2021-05436. State of Michigan Underground Injection Control (UIC) Class II Program; Primacy Approval

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

The U.S. Environmental Protection Agency (EPA or Agency) is proposing to approve the State of Michigan's Underground Injection Control Class II (UIC) Program for primacy. EPA determined that the State's program is consistent with the provisions of the Safe Drinking Water Act (SDWA) at Section 1425 to prevent underground injection activities that endanger underground sources of drinking water. The Agency's approval allows Michigan to implement and enforce its state regulations for UIC Class II injection wells located within the State. Michigan's authority excludes the regulation of injection well Classes I, III, IV, V and VI, and all wells in Indian country, as required by rule under the SDWA. The Agency 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 on the direct final rule, EPA will not take further action on this proposed rule.

DATES:

Written comments must be received by April 19, 2021.

II. The Proposed Rule

EPA proposes to approve Michigan's UIC Program primacy application for Class II injection wells located within the State (except all wells in Indian country), because it meets all requirements under SDWA for such programs. The proposed rule would grant Michigan primary enforcement authority to prevent Class II (oil and gas-related) 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 injection well Classes I, III, IV, V and VI, and for all wells in Indian country.

EPA has published a direct final rule in the “Rules and Regulations” section of the Federal Register, approving the State's program because EPA views this approval as noncontroversial and anticipates no adverse comment. For the Agency's rationale for approval and additional supplementary information, please see the preamble to the direct final rule. If EPA receives no adverse comment on the direct final rule, the Agency will not take further action on this proposed rule. If EPA receives adverse comment on the direct final rule, the Agency will withdraw the direct final rule and it will not take effect. The Agency would then consider and 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. Any parties interested in commenting must do so at this time.
