Executive Summary
As required by the North Carolina Department of Environmental Quality (NCDEQ), AECOM prepared this
Underground Storage Tank Removal and Initial Abatement Action Report on behalf of Speedway, LLC (Speedway) for
Speedway No. 7940 (Site), located at 5729 West Friendly Avenue, Guilford College, Guilford County, North Carolina.
Currently a single-story convenience store exists on-site where Speedway operates a petroleum dispensing system
associated with retail fuel sales. Five underground storage tanks (USTs) were removed from the site. The removed
UST system was replaced with one 12,000-gallon PUL gasoline UST, one 12,000-gallon RUL gasoline UST and one
12,000-gallon compartment tank which consisted of one 8,000-gallon compartment for diesel, and one 4,000-gallon
compartment for kerosene.
The site contained five steel single-walled lined underground storage tanks (USTs): two 8,000-gallon tanks containing
regular unleaded (RUL) gasoline (UST #1 and UST #2), one 8,000-gallon tank containing premium unleaded (PUL)
gasoline (UST #3), one 8,000-gallon tank containing kerosene fuel (UST #4), and one 8,000-gallon tank containing
diesel (DSL) (UST#5) which were installed January 1, 1976. Prior to removal activities, the tank compartments were
emptied, washed, and then made inert with dry ice. The USTs were removed from the ground on October 28, 2022.
The USTs were observed to be in good condition. AECOM collected 15 soil samples from under the USTs, seven
from under the dispensers, and eight from under the product lines for analysis of gasoline range organics (TPH-GRO)
and/or TPH diesel range organics (TPH-DRO). Multiple closure samples exceeded the NCDEQ action levels.
Three risk-based soil samples were collected from the bottom of the excavation and two risk-based soil samples were
collected from under the canopy. The risk-based were analyzed for volatile organic compounds (VOCs) and
Massachusetts Department of Environmental Protection (MADEP) volatile petroleum hydrocarbons (VPH). Two
samples of the five samples were also submitted for analysis of semi-volatile organic compounds (SVOCs) and
MADEP extractable petroleum hydrocarbons (EPH). Analytical results indicated that the one or more VOCs were
above Soil to Ground (S-G) Maximum Soil Contaminant Concentrations (MSCCs) in the five soil samples collected
and were above Residential MSCCs in three of the five soil samples [DE-1, D-1, PL-8 (RISK)] collected. One or more
MADEP VPH compounds were above S-G MSCCs in three of the five soil samples collected and Residential MSCCs
in one of the five soil samples (DE-1) collected. Naphthalene and MADEP VPH C9-C10 Aromatic (Unadjusted)
compounds exceeded Industrial Commercial MSCCs in one soil sample (DE-1).
To mitigate soil contamination, AECOM oversaw the removal of 1,167.05 tons of soil from the UST excavation area
and the dispenser island excavation area. The excavation for the new USTs was approximately 40 feet x 35 feet x 15
feet.
The site has one previous release. Incident number 45028 was opened April 12, 2018 following at Site Check of the
RUL UST spill bucket. On April 11, 2022, a Notice of Residual Petroleum (NORP) for restrictions to groundwater and
soil was filed at Guilford County Register of Deeds. On April 11, 2022, a Conditional Notice of No Further Action was
issued by NCDEQ.
Due to the soil samples that exceeded commercial standards at the bottom of the UST excavation, AECOM, on
behalf of Speedway, recommends installing one groundwater monitoring downgradient of the USTs to assess
groundwater.

product lines for analysis of gasoline range organics (TPH-GRO) and/or TPH diesel range organics (TPH-DRO)
during the UST removal in November 2022. Multiple closure samples exceeded the NCDEQ action levels. Upon
receipt of the analytical results of the closure soil samples collected, AECOM reported the release to NCDEQ on
November 15, 2022. The copy of the UST-61 Form (24-Hour Release and UST Leaking Report Form) is included as
Appendix C.
Three risk-based soil samples were collected from the bottom of the excavation and two risk-based soil samples were
collected from under the canopy. The risk-based were analyzed for volatile organic compounds (VOCs) and
Massachusetts Department of Environmental Protection (MADEP) volatile petroleum hydrocarbons (VPH). Two
samples of the five samples were also submitted for analysis of semi-volatile organic compounds (SVOCs) and
MADEP extractable petroleum hydrocarbons (EPH). Analytical results indicated that the one or more VOCs were
above Soil to Ground (S-G) Maximum Soil Contaminant Concentrations (MSCCs) in the five soil samples collected
and were above Residential MSCCs in three of the five soil samples [DE-1, D-1, PL-8 (RISK)] collected. One or more
MADEP VPH compounds were above S-G MSCCs in three of the five soil samples collected and Residential MSCCs
in one of the five soil samples (DE-1) collected. Naphthalene and MADEP VPH C9-C10 Aromatic (Unadjusted)

STATE USE ONLY
I.D. #_____________________
Date Received______________
INSTRUCTIONS (READ THIS FIRST)
Complete and return a UST-3 form at least thirty (30) days prior to closure or change-in-service activities.
Completed UST closure or change-in-service site assessment reports, along with a copy of the UST-2A and/or 2B forms, should be submitted
to the appropriate Division of Waste Management (DWM) Regional Office within thirty (30)days following closure activities. The UST-2 form
should also be submitted to the Central Office in Raleigh so that the status of the tanks may be changed to permanently closed and your
tank fee account can be closed out.Note: Tank fees may be due for unregistered tanks.
UST closure and change-in-service site assessments must be completed in accordance with the latest version of the Guidelines for Site
Checks, Tank Closure and Initial Response. The guidelines can be obtained at https://deq.nc.gov/about/divisions/waste-management/ust.
Note: To close tanks in place you must obtain prior approval from the DWM Regional office located in the region where the facility is located.
You must make sure that USTs removed from your property are disposed of properly. When choosing a closure contractor, ask where the
tank(s) will be taken for disposal. Usually, USTs are cleaned and cut up for scrap metal. This is dangerous work and must be performed
by a qualified company. Tanks disposed of illegally in fields or other dumpsites can leak petroleum products and sludge into the environment.
If your tanks are disposed of improperly, you could be held responsible for the cleanup of any environmental damage that occurs.

Definitions of Sources Tank: means the tank that stores the product and is part of the underground storage tank system Piping: means the piping and connectors running from the tank or submersible turbine pump to the dispenser or other end-use equipment (Vent, vapor recovery, or fill lines are excluded.) Dispenser: includes the dispenser and the equipment used to connect the dispenser to the piping (e.g., a release from a suction pump or from components located above the shear valve) Submersible Turbine Pump (STP) Area includes the submersible turbine pump head (typically located in the tank sump), the line leak detector, and the piping that connects the submersible turbine pump to the tank Delivery Problem: identifies releases that occurred during product delivery to the tank. (Typical causes associated with this source are spills and overfills.)
Other: serves as the option to use when the release source is known but does not fit into one of the preceding categories (e.g., for releases from vent lines, vapor recovery lines, and fill lines) Unknown: identifies releases for which the source has not been determined Definitions of Causes
Spill: use this cause when a spill occurs (e.g., when the delivery hose is disconnected from the tank fill pipe or when the nozzle is removed from the dispenser) Overfill: use when an overfill occurs (e.g., overfills may occur from the fill pipe at the tank or when the nozzle fails to shut off at the dispenser) Physical or Mechanical Damage: use for all types of physical or mechanical damage, except corrosion (e.g., puncture of tank or piping, loose fittings, broken components, and components that have changed dimension) Corrosion: use when a metal tank, piping, or other component has a release due to corrosion (e.g., for steel, corrosion takes the form of rust) Installation Problem: use when the problem is determined to have occurred specifically because the UST system was not installed properly Other: use this option when the cause is known but does not fit into one of the preceding categories (e.g., putting regulated substances into monitoring wells) Unknown: use when the cause has not been determined

QUALIFIERS
Pace Project No.:
Project:
92635127
44682-7940 Guilford College
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.
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
Common Laboratory Contaminant.C9
The precision between the sample and sample duplicate exceeded laboratory control limits.D6
Analyte concentration exceeded the calibration range. The reported result is estimated.E
The recalculated concentration of the calibration standard(s) did not meet method acceptance criteria; this result should
be considered an estimated value.IK
Analyte detected below the reporting limit, therefore result is an estimate. This qualifier is also used for all TICs.J
Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.M1
The lab does not hold NELAC/TNI accreditation for this parameter but other accreditations/certifications may apply. A
complete list of accreditations/certifications is available upon request.N2
Matrix spike recovery was outside laboratory control limits due to a parent sample concentration notably higher than the
spike level.P6
The continuing calibration verification was above the method acceptance limit. Any detection for the analyte in the
associated samples may have a high bias.v1

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.
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.
