The Town of Fuquay-Varina Public Utilities Department is permitted to discharge 6.0 million gallons per
day (mgd) of treated effluent from the Terrible Creek Wastewater Treatment Plant (WWTP) to Terrible
Creek under North Carolina NPDES Permit NC0066516. This NPDES permit is scheduled to expire on
April 30, 2019. The enclosed application is for the renewal of this permit. In accordance with the
requirements of federal (40 CFR 122) and state (15A NCAC 2H .0105(3)) regulations, we are submitting
three signed copies of the completed application package and associated attachments and figures. The
application package includes the following information:
• NPDES Permit Application — EPA Form 2A
• EPA Form 2A Additional Information (Topographic Map, Site Map, Process Flow
Diagram and Process Narrative)
• Terrible Creek WWTP Sludge Management Plan
• Summary of First Species Effluent Toxicity Testing, 2015-2018
• Annual Priority Pollutant Analysis Results, 2015-2018
• Technical Memorandum in support of the Reduction of Monitoring Frequency for
Exceptionally Performing Facilities
At the time of this application submittal, the required second species toxicity testing events have not yet
been completed. The four second species effluent toxicity tests are currently scheduled to be completed
in October 2018, November 2018, December 2018, and January 2019. When the toxicity test results
become available, they will be forwarded to the Division of Water Resources (DWR) along with revisions
to Part D of EPA Form 2A to include these results. All of the second species toxicity tests will be
submitted prior to the current permit expiration date of April 30, 2019.
In accordance with 15A NCAC 2B .0508(b)(1) and the October 2012 DWR Guidance Document for the
Reduction of Monitoring Frequency for Exceptionally Performing Facilities, the Town of Fuquay-Varina
respectfully requests a reduction in frequency monitoring for biochemical oxygen demand (BOD5), total

suspended solids (TSS), and fecal coliform bacteria. Effluent sampling results from the past three years
demonstrate that all state regulatory and guidance requirements have been met in support of this request.
A complete summary of the sampling data and analysis for the reduction of monitoring frequency is
attached in Tab G of this application.

Influent Pumping and Preliminary Treatment
The Terrible Creek Wastewater Treatment Plant (WWTP) operates an influent pump station with
a total of six (6) submersible pumps and a firm pumping capacity of 9 mgd. The influent pump
station receives flow from a 24-inch gravity main into an influent channel, which then passes
through a mechanically cleaned coarse bar screen. Following the coarse screen flow can be split
between two influent wet wells, each of which contain two larger capacity pumps (40 HP) and
one smaller capacity pump (25 HP). The WWTP influent is then pumped through a single
18-inch force main to the preliminary treatment facility (PTF), which includes fine screens and
grit removal processes.
Upon entering the PTF, flow is split between two screenings channels with 1/4-inch
mechanically cleaned step screens. A third influent channel with a manually cleaned 1-inch bar
rack is also available. After passing through the screenings channels, flow is then directed
through two Eutek Headcell stacked plate style grit removal cells, ten (10) six-foot diameter
trays. After passing through the grit collection cells, flow is then conveyed to a distribution box,
which splits flow between two circular biological nutrient removal (BNR) basins.
Secondary Treatment
Secondary treatment is provided through two 125-foot diameter, circular, 5-stage conventional
BNR basins. Flow enters the basin in the center, which is an anaerobic zone. Following the
anaerobic zone, flow goes through the first anoxic zone in an intermediate annular ring, an
aerobic zone, a second anoxic zone, and finally a reaeration zone in the outer annular ring of the
basin. Fine bubble diffusers are used for aeration and platform mounted mixers are used in the
anaerobic and anoxic zones. Window pumps are used for recycling nitrified mixed liquor from
the aerobic zone to the first anoxic zone. Following the BNR basins, flow is conveyed to a
distribution box, where it is distributed to the two secondary clarifiers.
There are two 85-foot diameter, 16-foot sidewall depth secondary clarifiers. The clarifiers are
upfitted with suction header type sludge removal systems and rotating trough style scum
removal. As part of the activated sludge process, settled activated sludge from the secondary
clarifiers is recycled to the influent of the aeration basins (return activated sludge or RAS). A RAS
pump station pumps RAS from the two clarifiers to the PTF effluent piping, upstream of the BNR

Town of Fuquay-Varina
Terrible Creek WWTP
NPDES Permit No. SC0066516
Outfall 001
basin distribution box. Secondary clarified effluent is conveyed to the WWTPs tertiary filtration
system.
The Terrible Creek WWTP has the capability to feed three different chemicals to assist in the
WWTP treatment processes. The plant has the ability to feed soldium hydroxide (caustic) to
primary effluent upstream of the BNR basins to provide supplemental alkalinity for nitrification.
Supplemental carbon can be added in the BNR basins as an external source of readily
biodegradable carbon for heterotrophic denitrifying bacteria if needed. Alum is capable of
being added upstream of secondary clarifiers for chemical phosphorous removal.
Filtration & Disinfection
Secondary clarified effluent is conveyed to the WWTP's two Leopold Ultrascreen disk style
filtration units. Each filter unit consists of stainless steel mesh media mounted on circular disks,
through which forward flow must pass. The filter units each contain 12 stainless steel media
mounted disks. The disks rotate during filtration and provide an effective filtration pore size of
10 micrometers (µm). After passing through the filter media, filtered effluent is then combined
and conveyed to the WWTP UV disinfection system.
The UV disinfection system consists of two UV disinfection channels, each with two service and
one redundant bank of UV lamps. The UV system is a TrojanUVSigna System with eight UV
lamps per bank. Following UV disinfection, treated effluent is conveyed through flow
measurement and effluent sampling and ultimately to the outfall at Terrible Creek.
Solids Treatment
Residuals generated during the liquid treatment process are removed from the liquid treatment
train to maintain an equilibrium concentration of activated sludge solids in the biological
treatment tanks. The excess residuals or waste activated sludge (WAS) are removed from the
liquid treatment process in the return activated sludge stream. WAS is capable of being
pumped from the WAS pump station to either a sludge holding tank or a gravity belt thickener.
The sludge holding tank receives sludge from the WAS pump station and the thickened WAS
(TWAS) pumps when the dewatering unit is operating in thickening mode. WAS is removed from
the sludge storage tank by the sludge feed pumps located in the solids handling facility. The
sludge storage tank has a 61.5-ft diameter by 18-ft sidewater depth with a volumetric capacity
of approximately 400,000 gallons. Aeration and mixing capability is proposed via a fine bubble
membrane diffuser system. An aeration rate of 20 cfm per 1000 cubic feet keeps solids aerated
and in suspension.
The Terrible Creek WWTP solids dewatering facility provides dewatering of WAS. The
dewatering facility consists of two (2) 3-belt filter presses (BFPs), with a gravity belt thickener

Town of Fuquay-Varina
Terrible Creek WWTP

Outfall 001
located just upstream of the filter press. The 3-belt presses have an operating width of two
meters and are designed for a maximum solids loading rate of 1,500 dry pounds per hour and a
maximum hydraulic loading rate of 400 gallons per minute. Dewatered residuals are conveyed
to a truck loading facility and loaded in trucks for offsite composting.

Fuquay-Varina Terrible Creek WWTP
Residuals Management Plan
Overview and Summary
The Town of Fuquay-Varina operates the Terrible Creek Wastewater Treatment Plant (WWTP) which
discharges treated effluent to the Terrible Creek in the Neuse River basin. The WWTP is currently
operating under a permitted discharge flow of 3.0-mgd.
The solids handling processes at the Terrible Creek WWTP:
• Provide raw waste activated sludge thickening by utilization of two "3-belt" dewatering units
capable of independent operation as a gravity belt thickener which can produce a thickened waste
activated sludge product. Liquid residuals storage for this material is provided via an
interconnection with the sludge storage tank. Additionally, thickened waste activated sludge
product can also be routed to a liquid loadout facility.
• Provide process capability to produce a belt filter press dewatered cake product from the
treatment facility. The dewatered cake produced is then routed to off -site composting facilities
(McGill Environmental, New Hill, NC).
Trash, Sediment and Grit
The Terrible Creek WWTP process design includes coarse (influent pump station) and fine (preliminary
treatment facility) screens for the removal of trash and sediment from the liquid treatment trains. The
preliminary treatment facility also includes a grit removal system composed of a grit concentrator and
grit washing/classification unit. Both the influent pump station and the preliminary treatment facility
are designed with screenings collection capabilities for short-term storage, prior to being transported to
an offsite landfill facility.
Estimated Residuals Production Rates
Undigested (raw) residuals production rates were estimated for the facility based on a BioWin® process
model developed for the WWTP. The BioWin® process model utilized historical influent BOD, TSS, and
other wastewater characteristics in developing estimates for treatment facility process performance and
residuals production rates.
The estimated residuals production rates for the facility are as shown in Table 1.

Residuals Handling Facilities
The Terrible Creek residuals handling facilities include the following process components:
• Waste Activated Sludge Pumping
• Liquid Sludge Storage
• Raw Sludge Thickening and Dewatering
• Liquid Sludge Loading and Handling
These facilities are further described in the following sections.
Waste Activated Sludge Pumping
Waste activated sludge has the same solids concentration as the plant's return activated sludge (e.g.,
secondary clarifier underflow concentration). Waste activated sludge branches off of the RAS pump
discharge header inside the RAS pump station building. The WAS flow is measured with a magnetic flow
meter and controlled using a motor operated modulating plug valve. The WAS is routed to the sludge
storage tank for storage or to the dewatering building for thickening or dewatering.
Sludge Storage
Raw waste activated sludge storage is provided in a 61.5-ft diameter x 18-ft sidewater depth holding tank
with a volumetric capacity of approximately 400,000 gallons. Aeration and mixing are provided in this
tank by fine bubble membrane diffusers. Underflow from this tank is routed to the dewatering facility
where raw waste activated sludge can be: (1) further thickened and sent back to the sludge storage tank
(recuperative thickening operations mode) or liquid loadout; or (2) fully dewatered and routed to off -site
management facilities (e.g., off -site composting).
Under normal operating conditions, the Terrible Creek WWTP design provides for 6.5 days of residuals
storage for un-thickened WAS at 7,000 mg TSS/L concentration. The solids processing design also includes
provisions to increase the residual storage capacity at the plant to greater than 30-days when required,
by thickening the sludge with a gravity belt thickener prior to storage in the sludge storage tank and/or
the use of the gravity belt thickening process in a recuperative thickening operational mode. The methods
and derivation of the design sludge storage capacity under both normal operating and during periods
where additional residual storage capacity is required are outlined in the paragraphs below.

When conditions dictate that greater than 6.5 days of residuals storage will be required, WAS is wasted
to the gravity belt thickener section of the dewatering equipment. After being processed through the
gravity belt thickener, the thickened sludge is directed to the TWAS pump station instead of continuing to
the belt filter press. The thickened sludge is then pumped by the TWAS pumps to the sludge storage tank.
The solids processing system was designed to allow for greater than 30-days of residual sludge storage
when operating conditions dictate. The gravity belt thickener is designed to process sludge with up to a
4% solids concentration. Both the Sludge Feed and TWAS pumps are also designed to allow for pumping
sludge with a 4% solids concentration.
The Terrible Creek WWTP residual storage design allows for the storage of thickened WAS up to a 4%
solids concentration. The calculations demonstrate that greater than 30-days of onsite residual storage
is available at the WWTP, in accordance with 15A NCAC 02T .0505(o), when the solids concentration of
the sludge stored in the sludge storage tank is raised to 3.5%. When solids concentrations exceed 2.5% in
the sludge storage tank, aeration of the tank will cease until normal operating conditions resume. The
lack of aeration will not have an impact on the storage of sludge in the tank.

Raw Sludge Thickening and Dewatering
Residuals dewatering facilities include a solids handling building outfitted with two 2.0-meter width
dewatering units. The units are "3-belt" dewatering units which are characterized by an independent
gravity belt thickener coupled with a conventional 2-belt belt filter press dewatering unit. The 3-belt
system provides the capability to operate in either a "thickening" or "dewatering" dual duty operating
configuration. The 3-belt units provide the capability to produce a dewatered cake product which can be
transported off -site for management and/or disposal.
The dewatering unit thickening capacity is approximately 400 gallons per minute (hydraulic loading limit)
and 1,500 dry pounds per hour (solids loading limit). Estimated dewatering unit system capacity utilization
at the design flow rate is summarized in Table 4 with a single unit operating in dewatering mode with a
raw waste activated sludge feed stock.

Sludge feed pumping, polymer make-up and feed equipment, and dewatered cake conveyance equipment
support overall system redundancy and reliability objectives to minimize "single point of failure" systems
in sludge feed pumping and polymer conditioning sub -systems. Thickened waste activated sludge pumps
are provided in the solids handling building to transfer thickened material from the independent gravity
deck to the sludge storage tank or to the liquid loadout station.
Liquid Sludge Loading and Handling
The liquid loading station is fed from the TWAS pumps located in the dewatering building. Capability is
provided to allow liquid loading of un-stabilized materials for off -site management.

Residuals Disposal and Management Options
Dewatered cake is conveyed to a truck loading facility and loaded into trucks for off -site disposal.
Dewatered cake is then trucked to McGill Environmental's composting facility in New Hill, NC. At this
facility the un-stabilized residuals are converted to a Class A compost material.

Public Utilities Operation Manager
From:
Tim Devine, PE / Mary Sadler, PE
Date:
October 17, 2018
Subject:
Reduction of Monitoring Frequency for Exceptionally Performing Facilities
Terrible Creek Wastewater Treatment Plant
In support of the National Pollutant Discharge Elimination System (NPDES) permit renewal, a monitoring
frequency reduction analysis was conducted on the Terrible Creek Wastewater Treatment Plant (WWTP)
Discharge Monitoring Report (DMR) data between August 2015 and July 2018. The monitoring frequency
reduction analysis was performed in accordance with the Division of Water Resources (DWR) guidance
document, Reduction of Monitoring Frequencies in NPDES Permits for Exceptionally Performing Facilities
(October 2012). Per DWR guidance, the following criteria has been met by the Town of Fuquay-Varina:
• The Terrible Creek WWTP has not had any civil penalty assessments for permit limit
violations for either biochemical oxygen demand (BOD5), total suspended solids (TSS),
or fecal coliform.
• The Town of Fuquay-Varina and Terrible Creek WWTP employees have not been
convicted of any criminal violations of the Clean Water Act (CWA).
• The Terrible Creek WWTP is not currently under a Special Order of Consent (SOC).
• The Terrible Creek WWTP is not on EPA's Quarterly Noncompliance Report for either
BOD5, TSS, or fecal coliform.
Table 1 provides a summary of DMR data from August 2015 through July 2018. The data supports a
reduction in the monitoring frequency for BOD5, TSS, and fecal coliform. The three-year arithmetic mean
of effluent data is less than 50 percent of the monthly permit limit for BOD5 and TSS. The three-year
geometric mean of effluent data is less than 50 percent of the monthly permit limit for fecal coliform. Less
than 15 of the daily effluent sampling results are over 200 percent of the monthly average limit for BOD5
and TSS. Less than 20 of the effluent sampling results are over 200 percent of the weekly average limit for
fecal coliform. The Excel Spreadsheet, NPDES Permit NCO066516 MRF.xlsx, contains the data for the
monitoring reduction frequency analysis. This spreadsheet will be transmitted to DWR upon request.
The Terrible Creek WWTP has met the requirements to be categorized as an Exceptionally Performing
Facility per DWR guidance and is eligible for a reduction in the monitoring frequency of BOD5, TSS, and
fecal coliform bacteria.

2 Analysis is representative of data from August 2015 through July 2018.
3 BOD5, Ammonia, and TSS values represent the arithmetic mean. Fecal Coliform value represents the geometric
mean.
4 Terrible Creek WWTP had 27 effluent samples from August 2015 through July 2018 with DMR recorded fecal
coliform concentrations of `56001100mL". These samples were not included in the count of effluent samples over
that time period that exceeded a fecal coliform concentration that is 200% of the weekly average limit or
8001100mL.
5 Terrible Creek WWTP had an average effluent fecal coliform concentration of 4751100mL on the week beginning
512912018. This is the only one -week period in the previous year where the permitted weekly average was
exceeded.
