The Environmental Protection Agency (EPA or Agency) is hereby approving an application from the State of Wyoming under the Safe Drinking Water Act (SDWA) to implement an underground injection control (UIC) program for Class VI injection wells to protect underground sources of drinking water located within the state, except within Indian lands. EPA will continue to administer all well classes within Indian lands. Class VI wells are used for the underground injection of carbon dioxide into deep subsurface rock formations for long-term storage.
