## Abstract

EPA is announcing the establishment of a Federal Underground Injection Control (UIC) Class VI Program for Carbon Dioxide (CO<INF>2</INF>) Geologic Sequestration (GS) Wells under which EPA will directly implement the Class VI Program nationally as of September 7, 2011. States and potential owners or operators of CO<INF>2</INF> GS wells must submit all permit applications to the appropriate EPA Region in order for a Class VI permit to be issued pursuant to the Federal Requirements under the Class VI rule finalized on December 10, 2010. Direct Federal 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.
