On January 19, 2016, the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC), Air Pollution Control Division, submitted a request for the Environmental Protection Agency (EPA) to redesignate the portion of Tennessee that is within the Memphis, Tennessee-Mississippi-Arkansas (Memphis, TN-MS-AR) 2008 8-hour ozone nonattainment area (hereafter referred to as the "Memphis, TN-MS-AR Area" or "Area") and a related State Implementation Plan (SIP) revision containing a maintenance plan and base year inventory for the Area. EPA is taking the following separate final actions related to the January 19, 2016, redesignation request and SIP revision: Approving the base year emissions inventory for the Area into the SIP; determining that the Memphis, TN-MS-AR Area is attaining the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS); approving the State's plan for maintaining attainment of the 2008 8-hour ozone NAAQS in the Area, including the motor vehicle emissions budgets (MVEBs) for nitrogen oxides (NO<INF>X</INF>) and volatile organic compounds (VOCs) for the year 2027 for the Tennessee portion of the Area, into the SIP; and redesignating the Tennessee portion of the Area to attainment for the 2008 8-hour ozone NAAQS. Additionally, EPA finds the MVEBs for the Tennessee portion of the Area adequate for the purposes of transportation conformity.
