NCDEQ Incident No. 14645
Risk Classification: High (380D)
ATC Project No. P662751014
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 remediation wells is included as Figure 2.
ATC is pleased to submit this report documenting sampling results for site monitoring wells to
monitor the results of prior 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 GW01, GW04, GW05 and GW 14D on
January 5, 2018. Previous groundwater monitoring events had indicated the presence of ethylene
dibromide (EDB) in wells GW0l, GW04 and GW05 at concentrations slightly 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

NCDEQ Phillips 66 RM No. 2751

Incident: 14645 Page 2
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. This report present the results of groundwater monitoring conducted on August 22, 2019,
to monitor ORC progress and natural attenuation of residual impact at the site.
Groundwater Monitoring
On August 22, 2019, 16 site monitoring wells (GWO1, GW02, GW03A, GW04, GW05, GW06,
GW07, GW08, GW09D, GW 10, GW 11, GW 12, GW 13D, GW 14D, GW 15, and GW 15D) were
gauged for depth to groundwater and checked for the presence of free product prior to sample
collection. An oil/water interface probe was used to gauge each well. No free product was
present. Since the nearby municipal water supply well (WSW) is not in operation, ATC did not
collect a WSW sample. Groundwater elevations were then calculated based on top of casing
(TOC) elevations, which are referenced to an arbitrary on -site benchmark of 100.00 feet. 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 August 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 16 site
monitoring wells (GWO1, GW02, GW03A, GW04, GW05, GW06, GW07, GW08, GW09D,
GW 10, GW 11, GW 12, GW 13D, GW 14D, GW 15, and GW 15D). 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 including the following petroleum constituents: benzene,
toluene, ethylbenzene, total xylenes (BTEX), methyl tertiary butyl ether (MTBE), isopropyl ether
(IPE), ethylene dibromide (EDB) and naphthalene. The laboratory report for the August 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;
• The groundwater sample collected from monitoring well GW02 contained a benzene
concentration of 6.2 micrograms per liter (ug/L), exceeding the North Carolina 2L
Standard of 1.0 ug/L;
• Other chemical constituents were detected in the sampled wells, however, at
concentrations below their respective 2L Standards;

Groundwater analytical results indicate that the ORC socks have been successful in reducing
petroleum hydrocarbon concentrations in site wells. The sample from monitoring well
GW02 has benzene impact at a concentrations above the 2L Standard.
Based on the results of the August 2019, groundwater sampling event, ATC recommends
installation of new ORC socks in wells GWO1, GW02, GW04, GW05, and GW14D (3 socks in
each well) and quarterly groundwater sampling events to monitor remedial progress of the
remedial socks and ongoing natural attenuation.
