Court case · 1997
Duke Energy Natural Gas Corp. v. Commissioner
109 T.C. 416 (1997), rev'd 172 F.3d 1255 (10th Cir. 1999)
U.S. Tax Court, rev'd by U.S. Court of Appeals, 10th Circuit
Taxpayer won
The facts
Duke owned gathering systems that collect raw gas from wells and move it toward processing. The IRS put them in asset class 46.0, pipeline transportation, with a 15-year recovery period. The Tax Court agreed because Duke was not itself a gas producer.
What the court decided
The Tenth Circuit reversed. Gathering systems fit asset class 13.2, assets used in exploring for and producing petroleum and natural gas, with a 7-year recovery period. The asset's primary use and the plain words of the class descriptions controlled, not whether the owner was a producer.
Why it matters for your study: An asset's class follows what the asset does, not the owner's job title. That is a strong tool when the IRS argues for a longer life based on who owns the asset. It anchors recovery-period fights under Rev. Proc. 87-56.

IRS acquiescence: IRS Action on Decision issued on Duke Energy (irs.gov/pub/irs-aod/duke.pdf); corpus reports nonacquiescence at 1999-2 C.B. xvi
Background
Duke Energy Natural Gas Corp. owned gathering systems: the pipe networks that collect raw gas from wells and move it toward processing. Duke was not a gas producer itself. It owned and ran the gathering infrastructure.
The IRS classified the systems in asset class 46.0, pipeline transportation, with a 15-year recovery period. The Tax Court agreed at 109 T.C. 416 (1997), reasoning that because Duke was not a producer, its assets could not sit in the production class.
The difference between 7-year and 15-year recovery on systems this large made the appeal worth fighting.
What the court actually analyzed
The Tenth Circuit reversed at 172 F.3d 1255 (1999). It read the class descriptions in Rev. Proc. 87-56 by their plain words and matched them to the asset's primary use. Gathering systems serve the production process: they collect raw gas from wells. That puts them in asset class 13.2, assets used in exploring for and producing petroleum and natural gas, with a 7-year recovery period.
The court rejected the idea that the owner's status controls. Whether the owner is a producer does not change what the pipe does. Function drives classification.
The IRS issued an Action on Decision in response and did not embrace the result, but the rule spread anyway. The Sixth Circuit adopted it in Saginaw Bay in 2003 and the Eighth Circuit followed in Clajon in 2004. The IRS's own Cost Segregation Audit Techniques Guide now lists all three cases in its recovery-period discussion.
How it shows up in a study
Duke Energy is the lead case whenever a recovery-period call depends on matching an asset to the right class in Rev. Proc. 87-56. Its principle, classify by the asset's primary use, not the owner's line of business, reaches well beyond pipelines.
For energy and midstream properties, it directly supports 7-year treatment of gathering systems and related production-side assets. We cite the full trilogy, Duke, Saginaw Bay, and Clajon, so the examiner sees three circuits in agreement.
It is also a strong tool any time the IRS argues for a longer life based on who owns an asset rather than what the asset does. The plain words of the class description and the asset's actual function are the argument.
What it does not mean
Duke Energy does not give every pipeline a 7-year life. Transmission lines that move processed gas are still transportation assets. The case is about gathering systems, the production end of the chain.
It also does not mean the IRS welcomed the result. The government resisted, and only after two more circuit losses did the fight effectively end. On a new asset type, expect the function argument to be tested, and document the asset's primary use carefully.
And it is a recovery-period case under Rev. Proc. 87-56, not a section 1245 versus 1250 case. It tells you which class an asset belongs to, not whether an item is personal property in the first place.
