Briefly describe the proposed permitting action and facility background: The Town of Jefferson has
applied for NPDES permit renewal and submitted a renewal application dated May 16, 2022. Review of
the application found it incomplete with effluent pollutant scans (PPAs), second species test reports, and
chemical addendum lacking. The PPAs and Chemical Addendum were received upon request on 1/12/2023
along with a set of 2nd species toxicity tests using the same species as the regular tests; PPAs were sampled
on 7/20/2020, 5/13/2021 and 11/16/2022. Upon request 2ad species tests were conducted in March, April,
May and June 2023.
At the time of application submission, the facility served a population of —1400 residents including the
town of Jefferson. The Town has an active pretreatment program, with one SIU, American Emergency
Vehicles, a metal finisher under 40 CFR 433.17. Since that time, the SIU had changed ownership and has
become an assembly plant, no longer under 40 CFR 433.17.
Sludge management. The facility produces two types of sludge: Class B Liquid Sludge, which is land -
applied on the facility property under WQ0004166; and Class A Dry Sludge, which is land -applied onto
hayfields under WQ0022155.

4. Instream Data Summary
Instream monitoring may be required in certain situations, for example: 1) to verify model predictions when
model results for instream DO are within 1 mg/1 of instream standard at full permitted flow; 2) to verify
model predictions for outfall diffuser; 3) to provide data for future TMDL; 4) based on other instream
concerns. Instream monitoring may be conducted by the Permittee, and there are also Monitoring Coalitions
established in several basins that conduct instream sampling for the Permittee (in which case instream
monitoring is waived in the permit as long as coalition membership is maintained).
Is this facility a member of a Monitoring Coalition with waived instream monitoring (YIN): No.
Name of Monitoring Coalition: N/A.
If applicable, summarize any instream data and what instream monitoring will be proposed for this permit
action: The current permit requires instream monitoring for Hardness, Temperature and Dissolved Oxygen
(DO). The upstream location is just below the NC Highway 16 bridge (100 feet above discharge), and the
downstream is just beyond the end of the aerobic digester (100 yards downstream of discharge). No water
supply watershed lies downstream of the outfall between point of discharge and the Virginia state line,
—30.5 miles from the discharge. Hardness is sampled upstream for calculation of dissolved to total metals
for hardness -dependent metals, including Copper, and is addressed in the Reasonable Potential Analysis
(RPA) portion of Section 6 - Water Quality -Based Effluent Limits (WQBEL).
Instream data were collected by the Permittee at the above locations. Data were obtained from the
Permittee-submitted DMRs spanning December 2018 through May 2023 for review. Data were compared
against corresponding instream water quality standards and between stations as well as concurrent effluent
data for assessment of effluent impacts. Averages were compared using Student's t-tests with levels of
significant differences set atp = 0.05. Summary data are in Table 2.

Dissolved Oxygen (DO) — Instream DO remains in the permit as a parameter of concern for aquatic life.
Reviewed instream DMR data revealed summer lows to be above the stream standard of 6.0 mg/L for ORW
that lies —0.5 miles downstream of the discharge. No statistically significant differences were detected
between the two station DO averages. Concurrent effluent DO data were similar on average with no values
below 6 mg/L.
Page 4 of 13

NCO021709
Temperature - Instream Temperature remains in the permit as a parameter of concern for aquatic life.
Temperatures in both sites were below the standard of 29 °C for upper piedmont and mountain waters. No
statistically significant differences were detected between the two station temperature averages. There was
no occurrences where the downstream temperature exceeded the water quality standard of 2.8 °C above the
natural water temperature when compared to upstream data. Concurrent effluent temperatures were higher
on average with winter lows substantially higher than instream averages.
Conductivity and Fecal Coliform are two instream parameters that are not in the current permit. The facility
has a pretreatment program, which would necessitate the inclusion of instream monitoring for Conductivity
per 2002 Division guidance (per Instream Conductivity & Fecal Coliform Monitoring memo, 4/22/2002).
However, the industrial user is an assembly plant, which is not expected to have high conductivity values
in its waste stream. Specific Conductance is monitored at Ambient Monitoring Station K4500000, located
—16 miles downstream. Data from this station show a decrease in conductance from —90 µS/cm in 2015 to
—50 µS/cm in 2020. Based on these considerations, Conductivity / Specific Conductance was not be added
to the permit.
Fecal Coliform is not required since the receiving stream is not listed as impaired for this parameter, nor is
it a Class B waterbody. Instream monthly data from Ambient Monitoring Station K4500000 have a
geometric mean of 49 cfu/100 mL from 2015-2020, with 14 occurrences < 200 cfu/100 mL. Based on this
finding, more information is needed to determine if the water quality standard of 200 cfu/ 100 mL geomean
of at least 5 samples collected within a 30-day period (15A NCAC 02B .0211), Fecal Coliform instream
monitoring was added to the permit.
5. Compliance Summary
Summarize the compliance record with permit effluent limits (past 5 years): From November 2017 through
October 2022 the facility had reported exceedences in BOD and Total Copper (see Table 3).

Summarize the compliance record with aquatic toxicity test limits and any second species test results (past
5 years): The facility passed all 20 quarterly chronic toxicity tests, as well as all 4 second species chronic
toxicity tests. Second species tests were sampled on March, April, May and June 2023.
Summarize the results from the most recent compliance inspection: The most recent facility inspection, a
pretreatment inspection conducted on 12/6/2021, reported the facility's pretreatment program to be out of
compliance by allowing its Industrial User Permit (IUP) for the sole SIU to expire under the impression
that the SIU was shutting down to relocate under a different name. A Notice of Violation was issued for the
reported violation. The IUP was since renewed, effective 2/l/2022, addressing the violation.
The most recent compliance inspection was conducted on 2/23/2023 and discovered that the tertiary filter
treatment was shut down and bypassed to disinfection without Division notification. The inspection report
signified the observation as a violation to which a NOD was issued.

6. Water Quality -Based Effluent Limitations (WQBELs)
Dilution and Mixin Zones
ones
In accordance with 15A NCAC 213.0206, the following streamflows are used for dilution considerations
for development of WQBELs: 1 Q 10 streamflow (acute Aquatic Life); 7Q 10 streamflow (chronic Aquatic
Life; non -carcinogen HH); 30Q2 streamflow (aesthetics); annual average flow (carcinogen, HH).
If applicable, describe any other dilution factors considered (e.g., based on CORMIX model results): NA
If applicable, describe any mixing zones established in accordance with 15A NCAC 2B.0204(b): NA
Oxygen -Consuming Waste Limitations
Limitations for oxygen -consuming waste (e.g., BOD) are generally based on water quality modeling to
ensure protection of the instream dissolved oxygen (DO) water quality standard. Secondary TBEL limits
(e.g., BOD = 30 mg/L for Municipals) may be appropriate if deemed more stringent based on dilution and
model results.
If permit limits are more stringent than TBELs, describe how limits were developed: Because the facility
lies —0.5 miles upstream of the South Fork / New River ORW, rule 15A NCAC 02B .0225 Outstanding
Resource Waters applies. Section (e)(4)(C)(i) of the rule requires effluent limitations for BOD5 to be 5
mg/L and NH3-N to be 2 mg/L of new or expanded NPDES permitted wastewater discharges located
upstream of the South Fork New and New Rivers ORW Area to protect the ORW. The Jefferson WWTP
had expanded from 0.30 MGD to 0.60 MGD in 2006, after the rule effective date of 1995 and amended
effective dates of 1996-2004. No changes were made to permit limits for BOD5 and NH3-N.
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/L (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 µg/L) and capped at 28 µg/L (acute impacts). Due to analytical issues, all TRC values
reported below 50 µg/L are considered compliant with their permit limit.
Describe any proposed changes to ammonia and/or TRC limits for this permit renewal: The current permit
limits for both TRC and NH3-N are based on a wasteload allocation (WLA) analyses. The WLA was
performed again for both parameters, yielding results that are not different than the previous WLA results.
See Oxygen -Consuming Waste Limitations above for more information regarding ammonia limits. 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 '/2 detection limit for "less than" values; and 4) streamflows used for dilution
consideration based on 15A NCAC 213.0206. Effective April 6, 2016, NC began implementation of
Page 6 of 13

NC0021709
dissolved metals criteria in the RPA process in accordance with guidance titled NPDES Implementation of
Instream Dissolved Metals Standards, dated June 10, 2016.
Effluent and instream (upstream) Hardness monitoring is required in the current permit. Permittee-
submitted DMR Hardness data were used in the RPA for hardness -dependent metals.
A reasonable potential analysis was conducted on effluent toxicant data collected between December 2018
through May 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:
o Total Copper — MA = 17.7 µg/L, DM = 21.8 µg/L
o Total Cyanide — MA = 8.4 µg/L, DM = 32.8 µg/L
o Total Zinc MA = 252 µg/L, DM = 252 µg/L
• Monitoring Only. The following parameters will receive a monitor -only requirement since they
did not demonstrate reasonable potential to exceed applicable water quality standards/criteria, but
the maximum predicted concentration was > 50% of the allowable concentration:
• 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,
Beryllium, Cadmium, Chromium, Total Phenolic Compounds, Lead, Nickel, Silver, and Selenium.
o Silver — no monitoring is added despite all reported data were nondetects above the PQL
of 1 µg/L and allowable concentrations are 0.10 µg/L chronic and 0.80 µg/L acute as the
data are from three pollutant scans. The correct PQL will be added to Silver in the
parameter table in the Effluent Pollutant Scan condition.
• POTW Effluent Pollutant Scan Review: Three effluent pollutant scans were evaluated for
additional pollutants of concern. Samples for the pollutant scans were collected on 7/22/2020,
5/13/2021, and 11/16/2022. Only Chloroform was detected.
o The following parameter(s) will receive a water quality -based effluent limit (WQBEL)
with monitoring, since as part of a limited data set, two samples exceeded the allowable
discharge concentration: None.
o The following parameter(s) will receive a monitor -only requirement, since as part of a
limited data set, one sample exceeded the allowable discharge concentration: None.
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.
Toxici . 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 30%
effluent will continue on a quarterly frequency.

NC0021709
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/L) 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/L) and/or if any individual value exceeds a TBEL value of 47 ng/L.
Describe proposed permit actions based on mercury evaluation: The current permit requires mercury to
be monitored via the three effluent pollutant scans. Their results are below:

Because no result was higher than either the TBEL or WQBEL, no limits are required. Because the facility
is < 2 MGD, no MMP is required. No changes were made to the permit; mercury monitoring will continue
via the three effluent pollutant scans.
Other TMDL/Nutrient Management Strategy Considerations
If applicable, describe any other TMDLs/Nutrient Management Strategies and their implementation within
this permit: The New River Basin has neither any TMDLs nor a Nutrient Management Strategy. However,
long-term trends at instream station K4500000, —16.5 miles downstream of the discharge, show a steady
increase in Total Nitrogen concentrations, in particular NO3-N + NOz-N, but not Total Phosphorus. Effluent
Total Nitrogen and Total Phosphorus are currently monitored semi-annually per facility size (< 1 MGD)
and river sub -basin (New) as specified in 15A NCAC 02B .0508. Based on these trends, effluent monitoring
for nutrients (nitrogen and phosphorus) will be increased to quarterly, and the Total Nitrogen components
Total Kjeldahl Nitrogen (TKN) and Nitrate -Nitrite Nitrogen (NO3-N + NOz-N) was added. To track the
effluent's impact on instream nutrients, quarterly monitoring for the nutrient parameters above was also
added, at a quarterly frequency both up- and downstream of the effluent. Considering the distance of the
downstream station from the outfall, an option was added to the requirement allowing the Permittee to
request reassessment of nutrient monitoring after 24 months for a reduction in monitoring frequency to
semi-annually.
Other WQBEL Considerations - Permit Limit Development
If applicable, describe any other parameters of concern evaluated for WQBELs: Emerging contaminants
PFAS and 1,4-Dioxane were considered when the facility submitted its Chemical Addendum on 1/12/2023.
The Town responded: "The Town of Jefferson has one permitted Significant Industrial User. We have no
Page 8 of 13

NC0021709
records to indicate their use of 1,4-Dioxane or PFAS chemicals, nor is there reason to believe any of these
compounds exist in significant volumes at any contributor to the flow of the Jefferson sanitary sewer
collection system. " The receiving stream does not enter any water supply waters before crossing the
Virginia state line —30.5 miles downstream of the discharge. The facility's permitted SIU is an assembly
plant that is not a potential 1,4-Dioxane source; no requirements for 1,4-Dioxane were added to the permit.
However, based on the pervasive nature of these chemicals and following EPA guidance on PFAS
monitoring (memo, 12/5/2022), quarterly monitoring for PFAS will be added to the permit to generate data
for future evaluation.
If applicable, describe any compliance schedules proposed for this permit renewal in accordance with 15A
NCAC 2K 0107(c)(2)(B), 40CFR 122.47, and EPA May 2007 Memo: NA.
If applicable, describe any water quality standards variances proposed in accordance with NCGS 143-
215.3(e) and 15A NCAC 2B.0226 for this permit renewal: NA
7. Technology -Based Effluent Limitations (TBELs)
Municipals (if not applicable, delete and skip to Industrials)
Are concentration limits in the permit at least as stringent as secondary treatment requirements (30 mg1L
BOD51TSS for Monthly Average, and 45 mg/L for BOD51TSS 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. Reviewed data found 3
monthly occurrences below 85% BOD removal and 3 occurrences below 85% TSS removal from December
2018 — May 2023.
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
Page 9 of 13

NC0021709
may be relaxed (e.g., based on new information, increases in production may warrant less stringent TBEL
limits, or WQBELs may be less stringent based on updated RPA or dilution).
Are any effluent limitations less stringent than previous permit (YES/NO): NO.
If YES, confirm that antibacksliding provisions are not violated: NA.
10. Monitoring Requirements
Monitoring frequencies for NPDES permitting are established in accordance with the following regulations
and guidance: 1) State Regulation for Surface Water Monitoring, 15A NCAC 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.
No effluent parameters are sampled at reduced monitoring frequencies. The Permittee requested that the
target parameters BOD, TSS, Ammonia and Fecal Coliform be reduced in their monitoring frequencies
according to the Division's DWQ Guidance on the Reduction of Monitoring Frequencies in NPDESPermits
for Exceptionally Performing Facilities (DWQ 2012). Effluent data were evaluated for reduced monitoring
frequencies and found to meet the criteria for the following target parameters: TSS and Ammonia but not
Fecal Coliform. BOD did not meet the approval criteria of two or less non -monthly violations within the
previous year; three weekly average exceedances were reported since May 2022. Monitoring frequencies
was reduced to 2/week for TSS and Ammonia; 3/week monitoring is maintained for BOD and Fecal
Coliform.
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. Effective December 21, 2020, NPDES regulated facilities will be required to submit
additional NPDES reports electronically. This permit contains the requirements for electronic reporting,
consistent with Federal requirements.

Analysis - 28 Aug 2018
This site on Naked Creek in Ashe County lies just upstream of the Town of Jefferson WWTP and the Jefferson Landing golf course but downstream
of the Town of Jefferson. This segment on Naked Creek has been sampled for benthic macro!nvertebrates since 1986 when it initially received a
Good -Fair rating.
Sampling in 2018 resulted in a Good -Fair rating for the third consecutive time. EPT taxa richness was higher than in 2013 but significantly lower than in
2008. It was noted during previous sampling events that some event occurred between 2008 and 2013 to affect water quality particular as it pertains
to benthic faunal richness (see analysis of site KB139 for 2013). It was also previously noted that Naked Creek has been substantially altered with
much of its riparian vegetation removed along the length of the stream. However, the combined urban and agricultural nature of this stream likely
prevents the stream from rating higher than the current bioclassification. While the bioclassification is the same as the benthic site on Naked Creek
below the golf course (Site K13139), higher EPT richness and abundance indicates that the golf course is likely having a deleterious effect on the
monitoring site downstream.

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
On February 23rd, 2023, Tricia Lowery met with Tim Church (ORC) to perform Compliance Evaluation
Inspection at Jefferson WWTP (NPDES PERMIT#NC0021709). This inspection consisted of two
parts: 1) in -office file review, and 2) on -site inspection of the treatment facility. Tim Church assisted
with the in -office review, and escorted inspector through the facility during the on -site inspection.
The attached EPA inspection form detail the areas that were evaluated with their respective
comments.
Area found to be of concern are:
1. The 2 traveling bridge teritary filters are out of service. Currently facility is bypassing this
treatment and sending effluent from secondary clarifiers to chlorine contact chamber. NPDES Permit
Part II, Section C(4)(c)(1)(B) states bypass from the treatment facility is prohibited and enforcement
action can be taken against a Permittee unless there were no feasible alternatives to the bypass.
2. DWR was not notified of bypass at the time it occured. NPDES Permit Part II, Section C(4)(b)(2)
states: The Permittee shall submit notice of an unanticipated bypass as required in Part II.E.6.
(24-hour notice).

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
On Monday, December 6, 2021, Alex Lowe of the Winston-Salem Regional Office conducted a
routine Pretreatment Compliance Inspection at the Town of Jefferson WWTP. Water Resources
Director Tim Church was present for the inspection.
Lowe reviewed the pretreatment program elements and found that all were up to date and properly
documented with letters from the DWR. See table (item number 28 on PCI Report) for dates of latest
element approvals and dates of required renewal.
A file review of the only SIU in the program, American Emergency Vehicles, was conducted. This SIU
is a categorical industrial user under 40 CFR 433.17. Mr. Church had informed Mr. Lowe ahead of
the meeting that the permit for this SIU had expired in July of 2021, but had not been renewed
because the company was vacating it's current address and moving to a new location under a new
name, Remount Emergency Vehicles (see full narrative as document NC0021709_AEV
Narrative_2021-11-18 on Laserfiche or attached to this inspection report). Lowe confirmed with Mr.
Church that the permit had expired and that the facility was continuing to operate at a reduced
capacity with no permit. Mr. Lowe told Mr. Church that this likely constituted a violation of the POTW's
permit, and later confirmed that allowing the permit to lapse while the SIU continued to operate
constitutes failure to maintain legal authority under permit Part IV, Section D, subsection five (per
CFR 403.3 (v) and 15A NCAC 02H .0906 (b)(6)). An NOV has thus been issued in conjunction with
this inspection report.
Mr. Church was helpful and forthright in accessing and sharing this information with Mr. Lowe, and
stated that he is working on permitting Remount Emergency Vehicles immediately.
This program is found to be non -compliant, and requires follow-up to ensure that both AEV and REV
are permitted as soon as possible as both are qualified under 40 CFR 433.17.

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/WQBELs for Hardness -Dependent Metals - Freshwater
The RPA is designed to predict the maximum likely effluent concentrations for each metal of concern,
based on recent effluent data, and calculate the allowable effluent concentrations, based on applicable
standards and the critical low -flow values for the receiving stream.
If the maximum predicted value is greater than the maximum allowed value (chronic or acute), the
discharge has reasonable potential to exceed the standard, which warrants a permit limit in most cases. If
monitoring for a particular pollutant indicates that the pollutant is not present (i.e. consistently below
detection level), then the Division may remove the monitoring requirement in the reissued permit.
To perform a RPA on the Freshwater hardness -dependent metals the Permit Writer compiles the
following information:
• Critical low flow of the receiving stream, 7Q 10 (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.
Page 2 of 4

Permit No. NCO021709
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) + (s7Q 10, 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 1 + { [Kpo] [ss(I+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:
1 Q 10 = used in the equation to protect aquatic life from acute toxicity
Page 3 of 4

Permit No. NC0021709
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.
