Enaineerina License No. C-1598 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 Mr. Morris: Phillips 66 Company (Phillips 66) retained ATC Associates of North Carolina, P.C., (ATC) to provide 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 a single -story convenience store building and a 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 1 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 on behalf of Phillips 66, is submitting this report documenting sampling results for site monitoring wells subsequent to the installation of Regenesis ORC Advanced Filter Socks® (ORC socks). 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 Groundwater Standards (2L Standards; Title 15A, NCAC, Subchapter 2L, Part .0202). ORC socks were installed in well GW 14D due to a historical presence of MTBE at NCDEQ Mr. Brett Morris Phillips 66 RM No. 2751 April 16, 2019 Page 2 concentrations that were slightly below 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 March 26, 2019. Groundwater Monitoring On March 26, 2019, site monitoring wells GWO1, GW02, GW03A, GW04, GW05, GW06, GW07, GW 14D, GW 15 and GW 15D were gauged for depth to groundwater and checked for the presence of free product. An oil/water interface probe was used to gauge each well. 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 March 2019 groundwater measurements, the groundwater flow direction was generally to the south. A groundwater elevation contour map using the March 2019 gauging data is included as Figure 3. Upon completion of the well gauging activities, groundwater samples were collected from the site monitoring wells GWO1, GW02, GW03A, GW04, GW05, GW06, GW07, GW14D, GW15 and GW15D. 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), and naphthalene. Each sample was additionally analyzed by EPA Method 504.1 for ethylene dibromide (EDB) with low detection limits. The laboratory report for the March 2019 sampling event is included in Appendix A. Groundwater analytical results are summarized in Table 3, and historical groundwater analytical results are summarized in Table 4. The groundwater analytical results were compared to the North Carolina 2L Standard and North Carolina Gross Contamination Levels (GCLs). Groundwater analytical results indicate the following: • The groundwater sample collected from monitoring well GW02 contained a benzene concentration of 14.4 micrograms per liter (ug/L), exceeding the North Carolina 2L Standard; • Other chemical constituents were detected in the sampled wells, however, all were below their respective 2L Standards; NC 1'4 Mr. Brett Morris ?hiIlips 66 RM No. 2 J 5 April 16, 2019 Paee 3 Groundwater analytical results indicate that the MC socks have been successful in reducing petroleum hydrocarbon concentrations in site wells. Only well GW02 has petroleum concentrations (benzene) that exceed the 2L Standard. Based on the results of the March 2019 groundwater sampling event, ATC recommends that a groundwater monitoring event be conducted in June 2019 to allow the ORS socks installed in well GW02 to continue to remediate petroleum hydrocarbons in that area.
