The monitoring event was conducted on June 17, 2024. Figure 1 is a portion of the 2017 Lidar Hillshade with topographic contours and depicts the site location and vicinity with relevant topographic features. Figure 2 is a site map showing the UST field and monitoring well locations on a 2019 aerial image basemap. The site is located on the north side of Amboy Road in an area of commercial and residential development. Site History During a routine site inspection conducted in 2009, a release from the diesel dispenser was detected. Soil samples collected indicated total petroleum hydrocarbons as diesel and gasoline range organics (TPH-DRO/GRO) at a concentration of 669 milligrams per kilogram (mg/kg) and 374 mg/kg, respectively. The Site Check Report was submitted (by others) to The North Carolina Department of Environmental Quality (NCDEQ) in December 2009. Impacted soil associated with the diesel fuel dispenser was subsequently excavated in August 2011 and post excavation samples indicated no analytes in excess of the soil to water maximum contaminant concentrations (MSCCs). The Initial Abatement Action Report was submitted to NCDEQ in October 2011. In September 2011 a leak was detected in the 8,000-gallon gasoline underground storage tank (UST). As part of the initial abatement activities, the UST was pumped out and repaired. Subsequent assessment activities included the installation of on-site monitoring wells and sampling. Monitoring wells MW-1, MW-3, and MW-5 historically contained free phase product and four aggressive fluid vapor recovery events (AFVR) were conducted between December 2012 and May 2013 removing approximately 1,742-gallons of product. The following assessment reports have been submitted (by others) to NCDEQ in relation to the gasoline release at the Eblen Short Stop #2 • 20-Day Report – October 2011 • Initial Abatement Action Report (IAAR) – June 2014 • Limited Site Assessment Report (LSA) – August 2014 • Comprehensive Site Assessment Report (CSA) – October 2016 • Groundwater Monitoring Report – April 10, 2019 • Groundwater Monitoring Report – November 13, 2019 • Groundwater Monitoring Report – April 13, 2020 • Groundwater Monitoring Report – November 30, 2020 • Groundwater Monitoring Report – August 23, 2022 • Groundwater Monitoring Report – April 12, 2023 • Groundwater Monitoring Report with MMPE – January 30, 2024 Groundwater Monitoring Report Eblen Short Stop #2 Asheville, North Carolina 2 On July 24, 2019, a Notice of Violation letter was issued by NCDEQ indicating that the diesel dispenser (9/10) did not have a proper spill containment bucket installed. Therefore, Biltmore Oil Company contracted Mountain Environmental to perform site check activities. On August 6, 2019, Mountain Environmental personnel visited the subject site with Biltmore Oil personnel in order to perform site check soil sampling activities. According to Biltmore Oil personnel, dispenser 9/10, which did not contain proper spill containment, was the stand-alone diesel fuel dispenser. One soil sample (DISP-1) was collected immediately underneath the fuel dispenser utilizing a stainless-steel hand auger. The soil sample was collected at approximately 1.5-2 feet below ground surface (bgs) and submitted to Pace Analytical for analysis of total petroleum hydrocarbons – gasoline range organics (GRO) and diesel range organics (DRO). Laboratory results indicate that the sample contained TPH-DRO at a concentration of 741 mg/kg and TPH-GRO at a concentration of 464 mg/kg. Both the TPH-DRO and TPH-GRO concentrations exceed the NCDEQ Cleanup Level of 100 mg/kg and 50 mg/kg, respectively indicating a reportable release has occurred. On October 17, 2019, Mountain Environmental Services, Inc. performed additional site check activities. Due to the elevated TPH-DRO/GRO levels, an additional soil sample was collected underneath the stand-alone diesel dispenser in the same location as the August 2019 sampling. The additional soil sample D-1 was submitted to Pace Analytical for analysis of Risk-Based Parameters. This included volatile organic compounds (VOCs) by EPA Method 8260, semi-volatile organic compounds (SVOCs) by EPA Method 8270, and MADEP Methods for extractable and volatile petroleum hydrocarbons (MADEP-EPH/VPH). According to the laboratory analytical report total C9-C22 aromatics exceeded the soil-to-groundwater maximum contaminant concentrations (MSCCs). No analytes exceeded the residential or industrial/commercial MSCCs. The Site Check Report was submitted to NCDEQ on November 13, 2019. The following table summarizes information about USTs at this site: Tank No. Volume (gallons) Contents (i.e., gasoline, diesel, kerosene, heating oil, waste oil, Use (resale, heating building, distribution, farm or residential, etc.) Date last used Indicate whether UST has been removed or closed in place Date of permanent closure (if applicable) Was a release detected from this UST system? If yes, give Groundwater Monitoring Report Eblen Short Stop #2 Asheville, North Carolina 3 The following table summarizes information about ASTs at this site: Tank No. Volume (gallons) Contents (i.e., gasoline, diesel, kerosene, heating oil, waste oil, Use (resale, heating building, distribution, farm or residential, etc.) Date last used Indicate whether UST has been removed or closed in place Date of permanent closure (if applicable) Was a release detected from this UST system? If yes, give Free Phase Product Monitoring wells MW-1, MW-3, and MW-5 have historically contained free phase product and four aggressive fluid vapor recovery events (AFVR) were conducted between December 2012 and October 2019 removing approximately 1,767-gallons of product. During the August 2022 sampling event, free product was detected in monitoring wells MW-1 and MW-5 at a thickness of 0.10 feet and 0.11 feet, respectively. Approximately 2-gallons of product and liquid was bailed from each monitoring well (MW-1 and MW-5). Absorbent socks were subsequently placed in each well. During the February 2023 sampling event, free product was detected in monitoring wells MW-1 and MW-5 at a thickness of 0.21 feet and 0.43 feet, respectively. Approximately 5-gallons of product and liquid were bailed from each monitoring well (MW-1 and MW-5) and absorbent socks were subsequently replaced in each well. During the August 2023 sampling event, free product was detected in monitoring wells MW-1 and MW-5 at a thickness of 0.80 feet and 0.30 feet, respectively. Approximately 5-gallons of product and liquid were bailed from each monitoring well (MW-1 and MW-5) and absorbent socks were subsequently replaced in each well. A mobile multi-phase extraction event (MMPE) was conducted between December 18-22, 2023. Prior to the MMPE free product was detected in monitoring wells MW-1 and MW-5 at a thickness of 0.73 feet, 0.28 feet, respectively. During the event, SEI was able to evacuate approximately 3,600 gallons of contaminated groundwater. Based on total emission calculations, the event removed approximately 264.698 pounds (or 42.35 gallons) of petroleum product and vapor from beneath the site. During the June 2024 monitoring event absorbent socks were removed from MW-3 and replaced in monitoring wells MW-1 and MW-5. The spent absorbents were transported to Biltmore Oil Groundwater Monitoring Report Eblen Short Stop #2 Asheville, North Carolina 4 Company and placed in a 55-gallon drum for storage pending bulk disposal by SES Environmental. Figure 3 depicts the estimated free product/LNAPL isoconcentration contours. Groundwater Monitoring Monitoring wells MW-1, MW-2, MW-3, MW-4, MW-5, MW-6, and MW-7 were gauged as part of the monitoring event on June 17, 2024. Based on groundwater elevation data, groundwater flow appears to be directed to the southwest toward Moore Branch. This is consistent with historical observations. Monitoring well construction details are summarized on Table 1. Groundwater elevation data is summarized in Table 2 and a groundwater elevation map indicating groundwater flow direction is included as Figure 4. Field notes are included as Appendix A. Monitoring wells MW-2, MW-3, MW-4, MW-6, and MW-7 were sampled as part of the monitoring event on June 17, 2024. Monitoring wells MW-1 and MW-5 contained approximately 0.35 feet and 0.03 feet of free product, respectively. Groundwater samples were submitted to Pace Analytical in Asheville, NC for analysis of volatile organic compounds (VOCs) by EPA Method 6200 and semi-volatile organic compounds (SVOCs) by EPA Method 625. Laboratory analytical results indicate the following VOCs in excess of the NCAC 2L Standards: • Benzene: MW-3 (7,920 ug/l). • Toluene: MW-3 (16,900 ug/l). • Ethylbenzene: MW-3 (2,890 ug/l). • Total xylenes: MW-2 (981 ug/l) and MW-3 (14,330 ug/l). • Naphthalene (6200): MW-2 (95.2 ug/l) and MW-3 (538 ug/l). • N-Propylbenzene: MW-3 (279 ug/l). • Isopropylbenzene: MW-3 (103 ug/l). • 1,2,4-Trimethylbenzene: MW-2 (1,390 ug/l) and MW-3 (2,250 ug/l). • 1,3,5-Trimethylbenzene: MW-2 (444 ug/l) and MW-3 (509 ug/l). • 1,2,3-Trichloropropane: MW-2 (11.6 ug/l). Groundwater Monitoring Report Eblen Short Stop #2 Asheville, North Carolina 5 Additionally, benzene exceeded the GCL in MW-3. Laboratory analytical results indicate the following SVOCs in excess of the NCAC 2L Standards: • Naphthalene (625): MW-3 (555 ug/l). VOC groundwater quality data is included in Table 3. SVOC groundwater quality data is included as Table 4 and historical VPH/EPH groundwater quality data is included as Table 5. Groundwater quality data is included as Figure 5, a total BTEX isoconcentration contour map, is included as Figure 6 and a naphthalene isoconcentration contour map is included as Figure 7. The laboratory analytical report is included as Appendix B. Conclusions and Recommendations Based on the June 2024 monitoring event, laboratory results indicate that VOCs and SVOCs exceed the NCAC 2L Standards in MW-2 and MW-3. The analyte benzene exceeded the corresponding GCL in MW-3. Free product was detected in MW-1 and MW-5 at a thickness of 0.35 feet and 0.03 feet, respectively. The results of the June 2024 monitoring event are consistent with the historical data collected at the site. At this time, Singleton Environmental, Inc. recommends continuing pre-CAP monitoring activities with an MMPE for the next groundwater monitoring event to be conducted in December 2024. In addition, absorbent socks will continue to be replaced as necessary.

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.
