Clajon Gas Co., L.P., Aquila Gas Pipeline Corp., Tax Matters Partner, Petitioner v. Commissioner of Internal Revenue, Respondent, 119 T.C. 197

Halpern, Judge: By notices of final partnership administrative adjustment dated April 28, 1997, respondent made adjustments to partnership returns filed by Clajon Gas Co., L.P. (Clajon), for taxable years ending December 31, 1990, September 25, 1991, December 31, 1991, and June 30, 1992 (the audit years).

Taking into account issues and items resolved by the parties, the sole adjustments in dispute are respondent’s adjustments reducing Clajon’s deduction for “pipeline depreciation”, as follows: TYE Adjustment 12/31/90 . $7,920,799 9/25/91 . 19,644,092 12/31/91 . 4,372,916 6/30/92 . 12,187,347 The issue for our decision is the proper cost recovery period to be used by Clajon in determining its depreciation deductions for the property in question. Unless otherwise indicated, all

section references are to the Internal Revenue Code in effect for the years at issue, and all Rule references are to the Tax Court Rules of Practice and Procedure. Petitioner bears the burden of proof. Rule 142(a). FINDINGS OF FACT Some facts are stipulated and are so found. The stipulation of facts, with accompanying exhibits, is incorporated herein by this reference. Principal Place of Business At the time the petition was filed, Clajon’s principal place of business was in San Antonio, Texas. Natural Gas Production Process Natural gas is extracted from the earth through gas wells.

It leaves the earth at the wellhead and passes into flow lines. The flow lines carry the gas to a separator located at the well site or to a central production facility (which serves two or more wells), where, among other things, oil, water, and sand are removed from the gas. The gas next flows to a meter installation for measurement and then enters a gathering system.

A gathering system is a system of interconnected subterranean pipelines and related facilities, including compression stations and metering installations, that aggregates gas from multiple wells for delivery to a transmission line or a gas processing plant. A gathering system’s smaller diameter pipelines, sometimes called feeder lines or lateral lines, connect individual wells or one or more central production facilities to larger diameter lateral lines or trunk lines that eventually deliver the gas to a gas processing plant or to a transmission line.

Gas containing substantial amounts of natural gas liquids (ngls), such as ethane, propane, butane, and natural gasoline (termed “wet gas”), must be fractionated to remove ngls before the gas can be transmitted to consumers. Fractionation occurs at gas processing plants, where the resulting components are residue gas (primarily methane) and extracted NGLs. The NGLs are delivered by truck, rail, or pipeline to another specialized processing plant for further fractionation and marketing. The residue gas is delivered to a transmission line.

The person extracting the gas from the earth may own the gathering system, or it may be owned by an independent pipeline company (i.e., a company not in the business of extracting gas from the earth). Clajon’s Gathering Systems During the audit years, Clajon’s activities included purchasing, transporting, processing, and selling natural gas and NGLs. Clajon owned six natural gas gathering systems, all located in Texas (the Texas gathering systems), and two natural gas processing plants, one in College Station, Texas (which was closed in early 1990), and one in La Grange, Texas.

The Texas gathering systems were known as the Southeast Texas Pipeline System, which gathered wet gas for delivery to the processing plants, and the Mentone Pipeline System, Gomez Pipeline System, Maverick County Pipeline System, Rhoda Walker Pipeline System, and Panola County Pipeline System, which gathered gas containing little or no ngls (termed “lean gas”) for delivery to purchasers’ transmission pipelines. The Panola and Rhoda Walker Systems provided compression and dehydration services. The Gomez and Mentone Systems provided dehydration services.

The Texas gathering systems included more than 1,100 miles of feeder, lateral, and trunk lines. Clajon, via the Texas gathering systems, purchased and transported gas from 190 third-party gas producers and more than 1,000 wells. Clajon did not own any oil or natural gas reserves and did not own an economic interest in any well connected to the Texas gathering systems. Clajon’s Contractual Relationships During the audit years, gas flowed through the Texas gathering systems under the following types of contracts: wellhead purchase contracts, gas processing contracts, and gas transportation contracts.

Under a wellhead purchase contract, Clajon purchases a producer’s gas at a meter located at the producer’s well. The price may be fixed, or it may be calculated based upon the price received by Clajon for residue gas at the tailgate of the gas processing plant. A gas processing contract is similar, except that Clajon and the producer share revenues from Clajon’s sale of extracted NGLs and residue gas. Under a gas transportation contract, Clajon charges its customers a fee to move gas through one of the Texas gathering systems.

Depreciation Adjustments in Dispute Respondent’s adjustments to “pipeline depreciation” consist of separate adjustments with respect to “pipelines”, “compressor stations” and “meter runs”. Clajon depreciated those assets using a 7-year recovery period. Respondent determined that Clajon should have used a 15-year recovery period. We shall generally refer to the foregoing elements of Clajon’s gathering system, collectively and without distinction, as gathering pipelines. OPINION I.

Introduction This case involves a dispute as to the length (in years) of the recovery period that Clajon must; use in calculating its annual depreciation deductions for the gathering pipelines. On similar facts, we decided in the Commissioner’s favor in Duke Energy Natural Gas Corp. v. Commissioner, 109 T.C. 416 (1997), revd. 172 F.3d 1255 (10th Cir. 1999). Petitioner urges us not to follow our decision in Duke Energy and to adopt the reasoning of the Court of Appeals for the Tenth Circuit in that case. Duke Energy Natural Gas Corp. v. Commissioner, 172 F.3d 1255 (10th Cir. 1999), revg. 109 T.C. 416 (1997).

As explained below, we follow our decision in Duke Energy, and we hold that the proper recovery period for the gathering pipelines is 15 years. II. Applicable Statutory and Administrative Provisions

Section 167(

a) allows “as a depreciation deduction a reasonable allowance for the exhaustion, wear and tear * * * of property used in * * * [a] trade or business”.

Section 167(

b) references

section 168 for determination of the depreciation deduction in the case of property to which

section 168 applies.

Section 168 is entitled “Accelerated Cost Recovery System”, and it sets forth a cost recovery system based not on the useful life of an item of property but, instead, on certain congressionally determined (accelerated) recovery periods. In pertinent part,

section 168(

a) provides: “the depreciation deduction provided by

section 167(

a) for any tangible property shall be determined by using * * * the applicable recovery period”. Pursuant to

section 168(

c) and (e), the recovery period for property is based upon (but, generally, is shorter than) its “class life”.

Section 168(i)(

l) defines “class life” as “the class life * * * which would be applicable with respect to any property as of January 1, 1986, under subsection (

m) of

section 167”.

Section 167(m)(l), in pertinent part, provided for depreciation “based on the class life prescribed by the Secretary which reasonably reflects the anticipated useful life of that class of property to the industry or other group.”

Section 167(m) (which was added to the Internal Revenue Code by

section 109 of the Revenue Act of 1971, Pub. L. 92-178, 85 Stat. 508) codified, with certain modifications, the Asset Depreciation Range (adr) system described in

section 1.167(a)-ll, Income Tax Regs., and, in particular, the regulations’ adoption of asset guideline classes and periods or “class lives”. See H. Rept. 92-533, at 31-34 (1971), 1972-1 C.B. 498, 514-516; S. Rept. 92-437, at 45-52 (1971), 1972-1 C.B. 559, 584-588. Consistent with the directive in

section 167(m)(

l) to prescribe class lives for depreciable assets,

section 1.167(a)-11(b)(4)(h), Income Tax Regs., provides that asset guideline classes and periods (lives) will be “established, supplemented, and revised * * *, and will be published in the Internal Revenue Bulletin.” The regulation references Rev. Proc. 72-10, 1972-1 C.B. 721, as setting forth the applicable “asset guideline classes”. Rev. Proc. 72-10, supra, was the first of several revenue procedures establishing asset guideline classes, each superseding or obsoleting its predecessor and culminating in Rev. Proc. 87-56, 1987-2 C.B. 674. Rev.

Proc. 87-56, supra, is the revenue procedure establishing asset guideline classes that is in effect for purposes of this case. The Rev. Proc. 87-56, supra, asset guideline classes at issue in this case are as follows: [Asset Class] 13.2 Exploration for and Production of Petroleum and Natural Gas Deposits: Includes assets used by petroleum and natural gas producers for drilling of wells and production of petroleum and natural gas, including gathering pipelines and related storage facilities.

Also includes petroleum and natural gas offshore transportation facilities used by producers and others consisting of platforms (other than drilling platforms classified in Class 13.0), compression or pumping equipment, and gathering and transmission lines to the first onshore transshipment fácility. * * * [Asset Class] 46.0 Pipeline Transportation: Includes assets used in the private, commercial, and contract carrying of petroleum, gas and other products by means of pipes and conveyors.

The trunk lines and related storage facilities of integrated petroleum and natural gas producers are included in this class. * * * [Rev. Proc. 87-56, 1987-2 C.B. at 678, 684.] Property within asset class 13.2 (13.2) is assigned a class life of 14 years and has a recovery period of 7 years; property within asset class 46.0 (46.0) is assigned a class life of 22 years and has a recovéry period of 15 years. Id. III. Class Lives Are Composite Lives Historical material pertaining to the ADR system establishes that the class lives contemplated in

section 1.167(a)-ll(b)(4)(ii), Income Tax Regs., and established by Rev. Proc. 87-56, supra, and preceding revenue procedures, are composite lives. In other words, each class life is based on the useful lives of the assets constituting the class but does not necessarily equal the useful life of any constituent asset. In June 1971, contemporaneous with the adoption of

section 1.167(a)-ll, Income Tax Regs., by T.D. 7128, 1971-2 C.B. 132, the Department of the Treasury published “Asset Depreciation Range (adr) System” (U.S. Government Printing Office: 1971 0-428-904) (hereafter referred to as Treasury Publication or T.P.). The Treasury Publication states that, in 1962, with the publication of Rev. Proc. 62-21, 1962-2 C.B. 418, the Treasury introduced a fundamental change in the concept of depreciation. T.P. at 212-213. The fundamental change was to classify assets on a basis other than the particular life of the particular asset to the particular user. Id. at 215.

On the new basis, assets were classified “as a stock of capital even though assets within a class were heterogeneous with respect to ages, useful lives, and physical characteristics.” Id. “Assets within the class would have individual lives far longer and far shorter than the guideline class life.” Id. at 215-216. The Treasury Publication describes Rev. Proc. 62-21, supra, as providing a substitute for the thousands of asset classifications of the previous system. Id. at 212-213. Under Rev.

Proc. 62-21, supra, “assets were grouped by broad industrial classifications and by certain broad general asset classifications, with a ‘guideline life’ established for each of these classes.” Id. at 213. An examination of the asset guideline classes in Rev. Proc. 62-21, supra, discloses that, generally, the classes are tied to particular business activities. The drafters of the revenue procedure recognized that the anticipated useful life of many assets, even the same types of assets, will vary in accordance with the experience of persons using such assets.

The drafters assumed that persons in the same business activity would have similar experiences and, except for assets used by businesses generally (e.g., trucks and railroad cars), generally classified assets by business activity. The Treasury Publication describes the ADR and class life system then being established by Treasury decision (T.D. 7128, 1971-2 C.B. 132, adopting

section 1.167(a)-ll, Income Tax Regs.) as, essentially, an extension and modification of the asset guideline class approach taken in Rev. Proc. 62-21, supra. T.P. 212-219. The Treasury Publication describes adoption of the new system as being prompted, in part, by (1) recognition that it had been more than 7 years since there had been any significant changes in the guidelines classes or lives, and (2) requests from members of Congress that Treasury study the adequacy of the then-existing depreciation allowances. Id. at 215, 217-218. Reflecting the approach that had been taken in Rev. Proc. 62-21, supra, and

section 1.167-11, Income Tax Regs., Congress, in

section 167(m)(l), provided that, for each class of property, the Secretary must prescribe a class life that reflects the anticipated useful life of that class of property “to the industry or other group.” Pursuant to that mandate, the Secretary had the authority to, and did, subdivide industries, establishing asset guideline classes inclusive of one or more sectors of the industry and exclusive of others. Thus, the same asset used in more than one sector of an industry might be included in two or more asset guideline classes, each with its own (different) class life.

Gathering pipelines are subject to depreciation by both natural gas producers (under 13.2) and pipeline companies (under 46.0). IV. Duke Energy In Duke Energy Natural Gas Corp. v.

Commissioner, 109 T.C. at 421, we concluded that the taxpayer’s gathering systems were “used primarily by a pipeline company [the taxpayer] to carry gas to a production facility, which * * * brings them within asset class 46.0.” In reaching that conclusion, we rejected the taxpayer’s jargument “that its gathering systems are included in asset class 13.2 because the systems are used by petroleum and natural gas producers to produce natural gas in that the systems are essential to the production and sale of gas in the market.” Id.

We noted: “The mere fact that the gathering systems may have helped producers produce and sell their gas in the market does not mean that the systems are exploration or production assets within * * * asset class 13.2.” Id. In reversing our decision in Duke Energy, the Court of Appeals for the Tenth Circuit reasoned that “the plain language of Asset Class 13.2 leads most logically to a reading that includes Duke’s gathering systems even though they are ‘used by’ producers through contractual arrangements with Duke.” Duke Energy Natural Gas Corp. v. Commissioner, 172 F.3d at 1259.

The Court of Appeals stated that “Duke’s gathering systems are literally used by producers for gas production in a number of different ways”, id. at 1258, noting the parties’ agreement that “producers would not be able to produce natural gas in the absence of an adequately designed gathering system”, id. After reviewing the overall function and usage of gathering systems, the Court of Appeals stated that “the economic character of Duke’s gathering activities is more akin to production than pipeline operation.” Id. at 1259.

The Court of Appeals rejected the Government’s argument that the words “used by” in 13.2 incorporate an ownership requirement, reasoning: “‘Use’ does not mean ‘own’ in either the legal dictionary definition of the word use * * * nor in everyday parlance.” Id. Ultimately, the Court concluded as follows: Because of the primary use of gathering systems in the process of producing natural gas, as well as the plain language of the asset class descriptions, Duke’s gathering systems fit more logically within Asset Class 13.2 than Asset Class 46.0. [Id. at 1262; fn. ref. omitted.] V. Nonapplication of Golsen v.

Commissioner Under the rule of Golsen v. Commissioner, 54 T.C. 742, 757 (1970), affd. 445 F.2d 985 (10th Cir. 1971), this Court will “follow a Court of Appeals decision which is squarely in point where appeal from our decision lies to that Court of Appeals”. At the time the petition was filed, Clajon’s principal place of business was San Antonio, Texas. Pursuant to

section 7482(b)(1)(E), an appeal from our decision in this case would likely lie to the Court of Appeals for the Fifth Circuit, where there is no authority on point. We are, therefore, not required by Golsen to follow the Court of Appeals for the Tenth Circuit’s decision in Duke Energy Natural Gas Corp. v. Commissioner, supra. VI. The Gathering Pipelines Fall Within 46.0 Rather Than 13.2 Because Clajon Was Not a “Producer”, and It Is Clajon’s Use That Is Relevant A. Analysis 1.

Clajon Was Not a “Producer” of Natural Gas In order for the gathering pipelines to be included in 13.2, it is necessary that they be “used by” a natural gas “producer” for “production of” natural gas. There is, thus, both an “actor” requirement (used by) and an “activity” requirement (the production of natural gas) necessary for 13.2 classification. The actor requirement is satisfied if the gathering pipelines are used by a natural gas “producer”. Duke Energy conceded that it was “not a producer of gas as that term is used in the asset class descriptions of MACRS.” Duke Energy Natural Gas Corp. v.

Commissioner, 172 F.3d at 1256 n.2 (apparently referring to the asset guideline classes set forth in Rev. Proc. 87-56, supra). Although petitioner has not specifically conceded (nor has it been stipulated) that Clajon is not a producer of natural gas, counsel for petitioner tacitly admitted as much during the trial and, again, during the posttrial oral argument. Similarly, petitioner’s expert witness acknowledged that a gas gatherer is not a producer of natural gas. Therefore, we find that Clajon was not a producer as that term is commonly used in the natural gas industry.

Authorities in the oil and gas field agree. See Williams & Meyers, Manual of Oil and Gas Terms 846 (11th ed. 2000), generally defining a producer as “[a]n operator who owns wells that produce * * * gas.” 2. The Relevant “Use” Under 13.2 and 46.0 Is That of the Taxpayer, Clajon a. Introduction In Duke Energy Natural Gas Corp. v. Commissioner, supra, the Court of Appeals focused upon industry (rather than taxpayer) usage of Duke Energy’s gathering system.

It concluded: “Within the industry and in the functional and contractual relationship between producers and nonproducer gathering system owners, Duke’s gathering systems are literally used by producers for gas production”. Id. at 1258. This focus fails to take into account, and is contrary to, an important aspect of the regulations authorizing the issuance of Rev. Proc. 87-56, 1987-2 C.B. 674, and its predecessor revenue procedures.

The regulations require not only that property be classified by the type of activity in which the property is used but also that the taxpayer depreciating property on the basis of a particular class life must itself be engaged in (be the actor in) the activity described in the asset guideline class. Moreover, the Court of Appeals’ focus fails to take into account the segmented approach to the natural gas industry taken in Rev. Proc. 87-56, supra. b. The Regulations

Section 1.167(a)-ll(b)(4)(iii)(6), Income Tax Regs., states that “property shall be included in the asset guideline class for the activity in which the property is primarily used” and that “[property shall be classified according to primary use even though the activity in which such property is primarily used is insubstantial in relation to all the taxpayer’s activities.” (Emphasis added.) Because the regulation considers the substantiality of the primary use activity in relation to all of the taxpayer’s activities, we interpret the regulation as comparing a part to the whole (i.e., one of the taxpayer’s activities is compared to all of the taxpayer’s activities) so that it is the taxpayer’s primary use of the property that is relevant.

It is, thus, the taxpayer’s primary use of the property, and not some other person’s use, that determines classification. The taxpayer in question, of course, is the person electing to use asset guideline classes for purposes of computing its depreciation deductions for property placed in service during the year. That it is only the electing taxpayer’s use that counts is verified by the special rule in the regulations that applies to leased property. After stating the general rule that “property shall be included in the asset guideline class for the activity in which the property is primarily used”,

section 1.167(a) — ll(b)(4)(iii)(6), Income Tax Regs., cross-references paragraph (e)(3)(iii) “for [the] rule for leased property”. The referenced paragraph provides: “In the case of a lessor of property [claiming an allowance for depreciation of leased property], unless there is an asset guideline class in effect for lessors of such property, the asset guideline class for such property shall be determined as if the property were owned by the lessee” (Emphasis added.) That provision would be wholly unnecessary under the “industry usage” rationale of the Court of Appeals in Duke Energy Natural Gas Corp. v.

Commissioner, 172 F.3d 1255 (10th Cir. 1999). Moreover, the regulation drafter’s analogy to deemed ownership by the lessee strengthens the presumption that, in general (outside the special case for leased property), it is the taxpayer-owner’s use of property that determines its proper classification. It is true that, in the case of the activity-based classifications, Rev. Proc. 87-56, supra, does not specifically state that only the taxpayer’s activities are relevant. We conclude, however, that, because such limitation is contained in the regulations pursuant to which Rev.

Proc. 87-56, supra, was issued, it is implicit in all activity-based classifications, including 13.2 and 46.0. We must, therefore, look to such classifications to see which describes petitioner’s activities. c. Rev. Proc. 87 — 56

(1) Intraindustry Asset Classes The focus of the Court of Appeals on industry usage of gathering pipelines also ignores the fact that Rev. Proc. 87-56, 1987-2 C.B. 674, does not provide one asset guideline class for the whole “gas industry”.

Rather, several classifications apply to the industry, each designed to encompass a segment of the industry, including “Offshore Drilling” (13.0), “Drilling of Oil and Gas Wells” (13.1), “Exploration for and Production of Petroleum and Natural Gas Deposits” (13.2), “Pipeline Transportation” (46.0), “Natural Gas Production Plant,” (49.23), “Gas Utility Trunk Pipelines and Related Storage Facilities” (49.24), and “Liquefied Natural Gas Plant” (49.25). That segmented approach to the oil and gas industry is entirely consistent with the statutory scheme. Under former

section 167(m)(l), the depreciation allowance for property included in any asset guideline class had to be based upon the “class life prescribed by the Secretary which reasonably reflects the anticipated useful life of that class of property to the industry or other group” (Emphasis added.) Such an approach is also consistent with Treasury’s description of

section 1.167(a)-ll, Income Tax Regs., as, essentially, an extension of the composite class life system adopted in Rev. Proc. 62-21, 1962-2 C.B. 418. See supra sec. III.

(2) Asset Class 13.2 Asset guideline class 13.2 describes property, including gathering pipelines, used by natural gas producers. Since, however, we have found that petitioner is not a natural gas producer, its gathering pipelines are not 13.2 property. Given the composite nature of class lives, that is an appropriate result. If a taxpayer is not engaged in the activity described in an asset guideline class, then the associated class life is not representative of the life of any class of business assets owned by him. Only by coincidence would the class life be the useful life of any asset owned by the taxpayer.

To permit such a taxpayer to depreciate a particular asset or type of asset on the basis of a composite class life designed for a completely different group of taxpayers utilizing a completely different mix of assets would be to frustrate the overall intent and design of the class life system adopted by Congress and implemented by the regulations and by Rev. Proc. 87-56, supra. Petitioner is not a gas producer and, therefore, has no claim on 13.2. The point is aptly illustrated by the treatment of drilling equipment under Rev. Proc. 87-56, supra.

Asset class 13.1 (13.1), entitled “Drilling of Oil and Gas Wells”, provides a 6-year class life and 5-year recovery period for “assets used in the drilling of onshore oil and gas wells”, e.g., an oil or gas drilling rig. The same assets “used by petroleum and natural gas producers” fall within 13.2, which, as noted above, provides a 14-year class life and 7-year recovery period.

Just as a drilling rig may have two different class lives and recovery periods, depending upon the asset class within which it is includable, so too may gathering pipelines be subject to different class lives and recovery periods depending upon the user and the asset class appropriate to that user.

(3) Asset Class 46.0 Petitioner argues that 46.0 is intended to encompass only transmission pipelines. In support of its argument, petitioner states that, within the natural gas industry, “the term ‘transportation pipeline’ is synonymous with ‘transmission pipeline’”, and that the Federal Energy Regulatory Commission (ferc) distinguishes between gathering, over which it lacks jurisdiction, and the interstate transportation of natural gas, over which it has jurisdiction, a distinction upon which the Court of Appeals for the Tenth Circuit also relies. See Duke Energy Natural Gas Corp. v.

Commissioner, 172 F.3d at 1261-1262. We reject petitioner’s argument for several reasons. To begin with, 46.0, although entitled “Pipeline Transportation”, encompasses “assets used in the private, commercial, and contract carrying of * * * gas * * * by means of pipes”. (Emphasis added.) The alleged term of art, “transportation”, nowhere appears in the descriptive language of 46.0, and it is clear that Clajon’s primary use of its gathering pipelines is “in * * * carrying * * * gas”. Thus, the plain language of 46.0 supports the inclusion of Clajon’s gathering pipelines within that asset class.

Secondly, we do not agree with the conclusion of the Tenth Circuit Court of Appeals that FERC’s distinction between gathering and transmission lines necessarily establishes that FERC considers gathering systems as related to production. See Duke Energy Natural Gas Corp. v. Commissioner, 172 F.3d at 1262. In

section 1(

b) of the Natural Gas Act of 1938 (NGA), Pub. L. 688, 52 Stat. 821, currently codified at 15 U.S.C. sec. 717(b) (2000), it is provided that the NGA “shall apply to the transportation of natural gas in interstate commerce * * * but shall not apply to * * * the production or gathering of natural gas.” The quoted language indicates that Congress considered “gathering” to be separate and distinct from “production”. Indeed, had it considered “gathering” to be included within the term “production”, Congress would not have found it necessary to separately exclude both from Federal regulation.

Moreover, that FERC does not consider gathering and transportation (of gas) to be mutually exclusive terms is illustrated by another decision of the Court of Appeals for the Tenth Circuit, which involved the question of FERC jurisdiction over an interstate gathering system. See Northwest Pipeline Corp. v. FERC, 905 F.2d 1403 (10th Cir. 1990). In that case, FERC had asserted jurisdiction over the system on the basis that the primary function of the system was “the transportation of natural gas in interstate commerce.” Id. at 1405, 1410.

The Court of Appeals disagreed that transportation was the primary function of the system if transportation was only incidental to an exempt function of the system (i.e., gathering natural gas): “Some transportation must occur to move the gas from the wellhead in some manner. What the Commission must decide in applying the primary function test is whether that transportation is incidental to traditional gathering functions and, thus, exempt from its jurisdiction.” Id. at 1410-1411 (fn. ref. omitted).

It is clear, however, that both FERC and the court agreed that gathering pipelines are used to transport natural gas. Thirdly, although petitioner’s expert was of the opinion (and respondent’s principal expert did not disagree) that gathering pipelines have a shorter useful life than do transmission or distribution pipelines, that does not persuade us that the class life of 22 years assigned to 46.0 is inappropriate for gathering pipelines.

The class life of 22 years assigned to 46.0 is a composite life, and petitioner has made no showing that, on a composite basis, that life does not fairly balance the relatively short life of gathering pipelines against the relatively long lives of transmission or distribution pipelines. B. Conclusion Because Clajon is not a “producer” of natural gas, and because it is Clajon’s use of its gathering pipelines that is relevant under 13.2, such gathering pipelines were not “used by” a natural gas “producer” as required for inclusion within such asset guideline class.

Rather, Clajon’s gathering pipelines are includable within 46.0 since they are “assets used [by Clajon] in the * * * carrying of * * * gas * * * by means of pipes and conveyors.” VII. Conclusion Clajon is required to depreciate the gathering pipelines utilizing a 15-year recovery period. Decision will be entered under Rule 155. Reviewed by the Court. Cohen, Gerber, Ruwe, Whalen, Colvin, Chiechi, Laro, Gale, and Thornton, JJ., agree with the majority opinion. Sec. 167(

m) was deleted from the Internal Revenue Code by the Omnibus Budget Reconciliation Act of 1990, Pub. L. 101-508, sec. 11812(a)(1), 104 Stat. 1388-534. A notice of proposed rulemaldng was pubbshed in the Federal Register on Mar. 13, 1971, 36 Fed. Reg. 4885, and a Treasury Decision setting forth final regulations was published in the Federal Register on June 23, 1971, 36 Fed. Reg. 11924. See T.D. 7128, 1971-2 C.B. 132. The final regulations were subsequently modified, in 1973, to conform the ADR system to sec. 167(m). See T.D. 7272,1973-1 C.B. 82. Rev.

Proc. 87-56, 1987-2 C.B. 674, was issued to take into account amendments made to sec. 168 as part of the Tax Reform Act of 1986, Pub. L. 99-514, sec. 201,100 Stat. 2121. The recovery periods assigned to property within 13.2 and 46.0 are in accordance with sec. 168(c)(1) and (e)(1), which, together, provides that the recovery period for property with a class life of 10 or more years but less than 16 years is 7 years, and the recovery period for property with a class life of 20 or more years but less than 25 years is 15 years. For example, Rev.

Proc. 87-56, 1987-2 C.B. 674, provides that "assets used in the drilling of onshore oil and gas wells” are generally includable within asset class 13.1, which has a 6-year class life and a 5-year recovery period. Asset class 13.1 specifically excludes “assets used in the performance of any of these activities * * * by integrated petroleum and natural gas producers for their own account”.

Asset class 13.2, on the other hand, which specifically pertains to “assets used by petroleum and natural gas producers for drilling of wells and production of petroleum and natural gas” has a 14-year class life and a 7-year recovery period. An onshore oil drilling rig, therefore, has a shorter class life and recovery period if owned and used by a person whose sole activity is well drilling than it would have if owned and used by an integrated oil and gas producer.

The Court of Appeals for the Tenth Circuit distinguishes between “gathering pipelines”, which “fall within Asset Class 13.2”, and “trunk lines and related storage facilities”, which “fall within Asset Class 46.0”, stating that “it is undisputed that trunk lines and gathering systems are mutually exclusive terms referring to different types of pipeline systems.” Duke Energy Natural Gas Corp. v. Commissioner, 172 F.3d 1255, 1259 (10th Cir. 1999), revg. 109 T.C. 416 (1997). Petitioner argues that Clajon’s trunk lines are part of its gathering system and, like the rest of the system, must be included within 13.2.

Petitioner urges that we distinguish the Court of Appeals’ classification of trunk lines on the basis that that court must have considered Duke Energy’s trunk lines to be transmission rather than gathering pipelines. Because we conclude that all of the pipelines in the Texas gathering systems fall within 46.0, we need not address the Court of Appeals’ refusal to treat trunk lines as part of the gathering system for asset classification purposes.

In concluding that petitioner’s trunk fines are includable within 46.0, we obviously reject petitioner’s suggestion that the specific inclusion, within 46.0, of "trunk lines * * * of integrated * * * natural gas producers” necessarily implies the exclusion of its trunk lines from that asset class (since it is not an integrated natural gas producer). We view the quoted language as simply intended to clarify that an integrated producer’s trunk lines are not to be considered gathering pipelines includable within 13.2.

That language has no bearing upon the inclusion, within 46.0, of trunk lines owned and used by a pipeline company like petitioner. The parties have stipulated that Clajon owns no oil or natural gas reserves, nor does it own an economic interest in the wells connected to the Texas gathering systems. Generally, as in this case, the taxpayer is the owner of the property. See, however, sec. I.167(a)-4, Income Tax Regs., which provides for lessee depreciation of permanent leasehold improvements to a lessor-owner’s premises; see also Depot Investors, Ltd. v. Commissioner, T.C.

Memo. 1992-145 (allowing lessee cost recovery of a leasehold improvement over the remaining lease term). Sec. 1.167(a)-11(b)(1), Income Tax Regs., provides: “The allowance for depreciation of eligible property * * * to which the taxpayer elects to apply this

section shall * * * constitute the reasonable allowance for depreciation of such property under

section 167(a).” (Emphasis added.) Although Clajon is a partnership and, thus, not itself subject to the income tax, see sec. 701 (partners not partnership subject to income tax), the depreciation deduction is taken in computing Clajon’s taxable income, see sec. 703(a), and the regulations provide that, if a partnership places eligible property in service, the partnership is to make the election to apply sec. 1.167(a)-II, Income Tax Regs., sec. 1.167(a)-ll(e)(3)(ii), Income Tax Regs.

Under that rationale, the fact that the property in question is leased would have no bearing whatsoever on the determination of the asset guideline class for such property, for it is of no consequence whether the lessor or lessee of property is considered the owner if, as stated by the Court of Appeals for the Tenth Circuit in Duke Energy Natural Gas Corp. v. Commissioner, 172 F.3d at 1259, primary use of the property is unrelated to ownership. Some of the asset guideline classes set forth in Rev.

Proc. 87-56,1987-2 C.B. 674, are based upon the type of property (such as trucks or railroad cars) as distinguished from the activity in which property is used. The dissenters assume that, as described by Judge Foley, the “central issue” in this case is whether Clajon’s gathering pipelines were “used by * * * producers for * * * production of * * * natural gas”. Judge Foley, finding no ambiguity in the verb “to use”, criticizes us for failing to be governed by the “plain language” of 13.2.

The dissenters ignore the fact that a similar criticism could be leveled against them, since the plain language of 46.0, which includes “assets used in * * * carrying * * * gas” (emphasis added), unambiguously includes Clajon’s pipelines. Assuming, arguendo, that the producers use Clajon’s pipelines (rather than simply benefit from Clajon’s own use of its pipelines), the “central issue” is which use — the producers’ or Clajon’s— controls the determination of the proper recovery period. The proper inquiry is not whether 13.2 is or is not ambiguous but, rather, whether 13.2 is applicable at all.

The dissenters’ reliance on the plain language of 13.2 to support their analysis is also undercut by their ultimate reliance not on the plain language of 13.2 but on the regulations, which clarify that the primary use of property controls its classification under Rev. Proc. 87-56, 1987-2 C.B. 674. Moreover, the dissenters fail to reconcile their plain language analysis with the special rule for leased property found in sec. 1.167(a)-ll(e)(3)(iii), Income Tax Regs.

That rule, which, in effect, looks to the lessee’s primary use of property in determining its proper asset guideline class, necessarily implies that, under the general rule applicable to nonleased property (i.e., under the first sentence of sec. 1.167(a) — 1 l(b)(4)(iii)(6), Income Tax Regs.), it is the owner-taxpayer’s primary use of property that determines its proper asset guideline class. Thus, Judge Foley’s

interpretation of the third sentence of sec. 1.167(a) — 1 l(b)(4)(iii)(6), Income Tax Regs., as referencing the insubstantiality of anyone’s primary use of property in relation to all of the taxpayer’s activities is not sustainable. Moreover, we note that, had Clajon leased rather than owned its gathering systems, the lessor would have been required by the regulations to treat Clajon’s (not the producers’) primary use of such systems as controlling the determination of the proper asset guideline class.

There is no conceivable basis for interpreting sec. 1.167(a)-ll(b)(4)(iii)(6), Income Tax Regs., as treating the producer’s primary use as controlling where the pipeline company owns rather than leases its gathering systems. In our discussion to this point, we have not distinguished between the pipelines, compression stations, and metering installations constituting what we have termed “the gathering pipelines”.

Although respondent made separate adjustments with respect to such components, the adjustments were similar, and the bulk of the adjustments (in excess of 90 percent) were with respect to the pipelines. (Less than 0.5 percent were with respect to the meter runs.) We have had no need to distinguish among the components since the issue is whether petitioner is a natural gas producer, not whether the components of its gathering system are within the meaning of the term “gathering pipelines” as it is used in 13.2.

With respect to the placement of such components within 46.0, certainly Clajon’s primary use of its pipelines was in carrying or transporting gas. Moreover, because the sole function of field compression is, in the words of petitioner’s expert, “to push the gas from one location to another through the gathering system”, the same is true of Clajon’s compressor stations. The so-called meter runs are not separately discussed in either the trial record or the briefs.

However, if they are simply meters used to ascertain the quantity of gas flowing through the pipelines (the definition of a “meter” set forth in Williams & Meyers, Manual of Oil and Gas Terms 626 (11th ed. 2000)), we see no reason to differentiate them from the pipelines in terms of primary use. Although we have found that Clajon’s gathering pipelines are ineligible for inclusion within 13.2, a finding that such pipelines are primarily production related might justify their classification (in the hands of a nonproducer) as “Personal Property With No Class Life” entitled to the same 7-year recovery period.

See Rev. Proc. 87-56, 1987-2 C.B. 674, 687. Petitioner has not on brief argued for such classification. Distribution pipelines, like transmission pipelines, carry lean gas. They are fed by transmission pipelines and connect to the premises of the ultimate consumers of the gas. See Williams & Meyers, Manual of Oil and Gas Terms 290-291 (11th ed. 2000). There is nothing in the record to indicate that the useful life of gathering pipelines is so short that placing them in the same asset class as transmission and distribution pipelines would be somehow inappropriate.

Respondent’s principal expert did not disagree with the statement by petitioner’s expert that the life of a natural gas gathering system cannot exceed the life of the gas field or fields that it serves.

Respondent’s expert stated, however, that gas gathering areas are extended and gathering pipelines are added to the system as new wells are developed within the field, a process that “may continue for * * * 50 years or more.” He also noted that “new technology or enhanced recovery can extend the life of an oil or gas field, which will extend the life of a gathering system.” Such longevity is exemplified by Clajon’s Southeast Texas Pipeline System, which has been in operation since the late 1970s.

It is also a fact that gathering pipelines transporting lean gas directly to customer transmission lines (such as those constituting Clajon’s five smaller gathering systems) are not subject to the corrosive elements that tend to shorten pipeline useful life. Moreover, the experts appeared to agree that even pipelines carrying raw gas remain in service throughout the life of the gas field or fields that they serve.

In its petition, petitioner argues, in the alternative, that most of Clajon’s “gas gathering assets may also be properly classified in Asset Guideline Class 49.23”, which provides a 14-year class life and a 7-year recovery period for “Natural Gas Production Plant”. Rev. Proc. 87-56, 1987-2 C.B. 674, 686. Petitioner has failed to pursue its alternative argument on brief. We conclude, therefore, that petitioner has abandoned its alternative argument. See Nicklaus v. Commissioner, 117 T.C. 117, 120 n.4 (2001).
