D. RATIONALE FOR LIMITATIONS:
As listed on the IUP Limits Page(s), PART I, Section F of the IUP.
RATIONALE#1:
Review of IU Monitoring Data, with no Over Allocation situation:
The following pollutants were assigned numerical limits in this IUP based
on a review of monitoring data for the permittee to determine what ranges of
concentrations are currently being discharged. To account for sample
variability a factor was applied to the monitoring data to determine the
permit limit. Permit limits assigned by the Local IUP Control Authority can
not result in an Over Allocation situation for any pollutants.

IUP Synopsis
RATIONALE #2a:
Categorical Industrial Limits, with no Over Allocation situation:
Check here if Combined Wastestream Formula (CWF) or other categorical
limits calculations were used. If used, Please attach calculations: (see CWF
Spreadsheet, Appendix 6-F)
Were used(attach calculations)
Were not used
The following pollutants were assigned numerical limits in this IUP based
on the categorical regulations. These limits do not result in over allocations.
RATIONALE#3a:
Over Allocation Prevention, with IU pollutant reduction:
The following pollutants were assigned numerical limits in this IUP based
on allocating the Maximum Allowable Industrial Loading (MAIL)
determined with the Headworks Analysis (HWA) among all Industrial
Users. The total loading of each pollutant from all permitted discharges
does not exceed the MAIL. These limits do not result on over allocations.
BOD, TSS, Ammonia,
RATIONALE #3b:
Interim Limits for IU pollutant reduction:
The following pollutants were assigned interim numerical limits in this IUP
to allow time for the industry to come compliance with final limits that will
not result in over allocations.

RATIONALE tt4:
4.) Other Rationale for Limitations:
The following rationale was used for developing IUP Limits.
Parameter Rationale
Oil and Grease Prevention of Inhibition or Passthrough
RATIONALE #5a:
Non-Categorical Parameters where No Limit needed or assigned in an IUP:
The following pollutants were not assigned numerical limits in this IUP
because the loadings for these pollutants from this IU were less than 5% of
the MAHL. The loading of these pollutants from this IU is considered
insignificant at this time.
Pollutant Avg SIU mg/1 T Avg SIU lbs/day 5% MAHL, lbs/day

ENGINEERING ALTERNATIVES ANALYSIS
FEBRUARY 2022
SECTION 1
GENERAL INFORMATION
1.1 INTRODUCTION
Harnett Regional Water (HRW) operates the North Regional Wastewater Treatment Plant
(WWTP). The facility was originally purchased from the Town of Lillington in 1999 as a 0.75
MGD facility. Since that time, the facility has been upgraded from the 0.75 MGD secondary
treatment facility to a 7.5 MGD tertiary treatment facility. The NPDES permit for 7.5 MGD was
initially issued on November 1, 2017, and expired July 31, 2021. A renewal application was
submitted in January 2021 for the NPDES permit.
The North Regional WWTP utilizes advanced wastewater treatment processes to treat the
wastewater to tertiary levels including denitrification via anoxic zones in the oxidation ditch for
biological nutrient removal. Recent upgrades at the WWTP included the installation of mixers
located in the oxidation ditch to increase the anoxic zone and the installation of stainless steel
mesh,disc filters to supplement the traveling bridge filters.The new disc filters have the capacity
to treat the plant design flow.
As a regional system, HRW has contracts with Fuquay-Varina,the Town of Lillington, and the
Town of Angier.A summary of the contractual arrangements,as well as the status of flows from
the HRW collection system is included in Section 2 of this document.
As growth has continued in this area of North Carolina, each of the contractual systems listed
above has made a request for additional capacity in the North treatment facility. With the
inclusion of the additional flow from the HRW collection system,the total capacity for the North
Regional WWTP is projected to increase from 7.5 MGD to 16.5 MGD.This document addresses
the proposed increase in capacity and evaluates alternatives for the additional capacity including
the possible expansion of the current NPDES permit.
1.2 NPDES DISCHARGE
The North Regional WWTP operates under NPDES Permit NC 0021636 with a discharge of 7.5
MGD. In June of 2021, a request was made to NCDEQ for speculative limits for two flows, 15
MGD and 20 MGD.At the time the request was made,the exact flow requirements for the facility
had not been determined. Speculative limits were received in October 2021 with limits provided
for the 15 MGD flow only. During the period from the request for speculative limits and the
receipt of speculative limits, the actual expansion requirements for the North facility were
determined. The flow increases were based on contractual relationships that will be described in
this document and additional capacity in the HRW collection system.The total flow requirement
based on the evaluation is 16.5 MGD.
MBD Consulting Engineers, P.A. (MBD) contacted NCDEQ in December 2021 and requested
that a speculative limits letter be issued based on a total flow of 16.5 MGD with the understanding
that the total seasonal poundage limits for Total Nitrogen(TN)and Total Phosphorus(TP)would
not be changed and concentrations limits may or may not have to be modified based on the
difference in the total discharge.

1.3 SERVICE AREA AND DESIGN FLOWS
HRW operates two wastewater treatment facilities in Harnett County,the South Regional WWTP
and the North Regional WWTP. The North Regional WWTP provides service for the northern
portions of the county,as well as areas in southern Wake County.This area of the state is subject
to an aggressive growth pattern, due in part to the influence of Wake County and the City of
Raleigh.
Section 2 of this document addresses the anticipated increase in flow into the North Regional
WWTP. The flow increases are based on requests from systems that own capacity in the North
Regional facility and an increase in the demand in the HRW collection system in the northern
portion of Harnett County.

SECTION 2
PROJECTIONS FOR POPULATION AND FLOW
2.1 GENERAL
In January of 2016 MBD prepared an Engineering Alternatives Analysis(EAA)for the expansion
of the Harnett North Regional WWTP to an NPDES discharge limit of 7.5 MGD. The expanded
NPDES Permit for 7.5 MGD was issued on November 1,2017.
Population and flow projections were provided as a part of the 2016 EAA. The population
numbers have been updated based on data provided through the NC Office of State Budget and
Management (OSBM) and are discussed below. The increase in population also impacts the
systems that own capacity in the North Regional WWTP.
The growth and subsequent need for expansion of the North Regional WWTP is discussed below.
2.2 REGIONAL PARTICIPATION AND MUNICIPAL CONTRACTS
HRW is strategically located in the Upper Cape Fear River Basin. HRW has the resources and
infrastructure to provide water and wastewater service to all of Harnett County and portions of
Wake, Lee, Cumberland, and Moore Counties. The regional water treatment plant provides
potable water to Lillington,Angier,Erwin,and Coats in Harnett County;Fort Bragg,Linden and
Spring Lake in Cumberland County; and Holly Springs and Fuquay-Varina in Wake County.
HRW also provides potable water to Johnston and Moore Counties.
HRW operates two wastewater treatment facilities, the South Regional WWTP, a 15 MGD
facility with an NPDES discharge into the Little River in the southern area of the county and the
North Regional WWTP,a 7.5 MGD facility with an NPDES discharge into the Cape Fear River.
Due to availability of natural resources and the strategic locations of the water treatment plant
and the two wastewater treatment plants, HRW is uniquely positioned to be a regional provider
of water and wastewater service to a large area of central North Carolina, an area that is
experiencing high growth rates, increasing the demand on these utilities.
HRW has contractual agreements with three municipal systems for treatment of wastewater at
the North Regional WWTP including Fuquay-Varina,Angier,and Lillington.Each of the entities
has participated in previous upgrades and all have the contractual ownership including the option
of requesting additional capacity. The North Regional WWTP began with the acquisition of the
existing Lillington WWTP and has expanded through growth in the HRW service area and
through agreements for capacity in the collection and treatment system from the municipal
partners.To address the need for wastewater treatment capacity,HRW constructed the 5.6 MGD
North Regional WWTP adjacent to the existing facility, and then expanded the facility to 7.5
MGD with the addition of flows from the Town of Erwin and the Swift Industrial WWTP. The
role and capacity of each of the participants in the system is discussed below.
In 1999,HRW purchased the existing Lillington WWTP from the Town.At that time,the facility
had a capacity of 0.75 MGD. Included with the treatment facility was the 52-acre site,providing
area for future expansions. In exchange for the WWTP and the 52-acre site, the Town of
Lillington received 1.2 MGD in capacity in the new WWTP and sewer revenue credits.

HARNETT REGIONAL WATER NORTH REGIONAL WWTP EXPANSION
ENGINEERING ALTERNATIVES ANALYSIS
FEBRUARY 2022
In 2000, Fuquay-Varina and Harnett County agreed to the joint construction of the
Harnett/Fuquay-Varina wastewater interceptor following Kenneth/Neills Creek to a new regional
5.6 MGD WWTP. At that time, Fuquay-Varina purchased 2.6 MGD of capacity in the new
wastewater treatment facility.
In 2006,the Town of Angier agreed to purchase 1.08 MGD of wastewater capacity in the plant
and 1 MGD of transmission capacity in the wastewater interceptor line. HRW and Angier also
agreed to jointly participate in the construction of a wastewater transmission line along
Chalybeate Springs Road.Angier extended the line to Highway 55,near the Wake County line.
All three participants have the contractual option to request additional capacity in the North
Regional WWTP. At this time, all three systems have made requests for additional flow.
2.3 POPULATION AND FLOW PROJECTIONS FOR HARNETT COUNTY
In January 2016, an EAA was prepared for the expansion of the NPDES permit from 5.6 MGD
to 7.5 MGD. The increase was based on the completion of the 20-inch force main that
interconnected the Town of Erwin and the Swift Industrial WWTPs to the North Regional
WWTP.
Detailed population projections were provided in the 2016 EAA for the upgrade of the facility
from 5.6 MGD to 7.5 MGD. Current populations projections have been compared to the
information that was provided in the 2016 report using primarily data from the OSBM.
The North Regional WWTP serves an area that borders to the south on the Upper Little River
and extends northward to the Wake County line. The northern area of Harnett County has
experienced the growth that is occurring in and around Wake County and is continuing to reach
out in all directions including to the south. The HRW capacity in the North Regional WWTP is
2.62 MGD.
According to the OSBM,Harnett County is listed as one of the counties with a population change
greater than 9.5%from April 1,2010,to July 1,2019.Wake and Mecklenburg counties accounted
for 38% of the total population increase in North Carolina over this same period. The actual
population increase listed on the OSBM website in Harnett County from April 1,2010,to April
1, 2020,was 16.4%.
Harnett County borders to the north side with Wake County and population growth in Harnett
County is influenced by the continued growth in this area of the state.All three of the contractual
systems are located either in Wake County or in the northern area of Harnett County, close to
Wake County.Due to the high growth rate in Wake County,the population in the northern portion
of Harnett County will continue to see population increases at a rate higher than most areas in
North Carolina.
The 2016 EAA included a discussion of available land for development in northern Harnett
County. The availability of water and sewer service in this area will drive the continued
development of available land. Population growth is expected to continue into the foreseeable
future. If the current growth rate of 16.4%over 10 years continues, in 2042(20-year period)the
population in Harnett County will increase by over 47,000. It is anticipated that the majority of
the growth will occur in planned communities that provide water and sewer service. Assuming
4

HARNETT REGIONAL WATER NORTH REGIONAL WWTP EXPANSION
ENGINEERING ALTERNATIVES ANALYSIS
FEBRUARY 2022
40% of the population growth will occur in the northern HRW service area, and a household
population of 2.3 per household, the number of services in the HRW service area alone could
increase by over 8,000.
2.4 ESTIMATION OF FLOWS
Northern Harnett County and the municipalities of Fuquay-Varina, Angier, and Lillington will
continue to grow in the next 20 years. In anticipation of this growth and to ensure adequate
wastewater treatment capacity to serve this growth, the three systems that own capacity in the
WWTP have requested additional capacity. HRW has also increased their projected capacity in
the WWTP to address the continued growth in sewer customers in the northern service area.
Table 2.1 below includes the current contract capacity for each of the partners in the North
Regional WWTP which accounts for the capacity in the existing 7.5 MGD WWTP. Table 2.1
also includes the current average daily usage and the committed flow that is not yet tributary to
the WWTP.The total of the current usage and the committed but not yet tributary accounts for a
total flow of 7.32 MGD of the 7.5 MGD permitted capacity.

Table 2.2 includes current contracted capacity in the North facility and the requested additional
allocation in the WWTP. The total current contractual capacity is 7.5 MGD and the four entities
foresee the need for an additional 9 MGD in capacity of the next 20 years. This would increase
the total capacity of the WWTP to 16.5 MGD.

SECTION 3
TECHNOLOGICAL ALTERNATIVES ANALYSIS
3.1 GENERAL
As a part of the EAA, HRW is required to evaluate Technologically Feasible Alternatives prior
to expanding the existing discharge. The disposal alternatives include:
• Connection to an existing WWTP(public or private),
• Land application including onsite subsurface,drip irrigation,or spray irrigation,
• Wastewater reuse,
• Surface discharge through the NPDES program,or
• Combination of the above.
One of the challenges for the North facility is the treatment requirements for the facility.As will
be discussed below,a study of the Cape Fear River is ongoing,and the speculative limits provided
do not increase the seasonal nutrient discharge (in pounds) allowed for the period from April 1
through October 31. The treatment requirements for the reduction of TN will approach the
treatment limits that can be achieved through advanced biological treatment.
3.2 TECHNOLOGICAL ALTERNATIVES
Listed below is an evaluation of the alternatives considered for the disposal of the additional flow
required to increase the discharge capacity of the North Regional WWTP from 7.5 MGD to 16.5
MGD or an increase in capacity of 9.0 MGD.
3.2.1 Connection to an Existing WWTP(Public or Private)
The North Regional WWTP was developed as the regional alternative for wastewater. In 1999,
HRW purchased the Lillington WWTP and upgraded the plant to its current treatment capacity
of 7.5 MGD.The North Regional WWTP has been successful in reducing or eliminating NPDES
discharges in this region.
As a part of the upgrades made by the participants in the system, substantial capital investments
have been performed to allow the flow to be piped to the North Regional WWTP.These projects
-V na Interceptor that extends from the Wake Count
y the Harnett/Fuquay an p line to a
regional pump station located on the north side of the Cape Fear River, which transfers the flow
across the river to the North Regional WWTP. A 24-inch force main was constructed along
Chalybeate Springs Road to connect into the Harnett/Fuquay-Varina Interceptor and a 24-inch
force main was extended from Angier north along Highway 55 to the county line. A 20-inch
force main was constructed from the Erwin and Swift Mills facilities to the North Regional
WWTP eliminating the discharge into the Cape Fear and providing another regional interconnect
with the North facility.
All of the untreated flow from the HRW collection system and the system participants enters the
headworks at the North Regional WWTP. The alternative of connecting to an existing WWTP
for treatment would require the construction of a new raw sewage pump station and force main
to transfer the untreated wastewater from the North Regional WWTP to another treatment plant
for treatment and disposal.
7

HARNETT REGIONAL WATER NORTH REGIONAL WWTP EXPANSION
ENGINEERING ALTERNATIVES ANALYSIS
FEBRUARY 2022
There are two systems downstream from the North Regional WWTP that have discharges into
the Cape Fear Basin:the HRW South Regional WWTP and the two City of Fayetteville WWTPs
(Cross Creek WWTP and Rockfish Creek WWTP). In order to transfer flow to either of these
facilities, an additional pipeline would need to be constructed and additional capacity would be
required in the treatment facilities.The closest plant and most likely facility to receive flow from
the North facility would be the HRW South Regional WWTP.
The South Regional WWTP is located on the Little River which runs along the southeastern
Harnett County line as it borders Cumberland County.The Little River connects to the Cape Fear
along this southern boundary.
The South Regional WWTP is a 15 MGD facility that serves southern Harnett County along the
border with Cumberland County and also provides wastewater treatment for Fort Bragg. The 15
MGD capacity is committed to existing systems including 10 MGD dedicated to Fort Bragg.Any
additional flow would require an expansion of the NPDES permit and a capital expansion of the
WWTP. HRW has not contacted DEQ regarding the possibility of expanding the NPDES permit
beyond 15 MGD at this time.
The capital expenditure to extend a force main (or gravity outfall) from the North Regional
facility to the South Regional facility and the cost to upgrade the South Regional facility is
included in the economic evaluations.
There are no other acceptable alternatives for the connection of the North Regional WWTP to
another regional WWTP that could accept the flow.
g p
3.2.2 Land Application
The option of Land Application was evaluated during the 2016 EAA for the upgrade to 7.5 MGD
and is also addressed below.
HRW previously utilized a portion of the existing WWTP site for land application of treated
wastewater. The permit has since been rescinded but the loading rates for the site provide useful
data in discussing this option.
The previous site was approximately 8 acres and the permit allowed for the application of up to
20,000 gpd of treated wastewater.This equated to approximately 2,500 gpd of discharge per acre
of available land or a discharge rate of 0.65 inches per acre per week.
For the purposes of this evaluation,the current application rate of 0.65 inches per week is utilized.
(The use of any area for land application would require an evaluation by a professional geologist
to determine the actual application rate available). Based on the previous application rate, the
application of 9 MGD would require approximately 3,600 acres not including buffers. Thirty
days of storage for wet periods would also be required. Based on a depth of 15 feet, the storage
pond would have a surface area of 36 acres.
The Economic Evaluation will review the land application option.

HARNETT REGIONAL WATER NORTH REGIONAL WWTP EXPANSION
ENGINEERING ALTERNATIVES ANALYSIS
FEBRUARY 2022
3.2.3 Wastewater Reuse
HRW actively pursues wastewater reuse options for the wastewater treatment facilities. At the
current time,there are no reuse options available for the treated effluent from the North Regional
WWTP.
3.2.4 Surface Discharge NPDES
The existing North Regional WWTP currently operates under a 7.5 MGD NPDES permit for
discharge to the Cape Fear River. The NPDES permit has seasonal poundage limits for TN and
TP that are the same as the poundage limits included in the 5.6 MGD NPDES discharge permit.
Speculative limits were received for an upgrade to 16.5 MGD. The proposed limits include the
same restrictions on seasonal poundage of TN and TP for a discharge of 16.5 MGD,as well as a
reduction in concentration limits for BOD5 and NH3.
Modifications to the existing process or the addition of treatment processes will be required to
meet the proposed discharge limits. This will include the construction of a new secondary
treatment process train. The existing facility including oxidation ditches and clarification units
will be utilized for sludge digestion and TP reduction.
3.2.5 Combination of Above
HRW currently utilizes a small portion of the existing 52-acre North treatment site for land
application. This area will be utilized for the expansion of the North facility.No onsite disposal
by land application will be considered with this evaluation.
The alternatives including the use of land application, transferring flow to the South Regional
facility and a surface discharge via an NPDES permit will be evaluated in the Economic
Evaluation section of this report.
The reuse option is contingent upon the availability of reuse options of which there are none at
the present time.
3.3 SUMMARY
The upgrade of the existing North Regional NPDES permit option is the most technologically
feasible option. All of the options will require construction of additional facilities for treatment
of the additional flow. The economic evaluations review the most feasible options for addressing
the capacity requirements at the North Regional WWTP.

ECONOMIC EVALUATIONS
4.1 GENERAL
As a part of the EAA, HRW evaluated Economically Feasible Alternatives for increasing the
wastewater treatment capacity from 7.5 MGD to 16.5 MGD. The disposal alternatives include:
• Connection to an existing WWTP(public or private),
• Land application including onsite subsurface, drip irrigation,or spray irrigation,
• Surface discharge through the NPDES program,or
• Combination of the above.
Reuse was not evaluated from an economic standpoint as there are currently no reuse options
available in this area.
4.2 ECONOMICAL ALTERNATIVES
Listed below is an evaluation of the alternatives listed above for the treatment of the additional
flow required to increase the discharge capacity of the North Regional WWTP from 7.5 MGD to
16.5 MGD.
All of the alternatives considered will require the expansion of a wastewater treatment facility
including connection to an existing wastewater treatment plant(South Regional).
4.2.1 Connection to an Existing WWTP(Public or Private)
The HRW South Regional WWTP is the only viable alternative for connection to an existing
WWTP.
The proposed project will include the construction of a pump station located at the North
Regional WWTP and a force main from the North Regional WWTP to the South Regional
WWTP. The South Regional WWTP has basins sized at 2.5 MGD with two basins per train for
a capacity of 5 MGD per train. There are currently three trains for 15 MGD.
Two evaluations will be performed including an expansion of 5 MGD (or roughly half the flow
needed) and an expansion of 10 MGD to accommodate the two options for addressing the
additional flows from the North facility.
The connection assumes that the South Regional WWTP NPDES permit could be updated to 24
MGD and that the nutrient loading would not change with the increased flow. If more stringent
TN and TP limits are placed on the South Regional WWTP,the cost for treatment will increase
for the entire facility which may require a process upgrade for the entire 24 MGD capacity.
NOTE: It would not be practical to operate two treatment trains with the blended effluent
meeting the requirement for a more stringent 24 MGD NPDES permit.

Transfer 4.5 MGD to South Regional WWTP
This option assumes half of the total increase of 9 MGD will be transferred to the South Regional
facility and half will be treated and discharged at the North Regional facility. This option would
require upgrades to both facilities.
The shortest route for a force main from the North Regional WWTP to the South Regional
WWTP is 14.5 miles.If half the flow is diverted to the South facility,a 24-inch force main would
be required and a pump station capable of handling the 2.5 peak would be constructed. The
project would include:
• New pump station with peak capacity of 11.25 MGD
• New 24-inch force main 77,500 LF
The cost to transfer 4.5 MGD of flow to the South Regional WWTP would be approximately$28
million.
The South Regional WWTP utilizes an SBR process(ICEAS)and includes tertiary treatment and
UV disinfection prior to the discharge. The following improvements would be required at the
South facility:
• Upgrade the existing headworks and splitter box
• Add a 5 MGD ICEAS treatment train
• Add filters and UV
• Expand the post aeration and increase size of outfall to river
• Add sludge digestion and dewatering
• Expand operations building
The total construction cost to upgrade the South Regional WWTP to accept half the proposed
upgrade to the North Regional WWTP (4.5 MGD) would be approximately $34 million. The
construction cost for the pump station and pipeline to transfer up to 4.5 MGD of flow to the South
facility would be approximately$28 million.
The North Regional WWTP would also require an expansion by 4.5 MGD with an estimated
construction cost of$36 million for a total construction cost of$98 million not including all soft
costs.
Transfer 9.0 MGD to South Regional WWTP
This option assumes the total increase of 9 MGD will be transferred to the South Regional facility
This option would require an upgrade to only the South Regional facility.
As stated above,the shortest route for a force main from the North Regional WWTP to the South
Regional WWTP is 14.5 miles. If a flow of 9 MGD is diverted to the South Regional WWTP, a
30-inch force main would be required and a pump station capable of handling the 2.5 peak would
be constructed. The project would include:
• New pump station with peak capacity of 22.5 MGD
• New 30-inch force main 77,500 LF
11

HARNETT REGIONAL WATER NORTH REGIONAL WWTP EXPANSION

FEBRUARY 2022
The construction cost to transfer 9.0 MGD of flow to the South Regional WWTP would be
approximately$32 million.
The South Regional WWTP utilizes an SBR process(ICEAS)and includes tertiary treatment and
UV disinfection prior to the discharge. The following improvements would be required at the
South facility:
• Parallel the existing headworks and splitter box
• Add a 10 MGD ICEAS treatment train
• Add filters and UV
• Expand the post aeration and increase size of outfall to river
• Add sludge digestion and dewatering
• Expand operations building
The construction cost to upgrade the South Regional WWTP to accept a flow of 9 MGD would
be approximately$55 million.
The total cost for transferring 9.0 MGD from the North Regional WWTP to the South Regional
WWTP for treatment and discharge would be approximately $87 million not including all soft
costs.
NOTE: Due to the increased cost of upgrading both treatment plants, only the 9 MGD
option is reviewed in the Economic Alternatives Analysis.
This evaluation assumes the South Regional WWTP NPDES permit can be expanded by 9
MGD without a substantial modification to the TN and TP limits.If the discharge limits for
the South Regional NPDES permit are modified, the total cost for upgrading the facility
will be increased.
4.2.2 Land Application
Land application assumes that a portion or all of the treated effluent from the 9 MGD expansion
of the North Regional WWTP will be land applied. If all the additional flow is land applied,the
North Regional facility will need to be expanded but the treatment process will not need to be
upgraded to meet more stringent effluent limits for TN and TP. If only a portion of the flow is
land applied versus surface discharge via the NPDES permit, the treatment process will require
an upgrade. The upgrade requirement will be based on the total flow that will be land applied.
Land application will require a transfer pump station,30 days of holding to address wet periods,
adequate land for application,and the irrigation equipment.
As a part of this evaluation,no suitable tracts of land have been identified. Assuming a weekly
application rate of 0.65 inches per week,it will require approximately 3,600 acres for application
of 9 MGD and 180 million gallons of storage to meet the 30-day request.Based on a depth of 15
feet,the storage would require 36 acres surface area.
In order to perform the financial evaluation, we have assumed that the suitable sites will be
located 15,000 LF from the WWTP,the property will be contiguous(to reduce application costs),
and the cost for the property would be $2,500 per acre.

Land Apply 9 MGD
The project would include the following:
• Pump station to transfer flow to application site
• Force main to site
• 30-day storage pond
• 3,600 acres of cleared property
• Irrigation equipment and pumping for 3,600 acres
• Land cover crop planted
The total construction cost for increasing the treatment capacity of the North WWTP to 16.5 MGD
and land applying 9.0 MGD from the North Regional WWTP would be$88 million without soft
costs and the cost for land which is estimated to be$10 million.
NOTE: This evaluation assumes the that adequate cleared land can be located within a
reasonable distance from the North Regional WWTP. At this time, no property has been
identified. The total cost for the project includes the addition of 9 MGD of treatment
capacity to the North Regional facility.The estimate also assumes no change to the NPDES
discharge for the existing 7.5 MGD NPDES permit.
4.2.3 Wastewater Reuse
HRW actively pursues wastewater reuse options for the wastewater treatment facilities. At the
current time,there are no reuse options available for the treated effluent from the North Regional
WWTP and a Net Present Worth analysis was not performed.
4.2.4 Surface Discharge NPDES
The North Regional WWTP holds an NPDES permit for a 7.5 MGD discharge to the Cape Fear
River. The North Regional site has adequate area for an expansion of the facility to 16.5 MGD
without impacting any previously undisturbed areas.
Speculative limits were received for an increase of the existing NPDES permit to 16.5 MGD.
The proposed limits maintain the current seasonal loading to the Cape Fear for TN and TP, and
also reduce the concentration limits for BOD5 and NH3.The proposed limits will require a process
upgrade for the secondary treatment processes and the sludge management facilities.The existing
facility has been evaluated and the improvements can be achieved without interruption of service
and on the available site.
The proposed project will include the expansion of the existing headworks, the installation of a
new low lift pump station to meet a modification to the hydraulic profile, a new secondary
treatment process designed to achieve the limits for TN and TP,tertiary treatment(expansion of
existing tertiary treatment),UV disinfection(expansion of the existing UV treatment), and post
aeration/discharge.
The proposed limits will require construction of a new 16.5 MGD treatment process which can
be constructed without interruption of the existing treatment processes. Following the
construction and startup of the new secondary treatment system,the existing secondary treatment
facility will be rehabilitated to function as sludge treatment to manage sludge and reduce the
reintroduction of TP into the treatment train.
13

HARNETT REGIONAL WATER NORTH REGIONAL WWTP EXPANSION

Additional improvements will include chemical feed systems,analytical equipment and
P Y YnSCADA,
and operations and laboratory facilities.
The total construction cost to expand the North treatment process to 16.5 MGD is $61 million,
not including soft costs associated with the project.
4.2.5 Combination of Above
The options reviewed above take into consideration the possibility of combining alternatives for
the improved project. Due to the substantial impact the increased capacity would have on the
North or the South treatment facility,the most feasible option is an upgrade to the existing North
Regional WWTP with no off-site construction requirements.
4.3 SUMMARY
The North Regional WWTP can be upgraded to a capacity of 16.5 MGD without impacting any
previously undisturbed area on the site and without any interruption to the existing treatment
processes. The upgrade will also maximize the use of existing treatment systems to meet the
long-term operation and needs of the North facility.
The upgrade of the North facility is the most cost effective alternative available to HRW as
outlined in the Economic Feasibility Review included in Appendix A.

SECTION 5
FINAL RECOMMENDATION
5.1 GENERAL
HRW is a true regional system that is responsibly utilizing the natural resources available to
provide critical infrastructure in the form of water and sewer to a large region of central North
Carolina. As an example, the HRW Water Treatment Plant serves citizens in five counties in
North Carolina,a rare distinction.
The North and South Regional wastewater systems are performing a similar role in central North
Carolina providing the reliable treatment and disposal of wastewater to a vast area. Due to their
location,the North and South Regional WWTPs are in the position of being requested to provide
expanded service to both a growing population and to areas that lack the resources to provide the
service to their citizens.
The North Regional WWTP has been planned and constructed with the intent of continuing to
serve as the regional provider for the northern portion of Harnett County and the southern portion
of Wake County (Cape Fear Basin). This report evaluated the treatment needs for the area and
options for disposal other than an increase to the current NPDES permit. The expansion of the
North Regional NPDES permit is the most feasible option technologically available to HRW and
the partners in the North Regional system.
The evaluation of the Cape Fear River is a key component in the future expansion of the North
Regional facility. The seasonal loading on the Cape Fear River for TN and TP was not increased
when the NPDES permit was increased from 5.6 MGD to 7.5 MGD and did not increase in the
Speculative Limits received for an NPDES discharge of 16.5 MGD. As the NPDES process
moves forward, HRW looks forward to the opportunity to meet with DEQ and review the
Speculative Limits and options for achieving the nutrient loading and the oxygen demand goals
in the Cape Fear River.

Aquaray® 3X Vertical Lamp UV System's features include:
• Third-Party validated per 2012 NWRI guidelines
• Easy maintenance without the need to remove equipment from channel for lamp and ballast
replacement.
• Automatic dose control is achieved by turning on/off lamps in combination with dimming in
relation to a flow signal, ensuring that the plant is operated economically while still providing
the required performance.
Option 1 -Two (2) Additional Channels
For the design flow of 16.5 MGD and a peak flow of 41.25 MGD and a UV transmittance of 65%, SUEZ
proposes to furnish two (2) additional UV channels to the existing system. Each channel will have UV
modules mounted one (1) across by three (3) UV banks in series.The proposed UV system will deliver
a UV dose of 30 mJ/cm2 at 41.25 MGD with one (1) UV bank out of service per channel. The dosage
calculation takes into account several factors including the end of lamp life and the quartz sleeve
transmittance factor.
Option 2 —All New Equipment - Four (4) Channel System
For the design flow of 16.5 MGD and a peak flow of 41.25 MGD and a UV transmittance of 65%, SUEZ
proposes to furnish four (4) UV channels. Each channel will have UV modules mounted one (1) across
by three (3) UV banks in series. The proposed UV system will deliver a UV dose of 30 mJ/cm2 at 41.25
MGD with one (1) UV bank out of service per channel. The dosage calculation takes into account several
factors including the end of lamp life and the quartz sleeve transmittance factor.

• The UV lamps are mounted vertically and perpendicular to the flow, where all electrical connections
are made out of the water. All the lamps are easily accessed through the lid of the top enclosure.
This makes routine service such as lamp changes, performed without having to remove the lamp
modules from the channel.
• Electronics, such as ballasts and communication cards, are all located in a remote enclosure away
from the UV channel
• The UV lamps are mounted in a uniform staggered array. This ensures a semi-tortuous path for the
effluent that avoids discharge of undisinfected wastewater.
• Flow pacing is achieved by a combination of dimming each row of lamps from 100% to 62% output
and turning lamp rows on and off in relation to a plant flow signal. Each UV module has six (6) rows
of lamps.
• Each UV module has a dedicated electric motor that powers a mechanical wiper. No failure of one
wiping system component will result in the loss of wiping capability for the entire UV system.
• All UV modules are completely removable from the UV channel, allowing for regularly scheduled
channel cleaning to remove algae or debris.

HIGH OUTPUT LAMP ARRANGEMENT:
The ultraviolet lamps are mounted vertically so that all electrical connections are made out of the water
and within the protection of an IP68 stainless steel enclosure. Unlike other designs, all the lamps are
easily accessed through the lid of this enclosure. Therefore, routine service such as lamp changes can
be made without having to remove the lamp modules from the channel.
The lamps are also mounted in a uniform staggered array, This ensures a semi-tortuous path so that
every particle of water will come into intimate contact with the most intense point of lamp output.
MODULE ARRANGEMENT:
The number and layout of the modules within the channel is determined based on the required UV
dosage and a UV path for the water that eliminates any possibility of hydraulic short-circuiting. See
"DESIGN BRIEF" for details of module arrangement for this project

FEATURES — UV LAMP MODULE
The heart of the system is the Aquaray® 3X lamp module is the high output, low pressure amalgam
lamps vertically mounted in a uniform staggered array of six rows of six lamps each. The lamps are
housed in quartz glass jackets, which are supported in neoprene holders with test tube ends. The top
end of the quartz jacket is sealed for submergence The UV module support structure includes a top
enclosure, four support legs and a bottom support pan, which are all manufactured from 316 stainless
steel.
All electrical connections are out of the water within the protection of the NEMA4X Power Center Panels.
Unlike other designs, each of these components and all of the lamps can be easily and quickly accessed
through the open lid of this enclosure. This allows routine service such as lamp changes to be made
without having to remove the lamp modules from the water. This significantly reduces maintenance
time and minimizes the possibility of breakage.
One UV intensity monitor is provided per bank of modules which continuously monitors and stores the
UV intensity and the status of each bank. Each lamp is polled and monitored for the number of hours
in operation, the number of on and off cycles and the date it was installed. This information is passed
to the control system and held in memory for subsequent recovery and integration.

FLOW PACING:
Due to the wide variety of flows that occur in a wastewater treatment plant, the Aquaray® 3X Vertical
Lamp System is designed to minimize energy consumption and extend lamp life by accurately
controlling the number and outputs of lamps in service. The Aquaray®3X"HO"System incorporates
a unique way of conserving energy via a combination of turning on/off and dimming of UV lamps.
This feature allows the system to switch on or off lamps and vary between lamp output power levels in
response to the flow pattern of the wastewater treatment plant via the 4-20mA signal received from the
plant flow meter.
During the diurnal flows described, the UV system will respond to the change in flows by turning on/off
lamps in increments of a '/2 banks and then dimming the lamps on a row by row basis.

SERVICE:
Every piece of equipment within a wastewater plant requires service. The Aquaray® 3X UV System
has been developed to permit easy troubleshooting and quick replacement of components. The majority
of maintenance activities can be carried out while the equipment is still located within the channel. The
recommended spares included in this proposal will ensure that the system can be maintained efficiently
and brought back to full operation in the shortest possible time.

Subject: Speculative Effluent Limits
N Harnett Regional WWTP
NC0021636
Harnett County
Cape Fear River Basin
Dear Mr. McGougan:
This letter provides speculative effluent limits for expanding the NE Regional WWTP located on
the Cape Fear River with a proposed flow of 16.5 MGD. These speculative limits supplement
those offered on October 1, 2021 for a proposed flow of 15.0 MGD. Speculative limits for 20
MGD were also requested, but the Division is unable to develop limits at that flow while holding
mass-loading constant as the resulting limits may not be achievable on a consistent basis for
current treatment technologies. Please recognize that speculative limits may change based on
future water quality initiatives.
Receiving Streams. The Cape Fear River at the outfall has a stream classification of WS-IV, and
waters with this classification have a best usage for aquatic life propagation and maintenance of
biological integrity, wildlife, secondary recreation, agriculture, and potable water use. The Cape
Fear River has a summer 7Q10 flow of 283 cfs, a winter 7Q10 flow of 304 cfs, a 30Q2 flow of
506 cfs, and an annual average flow of 3,172 cfs.
This segment of the Cape Fear River is not listed as an impaired waterbody on the 2020 North
Carolina 303(d) Impaired Waters List. The Cape Fear River does have downstream impairments
of chlorophyll a from nutrient enrichment and low dissolved oxygen. Nutrient criteria
development and modeling are currently underway to address these impairments and may affect
future permit limits.
Based upon a review of information available from the North Carolina Natural Heritage Program
Online Map Viewer, there are Federally Listed threatened or endangered aquatic species
identified within a 5-mile radius of the proposed discharge location. If there are any identified
threatened/endangered species, it is recommended that the applicant discuss the proposed project
with the US Fish and Wildlife Service to determine whether the proposed discharge location
might impact such species.

Speculative Effluent Limits. Based on Division review of receiving stream conditions,
speculative limits for an expansion to 16.5 MGD are presented in Table 1. A complete
evaluation of these limits and monitoring requirements for metals and other toxicants, as well as
potential instream monitoring requirements, will be addressed upon review of the formal NPDES
permit application which is under review. Some features of the speculative limit development
include the following:
• BOD/NH3/Nutrient Limits. With current modeling of the Cape Fear River underway,
no new models are being evaluated to develop limits for facilities in the modeled
segments. Therefore, mass-loading of oxygen consuming wastes have been frozen
based on current permit limits. These speculative limits can be re-evaluated once
current modeling is finished. These limits are expected to require advanced treatment
technologies.

Engineering Alternatives Analysis (EAA). Please note that the Division cannot guarantee
that an NPDES permit for a new or expanding discharge will be issued with these speculative
limits. Final decisions can only be made after the Division evaluates the formal permit
application for the expanded discharge. In accordance with North Carolina Administrative
Code 15A NCAC 2H.0105(c), the most environmentally sound alternative should be selected
from all reasonably cost-effective options. Therefore, as a component of all NPDES permit
applications for new or expanding flow, a detailed engineering alternatives analysis (EAA)
must be prepared (in this case we have this information which is under review). The EAA

must justify requested flows and provide an analysis of potential wastewater treatment
alternatives.
State Environmental Policy Act (SEPA) EA/EIS Requirements. A SEPA EA/EIS document
may be required for projects that: 1) involve $10 Million or more of state funds; or 2) will
significantly and permanently impact 10 or more acres of public lands. Please check with the
DWR SEPA coordinator (David Wainwright, 919-707-9045) as to whether your project
requires SEPA review. For projects that are subject to SEPA, the EAA requirements
discussed above will need to be folded into the SEPA document. Additionally, if subject to
SEPA, the NPDES Unit will not process an NPDES permit application for a new/expanding
discharge until the Division has approved the SEPA document and sent a Finding of No
Significant Impact (FONSI) to the State Clearinghouse for review and comment.
Should you have any questions about these speculative limits or NPDES permitting
requirements, please feel free to contact me at [e-mail]
