NUCLEAR REGULATORY COMMISSION
[Docket No. 40-8943]
Crow Butte Resources, Inc.
AGENCY: Nuclear Regulatory Commission.
ACTION: Final finding of no significant impact; notice of opportunity
for hearing.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) proposes to renew
NRC Source Material License SUA-1534 to authorize the licensee, Crow
Butte Resources, Inc. (CBR), for continued commercial operation of its
in-situ leach (ISL) uranium mine and processing facility, located in
Dawes County, Nebraska. This license currently authorizes CBR to
receive, acquire, possess, and transfer uranium at the Crow Butte
Uranium Project, which is located approximately eight kilometers (five
miles) southeast of the town of Crawford, Nebraska. An Environmental
Assessment was performed by the NRC staff in support of its review of
CBR's license renewal request, in accordance with the requirements of
10 CFR Part 51. The conclusion of the Environmental Assessment is a
Finding of No Significant Impact (FONSI) for the proposed licensing
action.

Branch, Mail Stop TWFN 7-J8, Division of Waste Management, Office of

Commission, Washington, D.C. 20555. Telephone 301/415-6699.
SUPPLEMENTARY INFORMATION:
Background
At the Crow Butte facility, the ISL mining method involves: (1) The
injection of native groundwater, with added sodium carbonate/
bicarbonate and oxygen or hydrogen peroxide, into a uranium-bearing
orebody through injection wells; (2) the chemical mobilization of the
uranium through oxidation and then complexation with the carbonate
species; and (3) the extraction of the uranium-bearing solution from
the subsurface through a pattern of pumping wells. The uranium is
separated from the leach solution by conventional ion exchange methods
in the processing facility. The resulting uranium-poor solution is
recharged with carbonate and oxygen and returned to the mining zone for
additional uranium recovery. This cycle continues until the ore zone is
depleted or recovery of the uranium is no longer economically feasible.
The recovered uranium solution is processed further by using
ammonia or hydrogen peroxide to precipitate the uranium into a slurry.
The resulting slurry is thickened by gravity settling, and then washed
and de-watered in a filter press to about 50 percent solids. The filter
press solids (cake) are then dried in a natural gas vacuum dryer, to
produce uranium oxide, which is commonly known as ``yellowcake.'' The
dried yellowcake is packaged in 208-liter (55-gallon) steel drums for
storage and eventual shipment to a fuel processing facility.
CBR conducts uranium recovery operations within designated areas
(``mine units'') of the Crow Butte site; these mine units range between
4 to 16 hectares (10 and 40 acres) in size. A number of well patterns
are installed in each mine unit, with each pattern typically including
four injection wells laid out in a roughly rectangular shape and one
centrally-located pumping (production) well. Currently, CBR is
conducting uranium recovery operations in three mine units and
groundwater restoration in two other mine units in which uranium
recovery has been concluded. CBR has completed construction of a sixth
mine unit but has yet to initiate operations in it.
Summary of the Environmental Assessment
The NRC staff performed an appraisal of the environmental impacts
associated with the continued operation of the Crow Butte ISL facility,
in accordance with 10 CFR part 51, Licensing and Regulatory Policy
Procedures for Environmental Protection. In conducting its appraisal,
the NRC staff considered the following information: (1) CBR's license
renewal application, as amended; (2) previous environmental evaluations
of the Crow Butte facility; (3) CBR's license amendment requests
submitted subsequent to its renewal application, and NRC staff
approvals of such requests; (4) data contained in required semiannual
environmental monitoring reports; (5) results of NRC staff site visits
and inspections of the Crow Butte facility; and (6) consultations with
the U.S. Fish and Wildlife Service, the State of Nebraska Department of
Environmental Quality, and the State Historic Preservation Officer for
the State of Nebraska. The results of the staff's appraisal are
documented in an Environmental Assessment. The safety aspects for the
continued operation of the facility are discussed in a Safety
Evaluation Report.
The license renewal would authorize CBR to continue operating the
Crow Butte ISL facility, such that the plant throughput does not exceed
a flow rate of 18,930 liters (5000 gallons) per minute, exclusive of
the flow involved in restoring the depleted mine units. Annual
yellowcake production will not be authorized to exceed 907,185
kilograms (2 million pounds).
All conditions in the renewal license and commitments presented in
the licensee's license renewal application are subject to NRC
inspection. Violation of the license may result in enforcement action.
Conclusions
The NRC staff has re-examined actual and potential environmental
impacts associated with continued operation of the Crow Butte facility,
and has determined that renewal of Source Material License SUA-1534
will (1) Be consistent with requirements of 10 CFR part 40, (2) not be
inimical to the public health and safety, and (3) not have long-term
detrimental impacts on the environment. The following statements
[[Page 9024]]
support the FONSI and summarize the conclusions resulting from the
staff's environmental assessment:
1. The proposed groundwater monitoring program is sufficient to
detect excursions (vertical or horizontal) of mining solutions.
Furthermore, aquifer testing and the previous history of operations
indicate that the production zone is adequately confined, thereby
assuring hydrologic control of mining solutions;
2. Liquid process wastes will be disposed in accordance with
approved waste disposal options. Monitoring programs are in place to
ensure appropriate operation of the deep disposal well and to detect
potential leakage from the solar evaporation ponds;
3. An acceptable environmental and effluent monitoring program is
in place to monitor effluent releases and to detect if applicable
regulatory limits are exceeded. Radiological effluents from facility
operations have been and are expected to continue to remain below the
regulatory limits;
4. All radioactive wastes generated by facility operations will be
disposed offsite at a licensed byproduct disposal site;
5. Groundwater impacted by mining operations will be restored to
baseline conditions on a mine unit average, as a primary goal. If
baseline conditions cannot be reasonably achieved, the R&D operations
have demonstrated that the groundwater can be restored to applicable
class-of-use standards; and
6. Because the staff has determined that there will be no
significant impacts associated with approval of the license renewal,
there can be no disproportionally high and adverse effects or impacts
on minority and low-income populations. Consequently, further
evaluation of Environmental Justice concerns, as outlined in Executive
Order 12898 and NRC's Office of Nuclear Material Safety and Safeguards
Policy and Procedures Letter 1-50, Revision 1, is not warranted.
Alternatives to the Proposed Action
The proposed action is to renew NRC Source Material License SUA-
1534, for continued operation of the Crow Butte ISL facility, as
requested by CBR. Therefore, the principal alternatives available to
NRC are to:
(1) Renew the license with such conditions as are considered
necessary or appropriate to protect public health and safety and the
environment; or
(2) Renew the license, with such conditions as are considered
necessary or appropriate to protect public health and safety and the
environment, but not allow CBR to expand its operations beyond those
previously approved; or
(3) Deny renewal of the license.
Based on its review, the NRC staff has concluded that the environmental
impacts associated with the proposed action do not warrant either the
limiting of CBR's future operations or the denial of the license
renewal. Additionally, in the SER prepared for this action, the staff
has reviewed the licensee's proposed action with respect to the
criteria for license issuance specified in 10 CFR Part 40, Section
40.32, and has no basis for denial of the proposed action. Therefore,
the staff considers that Alternative 1 is the appropriate alternative
for selection.
Finding of No Significant Impact
The NRC staff has prepared an Environmental Assessment for the
proposed renewal of NRC Source Material License SUA-1534. On the basis
of this assessment, the NRC staff has concluded that the environmental
impacts that may result from the proposed action would not be
significant, and therefore, preparation of an Environmental Impact
Statement is not warranted.
The Environmental Assessment and other documents related to this
proposed action are available for public inspection and copying at the
NRC Public Document Room, in the Gelman Building, 2120 L Street N.W.,
Washington, DC 20555.
