DEPARTMENT OF ENERGY
Bonneville Power Administration
Billy Shaw Dam and Reservoir
AGENCY: Bonneville Power Administration (BPA), Department of Energy
(DOE).
ACTION: Finding of no significant impact (FONSI) and floodplain/wetland
statement of findings.
-----------------------------------------------------------------------
SUMMARY: This notice announces BPA's decision to fund the construction,
operation, and maintenance of the Billy Shaw Dam and Reservoir on the
Duck Valley Reservation. This project is part of a continuing effort to
address system-wide fish and wildlife losses caused by the development
of the hydropower system in the Columbia River Basin. BPA has prepared
an Environmental Assessment (EA) (DOE/EA-1167) evaluating the potential
environmental impacts of the proposed project. Based on the analysis in
the EA, BPA has determined that the Proposed Action is not a major
Federal action significantly affecting the quality of the human
environment, within the meaning of the National Environmental Policy
Act (NEPA) of 1969. Therefore, the preparation of an Environmental
Impact Statement (EIS) is not required and BPA is issuing this FONSI.
A finding is included that there is no practicable alternative to
locating the project within a 100-year floodplain.

SUPPLEMENTARY INFORMATION: Under provisions of the Pacific Northwest
Electric Power Planning and Conservation Act of 1980 (Act), BPA
protects, mitigates, and enhances fish and wildlife and their habitats
affected by the construction and operation of the Federal hydroelectric
system in the Columbia River Basin. This is accomplished through
funding of measures that are consistent with the Northwest Power
Planning Council's (Council) Fish and Wildlife Program and other
purposes of the Act [16 U.S.C. 839b(h)(10)(A)]. The site-specific fish
and wildlife mitigation projects that BPA funds are intended to help
reach the Council's mitigation goals and are ``in addition to, not in
lieu of, other expenditures authorized or required from other entities
under other agreements or provisions of law.''
The Proposed Action is for BPA to fund the construction and
operation of the Billy Shaw Dam and Reservoir (Project) on the Duck
Valley Reservation (Reservation). It is consistent with the objectives
of the Council's Program goals and satisfies the Council's
recommendation to implement an additional lake fishery at Coyote Sink
on the Duck Valley Reservation. Developing the Project would help BPA
meet the need to provide off-site mitigation in the Duck Valley area
for the loss of salmon and steelhead caused by the construction and
operation of the Federal hydroelectric dams and reservoirs on the
Columbia River. The No Action Alternative considered in the EA would
not satisfy BPA's need to provide off-site mitigation in the Duck
Valley Reservation area for salmon and steelhead.
The Project would include the construction of an earthen dam to
create a reservoir in the Billy Shaw Slough on the Reservation. The
water for the new reservoir would come from natural high spring flows
that would be diverted from the Owyhee River at the China Diversion Dam
and supplied through the Duck Valley Canal and the new Billy Shaw Feed
Canal. The new reservoir would have a surface area of 174 hectares (430
acres) and volume of 3300 acre-feet. The reservoir would be stocked
with trout from an existing fish hatchery.
Some environmental impacts would occur as a result of the Project,
but the impacts would not be significant. Approximately 223 hectares
(550 acres) of vegetation and wildlife habitat would be removed or
disturbed by the Project. Approximately 174 hectares (430 acres) of
suitable foraging habitat for various animal species, including
federally listed bald eagles, and suitable nesting habitat for
burrowing owls and pygmy rabbits would be permanently replaced by a
reservoir. An additional 49 hectares (120 acres) of habitat would be
temporarily disturbed by construction activities. The vegetation and
habitat disturbance and removal would not be significant because
similar vegetation and habitat is plentiful in the area. The impact
area represents less than 3% of the Billy Shaw Slough monotypical
vegetation and habitat communities.
Another vegetation related impact would be the increase in plant
diversity along the reservoir shoreline. This impact would not be
significant because only native plants would be used for reseeding and
revegetating disturbed areas. This would prevent non-native plants from
being introduced into the local area by the Project.
Soil disturbance from construction and maintenance activities would
increase the risk of erosion. However, the impact would not be
significant because it would be limited to localized increases in
erosion and runoff. Although foraging habitat for bald or golden eagles
would be replaced by the new reservoir, the reservoir may contribute to
increased site use by bald or golden eagles, especially at the
reservoir or riparian fringe areas. No other threatened or endangered
wildlife are known to occur within the area. Impacts to the bald eagle
would not be significant because similar foraging opportunities are
plentiful in the area. Increased site utilization by bald or golden
eagles would not significantly impact any other wildlife resource.
The addition of the reservoir would increase the amount of fish
habitat in the area. The Project design and location would prevent the
reservoir fish from leaving the reservoir so there would be no impacts
to other aquatic environments. Approximately 1.2 hectares (3 acres) of
intermittent wetlands would be permanently replaced by the reservoir.
The impacts would not be significant because the wetlands are not part
of a complete and interrelated wetland area. New wetlands and riparian
areas would naturally develop in shallow areas around the reservoir
perimeter and would offset the loss of the existing intermittent
wetlands.
The Project would be developed within an area prone to spring
flooding from the Owyhee River. The Project would reduce seasonal
flooding below the dam site and would alter normal runoff patterns. No
impacts to lives or
[[Page 12161]]
property would occur because no facilities or habitation exist within
the area.
Impacts from construction activities on visual resources,
employment and economic opportunities, air quality, and public health
and safety would be minor and of short duration. After project
construction, the reservoir would attract additional wildlife and
diversify the viewing opportunities in the valley.
The location of the Project borrow site was not identified in the
EA because it is not known at this time. However, impacts to
vegetation, wildlife, and cultural resources would not be significant
because preconstruction surveys would be conducted if an undeveloped
borrow site is selected for use. If the surveys determine the presence
of sensitive resources such as endangered species or historic
properties, then the borrow site would either be relocated or
appropriate mitigation measures would be applied to ensure any impacts
are at a level below significant.
As stated in Chapter IV--Permit Requirements and Contacts of the
EA, the Project is subject to certain regulatory requirements. A permit
to fill in wetlands under Section 404 of the Clean Water Act would be
required. The Nevada Division of Environmental Protection may require a
letter of water quality certification or a rolling stock water
pollution control permit. The U.S. Army Corps of Engineers would
require an Impoundment Permit for the emplacement of the reservoir. In
accordance with the National Historic Preservation Act, a Class III
cultural resources survey was conducted and found no significant
resources. The Nevada State Historic Preservation Officer concurred in
a letter dated June 17, 1996 that the Project site was not eligible for
the National Register of Historic Places. In accordance with the
requirements of the Fish and Wildlife Coordination Act, the U.S. Fish
and Wildlife Service (USFWS) was consulted about this Project. The
Project is consistent with the Endangered Species Act because the EA
confirmed that no plant or animal species federally listed as
threatened or endangered would be adversely affected by the Project.
Floodplain Statement of Findings
This is a Floodplain Statement of Findings prepared in accordance
with 10 CFR Part 1022. A Notice of Floodplain and Wetlands Involvement
was published in the Federal Register on May 17, 1996 and a floodplain
and wetlands assessment was incorporated in the EA. BPA proposes to
fund the construction of an earth dam and reservoir in the Billy Shaw
Slough of the Duck Valley Reservation near Owyhee, Nevada. The Proposed
Action would be located in the floodplain because that area offers the
topographical qualities needed to fill and maintain a permanent
reservoir. The alternative to the Proposed Action, the No Action
Alternative, would not satisfy BPA's need to provide off-site
mitigation on the Duck Valley Reservation for the loss of salmon and
steelhead. The Proposed Action conforms to applicable State or local
floodplain protection standards.
Preliminary designs for the spillway and outlet works of the dam
included the small dam criteria available from the U.S. Department of
Agriculture Natural Resources Conservation Services (NRCS). The inflow
design floods were computed based upon NRCS, Idaho Department of Water
Resources, and Nevada Division of Water Resources criteria for
structures of this size and hazard classification. Although studies
indicated that a probable maximum flood event could be stored without
the use of the spillway, an emergency spillway would be included in the
plan. These design considerations would minimize any potential harm to
the floodplain should a significant flood event occur. Also, the
downstream hazard classification for the reservoir site is considered
low because no permanent or temporary human habitation or permanent
property development lies in the floodplain downstream from the
proposed damsite.
BPA will endeavor to allow 15 days of public review after
publication of this statement of findings before implementing the
Proposed Action.
Determination
Based on the information in the EA, as summarized here, BPA
determines that the Proposed Action is not a major Federal action
significantly affecting the quality of the human environment within the
meaning of NEPA, 42 U.S.C. 4321 et seq. Therefore, an EIS will not be
prepared and BPA is issuing this FONSI.
