## Abstract

EPA is taking direct final action to approve revisions to the San Diego Air Pollution Control District portion of the California State Implementation Plan (SIP). These revisions concern volatile organic compound (VOC) emissions from cold solvent cleaning and vapor degreasing operations. We are approving two local rules that regulate these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).
