Licensed Geologist North Carolina Seal No. 1338 Site Assessment Circle K No. 2723925 Matthews, North Carolina EXECUTIVE SUMMARY As required, the following executive summary provides the most pertinent information for this assessment. For additional information please refer to subsequent sections of this report.  ATC was contracted by Circle K on February 10 of 2023 to complete Site Assessment (SA) activities in response to the March 2022 release discovered during the underground storage tanks (USTs) removal activities. The services were provided in general accordance with the North Carolina Department of Environmental Quality (NCDEQ) “Guidelines for Assessment and Corrective Action for UST Releases” as required.  Previous assessments completed at the site include a UST Closure Report submitted on June 10, 2022 and a Phase I Limited Site Assessment Report submitted on November 1, 2022.  High levels of Benzene was discovered in monitoring well MW-1 which was installed as part of the LSA activities.  During CSA activities, an initial round of four monitoring wells (MW-2 through MW-4 and TW-1) were installed between February 15 and February 22, 2023. Soil samples collected from the borings indicated that soil contamination had been adequately defined in both the vertical and horizontal directions. Wells were sampled on March 8, 2023 and results indicated the groundwater plume had not been fully defined.  Primarily silt based soils were encountered on site, and partially weathered rock was encountered at a depth of approx. 50-feet below ground surface (BGS).  Groundwater flow at the site was determined to trend southward. The average hydraulic conductivity was calculated to be 0.32 feet/day and 1.1E-4 cm/sec in MW-1 and 0.46 feet/day and 1.6E-4 cm/sec in MW-3 with an average of 0.39 feet/day and 1.3E-4.  In conclusion, concentrations of various hydrocarbon constituents in the soil exceed their applicable Residential MSCCs standards. Additionally, dissolved phase levels of benzene were found to exceed the applicable GCLs were encountered in monitoring wells MW-1, MW-2, MW-3 and TW-1. Therefore based on this information, we recommend further assessment for the release associated with the former UST.

The Circle K 27203925 facility is located at 100 East John Street in Matthews, Mecklenburg County, North Carolina (henceforth referred to as the “site” or “subject facility”). Summaries of UST system and owner/operator information is included in Table 1 and Table 2. A site vicinity map with topographic features is included as Figure 1. Circle K Store No. 2723925 is no longer being operated as a convenience store or gas station. It is an abandoned property, and is currently for lease. During the recent CSA activities, the site is developed with one (1) one-story building and car-wash. Site monitoring wells are illustrated on Figure 2. These assessment activities were conducted in response to the results of the “Phase I Limited Site Assessment” dated November 1, 2022 in accordance with the Pre-Approval Task Authorization (PATA) number 48574-1 dated February 10, 2023. Site Assessment Circle K No. 2723925 Matthews, North Carolina 2.0 SITE DESCRIPTION 2.1 Site Characterization A release was of detected on the site on February 2, 1998 and assigned incident #3592 with Unocal listed as the responsible party. Semi-annual groundwater sampling took place on the site in the late 1990s due to the release. An air sparging remediation system was also used on the site to help reduce the contamination of the soil and groundwater on the site. A letter of No Further Action was issued for the site on October 15, 1998. The former Circle K No. 2723925 facility, located at 100 East John Street in Matthews, Mecklenburg County, North Carolina, is currently a vacant gas station. One single-story convenience store. Two 12,000-gallon, one 10,000-gallon gasoline UST, and one 2,000-gallon diesel UST, associated product lines, piping, and dispensers were removed in March 2022. The USTs, product lines, piping, and dispensers were owned by Circle K. UST system information is included in Table 1. Pertinent site features are depicted on Figure 2. 2.2 Surrounding Property Use At the time of this assessment, East John Street adjoined the site to the north with commercial development to the north. South Trade Street adjoined the site to the west with commercial development. Land to the south and east was developed with commercial and residential properties. The zoning status of the site is commercial, and the surrounding area is zoned commercial and residential. 2.3 Site History In 2022, Circle K retained ATC to complete closure activities associated with the removal of the USTs, dispensers, and associated product piping. UST closure activities were conducted in March 2022, and consisted of subcontractor oversight and limited soil sampling in the vicinity of the former UST system. The collected soil samples contained detectable concentrations of Total Petroleum Hydrocarbons (TPH) Gasoline Range Organics (GRO) and Diesel Range Organics and various VOCs contaminants were all detected above state 2L Standards. In August 23, 2022, ATC collected soil sample and installed a monitoring well in with a LSA due to the high Benzene levels identified during the UST removal. During the LSA, soil and groundwater concentrations of Benzene were detected above the State GCL cleanup levels. 2.4 Site and Regional Geology According to the 1985 “Geologic Map of North Carolina”, the site is located in the Charlotte and Milton Belts. Subsurface lithology in this region consists of intrusive granites, part of the Churchland Plutonic Suite and Mooresville intrusives characterized as megacrystic to equigranular. Soils encountered during sampling activities and the installation of monitoring well MW-1 consisted of clay to approximately 16 feet below ground surface (ft-bgs), silty micaceous fine sand to approximately 26 ft-bgs, and sandy silt to approximately 34 ft-bgs. Site Assessment Circle K No. 2723925 Matthews, North Carolina 3.0 SENSITIVE RECEPTOR INFORMATION 3.1 Water Supply Wells According to the Comprehensive Site Assessment completed for Incident #3592 by S&ME for Unocal in June 1994, no water supply wells were noted within 1,500-feet of the site. 3.2 Public Water Supply Municipal water is generally supplied to the site and surrounding area by Mecklenburg County Public Utilities. During the visual reconnaissance, ATC observed water meters and fire hydrants in the search area and within 500 feet of the site. 3.3 Surface Water ATC reviewed a USGS 7.5-Minute (Figure 1) to identify surface water bodies in the site vicinity. In addition, ATC conducted a visual reconnaissance for surface water bodies in the area. Four Mile Creek is located approximately 1,000 feet south of the site. 3.4 Wellhead Protection According to the Division of Water Quality Wellhead Protection Website, the site is not located within a wellhead protection program area. 3.5 Deep Aquifers in the Coastal Plain The risk classification criteria specified in Title 15A NCAC 2L .0115(d) requires an evaluation for the presence of unconfined or semi-confined deep aquifers in the Coastal Plain region which may be used as a source of drinking water. The site is not located in the Coastal Plan Physiographic region. 3.6 Subsurface Structures Prior to drilling activities, ATC contacted One-Call of North Carolina to locate publicly owned underground utilities at the site. ATC also subcontracted with a private utility locator to identify privately owned utilities and UST system components at the site. Public and private underground utilities (electric, communications, water) were located on-site prior to conducting subsurface work. ATC does not expect that the utilities would intersect the water table at the site based on the measured depth to water in well MW-1. 3.7 Land Use The subject site is located within the city limits of Matthews, in Mecklenburg County, North Carolina. The site is accessible from East John Street to the north and South Trade Street to the west. The site is developed with one vacant single-story convenience store. Surface cover at the site is primarily concrete with some grass and landscaped areas along the edges of the property. Adjoining properties are generally commercial and residential. Site Assessment Circle K No. 2723925 Matthews, North Carolina 3.8 Risk Characterization In accordance with 15A NCAC 2L .0115, a completed Limited Site Assessment Risk Classification and Land Use Form provided by the NCDEQ is included in Appendix A. Answers and explanations included on the form are based on information obtained by ATC during LSA activities. 4.0 Comprehensive Site Assessment In conducting the SA activities at the site, the following summarizes details and provides required information pertaining to the SA activities conducted at the subject facility during both UST abandonment and LSA activities. 4.1 Soil Assessment Activities During UST closure assessment activities, Zebra Environmental was contracted to remove the USTs, associated piping, and dispensers from the site. Eleven soil samples were collected from the bottom of the UST excavation, eighteen soil samples were collected from the product lines in 10-foot intervals, and at any observed connection points. Soil samples collected from the UST excavations were taken directly from the bucket of the excavator. Soil samples collected from the product lines and dispenser islands were collected directly from the sidewalls of the excavation trench. All samples were collected utilizing new disposable nitrile gloves during to reduce the overall risk of cross contamination. Soil samples were placed into sealable Zip-loc® bags with the required volume for laboratory analysis being placed in laboratory provided bottle-ware. Soil samples were submitted for analysis by TPH – GRO and/or DRO. Laboratory results from product lines and dispenser islands indicated that UST-B2, USC-G1, UST-C2, UST-C3, USTD-1, and USTD-2 had detections above State Action Levels for TPH-DRO and TPH-GRO. Four samples were collected for Risk Based analysis of EPA Method 8260, 8270, MADEP VPH and EPH. Samples from USTC-2, USTD-2, and DIS-1 all had various detections above Soil-to- Groundwater MSCCs, and above Residential MSCCs for Volatile Organic Compounds (VOC) EPA Method 8260, MADEP EPH and VPH. TL-12 had no detections above Soil-to-Groundwater MSCCs, Residential, or Industrial MSCCs. On August 23, 2022, ATC supervised the installation of a soil boring and soil sample collection by Environmental Drilling and Probing Services (EDPS) a North Carolina-licensed well driller. Soil samples were collected directly into macro-core samplers at intervals of five foot until moist to wet soil was encountered at a depth of approximately 20 ft-bgs A portion of each sample was placed into a sealable air-tight bag and allowed time to volatilize prior to being screened in-field for the presence of volatile organic compounds using a photo-ionization detector (PID) calibrated to 100- parts per million (ppm) Isobutylene. The soil sample with the highest PID readings were collected for laboratory analysis from depth interval of 15 – 20 ft-bgs. The soil sample was analyzed for volatile organic compounds (VOCs) by EPA Method 8260D, semi-volatile organic compounds (SVOC) by EPA Method 8270E, Massachusetts Department of Environmental Protection (MADEP) volatile petroleum hydrocarbons (VPH), and MADEP extractable petroleum hydrocarbons (EPH). The soil samples were delivered to Waypoint Analytical Services, a North Carolina Certified laboratory, in Charlotte, North Carolina. Soil analytical results were compared to the Soil-to-Groundwater Maximum Soil Contaminant Concentrations (MSCCs), and Residential and Industrial/ Commercial cleanup levels. Based on Site Assessment Circle K No. 2723925 Matthews, North Carolina the laboratory report, various contaminates exceeded the Soil to Groundwater MSCCs Standards at various depths. No exceedances were above the Residential and Industrial/Commercial MSCCs Standards. On February 15 and 21, 2023 ATC supervised the installation of monitoring wells MW-2 through MW-4 and TW-1. Soil samples were collected for Total Petroleum Hydrocarbon Diesel Range Organics (TPH-DRO) and Total Petroleum Hydrocarbon Gasoline Range Organics (TPH-GRO) during the installation of wells MW-2 through MW-4 and TW-1 at various depths by Environmental Drilling and Probing Services (EDPS) a North Carolina-licensed well driller. Soil analytical results were compared to the Soil-to-Groundwater Maximum Soil Contaminant Concentrations (MSCCs), and Residential and Industrial/ Commercial cleanup levels. Based on the laboratory report, Diesel and Gasoline Range Organics were detected above State Target Cleanup Levels. A summary of soil analytical data is provided in Table 3. 4.3 Groundwater Assessment Activities A total of twelve (5) monitoring wells were installed at the site during various phases of assessment. Monitoring well MW-1 was installed on August 23, 2022 during Limited Site Assessment (LSA) activities. Monitoring wells MW-2 through MW-4 and TW-1 were installed between February 15 and 22, 2023 these SA activities. A summary of well construction information is included as Table 5. Type II monitoring well borings (MW-1 through MW-4) were completed utilizing either a Geoprobe® 7822DT drill-rig using 4¼-inch inner diameter hollow-stem augers. Type III monitoring well borings (TW-1) was completed utilizing a Canterra CT450 drill rig using 8¼-inch inner diameter hollow-stem augers for the outer casing followed by air rotary technology utilizing a 6-inch air hammer for the inner casing. Wells were constructed of a 2-inch nominal diameter schedule 40 polyvinyl chloride (PVC) riser and either 10 or 15-feet of schedule 40 PVC well screen with 0.010-inch slots. A No. 2 sand filter pack was employed to fill the annulus of the borehole to depths of approximately 2-feet above the tops of the well screens. Approximately 2-feet of bentonite chips were emplaced into the borehole annulus on top of the sand filter pack and subsequently hydrated with clean, potable water. The remainder of the borehole annulus was filled with a neat cement mixture to the surface. Due to the high traffic nature of the well locations, the wells were each completed with flush-mounted traffic bearing well covers installed in a 2-foot by 2-foot concrete pad. Following installation, the newly installed monitoring wells were developed by surging and pumping using a submersible pump, decontaminated between each well. The driller’s well construction logs are included as Appendix A. Site Assessment Circle K No. 2723925 Matthews, North Carolina Groundwater samples were collected from the monitoring wells over the course of consecutive phases of assessment. The wells were purged prior to sample collection using new, disposable polyvinyl chloride bailers, while wearing new, disposable nitrile gloves. Purging was accomplished by removing a minimum of three well volumes while monitoring in-field groundwater quality parameters for stabilization, or until the well was bailed dry and allowed to recharge. Ground water samples collected were placed into laboratory provided sample containers, sealed and labeled, and placed into an ice-filled cooler for preservation at a temperature of approximately 4° Celsius. Following completion of sampling activities, samples were submitted under chain-of- custody protocol to Wayoint Analytical Laboratory for analysis of select volatile organic compounds (VOCs) by EPA Method 6200B. 4.4 Groundwater Analytical Results During the initial site assessment activities MW-1 was sampled on September 26, 2022 The groundwater analytical results were compared to 2L Standards and GCLs. Groundwater analytical results indicated the following:  LNAPL was not observed.  Benzene exceeded target GCLs.  Various constituents exceeded state 2L Standards ON March 8, 2023 wells MW-1 through MW-4 and TW-1 were sampled. The groundwater analytical results were compared to 2L Standards and GCLs. Groundwater Analytical results indicated the following:  LNAPL was not observed.  Benzene exceeded target GCLs.  Various constituents exceeded state 2L Standards A summary of the analytical results are represented in Table 4. Laboratory analytical report is located in Appendix B. 4.5 Hydrogeologic Investigation During SA activities on March 8, 2023, two rising-head slug tests were performed in Type II monitoring wells MW-1 and MW-3. Data acquisition was accomplished through the use of a Level TROLL 700 transducer and data logger. Data was downloaded for interpretation using Win-Situ 5 and evaluated with AQTESOLV software, as developed by HydroSOLVE, Inc. As previously stated Groundwater flow at the site was determined to trend southward. The average hydraulic conductivity was calculated to be 0.32 feet/day and 1.1E-4 cm/sec in MW-1 and 0.46 feet/day and 1.6E-4 cm/sec in MW-3 with an average of 0.39 feet/day and 1.3E-4. Slug test results are included in Appendix C. Site Assessment Circle K No. 2723925 Matthews, North Carolina 5.0 Conclusions and Recommendations During SA activities at the site in March 2023, three Type II monitoring wells (MW-2 through MW- 4) and one Type III monitoring well (TW-1) were installed at the site to delineate the hydrocarbon plume. Monitoring well termination depths ranged from 30-feet BGS to 50-feet BGS. Soil samples collected during the installation of monitoring wells MW-2 through MW-4 and TW-1 indicated that the vertical contamination extended to the groundwater table. The SA activities indicate that the horizontal plume has migrated offsite towards the south of the site. Elevated concentrations of Benzene and other constituents above 2L standards at locations of monitoring wells MW-1, MW-2, MW-3, and TW-1 are attributed to the former Circle K property. Based on the direction of groundwater flow, Benzene plume has slowly migrated off site and towards the south adjacent properties. Dissolved-phase contamination appears to be adequately delineated to the north, east, and west. The plume appears to be following the groundwater flow path towards the south. Additional assessment would be required to determine the most effective method of corrective action. A 96-hour Mobile Multi-Phase Extraction (MMPE) is recommended using MW-1, MW-2, and MW- 3 as extraction wells and re-sampling all site wells after the MMPE event is recommended for the site. 6.0 Limitations This report has been prepared for the exclusive use of Circle K Stores Inc. for specific application to the referenced site in Matthews, North Carolina. The assessment was conducted based on the scope-of-work and level of effort requested by the NCDEQ and with resources adequate only for that scope-of-work.

The above referenced project has been analyzed per your instructions. The analyses were performed in accordance with the applicable analytical method. The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule May 2021) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance. The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as-received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to the samples included in this report.

The above referenced project has been analyzed per your instructions. The analyses were performed in accordance with the applicable analytical method. The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule May 2021) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance. The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as-received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to the samples included in this report. Please do not hesitate to contact me or client services if you have any questions or need additional information.
