Abstract
EPA is taking final action approving a State Implementation Plan (SIP) revision submitted by the State of Arizona on September 15, 1997, establishing Cleaner Burning Gasoline (CBG) fuel requirements for gasoline distributed in the Phoenix (Maricopa County) ozone nonattainment area. Arizona has developed these fuel requirements to reduce emissions of volatile organic compounds (VOC) and particulates (PM<INF>10</INF>) in accordance with the requirements of the Clean Air Act (CAA). EPA is approving Arizona's fuel requirements into the Arizona SIP because either they are not preempted by federal fuels requirements, or to the extent that they are or may be preempted, EPA finds that the requirements are necessary for the Maricopa area to attain the national ambient air quality standards (NAAQS) for ozone and particulates. EPA intends to publish a separate document in the Federal Register approving Arizona's opt-out from the federal reformulated gasoline (RFG) program to be effective 90 days from the effective date of this EPA final action.
