(EnviroTrac), on behalf of Sunoco, Inc. (Sunoco), is pleased to present this report documenting monitoring activities performed at the Former Sunoco Bulk Terminal facility, located at 6900 West Market Street in Greensboro, Guilford County, North Carolina. In April 2010 Sunoco awarded an environmental services contract to EnviroTrac for continuing environmental services at this site. A USGS Topographic map is presented in Figure 1. This report presents the results of the semi-annual groundwater sampling activities conducted on May 25, 2017 and November 14, 2017. The approximate locations of the site groundwater monitoring wells are indicated in Figure 2. 1.1 Background According to NCDEQ, petroleum hydrocarbons were detected in the subsurface at the Astroline and Sunoco properties in 1986. At the time of the release, Sunoco owned the bulk storage terminal facility. Between 1986 and 1990, a groundwater quality investigation was performed at the site. In 1990, an Environmental Audit Agreement Report was submitted by ATEC Associates, Inc. (ATEC) to evaluate the site property. A Comprehensive Site Assessment was submitted by Matrix Environmental Technologies (Matrix) in April 1994. On May 16, 1994, Matrix submitted a CAP proposing a remediation system to address the absorbed phase and dissolved phase petroleum hydrocarbon contaminants at the subject site. On February 15, 1996, IT Corporation of North Carolina, Inc. (IT) submitted a CAP Addendum proposing the installation of a dual phase vapor extraction system (DPVE), in response to NCDEQ correspondence dated November 13, 1995. The DPVE system was installed from September to November 1996. The soil vapor extraction system was activated on January 10, 1997. The groundwater recovery and treatment system was activated on July 10, 1997, after the issuance of an NPDES permit. The system has remained off since August 1999 and a monitored natural attenuation program was implemented. An Annual Monitoring Report was submitted by IT on March 28, 2001. Sunoco has submitted Annual Monitoring Reports to NCDEQ for each year since 2002. Annual Groundwater Monitoring Report November 2017 Former Sunoco Bulk Terminal, Market Street, Greensboro, NC 2 2.0 GROUNDWATER MONITORING ACTIVITIES Groundwater monitoring activities were conducted on May 25, 2017 and November 14, 2017. Static groundwater levels were obtained from monitoring wells AW-1, AW-3, AW-4, AW-5, AW- 6, VEW-2, and VEW-4 prior to sample collection using an electronic oil/water interface probe to gauge water levels and measure the thickness of free product, if encountered, in site monitoring wells. A summary of well construction data is presented in Table 1. 2.1 Groundwater Elevation Monitoring Activities Liquid level readings were collected during the May 2017 and November 2017 sampling events using an electronic oil/water interface probe. The current and selected historical results of the gauging events are presented in Table 2. Free product was not detected during either sampling event. Groundwater elevation data obtained from the May 2017 sampling event and November 2017 sampling event was used to create groundwater elevation maps identified in Figure 3A and Figure 3B, respectively. The inferred shallow groundwater flow direction across the site is generally to the north. 2.2 Groundwater Sampling Activities May 2017 Groundwater samples were collected on May 25, 2017, from monitoring wells AW-1, AW-3, AW- 4, AW-5, AW-6, VEW-2, and VEW-4. Prior to sample collection, a minimum of three well casing volumes were purged from each well using a polyethylene disposable bailer. A groundwater sample was decanted from the bailer into laboratory supplied containers and placed on ice in a sample cooler. Groundwater samples from the May 2017 sampling event were shipped via overnight courier to Pace Laboratories in Huntersville, North Carolina for laboratory analysis by EPA Method 6200 including MTBE, IPE, and EDB. A summary of the laboratory analytical results for the May 2017 sampling event is presented in Table 3 and historical groundwater results are included in Table 4. A map showing the chemicals of concern in groundwater from the May 2017 sampling event is included in Figure 4A. Annual Groundwater Monitoring Report November 2017 Former Sunoco Bulk Terminal, Market Street, Greensboro, NC 3 November 2017 Groundwater samples were collected on November 14, 2017, from monitoring wells AW-1, AW- 3, AW-4, AW-5, AW-6, VEW-2, and VEW-4. Prior to sample collection, a minimum of three well casing volumes were purged from each well using a polyethylene disposable bailer. A groundwater sample was decanted from the bailer into laboratory supplied containers and placed on ice in a sample cooler. Groundwater samples from the November 2017 sampling event were shipped via overnight courier to Pace Laboratories in Huntersville, North Carolina for laboratory analysis by EPA Method 6200 including MTBE, IPE, and EDB. A summary of the laboratory analytical results for the November 2017 sampling event is presented in Table 3 and historical groundwater results are included in Table 4. A map showing the chemicals of concern in groundwater from the November 2017 sampling event is included in Figure 4B. Copies of the laboratory analytical reports for the May 25, 2017, and November 14, 2017 sampling events are included in Appendix A. In May 2017 benzene was detected above the NCDEQ Groundwater Quality 2L Standard (2L Standard) in monitoring wells AW-4, VEW-2 and VEW-4. MTBE was detected above the 2L Standard in VEW-2 and VEW-4. Naphthalene was detected above the 2L Standard in AW-4 and VEW-2. In November 2017, benzene was detected above the 2L Standard in monitoring well AW-4, VEW-2, and VEW-4. Naphthalene was detected above the 2L Standard in monitoring wells AW- 4 and VEW-2, and MTBE was detected above the 2L Standard in monitoring well VEW-2 and VEW-4. 3.0 CONCLUSION AND RECOMMENDATIONS 3.1 Conclusions Based on information collected during the May 2017 and November 2017 sampling events, the following conclusions were made: • Free product has not been detected on site since 2007 • Benzene was detected above the 2L Standard in monitoring wells AW-4, VEW-2 and VEW-4 in May 2017 • MTBE was detected above the 2L Standard in monitoring wells VEW-2 and VEW-4 in May 2017 Annual Groundwater Monitoring Report November 2017 Former Sunoco Bulk Terminal, Market Street, Greensboro, NC 4 • Naphthalene was detected above the 2L Standard in AW-4 and VEW-2 in May 2017 • Benzene was detected above the 2L Standard in well AW-4, VEW-2, and VEW-4 in November 2017 • MTBE was detected above the 2L Standard in well VEW-2 and VEW-4 in November 2017 • Naphthalene was detected above the 2L Standard in wells AW-4 and VEW-2 in November 2017 3.2 Recommendations It is our understanding that, effective January 2, 2016, NCDEQ implemented expansion of UST Risk-based Cleanup Standards to all petroleum releases. At this time, EnviroTrac proposes the completion and submission of a groundwater fate and transport model that will demonstrate that no significant risk is posed to health or the environment from the existing groundwater contaminant plume. Pending approval of the model, EnviroTrac will file a Notice of Residual Petroleum and deed restriction with the Guilford County Deed Registrar’s Office, and request a Status of No Further Action for this release.

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA Method 8260.
