6325 West Marshville Boulevard, NPpEs
Marshville, North Carolina N'OEQIpWRI
Dear Mr. Pitner,
AECOM Technical Services of North Carolina, Inc. (AECOM), on behalf of Speedway, LLC (Speedway), is
submitting this Application for Coverage Under General Permit NCG510000 for the Speedway Store No.
7997 (Site), located at 6325 West Marshville Boulevard, Marshville, North Carolina. The Site is operated
by Speedway as a petroleum retail facility and convenience store.
Speedway is proposing underground storage tank (UST) system replacement activities at the Site.
Historically, groundwater depth has ranged from approximately 7 to 10 feet below ground surface (bgs)
near the UST basin. Therefore, dewatering from the tank basin is anticipated. AECOM expects to
discharge treated groundwater for approximately two weeks at an estimated flow of 20 to 170 gallons per
minute (gpm) depending on the recharge rate of groundwater in the excavation. 170 gpm assumes worst
case scenario and use of two pumps but will most likely be one pump working intermittently. AECOM
proposes to pump groundwater to a 21,000-gallon frac tank and then treat it via 2,000-pound carbon
vessels prior to discharge. Breakthrough calculations assume worst case scenario for flow and level of
impacts. The treated groundwater would be discharged via aboveground piping to the Buck Branch (class
C surface water) located approximately 235 feet west of the Site.
AECOM sampled monitoring well MW-19, located downgradient of the tank field, on June 30, 2023 and
analyzed for volatile organic compounds (VOCs) via standard Method (SM) 6200B, lead and total
hardness via EPA Method 602013, total suspended solids (TSS) via SM2540D-2015, pH via SM4500-H+B-
2011, and total recoverable phenolics via EPA 420.4 Rev 1.0 1993. Carbon breakthrough was calculated
using the current laboratory analytical data.
If there are any questions or concerns regarding this report, please contact Nathan Pinsker at
[phone].
Yours sincerely,
Nathan Pinsker

QUALIFIERS
Project: Speedway 7997 Marshville
Pace Project No.: 92675415
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.
Pace Analytical Services, LLC
9800 Kincey Ave. Suite 100
Huntersville, NC 28078
[phone]
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 SWB46 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
'Total' may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI - The NELAC Institute.
ANALYTE QUALIFIERS
H3 Sample was received or analysis requested beyond the recognized method holding time.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.

Subject Carbon Breakthrough Calculation Approved by Brett G. Schaefer, PE
OBJECTIVE
Determine the time it will take for breakthrough to occur in granular activated carbon (GAC) vessels used for treating groundwater with
concentrations of dissolved petroleum hydrocarbons.
GIVEN/ REFERENCES
NPDES General Permit NCG510000
United States Army Corps of Engineers (USACE) Adsorption Design Guide (DG 1110-1-2), March 1, 2001
CALCULATIONS
Using the following design basis, calculate the carbon consumption rate (lb/day) and the time for breakthrough to occur.
Inout data: Basis:
Two GAC vessels in parallel. Calculation applies to each vessel. Contractor -supplied process flow diagram
Influent flow rate (per vessel) = 90 gallons per minute (gpm) Contractor -supplied process flow diagram
On -Line Factor = 100 % Continuous operation during dewatering activities
Surface loading rate = 2-10 gpm/ ft2 Recommended
Empty Bed Contact Time
(EBCT) _ >7 minutes Recommended:
Inlet concentrations = see C-in, Table 1 below. Maximum concentrations from groundwater monitoring data. See Table 1-
Component Name to see what well exhibits the highest COC concentration.
Outlet concentrations = see C-out, Table 1 below. Effluent limitations (average monthly) from NCAC 2L Standards
Adsorptive capacity = see carbon adsorptive capacity in Table 1 below. Calculated
Calculate mass of solute adsorbed per mass of adsorbent using Fruendlich Isotherm Equation (from USACE DG 1110-1-2, p. 2-5):
where
x 1 x = amount of solute adsorbed (µg, mg, or g)
- = KC* m = mass of adsorbent (mg or g)
m C = conc. of solute remaining in solution after adsorption is complete (at equilibrium) (mg/L)
K, n = constants that must be determined for each solute, carbon type, and temperature.

Pace Project No.: 92675483
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.

9800 Kincey Ave. Suite 100
Huntersville, NC 28078

PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
'Total' may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI - The NELAC Institute.
ANALYTE QUALIFIERS
C9 Common Laboratory Contaminant.
L1 Analyte recovery in the laboratory control sample (LCS) was above QC limits. Results for this analyte in associated
samples may be biased high.
MO Matrix spike recovery and/or matrix spike duplicate recovery was outside laboratory control limits.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
R1 RPD value was outside control limits.
