Air Plan Revisions; Arizona; Maricopa County Air Quality Department; Volatile Organic Compounds; Solvent Cleaning

Riepilogo

The Environmental Protection Agency (EPA) is proposing to approve revisions to the Maricopa County Air Quality Department (MCAQD) portion of the Arizona State Implementation Plan (SIP). These revisions concern rules that regulate volatile organic compounds (VOC) emissions from solvent cleaning operations. We are proposing to approve the revisions under the Clean Air Act (CAA or "Act"). We are taking comments on this proposal and plan to follow with a final action.
