The Environmental Protection Agency (EPA) is proposing approval of revisions to the Clean Air Act (CAA or "Act") Operating Permit Program (title V) of the San Diego County Air Pollution Control District (SDCAPCD or "District") in California. Once approved, these revisions will update the District's public noticing requirements to conform to current federal requirements for title V programs. We are taking comments on these proposed revisions and are simultaneously publishing our final action approving these revisions in a direct final rule.
