The Environmental Protection Agency (EPA) is taking three separate final actions related to a state implementation plan (SIP) revision submitted by the State of South Carolina, through the South Carolina Department of Health and Environmental Control (SC DHEC), on April 17, 2015. These final actions are for the York County, South Carolina portion of the bi-state Charlotte-Rock Hill, North Carolina- South Carolina 2008 8-hour ozone national ambient air quality standards (NAAQS) nonattainment area (the entire area is hereinafter referred to as the "bi-State Charlotte Area" or "Area" and the South Carolina portion is hereinafter referred to as the "York County Area"). In these three final actions, EPA determines that the bi-state Charlotte Area is continuing to attain the 2008 8-hour ozone NAAQS; approves and incorporates South Carolina's plan for maintaining attainment of the 2008 8-hour ozone standard in the York County Area, including the 2014 and 2026 motor vehicle emission budgets (MVEBs) for nitrogen oxides (NO<INF>X</INF>) and volatile organic compounds (VOC) for the York County Area, into the SIP; and redesignates the York County Area to attainment for the 2008 8-hour ozone NAAQS. Additionally, EPA finds the 2014 and 2026 MVEBs for the York County Area adequate for the purposes of transportation conformity.
