Dallas-Fort Worth (DFW) Attainment Demonstration and Reasonable Further Progress State Implementation Plan (SIP) Revisions for the 1997 Eight-Hour Ozone Standard

On December 7, 2011, the commission adopted two SIP revisions for the DFW 1997 eight-hour ozone standard nonattainment area:

• Dallas-Fort Worth Attainment Demonstration State Implementation Plan Revision for the 1997 Eight-Hour Ozone Standard (2010-022-SIP-NR)
• Associated Rule Revisions
• Dallas-Fort Worth Reasonable Further Progress State Implementation Plan Revision for the 1997 Eight-Hour Ozone Standard (2010-023-SIP-NR)

Dallas-Fort Worth Attainment Demonstration State Implementation Plan Revision for the 1997 Eight-Hour Ozone Standard (2010-022-SIP-NR)

The DFW attainment demonstration SIP revision provides photochemical modeling and weight of evidence analyses to demonstrate that the DFW nine-county nonattainment area will attain the 1997 eight-hour ozone standard by the June 15, 2013, attainment deadline. The attainment demonstration SIP revision includes a reasonably available control technology (RACT) analysis, a reasonably available control measures analysis, a motor vehicle emissions budget (MVEB) for 2012, and a contingency plan. Concurrent with this SIP revision, the commission adopted revisions to 30 Texas Administrative Code Chapter 115 into the Texas SIP.

Dallas-Fort Worth Reasonable Further Progress State Implementation Plan Revision for the 1997 Eight-Hour Ozone Standard (2010-023-SIP-NR)

The DFW reasonable further progress (RFP) SIP revision provides analyses of incremental reductions in ozone precursors (nitrogen oxides and VOC) from a 2002 base year out to attainment of the 1997 eight-hour ozone standard as well as updated emissions inventories and MVEBs for the 2011 and 2012 milestone years.

Eight-Hour Ozone SIP Revision Stakeholder Group for the DFW Area

A meeting of the Eight-Hour Ozone SIP Revision Stakeholder Group for the DFW Area was held on June 24, 2010, in Arlington. The DFW Eight-Hour Ozone SIP Stakeholder Group is an open-participation group that will meet periodically to discuss issues related to the DFW Eight-Hour Ozone SIP revision.
