On November 12, 2025, the U.S. Environmental Protection Agency (EPA) approved Texas’s request for primacy over Class VI underground injection control (UIC) wells under the Safe Drinking Water Act, authorizing the Railroad Commission of Texas (RRC) to issue and oversee permits for carbon capture and storage (CCS) injection projects. The final rule makes Texas the sixth state to secure primacy over Class VI wells—following North Dakota, Wyoming, Louisiana, Arizona and West Virginia—and marks EPA’s third such approval in the last several months.
