          - 40 CFR Part 147
          - [EPA-HQ-OW-2011-0520; FRL-9924-91-OW]

# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Proposed rule.

# SUMMARY:

                        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.

Written comments must be received by May 6, 2015.

# SUPPLEMENTARY INFORMATION:

## Why is EPA issuing this proposed rule?

                    EPA proposes to approve the State of Tennessee's UIC Program primacy application for Class I, II, III, IV, and V injection wells located within the state (except all wells on Indian lands), as required by rule under the SDWA, to prevent underground injection activities that endanger underground sources of drinking water. Accordingly, the Agency proposes to codify the state's program in the                     *Code of Federal Regulations*                     (CFR) at 40 CFR part 147. EPA will continue to administer the UIC Program for Class VI wells and wells on Indian lands, if any such lands exist in the state in the future. The Agency has published a direct final rule in the “Rules and Regulations” section of today's                     **Federal Register**                    , approving the state's program because EPA views these actions as noncontroversial and anticipates no adverse comment. The Agency has provided reasons for the approval and additional supplementary information in the preamble to the direct final rule. If EPA receives no adverse comment, the Agency will not take further action on this proposed rule. If EPA receives adverse comment, the Agency will withdraw the direct final rule and it will not take effect. The Agency would then address all public comments in any subsequent final rule based on this proposed rule. The Agency does not intend to institute a second comment period on this action. Any parties interested in commenting must do so at this time. For further information, please contact the persons listed in the                     **FOR FURTHER INFORMATION CONTACT**                     section of this document.
