The site was formerly used as a residence and is currently developed with one vacant residential structure and one cellular tower with supporting infrastructure. Land use at the subject site has been confirmed by aerial photographs back to 1949, when the northern portion of the site was used for agricultural purposes. The remainder of the subject site has been largely agricultural or undeveloped until a residential structure was added in 1957 and a cell tower was constructed by approximately 2002. This telecommunications tower is located near the eastern property boundary within a fenced, restricted facility that is subject to a long-term lease with the property owner. Mid -Atlantic completed a Phase I Environmental Site Assessment (PESA) for the subject site in December 2017 and during this assessment Mid -Atlantic noted evidence of a former above ground storage tank (AST) at the rear of the vacant house on the subject site which had likely contained heating oil. The former property owner, Mr. Wong, confirmed the former presence of a heating oil AST. Staining on the support structures for the AST and on the rear wall of the house suggested the possibility of a release. Mid - Atlantic collected and tested three soil samples behind the house in the vicinity of the former heating oil AST, and produced the Letter Report of Soil Sampling Results, 3612 Davis Drive. The report, produced in November 2017 confirmed the release of petroleum contaminants but did not define the extent of impact. As part of the purchase and re -purposing of the site, CRP-GREP AA Overture Cary, LLC intends to obtain a Brownfields Agreement (BFA) under the North Carolina Brownfields Program. CRP-GREP AA Overture Cary, LLC contracted with Mid -Atlantic to perform additional assessment at the subject site. Mid -Atlantic developed a Phase 11 Work Plan outlining soil and groundwater sampling activities designed to address the data gaps identified by the Brownfield Program. This Work Plan was submitted to the Brownfields Program on February 18, 2019 and approved by the Program on February 27, 2019. The Phase II Work Plan proposed assessment of soil and groundwater in the vicinity of the former heating oil AST, the assessment of soil in the vicinity of two observed debris piles, and the assessment of soil and groundwater in the vicinity of the cellular tower and associated emergency generators. The opinions included herein are based on our experience and the information obtained during the study. This report is based on limited observations made on the dates noted using the procedures described herein. If additional information becomes available, we request the opportunity to review the information, reassess the potential environmental concerns and modify our conclusions and recommendations, if appropriate. Ift Mid Atlantic Engineering & Environmental Solutions Phase 11 Environmental Site Assessment Report April 25, 2019 Cary Overture Page 2 3612 & 3624 Davis Drive Cary/Morrisville, North Carolina 2.0 SUMMARY OF FIELD ACTIVITIES 2.1 Sampling Location Siting Mid -Atlantic identified five sampling locations as discussed in the Work Plan: the former location of heating oil AST on the back wall of the vacant house to assess petroleum release impacts; vicinity of the cellular tower to evaluate for the presence of contamination associated with facility operations; the locations of two debris piles to evaluate for potential release(s) of contaminates to the environment; and a background sample to evaluate naturally occurring metals concentrations in the local soil. On April 8, 2019 Mid -Atlantic marked the proposed soil boring and temporary monitoring well locations at the subject site. Additionally, as specified in the Work Plan, soil boring locations SB-1 through SB-3 and temporary monitoring well TMW-1 were chosen in the field around the former heating oil AST area using visual observation of the surrounding ground conditions. Boring SB-4 and TMW-2 had intended to be downgradient of the cellular tower emergency generators, as specified by the Work Plan; however, despite three relocation attempts, TMW-2 could not be installed due to auger refusal before reaching groundwater. Borings SB-5 and SB-6 were placed in areas of observed household debris piles. Boring BG-1 was placed in an undeveloped wooded area in order to analyze a representative background soil sample. Sample locations are shown on Drawing 2.1. On April 15, 2019, private utilities were located and marked by KCI Associates of North Carolina (KCI) in the areas of the proposed sampling locations. Several of the original site locations were not accessible with the Geoprobe and were either collected with a hand auger or relocated. The final locations of the soil borings and monitoring wells were placed to avoid the marked utilities and to be situated as close to the proposed sampling locations as could safely be managed. Mid -Atlantic does not anticipate that the relocation of these soil borings impacts the findings of this report. 2.2 Soil Boring and Sampling On April 15, 2019, under the supervision of Mid -Atlantic, Quantex Inc. (Quantex) used a Geoprobe 7822DT to advance seven soil borings at the designated locations (Drawing 2.1). Each boring was advanced using decontaminated equipment. Soil samples were collected via 5-foot macrocores for soil characterization and laboratory analysis. Soil was screened for the presence of volatile organic compounds (VOCs) using a Toxic Vapor Analyzer (TVA) 1000 photo ionization detector and flame ionization detector (PID/FID) in accordance with the procedures described in the Work Plan. Boring logs are provided in Appendix A. Mid Atlantic Engineering & Environmental Solutions Phase 11 Environmental Site Assessment Report Cary Overture 3612 & 3624 Davis Drive Cary/Morrisville, North Carolina April 25, 2019 Page 3 Seven soil samples from various depths were collected for laboratory analysis of VOCs, semi-VOCs (SVOCs), and RCRA Metals. Soil samples were shipped to Prism Laboratories, Inc. (Prism) in Charlotte, North Carolina for laboratory analysis as shown on the chain of custody record provided in Appendix B. 2.3 Monitoring Well Installation and Sampling On April 15, 2019, Quantex installed one temporary monitoring well, TWM-1, using 5-inch solid stem augers, at the location proposed in the Work Plan. The work was conducted under the supervision of a Mid -Atlantic field technician. The temporary well was constructed to 40 feet below ground surface with 2-inch diameter Schedule 40 PVC and 20 feet of well screen (as shown on the boring log provided in Appendix A). The well was developed upon completion using dedicated disposable bailers to remove particulates from the water column and improve the hydraulic connection between the aquifer and the well. Mid -Atlantic's technician sampled the temporary well and collected a water level measurement of 33.20 feet below land surface. The groundwater sample was shipped to Prism for laboratory analysis of VOCs, SVOCs, and metals as shown on the chain of custody record provided in Appendix B. Following sampling activities, the temporary well was abandoned by Quantex on April 15, 2019. A second temporary monitoring well, TMW-2, was specified in the Work Plan. However, the well boring for TMW-2 was relocated three times with auger refusal occurring from 4.5 to 7 feet below land surface on each event. These depths did not extend to below the estimated depth to groundwater and prevented the installation of temporary monitoring well TMW-2.

The laboratory analytical report and chain of custody record for the soil samples and groundwater samples are provided in Appendix B. The test results for soil samples were compared to the Unrestricted Health Based Preliminary Soil Remediation Goals (PSRGs), the Protection of Groundwater PSRGs, and the Industrial PSRGs. Groundwater samples were compared to the North Carolina Groundwater Quality Standards (NCGQS). Mid Atlantic Engineering & Environmental Solubons Phase 11 Environmental Site Assessment Report April 25, 2019 Cary Overture Page 4 3612 & 3624 Davis Drive Cary/Morrisville, North Carolina 3.1 Soil Analytical Data As summarized in Table 3.1, two VOCs were detected in five of the seven soil samples tested. These compounds were detected at estimated concentrations below the PSRGs. Acetone, one of the two compounds detected, is a common laboratory artifact. Of the six soil samples tested for the presence of SVOCs, one sample (SB-6) exhibited detectable concentrations. This sample, collected near a debris pile, exhibited six polynuclear aromatic hydrocarbons at estimated concentration below the PSRGs. Seven soil samples, including the background sample, were tested for the eight RCRA metals. Arsenic was detected above the Unrestricted Health Based PSRG in five of these samples. The Industrial PSRG was exceeded in two samples including the background sample. Arsenic is a metal that is found naturally occurring in North Carolina soils. According to the North Carolina Department of Agriculture and Consumer Services (NCDA), an average concentration of 4.5 mg/Kg of arsenic was detected in laboratory testing of 3,286 soil samples collected across North Carolina between 2005 and 2007 (NCDA, 2008). Furthermore, the EPA notes that arsenic concentrations typically range from 4 to 9 mg/Kg in most soils (EPA, 2003). According to the laboratory analysis, the arsenic concentrations detected in the soil samples collected from the subject site fall within levels believed to be found naturally in North Carolina soils. Chromium was detected in each soil sample tested at a concentration below the PSRG for chromium 111 but above the PSRG for chromium VI. Chromium III is commonly naturally occurring while the presence of chromium VI is typically associated with industrial activities (metal fabrication/cutting, plating, etc.). The subject site has no history of industrial use and therefore the chromium detected in the soil on the site is likely chromium III. Other RCRA metals were detected at concentrations above laboratory method detection limits but below the PSRGs. Included in Table 3.1 are the results from hand auger soil samples collected in November 2017, which contained Total Petroleum Hydrocarbons DRO and GRO in concentrations above Action Levels. Petroleum compounds (VOCs and SVOCs) were not identified in soil samples collected from SB-1, SB-2 or SB-3. These borings were located approximately 5 to 10 feet further from the source area hand auger samples previously collected. These test results indicate the impacted soils are confined to the immediate proximity of the former AST location. The sample locations in proximity to the former AST location are provided in Drawing 2.2. Mid Atlantic Engineering & Environmental Solubons Phase 11 Environmental Site Assessment Report April 25, 2019 Cary Overture Page 5 3612 & 3624 Davis Drive Cary/Morrisville, North Carolina 3.2 Groundwater Analytical Data No SVOCs were detected in groundwater sampled from TWM-1. Chloroform, the only VOC detected above laboratory method detection limits, was detected in groundwater sampled from TMW-1 at a concentration of 1.2 ug/L, below its NCGQS of 70 ug/L. Three metals were detected in the sample collected from TMW-1. These metals included barium (0.38 ug/L), chromium (0.079 ug/L), and lead (0.015 ug/L). The detected concentrations were all below the NCGQS of 700 ug/L, 10 ug/L and 15 ug/L, respectively. 4.0 CONCLUSIONS AND RECOMMENDATIONS The objective of this assessment was to address the data gaps defined by the Brownfield Program. In November 2017 Mid -Atlantic conducted an assessment of soil in vicinity of a former AST. The results of this November 2017 assessment confirmed that a release form the AST had occurred. The soil samples collected during the April 2019 assessment described herein did not identify the presence petroleum compounds in soil. The original soil samples were collected in closer proximity to the former AST than samples SB-1, SB- 2 and SB-3 (as shown on Drawing 2.2). This suggests the radius of impact is within 10 feet of the former AST. Several soil samples exhibited chromium and arsenic above the chromium VI and arsenic PSRGs. The site does not have a history of industrial use, therefore it is Mid -Atlantic's opinion that the chromium detected in the samples is naturally occurring chromium III. According to the laboratory analysis, the arsenic concentrations detected in the soil samples collected from the subject site fall within levels found naturally in North Carolina soils. The background sample also exhibits the concentrations of arsenic and chromium, which supports that these compounds are naturally occurring and not likely a result of a contaminant release. Based on review of the data collected during this and the November 2017 assessment, Mid -Atlantic concludes: A petroleum release has occurred at the subject site. The extent of soil contamination is limited to the immediate vicinity of the former AST. The release has not impacted groundwater. There is no evidence of environmental impact associated with the cell tower or the two household debris piles located on the subject site. Mid -Atlantic recommends submittal of this report to the NCDEQ Brownfields Program for review and comment.
