Report Editor ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc. Limited Site Assessment Report Prepared on: February 17, 2023 Home Race Mart #1 Project Manager: Ethan Rogerson, GIT GRI Project No. 5836 i EXECUTIVE SUMMARY The Home Race Mart #1 site is located at 7824 Seven Springs Highway in Nakina, Columbus County, North Carolina. The property operates as a petroleum retail facility and convenience store. The site is covered by concrete, asphalt and grass. There are one 12,000-gallon compartmentalized gasoline (8,000-gallon and 4,000-gallon compartments), one 6,000-gallon diesel and one 2,000-gallon off-road diesel USTs currently in use at the site with six associated dispenser islands. On October 21, 2021, two soil sample (SS-PREM-2' and SS-ORDSL-2’) were collected at the 4,000-gallon gasoline and 2,000-gallon off-road diesel spill buckets, respectively. Concentrations of TPH-GRO and TPH- DRO that exceeded the RALs were reported in soil sample SS-ORDSL-2’. No free product was noted at the site. Site Check results identified a release at the site and a LSA was required. On November 21, 2022, a receptor survey was conducted. Three potable water supply wells and five non- potable water supply wells were identified within a 1,500-foot radius of the site. One non-potable water supply well was identified within a 250-foot radius of the site. Public water is available to the subject site and the surrounding properties. No surface water bodies were identified within a 500-foot radius of the site. On November 21, 2022, one monitoring well (MW-1) was installed directly adjacent to the diesel UST basin. During the installation of MW-1, soil sample (MW-1 (5’)) was collected at 5 feet BGS and submitted for laboratory analyses of VOCs using EPA Method 8260B, semi-VOCs using EPA Method 8270B and VPH/EPH by the MADEP Methods. All reported contaminant concentrations were less than the Soil-to- Water MCCs. On November 21, 2022, a ground water sample was collected from MW-1. The ground water sample was submitted for laboratory analyses of VOCs by EPA Method 602, semi-VOCs using EPA Method 625 + 10 highest tentatively identified compounds, EDB by EPA Method 504.1, lead by 6010C and MADEP VPH/EPH. A concentration of lead that exceeded the MACs was reported in the ground water sample collected from MW-1. All contaminant concentrations were less than the GCLs. On January 30, 2023, water samples were collected from potable water supply wells WSW-5 and WSW-6. The water supply well samples were submitted for laboratory analyses of VOCs by EPA Method 602, semi- VOCs by EPA Method 625+ 10 highest tentatively identified compounds, EDB by EPA Method 504.1, lead by 6010C and MADEP VPH/EPH. All contaminant concentrations were less than the MACs and GCLs. Based on these results no further assessment is warranted. The concentration of lead is not associated with the diesel spill bucket release and incident 48187 should be closed. ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc.

The water main and other underground utilities run along 7 Creeks Highway and several underground utility lines were observed on the property. 7. Property Owners and Occupants: The names and addresses of the owners of properties adjacent to the site are presented in Table 4. Property boundaries are shown on Figure 2. Property cards for the adjacent property owners are attached as Appendix A. 3. SITE GEOLOGY AND HYDROGEOLOGY According to the 1985 Geologic Map of North Carolina, the site is located in the Waccamaw Formation. The Waccamaw Formation consists of bluish-gray to tan, loosely consolidated fossiliferous sand with silt ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc. Limited Site Assessment Report Prepared on: February 17, 2023 Home Race Mart #1 Project Manager: Ethan Rogerson, GIT GRI Project No. 5836 5 and clay. The formation straddles the Pleistocene-Pliocene boundary. On November 21, 2022, one monitoring well (MW-1) was installed directly adjacent to the diesel UST basin. The soil sample collected during the well installation was a brown silty clay mix. The depth to ground water during the November gauging event was 4.06 feet below the top of well casing. Copies of the well construction record and subsurface log are included as Appendix B. A Site Map showing the location of MW-1 is included as Figure 3. Well construction and gauging information is presented in Table 5. A photo of MW-1 is shown below: 4. SITE INVESTIGATION On October 21, 2021, GRI performed a site check that included collecting soil samples at the 4,000-gallon gasoline compartment and 2,000-gallon off-road diesel spill buckets, respectively. Soil samples SS-PREM- 2' and SS-ORDSL-2’ were each collected at depths of approximately 2 feet bgs. The concentrations of GRO and DRO reported in soil sample SS-ORDSL-2' exceeded the RALs. On November 21, 2022, a receptor survey was conducted. Three potable water supply wells and five non- potable water supply wells were identified within a 1,500-foot radius of the site. One non-potable water supply well was identified within a 250-foot radius of the site. Public water is available to the subject site and the surrounding properties. No surface water bodies were identified within a 500-foot radius of the site. During the installation of MW-1, one soil sample (MW-1 (5’)) was collected at 5 feet BGS and submitted ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc.

On November 21, 2022, a ground water sample was collected from MW-1. The ground water sample was submitted for laboratory analyses of VOCs by EPA Method 602, semi-VOCs by EPA Method 625 + 10 highest tentatively identified compounds, EDB by EPA Method 504.1, lead by 6010C and MADEP VPH/EPH. On January 30, 2023, water samples were collected from potable water supply wells WSW-5 and WSW-6. The water supply well sample was submitted for laboratory analyses of VOCs by EPA Method 602, semi- VOCs by EPA Method 625 + 10 highest tentatively identified compounds, EDB by EPA Method 504.1, lead by 6010C and MADEP VPH/EPH. 1.

Quality Control: The soil and ground water samples were immediately placed in laboratory-supplied containers after collection, which were then placed in iced coolers. New disposable bailers were used to sample the monitoring well and new nitrile gloves were worn during soil and ground water sampling. Samples were logged using proper chain-of-custody procedures. The samples were transported to a North Carolina certified laboratory for analysis. A laboratory supplied trip blank was included in the sample cooler. No detectable concentrations of requested method constituents were reported in the trip blank. 5. CONCLUSIONS AND RECOMMENDATIONS  The site is an active convenience store and petroleum retail facility. Land use in the area consists of commercial, residential, office and public/institutional properties.  November 21, 2022, a receptor survey was conducted on. Four potable water supply wells and four non-potable water supply wells were identified within a 1,500-foot radius of the site. One potable water supply well was identified within a 250-foot radius of the site. Public water is available to the subject site and the surrounding properties. No surface water bodies were identified within a 500-foot radius of the site.  On November 21, 2022, one monitoring well (MW-1) was installed directly adjacent to the diesel UST basin. During the installation of MW-1, one soil sample (MW-1 (5’)) was collected at 5 feet BGS. All reported contaminant concentrations were less than the Soil-to-Water MCCs.  On November 21, 2022, a ground water sample was collected from MW-1. A concentration of lead that exceeded the MACs was reported in the ground water sample collected from MW-1. All contaminant concentrations were less than the GCLs.  On January 30, 2023, water samples were collected from potable water supply wells WSW-5 and WSW-6. All reported contaminant concentrations were less than the MACs and GCLs.  Based on these results no further assessment is warranted. The concentration of lead is not associated with the diesel spill bucket release and incident 48187 should be closed. 6.
