The Environmental Protection Agency (EPA) is proposing to approve the State Implementation Plan (SIP) submission, provided by the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC), through a letter dated September 13, 2018, for inclusion into the Tennessee SIP. This proposal pertains to the infrastructure requirements of the Clean Air Act (CAA or Act) for the 2015 8-hour ozone national ambient air quality standard (NAAQS). Whenever EPA promulgates a new or revised NAAQS, the CAA requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each NAAQS promulgated by EPA. TDEC certified that the Tennessee SIP contains provisions that ensure the 2015 8-hour ozone NAAQS is implemented, enforced, and maintained in Tennessee. EPA is proposing to determine that portions of Tennessee's SIP submission satisfy certain required infrastructure elements for the 2015 8-hour ozone NAAQS.
