Air Plan Approval; Alaska; Interstate Transport Requirements for the 2012 PM2.5

The Clean Air Act requires each State Implementation Plan (SIP) to contain adequate provisions prohibiting emissions that will have certain adverse air quality effects in other states. On March 10, 2016, the State of Alaska made a submission to the Environmental Protection Agency (EPA) to address these requirements. The EPA is approving the submission as meeting the requirement that each SIP contain adequate provisions to prohibit emissions that will contribute significantly to nonattainment or interfere with maintenance of the 2012 annual fine particulate matter (PM2.5) National Ambient Air Quality Standard (NAAQS).
