Abstract
EPA is approving a state implementation plan (SIP) revision submitted by the State of Arizona on June 13, 2007, to demonstrate attainment of the 1997 8-hour ozone national ambient air quality standards (NAAQS) in the Phoenix-Mesa nonattainment area by June 15, 2009. This action was proposed in the Federal Register on April 11, 2012. EPA is approving the submitted SIP revision based on our determination that it contains all of the SIP elements required for ozone nonattainment areas under title I, part D, subpart 1 of the Clean Air Act (CAA) for the 1997 8-hour ozone NAAQS.
