Abstract
Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is approving portions of the Arkansas State Implementation Plan (SIP) submittal addressing the CAA requirement that SIPs address the potential for interstate transport of air pollution to significantly contribute to nonattainment or interfere with maintenance of the 2012 fine particulate matter (PM<INF>2.5</INF>) National Ambient Air Quality Standard (NAAQS) in other states. EPA finds that emissions from Arkansas sources do not contribute significantly to nonattainment in, or interfere with maintenance by, any other state with regard to the 2012 PM<INF>2.5</INF> NAAQS. The EPA is also approving a revision to update incorporation by reference of NAAQS germane to the Arkansas SIP.
