'Based on current permitted industrial flow: 0.25 MGD
Permitting Action: This Facility is owned by the Town of Mocksville operated and maintained by Envirolink Inc.
The Town applied for NPDES permit renewal and submitted a renewal application dated December 21, 2018,
received on January 2, 2019. The Dutchman Creek WWTP has a design capacity of 0.98 MGD and is currently
authorized to discharge 0.98 MGD into Dutchman Creek. The Facility serves about 5,100 customers within the
Town limits of Mocksville. The Facility's Pretreatment Program is active and has one Significant Industrial User
(SIU), a chicken processing plant, authorized to discharge 0.25 MGD [See attached Pollutants of Concern (POC)
review form and Allocation Table (AT) sheet for details].
Page 1 of 16

For the calendar year 2021 the total effluent flow averaged 0.47 MGD, 48% of the permitted flow. This Fact
Sheet assessment is based on a WWTP flow of 0.98 MGD.
Facility Background: The Facility was initially permitted in 1982. In 2005 the Facility transitioned from 0.68
MGD to 0.98 MGD. The Facility does not have current plans to expand but had significant upgrades since the
last NPDES permit renewal; therefore, the facility's components list has been updated. Inflow and infiltration
(I/I) were reported as 40.000 gpd in the NPDES renewal application.
Sludge disposal: The Facility land applies biosolids under Division permit WQ0003351. Currently, sludge and
solids produced at this facility are also pumped on an as -needed basis by EMA Resources. This typically occurs
every two to three months, depending on the accumulation of solids in the digester and weather conditions that
would prohibit solids from being disposed via land application.

' Stream flows taken from previous Fact Sheet (2014) per Division's guidelines
The WWTP is currently authorized to discharge via Outfall 001 into Dutchman Creek, at stream segment 12-
102-(2), classified as C water. The class denotes use as waters protected for uses such as aquatic life
propagation, survival and maintenance of biological integrity (including fishing and fish), wildlife, secondary
contact recreation, and agriculture. Yadkin River upstream of Dutchman Creek — at station Q2810000 is
impaired for turbidity. Basin Planning Division requests to apply this impairment to this stream segment and
therefore include effluent and instream monitoring for turbidity on the basis that the watershed is impaired for
turbidity.
The Outfall 001 is located about 100 feet from the Facility and about 5.5 miles upstream from the boundary of
the Yadkin River Water Supply Watershed.
Page 2of16

This permit may be reopened and modified to implement nutrient requirements in accordance with any future
TMDL and/or Nutrient Management Strategy (NMS) for the downstream water body, High Rock Lake. The
NMS development will commence upon the completion of North Carolina's nutrient -related water quality
criteria and in consultation with stakeholders in the watershed.

The data above was provided in the signed effluent pollutant scans/priority pollutant analysis (PPAs), Electronic
Discharge Monitoring Report (eDMR).
Sample results for the sampled constituents not included above such as arsenic, beryllium, cyanide, lead, and
selenium (among others sampled by the effluent pollutant scan/priority pollutant analysis (PPA)), were less
than the method detection level. The compounds in the above table were analyzed in the reasonable potential
analysis (RPA) and discussed below in the RPA section (Section 6.4) of this Fact Sheet.
As required by Session Law 2018-5, Senate Bill 99, Section 13.1(r), every applicant shall submit documentation
of any additional pollutants for which there are certified methods with the permit application if their discharge
is anticipated. If there are additional pollutants with certified methods to be reported, the permittee shall
submit the Chemical Addendum to NPDES Application table with their application and, if applicable, list the
selected certified analytical method used. If there are no additional pollutants to report, this form is not required
to be included with their application. This requirement applies to all NPDES facilities. Envirolink Inc.,
informed the Division via email that no monitoring for additional pollutants has been conducted (see email
exchange in attachments) and no additional pollutants of concern have been identified; therefore, with this
permit renewal, the Division is adding PFAS and 1,4 Dioxane monitoring requirements.
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 total maximum daily load (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): Y
Name of Monitoring Coalition: Yadkin Pee -Dee River Basin Association
Instream data summary and instream monitoring proposed for this permit action: The current permit requires
instream [upstream (U) and downstream (D)] monitoring for two parameters: DO, and Temperature. This permit
renewal proposes to include conductivity, and pH monitoring per 15A NCAC 02B .0508 and hardness per
the hardness -dependent dissolved metals water quality standards approved in 2016, instream hardness data is
needed for calculations of permit limitations. This permit is also including Nitrate, Nitrate, TKN, NH3, TN,
TP, and TSS. Since the downstream waters are Nutrient Sensitive Waters (NSW) and the Basin Planning Team
will need additional data to develop the TMDL. Turbidity is also added due to turbidity impairment in the
watershed.
Page 4 of 16

The upstream location in the current permit is set to be about 100 ft of the outfall, and the downstream location
is set to be about 0.5 miles of the outfall. However, since the Permittee is a member of the Yadkin Pee -Dee
River Basin Association, the downstream data is collected from station Q3105000, 0.9 miles downstream of
the discharge point. There is no near upstream station. The available instream data was obtained from the DWR
Water Sciences Section's Monitoring Coalition database for review.
The available data was reviewed from June 2017 through June 2022 and was compared with concurrent effluent
data, and against state water quality standards where applicable. Instream data review findings for each
parameter are summarized in the figures below.

Dissolved Oxygen (DO) -The downstream DO data is meeting the criteria for DO (per 15A NCAC 02B .0211
(6)), remaining not less than a daily average of 5.0 mg/l with an instantaneous value of not less than 4.0 mg/l.
Temperature - Reviewed instream temperature data showed seasonal patterns of summer highs and winter lows.
Summer temperature maxima at the station was at or below the water quality standard of 29°C for mountain
and upper piedmont waters (15A NCAC 02B .0211 (18)).
pH - Reviewed downstream and effluent pH data were between 5.8 and 8.7. The water quality standard shall
be between 6.0 and 9.0 standard units (15A NCAC 02B .0211 (14))
Total Phosphorous (TP), Total Nitrogen (TN), and ammonia - The permit does not currently require instream
monitoring for nutrients. The maximum TP effluent values within this permit cycle were detected in October
2017 and April 2018.
Fecal Coliform - Fecal Coliform is a parameter of concern for aquatic life and human health. The permit has
not required instream monitoring for Fecal Coliform, since the receiving stream is neither impaired for
coliform nor a Class B waterbody, per the 2002 guidance. Per review of the effluent monitoring report
violations data revealed that effluent fecal coliform exceeded 400 cfu/100 mL in 3% of the samples. Since the
Facility drains to the Yadkin River just upstream of High Rock Lake, which has had reported spikes of fecal
coliform (up to 8400 cfu/100 ml in 2019 and 4400 cfu/ml in 2021), with this permit renewal, the Division is
recommending the Facility to study the upstream, effluent, and downstream fecal concentrations to
demonstrate impacts to the Lake. No fecal monitor requirement has been added at this time.
The NPDES Permit requires upstream and downstream monitoring for this Facility. As stated above, the
Permittee has a membership with the Yadkin Pee -Dee River Basin Association (monitoring coalition). This
monitoring coalition currently only has a downstream monitoring station, and there is no upstream monitoring
station. To comply with the NPDES permit requirements, the Facility may coordinate with the monitoring
coalition the addition of an upstream monitoring station.

Summary of the compliance record with aquatic toxicity test limits and any second species test results (past S
years):
The facility passed 20 of 21 quarterly chronic toxicity tests from June 2017—July 2022. Failed the 2018 January
test and collected and passed the two consecutive samples. The Facility failed to provide the 4 second species
chronic toxicity tests with the NPDES permit application submittal. An extension for this submittal was made
and the results were submitted to the Aquatic Toxicology Branch on 10/2021, 1/2022, 4/2022, and 7/2022. All
the 4 second species tests passed.
Summary of the results from the most recent compliance inspection:
The most recent inspection (compliance evaluation), conducted 05/12/2022, found the facility without
compliance issues. The inspection report noted that the new secondary clarifiers were clean and operating
properly, and the facility appeared to be well operated and maintained. No discrepancies were noted during the
inspections. A pretreatment inspection was conducted on 8/1/2022 and similarly reported that records were well
organized, and the program is considered satisfactory. A note was made regarding their only SIU, a chicken
cooking and packaging facility, it has had repeated flow and BOD violations, for which the POTW had issued
Notices of Violation.

6. Water Quality -Based Effluent Limitations (WQBELs)
6.1 Dilution and MixingZones
ones
In accordance with 15A NCAC 213.0206, the following stream flows 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 I5A NCAC 2B. 0204(b): NA
6.2 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/l for Municipals) may be appropriate if deemed more stringent based on dilution and model
results.
Ifpermit limits are more stringent than TBELs, describe how limits were developed:
The current BOD limits were set from a level B model in 2005. The model predicted that the expanded waste
flow would require tertiary limits (BOD5= 5 mg/l, NH3=2 mg/l, DO = 6 mg/1) for the protection of the dissolved
oxygen standard in Dutchman Creek. No changes are proposed.
6.3 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/l (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/l (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:
The current ammonia limits were set from a level B model in 2005. The model predicted that the expanded
waste flow would require tertiary limits (BOD5= 5 mg/l, NH3=2 mg/l, DO = 6 mg/1) for the protection of the
dissolved oxygen standard in Dutchman Creek. The current TRC limit was first placed in the 2004 permit,
capped at 28 µg/L to protect the water quality standard of 17 µg/L.
Ammonia and TRC have been reviewed in the attached Wasteload Allocation (WLA) sheet. Current limits for
ammonia were found to be more stringent than the IWC-based calculated results in the WLA sheet. The
resulting TRC limit is capped at 28 µg/L and will be maintained in the permit.
6.4 Reasonable Potential Analvsis (RPA) for Toxicants
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
'/2 detection limit for "less than" values; and 4) stream flows used for dilution consideration based on 15A
NCAC 213.0206. Effective April 6, 2016, NC began implementation of dissolved metals criteria in the RPA
Page 8of16

process in accordance with guidance titled NPDES Implementation of Instream Dissolved Metals Standards,
dated June 10, 2016.
A reasonable potential analysis (RPA) was conducted on effluent toxicant data collected from the Permittee's
2021 effluent pollutant scans, DMRs from July 2017 to June 2022, and default upstream hardness. Pollutants
of concern included toxicants with positive detections and associated water quality standards/criteria. The data
set was limited for arsenic, beryllium, total phenolic compound, chromium, cyanide, lead, nickel, selenium,
dichlorobromomethane, methyl bromide, and chloroform. 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: copper and cadmium.
Copper was under quarterly monitoring in previous cycle.
Cadmium was limited in previous cycle. Cadmium limits were updated.
• 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: silver and zinc.
• 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: arsenic, chromium,
cyanide, lead, and selenium.
• These compounds will be monitored in the pretreatment program during this permit cycle:
• POTW Effluent Pollutant Scan Review: Three effluent pollutant scans sampled in 2021 were evaluated
for additional pollutants of concern.
o The following parameter(s) will receive a water quality -based effluent limit (WQBEL) with
monitoring since as part of a limited data set, two samples exceeded the allowable discharge
concentration: NA
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: Nickel
o The following parameters that showed detection will not receive a limit or monitoring, since
they did not demonstrate reasonable potential to exceed applicable water quality
standards/criteria: dichlorobromomethane, methyl bromide, chloroform, and chromium total.
RPA results, as well as a copy of the Dissolved Metals Implementation Fact Sheet for freshwater, are included
as attachments of this Fact Sheet.
6.5 Toxicity Testina 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: Dutchman WWTP is a Minor Publicly Owned Treatment Work
(POTW), discharging domestic and industrial wastewater with chronic WET limits of 37% effluent, monitored
quarterly using Ceriodaphnia dubia. Per 40 CFR 122.210)(5)(v), four -second species will continue to be
required as well.
Page 9of16

6.6 Mercury Statewide Total Maximum Daily Load (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 multiple quantifiable levels of mercury (>1 ng/1) received 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
A mercury evaluation was conducted in accordance with the Permitting Guidance developed for the
implementation of the statewide Mercury TMDL to determine the need for a limit.
Below find summaries of compliance mercury data from 2017 to 2019. Based on the dataset, the water quality -
based effluent limitation (WQBEL) for mercury is 31.7 ng/l, and the technology -based effluent limit (TBEL)
is 47 ng/l.

Describe proposed permit actions based on mercury evaluation: Mercury evaluation results used Method
1631E. Since no annual average mercury concentration exceeded the WQBEL, and no individual mercury
sample exceeded the TBEL, no mercury limit is required, and no mercury minimization plan (MMP) is required
since the facility is < 2 MGD.
6.7 Other TMDL/Nutrient Management Strategy Considerations
If applicable, describe any other TNDDLs/Nutrient Management Strategies and their implementation within
this permit:
High Rock Lake is presently impaired for several water quality parameters including chlorophyll a, turbidity,
and pH. DWR concluded its modeling efforts with support from a technical advisory committee in 2016. High
Rock Lake is also presently the focus of a plan to revisit North Carolina's nutrient -related water quality
criteria. Nutrient strategy development will commence upon the completion of that effort and in consultation
with stakeholders in the watershed.
1. The NPDES permit had quarterly effluent monitoring for TN and TP, and also has a nutrient reopener
special condition, for the implementation of any nutrient requirements in accordance with any TMDL
or nutrient management strategy for High Rock Lake. The Basin Planning Division reviewed the draft
NPDES permit package in this permit cycle renewal and requested to increase the frequency for
Page 10 of 16

effluent nutrient (TN and TP) monitoring from quarterly to monthly. This plant discharges upstream
of High Rock Lake. There will likely be a need to better understand their load contribution of
nitrogen and phosphorus to the system; therefore, the increase in effluent monitoring frequencies and
the addition of Nutrient Sensitive Waters (NSW) instream monitoring requirements. With this
NPDES permit renewal DWR is adding instream Nitrate and Nitrate (NO2 + NO3), Total Kjeldahl
Nitrogen (TKN), Ammonia (NH3 as N), Total Nitrogen, Total Phosphorous and pH.
6.8 Other WOBEL Considerations
If applicable, describe any other parameters of concern evaluated for WQBELs: NA
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 0 10 7(c) (2) (B), 40CFR 122.47, and EPA May 2007 Memo:
A 3-year schedule of compliance for copper was added to the permit with option for a WER study.
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:
Dutchman WWTP discharges into a Class C waterbody with a water supply watershed located —5.5 miles
downstream. Because 1,4-Dioxane and PFAS have not been evaluated, quarterly monitoring for these
parameters will be added to the permit. In addition, a permit reopener special condition regarding 1,4-Dioxane
based on changes toward limits, monitoring or treatment will be added to the permit.
Since an EPA method for sampling and analyzing PFAS in wastewater is not currently available, the PFAS
sampling requirement in the Permit includes a compliance schedule which delays the effective date of this
requirement until the first full calendar quarter beginning 6 months after EPA has a final wastewater method in
40 CFR 136 published in the Federal Register. This date may be extended upon request and if there are no NC -
certified labs.
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).
If NO, provide a justification for alternative limitations (e.g., waste stabilization pond).
Are 85% removal requirements for BOD5/TSS included in the permit? Y
If NO, provide a justification (e.g., waste stabilization pond). NA
8. Antidegradation Review (New/Expanding Discharge)
The objective of an antidegradation review is to ensure that a new or increased pollutant loading will not
degrade water quality. Permitting actions for new or expanding discharges require an antidegradation review
in accordance with 15A NCAC 213.0201. Each applicant for a new/expanding NPDES permit must document
an effort to consider non -discharge alternatives per 15A NCAC 2H.0105( c)(2). In all cases, existing instream
water uses and the level of water quality necessary to protect the existing use is maintained and protected.
If applicable, describe the results of the antidegradation review, including the Engineering Alternatives
Analysis (EAA) and any water quality modeling results: NA
Page 11 of 16

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 (YESINO): NO
If YES, confirm that antibacksliding provisions are not violated.- NA
10. Monitoring Frequency 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.
The permit proposes monitoring frequencies in compliance with the frequency criteria for class III facilities.
For instream monitoring, refer to Section 4.
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.

14. Fact Sheet Addendum (if applicable)
Were there any changes made since the Draft Permit was public noticed (Yes/No): Yes. The NPDES permit
draft package was reviewed by the Basin Planning Division Nutrient Manager, who provided comments to
protect High Rock Lake
If Yes, list changes and their basis below:
• Increased frequency of nutrient (Total Nitrogen and Total Phosphorous) effluent monitoring from
quarterly to monthly. Better monitoring is needed to develop the nutrient strategy to protect High Rock
Lake.
Page 15 of 16

• Added instream monitoring for turbidity due to turbidity impairment in the watershed.
• Added instream monitoring for Total suspended solids (TSS). This parameter is used when developing
total maximum daily loads (TMDLs).
• Corrected the instream Temperature requirement: from daily to 3/week subject to variable frequency
per State WQ reporting requirements 15A NCAC 2B .0500 and Monitoring Frequency criteria (MF'C)
for class III facilities.
• Added monthly instream monitoring requirements for facilities that impact nutrient sensitive waters
(NSW)/Nutrient sensitive watershed such as: Nitrate and Nitrate (NO2 +NO3), Total Kjeldahl Nitrogen
(TKN), Ammonia (NH3 as N), Total Nitrogen, Total Phosphorous, and pH. This monitoring is needed
to develop the nutrient strategy to protect High Rock Lake. However, as a participant in the Yadkin
Pee -Dee River Basin Association (YPDRBA), instream monitoring is provisionally waived, except for
hardness. Instream monitoring will be immediately reinstated, and the Division shall be notified
immediately should the permittee end its participation in the Association.
• Corrected the effluent table to add monitoring for Zinc. Zinc quarterly monitoring requirement is
maintained per reasonable potential analysis (RPA). Since the predicted Max > 50% of Allowable Cw.

Date: November 30, 2021
Re: Standardized instream monitoring of NSW/nutrient enriched watersheds.
The Basin Planning, Modeling and Assessment, Nonpoint Source and the Classification, Standards and
Rules Review branches in the Planning Section of DWR request standardization of instream (upstream
and downstream) surface water monitoring requirements to be reported as part of the monthly eDMRs
for all major dischargers in NSW watersheds and those identified as nutrient enriched waters across the
state.
Table 1. Minimum set of instream surface water monitoring requirements requested for NPDES permits in all NSW and
nutrient enriched watersheds. Additional parameters, frequency, sample types and locations could be needed based on site
specific monitoring needs. These represent the minimum set of data needed to assess instream impacts from a wastewater
discharger to surface waters of NC.

^ Minimum monitoring frequency. More frequent summer monitoring when conditions are more
variable would be preferred.
Standardized instream surface water monitoring requirements in each NPDES permit would ensure the
availability of a minimum set of data for all streams receiving nutrient laden wastewater effluent. This
information would allow DWR staff (permit writers, basin planners, modelers, etc.) to have a reliable set
of information to evaluate the water quality and the impact of a discharger to the aquatic ecosystem.
This action would ensure instream water quality information is collected equitably by all dischargers.
There are several monitoring coalition programs in place that allow for the collection of instream surface
water data using a collaborative monitoring approach. We continue to support standardized language
for dischargers to forgo their specific instream monitoring requirements by participating in a DWR
approved monitoring coalition. However, over the years monitoring coalitions have come and gone,
have added, and dropped stations which has resulted in changes in available instream data.
Having a minimum set of instream monitoring requirements will eliminate the loss of essential water
quality data if a discharger withdraws from a coalition. An example of this specific situation occurred
when Durham County (Triangle WWTP, NC0026051) pulled out of the Upper Cape Fear River Basin

Association (UCFRBA) in 2012. The coalition dropped one of the monitoring stations resulting in no
instream nutrient monitoring data at that location in a critical nutrient sensitive watershed with an EPA
approved TMDL and a nutrient reduction strategy in place.
The request includes a year-round frequency component for all parameters collected. Year-round data is
necessary to assess water quality models, loading, trends and impact analysis, since standards apply
year-round.
Current coalition monitoring frequencies includes year-round monthly monitoring for nutrients, physical
and bacteriological parameters. They increase the frequency of the physical parameters to twice
monthly in the summer. We request that this be the minimum instream monitoring frequency included
in NPDES permits. More frequent summer monitoring when conditions are more variable would be
preferred as the upstream and downstream stations are specifically used to understand the impacts of a
discharge to surface waters of the state, especial during the most critical periods.
Our efforts to protect and enhance state waters are only possible when we have the data we need to
make a comprehensive assessment. We appreciate your consideration of our requests.

Hi Diana,
Thank you for your patience. My answers to your questions are highlighted in red below. Updates to the
cadmium data for the 2018-2022 reports are still underway, however, I wanted to submit what I have available so
far in the interest of providing you with a timely response.
-Please complete and submit this form to meet the latest application requirements for the updated
application EPA form 2A
enclosed
-If there are additional pollutants with certified methods to be reported, please submit this Chemical
Addendum
none
-If there are additional pollutants without certified methods to be reported, please submit
the Supplemental Chemical Datasheet (attached)
none
-Please let me know if there are any changes in the Facility components or plans for expansion
The facility has undergone several upgrades since this application was initially sent. If there is
any supporting documentation you require, please let me know.
-If the Facility has upstream hardness sampling results, please submit them. If not, please collect 5
samples at the upstream of the discharge over the course of a week. We will need those to calculate
accurate allowable concentrations for the hardness dependent metals
No upstream hardness sampling has been conducted. We will proceed with collecting the 5
samples and will share the results as soon as possible.
Please clarify and update the following entry values in the eDMR as needed:
-Revise the magnitude or units of measurement for the cadmium results reported in the eDMR from
2018-2022.
in progress
Copper, silver, and zinc results reported on 4/3/2018 and 7/3/2018. The magnitude reported
appears to be mg/I, but was reported in ug/I
04-2018 and 07-2018 reports revised
-Revise the priority pollutant analysis (PPA) sampled on 04/28/2021. There were no results for
volatile organics in the package submitted
associated VOC results enclosed
Thank you.
Sincerely,
Madelyn Mills

Good morning, Madelyn
Thank you for submitting the December 20, 2018, NPDES permit renewal application. I look forward
to working with you to complete this NPDES permit renewal. I will appreciate your support with the
following additional/revised information:
-Please complete and submit this form to meet the latest application requirements for the updated
application EPA form 2A
-If there are additional pollutants with certified methods to be reported, please submit this Chemical
Addendum
-If there are additional pollutants without certified methods to be reported, please submit the
Supplemental Chemical Datasheet (attached)
-Please let me know if there are any changes in the Facility components or plans for expansion
-If the Facility has upstream hardness sampling results, please submit them. If not, please collect 5
samples at the upstream of the discharge over the course of a week. We will need those to calculate
accurate allowable concentrations for the hardness dependent metals
Please clarify and update the following entry values in the eDMR as needed:
-Revise the magnitude or units of measurement for the cadmium results reported in the eDMR from
2018-2022. Copper, silver, and zinc results reported on 4/3/2018 and 7/3/2018. The magnitude
reported appears to be mg/I, but was reported in ug/I
-Revise the priority pollutant analysis (PPA) sampled on 04/28/2021. There were no results for
volatile organics in the package submitted
I will set a due date of August 22, 2022. If you need more time, please let me know.
Please let me know if you have any questions along the way.
Thank you,
Diana Yitbarek (she/her)

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.

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.
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 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
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. NCO021491
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 - I
Ctow I + { [KPO] [SS(l+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 (le. 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) 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 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. NC0021491
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
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 August 1, 2022, Alex Lowe of the DWR Winston-Salem Regional Office conducted a routine
pretreatment compliance inspection of the Town of Mocksville's pretreatment program, as run by
Envirolink, Inc. Piedmont -Metro Area Manager Josh Powers was present throughout the inspection to
assist Mr. Lowe.
Mocksville's pretreatment program elements were all up to date and available for review. The
headworks analiysis submitted to the State in January 2022 is still under review. The next assigned
update for any pretreatment program element is the industrial waste survey, which is due on June 30,
2024.
This program consists of only one SIU, Brakebush Bros. Inc, which is a chicken cooking and
packaging facility. A review of the SIU files indicates that Brakebush has had some compliance
concerns in the past 12 months, with repeated violations of both flow and BOD. Monthly monitoring
reports are submitted by the SIU to Envirolink in an effort to ensure compliance, and all of these
records were available for review upon inspection. The most recent six month period showed three
violations, two in March and one in April 2022. A Notice of Violation was assigned for each of these
exceedences.
Records for this program were properly maintained and well organized. No instances of permit
non-compliance were uncovered during this inspection. This program is considered satisfactory.
