*Based off of permitted flows.
Briefly describe the proposed permitting action and facility background: The Town of Cary has applied
for an NPDES permit renewal at 12.0 MGD for the North Cary WWTP. This facility serves a population
of approximately 89,400 residents in the Towns of Cary and Morrisville and RDU Airport, as well as 1
categorical industrial user (CIUs) via a Division -approved pretreatment program. Treated domestic and
industrial wastewater is discharged into Crabtree Creek, a class B; NSW waterbody in the Neuse River
Basin. Outfall 001 is approximately 26 miles upstream of waters designated as WS-V.
In addition to the NPDES permit, the Town operates facilities for bulk and reclaimed water distribution in
accordance with Non -Discharge Permit WQ0017923.
Sludge disposal: Sludge is currently hauled to the South Cary WRF biosolids dryer producing Class A
biosolids and a beneficial product for reuse as an agricultural fertilizer amendment.

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).
Is this facility a member of a Monitoring Coalition with waived instream monitoring (YIN): YES
Name of Monitoring Coalition: Lower Neuse River Basin Association
If applicable, summarize any instream data and what instream monitoring will be proposed for this
permit action: The current permit requires instream monitoring for temperature, dissolved oxygen, pH,
CBOD5, and NH3-N upstream at Old Reedy Creek Road and downstream at (D1) Ebenezer Church Road,
(D2) between US I and Lassiter Mill Dam and (D3) New Hope Road. As the permittee is a member of
the Lower Neuse River Basin Association (LNBA) instream monitoring requirements are provisionally
waived. The nearest upstream monitoring station is Ambient Monitoring System (AMS) station
J2850000, located just upstream of the outfall. The nearest downstream monitoring station is AMS station
J3000000, located approximately 5.3 miles downstream of the outfall. AMS data was also available for
fecal coliform, turbidity, conductivity, NO2+NO3, TKN, TP and TSS. Instream data from January 2018
through March 2020 has been summarized below in Table 2.

Students t-tests were run at a 95% confidence interval to analyze relationships between instream
samples. A statistically significant difference is determined when the t-test p-value result is < 0.05.
Downstream temperature was not greater than 32 degrees Celsius [per 15A NCAC 02B .0211 (18)]
during the period reviewed. Downstream temperature was not greater than upstream temperature by more
than 2.8 degrees Celsius during the period reviewed. It was concluded that no statistically significant
difference exists between upstream and downstream temperature.
Average downstream DO was above 5 mg/L [per 15A NCAC 02B .0211 (6)] during the period reviewed.
Downstream DO was not observed at levels less than 4.0 mg/L during the period reviewed. It was
concluded that no statistically significant difference exists between upstream and downstream DO.
It was concluded that a statistically significant difference exists between upstream and downstream
conductivity, with downstream conductivity generally being observed at levels higher than upstream
conductivity. As such, instream conductivity monitoring has been added.
Fecal coliform is not currently required in the permit. AMS fecal coliform data was reviewed, and it was
concluded that no statistically significant difference exists between upstream and downstream fecal
coliform. While downstream fecal coliform was observed at levels greater than 400/100mL on occasion,
these observances occurred concurrently with elevated upstream fecal coliform levels greater than
400/100mL. However, as the receiving stream is Class B, in accordance with DWR guidance regarding
instream fecal coliform monitoring, instream fecal coliform has been added to the permit.
Ambient pH was observed within the range of 6.0 to 9.0 standard units at both monitoring stations during
the period reviewed. It was concluded that no statistically significant difference exists between upstream
and downstream pH.
It was concluded that a statistically significant difference exists between upstream and downstream
turbidity, with downstream turbidity generally being observed at levels lower than upstream turbidity.
While downstream turbidity was observed at levels greater than 50 NTUs [per 15A NCAC 02B .0211
(21)] during the period reviewed on 1 occasion, this observance occurred concurrently with elevated
upstream turbidity levels greater than 50 NTUs.
Page 4 of 14

Insufficient downstream data points (2 samples) were available to conduct a statistical analysis for
instream TSS.
No upstream or downstream monitoring data was provided regarding CBOD5- While downstream
monitoring data was provided regarding NH3-N, TKN, NO2+NO3, and TP, no data was provided by the
upstream location. It is recommended that NH3-N, TKN, NO2+NO3, and TP be added to the suite of
parameters monitored at AMS station J2850000. As the receiving stream is classified NSW and the North
Cary WRF effluent is limited for Total Nitrogen and Total Phosphorous, instream monitoring for TKN,
NO2+NO3, and TP have been added to the permit. Instream monitoring for NH3-N has been maintained.
No instream data were available at either station for CBOD5. It is recommended that CBOD5 be added to
AMS stations J2850000 and J3000000.
5. Compliance Summary
Summarize the compliance record with permit effluent limits (past 5 years): The facility reported no limit
violations from June 2018 through June 2023.
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 from January 2019 to May 2023.
Summarize the results from the most recent compliance inspection: The last facility inspection conducted
in June 2023 reported that the facility was compliant.
6. Water Quality -Based Effluent Limitations (WQBELs)
Dilution and MixingZones
ones
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 CORMLY 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.
Ifpermit limits are more stringent than TBELs, describe how limits were developed: Limitations for
summer and winter CBOD5 are based on a 1991 intensive modeling analysis (Qual2E) performed by
HDR and reviewed and accepted by the Division with the September 12, 1994 Wasteload Allocation
(WLA). No changes are proposed.
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.
Page 5 of 14

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/l (acute impacts). Due to analytical issues, all TRC values
reported below 50 ug/l are considered compliant with their permit limit.
Describe any proposed changes to ammonia and/or TRC limits for this permit renewal: The permit does
not currently set limits or monitoring requirements for TRC due to the facility employing UV treatment
for disinfection. However, in the event of an emergency where chlorination is required as a backup or
temporary means of disinfection at the facility, a TRC limit and monitoring requirement have been added
to the permit based on the review in the attached WLA spreadsheet. Please note that TRC monitoring is
only required in the event that chlorine is used at the plant and as part of the regular Effluent Pollutant
Scans.
Limitations for summer and winter ammonia are based on a 1991 intensive modeling analysis (Qual2E)
performed by HDR and reviewed and accepted by the Division with the September 12, 1994 WLA and a
best professional judgement (BPJ) ammonia agreement with the Town. The ammonia limits have been
reviewed in the attached WLA for toxicity 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/z 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: None
• Monitoring. Only. nly. 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 Arsenic, Total Cadmium, Total Chromium, Total Copper, Total Cyanide,
Total Lead, Total Molybdenum, Total Nickel, Total Selenium, Total Silver, Total Zinc
• POTW Effluent Pollutant Scan Review: Three effluent pollutant scans (2020, 2021 and 2022)
and additional submitted data 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
Page 6 of 14

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
the maximum predicted concentration was <50% of the allowable concentration: Total
Beryllium, Total Phenolic Compounds, 1,4-dioxane (March 2022 — March 2023)
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: This is a Major POTW, and a chronic WET limit at 90%
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: 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 did not report quantifiable levels of mercury (> 1 ng/1) during the
period reviewed, the mercury minimization plan (MMP) special condition has been removed.
Other TMDL/Nutrient Management Strategy Considerations
If applicable, describe any other TMDLs/Nutrient Management Strategies and their implementation
within this permit: The Environmental Management Commission adopted Nutrient Management Strategy
Page 7 of 14

rules in December 1997, classifying the entire Neuse River Basin as Nutrient Sensitive Waters. The point
source rule [T15A NCAC 2B .0713 (previously .0234)] sets Total Nitrogen (TN) discharge limits for all
point source dischargers larger than 0.5 MGD.
The rule also allows dischargers to form a group compliance association and work together to reduce
nitrogen; this option allows the association members added flexibility in controlling nitrogen discharges.
At the same time, the association is subject to a group NPDES permit ensuring that the association and its
individual members are accountable if they exceed the applicable nitrogen limits. Under the rule, there are
three types of TN limit in the Neuse:
1. the individual limits in the dischargers' individual permits,
2. the aggregate limit in an association's group NPDES permit, and
3. the individual allocations/limits for each Association member, also in that association permit.
A discharger may be subject to the first type of limit, or to the second and third, but never to all three at
the same time. The discharger is first subject to the TN limit (if any) in its individual NPDES permit. If
becomes a co-permittee to a compliance association's group NPDES permit, it is then governed by the TN
limits in that permit. If the association complies with its group TN limit in a given year, all members are
deemed to be in compliance with their individual allocations/ limits in the group permit. If the association
exceeds its limit, the members then become subject to their individual allocations/ limits as well.
Regardless of which permit governs a TN discharge, allocations/ limits will likely change over time as the
dischargers purchase, sell, trade, lease, or otherwise transfer nitrogen allocations. The Division will
modify the affected permits as necessary to ensure that the limits are kept up to date and reflect any such
transactions.
Nitrogen: The permit includes nutrient limits consistent with the Nutrient Management Strategy rule. The
Permittee receives a TN Load limit of 143,246 lb/yr, a calendar year limit.

Note: Average reported flow from January 2019 - May 2023 approximately 51.7% of permitted flow.
The Permittee is a member of the Neuse River Compliance Association at this time. So long as it remains
a co-permittee member, it is deemed to be in compliance with the TN limit in this permit, and its TN
discharge is governed instead by the Association's group NPDES permit NCC00000I, first issued
December 30, 2002 and most recently renewed on December 12, 2018.
Phosphorus: The Permittee's 2.0 mg/L Total Phosphorus limit is carried forward in the new permit. It is a
quarterly average limit to conform with the rule requirements. The January 2019 through May 2023
quarterly average reported TP ranged from 0.18 to 0.48 mg/L.
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 I LI 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. In their application, the Town
provided the chemical addendum and informed the Division that additional sampling for 1,4-dioxane,
Page 8 of 14

Trichlorofluoromethane and fluoride had been conducted. These parameters were not detected during the
sampling events. In addition to the chemical addendum, the Town informed the Division of proactive
sampling efforts they have conducted for tracking PFAS compounds. The Town has conducted sampling
of the North Cary WRF influent, headworks (influent + recycled flow) and post -filtration. Analysis was
conducted using Modified EPA Method 537.1 and Isotope Dilution. The Town found the presence of
some PFAS compounds during each of the three sampling events. As the North Cary WRF is a major
facility discharging above WS-V waters, monitoring of PFAS 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 HAS 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 to allow time for
laboratories to attain certification. 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. 010 7(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 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
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: N/A

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.
The Town of Cary has requested continuation of 2/week monitoring for CBOD, ammonia, TSS and fecal
coliform based on 2012 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. Based on this
review, 2/week monitoring frequency has been applied for CBOD, ammonia, fecal coliform, and TSS.
The EPA 2012 Recreational Water Quality Criteria for Bacterial Indicators of Fecal Contamination
recommends states set bacteriological water quality standards for primary recreation freshwaters using
either the Escherichia coli or Enterococcus pathogenic indicators. North Carolina's current recreational
surface water quality standards for Class B (primary recreation) waters use the fecal coliform bacteria
group pathogenic indicator. The Division sent a letter to the Town of Cary on March 8, 2023 requesting
participation in an E. coli Study being conducted across the state. This study is being conducted to
evaluate the financial impacts of switching to an E. coli standard for all Class B freshwaters. The data will
inform the Regulatory Fiscal Note a required part of the rulemaking package. The study covers the 2023
Swim Season, April through August, and requires instream and effluent monitoring and reporting of fecal
coliform, E. coli, turbidity, temperature, DO, conductivity and pH. Additionally, instream sampling
events are to be accompanied by a concurrent precipitation recording. The Town has submitted data for
April and May, to date.
The current permit includes Special Condition A.(5.) Clarification of Compliance When a Permit Limit is
Set At or Below ML (Minimum Levels). Special Condition A.(5.) is based on the National Guidance for
the Permitting, Monitoring, and Enforcement of Water Quality -Based Effluent Limitations Set Below
Analytical Detection/Quantitation Levels:
(a.) The following definitions apply to this permit:
(i.) The Minimum Level (ML) is defined as the concentration in a sample that is equivalent to the
concentration of the lowest calibration standard analyzed by a specific analytical procedure.
(ii.) The Method Detection Limit (MDL) is defined as the minimum measured concentration of a
substance that can be reported with 99% confidence that the measured concentration is
distinguishable from method blank results.
(b.) Per 15A NCAC 213.0505 (e)(4)(B), all monitoring required for permit application or to determine
compliance with effluent limitations or applicable water quality standards shall be performed using
sufficiently sensitive methods. Per 40 CFR 122.2 1 (e)(3)(i), methods are considered sufficiently
sensitive when:
(i.) the method ML is at or below the level of the applicable water quality criterion for the
measured pollutant or pollutant parameter; or
Page 10 of 14

(ii.) The method ML is above the applicable water quality criterion, but the amount of the
pollutant or pollutant parameter in a facility's discharge is high enough that the method
detects and quantifies the level of the pollutant or pollutant parameter in the discharge; or
(iii.) The method has the lowest ML of the analytical methods approved under 40 CFR part 136 or
required under 40 CFR chapter I, subchapter N or O for the
measured pollutant or pollutant parameter.
(c.) If no approved methods are capable of achieving a detection level below the permit discharge
requirement (or allowable discharge concentration) the method with the lowest ML shall be used.
(d.) In cases where the permit limit for a parameter is set at or below the ML for that parameter as
defined above using a sufficiently sensitive analytical procedure available and the measurement for
that parameter is less than the ML, the permittee shall be considered to be in full compliance with
the permit if the value reported (less than ML) on the discharge monitoring report for that
parameter is less than the ML (i.e., "< ML").
As Special Condition A.(5.) merely describes the practice of the Division with regard to compliance for
parameters whose lowest practical quantitation level is greater than the facility's allowable discharge
concentration for said parameter, Special Condition A.(5.) has been removed from the permit.
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.

Mr. Nick Coco, P.E.
Department of Environmental Quality
Division of Water Resources
NPDES Municipal Permitting Unit
1617 Mail Service Center
Raleigh, NC 27699-1617
Subject: North Cary WRF Draft NPDES Permit (NC0048879) Comments
Dear Mr. Coco:
On August 16, 2023, Cary received the draft NPDES permit for the North Cary Water Reclamation
Facility (NC0048879). We appreciate the opportunity to review the draft permit, fact sheet, and
associated reasonable potential analyses (RPA). Cary respectfully submits the following
comments and requests for modification of the proposed draft permit.
NPDES Permit Cover Letter
1. Total Residual Chlorine (TRC) limits and monitoring requirement (4th bullet point, pg. 1).
Request: Remove TRC monitoring as chlorine addition is not listed or permitted for effluent
disinfection. Cary will continue to maintain a redundant UV disinfection system, spare parts,
service support, and emergency backup generators for our existing and approved method
for effluent disinfection. If chlorine addition is required with a future permit modification,
chlorine monitoring language can be added.
2. Special condition to monitor effluent PFAS (6th bullet point, pg. 1).
Request 1: Cary requests NC Division of Water Resources (NCDWR) acknowledge the role
of the State of North Carolina approval processes for laboratory procedures prior to
requiring reporting of PFAS sampling results.
Request 2: Remove language requiring increased monitoring frequency of PFAS for
significant industrial users (SIU). This language is vague and unclear. Increased monitoring
for PFAS for SIU should be based on a legitimate concern supported by wastewater
monitoring data or categorical industrial user classifications that are found to manufacture or
discharge PFAS compounds at levels that warrant increased monitoring. It is anticipated
that virtually all industrial and domestic uncontrollable wastewater discharges will contain
some level of PFAS detections, therefore with this condition for any new SIU, would trigger
increased monitoring requirements with little or no justification or value in monitoring.
Part ! A. 1. Effluent Limitations and Monitoring Re uirements (Page 3 of 14
1. Total Residual Chlorine (TRC) limits, monitoring requirement, and Footnote 5.

Request: Remove TRC monitoring requirements and footnote 5 as chlorine addition is not
listed or permitted for use in the effluent stream. If chlorine addition is required with future
permit modification, chlorine monitoring language can be added.
2. Footnote 3: "The monthly average effluent BOD5 and Total Suspended Solids
concentrations shall not exceed 15% of the respective influent value (85% removal)."
Request: Please correct the footnote to specify carbonaceous biochemical oxygen demand
(CBOD5) as permit limits specify CBOD5 not BOD5.
3. Footnote 4: "Twice per week sampling must occur on any two non-consecutive days
during the calendar week."
Request: Please confirm that week's consisting of holidays will not require two non-
consecutive day sampling if holiday prevents it.
4. Effluent Pollutant Scan monitoring requirement.
Request: Add a footnote that confirms there is no requirement to monitor for TRC if chlorine
disinfection is not used.
Part I, AR-) Instream Monitoring Requirements (Page 5 of 14)
1. Table header language: "Beginning on the effective date of this permit and lasting until
lasting until permit expiration, the Permittee shall perform instream sampling upstream
and downstream of Outfall 001 as specified below:"
Request: Remove duplicate language "lasting until."
2. Instream Monitoring Requirements table.
Request 1: Please add the Footnote 1 superscript to all monthly measurement frequencies
with exception to total hardness.
Request 2: Change the sample type for Total Nitrogen to "Calculated".
Request 3: Remove the sample location superscript "U10" for hardness — total as CaCO3
(mg/L)
3. Footnote 1 sentence: "Instream sampling requirements €ew are provisionally waived in
light of the permittee's participation in the Lower Neuse River Basins Association
(LNBA)."
Request: Remove the word "for" from the referenced sentence in Footnote 1.
Part I A. 4. Additional Monitoring Re uirements for Permit Renewal (Page 7 of 14
1. (a) Effluent Pollutant Scans TRC monitoring requirement.
Request: Add language that confirms there is no requirement to monitor for Total Residual
Chlorine if Chlorine disinfection is not used.
C►AR UTILITIES

Part I A. 9. PFAS Monitoring Re uirement (Page 11 of 14
Request 1: Cary requests NCDWR acknowledge the role of the State of North Carolina
approval processes for laboratory procedures prior to requiring reporting of PFAS sampling
results.
Request 2: Please remove language requiring increased monitoring frequency of PFAS for
significant industrial users (SIU). This language is vague and unclear. Increased monitoring
for PFAS for SIU should be based on a legitimate concern supported by wastewater
monitoring data or categorical industrial user classifications that are found to manufacture or
discharge PFAS compounds at levels that warrant increased monitoring. It is anticipated
that virtually all industrial and domestic uncontrollable wastewater discharges will contain
some level of PFAS detections, therefore with this condition for any new SIU, would trigger
increased monitoring requirements with little or no justification or value in monitoring.

Description of any proposed changed to ammonia and/or TRC limits for this permit
renewal sentence: "However, in the event of an emergency where chlorination is required
as a backup or temporary means of disinfection at the facility, a TRC limit and monitoring
requirement have been added to the permit based on the review of the attached WLA
spreadsheet. "
Comment: The NCWRF is not designed or approved to use chlorine for disinfection. Cary will
continue to maintain a dual -fully redundant ultra -violet (UV) disinfection system, spare parts,
service support, and emergency backup generators for our existing and approved method for
effluent disinfection. If chlorine addition is required with a future permit modification, chlorine
monitoring language can be added.

Request: Please correct all typos to reflect the correct Total Nitrogen allocation of 143,246
Ibs/year.
Comment: Cary's North Cary WRF has a permitted total nitrogen load of 143,246
pounds/year and is based on our current 12.0 MGD capacity needs. Both the future hydraulic
capacity and nitrogen allocation is very important for Cary's future growth projections. The
North Cary WRF total nitrogen allocation is in accordance with the NC Neuse Nutrient Strategy
and the Neuse River Compliance Association co-permittee NPDES Permit NC000001. Cary's
total nitrogen allocation is finite and even with our WRF currently meeting and exceeding the
limits of technology for nitrogen removal, any reduction would be very detrimental. Any
proposed reduction in future hydraulic capacity, transportation factor calculation, or nitrogen
allocation is extremely important for Cary and likewise any point source discharger in the
Neuse River Basin subject to the Neuse Nutrient Strategy.

North Cary WRF Fact Sheet Addendum NC0048879
Comments to the draft permit NC0048879, which was public noticed for 30-day comment period on
8/16/2023, were provided by the Town of Cary with several requests. No comments were received from
any other party. Individual comments by the Town and Division responses are provided below.
1. Total Residual Chlorine
a. Remove TRC monitoring as chlorine addition is not listed or permitted for effluent
disinfection. Cary will continue to maintain a redundant UV disinfection system, spare
parts, service support, and emergency backup generators for our existing and approved
method for effluent disinfection. If chlorine addition is required with a future permit
modification, chlorine monitoring language can be added.
Response: The inclusion of the requirement for total residual chlorine (TRC) monitoring
and limitation is only applicable if, in an emergency situation, the Town finds that the UV
system is inoperable and must employ chlorination as a means of disinfection. Opening
and modifying a permit to add the requirement to monitor for TRC would take a length
of time which is likely longer than the temporary chlorination activity. As such, the
Division has applied this requirement to take effect only under such activities where it is
necessary. This requirement is consistently applied to facilities in situations similar to the
North Cary WRF and has been maintained in the permit. The Division is not requesting
chlorine addition, but merely requiring the monitoring and limitation of total residual
chlorine in instances where chlorination is used.
b. Add language that confirms there is no requirement to monitorforTotal Residual Chlorine
if Chlorine disinfection is not used.
Response: Footnote 5 of Section A.(1.) has been revised to include language covering the
Effluent Pollutant Scan expectations for TRC.
2. PFAS Monitoring
a. Cary requests NC Division of Water Resources (NCDWR) acknowledge the role of the State
of North Carolina approval processes for laboratory procedures prior to requiring
reporting of PFAS sampling results.
Response: Language acknowledging the need for laboratories to become NC -certified in
the new method has been added to the Special Condition.
b. Remove language requiring increased monitoring frequency of PFAS for significant
industrial users (SIU). This language is vague and unclear. Increased monitoring for PFAS
for SIU should be based on a legitimate concern supported by wastewater monitoring
data or categorical industrial user classifications that are found to manufacture or
discharge PFAS compounds at levels that warrant increased monitoring. It is anticipated
that virtually all industrial and domestic uncontrollable wastewater discharges will
contain some level of PFAS detections, therefore with this condition for any new SIU,
would trigger increased monitoring requirements with little or no justification or value in
monitoring.
Response: As the Town of Cary does not anticipate a new industrial user with ties to the
manufacturing, use, or production of PFAS chemicals, the Special Condition language has
been revised to remove the increase of monitoring frequency to monthly from quarterly
based on the introduction of a new significant industrial user.

North Cary WRF Fact Sheet Addendum NC0048879
3. Section A.(1.) Footnotes
a. Please correct the footnote to specify carbonaceous biochemical oxygen demand
(CBODs) as permit limits specify CBODs not BODs.
Response: The footnote has been corrected.
b. Please confirm that week's consisting of holidays will not require two non-consecutive
day sampling if holiday prevents it.
Response: The Division requests that the Town make the effort to always conduct the
sampling on non-consecutive days. However, if this is not possible due to the timing of
holidays (calendar week only has two consecutive days remaining under holiday
circumstances), the Town will not be considered out of compliance with the requirement.
c. Add a footnote that confirms there is no requirement to monitor for TRC if chlorine
disinfection is not used.
Response: Footnote 5 now states, "The facility shall monitor TRC only if using chlorination
for disinfection."
4. Instream Monitorine Reauirements
a. Remove duplicate language "lasting until" from table header.
Response: The duplicate language has been removed.
b. Please add the Footnote 1 superscript to all monthly measurement frequencies with
exception to total hardness.
Response: The superscript has been appropriately applied.
c. Change the sample type for Total Nitrogen to "Calculated".
Response: The sample type has been corrected.
d. Remove the sample location superscript "U10" for hardness - total as CaCO3 (mg/Q.
Response: The superscript has been removed.
e. Remove the word "for" from the referenced sentence in Footnote 1.
Response: The word "for" has been removed.
5. Fact Sheet
a. Please change "aeration holding tanks" to "aerated holding tanks" in the Facility
Information Table Treatment Units.
Response: The information has been corrected.
b. The fact sheet states, "Four effluent pollutant scans (2020, 2021 and 2022) ... ". Cary
requests that "four" be changed to "three" to match the number of scans performed and
cited.
Response: The number of scans referenced has been corrected in the fact sheet.
c. Please correct all typos to reflect the correct Total Nitrogen allocation of 143,246 Ibs/year.
Response: The typos have been corrected.
d. The proposed change for Stream Sampling- Extreme Weather should be corrected to read
"Condition maintained; rearranged to Special Condition A.(8.)."
Response: The number of scans referenced has been corrected in the fact sheet.

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.

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. NCO048879
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. NC0048879
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)
On June 16, 2023, the DWR as conducted a compliance training inspection at the subject facility
attended by: Ori Tuvia, Octovis Henriquez, Douglas Dowden, Min Xiao, Anjali Orlando, Nick coco,
Fenton Brown and Kevin Fowler. The assistance of Jim Bridges and Jonathan Bulla was greatly
appreciated during the inspection. Observations during the inspection are summarized below, as well
as an inspection checklist is attached for your records. • The current permit expired February 28,
2023, the facility has submitted a permit renewal application in a timely manner and operates under
the expired permit. The facility is permitted to discharge at a rate of 12.0 MGO and consists of:
mechanical screening; influent pump station; grit and grease removal system; Nutrient removal
system consisting of anaerobic selectors, oxidation ditches, anoxic zones and reaeration zones;
secondary clarifiers; deep -bed sand filters; UV disinfection; cascade aeration; gravity belt thickeners;
aerated sludge holding tanks. During the inspection one of the three reactor basins, one of two UV
channels, and one of the three circular clarifiers were offline due to low flow. All online treatment units
appeared to be operating satisfactorily. • The facility is a WW-4 Wastewater Treatment Plant and is
staffed 24 hours/day 7 days a week. • Records Review: Discharge Monitoring Report records for
February 2022 and February 2023 were reviewed with lab bench sheets and no transcription errors
were noted. Chain of Custody forms are completed and kept on site. A daily operation log book is
maintained and kept on site. Records are maintained for at least three years.- The laboratory on site
is certified to analyze most permit parameters (lab cert. no. 107). Toxicity and Mercury are sent to
private labs for analysis. A cursory review of the laboratory was conducted and the laboratory
appeared to be properly operated. Field meter calibration records were reviewed.- Biosolids are
thickened and temporarily stored on site in aerated tanks. The sludge is hauled to the South Cary
WRF or Western Wake Regional WRF for aerobic digestion and thermal drying into Class A
residuals.- The facility discharges to Crabtree creek, Class B, Nutrient Sensitive Waters, in the
Neuse River basin. The right of way to the discharged point is maintained. The effluent was clear,
trace amount of foam was observed, which dissipated within 100 feet of the outfall. No visible impacts
were noted immediately downstream of the discharge point. It was noted that the receiving stream is
actually an unnamed tributary to Crabtree Creek (Outfall 001 is about 100 yards away from the main
channel of Crabtree Creek), the receiving stream of the facility will be revised when the permit is up
for renewal.

Subject: NPDES Permit NO. NCO048879 monitoring frequency reduction request
Dear Mr. Coco,
The Town of Cary would like to submit, for your further review, a request to continue reduced
monitoring frequency for C130D5, TSS, Ammonia, and Fecal Coliform.
The facility has no more than one civil penalty assessment for the permit limit violations
for each target parameter during the previous three years.
The North Cary Water Reclamation Facility (WRF) does not have any civil penalty
assessments for permit violations for any target parameters in the previous three-year
period.
Neither the permittee nor any of its employees have been convicted of criminal
violations of the Clean Water Act within the previous five years.
Neither the permittee nor any of the employees at the North Cary WRF have been
convicted in the last five years of criminal violations of the Clean Water Act.
3. The facility is not currently under an SOC for target parameter effluent limit
noncompliance.
The North Cary WRF is not under a special order by consent (SOC) for target
parameter effluent limit noncompliance.
4. The facility is not on the EPA's Quarterly Noncompliance Report for target parameter
limit violations.
The North Cary WRF is not on the EPA's Quarterly Noncompliance Report for target
parameter limit violations.
5. For BODs, C130D5, NH3-N and TSS, the three-year arithmetic mean of effluent data must
be less than fifty percent of the monthly average permit limit. For fecal coliform or
enterococci, the three-year geometric mean must be less than 50 percent of the
919.677.0850 1 carync.gov
PO Box 8005 Cary, NC 27512

monthly average permit limit. For parameters with summer and winter limits, an annual
arithmetic mean of the season limits may be used in the calculation.
The North Cary WRF effluent three-year arithmetic mean for CBODS, NH3-N, and TSS
is less than 50% of the monthly seasonally adjusted permit limit. The fecal coliform
three-year geometric mean is less than 50% of the monthly average permit limit.

9. Reduced effluent monitoring must not impair assessment of sensitive downstream uses,
such as endangered species.
The Town of Cary is not aware of any downstream use or assessment that would
prohibit the reduction in effluent monitoring for CBODS, TSS, NH3-N and Fecal
Coliform from a daily monitoring requirement.
In meeting the criteria in the NC DWQ Guidance Regarding the Reduction of Monitoring
Frequencies in NPDES Permits for Exceptionally Performing Facilities, the Town of Cary hereby
requests a continuation of reduced effluent monitoring frequency for CBODS, TSS, NH3-N, and
Fecal Coliform at the North Cary WRF.

Mr. Hayes,
This is a follow up email to our conversation this afternoon. We will be relocating our influent composite
sampler from our regional pump station to our headworks while we do maintenance work at our pump station. This
work will take approximately one week to complete and then the sampler will return to it's original location. We will
note this change as a comment in our May el)MR. Thank you for talking with me this afternoon and if anything changes
with this plan I will reach back out to you.

Subject: Cary — North Cary WRF (NC0048879) PFAS Wastewater Testing
Dear Mr. Coco,
The Town of Cary — North Cary Water Reclamation Facility (NCWRF) would like to provide the NC
Department of Environmental Quality information pertaining to per-polyfluoroalkyl substances (PFAS)
sampled for and analyzed using non -certified analytical methods. The enclosed PFAS data represents
wastewater treatment process monitoring that occurred during the period of calendar year 2020 to
present. We performed this additional monitoring to better understand the presence and occurrence of
PFAS at our water reclamation facility.
Information provided in the enclosed summary spreadsheet include the following sampling locations and
the sample identification abbreviations:
Influent — influent wastewater without any plant recycle.
Headworks (Inf + Rec) — influent wastewater combined with plant recycle streams such as filter
backwash and GBT filtrate.
Post Filter — sample taken upstream of ultraviolet light disinfection and cascade aeration.
We hope that this submittal is found to be useful as we all continue to evaluate the emerging PFAS
contaminants in NC. Please contact Jason Parker, NCWRF Laboratory Supervisor, by phone at 919-677-
0850 or by email at [e-mail] if there are any specific questions regarding this submittal.
Sincerely,
