4. Project Description and History
4a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application:*
The proposed Project site is an undeveloped upland area approximately 2.3 acres in size located north of the Rogers Energy Complex (Complex), Formerly known as Cliffside Steam
Station in Cleveland, North Carolina (Figure 1). Specifically, the site is located adjacent to the low head dam and along the northern bank of the Broad River. The area has been previously
used by Duke Energy as laydown space for activities associated with the Complex. Vegetation within this area is comprised of grasses and forbs. The Project site is surrounded by
undeveloped forested and open land, gravel roads, and utility rights -of -way. Land use in the vicinity of the Project is industrial, agricultural, rural residential land, and undeveloped forested
and open land (Figure 2).
4b. Have Corps permits or DWR certifications been obtained for this project (including all prior phases) in the past? *
Yes No Unknown
4f. List the total estimated acreage of all existing wetlands on the property:
0
4g. List the total estimated linear feet of all existing streams on the property:
150
4h. Explain the purpose of the proposed project: *
The Cliffside Low Head Dam — Laydown Area Project in Cleveland, North Carolina has been sited to support Duke Energy's contractor during maintenance construction activities at the
Cliffside low head dam. The work area is proposed for a staging, laydown, and barge launch during the installation of anchors and bulkhead modifications within the Broad River (Stream
1) and across from the Complex.
4i. Describe the overall project in detail, including indirect impacts and the type of equipment to be used: *
The Project proposes to construct a 50 x 50-foot barge pad and associated ramp to support construction activities for the low head dam. Duke Energy's contractor will utilize equipment,
including a crane, mounted on a barge to access the low head dam in order to provide a dry working surface. The barge will help to manage the existing river flow in order to access areas
of the dam for the anchor installation. The ramp will result in permanent fill impacts of approximately 150 feet of along the bank of Stream 1 (Figure 3). In addition, the barge will also be
utilized to install 60-foot of temporary sheet piles within the dam and to 5 H-piles within the Broad River as part of the contractor's mooring plan and to help tie -off equipment for a safe
working environment (see Cliffside ESC 20211004). To support this equipment and access, the proposed laydown area is necessary for the storage and phasing of materials for this
construction. As such, erosion and sediment control plans are attached to this application and provide a summary of the work, including best management practices. Due to the small work
area proposed and absence of grading/earthwork, proposed erosion and sediment control measures for this project include a construction entrance, perimeter compost filter socks, a stone
barge launch, and a concrete wash out within the existing Duke Energy facility. The project is located within the Broad River Basin due to the nature of dam modification work; however,
there are no surface water features within the proposed limits of disturbance of the laydown area. Note that there will be no change in impervious surface area from pre -to post -
development conditions.

E. Impact Justification and Mitigation
1. Avoidance and Minimization
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
Prior to the proposed laydown and barge launch area being finalized, an alternate location was evaluated (area adjacent to the intake and within the
Cliffside facility). Due to the proximity of this area to other active facility construction projects and because of safety concerns, this option was not
feasible. The second available option for the Project's site was to utilize a Duke Energy owned property across the Broad River with similar access to the
low head dam, which in addition provides good clearance to the stream bank.
After the Project site was selected the laydown area and barge launch areas were designed to avoid and minimize impacts. Dredging of the stream has
been avoided and fill impacts to Stream 1 have been minimized to the greater extent possible. The proposed work at this location will only include minor
permanent impacts to the stream's shoreline, and the placement of temporary sheet piles.
Pre-existing contours will be restored, and disturbed areas will be stabilized sequentially as construction proceeds within the proposed limits of
disturbance. Access improvement, including the clearing of trees, will take place within the proposed limits of disturbance as well.
During the construction phases, the laydown areas will be monitored weekly and inspected after storm events to assess the condition of best
management practices and progress of stabilization of areas, as needed. Upon completion of the anchor and bulkhead installations, all project areas will
be stabilized. The proposed barge ramp will be left in place given the likelihood of future projects requiring river access for dam safety and other Duke
Energy facility inspections and projects.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Impacts to the river will be minimized during barge landing construction. Access will be through uplands, via adjacent roadways. Best Management
Practices will be used during construction activities.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State?
Yes No
2b. If this project DOES NOT require Compensatory Mitigation, explain why:
Proposed impacts will not exceed 150 feet of the Stream 1 northern bank along the water's edge and will not extend grater than two feet below the OHWM.
F. Stormwater Management and Diffuse Flow Plan (required by DWR)
