The Environmental Protection Agency (EPA) is approving the remaining portion of a state implementation plan (SIP) revision submitted by the State of Nevada. This revision addresses the interstate transport requirements of the Clean Air Act (CAA) with respect to the 2010 1-hour sulfur dioxide (SO<INF>2</INF>) primary national ambient air quality standard (NAAQS). In this action, the EPA has determined that Nevada will not contribute significantly to nonattainment or interfere with maintenance of the 2010 1-hour SO<INF>2</INF> NAAQS in any other state.
