Riepilogo

The Environmental Protection Agency (EPA) is taking direct final action to approve revisions to the South Coast Air Quality Management District (SCAQMD) and Yolo-Solano Air Quality Management District (YSAQMD) portions of the California State Implementation Plan (SIP). These revisions concern emissions of volatile organic compounds (VOCs) from motor vehicle and mobile equipment refinishing coating operations. We are approving local rules that regulate these emission sources under the Clean Air Act (CAA or the Act).
