As published in the Federal Register on 08/27/2015, EPA is proposing to redesignate 36 Ozone Nonattainment Areas, including Atlanta. Based on the 2012-2014 design value, EPA determined that Atlanta did not attain the 2008 ozone NAAQS by July 20, 2015, thereby triggering a “bump up” in nonattainment classification from marginal to moderate. The new attainment date is July 20, 2018. The proposed SIP submittal due date is January 1, 2017 or March 1, 2017 (comment solicited). Several federal standards, including CSAPR, Tier 3 vehicle standards, and Boiler MACT, are expected to support attainment efforts. However, state agencies could find that additional NOx or VOC control measures (RACT rules) are needed. Georgia EPD has indicated that it intends to certify 2013-2015 ozone monitoring data in support of a request to redesignate to attainment.
