The Site consists of the following three contiguous parcels of land: • 3210 Cullman Avenue (Parcel #08303106) — a 0.49-acre vacant property owned by Mecklenburg County developed with a stormwater culvert and right of way along the western property boundary; • 3214 Cullman Avenue (Parcel #08303105) —a 0.48-acre property developed with a vacant 10,000-square ft industrial office/warehouse building constructed in 1964 and previously occupied by Beaty's Bindery; and • 300 E. 30h Street (Parcel #08303104) — a 1.88-acre property developed with a 30,940- square ft industrial office/warehouse building constructed in 1953 and previously occupied by Parrish Tire Co. for retreading tires. A Site location map is provided as Figure 1. During Phase I ESA activities conducted on the on the 3214 Cullman Avenue parcel, H&H identified the following Recognized Environmental Conditions (RECs) associated with this parcel, and associated with the 3210 Cullman Avenue and 300 E. 36th Street parcels that were identified as off -site properties in the Phase I ESA: 1 hart '` hckman https://harthick.shmepoint.com/sites/MasterFiles-I/Shared Documents/AAA-Master Projects/Avery Hall Investments (AHI)/AHI-007 Cullman Avenue Brownfields/Addiow Phase Il ESA/Report/Additional Phase II ESA Beaty's Bindery - Final.docx SMANTER ENVIRONMENTAL SOLUTIONS 3210 Cullman Avenue • The former Inx International Ink Company (Inx) facility previously operated on the 3210 Cullman Avenue parcel and on the adjacent parcel to the west (3200 Cullman Avenue). Inx operated on this property from an unknown date prior to 1983 as an ink manufacturer, which included making ink from chromium and lead as well as cleaning the machinery used in the process. In January 2005, lead was detected at concentrations up to 1,200 milligrams per kilogram (mg/kg) and chromium was detected up to 590 mg/kg in building material samples. In addition, lead and chromium were also detected in outdoor soil samples along the southern Site boundary at concentrations up to 920 mg/kg for lead and 250 mg/kg for chromium. Low concentrations of tetrachloroethylene (PCE) and the pesticide dieldrin were also detected in the soil samples. In April 2005, additional soil sampling was conducted at seven different locations south of the former Site buildings. Chromium was detected at concentrations of up to 170 mg/kg and lead was detected at concentrations of up to 620 mg/kg. In July 2005, groundwater samples collected from a monitoring well installed on the south side of the former Inx building indicated the following compounds above the North Carolina Department of Environmental Quality (DEQ) 2L Groundwater Quality Standards (2L Standards): n-propylbenzene (520 micrograms per liter [µg/L] versus 2L Standard of 70 µg/L), 1,2,4-trimethylbenzene (2,700 µg/L versus 2L Standard of 400 µg/L), and 1,3,5- trimethylbenzene (1,200 µg/L versus 2L Standard of 400 µg/L). These compounds are typically associated with petroleum -related sources and may be associated with the use of petroleum -based inks at the facility. There does not appear to have been additional assessment completed at the property to assess former Inx operations since 2005 and the property remains on the DEQ Inactive State Priority List (SPL). However, groundwater assessment activities on the former Inx property have continued as part of the assessment of the off -site chlorinated solvent release reported at the Trex/Detrex properties, which are discussed further below. 2 hart '` hickman https://harthick.shmepoint.com/sites/MasterFiles-I/Shared Documents/AAA-Master Projects/Avery Hall Investments (AHI)/AHI-007 Cullman Avenue Brownfields/Addiow Phase Il ESA/Report/Additional Phase II ESA_Beaty's Bindery - Final.docx SMARTEN ENVIRONMENTAL SOLUTIONS • Trex/Detrex, Inc. historically operated a waste solvent recycling facility at the property located at 3114 Cullman Avenue beginning in 1983. Facility operations included recycling and recovery of chlorinated solvents, solvent sales, and parts cleaning services. Trex/Detrex also occupied the property located at 3124 Cullman Avenue. During a Facility Investigation of the Trex/Detrex facility in 2008-2009, two temporary monitoring wells (MW-7 and MW-8) were installed along the eastern boundary of the subject Site to assess the extent of volatile organic compound (VOC) impacts in groundwater. PCE (7 µg/L and 5 µg/L, respectively) and trichloroethene (TCE; 32 µg/L and 16 µg/L, respectively) were detected in MW-7 and MW-8 at concentrations above their respective 2L Standards of 0.7 µg/L and 3 µg/L, respectively. Therefore, H&H considered the release reported on the off -Site Trex/Detrex properties to be a REC. 3214 Cullman Avenue • The 3214 Cullman Avenue building was initially constructed in 1964 and consists of offices, restrooms, an employee break room, and warehouse space. The Site is currently vacant but was historically occupied by a beer distributor (1969), transmission supplier (1969-1974), picture frame distributor (1974-1989), chimney sweep (1979), and a printing & bindery company (1994-2014). H&H could not obtain specific reports or information documenting chemical storage or disposal practices of the former Site tenants, and details regarding the historical use and storage of chemicals on Site are unknown. Based on the lack of records or information regarding previous tenant uses, there is a potential for impact to the subject Site associated with former on -Site tenant operations. • NoDa Textiles/Newco Fibre Property (430 E. 30h Street) is located adjacent, south, and topographically upgradient of the Site. H&H reviewed a Limited Site Investigation Report prepared by Terracon dated March 30, 2015. According to the report, analysis of a groundwater sample collected from temporary monitoring well B-1 installed in the 3 hart "%; hickman https://harthick.shmepoint.com/sites/MasterFiles-I/Shared Documents/AAA-Master Projects/Avery Hall Investments (AHI)/AHI-007 Cullman Avenue Brownfields/Addiow Phase Il ESA/Report/Additional Phase II ESA_Beaty's Bindery - Final.docx SMARTEN ENVIRONMENTAL SOLUTIONS northwestern portion of the NoDa Textiles property (approximately 150 ft southwest and cross -gradient to upgradient the subject Site) reported PCE at a concentration above the 2L Standard. Based on the relatively close distance upgradient of the subject Site, and the detection of similar VOC constituents on the adjacent former Inx facility located adjacent and west of the subject Site, there appears to be a potential for impact to the Site. Therefore, H&H considered the VOC release reported at the former NoDa Textiles property to be a REC. 300 E. 36th Street • L&N Tire facility (currently Parrish Tire Co., 300 E 30h Street) - is listed in the Leaking Underground Storage Tank (LUST) database (Incident # 16670). Soil impacts were identified in 1990 during the removal of a 1,000-gallon diesel underground storage tank (UST). According to historical reports, approximately 200 cubic yards of impacted soil were over -excavated after removal of the UST, and analysis of two post -excavation soil samples indicated the impacted soil had successfully been excavated. On August 16, 1990, DEQ issued a no further action (NFA) for the release incident and requested a remedial plan for the excavated soil. The approximately 200 cubic yards of impacted soil removed from below the UST were stockpiled on the property and underneath plastic, and was tilled in good weather and allowed to volatilize to reduce impacts. L&N Tire subsequently requested that the soil be approved to reuse on Site to cover a railway side track. In 1991, DEQ issued a Certificate of Approval for Disposal of Petroleum Contaminated Soils for spreading of the soil over a rail spur at a thickness of approximately one -foot deep. Although H&H was unable to locate a NFA letter for this incident, review of the DEQ UST Section on-line database indicates that the incident received a NFA in August 1990. H&H reviewed a 2019 Phase I ESA report prepared by Bunnell Lammons Engineering (BLE) who identified the potential for petroleum impacted soil to remain along the rail spur as a REC. BLE identified the removed former UST to be a historical REC (HREC). 4 hart '` hickman https://harthick.shmepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Avery Hall Investments (AHI)/AHI-007 Cullman Avenue Brownfields/Addiow Phase Il ESA/Report/Additional Phase II ESA_Beaty's Bindery - Final.docx SMARTEN ENVIRONMENTAL SOLUTIONS • During the 2019 Phase I ESA, BLE also identified oil stains from air compressors located on a loading dock on the southside of the 300 E. 36th Street building and ground surface below to be a REC. Between December 5 and 17, 2020, H&H conducted Phase II ESA soil, groundwater, soil gas, and sub -slab vapor sampling activities at the Site to assess the above noted RECs. A brief summary of the Phase II ESA sampling results is provided below, and the Phase II ESA sample locations are shown on Figure 2. Soil • Benzo(a)pyrene was detected in soil sample SB-5 (0.5-1.5 ft) collected adjacent to a loading dock and behind the 3214 Cullman Avenue building at an estimated concentration above the Residential and Protection of Groundwater (POG) Preliminary Soil Remediation Goals (PSRGs). Benzo(a)anthracene was also detected in the SB-5 (0.5-1 ft) sample at a concentration above the POG PSRG. No additional semi-VOCs (SVOCs), VOCs, or organochlorine pesticides (OCPs) were detected at concentrations above PSRGs in the remaining soil samples collected at the Site. • Arsenic (ranging from an estimated J flag value of 1.0 J mg/kg to 8 mg/kg) was detected at concentrations above the Residential PSRG in all of the soil samples analyzed for metals (SB-2, SB-3, SB-4, SB-5, SB-6, and SB-7). Additionally, arsenic was detected above the Industrial/Commercial PSRG in soil samples collected from SB-2, SB-4, SB-5, SB-6, and SB-8. The detected arsenic concentrations are within the published range of background concentrations for North Carolina soil. However, the arsenic detection in the SB-5 (0.5- 1.5 ft) soil sample may be indicative of a possible release when evaluating the SVOC impacts also reported in the SB-5 (0.5-1.5 ft) soil sample. • Hexavalent chromium (ranging from 0.46 J to 1.4 mg/kg) was detected at concentrations above the Residential PSRG, but below the Industrial/Commercial PSRG in soil samples 5 hart '` hickman https://harthick.shmepoint.com/sites/MasterFiles-I/Shared Documents/AAA-Master Projects/Avery Hall Investments (AHI)/AHI-007 Cullman Avenue Brownfields/Addiow Phase Il ESA/Report/Additional Phase II ESA_Beaty's Bindery - Final.docx SMARTEN ENVIRONMENTAL SOLUTIONS SB-1 through SB-4, and SB-7. H&H could not locate published background concentrations for hexavalent chromium in North Carolina soils. It is possible that hexavalent chromium is potentially present in background soil. However, ink manufacturing and printing activities were previously conducted by former tenants that operated on the 3210 Cullman Avenue property. Therefore, the presence of hexavalent chromium in soil on the western portion of the Site as a result of previous anthropogenic activity cannot be ruled out. • Additional metals, including barium, cadmium, lead, mercury, selenium, and silver were detected at concentrations below PSRGs, and/or were generally consistent with published average background levels for North Carolina soils. Groundwater • The VOC PCE was detected in the TMW-1 and TMW-2 groundwater samples collected in the western and southwestern portions of the Site at concentrations above the 2L Standard. In addition, naphthalene (reported as both a VOC and SVOC) was detected in the TMW-5 groundwater sample collected in the southeastern portion of the Site at concentrations above the 2L Standard of 6 µg/L. Additional VOCs, SVOCs, or metals were not detected above 2L Standards in the remaining groundwater samples collected at the Site. • Cumulative risk calculations inputting "worst case" groundwater data indicate that the carcinogenic risk levels are below both residential and non-residential exposure scenarios for groundwater. The "worst case" calculations indicate an unacceptable non -carcinogenic risk under a residential use scenario and an acceptable non -carcinogenic risk under a non- residential use scenario. Based on results of the groundwater risk calculations, vapor intrusion does not appear to pose a significant risk to current tenants of the existing commercial buildings. However, a vapor intrusion exposure risk exists for any future residential use or proposed redevelopment of the Site based on the results of the groundwater risk calculations. 6 hart '` hickman https://harthick.shmepoint.com/sites/MasterFiles-I/Shared Documents/AAA-Master Projects/Avery Hall Investments (AHI)/AHI-007 Cullman Avenue Brownfields/Addiow Phase Il ESA/Report/Additional Phase II ESA_Beaty's Bindery - Final.docx SMARTEN ENVIRONMENTAL SOLUTIONS Soil Gas and Sub -Slab Vapor • Laboratory analytical results indicate that chloroform was detected at a concentration in soil gas sample SGV-1 collected in the western portion of the Site above the Residential and the Non -Residential Soil Gas Screening Levels (SGSLs). Additionally, benzene was detected in soil gas sample SGV-1 at a concentration above the Residential SGSL, but below the Non -Residential SGSL. No other VOCs were detected at concentrations above SGSLs in the SGV-1 soil gas sample. • No VOCs were detected at concentrations above SGSLs in the SSV-1 to SSV-5 samples collected below the concrete floor of the 3214 Cullman Avenue and 300 E. 36t' Street buildings. • The calculated lifetime incremental cancer risk (LICR) for the combined "worst case" soil gas and sub -slab vapor sample results were within the acceptable risk range of 1 x104 to 1 x 10-6 under both a residential and non-residential use scenario. Additionally, the calculated non -carcinogenic Hazard Index (HI) risk for the combined "worst case" soil gas and sub -slab vapor samples does not indicate a potential for vapor intrusion at unacceptable risk levels (HIs of > 1) under a residential or non-residential use scenario. Although the calculations indicate acceptable carcinogenic and non -carcinogenic risks under both residential and non-residential use scenarios for the samples collected at the Site, H&H recommends installation of a vapor mitigation system below future Site buildings due to the presence of chlorinated solvent impacts reported in groundwater both on the Site, and on nearby properties located topographically cross -gradient (west) and upgradient (south) of the Site. Based on the results of the Phase II ESA and to address data gaps which may be requested by the DEQ Brownfields Program, H&H conducted additional Phase II ESA sampling activities at the Site. The methods and results of the additional Phase II ESA activities are summarized in the following sections. 7 hart '` hickman https://harthick.shmepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Avery Hall Investments (AHI)/AHI-007 Cullman Avenue Brownfields/Addiow Phase Il ESA/Report/Additional Phase II ESA_Beaty's Bindery - Final.docx SMARTEN ENVIRONMENTAL SOLUTIONS 2.0 Additional Phase II ESA Activities On August 9 and 10, 2022, H&H conducted additional Phase II ESA soil, soil gas, and sub -slab vapor sampling activities at the Site. A summary of the additional Phase II ESA activities is presented below, and the additional Phase II ESA sample locations are depicted on Figure 2. 2.1 Utility Locating/Geophysical Survey Utility Location Prior to conducting additional Phase II ESA sampling activities, H&H contacted North Carolina One -Call, the public utility locator, to mark subsurface utilities located on the Site. H&H also contracted a private utility locator, Integrated Scanning Solutions, LLC (ISS), to screen the proposed sample locations using ground -penetrating radar (GPR) and electromagnetic (EM) methods. 2.2 Soil Sampling Activities H&H advanced a total of nine (9) borings to assess potential impacts at the following locations on the subject Site: • S13-5 was advanced adjacent to the 3214 Cullman Avenue building's loading dock in an attempt to delineate the vertical extent of polynuclear aromatic hydrocarbons (PAHs) and potential metal impacts previously detected in SB-5 (0.5-1.5 ft); • SB-10 through SB-12 were advanced at locations adjacent to the 3214 Cullman Avenue building's loading dock to further delineate the horizontal extent of apparent PAHs and potential metal impacts detected in the area of the previously sampled S13-5 (0.4.5 ft) soil boring; and • SB-13 through SB-17 were advanced throughout the Site to collect soil samples for Brownfields characterization. 8 hart '` hickman https://harthick.shmepoint.com/sites/MasterFiles-I/Shared Documents/AAA-Master Projects/Avery Hall Investments (AHI)/AHI-007 Cullman Avenue Brownfields/Addiow Phase Il ESA/Report/Additional Phase II ESA_Beaty's Bindery - Final.docx SMARTEN ENVIRONMENTAL SOLUTIONS A hand auger was used to advance each soil boring to partially -weathered rock (PWR) which was encountered across the Site at depths ranging from approximately 3.5 to 5 feet below ground surface (ft bgs). Soil from the borings was screened in the field for the presence of odors, staining, and/or elevated photoionization detector (PID) readings. Based upon field screening results, H&H collected one soil sample from the SB-5 and SB-10 through SB-17 soil borings for laboratory analysis. Soil samples were selected based on evidence of impact during field screening activities, or the sample interval with the highest potential for impact for laboratory analysis (e.g., shallow sample for assessment of surficial spills). If no potential impacts were identified, a soil sample was collected from the same depth interval as the initial SB-5 soil sample (0.5-1.5 ft bgs). Field screening results did not indicate the presence of obvious impacts in soil screened from the borings. The soil samples were collected from the following depths: • SB-11 through SB-14 were collected at a depth interval of 0.5-1.5 ft bgs; • SB-15 through SB-16 were collected at a depth interval of 1-2 ft bgs; • SB-17 was collected at a depth interval of 2-3.5 ft bgs; and • SB-5 and SB-10 were collected at a depth of 3-4ft bgs. Soil lithology and boring logs (including PID readings) for the soil borings are included in Appendix A. The soil boring locations are depicted on Figure 2. Soil samples were placed directly into laboratory -supplied glassware, labeled, and placed on ice in a laboratory -supplied cooler. The samples were delivered to Waypoint Analytical, LLC (Waypoint), a North Carolina -certified laboratory, under standard chain of custody protocols for analysis of VOCs by EPA Method 8260, SVOCs by EPA Method 8270, and Resource Conservation and Recovery Act (RCRA) Metals by EPA Methods 6020/7471 plus hexavalent chromium by EPA Method 7196 for speciation. Following sampling activities, the soil borings were abandoned, and the ground surfaces were patched to match pre -sampling conditions. 9 hart '` hickman https://harthick.shmepoint.com/sites/MasterFiles-I/Shared Documents/AAA-Master Projects/Avery Hall Investments (AHI)/AHI-007 Cullman Avenue Brownfields/Addiow Phase Il ESA/Report/Additional Phase II ESA_Beaty's Bindery - Final.docx SMANTER ENVIRONMENTAL SOLUTIONS 2.3 Soil Gas and Sub -Slab Sampling Activities Two (2) soil gas points and three (3) sub -slab vapor points were installed at the Site in the following locations: 3210 Cullman Avenue • One (1) soil gas point (SGV-2) was installed at the 3210 Cullman Avenue property to evaluate soil gas conditions in the western portion of the Site within the proposed footprint of the future Site building. 3214 Cullman Avenue • One (1) soil gas point (SGV-3) was installed at the 3214 Cullman Avenue property to evaluate soil gas conditions in the central portion of the Site within the proposed footprint of the future Site building. 300 E. 36" Street • Three (3) sub -slab vapor points (SSV-6 through SSV-8) were installed in the 300 E. 361 Street building to evaluate the potential for vapor intrusion in the eastern portion the Site within the proposed footprint of the future Site building. The soil gas and the sub -slab vapor sample locations are included on Figure 2. Soil Gas On August 9, 2022, H&H installed the SGV-2 and SGV-3 soil gas points to depths of approximately 5.5 ft bgs using a decontaminated stainless -steel hand auger for collection of a soil gas sample. During advancement of each soil gas sample boring, soil recovered from the hand auger was described for lithologic purposes, and was screened for the presence of odors, staining, and for organic vapors using a calibrated PID. The soil gas points were installed with a 6-inch 0.010-inch stainless steel screen set at the base of the boring connected to the surface with'/4-inch Teflon tubing. The annular space was filled with filter sand to approximately 6-inches above the 10 hart 'hickman https://harthick.shmepoint.com/sites/MasterFiles-I/Shared Documents/AAA-Master Projects/Avery Hall Investments (AHI)/AHI-007 Cullman Avenue Brownfields/AdditiW` Phase II ESA/Report/Additional Phase II ESA_Beaty's Bindery - Final.docx SMAUER ENVIRONMENTAL SOLUTIONS stainless -steel screen, followed by a hydrated granular bentonite seal to prevent short-circuiting of air from the surface. The soil gas points were allowed to equilibrate for approximately 24 hours following installation. Sub -Slab Vapor On August 9, 2022, H&H installed sub -slab vapor points SSV-6 through SSV-8 into the concrete floor of the 300 E. 36t' Street building using Cox Colvin Vapor PinTM (Vapor Pin) kits. To install the Vapor Pins, H&H used a hammer drill to install a countersunk 1.5-inch diameter hole into the concrete slab to a depth of approximately 1.75 inches. Following advancement of the countersunk hole, a drill guide was placed in the hole and a hammer drill equipped with a 5/8-inch diameter bit was used to further advance the borehole through the concrete slab and approximately 6 inches into the underlying soil. Following borehole advancement, loose cuttings were removed. Then, the Vapor Pin assembly (brass sampling point and silicone sleeve) was placed and seated in the drilled hole by tapping the assembly into place using the installation/extraction tool and a dead blow hammer. Vapor Sampling Activities Prior to collection of the sub -slab and soil gas vapor samples, H&H completed leak checks for each sample point. H&H performed the leak checks by first placing a shroud over each sample point and sample train, filling the shroud with helium gas, and using a helium gas detector to verify that the shroud was saturated with helium gas. Then, the sample points were purged using an air sampling pump and a three-way valve to collect purged vapor into a Tedlar® bag. The purged vapor at each sample point was subsequently analyzed using the helium gas detector to ensure that helium concentrations were less than 10% of the helium concentrations in the shroud. Following a successful leak check, the soil gas and the sub -slab vapor samples were collected using 1.4-liter Summa® canisters. The Summa® canisters were connected to the Vapor Pin via Teflon® tubing and a nut and ferrule assembly. The Summa® canisters were allowed to fill at a rate of approximately 100 milliliters per minute (mL/min) using an airflow regulator. The vacuum 11 hart '` hickman https://harthick.shmepoint.com/sites/MasterFiles-I/Shared Documents/AAA-Master Projects/Avery Hall Investments (AHI)/AHI-007 Cullman Avenue Brownfields/Addiow Phase Il ESA/Report/Additional Phase II ESA_Beaty's Bindery - Final.docx SMARTEN ENVIRONMENTAL SOLUTIONS pressure in each Summa canister upon completion of each sample was between four (4) and seven (7) inches of mercury (in Hg). During sample collection, H&H collected measurements of ambient temperature at the beginning, middle, and end of the sample collection period in the general areas of the sub -slab vapor samples. Following sample collection, the Summa® canisters were shipped under standard chain -of -custody protocols to Waypoint, a North Carolina -certified laboratory under chain of custody protocols for analysis of VOCs by EPA Method TO-15. 12 hart '` hickman https://harthick.shmepoint.com/sites/MasterFiles-I/Shared Documents/AAA-Master Projects/Avery Hall Investments (AHI)/AHI-007 Cullman Avenue Brownfields/Addiow Phase Il ESA/Report/Additional Phase II ESA_Beaty's Bindery - Final.docx SMARTEN ENVIRONMENTAL SOLUTIONS 3.0 Phase II ESA Sample Results 3.1 Soil Sample Results Soil analytical results were compared to DEQ Inactive Hazardous Site Branch (IHSB) Preliminary Soil Remediation Goals (PSRGs) for Protection of Groundwater (POG), unrestricted use (Residential), and Commercial/Industrial use.

No additional SVOCs were detected above laboratory detection limits in the soil samples collected at the Site. Metals Arsenic (ranging from an estimated J flag value of 1.55 J mg/kg to 12.4 mg/kg) was detected at concentrations above the Residential PSRG of 0.68 mg/kg in the soil samples collected at the Site during the additional Phase II ESA activities. Additionally, arsenic was detected above the Commercial/Industrial PSRG of 3.0 mg/kg in soil sample S13-12 (0.5-1.5 ft bgs) at a concentration of 12.4 mg/kg. The detected arsenic concentrations are within the published range of background concentrations for North Carolina soil of 1.0 to 18 mg/kg. However, the arsenic detection in the SB-12 (0.5-1.5 ft bgs) soil sample may be indicative of a potential release related to the former loading dock area. Hexavalent chromium (ranging from 0.397 J to 2.10 mg/kg) was detected at concentrations above the Residential PSRG of 0.31 mg/kg but below the Industrial/Commercial PSRG of 6.5 mg/kg in soil samples SB-11 through SB-14, and SB-17. H&H could not locate published background concentrations for hexavalent chromium in North Carolina soils. It is possible that hexavalent chromium is potentially present in background soil. However, ink manufacturing and printing activities were previously conducted by former tenants that operated on the 3210 Cullman Avenue property. Therefore, the presence of hexavalent chromium in soil on the western portion of the Site as a result of previous anthropogenic activity cannot be ruled out. 14 hart ` hickman https://harthick.shmepoint.com/sites/MasterFiles-I/Shared Documents/AAA-Master Projects/Avery Hall Investments (AHI)/AHI-007 Cullman Avenue Brownfields/Addiow Phase Il ESA/Report/Additional Phase II ESA_Beaty's Bindery - Final.docx SMARTEN ENVIRONMENTAL SOLUTIONS Additional metals, including barium, cadmium, lead, and mercury, were detected at concentrations below PSRGs, and/or were generally consistent with published average background levels for North Carolina soils. 3.2 Soil Gas and Sub -Slab Sample Results Laboratory analytical results of the soil gas and the sub -slab vapor samples were compared to the DEQ DWM Residential and Non -Residential SGSLs dated July 2022. These screening levels are very conservative and are based upon a LICR of 1 x 10` for potential carcinogenic effects and/or a HI of 0.2 for potential non -carcinogenic effects. Vapor intrusion mitigation for occupied structures is not typically considered unless the LICR exceeds the acceptable risk of 1 x 10-4 for potential carcinogenic effects and a HI of 1 for potential non -carcinogenic effects. Analytical results of the soil gas and sub -slab samples collected at the Site are summarized in Table 4, and the laboratory analytical reports are included in Appendix B. Soil Gas Vapor Laboratory analytical results indicate that chloroform was detected at estimated concentrations of 9.91 J micrograms per cubic meter (µg/m3) and 16.3 J µg/m3 in soil gas samples SGV-2 and SGV- 3, respectively, which exceed the Residential SGSL of 4.1 µg/m3 but is below the Non -Residential SGSL of 53 µg/m3. Additionally, ethylbenzene was detected at a concentration of 42.9 µg/m3 in soil gas sample SGV-2, which is above the Residential SGSL of 37 µg/m3, but is below the Non - Residential SGSL of 160 µg/m3. No other VOCs were detected at concentrations above SGSLs in the SGV-2 and SGV-3 soil gas samples. Sub -Slab Vapor The VOC naphthalene was detected above the Residential SGSL of 2.8 µg/m3 but below the Non - Residential SGSL of 36 µg/m3 in all sub -slab vapor samples collected at the Site (ranging from 4.15 µg/m3 to 6.06 µg/m3). No additional VOCs were detected at concentrations above SGSLs 15 hart ` hickman https://harthick.shmepoint.com/sites/MasterFiles-I/Shared Documents/AAA-Master Projects/Avery Hall Investments (AHI)/AHI-007 Cullman Avenue Brownfields/Addiow Phase Il ESA/Report/Additional Phase II ESA_Beaty's Bindery - Final.docx SMARTEN ENVIRONMENTAL SOLUTIONS in the SSV-1 through SSV-8 samples collected below the concrete slab of the 3214 Cullman Avenue and 300 E. 36th Street buildings. 16 hart ` hickman https://harthick.shmepoint.com/sites/MasterFiles-I/Shared Documents/AAA-Master Projects/Avery Hall Investments (AHI)/AHI-007 Cullman Avenue Brownfields/Addiow Phase Il ESA/Report/Additional Phase II ESA_Beaty's Bindery - Final.docx SMARTEN ENVIRONMENTAL SOLUTI0NS 4.0 Risk Calculations H&H preformed risk calculations to further assess soil gas and sub -slab vapor results. Summaries of the risk calculations are presented below and copies of the risk calculations are included in Appendix C. Vapor Risk Calculations To further evaluate the detected compounds, H&H input the concentrations of the "worst case" detected VOCs from the soil gas samples and from the SSV-1 to SSV-8 sub -slab vapor samples into the DEQ Risk Calculator (July 2022 Version) to calculate a cumulative potential carcinogenic and non -carcinogenic risks for the vapor samples collected during recent Additional Phase II ESA activities. Calculations using "worst case" compounds were run for both residential and non- residential use scenarios of the soil gas to indoor air exposure pathway.
