Underground Lift Removal and Initial Abatement Action Report Former Keffer Collision 4800 East Independence Boulevard, Charlotte, Mecklenburg County, North Carolina ECS Project No. 08-10205-C February 11, 2015 2.0 PREVIOUS INVESTIGATIONS The site is identified as the former Keffer Collision located at 4800 and 4930 East Independence Boulevard in Charlotte, Mecklenburg County, North Carolina (Figures 1 and 2). ECS previously conducted a Phase I Environmental Site Assessment (ESA) for the site (ECS Project No. 08-10205 dated August 29, 2014). ECS identified the following recognized environmental conditions (RECs) with respect to the subject site. • The presence of underground hydraulic lifts in the body shop. • The staining of the concrete in the vicinity of the used oil aboveground storage tank (AST) in the body shop. • The historical use as of the site as an auto repair facility/body shop since the 1960s. • The lack of on -site underground storage tank (UST) closure documentation. • ECS considered the closed incident associated with the auto facility north of the site to be a Controlled REC (CREC) due to the Notice of Residual Petroleum as part of the incident closure; however, the former paint thinner USTs and the lack of UST closure documentation associated with this facility was considered a REC of the site. • A former gasoline service station located across Highway 74 adjacent to the site to the east. • A closed UST incident was located at the former car wash on the southeastern portion of the site; however sampling data from UST closure was not available. Based on a potential real estate transaction and in an effort to determine if the site had been adversely impacted by the RECs identified during the Phase I ESA, ECS was contracted to conduct an assessment of the site. ECS conducted a Limited Soil and Groundwater Assessment at the site (ECS Project No. 08-10205-A, dated October 3, 2014) to address the above mentioned RECs. The sample locations for this assessment are shown on Figure 3. Based on the results of the soil and groundwater assessment, ECS concluded the following: • Based on laboratory analysis, a release has occurred from three hydraulic lift tanks Based on the results of the assessment, ECS recommended the following: • Removal of the underground lifts and remediation of impacted soil. Underground Litt Removal and Initial Abatement Action Report Former Keller Collision 4800 East Independence Boulevard, Charlotte, Mecklenburg County, North Carolina ECS Project No. 08-10205-C February 11, 2015 • Install and sample two wells in the area of GW-2. The additional assessment indicated that exceedances of NC2LGWCS in GW-2A appear related to residual petroleum contamination from the former closed UST incident in this location. The concentrations do not exceed the applicable DWM Non -Residential Vapor Intrusion Screening levels or GCLs. The MTBE concentration in sample GW-213 may have originated from the adjacent gasoline service station across Highway 74 to the east based on groundwater flow and historic groundwater data for this facility reviewed by ECS. ECS recommended that a copy of this report be submitted to the current property owner. Based on the laboratory results, ECS understands that a regulatory reporting condition exists. ECS recommended that the property owner consult with legal counsel regarding their obligation to report this to the NCDENR A copy of the Limited Soil and Groundwater Assessment Report and the report of additional groundwater assessment of the closed UST incident are included in Appendix A. Based on the findings of the assessment, ECS was contracted to screen soils during removal of the eight underground lifts and to collect confirmatory soil samples and prepare this report. 3.0 SITE CHARACTERISTICS: The subject site consists of an approximate 5.51 acre parcel of land that is currently developed with an automotive dealership (the former Keffer Collision Center) and is located at 4800 East Independence Boulevard in Charlotte, Mecklenburg County, North Carolina (Figures 1 and 2). The site is identified as Mecklenburg County Parcel Identification Number 16301305. According to the Mecklenburg County Online GIS Department, the site is currently owned by Wilson 301, LLC whom recently acquired the property from Richard W. Keffer Jr. and Constance O. Keffer. The subject site is improved with three buildings. The first building is an approximate 28,071 square foot structure that is utilized as offices and body shop and was constructed in 1968. The second building is an approximate 7,546 square foot building that is utilized as storage and the spray booth and was constructed in 1986. The third building is an approximate 9,632 square foot building that is currently vacant and was constructed in 1968. The site is located in an area that can generally be described as residential/commercial. As determined from the USGS topographical map, Charlotte East, North Carolina (dated 1967; revised 1988) and Mint Hill (dated 1993), North Carolina quadrangles, the subject site is situated approximately 740-750 feet above mean sea level with topography sloping to the southwest. East Independence Boulevard is located along a ridgeline that acts as a surface water drainage divide. No structures or water bodies are depicted on the site. Based on a review of the topographic map and observations of general area and site topography, surface run-off would be expected to flow to the southwest with areas to the northeast considered topographically upgradient. The subject site is located within the Charlotte Belt of the Piedmont Physiographic Province. The soils encountered in this area are the residual product of in -place chemical weathering of rock presently underlying the site and/or historic depositional events. In general, shallow unconfined groundwater movement within the overlying soils is controlled largely by topographic gradients. However, as the groundwater percolates downward, it becomes controlled by the subsurface geologic conditions. Thus, the direction of 4 Underground Lift Removal and Initial Abatement Action Report Former Keller Collision 4800 East Independence Boulevard, Charlotte, Mecklenburg County, North Carolina ECS Project No. 08-10205-C February 11, 2015 groundwater movement in the deeper aquifers may not be consistent with the reflecting topography. Surface waters primarily recharge shallow aquifers by infiltration along higher elevations. Once in the shallow aquifer, the groundwater typically discharges into streams or other surface water bodies at lower elevations. The depth of the shallow water table is transient and can vary with seasonal fluctuations in precipitation. Groundwater movement in the shallow aquifer is generally from higher to lower elevations. As such, shallow groundwater is expected to flow generally to the southwest. Based on the presumed groundwater flow direction, properties located to the northeast appear to be upgradient relative to the site. However, regional influences may have an impact on groundwater flow. The actual groundwater flow direction cannot be determined without site -specific information obtained through the installation of groundwater monitoring wells. 4.0 SOIL REMEDIATION ACTIVITIES ECS was on -site to observe and document the removal of the eight (2604 through 2611) underground lifts, screen soils with a photo -ionization detector (PID), and collect confirmatory soil samples for semi -volatile organic compounds (SVOCs) and extractable petroleum hydrocarbons (EPH) from beneath each lift after removal. The lifts were removed between December 2 through 8, 2014. A sample was not collected from beneath lift 2610 during lift removal, because there was no evidence of a release,'and a soil sample had been previously collected during the previous limited soil and groundwater assessment (Appendix 1). Elevated PID readings or petroleum odors were not detected around seven of the eight underground lifts. However, as a precaution, fill sands immediately surrounding the lifts were excavated for off -site disposal. Screening of soil adjacent to lift 2611 exhibited elevated PID readings ranging between 20 to over 200 parts per million (ppm) and petroleum odors. Based on these readings, additional soils were excavated from the vicinity of lift 2611 and confirmatory soil samples collected from the base and sidewalls of the excavation after PID readings indicated that the majority of the impacted soil had been excavated. The soils were direct loaded into trucks for off -site disposal. The approximate location of the excavation areas and samples are shown on Figure 4. Soil excavation activities were terminated based on encountering apparent clean soil based on visual and olfactory observations and readings from a photoionization detector (PID). The sampler, wearing a new pair of nitrile gloves, placed the samples in laboratory prepared containers. Each container was labeled and placed in a cooler containing ice to maintain the samples at approximately 4° Celsius. The samples were submitted to Prism Laboratories in Charlotte, North Carolina (North Carolina Certification # 402) for chemical analysis for semi - volatile organic compounds (SVOCs) using EPA Method 8270 and for extractible petroleum hydrocarbons (EPH) using the Massachusetts Department of Environmental Protection (MADEP) Method. Note that samples 2611-S1 through 2611-S4 are identified in the lab report as samples 2611-51 through 2611-54. Chain -of -Custody Records and the laboratory results are included in Appendix B. 5 ' Underground Lift Removal and Initial Abatement Action Report Former Keffer Collision 4800 East Independence Boulevard, Charlotte, Mecklenburg County, North Carolina ECS Project No. 08-10205-C February 11, 2015 Based on the field readings, impacted soils adjacent to the lifts appeared to have been excavated. As a precaution, a sample collected from the location indicating the highest field screening was analyzed on a 48-hour rush. The analysis did not detect petroleum hydrocarbons, confirming the field findings that impacted soils had been excavated. Based on these findings additional remediation did not appear warranted, so the excavations were backfilled as the facility was an active automotive maintenance garage. Upon receipt and review of the laboratory analytical data, one parameter, extractable petroleum hydrocarbon (EPH) fraction C11-C22 Aromatics, was detected over North Carolina Department of Environment and Natural Resource (NCDENR) Soil -to -Water Maximum Soil Contaminant Concentration (MSCC) in soil samples collected from the beneath lifts 2605 and 2607 after removal. The sample from lift 2607 also exceeded the Residential MSCC. Analytical results did not exceed the Commercial MSCC. Based on these results, after the property was acquired by the new owner, additional soil excavation was conducted in the vicinity of lifts 2605 and 2607 on January 13 and 14, 2015. Soil was excavated to the maximum extent feasible due to limitations presented by the ceiling height, and limitations presented by a load bearing wall and utilities associated with an underground ventilation system. Following removal of additional soil, on -site personnel collected confirmation soil samples from the base and sidewall of each excavation. The sampler, wearing a new pair of nitrile gloves, placed the samples in laboratory prepared containers. The samples were submitted to Prism for chemical analysis for SVOCs using EPA Method 8270 and for EPH using the MADEP Method. Analysis of the soil samples did not detect SVOCs or EPH above the residential, non-residential or soil -to -water MSCCs in four of the 10 post excavation soil samples. Aromatic hydrocarbons in the C11-C22 range, were detected at concentrations exceeding the soil to water MSCC in soil samples 2607-B, 2607S-2, 2607S-3, 2605-B, 2605S-2, and 2605S-4 at concentrations ranging from 50 mg/kg, in sidewall sample 2605S-2, to 890 mg/kg, in sidewall sample 2607S-3. The concentrations in samples 2607S-2 and 2607S-3 also exceed the residential MSCC. Concentrations do not exceed the commercial MSCC. The results are summarized in Table 1, and the excavation limits are shown on Figure 4. Based on building structures preventing further excavation, no additional excavation was performed. Note that samples 2607S-2 through 2607S-4 are identified in the lab report as samples 26075-2 through 26075-4 and that sample 2605S-3 is listed twice, with the second listing corresponding to sample 2605S-4. Chain -of - Custody Records and the laboratory results are included in Appendix B. 5.0 WASTE DISPOSAL Approximately 231 tons of petroleum impacted soil was removed from the site for off -site disposal. The soils were disposed by Zebra Environmental at Earthtec in Sanford, North Carolina. The Waste Disposal Manifests are included in Appendix C. E Underground Lift Removal and Initial Abatement Action Report Former Keffer Collision 4800 East Independence Boulevard, Charlotte, Mecklenburg County, North Carolina ECS Project No. 08-10205-C February 11, 2015 6.0 CONCLUSIONS AND RECOMMENDATIONS Based on the results of the investigation, ECS has the following conclusions: ECS observed the excavation of approximately 231 tons petroleum -impacted soils from the location of the former underground lifts. Groundwater was not encountered during soil excavation activities. While petroleum contaminated soil is still present near two the former underground lifts, it does not exceed the commercial risk levels. Based on the intended use of the site for commercial uses, soils being under a building with a concrete slab, the availability of public water to the site and surrounding area, the site being in an urban area, and no groundwater contamination detected over NC2LGWQS in a monitoring well (UST-1, to evaluate a historic UST during the previous Limited Soil and Groundwater Assessment) installed as close as possible downgradient of the lifts (UST-1 GW is shown on Figure 4 and analysis is summarized in Table 2), ECS recommends no additional assessment and filing a Notice of Residual Petroleum (NRP) as a viable option to close out the incident. Installation of a well or wells inside the building would be limited due to the ceiling height and structures, and activities in the garage area. ECS recommends that this report be submitted to the NCDENR for their consideration for closure pending filing of a NRP restricting use of the site to commercial purposes. 7.0 QUALIFICATIONS The activities and evaluative approaches used in this assessment are generally consistent with those normally employed in assessments and remediation projects of this type. ECS' evaluation of site conditions has been based on our understanding of the project information and the data obtained during our field activities.

PROJECT INFORMATION The site is identified as Keffer Dodge located at 4800 and 4930 East Independence Boulevard in Charlotte, Mecklenburg County, North Carolina, Figure 1 and 2. ECS previously conducted a Phase I Environmental Site Assessment (ESA) for the site (ECS Project No. 08-10205 dated August 29, 2014). This Phase I ESA is currently being updated to include an additional building which was added on subsequent to the completion of the Phase I ESA; however, this assessment includes limited assessment of this parcel based on the information available with regards to this portion of the site at the time the field work was conducted. ECS identified the following recognized environmental conditions (RECs) with respect to the subject site. • The presence of underground hydraulic lifts in the body shop. • The staining of the concrete in the vicinity of the used oil AST in the body shop. • ECS considers the historical use as of the site an auto repair facility/body shop since the 1960s to be a REC of the site. • ECS considers the lack of on -site UST closure documentation to be a REC of the site. • ECS considers the closed incident associated with the auto facility north of the site to be a CREC; however, the former paint thinner USTs and the lack of UST closure documentation associated with this facility is considered a REC of the site. Subsequent to the Phase I ESA prior to conducting the limited soil and groundwater assessment, the following potential RECs (to be determined as part of the revised Phase I ESA) were identified. • A former gasoline services station located across Highway 74 adjacent to the site to the east. ' A closed UST incident at the former car wash that was not included in the prior Phase I ESA. A file review is being conducted as part of the revised Phase I ESA. Based on a potential real estate transaction and in an effort to determine if the site has been adversely impacted by the RECs identified during the Phase I ESA, ECS was contracted to conduct an assessment of the site. Project information is based on correspondence between Ms. Ashley Dickerson with Sifen Incorporated and Mr. David Valentine and Mr. Brian Olin with ECS and the previously cited Phase I ESA. 2. SCOPE OF SERVICES The soil and groundwater assessment consisted of collecting a soil and groundwater samples using a Geoprobe® drill rig. The subcontractor used for this project was Carolina Soil Investigations, LLC (CSI). The soil borings and temporary wells were installed and abandoned on September 22, 2014. The Geoprobe® consists of a hydraulic jack mounted on all -terrain vehicle (ATV). The Geoprobe® is capable of driving various forms of groundwater, soil, and soil -gas sampling probes into the ground to depths equivalent of auger refusal. Keffer Dodge Charlotte, Mecklenburg County, North Carolina ECS Project No. 08-10205-A October 3, 2014 Prior to commencing with field activities, ECS contacted North Carolina One Call to locate/mark public utilities at the site. Required separation distances between subsurface activities and marked utilities (typically 30-inches) were maintained during the field activities. As part of this assessment, ECS prepared a site -specific health and safety plan (HASP) for the site. The HASP documented the known or suspected hazards, applicable personal protective equipment (PPE) of site personnel, and emergency response procedures. Prior to commencing with field activities, ECS and its subcontractors and applicable site personnel reviewed the site - specific HASP. Soil Sampling Six soil samples (WO-1, L-1 through L-4, and UST-1) were collected using a Geoprobe®. The borings were located to assess the RECs identified in ECS's Phase I ESA. Additionally one soil sample was collected from the saturated zone in boring GW-2 as no groundwater recovered into the temporary well or Geoprobe® groundwater sampling tool. The sample locations are shown on Figure 3. Soil samples were collected using a five-foot Macrocore sampler with a dedicated disposable polyethylene liner. Boring logs, which includes descriptions of the soils encountered and field screening results, were prepared for each boring and are included in the Appendix. Upon completion, the borings were properly abandoned and the floor /ground patched with concrete or asphalt. The soil samples collected in the field were transferred into a new, clean resealable bag (half full), and the bag placed in a warm location. Approximately ten minutes after the time of collection, the bag was opened slightly and the probe of a Photovac Microtip 2000 photoionization detector (PID) was inserted, and the bag immediately resealed using finger pressure. The meter of the PID was monitored and the reading recorded. Elevated PID readings were not detected in the borings. Groundwater Sampling ECS observed and documented the installation of three temporary monitoring wells (UST-1, GW-1, and GW-2) at the site (Figure 3). Temporary monitoring well UST-1 was located near the UST system at the site. Temporary monitoring well GW-2 was located topographically downgradient of an adjacent gasoline service station and in the location of a closed LUST incident at the former car wash. Despite saturated soil conditions being observed in boring GW-2 at 15 feet below ground surface (bgs) after two to three hours less than one inch of water was present in the temporary well and the water level did not appear to be increasing. Based on no water recovery at this location the Geoprobe® groundwater sampling tool was used to attempt to obtain a groundwater sample, but no water could be obtained using this method. Based on no recoverable water at this location a soil sample was collected from the saturated zone at this location to assess groundwater conditions as a slight petroleum odor was noted in the saturated zone soils at fifteen feet bgs. Temporary monitoring well GW-1 was located in a low lying area in the center of the site between UST-1 and GW-2. The sample locations are shown on Figure 3. Kefferpodge Charlotte, Mecklenburg County, North Carolina ECS Project No. 08-10205-A October 3, 2014 The temporary wells were drilled approximately five to ten feet into the groundwater table (encountered at approximately 15 to 20 feet bgs) to an approximate depth of 25 feet bgs. The temporary wells were constructed with one -inch I.D. Schedule 40 PVC flush -threaded casing and screen. The PVC screen and casing was lowered into the open borehole. A fifteen -foot length of slotted well screen with machined 0.010-inch slot widths and a threaded bottom plug were installed at the bottom of each well. The screens were installed to a depth such that the screened interval intersected the estimated groundwater surface. A solid section of PVC casing was placed above the screened interval and extended to a point just below the ground surface. The annular space around each well was filled with a washed and graded medium sand to approximately two feet above the top of the screen. A boring log was prepared for each temporary monitoring well, which is included in Appendix II. The temporary monitoring wells were sampled using a peristaltic pump and new, dedicated polyethylene tubing. Immediately after collection, the groundwater samples were transferred into sample containers provided by the laboratory. Upon completion, the temporary groundwater points were abandoned after the groundwater samples were collected. The soil and groundwater samples were placed into laboratory prepared containers. The sample containers were labeled with ECS project number, sample identification, sample date and time, and requested analytical analysis. The containers were placed into protective packaging material and placed into a cooler with ice to maintain the samples at approximately 4° Celsius (CO). The samples were submitted to (Prism Laboratories located in Charlotte, North Carolina (North Carolina Certification # 402) for chemical analysis. The soil and groundwater samples were analyzed for volatile organic compounds (VOCs) using EPA Method 8260, semi -volatile organic compounds (SVOCs) using EPA method 8270, and extractable and volatile petroleum hydrocarbons (EPHNPH) using the Massachusetts Department of Environmental protection (MADEP) methods. ECS maintained proper chain -of -custody (COC) procedures throughout the sample collection and transportation process. A copy of the COC is included in the Appendix. 3. RESULTS Laboratory analysis of soil samples WO-1, L-2, L-4 and UST-1 detected VOCs, SVOCs, EPHNPH and metals above laboratory detection limits; however, the concentrations do not exceed the applicable North Carolina Maximum Soil Contaminant Concentrations (MSCCs). Laboratory analysis of groundwater samples UST-1 GW and GW-1 detected VOCs, SVOCs, and EPHNPH above laboratory detection limits; however, the concentrations do not exceed the applicable North Carolina 2L Groundwater Quality Standards (NC2LGWQS) or Division of Waste Management (DWM) Non -Residential Vapor Intrusion Screening Levels. Laboratory analysis of soil samples L-1, L-3 and L-4 detected C-11-C22 Aromatics and Arsenic above laboratory quantitation/detection limits; with the concentrations in samples L-1, L-3 and L- 4 of C-11-C22 Aromatics ranging from 270 to 360 milligrams per kilogram (mg/Kg) exceed the Soil to Water MSCC of 31 mg/Kg and concentrations of arsenic in samples L-1 and L-3 ranging from 2.5 to 3.6 mg/Kg which exceed the North Carolina Department of Environment and Natural Resources (NCDENR) Inactive Hazardous Sites Branch (IHSB) Industrial Soil Remediation Goal of 2.4 mg/Kg. The remaining compounds detected do not exceed the applicable soil cleanup criteria. 19 Kefferpodge Charlotte, Mecklenburg County, North Carolina ECS Project No. 08-10205-A October 3, 2014 Laboratory analysis of sample GW-2 detected several VOCs, SVOCs, and EPH/VPH above laboratory detection limits; with the concentration of 1-methylnaphthalene exceeding the Soil to Water MSCC. This sample was collected in the saturated zone to assess groundwater as sufficient groundwater for sampling could not be recovered. The results of this sample are also listed on the groundwater table for comparison purposes; however, the results were not compared to NC2LGWQS since it was a soil analysis. This sample was located near the location of the former closed LUST incident. A summary of the laboratory analytical results is included in Tables 2 and 3. The laboratory data sheets are included in the Appendix. 4. CONCLUSIONS Based on the results of the soil and groundwater assessment, ECS concludes the following: • On September 22, 2014, ECS observed and documented the advancement of seven soil borings, one groundwater boring and the installation of three monitoring wells at the site. • Evidence of a release (petroleum/chemical odors, staining, sheens, elevated readings on the PID) was identified in boring GW-2 consisting of petroleum odors in the saturated zone of boring GW-2. Evidence of a release was not identified in the remaining borings during assessment activities. • Groundwater was encountered at an approximate depth of 15 to 20 feet bgs. • Drilling refusal was encountered at depths ranging from 15 to 24 feet bgs. • Six soil, two groundwater, and one soil sample from the saturated zone (GW-2) to asses groundwater were submitted to a certified laboratory for chemical analysis for VOCs, SVOCs, EPH/VPH, and/or metals. • Laboratory analysis of soil samples detected targeted analytes at concentrations that exceed the applicable North Carolina MSCC in samples L-1, L-3, L-4 and GW-2.. • Laboratory analysis of groundwater samples detected VOCs and SVOCs above laboratory reporting limits, but did not detect targeted analytes at concentrations that exceed the NC2LGWQS. Evidence of a groundwater impact was identified based on odors and soil smapling in the saturated zone in boring GW-2. This sample was located in the location of the closed former LUST incident. An off -site gasoline service station is also located on an adjacent property across Highway 74 topographically upgradient of this location. • The extent of impact to the site has not been fully delineated. Additional assessment would be necessary to fully delineate the extent of impact to the site. Keffer Dodge Charlotte, Mecklenburg County, North Carolina ECS Project No. 08-10205-A October 3, 2014 5.

Limited Site Assessment Report Former Keffer Collision 4800 East Independence Boulevard, Charlotte, Mecklenburg County, North Carolina ECS Project No. 08-10205-D August 21, 2015 2.0 SITE HISTORY The site is identified as the former Keffer Collision located at 4800 and 4930 East Independence Boulevard in Charlotte, Mecklenburg County, North Carolina (Figures 1 and 2). ECS previously conducted a Phase I Environmental Site Assessment (ESA) for the site (ECS Project No. 08-10205 dated August 29, 2014). ECS identified the following recognized environmental conditions (RECs) with respect to the subject site. • The presence of underground hydraulic lifts in the body shop. • The staining of the concrete in the vicinity of the used oil aboveground storage tank (AST) in the body shop. • The historical use as of the site as an auto repair facility/body shop since the 1960s. • The lack of on -site underground storage tank (UST) closure documentation. • ECS considered the closed incident associated with the auto facility north of the site to be a Controlled REC (CREC) due to the Notice of Residual Petroleum as part of the incident closure. However, the former paint thinner USTs and the lack of UST closure documentation associated with this facility was considered a REC of the site. • A former gasoline service station located across Highway 74 adjacent to the site to the east. • A closed UST incident was located at the former car wash on the southeastern portion of the site; however sampling data from UST closure was not available. Based on a potential real estate transaction and in an effort to determine if the site had been adversely impacted by the RECs identified during the Phase I ESA, ECS was contracted to conduct an assessment of the site. ECS conducted a Soil and Groundwater Assessment at the site (ECS Project No. 08-10205-A, dated October 3, 2014) to address the above mentioned RECs. The sample locations for this assessment are shown on Figure 3 and 4. Based on the results of the soil and groundwater assessment, ECS concluded the following: • A release had occurred from three hydraulic lift tanks (Tables 1 and 2). Based on the results of the assessment, ECS recommended the following: • Removal of the underground lifts and remediation of impacted soil. Limited Site Assessment Report Former Keifer Collision 4800 East Independence Boulevard, Charlotte, Mecklenburg County, North Carolina ECS Project No. 08-10205-D August 21, 2015 • Install and sample two wells in the area of GW-2. The additional assessment indicated that exceedances of NC2LGWQS in GW-2A appear related to residual petroleum contamination from the former closed UST incident in this location. The concentrations do not exceed the applicable DWM Non -Residential Vapor Intrusion Screening levels or GCLs. The MTBE concentration in sample GW-213 may have originated from the adjacent gasoline service station across Highway 74 to the east based on groundwater flow and historic groundwater data for this facility. This contamination was determined to be consistent with the previous release from the UST and also from an off -site source, and further assessment of this area was not recommended. This area is not included in this report and was included as an attachment to the Initial Abatement Action Report (IAAR). Based on these findings, Sifen Incorporated requested ECS oversee the removal of the underground lifts and impacted soil in the vicinity of the lifts and collect confirmatory soil samples. Approximately 231 tons of petroleum impacted soil was removed from the site for off -site disposal in January 2015. Due to depth constraints or structural limitations, complete removal of impacted soil was not possible in some of the areas. ECS submitted an IAAR to the North Carolina Department of Environment and Natural Resources (NCDENR) on March 11, 2015. A copy of the Soil and Groundwater Assessment Report and the report of additional groundwater assessment of the closed UST incident was included with the IAAR. The NCDENR issued a letter based on the IAAR requesting that a Limited Site Assessment (LSA) be conducted. Based on this letter, ECS was contracted to conduct the LSA sampling and prepare this report. 3.0 SITE CHARACTERISTICS: The subject site consists of an approximate 5.51 acre parcel of land that is currently developed with an automotive dealership (the former Keffer Collision Center) and is located at 4800 East Independence Boulevard in Charlotte, Mecklenburg County, North Carolina (Figures 1 and 2). The site is identified as Mecklenburg County Parcel Identification Number 16301305. According to the Mecklenburg County Online GIS Department, the site is currently owned by Wilson 301, LLC whom recently acquired the property from Richard W. Keffer Jr. and Constance O. Keffer. The subject site is improved with three buildings. The first building is an approximate 28,071 square foot structure that is utilized as offices and body shop and was constructed in 1968. The second building is an approximate 7,546 square foot building that is utilized as storage and the automobile paint spray booth and was constructed in 1986. The third building is an approximate 9,632 square foot building that is currently vacant and was constructed in 1968. The site is located in an area that can generally be described as residential/commercial. As determined from the USGS Topographical Map, Charlotte East, North Carolina (dated 1967; revised 1988) and Mint Hill (dated 1993), North Carolina Quadrangles, the subject site is situated approximately 740-750 feet above mean sea level with topography sloping to the southwest. East Independence Boulevard is located along a ridgeline that acts as a surface water drainage divide. No structures or water bodies are depicted on the site. Based on a review of the topographic map and observations of general area and site topography, FA Limited Site Assessment Report Former Keffer Collision 4800 East Independence Boulevard, Charlotte, Mecklenburg County, North Carolina ECS Project No. 08-10205-D August 21, 2015 surface run-off would be expected to flow to the southwest toward with areas to the northeast across Independence Boulevard considered topographically upgradient. The subject site is located within the Charlotte Belt of the Piedmont Physiographic Province. The soils encountered in this area are the residual product of in -place chemical weathering of rock presently underlying the site and/or historic depositional events. In general, shallow unconfined groundwater movement within the overlying soils is controlled largely by topographic gradients. However, as the groundwater percolates downward, it becomes controlled by the subsurface geologic conditions. Thus, the direction of groundwater movement in the deeper aquifers may not be consistent with the reflecting topography. Surface waters primarily recharge shallow aquifers by infiltration along higher elevations. Once in the shallow aquifer, the groundwater typically discharges into streams or other surface water bodies at lower elevations. The depth of the shallow water table is transient and can vary with seasonal fluctuations in precipitation. Groundwater movement in the shallow aquifer is generally from higher to lower elevations. As such, shallow groundwater is expected to flow generally to the southwest on the southwest side of Independence Boulevard. Based on the presumed groundwater flow direction, properties located to the northeast appear to be upgradient relative to the site. However, regional influences may have an impact on groundwater flow. The actual groundwater flow direction cannot be determined without site -specific information obtained through the installation of groundwater monitoring wells. 4.0 RISK CLASSIFICATION AND LAND USE Submit the following questionnaire in its entirety.

Limited Site Assessment Report Former Keffer Collision 4800 East Independence Boulevard, Charlotte, Mecklenburg County, North Carolina ECS Project No. 08-10205-D August 21, 2015 5.0 RECEPTOR INFORMATION ECS conducted a water supply well survey within a 1,500 foot radius of the source area. The survey was conducted by performing a driving and walking reconnaissance, interviews with City of Charlotte personnel, and distribution of water supply well questionnaires to owners of properties located within 500 feet of the source area, concerning water supply and usage. Based on the information obtained and discussed below, ECS did not identify properties that potentially contain water supply wells. Driving and Walking Reconnaissance ECS conducted a reconnaissance within the radius area for observations of water supply wells and evidence of municipal supplied water availability (water meters, meter boxes, fire hydrants, etc.). ECS did not observe evidence of water supply wells. Municipal water service was observed within the 1,500 foot radius of the source area. Interviews with City of Charlotte Personnel ECS inquired as to municipal water availability for the site and surrounding area. Based on discussions with Charlotte -Mecklenburg Utilities on April 9, 2012, municipal water is available to the site and surrounding area within the 1,500 foot radius of the source area. ECS also reviewed the Mecklenburg County well information system which did not identify water supply wells within the vicinity of the site. ECS submitted water supply well questionnaires to each property owner within a 500 foot radius of the source area. ECS sent water supply well questionnaires via certified mail to twenty-eight property owners. Six (4800, 4812, 4816, 4836, 4841, and 4805 Charleston Drive) were returned undelivered, and fifteen return receipts were received. As of the date of this report, four recipients (owners of 4905, 4911, and 4825 Charleston Drive) responded via telephone and indicated they are on city water and do not have a well. Five (4824, 4837, 4833, 4905, and 4825 Charleston Drive) completed questionnaires were returned. According to the information within the questionnaires, these properties did not contain water supply wells. A copy of the letter submitted, the recipient list, the certified mail receipts, and responses received are included in Appendix B. Summary of Water Usage Based on the available information, ECS did not identify wells used for drinking water within 1,500 feet of the source area (Figure 5). According to interviews with City of Charlotte personnel, municipal supplied water is available to the site and the area within a 1,500 foot radius of the source area. Water supply wells were not identified on the Mecklenburg County Well Information System. Surface Water An unnamed tributary of McMullen Creek is located approximately 1,000 feet to the southwest of the source area (Table 3). The tax map shows a drainage feature on the site, approximately 500 feet south of the source area. This was not observed during the site reconnaissance, and appears related to the sewer system which is located in that approximate area. Limited Site Assessment Report Former Keller Collision 4800 East Independence Boulevard, Charlotte, Mecklenburg County, North Carolina ECS Project No. 08-10205-D August 21, 2015 Wellhead Protection Areas The site is not located in a drinking water assessment area, and no public water supplies were identified as determined from the NCDENR Division of Water Resources Public Water Supply Section. Deep Aquifers in the Coastal Plain Phvsiographic Region The site is not located within the Coastal Plain physiographic region as designated on the map entitled "Geologic Map of North Carolina" published by the Department in 1985. Subsurface Structures Several subgrade structures consisting of natural gas, water, sewer, and electrical lines were identified on the site (Figure 2). Based on their depths, location, and observations at the site as compared to the identified impacted area, the identified subsurface structures do not have the potential to be conduits for contaminant transport. Land Use Property Owners and Occupants As contamination in groundwater was not detected above North Carolina 2L Groundwater Quality Standards (NC2LGWQS) contamination is not expected to migrate off -site. Table 4 is a summary of nearby property owners. Sensitive Land Use Features ECS did not identify features sensitive to impact from the release (schools, daycare centers, nursing homes, hospitals, playgrounds, parks and recreation areas, churches, camps and other places of assembly) within 1,500 feet of the source of the release. Site Geology and Hvdrogeologv The site is located within the Charlotte Belt of the Piedmont Physiographic Province as described in Section 3.0 of this report. Soils consisted of dense silty sands. Boring logs from well installation are included in Appendix A. Groundwater was encountered between 17.6 and 22.5 feet below ground surface (bgs) (Table 5). Since there is insufficient groundwater data for the site, the groundwater flow direction cannot be determined at this time. Based on surface topography, the shallow groundwater is assumed to flow to the southwest toward an unnamed tributary of McMullen Creek (Figure 1). 6.0 FIELD ACTIVITIES On July 7, 2015, ECS personnel observed the advancement of soil boring MW-1 and MW-2 in the vicinity of previously identified petroleum impacts (Figure 4). The borings were advanced by Carolina Soil Investigations, LLC (CSI), a North Carolina certified driller, using a Geoprobe© drill rig with auger capabilities. A boring log, well construction diagram and record were prepared and are included in Appendix A. Soils were screened with a PID and samples collected based on field screening in 5 foot intervals beneath the former excavation backfill material. After terminating the borings at approximately 35 feet below ground surface (bgs), the permanent groundwater monitoring wells (MW-1 and MW-2, Figure 4) were installed. Each well was constructed with 2-inch I.D. Schedule 40 PVC flushed -threaded casing and screen. The PVC Limited Site Assessment Report Former Keffer Collision 4800 East Independence Boulevard, Charlotte, Mecklenburg County, North Carolina ECS Project No. 08-10205-D August 21, 2015 screen and casing were lowered to the bottom of the borehole. A 15-foot length of slotted well screen with machined 0.010-inch slot widths and threaded bottom plug was installed at the bottom of the well. A solid section of PVC casing was placed above the screened interval and extended to a point approximately 6 inches below the ground surface. The top of the casing was fitted with an expandable lockable cap. The annular space around the well was filled with washed fine filter sand to approximately two feet above the top of the screen. A minimum 2-foot thick seal of bentonite pellets was placed immediately above the sand pack. The top of the well casing was equipped with a lockable, water -tight well plug. The well was finished with concrete and a flush -mount steel manhole was installed in a concrete pad to protect the well. A monitoring well construction diagram was prepared for the well and is included in Appendix A. 6.1 Soil Sampling Soil samples were collected at 16, 21, and 26 feet below ground surface (bgs) in MW-1 and MW-2, as fill extended to approximately 15 feet bgs and saturated soils were encountered at approximately 27 to 30 feet bgs (Table 5 and 6). Soil samples were analyzed for semi -volatile organic compounds (SVOCs) using EPA Method 8270, and Massachusetts Department of Environmental Protection (MADEP) extractable petroleum hydrocarbons (EPH). Hydrocarbons in the C11 to C12 aromatic range were detected at concentrations above North Carolina Soil -to -Groundwater Maximum Soil Contaminant Concentration (MSCC) in MW-1-A. COncentrations did not exceed the Residential or Commercial MSCC. Concentrations in deeper samples between MW-1A and the water table and in MW-2 did not exceed the MSCCs. The results are summarized in Table 7 and the lab results included in Appendix C. 6.2 Groundwater Sampling On July 8, 2015, after installation and allowing for recovery of water levels, the wells were checked for evidence of free phase petroleum product using a bailer. Free phase petroleum product was not detected. Water was purged from the wells and a groundwater samples were collected from MW-1 and MW-2. Groundwater samples were analyzed for SVOCs and MADEP EPH. Several SVOCs and MADEP EPH compounds were detected at concentrations above laboratory reporting limits; however the concentrations are not above the NC2LGWQS. The results are summarized in Table 8 and the lab results included in Appendix C. 7.0 CONCLUSIONS AND RECOMMENDATIONS Based on the results of the investigation, ECS has the following conclusions • ECS previously observed the excavation of approximately 231 tons petroleum -impacted soils from the location of the former underground lifts. Groundwater was not encountered during soil excavation activities. Due to site constraints, petroleum contaminated soil above residential criteria is still present near two former underground lifts, though it does not exceed the commercial risk levels. Based on the intended use of the site for commercial uses, and soils being under a building with a concrete slab there is no risk of exposure to the public to these soils, provided there is no further excavation in this area. • Based on results of groundwater sampling, the former hydraulic lifts have not resulted in impacts to groundwater above NC2LGWQS. Since there is no record of groundwater Limited Site Assessment Report Former Keffer Collision 4800 East Independence Boulevard, Charlotte, Mecklenburg County, North Carolina ECS Project No. 08-10205-D August 21, 2015 impacts above NC2LGWQS, no water supply wells were identified within 1,000 feet of the source area, and municipal water is available to the site and surrounding area, ECS does not recommend additional assessment. • ECS recommends that this report be submitted to the NCDENR-Mooresville Regional Office for their consideration for no additional assessment and closure of the incident pending filing of a Notice of Residual Petroleum (NORP). 8.0 QUALIFICATIONS The activities and evaluative approaches used in this assessment are generally consistent with those normally employed in assessments and remediation projects of this type. ECS' evaluation of site conditions has been based on our understanding of the project information and the data obtained during our field activities.

Please be advised that Mr: Keffer sold the referenced property on December 17, 2014, to Wilson 301, LLC, per the enclosed Deed. Prior to the purchase, Wilson 301, LLC engaged in ECS Carolinas, LLP to perform an environmental investigation of the property, and it is our understanding that they were satisfied with the results of said investigation, hence their ultimate purchase of the property. My assumption is that the initial Abatement Action Report received by your office referenced in your letter was performed by ECS on behalf of Wilson 301, LLC. As Wilson 301, LLC is the owner of the property and presumably prepared the report in question, please contact them to discuss this matter.

According to the report L-1, L-3 and LA soil samples had exceeded soil -to -groundwater standards but I couldn't tell if these areas were subsequently excavated as part of the IAA work (Figure 4 of the report shows L-3 outside the area excavated, and the figure doesn't show where L-1 and LA were relative to the excavations)? L-1 and LA were excavated and were located in excavations 2607 and 2605. L-3 was excavated and was located in excavation 2611. The location shown as L-3 on Figure 4 was actually L-2. What were the dimensions of the final excavation pits for the three leaking lifts? The approximate dimensions were as follows: 2611 — 12'xl2'xl4'deep 2605—10'xl2'x14'deep 2607—13'xl5'xl4'deep 14 feet was the maximum feasible excavation depth due to the garage height and equipment that could fit inside the garage. Have you reported the arsenic levels to the Inactive Hazardous Sites branch? This was the first report submitted. The only know source at the site is those discussed in the report and these samples were adjacent to the underground lifts which is the only known source in this area. I could not find groundwater sampling results for the GW-2A and GW-213 wells in the report... GW-2A & GW-2B were on the opposite end of the site related to other areas at the site and not near the items addressed in this report. Specifically they addressed an off -site source and confirming groundwater concentrations relative to a closed LUST incident on the other portion of the site, several hundred feet away from the garage. It was detailed in a separate report to the client which is attached. Once I have this information I will complete my review of the report. Thanks for your help, Brett Brett Morris - Brett.
