## Abstract

The Environmental Protection Agency (EPA) is taking final action to approve portions of the State Implementation Plan (SIP) submission, submitted by the State of North Carolina, through the Department of Environmental Quality (DEQ), on December 4, 2015, for inclusion into the North Carolina SIP, to demonstrate that the State meets 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." DEQ certified that the North Carolina SIP contains provisions that ensure the 2012 Annual PM<INF>2.5</INF> NAAQS is implemented, enforced, and maintained in North Carolina. EPA has determined that portions of North Carolina's SIP satisfies certain required infrastructure elements for the 2012 Annual PM<INF>2.5</INF> NAAQS.
