Oral Argument: Oklahoma v. EPA | Case No. 23-1067 | Date Argued: 3/25/25
Case Info: Oklahoma v. EPA | Case No. 23-1067 | Date Argued: 3/25/25
Link to Docket: Here.
Background:
Under the Clean Air Act, each state must adopt an implementation plan to meet national standards, which EPA then reviews for compliance with the Act. See 42 U.S.C. § 7410. In 2023, EPA published disapprovals of 21 states' plans implementing national ozone standards. It did so in a single Federal Register notice. The Act specifies that "[a] petition for review of the [EPA's] action in approving or promulgating any implementation plan ... or any other final action of the [EPA] under this Act ... which is locally or regionally applicable may be filed only in" the appropriate regional circuit, while "nationally applicable regulations ... may be filed only in" the D.C. Circuit. 42 U.S.C. § 7607(b)(1). Parties from a dozen states sought judicial review of their respective state plan disapprovals in their appropriate regional circuits.
The Fourth, Fifth, Sixth, and Eighth Circuits held that the implementation plan disapprovals of states within those circuits are appropriately challenged in their respective regional courts of appeals. In the decision below, the Tenth Circuit held that challenges to the disapprovals of Oklahoma's and Utah's plans can only be brought in the D.C. Circuit, explicitly disagreeing with the decisions of its sister circuits.
Questions Presented:
- Whether a final action by EPA taken pursuant to its Clean Air Act authority with respect to a single state or region may be challenged only in the D.C. Circuit because EPA published the action in the same Federal Register notice as actions affecting other states or regions and claimed to use a consistent analysis for all states.
- Whether the Environmental Protection Agency's disapproval of a State Implementation Plan may only be challenged in the D.C. Circuit under 42 U.S.C. § 7607 (b)(1) if EPA packages that disapproval with disapprovals of other States' SIPs and purports to use a consistent method in evaluating the state-specific determinations in those SIPs.
Host Note: Consolidated with: Pacificorp V. EPA, Case No. 23-1067.
