Abstract
EPA is taking direct final action approving a State Implementation Plan (SIP) revision submitted by the State of Arizona on April 29, 1997, establishing a summertime gasoline Reid Vapor Pressure (RVP) limit of 7.0 pounds per square inch (psi) for gasoline distributed in the Maricopa County (Phoenix) ozone nonattainment area. Arizona has lowered the summertime RVP limit for this area to reduce emissions of volatile organic compounds (VOC) in accordance with the requirements of the Clean Air Act, as amended in 1990 (CAA). Arizona's fuel requirement is not preempted by federal fuels requirements because EPA is finding that the control measure is necessary for the Maricopa area to attain the national ambient air quality standards (NAAQS) for ozone and is approving the measure into the Arizona SIP.
