Monitoring Report May 20, 2020 Ray's Gulf ATC Project # 199RAA2001 2.0 EXECUTIVE SUMMARY ATC Associates of North Carolina, P.C. (ATC) has completed a Monitoring Report (MR), which included a 96-hour Mobile Multi -Phase Extraction (MMPE) event and groundwater sampling at the former Ray's Gulf facility. The site is located at 1501 South Mint Street, in Charlotte, Mecklenburg County, North Carolina. The MR was performed based on the Notice of Regulatory Requirements (NORR), dated February 20, 2020, and the subsequent Pre -Approval Task Authorization (PATA-03) by the North Carolina Department of Environmental Quality (NCDEQ), Division of Waste Management (DWM), Underground Storage Tank (UST) Section. The site is located at the south corner of South Mint Street and Summit Avenue. As part of the site activities associated with this MR, ATC subcontracted Advanced Environmental Services (Advanced) to conduct a 96-hour MMPE event on well MW-1. Approximately ten days after the MMPE event, the site monitoring wells were gauged for depth to water, purged of three standing water columns, and sampled. The groundwater samples were submitted to Pace Analytical Services, LLC (Pace) laboratory in Huntersville, North Carolina, and analyzed for volatile organic compounds (VOCs) by Standard Method 6200B. The site conditions based on prior and recent activities are summarized below: • No water supply wells or surface water bodies have been identified within 1,500 feet of the site; • Light non -aqueous phase liquid (LNAPL) was not measured in the wells before or after the MMPE, nor at the time of sampling. However, during the post-MMPE sampling event a film of LNAPL was observed in the bailer while purging monitoring well MW-1; • Approximately 4,782 gallons of water and approximately 15.86 pounds (2.58 gallons) of VOCs in the vapor phase were removed from MW-1 during the MMPE event. Monitoring well DMW-1 was connected to the MMPE system for four hours on the second day of the MMPE event; • During the MMPE event, groundwater levels in wells MW-2 and MW-3 decreased by 0.6 feet and 5.05 feet, respectively, suggesting groundwater flow toward well MW-1 during the MMPE event. • After the MMPE event, the concentration of benzene exceeded the Gross Contamination Level (GCL) in monitoring well MW-1 and the concentration of methyl tert butyl ether (MTBE) exceeded the GCL in DMW-1; • Other contaminants were detected at concentrations exceeding their 2L Standards in all wells sampled; • The depth to groundwater ranged from approximately 11.5 to 12 feet below ground surface (ft-bgs) on April 14, 2020; and • Groundwater is estimated to flow to the northwest. The concentrations of benzene in MW-1 increased slightly from the prior sampling event, while MTBE in DMW-1 increased by approximately 1.7 times from the September 2019 sampling result, to a concentration slightly higher than that detected in May 30, 2019. The total concentrations of VOCs in wells MW-1, MW-2, MW-3, and MW-4 decreased by 28%, 45%, 59%, and 36%, respectively. However, based on the benzene in MW-1 and MTBE in DMW-1, the MMPE alone Monitoring Report May 20, 2020 Ray's Gulf ATC Project # 199RAA2001 was not effective in reducing concentrations. The LNAPL sheen observed in MW-1 suggests the presence of residual LNAPL in the subsurface in the area. Note that the depth to groundwater in well MW-1 has been above the top of the screened interval, by approximately 3.15 to 7.3 feet over the course of the historical monitoring events. The concentrations of MTBE detected in the deep monitoring well DMW-1 are higher than those detected in well MW-1 by approximately 14 to 28 times. Based on the results of the recent MMPE and sampling event, ATC recommends additional assessment prior to conducting additional remedial actions. 3.0 SITE DESCRIPTION 3.1 Site Characterization ATC, under contract with Ray's Amoco, Inc., the current property owner, provided environmental services at the former Ray's Gulf facility, located at 1501 South Mint Street, Charlotte, Mecklenburg County, North Carolina. Figure I depicts the site on a topographic map. Three buildings currently exist on the property identified by Parcel ID 11908314, including a former service station building constructed in 1953, a former service station garage constructed in 1955, and a warehouse constructed in 1957. Municipal water is available to the site and surrounding area by Charlotte Water. 3.2 Site Background According to the NCDEQ's registered UST database, three 3,000-gallon gasoline and one 3,000- gallon diesel USTs were installed on March 5, 1956. According to the April 1990 UST closure report, the USTs were removed on March 23, 1990; however, note that the UST database indicates a permanent closure date of January 24, 1990. The former USTs were located in the area of the current 6,000-gallon gasoline USTs (Figure 2). The UST database also indicates that the current gasoline USTs and current 6,000-gallon diesel UST were installed in January 1990. UST system information is included in Table B1. UST owner and operator information is included in Table B2. Following removal of the former 3,000-gallon USTs, two soil samples were collected from beneath each of the four USTs and analyzed for Total Petroleum Hydrocarbons Gasoline and Diesel Range Organics (TPH-GRO and TPH-DRO, respectively), and for benzene, ethylbenzene, toluene, and total xylenes. The greatest TPH-GRO and TPH-DRO results were 8,400 milligrams per kilogram (mg/kg) and 2,700 mg/kg, respectively, with both results associated with the Diesel UST #4. No soil samples were collected from beneath the four dispensers or associated piping. In July and August 2018, ATC completed a Phase I Limited Site Assessment (LSA), which included conducting a receptor survey, installing groundwater monitoring well MW-1, and collecting soil and groundwater samples for laboratory analysis. The LSA findings indicated water supply wells or surface water bodies were not identified within 1,500 feet of the source area. Soil samples collected during the installation of well MW-1 contained naphthalene above the Soil -to -Groundwater Maximum Soil Contaminant Concentration (MSCC). The groundwater sample collected from well MW-1 contained benzene at a concentration of 7,720 µg/L, exceeding the GCL of 5,000 µg/L. Other contaminants were detected at concentrations exceeding 2L Standards. 3 Monitoring Report May 20, 2020 Ray's Gulf ATC Project # 199RAA2001 In May 2019, ATC completed field activities for a Rapid Risk Assessment (RRA), which included the installation of monitoring wells MW-2, MW-3, MW-4, and DMW-1, conducting a rising -head aquifer slug test, and a comprehensive groundwater sampling event. Based on the slug testing results, the hydraulic conductivity is estimated to be 1.7 feet per day (ft/d) or 6.0x10-4 centimeters per second (cm/s) and the groundwater flow rate would be approximately 0.13 ft/d or 46 feet per year, to the northwest. The laboratory analytical results indicated benzene and MTBE were detected at concentrations exceeding GCLs in wells MW-1 and DMW-1, respectively, and other contaminants were detected at concentrations exceeding their 2L Standards in all wells sampled. ATC recommended conducting an aggressive fluid -vapor recovery (AFVR) event to remove contaminated groundwater and reduce the concentration of petroleum constituents in the groundwater. On August 12, 2019, an 8-hour AFVR event was conducted using MW-1 as the extraction well, with 363 gallons of water removed. The deep monitoring well DMW-1 was connected to the AFVR system for approximately 30 minutes to ensure a thorough development of the well. The post-AFVR sampling of the monitoring wells indicated a slight reduction in the benzene concentration in well MW-1 from 9,750 µg/L to 7,200 µg/L, and a significant reduction in the MTBE concentration in well DMW-1 from 29,400 µg/L to 17,900 µg/L (less than the GCL). Based on the reduction in concentrations, an MMPE event was recommended to evaluate further reduction using a longer total fluid extraction method. 3.3 Site and Regional Geology The Geologic Map of the Charlotte I' X 2° Quadrangle, North Carolina and South Carolina, by Richard Goldsmith, et. al. (1988) indicates that the property is located within the Charlotte Belt of the Piedmont Physiographic Province. Rocks of the Piedmont are crystalline igneous and metamorphic rocks that were formed during Appalachian mountain building events during the Paleozoic Era, several hundred million years ago. The rock type beneath the site is reported as granodiorite and related granitoids, gray, medium -grained, massive to weakly foliated igneous rock. The shallow subsurface in most areas of the Piedmont contains residual soil overburden, including structure -free residuum, saprolite, and partially weathered rock (PWR), that derive from in -place weathering of the crystalline bedrock. Occasional areas containing recent deposits of alluvium in the uppermost subsurface are found near streams and rivers. Saprolite and PWR typically contain some relict structures from the original rock material. Depth to rock ranges from ground surface at occasional outcrops to depths of up to 100 feet in areas of easily weathered rock. Soil encountered at the site during installation of monitoring wells MW-1 and DMW-1 consisted of primarily sandy and silty clays, and sandy silts to a depth of approximately 27 ft-bgs and rock to the termination depths of 34 ft-bgs and 52 ft-bgs, respectively. Soils encountered during the installation of wells MW-2 and MW-3 were observed to be primarily clayey silts to depths of 25 and 24.5 ft- bgs, respectively, where the borings were terminated. Soil encountered during the installation of well MW-4 consisted of primarily silt, to a depth of approximately 25 ft-bgs, where the boring was terminated. 4 Monitoring Report May 20, 2020 Ray's Gulf ATC Project # 199RAA2001 3.4 Site and Regional Hydrogeology The shallow aquifer occurrence varies in depth from ground surface at springs, creeks, and rivers to as deep as 50 feet or more beneath upland surfaces in some parts of the Piedmont. Groundwater in the alluvium or unconsolidated residual material, including saprolite and partially weathered rock (PWR) or regolith, usually behaves as an unconfined, or water table, aquifer and will yield water with head elevation equivalent to the first elevation where water was encountered. Permeability varies with lithology and is typically relatively low in residual soils, with higher permeability in saprolite or PWR due to relict rock texture and variable susceptibility to weathering exhibited by different minerals in the rock. Groundwater flow in residual soils or alluvium is usually in rough concurrence with local topographic conditions and is toward local drainage features. The bedrock fractures or other planar features generally constitute the bedrock aquifer, with the surrounding rock material being effectively impermeable. Along with fractures, contacts between rock bodies probably constitute zones of significant groundwater occurrence in the bedrock. The surrounding material and overlying residuum tend to make the bedrock aquifer a semi -confined aquifer. That is, the overlying water and soil weight normally results in pressure that causes water in a borehole which intersects a fracture or other feature to rise above the elevation of the fracture or feature. Such features may not occur on predicable trends, at the same elevations, or even be present or directly connected in separate boreholes. In areas adjacent to creeks the bedrock groundwater generally discharges to the residuum or alluvium and then into the surface water. In upland areas away from surface water drainages, the bedrock aquifer is generally recharged by downward infiltration of residuum aquifer water at locations where fractures intersect the bedrock surface. The depth to groundwater was measured to be approximately 15.85 feet below the top of well casing (TOC) in monitoring well MW-1 on July 18, 2018, following the monitoring well installation. During the drilling of the boring for the well, there was no apparent indication of groundwater until 30 to 34 ft-bgs, within the bedrock. Based on historical depth to groundwater measurements in well MW-1, the static groundwater level has ranged from approximately 3.15 to 7.30 feet above the top of the screen. The depth to groundwater in the shallow monitoring wells has ranged from approximately 11.4 to 16.6 feet below TOC. The groundwater elevations in the deeper well DMW-1 have ranged from 0.02 to 0.52 feet deeper than in the shallow well MW-1, indicating a slight downward component of groundwater flow, with vertical gradients of 0.0048 to 0.022 feet/foot. For sites in the Piedmont, groundwater flow can be approximated based on topography with the groundwater surface being a subdued reflection of the land surface. Groundwater flow is generally from areas of higher topographic elevation (upgradient) to areas of lower topographic elevation (downgradient). Based on groundwater elevations on April 14, 2020, groundwater flow is to the northwest, with a horizontal gradient of approximately 0.016 feet/foot. The vertical gradient between MW-1 and DMW-1 was 0.0048 feet per foot, indicating the horizontal gradient being approximately 3.1 times that of the vertical gradient. 5 Monitoring Report May 20, 2020 Ray's Gulf ATC Project # 199RAA2001 4.0 RECEPTOR SURVEY During the Phase I LSA, ATC mailed water supply well forms via certified mail to property owners identified within 500 feet of the source area by the Mecklenburg County GIS website, and conducted a visual site reconnaissance within a 1,500 foot radius of the site to identify the existence of water supply wells or other potential receptors in the area. Based on information obtained from the receptor survey, no water supply wells were identified during site reconnaissance or from the returned water supply well forms, as summarized in Table B5. In addition, no surface water bodies were identified within 1,500 feet of the site. Properties within 1,500 feet of the site are generally commercial and residential. Properties adjacent to the site consist of commercial properties to the northwest, north, northeast, and southwest. A parking lot area is located to the southeast. Adjoining property owners are documented in Table B6. 5.0 MOBILE MULTI -PHASE EXTRACTION EVENT Between March 30, 2020 and April 4, 2020, Advanced performed a 96-hour MMPE event, and ATC personnel provided onsite supervision during startup and shutdown. Monitoring well MW- 1 was used as the target extraction well for the 96-hour MMPE event. Deep well DMW-1 was also connected to the vacuum for approximately 4 hours to see if a reduction in MTBE could be achieved similar to that observed following the 8-hour AFVR event. The monitoring well network (MW-1 through MW-4, and DMW-1) was gauged for liquid levels with an electronic oil -water interface probe prior to starting the MMPE event. LNAPL was not detected in any of the wells gauged. During MMPE activities, a liquid ring vacuum pump unit is plumbed to the designated extraction points, and a drop pipe is extended into the well through an airtight seal at the TOC and into the water column. Throughout the MMPE process, a cone of depression forms around the designated recovery points by drawing down the groundwater surface levels, thus causing impacted water surrounding the recovery point to be extracted. Petroleum -impacted soil vapor within the cone of depression and the overlying vadose zone is removed as part of the MMPE extraction process. The effluent air stream was monitored by Advanced. Organic vapor concentrations ranged from 500 parts per million (ppm) to 3,200 ppm over the course of the event. The MMPE event removed approximately 4,782 gallons of groundwater and approximately 15.82 pounds (2.58 gallons) of hydrocarbons as vapor. Upon completion of the MMPE event, liquid levels were gauged in the monitoring well network immediately after the system was turned off. LNAPL was not detected in any of the wells gauged. The groundwater levels in wells MW-2 and MW-3 decreased by 0.6 feet and 5.05 feet, respectively, suggesting groundwater flow toward well MW-1 during the MMPE event. The decreased groundwater levels in wells MW-2 and MW-3 indicate the radius of influence from the MMPE event encompassed the area of contamination on site. 6 Monitoring Report May 20, 2020 Ray's Gulf ATC Project # 199RAA2001 Field notes from the MMPE supervision are presented in Appendix A. Information provided by Advanced, which includes monitoring data and waste disposal manifests is provided in Appendix B. 6.0 GROUNDWATER CHARACTERIZATION 6.1 Groundwater Levels On April 14, 2020 monitoring wells MW-1, MW-2, MW-3, MW-4, and DMW-1 were gauged for depth to groundwater and total well depth. A site map showing the well locations is presented as Figure 2. An interface probe was used to measure the depth to groundwater from the TOC, and no LNAPL was indicated in any of the wells. However, while purging well MW-1, an apparent sheen of LNAPL was observed in the bailer. The measured depth to groundwater in the shallow wells ranged from 11.60 feet from TOC in well MW-3, to 12.05 feet from TOC in well MW-4. Based on these measurements, and measured TOC elevations, the shallow groundwater is estimated to flow to the northwest with a horizontal hydraulic gradient of approximately 0.016 feet per foot. Table B7 summarizes monitoring well construction details, depth to water measurements, and groundwater elevation calculations. A groundwater contour map is presented as Figure 3. 6.2 Groundwater Quality On April 14, 2020, groundwater samples were collected from wells MW-1 through MW-4 and DMW-1. A three -volume well purge was implemented prior to groundwater sample collection to ensure the collection of a representative groundwater sample. The groundwater samples were collected in laboratory -supplied preserved containers; entered into chain -of -custody control; placed on ice; and shipped to Pace Analytical Services, LLC in Huntersville, North Carolina. The groundwater samples were analyzed for petroleum constituents including volatile organic compounds (VOCs) via EPA Method 6200B. The analytical report for groundwater is included in Appendix C. Groundwater analytical results are summarized in Table B4. The groundwater analytical results were compared to the 2L Standards and GCLs, as summarized below. • The groundwater sample collected from well MW-1 contained benzene at a concentration of 7,250 µg/L, exceeding the GCL of 5,000 µg/L. The concentration increased slightly since the September 19, 2019 concentration of 7,200 µg/L. • The groundwater sample from DMW-1 contained MTBE at a concentration of 30,600 µg/L, greater than the September 13, 2019 concentration of 17,900 µg/L, and slightly higher than the May 30, 2019 concentration of 29,400 µg/L. The concentrations of MTBE in the deep monitoring well DMW-1 are higher than those detected in well MW-1 by approximately 14 to 28 times. • Other contaminants were detected at concentrations exceeding their 2L Standards. The total concentrations of VOCs in wells MW-1, MW-2, MW-3, and MW-4 decreased by 28%, 45%, 59%, and 36%, respectively. Based on the benzene in MW-1 and MTBE in DMW-1, the MMPE alone was not effective in reducing concentrations. The LNAPL sheen observed in MW-1 suggest the presence of residual Monitoring Report May 20, 2020 Ray's Gulf ATC Project # 199RAA2001 LNAPL in the subsurface in the area. Note that the depth to groundwater in well MW-1 has been above the top of the screened interval, by approximately 3.15 to 7.3 feet over the course of the historical monitoring events. As part of ATC's quality assurance and quality control (QA and QC) measures, a data review of the laboratory reports was conducted. During the data review, it was found that the samples were received from the laboratory in acceptable condition and properly preserved. The samples were analyzed within correct holding times and reported within the lab report, and the chain -of -custody was properly completed by all parties. The laboratory QC report shows that an internal blank was analyzed for each method that was used for the original samples. The laboratory fortified blank (LFB) and laboratory control sample (LCS) data results were also provided for each analytical method. Refer to the laboratory reports in Appendix C for details regarding QA results for the laboratory samples and any noted exceptions. Overall, ATC concludes that the laboratory results are usable and any exceptions do not significantly impact the conclusions presented in this report. 7.0 CONCLUSIONS AND RECOMMENDATIONS On behalf of Ray's Amoco, Inc., ATC has completed a Monitoring Report for the Ray's Gulf site, UST Incident Number 8608, which included a 96-hour MMPE event and groundwater sampling at the former Ray's Gulf facility. The site conditions based on prior and recent activities are summarized below: • No water supply wells or surface water bodies have been identified within 1,500 feet of the site; • LNAPL was not measured in the wells before or after the MMPE, nor at the time of sampling. However, during the post MMPE sampling event a film of LNAPL was observed in the bailer while purging monitoring well MW-1; • Approximately 4,782 gallons of water and approximately 15.86 pounds (2.58 gallons) of VOCs in the vapor phase were removed from MW-1 during the MMPE event. Monitoring well DMW-1 was connected to the MMPE system for four hours on the second day of the MMPE event; • During the MMPE event, groundwater levels in wells MW-2 and MW-3 decreased by 0.6 feet and 5.05 feet, respectively, suggesting groundwater flow toward well MW-1 during the MMPE event. • The concentration of benzene exceeded the GCL in monitoring well MW-1 and the concentration of MTBE exceeded the GCL in DMW-1; • Other contaminants were detected at concentrations exceeding their 2L Standards in all wells sampled; • The depth to groundwater ranged from approximately 11.5 to 12 ft-bgs on April 14, 2020; and • Groundwater is estimated to flow to the northwest. Based on the results of the recent MMPE and sampling event, ATC recommends additional assessment prior to conducting additional remedial actions. 8 TABLES TABLE B1 UST SYSTEM AND RELEASE INFORMATION RAY'S GULF 1501 South Mint Street Charlotte, Mecklenburg County, North Carolina NCDEQ Incident #8608 UST ID Number Contents Capacity allons Date Tank Installed Status of UST Was Release Associated With UST System?

The MMPE system was active for 96.0 hours. During the event vacuum at the recovery pump ranged from 15.0 to 22.0 inches of mercury (hg) and stabilized at approximately 21.0 inches of mercury. Airflow rates ranged from 2,600 to 3,200 feet per minute and stabilized at approximately 2,700 feet per minute. System temperature ranged from 104 — 134 degrees F and humidity ranged from 64 to 99 percent. Field gauged volatile organic compounds (VOC's) emissions decreased from 3,200 to 1,400 parts per -million (PPM) throughout the event. Groundwater / Product Mix Recovered: During the event a total of 4,782 gallons of product/water mix were removed from the site and properly disposed at a certified North Carolina disposal facility. No free product was observed in tanker. Total fluids recovered, was measured based on stick readings conducted during and following the event. Based on 96.0 hours of operation and a total of 4,782 gallons recovered, the average groundwater recovery rate was calculated to be approximately 49.81 gallons per hour. Events Results: Based on mass -removal calculations 15.86 pounds or 2.58 gallons of VOC's were removed as vapor. Using Dwyer magnehelic gauges, vacuum influence (inches of water) was measured at monitoring points MW-2 and MW-3. No measurable vacuum influence was identified at any monitoring point. Maximum draw -down was identified in MW-2 and MW-3 at 0.60 and 5.05 feet respectively. Following the event, no free product was identified in any well.
