Determination of Attainment; Atlanta, Georgia; 2008 Ozone National Ambient Air Quality Standards

The Environmental Protection Agency (EPA) is taking final action to determine that the Atlanta, Georgia, 2008 Ozone National Ambient Air Quality Standard (NAAQS) Moderate Nonattainment Area ("Atlanta Area" or the "Area") has attained the 2008 8-hour ozone NAAQS. This final determination is based upon complete, quality- assured, and certified ambient air monitoring data showing that the Area has monitored attainment of the 2008 8-hour ozone NAAQS for the 2013-2015 monitoring period. The requirement for this Area to submit an attainment demonstration and associated reasonably available control measures (RACM), reasonable further progress (RFP) plans, contingency measures, and other planning state implementation plans (SIPs) related to attainment of the 2008 8-hour ozone NAAQS is suspended until EPA redesignates the Area to attainment, approves a redesignation substitute, or determines that the Area has violated the 2008 8-hour ozone NAAQS. This final attainment determination does not constitute a redesignation to attainment. The Atlanta Area will remain in nonattainment status for the 2008 8-hour ozone NAAQS until such time as the State requests a redesignation to attainment and EPA determines that the Atlanta Area meets the Clean Air Act (CAA or Act) requirements for redesignation, including an approved maintenance plan.
