Courthouse Steps Oral Argument: Oklahoma v. EPA and EPA v. Calumet Shreveport Refining, LLC

On March 25th, 2025, the Supreme Court will hear oral argument to resolve two circuit splits arising under the Clean Air Act (CAA) provision regarding judicial venue: EPA v. Calumet Shreveport Refining, L.L.C. (23-1229), and Oklahoma v. EPA (23-1067). The outcome of these cases will hinge on the Court’s interpretation of the CAA’s unique venue provision, 42 U.S.C. § 7607(b)(1). The CAA states that challenges to “nationally applicable” actions may be filed only in the D.C. Circuit. 42 U.S.C. § 7607(b)(1). Conversely, challenges to CAA actions that are “locally or regionally applicable” may generally be filed only in the appropriate circuit court for the region. Id. But there is an exception: actions that are “based on a determination of nationwide scope or effect” must be filed in the D.C. Circuit “if in taking such action the Administrator finds and publishes that such action is based on such a determination.” Id.What is the meaning and scope of this exception? How far may EPA go in picking where to litigate its final actions? And what does this mean for denials of State Implementation Plans (SIPs), small oil refineries seeking Renewable Fuel Standard (RFS) exemptions, and other EPA actions affecting the regulated community?
