EPA is taking final action to determine that the Atlanta, Georgia 1997 8-hour ozone nonattainment area has attained the 1997 8- hour ozone national ambient air quality standards (NAAQS) based on quality assured, quality controlled monitoring data from 2008-2010. The Atlanta, Georgia 1997 8-hour ozone nonattainment area (hereafter referred to as the "Atlanta Area" or "the Area") is comprised of Barrow, Bartow, Carroll, Cherokee, Clayton, Cobb, Coweta, Dekalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Hall, Henry, Newton, Paulding, Rockdale, Spalding and Walton Counties in Georgia. This determination is based upon complete, quality assured, quality controlled, and certified ambient air monitoring data for the years 2008-2010 showing that the Atlanta Area has monitored attainment of the 1997 8-hour ozone NAAQS. The requirement for the State of Georgia to submit an attainment demonstration and associated reasonably available control measures (RACM) analyses, reasonable further progress (RFP) plans, contingency measures, and other planning State Implementation Plans (SIPs) related to attainment of the 1997 8-hour ozone NAAQS for the Atlanta Area, shall be suspended for as long as the Area continues to meet the 1997 8-hour ozone NAAQS.
