Ground Water Monitoring Report Prepared on: November 5, 2020 Speedway #7940 Project Manager: Joanna Alley, E.I.T. GRI Project No. 4764 ii EXECUTIVE SUMMARY Speedway #7940 is located at 5729 West Friendly Avenue in Greensboro, Guilford County, North Carolina. The site is currently owned by WILCOHESS, LLC and is operated by Speedway, LLC as a petroleum retail facility. The surrounding properties are commercial, residential, office and public/institutional. According to the information determined during receptor survey activities, two non-potable water supply wells were identified within a 1,500 -foot radius of the site; one of which is within 250 feet. Public water is available to the site and surrounding properties within a 1,500-foot radius of the site. No surface water bodies were identified within a 500-foot radius of the site. Currently, three 8,000-gallon gasoline, one 8,000-gallon kerosene and one 8,000-gallon diesel USTs are in use at the site. The site is covered by concrete and asphalt. On March 25, 2018, two non-passing spill bucket integrity tests were reported and on April 9, 2018, GRI conducted a site check at the subject site. No free product was noted at the site. The RAL and/or soil-to-water MCCs were below the concentrations of GRO, benzene, toluene, ethylbenzene and/or xylenes reported in the soil samples collected from SB-1 and SB-2. Limited Site Assessment activities were conducted between November 2018 and February 2019. The results from the February 13, 2019 sampling event indicated that the GCL was below the concentration of MTBE in MW-4. A comprehensive site assessment was recommended. On October 15, 2020, four Type II monitoring wells (MW-1 through MW-4) were gauged, purged and sampled. Groundwater flow was generally to the northwest with a horizontal gradient ranging between 0.043 and 0.008 feet per foot. The MACs were below the concentrations of benzene, toluene, ethylbenzene, xylenes, MTBE, naphthalene, isopropylbenzene, n-propylbenzene, 1,2,4-trimethylbenzene, and/or 1,3,5-trimethylbenzene reported in the ground water samples collected from MW-1 through MW- 4. No reported contaminant concentrations exceeded the GCLs. Based on this information, the risk classification for the site should remain intermediate risk, and additional ground water sampling should be conducted to determine if contaminant concentrations continue to be below GCLs or if the reported concentrations were affected by the higher water table. ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc.

GRI Project No. 4764 1 1.0 SITE HISTORY AND CHARACTERIZATION Geological Resources, Inc. (GRI) presents the results of the October 2020 ground water sampling event at the Speedway #7940 site; located at 5729 West Friendly Avenue in Greensboro, Guilford County, North Carolina (Figure 1). These activities were conducted in accordance with GRI Proposal No. 20-479, which was submitted to the North Carolina Department of Environmental Quality (NCDEQ) on August 27, 2020, and was approved as Task Authorization No. 45028-003 on September 1, 2020. State correspondence has been included as Appendix A. The site is currently owned by WILCOHESS, LLC and is operated by Speedway, LLC as a petroleum retail facility. The site is located in the Charlotte and Milton Belt Physiographic Province of North Carolina, based on the Geologic Map of North Carolina of 1985. On March 25, 2018, two non-passing spill bucket integrity tests were reported, and on April 9, 2018, GRI conducted a site check at the subject site. Currently, three 8,000-gallon gasoline, one 8,000-gallon diesel and one 8,000-gallon kerosene USTs are active at the site. UST owner/operator information and UST system information are included as Tables 1 and 2, respectively. The Registered Tank Report is shown below: The site and surrounding area is a mixture of residential, public/institutional, and commercial properties. The site contains one building and one fuel canopy, and is primarily capped with concrete and asphalt. The overall topography at the site is relatively flat. No surface water bodies were identified within a 500- foot radius of the site. Four Type II monitoring wells (MW-1 through MW-4) were installed at the site during previous assessment activities. A Site Map showing the locations of the monitoring wells and the structures on-site has been included as Figure 2. On November 28, 2018, GRI personnel conducted a receptor survey at the site. Two non-potable water supply wells were identified within a 1,500-foot radius of the site. Of the two non-potable water supply wells, one water supply well was identified within a 250-foot radius of the site. Public water is available to the subject site and to all surrounding properties.

NATIONWIDE.GLOSSARY OF TERMS Guide to Reading and Understanding Your Laboratory Report The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description J4 The associated batch QC was outside the established quality control range for accuracy. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Geological Resources- NC Speedway 4764 L1274669 10/29/20 11:48 24 of 28 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Geological Resources- NC Speedway 4764 L1274669 10/29/20 13:28 24 of 28 ONE LAB.
