Dear Mr. Brown:

AECOM Technical Services, Inc. of North Carolina (AECOM) on behalf of Speedway, LLC
(Speedway) is presenting this Site Check Report for the above referenced store (Figure 1). On
January 3, 2023, fuel was discovered in the submersible turbine pump (STP) for the 15,000-gallon
regular unleaded (RUL) gasoline UST and failed hydrostatic testing on January 6, 2023. UST-17A
Form & UST-17B Form were filed with the North Carolina Department of Environmental Quality
(NCDEQ) on January 4, 2023, and January 6, 2023, and are included as Attachment A. To
determine if a release may have occurred to the environment, assessment activities were
conducted as documented in this report. A soil boring log has been included as Attachment B,
and the laboratory report for the soil sample taken during the site check has been included as
Attachment C.

There are no active or historical release incidents associated with the Site.

SITE ACTIVITIES

Soil Sampling

On May 18, 2023, AECOM met with Sweetwater Utility Exploration (Sweetwater) at the site to
collect soil sample (SB-1 (RUL) 3’) from near the STP for the 15,000-gallon RUL UST (Figure 2).
Sweetwater air knifed the soil boring to a depth of approximately 3 feet below ground surface (bgs),
then AECOM used a hand auger to collect the soil sample. The soil sample was collected at
approximately 3 feet bgs and screened with a photoionization detector (PID). A soil boring log is
included as Attachment B. AECOM bottled the sample for laboratory analysis for total petroleum
hydrocarbons for gasoline range organics (TPH-GRO). The sample was submitted to Pace
Analytical Services in Huntersville, North Carolina for analysis at the Huntersville, North Carolina
laboratory.

Site Check Report June 2023
Speedway 6991 Page 2
Roseboro, North Carolina

RESULTS

Based on laboratory analysis, a detectable concentration of TPH-GRO was not reported in the soil
sample SB-1 (RUL) 3’. The laboratory report is included in Attachment C.

CONCLUSIONS AND RECOMMENDATIONS

Based on this information, a release at the site does not appear to have occurred. AECOM, on
behalf of Speedway recommends that this potential release receive a no further action (NFA).

If you have any questions, please call Nicole Long, AECOM Project Manager, at [phone].

UST-17A FORM & UST-17B FORM
UST-17B UST Suspected Release 7 Day Notice
 This form must be used to report to DEQ, within 7 days of discovery, the investigation results for a Suspected Release from any of the following:
a) Failed or inconclusive leak detection or tightness test results. This includes positive test results, such as “Increase”, which indicates the level in the
UST system has increased more than 0.2 gph.
b) Unusual operating conditions which can include, but are not limited to, the erratic behavior of dispensing equipment; the unexplained presence of
water in the tank; the presence of fuel in containment sumps or interstitial spaces; or the degradation of any equipment or element of an underground
storage tank system to the point where that equipment or element can not reasonably be expected to perform its intended function.
c) Internal inspection results such as, perforations, corrosion holes, weld failures, or other similar defects that indicate a release could have occurred.
 If you have more than four UST systems to report suspected release investigations, then attach additional sheets of the UST-17B form.
 Please submit this form along with the supporting documentation to:

1 Conduct a tank and/or line tightness test and attach the results, along with all of the supporting data sheets for the test method, to this form for submittal.
The summary page listing the results by itself is not acceptable. If the tightness test results are fail, then you must repair or replace your UST system and
conduct a site check in accordance with 15A NCAC 2N .0603.
2 Provide sales receipts or other comparable documentation that shows fuel was being dispensed from the UST during the test.
3 Provide invoices (with a description of the work completed) or other documentation that shows the equipment has been repaired.
4 Correct your leak detection results using the correct tank chart and submit copies with this form.
5 Repair the UST in accordance with the manufacturer’s instructions or a national standard (e.g., PEI API 1631) and conduct a site check in accordance with
15A NCAC 2N .0603. If the UST is not repaired, then it must be permanently closed in accordance with the latest version of the UST Sections Guidelines
for Tank Closure.
6 Correct your leak detection results using the amount your meter was adjusted following calibration and submit copies of the meter calibration and leak
detection results with this form.
7 Conduct a tightness test (e.g., hydrostatic test) of the sump and submit the test result along with this form. If the test results are fail, then you must repair
or replace the containment sump and conduct a site check in accordance with 15A NCAC 2N .0603.
8 Submit documentation from your UST equipment contractor explaining how they determined the UST was tilted. Correct your leak detection results using a
tank chart adjusted for the tilt and submit with this form.
Note: Tank, piping, spill bucket and containment sump replacements must be done in accordance with 15A NCAC 2N .0900

SPEEDWAY 6991/60702558
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.
