Alaska Underground Injection Control (UIC) Program; Class VI Primacy

The U.S. Environmental Protection Agency (EPA or the Agency) has received a complete Underground Injection Control (UIC) application from the State of Alaska, 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 primacy application would allow the Alaska Oil and Gas Conservation Commission (AOGCC) 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 Alaska's application to implement the UIC program for Class VI injection wells located within the State, except those located within Indian country and those located within areas of exclusive Federal jurisdiction.
