The U.S. Environmental Protection Agency (EPA) is taking direct final action to approve the State of Tennessee Underground Injection Control (UIC) Program for primacy to implement and enforce state regulations for all UIC injection wells located within the state, except for Class VI and all wells on Indian lands, as required by rule under the Safe Drinking Water Act (SDWA). The Agency determined that the state's UIC Program is consistent with the provisions of the SDWA and is as stringent as all applicable federal regulations to prevent underground injection activities that endanger underground sources of drinking water.
