## Abstract

EPA is taking final action to approve the state implementation plan (SIP) revision submitted by the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC), to demonstrate that the State meets the requirements of sections 110(a)(1) and (2) with respect to sections 110(a)(2)(C) and (J), of the Clean Air Act (CAA or Act) for the 1997 8-hour ozone national ambient air quality standards (NAAQS). Section 110(a) of the CAA requires that each state adopt and submit a state implementation plan (SIP) for the implementation, maintenance, and enforcement of each NAAQS promulgated by EPA, which is commonly referred to as an "infrastructure" SIP. TDEC certified that the Tennessee SIP contains provisions that ensure the 1997 8-hour ozone NAAQS are implemented, enforced, and maintained in Tennessee (hereafter referred to as "infrastructure submission"). Tennessee's infrastructure submission, provided to EPA on December 14, 2007, and clarified in a subsequent May 28, 2009, submission, addressed the required infrastructure elements for the 1997 8-hour ozone NAAQS, however the subject of this notice is limited to infrastructure elements 110(a)(2)(C) and (J). All other applicable Tennessee infrastructure elements will be addressed in a separate rulemaking.
