Revisions to the California State Implementation Plan, Antelope Valley Air Quality Management District

The Environmental Protection Agency (EPA) is taking direct final action to approve revisions to the Antelope Valley Air Quality Management District (AVAQMD) portion of the California State Implementation Plan (SIP). These revisions largely concern volatile organic compound (VOC) emissions from graphic arts facilities and aerospace assembly and coating operations. We are approving local rules that regulate these emission sources under the Clean Air Act (CAA or the Act). These revisions also address rescission of two rules no longer required, and administrative revisions to the emergency episode plan requirements.
