Finding of Failure To Submit Section 110 State Implementation Plans for Interstate Transport for the 2006 National Ambient Air Quality Standards for Fine Particulate Matter

In this action, EPA is finding that Tennessee has failed to submit a State Implementation Plan (SIP) to satisfy the requirements of the Clean Air Act (CAA) with respect to the 2006 24-hour National Ambient Air Quality Standards (NAAQS) for fine particulate matter (24- hour PM<INF>2.5</INF>). Although Tennessee has submitted a SIP to address the requirements, the state subsequently withdrew that portion of its SIP submittal because it relied on the Clean Air Interstate Rule to address transport. This finding creates a 2-year deadline for the promulgation of a Federal Implementation Plan (FIP) by EPA. In a separate action, commonly referred to as the Transport Rule, EPA is finalizing a FIP for Tennessee to address these requirements.
