Ground Water Monitoring Report Prepared on: April 6, 2023 Former Roseboro BP Project Manager: Rae Troiano Brown, P.G. GRI Project No. 2059 ii EXECUTIVE SUMMARY Former Roseboro BP is located at 270 E. Dr. Martin Luther King Jr. Blvd. in Roseboro, Sampson County, North Carolina. The site is currently owned by William H. Owen and is operated by Xpress Car Wash. In 1991, a UST release at the site was discovered during repairs to a public water line located along the north side of North Carolina Highway 24. In November 1993, a vacuum extraction and air sparging system was installed at the site that operated until October 1996 when the site priority ranking was lowered by the NCDEQ and the cleanup was suspended. No USTs have been operated at the site since 2003. The adjoining properties are a mixture of residential and commercial properties. A municipal water supply well (WSW-7) for the Town of Roseboro is located approximately 1,600 feet from the site. All structures within 1,000 feet of the source area are serviced by a municipal water supply system. The site was ranked high risk because of the municipal water supply well. In January 2010, a second plume on the Roseboro BP site was reported. However, no definitive evidence exists that the free product from the Roseboro BP release migrated off site, and ground water contamination reported in adjacent property wells may be from the EPCO 3-Way Food Mart release. In 2014, petroleum constituent concentrations which exceeded MCCs in soil samples collected at depths of 4 – 5 feet BGS were reported at the EPCO Food Mart in the Phase I and Limited Phase II Environmental Site Assessment report (depths to water were 10 feet BGS). In the 2015 Site Check report, EPCO MW-103 (which is located down-gradient of the EPCO UST basin) reported a concentration of benzene of 4,400 g/L. On February 14, 2023, seven Type II monitoring wells (MW-20, MW-22, MW-35, MW-43, MW-44, EPCO- MW-101, and EPCO-MW-102) and one telescoping well (DMW-3) were gauged, purged, and/or sampled. MW-2R had an obstruction at approximately 4.86 feet below TOC and neither a depth-to-water measurement nor a ground water sample could be collected. Free product was measured in monitoring wells EPCO-MW-101 and EPCO-MW-102 located at the EPCO 3-Way Food Mart. Ground water samples were collected from MW-20, MW-22, MW-35, MW-43, MW-44, and DMW-3. Contaminant concentrations in water samples collected from MW-43 and MW-44 exceeded the MACs. All of the reported contaminant concentrations were below the GCLs. An estimated concentration of MTBE not exceeding the MAC was reported in the ground water sample collected from WSW-7. The total contaminant mass at the site has decreased by 60.4% since 2015. No free product has been reported at the site since 2009. No contaminant concentrations have exceeded GCLs since 2019. Based on this information, the site risk should be reduced to low; and, subsequent to filing a notice of residual petroleum and completing public notice, the incident should be closed. ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc.

Ground Water Monitoring Report Prepared on: April 6, 2023 Former Roseboro BP Project Manager: Rae Troiano Brown, P.G. GRI Project No. 2059 1 1.0 SITE HISTORY AND CHARACTERIZATION GRI presents the results of the February 2023 ground water sampling event at the Former Roseboro BP site, located at 270 E. Dr. Martin Luther King Jr. Blvd. in Roseboro, Sampson County, North Carolina (Figures 1, 2, 3, and 3A). These activities were conducted in accordance with GRI Proposal No. 22-884, which was submitted to NCDEQ on January 11, 2023, and was approved as Task Authorization No. 6601- 45 on January 12, 2023. State correspondence is included as Appendix A. The site is currently owned by William H. Owen and is operated by Xpress Car Wash. In 1991, a release at the site was discovered during repairs to a public water line located on-site along the north side of North Carolina Highway 24. Subsequent tightness testing of the on-site UST system indicated that the release was from a premium unleaded gasoline product line. In November 1993, a vacuum extraction and air sparging system was installed at the site that operated until October 1996 when the site priority ranking was lowered by the NCDEQ and the cleanup was suspended. No USTs have operated at the site since 2003. 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 residential and commercial properties. The site contains one building (car wash) and is primarily capped with concrete and asphalt. The overall topography at the site is relatively flat. Twenty-six Type II monitoring wells, six Type III monitoring wells, and four recovery ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc. Ground Water Monitoring Report Prepared on: April 6, 2023 Former Roseboro BP Project Manager: Rae Troiano Brown, P.G. GRI Project No. 2059 2 wells were installed during previous ground water assessment activities. A Site Map showing the locations of the monitoring wells has been included as Figure 3 and a detailed Site Map is included as Figure 3A. Historical cross-sections that include soil data and estimated contaminant contours are included as Appendix B. A municipal water supply well (WSW-7) for the Town of Roseboro is located approximately 1,600 feet from the site. All structures within 1,000 feet of the source area are serviced by a municipal water supply system. Adjacent property owner information and well owner information is presented in Tables 3 and 4, respectively. In the 2004 CAP, three phases were proposed. In Phase I, water supply wells were to be abandoned and MMPE events were to be implemented as necessary to remove free product and reduce dissolved phase contaminant concentrations. A six-month monitoring program was to be conducted with monthly analysis of the municipal well and quarterly analysis of the monitoring wells. In Phase II, packer tests were to be conducted on the municipal well to determine permanent placement for uncontaminated ground water zone. A similar monitoring program to the first phase was to be implemented. If the first and second phases failed, in the Phase III, a granular activated carbon filtration system would be installed to reduce contaminant concentrations to applicable standards. A long-term sampling program would be required to monitor the plume migration and potential carbon breakthrough. Please note that the CAP was not implemented; and, therefore, no milestones have been established for the site. In 2003, all the USTs were removed from the Roseboro BP site. In January 2010, a second plume on the Roseboro site was reported. However, no definitive evidence exists that the free product found in monitoring wells (MW-101 and MW-102) on the adjacent property, EPCO 3-Way Food Mart, originated from Roseboro BP. Monitoring wells EPCO-MW-101 and EPCO-MW-102 were installed as part of the EPCO 3-Way Food Mart site assessment. Two monitoring wells (MW-43 and MW-44) were installed at Roseboro BP site to evaluate whether or not free product present at the Roseboro BP site could have migrated offsite. Historic gauging of MW-43 and MW-44 has not detected free product. Free product in MW-2R at the Roseboro BP site has not been present since 2009. In 2002, USTs were installed at EPCO 3-Way Food Mart and no release was reported to the NCDEQ at the time of installation. Therefore, if the former air sparge system at the Roseboro BP site which operated from 1993 to 1996 “pushed” free product onto the EPCO 3-Way Food Mart site, then the free product would have been discovered during the UST installation. Petroleum constituent concentrations which exceeded MCCs in soil samples collected at depths of 4 – 5 feet from the EPCO 3-Way Food Mart site were reported in a EPCO Food Mart Phase I and Limited Phase II Environmental Site Assessment report ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc. Ground Water Monitoring Report Prepared on: April 6, 2023 Former Roseboro BP Project Manager: Rae Troiano Brown, P.G. GRI Project No. 2059 3 (December 28, 2014); depth to ground water is typically 10 – 12 feet below ground surface. In addition, in the Site Check Report (February 26, 2015) for the EPCO 3-Way Food Mart property, EPCO MW-103 (which is located down-gradient of the EPCO 3-Way Food Mart UST basin) reported a concentration of benzene of 4,400 g/L and the hydraulic gradient reported was 0.00091 feet per foot which is extremely flat and undoubtedly subject to lithologic heterogeneities. This evidence would indicate that the free product on the EPCO 3-Way Food Mart property could be originating from a release on the EPCO 3-Way Food Mart property. Please note that some of the information contained in this report was obtained under the supervision of Clark Environmental Services, Inc. (Clark), the previous consultant on the project until GRI was retained in March 2004. Although GRI cannot verify the accuracy of their information, for the purpose of this report it is assumed to be correct, and any inferences or interpretations made by GRI based on data that may be incorrect are not the responsibility of GRI. Please refer to earlier submittals for additional information regarding assessment activities. In January 2022, GRI conducted an updated receptor survey. All structures within 1,000 feet of the source area are serviced by a municipal water supply system. No surface water bodies were identified within a 500-foot radius of the site. Adjacent property owner information is shown on Table 3 and water supply well information is shown on Table 4. Potable well locations are shown on Figure 2. 2.0 PRESENTATION OF CURRENT SITE ASSESSMENT INFORMATION/ COMPARISON TO HISTORICAL ASSESSMENT INFORMATION On February 14, 2023, seven Type II monitoring wells (MW-20, MW-22, MW-35, MW-43, MW-44, EPCO- MW-101, and EPCO-MW-102) and one telescoping well (DMW-3) were gauged, purged, and/or sampled. Free product was measured in monitoring wells EPCO-MW-101 (0.04 feet) and EPCO-MW-102 (0.36 feet) located at the EPCO 3-Way Food Mart site. MW-2R had an obstruction at approximately 4.86 feet below TOC and neither a depth-to-water measurement nor a ground water sample could be collected. Depths to ground water in the Type II monitoring wells ranged from 11.97 feet to 14.71 feet below TOC. Ground water elevations in the Type II monitoring wells ranged from 116.01 to 113.69 feet. Ground water flow was generally to the northeast with a horizontal gradient of approximately 0.01 feet per foot. The vertical gradient between paired wells MW-35 and DMW-3 was approximately 0.024 feet per foot in the downward direction. Well construction and gauging information is presented in Table 5. A Water Table Surface Map based on the Type II monitoring wells is included as Figure 4.

Concentrations of benzene, toluene, xylenes, MTBE, naphthalene, TAA, n-propylbenzene, and/or 1,2,4- trimethylbenzene reported in the ground water samples collected from MW-43 and MW-44 exceeded the MACs. All of the reported contaminant concentrations were below the GCLs. An estimated concentration of MTBE not exceeding the MAC was reported in the ground water sample collected from WSW-7. A summary of the analytical results for ground water samples collected on February 14, 2023 is presented in Table 6. A summary of the MNA parameter readings collected from each of the sampled monitoring wells is presented in Table 7.

A theoretical contaminant mass area was calculated around MW-2R, MW-43, and MW- 44 and used in the contaminant mass calculations. The total contaminant mass at the site has decreased 60.4% since 2015. Please note that since MW-2R was not sampled during this event, only the contaminant concentrations of MW-43 and MW-44 were used for the February 2023 contaminant mass calculations. Contaminant mass calculations are included as Appendix D. A map of the contaminant mass areas is included as Figure 6. A chart depicting the overall trend in contaminant mass is shown below: The site is located in the Coastal Plain Physiographic Province of North Carolina.

In 2004, a three phase CAP was proposed. Please note that the CAP was not implemented; and, therefore, no milestones or natural attenuation plan has been established. 5.0 CONCLUSIONS  the Former Roseboro BP is operated by Xpress Car Wash. In 2003, all the USTs were removed from the Roseboro BP site.  On February 14, 2023, seven Type II monitoring wells and one telescoping well were gauged, purged, and/or sampled. MW-2R had an obstruction at approximately 4.86 feet below TOC and neither a depth-to-water measurement nor a ground water sample could be collected.  Free product was measured in monitoring wells EPCO-MW-101 (0.04 feet) and EPCO-MW-102 (0.36 feet). Free product at the EPCO 3-Way Food Mart should not be attributed to Roseboro BP and should be the responsibility of EPCO 3-Way Food Mart.  Ground water elevations in the Type II monitoring wells ranged from 116.01 to 113.69 feet. Ground water flow was generally to the northeast with a horizontal gradient of approximately 0.01 feet per foot. The vertical gradient between paired wells MW-35 and DMW-3 was approximately 0.024 feet per foot in the downward direction.  The concentrations of benzene, toluene, xylenes, MTBE, naphthalene, TAA, n-propylbenzene, and/or 1,2,4-trimethylbenzene reported in the ground water samples collected from MW-43 and MW-44 exceeded the MACs. All of the reported contaminant concentrations were below the GCLs.  A theoretical contaminant mass area was calculated around MW-2R, MW-43, and MW-44 and used in the contaminant mass calculations. The total contaminant mass at the site has decreased 60.4% since 2015.  An estimated concentration of MTBE not exceeding the MAC was reported in the ground water sample collected from WSW-7.  No USTs have operated at the site since 2003. According to the updated receptor survey conducted in January 2022, all structures within 1,000 feet of the source area are serviced by a municipal water supply system. No free product has been reported at the site since 2009. No contaminant concentrations have exceeded GCLs since 2019. Based on this information, the site risk should be reduced to low; and, subsequent to filing a notice of residual petroleum and completing public notice, the incident should be closed. 6.0 LIMITATIONS This report has been prepared for the exclusive use of Wellman Oil Company, Inc. for specific application to the referenced site in Sampson County, North Carolina.

Dr. Martin Luther King Jr. Blvd. Roseboro, Sampson County Incident Numbers: 6601 Risk Classification: Intermediate Ranking: H 151 D Dear Mr. Owen: The Underground Storage Tank Section of the Division of Waste Management has reviewed the Groundwater Monitoring Report dated March 31, 2022. The report will be maintained in the Fayetteville Regional Office. We generally concur with the recommendations provided in the reviewed report. The following are provided for your consideration; • The most recent Risk Ranking Assessment for incident #6601 was performed in April 2018. At that time, the risk assigned for incident #6601 was high. Pursuant to Title 15A NCAC 2L .0407(a) you have a continuing obligation to notify the Department of Environmental Quality of any changes that might affect the risk or land use classifications that have been assigned. • The data selected for the contaminant mass calculations and graph do not utilize data for all dates available for MW-2R, MW-43, and MW-44 between December 2015 and January 2022, and do not present compound specific contaminant mass calculations reflecting 2L exceedances. In addition, a historical contaminant concentration vs. time vs. groundwater graph was not provided. The contaminant mass calculations should be amended and both graphs included in future reports. • A file review of available reporting for this site and the adjacent downgradient facility, incident #29932, has been performed. Work conducted by Clark Environmental Services between 1991 and 1994 included downgradient wells MW-13, MW-14, and MW-15, as well as a former vacuum sparge system, active between 1993 and 1996. These features were located along the western property boundary of the present day EPCO 3-Way Food Mart prior to the initial development of the property in approximately 1999. The file indicates plume migration to the EPCO 3-Way Food Mart from an upgradient source and is available for review. 2059 Received APR 11 2022 North Carolina Department of Environmental Quality | Division of Waste Management Wilmington Regional Office | 127 Cardinal Drive Extension | Wilmington, NC 28405 | (910) 796-7215 • The recommended annual groundwater sampling should include MW-2R, MW-20, MW-22, MW-35, MW-43, MW-44, EPCO-101, EPCO-102, DMW-3, and WSW-7. Depth to product/water measurements should be collected from MW-2R, MW-20, MW-22, MW-35, MW- 43, MW-44, EPCO-101, and EPCO-102 at the time of sampling. The next annual groundwater monitoring event should be scheduled for January 2023.
