Air Plan Conditional Approval; Arizona; Maricopa County
The Environmental Protection Agency (EPA) is proposing to conditionally approve revisions to the Maricopa County Air Quality Department (MCAQD or the County) portion of the Arizona State Implementation Plan (SIP). These revisions concern emissions of volatile organic compounds (VOCs) from organic liquid and gasoline storage and transfer operations. We are proposing to conditionally approve local rules to regulate these emission sources under the Clean Air Act (CAA or the Act) and conditionally approve the County's demonstration regarding Reasonably Available Control Technology (RACT) requirements for the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS) in the Phoenix-Mesa ozone nonattainment area, with respect to petroleum liquid storage and gasoline transfer and transport. We are taking comments on this proposal and plan to follow with a final action.
