Re: NPDES permit application (Short Form C -GW) - request to discharge into the
City of Charlotte municipal stormwater system from the Myrtle/Morehead Storm
Diainage Improvement Project in Charlotte, NC
Division of Water Resources:
Regarding the City of Charlotte's request in their NPDES permit application C -GW to
discharge treated water from a remediation system at the above -referenced location into
Charlotte's stormwater system, Charlotte Mecklenburg Storm Water Sei vices (CMSWS)
approves the discharge.
CMSWS would like to make the permittee and NC DEQ aware of the following
considerations and information:
CMSWS does not guarantee adequate capacity is available to permitted
dischargers to keep any property or street flee of water or harm as a result of this
discharge.
CMSWS takes no responsibility for backflows fi•om the public drainage system
into the permitted discharger's system.
CMSWS is aware of trichloroethylene (TCE) and perchloroethylene (PCE) levels
above Class C surface water human health standards in Little Sugar Creek (the
proposed receiving water) between E. 36th St. and N. Brevard St. in Charlotte,
NC. The contaminated area is located approximately 3.6 miles upstream from
where the remediation system discharge receiving tributary would enter Little
Sugar Creek. The source of surface water contamination is soil and groundwater
contamination at a vacant industrial property along Cullman Avenue. Kathleen
Lawson with the NC DEQ Hazardous Waste Section is managing the required
remediation in cooperation with the responsible party if you would like more
specific information.

1.0 SITE INFORMATION
1.1 Site Description
The remaining parts of the Myrtle/Morehead project for the City of Charlotte, Stormwater
Services, will include drainage improvements to the stormwater drain system to relieve flooding
in upper reaches of a tributary of Little Sugar Creek. The area that experiences flooding extends
along South Boulevard between Rensselaer Avenue and Templeton Avenue and extends to areas
east and southeast of that interval of South Boulevard. These areas encompass the proposed
storm drainage improvement construction area, generally between South Boulevard and Euclid
Avenue, and between Rensselaer Avenue and Templeton Avenue. Figure I indicates the project
location on part of a United States Geological Survey, topographic quadrangle map.
The project will entail trenching to depths below the expected water table elevation in
unconsolidated overburden soils beneath the water table along the proposed stormwater drain
alignments. Construction could also encounter bedrock and its included fractures that contain
groundwater. Dewatering will therefore likely be required during project construction. The
groundwater is proposed to be collected, treated, and discharged to stormwater drains which will
convey the flow to a Class C surface water.
Research of environmental conditions in the project vicinity and monitoring of groundwater
monitoring wells were performed by Hart and Hickman. McCorkle's Cleaners, a former
drycleaner, operated at 1437 South Boulevard. According to a Groundwater Monitoring Report
by Hart and Hickman in April 2016, chlorinated solvent impact was identified in the site
monitoring well network. Figure 2 depicts the extent of the chlorinated solvent impact
superimposed on the storm drain system and easements in the affected area. According to the
analytical data presented in the Groundwater Monitoring Report, potential exists for groundwater
to be impacted by drycleaning solvents in this area. Other downstream/downdrain locations with
anticipated improvements are through residential areas with low potential for groundwater
impact.

ATC Project No 199WOO1701 October 16, 2017
The NPDES Permit Application Form is provided as Appendix A, and the other attachments to
include a groundwater analytical table, a USGS topographic map, and a site map with
contaminant plume and discharge locations, and a proposed groundwater treatment system, as
requested by the permit application form.
1.2 Site Background
The former McCorkle's cleaners operation operated at 1437 South Boulevard, Charlotte, North
Carolina. The former drycleaner is monitored and regulated as part of the Dry -Cleaning Solvent
Cleanup Act (DSCA) Program. Figure 2 depicts the site on an aerial photograph, with pertinent
site features. Hart and Hickman conducted a groundwater monitoring event in March 2016.
Chlorinated solvent impact above North Carolina Groundwater and Surface Water Standards was
identified in the monitoring well network for multiple chlorinated solvent constituents. Potential
dewatering associated with the Myrtle/Morehead Storm Drainage Improvement project could
generate groundwater that includes tetrachloroethylene (PCE), trichloroethylene (TCE), and
vinyl chloride (VC) above North Carolina Class C Surface Water Quality Standards (North
Carolina Administrative Code, Title 15A, Subchapter 213; 2B Standards). A summary of
groundwater analytical data and other impact information is provided in the Hart and Hickman
Groundwater Monitoring Report in Appendix B.
Figure 2 in the attached appendix indicates the alignment of the drain construction, and
subsurface impact, principally by chlorinated solvents, which the drain construction is likely to
encounter. Table 1 in the attached appendix provides a summary of maximum concentrations for
groundwater impact based on testing along the proposed construction alignment. Approximately
400 linear feet (STA 3+00 to 8+00) of 48 -inch RCP will be installed with trench depths up to 20
feet deep with anticipated groundwater depth as shallow as 5 feet deep. The project duration
should not exceed six months.
The currently available groundwater concentrations were derived from analysis of volatile
organic compounds via EPA Method 8260B, which is a standard environmental analysis of
environmental media specified in the EPA SW -846 manual. Testing of groundwater in impacted

ATC Project No 199WO01701 October 16, 2017
areas will be conducted prior to NPDES discharge via EPA Method 8260 to confirm conditions
found by the prior analyses. Testing of NPDES-permitted treatment system conditions will also
be conducted by EPA Method 8260 during discharge treatment.
1.3 Dewatering Conditions and Flow Projections
The source of groundwater from dewatering will likely be primary porosity from residual soils
below the water table. Although rock tunneling is not expected in the project area potential exists
for limited sections of the storm drain system to encounter bedrock and for dewatering to occur
from bedrock fractures. The volume of flow associated with dewatering will likely be variable
based on the materials encountered and other factors; however, the estimated flow volumes are
based on historic flow volumes documented during dewatering along Baxter Street on the
northeastern end of the project, at prior Outfall 3, and flow at the tunnel section, which included
bedrock near the intersection of Morehead Street with Oriole Street, at prior Outfall 1. This
dewatering, treatment and discharge occurred under NPDES Permit NC0089443.
The prior dewatering and treatment was conducted during the period of fall 2014 through the
winter of 2016. Flow was variable based on construction activities and the aquifer materials that
were encountered. The observed flow rates ranged from lows of approximately 0.56 to 1.0
gallons per minute (gpm) up to maximum flows approaching 14 gpm. The lowest flows were
recorded in areas that involved trenching through soil overburden aquifer conditions, and the
highest flows resulted during tunneling through bedrock.
Based on experience with the prior trenching and tunneling at other area's of the project, as well
as bedrock hydraulic testing in the Piedmont Physiographic Province, a rough range of likely
flow volumes for the dewatering if groundwater is encountered could be approximately 1.0 to 50
gpm. ATC estimates an amount for this proposed permit that is less than NPDES Permit No.
0089443, based on the depth and lateral exposure of excavation that are expected to be less than
the downstream parts of the construction. The actual amount of dewatering volume during
construction will depend upon the length of trenching interval that is exposed to aquifer and
whether the excavation occurs within residual soils or in water bearing fractures.

ATC Project No. 199WOO1701 October 16, 2017
The area of stormwater improvements proposed for the area approximately 400 to 800 feet to the
east of the intersection of South Boulevard and Rensselaer Avenue encompasses groundwater
impact by chlorinated solvents from the former McCorkle's Cleaners that exceed surface water
standards.
The anticipated dewatering fluids will contain PCE, TCE, and VC impact exceeding 2B
Standards for Class C surface water in the area of the receiving waters. The standard for fish
consumption in Class C waters is 3.3 ug/L for PCE, 30 ug/L for TCE, and 2.4 ug/L for VC.
Collection of groundwater containing impact concentrations of up to 113 ug/L of PCE, 50.7 ug/L
of TCE and approximately 15.2 ug/L of VC could be expected given the most recent
groundwater conditions found during an April 2017 monitoring event of the apparent releases at
McCorkle's Cleaners. Table I contains the maximum concentrations from the April 2017
monitoring event, and Appendix B contains the June 2017 Groundwater Monitoring Report for
the April 2017 sampling data. For the purposes of treatment design, ATC has assumed a flow of
up to 50 gpm, with the three regulated chlorinated solvents' concentrations indicated above, so
that treatment would result in discharge concentrations that are less than the Class C surface
water standards.

2.0 ENGINEERING ALTERNATIVES ANALYSIS
The North Carolina Division of Water Quality Engineering Alternatives Analysis (EAA)
Guidance Document, dated June 23, 2005, requires an evaluation of wastewater disposal
alternatives in addition to direct discharge. The subject discharge will be from a groundwater
remediation system and the following wastewater disposal alternatives are therefore being
evaluated:
• Connection to an existing wastewater treatment system
• Land application
• Infiltration galleries
• In-situ groundwater remediation wells
• Closed-loop groundwater remediation wells
2.1 Connection to an Existing Wastewater Treatment System
ATC contacted the Charlotte Water to determine if groundwater from the onsite treatment
system could be discharged to the Charlotte Water's Publicly Owned Treatment Works (POTW).
Charlotte Water did not provide permission to discharge pre-treated groundwater to the sewer
system. Thus, POTW discharge for the treated water will not be an acceptable alternative for
discharge of treated dewatering fluids.
2.2 Land Application
Land application of groundwater through drip irrigation or spray irrigation is not a feasible
alternative for disposal of dewatering fluids at the project site. The project is located in an urban
area of Charlotte, and sufficient permeable land is not available in the vicinity for groundwater
application. The land area requirements also entail setbacks of the land application areas from
property boundaries. Additionally, the drainage construction project will be conducted in
municipal roadways, and unpaved private properties would therefore need to be acquired for land
application purposes. According to sales records obtained from Charlotte -Mecklenburg
POLARIS (Property Ownership and Land Records Information System), private properties in the
project vicinity would cost approximately $500,000 to $2,000,000. Groundwater treatment,
5 ATC Associates of North Carolina, P C

EAA & NPDES Permit Application Myrtle/Morehead Storm Drainage Improvement
ATC Project No. 199WOO1701 October 16, 2017
which would be required prior to irrigation, would add to the expense of this alternative. Based
on excessive expenses needed for property purchases, as well as lack of available permeable
area, land application is not a feasible alternative.
2.3 Infiltration Galleries
An infiltration gallery is a horizontal drain constructed of perforated piping and surrounded by
permeable material, such as sand or gravel, which distributes treated water for infiltration to
subsurface soils. An infiltration gallery should be able to store and transmit water to the
subsurface at the same or greater rate that water is being added to prevent flooding. Assuming
the maximum potential discharge rate of 50 gpm, the surficial silt and clay of the Piedmont
would not transmit dewatering fluids at a sufficient rate to prevent flooding. ATC personnel have
extensive experience with past efforts through non -discharge permitting where infiltration, in
Piedmont soils with much lower flow rates were unsuccessful, even with expansion of
infiltration galleries beyond original designs. The galleries would also require extensive land
area for construction, which is not available at the subject site. In addition, because the proposed
project area spans over 1000 feet, a stationary discharge location would not be feasible and
multiple galleries would be necessary. The use of infiltration galleries for discharge of
dewatering fluids is infeasible for the project.
2.4 In -Situ Groundwater Remediation Wells
At least two separate classes of technologies could be interpreted to meet the definition of in-situ
groundwater remediation. In one sense, in-situ groundwater remediation would be conducted by
injection of materials designed to reduce contaminant concentrations in groundwater, so that
water collected during construction dewatering could be directly discharged, without additional
treatment, to surface waters. Such in-situ remediation usually relies upon trenches, galleries, or
injection wells to infiltrate fluids that remediate dissolved contaminants and contaminants that
are sorbed to the soil and aquifer matrix. Such materials either enhance natural biological
processes of aerobic or anaerobic metabolism; act chemically upon the contaminants by
oxidation or reduction; or provide a material, such as activated carbon, to sorb the contaminants.
Combinations of the technologies are also often used.
6 ATC Associates of North Carolina, P C

EAA & NPDES Permit Application Myrtle/Morehead Storm Drainage Improvement
ATCProiectNo 199WOO1701 October 16. 2017
In-situ groundwater remediation can be effective at reduction of impact to achieve groundwater
regulatory goals; however, full remediation in the limited time before inception of the storm
drain improvement project, especially to concentrations below surface water standards, would be
unlikely. Property access across a much larger footprint than the project currently affects would
also be necessary for effective remediation of materials that might migrate to the dewatering
locations. Reactive barrier walls installed by trenching could be attempted. Again, the project
footprint would be excessively expanded, and potential for impacted groundwater to migrate
beneath the reactive barrier trench would be enhanced due to the dewatering. If wells were used
an underground injection control (UIQ permit would also be required. Full remedial costs to
render the impacted groundwater suitable for discharge would also be prohibitively expensive, if
such a method were even technologically feasible, which is not certain.
Another potential interpretation for in-situ groundwater remediation entails that dewatering
fluids be collected, treated, and re -injected to specifically -installed, subsurface injection wells for
management of the fluid. This process would require sufficient wells for the Piedmont bedrock
aquifer to accept the injection of the dewatering fluid. Approval of the fluid injection would also
require a UIC permit. Installation of piping to carry the fluids to the injection well locations
would be needed, or contaminated water would need to be transported to a separate area for
injection. An extended period of time of likely many years for chlorinated remediation, using
what is essentially a pump -and -treat technology, would also be required and would constitute an
unacceptable time period given the project schedule. As with other alternatives the pump and
treat method with re-injection would be unnecessarily expensive. In-situ groundwater
remediation is judged to be an unacceptable alternative for the project.
2.5 Closed -Loop Groundwater Remediation Wells
A closed-loop groundwater remediation system, typically using recirculation well technology,
collects groundwater from one aquifer interval, treats the groundwater within the well, and
injects the treated water into another aquifer interval. The technology can be set up to operate in
several ways. The water can be collected from a shallow zone, treated, and then inject to a deeper
zone, or the opposite arrangement can be made. Hybrid setups of multiple collection and
7 ATC Associates of North Carolina, P C

EAA & NPDES Permit Application Myrtle/Morehead Storm Drainage Improvement
ATC Project No. 199WOO1701 October 16, 2017
injection zones may also be possible. The hydraulic modeling and design of an inject well system
typically strives to achieve a re -circulation cell in the local groundwater regime, so that impacted
water migrating to the recirculation cell is captured and treated, with the net effect being that the
recirculation cell prevents impacted water from passing the recirculation cell.
As with other remedial options that require groundwater treatment, additional area and property
access would be required for recirculation; pilot testing would be needed to assure that a
sufficient number of wells were placed along the construction alignment; and certainty of
successful cleanup could not be assured, especially because the construction alignment is
through existing groundwater impact. The schedule to provide groundwater cleanup along the
alignment would also be an extended period. The action of dewatering adjacent to the
recirculation wells would also have uncertain consequences and could adversely affect the
technology's ability to assure clean dewatering discharge. Because of the cost of $100,000 or
more per recirculation well, the technology would also be likely to have very high costs. Closed-
loop groundwater remediation wells would be an unacceptable alternative for achieving
groundwater cleanup that would result in clean dewatering fluids collection prior to the project
start.

ATC Project No 199WO01701 October 16, 2017
3.0 PROPOSED GROUNDWATER TREATMENT SYSTEM
Appendix A contains the NPDES Permit Application, Short Form C—GW, with supporting
documentation. The proposed groundwater treatment system consists of an air stripper,
Carbonair STAT 80 or equivalent, with four trays and a 350 cubic feet per minute (CFM) blower
with a flow capacity of up to 50 gpm to volatilize the expected chlorinated solvent impact in
groundwater for atmospheric discharge. Groundwater extracted from the trenching project will
be collected into an optional weir/equalization tank to reduce sediment, then into a holding and
settling vessel of approximately 500 to 1,000 gallons each. Flow from the holding tank will be
float switch -controlled and pumped at a maximum rate of 50 gpm through two, parallel filtration
units to remove sediment, and then proceed into the air stripper. The water will then cascade
downward through the ventilated air stripper trays as the air is forced upward through the air
stripper. Once in the holding tank at the base of the air stripper, a set of float switches will
control discharge via a second pump to the NPDES discharge location. Additionally, a second set
of, redundant pumps of 50 gpm maximum capacity will be placed for pumping to the air stripper
from the holding tank and after the air stripper to pump to the discharge. The second, redundant,
set of pumps before and after the stripper will serve as emergency pumps to assure continued
operation in case of filter clogging or other failure of one of the primary pumps. Figure 3 in the
attached appendix is a proposed treatment system schematic.
Two stormwater drains have been proposed for potential discharge and are located in an
easement area near the intersection of Cleveland Avenue and Rensselaer Avenue and in an
easement near the bend of South Caldwell Street. The final discharge point of the two storm
drains is Little Sugar Creek and its tributaries. Figure 2 in the attached appendix shows the
proposed discharge locations on a site plan.
A maximum flow rate of 50 gpm and influent concentration maximums from Table I were used
for treatment system design purposes. Table 2 provides model output for treatment by the
specified air stripper or equivalent. The effluent will be sampled initially upon treatment system
startup and again for the system startup after major changes in dewatering locations during the
project. Once certainty regarding dewatering fluid conditions is obtained for each area of

ATC Project No 199WO01701 October 16, 2017
construction, the need for continued NPDES permitted discharge will be evaluated and
communicated to the NPDES Permitting Unit. For each application, the system effluent will be
sampled once per week during the first month of operation and for each month of treatment
system operation thereafter. The laboratory analytical data using EPA Method 8260 for volatile
organic compounds will be utilized to determine that required treatment is being met. The
operator in responsible charge (ORC) will submit monthly discharge monitoring reports
(DMRs).

4.0 DISCUSSION
Consideration should be given to the overall storm drainage improvement as a rationale for
requesting NPDES permitting as part of the project construction. That is, the goal of the project
is limit flooding during major storm events, which, especially in urban settings, present
significant contributions to adverse surface water quality conditions. The routing of the drain in
its large diameter, downstream segment as proposed will aid the project schedule and limit the
number of flood events affecting headwaters of the drainage during the planning and
construction phases. Please note that the project design includes methods to seal the drain against
impacted groundwater incursion across intervals affected by groundwater impact. Thus, the
proposed NPDES permit will allow construction of a drainage improvement that will ultimately
serve to increase water quality.

Carbonair's STAT Modeler is accurate only when contaminants are completely
dissolved in water in the absence of substances, which may significantly
affect the stripper capabilities of contaminants, such as oil & grease,
surface active and foaming agents, alcohols, ketones, and other potential
Henry's constant altering contaminants. Although the effluent
concentration predictions made by the STAT Modeler are accurate
predictions of field performance, they do not constitute a guarantee that
these concentrations will be met in the field. Please contact your
Carbonair representative for a design review and confirmation.

Quality Assurance/Quality Control Procedures
DSCA ID No.: DC600077
Describe the standard quality assurance/quality control (QA/QC) procedures which are practiced in order to
ensure that the samples are representative of actual conditions and that analytical results are valid
The water level and water quality meters were decontaminated using Alconox detergent and distilled water
after each well was gauged, measured, and/or pumped to avoid cross -contamination New nitrile gloves and
purge/sample tubing (both polyethylene and silicone) were used at each well Samples were collected
directly into laboratory -prepared sample containers, labeled with the site and sample identifications, time,
date, sampler's initials, and analysis method Samples were secured in protective wrap or bags before being
covered with ice and cooled to 4 degrees Celsius in a laboratory -supplied sample cooler A sample chain -of -
custody was completed and placed in the sample cooler The cooler was picked up by a courier for delivery
to TestAmerica Laboratories, Inc in Nashville, Tennessee The laboratory ran standard Type Il QC
measures.
Describe the specific sampling technic ue employed during the collection of all ground water samples.
Standard USEPA-approved low-flow/low-stress purge techniques were employed during the collection of the
groundwater samples Polyethylene tubing was installed to the middle of the well screen, secured at the top
of the well, and connected to a short piece of silicone tubing at the peristaltic pump rotor A second piece of
polyethylene tubing was connected to the outflow side of the silicone tubing Depth -to -water was then
measured with a decontaminated water level probe, and the probe was set at the top of the water column
Groundwater was drawn through the tubing by the peristaltic pump at a rate that prevented drawdown of the
water column in the well (approximately 100-250 mUmm at this site) Field measurements of temperature,
pH, conductivity, dissolved oxygen (DO), and oxidation-reduction potential (ORP) were collected during low
flow purging Readings of each parameter were collected at 5 minute intervals After field readings stabilized,
samples were collected using the EPA -approved "soda -straw method".
Describe the EPA approved methods used to extract and analyze the samples submitted the laboratory.
Reference the maximum holding time for each type of analysis performed
Groundwater samples were analyzed for volatile organic compounds (VOCs) by EPA Method 8260B The
maximum holding time for VOC analysis is 14 days from the sample collection date (when the sample is
preserved in HCL). All samples were preserved with HCL and were analyzed within 14 days of collection
There were no discrepancies noted on the laboratory analytical reports for the analytes detected in the
samples

Conclusions
Instructions Discuss any trends or changes noted in analytical results
Hart & Hickman, PC (H&H) conducted a groundwater sampling event on April 24, 2017, which included gauging water levels
and collecting samples from all site monitoring wells The primary constituents of concern at the site are tetrachloroethene
(PCE) and it's degradation products trichloroethene (TCE), cis-l,2-dichloroethene (cis-1,2-DCE), trans-l,2-dichloroethylene
(trans-1,2-DCE), and vinyl chloride (VC) Other petroleum -related compounds are present in site monitoring wells (see Table
8)
Graphs of concentration versus time are provided in Attachment 6 Based on review of the graphs, PCE and TCE
concentrations in source area shallow monitoring well MW -2S have fluctuated dramatically over time and were not detected
during the April 2017 event Concentrations of cis-1,2-DCE, trans-1,2-DCE, and VC have been more consistent in MW -2S
over time Concentrations of PCE and its degradation products in deeper source area monitoring well MW -21), nearby
downgradient well MW -3, and the remaining upgradient and downgradient wells (except MW -6) appear to be generally stable
or decreasing However, concentrations in MW -6 (located approximately 360 ft downgradient of the source property to the
southeast) appear to be increasing overtime Additional sampling is needed to further evaluate concentration trends a the site
Recommendations
H&H conducted a groundwater sampling event at the McCorkle's Cleaners site on April 24, 2017 to evaluate
current concentrations in the site monitoring wells. The analytical results indicate a potential decreasing
concentration trend for dry-cleaning related constituents in source area monitoring well MW -2S and an
increasing trend in downgradient well MW -6 (located in a residential area). Concentrations in the remaining
site monitoring wells appear to be stable or decreasing. H&H recommends additonal groundwater sampling to
further evaluate groundwater concentration trends at the site

CLASS I SDWA SYSTEM means a Class I deep well facility regulated under the Safe Drinking Water Act (SDWA)
CWA SYSTEM means a centralized wastewater treatment facility discharging under a Clean Water Act (CWA) permit For example, a CWA
facility would treat organic or inorganic aqueous wastes and discharge the treated effluent to the local sewer system. Examples of CWA
treatment systems owned and operated by Clean Harbors include the wastewater treatment operations at Baltimore (including the CES
system), Bristol, Chicago, Cincinnati and Cleveland.
CWA-EQUIVALENT SYSTEM means a "zero discharge system" that engages in "CWA-equivalent" treatment before land disposal Zero -
discharge facilities treat hazardous wastes using "CWA-equivalent" treatment methods, but do not discharge the treatment effluent to a
sewer or water body (e g., spray irrigation land farm). "CWA-equivalent" treatment methods means biological treatment for organics, alkaline
chlorination, or ferrous sulfate precipitation for cyanide, precipitation/ sedimentation for metals, reduction of hexavalent chromium, or other
treatment technology that can be demonstrated to perform equally or greater than these technologies.
HIGH TOC IGNITABLE LIQUIDS SUBCATEGORY means an ignitable liquid hazardous waste (waste code D001) which contains
greater than or equal to 10% total organic carbon (TOC) Pursuant to 40 CFR 268 40, such wastes must be treated using organic recovery
(RORGS) or combustion (CMBST) technology. Examples of RORGS technologies include the CES unit at Clean Harbors of Baltimore
Examples of CMBST technologies include hazardous waste fuel blending and subsequent reuse at a cement kiln, or destruction at a RCRA
incinerator
WASTEWATERS are wastes that contain less than 1% by weight total organic carbon (TOC) and less than 1% by weight total suspended
solids (TSS). [See 40 CFR 268.2(f)]
