Last week, the U.S. Environmental Protection Agency (EPA) announced that it will formally grant the Railroad Commission of Texas (RRC) primary authority (known as “primacy”) to administer the Class VI Underground Injection Control (UIC) program for the geologic sequestration of carbon dioxide under the Safe Drinking Water Act. With this approval, developers pursuing carbon capture and storage (CCS) projects in Texas will work directly with the RRC for Class VI well permitting, rather than navigating the EPA’s permit queue.
