DESCRIPTION OF THE PROPOSED PROJECT
(1) Proposed Dam, Spillway, Power Tunnel, Pm-Jerhouse, Tailrace, and
Access Road
Dam: The dam wi 11 be a non-overflow rockfi 11 type founded on
bedrock. The rockfi 11 wi 11 have a maxi mum hei ght of 308 feet
from e 1 evat ion 810 to ll18. The crest wi 11 be llOO feet in
length and 20 feet in width with a 7-foot high concrete coping
wall on the upstream edge to elevation 1125. The rcickfill in
the dam, with upstream slope of 1.7h:1v and downstream slope
of 1.5h:1v, will be zoned and compacted "in lifts with v'ibratory
compactors. The volume of the rockfill will be 2,500,000 cubic
yards. A concrete grout cap will be placed along the upstream
toe to grout the rock joi rot sets. The dam wi 11 be sealed
between the grout cap and the coping· wall "lith asphaltic con-
crete pavement on the upstream face with an average thickness
of 12 inches. Oversize rock will be placed against the down-
stream face as required for earthquake stability.
A 20-foot high cofferdam placed upstream from the grout cap
will divert the river flow through the power tunnel during dam
construction. The cofferdam will not be removed.
A typical dam section is shown on Figure 1-1.
Spillway: The probable maximum flood for the Kisaralik River
has not been determined. For estimating purposes, an ungated
side channel spillway at elevation 1110 with a channel width

of 375 feet and a slope of 5% is expected to pass the probable
maximum flood (PMF) before overtoppi ng the dam. The desi gn
discharge of the spillway is 87,000 cfs.
The spillway will be excavated in bedrock around the right (north)
abutment of the dam and discharge into the side canyon downstream
from the powerhouse.
Power Tunnel and Intake: A horseshoe tunnel 650 feet in length and
minimum rock excavation di ameter of 18 feet wi 11 1 ead from the
powerhouse through the ri ght abutment to an intake structure
located upstream .of the cofferdam. The tunnel wi 11 slope 0.020
downstream and be concrete lined to a finish diameter of 16 feet.
The concrete power intake structure wi 11 be fl ared to reduce
entrance losses and be provided with a trashrack, having slots.for
an emergency closure gate. The gate operator will be located above
the highwater at elevation 1125. The gate stem will be sealed in
an oil-filled housing to prevent freezing.
The downstream end of the tunnel will terminate in a trifurcation.
Two legs of the trifurcation will be connected to turbines in the
powerhouse for power gene rat i on and the thi rd used as a bypass
during construction. The bypass will remain for future emergency
drawdown.
Powerhouse: The powerhouse will be an underground cavern
approximately 100 feet long, 65 feet wide, and 60 feet high
excavated in bedrock. Reinforced concrete will enclose the draft
tubes and spiral cases. The turbine pit, turbine floor,
- 4 -
APAI8/F
turbine floor walls and generator floor will be reinforced
concrete. The walls above the generator floor and the ceiling
will be unlined, natural rock; rock bolted and/or gunited as
required for stability. Personnel and equipment will be protected
from spalling rock with an aluminum alloy shield suspended from
rock bolts in the crown of the cavern.
The powerhouse will contain 2 vertical Francis turbines and
generators rated at 15 MW each.
An appropriate sized overhead travelling crane will be installed
for erection and maintenance of the generating equipment.
The tunnel and powerhouse are shown on Figure 1-2.
Tailrace: Water will be returned to the river through a 22-foot
diameter unlined tunnel approximately 225 feet long.
Access Roads: There are no access roads to the site at the present
time. A winter access road approximately 69 miles in length from
Bethel to the project site will provide the means of construction
mobilization and demobilization.
A permanent road approximately 2 miles in l~n~th will b~ constructed
downstream from the powerhouse to the concrete aggregate borrow
area. A gravel airstrip will be constructed at the end of the road
for project access with fixed wing aircraft.
Refer to Exhibit 4 for location of access roads and the airstrip.

A substation at the powerhouse will transform the generated
voltage of 13.8 kV to 138 kV. Utilization of 138 kV nominal
voltage and a 795 MCM conductor will assure adequate voltage
levels in Bethel. Energy losses will be low due to the
relatively large conductor chosen. An overhead line will
strike northwest for approximately 56 miles turning sharply
northward near Kwethluk and cross the Kuskokwim River. The
line will then strike southeast for 13 miles and terminate in
a substation near Bethel. The transmission corridor will
generally parallel the access road.
Refer to Exhibit 4 for location of the transmission corridor.

Land Status: The power-development site is presently located
within the proposed Yukon Delta Wildlife Refuge (Federal Land
Policy Management Act of November 16, 1978, Emergency Order
204E). The 204E withdrawal is valid for 3 years. The Kisaralik
River is also considered under Emergency Order 204C, which has
not been invoked yet. This order would withdraw the river and
a 2-4 mile corridor along each bank for a period of 20 years
and be more restrictive than the 204E order. If bills HR38 or
S9 pass, the Kisaralik might also be included in the IIWild and
Scenic River" system.
The Kisaralik River flows across f~deral, state, and Native
lands. Kisaralik Lake and the river downstream about 15 miles
(west boundary T3N, R60W) are within lands patented to the
State of Alaska. From there downstream about 67 river miles
(west boundary T8N, R65W), the river flows through lands owned
by the federal government and managed by the Bureau of Land
Management. Both segments are proposed as a wild river. The
remaining 25 miles of the Kisaralik River lie within lands
selected by the Akiak Village Native Corporation.

(6) Additional Information on Development, Conservation, and
Utilization in the Public Interest of Regional Water Resources
The Bethel area presently utilizes diesel generation exclu-
sively and is experiencing very high increases in electric
energy costs due to the recent escalation of fuel oil prices.
Alternate developments have therefore been compared to the
basic case of continued exclusive diesel generation.
The most promising development plan has been found to be
development of the hydroelectric potential of the Kisaralik
River. It has been preliminarily assessed as feas'ible 'in
regard to cost, capacity, environmental impact, and land
status.
The proposed hydroelectric site on the Kisaralik River has the
potential to supply the entire future needs of the Bethel area
through the year 2000. The energy from the project can be
absorbed by interconnecting numerous small villages surrounding
Bethel to a centralized power distribution point located in
Bethel, which is in turn supplied via a 69-mile-long trans-
mission line from the project.
Over a 20-year period, assuming the project could go on-line
in 1986, a savings of 255,000,000 gallons of diesel oil could
be realized.

DESCRIPTION OF STUDIES CONDUCTED OR TO BE CONDUCTED WITH RESPECT TO THE
PROPOSED PROJECT
(1) General Requirement
The proposed site was investigated during preparation of a
study for the Alaska Power Authori ty by Robert W. Retherford
Associates, Anchorage, Alaska, entitled IIReconnaissance Study
of Ki.";aralik River Hydroelectric Power Potential and Alternate
Electric Energy Resources in the Bethel Area ll dated February 1980.
I n general, the proposed work wi 11 be performed, and the
results organized, in a manner suitable for an Application for
Li cense before the Federal Energy Regul atory Commi ss i on. The
studies described below will be made to determine the technical,
economic, and financial feasibility of the project, taking
into account its environmental impacts.
Appropriate measures will be exercised at all times during the
field studies to prevent irreparable damage to the environment
of the proposed project. All test sites shall be restored as
closely as possible to their original condition to the satisfac-
t i on of the Commi ss i on and the Bureau of Land Management.
(i) Studies, Investigations, Tests and Surveys
• Geological: A preliminary site inspection, for field
evaluation of geology, soils, and geological hazards,
was made in the summer of 1979. This
-14 -
APAI8/F
information was used for the preparation of a pre-
liminary appraisal of the suitability of the Kisaralik
site for hydroelectric development. The findings of
this preliminary geological appraisal indicated that
a dam could be constructed in the proposed location.
Further geological investigations will be made to
support preliminary designs and cost estimates.
These wi 11 i ncl ude cori ng at both abutments of the
dam, at the intake structure, along the power tunnel,
and in the powerhouse area. It is anticipated that
approx imate ly two cori ngs wi 11 'be made on each
abutment of the dam, two cori ngs at the intake
structure, two corings along the tunnel alignment,
and two cori ngs in the powerhouse area. Surfi ci a 1
geological sampl"ings will be used to confirm the
orientation of bedding planes predicted from core
drilling activities. Copies of geological reports,
results of tests and analyses, and other information
secured during these investigations shall be furnished
to the Commission.
• Surveys: The surveys to be performed will i ncl ude
those necessary for preparing Exhibits J, K, and L
and other appropriate sections of an Application for
License. Surveys will be conducted by on-the-ground
survey crews and by aerial photogrammetry.
The ground crews will establish control and premark
panel points fot' the aerial photogrammetric work,
set permanent bench marks, make ties to geological
investigations and prepare detailed topography of
the principal features of the production plant.
-15 -
APAI8/F
Upon establishment of ground control and setting of
pane 1 s, vert i ca 1 aeri a 1 photography at a nomoi na 1
photo scale of 111 = 3,500' wi 11 be made duri ng the
fi rst acceptable v/eather in the area. Fo 11 owi ng·
acquisition of the aerial photography, topographic
maps of the project area, including the transmission
route and access road, will be made at a scale of
1" = 1,000', with a 20' contour interval.
• Hydro 1 09i ca 1: Us i ng data synthes i zed from nearby
drainage basins and existing climatological records
at Bethel, an estimated discharge per square mile
was prepared for the preliminary appraisal report.
This information allowed for preliminary sizing of
the dam, power tunnel, and turbi ne-generator capacity.
A gauge will be installed at or near Lower Falls on
the Ki sara 1 i k for the purpose of determi ni ng the
stage and flow of the river. The design, location,
and time of installation of the gauge, the rating of
the station, and the determination of the flow of
the river will be made under the supervision of, or
in cooperation with
Geological Survey.
the river shall be
the cognizant office of the U.S.
Records of the stage and flow of
kept for use in design of the
project and will be made available, to the commission.
The flow of the river measured at this station will
be correlated with flows of comparable streams and
with precipitation data to establish a synthetic
stream fl ow record. Thi s record wi 11 be used for
reservoi r operations studi es to confi rm the dam
height, installed capacity, and other parameters.
-16 -
APA18/F
• Reservoir Operations: Using preliminary hydrological
study data, the drawdown duri ng the dri est peri od
was evaluated to determi ne the mi ni mum dependable
fl owrate, and thereby est-imate the prime capacity of
the project.
After refined hydrological information is developed,
a computeri zed reservo; r ope rat i on study wi 11 be
made. Pri me capacity, optimum dam hei ght, and
optimum installed capacity will be determined.
Economic constraints (including reserve requirements
and operation and maintenance) will be evaluated and
an installed capacity and combination of turbine-
generator sets will be determined.
• Project Structures: Following a review of preliminary
geological, hydrological, and reservoir operation
studies, the cost estimate for the dam, spillway,
power tunnel, powerhouse, tailrace, and transmission
1 i ne (i nc 1 udi ng the wi nter access road), and the
permanent access road from the airport to the dam
site were prepared.
During the period of the preliminary permit, refined
cost estimates will be prepared for the project.
This cost estimate will include engineering costs,
interest during construction, and other intangible
costs. Cost estimates will be prepared for alterna-
tive sites.
-17 -
APAI8/F
• Alternatives: Several alternatives have been evaluated
for the preliminary appraisal report, generally on
the basis of cost, environmental, and power generation
potent i a 1. The a 1 ternat i ves inc 1 uded hydroe 1 ect ri c
potential, coal and wood energy conversion, geothermal
potential, wind potential, transmission -jnterties,
and conservation. The Kisaralik River Hydroelectric
project was selected as the alternative most suitable
for development.
A brief summary of the alternative development plans
wi 11 be prepared. A summary of the envi ronmental
impacts anticipated from the construction of the
alternatives will be collected. Details regarding
viable alternatives, including costs, feasibility,
and power generation will be collected.
• Economic Analysis: The project economic analysis
will consider both annual cash flows and net present
worth when se 1 ect-j ng the recommended development
plan. Various development plans will be analyzed
with respect to annual cash fl 0'/1 for capital and
operating costs to identify those plans which can be
supported by anticipated system revenues duri ng the
earlier years of project operation.
• Environmental Assessment: A general overview of
potential projects in the Bethel area, to eliminate
projects with heavy environmental impacts, particularly
wi th respect to anadromous fi sh, wi 11 be made.
-18 -
APA18/F
A detailed report, presenting the existing socio-
economic status and flora and fauna in the project
area, will be prepared. The effect of the project
on man and the envi ronment wi 11 be evaluated and
mitigative measures proposed.
(ii) Access Roads: No new roads will be built for the purpose
of conducting the studies.
(2) Work Plan for New Dam Construction
(i) Description of Activities: It is not anticipated that any
field study, test or' other activity will significantly
alter or disturb lands or waters in the vicinity of the
project. It is anticipated that a BLM permit will be
requi red for conducting thi s work. Fo 11 owi ng are the
guidelines which the applicant intends to follow during
the course of the field studies proposed above:
Access for personnel and equipment will be by air,
water, or on foot. There will be no road construction
under this preliminary permit.
• No trees over 6-inch diameter at breast height will
be cut without prior authorization.
• The tent camp will be ma"intained in a sanitary
condit"ion. Burnab"le refuse will be burned in a
fire-safe container. All unburnables will be placed
ina sani tary 1 andfi 11 . All other materi a 1 s, wi th
the exception of survey monuments and stream gauge,
will be removed. This includes, without limitation,
containers, tents, drilling equipment, etc.
-19 -
APAIS/F
• No waste or by products wi 11 be di scharged into
streams. Storage facilities for materials capable
of causing water pollution, if accidently discharged,
will be located so as to prevent any spillage into
waters or channels leading into water.
• If, during activities under the permit, items of
substantial archeological or paleontological value
are discovered, the area so affected will be vacated.
Proper authorities will be notified and no further
work in the affected area will resume until written
approval is given.
• The permittee will protect the scenic esthetic
values of the area under permit, and adjacent land,
as far as possible within the authorized use. Test
pits will be backf"i1led to the original contour.
Harassment of wildlife will be cause for dismissal
of the offender.
• Activities will be strictly limited to geologic
exp 1 orat ion, core dri 11 i ng, surveyi ng and other
items as they may pertai n to the gatheri ng of
information for an Application for License to
construct the project.

The cost of power to be generated by the proposed project
assumes a 1986 start-up date. A comparison of the cost of
power from the proposed project with continuing use of diesel
generation is as follows:
Hydro Diesel
Mi 11 s/kWh t~i 11 s/kWh
Interest Rate 1986 2000 1986 2000
2% 211 114 162 323
5% 295 149 165 329
7% 365 178 168 334
9% 438 208 171 340
It is not anticipated that these rates will be charged to the
consumer. The breakeven pO'j nt for di ese 1 vs. hydroe 1 ectri c
energy will probably not occur until 1995. Some form of
subsidized energy will be required until the project is capable
of deriving sufficient revenue to meet the debt-service require-
ments. The details of this subsidized arrangement have not
been finalized. The applicant is, however, in a position to
make the required arrangements.
