## Abstract

The Environmental Protection Agency (EPA) is approving a revision to the North Carolina SIP, submitted by the North Carolina Department of Environmental Quality (NC DEQ) on March 24, 2016, and the portions of a revision to the Alabama State Implementation Plan (SIP), submitted by the Alabama Department of Environmental Management (ADEM) on December 9, 2015, addressing the Clean Air Act (CAA or Act) interstate transport (prongs 1 and 2) infrastructure SIP requirements for the 2010 1-hour 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, commonly referred to as an "infrastructure SIP." Specifically, EPA is approving North Carolina's March 24, 2016, SIP submission and the portions of Alabama's December 9, 2015, SIP submission addressing interstate transport requirements for the 2010 NO<INF>2</INF> NAAQS.
