Request for Water Quality Certification - Jordan Hydroelectric Project - 11437
To NC Clearinghouse and Div. of Environmental Management:
This letter requests water quality certification under Section 401 of the Clean
Water Act by the State of North Carolina for the Jordan Hydroelectric Project at Jor-
dan Dam in Chatham County. The environmental effects of this Project and its oper-
ating and construction features were reviewed by state agencies in a draft license
application in December 1995 and in a revision to that application in February 1996.
Based on the previous environmental review for this Project, we request that the
Clearinghouse issue an EA/FONSI so the Div. of Environmental Management can is-
sue a public notice and the certification.
The review number for this Project for the NC Clearinghouse is
96E000000409. The Project was reviewed in preliminary form by the NC state agen-
cies in late 1993 underthe item number 94E00000322.
Seven copies fo the application form for 401 Certification are attached. We
have included figures showing the planned construction. There will be no impact on
wetlands by the Project; there will not be any fill material. A 404 Permit is not neces-
sary. We have not sent a copy of this application to the Corps, because they have al-
ready reviewed the Project and provided comments.
Please call if there are any questions.

I think I already forwarded the materials I had on this one to
you. FERCt.in the past has prepared EAs after the applicant has
gone through the following 3 stage consultation process: 1)
Meeting/study plans 2) Draft license application 3) FERC issued
Public notice on the final license application. There is some
recent discussion on front-loading the NEPA process through an
applicant prepared EA. (We may go this way with Roanoke Rapids).
I called Jim Mead to see where we were with Jordan Hydro. He is
going to check the file, but he thinks we have not seen the
final license application yet. He will call me back to let me
know. I also suggested he/Steve Reed coordinate with you
regarding issues we may need to address in the 401 Certification.

Just talked to Chris Baggett. She said that there was no need
for EA/FONSI for this project since there is no public money or
state property. We got an application for 401 Certification on
28 February 1996. I'll proceed to do public notice for the 401
Certification. Please make copies of any and all comments and
I'll make sure that they are adequately dealt with. Thankx.
P.S. I copied Steve so he can learn the entire process for FERC
401s (i.e. public notices, etc.)!

Revised Draft of License Application - Jordan Hydroelectric Project - 11437
To the Party Addressed:
The draft license application for the Jordan Hydroelectric Project at Jordan
Dam in Chatham County, which you reviewed in December 1995, has been revised in
several aspects to respond to agency comments.
The following changes are incorporated in this revised draft from the draft re-
viewed in December: (a) the enlargement of the upper trash rack to avoid the intake
velocity exceeding 1.5 feet per second; (b) withdrawal of water from elevation 199
feet in the lake during the winter; (c) a 5.1 miles long transmission line of 23 kV
(street voltage) built, on roadside right-of-way, to the south.
Please call if there are any questions. With few exceptions the changes in the
draft are indicated by italics. Only the changed pages are forwarded. We expect this
to make it possible for your agency to complete the review quickly and request that
you provide a written response by February 16, 1996. A faxed response is fine or
timeliness, followed by a mailed hard copy. If we do not receive a response, we will
assume you have no further comments.
The review number for this Project for the NC Clearinghouse is
96E000000409.
The revisions to this draft do not introduce any new issues that must be re-
viewed; the departments in your agency that did not have comments previously
should not have comments on this revised draft.
Any comments you make will be forwarded to the FERC with our response. If
you feel a meeting is necessary to discuss the details and potential impacts, we will
be glad to meet with you.
Yours truly,

A.4) Primary Transmission Line
The primary transmission line will be a 23 KV line extending 5. 1 miles south
to the Moncure substation of Carolina Power and Light Co. The width will be 20
feet. The new right-of-way will be along existing road right-of-way for most of
its length.
A.5} Appurtenant Equipment
Control Building
Each generator will be switched at the generator voltage of 960 volts by
means of a circuit breaker located inside the control building. It is proposed to
utilize the generator breaker for all switching functions, synchronization and
isolation of the generator under short circuit conditions; this breaker will have
an adequate interruption rating. All generator breakers will be connected to a
common bus. The common bus will be connected to a single breaker located inside
the control building which will be connected to the control building substation.
The normal power supply for station services will be tapped from the common 960
volt generator bus through a fused disconnect switch and a 960/480 volt station
service transformer. A local feeder will he utilized as an alternative source of
power for station services.
Exhihit A Equipment page g
Project 11437
The control building is expected to be about 20 feet square; it will be in-
stalled on top of the intake tower or beside the intake tower on top of the dam.
Its design will be coordinated with the Corps of Engineers to ensure an aestheti-
cally satisfactory appearance and avoidance of interference with other activi-
ties.
Metering, relaying and supervisory controls necessary for a fully auto-
matic, remotely-controlled, unattended station will be provided.
Substation
The power generated at 960 V will be stepped up through: one or two three-
phase transformers to 23 kV, a 23 kV circuit breaker; and a visible disconnect
switch. The substation containing the step-up transformer, breaker and discon-
nect switch will he located on the intake tower or on the dam.
Two hoists will be installed on top of the intake tower to allow the modules
to be lowered into place in front of the tower intake chambers. Either one or two
motors will be used to lift the two modules as necessary. These hoists are shown
in Exhibit F. A truck-mounted hoist maybe used instead of & permanent hoist.
A.6) Lands of the United States
The Project is on lands owned by the Federal Government and managed by the
U. S. Army, Corps of Engineers, Wilmington District.
The total acreage of property for the Project including the transmission
line under the ownership of the U. S. Government is 3 acres. The rectangular por-
tion is 400' by 300 1; the linear portion along the transmission line is 25001 long
and 20 feet wide.
Exhibit E-4 Report on Historical and Archaeological Resources
Identified Sites
Archaeological and historical studies were conducted by the Corps of Engi-
neers in the planning and evaluation of impacts related to the construction of the
B. Everett Jordan Dam and Reservoir.
Physical remains of thousands of years of aboriginal cultures have been ob-
tained in hundreds of sites in the reservoir area. However, no archaeologically
sensitive sites have been found in the immediate vicinity of the project.
Impact of Project
There should be no new impacts to the local archaeological or historical re-
sources of the area, because no parts of the Project will be located in the immedi-
ate vicinity of any known sites.
There will be no construction outside of the existing structure of the dam,
there is no potential impact on historical or archaeological resources. The only
Project structures will be a service building that will be built in the disturbed
area near the dam.
The transmission line will require only the drilling of two 18 inch holes by
an auger for the placement of poles. The clearing for the transmission line will
not include any earth disturbing activities; only two acres must be cleared. The
line will extend 5.1 miles south with a width of 20 feet and will use roadside
right-of-way for all but 8500 feet of its length. See Exhibit G.
We do not believe an archaeological survey of the line route should be neces-
sary, because the only ground disturbance is boring holes for pole placement. The
route is over disturbed ground except for 8500 feet. We request that the State His-
toric Preservation Officer concur with no need for a survey.
If any cultural resources are discovered as a result of the construction of
the control building or any other part of the facility, the State Historic Preser-
vation Officer will be contacted.

Tailwater Rating Curve
Figure B.1 presents the tailwater rating curve.
Power plant Capability vs. Head
At a gross head of 49 feet the capacity is 8 MW; this is the normal expected
head. At the minimum expected gross head of 33 feet (reservoir elevation 202 feet
MSL) the capacity is 4. 6 MW.
Withdrawal of Water for Water Quality (Surface Release)
Water quality releases are presently made through the water quality gates.
The channel that the Project will install on the upstream face of the intake tower
will withdraw water from the same level in the lake as the water quality gates.
This similarity will be accomplished by taking water into the Channel at its top;
the top will be at elevation 211 feet MSL, which is the middle of the water quality
gate with its invert at elevation 207. This gate is the preferred one for withdraw-
als when the lake is near conservation pool (216 ft. MSL) . If the lake is lowered
more than four feet, the upper part of the Channel will be removed so the withdrawal
will be at elevation 207. If the lake is lowered further the Channel will be re-
moved so the withdrawal will be at elevation 199 feet MSL; this elevation will be
near the surface even at the bottom of the conservation pool.
If the lake level decreases below elevation 199 feet MSL, hydropower opera-
tion will cease and releases will be made from the water quality tower unless the
Corps determines that a bottom release through the intake chambers will not ad-
versely affect water quality.
If monitoring of water quality downstream indicates that more precision is
necessary in the withdrawal elevations to emulate the present withdrawal opera-
tion, the Channel will be modified by adding one or more sections to it, which can
be stacked to allow more variation in the withdrawal level. The stacked sections
can be removed one at a time to set the withdrawal elevation as necessary.
This additional precision should not be necessary, because the present water
quality gates cover eight feet of the water column when they are withdrawing. If
two gates are used, ten feet of the water column are adjacent to the open water
quality gates. The water quality operation is based on withdrawing water from as
near the surface as practical; this operating goal can be achieved using the
Channel.
The one change in present operation is the withdrawal level for releases be-
tween 500 cfs and 5000 cfs in the winter. This change is necessary so the large
upper trash rack is used and the intake velocity never exceeds 1.5 fps. At present
these flows (500 - 5000 cfs) are made using bottom withdrawal; with hydropower the
same flow as present will be withdrawn through the openings cut in the platform at
elevation 199 feet so the water will pass through the upper trash rack. The with-
drawal from elevation 199 feet instead of about 150 feet should not affect water
because the lake is isothermal during the winter.
In winter the majority of water will exit the lake from the bottom as it does
at present if the floe exceeds 5000 cfs; only 1150 cfs will be withdrawn from eleva-
tion 199 feet and pass through the turbines.
The flow patterns of the release will not change because the release will be
made through the service gates under all circumstances just as is done presently.
F,.xhihit B Project Operation
Project 11437
Page S
There is a backwater on the service gates; their discharge is under eight feet of
water. Dam releases will exit the stilling basin exactly as they do in present op-
eration.
The minimum release (or any other release) will be the same with the Project
operating. This is also true during Project installation. The modifications to
the intake tower are minimal and can be made with minor and short term (less than
one week) adjustments to operation. The holes that must be drilled on the platform
over the intakes can be made while releases are being made.
B.3) Power and Energy Utilization
The facility will be operated in a run-of-river mode, and power and energy
output will be determined by the Corps of Engineers' mandated releases. The power
dedicated to station load is expected to be negligible. The applicant anticipates
selling the entire annual output of 28 GWh to Carolina Power and Light Co.
B.4) Future Development Plans
This application does not propose the operation of the facility as a peaking
plant Any change in the operation to allow modified peaking would maintain all in-
stantaneous release requirements for water quality, such as the 600 cfs required
flow at Lillington gage. Any change from run-of-river operation would have to be
approved by the NC Division of Water and Wildlife Resources Commission and the
Corps of Engineers. A study of downstream aquatic habitat will determine the ef-
fect of any flow changes. If the potential environmental problems can be ad-
dressed, a peaking operation may be considered in the future.
Exhibit E-2 Water Quality Page 3
Project 11437
Measures to Maintain Water Quality During Project Operation
The hydroelectric Project will maintain the same level of withdrawal
through the design of the Channel in the summer period (May - November), when the
reservoir is stratified, as described in Exhibit B. The Project will have a with-
drawal scheme that emulates the level of withdrawal available through the existing
water quality gates. As described in Exhibits A and B, a half cylinder (Channel)
will be placed on the upstream face of the intake tower; the top of this half cylin-
der will be open to withdraw water from near the surface of the lake, just as the
water quality gates would do.
An upper section will have its top at elevation 211 feet MSL (5 feet below the
surface) to withdraw water from the upper part of the conservation pool. During a
drawdown for low flow augmentation the lake level will lower, the upper section of
the Channel can be removed and the top of the Channel will then be at 207 feet MSL.
If the lake level is lowered further, the lower section of the Channel will be re-
moved so the withdrawal occurs at elevation 199 feet MSL, which is the elevation of
the platform at the top of the passageway leading to the intake tower.
By implementing this design, the Channel will be operated to emulate the
withdrawal elevation that the Corps would establish using the water quality gates
in the intake tower. If necessary, more levels can be added to the Channel to add
more precision to the withdrawal level. This should not be necessary because when
the water quality gates in the tower are used the withdrawal zone covers 8 to 10
feet of the lake depth. This withdrawal zone should be duplicated by use of the
Channel.
During the winter the lake is isothermal, and it is not necessary to make
surface releases to pass oxygen rich water downstream for water quality purposes.
For this reason the Corps normally makes releases from the lake bottom in winter.
This is the one change that the Project will make in current operation. In the win-
ter releases between 500 cfs and 5000 cfs will be withdrawn from the lake at eleva-
tion 199 feet, the platform on top of the intake passage that will support the upper
trash rack. This change is necessary to pass the release through the trash rack,
which is large enough to keep the intake velocity at 1.5 feet per second or less.
There will be no change in downstream water qualitybecause the lake is isothermal
in winter, so the level of withdrawal is not critical to maintain water quality.
During flood releases (> 5000 cfs), water will be withdrawn from the bottom
of the lake into the passageways (chambers) upstream of the service gates except
that 1150 cfs of the release will pass through the turbines and will be withdrawn
from elevation 199 feet MSL. Releases below 500 cfs can be withdrawn from the lake
bottom and not exceed 1. 5 feet per second velocity at the lower trash rack.
Dissolved oxygen is the only water quality parameter that the Project could
impact. The applicant proposes to withdraw water from the same level in the lake
and in the same amount as the Corps does presently; this will maintain the water
quality for temperature and DO at the present level. The Project will not affect
the temperature of the release.

No endangered or threatened species inhabit the vicinity of the project with
the possible exception of the Bald Eagle, which might use it as a resting and feed-
ing area. Probably, red-cockaded woodpeckers no longer inhabit the area. The ab-
sence of any critical habitat near the Project means no endangered or threatened
species would be affected by the project.
Migration out of the Lake
Hybrid striped bass and largemouth bass probably pass through the intake
structure into the tailwater. The presence of hybrid striped bass below the dam
indicates that they migrate through the intake. This migration must occur either
from surface withdrawals in the summer (because the hypolimnion is anoxic) or win-
ter releases, which are made from the bottom of the reservoir. In the winter when
there is no stratification, fish are expected to be at all depths of the lake.
Near the outlet the lake is about 65 to 70 feet deep. It is probable that most of
the hybrid striped bass exit during high flow releases.
There is no reason to believe that other species are near the intake tower,
although they might be because the presence of the structure is an attracting fea-
ture. There is no evidence on the out migration of other species than hybrid
striped bass, because the other species occur naturally downstream.
Assessment of the Potential Impact of the Project
Impacts of the Transmission Line Right-of-Way
The 5.1 miles of transmission line should not have any impact on the local
environment, because all but 8500 feet will be built in the existing right-of-way
for local roads. As shown in Exhibit G, only 2 acres of the line passes through a
wooded area that must be cleared. The habitat area affected by the line is small
and is on the east side of the river downstream of the dam.
The vegetation in this area is upland pine forest as described above. It
provides limited habitat for small mammals because there is little cover. The
transmission line will not significantly impact wildlife habitat in the Project
vicinity because of its location and the small amount of clearing.

Proiect 11437
Impact on Fish
Page 4
The configuration of the proposed Project should avoid any adverse impact on
fish. Around the intake Channel screening will discourage or prevent entrance of
fish into the turbines during generating flows; the screen will avoid entrainment
and impingement. The larger (upper) screen (trash rack) will be sized to limit in-
take velocity to 1.5 feet per second (fps); it will have horizontal bar spacing of
less than 1. 5 inches. The low velocity and narrow bar spacing is expected to dis-
courage entrance into the trash rack by any fish that might want to exit the lake.
The criteria of this trash rack design to discourage entrance was proposed
by the NC WRC based on studies that indicate the swimming speed for most game and
forage fish is at least 2. 6 fps. The size of the fish in Jordan Lake makes it un-
likely that significant numbers of game or forage fish would be able to exit the
reservoir because of the horizontal bar spacing. We suspect, but there is no
proof, that the 80 turbines turning at 1800 rpm will generate enough sound similar
to outboard motors that fish would avoid the passages leading to the turbines.
Flow Regimes
The operation of the Project will ensure that all flow going to the turbines
will not exceed 1. 5 fps at the upper trash rack. This means the upper rack must be
used in the winter, as well as the summer, when the release exceeds 500 cfs (1. 5 fps
velocity on the lower rack). This should not adversely affect the water quality of
the release, because in winter the lake is isothermal.
Below 2320 cfs all water released will pass through the turbines. Between
2320 and 5000 cfs, flow in excess of 2320 cfs will pass into the intake tower
through the water quality gates; this will provide a bypass pathway for fish to
move around the turbines. At releases in excess of about 5000 cfs one of the tur-
bine modules will be lifted out the flow passages at the bottom of the intake
tower. Between 5000 and 10, 000 cfs only one module is in position; the unoccupied
intake passageway will be used for release as it is presently. This means for flows
greater than 5000 cfs, only 1150 cfs flows through the upper trash rack and into one
turbine module, and all other water (4 to 8 times as much) is spilled through the
passageway with its module in the raised position.
It is suspected that at higher flows, such as 5000 cfs and higher, most of
the out-migrating fish leave the lake, because those near the outlet tower could be
entrained in the high velocity of the release. For fish that exit at these high
flows (> 5000 cfs) the Project will have little or no impact, because the bypass
flow is sufficiently large that fish wishing to emigrate will be drawn to the by-
pass. There is no evidence at what time fish choose to migrate from the lake, but
other situations (such as John H. Kerr Lake) suggest that out migration of striped
bass (not hybrid) occurs at large flows following a spawning run.
For flows greater than about 10,000 cfs both modules will be lifted out of
the water passage; there will not prevent fish from emigrating downstream.
Screen (Trash Rack) Design
Screens will be installed at two locations to exclude trash and fish. The
upper screen will be used for surface withdrawals through the Channel; it was de-
scribed above. Lower screens in front of the turbine intakes will prevent trash
entrance and fish entrance when the flow is less than 660 cfs (velocity < 1. 5 fps) .
Fxhibit F-3 Fish and Wildlife Page S
Proieet 11437
The upper screen will have an open surface area of about 1550 square feet; it
will be 17 feet high on the right half and 19 feet high on the left. It will rest on
the platform at elevation 199 feet on the right side of the tower and at 197 feet
MSL on the left side. For a flow of 2320 cfs the velocity at the rack will be 1.5
feet per second. For 83$ of the time the flow does not exceed 2320 cfs. For 8$ of
the time the flow is between 2320 and 5000 cfs; 2320 cfs of the flow will pass
through the upper rack. In aummer the flow will also pass through the Channel; the
maximum flow through the Channel will be 2320 cfa. For 7$ of the time the flow is
between 5000 and 10, 000 cfs, the flow for generation is 1150 cfs.
The lower screen will be attached to the upstream entrance of the turbines
and have bar spacing of about 1.25 inches. Each of the two turbine modules is
about 20 feet high and 11 feet wide; the screens could be placed a few inches in
front of the turbine entrances and inclined so their surface area should be about
220 square feet. The total surface area of the lower screen should be more than
440 square feet. The lower screen will be a deterrent to entrance whether the
withdrawal is from the surface or the bottom of the lake. In winter for 30$ of the
time the velocity is less than 1. 5 feet per second.
The units will rotate at 1800 rpm. This high speed could cause mortality to
most of the fish passing through the turbines, because the probability of a strike
is high. The momentum of the turbine blades is small, because the blades are small
relative to normal turbine blades. The smaller momentum, because of the blades'
weight, would make a blade strike less damaging to any fish that is struck.
The high rpm should be a deterrent to fish entrance. This high rpm would
send out a high frequency acoustic wave that should deter fish from entering the
turbine in the same way that high frequency sound has been used with limited suc-
cess in deterring fish entrance. To a fish the turbines in the modules should sound
like a group of 80 outboard motors in a space about 20 feet by 20 feet. There is no
specific evidence to indicate the fish will avoid the trash rack area because of
the noise.
Summary of Project Aspects to Avoid Fish Mortality
Entrainment should not be a problem because of the small trash rack open-
ings. The WRC's evidence shows that at velocities of less than 1.5 fps and bar
spacing less than 2 inches, entrainment and impingement will not be a problem; see
their comments of January 4, 1996. The flow is always passed through a trash rack so
the entrance velocities are always 1.5 fps or less. For 83# of the time the veloc-
i ty is less than 1. 5 fps.
The screen spacing is smaller than suggested by WRC (1" to 1. 5" vs. 2") . The
fast rotational speed of the turbines might increase blade strikes, but the lower
momentum of the blades might reduce their effect on fish. The noise resulting from
the high rpm of the blades might discourage entrance.
Mitigation
Because the trash racks are designed to avoid mortality to fish no mitiga-
tion is necessary. If operational activity indicates that mortality is occurring,
the applicant will work with the WRC and other agencies to determine ways to avoid
the mortality. if this fails, we will work with the agencies to do compensatory
stocking in the lake to compensate for unavoidable mortality.
L'xhihit F,-3 Fish and Wildlife
Project 11437
Absence of Continuing Impacts
Page 6
The use of screens should avoid fish mortality from Project operation from
either impingement or entrainment.
The Project transmission line will not have a significant impact on wildlife
habitat or vegetation in the Project vicinity.
in general, there should be no impact on fish and wildlife because DO concen-
trations downstream are maintained and no temperature increases result from the
hydropower operation.
No endangered or threatened species would be affected by the project.
Exhibit E-6 Report on Land Management and Aesthetics
Existing Development and Land Use
The extent of use of project lands and existing development are limited to
the dam and related facilities and the maintenance of these facilities.
The lands directly contiguous to the dam are controlled by the U.S. Army,
Corps of Engineers, Wilmington District. The Corps controls the property to above
The spillway design flood (elev. 261.5 feet MSL) or about 45 feet above the normal
conservation pool level.
Aesthetic Factors
The applicant does not propose any structural modifications of the dam that
require any measures to assure that they blend with the surrounding environment.
The only features of the Project that will be visible to the public will be the fa-
cilities on top of the existing intake tower, the switchyard, a nearby service
building (about 20' x 20') and the transmission line. None of these minor struc-
tures will adversely impact the aesthetics of the area.
The transmission line will be routed beside roads for most of its length; it
will not pass through areas of significant public use, such as campgrounds or game
management areas.
Wetlands and Floodplains
There are no wetlands other than the lake and its coves within the vicinity
of the Project. Wetlands and marshlands are generally located much farther down-
stream on the Cape Fear River. Wetlands affected or created by the dam will not be
affected, because the Project will not change the release or the reservoir levels.
Wilderness and Wild and Scenic River Designations
No streams or rivers within the project boundary or in the vicinity are in-
cluded in or have been designated for study for inclusion in the National Wild and
Scenic Rivers System.
There are no areas within the vicinity of the project that, under the provi-
sions of the Wilderness Act, have been: (a) designated as wilderness area; (b) rec-
ommended for designation as wilderness area; or (c) designated as a wilderness
study area.
Land Use Along the Transmission Line Route
The transmission line will extend 5. 1 miles from the switchyard to the Mon-
cure substation of Carolina Power and Light Co. The line route will avoid anypub-
lic recreation areas and have no impact on land use in the Project vicinity. The
line route will use existing right-of-way for all but 8500 feet of its length. Only
2 acres must be cleared for the 20 feet wide right-of-way.
Response to Agency Comments
Response to Comments of the Corps of Engineers
The following responds to the Corps' letter of January 16, 1996 using par-
agraph labels.
a. The building is expected to be no more than 20 feet square. It will be
located as near the tower as possible. It could be on top of the tower. The trans-
mission line will cross the dam to the east, as shown in Exhibit G.
b. The trash rack is enlarged to avoid intake velocities greater than 1.5
feet per second (fps) in accordance with requirements of the NC WRY. This should
avoid impingement of any species or any need for compensatory stocking.
c. A model will be studied in coordination with the Corps consistent with
the requirements and information supplied.
d. No aeration is expected or previously observed. We believe this is
because the discharge under the gates enters a pool of water eight feet deep. At
smaller flows, for which water quality is important, there should be no aeration
because there is little or no air exposure of the discharge from turbulence. Moni-
toring downstream by the state will continue after operation begins; if any change
is noted, the applicant will respond as necessary. No change is expected for the
reasons mentioned.
e. The hoist may be replaced by a truck-mounted hoist, as used for sto-
plog placement. These details will be coordinated with the Corps during final de-
sign to ensure no structural problems. The hoist will be supported by a simple
frame structure that can be modified to place load on the tower at satisfactory lo-
cations. This design is subject to Corps' approval.
f. The applicant will be responsible for timely removal of the channel or
units. This should not be such a critical operation that it must be completed in
less than a few hours. operation will be coordinated and approved by the Corps
through a Memo of Agreement similar to that used at Colebrook Dam in CT. Operation
for power will be avoided if the lake is below 199 feet MSL unless the Corps deter-
mines water quality will not be affected.
g. The applicant will demonstrate to the Corps' satisfaction that the
gates can be operated for throttling before such operation is made. This operation
is desirable but not necessary for the success of the hydropower generation.
h. The feasibility of unbalanced flow will be verified by calculation or
modeling.
i. We calculate an annual energy of 28 GWh; this was done using actual
reservoir releases and elevations.
j . The draft is corrected.
k. Noted and appreciated.
Response to Comments of NC Wildlife Resources Commission (WRC)
The response to the NC WRC letter of January 4, 1996 refers to paragraph num-
bers on page 2 of that letter.
The significant unresolved issue raised by WRC is the intake velocity at the
trash rack and its potential for impinging fish on the rack if it exceeds 1.5 feet
per second (fps) . We have modified the Project to avoid a velocity in excess of 1.5
fps by enlarging the trash rack to have an area of 1550 feet square. For 83 percent
of the time the velocity will be less than 1.5 fps. We expect fish to avoid the area
near the rack because of the high frequency noise of the 80 turbines spinning at
1800 rpm; this should sound like 80 outboard motors to a fish.
Putting all flow through the upper (enlarged) trash rack will require with-
drawing water from elevation 199 feet in winter instead of the lake bottom at ele-
vation 150 feet MSL. This should have no impact on water quality, because the lake
is isothermal in winter. The changed withdrawal level in winter will only be nec-
essary for releases smaller than 5000 cfs. The majority of higher releases will
come from the bottom of the lake.
Based on information provided by WRC about fish swimming speeds, the small
trash rack velocity should avoid any danger that reservoir species will be im-
pinged on the rack. The small horizontal bar spacing (< 1. 5 inches) should prevent
fish entering the rack.
This larger rack meets WRC's criteria to avoid impingement and eliminates
the need for any other mitigation for fish mortality. Should mortality become evi-
dent during operation the applicant will work with the WRC and other agencies to
correct the mortality or provide compensatory stocking for unavoidable mortality.
Responses to other questions follow.
1. The inflatable bladders will prevent water from entering the tower for
release during the summer by blocking each of the two lower passageways downstream
of the existing trash racks. They will be tested to ensure proper operation during
installation. Should they fail, which is unlikely because of their simple and re-
liable construction, they will be replaced by a diver. They should not have any
problem fulfilling their function.
2. The installation will require alteration of releases for less than a
week. Release will not be stopped during construction.
3. The release will continue to be the same amount determined by the
Corps. If the Project cannot make any required release, the turbines can be by-
passed by the Corps to make releases just as they would presently.
4. Downstream studies and agency approval will precede any authorized
change in operation to pulsing or peaking.
The above comments also respond to the supportive comments made by the De-
partment of Environment, Health and Natural Resources on the Project. Their as-
sessment of the operation's lack of impact and its consistency with present opera-
tion is correct.
Response to Comments of U.S. F & Ws
The comments by the F& WS are similar to those of WRC, and those responses
apply. The service's conclusion that the Project's operation will avoid impacts
is correct.
The comments on the inflatable bladder are answered in the response to WRC Is
questions. The bladders should not fail; if they do, they will be replaced. Knowl-
edge of any failure, which is unlikely after installation, will occur from down-
stream temperature monitoring by the state.
If the Project is not making the correct releases according to its water
quality function, the Corps has the right and capability to bypass it until it is
corrected.
The main concern of the F& Ws is impingement of fish on the trash rack. The
larger rack now planned will avoid a velocity greater than 1.5 fps at any time. The
trash rack velocity will be less than 1.5 fps for 83% of the time. This small ve-
locity will avoid fish being impinged on the rack.
The Environmental Protection Agency did not have any comments on the Project
at this time.
We appreciate the supportive comments made by all the agencies in their re-
views. We believe they appreciated the beneficial aspects of the unusual Project
concept and its success in avoiding any significant environmental impacts.
