Dear Mr. Pitts:
Subject: Certification of Compliance
with Stormwater Regulations
Bob Jamieson
Regional Manager
Project No. 920201
CP&L, Topsail 230 kV Substation
Pender County
The Wilmington Regional Office received the Stormwater
submittal for the subject project on February 6, 1992. Based on
our review of the project plans and specifications that indicate
a total built -upon area of 1.7 acres or 10.2 percent coverage for
the site, we have determined that the project complies with the
Stormwater Regulations set forth in Title 15A NCAC 2H. 1003
(a)(3). This Certification shall be effective from the date of
issuance until rescinded and the project shall be constructed in
accordance with the plans and specifications as filed with the
Wilmington Regional Office.
Any modification of the plans submitted to this Office or
further development of this site will require an additional
Stormwater submittal/modification and approval prior to
initiation of construction. Modifications include but are not
limited to; project name changes, transfer of ownership, redesign
of built -upon surfaces, addition of built -upon surfaces, redesign
or subdivision of project area.

EROSION CONTROL PLAN
TOPSAIL 230 kV SUBSTATION
We will construct the Topsail 230 kV Substation to serve the electrical load growth in the
Hampstead/Holly Ridge area. The in-service date is December 1, 1992.
The Topsail 230 kV Substation site is on NCSR 1592, off US Hwy 17, approximately two miles
north of Hampstead. The site is currently undeveloped and contains 16.7 acres; 6.8 acres of which
are wetlands. The enclosed topographic survey shows the wetlands along the southwest property line.
Relatively low but dense vegetation covers the wetland areas. Scattered immature pines cover the
upland areas. Existing ground surface elevations range from approximately 54 ft in the ditch near the
south corner to 61 ft along the northeast property line.
Westinghouse Environmental and Geotechnical Services, Inc. investigated the subsurface conditions at
the site with ten soil borings 10 feet deep and one, 30 feet deep. The borings generally encountered
loose to firm, sometimes clayey, fine to medium sand interbedded with a two -to -three -foot -thick layer
of very soft to soft clay. At the time of drilling, the groundwater was at an average depth of 3.5 feet.
The substation will have an initial fenced area of 170 feet by 210 feet and an ultimate fenced area of
260 feet by 210 feet. We will grade for the ultimate yard size 300 feet by 250 feet. The access road
will be 830 feet long and 20 feet wide. Most of the grading will consist of placing and compacting
off -site fill. I anticipate maximum cut and fill depths of 2.5 feet and 3.5 feet, respectively. We will
move between 4500 and 5000 cubic yards of soil, including strippings, to build the substation.
I anticipate the grading for the substation will proceed in the following sequence:
1.) At the access road entrance, the grading contractor will install pipe P2 in the existing ditch
along the west side of NCSR 1592. They will line the ditch with the Class A erosion control
stone at the inlet and outlet in general accordance with Sections 6.15 and 6.31 of the Erosion
and Sediment Control Planning and Design Manual (hereafter referred to as the Manual).
2.) At this location, the contractor will construct a temporary gravel construction entrance in
general accordance with Section 6.06 of the Manual and with Drawing Number RAC-24805.
3.) The contractor will clear approximately 4.5 acres for the access road, substation and
transmission. line tarp. The contractor will not clear outside the limits shown on Drawing
Number RDC-25819. They will either burn the trees and underbrush on site or dispose of
these off site.
4.) Concurrent with the clearing, the contractor will install the silt fencing along the southwest
and northwest sides of the cleared area. They will install the fencing in general accordance
with Section 6.62 of the Manual and Drawing Number RAC-24525.
5.) The contractor will excavate ditches D1 through D4 with 4 to 1, horizontal to vertical, side
slopes and will install stone check dams at the outlets of D3 and D4. They will temporarily
seed the ditches, using straw held in place with netting as the mulch. They will complete this
work in general accordance with Sections 6.10, 6.14, 6.21, 6.30 and 6.83 of the Manual.
(00460RMP.LVR)
EEB 5 1992
ij t lYl

6.) The contractor will install pipes P1A&B with flared end sections at the inlet and outlet and
with a Class A erosion control stone dissipator at the outlet. They will complete this work in
general accordance with Sections 6.15 and 6.41 of the Manual.
7.) The contractor will strip any topsoil or unsuitable material from the access road and substation
areas. Depending on the quality of the topsoil, they will either use it as fill or dispose of it
on site. They will complete this work in general accordance with Section 6.04 of the Manual.
8.) The contractor will grade the access road and substation, using 4 to 1, horizontal to vertical,
side slopes. This grading will consist mostly of replacing suitable strippings and placing off -
site fill soil. They will compact these soils in lifts, to 95 percent of the Standard Proctor
maximum dry densities. At the end of the rough grading and in general accordance with
Section 6.03 of the Manual, the contractor will roughen the cut and fill slopes to be seeded.
"Any borrow material brought onto this site must be from a legally operated mine or
other approved source. A single use borrow site or an area to waste material is only
permissible if it is operated under total control of the Financially Responsible person
or firm (CP&L) who is developing this site and a plan modification is submitted to
this (Land Quality Section) office that includes the area in question."
9.) The grading contractor will cover the access road with a 6-inch-thick layer of ABC stone.
The fence contractor will install the 7-foot-tall perimeter fence and 4-foot-tall access road
fence.
10.) The landscaping contractor will permanently seed, lime, fertilize and mulch all disturbed
areas outside the perimeter fence and access road. They will use straw held in place with
netting as mulch for the ditches. They will complete this work in general accordance with
Sections 6.03, 6.11 and 6.14 of the Manual.
11.) When the construction crews have completed the work inside the fence, the grading contractor
will fine grade this area and cover it with a 4-inch-thick layer of ABC stone.
12.) The contractor will reseed any areas needing repair. When all disturbed areas are stabilized,
the contractor will remove the sediment fence and check dams.
Enclosed as part of this Erosion Control Plan are: a table presenting the ditch and pipe design
conditions and parameters, our standard silt fence and construction entrance details, copies of the
referenced sections of the Manual, the grading plan and topographic survey.
We will complete the grading for this project in general accordance with the Memorandum of
Understanding between Carolina Power & Light Company and the Land Quality Section of the
Department of Natural and Economic Resources (now Environment, Health, and Natural Resources)
dated June 20, 1975.
