Case Info: EPA v. Calumet Shreveport Refining, L.L.C. | Case No. 23-1229 | Date Argued: 3/25/25 Link to Docket: Here . Background: In a pair of final actions, the United States Environmental Protection Agency (EPA) denied 105 petitions filed by small oil refineries seeking exemptions from the requirements of the Clean Air Act's Renewable Fuel Standard program. Six of those refineries petitioned for review of EPA's decisions in the Fifth Circuit, which denied the government's motion for transfer to the D.C. Circuit. Question Presented: Whether venue for the refineries' challenges lies exclusively in the D.C. Circuit because the agency's denial actions are "nationally applicable" or, alternatively, are "based on a determination of nationwide scope or effect." 42 U.S.C. 7607(b)(1). Holding: EPA's denials of small refinery exemption petitions are locally or regionally applicable actions that fall within the "nationwide scope or effect" exception, requiring venue in the D.C. Circuit. Result: Vacated and remanded. Voting Breakdown: 7-2. Justice Thomas delivered the opinion of the Court, in which Justices Alito, Sotomayor, Kagan, Kavanaugh, Barrett and Jackson joined. Justice Gorsuch filed a dissenting opinion in which Chief Justice Roberts joined. Link to Opinion: Here . Oral Advocates: For petitioner: Malcolm L.
