NUCLEAR REGULATORY COMMISSION
[Docket No. 40-8964]
Rio Algom Mining Corp.; Final Finding of No Significant Impact
Notice of Opportunity for Hearing
AGENCY: Nuclear Regulatory Commission.
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) proposes to amend
NRC Source Material License SUA-1548 to allow the licensee, Rio Algom
Mining Corp. (Rio Algom), to employ deep well disposal of process waste
waters at its Smith Ranch in-situ leach facility as an alternate
disposal option for these wastes. An Environmental Assessment was
performed by the NRC staff 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.
FOR FURTHER INFORMATION CONTACT: Mr. James R. Park, Uranium Recovery
Branch, Mail Stop TWFN 7-J9, Division of Waste Management, Office of
Nuclear Material Safety and Safeguards, U.S. Nuclear Regulatory
Commission, Washington, DC 20555. Telephone 301/415-6699.
SUPPLEMENTARY INFORMATION:
Background
On March 12, 1992, the NRC issued to Rio Algom an NRC Source
Material License, SUA-1548, for commercial-scale uranium recovery
operations at Rio Algom's Smith Ranch in-situ leach (ISL) facility in
Converse County, Wyoming.
The NRC review of Rio Algom's license application is documented in
an Environmental Assessment (EA), issued on January 10, 1992.
Since the issuance of SUA-1548, Rio Algom has deferred commercial-
scale operations at the Smith Ranch facility due to the depressed
market for uranium. However, Rio Algom has indicated that it plans to
commence such operations in the Fall of 1997.
Summary of the Environmental Assessment
Identification of the Proposed Action
The proposed action is an amendment to SUA-1548 to allow Rio Algom
to employ deep well injection as an alternate disposal option for
process waste waters to be generated at its Smith Ranch ISL facility.
The NRC staff's review was conducted in accordance with the
requirements of 10 CFR 40.32 and 10 CFR 40.45.
Need for the Proposed Action
Rio Algom requested NRC approval of the proposed action to allow it
to employ deep well injection in the disposal of process solutions from
various waste streams that would be produced at the Smith Ranch
facility. Currently, Rio Algom is required by NRC license to return all
liquid effluents from commercial operations to the uranium recovery
process circuit or to discharge them to solution evaporation ponds.
Environmental Impacts of the Proposed Action
By this proposed action, Rio Algom is seeking to employ deep well
injection to dispose of a variety of process waste streams. These
process wastes would be injected at an average of 150 gallons per
minute from an injection well drilled to a total depth of 10,100 feet
below surface. The wastes would be injected into permeable portions of
the Parkman, Teapot, and Teckla formations, at depths below surface
ranging from 8700 to 9600 feet. Due to high levels of total dissolved
solids, groundwater in these formations has been designated by the
State of Wyoming, Department of Environmental Quality (WDEQ), as Class
VI water (unsuitable for use).
The Smith Ranch facility is not currently operating. As a result,
Rio Algom provided anticipated ranges in concentration of the principal
chemical species to be contained in the composite solution. The ranges
in concentration of constituents identified by Rio Algom are comparable
to concentrations allowed by the NRC at other ISL facilities employing
deep well disposal of process fluids.
The NRC staff limited its analysis to a review of the radiological
aspects of
[[Page 6268]]
the proposed action, in accordance with 10 CFR 20.2002. To avoid
duplication of review efforts with the State of Wyoming, the NRC staff
relied on the State's analysis of the suitability of the proposed
aquifers as injection zones. The WDEQ, on September 29, 1995, granted
an Underground Injection Control (UIC) permit to Rio Algom for the
construction and operation of a Class I injection well at the Smith
Ranch ISL facility.
Based on the nature of the proposed action, the NRC staff considers
the potential impacts to the general environment and offsite
individuals to be negligible for the following reasons:
(1) Under the State of Wyoming's groundwater classification system,
the groundwater in the formations to be impacted is considered to be
Class VI (unsuitable for use);
(2) The risk of exposure to the general public from the injected
fluids is negligible due to the depth below surface at which process
fluids will be injected (approximately 8700 to 9600 feet);
(3) Rio Algom will be continuously monitoring the disposal well to
detect and minimize a potential spill on the surface and thereby
preclude the release of effluent to the unrestricted environment;
(4) Rio Algom's radiation protection program in place at the Smith
Ranch facility will adequately minimize potential exposures to as low
as is reasonably achievable (ALARA); and
(5) At the end of the disposal well's useful life, the disposal
well system will be abandoned in accordance with the requirements of
Rio Algom's Class I injection well permit with the WDEQ.
Conclusion
The NRC staff concludes that approval of Rio Algom's amendment
request to employ deep well disposal as an alternate waste disposal
option at its ISL facility will not cause significant environmental
impacts. The NRC staff also finds that the proposed action is in
accordance with 10 CFR 20.2002 and with the NRC ``Staff Technical
Position on Effluent Disposal at Licensed Uranium Recovery Facilities''
(60 FR 27993; May 26, 1995).
Alternatives to the Proposed Action
Since the NRC staff has concluded that there are no significant
environmental impacts associated with the proposed action, any
alternatives with equal or greater environmental impacts need not be
evaluated. The principal alternative to the proposed action would be to
deny the requested action. Since the environmental impacts of the
proposed action and this no-action alternative are similar, there is no
need to further evaluate alternatives to the proposed action.
Agencies and Persons Consulted
The NRC staff consulted with the State of Wyoming, Department of
Environmental Quality, in the development of the Environmental
Assessment. In a telephone conversation on February 5, 1996, Mr. Robert
Lucht, UIC Program Supervisor, Water Quality Division of the WDEQ,
stated that the WDEQ had no objections to the conclusions reached in
the Environmental Assessment.
Finding of No Significant Impact
The NRC staff has prepared an Environmental Assessment for the
proposed amendment of NRC Source Material License SUA-1548. 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 NW.,
Washington, DC 20555.
