Findings of Failure To Submit a Section 110 State Implementation Plan for Interstate Transport for the 2008 National Ambient Air Quality Standards for Ozone

The Environmental Protection Agency (EPA) is taking final action finding that 24 states have failed to submit infrastructure State Implementation Plans (SIPs) to satisfy certain interstate transport requirements of the Clean Air Act (CAA) with respect to the 2008 8-hour ozone national ambient air quality standard (NAAQS). Specifically, these requirements pertain to significant contribution to nonattainment, or interference with maintenance, of the 2008 8-hour ozone NAAQS in other states. These findings of failure to submit establish a 2-year deadline for the EPA to promulgate a Federal Implementation Plan (FIP) to address the interstate transport SIP requirements pertaining to significant contribution to nonattainment and interference with maintenance unless, prior to the EPA promulgating a FIP, the state submits, and the EPA approves, a SIP that meets these requirements.
