1.5 RELEASE INFORMATION
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. In response, the NCDEQ issued a Notice of
Violation (NOV) on October 5, 2005. The leak was repaired, and on October 17, 2005, Circle K contracted with
Petroleum Service & Calibration (PS&C) to perform tank and line tightness tests on the UST systems. The results of the
UST system testing noted all system components tested tight. To fulfill the NCDEQ requirements, ATC performed a site
check in proximity to MPD ¾. Based on the soil analytical results, the NCDEQ requested a Phase I Limited Site
Assessment (LSA). A Phase I LSA Report 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.

On July 17, 2018, ATC personnel performed site check activities. Laboratory analytical results of a soil sample collected
in proximity to the premium gasoline 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.

On June 29, 2023, while Guardian was onsite installing under dispenser containment (UDC) sumps and shear valve
replacements, petroleum-related impacts to soil were noted under the four dispensers. This soil was stockpiled, on plastic,
for off-site disposal.

On June 30, 2023, ATC personnel collected a soil sample, by hand, from directly under each dispenser. A representative
soil sample was also collected from the stockpiled soil for disposal purposes. Approximately 31.62 tons of
petroleum-impacted soil was removed from under the four dispensers during the construction work. Laboratory analytical
results of the soil sample collected from directly under dispenser 3/4, 5/6, and 7/8 detected target compound
concentrations above established State Action Levels and/or above STGW-MSCCs. Upon receipt of the laboratory
analytical results, on July 19, 2023, ATC personnel submitted a UST-61: 24-Hour Release Notice and UST Leak
Reporting Form to the NCDEQ. The NCDEQ issued UST incident number 49121. A Site Check Report was submitted
to the NCDEQ on July 24, 2023.

3.0 RECEPTOR PATHWAY INFORMATION
As defined by NCDEQ, a receptor is “any human, plant, or animal that is or has the potential to be adversely affected by
the release or migration of contaminants”. With respect to the subject facility, the following sections present information
regarding potential receptor pathways for the migration of contaminants and pathway relationships to the facility.

In an effort to efficiently gather complete and accurate data, ATC personnel performed a receptor survey of the area.
Activities included a visual reconnaissance survey within 1,500 feet radial distance of the site, obtaining utility
information from the City of Sanford and obtaining property use information from the Lee County Tax Department. The
results of the survey, regarding the potential identification of water wells located within 1,500 feet of the site, are
summarized below.

3.1 WATER SUPPLY WELLS
According to the City of Sanford Public Works Commission, public water is supplied to the site and the properties within
1,500 feet of the site. Water supply wells were not observed within 1,500 feet of the source area during the visual
reconnaissance survey.

3.2 PUBLIC WATER SUPLIES
Public water supply to the area is provided by the City of Sanford Public Works Commission. It should be noted that it is
not mandatory for properties to be connected to the public water supply.

3.3 SURFACE WATER BODIES
As shown on Figure 1, the nearest identified surface water feature is an unnamed tributary to Big Buffalo Creek located
approximately 150 feet southwest the site. A retention pond associated with the adjacent shopping center is located

3.4 WELLHEAD PROTECTION AREAS
At the time of this investigation, the source area is not located within an approved wellhead protection area as defined in
42 USC 300h-7(e).

3.5 REGIONAL GEOLOGY AND HYDROGEOLOGY
The site is located within the Cape Fear Formation. According to the Geologic Map of North Carolina (Brown, et al.,
1985), the site lies in an area which is characterized by sandstone and sandy mudstone, yellowish grey to bluish grey,
mottled red to yellowish orange, indurated, graded and laterally continuous bedding, blocky clay, faint crossbedding,
feldspar and mica common.

Aquifers in the Coastal Plain are regional in extent, consisting of porous sand and limestone aquifers. The Coastal Plain
sediments have been divided by Winner and Coble (1996) into ten aquifers separated by confining units. The shallow
unconfined aquifer present in most areas is called the surficial aquifer. The confined aquifers include the Peedee, Black
Creek, Upper Cape Fear, Lower Cape Fear, Castle Hayne, Beaufort, Pungo River, and Yorktown aquifers.

Aquifers in the Coastal Plain province occur in gently dipping layers of sediments and sedimentary rock. These aquifers
outcrop at land surface in some updip areas and are buried much deeper in downdip areas (generally to the east and
southeast). In general, depth to groundwater in shallow unconfined aquifers follows topography, being shallower near
streams and deeper on hilltops. However, in the deeper confined aquifers, such as the Black Creek and Upper Cape Fear
aquifers, the water level (potentiometric level) is under pressure and is affected by both local and regional pumping.

ATC reviewed a well log for a well located less than one mile from the site. The well log was obtained from the
Hydrogeologic Framework website maintained by the NCDEQ. The log indicated that the surficial aquifer in the site
vicinity extends to a depth of 105 feet below land surface and the Upper Cape Fear extends form 105 feet to 210 feet
below land surface.

3.6 SUBSURFACE STRUCTURES
Subsurface structures identified at the subject facility include sanitary sewer lines, municipal water lines, and storm
drains. A water meter was observed on-site. Electric service int eh area appears to be pole mounted. Other utilities may
be present.

3.7 LAND USE
The site and adjacent areas are mainly commercial establishments or residential areas. Adjacent property owner
information is provided on Table 1.

4.0 LIMITED SITE ASSESSMENT ACTIVITIES
The limited site assessment activities performed to collect data for this report included researching site-specific, local and
regional data, performing soil and groundwater sampling, and submitting soil and groundwater samples for analytical
testing. Information was also obtained from prior reports prepared by ATC. The following sections discuss specific
methodologies used in conducting these limited site assessment activities.

4.1 MONITORING WELL INSTALLATION
Monitoring wells MW-2 and MW-3 were installed by personnel with AmeriProbe on September 7, 2023, as part of
limited site assessment activities. It should be noted monitoring well MW-1 was installed and properly abandoned as part
of previous site activities. The locations of monitoring wells MW-2 and MW-3 are depicted on Figure 2.

Monitoring wells MW-2 and MW-3 were installed to a depth of 20 feet bgs. The wells were installed using hollow-stem
augers and were constructed of two-inch diameter well casing made of flush-joint, threaded schedule-40 poly vinyl
chloride (PVC) pipe. The PVC well screen is 0.010-inch slot with a screened interval of 15 feet for each monitoring well.
A coarse sand pack (filter pack) was used to backfill the well annulus to a depth of approximately two feet above each
well screen. A one and one-half foot thick bentonite seal was placed above the filter packs, and neat cement was used to
fill the remainder of the well annuli to ground surface.

The wells were installed as flush-mounted and were provided with a sealing and locking cap. A protective, steel,
traffic-bearing cover was placed over each well upon completion. The boring logs and well construction records are
presented in Appendix A.

4.2 SOIL SAMPLING
During the installation of monitoring wells MW-2 and MW-3, a soil sample was collected from each monitoring well
boreholes for submittal to the project laboratory for analyses. The soil sample were collected from each borehole during
monitoring well installation using a field-decontaminated stainless steel hand auger. The soil samples were collected at a
depth of four to five feet bgs for boring SMW-2 and a depth of three to four feet bgs for boring SMW-1. The soil samples
were screened with a photoionization detector (PID). The soil samples were placed directly into laboratory supplied
containers and placed into a chilled cooler. The soil sample was submitted for analysis by Environmental Protection
Agency (EPA) Methods 8260 and 8270 and Massachusetts Department of Environmental Protection (MADEP) methods
for volatile petroleum hydrocarbons (VPH) and extractable petroleum hydrocarbons (EPH).

4.3 GROUNDWATER SAMPLING
On September 13, 2023, groundwater samples were collected from monitoring wells MW-2 and MW-3. The monitoring
wells were purged prior to sampling by removing a minimum of three well volumes of water from each well. After
Phase I Limited Site Assessment Report ATC Associates of North Carolina, P.C.
Circle K Store #2720438 October 5, 2023

allowing sufficient time for recharge, a representative groundwater sample was collected from each well using a new,
disposable Teflon bailer. Upon collection, the groundwater samples were placed into laboratory-approved containers,
packed in ice, and delivered under chain-of-custody to SGS North America (SGS) in Scott, Louisiana for analyses. The
groundwater samples were analyzed by EPA Method 6200B to include ethanol and oxygenates, EPA Method 625 plus ten
highest non-target peaks, EPA Method 504.1 for ethylene dibromide (EDB), EPA Method 6020 for lead, and MADEP
methods for VPH and EPH.

5.0 SITE GEOLOGY AND HYDROGEOLOGY
5.1 DESCRIPTION OF SHALLOW SUBSURFACE GEOLOGY
According to the Web Soil Survey, the predominant site soil is Mayodan fine sandy loam. The parent material of this soil
type is residuum weathered from mudstone and/or shale and siltstone and/or sandstone. Typically, this soil is composed
of fine sandy loam to six inches below grade. From approximately six to nine inches below grade, this soil is typically a
sandy clay loam. A clay layer is expected to be encountered between nine and 33 inches below grade. Sandy clay loam is
present below the clay layer. This soil is well drained with the water table expected at greater than 80 inches below grade.
Available water capacity is moderately high to high.

Soil encountered during the installation of monitoring wells MW-2 and MW-3 generally consisted of clayey silt to 14 feet
bgs. From 14 to 20 feet bgs, the soil consisted of sandy silt. The boring logs for monitoring wells MW-2 and MW-3 are
provided in Appendix A.

5.2 GROUNDWATER OCCURRENCE
On September 13, 2023, ATC collected static water level measurements from monitoring wells MW-2 and MW-3.
Depths to water measurements were collected using an electronic oil/water interface probe. Depths to water
measurements ranged between 6.91 feet bgs in monitoring well MW-2 to 7.62 feet bgs in monitoring well MW-3. Table
2 provides a summary of well construction and depths-to-groundwater measurement.

5.3 GROUNDWATER FLOW DIRECTION
The groundwater depths were converted to relative elevations using an assumed datum of 100 feet relative to an arbitrary
on-site benchmark. Monitoring well construction details and current groundwater elevation data are included in Table 2.
Due to limited data points, a groundwater elevation contour map could not be generated. Based on a review of Figure 1, it
appears groundwater may flow to the southwest.

6.0 ANALYTICAL RESULTS
6.1 SOIL ANALYTICAL RESULTS
Laboratory analytical results of the soil sample collected from the borehole of monitoring well MW-2 at four to five feet
bgs detected a benzene concentration above its established Soil-to-Groundwater (STGW) Maximum Soil Contaminant
Concentration (MSCC). Laboratory analytical results of the soil sample collected from the borehole of monitoring well
MW-3 at three to four feet bgs did not detect target compound concentrations above established STGW-MSCCs. A
summary of soil laboratory analytical results is provided in Table 3. Petroleum-related impacts to soil are provided on
Figure 3. A copy of the laboratory analytical report is included as Appendix B.

6.2 GROUNDWATER ANALYTICAL RESULTS
Laboratory analytical results of the groundwater sample collected from monitoring well MW-2 detected a dissolved
tert-butyl alcohol concentration above its established Interim Maximum Compound Concentration (IMCC). Laboratory
analytical results of the groundwater samples collected from monitoring wells MW-2 and MW-3 detected a dissolved lead
concentration above its established 2L Standard. It should be noted the samples were not collected using low-flow
technology; therefore, it is assumed the lead concentrations are from silt within the samples. A summary of the
groundwater analytical data is presented in Table 4. Dissolved contaminants of concern are depicted on Figure 4. A
copy of the laboratory analytical report is included as Appendix B.

7.0 CONCLUSIONS AND RECOMMENDATIONS
