Texas Claims Control Over Carbon Storage

EPA hands Texas authority over Class VI wells, speeding carbon storage permits while keeping federal oversight intact

26 Feb 2026

Texas has redrawn the map for carbon storage in America. In a landmark move under the Safe Drinking Water Act, the US Environmental Protection Agency has granted the state primacy over Class VI Underground Injection Control wells, giving Texas regulators the power to approve permits for deep carbon dioxide storage.

The decision shifts authority from Washington to the Texas Railroad Commission, the state’s long-standing oil and gas regulator. Companies that want to inject carbon dioxide underground for permanent geologic storage will now work primarily with state officials rather than waiting in a federal queue.

That queue has been slow moving. Developers have often faced review timelines stretching two years or more, according to public records and industry groups, creating uncertainty around project financing and construction schedules. With primacy in state hands, companies expect faster reviews and a clearer path to claiming federal 45Q tax credits tied to carbon sequestration.

For investors, speed matters. Industry leaders say regulatory certainty can unlock private capital, especially along the Gulf Coast, where billions of dollars in proposed carbon capture and storage projects are clustered near refineries and petrochemical plants. Major players including ExxonMobil and Occidental have outlined plans for large-scale carbon transport and storage networks designed to serve heavy industry.

Texas brings more than ambition to the table. The state sits atop vast geologic storage formations and has decades of experience overseeing oil and gas injection wells under the UIC framework. Supporters argue that this technical foundation, combined with streamlined authority, positions Texas as a potential national hub for carbon management.

Federal oversight, however, remains firmly in place. The EPA will continue to review the state’s program and can revoke primacy if Texas fails to meet federal standards. Operators must still comply with strict rules governing well design, monitoring, and long-term site integrity to protect underground sources of drinking water.

The ripple effects extend well beyond state lines. As carbon capture becomes central to corporate climate strategies, permitting efficiency may determine where projects take root. Other states are now watching closely, weighing whether to seek similar authority and accelerate their own carbon storage ambitions.
