FINDING OF NO SIGNIFICANT IMPACT (FNSI)
Article I, Chapter 113A of the North Carolina General Statutes requires an action to be subject to
the requirements of the North Carolina Environmental Policy Act (NCEPA) if it involves the
expenditure of public funds and a potential impact is anticipated to the environment. The proposed
project has been evaluated for compliance with the North Carolina Environmental Policy Act and
determined to be a major agency action that will affect the environment.
Project Applicant: Water & Sewer Authority of Cabarrus County, North Carolina
Project Description: In this project, known as the Fuda Creek Interceptor, the Water and Sewer
Authority of Cabarrus County (WSACC) will construct gravity sewers to
serve western portions of the town of Harrisburg and an eastern section of
Mecklenburg County. The proposed interceptor is a 12- to 24-.inch diameter
interceptor sewer system approximately 22,400 feet in length. The proposed
infrastructure will parallel an existing interceptor and eliminate two (2) pump
stations. This project will allow for the Huntwicke Package wastewater
treatment plant to be eliminated. The Fuda Creek Interceptor will be
designed to convey all wastewater flow to the Back Creek Interceptor, then to
the Rocky River Regional Wastewater Treatment Plant.
Project Number: CS370382-20
Total Project Cost: $6,392,100
State Revolving Fund
Loan: $6,392,100
Mitigative measures will be implemented to avoid significant adverse environmental impacts, and
an environmental impact statement will not be required. The decision was based on information in
the 201 Facilities Plan and reviews by governmental agencies. An environmental assessment
supporting this action is attached. This FNSI completes the environmental review record, which is
available for inspection at the State Clearinghouse.
No administrative action will be taken on the proposed project for at least thirty calendar days after
notification that the FNSI has been published in the North Carolina Environmental Bulletin.
Sincerely,
t�� a'tm�

Division of Water Quality

ENVIRONMENTAL ASSESSMENT
A. Proposed Facilities and Actions
Figure 1 identifies the location of the proposed wastewater interceptor system.
New Interceptor System: The Water and Sewer Authority'of Cabarrus County (WSACC) serves the
regional wastewater needs of, and provides wastewater collection and treatment service for Cabarrus
County. The proposed project consists of installation of 4,055 linear feet (l.f.) of 12-inch diameter
gravity sewer, 4,90011. of 21-inch diameter gravity sewer, and 13,445 l.f. of 24-inch diameter
gravity sewer. The downstream portion of the interceptor will be installed parallel to 3,1001.f. of an
existing 12-inch diameter interceptor. A flow diversion structure will be incorporated to split the
incoming wastewater flow between the existing and proposed parallel interceptors. The proposed
infrastructure will eliminate the existing Claire Haven pump station and the Fuda Creek pump
station. This project will also allow for the existing Huntwicke package wastewater treatment plant
to be eliminated. The Fuda Creek Interceptor will be designed to convey wastewater flow to the
Back Creek Interceptor, and from there the wastewater is conveyed to the Rocky River Regional
Wastewater Treatment Plant.
B. Existing Environment
Topography and Soils: This proposed installation is located in the Fuda Creek drainage basin in
Cabarrus County and Mecklenburg County, which are in the Piedmont physiographic province of
North Carolina. Most of the interceptor route is along relatively flat terrain along the floodplain of
Fuda Creek. Elevations along the corridor range from approximately 556 feet above sea level at the
downstream end of the route near the confluence of Fuda Creek and Back Creek to around 675 feet
at the upstream end of the route in Mecklenburg County. Portions of the Fuda Creek Interceptor
route will encroach on the 100-year floodplain due to the necessity of gravity collection systems to
be placed at the lowest elevation practicable. The two dominant soil types present in the
construction corridor are Chewacla and Monacan soils. Chewacla soils are frequently flooded and
found in.floodplains along streams. Monacan soils are somewhat poorly drained soils typically
found in floodplains.
Surface Waters: The proposed project will involve crossing Fuda Creek nine times, and five
unnamed tributaries of Fuda Creek. The sewer will also cross Back Creek once to connect to the
Back Creek Interceptor. Fuda Creek is approximately 20 feet wide, and its tributaries are
approximately 10 feet wide. Fuda Creek and Back Creek are classified as Class C surface waters.
Water Supply: The drinking water supply sources for Cabarrus County are Lake Don T. Howell,
Lake Fisher, Lake Concord, and Lake Kannapolis, all of which are located in the Yadkin River
Basin.

C. Existing Wastewater Facilities
WSACC was established in 1992 to provide regional water and wastewater service to four member
utilities in Cabarrus County: the city of Concord, the city of Kannapolis, the town of Harrisburg,
and the town of Mt. Pleasant. WSACC's interceptor- system consists of over 67 miles of gravity
sewer sized 12 to 72 inches in diameter and four wastewater pump stations. WSACC operates two
wastewater treatment facilities, the 24-MGD Rocky River Regional WWTP and the 75,000 GPD
Muddy Creek WWTP. The majority of the interceptor system serves the Rocky River Regional
WWTP, which is a two -stage biological treatment facility that uses sodium hypochlorite for
disinfection. Facing the rapid population growth and development in the western portions of the
town of Harrisburg and eastern Mecklenburg County, the existing Fuda Creek Interceptor system -
3,1001.f. of 12-inch diameter gravity sewer and a small pump station in the downstream portion of
the project area - will run out of capacity in the near future. The proposed infrastructure will
parallel the route of the existing Fuda Creek Interceptor and will prevent future system failure due to
sanitary sewer overflows.
The effluent limits for the Rocky River Regional WWTP are:
Parameter Limit
Flow 24.0 MGD
CBOD (Summer) 17.0 mg/L daily average, 25.5 mg/L weekly average
CBOD (Winter) 25.0 mg/L daily average, 37.5 mg/L weekly average
NH3-N (Summer - Winter) 4 mg/L and l0mg/L
Total Suspended Residue 30 mg/L daily average, 45 mg/L weekly average
Fecal Coliform 200/100 ml daily average, 400/100 ml weekly average
D. Need for Proposed Facilities and Actions
The Fuda Creek Interceptor, which will collect wastewater throughout the Fuda Creek drainage
basin and convey it to the Rocky River Regional WWTP, is needed to protect the existing sewer
system from failure due to overflows. It will also provide municipal sewer service to some
developing areas in Cabarrus County. The University City area, located between the town of .
Harrisburg and Charlotte, is growing and pushing development into the area between these two
municipalities. The Harrisburg Area Plan is a planning document that was jointly developed
between Harrisburg and Charlotte to guide the long-term growth and development in the Harrisburg
area. In accordance with the Plan, WSACC has entered into an agreement with Charlotte -
Mecklenburg Utilities for the implementation of the Reedy Creek Interceptor, which will be located
to the south of Fuda Creek. This interceptor will inhibit the proliferation of package wastewater
treatment plants and pump stations in the area, and will extend the regional system provided by the
Rocky River Regional WWTP. WSACC has committed to allow wastewater connections only on
the north side of the proposed Reedy Creek Interceptor and the area on the south side of Reedy
Creek will currently be preserved as open space. Because Fuda Creek is located north of Reedy
Creek, the Fuda Creek area will be targeted for controlled residential development in accordance

with the Plan. This will encourage development to occur closer.to Harrisburg and discourage
sprawling growth in undeveloped areas of Cabarrus County.
E. Alternatives Analysis
WSACC needs to provide wastewater collection/transport facilities in the Fuda Creek basin to
prevent sewer overflows and to allow for future development. Accordingly, a 201 Facility Plan
Amendment was prepared and several alternatives were evaluated. A "no -action" alternative was
determined to be unacceptable because it would not allow WSACC to adequately collect and treat
wastewater from the Fuda Creek drainage basin, and the projected growth and development would
occur without adequate wastewater collection and treatment facilities in place. Without
implementation of the Fuda Creek Interceptor, the existing 12-inch interceptor would run out of
capacity in the very near future, and WSACC would have to deny service to future customers along
this reach of the interceptor, as well as the upstream customers anticipated from the land use
planning for Harrisburg. The "no action" alternative would likely be associated with more
widespread environmental impacts, including individual septic systems and private wastewater
treatment systems.
Because Cabarrus County contains areas with rock and clay, it is not feasible to implement
individual septic systems for the amount of flow to be carried by the proposed Fuda Creek
Interceptor. The alternative of implementing septic tank effluent pump (STEP) collection systems
for area is also not feasible due to the rocky nature of the area and poor soils.
The alternative of constructing an interceptor entirely along the south side of Fuda Creek was
evaluated. The south side of the creek contains wooded areas that would require clearing and the
loss of wildlife habitat. There is evidence of rock on the surface of the south side of Fuda Creek
with steeper terrain. Installing the interceptor along the south side of Fuda Creek would require
construction activities within 100 feet of existing homes. Also, a permanent right-of-way would
have to be created along the route to allow access for maintenance of the line. Constructing the
interceptor on the south side of the creek would require a total of 12 creek crossings. Because of its
potential disruption to residences along the route, the likely complexity of its installation, and
environmental impact, the option of constructing the interceptor on the south side of Fuda Creek
was rejected.
The alternative of constructing the Fuda Creek Interceptor primarily along the north side of the
creek was evaluated. When compared to the alternative of constructing the interceptor along the
south side of the creek, constructing the interceptor on the north side of the creek minimizes the
clearing of trees, the loss of wildlife habitat, minimizes wetland impacts, and allows two pump
stations and.a package wastewater treatment plant to be eliminated. Installing the interceptor along
the north side of the creek also maximizes maintenance access to the interceptor and minimizes
environmental consequences since the Fuda Creek Interceptor will use an existing 12-inch
interceptor right-of-way. Portions of the "south side".alternative are also included in this alternative
in order to preserve existing stream buffers. Because locating the interceptor primarily along the
north side of the creek minimizes the environmental impact of the proposed project, it is the

preferred alternative. The proposed project will consist of approximately 22,400 feet of 12-inch to
24-inch pipeline to be installed using open -cut construction primarily along the north side of Fuda
Creek.
F. Environmental Consequences, Mitigative Measures
Environmental Consequences
This project is known as the Fuda Creek Interceptor and is located in Cabarrus and Mecklenburg
Counties. The pipelines will be installed using open -cut construction. The total width of the
construction disturbance, including temporary sedimentation and erosion controls such as diversion
ditches, will be limited to 40 feet wide in wetland areas and 40 feet across streams.
Construction of the Fuda Creek Interceptor will not result in any direct, long-term changes in land
use because the pipeline will be installed entirely underground and the existing ground contours will
be restored. No local zoning or land use plans will need to be amended to accommodate changes
made possible by the proposed project. However, there may be some land use impacts that occur as
a result of temporarily displaced activities, but these impacts are expected to be minor and
short-term in nature. The proposed interceptor route crosses two existing roads, and the interceptor
is to be installed using jack -and -bore, tunneled, or open -cut construction. Open areas will be
reseeded and restored, but trees will not be replanted within the interceptor right-of-way. The only
permanent changes to the pipeline areas will be occasional mowing along the right-of-way corridors
to prevent trees and other large woody vegetation from becoming established. Mowing will
typically occur in February and March to protect small game nesting later in the year. There will be
no adverse impacts to soils in the project area, and no soil contamination is expected as a result of
this project.
Once construction of the sewer line is complete, no significant noise impacts are expected from the
operation of the sewer line. Noise levels may actually be reduced after construction of the
interceptor since the existing Fuda Creek pump station will be eliminated, reducing noise from the
operation of pumps and equipment.
Construction of the Fuda Creek Interceptor will be associated with short-term, localized air quality
impacts such as increases in suspended particulate matter due to dust stirred at the construction site
and exhaust emissions from diesel and gasoline powered equipment. No open burning will be
allowed. Slight odor is possible within a few feet of the manhole vents that will be a part of this
project, but the interceptor is designed with sufficient slope such that the wastewater will be
conveyed downstream without allowing the wastewater to stagnate and emit odors. The proposed
project will not result in any long-term effect on air quality.
Surface waters will be impacted during construction of the stream crossings since the streams will
be temporarily diverted to install the interceptor. Diversions of surface water to construct the
interceptor will not impact wetlands. Approximately 0.244-acre of stream channels will be
temporarily disturbed by the construction but will be restored after the construction. The proposed

project will not have any impact on groundwater quality or quantity. Construction and operation of
the proposed interceptor will not involve the use or discharge of any toxic substance: The Fuda
Creek Interceptor will be constructed within the 100-year floodplain because, in order to convey
wastewater flow by gravity, the interceptor must be constructed at the lowest elevation possible.
There is no practicable alternative. There will be no loss of flood storage capacity as a result of the
project because preconstruction topography will be restored after installation of the pipeline.
Construction of the proposed project may result in a short-term impact to the fishery resource and
habitat along the sewer line route. These impacts will result from a temporary increase in the
turbidity of the water, temporary loss of aquatic habitat in the construction area, loss of benthic
organisms in the stream crossing construction area due to a temporary diversion of streams, and a
temporary increase in the river velocity in the stream crossing construction area due to constricted
flows at the stream diversions. As soon as construction is complete, the turbidity levels are
expected to return to preconstruction levels. Fish species are expected to return immediately
although it may take longer for benthic organisms to recolonize the area. No long-term impacts to
fishery resources or habitats in Fuda Creek, its tributaries, or any other surface waters in the project
vicinity are expected as a result of the proposed project.
Approximately 15 acres of previously disturbed woodland, most of which is in the floodplain, will
be cleared as a result of construction of the interceptor, and the wildlife species and their habitats
associated with the interceptor corridor will be disturbed or displaced. Portions of the disturbed
forested areas will be converted to a herbaceous or scrub -shrub community as a result of the project.
Therefore, areas that are cleared for the interceptor- construction may support a different wildlife
community after the removal of trees and replacement with herbaceous vegetation. Because the
areas that will be disturbed provide relatively common habitat, this impact will not be significant.
The Fuda Creek Interceptor will not have any effect on prime or unique agricultural lands. The
proposed project will not have any significant impact on any public lands, or scenic, or recreational
areas. The Fuda Creek Interceptor will not disturb any known areas of archaeological or historical
value.
Mitigative Measures
To minimize the noise -related disturbance to the local community, construction activity will be
limited to normal daytime hours (7:00 A.M. to 7:00 P.M., Monday through Saturday) wherever
possible. In addition, large construction equipment will be equipped with proper noise attenuation
devices such as mufflers and silencers to minimize construction -related ambient noise level
increases.
To control the amount of dust created by construction, open construction areas will be sprayed
lightly with water. Discharges of vehicular airborne pollutants will be mitigated through the use of
proper emission control systems. Where located below the 100-year flood elevation, manholes will
be constructed with watertight frames and covers, which will minimize odors escaping from the
manholes.

Riparian vegetation will be preserved as much as possible. A minimum buffer of 40 feet will be
maintained in all riparian areas. A 100-foot buffer will be maintained in all riparian areas except
where they are not feasible due to steep topography, existing houses, or sewer rights -of -way that
must be avoided. Those trees that must be removed outside of the right-of-way will be cut near
ground level, leaving the stump and the roots in the bank for stability and to possibly sprout.
Excavated material will be stockpiled away from streams, and a DENR-approved Erosion and.
Sedimentation Control Plan will be followed during construction.
Stream crossings will be made perpendicular to the stream to the extent possible to minimize
impacts to stream sediments and riparian vegetation. The interceptor- will be installed completely
below grade at each stream crossing to prevent debris collection at the pipe crossing. Disturbed
stream banks at crossings will be restored to original contours and revegetated with natural
materials. Stabilization and seeding of banks at stream crossings will occur within 5 days
immediately after construction. A combination of rip rap (below the ordinary high water mark) and
woody plantings (above ordinary high water mark) will be used to stabilize the stream banks after
construction is complete. As recommended by the North Carolina Wildlife Resources Commission
(NCWRC), dormant cuttings of silky dogwood (Cornus anionuun) and silky willow (Salix sericea)
and/or rooted stock of elderberry (Sambuctes canadensis) will be used for restoration.
Undisturbed buffer zones will be left between streams and construction activities to the maximum
extent practicable, and buffer zones will only be disturbed for the nearly perpendicular stream
crossings. Once construction is complete, original contours will be restored in wetland areas and the
top 12 inches will be replaced with the stripped topsoil to provide a seedbank for re -vegetation. The
disturbed soil in wetlands will be reseeded with non -exotic vegetation. Anti -seep collars will be
provided at least every 150 feet along the pipeline in wetland areas to control the migration of
groundwater along the pipe bedding and to avoid draining wetland areas.
Any leaking construction equipment will be required to be fixed properly prior to continued use, and
pans will be placed under- the equipment to intercept any fluid if leaking. The construction
contractor will be required to dispose of this waste properly, in accordance with all state and local
rules.
Every reasonable effort will be made to minimize the extent of tree clearing required to construct
the proposed project and to salvage merchantable trees that must be removed. In addition, the
contractor will be required to protect trees outside of the construction area from damage. Cleared
forested areas along the interceptor route will be replanted with appropriate grasses, including a
fast-growing wetland seed mix for the wetland areas. At least 1 acre of the upland portion of the
right-of-way in the cleared forested areas will be planted with VA-70 lespedeza, Korean lespedeza,
ladino clover, and/or porridge pea to provide food and habitat for wildlife. Temporary construction
easements in the cleared forested areas will be replanted with grass and will not be mowed at all
once construction is complete, so as to protect small game nesting in the area and to allow for
natural revegetation. Slash or large trees from corridor construction will be placed in the
right-of-way corridor in forested areas as brush piles and downed logs at the request of property
owners from whom right-of-way is obtained.

Temporary or permanent vegetation will be planted on all bare soil in riparian areas at least within
10 days of ground disturbing activities. The contractor will be required to completely restore all
riparian areas within 15 working days or 90 calendar days following the initial ground disturbing
activity (including all pe,-nanent fertilizing, seeding, and mulching), which will comply with the
"seed as you to" strategy recommended by the NCWRC.
Coordination will be maintained with the North Carolina Department of Transportation throughout
the design of the Fuda Creek interceptor, and proper procedures for boring, tunneling, or
open -cutting the roads will be followed. Prior to construction, the applicable encroachment
agreements will be secured. In those areas where installation of the interceptor interferes with the
traffic flow, detailed traffic control plans will be developed.
The United States Fish and Wildlife Service concurs with the proposed project. The North Carolina
Water Quality Section, the North Carolina Division of Environmental Health, and the North
Carolina Division of Parks and Recreation concur with the proposed project. The North Carolina
Wildlife Resource Commission has recommended conservation measures that were considered in
the development of mitigative measures for the proposed project. The North Carolina Department
of Cultural Resources is not aware of any properties of architectural, historical, or archaeological
significance that would be affected by the project. The Mooresville Regional Office concurs with
the project. Other state agencies did not submit objections to this project.
G. Public Participation, Sources Consulted
A public hearing was held on September 18, 2003, on the proposed project. The presentation
included a summary of issues facing WSACC's wastewater collection system, the selected
alternative, and the project funding sources. The county's presentation indicated that sewer user
rates (based on 5,000 gallon -per -month average use) will generally increase as a result of this
project:

FROM: Ron Linville, Regional Coordinator
Habitat Conservation Program
DATE: June 7, 2004
SUBJECT: Review 201 Facilities Plan Amendment, Fuda Creek Interceptor, Water & Sewer
Authority of Cabarrus County (WSACC), Cabarrus County
We have reviewed the May 20, 2004 EA addendum submittal dated May 2004 received from
your office on May 26, 2004. The NCWRC has reviewed information provided by the applicant,
and field biologists on our staff are familiar with habitat values of the project area. We have also
reviewed new alignments for the sewer line provided by Leslie Jones with Camp, Dresser &
McKee. During the review, we received a copy of correspondence sent to Ms. Jones from Allan
Ratzlaff with the US Fish and Wildlife Service about the realignment and direct impacts
associated with the project. These comments are provided in accordance with provisions of the
Clean Water Act of 1977 (33 U.S.C. 466 et. seq.) and the Fish and Wildlife Coordination Act (48
Stat. 401, as amended; 16 U.S.C. 661-667d) and the North Carolina Environmental Policy Act
(G.S. 113A-1 through 113A-10; 1 NCAC 25).
The Carolina creekshell (Villosa vaughaniana), a state endangered species and federal species of
concern is present in the watershed. According to the documentation submitted for the project,
the Carolina heelsplitter (Lasmigona decorata), a state and federal endangered species is no
longer present. Mussel species are known to depend on forested areas to provide needed
ecosystem habitat functions as well as provide necessary water quality.
Based on our evaluation of the Facility Plan (May 2004), several positive land use activities have
been or will be provided in the proposed sewer service area. The following comments are
provided for your consideration:
1. The land use planning activities and ordinances proposed in the May 2004 Facility
Plan to address indirect (secondary and cumulative) impacts must be completed and
adopted for the service areas by all local governing bodies as described prior to
beginning construction. These adoptions should be equal in protective measures and
implementation. They should meet the intent expressed in the 201 Plan.
2. Proposed minimum buffers appear to be 30' (page 6-8). USGS maps and soil maps
are indicated methods for determining streams. Buffers should be no less than 50'

wide and extend from the top of the streambank. Larger buffers should be provided
as indicated in the 201 Plan (page 6-9) and to the maximum extent possible
throughout the service area. Professional stream determinations (delineations) must
be based on US Army Corps of Engineers and NC Division of Water Quality
jurisdictional (intermittent and perennial) identification criteria prior to local site plan
approvals. USGS maps and County Soil maps may be used for preliminary site
planning activities as long as jurisdictional delineations are accomplished by the
developer prior to any site clearing and grading. Impacts to jurisdictional waters and
wetlands must be avoided or properly permitted pursuant to Clean Water Act
provisions.
3. Existing wastewater package plants must cease to discharge upon completion and
activation of the Fuda Creek interceptor.
4. The utility line must apply for and receive a 404 Permit from the US Army Corps of
Engineers and adhere to NC Division of Water Quality 401 Certification conditions.
The installation of the sewer line must meet the installation requirements in both the
permit and the certification.
5. Due to suspected reduced wastewater flows and the amount of dye in area
wastewater, WSACC should move forward with removal of chlorine (and any de -
chlorination) and cessation of chlorine disinfection processes, including any stocking
and emergency use of sodium hypochlorite or similar chemicals. This should be
accomplished prior to plant upgrades or expansion to 54 Million Gallons per Day
(MGD).
6. Local governments should encourage and use conservation development practices
that preserve undisturbed natural areas along drainageways, streams and floodplains.
They should promote Low Impact Development (LID) techniques which, when
properly implemented, prevent unnecessary impacts to jurisdictional waters and
floodplains, maintain undisturbed wooded floodplains/buffers, maintain pre
development hydrographs, and mimic natural stream flow regimes.
The above comments generally reiterate our previous comments. Based on the positive, proactive
actions provided by local governments in the service area provided by the leadership of WSACC,
we do not believe that further comments on this project will be necessary. The proposed (and_
adopted) activities should reduce impacts to forested streams and floodplain areas which should
help maintain existing aquatic habitat functions and values; therefore, the NCWRC will not
comment further on the issuance of a FONSI for the Fuda Creek sewer interceptor.
Thank you for the opportunity to review and comment on this project. If you have any questions
regarding these comments, please contact me at 336/769-9453.

RE: Proposed Fuda Creek Sewer Interceptor Project, Cabarrus County
Dear Ms. Jones:
This correspondence is in response to your letter of November 19, 2003. The North
Carolina Wildlife Resources Commission (NCWRC) is authorized to comment and make
recommendations which relate to the impacts of.This project on fish and wildlife through
the Federal License of Water Resource Project Act (Federal Power Act-16 U.S.C. 79la et
seq.), and the Fish and Wildlife. Coordination Act (48 Stat. 401, as amended; 16 U. S.C.
661-667d).
The rare species survey performed for this project found and confirmed the presence of
Carolina ereekshell (P71/0.5a vaughaniana), a federal species of concern and a state
endangered species. This previously unidentified mussel in the Fuda Creels basin has
been reported to and confirmed as the Carolina ereekshell by the NC State Museum of
Natural Sciences and the US Fish and Wildlife Service.
Your letter request that we provide additional comments and/or recommendations
concerning the project_ It is our understanding that these surveys were provided as part
of the NC Environmental Policy Act review process. Accordingly, this new information
and any subsequent mitigative activities should be reported through the state
clearinghouse. Additional regulatory and resource agency comments may be required by
the clearinghouse.
Based on this new information, we are concerned about probable cumulative and
secondary impacts (CSI) to aquatic habitats associated with the sewer extension, and
increases development and imperviousness associated with the proposed sewer
extension(s)• Increased urbanization is likely to negatively impact aquatic environments
to the extent that the Carolina ereekshell and other aquatic life will be diminished or
extirpated from the basin. 'Therefore, we recommend that local plannin- and zoning
authorities follow the General recommendations found at
http://www.ncwildlife.or,-

In conclusion, this project should be resubmitted to the clearinghouse. Providing that
local ordinances adequately address cumulative and secondary impacts for species that
are federally listed species of concern, we should be able to concur or not object to the
sewer project. As stated above, the use of more stringent measures to protect listed
threatened and endangered species should provide improved assurances for the
environmental and economic wellbeing for future generations in this area ofNorth
Carolina. The implementation of Low Impact Development (LID) techniques in the
basin is recommended_ Additional information on LID measures can be found at

DATE: September 18, 2003
SUBJECT: Review of Water and Sewer Authority of Cabarrus County (WSACC) Fuda
Creek Interceptor Environmental Assessment EA), Cabarrus County
This office has received a letter (August 25, 2003) from Ms. Kelly Boone, PE concerning
the referenced Fuda Creek 201 Facility Plan Amendment and EA. The NCWRC has reviewed
information provided by the applicant, and field biologists on our staff are familiar with habitat
values of the project area. These comments are provided in accordance with provisions of the
Clean Water Act (CWA) of 1977 (33 U.S.C. 466 et. seq.) and the Fish and Wildlife Coordination
Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d).
Ms. Boone's letter responds to some project issues previously raised by the North
Carolina Wildlife Resources Commission (NCWRC). Ms. Boone indicates that the Cabarrus
County Subdivision Ordinance requires wetland delineation and that impacts modifying streams
are prohibited unless approved by the US Army corps of Engineers and the NC Division of Water
Quality. Additionally, it indicates that the county's sediment control process requires wetlands
and waters to be indicated on developer's plans and federal and state approvals are required prior
to plat approvals. The letter also indicates that the planning department defines perennial streams
as those indicated on USGS maps and that Concord will be extending buffer protection to
intermittent streams (Phase II stormwater permit). The Town of Harrisburg and Cabarrus County
will also extend buffer protection (minimum 30-foot) along perennial and intermittent streams.
The letter indicates that Cabarrus County Planning Department does not have the necessary
resources to field check every stream so they depend on soil maps and USGS maps.
In addition, the letter states that developers are required to provide minimum 50-foot
buffers pursuant to the Stream Overlay Zone Ordinance and floodplain modifications are
prevented through the Floodplain Damage Prevention Ordinance. Local municipalities require
pre and post runoff controls that maintain hundred year floodplain functionality. Concerning the
Rocky River Wastewater Treatment Plant, WSACC continues to evaluate reuse waters. WSACC
will re-evaluate the use of ultraviolet (ozone should also be considered) when the plant is
upgraded from 34 million gallons per day (MGD) to 54 MGD.

Fuda Creek Sewer 2 September 18, 2003
Based on our review of Ms. Boone's letter and our knowledge of the project area, it is
likely that we will not object to issuance of a Finding of No Significant Impact (FONSI) for the
Fuda Creek sewer providing the following conditions are included in the final FONSI:
1. Upfront jurisdictional water and wetland determinations will be accomplished by
certified US Army Corps of Engineers (COE) field personnel to ensure compliance
with the CWA instead of depending on USGS maps that are not satisfactory for this
purpose. Generally, these delineations are done by professional field consultants that
are hired by developers. They are not routinely accomplished by county or municipal
personnel. Soil maps and USGS maps may be used as tools for office evaluations.
All impacts to jurisdictional waters and wetlands should be properly permitted by the
COE and the Division of Water Quality prior to site clearing and any construction.
2. Undisturbed buffers will be provided for waters and wetlands as specified in Ms.
Boone's letter. We continue to recommend wider undisturbed 50-foot buffers on all
jurisdictional intermittent streams and minimum undisturbed 100-foot buffers on all
jurisdictional perennial streams throughout the county instead of wider buffers just
within river overlay areas. Much wider buffers are needed where listed aquatic
species are present. Stream and floodplain buffers should be preserved undisturbed
and natural to the maximum extent possible, regardless of buffer width.
3. Pre and post runoff hydrograph and floodplain conditions will be maintained as
described in WSACC consultant's documents. This activity should help reduce
secondary and cumulative impacts to aquatic resources providing it is adequately
integrated into development projects for commercial and residential developments.
The use of Low Impact Development (LID) techniques should be very helpful and
are known to be costs effective and land use efficient. Information on LID measures
can be found at «�.�« log` iuipactde� elepinent.or�.
4. WSACC will evaluate the use of non -chemical disinfection alternatives when the
Rocky River Wastewater Treatment Plant modifies their National Pollutant
Discharge Elimination System Permit or increases the amount of discharge flow. We
recommend the elimination of chlorine and de -chlorination chemicals for routine and
emergency operations at this facility if other options such as ozone or ultraviolet are
satisfactory as these chemicals can negatively impact aquatic environments.
We look forward to seeing the final FONSI document. The FONSI should include Ms.
Boone's agency correspondences. Thank you for the opportunity to review and comment on this
project. If you have any questions regarding these comments, please contact me at 336n69-9453.

RE: Proposed Fuda Creek Interceptor SEPA Review 201 Facility Plan Amendments
(DENR Project Number 1231), Cabarrus County
Dear Ms. Boone:
This correspondence is in response to your letter of June 13, 2003 concerning the referenced
environmental review. The North Carolina Wildlife Resources Commission (NCWRC) is
authorized to comment and make recommendations which relate to the impacts of this project on
fish and wildlife through the Clean Water Act of 1977, the Endangered Species Act, and the Fish
and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d).
Based on our review of your letter, we have the following responses in the order presented in
your letter:
l . Low Impact Development Techniques — Although Cabarrus County has revised zoning
regulations to allow forms of development that are thought to reduce the impacts of
development, no specific details are indicated comparing these efforts to Low Impact
Development (LID) techniques that have been used in other areas of the country and that
are used by other municipalities in North Carolina. Do these alternatives, in conjunction
with other types of development, actually protect aquatic ecosystems? The
environmental document should provide comparative analysis of what will actually occur
in the basins affected. Are vegetative buffers required for both intermittent and perennial
streams? What scientific criteria and accepted professional methodologies will be used to
identify jurisdictional waters? To be compliant with the Clean Water Act, Sections 404
and Sections 401, jurisdictional streams must be delineated and impacts to them avoided
and minimized. What local permit review or building permit requirements will be
provided to ensure that this occurs? Inri other words, is there a check off for pre site
planning delineations of jurisdictional waters and wetlands? It is our understanding that
Mecklenburg County's Surface Water Improvement and Management (SWIM) Program
may provide some buffers to some perennial waters, impacts to jurisdictional intermittent
and perennial headwaters above the SWIM acreage may be ignored even though they are
jurisdictional under the Clean Water Act. Again, what buffers will be required for
jurisdictional waters above the SWIM requirements throughout the service area?

Fuda Creek - Additk Information 2 July 15, 2003
2. Forested Buffers/Stormwater Runoff/Water Quality — Concerning the Cabarrus County
Flood Damage Ordinance to prohibit floodplain fill and the Mecklenburg County efforts
to provide stream restoration, we continue to recommend avoiding any fill within 100-
year floodplains to preserve stormwater management and flood storage capacity. Stream
and wetland delineation (items in number 1 above) are critical elements for stream buffer
protection activities. Simply stated, buffers are not likely to be provided where
jurisdictional waters are not properly identified. In addition, it does not appear that
stream restoration activities in urban areas can fully restore preconstruction hydrographs,
Aquatic habitats or water quality; therefore, sound site planning and preservation activities
are preferable and needed. It is our understanding that if the wastewater treatment
facility is adequate that it should be able to operate using alternate disinfection methods
instead of chlorine, including sodium hypochlorite and de -chlorination chemicals. As the
Rocky River has potential mussel restoration habitats and disinfection process chemicals
impact aquatic life, will the wastewater treatment disinfection be changed to a more
benign process like ultraviolet or ozone? Equal measures of protection should be applied
throughout the service area.
3. Secondary Impacts of Fuda Creek Interceptor — It is our understanding that development
densities and impervious area increases substantially with the provision of public sewer.
On -site sewage disposal sites typically produce less density and less imperviousness,
especially in areas with poor wastewater disposal soils. Obviously, additional care
should be provided when public or community sewer is provided to offset impacts of
imperviousness as well as typical curbing and guttering that are routinely associated with
public sewer and higher densities.
4. Mitigation of Cumulative and Secondary Impacts — The proactive approach to guide
long-range development in the area is appreciated; however, it is not clear how this will
ultimately preserve open space. Containing development closer to Harrisburg and
allowing wastewater connections on the north side of the Reedy Creek Interceptor may
avoid sprawl; however, does this avoid cumulative and secondary impacts downstream or
in developing watershed sub -basins in the county? LID methodologies are encouraged
even for low density developments where imperviousness approaches ten (10) percent.
The use of.grass swells instead of curbing and guttering is helpful. Concerning the
Cabarrus County Zoning Ordinances, it would improve the environmental document to
show the extent that the proposed guidance measures will actually promote long-term
water quality and preserve aquatic habitats.
We do not agree that impacts to wetlands and waters will be mitigated by zoning and.
floodplain ordinances although these may reduce some cumulative and secondary, .
impacts if they provide adequate safeguards and are implemented well. As previously
indicated, Clean Water Act jurisdictional delineations are needed_ Sediment and erosion
control measures should be used to avoid direct and indirect impacts to downstream
waters during construction. Again, it is important that jurisdictional waters be properly
delineated and buffered to prevent direct impacts from occurring. We do not disagree
that landscaping and vegetated buffers may help reduce erosion and soil loss that impact .
downstream aquatic environments.
We agree that Customized Development Standards, which may also be called
conservation development techniques, can be used to protect open spaces, rural
characteristics, and natural resources through compact development providing permanent
preservation is provided that allow ecosystems to remain functional and not fragmented.
Stream identification and buffer provisions should be incorporated into site planning in a
manner to prevent subdivisions, roadways and culverts from fragmenting aquatic and
terrestrial habitats that are functionally connected to area floodplains. It is essential for

Fuda Creek - Additk Information 3 July 15, 2003
sound environmental protection that these activities focus on protecting site specific
characteristics important to water quality and habitat in lieu of just aesthetic provisions.
Concerning the future expansion of the wastewater plant, we are informed that flow
allocations have been planned for the municipal service area already. We encourage the
reuse of wastewater within the basin and the use of an alternate non -chemical disinfection
process such as ultraviolet or ozone. The use of chlorine and de -chlorine chemicals
should be discontinued for both routine and emergency operations.
For your information, we share many of the concerns expressed by Mr. Alex Marks in his letter
of June 26, 2003. Please share your responses to the Division of Water Quality letter with us and
please fully evaluate the issues and concerns expressed above during the next environmental
document submittal. If these issues are adequately acknowledged in the document and sufficient
mitigation activities are provided that 1) identify jurisdictional waters, 2) preserve naturally
vegetated jurisdictional water and wetland buffers, 3) mimic predevelopment hydrograph
conditions to the extent practicable, and 4) preserve floodplain integrity, it is likely that we will
be able to concur .with (or not object) to the environmental assessment for the sewer project.
Thank you for the opportunity of commenting to you during the preparation of the project
environmental document. If you have any questions regarding these comments, please contact

Fuda Creek Interceptor Improvements and Environmental Assessment,
Water and Sewer Authority of Cabarrus County (WSACC), Cabarrus
County
This correspondence responds to a request by you for our review and comments
on the referenced project and attached Environmental Assessment (EA). These
comments are provided in accordance with the -provisions of the Clean Water Act of
1972, the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-
667d.) and the North Carolina Environmental Policy Act (G.S. 113A-1 through 113A-10;
1 NCAC 25).
The project includes the interceptor, pump station, and treatment plant projects
designed for the 50-year wastewater needs of Cabarrus County and neighboring regions,
including Harrisburg and portions of Mecklenburg County. Eastern Mecklenburg County
areas are included through an agr eirert with Charlotte -Mecklenburg Utilities
Department (CMUD). State Revolving Funds ($5.9 million) are being sought by
WSACC. Fuda Creek interceptor will convey wastewater to the Rocky River
Wastewater Treatment Plant (WWTP). This WWTP uses sodium hypochlorite for
disinfection. The Huntwick Package Treatment Plant is located on Fuda Creek too.
The Rocky River could provide potential suitable habitat or restoration habitat for
the Carolina heelsplitter (Lasin Bona decorata), a federally listed endangered species and
the Carolina Creekshell (Villossa vaughaniana), a federal species of concern. Both
species are listed as endangered by the State of North Carolina. These species have been
impacted as urban development has occurred in the region. The Carolina darter

((Etheostoma collis collis), a federal species of concern is also present in downstream
areas. The population projections (Table 2-1) indicate that 2,027 people are served with
the existing sewer. By 2050, 19,030 people will be served by the -sewer in the Fuda
Creek basin. Cumulative and secondary impacts (CSI) from increased development and
imperviousness to environmental quality should be anticipated. The document indicates
that the area south of Reedy Creek will be preserved as open space until such time as
development is planned. This is indicated as a method of encouraging development
closer to Harrisburg while Fuda Creek will be targeted for controlled residential
development.
The proposed project does not appear to have significant direct impacts to waters
or waters supporting listed species; however, it will increase indirect cumulative and
secondary impacts to downstream waters. As indicated in our previous scoping
comments, project proponents should evaluate low impact development (LID) techniques
(information available at wwtiv.lowimpactdevelopment.org). LID techniques should
positively alter anticipated stormwater impacts as LID methodologies retain runoff in a
manner that replicates pre -development runoff characteristics. This mimicry of natural
hydrology reduces the increase in pollutant loads above pre -development conditions. We
recommend and support the use of LID methodologies throughout the area to prevent or
reduce secondary and cumulative water quality impacts and habitat degradation.
We routinely encourage undisturbed forested buffers for all jurisdictional
headwaters (intermittent streams, perennial streams and wetlands) regardless of basin size
to provide urban wildlife habitat and functional, water quality buffers. Jurisdictional
headwaters must be professionally delineated prior to site planning and development to
ensure compliance with the Clean Water Act of 1972, Sections 404 and 401. In addition,
conservation development should maintain hydrologic conditions and preserve entire
floodplains as naturally forested areas to retain functionality and to ensure that flood
elevations do not increase from increased piping, imperviousness and stormwater runoff
impacts. Utility lines should be located away from streams and near the edge of
floodplains to protect streambank integrity and stream functionality. Alternative
disinfection processes like ozone and ultra -violet are recommended as these are generally
safer and less harmful to the environment. The use of chlorine for routine disinfection or
emergency disinfection purposes should be discontinued in waters that could provide
potential habitat for state and federal listed aquatic species as chemicals can have direct
impacts to survival of aquatic organisms.
As increase impervious and development in the Rocky River basin may cause
additional direct and indirect impacts within the basin, project proponents should
determine whether or not LID ordinance adoptions in the Fuda Creek service area can
preserve water quality and existing aquatic habitat values in the Rocky River basin. Any
such ordinances (or possibly local resolutions) should be provided for review by resource
agencies. The NC Wildlife Resources Commission has developed a CSI Memorandum
that can be accessed at
littp:/%ww,,v.ncwitdtife.or��%p�a07 WildlifeSpeciesCon/pg7c3 impacts pdf..This site
should be helpful in analyzing whether additional direct and indirect impacts may be

Fuda Creek Interceptor
May 2, 2003
anticipated within the Rocky River basin due to sewer improvements and increased
development. The present 201 Plan and Environmental Assessment (Section 5) does not
address cumulative and secondary impacts enough that we feel comfortable with
concurring with the project at this time. The document is unclear about whether or not
(and when) wastewater flows and treatment capacity increases will occur relative to the
Rocky River WWTP and how these flow increases might facilitate additional urban
growth. There is an -assumed expansion to 30 million gallons per day (MGD), 36 MGD,
and 54 MGD (Section 3.3). What direct and indirect impacts and precautions can be
anticipated relative to this proposed interceptor project?
We should be able to support the project providing adequate measures are
provided and implemented (or ensured by municipalities having jurisdiction) to reduce
impacts to the Rocky River basin. The information provided in the EA is not sufficient
for us to arrive at an informed decision. Project proponents should provide additional
information concerning implemented CSI techniques proposed that will ensure
minimized impacts to the watershed., Professional surveys for federal and state listed
species should provide valuable information concerning downstream aquatic
environments. This information should enhance this and future project reviews in the
area. We recommend that proponents look at the low impact website and our website as
well as this and previous comments by this agency as they provide additional
information. If there will be no additional CSI impacts to the Rocky River basin, we
simply need assurances and clarification that the interceptor project will not cause any
substantial cumulative or secondary impacts.
Thank you for the opportunity to review and comment on this project. If you or
project proponents have any questions regarding these comments or our concerns, please
contact me at 336/769-9453.

WATER AND SEWER AUTHORITY OF CABARRUS COUNT'
Technical Review Comments
201 Facility Plan Amendment
Fuda Creek Interceptor
Project No. CS370382-20
November 14, 2003
I. General
1. Please note that approval of the Facility Plan Amendment does not constitute approval of
sole source procurement. Plans and specifications must comply with N.C. General
Statute Chapter 133, Section 3, prior to their approval.
2. Please be advised that the Water and Sewer Authority of Cabarrus County should have an
approved user charge system and sewer use ordinance to provide for funding the sewer
system operation and maintenance and repayment of the SRF loan. Reimbursements
from a loan under the SRF program may not be issued until the user charge system and
sewer use ordinance have been approved.
3. Does the Water and Sewer Authority of Cabarrus County intend to make connection to
the sewer.: system mandatory? In order to maximize the public health and environmental
benefits of the project, it is strongly recommended that connection to the sewer system be
mandatory.
4. A loan from the North Carolina Water Pollution Control Revolving Loan Fund is
contingent on the review and approval of the proposed loan by the Local Government
Commission.
5. The owner and consulting engineer should be advised that after approval of the Facility
Plan Amendment, there are several construction project permits, approvals, certifications,
etc. that must be obtained before the project plans and specifications can be approved,
and before the project is advertised for bids. Therefore, it is strongly recommended that
preliminary work to obtain the following items, if applicable, begin as soon as possible:
a) Sedimentation and Erosion Control Permit from the Division of Land Quality, or a
letter from them stating that no permit is required for this project.
b) 401 Water Quality Certification and Army Corps of Engineers' 404 Permit for all
stream crossings, or a letter from the Army Corps of Engineers and from the
Wetlands 401 Certification Unit stating that none is required for this project.
c) A reasonable subsurface investigation must be made available to the contractor. If it
is not included in the specifications, the specifications must advise where a copy of
Page 1 of 5

the report can be observed. Typically, Construction Grants and Loans expects a
boring about every 500 feet and at each road crossing for line work, and at all major
structures like pump stations, aeration basins, and clarifiers.
d) NCDOT Encroachment Agreements and Railroad Encroachment Agreements.
Copies of these agreements must be provided in the specifications, or it must be
documented how all construction requirements, associated with the agreements, have
been incorporated in the plans.
e) Section 10 Permit for aerial crossings of navigable waters, or a letter from the Corps
stating that none is required for this project.
f) All construction easements, permanent easements, and rights -of -way. These
easements and rights -of -way must be shown on the plans.
II. Section 2 - Current Situation
1. Pages 2-6 and E-3: Please clarify the amount of existing flows in the Fuda Creek
interceptor. On page 2-6, the PER indicates that there is no current flow; however, on
page E-3 and Table E-2, a 0.26 mgd existing flow is identified in the down -stream
sector of 12527-12525. The 0.26 mgd existing flow should also be included in the
projected flow calculation on page 3-3.
2. The Clare Haven Pump Station flow should be discussed as existing wastewater flow
in the Fuda Creek basin.
III. Section 3 - Future Situation
1. Pages 3-1 and C-4: Provide the basis for the projected 350% population jump in Fuda
Creek drainage basin from 2,026 to 9,162 during 2000 and 2020. According to the
State Planning Office projections (http://demog.state.nc.usL% the Cabarrus County's
population growth rate in the same period of time would be 56.8%. Also, based on the
WSACC's Water and Wastewater Master Plan 2002 (on Appendix C, page C-4), the
projected population growth rates during this period of time for Harrisburg,
Kannapolis, Mt. Pleasant and Concord are only 154%, 92%, 66% and 5.1 %,
respectively.
2. Page C-5 or Table C-3: Please provide the basis for the projected extreme population
increase -- from 30 to 4,069 -- in the Mecklenburg County sub -basin from 2000 to
2025. Based on the referred 2002 WSACC Water and Wastewater Master Plan by
Black & Veatch (page 2-8, Table 2-3), the Mecklenburg County wastewater population
growth rate from 5,750 to 51,943 during 2000 and 2020 is a much lower percentage
growth rate.
3. Pages 3-3 and E-3: Please provide a 20-year industrial flow reserve, which should be
10% of current flows excluding UI.
Page 2 of 5

4. Figure 3-1: Please provide more information about the existing local private Huntwick
package wastewater treatment plant in the Fuda Creek basin. Will this, and/or other
local treatment facilities, affect the current flow estimate and the future flow
projections for 2025? Will the WWTP be taken out -of -service when the Fuda Creek
interceptor is installed?
TV. Section 4 - Alternatives
1. Provide an analysis of the potential open space and recreational opportunities
associated with this project.
2. Please confirm that all the proposed facilities comply with the NCAC 2H.0219
minimum design criteria.
3. Page 4-4: The information provided does not indicate that a STEP system would not
be a feasible alternative. Please provide a present worth analysis to compare the cost
effectiveness of the proposed gravity system and a STEP system to serve the Fuda
Creek basin.
4. Appendix E: Please provide more information on the gravity collection and
alternative routes to support "cost prohibitive" determination. Also provide
discussions on other alternatives, such as on -site treatment and STEP system.
5. Appendix E, page E-3: Confirm that the cost of rock excavation has been included in
the project cost -estimate.
6. Appendix F: Confirm that the costs associated with road crossings, stream crossings,
excavation, and dewatering have been included in the project cost estimate.
V. Section 5 - Present Worth Analvsis
1. Page 5.2 and Tables 5-1 and 6-1: Contingency presented in these tables is 10%
instead of 5% as indicated in the "Item" column. Provide an itemized cost estimate,
preferably in a separate table, to support the ".Construction Estimated Cost" listed on
Table 5-1.
2. Page 5-2, Tables 5-1 and 6-1: A 10% contingency is generally considered the low end
of the contingency range for a project in the preliminary design phase; a higher
contingency allowance should also be considered for a project where tunneling and
extensive rock excavation may be required.
3. Page E-7: Please provide the break -downs for the total 22,400 feet of anticipated
sewer lines in this project and clarify how many feet of the sewer lines are 12-inch,
21-inch and 24-inch, respectively.
Page 3 of 5

VI. Section 6 - User Charge and Financial Capacity
1. Table 6-2: Please clarify the SRF financing item of "Average Annual Interest": The
user charge calculation must be based on the first year of the SRF loan repayment.
The first year's payment must be determined based on equal principal payments over
the 20-year period and simple interest with declining annual payment. For example:
Loan amount = $5,911,000
Interest rate = 4%
Principal payment = $5,911,000/20 = $295,550
First year's interest = $5,911,000 x 4% _ $236,440
Total first year payment = $295,550 + $236,440 = $531,990
2. Table 6-2: Please demonstrate in a step-by-step fashion how the amounts were
derived for Capitalized Interest, Finance Cost — Revenue Bonds, and Average Annual
Interest. It is not clear how these items were calculated, based on the information
presented in Section 6 and footnote (c).
Table 6-3 and page 6-5: Please demonstrate in a step-by-step fashion how the listed
"Subtotal Interceptor Debt Service ($926,723)" was derived.
4. Table 6-4: Please incorporate the annual Median Household Income (MHI) of the
municipalities of Concord, Harrisburg, Kannapolis, and Mt. Pleasant in this table. If
expected user charges exceed 1.5% of the county's MHI, the project will be
-considered by EPA to be an "expensive" project and will warrant further evaluation
of alternatives. Therefore, options to reduce the total project cost and annual O&M
cost should be considered. Other options could include contributions from other
agencies, reduction in service area to include only.the most densely populated areas,
reduction in scope, etc. The monthly values of the 1.5% MHI in 2003 for the four
municipalities are $65.75, $92.74, $52.39 and $68.69, respectively.
2. Table 6-5: Please demonstrate in a step -by -stem fashion how the items of "Capital
Recover Fee" and "Interest Income" were derived on this table. Please explain why
the `interest Incomes" of the non -operating revenues for the four municipalities were
calculated at different rates.
3. Table 6-5: There appears to be a typographical, error for FY 2003 budgeted "Net
Available for Debt Service." Is the correct number $2,382,733 instead of
$2,332,733? Also, if needed, please correct the corresponding item of "Net Income."
4. Page 6-5: Please provide some information concerning the predicted effect of the
recent developments concerning Pillowfex/Fieldcrest as future flow estimates for the
industry.
Page 4of5

VII. Section 7 - Public Participation
1. Page 7-1: Please inform who the additional two members are, composing the nine -
member Water and Sewer Authority of Cabarrus County Board of Directors.
2. Once available, please provide a transcript or a detailed summary and an affidavit of
publication of the public hearing. Please provide a copy of the resolution from the
governmental unit agreeing to implement the selected alternative.

Review Comments
Water and Sewer Authority of Cabarrus County
Back Creek Interceptor
CS370382-21
On the plan view the pipe that connects from the existing 12-inch line to the 36-inch line is
shown on MH 4, but on the profile view this pipe is shown on MH 5. Please clarify.
Specifications:
1. The Agreement specifies the days for substantial completion as 450 days and final
completion as 480 days. The Bid Form specifies 518 days for substantial completion and
548 days for final completion. Please address.
2. The Department of Transportation and PSNC Encroachment Agreements refer to the
installation of a 24-inch sewer line. Please provide reviewed agreements or letters from
DOT and PSNC approving the modification to a 36-inch sewer line.
3. A copy of a DOT Encroachment Agreement for NC 73 was included in the specifications.
These agreement appears to be for a different project.
4. Section 13315, Part 2.0l.A.5 - Please note that in accordance with N.C.G.S. 133-3 and the
policy of the Construction Grants and Loans Section, the engineer can identify three
manufacturers that can meet the performance requirements, or establish a base bid with
three manufacturers, and identify a preferred piece of equipment as an alternate bid item.
The Owner can then select the least cost of the base bids, or the least cost of the alternate
bids, even if the alternate bid is more expensive than the base bid. There are times when
an owner or engineer has a preference for a specific manufacturer. State law allows you to
establish a base bid and identify the preferred product as an alternative bid item. This
allows the Owner to award the contract to the lowest of the base bids or the lowest of the
alternative bids even if the alternative bid is more expensive than the base bid. Typically,
our participation will be limited to the least cost of all alternatives. As a result of a
revision to GS 133-3, there are additional requirements that must be met in order to bid
proprietary alternates for projects advertised for bid after January 1, 2003. An excerpt
from the revised law states:

Mr. John Murdock III
Page 2
November 6, 2003
"... Specifications may list one or more preferred brands as an alternate to the base bid in
limited circumstances. Specifications containing a preferred brand alternate under this
section must identify the performance standards that support the preference. Performance
standards for the preference must be approved in advance by the owner in an open
meeting. Any alternate approved by the owner shall be approved only where (i) the
preferred alternate will provide cost savings, maintain or improve the functioning of any
process or system affected by the preferred item or items, or both, and (ii) a justification
identifying these criteria is made available in writing to the public.... "
For funded projects advertised after January 1, 2003, the Construction Grants and Loans
Section must receive confirmation, in writing, that the recipient has complied with these
additional requirements before approving and permitting the project and its subsequent
advertisement.
5. When specifying product manufacturers, at least three manufacturers should be listed,
along with the phrase, "or approved equal." If this cannot be done, please advise how
competition is offered so that the recommended units are not construed to be of a sole
source nature. The performance specifications are often written in a restrictive manner.
When a performance specification is used we ask the engineer to provide a list of
manufacturers that make equipment, which complies with the prpposed performance
specification. Some sections in the specifications where the three manufacturers are not
listed include Sections 15101.8, 15102.2, 15102.10, 15103.3 and 15107.5.

Environmental Review Commentsti
201 Facility Plan Amendment Fuda Creek Interceptor (April 2003) 2 Cp0
Project No. CS370382-20
August 18, 2003
Please amend the text of the Environmental Assessment where appropriate to include responses
to these comments.
I. Description of Proposed Proiect
1. Page 1-2, Description of Project Components: The Enviromnental Assessment states that
"The width of the new right-of-way for the Fuda Creek Interceptor will be 50 to 60 feet [and]
... The total permanent right-of-way that is needed for the entire project is approximately 28
acres." Please confirm whether this is in fact referring to a purchased right-of-way or a utility
easement along Fuda Creek.
II. Description of Existing Environment
1. Page 4-1, Land Use: While the Environmental Assessment describes the current land use
along the construction corridor and the surrounding areas, it needs to go further and discuss
how the current land use fits into the land use of the entire area in terms of conservation,
development, and ecological function. Also, please identify any current zoning classification
of the proposed pipeline route site and surrounding area.
2. Page 4-2, Wetlands: Please include a discussion of the specific existence of any wetlands
along or near the pipeline route. These wetlands should be indicated on the Exhibit A and B
maps. Please include a listing of the type, quality, and delineation of the wetland(s). Please
describe the primary function of the wetland(s) (e.g., flood control, wildlife habitat,
groundwater recharge), and other factors that indicate the relative importance of the function
to the total wetland resources of the area. The proposed project sites should be evaluated to
determine whether jurisdictional wetlands will be impacted.
Page 4-2, Prime or Unique Agricultural Lands: Please reference some source of information
for the statement that "No prime or unique agricultural lands are known to exist in the Fuda
Creek Interceptor project area."
4. Page 4-2, Air Quality: The Environmental Assessment should contain project area -specific
information on air quality. Please identify the area's air quality classification,
acknowledging if it is in transition and why. Please discuss any current source(s) of
emissions for the site, as well as any previous odor problems or complaints due to any
existing facilities.
Page 1 of 4

5. Page 4-3, Water Resources — Groundwater: If possible, please provide the proper names for
the "shallow" and "deep" aquifers discussed in the report. Please broaden the discussion on
groundwater to include use, quantity, and depth of the resource.
6. Pages 4-3 — 4-5, Shellfish or Fish and their Habitats: Please make this discussion more
relevant to Fuda Creek. Are there categories of shellfish beds/fish habitats along the project
corridor? Are these closed beds, highly productive areas, or spawning areas?
III. Environmental Consequences
1. The Land Use Impacts subsection appears to be the only section where indirect and
cumulative impacts of this project are addressed. In addition to the following specific
comments on the subsections of Section 5 — Environmental Consequences, please add to the
narrative of the other subsections under Environmental Consequences to address the indirect
and cumulative impacts of the project -that will'accompany development of the area. - _.
2. Page 5-1, Topography: Executive Order 11988 — Floodplain Management was promulgated
to avoid to the extent possible the occupancy and modification of floodplains by direct and
indirect support whenever there is a practicable alternative. Please amend this portion of the
Environmental Assessment to identify and evaluate any encroachments of the project on
floodplains.
3. Page 5-1, Soils: Please amend the narrative to include a discussion of the possibility of soil
contamination and possible contaminants (see comment #19). Please amend the discussion
of Mitigative Measures to address the action taken to reduce the risk of soil contamination
and/or remediate any contamination.
The Environmental Assessment acknowledges that soil will be excavated during this
project. How many cubic yards/feet will be moved? Please identify the off -site disposal
location for the soil that will not be returned to the trench as backfill after the pipe has been
installed.
The Environmental Assessment states that the "ground will be reseeded or repaved to match
conditions prior to construction." In the discussion of the consequences to wildlife and
natural vegetation, it is stated that approximately 25 acres of woodland will be cleared as a
result of this project and that "the cleared areas will be planted -with herbaceous species [and]
... Portions of the disturbed forested areas will be converted to a herbaceous or scrub -shrub
community as a result of the project." Replanting herbaceous communities and converting
the previously forested areas to a scrub -shrub community will not replace the previous
vegetative community, matching conditions prior to construction. Please amend the
statement on page 5-1 to reflect the difference in the post -construction habitat.
4. Page 5-1, Land Use: Will any local zoning or land use plans need to be amended to
accommodate the changes made possible by this project?
5. Pages 5-1 — 5-2, Wetlands: Please amend the narrative to address how the diversion of
surface water (as discussed in 5.10.1 Surface Water) may impact the existing wetlands. If
necessary, also amend the discussion of the mitigative measures to account for this impact.
Page 2 of 4

6. Page 5-2, Air Quality: Please confirm whether this project will increase odor levels or
increase the possibility for odor complaints.
7. Pages 5-2 — 5-3, Noise Levels: At what distance will increased noise levels be heard? Will
surrounding properties be affected by noise level?
8. Pages 5-3 — 5-4, Water Resources — Surface Water: The Environmental Assessment states
that the "Impacts to surface waters will occur during construction of the stream crossings.
Streams will be temporarily diverted to install the interceptor across the streams." However,
description of the specific impact(s) to the streams is not provided. Please describe how the
project will impact both surface water quality and quantity both during construction and
operation of the project.
9. Page 5-4, Water Resources - Groundwater: The Environmental Assessment states that
"There will be no significant impacts to groundwater quality as a result of any of the project
components. None of the project components will result in a significant disturbance." Please
discuss any possible impacts of the project on both groundwater quality and quantity.
10. Page 5-5, Wildlife and Natural Vegetation: The Environmental Assessment states that "The
wildlife species and habitats associated with the interceptor corridor will be temporarily
disturbed or displaced." Clearing 25 acres and replacing it with a scrub -shrub vegetative
community will not allow all of the wildlife that previously inhabited the corridor to return.
There will likely be a new, different wildlife community in this altered environment. Please
amend the narrative to address this.
12. Page 5-5, Introduction of Toxic Substances: Amend this subsection of the Environmental
Assessment to identify any toxic substances that could be introduced during construction or
operation of the project and identify how they will be used. For example, the potential exists
for petroleum products and/or hydraulic fluid to be inadvertently introduced to the
environment from the construction equipment. Discuss any measures that will be taken to
ensure that toxic substances will be treated in accordance will all appropriate regulations so
that there will be no significant environmental impact. Also, please amend the discussion of
mitigative measures to include those actions that will be taken to lessen the.impact of the
introduction of toxic substances at the project sites.
IV. Mitigative Measures
1. Please add to the discussion of Mitigative Measures to address those actions that will be
taken to lessen the project's impact upon shellfish or fish and their habitats.
V. Exhibits
1. Page 8-2 states that Exhibit A "may need to be modified based on results of field walk."
Please amend Exhibit A if necessary.
Page 3 of 4

2. Please amend both Exhibit A and Exhibit B to show wetland areas.
VI. Appendices
1. There appear to be some missing Appendices. The report goes from Appendix B to
Appendix H. Please either add appendices or relabel them.
VII. Agency Comments
1. There are external agency comments that need to be resolved. Please be reminded of the
comments from the North Carolina Wildlife Resources Commission, the North Carolina
Division of Environmental Health, and the U.S. Fish and Wildlife Service that have been
previously forwarded to you.
2. The comments received from the Water Quality Section Planning Branch have been
resolved, provided that the information contained in the July 22, 2003 from Ms. Kelly Boone
of CDM are contained in an updated 201 Facility Plan Amendment.

Technical Review Comments
201 Facilities Plan Amendment
Back Creek Parallel Interceptor
Project No. CS370382-21
August 8, 2003
I. General
1. Please note that approval of the Facilities Plan does not constitute approval of sole source
procurement. Plans and specifications must comply with N.C. General Statute
Chapter 133, Section 3, prior to their approval.
2. Please be advised that the Water and Sewer Authority of Cabarrus County should have an
approved user charge system and sewer use ordinance to provide for funding the sewer
system operation and maintenance and repayment of the SRF loan. Reimbursements
from a loan under the SRF program may not be issued until the user charge system and
sewer use ordinance have been approved.
3. Does the Water and Sewer Authority of Cabarrus County intend to make connection to
the sewer system mandatory? In order to maximize the public health and environmental
benefits of the project, it is strongly recommended that connection to the sewer system be
mandatory.
4. The owner and consulting engineer should be advised that after approval of the Facilities
Plan, there are several construction project permits, approvals, certifications, etc. that
must be obtained before the project plans and specifications can be approved, and before
the project is advertised for bids. Therefore, it is strongly recommended that preliminary
work to obtain the following items, if applicable, begin as soon as possible:
a) Sedimentation and Erosion Control Permit from the Division of Land Quality, or a
letter from them stating that no permit is required for this project.
b) 401 Water Quality Certification and Army Corps of Engineers' 404 Permit for all
stream crossings, or a letter from the Army Corps of Engineers and from the
Wetlands 401 Certification Unit stating that none is required for this project.
c) A reasonable subsurface investigation must be made available to the contractor. If it
is not included in the specifications; the specifications must advise where a copy of
the report can be observed. Typically, Construction Grants and Loans expects a
boring about every 500 feet and at each road crossing for line work, and at all major
structures like pump stations, aeration basins, and clarifiers.

C
d) NCDOT Encroachment Agreements and Railroad Encroachment Agreements.
Copies of these agreements must be provided in the specifications, or it must be
documented how all construction requirements, associated with the agreements, have
been incorporated in the plans.
e) All construction -easements, permanent easements, and rights -of -way. These
easements and rights -of -way must be shown on the plans.
II. Section 2 - Current Situation
1. Pages 2-1 and E-3: Please identify the condition of existing sewers and pump stations
for the subject project area. Please denote, on the map, the sections of the Back
Creek interceptor that have experienced surcharges under peak flow conditions.
Please provide a map to pin down the current surcharging sections.
2. Pages 2-4, 2-5, 4-5, and Appendices C and J: Please provide a location map, and
the sewer engineering calculation and design for the proposed Poplar Trails
Subdivision sewer project.
Please identify the un-sewered areas and population in the 201 Planning and Service
Area.
4. Page 2-5: Please confirm that there is no commercial contribution in the current
0.34 mgd flow. (Commercial flow should be based on water billing records minus a
10% consumptive loss).
5. Page 2-5: Please discuss any plans for work or current work that is being done to
reduce the sewer system inflow.
III. Section 3 - Future Situation
1. Page 3-3: Future industrial reserve is projected using the following criteria: 10% of
current flows excluding I/I. According to the information presented in the 2.6 Current
Flows, where the current flow is 0.34 mgd, I/I is 0.07 mgd. Therefore, the future
industrial reserve should be: (0.34 — 0.07) x 10% = 0.027 or —0.03 mgd.
IV. Section 4 - Alternatives
1. Provide an analysis of the potential open space and recreational opportunities
associated with this project.
2. Page 4-3 and Table 4-2: Please verify that the design slope for the section of
interceptor 13054-13060 is 0.005%, which is below the 36-inch line minimum design
grade of 0.05%. Please confirm that the proposed facilities comply with the
NCAC 2H.0219 minimum design criteria.
Page 2 of 4

3. Page 4-3: Please provide more information about the existing local private
wastewater treatment system in the Back Creek-Fuda Creek area. Will this, and/or
other local treatment facilities, affect the future flow projections for 2025? And will
these systems be out -of -service when the Back Creek interceptor is installed?
4. Page 4-5: The information provided does not indicate that a STEP system would not
be a feasible alternative. Please provide a present worth analysis to compare the cost
effectiveness of the proposed gravity system and a STEP system to serve the Poplar
Trails Subdivision.
V. Section 5 - Present Worth Analysis
1. Pages 5-1 and 5-2, and Tables 5-1 and 5-2: Please include the O&M and salvage
value in the present worth analyses for both parallel interceptor and Poplar Trails
projects. The.present worth analysis should include all the items listed below, if
applicable:
a) Capital costs.
b) Contingency.
c) Costs for engineering.
d) Start-up services.
e) Operation & Maintenance manual.
f) Land and easements, etc. Itemize these costs and include them in the present
worth analysis. Currently, the cost of land is generally not eligible under the SRF
program. Exceptions are made for land application of wastewater, land
application of sludge, and storage of wastewater.
g) Annual operation and maintenance costs and present worth of those costs.
h) Present worth of salvage value.
2. Page 5-1, 5.2 Present Worth Analysis: Provide some narrative to discuss and
compare the costs and benefits of two sewer line routes. The discussion should
include a recommended selection, and the basis for the selection.
VI. Section 6 - User Charge and Financial Capacity
1. Page 6-5: Please discuss why the Capital Improvement Plan projects of the Reedy
Creek and McKee Creek interceptors will not impose any financial impacts on the
customer rates. The user charges must be sufficient to repay any loan that is required
for the project's capital and operation and maintenance costs. Expected revenue
from user charge should be based on the first year's billable flow.
2. Pages 6-5 and 6-6: Please provide the latest annual Median Household Income
(MHI) for the municipalities of Concord, Harrisburg, Kannapolis, and Mt. Pleasant.
Also, please confirm that the proposed monthly user charges that result from various
projects in the four municipalities will not exceed 1.5% of their MHI's. Otherwise,
the project will be considered a high -unit cost project and will warrant further
evaluation of alternatives to reduce the total project cost.

I. INTRODUCTION:
This laboratory was inspected to verify its compliance with the requirements of 15A NCAC 2H
.0800 for the analysis of environmental samples.
II. GENERAL COMMENTS:
The laboratory was well organized and laboratory personnel were cooperative throughout the
inspection process. The laboratory continues to do a good job and no deficiencies were
observed.
III. DEFICIENCIES, REQUIREMENTS, COMMENTS AND RECOMMENDATIONS:
GENERAL LABORATORY:
RECEIPT DOCUMENTATION:
A. COMMENT: pH preservation is printed on sample pH documentation. The analyst needs to
put a check mark and initials in this box indicating that the testing was performed and identify
who conducted the testing. If the preservation testing is done in the field the sample collector can
check and initial the form. This will also include chlorine testing for ammonia, nitrate and nitrite
sample. Fecal coliform chlorine neutralization tested at the time the sample is set up. Metals pH
preservation is performed in the laboratory and needs to be documented and initialed.
METALS:
B. COMMENT (GENERAL): The. metals LCS (Q.C) is not digested. The LCS is to be treated as
if it were an analytical sample and is subject to all preparatory steps including digestion.

1W
Page 2 WSACC Rocky River Laboratory On -site Inspection Report
C. COMMENT (Pb, Cu, Zn, Fe, Ni, and Cr): On some occasions the reagent blank indicated
concentration levels at or above the lowest standard analyzed. The laboratory needs to
determine the cause and apply correction. It may that the PQLs for these metals are set too low,
or it may be that there are contamination problems.
FIELD PARAMETER ANALYSIS-:
Field parameters are analyzed at the following facilities under.the auspices of WSACC Rocky
River WWTP Laboratory N.0 certificate # 177: Muddy Creek, Odell School, Mt. Pleasant WTP,
and Bethel Elementary School.
COMMENT: Copies of bench worksheets are on -site, however instrument calibration logs were
not available for review at the time of the inspection. Copies of calibration sheets (selected at
random) are being forwarded for review.
D. COMMENT: (Settleable solids Mt. Pleasant) The start and stop time for this analysis is not
documented. Please record the time the sample is poured into the Imhoff cone and the time
when the reading is taken.
E. COMMENT: (All facilities) Temperature sample is collected, transported then analyzed. This
is usually accomplished, in about five minutes. Temperature readings .are to be instantaneous. If
the sample point is inaccessible, for a direct reading from the stream, collect a sample and
analyze for temperature immediately.
NOTE: This also applies to dissolved oxygen analysis.
IV. PAPER TRAIL INVESTIGATION:
Data and DMRs from December 2002, January and February 2003 were examined. Supporting
documentation and logs were also examined. No items other than those listed in the above
report were observed.
V. CONCLUSIONS:
Correcting the above cited deficiencies and comments and implementing the
recommendations will help this lab to produce quality data and meet certification requirements.
Please respond to all lettered comments.

This letter acknowledges that plans and specifications necessary to comply with the State
Revolving Loan funding requirements were received on July 7, 2003. Your project has been
assigned to Ms. Teresa Rodriguez, P.E. of the Construction Grants and Loans Section, and will
be reviewed .for technical adequacy and conformance to State laws, regulations, design
requirements, and good, sound engineering principles. You will be advised of any
recommendations, comments or other matters to be resolved, should this be necessary prior to
final approval.
A more detailed review is forthcoming. However, in an effort to expedite the review
process and to make funding available as soon as possible, we offer the following preliminary
review comments:
The description of the approved project in Permit No. WQ0020070, issued on
October 31, 2001, is different from the proposed project. Please complete and submit the
attached permit application for the modification of the existing permit, along with a
$400.00 fee.
Provide a copy of the Sedimentation and Erosion Control Permit from the Division of
Land Quality, or a letter from them stating that no letter is required for this project.
A reasonable subsurface investigation that must be made available to the contractor. If it
is not included in the specifications, the specifications must advise where a copy of the
report can be observed. Typically, CG&L expects a boring about every 500 feet and at

basins, and clarifiers. In the event that the information is not made available to the
contractor, then change orders associated with differing sites will not likely be determined
eligible for funding.
• The scope of work in the plans and specifications must be reasonably close to the scope
of work outlined in the approved Preliminary Engineering Report (P.E.R.), or the 201
Facilities Plan.
• If sewers are within a 100-foot radius of a well, then D.I.P. should be used with joints
tested to drinking water standards.
• If D.I.P. is used within a 100-foot radius of a well, it must not be any closer than 50 feet
to a public well, nor any closer than 25 feet to a private well.
• Manholes, air release valves, and valve boxes are not to be located within a 100-foot
radius of a well.
• If abandonment of the well is chosen by the local government, then provide
documentation/certification, signed by each affected homeowner, stating that they
understand their well must be abandoned.
• When abandonment of a well is chosen by the local government, provide an alternative
analysis that justifies the abandonment of each well.
• If well abandonment is chosen, the GW-30 form, "Well Abandonment Record", must be
included in the specifications. The well must be abandoned by a North Carolina certified
well driller in accordance with 15A NCAC 2C, Well Construction Standards. The Well
Abandonment form must be completed and submitted to the Division of Water Quality
Groundwater Section within 30 days of abandonment. The GW-30 form and other
information related to groundwater requirements can be downloaded from the following
web site: http://gw.ehnr.state.nc.us.
• If funding is desired, all addenda should be submitted to our office for review and
approval prior to opening of bids. Contractors should have all addenda at least seven
days prior to bid opening.
• Approval of all `or equals' must be by addenda prior to receipt of bids.
• Any private or public water supply source, including wells, any WS-I waters, or Class I or
Class H impounded reservoirs used as a source for drinking water within 100 feet of the
project must be shown on the plans.

• Any waters Classified WS-II, WS-III, B, SA, ORW, HQW, or SB within 50 feet of the
project must be shown on the plans.
• Confirm that all mitigative measures required by other permits and environmental
assessments have been incorporated in the plans and specifications. Provide a summary
of those measures in your written response.
• Advise if there are gas stations in the vicinity of the proposed project. If yes, then an
investigation should be performed on the soils and groundwater to determine if they are
petroleum contaminated. When the contamination exists, plans and specifications must
address how the contaminated soils and groundwater must be handled. All materials used
in petroleum -contaminated soils need to be compatible with petroleum.
• When petroleum -contaminated soil is found other routes must be considered. Please
advise what other routes were considered and advise why they were not excepted.
• Mobilization, if allowed, should not exceed 3% total and should not exceed 1% per
month.
These items should be resolved as soon as possible to prevent any delay in processing the
subject project. If there are any questions concerning the above, please do not hesitate to contact
me at [phone].

Division of Quality
SUBJECT: SEPA Review of DENR Project Number 1231, 201 Facility Plan Amendment
Fuda Creek Interceptor, Water and Sewer Authority of Cabarrus County
The Division of Water Quality (Division) has reviewed the 201 Facility Plan Amendment and
Environmental Assessment (EA) for this project. This project was recommended in the 2002
Water and Sewer Authority of Cabarrus County (WSACC) Water and Wastewater Master Plan
to provide sewer service for the western portion of the county. The service areas are the western
limits of the Town of Harrisburg and Cabarrus County, and a portion of eastern Mecklenburg
County. The interceptor line will be installed along Fuda Creek and include approximately 4.2
miles of 12 to 24-inch gravity sewer pipeline.
Section 6 addresses measures that WSACC will employ to mitigate the impacts of the project;
however, only mitigation measures to be employed by the town of Harrisburg and Cabarrus
County are provided. The document provides no information as to how impacts will be
mitigated in the Mecklenburg County portion of the project's direct and service area.
The Division requests an explanation as to the meaning of the following sentence on page 6-1,
"The area south of Reedy Creek will be preserved as open space until development occurs per
the land use planning." If development occurs on these lands, how will have they been preserved
as open space? Where are the areas to be preserved as open space in Reedy Creek?
The Division applauds the intention of the Harrisburg Area Plan to reduce urban sprawl by
directing development into the Fuda Creek basin rather than to the undeveloped areas of
Cabarrus County; however, mitigation must be provided in order to reduce the impacts of such
development on water quality. A*description of relevant plans, policies, and regulations that will
provide mitigation has not been provided. Elaborate on the commitment by WSACC to allow
wastewater connections only on the north side of the proposed Reedy Creek Interceptor. Provide
maps to clearly illustrate the areas discussed in this section of the EA.
The Division's memorandum of 24 February 2003 asked that the EA contain a discussion of
future land uses that would occur in the project's service area. The 201 Plan describes such uses

in Appendix C, Population and Growth, but not in the body of the EA. A map is also included
which depicts Cabarrus County's future land use. A version of this map needs to be provided in
the EA as well and at a scale which the project area can clearly be determined. What are the
anticipated future land uses for the Mecklenburg County portion of the project? Also raised in
the aforementioned Division memorandum but not discussed was the issue of how the NPDES
Phase H requirements would effect the service area. Finally, mitigation measures discussed for
impacts to streams and wetlands concern only the direct impacts of the project.
.At this time, the Division cannot support the document due to the limited -amount of information
it provides. Additional comments from the Division's Non -Discharge Permitting Unit are
attached.
Thank you for the opportunity to comment. Please contact me at 919-733=5083 x555 or by email

Fuda Creek Interceptor 2 May 2, 2003
((Etheostoma collis collis), a federal species of concern is also present in downstream
areas. The population projections (Table 2-1) indicate that 2,027 people are served with
the existing sewer. By 2050, 19,030 people will be served by the sewer in the Fuda
Creek basin. Cumulative and secondary impacts (CSI) from increased development and
imperviousness to environmental quality should be anticipated. The document indicates
that the area south of Reedy Creek will be preserved as open space until such time as
development is planned. This is indicated as a method of encouraging development
closer to Harrisburg while Fuda Creek will be targeted for controlled residential
development.
The proposed project does not appear to have significant direct impacts to waters
or waters supporting listed species; however, it will increase indirect cumulative and
secondary impacts to downstream waters. As indicated in our previous scoping
comments, project proponents should evaluate low impact development (LID) techniques
(information available at ww�v.lowimpactdevelopment.org). LID techniques should
positively alter anticipated stormwater impacts as LID methodologies retain runoff in a
manner that replicates pre -development runoff characteristics. This mimicry of natural
hydrology reduces the increase in pollutant loads above pre -development conditions. We
recommend and support the use of LID methodologies throughout the area to prevent or
reduce secondary and cumulative water quality impacts and habitat degradation.
We routinely encourage undisturbed forested buffers for all jurisdictional
headwaters (intermittent streams, perennial streams and wetlands) regardless of basin size
to provide urban wildlife habitat and functional water quality buffers. Jurisdictional
headwaters must be professionally delineated prior to site planning and development to
ensure compliance with the Clean Water Act of 1972, Sections 404 and 401. In addition,
conservation development should maintain hydrologic conditions and preserve entire
floodplains as naturally forested areas to retain functionality and to ensure that flood
elevations do not increase from increased piping, imperviousness and stormwater runoff
impacts. Utility lines should be located away from streams and near the edge of
floodplains to protect streambank integrity and stream functionality. Alternative
disinfection processes like ozone and ultra -violet are recommended as these are generally
safer and less harmful to the environment. The use of chlorine for routine disinfection or
emergency disinfection purposes should be discontinued in waters that could provide
potential habitat for state and federal listed aquatic species as chemicals can have direct
impacts to survival of aquatic organisms.
As increase impervious and development in the Rocky River basin may cause
additional direct and indirect impacts within the basin, project proponents should
determine whether or not LID ordinance adoptions in the Fuda Creek service area can
preserve water quality and existing aquatic habitat values in the Rocky River basin. Any
such ordinances (or possibly local resolutions) should be provided for review by resource
agencies. The NC Wildlife Resources Commission has developed a CSI Memorandum
that can be accessed at
littp://w,,wv.ncwildlife.ora/pgO7 WilcllifeSpeciesCon/pg76 impacts.pdf .This site
should be helpful in analyzing whether additional direct and indirect impacts may be

Fuda Creek Interceptor

anticipated within the Rocky River basin due to sewer improvements and increased
development. The present 201 Plan and Environmental Assessment (Section 5) does not
address cumulative and secondary impacts enough that we feel comfortable with
concurring with the project at this time. The document is unclear about whether or not
(and when) wastewater flows and treatment capacity increases will occur relative to the
Rocky River WWTP and how these flow increases might facilitate additional urban
growth. There is an assumed expansion to 30 million gallons per day (MGD), 36 MGD,
and 54 MGD (Section 3.3). What direct and indirect impacts and precautions can be
anticipated relative to this proposed interceptor project?
We should be able to support the project providing adequate measures are
provided and implemented (or ensured by municipalities having jurisdiction) to reduce
impacts to the Rocky River basin. The information provided in the EA is not sufficient
for us to arrive at an informed decision. Project proponents should provide additional
information concerning implemented CSI techniques proposed that will ensure
minimized impacts to the watershed. Professional surveys for federal and state listed
species should provide valuable information concerning downstream aquatic
environments. This information should enhance this and future project reviews in the
area. We recommend that proponents look at the low impact website and our website as
well as this and previous comments by this agency as they provide additional
information. If there will be no additional CSI impacts to the Rocky River basin, we
simply need assurances and clarification that the interceptor project will not cause any
substantial cumulative or secondary impacts.
Thank you for the opportunity to review and comment on this project. If you or
project proponents have any questions regarding these comments or our concerns, please
contact me at 336/769-9453.

Review Comments
Lower Coddle Creek Parallel Interceptor
Project Number CS370382-17
January 10, 2003
General:
Provide an updated cost estimate.
2. The contract documents that we review should include the following items:
a.
Payment Bond
b.
Performance Bond
C.
Notice of Award
d.
Notice to Proceed
e.
Change Order Form
3. The Notice of Award and Notice to Proceed should have places for the signatures of the
Contractor and the Local Government's Authorized Representative. The Consulting
Engineer's signature is not considered an acceptable alternative for the signature of the
Authorized Representative.
4. In accordance with G.S. 143-128.2, (effective January 1, 2002), a local government must
have a verifiable 10% goal for participation by minority businesses; five forms are
attached to assist in that documentation. These forms and the attached Guidelines should
be inserted in the contract documents and the contractors should be required to complete
the documents in accordance with the Guidelines.
Dispute Resolution must comply with G.S. 143-128(g). This statute allows the local
government to create their own Dispute Resolution policy which includes mediation, or
they may use the Dispute Resolution policy adopted on February 26, 2002 by the State
Building Commission (SBC). A copy of the SBC policy can be found on the web at:
http://interscope2.doa.state.nc.us/forms/2002Forms/sbc.Dis.rules.pdf.
6. A reasonable subsurface investigation must be made available to the contractor. If it
is not included in the specifications, the specifications must advise where a copy of the
report can be observed. Typically, CG&L expects a boring about every 500 feet and at
each road crossing for linework and at all major structures like pump stations, aeration
basins, and clarifiers. In the event that the information is not made available to the
contractor, then change orders associated with differing sites will not likely be
determined eligible for funding.

IM
7. The scope of work in the plans and specifications must be reasonably close to the scope
of work outlined in the 201 Facilities Plan. We understand that the pipe sizes may be
increased. The 201 Facilities Plan must be revised accordingly.
8. Show all wells within the vicinity of the project.
9. If sewers are within a 100-foot radius of a well, then D.I.P. should be used with joints
tested to drinking water standards.
10. If D.I.P. is used within a 100-foot radius of a well, it must not be any closer than 50 feet
to a public well, nor any closer than 25 feet to a private well.
11. Manholes, air release valves, and valve boxes are not to be located within a 100-foot
radius of a well.
12. If abandonment of the well is chosen by the local govermnent, then provide
documentation/certification, signed by each affected homeowner, stating that they
understand their well must be abandoned.
13. When abandonment of a well is chosen by the local government, provide an alternative
analysis that justifies the abandonment of each well.
14. If well abandonment is chosen, the GW-30 form, "Well Abandonment Record", must be
included in the specifications. The well must be abandoned by a North Carolina certified
well -driller in accordance with 15A NCAC 2C, Well Construction Standards. The Well
Abandonment form must be completed and submitted to the Division of Water Quality
Groundwater Section within 30 days of abandonment, with a copy to the Construction
Grants Section. The GW-30 form and other information related to groundwater
requirements can be downloaded from the following web site:
http://gw.ehnr.state.nc.us.
15. If funding is desired, all addenda should be submitted to our office for review and
approval prior to opening of bids. Contractors should have all addenda at least seven
days prior to bid opening.
16. Approval of all "or equals" must be by addenda prior to receipt of bids.
17. Any private or public water supply source, including wells, any WS-I waters, or Class I
or Class 11 impounded reservoirs used as a source for drinking water within 100 feet of
the project must be shown on the plans.
2

P1
18. Any, waters Classified WS-II,. WS-III, B, SA, ORW, HQW, or SB.-within 50 feet of the
project must be shown on the plans.
19. All existing utilities should be shown on the plans and in the profiles.
20. Clearly show how, horizontal and vertical controls are provided.
21. Advise if there are gas stations in the vicinity of the proposed project. If yes, then an
investigation should be performed on the soils and groundwater to determine if they are
petroleum contaminated. When the contamination exists, plans and specifications must
address how the contaminated soils and groundwater must be handled. All materials used
in petroleum -contaminated soils need to be compatible with petroleum.
22. When petroleum -contaminated soil is found, other routes must be considered. Please
advise what other routes were considered, and advise why they were not accepted.
23. Mobilization, if allowed, should not exceed 3% total and should not exceed 1% per
month.
24. Consider maintaining a 50-foot undisturbed vegetated buffer between streams and
construction activities, where possible, in order to minimize sedimentation into streams,
preserving riparian vegetation, and maintaining a travel corridor for wildlife.
25. Please provide documentation for any work that was completed, which was included in
the scope of the 201 Facilities Plan.
26. Please distinguish the work included in the 201 Facilities Plan which is relevant to the
Lower Coddle Creek project from the work which is relevant to the,Kings Grants project.
Currently, the 20.1 Facilities Plan lumps both projects'together. .
27. Please provide engineering calculations and a schematic of the wastewater flows at
different nodes in the combined interceptor and existing sewer system. Also, show that
the two diversion structures located at STA. 65+62.23 and STA. 207+71.30 are adequate
for the projected cross flow.
Plan Review Comments:
General Comments:
Please include, if present, all possible wetland -delineated areas on the plans. Note that in
delineated wetland areas, anti -seep collars are required at the downstream wetland
boundary, and every 150 feet up the gradient until the sewer line exits the wetland.

1MR
2. Please verify the source of the drinking water for the residential and commercial areas
adjacent to the proposed sewer. Locate any water main lines in the vicinity of the sewer.
If there are any wells within 100 feet of the sewer, please include their locations on the
plans.
When specifying the type of geotechnical fabric in the RipRap detail in several locations
on the plans, it appears that a sole brand/manufacturer was specified. Please note that in
accordance with N.C.G.S. 133-3, when a manufacturer is named, three manufacturers
should be named, and the phrase "or approved equal" should be used. In lieu of using a
brand name in the specification, you may choose to use a performance specification.
Should you choose to use a performance specification, we expect you to advise what
three manufacturers can comply with your performance specification.
4. It appears that most of the manhole rims are below the 100-year flood elevation. Please
confirm that the manholes are sealed. Vents are required about every 1,000 feet with the
one -foot distance above the 100-year flood elevation.
A recurring item under the Notes, lists two options regarding the crossing of the

B&V Project 130229.400
July 26, 2002
Phase 2 construction contractor mobilization areas are identified on the project
drawings.
B&V emphasized the requirements to maintain operation of existing facilities during
the improvements. The oxygen plant in particular requires special consideration.
Met-Lotepro will be of particular assistance to the contractor in planning the work.
Jim Cox of MZt-Lotepro (770-614-9008) was identified as a potential contact.
All bidders were reminded in considering their construction schedules for the project
that B&V's resident engineer's overtime onsite in excess of 8 hours per day and
40 hours per week must be compensated at a rate of $100/hr. In response to question
concerning potential work schedule of four 10-hour workdays, B&V agreed to amend
the requirement to restrict compensation of resident overtime to any hours in excess
of 40 hours per week. No compensation will be required for hours greater than
8 hours per day, if a total hours worked within the week is 40, provided all trades
work the same hours per day.
H. Questions and Responses
B&V commented that some questions had been received via voicemail in the days
prior to this conference. However, the terms of the bid documents require all
questions to be submitted in writing and all bidders were reminded that this
requirement would be enforced. Questions submitted by fax or via email will be
acceptable.
Questions and Responses from July 19, 2002, prebid conference:
1. Question: Four (4) concrete mixes are identified within the specifications. Which
mix should be used?
Response: Any of the four are acceptable. Each type varies based upon aggregate
size and water content, thus, the contractor should consider which type is desired for
the application and submit test results for approval. B&V noted that if test results for

one of the four mixes was already available from the contractor's chosen mix
supplier, that B&V would be able to consider the mix under the particulars of this
previous test data.
2. Question: Will you consider waiving the shrinkage test for concrete?
Response: No, because there is a water -containing structure involved. We need to
minimize shrinkage cracks.
3. Question: Appendix to specification Section 11150 from Robert L. Carlson includes
the specifics of the immersible pumps and drives. This appendix consists of a letter
proposal dated December 14, 2001, identifying 6 percent sales tax and not the current
state sales tax rate of 6.5 percent. In addition, the proposal states pricing is firm until
December 31, 2002, yet B&V has indicated the contract Notice to Proceed date to the
successful bidder may not occur until early 2003. Therefore, will the pricing for these
pumps and drives remain in effect?
Response: B&V will consult with Robert L. Carlson and issue revised allowance
pricing as needed.
4. Question: Does Cabarrus County have a higher sales tax than 6.5 percent and if so,
will it affect the Robert L. Carson sales price?
Response: B&V will consult with Robert L. Carlson and include higher sales tax as
needed in the revised allowance pricing.
5. Question: Should bids include all applicable taxes?
Response: Yes.
6. Question: Can B&V clarify the extent of patching needed to the secondary clarifier
bottoms as mentioned in specification Section 11435? Can B&V offer guidance on
the thickness of pea gravel concrete or grout to be added?
Response: B&V will clarify in Addendum 2.

peripheral devices needed to be installed within these computers which WSACC's
designated vendor will install. This will help to maintain warranty for the computers
and devices as a system.
10. Question: Do the subcontractors have to provide minority and women -owned
participation data at time of bid? ,
Response: The general contractor will need to coordinate with the subcontractors to
ensure all needed forms and supporting documentation are complete in accordance

12. Question: Will the generator required by specification section ever be operated for
peak shaving? If so, then the frequency of transfer between utility and generator

provided as part of the Phase 1 Improvements submittals will be made available to the
contractor under Phase. 2.
14. Question: The contract drawings show relief valves in the bottoms of each clarifier.
Is groundwater at the plant site significant enough of a problem that the contractor

201 Facilities Plan Amendment of May 17, 2002
Project No. CS370382-18
Dear Mr. Murdock:
The Construction Grants and Loans Section (CG&L) of the Division of Water Quality is
in receipt of Sandra Tripp, P.E. of Camp Dresser & McKee's letter of May 17, 2002 requesting a
revision to the size of the proposed interceptor lines in WSACC's Coldwater Creek 201 Facilities
Plan. The size of the lines would increase one size from 30-inch, 24-inch, and 18-inch to
36-inch, 30-inch, and 24-inch, respectively. An engineering amendment to the plan should be
submitted to include a justification for the revision, a description of the amendment and a revised
project cost. It does not appear that this amendment will necessitate recirculation to
departmental environmental reviewers; hence, only three copies of the amendment should be
submitted at this time. Justification for the revision should be based on CG&L's design criteria.
Upon receipt of the engineering amendment, we will complete our review of the project.
If you have any questions concerning this matter, please contact me at [phone] or
Mr. Rob Brown of our staff at [phone].

Plans Review Comments:
General:
When specifying the type of geotechnical fabric in the RIPRAP detail in several locations
on the plans, it appears that a sole brand/manufacturer was specified. Please note that, in
3

accordance with N.C.G.S. 133-3 and the policy of the Construction Grants and Loans
Section, the engineer must either identify three manufacturers who can meet the
performance requirements, or establish a base bid with three manufacturers, and identify a
preferred piece of equipment as an alternate bid item. The Owner can then select the least
cost of the base bids, or the least cost of the alternate bids, even if the alternate bid is
more expensive than the base bid. Grant eligibility is limited to the least cost alternative.
Attached is a copy of the legislation and the Construction Grants and Loans Section's
policy regarding N.C.G.S. 133-3
2. Please show and label the roads and access to the construction site clearly on the sheets
throughout the length of the proposed sewer construction.
3. Please label all Anti -Seep Collars in the elevation profile of the whole length of sewer.
4. Please show the permanent and construction easements clearly on the sheet and verify if
they are adequate for the sewer construction.
5. For all bank restorations, RIPRAP construction and stream crossing, please provide a
copy of the 401 Water Quality Certification to make sure that the activities are conducted
in concurrence with the requirements of Section 401.
6. Concerning the warning of danger from high voltage due to the power line, please list the
safety precautions needed to be taken in the specifications or plans.
7. The "Notes" shown on the right side of each plan sheet appear to indicate that the
sediment and erosion control features will be determined after the bid is awarded. Please
show those features in the plans prior to bidding. Advise how erosion control work will
be handled in the bid form.
Please show location of the service connections from the existing sewer, residential
buildings, and other construction features on the adjoining properties.

eligible and should be removed from the construction contract. All changes in quantities
or costs must be handled through changes in the contract. The contingency amount is to
be an excess amount in the budget, which is available to address changes in the contract.
Typically, we limit our participation to 5% of the bid amount on eligible construction
costs.

The interceptors proposed by this project will replace existing lines and not result in
additional flow to .the WSACC's Rocky River WWTP. All wastewater to be
carried by this new interceptor has already been permitted and is currently tributary
to the WWTP. Any additional flows will be permitted individually at the time of
each connection.
2. Confirm whether the proposed method and sequence of construction is
acceptable.
We have no comments to offer with regards to the proposed sequence of
construction.
If you have any questions regarding this matter, please advise.

Please be advised, the Water and Sewer Authority of Cabarrus County (WSACC)
has the capability of cleaning the 650 +/- feet of 30-inch, 560 +/- feet of 27-inch,
and 550 +/- feet of 18-inch sewer, as proposed within the above -mentioned
projects.
Cleaning of these line segments can, or will, be accomplished by either high-
pressure jetting/vacuuming, and/or mechanical cleaning methods as provided by
WSACC and/or local contract services. Both, the local contract service provider
and WSACC, have cleaning capabilities in excess of the 650 feet referenced. In
the event of clearing blockages, the equipment utilized by WSACC has the
capability of producing up to 4,000 psi of water pressure, at 20-25 gallons per
minute. WSACC feels that the combination of each of these capabilities should
provide sufficient cleaning of.these line segments, should the need arise.

Project Number CS370382-18
March 18, 2002
General
1. A loan under the SRF program cannot be awarded until the user charge system and sewer use
ordinance have been approved.
2. A loan from the North Carolina Water Pollution Control Revolving Loan Fund is contingent
on the review and approval of the proposed loan by the Local Government Commission.
Does the authority intend to make connection to the sewer system mandatory? In order to
maximize the public health and environmental benefits of the project, it is strongly
recommended that connection to the sewer system be made mandatory.
4. Please note that approval of the Facilities Plan does not constitute approval of sole source
procurement. Plans and specifications must comply with N.C. General Statute Chapter 133,
Section 3, prior to their approval.
Section 4
1. The Alternatives section should include a cost evaluation of all feasible alternatives including
alternative routes, on -site treatment systems, and Septic Tank Effluent Pump (STEP)
collection. If these alternatives are not feasible, narrative to that effect including an
explanation should be provided.
Section 6
1. (Reference Table 6-2) The effect of this project on user charge should be based on the first
year of the SRF loan repayment for Phase II of the project. The first year's payment must be
determined_ based -on equal principal payments over- the -20-year-period and simple -interest - - --.
with declining annual payment. For example:
Loan amount = $7,369,806
Interest rate = 4%
Principal payment = $7,369,806/20 = $368,490
First Year's interest = $7,369,806 * 0.04 = $294,792
Total First Year Payment = $663,282
Section 7
I. The Plan documents that a public hearing on this project was to be held in December of 2001.
A copy of the transcript from that hearing or a synopsis of the transcript should be provided.

configuration of the PLCs. A joint conference will be held with the successful
contractors after Notice to Proceed to discuss the coordination efforts.
Question: Section 11552, Paragraph 1-5.03, states: "The OCSS shall furnish and
install all electrical work required to properly interface and implement the control
modifications specified herein." Are you open to changing this?
Answer: Matt Marbois responded, "No." Matt indicated that B&V would have to
show one -line diagrams with sizes and number of wires, device locations, etc. As the
scope is unique with respect to controls, the specifications require the OCSS to be
responsible for furnishing and installation of the controls. Kruger and Lotepro may
be more knowledgeable and are expected to coordinate this division of installation
scope responsibility with the contractors during the bid period.
Question: On Instrumentation Questionnaire, if Lotepro, hypothetically, presents

FINDING OF NO SIGNIFICANT IMI'ACT ()FNSI)
Article I, Chapter 113A of the North Carolina General Statutes requires a project to be
subject to the requirements of the North Carolina Environmental Policy Act (N'CEPA) if
it involves a major agency action which will affect the environment. The proposed
project has been evaluated for compliance with the NCEPA and determined to be a major
action which will affect the environment and a State permit will be required.
Project Applicant: Water and Sewer Authority of Cabarrus County (WSACC)
Project Description: The proposed $6.7 million project is to be financed entirely
with local .funds and no state loans or grants are involved.
The proposed Adams Creek interceptor system consists of
installing 34,500 Lf of 8 to 30-inch pipes to serve the existing
development and the projected growth in the Adams Creek
drainage basin.
The review process indicated that significant adverse environmental impacts should not
occur if mitigative measures are .implemented, an.d an environmental impact statement
(LIS) will not be required. 'Elie decision was bas,Ld on information in the preliminary
engineering report and reviews by governmental agencies., An environmental assessment
supporting this action is attached. 11iis FNSI completes the environmental review record,
which is available for inspection at the State Clearinghouse.
No administrative action will be taken on the proposed project for at least thirty days after
notification that the FNSI .has been published in the NorthCarolinaEnvironmental
Bulletin.
Sincerely,
Kerr T. Stevens, Director
Division. of Water Quality

ENVIRONMENTAL ASSESSMENT
A. Proposed Facilities and Actions
Figures 1 and 2 identify the location of the proposed Phases I and II Adams Creek
collection/transport facilities.
Transport Facilities. The proposed project will be constructed in two phases to serve the
town of Mt. Pleasant and growth in the Adams Creek drainage basin. Phase I consists of
installing 15,5001.f. of 30-inch gravity lines along Adams Creek. Three additional lines (5,200
l.f. of 8-inch, 40011 of 10-inch, and 1,500 l.f. of 30-inch gravity pipe) will be installed to
connect to the 30-inch pipe so that the existing Food Lion, Summer Street, and Pasture pump
stations can be eliminated. The Phase II project will consist of installing 11,600 11 of 24-inch
interceptor along Adams Creek to connect to the Phase I 30-inch gravity pipe listed above. An
additional 30011. of 8-inch pipe will be provided to connect to the 24-inch line so that the
existing Mt. Pleasant High School package treatment plant can be eliminated. In addition to
installing the proposed interceptors to eliminate an effluent discharge and overloaded pump
stations, the proposed collection/transport facilities will facilitate growth in the Adams Creek
drainage basin. The flow from the proposed interceptors will be discharged into an existing
pump station, and treatment will be provided by WSACC's treatment plant. A FNSI was
signed September 3, 1999 for the approval of the Rocky River regional treatment plant to be
upgraded and expanded from 24 to 34 mgd.
B. Existing Environment
Topography and"Soils. The proposed project is situated in the Adams Creek drainage basin,
which is located in Cabarrus County. The topography is primarily rolling uplands with
elevations from 500 to 600 feet above mean sea level and slopes ranging from 1 to 40 percent.
Most of the upland soils are well drained with a clay or loam subsoil. Soils associated with the
streams and valleys are characterized by floodplain and wetland conditions. Septic tank
drainfields are primarily restricted due to impermeable soils in the Adams Creek drainage
basin.
Surface Water. Cabarrus County is located in the Yadkin -Pee Dee River Basin. Adams
Creek, a class "C" stream with a 7Q10 of 3.37 cfs, is the major stream in the'project area.
Adams Creek drains into Dutch Buffalo Creek, which flows into the Rocky River. According
to water quality data, the supporting use of Adams Creek is -threatened due to stream
degradation caused by growth and development in the area.
Water Supply. The town of Mt Pleasant receives its water supply from the Dutch Buffalo
Creek. Residents and commercial establishments that are not connected to the town's central
water system must rely upon groundwater.

V_
C. Existing Wastewater Facilities
The town of Mt. Pleasant is located in two drainage basins: the Adams Creek basin to the west
and the Dutch Buffalo Creek basin in the east. All of the town's flow is treated at the 24 mgd
Rocky River regional wastewater treatment plant. Wastewater collected in the Adams Creek
basin is pumped to the Dutch Buffalo Creek basin via three submersible pump stations owned
by Mt Pleasant. An additional pump station, which serves the Mt. Pleasant Elementary School,
is also located in the Dutch Buffalo Creek basin. The town has problems with overflows at the
two oldest pump stations (Summer Street and Pasture). Cabarrus County operates the 0.012
mgd package treatment plant which serves the Mt. Pleasant High School, and the effluent is
discharged into Adams Creek. The package plant is experiencing equipment problems, and
NPDES violations have been documented. Most of the town's collection system was installed
in the .1930's and the clay pipes with mortar joins are in poor condition. An infiltration and
inflow (I/I) analysis was performed and significant problems were documented. The town is
planning to implement a comprehensive sewer rehabilitation program.
D. Need for Proposed Facilities and Actions
The project area is experiencing a demand for residential development that is being driven by
the growth from the cities of Charlotte and Concord and Mecklenburg County. Accordingly,
the proposed interceptors will permit the collection of wastewater in the Adams Creek drainage
basin so that the flow can be conveyed efficiently to the Rocky River regional wastewater
treatment plant. The project will allow flows from the western portion of the town of Mt.
Pleasant to be collected by gravity, and; thus, eliminating three pump stations. The project will
also allow Cabarrus County to remove the effluent that is being discharged from the package
treatment plant serving the Mt. Pleasant High School. Therefore, the proposed project needs to
be constructed to provide the necessary collection/transport facilities to serve the existing and
future needs of the service area.
E. Alternatives Analysis
A facilities plan was prepared, and several choices were considered in the evaluation of
wastewater collection/transport facilities to serve the existing and future needs of the Adams
Creek drainage basin. The "no -action" alternative would require using individual septic tanks
to serve residential developments. However, the soils are not very conducive for utilizing
septic tank drainfields, and inadequately treated wastewater could cause public health problems
and degradation to surface waters. Package treatment plants are also.not an acceptable
alternative because the individual treatment systems with surface discharges do not generally
function well enough to protect water quality. The "no -action" approach was rejected due to
the wastewater limitations of meeting long-term growth needs in the Adams Creek drainage
basin. The preferred choice of action is to provide the necessary collection/transport facilities

to convey efficiently the wastewater generated in the Adams Creek drainage basin to the Rocky
River regional wastewater treatment facility. It is the selected alternative.
F. Environmental Consequences, Mitigative Measures
The proposed 24 and 30-inch gravity interceptors will be installed primarily along Adams
Creek and in proximity to unnamed tributaries. The 8 to 15-inch connecting lines are to be
located perpendicular and away from streams. Approximately 85 percent of the sewer
corridors consist of alluvial forest with trees estimated to be thirty to forty years old. The
remaining sewer corridors include agricultural fields, pastureland, and residential yards. The
interceptors will be located in the floodplain, and numerous stream crossings will be required.
Some of the stream banks are deeply incised with steep to vertical banks. There are no
documented wetlands that will be impacted except the steam crossings, and all construction
activities will take place in accordance with the Corps of Engineers' Nationwide Permit
Number 12 and the Division of Water Quality's 401 Water Quality Certification. The
Department of Cultural Resources reviewed the proposed plan and determined that there were
no properties of architectural, historic, or archaeological significance which would be affected
by the project. The U.S. Fish and Wildlife Service and the N.C. Wildlife Resources
Commission evaluated the proposed project and requested that mitigative measures be
implemented to avoid or minimize adverse impacts associated with the construction and
operation of the proposed wastewater collection/transport facilities. All of the review
comments from the agencies are attached. Responses to the comments and mitigative measures
are provided to assure the project will be implemented in a manner to eliminate or minimize
adverse impacts to the environment.
G. Public Participation, Sources Consulted
A public hearing was held May 20, 1999 on the proposed project to install collection/transport
facilities in the Adams Creek drainage basin, which includes the town of Mt. Pleasant. The
hearing covered problems of the existing package treatment plant and pump station facilities,
need for the proposed improvements, and cost to implement the selected alternative. No
opposition to the proposed project has been expressed, and a resolution has been adopted to
implement the proposed project.

NORTH CAROLINA DEPARTMENT -OF
ENVIRONMENT AND NATURAL RESOURCES
The following comments are offered with respect to the March 1999 EA submitted as part of the 201 Facilities
Plan for the Adams Creek Interceptor:
I. Alternatives Analysis. The use of pump stations and force mains with greater buffers from Adam's Creek
was not included in the Alternatives Analysis.
2. Rise in Flood Elevations. Section 4 B.L states no rise in flood elevations will result from this project. As a
secondary impact of development in this watershed a rise in flood elevation can be predicted. This rise is
directly related.to the increase in impervious area due to development.
3. Water Qualitv and Aquatic Habitat. The EA states "...the utility will be -placed. at least 10 feet from Channel
Banks; this action provides tors ade and bank stability." In most cases, a 10 foot placement of a sewer from
the channel bank results in destabilization of the creek slope and the potential for both short-term and long-
term significant impacts to the creek. 'To exponentially reduce this risk, it is- recommended that a 30 foot
buffer between the top of bank and the disturbed area be maintained for at least 90 percent of the project and
a 50-foot buffer between the top of bank and the disturbed area be maintained for at least 50 percent of the
project.
If you have any questions regarding these comments, please feel free to contact me at [phone] ext. 544.

Re: Adams Creek Interceptor, Cabarrus County
Additional Description of Site Conditions.
Dear Mr. Sutton:
This letter describes the existing conditions along the proposed Adam's Creek Sewer
route Soil & Environmental Consultants' project corridor evaluation. The entire length
of proposed route was traversed on foot. The approximate study area is shown indicated
in red on MAP 2. Project Location Map found within the Adams Creek Sanitary Sewer
Interceptor Environmental Assessment Document,
Phase One of the project was inspected first starting at SR 1006 and walking the project
area to the eaasting pump station at the lower end of the project near Dutch Buffalo
Creek This section (between SR 1006 and Dutch Buffalo Pump Station) consists
entirely of alluvial forest with the exception of the most eastern portion, which consists of
agricultural field used for crop production- Evidence of prior agricultural activities and
practices suggest that the entire length of the project area had at some tine been used for
crop production. Engineering and construction practices dictate that gravity lines be
located on the side of the channel that has less slope, in order to eliminate excessive
excavation for line installation. The estimated average age of trees within the
construction corridor is from 30 — 50 years old.
The Phase One corridor west of SR 1006, including routes to the Summer Street and
Pasture Pump stations. This portion of the sewer tine route consists mostly of alluvial
forest similar to the rest of the route with part ofthe proposed lime located within
agricultural field. At the the of the survey, this field was plowed and cultivated in corn
with a narrow buffer of young trees and saplings adjacent to Adams Creek.
The proposed corridor in Phase Two was found to be similar to Phase One, and is located
within alluvial forest along most of proposed route. Residential development exists
adjacent to the upper portions of the branch leading to the Food Lion pump station.. More
agricultural field and pasture is located near the corridor in the western portions of -Phase
Two north of Adams Creek.

Dear Mr. Sutton:
Subject: Adams Creek Interceptor, Odell School Gravity Sewer, and Upper Muddy Creek
Interceptor, Cabarrus County, North Carolina.
We received a copy of the subject plan amendments on September 1, 1999. The following
comments are provided in accordance with the provisions of the Fish and Wildlife Coordination
Act, as amended (16 U.S.C. 661-667e), and Section 7 of the Endangered Species Act of 1973, as
amended (16 U.S.C. 1531-1543) (Act).
The three plan amendments include construction of gravity sewer lines to tie into the future
Rocky River Interceptor, which will be treated at the Rocky River Regional Wastewater
Treatment Plant (WWTP). The future Rocky River Interceptor project was the subject of the
1998 Rocky River Regional 201 Facility Plan. The Odell School and Bethel amendments note
that because the individual lines are less than 3 miles in length they are not subject to the
requirements for preparation of an environmental assessment.
1. The Odell School Gravi , Sewer will consist of 6,600 feet of 8-inch PVC pipe
at the W. R. Odell Elementary School that will empty into the future Upper
Rocky River Interceptor. The design is for the gravity sewer line to be - .
constructed by Cabarrus County and maintained by the City of Concord. The
gravity sewer would eliminate the existing Odell School Wastewater
Treatment Plant (WWTP) (10,000 gpd capacity). The existing plant has
experienced compliance problems due to flow, ammonia, and total suspended
solids levels. The project is designed to handle projected build -out flows for
the service area.

2. _ The _Upper Muddy. Creek Interceptor will consist of;-12- through 18-inch _
gravity sewer lines at Bethel Elementary Schoolthat will empty into the Lower
Muddy Creek Interceptor. The project will eliminate the existing Bethel
Elemeritary School. WWTP (7,500-gpd)- The existing plant has experienced -
eompliance problems due to flow; amXrionia;. and fecal co'lforrn levels, .The`
project is_designed to handle proiected'b::uild=outflows-for"tlie-'service area.
. The 3Adams Creek Interce forwill.consist of 24-. throu h 30_inch
_ . . -_.... p g - gravity sewer
Tines ,with:8= and 10-inch branch.sewers.serviiig existing :facilities. The project
will eliminate three -existing pump stations, two -of which are over 50=years old
and subject to failure and overflows. The project will eliminate the
Mt. Pleasant High School WWTP (12,000 gpd), which has had NPDES permit
violations. The project is designed to handle projected build -out flows for the
service area. In the draft environmental assessment provided in the
amendment, we note that the sewer line will cross jurisdictional wetlands and
streams and will necessitate the clearing of approximately 33 acres of alluvial
forest. The sewer line corridors will impact stream flood plains along most of
the route.
We are pleased that these projects will result in the elimination of existing facilities that have
experienced problems with permit compliance, failures, and overflows. We believe the
consolidation and treatment of the sewer at a central advanced treatment plant will benefit the
receiving waters so long as the NPDES permit requirements are met. However, we have some
concerns about the potential direct effects of the construction of these new lines and the potential
indirect effects of the expanded service area. Further, the assimilative capacity of the
NPDES-permitted facilities that are being replaced by these three projects should not be
reassigned to other permits; rather, they should be credited as a permanent improvement in the
water quality of the receiving waters.
Even though these projects may fall below the minimum threshold for the preparation of an
environmental assessment, they each require at least a consideration of their potential impacts to
listed species. Therefore, we recommend that you consider the potential for listed species to be
affected by the construction of these three new sewer interceptors. The enclosed pages provide
an updated list of the federally protected endangered and threatened species known from
Cabarrus County that may occur within the area of influence of this proposed action. The legal
responsibilities of a Federal agency or its designated non -Federal representative under Section 7
of the Act are on file with the Environmental Protection Agency. The enclosed pages also
contain a list of species that are. currently under status review by the Service which may occur in
the project impact area.- These. species are not legally protected under the Act and are not subject
to any of its provisions, including Section 7, unless they are formally proposed or listed as
endangered or threatened. We are including these species in our response to give -you advance
notification. The presence or absence of these species in the project impact area should be
,addressed in any environmental document prepared for this project. Please use this updated -list
when preparing an endangered species, assessment for -each of the projects. -The minimal -

description of listed species in section LA should be revised to include the results of surveys,
methodologies, seasons, and personnel, as well as a determination of effect.
We believe_the indirect- effects of the project will certainly include fragmentation'of wildlife
habitat, loss, and encroachment on riparian areas, .and impacts to streams:aii& etlands due to - -
development within the expanded'service°areas: We believe -these indirecf'effects' - uld be
minimized by,the.adoption of mitigative measures similar to,those identified -for fhe Rocky River. -
Interceptor.
Please do not hesitate to contact Mr. Mark A. Cantrell of -our staff at 828/258-3939, Ext. 227, if
you have any questions regarding our comments. We have assigned Qur Log No. 4-2-97-143 to
this project; please refer to it in all future correspondence directed to us concerning this matter.

Dear Mr.. Sutton:
Subject: Lower Adams Creek Interceptor, Cabarrus County, North Carolina
We received a copy of the response to our September 8, 1999, comments on the Lower Adams
Creek Sanitary Sewer Interceptor and a revised Environmental Assessment. We have reviewed
these documents and are providing the following comments in accordance with the provisions of
the Fish and Wildlife Coordination Act, as amended (16 U.S.C. 661-667e), and Section 7 of the
Endangered Species Act of 1973, as amended (16 U.S.C. 1531-1543) (Act).
The project will involve construction of a gravity sewer line. The Lower Adams Creek
Interceptor will consist of 24- through 30-inch gravity sewer lines with 8- and 10-inch branch
sewers serving existing facilities. The project will eliminate three existing pump stations, two of
which are more than 50 years old and subject to failure and overflows. ,The project will eliminate
the Mt. Pleasant High School WWTP (12,000 gpd), which has had N:PDES permit violations. .
The project is designed to handle projected build -out flows for'tihe service area. In the
environmental assessment provided in the amendment, we note that the sewer line will cross
jurisdictional wetlands and streams and will necessitate the clearing of approximately 33 acres of
alluvial forest. The sewer line corridor will impact stream flood plains along most of the route.
We are pleased that this project will eliminate an existing facility that has experienced problems
with permit compliance, failures, and overflows. We believe the consolidation and treatment of
the sewer at a central advanced treatment plant will benefit the receiving waters as long as the
NPDES permit requirements are met. However, we are still concerned about the potential direct
effects of the construction of this new line and the potential indirect effects of the expanded
service area. Further, the assimilative capacity of the. NPDES-permitted facilities that are
replaced by this project should not 'be reassigned to other permits; rather, they should be credited
as a permanent improvement in the water quality of the receiving waters.

Listed species. Based upon a review of the project, consideration of the known species
occurrences, available habitat, and the procedures identified for- consideration of project
modifications, we concur that the project will not;affect endangered or threatened species and
their habitats. Therefore we: believe the requirerrients under Sectiorr 7. of the Act are fulfilled.
However, .obligations under, Section 7 of the Actmust=be reconsidered if:. (1) new information
reveals,impacts of this -identified action that may -affect listed:species or critical habitat in a
manner not previously considered, (2) his action is subsequently modified in a manner that Was.
not considered in this review, or (3) a new species is listed or critical habitat is determined that
may. be affected -by the identified action.
Riparian buffers. Because riparian vegetation will be removed during construction at stream
crossings, we recommend special measures to stabilize streambanks and restore riparian -
vegetation. We are still -concerned that in many cases the sewer line will be within 30 feet of
stream banks. This close proximity will undoubtedly result in streambank destabilization and
interrupt riparian functions. How will the WSACC address the certainty of future lateral
movements of the streams which might undercut or erode around the sewer lines? We
recommend development of a streambank monitporing and maintenance program to promptly
stabilize streambanks near the line throughout the life of this project.
Flood plain protection. Executive Order 11988 requires Federal agencies to consider and protect
flood plain functions. We believe the recent examples of flooding in eastern North Carolina
highlight the importance of avoiding the "... long- and short-term impacts associated with the
occupancy and modification of floodplains ..." and that we should "avoid direct and indirect
support of floodplain development...." In B.1. Hydrology and Floodplain Involvement, it is
noted that the interceptor will be constructed mostly within the floodplain. What date was the
floodplain study(s) for the area completed? Has additional impervious surface been developed
which might affect the current 100-year floodplain elevations? How much impervious surface is
there within the watershed? Does Cabarrus County have a limit on impervious surface area for
the watershed?
We appreciate the opportunity to provide these comments. If we can be of any assistance or if
you have any questions, please do not hesitate to contact Mr. Mark Cantrell of our staff at
828/258-3939, Ext. 227. In any future correspondence concerning this project, please reference

Re: USFWS LOG 4-2-97-143
Dear Mr. Cantrell:
We appreciate your wruments on the Adams Creek Interceptor project. The purpose of this letter
is to address your concerns and recommendations.
With respect to your comments pertaining to the section on endangered species:
Section L.3- Field Survey Methods has been revised to include the following information.
• Surveys for the Carolina heelsplitter, Lasmigona decorata, and Sohweinitz's sunflower,
HeRanthus decorata, were performed in September 1998 by Chris Huysman, Biologist for
Soil and Environmental Consultants, Inc.
Section L.3. Field Survey Methods further indicates, on page 14, that encompassing transects
were made of suitable habitat. No impact to their species is inferred by our statements on page 15
that "...habitat is not suitable for this mussel" and that `none were observed", referring to the
sunflower. If a more direct statement is needed please direct us. to state that no impact will occur,
as this is our opinion.
Detailed descriptions of the species are attached to the EA as appendices; these descriptions are
copied from the USFWS publication titled "Federally Listed Species in Eastern and Centeral
North Carolina" compiled by Ms. Kim Tripp.
We did not evaluate the impacts of this project on Federal Species of Concern because, as you
indicate, "these Species are not legally protected under the Act and are not subject to any of it's
provisions... ". We will take your advisement to the county and will conduct additional surveys
for any of these Federal Species of Concern are formally listed as threatened or Endangered prior
to construction.

Adams Creek Interceptor Environmental Assessment Comments
Dear Mr. Cole:
This is in reference to your letter dated May 10, 2000 to Reginald Sutton that provided
your review comments to the revised Adams Creek. Interceptor Project Environmental
Assessment (EA) that was submitted to the North Carolina Department of Environment and
Natural Resources (NCDENR) Construction Grants and Loan (CG&L) Section on March 22,
2000.
The EA for this project was initially submitted to CG & L in March 1999 as Appendix E
of the 201 Facility Plan Amendment for the Adams Creek Interceptor. Comments on the initial
EA were received from US Fish and Wildlife Service by letter dated September 8,1999. These
comments and recommendations were studied and responses were provided to Mr. Mark
Cantrell by letter dated October 19, 1999 from the Water and Sewer Authority of Cabarrus
County's (WSACC's) consultant. Since no further comments were provided, the EA was
revised and resubmitted to CG&L in March 2000.
Additional comments on the revised EA were also received from the NC Wildlife
Resources Commission by memo dated April 6, 2000 from Mr. Ron Linville. WSACC
responded to those comments directly in a letter dated May 12, 2000 (correspondence attached).
The NC Wildlife Resources Commission concurred with WSACC's response comments in a
letter dated May 26, 2000 (correspondence attached).
In response to your most recent comments in the May 10, 2000 letter and to further -
clarify the previous response, the following additional information is provided:
• Assimilative Capacity of NPDES Permitted Facilities to be replaced — It is our
understanding that the capacity of these facilities will not be reassigned to other facilities. In .
fact, the installation of this interceptor will eliminate the need to permit new individual
discharges within the basin as planned growth occurs in -the future. However, as you are
aware, NCDENR is the regulatory agency: directly responsible for issuance of NPDES
permits.

• Riparian Buffers — The project -design provides -for minimum construction corridors: The -
404 .permit requires minimum widths for wetland areas; however; no wetlands (0.0 acres)
are impacted by this project as documented by wetlands investigation and the 404 permit.
The sewer alignment for this project was selected to ensure minimum environmental impact.'
This included minimum stream crossings, crossing at or near right angles, and avoidance of
wetlands. As required by the project specifications and 404 permit conditions, all disturbed
banks will be restored to the original contours (with stable slopes) and revegetated with
native plant materials. Slopes up to the top of the ordinary water stage will be protected by
riprap.
Herbaceous vegetation planting on disturbed areas "seed as you go" strategy will be utilized.
The project specifications require a "seed as you go" strategy be utilized on bare soil
following ground disturbing activities. Strict adherence to the specified erosion control
measures and approved sedimentation and erosion control plans will be required of the
contractor. The project has received the required erosion control permit from the NCDENR
Division of Land Resources. WSACC performs streambank monitoring as part of its overall
interceptor maintenance program.
The design of this sewer interceptor provided for vertical and horizontal alignment that
minimized environmental impacts and was constructable. The alignment selected
minimized the number of steam crossings, kept the sewer below the streambed at stream
crossing (pipe below stream bottom), and provided for the maximum practicable buffer area
between the stream and the construction. The sewer alignment selected, excluding stream
crossings, typically provides for a minimum of 25-30 feet between the sewer line placement
and.the.stream top of bank. Approximately 1.0 percent of the project length has buffer of
greater than 100 feet between top of bank and sewer line placement, approximately 30
percent greater than 50 feet, and over 90 percent greater than 25 feet. The buffers provided
significantly exceed the minimum 404 permit requirements of 10 feet. Buffers of 100 feet
for the entire length of the project are not practicable from a constructability standpoint, due
to the excessive excavation depths that would be required.
• F000dplain Protection — The interceptor is located in the floodplain due to the fact that the
interceptor must follow the general path of Adams Creek to allow for gravity flow. It is our
understanding that the most current floodplain study for this area was completed by FEMA
in the early 1980's. No current inventory exists that detail the total impervious area located
within this watershed. Cabarrus'County has a Flood Damage Prevention Ordinance that all
new development must adhere to The,purpose of the Ordinance is to ".:.promote the public
health, safety, and general welfare and to minimize public and private losses due to flood
conditions..."

SUBJECT: State Clearinghouse Project No. 987: Adams Creek Interceptor 201 Facility Plan
Amendment; Cabarrus County Water & Sewer Authority
This correspondence responds to a request by you for our review and comments on the above
project. These comments are provided in accordance with the provisions of the Fish and Wildlife
Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d.) and the North Carolina Environmental
Policy Act (G.S. 113A-1 through 113A-10; 1 NCAC 25).
Before we can concur with a Finding of No Significant Impact (FONSI), the Environmental
Assessment (EA) in Appendix E needs to be modified to include the total linear feet and acres of major
streams and tributaries and total number of acres of wetlands to be impacted by the project.). Also,
Appendix E, Section 5 — MITIGATIVE MEASURES, must be modified to include the following
recommendations to off -set negative impacts to wetlands and streams impacted by the project:
l) Construction corridors should be no wider than absolutely necessary. The 401 certification
for Nationwide 12 stipulates that wetland construction corridors are not to exceed 40 feet and
permanent maintained corridors are not to exceed 10 feet except at access points.
2) Where stream crossings are necessary, sewer lines should cross streams at right angles to
minimize impacts to riparian areas. Disturbed stream banks must be restored to original contours
and revegetated with native plant materials such as silky dogwood (Corpus amonum), silky
willow (Sa1LY sericea) and hazel alder (Alnus serrulata). Riprap may be used to stabilize the bank
to the top of the ordinary water stage and vegetation (bioengineering) must be used above this
stave.
3) Sewer lines crossing streams should be buried in the stream bottom or attached to existing bridges
to maintain fish movement upstream and do Amstream'and prevent debris from collecting at the
pipe and causing a hydrologic change. We do not recommend installing priers in a stream
channel to support a sewer line.

4) If concrete will be used, work must be accomplished so that wet concrete does not contact stream
Water. This will lessen the chance of altering the stream's water chemistry and causing`a fish kill.
5) Where possible, an undisturbed buffer zone should be left between streams and all construction.
We prefer a -buffer zone of at least 100 feet'to control sedirnentation into.streams, provide shade;
and maintain a travel corridor for wildlife. Buffers should also be left -along intermittent drains or -
streams.
6) Temporarily disturbed wetlands must.be reseeded based on Corps of Engineers "Seedbed
Preparation and Seeding Specifications — Wetland Areas" outlined in Section 5.
7) . A portion df the upland right-of-way (minimum of one acre) should be planted with VA-70
lespedeza, Korean lespedeza, ladino clover, and/or partridge pea to provide food and additional
habitat for wildlife.
8) Slash and/or large trees available form corridor construction through forested and stream
corridors should be.placed along the permanent right-of-way in the form of brush piles and
downed logs to provide cover and nesting habitat for wildlife.
9) Right-of-way areas should not be mowed more than once every 2-3 years. Mowing should not
occur between April 1 through September 30 in order to avoid disturbing wildlife utilizing the
project corridor during the critical stages of nesting and rearing of young.
10) Stringent erosion control measures should be implemented where soil is disturbed and maintained
until project completion.
11) Temporary or permanent herbaceous vegetation should be planted on all bare soil within 15 days
of ground disturbing activities to provide long -tern erosion control. We prefer a "seed as you
go" strategy rather than allowing a large area to remain bare.

After a review of the responses to Mr. Joe Micueys's prcvio:is concerns (letter of April 12. 1999) and Mr.
Chris Huysman's response on October 19, 1999. this office continues to. be concerned that impacts from the project
can be further minimized or mitigated. Specifically, are there better alignments that further reduce impacts to the
associated ecosystems and streams? We are concerned that the consultant indicates that they will ask their client to
.,consider" previous comments and suggestions. The applicant should not simply "consider" or comply with
minimal standards for 401 Certifications when there may be better stewardship options. The recommendations
made by Mr. Mickey should be studied and a detailed response should be provided before a FONSI is issued.
Therefore, we recommend that the applicant and the consultant provide a detailed perspective and response on the
following prior to final approvals:
1) Whether or not buffer zones of 100' (or larger than minimal 10' buffers) are practicable and in which
specific areas they are not and why.
2) Whether or not slash and large trees from the corridor's forested areas can or will be utilized to provide
cover and habitat as previously proposed,
3) Whether or not the proposed planting and mowing .schedules can and will be followed,
') Whether or not a sediment and erosion control plan will be fiied with the Division of Land Resources,
i Whether or not an application for a 401 Certification will be requested (or specifics as to why such an
application is not necessary),
o) Whether or not a "seed as you go" strategy can and will be utilized,

Re: Comments and Recommendation Letter for State Clearinghouse Project No. 9
Creek Interceptor 201 Facility )'laic Amendment: Cabarrus County,Wata & Sewer
Authority ;
Dear Mr. Mickey:
Your comments and recommendations on the Adams Creek Interceptor Project are appreciated
and have been considered in the Amendments made to the Environmental Assessment. This
letter addresses the comments and recommendations of your letter dated April 12,1999.
Comment 1. Before we can concur with a Finding ofNo Signrji6ant Impact (FQNSI), the
Environmental assessment (EA) in Appendix E. needs to be modified to include the total linear
feet and acres of major streams and tributaries and total number of acres of wetland to be
impacted by the project. also, Appendix E Section 5 — Mitigative Measures, must be modified to
Include the following recommendations to off -set negative impacts to wetlands and streams
impacted by the project:
The Wetland Permits included in the document demonstrate that the channel impacts for
crossings are temporary and the minimum necessary for project completion, and that there are no
wetland impacts (Appendix 4). As for recommendations 1-11, please refer to Appendix 6,
Nationwide Permit 12 Package, including NW 12 Conditions and 401 General Certification
Conditions. By law, all conditions must be met, and a statement of compliance with all
regulations will be submitted to the proper agencies within 30 days of the completion of the
Project.
Comment /Recommendation 5: Where possible, an undisturbed buffer zone should be left
between streams and all -construction . We prefer a buffer zone of at least 100 feet to control
sedimentation into streams, provide shade, and maintain a travel corridor for wildlife. Buffers
should also be left along intermittent drains or streams.
The project will comply with all 401 General Certification Conditions (Appendix 6). The..
proposed sewer line placement is typically a minimum of 25 feet from the top of the channel:
bank, and the construction corridor is located a minimum of 10 feet from the top of the channel
bank (in compliance with the above referenced found wid'ain Appendix 6) with the exception of
_ _ channel crossings. Channel crossings fall within angles specified by the General Conditions:- - -

Comment Recommendation / 8: Slash and/or large trees available from corridor construction
. Though forested: and strewn corridors should be placed along the permanent right=of way in the
form o rus pi es and downed logs to provide -covet and nesting habitat for wildlife.
This recommendation is being considered and brought to the attention of the Water- and Sewer-
Authority,of Cabaarrus County.. However; this practice raises some` concern of moderate"fire
hazard. .
.Comment/Recommendation 9: Right -of -way -areas should not be mowed -more than once every -
2-3 years,. Mowing should not occur between April I through September 30 in order to avoid
disturbing wildlife utilizing the project corridor during the critical stages of nesting and rearing
of young.
This recommendation is being considered and brought to the attention of the Water and Sewer
Authority of Cabarrus County for feui`bility.
Comment/Recommendation 10: Stringent erosion control measures should be implemented
where soil is disturbed and maintained until project completion
The project will comply with all 401 General Certification Conditions (Appendix 6).
Comment/Recommendation 11: Temporary or permanent herbaceous vegetation should be
planted on all baresoil within IS days of ground disturbing activities to provide long-term
erosion control. We prefer a "seed as you go"strategy rather than allowing a large area to
remain bare.
The project will comply with all 401 General Certification Conditions (Appendix 6).
Thank you for your time. Please feel free to contact us with questions.

Subject: Adams Creek Interceptor Environmental Assessment Comments
Dear Mr. Linville:
This is in reference to your memorandum dated April 6, 2000 to Reginald Sutton that
provided your review comments to the Adams Creek Interceptor Environmental Assessment
(EA). You noted concerns relative to the October 19, 1999 response provided by the Water and
Sewer Authority of Cabarrus County's (WSACC's) consultant to Mr. Joe Mickey's previous
comments of April 12, 1999. It was suggested that the recommendations made by Mr. Mickey
should be studied and a more detailed response provided. The comments and recommendations
from Mr. Mickey were studied and responses were provided as outlined in the October 19, 1999
letter.
However, to further clarify.the previous response the following additional information
is provided:
• Comment 1 — Maintenance of minimum construction corridors: The project design provides
for minimum construction corridors. The minimum widths for wetland areas are required
by the 404 permit; however, no wetlands (0.0 acres) are impacted by this project as
documented by wetlands investigation and the 404 permit.
Comment 2 — Minimize impacts at stream crossing: The sewer alignment for this project
was selected to ensure minimum environmental impact. This included minimum stream
crossings, crossing at or near right angles, and avoidance of wetlands. As required by the
project specifications and 404 permit conditions, all disturbed banks will be restored to the
original contours (with stable slopes) and revegetated with native plant materials. Slopes
up to the top of the ordinary water stage will, be protected by riprap.
Comment 3 — Vertical location of sewer along streambed at required crossings: The design
of the sewer is such that all sewer crossings are located below the streambed (no aerial
crossings).
• Comment 4 — Use of concrete: Ductile iron pipe will be used and no concrete will be used
in the streambed. At stream crossings, outside of the flow channel, buried concrete piers
_su2s'��29
Fi 704 '36 3205

Mr. Ron Linville
Adams Creek EA

will be utilized for buoyancy control. Project Specifications require that construction
techniques be used that will preclude any concrete from coming in contact with the stream
water.
Comment 5 — Undisturbed buffer area between stream and construction: The design of this
sewer interceptor .provided for vertical and horizontal alm ignent that Minimized
environmental impacts and was constructable. The alignment selected -minimized the
number of steam crossings,. kept the sewer below the streambed at stream crossing (pipe
below stream bottom), and provided for the maximum buffer area -between the stream and
the construction. The sewer alignment selected, excluding stream crossings,. typically
provides for a minimum of 25-30 feet between the sewer line placement and the stream top
of bank. Approximately 10 percent of the project length has buffer of greater than 100 feet
between top of bank and sewer line placement, approximately 30 percent greater than 50
feet, and over 90 percent greater than 25 feet. The buffers provided significantly exceed the
minimum 404 permit requirements of 10 feet. Buffers of 100 feet for the entire length of
the project are notpracticable from a constructability standpoint, due to the excessive depths
that would be required.
• Comment 6 — Temporarily disturbed wetlands: The project does not impact wetlands;
however any temporarily disturbed wetlands will be re -seeded based -on the 404 permit
requirements of the Corps of Engineers.
• Comment 7 — Seeding in upland right-of-way: The project specifications require portions
of any upland right-of-way (minimum of one acre) be planted with Lespedeza, clover, or
partridge pea to provide additional habitat for wildlife.
• Comment 8 — Slash and/or large trees placed along permanent right-of-way: The project
specifications require that, where practicable, this slash material be placed along the
permanent right-of-way. Please understand that we do not purchase land in fee simple but
rather purchase a right-of-way/easement. Therefore, in the interest of maintaining good
relationships with property owners, we strive to accommodate all reasonable requests from
these property owners. Therefore, if a property owner strenuously objects to slash being
placed at the edge of the right-of-way, we do not feel that it is reasonable to force this issue.
Therefore, the location and extent of placement will be based upon property owner right-of-
way commitments, among other factors.
Comment 9 — Right-of-way maintenance mowing schedules: Where practicable, project
right-of-ways will be mowed on a frequency of every 2-3 years. Generally, mowing will
not occur between April 1 and September 30. Deviations from this policy will depend upon
conditions attributable to weather, emergency maintenance, and required regulatory agency
inspections.
• Comment 10 — Implementation of stringent erosion control measures: Strict adherence to
the specified erosion control measures and approved- sedimentation and erosion control plans
will be required of the contractor. The project has received the required erosion control
permit from the NC DENR Division of Land Resources.

Mr. Ron Linville
Adams Creek EA
May 12, 2000
Page 3 of 3
• Comment 11 — Herbaceous vegetation planting on disturbed areas "seed as you go" strateQy:
The project specifications require a "seed -as you go" strategy be utilized on bare soil
following ground disturbing activities.
In addition to the above, you requested that the following also be provided: 1
• Whether or not an application for 401 certification will be requested? The 404 construction
permit for the project has been obtained from the Corps of Engineers, which includes
applicable 401 water quality certification.
• Whether or not a sediment and erosion control Alan will be filed with the Division ofLand
Resources? The sediment and erosion control plan for this project has been submitted to
the Division of Land Resources and a permit has been issued.
• Whether or not the United States Fish and Wildlife pService concurs with the measures
rovided to protect endangered or threatened species? A response dated October 19, 1999
was provided to the US Fish and Wildlife Service relative to their environment review. No
additional information has been requested.
In summary the 201 Facility Plan for the Adams Creek Interceptor project was initially
submitted to Construction Grants in March 1999. At that time the EA was distributed by
Construction Grants to the appropriate agencies for comment. The project was designed to
minimize the potential environmental impacts, the selected alignment impacts no wetlands area
(0.0 acres), and the necessary responses and/or revisions to the EA have been made to address
review comments.
Your help in finalizing the environmental review process and having the FONSI issued
is appreciated. If necessary, we are available to meet with you at your convenience to further
discuss this matter.

FOR THE _
construction and operation of approximately 16,769 linear feet of 36 inch sewer
interceptor line, 40 manholes and associated appurtenances; -
pursuant to the application received June 15, 1998 and in conformity with the project
plan, specifications, and other, supporting data subsequently filed and approved by the
Department of Environment, Health and Natural Resources and considered a part of this
permit.
This Permit shall be effective from the date of issuance until rescinded, and shall be
subject to the following conditions and limitations:
1. This Permit shall become voidable unless the facilities are constructed in

Subject: Rocky River Regional WWTP Expansion
201 Facilities Plan
Preliminary Engineering Report
Cabarrus County
Per your request, a review has been conducted by the staff of this Office of
the subject 201 Facilities Plan commissioned by the Water and Sewer Authority of
Cabarrus County (WSACC). This report details the planned expansion of the
subject WWTP to 34.0 MGD (initial expansion) and 54.0 MGD (ultimate build -out).
Based on current flow projections, the existing WWTP is expected to reach 90% of
it's current hydraulic capacity by the year 2002. With approximately 12,000 linear
feet of sewer line permitted during the past 1.2 months, and the nearby area
experiencing significant growth, flows are expected to .significantly increase at the
WWTP.
In evaluating the results.of the 201 plan, it should be noted that a series of
meetings have been held with DWQ staff and staff from the WSACC to discuss
current permitting issues and WWTP effluent expectations once expansion is
complete. Any changes to the speculative effluent limitations discussed during
these meetings may. necessitate changes to the proposed WWTP expansion
design. -Significant plant changes are not, however, .expected.
If you have any questions regarding this matter, please advise.

Section 1
Executive Summary
The Water and Sewer Authority of Cabarrus County, North Carolina, (WSACC)
owns and operates the Rocky River Regional Wastewater Treatment Plant (RRRWWTP),
serving the City of Concord, City of Kannapolis, Town of Harrisburg, Town of
Mt. Pleasant, and Cabarrus County. RRRWWTP began operation in 1979 with a design
treatment capacity of 24 million gallons per day (mgd).. Ninety percent of the existing
capacity of RRRWWTP (21.9 mgd) has been projected to be reached near .the year 2002.
WSACC has planned to provide upgrades and expansion to the facility to continue to
provide regional wastewater service to Cabarrus County and portions of Mecklenburg
County through agreements with Charlotte -Mecklenburg Utility Department (CMUD).
— The Wastewater Treatment and Collection System 201 Facility Plan prepared by
Camp Dresser and McKee (CDM) to address construction of Water and Sewer Authority
of Cabarrus County's proposed Lower Rocky River Relief Interceptor and Pumping
Station was submitted March 1998, and supplements addressing comments were submitted
August 1998 and September 1998. An engineering amendment prepared by
Black & Veatch LLP was submitted August 4, 1998. The amendment addressed the
i headworks facility project which was included in the March 1998 201 Plan as part of
plant upgrades.
This document addresses the expansion of the Rocky River Regional Wastewater
Treatment Plant. Information supplied is in addition to the information provided in the
previous plan. Information provided includes the following:
• Updates to current situation.
• Updates to future situations.
• Discussion of alternatives and present -worth evaluation between selected
alternatives for the wastewater treatment facility.
• Capital costs for the current project and for the 20-year project.
• Update to user charges and financial capability.
• Environmental assessment for the wastewater treatment plant project. .
The facility will be upgraded and expanded to 34 mgd, which is less than the 20-year
planning' capacity of 44 mgd. The phasing of plant expansions to meet the 20-year
capacity is justified due to the high growth rate expected over the next decade.
- WSACC is seeking State Revolving Funding for the upgrade and expansion of
RRRWWTP. The preliminary project cost opinion is $20.5 million.

processes include influent pumping with bar screens, primary clarification, Step I
carbonaceous aeration (pure oxygen), Step I clarification, return activated sludge pumping,
Black & Veatch
February 3, 1999
2-1 WSACC—Rocky River Regional WWTP
Upgrade and Expansion

Step II nitrogenous aeration (pure oxygen), Step II clarification with return activated
sludge pumping, and effluent disinfection. The existing solids train unit processes include
gravity thickening, sludge conditioning (polymer addition), centrifugation, incineration,
and waste ash basin storage. Design projects expected to be completed by mid-2000
include a second (remote) influent pumping station and a new headworks facility. The
pumping station and headworks facility were discussed in detail in the March 1998 Plan
and August 1998 Engineering Amendment.
An evaluation of the existing process units and unit capacities was included as a part
of the Process and Hydraulic Study performed by Black & Veatch LLP. A copy of the
"Process and Hydraulic Study Summary Report," October 1998, is provided in
Appendix B. Table 2-2 summarizes the existing unit processes and their capacities. The

The report also addresses the required process units for a planned build -out of the
facility to 54 mgd. The recommended processes were developed based on NPDES
speculative limits for RRRWWTP. A copy of National Pollutant Discharge Elimination
System (NPDES) Permit No. NCO036269 for the 24 mgd RRRWWTP dated August 18,
1997 is included in Appendix C.
The 54 mgd capacity was chosen as the ultimate build -out capacity based on flow
projections determined by Camp Dresser and McKee as provided by WSACC. The
projections included 6 mgd of flow from Charlotte -Mecklenburg Utilities (CMU) via new
interceptors now under construction as agreed upon by WSACC. Discussions between
WSACC and CMU are continuing regarding further regionalization. _ Therefore, the
ultimate build -out of RRRWWTP may exceed 54 mgd. Speculative limits have been
requested for a flow of 74 mgd. The evaluations included in this document are based on
agreements in place through December 1998 between WSACC and CMU and assume a
build -out of 54 mgd.
Average daily flows from each of the WSACC members was discussed in the
March 1998 201 Facility Plan and information is repeated as Table 2-3 for reference.

3.1 Population Projections
~ A detailed description of population projections through the year 2020 for WSACC's
system is included in Volume I of the March 1998 201 Facility Plan. The information is
still applicable, and an update is not required for the proposed facilities expansion at
L RRRWWTP. The population projects are repeated in Table 3-1 for reference.
3.2 Flow Projections
A detailed description of flow projections through the year 2020 for WSACC's
system is included in Volume I of the March 1998 20.1 Facility Plan. The discussion is
still applicable.. However, the flow projections were based on annual average flows. The
flows for RRRWWTP were modified to reflect maximum month flows. The modified
projected flows are presented in Figure 3-1.
3.3 Speculative Limits
A copy of the speculative permit limit letter dated April 24, 1996, is included as
Appendix D. These limits were requested for plant expansions to 30, 36, and 54 mgd.
The speculative permit limits are. summarized in Table 3-2. It should be noted that the
speculative limits do not change between phased expansion from 24 mgd to 54 mgd:
3.4 Phasing of Construction
Cabarrus County is predicted to experience a high growth rate over the next decade.
Therefore, the expansion of the facility is recommended to, -be staged. The 20-year
planning period flow is 44 mgd (Qd,,ip). The 1997 plant flow was 17.1 mgd (Q,). This
results in a staging period of 10 years per EPA guidelines for Qdesip/Ql, ratios greater than
1.8. (Qdesip/Q1 = 44/17.1 = 2.6.).. The 10-year design flow is predicted to be 34 mgd
(refer to Figure 3-1).
Staging ensures that oversized facilities are not constructed thereby exerting a
financial burden on the existing rate payers. .

Initial evaluations determined that the facility can be expanded to 30 mgd with
relatively little construction (HPOAS basins, gravity thickener, WAS pumps) for a 6 mgd
additional flow. Additional evaluations focused on modifications to the allotted organic
and hydraulic loads of the largest industrial wastewater discharger, Pillotex (formerly
Fieldcrest -Cannon, Inc.). The results indicated that the plant capacity could increase to
34 mgd with additional construction (second new gravity thickener with pumping station
and centrifuge) without additional expansion of the liquid train.
WSACC and Fieldcrest Cannon, Inc. (FCI) are undergoing negotiations regarding
allowable mass load and flow from the mill to the WWTP. Results of the negotations will
impact the mass and hydraulic capacities of the plant. If the current industrial flow and
strength allocations are retained, the plant is capable of treating 30 mgd (10 mgd
I�

jindustrial, 20 mgd domestic). If the allotted concentration of the industrial waste stream
is revised more in line with historical data, the plant will treat 34 mgd (10 mgd industrial,
24 mgd domestic). The design of this expansion assumes negotiations resulting in a
34 mgd plant flow. This represents a "worst case" scenario with respect to hydraulic and
{ solids loading through the WWTP.
3.4.1 Construction Phases and Design and Construction Schedules
The Process and Hydraulic Study report discusses the phasing of construction to
achieve a build -out of the facility at 54 mgd. The expansion of RRRWWTP is
recommended to occur in the following phases:
Phase 1 - Headworks (on-line mid-2000).
Phase 2 - Upgrade and Expansion to 34 mgd (on-line 2002).
Phase 3 - Expansion to 42 mgd (on-line 2007).
Phase 4 - Expansion to 54 mgd (on-line 2017).
The expansion to 42 mgd is slightly less than the 20-year planning period flow of
44 mgd. The proposed increments allows for symmetry between new liquid treatment
trains (12 mgd), allowing for ease of operation, reduction of spare parts inventory due to
like equipment, and reduction in design efforts. The upgrade and expansion projects may
require relocation of small diameter piping. However, no demolition of structures is
expected with the exception of the removal of three abandoned ash storage tanks.
Phase 1- Headworks. The headworks facility, incorporating mechanically cleaned bar
screens, vortex -type grit removal basins, and Parshall flumes, was initially a part of the
upgrade and expansion project. However, the construction schedule of the new remote
- influent pumping station required that the headworks be constructed in advance of the
plant expansion. This allowed incorporation of the flow from the new pumping station
with that from the existing.pumping station without building basins or piping that would
be abandoned. Temporary connections to existing plant piping were evaluated to be
inadequate to handle the expected flows. Therefore, the headworks facility construction
schedule was accelerated. -
The location and layout of the headworks facility required that headworks facility be
designed for the ultimate plant flow of 54 mgd annual average. Additional information
on the headworks was provided in the August 4, 1998, Engineering Amendment to the
201 Facility Plan.

Phase 2 -Upgrade and Expansion to 34 mgd. This phase will utilize the existing
capacity of the primary clarifiers, secondary clarifiers, disinfection system, oxygen
generating system, and existing process piping. Additional high purity oxygen activated
sludge basins (HPOAS) will be constructed. The facility will be converted from a series
flow mode of operation to a parallel flow mode of operation. Conversion at this level
will prevent construction of hydraulic upgrades required to increase the plant capacity in
series mode of operation. The operating mode conversion and addition of HPOAS basins
result in a relatively low construction cost per gallon plant expansion.
Phase 3 -Expansion to 42 mgd. New primary clarifier, HPOAS basins, secondary
clarifiers, additional disinfection basins, sludge thickening, and sludge pumping station
expansions will be required to expand the facility to 42 mgd. The new units will be
incorporated with the existing units. Evaluations as discussed in the Process and
Hydraulic Study Summary Report (Appendix B) indicate that the facility will be able to
meet the speculative NPDES permit limits without filters. Filters are expected to be
constructed during this expansion'phase to treat effluent for reuse purposes.
Denitrification was included in the Process and Hydraulic Study evaluations although
the NPDES speculative limits do not indicate a need to incorporate a nutrient removal
j j process. A benefit of denitrification is the partial regeneration of alkalinity and oxygen
in the treatment process. The results of evaluations indicate a substantial savings in
7 chemical costs when partial denitrification is incorporated. This would included
L) conversion of oxic cells to anoxic cells within the HPOAS basins and addition of nitrate
recycle pumping up to two times plant flow. The savings are more pronounced at.higher
plant flows. The recommendations are to incorporate the anoxic cells during the
expansion to 42 mgd, after additional HPOAS basins are constructed, to be able to
remove treatment trains from service for the conversion. The nitrate recycle pumping can
be increased to four times the plant flow for denitrification purposes if required in the
future.
Phase 4 - Expansion to 54 mgd. This phase will require additional primary clarifier,
HPOAS basins, secondary clarifiers, disinfection basins,- sludge thickening, and sludge
pumping. Additional oxygen storage capacity or oxygen generation equipment will be
required.

3.4.2 Cost -Effectiveness
The initial upgrade and expansion of the facility to 34 mgd will utilize the existing
organic and hydraulic capacities of the facility. This expansion phase is estimated to be
less than $3.50/g4llon project cost. Expansion to 42 mgd is recommended to be delayed
to allow development of reuse customers to offset the cost of filters. Evaluations indicate
that the facility will meet the speculative limits without filters with the facility operating
in parallel mode. In addition, delaying construction of the basins required for 42 mgd
will provide an increase in user base which will lessen the impact on the user fee.
Table 3-4 summarizes project costs for two scenarios. Scenario 1 includes the
recommended upgrade and expansion of the facility to 34 mgd construction beginning in
2000 , followed by expansion to 44 mgd construction beginning in 2005. Scenario 2
includes upgrade and expansion of the facility to 44 mgd construction.beginning in 2000.

Scenario 1 accounts for the present worth. of deferred costs associated with delaying
the expansion to 44 mgd. The lower construction cost of Scenario 1 favors the upgrade
and expansion to 34 mgd (begin construction 2000) followed by the expansion to 42 mgd
(begin construction 2005).
3.4.3 Facility Operation Between Phases
The existing facilities and the new facilities will .continue to be used throughout the
life of the plant. No basins or processes will be abandoned: .The. liquid treatment and
solid processes will not be converted to alternate processes. That is, activated sludge

Upgrade and Expansion

treatment and centrifugation/incineration will continue to remain in operation. The
process units will be sized for the expected organic and hydraulic loads for each phase.
- Phase 1 to Phase 2.. Addition of the headworks now allows for two primary clarifiers
to be taken off-line during the tie-in of the new. distribution box without negative impacts
on the facility. The headworks facility is sized for ultimate plant flow and, therefore, will
not need to be expanded during the plant expansions to 54 mgd. Operation of the plant
in parallel mode will allow the majority of the flow to be treated in the existing Step II
basins with Step I basins out of service for the construction of the additional HPOAS
basins.
Phase 2 to Phase 3. The new basins will be constructed separate from the existing
basins. The plant processes will be interrupted for tie-in with the existing piping systems.
Therefore, it is not expected that the major process units will be required to be out of
service for an extended period of time.
Phase 3 to Phase 4. Again, the new basins will be constructed separate from the
existing basins. The plant processes will be interrupted for tie-in with the existing piping
systems. Therefore, it is not expected that the major process units will be required to be
-' out of service for an extended period of time.

Section 4
Alternatives
4.1 General
The following discussion presents various alternatives for RRRWWTP. In addition,
planning level treatment alternative evaluations designed to meet WSACC's planned
build -out of the facility to 54 mgd are presented.
4.2 No Action
The RRRWWTP will reach 90 percent of its current rated capacity (maximum month
basis) by year 2002. If additional facilities are not constructed, the residential and
industrial growth planned for this area will not be supported. A "no action" approach will
result in permit violations, and therefore, is not an alternative.
4.3 Regional Systems
RRRWWTP is a regional system providing service to the City of Concord, City of
Kannapolis, Town of Harrisburg, Town of Mount Pleasant, and Cabarrus County.
WSACC will provide wastewater service to Mecklenburg County in accordance with an
agreement with Charlotte -Mecklenburg Utility Department (CMUD) for a portion of the
- Rocky River basin located in Mecklenburg County. Therefore, connection to an existing
i
sewerage system is not an alternative. Expansion of the regional facility will result in
fewer future treatment sites and discharge points.
A new regional wastewater treatment plant in Union County could serve a portion
of Cabarrus County, Mecklenburg County, Stanly County, and Union County. A
feasibility study has been performed for a new regional plant. If the counties decide to
implement a regional facility, the facility would not be in place in time to support the
- near future growth and projected flows for RRRWWTP. In addition, a substantial amount
of interceptors would be required to send flow to a new facility.
4.4 Land Application and Subsurface Disposal
Land application and subsurface disposal are not considered feasible alternatives for
a regional facility of this size based on the quantity of flow received at the plant, the
flows projected for the 20-year planning period, and flows projected for the ultimate
build -out of the facility. In addition, the land requirements for an application area, as
well as a 100 percent reserve area, would require a substantial amount of land purchase.

The existing land area within the property boundary is designated for future plant

4.5 New Facility
! Construction of a new facility to meet the 20-year planning period would require a
—' minimum of a 20 mgd facility. The required land area, interceptors, structures, equipment
_i and required permits do not make this an economically feasible alternative to expansion
!, j of existing facility. In addition, the impact on the environment to construct a new facility
and interceptors does not make this an environmentally feasible alternative. Also, a new
{�I facility would not be constructed and in operation in time to support the needs of the
service area.
4.6 Optimum Operation of the Existing Facility
Evaluations of the existing facility and phased expansions were performed as part of
the Process and Hydraulic Study as discussed in the Summary Report provided as
Appendix B. The following sections summarize the various scenarios presented in the
' report.
The plant was originally designed as a two -stage, series, nitrification system. The
�Jtwo -stage system provides carbonaceous BOD removal in Step I high purity oxygen
activated sludge (HPOAS) basins and clarifiers followed by nitrification (TKN removal)
in Step II HPOAS basins and clarifiers.
Existing diversion boxes and interconnecting piping allow parallel flow. This flow
F, arrangement allows for a single -stage, parallel, nitrification system. To accomplish this,
I`! primary clarifier effluent can be split between Step I and Step II basins. In this now
__ scheme, carbonaceous and nitrogenous oxygen demand are satisfied in a single basin.
L
This alternative considers a paper re -rating of the facility with minor modifications
to the facility. The modifications would include increased WAS pumping capacity and
Jgravity thickener No. 3 to allow separate thickening of primary and waste activated
sludges to reduce odors. Neither aeration basins, primary, nor secondary clarifiers would
be constructed. Activated sludge process modeling of the existing RRRWWTP capacity
-- was performed for both parallel (single -stage) and series (two -stage) operation.
Series Mode. Modeling of Step I system for carbonaceous BODS removal followed by
Step II for nitrification resulted in a capacity of 26.5 mgd. The solids loading rate to the
Step I and Step II clarifiers was the limiting factor in determining this capacity. Stress
Black & Veatch 4-2 WSACC—Rocky River Regional WWTP
February 3, 1999 Upgrade and Expansion

IJ testing of the clarifiers verified the limiting capacity of the liquid treatment processes to
26.5 mgd in series mode.
Parallel Mode. Modeling of the Step I and Step II HPOAS basins and clarifiers
operating in parallel resulted in a total capacity re -rating of 25.5 mgd. Step I and Step II
j I would have a capacity of 8.5 and 17 mgd, respectively. Hydraulic retention time in the
HPOAS basins at winter maximum month loading was a limiting factor. Additional
aeration basins would be required to achieve more treatment in parallel flow (single -
stage).
A re -rating of the facility would add capacity to the facility; however, the 1.5 to
2 mgd increase would not be sufficient to meet the needs of the service area. Therefore,
re -rating alone is not a feasible long-term option.
4.7 Upgrade Existing Facility
Operational and minimum plant modifications required to upgrade the plant treatment
capacity from 24 mgd to 27 mgd were determined as part of the -Process and Hydraulic
Study. This alternative includes construction of basins, excluding HPOAS basins.
Series Mode. In order for the plant to be upgraded to 27 mgd operating in series mode,
the following improvements would be required:
• Increase WAS firm pumping capacity.
• Add gravity. thickener (GT-3).
• Add alkalinity supplementation.
• Implement Step II hydraulic upgrade.
• Add final clarifier.
The hydraulic upgrades would include (1) modification, of distribution box,
(2) replace or parallel undersized piping, and (3) expansion of Step II (RAS and process
- flow) pumping station.
Parallel Mode. In order for the plant to be upgraded to 27 mgd operating in parallel
mode, the following improvements would be required:
• Increase WAS firm pumping capacity.
• Add gravity thickener (GT-3).
• Add alkalinity supplementation.
• Add final clarifier.
Black & Veatch 4-3 WSACC—Rocky River Regional WWTP
February 3, 1999 Upgrade and Expansion
1

The cost of constructing the hydraulic upgrades favors the conversion to parallel
mode of operation. However, the 3 mgd increase would not be sufficient to meet the
needs of the service area in the near future. Therefore, upgrades alone is not a feasible
Li long- or short-term alternative.
4.8 Upgrade and Expand the Facility-10-Year Requirements
Operational and plant modifications required to increase the plant treatment capacity
from 24 mgd to 34 mgd were determined. Evaluations were based on successful
negotiations between WSACC and Pillowtex regarding allotted mass and hydraulic loads.
Series Mode. In order for the plant to be upgraded and expanded to 34 mgd operating
in series mode, the following improvements would be required:
• Increase WAS firm pumping capacity.
Add gravity thickeners (GT-3, GT-4).
Li 0 Add thickened sludge pumping station.
Add third centrifuge.
j0 Add alkalinity supplementation.
J
• Implement Step II hydraulic upgrades.
Add final clarifier.
• Add piping, distribution boxes, and manholes.
The hydraulic upgrades would include the same items identified in Section 4.7 above.
Parallel Mode. In order for the plant to be upgraded and expanded to 34 mgd operating
in parallel mode, the following improvements would be required:
• Increase WAS firm pumping capacity.
Add gravity thickeners (GT-3, GT-4).
• Add thickened sludge pumping station.
• Add third centrifuge.
• Add alkalinity supplementation.
• Double Step I HPOAS basin volume.
Add piping, distribution boxes, and manholes.
Basically the difference between the modes of operation is the addition of a final
clarifier and hydraulic upgrades versus doubling Step I HPOAS basins. However,
consideration should be given to construction that would be abandoned in the future,
i.e., the hydraulic upgrades.

4.9 Upgrade and Expand the Facility —Build -out Requirements
The existing property includes sufficient useable land for expansion purposes to
54 mgd. The alternative analyses were based on the build -out of the facility to 54 mgd
and not the 20-year requirements. The objective was to determine the unit processses
required for the planned ultimate plant capacity from which intermediate expansions
would be developed. This prevents design of structures and processes during intermediate
expansions that would be abandoned in future expansions.
4.9.1 Wastewater Treatment Aitematives .
The evaluated alternatives include the following:
Alternative 1. Expand existing facility to 30 mgd (series mode), add new 24 mgd,
two-step HPOAS train (series mode): Existing facility and new facility would operate
independent of each other.
Alternative 2. Expand existing facility to 54 mgd (parallel mode). Facility would
operate as one plant.
The process requirements for the alternatives are summarized in Table 4-1. The
design operating conditions are listed in Table 29 of the Process and Hydraulic Study

The present -worth cost evaluation of the two options is included in Section 5. The
evaluation considered only those structures, piping and equipment that differed between
the two options. The cost difference between the two alternatives was determined to be
$12.6 M in favor of Alternative 2—expand the existing facility to 54 mgd and operate in
parallel mode.
Altemative 3. Expand existing facility to 30 mgd and add new 24 mgd conventional
activated sludge train. Existing facility and new facility would operate independent of
each other. This alternative was given cursory evaluation only, based on the results of
L' a comparison of Alternative 1 to Alternative 2. The present -worth costs of Alternative 3
would be greater than the present -worth costs of Alternative 1 for the following reasons.
The footprint of a conventional activated sludge basin would be similar to that of the
HPOAS basins. HPOAS basin footprint is typically smaller than that for conventional
activated sludge basins due to the high oxygen transfer within the covered HPOAS basins.
Increasing the depth of the basin for the required conventional activated sludge system
will result in approximately the same footprint as that of the HPOAS basin. Therefore,
the structural costs associated with a conventional basin would be similar to that of
Alternative 1. However, the equipment costs would be greater due to the addition of a
blower system. The blowers would also add to the annual power costs. The oxygen
generation equipment associated with the HPOAS does not require expansion to achieve
54 mgd-only storage tanks are required or oxygen purchased during peak day periods.
The net result is that Alternative 3 would have a greater present -worth cost than
_ Alternative 1. Therefore, Alternative 2 would remain the recommended alternative.
4.9.2 Solids Thickening Altematives
The solids processing alternatives for a 54 mgd facility were developed based on a
liquid treatment process consisting of primary treatment and parallel operation of HPOAS
basins and secondary clarifiers. The projected sludge quantities are listed in Table 45 of
the Process and Hydraulic Study Summary Report in Appendix B.
Altemative 1. This alternative assumes the facility is expanded and operated similar to
the existing facility with respect to solids handling. Primary sludge and waste activated
sludge will be thickened in gravity thickeners. The sludges can be co -thickened or
separately thickened. A total of six gravity thickening units and a new thickened sludge
pumping station will be required.
- Black & Veatch 4-7 WSACC—Rocky River Regional WWTP
February 3, 1999 Upgrade and Expansion

1
The advantages of gravity thickening is that the existing gravity thickeners are
utilized and are compatible with the existing centrifuges and incinerator. Also, operation
and maintenance costs are minimal, requiring very little attention. In addition, gravity
thickeners offer sludge storage capacity.
Altemative 2. This alternative assumes the existing gravity thickeners will handle the
primary sludge. Gravity belt thickener (GBT) units will be added to thicken WAS only.
_- The existing WAS pumps would be used to transfer WAS from the clarifiers to the GBTs.
The GBTs would process 1-day WAS production in two 8-hour shifts. No backup units
are included. The GBTs could be operated an additional shift in the event that one unit
is out of service. New thickened sludge pumps would be required to transfer the
thickened sludge from the GBTs to the thickened WAS (TWAS) storage tank. This
;i
allows storage of TWAS for continuous feed to the dewatering/incineration process
without 24-hour operation of the GBTs. TWAS transfer pumps would be required to
_ transfer TWAS from the holding tank to a blending tank. The existing centrifuge feed
pumps would be used to deliver the primary sludge to the blending tank. A blending tank
with mixer for mixing thickened WAS with the gravity thickened primary sludge for
dewatering and incineration or disposal will be required. New transfer pumps would be
j required to deliver the blended sludge to the centrifuges. A total of four 3-meter gravity
belt thickener units will be required. The GBTs would require a polymer system and a
building to house the equipment. The operation and location of the units would be such
that an operator would be in attendance during unit operations. The building may require
ventilation during operation of the units.
Advantages of GBTs are that they provide efficient WAS thickening, occupy less site
area, and will allow using the existing gravity thickeners and centrifuges. The
disadvantages are the additional operation (labor and .polymer.) and maintenance costs.
The present -worth cost evaluation of the two options is included in Section 5. The
evaluation considered only those structures, piping, and equipment that differed between
the two options. The results do not favor one alternative over the other. However, as
discussed in Section 5, gravity thickeners is the recommended alternative. The cost
analysis for the plant expansions includes incorporation of gravity thickeners based on this
recommendation.

4.10 Proposed Upgrade and Expansion Project
The civil design memorandum for the proposed upgrade and expansion of the
RRRWWTP is provided in Appendix F. This document includes design criteria for the
unit processes. A cost opinion of the proposed design will be provided in a supplement
to this amendment. It should be noted this facility was constructed 20 years ago.
- Therefore, several components have reached their useful life and require replacement or
upgrade. Justification for the individual upgrade and expansion items not previously
discussed in this plan are as follows. Further details of components can be found in the
design memoranda included in Appendix F.
4.10.1 AFDs and MPS Ventilation
The two largest pumps (600 hp) are constant speed pumps and are activated
- manually based upon wetwell level. Adjustable frequency drives (AFDs) will be added
to these pumps. Also, control logic will allow for automatic control and activation of the
pumps. This will. allow the pumps to ramp up to speed during rising wetwell levels to
i
stabilize the level resulting in gradual flow increases rather than slugging the plant when
a constant speed pump starts. Also, influent pumping will mirror actual flow in the
interceptors to prevent using the interceptors for equalization. Finally, allowing the
pumps to ramp up in speed will reduce power requirements which translates into lower
operational costs. The power billing demand at the facility is set based on the highest
peak demand at any given time. The billing demand is applicable for a 12-month period
beginning at time of the peak demand. Historically, this has occurred during a storm
event in which both of the largest influent pumps are operated to lower the wetwell level.
The AFDs will prevent high wetwell level situations, thereby reducing the peak demand
and the associated monthly charge.
The ventilation improvements are necessary to dissipate the heat generated by the
equipment and make the environment suitable for the AFDs. The improvements include
addition of louvers and power roof ventilators.
4.10.2 Thickened Sludge Pump No. 2
The existing thickened sludge pumping station contains two pumps, one for each
existing gravity thickener. Initial operation of the gravity thickeners combined both
primary sludge and waste activated sludge in each gravity thickener requiring only one
pump pulling sludge from one gravity thickener to feed a centrifuge. Current operation
of the thickeners provides separate thickening of the sludges to reduce odors and
corrosion. The sludges are blended in -line to the centrifuges. Therefore, two pumps in
Black & Veatch 4-9 WSACC—Rocky River Regional WWTP
February 3, 1999 Upgrade and Expansion

operation with a standby pump capable of drawing from either gravity thickener are
required. Space is available within the pumping station for the third pump.
4.10.3 WAS Metering
Original design did not provide WAS metering capability for the Step II process.
Conversion of the facility to parallel operation creates a need to measure WAS from the
Step II side of the facility.
4.10.4 Odor Control
1'
Hydrogen sulfide levels in the area of the existing gravity thickeners have been
measured in the 20 ppm range. To comply with current and future air pollution
guidelines, a method for capturing and treating theses odors is needed. This will partially
be addressed by . rerouting the centrate and thickener drains as indicated under
Section 4.10.8. The existing and proposed gravity thickeners will be covered and the
off -gases scrubbed. The odor control system will treat exhaust air from the gravity
thickeners and centrifuges. The system will consist of a packaged multistage scrubber,
recirculation pump, sodium hydroxide feed pumps, and sodium hypochlorite feed pumps.
The gravity thickeners will be fitted with flat covers to minimize the volume of air to be
treated. The spent sodium hydroxide will be discharged to aeration treatment process as
iJ
part of the alkalinity supplementation process. This minimizes the different types of
chemicals required onsite,'combines storage and feed facilities, and reduces disposal cost
for the spent scrubber chemical.
4.10.5 Oxygen Plant Controls
The existing cryogenic oxygen generation plant is presently monitored and controlled
from a local control panel at the oxygen plant. A majority of the controls are pneumatic
- and are nearing the end of their useful life. The oxygen plant instrumentation and control
system will be replaced with -a new PLC -based system that will allow remote monitoring
and control through the plant control system.
4.10.6 Liquid Sludge Truck Unloading Station
The existing truck unloading station is a dedicated manhole in the plant drain system
with plant water available for wash down. Septage is discharged into the manhole where
it enters the liquid process flow stream at the main pumping station. Liquid sludge can
i
be discharged at the septage receiving manhole, however, this would require pumping the
sludge to solids separation process that can create high loadings on the pumping and
YJ Black & Veatch 4-10 WSACC—Rocky River Regional WWTP
February 3, 1999 Upgrade and Expansion

primary process units. A liquid sludge truck unloading station is proposed to provide the
capability for septage haulers to discharge directly to the gravity thickeners. In addition,
the facility will be able to accept liquid sludge from other treatment facilities as a
� 1
supplement to ongoing land application programs in the area when access to fields is
( ) limited.
—� The estimated construction cost of the liquid sludge unloading station is $20,000.
The fee for septage is 2.5 cents/gallon. Currently, three to four trucks per day at
2,000 gallons per truck discharge septage at facility. The payback period for the new
station is less than 1 year.
($20,000 Capital)/(3 trucks/day)(2000 gal/truck)(2.5¢/gallon)(1$/100¢) = 133 days
4.10.7 Miscellaneous Improvements
Primary Clarifier Weir Modification. The existing primary clarifiers are center feed,
peripheral effluent with serpentine weirs. The configuration of the weirs makes cleaning
of the weirs manually or mechanically difficult. The fingers of the weirs will be removed
and the remaining portion of the weirs converted to peripheral circular weirs. Brushes
can be added to the scum skimmer arm to automatically clean the weirs, thereby reducing
the associated maintenance labor.
HPOAS Basin Scum Removal. Currently, scum must be manually skimmed from the
effluent channel of the. HPOAS basins. A telescoping valve and drain pipe with an
isolation valve will be added. to each effluent channel in existing HPOAS basins. The
'~ scum., will flow to the plant drain.
Scum Wetwell Modification. Scum is no longer pumped to the solids handling
processes due to the excess amount of water required to flush the scum to the scum
wetwell. The scum is directed to the main pumping station where a portion is removed
by the barscreens. A drain pipe will be added to the scum well to allow draining of the
excess water, thereby concentrating the scum before pumping to the solids handling
facility. Discontinuation of sending the scum back through the liquid treatment process
through the main pumping station will have a positive impact on the processes, one of
which is an expected decrease in filamentous growth in the clarifiers. The existing pumps
and transfer piping will not be modified.
Black & Veatch 4-11 WSACC—Rocky River Regional WWTP
February 3, 1999 Upgrade and Expansion

Effluent Sampling Pad. A sampling station at Box 6 samples wastewater following
Step I treatment and prior to Step II treatment. A sampling station at the microscreens
bypass channel samples the combined effluent prior to discharge. A separate sampling
station for effluent from Step II was not provided in the original design. The conversion
of the facility to parallel mode of operation requires a sampling station to monitor and
— control existing Step II processes. The sampling pad will be located at Manhole No. 47.
The sampler will be provided by the owner.
Electric Actuators. Electric actuators will be added to the existing return activated
sludge control butterfly valves• located at the eight metering flumes. Currently, these
valves are adjusted twice a day to control the RAS flow. The actuators will allow the
operators to automatically adjust the valves through the plant control system (PCS) to
match the RAS with the plant influent, flow thereby improving the process.
Electric actuators will be added to the two chlorine contact basin isolation sluice
gates. These gates are very difficult and strenuous to operate. The actuators will save
operator time and risk of injury.
4.10.8 Reroute Drains
The centrate, conditioner/scrubber discharge and gravity thickener overflow combine
in the plant drain which flows to the main pumping station. Hydrogen sulfide levels
measured at the plant drain manholes outside the Dewatering Building were measured in
the 400 to 600 ppm range. The elevation drops between manholes in the plant drain
system allows for stripping of volatile components leading to odor problems. In addition,
the drain flow is repumped to the head of the plant (originally to the primary clarifier
splitter box, ultimately to the new headworks).
Currently, the centrate, conditioner/scrubber and gravity thickener overflow accounts
for more than 2 mgd of flow. This equates to approximately $12,000/year in power cost
to repump the flow. Rerouting the drain will reduce the odors generated onsite, reduce
the cost of odor control that may be required in the future, and reduce pumping costs.
4.10.9 Plant Control System
The Plant Control System Master Plan for the Rocky River Regional WWTP is
included in Appendix B. The plan recommended a plant control system that is PC/PLC
based as the best approach for this facility. This technology is widely accepted in the
wastewater treatment industry and will bring this facility up-to-date with current
technology, reducing manpower required for monitoring and control of the system.

4.10.10 Alkalinity Feed Improvements
Original plant design incorporated lime slurry feed for the purposes of conditioning
sludge for the pressure filter presses. The lime system was maintenance intensive. The
- replacement of the filter presses with centrifuges deleted the need for the system. The
lime towers will be demolished for the construction of the headworks facility. Therefore,
facilities to be converted for alkalinity supplementation are not available. Alkalinity
supplementation is required to maintain appropriate pH for proper process control. The
alkalinity feed system will be combined with the odor control system to reduce storage
requirements. A sodium hydroxide system will be installed to supply supplemental
alkalinity to the biological treatment system. The chemical storage and feed facilities will
be located in the Odor Control/Alkalinity Feed Building. The alkalinity feed system will
also be used in the odor control chemical scrubbing system
4.10.11 Secondary Clarifier Rehabilitation
The secondary clarifiers are peripheral feed, peripheral effluent clarifiers with
serpentine. weirs. The weirs are difficult to clean and will be modified similar to the
primary clarifiers. Additional items of the secondary clarifiers require rehabilitation due
Y to wear and corrosion over the last 20 years. These items include the following.
replace orifice baffles, anchor bolts, washers, and nuts.
• re -anchor scum baffle.
• reweld center column to base plate.
replace suction header and guide wires.
• replace bearing races, ball bearings, upper and lower seals, and dust seals.
• increase strength of metal in area where support for the skimmer is attached to
the scraper truss arm.
• replace turnbuckle.
The clarifiers were inspected by WSACC to determine which components were
required for each unit. Only the required items will be incorporated for each clarifier.
In addition, badly chipped grout may be removed and replaced as required during the
rehabilitation. The rehabilitation for all eight clarifiers is estimated to be $200,000 capital
i cost. In comparison, the total replacement of the mechanics is estimated to be $195,000
for each clarifier.
4.10.12 HPOAS Mixers, Step 1 Replacement
Operation of the facility in parallel mode requires less mixing horsepower. A present
worth cost evaluation was performed to determine the feasibility of delaying the Step I
Black & Veatch 4-13 WSACC—Rocky River Regional WWTP
February 3, 1999 Upgrade and Expansion

�f
HPOAS mixer replacement. The present worth cost of operating the existing mixers
(power cost of 3 @ 150 hp, 3 @ 75 hp and 3 @ 60 hp) would be $3,163,000 over a
i 20-year period at 7.375 percent interest. This value assumes the existing mixers will not
- J be replaced within the 20 years. The present worth cost of the replacement -mixers
(capital and power) for nine-30 hp mixers is $1,465,000. The savings in power cost due
to mixer replacement results in an approximate payback period of 2 years. Therefore, it
is recommended that the mixers be replaced ' during this expansion.
4.10.13 Standby Power
The power to the facility is fed through parallel lines from the same transfer station,
one line serving as a back-up for the other. However, if the transfer station is not
" t functional, all power to the facility is lost as demonstrated in the past. The proposed
design will incorporate a standby power system to feed critical facilities in accordance
with current regulations. This will include all liquid process facilities.
4.10.14 Thickened Sludge Pumping Station No. 2, TSPS-2
The location of the new gravity thickeners and distribution box and the lack of
available room in the existing pumping station require a new thickened sludge pumping
station. be constructed. The new station will be sized to house thickened sludge pumps
for the two proposed gravity thickeners and two additional future gravity thickeners.
4.10.15 WAS Pumps
The WAS firm pumping capacity needs to be increased to adequately serve the
expanded facility. The existing pumps will be removed and salvaged then replaced with
larger units.
4.10.16 Centrifuge
The third centrifuge is required for firm capacity to meet reliability criteria in the
event maintenance is required. WSACC has experienced problems in the past due to
maintenance of the existing units.
4.10.17 Administration Building Extension
A women's locker room and an extension to the laboratory will be added. The
- number of women on staff has resulted in a need to provide a women's locker facility.
The existing laboratory area available for testing is approximately 1,200 square feet
and is not large enough to accommodate the testing required at this regional facility. An
Black & Veatch 4-14 WSACC—Rocky River Regional WWTP
February 3, 1999 Upgrade and Expansion

� t
additional 570 square feet of laboratory, space will be added. This is reasonable for a
30 mgd regional facility that will be expanded to ultimately 54 mgd.
4.10.17 Unspecified Improvements
Sludge Cake Receiving Station. WSACC is considering including a sludge cake
receiving station to be used by area utilities as an alternative to sludge disposal at a
landfill. The facility would include: a 42-cubic yard steel storage bunker, hydraulically
actuated sliding frame bottom, and double loading doors; 30-35 gpm hydraulically -driven
piston pump; power pack; and PLC -equipped control panel. Additional cost for the
receiving station is $750,000 assuming the bunker and sludge pump needed beneath
centrifuge No. 3 is relocated in the cake receiving station and dewatered sludge is
conveyed to this bunker from Centrifuge 3 via enclosed screw conveyors. Total capital
recovery is estimated to be $120/dt which is competitive with the landfill tipping fee of
$177/dt.
4.11 Open Space and Recreational Opportunities
Construction of the facility expansion will not affect land outside of the existing
property boundary. The expansion will not be adding or removing open areas for
recreational opportunities. The discharge to the river will not diminish any canoeing
activities of the river.

Present -Worth Analysis
5.1 General
The present -worth cost analysis for the selected alternatives includes a 20-year
evaluation period with a 7.375 percent factor. The analyses include the following:
^(0 Capital costs.
• Present -worth of engineering costs.
• Annual maintenance costs and annual power costs.
J Present -worth of maintenance and power costs.
• Salvage value of equipment.
• Present -worth of salvage value.
_J
• Present -worth of replacement costs.
The present -worth evaluations discussed in this section include the following:
Series versus parallel mode of operation for wastewater treatment.
• Gravity belt thickeners versus gravity thickeners for sludge dewatering.
�J It should be noted that no land purchase is required for this plant expansion.
5.2 Wastewater Treatment Alternatives
As discussed in Section 4, the treatment alternatives for the planned ultimate
build -out include the following: .
Altemative 1. Expand the existing HPOAS facility to 30 mgd and add a new 24 mgd
-' HPOAS facility for a total plant capacity of 54 mgd. The facility would operate in series
mode.
Altemative 2. Expand the existing HPOAS facility to 54 mgd. The facility would
operate in parallel mode.

Based on the above analysis, conversion to parallel mode of operation for expansion
to 54 mgd is clearly the recommended alternative.
5.3 Solids Handling Alternatives
The solids handling alternatives for plant ultimate build -out include the following:
A►temative 1. Add gravity thickeners and thickened sludge pumping for WAS.
Altemative 2. Add gravity belt thickeners, thickened sludge holding, and thickened
sludge pumping for WAS and sludge blending tank for WAS and primary sludge.

The results are not definitive with respect to present -worth costs. The recommended
choice was gravity thickeners for the following reasons:
i
• Low maintenance requirements.
Low operator attention requirements.
• Owner familiarity with equipment.
Proven treatment reliability at this facility.
• Basins offer a wide spot in the system should multiple dewatering equipment
be out of service.
The evaluation did not include a WAS holding tank other than the existing WAS
pumping station wetwell. If multiple equipment were down for extended periods of time
with Alternative 2, the amount of wasting would have to be reduced. This may have an
adverse impact on the activated sludge treatment process.

Section 6
User Charges and Financial Capability
6.1 General
i This section updates the financing of some of the projects as'presented in the March
1998 201 Facility Plan and August and September 1998 Supplements. The debt service
^! estimates include both SRF loan -financed projects and bond -financed projects. The
-' source of bond funds may be from the recent water/sewer referendum or from revenue
bonds. The impact of the increased debt service on the customer rates is estimated.
_ The user charges and finance capabilities evaluated in the March 1998 201 Facility
Plan included $6M funded by revenue bonds for the wastewater treatment plant upgrade
to 27 mgd. The plant upgrade project has been delayed and combined with the expansion
to 34 mgd project. The headworks facility, originally included as part of the upgrade to
+� 27 mgd project, could not be delayed in order to support the operation of the new
interceptor and pumping station expected to be on-line mid-2000. The engineering
j amendment submitted August 1998 addressed the headworks facility as a revenue bond
i_ item. Currently, an SRF loan is being sought to finance the headworks facility project.
-� It is understood that SRF loan funding may not be available for the plant expansion
project. However, Bill Bonds will be available up to the entire project cost. Therefore,
the debt service estimate included in the March 1998 Plan and following supplements is
updated as follows:
• Delete $6M for plant upgrade to 27 mgd from the list of revenue bond financed
projects.
• Add $3.5M for headworks facility to the list of SRF loan financed projects.
-- Add $20.5M for plant expansion to the list of bond -financed projects.
The plant expansion cost opinion is a preliminary cost estimate and should not be
considered as a final design cost opinion.
i
6.2 Annual Cost of Projects
The SRF loan projects include a 2 percent closing cost assessed by the state for
administrative costs. The debt service calculation is based on 20-year level principal and
it
4 percent interest charge on the declining balance. The revenue bond projects . assume
capitalized interest for 2 years, 2.6 percent issuance costs, 2.5 percent debt service reserve
insurance, and 6 percent interest. The bill bond projects assume capitalized interest for
2 years and 5. percent interest.
I
Black & Veatch 6-1 WSACC—Rocky River Regional WWTP
February 3, 1999 Upgrade and Expansion

The debt service payment will be greatest in the first year of debt and will gradually
decline over time. Therefore, the impact on rate payer will be greatest in the first year.
�I Table 6-1 summarizes the project costs, fiscal year 2001 annual costs, and impact on
residential costs for all currently identified SRF loan, revenue bond, and bill bond
�l financed projects. Table 6-2 demonstrates a substantial savings through SRF loan
-! program versus bill bond financing.
The updated project cost increased the estimated annual impact on residential
I customers to $0.64/1,000 gallons.
LJ
6.3 User Charges
WSACC does not serve nor bill residential customers directly. WSACC includes the
debt service in the fixed portion of the billing to the wholesale customers. Therefore, it
is assumed that each wholesale customer who serves residential customers passes the cost
�— to the customer. This is consistent with the methodology used in the March 1998.Facility
Plan.
Table 6-3 summarizes the changes in fixed and variable costs to the wholesale
customers and the impact on the residential customers on a 5,000 gallon per month basis.
The interceptor fixed costs were updated to. reflect the current project cost estimates. The
FY2001 treatment variable costs were updated to include energy and O&M costs
-J associated with the new headworks and pumping station.
6.4 Finance Capability
Table 6-4 is the financial forecast revised to include the updated headworks and plant
expansion project costs. The data show debt service coverage and positive net income.
