Energy Future Coalition v. Environmental Protection Agency, 793 F.3d 141

EPA regulation (40 C.F.R. §1065.701(c)) requires that fuels used for new-vehicle emissions testing be “commercially available,” implementing 42 U.S.C. §7525(h)’s requirement that tests reflect actual driving conditions.
Petitioners are biofuel producers and related parties seeking EPA approval to use E30 (≈30% ethanol) as a test fuel; EPA’s regulation currently bars non–commercially available fuels from test use.
Petitioners sued, arguing the “commercially available” requirement is arbitrary and capricious and creates a statutory Catch‑22 with other Clean Air Act provisions restricting sale of fuels not substantially similar to approved test fuels.
The D.C. Circuit addressed threshold jurisdictional questions: Article III standing, zone of interests, timeliness (60‑day filing), and ripeness, and rejected EPA’s challenges on each front.
On the merits, the court held EPA’s “commercially available” requirement is reasonable and aligned with the statutory goal of testing under conditions reflecting actual fuel use; petitioners’ Catch‑22 argument failed because any catch‑22 would stem from the statute, not the regulation.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Standing	Biofuel producers are injured because the regulation prevents E30 from being used as a test fuel, harming their ability to compete.	Regulation targets manufacturers, not producers, so producers lack concrete injury.	Petitioners have Article III standing: concrete injury, causation, and redressability established.
Zone of interests	Producers’ economic interests fall within the Clean Air Act’s protective scope and they can challenge test‑fuel rules.	EPA implied producers’ interests are peripheral to the Act’s objectives.	Petitioners lie within the Act’s zone of interests (not especially demanding test).
Timeliness & Ripeness	Petitioners filed within 60 days of final rule; the legal challenge is ripe because it raises purely legal questions.	EPA suggested review should await more concrete effects.	Suit was timely and ripe; the challenge presents purely legal reviewable issues.
Merits: Arbitrary & Capricious / Catch‑22	The “commercially available” requirement unlawfully blocks new fuels and creates a Catch‑22 with statutory sale restrictions.	It is reasonable to require test fuels reflect fuels actually used on roads; any Catch‑22 arises from the statute, not EPA’s regulation.	Court upheld the regulation as reasonable and not arbitrary or capricious; did not decide whether the statute compels or allows relaxation of the requirement.
