Section 1. Facility Overview:
Gateway Village, LLC operates a groundwater remediation system with permitted
wastewater discharge of 0.05 MGD. The facility is designed to remove gasoline and
solvents and generates an intermittent discharge (discharge 7 days a week for varying
lengths of time). The maximum, monthly average discharge between April 2017 and
March 2020 was approximately 0.0384 MGD.
Per 2011 permit renewal factsheet: The site ground water was identified as being
impacted by petroleum and chlorinated solvents. Treated wastewater is discharged from
the treatment system to a storm drain which eventually flows into Irwin Creek via an
unnamed tributary. The unnamed tributary is considered a "zero' flow stream. The
ground water treatment operation consisted of a single collection sump and pump that
conveyed captured contaminated ground water intermittently to the treatment system
1200 gal collection tank. Once the collection tank was full, it was pumped at a maximum
rate of 50 GPM through bag -type particle filters, through replaceable GAC filters, and
through an effluent flow meter. Then the treated wastewater was discharged into the local
storm drain. With the extremely low flow from the sump and large storage capacity of the
collection tank this system did not run very often. The treatment system present operation
is to collect wastewater from multiple sumps, remove contaminates, and provide treated

wastewater as cooling tower make up, or if needed divert the treated wastewater to the
NPDES outfall.
Section 2. Compliance History (April 2014 — April 2020):
• No NODS, NOVs, or CPAs
• Passes all toxicity tests since January 2017

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.
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, 7Q 10 (the spreadsheet
automatically calculates the IQ 10 using the formula IQ 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, mjg/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(l+a)] [10-6] }
Where:
ss = in -stream suspended solids concentration [mg/1], minimum of 10 mg/L
used, and
Kpo and a = constants that express the equilibrium relationship between
dissolved and adsorbed forms of metals. A list of constants used for each
hardness -dependent metal can also be found in the RPA program under a
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) — (s7Q 10) (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.

Brianna,
I was talking with the owner representative today and the change in ownership happened in april 2020. Prior to that
time, Cousins property owned 51% of the permitted entity and Bank of America owned 49% of the permitted entity. In
april, BOA bought Cousins share of the permitted entity and now owns Charlotte Gateway Village, LLC in its entirety. The
current owner rep explained to me that this does not result in a new ownership, just new contact information. Do you
agree?
Thank you,
Rob Foster

Good afternoon Mr. Singleton,

Based on this application you submitted, it appears the owner of the facility has changed. As such, the Division requires
a completed Name and Ownership Change form to be submitted, along with all required documentation. This form can
be found on our website at https://deg.nc.gov/about/divisions/water-resources/water-quality-permitting/npdes-
wastewater/npdes-compliance-and-0 under the Reporting Forms section. Please submit all required information to the
address listed on the form. Once the Division determines all information has been received, the permit may be issued
to the new owner.
If additional people should be given signature authority relating to this permit, please fill out the Delegation of Signature

concerning this.
Thank you,
