphs (d)(1) and (2) of this section. Apply the correlation equation for all testing with the alternative procedure.

(2) Test with a range of fuels that are typical of those you will analyze at your laboratory. Use either consensus-named fuels or locally-named reference materials. Consensus-named fuels are homogeneous fuel quantities sent around to different laboratories for analysis, which results in a “consensus name” representing the average value of the parameter for all participating laboratories. Locally named reference materials are fuel samples analyzed using the reference test method, either at your laboratory or at a reference installation, to establish an estimated value for the fuel parameter; locally named reference materials usually come from the fuel you produce.

(3) You may qualify your procedure as meeting the variability requirements of paragraph (f)(1) of this section only for a narrower, defined range of fuels. If this is the case, identify the appropriate range of fuels in your request for approval and describe how you will screen fuel samples accordingly.

(4) Qualify the precision of the alternative procedure by comparing results to testing with the referee procedure based on “between methods reproducibility,” Rxy, as specified in ASTM D6708. The Rxy must be at or below 75 percent of the reproducibility of the referee procedure from § 1090.1360(d).

(5) Perform testing at your laboratory as specified in paragraph (b) of this section to establish the repeatability of the alternative procedure. The repeatability must be as good as or better than that specified in paragraph (b)(3) of this section.

(6) Fully describe the procedure to show how it functions for achieving accurate measurements. Describe the technology, test instruments, and testing method so a competent person lacking experience with the procedure and test instruments would be able to replicate the results.

(7) Engage a third-party auditor to review and verify your information as follows:

(i) The auditor must qualify as an independent third party and meet the specifications for technical ability as specified in § 1090.55.

(ii) The auditor must send you a report describing their inspection of your facilities and their review of the information supporting your request to use the alternative procedure. The report must describe how the auditor performed the review, identify any errors or discrepancies, and state whether the information supports a conclusion that the alternative procedure should be approved.

(iii) The auditor must keep records related to the review for at least 5 years after sending you the report and provide those records to EPA upon request.

(8) Send EPA a written request to use the alternative procedure. Include the specified information and any additional information EPA needs to evaluate your request.

(g) Keep fuel samples from any qualification testing under this section for at least 180 days after you have taken all steps to qualify an alternative procedure under this section. This applies for testing at your laboratory and at any reference installation you use for demonstrating the accuracy of an alternative procedure.

§ 1090.1370
Qualifying criteria for reference installations.

(a) A reference installation refers to a test facility that uses the referee test method specified in § 1090.1360(d) to evaluate the accuracy of alternative procedures for method-defined parameters, by comparing measured values to companion tests using one of the referee procedures in § 1090.1360(d). This evaluation may result in an equation to correlate results between the two procedures. Once a facility qualifies as a reference installation, that qualification is valid for five years from the qualifying date, consistent with good laboratory practices.

(b) Qualify a reference installation for VCSB procedures by participating in an interlaboratory crosscheck program with at least 16 separate measurements that are not identified as outliers. This presumes that the results for the candidate reference installation are not outliers.

(c) Qualify a reference installation for non-VCSB procedures based on the following measurement protocol:

(1) Use the precision testing procedure specified in § 1090.1365(b) to show that your standard deviation for tests using the reference test method is at or below 0.3 times the reproducibility for a given fuel parameter.

(2) You must correlate your test results for a given fuel parameter against the accepted reference values from a monthly crosscheck program based on Section 6.2.2.1 and Note 7 of ASTM D6299 (incorporated by reference in § 1090.95) as follows:

(i) If there are multiple fuels available from the crosscheck program, select the fuel that has the closest value to the standard. If there is no standard for a given fuel parameter, select the fuel with values for the fuel parameter that best represent typical values for fuels you test.

(ii) Measure the fuel parameter for the crosscheck fuel at your facility using the appropriate referee procedure. Calculate a mean value that includes all your repeat measurements.

(iii) Determine the mean value from the crosscheck program and calculate the difference between this value and the mean value from your testing. Express this difference as a certain number of standard deviations relative to the data set from the crosscheck program.

(iv) The calculated monthly difference between the mean values from § 1090.1365(c)(3)(ii) for 5 consecutive months must fall within the central 50 percent of the distribution of data at least 3 times. The central 50 percent of the distribution corresponds to 0.68 standard deviations.

(v) Calculate the mean value of the differences from § 1090.1365(c)(3)(ii) for all 5 months. This mean value must fall within the central 50 percent of the distribution of data from the crosscheck program. For example, if the difference was 0.5 standard deviations for two months, 0.6 for one month, and 0.7 for two months, the mean value of the difference is 0.6 standards deviations, and the reference installation meets the requirements of this paragraph.

(3) You must demonstrate that the reference installation is in statistical quality control for at least 5 months with the designated procedure as specified in ASTM D6299 (incorporated by reference in § 1090.95). If at any point the reference installation is not in statistical quality control, you must make any necessary changes and restart testing toward meeting the requirement to achieve statistical quality control for at least 5 months, except as follows:

(i) Do not consider measurements you perform as part of regular maintenance or recalibration for evaluating statistical quality control.

(ii) If you find that the reference installation is not in statistical quality control during an initial 5-month period and you are able to identify the problem and make the necessary changes to again achieve statistical quality control before the end of the 5-month demonstration period, you may consider the reference installation as meeting the requirement to be in statistical quality control for at least 5 months.

§ 1090.1375
Quality control procedures.

This section specifies ongoing quality testing requirements as part of the Performance-based Measurement System specified in § 1090.1360.

(a) General provisions. You must perform testing to show that your test facility meets specified precision and accuracy criteria as follows:

(1) The testing requirement applies for the referee procedures in § 1090.1360(d) and for alternate procedures that are qualified or approved under § 1090.1365. The testing requirements apply separately for each test instrument at each test facility.

(2) If you fail to conduct specified testing, your test facility is not qualified for measuring fuel parameters to demonstrate compliance with the standards and other specifications of this part until you perform this testing. Similarly, if your test facility fails to meet the specified criteria, it is not qualified for measuring fuel parameters to demonstrate compliance with the standards and other specifications of this part until you make the necessary changes to your test facility and perform testing to show that the test facility again meets the specified criteria.

(3) If you perform major maintenance such as overhauling an instrument, confirm that the instrument still meets precision and accuracy criteria before you start testing again based on the procedures specified in ASTM D6299 (incorporated by reference in § 1090.95).

(4) Keep records to document your testing under this section for 5 years.

(b) Precision demonstration. Show that you meet precision criteria as follows:

(1) Meeting the precision criteria of this paragraph (b) qualifies your test facility for performing up to 20 production tests or 7 days, whichever is less.

(2) Perform precision testing using the control-chart procedures in ASTM D6299. If you opt to use the Q-procedure, validate the first run on the new QC batch by either an overlap in-control result of the old batch, or by a single execution of an accompanying standard reference material. The new QC material result would be considered validated if the single result of the standard reference material is within the established site precision (R') of the ARV of the standard reference material, as determined by ASTM D6792 (incorporated by reference in § 1090.95).

(3) Use I charts and MR charts as specified in ASTM D6299 to show that the long-term standard deviation for the test facility meets the precision criteria specified in § 1090.1365(b).

(c) Accuracy demonstration. For absolute fuel parameters (VCSB and non-VCSB) and for method-defined fuel parameters using non-VCSB methods, you must show that you meet accuracy criteria as specified in this paragraph. For method-defined VCSB procedures, you may meet accuracy requirements as specified in this paragraph or by comparing your results to the accepted reference value in an inter-laboratory crosscheck program sponsored by ASTM International or another VCSB at least 3 times per year.

(1) Meeting the accuracy criteria of this paragraph (c) qualifies your test facility for 130 days.

(2) Except as specified in paragraph (c)(3) of this section, test every instrument using a check standard meeting the specifications of ASTM D6299. Select a fuel sample with an ARV that is at or slightly below the standard that applies. If there are both average and batch standards, use the average standard. If there is no standard, select a fuel sample representing fuel that is typical for your testing.

(3) The following provisions apply for method-defined non-VCSB alternative procedures with high sensitivity to sample-specific bias:

(i) Procedures have high sensitivity if the closeness sum of squares (CSS) statistic exceeds the 95th percentile value, as specified in ASTM D6708 (incorporated by reference in § 1090.95).

(ii) Create a check standard from production fuel representing the fuel you will routinely analyze. Determine the ARV of your check standard using the protocol in ASTM D6299 at a reference installation as specified in § 1090.1370.

(iii) You must send EPA a fuel sample from every twentieth batch of gasoline or diesel fuel and identify the procedures and corresponding test results from your testing. EPA may return one of your samples to you for further testing; if this occurs, you must repeat your measurement and report your results within 180 days of receiving the fuel sample.

(4) You meet accuracy requirements under this section if the difference between your measured value for the check standard and the ARV is less than the value from the following equation:

Where:

Δmax = Maximum allowable difference.

R = Reproducibility of the referee procedure identified in § 1090.1360(d), as noted in Table 1 to paragraph (b)(3) of § 1090.1365 or in the following table:

Testing Related to Gasoline Deposit Control

§ 1090.1390
Requirement for Automated Detergent Blending Equipment Calibration.

(a) Automated detergent blending facilities must calibrate their automated detergent blending equipment once in each calendar half-year, with the acceptable calibrations being no less than 120 days apart.

(b) Equipment recalibration is also required each time the detergent package is changed, unless written documentation indicates that the new detergent package has the same viscosity as the previous detergent package. Calibrating after changing the detergent package may be used to satisfy the semiannual recalibration requirement in paragraph (a) of this section, provided that the calibrations occur in the appropriate calendar half-year and are no less than 120 days apart.

§ 1090.1395
Gasoline deposit control test procedures.

Gasoline detergent manufacturers must perform testing as specified in paragraph (a), (b), or (c) of this section to establish the lowest additive concentration (LAC) for the detergent.

(a) Top Tier-Based Test Method. Use the procedures specified in ASTM D6201 (incorporated by reference in § 1090.95), as follows:

(1) Use a base fuel that conforms to the specifications for gasoline-alcohol blends in ASTM D4814 (incorporated by reference in § 1090.95). Blendstocks used to formulate the test fuel must be derived from conversion units downstream of distillation, with all processes representing normal fuel manufacturing facility operations. Blendstocks may not come from chemical grade streams. Butane and pentane may be added to adjust vapor pressure. The base fuel should include any nondetergent additives typical of commercially available fuel if they may positively or negatively affect deposit formation. In addition, the base fuel must have the following properties:

(i) 8.0-10.0 Volume percent DFE that meets the requirements in § 1090.230 and conforms to the specifications of ASTM D4806 (incorporated by reference in § 1090.95).

(ii) At least 8.0 volume percent olefins.

(iii) At least 15 volume percent aromatics.

(iv) No more than 80 ppm sulfur.

(v) T90 distillation temperature at or above 143 °C.

(vi) No detergent-active substance. A base fuel with typical nondetergent additives, such as antioxidants, corrosion inhibitors, and metal deactivators, may be used.

The same retail outlet may represent both a gasoline retail outlet and a diesel fuel retail outlet for purposes of determining the number of samples.

(2) The minimum number of samples to be included in the survey plan for each calendar year is calculated as follows:

Where:

n = Minimum number of samples in a year-long survey series. However, n must be greater than or equal to 2,000 for the number of diesel samples or 5,000 for the number of gasoline samples.

Zα = Upper percentile point from the normal distribution to achieve a one-tailed 95% confidence level (5% α-level). For purposes of this survey program, Zα equals 1.645.

Zβ = Upper percentile point to achieve 95% power. For purposes of this survey program, Zβ equals 1.645.

ϕ1 = The maximum proportion of non-compliant outlets for a region to be deemed compliant. This parameter needs to be 5% or greater (i.e., 5% or more of the outlets, within a stratum such that the region is considered non-compliant).

ϕ0 = The underlying proportion of non-compliant outlets in a sample. For the first survey plan, ϕ0 will be 2.3%. For subsequent survey plans, ϕ0 will be the average of the proportion of outlets found to be non-compliant over the previous 4 surveys.

Fa = Adjustment factor for the number of extra samples required to compensate for samples that could not be included in the survey (e.g., due to technical or logistical considerations), based on the number of additional samples required during the previous 4 surveys. Fa must be greater than or equal to 1.1.

Fb = Adjustment factor for the number of samples required to resample each retail outlet with test results reported to EPA under § 1090.1410(e), based on the rate of resampling required during the previous 4 surveys. Fb must be greater than or equal to 1.1.

Sun = Number of surveys per year. For purposes of this survey program, Sun equals 4.

Stn = Number of sampling strata. For purposes of this survey program, Stn equals 3.

(3) The number of gasoline samples that also need to be tested for aromatics, olefins, and distillation parameters under § 1090.1410(c)(2) must be calculated using the methodology specified in paragraph (e)(2) of this section without the Fa, Fb, and Sun parameters.

(4) The number of samples determined under paragraphs (e)(2) and (3) of this section must be distributed approximately equally among the 4 surveys conducted during the calendar year.

(b) Importers that import fuel at multiple import facilities must comply with the gasoline average standards as specified in § 1090.705(b) unless the importer elects to comply with the alternative per-gallon standards for rail and truck imports specified in §§ 1090.205(d) and 1090.210(c).

(c) Importers must separately comply with any applicable certification or other requirements for U.S. Customs.

(d) Alternative testing requirements for importers that import gasoline or diesel fuel by rail or truck are specified in § 1090.1610.

§ 1090.1605
Importation by marine vessel.

Importers that import fuel, fuel additive, or regulated blendstock using a marine vessel must comply with the requirements of this section.

(a) Importers must certify each fuel, fuel additive, or regulated blendstock imported at each port, even if it is transported by the same vessel making multiple stops.

(b)(1) Except as specified in paragraph (d) of this section, importers must certify each fuel, fuel additive, or regulated blendstock while it is onboard the vessel used to transport it to the United States, and certification sampling must be performed after the vessel's arrival at the port where the fuel, fuel additive, or regulated blendstock will be offloaded.

(2) Importers must sample each compartment of the vessel and treat each compartment as a separate batch unless the importer collects and combines samples from separate compartments into a single, volume-weight composite sample using ASTM D4057 (incorporated by reference in § 1090.95) and demonstrates that the fuel, fuel additive, or regulated blendstock is homogeneous across the compartments under § 1090.1337.

(3) Importers must ensure that all applicable per-gallon standards are met before offloading the fuel, fuel additive, or regulated blendstock.

(4) Importers must not rely on testing conducted by a foreign supplier.

(c) Once the fuel, fuel additive, or regulated blendstock on a vessel has been certified under paragraph (b) of this section, it may be transferred to shore tanks using smaller vessels or barges (lightered) as a certified fuel, fuel additive, or regulated blendstock. These lightering transfers may be to terminals located in any harbor and are not restricted to terminals located in the harbor where the vessel is anchored. For example, certified gasoline could be transferred from an import vessel anchored in New York harbor to a lightering vessel and transported to Albany, New York or Providence, Rhode Island without separately certifying the gasoline upon arrival in Albany or Providence. In this lightering scenario, transfers of certified gasoline to a lightering vessel must be accompanied by PTDs that meet the PTD requirements of subpart K of this part.

(d) As an alternative to paragraphs (b) and (c) of this section, importers may offload fuel, fuel additive, or regulated blendstock into shore tanks containing the same fuel, fuel additive, or regulated blendstock if the importer meets the following requirements:

(1) For gasoline, importers must offload gasoline into one or more empty shore tanks or tanks containing PCG that the importer owns.

(i) If importers offload gasoline into one or more empty shore tanks, they must sample and test the sulfur and benzene content, and for summer gasoline, RVP, of each shore tank into which the gasoline was offloaded.

(ii) If importers offload gasoline into one or more shore tanks containing PCG, they must sample the PCG already in the shore tank prior to offloading gasoline from the marine vessel, test the sulfur and benzene content, and report this PCG as a batch with a negative volume. After offloading the gasoline into the shore tanks, the importer must sample and test the sulfur and benzene content, and RVP for summer gasoline, of each shore tank into which the gasoline was offloaded and report the volume and sulfur and benzene content as a positive batch.

(2) For all other fuel, fuel additive, or regulated blendstock, importers must sample and test the fuel, fuel additive, or regulated blendstock in each shore tank into which it was offloaded. Importers must ensure that all applicable per-gallon standards are met before the fuel, fuel additive, or regulated blendstock is shipped from the shore tank.

§ 1090.1610
Importation by rail or truck.

Importers that import fuel, fuel additive, or regulated blendstock by rail or truck may meet the sampling and testing requirements of subpart M of this part based on test results from the supplier if they meet all the following requirements:

(a) The importer must get documentation of test results from the supplier for each batch of fuel, fuel additive, or regulated blendstock in accordance with the following requirements:

(1) The testing must include measurements for all the fuel parameters specified in § 1090.1310 using the measurement procedures specified in § 1090.1350.

(2) Testing for a given batch must occur after the most recent delivery into the supplier's storage tank and before transferring the fuel, fuel additive, or regulated blendstock to the railcar or truck.

(b) The importer must conduct testing to verify test results from each supplier as follows:

(1) Collect a sample at least once every 30 days or every 50 rail or truckloads from a given supplier, whichever is more frequent. Test such samples as specified in paragraphs (a)(1) and (2) of this section.

(2) Treat importation of each fuel, fuel additive, or regulated blendstock separately, but treat railcars and truckloads together if the fuel, fuel additive, or regulated blendstock is imported from a given supplier by rail and truck.

(c) If the importer fails to meet the requirements of paragraphs (a) and (b) of this section, they must perform testing as specified in § 1090.1310 until EPA determines that the importer has adequately addressed the cause of the failure.

§ 1090.1615
Gasoline treated as a blendstock.

(a) Importers may exclude GTAB from their compliance calculations if they meet all the following requirements:

(1) The importer reports such GTAB to EPA under § 1090.905(c)(7).

(2) Such GTAB is treated as blendstock at a related gasoline manufacturing facility that produces gasoline using the GTAB.

(3) The related gasoline manufacturing facility must report the gasoline produced using such GTAB and must include the gasoline produced using such GTAB in their compliance calculations.

(b) After importation, the title of the GTAB may not be transferred to another party until the GTAB has been blended to produce gasoline and all applicable standards and requirements have been met for the gasoline produced.

(c) The facility at which the GTAB is used to produce gasoline must be physically located at either the same terminal at which the GTAB first arrives in the United States, the import facility, or at a facility to which the GTAB is directly transported from the import facility.

(d)(1) The importer must treat the GTAB as if were imported gasoline and complete all requirements for gasoline manufacturers under § 1090.105(a) (except for the sampling, testing, and sample retention requirements in § 1090.105(a)(5)) for the GTAB at the time it is imported.

(2) Any GTAB that ultimately is not used to produce gasoline (e.g., a tank bottom of GTAB) must be treated as newly imported gasoline and must meet all applicable requirements for imported gasoline.

§ 1090.1650
General provisions for exporters.

Except as specified in this section and in subpart G of this part, gasoline and diesel fuel produced, imported, distributed, or offered for sale in the United States is subject to the standards and requirements of this part.

(a) Fuels designated for export by a fuel manufacturer are not subject to the standards in this part, provided they are ultimately exported to a foreign country. However, such fuels must be designated at the fuel manufacturing facility and must be accompanied by PTDs stating that the fuel is for “export only” under subpart K of this part. Fuel manufacturers must keep records to demonstrate that the fuel was exported. Fuel designated for export must be segregated from all fuel intended for use in the United States.

(b) Fuel not designated for export may be exported without restriction. However, the fuel remains subject to the provisions of this part while in the United States. For example, fuel designated as ULSD must meet the applicable sulfur standards under this part even if it will later be exported.

(c) Fuel that has been classified as American Goods Returned to the U.S. by the U.S. Customs Service is not considered to be imported for purposes of this part, provided all the following requirements are met:

(1) Such fuel was produced at a fuel manufacturing facility located within the United States and has not been mixed with fuel produced at a fuel manufacturing facility located outside the United States.

(2) Such fuel must be included in compliance calculations by the producing fuel manufacturer.

(3) All the fuel that was exported must ultimately be classified as American Goods Returned to the U.S. and none may be used in a foreign country.

Footnotes

1.  Under the current regulations, EPA's fuels regulations are in 40 CFR parts 79 and 80. Part 79 contains provisions related to the registration of fuel and fuel additives under CAA sections 211(a), (b), (e), and (f), while Part 80 contains provisions for fuel quality (e.g., fuel controls and prohibitions established under CAA section 211(c) and the RFG program requirements promulgated under CAA section 211(k)) and the RFS program. This action is limited to the provisions related to EPA's fuel quality standards in part 80, as the registration requirements in part 79 and the RFS program in part 80 are significantly different in scope and would involve different considerations to update those regulatory requirements.

90.  For batches that are certified using the hand blend approach (discussed in more detail in Section VII.F), oxygenates typically would not be tested; however, gasoline manufacturers would report the type and amount of each oxygenate blended to make the hand blend. Manufacturers that certify batches of gasoline using a different approach would still need to test and report oxygenate content unless they know that the gasoline contains no oxygenate (i.e., the gasoline is E0). Furthermore, in all cases, we would only require that gasoline manufacturers report the oxygenates added or tested for instead of reporting information for all potential oxygenates. We believe this would greatly simplify oxygenate reporting requirements compared to part 80.

Back to Citation

91.  Parties that add more of the same type of oxygenate would not be expected to submit reports for those volumes. For example, under part 1090, if a party only blended 15 volume percent ethanol into a BOB that was specified for blending up to 10 volume percent ethanol, the blender would not submit reports.

95.  The regulations at 40 CFR 80.69 and 80.101 practically limits this practice to RBOB.

In PCG by addition, a blending manufacturer directly measures the parameters of added blendstocks to quantify the sulfur and benzene levels. In both cases, the new fuel has to meet per-gallon specifications for gasoline and blending manufacturers would need to sample and test for sulfur year-round and for RVP in the summer.
