On June 18, 2025, the Supreme Court decided EPA v Calumet Shreveport Refining, LLC et al., and its companion case Oklahoma et al. v. EPA, clarifying the tripartite framework for determining venue in Clean Air Act (“CAA” or “Act”) litigation.  Looking at the CAA's venue provision (42 U.S.C. 7607(b)(1)), the Court explained that if a challenge is to an “nationally applicable” EPA action the challenge should be directed to the U.S. Circuit Court of Appeals for the D.C. Circuit and the matter ends there.  But, if the challenge is to a “locally or regionally applicable” EPA action, then typically those challenges belong in the relevant regional Circuit Court.  However, when a “locally or regionally applicable” action falls within the “nationwide scope or effect” exception, which requires the action be (1) “based on a determination of nationwide scope or effect” and (2) accompanied by an EPA finding to the same effect, the Court instructed that the matter should be routed back to the D.C. Circuit.  Applying this understanding of CAA's venue provision, the Court reached different conclusions in Calumet and Oklahoma, finding respectively that the “nationwide scope or effect” exception applied in one instance and not in the other.

On June 25, 2021, the Supreme Court, reversing the Tenth Circuit, held that a small refinery that had previously received an exemption from certain requirements of the renewable fuel standard (“RFS”) program was eligible for an extension of that exemption, even if it had had a lapse in coverage in previous years. See HollyFrontier Cheyenne Refining, LLC, v. Renewable Fuels Association, et al., Slip Op. 20-472 (June 25, 2021). Petitioners, three small fuel refineries, had each applied for a hardship exemption under the RFS program, and the Environmental Protection Agency (“EPA”) had granted each request. Those exemptions were then challenged by a group of renewable fuel producers. The Tenth Circuit ultimately sided with the renewable fuel producers, holding that because each refinery had allowed its previously held exemption to lapse at times in the past, each was no longer eligible to receive an extension of the original exemption. After hearing oral argument in April 2021, the Supreme Court reversed the Tenth Circuit and held that the text of the statute does not require that the exemption be continually held in order to remain valid.
