1.0 PROJECT DESCRIPTION
Morehead Tryon Land LP (Morehead Tryon or the Applicant) proposes to construct three (3) high-
rise, mixed -use towers with 2- or 3-story underground parking structures advanced below the local
groundwater table; Parcels include Nos. 123-012-02, 123-012-03, 123-012-05, 123-012-06, 123-
012-07 and 123-0140-01 located between S. Trion St / Morehead Square Dr & E. Morehead St / E.
Carson Blvd. The Applicant proposes to discharge at 0.075 GPD (estimated groundwater recovery
at 112 gpm). This is herein designated as the permitted effluent flow rate, not to exceed.
Fact Sheet-- NEW NPDES Permit NC0090123
Morehead Tryon Land LP — Queensbridge Collection
Page 1 of 8

The Applicant proposes to pre -treat groundwater (est. recovery rate 112 gpm) dewatered while
excavating sub -grade concrete parking structures, to include pilons and a proposed slab located 2 ft
below the groundwater surface (est. slab area 153,900 ft2). Treated effluent is approved to discharge to
an existing stormsewer inlet by Charlotte -Mecklenburg Stormwater Services (letter dated June 6,
2022). This stormsewer inlet is designated Outfall 001 located at LAT/LONG = 35°, 13' 11" N / 80°,
51', 04" W. Ultimately, treated effluent reaches surface waters at Little Sugar Creek, LAT/LONG =
35°, 13' 2.4" N / 80°, 50', 42.3" W, as approved under this NPDES permit.
2.0 BACKGROUND
The Applicant's site -assessment identified "limited groundwater impacts" at the site, apparently
the result of petroleum release(s) from former underground storage tanks located adjacent to the
existing Uptown Cabaret, a building in the northern corner of the site.
3.0 RECEIVING -STREAM EVALUATION
Little Sugar Creek and its UTs by association are currently classified C waterbodies located within
the Catawba River Basin. Little Sugar Creek is listed by the Division as impaired [2018 North
Carolina 303 (d) List]. Established total maximum daily loads (TMDLs) include:
• Fecal Coliform
• Turbidity limit [< 50 NTU].
• Dissolved Oxygen [daily average not < 5 mg/ L; instantaneous value
not < 4 mg/L during 7Q10 stream -flow conditions.
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 02B.0206 (d)],
see 4.0 DWR Evaluation of Proposed Discharge.
4.0 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 EPA applications, table
Summary of Analytical results and details provided by Pace Analytical Services, LLC, page 4 of
38]. DWR has added monitoring Weekly for these organic and inorganic analytes (see permit
Section A. (1.)]. Metals require effluent monitoring for Total Hardness to established compliance
with EPA guidelines for metals in dissolved fraction [see below, 9.0].
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
• Base -Neutral Acids (Semi -Volatile Organics), EPA Method 625
• Total PAHs, EPA Method 8270
While site -assessment soil and groundwater analyses provide potential COCs, there are no treated
effluent data to date. Table A. (1) includes a footnote allowing the Permittee to petition to alter
parameters and/or monitoring frequency, as future data may warrant [see permit section A. (1.)].

Page 2 of 8

5.0 ESTABLISHING COMPLIANCE & PERMIT LIMITS
The Applicant proposes to discharge from an onsite Groundwater Treatment System to an established
storm -sewer inlet adjacent SE to the site on Morehead Drive. 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]. If an analyte has an established surface water quality standard, DWR has
applied this standard as "limited" both as acute and chronic [see section A. (1.)].
Reasonable Potential Analyses (RPAs) -- Current databases reflect site -assessment from
monitoring wells and soil borings only. Therefore, in the absence of treated discharge data, no
RPA was conducted.
Whole Effluent Toxicity (WET) Testing -- This facility applies granular activated carbon (GAC)
filters as a final treatment to polish its effluent. Data show that these filters likely render the effluent too
clean to support aquatic life, a portent to WET -test failure [Cindy Moore, Aquatic Toxicology Branch
(DEQ/ATB)]. Therefore, consistent with current permitting guidance, WET testing of this proposed
discharge is not required.
6.0 ENGINEERING ALTERNATIVES ANALYSIS (EAA)
The Applicant's Engineering Alternatives Analysis (EAA) notes that a "positive streamflow"
historically exists for mainstem Little Sugar Creek (see Table 1 above), but they further assert that
its "unnamed tributaries (UTs) are similarly therefore not subject to zero flow stream restrictions."
Morehead Tryon appears to assume thereby that their proposed effluent at Outfall 001 may be
afforded dilution [see EAA Terracon, Step 1., 02Jun2022]. This is an incorrect assumption (see
above section 3.0).
The application includes supporting documents from local permitting Authorities. As required of
new discharges, the Applicant has presented an Engineering Alternatives Analysis (EAA),. The
EAA considered:
• land application
• connecting to an existing WWTP
• installing infiltration galleries
• wastewater reuse
• off -site disposal via vacuum truck, and
• direct discharge to surface waters including an
evaluation of potential impacted species.
Morehead Tryon concludes that "off -site disposal via vacuum truck," and "direct discharge to
surface waters" remain as the only alternatives due to a restrictively dense urban environment
surrounding the site, and further that groundwater (treated or otherwise) is unacceptable to local
wastewater treatment plants (WWTPs). Thus, discharge alternatives are restricted to two viable
options only.
Present -Value Costs were thereby estimated for Batch and Haul = $275,000 and for Discharge to
Surface Waters = $30,661. The Applicant concludes that a surface -water discharge is the most
viable discharge alternative based on cost (see Permittee's EAA Present Value Cost, Memorandum
Step 5.). DWR concurs with this conclusion.

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, 7Q10 (the spreadsheet automatically
calculates the 1Q10 using the formula 1Q10 = 0.843 (s7Q10, cfs) 0.993
• Effluent hardness and upstream hardness, site -specific data is preferred
• Permitted flow
• Receiving stream classification
2. In order to establish the numeric standard for each hardness -dependent metal of concern
and for each individual discharge, the Permit Writer must first determine what effluent and
instream (upstream) hardness values to use in the equations.
The permit writer reviews DMR's, Effluent Pollutant Scans, and Toxicity Test results for
any hardness data and contacts the Permittee to see if any additional data is available for
instream hardness values, upstream of the discharge.
If no hardness data is available, the permit writer may choose to do an initial evaluation
using a default hardness of 25 mg/L (CaCO3 or (Ca + Mg)). Minimum and maximum
limits on the hardness value used for water quality calculations are 25 mg/L and 400 mg/L,
respectively.
If the use of a default hardness value results in a hardness -dependent metal showing
reasonable potential, the permit writer contacts the Permittee and requests 5 site -specific
effluent and upstream hardness samples over a period of one week. The RPA is rerun using
the new data.
The overall hardness value used in the water quality calculations is calculated as follows:
Combined Hardness (chronic) =
(Permitted Flow, cfs *Avg. Effluent Hardness, mg/L) x (s7Q10, cfs *Avg. Upstream Hardness, mg/L)
(Permitted Flow, cfs + s7Q10, cfs)
The Combined Hardness for acute is the same but the calculation uses the 1Q10 flow.
3. The permit writer converts the numeric standard for each metal of concern to a total
recoverable metal, using the EPA Default Partition Coefficients (DPCs) or site -specific
translators, if any have been developed using federally approved methodology.
Fact Sheet
Morehead Tryon Land LP -- NEW NPDES Permit NC0090123
Page 6 of 8

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] [SS0+0] [ 10-6] }
Where:
ss = in -stream suspended solids concentration [mg/1], minimum of 10 mg/L used,
and Kpo and a = constants that express the equilibrium relationship between
dissolved and adsorbed forms of metals. A list of constants used for each hardness -
dependent metal can also be found in the RPA program under a sheet labeled DPCs.
4. The numeric standard for each metal of concern is divided by the default partition
coefficient (or site -specific translator) to obtain a Total Recoverable Metal at ambient
conditions.
In some cases, where an EPA default partition coefficient translator does not exist (ie.
silver), the dissolved numeric standard for each metal of concern is divided by the EPA
conversion factor to obtain a Total Recoverable Metal at ambient conditions. This method
presumes that the metal is dissolved to the same extent as it was during EPA's criteria
development for metals. For more information on conversion factors see the June, 1996
EPA Translator Guidance Document.
5. The RPA spreadsheet uses a mass balance equation to determine the total allowable
concentration (permit limits) for each pollutant using the following equation:
Ca = (s7Q10 + Qw) (Cwqs) — (s7Q10) (Cb)
Qw
Where: Ca = allowable effluent concentration (µg/L or mg/L)
Cwqs = NC Water Quality Standard or federal criteria (µg/L or mg/L)
Cb = background concentration: assume zero for all toxicants except NH3* (µg/L or
mg/L)
Qw = permitted effluent flow (cfs, match s7Q 10)
s7Q10 = summer low flow used to protect aquatic life from chronic toxicity and
human health through the consumption of water, fish, and shellfish from
noncarcinogens (cfs)
* Discussions are on -going with EPA on how best to address background
concentrations
Flows other than s7Q10 may be incorporated as applicable:
1Q10 = used in the equation to protect aquatic life from acute toxicity
QA = used in the equation to protect human health through the consumption of
water, fish, and shellfish from carcinogens
30Q2 = used in the equation to protect aesthetic quality
Fact Sheet
Morehead Tryon Land LP -- NEW NPDES Permit NC0090123
Page 7 of 8

6. The permit writer enters the most recent 2-3 years of effluent data for each pollutant of
concern. Data entered must have been taken within four and one-half years prior to the date
of the permit application (40 CFR 122.21). The RPA spreadsheet estimates the 95th
percentile upper concentration of each pollutant. The Predicted Max concentrations are
compared to the Total allowable concentrations to determine if a permit limit is necessary.
If the predicted max exceeds the acute or chronic Total allowable concentrations, the
discharge is considered to show reasonable potential to violate the water quality standard,
and a permit limit (Total allowable concentration) is included in the permit in accordance
with the U.S. EPA Technical Support Document for Water Quality -Based Toxics Control
published in 1991.
7. When appropriate, permit writers develop facility specific compliance schedules in
accordance with the EPA Headquarters Memo dated May 10, 2007 from James Hanlon to
Alexis Strauss on 40 CFR 122.47 Compliance Schedule Requirements.
8. The Total Chromium NC WQS was removed and replaced with trivalent chromium and
hexavalent chromium Water Quality Standards. As a cost savings measure, total chromium
data results may be used as a conservative surrogate in cases where there are no analytical
results based on chromium III or VI. In these cases, the projected maximum concentration
(95th %) for total chromium will be compared against water quality standards for
chromium III and chromium VI.
9. Effluent hardness sampling and instream hardness sampling, upstream of the discharge, are
inserted into all permits with facilities monitoring for hardness -dependent metals to ensure
the accuracy of the permit limits and to build a more robust hardness dataset.
10. Hardness and flow values used in the Reasonable Potential Analysis for this permit

Terracon Project No. 71227087
Dear Mr. Thetford:
On behalf of Morehead Tryon Land LP, Terracon Consultants, Inc. (Terracon) has completed
the enclosed NPDES Permit Application and supporting documentation for the above -
referenced property. Preparation of this NPDES Individual permit application is associated with
proposed dewatering that will be necessary during and after the construction of three high-rise,
mixed use towers at the site, which will include a 2- or 3-story below grade parking structure that
intersect will intersect the water table. Limited groundwater impacts have been identified at the
site, apparently the result of petroleum release(s) from former underground storage tanks
located adjacent to the existing Uptown Cabaret building in the northern portion of the site.
Morehead Tryon Land LP proposes to pre -treat the groundwater that is dewatered from the
sub -grade parking structure and then discharge the effluent to the Charlotte -Mecklenburg
County municipal stormwater sewer, with ultimate discharge occurring to Little Sugar Creek,
under a new individual NPDES permit.
As noted on EPA Forms 3510-2D and 3510-2E, Morehead Tryon Land LP is requesting a
waiver for the following effluent characteristics: biochemical oxygen demand, chemical oxygen
demand, total organic carbon, ammonia, and oil and grease. These parameters, and the
remaining listed in Table A of Form 3510-2D and Section 4.2 of Form 3510-2E (total suspended
solids, discharge flow, pH, and temperature), have not been collected. As the discharge in
question will be composed solely of groundwater, it is not anticipated that the effluent will
contain constituents that would have an impact on biochemical oxygen demand, chemical
oxygen demand, total organic carbon, ammonia, or oil and grease. As such, we respectfully
request that these parameters be waived from effluent monitoring requirements.

SECTION 8. NATURE OF BUSINESS (40 CFR 122.21(f)(8))
8.1
Nature of Business
Describe the nature of your business.
Morehead Tryon Land LP plans to redevelop the facility property (currently developed with a gentleman's club
building, a restaurant, and the associated paved parking areas) with a three mixed -use high-rise towers. The towers
will be underlain by a 2- to 3-story tall sub -grade parking feature that will intersect the groundwater table.
Groundwater at site has been impacted by petroleum contamination associated with an apparent release(s) from
former underground storage tank systems located adjacent to the gentleman's club building in the northern portion
of the site. As dewatering will be necessary during construction and permanently to prevent infiltration from
flooding the sub -grade parking feature, Morehead Tryon Land LP would like authorization to pre -treat dewatered
groundwater and discharge it to the stormwater sewer.
SECTION 9. COOLING WATER INTAKE STRUCTURES (40 CFR 122.21(f)(9))

Does your facility use cooling water?
❑ Yes E No 4 SKIP to Item 10.1.

40 CFR 125, Subparts I and J may have additional application requirements at 40 CFR 122.21(r). Consult with your
NPDES permitting authority to determine what specific information needs to be submitted and when.)
Not applicable; while the high rise towers may utilize HVAC systems that utilize chilled water, the proposed
discharge will consist solely of groundwater.
SECTION 10. VARIANCE REQUESTS (40 CFR 122.21(f)(10))
10.1
Do you intend to request or renew one or more of the variances authorized at 40 CFR 122.21(m)? (Check all that
apply. Consult with your NPDES permitting authority to determine what information needs to be submitted and
when.)

Briefly describe the frequency and duration of flow.
The discharge will result from the temporary dewatering of caisson boreholes and excavation for subgrade foundation
construction. The subgrade foundation is designed to intersect the reported groundwater surface elevation with
approximately 153,900 square feet of floor area 2 feet below static water table level. Terracon is assuming a maximum
flow rate for temporary construction dewatering at 112 gallons per minute (GPM). Flow is anticipated to be
significantly below this rate because only small areas associated with construction progress would require dewatering.

DATE: June 2, 2022
RE: Engineering Alternatives Analysis — Morehead Tryon Land LP NPDES Permit,
111 East Morehead Street, Charlotte, Mecklenburg County, North Carolina
Description of Proposed Project
Terracon was retained by Morehead Tryon Land LP to prepare an Engineering Alternatives
Analysis (EAA) for the site located at 111 East Morehead Street in Charlotte, North Carolina.
The site consists of six (6) contiguous tax parcels (Parcel Nos. 123-012-02, 123-012-03, 123-
012-05, 123-012-06, 123-012-07 and 123-0140-01.) totaling approximately 2.74 acres. The
northernmost parcel is developed with an 11,298 sq. ft. nightclub/lounge building which
operates as The Uptown Cabaret. The south -westernmost parcel is developed with a 2,964 sq.
ft. restaurant building which operates as Midnight Diner. The remainder of the site includes
paved parking lots and access drives. The site location and layout are shown on Exhibits 1
and 2 of the permit application.
Morehead Tryon Land LP plans to redevelop the site with three mixed -use high-rise towers
which will overlay an approximate 2- to 3-story sub -grade parking structure. Limited
groundwater impacts have been identified at the site (see Table 1 and Exhibit 2), apparently
the result of petroleum release(s) from former underground storage tanks located adjacent to
the existing Uptown Cabaret building in the northern portion of the site. Morehead Tryon Land
LP proposes to pre -treat the groundwater that is dewatered during construction activities and
then discharge the effluent to the Charlotte -Mecklenburg County municipal stormwater sewer,
with ultimate discharge occurring to Little Sugar Creek, under a new individual NPDES permit.
Preparation of this EAA has been completed in conjunction with a NPDES application for the
proposed discharge of pre-treated groundwater associated with Morehead Tryon Land LP's
proposed construction. A description of the proposed project follows. Projections for flow,
evaluation of technical and financial feasibility, and Local Government Review are provided in
later sections.

STEP 1. Determination of Discharge Permit Eligibility
Terracon has reviewed the potential restrictions identified in the EAA guidance document and
does not believe that the identified restrictions will pose an impediment to an NPDES discharge
from this location, as discussed below. The discharge will be to Little Sugar Creek and will occur
after the groundwater has been treated.
1) Zero Flow Stream Restrictions
According to the United States Geological Survey (USGS), Little Sugar Creek, the receiving stream
for the proposed discharge, is not a zero -flow stream. As such, Little Sugar Creek is not subject to
zero -flow stream restrictions. A copy of USGS correspondence providing flow estimates is included
as an attachment to this memo. Please note while the correspondence is in response to a prior
inquiry associated with a different project/proposed discharge (Radius Overlook Dilworth; 615 East
Morehead Street), the Queensbridge Collective project (111 East Morehead Street) is located
Charlotte, NC
Environmental • Facilities • Geotechnical • Materials

lierracon
Memorandum
approximately 1,700 feet northwest of the Radius Overlook Dilworth project and is also located
within the Upper Little Sugar Creek watershed. As such, the proposed discharge will also enter Little
Sugar Creek at a similar location and the USGS-provided flow characteristics provided in December
2021 are applicable for the Queensbridge Collective project.
2) Receiving Stream Classification
According to NCDEQ DWR's online surface water classifications map, the receiving stream for the
proposed discharge, Little Sugar Creek, is a Class C water. Class C waters are not subject to
discharge restrictions and/or stricter treatment standards such as those that may be required for
certain stream classifications (e.g. ORW, WS, SA, NSW, and HQ).
2) Basinwide Water Quality Plan
According to the most recent Catawba River Basinwide Water Quality Plan (2010), Little Sugar
Creek is listed as impaired for copper, mercury, and turbidity standards as well as biological integrity
of fish and benthic communities (page 3.12 of the Plan). The Basinwide Plan includes total
maximum daily load (TMDL) restrictions (see Item # 3 below for more information regarding TMDLs)
to limit wastewater discharge within the Catawba River Basin. The Basinwide Plan indicates that
Little Sugar Creek is subject to TMDLs for turbidity and fecal coliform bacteria (FCB; page 3.13 of
the Plan). It should be noted that the Basinwide Plan also indicates that during the TMDL study
window (1997 to 2004), Little Sugar Creek turbidity did not exceed the applicable turbidity standard
and that the TMDL in question only covers Long Creek (page 1.43 of the Plan).
3) Impaired Waters and TMDLs
According to a Final Report issued by NCDEQ in 2005 establishing TMDLs for turbidity within the
Catawba River Basin, the TMDL for turbidity is only applicable to the portion of Little Sugar Creek
between North Carolina Highway 51 and the North Carolina -South Carolina state line, which begins
approximately 8 miles south of the site. As such, the proposed discharge to Little Sugar Creek is not
limited by an established TMDL.
According to a Final Report issued by NCDEQ in 2002 establishing TMDLs for FCB in four
watersheds within Mecklenburg County, the entirety of Little Sugar Creek from its source to the state
line is subject to the FCB TMDL. The proposed discharge is not a potential source of FCB, as it
originates as dewatered groundwater generated during installation of deep foundations at a
construction site. As such, the proposed discharge will not result in FCB impact to Little Sugar Creek
or result in exceedance of the established TMDL.
A TMDL was also established for dissolved oxygen (DO) in Little Sugar Creek in 1996. The
proposed discharge is not expected to significantly affect the DO within Little Sugar Creek, as it is
composed of groundwater from dewatered foundation installation activities in an urban area and it is
not expected to be loaded with nutrients such as phosphorus and nitrate that would reduce DO.
Further, the effluent will be treated on -site via carbon filtration prior to discharge. This carbon
Charlotte, NC
Environmental • Facilities • Geotechnical • Materials

lierracon
Memorandum
filtration will remove volatile organic compounds that could be utilized by microbes within Little Sugar
Creek as a food source, the metabolisms of which would also consume oxygen and lower DO. As
such, the DO TMDL should not limit the proposed discharge.
4) Presence of Endangered Species
According to the USFWS Information for Planning and Consultation (iPAC) online system, the
following listed endangered species are potentially present in the general region of the site and
down -stream portions (within approximately 3 miles of the proposed discharge point) of Little Sugar
Creek: Michaux's Sumac (flowering plant), Schweinitz's Sunflower (flowering plant), Smooth
Coneflower (flowering plant), Northern Long-eared Bat (mammal), Monarch Butterfly (insect), and
Carolina Heelsplitter (clam). In addition, a number of migratory birds are listed in the iPAC
information. As the Carolina Heelsplitter is the only aquatic species potentially present in Little Sugar
Creek, there would be no expected impact to the other species listed above. According to the most
recent Catawba River Basinwide Water Quality Plan (2010), the only stream in the Catawba River
basin that supports populations of the Carolina Heelspliter is Waxhaw Creek (page 3.16 of the Plan),
which enters the Catawba River some 30 miles south of the point of proposed discharge to Little
Sugar Creek. As such, there would be no expected impact to the Carolina Heelsplitter from the
proposed discharge. A summary of the iPAC endangered species information is included as an
attachment to this letter.
STEP 2 . Determination of Discharge Permit Eligibility
A. Summary of Process Information and Flow Estimates
The discharge will result from the temporary dewatering of caisson boreholes and excavation for
subgrade foundation construction. The boreholes will range in diameter from 2.5 feet to 6 feet
and will be advanced via auger rotary and rock core methods. A temporary casing will be driven
ahead of the drill tooling to limit infiltration of the groundwater into the borehole. Once a
borehole has reached the appropriate depth, it is anticipated that the borehole will remain open
for a maximum of approximately one day prior to the installation of the concrete caisson via
tremie pipe. Based on Terracon's geotechnical experience in the Charlotte area, groundwater is
typically encountered within boreholes that are allowed to remain open overnight at the
approximate expected depth of the water table based on the Iithological conditions observed in
the cuttings (e.g. saturated soil conditions). As such, Terracon conservatively assumes that
groundwater will rise to the depth of the water table within the boreholes prior to caisson
installation. Caissons are planned to be installed one at a time, with construction crews finishing
one before moving to the next. The subgrade foundation is designed to intersect the reported
groundwater surface elevation with approximately 153,900 square feet of floor area 2 feet below
static water table level. Based on the caisson drilling schedule and dewatering to 2 feet below
Charlotte, NC
Environmental • Facilities • Geotechnical • Materials

lrerracon
Memorandum
groundwater surface elevation for the subgrade foundation construction, Terracon is assuming a
maximum flow rate for temporary construction dewatering at 112 gallons per minute (GPM).
Groundwater will be directed into a frac tank which discharges into a treatment train consisting
of bag filtration (to remove sediment) and a steel vessel containing 8,000 pounds of reactivated
carbon, as detailed in the NPDES permit application. The technical specifications of the
treatment system are provided in Appendix D of the permit application. Please note that while
the proposed pre-treatment is not considered a groundwater remediation treatment for the
purposes of reducing petroleum concentrations of impacted groundwater within the subsurface
at the site, for the purposes of this EAA and the NPDES Permit Application, it is referred to as a
groundwater remediation system below.
Terracon anticipates that the maximum discharge during working days will be approximately
112 GPM. Per the carbon filter manufacturer, the system should be operated at above 50 GPM
to minimize channeling within the carbon vessel. As such, the system will be operated to
maintain an average flow rate between 50 and 112 GPM. Flow rates will be intermittent, not
continuous, based on construction phasing and groundwater infiltration.
B. Low Flow Data for Receiving Stream
Low flow information for the receiving water(s) was obtained from the US Geological Society
(USGS)and the NCDEQ in Raleigh, North Carolina. Correspondence from the agencies is
provided in Attachment A. Generally, the discharge from the system will be directed to a
designated outfall through underground piping. From the point of discharge, underground piping
discharges to a topographic depression in which stormwater ultimately flows into Little Sugar
Creek. The USGS provided the following low -flow statistics based on a period of analysis of
1995 through 2011 climatic years:
Frequency Discharge
7Q10 1.5 cubic feet per second (cfs)
30Q2 4.0 cfs
W7Q10 2.3 cfs
7Q2 2.5 cfs
Based on the USGS-provided information, Little Sugar Creek is not considered a zero -flow
stream and is therefore not subject to zero -flow stream restrictions as set forth in 15A NCAC
2B.0206(d)(2).

llerracon
Memorandum
STEP 2. Reasonable Projections for Flow
As discussed in the EAA Guidance Document, non —municipal flow projections for groundwater
remediation projects are based on engineering design considerations and/or production
projections rather than population projections. As discussed in Step 1C above, the anticipated
maximum flow associated with the temporary construction dewatering activities will be
approximately 112 GPM. As there currently is no firm projection for the phases of construction,
the flow rate is based on the calculation of hydraulic conductivity and infiltration into the
maximum floor area anticipated to be below the groundwater elevation during construction
activities — 2 feet saturated at 153,900 square feet. Flow rates will be intermittent, not
continuous, based on construction phasing and groundwater infiltration.
STEP 3. Evaluate Technologically Feasible Alternatives
As discussed in the EAA Guidance Document, discharges from groundwater remediation
systems are required to evaluate whether wastewater treatment plant (WWTP) connection, land
application, infiltration galleries, in -situ groundwater remediation wells, or closed -loop
groundwater remediation wells. As these alternatives have not been deemed technologically
feasible, as discussed below, Terracon has also considered closed -wastewater reuse,
discharge to surface waters, and combinations of the above as possible alternatives.
A. Connection to an Existing WWTP
The Charlotte -Mecklenburg Utilities (CMU) has discontinued accepting groundwater discharges.
Specifically, the City of Charlotte Sewer Use Ordinance prohibits the discharge of groundwater
in Section 23-79 (14) without permission from the CMU-System Protection (SP). Based on
conversations with representatives of SP, CMU will not accept discharge of the dewatered
groundwater, making this treatment alternative infeasible.
B. Land Application
The facility is located at 111 East Morehead Street in Charlotte, North Carolina. This location is
just outside Uptown Charlotte in an urban area consisting predominantly of commercial
development. Ground cover in the area is predominantly already developed hardscape. Land
application of the discharge would interfere with construction. Based on the design and land
constraints and the available land, land application is not feasible at this time.
Charlotte, NC

lrerracon
Memorandum
C. Infiltration Galleries
As discussed above, there is not space on the site to install an infiltration gallery. As such,
infiltration galleries are not a technologically feasible alternative.
D. In -Site or Closed -Loop Groundwater Remediation Wells
As the proposed discharge is temporary, and it would be difficult to protect/maintain wells on an
active construction site, permanent re -injection well infrastructure is unnecessary and not
technically feasible.
E. Wastewater Reuse
The site will consist of an active construction site during the dewatering activities. As such, there
are no site processes available in which the dewatered groundwater could be reused.
Therefore, wastewater reuse is not technically feasible.
F. Off -site Disposal of Discharge via Vacuum Truck
The off -site disposal of temporarily containerized dewatered groundwater via vacuum truck
("batch and haul") is a technologically feasible alternative for disposal. However, as discussed in
Step 5 below, it is not an economically feasible alternative compared to NPDES surface water
discharge.
G. Direct Discharge to Surface Waters
Surface water discharge has been determined to be a technically feasible alternative for
disposal of the dewatered groundwater based on the presence of Charlotte -Mecklenburg
stormwater infrastructure at/adjacent to the site and its ultimate discharge to surface water. The
discharge from the outlet of the treatment system will be directed into a stormwater intake
located in an existing stormwater detention basin located at the southeast boundary of the
property along Morehead Square Drive. Treated flow from dewatering activities ultimately
discharges into Little Sugar Creek. Refer to Exhibit 1 for the approximate and location of the
facility in relation to the Little Sugar Creek. Exhibit 2 shows the location of designated Ouffall
#1.

Memorandum
STEP 5. Evaluate Economically Feasible Alternatives
"Batch and haul" and surface water discharge have been determined to be the only technically
feasible alternatives for disposal of dewatered groundwater. As the proposed discharge is
temporary and will only occur during an approximate 4-month period during 2022/2023, a 20-
year present value cost analysis (PVCA) has not been completed. However, Terracon has
completed a comparison of the overall projected costs of the two identified technologically
feasible alternatives. Below is a table comparing costs for the disposal of the dewatered
groundwater via "batch and haul" versus surface water discharge under a NPDES Individual
Permit. The costs are estimates and are limited to those elements specific to the discharge, e.g.
operational requirements, treatment costs, monitoring costs and maintenance. As the disposal
facility will require characterization sampling of groundwater exported from the site via "batch
and haul," and periodic sampling of pre-treated groundwater discharge is anticipated under the
NPDES permit requirements, it has been assumed that the difference in sampling costs (labor
and laboratory analysis) is negligible. In addition, as dewatered groundwater will be
containerized within a rented frac tank in either scenario, its cost has not been included in the
table below.

permit is by far the most economically feasible option for disposal of the dewatered groundwater
at the site.

Subject: USGS response to DWR USGS Low Flows request # 2022-163 (dated 2021/11/23) for
Little Sugar Creek Mecklenburg County...RE: [EXTERNAL) Low -flow request approval
Mr. Frazier,
In response to your inquiry about the low -flow characteristics for a location immediately upstream from USGS Sta.
02146409 Little Sugar Creek at Medical Center Drive at Charlotte (station id 02146409, NWIS drainage area 11.8 sqmi) in
downtown Charlotte in Mecklenburg County, the following information is provided:
A check of the low -flow files here at the USGS South Atlantic Water Science Center (Raleigh office) indicates the point of
interest is located immediately upstream from a USGS continuous -record streamgage on Little Sugar Creek, as identified
by the lat/long coordinates (35.20361, -80.83694) provided via email dated 11/23/2021 from the DWR USGS Low Flow
portal following your request submission.
A basin delineation completed using the online USGS StreamStats application for North Carolina
(https://streamstats.usgs.gov/ss/) indicates the drainage area for the point of interest (StreamStats adjusted
coordinates 35.20360, -80.83711 NAD83) is 12 sqmi.
For streams in Mecklenburg County, low -flow characteristics published by the USGS are provided in the following
reports:
(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 most recent USGS statewide low -flow report (#2 above -referenced report) indicates the low -flow
characteristics for this streamgage were published. In table 3 on page 26 of this report, the following low -flow statistics
are provided:
Period of analysis: 1995-2011 climatic years
1

Annual 7Q10 discharge = 1.5 cfs
Annual 30Q2 discharge = 4.0 cfs
Annual winter 7Q10 (W7Q10) discharge = 2.3 cfs
Annual 7Q2 discharge = 2.5 cfs
Annual average discharge = 19.2 cfs (period of analysis 1995-2012 water years, table 5 on page 83)
Please note:
(1) The estimated flows are provided in units of cubic feet per second per square mile drainage area (cfsm).
(2) The climatic year is the standard period used for low -flow analyses at USGS continuous -record
streamgages. The climatic year is from April 1 through March 31, designated by the year in which the period
begins. For example, the 2011 climatic year is from April 1, 2011, through March 31, 2012.
Again, please understand 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 USGS and the N.C. Department of Environmental Quality, Division of Water Resources.
Hope this information is helpful.
Thank you.

DESCRIPTION
TIGG 5DR 0830
Reactivated Liquid Phase
Coal Based Activated Carbon
TIGG 5DR 0830 granular activated carbon made from selected grades of bituminous coal,
which has been thermally reactivated. Depending upon the application, this activated
carbon can provide performance similar to virgin activated carbon at a reduced cost.
TYPICAL PROPERTIES TIGG 5DR 0830
U.S Sieve, 90 wt% min 8 x 30*
Iodine Number, mg/g 750
Apparent Density, (dense packing)
g/cc 0.45 - 0.55
Ibs/ft3 28 - 34
Moisture - wt% max (as packed) 2
Abrasion No. - min
* Size 840 is also available
TYPICAL APPLICATIONS
70
This activated carbon can be used to remove:
• BTEX and other organic compounds from ground water.
• Organic compounds from wastewater and potable water.
• Trace organics from process streams such as alcohols, glycerine, MEA, acids, etc
Standard packaging of the activated carbon is in 50 pound bags or 1000 pound supersacks.
Wet drained activated carbon adsorbs oxygen from the air. Therefore, when workers need to enter a vessel containing
wet activated carbon, they should follow confined space/low oxygen level procedures. Activated carbon dust does not
present an explosion hazard.

Subject: NPDES Permit Application - request to discharge into the City of Charlotte municipal
stormwater system at 1111 South Tryon Street in Charlotte, NC
Division of Water Resources:
Regarding Terracon's request on behalf of Morehead Tryon Land LP 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,
Morehead Tryon Land LP Or its consultant shall immediately notify CMSWS and
immediately implement corrective actions.
• CMSWS reserves the right to rescind approval to discharge to the City of Charlotte's MS4 for
due cause including gross improper operation of the system, and established trend of
discharge limit exceedances, failure to provide notification of illicit discharges, 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 or concerns, please contact Andrew DeCristofaro at [phone].
