Summary

The Environmental Protection Agency (EPA) is proposing to approve the State Implementation Plan (SIP) submission, submitted by the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC), on December 16, 2015, for inclusion into the Tennessee SIP. This proposal pertains to the infrastructure requirements of the Clean Air Act (CAA or Act) for the 2012 Annual Fine Particulate Matter (PM<INF>2.5</INF>) national ambient air quality standard (NAAQS). The CAA requires that each state adopt and submit a SIP for the implementation, maintenance and enforcement of each NAAQS promulgated by EPA, which is commonly referred to as an "infrastructure SIP submission." TDEC certified that the Tennessee SIP contains provisions that ensure the 2012 Annual PM<INF>2.5</INF> NAAQS is implemented, enforced, and maintained in Tennessee. EPA is proposing to determine that portions of Tennessee's infrastructure SIP submission, provided to EPA on December 16, 2015, satisfy certain required infrastructure elements for the 2012 Annual PM<INF>2.5</INF> NAAQS.
