4. Instream Data Summary
Instream monitoring may be required in certain situations, for example: 1) to verify model predictions
when model results for instream DO are within 1 mg/1 of instream standard at full permitted flow; 2) to
verify model predictions for outfall diffuser; 3) to provide data for future TMDL; 4) based on other
instream concerns. Instream monitoring may be conducted by the Permittee, and there are also
Monitoring Coalitions established in several basins that conduct instream sampling for the Permittee (in
which case instream monitoring is waived in the permit as long as coalition membership is maintained).
If applicable, summarize any instream data and what instream monitoring will be proposed for this
permit action: During the 2009 permit renewal, instream monitoring requirements were removed from
the permit, noting that:
• No effluent-instream impact was perceived,
• The Town's downstream sampling location had been relocated to a safer location that was 9.7
miles downstream and not considered demonstrative of the impact,
• Discussions with the Ambient Monitoring Unit indicated that AMS stations existed in the same
location as the Town's upstream sampling location and roughly 18 miles downstream from the
facility (AMS I5690000 and I6410000, respectively), and
• There are no other permitted discharges in this segment of the Lumber River.
Page 3 of 12

As the instream monitoring requirements were removed, Special Condition A.(6) Instream
Monitoring Reopener was added to allow for instream monitoring requirements to be added back into
the permit at the Division's discretion in the event that:
1. This segment of the Lumber River becomes impaired for a pollutant, known or suspected to be
present in the effluent discharge, or
2. There is an impact to the Lumber River Basin requiring data to define the impact, or
3. There are changes in the State Lumber River Ambient Monitoring programs at Broadman and
Fair Bluff
AMS station data was observed from January 2017 to March 2020. The data has been summarized in
Table 2 below.

As the AMS stations are so far apart, no statistical analysis was performed to determine upstream -
downstream relationships.
Per the 2016 implementation of instream dissolved metals standards, facilities with pretreatment
programs shall sample for total hardness in the effluent and upstream of the facility. As such, upstream
and effluent hardness sampling has been added to the permit at a quarterly frequency.
Is this facility a member of a Monitoring Coalition with waived instream monitoring (Y/N): NO
Name of Monitoring Coalition: NA
5. Compliance Summary
Summarize the compliance record with permit effluent limits (past 5 years): From August 2017 through
August 2022, the facility received 2 monthly average flow violations that resulted in NOVs (December
2018 and February 2020).
Summarize the compliance record with aquatic toxicity test limits and any second species test results
(past 5 years): The facility passed 18 of 18 quarterly chronic toxicity tests, as well as all 4 second species
chronic toxicity tests.
Summarize the results from the most recent compliance inspection: The last facility inspection conducted
in June 2021 reported that the facility was in compliance with NPDES permit NC0086550.

6. Water Quality -Based Effluent Limitations (WQBELs)
Dilution and Mixing Zones
In accordance with 15A NCAC 2B.0206, the following streamflows are used for dilution considerations
for development of WQBELs: 1Q10 streamflow (acute Aquatic Life); 7Q10 streamflow (chronic Aquatic
Life; non -carcinogen HH); 30Q2 streamflow (aesthetics); annual average flow (carcinogen, HH).
If applicable, describe any other dilution factors considered (e.g., based on CORMIX model results): NA
If applicable, describe any mixing zones established in accordance with 15A NCAC 2B. 0204(b): NA
Oxygen -Consuming Waste Limitations
Limitations for oxygen -consuming waste (e.g., BOD) are generally based on water quality modeling to
ensure protection of the instream dissolved oxygen (DO) water quality standard. Secondary TBEL limits
(e.g., BOD= 30 mg/1 for Municipals) may be appropriate if deemed more stringent based on dilution and
model results.
If permit limits are more stringent than TBELs, describe how limits were developed: Current limitations
for BOD were established in the 1999 renewal in accordance with the DWQ (now DWR) management
strategy for oxygen -consuming wastes in the Lumber River Basin; these limits are MA 15 mg/L and WA
22.5 mg/L. No changes are proposed from the previous permit limits.
Ammonia and Total Residual Chlorine Limitations
Limitations for ammonia are based on protection of aquatic life utilizing an ammonia chronic criterion of
1.0 mg/1 (summer) and 1.8 mg/1 (winter). Acute ammonia limits are derived from chronic criteria,
utilizing a multiplication factor of 3 for Municipals and a multiplication factor of 5 for Non -Municipals.
Limitations for Total Residual Chlorine (TRC) are based on the NC water quality standard for protection
of aquatic life (17 ug/1) and capped at 28 ug/1 (acute impacts). Due to analytical issues, all TRC values
reported below 50 ug/1 are considered compliant with their permit limit.
Describe any proposed changes to ammonia and/or TRC limits for this permit renewal: Ammonia limits
were established in the 1999 permit renewal in accordance with the DWQ (now DWR) management
strategy for oxygen -consuming wastes in the Lumber River Basin; these limits are MA 4.0 mg/L and WA
12 mg/L. As these limits are more stringent than those calculated based on ammonia toxicity (see attached
WLA sheet), there are no proposed changes. The TRC limit was also implemented during the 1999 permit
renewal as 28.0 ug/L. No changes are proposed.
Reasonable Potential Analysis (RPA) for Toxicants
If applicable, conduct RPA analysis and complete information below.
The need for toxicant limits is based upon a demonstration of reasonable potential to exceed water quality
standards, a statistical evaluation that is conducted during every permit renewal utilizing the most recent
effluent data for each outfall. The RPA is conducted in accordance with 40 CFR 122.44 (d) (i). The NC
RPA procedure utilizes the following: 1) 95% Confidence Level/95% Probability; 2) assumption of zero
background; 3) use of detection limit for "less than" values; and 4) streamflows used for dilution
Page 5 of 12

consideration based on 15A NCAC 2B.0206. Effective April 6, 2016, NC began implementation of
dissolved metals criteria in the RPA process in accordance with guidance titled NPDES Implementation of
Instream Dissolved Metals Standards, dated June 10, 2016.
A reasonable potential analysis was conducted on effluent toxicant data collected between January 2018
and May 2022. Pollutants of concern included toxicants with positive detections and associated water
quality standards/criteria. Based on this analysis, the following permitting actions are proposed for this
permit:
• Effluent Limit with Monitoring. The following parameters will receive a water quality -based
effluent limit (WQBEL) since they demonstrated a reasonable potential to exceed applicable
water quality standards/criteria: None
• Monitoring Only. The following parameters will receive a monitor -only requirement since they
did not demonstrate reasonable potential to exceed applicable water quality standards/criteria,
but the maximum predicted concentration was >50% of the allowable concentration: None
• No Limit or Monitoring: The following parameters will not receive a limit or monitoring, since
they did not demonstrate reasonable potential to exceed applicable water quality
standards/criteria and the maximum predicted concentration was <50% of the allowable
concentration: Copper, Zinc
• POTW Effluent Pollutant Scan Review: Three effluent pollutant scans were evaluated for
additional pollutants of concern. (2016, 2017, 2018)
o The following parameter(s) will receive a water quality -based effluent limit (WQBEL)
with monitoring, since as part of a limited data set, two samples exceeded the allowable
discharge concentration: None
o The following parameter(s) will receive a monitor -only requirement, since as part of a
limited data set, one sample exceeded the allowable discharge concentration: None
o The following parameters will not receive a limit or monitoring, since as part of a limited
data set, they did not demonstrate reasonable potential to exceed applicable water quality
standards/criteria and the maximum predicted concentration was <50% of the allowable
concentration: Arsenic, Beryllium, Cadmium, Total Phenolic Compounds, Total
Chromium, Cyanide, Lead, Nickel, Selenium, Silver
*Note: Total Silver was reported as <5 ug/1. The permittee shall report to the lowest PQL (<1 ug/1).
Based on the results of the RPA showing no reasonable potential for copper and zinc to exceed water
quality standards, quarterly monitoring for copper and zinc has been removed from the permit.
Attached are the RPA results as well as a copy of the Dissolved Metals Implementation Fact Sheet for
freshwater/saltwater to this Fact Sheet.
Toxicity Testing Limitations
Permit limits and monitoring requirements for Whole Effluent Toxicity (WET) have been established in
accordance with Division guidance (per WET Memo, 8/2/1999). Per WET guidance, all NPDES permits
issued to Major facilities or any facility discharging "complex" wastewater (contains anything other than
domestic waste) will contain appropriate WET limits and monitoring requirements, with several
exceptions. The State has received prior EPA approval to use an Alternative WET Test Procedure in
NPDES permits, using single concentration screening tests, with multiple dilution follow-up upon a test
failure.
Describe proposed toxicity test requirement: This is a Major POTW, and a chronic WET limit at 2.2%
effluent will continue on a quarterly frequency during the months of February, May, August, and
November.

Mercury Statewide TMDL Evaluation
There is a statewide TMDL for mercury approved by EPA in 2012. The TMDL target was to comply
with EPA's mercury fish tissue criteria (0.3 mg/kg) for human health protection. The TMDL established a
wasteload allocation for point sources of 37 kg/year (81 lb/year), and is applicable to municipals and
industrial facilities with known mercury discharges. Given the small contribution of mercury from point
sources (-2% of total load), the TMDL emphasizes mercury minimization plans (MMPs) for point source
control. Municipal facilities > 2 MGD and discharging quantifiable levels of mercury (>1 ng/1) will
receive an MMP requirement. Industrials are evaluated on a case -by -case basis, depending if mercury is a
pollutant of concern. Effluent limits may also be added if annual average effluent concentrations exceed
the WQBEL value (based on the NC WQS of 12 ng/1) and/or if any individual value exceeds a TBEL
value of 47 ng/1

Describe proposed permit actions based on mercury evaluation: For the previous permit cycle, mercury
monitoring is only required in the 3 effluent pollutant scans (2016, 2017, 2018). Analytical method 245.1
was used, so all values were reported as <200 ng/L. No limit has been added to the permit. However, the
Permittee shall sample for mercury using EPA Method 1631E, including when conducting effluent
pollutant scans. The facility was required to complete a mercury minimization plan in the 2015 renewal,
which was submitted as part of this renewal. As the facility is < 2 MGD in capacity, the MMP is removed
for this permit cycle.
Other TMDL/Nutrient Management Strategy Considerations
If applicable, describe any other TMDLs/Nutrient Management Strategies and their implementation
within this permit: N/A
Other WQBEL Considerations
If applicable, describe any other parameters of concern evaluated for WQBELs: As required by Session
Law 2018-5, Senate Bill 99, Section 13.1(r), every applicant shall submit documentation of any additional
pollutants for which there are certified methods with the permit application if their discharge is
anticipated. The list of pollutants may be found in 40 CFR Part 136, which is incorporated by reference. If
there are additional pollutants with certified methods to be reported, please submit the Chemical
Addendum to NPDES Application table with your application and, if applicable, list the selected certified
analytical method used. If there are no additional pollutants to report, this form is not required to be
included with your application. This requirement applies to all NPDES facilities. The Chemical
Addendum to NPDES Application will be required for any type of facility with an NPDES permit,
depending on whether those types of pollutants are found in your wastewater. The Town of Fairmont
informed the Division that no monitoring for additional pollutants has been conducted (see attached
chemical addendum) and therefore no additional pollutants of concern have been identified.

If applicable, describe any special actions (HQW or ORW) this receiving stream and classification shall
comply with in order to protect the designated waterbody: NA
If applicable, describe any compliance schedules proposed for this permit renewal in accordance with
15A NCAC 2H.0107(c)(2)(B), 40CFR 122.47, and EPA May 2007 Memo: NA
If applicable, describe any water quality standards variances proposed in accordance with NCGS 143-
215.3(e) and 15A NCAC 2B. 0226 for this permit renewal: NA
7. Technology -Based Effluent Limitations (TBELs)
Municipals
Are concentration limits in the permit at least as stringent as secondary treatment requirements (30 mg/l
BOD5/TSS for Monthly Average, and 45 mg/l for BOD5/TSS for Weekly Average). YES
If NO, provide a justification for alternative limitations (e.g., waste stabilization pond). NA
Are 85% removal requirements for BOD5/TSS included in the permit? YES, Overall BOD5 and TSS
removal rates were greater than 85%; removal rate dipped below 85% for BOD and TSS for individual
months — See attached BOD/TSS removal rate calculations
If NO, provide a justification (e.g., waste stabilization pond). NA
8. Antidegradation Review (New/Expanding Discharge):
The objective of an antidegradation review is to ensure that a new or increased pollutant loading will not
degrade water quality. Permitting actions for new or expanding discharges require an antidegradation
review in accordance with 15A NCAC 2B.0201. Each applicant for a new/expanding NPDES permit
must document an effort to consider non -discharge alternatives per 15A NCAC 2H.0105( c)(2). In all
cases, existing instream water uses and the level of water quality necessary to protect the existing use is
maintained and protected.
If applicable, describe the results of the antidegradation review, including the Engineering Alternatives
Analysis (EAA) and any water quality modeling results: NA
9. Antibacksliding Review:
Sections 402(o)(2) and 303(d)(4) of the CWA and federal regulations at 40 CFR 122.44(1) prohibit
backsliding of effluent limitations in NPDES permits. These provisions require effluent limitations in a
reissued permit to be as stringent as those in the previous permit, with some exceptions where limitations
may be relaxed (e.g., based on new information, increases in production may warrant less stringent TBEL
limits, or WQBELs may be less stringent based on updated RPA or dilution).
Are any effluent limitations less stringent than previous permit (YES/NO): NO
If YES, confirm that antibacksliding provisions are not violated: NA
Page 8 of 12

10. Monitoring Requirements
Monitoring frequencies for NPDES permitting are established in accordance with the following
regulations and guidance: 1) State Regulation for Surface Water Monitoring, 15A NCAC 2B.0500; 2)
NPDES Guidance, Monitoring Frequency for Toxic Substances (7/15/2010 Memo); 3) NPDES Guidance,
Reduced Monitoring Frequencies for Facilities with Superior Compliance (10/22/2012 Memo); 4) Best
Professional Judgement (BPJ). Per US EPA (Interim Guidance, 1996), monitoring requirements are not
considered effluent limitations under Section 402(o) of the Clean Water Act, and therefore anti -
backsliding prohibitions would not be triggered by reductions in monitoring frequencies.
For instream monitoring, refer to Section 4.
The Town of Fairmont was granted 2/week monitoring for BOD, ammonia, TSS and fecal coliform based
on 2012 DWR Guidance Regarding the Reduction of Monitoring Frequencies in NPDES Permits for
Exceptionally Performing Facilities during their 2015 renewal. The Town has requested continuation of
this monitoring frequency reduction as part of their renewal application. The last three years of the
facility's data for these parameters have been reviewed in accordance with the criteria outlined in the
guidance. Based on this review, 2/week monitoring frequency has been maintained for BOD, ammonia,
TSS and fecal coliform at both flow tiers. Footnote 4 has been added to Section A. (1.): 2/week sampling
must occur on any two non-consecutive days during the calendar week.
With their renewal application, the Town requested removal of daily temperature monitoring. Per 15A
NCAC 02B .0508, Grade III water quality limited wastewater facilities discharging primarily domestic
waste shall monitor effluent temperature daily. Daily effluent temperature monitoring has been
maintained in the permit.
Per 15A NCAC 02B .0508, Grade III water quality limited wastewater facilities discharging primarily
domestic waste shall monitor effluent conductivity 3/Week. However, upon review of upstream and
downstream conductivity data and despite the significant distance between the two AMS stations,
conductivity does not appear to be greater at the downstream station than the upstream location. As such,
effluent conductivity monitoring has not been added to the permit at this time.
To identify PFAS contamination in waters classified as Water Supply (WS) waters, monitoring
requirements are to be implemented in permits with pretreatment programs that discharge to WS waters.
While there are no WS waters designated by the Division downstream of the discharge, the discharge
point is upstream of the border between North Carolina and South Carolina. To ensure PFAS
contamination does not cross State lines, and as the Fairmont Regional WWTP has a pretreatment
program, monitoring of PFAS chemicals will be added to the permit at a frequency of 2/year. Since an
EPA method for sampling and analyzing PFAS in wastewater is not currently available, the PFAS
sampling requirement in the Permit includes a compliance schedule which delays the effective date of this
requirement until the first full calendar quarter beginning 6 months after EPA has a final wastewater
method in 40 CFR136 published in the Federal Register. This date may be extended upon request and if
there are no NC -certified labs.
11. Electronic Reporting Requirements
The US EPA NPDES Electronic Reporting Rule was finalized on December 21, 2015. Effective
December 21, 2016, NPDES regulated facilities are required to submit Discharge Monitoring Reports
(DMRs) electronically. While NPDES regulated facilities would initially be required to submit additional
NPDES reports electronically effective December 21, 2020, EPA extended this deadline from December
21, 2020, to December 21, 2025. The current compliance date, effective January 4, 2021, was extended as
a final regulation change published in the November 2, 2020 Federal Register. This permit contains the
requirements for electronic reporting, consistent with Federal requirements.

Dissolved to Total Metal Calculator
Do NOT enter any data directly into this spreadsheet.
Enter data onto "Table 1" under the Input Sheet and enter
"Effluent Hardness" under the Data Sheet.
In accordance with 40 CFR 122.45 (c ), permits are, have and
must be written as total metals.
This calculator has been inserted into the RPA to calculate
Total Metal allowable allocations once Table 1 has been
completed (Input Sheet) and Effluent hardness has been
entered (Data Sheet).
1) Following the spreadsheet from left to right. First
the allowable allocations for the dissolved metals will
appear for all the metals listed once Table 1 is complete
and effluent hardness entered. Use a default value of 25
mg/L if no hardness data is available. Second,
the Dissolved Metal allocations are divided by the
Translators to determine the Total Metals that can be
allocated to the Permittee. These Total Metals values are
automatically inserted into Table 2 and are the allowable
Total Metal allocations determined for the Permittee prior
to allowing for dilution. See Input sheet Table 2. The final
acute and chronic values shown under the RPA sheet are
the Total Metal values listed in Table 2 divided by the acute
and chronic IWC, respectively.
2) The Translators used in the freshwater RPA are the
Partition Coefficients published by US EPA in 1984. They
are TSS dependent equations and can be found listed with
the WQS hardness dependent equations under the sheet
labeled Equations. A fixed TSS value of 10 mg/L is used to
calculate the Translator values.
3) Pretreatment Facilities - PERCS will need a copy of the
Dissolved to Total Metal Calculator spreadsheet and the
RPA sheet along with the Final Permit. Pretreatment
Facilities are required to renew their Headwords Analysis
after renewal of their permits. Since all their metal
allocations are likely to change PERCS needs to see any new
metal permit limits and the allowable allocations for the
dissolved metals to assess Maximum Allowable Headworks
Loading (MAHL) numbers for each metal based on the
Combined Hardness values used in the permit writers RPA
calculations.
4) For Cadmium, Lead, Nickel, Chromium and Beryllium, if all
the effluent sampling data for the last three to five years
shows the pollutant at concentrations less than the
Practical Quantitative Level (PQL), it is not likely a limit or
monitoring will be put in the permit. However, if the
estimated NPDES permit limit is less than the Practical
Quantitative Limit (particularly, Cadmium and Lead) and
the pollutant is believed to be present, to assess
compliance with the new standards and for future permit
limit development, monitoring for the pollutant will be
required. If the facility is monitoring for the pollutant in its
Pretreatment LTMP, no monitoring is needed in the permit.

General Information on the Reasonable Potential Analysis (RPA)
The RPA process itself did not change as the result of the new metals standards. However, application of
the dissolved and hardness -dependent standards requires additional consideration in order to establish the
numeric standard for each metal of concern of each individual discharge.
The hardness -based standards require some knowledge of the effluent and instream (upstream) hardness
and so must be calculated case -by -case for each discharge.
Metals limits must be expressed as `total recoverable' metals in accordance with 40 CFR 122.45(c). The
discharge -specific standards must be converted to the equivalent total values for use in the RPA
calculations. We will generally rely on default translator values developed for each metal (more on that
below), but it is also possible to consider case -specific translators developed in accordance with
established methodology.
RPA Permitting Guidance/WQBELs for Hardness -Dependent Metals - Freshwater
The RPA is designed to predict the maximum likely effluent concentrations for each metal of concern,
based on recent effluent data, and calculate the allowable effluent concentrations, based on applicable
standards and the critical low -flow values for the receiving stream.
If the maximum predicted value is greater than the maximum allowed value (chronic or acute), the
discharge has reasonable potential to exceed the standard, which warrants a permit limit in most cases. If
monitoring for a particular pollutant indicates that the pollutant is not present (i.e. consistently below
detection level), then the Division may remove the monitoring requirement in the reissued permit.
1. To perform a RPA on the Freshwater hardness -dependent metals the Permit Writer compiles the
following information:
• Critical low flow of the receiving stream, 7Q10 (the spreadsheet automatically calculates
the 1Q10 using the formula 1Q10 = 0.843 (s7Q10, cfs) 0.993
• Effluent hardness and upstream hardness, site -specific data is preferred
• Permitted flow
• Receiving stream classification
2. In order to establish the numeric standard for each hardness -dependent metal of concern and for
each individual discharge, the Permit Writer must first determine what effluent and instream
(upstream) hardness values to use in the equations.
The permit writer reviews DMR's, Effluent Pollutant Scans, and Toxicity Test results for any
hardness data and contacts the Permittee to see if any additional data is available for instream
hardness values, upstream of the discharge.
If no hardness data is available, the permit writer may choose to do an initial evaluation using a
default hardness of 25 mg/L (CaCO3 or (Ca + Mg)). Minimum and maximum limits on the
hardness value used for water quality calculations are 25 mg/L and 400 mg/L, respectively.
If the use of a default hardness value results in a hardness -dependent metal showing reasonable
potential, the permit writer contacts the Permittee and requests 5 site -specific effluent and
upstream hardness samples over a period of one week. The RPA is rerun using the new data.
Page 2 of 4

Permit No. NC0086550
The overall hardness value used in the water quality calculations is calculated as follows:
Combined Hardness (chronic)
= (Permitted Flow, cfs *Avg. Effluent Hardness, mg/L) + (s7Q10, cfs *Avg. Upstream Hardness, mg/L)
(Permitted Flow, cfs + s7Q10, cfs)
The Combined Hardness for acute is the same but the calculation uses the 1Q10 flow.
3. The permit writer converts the numeric standard for each metal of concern to a total recoverable
metal, using the EPA Default Partition Coefficients (DPCs) or site -specific translators, if any
have been developed using federally approved methodology.
EPA default partition coefficients or the "Fraction Dissolved" converts the value for
dissolved metal at laboratory conditions to total recoverable metal at in -stream
ambient conditions. This factor is calculated using the linear partition coefficients
found in The Metals Translator: Guidance for Calculating a Total Recoverable
Permit Limit from a Dissolved Criterion (EPA 823-B-96-007, June 1996) and the
equation:
Cdiss = 1
Ctotal 1 + { [Kpo] [SS(1
+1 [10 6]
Where:
ss = in -stream suspended solids concentration [mg/1], minimum of 10 mg/L used,
and
Kpo and a = constants that express the equilibrium relationship between dissolved
and adsorbed forms of metals. A list of constants used for each hardness -dependent
metal can also be found in the RPA program under a sheet labeled DPCs.
4. The numeric standard for each metal of concern is divided by the default partition coefficient (or
site -specific translator) to obtain a Total Recoverable Metal at ambient conditions.
In some cases, where an EPA default partition coefficient translator does not exist (ie. silver), the
dissolved numeric standard for each metal of concern is divided by the EPA conversion factor to
obtain a Total Recoverable Metal at ambient conditions. This method presumes that the metal is
dissolved to the same extent as it was during EPA's criteria development for metals. For more
information on conversion factors see the June, 1996 EPA Translator Guidance Document.
5. The RPA spreadsheet uses a mass balance equation to determine the total allowable concentration
(permit limits) for each pollutant using the following equation:
Ca = (s7Q10 + Qw) (Cwqs) — (s7Q10) (Cb)
Qw
Where: Ca = allowable effluent concentration (µg/L or mg/L)
Cwqs = NC Water Quality Standard or federal criteria (µg/L or mg/L)
Cb = background concentration: assume zero for all toxicants except NH3* (µg/L or mg/L)
Qw = permitted effluent flow (cfs, match s7Q10)
s7Q10 = summer low flow used to protect aquatic life from chronic toxicity and human
health through the consumption of water, fish, and shellfish from noncarcinogens (cfs)
* Discussions are on -going with EPA on how best to address background concentrations
Flows other than s7Q10 may be incorporated as applicable:
1Q10 = used in the equation to protect aquatic life from acute toxicity
Page 3 of 4

Permit No. NC0086550
QA = used in the equation to protect human health through the consumption of water,
fish, and shellfish from carcinogens
30Q2 = used in the equation to protect aesthetic quality
6. The permit writer enters the most recent 2-3 years of effluent data for each pollutant of concern.
Data entered must have been taken within four and one-half years prior to the date of the permit
application (40 CFR 122.21). The RPA spreadsheet estimates the 95th percentile upper
concentration of each pollutant. The Predicted Max concentrations are compared to the Total
allowable concentrations to determine if a permit limit is necessary. If the predicted max exceeds
the acute or chronic Total allowable concentrations, the discharge is considered to show
reasonable potential to violate the water quality standard, and a permit limit (Total allowable
concentration) is included in the permit in accordance with the U.S. EPA Technical Support
Document for Water Quality -Based Toxics Control published in 1991.
7. When appropriate, permit writers develop facility specific compliance schedules in accordance
with the EPA Headquarters Memo dated May 10, 2007 from James Hanlon to Alexis Strauss on
40 CFR 122.47 Compliance Schedule Requirements.
8. The Total Chromium NC WQS was removed and replaced with trivalent chromium and
hexavalent chromium Water Quality Standards. As a cost savings measure, total chromium data
results may be used as a conservative surrogate in cases where there are no analytical results
based on chromium III or VI. In these cases, the projected maximum concentration (95th %) for
total chromium will be compared against water quality standards for chromium III and
chromium VI.
9. Effluent hardness sampling and instream hardness sampling, upstream of the discharge, are
inserted into all permits with facilities monitoring for hardness -dependent metals to ensure the
accuracy of the permit limits and to build a more robust hardness dataset.

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
The facility grounds and laboratory were well -maintained and orderly. All records, including an ORC
log, were available at the time of the review and complete. The facility submitted a permit renewal
application in 2019 that is still awaiting approval. The annual compliance report was submitted on
time. A copy of the 2020 report was available for review. Some monitoring violations flagged in DMRs
before the inspection were corrected during the inspection. Review of bench sheets in the field
laboratory revealed several date inconsistencies but did not affect the accuracy of DMRs for the
associated months. The effluent flow meter was last calibrated in Sept. 2020. This year's calibration is
scheduled for late June 2021. The tubing in the influent composite sampler was in good condition and
the cabinet was within proper temperature at 4°C. The effluent composite sampler was struck by
lightning the night before the inspection. Samples were still being properly collected, but the
refrigeration unit on the cabinet was broken. Facility staff had temporarily rerouted the sampler to a
retired composite sampler with a working refrigerator. The facility's generator is manually tested
under load monthly and automatically tested weekly. The town is currently accepting bids for a
replacement generator.
The Division remains concerned about the high amount of biosolids present in the aeration basin.
Solid levels should be reduced to increase the capacity of the plant to accommodate high flows,
particularly during hurricane season. The probability of losing solids during high flows increases as
the amount of solids in the aeration basin increases. Relatedly, if the digester contains a high level of
solids then facility staff are unable to waste from the aeration basin. Sludge was in the process of
being collected during the inspection, but must occur with greater frequency. The town is strongly
encouraged to increase the solids handling budget to avoid permit violations and improve efficiency
at the facility.
Samples for permit compliance were collected at Outfall 001 from the Fairmont WWTP's 24-hour
composite equipment on June 10th, 2021. Parameters sampled were BOD, TSS, fecal coliform, and
nutrients (ammonia, NO2/NO3, TKN, TP). These samples were submitted to the Division of Water
Resources Laboratory in Raleigh, NC.

Sludge Management Plan
Town of Fairmont WWTP
NC0086550
The Town of Fairmont owns and operates a 1.75 MGD activated sludge wastewater treatment
plant. The operational goal is to maintain the mixed liquor suspended solids (MLSS) at the level
needed to produce a quality effluent. The excess MLSS is removed from the activated sludge
process by wasting the excess amount, on an as -needed basis, the solids handling portion of the
plant. The components are:
• Sludge Thickener
• Two Aerobic Digesters — 190,000 gallons each
• Sludge Holding Basin — 444,400 gallons
To maintain the proper MLSS level, excess mixed liquor is wasted thru the sludge thickener and
then into the aerobic digesters. The aerobic digesters use aerobic bacteria to break down the
sludge to stabilize and reduce the volume of sludge. The air is turned off occasionally to allow
the sludge to settle, leaving a fairly clear effluent on top that can be decanted back into the plant.
The aeration is turned back on and the process repeated until the sludge is properly stabilized.
The stabilized sludge is then transferred to the Sludge Holding Basin until final disposal.
The Town contracts to have the stabilized sludge dewatered and composted. If needed, the
sludge could also be land applied using a contractor.

MUNICIPAL MERCURY MINIMIZATION PLAN
FAIRMONT WASTEWATER TREATMENT PLANT
NPDES #NC0086550
November 18, 2015
SECTION I - PURPOSE
The purpose of this Mercury Minimization Plan ("MMP") is to describe best management
practices through which the Town of Fairmont (the Town) 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 guide the Town in its efforts to control mercury loadings discharged
into its Publicly -Owned Treatment Works (POTW) 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 treatment plant. The management practices summarized below may also help
control some of the mercury reaching our storm sewer system as well.
SECTION II — FACILITY DESCRIPTION
The Town operates a publicly owned treatment works (POTW), including a collection system and
wastewater treatment plant (WWTP), that serves the Town of Fairmont, North Carolina.
The WWTP is a 1.75 MGD treatment facility, utilizing the activated sludge process. The major
treatment process consists of: preliminary treatment, two aeration basins for biological treatment,
secondary clarifiers, disinfection, and solids handling. However, as with most municipal treatment
plants, the Town's WWTP is 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. 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.

SECTION III — PROGRAM PLAN
A. EVALUATION OF POTENTIAL NON -DOMESTIC SOURCES CONTRIBUTING
MERCURY TO THE POTW
Within 24 months from the NPDES required 180-day period for development of an MMP, , 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 may have contributed mercury loadings to the sewer system.
The Town will also survey and evaluate the following common sources of mercury in its service
area: (1) dentist offices; (2) hospitals; (3) laboratories; (4) auto recyclers; and (5) other potential
sources of mercury based on existing information.
The Town will also survey and evaluate the following common sources of mercury in its service
area: (1) dentist offices; (2) hospitals; (3) laboratories; (4) auto recyclers; and (5) other potential
sources of mercury based on existing information.
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.

Housekeeping, Spill 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 next two years 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.
Laboratory Practice
The Town operates a laboratory for purposes of complying with state and federal monitoring and
sampling requirements. The laboratory is a potential source of small quantities of mercury -
containing compounds. Laboratory employees will be trained in the proper handling and disposal
of these materials. The laboratories have also replaced mercury thermometers with non -mercury
thermometers, whenever practical.
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.

Town of Fairmont WWTP
Treatment Plant Narrative
NPDES #NC0086550
The Town of Fairmont WWTP is a wastewater treatment plant utilizing the activated sludge
process. The facility is permitted for 1.75 mgd and has an average daily flow of 0.76 mgd. The
facility receives wastewater flow from the Towns of Fairmont, Boardman, Fair Bluff, Proctorville,
and Cerro Gordo.
The WWTP consists of the following major units:
• Bar Screen
• Grit Removal
• Influent Pump Station
• Two Aeration Basins
• Two Clarifiers
• Two Chlorine Contact Chambers
• Cascade Aerator
• Gravity Thickener
• Two Aerobic Digesters
• Sludge Holding Basin
• Standby electrical generator
Preliminary Treatment
As the flow enters the facility it is screened. The physical process of wastewater treatment begins
with screening out large items that have found their way into the sewer system, and if not removed,
can damage pumps and impede water flow. After passing through the screens, the flow enters the
grit collector that is designed for the purpose of continuously removing settled non -organic grit.
Excessive sand entering the treatment process can cause excessive wear on pump parts, clog lines
and valves, and deposit on the bottom of the basins.
Secondary Treatment
From preliminary treatment the influent flows to the influent channel where it is mixed with the
Return Activated Sludge (RAS) from the final clarifiers. This mixture is directed by gravity flow
into one or both of the aeration basins. Each of the two (2) rectangular 350,000 gallon aeration
basins provide an environment for continued mixing of the wastewater and the RAS in an extended
aeration mode with long detention and solids retention times via 825 fine bubble air diffusers.
Water is discharged from the two aeration basins into the two secondary clarifiers. Quiescent
conditions in the clarifiers provide an environment for the separation of solids and water. The

settled activated sludge is returned to the oxidation ditches (Return Activated Sludge or RAS) to
increase the bacterial concentration, help in propagation, and accelerate the breakdown of organic
material. The RAS pump rate is set to maintain a sludge blanket of approximately three feet in the
clarifier. To maintain the proper amount of activated sludge in the oxidation ditch, a portion of
the settled sludge will be removed (Waste Activated Sludge or WAS) from the treatment process
by pumping a portion of the RAS to the sludge digester.
Disinfection
The clear effluent from the clarifiers flows to the adjacent chlorine contact basin. A chlorine
solution is added to the head of the basin and the basin provides the needed contact time for
disinfection. Dechlorination occurs at the discharge end of the contact basins. The disinfected
effluent is aerated using a cascade aerator. The cascade aerator is a series of concrete steps leading
from the chlorination/dechlorination basin to the 18" DIP that delivers the treated effluent to be
discharged.
Solids Handling
Wasted activated sludge is pumped to two aerobic digesters with a capacity of approximately
190,000 gallons each. The aerobic digesters provide long-term holding and stabilization of the
solids removed from the treatment process. Following the digestion process, the digesters are
alternately maintained in a quiescent state for a period of time to allow the sludge to settle. The
supernatant is decanted and returned to the sludge thickener overflow pipe. Stabilized sludge may
be stored in the sludge holding basin (444,000 gallons).
