The property is bordered by Asheville Highway to the east, undeveloped and residential property to the west, commercial property to the north, and commercial and residential property to the south. The facility currently maintains six underground storage tanks (USTs) located near the southwestern portion of the property. On February 8, 2010, an automatic leak testing system at the Enmark 100 station identified an equipment malfunction on the unleaded product line. The unleaded product system was immediately shut down and a pressure test and helium test were conducted on the system to investigate the cause of the leak detection alarm. A UST-17A: UST Suspected Release 24-hour Notice Form was submitted to the NCDEQ. A contractor was retained to excavate in the area of the dispenser sump where the cause of the leak detection alarm was suspected on February 16, 2010. During excavation activities, groundwater was encountered in the excavation zone, and it was determined that free-product had impacted the water table. The NCDEQ was immediately contacted via telephone to discuss abatement measures, and a UST-61:24-hour Release and UST Leak Reporting Form was submitted to the NCDEQ. Since the discovery of a release in February 2010, multiple environmental assessments have been performed at the site. BLE submitted a proposal to conduct the comprehensive groundwater sampling event and NCDEQ granted Task Authorization pre-approval on May 19, 2022 (TA #28799-12). The groundwater sampling event was completed by BLE on August 17, 2022, and details of the sampling event are contained herein.

UST Incident #7262 was discovered in August 1987 and reported to be the result of overspill and line leaks. A Site Closure Report for UST incident #7262 was submitted to NCDEQ on August 30, 2002. UST Incident #28134 was reported on June 10, 2003. The release was reportedly the result of line leaks at a kerosene dispenser. NCDEQ issued a Notice of No Further Action for UST Incident #28134 on December 3, 2014. UST Incident #28217 occurred and was reported on October 4, 2004 when a backhoe severed a diesel line while excavating the footing for the new convenience store being constructed on-site. The impacted soil was excavated, and confirmation soil samples did not detect total petroleum hydrocarbons above laboratory method detection limits. UST Incident #28799 was identified in February 2010 when an automatic leak testing system at the Enmark 100 station identified an equipment malfunction on the unleaded product line. No non-UST releases or off-site chemical releases are known to impact the location of the UST release. Groundwater Sampling Event – August 2022 October 7, 2022 Enmark 100; NCDEQ ID #0-009202; Incident #28799 BLE Project No. J22-6919-17 5 of 7 3.4 Site Characteristics The subject site comprises approximately 0.89 acres of land and is bordered by Asheville Highway to the east, undeveloped and residential property to the west, commercial property to the north, and commercial and residential property to the south. The site has been graded relatively flat and appears to slope gently to the south. The site is covered primarily with asphalt and pavement, with grass and vegetation along the western portion of the property. Groundwater Sampling Event – August 2022 October 7, 2022 Enmark 100; NCDEQ ID #0-009202; Incident #28799 BLE Project No. J22-6919-17 6 of 7 4.0 GROUNDWATER SAMPLING On August 17, 2022, BLE personnel mobilized to the site to conduct a groundwater sampling event. BLE personnel accessed each of the fourteen groundwater monitoring wells currently associated with the site (MW-1, MW-2, MW-3, MW-5, MW-6, MW-7, MW-8, MW-9, MW-10, MW-11, MW-12, MW-13, MW-14, and DW-1) to measure the depth to groundwater and collect an analytical sample. Prior to sampling, each of the groundwater monitoring wells were developed by purging until field parameters stabilized. Monitoring well purging field logs are included in Appendix A. Sample containers were marked in the field with identifying numbers, properly preserved, placed into sample coolers, secured, and maintained at less than 4 degrees Celsius. The samples and chain-of-custody records were delivered to Pace Analytics in West Columbia, South Carolina for analysis of volatile organic compounds (VOCs) by Standard Method 6200B. 4.1 Groundwater Occurrence Site-wide stabilized groundwater level measurements obtained on August 17, 2022 ranged from 8.21 feet below top of casing (btoc) (MW-11) to 13.20 feet btoc (DW-1). 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. Groundwater flow is toward the south/southwest. 4.2 Groundwater Sampling Results Of the 14 groundwater monitoring wells sampled for laboratory analysis, the results from eight monitoring wells identified one or more compounds present in concentrations above their respective North Carolina Groundwater Quality Standards (NCGWQS). However, none of the detected contaminants were present in concentrations exceeding their North Carolina Gross Contamination Level. The results of the laboratory analyses are summarized in Table 2 and are shown on Figure 3. The historical laboratory analytical results are shown on Table 3. The complete laboratory data sheets are provided in Appendix B. Groundwater Sampling Event – August 2022 October 7, 2022 Enmark 100; NCDEQ ID #0-009202; Incident #28799 BLE Project No. J22-6919-17 7 of 7 5.0 CONCLUSIONS AND RECOMMENDATIONS BLE performed a comprehensive groundwater sampling event at the Enmark 100 facility located at 431 Asheville Highway in Brevard, North Carolina in accordance with NCDEQ Task Authorization Pre-Approval #28799-12. Our findings and recommendations are as follows: • All fourteen (14) monitoring wells associated with the site were sampled during the event. • No free-phase petroleum product was detected on site. • Laboratory analysis detected petroleum hydrocarbons above their respective NCGWQS in eight monitoring wells (MW-1, MW-2, MW-3, MW-5, MW-6, MW-8, MW-9, and DW-1). • No compounds were detected in concentrations exceeding their North Carolina Gross Contamination Level. • In general, the dissolved phase concentrations of petroleum contaminants in groundwater at the site continues to remain stable or decline. Based upon the results of this assessment, BLE recommends continued periodic groundwater sampling at the site to evaluate groundwater contaminant concentration trends.

All results listed in this report relate only to the samples that are contained within this report.Where sampling is conducted by the client,results relate to the accuracy of the information provided,and as the samples are received. Sample receipt,sample analysis,and data review have been performed in accordance with the most current approved The NELAC Institute (TNI)standards,the Pace Analytical Services,LLC ("Pace") Laboratory Quality Manual,standard operating procedures (SOPs),and Pace policies.Any exceptions to the TNI standards,the Laboratory Quality Manual,SOPs or policies are qualified on the results page or discussed below.

VOCs by GC/MS Hexachlorobutadiene was found in the method blank associated with batch 51984.However,since all samples are ND results are being reported and qualified with a "B"accordingly. The method blank for analytical batch 52366 contained Hexachlorobutadiene greater than the acceptance criteria.The associated samples did not contain detections for the target analyte;therefore, re-extraction and/or re-analysis of sample(s)was not performed.The data has been reported.
