## Abstract

The Environmental Protection Agency (EPA) is taking final action on portions of the State Implementation Plan (SIP) submission, submitted by the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC), on March 13, 2014, to demonstrate that the State meets the infrastructure requirements of the Clean Air Act (CAA or Act) for the 2010 nitrogen dioxide (NO<INF>2</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 2010 NO<INF>2</INF> NAAQS is implemented, enforced, and maintained in Tennessee. EPA has determined that portions of Tennessee's infrastructure SIP submission, provided to EPA on March 13, 2014, satisfies the certain required infrastructure elements for the 2010 NO<INF>2</INF> NAAQS.
