Re: Site Check Report Addendum
Speedway No. 7956
107 South Wilson Street
Fremont, Wayne County, North Carolina
NCDEQ Facility ID No. 0-035993

Dear Ms. Edwards:

Please find attached the Site Check Report Addendum as requested in the North Carolina
Department of Environmental Quality (NCDEQ) correspondence, dated July 13, 2018. Our
environmental consultant, ATC Associates of North Carolina, P.C. (ATC), completed these
activities as a result of the August 18, 2017, Site Check Report, that reported soil concentrations
of xylenes, naphthalene, and C5-C8 Aliphatics greater than their respective Soil-to-Groundwater
Maximum Contaminant Concentrations (MSCC) in boring SB-01. This boring was installed near
the spill bucket end of the premium unleaded tank due to its spill bucket failing its hydrostatic
test on June 8, 2017.

Upon request from the NCDEQ, ATC oversaw ARM Environmental (ARM) install an additional
boring, identified as SB-02, adjacent to the boring SB-01, in order to collect a groundwater
sample. The location of borings SB-01 and SB-02 is provided in Figure 2. Prior to breaking
ground, the area was investigated for potential underground utilities and then cleared using a
soft-dig (air knife) technology to a depth of six feet bls. After clearing the well location, ARM
installed boring SB-02 using direct push technology to a depth of 15 feet below land surface
(bls). A temporary well was constructed of one-inch diameter schedule-40 polyvinyl chloride
(PVC) riser with 10 feet of 0.010-inch slotted screen. The borehole annulus was backfilled with
No. 2 sand filter pack. The well casing and screen were removed from the ground once the
groundwater samples were obtained.

Using a water level indicator, ATC measured the depth to groundwater to be 6.09 feet bls in boring
SB-02. Subsequently, a groundwater sample was collected from the boring; placed in laboratory-
supplied, preserved containers; entered into chain-of-custody; placed on ice; and shipped via
FedEx to ESC Lab Sciences (ESC) [12065 Lebanon Road, Mt. Juliet, Tennessee 37122, North

analysis of volatile organics by EPA Method 6200B, MADEP VPH, Lead by Method 6010B and
low level ethylene dibromide (EDB) by EPA Method 501.4. Laboratory analytical results
detected concentration of benzene, ethylbenzene, total xylenes, naphthalene, lead, and C5-C8
and C9-C12 Aliphatics greater than their respective 2L Groundwater Standards; however, no
analytes were detected greater than their respective gross contaminant levels (GCLs).
Groundwater analytical results are summarized in Table 2, and the groundwater analytical report
is located in Appendix A.

As a result of groundwater concentrations existing greater than their respective 2L Standards, it
is anticipated that a Limited Site Assessment will be required by the NCDEQ to confirm these
groundwater concentrations and determine groundwater receptors. If you have any questions
or require additional information, please contact me at 937-863-6507 or by email at
[e-mail].

Sincerely,

Facility ID No. 0-035993

Dear Ms. Edwards:

On behalf of Speedway LLC (Speedway), ATC Associates of North Carolina, P.C. (ATC) has
completed a Site Check Report Addendum for the above-referenced facility in response to the
North Carolina Department of Environmental Quality (NCDEQ) request, dated July 13, 2018, for
further information after its review of the Site Check Report, dated August 18, 2017. The Site
Check Report was completed following a spill bucket test failure in accordance with the United
States Environmental Protection Agency (EPA) “Revising Underground Storage Tank
Regulations” dated July 15, 2015.

On June 9, 2017, Speedway LLC (Speedway) submitted NCDEQ Form UST-17A, which
documented a suspected release at the above referenced site due to the premium unleaded
spill bucket failing its hydrostatic test on June 8, 2017. On July 7, 2017, Speedway submitted
NCDEQ Form UST-17B that included the failed hydrostatic test results. On July 20, 2017, the
spill bucket was replaced by TideLand Construction & Petroleum.

On July 24, 2017, ATC Associates of North Carolina, P.C. (ATC), used a hand auger to
complete a soil boring (identified as SB-01) to 13 feet below land surface (bls) near the spill
bucket end of the premium unleaded tank. The soil sample was placed in laboratory-supplied
containers, entered into chain-of-custody control, placed on ice, and shipped via FedEx to ESC
Lab Sciences (ESC) [12065 Lebanon Road, Mt. Juliet, Tennessee 37122, North Carolina
Laboratory Certification Number ENV375/DW21704/BI0041, [phone]] for benzene,
toluene, ethylbenzene, total xylenes (BTEX), methyl tert-butyl ether (MTBE), and naphthalene
analysis by Environmental Protection Agency (EPA) Method 6200B, and Massachusetts
Department of Environmental Protection (MADEP) Method for volatile petroleum hydrocarbons
(VPH). Laboratory analytical results detected concentrations of xylenes, naphthalene, and C5-
C8 Aliphatics greater than their respective Soil-to-Groundwater Maximum Contaminant
Concentrations (MSCC). The soil sample analytical results from the original site check activities
are provided in Table 1.

Speedway submitted the Site Check and the Form UST-61 to the NCDEQ on August 18, 2017.
On July 13, 2018, the NCDEQ requested additional information be gathered regarding the site
groundwater and be presented in a Site Check Report Addendum.

Groundwater Sample Collection

On August 6, 2018, ATC oversaw ARM Environmental (ARM) install an additional soil boring,
identified as SB-02, adjacent to boring SB-01 for groundwater sample collection purposes. The
location of soil borings SB-01 and SB-02 are provided in Figure 2. Prior to breaking ground, the
area was investigated for potential underground utilities and then cleared using a soft-dig (air
knife) technology to a depth of six feet bls. After clearing the well location, ARM installed soil
boring SB-02 using direct push technology to a depth of 15 feet bls. A temporary well was
constructed of one-inch diameter schedule-40 polyvinyl chloride (PVC) riser with 10 feet of
0.010-inch slotted screen. The borehole annulus was backfilled with No. 2 sand filter pack. The
well casing and screen were removed from the ground once the groundwater samples were
obtained.

Using a water level indicator, ATC measured the depth to groundwater to be 6.09 feet bls in boring
SB-02. Subsequently, a groundwater sample was collected from the boring; placed in laboratory-
supplied, preserved containers; entered into chain-of-custody; placed on ice; and shipped via
FedEx to ESC Lab Sciences (ESC) [12065 Lebanon Road, Mt. Juliet, Tennessee 37122, North

ONE LAB. NATIONWIDE.CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

ONE LAB. NATIONWIDE.GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Abbreviations and Definitions
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
The remainder of this page intentionally left blank, there are no qualifiers applied to this SDG.
