9. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application:___ T_ he project is located in a residential portion of the cit~just
downstream from a small pond. Land to the north is occupied b~golf course, and land to
the south is occupied by the floodplain of Hewlett's Creek. There is an existing gravity
Updated 11/1/2005
Page 2 of 9

sewer and force main located with the floodplain, and a portion of the proposed easement
will cross the existing maintained easement.
10. Describe the overall project in detail, including the type of equipment to be used: The
overall project includes the replacement of approximately 6,640 feet of a failing 24-inch
sewer force main that was constructed more than 20 years ago. The new section of force
main will be approximately 6,600 feet in length and will be rerouted along surface roads to
the north of the existing force main, which will be abandoned in place. Other than the
proposed crossing, one other crossing will be installed using directional drillin teg chniques to
avoid impacts. The proposed crossing will be installed by open cut techniques using
excavators. Directional drilling is not an option for this crossing due to the len tg_h and
associated costs of the crossing, and because the existing utility lines and houses in the area
don't provide the necessary work space.
11. Explain the purpose of the proposed work: The work is necessaryplace a failing force
main. There have been two major ruptures of the existing force main during the last 2 years.
The new main will be rerouted along surface streets to avoid extensive impacts that would be
necessary to replace the line in place, and to provide ease of access to the main.
IV. Prior Project History
If jurisdictional determinations and/or permits have been requested and/or obtained for this
project (including all prior phases of the same subdivision) in the past, please explain. Include
the USAGE Action ID Number, DWQ Project Number, application date, and date permits and
certifications were issued or withdrawn. Provide photocopies of previously issued permits,
certifications or other useful information. Describe previously approved wetland, stream and
buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project,
list and describe permits issued for prior segments of the same T.LP. project, along with
construction schedules. The existing line has been in service since 1983. It is not know if
previous permits were issued when the force main was first installed, but it is assumed that the
work was authorized without written notification, pursuant with Federal and State regulations
that were in effect at the time.
V. Future Project Plans
Are any future permit requests anticipated for this project? If so, describe the anticipated work,
and provide justification for the exclusion of this work from the current application.
There_are no plans to conduct additional utility line improvements in the Hewlett's Creek area at
VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
Updated 11/1/2005
Page 3 of 9

permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs maybe included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: The proposed impacts will
result from the construction of a 24" force main using open cut installation techniques. The
crossing will require the disturbance of 0.096 acre of wetland, including the permanent
conversion of 0.074 acre of forested wetland to herbaceous wetland, and the temporary
disturbance of 8 linear feet of stream channel. The disturbed wetlands and stream will be
restored to existing_,Qrade upon completion of the work. Wetland areas will be reseeded with
wetland seed mix, which is included in the project specifications.
2. Individually list wetland impacts. Types of impacts include, but are not limited to
mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams,
separately list impacts due to both structure and flooding.

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
techniques to be followed during construction to reduce impacts. There is one other crossing
within the corridor that is proposed to be directionally drilled in order to reduce impacts. Due to
the existing residences in the vicinity of the crossing and the steepness of the slopes adjacent to
Updated 11 /1 /2005
Page 5 of 9

the stream, the use of directional drilling techniques is not practicable. There would also be the
risk of damming the two existing_gravity sewer lines located on the east side of the stream
channel: which could lead to a sewage spill. Because of these limitations, use of directional
drilling would have to be deeper and longer than is economically feasible. The anticipated cost
would be approximately $150,000. The width of the corridor at the location of the crossing has
also been reduced to 40 feet to be in compliance with Wilmington District Regional Conditions.
Lastly, the purpose of the project is to relocate the force main out of the wetlands that run
parallel to Hewlett's Creek, to help reduce the potential for environmentall~gin~ sewer
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.
USAGE - 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 USAGE 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 (see DWQ website for most current
version.).
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.
Due to the minimal impact to streams and wetlands (i.e., less than 1/lOt" acre total), and
because of efforts made to avoid and minimize impacts to wetlands, no mitigation is
proposed.
Updated 11/1/2005
Page 6 of 9

2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at http://www.nceep.net/pas/inlieureplace.htm. If use of the NCEEP is proposed,
please check the appropriate box on page five and provide the following information:

XI. Stormwater (required by DWQ)
Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss
Stormwater controls proposed in order to protect surface waters and wetlands downstream from
the property. If percent impervious surface exceeds 20%, please provide calculations
demonstrating total proposed impervious level. The project will not result in the addition of any
paved or impervious surfaces.
XII. Sewage Disposal (required by DWQ)
Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of
wastewater generated from the proposed project, or available capacity of the subject facility.
As the project is a replacement of existing infrastructure, no additional wastewater will be
generated. The project purpose is to update the existing facilities to prevent future sewage spills.
XIII. Violations (required by DWQ)
Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules?
Yes ^ No
Is this an after-the-fact permit application? Yes ^ No
XIV. Cumulative Impacts (required by DWQ)
Will this project (based on past and reasonably anticipated future impacts) result in additional
development, which could impact nearby downstream water quality? Yes ^ No
If yes, please submit a qualitative or quantitative cumulative impact analysis in accordance with
the most recent North Carolina Division of Water Quality policy posted on our website at
http://h2o.enr.state.nc.us/ncwetlands. If no, please provide a short narrative description:
Updated 11/1/2005
Page 8 of 9

The project will not increase the area served by the existing utilities to be upgraded. The force
main to be abandoned is the same diameter and has the same capacity of the proposed
replacement. Accordingly, no cumulative impacts are anticipated to result from the project.
XV. Other 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).
Due to the condition of the existing infrastructure, the applicant requests an expedient review of
the proposal so that the work can proceed as soon as possible. This is imperative to reduce the
possibility of future spills in the Hewlett's Creek area resulting from a rupture in the failin fg orce
main to be replaced.
