Finding of Failure To Submit a Clean Air Act Section 110 State Implementation Plan for Interstate Transport for the 2015 Ozone National Ambient Air Quality Standards (NAAQS)

The Environmental Protection Agency (EPA) is taking final action, finding that the State of Alabama failed to submit a complete infrastructure State Implementation Plan (SIP) revision to satisfy certain interstate transport requirements of the Clean Air Act (CAA or Act) with respect to the 2015 8-hour ozone national ambient air quality standards (NAAQS). Specifically, these requirements pertain to prohibiting significant contribution to nonattainment, or interference with maintenance, of the 2015 8-hour ozone NAAQS in other states. This finding of failure to submit a complete revision establishes a 2-year deadline for EPA to promulgate a Federal Implementation Plan (FIP) to address these interstate transport requirements for Alabama unless, prior to EPA promulgating a FIP, Alabama submits, and EPA approves, a SIP that meets these requirements.
