Subject: Cowans Ford Floating Bulkhead Ramp and Storage Project
Lincoln County, North Carolina
Dear Mr. Johnson:
I am writing on behalf of Duke Energy Carolinas, LLC (Duke Energy) in reference to Division of
Water Resources ID Number 20200340, Cowans Ford Floating Bulkhead Ramp and Storage
Project, which was verified by Mr. Alan Johnson of the Division of Water Resources in March 2020
(See Attachment 1). Duke Energy proposed to install a launch ramp for a floating bulkhead that will
be used for dam inspections for the nearby Cowans Ford Hydroelectric Station. Duke Energy
received verification of the Nationwide Permit 36 on March 16, 2020 (SAW-2020-00448),
authorizing permanent impacts of 0.14 acre (See Attachment 2) and the approval of 401 Water
Quality Certification on March 18, 2020. A portion of this work is already completed, the rip rap and
crushed stone base has been installed and a portion of the concrete slab was installed on top.
Duke Energy and their construction contractor, Crowder Construction Company (Crowder),
originally proposed to install the ramp via a causeway. Crowder proposed to pour the concrete
slabs onshore and then push/pull them into place. During the construction process, this method
proved not to be feasible. The construction plan was redesigned with a proposed cofferdam
system, provided by Portadam. This method will allow construction to be completed in the dry and
ensure design compliance for the ramp. (See Attachment 3 — Portadam Example for a simplified
example of the installation.) Please note, the de -watering of the work area will not be discharged
directly into the lake.
The construction sequence will be as follows:
• Crowder will install rock past the end of the existing ramp (see Attachment 4 — Revised
Impact Figure for additional details).
• The cofferdam framework will be preassembled on land, placed in the water using a forklift
or excavator, floated to the desired location, and rested on the bottom.
• Once in the desired location, heavy-duty netting will be installed on the framework, and
then the liner will be floated out and installed over the netting and framework.
• Once the liner is installed, the work area will be de -watered.
• De -watering will be accomplished with two to three pumps placed inside spill containments
onshore (see Attachment 5 — De -watering Plan for additional details):
o Rip rap will be placed onshore in an upland area for the pump discharge.
o Once the water reaches lower levels, 4-inch pumps will be utilized with sediment
bags before discharge onshore. The water from the temporary workspace will be
run through sediment bags and then allowed to infiltrate in the upland area or
return via overland flow to the lake.
o Pumps will be used to keep the work area dry.

Page 2
Once the area is de -watered, the launch ramp construction will be completed, by installing
the concrete slabs.
Once construction is finished, water will be pumped back into the de -watered area.
The liner will be removed, the netting will be removed, and finally the framework will be
removed and moved onshore.
The newly proposed permanent impacts will result from the placement of rip rap at the end of the
ramp to facilitate the cofferdam installation. The rip rap will result in approximately 0.02 acre (56
cubic yards) of additional permanent impacts. Total permanent impacts are 0.16 acre (1,513.4 cubic
yards) for original and newly proposed work. The de -watered workspace area will result in
approximately 0.18 acre of temporary impacts.
If you have any questions or require additional information after your review of the enclosed
materials, please contact me at [phone] or Anthony.Nardoa-hdrinc.com.

Subject: APPROVAL of 401 Water Quality Certification with Additional Conditions
Cowans Ford Boat Ramp
Dear Mr. Arcella:
You have our approval, in accordance with the General Certification and those
conditions listed below, for the purpose proposed in your application dated March 4, 2020, and
received by the Division of Water Resources (the Division) on March 5, 2020. After reviewing
your application, we have determined that this project is covered by Water Quality General
Certification Number 4132 and/or 4145 which can be viewed on our web site at
https://deg. nc.gov/about/divisions/water-resources/water-resources-permits/wastewater-
branch/401-wetlands-buffer-permits/401-401-isolated-wetlands-waters-program The General
Certification allows you to use Nationwide Permit Number 36 and/or Regional General Permit
30 once it is issued to you by the U.S. Army Corps of Engineers (COE). Please note that you
should get any other federal, state or local permits before proceeding with your project,
including those required by (but not limited to) Sediment and Erosion Control, Non -Discharge,
and Water Supply Watershed regulations.
The above noted Certification will expire when the associated 404 permit expires unless
otherwise specified in the General Certification. It is advised that all conditions of the
Certification are reviewed prior to initiation of the project. In addition to the requirements of the
Certification, you must also comply with the following conditions:
This approval is only valid for the purpose and design that you described in your
application. If you change your project, you must notify us in writing, and you may be
required to send us a new application for a new Certification. If total wetland fills for this
project (now or in the future) exceed one acre, or of total impacts to streams (now or in
the future) exceed 300 linear feet, compensatory mitigation may be required. If the
property is sold, the new owner must be given a copy of the Certification and approval
letter; and is thereby responsible for complying with all conditions. 15A NCAC
02H .0506 and 15A NCAC 02H .0507
2. The Mooresville Regional Office shall be notified in writing once construction at the
approved impact areas has commenced. 15A NCAC 02H .0502 (e)

this certification, any violation of stream or wetland standards [including but not limited to
sediment impacts, and any violation of state regulated riparian buffer rules. Information
shall be provided orally within 24 hours (or the next business day if a weekend or
holiday) from the time the applicant became aware of the circumstances. A written
submission shall also be provided within 5 business days of the time the applicant
becomes aware of the circumstances. The written submission shall contain a description
of the noncompliance, and its causes; the period of noncompliance, including exact
dates and times, if the noncompliance has not been corrected, the anticipated time
compliance is expected to continue; and steps taken or planned to reduce, eliminate,
and prevent reoccurrence of the noncompliance. The Division may waive the written
submission requirement on a case -by -case basis. 15A NCAC 02B .0200

This Certification can be contested as provided in Articles 3 and 4 of the General Statute
150B by filing a written petition for an administrative hearing to the Office of the Administrative
Hearings (hereby known as OAH). A petition form may be obtained from the OAH at

De-Waterine Plan - Cowan's Ford Bulkhead Ra
Two to three pumps (minimum of 4") to be used to remove water inside cofferdam. Pumps to be
positioned uphill of cofferdam, leveled, and placed inside spill containments. Suction hose with attached
suction screens to be set in strategic locations inside cofferdam. Rip Rap to be placed on lake bank for
discharge point. Discharge hose will be running to where the water will be discharged onshore onto rip
rap to keep water turbulence to a minimum. As the water level lowers, pumps can be moved further
down inside cofferdam. Once water conditions warrant, 4" pumps can be used with sediment bags to
reduce sediment levels prior to discharging onshore. The sediment bags can be placed on or near rip
ra p.
Please note -sediment bags can only be used with 4" pumps to avoid blowing out bags. See attached
diagram for additional information.
Once water is reduced to a desired level- multiple small diameter electric pumps placed in sumps can be
used to maintain any cofferdam water leaks.
Rain for Rent cannot guarantee a timeline for water removal —unknown water intrusions with
cofferdam installation can exist.
