Subject: Nationwide Permit 12 / General Water Quality Certification No. 3884 Approval
Duke Energy - Moss-Dowdle Mountain Access Culvert Project
Macon County, North Carolina
To Whom It May Concern:
Duke Energy Carolinas, LLC (Duke Energy) is submitting a Pre -Construction Notification (PCN) application
for Section 404/401 approval through the U.S. Army Corps of Engineers (USACE) Nationwide Permit
(NWP) 12 and N.C. Division of Water Resources (NCDWR) Water Quality Certification (WQC) No. 3884
for construction activities associated with a permanent culvert installation on a tributary to the Little
Tennessee River for the Moss-Dowdle Mountain Transmission Line Project in Macon County (Figures 1
and 2).
Project Overview
Duke Energy proposes to install two 52 -foot -long, 48 -inch -diameter corrugated metal pipes (CMPs)
below the Ordinary High Water Mark (OHWM) of a tributary to the Little Tennessee River at the Moss-
Dowdle property to allow for maintenance equipment access to the existing transmission line towers
(Figure 3). The Project Area and immediate surroundings are composed of maintained right-of-way and
pastureland (attached photographs). As part of the proposed installation, a hydraulic analysis was
performed that considered the historic flows and the existing stream gradient, drainage area, and soils
to appropriately size culverts 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. Stream bed material (i.e., cobbles/gravels) will be
placed in the culverts to mimic natural instream conditions. The project will be constructed in the dry
and will result in approximately 52 linear feet of permanent impacts associated with the CMPs, and 85
linear feet of temporary impacts associated with de -watering for the pump around, impervious dikes,
the stabilized outlet section, and the sediment removal device. Table 1 provides a summary of
jurisdictional stream impacts identified on the attached project plans.

The proposed construction area will be stabilized via sediment and erosion control measures, which will
be installed and employed prior to construction. These devices will be inspected and maintained
throughout the duration of the project to protect water quality and aquatic habitat. Disturbed stream
banks will be sloped back, seeded with native vegetation, and matted with biodegradable erosion
control material.
The NWP Regional Conditions do not require compensatory mitigation for permanent stream impacts
less than 150 linear feet. Therefore, no mitigation payments are proposed.
Agency Correspondence
Cultural Resources
HDR reviewed the National Park Service National Register of Historic Places (NRHP) 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.
Federally Protected Species
HDR obtained an updated species lists for Macon County from the U.S. Fish and Wildlife Service's
(USFWS) website (https://www.fws.gov/raleigh/species/cntylist/macon.html), which was last updated
on July 24, 2015. Table 2 represents the species under federal protection in Macon County provides a
summary of these species.

E = Endangered. A taxon "in danger of extinction throughout all or a significant portion of its range."
T = Threatened. A taxon "likely to become endangered within the foreseeable future throughout all or a significant portion of its range."
T(S/A) = Threatened due to similarity of appearance. A taxon that is threatened due to similarity of appearance with another listed species
and is listed for protection. Taxa listed as T(S/A) are not biologically endangered or threatened and are not subject to Section 7 consultation.
Current = The species has been observed in the county within the last 50 years.
Probable/Potential = the species is considered likely to occur in this county based on the proximity of known records (in adjacent counties),
the presence of potentially suitable habitat, or both.
HDR consulted the USFWS's Critical 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 (Figure 5).
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.
Trout Waters
Macon County is a designated county with "Trout Waters". A copy of the PCN application will be
submitted to the N.C. Wildlife Resources Commission (NCWRC) to assess potential impacts to trout
waters.

We are hereby requesting authorization to construct the proposed Project under a Section 404 NWP 12
and Section 401 WQC No. 3884. If you have any questions or require additional information after your
review of the enclosed information, please contact me at [phone] or William.Metcalfe@duke-

5. Endangered Species and Designated Critical Habitat (Corps Requirement)
5a. Will this project occur in or near an area with federally protected species or
® Yes ❑ No
habitat?
5b. Have you checked with the USFWS concerning Endangered Species Act
® Yes ❑ No
impacts?
❑ Raleigh
5c. If yes, indicate the USFWS Field Office you have contacted.
® Asheville
5d. What data sources did you use to determine whether your site would impact Endangered Species or Designated
Critical Habitat?
HDR consulted the USFWS's Critical 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?
❑ Yes ® No
6b. What data sources did you use to determine whether your site would impact Essential Fish Habitat?
7. Historic or Prehistoric Cultural Resources (Corps Requirement)
7a. Will this project occur in or near an area that the state, 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 (NRHP) 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.

10. STABILIZE 2:1 SLOPES WITH CLASS 1 RIP -RAP ON LAYER OF NON -WOVEN GEOTEXTILE
FABRIC (15' DEPTH).
11. STABILIZE ALL EXPOSED AREAS, AND REMOVE EROSION CONTROL MEASURES AND PERFORM
FINAL SITE RESTORATION.
MAINTENANCE PLAN
THE MAINTENANCE PLAN SHALL BE FOLLOWED UNTIL THE SITE IS STABILIZED. MAINTENANCE OF
SEDIMENT AND EROSION CONTROL MEASURES WILL BE PERFORMED BY A SUBCONTRACTOR.
1. ALL SEDIMENT AND EROSION CONTROL DEVICES AND PLANTED AREAS SHALL BE INSPECTED
EVERY SEVEN (7) CALENDAR DAYS AND AFTER EACH RAINFALL OCCURRENCE THAT EXCEEDS
ONE-HALF (1/2 ) INCH WITHIN A 24-HOUR PERIOD. DAMAGED OR INEFFECTIVE DEVICES
SHALL BE REPAIRED OR REPLACED, AS NECESSARY, AS SOON AS PRACTICAL
2. ALL TEMPORARY CONTROL DEVICES (I.E. SILT FENCE) SHALL BE REMOVED ONCE
CONSTRUCTION IS COMPLETE AND THE EXPOSED AND REGRADED SECTIONS ARE STABILIZED.
3. ALL SEEDED AREAS SHALL BE FERTILIZED, RESEEDED AS NECESSARY AND MULCHED,
ACCORDING TO THE SEEDING PLAN (SHEET DOD -02) TO MAINTAIN A VIGOROUS, DENSE

DEFINITION
Controlling runoff and erosion on disturbed areas by establishing vegetative cover with seed.
To reduce erosion and decrease sediment yield from disturbed areas, and o permanently stabilize
such CROs in a manner that is economical, adapts to site conditions, and allows selection of the
most appropriate plant materials.
SPECIFICATIONS
SFFDRFD REQUIREMENTS
Establishment of vegetation should not be attempted on sites that are unsuitable due to excessive
soil compaction, inappropriate soil texture, poor drainage, concentrated overland flaw, or steepness of
slope until measures have been taken to correct these problems.
To maintain a good stand of vegetation, the soil must meet certain minimum requirements as a
growth medium. The existing soil should have these criteria:
• Enough fine-grained (silt and cloy) materiol to maintain adequate moisture and nutrient supply
(available water capacity of at least .05 inches water to 1 inch of soil).
• Sufficient pore space to permit root penetration.
• Sufficient depth of soil to provide an adequate root zone. the depth to rock or impermeable
layers such as hardpons should be 12 inches or more, expect on slopes steeper than 2:1 where
the addition of sail is not feasible.
• A favorable pH range for plan growth, usually 6.0 - 6.5.
Free from large roots, branches, stones, large clods of earth, or trash of any kind. Clods and
stones may be left an slopes steeper than 3:1 if they are to be hydro seeded.
If any of the above criteria are not mel - i.e., if existing soil is loo coarse, dense, shallow or
acidic to foster vegetation - special amendments are required. the soil conditioners described below
may be beneficial or, preferably, top soil may be applied.
SEEDBED PREPARATION
Install necessary mechanical erosion and sedimentation control practices before seeding, and complete
grading according to the approved plan.
Lime and fertilizer needs should be determined by soil tests. Direction, sample cartons, and
information sheets are available through county Agricultural Extension offices. Testing is also done by
commercial laboratories.
When soil test results are not available, follow rotes suggested in the seeding specifications shown at
right. Application rates usually fall into the following ranges.
• Ground agricultural limestone:
Light -textured, sandy soils: 1 to 1-1/2 tons/acre
Heavy -textured, clayey soils: 2 - 3 tons/acre
• Fertilizer:
Grasses: 800-1200 Ib/acre of 10-10-10 (or the equivalent)
Grass -legume mixtures: 800-1200 Ib/ocre of 5-10-10 (or the equivalent)
Apply lime and fertilizer evenly and incorporate into the top 4-6 inches of soil by disking or other
suitable means. Operate machinery on the contour. When using a hydro seeder, apply lime and
fertilizer to a rough, loose surface.
Roughen surfaces prior to seeding.
Complete seedbed preparation by breaking up large clods and raking into a smooth, uniform surface
(slopes less than 3:1). Fill in or level depressions that can collect water. Broadcast seed into a
freshly loosened seedbed that has not been sealed by rainfall.
SEEDING
Seeding dates given in the seeding mixture specification are designated as 'best' or 'possible
Seedlings properly carried out within the 'best" dates have a high probability of success. It is also
possible to have satisfactory establishment when seeding outside these dates. However, 0s you
deviate from them, the probability of failure increases rapidly. Seeding an the last date shown under
"possible" may reduce changes of success by 30-50X. Always take this into account in scheduling
land -disturbing activities.
Use certified seed for permanent seeding whenever possible.
Labeling of -non -certified seed is also required by law. Labels contain important information on seed
purity, germination, and presence of wood seeds. Seeds must meet State standards for content of
noxious weeds. Do not accept seed containing "prohibited' noxious weed seed.
Inoculate legume seed with mizobium bacteria appropriate to the species of legume. Apply seed
uniformly with a cyclone seeder, drop -type spreader, drill. cultipacker seeder, or hydro seeder on
firm, friable seedbed.
When using a drill or cultipacker seeder, plant small grains no more than 1 inch deep, grasses and
legumes no more than 1/2 inch. Equipment should be calibrated in the field for the desires seeding
rate.
When using broadcast -seeding methods, subdivide the area into workable sections and determine the
amount of seed needed for each section. Apply one-half the seed while moving back and forth
across the area, making o uniform pattern: then apply the second half in the some way, but moving
at right angles to the first pass.
Mulch oil plantings immediately after Seeding.
HYDRO SEEDING
surface roughening is particularly important when hydro seeding, as a roughened slope will provide
some natural coverage for lime, fertilizer, and seed. The surface should not be compacted or
smooth. Fine seedbed preparation is not necessary for hydro seeding operations: large clods, stones,
and irregularities provide cavities in which seeds can lodge.
Rate wood fiber (cellulose) application should be at least 2,000 Ib/acre.
Apply legume inoculonts at four times the recommended rate when adding inoculant to a hydro
seeder slurry.
If a machinery breakdown of 1/2 to 2 hours occur, add 50% more seed to the tank, based on the
proportion of the slurry remaining. This should compensate for damage seed. Beyond 2 hours, a full
rate of new seed may be necessary.
Lime is not normally applied with a hydraulic seeder because it is abrasive. It can be blown onto
sleep slopes in dry form.
MAINTENANCE
Generally, a stand of vegetation cannot be determined to by fully established until sail cover has
been maintained for one full year from planting. Inspect seeded areas for failure and make necessary
repairs and reseedings within the some Season, if possible.
Reseeding --If a stand has inadequate cover, re-evaluate choice of plant materials and quantities of
lime and fertilizer. Re-establish the stand after seedbed preparation or over -seed the stand.
Consider seeding temporary, annual species if the time of year is not appropriate for permanent
seeding.
If vegetation fails to grow, soil must be tested to determine if acidity or nutrient imbalance is
responsible.
Fertilization --On the typical disturbed site, full establishment usually requires re -fertilization in the
second growing season. Fine turf requires annual maintenance fertilization. Use soil tests if possible
or follow the guidelines given for the specific seeding mixture.
