AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule.

SUMMARY:

The Environmental Protection Agency (EPA) is approving most elements of a State Implementation Plan (SIP) revision submitted by the Commonwealth of Massachusetts for the infrastructure requirements for the 2012 fine particle (PM_2.5) National Ambient Air Quality Standard (NAAQS), including the interstate transport requirements. We are making findings of failure to submit for the prevention of significant deterioration (PSD) requirements of infrastructure SIPs for the 2012 PM_2.5 NAAQS. For infrastructure SIP requirements for the 1997 and 2006 PM_2.5 NAAQS, we are also approving previously unaddressed elements and converting certain previous conditional approvals to full approval. We are also converting to full approvals previous conditional approvals for the 1997 and 2008 ozone, 2008 lead, 2010 sulfur dioxide, and 2010 nitrogen dioxide NAAQS. Finally, EPA is approving five new or amended definitions regarding the NAAQS and Particulate Matter and a state Executive Order regarding consultation by state agencies with local governments. This action is being taken in accordance with the Clean Air Act.

DATES:

This rule is effective on July 24, 2019.

I. Background and Purpose

On February 20, 2019 (84 FR 5020), EPA published a Notice of Proposed Rulemaking (NPRM) for the Commonwealth of Massachusetts. This NPRM proposed approval of most elements of a February 9, 2018, submission from the Massachusetts Department of Environmental Protection (MassDEP) regarding the infrastructure SIP requirements of the CAA for the 2012 fine particle (PM_2.5) ^[1] National Ambient Air Quality Standard (NAAQS), including the interstate transport requirements for the 2006 and 2012 PM_2.5 NAAQS. In the NPRM, we also proposed to approve Massachusetts' 2012 PM_2.5 infrastructure SIP submittal for a requirement of prong 3 of CAA section 110(a)(2)(D)(i)(II) related to nonattainment new source review (“NNSR”), based on our proposed approval of revisions to the Commonwealth's NNSR program in a separate, contemporaneous rulemaking. On May 29, 2019, EPA finalized its approval of those NNSR revisions (84 FR 24719). Hence, we may now finalize our approval of Massachusetts' 2012 PM_2.5 submittal for prong 3. In addition, the NPRM proposed approval of the interstate transport requirements for the 1997 PM_2.5 NAAQS, which the Commonwealth submitted on January 31, 2008. Finally, the NPRM proposed to approve a portion of a Massachusetts SIP submission dated May 14, 2018, which included five new or amended definitions in 310 Code of Massachusetts Regulations (CMR) 7.00.

Whenever EPA promulgates a new or revised NAAQS, CAA section 110(a)(1) requires states to make SIP submissions to provide for the implementation, maintenance, and enforcement of the NAAQS. This particular type of SIP submission is commonly referred to as an “infrastructure SIP.” These submissions must meet the various requirements of CAA section 110(a)(2), as applicable. Due to ambiguity in some of the language of CAA section 110(a)(2), EPA believes that it is appropriate to interpret these provisions in the specific context of acting on infrastructure SIP submissions. EPA has previously provided comprehensive guidance on the application of these provisions through a guidance document for infrastructure SIP submissions and through regional actions on infrastructure submissions.^[2] Unless otherwise noted below, we are following that existing approach in acting on this submission. In addition, in the context of acting on such infrastructure submissions, EPA evaluates the submitting state's SIP for facial compliance with statutory and regulatory requirements, not for the state's implementation of its SIP.^[3] The EPA has other authority to address any issues concerning a state's implementation of the rules, regulations, consent orders, etc. that comprise its SIP.

The rationale for EPA's proposed action is explained in the NPRM and will not be restated here. EPA received no public comments on its NPRM.

II. Final Action

EPA is approving most of the elements of the infrastructure SIP submitted by Massachusetts on February 9, 2018, for the 2012 PM_2.5, including the interstate transport requirements at CAA § 110(a)(2)(D)(i)(I). This submittal also addresses the interstate transport requirements for the 2006 PM_2.5 NAAQS, which we are likewise approving. In addition, EPA is approving a SIP revision submitted by Massachusetts on January 31, 2008, addressing the interstate transport requirements for the 1997 PM_2.5 NAAQS.

EPA's action for each element for the 2012 PM_2.5 NAAQS is stated in Table 1 below.

In the above table, the key is as follows:

We are converting to full approval previous conditional approvals for elements A and E(ii) for the 1997 and 2006 PM_2.5 NAAQS and previous conditional approvals for element A for the 1997 ozone, 2008 lead, 2008 ozone, 2010 nitrogen dioxide, and 2010 sulfur dioxide NAAQS. For the 1997 and 2006 PM_2.5 NAAQS, we are also approving prong 4 of section 110(a)(2)(D)(i)(II) and the section 115-related (international pollution abatement) requirements of section 110(a)(2)(D)(ii).

We are issuing a finding of failure to submit for the PSD-related requirements of (C)2, (D)2, (D)4, (J)1, and (J)3. Massachusetts, however, is already subject to a Federal Implementation Plan (FIP) for PSD, and so EPA will have no additional FIP obligations under section 110(c) of the Act once this action is finalized as proposed. Furthermore, this action will not subject the Commonwealth to mandatory sanctions.

EPA is also approving, and incorporating into the Massachusetts SIP, definitions of National Ambient Air Quality Standards (NAAQS) or Federal Ambient Air Quality Standards, PM₁₀or Particulate Matter 10, PM₁₀Emissions, PM_2.5or Particulate Matter 2.5, and PM_2.5Emissions in 310 CMR 7.00 that Massachusetts included in a submittal to EPA dated May 14, 2018.

EPA is also approving, and incorporating into the Massachusetts SIP, Massachusetts Executive Order 145, Consultation with Cities & Towns on Administrative Mandates, effective November 20, 1978, which Massachusetts included for approval in its infrastructure SIP submittal for the 2012 PM_2.5 NAAQS.

Finally, on March 4, 2019, EPA finalized a rule converting the conditional approval at 40 CFR 52.1119(a)(5) to full approval but inadvertently neglected to remove § 52.1119(a)(5) from the CFR. See 84 FR 7299; see also 40 CFR 52.1120. In today's action we are remedying that ministerial oversight by removing and reserving § 52.1119(a)(5).

III. Incorporation by Reference

In this rule, the EPA is finalizing regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, the EPA is finalizing the incorporation by reference Executive Order 145 and the part of 310 CMR 7.00 described in the amendments to 40 CFR part 52 set forth below. The EPA has made, and will continue to make, these documents generally available through https://www.regulations.gov and at the EPA Region 1 Office (please contact the person identified in the FOR FURTHER INFORMATION CONTACT section of this preamble for more information). Therefore, these materials have been approved by EPA for inclusion in the State implementation plan, have been incorporated by reference by EPA into that plan, are fully federally enforceable under sections 110 and 113 of the CAA as of the effective date of the final rulemaking of EPA's approval, and will be incorporated by reference in the next update to the SIP compilation.³

IV. Statutory and Executive Order Reviews

Under the Clean Air Act, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the Clean Air Act. Accordingly, this action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this action:

• Is not a significant regulatory action subject to review by the Office of Management and Budget under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
• This action is not an Executive Order 13771 regulatory action because this action is not significant under Executive Order 12866;
• Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
• Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.);
• Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4);
• Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);
• Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
• Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);
• Is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the Clean Air Act; and
• Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).

In addition, the SIP is not approved to apply on any Indian reservation land or in any other area where EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the rule does not have tribal implications and will not impose substantial direct costs on tribal governments or preempt tribal law as specified by Executive Order 13175 (65 FR 67249, November 9, 2000).

The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this action and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. This action is not a “major rule” as defined by 5 U.S.C. 804(2).

Under section 307(b)(1) of the Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by August 23, 2019. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)
