QUALIFIERS
Project: Carson&Tryon
Pace Project No.: 92569749
DEFINITIONS
DF-Dilution Factor,if reported,represents the factor applied to the reported data due to dilution of the sample aliquot.
ND-Not Detected at or above adjusted reporting limit.
TNTC-Too Numerous To Count
J-Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL-Adjusted Method Detection Limit.
PQL-Practical Quantitation Limit.
RL-Reporting Limit-The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S-Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270.The result for each analyte is
a combined concentration.
Consistent with EPA guidelines,unrounded data are displayed and have been used to calculate%recovery and RPD values.
LCS(D)-Laboratory Control Sample(Duplicate)
MS(D)-Matrix Spike(Duplicate)
DUP-Sample Duplicate
RPD-Relative Percent Difference
NC-Not Calculable.
SG-Silica Gel-Clean-Up
U-Indicates the compound was analyzed for,but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting.Therefore,calculated parameters that are typically reported as
"Total"may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited.Contact your Pace PM for the current list of accredited analytes.
TNI-The NELAC Institute.
ANALYTE QUALIFIERS
D3 Sample was diluted due to the presence of high levels of non-target analytes or other matrix interference.
IL This analyte exceeded secondary source verification criteria low for the initial calibration.The reported results should be
considered an estimated value.
J Analyte detected below the reporting limit,therefore result is an estimate.This qualifier is also used for all TICs.
L2 Analyte recovery in the laboratory control sample(LCS)was below QC limits. Results for this analyte in associated
samples may be biased low.
MO Matrix spike recovery and/or matrix spike duplicate recovery was outside laboratory control limits.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample(LCS)recovery.
N2 The lab does not hold NELAC/TNI accreditation for this parameter but other accreditations/certifications may apply.A
complete list of accreditations/certifications is available upon request.
R1 RPD value was outside control limits.
S4 Surrogate recovery not evaluated against control limits due to sample dilution.
v1 The continuing calibration verification was above the method acceptance limit.Any detection for the analyte in the
associated samples may have a high bias.

Re: NPDES permit application -request to discharge into the City of Charlotte municipal
stormwater system at 1102, 1106& 1018 South Tryon Street
Division of Water Resources:
Regarding Crescent Acquisitions, LLC's request (submitted by ECS Southeast, LLP) in their
NPDES permit application to discharge treated water from a remediation system at the
above-referenced location into Charlotte's stormwater system, Charlotte Mecklenburg
Storm Water Services (CMSWS) approves the discharge.
CMSWS would like to make the permittee and NC DEQ aware of the following
considerations and information:
• CMSWS reserves the right to access,inspect,sample,and review documentation
regarding the groundwater treatment system at any time.
• In the event of an illicit discharge,bypass, or exceedance of permit discharge limits,
Crescent Acquisitions, LLC or its consultant shall immediately notify CMSWS and
immediately implement corrective actions.
• CMSWS reserves the right to rescind approval of discharge to the City of Charlotte's
MS4 for due cause including gross improper operation of the system, an established
trend of discharge limit exceedances,failure to provide notification of illicit
discharges and system bypasses,and similar reasons.
• CMSWS does not guarantee adequate capacity is available to permitted dischargers
to keep any property or street free of water or harm as a result of this discharge. It is
recommended that if discharge flows are anticipated to be high, the discharger
should avoid discharging during wet weather.
• CMSWS takes no responsibility for backflows from the public drainage system into
the permitted discharger's system.
If you have any questions,please contact Andrew DeCristofaro at [phone].

B. Project Description
o Crescent Acquisitions, LLC is redeveloping an approximately 2.77-acre property
located at 1102, 1106, and 1018 South Tryon Street in Charlotte, Mecklenburg
County,North Carolina. According to the Mecklenburg Property Ownership and
Land Records Site (POLARIS), the Parcel Identification Numbers (PIN)
are:07305302, 07305303, 07305304, and 07305305. The parcels are owned by
CC TREA Carson Station, LLC and C/O Crescent Communities, LLC
o The subject property is currently developed with an approximate 2,100 square-
foot two-story building that was constructed in 1956 Crescent Acquisitions, LLC
plans to construct a 7-story multi-family structure, 8-story concrete podium
parking garage with 21 stories of Office above the parking garage,and a 13-story
hotel.
o Groundwater monitoring of four monitoring wells was performed in October
2021.A figure with the location of the wells is included in Appendix A. Benzene,
chloroform, 1,2-dichloroethane, diisopropyl ether, and naphthalene were
detected on groundwater samples collected in the subject property. The
detected concentrations of benzene (maximum concentration of 28.5
micrograms per liter[µg/L))and, 1,2-dichloroethane(maximum concentration
of 10.3 µg/L), exceed their respective North Carolina groundwater standards.
The table with the analytical results is in Appendix A.
o The proposed discharge will flow to Irwin Creek via the Charlotte-Mecklenburg
County stormwater system. ECS reviewed the NCDEQ Stream Classification
Map on March 24, 2022. This map may be accessed at:
https://ncdenr.maps.arcgis.com/apps/webappviewer/index.html?id=6e125a
d7628f494694e259c80dd64265. Appendix B include a screen shot of this map
with the discharge point on Irwin Creek. Irwin Creek at the point where this
1

stream enters is classified as Class C.
o For the organic compounds detected during the October 2021 monitoring
event, ECS identified surface water standards for Class C waters for benzene(51
ug/I [based on fish consumption]), diisopropyl ether (20,000 ug/L based on
aquatic life and secondary recreation), and naphthalene (12 ug/L based on
aquatic life and secondary recreation). None of the compounds detected during
the December 2021 monitoring event exceeded the indicated surface water
standards.
o During construction,Crescent Acquisitions,LLC proposes to collect groundwater
from the construction areas where excavations may intersect the water table
using lateral drains and/or sumps and during the drilling of deep foundation
systems. Groundwater encountered during construction will discharge to an
18,000-gallon settling/holding tank equipped with overflow and underflow
weirs. A float-actuated pump will move water from the 18,000-gallon
settling/holding tank to a 1,000-gallon polyethylene surge tank.
Two 3-horsepower centrifugal pumps will be located downstream of the surge
tank to move water through two particulate bag filter housings plumbed in
parallel configuration; through two 1,000-pound granular activated carbon
(GAC) vessels plumbed in series configuration; through an inverted "U" loop
with a siphon break; through a magnetic flow meter with totalizer; and then
through a discharge line to a drop inlet to the municipal stormwater system.
The surge tank will be outfitted with a 3-level float assembly to provide data to
the PLC. The PLC will be programmed to activate one pump when the lowest
float is actuated and the second pump when the next float is actuated (so both
pumps will run simultaneously). The highest float will actuate an alarm
condition and will notify the operator via telemetry.
The two particulate bag filters housings will be 32-inch with 3-bolt covers. Filter
size is anticipated to be 10 to 25 microns. The filter housings will be plumbed
and valved such that one or both may be on line at a given time and to provide
a means to change out bag filters without taking system off line.
The two GAC vessels will each contain approximately 1,000 pounds of virgin
coconut carbon with a 12 by 40 mesh size. The vessels will be plumbed and
valved such that one or both may be online at a given time and to provide a
means to change out GAC media without taking system off line. In addition,the
plumbing and valving will be such to permit backwashing of the vessels.
Appendix C is a Process and Instrumentation Diagram (PID) showing the main
components of the proposed water treatment system, except for the 18,000-
gallon settling/holding tank and associated pump and controls.
Stormwater drop basins are located on the subject property and flow in
subsurface piping to a discharge point on the Irwin Creek, approximately 4,331-
feet at a location adjacent to an on-ramp from West Morehead St onto 1-77
2

North at latitude 35.229 north and longitude 80.859 west (Figure 1 and Figure
2).
o During construction, it is expected that groundwater may be encountered
during the construction of deep foundation systems. The construction
dewatering activity is expected to occur over a period of approximately one
year.
The Engineering Alternatives Analysis (EAA)guidance(revised March 2022) indicates that four
steps are to be followed in evaluating alternatives. The following paragraphs summarize these
steps.
STEP 1-DETERMINE IF THE PROPOSED DISCHARGE WILL BE ALLOWED
➢ Zero flow stream restrictions (15A NCAC 2B .0206[d][(2)) apply to oxygen-consuming
waste in zero-flow streams.
➢ The United States Geological Survey (USGS) evaluation does not indicate a
previous low-flow determination for the discharge point. No USGS discharge
records are known to exist for this point of interest. A copy of an email from
the USGS regarding stream flow characteristics is attached as Appendix D.
➢ Receiving stream classification restrictions (e.g., ORW, WS, SA, NSW, and HQ class waters
have various discharge restrictions or require stricter treatment standards).
o ECS determined that the stream classification for Irwin Creek is Class C by
reviewing data on NCDEQ's stream classification webpage on March 23, 2022.
Therefore, restrictions based on stream classification are not applicable.
Appendix B includes a screenshot NCDEQ's stream classification webpage.
➢ Basinwide Water Quality Plans. These basin-specific plans list NPDES permitting
strategies that may limit wastewater discharges to particular streams within the basin
due to lack of stream assimilative capacity,etc.
o ESC reviewed the 2007 final draft basin specific water quality plan for the
Catawba River Basin found through the NCDEQ website at
https://files.nc.gov/ncdeq/Water%20Resources/files/publications/Final Draft C
atawba River Basin Plan 2007.pdf.This document does not contain any
specific discharge recommendations for Irwin Creek.
➢ Impaired waters and TMDLs. Certain waterbodies listed as impaired on the 303(d) list
and/or subject to impending TMDLs may have wastewater discharge restrictions.
o ESC reviewed the 303(d) lists for calendar years 2020(final) and 2022 (draft)
found through the NCDEQ website (https://deq.nc.gov/about/divisions/water-
resources/water-planning/modeling-assessment/water-quality-data-
assessment/integrated-report-files). Both the 2020 final listing and the 2022 draft
listing indicate that Irwin Creek from its source to Sugar Creek as impaired
because of issues with Fair, Poor or Severe Bioclassification in its Fish Community.
An excerpt of this document is included as Appendix E. ESC contacted Ms. Pamela
Behm of the NCDEQ, Division of Water Quality, Modelling and Assessment
Branch by email on March 23, 2022 to make an inquiry regarding TMDLs and how
3

they may affect the proposed discharge. Ms. Behm forwarded an email on March
24, 2022 in which she indicated there are no impending TMDLs for Irwin Creek.
Ms. Behm further indicated that the NPDES Permit group will want to ensure the
discharge does not lead to future impairment which is dependent upon
constituents in the treated wastewater. Appendix F includes a copy of the
referenced email.
➢ Presence of Endangered Species. If endangered species are present in the proposed
discharge location,there may be wastewater discharge restrictions.
o ESC contacted Ms.Olivia Munzer of the North Carolina Wildlife Resource Commission
by email on March 23,2021. On April 18,2021, Mr. Munzer responded by email. she
indicated that there are no current records of state or federally listed rare,
threatened, or endangered species in the creek. Appendix F includes copies of email
correspondence with these individuals.
STEP 2-PROVIDE REASONABLE PROJECTIONS FOR POPULATION AND FLOW
➢ Information provided by United States Census Bureau indicates the estimated population
of Mecklenburg County was 1,115,485 in April 2020
(https://www.census.gov/quickfacts/fact/table/mecklenburgcountynorthcarolina/PST045
219). According to information from the North Carolina Office of State
Budget and Management found on the internet at https://www.osbm.nc.gov/facts-
figures/population-demographics/state-demographer/countystate-popujation-
projections the population of Mecklenburg is projected to increase to 1,737,661 by July
2050.
➢ The expected population increase will not increase the anticipated flow rate because the
flow rate is not dependent upon the size of the population.
STEP 3-EVALUATE TECHNOLOGICALLY FEASIBLE ALTERNATIVES
Connection to an existing wastewater treatment plant(public or private)
o The City of Charlotte prohibits the discharge of groundwater to its POTW under
Chapter 23, Section 79 of its Code of Ordinances. A copy of an excerpt from this
section is attached as Appendix G.
o No private wastewater treatment plants are located near the subject site so
connection to a private wastewater treatment plant is not practical.
Land application alternatives, such as individual/community onsite subsurface systems,
drip irrigation,spray irrigation and/or high-rate infiltration galleries.
o Land application is not feasible land available constraints in this urban area of
Charlotte. The EAA guidelines include the following verbiage: ". . . it would not be a
feasible alternative in downtown Charlotte, where there is no land available for
wastewater application."
➢ Wastewater reuse
o It is not practical to reuse the extracted groundwater on this project because the
Brownfields Agreement for this property is expected to prohibit the reuse of
4

extracted groundwater.
Surface water discharge through the NPDES program
o ECS believes discharge to surface water through the NPDES program is the most viable
option for the proposed discharge given the nature of the project,prohibitions to other
discharge options, and financial considerations. ECS is aware of several similar
dewatering projects in the area which NCDEQ approved for NPDES discharges in recent
years. These include the construction dewatering projects: Charlotte Area Transit
System Construction project (Permit No. NC008371), the Myrtle/Morehead Storm
Drainage Improvement project (Permit Nos. NC0089443 and NC0089729),
Dimensional Place Construction project (Permit No. NC0089656), Carolina Theatre
(Permit No. NC0089842), and TGACSE Central Square (Permit No. NC008958).
Permanent dewatering projects include: Carillon Building Dewatering System (Permit
No. NC0085731), Gateway Village (Permit No NC0086517), Wells Fargo Tryon Street
(Permit No NC0088226), BB&T Ballpark(Permit No NC0089273).
➢ Combinations of the aforementioned alternatives
o As discussed previously, connection to an existing wastewater facility, land
application (surface and subsurface), and water reuse are not feasible alternatives.
Therefore, a combination of the aforementioned alternatives is not a feasible
alternative.
STEP 4-EVALUATE ECONOMIC FEASIBILITY OF ALTERNATIVES
According to guidelines for the Engineering Alternatives Analysis, a 20-year Present Value of
Costs Analysis (PVCA) should be performed to provide valid cost comparisons among all
technologically feasible wastewater alternatives identified in Step 3. As indicated in Step 3, ECS
believes discharge to surface water through the NPDES program is the single viable option for
the proposed discharge given the nature of the project, prohibitions to other discharge options,
and financial considerations. Therefore, therefore since there are no options to compare,this
step is not applicable.
2.0 OTHER CONSIDERATIONS
According to guidelines for the Engineering Alternatives Analysis, the Environmental
Management Commission may not act on an application for a new non- municipal domestic
wastewater discharge facility until it has received a written statement from each city and county
government having jurisdiction over any part of the lands on which the proposed facility and
its appurtenances are to be located. The guidelines indicate that the applicant must submit
requests for this information by certified mail, return-receipt-requested.The written statement
shall document whether the city or county has a zoning or subdivision ordinance in effect and (if
such an ordinance is in effect)whether the proposed facility is consistent with the ordinance. The
guidelines indicate that if the applicant does not receive a response from one or both of these
local government entities within 15 days of receiving the request, the applicant may submit an
application for a new non-municipal domestic wastewater discharge facility provided it can
document that these entities received the requests and were allowed at least 15 days to respond.
5

ECS has not received responses from either of the two local government entities at this time.Appendix H includes
copies the request letters and certified mail receipts.These documents demonstrate that ESC provided proper
notification to these government entities and responses were not not received within the specified time.
6

3.0 REMARKS
The activities and evaluative approaches used in this assessment are consistent with those normally
employed in environmental assessment projects of this type. Our evaluation of site conditions has
been based on our understanding of the site project information and the data obtained during our
field activities.

Subject: USGS response to DWR USGS Low Flows request#2022-183 (dated 2022/03/25)for
Irwin Creek Mecklenburg County...RE: [EXTERNAL] Low-flow request approval
Ms. Burdette,
In response to your inquiry about the low-flow characteristics for a location on Irwin Creek adjacent to the on-ramp
from West Morehead Street onto 1-77 North in downtown Charlotte in Mecklenburg County,the following information
is provided:
FOR THE RECORD: This point of interest on Irwin Creek is located near two other points of interest on unnamed
tributaries to Irwin Creek for which estimated low-flow characteristics were recently provided in response to separate
low-flow requests (#2021-176, dated 02/24/2022, #2021-177, dated 03/04/2022). The group of index sites used to
estimate the low-flow characteristics for these two previous points of interest is similar to that used for the low-flow
estimates provided below for the current point of interest. However, please see the notes below concerning the
addition of other nearby index sites as well as the removal of two index sites.
A check of the low-flow files here at the USGS South Atlantic Water Science Center(Raleigh office) does not indicate a
previous low-flow determination for the point of interest, identified by the lat/long coordinates (35.22969, -80.85931)
provided via separate email dated 03/25/2022 from Mr. Klaus Albertin (NCDEQ)following your request submission via
the DWR USGS Low Flow portal.
No USGS discharge records are known to exist for this point of interest.
A basin delineation completed using the online USGS StreamStats application for North Carolina
(https://streamstats.usgs.gov/ssn indicates the drainage area for the point of interest(StreamStats adjusted
coordinates 35.22969, -80.85931 NAD83) is 12.2 sqmi,which confirms the drainage area submitted as part of the
request information.
For the record: Please be aware a degree of uncertainty exists in the low-flow estimates provided below because of the
high percentage of impervious area arising from urbanization in the basin upstream from the point of interest, including
the possibility of low flows being affected by diversion(s)to or from the stream upstream from the point of
interest. While no formal USGS study has been conducted in North Carolina to examine the effects of development
and(or) urbanization on low-flow characteristics, the general thought within the hydrologic community is that
development has the potential to reduce base flow characteristics. Base flow is the portion of the streamflow sustained
by discharge from the adjacent surficial aquifers into the streams and is governed by the amount of runoff that
infiltrates into the ground for later discharge to streams. As noted below, there is a wide range in the low-flow yields
based on the nearby USGS sites used as index sites.
For streams in Mecklenburg County, low-flow characteristics published by the USGS are provided in the following
reports:
1

(1)The first is a statewide report completed in the early 1990's. It is USGS Water-Supply Paper 2403, "Low-flow
characteristics of streams in North Carolina" (Giese and Mason, 1993). An online version of the report is available at
https://pubs.usgs.gov/wsp/2403/report.pdf. The report provides the low-flow characteristics (based on data through
1988)via regional relations and at-site values for sites with drainage basins between 1 and 400 sqmi and not considered
or known to be affected by regulation and/or diversions.
(2)The second is a statewide report published in March 2015. It is USGS Scientific Investigations Report 2015-5001,
"Low-flow characteristics and flow-duration statistics for selected USGS continuous-record streamgaging stations in
North Carolina through 2012" (Weaver, 2015). The report is available online at
https://pubs.usgs.gov/sir/2015/5001/. The report provides updated low-flow characteristics and flow-duration statistics
for 266 active(as of 2012 water year) and discontinued streamgages across the state where a minimum of 10 climatic
years discharge records were available for flow analyses.
Low-flow characteristics estimated for point of interest:
Inspection of the above-referenced reports indicates the presence of twelve (12) continuous-record streamgages (12) in
the general vicinity of the point of interest where low-flow characteristics were published. Among these 12 index sites,
the low-flow discharge yields for the indicated flow statistics are as follows:
Annual 7Q10 low-flow yields==>from 0 to 0.083 cfsm (average about 0.021 cfsm, median about 0.015 cfsm) (zero flow
at 3 of 12 index sites)
Annual 30Q2 low-flow yields==>from 0.082 to 0.21 cfsm (average about 0.13 cfsm, median about 0.12 cfsm)
Winter 7Q10 low-flow yields==>from 0.016 to 0.13 cfsm (average about 0.064 cfsm, median about 0.062 cfsm)
Annual 7Q2 low-flow yields==>from 0.012 to 0.14 cfsm (average about 0.058 cfsm, median about 0.055 cfsm)
Average annual discharge yields ==>from 0.9 to 1.2 cfsm (both average and median about 1.1 cfsm)
Application of the above range in yields to the drainage area (12.2 sqmi)for the point of interest results in the following
estimated low-flow discharges:
Annual 7Q10 low-flow discharges ==>from 0 to 1 cfs (average about 0.26 cfs, median about 0.18 cfs) 4 rounded to 0.2
cfs
Annual 30Q2 low-flow discharges ==>from 1 to 2.6 cfs (average about 1.6 cfs, median about 1.5 cfs)
Winter 7010 low-flow discharges ==>from 0.2 to 1.6 cfs (average about 0.78 cfs, median about 0.76 cfs)
Annual 7Q2 low-flow discharges==>from 0.15 to 1.7 cfs (average about 0.71 cfs, median about 0.67 cfs)
Average annual discharge discharges ==>from 11 to 14.6 cfs (both average and median about 13.4 cfs)
Please note there is a wide range in the low-flow yields for each of the statistics. The range in yields is considered
reflective of the unknown effects that development and(or) urbanization may have on low flows in streams, resulting in
a higher degree of uncertainty or lack of confidence in the estimates.
For the record: With exception of the annual 7Q10 discharge, comparison of the estimated low-flow discharges for the
point of interest are considered reasonable relative to the published low-flow discharges for the upstream continuous-
record streamgage at USGS Sta. 02146211 Irwin Creek at Statesville Avenue at Charlotte (above-referenced report#2,
Table 3, page 25). As noted above,the group of index sites used to estimate the low-flow characteristics for two
previous points of interest are similar to those used for the low-flow estimates provided above for the current point of
interest. During review of the low-flow yields for this response,the yields for 4 additional index sites were added
(02124140,0214295600, 02146562, and 02146600). Additionally,the low-flow yields at two of the streamgages
(02146300 and 02146409)were removed from the group after further inspection of the values suggest these yields may
be affected by major upstream diversions(?).

Please note:
(1)The estimated flows are provided in units of cubic feet per second (cfs).
(2)The low-flow yields provided above are rounded to 2 significant figures. Estimated low-flow discharges less than 1
cfs are rounded to 2 significant figures. If between 1 and 100 cfs,then rounded to 1 decimal place; if greater than 100,
then rounded to the nearest whole number(zero decimal places).
(3)The information provided in this message is based on a preliminary assessment and considered provisional, subject
to revision pending collection of future data and further analyses.
These provisional streamflow statistics are provided via the DWR USGS Low Flows cooperative agreement between

Subject: RE: [External] Engineering Alternatives Evaluation for NPDES Permitting
Ms. Burdette,
We have no current records of state or federally listed rare,threatened,or endangered species in the creek; however,
we always recommend contacting the USFWS regarding federally listed species. In general,the lack of records from the
site does not imply or confirm the absence of federal or state rare,threatened, or endangered species. An on-site
survey is the only means to determine if the proposed project may impact federal or state rare,threatened, or
endangered species.
Overall,we have no major concerns since the discharged groundwater will first be treated using a granular activated
carbon. However,for the metals,we recommend using another removal process such as reverse osmosis or ion
exchange.
Also, ensure the water discharges from the site should be proportional to the size of the receiving stream so the
hydrology of the stream is not altered, and all discharges should comply with NPDES permit requirements,especially
when water levels are low. In particular,turbidity of the discharge should be maintained at or below the permit
requirement.
Please let me know
o if you have further questions.

Ms. Munzer,
ESC Southeast, LLP is working on a National Pollutant Discharge Elimination System (NPDES) permit application for a
construction dewatering project in an urbanized area of Charlotte. The NPDES permit branch of the North Carolina
Department of Environmental Quality(NCDEQ) has indicated that we should check with your agency to determine if your
rules would impose restrictions for the proposed discharge. Hence that is why we are contacting you.
The NPDES permitting process requires that an Engineering Alternatives Evaluation (EAA) be performed. NCDEQ guidance
indicates that the proponent must first determine if the discharge may be allowed.The guidance indicates that

the proponent should determine if there are any limitations as a result of the presence of endangered species.
Specifically the guidance states:
Presence of Endangered Species. If endangered species are present in the proposed discharge location,there may be
wastewater discharge restrictions. Endangered species information may be included in the Basinwide Water Quality Plan,
or you may contact the U.S.Fish and Wildlife Service (919-856-4520), N.C. Wildlife Resources Commission (919-733-3633),
or the N.C. Natural Heritage Program (919-733-7701).
Analysis of groundwater samples collected from monitoring wells constructed at the site in 2021 indicated low levels of
VOCS detected in the samples.
We anticipate treating extracted ground water to low(Non—detect to single digit part per billion levels) using granular
activated carbon. Discharge at the subject site will be to the City stormwater system.The stormwater system will
discharge to Irwin Creek, within the Catawba River basin.The discharge point is located at 35.229 and -80.859. We
anticipate flow rates of 50 gpm or less.
We would like to determine if there are endangered species in the basin downstream of the discharge point which may
cause wastewater discharge restrictions with respect to the proposed discharge.
Can you or another member of your staff help me on this matter, please?

Ms. Behm,
ECS Southeast, LLP (ECS) has been requested by a client to prepare NPDES permit application for foundation dewatering
at a property located at 1102, 1106, and 1018 South Tryon Street, Charlotte, NC. Groundwater in the area has been
affected by volatile organic compounds (SVOCs/VOCs). If approved,treated groundwater from the dewatering operation
will be discharged to Irwin Creek in Charlotte.Treatment is proposed to consist of settling,filtration of particulates, and
removal of SVOCs/VOCs by granular activated carbon.A guidance document provided by the NPDES permitting group
indicates we should investigate Impaired waters and TMDLs to determine if such a discharge would be prohibited before
making the effort to prepare the application.An excerpt from that guidance is below:
• Impaired waters and TMDLs. Certain waterbodies listed as impaired on the 303(d) list and/or subject to
impending TMDLs may have wastewater discharge restrictions.The list of 303(d) impaired waters is located on
the DWR website, or you may contact the DWR Modeling and Assessment Branch
(http://portal.ncdenr.org/web/wq/ps/mtu).
Please let us know if there are any impending TMDLs which may have wastewater discharge restrictions with respect to
the proposed discharge.

Sec.23-79.- Prohibited discharge standards.
(a) Genera/prohibitions. No user shall discharge or cause to be discharged into the POTW any
pollutant or wastewater which causes interference or pass through.The general prohibitions
in this section apply to all users of the POTW.
(b) Specific prohibitions. No user shall discharge or cause to be discharged into the POTW the
following:
(1) Any pollutants which, either alone or by interaction with other pollutants, create a fire or
explosive hazard in the POTW, including, but not limited to,waste streams with a closed
cup flashpoint of less than 140 degrees Fahrenheit(60 degrees Celsius)using the test
methods specified in 40 CFR 261.21.
(2) Solid or viscous pollutants,fats, oils, or greases from animal or vegetable origin in
amounts which may cause obstruction to the flow or other interference in the POTW.
(3) Any wastewater having a pH less than 6.0 or greater than 12.0, or having any other
corrosive property capable of causing damage or hazard to the POTW.
(4) Pollutants, including oxygen demanding pollutants(cBOD 5, BOD 5, COD, etc.), released in
a discharge at a flow volume, flow rate and/or pollutant concentration which, either singly
or by interaction with other pollutants, will cause interference with the POTW.
(5) Any noxious or malodorous liquids,gases or solids which, either singly or by interaction
with other pollutants, are sufficient to create a public nuisance or hazard to life or are
sufficient to prevent entry into the sewers for maintenance and repair.
(6) Any pollutant released in a discharge at a flow volume, flow rate and/or pollutant
concentration which, either singly or by interaction with other pollutants, may cause the
POTWs effluent or any product of the POTW, such as residues, sludges or scums,to be
unsuitable for reclamation and recycling or to interfere with the reclamation process. In
no case shall a substance discharged to a POTW cause the POTW to be in noncompliance
with applicable local, state or federal sludge use or disposal guidelines.
(7) Any pollutant released in a discharge at a flow volume, flow rate and/or pollutant
concentration,which will, either singly or by interaction with other pollutants, cause the
POTW to violate any of its NPDES and/or state disposal system permits or the receiving
water quality standards.
(8) Any discharge having a temperature greater than 150 degrees Fahrenheit(66 degrees
Celsius)or which will inhibit biological activity in the POTW treatment plant resulting in
interference but, in no case, a discharge which causes the temperature at the introduction
into the POTW treatment plant to exceed 40 degrees Celsius(104 degrees Fahrenheit).
(9) Any pollutant which results in the presence of toxic gases,vapors, or fumes within the
POTW in a quantity that may cause acute or chronic worker health and safety problems.
(10) Any wastewater containing any radioactive wastes or isotopes except as specifically
approved by CMUD in compliance with applicable state or federal regulations.

4/6/22,9:01 AM Charlotte,NC Code of Ordinances
(11) Any discharge at a flow rate which will cause interference with the POTW.
(12) Any pump and haul waste, except at discharge points designated by CMUD in accordance
with section 23-81 of this article.
(13) Any waste stream which imparts color and passes through the POTW treatment plant,
including, but not limited to, dye wastes and vegetable tanning solutions,which
consequently imparts sufficient color to the POTW treatment plant's effluent,thereby
violating any state or federal regulations pertaining to the effluent from the plant or the
receiving water.
(14) Stormwater, surface water,groundwater, artisan well water, roof runoff, subsurface
drainage, and swimming pool drainage, unless specifically authorized by CMUD.
(15) Any removed substances to include, but not be limited to, sludges, screening, or other
residues from the pretreatment of wastewater.
(16) Petroleum oil, nonbiodegradable cutting oil, synthetic oil, or products of mineral oil origin,
in amounts that will cause interference or pass through.
(17) Any indirect discharge which, alone or in combination with other wastewater, causes the
treatment plant effluent to violate state water quality standards for toxic substances as
described in 15 A NCAC 2B .0200.
(18) Any pollutant that will emulsify grease or oil or cause grease or oil to solidify or become
more viscous.
(19) At no time shall two successive readings on an explosion hazard meter, at the point of
discharge into the POTW, or at any point in the POTW, be neither more than five percent
nor any single reading over ten percent of the lower explosive limit(LEL).
(20) Any material that would be identified as hazardous waste according to 40 CFR Part 261 if
not disposed of in a sewer, except as may be specifically authorized by CMUDD.
(c) Processing and storage. Pollutants, substances or wastewaters prohibited by this section shall
not be processed or stored in such a manner that they could be discharged to the POTW.
When CMUD determines that a user(s) is contributing to the POTW, any of the above enumerated
substances in such amounts which may cause or contribute to interference of POTW operation or pass
through, CMUD shall:
(1) Advise the user(s) of the potential impact of the contribution on the POTW in accordance
with section 23-95; and
(2) Take appropriate actions in accordance with article Ill, and the sections contained therein,
for such user to protect the POTW from interference or pass through.
(d) National categorical pretreatment standards. Users subject to categorical pretreatment
standards are required to comply with applicable standards as set out in 40 CFR Chapter 1,
Subchapter N, Parts 405-471:
(1) Where a categorical pretreatment standard is expressed only in terms of either the mass

4/6/22,9:01 AM Charlotte,NC Code of Ordinances
or the concentration of a pollutant in wastewater, CMUD may impose equivalent
concentration or mass limits in accordance with 40 CFR 403.6(c).
(2) When wastewater subject to a categorical pretreatment standard is mixed with
wastewater not regulated by the same standard, CMUD shall impose an alternate limit
using the combined wastestream formula in 40 CFR 403.6(e).
(3) A user may obtain a variance from a categorical pretreatment standard if the user can
prove, pursuant to the procedural and substantive provisions in 40 CFR 403.13,that
factors relating to its discharge are fundamentally different from the pretreatment
standard.
(4) A user may obtain a net gross adjustment to a categorical standard in accordance with 40
CFR 403.15.
