Laboratory Analytical Reports and Chain -of -Custody Records 'J MCADAMS LIMITED PHASEII ESA REPORT > LCG-16010 1.0 INTRODUCTION The John R McAdams Company (McAdams) performed this Limited Phase II Environmental Site Assessment (Limited Phase II ESA) on the Former Crown Honda & Volvo Property located at 1730 Fordham Boulevard, Chapel Hill, Orange County, North Carolina (herein referred to as the "subject site"). The subject site consists of three contiguous parcels identified as Orange County Property Identification Numbers (PINS) 9799-36-6631 (Tract 1), 9799-36-7662 (Tract 2), and 9799-46-1235 (Tract 3). The subject site is also identified as "Crown Honda II" by the North Carolina Brownfields Program (NCBP) under Project ID 20077-16-74. The subject site is depicted on the topographic map and site features map presented as Drawings 1 and 2, respectively. The Phase II Assessment activities were conducted in general accordance with the Limited Phase II Assessment Workplan (Revision 1), dated December 21, 2017 that was approved by Mr. Kelly Johnson of the NCBP. Note that the Limited Phase II Assessment Work Plan provides a summary of previous historical environmental investigations performed in conjunction with the closure of hydraulic lift systems and an oil water separator. The purpose of the Limited Phase II ESA was to obtain additional information to further evaluate environmental risk to support safe reuse of the site and to assist in management of soil and water generated during construction as described in the Environmental Management Plan (EMP) that was approved by the NCBP on December 12, 2017. Specific objectives of this Limited Phase II include 1) a determination if site soils are impacted by contaminants at proposed temporary construction stormwater ponds, permanent underground stormwater detention and sand filter units, and utility cuts for new construction; and 2) identification of depth to groundwater in proposed surface grade cut areas, so plans can be developed to evaluate groundwater quality and manage groundwater in excavations during construction (if present). The location of these proposed construction features is presented on Drawing 3. A third objective included an evaluation of a potential underground storage tank (UST). A UST was suspected when a vent pipe was discovered in an exterior storage area by McAdams during a March 2017 site visit. The vent was observed between the former waste oil UST and former new oil USTs (that were removed in 1998) located near the southeast corner of the current building. Assessment activities for this Limited Phase II ESA included a geophysical evaluation of the suspect area. The approximate location of the potential UST is depicted on Drawing 2. An area of mounded soils was identified in the vicinity of a former residential home located in the southeastern portion of the site along Legion Road during a historical Phase I assessment. The mounds were suspected to be soil and associated debris from the demolition of the residence and construction of the Crown automotive sales and repair facility. A fourth objective of this Limited Phase II ESA included the performance of a geophysical survey, the advancement of test pits and the installation of monitoring wells to evaluate the type of soil and debris, if there was evidence of current/former heating oil USTs/above ground storage tanks (ASTs), and associated potential impacts. The location of mounded soils is depicted on Drawing 2. creating experiences through experience 1of 10 �� MCADAMS LIMITED PHASEII ESA REPORT > LCG-16010 The NCBP also requested the collection of a groundwater sampled under the footprint of proposed Building 2 for environmental risk calculation purposes. Groundwater sampling requirements to meet this requirement are provided in the following sections of this report. Because redevelopment plans include proactive mitigation with the installation of a vapor intrusion mitigation system (VIMS), additional assessment in these areas including a vapor intrusion assessment of residual chlorinated solvents and other volatile organic compounds, was not performed as part of the Limited Phase II ESA scope of work. Please refer to the approved VIMS design prepared by McAdams, dated February 27, 2018, for additional details. 2.0 SUMMARY OF ASSESSMENT ACTIVITIES Limited Phase II activities were performed on February 27 through March 7, 2018. Prior to fieldwork being conducted, a Health and Safety Plan (HASP) was prepared by McAdams, and North Carolina 811 was contacted to locate utilities to the property boundary. 2.1 Utility Clearing and Geophysical Survey On February 27, 2018 personnel from McAdams and Geo Solutions Limited, Inc. (Geo Solutions) of Conway, North Carolina cleared boring locations of utilities using ground penetrating radar (GPR), electromagnetic (EM) and radio - detection (RD) methods. This information was used to finalize proposed sample locations. Geo Solutions utilized GRP and EM to survey the former storage area and suspected UST location for the presence of a previously unidentified UST. Geo Solutions also conducted an EM survey of the buried debris area to characterize the extent and type of buried waste. The results of these surveys are discussed in Section 4.1. A geographic representation of the EM survey results for the debris area is included in Appendix A. 2.2 Test Pit Soil Assessment Quantex, Inc. (Quantex) of Clayton, North Carolina mobilized a mini-trackhoe to the site on February 27, 2018 to excavate sixteen shallow test pits (TP-1 through TP-16) in the mounded soil area in the eastern portion of the site (Drawing 4). Test pits were advanced until native soils were encountered. A Photoionized Detector (PID) unit was used to screen soils from the excavation bucket during to measure total volatile concentrations and soils were visually examined for evidence of impacts. Soils were also geologically classified in general conformance with the Unified Soil Classification System (USCS). A summary of the PID readings and soil classification is provided in the Test Pit Logs provided in Appendix B. Five soil samples were selected for laboratory analysis based on field screening results from TP-3, TP-6, TP-9, TP-11, and TP-13. One laboratory blind duplicate sample, from TP-13, was also submitted for laboratory analysis. Soil for each sample was placed into laboratory -supplied containers, packed into an ice -filled cooler, and transported under chain - of -custody to Prism Laboratories, Inc. (Prism) in Charlotte, North Carolina. The five test pit soil samples were analyzed for volatile organic compounds (VOCs) using United States Environmental Protection Agency (EPA) Method 8260B, semi - volatile organic compounds (SVOCs) using EPA Method 8270D (base neutrals and acid extractables [BNAs]), and creating experiences through experience 2 of 10 'J MCADAMS LIMITED PHASEII ESA REPORT > LCG-16010 Resource Conservation Recovery Act (RCRA) Metals using EPA Methods 6010D and 7471B. The laboratory report is provided in Appendix C and the results are discussed in Section 4.1 of this report. 2.3 Soil Boring Advancement and Soil Sampling On February 28, 2017, Quantex mobilized a track mounted Geoprobe° rig to advance eight soil borings (TMW-1 through TMW-8) (Drawing 4) utilizing direct push technology (DPT) to determine if site soils were impacted by contaminants at proposed construction features. Soil cores were collected using five-foot long, two-inch diameter, macro -core samplers. Soil from each boring were field screened for the presence of potential impacts using a PID in conjunction with field observations. Borings were also geologically classified in general conformance with the USCS. Refer to Appendix B for Soil Boing Logs summarizing PID readings, field observations, and geology. As shown on Drawing 4, TMW-1 and TMW-5 were advanced in the location of the proposed temporary construction ponds. TMW-2 and TMW-6 were advanced in the location of the proposed Stormwater Detention Boxes. TMW-3 and TMW-4 were advanced in the location of proposed utility cuts. TMW-7 and TMW-8 were installed in the area of buried debris. Soil samples, collected as summarized in Table 1 below, were placed directly into laboratory -supplied containers and submitted under chain -of -custody to Prism for analysis of VOCs using EPA Method 8260B, SVOCs using EPA Method 8270D (BNAs), and RCRA Metals using EPA Methods 6010D and 7471B. The laboratory test report is provided in Appendix C and the test results are discussed in Section 4.2 of this report. Soil samples were not collected from TMW-7 and TMW-8 for laboratory analysis because test pit samples were utilized to characterize soil in this area. Table 1.

Solid stem augers were utilized to extend each boring until refusal was encountered. Auger refusal (most likely on partially weather rock) was encountered in each of the borings between 11 and 25 feet BLS. creating experiences through experience 3 of 10 �� MCADAMS LIMITED PHASEII ESA REPORT > LCG-16010 Because monitoring wells TMW-7 and TMW-8 were found to be dry following installation, and following NCDEQ NCBP approval, on March 5, 2018, Quantex mobilized an air rotary drilling to install temporary monitoring well TMW-9 within partially weathered rock adjacent to TMW-8 (Drawing 4). The dry monitoring wells served their purpose for documenting that groundwater within the underlying Triassic Basin geologic formation (see Section 3.2 for additional information regarding site geology) would not be encountered during construction Temporary monitoring wells were constructed of 2-inch diameter, schedule 40 polyvinyl chloride (PVC) with 0.010 slotted well screen lengths of no less than five feet. Temporary Monitoring Well Construction Logs are provided in Appendix B. Following installation, depth to groundwater was measured at each well using a water level meter. Groundwater depths are summarized in Table 2. 2.5 Groundwater Sampling On March 5 and 8, 2018, McAdams utilized an electronic water level meter to gauge each well and observed all wells to be dry except for TMW-2 and TMW-9. The dry wells met the objective of determining if groundwater within the underlying Triassic geologic formation (see Section 3.2 for additional information regarding site geology) would be encountered during construction. These two wells containing groundwater were developed and purged for sample collection by removing four standing well -volumes of water. McAdams collected a groundwater sample from well TMW-2 using a peristaltic pump and dedicated tubing on March 5, 2018. A groundwater sample was collected from well TMW-9 using a dedicated bailer and nylon twine on March 8, 2018 as the depth to groundwater did not permit the use of a peristaltic pump. One laboratory blind duplicate sample was collected from well TMW-2 for quality assurance and quality control. Groundwater was decanted directly into laboratory supplied bottle ware, placed on ice and submitted under chain - of -custody to Prism for analysis of VOCs by EPA Method 6200B, SVOCs by EPA Method 625 (BNAs), and RCRA Metals by EPA Method 6010D and 7470A. Groundwater sample laboratory reports are provided in Appendix C. Groundwater sample results are discussed in Section 4.3 of this report. 2.6 Temporary Monitoring Well Survey Equipment and personnel from Pennoni (a North Carolina Registered Land Surveyor [RLS]) mobilized to the site on March 6, 2017 to survey the newly installed temporary wells and reference them to the existing monitoring well network. The lateral location of each well was referenced to the North Carolina State Plane and the elevation of the top of each well casing was measured and referenced to the North American Vertical Datum of 1989. Temporary monitoring well survey data is summarized in Table 2. creating experiences through experience 4 of 10 �� MCADAMS LIMITED PHASEII ESA REPORT > LCG-16010 Well elevation data was obtained to determine groundwater elevations and the elevations of the bottom of dry monitoring wells. In turn, this information can be used by construction personnel to evaluate groundwater elevations in relation to proposed construction elevations. 2.7 Site Clean-up Investigation -derived waste (IDW) including soil cuttings from TMW-1 through TMW-9 and purge water from TMW- 2 and TMW-9 were returned to the original soil boring or spread on the ground in accordance with NCDEQ guidelines. The IDW will be managed under the EMP during site construction. 3.1 Topography and Surface Water Drainage According to United States Geological Survey (USGS) Topographic Quadrangles of Chapel Hill, North Carolina site elevations range from approximately 290 to 325 feet above mean sea level (msl) (Drawing 1). Based on local topography surface water is expected to flow southeast in the general direction of Booker Creek. 3.2 Site Geology According to the North Carolina Geological Survey Section of the North Carolina Department of Natural Resources and Community Development Geology of North Carolina (1985) map, the site is in the Piedmont Physiographic Province. Underlying bedrock of the subject site consists of conglomerate, fanglomerate, sandstone, and mudstone of the Chatham Group. The Chatham Group is part of the Triassic Basins of the Newark Supergroup. Overlying soils consist of saprolite, derived from in -situ weathering of the underlying rock. As presented in soil boring logs (Appendix B) soil at the site generally consists of surficial clay that transitions to silty clay with depth. Test Pit logs indicate that buried debris in the mounded area consists primarily of tires and construction debris including asphalt, concrete, and bricks on top of native material. The thickness of the fill material was observed to vary from approximately one to three feet. 3.3 Site Hydrogeology Depth to groundwater in TMW-2 and TMW-9 as measured on March 5, 2018 was 18.19 feet below land surface (BLS) and 38.30 feet BLS, respectively (Table 2). Groundwater was not encountered in wells TMW-1, TMW-3, TMW- 4, TMW-5, TMW-6, TMW-7, and TMW-8. As previously discussed, the presence of dry wells provides useful information since groundwater within the underlying Triassic basin is often encountered under confined conditions making it difficult to determine the actual depth to groundwater at the site. Based on our limited review of the topography and water features, shallow groundwater is expected to flow southeast towards Booker Creek. creating experiences through experience 5 of 10 �� MCADAMS 4.0 LIMITED PHASE II ESA ANALYTICAL RESULTS LIMITED PHASEII ESA REPORT > LCG-16010 The following sections provide a summary of the Limited Phase II ESA results. As described in Sections 4.2 and 4.3 and summarized in Table 2, soil analytical results have been compared to NCDEQ Inactive Hazardous Sites Branch (IHSB) Preliminary Soil Remediation Goals (PSRGs). Groundwater analytical results, summarized in Section 4.4 and Table 3, were compared to the 15A North Carolina Administrative Code (NCAC) 02L .0202 Groundwater Quality Standards (21- Standards) and the NCDEQ Division of Waste Management (DWM) Vapor Intrusion Residential and Non -Residential Groundwater Screening Levels (VI GWSLs). Laboratory analytical reports and chain -of -custody records for soil and groundwater samples are provided in Appendix C. 4.1 Geophysical Survey Results The geophysical survey of the storage area where a potential UST was suspected was inconclusive. A subsurface anomaly measuring approximately 4 feet by 8 feet was observed in the area however the presence of rebar within the concrete floor slab caused interference making further characterization difficult. This area will need to be further investigated to determine if a UST is present during building demolition per EMP requirements. As depicted in EM survey (Appendix A), the area of buried debris in the eastern portion of the site consisted primarily of non-metallic material, inferred to be construction debris from the former residence and construction of the rear parking area of the former Crown property. No evidence of USTs/ASTs was observed during the geophysical survey. However, the potential presence of a heating oil UST should still be considered during site grading work at the location of the former residence. The location of the former residence can be identified in the field by the cinderblock foundation. 4.2 Test Pit Soil Analytical Results As discussed in Section 2.2, test pit soil samples were collected to characterize soil in the eastern portion of the site in the area of buried debris. Five soil samples were selected for laboratory analysis based on field screening results. Below is a summary of soil results by compound suite. VOCs • Acetone was detected in TP-13 and the corresponding duplicate sample (Dup-1) at estimated concentrations below the respective Residential and Protection of Groundwater PSRGs. • Outside of Acetone, no other VOCs were detected in any soil samples collected from the test pits. • Acetone is a common sampling/laboratory artifact. SVOCs • Benzo(a)pyrene (typically found in asphalt, oil or waste oil) was detected at an estimated concentration above its respective Residential and Protection of Groundwater PSRGs in TP-11. The estimated concentration did not exceed the respective Industrial/Commercial PSRG. creating experiences through experience 6 of 10 �� MCADAMS LIMITED PHASEII ESA REPORT > LCG-16010 • Several other SVOCs typical of asphalt and petroleum were detected in TP-11 at (estimated and actual) concentrations below their respective Residential and Protection of Groundwater PSRGs, including: Benzo(a)anthracene, Benzo(b)fluoranthene, Chrysene, Phenanthrene, and Pyrene. • Benzoic Acid was reported in both TP-6 and TP-11 at estimated concentrations below the respective Residential and Protection of Groundwater PSRGs. This compound can be naturally occurring in plants and is potentially attributed to the organic material in the soil samples. • No other SVOCs were detected in samples TP-3, TP-6, TP-9, and TP-13. Metals • Barium, chromium (total), and lead were detected at concentrations below their respective Residential and Protection of Groundwater PSRGs in each of the test pit soil samples. • Arsenic was detected at concentrations above its respective Residential PSRG in each of the test pit soil samples. The detected concentrations also exceeded the Industrial/Commercial and/or Protection of Groundwater PSRG in TP-3, TP-6, and/or TP-11. 4.3 Soil Boring Analytical Results As discussed in Section 2.3, borings were advanced and samples were collected to determine if site soils were impacted by contaminants at proposed construction features. As summarized in soil boring logs (Appendix A), no evidence of potential impacts was identified using field screening methods. One soil sample from each of the six borings was selected for laboratory analysis based on field screening results. Below is a summary of soil results by compound suite. VOCs • Benzene was detected in TMW-4 (5-9) at a concentration below the respective Residential and Protection of Groundwater PSRGs. • Benzene is a constituent commonly found in gasoline. • No other VOCs were detected in soil samples collected from the soil borings. SVOCs • No SVOCs were detected in soil samples collected from the soil borings. Metals • Barium, chromium (total), and lead were detected at concentrations below their respective Residential and Protection of Groundwater PSRGs in each of the soil boring samples. • Mercury was detected in sample TMW-3 (8-11) at a concentration below its respective Residential and Protection of Groundwater PSRGs. Silver was detected in samples TMW-1 (1-5), TMW-2 (5-10), and TMW-4 (5-9) at concentrations below its respective Residential and Protection of Groundwater PSRGs. creating experiences through experience 7 of 10 �� MCADAMS LIMITED PHASEII ESA REPORT > LCG-16010 • Arsenic was detected at concentrations above its respective Residential PSRG in each of the soil boring samples. The detected concentrations also exceeded the Industrial/Commercial and/or Protection of Groundwater PSRG in TMW-1 (1-5), TMW-2 (5-10), TMW-4 (5-9) and/or TMW-6 (4-8). 4.4 Groundwater Analytical Results Two groundwater samples (TMW-2 and TMW-9) were analyzed for the presence of VOCs, SVOCs, and RCRA Metals to determine if impacted groundwater would be encountered during construction activities. Results of the groundwater sampling event revealed the following: VOCs • MTBE was detected in TMW-2 and the corresponding duplicate sample (DUP-GW) at concentrations below the respective 2L Standards and the NCDEQ DWM Residential VI GWSLs. MTBE is a commonly associated with gasoline. • Acetone was detected in the duplicate sample (DUP-GW) at an estimated concentration below the respective Residential and Protection of Groundwater PSRGs. Acetone reported at this concentration and the lack of a detection in the corresponding sample TMW-2 indicates that this is likely attributable to laboratory contamination, and not indicative of groundwater impacts. • No other VOCs were reported in groundwater samples submitted for analysis. SVOCs • No SVOCs were reported in groundwater samples submitted for analysis. Metals • Barium, chromium (total), and lead were detected at concentrations (actual and estimated) below their respective 2L Standards in both TMW-2 and TMW-9. • No other metals were reported in groundwater samples submitted for analysis. 5.0 FINDINGS Based on the results of this Limited Phase II Assessment McAdams offers the following findings: • Interference from rebar was experienced during the geophysical survey of the storage area where a potential UST is located, however an anomalous area measuring 4 feet by 8 was observed. As a result of interference, the survey results were found to be inconclusive. • The geophysical survey and test pitting activities in the area of buried debris in the eastern portion of the site revealed the presence of non-metallic materials including asphalt, concrete, and bricks likely associated with demolition of the former residence and construction of the former Crown property. The thickness of creating experiences through experience 8 of 10 �� MCADAMS LIMITED PHASEII ESA REPORT > LCG-16010 the fill material was observed to vary from approximately one to three feet. No evidence of USTs/ASTs was observed during the geophysical survey or test pitting activities. • Analytical results of test pit sample TP-11, indicated the presence of polyaromatic hydrocarbons (PAHs) commonly associated with the presence of asphalt, and petroleum. Benzo(a)pyrene at an estimated concentration was the only PAH reported above its respective Residential and Protection of Groundwater PSRGs in TP-11. • Soil boring assessment results Indicated the presence of benzene in sample TMW-4 (5-9) at a concentration below both the Residential and Protection of Groundwater PSRGs. • Test pit and boring soil sample results indicated the ubiquitous presence of metals across the site. The low concentrations observed indicate that these metals are likely attributable to naturally occurring conditions. • Reported groundwater elevations in TMW-2 and TMW-9 were measured below proposed construction depths, additionally the bottom of the well screen in dry wells were measured to extended beyond the proposed maximum construction depth of 15 feet BLS. • No compounds were detected in groundwater at concentrations exceeding their respective 2L Standards or the NCDEQ DWM Residential VI GWSLs. 6.0 CONCLUSIONS AND RECOMMENDATIONS The objective of this Limited Phase II was to 1) to determine if site soils were impacted by contaminants at proposed stormwater features and utility cuts; 2) to determine depth to groundwater at these proposed features, so plans can be developed to evaluate groundwater quality and manage groundwater in excavations during construction (if present; 3) evaluate the potential UST in the rear storage area; 4) to evaluate the type of soil and debris, and for evidence of current/former heating oil USTs/ASTs and associated potential impacts within the area of mounded soils, and; 5) collect a groundwater sample under the footprint of Building 2 for NCBP environmental risk calculation purposes Overall, no evidence of gross impacts was observed during our assessment of soil and groundwater which is consistent with previous Phase II assessment results conducted by others. Results of our investigation indicate that soils are not impacted above applicable residential/protection of groundwater regulatory levels in the location of proposed construction features, including temporary construction stormwater ponds, permanent underground stormwater detention and sand filter units, and utility cuts. Additionally, groundwater was not encountered within temporary monitoring wells above the proposed depth of these features, indicating that groundwater will likely not be encountered during construction. Although the existence of a UST within the rear storage area could not be confirmed, as established in the Environmental Management Plan (EMP) approved by the NCBP on December 12, 2017, personnel from McAdams will be onsite during removal of the building slab and will examine the area for the presence of a tank. If a UST is found, it can be removed under previsions established under the EMP. creating experiences through experience 9 of 10 �� MCADAMS LIMITED PHASEII ESA REPORT > LCG-16010 The geophysical survey and the advancement of test pits within the area of mounded soil revealed that debris in this area primarily consist of non-metallic materials including asphalt, concrete, and bricks. A small area of soil, likely impacted by asphalt and petroleum, was encountered within one of these debris piles. Although the source of this contamination could not be confirmed, this soil can be managed under the established provisions of the EMP. Although no evidence of a UST was found associated with the former residence in the vicinity of proposed Building 2, the potential presence of a UST should be considered during construction grading operations as a precaution. Geophysical, soil, and groundwater data collected as part of this Limited Phase II ESA indicate that the methods and practices of managing environmental conditions during site redevelopment as outlined in the EMP will be sufficient. McAdams does not recommend additional environmental assessment or mitigation practices beyond those established in the EMP. 7.0 REFERENCES North Carolina Department of Environmental Quality (NCDEQ), Inactive Hazardous Sites Branch (IHSB), Preliminary Soil Remediation Goals Table, last updated in February 2018. 15A North Carolina Administrative Code (NCAC) 02L .0202 Groundwater Quality Standards, February 22, 2016.
