Description

The U.S. Environmental Protection Agency (EPA) is proposing a reconsideration of certain aspects of the January 2025 final rule concerning State Implementation Plan (SIP) submittal deadlines and requirements for reclassified nonattainment areas under the ozone National Ambient Air Quality Standards (NAAQS). The proposed rule interprets that, upon reclassification, areas are only subject to requirements specific to their current classification, not previous requirements. This proposed rule would apply nationwide to all past and future reclassifications associated with the 2008, 2015, and any future ozone NAAQS. The EPA is not reconsidering or reopening any other aspect of the January 2025 final rule in this rulemaking and is not addressing the scope of applicable requirements for NAAQS other than the ozone NAAQS.
