The EPA is approving a State Implementation Plan (SIP) revision which includes Agreed Orders with major airlines and Memoranda of Agreement (MOA) requiring owners and operators at major airports in the DFW area to implement reductions in oxides of nitrogen (NO<INF>X</INF>) emissions from Ground Support Equipment (GSE). The EPA is also approving a revised GSE emissions inventory for the DFW ozone nonattainment areas. These Agreed Orders and MOAs will contribute to attainment of the ozone standard in the DFW ozone nonattainment area. The EPA is approving these revisions to the Texas SIP to regulate emissions of NO<INF>X</INF> in accordance with the requirements of the Federal Clean Air Act (ACT).
