## Abstract

The Environmental Protection Agency (EPA) is disapproving the portion of a Texas 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 Standard (NAAQS) in other states. Disapproval establishes a 2-year deadline for the EPA to promulgate a Federal Implementation Plan (FIP) for Texas to address the Clean Air Act (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 Texas.
