For additional information please refer to subsequent sections of this report. • As requested and approved in Pre -Approval Task Authorization (PATA) Number 18241- 20, a limited groundwater sampling event was performed. Groundwater quality samples were collected from seven (7) monitoring wells on February 20, 2017 by ATC LLC personnel. Samples were collected following the North Carolina Department of Environmental Quality (NCDEQ) "Guidelines for Sampling' dated July 15, 2008 with December 1, 2013 revisions. Utilizing a combination of a stainless -steel submersible pump and dedicated bailers, ATC LLC purged each monitoring well prior to sampling and placed groundwater samples in laboratory provided containers for laboratory analysis of volatile organic compounds (VOCs) by Environmental Protection Agency (EPA) Method 6200B and ethylene dibromide by EPA Method 504.1. During the February 2017 sampling event, the requested site monitoring wells were located and observed to be in good condition. In addition, no free phase product was encountered in the wells accessed during the reporting period; • A review of groundwater laboratory data revealed the samples collected from monitoring wells MW-3, TW-1, TW-2, TW-3, TWA and TW-5 contained levels of benzene in excess of the applicable GWQS. Samples collected from wells MW-1 R, MW-3, TW-1, TW-2, TW-3, and TW-4 contained levels of MTBE in excess of the applicable GWQS. Additionally, various other constituents were detected at concentrations above their respective GWQS in monitoring wells MW-1 R, MW-3, TW-1, TW-2, TW-3, TW-4, and TW-5 as summarized in Table 5. • Groundwater flow in the deep aquifer was interpreted to trend northwest. Groundwater flow in the shallow aquifer is unable to be determined without additional well gauging points. The average horizontal hydraulic gradient in February 2017 was calculated to be 0.025-feet per foot (ft/ft) and the average vertical hydraulic gradient was calculated to be 0.048-ft/ft in the downward direction; • In conclusion, based on the concentrations of petroleum hydrocarbons in the groundwater exceeding the GWQS for multiple constituents and the presence of a water supply well within 1,500-feet of the source area, the site will remain classified as a "High" risk. However, groundwater modeling should be considered as a path to incident closure.

The (former) Wilgrove Express facility is located at 10102 Albemarle Road within the city limits of Charlotte, Mecklenburg County, North Carolina (henceforth referred to as the "site"). A site vicinity map with topographic features is included as Figure 1. The activities were conducted in accordance with the Pre -Approval Task Authorization (PATA) as approved by the North Carolina Department of Environmental Quality (NCDEQ) dated February 6, 2017 (PATA No. 18241-20). The current PATA is included in Appendix A. The site is currently owned by Couchell Investment Company, LLC of Matthews, North Carolina and operates as leased commercial space. During the July 2016 sampling event, the site was developed with a one-story building and associated asphalt parking areas. Three (3) tenants were observed inside the site structure during the July 2016 site visit. Based on assessment information collected between 1997 and 2004, there was a release into the subsurface from one (1) 1,000—gallon kerosene underground storage tank (UST) that was subsequently removed and replaced upon the release confirmation in 1997. Based on information collected from assessment activities between 2006 and the present, the contaminant source of the second release was the former UST system, which was removed from the site on January 8, 2008. The former UST information is summarized on Table 1 and locations are illustrated on Figure 2. ;ETC 2.0 SITE HISTORY AND CHARACTERIZATION Page 2 The site operated as a gasoline station and convenience store for over 17-years. Release No. 1 was confirmed during removal of a 1,000-gallon kerosene UST on October 8, 1997. Two (2) soil samples were collected beneath the UST at closure, and laboratory analysis of one (1) of the two (2) soil samples reported a Total Petroleum Hydrocarbons -Gasoline Range Organics (TPH-GRO) concentration of 15-milligrams per kilogram (mg/kg). The NCDEQ standard for TPH-GRO in soil was 10-mg/kg as detailed in "Underground Storage Tank Closure Report" completed by CBM Environmental Services, Inc., (CBM) submitted on November 18, 1997. A Phase I Limited Site Assessment (LSA) was completed at the facility in April 1998. Additional soil sampling activities did not detect TPH-GRO or TPH-DRO (Diesel Range Organics) at concentrations above the method detection limits. Groundwater monitoring well MW-1 was installed adjacent to the former kerosene UST location during completion of the Phase I LSA. A groundwater sample collected from MW-1 on April 6, 1998 was laboratory -analyzed for BTEX (benzene, toluene, ethylbenzene, and total xylenes), MTBE (methyl tert-butyl ether), IPE (di - isopropyl ether), and naphthalene using EPA Methods 601/602, and benzene was detected at a concentration of 3-micrograms per liter (pg/L) at a level above the North Carolina Administrative Code 2L Groundwater Quality Standard (GWQS). No other compounds were detected above the method detection limits as detailed in a "Phase I Limited Site Assessment Report" completed by CBM dated May 15, 1998. Groundwater sampling efforts were completed at the site between 1998 and 2003. Additional groundwater samples were collected from well MW-1 from December 1998 to February 2003. Groundwater samples collected during this time period were analyzed for BTEX, MTBE, IPE, and naphthalene using EPA Methods 601/602. Laboratory analyses did not detect compound concentrations above the method detection limits from samples collected during these events. In November 2006, the on -site water supply well was sampled. The laboratory analysis indicated MTBE at a concentration of 1.5-pg/L. Based on this detected concentration, the NCDENR (North Carolina Department of Environment and Natural Resources') forwarded a "Notice of Regulatory Requirements" (NORR) to Mr. Irvin Perry, the UST owner/operator. The NORR required completion of a site check to include both tank and line tightness testing (in accordance with NC 15A NCAC 2N.0603). During July 16 and 17, 2007 a total of twenty-three (23) soil borings were completed with soil samples collected for laboratory analyses during performance of the site check. Based on the results of the site check it was determined that removal of the on -site UST system would be appropriate. The results of the site check activities were presented in the "Site Check Report" as prepared by Environmental Compliance Services, Inc. (ECS) dated July 31, 2007. On January 8, 2008, the former UST system was removed from the site. During the removal activities a total of 1,220-tons of impacted soil was excavated from two (2) areas: (1) the larger excavation area included the former gasoline and diesel UST locations and their dispensers; 1 NCDENR - predecessor to NCDEQ ;ETC Page 3 and (2) the smaller excavation encompassed the former kerosene UST and dispenser. Excavation activities were accompanied by confirmatory soil sampling. The total depths of the completed excavations ranged from approximately 12 to 17-feet below ground surface (BGS). The results of these activities were presented in the "UST Closure, 20 Day, and Initial Abatement Action Report" prepared by ECS dated March 3, 2008. Based on the results of confirmatory soil sampling performed after completion of the excavation activities, a LSA was initiated. During Phase I/Phase II LSA activities (May through July, 2008), concentrations of benzene and MTBE which exceeded the respective Maximum Soil Contaminant Concentrations (MSCCs) for soil -to -groundwater were detected in two (2) soil samples. Total xylenes were detected in excess of the soil -to -groundwater MSCC in one (1) soil sample. Benzene, ethylbenzene, naphthalene and MTBE concentrations were reported in excess of their respective 15A NCAC 02L .0202 Groundwater Quality Standards (GWQS) in two (2) of the five (5) on -site monitoring wells (MW-2 and MW-3). Total xylenes were reported in excess of the GWQS in monitoring well MW-3, and IPE was reported in excess of the GWQS in well MW-2. Wells MW-2 and MW-3 also contained concentrations of C5-C8 Aliphatics and C9- C18 Aliphatics in excess of the applicable GWQSs. Wells MW-1, MW-2 and MW-3 contained concentrations of C9-C22 Aromatics in excess of the GWQS. On October 1, 2008, the NCDENR issued a subsequent NORR requiring completion of a Comprehensive Site Assessment (CSA). During CSA activities, it was determined that the horizontal extent of contamination had been defined. The vertical extent of contamination was determined to have been adequately defined even though a single exceedance of 1,2- dichloroethane (1,2-DCA) was detected in monitoring well TW-3. Bedrock was encountered approximately 75-feet BGS. Results of the CSA were presented in the "Comprehensive Site Assessment Report" dated April 22, 2009, "Comprehensive Assessment Report — Addendum" dated September 30, 2009, and "Comprehensive Site Assessment Report — Addendum" dated January 20, 2010, all prepared by ECS. Due to the presence of contamination within the aquifer, a Corrective Action Plan (CAP) was developed by ECS detailing the design of a proposed air sparge (AS) and soil vapor extraction (SVE) system. The CAP was approved by NCDENR on September 22, 2010 and an air sparging and soil vapor extraction remediation system was installed in August 2011 which commenced active site remediation on April 19, 2012. Semi-annual groundwater sampling events coupled with bi-weekly remediation system operations and maintenance site visits were completed from the first quarter of 2012 to the fourth quarter of 2014. Results of these activities have been reported in "Active Remediation Monitoring Report" dated September 12, 2012 and March 27, 2014, both prepared by ECS. According to the "Active Remediation Monitoring Report" prepared by ECS and dated November 24, 2014, two (2) additional telescoping wells were installed per the NORR dated April 4, 2014. Following well installation, a dual -phase extraction (DPE) event was completed on monitoring well TW-1 which recovered approximately 155-gallons of petroleum impacted groundwater and 0.002-gallons of petroleum products as vapor. Subsequently, a groundwater ;ETC Page 4 sampling event was conducted to assess the effectiveness of the DPE event. It was determined that dual -phase extraction is not an effective method for reduction of petroleum hydrocarbons at the site. A NORR was received from the NCDEQ dated November 26, 2014. The NORR requested that the remediation system be winterized and shut -down. The decision to terminate remedial operations at the site was based on the monitored stability of the plume, availability of public water supplies in the area, and low efficiency of the remediation system. Additionally, groundwater sampling was requested to be performed annually as opposed to semi-annually. A groundwater sampling event was completed by ECS in February 2015. Groundwater quality data from samples collected in February 2015 revealed multiple constituents exceeding the applicable GWQS in site monitoring wells. Additionally, an updated receptor survey indicated that multiple receptors remain within 1,500-feet of the facility. An 8-hour AFVR event conducted in June 2016 recovered approximately 269-gallons of liquid and 0.02-gallons of vapor -phase petroleum hydrocarbon constituents from site monitoring wells TW-1 and TW-4. Subsequent groundwater quality data from samples collected in July 2016 revealed multiple constituents exceeding the applicable GWQS in onsite monitoring wells No additional information regarding other assessments or remediation efforts was obtained or reviewed prior to the completion of this report. 2.1 RECEPTORS/POTENTIAL RECEPTORS A receptor survey was completed by CBM during the Phase I LSA completed May 1998. A total of twenty-two (22) water supply wells were identified within a 1,500-foot radius of the site. Municipal water was available within a 1,500-foot radius of the site. An unnamed pond was identified within 1,500-feet of the site located on private property. No wellhead protection areas were identified within a 1,500-foot radius of the site. Subsurface utilities were not buried far enough below land surface to intersect the water table. A receptor survey update was completed by ECS in March of 2016. It was determined that a total of twenty-seven (27) active water supply wells were present within a 1,500- foot radius of the site. A site vicinity map indicating the locations of all water supply wells within a 1,500-foot radius of the site is included as Figure 3. Water supply well and other receptor information is presented in Table 3. 2.2 REGIONAL & LOCAL GEOLOGY According to the 1985 "Geologic Map of North Carolina", the site was located in the Charlotte Belt of the Piedmont Physiographic Province. The Charlotte Belt consists of Upper Precambrian and Cambrian amphibolite facies of metasedimentary and metavolcanic rocks intruded by granitic plutons ranging in age from 265 to 325-million years (Brown, 1985). ;ETC Page 5 The crystalline rocks of the Charlotte Belt were typically covered by a mantle of residual soil and saprolite ranging in depth from at least five to more than 60-feet. This residual soil layer provided an intergranular medium for recharge of precipitation to the underlying fractured crystalline bedrock. Surficial soils observed at the site consisted primarily of red to brown silty clay grading with increased depth into red to brown clayey silt. Previous assessment activities performed at the site determined the silty clay and clayey silt continued to a depth of at least 75-feet BGS. These soils were thought to be the result of in -place chemical weathering of the parent bedrock material. The previously determined depth to groundwater at the site ranged from approximately 14 to 24-feet BGS. 2.3 REMEDIAL PLAN STRATEGY A Corrective Action Plan was completed by ECS in September 2010 and subsequently approved by the NCDEQ. Air sparge and soil vapor extraction test wells were installed in May 2010 with pilot testing completed August 17 through August 19, 2010 consisting of a 12-hour aquifer test, an air sparge test, and a soil vapor extraction test. The tests were completed by Advanced Environmental Services, Inc. of Greensboro, NC. An AS/SVE system utilizing five (5) AS and four (4) SVE wells was installed in August 2011 and commenced operation on April 19, 2012. The system operated for approximately 2.75-years until it was shut down in December 2014. The decision to terminate remedial operations at the site was based on the monitored stability of the plume, availability of public water supplies in the area, and low efficiency of the remediation system. Details regarding remediation system operations and maintenance have been included in previous reports prepared by ECS. An 8-hour dual -phase extraction event was performed on June 27, 2014 on monitoring well TW-1 with observation of water table conditions at monitoring wells MW-3, TW-2, and TW-3. Free phase product was not detected in these wells. A total of 155-gallons of petroleum impacted groundwater was recovered from TW-1 during the DPE event. An 8-hour AFVR event conducted in June 2016 recovered approximately 269-gallons of liquid and 0.02-gallons of vapor -phase petroleum hydrocarbon constituents from site monitoring wells TW-1 and TW-4. Currently, the site is in a monitoring phase of corrective action. At this time, no additional remediation activities have been planned for the site. ;ETC 3.0 CURRENT ASSESSMENT INFORMATION Page 6 The current scope of work included a limited groundwater monitoring event in accordance with the PATA No. 18241-20 as approved by the NCDEQ dated February 6, 2017. 3.1 SITE HYDROGEOLOGY On February 20, 2017, ATC LLC mobilized to the site to perform a limited groundwater assessment event. The depths to groundwater and total well depths were measured in Type II monitoring wells MW-1 R and MW-3, and Type II I monitoring wells TW-1 through TW- 5. The groundwater elevation data is summarized on Table 4. Free product was not detected in the gauged monitoring wells during the February 2017 monitoring event. The depths to groundwater measured in the Type II monitoring wells MW1R and MW3 were measured to be 16.68-feet below top -of -Casing (TOC) and 16.72-feet below TOC, respectively. The groundwater elevations in the Type II monitoring wells MW1R and MW3, relative to a temporary benchmark with an assumed datum of 100.00-feet, were 92.63-feet and 93.76-feet, respectively. Groundwater flow in the shallow aquifer is unable to be reliably determined without additional well gauging points, therefore a shallow groundwater elevation map is not applicable and not provided in this report. The depths to groundwater measured in the Type III monitoring wells ranged from 17.90- feet below TOC (TW-2) to 19.86-feet below TOC (TW-3). The groundwater elevations in the Type III monitoring wells, relative to a temporary benchmark with an assumed datum of 100.00-feet, ranged from 74.54-feet (TW-3) to 76.76-feet (TW-5). A deep groundwater table elevation map for the Type III wells is included as Figure S. After review of the groundwater elevation data and application of the three point solution, groundwater flow in the deep aquifer was interpreted to trend to the northwest. Monitoring wells TW-1 and TW-3 screened intervals differ greatly from that of TW-2, TW-4, and TW-5, and were therefore not included in determination of the deep aquifer flow direction. The horizontal hydraulic gradient was determined by dividing the change in head between an upgradient monitoring well and a downgradient monitoring well by the horizontal ground surface distance between the wells. The horizontal hydraulic gradient in June 2017 was calculated to be 0.025-feet per foot (ft/ft) as measured between monitoring wells MW-3 and MW-1 R. The vertical hydraulic gradient was determined by dividing the change in head between a paired shallow and deep well by the mid -points of the screened intervals of a paired shallow and deep well. The vertical hydraulic gradient between monitoring well pair MW-3 and TW-1 was calculated to be 0.068-ft/ft in the downward direction. The vertical hydraulic gradient between monitoring well pair MW-3 and TW-2 was calculated to be 0.027-ft/ft in the downward direction. The average vertical hydraulic gradient was calculated to be 0.048 ft/ft in the downward direction. ;ETC 3.2 GROUNDWATER QUALITY Page 7 On February 20, 2017 utilizing a combination of submersible stainless steel pump with disposable polyethylene tubing, dedicated bailers with colorless nylon rope, and disposable powderless nitrile gloves, ATC LLC personnel purged and sampled seven (7) monitoring wells (MW-1 R, MW-3, TW-1, TW-2, TW-3, TW-4, and TW-5) and placed each groundwater sample in laboratory provided containers for laboratory analysis. Field parameters (i.e., dissolved oxygen, pH, temperature, oxidation reduction potential, and specific conductivity) were measured during the purging of the monitoring wells and are presented on the groundwater sampling logs included as Appendix B. Groundwater samples collected by ATC LLC during February 2017 were submitted to Pace Analytical Services (Pace) located in Huntersville, North Carolina, under chain -of -custody as documented in Appendix C. Groundwater analyses included benzene, toluene, ethylbenzene, xylenes (collectively referred to as BTEX), methyl-tert butyl ether (MTBE), naphthalene, 1,2-dichloroethane (1,2-DCA), di -isopropyl ether (IPE), 1,2,4- trimethyl benzene, 1,3,5-trimethyl benzene, isopropyl benzene (cumene), methylene chloride, n-propylbenzene, and n-butylbenzene by EPA Method 6200B and ethylene dibromide (EDB) by EPA Method 504.1. A review of groundwater laboratory data revealed the samples collected from monitoring wells MW-3, TW-1, TW-2, TW-3, TW-4, and TW-5 contained levels of benzene in excess of the applicable GWQS. Samples collected from wells MW-1R, MW-3, TW-1, TW-2, TW-3, and TW-4 contained levels of MTBE in excess of the applicable GWQS. Additionally, various other constituents were detected at concentrations above their respective GWQS in monitoring wells MW-1R, MW-3, TW-1, TW-2, TW-3, TW-4, and TW-5 as summarized in Table 5. Isoconcentration maps for all contaminants detected above the GWQS are illustrated on Figure 6 through Figure 15. A map with additional constituents which were detected and found to be below the applicable GWQS is included as Figure 16. A summary of current and historical groundwater analytical data can be found on Table 5. The laboratory report and chain of custody record are included as Appendix C. 3.3 GROUNDWATER QUALITY— HISTORICAL COMPARISON Based on a comparison of current groundwater quality data to previous data obtained from the July 2016 groundwater sampling event, the levels of MTBE have decreased at the locations of monitoring wells MW-1 R and MW-3 by 30% and 3%, respectively while increasing at the locations of monitoring wells TW-1, TW-2, and TW-3 by 14%, 11 %, and 54%, respectively. Current data from monitoring wells MW-1 R and MW-3 indicate dissolved concentrations of BTEX, naphthalene, 1,2-DCA, di -isopropyl ether (IPE), 1,2,4- trimethyl benzene, 1,3,5-trimethylbenzene, cumene, n-propylbenzene, n-butylbenzene, and lead at generally static or downward trending levels when compared to historical data. An increase in methylene chloride was observed in MW-1 R and MW-3 when compared to historical data, with the NCGWQS exceeded in both wells. ;ETC Page 8 Contaminant concentrations generally trended upward in Type III wells TW-1 and TW-2 located at the source area based on a comparison to data collected from the July 2016 groundwater sampling event. However, data collected at the locations of Type III wells TW- 4 and TW-5 indicated a decrease in overall VOC concentrations as compared to previous assessments. Concentrations of benzene, xylenes, MTBE, naphthalene, 1,2-DCA, EDB, IPE, 1,2,4-trimethylbenzene, and cumene above the their respective GWQS remain present within the intermediate to deep aquifer. Currently groundwater contamination exceeding the applicable GWQS at multiple locations and the presence of active water supply wells within 1,000-feet of the source area is responsible for the current risk setting of "High". ;ETC 4.0 CONCLUSIONS & RECOMMENDATIONS Page 9 Groundwater quality data from samples collected in February 2017 revealed multiple constituents exceeding the applicable GWQS in onsite monitoring wells as summarized in Table 5. Groundwater flow in the deep aquifer was interpreted to trend to the northwest. In conclusion, based on the concentrations of petroleum hydrocarbons in the groundwater exceeding the applicable GWQS for multiple constituents and the presence of active water supply wells within 1,500-feet of the source area, the site will remain classified as a "High" risk. At this time, we recommend implementation of a groundwater modeling scenario to evaluate the fate of remaining residual petroleum concentrations as a path to incident closure. ;ETC 5.0 LIMITATIONS Page 10 This report has been prepared for the exclusive use of Irvin Perry for specific application to the referenced site in Mecklenburg County, North Carolina.

All locations, dimensions, and property lines depicted on this plan are approximate. This plan should not be used for construction or land conveyance purposes. Horizontal, and vertical locations of wells, and selected site features determined through measurements made by representatives of ATC. Groundwater elevations are relative to a temporary benchmark with an assumed datum of 100.00 feet. Groundwater elevations are based on measurements made on 2/20/17.
