Utah Underground Injection Control Program; Class VI Primacy

Proposed rule; notice of public hearing.

The U.S. Environmental Protection Agency (EPA or Agency) has received a complete Underground Injection Control (UIC) program revision application from the State of Utah, requesting primary enforcement responsibility (primacy) for Class VI injection wells under Safe Drinking Water Act (SDWA) section 1422. The EPA's approval of the State's UIC program revision application would allow the Utah Department of Natural Resources, Division of Oil, Gas and Mining (DOGM) to issue and enforce compliance with UIC Class VI permits for injection wells used for geologic carbon sequestration. In this action, the EPA proposes to approve Utah's application to implement the UIC program for Class VI injection wells located within the State, except those on Indian lands for which the EPA retains primacy. The EPA has determined that Utah's UIC Class VI program meets Federal requirements for primacy under SDWA section 1422 and the applicable implementing regulations in 40 CFR parts 144, 145, and 146.
