SIP Revision: Austin, San Antonio, and Northeast Texas EACs

A revision to the Texas SIP involving the Early Action Compact areas in Texas.

On November 17, 2004, the Commission adopted revisions to the State Implementation Plan (SIP) for the Austin, San Antonio, and Northeast Texas Early Action Compact (EAC) areas and Chapters 114 and 115 of Title 30 of the Texas Administrative Code (TAC). These documents are available for download on this Web page.


Summary of Revisions

At the TCEQ Commissioners’ Work Session on April 30, 2004, the commissioners discussed possible revisions to the SIP and several potential rule revisions requested by the EAC areas. The Commission decided to revisit these items at the July 14, 2004 Commissioners’ Agenda.

On July 14, 2004, the Commission proposed these recommended revisions including EAC attainment demonstrations for Austin, San Antonio, and Northeast Texas, and, at the request of the Austin and San Antonio areas, rule changes to 30 TAC 114—115.

This section provides a brief summary of the changes associated with each SIP revision and rule change.

  • Austin EAC SIP Revision: The adopted revision to the SIP consists of an 8-hour ozone attainment demonstration for the area based on the local plan submitted to TCEQ by the area in March 2004, under its EAC. This revision contains results of photochemical modeling and technical documentation in support of the attainment demonstration. As a result of these analyses, and at the request of the Austin-area local governments, the revision includes rule revisions implementing a vehicle inspection and maintenance (I/M) program in Travis and Williamson counties, a new rule allowing jurisdictions to enforce heavy duty diesel idling restrictions within their boundaries through an enforcement agreement with TCEQ, and for all five counties revisions to the VOC rules for degreasing, Stage 1 vapor recovery, and cutback-asphalt use.
  • San Antonio EAC SIP Revision: The adopted revision to the SIP consists of an eight-hour ozone attainment demonstration for the area based on the local plan submitted to TCEQ by the area in March 2004, under its EAC. This revision contains results of photochemical modeling and technical documentation in support of the attainment demonstration. As a result of these analyses, and at the request of the San Antonio local governments, the revision includes, for all four counties, revisions to the VOC rules for degreasing and Stage 1 vapor recovery.
  • Northeast Texas EAC SIP Revision: The adopted revision to the SIP consists of an 8-hour ozone attainment demonstration for the area based on the local plan submitted to TCEQ by the area in March 2004, under its EAC. This revision contains results of photochemical modeling and technical documentation in support of the attainment demonstration.
  • Vehicle Inspection and Maintenance (I/M): The adopted rulemaking would require all 2–24-year-old gasoline vehicles in Travis and Williamson Counties to undergo an annual emissions inspection test along with the current annual safety inspection. The program would be similar to the I/M program currently operated in other areas of the state.
  • Heavy-Duty Diesel Idling Opt-in: The adopted rulemaking would allow local governmental entities to enforce restrictions on heavy-duty diesel idling within their jurisdictions if they sign an enforcement agreement with TCEQ.
  • VOC Measures: The adopted rulemaking would revise 30 TAC Chapter 115, Subchapters C, E and F, to implement VOC controls on degreasing units, require the use of Stage 1 Vapor Recovery equipment in gasoline stations with more than 25,000 gallons per month of throughput, and prohibit the seasonal use of cutback asphalt. Degreasing and Stage 1 Vapor recovery changes will be applicable to the five Austin-area counties and the four San Antonio EAC counties, while cutback asphalt restrictions will only be applicable in the Austin area.
