EPA Proposed Approval: Antelope Valley Air Quality Management District New Source Review Permitting Rule
AI-generated summary for informational purposes only. Not legal advice. See the original source for the authoritative text.
The U.S. Environmental Protection Agency (EPA) is proposing to approve a revised air permitting rule submitted by the Antelope Valley Air Quality Management District (AVAQMD) in California on October 16, 2025. This rule governs the New Source Review (NSR) permitting program, which regulates new and modified stationary sources of air pollution — such as factories, power plants, and industrial facilities — to ensure they meet Clean Air Act requirements before beginning or expanding operations. The AVAQMD previously submitted an earlier version of this rule, which the EPA identified as having regulatory deficiencies. In response, the District amended the rule and resubmitted it. Alongside this new proposed approval, the EPA is simultaneously withdrawing its earlier proposed 'limited approval and limited disapproval' of the prior version, effectively replacing it with this cleaner action. If finalized, the updated rule will be incorporated into California's State Implementation Plan (SIP) — the binding blueprint California uses to achieve and maintain federal air quality standards. The action is currently open for public comment, after which the EPA plans to issue a final rule.
