The Site is in the North Carolina Department of Environmental Quality (DEQ) Brownfields Program (ID: 23064-19-060). A Site location map is provided as Figure 1 and a Site map is provided as Figure 2. The Site is comprised of three parcels of land totaling approximately 12.12 acres in area (Parcel IDs: 16908401, 16908402, and 16908410) that are developed with a vacant 53,946-square foot (SF) automotive dealership building, a vacant 2,240 SF sales and office building, and a vacant 1,468 SF office building. The northwestern portion of the Site contains undeveloped wooded land and an unnamed tributary to Kings Branch. The remainder of the Site consists of asphalt-paved parking, access drives, and landscaped areas. The Site is planned to be redeveloped with four multi-family apartment buildings and associated amenities, two public streets, and surface parking. Historically, the eastern portion of the Site contained two residences and agricultural land, and the western portion of the Site contained undeveloped wooded land. The Site remained in this configuration until 1976, when the main dealership building was constructed and operated as Dick Keffer Pontiac Buick GMC. In 1981, the eastern Site building was developed and utilized for used car sales. In 1987, the western Site building was constructed and operated as a truck sales office and later a collision center office. In 2005, a building addition was constructed to the north portion of the main Site building and used for auto body and painting operations. The Site has operated 2 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx as an automotive dealership under several names since that time. The Site has been vacant since 2018. 3 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx 2.0 Background Information H&H conducted a Phase I ESA at the Site in April 2019 and identified the following Recognized Environmental Conditions (RECs): • The Site has been occupied by various automotive dealerships and used for service, repair, and paint/body shop operations from 1976 through 2018. Historically, the subject Site has been identified as a Resource Conservation and Recovery Act (RCRA)-Small Quantity Generator (SQG) of ignitable (D001) and spent non-halogenated solvent (F003 and F005) hazardous wastes. Several RCRA violations have been reported at the Site. The RCRA violations were cited for a lack of proper paperwork including a contingency plan, open drums of various wastes, unlabeled waste drums, and spilled waste observed on the sides and base of the drums. Regulatory compliance was met during subsequent inspections, and no further regulatory actions were taken. As the Site is currently vacant, hazardous waste management practices were not observed during the Site reconnaissance and no historical waste management documents were provided for review. Based on the length of time automotive operations were conducted at the Site (approximately 42 years), historical hazardous waste generation at the Site, the fact that several RCRA violations have been issued to the Site, and the lack of hazardous waste management documentation, H&H considered the potential for impact to the subject Site from historical automotive service, repair, and paint/body operations to be a REC. • H&H observed evidence of 23 subgrade hydraulic lifts located throughout the service garage. Of the 23 subgrade hydraulic lifts, 17 were single-piston lifts and 6 were double- piston lifts. The installation date of the subgrade lifts is unknown; however, it is likely the lifts were installed when the facility was constructed in the late 1970s. Lift inspection and/or maintenance records were not available for review. No apparent previous environmental assessment had been conducted associated with the subgrade lifts. Based on the length of time the lifts were likely in use, the lack of service and/or maintenance 4 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx records, and the lack of previous environmental assessment, H&H considered the potential for impact to the subject Site associated with the subgrade hydraulic lifts to be a REC. •H&H observed two oil/water separators (OWSs) located in the southwest and southeast portions of the Site. Fluids from floor drains located in the service garage and wash bay in the main Site building flowed into the OWS located in the southwestern portion of the Site prior to discharge to the municipal sewer system. Fluids from a floor drain located in a wash bay in the eastern Site building flowed into the OWS located in the southeastern portion of the Site prior to discharge to the municipal sewer system. The OWS installation dates are not known; however, it is likely the OWSs were installed when the buildings were constructed in the late 1970s and early 1980s, respectively. No service or maintenance records were available for review and no apparent previous environmental assessment had been conducted associated with the OWSs. Based on the likely age of the OWSs (approximately 42 years and 37 years), the lack of service and/or maintenance records, and the lack of previous environmental assessment, H&H considered the potential for impact to the subject Site from the OWSs to be a REC. •Properties in the immediate vicinity of the Site have been used for various commercial purposes since the late-1970s to the present. Based on file review activities, chlorinated solvents and petroleum-related compounds have been detected in groundwater at nearby properties located topographically upgradient of the subject Site at concentrations above the North Carolina Administrative Code (NCAC) 02L Groundwater Quality Standards (2L Standards) and/or DEQ Vapor Intrusion Groundwater Screening Levels (GWSLs). H&H considered the potential for impact to the subject Site (including the potential for vapor intrusion associated with future Site development) from nearby historical commercial use and the documented presence of groundwater impacts at nearby topographically upgradient properties to be a REC. Based on the results of the Phase I ESA, H&H conducted Phase II ESA activities at the Site in June 2019 that included the collection of groundwater, soil, soil vapor, and sub-slab vapor samples 5 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx for laboratory analysis. The assessment activities were conducted to assess the potential for impact to the subject Site from historical Site operations, upgradient contaminant sources, and to evaluate potential risks associated with future Site development, including the potential for vapor intrusion. A summary of the results of the Phase II ESA is provided below. Groundwater Summary • The results of analysis of the groundwater samples indicated that 1,2-dichloroethane (1,2- DCA) was detected at concentrations above the 2L Standard in one background/upgradient well (TW-6) and one well located west of the service garage and paint/body shop (TW-4, located generally downgradient of TW-6). No other compounds were detected in the groundwater samples at concentrations above 2L Standards and no compounds were detected in the groundwater samples at concentrations above the GWSLs. Soil Summary • Laboratory analytical results indicated that diesel range petroleum hydrocarbons (TPH- DRO) were detected at concentrations above the DEQ Action Level in nine (9) of the 23 former in-ground lift locations. The former subgrade lifts with identified impacts above the Action Level include Lift #1, #4A, #10, #11, #15, #17, #18A, #20, and #21. The in- ground hydraulic lifts and associated components were removed from the Site in July 2019 by the current property owner. However, petroleum-impacted soils identified at the above lift locations remain in-place at the Site. • The results of soil analysis indicated that no compounds were detected in soil at concentrations above the Residential or Commercial/Industrial PSRGs and background for metals. • Background soil sample analytical results indicated that low levels of arsenic and hexavalent chromium are present in soil at the Site at concentrations above PSRGs. The portion of the Site where background samples were collected has historically been undeveloped wooded land since before 1938. 6 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx Soil Vapor Summary • Laboratory analytical results indicated that tetrachloroethylene (PCE) was detected in sub- slab vapor sample SSV-4 and its duplicate (southern portion of service garage) at concentrations above the Residential Sub-slab and Soil Gas Screening Level (SGSL) but below the Non-Residential SGSL. Additionally, naphthalene was detected in sub-slab sample SSV-2, located in the southern portion of the paint/body shop, at a concentration slightly above the Residential SGSL but below the Non-Residential SGSL. • To further evaluate the detected compounds, H&H input the concentrations of the compounds detected in each sub-slab/soil vapor sample into the DEQ Risk Calculator. The results of the cumulative risk calculations indicated that potential carcinogenic and non- carcinogenic risks associated with the sub-slab/soil vapor detections are within the range of acceptable limits under both future residential and non-residential use scenarios. The Site received eligibility into the DEQ Brownfields Program on February 10, 2020. On February 24, 2020, a kick-off meeting was held at the Site with the DEQ Brownfields project manager Ms. Jordan Thompson, to discuss historical uses at the Site, previous assessment activities, and data gaps associated with current conditions at the Site in preparation for the multi- family development. This report describes Brownfields assessment activities conducted at the Site to address the remaining data gaps identified during the February 24, 2020 kick-off meeting. This assessment was performed in accordance with the DEQ-approved Brownfields Assessment Work Plan dated March 3, 2020 and included the collection of soil, groundwater, soil and sub-slab vapor, sediment, and surface water samples for laboratory analysis, and the completion of a receptor survey. . 7 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx 3.0 Brownfields Assessment Activities The Brownfields assessment activities were performed in general accordance with DEQ’s Inactive Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup (Guidelines) dated January 2020, the DEQ DWM Vapor Intrusion Guidance dated March 2018, and most recent version of the U.S. Environmental Protection Agency (EPA) Region IV Science and Ecosystem Support (SESD) Field Branches Quality System and Technical Procedures guidance. H&H conducted the Brownfields assessment activities on March 17 and 18, 2020. A discussion of the methods, analytical results, and conclusions of the Brownfields assessment activities are provided in the following sections. The sample locations (with Site plan overlay) are provided on Figure 3 and the in-ground lift sample locations are provided on Figure 4. 3.1 Soil Assessment Northwestern Portion of the Site (Historically Undeveloped) To further evaluate soil conditions in the historically undeveloped portion of the Site, H&H contracted with Mid South Environmental, Inc. (Mid South), a North Carolina-licensed driller, to advance one soil boring (SB-11) in the northwestern undeveloped portion of the Site via direct push technology (DPT) drilling methods. The soil boring was advanced to approximately 10 feet below ground surface (ft bgs). Continuous soil samples were collected, and field screened for indication of potential impacts by observation for staining, and the presence of organic vapors using a calibrated photoionization detector (PID). Evidence of obvious impact was not observed in soil boring SB-11. Therefore, H&H collected one sample from the two-foot depth interval with the highest PID reading (4-6 ft bgs; 12.5 parts per million by volume [ppmv]) for laboratory analysis. Following collection, the soil sample was placed in dedicated laboratory-supplied sample containers, labeled with the sample identification, date, and requested analysis, and placed in a 8 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx laboratory supplied cooler with ice. The samples were submitted to Pace Analytical Services, LLC (Pace), a North Carolina certified laboratory for analysis of VOCs by EPA Method 8260, SVOCs by EPA Method 8270, and RCRA metals plus hexavalent chromium by EPA Methods 6020/7471/7199. The VOC sample was collected as a grab sample from within the selected two- foot interval, and the remainder of the selected interval was field composited for collection of the SVOCs and metals samples. The RCRA metals include arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver. Former In-Ground Hydraulic Lifts To further evaluate soil impacts identified during the June 2019 Phase II ESA associated with the former in-ground hydraulic lifts, one soil boring was advanced via DPT drilling methods at the five previous sample locations with the highest TPH-DRO detections. The five former in-ground lift locations with the highest TPH-DRO concentrations include L-1, L-4A, L-11, L-15, and L-17. Continuous soil samples were collected, and field screened for indication of potential impacts by observation for staining, and the presence of organic vapors using a calibrated PID. Based upon the field screening results, H&H collected one sample from each boring for laboratory analysis. Following collection, the soil samples were placed in dedicated laboratory-supplied sample containers, labeled with the sample identification, date, and requested analysis, and placed in a laboratory supplied cooler with ice. The samples were submitted to Pace for laboratory analysis of VOCs by EPA Method 8260, SVOCs by EPA Method 8270, RCRA metals plus hexavalent chromium by EPA Methods 6020/7471/7199, and total PCBs by EPA Method 8082. H&H also collected samples from the soil borings for PCB congeners by EPA Methods 6009, and requested that the laboratory hold the samples pending analytical results for samples analyzed for PCBs by EPA Method 8082. 3.2 Groundwater Assessment To further evaluate groundwater conditions at the Site, soil boring SB-11 was advanced into the surficial aquifer via DPT drilling methods and the boring was converted to a temporary 9 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx groundwater monitoring well (TW-8). Groundwater was encountered in the boring at approximately 16 ft bgs, therefore the temporary well was set at approximately 22 ft bgs. The temporary monitoring well was constructed using 1-inch diameter PVC riser with a 10-ft section of PVC screen. A filter sand pack was installed from the bottom of the well boring to approximately 2 ft above the well screen, and a bentonite seal was installed above the filter sand pack. Prior to sampling, H&H developed the temporary monitoring well by removing at least three well volumes using a peristaltic pump. Once three well volumes were removed, the well continued to be purged using low-flow methods until field parameters of temperature, pH, specific conductivity, and oxidation reduction potential (ORP) stabilized and turbidity was less than 10 nephelometric turbidity units (NTU). Following stabilization of field parameters, the SVOC and metals samples were collected using low-flow sampling techniques. To reduce the potential for VOC-loss through the pump head, the VOC sample was collected utilizing the “soda straw” sampling method. The groundwater sample was collected directly into dedicated laboratory-supplied sample containers, labeled with the sample identification, date, and requested analysis, and placed in a laboratory supplied cooler with ice. The groundwater sample was submitted to Pace for laboratory analysis of VOCs by EPA Method 8260, SVOCs by EPA Method 8270, and RCRA metals by EPA Methods 6020/7470. The soil boring/temporary monitoring well location was estimated (horizontal and vertical elevations) using a sub-meter GPS unit. 3.3 Soil Vapor Assessment To further evaluate the potential for vapor intrusion associated with future Site buildings, H&H installed and sampled six temporary soil vapor sample points (SG-5 through SG-9 and Methane- 1) and three sub-slab vapor sample points (SSV-6 through SSV-8) within the future building footprints. 10 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx The soil vapor sample points (SG-5 through SG-8) were installed utilizing DPT methods to depths between five and ten ft bgs. A 6-inch stainless-steel screen point fitted with ¼-inch diameter Teflon® tubing was then advanced within the borehole to the maximum depth of each boring. Filter sand was placed around the annular space of the sample points and extended to approximately one- ft above the bottom of the borehole. The sampling points were completed by placing hydrated bentonite from the top of the filter sand to the ground surface. Using a syringe, each sample point was purged of a minimum of three times the volume of the annular space plus the tubing volume. Because the soil vapor points were installed utilizing DPT methods, each point was allowed to stabilize for a minimum of two hours after installation prior to sampling. To evaluate the potential for vapor intrusion associated with the existing building slab in the central portion of the Site, H&H installed and sampled three sub-slab vapor monitoring points at the Site (SSV-6 through SSV-8). The sub-slab vapor points were installed at locations more than ten ft from exterior walls. The sub-slab vapor points were installed by utilizing a hammer drill and 1½- inch diameter drill bit to advance a pilot hole into the concrete slab to a depth of approximately 1¾ inches below the surface. A drill guide was then placed in the pilot hole, and a 5/8-inch diameter drill bit was utilized to advance the boring through the concrete slab. Following concrete borehole advancement, loose concrete cuttings were removed from the boring using a bottlebrush and high efficiency particulate air (HEPA) vacuum. A Cox-Colvin Vapor Pin (vapor pin) assembly (brass sampling point and silicone sleeve) was seated in the borehole using an installation/extraction tool and hammer. The vapor pins were installed as flush-mount sample points capable of being secured with a stainless-steel cover that screws onto the sampling point and is seated within the pilot hole annulus. Prior to sampling the soil and sub-slab vapor points, a leak check was conducted at each location by constructing a shroud over the entire sampling train and flooding the air within the shroud with helium gas. Using a syringe, a sample was collected from the vapor in the shroud into a Tedlar® bag and analyzed for helium concentrations using a helium gas detector. Vapor from the sampling points was purged and collected outside of the shroud into a separate Tedlar® bag and analyzed 11 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx using the helium gas detector to ensure that helium concentrations were less than 10% of the concentration measured within the shroud. Helium was not detected in any of the vapor sample points. VOCs Following a successful field leak check, the soil and sub-slab vapor samples were collected into one-liter Summa canisters for laboratory analysis by connecting the Teflon sample tubing to an airflow regulator using a brass nut and ferrule assembly to create an air tight seal. Shut-in leak tests were performed on each Summa canister and sampling train prior to sampling. The airflow regulator was calibrated by the laboratory to allow the Summa canisters to fill slowly at a rate not greater than 200 milliliters per minute. Prior to and after the samples were collected, vacuum in the canisters was measured using a laboratory-supplied vacuum gauge and recorded by sampling personnel. The laboratory was instructed to use reporting limits that are below applicable DEQ screening levels for the VOCs to the extent possible. The vacuum pressure in each Summa canister upon completion of the sampling event was between three and six inches of mercury and no samples were allowed to reach zero inches of mercury. Upon completion of sample collection, the air flow regulator was removed from the Summa canister and the samples were submitted to Con-Test Analytical Laboratory, Inc. (Con-Test), a nationally accredited laboratory, for analysis of VOCs by EPA Method TO-15. The starting and ending vacuum in each canister was recorded on the sample chain-of-custody, and upon receipt of the samples, the laboratory recorded the final received vacuum pressure for each Summa canister. Methane To evaluate the potential for methane migration along the unnamed tributary and as requested by DEQ, H&H installed one soil vapor sample point near the unnamed tributary (Methane-1) and screened each soil/sub-slab vapor sample point installed as part of this Brownfields assessment for methane. The soil gas sample point located near the unnamed tributary was installed utilizing hand auger methods to a depth of approximately 5 ft bgs and was completed to the surface as described above. 12 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx Following successful field leak checks, H&H connected the LandTec GEM5000 to the sample tubing at each sample location and recorded measurements of methane, hydrogen sulfide, oxygen, carbon dioxide, and carbon monoxide. At each field screening location, H&H also collected ambient air measurements. The soil vapor sample points were estimated (horizontal and vertical elevations) using a sub-meter GPS unit. Interior sub-slab sample point locations were recorded using cross-measurements from exterior walls. 3.4 Sediment and Surface Water Assessment To evaluate the potential for impact to sediment and surface water in the on-Site unnamed tributary, H&H collected two co-located sediment and surface water samples from the unnamed tributary. One sediment and one surface water sample (SW-1/SED-1) were collected from an upstream location (northeast portion of Site), and one sediment and one surface water sample was collected from a downstream location near the western Site boundary (SW-2/SED-2). Samples were collected from downstream to upstream to reduce the potential for cross contamination. The sediment samples were collected from the shallow zero to 0.5 ft bgs interval utilizing a decontaminated stainless-steel hand auger. The VOC sample was collected as a grab sample from within the shallow zero to 0.5 ft interval, and the remainder of the selected interval was field composited for collection of the SVOCs and metals samples. The surface water samples were collected directly into dedicated laboratory-supplied sample containers. Upon collection, the sediment and surface water sample containers were labeled with the sample identification, date, and requested analysis, and placed in a laboratory supplied cooler with ice. The sediment samples were submitted to Pace for laboratory analysis of VOCs by EPA Method 8260, SVOCs by EPA Method 8270, and RCRA metals plus hexavalent chromium by EPA Methods 6020/7471/7199. The surface water samples were submitted to Pace for laboratory 13 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx analysis of VOCs by EPA Method 8260, SVOCs by EPA Method 8270, and RCRA metals by EPA Methods 6020/7470. The sediment and surface water sample locations were estimated (horizontal and vertical elevations) using a sub-meter GPS unit. 3.5 Quality Assurance/Quality Control H&H utilized standard quality assurance/quality control (QA/QC) practices during the Brownfields assessment activities. Non-dedicated sampling equipment was decontaminated using Liquinox detergent prior to and between each sampling location. H&H and Mid South wore nitrile gloves while handling samples. The groundwater, soil vapor, and sub-slab vapor samples were collected using dedicated tubing. The soil vapor and sub-slab vapor monitoring points were installed utilizing dedicated stainless-steel screen points/vapor pins. For field and laboratory QA/QC purposes, H&H collected one duplicate sample per media. H&H collected one duplicate groundwater sample from TW-8, one duplicate soil sample from L-11 and SED-2, one duplicate vapor sample from SSV-8, and one duplicate surface water sample from SW-2. The duplicate samples were analyzed for the same compounds as the parent samples. The results of analysis of the duplicate samples indicate good analytical repeatability. A laboratory supplied trip blank was placed into the laboratory supplied cooler that was used for the groundwater samples and also accompanied field personnel during water sample collection activities. The trip blank was analyzed for VOCs by EPA Method 8260. No VOCs were detected in the trip blank. In addition, H&H requested a Level II QA/QC data package from the laboratory and the laboratory reported values to the laboratory-specified method detection limits using J-flags. 14 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx 3.6 Boring Abandonment and Investigation Derived Waste Upon completion of the soil, groundwater, and soil vapor sampling activities, H&H directed the drilling contractor to abandon the borings with bentonite and/or grout. The well materials were removed from the temporary monitoring well borehole prior to abandonment. As evidence of significant impact was not observed, investigative derived waste (IDW) generated during the Brownfields assessment activities was thin spread within the vicinity from which the samples were collected in accordance with DEQ guidance. 15 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx 4.0 Brownfields Assessment Results The results of analysis of the soil samples are summarized in Table 1, the results of analysis of the in-ground lift soil samples are summarized in Table 2, the results of analysis of the groundwater samples are summarized in Table 3, the results of analysis of the sub-slab vapor samples are summarized in Table 4, the results of analysis of the soil vapor samples are summarized in Table 5, the results of methane field screening results are summarized in Table 6, the results of analysis of the sediment samples are summarized in Table 7, and the results of analysis of the surface water samples are summarized in Table 8. Laboratory analytical results of the samples collected during the Phase II ESA activities are also included in the tables, where applicable. Laboratory analytical data reports and chain-of-custody records are included in Appendix B. The results of the samples collected as part of this Brownfields assessment are discussed below. 4.1 Soil Analytical Results The analytical results of the soil sample collected from boring SB-11 were compared to the DEQ IHSB Residential and Industrial/Commercial PSRGs dated December 2019. Metals concentrations were first compared to Site specific background levels before comparison to the PSRGs. 4.1.1 Northwestern Portion of the Site (Historically Undeveloped) VOCs Analytical results indicate that no VOCs were detected in soil sample SB-11 at concentrations exceeding Residential or Industrial/Commercial PSRGs. SVOCs Analytical results indicate that no SVOCs were detected in soil sample SB-11 at concentrations exceeding laboratory method detection limits. 16 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx Metals Analytical results indicate that metals concentrations in soil sample SB-11 are consistent with Site specific background at the Site. Furthermore, as the northwestern portion of the subject Site has been historically undeveloped land since at least 1938, H&H considers the SB-11 metals analytical results to be representative of background levels at the Site. Laboratory analytical results indicate that arsenic was detected in SB-11 at a concentration of 2.89 mg/kg, which is above the Residential PSRG (0.68 mg/kg), below the Industrial/Commercial PSRG (3 mg/kg), and within the range of Site specific background (2.45 mg/kg to 3.12 mg/kg). Analytical results indicate that hexavalent chromium was detected in SB-11 at an estimated concentration of 0.396 J mg/kg, which is slightly above the Residential PSRG of 0.31 mg/kg, below the Industrial/Commercial PSRG (6.5 mg/kg), and generally within the range of Site specific background (0.569 J mg/kg to 0.797 J mg/kg). 4.1.2 Former In-Ground Hydraulic Lifts VOCs Analytical results indicate that no VOCs were detected in the former in-ground hydraulic lift samples at concentrations exceeding Residential or Industrial/Commercial PSRGs. SVOCs Analytical results indicate that no SVOCs were detected in the former in-ground hydraulic lift samples at concentrations exceeding Residential or Industrial/Commercial PSRGs. Metals Analytical results indicate that no metals were detected in the former in-ground hydraulic lift samples at concentrations exceeding Site-specific background and PSRGs. 17 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx PCBs Laboratory analytical results indicate that PCBs were not detected above laboratory method detection limits in any of the five former in-ground hydraulic lift sample locations. Because PCBs were not detected via EPA Method 8082, congener-specific sample analysis was not considered warranted. 4.2 Groundwater Analytical Results The laboratory analytical results of the groundwater sample collected from temporary monitoring well TW-8 were compared to the 2L Standards and the DEQ Residential and Non-Residential GWSLs. VOCs Analytical results indicate that no VOCs were detected in the sample collected from temporary well TW-8 or its duplicate sample at concentrations exceeding laboratory method detection limits. SVOCs Analytical results indicate that no SVOCs were detected in the sample collected from temporary well TW-8 or its duplicate sample at concentrations exceeding laboratory method detection limits. Metals Analytical results indicate that no metals were detected in the sample collected from temporary well TW-8 or its duplicate sample at concentrations exceeding 2L Standards or GWSLs. 4.3 Soil Vapor Analytical Results Laboratory analytical results of the sub-slab vapor and soil gas samples were compared to the DEQ DWM Residential and Non-Residential SGSLs dated February 2018. These screening levels are very conservative and are based upon a lifetime incremental cancer risk (LICR) of 1 x 10-5 for potential carcinogenic effects and/or a Hazard Index (HI) of 0.2 for potential non-carcinogenic 18 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx effects. Vapor intrusion mitigation for occupied structures is not typically considered unless the LICR exceeds the acceptable risk range of 1 x 10-4 to 1 x 10-6 for potential carcinogenic effects and a HI of 1 for potential non-carcinogenic effects. Sub-Slab Vapor Analytical Results Laboratory analytical results of the sub-slab vapor samples indicate that no VOCs were detected above SGSLs. Soil Vapor Analytical Results Laboratory analytical results of the soil vapor samples indicate that benzene was detected in sample point SG-8 (north of service garage) at a concentration of 270 micrograms per cubic meter (µg/m3), which is above the Residential SGSL of 120 µg/m3, but below the Non-Residential SGSL of 1,600 µg/m3. Additionally, 1,3-butadiene was detected in soil vapor points SG-5 (northwest portion of the Site; 23 µg/m3) and SG-9 (southwest portion of Site; 16 µg/m3) at concentrations above the Residential SGSL of 14 µg/m3, but below the Non-Residential SGSL of 180 µg/m3. No other VOCs were detected at concentrations above SGSLs in the soil vapor samples. Methane Field Screening Results Methane gas was not detected in any of the soil or sub-slab vapor sample points. 19 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx 4.4 Vapor Intrusion Sample Risk Calculations To further evaluate the detected VOCs, H&H input the concentrations of the compounds detected in each soil and sub-slab vapor sample into the DEQ Risk Calculator (May 2019 Version). Calculations were completed for both residential and non-residential use scenarios of the soil gas to indoor air exposure pathway to calculate cumulative potential carcinogenic and non- carcinogenic risks for the sub-slab vapor and soil gas samples. Copies of the calculations are provided in Appendix C and a summary of the calculated LICRs and HIs for each sample is provided below: Sample ID Resident Risk Exceeded?

Metals concentrations were first compared to Site specific background levels before comparison to the PSRGs. VOCs Analytical results indicate that no VOCs were detected in the sediment samples at concentrations exceeding Residential or Industrial/Commercial PSRGs. SVOCs Analytical results indicate that no SVOCs were detected in the sediment samples at concentrations exceeding laboratory method detection limits. Metals Analytical results indicate that no metals were detected in the sediment samples at concentrations exceeding Site-specific background and PSRGs. 4.6 Surface Water Analytical Results The surface water laboratory analytical results were compared to the NCAC 15A 2B Water Quality Standards (2B Standards) for Class C surface waters under both an acute and chronic exposure scenario (dated June 2019). According to the NC DEQ Surface Water Classifications website, Kings Branch (located approximately 200 ft west of the Site) is classified as a Class C water. Note that as Site-specific hardness was not collected for the surface water samples, H&H utilized an assumed in-stream hardness value of 25 mg/L in the DEQ Hardness-Dependent Metals Calculator (dated June 2019). The hardness-dependent metals include cadmium, lead, and silver. Note that this surface water standard is based upon human health for the consumption of fish, which H&H considers highly unlikely based upon the urban nature of the surrounding area, the small size of the tributary, and the difficult on-Site accessibility. 21 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx VOCs Analytical results indicate that no VOCs were detected in the surface water samples or duplicate sample at concentrations exceeding laboratory method detection limits. SVOCs Analytical results indicate that no SVOCs were detected in the surface water samples or duplicate sample at concentrations exceeding laboratory method detection limits. Metals Analytical results indicate that cadmium was detected in the upstream sample (SW-1) at an estimated concentration of 0.347 J µg/L which exceeds the calculated chronic 2B Standard (using an assumed hardness value of 25 mg/L) of 0.15 µg/L but is below the calculated acute 2B Standard of 0.82 µg/L. Additionally, lead was detected in the upstream sample (SW-1) and downstream sample duplicate (DUP-W-2) at estimated concentrations of 1.39 J µg/L and 0.734 J µg/L, respectively; which are above the calculated chronic 2B Standard (using an assumed hardness value of 25 mg/L) of 0.54 µg/L but below the calculated acute 2B Standard of 14 µg/L. 22 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx 5.0 Receptor Survey On March 18, 2020, H&H performed a receptor survey in accordance with Brownfields Program guidance. During the receptor survey, H&H completed the following activities: • Determined land use and zoning for the Site and surrounding properties and identified schools/daycare centers, residences, and structures with basements within a 1,000-ft radius of the subject Site. • Identified public water supply wells and surface water intakes within a one-mile radius of the Site and private water supply and irrigation wells on-site and within a 1,500-ft radius. • Identified utilities within a 100-ft radius of the subject Site and septic systems within a 500-ft radius of the subject Site. • Determined the presence of surface water bodies, surface water intakes, and wetlands within a 1,500-ft radius of the subject Site. A summary of the information obtained during the survey is provided below. The Brownfields Receptor Survey Form is included in Appendix D. A Receptor Survey Map is provided as Figure 5. 5.1 Land Use and Zoning The Site is comprised of three parcels of land totaling approximately 12.12 acres. Surrounding properties are currently used for various commercial/industrial purposes including office, retail, general storage, warehousing, and a concrete-mixing plant. The majority of the subject Site is zoned transit-oriented development – commercial center (TOD- CC). The southeast portion of the subject Site is zoned general industrial (I-2). According to our 23 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx review of Mecklenburg County tax records, surrounding properties are zoned TOD-CC and I-2. Surrounding zoning is presented on Figure 5. No schools, daycares, or structures with basements were identified within 1,000 ft of the Site. Single family residences were identified approximately 900 ft east of the Site. 5.2 Water Supply Site No water supply wells, or surface water intakes were identified at the Site. Off-Site H&H conducted a water supply well survey for public water supply wells located within a one- mile radius of the Site and private water supply and irrigation wells within a 1,500-ft radius of the Site. The water supply well survey was conducted via an intensive vehicular and pedestrian survey and by reviewing the DEQ Source Water Assessment Program’s (SWAP) online geographic information system map. The results of the well survey indicated no private water supply wells or irrigation wells were identified within the 1,500 ft search radii. H&H contacted Charlotte Water which indicated that municipal water is available to the Site and the area within a 0.5-mile radius of the Site. In addition, H&H observed evidence of municipal water availability (i.e., water meters and fire hydrants) in the survey area. 5.3 Utilities The Site and surrounding area are supplied with the following utilities located within a 100-ft radius of the subject Site: 24 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx • municipal water – Charlotte Water • sanitary sewage – Charlotte Water • electricity - Duke Energy • natural gas – Piedmont Natural Gas Municipal water lines and sewer main lines were identified along Old Pineville Road and Tyvola Road. H&H did not observe evidence of a septic system associated with the subject Site or within a 500-ft radius of the subject Site. Electric lines are primarily overhead in the vicinity of the subject Site. Natural gas lines run underground along the Old Pineville Road and Tyvola Road utilities easement as evidenced by valves observed at the surface. Stormwater at the Site is generally expected to sheet flow towards municipal stormwater inlets located throughout the Site or towards the on-Site unnamed tributary of Kings Branch. 5.4 Surface Water H&H reviewed the National Wetlands Inventory (NWI) online database mapper and the US Geological Survey (USGS) topographic map to determine the presence of surface water bodies and wetlands within a 1,500-ft radius of the subject Site. H&H observed an unnamed tributary to Kings Branch located in the northern and western portions of the Site. The unnamed tributary flows onto the Site from an underground stormwater culvert that discharges in the far northeast portion of the Site. The on-Site portion of the unnamed tributary flows across the Site from the northeast to the southwest. According to the NWI database map, no mapped wetlands are located on the subject Site. The NWI database map indicates that the nearest mapped wetland is Kings Branch, which is depicted as being located approximately 200 ft west of the subject Site. According to the DEQ SWAP online database, no public surface water supply sources were identified within a one-mile radius of the Site. 25 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx 6.0 Summary and Conclusions H&H has completed Brownfields assessment activities at the former Dick Keffer Pontiac Buick GMC Brownfields property located at 1001 Tyvola Road and 450 Minuet Lane in Charlotte, Mecklenburg County, North Carolina. The Brownfields assessment activities were conducted to further evaluate potential risks at the Site associated with future Site redevelopment and to address the remaining data gaps identified during the February 24, 2020 kick-off meeting. The Brownfields assessment activities included the collection of soil, groundwater, soil and sub-slab vapor samples, sediment samples, and surface water samples for laboratory analysis and completion of a receptor survey. A summary of the results of the Brownfields assessment activities is provided below. Soil Summary • Analytical results from soil sample SB-11 collected from the northwestern (historically undeveloped) portion of the Site do not indicate impacts above PSRGs and background for metals. • Analytical results of the soil samples collected from the former in-ground hydraulic lift locations do not indicate impacts above PSRGs and background for metals. PCBs were not detected in any of the former in-ground lift samples. Groundwater Summary • Analytical results of the groundwater sample (and duplicate) collected from temporary well TW-8 do not indicate impacts above 2L Standards or GWSLs. Vapor Intrusion Summary • Laboratory analytical results indicate that no VOCs were detected in the sub-slab vapor samples at concentrations above Residential SGSLs. 26 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx • Laboratory analytical results indicate that benzene was detected in soil vapor point SG-8 (north of service garage) at a concentration above the Residential SGSL but below the Non- Residential SGSL. Additionally, 1,3-butadiene was detected in soil vapor points SG-5 (northwest portion of the Site) and SG-9 (southwest portion of Site) at concentrations above the Residential SGSL but below the Non-Residential SGSL. No other VOCs were detected at concentrations above SGSLs in the soil vapor samples. • To further evaluate the detected compounds, H&H input the concentrations of the compounds detected in each sub-slab/soil vapor sample into the DEQ Risk Calculator. The results of the cumulative risk calculations indicate the potential carcinogenic and non- carcinogenic risks associated with the sub-slab/soil vapor detections are within the range of acceptable limits under both future residential and non-residential use scenarios. • Methane gas was not detected in any of the soil or sub-slab vapor sample points. Sediment Summary • Laboratory analytical results do not indicate impacts to the on-Site unnamed tributary above PSRGs and background for metals. Surface Water Summary • Laboratory analytical results indicate that VOCs and SVOCs were not detected in the surface water samples at concentrations above laboratory method detection limits. • Analytical results indicate the metals concentrations detected in the downstream tributary sample were similar or lower than to those detected in the upstream tributary sample. Receptor Survey Summary • The results of the receptor survey indicate that municipal water is supplied to the Site and the surrounding area and that no private water supply wells or irrigation wells were identified within the 1,500 ft of the Site. No schools, daycares, or structures with 27 S:\AAA-Master Projects\Stonehenge Real Estate Group - SHR\SHR-004 Tyvola Road\Brownfields\Assessment\Report\BF Assessment Report - Dick Keffer_(#23064-19-060).docx basements were identified within 1,000 ft of the Site. Single family residences were identified approximately 900 ft east of the Site. H&H identified underground municipal water and sewer main lines, natural gas lines, and aboveground electric and cable lines located within a 100-ft radius of the Site. The nearest surface water feature is the on-Site unnamed tributary to Kings Branch (although not a NWI mapped wetland feature). Based upon the results of the Brownfields assessment activities, H&H concludes the following: •H&H recommends that the previously identified petroleum-impacted soils in the vicinity of the former in-ground hydraulic lifts be managed in accordance with a DEQ-approved Environmental Management Plan (EMP). •As the results of two consecutive vapor intrusion assessments conducted at the Site in June 2019 and March 2020 indicate that calculated carcinogenic and non-carcinogenic risks at the Site are within the range of DEQ-acceptable limits under both future residential and non-residential use scenarios, vapor mitigation controls do not appear warranted for the future Site buildings.
