Approval of California Air Plan Revisions, Imperial County Air Pollution Control District

The Environmental Protection Agency (EPA) is proposing to approve revisions to the Imperial County Air Pollution Control District (ICAPCD) portion of the California State Implementation Plan (SIP). These revisions concern emissions of volatile organic compounds (VOCs) and particulate matter (PM) from large confined animal facilities (LCAFs). We are proposing to approve local rules 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.
