APPROVAL of 401 Water Quality Certification with Additional Conditions
Dear Mr. Shearin:
Alan W. Klimek. P.E. Director
Division of Water Quality
September 6, 2005
DWQ# 05-1337
Mecklenburg County
You have our approval, in accordance with the attached conditions and those listed below, to
impact 150 linear feet (If) of perennial stream (110 If of Sugar Creek and 40 If of Hanes Branch) and
0.25 acre of wetland in order to construct sewer crossings in Mecklenburg County, as described in
your application received by the Division of Water Quality (DWQ) on July 18, 2005. After reviewing
your application, we have determined that this project is covered by Water Quality General
Certification Number 3374, which can be viewed on our web site at
http://h2o.enr. state.nc.us/ncwetlands. This General Certification allows you to use Nationwide Permit
Number 12 once it is issued to you by the U.S. Army Corps of Engineers. Please note that you
should get any otherfederal, state or local permits before proceeding with your project, including
those required by (but not limited to) Sediment and Erosion Control, Non-Discharge, and Water
Supply Watershed regulations.
The above noted Certification will expire when the associated 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.
In addition to the requirements of the certification, you must also comply with the following
conditions:
1. The Mooresville Regional Office shall be notified in writing once construction at the approved impact
areas has commenced.
2. No waste, spoils, solids, or fill of any kind shall be placed in wetlands, waters, or riparian areas
beyond the footprint of the impacts depicted in the Preconstruction Notification application. All
construction activities associated with this project shall meet, and/or exceed, those requirements

An Equal Opportunity/Affumative Action Employer- 50% Recycled/10% Post Consumer Paper

specified in the most recent version of the North Carolina Sediment and Erosion Control Manual and
shall be conducted so that no violations of state water quality standards, statutes, or rules occur.
3. The planting of native vegetation and other soft streambank stabilization techniques must be used
where practicable instead of riprap or other bank hardening methods. If riprap is necessary, it shall
not be placed in the stream bed, unless approved by the DWQ.
4. All wetlands, streams, surface waters, and riparian buffers located on the project site where impacts
are not allowed shall be clearly marked (example- orange fabric fencing) prior to any land disturbing
activities.
5. Sediment and erosion control devices shall not be placed in wetlands or waters to the maximum
extent practicable. If placement of sediment and erosion control devices in wetlands and waters is
unavoidable, they shall be removed and the natural grade restored within two months of the date the
Division of Land Resources has released the project.
6. Stormwater discharge structures at this site shall be constructed in a manner such that the potential
receiving streams (of the discharge) will not be impacted due to sediment accumulations, scouring
or erosion of the stream banks.
7. Upon completion of the project, the applicant shall complete and return the enclosed "Certificate of
Completion" form to the 401/Wetlands Unit of the NC Division of Water Quality.
8. Continuing Compliance. Charlotte-Mecklenburg Utilities shall conduct all activities in a manner so
as not to contravene any state water quality standard (including any requirements for compliance
with section 303(d) of the Clean Water Act) and any other appropriate requirements of state and
federal law. If DWQ determines that such standards or laws are not being met (including the failure
to sustain a designated or achieved use) or that state or federal law is being violated, or that further
conditions are necessary to assure compliance, DWQ may reevaluate and modify this certification to
include conditions appropriate to assure compliance with such standards and requirements in
accordance with 15 A NCAC 2H.0507(d). Before codifying the certification, DWQ shall notify
Charlotte-Mecklenburg Utilities and the US Army Corps of Engineers, provide public notice in
accordance with 15A NCAC 2H.0503, and provide opportunity for public hearing in accordance with
15A NCAC 2H.0504. Any new or revised conditions shall be provided to Charlotte-Mecklenburg
Utilities in writing, shall be provided to the United States Army Corps of Engineers for reference in
any permit issued pursuant to Section 404 of the Clean Water Act, and shall also become conditions
of the 404 Permit for the project.
It has come to our attention that there may be some confusion as to what is permissible when
crossing streams with utility lines. North Carolina's General Certification (GC) #3374, which
corresponds with Nationwide Permit #12 issued by the US Army Corp of Engineers, list 25 conditions
(requirements) for utility line construction. Based on observations that staff has made in the field, the
following conditions of GC 3374 are of particular importance:
#3) Mitigation may be required if the cumulative impacts of the project exceed 150 linear ft.
of stream. This is calculated for the entire project. (Example: four streams, each with 40
linear feet of impact. The total impact is considered to be 160 linear ft.)
#4) If the utility line runs parallel to a stream, the construction corridor shall not be closer
than 10 ft. to the channel (25 ft. if the stream is a HQW). This condition refers to the
construction corridor and not the utility line itself. At a minimum, a 10 ft. vegetated buffer

is required along the stream.
#9) If riprap is to be used it shall be kept to a minimum and imbedded into the streambed
below the normal high water level to allow passage of aquatic animals. During past site
inspections, it has been observed that riprap was "dumped" into the channel without regard
to stream flow. Where possible (especially in small channels), soft stream stabilization
techniques (matting and vegetative plantings) should be utilized. Also, the stream should
be restored and returned to its original grade and elevation.
#15) Permanent maintenance corridors are limited to 10 ft. in streams and wetlands.
Condition #4 above relates to the construction corridor, not the permanent maintenance
corridor. Permanent impacts (riprap, etc.) should not exceed 10 ft. of stream channel.
Frequently, staff have observed riprap lining of up to 40 ft of stream channel, which is far
in excess of what is needed for adequate stabilization.
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 that conforms to Chapter 150B of the North Carolina General Statutes to the Office of
Administrative Hearings, 6714 Mail Service Center, Raleigh, N.C. 27699-6714. 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 questions, please telephone Mr. Barry Love in the Mooresville Regional
Office at 704-663-1699 or Ms. Cyndi Karoly in the Central Office in Raleigh 919-733-9721.

VI. Proposed Impacts to Waters of the United States/Waters of the State
Page 7 of 13
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,
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 may be 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 include
installation of sewer pipe through part of a wetland, and the installation of sewer pipe across
Sugar Creek and a tributary of Sugar Creek, Hanes Branch. Four pipes will cross Sugar
Creek, but three of these pipes are in close proximity and may require only one trench,
minimizing the temporary impact to the Creek. The Hanes Branch of Sugar Creek will be
crossed once by sewer pipe. All stream crossings will be below the stream bed and existing
contours will be restored. Stream banks will be revegetated.
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.

impacts. Stream impacts include, but are not limited to placement of fill or culverts, dam
construction, flooding, relocation, stabilization activities (e.g., cement walls, rip-rap, crib
walls, gabions, etc.), excavation, ditching/straightening, etc. If stream relocation is proposed,
plans and profiles showing the linear footprint for both the original and relocated streams
must be included. To calculate acreage, multiply length X width, then divide by 43,560.

Describe all impacts to isolated waters, and include the type of water (wetland or stream) and
the size of the proposed impact (acres or linear feet). Please note that this section only
applies to waters that have specifically been determined to be isolated by the USACE.
8. Pond Creation
If construction of a pond is proposed, associated wetland and stream impacts should be
included above in the wetland and stream impact sections. Also, the proposed pond should
be described here and illustrated on any maps included with this application.
Pond to be created in (check all that apply): ? uplands ? stream ? wetlands
Describe the method of construction (e.g., dam/embankment, excavation, installation of
draw-down valve or spillway, etc.):
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.):
Current land use in the vicinity of the pond:
Size of watershed draining to pond: Expected pond surface area:
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.
The higher elevation and the adequate area of cleared land on the west side of Sugar Creek made
constructing the new flow equalization basin and grit facility at the chosen location the best
option. The sewer pipes shall cross the creek in order to connect the new facilities to the existing
treatment train on the opposite side of the creek. The sewer pipes are designed to cross streams
at near-perpendicular angles. After construction, disturbed stream banks will be restored to their
original contours. Rip rap will be placed below the high water mark, and stream banks above the
high water mark will be revegetated.
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
Page 10 of 13
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

X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ)
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.
1. Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Neuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 02B .0243 (Catawba) 15A NCAC
2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please
identify )? Yes ? No
2. If "yes", 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.
I I Zone* Impact Multiplier Required
(square feet) Mitieation
1 3 (2 for Catawba)
2 1.5
Total
* Zone 1 extends out 30 feet perpendicular from the top of the near bank of channel; Zone 2 extends an
additional 20 feet from the edge of Zone 1.
3. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e.,
Donation of Property, Riparian Buffer Restoration / Enhancement, or Payment into the
Riparian Buffer Restoration Fund). Please attach all appropriate information as identified
within 15A NCAC 2B .0242 or.0244, or.0260.
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
Page 12 of 13
demonstrating total proposed impervious level. The existing impervious acreage is
approximately 10% of the total acreage on the site. The new facilities will increase the
impervious area to approximately 150 of the total acreage on the site. The existing storm
drainage system will be modified and expanded to collect the additional runoff created by the
increased impervious area. The modifications include the addition of curbs and gutters, grass-
lined channels, catch basins, drop inlets, and storm water piping.
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.
Wastewater generated from the proposed project will be collected and discharged to the Sugar
Creek WWTP on site.
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/ncNvetiands. If no, please provide a short narrative description:
Additional capacity or growth will not be provided. This project will not expand the existin7
wastewater treatment service area. The project addresses wet-weather capacity inadequacies in
the system.
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).

Applicant/Agent's Signature Date

FINDING OF NO SIGNIFICANT IMPACT
Environmental Assessment For The Briar Creek Pump Station At The Sugar
Creek Wastewater Treatment Plant
Charlotte-iNlecklenburg Utilities
Pursuant to the requirements of the North Carolina Environmental Policy Act (N.C.G.S. § 113A-
1, et seq.), an environmental assessment (EA) has been prepared for the construction of a new
influent pump station at the Sugar Creek Wastewater Treatment Plant (WWTP) in Mecklenburg
County. The proposed pump station will have a capacity of 138,889 gallons per minute to
transfer influent wastewater flows from the Little Sugar and Briar Creek drainage basins to the
existing WWTP. The project also includes construction of a 130 million gallon per day (mgd)
grit removal facility, emergency generator, odor control system, and 20 million gallon flow
equalization basin. The primary need for the new facilities is the projected increase in wet-
weather flow conveyed to the WWTP through the planned installation of the Briar Creek Relief
Sewer.
Six project alternatives were analyzed for the EA including: consolidation of all facilities into a
new 200mgd pump station and a new 220mgd grit removal facility, use of the existing main lift
station and headworks facility with a new 160mgd pump station and 160mgd grit removal
facility, and taking no action. The preferred alternative was selected as it maximizes the use of
existing facilities, provides the greatest flexibility in utilizing the existing facilities as compared
to the other alternatives, and requires the second lowest estimated conceptual capital cost.
All the proposed facilities will be located at the existing WWTP site, on City of Charlotte owned
property. The treatment plant's service area is nearly built-out, some infill projects have
occurred recently, but the area is generally already developed. The total disturbed area for the
project will be approximately eight acres, including five that are already cleared. An aerial
photograph of the area depicting land parcels is included in the EA.
Construction of the project will require four stream crossings, perpendicular to the stream to the
extent possible in order to minimize impacts to sediments and riparian vegetation. Undisturbed
vegetated buffer zones will be left between streams and construction activities to the extent
possible. Following required federal and state permit conditions will help minimize potential
direct impacts. An Erosion and Sedimentation Control Plan will be submitted to DENR for
approval before construction commences.
Secondary and cumulative impacts associated with land development occurring within the
service area may result from the project. Various Charlotte and Mecklenburg County ordinances
and land development regulations will mitigate many of these impacts, including subdivision,
stormwater management, floodplain, and riparian buffer protection regulations. All measures are
described in greater detail within the EA.
The Division of Water Quality has concluded that the proposed project will not result in
significant impacts to the environment. This decision is based upon information provided in the
EA and review by governmental agencies. This EA and Finding of No Significant Impact are
prerequisites for the issuance of a Non-Discharge Permit and 401 Water Quality Certification by
the Division of Water Quality. An Environmental Impact Statement will not be prepared for this
project. This FONSI completes the environmental review record, which is available for
inspection at the State Clearinghouse.

IMPROVEMENTS, MECKLENBURG COUNTY
August 27, 2002
Project Applicant: Charlotte-Mecklenburg Utilities
Project Number: SCH 02-E-4300-0374
DWQ # 13101
Responsible Agency: NC Department of Environment and Natural Resources
Division of Water Quality, Water Quality Section
Pursuant to the requirements of the North Carolina Environmental Policy Act (N.C.G.S. § 113A-1, er
seq.), an environmental assessment•(EA) has been prepared for sewer system improvements along Brier
Creek in Mecklenburg County. The project includes approximately 10.8 miles of 12- to 60-inch relief
and replacement sewer, a 68-MGD wastewater pump station, and some rehabilitation of the existing trunk
sewer along Brier Creek. The proposed improvements will increase capacity in the system to minimize
system surcharging and overflows and will accommodate build out of the service area. The project will be
phased over a 10-year period.
The existing Brier Creek sewer system has experienced increased wet-weather flows that have resulted in
system surcharging and overflows. Four alternatives and the no-action alternative were considered as part
of the EA process. The four alternatives included (1) off-line flow equalization storage facilities with
relief and replacement sewer, (2) wet weather pump station and force main with relief and replacement
sewer, (3) single replacement and/or relief sewer, and (4) priority area or comprehensive collection sewer
rehabilitation. A single replacement and relief sewer with a receiving pump station was chosen as the
preferred alternative based on cost-effectiveness, reliability, operation and maintenance, envirc;lmental
impacts, and overflow reduction. The preferred alternative would remove four existing aerial sewer
crossings and has been designed to provide capacity for wet-weather flows at build out.
In recent years, the Mecklenburg County Department of Environmental Protection has observed high
levels of fecal coliform bacteria in Brier Creek. This project will help improve water quality in the area by
minimizing sewer overflows, a source of fecal coliform.
The proposed improvements begin upstream of Quiet Cove Court and follow Brier Creek downstream to
the existing Sugar Creek Wastewater Treatment Plant in west Charlotte. An expansion of the plant is not
planned in conjunction with this project. The proposed 68-MGD pump station will be constructed at the
existing Sugar Creek Plant to receive wastewater from the 14,000-acre Brier Creek service area. No new
service area is being added as part of this project.
The Brier Creek service area is located in the Catawba River Basin and is under the local government
jurisdiction of the City of Charlotte. The project applicant, Charlotte-Mecklenburg Utilities, is a joint
city-county public water and wastewater utility. The proposed sewer is routed through primarily
residential areas with pockets of commercial and light industrial-development. The Brier Creek service
area is nearly built-out. Most of the remaining development will occur as infill development and
redevelopment.

Brier Creek
Page 2
The sewer system has been routed to avoid several wetland areas and the Isaac Newton Alexander Mill
Ruin, a site of historical importance. Sewer pipeline will be installed using typical cut and cover methods.
The pipeline will cross a wetland located off Tyvola Road and Brier Creek at 14 locations, temporarily
disturbing less than one acre. At stream crossings, the pipelines will be installed at angles as close to 90
degrees as possible. Minimal, temporary impacts to aquatic species and habitat will occur due to stream
diversion and trenching at stream crossings- Riprap will be placed below the high water stage. There are
no records of known rate, threatened, or endangered species in or within 1 mile of the project area.
Disturbed areas will be restored to original contours and banks will be revegetated with woody plantings.
The wetland site will be restored after sewer installation.
Approximately S to 7 acres of previously disturbed woodland will be cleared. Tree removal has been
minimized due to installation within or adjacent to existing roads and right-of-ways. Cleared areas will
be revegetated with wildlife-friendly herbaceous species. Construction will be required to follow a state-
approved Erosion and Sediment Control Plan. Buffer zones will only be disturbed at the stream
crossings. Temporary construction-related noise and air quality impacts would be minimal.
Since the proposed improvements will accommodate build out of the service area, secondary and
cumulative impacts associated with new development may result from Elie project. However, the Brier
Creek service area is nearly built-out and most of the remaining development will occur as infill
development and redevelopment. The existing service area is expected to increase in population to build
out by 2030 (approximately 1417o). No new service area is being added as part of this project. Any
impacts related to new development induced by the project will be mitigated to a level of insignificance
through measures implemented in Charlotte. Naturally vegetated buffers, ranging in width from 35 feet
to 100 feet depending on the size of the drainage basin, are protected by city ordinance. Brier Creels
requires a 100-foot buffer. These buffers will help protect stream stabilization and restoration projects
along Brier Creek, and stream channels from future development impacts. In addition, other local
programs will mitigate impacts including water quality monitoring, stream restoration, floodplain
restrictions, stormwater ordinances, voluntary water conservation, and a reclaimed water program. These
measures are described in more detail in the EA.
The Division of Water Quality has concluded that the proposed project will not result in significant
impacts to the environment. This decision is based upon information provided in the EA and review by
governmental agencies. This EA and Finding of No Significant Impact (FONSI) are prerequisites for the
issuance of a Non-Discharge Permit and 401 Water Quality Certification by the Division of Water
Quality. An environmental impact statement will hot be prepared for this project. This FONSI completes
the environmental review record, \Vhich is available for inspection at the State Clearinghouse.

VI. Proposed Impacts to Waters of the United States/Waters of the State
Page 7 of 13
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,
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 may be 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 include
installation of sewer pipe through part of a wetland, and the installation of sewer pipe across
Sugar Creek and a tributary of Sugar Creek, Hanes Branch. Four pipes will cross Sugar
Creek, but three of these pipes are in close proximity and may require only one trench
minimizing the temporary impact to the Creek. The Hanes Branch of Sugar Creek will be
crossed once by sewer pipe. All stream crossings will be below the stream bed and existing
contours will be restored. Stream banks will be revegetated.
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.

local stormwater requirement, etc.):
Current land use in the vicinity of the pond:
Size of watershed draining to pond:
VII. Impact Justification (Avoidance and Minimization)
Expected pond surface area:
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.
The higher elevation and the adequate area of cleared land on the west side of Sugar Creek made
constructing the new flow equalization basin and grit facility at the chosen location the best
option. The sewer pipes shall cross the creek in order to connect the new facilities to the existing
treatment train on the opposite side of the creek. The sewer pipes are desivned to cross streams
at near-perpendicular angles. After construction, disturbed stream banks will be restored to their
original contours. Rip rap will be placed below the high water mark, and stream banks above the
high water mark will be revegetated.
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
Page 10 of 13
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/newetlands/strmgide.htm].
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.
- Disturbed stream banks shall be restored to their original contours, and all pipelines shall
be installed in compliance with the Nationwide No. 12 conditions. Stream banks above the
high water mark will be revegetated.
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

FINDING OF NO SIGNIFICANT IMPACT
Environmental Assessment For The Briar Creek Pump Station At The Sugar
Creek Wastewater Treatment Plant
Charlotte-Mecklenburg Utilities
Pursuant to the requirements of the North Carolina Environmental Policy Act (N.C.G.S. § 113A-
1, et seq.), an environmental assessment (EA) has been prepared for the construction of a new
influent pump station at the Sugar Creek Wastewater Treatment Plant (WWTP) in Mecklenburg
County. The proposed pump station will have a capacity of 138,889 gallons per minute to
transfer influent wastewater flows from the Little Sugar and Briar Creek drainage basins to the
existing WWTP. The project also includes construction of a 130 million gallon per day (mgd)
grit removal facility, emergency generator, odor control system, and 20 million gallon flow
equalization basin. The primary need for the new facilities is the projected increase in wet-
weather flow conveyed to the WWTP through the planned installation of the Briar Creek Relief
Sewer.
Six project alternatives were analyzed for the EA including: consolidation of all facilities into a
new 200mgd pump station and a new 220mgd grit removal facility, use of the existing main lift
station and headworks facility with a new 160mgd pump station and 160mgd grit removal
facility, and taking no action. The preferred alternative was selected as it maximizes the use of
existing facilities, provides the greatest flexibility in utilizing the existing facilities as compared
to the other alternatives, and requires the second lowest estimated conceptual capital cost.
All the proposed facilities will be located at the existing WWTP site, on City of Charlotte owned
property. The treatment plant's service area is nearly built-out, some infill projects have
occurred recently, but the area is generally already developed. The total disturbed area for the
project will be approximately eight acres, including five that are already cleared. An aerial
photograph of the area depicting land parcels is included in the EA.
Construction of the project will require four stream crossings, perpendicular to the stream to the
extent possible in order to minimize impacts to sediments and riparian vegetation. Undisturbed
vegetated buffer zones will be left between streams and construction activities to the extent
possible. Following required federal and state permit conditions will help minimize potential
direct impacts. An Erosion and Sedimentation Control Plan will be submitted to DENR for
approval before construction commences.
Secondary and cumulative impacts associated with land development occurring within the
service area may result from the project. Various Charlotte and Mecklenburg County ordinances
and land development regulations will mitigate many of these impacts, including subdivision,
stormwater management, floodplain, and riparian buffer protection regulations. All measures are
described in greater detail within the EA.
The Division of Water Quality has concluded that the proposed project will not result in
significant impacts to the environment. This decision is based upon information provided in the
EA and review by governmental agencies. This EA and Finding of No Significant Impact are
prerequisites for the issuance of a Non-Discharge Permit and 401 Water Quality Certification by
the Division of Water Quality. An Environmental Impact Statement will not be prepared for this
project. This FONSI completes the environmental review record, which is available for
inspection at the State Clearinghouse.

ENVIRONMENTAL ASSESSEMENT FOR THE 13RIER CREEK SEWER SYSTEM
IMPROVEMENTS, MECKLENBURG COUNTY
August 27, 2002
Project Applicant: Charlotte-Mecklenburg Utilities
Project Number: SCH 02-E-4300-0374
DWQ # 13101
Responsible Agency: NC Department of Environment and Natural Resources
Division of Water Quality, Water Quality Section
Pursuant to the requirements of the North Carolina Environmental Policy Act (N.C.G.S. § l 13A-1, er
seq.), an environmental assessment (EA) has been prepared for sewer system improvements along Brier
Creek in Mecklenburg County. The project includes approximately 10.8 miles of 12- to 60-inch relief
and replacement sewer, a 68-MGD wastewater pump station, and some rehabilitation of the existing trunk
sewer along Brier Creek. The proposed improvements will increase capacity in the system to minimize
system surcharging and overflows and will accommodate build out of the service area. The project will be
phased over a 10-year period.
The existing Brier Creek sewer system has experienced increased wet-weather flows that have resulted in
system surcharging and overflows. Four alternatives and the no-action alternative were considered as par;
Of the EA process. The four alternatives included (1) off-line flow equalization storage facilities with
relief and replacement sewer, (2) wet weather pump station and force main with relief and replacement
sewer, (3) single replacement and/or relief sewer, and (4) priority area or comprehensive collection sewer
rehabilitation. A single replacement and relief sewer with a receiving pump station was cbosert as the
preferred alternative based on cost-effectiveness, reliability, operation and maintenance, envircitmental
impacts, and overflow reduction. The preferred alternative would remove four existing aerial sewer
crossings and has been designed to provide capacity for wet-weather flows at build out.
In recent years, the Mecklenburg County Department of Environmental protection has observed high
levels of fecal coliform bacteria in Brier Creek. This project will help improve water quality in the area by
minimizing sewer overflows, a source of fecal coliform.
The proposed improvements begin upstream of Quiet Cove Court and follow Brier Creek downstream to
the existing Sugar Creek Wastewater Treatment Plant in west Charlotte, An expansion of the plant is not
planned in conjunction with this project. The proposed 63-MGD pump station will be constructed at the:
existing Sugar Creek Plant to receive wastewater from the 14,000-acre Brier Creek service area. No new
service area is being added as part of this project.
The Brier Creek service area is located in the Catawba River Basin and is under the local government
jurisdiction of the City of Charlotte. The project applicant, Charlotte-Mecklenburg Utilities, is a joint
city-county public water and wastewater utility. The proposed sewer is routed through primarily
residential areas with pockets of commercial and light industrial-d'evelopment. The Brier Creek service
area is nearly built-out. Most of the remaining development will occur as infill development and
redevelopment.

Bri er Creek
Page 2
The sewer system has been routed to avoid several wetland areas and the Isaac Ncwton Alexander Mill
Ruin, a site of historical importance. Sewer pipeline will be installed using typical cut and cover methods.
The pipeline will cross a wetland located off Tyvola Road and Brier Creel: at 14 locations, temporarily
disturbing less than one acre. At stream crossings, the pipelines will be installed at angles as close to 90
degrees as possible. Minimal, temporary impacts to aquatic species and habitat will occur due to stream
diversion and trenching at stream crossings. Riprap will be placed below the high water stage. There are
no records of known rare, threatened, or endangered species in or within 1 mile of the project area.
Disturbed areas will be restored to original contours and banks will be revegetated with woody plantings.
The wetland site will be restored after sewer installation.
Approximately 5 to 7 acres of previously disturbed woodland will be cleared. Tree removal has been
minimized due to installation within or adjacent to existing roads and right-of-ways. Cleared areas will
be revegetated with wildlife-friendly herbaceous species. Construction will be required to follow a state-
approved Erosion and Sediment Control Plan. Buffer zones will only be disturbed at the stream
crossings. Temporary construction-related noise and air quality impacts would be minimal,
Since the proposed improvements will accommodate build out of the service area, secondary and
cumulative impacts associated with new development may result from the project. However, the Brier
Creek service area is nearly built-out and most of the remaining development will occur as infill
development and redevelopment. The existing service area is expected to increase in population to build
out by 2030 (approximately 1470). No new service area is being added as part of this project. Any
impacts related to new development induced by the project will be mitigated to a level of insignificance
through measures implemented in Charlotte. Naturally vegetated buffcrs, ranging in width from 35 feet
to 100 feet depending on the size of the drainage basin, are protected by city ordinance. Brier Creek
requires a 100-foot buffer. These buffers will help protect stream stabilization and restoration projects
along Brier Creek, and stream channels from furore development impacts. In addition, other local
programs will mitigate impacts including water quality monitoring, stream restoration, floodplain
restrictions, stormwater ordinances, voluntary water conservation, and a reclaimed water program. These
measures are described in more detail in the EA.
The Division of Water Quality has concluded that the proposed project will not result in significant
impacts to the environment. This decision is based upon information provided in the EA and review by
governmental agencies. This EA and Finding of No Significant Impact (FONSI) are prerequisites for the
issuance of a Non-Discharge Permit and 401 Water Quality Certification by the Division of Water
Quality. An environmental impact statement will trot be prepared for this project. This FONSI completes
the environmental review record, which is available for inspection at the State Clearinghouse.
