9. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: An existing 30-inch concrete pipeline is present within the
project corridor. Upland area on the west side of the project corridor is undeveloped with
exception to the structures associated with the existing water line. An existing railroad line is
present in the project corridor on the east side of the Cape Fear River. The remainder of the
project corridor is comprised of wetlands and surface waters.
The surrounding area is comprised mainly of undeveloped woodland wetland and surface
waters. A public boat ramp facility is located on the west bank of the river to the north of the
project. A former boat building facility is located on the west bank of the river south of the
project. Other industrial facilities are present to the north and south along the west bank of
the Cape Fear River.
10. Describe the overall project in detail, including the type of equipment to be used:
Approximately 2,400 linear feet (If)of raw water line will be installed using directional bore
technology utilizing a cofferdam, marsh mats, a barge drill rigs monitoring offices and
equipment and a batch/separator plant.
WEST SIDE OF PROJECT - The drill rig construction offices monitoring center, and
drilling spoil pile will be located in uplands on the western bank of the Cape Fear River. The
sections of new water line will be fused together and tested on the west side of the project in
uplands. The drill rig will begin bore operations on this side of the project in uplands
Approximately 1,000 cubic yards of earthen spoil will be generated from the operation This
material will be stockpiled and distributed in the project corridor in uplands once drilling
operations are complete.
EAST SIDE OF THE PROJECT - A barge will be used to deliver marsh mats and
cofferdam materials from the Cape Fear River to the eastern end of the project The mats
will be placed in the marsh extending east from the east side of the Cape Fear River to the
proposed HDD cofferdam area. The access mat path will measure approximately 400 feet
long by 20 feet wide. The cofferdam will be a maximum of 1,000 square feet (0.02 acrehin
area and will be bound by the existing pipeline to the north and marsh mats around the other
sides. There will be a total of approximately 9,800 feet (0.22 acre) of temporary marsh mats
A total of approximately 10,800 square feet (0.24 acre) of temporary impact is proposed for
both the marsh mats and cofferdam. A small drill rig will be lifted into the cofferdam by
crane or helicopter. This rig will fit entirely into the cofferdam and will only be used to pull
the drilling head and water line through the bore hole No drilling mud or spoils will be
processed from this cofferdam. A restraining collar will be placed around the new line to
secure it for when the line is reactivated. The new line will be connected to the existing
aboveground water line as supported from wooden piers similar to the supports of the
existing pipeline.
Mobilization is scheduled for early January 2008 with drilling to last for four weeks
beginning in mid-February and finishing by mid-March Demobilization will end in early
May.
Page 7 of 14
Black & Veatch will schedule a pre-construction meeting with regulatory personnel and they
will have an engineer onsite to monitor drilling activities.
A project narrative prepared by Black & Veatch has been included.
11. Explain the purpose of the proposed work: The purpose of this project is to replace the
portion of the existing raw water line that crosses under the Cape Fear River. That section of
line is currently exposed on the bottom of the Cape Fear River, damaged and vulnerable to
further damage. This replacement will allow the Authority to provide drinking water to
residents of New Hanover County and the City of Wilmington safely and reliably during
summer peak flow periods.

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
Page 10 of 14
techniques to be followed during construction to reduce impacts. Directional bore technology is
being utilized to avoid impacts to the Cape Fear River and a majority of the freshwater and
coastal wetlands within the project corridor. This project originally began as an approximately
4,000 linear foot boring operation with drilling operations to occur within an approximately
8,000 square foot cofferdam on the east end of the project in coastal wetlands near Toomer's
Creek The drilling operation was switched to the west end of the project reducing the cofferdam
size to 1,000 square feet, allowing drilling mud accumulation to occur in uplands instead of over
coastal wetlands and eliminating potential impacts to Toomer's Creek.
A pre-construction meeting will be scheduled by Black & Veatch. Black & Veatch will also
have an engineer on-site during construction to monitor drilling activities.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.us/ncwetlands/strmgide.html.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
The 1,000 square foot area temporary impacted by the cofferdam construction will be
returned to pre-existing grade and stabilized using native wetland vegetation. The area
Page 11 of 14
beneath the marsh mats will be inspected once they are removed following demobilization.
Disturbed areas will be returned to pre-existing grade and stabilized using native wetland
vegetation.

Uther Circumstances (Optional):
It is the applicant's responsibility to submit the application sufficiently in advance of desired
construction dates to allow processing time for these permits. However, an applicant may
choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).
Installation of the line is expected to take approximately four (4) months Peak water flows
begin in June. In order to have this line in service in time mobilization will need to begin in
early January with drilling from mid-February to mid-March This also takes into consideration
the primary nursery area moratorium for filling and excavating beginning April 1 Construction
of final ties to the existing water line will extend into April with completion by May 1
