B. Site History

1. Provide UST Owner and Operator Information

See Table 1.

2. Provide UST Information

See Table 2.

3. Provide Non-UST Information

No ASTs or surface spills are known to exist at the site.

4. Describe relation of location of current UST system to historical UST releases.

According to a 24-Hour Release and UST Leak Reporting Form, there was a line pressure drop
on the regular gasoline product line. A leak was found under multi-product dispenser (MPD)
¾. The North Carolina Department of Environmental Quality (NCDEQ) issued a Notice of
Violation (NOV) on October 5, 2005, for the line pressure drop. The leak was repaired, and
Circle K contracted with Petroleum Service & Calibration (PS&C) to perform tank and line
tightness tests on the UST system. The results of the October 17, 2005, line testing indicated
that the UST system was tight. To fulfill the NCDEQ requirements, ATC performed a site
check. The site check included advancing five soil borings int eh vicinity of MPD ¾. Based
on the soil analytical results, the NCDEQ requested a Phase I Limited Site Assessment (LSA).
A Phase I LSA was submitted to the NCDEQ on February 23, 2007. This release was issued
UST incident number 26955.

On May 31, 2018, Circle K contracted with PS&C to hydrostatically test the onsite spill
buckets. On this date, PS&C found that the premium gasoline spill bucket failed its hydrostatic
test. On June 6, 2018, Circle K personnel submitted a UST-17A (UST Suspected Release 24
Hour Notice) for the premium spill bucket failure.

On July 17, 2018, ATC personnel performed site check activities. Laboratory analytical results
of a soil sample collected in proximity to the premium spill bucket detected target compound
concentrations above Soil-to-Groundwater (STGW) Maximum Soil Contaminant
Concentrations (MSCCs). On July 25, 2018, a 24-Hour Release and UST Leak Reporting
Form was submitted to the NCDEQ. This release was issued UST incident number 42137.
After the recordation of a Notice of Residual Petroleum (NORP), restricting the use of soil and
groundwater at the site, a Notice of No Further Action (NFA) was issued for this release on
August 5, 2019.

5. Provide a Brief Description of Site Characteristics

The subject property consists of one convenience store building and petroleum fueling
equipment. The subject property and surrounding area are fairly level. The site and adjacent
areas are mainly commercial (shopping centers, restaurants, and a bank). Properties beyond the
site are commercial areas. Public water appears to be supplied to the site and surrounding
Circle K Store #2720438 July 24, 2023
NCDEQ Facility ID #0-0000014865 Site Check Report

property. Water supply wells were not identified at the site or adjacent properties. The nearest
surface water feature is an intermittent stream approximately 100 feet southwest of the site. A
retention pond associated with the adjacent shopping center is located approximately 265 feet
southwest of the site and Buffalo Creek is approximately 860 feet west of the site. A
topographic map and site map are attached as Figures 1 and 2, respectively.

C. Site Check Procedures

1. UST System Testing
On June 29, 2023, while Guardian was onsite installing under dispenser containment (UDC)
sumps and shear valve replacements, petroleum-related impacts were noted to soil under the
four dispensers. This soil was stockpiled, on plastic, for off-site disposal. On this date, ATC
submitted a UST-17A: UST Suspected Release 24 Hour Notice. A copy of the referenced
notification is provided in Attachment I.

Upon receipt of the soil laboratory analytical data, on July 19, 2023, ATC submitted a UST-61:
24-Hour Release and UST Leak Reporting Form to the NCDEQ.

2. Site Check Procedure
On June 30, 2023, ATC personnel collected a soil sample, by hand, from directly under each
dispenser. The soil samples were labelled D-1 through D-4. A representative soil sample was
also collected from the stockpiled soil for disposal purposes (sample ID Stock-1). The
approximate locations of the soil samples collected from under the dispensers are provided on
Figure 2.

3. Soil Excavation Activities
Approximately 31.62 tons of petroleum-impacted soil was removed from under the four
dispensers during the construction work. A copy of the disposal manifests is provided in
Attachment II.

D. Site Investigation

1. Field Screening
Field screening was not performed on the soil samples.

2. Soil Sampling Information
On June 30, 2023, ATC personnel collected a soil sample, by hand, from directly under each
dispenser. The soil sample was labelled D-1 through D-4 and were collected at an approximate
depth of four feet below ground surface (bgs). The soil encountered at the sampling depth
consisted mainly of dark reddish-brown gravel and clay.

The soil samples were shipped to a N.C. certified laboratory in a chilled cooler following
proper chain-of-custody procedures. The soil sample was requested to be analyzed by
TPH-Gasoline Range Organics (GRO), TPH-Diesel Range Organics (DRO), and
Environmental Protection Agency (EPA) Method 8260. The stockpile soil sample was
analyzed by TPH-GRO and TPH-DRO only.

NCDEQ Facility ID #0-0000014865 Site Check Report

3. Groundwater and Surface Sampling Information
Groundwater and surface water samples were not collected during site check activities.

4. Quality Control Measures
The soil samples were placed in laboratory provided jars and vials. The samples were
immediately placed on ice and contained in a cooler during transportation. The samples were
transported by courier under a chain-of-custody to the laboratory for analyses.

5. Investigation Results
Laboratory analytical results of the soil samples collected from directly under dispensers 3/4,
5/6, and 7/8 detected target compound concentrations above established State Action Levels
and/or above Soil-to-Groundwater (STGW) Maximum Soil Contaminant Concentrations
(MSCCs). Laboratory analytical results are provided on Table 3. Petroleum-related impacts to
soil are depicted on Figure 3. A copy of the laboratory report and chain-of-custody documents
are provided in Attachment III.

E. Conclusion and Recommendations
Laboratory analytical results of the soil samples collected from directly under dispensers 3/4,
5/6, and 7/8 detected target compound concentrations above established State Action Levels
and/or above STGW-MSCCs. Based on available information, it appears a release has occurred
at the site under dispensers 3/4, 5/6, and 7/8.

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
