1. Background
Catalyst Capital Partners is redeveloping an approximately 0.86-acre property located at 1600 & 1614
Camden Road and 109 & 115 West Park Avenue in Charlotte, Mecklenburg County, NC. The property
is a NC Brownfields site. The subject property is currently developed with a single -story restaurant
building (approximately 3,600 sqft) and a two-story office building (approximately 6,947 sqft). The
remaining portions of the subject property consist of paved parking areas and landscaped areas. Catalyst
Capital Partners plans to construct a 291-Units, 29-Story tower, that will include apartments, parking
deck, retail space, restaurant space, and office space.
2. Project Description
During construction, Camden Exchange proposes to collect groundwater from the construction areas
where excavations may intersect the water table using lateral drain and/or sumps and during the drilling
of deep foundation systems. The treatment system will include a 18,000-gallon frac tank for settling and
grit removal, followed by a 1,000-gallon surge/mixing tank, followed by two particulate filters in series,
followed by two 1,000-pound carbon vessels in series. Stormwater drop basins are located on the subject
property and flow in subsurface piping to a discharge point on an unnamed tributary to Irwin Creek,
approximately 2,600-ft northwest of the subject property. The dewatering activity is expected to occur
over a period of approximately one year.
3. Receiving Stream Evaluation
Irwin Creek and its UTs by association are currently classified C waterbodies located within the
Catawba River Basin. Irwin Creek is listed by the Division as impaired [2022 North Carolina 303 (d)
List] for Benthos and Fish Community.

In accord with statewide NPDES permitting guidance, any discharge to a storm -sewer inlet is deemed
zero flow and therefore may afford no dilution to the effluent [15A NCAC 0213.0206 (d)].
4. DWR Evaluation of Proposed Discharge
Contaminants of Concern (COCs). The Division considered a list of COCs as site -assessment data
provided by the Applicant as analytes "believed to be present" [see application package for table of
Summary of Detection and details provided by Pace Analytical Services, LLC]. DWR has added
monitoring Monthly for these organic and inorganic analytes (see permit Section A. (1.)). Metals require
Fact Sheet - NPDES Permit NCO090115
Page 2 of 9

effluent monitoring for Total Hardness to established compliance with EPA guidelines for metals in
dissolved fraction [see 9. EPA Metals Evaluation — for Total Hardness below].
In addition to analytes "believed to be present," DWR has added Monthly monitoring for suites of
analytes as a comprehensive spot-check for organic compounds:
• Total Purgeable Organic Compounds, EPA 624.1
• Base -Neutral Acids (Semi -Volatile Organics), EPA Method 625.1
5. Establishing Compliance & Permit Limits
The Applicant proposes to discharge from an onsite Groundwater Treatment System to an established
storm -sewer inlet onsite. Because this outfall discharges to a storm -sewer inlet, the Division will assume
zero flow receiving -stream conditions offering no dilution, per NPDES permitting guidance statewide.
Permit limits therefore reflect Contaminants of Concern (COCs) based on analytes identified by the
Applicant as "known to be present" [See EPA Application form 2D].

6. Engineering Alternatives Analysis (EAA)
USGS made a determination that this unnamed tributary to Irwin Creek is a zero -flow stream. For
purposes of effluent limitations, a 7Q 10 of zero and an instream waste concentration (IWC) of 100%
will apply.
Communication with DWR's Modelling and Assessment Branch indicated that there are no impending
TMDLs for Irwin Creek.
Communication with the NC Wildlife Resource Commission indicated that there are no current records
of state or federally listed rare, threatened, or endangered species in Irwin Creek.
The applicant provided information on population growth of Mecklenburg County and concluded that the
expected population increase will not increase the anticipated flow rate as it's not dependent on population size.
The application also considered other technologically feasible alternatives as the following:
• Land application: not feasible due to land constraints as this site is in the urban area of Charlotte
• Connecting to an existing WWTP: the City of Charlotte prohibit the discharge of groundwater to
its POTW, no private WWTP nearby either
• Wastewater reuse: not feasible because the Brownfields Agreement for this property is expected
to prohibit the reuse of extracted groundwater
No Present Value of Cost Analysis was performed due to the above -mentioned reasons.
The applicant has submitted Local Government Review Form to the City of Charlotte and Mecklenburg
County but hasn't received a response.
Charlotte -Mecklenburg Storm Water Services approves the discharge of treated groundwater from this
remediation site.
7. Comment Received On Draft Permit
No comment received on draft permit.
8. Changes To Final Permit

9. EPA 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
Fact Sheet - NPDES Permit NC0090115
Page 4 of 9

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.
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.
Fact Sheet - NPDES Permit NC0090115
Page 6 of 9

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.
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(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
Fact Sheet - NPDES Permit NC0090115
Page 7 of 9

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) (Cwqs) - (s7Q 10) (Cb)
Qom'
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.
