Michael,
Please find enclosed one bound copy of the addendum to the initial renewal request for the
Town of Pittsboro's NPDES permit#NC0020354—with the co-permittee, Chatham Park
Investors LLC(CPI).
Since the second submittal on August 26, 2020, CPI has decided on a name change for
their new facility. The new facility will be named - Chatham Park Water Recovery Center
(CPWRC). I have updated the name change throughout the application and the narratives.
As always, Nick has been very helpful in assisting me with this modification and answering all
of our questions.
Please feel free to call with any questions.
Thank you,

Re: Addendum to NPDES Permit Renewal Application
Request
We appreciate the opportunity to meet on January 14, 2020 to discuss the application of the Town of Pittsboro ("Town"
or "Pittsboro") for renewal of its NPDES Permit and the associated permitting of the Chatham Park Investors Facility
under the Town's NPDES Permit.Attached is the Town's revised NPDES Permit renewal application based on the
discussion and agreement at the conclusion of the meeting, with the Town and Chatham Park Investors LLC ("CPI") as
co-applicants. CPI and the Town have entered into a Master Services Agreement for CPI to construct a wastewater
treatment facility (the "Facility") for treatment of up to 0.499 MGD of wastewater per day to serve the Town's future
residential and non-residential customers in a service area described in the Master Services Agreement. CPI Wastewater
treated at the CPI Facility can be discharged by one or both of the following alternatives: returned to the CPI Facility
service area as reclaimed water; or transmitted to the existing Town wastewater treatment facility ("Pittsboro WWTP")
for further treatment and use by the Town to serve an existing reclaimed water customer or for discharge into Robeson
Creek pursuant to the Town's NPDES Permit.The attached application has been updated onto the new 2A NPDES forms,
and now identifies the Town and CPI as co-applicants.
It is our recommendation that the NPDES permit be structured with the following considerations:
1. Flow— Compliance based on combined discharge from both facilities.
2. Concentration based limits—The Town and CPI Facility each will monitor and be responsible for meeting
the concentration limits at its respective facility.
3. Mass Based limits—Compliance based on combined discharge from both facilities.
Background Information
Coordination of projects and approvals probably involves consideration of the following operations,
planned/proposed improvements, and DEQ approvals:
OPERATIONS
Currently permitted operations. Currently, the Pittsboro WWTP is permitted to discharge up to 0.75 MGD to
Robeson Creek which is in the Jordan Lake Watershed (NPDES permit NC0020354) and is permitted to divert up to 0.3
MGD of treated wastewater for reuse (reclaimed water system permit number WQ0024838). Pittsboro's collection
system (permit number WQCS00146, and related collection system extension permits) currently delivers untreated
wastewater to the Pittsboro WWTP. The City of Sanford's WWTP (permit number NC0024147) currently receives
untreated wastewater from Sanford's collection system (permit number WQCS00047).
Currently permitted future operations. The Pittsboro NPDES permit,conditioned on issuance of ATCs and receipt
of engineer's certifications, authorizes a 1.249 MGD discharge to Robeson Creek(to replace the 0.75 MGD discharge)and
the 1.971 MGD discharge to the Haw River, providing a total permitted wastewater management capacity of 3.22 MGD.
4824-3953-1421.v3

Planned/proposed operations. The planned operations are the following:
1. First, complete construction of the new CPI Facility and the effluent force main to the Pittsboro WWTP.
The CPI Facility will provide treatment services for wastewater received from the CPI Facility service area
(initially up to 0.499 MGD of treated wastewater). Wastewater treated at the CPI Facility can be
discharged by one or both of the following alternatives:(i) returned as reclaimed water to the Town's new
reclaimed water distribution system that will serve properties in the CPI Facility service area; or (ii)
conveyed to the Pittsboro WWTP for further treatment and use by the Town to serve an existing reclaimed
water customer or for discharge into Robeson Creek (outfall 001) pursuant to the Town's NPDES Permit.
Treated wastewater from the CPI Facility to be discharged into Robeson Creek will be combined with
effluent from the Town's WWTP just prior to discharge. The quality of the effluent exiting the CPI Facility
and the Pittsboro WWTP will be monitored individually, and limited monitoring of the combined effluent
may be required. The configuration of this interconnection has been coordinated internally among staff
and consultants,and will be finalized during the NPDES application review and comment period.
2. Both facilities will continue to operate and discharge to Outfall 001 until completion of Phase 2 - the
Pittsboro to Sanford force main project.
3. Pittsboro's collection system will then divert up to 2 MGD of untreated wastewater to the Big Buffalo
WWTP in Sanford through the new force main to be constructed upon DWI loan approval, where it will
be treated and then discharged downstream of the Lake Jordan Watershed and the Haw River. The
, Pittsboro WWTP will be updated to provide additional wet weather flow equalization for raw wastewater
using infrastructure that is currently part of the Pittsboro WWTP. This includes use of the existing 0.6 MG
equalization tanks and conversion of the existing treatment tanks to equalization to provide an additional
0.5 MG (total of 1.1 MG). The conversion will include new equalization pumping to the EQ tanks,
automated diversion valves,new aeration diffusers for the converted tanks,and pipe and control changes.
4. Upon completion of the Pittsboro to Sanford force main,wastewater being collected at the Pittsboro site
will no longer be treated and will be pumped to Sanford. The Pittsboro pump station will continue to
receive treated wastewater from the CPI Facility for discharge as described in paragraph 1.
The resulting near-term Pittsboro wastewater management capacity, with all planned operations in place, will be 2.499
MGD. See the attached flow charts (Attachment 1 &2) for a conceptual overview of the proposed/planned operations.
Long-term,Pittsboro's foreseeable wastewater treatment capacity will be 5.22 MGD(2 MGD from Pittsboro-Sanford force
main and 3.22 MGD from full implementation of infrastructure authorized by the Town's NPDES permit).

Narrative for Form 2A
Town of Pittsboro & Chatham Park Investors
Form 2A is structured to address permitting of one facility and one applicant. For Pittsboro,the new
situation will be two facilities with one shared discharge point and co-permittees. Some parts of Form
2A do not fit this scenario.This narrative is intended to provide clarification for certain sections of the
form that are not easily/clearly answered with the choices provided.
The Town of Pittsboro is contracting with the Chatham Park Investors LLC to provide wastewater
services for new development within the Town.The Town of Pittsboro, along with the Chatham Park
Investors LLC, are applying as co-permittees.The intent is for the discharge of Outfall 001 to be
distributed as 0.75 MGD for the existing Pittsboro WWTP and 0.499 MGD for the new Chatham Park
Water Recovery Center(CPWRC).The remainder of the permit, 1.97 MGD to Outfall 002,will remain
solely with Pittsboro for future use.
In order to be clear about the design,treatment,and operation of each plant,the entire application has
been completed for each individual facility but signed by both applicants. Pittsboro has two outfalls, and
both have been included with the Pittsboro WWTP application,while only 0.499 mgd of outfall 001 has
been included with the CPWRC application.
Section 1.3: Both the Town of Pittsboro&Chatham Park Investors LLC are applying to be co-permittees
for the NPDES permit renewal for discharge to outfall 001. Both names and addresses have been listed
in this section.
It should be noted that The Town of Pittsboro("Pittsboro")entered into a new "Master Services
Agreement"with Chatham Park Investors LLC("CPI") in August 2020 to acquire wastewater treatment
services from the new CPWRC, which also has been referred to in previous documents as Chatham Park
Decentralized Water Resource Recovery Facility(WRRF).
Section 1.4:The applicants will be both the Town of Pittsboro&Chatham Park Investors LLC(CPI). CPI
will own and operate the new facility; named the Chatham Park Water Recovery Center.The Town of
Pittsboro will own and operate the existing Pittsboro WWTP.
Section 1.5:Correspondence should be sent to both applicants.
Section 1.10:The Annual Average Flow Rate for Pittsboro has been determined by using the plant
effluent meters.The discharge to Roberson Creek has been added to the pumped reclaimed water to
determine the total effluent leaving the plant each day. For 2019,this resulted in an average daily flow
of 0.498 mgd leaving the plant. See process flow diagram in section 2.4 for meter locations.
Section 1.16: For the CPWRC, effluent will be transported to another facility(Pittsboro WWTP) but not
for treatment prior to discharge into Roberson Creek. If the effluent is used for reclaimed water,then
chlorine will be added before it is pumped to the Pittsboro reclaimed water customer.
Section 2.3:A topo map has been provided for each facility along with maps showing the phases listed
in Section 2.5.
FORM 2A NARRATIVE 1

Narrative for Form 2A
Town of Pittsboro & Chatham Park Investors
Section 2.4 For the CPWRC application,the complete report from McKim &Creed has been included;
"Chatham Park Decentralized Water Resource Recovery Facility(WRRF) Preliminary Basis of Design
Report" dated July 31, 2019. An updated process flow diagram has also been included.
For the Pittsboro application,an updated process flow diagram has been included that shows the
proposed discharge tie-in point of the CPWRC to outfall 001.This is Phase 1 listed in Section 2.5.This
design is not yet complete but shows the most recent plan revision.A second Pittsboro process flow
diagram has been included that shows the basic tie-in of the proposed pump station/force main to the
Sanford project—this is Phase 2 listed in Section 2.5.
Section 2.5:The first improvement listed for both applicants is the construction of the CPWRC and its
discharge to Pittsboro WWTP Outfall 001.The new facility is currently under construction with permit
#WQC0039375.The force main that transports this treated effluent to the Pittsboro WWTP is currently
under construction with a zero-flow permit#40514.The final design for the tie-in of the effluent force
main to the Pittsboro plant is currently under review by Pittsboro Staff and has not yet been approved.
It is anticipated that the final design of the tie-in point will be submitted along with the application for
an authorization to construct(ATC)for the new CPWRC. Both plants will operate using Outfall 001 until
completion of the second improvement for the Pittsboro WWTP.
The second improvement listed for Pittsboro is the construction of a pump station and force main that
will convey up to 2.0 MGD of untreated wastewater to the Big Buffalo WWTP in Sanford. This project
will include repurposing and converting some of the Pittsboro WWTP infrastructure (e.g.,
equalization and treatment tanks)to provide additional wet weather flow equalization.
Once completed, untreated wastewater from the existing Pittsboro service area and parts of the future
CPWRC service area, will be pumped to the Sanford facility. At that time,effluent from the CPWRC will
either be used to supply Pittsboro's reclaimed water customer,3M,or discharged to Roberson Creek.
The Sanford project is currently under review by the Division of Water Infrastructure.
The raw sewage force main from the CPWRC to the Pittsboro plant is also currently under construction
with permit#40514.This force main is intended to be used when the pump station is complete but is
being installed parallel to the treated effluent force main.This will allow flexibility during start-up of the
new CPWRC. If there are difficulties during start-up, effluent can be diverted into the raw sewage force
main and treated at the Pittsboro WWTP. Afterwards,this line will not be used until the Pittsboro pump
station is operational and the raw sewage will be pumped to Sanford. (This raw sewage force main is
being installed in Phase 1 for start-up emergencies, but is intended to be operated during Phase 2.)
Section 3.8:The Pittsboro WWTP has been modified over the years and the"Design Removal Rates" are
unknown. In order to provide the removal rate needed for this Table,the 2019 DMRs were used to
compare the influent sampling of BOD and TSS to the effluent sampling. Using the monthly average,the
plant had a 99%removal rate for both BOD&TSS in 2019. It should be noted that this% removal rate is
lower when flow through the plant exceeds the Design Flow of 0.75 mgd. Influent sampling is only
conducted for BOD&TSS,therefore%removal rates for phosphorus and nitrogen could not be
calculated.

In order to clarify the discharge to Outfall 001 during the two phases of development listed in Section
2.5,the Table in Section 3.8 has been completed by Phase and by Facility. This has been noted in the
row entitled "Design Removal Rates by Outfall." During Phase 1, both plants will discharge to Outfall
001. During Phase 2, only the CPWRC will discharge to Outfall 001.
Section 3.9: UV information for the Pittsboro WWTP has been attached in the Appendix. 1
1 Section 3.16: Each facility has a design flow less than 1.0 mgd, but the total discharge to Outfall 001 will
be greater than 1.0 mgd. The Town completed a Priority Pollutant Scan in July 2019 and the test results
are attached to meet the requirements in Table C. The results of the four WET tests,which were
conducted in April, May,June &July 2020, have been attached with Table E.
Section 3.19:The four required WET tests were conducted in April, May,June &July 2020, and the
results have been attached with Table E.
Section 3.26:After consultation with NCDEQ Aquatic Toxicology Branch (ATB), Pittsboro was instructed
to begin second species testing ASAP and repeat for 3 consecutive months so that the required 4 test
results would be included with the NPDES Permit renewal application. Pittsboro completed this testing
in April, May, June &July 2020 and the official results have been attached as Table E.

Section 2.4: Process Flow Diagram Narrative
Because of the changes that are proposed to the Pittsboro WWTP,two flow diagrams have been
provided that show the two phases. Phase 1 will be the construction of the new Chatham Park Water
Recovery Center(CPWRC)and connection of this plant's effluent to the Pittsboro plant discharge Outfall
001. Phase 2 will be the conversion of the Pittsboro WWTP into a pump station that will pump raw
sewage to the Big Buffalo WWTP in Sanford.
A process flow diagram for the existing Pittsboro WWTP could not be located,so staff have diligently
dug through old files and added their experience to document the current plant operation.The exact
location of all existing piping could not be determined but the connections are accurate. For phase 1,
the plan set for the tie-in of the CPWRC to the Pittsboro WWTP has not yet been approved by the Town,
so only the most recent proposal has been shown.The CPWRC is under construction with permit
#WQC0039375 and the force main for the effluent discharge is also under construction with permit
#40514.The raw sewage force main is also under construction on this same permit#40514 but has been
shown on the Phase 2 diagram. It is intended to be operational for use if needed during start-up of the
CPWRC.After the new plant is operational,this line will not be used until Phase 2 is complete. For phase
2, plans for the pump station and the force main to Sanford have been submitted to DWI but not yet
approved,so only the most recent proposal has been shown.
Background
The Pittsboro Wastewater Treatment plant was originally constructed in 1977 and upgraded in 1988 and
2010. In 1988, an additional aeration basin, clarifier,filters, mechanical bar screen, and UV system were
added. In 2010, EQ storage basins and a new UV disinfection system was installed. In April of 2010 the
Town of Pittsboro began supplying the 3M Corporation reclaimed water for its manufacturing operation.
The WWTP design capacity is 0.75 mgd and the reclaimed water pump station is approximately 0.3 mgd.
Current Treatment Process
Wastewater enters the Pittsboro WWTP at the influent channel and large trash items are removed with
a mechanical bar screen. Wastewater then flows to the influent wet well and is pumped through a
Magnetic Flow meter and to either of the Aeration Basins or is diverted to the EQ pump station and
pumped to the EQ storage basins.The water enters two identical treatment trains for biological
treatment and clarification. The clarified water from both units is chemically treated for phosphorus,
flows to the sand filtration units, and then passes through UV disinfection. UV operation is controlled by
a signal from the Influent flow meter.The treated effluent is either discharged to Roberson Creek or
chlorine is added and it is pumped to the 3M Manufacturing Facility as reclaimed water.
Excess flow that gets diverted to the EQ basins for storage is returned to the influent pump station to
begin treatment, usually overnight. The reject water from the sand filters and the sludge thickener is
also returned to the influent pump station. However, it should be noted that this water passes through
the influent flow meter again and the EQ basin storage water does not.
The plant operates at a controlled flow from 230—521 gpm. (maximum plant design flow is 521 gpm)
When the EQ storage basins are full,the plant is operated in level mode with flow of 521-1250 gpm
split between the two basins.When the plant is switched into level mode, air is shut down on the exit
side of each aeration basin,with air remaining on the influent side for treatment.The sand filters are

bypassed to prevent damage and the UV system is placed in manual mode and set to 100%for both
banks.
Biosolids Disposal
Biological solids are removed from the plant on a daily basis,treated with polymer,and thickened with a
rotary drum thickener. The solids are then land applied as fertilizer for animal feed crops. Land
Application permit#WQ0020019.
Phase 1-Chatham Park Water Recovery Center(CPWRC)
Construction is almost complete on the CPWRC.The 12"force main that will carry treated effluent from
the new CPWRC to the Pittsboro WWTP outfall is also under construction.The final plans for the
connection of this force main to the Pittsboro WWTP have not yet been completed, but the most recent
plan revision has been used to complete the process flow diagram.
The force main will drop into a small vault to dissipate the water velocity and the vault will connect
directly to the original (now abandoned) U.V.trough.This water will flow into the splitter well with the
Pittsboro effluent where the total combined flow can be sampled.Total flow can then be directed either
to the reclaimed water pump station or through the Parshall Flume. If sent to the reclaimed pump
station, it will be treated with chlorine before leaving the plant. Otherwise,total flow will be metered
through the flume before discharging into Roberson Creek. No modifications to the 16" discharge pipe
or the streambank have been proposed.
NOTE:the 12" raw sewage line from the CPWRC is under construction (permit#40514) and being
installed parallel to the treated effluent line from the CPWRC.This line will only be used if needed during
start-up of the CPWRC. If there are difficulties during start-up and the ORC does not want to discharge
to Roberson Creek,the effluent can be diverted into the raw sewage line and sent to the headworks of
the Pittsboro WWTP for treatment.After the new plant is operational,this line will not be used until
Phase 2 is complete.
Phase 2—Pittsboro Pump Station with Force Main to Big Buffalo WWTP
Construction plans are under review by DWI for the conversion of the Pittsboro WWTP into a pump
station that would send untreated effluent to the Big Buffalo WWTP in Sanford. While the final plans
have not yet been approved,the most recent plans have been used to complete the second process
flow diagram.
Both the Pittsboro WWTP&the CPWRC will operate together until the pump station and force main are
completed. Once the pump station is finished,aeration basins will be converted into additional EQ
storage.
All raw sewage currently flowing to the Pittsboro WWTP (up to 0.75 mgd) along with an additional 1.25
mgd of raw sewage from future Chatham Park development,will be pumped to Sanford.This will
remove Pittsboro's portion of the discharge from Outfall 001. Only 0.499 mgd of effluent from the
CPWRC would then discharge to Outfall 001.

Chatham Park
Decentralized Water Resource Recovery Facility (WRRF)
Preliminary Basis of Design Report
Revision 7: July 31, 2019
Introduction
This report is written to establish the Basis of Design for the construction of the
Chatham Park Decentralized Water Resource Recovery Facility(WRRF)to serve the
initial stages of development at Chatham Park North Village.The initial design capacity
of the WRRF is 500,000 GPD(consisting of two parallel 125,000 GPD treatment trains
and one 250,000 GPD treatment train)with proposed future expandability up to 1.0
MGD ADF(by adding an additional 2 parallel 250,000 GPD treatment trains). The
WRRF facility will be a Membrane Bioreactor(MBR)system designed to primarily treat
for Biochemical Oxygen Demand(BOD),Total Nitrogen(TN)and Total Phosphorous
(TP).
The initial 0.5 MGD WRRF will be constructed in two(2)phases. Phase I will consist of
construction of a 0.25 MGD WRRF consisting of two initial 0.125 MGD parallel treatment
trains. Phase II will expand the facility to 0.5 MGD by the addition of a single 0.25 MGD
parallel treatment train. Equipment outlined in this document consists of equipment
installed as part of both Phase I and Phase II improvements. Phasing of equipment has
been included to document bringing the initial facility online with provisions of meeting
future loading conditions.
The plant will be designed to discharge effluent to the existing Town of Pittsboro Water
Reclamation Facility(WRF)discharge location at Robeson Creek(Outfall No. 1)via a
new effluent pump station and forcemain. In addition,the plant will be designed to
provide beneficial reuse quality effluent to meet future water reuse demands for water
supply sustainability.
1

The Town of Pittsboro,North Carolina has a current National Pollution Discharge
Elimination System(NPDES) permit(NC DEQ permit number NC0020354)for a
combined discharge of 3.22 MGD that allows for two discharge locations,Outfall No. 1
and No.2.
The NPDES permit is written with a combined Total Maximum Daily Limit(TMDL)on
both outfalls. The TMDL maximum load for TN is 36,202 lbs. per year and the
maximum load for TP is 4,551 lbs. per year. Outfall No. 1 has an additional requirement
limiting total phosphorous discharge to 322 lbs. during the summer period defined as
April 1 to October 31 of each calendar year. As a result,during these seven months of
the year,additional phosphorous will need to be removed by the treatment system.
The Town of Pittsboro has received a modification to their NPDES permit to increase the
discharge capacity to 1.249 MGD at Outfall No. 1.This reduces the capacity at Outfall
No.2 to 1.971 MGD.Although the permitted discharge flow capacity at Outfall No. 1 is
increased,the maximum 322 lbs.of TP allowed to be discharged from April 1 to October
31 of each calendar year will remain the same.Based on this, the approximate TMDLs
for Outfall No. 1 and Outfall No.2 are summarized in Table 1.

The TN and TP allocation for Outfall No. 1 into Robeson Creek will be divided between
the existing 0.75 MGD Town of Pittsboro WRF and the proposed 0.499 MGD
Decentralized WRRF.To maintain consistent effluent limits for the two plants the
approximate TN and TP allocations for each plant are summarized in Table 2.

Design Influent Characteristics
The proposed design influent wastewater characteristics for the Decentralized WRRF are
summarized in Table 3. The design is based on raw influent wastewater that is
biodegradable with no toxic compounds present. Additionally,influent Fats,Oils and
Grease(FOG)shall always be less than 100 mg/L.There shall also be approximately 120
mg/L of alkalinity available to avoid pH depressions. The influent Chemical Oxygen
Demand and Five-Day Biochemical Oxygen Demand(COD/BOD5)ratio shall be
between 1.7 and 2.3. Additionally,it is assumed that BOD and TN is not recalcitrant in
concentrations over the permit limits.

Effluent Limits for Reclaimed Water
The effluent limits in Table 4 meet the requirements for direct discharge of the effluent
from the Decentralized WRRF to Robeson Creek at the location of the Town of
Pittsboro's Outfall No. 1.As the North Village Development expands,the WRRF will
provide reclaimed water for reuse within the distribution system. This will decrease the
flow discharged from the Decentralized WRRF to Robeson Creek. Additional
disinfection will be required of the treated water in order to meet North Carolina Type 2
reclaimed water standards as defined by 15 NCAC 02U.0401. These design
requirements, which only apply to reclaim water(RCW)include the following:
1. Continuous online monitoring and recording for turbidity and flow
2. A control system to divert flow from the RCW system to Outfall No. 1 if either
the turbidity exceeds 10 NTU or permitted pathogen levels cannot be met.
3. Automatic standby power supply
4. Dual disinfection consisting of UV Disinfection and chlorination
5. The process shall provide for a combined disinfection capable of the following:
a. Log 6 or greater reduction of E.coli
b. Log 5 or greater reduction of Coliphage
c. Log 4 or greater reduction of Clostridium perfringens
6. Maximum pathogen counts depicted in Table 5

Table 5—Additional Type 2 RCW Maximum Pathogen Count
Parameter Monthly Average Daily Maximum
Coliphage <5/100 mL (geometric mean) <25/100 ml
Clostridium perfringens <5/100 mL (geometric mean) <25/100 ml
Project Equipment
The initial construction of the WRRF has been coordinated to allow operation of the
facility with a capacity of up to 0.5 MGD ADF as outlined in Phases I and II with
provisions on some structures to expand in the future to meet a buildout flow condition
of 1.0 MGD ADF. However,currently there is no loading to the collection system.
Loading will increase over time as development within the Chatham Park North Village
Development expands with initial flows to the WRRF quite low. To accommodate the
low flow startup conditions,jockey equipment is being installed on certain facilities at
the time of initial construction. Provisions have been made to replace jockey equipment
with full sized equipment as flow/loading rates increase at the facility with minimal
infrastructure modifications to meet redundancy requirements for Phase II. The
following jockey systems are being provided at this time:
1. Influent Jockey Pump—a single submersible jockey pump will be provided to
manage low turndown and startup flow conditions at the WRRF. All electrical
and mechanical facilities have been coordinated to allow for removal and
replacement with a full-sized pump as loading rates increase to the facility.
2. Aerobic Jockey Blower—a single jockey blower will be provided to manage low
loading conditions at the time of startup at the WRRF. All electrical and
mechanical facilities have been coordinated to allow for removal and
replacement with a full-sized blower as loading rates increase to the facility.
3. Effluent Pumps—a single submersible jockey pump will be provided to manage
low turndown and startup flow conditions at the WRRF. All electrical and
mechanical facilities have been coordinated to allow for removal and
replacement with a full-sized pump as loading rates increase to the facility.
4. RCW Pump—a single jockey pump will be provided to manage initial low RCW
demands and plant water demands during the initial startup phase of the WRRF
and expansion of the Chatham Park NPW distribution system/users. All
electrical and mechanical facilities have been coordinated to allow for removal
and replacement with a full-sized RCW pump as RCW demands increase at the
WRRF and within the Chatham Park RCW distribution system.

Headworks
The headworks system will be installed ahead of the influent pump station to provide
screening of the raw wastewater entering the plant. An influent three-way splitter box
with manually adjustable slide gates will split the influent flow to the screen channels.
Two(2)mechanical screens will be installed during the initial phase of the project to
meet Phase I and II requirements while the third screen will be installed in the future as
part of the 1.0 MGD facility buildout.The headworks screen channels will consist of
concrete channels each approximately 18 inches wide with the bottom of the screen
channel being approximately 16 feet below grade.
Screening prior to the biological treatment system is required to remove large solids,
rags, and particles larger than 2 mm size.The proposed headworks system includes two
(2) automatic fine screens each with a design capacity of 870 gpm(1.25 MGD). This will
provide 100%redundancy of the screening equipment for Phases I and II. Space will be
provided to install a third screen in the future to allow for a 3 x 50%redundancy for the
future 1.0 MGD ADF facility.
The screening equipment will be provided with a conveyor to remove solids off the
screens,a compactor to reduce solids volume, and dumpster for collection of solids.A
packaged odor control system will be installed on vents to provide odor control for the
headworks and influent pump station.Design for the headworks system is summarized
in Table 6.

InfluentPumpStation and Splitter Boxes
p
The influent pump station is designed to convey screened wastewater from the
headworks system by force main to a splitter box which will distribute flow to the MBR
trains. Initially the splitter box will include four(4)weir gates for flow splitting with
one (1)gate splitting flow for each 0.125 MGD train installed in Phase I and two(2) gates
splitting flow into the 0.25 MGD train installed in Phase II. Each gate will be 3 feet wide
and allow for even splitting of flow between all trains.
6

The proposed influent pump station consists of a precast concrete wetwell with lockable
aluminum access hatch. Three rail mounted submersible wastewater pumps,each with
Variable Frequency Drive(VFD)control,will be installed in the pump station. For
Phase I,two pumps will be 434 gpm each in capacity while the third pump will be a low
flow startup jockey pump as noted above. As flow increases after the startup of the
WRRF,the jockey pump will be removed and replaced with another 434 gpm pump to
meet redundancy requirements for the 0.5 MGD ADF WRRF. In the future,the existing
pumps will be replaced with three 868 gpm pumps to provide 3 x 50%redundancy for
conveyance of future peak flows as high as 2.5 MGD for the 1.0 MGD ADF facility.
Downstream from the pump station will be a precast concrete valve vault and meter
vault. This vault will include check valves,shut off valves,pressure gauges, and
interconnecting piping. Following the valve vault,a meter vault will house the
magnetic flow meter which will record trends in pump flow and totalize daily volume of
wastewater pumped. Above ground by the pump station a NEMA 4X control panel will
contain electrical components,VFDs,pump controls,and support for instrumentation.
Design parameters for the influent pump station are summarized in Table 7.

Membrane Bio Reactor (MBR) System
The basis of design for the biological treatment MBR System is a NEOSEP MBR system
provided by Kruger. The proposed MBR System is comprised of two(2)0.125 MGD
biological MBR treatment trains having a total average design capacity of 0.25 MGD for
Phase I and one(1)0.25 MGD biological MBR treatment train for a total treatment
capacity of 0.5 MGD ADF for Phase II. The peak hour flow capacity of the two MBR
trains in Phase I is 0.625 MGD and 1.25 MGD for all three trains in Phase II.
Each train is configured with one anaerobic reactor, one pre-anoxic reactor, one aerobic
reactor,and one post-anoxic reactor. Each train will discharge into a common
intermediate channel equipped with intermediate screening prior to flowing into two
membrane micro-filter tanks with one membrane unit in each tank.Air will be added in
the aerobic reactor for nitrification and BOD removal. Air scour will be added in each
membrane tank to enhance effluent dissolved oxygen and to reduce fouling of the
membranes. TN will be removed by biological denitrification which will occur in the
post-anoxic zone and by recycling flow from the aerobic zone to the pre-anoxic zone via
a nitrate recycle pump. BOD will be removed by conversion to CO2 gas and biomass
7

which will be removed as waste activated sludge(WAS). Total nitrogen will be
removed through the nitrification/denitrification process.
Phosphorus removal will be accomplished by luxury biological phosphorus uptake
initiated in the anaerobic selector zones and taken up in the pre-anoxic reactors.
Additional total phosphorus can be removed to meet the low TP limits indicated above
by chemical addition using alum,which will be added in proportion to flow to the
aerobic zones. Phosphorus either accumulated in the biomass or chemically precipitated
with aluminum will be separated from the effluent by the membranes and removed
from the system as waste activated sludge.
To prevent the decrease in alkalinity and resulting depression of pH due to nitrification,
sodium hydroxide will be fed to the pre-anoxic reactors.The sodium hydroxide feed
will be controlled via a pH analyzer in each aerobic reactor with dedicated control
loops/chemical feed pumps. Supplemental carbon will be provided to the inlet of the
Post-Anoxic Zones to assist with total nitrogen removal.
The anaerobic basins,pre-anoxic basins and post anoxic basins all contain 1.8 HP mixers
designed to keep solids suspended and the tanks well mixed. The aerobic reactors and
membrane tanks are mixed with fine bubble diffusers and coarse bubble diffusers,
respectively. The diffusers in the aerobic tanks are fed by a system of blowers located in
the mechanical building. The blowers consist of two(2)full sized blowers rated at 303
SCFM each to meet redundancy requirements and one(1)jockey blower package for
startup conditions during Phase I. The jockey blower will eventually be replaced with a
full-sized blower package to meet redundancy requirements of Phase II as indicated
above. The membrane tanks are aerated by a pair of blower packages rated for 924
SCFM each installed during Phase Ito provide for redundancy. Blowers are sized for
Phase II.
Once flow reaches the splitter box,wastewater will flow by gravity through the train
until it reaches the MBR Tanks. After leaving the treatment trains,the flow will pass
through intermediate screening to remove any large solids which can damage the
membranes. The intermediate screening will consist of a single mechanical screen rated
for 2,256 gpm for peak flows during Phase II. The mechanical screen will be equipped
with a screw conveyor and screw washer/compactor with a bagger system. A manual
bar screen will be provided for equipment redundancy.
As flow enters the membrane tanks it will either overflow into a RAS/WAS wetwell tank
or be pulled through the membranes as cleaned effluent for disinfection. Permeate
pumps will be required to draw water through the membranes and direct it to the
permeate tank before the flow continues to the disinfection process. Permeate pumps
8

are rated at 868 gpm each and are sized for Phase II with a shelf spare provided for
redundancy.
The membranes installed during Phase I will include two membrane tanks in parallel for
redundancy requirements. To meet redundancy requirements under Phase II flow
conditions, additional membrane modules will be added to the membrane system
installed in Phase I. The membranes themselves will require periodic cleaning which
will be done in place. This will be accomplished by reversing the permeated pumps and
drawing water from the permeate holding tank back through the membranes. Added to
the reversed flow will be sodium hypochlorite and/or citric acid as a membrane cleaning
agent.
Recycled Activated Sludge/Waste Activated Sludge (RAS/WAS)Pumps rated at 694
gpm each will draw solids from an overflow tank downstream of the membrane tanks.
Solids from the membrane overflow will be returned to the head of the MBR train at the
splitter box as RAS. Solids will be periodically removed from the MBR system as WAS
by a control valve which will direct flow from the RAS/WAS pumps to the sludge
holding tank. The sludge holding tank will be aerated to maintain aerobic conditions
and allow for reducing the volume of volatile solids.
Due to the location of the treatment facility, a packaged odor control system has been
included as part of the secondary treatment process to minimize odors at the WRRF.
The odor control system has been sized to provide odor control for equipment installed
in Phases I and II.
General design parameters for the MBR system are summarized in Tables 8 through 11.

Disinfection System
Once flow has passed through the membranes via the permeate pumps, flow will
be directed through a system of closed-vessel UV modules for disinfection. The
UV modules have been designed for a capacity of 0.625 MGD peak flow through
each bank. Two (2)banks will be installed to meet Phase I requirements with
one (1)bank serving as a redundant unit. During Phase II, an additional UV
bank will be added to meet peak disinfection requirements for Phase II with one
(1)bank out of service.
Table 12—UV Disinfection Equipment
Equipment Phase I Phase II
UV Banks 2 1
Flow which is directed to the RCW storage tank will receive dual disinfection via
chlorination. Liquid chlorine will be injected into the RCW downstream of the
UV system to meet residual requirements. The RCW tank has been designed to
achieve minimum contact time requirements for Type 2 RCW.
Effluent Pump Station
Flow which will not be sent to the RCW storage tank will be directed to an effluent
pump station. The effluent pump station is designed to convey treated effluent through
a force main to Outf all No.1 for discharge or redistribution as reclaimed water to 3M via
the RCW distribution system at the Pittsboro WRF.The proposed effluent pump station
consists of a precast concrete wet well with lockable aluminum access hatch and three
rail mounted submersible wastewater pumps with VFD control. Initially two effluent
pumps rated for 434 gpm and an effluent jockey pump will be provided.
Downstream from the pump station will be a precast concrete valve vault and meter
vault. This vault will include check valves,shut off valves, pressure gauges, and
interconnecting piping. Following the valve vault, a meter vault will house the
magnetic flow meter which will record trends in pump flow and totalize daily volume of
treated wastewater pumped. Above ground by the pump station a NEMA 4X control
panel will contain electrical components,VFDs,pump controls, and support for
instrumentation. Design parameters for the effluent pump station are summarized in
Table 13.

Reclaimed Water (RCW) Storage and Pump Station
Effluent from the system which is not pumped to Outfall No. 1 will be sent to the
Reclaimed Water(RCW)Storage tank. With the addition of sodium hypochlorite to
provide dual disinfection,the effluent from the MBR system is acceptable for reuse in
many applications including heating and cooling system make-up water,toilet flush
water,irrigation and many industrial and commercial applications.In addition,the
RCW system is designed to meet the needs for general wash down water,screen system
spray washers and site irrigation at the WRRF.
The RCW Storage Tank will provide approximately 100,000 gallons of storage in the
form of an above ground,round storage tank. The RCW Storage tank will provide
contact time for chlorination in order to obtain the necessary disinfection contact time to
achieve Type 2 reclaim water standards. Pumps will draw from the RCW Storage tank
to pressurize the plant non-potable system and deliver water to the RCW distribution
system. Two(2)434 gpm pumps and one(1)jockey RCW pump will provide for Phase I
and Phase II.

Downstream from each pump will be check valves and shut off valves. The combined
discharge header will include a pressure indicating transmitter and control valves for
the RCW distribution system or to return the flow back to the RCW tank if discharge to
the RCW distribution system is low.
Most users of the RCW distribution system will not have alternate means,nor will they
have controls,to operate in the event that RCW is not available. Therefore,in the event
the WRRF cannot fill the RCW tank,a potable fill line has been provided with an air gap
to supplement these water users.
12

Provisions have been made to allow for upsizing the RCW pumps in the future as the
demand for RCW increases within the RCW distribution system.
Waste Activated Sludge (WAS)Holding Tank
The sludge holding tank has been designed to meet the required capacity to hold the
sludge generated from the 0.5 MGD WRRF commissioned under Phase II. A second
sludge holding tank will be constructed in the future to accommodate the additional
sludge generated at build out by the 1.0 MGD WRRF. Each WAS holding tank will
include two positive displacement blower packages and coarse bubble diffusers. A
sludge pump will transfer solids from the sludge holding tank to a truck loading station
to be taken offsite for additional treatment/disposal.
The WAS holding tanks are sized to provide approximately 30 days sludge storage
capacity at 0.5 MGD of average plant flow with one tank and 1.0 MGD of average plant
flow with two tanks.
Duplex positive displacement(PD)blowers rated at 550 SCFM each and coarse bubble
diffusers will be provided for aeration to maintain DO concentrations in the tanks and
keep the tanks well mixed.Decanters will be provided to remove supernatant water
above the solids which will be return to the influent pump station for treatment.
Trucks will be used for removing solids from the WAS holding tanks. A truck loading
station,including a curbed area for spill containment,will be provided at the WAS
holding tank. A positive displacement solids pump rated at 250 gpm will pull solids
from the WAS holding tank and convey to a truck for transport. This will allow solids to
be hauled by a licensed contractor to an approved location for sludge
treatment/disposal.
To minimize odors at the WAS holding tank,the tank has been equipped with a
packaged odor control system.Design of the WAS holding tank system is summarized
in Table 15.

Chemical Feed Systems
The MBR system is designed to provide effluent TN concentrations less than 3.69 mg/L
and TP concentrations less than 0.145 mg/L as shown in Table 4 above. To achieve the
require low effluent TN and TP limits, chemical addition will be required. In addition,
chemical addition will be required to maintain a disinfection residual in the generated
ROW and also to provide for chemical cleaning of the membranes installed as part of the
MBR process.
Each system requiring bulk chemical feed tanks will include sufficient volume to receive
a full 4,000-gallon truck of chemical assuming that 15 days'worth of chemical remain in
the chemical storage tank. If the chemical being stored degrades or is substantially less
than a full truck load,the tanks may be sized to receive half truckloads of chemicals
while still holding 15 days'worth of chemical. Totes and barrels will be used in
applications where smaller volumes of chemicals will be required. The totes and barrels
will be located and sized so that a full tote or barrel can be placed next to the barrel or
tote currently in use. Tanks and piping will be heated and insulated to the design
requirements of the chemicals being contained. Totes or barrels will receive heat
blankets to prevent freezing and protect from precipitation when required.
All chemicals will be stored in a concrete containment area designed to contain 110%of
the largest storage tank capacity with 6 inches of freeboard to accommodate any rainfall.
Containment areas will be specific for each chemical being stored to prevent any
potential contact and reactions of chemicals should a leak occur.
The operating pH of the bioreactors must be maintained at greater than a pH of 7.2 to
avoid inhibiting the nitrification reaction rate.Also,the nitrification process consumes
about 7.14 mg/L of alkalinity as CaCO3 for each 1.0 mg/L of ammonia nitrified.
Therefore, alkalinity addition with sodium hydroxide will be provided to optimize the
nitrification process. Two(2)peristaltic chemical feed pumps will feed NaOH to the
influent channel ahead of the MBR process during Phase I to meet redundancy
requirements. An additional chemical feed pump will be added in Phase II to meet
chemical dosing demands. The feed rate of sodium hydroxide will be controlled based
on a pH analyzer in the aerobic zones in each train. The design of the sodium hydroxide
feed system is summarized in Table 16.
Table 16—Sodium Hydroxide Chemical Feed System Equipment
Equipment Phase I Phase II
NaOH Feed Pumps 2 1

The denitrification process is an anoxic biological process that reduces the nitrate
produced in the aerobic biological process to nitrogen gas.To optimize the
denitrification process it will be required to provide a supplemental carbon feed system
consisting of dedicated peristaltic chemical feed pumps with a single pump feeding to
the post-anoxic zones of each treatment train as residual BOD is likely not sufficient to
allow for complete denitrification. During Phase I,three(3)chemical feed pumps will
be provided to feed each train with one serving as a spare. In Phase II, an additional
chemical feed pump will be added to feed the 0.25 MGD train. The carbon feed system
will provide additional BOD to supplement biological metabolic processes and allow
nitrate to be effectively reduced to nitrogen gas to meet effluent TN limits. In addition,
the redundant peristaltic chemical feed pump will be set up during low-loading, startup
conditions to feed carbon into the inlet splitter box as a seeding source for startup.The
carbon source chemical feed will be flow paced based on the flow into the reactors and
the measured residual nitrate coming out of the aerobic zone. The design of the carbon
feed system is summarized in Table 17.
Table 17—Supplemental Carbon Chemical Feed System Equipment
Equipment Phase I Phase II
Carbon Feed Pumps 3 1
The primary means for reduction of total phosphorus is luxury biological uptake.
However,to meet the proposed effluent limits indicated above,additional phosphorus
removal will be required through chemical precipitation using alum and filtration with
the MBR membrane system. The alum feed system will be flow paced based on flow
into the treatment trains. In Phase I,two(2)chemical feed pumps will be provided to
feed to the aerobic zones of each treatment train;one(1)chemical feed pump will be
provided to feed to the supernatant flow coming off of the WAS holding tank which can
be a significant source of TP;and one(1)pump will be provided to serve as a redundant
pump for a total of four(4)chemical feed pumps. In Phase II, an additional chemical
feed pump will be added to feed the aerobic zone in the third train. The design of the
alum feed system for precipitation of phosphorus is summarized in Table 18.
Table 18—Alum Chemical Feed System Equipment
Equipment Phase I Phase II
Alum Feed Pumps 4 1
To meet the requirements for Type 2 Reclaimed Water, the effluent must be provided
with dual disinfection,which will include UV disinfection and chlorination to provide a
residual.The sodium hypochlorite feed system will include two(2)peristaltic chemical
feed pumps with one(1)pump serving as a redundant unit for feeding the RCW
discharge. These pumps will be flow paced based on flow into the RCW Storage Tank.

The UV Dose will be adjusted using a quartz sleeve fouling
factor of 0. 8 when sizing the UV system in order to
compensate for attenuation of the minimum dose due to sleeve
fouling during operation. The use of a higher quartz sleeve
fouling factor will be considered only upon review and
approval of independently verified data that
collected and analysed in accordance with protocols described
in NWRI Ultraviolet Disinfection Guidelines for. Drinking
water and Water Reuse (May 2003) .

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
J The reported value is between the laboratory method detection limit(MDL)and the laboratory method
reporting limit(MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument.This value is considered an estimate.
MRL Method Reporting Limit.The MRL is roughly equivalent to the practical quantitation limit(PQL)and is
based on the low point of the calibration curve,when applicable,sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.
N The analysis indicates the presence of an analyte for which there is presumptive evidence(85%or greater
confidence)to make a"tentative identification".
P Greater than 25%concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
[CALC] Calculated analyte-MDL/MRL reported to the highest reporting limit of the component analyses.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based
on acceptable LCS recovery.
QM-12 Precision between duplicate samples was outside acceptance limits.

discharge to Robeson Creek or for chlorination and distribution as reclaimed water by the Town,
and to provide reclaimed water from the Facility to Town customers(together, the"Services").
NOW, THEREFORE, for and in consideration of the mutual covenants and conditions
set out herein,the Parties agree as follows:
1. Commitment to Complete Construction of the Facility. Subject to the terms of
this Agreement, CPI agrees to take all steps reasonably necessary to complete construction of the
Facility and commissioning for operation. The target date for completion of construction is
December,2020; however, failure to complete construction of the Facility by the target date shall

(through the issuance of vouchers by CPI as provided herein) that has not commenced treatment
in the Facility is "obligated flow not yet tributary to the Facility". Except as otherwise agreed by
the Parties,prior to directing any wastewater flow from the Facility Service Area to any wastewater
treatment facility other than the Facility, excluding wastewater flow allocated by the Town in the
Facility Service Area before the Effective Date of this Agreement, and wastewater flow which is
otherwise directed after the Effective Date of this Agreement due to technical issues, the Town
shall direct and deliver wastewater flow generated from the Facility Service Area to the Facility
until such time as the actual flow plus the obligated flow not yet tributary to the Facility is equal
to 499,000 GPD.Thereafter,the Town may direct wastewater flows to other wastewater treatment
facilities. The total of actual flow plus obligated flow not yet tributary to the Facility shall not
exceed 499,000 GPD unless this Agreement is amended.
All vouchers issued by CPI for wastewater treatment capacity in the Facility shall be issued
at the flow rates approved by the North Carolina Department of Environmental Quality or other
applicable department,division,branch,or agency of the State of North Carolina("DEQ")in effect
at the time the voucher is issued. CPI may request DEQ approval of flow rate reductions from time

Master Services Agreement
CPI-Town of Pittsboro

to time as determined by CPI. Each DEQ approved flow rate reduction is applicable to obligated
flow not yet tributary to the Facility as of the approval date of the flow reduction.
The Parties shall cooperate in efforts to obtain flow reductions from DEQ for wastewater
treated or to be treated at the Facility and in the Town's efforts to obtain flow reductions from DEQ
for wastewater treated or to be treated at the Town WWTP or with respect to wastewater sent by
the Town for treatment by the City of Sanford, North Carolina, it being contemplated that CPI's
cooperation with Town flow reduction requests will be to furnish data regarding wastewater
treatment at the Facility. CPI shall furnish the Town with copies of all DEQ-approved flow
reductions issued to CPI.

that it will not charge persons in the Facility Service Area whose wastewater is treated at the
Facility any wastewater system development fees, as defined by the North Carolina General
Statutes("N.C.G.S.". or the equivalent of system development fees as defined by Town ordinances
or resolutions, whether denominated by the Town as "capacity fees", "impact fees", "Capital
Recovery Fees", "Access Fees", or other name, for the costs of capital improvements to provide
wastewater treatment at the Facility. Provided, however, and notwithstanding the foregoing, the
Town may charge persons in the Facility Service Area whose wastewater is treated at the Facility
its fees for wastewater treatment services currently known in the Town as "Connection Fees" and
"Meter Fee", together with charges at the user rates billed by the Town for wastewater collection
and treatment as provided herein.
Town shall provide customer service and CPI shall have no customer service-obligations
with respect to the Services. Town shall bill its customers for the Services provided by CPI and
pay CPI for the Services in accordance with Exhibit B attached hereto and incorporated by

6. Maintenance of Facility. As between the Parties, CPI shall be responsible for
maintenance and repair the Facility so that it functions as intended, in as economical a manner
with respect to operating expenses as reasonably practicable, and in compliance with current
industry practice and all legal requirements. Provided, CPI may allocate the responsibility for
operation, maintenance, and repair of the Facility to the Operator, but CPI also shall remain
responsible for such operation, maintenance, and repair under this Agreement. All operation,
maintenance and repair of the Facility shall be done in compliance with all legal requirements.
7. Town NPDES Permit. The Parties acknowledge that the Town currently holds a
National Pollutant Discharge Elimination System ("NPDES") permit, NPDES Permit No.
NC0020354 (the "Permit"), which authorizes the discharge of up to 1,249,000 GPD of treated
wastewater to Robeson Creek. With respect to the Permit,Town and CPI will cooperate to obtain
from DEQ, as soon as reasonably possible, such approval or authorization, including, without
limitation, renewal and modification of the Permit, as required by DEQ to allow up to 499,000
GPD of treated wastewater from the Facility to be discharged into Robeson Creek or to its
replacement discharge point(the"Approval"),and to take all actions required by DEQ to effectuate
the Approval. The Parties acknowledge that it may be necessary for them to submit applications
to DEQ for the Approval as co-applicants and that the renewed or modified permit may be issued
by DEQ to both Parties as permittees. Provided, however, notwithstanding any submittal of
applications to DEQ for the Approval as co-applicants,or any issuance of the Permit to both Parties
as permittees,the Permit at all times shall be owned and controlled by the Town.
As additional consideration for use of the Town's NPDES Permit for discharge of
wastewater treated at the Facility, CPI agrees to pay the Town the total amount of Twenty-Five
Thousand and 00/100 Dollars ($25,000.00), such payment to be made within ten (10) days after
commencement of operation of the Facility. Town agrees that the$25,000.00 will be set aside by
the Town to be spent on repairs or other improvements to reduce inflow and infiltration into the
Town's wastewater conveyance system.
The Parties acknowledge that if the Permit for the Approval is issued to the Parties as co-
permittees, that DEQ will consider the Parties to be jointly liable for all violations of the Permit

Master Services Agreement
CPI-Town of Pittsboro
Page 6
and that DEQ, in accordance with applicable DEQ regulations and other legal requirements,may
assess and collect fines (which word includes fines or penalties for violations, as they may be
referred to in applicable DEQ regulations) for violations of the Permit or take such other action for
violations against either or both Parties. Each Party, upon receipt of a notice of a violation of the
Permit resulting from actions or inactions of such Party or such Party's employees, agents,or,with
respect to CPI, actions or inactions of the licensed operator of the Facility,shall take action as soon
as reasonably practicable to remedy such violation, including payment of any applicable fine. A
non-violating Party who receives notice of a violation of the Permit resulting from the actions or
inactions of the violating Party or the employees,agents,or Facility operator of the violating Party
shall notify the violating Party of the notice of violation as soon as reasonably practicable after its
receipt of the notice. If a non-violating Party is required by DEQ to remedy a violation or pay an
applicable fine, or if a non-violating Party reasonably believes that it is necessary for it to remedy
a violation or pay an applicable tine in order to satisfy DEQ requirements, the violating Party shall
reimburse the non-violating party for the eosis of effecting the remedy. including the amount of
any applicable tine paid by the non-violating Party. Reimbursement by the violating Party shall he
paid to the non-violating Party within thirty (30) days following receipt from the non-violating
party of documentary evidence of the costs of effecting the remedy of the violation, including
payment of any applicable fine.
Town, at its sole expense, shall have the right to collect and analyze wastewater samples
at the point of demarcation from the Facility to determine compliance with the Permit and to
determine causes of non-compliance. To the extent that either Party is required to submit
compliance reports to DEQ or any other regulating authority regarding performance of the Facility,
the submitting Party shall provide the other Party with contemporaneous copies thereof. If joint
reporting is required under the Permit, the Parties shall cooperate and provide the reports in a
timely fashion.
In the event that the Town, in the Town's sole discretion, decides that it no longer desires
to maintain ownership of the Permit, to renew the Permit, or to retain rights to discharge
wastewater via the Permit, the Town shall offer to transfer the Permit to CPI prior to any action

Master Services Agreement
CPI-Town of Pittsboro
Page 7
which would limit or otherwise prohibit CPI's ability to discharge up to 499,000 GPD of
wastewater from the Facility. The Parties acknowledge that no transfer or attempted transfer of
the Permit by the Town to CPI is valid without the prior approval of DEQ.
8. Term. This Agreement is effective as of the date of execution hereof and shall
remain in full force and effect for a period of forty (40) years ("Initial Term") unless earlier
terminated as provided in this Agreement or by the agreement of the Parties. This Agreement will
be automatically renewed for additional ten (10) year periods (each, a "Successor Term")unless
terminated by written notice provided not later than one(1)year prior to the end of the Initial Term
or any applicable Successor Term. Upon the expiration of the Initial Term or applicable Successor
term hereof, Town agrees to pay CPI any balance owed CPI provided for in Exhibit B. Any new
operator of the Facility after the end of the Term shall be an operator who is properly licensed.
9. Default and Termination for Default. If an order for relief is entered against a
Party in any bankruptcy proceeding, or if a Party makes a general assignment for the benefit of
creditors, or if a receiver is appointed for all or a portion of a Party's property, or if a Party
otherwise defaults in the performance of its material obligations under this Agreement, then the
non-defaulting Party may,upon notice and the defaulting Party's failure to cure such default within
thirty (30) days after the non-defaulting Party receives notice, terminate the Agreement without
prejudice to any other right or remedy the non-defaulting Party may have. Notwithstanding the
foregoing, no default shall be deemed to have occurred hereunder with respect to the actions or
inaction of a Party during the pendency of a good faith dispute as to the compliance of those actions
or inaction with that Party's obligations hereunder; provided, however, that if such dispute
concerns the payment of money owed (or allegedly owed) by one Party to the other, the amount
in dispute shall be deposited in an escrow account with a national or state chartered banking

Final Agreement. The Interim Agreement also provided that if the Final Agreement is not
executed,all design,engineering, and permitting documents shall be the sole property of CPI. CPI
and ONSWC have not agreed on a Final Agreement and CPI does not intend to enter into a Final
Agreement with ONSWC.
It is the understanding of the Parties that it was ONSWC's intent to assign its interest in
the Prior MS Att'eaf ent tti ;("litham Park Reclaimed Water Company, LLC ("CPRWC").
ONSWC has not notified the Town of the consummation of any such assignment,but the Town's
renewal applicatitiiff4Srrt6 Pit:was submitted to DEQ with the Town and CPRWC as the co-
applicants.

WITNESSETH:
WHEREAS, Pittsboro owns and operates a wastewater collection and treatment system

Carolina. Sanford further agrees to reserve 2.0 MGD of wastewater treatment capacity in its
Water Reclamation Facility for Pittsboro.
II. Pittsboro agrees to pay for treatment of all wastewater delivered to Sanford at the
specified point of delivery pursuant to this Contract in accordance with the applicable charges as
set forth herein. Additionally, Pittsboro shall pay a charge for the reserved wastewater treatment
capacity in Sanford's Water Reclamation Facility in accordance with this Contract. Pittsboro
further agrees and commits to deliver to Sanford all of its wastewater, saving and excepting any
flow up to 0.5 MGD delivered to the Pittsboro-Chatham Park Reclamation facility, up to the 2.0
MGD of capacity reserved herein.

III. Both parties agree as follows:
A. Term. Unless sooner terminated by mutual agreement or as set forth herein, the
term of this Agreement shall be 30 years from the Effective Date of this Agreement. This
Agreement may be renewed for two (2) additional thirty (30) year terms. Both parties agree
that the provision of wastewater treatment is vital to Pittsboro and the significant usage is vital
to Sanford, thus, termination will not be entered into lightly and both parties agree to make
every effort to promptly notify the other of its intent regarding this service.
B. Design, Permitting, Construction of Facilities and Point of Delivery. Pittsboro, at
its expense and at no cost to Sanford, will design, permit, and construct a force main
transmission line running along US Highway 15-501 from Pittsboro to the Sanford wastewater
system, a lift station, and a collection system with adequate grit removal and odor control

Point of Delivery, which approval shall not be unreasonably withheld. Pittsboro shall own,
operate, and maintain the Interconnection Infrastructure to the Point of Delivery.
C. Pretreatment Program.
(1) Pittsboro shall establish and conduct an industrial pre-treatment program
in accordance with Sanford's rules and regulations, to ensure that wastewater received from
Pittsboro meets the standards set in Sanford's Sewer Use Ordinance. Pittsboro shall adopt
necessary ordinances, policies and programs to operate a consistent pre-treatment program.
(2) Pittsboro shall collect and supply Sanford with all necessary information
for prior approval by Sanford of all required pre-treatment permits and thereafter to verify
compliance by industrial permit holders.
(3) Prior to Pittsboro issuing any pre-treatment permits, it shall submit

2

(6) Sanford shall have the right to audit Pittsboro's pre-treatment program at
any time upon written notification and Pittsboro shall supply all information necessary for the
audit.
D. Exceeding Reserved Capacity. Pittsboro agrees that it will not transmit
wastewater to Sanford on an average monthly/daily flow basis in excess of its wastewater
treatment capacity reserved in this agreement. To incentivize additional reservation of capacity
or reduction in flow, if the monthly average flow received by Sanford from Pittsboro exceeds the
reserved capacity of 2.0 MGD for two consecutive months the third month and any additional
month's overage within the following 12-month period shall result in an "excess treatment
charge" of 125% of the established charge for treatment. If the daily average flow received by
Sanford exceeds the reserved capacity of 2.0 MGD in any month by more than 2.0 MGD, then
the additional flow in excess of 2.0 MGD will be charged at an excess treatment charge of 125%
of the established charge for treatment. If either condition occurs during the term of this
Contract, Pittsboro shall pay the additional excess treatment charges upon billing by Sanford. In
addition, Pittsboro shall, if requested by Sanford, provide a plan for addressing the excess flow
which may include reducing the flow, reservation of additional capacity and renegotiation of
capacity charge.
In the event Sanford provides to Pittsboro reuse water pursuant to a separate
agreement, Pittsboro may deliver an equal amount of wastewater to Sanford with no additional
Capacity Charge. Furthermore, the excess treatment charges listed above shall apply only to the
excess flows which exceed the total of the reserved capacity plus the reuse water volume
provided to Pittsboro.
E. Improvements or Future Capacity.
(1) Improvements and upgrades required and/or necessary for the efficient
and cost effective operation of the Sanford Water Reclamation Facility applicable to the
treatment of each gallon processed at the Facility shall be shared by Sanford and Pittsboro.
Pittsboro's share of the cost thereof shall be in the same proportion as its share of the total
treatment capacity of the Sanford facility. That share shall be an additional Capacity Charge paid
in installments over a term of not more than 25 years.
(2) If Sanford decides to make elective improvements to the Water
Reclamation Facility which are not necessary or required, Pittsboro has the option to participate
in the cost.
(3) If Pittsboro requests Sanford to make an improvement to the Facility that
is not necessary or required, then Sanford will evaluate and decide whether to make the
improvement and whether to participate in a portion of the cost. Sanford reserves the right to
decline to make said requested improvement.
3

(4) If Pittsboro requests an improvement that Sanford allows, but declines to
participate in, any associated expenses shall be paid by Pittsboro upon terms negotiated prior to
the improvement.
F. Charges.

shall, on a monthly basis, charge according to Sanford's utility customer policies, and Pittsboro
shall pay a "Wastewater Treatment Charge" determined in accordance with Exhibit B. The
Treatment Charge shall be calculated annually. To determine the Treatment Charge using prior
year actuals, Sanford will notify Pittsboro by January 2, or as soon thereafter as possible, of the
updated Treatment Charge to be effective July 1 through June 30 of the following municipal
fiscal year. Upon request by Pittsboro, Sanford will provide a projection of the charges, to assist
with budgeting or otherwise.
(2) For the reservation of 2.0 MGD of wastewater treatment capacity in the
Water Reclamation Facility Pittsboro shall pay to Sanford a "Capacity Charge" determined in
accordance with Exhibit C.
G. Meter. Charges for all treatment services furnished under this Contract by
Sanford shall be based upon the volume of wastewater delivered at the Meter. At the Point of
Delivery, or some other location approved by Sanford, Pittsboro shall furnish and install, at the
expense of Pittsboro, the necessary metering equipment and required devices, as approved by
Sanford, (the "Meter") for properly measuring the quantity of wastewater delivered to Sanford.
Pittsboro shall calibrate the metering equipment at least once every three years. Sanford may
request it to be calibrated more often. If requested more than once every three years, Pittsboro
shall test the metering equipment to see if it registers 3% above or below the test flow. If so,
Pittsboro shall pay for the test and shall calibrate the equipment. If the test reveals that the meter
is registering accurately (within 3% above or below) Sanford shall pay for the testing. If
Pittsboro initiates a test, Pittsboro shall inform Sanford prior to testing and pay for the test,
inform Sanford of the results and if needed, calibrate the equipment. Charges for all treatment
services furnished under this Contract by Sanford shall be based upon the volume of wastewater
delivered at the Meter. In the event of any discrepancy resulting from an inaccurate meter, the
charges shall be adjusted equitably.
H. Meter Readings. At its expense, Pittsboro agrees to transmit meter readings to
Sanford via automatic meter reading technology compatible with Sanford's meter reading and
billing capabilities. A report of the daily volumes along with a log of pump run times, recording
charts, calibrations and adjustments, may be provided upon request. Sanford, at all reasonable
times,shall have access to the meter for the purpose of verification of readings.
I. Meter Failure. If the Meter fails to register for a period of fourteen (14) or fewer
days , the amount of wastewater furnished during such a period shall be deemed to be the amount
of wastewater delivered in the corresponding period immediately prior to the failure. If the Meter
fails to register for a period greater than 14 calendar days, the amount of wastewater furnished
after the initial 14-day period shall be billed an amount for a volume equal to the rated capacity
4

of the wastewater pump(s), multiplied by the total time pumped. If the replacement of the meter
is deemed necessary by Sanford, Pittsboro shall replace the Meter at its expense.
J. Failure of Service. Sanford shall operate and maintain its wastewater treatment
system in an efficient manner consistent with law and regulation and will furnish Pittsboro with
the maximum capabilities as stated herein. Temporary or partial failures to receive wastewater
shall be remedied with all possible dispatch but shall not constitute a breach so long as such
remedy is diligently being pursued.
K. Force Majeure. A "Force Majeure" is defined as any event arising from causes
beyond the reasonable control of Sanford, including but not limited to fire, flood, acts of God,
terrorism, war, natural disaster, tornado, hurricane, civil strikes or labor disputes, riots, system
failure, broken pipes, or other actions causing an inability to serve beyond the reasonable control
of Sanford. It shall not be considered an event of Default hereunder and Sanford shall not be
responsible for an inability to perform or any delays, damages, costs, expenses, liabilities or
other consequences that may arise as a result of Force Majeure. It shall not be considered a an
event of Default hereunder and Pittsboro shall not be responsible for an inability to perform or
any delays, damages, costs, expenses, liabilities or other consequences that may arise as a result

WASTEWATER TREATMENT CHARGES
Calculation of the Annual Treatment Charge:
1. Sanford will use its certified financial audit to determine the net total operating
cost ("TC") of for each fiscal year as follows.
2. The net total operating cost ("TC") will be determined by taking the total
operating expenses of the Water Reclamation Facility less any expenses associated with
operating the pretreatment program (except those applicable to Pittsboro) along with any non-
treatment related capital expenses ( i.e. vehicle replacement expenses.)
TC =total operating expenses— [pretreatment costs (except those applicable to Pittsboro)
+non-treatment related capital expenses]
3. The net total operating cost ("TC") as determined above shall be divided by the
wastewater flow ("TF") treated at the Sanford Water Reclamation Facility for the previous year
to determine a Wastewater Treatment Charge Unit Cost per gallon of wastewater treated ("UC").
4. ANNUAL WASTEWATER TREATMENT CHARGE UNIT COST
CALCULATION:
Unit Cost(UC) = (TC)_(TF)
