The subject Site totals approximately 8.0 acres on two parcels of land located in a mixed light industrial and commercial area of Durham. The Prospective Developer (PD) sold 3.7 acres of the Brownfields Site (i.e., the western parcel) to Crowne at 501, Limited Partnership (hereinafter referred to as the Witherspoon Nursery West property), and the PD retained the eastern 4.3 acres of the Brownfields Site (hereinafter referred to as the Witherspoon Nursery East Property). Future redevelopment of the Site includes residential apartments, commercial, retail, office, and open spaces. A Site location map is provided as Figure 1, and a Site map is included as Figure 2. From the mid- 1970s until the mid-2010s, Witherspoon Rose Culture Inc. conducted plant nursery operations at the Site. These operations included selling gardening supplies, cultivation of plants, and storage of agricultural products that contained pesticides and herbicides. The Witherspoon Nursery East property (3330 Watkins Road; Durham County Parcel Identification No. [PIN] 080021836190) is improved with multiple structures previously used for administration and storage related to historical plant nursery operations. A residential -type structure was constructed in the mid- 1950s in the northeastern portion of the Site and used for administrative purposes. Other Site structures were constructed in various stages from the 1970s through 1980s and are predominantly situated in the central and southeastern portions of the Witherspoon Nursery East property. In addition, an approximately 8,000 square foot (sq ft) irrigation pond is near the eastern property boundary.

(ATC) and Terracon Consultants, Inc. (Terracon) to assess areas of potential environmental concerns related to plant nursery operations. Areas of potential environmental concern included septic systems and associated drain fields, an irrigation pond, three aboveground storage tanks (ASTs) previously utilized for diesel fuel and heating oil, and the historic usage of pesticides and herbicides on the Site. A brief summary of the historical investigations is provided below. 2.1 ATC 2015 Assessment Activities In November 2015, ATC completed soil, groundwater, and sump assessment at the subject Site. The assessment activities were documented in a December 11, 2015 Limited Phase H Environmental Site Assessment report. The sampling was conducted to investigate areas identified during a previous ATC Phase I Environmental Site Assessment (ESA). As part of the field activities, eight (8) borings were advanced via hollow stem auger in various locations throughout the subject Site. The borings were advanced to depths ranging from 7.5 to 25 ft below ground surface (bgs) and soils were collected from a hand auger or standard penetration test (SPT) sampler and later screened with a photoionization detector (PID). The PID screening results did not indicate the presence of volatile organic compounds (VOCs). In addition to the soil assessment, water samples were collected from two water supply wells located in the northeastern and northwestern portions of the Site, two sumps located in the central and south-central portions of the Site, and two temporary monitoring wells in the south-central and southeastern portions of the Site. The temporary monitoring wells were installed to a depth of 25 ft bgs and groundwater was only encountered in one of the temporary wells (B-5 located in the south-central portion of the Site) at an approximate depth of 4.5 ft bgs. According to the report, the water supply well, sump, and temporary monitoring well samples were analyzed for organochlorine pesticides and chlorinated herbicides. The laboratory analytical report indicates that the samples were also analyzed for polychlorinated biphenyls (PCBs). The analytical results S:\AAA-MasterProjects\Crowne Partners Inc - CRP\CRP.001 Crowne at 501 LP Durham BFs\Report\Final to Client\Brownfields Assessment Report hart : h i c k m a n Witherspoon Nursery (BPN 22004-18-032)_20190221.docx SMARTER ENVIRONMENTAL SOLUTIONS did not indicate detections of pesticides, herbicides, or PCBs in the water samples above laboratory reporting limits. 2.2 Terracon 2017 Assessment Activities In September 2017, Terracon completed soil assessment at the Witherspoon Nursery West property. The assessment activities were documented in an October 11, 2017 Limited Site Investigation report and were conducted to investigate areas of potential environmental concern identified during a previous Terracon Phase I ESA. As part of the field activities, composite soil sampling was targeted to seven areas based on historical plant nursery operations. In addition to the composite soil sampling, grab soil sampling was also conducted to investigate potential impacts related to a heating oil AST in the northwestern portion of the Site and a former septic drain field in the southwestern portion of the Site. The composite samples were collected from the ground surface to depths of approximately 6 ft bgs and submitted for laboratory analysis of organochlorine and organophosphorus pesticides, chlorinated herbicides, and the metals arsenic, copper, and lead. The grab samples were collected from depths of approximately 1 to 4 ft bgs and submitted for laboratory analysis of gasoline -range and diesel - range total petroleum hydrocarbons (TPH-GRO and TPH-DRO). The laboratory analytical results indicated arsenic was detected at concentrations ranging from 0.79 to 26 milligrams per kilogram (mg/kg) in the composite and grab samples analyzed. These concentrations exceed the North Carolina Department of Environmental Quality (DEQ) Residential, Industrial/Commercial, and/or Protection of Groundwater Preliminary Soil Remediation Goals (PSRGs). Arsenic is a naturally occurring inorganic compound and can be found in North Carolina soils at concentrations up to 18 mg/kg, which is similar to the aforementioned levels (see Elements in North American Soils by Dragun and Chekiri, 2005). Composite samples collected from former gardening areas in the north -central and central portions of the Site and former septic drain field in the southwestern portion of the Site indicated low levels of pesticides in soils. Organochlorine pesticides aldrin, gamma-BHC, alpha-BHC, and heptachlor S:\AAA-MasterProjects\Crowne Partners Inc - CRP\CRP.001 Crowne at 501 LP Durham BFs\Report\Final to Client\Brownfields Assessment Report hart I- h i c k m a n Witherspoon Nursery (BPN 22004-18-032)_20190221.docx SMARTER ENVIRONMENTAL SOLUTIONS epoxide were detected above their respective Protection of Groundwater PSRGs but below Residential and Industrial/Commercial PSRGs. Grab sampling conducted in the vicinity of the heating oil AST in the northwestern portion of the Site indicated impacted soils. DRO was detected at a concentration (270 mg/kg) that exceeded the DEQ Action Level of 100 mg/kg. 2.3 ATC 2018 Assessment Activities Based on the results of Terracon's 2017 soil assessment, ATC oversaw removal and excavation activities of two former diesel ASTs (AST-1 and AST-2) on the Witherspoon Nursery East property and one former heating oil AST (AST-3) on the Witherspoon Nursery West property. Removal of the ASTs was conducted in March 2018 and documented in the March 28, 2018 and May 1, 2018 Soil Excavation Activities — Witherspoon Roses Property reports prepared by ATC. During removal activities, approximately 5.95 and 6 tons of petroleum impacted soil were excavated from soils in the vicinity of AST-1 and AST-3, respectively. Confirmatory soil samples were then collected from each excavation area for analysis of VOCs and semi -volatile organic compounds (SVOCs). One additional soil sample was also collected from the AST-3 excavation and analyzed for TPH-GRO and TPH-DRO and Toxicity Characteristic Leaching Procedure (TCLP) metals (for disposal purposes). The results of the soil sampling did not indicate exceedances of Residential Maximum Soil Contaminant Concentrations (MSCCs). The Site received eligibility into the DEQ Brownfields Program (Brownfields Project No. 22004- 18-032) via a Letter of Eligibility dated April 26, 2018. On October 10, 2018, H&H participated in a conference call with DEQ Brownfields Program personnel to discuss proposed redevelopment plans for the Site, potential data gaps, and the scope of Brownfields assessment activities needed to address data gaps for development of an Environmental Management Plan (EMP). As requested by DEQ during this conference call, on November 16, 2018, H&H submitted a Brownfields Assessment Work Plan (Work Plan) proposing to conduct soil, groundwater, and irrigation pond assessment activities to further evaluate Site conditions for potential impacts associated with S:\AAA-MasterProjects\Crowne Partners Inc - CRP\CRP.001 Crowne at 501 LP Durham BFs\Report\Final to Client\Brownfields Assessment Report hart I- h i c k m a n Witherspoon Nursery (BPN 22004-18-032)_20190221.docx SMARTER ENVIRONMENTAL SOLUTIONS environmental concerns identified during previous investigations. The DEQ Brownfields Program approved the proposed Work Plan approval in an email dated December 3, 2018. A summary of Brownfields assessment activities is provided in the following sections. S:\AAA-MasterProjects\Crowne Partners Inc - CRP\CRP.001 Crowne at 501 LP Durham BFs\Report\Final to Client\Brownfields Assessment Report hart : h i c k m a n Witherspoon Nursery (BPN 22004-18-032)_20190221.docx SMARTER ENVIRONMENTAL SOLUTIONS 3.0 Brownfields Assessment Activities In January 2019, H&H conducted Brownfields assessment activities at the Site in accordance with the DEQ Brownfields approved Work Plan. The assessment activities included collection of two (2) soil samples for laboratory analyses from the Witherspoon Nursery West property and two (2) co -located surface water and sediment samples for laboratory analyses from the irrigation pond on the Witherspoon Nursery East property. As further discussed below, groundwater was not encountered during the assessment activities. Brownfields assessment sample locations are depicted on Figure 3. Prior to conducting the field activities, H&H contacted North Carolina 811, the public utility locator, to mark subsurface utilities located on the Site. H&H also contracted with a private utility locator to screen proposed sample locations for subgrade utilities not marked by the public locator. Additionally, soil boring locations were hand cleared to 5 ft bgs to further screen the boring locations for the presence of subsurface utilities. The assessment activities were conducted in general accordance with DEQ Inactive Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup (Guidelines) dated October 2015 and the most recent versions of the U.S. Environmental Protection Agency (EPA) Region IV Science and Ecosystem Support Division (SESD) Field Branches Quality System and Technical Procedures guidance. The results of the soil, groundwater, and irrigation pond assessment activities are provided in Sections 4.0 through 6.0, respectively, and summary and conclusions are provided in Section 7.0.

(IET) to collect soil samples for laboratory analysis in areas of two former septic drain fields on the Witherspoon Nursery West property. Specifically, the borings were advanced in the former septic drain field in the southwestern portion of the Site (SB-1) and the former septic drain field south of the administrative building (SB-2) in the west -central portion of the Site. Soil boring locations (denoted by SB nomenclature) are shown on Figure 3. 4.1 Soil Sampling Methodology H&H advanced two (2) soil borings and collected two (2) soil samples for laboratory analysis to further evaluate the potential for impact in the former septic drain fields. As part of soil assessment activities, IET utilized a track -mounted direct push technology (DPT) drill rig to advance soil borings to depths ranging from approximately 5 to 12 ft bgs. Continuous soil samples were collected from the borings using a decontaminated stainless -steel hand auger or acetate lined macrocore sleeves. The soil samples were logged for lithologic description and screened using visual and olfactory methods for obvious evidence of staining, unusual odors, and for the presence of volatile organic vapors using a calibrated PID. Based upon results of field observations and field screening, one soil sample was collected for laboratory analysis from each soil boring from depths below the former septic drain fields (SB-1 at 4-5 ft bgs and SB-2 at 6-8 ft bgs). Boring logs with lithologic descriptions and field screening results are provided in Appendix A. Soil samples selected for laboratory analysis were placed 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 samples were delivered to Pace Analytical, a North Carolina certified laboratory, under standard chain of custody protocols for analysis of VOCs by EPA Method 8260 and SVOCs by EPA Method 8270. In addition, soil sample SB-2 was submitted for analysis of Resource Conservation and Recovery Act (RCRA) metals plus hexavalent chromium by EPA Methods 6020/7471/7199. For quality assurance/quality control purposes, a duplicate soil sample was collected from the SB-2 soil boring and submitted to Pace S:\AAA-MasterProjects\Crowne Partners Inc - CRP\CRP.001 Crowne at 501 LP Durham BFs\Report\Final to Client\Brownfields Assessment Report hart I- h i c k m a n Witherspoon Nursery (BPN 22004-18-032)_20190221.docx SMARTER ENVIRONMENTAL SOLUTIONS Analytical for the same analysis as the SB-2 parent soil sample. Estimated values (J-flag reporting) were requested of the laboratory. Following sampling activities, the soil sample borings were properly abandoned and the surfaces were repaired similar to pre -drilling conditions. Additionally, the soil sample locations were estimated using a hand-held global positioning system (GPS) unit. 4.2 Soil Assessment Results A tabular summary of soil sample analytical results is presented in Table 1, and the laboratory analytical report is provided in Appendix B. The laboratory analytical results were compared to the DEQ IHSB Residential and Industrial/Commercial PSRGs dated February 2018. In addition to the PSRGs, metals results were compared to published background ranges for North Carolina soils published in Elements in North American Soils authored by Dragun and Chekiri (2005). Laboratory analytical results did not indicate the presence of VOCs or SVOCs in either soil sample at concentrations above laboratory method detection limits. As expected, naturally occurring levels of several metals were detected at concentrations above the laboratory method detection limits in each soil sample. Arsenic was detected at a concentration of 1.0 milligrams per kilogram (mg/kg) in SB-2, which exceeds the Residential PSRG of 0.68 mg/kg. Arsenic was also detected in the duplicate sample collected from SB-2 (DUP-SB) at a concentration of 3.02 mg/kg, which exceeds the Industrial/Commercial PSRG of 3.0 mg/kg. The detections of arsenic are consistent with published background ranges for North Carolina soils. No other metals were detected at concentrations exceeding Residential PSRGs. 4.3 Cumulative Risk Calculations The DEQ IHSB PSRGs are conservative and based on a lifetime incremental cancer risk (LICR) for potential carcinogenic risks of 1 x 10-6 and a non -carcinogenic hazard quotient (HQ) of 0.2 for potential non -carcinogenic risks. When calculating Site -specific risks, the DEQ acceptable threshold for potential carcinogenic risks is I x 10-4, and the acceptable level for non -carcinogenic S:\AAA-MasterProjects\Crowne Partners Inc - CRP\CRP.001 Crowne at 501 LP Durham BFs\Report\Final to Client\Brownfields Assessment Report hart I- h i c k m a n Witherspoon Nursery (BPN 22004-18-032)_20190221.docx SMARTER ENVIRONMENTAL SOLUTIONS risks is a hazard index less than 1. Although the arsenic concentrations detected in SB-2 are consistent with naturally occurring levels, to evaluate the potential exposure risk associated with the detected soil concentrations, H&H used the DEQ soil risk calculator using the analytical data for the SB-2 parent and duplicate soil samples. Consistent with planned redevelopment and proposed use at the Site, H&H completed a risk calculator for the sample with higher concentrations (SB-2, duplicate) using the residential, non-residential worker, and construction worker scenarios to evaluate both current risk and potential future need for land use controls. Results of the risk calculator are summarized below and included in Appendix C. Non -Residential Sample Resident Construction Worker Worker Sample ID Depth Carcinogenic Hazard Carcinogenic Hazard Carcinogenic Hazard (ft bgs) Risk Index Risk Index Risk Index SB-2 Fuplicate) 6-8 4.5 x 10"6 0.10 1.0 x 10-6 0.0074 1.7 x 10"7 0.084 As shown in the table above, calculated cumulative risks do not exceed acceptable levels (carcinogenic risk <1 x 10"4 and HI <1) for a future resident, non-residential worker, or a construction worker. 10 ■ S:\AAA-MasterProjects\Crowne Partners Inc - CRP\CRP.001 Crowne at 501 LP Durham BFs\Report\Final to Client\Brownfields Assessment Report hart I- h i c k m a n Witherspoon Nursery (BPN 22004-18-032)_20190221.docx SMARTER ENVIRONMENTAL SOLUTIONS 5.0 Groundwater Assessment Activities On January 2, 2019, H&H supervised installation of three temporary monitoring wells. Temporary monitoring well locations (denoted by TMW nomenclature) are shown on Figure 3 and were advanced in the following locations: • downgradient of the sumps in the central and south-central portions of the Witherspoon Nursery East property (TMW-1); • downgradient of the former septic drain field in the southern portion of the Witherspoon Nursery West property and near the former boring B-5 where groundwater was previously reported (TMW-2); and • near the former heating oil AST south of the administrative building in the northwestern portion of the Witherspoon Nursery West property (TMW-4). In accordance with the DEQ Brownfields approved Work Plan, a fourth temporary monitoring well (TMW-3) was to be installed near the former septic drain field south of the administrative building in the west -central portion of the Witherspoon Nursery West property. However, as further described below, this temporary well was not able to be installed to the target depth of 25 ft. The temporary monitoring well borings were advanced using a combination of hollow -stem auger (HSA) and air rotary drilling methods. Each temporary monitoring well was advanced to a depth of 25 ft bgs and was constructed with 2-inch diameter PVC with 15 ft of 0.010 slot well screen. A sand filter pack was installed from below the base of the monitoring well to approximately 2 ft above the top of the well screens. The temporary monitoring wells were completed by placing a hydrated bentonite seal from the top of the sand filter pack to the ground surface. Following installation, the wells were left overnight to allow to equilibrate to static conditions. Temporary monitoring well boring logs and construction details are provided in Appendix A. Up to two borings were advanced in an attempt to install temporary monitoring well TMW-3 (denoted as TMW-3A and TMW-3B on Figure 3) near the former septic drain field south of the 11 ■ S:\AAA-MasterProjects\Crowne Partners Inc - CRP\CRP.001 Crowne at 501 LP Durham BFs\Report\Final to Client\Brownfields Assessment Report hart I- h i c k m a n Witherspoon Nursery (BPN 22004-18-032)_20190221.docx SMARTER ENVIRONMENTAL SOLUTIONS administrative building in the west -central portion of the Witherspoon Nursery West property. During drilling, perched water, possibly from the former septic drain field, was encountered from depths of approximately 2 to 5 ft bgs. The perched water impeded the drill rig's air hammer from advancing the borings to the target depth of 25 ft bgs. In addition, the perched water contributed to both boreholes exhibiting cave-ins. Termination depths for borings TMW-3A and TMW-were approximately 18 and 9 ft bgs, receptively. On January 3, 2019, H&H returned to the Site to check the three temporary monitoring wells for the presence of groundwater. Upon inspection, groundwater was not observed in the three installed temporary monitoring wells; thus, no groundwater samples were collected for laboratory analysis. The temporary monitoring wells were subsequently properly abandoned and the surfaces were repaired similar to pre -drilling conditions. Additionally, each temporary monitoring well boring location was estimated using a GPS unit. Temporary monitoring well abandonment records are provided in Appendix A. 12 ■ S:\AAA-MasterProjects\Crowne Partners Inc - CRP\CRP.001 Crowne at 501 LP Durham BFs\Report\Final to Client\Brownfields Assessment Report hart I- h i c k m a n Witherspoon Nursery (BPN 22004-18-032)_20190221.docx SMARTER ENVIRONMENTAL SOLUTIONS 6.0 Irrigation Pond Assessment Activities On January 3, 2019, H&H collected two (2) co -located surface water and sediment samples from the irrigation pond located on the Witherspoon Nursery East property. The irrigation pond is not a classified water body according to the DEQ Division of Water Resources North Carolina Surface Water Classifications Map. The nearest downgradient classified surface water body to the irrigation pond is New Hope Creek, which has a classification of WS-V; NSW. The surface water and sediment sample (denoted by SW and SED nomenclature, respectively) locations are shown in Figure 3. 6.1 Surface Water and Sediment Sampling Methodology H&H collected two (2) co -located surface water and sediment samples (SW-1/SED-1 and SW- 2/SED-2) from the irrigation pond located on the Witherspoon Nursery East property. Field measurements of turbidity, dissolved oxygen, temperature, specific conductivity, pH, and oxidation-reduction potential were collected for each surface water sample. The sediment samples were collected from the base of the irrigation pond using a decontaminated stainless steel AMS dredge sampler. The surface water and sediment samples were placed 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 samples were delivered to Pace Analytical under standard chain of custody protocols for analysis of VOCs by EPA Method 8260, SVOCs by EPA Method 8270, RCRA metals plus hexavalent chromium by EPA Methods 6020/7471/7196, organochlorine pesticides by EPA Method 8081, organophosphorus pesticides by EPA Method 8141, and herbicides by EPA Method 8151. In addition to total RCRA metals, surface water samples were also submitted for laboratory analysis of dissolved RCRA metals by EPA Methods 6020/7471 and nitrate by EPA Method 300. Estimated values (J-flag reporting) were requested of the laboratory. Upon completion of sampling, the co -located surface water and sediment sample locations were estimated using a hand-held GPS unit. 13 ■ S:\AAA-MasterProjects\Crowne Partners Inc - CRP\CRP.001 Crowne at 501 LP Durham BFs\Report\Final to Client\Brownfields Assessment Report hart I- h i c k m a n Witherspoon Nursery (BPN 22004-18-032)_20190221.docx SMARTER ENVIRONMENTAL SOLUTIONS 6.2 Surface Water Sampling Analytical Results A tabular summary of surface water sample analytical results is presented in Table 2, and the laboratory analytical report is provided in Appendix B. Surface water data were compared to the DEQ 15A NCAC 02B Surface Water Quality Standards (2B Standards). The 2B Standards for cadmium, trivalent chromium, lead, and silver are hardness -dependent. Therefore, H&H entered the 50% median hardness value of New Hope Creek of 43 milligrams per liter (mg/L) as CaCO3 in the DEQ 15A NCAC 02B Water Quality Standards for Surface Waters Calculator (Calculator) to calculate acute and chronic (where applicable) 2B Standards for cadmium, trivalent chromium, lead, and silver which are used for comparison in Table 2. The Calculator and DEQ Hardness Statistics by 8-Digit HUC, North Carolina, 1969-2013 are presented in Appendix D. Laboratory analytical results did not indicate the presence of VOCs, organochlorine pesticides, organophosphorus pesticides, herbicides, or nitrate at concentrations above the laboratory method detection limit in either of the surface water samples collected. Laboratory analytical results indicate that low levels of phenol were detected in SW-1 (0.508 J micrograms per liter [µg/L)]) and SW-2 (2.76 J µg/L) surface water samples at concentrations above the laboratory method detection limit, but below the 2B Standard of 300 µg/L. No other SVOCs were detected above the laboratory method detection limits. Laboratory analytical results indicate that low levels of total trivalent chromium and total and dissolved arsenic and barium were detected at concentrations above laboratory method detection limits, but below 2B Standards in each surface water sample. No metals were detected at concentrations exceeding 2B Standards in the surface water samples, except total lead. Low levels of total lead were detected in SW-1 at estimated values (1.72 J µg/L) and SW-2 (1.21 J µg/L) at concentrations exceeding the calculated chronic 2B Standard 0.99 µg/L. However, concentrations of dissolved lead were below the chronic 2B Standard in both surface water samples. Based on these results and trace levels of total lead detected, H&H attributes the lead detections to be naturally occurring lead in suspended sediment in the pond water. 14 ■ S:\AAA-MasterProjects\Crowne Partners Inc - CRP\CRP.001 Crowne at 501 LP Durham BFs\Report\Final to Client\Brownfields Assessment Report hart I- h i c k m a n Witherspoon Nursery (BPN 22004-18-032)_20190221.docx SMARTER ENVIRONMENTAL SOLUTIONS 6.3 Sediment Sampling Analytical Results A tabular summary of sediment sample analytical results is presented in Table 3 and the laboratory analytical report is provided in Appendix B. The laboratory analytical results were compared to the DEQ IHSB Residential and Industrial/Commercial PSRGs dated February 2018. In addition to the PSRGs, metals results were compared to published background ranges for North Carolina soils published in Elements in North American Soils authored by Dragun and Chekiri (2005). Laboratory analytical results indicate that low levels of acetone (up to 0.0557 mg/kg), ethylbenzene (up to 0.000848 J mg/kg), 2-butanone (up to 0.0186 J mg/kg), and toluene (up to 0. 00 166 J mg/kg) were detected at concentrations above the laboratory method detection limit, but below their respective Residential and Industrial PSRGs. Acetone was also detected in the laboratory blank and is attributed to laboratory introduced contamination. The other three VOC detections were at trace and estimated (J-flagged) concentrations. Laboratory analytical results did not indicate the presence of SVOCs, organophosphorus pesticides or herbicides at concentrations above the laboratory method detection limit in either of the sediment samples collected. A low level of organochlorine pesticide 4,4-DDE was detected in sediment sample SED-2 at an estimated concentration (0.00498 J mg/kg) above the laboratory detection limit, but well below the Residential PSRG of 2.0 mg/kg. As expected, naturally occurring levels of several metals were detected at concentrations above the laboratory method detection limits in each sediment sample. Arsenic was detected in sediment samples SED-1 (4.39 mg/kg) and SED-2 (3.6 mg/kg) at concentrations that exceed the Residential PSRG of 0.68 mg/kg and Industrial/Commercial PSRG of 3.0 mg/kg. The detections of arsenic are consistent with published background ranges for North Carolina soils. No other metals were detected at concentrations exceeding Residential PSRGs. 15 ■ S:\AAA-MasterProjects\Crowne Partners Inc - CRP\CRP.001 Crowne at 501 LP Durham BFs\Report\Final to Client\Brownfields Assessment Report hart I- h i c k m a n Witherspoon Nursery (BPN 22004-18-032)_20190221.docx SMARTER ENVIRONMENTAL SOLUTIONS 6.4 Cumulative Risk Calculations Although the arsenic concentrations detected in SED-1 and SED-2 are consistent with naturally occurring levels, to evaluate the potential exposure risk associated with the detected sediment concentrations, H&H used the DEQ soil risk calculator using the analytical data for the SED-1 and SED-2 sediment samples. Consistent with planned redevelopment and proposed use at the Site, H&H completed a risk calculator for the sample with higher concentrations (SED-1) using the residential, non-residential worker, and construction worker scenarios to evaluate both current risk and potential future need for land use controls. Results of the risk calculator are summarized below and included in Appendix C. Non -Residential Resident Construction Worker Sample ID Worker Carcinogenic Hazard Carcinogenic Hazard Carcinogenic Hazard Risk Index Risk Index Risk Index SED-1 6.5 x 10-6 0.14 1.5 x 10-6 0.01 2.4 x 10-' 0.11 As shown in the table above, calculated cumulative risks do not exceed acceptable levels (carcinogenic risk <1 x 10-4 and HI <1) for a future resident, non-residential worker, or a construction worker. 16 ■ S:\AAA-MasterProjects\Crowne Partners Inc - CRP\CRP.001 Crowne at 501 LP Durham BFs\Report\Final to Client\Brownfields Assessment Report hart I- h i c k m a n Witherspoon Nursery (BPN 22004-18-032)_20190221.docx SMARTER ENVIRONMENTAL SOLUTIONS 7.0 Summary and Conclusions H&H has completed Brownfields assessment activities at the Witherspoon Nursery Brownfields property located in Durham, North Carolina. The assessment activities were conducted in accordance with the DEQ Brownfields approved Work Plan dated November 16, 2018. Brownfields assessment activities included soil, surface water, and sediment sampling to evaluate for potential impacts and assist in management of Site media during proposed redevelopment activities. A brief summary of the assessment activities is provided below. • Arsenic (up to 3.02 mg/kg) was detected at a concentration above the Industrial/Commercial PSRG of 3.0 mg/kg in the SB-1/DUP-SB soil sample collected in the west -central portion of the Site. The arsenic is attributed to naturally occurring arsenic in the soil. Calculated cumulative risks for soil samples collected at the Site do not exceed acceptable levels for a construction worker, future resident, or a non-residential worker. • No compounds were detected above the DEQ 2B Standards in the surface water samples, except total lead. Total lead (up to 1.72 J µg/L) was detected at estimated concentrations exceeding the chronic 2B Standard of 0.99 µg/L in irrigation pond surface water samples SW-1 and SW-2. However, concentrations of dissolved lead were below the chronic 2B Standard in both surface water samples. Based on these results and trace levels of total lead detected, H&H attributes the lead detections to be naturally occurring lead in suspended sediment in the pond water. • Arsenic (up to 4.39 mg/kg) was detected at concentrations above the Industrial/Commercial PSRG of 3.0 mg/kg in irrigation pond sediment samples SED-1 and SED-2. The arsenic is attributed to naturally occurring arsenic in the soil and sediment. Calculated cumulative risks for sediment samples collected at the Site do not exceed acceptable levels for a construction worker, future resident, or a non-residential worker. • Assessment activities using three temporary wells indicate that groundwater is not present at depths of up to 25 ft bgs. 17 ■ S:\AAA-MasterProjects\Crowne Partners Inc - CRP\CRP.001 Crowne at 501 LP Durham BFs\Report\Final to Client\Brownfields Assessment Report hart : h i c k m a n Witherspoon Nursery (BPN 22004-18-032)_20190221.docx SMARTER ENVIRONMENTAL SOLUTIONS In summary, low level concentrations of naturally occurring arsenic were identified in soil and sediment at the Site. Based on these results, additional assessment does not appear warranted and soil disturbed during future redevelopment activities can be managed in accordance with a Brownfields Environmental Management Plan (EMP). 18 ■ S:\AAA-MasterProjects\Crowne Partners Inc - CRP\CRP.001 Crowne at 501 LP Durham BFs\Report\Final to Client\Brownfields Assessment Report hart : h i c k m a n Witherspoon Nursery (BPN 22004-18-032)_20190221.docx SMARTER ENVIRONMENTAL SOLUTIONS Table 1 Summary of Soil Analytical Data Former Witherspoon Nursery Durham, North Carolina H&H Job Nos.

NATIONWIDE. The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. and Definitions CP IP FTCAbbreviations (dry) Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. MDL Method Detection Limit. FS MDL (dry) Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. [Cn] RDL (dry) Reported Detection Limit. Rec. Recovery. Fr RPD Relative Percent Difference. SDG Sample Delivery Group. Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and PC (S) Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. $ If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the AI Dilution standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. FC These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal Limits for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non -spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. This column provides a letter and/or number designation that corresponds to additional information concerning the result Qualifier reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state "ND" (Not Detected) or "BDL" Result (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry) Confidence level of 2 sigma. A brief discussion about the included sample results, including a discussion of any non -conformances to protocol Case Narrative (Cn) observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control This section of the report includes the results of the laboratory quality control analyses required by procedure or Summary (Qc) analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. This is the document created in the field when your samples were initially collected. This is used to verify the time and Sample Chain of date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This Custody (Sc) chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. This section of your report will provide the results of all testing performed on your samples. These results are provided Sample Results (Sr) by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss) This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description E The analyte concentration exceeds the upper limit of the calibration range of the instrument established by the initial calibration (ICAL). J The identification of the analyte is acceptable; the reported value is an estimate. J1 Surrogate recovery limits have been exceeded; values are outside upper control limits. J3 The associated batch QC was outside the established quality control range for precision. J4 The associated batch QC was outside the established quality control range for accuracy. J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low. v The sample concentration is too high to evaluate accurate spike recoveries.

NATIONWIDE. The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. and Definitions CP IP FTCAbbreviations (dry) Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. MDL Method Detection Limit. FS MDL (dry) Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. [Cn] RDL (dry) Reported Detection Limit. Rec. Recovery. Fr RPD Relative Percent Difference. SDG Sample Delivery Group. Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and PC (S) Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. $ If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the AI Dilution standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. FC These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal Limits for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non -spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. This column provides a letter and/or number designation that corresponds to additional information concerning the result Qualifier reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state "ND" (Not Detected) or "BDL" Result (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry) Confidence level of 2 sigma. A brief discussion about the included sample results, including a discussion of any non -conformances to protocol Case Narrative (Cn) observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control This section of the report includes the results of the laboratory quality control analyses required by procedure or Summary (Qc) analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. This is the document created in the field when your samples were initially collected. This is used to verify the time and Sample Chain of date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This Custody (Sc) chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. This section of your report will provide the results of all testing performed on your samples. These results are provided Sample Results (Sr) by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss) This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description B The same analyte is found in the associated blank. E The analyte concentration exceeds the upper limit of the calibration range of the instrument established by the initial calibration (ICAL). J The identification of the analyte is acceptable; the reported value is an estimate. J1 Surrogate recovery limits have been exceeded; values are outside upper control limits. J2 Surrogate recovery limits have been exceeded; values are outside lower control limits. J3 The associated batch QC was outside the established quality control range for precision. J4 The associated batch QC was outside the established quality control range for accuracy. J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low. P RPD between the primary and confirmatory analysis exceeded 40%.
