    EPA is announcing the establishment of a Federal Underground Injection Control (UIC) Class VI Program for Carbon Dioxide (CO2) Geologic Sequestration (GS) Wells under which EPA will directly implement the Class VI program nationally as of September 7, 2011. As of this date, states and owners or operators must submit all permit applications to the appropriate EPA Region in order for a Class VI permit to be issued per the Federal Requirements under the Underground Injection Control (UIC) Program for Carbon Dioxide (CO2) Geologic Sequestration (GS) Wells final rule of December 10, 2010. Direct implementation of the final Class VI requirements is in effect until such time as a State-submitted primary enforcement responsibility (primacy) application is approved by EPA. For additional information, please see the Federal Register notice and the final Class VI Rule.
