Approval and Promulgation of Implementation Plans and Designation of Areas for Air Quality Planning Purposes; State of Tennessee

الملخص

On November 14, 1994, the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC), submitted a maintenance plan and a request to redesignate the Middle Tennessee (Nashville) area from moderate nonattainment to attainment for ozone (O 3). Subsequently on August 9, 1995, and January 19, 1996, the State submitted supplementary information which included revised contingency measures and emission projections. The Nashville O 3 nonattainment area consists of Davidson, Rutherford, Sumner, Williamson, and Wilson Counties. Under the Clean Air Act (CAA), designations can be changed if sufficient data are available to warrant such changes. On June 24, 1996, EPA published a document proposing approval of the maintenance plan and redesignation request. EPA received a number of comments regarding the proposed rule. Those comments and the response thereto are summarized in the supplementary information that follows. In this action, EPA is approving the State of Tennessee's submittal because it meets the maintenance plan and redesignation requirements. The approved maintenance plan will become a federally enforceable part of Tennessee's State Implementation Plan
