Surface Casing Program Has Transferred to the Railroad Commission
Article 2 of House Bill 2694, 82nd Texas Legislature, transferred from the Texas Commission on Environmental Quality (TCEQ) to the Railroad Commission of Texas (RRC) duties relating to the protection of groundwater resources from oil- and gas-associated activities. (Official announcement)
What does this transfer affect?
Specifically, Article 2 transferred from the TCEQ to the RRC, effective September 1, 2011, duties pertaining to the responsibility of preparing groundwater protection advisory/recommendation letters.
The RRC is now responsible for providing surface casing and groundwater protection recommendations for these activities:
- Exploration, development, or production of oil and gas resources—new drilling, other drilling activities including, but not limited to, enhanced recovery injection wells, injection wells for brine mining, injection wells for underground storage of hydrocarbons, seismic exploration and cathodic protection wells, well integrity tests, plugging of abandoned wells, core holes, and microseismic boreholes;
- Subsurface disposal and injection of oil and gas waste—saltwater disposal wells; and
- Anthropogenic carbon dioxide injection wells and geologic storage facilities under the RRC's jurisdiction.
Is this transfer complete?
Yes. Our Surface Casing Program and staff have already transferred to the RRC. The RRC’s Surface Casing Program (Groundwater Advisory Unit) is located in the William B. Travis Building, 1701 North Congress, Austin 78701.
