What the agency says

The Environmental Protection Agency (EPA) is proposing a limited approval and limited disapproval of revisions to the Maricopa County Air Quality Department (MCAQD or "County") portion of the Arizona State Implementation Plan (SIP). These revisions concern emissions of volatile organic compounds (VOC) from loading of organic liquids and gasoline. We are proposing action on local rules to regulate these emission sources under the Clean Air Act (CAA or "Act"). We are also proposing to disapprove the MCAQD's reasonably available control technology (RACT) demonstration for the source categories associated with these rules for the 2008 8-hour ozone national ambient air quality standards (NAAQS) in the Phoenix-Mesa ozone nonattainment area. We are taking comments on this proposal and plan to follow with a final action.
