## Abstract

The Environmental Protection Agency (EPA) is finalizing a partial approval and partial disapproval of revisions to the Pinal County Air Quality Control District (PCAQCD) portion of the Arizona State Implementation Plan (SIP). This action concerns the District's demonstration regarding reasonably available control technology (RACT) requirements 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 area under the jurisdiction of the PCAQCD. The EPA is also finalizing a limited approval and limited disapproval of two PCAQCD rules that regulate emissions from surface coating operations and gasoline dispensing stations that were submitted with its RACT SIP demonstration. This partial disapproval of the RACT SIP and limited disapproval of two PCAQCD rules will trigger sanctions clocks under the CAA that will be stopped if the EPA approves subsequent SIP revisions that correct the rule and RACT SIP deficiencies within 18 months of the effective date of this final action. Under the authority of the Clean Air Act (CAA or the Act), this action simultaneously approves the PCAQCD rules for surface coating operations and storage and loading of gasoline at gasoline dispensing facilities and directs Arizona to correct the rule deficiencies.
