## Abstract

The Environmental Protection Agency (EPA) is approving North Carolina's December 9, 2015, State Implementation Plan (SIP) submission pertaining to the Clean Air Act's (CAA or Act) "good neighbor" provision for the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS). The good neighbor provision requires each state's SIP to address the interstate transport of air pollution in amounts that contribute significantly to nonattainment, or interfere with maintenance, of a NAAQS in any other state. EPA concludes that North Carolina's SIP contains adequate provisions to prohibit emissions within the state from contributing significantly to nonattainment or interfering with maintenance of the 2008 8-hour ozone NAAQS in any other state.
