Summary of the SIP Revision

Adoption Date: 04/05/2000

EPA Approval Date: 04/26/01 (  66 FR 20931 )
Key Changes: The commission adopted revisions to Chapter 114 of 30 Texas Administrative Code (TAC) and the corresponding SIP in order to:

  • address U.S. Environmental Protection Agency concerns regarding the enforceability of the East Texas Regional Low Reid Vapor Pressure Gasoline program,
  • limit any increase in the use of methyl-tertiary-butyl-ether (MTBE) in gasoline to conform to the low RVP requirements, and
  • remove the state limits on sulfur content which have been supplanted by federal regulations found in Title 40 Code of Federal Regulations (CFR) Part 80, Subpart H (Gasoline Sulfur).

All parties in the gasoline distribution chain (producers, importers, terminals, pipelines, truckers, rail carriers, and retailers) will be required to maintain records of the transfer documents.

To conform with the requirements, gasoline producers and importers will be required to submit annual reports certifying that the use of MTBE in gasoline has not increased.

The rules will also require gasoline producers and importers to register with the TCEQ’s executive director.
