The Brownfields Property is approximately 3.872 acres in size and was previously part of Parcel ID No. 14901239 which was approximately 8.6 acres in size. Figure 1 is a site topographic map. Figure 2 is a site location map. Mecklenburg County Parcel ID No 14901239 was owned by Scaleybark Partners, LLC prior to December 20, 2019 when the parcel was subdivided and ownership of Parcel No. 14901254 was transferred to CC LoSo Station, LLC. The Brownfields property was historically the site of residences, commercial/warehouse buildings, a drive in theater, and a commercial shopping center until sometime before 2006. At one time the property was used by a company called Affordable Custom Iron, with historical operations that appeared to include a spray paint booth and an incinerator. After 2006 the main shopping center/commercial buildings were no longer present. In 2009, a parking lot was developed, and no buildings remained on the property by 2012. According to the Brownfields application which was submitted to the North Carolina Brownfields Program (NCBP) on September 13, 2019, redevelopment of the subject Brownfields Property is one portion of a cooperative project between prospective developer, the City of Charlotte, and other third-party developers to return the Brownfields Property and other surrounding parcels to productive use. Redevelopment of the Brownfields Property will include construction of a parking garage that, by agreement with the City, will include free public parking serving passengers using the nearby light rail station. Redevelopment activities are currently occurring at the Brownfields property. An asphalt parking lot has been removed and grading activities were occurring at the time this report was prepared. The walls for the lower level of a subgrade parking deck were under construction at the time this report was prepared. ECS previously performed a Phase I Environmental Site Assessment (Phase I ESA) for this site in May 2019 (ECS Project No. 49-9324). The finding of the Phase I ESA are summarized I a report dated May 22, 2019. In the Phase I ESA Report, ECS identified the following recognized environmental condition (REC) described below: City of Charlotte- Scaleybark Site, 3610 South Boulevard and Clanton Road – Located at the subject property. ECS reviewed information from the online North Carolina Department of Environmental Quality (NCDEQ) Laserfiche database for this incident (Facility ID NONCD0002805). According to a Site Closure Request Report completed by S&ME and dated September 6, 2007, there were spill locations identified at abandoned facilities. The report indicated that there was a motor oil spillage from parked vehicles and pails of waste oil, as well as suspected spillage and over-spray from an ornamental iron spray paint booth. According to the report, this incident occurred in two locations which are described as Detail A and Detail B below. ECS notes these areas have been redeveloped since 2007. The report noted that prior to redevelopment, the City undertook a voluntary cleanup of known areas of soil contamination. The remediation consisted of the removal and off-site disposal of contaminated soils from areas of the property identified during a Phase II ESA. Several excavations were performed at Detail A and B (further discussed on the following pages). Report of Environmental Assessment Affordable Custom Iron ECS Project No. 49:10479-A April 29, 2020 2 Detail A Location: This location consists of a larger tract of land that included a portion of the subject property, as well as the north adjoining property. The building, which was formerly located on the north adjoining property, was formerly occupied by Consolidated Steel Building (101 Clanton Road), a structural steel fabricator and constructor. The report noted that the source of the soil contamination was spills/leaks of motor oil from parked vehicles and small storage containers. This location had impacts of Oil and Grease (O&G) and Total Petroleum Hydrocarbons-Diesel Range Organics (TPH-DRO) above the NCDEQ Action Levels of 250 milligrams per kilogram (mg/Kg) for O&G and 40 mg/Kg for TPH-DRO, respectively. Soil excavations occurred in June and July of 2007. The impacted soils were transported to an off-site treatment facility. Approximately 325 tons of impacted soils were removed. Post-remediation samples collected at the bottom of the excavations indicated that the contaminant levels of soil remaining in place did not exceed the NCDEQ action level for O&G or TPH-DRO. S&ME recommended that no further soil remediation appeared to be necessary at the Consolidated Steel site. On September 24, 2007, the NCDEQ issued a No Further Action (NFA) letter indicating they had reviewed the September 2007 Site Closure Report and that the soil contamination does not equal or exceed the TPH action level for semi-volatile organics or O&G for this incident (Incident 91007). Detail B Location: This location was formerly located at the subject property and was identified as 3610 South Boulevard. The former onsite building was occupied with Affordable Custom Iron, which was an ornamental iron fabricator. Two locations at this former facility were found to have contaminants exceeding remediation goals. The report noted that the cleanup criteria used were the lesser of the NCDEQ Inactive Hazardous Sites Branch (IHSB) Health-Based Remediation Goals (RG) or the NCDEQ Soil-to-Groundwater Maximum Soil Contaminant Concentrations (MSCCs). The contaminants included benzene, carbon tetrachloride, and arsenic at location TP-1 and benzo(a)pyrene and dibenzo(a,h)anthracene at location SS-3. Soil excavations reportedly occurred in June and July of 2007. The impacted soils were transported to an off-site treatment facility. Approximately 76 tons of impacted soils were removed. Post-remediation samples collected at the bottom of the excavations indicated that the organic contaminant concentrations of the soil remaining in place did not exceed their respective NCDEQ IHSB Health-Based RG or the MSCCs. In addition, the report noted that arsenic concentrations did not exceed the NCDEQ IHSB Health-Based RG and the toxicity characteristic leachate procedure leachable arsenic level (TCLP Arsenic) did not exceed the NCDEQ IHSB soil limits considered protective of groundwater. S&ME recommended that no further soil remediation appeared to be necessary at the Affordable Custom Iron site. On September 24, 2007, the NCDEQ indicated in an NFA letter that they had reviewed the September 2007 Site Closure Report and that the soil contamination does not exceed the soil-to-groundwater MSCCs. The NCDEQ noted that the NFA only applies to this incident (Incident 91008) and the non- petroleum contamination found in form of carbon tetrachloride and arsenic was being referred to the IHSB. Report of Environmental Assessment Affordable Custom Iron ECS Project No. 49:10479-A April 29, 2020 3 Ms. Erika Frey, REM contacted Mr. David Ramey with the NCDEQ-Division of Waste Management on May 15, 2019. According to Mr. Ramey, he was not aware of more recent reports than the records dated 2007. Mr. Ramey indicated that he spoke with Mr. David Wolfe with the City of Charlotte Engineering and Property Management in 2012/2013 and indicated that Mr. Wolfe said that the City of Charlotte did not intend to perform additional assessment for Charlotte-Scaleybark Site (NONCD0002805). Mr. Ramey recommended contacting the NCDEQ Underground storage tank (UST) Section for UST records associated with this site. Ms. Frey contacted Mr. Dan Bowser with the NCDEQ on May 16, 2019 for information pertaining to USTs. Mr. Bowser indicated that Incidents 91007 and 91008 occurred at the property. ECS considers the leaking aboveground storage tank (LAST) incidents (incident numbers 91007 and 91008) to be historical recognized environmental conditions (HRECs) of the subject property. Although the LAST Incidents (incident numbers 91007 and 91008) have received NFA status, the NFA associated with Incident 91008 (Affordable Custom Iron) noted that the non-petroleum contamination (carbon tetrachloride and arsenic) was being referred to the IHSB. Based on interviews and record review, ECS did not identify regulatory closure documents for the non-petroleum contamination. Based on this information, ECS considers the SHWS listing to be a REC of the subject property. Draper Aden Associates performed passive soil gas monitoring at the Brownfields Property in August and September 2019 which is summarized in a report titled Soil Gas Assessment Report dated October 10, 2019. During this assessment, Draper Aden Associates emplaced passive soil gas samples at 37 locations across the Brownfields Property on August 21 and 22, 2019 and retrieved these samples on September 6, 2019. The samples were analyzed for volatile organic compounds (VOCs). One exceedance above IHSB vapor intrusion screening levels (VISLs) for residential exposure scenarios was noted. The exceedance was for naphthalene which was detected in a sample near the location of the former Affordable Custom Iron facility. Draper Aden Associates input a maximum detection concentration scenario of the VOCs into NCDEQ risk calculator and noted that the calculated risk did not exceed acceptable risk levels. On September 13, 2019, CC LoSo Station, LLC submitted a Brownfields Property Application to the NCDEQ. On October 17, 2019 NCDEQ issued a Letter of Eligibility (LOE) to CC LoSo Station, LLC indicating that the subject property was eligible for the NCBP. The Brownfields Identification Number assigned to this site is 23056-19-060. On July 17, 2019, representatives from ECS, NCBP and TAC Tremont, LLC met on site to discuss data gaps and possible additional assessment activities required before the Brownfields Agreement is finalized. On December 19, 2019, the NCBP forwarded a Request for Additional Assessment (RAA) to CC LoSo Station, LLC. After the RAA was issued, ECS and the NCBP had discussions regarding the necessity of the number of soil gas sampling points indicated in the RAA. On January 8, 2020, the NCBP indicated by telephone that the number of soil gas sampling points could be reduced from seven to four and that the three sampling points not near the proposed courtyard shown on a figure included with the RAA need not be sampled. ECS submitted a work plan to the NCBP in response to its RAA. The January 20, 2020 work plan was prepared to address groundwater, soil, and soil gas assessment. The approved work plan was implemented. This report summarizes the findings from the assessment activities which were performed as outlined in the approved work plan. Report of Environmental Assessment Affordable Custom Iron ECS Project No. 49:10479-A April 29, 2020 4 2.0 SCOPE OF SERVICES The environmental assessment consisted of the collection of soil, groundwater samples, and soil gas samples. Drilling activities were conducted by North Carolina licensed well drillers using two Geoprobe® drill rigs. One Geoprobe® drill rig was equipped with sonic drilling equipment. The other Geoprobe® drill rig was equipped for direct push technology (DPT) drilling. The subcontractor used for this project was Geologic Exploration Company (GEX) of Statesville, North Carolina. Drilling, soil sampling, and soil gas sampling activities were conducted on March 20, 2020. Groundwater sampling was performed on March 24, 2020 and March 26, 2020. A photographic log documenting the field activities is provided in Appendix B. 2.1 Public Utility Locate Prior to implementing the field activities, ECS contacted North Carolina public utility locate service (811) 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 2.2 Monitoring Well Permit A Mecklenburg County Subsurface Investigation Permit (SIP) was procured. The Mecklenburg County SIP is included as Appendix C. 2.3 Soil Boring Activities On March 20, 2020, ten (10) soil borings were advanced at the site. The soil boring designations were SB- 1 through SB-10. The soil boring locations are depicted on Figure 3. Soil borings SB-1, SB-2, SB-3, SB-5, SB-8, SB-9, and SB-10 were advanced by DPT by hydraulically driving a five-foot long, 1.5-inch diameter soil sampling probe into the soil to a depth of up to 10 feet below the ground surface (bgs). Prior to advancing each boring, the down-hole equipment was decontaminated utilizing a pressure washer and municipal water. The down-hole equipment was decontaminated to prevent cross-contamination between boring locations. Soil borings SB-6, SB-7, and SB-10 were advanced by sonic drilling techniques using 6-inch diameter bit. Sonic drilling works by sending high frequency vibration from the drill head through the drill string to the drill bit. The driller can adjust the resonance frequency to suit the type of earth materials being drilled. This resonance causes fluidization of the earth materials at the drill surface. As the drill string advanced, soil was collected within the rods which were lined with a flexible plastic sleeve. A minimal amount of water was used during the drilling method. Soil boring SB-9 was originally drilled by DPT but was overdrilled using sonic drilling techniques. Prior to advancing each boring, the down-hole equipment was decontaminated utilizing a pressure washer and municipal water. The down-hole equipment was decontaminated to prevent cross-contamination between boring locations. Soil boring SB-4 were advanced using a hand auger. The hand auger was decontaminated utilizing scrub brush, soap, and municipal water and was then rinsed with municipal water. The hand auger was decontaminated to prevent cross-contamination between boring locations. Report of Environmental Assessment Affordable Custom Iron ECS Project No. 49:10479-A April 29, 2020 5 Soils were collected continuously from each of the soil boring locations. ECS visually classified the soil collected from each boring and screened the soils for relative levels of volatile organic vapors using a photoionization detector (PID). Boring logs, which include descriptions of the soils encountered and field screening results, were prepared for each boring and are included in Appendix D. Soil cuttings were spread out on site into a thin layer. On March 23, 2020, Tidemark Land Services, Inc. surveyed the horizontal locations and ground surface elevations of the soil boings. Appendix E contains a table which summarizes this survey data. 2.4 Soil Sample Collection On March 20, 2020, soil samples were collected by a sampler wearing a new pair of disposable nitrile gloves. Soil samples were collected from an interval between 3 and 5 feet bgs from soil borings SB-1 through SB-8. A duplicate of soil sample SB-3 was also collected. A soil sample was collected at a depth of 4 feet bgs from soil boring SB-9 and a soil sample was collected at a depth of 2 feet bgs from soil boring SB-10. Soil samples SB-9 and SB-10 were selected based on the depth that displayed the greatest evidence of impact (i.e. odor, staining, and/or elevated PID readings in soil borings). The soil samples were placed directly into laboratory provided containers. The soil sample containers were labeled with ECS project number, sample identification, sample date and time, and requested analytical analysis. The containers were placed into a cooler with ice to maintain the samples at approximately 4° Celsius (C°). The samples were submitted to Pace Analytical Services, LLC (Pace) in Huntersville, North Carolina for analysis of VOCs using EPA Method 8260, semi-volatile organic compounds (SVOCs) using EPA Method 8270, Resource Conservation and Recovery Act (RCRA) metals using EPA Methods 6010 and 7470, and hexavalent chromium using EPA Method 7199. In addition, two trip blank samples were analyzed for VOCs. ECS maintained chain-of-custody (COC) procedures throughout the sample collection and transportation process. A copy of the COC is included in Appendix F. 2.5 Monitoring Well Installation Activities On March 20, 2020, permanent monitoring wells were constructed in the within soil borings SB-6, SB-7, and SB-9 and were designated as monitoring wells MW-1, MW-2, and MW-3, respectively. The monitoring well locations are depicted on Figure 3. At monitoring well locations MW-1 and MW-2, a 15-foot section of 2-inch diameter well screen was connected to a 2-inch diameter section of well casing. At monitoring well location MW-3, a 4-foot section of 2-inch diameter well screen was connected to a 2-inch diameter section of well casing. Monitoring well MW- 1 was a total of 25 feet deep, monitoring well MW-2 was a total of 20 feet deep, and monitoring well MW-3 was a total of 8 feet deep. Rock was encountered at approximately 8 feet bgs at monitoring well MW-3. The material of construction of the well screen and casing was schedule 40, polyvinyl chloride (PVC) pipe. The well screen contained 0.010-inch slots which were machine cut. The casing and screen were placed into the boring through the hollow stem augers. Report of Environmental Assessment Affordable Custom Iron ECS Project No. 49:10479-A April 29, 2020 6 After the well screen and casing was set, fine silica sand was place around and approximately 2 feet above the top of the well screen at each monitoring well location. The augers were extracted as the sand was place to mitigate possible sand locking and inadvertent extraction of wells screen and casing. A 3-foot (approximate) bentonite seal was place above the filter sand and the remaining annular space was grouted nearly to grade at each monitoring well location. Each monitoring well was completed flush to grade inside an 8-inch diameter, bolt-down manhole set in a 2-foot by 2-foot concrete pad. Each monitoring well was provided with a locking expansion plug. Following completion of the well construction, the driller developed monitoring wells MW-1 and MW-2 by overpumping with an electric submersible pump. Water was extracted from each well until it appeared relatively free of sediments. Development water was discharged to the surface of the land near each well. Monitoring well MW-3 was dry and was therefore not developed. On March 23, 2020, Tidemark Land Services, Inc. surveyed the horizontal locations and ground surface and top of casing elevations of the monitoring wells. Appendix E contains a table which summarizes this survey data. On April 13, 2020, ECS arranged for a North Carolina licensed well driller to visit the site for the purpose of abandoning the three monitoring well. The wells could not be located and are presumed to have been destroyed by construction activities. 2.6 Groundwater Sample Collection ECS returned to the subject site on March 24, 2020 and March 26, 2020 for the purpose of conducting groundwater monitoring activities. Monitoring well MW-1 was sampled on March 24, 2020 and monitoring well MW-2 was sampled on March 26, 2020. A duplicate sample from monitoring well MW-2 was also collected. Groundwater was not encountered in monitoring well MW-3 and it was not sampled. Prior to collection of groundwater samples, ECS measured the depth to water in each monitoring well using an electronic water level meter (Heron Model Dipper T). ECS opened each monitoring well and allowed each well to equilibrate with atmospheric pressure prior to collecting depth to water measurements. ECS cleaned the water level indicator prior to use at each monitoring well. Measurements were recorded to the nearest one-hundredth of a foot. The depth to water below the top of casing (btoc) was 10.86 feet in monitoring well MW-1 on March 24, 2020 and 6.19 feet in monitoring well MW-2 on March 26, 2020 Measurements of the depth to water for the groundwater sampling collection activities are included in Appendix G. Monitoring wells MW-1 and MW-2 were sampled using low-flow sampling techniques in general conformance with the procedures outlined in the January 20, 2020 work plan. Groundwater was extracted from each monitoring well at low flow rates using an electric submersible variable speed sampling pump (Proactive Environmental Products Stainless Steel 12 volt Monsoon Model with Power Booster II LCD Controller). ECS cleaned the pump prior to use at each monitoring well. A new length of polyethylene tubing was connected to the pump and the pump was lowered to the approximate midpoint between the measured water level and bottom of the screen in each monitoring well. The polyethylene tubing was connected to a flow cell into which the probe of a multi-parameter water quality meter (Hanna model 9829) was inserted. Field water quality measurements were collected as water was extracted from each Report of Environmental Assessment Affordable Custom Iron ECS Project No. 49:10479-A April 29, 2020 7 well and passed though the flow cell. Excess water was discharged to the surface of the land near each monitoring well. Appendix G includes groundwater sampling field parameters data. Groundwater was pumped from each monitoring well using the submersible electric pump directly into laboratory provided containers at each of the sampling locations. An equipment blank sample was collected during the groundwater sampling activities. The groundwater sample containers were labeled with ECS project number, sample identification, sample date and time, and requested analytical analysis. The containers were placed into a cooler with ice to maintain the samples at approximately 4C°. The soil samples were submitted to Pace. The groundwater samples were submitted for analysis of VOCs using EPA Method 8260, SVOCs using EPA Method 8270, and RCRA metals/dissolved RCRA metals using EPA Methods 6010 and 7470. In addition, one trip blank sample was analyzed for VOCs. ECS maintained COC procedures throughout the sample collection and transportation process. A copy of the COC is included in Appendix F. 2.7 Soil Gas Sample Point Installation Activities On March 20, 2020, ECS installed four permanent sub-slab soil gas sample points. The locations of the sample points are shown on Figure 3. Each soil gas sample point was constructed by excavating a 1.5 diameter boring using a DPT drill rig to a depth of 7 feet bgs. A stainless-steel vapor implant was placed in the bottom of each boring. Nylaflow or Teflon® tubing was connected to vapor implant and routed above grade at each sample point. Clean quartz filter sand was placed around and approximately 6 inches above the vapor implant at each sample point. A 1-foot (minimum) bentonite seal was placed above the filter sand and hydrated and the remaining annular space was grouted to near-grade at each sample point. A bolt-down manhole was provided at each sample point and was set within a 1.5-foot by 1.5 foot concrete pad. After allowing at least 30 minutes for the bentonite seal to hydrate, the seal was leak tested using helium gas, a gas shroud, and a helium detector as recommended in NCDEQ-DWM Vapor Intrusion Guidance (Alexander, March 2018). Helium was released into the shroud and the helium concentration inside the shroud was monitored. When the helium concentration was approximately 30 percent, a soil gas sample was collected and measured with a helium detector. If the concentration of measured helium concentration was less than 10 percent of the helium concentration inside the shroud, the seal on the soil gas probe was considered to be tight and not leaking. If the test results are not acceptable, ECS took steps to achieve a better seal and repeat the test until the results are acceptable. 2.8 Soil Gas Sample Collection After leak testing, the sample train was purged of approximately 3 tubing volumes at a rate of 200 milliliters per minute or less using a syringe or other appropriate device. The tubing was then connected to a pre-evacuated and pre-cleaned Summa canister for sampling. ECS utilized 1-liter Summa canisters which were batch certified by laboratory. ECS checked and noted the vacuum on each Summa Canister before initiating the sampling procedure. ECS terminated the sampling procedure at each sampling point while vacuum was still present in the canister. ESC terminated sampling when vacuum decreased below 8 inches of mercury (in-Hg) and before it decreased below 5 in-Hg. ECS noted the vacuum for each canister at the end of the sampling procedure. ECS collected a duplicate soil gas sample at soil gas sampling point Report of Environmental Assessment Affordable Custom Iron ECS Project No. 49:10479-A April 29, 2020 8 SG-1. The duplicate sample was collected through a sampling tee. The duplicate sample was submitted to the laboratory without indicating from which sample point it was collected. ECS prepared soil gas sample logs which are included as Appendix H. The soil gas samples were submitted to H&P Mobile Geochemistry, Inc. (H&P) for analysis of VOCs using EPA Method TO-15. ECS maintained COC procedures throughout the sample collection and transportation process. A copy of the COC is included in Appendix F. 3.0 RESULTS 3.1 Soil Sample Results A summary of the soil analytical results are provided on Table 1. As shown in this table, the analytical results for soil sample results were compared to Preliminary Soil Remediation Goals (PSRGs) established by the North Carolina Inactive Hazardous Sites Branch (IHSB). The PSRGs were last updated by the IHSB in December 2019. For each compound, the IHSB has established three different PSRGs for three different exposure scenarios. These three scenarios are protection of groundwater, residential, and industrial/commercial. Acetone was identified in each soil sample at concentrations above laboratory detection limits; however, the concentration did not exceed its PSRGs. The acetone results for each of the soil samples except soil sample SB-10 were J-flagged by the laboratory meaning the reported value is an estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. Additional targeted VOCs or SVOCs were not detected above laboratory detection limits. Barium, trivalent chromium, and lead were identified at concentrations above laboratory detection limits in each of the soil samples; however, the concentrations did not exceed their respective PSRGs. Arsenic was identified at concentrations above the Residential Health-Based PSRG in soil samples SB-1 (1.3 mg/kg), SB-2 (2.2 mg/kg), SB-4 (1.9 mg/kg), and SB-8 (2.1 mg/kg). Arsenic was identified at concentrations above the Residential and Industrial/Commercial Health-Based PSRGs in soil samples SB- 3 (3.6 mg/kg), SB-5 (5.4 mg/kg), SB-6 (4.6 mg/kg), SB-7 (3.8 mg/kg), SB-10 (4.5 mg/kg), and SB-DUP (3.8 mg/kg). Arsenic was identified at concentrations above the Protection of Groundwater, Residential, and Industrial/Commercial PSRGs in soil sample SB-9 (52.7 mg/kg). Cadmium was identified at concentrations above laboratory detection limits in each of the soil samples except soil sample SB-3 which did not detect a concentration above the laboratory detection limit. The concentration in soil sample SB-9 was identified at a concentration above Protection of Groundwater and Residential Health-Based PSRGs (54.6 mg/kg), but below its Industrial/Commercial Health-Based PSRG. The remaining concentrations were not above the PSRGs. Hexavalent chromium was detected at concentrations above the Residential Health-Based PSRG in soil samples SB-3 (0.374 J mg/kg), SB-7 (0.415 J mg/kg), SB-8 (0.423 J mg/kg), and SB-DUP (0.506 J mg/kg), but below the remaining PSRGs. The hexavalent chromium results for these soil samples were J-flagged by the laboratory. Hexavalent chromium was not detected at concentrations above laboratory detection limits in the remaining soil samples. Report of Environmental Assessment Affordable Custom Iron ECS Project No. 49:10479-A April 29, 2020 9 Mercury was detected at concentrations above laboratory detection limits in soil samples SB-3, SB-5, SB- 6, SB-7, SB-8, SB-9, SB-10, and SB-DUP, but below the PSRGs. Mercury was not detected at concentrations above laboratory detection limits in the remaining soil samples. Selenium was detected at a concentration above the laboratory detection limit in soil sample SB-DUP, but the concentration is not above the PSRGs. Soil sample SB-9 detected selenium at a concentration above its Protection of Groundwater PSRG (49.5 mg/kg), but below the remaining PSRGs. Selenium was not detected at concentrations above laboratory detection limits in the remaining soil samples. Silver was detected at a concentration above laboratory detection limits in soil samples SB-7, SB-10, and SB-DUP, but the concentrations are not above the PSRGs. Silver was not detected at concentrations above laboratory detection limits in the remaining soil samples. The laboratory data sheets are included in Appendix F. 3.2 Groundwater Sample Results A summary of the groundwater analytical results are provided on Table 2. As shown in this table, the analytical results for groundwater sample results were compared to the North Carolina 2L Groundwater Quality Standards (NC2LGWQS) and the vapor intrusion screening levels (VISLs) for residential and non- residential exposure scenarios. VISLs were established by the IHSB. The VISLs were last updated by the IHSB in February 2018. Barium and dissolved barium were detected at concentrations above laboratory detection limits in each of the groundwater samples; however, the concentrations do not exceed its NC2LGWQS. Chromium was detected at concentrations above its NC2LGWQS in each of the groundwater samples (MW-1 21.0 ug/L, MW-2 11.0 ug/L, DUP-1 34.8 ug/L). Dissolved chromium was detected at concentrations above its NC2LGWQS in groundwater samples MW-2 (26.7 ug/L) and DUP-1 (21.8 ug/L). Groundwater sample MW- 1 did not detect a concentration above the laboratory detection limit. Selenium was detected at a concentration above the laboratory detection limit in groundwater sample DUP-1; however, this concentration does not exceed its NC2LGWQS. Groundwater samples MW-1 and MW-2 did not detect concentrations above laboratory detection limits. Dissolved selenium was detected at concentrations above laboratory detection limits in groundwater samples MW-2 and DUP-1; however, these concentrations do not exceed its NC2LGWQS. Groundwater sample MW-1 did not detect a concentration above the laboratory detection limit. The identified selenium results were J-flagged by the laboratory. Since metals are volatile, VISLs are not available for these identified compounds. Acetone was detected at concentrations above laboratory detection limits in groundwater samples MW- 2 and DUP-1; however, these concentrations do not exceed its NC2LGWQS or VISLs. Groundwater sample MW-1 did not detect a concentration above the laboratory detection limit. The identified concentration in groundwater sample MW-2 was J-flagged by the laboratory. Bromodichloromethane was detected at a concentration above the laboratory detection limit in groundwater sample DUP-1; however, the concentration does not exceed its NC2LGWQS or VISLs. The identified concentration in groundwater sample DUP-1 was J-flagged by the laboratory. Groundwater samples MW-1 and MW-2 did not detect Report of Environmental Assessment Affordable Custom Iron ECS Project No. 49:10479-A April 29, 2020 10 concentrations above laboratory detection limits. Additional targeted VOCs or SVOCs were not detected above laboratory detection limits. The laboratory data sheets are included in Appendix F. 3.3 Sub-Slab Soil Gas Sample Results A summary of the soil gas analytical results are provided on Table 3. As shown in this table, the analytical results for soil gas sample results were compared to the NCDEQ-Division of Waste Management (DWM) Residential and Non-Residential Vapor Intrusion Screening Levels (VISLs). VISLs were established by the IHSB. The VISLs were last updated by the IHSB in February 2018. Laboratory results of the soil gas samples identified several compounds at concentrations above laboratory detection limits; however, the concentrations are below the Residential and Non-Residential VISLs. 4.0 DISCUSSION The concentrations of arsenic in soil samples SB-1 through SB-8, SB-10, and SB-DUP (duplicate of soil sample SB-3) ranged from 1.3 mg/kg to 5.4 mg/kg. Shacklette and Boerngen (1984) report that the geometric and arithmetic mean concentrations of arsenic in surficial soil samples collected in the eastern United States were 4.8 and 7.4 mg/kg, respectively. Based upon review of this report and our professional experience, ECS opines that the detected concentrations of arsenic detected in these soil samples are consistent with expected concentrations of naturally occurring arsenic in this region and are not necessarily indicative of a release of hazardous substances. However, the concentration of arsenic of 52.7 mg/kg in soil sample SB-9 is not consistent with expected concentrations of naturally occurring arsenic. Cadmium was identified at a concentration above Protection of Groundwater and Residential Health- Based PSRGs, but below its Industrial/Commercial Health-Based PSRG in soil sample SB-9. Selenium was detected at a concentration above its Protection of Groundwater PSRG, but below the remaining PSRGs in soil sample SB-9. Hexavalent chromium was detected at concentrations above the Residential Health-Based PSRG in soil samples SB-3, SB-7, SB-8, and SB-DUP (duplicate of soil sample SB-3), but below the remaining PSRGs. The hexavalent chromium results for these soil samples were J-flagged by the laboratory. Hexavalent in the environment is almost totally derived from human activities (WHO, 1990). The presence of hexavalent chromium in soil at depth in these soil sample locations may require contingencies for handling soil during the proposed redevelopment of the subject property. Acetone was identified in each soil sample at concentrations above laboratory detection limits; however, the concentration did not exceed its PSRGs. The acetone results for each of the soil samples except soil sample SB-10 were J-flagged by the laboratory. Acetone is a common laboratory contaminant (USEPA, 1991). Additional targeted VOCs or SVOCs were not detected above laboratory detection limits. Based upon these results, VOCs in soil do not appear to be a concern with respect to the proposed redevelopment of the subject property. Report of Environmental Assessment Affordable Custom Iron ECS Project No. 49:10479-A April 29, 2020 11 Chromium was detected in groundwater samples MW-1, MW-2, and DUP-1 (duplicate of MW-2) and dissolved chromium was detected in groundwater samples MW-2 and DUP-1. The concentrations identified were above the NC2LGWQS. With the exception of acetone and bromodichloromethane, no VOCs were detected in groundwater samples during this assessment. The identified compounds were detected at concentrations below their respective NC2LGWQSs and VISLs. In addition, SVOCs were not detected above laboratory detection limits. Based upon these results, VOCs and SVOCs in groundwater do not appear to be a concern with respect to the proposed redevelopment of the subject property. Laboratory results of the soil gas samples identified several compounds at concentrations above laboratory detection limits; however, the concentrations are below the Residential and Non-Residential VISLs. Therefore, it is not expected that vapor mitigation measures and/or additional assessment would be required for the proposed redevelopment of the subject property under the NCBP. 5.0 CONCLUSIONS Based on the results of the field activities and laboratory analysis, ECS concludes the following: • The concentrations of arsenic in soil samples SB-1 through SB-8, SB-10, and SB-DUP (duplicate of soil sample SB-3) were detected at concentrations above Residential and Industrial/Commercial Health-Based PSRGs. The detected concentrations of arsenic associated with soil borings SB-1 through SB-8 and SB-10 are consistent with expected concentrations of naturally occurring arsenic in this region and are not necessarily indicative of a release of hazardous substances. However, the concentration of arsenic of 52.7 mg/kg in soil sample SB-9 is not consistent with expected concentrations of naturally occurring arsenic. In addition, cadmium and selenium were detected at concentrations exceeding their respective PSRGs at the location of soil sample SB-9. • Hexavalent chromium was detected at concentrations above the Residential Health-Based PSRG in soil samples SB-3, SB-7, SB-8, and SB-DUP (duplicate of soil sample SB-3), but below the remaining PSRGs. The presence of hexavalent chromium in soil at depth in these soil sample locations may require contingencies for handling soil during the proposed redevelopment of the subject property. • Acetone, a common laboratory contaminant, was detected in soil at concentration below PSRGs for each of the soil samples. No other VOCs or SVOCs were detected in soil during this assessment. • Chromium was detected in groundwater samples MW-1, MW-2, and DUP-1 (duplicate of MW-2) and dissolved chromium was detected in groundwater samples MW-2 and DUP-1. The concentrations identified were above the NC2LGWQS. • With the exception of acetone and bromodichloromethane, no VOCs were detected in groundwater samples during this assessment. The identified compounds were detected at concentrations below their respective NC2LGWQSs and VISLs. In addition, SVOCs were not detected above laboratory detection limits.
