Approval of California Air Plan Revisions, South Coast Air Quality Management District

The Environmental Protection Agency (EPA) is taking final action to approve revisions to the South Coast Air Quality Management District (SCAQMD) portion of the California State Implementation Plan (SIP). These revisions concern emissions of oxides of nitrogen (NO<INF>X</INF>) from ovens, dryers, dehydrators, heaters, kilns, calciners, furnaces, crematories, incinerators, heated pots, cookers, roasters, smokers, fryers, closed and open heated tanks and evaporators, distillation units, afterburners, degassing units, vapor incinerators, catalytic or thermal oxidizers, soil and water remediation units, and other combustion equipment. We are finalizing our approval of local rules that regulate these emission sources under the Clean Air Act (CAA or the Act).
