B. Project Description
o 230 North Tryon, LLC is renovating the historic Carolina Theatre. Plans call for
restoring the theater and its original facade behind a new "jewel box" glass
exterior, which will frame a new lobby. In addition, a 20-story hotel is planned
above the existing 5-story theatre. During the course of construction,
groundwater may be encountered during excavations for foundations and
elevator shafts. Historical groundwater monitoring data indicates that several
volatile organic compounds (VOCs) were detected in groundwater samples
collected from the site in in 2006 and 2007 at concentrations above North
Carolina groundwater standards including carbon tetrachloride (maximum
concentration of 1,200 micrograms per liter [ug/I]), chloroform (maximum
concentration of 1,740 ug/l), 1,2-dichloropropane (maximum concentration of
2.1 ug/l),and tetrachloroethene(maximum concentration of 1.2 ug/I. Analytical
results for a groundwater sample collected on June 1, 2018 indicate detectable
concentrations of VOCs below North Carolina groundwater standards including
acetone (at a maximum concentration of 3.9 ug/l), acrylonitrile (at a maximum
concentration of 2.7 ug/I), and chloroform (at a maximum concentration of 11
ug/l). Appendix A includes summary tables of the 2006, 2007, and 2018
groundwater analytical data.

o It is not clear if groundwater will be encountered during construction activities.
Nor is it clear, if groundwater is encountered, if it will contain concentrations of
VOCs which would prohibit the discharge of such groundwater to surface water
under North Carolina surface water standards. 230 North Tryon, LLC desires to
have a valid NPDES permit in the event groundwater is encountered. . If
groundwater is encountered, 230 North Tryon, LLC proposes to remove it from
excavations using sump pump(s)which will discharge to a settling/holding tank.
A float actuated pump located downstream of settling/holding tank will move
water through two bag filter aligned in series and through two granular
activated carbon (GAC) vessels aligned in series. Each GAC vessel will contain a
minimum of 250 pounds of GAC. GAC breakthrough is expected to occur
approximately 60 days after startup based upon VOC loading associated with
the maximum concentrations of VOCs detected in groundwater in 2006 and
2007 and a design flow rate of 20 GPM. Appendix B is a schematic drawing of
the proposed treatment equipment. The stormwater system discharges to an
unnamed tributary to Irwin Creek north of the subject site at latitude 35.233595
north and longitude 80.846685 west.
o The dewatering activity and proposed discharge is expected to occur over a
period of one month to no more than one year.
o 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.
Although a determination has been made by the United States Geological
Survey (USGS) that the unnamed tributary to Irwin Creek where the discharge
will occur is most likely a zero- flow stream under 7Q10 conditions, this
restriction is not applicable because the wastewater is not an oxygen-
consuming waste. A copy of the USGS report on streamflow characteristics
is attached as Appendix C.
➢ Receiving stream classification restrictions (e.g., ORW, WS, SA, NSW, and HQ class waters
have various discharge restrictions or require stricter treatment standards).
v ECS determined that the stream classification for Irwin Creek is Class C by
reviewing data on NCDEQ's stream classification webpage on August 3, 2018.
Therefore, this restriction is not applicable. Appendix D includes a screenshot
NCDEQ's stream classification webpage.
5

➢ 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.
➢ ESC reviewed the 2007 final draft basin specific water quality plan for the
Catawba River Basin basin found through the NCDEQ website
at https://www.ncwater.org/files/publications/Final Draft Catawba River Basi
n Plan 2007.pdf. This document does not contain any specific discharge
recommendations for Irwin Creek. ESC contacted Ms. Pamela Behm of the
NCDEQ, Division of Water Quality, Modelling and Assessment Branch. Ms. Behm
forwarded an email on August 6, 2018 in which she indicated that no Total
Maximum Daily Loads (TDMLs) are planned for Irwin Creek. Appendix E
includes a copy of the referenced email.
➢ 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.
➢ ESC reviewed the 303(d) list found through the NCDEQ website
(https://files.nc.gov/ncdeq/Water%20Quality/Planning/TM DL/303d/2016/2016
NC Category 5 303d list.pdf). This document indicates the Irwin Creek from
the source to Sugar Creek is listed as impaired because of issues with metals
(specifically copper, lead, and zinc). An excerpt of this document is included
as Appendix F. ESC contacted Ms. Pamela Behm of the NCDEQ, Division of
Water Quality,Modelling and Assessment Branch. Ms. Behm forwarded an email
on August 6, 2018 in which she confirmed that Irwin Creek is impaired due to
issues with metals(specifically copper, lead, and zinc). She also indicated that
no Total Maximum Daily Loads(TDMLs) are planned for Irwin Creek. 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.
ESC contacted the North Carolina Wildlife Resource Commission by email. On August
27, 2018, Ms. Olivia Munzer responded by email and indicated that this agency has
no records of state- or federally-listed rare, threatened, or endangered species
downstream of the proposed discharge point. Appendix E includes copies of email
correspondence with this individual with this agency.
STEP 2-PROVIDE REASONABLE PROJECTIONS FOR POPULATION AND FLOW
According to information from the North Carolina Office of State
Budget and Management found on the internet
at https://files.nc.gov/ncosbm/demog/countvgrowth 2020.html the population of
Mecklenburg County was 919,637 in April 2010 and is projected to increase to 1,143,547
by July 2020.
➢ Based upon experience at similar construction dewatering projects in Charlotte, ECS
estimates flow from the proposed project will be 28,800 gallons per day(GPD) or less(or
approximately 20 gallons per minute [GPM] or 0.0288 million gallons per day [MGD]).
6

STEP 3-EVALUATE TECHNOLOGICALLY FEASIBLE ALTERNATIVES
Connection to an existing wastewater treatment plant(public or private)
• 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.
➢ Land application alternatives, such as individual/community onsite subsurface
systems,drip irrigation,spray irrigation and/or high rate infiltration galleries
• The subject site is located on a parcel which is less than 95 feet wide (parallel to Tryon
Street) and less than 192 feet deep parallel to 6th Street). The total area of the parcel
is 0.434 acres. There is insufficient land on the subject site to meet the setback
requirements listed in 15A NCAC 02T.0506 and 15A NCAC 02T.0706. The cost of land
in the immediate area is financially prohibitive to obtain for this project. The property
located immediately south of southwest of the subject property is occupied by the
Hearst Tower complex. The tax value for this 2.34-acre parcel is$5.75 Million. The tax
value of the 0.37-acre parcel located immediately to the southwest of the subject
property has a tax value of approximately$6.7 million. Copies of property tax cards are
attached in Appendix H. In addition to land acquisition costs, there would be costs to
demolish existing buildings.
➢ Wastewater reuse
• It is not practical to reuse the extracted groundwater on this project given the
expected limited duration of the project and
➢ Surface water discharge through the NPDES program
• ECS believes discharge to surface water through the NPDES program is the most
viable option for the proposed discharge given the expected short-term nature of the
project, prohibitions to other discharge options, and financial considerations. ECS is
aware of several similar construction dewatering projects in the area which NCDEQ
approved for NPDES discharges in recent years. These include the Charlotte Area
Transit System Construction project (Permit No. NC008371), the Myrtle/Morehead
Storm Drainage Improvement project (Permit No. NC0089443), Dimensional Place
Construction project (Permit No. NC0089656).
• Combinations of the aforementioned alternatives
• 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.
7

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 for each technologically feasible alternative identified in Step 3.
As indicated in Step 3, ECS believes discharge to surface water through the NPDES program is the
most viable option for the proposed discharge given the expected short-term nature of the project,
prohibitions to other discharge options, and financial considerations. No other alternative appear
viable. The 20-year PVCA does not appear valid for the alternative of discharge to surface water
through the NPDES program because of the expected short duration of the discharge (one month to
no more than one year). None-the-less, Appendix I includes a 20-year PVCA for the one feasible
alternative, discharge to surface water through the NPDES program. ESC followed NCDEQ
guidelines for the Engineering Alternatives Analysis including an assumed 20-year project life. Mr.
Bing Bai of NCDEQ indicated to ESC that a discount rate of 4.875 percent should be used in the
analysis.
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.
On September 13, 2018, ECS forwarded letter to the City of Charlotte and to Mecklenburg County in
which it requested these government entities to complete and return the Local Government Review
Form. ECS has not received responses from either of the two local government entities at this time.
Appendix J 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 received
within the specified time. (If ECS receives responses from either of these entities, it will forward them to
NCDEQ.)
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.

DESCRIPTION OF LOW-FLOW CHARACTERISTICS FOR UNNAMED TRIBUTARY TO IRWIN IN
CHARLOTTE, NORTH CAROLINA PREPARED BY J. CURTIS WEAVER OF THE UNITED STATES
GEOLOGICAL SURVEY-SEPTEMBER 4, 2018

Joseph Patrick Nestor
From: Weaver, John <[e-mail]>
Sent: Tuesday, September 4, 2018 11:16 AM

Subject: Response from USGS concerning...Re: [EXTERNAL] Discharge data - Carolina Theatre
Mr. Nestor,
In response to your inquiry about the low-flow characteristics(7Q10,30Q2,average annual discharge)for an unnamed tributary to Irwin
Creek adjacent to West 6th Street in Charlotte in central 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)does not indicate a previous low-flow
determination for the point of interest,as identified by the final lat/long coordinates(35.233595,-80.846685)provided in your email dated
August 30,2018.
No USGS discharge records are known to exist for the point of interest.
In the absence of site-specific discharge records sufficient for a low-flow analysis,estimates of low-flow characteristics at ungaged locations
are determined by assessing a range in the low-flow yields(expressed as flow per square mile drainage area,of cfsm)at nearby sites where
such estimates have previously been determined.
A basin delineation completed using the online USGS StreamStats application for North Carolina
(http://water.usgs.gov/osw/streamstats/north carolina.html)indicates the drainage area for the point of interest(35.23363,-80.84669
NAD83)is 0.19 sqmi.
For streams in central 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 http://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 http://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.
Inspection of the second report indicates the presence of eight(8)selected nearby USGS continuous-record streamgages within the upper
Sugar and Irwin Creek basins in close proximity of the point of interest where low-flow characteristics were published. Among these 8 sites,
the low-flow discharge yields for the indicated flow statistics are as follows:
Annual 7Q10 low-flow yields=_>from 0 to 0.41 cfsm(average about 0.1 cfsm,median 0.04 cfsm)
Annual 30Q2 low-flow yields=>from 0.11 to 0.66 cfsm(average 0.26 cfsm,median 0.17 cfsm)
Average annual discharge yields==>from 1.04 to 1.68 cfsm(average about 1.3 cfsm,median about 1.2 cfsm)
Application of the above range in yields to the drainage area(0.19 sqmi)for the point of interest results in the following estimated low-flow
discharges:
Annual 7Q10 discharges=_>from 0 to 0.08 cfs(average about 0.02 cfs,median about 0.01 cfs...rounded down to zero flow)
Annual 30Q2 discharges==>from 0.02 to 0.13 cfs(average about 0.05 cfs,median about 0.03 cfs)
Average annual discharge=>from 0.2 to 0.32 cfs(average about 0.25 cfs,median about 0.23 cfs)
1

Please note the estimated 7Q10 discharge is rounded down to zero flow given the uncertainty associated with estimates of this low
magnitude. The estimated 30Q2 discharge is likewise of a low magnitude,but is characterized as being less than minimal flow(less than
0.05 cfs).
Please also note that because your site is located in downtown Charlotte,it should be acknowledged the effects of development on low-flow
characteristics in urban basins have not been formally studied in the USGS North Carolina Water Science Center. There has been discussion
within the hydrologic community that development may reduce low-flow characteristics because increases in impervious areas reduce the
available surface area where infiltration of runoff can occur,thereby reducing the available base flow to streams during extended dry periods.
Please note the estimated flows are provided in units of cubic feet per second(cfs).
Please understand the information provided in this message is based on a preliminary assessment and considered provisional,subject to
revision pending further analyses.
Hope this information is helpful.
Thank you.

Mr. Weaver,
I did speak with Julie Grzyb of NCDEQ earlier this week, From that conversation, I understand that the flow
determination should be made at the point where the City of Charlotte's stormwater system discharges to the
unnamed tributary to Irwin Creek. The stream at this point has been channelized at this point with rock and masonry
sloping sidewalls. I have attached an aerial image from Google maps showing the discharge point as well as two
photographs of the unnamed stream near the discharge point. I have the lat/long for this point to be 35.233595/-
80.846685.
Thank you for your help.

ThankY ou Mr.Nestor.
Pending your conversation with NCDEQ and the final determination for the point of interest, I will hold on my
response to your request. I have pre-scoped the request and have assembled a list of nearby index streamgages
from the most recent USGS statewide low-flow report(Weaver, 2015)that will be used in the low-flow
computations.
During the pre-scoping, I discovered the lat/long coordinates(35.27244, -80.885178) for the point of interest
on Irwin Creek appear to be in error, placing the point of interest on Brookshire Boulevard just under a mile
north of the interchange at I-85. While I can correct for that based on your description in your initial email, I
will ask you to clarify these coordinates(for the record) if your point of interest is indeed on Irwin Creek.
And finally...please be prepared the estimated 7Q10 discharge for the unnamed tributary to Irwin Creek will
likely be minimal flow(less than 0.05 cfs), if not zero flow. Low-flow characteristics within urban and
developed basins often display wide variations in low-flow yields (flow per sqmi drainage basin). I have
already noted this in the group of nearby index streamgages in central Mecklenburg County.
When you are able to confirm(or clarify)the lat/long coordinates for the point of interest, I will be able to
complete a response to your request on fairly short order.
Thank you.

I am preparing an application for an NPDES discharge permit for a construction dewatering project
in downtown Charlotte. As part of the process the NCDEQ requires the applicant to obtain stream

flow statistics from the USGS. The NCDEQ guidance provided the 919-571-4000 telephone
number. I understand that NCDEQ is looking for 7Q10 and 30Q2 discharge data.
We propose to discharge to the Charlotte Stormwater system. The stormwater system discharges
to surface water in an unnamed tributary to Irwin Creek at latitude 35.233619 and longitude -
80.846612. This unnamed stream enters Irwin Creek at latitude 35.27244 and longitude -

Is this something you can help us with ?
I understand that there may be a fee associated with this determination. If so can you let us know
what that fee is?

Ms. Deaton:
I am working on a NPDES permit application for a construction dewatering project in downtown (or uptown if your
prefer) Charlotte. The NPDES permit branch 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 I am contacting you.
The NPDES permitting process requires that an Engineering Alternatives Evaluation (EAA) be performed. NCDENR
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
1

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).
Recent groundwater analysis of samples from a monitoring well constructed at the site did not indicate levels of
contaminants for which a NPDES permit would be required. Low levels of VOCs were detected in this sample (Acetone
3.9 ug/I; acrylonitrile 2.7 ug/I; and chloroform 11 ug/I) Furthermore, it is not certain that groundwater will be
encountered during construction. Higher concentrations of VOCs were detected in groundwater in samples collected
over ten years ago from the site. It is out an over-abundance of caution that we and our client are seeking an NPDES
permit.
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 suytem will
discharge to an unnamed tributary to Irwin Creek. Irwin Creek is within the Catawba River basin. We anticipate flow
rates of 10 gpm or 14,400 gpd or less.
I would like to determine if there are endangered species in the basin downstream of the discharge point which would
cause wastewater discharge restrictions with respect to the proposed discharge.
Would you or another member of your staff help me on this matter, please?
Thanks

As I mentioned in the voice mail I left you, I am working on a NPDES permit application for a construction dewatering

with the DWR Modeling and Assessment Branch to determine if your rules would impose restrictions for the proposed

I have attached guidance from the NPDES webpage which indicated we are to determine if"impending TMDLs may have
wastewater discharge restrictions." The guidance document suggests that the DWR Modeling and Assessment Branch
be contacted.

I have also attached a map showing where the discharge will occur and information regarding the latitude and longitude
on the discharge point to the tributary and latitude and longitude where the tributary enters Irwin Creek.
I reviewed the TMDL Interactive map
at https://ncdenr.maps.arcgis.com/apps/webappviewer/index.html?id=bc125c8b5ccf4110b538db1188731690. If I am
interpreting the output correctly,the DWR Modeling an Assessment Branch may have discharge restrictions related to
(1) fecal coliform, (2) low dissolved oxygen, and (3)turbidity. I do not believe our proposed discharge would be
restricted based upon the aforementioned parameters.
Please let me know if impending TMDLs may have wastewater discharge restrictions with respect to the proposed
discharge.

APPENDIX I
PRESENT VALUE OF COSTS ANALYSIS

Present-Value-of-Costs Analysis
Discharge to existing tributary to Irwin Creek(Zero 7Q10 flow)
Capital Costs
o Land acquisition costs $NA
o Equipment costs $30,000
o Labor costs $Included with installation costs
o Installation costs $10,000
o Design costs $ 3,000
Co = $43,000
Recurring Annual Costs
o Operation and maintenance costs (with replacement costs) $10,000
o Laboratory costs assuming a weekly monitoring regime for
discharge systems $ 5,000
o Operator and support staff costs $20,000
o Residual disposal costs (included in operation and maintenance costs) $ 0
o Connection and subsequent user fees $ 0
o Permit and compliance fees (included in operation and maintenance costs) $ 0
o Utility costs (power, water, etc.) $ 6,000
Ct = $41,000
Present Value of Costs Calculation
Present value standard formula:
n Ct
PV = Co+
t=t (1+ r)1
Where:
PV = Present value of costs.
Co= Costs incurred in the present year.
C1= Costs incurred in time 1.
t=Time period after the present year(The present year is t=0)
n = Ending year of the life of the facility.
r= Discount rate. For these calculations, the applicant shall use an interest rate quoted by the
lending institution. The loan interest rate quote shall be provided with this analysis.
However, if costs are the same in every time period from year one through year n (i.e., Ct= C, a
constant for t= 1,2,..., n), then the formula reduces to:
PV = Co+ Ct E (1 + r)"- 1
r(1 + r)"
Co = $43,000
Ci = $32,730
r = 4.875 % (Rate provide by Bing Bai of NCDEQ on August 6, 2018)
n = 20 years
PV=$68,175 (assuming equal yearly costs)
