APPROVAL of 401 Water Quality Certification with Additional Condition
Dear Mr. Deal:
You have our approval, in accordance with the attached conditions, to trench, excavate and backfill a total of 200 linear feet of
streams in order to construct four stream crossings associated with the North Charlotte Outer Loop Sewer Line from North of NC 27 to
Northeast of SR 2042, as you described in your application received by the Division of Water Quality on May 9, 2002. After reviewing
your application, we have decided that this fill is covered by General Water Quality Certification Number 3374, which can be viewed on
our web site at http://h2o.enr.state.nc.us/ncwetlands . This Certification allows you to use Nationwide Permit Number 12 when the Corps
of Engineers issues it. In addition, you should get any other federal, state or local permits before you go ahead with your project including
(but not limited to) Sediment and Erosion Control, Coastal Stormwater, Non-Discharge and Water Supply Watershed regulations. Also
this approval will expire when the accompanying 404 permit expires unless otherwise specified in the General Certification.
This approval is only valid for the purpose and design that you described in your application. If you change your project, you must
notify us in writing and you may be required to send us a new application for a new certification. If the property is sold, the new owner
must be given a copy of the Certification and approval letter and is thereby responsible for complying with all conditions. If total wetland
fills for this project (now or in the future) exceed one acre, compensatory mitigation may be required as described in 15A NCAC 2H .0506
(h). For this approval to be valid, you must follow the conditions listed in the attached certification and the additional condition listed
below:
1. A cross vane shall be installed immediately downstream of the sewerline at each crossing location. Please reference the
Internal Technical Guide for Stream Work in North Carolina, Version 3.0, April 2001 (copy attached) for guidance in the location
and design of these cross vanes.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You must act within 60 days
of the date that you receive this letter. To ask for a hearing, send a written petition which conforms to Chapter 150B of the North Carolina
General Statutes to the Office of Administrative Hearings, P.O. Box 27447, Raleigh, N.C. 27611-7447. This certification and its conditions
are final and binding unless you ask for a hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act. If you have any

Charlotte-Mecklenburg Utilities (CMU) proposes 8-inch, 24-inch, and 42-inch ductile
iron sewer lines to be installed along Long Creek and along the proposed I-485 corridor,
which is part of the North Carolina Department of Transportation's proposed I-485 outer
loop project. The proposed 8-inch sewer line is approximately 423 feet in length, while
the 24-inch sewer line is approximately 1,654 feet in length, and the proposed 42-inch
sewer line is approximately 1,678 feet in length. The proposed 24-inch and 42-inch
sewer lines are parallel to each other and travel across the proposed I-485 corridor. In
order to tie the proposed lines into the existing sewer system, the 8-inch sewer line has to
cross Long Creek once. The 24-inch and 42-inch sewer lines also have to cross Gum
Branch once and Long Creek twice in order to make the appropriate tie in.
Charlotte-Mecklenburg Utilities hereby authorizes Mr. Kevin Hinde of Barbara H.

State Project No. 8.U672212, TIP No. R-2248C
Dear Sir:
Charlotte-Mecklenburg Utilities (CMU) proposes 8-inch, 24-inch, and 42-inch ductile
iron sewer lines to be installed along Long Creek and along the proposed I-485 corridor,
which is part of the North Carolina Department of Transportation's proposed I-485 outer

is approximately 1,678 feet in length. The proposed 24-inch and 42-inch sewer lines are
parallel to each other and travel across the proposed 1-485 corridor. In order to tie the
proposed lines into the existing sewer system, the 8-inch sewer line has to cross Long
Creek once. The 24-inch and 42-inch sewer lines also have to cross Gum Branch once
and Long Creek twice in order to make the appropriate tie in. In the same project area,
there are 12-inch and 18-inch sewer lines also having to tie into active sewer systems.
The proposed 12-inch and 18-inch sewer lines are not conflicting with any creeks, but do
involve tie-ins with the proposed 24-inch and 42-inch lines. There are five areas where
tie-ins have to be made to the active sewer systems. The proposed 8-inch and the 42-inch
sewer lines are being installed for future expansion in the area and the purpose of
preventing any future detriments to Long Creek and Gum Branch.
The North Carolina Department of Transportation (NCDOT) is currently seeking the
404/401 permits on the above referenced project. The 8-inch, 24-inch, and 42-inch sewer
lines proposed by Charlotte-Mecklenburg Utilities have portions which are located within
the construction limits of the NCDOT project for which they are currently pursuing
permits and portions just outside of the NCDOT construction limits. The areas of
concern with the 8-inch, 24-inch, and 42-inch sewer lines are located just outside of the
NCDOT construction limits. The Charlotte-Mecklenburg Utilities does not want, in any
way, to delay the NCDOT permitting process.

IMPACTS TO THE WATERS OF THE UNITED STATES
The proposed 8-inch, 24-inch, and 42-inch sewer lines are ductile iron pipe that will tie
into an existing sewer system along Long Creek. In order to tie the proposed lines into
the existing sewer system, the 8-inch sewer line has to cross Long Creek once. The 24-
inch and 42-inch sewer lines cross Gum Branch once and Long Creek twice in order to
make the appropriate tie in. Due to the shallow depth of the existing sewer system along
Long Creek, the proposed 8-inch line has the top of pipe exposed at one Long Creek
crossing and the proposed 24-inch pipe has top of the pipe exposed at two Long Creek
crossings.
The sewer lines had to be designed to tie into the existing system, which meant that the
elevations at the end of the proposed lines had to be held at the elevation of the existing
tie-in lines. The proposed 8-inch and 24-inch sewer lines were placed as deep as possible
through the creek crossing areas in order to minimize the amount of exposed pipe in the
creek. The tie-in points were actually moved to different points on the existing sewer
system in order to try and get more fall through the proposed sewer lines; therefore,
attempting to get completely under the creek. The existing sewer system was laid
shallow and on an average slope of approximately 0.13% which did not allow hardly any
difference in elevations. This proved that a change in the tie-in locations would give us
practically no help in getting more of an elevation change through the proposed system.
With the horizontal alignment of the sewer lines being dictated by NCDOT construction
and the right-of-way being purchased, the alignment of the proposed sewer lines were
fixed. Being that the horizontal alignment was fixed, the idea of using an inverted siphon
was considered to try and cross under the creek. The inverted siphon option requires
sufficient head through the sewer lines which could not be obtained due to the lack of fall
in the proposed sewer lines from tie-in to tie-in. With this being the case, the inverted
siphon option was not feasible and impractical. Another idea was to just encase the pipe
in concrete where it was exposed in the creek, but that would just add to the exposure
problem. In order to ensure protection to the exposed ductile iron pipe and no leakage,
restrained joint pipe and watertight joints are specified in the design. The pile piers are
also specified in the design to prevent any flotation that could potentially occur.
A benefit to the location of the proposed 24-inch and 42-inch sewer lines is that it
eliminates one area where the existing 21-inch sewer line is exposed in Gum Branch. At
this location, the existing 21-inch sewer pipe is sitting on the bed of Gum Branch (See
attached photos). At the Gum Branch creek crossing, the proposed 24-inch and 42-inch
sewer lines are at a sufficient depth to get under the creek and eliminate the need for the
exposed 21-inch sewer pipe.
Total proposed stream impacts from the installation of the sewer lines will be 0.29 acre.
The total length of the proposed stream impacts will be approximately 200 linear feet

1
• y

which is considerably less than the 500 feet required for the Nationwide Permit 12. The
impacts are approximately 158 linear feet for Long Creek and 42 linear feet for Gum
Branch. These lengths are also measured from top of bank to top of bank; therefore,
using the maximum length.
The soil from the excavation will be placed on uplands until it is time for it to be used for
backfill. At each creek crossing, a causeway will be constructed across one half of the
creek in order to install the first half of the sewer line. After the first half of the sewer
line is installed, the causeway will be moved to the other half of the creek in order to
finish installing the second half of the sewer line. Any exposed slopes and stream banks
will be stabilized immediately upon completion of the water line being installed.
MITIGATION
For the stream crossings and areas outside of the NCDOT right-of-way, erosion control
measures are shown on the plans and will be provided to minimize sedimentation and
turbidity in Gum Branch and Long Creek during installation of the 8-inch, 24-inch, and
42-inch sewer lines. For the portion of the proposed sewer lines being installed within
the NCDOT construction limits, the mitigation will be provided by NCDOT. After the
sewer lines are installed, the areas will be restored back to the preconstruction contours
and revegetated with the native species of the area. The stream banks will be protected
by using stream bank stabilization which is specified on the plans, profiles, and details.

were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
Please refer to the Cover Letter for a detailed explanation.

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 March 9, 2000, 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 NCWRP 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
htti)://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.
For the stream crossings and areas outside of the NCDOT right-of-way, erosion control measures are
shown on the plans and will be provided to minimize sedimentation and turbidity in Gum Branch and
Long Creek during installation of the 8-inch 24-inch and 42-inch sewer lines. Erosion control
measures such as clean water diversion ditches temporary diversion ditches silt fence and temporary
rock sediment dams are incorporated into the design. For the portion of the proposed sewer lines
being installed within the NCDOT construction limits the mitigation will be provided by NCDOT.
After the sewer lines are installed the areas will be restored back to the preconstruction contours and
revegetated with the native species of the area The stream banks will be protected by using stream
bank stabilization which is specified on the plans profiles and details. (See the Cover Letter for
more information)
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that
you would like to pay into the NCWRP. Please note that payment into the NCWRP must be
reviewed and approved before it can be used to satisfy mitigation requirements. Applicants
Page 10 of 13
will be notified early in the review process by the 401/Wetlands Unit if payment into the
NCWRP is available as an option. For additional information regarding the application
process for the NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/index.htm. If
use of the NCWRP is proposed, please check the appropriate box on page three and provide
the following information:
IX.
Amount of stream mitigation requested (linear feet): N/A
Amount of buffer mitigation requested (square feet):
Amount of Riparian wetland mitigation requested (acres):
Amount of Non-riparian wetland mitigation requested (acres):
Amount of Coastal wetland mitigation requested (acres):
Environmental Documentation (DWQ Only)
Does the project involve an expenditure of public (federal/state) funds or the use of public
(federal/state) land?
Yes ® No ?
If yes, does the project require preparation of an environmental document pursuant to the
requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)?
Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA
coordinator at [phone] to review current thresholds for environmental documentation.
Yes ? No
If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a
copy of the NEPA or SEPA final approval letter.
Yes ? No
X. Proposed Impacts on Riparian and Watershed Buffers (DWQ Only)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.
Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Neuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and
Water Supply Buffer Requirements), or other (please identify )?
Yes ? No ® If you answered "yes", provide the following information:
Identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer
mitigation is required calculate the required amount of mitigation by applying the buffer
multipliers.

If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation
of Property, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or
Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as
identified within 15A NCAC 2B .0242 or.0260.
XI. Stormwater (DWQ Only)
Describe impervious acreage (both 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.
For the construction of the nronosed sewer lines no impervious area will be added; therefore,
there will be no effects on the stormwater runoff.
XII. Sewage Disposal (DWQ Only)
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.
Due to the construction being a relocation of existing sewer lines, no wastewater will be
generated from the proposed project.
XIII. Violations (DWQ Only)
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
Page 12 of 13
XIV. 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).
