Approval of California Air Plan Revisions, Placer County and Ventura County Air Pollution Control Districts

The Environmental Protection Agency (EPA) is taking final action to approve revisions to the Placer County Air Pollution Control District (PCAPCD) and Ventura County Air Pollution Control District (VCAPCD) portions of the California State Implementation Plan (SIP). These revisions concern emissions of oxides of nitrogen (NOX) from incinerators in the PCAPCD and previously unregulated types of fuel burning equipment in the VCAPCD. We are approving local rules that regulate these emission sources under the Clean Air Act (CAA or the Act).
