Site Map – Sample Locations Appendices Appendix A: UST-2 and UST-3 Forms Appendix B: UST Disposal Manifest Appendix C: Laboratory Analytical Results Introduction This report summarizes the tank closure and initial site assessment activities for the removal of three underground storage tanks (USTs) at the former Joyce’s Nantahala Convenience Store located at 1370 US Highway 19 in Topton, Macon County, North Carolina. The USTs were owned by Noonday Springs, LLC. and have been in temporary closure since December 31, 2004. Figure 1 shows the site location on a USGS topography map, and Figure 2 presents a site map showing the location of the former USTs and corresponding soil sampling locations. Site History The following tables summarize information about the USTs at the site: Tank No. Volume Contents Tank Material Use Date last used removed or closed in permanent closure release detected? 1 6000 Diesel Steel STIP 3 Resale 12/31/2004 Removed 5/9/23 No 2 6000 Gas Steel STIP 3 Resale 12/31/2004 Removed 5/9/23 No 3 6000 Gas Steel STIP 3 Resale 12/31/2004 Removed 5/9/23 No Ownership of Tanks: Noonday Springs, LLC. 4030 Wake Forest Rd, Ste 349 Raleigh, NC 27609 Telephone: (616) 889-9288 Brief Description of the Site Land use at the site is commercial and the surrounding properties are low density residential. The closest surface water body is a raised fish hatchery pond located approximately 65 feet to the northwest and is fed by a PVC pipe from Rowlin Creek located approximately 140 feet to the northwest. Rowlin Creek is located at an approximately 16 feet lower elevation than the top of the USTs. Groundwater and bedrock were not encountered during the UST removal activities. Closure Procedures On May 9, 2023, the tank removal activities commenced. The USTs were located to the west of the dispensers as shown in Figure 2. Since the USTs have been in temporary closure since 2004, the tanks were completely empty and dry on the inside. The LELs inside the USTs were reading below 5% without the need for dry ice. The USTs were removed using a 160 series excavator. Soil samples were collected at the fill ports and beneath the USTs. Soil samples were also collected underneath the product lines and dispensers. The soil samples were analyzed for Gasoline Range Organics (GRO) underneath the two gasoline USTs, fill ports, and the two gasoline dispensers; and GRO and Diesel Range Organics (DRO) underneath the diesel UST, fill port, product lines, and the diesel dispenser. The USTs were transported to Mountain Metals for recycling. Soil analytical results are summarized in Tables 1 and corresponding soil sampling locations can be found in Figure 2. Source Investigation Fourteen soil samples were collected underneath the UST system located at the site (Figure 2). Three soil samples were collected underneath the dispensers (D-1, D-2, and D-3) at a depth of approximately 2 ft-bls. Three soil samples (FP-1, FP-2, and FP-3) were collected immediately underneath each fill port at a depth of approximately 2 ft-bls. Six soil samples were collected underneath the USTs (T-1 through T-6) at a depth of 12 ft-bls. Two soil samples (L-1 and L-2) were collected underneath the product lines at a depth of approximately 3 ft-bls. Each soil sample was collected by filling an EPA and NCDEQ approved soil container while wearing a new pair of disposable nitrile gloves. The soil samples were put on ice and transported to Pace Analytical in Asheville, North Carolina for analysis using EPA Method 8015C for GRO and DRO when required for diesel items. • Analytical results did not detect any compounds exceeding the NC action limits for GRO and DRO in any of the samples analyzed at the site. Soil analytical results are summarized in Table 1. A copy of the laboratory analytical report is included in Appendix C. Initial Abatement Activities Due to the absence of soil contamination (PID results) at the site, no initial abatement actions were initiated. Conclusions and Recommendations On May 9, 2023, Petroleum Specialty, Inc. and Singleton Environmental, Inc. removed three USTs located at the site. No soil contamination was observed during the removal activities and no soil contamination was discovered in the laboratory analysis for the soil samples collected at the site. Therefore, Singleton Environmental recommends no further action due to the absence of soil contamination resulting from the UST system being removed from the site.

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 - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. 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 EPAMethod 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited.
