Pursuant to the Federal Clean Air Act (CAA or Act), the Environmental Protection Agency (EPA) is proposing to conditionally approve revisions to the Texas State Implementation Plan (SIP) addressing Oxides of Nitrogen (NO<INF>X</INF>) Reasonably Available Control Technology (RACT) for the Martin Marietta (formerly, Texas Industries, Inc., or TXI) cement manufacturing plant in Ellis County. We are proposing to fully approve revisions to the Texas SIP addressing NO<INF>X</INF> RACT for all other affected sources in the ten county Dallas Fort Worth (DFW) 2008 8-Hour ozone nonattainment area. We are also proposing to approve NO<INF>X</INF> RACT negative declarations (a finding that there are no emission sources in certain categories) for the DFW 2008 8-Hour ozone nonattainment area. The DFW 2008 8-Hour ozone nonattainment area consists of Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Rockwall, Tarrant, and Wise counties. The RACT requirements apply to major sources of NO<INF>X</INF> in these ten counties.
