Texas Regulator Approves Expanded Underground Storage Permit for Gulf Coast Midstream Partners

AUSTIN, TX — The Railroad Commission of Texas (RRC) has issued a permit allowing Gulf Coast Midstream Partners, LLC (GCMP) to create, operate, and maintain an underground storage facility of up to five (5) underground storage caverns on the Nash Dome site in Fort Bend County, Texas.


The permit, approved by the RRC on July 20, 2026, authorizes the company to store liquid and gas hydrocarbons, as well as manage saltwater byproduct, within a total of five underground caverns. Each cavern can hold up to 14 to 16 million barrels of material.
The approval comes with a number of safety and monitoring requirements. The facility is managed under the oversight of the Commission's Oil and Gas Division, which is responsible for regulating oil, gas, and underground storage activities across the state. The RRC had previously approved the creation, operation and maintenance by GCMP of two (2) underground storage caverns on the site in June 2025. The expanded permit provides additional opportunity for increasing the reliability of natural gas pipelines serving Texas for decades to come.
