EPA is granting final approval of the 1-hour ozone redesignation request and the 10-year maintenance plan State Implementation Plan (SIP) revision, including the new 2015 Motor Vehicle Emission Budgets (MVEB) for the Atlanta severe 1-hour ozone National Ambient Air Quality Standard (NAAQS) nonattainment area, which were submitted by the Georgia Environmental Protection Division (EPD) on February 1, 2005. The current Atlanta severe 1-hour ozone nonattainment area consists of the following counties: Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Henry, Paulding, and Rockdale (Atlanta area). EPA's approval of the 1-hour ozone redesignation request is based on our determination that the Atlanta area has met the criteria for redesignation to attainment specified in the Clean Air Act (CAA or Act), including a demonstration that the Atlanta area has attained the 1-hour ozone NAAQS. EPA is granting final approval of the 10-year maintenance plan SIP revision, including the new 2015 MVEB, because EPA has determined that the plan complies with the requirements of section 175A of the Act. For transportation purposes, EPA is also finalizing its adequacy determination for the new 2015 MVEB. EPA has determined that the MVEB for the year 2015 are adequate for transportation conformity purposes.
