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.
November 9, 2018
Site Check Report
During UST closure activities by Texaco, conducted in October 1989, a release from the UST
system was discovered and reported to the North Carolina Department of Environmental
Quality (NCDEQ). The release was issued UST incident #5371. The incident was issued a
Notice of No Further Action (NFA).
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 is fairly level. The subject property is
located in a residential and light commercial area of Chapel Hill. Public water is supplied to
the area. The presence of water supply wells in the immediate vicinity of the site was not
noted. A topographic map and site map are attached as Figures I and 2, respectively.
C. Site Check Procedures
1. UST System Testing
On September 19, 2018, during onsite testing of the UST system, it was determined that the
regular unleaded #1, regular unleaded #2, premium, and diesel spill buckets would not pass
their respective hydrostatic tests. On September 26, 2018, Circle K personnel submitted a
UST-17A UST Suspected Release 24 Hour Notice. On November 9, 2018, upon receipt of the
soil analytical results, ATC personnel submitted a UST-61 24-Hour Release and UST Leak
Reporting Form to NCDEQ Raleigh Regional Office. As of the date of this report, Circle K is
in the process of getting the spill bucket repaired/replaced.
Copies of the referenced notifications are provided in Attachment I.
2. Site Check Procedure
On October 23, 2018, ATC personnel contracted with Sweetwater Utility to air knife the
boreholes for future soil samples SS-1, SS-2, SS-3, and SS-4 to six feet below ground surface
(bgs). On October 29, 2018, ATC and Regional Probing Services (RPS) personnel met onsite
and collected soil samples from SS-1 (premium spill bucket), SS-2 (diesel spill bucket), SS-3

Circle K Store #2723102
NCDEQ Facility ID #00-0-0000020451
November 9, 2018
Site Check Report
(regular #2 spill bucket), and SS-4 (regular #1 spill bucket) at a depth of approximately thirteen
feet bgs. The soil samples were then submitted for laboratory analyses. The locations of the
soil samples are provided on Figure 2.
It should be noted the soil samples were collected as close as possible to the noted spill buckets.
3. Soil Excavation Activities
Soil excavation was not performed as part of this site check.
D. Site Investigation
1. Field Screening
Soil samples SS-1, SS-2, SS-3, and SS-4 were screened with a photoionization detector (PID)
following sample collection. The respective PID readings are provided on Table 3.
2. Soil Sampling Information
Soil samples SS-1, SS-2, SS-3, and SS-4 were collected at approximately 13 feet bgs on
October 29, 2018. The soil encountered at the sampling depth consisted of grayish -brown silty
clay. Boring logs for SS-1, SS-2, SS-3, and SS-4 are provided in Attachment II.
The soil samples were shipped to a N.C. certified laboratory in a chilled cooler following
proper chain -of -custody procedures. Soil samples SS-1, SS-3, and SS-4 were requested to be
analyzed by Total Petroleum Hydrocarbons (TPH)-Gasoline Range Organics (GRO) and
Environmental Protection Agency (EPA) Method for 8260B. Soil sample SS-2 was requested
to be analyzed by TPH-GRO and TPH-diesel range organics (DRO).
3. Groundwater and Surface Sampling Information
Groundwater samples and surface water samples were not collected.
4. Quality Control Measures
The soil samples were placed in laboratory provided jars and vials. Samples were immediately
placed on ice and contained in a cooler during transportation. Samples were transported by
courier under a chain -of -custody to the laboratory for analysis.
5. Investigation Results
TPH-GRO or TPH-DRO concentrations were not detected above applicable State Action
Levels in any of the soil samples. Laboratory analytical results of soil sample SS-4 (regular #1
spill bucket) detected benzene and methyl tert butyl ether (MTBE) concentrations above the
established Soil -to -Groundwater (STGW) Maximum Contaminant Concentrations (MSCCs).
Other target compound concentrations were detected above laboratory method detection limits
but below STGW-MSCCs. The results are shown in 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 soil sample SS-4 (regular #1 spill bucket) detected benzene and
MTBE concentrations above the established STGW-MSCCs. Other target compound
concentrations were detected above laboratory method detection limits but below

Circle K Store #2723102
NCDEQ Facility ID #00-0-0000020451
November 9, 2018
Site Check Report
STGW-MSCCs. TPH-GRO or TPH-DRO concentrations were not detected above applicable
State Action Levels in any of the soil samples.
Based on the soil analytical data, it appears a release of petroleum has occurred from the regular
unleaded #1 spill bucket.

➢ This form must be used to report to DEQ, within 24 hours of discovery, 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 releases, then attach additional sheets of the UST-17A form. You only
need to list the UST systems at your site that have suspected releases.
➢ Within 7 days of discovery, submit a UST-17B form to document the response activities taken to investigate the suspected release.
➢ Please submit this form to: NCDEQ/DWM, UST Section

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 till
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
