What the agency says

The Environmental Protection Agency (EPA) is proposing approval of one permitting rule, submitted on October 16, 2025, as a revision to the Antelope Valley Air Quality Management District (AVAQMD or "District") portion of the California State Implementation Plan (SIP). This revision concerns the District's New Source Review (NSR) permitting program for new and modified sources of air pollution under part D of title I of the Clean Air Act (CAA or "Act"). The AVAQMD amended and resubmitted the rule after the EPA identified deficiencies in an earlier proposed rulemaking on a previous submittal. In this action, the EPA is also withdrawing our proposed limited approval and limited disapproval of the previous version of this AVAQMD rule. If finalized, this action will update the AVAQMD's current SIP with the amended rule. We are taking comments on this proposal and plan to follow with a final action.
