Automated Summary
Key Facts
The Supreme Court held that the Environmental Protection Agency's (EPA) disapprovals of Oklahoma and Utah's state implementation plans (SIPs) under the Clean Air Act's 'Good Neighbor' provision are locally or regionally applicable actions, requiring review in the Tenth Circuit (the regional Circuit) rather than the D.C. Circuit. The EPA disapproved 21 states' SIPs for failing to address cross-state ozone pollution, but the Court determined these decisions were based on state-specific analyses, not nationwide determinations, and thus do not trigger the 'nationwide scope or effect' exception to the venue rule. The Tenth Circuit's earlier transfer to the D.C. Circuit was reversed.
Issues
The Supreme Court addressed the proper venue for challenges to the Environmental Protection Agency's (EPA) disapprovals of state emissions-control plans under the Clean Air Act (CAA) §7607(b)(1). The core issue was whether these disapprovals are 'nationally applicable' actions (reviewable in the D.C. Circuit) or 'locally or regionally applicable' actions (reviewable in regional Circuits). The Court also evaluated whether the 'nationwide scope or effect' exception, which would override the default regional review for locally applicable actions, was satisfied. The Court applied its two-step framework from EPA v. Calumet, concluding that each EPA SIP disapproval is a locally or regionally applicable action and that the nationwide exception did not apply due to the state-specific nature of the disapprovals.
Holdings
- The Court further held that the 'nationwide scope or effect' exception to the regional Circuit review requirement does not apply because EPA's disapprovals were primarily driven by state-specific factual analyses rather than national determinations. While EPA cited four nationwide factors as justifications, the Court found these served as analytical tools rather than primary decision drivers, distinguishing this case from EPA v. Calumet where uniform national standards triggered the exception.
- The Supreme Court held that the Environmental Protection Agency's (EPA) disapprovals of Oklahoma and Utah's state implementation plans (SIPs) under the Clean Air Act's 'Good Neighbor' provision are locally or regionally applicable actions reviewable in a regional Circuit, not the D. C. Circuit. The Court rejected EPA's argument that its omnibus rule constituted a single, nationally applicable action, emphasizing that each SIP disapproval is a discrete action tied to state-specific analyses and does not meet the 'nationwide scope or effect' exception.
Remedies
The Supreme Court reversed the Tenth Circuit's judgment transferring the cases to the D.C. Circuit, holding that the EPA's SIP disapprovals are locally or regionally applicable actions reviewable in a regional Circuit. The cases were remanded for further proceedings consistent with the opinion.
Legal Principles
The Court applied the principle of 'substance over form' in determining the proper venue for challenges to EPA actions under the Clean Air Act. It held that the relevant 'action' is defined by the underlying CAA provision and the nature of EPA's exercise of authority, rather than how the action is packaged in the Federal Register. This approach rejects treating an omnibus rule as a single 'action' when the statute treats individual SIP approvals and disapprovals as discrete, state-specific decisions.

Passage Text
- Here too, we conclude that each EPA SIP disapproval constitutes its own 'action.' We therefore reject EPA's contention, adopted by the Tenth Circuit, that EPA's omnibus rule should be treated as a single 'action.' Instead, we have before us two distinct 'actions'—EPA's respective disapprovals of the Oklahoma and Utah SIPs.
- We agree with EPA that these conclusions qualify as determinations of nationwide scope or effect, in that they are conclusions that apply nationwide, either formally or as a practical matter given EPA's rejection of alternative approaches. But, these conclusions are at most heuristics that aided EPA's analysis, as opposed to the primary drivers of its disapprovals.
- EPA's omnibus rule makes clear that its SIP disapprovals were based on 'a number of intensely factual determinations' particular to the State at issue. ... Based on these and other reasons, EPA concluded that each State had failed to submit a SIP with 'the necessary provisions to eliminate emissions' consistent with that State's Good Neighbor obligations.
