SUBJECT: STATUS OF THE DEVELOPMENT OF MEMORANDA OF

UNDERSTANDING WITH NEBRASKA AND WYOMING, REGARDING

THE REGULATION OF GROUNDWATER PROTECTION AT THEIR IN

SITU LEACH URANIUM RECOVERY FACILITIES

PURPOSE:

To inform the Commission about the status of the U.S. Nuclear Regulatory Commission (NRC)

staff’s actions to develop Memoranda of Understanding (MOUs) that would allow the States of

Nebraska and Wyoming to take lead responsibility for implementing regulation of groundwater

protection at in situ leach (ISL) uranium recovery facilities located in these States.

BACKGROUND:

For several years, the staff has been pursuing an initiative to eliminate or reduce the

overlapping regulation of groundwater protection provided by the NRC and the non-Agreement

States at operating ISL facilities. In this regard, the inefficiencies associated with overlapping

regulation are expected to increase, with the market price for “yellowcake” (uranium oxide,

U3O8) trending upwards in recent years. With this trend, uranium recovery licensees in both

Nebraska and Wyoming have indicated interest in submitting license amendment applications

for new satellite ISL facilities, within the next year.

The Commissioners - 2 -

In SECY-03-0186, the staff presented several options for reducing or eliminating the

overlapping regulation of groundwater protection at affected ISL facilities in non-Agreement

States. In that paper, the staff recommended allowing the non-Agreement States to take lead 

responsibility for active regulation of groundwater protection through the development of MOUs. 

In a Staff Requirements Memorandum dated November 19, 2003, the Commission approved

the staff’s recommendation and directed the staff to develop a Regulatory Issue Summary (RIS)

to inform the public about the proposal and proceed with the development of an MOU with each

State. 

RIS 2004-02 solicited public comment on the proposal to allow the non-Agreement States to

take lead responsibility for active regulation of groundwater protection at affected ISL facilities. 

Comments on the proposal were received from the States of New Mexico, Texas, and

Wyoming; the Wyoming Mining Association; the National Mining Association (NMA); the Nuclear

Energy Institute; Crow Butte Resources, Inc.; and Power Resources, Inc. All comments were

favorable and supported the NRC’s proposal through the development of MOUs with the

affected States. On June 7, 2004, the staff issued RIS 2004-09, to discuss the comments

received in response to RIS 2004-02 and to inform the public of the NRC’s continuing plans to

allow the non-Agreement States to take lead responsibility for active regulation of groundwater

protection in the affected States. RIS 2004-09 is provided as an Attachment to this paper.

In June 2004, the staff conducted a detailed evaluation of Nebraska’s U.S. Environmental

Protection Agency (EPA)-authorized Underground Injection Control (UIC) Program, using the

NRC’s groundwater protection program, as provided in NUREG-1569, “Standard Review Plan

for In Situ Leach Uranium Extraction License Applications ” (June 2003). In this regard, the

NRC’s groundwater protection program for ISL facilities is founded in the statutory requirements

set forth in the Uranium Mill Tailings Radiation Control Act of 1978 (UMTRCA). The staff

conducted a similar comparability review of Wyoming’s EPA-authorized UIC Program in August

2004. The purpose of these reviews was to compare the States’ groundwater protection

programs with the NRC’s groundwater protection program, to determine if the States’ programs

were at least equivalent to the NRC’s program. The staff planned to use a finding of

equivalency between the NRC and State groundwater protection programs as the basis for

allowing these States to take lead responsibility for active regulation in this area through the

development of MOUs. As more fully discussed below, the Nebraska and Wyoming

groundwater protection programs were found to be not equivalent to the NRC’s groundwater

protection program. 

DISCUSSION:

The processes involved in ISL mining of uranium from an underground ore zone chemically alter

the groundwater quality relative to the conditions that existed before the onset of operations. 

After the completion of uranium recovery in a particular mining area, licensees are required to

restore the affected groundwater to established standards to assure the protection of public

health, safety, and the environment. Because the most significant impact of ISL mining is the

chemical alteration of the groundwater in the ore zone of interest, the groundwater restoration

elements of the NRC’s groundwater protection program are the most important aspects of the

NRC’s program for ISL facilities. 

As noted above, the NRC’s groundwater protection program is grounded in the requirements of

UMTRCA. UMTRCA directed the EPA Administrator to promulgate generally applicable
The Commissioners - 3 -

standards for the protection of public health, safety, and the environment from radiological and

nonradiological hazards associated with the production, handling, and disposition of byproduct

material resulting from uranium recovery operations. UMTRCA further specified that such

generally applicable standards for nonradiological hazards “shall be consistent” with the

standards issued by the EPA under the Solid Waste Disposal Act (SWDA) for hazardous

wastes. EPA standards issued pursuant to the SWDA were provided in 40 CFR Part 264

(“Standards for Owners and Operators of Hazardous Waste Treatment, Storage, and Disposal

Facilities”). UMTRCA mandated that implementation and enforcement of the applicable EPA

standards for both radiological and nonradiological hazards associated with byproduct material

would be the NRC’s responsibility.

Pursuant to the requirements of UMTRCA, the EPA promulgated its health, safety, and

environmental standards for byproduct material in 40 CFR Part 192 (“Health and Environmental

Protection Standards for Uranium and Thorium Mill Tailings”). Subpart D of Part 192

establishes the standards for uranium byproduct materials, including groundwater protection

requirements in 40 CFR 192.32(a)(2), which specify that uranium byproduct materials shall be

managed in conformance with the groundwater protection standard in 40 CFR 264.92.

The requirements in 40 CFR 264.92 specify that hazardous constituents detected in

groundwater at a regulated unit (e.g., NRC-licensed uranium recovery facilities) must not

exceed the concentration limits provided in 40 CFR 264.94. The concentration limits in

40 CFR 264.94 are tiered, reflecting the underlying intent of the standards to prevent

groundwater degradation from hazardous constituents, but recognizing that some degree of

constituent contamination in the groundwater may be acceptable if those constituents do not

pose a substantial present nor potential hazard to human health or the environment. The

primary standard in the tiered set of standards in 40 CFR 264.94 limits the concentration of

hazardous constituents in the groundwater to background levels. In the application of this

standard to the NRC’s licensed ISL facilities, the licensees must first make significant efforts to

restore degraded groundwater from uranium recovery operations to background levels before

consideration of alternative levels (e.g., specified maximum concentration limits, alternative

concentration limits, or class-of-use concentration limits), based on technical, economic, health,

or environmental reasons. 

Although the underground mining zone is not byproduct material, it is part of the uranium

extraction process which the NRC regulates. The Commission has approved the guidance in

NUREG-1569 which is applied on a case-by-case basis to implement NRC regulation of

groundwater protection at ISL facilities. The NRC’s groundwater protection program for ISL

facilities is primarily embodied in NUREG-1569 which, per Commission direction, the staff

developed in lieu of a new 10 CFR Part 41 (“Domestic Licensing of Uranium and Thorium

Recovery Facilities”). The proposed Part 41 would have implemented EPA groundwater

protection standards for ISL facilities. Although those standards have not yet been embodied in

NRC regulations, NUREG-1569 is grounded in the statutory mandate discussed above. 

As described in NUREG-1569, the NRC’s groundwater protection program includes both

primary and secondary restoration standards. The primary goal of groundwater restoration is to

return the water quality within the exploited uranium production zone, and any affected aquifers,
The Commissioners - 4 -

to pre-operational (baseline) water quality conditions. Licensees must make significant efforts

to reach the primary restoration standards and must continue these efforts so long as

restoration continues to result in significant improvements in groundwater quality. However,

Section 84 of the Atomic Energy Act of 1954, as amended by UMTRCA, contemplates that the

primary standards may not be attainable because of site-specific conditions or economic costs

and secondary restoration standards are established at the time of licensing. The secondary

standards recognize that ISL operations may result in permanent changes to water quality (i.e.,

relative to baseline water quality) in the uranium production zone which leaves some constituent

concentrations higher than pre-operational baseline levels. Under these circumstances,

secondary restoration goals are intended to return the water quality to its pre-operational class

of use. The NRC standards for groundwater protection, in NUREG-1569, appropriately mirror

the standards set forth in the SWDA. To illustrate the difference between the primary and

secondary restoration standards, the Crow Butte Resources, Inc., ISL has a primary restoration

standard of 0.092 mg/l for uranium compared to a secondary restoration standard of 5 mg/l.

The staff’s June 2004 evaluation of Nebraska’s groundwater protection program identified a

major variance with respect to the groundwater restoration standards specified in Nebraska’s 

Environmental Protection Act and regulations for its UIC Program, as provided in the Nebraska

Administrative Code, Title 122, “Rules and Regulations for Underground Injections and Mineral

Production Wells.” In both the statute and the regulations, the Nebraska groundwater

restoration standard is specified to “....return each resource to a quality of use consistent with

the uses for which the resource was suitable prior to the activity.” In essence, the Nebraska

restoration standard is equivalent to the secondary restoration standards in the NRC’s

groundwater protection program. Thus, the most important element of Nebraska’s groundwater

protection program is not equivalent to the corresponding element in the NRC’s program.

The staff’s August 2004 evaluation of Wyoming’s groundwater protection program identified the

same variance in Wyoming’s Environmental Quality Act and Industrial Development and

Information Siting Act, and the rules that the Wyoming Department of Environmental Quality

(WDEQ) has proposed for implementation of its UIC Program. In the Wyoming statute,

groundwater restoration is defined as “....the condition achieved when the quality of all

groundwater affected by the injection of recovery fluids is returned to a quality of use equal to or

better than, and consistent with the uses for which the water was suitable prior to the operation

by employing the best practicable technology.” This restoration standard, like the Nebraska

standard, is essentially equivalent to the secondary restoration standards in the NRC’s

groundwater restoration program. Until fairly recently, the WDEQ implemented a restoration

standard for its UIC Program that was consistent with the NRC’s primary restoration standards. 

However, as a result of a challenge to the more stringent restoration standards in WDEQ’s

regulations, from the Wyoming Mining Association, in July 2003, the WDEQ proposed new rules

and regulations, in March 2004, to make the restoration standards consistent with the
The Commissioners - 5 -

standards established in the underlying statute. The staff understands that these new rules and 

regulations were promulgated in May 2005. Thus, the staff’s findings of a major variance in the

Wyoming groundwater restoration standards were similar to the findings in the 

Nebraska review.

The variance in Nebraska and Wyoming restoration standards would impact the NRC’s ability to

allow these States to take lead responsibility for active regulation of groundwater protection

through a transparent MOU process. The following areas of the NRC’s groundwater protection 

program would be impacted by the variance: (1) ISL site characterization; (2) pre-operational or

baseline water quality monitoring; (3) production or operational monitoring; and (4) the

groundwater restoration program, including proposed restoration methods, restoration

monitoring, and post-restoration stability monitoring. The staff’s comparability evaluation of the

Nebraska and Wyoming groundwater protection programs also identified additional, but

relatively minor, issues, in relation to well mechanical-integrity testing. However, the staff

believes that these issues could be easily resolved with minor changes or enhancements to the

States’ groundwater protection programs. In that vein, the following areas of the NRC’s

groundwater protection program could be deferred to the States through the MOU process: 

(1) ISL process methodology and equipment design, including ISL process instrumentation and

control; (2) well design; (3) well mechanical-integrity testing; and (4) well inspection. 

In a letter to Chairman Diaz dated May 9, 2005, the NMA requested information about the status

of the MOU development effort for Nebraska and Wyoming ISL facilities, suspecting that this

effort may have “hit a roadblock.” The NMA expressed interest in having its views heard prior to

any final decisions on the MOU development effort and provided its understanding of the

statutory requirements, and the guidance in NUREG-1569, for restoration of groundwater at ISL

facilities operating under EPA-authorized UIC Programs. In the June 2, 2005, response to

NMA, the staff stated their intent to meet with the NMA to discuss their concerns about the MOU

development effort. In a subsequent letter to Chairman Diaz dated June 13, 2005, the WDEQ

requested clarification of the NRC’s groundwater restoration standards in NUREG-1569. The

planned meeting with the NMA will also include representatives from the Nebraska and

Wyoming UIC Programs, and other stakeholders, to discuss the issues raised by both the NMA

and WDEQ, the significant variances identified in the Nebraska and Wyoming UIC Programs,

the related impediments they pose to the MOU development effort, and the corresponding

deferral of active regulation of groundwater protection to the States. After evaluating

stakeholder feedback from this meeting, the staff will develop and present options with a

recommendation for Commission consideration regarding the future direction of the MOU

development effort.

STATUS ON DEFERRAL OF ACTIVE REGULATION OF

GROUND-WATER PROTECTION AT IN SITU LEACH

URANIUM EXTRACTION FACILITIES

ADDRESSEES

All holders of materials licenses for uranium and thorium recovery facilities.

INTENT

The U.S. Nuclear Regulatory Commission (NRC) is issuing this regulatory issue summary (RIS)

to inform addressees and other interested parties of (1) the NRC’s plans for the deferral of

active regulation of ground-water protection at in situ leach (ISL) uranium extraction facilities;

and (2) the comments received in response to RIS 2004-02 on this topic. This RIS supersedes

RIS 2004-02 in its entirety. No specific action or written response is required.

BACKGROUND

Over the past several years, the uranium recovery industry has expressed concern that the

NRC regulation of ground-water at ISLs duplicates the ground-water protection programs

required by the Safe Drinking Water Act (SDWA), as administered by the U.S. Environmental

Protection Agency (EPA) or EPA-authorized States. EPA and the States protect ground-water

quality through the Underground Injection Control (UIC) program, under the SDWA. Some

EPA-authorized States require additional measures in their UIC programs that are more

stringent than the Federal program.

Historically, the NRC has imposed conditions on ISL operations to ensure that ground-water

quality is maintained during licensed activities and that actions are taken to ensure the

restoration of ground-water quality before the license is terminated. The specific conditions

imposed in ISL licenses have typically been the result of NRC’s independent review of sitespecific conditions at the ISLs, as documented in safety evaluation reports and appropriate

environmental evaluations. 

In addition to the NRC’s review, licensees must also obtain a UIC permit from EPA or the EPAauthorized State, before uranium recovery operations can begin. The EPA or the authorized

State conducts many of the same types of reviews as the NRC. This is illustrated by the NRC 

ML041540558
RIS 2004-09

Page 2 of 5

incorporating ground-water protection limits from a State’s permitting program into specific

license requirements, after conducting its own review of the licensee’s ground-water protection 

program, including the use of State-imposed standards. The staff routinely accepts specific

methodologies and guidance developed by the EPA or States for ground-water monitoring

programs and well construction. RIS 2000-23, “Recent Changes to Uranium Recovery Policy,”

dated November 30, 2000 (ML003773008) provides additional background information on this

topic.

Since the publication of RIS 2000-23, the NRC staff has held additional discussions with EPA;

the States of Nebraska, New Mexico, and Wyoming; and the industry. As a result of these

discussions, the staff prepared SECY-03-0186, “Options and Recommendations for NRC

Deferring Active Regulation of Ground-Water Protection at In Situ Leach Uranium Extraction

Facilities,” dated October 29, 2003 (ML031210874). In this SECY, the staff recommended 

that the NRC defer such active regulation to EPA-authorized non-Agreement States through 

the development of a Memorandum of Understanding (MOU or agreement) with individually

affected States. In a Staff Requirements Memorandum dated November 19, 2003,

(ML033230208) the Commission approved the staff’s recommendation and directed the staff to

develop a RIS to obtain public comment about this proposal before proceeding with the

development of an MOU with each appropriate State.

On February 23, 2004, NRC issued RIS 2004-02 (ML040550197) to request that, on a

voluntary basis, addressees and other interested parties submit information pertaining to the

proposed deferral of active regulation of ground-water protection at ISL uranium extraction

facilities. A notice of availability was published in the Federal Register on March 12, 2004

(69 FR 11899). The comment period closed on April 11, 2004.

SUMMARY OF ISSUE

The NRC plans to enter into an MOU, with each State, to defer active regulation of both

licensing and inspection activities for ground-water protection. This process began with an

initial official contact with the appropriate program director in each State, by the Director of the

Office of Nuclear Material Safety and Safeguards, requesting agreement to begin the MOU

process (ML033570409 and ML033570472). As part of the agreement process, the NRC staff

will work with each State to compare its ground-water protection program with that of NRC’s. 

This comparison will examine the general review areas and staffing of each State, similar to the

Integrated Material Performance Evaluation Program review performed for Agreement States. 

The NRC staff will use NUREG-1569, “Standard Review Plan for In Situ Leach Uranium

Extraction License Applications,” as the basis for performing the programmatic comparison with

each State. Areas identified as essentially equivalent to the NRC program will be included in

the MOU as programmatic areas where NRC will defer active regulatory oversight to the State. 

Any areas determined not essentially equivalent to the NRC program will be identified in the

MOU as areas where the NRC will continue its direct regulatory oversight. Only the production 
RIS 2004-09

Page 3 of 5

well-field ground-water protection aspects of the NRC’s licensing and inspection programs will

be deferred to the State. The NRC will enter into an MOU with the State, if the NRC concludes

that the State’s ground-water protection program is equivalent to the NRC’s program, providing

adequate protection of public health and safety, and the environment.

The following table provides information concerning the currently operating ISLs in nonAgreement States.

Cogema Wyoming SUA-1341 040-008502

Power Resources, Inc. Wyoming SUA-1548 040-008964

Based on the NRC staff’s experience in working with Nebraska and Wyoming, it expects that

the comparison will result in finding that these States’ ground-water protection programs are

equivalent to NRC’s.

On successfully completing an MOU with a State, the NRC will then amend each of the affected

ISL licenses at the request of each licensee. The amendment will remove, as appropriate, the

specific conditions pertaining to ground-water protection. Each amendment will be subject to

an environmental review and a notice of opportunity for a hearing, in accordance with current

NRC policy and practices. Thereafter, the NRC will periodically document its review of UIC

permits and State inspection reports, as well as State-identified program changes, to determine

that the State continues to conduct an acceptable program in accordance with the MOU. The

NRC will continue to conduct licensing reviews and inspections for public and worker radiation

safety at the affected ISL facilities. 

Although implementation of this approach will initially require the expenditure of additional NRC

staff resources to achieve the agreements before any resource savings will be realized, the

approach offers several advantages. The current dual regulatory burden of the NRC and State

reviews of the licensees will be eliminated once the agreement is finalized. Public health,

safety, and environmental protection, with regard to ground-water, will be assured at licensed

ISL facilities through the State’s direct oversight. At the same time, the NRC will retain its

authority to regulate ground-water protection at ISLs and can re-enter active regulation in this

area if a State’s program became inadequate. The effectiveness and efficiency of the NRC’s 

ISL licensing program will be enhanced by making its active role clear to the licensee and other
RIS 2004-09

Page 4 of 5

stakeholders. In time, it is anticipated that the initial outlay of resources to develop the MOUs

will be more than offset by the gains from reductions of reviews.

Summary of Comments on RIS 2004-02:

Comments on the proposal described in RIS 2004-02 were received from the States of New

Mexico, Texas, and Wyoming; the Wyoming Mining Association; the National Mining

Association (NMA); the Nuclear Energy Institute (NEI); Crow Butte Resources, Inc.; and Power

Resources, Inc. All comments were favorable and supported NRC’s proposal to defer active

regulation in this area using the MOU process discussed in RIS 2004-02. 

NEI commented that the NRC should relinquish regulation of all in-situ well-field operations. 

NEI stated that such operations are equivalent to the mining of ores in conventional open pit or

underground operations that are not subject to NRC licensing. In response, NRC staff pointed

out that ISL operations involve the in-place (i.e., in-situ) processing of ores to extract (i.e.,

recover) the uranium; therefore, unlike conventional open pit or underground mining in which

the ore is removed from the earth and the uranium is later extracted from the ore in a mill, the

extraction of the uranium for ISL processes occurs directly in the ore deposit. The NRC has

jurisdiction and licensing authority over the milling of uranium (as defined in 10 CFR 40.4). 

Therefore, we have concluded that for the NRC to relinquish its regulatory authority over the

extraction portion of ISL operations, either a State must enter into an agreement with the NRC

which provides for the discontinuance of the NRC’s regulatory authority over the activities

associated with uranium and thorium recovery facilities pursuant to section 247b. of the Atomic

Energy Act of 1954, as amended (AEA), or a statutory change would be necessary. We are not

convinced at this time that a statutory change would be a cost effective undertaking.

NMA commented that the process described in RIS 2004-02 could be rather lengthy. NMA

encouraged the NRC to use the appropriate personnel and needed resources to move forward

with the process as expeditiously as possible. In response, NRC will apply the available

resources that are needed, consistent with its budget and other priority work. 

The State of Wyoming commented on the contents of the example MOU that was included as

an attachment to RIS 2004-02. The State of New Mexico commented that a detailed review of

the example MOU would be needed before entering into an agreement. Each MOU will be

unique because of circumstances unique to each State. Because of these circumstances,

discussions with each State will be necessary to develop final MOUs; therefore, an example

MOU is not included with this RIS. Similarly, the States’ comments on the example MOU have 

not been included.
