## Abstract

The Environmental Protection Agency (EPA) is taking direct final action to approve a revision to the Georgia State Implementation Plan (SIP) submitted by the Georgia Department of Natural Resources, Environmental Protection Division (GA EPD), on August 30, 2010, and a portion of the SIP revision submitted on July 25, 2014; and portions of revisions to the South Carolina SIP, submitted by the Department of Health and Environmental Control (SC DHEC) on December 15, 2014, August 12, 2015, and on November 4, 2016. The Georgia SIP revisions incorporate definitions relating to fine particulate matter (PM<INF>2.5</INF>), and amend state rules to reflect the 2008 national ambient air quality standard (NAAQS) for lead. The South Carolina SIP revisions incorporate the 2010 sulfur dioxide (SO<INF>2</INF>) NAAQS, 2010 nitrogen dioxide (NO<INF>2</INF>) NAAQS, 2012 PM<INF>2.5</INF> NAAQS, 2015 ozone NAAQS, removes the revoked 1997 8-hour ozone NAAQS, and remove the standard for gaseous fluorides from the SIP. This action is being taken pursuant to the Clean Air Act (CAA or Act).
