1.0 BACKGROUND
The project is associated with city street rights-of-way in Charlotte along portions of Baxter Street,
South McDowell Street, Morehead Street, Oriole Street, and Lexington Avenue. Adjoining
properties appear to have existed as urban areas since 1929, generally developed with a mix of
commercial, residential, and undeveloped parcels. Groundwater has been impacted with trace
concentrations of chlorinated solvents from a NC Brownfields Site. De-watering and treatment
activities are ongoing,but treatment and discharge activities propose to terminate following
construction.
Previous site assessments indicate that converging contaminant plumes having impacted soils
and groundwater beneath Baxter Street. These plumes likely relate to historic dry-cleaning
operations (chlorinated solvents) and underground storage tank releases. Investigations
beginning in 1997 have consistently detected contaminants above both groundwater standards
[I5A NCAC 02L.0202] and surface-water quality standards [15A NCAC 02B]. The Permittee
has attached site plans indicating the location of groundwater monitoring wells providing data
to the project.

2.0 PROJECT DESCRIPTION
Charlotte Water(Charlotte) continues to construct new sanitary sewer line extensions along
portions of Baxter Street and McDowell Street by micro-tunneling. Groundwater from access pits
and boreholes is pumped south of the excavation area to a treatment system, ultimately discharging
into a UT to Little Sugar Creek.
Contaminants of Concern (COCs). The Division previously established a list of organic and
inorganic COCs reflecting previous Brownfields investigations and the permit application's table
Summary of Detection [Pace Analytical Services, LLC].
The Applicant continues to discharge to a UT to Little Sugar Creek(see Site Vicinity Map). Because
this outfall discharges under zero flow receiving stream conditions [30Q2 and 7Q 10 =0.0 cfs], the
Division affords no dilution,per current permitting guidance statewide. Permit limits therefore
reflect each COC's surface water quality standard, if any. DWR applies the standard, if present, as
both acute and chronic limits [see section A. (1.)].
3.0 EFFLUENT DATA REVIEW—EVALUATION OF TREATMENT PERFORMANCE
Whole Effluent Toxicity (WET) Testing—considering a potential discharge daily [six(6)days/
week],DWR recommends WET testing Acute, Monitor Only [TAA6Cl; 2/Monthly (Pimephales
promelas) 48-hour static test. [See Section A. (2)]. WET-test samples shall be collected
concurrently with other effluent samples as appropriate to monitoring frequency.
Reasonable Potential Analyses (RPAs)—DWR performed RPAs on chlorinated solvents, metals,
and other volatile organic compounds to determine each potential to exceed its water quality
standards, as applicable (See Fact Sheet). A review of treated effluent to date suggests that
Charlotte's current treatment system is adequate to protect surface water quality in that DWR finds
no infractions of permit limits or monitoring conditions during the previous permit cycle. Although
we find no reasonable potential, DWR remains concerned about unpredictable COC
concentrations in traveling excavations requiring dewatering.
Renewal Rationale -- DWR understands that Charlotte continues to advance traveling excavations
requiring dewatering along multiple city blocks. Because of the traveling nature of these
excavations, there remains the potential to encounter renewed concentrations of COCs known to
be present as identified by previous NC Brownfields studies and by Charlotte site investigations.
Acknowledging unpredictable contaminant concentrations, the Division will therefore require for
renewal the same effluent parameters, limits, and monitoring conditions listed in Charlotte's
previous permit [see section A. (1.)]. These include but are not limited to:
• Total Purgeable Organic Compounds, EPA 624.1
• Base-Neutral Acids (Semi-Volatile Organics), Methods and 625.1
• Total PAHs, EPA Method 8270
• Polychlorinated biphenyls (PCBs), EPA Method 8280A

5.0 JPA MET LS EVALUATION— for TOTAL HARDNESS
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.
Fact Sheet
Charlotte Water-Sewer Extension-Renewal NPDES Permit NCO089923
Page 4 of 7

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 an RPA on the Freshwater hardness-dependent metals the Permit Writer
compiles the following information:
• Critical low flow of the receiving stream, 7Q10 (the spreadsheet automatically
calculates the 1 Q 10 using the formula 1 Q 10 =0.843 (s7Q 10, cfs) 0.993
• Effluent hardness and upstream hardness, site-specific data is preferred
• Permitted flow
• Receiving stream classification
2. In order to establish the numeric standard for each hardness-dependent metal of concern
and for each individual discharge, the Permit Writer must first determine what effluent and
instream (upstream)hardness values to use in the equations.
The permit writer reviews DMR's, Effluent Pollutant Scans, and Toxicity Test results for
any hardness data and contacts the Permittee to see if any additional data is available for
instream hardness values,upstream of the discharge.
If no hardness data is available, the permit writer may choose to do an initial evaluation
using a default hardness of 25 mg/L (CaCO3 or(Ca+Mg)). Minimum and maximum
limits on the hardness value used for water quality calculations are 25 mg/L and 400 mg/L,
respectively.
If the use of a default hardness value results in a hardness-dependent metal showing
reasonable potential, the permit writer contacts the Permittee and requests 5 site-specific
effluent and upstream hardness samples over a period of one week. The RPA is rerun using
the new data.
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)x(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.
Fact Sheet
Charlotte Water—Sewer Extension—Renewal NPDES Permit NC0089923
Page 5 of 7

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
Ctotal I + { [Kp,,] [SS(l`)] [10-6]
Where:
ss=in-stream suspended solids concentration [mg/1],minimum of 10 mg/L used,
and Kpo and a=constants that express the equilibrium relationship between
dissolved and adsorbed forms of metals.A list of constants used for each hardness-
dependent metal can also be found in the RPA program under a sheet labeled DPCs.
4. The numeric standard for each metal of concern is divided by the default partition
coefficient(or site-specific translator) to obtain a Total Recoverable Metal at ambient
conditions.
In some cases, where an EPA default partition coefficient translator does not exist(ie.
silver), the dissolved numeric standard for each metal of concern is divided by the EPA
conversion factor to obtain a Total Recoverable Metal at ambient conditions. This method
presumes that the metal is dissolved to the same extent as it was during EPA's criteria
development for metals. For more information on conversion factors see the June, 1996
EPA Translator Guidance Document.
5. The RPA spreadsheet uses a mass balance equation to determine the total allowable
concentration(permit limits) for each pollutant using the following equation:
Ca= (s7Q10+ Qw (�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 s7Q 10 may be incorporated as applicable:
IQ 10 =used in the equation to protect aquatic life from acute toxicity
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
Fact Sheet
Charlotte Water—Sewer Extension—Renewal NPDES Permit NCO089923
Page 6 of 7

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.
10. Hardness and flow values used in the Reasonable Potential Analysis for this permit

Mecklenburg County
To Mr. Deal:
The Division of Water Resources (the Division) hereby issues the attached NPDES permit for
the subject facility. We issue this permit pursuant to the requirements of North Carolina General
Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S.
Environmental Protection Agency dated October 15, 2007, or as subsequently amended.
RECEIVING STREAM EVALUATION
Charlotte Water's application for discharge provides historic stream-flow data for Little Sugar
Creek mainstem—not the UT to Little Sugar Creek where the application initially located the
outfall. Subsequent correspondence with the USGS provided stream data for the UT also.
However, these data are moot considering any discharge to a storm-sewer inlet affords no
dilution. Both Little Sugar Creek and its UT are currently classified C; these waterbodies located
within the Catawba River Basin. Little Sugar Creek is listed as impaired[2018 North Carolina
303 (d) List]. Stream impairments include:
• Fecal Coliform
• Turbidity limit [< 50 NTU].
• Dissolved Oxygen [daily average not< 5 mg/L; instantaneous
value not<4 mg/L during 7Q10 stream-flow conditions.
EVALUATION of PROPOSED DISCHARGE
Contaminants of Concern (COCs). The Division established a list of organic COCs reflecting
the table Summary of Detection provided with the application [Pace Analytical Services, LLC,
page 4 of 38]. However, while previous soil and groundwater analyses considered potential
organic contaminants, there are no data to date to assess the concentration of metals. DWR
therefore has added monitoring for a suite of metals (see permit Section A. (1.)]. It follows that

effluent Total Hardness and the receiving stream Total Hardness (upstream of the outfall) must
also be established in compliance with EPA guidelines for evaluating metals in dissolved
fraction. Finally, we have added Quarterly monitoring [see permit section A. (L)] as
comprehensive suites to spot-check for:
• Total Purgeable Organic Compounds, EPA 624
• Base-Neutral Acids (Semi-Volatile Organics), EPA Method 625
• Total PAHs, EPA Method 8270
• Polychlorinated biphenyls (PCBs), EPA Method 8280A
ESTABLISHING PERMIT LIMITS UNDER ZERO-FLOW CONDITIONS
Charlotte Water proposes to discharge to established storm-sewer inlets along the rights-of-way
to the Baxter and McDowell Streets discharging to the UT to Little Sugar Creek(see revised
application, Vicinity Map). Because these outfalls discharge to a storm-sewer inlet, the Division
must assume zero flow receiving-stream conditions offering no dilution,per current permitting
guidance. Permit limits therefore reflect each given COC's surface water quality standard. DWR
applied each standard as both acute and chronic limits,per EPA Guidance [see section A. (1.)].
Reasonable Potential Analyses RDAs)were not conducted on the current database because there
are currently no post treatment analytical data; analyses to date consist of samples untreated for
discharge collected sporadically during site assessment.
ENGINEERING ALTERNATIVES ANALYSIS (EAA)
The Applicant presented an Engineering Alternatives Analysis (EAA), as required of new
discharges, concluding that a surface-water discharge is the most viable discharge alternative
based on cost(see permit application, Table 1 EAA Cost Analysis). The Division concurs with
this conclusion.
Whole Effluent Toxicity (WET) Testing—to protect the environment considering a
potential discharge daily [six (6) days per week], DWR recommends WET testing Acute,
Monitor Only; 2/Monthly (Pimephales promelas) 48-hour static test. [See Section A.
(2)], consistent with similar discharge activities statewide. WET-test samples shall be
collected concurrently with other effluent samples as appropriate to monitoring frequency
to assist in evaluating toxicity.
eDMR Submittals: Federal regulations require electronic submittal of all discharge monitoring
data and program reports [See Special Condition A. (1)]. If you have filled out and submitted to
DWQ an electronic signature agreement, you are no longer required to submit DMR forms as
back-up to the eDMR.

Dissolved Metals Standards. EPA approved NC 2015-2019 Water Quality Standard(WQS)
Triennial Review to include new chronic and acute dissolved standards for most metals. Further,
the freshwater standards for several metals are expressed as a dissolved fraction of the metal, and
seven metals require hardness-dependent equations. As a result, the NPDES Permitting Unit will
need both site-specific effluent hardness and receiving-stream hardness data upstream.
This permit authorization to discharge shall expire at midnight on June 30, 2022. If the
Permittee intends to continue discharge beyond the term of this permit, a renewal application
must be submitted no later than January 31, 2021 (180 days prior to permit expiration).
If any parts, measurement frequencies, or sampling requirements contained in this permit are
unacceptable, you have the right to an adjudicatory hearing,upon written request submitted within
thirty (30) days after receiving this letter. Your written petition request must conform to Chapter
150B of the North Carolina General Statutes, and you must file it with the office of Administrative
Hearings, 6714 Mail Service Center, Raleigh,North Carolina 27699-6714. Unless such a written
demand is made, this permit shall remain final and binding.
This permit is not transferable except after notifying the Division of Water Resources. The
Division may modify, or revoke and reissue this permit. Please note that this permit does not
affect your legal obligation to obtain other permits that may be required by the Division of Water

A. (3.) ELECTRONIC REPORTING OF DISCHARGE 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)]
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. The eDMR system may be
accessed at: https://deq.nc.gov/about/divisions/water-resources/edmr.
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
following address:
NC DEQ/Division of Water Resources/Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh,North Carolina 27699-1617
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.

NPDES Electronic Reporting Rule—Phase 2 Extension: EPA is proposing to extend the Phase 2
deadline from December 21, 2020 until at least December 21, 2023. The current compliance date
will be extended if the implementation date is extended as a final regulation change in the federal
register.
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(l)(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 designated entity
for receiving electronic NPDES data [see 40 CFR 127.2(b)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for
each type of electronic submission and for each state. Instructions on how to access and use the
appropriate electronic reporting tool will be available as well. Information on EPA's NPDES
Electronic Reporting Rule is found at: hgps://www.federalre ig ster.gov/documents/2015/10/22/2015-
24954/national-pollutant-discharge-elimination-system-npdes-electronic-reporting-rule
Electronic submissions must start by the dates listed in the "Reporting Requirements" section above.
3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to
the Division. Requests for temporary electronic reporting waivers must be submitted in writing to
the Division for written approval at least sixty(60) days prior to the date the facility would be
required under this permit to begin submitting monitoring data and reports. The duration of a
temporary waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring data
and reports shall be submitted electronically to the Division unless the permittee re-applies for and is
granted a new temporary electronic reporting waiver by the Division. Approved electronic reporting
waivers are not transferrable. Only permittees with an approved reporting waiver request may submit
monitoring data and reports on paper to the Division for the period that the approved reporting
waiver request is effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found on

2.0 PROJECT DESCRIPTION
The Applicant proposes to construct new sanitary sewer line along portions of Baxter Street and
McDowell Street by micro-tunneling. Groundwater from access pits and boreholes will be pumped
out and treated before discharging directly into a UT to Little Sugar Creek (locations variable as
storm-sewer outfalls to the UT),part of the Sugar Creek watershed. Dewatering and treatment
activities are estimated to last approximately twelve 12)months. The collection of groundwater, its
treatment, and discharge will be terminated once construction activities are completed below the

The Subject Property consists of roads and associated rights-of-way along portions of Baxter
Street, South McDowell Street, Morehead Street, Oriole Street, and Lexington Avenue. Adjoining
properties appear to have existed as an urban area, generally developed with a mix of commercial,
residential and undeveloped parcels since at 1929.

Previous site assessments indicate that two contaminant plumes have impacted soils and
groundwater beneath Baxter Street. These plumes likely relate to historic dry-cleaning
operations (chlorinated solvents) and underground storage tank releases. Investigations as early
as 1997 have consistently detected several constituents above both groundwater standards [15A
NCAC 02L.0202] and surface-water standards [15A NCAC 02B]. The attached site plan
indicates the location of groundwater monitoring wells providing data to the project.
3.0 RECEIVING STREAM EVALUATION
The application for discharge provides historic stream-flow data for Little Sugar Creek mainstem—
not the UT to Little Sugar Creek where the Applicant has initially located the outfall. Subsequent
correspondence with the USGS and the Applicant, Bruce Reilly(Civil & Environmental
Consultants, Inc., 23Jul2020)provided concurrence and stream data for the UT. However, these
stream-flow data are moot considering any discharge to a storm-sewer inlet affords no dilution (see
below 4.0). Both Little Sugar Creek and its UT are currently classified C; these waterbodies
located within the Catawba River Basin. Little Sugar Creek is listed as impaired[2018 North
Carolina 303 (d) List]. The total maximum daily loads (TMDLs) include:
• Fecal Coliform
• Turbidity limit [< 50 NTU].
• Dissolved Oxygen [daily average not< 5 mg/L; instantaneous
value not<4 mg/L during 7Q10 stream-flow conditions.
4.0 EVALUATION of PROPOSED DISCHARGE
Contaminants of Concern (COCs). The Division established a list of organic COCs reflecting the
table Summary of Detection [Pace Analytical Services, LLC,page 4 of 38] provided with the
application. However, while previous soil and groundwater analyses considered potential organic
contaminants, there are no data to date to assess the concentration of metals. DWR therefore has
added monitoring for a suite of metals (see permit Section A. (1.)]. It follows that Total Hardness
of the effluent and the receiving stream (upstream of the outfall)must also be established in
compliance with EPA guidelines for evaluating metals in dissolved fraction [see below, 7.0].
Finally, we have added Quarterly monitoring [see permit section A. (L)] as comprehensive suites
to spot-check for:
• Total Purgeable Organic Compounds, EPA 624
• Base-Neutral Acids (Semi-Volatile Organics), Methods and 625
• Total PAHs, EPA Method 8270
• Polychlorinated biphenyls (PCBs), EPA Method 8280A
5.0 ESTABLISHING PERMIT LIMITS
The Applicant proposes to discharge to established storm-sewer inlets along the rights-of-way to
the Baxter and McDowell Streets discharging to the UT to Little Sugar Creek(see revised location,
Vicinity Map). Because these outfalls discharge to a storm-sewer inlet, the Division will assume
zero flow receiving-stream conditions offering no dilution per current permitting guidance. Permit

limits therefore reflect each given COC's surface water quality standard. DWR applied the
standard as both acute and chronic limits [see section A. (1.)].
Reasonable Potential Analyses (RPAs)were not conducted on the current database because there
are no post treatment analytical data; analyses to date consist of samples untreated for discharge
collected sporadically during site assessment.
6.0 ENGINEERING ALTERNATIVES ANALYSIS (EAA)
The Applicant presented an Engineering Alternatives Analysis (EAA), as required of new
discharges, concluding that a surface-water discharge is the most viable discharge alternative based
on cost(see permit application, Table 1 EAA Cost Analysis). The Division concurs with this
conclusion.
Whole Effluent Toxicity (WET) Testing—to protect the environment considering a potential
discharge daily [six(6)days/week],DWR recommends WET testing Acute, Monitor Only; 2/Monthly
(Pimephales promelas) 48-hour static test. [See Section A. (2)]. WET-test samples shall be
collected concurrently with other effluent samples as appropriate to monitoring frequency.
7.0 METALS EVALUATION — for TOTAL HARDNESS
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
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.
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)x(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.

Page 5

DocuSign Envelope ID:A07D8D4B-ElF7-4650-AF8B-44DF8501E045
EPA default partition coefficients or the"Fraction Dissolved"converts the value for
dissolved metal at laboratory conditions to total recoverable metal at in-stream
ambient conditions. This factor is calculated using the linear partition coefficients
found in The Metals Translator: Guidance for Calculating a Total Recoverable
Permit Limit from a Dissolved Criterion (EPA 823-B-96-007, June 1996)and the
equation:
Cdiss_— 1
Ctotal I + { [Kp,,] [ss(1+a)] [10-6]
Where:
ss=in-stream suspended solids concentration [mg/1],minimum of 10 mg/L used,
and Kpo and a=constants that express the equilibrium relationship between
dissolved and adsorbed forms of metals. A list of constants used for each hardness-
dependent metal can also be found in the RPA program under a sheet labeled DPCs.
4. The numeric standard for each metal of concern is divided by the default partition
coefficient(or site-specific translator) to obtain a Total Recoverable Metal at ambient
conditions.
In some cases, where an EPA default partition coefficient translator does not exist(ie.
silver), the dissolved numeric standard for each metal of concern is divided by the EPA
conversion factor to obtain a Total Recoverable Metal at ambient conditions. This method
presumes that the metal is dissolved to the same extent as it was during EPA's criteria
development for metals. For more information on conversion factors see the June, 1996
EPA Translator Guidance Document.
5. The RPA spreadsheet uses a mass balance equation to determine the total allowable
concentration(permit limits) for each pollutant using the following equation:
Ca= (s7Q 10+ Qw (�Cwgs)-s7Q10) (Cb)
QW
Where: Ca=allowable effluent concentration (µg/L or mg/L)
Cwqs =NC Water Quality Standard or federal criteria(µg/L or mg/L)
Cb=background concentration: assume zero for all toxicants except NH3* (µg/L or
mg/L)
Qw=permitted effluent flow(cfs, match s7Q 10)
s7Q 10= summer low flow used to protect aquatic life from chronic toxicity and
human health through the consumption of water, fish, and shellfish from
noncarcinogens (cfs)
* Discussions are on-going with EPA on how best to address background
concentrations
Flows other than s7Q 10 may be incorporated as applicable:
IQ 10 =used in the equation to protect aquatic life from acute toxicity
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.
10. Hardness and flow values used in the Reasonable Potential Analysis for this permit
included:

1.0 BACKGROUND
The Subject Property consists of roads and associated right-of-ways along portions of Baxter
Street, South McDowell Street, Morehead Street, Oriole Street, and Lexington Avenue. The
adjoining properties appear to have existed as an urban area, generally developed with a mix of
commercial, residential and undeveloped parcels since at 1929. Previous assessments indicate that
two contaminant plumes have impacted soils and groundwater beneath Baxter Street related to
historic dry cleaning operations (chlorinated solvents) and underground storage tank release.
Investigations as early as 1997 have consistently detected several constituents above the 15A
NCAC 02L.0202 groundwater standards: carbon tetrachloride(CT),tetrachloroethene(PCE),and
trichloroethene (TCE). CEC performed groundwater sampling in March 2019 and found the 15A
NCAC 02L.0202 groundwater and the 15A NCAC 02B surface water standard exceedances for
PCE in wells MW-3s, MW-6, and MW-8s and toluene in well MW-5s (analytical lab results are
attached). The attached site plan indicates the location of the monitoring wells in relation to the
project location.
2.0 PROJECT DESCRIPTION
The project will consist of the construction of a new sanitary sewer line along portions of Baxter
Street and McDowell Street by micro-tunneling. Groundwater from access pits and boreholes will
be pumped out and treated before discharging directly into Little Sugar Creek, part of the Sugar
Creek Watershed. Dewatering and treatment activities are estimated to last approximately twelve
(12) months. The collection, treatment, and discharge of treated groundwater will be terminated
once construction activities performed below the groundwater table are completed.

Little Sugar Creek is classified as a Class C (fishable/swimmable) water located within the
Catawba River Basin and is listed as an impaired waterway on the North Carolina 303(d)List.The
total maximum daily limits (TMDLs) include a fecal coliform limit of less than 9.4x1012 cfu/100
mL and a turbidity limit of less than of 50 NTU. There is also a TMDL for dissolved oxygen of no
less than a daily average of 5 mg/L and instantaneous value of 4 mg/L during 7Q10 stream flow
conditions.
The proposed groundwater treatment system consists of a 1,100 gallon surge tank, two parallel
particle filters, two 1,000 pound carbon vessels connected in series, and ancillary piping,
instrumentation,and valving.The system has a flow capacity of 50 gpm and will have an operating
flow rate of 25 gpm. Groundwater generated by dewatering activities will be pumped to the surge
tank to equalize flow and settle larger suspended solids.Pumps 1 and 2 will transfer the supernatant
through the particle filters to the carbon vessels that contain virgin coconut carbon. CEC
anticipates that the treatment system will sufficiently remove organics and turbidity to levels below
detection. The process flow diagram is included as an attachment. The proposed location of the
treatment system and outfall is shown on the attached site plan.
3.2 NON-MUNICIPAL FLOW PROJECTION
Based on similar construction projects in the uptown Charlotte area,the estimated discharge flow
from the treatment system will be 25 gallons per minute(36,000 gpd).
3.3 FEASIBILITY EVALUATION OF ALTERNATIVES
In accordance with 15A NCAC 2H.0105(c)(2), CEC evaluated the technical and economic
feasibility of wastewater disposal alternatives referenced in the Engineering Alternatives Analysis
(EAA)Guidance document.
3.3.1 Connection to Existing Wastewater Treatment System
Based on a review of the City of Charlotte Sewer Use Ordinance, the municipal treatment plants
owned and operated by the City do not accept groundwater discharges per Section 23-79 (b)(14).
Additionally, CEC approached DART, a Charlotte-based company specialized in waste disposal,
and they stated that disposal and treatment of groundwater would cost$0.40 per gallon. Based on
the projected flow rate and anticipated duration of dewatering activities, the disposal cost would
be approximately$6.5 million deeming this alternative cost prohibitive.

3.3.2 Land Application and Infiltration Galleries
Due the limited land available adjacent to the project site and setback requirements, land
application and infiltration galleries are technically infeasible as wastewater disposal methods.
Nearby properties are currently valued a $4 -10 million per acre making these options cost
prohibitive (supporting documentation attached). A table detailing the capital and operating costs
for these options is included as an attachment.
3.3.3 In-Situ Remediation Wells
Due the limited land available adjacent to the project site,the installation of off-site injection wells
is technically infeasible as wastewater disposal method. Nearby properties are currently valued a
$4 -10 million per acre making this option cost prohibitive (supporting documentation attached).
A table detailing the capital and operating costs for these options is included as an attachment.
