Duke Energy submits this new PCN for previously authorized impacts under the 2017 NWP No. 3 that expired on March 18, 2022. The work is within Section 10 Waters associated with
the installation of an Upstream Fish Passage at the Blewett Falls Hydroelectric Station in Lilesville, Anson County, North Carolina. The Fish Passage construction is a requirement of Duke
Energy's Yadkin -Pee Dee Hydro Project Operating License issued by the Federal Energy Regulatory Commission (FERC) Project No. 2206. The work had begun prior to the authorization
expiration date; however, the work will not be completed within 12 months from that date. We are requesting the authorizations be renewed to complete the remaining work.
The work remaining to be completed is associated with two separate NWP 3 authorizations:
1. SAW-2018-00568, dated 5/8/2019. The work remaining to be completed was described as "grading and placement of fill materials in 55 linear feet of stream to facilitate the installation
of a fish passage devise. This includes the installation of a temporary cofferdam..." in Section 10 waters. The cofferdam has been installed and the fish passage construction is
approximately 15% complete and is scheduled to be completed in 2024.
Two other projects were included in the authorization. Under NWP 12 the overhead powerlines were relocated over Section 10 waters to facilitate the fish passage installation, this work
has been completed. The third project was under NWP 3 to install a cofferdam in Section 404 waters to facilitate the installation of inflatable spillway gates. The cofferdam was not
necessary for the gate replacement.
2. SAW-2018-00568, dated 8/23/2021. This project was authorized under NWP 3 and is ongoing. The project is associated with the fish passage and is for the construction of a work
platform trestle in Section 10 waters. The trestle will be removed after the fish passage is completed in 2024.

SAW-2018-00568
Dear Mr. Bailey:
Duke Energy submits this new PCN for previously authorized impacts under the 2017 NWP No.
3 that expired on March 18, 2022. The work is within Section 10 Waters associated with the
installation of an Upstream Fish Passage at the Blewett Falls Hydroelectric Station in Lilesville,
Anson County, North Carolina. The Fish Passage construction is a requirement of Duke
Energy's Yadkin -Pee Dee Hydro Project Operating License issued by the Federal Energy
Regulatory Commission (FERC) Project No. 2206.
The work had begun prior to the authorization expiration date; however, the work will not be
completed within 12 months from that date. We are requesting the authorizations be renewed
to complete the remaining work.
The work remaining to be completed is associated with two separate NWP 3 authorizations:
1. SAW-2018-000568, dated 5/8/2019. The work remaining to be completed was
described as "grading and placement of fill materials in 55 linear feet of stream to
facilitate the installation of a fish passage devise. This includes the installation of a
temporary cofferdam..." in Section 10 waters. The cofferdam has been installed and the
fish passage construction is approximately 15% complete and is scheduled to be
completed in 2024.
Two other projects were included in the authorization. Under NWP 12 the overhead
powerlines were relocated over Section 10 waters to facilitate the fish passage
installation, this work has been completed. The third project was under NWP 3 to install
a cofferdam in Section 404 waters to facilitate the installation of inflatable spillway gates.
The cofferdam was not necessary for the gate replacement.
2. SAW-2018-000568, dated 8/23/2021. This project was authorized under NWP 3 and is
ongoing. The project is associated with the fish passage and is for the construction of a
work platform trestle in Section 10 waters. The trestle will be removed after the fish
passage is completed in 2024.
We have informally consulted with Mr. Fritz Rohde with the National Marine Fisheries Service
(NMFS) on the need for further consultations with NMFS for renewal of the NWP 3. Mr. Fritz
stated in an email (dated 8/16/2021) to you for the 8/23/2021 trestle authorization that there is
no need for further consultation because the Resource Management Team (RMT) had
approved the proposed modification. Mr. Fritz is on extended leave, and we have reached out

to Ms. Twyla Cheatwood and Mr. Andy Herndon with NMFS for confirmation that further
consultation with NMFS is not needed. When we receive confirmation, we will forward it to you.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Due to the Projects being a requirement of Duke Energy's Yadkin -Pee Dee Hydro Project Operating License issued by the Federal Energy Regulatory
Commission (FERC) Project No. 2206 the project could not be avoided. The fish passage and work platform are the minimum size necessary.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Consideration will be taken as the fish passage design is finalized to to keep the impact to a minimum. The fish passage flume entrance within the tail
race must meet certain design criteria to attract the targeted species. The work platform trestle is a temporary structure that will be removed when the
project is completed.

Sent: Monday, September 26, 2022 4:04 PM
To: Ronald Haden Walker
Subject: Automatic reply: [External] 401/Buffer Pre -filing Meeting Request
This message originated outside of S&ME. Please report this as phishing if it implies it is from an S&ME employee.
This email confirms receipt of your pre -filing meeting request. Please retain this email for your records and
submit this documentation as part of your 401 application (PCN Application) as required by federal law. DWR
will not be able to accept your application without this federally required documentation. 401 applications
received without documentation that a pre -filing meeting request was submitted at least 30 days prior will be
returned as incomplete.
Responses to this email are not monitored.
Background
On April 6, 2022, the United States Supreme Court issued an order staying a lower court's vacatur of the
Trump Administration's 2020 "Clean Water Act Section 401 Certification Rule" ("Federal Rule"). As a result of
the United States Supreme Court order, the Trump Administration's Federal Rule has sprung back into effect.
The Trump Administration's Federal Rule imposes additional procedural requirements on applicants for 401
Certifications and on DWR's processing of those applications. One requirement is that 401 applicants must
request a pre -filing meeting request at least 30 days prior to submitting their 401 application. [40 C.F.R.
§121.4] In turn, the Federal Rule requires that applicants include documentation of their pre -filing meeting
request in their 401 Certification application. [40 C.F.R §121.1; 40 C.F.R. §121.5]. Please refer to the Federal
Rule for more information.
Per 40 CFR §121 and §121.5, a 401 Certification application that does not include the required pre -filing
meeting request documentation does not constitute a "certification request." As a result of the reinstatement
of the Trump Administration's Federal Rule, all 401 applications received after April 6, 2022 that do not have
documentation that a pre -filing meeting request was submitted at least 30 days prior to submittal of a 401
Certification application will be returned as incomplete.

Construction of a cofferdam to
install a fish passage device
Consultation History
NMFS's Revised Biological Opinion (Opinion) for the Yadkin -Pee Dee Hydroelectric Project
(YPDHP) issued on April 17, 2015,1 required the installation of a fish passage device for the
upstream passage of American Shad. The Opinion for YPDHP covered the construction of the fish
passage but did not consider installation of a cofferdam and related effects to species and related
critical habitat.
We received your letter requesting consultation for the installation of the cofferdam on September
19, 2018. Due to recent findings to ESA -listed sturgeon species and required work windows, we
requested additional information regarding the proposed action's construction conditions on
November 8 and December 17, 2018. We received a final response on December 19, 2018, and
initiated consultation that day. Consultation was held in abeyance for 38 days due to a lapse in
appropriations and resulting partial government shutdown. Consultation resumed on January 28,
2019. This project was originally assigned a tracking number (SER-2018-19586) in our now
obsolete tracking system. The project has been assigned a tracking number in our new NMFS
Environmental Consultation Organizer (ECO), SERO-2018-00255. Please refer to this number in
any future inquiries regarding this project.

Existing Site Conditions
The project is located on the Pee Dee River at the Blewett Falls Dam and Hydroelectric Station in
Lilesville, Anson County, North Carolina, at approximately river mile 188.2 from the nearest
opening to the Atlantic Ocean at Winyah Bay. The site includes the Blewett Falls Lake Dam,
retaining wall, and concrete tailrace. According to United States Army Corps of Engineers
(USACE), dominant substrate within the project include scoured bedrock, intermittent boulders and
large cobble. Water quality is typically good and consistently meets North Carolina water quality
standards for dissolved oxygen. Water depth in the project area ranges from approximately 4 to 18
feet (ft), with an average depth estimated at 10 ft.
2

Blewett Falls Dam represents the Pee Dee River system's upstream extent of sturgeon spawning and
summer/winter seasonal habitat. The fall line (the boundary between an upland region of continental
bedrock and an alluvial coastal plain, sometimes characterized by waterfalls or rapids) is located
approximately 22 river miles below Blewett Falls Dam.
Project Description
The applicant proposes to install a cofferdam around the upstream fish passage facilities required by
the YPDHP for American shad. All construction activities of the fish passage facility will be
conducted once the installation of the cofferdam is complete and the area dewatered. The dewatered
area of the cofferdam will be approximately 2,900 square feet (ft2) (0.07 acres [ac]).
Data obtained from 3 geotechnical borings will be used to determine the final design of the
cofferdam that will be used to dewater the work area for installation of the fish passage facility. The
borings will be performed using an ATV/track-mounted drill rig atop a spud barge deployed in the
tailrace. The 4-in-diameter borings will be extended to depths ranging from 25 to 45 ft below the
river bottom. Upon completion of the project, the borings will be backfilled "from the bottom up"
with cement grout placed via a tremie pipe. The cofferdam is expected to be constructed of braced
sheet pile.
The approximate total length of sheet pile cofferdam is 245 ft. It is anticipated that approximately
105 PZ 35 (or similar) type sheet piles (approximately 28-in-wide) will be used for the cofferdam.
The sheet piles will be installed using a vibratory hammer deployed via a land -based crane with a
clamshell bucket. A bubble curtain system will be deployed around active pile driving to attenuate
noise from pile driving. Equipment mounted on the spud barge in the tailrace will guide the
placement of the sheet piles. The interior side of the sheet pile wall will be braced with steel
framework as needed depending on the embedment depth achieved by the piles. Depending on the
embedment depth of the piles, a tremie concrete seal may need to be placed along the exterior
perimeter of the sheet pile wall. Once the sheet pile cofferdam is installed and dewatered, the
concrete retaining wall that forms the shoreline of the tailrace and is inside the cofferdam will be
demolished and removed from the site. When the construction of the new fish passage facility is
complete, the cofferdam will be removed the same way it was installed.

Construction Conditions
No in -water work in the river on the downstream side of Blewett Falls Dam and within 500 yards
(yd) of the dam or power station may occur from February 1 to April 30 or September 15 to October
15 of any year. This does not apply to emergency work (i.e., work that cannot wait until after the
time restriction). The cofferdam will be installed and boring activities conducted during the period
when in -water work is allowable per the terms of the YPDHP Opinion and periods allowable under
the terms of the 404 Permit. This would include periods of the in -water work prohibition periods
specified in the Opinion and described above. The cofferdam will remain in place for the duration of

construction, which is expected to take up to one year. Tailrace borings will occur once the 404
Permit is received.
NMFS's Revised Opinion covers the fish passage construction and operation, and Reasonable and
Prudent Measure (RPMs) are contained in the BiOp with implementing Terms and Conditions
(T&Cs). Therefore, the applicant will implement these protective measures as required by RPM#1
and T&C#1 to protect sturgeon during fish passage construction activities. RPM #1 and T&C#1
specify that all potential adverse impacts to sturgeon during the construction and operations of the
TST fish passage facility (a trap, sort and truck facility in the Blewett Falls tailrace, which would be
used to collect anadromous species [primarily American shad] so that they could be sorted and then
transported, via truck, to areas upstream of Blewett Falls) or during other construction activities or
maintenance of the Blewett Falls Dam are to be minimized to the greatest extent practicable.
The applicant has agreed to adhere to NMFS's Sea Turtle and Smalltooth Sawfish Construction
Conditions.3 If a sturgeon is seen within 100 yd of the active daily construction/maintenance
operation, all appropriate precautions shall be implemented to ensure its protection. Operation of any
moving mechanical construction equipment shall cease immediately if a sturgeon is seen within a 50-
ft radius of the equipment. Activities may not resume until the protected species has departed the
project area of its own volition. Additionally, turbidity curtains will be used for all in -water work.
Appropriate erosion and turbidity controls (e.g. cofferdam) shall be utilized during any in -water work
carried out by the applicant to limit contaminant -laden sediments from entering the water. No
construction debris shall be allowed to enter the water.

Critical Habitat
The project is located in Atlantic sturgeon critical habitat Carolina Unit 5 (Pee Dee Unit). Based on
the project's location within the river system, approximately 188 river miles upstream from the
mouth of the Pee Dee River, we believe adults, subadults, juveniles, and larval sturgeon may be
present in the vicinity of the proposed action.
The Physical and Biological Features (PBFs) of the critical habitat are described in the table below.
We believe the proposed action may affect PBF 1, hard substrate; PBF 3, unobstructed water of
appropriate depth; and PBF 4, water quality. The project is located in freshwater habitat; therefore,
PBF 2 is not present within the action area.

Analysis of Potential Routes of Effects to Species
Effects to Atlantic and shortnose sturgeon may include the risk of injury or death from interactions
with construction activities and/or equipment; however, we believe this scenario is discountable due
to the species' mobility. The applicant's implementation of NMFS's Sea Turtle and Smalltooth
Sawfish Construction Conditions will further reduce the risk of interactions by requiring all
construction workers to watch for sturgeon. Operation of all mechanical construction equipment will
5

cease immediately if a sturgeon is seen within a 50-ft radius of the equipment. Activities will not
resume until the protected species has departed the project area of its own volition.
Use of turbidity curtains, the construction activities, and related construction noise may prevent or
deter sturgeon from entering the project area. We believe that the effect to sturgeon from temporary
exclusion from the project area due to construction activities, including related noise and presence of
turbidity curtains, will be insignificant. The size of the area from which sturgon will be excluded is
relatively small in comparison to the available river habitat, which sturgeon will be able to use during
construction. After project completion, turbidity curtains will be removed and sturgeon will be able
to return to the project area.
Sturgeon could be affected by the placement of temporary in -water structures (e.g., cofferdams) in
areas that may serve as spawning habitat. We believe the effect to sturgeon from the placement of
temporary in -water structures will be insignificant. The area of temporary impact is relatively small
(2,900 ft2 [0.07 ac]) compared to the surrounding area available that will serve as spawning habitat
for the sturgeon. Further, once the temporary structure is removed, sturgeon can use the area for
spawning again.
Sturgeon may be affected by the permanent loss of habitat due to the placement of pile -supported
structures. However, the effect to sturgeon from the potential loss of spawning habitat due to the
placement of pile -supported structures is insignificant. Sturgeon are a mobile species that spawn
over large areas and the area of impact is relatively small (420 ft2 [0.001 ac]) compared to the
surrounding river habitat available.
Effects to listed species as a result of noise created by construction activities can physically injure
animals or change animal behavior in the affected areas. Injurious effects can occur in two ways.
First, immediate adverse effects can occur to listed species if a single noise event exceeds the
threshold for direct physical injury. Second, effects can result from prolonged exposure to noise
levels that exceed the daily cumulative exposure threshold for the animals, and these can constitute
adverse effects if animals are exposed to the noise levels for sufficient periods. Behavioral effects
can be adverse if such effects interfere with animals migrating, feeding, resting, or reproducing, for
example. Our evaluation of effects to listed species as a result of noise created by construction
activities is based on the analysis prepared in support of the Opinion for SAJ-82.3 The noise analysis
in this consultation evaluates effects to ESA -listed fish species identified by NIVIFS as potentially
affected in the table above.
The current NMFS-accepted noise thresholds to ESA -listed fish species due to vibratory hammer
driving are 206 decibels (dB) for peak -pressure injury, 234 dB for cumulative sound exposure level
(cSEL) injury, 150 dB root mean square (RMS) for behavioral disturbance of fishes over 102 grams
(g) in weight. We do not expect fish under 102 g in weight to be present because the location is
approximately 188 river miles from the mouth of the river and sufficiently far from the upstream
spawning locations (pers. comm., A. Herndon and F. Innocenti on 12/20/2018). The applicant will
install all piles using a vibratory hammer to drive 28-in-wide steel sheet piles to depth. Additionally,
our calculation is based on 1 sheet pile installed at the maximum allowance of vibration time in a 12-
hour period (i.e., number of seconds [sec] of vibration per pile x number of piles per day = estimated
NMFS. Biological Opinion on Regional General Permit SAJ-82 (SAJ-2007-01590), Florida Keys, Monroe
County, Florida. June 10, 2014.

number of sec per day [43,200 = 60 sec x 60 minutes x 12 hours]) all construction activities will
occur during daylight hours only. To minimize potential noise impacts, the applicant will use air
bubble curtains to reduce noise levels. According to the best available data,4 air bubble curtains
provide a 5 dB reduction in vibratory hammer underwater sound levels to piles up to 24 in wide.4
Based on our noise calculations, installation of 28-in steel sheet piles by vibratory hammer using air
bubble curtains for noise abatement will not cause single -strike or peak -pressure injury to ESA -listed
fish species. The cSEL of multiple sheet piles over the course of a 24 hour period may cause injury
to ESA -listed fishes radius of up to 0.47 ft (0.14 m). Due to the mobility of ESA -listed fish species,
we expect them to move away from noise disturbances. Because we anticipate the animal will move
away, we believe that an animal's suffering physical injury from noise is extremely unlikely to occur.
Even in the unlikely event an animal does not vacate the daily cumulative injurious impact zone, the
radius if that area is smaller than the 50-ft radius that will be visually monitored for sturgeon.
Construction personnel will cease construction activities if animal sturgeon is sighted per NMFS's
Sea Turtle and Smalltooth Sawfish Construction Conditions. Thus, we believe the likelihood of any
injurious cSEL effects is discountable. An animal's movement away from the injurious impact zone
is a behavioral response, with the same effects discussed below.
Based on our noise calculations, installation of 24-in sheet piles by vibratory hammer using air
bubble curtains as noise abatement could result in behavioral effects at radii of up to 152 ft (46 m) for
ESA -listed fishes. Given the mobility of sturgeon, we expect them to move away from noise
disturbances. Because there is similar river habitat nearby, we believe this effect will be
insignificant. Since installation will occur only during the day, these species will be able to resume
normal activities during quiet periods between pile installations and at night. Additionally, based on
the configuration of the project area, sturgeon will be able to depart the affected area through several
pathways; no access route will be blocked. Therefore, we anticipate any potential behavioral effects
will be insignificant.
Analysis of Potential Routes of Effect to Critical Habitat
Hard substrate necessary for the settlement of fertilized eggs and refuge, growth, and development of
early life stages (PBF 1) may be affected by the installation of piles. However, we believe this effect
will be insignificant. The river contains gravel and cobble that may serve as a critical function for
egg, larvae, and adult sturgeon growth and spawning; however, the temporary cofferdam piles will
only affect a small portion of the tailrace. The available substrate surrounding the permanent and
temporary structures will continue to support these early life stages, and once the temporary structure
is removed, these areas of hard substrate will become accessible again. According to the USACE,
the applicant will not conduct any in -water work from February 1 to April 30 and from September 15
to October 15 of any year, to prevent any interruption of sturgeon spawning and migration.
The unobstructed water of appropriate depth (PBF 3) may be affected by the proposed action;
however, we believe the effect will be insignificant. For the life stages potentially using the action
area, PBF 3 refers to water that is free from obstruction such that: spawning adults can make
unencumbered movements to the spawning grounds; adults can access staging, resting, and holding
habitats; and juveniles can make seasonal and physiologically -dependent movements to appropriate
salinity zones within the river. It also refers to the requirement that the main channel to be deep
enough to ensure that there is continuous flow when adults or juveniles are there. The project will

not alter the depth of the main channel or water flow in the channel. The installation of turbidity
curtains, air bubble curtains, and a temporary cofferdam will only affect a small portion of the
tailrace. These structures will be removed following completion of the fish passage facility. Upon
removal, these structures will no longer create an obstruction to sturgeon movement. The installation
of the cofferdam may create noise that could deter the movement of sturgeon through the area.
However, no in -water pile driving will be allowed from February 1 to April 30 and from September
15 to October 15 of any year, to prevent any disruption of adult sturgeon migration activities.
Therefore, we believe any effects to PBF3 will be insignificant.
Localized and temporary reductions in water quality (PBF 4) through increased turbidity may result
from the temporary placement of the cofferdam. We believe the effect to PBF 4 from localized and
temporary increased turbidity will be insignificant because turbidity curtains will be used to contain
turbidity and we expect any small amount of turbidity that may escape to have an insignificant effect
on the water quality conditions, especially in the bottom meter of the water column, with appropriate
temperature and oxygen values.
Conclusion
Because all potential project effects to listed species and critical habitat were found to be
discountable, insignificant, or beneficial, we conclude that the proposed action is not likely to
adversely affect listed species and critical habitat under NMFS's purview. This concludes your
consultation responsibilities under the ESA for species under NMFS's purview. Consultation must
be reinitiated if a take occurs or new information reveals effects of the action not previously
considered, or if the identified action is subsequently modified in a manner that causes an effect to
the listed species or critical habitat in a manner or to an extent not previously considered, or if a new
species is listed or critical habitat designated that may be affected by the identified action. NMFS's
findings on the project's potential effects are based on the project description in this response. Any
changes to the proposed action may negate the findings of this consultation and may require
reinitiation of consultation with NMFS.
We look forward to further cooperation with you on other projects to ensure the conservation of our
threatened and endangered marine species and designated critical habitat. If you have any questions
on this consultation, please contact Francesca Innocenti, Consultation Biologist, at [phone],

1) The Corps of Engineers believes that there may be jurisdictional aquatic resources in the review
area, and the requestor of this PJD is hereby advised of his or her option to request and obtain an
approved JD (AJD) for that review area based on an informed decision after having discussed the
various types of JDs and their characteristics and circumstances when they may be appropriate.
2) In any circumstance where a permit applicant obtains an individual permit, or a Nationwide General
Permit (NWP) or other general permit verification requiring "pre- construction notification" (PCN), or
requests verification for a non -reporting NWP or other general permit, and the permit applicant has
not requested an AJD for the activity, the permit applicant is hereby made aware that: (1) the permit
applicant has elected to seek a permit authorization based on a PJD, which does not make an official
determination of jurisdictional aquatic resources; (2) the applicant has the option to request an AJD
before accepting the terms and conditions of the permit authorization, and that basing a permit
authorization on an AJD could possibly result in less compensatory mitigation being required or
different special conditions; (3) the applicant has the right to request an individual permit rather than
accepting the terms and conditions of the NWP or other general permit authorization; (4) the applicant
can accept a permit authorization and thereby agree to comply with all the terms and conditions of that
permit, including whatever mitigation requirements the Corps has determined to be necessary; (5)
undertaking any activity in reliance upon the subject permit authorization without requesting an AJD
constitutes the applicant's acceptance of the use of the PJD; (6) accepting a permit authorization (e.g.,
signing a proffered individual permit) or undertaking any activity in reliance on any form of Corps
permit authorization based on a PJD constitutes agreement that all aquatic resources in the review area
affected in any way by that activity will be treated as jurisdictional, and waives any challenge to such
jurisdiction in any administrative or judicial compliance or enforcement action, or in any
administrative appeal or in any Federal court; and (7) whether the applicant elects to use either an AJD
or a PJD, the JD will be processed as soon as practicable. Further, an AJD, a proffered individual
permit (and all terms and conditions contained therein), or individual permit denial can be
administratively appealed pursuant to 33 C.F.R. Part 331. If, during an administrative appeal, it
becomes appropriate to make an official determination whether geographic jurisdiction exists over
aquatic resources in the review area, or to provide an official delineation of jurisdictional aquatic
resources in the review area, the Corps will provide an AJD to accomplish that result, as soon as is
practicable. This PJD finds that there "may be" waters of the U.S. and/or that there "may be"
navigable waters of the U.S. on the subject review area, and identifies all aquatic features in the
review area that could be affected by the proposed activity, based on the following information:

Construction of a cofferdam to
install a fish passage device
Consultation History
NMFS's Revised Biological Opinion (Opinion) for the Yadkin -Pee Dee Hydroelectric Project
(YPDHP) issued on April 17, 2015,1 required the installation of a fish passage device for the
upstream passage of American Shad. The Opinion for YPDHP covered the construction of the fish
passage but did not consider installation of a cofferdam and related effects to species and related
critical habitat.
We received your letter requesting consultation for the installation of the cofferdam on September
19, 2018. Due to recent findings to ESA -listed sturgeon species and required work windows, we
requested additional information regarding the proposed action's construction conditions on
November 8 and December 17, 2018. We received a final response on December 19, 2018, and
initiated consultation that day. Consultation was held in abeyance for 38 days due to a lapse in
appropriations and resulting partial government shutdown. Consultation resumed on January 28,
2019. This project was originally assigned a tracking number (SER-2018-19586) in our now
obsolete tracking system. The project has been assigned a tracking number in our new NMFS
Environmental Consultation Organizer (ECO), SERO-2018-00255. Please refer to this number in
any future inquiries regarding this project.

Existing Site Conditions
The project is located on the Pee Dee River at the Blewett Falls Dam and Hydroelectric Station in
Lilesville, Anson County, North Carolina, at approximately river mile 188.2 from the nearest
opening to the Atlantic Ocean at Winyah Bay. The site includes the Blewett Falls Lake Dam,
retaining wall, and concrete tailrace. According to United States Army Corps of Engineers
(USACE), dominant substrate within the project include scoured bedrock, intermittent boulders and
large cobble. Water quality is typically good and consistently meets North Carolina water quality
standards for dissolved oxygen. Water depth in the project area ranges from approximately 4 to 18
feet (ft), with an average depth estimated at 10 ft.

Blewett Falls Dam represents the Pee Dee River system's upstream extent of sturgeon spawning and
summer/winter seasonal habitat. The fall line (the boundary between an upland region of continental
bedrock and an alluvial coastal plain, sometimes characterized by waterfalls or rapids) is located
approximately 22 river miles below Blewett Falls Dam.
Project Description
The applicant proposes to install a cofferdam around the upstream fish passage facilities required by
the YPDHP for American shad. All construction activities of the fish passage facility will be
conducted once the installation of the cofferdam is complete and the area dewatered. The dewatered
area of the cofferdam will be approximately 2,900 square feet (ft2) (0.07 acres [ac]).
Data obtained from 3 geotechnical borings will be used to determine the final design of the
cofferdam that will be used to dewater the work area for installation of the fish passage facility. The
borings will be performed using an ATV/track-mounted drill rig atop a spud barge deployed in the
tailrace. The 4-in-diameter borings will be extended to depths ranging from 25 to 45 ft below the
river bottom. Upon completion of the project, the borings will be backfilled "from the bottom up"
with cement grout placed via a tremie pipe. The cofferdam is expected to be constructed of braced
sheet pile.
The approximate total length of sheet pile cofferdam is 245 ft. It is anticipated that approximately
105 PZ 35 (or similar) type sheet piles (approximately 28-in-wide) will be used for the cofferdam.
The sheet piles will be installed using a vibratory hammer deployed via a land -based crane with a
clamshell bucket. A bubble curtain system will be deployed around active pile driving to attenuate
noise from pile driving. Equipment mounted on the spud barge in the tailrace will guide the
placement of the sheet piles. The interior side of the sheet pile wall will be braced with steel
framework as needed depending on the embedment depth achieved by the piles. Depending on the
embedment depth of the piles, a tremie concrete seal may need to be placed along the exterior
perimeter of the sheet pile wall. Once the sheet pile cofferdam is installed and dewatered, the
concrete retaining wall that forms the shoreline of the tailrace and is inside the cofferdam will be
demolished and removed from the site. When the construction of the new fish passage facility is
complete, the cofferdam will be removed the same way it was installed.

Construction Conditions
No in -water work in the river on the downstream side of Blewett Falls Dam and within 500 yards
(yd) of the dam or power station may occur from February 1 to April 30 or September 15 to October
15 of any year. This does not apply to emergency work (i.e., work that cannot wait until after the
time restriction). The cofferdam will be installed and boring activities conducted during the period
when in -water work is allowable per the terms of the YPDHP Opinion and periods allowable under
the terms of the 404 Permit. This would include periods of the in -water work prohibition periods
specified in the Opinion and described above. The cofferdam will remain in place for the duration of

construction, which is expected to take up to one year. Tailrace borings will occur once the 404
Permit is received.
NMFS's Revised Opinion covers the fish passage construction and operation, and Reasonable and
Prudent Measure (RPMs) are contained in the BiOp with implementing Terms and Conditions
(T&Cs). Therefore, the applicant will implement these protective measures as required by RPM#1
and T&C#1 to protect sturgeon during fish passage construction activities. RPM #1 and T&C#1
specify that all potential adverse impacts to sturgeon during the construction and operations of the
TST fish passage facility (a trap, sort and truck facility in the Blewett Falls tailrace, which would be
used to collect anadromous species [primarily American shad] so that they could be sorted and then
transported, via truck, to areas upstream of Blewett Falls) or during other construction activities or
maintenance of the Blewett Falls Dam are to be minimized to the greatest extent practicable.
The applicant has agreed to adhere to NMFS's Sea Turtle and Smalltooth Sawfish Construction
Conditions.3 If a sturgeon is seen within 100 yd of the active daily construction/maintenance
operation, all appropriate precautions shall be implemented to ensure its protection. Operation of any
moving mechanical construction equipment shall cease immediately if a sturgeon is seen within a 50-
ft radius of the equipment. Activities may not resume until the protected species has departed the
project area of its own volition. Additionally, turbidity curtains will be used for all in -water work.
Appropriate erosion and turbidity controls (e.g. cofferdam) shall be utilized during any in -water work
carried out by the applicant to limit contaminant -laden sediments from entering the water. No
construction debris shall be allowed to enter the water.

Critical Habitat
The project is located in Atlantic sturgeon critical habitat Carolina Unit 5 (Pee Dee Unit). Based on
the project's location within the river system, approximately 188 river miles upstream from the
mouth of the Pee Dee River, we believe adults, subadults, juveniles, and larval sturgeon may be
present in the vicinity of the proposed action.
The Physical and Biological Features (PBFs) of the critical habitat are described in the table below.
We believe the proposed action may affect PBF 1, hard substrate; PBF 3, unobstructed water of
appropriate depth; and PBF 4, water quality. The project is located in freshwater habitat; therefore,
PBF 2 is not present within the action area.

Analysis of Potential Routes of Effects to Species
Effects to Atlantic and shortnose sturgeon may include the risk of injury or death from interactions
with construction activities and/or equipment; however, we believe this scenario is discountable due
to the species' mobility. The applicant's implementation of NMFS's Sea Turtle and Smalltooth
Sawfish Construction Conditions will further reduce the risk of interactions by requiring all
construction workers to watch for sturgeon. Operation of all mechanical construction equipment will
5

cease immediately if a sturgeon is seen within a 50-ft radius of the equipment. Activities will not
resume until the protected species has departed the project area of its own volition.
Use of turbidity curtains, the construction activities, and related construction noise may prevent or
deter sturgeon from entering the project area. We believe that the effect to sturgeon from temporary
exclusion from the project area due to construction activities, including related noise and presence of
turbidity curtains, will be insignificant. The size of the area from which sturgon will be excluded is
relatively small in comparison to the available river habitat, which sturgeon will be able to use during
construction. After project completion, turbidity curtains will be removed and sturgeon will be able
to return to the project area.
Sturgeon could be affected by the placement of temporary in -water structures (e.g., cofferdams) in
areas that may serve as spawning habitat. We believe the effect to sturgeon from the placement of
temporary in -water structures will be insignificant. The area of temporary impact is relatively small
(2,900 ft2 [0.07 ac]) compared to the surrounding area available that will serve as spawning habitat
for the sturgeon. Further, once the temporary structure is removed, sturgeon can use the area for
spawning again.
Sturgeon may be affected by the permanent loss of habitat due to the placement of pile -supported
structures. However, the effect to sturgeon from the potential loss of spawning habitat due to the
placement of pile -supported structures is insignificant. Sturgeon are a mobile species that spawn
over large areas and the area of impact is relatively small (420 ft2 [0.001 ac]) compared to the
surrounding river habitat available.
Effects to listed species as a result of noise created by construction activities can physically injure
animals or change animal behavior in the affected areas. Injurious effects can occur in two ways.
First, immediate adverse effects can occur to listed species if a single noise event exceeds the
threshold for direct physical injury. Second, effects can result from prolonged exposure to noise
levels that exceed the daily cumulative exposure threshold for the animals, and these can constitute
adverse effects if animals are exposed to the noise levels for sufficient periods. Behavioral effects
can be adverse if such effects interfere with animals migrating, feeding, resting, or reproducing, for
example. Our evaluation of effects to listed species as a result of noise created by construction
activities is based on the analysis prepared in support of the Opinion for SAJ-82.3 The noise analysis
in this consultation evaluates effects to ESA -listed fish species identified by NIVIFS as potentially
affected in the table above.
The current NMFS-accepted noise thresholds to ESA -listed fish species due to vibratory hammer
driving are 206 decibels (dB) for peak -pressure injury, 234 dB for cumulative sound exposure level
(cSEL) injury, 150 dB root mean square (RMS) for behavioral disturbance of fishes over 102 grams
(g) in weight. We do not expect fish under 102 g in weight to be present because the location is
approximately 188 river miles from the mouth of the river and sufficiently far from the upstream
spawning locations (pers. comm., A. Herndon and F. Innocenti on 12/20/2018). The applicant will
install all piles using a vibratory hammer to drive 28-in-wide steel sheet piles to depth. Additionally,
our calculation is based on 1 sheet pile installed at the maximum allowance of vibration time in a 12-
hour period (i.e., number of seconds [sec] of vibration per pile x number of piles per day = estimated

number of sec per day [43,200 = 60 sec x 60 minutes x 12 hours]) all construction activities will
occur during daylight hours only. To minimize potential noise impacts, the applicant will use air
bubble curtains to reduce noise levels. According to the best available data,4 air bubble curtains
provide a 5 dB reduction in vibratory hammer underwater sound levels to piles up to 24 in wide.4
Based on our noise calculations, installation of 28-in steel sheet piles by vibratory hammer using air
bubble curtains for noise abatement will not cause single -strike or peak -pressure injury to ESA -listed
fish species. The cSEL of multiple sheet piles over the course of a 24 hour period may cause injury
to ESA -listed fishes radius of up to 0.47 ft (0.14 m). Due to the mobility of ESA -listed fish species,
we expect them to move away from noise disturbances. Because we anticipate the animal will move
away, we believe that an animal's suffering physical injury from noise is extremely unlikely to occur.
Even in the unlikely event an animal does not vacate the daily cumulative injurious impact zone, the
radius if that area is smaller than the 50-ft radius that will be visually monitored for sturgeon.
Construction personnel will cease construction activities if animal sturgeon is sighted per NMFS's
Sea Turtle and Smalltooth Sawfish Construction Conditions. Thus, we believe the likelihood of any
injurious cSEL effects is discountable. An animal's movement away from the injurious impact zone
is a behavioral response, with the same effects discussed below.
Based on our noise calculations, installation of 24-in sheet piles by vibratory hammer using air
bubble curtains as noise abatement could result in behavioral effects at radii of up to 152 ft (46 m) for
ESA -listed fishes. Given the mobility of sturgeon, we expect them to move away from noise
disturbances. Because there is similar river habitat nearby, we believe this effect will be
insignificant. Since installation will occur only during the day, these species will be able to resume
normal activities during quiet periods between pile installations and at night. Additionally, based on
the configuration of the project area, sturgeon will be able to depart the affected area through several
pathways; no access route will be blocked. Therefore, we anticipate any potential behavioral effects
will be insignificant.
Analysis of Potential Routes of Effect to Critical Habitat
Hard substrate necessary for the settlement of fertilized eggs and refuge, growth, and development of
early life stages (PBF 1) may be affected by the installation of piles. However, we believe this effect
will be insignificant. The river contains gravel and cobble that may serve as a critical function for
egg, larvae, and adult sturgeon growth and spawning; however, the temporary cofferdam piles will
only affect a small portion of the tailrace. The available substrate surrounding the permanent and
temporary structures will continue to support these early life stages, and once the temporary structure
is removed, these areas of hard substrate will become accessible again. According to the USACE,
the applicant will not conduct any in -water work from February 1 to April 30 and from September 15
to October 15 of any year, to prevent any interruption of sturgeon spawning and migration.
The unobstructed water of appropriate depth (PBF 3) may be affected by the proposed action;
however, we believe the effect will be insignificant. For the life stages potentially using the action
area, PBF 3 refers to water that is free from obstruction such that: spawning adults can make
unencumbered movements to the spawning grounds; adults can access staging, resting, and holding
habitats; and juveniles can make seasonal and physiologically -dependent movements to appropriate
salinity zones within the river. It also refers to the requirement that the main channel to be deep
enough to ensure that there is continuous flow when adults or juveniles are there. The project will

not alter the depth of the main channel or water flow in the channel. The installation of turbidity
curtains, air bubble curtains, and a temporary cofferdam will only affect a small portion of the
tailrace. These structures will be removed following completion of the fish passage facility. Upon
removal, these structures will no longer create an obstruction to sturgeon movement. The installation
of the cofferdam may create noise that could deter the movement of sturgeon through the area.
However, no in -water pile driving will be allowed from February 1 to April 30 and from September
15 to October 15 of any year, to prevent any disruption of adult sturgeon migration activities.
Therefore, we believe any effects to PBF3 will be insignificant.
Localized and temporary reductions in water quality (PBF 4) through increased turbidity may result
from the temporary placement of the cofferdam. We believe the effect to PBF 4 from localized and
temporary increased turbidity will be insignificant because turbidity curtains will be used to contain
turbidity and we expect any small amount of turbidity that may escape to have an insignificant effect
on the water quality conditions, especially in the bottom meter of the water column, with appropriate
temperature and oxygen values.
Conclusion
Because all potential project effects to listed species and critical habitat were found to be
discountable, insignificant, or beneficial, we conclude that the proposed action is not likely to
adversely affect listed species and critical habitat under NMFS's purview. This concludes your
consultation responsibilities under the ESA for species under NMFS's purview. Consultation must
be reinitiated if a take occurs or new information reveals effects of the action not previously
considered, or if the identified action is subsequently modified in a manner that causes an effect to
the listed species or critical habitat in a manner or to an extent not previously considered, or if a new
species is listed or critical habitat designated that may be affected by the identified action. NMFS's
findings on the project's potential effects are based on the project description in this response. Any
changes to the proposed action may negate the findings of this consultation and may require
reinitiation of consultation with NMFS.
We look forward to further cooperation with you on other projects to ensure the conservation of our
threatened and endangered marine species and designated critical habitat. If you have any questions
on this consultation, please contact Francesca Innocenti, Consultation Biologist, at [phone],
or by email at [e-mail].

Re: Blewett Falls Powerhouse Modification, Yadkin -Pee Dee Hydroelectric Project, FERC 2206,
Multi County, ER 01-8094
Dear Ms. Churchill:
Thank you for your letter of January 22, 2018, regarding the above -referenced undertaking. We have reviewed
your submittal and offer the following comments.
As proposed, there will be no adverse effect to the Blewett Falls Lake Dam (AN0024) which was determined
eligible for listing in the National Register of Historic Places in 2006. However, we recommend that you
contact us for technical assistance should you decide to change the outward appearance of the new concrete
retaining wall sections.
There are no known archaeological sites within the proposed project area. Based on our knowledge of the
area, it is unlikely that any archaeological resources that may be eligible for inclusion in the National Register of
Historic Places will be affected by the project. We, therefore, recommend that no archaeological investigation
be conducted in connection with this project.
The above comments are made pursuant to Section 106 and 110 of the National Historic Preservation Act and
the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106 codified at 36
CFR Part 800.
Thank you for your cooperation and consideration. If you have questions concerning the above comment,
contact Renee Gledhill -Earley, environmental review coordinator, at 919-814-6579 or
[e-mail]. In all future communication concerning this project, please cite the above
referenced tracking number.
