Ground Water Monitoring Report Prepared on: December 23, 2022 Former OM Mart Project Manager: William Regenthal GRI Project No. 5685 ii EXECUTIVE SUMMARY Former OM Mart is located at 113 West Main Street in Biscoe, Montgomery County, North Carolina. The site is currently owned by VISHALP, LLC and is operated by Quality Oil & Gas as a petroleum retail facility, tire service and convenience store. A site check was conducted in November 2011 following a failed line test that confirmed the presence of a release. Currently, one 6,000-gallon gasoline, two 4,000-gallon gasoline, one 2,000-gallon gasoline USTs, one kerosene AST, associated dispensers and product piping are active at the site. The site contains one building 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. A Phase I LSA was conducted in January 2008 by a past consultant. There are four unused/irrigation wells within 1,000 feet of the site. The Town of Biscoe well identified during January 2008 receptor survey activities is reportedly out of service and has been capped off. Municipal water serves all properties within 1,000 feet of the site. Based on this information and the past presence of ground water contamination exceeding the GCLs, the site risk ranking is intermediate. On November 16, 2022, two Type II monitoring wells (MW-12 and MW-13) were installed off-site to total depths of 35 feet BGS, with screened intervals of 15 feet, each. On November 16, 2022, twelve Type II monitoring wells were gauged, purged and sampled in accordance with NCDEQ guidelines. Concentrations of individual BTEX constituents, MTBE, naphthalene, TAA, TAME, bromodichloromethane, TBA, chloroform, 1,2 dichloroethane, isopropylbenzene, di-isopropyl ether, n- propylbenzene, IPE, chlorobenzene, methyl chloride, p-dichlorobenzene, methylene chloride, 1,2,4- trimethylbenzene and/or 1,3,5-trimethylbenzene that exceeded the MACs were reported in the ground water samples collected from MW-1, MW-2, MW-5 and MW-7 through MW-12. The concentrations of benzene reported in the ground water samples collected from MW-1, MW-7, MW-8 and MW-9 exceeded the GCLs. The November 16, 2022, sampling event will be used as the baseline for future contaminant mass calculations. Based on this information, the risk classification for the site should remain intermediate risk. The ground water contaminant plume is reasonably defined for an intermediate risk site. Prior to developing a CAP for this site, soil sampling should be conducted in the area of MW-1, MW-7, MW-8 and MW-9 to determine the vertical and horizontal extent of soil contamination. Semi-annual ground water monitoring should be continued at the site in order to establish contaminant mass trends. The next sampling event is tentatively scheduled for May 2023. ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc.

Broad Avenue Rockingham, NC 28379 Re: Acknowledgement of Report Receipt OM Mart (former) 113 West Main Street Biscoe, Montgomery County Incident Number: 29478 Risk Classification: Intermediate Ranking: I-180-A Dear Mr. McDonald: The UST Section, Division of Waste Management, Fayetteville Regional Office, is in receipt of the Ground Water Monitoring Report dated May 12, 2022. The UST Section agrees with the recommendation for continued quarterly ground water monitoring in advance of preparation of a Comprehensive Site Assessment Report. However, this office requests that you also include off-site MW-4 & MW-6 for at least the next sampling event. The requested lab method 6200B should include Ethanol plus Oxygenates. The next sampling event is anticipated for July 2022 with the data presented in the Monitoring Report format during August 2022. Also, because this parcel was sold during July 2019 and ground water contamination has not been remediated to below “unrestricted use standards”, you were required by the North Carolina General Statute (NCGS) 143B-279.9 and 143B-279.11 to file a Notice of Residual Petroleum (Notice) with the Register of Deeds in Montgomery County and then to submit a certified copy of the filed Notice to the Fayetteville Regional Office. This task should be completed as soon as possible to get into compliance with NCGS 143B-279.9 and 143B-279.11. If you have questions, please contact me at the Fayetteville Regional Office address below or at (910) 433-3347. Sincerely, Kenneth E.
