Summary
A short, plain-English overview of Oklahoma v. EPA.
In Oklahoma v. EPA, the Supreme Court reviewed whether the Environmental Protection Agency's (EPA) disapprovals of state implementation plans (SIPs) for Oklahoma and Utah under the Clean Air Act were locally or regionally applicable actions. The EPA had aggregated these disapprovals into a single rule, asserting they were nationally applicable. The Court determined that each SIP disapproval is a separate action and should be reviewed in regional circuits, not the D.C. Circuit, as they are locally or regionally applicable actions.
