State of Tennessee Underground Injection Control (UIC) Program; Primacy Approval

The U.S. Environmental Protection Agency (EPA) proposes 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 wells and all wells on Indian lands, as required by rule under the Safe Drinking Water Act (SDWA). The Agency determined that the state's 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. EPA requests public comment on this proposed rule and supporting documentation. In the ``Rules and Regulations'' section of this Federal Register, the Agency published EPA's approval of the state's program as a direct final rule without a prior proposed rule. If the Agency receives no adverse comment, EPA will not take further action on this proposed rule.
