(ii) Crude oil. An activity constitutes processing of crude oil if it is performed to separate produced fluids by passing crude oil through mechanical separators to remove gas, placing crude oil in settling tanks to recover basic sediment and water, dehydrating crude oil, and operating heater-treaters that separate raw oil well effluent into crude oil, natural gas, and salt water.
(iii) Ores and minerals other than natural gas or crude oil. An activity constitutes processing of ores and minerals other than natural gas or crude oil if it meets the definition of mining processes under §1.613-4(f)(1)(ii), without regard to §1.613-4(f)(2)(iv).
(iv) Timber. An activity constitutes processing of timber if it is performed to modify the physical form of timber, including by the application of heat or pressure to timber, without adding any foreign substances. Processing of timber does not include activities that add chemicals or other foreign substances to timber to manipulate its physical or chemical properties, such as using a digester to produce pulp. Products that result from timber processing include wood chips, sawdust, rough lumber, kiln-dried lumber, veneers, wood pellets, wood bark, and rough poles. Products that are not the result of timber processing include pulp, paper, paper products, treated lumber, oriented strand board/plywood, and treated poles.

(2) Products that are obtained from third parties or produced onsite for use in the refinery, such as hydrogen, if excess amounts are sold.
(3) Any product that results from further chemical change of a product listed in paragraph (c)(6)(i)(A) of this section that does not result in the same or another product listed in paragraph (c)(6)(i)(A) of this section (for example, production of petroleum coke from heavy (refinery) residuum qualifies, but any upgrading of petroleum coke (such as to calcined coke) does not qualify because it is further chemically changed and does not result in the same or another product listed in paragraph (c)(6)(i)(A) of this section).
(4) Plastics or similar petroleum derivatives.
(ii) Ores and minerals other than natural gas or crude oil.
(A) An activity constitutes refining of ores and minerals other than natural gas or crude oil if it is one of the various processes performed subsequent to mining processes (as defined in paragraph (c)(5)(iii) of this section) to eliminate impurities or foreign matter and which are necessary steps in achieving a high degree of purity from metallic ores and minerals which are not customarily sold in the form of the crude mineral product, as specified in paragraph (c)(6)(ii)(B) of this section. Refining processes include: fine pulverization, electrowinning, electrolytic deposition, roasting, thermal or electric smelting, or substantially equivalent processes or combinations of processes used to separate or extract the specified metals listed in paragraph (c)(6)(ii)(B) of this section from the ore for the primary purpose of producing a purer form of the metal, as for example the smelting of concentrates to produce Doré bars or refining of blister copper.
(B) For purposes of this section, the specified metallic ores or minerals which are not customarily sold in the form of the crude mineral product are—
(1) Lead;
(2) Zinc;
(3) Copper;
(4) Gold;
(5) Silver; and
(6) Any other ores or minerals that the Commissioner may identify through published guidance.
(C) Refining does not include the introduction of additives that remain in the metal, for example, in the manufacture of alloys of gold. Also, the application of nonmining processes as defined in §1.613-4(g) in order to produce a specified metal that is considered a waste or by-product of production from a non-specified mineral deposit is not considered refining for purposes of this section.
(7) Transportation—(i) General rule. An activity constitutes transportation if it is performed to move minerals or natural resources, and products under paragraph (c)(4), (5), or (6) of this section, including by pipeline, marine vessel, rail, or truck. Except as provided in paragraph (c)(7)(ii) of this section, transportation does not include the movement of minerals or natural resources, and products produced under paragraph (c)(4), (5), or (6) of this section, directly to retail customers or to a place that sells or dispenses to retail customers. Retail customers do not include a person who acquires oil or gas for refining or processing, or a utility. Transportation includes the following activities:
(A) Providing storage services.
(B) Providing terminalling services, including the following: Receiving products from pipelines, marine vessels, railcars, or trucks; storing products; loading products to pipelines, marine vessels, railcars, or trucks for distribution; testing and treating, as well as blending and additization, if income from such activities would be qualifying income pursuant to paragraph (c)(10)(iv) and (v) of this section; and separating and selling excess renewable identification numbers acquired as part of additization services to comply with environmental regulations.
(C) Moving or carrying (whether by owner or operator) products via pipelines, gathering systems, and custody transfer stations.
(D) Operating marine vessels (including time charters), railcars, or trucks.

(ii) Transportation to retail customers or to a place that sells to retail customers. Transportation includes the movement of minerals or natural resources, and products under paragraph (c)(4), (5), or (6) of this section, via pipeline to a place that sells to retail customers. Transportation also includes the movement of liquefied petroleum gas via trucks, rail cars, or pipeline to a place that sells to retail customers or directly to retail customers.
(8) Marketing—(i) General rule. An activity constitutes marketing if it is the bulk sale of minerals or natural resources, and products under paragraph (c)(4), (5), or (6) of this section. Except as provided in paragraph (c)(8)(ii) of this section, marketing does not include retail sales (sales made in small quantities directly to end users), which includes the operation of gasoline service stations, home heating oil delivery services, and local natural gas delivery services.
(ii) Retail sales of liquefied petroleum gas. Retail sales of liquefied petroleum gas are included in marketing.
(iii) Certain activities that facilitate sale. Marketing also includes certain activities that facilitate sales that constitute marketing under paragraphs (c)(8)(i) and (ii) of this section, including packaging, as well as blending and additization, if income from blending and additization would be qualifying income pursuant to paragraph (c)(10)(iv) and (v) of this section.
(9) Fertilizer. [Reserved]
(10) Additional activities. The following types of income as described in paragraph (c)(10)(i) through (v) of this section will be considered derived from a section 7704(d)(1)(E) activity.
(i) Cost reimbursements. If the partnership is in the trade or business of performing a section 7704(d)(1)(E) activity, qualifying income includes income received to reimburse the partnership for its costs in performing that section 7704(d)(1)(E) activity, whether imbedded in the rate the partnership charges or separately itemized. Reimbursable costs may include the cost of designing, constructing, installing, inspecting, maintaining, metering, monitoring, or relocating an asset used in that section 7704(d)(1)(E) activity, or providing office functions necessary to the operation of that section 7704(d)(1)(E) activity (such as staffing, purchasing supplies, billing, accounting, and financial reporting). For example, a pipeline operator that charges a customer for its cost to build, repair, or schedule flow on the pipelines that it operates will have qualifying income from such activity whether or not it itemizes those costs when it bills the customer.
(ii) Hedging. [Reserved]
(iii) Passive Interests. Qualifying income includes income and gains from a passive interest or non-operating interest, including production royalties, minimum annual royalties, net profits interests, delay rentals, and lease-bonus payments, if the interest is in a mineral or natural resource as defined in paragraph (b) of this section. Payments received on a production payment will not be qualifying income if they are properly treated as loan payments under section 636.
(iv) Blending. Qualifying income includes income and gains from performing blending activities or services with respect to products under paragraph (c)(4), (5), or (6) of this section, so long as the products being blended are component parts of the same mineral or natural resource. For purposes of this paragraph (c)(10)(iv), products of oil and natural gas will be considered as from the same natural resource. Blending does not include combining different minerals or natural resources or products thereof together. However, see paragraph (c)(10)(v) of this section for rules concerning additization.
(v) Additization. Qualifying income includes income and gains from providing additization services with respect to products under paragraph (c)(4), (5), or (6) of this section to the extent specifically permitted in this paragraph (c)(10)(v). The addition of additives described in paragraph (c)(10)(v)(A) through (C) of this section is permissible if the additives aid in the transportation of a product, enhance or protect the intrinsic properties of a product, or are necessary as required by federal, state, or local law (for example, to meet environmental standards), but only if such additives do not create a new product.
(A) The addition of additives to products of natural gas and crude oil is permissible, provided that such additives constitute less than 5 percent (except that ethanol or biodiesel may be up to 20 percent) of the total volume for products of natural gas and crude oil and are added into the product by the terminal operator or upstream of the terminal operator.
(B) In the case of ores and minerals other than natural gas or crude oil, the addition of incidental amounts of material such as paper dots to identify shipments, anti-freeze to aid in shipping, or compounds to allay dust as required by law or reduce losses during shipping is permissible.
(C) In the case of timber, additization of incidental amounts to comply with government regulations is permissible, to the extent such additization does not create a new product. For example, the pressure treatment of wood is impermissible because it creates a new product.
(d) Intrinsic activities—(1) General requirements. An activity is an intrinsic activity only if the activity is specialized to support a section 7704(d)(1)(E) activity, is essential to the completion of the section 7704(d)(1)(E) activity, and requires the provision of significant services to support the section 7704(d)(1)(E) activity. Whether an activity is an intrinsic activity is determined on an activity-by-activity basis.
(2) Specialization. An activity is a specialized activity if—
(i) The partnership provides personnel (including employees of the partnership, an affiliate, subcontractor, or independent contractor performing work on behalf of the partnership) to support a section 7704(d)(1)(E) activity and those personnel have received training in order to support the section 7704(d)(1)(E) activity that is unique to the mineral or natural resource industry and of limited utility other than to perform or support a section 7704(d)(1)(E) activity; and
(ii) To the extent that the activity involves the sale, provision, or use of specific property, either—
(A) The property is primarily tangible property that is dedicated to, and has limited utility outside of, section 7704(d)(1)(E) activities and is not easily converted (as determined based on all the facts and circumstances, including the cost to convert the property) to another use other than supporting or performing the section 7704(d)(1)(E) activities (except that the use of non-specialized property typically used incidentally in operating a business will not cause a partnership to fail this paragraph (d)(2)(ii)(A)); or
(B) If the property is used as an injectant to perform a section 7704(d)(1)(E) activity that is also commonly used outside of section 7704(d)(1)(E) activities (such as water and lubricants), the partnership provides the injectants exclusively to those engaged in section 7704(d)(1)(E) activities; the partnership is also in the trade or business of collecting, cleaning, recycling, or otherwise disposing of injectants after use in accordance with Federal, state, or local regulations concerning waste products from mining or production activities; and the partnership operates its injectant delivery and disposal services within the same geographic area.
(3) Essential.
(i) An activity is essential to the section 7704(d)(1)(E) activity if it is required to—
(A) Physically complete a section 7704(d)(1)(E) activity (including in a cost-effective manner, such as by making the activity economically viable), or
(B) Comply with Federal, state, or local law regulating the section 7704(d)(1)(E) activity.
(ii) Legal, financial, consulting, accounting, insurance, and other similar services do not qualify as essential to a section 7704(d)(1)(E) activity.
(4) Significant services.
(i) An activity requires significant services to support the section 7704(d)(1)(E) activity if those services must be conducted on an ongoing or frequent basis by the partnership's personnel at the site or sites of the section 7704(d)(1)(E) activities. Alternatively, those services may be conducted offsite if the services are performed on an ongoing or frequent basis and are offered to those engaged in one or more section 7704(d)(1)(E) activities. If the services are monitoring, those services must be offered exclusively to those engaged in one or more section 7704(d)(1)(E) activities. Whether services are conducted on an ongoing or frequent basis is determined based on all the facts and circumstances, including recognized best practices in the relevant industry.
(ii) Personnel perform significant services only if those services are necessary for the partnership to perform an activity that is essential to the section 7704(d)(1)(E) activity, or to support the section 7704(d)(1)(E) activity. Personnel include employees of the partnership, an affiliate, subcontractor, or independent contractor performing work on behalf of the partnership.
(iii) Services are not significant services with respect to a section 7704(d)(1)(E) activity if the services principally involve the design, construction, manufacturing, repair, maintenance, lease, rent, or temporary provision of property.
(e) Interpretations of section 611 and section 613. This section and interpretations of this section have no effect on interpretations of sections 611 and 613, or other sections of the Code, or the regulations thereunder; however, this section incorporates some of the interpretations under section 611 and 613 and the regulations thereunder as provided in this section.
(f) Examples. The following examples illustrate the provisions of this section:
(ii) Ethylene and propylene are products of refining as provided in paragraph (c)(6)(i) of this section; therefore, Z is engaged in a section 7704(d)(1)(E) activity. The income Z receives from the sale of ethylene and propylene is qualifying income for purposes of section 7704(d)(1)(E).
(ii) Y's activities give rise to products of refining as provided in paragraph (c)(6)(i) of this section; therefore, Y is engaged in a section 7704(d)(1)(E) activity. The income Y receives from the sales of ethylene is qualifying income for purposes of section 7704(d)(1)(E).
(ii) With respect to the production of gasoline or diesel from methane, gasoline and diesel are products of refining as provided in paragraph (c)(6)(i) of this section; therefore, Y is engaged in a section 7704(d)(1)(E) activity. Y's income from the sale of gasoline and diesel is qualifying income for purposes of section 7704(d)(1)(E).
(iii) The income from the sale of methanol, an intermediate product in the conversion process, is not qualifying income for purposes of section 7704(d)(1)(E) because methanol is not a product of processing or refining as defined in paragraph (c)(5) and (6) of this section.
(ii) The chemical conversion of methanol and synthesis gas into gasoline and diesel is not refining as provided in paragraph (c)(6)(i) of this section because it is not the physical or chemical conversion or the separation or blending of products listed in paragraph (c)(6)(i)(A) of this section. Accordingly, the income from the sales of the gasoline and diesel is not qualifying income for purposes of section 7704(d)(1)(E).
(ii) X's sale of a refined product to the government entity is a section 7704(d)(1)(E) activity because it is a bulk transportation and sale as described in paragraph (c)(7) and (8) of this section and is not a retail sale.
(ii) X, as an operator of pipelines, is engaged in transportation pursuant to paragraph (c)(7)(i)(C) of this section. The reimbursement X receives from A for X's cost to build the pipeline is qualifying income pursuant to paragraph (c)(10)(i) of this section because X receives the income to reimburse X for its costs in performing X's transportation activity and reimbursable costs may include construction costs. In contrast, Y is not in the trade or business of performing a 7704(d)(1)(E) activity, thus income Y received from X for building the pipeline is not qualifying income to Y.
(ii) X's income from transporting natural gas in its interstate and intrastate pipelines is qualifying income for purposes of section 7704(c) because transportation of natural gas is a section 7704(d)(1)(E) activity as provided in paragraph (c)(7)(i)(C) of this section.
(iii) The income X obtains from its water delivery services is not a section 7704(d)(1)(E) activity as provided in paragraph (c) of this section. However, because X's water delivery supports A's development of natural gas, a section 7704(d)(1)(E) activity, X's income from water delivery services may be qualifying income for purposes of section 7704(c) if the water delivery service is an intrinsic activity as provided in paragraph (d) of this section. An activity is an intrinsic activity if the activity is specialized to support the section 7704(d)(1)(E) activity, is essential to the completion of the section 7704(d)(1)(E) activity, and requires the provision of significant services to support the section 7704(d)(1)(E) activity. Under paragraph (d)(2)(ii)(B) of this section, the provision of water for use as an injectant in a section 7704(d)(1)(E) activity is specialized to that activity only if the partnership (1) provides the water exclusively to those engaged in section 7704(d)(1)(E) activities, (2) is also in the trade or business of cleaning, recycling, or otherwise disposing of water after use in accordance with Federal, state, or local regulations concerning waste products from mining or production activities, and (3) operates these disposal services within the same geographic area as that in which it delivers water. Because X does not perform such disposal services, X's water delivery activities are not specialized to support the section 7704(d)(1)(E) activity. Thus, X's water delivery is not an intrinsic activity. Accordingly, X's income from the delivery of water is not qualifying income for purposes of section 7704(c).
(ii) The income X obtains from its water delivery services is not a section 7704(d)(1)(E) activity as provided in paragraph (c) of this section. However, because X's water delivery supports A's development of natural gas, a section 7704(d)(1)(E) activity, X's income from water delivery services may be qualifying income for purposes of section 7704(c) if the water delivery service is an intrinsic activity as provided in paragraph (d) of this section.
(iii) An activity is an intrinsic activity if the activity is specialized to support the section 7704(d)(1)(E) activity, is essential to the completion of the section 7704(d)(1)(E) activity, and requires the provision of significant services to support the section 7704(d)(1)(E) activity. Under paragraph (d)(2)(ii)(B) of this section, the provision of water for use as an injectant in a section 7704(d)(1)(E) activity is specialized to that activity only if the partnership (1) provides the water exclusively to those engaged in section 7704(d)(1)(E) activities, (2) is also in the trade or business of cleaning, recycling, or otherwise disposing of water after use in accordance with Federal, state, or local regulations concerning waste products from mining or production activities, and (3) operates these disposal services within the same geographical area as where it delivers water. X's provision of personnel is specialized because those personnel received training regarding the recovery and recycling of flowback produced during the development of natural gas, and this training is of limited utility other than to perform or support the development of natural gas. The provision of water is also specialized because water is an injectant used to perform a section 7704(d)(1)(E) activity, and X also collects and treats flowback in accordance with state regulations as part of its water delivery services. Therefore, X meets the specialization requirement. The delivery of water is essential to support A's development activity because the water is needed for use in fracturing to develop A's natural gas reserve in a cost-efficient manner. Finally, the water delivery and recovery and recycling activities require significant services to support the development activity because X's personnel provide services necessary for the partnership to perform the support activity at the development site on an ongoing or frequent basis that is consistent with best industry practices. Because X's delivery of water and X's collection, transport, and treatment of flowback is a specialized activity, is essential to the completion of a section 7704(d)(1)(E) activity, and requires significant services, the delivery of water and the transport and treatment of flowback is an intrinsic activity. X's income from the delivery of water and the collection, treatment, and transport of flowback is qualifying income for purposes of section 7704(c).
(g) Effective/applicability date and transition rule.
(1) In general. Except as provided in paragraph (g)(2) of this section, this section applies to income earned by a partnership in a taxable year beginning on or after January 19, 2017. Paragraph (g)(2) of this section applies during the period that ends on the last day of the partnership's taxable year that includes January 19, 2027 (Transition Period).
(2) Income during Transition Period. A partnership may treat income from an activity as qualifying income during the Transition Period if—
(i) The partnership received a private letter ruling from the IRS holding that the income from that activity is qualifying income;
(ii) Prior to May 6, 2015, the partnership was publicly traded, engaged in the activity, and treated the activity as giving rise to qualifying income under section 7704(d)(1)(E), and that income was qualifying income under the statute as reasonably interpreted prior to May 6, 2015;
(iii) Prior to May 6, 2015, the partnership was publicly traded and had entered into a binding agreement for construction of assets to be used in such activity that would give rise to income that was qualifying income under the statute as reasonably interpreted prior to May 6, 2015; or
(iv) The partnership is publicly traded and engages in the activity after May 6, 2015 but before January 19, 2017, and the income from that activity is qualifying income under the proposed regulations (REG-132634-14) contained in the Internal Revenue Bulletin (IRB) 2015-21 (see https://www.irs.gov/pub/irs-irbs/irb15-21.pdf).
(3) Relief from technical termination. In the event of a technical termination under section 708(b)(1)(B) of a partnership that satisfies the requirements of paragraph (g)(2) of this section without regard to the technical termination, the resulting partnership will be treated as the partnership that satisfies the requirements of paragraph (g)(2) of this section for purposes of applying the Transition Period.
