## Abstract

The Environmental Protection Agency (EPA) is disapproving the portion of a Louisiana State Implementation Plan (SIP) submittal pertaining to interstate transport of air pollution which will significantly contribute to nonattainment or interfere with maintenance of the 2008 ozone National Ambient Air Quality Standards (NAAQS) in other states. Disapproval will establish a 2-year deadline, under Clean Air Act (CAA) Section 110(c), for the EPA to promulgate a Federal Implementation Plan (FIP) for Louisiana to address the CAA interstate transport requirements pertaining to significant contribution to nonattainment and interference with maintenance of the 2008 ozone NAAQS in other states, unless the EPA approves a SIP that meets these requirements. Disapproval does not start a mandatory sanctions clock for Louisiana.
