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

A diesel-exhaust fluid (DEF) AST is located at the subject facility.

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

Various releases have been reported at the property as follows:
• UST Incident No. 44346 – diesel product line failure at submersible turbine pump
(STP) for the 8,000-gallon auto-diesel UST (June 20, 2014).
• UST Incident No. 44556 – diesel product line closure at truck canopy – issued Notice of
No Further Action (NFA).
• UST Incident No. 47300 – diesel tank #7 overfill (October 7, 2020) – issued a Notice of
NFA.
• UST Incident No. 47682 – diesel tank #7 overfill (March 29, 2021) – issued a Notice of
NFA.

Information regarding the various releases is presented in reports on file at the NCDEQ.

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 area mainly
consists of commercial businesses and residential areas. Based on information gathered during
previous assessment activities, ATC personnel learned that the City of Greensboro provides
public water to properties along Sandy Ridge Road to the north of Interstate 40/Highway 42
and to properties south of 2914 Sandy Ridge Road (the Piedmont-Triade Farmers Market).
According to the City of High Point, public water is provided to the subject facility only. It
appears neither municipality provides water to Norcross Road (except the subject facility),
Endicott Road, Lakedale Road, or Sandy Ridge Road between the subject property and 2914
Sandy Ridge Road. ATC identified at least twenty-seven (27) water supply wells within 1,500 feet
of the source area. The closest water supply wells were identified approximately 489 feet west at 8414
Norcross Road (WSW-1) and at approximately 565 feet east at 3016 Sandy Ridge Road (WSW-9). A
water meter was not noted on either of these properties; therefore, it is assumed these wells are used for
potable purposes. The nearest surface water body is an unnamed tributary to the West Fork Deep River,
located approximately 1,200 feet southwest of the source area. An unnamed tributary to the East Fork
Deep River, located approximately 1,700 feet east of the source area. A topographic map and site
map are attached as Figures 1 and 2, respectively.
C. Site Check Procedures
Circle K Store #2701526 April 22, 2024
NCDEQ Facility ID #00-0-0000001979 Site Check Report

1. UST System Testing
On February 28, 2024, during annual testing, it was found that the tank #2 gasoline spill bucket
failed its hydrostatic test. The spill bucket was subsequently replaced and retested. On April 2,
2024, the new spill bucket was tested and found to pass its hydrostatic test. A copy of the
testing results is provided in Attachment I.

Upon receipt of the laboratory analytical data, on April 22, 2024, ATC prepared and submitted
a UST-61: 24-Hour Release and UST Leak Reporting Form. A copy of the notification is
provided in Attachment II.

2. Site Check Procedure
On April 1, 2024, ATC personnel collected a soil sample, by hand, from directly under the
removed tank #2 gasoline spill bucket. The soil sample collected from the location of the
gasoline spill bucket was labelled SS-1. The location of the soil sample is provided on Figure
2.

3. Soil Excavation Activities
Soil excavation was not performed as part of this site check.

D. Site Investigation

1. Field Screening
The soil sample was collected at an approximate depth of two and one-half feet below ground
surface (bgs). Upon collection, the soil sample was screened with a photoionization detector
(PID). The respective PID reading is provided on Table 3.

2. Soil Sampling Information
On April 1, 2024, ATC personnel collected a soil sample, by hand, from directly under the
removed tank #2 gasoline spill bucket. The soil sample collected from the location of the
gasoline spill bucket was labelled SS-1. The location of the soil sample is provided on Figure
2.

The soil encountered at the sampling depth consisted of clayey silt with fine to medium-grained
sand. It should be noted the soil was noted to be moist and have a strong petroleum odor.

The soil sample was 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 Total Petroleum
Hydrocarbon (TPH)-Gasoline Range Organics (GRO) and Environmental Protection Agency
(EPA) Method 8260B.

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

4. Quality Control Measures
The soil sample was placed in laboratory provided jars and vials. The sample was immediately
placed on ice and contained in a cooler during transportation. The sample was transported by
courier under a chain-of-custody to the laboratory for analyses.
Circle K Store #2701526 April 22, 2024
NCDEQ Facility ID #00-0-0000001979 Site Check Report

5. Investigation Results
Laboratory analytical results of the soil sample collected under the removed tank #2 gasoline
spill bucket detected several target compound concentrations above established standards. It
should be noted the detected naphthalene concentration was detected above its established
Residential Maximum Soil Contaminant Concentration (MSCC). Laboratory analytical results
are provided on Table 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 sample collected under the removed tank #2 gasoline
spill bucket detected several target compound concentrations above established standards. It
should be noted the detected naphthalene concentration was detected above its established
Residential MSCC. Based on available information, it appears a release has occurred from the
tank #2 gasoline spill bucket.

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
