The property is bordered by residential property to the south and east, and commercial properties to the north and west. Historically, five gasoline dispensers (dispensers 1/2, 3/4, 5/6, 7/8, and 9/10) and two auto-diesel dispensers (dispenser 11 and 12) were situated beneath a canopy located to the west of the convenience store and three diesel dispensers (dispenser 13/14, 13s, and 14s) and one kerosene dispenser (dispenser 15) were situated beneath a second, smaller canopy located to the south of the convenience store. The dispensers were connected to six underground storage tanks (USTs) (three 12,000-gallon, two 6,000-gallon, and one 3,000- gallon) located in a shared tank pit on the southeast corner of the subject property. From September 20, 2010 through October 8, 2010 the dispensers, USTs, and associated product piping were removed from the site in preparation for site demolition and rebuilding of the station. Existing groundwater monitoring wells associated with the site were properly abandoned prior to soil excavation and demolition activities. The UST closure activities and soil excavation were conducted in accordance with the North Carolina Department of Environmental Quality (NCDEQ) Underground Storage Tank Section Guidelines for Site Checks, Tank Closure, and Initial Response and Abatement for UST Releases dated December 1, 2008 (NCDEQ Guidelines) and details of the UST closure can be found in the Report of UST Closure and Soil Excavation by BLE dated January 3, 2011. Multiple environmental assessments have been performed at the site since that time. Pursuant to NCDEQ’s Task Authorization (TA #28107-18) a comprehensive groundwater sampling event was completed at the subject site. A summary of the groundwater sampling event is provided herein.

The following site information was obtained from a review of the NCDEQ UST database and conversations with knowledgeable persons. On March 24, 2003, a diesel product line at the subject site failed a simplicity line test, and also failed a precision line test conducted on the following day. On March 26, 2003, Precision Tank Services, Inc. performed a helium test and located a leak at the diesel tank. Petroleum impacted soil was excavated from the source area and the release was reported to the NCDEQ. 3.4 Site Characteristics The property comprises approximately 1.70 acres of land and is bordered by residential property to the south and east and commercial properties to the north and west. The subject site is relatively flat and almost entirely covered with asphalt and pavement except for perimeter planter areas to the north and east. Two newly constructed retention ponds are located on the southern portion of the property. The adjacent property to the south of the Site, across Royal Oaks Road, is identified as 2592 Hendersonville Road. The property is currently owned by Mr. Kevin Edins and there is an inactive water supply well associated with the property. According to Mr. Edins, he has no plans to re-activate the water supply well in the foreseeable future. BLE has discussed the possibility of abandoning the water supply well with Mr. Edins and he is considering that option. Annual Monitoring Report March 28, 2023 Enmark 815; NCDEQ ID #0-007365; Incident #28107 BLE Project No. J23-7154-17 5 of 6 4.0 GROUNDWATER SAMPLING Seventeen (17) groundwater monitoring wells (MW-16 through MW-19, MW-21, MW-22, MW-23, MW-25 through MW-31, MW-33, DW-1R and DW-2 were sampled for laboratory analysis on February 8 and 9, 2023. Monitoring well MW-20 and recovery well RW-01 were not sampled due to the presence of free-phase petroleum product. Sample containers were marked in the field with identifying numbers, properly preserved, placed into sample coolers, secured, and maintained at less than 4° Celsius. The samples and chain-of-custody records were delivered to Pace Analytical Services, Inc. in West Columbia, South Carolina for analysis of volatile organic compounds (VOCs) by Standard Method 6200B. As noted in the laboratory reports in Appendix C, the samples were received by the laboratory in good condition, in accordance with the laboratory’s quality specifications, and at a temperature of approximately 3.0° Celsius. As a quality control (QC) check, the laboratory analyzed random matrix spikes and matrix spike duplicates to detect possible matrix effects. 4.1 Groundwater Occurrence Site-wide stabilized groundwater level measurements obtained on February 8, 2023 ranged from 34.34 feet below top of casing (btoc) (MW-16) to 46.34 feet btoc (MW-29). A tabulation of the groundwater level data is provided on Table 1. A water table elevation contour map showing the occurrence and direction of groundwater flow is presented as Figure 2. 4.2 Groundwater Sampling Results Of the 17 groundwater monitoring wells sampled for laboratory analysis, groundwater from eleven (11) monitoring wells detected one or more compounds in concentrations above their respective North Carolina Groundwater Quality Standards (NCGWQS). One contaminant of concern, benzene, was identified in dissolved phase concentrations exceeding its North Carolina Gross Contamination Level (GCL) in two monitoring wells (MW-17 and MW-18). No other dissolved phase contaminants were identified in concentrations exceeding their respective GCL. The results of the laboratory analyses are summarized in Table 2. Isoconcentration maps for four prevalent contaminants of concern are provided as Figure 3 through Figure 6. The complete laboratory data sheets are provided in Appendix B. Annual Monitoring Report March 28, 2023 Enmark 815; NCDEQ ID #0-007365; Incident #28107 BLE Project No. J23-7154-17 6 of 6 5.0 CONCLUSIONS AND RECOMMENDATIONS Based on the current laboratory analytical data, the extent of the contaminant plume at the subject site appears to be substantially defined. However, free-phase petroleum product was detected in one monitoring well (MW-20) and one compound, benzene, was detected above the North Carolina established Gross Contamination Level in monitoring wells MW-17 and MW-18. Historically, AFVR events and passive free-phase petroleum recovery efforts have been effective at reducing free-phase petroleum product thickness at the site. Based on the presence of free-phase petroleum in monitoring well MW-20, BLE recommends AFVR events conducted monthly for a period of three months with ongoing passive recovery efforts between each event. Given the effectiveness of the passive recovery, BLE recommends increasing the frequency for emptying and replacing the recovery system to twice per month. Additionally, BLE recommends a comprehensive groundwater sampling event be performed at the site following the completion of the AFVR event to evaluate contaminant concentration trends.

The samples affected: YB10035-015. The matrix spike duplicate (MSD) was processed as the MS in the batch. The CCV and LCS associated with batch YQ68210 passed acceptance criteria, therefore the data has been reported.
