EPA is taking direct final action to approve revisions to the San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD), and South Coast Air Quality Management District (SCAQMD) portions of the California State Implementation Plan (SIP). These revisions concern volatile organic compound (VOC) and oxides of nitrogen (NO<INF>X</INF>) emissions from equipment tuning procedure for boilers, steam generators, and process heaters, pumps and compressor seals at petroleum refineries and chemical plants, and residential type, natural gas-fired water heaters. We are proposing to approve local rules to regulate these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act). We are approving local rules that regulate these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).
