| 2010-25291 | Approval and Promulgation of Implementation Plans and Designation of Areas for Air Quality Planning Purposes; Tennessee; Redesignation of the Knoxville 8-Hour Ozone Nonattainment Area to Attainment for Ozone | Proposed Rule | On July 14, 2010, the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC), Air Pollution Control Division, submitted a request to redesignate the Knoxville 8- hour ozone nonattainment area to attainment for the 1997 8-hour National Ambient Air Quality Standards (NAAQS); and to approve a State Implementation Plan (SIP) revision containing a maintenance plan for the Knoxville, Tennessee Area. The Knoxville 1997 8-hour ozone nonattainment area is comprised of Anderson, Blount, Jefferson, Knox, Loudon, and Sevier Counties in their entireties, and the portion of Cocke County that falls within the boundary of the Great Smoky Mountains National Park (hereafter referred to as the "Knoxville Area"). In this action, EPA is proposing to approve the July 14, 2010, 8-hour ozone redesignation request for the Knoxville Area. Additionally, EPA is proposing to approve the 1997 8-hour ozone NAAQS maintenance plan for the Knoxville Area, including the 2007 baseline emission inventory, and the motor vehicle emission budgets (MVEBs) for nitrogen oxides (NO<INF>X</INF>) and volatile organic compounds (VOC) for 2024 for the Knoxville Area. This proposed approval of Tennessee's redesignation request is based on EPA's determination that the Knoxville Area has met the criteria for redesignation to attainment specified in the Clean Air Act (CAA), including the determination that the Knoxville 8-hour ozone nonattainment area has attained the 1997 8- hour ozone NAAQS. In this action, EPA is also describing the status of its transportation conformity adequacy determination for the new 2024 MVEBs that are contained in the 1997 8-hour ozone NAAQS maintenance plan for the Knoxville Area. This action is being taken pursuant to the CAA and its implementing regulations. | 2010-10-07 | 2010 | 10 | https://www.federalregister.gov/documents/2010/10/07/2010-25291/approval-and-promulgation-of-implementation-plans-and-designation-of-areas-for-air-quality-planning | https://www.govinfo.gov/content/pkg/FR-2010-10-07/pdf/2010-25291.pdf | Environmental Protection Agency | 145 | On July 14, 2010, the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC), Air Pollution Control Division, submitted a request to redesignate the Knoxville 8- hour ozone nonattainment area to attainment for the... |
