Rescission of Title V Emergency Affirmative Defense Rule; Corrections

What it does

On June 1, 2026, the U.S. Environmental Protection Agency (EPA) published a final rule titled "Rescission of Title V Emergency Affirmative Defense Rule." After publication, the EPA discovered inadvertent typographical errors in the action. This document corrects the errors and ensures the regulatory text restored on June 1, 2026, matches the original regulatory text codified in Federal regulations prior to their removal following the 2023 Affirmative Defense Rule. The corrections described in this action do not affect the emergency affirmative defense provisions codified in 40 CFR parts 70 and 71 in a substantive way.
