1.0 INTRODUCTION
The Town of Pembroke (Town) owns and operates a 1.33-MGD Wastewater Treatment Plant (WWTP)
which provides wastewater treatment for the Town's customers. Exhibits 1 and 2 show, respectively, the
vicinity of the WWTP within the Town and a close-up of the WWTP and its individual components.
The WWTP operates under NPDES permit NC0027103 as a "major" facility (more than 1.0-MGD as
classified by the USEPA). The treatment of wastewater effluent is accomplished through secondary
treatment using parallel oxidation ditches and solids sedimentation. The treatment train includes an influent
pump station, manual and mechanical barscreen, grit removal system, oxidation ditches, clarifiers,
chlorination, and dechlorination. Management of the plant is accomplished by Town employees. Sludge
solids produced in the WWTP are aerobically digested and then hauled as a liquid for composting. Off -site
composing is performed by licensed contractors through a disposal contract arrangement. Exhibit 3 is a
schematic of the current hydraulic profile.
Wastewater treatment was begun in Pembroke during the Works Progress Administration circa 1935. The
original plant site was located near the back of the existing property. The last significant improvement of
the Town's plant occurred in 1995 when the current plant was built.
The purpose of this document is to evaluate technologically feasible alternatives to expand the treatment
capacity and discharge capacity of the Pembroke WWTP from 1.33-MGD to 2.0-MGD. At the time of this
evaluation, the NPDES Unit has reviewed and provide the Town with speculative limits for an expansion to
2.0-MGD at the existing discharge location. See Appendix A for this letter and recent correspondence with
the NPDES Unit which states the letter is still valid. Additionally, this project is being funded by the US
Department of Commerce, Economic Development Administration (EDA). Pursuant to the National
Environmental Policy Act (NEPA), EDA has completed their assessment of the potential of the proposed
project to affect the environment and/or historic properties. This project was documented for NEPA
purposes with a Categorical Exclusion. Appendix A contains the official Public Notice and Affidavit of
Publication.
The proposed WWTP expansion project components and a preliminary layout can be found in Exhibit 4.

2.0 ESTIMATED WASTEWATER TREATMENT PLANT FLOWS
The Town of Pembroke wastewater flow characteristics include residential, commercial, institutional, and
industrial components. The methodology for determining reasonable projection for population and flow can
be found herein. Due to limited 2021 data, the assumptions for flow projections are based on 2020 user
information and metered flows. Appendix B provides supporting data and information for the projections
described in this section.
2.1 POPULATION PROJECTIONS
The Town of Pembroke is requesting a NPDES discharge permit for expanding their wastewater discharge
from 1.33-MGD to 2.0-MGD. The following population projections are based on the historical data obtained
from the NC Office of State Budget and Management (available historical data through 2019) and
forecasted linearly based on the prior 10-year data. The data provided does not include the enrollment
population at the University of North Carolina at Pembroke. The requested permit increase is intended to
satisfy a 20-year planning horizon from the time of permit issuance (i.e., 2021-2041).

2.2 FLOW PROJECTIONS
The following sub -sections include justification of flow projections as well as the demonstration of need for
expansion of the current permitted flow.
2.2.1 CURRENT FLOW AND SUMMARY OF USERS
The following table is a summary of water usage flows for the year 2020 as published in the Town's Local
Water Supply Plan, these flows will be basis for determination of the inflow and infiltration impacts on the
system.

Note — Institutional flows listed in the LWSP are included as part of the commercial flow for the purposes of forecasting projections
Furthermore, the Town has two (2) significant users that make up a portion of the above listed industrial
flows and meters. These users are the University of North Carolina at Pembroke, and the Town's only
significant industrial user, Steven Roberts Original Desserts. For the purposes of projecting the flows for
these users the following information and methodology will be used:
• University of North Carolina at Pembroke
According to the University's 2019 Campus profile, fall 2019 enrollment was 7,698 students
with 3,300 students living on campus. The rest are living at home and/or commuting from
outside the area. A 2011 UNC-Pembroke technical memorandum for water and sewer
infrastructure indicated a projected sewer flow of approximately 100,000 gallons per day
at the time. For the 6,900 students enrolled at the time, the average wastewater flow per
student would be approximately 14-gpd per student. At this same rate, the additional 798
students enrolled since 2011 would result in approximately 108,000-gpd. Monthly water
billing data for UNC-Pembroke (2013 to 2019) versus student enrollment indicates a
demand (on a per student basis) of approximately 14-gpd per student is indeed
appropriate.
The University website has enrollment trends from 2000 to 2018. This data indicates an
average total enrollment increase of 3,692 students from 3,445 in 2000 to 7,137 in 2018.
This is equivalent to an increase of 205 students per year. A jump of 561 students occurred
between 2018 and 2019 due to tuition reductions through the NC Promise program. Using
the historical trend rate of 205 additional students per year, the current 2021 student

enrollment would be 8,108. The 2041 student enrollment would be increased by an
estimated 4,510 students since 2019. This would add approximately 63,000-gpd of
additional wastewater flow from UNC-Pembroke (at 14-gpd per student). The table below
summarizes the above methodology for the current (2021) and the 20-year (2041) flows.

• Steven Roberts Originals Desserts (SR Originals)
o SR Originals is the Town's only Significant Industrial User (SIU). The industry's current
industrial user permit (IUP) allows for a maximum daily flow of 40,000 gallons. According
to the SIU's metering data, SR Originals current (2020) average monthly flow is 32,000-
gpd, with a range of 24,000 to 43,000-gpd. At this time, there is no plans for an expansion
of flow beyond the IUP permitted limit at the facility, and to reasonable project the future
flows for this user, the IUP's maximum allowable daily flow will be held constant for 20-year
projections (i.e., 40,000-gpd).
The following table indicates the maximum month wastewater flow over the last 48 months at the WWTP
as reported in daily monitoring reports. A copy of the DMR can be found in Appendix B.

2.2.2 FUTURE FLOW
Per the EAA Guidance Document — October 2019, flow projections represent the average anticipated flows,
and are determined based on the maximum month flow over the past 4-years. Flow projections were
estimated using the formula provided in the Guidance for the Preparation of Engineering Reports and
Environmental Information Documents for Wastewater Treatment Plant Projects — May 2015.

3.0 ENGEERING ALTERNATIVE ANALYSIS
As required by the NPDES Permit Unit, the following alternatives are evaluated to provide the most cost-
effective solution for disposal of the wastewater generated from the Town of Pembroke's service area.
Appendix C contains supporting information for the alternatives detailed herein.
3.1 ALTERNATIVE 1: CONNECTION TO CITY OF LUMBERTON COLLECTION SYSTEM
This alternative considers disposal of the wastewater generated in the Town of Pembroke's service area to
the closest existing wastewater treatment system - the City of Lumberton sewer system. Due to permitting
and alignment issues with conveying the flow along Interstate-95, the route evaluated was along state-
owned roads and existing rights -of -way. The evaluated alignment is approximate 15-miles. Due to the
length of the system and high pressure to convey the wastewater, an intermediate pump station is required
to keep the pumping head in a reasonable range. This alternative would result in the shut down of the
existing treatment systems at the VWVfP. The detailed description and cost analysis of this alternative are
provided as follows:
3.1.1 DESCRIPTION
The principal components for this alternative are described as follows:
1. Provide new duplex 3,500-gpm capacity influent pump station, associated appurtenances, and
37,700-LF of 16-inch forcemain to new intermediate pump station.
2. Provide new duplex 3,500-gpm capacity intermediate pump station, associated appurtenances,
and 38,100-LF of 16-inch forcemain to Lumberton VVVVfP headworks.

3.2 ALTERNATIVE 2: LAND APPLICATION
This alternative considers disposal of the 100% of the treated wastewater effluent from the WWTP by land
application. The pertinent information on evaluation of this land application alternative, description, and cost
analysis of this alternative are provided in the following sections.
3.2.1 LAND APPLICATION SITE WITH SUITABLE SOILS
Disposal of the treated wastewater effluent by land application requires adequate land with suitable soils
that allow for infiltration of the applied wastewater to meet the irrigation needs of the cover crops and
recharge of groundwater. In the vicinity of the WWTP site, approximately 465 acres of both cleared and
forested land with suitable soils is available for disposal of decanted wastewater by land application using
a spray irrigation system. This site includes soil types such as Dunbar sandy loam (Dn), Duplin sandy loam
(DpA), Goldsboro loamy sand (GoA), Lynchburg sandy loam (Ly), Marlboro sandy loam (MaA), Norfolk
loamy sand (NoA and NoB), and Walgram loamy sand (WaB). These soils are suitable because the majority
of the classes are moderately well to well drained and contain high water table depths in the range of 2.0
to greater than 6.0 feet below the ground levels. A brief description of these soil types are given in the Soil
Survey of Robeson County, North Carolina, provided as follows:
Dunbar sandy loam, 0 to 2 percent slopes (Dn): This nearly level, somewhat poorly drained soil is
on broad flats, in bays, or in depressions on uplands. Most mapped areas cover 4 to 72 acres. Included
with this soil in mapping are small areas of soils that have a surface layer of fine sandy loam or loam.
Also included are small areas of Coville, Duplin, Lynchburg, Rains, and Trebloc soils and some small
areas of soils that have a subsoil of sandy clay that extends to a depth of less than 60-inches. This soil
is suited to most locally grown crops. The main crops are corn, soybeans, cotton, tobacco, small grain,
and truck crops, such as snap beans, tomatoes, cucumbers, sweet potatoes, and onions. Drainage
may be required for some crops, such as tobacco. This soil has good tilth and can be worked within a
fairly wide range of moisture content. Tillage operations, however, are delayed in wet season. Winter
cover crops, minimum tillage, and crop residue management help to maintain tilth and the organic -
matter content. Moderately slow permeability and a seasonal high water table are the main limitation in
the use and management of this soil.
Duplin sandy loam, 0 to 2 percent slopes (DpA): This moderately well drained soil is on smooth
plains and is at a slightly lower elevation than well drained soils. Most areas cover 4 to 100 acres. This
soil has the profile described as representative of the series. Included with this soil in mapping are a
few small areas of soils that have a surface layer of fine sandy loam and loam. Also included are small
areas of Dunbar, Goldsboro, and Marlboro soils, small areas of soils that have a subsoil of sandy clay
that extends to a depth of less than 60 inches, and small areas of soils that have slopes of more than
2 percent. This soil is well suited to most locally grown crops. The main crops are tobacco, soybeans,
cotton, corn, forage crops, and small grain. Drainage may be required for some crops, such as tobacco.
This soil has good tilth and can be worked over a fairly wide range of moisture content. Tillage

operations, however, are delayed in wet seasons. Winter cover crops, minimum tillage, and crop
residue management help to maintain the tilth and organic -matter content. A seasonal high water table
and moderately slow permeability are the main limitations to use and management of this soil.
Goldsboro Loamy Sand, 0 to 2 percent slopes (GoA): This moderately well drained soil is on broad,
smooth interstream divides. Most mapped areas are generally broad and irregular in shape and cover
5 to 100 acres. Included with this soil in mapping are some mall areas of soils that have a surface layer
of sandy loam, fine sandy loam, and loamy fine sand. Also included are small areas of Duplin,
Lynchburg, and Norfolk soils, small areas that have a combined surface layer and subsoil less than 60-
inches thick, and small areas of soils that have slopes of more than 2 percent. This soil is well suited
to all locally grown crops. The main crops are tobacco, cotton, corn, soybeans, strawberries, forage
crops, and truck crops, such as snap beans, tomatoes, cucumbers, sweet potatoes, and onions.
Drainage may be required for some crops, such as tobacco. This soil has good tilth and can be worked
within a fairly wide range of moisture content. Tillage operation, however, are delayed in wet seasons.
Winter cover crops, minimum tillage, and crop residue management help to maintain tilth and the
organic -matter content. A seasonal high water table is the main limitation in the use and management

Lynchburg sandy loam, (Ly): This nearly level, somewhat poorly drained soil is on broad, smooth
plains. Most mapped areas cover 5 to 200 acres. Included with this soil in mapping are a few small
areas of soils that have a surface layer of fine sandy loam. Also included are small areas of Dunbar,
Goldsboro, and Rains soils, a few small areas of soils that have a subsoil of sandy clay loam that
extends to a depth of less than 60 inches, and a few small areas of soils that have a surface layer of
loamy sand, 20 to 40 inches thick, over a subsoil of sandy clay loam. This soil is well suited to most
locally grown crops if drained. The main crops are corn, cotton, tobacco, soybeans, strawberries, forage
crops, and truck crops, such as snap beans, tomatoes, cucumbers, sweet potatoes, and onions.
Drainage is required for crops such as tobacco. This soil has good tilth and can be worked within a
fairly wide range of moisture content. Tillage operations, however, are delayed in wet season. Winter
cover crops, minimum tillage, and crop residue management help to maintain tilth and the organic
matter content. A seasonal high water table is the main limitation in the use and management of this
soil.
Marlboro sandy loam, 0 to 2 percent slopes (MaA): This well -drained soil is on broad, smooth plains.
Most mapped areas cover 5 to 100 acres. This soil has the profile described as representative of the
series. Included with this oil in mapping are a few small areas of soils that have a surface layer of loamy
fine sand, loamy sand, and fine sandy loam. Also included are small areas of Aycock, Duplin, Faceville,
and Norfolk soils, some small areas of soils that have a subsoil that extend to a depth of less than 60
inches, and some small areas of soils that have slopes of more than 2 percent. This soil is well suited
to corn, cotton, tobacco, soybeans, and forage crops. The soil has no major limitation for use and

management. Growing winter cover crops and retuning crop residue help to maintain the organic -matter
content.
Norfolk loamy sand, 0 to 2 percent slopes (NoA) This well -drained soil is on broad, smooth plains
and is commonly on the highest part of the landscape. Most areas cover 5 to more than 400 acres. This
soil has the profile described as representative of the series. Included with this soil in mapping are a
few small areas of soils that have a surface layer of sandy loam, small areas of Goldsboro, Marlboro,
and Wagram soils, and some wet areas. Also included are small areas of soil that consist of more than
5 percent, by volume, plinthite within a depth of 60 inches, small areas of soils that have a subsoil of
yellowish -red to red sandy clay loam or sandy clay, and some small areas where the soils have slopes
of more than 2 percent. This soil is well suited to all locally grown crops. The main crops are corn,
cotton, tobacco, soybeans, forage crops, and truck crops, such as snap beans, tomatoes, cucumbers,
sweet potatoes, and onions. The soil has no major limitation for use and management. Winter cover
crops and crop residue management help to maintain the organic -matter content and conserve moister.
Norfolk loamy sand, 2 to 6 percent slopes (NOB). This well -drained soil is on gentle side slopes
between nearly level soils and soils on drainageways or bays. Most areas take in 5 to 40 acres. Included
with this soil in mapping are small areas of soils that have a surface layer of sandy loam, a few small
areas of Marlboro and Wagram soils, and a soil that has a yellowish -red to red subsoil. This soil is well
suited to all locally grown crops. The main crops are corn, soybeans, cotton, tobacco, and truck crops,
such as snap beans, tomatoes, cucumbers, sweet potatoes, and onions. Winter cover crops, minimum
tillage, and crop residue management help to control runoff and erosion and maintain the tilth and
organic -matter content. Maintaining drainageways in sod, using terraces and diversions, and including
close -growing crops in the crop rotation also help to conserve soil and water. Slope, surface runoff, and
erosion are the main limitations in the use of and management of the soil.
Wagram loamy sand, 0 to 6 percent slopes (WaB): This well -drained soil is on plains next to
drainageways and on broad, smooth ridges or between nearly level soils and soils on drainageways or
bays. Most mapped areas cover 5 to more than 300 acres. Included with this soil in mapping are some
small areas of soils that have a surface layer of sand, fine sand, or loamy fine sand and small areas of
Norfolk and Wakulla soils. Also included are some small areas of soils that have a sandy surface layer
more than 40 inches thick, small areas of soils that have more than 5 percent plinthite in the lower part
of the subsoil and within a depth of 60 inches. This soil is fairly well suited to most locally grown crops.
The main crops are corn, cotton, tobacco, soybeans, and forage crops. Low natural fertility, leaching of
plant nutrients, doughtiness, and soil blowing are the main limitations in the use and management of
this soil. Blowing sand may damage young plants. Winter cover crops, minimum tillage, and crop
residue management help to maintain the organic -matter content and conserve moisture.

3.2.2 HYDRAULIC LOADING RATE
The following water balance approach will be used in estimating hydraulic loading rates:
Drainage + Evapotranspiration + Runoff = Precipitation + Irrigation
A. Soil Drainage
The soil drainage at the proposed land application site is estimated using the geometric mean of
the reported saturated hydraulic conductivities (permeabilities) of the most restrictive soil horizon
multiply by 4% reduction factor. The soil drainage using the geometric mean of the reported
saturated hydraulic conductivities (permeabilities) of the most restrictive soil horizon multiplied by
4% reduction factor is estimated as follows:

Soil Drainage = 0.53 in/hr x 0.04 x 24hr/day x 30.4 days/month
= 15.47 inch/month
B. Evapotranspiration
The average monthly evapotranspiration rated used in the water balance are derived from the
publication "Weather and Climate in North Carolina", NC Agricultural Experiment Station, Bulletin
396, 1971.
C. Runoff
Runoff is assumed to be zero in the water balance calculation.
D. Precipitation
Using the precipitation data provided in the Soil Survey of Robeson County, published by USDA,
SCS, the 90th percentile yearly precipitation was used in water balance to derive hydraulic loading
rate (Table 8) and calculation of storage capacity requirement (Table 9).
E. Hydraulic Loading Rate and Required Field Area
From Table 8, using the water balance, the annual hydraulic loading rate is estimated to be 164.74
inch/year (13.73 ft/year).
Town of Pembroke - WWTP

3.2.3 LAND REQUIREMENT
Using the estimated 20-year wastewater flow projection of 2.0-MGD and the annual hydraulic loading rate
of 13.73 ft/year, the actual field area required for disposal of treated wastewater by land application is
estimated as follows:
Required Field Area, acres =
Annual HLR, ft/year
1,120 x Q, mgd
1,120x2.0mgd
13.73, ft/year
= 163 acres
Considering additional land area required for buffers, setback and access roads, a factor of 1.5 is used to
determine total land area required for the land application site. Accordingly, the total land area required for
the land application site is:
= 163 acres x 1.5
= 245 acres
3.2.4 STORAGE REQUIREMENT
Referring to Table 9, the maximum storage requirement is determined to be 3.72 inches. Accordingly, using
the water balance approach, the required storage capacity for a land application system is estimated as
follows:
Required Storage Volume = 3.72 inches x 163 acres x
acre -inch
27,152 gallons
= 16.5 million gallons
The above storage requirement does not account for inclement weather conditions (excessive precipitation,
windy conditions, freezing conditions, etc.), cover crop maintenance and site management activities when
land application of treated effluent cannot take place. Accordingly, as required by the State, at least 30 days
of storage of design effluent flow of 2.0-MGD will be provided. The required storage capacity is estimated
as follows:
Required Storage Volume = 2.0 mgd x 30 days
= 60 million gallons
3.2.5 COVER CROP SELECTION FOR LAND APPLICATION SITE
Fescue/Bermuda grasses over seeded with Rye grass in Winter months will be considered as cover crops
for the proposed land application system.

3.2.6 SRAY IRRIGATION SYSTEM
The spray irrigation system will consist of a spray irrigation pump station, flow metering and sampling, and
a solid set sprinkler type irrigation system. The spray irrigation piping will be arranged such that it will allow
the irrigation fields to be alternated for proper disposal of treated wastewater effluent by land application.
The sprinklers will be arranged such that the desired buffer zones are maintained and even distribution of
treated effluent on each spray irrigation field is achieved. This alternative also requires upgrades to the
existing plant to treat the projected 2-mgd demand.
3.2.7 DESCRIPTION
The principal components for this alternative are described as follows:
1. Provide new 9,000-LF of 16-inch forcemain for pumping the treated effluent from to 28-MG effluent
storage basin.
2. Provide earthen 28-MG storage basin with PVC liner to store treated effluent when land application

conditions at the land application site, and cover crop and land management activities at the land
application site.
3. Provide a spray irrigation pump station, necessary header lines and solid set sprinkler type spray
irrigation system. The spray irrigation pump station will include two (2) vertical turbine pumps each
rated at 3,500-gpm capacity and will be equipped with a manually controlled variable frequency
drive. The pump station will also be equipped with a magnetic flow meter and a sampler for
monitoring of irrigated flow and collection of irrigated water samples to determine hydraulic loading
rates and analysis of water samples as required by non -discharge permit issued by the NCDEQ.
4. Provide solid set sprinkler type spray irrigation system to irrigate total wetted area of 163 acres.
Based upon the water balance, the design annual irrigation or hydraulic loading rate for disposal of
decanted water by land application is 164.74 inch/year (3.17 inch/week). The cover crops at the
land application site will be coastal Bermuda grass over seeded with Rye grass in winter months.
5. Provide land and cover crops management equipment for the land application site.
6. Provide equipment storage and hay storage buildings or sheds at the land application site.

3.3 ALTERNATIVE 3: WASTEWATER REUSE
As a part of reduction or elimination of wastewater discharge to surface water, this alternative considers
the reclamation of wastewater effluent for distribution back to potential customers for non -potable uses.
These uses include commercial/industrial cooling water needs and other uses such as irrigation of athletic
fields, golf courses, etc. in the service area. As part of this evaluation, the Town was asked if there were
imminent commercial or industrial development at or near the Town that might create a demand for reuse
water. It was learned that there are no such projects anticipated. Also, the Town Manager was asked if
there had been any historical or current request or inquiries into the purchase of reclaimed water. These
investigations, failed to reveal any demand for water reuse or likely reuse customers. Therefore, considering
the factors such as: (1) lack of potential customers in the service area that require large quantities of
reclaimed water for coiling water needs, and (2) athletic fields are not located in close -proximity of the
reclaimed water source at the Pembroke WWTP, this alternative considering reclaimed water reuse in the
service area was removed from further consideration.
3.4 ALTERNATIVE 4: SURFACE WATER DISCHARGE THROUGH NPDES PROGRAM
This alternative considers disposal of the wastewater generated in the Town of Pembroke's service area
through the existing NPDES discharge into the Lumber River in the Lumber River Basin. The detailed
description and cost analysis of this alternative are provided as follows:
3.4.1 DESCRIPTION
The principal components for this alternative are described as follows:
1. Upgrade to existing influent pump station to provide capacity for increased flows up 5-mgd peaks.
2. Construction of new surge basin to equalize influent flows and loadings to the headworks.
3. Construction of new headworks, including mechanical screening and grit removal. New headworks
will be sized to handle 5-mgd peak flows.
4. Modification of oxidation splitter box to allow for diversion of influent flows to new oxidation ditch.
5. Construction of a new oxidation ditch to provide capacity for new 2-mgd ADF. Modification and
replacement of existing motors and rotor assemblies in existing oxidation ditches.
6. Modification of existing clarifier splitter box to allow for diversion of flows from oxidation ditch to
new secondary clarifier.
7. Modification to RAS/WAS pump station and associated piping to allow for operation of new
oxidation ditch.
8. Construction of a new secondary clarifier to bring operating capacity of 2-mgd.
9. Construction of two (2) new filters and UV disinfection system to meet future effluent limits.
10. Construction of new intermediate pump station.
11. Construction of new aerobic digester.

3.5 ALTERNATIVE 5: COMBINATION OF NPDES DISCHARGE AND LAND APPLICATION
This alternative considers disposal of the wastewater generated in the Town of Pembroke's service area
under the existing NPDES permit up to the current permitted capacity (1.33-mgd) and dispose of flows
above the permitted capacity via spray irrigation (0.66-mgd). The methodology for the spray irrigation
component is the same as describe in Alternative 2. The detailed description and cost analysis of this
alternative are provided as follows:
3.5.1 DESCRIPTION
The principal components for this alternative are described as follows:
1. Provide new 1,500-LF of 14-inch forcemain for pumping the treated effluent from to 20-MG effluent
storage basin.
2. Provide earthen 20-MG storage basin with PVC liner to store treated effluent when land application
of the cannot take place due to inclement weather conditions, not having desired groundwater level
conditions at the land application site, and cover crop and land management activities at the land
application site.
3. Provide a spray irrigation pump station, necessary header lines and solid set sprinkler type spray
irrigation system. The spray irrigation pump station will include two (2) vertical turbine pumps each
rated at 1.150-gpm capacity and will be equipped with a manually controlled variable frequency
drive. The pump station will also be equipped with a magnetic flow meter and a sampler for
monitoring of irrigated flow and collection of irrigated water samples to determine hydraulic loading
rates and analysis of water samples as required by non -discharge permit issued by the NCDEQ.
4. Provide solid set sprinkler type spray irrigation system to irrigate total wetted area of 81 acres.
Based upon the water balance, the design annual irrigation or hydraulic loading rate for disposal of
decanted water by land application is 164.74 inch/year (3.17 inch/week). The cover crops at the
land application site will be coastal Bermuda grass over seeded with Rye grass in winter months.
5. Provide land and cover crops management equipment for the land application site.
6. Provide equipment storage and hay storage buildings or sheds at the land application site.
7. Upgrade to existing influent pump station to provide capacity for increased flows up 5-mgd peaks.
8. Construction of new surge basin to equalize influent flows and loadings to the headworks.
9. Construction of new headworks, including mechanical screening and grit removal. New headworks
will be sized to handle 5-mgd peak flows.
10. Modification of oxidation splitter box to allow for diversion of influent flows to new oxidation ditch.
11. Construction of a new oxidation ditch to provide capacity for new 2-mgd ADF. Modification and
replacement of existing motors and rotor assemblies in existing oxidation ditches.
12. Modification of existing clarifier splitter box to allow for diversion of flows from oxidation ditch to
new secondary clarifier.

Erring Alternatives Analysis (EAA). Please note that the Division cannot guarantee
that an NPDES permit for an expanded discharge will be issued with these speculative
limits. Final decisions can only be made after the Division receives and evaluates a formal
permit application for the expanded discharge. In accordance with the North Carolina
General Statutes, the practicable wastewater treatment and disposal alternative with the
Least adverse impact on the environment is required to be implemented_ Therefore, as a
component of all NPDES permit applications for new or expanding flow, a detailed
ergineering alternatives analysis (EAA) must be prepared. The EAA must justify requested
fldws and provide an analysis of potential wastewater treatment alternatives. A copy of
Division. guidance for preparing EAA documents is attached.

Slate the Town of Pembroke is proposing an expansion >500,000 gpd flow, the Town
must prepare a SEPA document that evaluates the potential for impacting the quality of

Subject: RE: [External] NPDES Permit modification process
Hi, Carl —
You are correct in assuming that the expansion to 2.0 MGD would require a major modification of Pembroke's permit.
Also, because the 2013 spec limits were set by freezing the then -existing loads (meaning that most HQW requirements
do not apply), we believe those spec limits are still valid.
The process for expansions still calls for the POTW to request speculative limits for the increased discharge (optional but
recommended) and then request the permit mod to add limits for the new flow tier. Once the mod is issued, the
Permittee can submit plans and specs and request an ATC. Consistent with Rule 02H .0138, we usually do not act on ATC
requests until the permit has been issued. However, we have made limited exceptions if funding were at stake, if we did
Dt anticipate permit challenges, and if we had staff available to work on them. In those cases, we still would not pick up
the plans & specs before the permit went out for public review.
Your plan to submit plans and specs 6-7 months after the permit mod request is reasonable. We can't commit to a
schedule at this point, due to the permitting backlog, but I would note that it is our practice to give expansion requests
preference over routine permit renewals.
Let me know if you have any questions.

Hello John/Mikes/Nick/Min:
We are working on an upgrade for the Pembroke WWTP (NC0027103) from 1.33 MGD to 2.0 MGD (third
train). I assume this would be considered a major permit modification. I believe in the past, the NPDES
permit would have to be approved as a condition of reviewing the ATC. Our project is funded with EDA money
and has a certain schedule which may require review of the ATC while the NPDES permit application/EAA is
still potentially under review. I think we will submit the major modification permit application/EAA and then
about 6 to 7 months later be submitting the ATC application with plans and specs. The previous spec limits
are attached.
Can you please tell me what the current review process is for NPDES permits and ATCs and can you get started
reviewing ATCs while the NPDES permit application is still in review. Is there a possibility of getting a
response in the next few days? Thank you very much.

to the filtration system not working properly. Well #7 is the only well online for the town now. Well #6 is off line due to it feeds into
well #5. The town has experienced numerous leaks since well #7 has been the only water source for the town. Therefore, the town
started purchasing water from Robeson County on 12/27/2020 to help well #7 with the water demand.

UNC-P Technical Memorandum for Water and Sewer Infrastructure
(2011)

Technical Memorandum
Subject: University of North Carolina at Pembroke Master Plan Memorandum
Prepared for: Sasaki Associates, Inc.
Prepared by: Matthew West, PE — Dewberry & Davis, Inc.
Virginia Russell, PE — Dewberry & Davis, Inc.
Steve Webb, PE — Dewberry & Davis, Inc.
Date: June 28, 2011
I. INTRODUCTION AND PURPOSE
The University of North Carolina at Pembroke (UNCP) is located in Robeson County, North Carolina on a
151 acre campus. The current enrollment at UNCP is approximately 6,900 students. UNCP is currently
in the process of updating the campus master plan which will be utilized to guide future development on
the campus.
This master plan technical memorandum (memo) evaluates the stormwater, water, sewer, and
information technology (IT) infrastructure of the campus. The memo is based on information that UNCP
has currently provided to Dewberry & Davis, Inc. (Dewberry). No additional field investigations or
analyses have been performed as part of this memo. Dewberry met with Mr. Steve Martin AIA, UNCP
Assistant Vice Chancellor of Business Affairs/Facilities Management, on April 19, 2011 and June 15, 2011
to review known issues and limited information. Current drawings of the campus utilities, record
drawings of various campus improvements, fire flow data, and sewer lift station data and associated
permits will be provided to Dewberry by UNCP in the future.
The purpose of the memo is to provide UNCP with existing utility conditions and issues associated with
potential campus expansion. Additionally, recommendations and policy suggestions for future studies
and efficiency opportunities are included. Preliminary planning level recommendations for
improvements to the stormwater, potable water, sanitary sewer, and IT standards have been evaluated.
II. OVERVIEW
Stormwater infrastructure and nuisance flooding are significant issues. The master plan addresses these
issues with additional landscaped areas, swales, rooftop water management, and reforestation. There
may be capacity for expansion in potable water, sanitary sewer, and IT. However, for all systems,
additional studies are needed to properly assess the condition and capacity of existing infrastructure.
Specific recommendations are described in section IV.

Technical Memorandum
III. EXISTING UTILITY SYSTEMS AND ISSUES
a. Stormwater
UNCP operates and maintains the stormwater infrastructure within the UNCP campus.
According to documented reports and visual observations from staff, the campus is frequently
experiencing "nuisance" flooding. The flooding has occurred in various areas on campus, with
the most extreme cases located near Faculty Row and Oak Hall.
It is our understanding that UNCP currently addresses stormwater volume and quality control
on an individual project basis. Best Management Practices (BMPs) have been implemented on
the most recent construction projects. Certain additional measures, like adding underground
storage, have been put in place to alleviate flooding. It is also our understanding the UNCP does
not currently have a stormwater master plan in place.
Stormwater drainage generally flows west to east across campus. West of campus, stormwater
drainage is collected in various culverts and channels, and piped under University Row and
through campus. East of campus, stormwater outfalls under Odum Road into a series of
channels, eventually flowing to Bear Swamp. Bear Swamp has a typical ground surface elevation
of 162 feet. The typical ground surface elevation on campus is approximately 172 feet. The
delineation of the existing drainage basins in included in Exhibit A.
From field observation, it is apparent that the downstream channels are not maintained on a
regular basis. Pipes are clogged with sediment, channels are overgrown, and manmade dams
have been added for vehicle access, blocking flow in the stormwater channels.
b. Potable Water
UNCP operates and maintains potable water mains within the campus. Potable water is
supplied to the campus by the Town of Pembroke (Town). During our April 19, 2011 meeting
Mr. Martin noted that the southern portion of campus has aging water infrastructure. Many of
these water mains are 75-100 years old and the material is asbestos cement (AC) pipe. AC pipe
of this age can become brittle, and also become a maintenance headache. Water mains located
on the northern portion of campus are generally much newer and are either made of ductile
iron or polyvinyl chloride (PVC).
A project to replace the aging water mains on the southern part of campus was begun 5-10
years ago. The project was taken to a design development level but was eventually cancelled
due to costs and lack of funding.
Dewberry'
Page 2of12

Technical Memorandum
In 2009, UNCP constructed a 300,000 gallon elevated water storage tank to increase fire
protection capacity on the UNCP campus. Prior to the construction of the elevated water
storage tank, UNCP had limited fire protection capacity, preventing the construction of
additional buildings on campus. Based on conversations with Mr. Martin, the UNCP campus
generally has adequate water pressure for average and peak domestic demands. Since the
construction of the elevated water storage tank, it appears there is adequate volume and water
pressure for fire protection for the current number of buildings on campus.
c. Sanitary Sewer
UNCP operates and maintains sanitary sewer mains and lift stations within the campus. The
Town provides wastewater treatment for UNCP. Like the water system, the oldest sanitary
sewer infrastructure is located on the southern portion of campus. Many of these sanitary
sewer mains are 75-100 years old. Sanitary sewer mains located on the UNCP campus are
mostly cast iron or ductile iron pipe.
Mr. Martin noted during our meeting that there are no capacity issues with the sanitary sewer
system other than standard operational and maintenance issues. Additionally, it appears there
are no significant inflow and infiltration (I&I) issues associated with the sewer system.
d. IT
The IT infrastructure at UNCP supports all data and standard voice communications for the
campus. The core backbone of the system consists of a fiber optic ring between the primary
main distribution frame and data center located in Oxendine Science Building and the secondary
main distribution frame and data center located in Lumbee Hall. Almost all buildings on campus
are connected to the fiber ring, while a few on the perimeter of campus, such as Carter Hall, are
served by point-to-point wireless systems.
The existing fiber optic loop cabling was installed during the 1980s and according to Robert Orr,
the Chief Information Officer; the fiber has become brittle and difficult to work with. Also, the
cable was cut once and the University has experienced issues from the repair splicing. The
University desires to include planned replacement of the fiber optic cabling in the master plan.
While the network topology and switching is fully redundant, the network reliability is limited by
the pathway infrastructure. Almost every building on campus has a single telecommunications
ductbank entrance into its building distribution frame. If this ductbank was cut during
construction the entire building would lose data and voice communications until it could be
repaired. Inclusion of dual telecommunication entrance ductbanks for new buildings in the
master plan is desired. The point-to-point wireless systems used for communications with
outlying buildings have limited bandwidth and are not as reliable. As more services, such as
Dewberry.
Page 3 of 12

Technical Memorandum
video and security, are moved to the IT network the wireless systems will become less effective.
The master plan will need to include extending fiber to the campus perimeter.
In discussions with Kevin Pait, Director of Network and System Administration, it is our
understanding that the University has been in discussions with MCNC concerning the routing of
the Golden LEAF Rural Broadband Initiative (GLRBI) fiber optic lines and duct infrastructure
through Pembroke. The proposed routing goes north from 3rd Street on Prospect Road, turns
west on Physical Plant Drive, continues around the northwest edge of campus, and connects to
University Road where it turns south and meets back up with 3`d Street. Parts of the discussions
with MCNC have included provisions in the ductbank infrastructure for use by UNCP. It is
recommended that the University extend ductbank along Old Main Road between Prospect
Road and University Road connecting to the GLRBI infrastructure. This will provide a complete
circular infrastructure around a majority of campus allowing an outer fiber optic ring to be
constructed. A new linked outer ring along with replacement of the existing fiber optic loop will
significantly increase the reliability and uptime of the University IT systems.
As the campus continues to expand a new main distribution frame and data center will be
required at the northern end to supplement the existing centers at Oxendine Science Building
and Lumbee Hall. Originally IT has planned to incorporate a center in the future Info Commons
facility; however, the proposed location at the current site of Wellons Residence Hall and Jacobs
Halls is too close physically to Oxendine Science Building to provide desired infrastructure
separation. The new data center could be located in Allied Heath building or the future Business
School.
IV. RECOMMENDATIONS AND FUTURE STUDIES
a. Stormwater
Recommended future studies of the stormwater system include:
• Collection of current, accurate inventory of the stormwater system and existing BMPs
and control features.
• Hydraulic and Hydrologic Modeling of campus and the adjacent sub basins to assess the
general response of the watersheds for a range of rainfall events and different land use
conditions.
• Development of a stormwater master plan to evaluate conceptual design alternatives
and identify the most reasonable, cost-effective solutions for the system.
Development of a master stormwater model will assist UNCP in identifying areas on campus
where drainage improvements can be made to alleviate flooding. It will also help UNCP identify
Dewberry'
Page 4 of 1

Technical Memorandum
offsite improvements that need to be made to provide relief to the campus during a rain event.
It is crucial the UNCP work closely with the Town and Robeson County since we anticipate "buy -
in" from the adjacent property owners will be vital.
Preliminary recommendations for stormwater improvements on campus include:
• BMP's— BMP's can be utilized to minimize localized nuisance flooding and enhance the
water quality of stormwater runoff. Further development of the campus master plan
will help identify areas where BMP's are appropriate.
• Reduction of Impervious Surface Area — Reducing impervious surface area will allow
some of the stormwater runoff that typically accumulates on campus to seep into the
ground. One example would be the exchange of the parking adjacent to Welion's
Residence Hall for a BMP and/or landscaped area.
• Vegetation Establishment — Establishing vegetation on campus will help enhance the
water quality of the stormwater runoff on campus. Vegetation will also help promote
uptake of stormwater runoff and may help control localized nuisance flooding.
One critical stormwater improvement will be implementing localized BMP's. There are various
site constraints on the UNCP campus to consider when selecting a BMP including:
• Contributing drainage area
• Real estate availability
• Relief (elevation difference) across the basin
• Shallow water table
• Poorly draining soils
The North Carolina Department of Environment and Natural Resources (NCDENR) identifies
some BMP's that work well with the constraints listed above including:
1. Stormwater Wetlands — per the NCDENR Stormwater BMP Manual "constructed
wetlands are constructed systems that mimic the functions of natural wetlands and use
physical, chemical, and biological processes to treat stormwater pollution." The
stormwater wetland will also provide peak runoff attenuation and runoff volume
management.
o Advantage — can be aesthetically pleasing if properly maintained and can
provide a good opportunity to incorporate landscaping and education into the
BMP
o Disadvantage — requires more real estate than typically detention facilities
2. Wet Detention Basins — per the NCDENR Stormwater BMP Manual "a wet detention
basin is a stormwater management facility that includes a permanent pool of water for
Dewberry
Page 5 of 12

Technical Memorandum
removing pollutants and additional capacity above the permanent pool for detaining
stormwater runoff." A wet detention basin will provide peak runoff attenuation and
runoff volume management.
o Advantage — can be aesthetically pleasing when properly maintained and can
provide a good opportunity to incorporate landscaping and education into the
BMP
o Disadvantage — can be a nuisance if not properly maintained
3. Grassed Swales — per NCDENR Stormwater BMP Manual "a water quality grasses swale
is a shallow open channel drainage way stabilized with grass or other herbaceous
vegetation that is designed to filter pollutants." Grassed swales must be used with
other BMP's to achieve significant runoff volume management.
o Advantage — can reduce the cost of traditional curb and gutter infrastructure
c Disadvantage — can be subject to standing water and encourage mosquitoes
4. Rooftop Runoff Management— per NCDENR Stormwater BMP Manual "rooftop runoff
management is the development of vegetated roof covers and roof gardens, roof
ponding areas and cisterns to detain and promote evapo-transpiration of runoff
originating from roofs." Rooftop runoff management can reduce the impervious surface
and ultimately reduce the runoff from the roof.
o Advantages — reduces heat island effect, adds aesthetic value, conserves space,
runoff collected in cisterns can be reused for irrigation on campus
o Disadvantages — difficult to retrofit existing facilities, maintenance is required,
can be costly
Incorporating localized BMP's on campus could also provide educational opportunities to
students and faculty. Educational exhibits could be an opportunity for students and staff to
learn about the function and purpose of the BMP. Enhanced landscaping and pedestrian
friendly walkways near the BMP will also help contribute to a "park like" setting.
The current stormwater piping network on campus appears to be significantly undersized to
handle the stormwater runoff from campus plus the additional offsite flow that is passing
through campus. Current inventory shows pipes as small as six (6) inches with minimal slopes.
Typically, we provide a minimum of eighteen (18) inch diameter storm pipes.
Based on the inventory provided to Dewberry, it appears that the offsite flow and the onsite
flow share a stormwater piping network. After a hydrologic and hydraulic analysis is completed,
recommendations may include strategies for developing separate stormwater conveyances to
bypass offsite flow and increasing the existing stormwater piping network capacity by upsizing
existing pipes or adding additional stormwater piping.
Dewberry.

Technical Memorandum
We also recommend the campus, in collaboration with the Town and NCDOT; develop a routine
plan for maintenance of the existing stormwater infrastructure. The existing downstream
culverts are currently clogged with debris and sediment. Also, the existing downstream ditches
are blocked with earthen dams and are full of storm debris. The current downstream conditions
appear to be significantly impacting the stormwater infrastructure on campus. Basically, during
a large rain event, the water has nowhere to go and backs up in the system and causing flooding
on campus.
b. Potable Water
Recommended future studies of the potable water system include:
• Updated mapping of the existing water system.
• Hydraulic model of the existing water system.
• Sizing and replacement of aging infrastructure after evaluating the water hydraulic
model.
Average daily demands for the future buildings were calculated based on the 15A NCAC 2T rules.
The 15A NCAC 2T rules document standard flow rates to use for average daily sanitary sewer
demands. For the purposes of this technical memorandum it has been assumed that the
average daily water demand is the same as the average daily sewer demand. Documentation of
the demand calculations are included in Appendix B. Based on a review of the existing water
system in the vicinity of each of the nine (9) future buildings, the following determinations were
made:

Technical Memorandum
These determinations show that the majority of water mains could potentially accommodate
increased demand based on average demands for the proposed buildings and the existing water
mains that would serve each building. Current and future potable water corridors are shown in
Appendix C.
A hydraulic water model should be developed to determine the exact size service line required
for each building and also to determine if minimum flow and pressure would be available during
peak domestic demand fire flow scenarios. Additional information for each building regarding
fire protection requirements should be incorporated in sizing the water main to each building so
that if a separate fire protection service to the building is necessary, it can provide adequate
flow and pressure to the fire protection pumps and equipment for each building.
As previously discussed, it is recommended that all AC pipe be replaced with ductile iron (DI)
pipe or PVC pipe, when possible. Also, it is recommended that any new building service not be
connected to existing AC water mains, if possible.
Regularly scheduled routine maintenance of the water infrastructure should also be
implemented. Hydrant/system flushing programs, valve turning programs, hydraulic studies and
modeling, along with scheduled capital improvement projects to replace aging water mains will
help to prolong the service life of water mains (and associated appurtenances) and also
maintain and/or improve water quality on campus.
Water efficiency programs should also be implemented to reduce water consumption, especially
in times of drought. Future buildings could be designed to use low flow fixtures and recycle gray
water for landscaping, existing buildings could be retrofitted to use low -flow fixtures, future
landscaping should include more drought -tolerant plants, and systems to capture and reuse
stormwater from the building. Educational programs can also be implemented for students,
faculty, and staff on campus to teach the importance of reducing water consumption and ways
this can be accomplished.
c. Sanitary Sewer
Recommended future studies of the sanitary sewer system included:
• Updated mapping of the existing sanitary sewer system.
• Hydraulic model of the existing sanitary sewer system.
Average daily demands for the future buildings were calculated based on the 15A NCAC 2T rules.
The 1SA NCAC 2T rules document standard flow rates to use for average daily sanitary sewer
demands. Documentation of the demand calculations are included in Appendix B. Based on a

No infrastructure available
According to 15A NCAC 2T regulations regarding minimum sizing for private gravity sewer lines,
there shall be no private gravity sewer conveying wastewater less than 6 inches in diameter.
Governing regulations may require that some of the existing gravity sewers be upsized prior to
connecting new buildings to them. The current and future sanitary sewer corridors are shown in
Appendix D.
Additionally, if the new buildings require connection to an existing force main, both the existing
pump stations and force main should be evaluated to determine if adequate capacity and
pressure remains to support the new building.
A hydraulic sewer model should be devleoped to determine the exact size service line required
for each building and also to determine if downstream mains and manholes could accommodate
the increased flows.
Regularly scheduled routine maintenance to the sewer infrastructure should also be
implemented. Manhole and cleanout inspection programs, regular inspection and maintenance
of pumps and pump stations, reduction of fats, oils, and grease (FOGs) throughout campus,
education of students, faculty, and staff regarding wastewater processing (what not to flush or
pour down sinks), along with scheduled capital improvement projects to replace aging sewer
mains will help to prolong the service life of sewer services, mains, and manholes.

Technical Memorandum
d. IT
In discussions with Kevin Pait, Director of Network and System Administration, it is our
understanding that the University has been in discussions with MCNC concerning the routing of
the Golden LEAF Rural Broadband Initiative (GLRBI) fiber optic lines and duct infrastructure
through Pembroke. The proposed routing goes north from 3rd Street on Prospect Road, turns
west on Physical Plant Drive, continues around the northwest edge of campus, and connects to
University Road where it turns south and meets back up with 3`d Street. Parts of the discussions
with MCNC have included provisions in the ductbank infrastructure for use by UNCP. It is
recommended that the University extend ductbank along Old Main Road between Prospect
Road and University Road connecting to the GLRBI infrastructure. This will provide a complete
circular infrastructure around a majority of campus allowing an outer fiber optic ring to be
constructed. A new linked outer ring along with replacement of the existing fiber optic loop will
significantly increase the reliability and uptime of the University IT systems.
As the campus continues to expand a new main distribution frame and data center will be
required at the northern end to supplement the existing centers at Oxendine Science Building
and Lumbee Hall. Originally IT has planned to incorporate a center in the future Info Commons
facility; however, the proposed location at the current site of Wellons Residence Hall and Jacobs
Halls is too close physically to Oxendine Science Building to provide desired infrastructure
separation. A location for the new center will need to be determined.
V. CONCLUSIONS
a. Stormwater
• Based on preliminary review, it appears that the existing stormwater piping
network on campus is significantly undersized. Hydrologic and hydraulic
modeling should be utilized to determine suitable improvements that need to
be made to the existing system. Improvements may include bypassing offsite
flow and upsizing the existing stormwater infrastructure.
• Some improvements that can be made on campus include reducing
impervious surface area, establishing vegetation, and creating BMP's where
practical to address stormwater quantity and quality control.
• Regular routine maintenance should be implemented and performed on
upstream, downstream, and campus stormwater infrastructure. The
maintenance plan should include buy in from the Town and NCDOT.

Technical Memorandum
b. Potable Water
• Some of the existing water infrastructure could potentially supply a portion of
the nine (9) future buildings without major renovations or replacements.
• In general, all existing water mains that are AC material should be replaced
with DI or PVC.
• A water hydraulic model should be utilized assist in sizing the water service to
each building and determine the effects of the overall water system on
campus. This model will also assist in determining compliance with local and
State code regarding minimum standards for fire protection.
c. Sanitary Sewer
d. IT
• Analysis of regulations governing private sewer systems will be required when
determining connections between future buildings and the existing gravity
sewer infrastructure.
• Analysis of the existing pump station and force mains on campus will be
required to ensure capacity is available for connections with services to future
buildings.
• A sewer hydraulic model should be developed to size the sewer service to
each building and determine the effects of the overall sewer system on
campus.
• A phased plan for the replacement of the existing fiber optic loop cabling will
need to be developed.
• Location of new main distribution frame and data center needs to be
determined.
• The University needs to push for and take advantage of the additional pathways
provided by MCNC under the Golden LEAF Rural Broadband Initiative (GLRBI).
e. Water and Energy Efficiency
• Water efficiency programs should also be implemented to reduce water
consumption, especially in times of drought. Future buildings should be
designed to use low flow fixtures and recycle gray water for landscaping.
Existing buildings could be retrofitted to use low -flow fixtures. Future
landscaping should include more drought -tolerant plants, and create

MAP INFORMATION
The soil surveys that comprise your AOI were mapped at
1:20,000.
Warning: Soil Map may not be valid at this scale.
Enlargement of maps beyond the scale of mapping can cause
misunderstanding of the detail of mapping and accuracy of soil
line placement. The maps do not show the small areas of
contrasting soils that could have been shown at a more detailed
scale.

Coordinate System: Web Mercator (EPSG:3857)
Maps from the Web Soil Survey are based on the Web Mercator
projection, which preserves direction and shape but distorts
distance and area. A projection that preserves area. such as the
Albers equal-area conic projection, should be used if more
accurate calculations of distance or area are required.
This product is generated from the USDA-NRCS certified data as
of the version date(s) listed below.

The orthophoto or other base map on which the soil lines were
compiled and digitized probably differs from the background
imagery displayed on these maps. As a result, some minor
shifting of map unit boundaries may be evident.

Alt. 2: Soil Survey of Robeson County — Precipitation Info

ROBESON COUNTY, NORTH CAROLINA 65
16 gives information on the probability of freezing
temperatures in spring and fall. In the nearly 70 years
that records have been kept, the temperature at Lum-
berton has never been as low as 0° F. The highest
temperature on record is 108°. The temperature reaches
100° in only about half the summers, but it rises to
90° or higher on more than half the days in each
summer.
A large part of the rainfall during the growing
season comes from summer thunderstorms and there-
fore varies widely from year to year, season to season,
month to month, and even from place to place in the
county. There can be periods of 5 to 20 days when
local areas have no significant rain while other areas
nearby have substantial showers. In such cases, irri-
gation may be worthwhile.
Frequently in autumn and occasionally in summer,
tropical storms pass through the coastal waters or
inland and increase rainfall. In dry seasons such rains
may be beneficial.
Rainfall in winter generally results from low-
pressure storms passing through or near the area and
is less variable than in summer. Although several days
may pass without significant rain, this is less important
in winter because of the lower evaporation and trans-
piration.
A little snow or sleet occurs almost every winter, but
the accumulation is ordinarily small and melts in a few
hours. The blanketing effect of a layer of snow lasting
several days is extremely rare. About once in 10 years,
on the average, as much as 8 inches may accumulate;
perhaps one in three of such rare accumulations may
remain on the ground a week or more.
Cloudiness is variable; the sun shines, on the aver -

Hello,
I am not aware of anyone who could use such water.
No one has reached out to my knowledge.
We do have one SIU (Steven Roberts Desserts — a bakery); I don't know that they would have an
interest though.
Thanks,

Subject: Pembroke - WWTP Expansion
Good morning Tyler, as part of the NPDES permitting process for the expansion, the NPDES Unit requires the completion
of an Engineering Alternative Analysis. As part of this. they require an evaluation of treating the effluent to a
reclaimedireuse quality water for distribution back to users in -lieu of potable water. These users would use this water for
manufacturing processes, cooling tower water, irrigation. toilet water, and other non -potable uses. Are you aware of any
large water users that has reached out to the Town that may have expressed interest or questioned if the Town treats to
that quality of effluent? Do you think there would be much demand or desire for this type of water in Town?
Thanks!
