The Environmental Protection Agency (EPA) is proposing to approve a portion of the state implementation plan (SIP) revision submitted by the District of Columbia (the District) that pertains to the good neighbor and interstate transport requirements of the Clean Air Act (CAA) for the 2008 ozone national ambient air quality standards (NAAQS). The CAA's good neighbor provision requires EPA and states to address the interstate transport of air pollution that affects the ability of other states \1\ to attain and maintain the NAAQS. Specifically, the good neighbor provision requires each state in its SIP to prohibit emissions that will significantly contribute to nonattainment, or interfere with maintenance, of a NAAQS in another state. The District has submitted a SIP revision that addresses the good neighbor provision for the 2008 ozone NAAQS. In this action, EPA is proposing to approve the District's SIP as having adequate provisions to meet the requirements of the good neighbor provision for the 2008 ozone NAAQS in accordance with section 110 of the CAA. ---------------------------------------------------------------------------
