SUPPLEMENTARY INFORMATION:
I. What is the background for this action?
On November 6, 1991 56 FR 56694, EPA designated and classified the following counties in the Atlanta Area as a Serious ozone nonattainment area for the 1-hour ozone national ambient air quality standards NAAQS:
Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Forsyth,

Fulton, Gwinnett, Henry, Paulding, and Rockdale the Atlanta 1979 1-hour ozone Area. TCMs were implemented in the 13 counties comprising the Atlanta 1979 1-hour ozone Area.
Because the Atlanta 1979 1-hour ozone Area failed to attain the 1-hour ozone NAAQS by November 15, 1999, EPA
issued a final rulemaking action 68 FR
55469 on September 26, 2003, to reclassify the area to a Severe ozone nonattainment area. Subsequently, the Atlanta 1979 1-hour ozone Area attained the 1-hour ozone NAAQS, and thus EPA
redesignated the nonattainment area to attainment for the 1-hour ozone NAAQS. See 70 FR 34660 June 15, 2005. The 1979 1-hour ozone NAAQS
was revoked, effective June 15, 2005.
See 69 FR 23951 April 30, 2004.
On April 30, 2004 69 FR 23858, EPA
designated the following 20 counties in the Atlanta Area as a Marginal nonattainment area for the 1997 8-hour ozone NAAQS: Barrow, Bartow, Carroll, Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Hall, Henry, Newton, Paulding, Rockdale, Spalding, and Walton Atlanta 1997 8-hour ozone Area. The Atlanta 1979 1-hour ozone Area is a subset of this 20-county area.
EPA reclassified the Atlanta 1997 8hour ozone Area as a Moderate nonattainment area on March 6, 2008, because the area failed to attain the 1997
8-hour ozone NAAQS by the required attainment date of June 15, 2007. See 73
FR 12013. Subsequently, the Atlanta 1997 8-hour ozone Area attained the 1997 8-hour ozone standard, and on December 2, 2013, EPA redesignated the-Atlanta 1997 8-hour ozone Area to attainment for the 1997 8-hour ozone NAAQS. See 78 FR 72040. The 1997 8hour ozone NAAQS was revoked, effective April 6, 2015. See 80 FR 12264
March 6, 2015.
On May 21, 2012 77 FR 30088, EPA
designated the following 15 counties as Marginal nonattainment for the 2008 8hour ozone NAAQS: Bartow, Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Henry, Newton, Paulding, and Rockdale Atlanta 2008 8-hour ozone Area. The Atlanta 1979 1-hour ozone Area is a subset of the Atlanta 2008 8-hour ozone Area. The Atlanta 2008 8-hour ozone Area did not attain the 2008 8-hour ozone NAAQS by the attainment date of July 20, 2015, and therefore on May 4, 2016, EPA
reclassified the area from a Marginal nonattainment area to a Moderate nonattainment area for the 2008 8-hour ozone standard. See 81 FR 26697.
Subsequently, on July 14, 2016, EPA
determined that the Atlanta 2008 8-hour

ozone Area attained the 2008 8-hour ozone standard. See 81 FR 45419
determination that the area attained the standard, also known as a Clean Data Determination. EPA redesignated the Atlanta 2008 8-hour ozone Area to attainment for the 2008 8-hour ozone NAAQS. See 82 FR 25523.
On October 26, 2015 80 FR 65292, EPA revised the 8-hour ozone standard from 0.075 parts per million ppm to 0.070 ppm. Subsequently, on June 4, 2018 83 FR 25776, EPA designated the following seven Atlanta counties as Marginal nonattainment for the 2015 8hour ozone NAAQS: Bartow, Clayton, Cobb, Dekalb, Fulton, Gwinnett, and Henry Atlanta 2015 8-hour ozone Area. The seven counties comprising the Atlanta 2015 8-hour ozone Area were also part of the 13-county Atlanta 1979 1-hour ozone Area. Areas designated as Marginal nonattainment must attain the standard by August 3, 2021. Although the attainment date is August 3, 2021, Marginal areas must show attainment using air quality data for years 2018 through 2020.
Preliminary data indicates that the Atlanta Area will be able to attain the 2015 8-hour ozone NAAQS by the August 3, 2021, attainment deadline.1
On September 16, 2019, Georgia submitted a SIP revision requesting removal of certain TCMs from the Georgia SIP. The following TCMs have been approved into the Georgia SIP:
High Occupancy Vehicle HOV Lanes;
High Occupancy Toll Lanes; Atlantic Station; Express Bus Routes;
Improvements/Expansion of Bus Service; Park and Ride Lots; Transit Signal Preemption; Clean Fuel Buses;
Clean Fuels Revolving Loan Program;
