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 April 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 April 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 well RW01R (1.6 J µg/L);
 Toluene (2L Standard of 600 µg/L) in well GW10R (922 µg/L);
 Ethylbenzene (2L Standard of 600 µg/L) in well GW10R (794 µg/L);
 Total xylenes (2L Standard of 500 ug/L) in wells GW10R (7,080 ug/L) and RW01R (1,530 ug/L);
 MTBE (2L Standard of 20 µg/L) in wells GW38 (32.1 µg/L), RW05 (76.7 µg/L), and RW06 (62.6
µg/L);
 Naphthalene (2L Standard of 6 µg/L) in wells GW10R (433 µg/L) and RW01R (108 ug/L);
 1,2-Dibromoethane (EDB) (2L Standard of 0.02 µg/L) in wells GW10R (3.8 µg/L) and RW01R (0.49
µg/L);
 1,2-DCA (2L Standard 0.4 µg/L) in wells GW20 (20.9 µg/L), GW30 (2.8 µg/L), GW34 (0.46 J ug/L),
GW38 (2.2 ug/L), RW05 (9.4 ug/L), RW06 (2.9 ug/L), and RW11 (0.48 J ug/L);
 1,2,4-Trimethylbenzene (2L Standard of 400 ug/L) in well GW10R (3,570 ug/L);
 1,3,5-Trimethylebenzene (2L Standard of 400 ug/L) in well GW10R (1,030 ug/L);
 Isopropylbenzene (2L Standard of 70 ug/L) in well GW10R (87.4 ug/L);
 n-propylbenzene (2L Standard of 70 ug/L) in well GW10R (87.4 ug/L);
 1,2,3-Trichloropropane (2L Standard of 0.005 ug/L) in well GW20 (0.17 J ug/L);
 Tetrachloroethene (2L Standard of 0.7 ug/L) in well GW20 (0.98 ug/L); and
 Bromodichloromethane (2L Standard of 0.6 ug/L) in well GW34 (0.65 ug/L).

Groundwater analytical results for the April 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); Naphthalene (Figure 5); EDB (Figure 6); and 1,2-DCA (Figure 7).

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 April 2023, the dissolved
benzene plume at the site was estimated to cover an area of approximately 5,120 ft2 resulting in a
calculated dissolved benzene mass of 0.0028 kg. Therefore, the dissolved benzene mass has been
reduced at the site by approximately 99.99% 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 April 2023, the dissolved MTBE plume at the
site was estimated to cover an area of approximately 3,135 ft2 resulting in a calculated dissolved MTBE
mass of 0.19 kg. Therefore, the dissolved MTBE mass has been reduced at the site by approximately
97.25% 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 April 18, 2023. The sample was
transported to SGS and analyzed for VOCs by EPA Method 6200B and Method 504.1 for EDB.
Chloroform was detected in the April 18, 2023, water sample (2.8 µg/L) below the 2L Standard of 70 µg/L.
Chloroform has historically been detected in WSW-1. 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 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 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.

NCDEQ Phillips 66 RM No. 2748
Mr. Brad C. Newton, P.G. May 23, 2023
Page 4

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 October 2023, followed by a semiannual sampling report to be submitted by November 30,
2023.

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 April
2023 sampling event.

The collected data indicated that groundwater samples from 9 monitoring/recovery wells contained dissolved
VOC concentrations that exceeded the respective 2L Standards. The primary contaminant plume continues
to be present around the source area in the northeast corner of the property (near RW01R). Volatile Organic
Compounds (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 decrease in VOCs
since the previous sampling event conducted in October 2022.

Based on the most recent groundwater analytical data from April 2023, the dissolved benzene plume at
the site was estimated to cover an area of approximately 5,120 ft2 resulting in a calculated dissolved
benzene mass of 0.0028 kg. Therefore, the dissolved benzene mass has been reduced at the site by
approximately 99.99%. The dissolved MTBE plume at the site was estimated to cover an area of
approximately 43,135 ft2 resulting in a calculated dissolved MTBE mass of 0.0.19 kg. Therefore, the
dissolved MTBE mass has been reduced at the site by approximately 97.25%.

Chloroform was detected below the 2L Standard in the water sample collected from the Belmont Abbey

WSW in April 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.
