The same source also states
Tenn. Code Ann. section 68-201-119(c) allows Tennessee counties to retain local I/M programs under certain conditions. As Tennessee is requesting removal of the I/M program from the SIP, EPA's analysis in this final rule assumes that no I/M program will be implemented in Hamilton County or the Middle Tennessee Area. However, this final action does not preclude local I/M programs from being retained at a local level outside of the SIP.
