Ground Water Monitoring Report Prepared on: May 17, 2023 Nic’s Pic Kwik #4 Project Manager: William Regenthal, P.G. GRI Project No. 3024 ii EXECUTIVE SUMMARY Nic’s Pic Kwik #4 is located at 564 N. Patterson Street in Maxton, Robeson County, North Carolina. The site is currently owned by Quality Oil Company and is operated by Nic’s Pic Kwik as a convenience store and petroleum retail facility. A release was documented during a Site Check conducted in June 2008. There are two 6,000-gallon gasoline, one 4,000-gallon gasoline, one 8,000-gallon diesel, one 4,000-gallon diesel and one 4,000-gallon kerosene USTs currently in use at the site with ten associated dispenser islands. The adjoining properties are a mixture of single family residential and commercial properties. According to the information determined during receptor survey activities, no potable water supply wells were identified within 1,000 feet of the site. Public water is available to the site and surrounding properties within a 1,500-foot radius of the site. On February 26, 2019, during annual compliance testing activities, a non-passing spill bucket was reported for the 8,000-gallon diesel UST. A site check was conducted on September 4, 2019, confirming a release at the 8,000-gallon UST spill bucket. The release was assigned incident number 42236. The contaminant plumes for Incident Numbers 29522 and 42236 are commingled, and Incident Number 42236 was closed by NCDEQ in January 2020. A MMPE event was conducted from March 6 to March 10, 2023, at the site on monitoring wells MW-7, MW-16 and RW-1. A total of 1,890 gallons of affected ground water was recovered during the MMPE event. No measurable liquid free product was recovered during this MMPE event. The average fluid recovery rate was 19.69 gallons per hour. Based on mass-removal calculations an additional 99.58 pounds or 167.50 gallons of vapor phase hydrocarbons were removed at an average rate of 1.74 gallons per hour. On April 25, 2023, two monitoring wells (MW-7 and MW-16) and one recovery well (RW-1) were gauged, purged and sampled. Concentrations of requested method constituents that exceeded the MACs were reported in the ground water samples collected from MW-7, MW-16 and RW-1. The concentration of benzene reported in MW-16 exceeded the GCL. Contaminant mass at the site has decreased by 68% since the July 2020 sampling event Based on this information, the risk classification for the site should remain intermediate risk. It appears that the MMPE event was successful in removing vapor-phase hydrocarbons from the site. The MMPE event likely drew contaminants from beneath the dispenser island into the extraction wells. Additional AFVR or MMPE events should be conducted at the site in order to continue to recover free product and reduce the contaminant mass at the site. Semi-annual ground water monitoring should be continued at the site until ground water concentrations decrease to less than the GCLs. Following the continued reduction of contaminant mass in the vicinity of MW-7 and MW-16, a Feasibility Study for the use of continued ground water extraction and/or the introduction of surfactant injection could be completed. ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc.

Ground Water Monitoring Report Prepared on: May 17, 2023 Nic’s Pic Kwik #4 Project Manager: William Regenthal, P.G. GRI Project No. 3024 1 1.0 SITE HISTORY AND CHARACTERIZATION GRI presents the results of the April 2023 ground water sampling event at the Nic’s Pic Kwik #4 site; located at 564 N. Patterson Street in Maxton, Robeson County, North Carolina (Figure 1). These activities were conducted in accordance with GRI Proposal No. 23-248, which was submitted to NCDEQ on April 12, 2023, and was approved as Task Authorization No. 29522-21, on April 13, 2023. State correspondence has been included as Appendix A. The site is currently owned by Quality Oil Company and is operated by Nic’s Pic Kwik as a convenience store and petroleum retail facility. There are two 6,000-gallon gasoline, one 4,000-gallon gasoline, one 8,000-gallon diesel, one 4,000-gallon diesel and one 4,000-gallon kerosene USTs currently in use 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 are a mixture of single family residential, and commercial properties. The site contains two buildings (the store and a car wash) and is primarily capped with concrete and asphalt. The overall topography at the site is relatively flat. A site compliance inspection conducted on January 18, 2006, found that the site’s USTs were not being operated in compliance with North Carolina rules and statutes. A NORR dated February 12, 2007, required the existing USTs be abandoned or internally inspected to determine compliance. The tanks were internally inspected on February 28, 2007, and found to have pits and holes. The tanks were reportedly repaired and re-lined. In accordance with a NOV dated December 27, 2007, Environmental Hydrogeological Consultants (EHC) conducted a Site Check on June 9, 2008. Results indicated a release ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc. Ground Water Monitoring Report Prepared on: May 17, 2023 Nic’s Pic Kwik #4 Project Manager: William Regenthal, P.G. GRI Project No. 3024 2 had occurred at the site. EHC completed a LSA on November 30, 2009. The receptor survey conducted as part of the LSA did not identify any water supply wells within 250 feet of the source area and identified three non-potable water supply wells within 1,500 feet of the site. Municipal water is available to properties in the area. The site was classified as intermediate risk based on groundwater contamination exceeding GCLs. A CSA was completed by Environ-Pro, P.C. on June 5, 2014. A Site Map showing the locations of the monitoring wells and the structures on-site has been included as Figure 2. A total of sixteen Type II monitoring wells (MW-1 through MW-16) and one Type III monitoring well (DW- 1) were installed at the site during previous ground water assessment activities. Three 96-hour MMPE events and three 8-hour AFVR events were conducted at the site between December 2014 and March 2023, to reduce dissolved contaminant concentrations in site ground water, as well as vapor-phase hydrocarbons in soil at the site. Annual compliance testing activities on February 26, 2019, identified a non-passing spill bucket associated with the 8,000-gallon diesel UST. A site check was completed by GRI on September 4, 2019, which confirmed a release had occurred at the diesel spill bucket. The release was assigned the incident number 42236. The contaminant plumes for Incident Numbers 29522 and 42236 are commingled, and Incident Number 42236 was closed by NCDEQ in January 2020. 2.0 PRESENTATION OF CURRENT SITE ASSESSMENT INFORMATION/ COMPARISON TO HISTORICAL ASSESSMENT INFORMATION On April 25, 2023, two Type II monitoring wells (MW-7 and MW-16) and one recovery well (RW-1) were gauged, purged and sampled in accordance with NCDEQ guidelines. Depths to ground water in the Type II monitoring wells ranged from 4.53 feet to 4.60 feet below the tops of well casings. Ground water elevations in the Type II monitoring wells relative to a temporary benchmark with an assumed datum of 100.00 feet ranged from 94.51 to 95.64 feet. Ground water flow direction and horizontal hydraulic gradient were not calculated during the April 2023 sampling event. Historically, ground water flow was generally toward the northeast. Well construction and gauging information is presented in Table 3. A Water Table Surface Map based on the Type II monitoring wells is included as Figure 3. A summary of the current ground water gauging data is shown below: Well ID Screened Interval (x to y ft. BGS) Bottom of Well (ft. BGS) Top of Casing Elevation (ft.)

Concentrations of individual BTEX constituents, MTBE, naphthalene, TAA, TAME, TBA, n-propylbenzene, 1,2,4- trimethylbenzene and/or 1,3,5-trimethylbenzene that exceeded the MACs were reported in the ground ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc. Ground Water Monitoring Report Prepared on: May 17, 2023 Nic’s Pic Kwik #4 Project Manager: William Regenthal, P.G. GRI Project No. 3024 3 water samples collected from MW-7, MW-16 and RW-1. The concentration of benzene reported in MW- 16 exceeded the GCL. A summary of the analytical results for ground water samples collected on April 25, 2023, is presented in Table 4. A Ground Water Quality Map based on the April 2023 data is included as Figure 4. A complete report of laboratory analyses of the ground water samples collected from the monitoring wells during the April 2023 sampling event has been included as Appendix B. A summary of the current ground water analytical data is shown below: Contaminant of Concern → Be n z e n e To l u e n e Et h y l b e n z e n e Xy l e n e s MT B E Na p h t h a l e n e Well ID MACs (mg/l) 1 600 600 500 20 6 GCL (mg/l) 5,000 260,000 84,500 85,500 20,000 6,000 MW-7 4,500 7,580 898 7,750 514 579 MW-16 11,000 17,800 1,720 8,510 1,130 326 RW-1 3,060 4,640 708 3,540 416 178 The baseline contaminant mass at the site was determined based on the total benzene, toluene, ethylbenzene, xylenes, MTBE and naphthalene concentrations from the July 2020 ground water sampling event. The contaminant plume consists of one area (Area 1) based on the benzene concentrations during the July 2020 ground water sampling event. The contaminant mass has been reduced by 67.8% in Area 1 since July 2020. Contaminant mass calculations have been included as Appendix C. A map of the contaminant mass areas has been included as Figure 5. A chart depicting the overall declining trend in contaminant mass is shown below: ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc. Ground Water Monitoring Report Prepared on: May 17, 2023 Nic’s Pic Kwik #4 Project Manager: William Regenthal, P.G. GRI Project No. 3024 4 A CSA was completed in June 2014. A CAP has not been developed for this incident. The site is located in the Coastal Plain Physiographic Province of North Carolina. The water table has a seasonal high depth to water of approximately 3 to 11 feet bgs. 3.0 FREE PRODUCT REMOVAL No free product was observed during the April 2023 groundwater sampling event. A MMPE event was conducted from March 6 to March 10, 2023, at the site on monitoring wells MW-7, MW-16 and RW-1. A total of 1,890 gallons of affected ground water was recovered during the MMPE event. No measurable liquid free product was recovered during this MMPE event. The average fluid recovery rate was 19.69 gallons per hour. Based on mass-removal calculations an additional 99.58 pounds or 167.50 gallons of vapor phase hydrocarbons were removed at an average rate of 1.74 gallons per hour. 4.0 NATURAL ATTENUATION / NATURAL SOURCE ZONE DEPLETION STATUS Due to the site being in an active assessment phase, no natural attenuation monitoring plan is currently in place at the site. A CAP has not yet been developed for this incident. The site risk classification is currently ranked as intermediate since benzene concentrations remain above the GCL in MW-16. If contaminant concentrations are reduced to less than the GCLs, then the site risk classification can be lowered. ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc. Ground Water Monitoring Report Prepared on: May 17, 2023 Nic’s Pic Kwik #4 Project Manager: William Regenthal, P.G. GRI Project No. 3024 5 The contaminant mass at the site was reduced by 0.4% following the completion of the MMPE event in March 2023. However, approximately 167.50 gallons of vapor-phase hydrocarbons were removed during the March 2023 MMPE event. It appears that the MMPE event drew contaminants from beneath the dispenser island into the extraction wells. Additional recovery wells could be installed within the benzene GCL contaminant plume to continue to maximize the reduction of vapor-phase hydrocarbons in the soil in the vicinity of the dispensers. Significant reductions in the benzene concentrations and the removal of free product should occur prior to the implementation of surfactant injection or the introduction of other contaminant reducing media. Once contaminant concentrations are significantly reduced, only then will injection be a viable remedial option for this incident. A Feasibility Study exploring the above referenced remedial options should be conducted. 5.0 CONCLUSIONS  On April 25, 2023, a ground water sampling event was conducted. Two monitoring wells and one recovery were gauged, purged and sampled.  Concentrations individual BTEX constituents, MTBE, naphthalene, TAA, TAME, TBA, n- propylbenzene, 1,2,4-trimethylbenzene and/or 1,3,5-trimethylbenzene that exceeded the MACs were reported in the ground water samples collected from MW-7, MW-16 and RW-1.  A concentration of benzene that exceeded the GCL was reported in the ground water sample collected from MW-16.  The contaminant mass has been reduced by 67.8% in Area 1 since July 2020. Contaminant mass at the site was reduced by approximately 0.4% following the completion of the March 2023 MMPE activities  The March 2023 MMPE event removed approximately 167.50 gallons of vapor-phase hydrocarbons from the extraction wells and surrounding soil.  Based on this information, the risk classification for the site should remain intermediate risk. It appears that the MMPE event was successful in removing vapor-phase hydrocarbons from the site. The MMPE event likely drew contaminants from beneath the dispenser island into the extraction wells. Additional AFVR or MMPE events should be conducted at the site in order to continue to recover free product and reduce the contaminant mass at the site. Semi-annual ground water monitoring should be continued at the site until ground water concentrations decrease to less than the GCLs. Following the continued reduction of contaminant mass in the vicinity of MW-7 and MW-16, a Feasibility Study for the use of continued ground water extraction and/or the introduction of surfactant injection could be completed. 6.0 LIMITATIONS This report has been prepared for the exclusive use of Quality Oil & Gas Company and the NCDEQ for specific application to the referenced site in Robeson County, North Carolina.
