Wells Fargo Tryon Street GWR-NPDES Permit NC0088226 NCDEQ/DWR/NPDES
500 Block of South Tryon Street
Charlotte, Mecklenburg County, North Carolina
ECS Project 49-1234-E
Dear Mr.Thedford:
ECS Southeast, LLP (ECS), on behalf of Childress Klein Properties and Wells Fargo, N.A., is requesting
approval for renewal of the existing system that is currently operating and has National Pollutant
Discharge Effluent System (NPDES) permit NC0088226. The permit includes the capture of site rain
water and de-watering groundwater from the site subgrade parking garage but also de-watering
groundwater from the adjacent subgrade parking garage at "The Green at Wachovia". Additionally, the
captured water is routed through an on-site water treatment system designed by Aquapura, Inc. that
utilizes the water for on-site needs such as in cooling towers thereby lowering the amount of municipal
water required. The attached renewal has been signed by Mr. John Cranfill of Childress Klein an
authorized signee for the permit.
BACKGROUND INFORMATION
The subject site is the Wells Fargo Tryon Street GWR (WFTS-GWR) which includes the tower and
subgrade parking deck at 550 South Tryon Street, located at the 500 block of South Tryon Street in
Charlotte, Mecklenburg County, North Carolina. The WFTS-GWR site is bound by Church Street to
the northwest, Levine Avenue of the Arts to the northeast, Stonewall Street to the southwest and
South Tyron Street. Currently, the site is operating NPDES permit No. NC0088226 and discharging
groundwater to a storm sewer located in South Tryon Street. The storm sewer ultimately discharges to
Little Sugar Creek, a Class C surface water in the Catawba River Basin. Figures 1 and 2 indicate the
location of this site and outfall location. No sludge waste is generated as part of the treatment process.
Filters are replaced as needed and properly disposed of off-site.
Permit Sampling
In accordance with the existing NPDES permit, the system includes treatment of the water prior to
discharge, via the Aquapura system. The permit also requires that the discharge be monitored,
sampled, and reported. Additionally, a monthly discharge monitoring report (DMR) is required to be
submitted to the NCDEQ, DWQ. The DMR requires the monthly monitoring, including the collection of
grab effluent samples for laboratory analysis, and reporting. Once per quarter, additional grab samples
of the effluent are required to be collected and submitted for laboratory analysis for chronic toxicity
with results submitted to the NCDEQ. ECS does not recommend changes to the scheduled sampling. A
copy of the most recent post treatment data (from November 2019) collected prior to discharge in
accordance with the current permit and reporting is included as an attachment to this application.

QUALIFIERS
Project: Wells Fargo Monthly
Pace Project No.: 92454537
DEFINITIONS
DF-Dilution Factor,if reported,represents the factor applied to the reported data due to dilution of the sample aliquot.
ND-Not Detected at or above adjusted reporting limit.
TNTC-Too Numerous To Count
J-Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL-Adjusted Method Detection Limit.
PQL-Practical Quantitation Limit.
RL-Reporting Limit-The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S-Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270.The result for each analyte is
a combined concentration.
Consistent with EPA guidelines,unrounded data are displayed and have been used to calculate%recovery and RPD values.
LCS(D)-Laboratory Control Sample(Duplicate)
MS(D)-Matrix Spike(Duplicate)
DUP-Sample Duplicate
RPD-Relative Percent Difference
NC-Not Calculable.
SG-Silica Gel-Clean-Up
U-Indicates the compound was analyzed for,but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Pace Analytical is TNI accredited.Contact your Pace PM for the current list of accredited analytes.
TNI-The NELAC Institute.
LABORATORIES
PAST-A Pace Analytical Services-Asheville
PAST-C Pace Analytical Services-Charlotte
ANALYTE QUALIFIERS
D6 The precision between the sample and sample duplicate exceeded laboratory control limits.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample(LCS)recovery.
v2 The continuing calibration verification was below the method acceptance limit.The analyte was not detected in the
associated samples and the sensitivity of the instrument was verified with a reporting limit check standard.
v3 The continuing calibration verification was below the method acceptance limit.Any detection for the analyte in the
associated samples may have low bias.
