The Environmental Protection Agency (EPA) is taking final action on a permitting rule submitted as a revision to the San Joaquin Valley Air Pollution Control District (SJVAPCD or ``District'') portion of the California state implementation plan (SIP). We are finalizing a limited approval and limited disapproval of the rule. This revision concerns the District's new source review (NSR) permitting program for new and modified sources of air pollution under section 110(a)(2)(C) and part D of title I of the Clean Air Act (CAA or ``Act'').
