Approval of California Air Plan Revisions, Yolo-Solano Air Quality Management District

The Environmental Protection Agency (EPA) is proposing to approve a revision to the Yolo-Solano Air Quality Management District (YSAQMD or ``District'') portion of the California State Implementation Plan (SIP). This revision concerns emissions of volatile organic compounds (VOCs) from architectural coatings. We are proposing to approve a local rule to regulate these emission sources under the Clean Air Act (CAA or the Act). We are taking comments on this proposal and plan to follow with a final action.
