Subject: Draft NPDES Permit Renewal
Permit NC0024236
Kinston Regional WRF
Lenoir County
Grade IV Biological WPCS
SIC Code 4952
Dear Mr. Sears:
Enclosed with this letter is a copy of the Draft NPDES permit renewal for your facility. Please
review this draft carefully to ensure thorough understanding of the requirements and conditions it
contains. There are several changes from the existing permit, including the following:
• Based on the reasonable potential analysis(RPA) showing no reasonable potential for zinc
or copper to violate water quality standards, quarterly monitoring of zinc and copper have
been removed from the permit.
• Based on the mercury evaluation showing only one mercury data point was greater than 1
ng/L,the mercury minimization plan(MMP)has been removed from this permit.
• The City of Kinston reported Total Silver at less than detection, with detection levels< 5
.tg/L in the three Effluent Pollutant Scans and in the Discharge Monitoring Reports. The
City's permit discharge requirement is 0.984 µg/L for Total Silver. DWR's laboratory
identifies the Practical Quantification Limit(PQL) for Total Silver as approximately 1
µg/L. The City should test for Total Silver down to the recommended PQL and as long as
the City reports effluent Total Silver less than the PQL or the lower reporting level of the
procedure,the City will be considered in compliance with its permit discharge
requirement(limit). Therefore, in accordance with 15A NCAC 2B .0500, all data
generated for Total Silver shall be reported to the lower reporting level of the procedure.
The Division can modify this permit and add a limit or add limits during the next renewal
if this regulation is not satisfied.
• Some of the wording has changed in Special Condition A. (5.), Chronic Toxicity Permit
Limit, please review each paragraph carefully.

• Special Condition A. (6.) has(been modified to include the specific threeyears in which
p
the Effluent Pollutant Scan shall be performed (2020, 2021, 2022). In addition, at the end
of the Special Condition, 2nd species Toxicity Testing Requirements for municipal permit
renewals per Federal Regulations [40 CFR 122.21(j)(5)] have been added.
• Federal regulations require electronic submittal of all discharge monitoring reports
(DMRs) and program reports. The requirement to continue reporting discharge monitoring
data electronically using the NC DWR's Electronic Discharge Monitoring Report(eDMR)
internet application has been added to your NPDES permit[See Special Condition A. (7.)].
• Parameter characteristic codes have been added to the Effluent Limitations and Monitoring
Requirements [ See A. (1.)].
• Regulatory citations have been added to the permit.
The NPDES Standard Conditions (Parts II, III, and IV) are not included with this draft. They can

a. The Permittee shall calculate monthly and annual TN Loads as follows:
i. Monthly TN Load (lb/mo)=TN x TMF x 8.34
where:
TN = the average Total Nitrogen concentration(mg/L)of the composite
samples collected during the month
TMF = the Total Monthly Flow of wastewater discharged during the
month(MG/mo)
8.34 = conversion factor, from(mg/L x MG) to pounds
ii. Annual TN Load (lb/yr) = Sum of the 12 Monthly TN Loads for the calendar year
b. The Permittee shall report monthly Total Nitrogen results (mg/L and lb/mo) in the discharge
monitoring report for that month and shall report each year's annual results (lb/yr) in the
December report for that year.
A. (3)ANNUAL LIMITS FOR TOTAL NITROGEN
[G.S. 143-215.1(b)]
a. Total Nitrogen(TN)allocations and TN Load limits for NPDES dischargers in the Neuse River
basin are annual limits and are applied for the calendar year.

in this Permit if:
i. the Permittee's annual TN Load is less than or equal to said limit, or
ii. the Permittee is a Co-Permittee Member of a compliance association.
c. If the Permittee is not a co-permittee member of a compliance association and the Permittee's
cumulative annual TN discharge exceeds the effective TN Load limit in this permit at any point
during the calendar year, the Permittee is in violation of its TN Load limit, and each day of a
continuing violation shall constitute a separate violation.
d. The TN Load limit in this Permit(if any)may be modified as the result of allowable changes in
the Permittee's TN allocation.
i. Allowable changes include those resulting from purchase of TN allocation from the
Wetlands Restoration Fund;purchase, sale, trade, or lease of allocation between the
Permittee and other dischargers; regionalization; and other transactions approved by the
Division.
ii. The Permittee may request a modification of the TN Load limit in this Permit to reflect

A. (5) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
[15A NCAC 02B.0200]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 6.1%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined
in the"North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure,"Revised December
2010, or subsequent versions or"North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (Revised- December 2010) or subsequent versions. The tests will be performed during
the months of January,April, July and October. These months signify the first month of each
three-month toxicity testing quarter assigned to the facility. Effluent sampling for this testing must
be obtained during representative effluent discharge and shall be performed at the NPDES permitted
final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or
ChV below the permit limit, then multiple-concentration testing shall be performed at a
minimum, in each of the two following months as described in "North Carolina Phase II
Chronic Whole Effluent Toxicity Test Procedure" (Revised-December 2010) or subsequent
versions.

Additional Toxicity Testing Requirements for Municipal Permit Renewal. Please note that Municipal
facilities that are subject to the Effluent Pollutant Scan requirements listed above are also subject to additional
toxicity testing requirements specified in Federal Regulation 40 CFR 122.21(j)(5). The US EPA requires four(4)
toxicity tests for a test organism other than the test species currently required in this permit. The multiple
species tests should be conducted either quarterly for a 12-month period prior to submittal of the permit renewal
application,or four tests performed at least annually in the four and one half year period prior to the application.
These tests shall be performed for acute or chronic toxicity,whichever is specified in this permit. The multiple
species toxicity test results shall be filed with the Aquatic Toxicology Branch at the following address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh,North Carolina 27699-1621
Contact the Division's Aquatic Toxicology Branch at 919-743-8401 for guidance on conducting the additional
toxicity tests and reporting requirements. Results should also be summarized in Part E(Toxicity Testing Data)
of EPA Municipal Application Form 2A, when submitting the permit renewal application to the NPDES
Permitting Unit.
A. (7) ELECTRONIC REPORTING OF MONITORING REPORTS
[G.S. 143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and
program reports. The final NPDES Electronic Reporting Rule was adopted and became effective on
December 21, 2015.
NOTE: This special condition supplements or supersedes the following sections within Part II of
this permit(Standard Conditions for NPDES Permits):
• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
1. Reporting Requirements (Supersedes Section D. (2.) and Section E. (5.) (a)1
The permittee shall report discharge monitoring data electronically using the NC DWR's
Electronic Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month
and submitted electronically using eDMR. The eDMR system allows permitted facilities to
enter monitoring data and submit DMRs electronically using the internet. Until such time that
the state's eDMR application is compliant with EPA's Cross-Media Electronic Reporting
Regulation(CROMERR),permittees will be required to submit all discharge monitoring data to
the state electronically using eDMR and will be required to complete the eDMR submission by
printing, signing, and submitting on signed original and a copy of the computer printed eDMR
to the following address:
NC DEQ/Division of Water Reso ces/Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh,North Carolina 27699-1617
• Page 10 of 12
Permit NC0024236
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the
facility being physically located in an area where less than 10 percent of the households have
broadband access,then a temporary waiver from the NPDES electronic reporting requirements
may be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1,
1.1, 2, 3) or alternative forms approved by the Director. Duplicate signed copies shall be
submitted to the mailing address above. See"How to Request a Waiver from Electronic
Reporting" section below.
Regardless of the submission method, the first DMR is due on the last day of the month
following the issuance of the permit or in the case of a new facility, on the last day of the month
following the commencement of discharge.
Starting on December 21,2020, the permittee must electronically report the following
compliance monitoring data and reports, when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports; and
• Clean Water Act(CWA) Section 316(b) Annual Reports.
The permittee may seek an electronic reporting waiver from the Division(see "How to Request
a Waiver from Electronic Reporting" section below).
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the
time of each electronic submission. The permittee should use the EPA's website resources to
identify the initial recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the
entity(EPA or the state authorized by EPA to implement the NPDES program) that is the

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
Page 3 of 11
Monitoring Coalitions established in several basins that conduct instream sampling for the Permittee(in
which case instream monitoring is waived in the permit as long as coalition membership is maintained).
If applicable, summarize any instream data and what instream monitoring will be proposed for this
permit action: Data pertaining to temperature,conductivity,dissolved oxygen and fecal coliform were
analyzed from Monitoring Location J6150000, located upstream of the facility, and Monitoring Location
J6250000, located downstream of the facility.During this analysis,which utilized data ranging from
January 2014 to December 2017, it was concluded that the downstream DO ranged from 11.8 to 5.9
mg/L,with an average of 7.59 mg/L.The average DO is above the 6mg/L dissolved oxygen minimum
WQBEL utilized in this and previous Kinston Regional WRF permits.Based on a p-value of< .05,it was
concluded with 95%confidence that no significant difference between upstream and downstream DO
exists.
Downstream temperature ranged from 29.9 to 5.7 degrees Celsius, with an average of 20.5 degrees
Celsius.The temperature rise(downstream temperature minus upstream temperature)ranged from 0.3
degrees Celsius to 1.3 degrees Celsius.This is below the 2.8 degrees Celsius temperature rise maximum.
It was concluded with 95%confidence,based on a p-value of< .05,that there is no statistically
significant difference between upstream and downstream temperature.
The geometric mean limit for fecal coliform is 200/100mL. Additionally, fecal coliform samples cannot
exceed 400/100mL in more than 20%of samples taken.The geometric mean of downstream fecal
coliform data was 90.4/100mL and exceedances of 400/100mL accounted for 10.4%of samples. It was
also concluded with 95%confidence and a p-value of<.05 that activity at the treatment facility was
found to have negligible effect on instream conductivity.
Is this facility a member of a Monitoring Coalition with waived instream monitoring(Y/N): Y
Name of Monitoring Coalition: Lower Neuse Basin Association
5. Compliance Summary
Summarize the compliance record with permit effluent limits(past 5 years):The facility reported no limit
violations from 2014 to present.
Summarize the compliance record with aquatic toxicity test limits and any second species test results
(past 5 years): The facility passed 18 of 18 quarterly chronic toxicity tests,as well as 4 of 4 second
species chronic toxicity tests.
Summarize the results from the most recent compliance inspection: The last facility inspection conducted
in July of 2017 reported that the facility was well maintained and operated.
6. Water Quality-Based Effluent Limitations (WQBELs)
Dilution and Mixing Zones
In accordance with 15A NCAC 2B.0206,the following streamflows are used for dilution considerations
for development of WQBELs: 1Q10 stre flow(acute Aquatic Life); 7Q10 streamflow(chronic Aquatic
Life; non-carcinogen HH); 30Q2 stream ow(aesthetics); annual average flow(carcinogen,HH).
If applicable, describe any other dilution factors considered(e.g., based on CORMIX model results):NA
Page 4 of 11
with 15A2B.
If applicable, describe any mixing zones established in accordance wtt NCAC 0204(b): NA
Oxygen-Consuming Waste Limitations
Limitations for oxygen-consuming waste(e.g.,BOD)are generally based on water quality modeling to
ensure protection of the instream dissolved oxygen(DO)water quality standard. Secondary TBEL limits
(e.g.,BOD=30 mg/1 for Municipals)may be appropriate if deemed more stringent based on dilution and
model results.
If permit limits are more stringent than TBELs, describe how limits were developed: Limitations for
BOD are water quality-based,BAT limits for new and expanded dischargers in the Neuse River Basin.
and are the same as in the previous permit. 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.
Limitations for Total Residual Chlorine(TRC)are based on the NC water quality standard for protection
of aquatic life(17 ug/1)and capped at 28 ug/1(acute impacts). Due to analytical issues,all TRC values
reported below 50 ug/1 are considered compliant with their permit limit.
Describe any proposed changes to ammonia and/or TRC limits for this permit renewal: Wasteload
Allocation(WLA)calculations resulted in a cap of 28 ug/L TRC,which is the same as the current permit.
Therefore,there are no proposed changes for TRC.The limits for ammonia were set based on water
quality-based,BAT limits for new and expanded dischargers in the Neuse River Basin.There are no
changes for ammonia.
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 Leve1/95%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 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 2014
and April 2018. 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:
Page 5 of 11
r r
• 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: N/A
• 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
o Permittee must monitor to lowest PQL(< 1 ug/L)
• 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, Chlorides,Chromium, Cyanide,Lead,Mercury,
Molybdenum,Nickel, Selenium,Zinc
• POTW Effluent Pollutant Scan Review:Three effluent pollutant scans 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:N/A
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:N/A
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
Phenolic Compounds,Fluoride
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 requirem nt: The permit requires quarterly chronic toxicity testing at
6.1%effluent concentration.
Mercury Statewide TMDL Evaluation
There is a statewide TMDL for mercuryproved 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 7 kg/year(81 lb/year),and is applicable to municipals and
industrial facilities with known mercury 'scharges. Given the small contribution of mercury from point
sources(^2%of total load),the TMDL emphasizes mercury minimization plans(MMPs)for point source
Page 6 of 11
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.
Table 2. Mercury Effluent Data Summary
2015 2016 2017 2018
#of Samples 3 4 4 1
Annual Average Conc.ng/L 0.9 0.5 0.5 0.5
Maximum Conc.,ng/L 1.66 0.5 0.5 0.5
TBEL,ng/L 47
WQBEL,ng/L 196.9
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. A mercury minimization plan(MMP)was implemented in the previous permit. Since
the facility reported only one quantifiable level of mercury(> 1 ng/1),the mercury minimization plan
(MMP)will be removed from this permit.
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
rules in December 1997,classifying the entire Neuse River Basin as Nutrient Sensitive Waters.The point
source rule(T15A NCAC 2B .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.
Page 7 of 11
Nitrogen:The permit includes nutrient limits consistent with the Nutrient Management Strategy rule(T15A
NCAC 2B .0234).Under the new rule,the Permittee receives a TN Load limit of 126,711 lb/yr,a calendar
year limit. The limit reflects the Permittee's original allocation plus additional allocation received upon
regionalization of Peachtree WWTP's discharge.
Table 3: Annual Reported TN Load(Allocation= 126,711 lb/yr)
2014 2015 2016 2017
32,043 lb/yr 37,720 lb/yr 46,644 lb/yr 28,528 lb/yr
25.3%of 29.8%of 36.8%of 22.5%of
allocation allocation allocation allocation
Note: Reported flow approximately 29%of its 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,issued December 30,2002.
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 2014 through 2017 quarterly average
reported TP ranged from 0.13 to 1.26 mg/L.
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/1
BODS/TSS for Monthly Average, and 45 mg/1 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 BODS/TSS included in the permit? YES
If NO,provide a justification (e.g., waste stabilization pond). NA
8. Anti degradation 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 a tidegradation review, including the Engineering Alternatives
Analysis(EAA)and any water quality mo eling results:NA
9. Antibacksliding Review:
Sections 402(o)(2)and 303(d)(4)of the A and federal regulations at 40 CFR 122.44(1)prohibit
backsliding of effluent limitations in NP ES permits.These provisions require effluent limitations in a
Page 8 of 11
reissued permit to be as stringent as those in thepreviouspermit,with some exceptions where limitations
g eP
may be relaxed(e.g.,based on new information,increases in production may warrant less stringent TBEL
limits,or WQBELs may be less stringent based on updated RPA or dilution).
Are any effluent limitations less stringent than previous permit(YES/NO): NO
If YES, confirm that antibacksliding provisions are not violated: NA
10. Monitoring Requirements
Monitoring frequencies for NPDES permitting are established in accordance with the following
regulations and guidance: 1) State Regulation for Surface Water Monitoring, 15A NCAC 2B.0500;2)
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.
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.

General Information on the Reasonable Potential Analysis (RPM
The RPA process itself did not change as the result of the new metals standards.However, application of
the dissolved and hardness-dependent standards requires additional consideration in order to establish the
numeric standard for each metal of concern of each individual discharge.
The hardness-based standards require some knowledge of the effluent and instream(upstream)hardness
and so must be calculated case-by-case for each discharge.
Metals limits must be expressed as `total recoverable'metals in accordance with 40 CFR 122.45(c).The
discharge-specific standards must be converted to the equivalent total values for use in the RPA
calculations.We will generally rely on default translator values developed for each metal(more on that
below),but it is also possible to consider case-specific translators developed in accordance with
established methodology.
RPA Permitting Guidance/WQBELs for Hardness-Dependent Metals - Freshwater
The RPA is designed to predict the maximum likely effluent concentrations for each metal of concern,
based on recent effluent data,and calculate the allowable effluent concentrations,based on applicable
standards and the critical low-flow values for the receiving stream.
If the maximum predicted value is greater than the maximum allowed value(chronic or acute),the
discharge has reasonable potential to exceed the standard,which warrants a permit limit in most cases. If
monitoring for a particular pollutant indicates that the pollutant is not present(i.e.consistently below
detection level),then the Division may remove the monitoring requirement in the reissued permit.
1. To perform a RPA on the Freshwater hardness-dependent metals the Permit Writer compiles the
following information:
• Critical low flow of the receiving stream, 7Q10(the spreadsheet automatically calculates
the 1Q10 using the formula 1Q10=0.843 (s7Q 10, cfs)0.993
• Effluent hardness and up tream hardness, site-specific data is preferred
• Permitted flow
• Receiving stream classifi ation
2. In order to establish the numeric tandard for each hardness-dependent metal of concern and for
each individual discharge,the Pe 't Writer must first determine what effluent and instream
(upstream)hardness values to u 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,t e permit writer may choose to do an initial evaluation using a
default hardness of 25 mg/L(Ca 03 or(Ca+Mg)). Minimum and maximum limits on the
hardness value used for water q lity calculations are 25 mg/L and 400 mg/L,respectively.
If the use of a default hardness v lue results in a hardness-dependent metal showing reasonable
potential,the permit writer conta is the Permittee and requests 5 site-specific effluent and
upstream hardness samples over period of one week.The RPA is rerun using the new data.
Page 2 of 4
Permit No. NC0024236
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 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 = f11
Ctotal 1 + { [K ] [Ssil+ai] [MI }
Where:
ss=in-stream suspended solids concentration [mg/1],minimum of 10 mg/L used,
and
Kpo and a=constants that express the equilibrium relationship between dissolved
and adsorbed forms of metals.A list of constants used for each hardness-dependent
metal can also be found in the RPA program under a sheet labeled DPCs.
4. The numeric standard for each metal of concern is divided by the default partition coefficient(or
site-specific translator)to obtain a Total Recoverable Metal at ambient conditions.
In some cases,where an EPA default partition coefficient translator does not exist(ie. silver),the
dissolved numeric standard for each metal of concern is divided by the EPA conversion factor to
obtain a Total Recoverable Metal at ambient conditions.This method presumes that the metal is
dissolved to the same extent as it was during EPA's criteria development for metals.For more
information on conversion factors see the June, 1996 EPA Translator Guidance Document.
5. The RPA spreadsheet uses a mass balance equation to determine the total allowable concentration
(permit limits)for each pollutant using the following equation:
Ca=(s7Q10+Ow)(Cwqs)—(s7Q10)(Cb)
Qw
Where: Ca=allowable effluent concentration(µg/L or mg/L)
Cwqs=NC Water Quality Standard or federal criteria(µg/L or mg/L)
Cb=background concentration: assume zero for all toxicants except NH3* (µg/L or mg/L)
Qw=permitted effluent flow(cfs,match s7Q 10)
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. NC0024236
QA=used in the equation to protect human health through the consumption of water,
fish,and shellfish from carcinogens
30Q2=used in the equation to protect aesthetic quality
6. The permit writer enters the most recent 2-3 years of effluent data for each pollutant of concern.
Data entered must have been taken within four and one-half years prior to the date of the permit
application(40 CFR 122.21). The RPA spreadsheet estimates the 95th percentile upper
concentration of each pollutant. The Predicted Max concentrations are compared to the Total
allowable concentrations to determine if a permit limit is necessary.If the predicted max exceeds
the acute or chronic Total allowable concentrations,the discharge is considered to show
reasonable potential to violate the water quality standard, and a permit limit(Total allowable
concentration)is included in the permit in accordance with the U.S. EPA Technical Support
Document for Water Quality-Based Toxics Control published in 1991.
7. When appropriate,permit writers develop facility specific compliance schedules in accordance
with the EPA Headquarters Memo dated May 10,2007 from James Hanlon to Alexis Strauss on
40 CFR 122.47 Compliance Schedule Requirements.
8. The Total Chromium NC WQS was removed and replaced with trivalent chromium and
hexavalent chromium Water Quality Standards.As a cost savings measure,total chromium data
results may be used as a conservative surrogate in cases where there are no analytical results
based on chromium III or VI. In these cases,the projected maximum concentration(95th%) for
total chromium will be compared against water quality standards for chromium III and
chromium VI.
9. Effluent hardness sampling and instream hardness sampling,upstream of the discharge, are
inserted into all permits with facilities monitoring for hardness-dependent metals to ensure the
accuracy of the permit limits and to build a more robust hardness dataset.
