Briefly describe the proposed permitting action and facility background: The Town of Burnsville has
applied for an NPDES permit renewal at 0.8 MGD for the Burnsville WWTP. This facility serves a
population of approximately 4,000 residents, as well as 1 non -categorical significant industrial users
(SIU: Altec Industries, Inc. - SIC 3713—Truck and Bus Bodies; 40 CFR 433 Categorical, Metal Finisher)
via a Division -approved pretreatment program. Treated domestic and industrial wastewater is discharged
into the Cane River, a class C; Tr waterbody in the French Broad River Basin. Outfall 001 is
approximately 32 miles upstream of the NC/Tenn state border.
In their application, the Town noted that the volume of daily I&I is unknown. The Town hired McGill
and Associates (McGill) to study I&I at the facility and McGill reported that as much as 64% of the flow
at the plant over a 1-year period may be due to I&I. The Town is working with McGill and DWR on an
Page 1 of 12

established SOC (SC21-003, signed 12/06/2021, attached) to complete necessary upgrades for I&I
mitigation. The Town identified multiple improvement projects to be completed in 2024 and 2026,
including refurbishing the sewer interceptors in both sides of the collection system, installing a new gear
drive, and upgrading the plant headworks, blower electric system and laboratory.
Sludge disposal: Sludge is currently dewatered and sent to the sludge compost facility (WQ0002834).

As described in the facility background section above, McGill conducted an I&I study on behalf of the
Town and reported that as much as 64% of the flow at the plant over a 1-year period may be due to I&I.
The Town is working with McGill and DWR to complete necessary upgrades for I&I mitigation as
required in SOC SC21-003. The Town has identified multiple improvement projects to be completed in
2024 and 2026, including refurbishing the sewer interceptors in both sides of the collection system,
installing a new gear drive, and upgrading the plant headworks, blower electric system and laboratory.
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/l 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: The current permit does not require instream monitoring; no data are available for review.
Instream monitoring for DO, Fecal Coliform, Temperature, Conductivity, Ammonia and pH was required
beginning June 2008 due to concerns of plant upsets, observed stream impacts and effluent violations.
Page 3 of 12

This increased monitoring was reverted in November 2008 after reviewed plant -submitted information
demonstrated three months of substantial compliance and significantly improved WWTP performance.
As the facility discharges into classified Trout waters, instream temperature monitoring has been added.
Instream monitoring for ammonia and pH has been added to the permit. Please see Ammonia and Total
Residual Chlorine Limitations for more information.
Upstream and downstream samples shall be grab samples collected 1/week. Weekly monitoring has been
deemed appropriate given the size of the discharge relative to the receiving stream. Instream sampling
shall be conducted at least 50 feet upstream of the discharge and at least 500 feet from the discharge.
The permit does require quarterly upstream hardness monitoring. The facility reported an average
upstream hardness of 16.0 mg/L (range 5.1 mg/L — 67.4 mg/L).
Is this facility a member of a Monitoring Coalition with waived instream monitoring (YIN): NO
Name of Monitoring Coalition: NA
5. Compliance Summary
Summarize the compliance record with permit effluent limits (past 5 years): The facility reported three
BOD limit violations and seven flow limit violations in 2020 resulting in enforcement. In 2023, the
facility reported one pH limit violation resulting in enforcement. The facility is currently under SOC
SC21-003 for improvements to the Town's collection system and WWTP.
Summarize the compliance record with aquatic toxicity test limits and any second species test results
(past 5 years): The facility passed 17 of 17 quarterly chronic toxicity tests as well as all 4 second species
chronic toxicity tests from March 2019 to March 2023.
Summarize the results from the most recent compliance inspection: The last facility inspection conducted
in December 2019 reported that the facility was compliant. In January 2020, the Asheville Regional
Office (ARO) was notified that draw -down of the 0.3 MGD contact stabilization unit for a planned repair
of the clarifier revealed non -repairable structural failure of the clarifier. This was verified by Burnsville's
consulting engineer: McGill Associates. The integrated nature of this train renders the entire train non -
operable and non -repairable. ARO verified the structural failure and discussed mitigation measures with
the Town. More on this technical support visitation may be found in the attached Inspection Report.
In their April 2023 through June 2023 Quarterly Report as part of SOC21-003, the Town notified the
Division of receipt of additional funding bringing the total funding for Burnsville WWTP improvements
to $8.85 million, as well as the completion of a contract with WithersRavenel as the Town's Engineering
Firm of choice for WWTP improvements. With the additional funding, the Town has altered the scope of
work for rehabilitation of the Burnsville WWTP to replace the existing 0.3 MGD contact stabilization unit
with a 0.5 MGD treatment unit instead of a 0.3 MGD unit. The new plan also includes rehabilitation of
the existing 0.5 MGD treatment unit.
The last pretreatment inspection conducted in January 2023 reported that the facility was compliant.
6. Water Quality -Based Effluent Limitations (WQBELs)
Dilution and Mixing
In accordance with 15A NCAC 213.0206, 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
Page 4 of 12

OUlgen-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.
Ifpermit limits are more stringent than TBELs, describe how limits were developed: The existing
limitations for BOD5 at TBELs and have existed in the permit since its inception in 1981. In 1996,
modeling was conducted to verify that the TBELs were appropriate as part of a wasteload allocation
prepared during the renewal process. No changes are proposed.
Note: The 1996 modeling verified no limit or monitoring requirement was necessary for dissolved
oxygen.
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: TRC limits have
been reviewed in the attached WLA and have been found to be protective. No changes are proposed.
The current permit does not set limitations for ammonia. Ammonia requirements have been reviewed in
the attached WLA for toxicity. Based on this review, a monthly average ammonia limit of 13.0 mg/L has
been proposed. A weekly average limit has been determined at a 3:1 ratio of weekly average to monthly
average, based on the 2002 Implementation Policy for Permits with Monthly Average NH3-N Limits. As
the weekly average limit for ammonia is greater than 35.0 mg/L, the weekly average limit has been
capped at 35.0 mg/L. Effluent data from January 2019 through March 2023 has been compared to the
proposed limitation in Figure 1 below.

Figure 1. Comparison of Monthly Average Limit to Effluent Data
Page 5 of 12

No violation of the proposed monthly average limit was observed and no individual sample was reported
at a concentration greater than the proposed weekly average limit during the period reviewed. As such, a
compliance schedule for total ammonia limits is not considered necessary.
Per the July 2022 U.S. Fish and Wildlife Service report on the Appalachian Elktoe, "the Cane River
formerly contained a functional subpopulation of Appalachian elktoe but following a chemical spill in
2008 associated with the Town of Burnsville Wastewater Treatment Plant near the upper end of
distribution for Appalachian elktoe in the Cane River, the population died off and has not recovered. The
wastewater plant has continued to have spills of raw sewage and equipment failures that likely contributes
to the lack of rebound in 11 the population. Gravel mining further up the river may also contribute to
limited recovery of this subpopulation. This subpopulation is currently part of reintroduction efforts by
the NCWRC, but the population viability remains in question due to habitat degradation." Future
evaluation of the recovery status of the endangered Appalachian elktoe may result in reassessment of
ammonia requirements outlined in permit NC0020290 for the Burnsville WWTP. To aid in future
assessments, instream monitoring for ammonia, pH and temperature has been added to the permit.
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
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 2019
and March 2023. 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: Total Silver (MA 0.97 ug/L, DM 4.18 ug/L)*
• 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: Total Copper, Total Lead, Oil and Grease
• POTW Effluent Pollutant Scan Review: Three effluent pollutant scans (2019, 2020, 2021) were
evaluated for additional pollutants of concern.
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 they did not
demonstrate reasonable potential to exceed applicable water quality standards/criteria and
Page 6 of 12

the maximum predicted concentration was <50% of the allowable concentration: Total
Arsenic, Total Beryllium, Total Cadmium, Total Phenolic Compounds, Total Cyanide,
Total Nickel, Total Selenium, Total Zinc
*Total Silver monitoring shall be conducted using a PQL < 1 ug/L.
The current permit sets limits and weekly monitoring for Oil and Grease. The facility reported 3
detections during the period reviewed, with the highest reported value of 15 mg/L occurring during the
2019 effluent pollutant scan. As only one detection was at a level at 50% of the chronic allowable
discharge concentration, the limits and monitoring requirements for Oil and Grease have been removed.
If applicable, attach a spreadsheet of the RPA results as well as a copy of the Dissolved Metals
Implementation Fact Sheet for freshwater/saltwater to this Fact Sheet. Include a printout of the RPA
Dissolved to Total Metal Calculator sheet if this is a Municipality with a Pretreatment Program.
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: A chronic WET limit at 6% effluent will continue on a
quarterly frequency.
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/l.

Describe proposed permit actions based on mercury evaluation: The Town had not conducted low level
mercury testing using EPA Method 1631E at the time the renewal application was submitted. Upon
Division request, the Town conducted 3 sampling events for low level mercury in July 2023. Since no
annual average mercury concentration exceeded the WQBEL, and no individual mercury sample
exceeded the TBEL, no mercury limit is required. Since the facility is < 2.0 MGD facility in capacity, no
mercury minimization plan (MMP) special condition is required.
Page 7 of 12

Other TMDL/Nutrient Management Strategy Considerations
If applicable, describe any other TMDLs/Nutrient Management Strategies and their implementation
within this permit: NA
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 via a Chemical Addendum to NPDES Application table. As an attachment to the permit
application, the Town 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.
The Burnsville WWTP received influent wastewater from 1 CIU which is a metal finisher (Altec
Industries, Inc.) Per request by the Division, the Town conducted 3 sampling events of their CIU per
week for a 2-week span, resulting in 6 total Altec Industries, Inc. samples. The samples were collected on
June 27, July 5, July 6, July 7, July 10, and July 11, 2023. All samples were reported as non -detect at < 2
µg/L. As the sole industry in the Town's pretreatment program reported no detectable levels of 1,4-
dioxane during their 2-week sampling event, 1,4-dioxane requirements have not been added to the permit
at this time.
As the Burnsville WWTP discharges approximately 32 miles upstream of the NC/Tenn state border,
monitoring of HAS chemicals will be added to the permit at a frequency of quarterly. 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 CFRI36 published in the Federal Register. This date may be extended upon request and if
there are no NC -certified labs.
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: As total silver demonstrated
reasonable potential to exceed the facility's allowable discharge concentration based on state surface
water standards, monthly average and daily maximum limits have been put in the permit for total silver.
After discussing the limits with the Permittee, the Permittee requested a schedule of compliance to
provide time to locate issues and come into compliance with the new limits. A 3-year compliance
schedule has also been put in the permit. Within 1 year of the permit's effective date, the Permittee shall
submit to DWR an Action Plan for Division approval, summarizing the strategy or actions to be taken to
achieve compliance with the total silver limitations. The plan will include specific dates for completion or
implementation of each action. Within 2 years of the permit's effective date, the Permittee shall submit a
report to the Division summarizing actions taken in accordance with the Action Plan. The Town shall
achieve compliance with total silver limitations within 3 years of the permit's effective date.
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
Page 8 of 12

7. Technology -Based Effluent Limitations (TBELs)
Municipals (if not applicable, delete and skip to Industrials)
Are concentration limits in the permit at least as stringent as secondary treatment requirements (30 mg/l
BODS/TSS for Monthly Average, and 45 mg/l for BODS/TSS for Weekly Average). YES
If NO, provide a justification for alternative limitations (e.g., waste stabilization pond). NA
Are 85% removal requirements for BOD51TSS included in the permit? YES; Overall removal of BOD
and TSS was > 85% during the period reviewed. However, removal rates for both parameters dropped
below 85% on occasion during the period reviewed, most notably in 2020.
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 213.0201. 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(l) 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): Yes
If YES, confirm that antibacksliding provisions are not violated: As only one detection was at a level at
50% of the chronic allowable discharge concentration, the limits and monitoring requirements for Oil and
Grease have been removed. Additionally, monitoring has been removed for total copper and total lead as
the reasonable potential analysis demonstrated no reasonable potential for excursions above copper and
lead surface water standards.
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 213.0500; 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.
Page 9 of 12

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.

NPDES Implementation of Instream Dissolved Metals Standards - Freshwater Standards
The NC 2007-2015 Water Quality Standard (WQS) Triennial Review was approved by the NC
Environmental Management Commission (EMC) on November 13, 2014. The US EPA subsequently
approved the WQS revisions on April 6, 2016, with some exceptions. Therefore, metal limits in draft
permits out to public notice after April 6, 2016 must be calculated to protect the new standards - as
approved.

3. Only the aquatic life standards listed above are expressed in dissolved form. Aquatic life
standards for Mercury and selenium are still expressed as Total Recoverable Metals due to
bioaccumulative concerns (as are all human health standards for all metals). It is still necessary
to evaluate total recoverable aquatic life and human health standards listed in 15A NCAC
2B.0200 (e.g., arsenic at 10 µg/1 for human health protection; cyanide at 5 µg/L and fluoride at
1.8 mg/L for aquatic life protection).

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/WOBELs 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.
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 1 Q 10 using the formula 1 Q 10 = 0.843 (s7Q 10, 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.

Permit No. NCO020290
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 + s7Q 10, cfs)
The Combined Hardness for acute is the same but the calculation uses the IQ 10 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 I + { [Kp.] [ss('+a)] [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 = (s7Q 10 + Qw) (Cwgs) — (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 s7Q 10)
s7Q 10 = 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 s7Q 10 may be incorporated as applicable:
IQ 10 = used in the equation to protect aquatic life from acute toxicity
Page 3 of 4

Permit No. NC0020290
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.
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)
Tim Heim of the Asheville Regional Office was notified on the afternoon of 30 January, 2020 that
draw -down of the 300kGPD contact stabilization train for a planned repair of the clarifier revealed
non -repairable structural failure of the clarifier. This was verified by Burnsville's consulting engineer:
McGill Associates. The integrated nature of this train renders the entire train non -operable and
non -repairable.
Tim Heim traveled to the facility on 31 January, 2020 and met with Jadd Brewer (ORC), Dylan Lundy
(Burnsville Public Works), Chad Prisk (Maintenance) to assess the situation. Structural failure of the
clarifier was verified, and mitigation measures were discussed. These included:
Removal of the remaining wastewater from the 300kGPD contact stabilization train to the remaining
500kGPD contact stabilization train for treatment and discharge.
Pumping the 300kGPD digester to the belt press for removal of solids.
Maintaining minimal sludge blanket in the 500kGPD contact stabilization train to reduce the potential
for loss of solids during hydraulic overloading.
Increase of disinfectant (and proportional de -chlorination) in the effluent by approximately 15%.
Use of the non -operating 300kGPD train as an equalization basin during rain events.
It is anticipated that the 500kGPD contact stabilization train may be able to meet permit limits during

Concerns about the structural integrity of the plant, and the need for repairs to the 300kGPD train

Comment: The 300kGPD contact stabilization unit clarifier is inoperable and non -repairable. The
design of this contact stabilization unit means this renders the entire train inoperable
and non -repairable. Primary cause is buckling of the interior secondary clarifier walls.

Failure within thirty (30) days of receipt of written demand to pay the penalties or challenge
them by a contested case petition pursuant to G.S. 150B-23, will be grounds for a collections
action, which the Attorney General is hereby authorized to initiate. The only issue in such an
action will be whether the thirty (30) days has elapsed.
5. In recognition of the rehabilitation work already completed, the Division is provisionally
waiving the existing sewer tap moratorium. So long as continued progress is made regarding
reduction of I&I, the tap moratorium will remain waived. The Division reserves the right to
reinstate the moratorium if conditions at the facility deteriorate_
6. The nature of the additional flows is such that the waste characteristics do not exceed those
generally associated with domestic waste or are pretreated to domestic strengths. Waste of
greater than normal domestic strength may be accepted if the parameter(s) that exceed normal
domestic strength wastewater are not those for which interim limitations have been developed
and it can be demonstrated to the satisfaction of the Director the additional waste will not
adversely affect the treatment efficiency of the treatment system for any modified parameter or
result in the violation of any other permit limitation. All new and proposed industrial waste
tributary to the system must be controlled using all needed mechanisms including but not limited
to adoption and implementation of industrial waste control and pretreatment ordinances. No
wastewater can be accepted which will add toxic pollutants in quantities not generally associated
with domestic wastewater characteristics, unless the acceptance of the additional wastewater can
be supported through appropriate analyses acceptable to the Director.
7. This SOC and any terms and conditions contained herein, hereby supersede any and all previous
Special Orders, Enforcement Compliance Schedule Letters, terms and conditions contained
therein issued in connection with Collection System Permit WQCS00143 and NPDES Permit
NC0020290. In the event of a Permit modification or renewal, requirements contained therein
shall supersede those contained in this SOC, except as modified and contained herein.
S. Any violation of the terms of this SOC, including paragraphs 2 (c) and 2 (e) above may, upon
the discretion of the Director, terminate paragraph five (5) of this Order.
9. Noncompliance with the terms of this SOC are subject to enforcement action in addition to the
above stipulations, including injunctive relief pursuant to G.S. 143-215.6(C).
10. The Town, upon signature of this SOC, will be expected to comply with all schedule dates,
terms, and conditions of this document.
11. This SOC shall expire 90 days after completion of the work listed above.

Dear Mayor Coletta:
The Division of Water Resources (hereby known as the Division) has determined that the
Town of Burnsville Wastewater Treatment Plant (WWTP) is unable to meet permit
requirements for proper operation and maintenance and is therefore unable to adequately
treat the volume of wastewater the facility is receiving. This determination is based upon
the findings from an on -site inspection of the WWTP conducted on January 31.
During the inspection January 31, 2020, Division personnel observed that the 300,000
gallon -per -day contact stabilization unit was completely inoperable due to structural
damage to the clarifier. It is understood from subsequent conversations with Town of
Burnsville staff and the town's consulting engineer, McGill Associates, that the unit cannot
be repaired. This unit includes essential treatment components for compliance with the
permit effluent limits and permit operations and maintenance requirements. Without this
treatment unit, the facility will be continually noncompliant with permit NC0020290.
Concerns about the need for repairs to the clarifier were noted in 2015 and 2019 DWR
inspections.

North Carolina General Statute §145-215.67(a) states, in part, that "no person subject to the
provision of NCGS 143-215.1, 143-215.108, or 143-214.109 shall cause or allow the
discharge of any wastes to a waste -disposal system in excess of the capacity of the disposal
system or of any wastes which the waste -disposal system cannot adequately treat." Should
these terms be violated, NCGS 143-215.67 states a moratorium can be imposed "on the
addition of waste to a treatment works" if the treatment works is not capable of adequately
treating additional waste.
Based upon the facts and determination noted above, the Town of Burnsville WWTP is
hereby placed on a moratorium prohibiting the introduction of aU additional waste to the
collection system tributary to the WWTP. Please note that the subject moratorium has
restrictions beyond those cited in the October 21, 2019 moratorium. This moratorium

Quarterly Status Report
Town of Burnsville Collection System
NPDES PERMIT NCO020290 and WQCS00143
Dear Mr. Davidson:
This Quarterly Report documents the Town of Burnsville Sewer Collection System compliance
activities during January, February and March 2023.
The Town has experienced no SSO's and the Pine Swamp treatment facility has operated within
permitted limits during the period of this quarterly report.
• Project 3b-OMC Pump Station Flow Reduction
The project to install an additional pump at the OMC Pump Station to divert between
50-70,000 GPD of flow to the EY Sewer District's treatment facility located East of
Burnsville has been completed. Yancey County has committed to obligating a portion of
their 2021 State Budget Infrastructure funding for the construction of force main to
connect. The Town previously secured engineering services for the design and bids for
the force main connection to the EYWSD collection system. We are awaiting design
information from the engineering firm McGill Associates. The collection system is has
just recently been completed. The County has also committed to obligate funding from
their above mentioned earmark for camera inspection, cleaning and inspection of
portions of the EY Sewer District's collection system and repairs and upgrades to the EY-
WWTP as were outlined in document sent to the County Manager dated April 20, 2022
from the ARO. The total amount allocated for these inspections and repairs will be $1.5
million. We are awaiting budget documents from the engineering firm for the county to
formally process these requests through the Division.
P.O. Box 97 • Burnsville, North Carolina 28714 • Phone [phone] FAX [phone] www.townofburnsville.org

• Project 4-Baker's Creek Pump Station Rehabilitation
The Engineering Report was submitted to the Division for review within the proper
timeline. The engineers have responded to comments and we are awaiting approval.
• Project 5-West Main Sewer Interceptor Improvements
The Design package was submitted to the Division's engineer on CDBG-1 projects in
October of 2022 and the same was returned the engineering firm in late January 2023
with comments and a request for additional information. The Town was required to
hold an additional public hearing to clarify the project area covered some areas of sewer
easement that left the public road right of way and crossed private property easements
and amend the narrative. The public hearing was held at the Town Council's regular
March 2, 2023 business meeting and the minutes will be approved and submitted with
the rest of the documentation after the April 6, 2023 meeting. Due to the approval delay
an extension was requested and approved until May 10, 2023 for Design and Bid
package approval.
• Project 7- Burnsville WWTP Improvements:
Funding for this project has now been increased to $8,850,000.00 after Yancey County
agreed to provide, from their State earmark, the additional $2.8 million in funding when
the Town's application for more grant funding from DWI was unsuccessful. The County
has contracted with WithersRavenel as the Engineering Firm. With additional funding
the new proposed scope of rehabilitation would include the addition of a new 0.5
treatment unit to be installed instead of a 0.3 unit. The plan includes rehabilitation of
the existing 0.5 treatment unit for an EQ basin and possibly pretreatment processing as
well. The Town is planning to apply to the CDBG-1 program for another $1 million in
funding for this project. The engineers and working on a new budget for that grant
request. The additional funding will allow for more updates and modernization at the
treatment facility.
Additional Projects:
• The Town in has secured grant funding through Yancey County from Dogwood Health
Trust for the GIS mapping of the sewer collection system. The sewer mapping project
was completed in late November 2022. Additionally the same funding source will be
used to complete an update of the 2016 AMP/CIP along with an infrastructure master
plan study to evaluate current conditions and capacity of all Town infrastructure and
future needs of both the Town and County. McGill and Associates is finishing updating
the Town's AMP/CIP plan and has begun work on the updating the SDF calculator. At a
joint meeting in early March McGill updated the Town and County on their progress. We
do not yet have a final completion date, but work is continuing to move forward and
Town staff approved final CIP project draft last week.
• The Engineering Report for the East Main Sewer Interceptor Improvements was
submitted to the Division and approval letters were received on March 20, 2023. The

engineers are moving forward with the design and bid package for this project within
the Division's timeline.
The Town Council is committed to improving and planning for future maintenance of the
collection and treatment systems. The Town looks forward to the forward progress of all these
projects as we move through the design phase and onto bidding and construction in
accordance with the Division's timelines.
