1.0 SITE DESCRIPTION

Phillips 66 Company (Phillips 66) authorized ATC Associates of North Carolina, P.C. (ATC) to provide
environmental consulting services for Circle K Store No. 8379. The site is located at 101 Belmont-Mount
Holly Road in Belmont, North Carolina. Until 2012, the property included a single-story convenience store
building and a retail gasoline distribution system, which included three underground storage tanks (USTs),
dispensing pumps, and associated piping. The developed part of the site was mostly covered by asphalt
pavement with minor landscaped areas and had access only to Belmont Mount Holly Road. In September
2012, site redevelopment construction was initiated, and the activities consisted of demolition of the existing
convenience store facility, which included removal of the UST system and the original site groundwater
treatment system (GWTS). Store redevelopment was completed, including re-installation of onsite remedial
components and two 10,000-gallon gasoline USTs and dispensers. The store now has entrances on
Woodlawn Road and Belmont-Mount Holly Road. Figure 1 shows the site location on a topographic map.
Figure 2 shows the locations of the monitoring wells and remediation wells.

The site vicinity is situated in a commercial, residential, and institutional area of Belmont, North Carolina;
however, the immediate site vicinity has a rural character. The site is bordered to the east-southeast by
Belmont-Mount Holly Road and the grounds of Belmont Abbey College (location of water supply well 800
feet south); to the west-southwest by Woodlawn Road; and to the north by the Colonial Plantation Pipeline
right-of-way and undeveloped wooded land.

2.0 SITE HISTORY

In December 1992, one of the three USTs, containing unleaded gasoline, was suspected of leaking. An
initial investigation was conducted by Delta Environmental Consultants, Inc. (Delta) in early 1993. In June
1993, light non-aqueous phase liquid (LNAPL) was discovered in monitoring well MW-3, and preliminary
corrective action (manual bailing) was implemented. A Comprehensive Site Assessment (CSA) was
completed by Delta in October 1993. During investigation activities, petroleum hydrocarbons were detected
in the soil and groundwater samples collected at the site. A Corrective Action Plan (CAP) was completed
by ATEC Associates, Inc. in 1994, followed by startup of a soil and GWTS in June 1995. A system
enhancement was completed in July 2004.

On September 5, 2012, Circle K began site construction activities for a new, larger convenience store
facility. The work included the demolition of the old store, removal of the UST’s and dispensers, construction
of a new store, installation of new USTs and dispensers, and repaving of the site. During redevelopment
activities, 918 tons of petroleum-impacted soil near and beneath the former UST system were excavated
and properly disposed at a permitted facility in an effort to reduce secondary source mass and to aid in
groundwater remediation. On-site monitoring and remedial system wells were reinstalled and monitored
during the subsequent sampling events, and ATC restarted the GWTS on September 16, 2013.

Recovery wells RW03R, RW04R, RW07, RW10, RW11, and RW12 were de-activated in March 2018, as
requested by the NCDEQ in a letter dated February 12, 2018.

The GWTS has recovered impacted groundwater from the Circle K property and the Belmont Abbey College
property. Groundwater is recovered with pneumatic pumps and is then treated using an air stripper and bag
filters, prior to discharge. The groundwater is discharged in accordance with National Pollution Discharge
Elimination System (NPDES) General Permit No. NCG510000. In response to the prior June 11, 2019,
Active Remediation Monitoring Report, the DEQ determined that the GWTS should be de-activated. From
June 2019 through late June 2022, Phillips 66 elected to continue funding operation of the GWTS. On June
21, 2022, the GWTS was shut down to investigate alternative remedial methods to complete remediation
at the site.

3.0 GROUNDWATER CHARACTERIZATION

3.1 Groundwater Levels

Well construction details for the monitoring wells are summarized in Table 1. On October 17-18, 2023,
groundwater levels were measured in the site monitoring well network. An oil/water interface probe was used
to measure the depths to groundwater from the top of well casing. Groundwater elevations were then calculated
based on the measured elevations, which are referenced to an arbitrary on-site benchmark of 100.00 feet. The
locations of the monitoring wells are shown in Figure 2, and the groundwater elevation data are summarized
in Table 2. A groundwater elevation contour map based on the recent gauging data is included as Figure 3.
Based on the results, the groundwater flow direction is generally towards the southwest, which is consistent
with previous interpretations.

3.2 Groundwater Quality

On October 17-18, 2023, groundwater samples were collected from the site monitoring well and recovery well
network. The groundwater samples were transported under chain of custody documentation to North Carolina-
accredited SGS Acutest Laboratories (SGS), located in Orlando, Florida. The groundwater samples were
analyzed by EPA Method 6200B for volatile organic compounds (VOCs) including the following petroleum
constituents: benzene, toluene, ethylbenzene, total xylenes (BTEX), methyl tertiary butyl ether (MTBE),
isopropyl ether (IPE), naphthalene, and 1,2 dichloroethane (1,2-DCA), and by Method 504.1 for 1,2-
dibromoethane. The laboratory report is included in Appendix A.

The groundwater samples exceeded the NCDEQ Groundwater Quality 2L Standards for the following VOCs:

 Benzene (2L Standard of 1.0 µg/L) in wells GW10R (16.6 µg/L), GW20 (1.1 µg/L), RW01R (27.3 µg/L),

Groundwater analytical results for the October 2023 sampling event are summarized in Table 3, and historical
groundwater analytical results are summarized in Table 4. Iso-concentration maps are provided for the
following constituents: BTEX (Figure 4); benzene (Figure 5); MTBE (Figure 6); Naphthalene (Figure 7); EDB
(Figure 8); and 1,2-DCA (Figure 9). An additional contaminants of concern in groundwater map depicting
concentrations exceeding applicable 2L Standards is included as Figure 10.

Benzene Removal
In 1994, the dissolved benzene contaminant mass at the site was estimated to cover an area approximately
29,000 square feet (ft2) resulting in a calculated dissolved benzene baseline mass of 360 kilograms (kg).
Based on the most recent groundwater analytical data from October 2023, the dissolved benzene plume at
the site was estimated to cover an area of approximately 7,492 ft2 resulting in a calculated dissolved
benzene mass of 0.121 kg. Therefore, the dissolved benzene mass has been reduced at the site by
approximately 99.97% based on the most recent analytical data. The contaminant mass calculations are
provided in Table 5 and benzene contaminant mass removal is provided in Table 6.

MTBE Removal
In 1994, the dissolved MTBE contaminant mass at the site was estimated to cover an area approximately
9,750 square feet (ft2) resulting in a calculated dissolved MTBE baseline mass of 6.9 kilograms (kg). Based
on the most recent groundwater analytical data from October 2023, the dissolved MTBE plume at the site
was estimated to cover an area of approximately 2,667 ft2 resulting in a calculated dissolved MTBE mass
of 0.40 kg. Therefore, the dissolved MTBE mass has been reduced at the site by approximately 94.20%
based on the most recent analytical data. The contaminant mass calculations are provided in Table 5 and
MTBE contaminant mass removal is provided in Table 7.

3.3 Water Supply Well Sampling

The WSW located at Belmont Abbey College (WSW-1) was sampled on October 18, 2023. The sample
was transported to SGS and analyzed for VOCs by EPA Method 6200B and Method 504.1 for EDB.
Chloroform has historically been detected in WSW-1 and was detected at a concentration of 2.0 µg/L during
the October 2023, sampling event. This concentration does not exceed below the 2L Standard of 70 µg/L.
Methyl chloride and acetone were detected at concentrations of 0.28 µg/L and 2.1 µg/L, respectively. These
concentrations do not exceed the applicable NCDEQ 2L Standard and are common laboratory
contaminants. No other compounds were detected at concentrations above the respective method
detection limits. Historical laboratory results for the Belmont Abbey WSW are summarized in Table 8. The
laboratory report for the October 2023 sampling event is included in Appendix A.

According to Belmont Abbey College maintenance personnel, the Belmont Abbey WSW is one of two
sources of water for the college campus. The college is also connected to city water, which serves as an
alternative water supply in the event that the WSW is shut down or needs to be supplemented during
periods of excess demand.

4.0 GROUNDWATER TREATMENT SYSTEM

4.1 Groundwater Treatment System

The current GWTS is located at the northeast corner of the Circle K store property adjacent to the dumpster
enclosure. The previous GWTS was removed during demolition activities in September 2012 and was
replaced with an updated GWTS in September 2013. Following demolition activities for Circle K site
redevelopment, five monitoring wells and four recovery wells were installed to replace the wells that were
abandoned during site redevelopment. Additionally, four air sparge wells were installed to enhance remedial
activities on the site. The GWTS utilizes two separate air compressors; one to provide compressed air for
air sparging, and the other to provide compressed air for 12 pneumatic well pumps that remove groundwater
for treatment. The submersible pneumatic pumps are supplied with air through two trunk lines, one each
for the four on-site wells and for the eight, off-site down gradient wells. The pumps evacuate water from the
NCDEQ Phillips 66 RM No. 2748
Mr. Brad C. Newton, P.G. November 28, 2023
Page 4

shallow aquifer through individual lines to the GWTS. In a letter dated February 12, 2018, the NCDEQ
requested that recovery wells RW03R, RW04R, RW07, RW10, RW11 and RW12 be de-activated.

Extracted groundwater is collected by a manifold system and delivered to a 100-gallon double walled
holding tank. A float-switch activated transfer pump delivers water in batches to an air stripper for treatment,
and a float-switch activated pump discharges water from the stripper sump in batches to the discharge line.
The volume of treated groundwater is measured with a totalizing flow meter. The GWTS is plumbed so that
activated carbon can be added to the discharge, although no carbon is currently needed or anticipated for
the GWTS to meet discharge limits referenced in the NPDES discharge permit. The effluent from the GWTS
is discharged to a NPDES outfall at an unnamed tributary to Fites Creek, north of the site. Sensors for high
level conditions and a sensor in a trailer-body sump are interlocked with the GWTS power supply so that
operation of the GWTS will cease if high-level or water overflow conditions occur.

4.2 System Sampling

Since the GWTS was shut down in June 2022 to investigate alternative remedial methods to complete site
remediation, no quarterly influent and effluent groundwater samples were collected following the April 2022
sampling event. Historical laboratory results for influent and effluent samples (since 2016) are summarized
in Table 9.

4.3 System Status

On September 16, 2013, ATC activated the new GWTS. Although the NCDEQ determined the GWTS
should be de-activated in a letter dated June 19, 2019, Phillips 66 elected to continue funding operation of
the GWTS through late June 2022. On June 21, 2022, the GWTS was shut down to investigate alternative
remedial methods to complete remediation at the site.

5.0 MONITORING AND REPORTING PLAN

The next semiannual sampling of the groundwater monitoring wells and the Belmont Abbey WSW is
proposed for April 2024, followed by a semiannual sampling report to be submitted by May 31, 2024.

6.0 SUMMARY AND CONCLUSIONS

During this reporting period, ATC measured groundwater levels and collected groundwater samples from the
site monitoring and recovery well network. ATC also collected a water sample from the Belmont Abbey WSW.
On June 21, 2022, the GWTS was shut down to investigate alternative remedial methods to complete
remediation at the site, therefore, no influent or effluent samples were collected during the October 2023
sampling event.

The collected data indicated that groundwater samples from ten (10) monitoring and/or recovery wells
contained dissolved volatile organic compound (VOC) concentrations that exceeded the respective NCDEQ
2L Standards. The primary contaminant plume continues to be present around the source area in the northeast
corner of the property (near GW10R and RW01R). Based on a review of the historical analytical groundwater
data, VOC concentrations are mostly stable in the monitoring well network. Monitoring wells GW10R and
RW01R, which have historically contained the highest impacts, indicated an overall increase in VOCs since
the previous sampling event conducted in April 2023. Additionally, VOC concentrations in well GW10R have
decreased when compared to the October 2022 sampling event. In comparison, VOC concentrations in well
RW01R have increased when compared to the October 2022 sampling event.

Based on the most recent groundwater analytical data from October 2023, the dissolved benzene plume at
the site was estimated to cover an area of approximately 7,492 ft2 resulting in a calculated dissolved
benzene mass of 0.121 kg. Therefore, the dissolved benzene mass has been reduced at the site by
approximately 99.97% based on the most recent analytical data. The dissolved MTBE plume at the site
NCDEQ Phillips 66 RM No. 2748
Mr. Brad C. Newton, P.G. November 28, 2023
Page 5

was estimated to cover an area of approximately 2,667 ft2 resulting in a calculated dissolved MTBE mass
of 0.40 kg. Therefore, the dissolved MTBE mass has been reduced at the site by approximately 94.20%
based on the most recent analytical data.

Acetone, chloroform, and methyl chloride were detected below the 2L Standard in the sample collected
from the Belmont Abbey WSW in October 2023. No other compounds were detected at concentrations
above the respective method detection limits.

7.0 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.
