Reference: Pre - Construction Notification (PCN) and Application for Nationwide #13 Permit for
a Duke Energy Project on Silas Creek Parkway in Winston Salem, NC.
Mr. Thomas and Ms. Homewood:
Geoscience & Technology, P.A. (GeoSci), on behalf of Duke Energy and Cole Land & Timber,
LLC, is pleased to submit this application for a Nationwide #13 Permit for activities related to
mitigation of erosion near a Duke Energy power line transmission tower adjacent to Salem Creek
in Winston Salem, NC.
This document contains explanatory text in support of various sections of the PCN. Text below is
numbered according to the corresponding section of the PCN form.
CPrtinn R Id
Duke Energy, Forsyth County, NC
404/40 1. PC N
April 201

Note: Please refer to attached Drawing Sheets S- I and -2 for project location and details
Stormwater discharge from the properties noted in 3B.la of the PCN has eroded a deep cut in the
former municipal landfill adjacent to a metal Duke Energy power line transmission tower The
erosion feature has exposed and is threatening the integrity of the tower base. The erosion has
created a cut through the bank of Salem Creek that is approximately four feet wide
Q ?Otll n R 2a
Note: Please refer to attached Drawing Sheets S -I and -2 for project location and details.
The proposed project includes- t) redirecting the stormwater flow via a new 24 -inch RCP
beginning at the discharge of an existing 15 -inch RCP away from the base of the tower (Sheet S-
I and S -2, Detail 3); 2) to mitigate further erosion of the stream bank, the discharge from the new
RCP will be directed onto a 12' X 6' X 12" (Yabion mattress and then onto a 1'- 3" thick Class l
Riprap apron placed on Terra -Tex No. 4 Filter Fabric (Sheet S -2, Detail 1), and, 3) the erosion
feature will be filled by placing a wall of gabions behind the existing remnant of the stream bank
and backfilling the gully with clean fill (Sheet S -2, Detail 2). No discharge of fill or dredging in
the stream is proposed by this project. The stream bank contours in the project area will be
restored to match the adjacent contours.
Equipment used in this project will include trackhoes, frontend loaders, dump trucks,
compactors, and various hand tools The project is expected to take two to three weeks to
complete depending upon weather conditions.
There are no proposed impacts to the stream. All excavation and backfilling is within the stream
bank and upgradient areas. After backfilling the existing erosion, the contours of the stream bank
in the erosion feature will be restored to adjacent existing contours. Please note that the existing
contours of the project area were determined at the time of closure of the municipal landfill at
this site and by the construction of the power transmission right of way.
Duke Energy. Forsyth County, NC April 201 5
40-4/401 , PC N

Section D la and I
As noted above and in the PCN form there are no proposed impacts to the stream and there are
no wetlands within the project area; therefore, impact justification and minimization are not
relevant All efforts will be made to prevent any sediment from reaching the stream throughout
the course of this project.
Section E?c.
Based on the expected disturbed area being less than I -acre a stormwater management plan will
not be required; LkIatthew Gantt with the Land Quality Division of NC Department of Natural
Resources confirmed this.
Sincerely,
GEOSCIENCE & TECHNOLOGY, P.A.
