NUCLEAR REGULATORY COMMISSION
[Docket No. 40-8857]
Power 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
Source Materials License No. SUA-1511. This license authorizes Power
Resources, Inc. (PRI) to receive, acquire, possess, and transfer
uranium at its Highland Uranium Project approximately 24 miles
northeast of the town of Glenrock, in Converse County, Wyoming. PRI's
Highland Uranium Project is an In-Situ Leach (ISL) uranium mine and
processing facility. An Environmental Assessment (EA) was performed by
NRC staff in support of PRI's license renewal request. The conclusion
of the Environmental Assessment is a Finding of No Significant Impact
(FONSI) for the proposed license renewal.

SUPPLEMENTARY INFORMATION:
Background
The ISL mining method involves: (1) Injecting a leaching solution
(lixiviant), comprised of native groundwater fortified with gaseous
carbon dioxide and oxygen, into a uranium-bearing ore body through
injection wells; (2) chemically mobilizing the uranium through
oxidation and complexing it with a carbonate ion in solution; and (3)
extracting the uranium-bearing solution through a pattern of pumping
wells. Uranium is then separated from the leach solution by
conventional ion exchange methods in a processing facility. The
depleted solution is recharged with carbon dioxide and oxygen and is
then returned to the mining zone for additional uranium recovery. This
cycle continues until the ore zone is depleted or the uranium is no
longer economically feasible to recover.
The recovered uranium solution is further processed by using
ammonia or hydrogen peroxide to precipitate the uranium into a slurry.
The resulting slurry is further thickened by gravity settling, then
washed and dewatered in a filter press to about 50 percent solids. The
filter press solids (cake) are then dried in a natural gas dryer, which
operates at about 1200 degrees Fahrenheit, producing uranium oxide
commonly called ``yellowcake''. The dried yellowcake is packaged in 55-
gallon steel drums for storage and shipment to a fuel processing
facility.
In the injection and extraction process, well patterns typically
include four injection wells at the corners of a 50- to 100-foot square
with one pumping (production) well centrally located. There are
currently six wellfields installed at the PRI Highland site, designated
as wellfields A through F. The A and B wellfields were constructed in
1987 and are now under restoration. The C wellfield was installed in
1989 and is still in production. The D wellfield was installed during
1990-1991 and started production in 1991. The E wellfield was built
during 1991-1992 and started production in 1992. The F wellfield was
approved by the NRC staff in 1994.
Environmental Assessment
The EA discusses the environmental aspects of the PRI renewal
request. Safety aspects for the continued operation of the Highland
Uranium Project are discussed in a Safety Evaluation Report (SER). The
license renewal would authorize PRI to continue operating the facility,
such that the annual throughput will not exceed an average flow rate of
7500 gallons per minute (gpm), exclusive of the flow involved in
restoring the depleted wellfields. Yellowcake production will not
exceed 1.897 million pounds annually. To assure that the process
emissions associated with this project are accurate, the licensee will
be prohibited by license condition from exceeding the 7500 gpm process
rate. All license conditions and commitments presented in the
licensee's Operations and Reclamation Plan are subject to NRC
inspection. Violation of the license may result in enforcement action.
An impact appraisal for the license renewal was performed by the
NRC, Division of Waste Management, and documented in the EA. The NRC
staff performed the appraisal of environmental considerations
associated with continuation of the ISL operation in accordance with
Title 10, Code of Federal Regulations (10 CFR) Part 51, Licensing and
Regulatory Policy Procedures for Environmental Protection.
In conducting this appraisal, the NRC staff considered the
following: (1) environmental, operational, and restoration information
submitted by PRI for previous and ongoing work at the Highland Uranium
Project, (2) additional information submitted in the licensee's
application, and (3) information derived from professional papers,
journals and text books, NRC Regulations and Regulatory Guides, as well
as other Federal, State and local agencies.
Conclusions
The NRC staff has reexamined actual and potential environmental
impacts
[[Page 44368]]
associated with the operations at PRI's Highland Uranium Project and
has determined that renewal of Source Materials License No. SUA-1511
will: (1) be consistent with the licensing requirements of 10 CFR 40,
(2) not endanger the public health and safety, and (3) not have long-
term detrimental impacts on the environment. Specific reasons for
drawing these conclusions are:
1. The proposed control and monitoring program for groundwater is
sufficient for detecting any excursion, either vertical or horizontal.
2. The radium settling basins and purge storage reservoirs are clay
lined to minimize seepage of waste solutions; monitoring systems as
designed should detect any leakage which may occur.
3. Radiological releases from the uranium extraction operations
will be very small (exposures which are small fractions of the
radiological exposure standards) and will be closely monitored to
detect any problems.
4. All radioactive wastes will be disposed of at an existing NRC
licensed tailings disposal site.
5. The proposed restoration plan, as demonstrated by the R&D ISL
test project, should be sufficient to return the groundwater to its
premining use (or potential use). On a parameter-by-parameter basis,
groundwater quality will be returned as close to baseline conditions as
reasonably achievable.
6. The remote location of the Highland Uranium Project facility and
sparse population in this portion of Converse County, Wyoming has
mitigated any potential adverse impacts to minority and low-income
populations. Further evaluation of `Environmental Justice' concerns, as
outlined in Executive Order 12898 and NRC's Office of Nuclear Material
Safety and Safeguard Policy and Procedures Letter 1-50 Rev. 1, is not
warranted.
Finding of No Significant Impact
Based on these conclusions, the NRC finds that the impacts
associated with the proposed renewal of Source Materials License No.
SUA-1151 are within the scope of impacts anticipated in the November,
1978 Final Environmental Statement (FES) and the July, 1987 EA; which
supported the initial licensing. Recognizing these impacts, the NRC has
available two alternatives with respect to the requested license
renewal: (1) Renew the license with such conditions as are considered
necessary or appropriate to protect public health, safety, and the
environment; or (2) deny renewal of the license.
The environmental impacts of the renewal described in the EA do not
warrant denial of the application. For this reason, the NRC has made a
finding of no significant impact associated with this action and will
issue a renewed license for the PRI Highland Uranium Project.
