Approval and Promulgation of Implementation Plans; Louisiana; Interstate Transport Requirements for the 2012 PM2.5

Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is approving portions of Louisiana's State Implementation Plan (SIP) submittal and a technical supplement, that address 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 (PM2.5) National Ambient Air Quality Standards (NAAQS) in other states. EPA finds that emissions from Louisiana sources do not contribute significantly to nonattainment in, or interfere with maintenance by, any other state with regard to the 2012 PM2.5 NAAQS.
