Project Description
3a.
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 Project Area and immediate surroundings are composed of maintained right-of-way and pastureland.
3b.
List the total estimated acreage of all existing wetlands on the property:
No wetlands were identified on the property.
3c.
List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
One perennial stream (tributary to the Little Tennessee River) totaling approximately 600 linear feet is located on the
property.
3d.
Explain the purpose of the proposed project:
Duke Energy proposes to install a 45 -foot -long, 10 -foot 11 -inch wide by 4 -foot 3 -inch height box culvert to allow for
maintenance equipment access to the existing transmission line towers.
3e.
Describe the overall project in detail, including the type of equipment to be used:
The culverts were sized to accommodate a 10 -year storm event without overtopping the driveway. The culverts will be
installed approximately 1 foot below the existing stream bed at a slope that allows for passage of water and movement of
aquatic
life. The project will be constructed in the dry and will result in permanent impacts associated with the CMPs and
temporary
impacts associated with de -watering for the pump around, impervious dikes, the stabilized outlet section, and the
sediment removal device. Standard construction equipment will be used, such as excavators, backhoes, hauling trucks, etc.

Impact Justification and Mitigation
1.
Avoidance and Minimization
Ia.
Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The box culvert length and sizes were selected to minimize impacts to impacts to jurisdictional waters. The culvertwill
be installed approximately 1 foot below the existing stream bed at a slope that allows for passage of water and movement
of aquatic life. Stream bed material (i.e., cobbles/gravels) will be placed in the culverts to mimic natural instream
conditions.
b.
Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The project will be constructed in the dry and surrounding construction area will be stabilized via sediment and erosion
control devices. Disturbed stream banks will be sloped back, seeded with native vegetation, and malted with
biodegradable erosion control material. -

5d. What data sources did you use to determine whether your site would impact Endangered Species or Designated
Critical Habitat? -
HDR consulted the USFWS'sCritical Habitat GIS shapefiles and N.C. Natural Heritage Program's (NCNHP)
Element Occurrence database for protected species distribution and proximity to the Project Area. The USFWS's
database revealed that there is active critical habitat for the spotfin chub (Erimonax monachus) and the NCNHP's
database confirmed known occurrences of sensitive species in the Little Tennessee River immediately downstream
of the Project Area. No critical habitats, known occurrences, or habitat for the remaining federally protected species
are located within the Project Area.
Correspondence (July 28, 2016) was sent to the USFWS requesting comments on any possible issues that may
emerge with respect to endangered species, migratory birds, or other resources from the proposed construction
activities. To date, no response has been received from the USFWS; however, when a response is received, it will
be forwarded promptly to the USACE.
6. Essential Fish Habitat (Corps Requirement)
6a. Will this project occur in or near an area designated as essential fish habitat?

7a. Will this project occur in or near an area that the stale, federal or tribal
governments have designated as having historic or cultural preservation
Yes ®No
status (e.g., National Historic Trust designation or properties significant in
North Carolina history and archaeology)?
7b. What data sources did you use to determine whether your site would impact historic or archeological resources?
HDR reviewed the National Park Service National Register of Historic Places (NRNP) GIS Public Dataset and the
N.C. Historic Preservation Office (NCHPO) HPOWEB GIS Web Service. The review revealed there are no known
cultural resources, historic structures, or historic districts located within the Project area (Figure 4). Archaeological
data were not included as part of the NCHPO GIS services and were not assessed as part of this study.
Correspondence (dated July 28, 2016) was sent to the NCHPO requesting information on historic/cultural
resources that may be impacted by the proposed project. To date, no response has been received from the
NCHPO; however, when a response is received, it will be forwarded promptly to the USACE.

Good morning,
The discrepancy in length is that the initial PCN proposed two 48 -inch CMP's that were 52 -feet in length versus the newly
proposed box culvert that spans 45 -feet. The tributary is relatively straight in this section and sinuously is not anticipated
to factor into the impact length of the culvert. Below is a revised stream impacts table from the PCN application detailing
temporary and permanent impacts to the tributary (also attached).

Tim,
Okay... that is what I was wondering. We have notification that UPS delivered three full sets (11x17) of the project this
morning to your office. That set should show:
1) A revised plan showing the culvert
2) Details/section and notes showing the culvert is buried 1' -
I need to double check the disturbance. The culvert is 45', but I want to make sure that the centerline measurement of the
stream is not 52'...that might be the discrepancy. Eric Mularski, who prepared the environmental package, is out of the
office till tomorrow.
Thanks,

Robert,
Thank you for sending the new design detail. Appreciate the quick response and the re -design.
Can you clarify the new length of impact for the new design? Detail says 45 ft? or will it be 52 ft?
Can you also provide a detail showing how the new design will meet the aquatic passage requirement.
Placement of culverts and other structures in waters and streams must be below the
elevation of the streambed by one foot for all culverts with a diameter greater than 48 inches;
and 20percent,of the culvert diameter foreuiveM having a d iameter less than oreq, pl to 48
inches, to allow lbw flow passage of water and aquatlo life.
Lastly, can you provide an updated plan view sheet OOOC-01 with the new design feature.
Thanks,
Tim

Mr. Fox,
Good morning. We are in receipt of the attached letter requesting additional information. The design of the dual culverts
has been modified to incorporate a 10'-11"(span) x 4'-3"(rise) structural plate culvert buried one foot (attached detail). We
can send three sets of the fully modified plans, but was wondering if they can be 11x17 or if you need full size.
Thank you,
Robert
