2.0 EXECUTIVE SUMMARY

ATC Associates of North Carolina, P.C. (ATC) has completed a Free Product Recovery and Groundwater
Monitoring Report for the Former Circle K Store No. 8705 site located at 3920 The Plaza in Charlotte,
Mecklenburg County, North Carolina. This report documents the groundwater sampling activities conducted
at the site in August 2022.

The site consists of a single-story brick building, an underground storage tank (UST) system, and fuel island
canopy. The UST system consists of three 10,000-gallon gasoline USTs and associated product piping and
dispensers. The property is currently owned by DCMP, LLC and occupied by PC Mart 1015.

On February 23, 2023, ATC supervised an AFVR event at the site. The event was conducted in order to
abate light non-aqueous phase liquid (LNAPL) historically detected in MW-4, MW-8 and MW-13 and reduce
the volatile organic compound (VOC) concentrations in the center of the plume mass. A total of 1,702
gallons of petroleum impacted groundwater was recovered during the AFVR event.

On February 28 and March 1, 2023. ATC personnel mobilized to the site to gauge groundwater and/or light
non-aqueous phase liquid (LNAPL) levels and to collect groundwater samples from all existing monitoring
wells (MW-1 through MW-16, DMW-1, RW-1, and RW-2/OW-1). LNAPL was detected in wells MW-4, MW-
8, and MW-13. Numerous compounds were detected at concentrations exceeding the NCDEQ Groundwater
Quality 2L Standards (2L Standards) in monitoring wells MW-3, MW-5, MW-6, MW-7, MW-9 through MW-
12, DMW-1, RW-1, and RW-2/OW-1. One or more compounds of concern exceeded the GCLs in samples
from monitoring wells MW-7, MW-10, MW-12, DW-1, RW-1, and RW-2/OW-1, respectively.

ATC is currently performing bi-weekly O&M visits at the site to ensure proper remedial system operation.
Remedial performance data are recorded during O&M visits, including air flow recovery rates, sparge and
vacuum pressures, hour meter readings, and off-gas concentrations, to track and evaluate system
operating conditions and to maintain remedial efficiency. The average runtime for the system (not including
downtime for scheduled maintenance and groundwater sampling) is approximately 100% from September
2022 through February 2023.

ATC recommends continued AS/SVE system O&M activities and semiannual sampling of the associated
monitoring well network to evaluate groundwater quality conditions and system effectiveness. ATC also
recommends continued quarterly monitoring of LNAPL levels as it is suspected that detectable LNAPL
appears during period of lower groundwater elevation in the center of plume mass. AFVR events shall be
scheduled if LNAPL is detected. The next semiannual sampling event for all the monitoring wells is
scheduled for August 2023.

3.0 INTRODUCTION

Phillips 66 Company (Phillips 66) retained ATC Associates of North Carolina, P.C. (ATC) to provide
environmental consulting services for the Circle K No. 8705 facility, Phillips 66 Risk Management (RM) Site
No. 5130, located at 3920 The Plaza, Charlotte, Mecklenburg County, North Carolina. The scope of work
summarized in this report includes remedial system O&M efforts and a quarterly groundwater monitoring
event.

The property consists of a single-story convenience store building and a retail gasoline distribution system,
which includes three underground storage tanks (USTs), dispensing pumps, and associated piping. The
site is mostly covered by asphalt pavement with minor landscaped areas. Figure 1 shows the site location
on a topographic map. A site map showing site features and layout is included as Figure 2. The site is
situated in a commercial/residential area and is bordered to the north by The Plaza Road and residential
housing beyond; to the east by East Sugar Creek Road and commercial retail offices beyond; and to the
south and west by residential properties. The site has a risk classification of Intermediate I-170D.

4.0 SITE BACKGROUND

A release was reported to The North Carolina Department of Environmental Quality (NCDEQ) on March
18, 2004, based on the findings of a due diligence investigation that was performed in January 2004. The
NCDEQ issued a Notice of Regulatory Requirements (NORR) on May 23, 2008 and requested that a Site
Check assessment be performed to evaluate potential sources of the detected subgrade petroleum
contamination. The site check performed in July 2008 found impact, and Limited Site Assessment (LSA)
tasks were completed in July and October of 2008. The release incident risk designation was intermediate
based on the presence of Light Non-Aqueous Phase Liquid (LNAPL) and no receptors. A Free Product
Assessment Report was completed in July 2009 to comply with a Notice of Regulatory Requirements
(NORR) issued by the NCDEQ in February 2009. The LNAPL assessment included the use of bail-down
tests to help evaluate the magnitude of LNAPL in well MW-4. A groundwater monitoring event was
performed in July 2011, and an AFVR event with subsequent sampling was performed in April 2012. In
November 2012, an AFVR event was conducted with subsequent groundwater monitoring conducted in
December 2012.

In 2013, additional monitoring wells were installed and an updated receptor survey was performed which
did not identify supply wells or surface water bodies within 1,500 feet from the site. Later in 2013, ATC
collected a LNAPL sample from well MW-4 and from the nearest UST for laboratory analyses. The
fingerprint review identified that the product observed in the monitoring wells was similar in composition to
the gasoline from the UST. ATC requested that tank tightness testing be performed and that a review of
UST inspection records be performed to determine if a new release had occurred. In 2014 the
owner/operator’s environmental consultant performed tank tightness testing and presented a case that a
new release did not occur. In 2015 the DEQ indicated that there was no conclusive evidence to support a
new release. ATC performed multiple AFVR events in 2016 to reduce petroleum impact including LNAPL
recovery. LNAPL continued to be present in the monitoring well network, therefore, additional monitoring
wells were recommended to further assess the source area.

Between July 10 through July 13, 2017, ATC supervised the installation of six (6) shallow, groundwater
monitoring wells (MW-8, MW-9, MW-10, MW-11, MW-12, and MW-13), and one recovery well (RW-1).
Following monitoring well installation, ATC returned to the site on August 17, 2017, to collect soil gas
samples from monitoring wells MW-5, MW-11, and MW-12 to preliminarily screen subsurface conditions for
soil gas quality. On August 25, 2017, ATC collected groundwater samples from newly installed monitoring
wells and wells near the source area, including wells MW-3, MW-5, MW-7, MW-8, MW-9, MW-10, MW-11,
MW-12, MW-13, and RW-1. These samples were collected as baseline samples for the new wells prior to
performing an AFVR remedial event. No LNAPL was detected in these newly installed wells during this
monitoring event.

Multiple LNAPL removal AFVR events have been performed at the site since 2017. Due to the recurrence
of LNAPL in in monitoring well MW-4, remedial alternatives were evaluated in a Corrective Action Plan
(CAP). As part of the development of the CAP, ATC installed one additional recovery well (RW-2), one AS
well (AS-1), and one SVE well (SVE-1) for pilot testing activities. The June 1, 2018, CAP identified AS/SVE
as the recommended remedial strategy for this site.

Between November 30, 2018, through December 7, 2018, ATC supervised the installation of five (5) AS
wells, and six (6) SVE wells, performed by a licensed well driller. Monitoring well construction details are
included in Table 1. Between December 17, 2018, and January 3, 2019, ATC supervised the remedial
system trenching and piping construction work, performed by Zebra Environmental Services (Zebra).
These activities included the air knifing excavation and heavy equipment excavation of the remedial piping
trenches. For potential remedial system expansion needs, ATC installed an additional two-inch diameter
and one-inch diameter SVE/AS, Schedule 80 PVC lines within the excavated trenches up to SVE well
locations SVE-4 and SVE-7, in case additional remedial wells may be needed in the future if plume
conditions change.

On February 26, 2019, ATC conducted a baseline groundwater monitoring event and collected groundwater
samples from monitoring wells MW-1 through MW-3, MW-5 through MW-12, MW-14 through MW-16, and
recovery wells RW-1 and RW-2/OW-1. Samples were not collected from wells MW-4 and MW-13 due to
the presence of LNAPL (0.17 feet in each well). Analytical results indicated that the Gross Contamination
Levels (GCLs) were exceeded in one of more compounds of concern in samples from monitoring wells
DMW-1, MW-5, MW-7, MW-8, MW-9, MW-10, MW-11, MW-12, RW-1, and RW-2/OW-1.

Between April 4 and April 10, 2019, the AS/SVE remedial system was delivered to the site, the utility riser
pole for electric service was placed, and the electric meter box and wiring was installed to the remedial
system trailer by Product Recovery Management (PRM). On May 7, 2019, following final electrical permit
inspection and approval by Mecklenburg County, and overhead power delivery to the site by Duke Power,
ATC conducted system startup activities with PRM. ATC submitted a Remedial System Startup Report on
July 25, 2019, describing remedial system installation activities and startup. Since SVE startup a
groundwater monitoring event was conducted on October 16-17, 2019, and an 8-hour AFVR free-product
removal event was conducted on October 31, 2019.

On January 29-30, 2020 ATC conducted a quarterly groundwater monitoring event that included the
gauging and sampling of wells MW-1 through MW-16 and DMW-1. LNAPL was not detected during this
event.

ATC also returned to the site on April 8, 2020, to gauge source area monitoring wells for the presence of
Light Non-Aqueous Phase Liquid (LNAPL). Wells MW-1, MW-3, MW-4, MW-5, MW-7, MW-8, MW-9, MW-
10, MW-11, MW-12, MW-13, and DMW-1 exist in the target remedial source area and were gauged to see
if LNAPL was present. No LNAPL was detected; however, the average depth to water at that time was
21.53 feet below top of well casings (ft. btoc). The thickest amount of LNPAL was measured at the site on
April 9, 2013 in MW-4 with LNAPL detected at 28.56 ft. btoc and the depth to groundwater at 32.00 ft. btoc
with an LNAPL thickness of 3.44 feet. The depth to groundwater in MW-4 during the May 7, 2020 event
was 21.50 ft. btoc.

On May 6-7, 2020, ATC conducted a quarterly groundwater monitoring event that included the gauging and
sampling of wells MW-1 through MW-16 and DMW-1. LNAPL was not detected during this event.

On September 10-11, 2020 ATC conducted a quarterly groundwater monitoring event that included the
gauging and sampling of wells MW-1 through MW-16 and DMW-1. LNAPL was detected in MW-4 at 23.12
ft. btoc and groundwater was measured at 23.17 ft. btoc. MW-9 LNAPL was also measured 23.57 ft. btoc
and groundwater was measured to be 23.58 ft. btoc. MW-4 LNAPL thickness was 0.05 ft. and MW-9 LNAPL
thickness was measured to be 0.01 ft.

On February 4-5, 2021 ATC conducted a quarterly groundwater monitoring event that included the gauging
and sampling of wells MW-4, MW-5, MW-7 through MW-13, DMW-1, RW-1, and RW-2. LNAPL was
detected in MW-8 at 19.30 ft. btoc and groundwater was measured at 19.33 ft. btoc. MW-8 LNAPL thickness
was 0.03 ft.

On May 20, 2021 ATC conducted an 8-hour AFVR event on monitoring wells MW-4, MW-8, and RW-2 to
address LNAPL and reduce dissolved phase contaminant concentrations. A total of 2,005 gallons of
petroleum impacted groundwater and 2.75 gallons of petroleum impacted vapor were recovered during the
event.

On May 24, 2021 ATC conducted a quarterly groundwater monitoring event that included the gauging and
sampling of monitoring wells MW-4, MW-5, MW-7, MW-8, MW-9, MW-10, MW-11, MW-12, MW-13, DMW-
1, RW-1, and RW-2. LNAPL was not detected during the May 2021 event.

On August 17-18, 2021 ATC conducted a quarterly groundwater monitoring event that included the gauging
and sampling of monitoring wells MW-1, MW-2, MW-3, MW-4, MW-5, MW-6, MW-7, MW-8, MW-9, MW-
10, MW-11, MW-12, MW-13, MW-14, MW-15, MW-16, DMW-1, RW-1, and RW-2. LNAPL was not detected
during the August 2021 event.

On November 22, 2021 ATC conducted a quarterly groundwater monitoring event that included the gauging
and sampling of monitoring wells MW-4, MW-5, MW-7, MW-8, MW-9, MW-10, MW-11, MW-12, MW-13,
DMW-1, RW-1, and RW-2. LNAPL was detected in monitoring wells MW-4 and MW-8 with a thickness of
0.06 ft and 0.47 ft, respectively.

ATC performed an AFVR event on monitoring wells MW-4, MW-8, and RW-1 on February 8, 2022 which
generated approximately 1,944 gallons of petroleum impacted groundwater and 6.93 gallons of petroleum
impacted vapor. Subsequently, on March 7 and 8, 2022, ATC conducted a comprehensive groundwater
sampling event at the site. Monitoring wells MW-2 through MW-16, DMW-1, RW-1, and RW-2/OW-1 were
gauged for groundwater and/or LNAPL levels. LNAPL was not detected in any of the monitoring wells.

ATC performed an AFVR event on monitoring wells MW-4, MW-8, and RW-1 on October 11, 2022 which
generated approximately 2,065 gallons of petroleum impacted groundwater. Subsequently, on August 29
and 30, 2022, ATC conducted a comprehensive groundwater sampling event at the site. Monitoring wells
MW-2 through MW-16, DMW-1, RW-1, and RW-2/OW-1 were gauged for groundwater and/or LNAPL
levels. LNAPL was not detected in any of the monitoring wells.

This report summarizes the February quarterly groundwater monitoring event of all existing monitoring wells
and the February 2023 AFVR event.

5.0 AGGRESSIVE FLUID VAPOR RECOVERY EVENT

In an attempt to remove LNAPL and reduce the volatile organic compound (VOC) concentrations in the
center of the plume mass, ATC performed an AFVR event on monitoring wells MW-4, MW-8, MW-13, and
RW-1 on February 23, 2023. Haz-Mat Environmental was subcontracted to perform the AFVR event. Prior
to performing the event, monitoring wells RW-1, MW-4, MW-8, and MW-13 were gauged for liquid levels.
LNAPL thickness was not detected. LNAPL was also not detected in monitoring wells MW-4, MW-8, MW-
12, and RW-1 prior to the AFVR event. Monitoring well construction details are included as Table 1.
Groundwater elevation data from the AFVR event is included as Table 2.

During AFVR activities, a liquid ring vacuum pump unit is plumbed to the designated extraction point, and
a drop “stinger” pipe is extended into the well through an airtight seal at the top of the well casing (TOC)
and into the water column. Throughout the AFVR process, a cone of depression forms around a designated
recovery point by drawing down the groundwater surface levels, thus causing impacted water surrounding
the recovery point to be extracted. Soil petroleum vapor within the cone of depression and the overlying
vadose zone are removed as vapor by air passing through the soil.

The February 23, 2023, AFVR event generated approximately 1,702 gallons of petroleum impacted
groundwater and 3.91 gallons of petroleum impacted vapor. The waste disposal manifest and AFVR
calculations from the AFVR event are provided in Appendix A. LNAPL was not detected in MW-4, MW-8,
MW-13, and RW-1 following the AFVR event.

6.0 GROUNDWATER ASSESSMENT ACTIVITIES

6.1 GROUNDWATER LEVELS

On February 28 and March 1, 2023, ATC conducted a comprehensive groundwater sampling event at the
site. Monitoring wells MW-1 through MW-16, DMW-1, RW-1, and RW-2/OW-1 were gauged for
groundwater and/or LNAPL levels. An oil/water interface probe was used to measure fluid levels. Due to an
equipment malfunction, LNAPL was not detected any of the gauged wells. During the initial purge, LNAPL was
encountered in wells MW-4, MW-8, and MW-12. Depths to groundwater ranged from approximately 22.69 to
28.99 feet below well top of casings (ft btoc).

The locations of the monitoring wells are shown in Figure 2 and Figure 2A. Monitoring well construction
details are summarized in Table 1. Groundwater elevation data is summarized in Table 2. A groundwater
elevation contour map is included as Figure 3. Based on review of this data, the groundwater flow direction
is generally southward, which is consistent with historical groundwater flow interpretations. Graph 1 and
Graph 2 are included as LNAPL thickness versus groundwater elevation data in wells MW-4 and MW-13,
respectively.

6.2 GROUNDWATER QUALITY

On February 28 and March 1, 2023, groundwater samples were collected from monitoring wells MW-1
through MW-3, MW-5 through MW-7, MW-9 through MW-12, MW-14 through MW-16, DMW-1, RW-1, and
RW-2/OW-1. The sampled monitoring wells were purged of three well volumes of groundwater before
sample collection using a disposable bailer. Prior to well purging, LNAPL was not detected in monitoring
wells MW-4, MW-8, and MW-13; however, LNAPL was detected following the purging of the first well
volume. Therefore, MW-4, MW-8, and MW-13 were not sampled. The LNAPL thickness ranged from a
sheen to less than 0.04 feet.

The groundwater samples were collected in laboratory-supplied and preserved containers, placed on ice,
and shipped in accordance with chain-of-custody protocol to North Carolina-accredited SGS Accutest, in
Orlando, Florida for analyses. The groundwater samples were analyzed by EPA Standard Method 6200B for
volatile organic compounds including benzene, toluene, ethylbenzene, total xylenes (BTEX), methyl tertiary
butyl ether (MTBE), isopropyl ether (IPE), and naphthalene.

The laboratory analytical results indicated that VOCs were detected at concentrations exceeding the 2L
Standards in monitoring wells MW-1, MW-3, MW-5, MW-6, MW-7, MW-9 through MW-12, DMW-1, RW-1,
and RW-2/OW-1.

The analytical results indicated the following compounds exceeded the GCL Standards:

 Benzene: MW-7 (15,200 micrograms per liter [ug/L]), MW-10 (15,300 ug/L), MW-12 (16,100 ug/L),
DMW-1 (5,690 ug/L), and RW-1 (20,300 ug/L); and
 1,2-Dichloroethane: MW-10 (723 ug/L) and MW-12 (1,450 ug/L).

Laboratory analytical results for the February 28 and March 1, 2023 event is summarized in Table 3.
Historical groundwater analytical results are summarized in Table 4. Concentration versus time graphs are
included as Graph 3. Figure 4 depicts Total BTEX isoconcentration contours to show the inferred extent
of the plume mass based on the analytical results of the February 2023 event. The laboratory analytical
report and chain-of-custody forms are included in Appendix B.

Benzene Removal
In 2018, the dissolved benzene contaminant mass at the site was estimated to cover an area approximately
12,500 square feet (ft2) resulting in a calculated dissolved benzene baseline mass of 10,986.2 kilograms
(kg). Based on the most recent groundwater analytical data (February 2023), the dissolved contaminant
mass at the site was estimated to cover an area approximately 12,500 ft2 resulting in a calculated dissolved
benzene mass of 423.7 kg. Therefore, the dissolved benzene mass has been reduced at the site by
approximately 93.25% compared to the 2018 baseline mass. The contaminant mass calculations are
provided in Table 5 and contaminant mass removal is provided in Table 6. Contaminant mass removal
versus time is provided in Graph 4.

1,2-Dichloroethane Removal
In 2018, the dissolved contaminant mass at the site was estimated to cover an area approximately 2,600
square feet (ft2) resulting in a calculated dissolved 1,2-dichloroethane baseline mass of 10,131.2 kilograms
(kg). Based on the most recent groundwater analytical data (February 2023), the dissolved contaminant
mass at the site was estimated to cover an area approximately 2,600 ft2 resulting in a calculated dissolved
1,2-dichloroethane mass of 3.40 kg. Therefore, the dissolved 1,2-dichloroethane mass has decreased by
approximately 99.97% compared to the 2018 baseline mass. The contaminant mass calculations are
provided in Table 5 and contaminant mass removal is provided in Table 7. Contaminant mass removal
versus time is provided in Graph 4.

7.0 REMEDIATION SYSTEM OPERATIONS AND MAINTENANCE

The SVE remedial system was activated for continuous operation on May 7, 2019 and is currently in
operation at the site. The SVE system consists of a Rotron, 3-phase 15 Hp regenerative vacuum blower
capable of 112 inches of water column (H2O”) at 150 cfm. The SVE well network is comprised of
Observation Well OW-1 (screened from 10-40 feet below ground surface [ft bgs]), Recovery Well RW-1
(screened from 5-40 ft bgs), and SVE wells SVE-1 through SVE-7, which are screen from 5 to 30 feet below
ground surface.

The AS blower is a Gardner Denver Rietschle 10 horsepower (Hp), 3-phase unit capable of 31 pounds per
square inch (psi) pressure at 62 cubic feet per minute (cfm) flow. Air sparge operation was not performed
during the approximate first year of system operation to prevent mobilization of the LNAPL plume away
from the center of plume mass. As LNAPL has not been present in surrounding wells of the remedial well
network, air sparge operation was activated in July 2020 in perimeter portions of the source area and
remedial well network. Currently, sparge wells AS-1 and AS-3 are active.

ATC is currently performing bi-weekly O&M visits at the site to ensure proper remedial system operation.
Remedial performance data are recorded during O&M visits, including air flow recovery rates, sparge and
vacuum pressures, hour meter readings, and off-gas concentrations, to track and evaluate system
operating conditions and to maintain remedial efficiency. The average runtime for the system (not including
downtime for scheduled maintenance and groundwater sampling) is approximately 100% from September
2022 through February 2023.

Based on the historical groundwater analytical results presented in Table 4, VOCs have been reduced
below the respective GCLs in monitoring wells MW-5, MW-9, MW-11, and RW-2/OW-1, which are located
in the near vicinity of the active air sparge wells (AS-1 and AS-3).

 Based on the mass removal calculations, benzene has been reduced by approximately 93.25%,
while 1,2-dichloroethane concentrations have been reduced by 99.97% since May 2018.

 Based on the historical groundwater analytical results, VOCs have been reduced below the
respective GCLs in monitoring wells MW-5, MW-9, MW-11, and RW-2/OW-1 which are located in
the near vicinity of the active sparge wells (AS-1 and AS-3).

 ATC is currently performing bi-weekly O&M visits at the site to ensure proper remedial system
operation. The average runtime for the system (not including downtime for scheduled maintenance
and groundwater sampling) is approximately 100% from September 2022 through February 2023.

Based on this information, ATC offers the following recommendations:

 Continue AS/SVE system O&M activities and groundwater monitoring to evaluate groundwater
quality conditions and system effectiveness;

 Continue to monitor LNAPL levels in the center of plume mass. Perform additional AFVR events if
LNAPL is detected; and

 Gradually activate more AS wells located closer to the center of plume mass if LNAPL is not
detected.

9.0 REPORT LIMITATIONS

This investigation is intended to be a non-biased assessment of on-site environmental conditions proximate
to the location of the former and/or current UST system. Subsurface investigative and remedial
methodologies were performed in general accordance with applicable state and federal regulatory
requirements. The information presented in this report is based upon site-specific observations, generally
accepted geological and environmental consulting practices, and analytical results for environmental
samples collected at the time the field investigation was performed. The data presented in this report are
believed to represent subsurface conditions at the facility; however, data may not be completely
representative of subsurface conditions at every location. ATC assumes no liability arising from
environmental impact to, or from, the site, regardless of the date of impact occurrence or findings.

RE: AFVR Services for RM-5130 at 3920 The Plaza Charlotte, NC

Dear Rick:
HAZ~MAT Environmental Services, Inc (HAZ~MAT) is pleased to submit this information
pertaining to the AFVR performed at the above site in Charlotte, NC on February 23, 2023.

AFVR Event Information
➢ The AFVR event was performed as an 8-Hour event on monitor wells MW-4, MW-8, and
RW-1. Each stinger pipe was set at approximately 27 ft. below land surface.
➢ Magnehelics gauge readings were taken every 30-60 minutes beginning at 8:00 am and
concluding at 16:00 pm. Magnehelic readings were taken from a ball-valve port on the
emissions stack and consisted of air flow, temperature (ºF), photo-ionizing detector readings
(ppm), and specific humidity. The truck vacuum gauge (Hg) was utilized to determine
operating vacuum level. No rain was encountered during the 8-hr event.
➢ A total of 1,702-gallons of total liquids were removed via vacuum truck, manifested, and
transported to Dart-A Clean Earth Company, located in Charlotte, NC on February 24, 2023.
(Copy of manifest attached)
➢ A volume of 24.42 Total Emissions (Pounds) or 3.91 Total Emissions (Gallons) were
generated from the event. A copy of the AFVR Data Sheet-Emissions Data and Calculation
table is attached.

Attached for your review is the field data.

HAZ~MAT very much appreciates the opportunity to be of service on this site and hope that you will
allow us to provide similar services for future activities.

Sincerely,
Curtis Helms, Jr.
Environmental Health & Safety Manager
