Engineering License No. C-1598 November 21, 2019 Ms. Trudy Beverly North Carolina Department of Environmental Quality Mooresville Regional Office Division of Waste Management - Underground Storage Tank Section 610 East Center Avenue, Suite 301 Mooresville, North Carolina 28115 Re: Groundwater Monitoring Update Letter Report Circle K Store No. 8387 Phillips 66 Company RM No. 2751 8425 Highway 49 North Mt. Pleasant, Cabarrus County, North Carolina 28124 Facility ID No. 0-004529 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 Ms. Trudy Beverly November 21, 2019 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; NCDEQ Ms. Trudy Beverly Incident: 14645 Phillips 66 RM No. 2751 November 21, 2019 Page 3 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.
