Executive Summary No free product was observed on the on the property during the monitoring property. During the monitoring period, groundwater samples were collected from six of the eight monitoring wells and from three neighboring water supply wells. Monitoring well MW-4 has been covered with gravel and could not be located on the day of the sample event. A building has been constructed over the location of well MW-3. While the floor of the building appears to be the former asphalt parking lot, equipment stored in the building prevented CESI personnel from accessing the well. Groundwater samples from the remaining six wells were collected on January 21, 2021, and submitted to Pace Analytical, Inc. (Pace) for analysis by EPA Method SM6200 B. The analytical results of water samples from four monitoring wells were reported at concentrations that exceed the 15A NCAC 2L standard. None of the water sample results were reported at concentrations greater than the Gross Contamination Level (GCL). Analysis of groundwater samples collected from the three water supply wells were reported to be below the sample detection limit. Based on isoconcentration contour diagrams prepared for dissolved hydrocarbons reported in groundwater samples collected January 21, 2021, the horizontal and vertical extent of dissolved petroleum hydrocarbons appear similar to the distribution of dissolved petroleum hydrocarbons reported in groundwater samples collected May 8, 2020. The data suggests that the dissolved hydrocarbon plume is stable. Monitoring Report Six-O-One Stop Property January 31, 2021 Page No. 3 C. Table of Contents A.

Site History and Characterization Since submittal of the CSA on March 4, 2016, no changes have occurred regarding the ownership or operation of the Property. The owner and operator information is listed on the cover of this report and in Table B-2. All of the underground storage tanks at this Property were removed in December 2013, and no new USTs have been installed. Information regarding the former underground storage tanks (USTs) is provided on Table B-1. A Street Atlas showing the location of the Property is provided as Figure 1. The Property location is shown on a portion of a United States Geological Survey Topographical Quadrangle Map as Figure 2. The location of the former tanks is shown on a Property Layout as Figure 3. The tanks of this report were underground. No evidence of aboveground storage tanks were observed or reported. No spills have been reported for the facility other than the discovery January 17, 2014, of petroleum parameters in soil samples collected from beneath the gasoline USTs, diesel and kerosene USTs, and the gasoline dispenser piping. The analytical results of soil samples collected September 8, 2014, from beneath the dispensers were reported to the North Carolina Department of Environmental Quality (DEQ) in a letter dated January 16, 2015. The precise source and timing of contamination is not known. All of the USTs were observed for evidence of corrosion or damage. No significant corrosion or damage was observed. Further release was prevented by pump out of the USTs prior to their removal from the ground. Removal of source material (contaminated soil) was initiated immediately following removal of tanks. Field screening results indicated that the areas of greatest contamination were beneath the northern ends of the gasoline USTs, the southern end of the kerosene and diesel USTs and the elbow of the gasoline dispenser lines. No historical UST releases, non -UST releases, or off -site releases have been reported. Site Characteristics: The Property consists of one irregular -shaped parcel located at the northwest quadrant of the intersection of Highway 601 south and Cold Springs Road. The area of the parcel is approximately 2.67-acres and is improved with a gas station/convenience store/ automobile service facility. The Property location is shown on a Street Atlas as Figure 1. According to the Cabarrus County Tax Assessor's GIS website, the Property Parcel Number is 55486177360000. Site Vicinity Characteristics: The Property vicinity is primarily residential and commercial use along U.S. Highway 61, with residential and agricultural land use away from the U.S. Highway 601 corridor.

One inactive potable well was observed on the northern portion of the Property. Adjoining properties are provided potable water by wells and by municipal water from a main located along Highway 601. CESI updated water supply information for properties within 1,000 feet of the Property. In April 2020, survey questionnaires were sent certified mail to properties within 1,000 feet of the Property. For those properties that refused delivery, CESI conducted a search for wells by reviewing aerial photographs and by viewing from municipal streets. A summary of the mailings and field reconnaissance for water supply wells is provided in Table B-5. The information is shown on a map as Figure 4. Topography. CESI obtained a copy of the USGS 7.5-minute topographic map, Concord, North Carolina Quadrangle, dated 1991. A copy of a portion of the topographic map showing the Property location is provided on Figure 2. The elevation of the Property is approximately 630 feet above mean sea level (msl). Based upon the topographic contours observed on the USGS topographic contour map, the Property is located on a southwest to northeast trending ridge. The slope is generally downward toward the east although the extreme western portion of the Property slopes toward the northwest. Vegetation: The Property consists of the building footprint, asphalt pavement, two canopies, a propane AST, and grass turf. Surface Water: No surface water was observed on the Property. The nearest surface water indicated on the topographic map is an unnamed stream located approximately 1,000 feet northwest of the Property. Monitoring Report January 31, 2021 Six-O-One Stop Property Page No. 7 Wells: One inactive potable well was observed on the northern portion of the Property. The well head is blocked and groundwater cannot be accessed. Buildings: The Property is improved with one single -story commercial building. The building is occupied by a convenience store and two automobile service bays. No other USTs or ASTs (other than one propane AST) were observed onsite. In 2019, a metal storage building was erected along the southeast side of the main building. The metal building has no floor and is used to store automotive parts. The Property Layout is shown as Figure 3. Surface Cover: The majority of the Property surface is covered by the building, asphalt parking lot, and turf. Soil Type: According to the USDA web -based soil survey of Cabarrus County, the surficial Soil at the Property is composed of Urban Land Complex.

A CAP has not been prepared for the site. E. Presentation of Current Site Assessment Information On January 21, 2021, CESI personnel measured the depth to water using a washed interface probe capable of measuring phase separated liquids as thin as 0.01 feet. No free product was encountered during the reporting period. Groundwater samples were collected from three water supply wells on January 21, 2021. The addresses of the water supply wells are: 5600 Cold Springs Road (Property Number 1 on Figure 5); 5677 Cold Springs Road (Property Number 12 on Figure 5); and, 5726 Old Monroe Circle (Property Number 28 on Figure 5). The water samples were collected from a hose bib on top of the well or the nearest hose bib available at the residence. No samples were collected through a hose. The water was allowed to flow for five minutes prior to collection of a sample directly into the laboratory supplied sample containers. The water samples were analyzed for volatile organic compounds using EPA Method SM 6200B. Based on the analytical report, no parameters were reported above the sample detection limit. A copy of the laboratory report and chain of custody record is provided in Monitoring Report January 31, 2021 Six-O-One Stop Property Page No. 8 Appendix 2. A summary of water supply well analytical results is provided on Table B-8. CESI attempted to retrieve a water sample from the onsite water supply well (well 1) but was unable to lower a bailer because of interference from the downhole pump cable and discharge line. This well is disconnected from the electrical supply and has reportedly not been used for many years. The nearest water supply well is located at 5600 Cold Springs Road (Property Number 1 on Figure 5). The owner of the well, Mr. John Plyer, stated that he was adamantly opposed to being connected to the city water supply which is available along Highway 601. Mr. Plyer's well is approximately 310 feet north and cross -gradient of monitoring well MW-2. On January 21, 2021, CESI personnel attempted to collect groundwater samples from wells MW- 1 to MW-8. Monitoring well MW-4 could not be located as the owner has spread gravel over this portion of the parking lot. Monitoring well MW-3 could not be sampled because it was blocked by automotive repair parts stored in a building constructed in 2019. The accessible monitoring wells were purged of three casing volumes using a new polyethylene bailer. A water sample was then collected for laboratory analysis. The water samples were collected into laboratory supplied sample bottles and immediately placed on ice. The samples were transported to Pace using Chain -of -Custody protocol. CESI requested that Pace analyze the water samples for VOCs using EPA Method SM6200B. The results of the groundwater analyses are summarized on Table B-4. A copy of the laboratory report and chain -of -custody record is provided in Appendix 3. Analysis of groundwater samples from the monitoring wells revealed gasoline parameters greater than the North Carolina Administrative Code (NCAC) 15A 2L standard in wells MW-1 and MW-2. None of the tested parameters exceeded Gross Contaminant Levels GCLs. The analytical results for benzene and Naphthalene were posted on a Site Layout and contoured. The resulting isoconcentration contour diagrams for benzene and Naphthalene are provided as Figure 8 and Figure 9, respectively. Based on a comparison of prior isoconcentration contour diagrams and those prepared from the January 21, 2021, sampling event, the dissolved hydrocarbon plume appears to be stable. According to the Geologic Map of North Carolina 1985, the Property is located in the Piedmont Physiographic Province. The dominant rocks in this region are composed mainly of metamorphosed mudstone and argillite of the Cenozoic Era. The rocks are thin to thick bedded, with bedding planes and angular cleavage common and occur interbedded with metasandstone, metaconglomerate, and metavolcanic rock. This area is geologically characterized by a thin layer of red Saprolite over fractured bedrock. Saprolite is defined as soft, earthy, clay -rich, thoroughly decomposed rock formed in place by chemical weathering of igneous and metamorphic rocks. The term is applied to any unconsolidated residual material underlying the soil and grading to bedrock below. Bedrock was not observed at the surface in the vicinity of the Property. Drilling of monitoring wells encountered a blocky, well consolidated mudstone from approximately 12-feet below grade to the maximum depth penetrated of 50-feet below grade. Depth to groundwater: Depth to groundwater measurements at the site revealed depth to water approximately 18 feet below grade. No free product was encountered. A summary of the water level data is provided on Table B-9. The piezometric surface contour diagram from data recorded January Monitoring Report January 31, 2021 Six-O-One Stop Property Page No. 9 21, 2021, is provided as Figure 10. The piezometric surface contour diagram indicates that groundwater flow is toward the southwest. No free product has been observed onsite. Based on the groundwater analytical results of samples collected January 21, 2021, the areal extent of dissolved hydrocarbons appears to be defined. CESI does not recommend further assessment at this time. F. Free Product Removal No free product has been observed at the site. G. Soil and Groundwater Remediation No remediation has been implemented at this site during the reporting period. The September 9, 2020 Notice of Regulatory Requirements (NORR) letter from the DEQ has ordered additional excavation in the area of the borings MW-2 and SB-6. It is CESI's understanding that the DEQ requested this excavation to remove soil in the vicinity of boring B-6 that was indicated in Table B-3 of the June 2020 Monitoring Report to be at concentrations greater that the Industrial Use MSCC's. However, during update of the tables with the new data and the most recent MSCC and Groundwater Quality Standard (GWQS) published by the DEQ, CESI discovered several inaccuracies in the table summary. In particular, the soil quality data for boring B-6 was not converted to milligrams per kilogram from micrograms per kilogram, as reported by the laboratory. The result presented data in the table that was 1,000 times greater than the actual analytical result. CESI reviewed all of the data tables for accuracy and to update current MSCC's and GWQS's. Based on our review of the corrected and updated Table B-3, none of the sample analytical results for this project have exceeded the Industrial Use MSCC. Four soil samples have exceeded the Residential Use MSCC. In light of this new information, CESI has not conducted excavation in the area of SB-6 and MW-2. H. Conclusions and Recommendations None of the tested parameters were reported at concentrations exceeding GCLs. Interview with the nearest water well owner, Mr. John Plyer of 5600 Cold Springs Road on May 8, 2020, and interview with the second nearest water supply well owner located at 5651 Cold Springs Road on January 21, 2018, stated that they did not want to connect to municipal water. CESI recommends preparation of a full-scale CAP designed to reduce dissolved groundwater concentrations to below the 2L standard.

Concord, NC 28025 (via email) Dear Mr. Glover: NORTH CAROLINA Environmental Quality September 9, 2020 Re: Notice of Regulatory Requirements 15A NCAC 2L .0407(b) [High Risk] Risk -based Assessment and Corrective Action For Petroleum Underground Storage Tanks Six-O-One Stop 5661 South Highway 601, Concord Cabarrus County Incident Number: 40338 Risk Classification: High The UST Section, Division of Waste Management (DWM), Mooresville Regional Office (MRO) received the June 10, 2020 Monitoring Reports on June 11, 2020. The report recommending additional assessment prior to conducting additional remedial actions. was reviewed and approved on June 24, 2020. The electronic copy has been loaded to the DWM's electronic document storage system (Laserfiche). The report states: • On May 8, 2020, CESI personnel attempted to collect groundwater samples from wells MW-1 to MW-8. Monitoring well MW-4 could not be located as the owner has spread gravel over this portion of the parking lot. Monitoring well MW-3 could not be sampled because it was blocked by automotive repair parts stored in a building constructed in 2019. Groundwater samples were collected from six of the eight monitoring wells and from three neighboring water supply wells. • Analysis of groundwater samples from the monitoring wells revealed gasoline parameters greater than the North Carolina Administrative Code (NCAC) 15A 2L standard in wells MW-1, MW-2, MW-7, MW-8. None of the tested parameters exceeded Gross Contaminant Levels GCLs. North Carolina Department of Environmental Quality I Division of Waste Management Mooresville Regional Office 1 610 East Center Avenue, Suite 301 1 Mooresville, North Carolina 28115 704.663.1699 • Based on a comparison of prior benzene and MTBE isoconcentration contour diagrams and those prepared from the May 8, 2020, sampling event, the dissolved hydrocarbon plume appears to be stable. However, concentrations increased in several wells indicating that rebound from adsorbed hydrocarbons is occurring. • Based on the groundwater analytical results of samples collected May 8, 2020, the areal extent of dissolved hydrocarbons appears to be defined except to the south for benzene. • Depth to groundwater measurements at the site are approximately 18 feet below grade. • No free product has been observed at the site. • One inactive potable well was observed on the northern portion of the Property. The well head was blocked and groundwater could not be accessed. The Property is provided water from the City of Concord. • An interview with the well owner for 5600 Cold Springs Road on May 8, 2020, and an interview with the second nearest water supply well owner located at 5651 Cold Springs Road on January 21, 2018, stated that they did not want to connect to municipal water. • The nearest surface water indicated on the topographic map is an unnamed stream located approximately 1,000 feet northwest of the Property. • Soil contaminant concentrations above industrial/commercial Maximum Soil Contaminant Concentrations remain in the vicinity of MW-2/SB-6 Per this Notice of Regulatory Requirements: • The next sampling event shall be conducted near the end of November 2020. The Monitoring Monitoring Report for the November 2020 sampling event is due no later than December 31, 2020. • Soil excavation shall be conducted in the MW-2/SB-6 to remove contamination above industrial/commercial Maximum Soil Contaminant Concentrations. Please note that sampling and correction action must be conducted in accordance with the Guidelines for Assessment and Corrective Action for UST Releases. Failure to comply in the manner and time specified may result in the assessment of civil penalties and/or the use of the other enforcement mechanisms.
