As published in The Curlew, March 2008 To jump to the LCBAS Comment Letter sent to Bureau of Reclamation, click here. Black Rock We have a number of concerns over this project and its impacts on the Hanford Reach National Monument and the Yakima and Columbia rivers. Large plumes of highly contaminated groundwater lie beneath the Hanford Reservation, a constant unseen threat to the Columbia River. For the most part, these contaminated ground waters are stable and contained deep underground. We must not allow highly toxic contaminates to be flushed into the Columbia River. The Department of Energy is striving to monitor, remediate and shrink these plumes, but they need time. Our first line of defense is to reduce the natural and artificial recharge of Hanford groundwater. The proposed Black Rock dam would be located within five miles of Hanford's western boundary. The dam would be 755 feet tall, well over a mile in length and back up a reservoir 10 miles long holding 1,300,000 acre-feet of water pumped from the Columbia River. The dam would overlook Dry and Cold Creeks; intermittent stream courses which meander onto the Hanford Reservation. The study predicts that water seeping from the dam and reservoir would flow towards the Hanford Reservation at the rate of 31 cubic feet per second. That does not sound like much but it would almost quadruple the annual groundwater flow under these stream beds to 30,000 acre-feet of water. Quadrupling the ground water flow under Hanford could easily mobilize contaminated plumes, forcing them into the Columbia River creating an environmental disaster on our door step that would be virtually impossible to contain or clean up. The Department of Energy is currently studying the potential impacts of this seepage on Hanford but the DOE report is months from completion. The Bureau of Reclamation / Ecology study is fatally flawed by its failure to include Energy's groundwater report. The Bureau and Ecology are rushing to a decision without critical information. What if the dam failed and sent 1,300,000 acre feet of water roaring down those dry creek beds in a wave several hundred feet tall right into the heart of Hanford. Impossible!!! Far fetched, typical tree hugger doomsday scare tactics. I think not. The feasibility study admits the dam would be located in an area of "relative high earthquake potential" with a "level of ground shaking that might be associated with the occurrence of magnitude 6 to 7+ earthquakes". The dam would straddle the Black Rock Valley fault "capable of a large-magnitude earthquake and that associated fault offsets within the dam footprint could range from a few centimeters to several meters." The right abutment of the proposed dam and southern edge of the reservoir lie in an area prone to landslides. The study warns "though the slide areas are currently stable, seepage from the reservoir into the presently unsaturated basalts and interbedded sediments would increase pore pressures within those materials and would likely reactivate some of those slides as well as initiate new landslides along the rim and dam abutments." Would the dam fail - no one really knows. Could the dam fail? Absolutely!!! Catastrophic failure of the dam would have the potential to sweep untold tons of nuclear waste into the Columbia. Black Rock's threat to Hanford groundwater is only one of many concerns I have for this project. Introducing Columbia River water into the Yakima can cause migrating salmon to be confused and disrupt their migration. The project will block the wildlife migration corridor between the Hanford National Monument and the Yakima Firing Center which also links wildlife populations to the Cascades. The project could jeopardize salmon spawning and migration in the Hanford Reach by reducing Columbia River flows. The feasibility report grossly overestimates the recreational potential of Black Rock, predicting 700,000 visits per year. At $4.5 billion, the project is far too expensive, and consumes enormous amounts of electricity ($50 million annually) which could be put to better use. The report is silent on who will pay the bill; but I think you know. The report leaves too many questions unanswered and provides insufficient factual information to meet the high standards of an Environmental Impact Statement and should be viewed as no more than a feasibility study. In view of these concerns, we strongly recommend that the Bureau of Reclamation and Department of Ecology drop Black Rock from further consideration and go back to the drawing board to seek other alternatives to meet our water needs. In the event a decision is made to proceed with this ill-conceived project we recommend the following actions be taken to mitigate some of our concerns:
Please, please send your comments in by March 31st. The proponents of the project want to get this thing on the fast track and are making a lot of noise. We desperately need your help.

Kaumheimer
Thank you for this opportunity to comment on the Draft Planning Report / Environmental Impact Statement for the Yakima River Basin Water Storage Feasibility Study issued in January 2008. We have many concerns with the report and associated projects. The report has been constructed as a draft plan, draft environmental impact statement and a feasibility study reviewing two major dam and reservoir projects and three state alternatives. The projects and alternatives have little in common except being found in the Yakima River basin. The report does not name a preferred alternative or indicate how a mix of the projects and alternatives will provide sufficient water for fish and agriculture. The reader is left to ponder whether the agency is considering going forward with all the projects and alternatives or a mix. The report falls short on comparing and contrasting these alternatives or how they would impact each other if a mix were selected. The report attempts to do too much at one time and in the end, fails to adequately address how these projects and alternatives could accomplish the mission of providing water for fish, agriculture and urban areas in the right amount at the right time. The report fails to adequately address the impacts of these projects and alternatives on the environment and our cultural heritage. The report fails to adequately address the impacts of the Black Rock project on Hanford ground water. Serious geological questions remain unanswered. The Black Rock and Wymer dam project’s impact on regional electrical supplies has not been addressed. The Recreational report is flawed and grossly exaggerates the potential visitor usage. We strongly recommend that the report be reclassified as a draft plan and feasibility study only. Additional information is needed on Hanford ground water and geological concerns. More information is needed on the engineering details of the dams. On the ground surveys of wildlife, native plants and cultural resources need to be done. Simply stated the report does not meet the rigorous standards of the National Environmental Policy Act for Environmental Impact Statements. We realize this will be costly in terms of time, labor and printing but a comprehensive, in depth EIS utilizing all available data, subjected to intense peer and public review can save billions of dollars and avoid environmental catastrophes. If you decide to continue viewing this report as a draft environmental impact statement, we insist that the report be submitted to a panel of independent experts in the various disciplines, such as the National Academy of Sciences, to review the report in detail and attempt to resolve these shortcomings, before writing the final report. The remainder of my comments will focus on the Black Rock proposal. Ground Water Impacts: Large plumes of highly
contaminated ground water lie beneath the Hanford Reservation, a
constant
unseen threat to the Columbia River. For the most part, these
contaminated
ground waters are stable and contained deep underground. We must not allow highly
toxic contaminates
to be flushed into the Columbia River. The Department of Energy is
striving to monitor, remediate and shrink these plumes, but they need
time. Our first
line of defense is to reduce the
natural and artificial recharge of Hanford ground water. The proposed Black Rock dam
would be within five miles of Hanford’s western boundary. The dam would be 755 feet
tall and well over
a mile long in length, holding 1.3 million acre feet of water. The dam
would
overlook Dry and Cold creeks, intermittent stream courses that meander
onto the
Hanford Reservation. The study predicts water
would
seep from the reservoir at the rate of 31 cfs and move onto the Hanford
Reservation. The
report indicates that
this almost quadruples the ground water moving under Dry and Cold
creeks. This
does not sound like a lot of water, but it amounts to 30,000 acre feet
per year
– or the equivalent of an underground lake one foot deep covering
almost 47
square miles creeping under Hanford. Another underground lake of that
dimension
would be added every year, relentlessly building and pushing those
contaminated
pools closer and closer to the Columbia. The report also states in
Table ES.6
that the total ground water seepage towards the Columbia River would be
57
cfs. The study does
not indicate why
only 31 cfs would flow under Hanford, I can only infer from this that
there is
the distinct possibility that the 31 cfs prediction could climb to 57
cfs or a
84% increase over the present prediction. The study does not include
detailed maps of the Black Rock project or Dry and Cold creek
drainages. This
is a serious deficiency which inhibits the public’s ability to evaluate
the
proposal. The increased ground water
flows
could easily mobilize the contaminated pools under Hanford and push
them into
the Columbia River initiating and environmental disaster that would be
almost
impossible to control or clean up.
We can
not allow this to happen. The Department of Energy is
currently studying the possible impacts of seepage from Black Rock on
Hanford’s
ground water. The
report will be
completed sometime in 2008 and will be included in your Final Report. Your draft Environmental
Impact Statement is
fatally flawed by the failure to wait a few short months to include the
Department of Energy’s report in the draft EIS.
The public must have the opportunity to make an informed
review and
comment on this vital issue. You
are
rushing to a decision without some of the most vital facts. Seismicity / Geological
Threat: The Black Rock dam would lie
in
an area of high earthquake potential.
The report is vague and difficult to understand as to the
extent of the
threat. The report states on page 2-9 “at a return period of 10,000
years, the
estimated mean PHA is about 0.95g (acceleration of gravity), a level of
ground
shaking that might be associated with the occurrences of magnitude 6 to
7+
earthquakes….”. I
have no idea what that
means. Is “6 to 7+”
the Richter scale or
some other form of measurement? How
high
is the potential frequency or magnitude of the earthquake threat? The
report
really does not give the reader any concrete idea of the threat from
seismic
activity. NEPA
requires EIS’s to be
written in a manner understandable to the general public. Once again
the report
fails to meet the NEPA standards. The dam would be constructed
on
the Black Rock fault and an additional thrust fault.
The report provides only a very vague idea as
to the exact location of these faults.
I
would hope this information is available and am disturbed that it has
not been
released to the public in this report. The right abutment of the
dam
would rest on Horsethief Mountain.
We
are greatly concerned as to the fitness of Horsethief Mountain to
function in
this important role as the right hand foundation for a 755 foot high
dam or its
ability to safely hold back 1,300,000 acre feet of water. The report states on page
4-37: “Landslides are common in
the
Yakima Fold Belt and generally form on the over-steepened south limbs
of the
anticlines. Several
ancient landslides
have been identified on the Horsetheif Mountain anticline, which
comprises the
right abutment of the proposed Black Rock dam (Columbia Geotechnical
Associates, 2004). The
steeply dipping
orientation and layering of the low-strength sediments and the presence
of the
Horsethief Mountain Thrust Fault along the southern edge of the
reservoir
valley present a potentially hazardous combination.
Though the slide areas are currently stable,
seepage from the reservoir into the presently unsaturated basalts and
interbedded sediments would increase pore pressures within those
materials and
would likely reactivate some of those slides as well as initiate new
landslides
along the reservoir rim and dam abutments.” The Bureau of Reclamation’s
Appraisal Assessment of Geology at Black Rock Damsite, Technical Series
No.
TS-YSS-5 (December 2004) states on page 32: “This high level of shaking
leads to the potential of causing lower density embankment or
foundation
saturated soils to experience liquefaction, which is essentially a loss
of
strength that can result in large slope failures.” This statement should have
been
included in the EIS and been easily available to the public and not
lost in a
supporting document. The above sited report
provides
photographs of Horsethief Mountain which indicate the location of some
of the
landslides, but the photos only vaguely indicate where the dam would
abut the
mountain. These photographs should have been included in the
feasibility study
report. The report does not provide a detailed diagram of the proposed
dam. We are
provided with a very small
diagram of the intake structure at Priest Rapids Dam but no drawings of
the dam
are offered for our review. The report again is severely deficient in
this
respect. The report
should provide
detailed diagrams of the dam, and its relationship to Horsethief
Mountain and
the faults. These
diagrams should
provide views across the face of the dam, a cross section of the dam
and an
aerial view of the dam and Horsethief Mountain. The above sited geology
report
also states on page 35 concerning the design of the dam: “Large site investigation
and
materials testing programs will be needed to ensure the site conditions
are
well understood. Detailed
analyses will
be critical to ensure a safe design is developed.
In addition to these measures, such a design would
need to be independently reviewed by an expert board of consultants.” The EIS does not indicate if
the
dam design was ever reviewed by an “expert board of consultants”. We feel it is absolutely
essential that this
independent expert review be completed and included in a new draft EIS.
Once
again the draft EIS fails to include critical information. The EIS
should be
revised, expanded and reissued as a draft. Columbia River Water
Withdrawal: The report is confusing and
inconsistent as to the volume of water to be withdrawn from the
Columbia
River. The draft EIS states on page
2-40: “In years when the maximum
water
exchange occurs, Black Rock reservoir would release a total of about
600,000
acre feet annually.” Table 2.19 indicates the
average
water pumped into Black Rock at 640,693acre feet annually, with a
maximum of
1,077,510 acre feet. The
table predicts
the annual amounts that would be pumped over a 25 year period. Two of those years would
pump over 1,000,000
acre feet, five of those years would pump between 730,000 and 1,000,000
acre
feet and nine years the total would be between 618,000 and 730,000 acre
feet
annually. The Bureau of Reclamation’s
Appraisal assessment of the Black Rock Alternative Facilities and Field
Cost
Estimates, Technical Series No. TS-YSS-2 states in Table 1, the water
exchange
in wet and average years at 810,400 acre feet and 662,000 acre feet in
dry
years. Clearly, the maximum water
exchange exceeds 600,000 acre feet. The report must be
consistent in
this vital respect. Once again the report does not meet the NEPA
standard for
an EIS. Columbia River / Hanford
Reach
Impacts: The report only vaguely
alludes
to the impacts of withdrawing water from the Columbia River above
Priest Rapids
dam. The Columbia’s
Hanford Reach lies
just below Priest Rapids dam and above the confluence of the Yakima and
Columbia Rivers. The
Hanford Reach
contains the very best spawning grounds on the main stem of the
Columbia River
and adequate water flows are absolutely critical to the successful
spawning,
rearing and passage of these fish. The Black Rock project would
withdraw, on average 396,847 acre feet of water from the Columbia at
Priest
Rapids dam in September and October.
This is 62% of the average annual withdrawal according to
Table 2.19. The
project would divert this water from the
Hanford Reach at the most critical time for spawning and exactly when
flows are
significantly declining. The
report must
provide detailed information as to the anticipated impact these
withdrawals
will have on the Reach. The report should also
acknowledge that three additional off channel storage reservoirs for
Columbia
River water above Priest Rapids are in the planning stage. What would the cumulative
impact to the
Hanford Reach be from all these projects? Fish – False Attraction: We have great concerns over
the
mixing of Columbia and Yakima River waters and the confusion it could
cause
migrating fish. The report states Columbia
River
water entering the Yakima River from the project would range from .34%
to 1.62%
which is well under the 10% threshold laboratory experiments have
indicated
sockeye salmon can tolerate before discriminating between water sources. This is encouraging but we
feel more testing
should be done using Columbia and Yakima water on migrating fish native
to these
streams. We recommend that
feasibility
studies be conducted to determine if Black Rock project waters from the
Columbia Rivers could be diverted to create wetlands and completely
avoid
entering the Yakima River. These
wetlands could be very beneficial to fish and wildlife and provide
recreational
opportunities. Wildlife: The wildlife section of the
report quotes numerous studies but does not indicate if any on the
ground
wildlife and native plant surveys were done specifically for this
project by
Interior Department biologists. The report should be clear on this
point and if
these surveys were not done, they should be and the results published
in a new
revised draft EIS. The project would disrupt
wildlife migration between the Hanford Reach National Monument and
Yakima
Firing Center and extending on to the Cascades.
Land should be acquired linking the Yakima Firing Center
to the Hanford
Reach National Monument along the Columbia River.
These lands should be added to the Hanford
Reach National Monument. A
second
wildlife corridor should be established along the Rattlesnake Hills to
assist
wildlife in their movement. The reservoir as designed
would
be of minimal value to fish and wildlife.
The Black Rock reservoir should be redesigned to include a
number of
dikes, gates and pumps to maintain shallow wetlands as the reservoir is
drawn
down during the irrigation season.
These
wetlands would be beneficial to fish, wildlife and migratory birds. Maintaining these wetlands
would enhance the
scenic view as well as fishing and hunting opportunities. Recreation: The report foresees Black
Rock
Reservoir as a sportsman’s paradise and outdoor recreation Mecca. The 8,640 acre lake and
narrow band of
shoreline that would be acquired are expected to attract boat and shore
fishing,
swimming, picnicking, water skiing, jet skiing, hiking, wildlife
viewing,
horseback riding and off road vehicles.
The report estimates annual visitor days starting at
200,000 and quickly
climbing to 700,000. We
believe these
projections are grossly exaggerated.
The
report includes a
recreational survey of existing lake and river recreational
opportunities in
the Yakima basin. These recreational opportunities are concentrated in
the
Cascade Mountains and have little in common with Black Reservoir which
would be
located in a treeless semi-arid area.
The recreation report indicates the annual visitor count
for the seven
lakes and five rivers in the Yakima basin survey at only 108,012. It is hard to conceive how
the construction
of an 8,640 acre lake in an area with summer temperatures climbing to
110
degrees would attract seven times the current number of visitors in the
study
area. The report foresees 245,000
annual fishing days per year. Black
Rock, as designed, would be deep and have steep slopes and virtually no
shallow
wetlands so critical to fish. We
believe
the potential for developing an attractive fishery in the reservoir are
very
small. The report forecasts 175,000
boat fishing visitor days and 175,000 water skiing and jet skiing
visitor
days. We believe
the lake is far too
small to support this number of boats, particularly when we take into
consideration that the lake surface will shrink as the irrigation
season
progresses. The
shrinking lake surface
and steep slopes will also leave boat launches and docks high and dry. The report and survey
ignores
other recreational facilities virtually on the doorstep of Black Rock
such as
the Hanford Reach, Lake Wallula, Priest Rapids Lake, Moses Lake, the
Columbia
National Wildlife Refuge, Scooteney Lake, Potholes reservoir and the
many parks
along the Lower Snake River. We already have an abundance of slake
water
reservoirs which are far from being over crowded. Desert Aire, a small
vacation
community located at Priest Rapids dam has struggled to survive for
many years
and has never attracted the visitors predicted for Black Rock. Electrical Supply Impacts: The draft EIS’s Table 4.12
portrays the costs and volume of electrical power required to pump
water into
Black Rock reservoir. The
electrical
costs are estimated to range from $33 to $93 million per year with an
average
of $50 million. The
report does not
indicate what price rate these estimates are based on.
We requested this information and were unable
to secure an answer. We
fear the rate is
a highly discounted bulk rate fare below that paid by residents,
businesses and
irrigators. Rate
information is a
critical component in determining the true costs of the pumping
operation and
must be available for public comment. The majority of the annual
pumping will be done in September and October, when Columbia and Yakima
River
flows are declining. The
table shows
that on average 511 MW and 430 MW will be required in September and
October
respectively. How
will this impact the
supply of electricity available to other consumers?
We must remember that the 396,847 acre feet
of water pumped out of the Columbia during September and October to
begin
refilling Black Rock will not be available to generate electricity at
Priest
Rapids dam or the four other dams downriver.
The market value of this foregone power generation should
be computed in
the actual cost of the project as well as the cost benefit ratio. How will the large
consumption
of power in September and October for pumping coupled with the
associated lost
power generation impact the supply of electricity?
Will this require BPA to buy expensive power
out of the area, driving up the rates paid by local consumers. Table 4.12 shows the average
annual power required to supply Black Rock at 132 MW.
The table also gives the average monthly
power required for each of the twelve months.
The total average MW for the twelve months listed on the
table is 1649
MW’s. How can the
sum of the monthly
averages be so many times higher than the annual average? It is hard to understand
how the table could
list the annual average at 132 MW when the monthly average for
September is 511
MW and 430 for October. Obviously
the
table is in error. The
table provides
critical information and should be corrected and included in a new
draft EIS
and submitted to public review. Cultural Impacts: We are concerned that
sufficient
research and field study has not been done on historic properties and
Native
American sacred sites. Table
ES.6 in the
draft EIS states under Historic Properties and Indian Sacred Sites
indicates
that the number of properties and sites is “unknown”.
This is unacceptable.
The presence of Sacred Sites can and rightly
should bring a multi billion dollar project to a screaming stop. The question of impacts to
historic and
sacred sites must be answered and provided in the draft EIS. Once again critical
information is missing
and a new draft EIS must be done and submitted for public review. Inadequacy of EIS: It should be noted that the
Bureau of Reclamation’s Yakima River Basin Reservoir and River
Recreation
Survey Report of Findings, Technical Series No TS-YSS-15 describes the
Yakima
River basin as encompassing Benton, Franklin, Yakima and Kittitas
counties. It should
be noted that
Franklin County is east of the Columbia River and not in the Yakima
Basin. Figure
4.11 on page 4-60 of the draft EIS portrays a map of the Yakima basin. The Figure erroneously
places the Horn Rapids
Irrigation Pump on the Columbia River and not its true location on the
Yakima
River. These are insignificant errors but they dampen our faith in the
accuracy
of the reports. In view of the lack of
information, pending reports and conflicting information contained in
the
study, we strongly recommend that the report be reviewed by an
independent body
of experts such as the National Academy of Science and a new draft EIS
be developed
and submitted for public review. Conclusion: We recommend that the Black
Rock
project be dropped from further consideration. The cost / benefit ratio of
.16
to 1 is totally unacceptable and renders the project financially
unsound. We
believe that when costs of foregone power generation due to water
diversions,
scaling back recreational benefits projections to a reasonable level
and the
costs of attempting to prevent ground water incursion onto the Hanford
Reservation are figured into the equation the cost / benefit ratio will
drop
far below the present .16 to 1 We believe the impacts to
migratory fish using the Hanford Reach alone make this project
unacceptable. Most importantly we believe
the
geological conditions at Black Rock coupled with the problem of ground
water
incursion on Hanford render the project unsafe.
We do not believe these conditions can be fixed or
mitigated. You can
not fix a fault line and we are
dealing with two fault lines on this project.
The threat of major earthquakes is high.
Horsethief Mountain, the critical right abutment of the
dam is very
unstable and prone to liquefaction which means we could completely
loose
Horsethief Mountain during an earthquake releasing the entire reservoir
in a
massive wave across Hanford. The
threat
of 30,000 or more acre feet of ground water per year pushing, building
and
forcing contaminated ground water under Hanford into the Columbia River
is also
unacceptable. In spite of all this, if the
decision is made to pursue the Black Rock project we recommend the
following: 1.
The current draft
EIS is unacceptable, it must be redone and reissued to the public for
comment 2.
Convene a group of
third party, disinterested experts, such as the National Academy of
Science to
thoroughly peer review the draft EIS. 3.
State and federal
legislation must be passed granting a water right to fish for the
440,000 acre
feet of water the project supposedly will leave in the Yakima River for
fish. The water
right should be held in
trust by the US Fish & Wildlife Service, US Marine Fisheries
Service and
Washington Department of Fish & Wildlife. 4.
Establish wetlands
to prevent the mixture of Columbia & Yakima River waters
entering the
Yakima River. 5.
Establish dikes,
flood gates and pumps to maintain shallow wetlands in the reservoir as
irrigation draws down the reservoir water level. 6.
Fully mitigate
impacts to the Hanford Reach by increasing Columbia River flows to
compensate
for water diverted to Black Rock. Alternatives: What would we propose doing
to
manage water in the Yakima basin if the Black Rock project were dropped? First of all the objective
of
Black Rock is not to expand irrigation in the lower Yakima valley but
to
increase Yakima River flows and provide a minimum of 70 % of the water
commitments in dry years – which have been found to be around 6 out of
every 25
years. We recommend studying the
possibility of diverting water out of the Yakima River during the high
spring
runoff into artificially constructed wetlands along the Yakima River. Allow these waters to
gradually seep into the
aquifer, storing them as ground water, far from Hanford. These waters could then be
tapped in dry
years by pumps managed by the Bureau of Reclamation.
Based on past history we would have 19 out of
every 25 years to build up our ground water supply and then only tap it
in dry
years by carefully managed wells. The wetlands created by
these
diversions would be extremely valuable to fish and wildlife and provide
recreational opportunities far superior to those envisioned at Black
Rock. This alternative would be
far
cheaper to construct and use only a fraction of the electrical power
Black Rock
would require. We also believe an insurance
or
subsidy system should be in place to compensate Yakima valley farmers
growing
annual crops thus enabling them to let their fields lay fallow during
drought
years while concentrating the available water on permanent crops such
as
orchards and vineyards. We also recommend pursuing
water
conservation and refitting irrigation systems to use the available
water as
effectively as possible. We believe these measures
could
provide the water needed by fish, wildlife, agriculture and urban
communities
in the right amount at the right time. Thank you for this
opportunity
to comment on these reports. We
appreciate the hard work you and your staff have done over many months
to
produce the report.
