Abstract
EPA is taking final action to disapprove a portion of a State Implementation Plan (SIP) submission from the State of Utah that is intended to demonstrate that its SIP meets certain interstate transport requirements of the Clean Air Act ("Act" or "CAA") for the 2006 fine particulate matter ("PM<INF>2.5</INF>") National Ambient Air Quality Standards (NAAQS). Specifically, EPA is disapproving the portion of the Utah SIP submission that addresses the CAA requirement prohibiting emissions from Utah sources from significantly contributing to nonattainment of the 2006 PM<INF>2.5</INF> NAAQS in any other state or interfering with maintenance of the 2006 PM<INF>2.5</INF> NAAQS by any other state. Under a recent court decision, this disapproval does not trigger an obligation for EPA to promulgate a Federal Implementation Plan (FIP) to address these interstate transport requirements.
