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: The current permit does not require instream monitoring. The Town of Boone was the sole
member of the New River Basin Coalition, which dissolved in 2019. The Division was notified on August
28, 2019. As such, only data from 2016 through 2018 were reviewed from NRBC station K2100000,
located downstream of the Jimmy Smith WWTP at US Highway 421 South.

Downstream temperature did not exceed 29 degrees during the period reviewed [per 15A NCAC 02B
.0211(18)]. As no upstream data was recorded, no data comparison could be made between downstream
temperature and natural water temperature.
Downstream DO was not less than 5.0 mg/L during the period reviewed [per 15A NCAC 02B .0211(6)].
Downstream fecal coliform did not exceed a geometric mean of 200/100mL, nor did it exceed 400/100mL
in greater than 20% of the samples taken during the period reviewed [per 15A NCAC 02B .0211(7)].
Page 3of11
While the facility is no longer a member of a monitoring coalition, instream sampling continues to be
conducted downstream of the discharge via the Division's Ambient Monitoring System. The AMS station
is the same as what was used by NRBC. Based on the downstream data review demonstrating no
concerns with regard to surface water standards, and considering the Division shall continue using AMS
to sample downstream of the facility, instream monitoring requirements have not been added at this time.
However, as the Division is implementing dissolved metals standards in all permits, per the 2016
revisions to State water quality standards, the NPDES Permitting Unit will need site -specific instream
hardness data, upstream of the discharge, for each facility monitoring these metals in order to calculate
permit limitations. The Jimmy Smith WWTP has a pretreatment program that monitors hardness -
dependent metals. Instream hardness sampling, upstream of the discharge, has been added to the permit at
a monitoring frequency of quarterly.
Is this facility a member of a Monitoring Coalition with waived instream monitoring (Y/N): N
Name of Monitoring Coalition: NA
5. Compliance Summary
Summarize the compliance record with permit effluent limits (past 5 years): The facility reported no limit
violations during the period reviewed.
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 4 of 4 second species
toxicity tests from March 2017 to April 2021.
Summarize the results from the most recent compliance inspection: The last facility inspection conducted
in May 2021 reported that the facility was compliant.
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 1SA 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: The existing BOD
limits are based on 15A NCAC 2B.0225(d)(4)(C) water quality standards for outstanding resource waters.
No changes are proposed from the previous permit limits.
Page 4 of 11
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: As the facility
uses UV disinfection and does not employ chlorination as a backup means of disinfection, the current
permit does not include requirements for TRC. However, TRC shall still be sampled when conducting
effluent pollutant scans. No changes are proposed for TRC.
The existing ammonia limits are based on 15A NCAC 2B.0225(d)(4)(C) water quality standards for
outstanding resource waters. The limits and have been reviewed in the attached WLA and have been
found to be protective. 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
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 May 2017
through April 2021. 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: NA
• 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: Total
Copper
• 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 Arsenic, Total Cadmium, Total Chromium, Total Lead, Total Nickel, Total
Selenium, Total Silver, Total Molybdenum, Total Zinc, Bis (2-ethylhexyl) phthalate
• POTW Effluent Pollutant Scan Review: Three effluent pollutant scans were evaluated for
additional pollutants of concern. (PPAs from 2018, 2019 and 2020)
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: N/A
Page 5 of 11
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:
Acrylonitrile
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
the maximum predicted concentration was <50% of the allowable concentration: NA
Note: Total Phenolic Compounds and Total Beryllium were not analyzed in the RPA because both
parameters were reported as non -detect in each of the Effluent Pollutant Scans. Additionally, bis (2-
ethylhexyl) phthalate was reported as detected at 10 ug/L in the DMRs on 4/24/2018 and 5/15/2018. The
Town has informed the Division that these were typographical errors and provided the lab sheets to
confirm this [See attached].
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: The permit requires quarterly chronic toxicity testing at
44% effluent concentration. No changes are proposed.
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:. 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 and reported quantifiable levels of mercury, a mercury
minimization plan (MMP) is required. The Town requested the removal of the MMP condition in their
renewal application. Based on the data, the Division will maintain the MMP requirement.
Other TMDL/Nutrient Management Strategy Considerations
If applicable, describe any other TMDLs/Nutrient Management Strategies and their implementation
within this permit: NA
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
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
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
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)
Page 7 of 11
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.
Currently, temperature and conductivity monitoring are not required. Per 15A NCAC 02B .0508, Grade
IV Water Quality Limited facilities shall monitor for temperature and conductivity on a daily basis. As
such, daily effluent temperature and conductivity monitoring has been added to the permit.
The Town of Boone requested monitoring frequency reductions for BOD5, Total Suspended Solids, NH3-
N and Fecal Coliform on June 2, 2021 based on DWR Guidance Regarding the Reduction of Monitoring
Frequencies in NPDES Permits for Exceptionally Performing Facilities. The last three years of the
facility's data for these parameters have been reviewed in accordance with the criteria outlined in the
guidance. The Division has decided to grant the 2/week monitoring frequency requirements for BOD5,
Total Suspended Solids, NH3-N and Fecal Coliform.
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.

13. Public Notice Schedule:
Permit to Public Notice: June 8, 2021
Per 15A NCAC 2H .0109 & .0111, The Division will receive comments for a period of 30 days following
the publication date of the public notice. Any request for a public hearing shall be submitted to the
Director within the 30 days comment period indicating the interest of the party filing such request and the
reasons why a hearing is warranted.
14. Fact Sheet Addendum (if applicable):
The draft was submitted to the Town of Boone, EPA Region IV, and the Division's Winston-
Salem Regional Office, Aquatic Toxicology Branch, Ecosystems Branch and Operator Certification
Program for review. The Division received comments from the Town of Boone on July 7, 2021 via email
which noted that the effluent conductivity monitoring that was meant to be added into the permit was not
included in the permit requirements outlined in Section A.(1.), and requested that Special Condition
A.(3.) Effluent Pollutant Scan include language that allows for the exclusion of total residual chlorine
monitoring for the facility, since it uses UV disinfection and has no chlorine backup. As the PPA scans
are the only sampling requirements that track chlorine in the effluent stream and it only occurs 3 times per
permit cycle, the condition has been maintained. No comments were received from any other party.
Were there any changes made since the Draft Permit was public noticed (Yes/No): YES
If Yes, list changes and their basis below:
• Per 15A NCAC 02B .0508, effluent conductivity monitoring has been added to Section A.(1.).

Hi Karen,
I hope all is well.
I've just finished final review of the NPDES permit and received feedback internally regarding the total residual chlorine
sampling required in the PPAs. Based on the internal discussion, I am unable to add language to waive the TRC sampling
required in the PPAs, even though no chlorine is used in the treatment works. The reasoning behind this is that, while
the treatment works is not adding chlorine to the wastewater, outside sources of chlorine may exist that would
otherwise not be tracked. As such, the condition language has been maintained and total residual chlorine will still need
to be sampled 3 times per permit cycle via the PPAs.
I just wanted to give you the heads up before we sent out the final permit.
Thanks and have a great day.

Hi Nick,
Thanks for providing that information. Our comment just includes the following items, which are being mentioned for the
sake of clarity for us:
Conductivity monitoring was not included in chart in section Al.
Please exclude total residual chlorine monitoring found in section A3 since it is not a required parameter for PPA at this
location as we only utilize UV sterilization at the plant.
The mailing address for PAR still indicates the PERCS Unit.
Best regards and happy fourth of July!

Hi Karen,
I apologize for the late reply here.
We would be looking at 12 samples over 3 years, under the quarterly monitoring regimen. Having samples over this
duration would provide a better understanding of longer term operation of the facility and instances of presence for the
parameters.
I believe, in the case of the MMP, it has more to do with the statewide TMDL.

Good morning!
Thanks for the response. That will help us make an appropriate comment.
1-got it
2-12 samples over what time period? Would the division accept 12 days of samples in one month? 12 in 12 weeks, etc?
3-got it
4-got it. Do all implementation strategies require EMC approval or is it because of the TMDL?

Hi Karen,
Thanks for reaching out.
1. Conductivity seems to have been overlooked in years past. 15A NCAC 02B .0508 notes that water quality limited
facilities with SIC 4952 that are Grave IV should be sampling for conductivity at a daily frequency. Since the
Jimmy Smith WWTP has industrial contribution, keeping track of conductivity is especially of interest.
2. Regarding acrylonitrile, after 12 samples have been collected, the Town may request a major modification to the
permit to have the Division conduct an RPA to assess the need for continued sampling. However, please note
that the RPA would not just cover acrylonitrile.
3. Footnote 2 of Table B. Effluent Parameters for All POTWs with a Flow Equal to or Greater Than 0.1 MGD in EPA
Form 2A states, "Facilities that do not use chlorine for disinfection, do not use chlorine elsewhere in the
treatment process, and have no reasonable potential to discharge chlorine in their effluent are not required to
report data for total residual chlorine." Since we adopted our list based off of this EPA requirement, you are
okay to continue reporting NA in your application and to continue not sampling for it in your PPA scans. As this
isn't expressly stated in the Effluent Pollutant Scan special condition as is, I will add language to the condition to
clarify that you do not need to conduct the TRC sampling if you do not use chlorine in your process.
4. The mercury TMDL is statewide, so I would be applying it regardless of the stream index. However, I appreciate
you letting me know about this so I can look more closely at that benthos listing. With regard to the letter, I have
been informed that we cannot implement this as it appears this implementation strategy was not presented to
or approved by the Environment Management Commission to date. As such, the MMP condition will be
maintained.
5. We are currently in the process of updating the Boiler Plate language to address this point and a few other
items.
Please feel free to follow up with me with any additional comments you may have regarding the permit.
Thanks and have a great day,

This isn't really our comment, but some questions in order that we can make a useful comment regarding Acrylonitrile and
the MMP and note corrections that may be needed for other items.
1-We noticed that conductivity monitoring was added in the cover letter, but not to section Al. Out of curiosity, was this
something that had just been overlooked in the past or is there now a concern about conductivity downstream from us
that made it necessary?
2-Is there information and/or data that we could submit to reduce monitoring frequency of acrylonitrile from section Al
ahead of the final permit being issued?
3-In section A3 total residual chlorine is listed as a required parameter, but we have not included it in the past since we
use only UV disinfection at the plant. Should we plan on adding this to our PPAs?
4-The fact sheet discussed the reasons for retaining the MMP requirement in A4, but we would like to bring the following
points up for further consideration.
• The 303d listing of 10-1-(3.5)a which was highlighted in the fact sheet is upstream of our plant. The next
downstream sampling site is 10-1-(3.5)band is not listed.
• The "End of 2018 Pretreatment Mailing" letter sent on December 13, 2018 allowed for consideration of removal
even when effluent mercury concentrations are not consistently below 1 ng/L. The letter has been attached to this
email and the information referenced is on the first page in item 2.
5-In the boiler plate, the mailing address for PAR still indicates PERCS Unit. Will this need updating?

Good morning!
Thanks for the response. That will help us make an appropriate comment.
1-got it
2-12 samples over what time period? Would the division accept 12 days of samples in one month? 12 in 12 weeks, etc?
3-got it
4-got it. Do all implementation strategies require EMC approval or is it because of the TMDL?
5-got it

Hi Karen,
Thanks for reaching out.
1. Conductivity seems to have been overlooked in years past. 15A NCAC 02B .0508 notes that water quality limited
facilities with SIC 4952 that are Grave IV should be sampling for conductivity at a daily frequency. Since the
Jimmy Smith WWTP has industrial contribution, keeping track of conductivity is especially of interest.
2. Regarding acrylonitrile, after 12 samples have been collected, the Town may request a major modification to the
permit to have the Division conduct an RPA to assess the need for continued sampling. However, please note
that the RPA would not just cover acrylonitrile.
3. Footnote 2 of Table B. Effluent Parameters for All POTWs with a Flow Equal to or Greater Than 0.1 MGD in EPA
Form 2A states, "Facilities that do not use chlorine for disinfection, do not use chlorine elsewhere in the
treatment process, and have no reasonable potential to discharge chlorine in their effluent are not required to
report data for total residual chlorine." Since we adopted our list based off of this EPA requirement, you are
okay to continue reporting NA in your application and to continue not sampling for it in your PPA scans. As this
isn't expressly stated in the Effluent Pollutant Scan special condition as is, I will add language to the condition to
clarify that you do not need to conduct the TRC sampling if you do not use chlorine in your process.
4. The mercury TMDL is statewide, so I would be applying it regardless of the stream index. However, I appreciate
you letting me know about this so I can look more closely at that benthos listing. With regard to the letter, I have
been informed that we cannot implement this as it appears this implementation strategy was not presented to
or approved by the Environment Management Commission to date. As such, the MMP condition will be
maintained.
5. We are currently in the process of updating the Boiler Plate language to address this point and a few other
items.
Please feel free to follow up with me with any additional comments you may have regarding the permit.
Thanks and have a great day,

This isn't really our comment, but some questions in order that we can make a useful comment regarding Acrylonitrile and
the MMP and note corrections that may be needed for other items.
1-We noticed that conductivity monitoring was added in the cover letter, but not to section Al. Out of curiosity, was this
something that had just been overlooked in the past or is there now a concern about conductivity downstream from us
that made it necessary?
2-Is there information and/or data that we could submit to reduce monitoring frequency of acrylonitrile from section Al
ahead of the final permit being issued?
3-In section A3 total residual chlorine is listed as a required parameter, but we have not included it in the past since we
use only UV disinfection at the plant. Should we plan on adding this to our PPAs?
4-The fact sheet discussed the reasons for retaining the MMP requirement in A4, but we would like to bring the following
points up for further consideration.
• The 303d listing of 10-1-(3.5)a which was highlighted in the fact sheet is upstream of our plant. The next
downstream sampling site is 10-1-(3.5)band is not listed.
• The "End of 2018 Pretreatment Mailing" letter sent on December 13, 2018 allowed for consideration of removal
even when effluent mercury concentrations are not consistently below 1 ng/L. The letter has been attached to this
email and the information referenced is on the first page in item 2.
5-In the boiler plate, the mailing address for PAR still indicates PERCS Unit. Will this need updating?

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 April6, 2016, with some exceptions. Therefore, metal limits in draft
permits out to public notice after April6, 2016 must be calculated to protect the new standards - as
approved.

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. NC0020621
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. NC0020621
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.

Subject: NC0020621 NPDES renewal —Request to reduce monitoring frequency
Dear Mr. Coco:
Town of Boone's Jimmy Smith WWTP effluent meets the criteria listed in DWQ's Guidance Regarding the
Reduction of Monitoring Frequencies in NPDES Permits for Exceptionally Performing Facilities. The
Town requests that consideration for reduced monitoring for the four target parameters (BOD5, TSS, NH3-
N and fecal coliform) be made during the permit renewal process.
• No civil penalty for permit limit violations for each target parameter during the previous three
years
• No permittee or employee has been convicted of criminal violations of the CWA during the
previous five years
• No SOC in place for target parameters at this facility
• Facility is not on EPA's quarterly noncompliance report for any target parameter limit violations
• Each target parameters' three-year arithmetic or geometric mean is less than 50% of the applicable
monthly average limit (see data provided)
• All target parameter daily sample data are below 200% the applicable monthly average limit
except two fecal coliform samples (see data provided)
• All target parameter daily sample data are below the applicable weekly average limit except one
fecal conform sample (see data provided)
• Reduced effluent monitoring is not anticipated to impair assessment of sensitive downstream uses
since the plant will continue to operate as it has previously and will likely continue to monitor at
the usual level during most of the year
Please contact me at 828/268-6250 or by email at rick.miller@townofboone.net, or Karen Reece at
828/268-6272 or by email at karen.reece@townofboone.net if you need more information.

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
Mr. Broschinski indicated that when plant was hydraulically upgraded, the digesters were not. So,
although they can handle their current sludge production in the aerated digisters, they may not be
able to in the future if their flows do increase.
Mr. Broschinski stated there is no backup disinfection system. He indicated they could not use
chlorine.
Mr. Broschinski stated they do NOT have an emergency contract with fuel vendor (priority status
during emergencies). Such an arrangement should be established.
