On September 6, 2023, a third-party tester discovered a line tightness failure corresponding to the 10,000-gallon premium underground storage tank (UST). A UST-17B form was filed with the North Carolina Department of Environmental Quality (NCDEQ), included as Attachment A. To determine if a release may have occurred to the environment, assessment activities were conducted as documented in this report. A soil boring log has been included as Attachment B, and the laboratory report for the samples collected during the site check has been included as Attachment C. One previous release has been associated with this site – Incident #42117 from September 2017 closed with no further action in August 2018. SITE ACTIVITIES Soil Sampling On September 20, 2023, AECOM met with Sweetwater Utility Exploration (Sweetwater) at the site to collect a soil sample – SB-1 near the 10,000-gallon premium spill bucket (Figure 2). Sweetwater air knifed the soil borings to a depth of approximately 3 feet below ground surface (bgs), then AECOM used a hand auger to collect the soil sample. The sample was collected at approximately 3 feet bgs and screened with a photoionization detector (PID). A soil boring log is included as Attachment B. AECOM bottled the sample for laboratory analysis for total petroleum hydrocarbons for gasoline range organics (TPH-GRO). The samples were submitted to Pace Analytical Services in Huntersville, North Carolina for analysis at the Huntersville, North Carolina laboratory. AECOM Page 2 RESULTS Based on laboratory analysis, the soil sample collected from SB-1 did not exceed the soil contamination action level established by NCDEQ. Laboratory analysis did not detect concentrations of TPH-GRO in sample SB-1. The laboratory report is included in Attachment C. CONCLUSIONS AND RECOMMENDATIONS Based on laboratory analysis of the soil sample collected near the 10,000-gallon premium UST spill bucket, no NCDEQ action levels were exceeded. AECOM, on behalf of Speedway recommends that this release be closed out with no further action. If you have any questions, please call Nicole Long, AECOM Project Manager, at (704) 649-6586.

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 EPA Method 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.
