## Abstract

The Environmental Protection Agency (EPA) is taking final action on four permitting rules submitted as a revision to the San Diego County Air Pollution Control District (SDAPCD or "District") portion of the California State Implementation Plan (SIP). We are finalizing a limited approval and limited disapproval of one rule and approval of the remaining three rules. These revisions concern 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). This action updates the SDAPCD's applicable SIP with revised rules that the District has amended to address deficiencies identified in a previous conditional approval action.
