## Abstract

On June 28, 2010, the State of Idaho submitted a State Implementation Plan (SIP) revision to the Environmental Protection Agency (EPA) to address certain interstate transport requirements of the Clean Air Act (CAA). The EPA finds that the Idaho SIP meets the CAA interstate transport requirements that the SIP contain adequate provisions prohibiting air emissions that will contribute significantly to nonattainment or interfere with maintenance of the 2006 24-hour PM<INF>2.5</INF> NAAQS in any other state.
