DEQ on February 27, 2024, and was prepared by Kurt Wright, PE, [e-mail]. It was prepared using the
guidance document titled DWQ Guidance Regarding the Reduction of Monitoring Frequencies in NPDES Permits for
Exceptionally Performing Facilities, October 22, 2012 (Guidance).
Approval Criteria — Based on the Guidance
1. This document has been prepared to meet the necessary Guidance requirements for the NPDES facility to
support a request for reduced monitoring.
2. The three-year period utilized in this analysis was 2021, 2022, and 2023.
3. The data table containing all the analytical results utilized in this analysis has been included in the data
transmission to the NC Department of Environmental Quality (DEQ) for the NPDES permit renewal application.
4. The Town of Spindale respectfully requests DEQ reduce the monitoring requirements for the following target
parameters:
a. BOD5
b. TSS
c. NH3-N
d. Fecal Coliform
5. No civil penalties have been assessed against the Spindale WWTP for the above target parameters.
6. Neither the permittee nor any of its employees have been convicted of criminal violations of the Clean Water Act
within the previous five years.
7. The Spindale WWTP is not currently under an SOC for the target parameters for effluent limit non-compliance.
8. The Spindale WWTP is not on the EPA's Quarterly Non-compliance Report for target parameter limit violations.
9. The three-year arithmetic mean for BOD5, TSS, and NH3-N is presented in Table 1 in Exhibit A. Table 1 shows that
for BOD5, TSS, and NH3-N, the three-year arithmetic mean of the effluent values is less than fifty percent of the
monthly average permit limit.
10. The three-year geometric mean for Fecal Coliform is presented in Table 2 below. Table 2 shows that for Fecal
Coliform, the three-year geometric mean is less than fifty percent of the NPDES permit requirement.

Wastewater Process Narrative and Biosolids Management Plan
Spindale Wastewater Treatment Plant, NPDES Permit No. NC0020664
The Spindale Wastewater Treatment Plant (WWTP) wastewater treatment process is based on extended air
activated sludge.
Historical Background of the WWTP
The original 6.0 MGD WWTP was designed in the late 1960s, with construction completed in 1970. Two
significant upgrade projects were completed in 1988 and 1999. The most recent project was a rehabilitation
of the plant at a cost of nine million dollars, completed in March 2020.
The rehabilitation consisted of several improvements while maintaining the principal wastewater treatment
process —extended air activated sludge. The following are key improvements pertinent to this Process
Narrative for the NPDES Permit Renewal application.
• The Average Daily Design Flow (ADDF) was reduced from 6.0 MGD to 3.0 MGD. This is due to the
passing of the textile era in Spindale. A 6.0 MGD WWTP, necessary for the high flows from the textile
industry, was no longer necessary.
• The original eight million gallon aeration basin was divided in half. One half was used for treatment,
and the other half was used for equalization of rainfall -induced high flows.
• The original eight million gallon Basin utilized eight one hundred horsepower surface -mounted
aerators manufactured by Simcar for combined mixing and oxygen addition for the microbiology in
the extended air activated sludge process.
• The WWTP rehabilitation project replaced the original one hundred horsepower Simcar units with a
fixed bottom fine bubble aeration system, utilizing two-inch diameter diffusers. This new aeration
system provides the mixing and oxygen addition for the microbiology in the extended air activated
sludge process.
• The air supply for the aeration system is provided by one hundred fifty horsepower rotary lobe
positive displacement blowers (Blower), capable of delivering 3,000 standard cubic feet per minute
of airflow. There are a total of three Blowers.
• The "Treatment Side" of the Basin:
o As mentioned above, the original eight million gallon basin was divided in half, each
containing four million gallons. One half is dedicated to treating the wastewater, hence the
"Treatment Side."
o The Treatment Side consists of a total capacity of four million gallons.
o The four million gallon basin is further subdivided into two smaller basins, each containing
two million gallons.
o Each two million gallon subbasin is designed to treat an ADDF 1.5 MGD.
o Both subbasins can treat up to an ADDF of 3.0 MGD together.
o The air supply for each subbasin's fine bubble aeration system is provided by a one hundred
fifty horsepower Blower, as mentioned previously.
o Therefore, there are two Blowers, one Blower for each subbasin. A third Blower is for
redundancy.
o Any of the three Blowers can be used for either subbasin; they are interchangeable.
11P'iF,

o The fine bubble system includes automated air control valves, air pressure sensors, air flow
meters, and Dissolved Oxygen and Temperature sensors. This data is fed into a Programmable
Logic Controller (PLC).
o The three 150 HP Blowers are each driven by a variable frequency controller (VFC).
o The PLC and VFC combine to control the speed of the Blower based on preset algorithms
utilizing the data from the flow meters and sensors.
• The "Flow Equalization" side of the Basin
o As mentioned above, the original eight million gallon basin was divided in half, each
containing four million gallons. One half is dedicated to "Flow Equalization" (EQ).
o The EQ side has a total capacity of approximately four million gallons.
o The EQ side receives high flows from significant rain events.
o The high flows are shaved off from the influent wastewater flow passing through a junction
box (Junction Box No.1).
o These high flows are stored in the EQ basin until the rain event subsides. The flows are bled
back into the Treatment Side during normal flow conditions.
WWTP Rehabilitation Project Design Basis
The rehabilitation design was based on the wastewater treatment plant achieving the effluent limits in the
current NPDES Permit for an ADDF of 3.0 MGD with a Maximum Flow of 9.0 MGD. The NPDES Permit limits
for the design basis are presented below.
• Biochemical Oxygen Demand, 5-day, 20 deg. C (BOD5): Monthly Average 22.5 mg/L, Weekly Average
38.2 mg/L
• Total Suspended Solids (TSS): Monthly Average 30.0 mg/L, Weekly Average 45.0 mg/L
• Ammonia (NH3-N) Summer: Monthly Average 4.4 mg/L, Weekly Average 13.2 mg/L
• Ammonia (NH3-N) Winter: Monthly Average 10.0 mg/L, Weekly Average 30.0 mg/L
• Dissolved Oxygen (DO): Daily Average equal to or greater than 6.0 mg/L
• Fecal Coliform (geometric mean): Monthly Average 200/100 mL; Weekly Average 400/100 mL
• Total Residual Chlorine (TRC): Daily Maximum 28.0 ug/L
• pH: Between 6.0 and 9.0 Standard Units
When the strength of the influent wastewater is normal, as defined by Metcalf & Eddy, 4`h Edition, the
wastewater treatment plant can achieve 85% removal of BOD5 and TSS. The design loading is 4,000 pounds
per day of BOD5 and 300 pounds per day of NH3.
It should be pointed out that if the influent wastewater flow contains a significant amount of Infiltration and
Inflow (1/1) such that it dilutes the normal strength of the influent wastewater (Metcalf & Eddy) entering the
Treatment Side to levels below 100 mg/L for BOD5 and TSS, 85% removal may no longer be true due to the
weak strength of the influent flow. The EQ basin is intended to mitigate this occurrence.
WWTP Process Flow Diagram and Description
Figure 1 (a separate document) provides a process flow diagram. The process flow diagram is explained as
follows.
The influent flow to the WWTP comes from two main interceptor sewers, which combine in a manhole
outside the fence of the WWTP.
2 1 P1 ge

1
The combined influent flow enters the plant and is discharged into a junction box. From there, it is directed
to the Headworks Facility.
The Headworks Facility consists of these key functions:
• Influent Sampling (24-hr composite)
• Mechanical Bar Screen
• Bypass Manual Bar Screen
• Flow Diversion Gates
• Parshall Flume
• Grit Removal Facility (Detritor Grit Removal unit)
• Addition of Sodium Hydroxide (NaOH) to enhance background alkalinity
The flow from the Headworks Facility is then conveyed to Junction Box No. 1, installed with the Rehabilitation
Project.
Junction Box No. 1 consists of these key functions:
• The primary function is to pass the normal, diurnal wastewater flow to the Treatment Side.
• The secondary function is to shave off high flows induced by significant rain events and divert them
into the EQ side.
• The storm -induced flows are then bled back into the Treatment Side during normal flow conditions.
The normal diurnal wastewater flow passes through Junction Box No.1 and is conveyed to Junction Box No.
2, which was installed with the rehabilitation project.
Junction Box No. 2 consists of these key functions:
• The primary function is to enable the wastewater to be directed to one or both subbasins in the
Treatment Side.
• The secondary function is to receive the storm -induced flows from the EQ side as they are bled back
into the Treatment Side.
The flows are then treated by the extended air activated sludge process in the Treatment Side of the Basin.
The key functions of the Treatment Side of the Basin are as follows:
• The Treatment Side of the Basin is the aeration basin for the extended air activated sludge process.
• It contains the necessary microbiology to treat the wastewater.
• The fixed bottom fine bubble aeration system blows air from the two-inch diameter diffusers at the
bottom of the Basin. As these bubbles escape and make their way to the surface, they provide the
necessary mixing of the microbiology in the mixed liquor solids and introduce oxygen into the mixed
liquor to maintain the life of the microbiology.
• The wastewater flows out of the aeration basin through the effluent boxes.
The wastewater flows from the aeration basin via the effluent boxes into the diversion manholes for the
Clarifiers. There are multiple diversion manholes to enable the operator to direct the effluent to the
Clarifier(s) of choice.
There are three clarifiers; two are 65 feet in diameter, nine feet deep (original), and one is 100 feet in diameter,
twelve feet deep (installed during a previous upgrade). The clarifiers settle the wastewater and enable the
microbiology to settle at the bottom, where the Return Activated Sludge Pumps remove it. The Return
31 Page

Activated Sludge, or RAS, is pumped back to the head of the aeration basins to maintain the microbiology in
the treatment process.
Wastewater flows from the Clarifiers via diversion manholes to the Chlorine Contact Tanks (CCT). There are
two, one of which is for redundancy. Chlorine is introduced before the effluent reaches the CCT. After the flow
has passed through the CCT, the operator can further aerate the effluent with modular positive displacement
blowers. The final step is the addition of Sulfur Dioxide (SO2) to dechlorinate the effluent.
After SO2 addition, the final effluent passes through a flow meter and enters the Outfall Line to Catheys Creek.
WWTP Biosolids Management
• Excess sludge from the Clarifiers or waste activated sludge (WAS), which must be removed to enable
the operator to maintain the proper Mixed Liquor Volatile Suspended Solids (MLVSS) in the aeration
basin, is pumped to the two digesters.
• The two digesters store and treat the WAS to meet Class B requirements (biosolids).
• A residuals management contractor removes the biosolids and legally applies it to farmland under
Permit No. WQ0001953. This Permit was effective on May 1, 2020, and expires on April 30, 2026.
• The contractor is US Biosolids, Ronda, NC. https://www.usbiosolids.com/

Mercury Minimization Plan (MMP)
Spindale Wastewater Treatment Plant
NPDES Permit No. NCO020664
Spindale, NC
Adopted March 26, 2014
Revised February 23, 2024
INTRODUCTION AND BACKGROUND
The following information was contained in the North Carolina Department of Environment and Natural
Resources (DENR) Model Mercury Minimization Plan and is copied here (verbatim) in this specific plan
as an introduction.
The North Carolina Department of Environment and Natural Resources, Division of Water Quality
(DENR), has issued a statewide total maximum daily load (TMDL) for mercury. The TMDL responds to
a statewide fish consumption advisory for mercury. The TMDL calls for a 67% reduction in mercury
levels from the year 2002 baseline mercury loading. The ultimate goal of the TMDL is to ensure safe
levels of mercury in fish throughout North Carolina for human consumption.
As explained in the TMDL, 98 percent of mercury in North Carolina waters comes from atmospheric
sources — the vast majority of which are located outside of the State. Under the Clean Water Act,
atmospheric deposition of mercury into surface waters is regarded as a nonpoint source. Minor amounts
of mercury are discharged directly into surface waters by industrial and municipal point sources as a
group. Specifically, the TMDL determined that point sources contribute less than two (2) percent of the
annual mercury loadings to State waters. The TMDL allocates two percent of the statewide allowable
loadings collectively to the point source sector. This does not mean that an individual discharger may not
have significant levels of mercury in its discharge in terms of local water quality considerations. While
we expect such instances to be rare based upon the Department's review of statewide mercury data,
dischargers with higher mercury loadings will be expected to implement more aggressive mercury
controls.
Notably, unlike any other source, local governments actually reduce mercury loadings in the environment
by first filtering mercury out in the treatment of public drinking water (particularly where the source of
raw drinking water is surface water) and then a second time when wastewater is treated.
In order to implement the two percent point source sector waste load allocation, the Department has
developed a point source permitting strategy which is located at
http://portal.ncdenr.or web wwq/ps/mtu/tmdl/tmdls/mercury . The Environmental Management
Commission has approved both the TMDL and the Permitting Strategy. The permitting strategy calls for
certain point sources to develop and implement mercury minimization plans (MMPs). For POTWs, an
MMP will be required if the facility has (1) a permitted design capacity of more than two million gallons
per day and (2) mercury at quantifiable levels in their effluent. MMPs feature best management practices
and have been implemented successfully in numerous states around the country. The attached document
is Town of Spindale's MMP.
Typically, MMPs focus on pretreatment controls — a local government's interaction with non -domestic
users of its sewer system as well as outreach to the public at large regarding the proper use and disposal of
household products containing mercury.

Town of Spindale, NC Mercury Minimization Plan (MMP)
The MMP approach is intended as a reasonable, low-cost approach toward making some progress toward
managing the two percent loading statewide from point sources. Mercury treatment and even testing is
very expensive and does not make sense to reduce a small part of the already insignificant two percent
overall point source annual loading to State waters.
SECTION I - PURPOSE
This Mercury Minimization Plan (MMP) is based on the Model Mercury Minimization Plan prepared by
the NC Department of Environment and Natural Resources. The model has been tailored to the Town of
Spindale.
The purpose of this MMP is to describe best management practices through which the Town of Spindale
will seek to reduce the amount of mercury discharged into its system and, ultimately, to the environment.
The MMP compiles mercury reduction -related efforts to -date and potential future action items. It is
designed to be a working document to help the Town in its efforts to control mercury loadings discharged
into its Publicly -Owned Treatment Works by users of the sewer system. Such a reduction in loadings to
the sewer system should translate to a reduction in the amount of mercury which is discharged from the
wastewater treatment plant. The management practices summarized below may also help control some of
the mercury reaching our storm sewer system as well.
This MMP is based on the Model Mercury Minimization Plan prepared by the NC Department of
Environment and Natural Resources. The model has been tailored to the Town of Spindale.
SECTION II — FACILITY DESCRIPTION
The Town owns and operates a Publicly -Owned Treatment Works (POTW), including a collection and
conveyance system and one 3.0 MGD wastewater treatment plant (WWTP), that serves the residential
users, the commercial and other non-residential users, and industrial users of the Town of Spindale, North
Carolina.
The wastewater treatment process is briefly described below.
The wastewater treatment process consists of a headworks facility which includes a mechanical
screen with a bypass bar screen, a Parshall flume and grit removal system. From there the
wastewater flows into one of two 1.5 MGD aeration basin. In this basin there is a fine bubbler
diffuser system. The fine bubble diffusers are supplied by 1 of 3 blowers. From there the
wastewater flows to one 110-foot diameter clarifier currently under review for refurbishment or
two additional, identical 75-foot diameter clarifiers. The solids are settled out in these two
clarifiers, some of which is returned to the aeration basin as RAS (return activated sludge) and
some is wasted to the digester as WAS (waste activated sludge). The treated wastewater flows
over the weirs in the two 75' foot clarifiers to the disinfection system. Here the effluent is treated
first with chlorine (C12) to kill bacteria and viruses. Then sulfur dioxide (SO2) is added to reduce
the amount of chlorine left in the effluent. The final step is to add additional oxygen, if needed,
with post disinfection blowers followed by final effluent flow metering. The final treated effluent
flows from the wastewater treatment plant by gravity to the discharge point in Cathey's Creek.
Most municipal treatment plants are not designed to remove mercury and it is exceedingly expensive to
do so to very low levels. Incidental mercury removal occurs through typical municipal treatment with
trace levels of mercury (and other metals) ending up in solids removed from the raw wastewater.
Mercury is not used in the treatment processes at the WWTP. Mercury may be introduced into the sewer
system through a variety of sources, such as from industrial users, laboratories, and other businesses.

Mercury Minimization Plan (MMP)
Residual deposits of mercury are also possible in the sewer system from historic practices. Finally, trace
amounts from household products and atmospheric deposition (both wet and dry) contribute to sewer
system mercury loadings.
While there is typically some mercury contributed to public sewer systems statewide, it is usually in
minute quantities and comprises a tiny portion of the already insignificant statewide loading for all point
sources -just two percent of the annual mercury loadings to all State waters.
It should be pointed out that the Duke Power coal-fired power plant is within 14 miles (direct) from the
Spindale WWTP. Off gases from coal-fired power plants have been known to contain mercury. Refer to
Figure 1 in Attachment A. It is possible that atmospheric conditions may have resulted, from time to
time, in atmospheric deposition at the Spindale WWTP of trace quantities of mercury emanating from the
Duke facility.
SECTION III — PROGRAM PLAN
A. EVALUATION OF POTENTIAL NON -DOMESTIC SOURCES CONTRIBUTING
MERCURY TO THE POTW
The Town will evaluate available information to assess the potential for non -domestic users of the sewer
system to contribute mercury to the system. The information to be reviewed may include: (1) POTW
influent and effluent mercury data and trends; (2) industrial user permits and associated mercury
monitoring data; (3) Toxics Release Inventory (TRI); (4) state hazardous site registry and the National
Priority List relating to mercury contamination; and (5) historical records of industrial sites which have
contributed mercury loadings to the sewer system.
The Town conducted a dental amalgam survey in 2020 of all dentists within the town limits.
The Town will request that industrial users review mercury concentrations in high -volume process
chemicals and demonstrate that the mercury concentrations are below industry average. The Town will
request that alternative sources for chemicals be explored if the mercury levels are determined to be
significantly higher than would normally be expected.
The evaluation of potential non -domestic sources of mercury to the sewer system will be updated every
five years, as warranted by prior sampling results and any additional new potentially significant sources to
the system.
B. ADDITIONAL CONTROL MEASURES
This MMP identifies reasonable and cost-effective control measures to minimize mercury being
discharged into the POTW. Below is a listing of initial BMPs for this POTW.
Pollution Prevention
Substances used at the WWTP will be evaluated to determine if they contain mercury or mercury -based
compounds. Any such chemicals will be evaluated for substitution with non -mercury -containing
substances.
Page 3

Town of Spindale, NC Mercury Minimization Plan (MMP)
Housekeeuing. Saiill Control and Collection. and Education
The Town will develop procedures to minimize the possibility of any spill or release at the WWTP
involving mercury containing substances. The Town will add mercury identification and proper disposal
to ongoing and future operator training procedures.
Public Outreach
The Town will make available educational information regarding sources of household mercury and
appropriate use/disposal practices. This information may be posted on the Town's website. The
availability of this information will be highlighted in the Town's semi-annual outreach to the Town's
customers. The Town will also facilitate public awareness regarding community collection points for
mercury -containing products from residents/customers for proper disposal. Periodic reminders of such
collection programs will be provided as part of the Town's ongoing public outreach.
C. TRACKING AND MONITORING
In order to assess the implementation of the control measures, the Town proposes to undertake the
following evaluations beginning after the first full year that this MMP is implemented:
1. Survey annually at least ten percent (10%) of any non -domestic users identified as
possible significant sources of mercury to the POTW;
2. Track the implementation of the programs outlined above;
3. Monitor influent mercury at least annually. Require significant non -domestic sources of
mercury to monitor periodically, as warranted; and
4. Measure effluent mercury as required by the NPDES permit.
These efforts will allow the Town to establish a baseline of influent and effluent mercury levels to assist
in identifying any trends in mercury contributions from domestic and non -domestic users of the sewer
system. This baseline will be tracked annually.
SECTION IV — IMPLEMENTATION OF CONTROL MEASURES
The Town will implement the control measures summarized in Section III over the permit term and will
update this MMP as warranted.
SECTION V - REPORTING
A summary of the MMP activities will be submitted as part of the NPDES permit renewal process.
