          - 40 CFR Part 147
          - [EPA-HQ-OW-2017-0584; FRL-9970-73-OW]

# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Proposed rule.

# SUMMARY:

                        The Environmental Protection Agency (EPA) is providing notice of the transfer of the state of Idaho's Underground Injection Control (UIC) program for Class II injection wells from Idaho to EPA, and is concurrently issuing a proposed rule to amend EPA's UIC regulations to reflect such transfer. This transfer would be effective upon publication in the                         **Federal Register**                         of a final rule revising such regulations. Idaho submitted a formal request that EPA transfer and directly implement the Class II UIC Program. Idaho would maintain primacy for Class I, III, IV, and V injection wells pursuant to their EPA-approved program in 1985.

# SUPPLEMENTARY INFORMATION:

## I. Why is EPA taking this action?

On August 25, 2017, EPA received a letter from the Idaho Department of Water Resources (IDWR), formally requesting that EPA transfer and directly implement the Class II UIC program in Idaho, pursuant to 40 CFR 145.34(a). Class II injection wells inject fluids (1) that are brought to the surface in connection with natural gas storage, or oil or natural gas production; or (2) for the purpose of enhanced oil or natural gas recovery; or (3) for the storage of hydrocarbons, which are liquid at standard temperature and pressure. Idaho received primary implementation and enforcement authority (primacy) for Class I, II, III, IV, and V injection wells under the Safe Drinking Water Act, section 1422, on July 22, 1985. Idaho has since maintained primacy for these injection well classes in Idaho, including Class II.

Class II injection wells were banned in Idaho under the state's regulations in 1985, when EPA originally approved Idaho primacy, and as a result, this ban was codified in EPA's regulations. However, in 2013, the state passed legislation which allows these wells. Although the state's regulations now allow Class II wells, Idaho has not issued any Class II permits because EPA has not approved the change to Idaho's approved Class II UIC program and the wells remain banned under federal law; therefore, the state is not authorized to issue Class II permits. The voluntary transfer of authority for the UIC Class II program to EPA would allow EPA to issue Class II permits in Idaho. EPA would be responsible for the direct implementation of the Class II underground injection program in Idaho, including permitting, compliance, and enforcement responsibilities, pursuant to the SDWA and federal UIC regulations.

                    This                     **Federal Register**                     document constitutes public notice of the transfer of Idaho's Class II program to EPA, as required by 40 CFR 145.34(a)(3). In this                     **Federal Register**                     document, EPA also proposes to make conforming changes to its regulations to reflect such transfer. 40 CFR part 147 sets forth the applicable UIC programs for each of the states. This rule would update 40 CFR part 147, subpart N, which currently lists Idaho as having primacy over Class II, to indicate that EPA will directly implement the Class II UIC program in Idaho. This transfer of authority will be effective upon publication of the final rule, revising such regulations, in the                     **Federal Register**                    . Because the transfer and rulemaking will allow wells to be permitted that were previously banned, EPA finds that there is “good cause” to make this rule, when final, effective upon publication in the                     **Federal Register**                    . 5 U.S.C. 553(d)(1) and (3).                

## II. Legal Authorities

                    A state with an approved primacy program may voluntarily transfer UIC program responsibilities to EPA, pursuant to 40 CFR 145.34(a). The regulations require that EPA provide notice of such transfer in the                     **Federal Register**                     at least 30 days before the transfer is to occur. 40 CFR 145.34(a)(3). The regulations do not provide for opportunity to comment on whether to transfer, and accordingly, EPA is not taking comment on such transfer.                

EPA's regulations at 40 CFR part 147 set forth the applicable UIC programs for each of the states. This rule would make ministerial revisions to these regulations to reflect the transfer noticed herein. Specifically, the rule would revise 40 CFR part 147, subpart N, to indicate that the Class II UIC program for Idaho is to be directly implemented by EPA, and consists of the UIC program requirements of 40 CFR parts 124, 144, 146, and 148. EPA is taking comment only on these revisions.

## III. Statutory and Executive Order Reviews

### A. Executive Order 12866: Regulatory Planning and Review and Executive Order 13563: Improving Regulation and Regulatory Review

This action is not a significant regulatory action and was therefore not submitted to the Office of Management and Budget (OMB) for review.

### B. Executive Order 13771: Reducing Regulations and Controlling Regulatory Costs

This action is not expected to be an Executive Order 13771 regulatory action because this action is not significant under Executive Order 12866.

### C. Paperwork Reduction Act (PRA)

This action does not impose any new information collection burden under the PRA. OMB has previously approved the information collection activities contained in the existing regulations and has assigned OMB control number 2040-0042.

### D. Regulatory Flexibility Act (RFA)

I certify that this action will not have a significant economic impact on a substantial number of small entities under the RFA. In making this determination, the impact of concern is any significant adverse economic impact on small entities. An agency may certify that a rule will not have a significant economic impact on a substantial number of small entities if the rule relieves regulatory burden, has no net burden or otherwise has a positive economic effect on the small entities subject to the rule. This rule does not impose any requirements on small entities; this action withdraws a state program and therein transfers direct implementation of the Class II UIC program to EPA. We have therefore concluded that this action will have no net regulatory burden for any directly regulated small entities.

### E. Unfunded Mandates Reform Act (UMRA)

This action does not contain any unfunded mandate as described in UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect small governments. This rule does not impose any mandates on small entities; this action withdraws a state program and therein transfers direct implementation of the Class II UIC program to EPA.

### F. Executive Order 13132: Federalism

                    This action does not have federalism implications. It will not have substantial direct effects on the states, on the                           ( print page 55970)                        relationship between the national government and the states, or on the distribution of power and responsibilities among the various levels of government. This action contains no federal mandates for state and local governments and does not impose any enforceable duties on state and local governments. This action merely withdraws a state program (at the voluntary request from Idaho) and therein transfers implementation of the Class II UIC program to EPA.                

### G. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments

This action does not have tribal implications as specified in Executive Order 13175. This action contains no federal mandates for tribal governments and does not impose any enforceable duties on tribal governments. Thus, Executive Order 13175 does not apply to this action.

### H. Executive Order 13045: Protection of Children From Environmental Health and Safety Risks

The EPA interprets Executive Order 13045 as applying only to those regulatory actions that concern environmental health or safety risks that the EPA has reason to believe may disproportionately affect children, per the definition of “covered regulatory action” in section 2-202 of the Executive Order. This action is not subject to Executive Order 13045 because it transfers a state program.

### I. Executive Order 13211: Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use

This action is not subject to Executive Order 13211, because it is not a significant regulatory action under Executive Order 12866.

### J. National Technology Transfer and Advancement Act

This rulemaking does not involve technical standards.

### K. Executive Order 12898: Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Populations

The EPA has determined that this action is not subject to Executive Order 12898 (59 FR 7629, February 16, 1994) because it does not establish an environmental health or safety standard. This rule does not impose any health or safety standards; this action transfers a state program and therein transfers direct implementation of the Class II UIC program to EPA.

E. Scott Pruitt,

Administrator.

For the reasons set out in the preamble, Title 40 chapter 1 of the Code of Federal Regulations is proposed to be amended as follows:

# PART 147—STATE, TRIBAL, AND EPA-ADMINISTERED UNDERGROUND INJECTION CONTROL PROGRAMS

1. The authority citation for part 147 is revised to read as follows: 

Authority:42 U.S.C. 300h*et seq.;*                         and 42 U.S.C. 6901*et seq.*

# Subpart N—Idaho

2. Amend § 147.650 by revising the section heading and the introductory paragraph to read as follows: 

§ 147.650 

                        The UIC program for Class I, III, IV, and V wells in the state of Idaho, other than those on Indian lands, is the program administered by the Idaho Department of Water Resources, approved by EPA pursuant to section 1422 of the Safe Drinking Water Act. Notice of this approval was published in the                         **Federal Register**                         on June 7, 1985; the effective date of this program is July 22, 1985. This program consists of the following elements, as submitted to EPA in Idaho's program application. Note: because EPA subsequently transferred the Class II UIC program from the Idaho Department of Water Resources to EPA, references to Class II in the following elements are no longer relevant or applicable for federal UIC purposes.                    

* * * * *

3. Amend § 147.651 by revising the section heading and paragraphs (a) and (b) to read as follows: 

§ 147.651 

                        (a)                         *Contents.*                         EPA administers the UIC program for all classes of wells on Indian lands and for Class II wells on non-Indian lands in the state of Idaho. This program consists of the UIC program requirements of 40 CFR parts 124, 144, 146, 148, and any additional requirements set forth in the remainder of this subpart. Injection well owners and operators, and EPA shall comply with these requirements.                    

                        (b)                         *Effective dates.*                         The effective date of the UIC program for Indian lands in Idaho is June 11, 1984. The effective date of the UIC program for Class II wells on non-Indian lands in Idaho is [date of publication of final rule in the                         **Federal Register**                        ].
