Approval and Promulgation of Implementation Plans and Designation of Areas for Air Quality Planning Purposes; Georgia: Redesignation of Murray County, GA, 8-Hour Ozone Nonattainment Area to Attainment for Ozone

요약

EPA is taking final action to approve a request submitted on June 15, 2007, from the State of Georgia, through the Georgia Environmental Protection Division (EPD), to redesignate the Murray County 8-hour ozone nonattainment area to attainment for the 8-hour ozone National Ambient Air Quality Standard (NAAQS). The Murray County 8-hour nonattainment ozone area is a partial county area, comprised of the portion of Murray County that makes up the Chattahoochee National Forest (Murray County Area). EPA's approval of the redesignation request is based on the determination that the Murray County Area has met the criteria for redesignation to attainment set forth in the Clean Air Act (CAA), including the determination that the Murray County Area has attained the 8-hour ozone standard. Additionally, EPA is approving a revision to the Georgia State Implementation Plan (SIP) including the 8-hour ozone maintenance plan for the Murray County Area that contains the new 2018 motor vehicle emission budgets (MVEBs) for nitrogen oxides (NO X ) and volatile organic compounds (VOCs). Through this action, EPA is also finding the 2018 MVEBs adequate for the purposes of transportation conformity.
