Description: 

The Environmental Protection Agency (EPA) is proposing to approve revisions to the Maricopa County Air Quality Department (MCAQD or ``County'') portions of the Arizona State Implementation Plan (SIP). These revisions concern the County's reasonably available control technology (RACT) demonstration for the aerospace coating category (``aerospace operations RACT certification'') and negative declarations for the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS or ``standards'') in the portion of the Phoenix-Mesa ozone nonattainment areas regulated by the MCAQD, as well as a rule covering emissions of volatile organic compounds (VOCs) from surface coatings and industrial adhesives. We are proposing to approve the SIP revisions under the Clean Air Act (CAA or ``the Act''). We are taking comments on this proposal and plan to follow with a final action.
