## Abstract

The Environmental Protection Agency (EPA) is taking final action to approve revisions to the San Diego Air Pollution Control District (SDAPCD) portion of the California State Implementation Plan (SIP). These revisions concern emissions of volatile organic compounds (VOCs) from cold solvent cleaning and stripping operations, and from vapor degreasing operations. We are approving revisions to local rules that regulate these emission sources under the Clean Air Act (CAA or the Act).
