Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is proposing to approve revisions to the Texas State Implementation Plan (SIP). The revisions were submitted by the Texas Commission on Environmental Quality (TCEQ) on May 12, 2020, and May 13, 2020, and address certain CAA requirements for the Dallas-Fort Worth (DFW) Serious Nonattainment Area (NAA) for the 2008 ozone National Ambient Air Quality Standard (NAAQS). Specifically, EPA is proposing to approve the revisions to 30 Texas Administrative Code (TAC) Chapter 117 to implement the major source Reasonably Available Control Technology (RACT) requirement for Nitrogen Oxides (NO<INF>X</INF>), as addressed in the NO<INF>X</INF> RACT analysis and negative declaration included with the Serious area Attainment Demonstration (AD) SIP revision. The volatile organic compounds (VOC) portion of the RACT analysis in the Serious area AD submittal is addressed in a separate action.
