NCDEQ Incident No. 14645
Risk Classification: High (380D)
ATC Project No. P66-2751-000
Dear Ms. Beverly:
On behalf of Phillips 66 Company (P66), ATC Associates of North Carolina, P.C., (ATC) has
performed environmental consulting services for the Circle K Store No. 8387 (Phillips 66
Risk Management [RM] No. 2751) facility. The site is located at 8425 Highway 49 North,
Mt. Pleasant, North Carolina. The property consists of an active single -story convenience
store building and retail gasoline distribution system, which includes three underground
storage tanks (USTs), dispensing pumps, and associated piping. The site is mostly covered by
asphalt and concrete pavement with landscaped areas located on the northern part of the
property. Figure I shows the site location on a topographic map, and a site map showing the
locations of the monitoring wells and inactive remediation wells is included as Figure 2.
ATC is pleased to submit this report documenting an updated groundwater monitoring event
and the installation of Regenesis Oxygen Releasing Compound Advanced Filter Socks®
(ORC socks) in select monitoring wells at the site.
Background
An initial round of ORC socks were installed in wells GWO1, GW04, GW05 and GW14D on
January 5, 2018. Previous groundwater monitoring events had indicated the presence of
ethylene dibromide (EDB) in wells GWO1, GW04 and GW05 at concentrations above the
North Carolina Title 15A, NCAC, Subchapter 2L, Part .0202 Standards (2L Standards). ORC
socks were installed in well GW 14D due to a historical presence of MTBE at concentrations

that were near the 2L Standard. Groundwater monitoring conducted in 2018 after the
installation of the ORC socks showed that EDB concentrations in wells GWO1, GW04 and
GW05 had decreased to concentrations below the 2L Standard. However, benzene
concentrations in well GW02 increased to above the 2L Standard. Therefore, on January 3,
2019, ATC installed ORC socks in well GW02. On December 12, 2020, ATC replaced ORC
socks in wells GWO 1, GW02, GW04, GW05, and GW 14D. This report present the results of
groundwater monitoring conducted on December 12, 2019 to monitor ORC progress and
natural attenuation of residual impact at the site. Following the sampling event, new ORC
socks were installed. More details are provided in later sections of this report.
Groundwater Monitoring
On December 12, 2019, 13 site monitoring wells (GWO1, GW02, GW03A, GW04, GW05,
GW06, GW07, GW08, GW09D, GW 13D, GW 14D, GW 15, and GW 15D) were gauged for
depth to groundwater and samples collected for laboratory analyses. Monitoring wells GW 10,
GW 11, and GW 12 were intended for sampling but were dry and not sampled.
An oil/water interface probe was used to gauge each well. No light non -aqueous phase liquid
(LNAPL) was present. Since the nearby municipal water supply well (WSW) is not in
operation, ATC did not collect a WSW sample. Groundwater elevations were calculated
based on top of casing (TOC) elevations, which are referenced to an arbitrary on -site
benchmark of 100.00 feet above mean sea level. Well construction details for site monitoring
wells are summarized in Table 1. The locations of the monitoring wells are shown in Figure
2, and the groundwater elevation data are summarized in Table 2.
Based on the results of the December 2019, groundwater measurements, the groundwater
flow direction was generally to the south and southeast, consistent with previous site
information. A groundwater elevation contour map is included as Figure 3.
Upon completion of the well gauging activities, groundwater samples were collected from 13
site monitoring wells (GWO1, GW02, GW03A, GW04, GW05, GW06, GW07, GW08,
GW09D, GW 13D, GW 14D, GW 15, and GW 15D). Monitoring wells GW 10, GWII, and
GW 12 were unable to be sampled due to insufficient groundwater levels within the wells.
The groundwater samples were collected in laboratory supplied, preserved containers; placed
on ice; and shipped in accordance with chain -of -custody protocol to North Carolina -
accredited laboratory, SGS Acutest Laboratories, in Orlando, Florida. The groundwater
samples were analyzed by EPA Method 6200B for volatile organic compounds and also by
EPA Method 504.1 for 1,2-dibormoethane (EDB). The laboratory report for the December
2019, sampling event is included in Appendix A. Current groundwater analytical results are
summarized in Table 3, and historical groundwater analytical results are compiled in Table 4.
The groundwater analytical results were compared to the North Carolina 2L Standards and the
Gross Contamination Levels (GCLs). Groundwater analytical results indicate the following:
• The GCLs were not exceeded for any analyzed compound during the event;

NCDEQ Phillips 66 RM No. 2751
Ms. Trudy Beverly February 28, 2020
Incident: 14645 Page 3
• The groundwater samples collected from monitoring wells GW02 and GW 15D contained
benzene concentrations of 9.6 and 2.5 micrograms per liter (ug/L), respectively, exceeding
the North Carolina 2L Standard of 1.0 ug/L; and
• Other chemical constituents were detected in the sampled wells, however, at concentrations
below their respective 2L Standards.
ORC Installation
Following groundwater sample collection activities on December 20, 2019, ATC installed
)RC
socks in wells GWO1, GW02, GW-04, GWOS, and GW14D. Three socks were installed
in each well and were placed to bracket the groundwater column at the bottom of the well.
Conclusions
• The samples from monitoring wells GW02 and GW15D have benzene impact at
concentrations above the 2L Standard.
• Groundwater analytical results indicate that the ORC socks have contributed to a reduction in
petroleum hydrocarbon concentrations in site wells since 2018.
Based on the results of the December 2019, groundwater sampling event, ATC recommends
continued quarterly groundwater sampling events to monitor remedial progress of the
remedial socks and ongoing natural attenuation. Due to the benzene observed in well
GW 15D, ORC socks should be considered for this well.
