The Environmental Protection Agency (EPA) is approving state implementation plan (SIP) revisions submitted by the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC), through letters dated February 26, 2020. Specifically, EPA is approving the removal of Tennessee's motor vehicle inspection and maintenance (I/M) program requirements for Davidson, Sumner, Rutherford, Williamson and Wilson Counties in Tennessee (also known as the Middle Tennessee Area) and Hamilton County (also known as the Chattanooga Area), from the federally-approved SIP. EPA is approving the February 26, 2020, SIP revisions to remove the I/M program requirements for the aforementioned areas from the federally- approved SIP because Tennessee's requests are consistent with the Clean Air Act (CAA or Act) and applicable regulations.
