Abstract
EPA is taking direct final action to approve revisions to the South Coast Air Quality Management District (SCAQMD) and Sacramento Metropolitan Air Quality Management District (SMAQMD) portion of the California State Implementation Plan (SIP). These revisions concern oxides of nitrogen (NOx) emissions from boilers, process heaters, steam generators and residential water heaters. We are approving local rules that regulate these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).
