Ohio v. Environmental Protection Agency Revisions: 6/27/24
Headline: Court blocks enforcement of EPA’s interstate ozone-control federal plan against certain states and companies, pausing costly compliance while appeals proceed in the D.C. Circuit and possible Supreme Court review.
Holding:
- Pauses enforcement of EPA’s interstate ozone-control federal plan against the applicants during appeals.
- Allows states and companies to avoid immediate costly compliance obligations while litigation proceeds.
- May delay air-quality improvements for downwind states until appeals and any Supreme Court review end.
Summary
Background
The dispute involves a federal plan the Environmental Protection Agency (EPA) adopted to control ozone that crosses state lines. After EPA tightened ozone standards in 2015, States had to submit new air-quality plans. EPA proposed to reject over 20 State plans and issued a single federal plan (FIP) intended to apply to 23 upwind States. Commenters warned that if some States were later excluded, EPA’s cost-effectiveness analysis might change. Several courts stayed 12 of the State disapprovals, leaving some applicants facing the FIP and seeking relief.
Reasoning
When asked to pause enforcement, the Court weighs four factors including whether applicants are likely to win on the merits. The Court concluded the applicants are likely to prevail on their claim that EPA’s final FIP was arbitrary or capricious because EPA did not reasonably explain why its nationwide cost-effectiveness analysis still applied after many States dropped out. EPA’s severability clause did not answer that core concern, and other defenses were rejected as inadequate. On that basis the Court granted the stay.
Real world impact
The ruling pauses enforcement of EPA’s FIP against the applicants while their appeals go forward in the D.C. Circuit and any timely Supreme Court review. That pause avoids immediate, potentially large compliance costs for those States and companies. The decision is an interim procedural ruling, not a final decision on the FIP’s legal validity.
Dissents or concurrances
A dissent argued the majority rushed emergency relief and that EPA’s methodology did not depend on the number of covered States, raising procedural and harmless-error objections to the stay.
