## Abstract

Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is approving portions of Oklahoma's State Implementation Plan (SIP) submittal, that addresses a CAA requirement that SIPs account for potential interstate transport of air pollution that significantly contributes to nonattainment or interferes with maintenance of the 2012 fine particulate matter (PM<INF>2.5</INF>) National Ambient Air Quality Standards (NAAQS) in other states. EPA finds that emissions from Oklahoma 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.
