The site encompasses three contiguous parcels (Mecklenburg County Tax Parcel Nos. 12103308, 12103309 and 12103310) for a total area of approximately 0.75 acres. The Carolina Foundry site is generally bound to the south by West Tremont Avenue while the surrounding properties are developed as industrial/commercial. According to the National Wetland Inventory (NWI) online database, the nearest surface water feature is an unnamed tributary of Irwin Creek, located approximately 600 feet north of the site. The site as shown on Figure 1 was accepted into the North Carolina Brownfields Program on August 2, 2016 with Barringer Capital, LLC identified as the prospective developer (PD). 1.2 Site History Terracon performed a review of historical documents available for the site, including a Phase I Environmental Site Assessment (ESA) completed by Geoscience Group, Inc. (Geoscience) in 2015 for the former foundry facility. Terracon also reviewed available aerial photographs to gain a general understanding of the development history of the property. The history of the site is discussed below. Two of the on-site parcels (12103309 and 12103310) consist of a single-story building that was formerly occupied by Carolina Foundry, which operated as an aluminum, brass, and copper casting facility. The third parcel (12103308) contains a separate single-story building that was used for storage. According to the 2015 Phase I ESA by Geoscience, the storage building was constructed in the early 1990s and the foundry building was built in the mid-1950s. The foundry was active from at least 1949. According to the historical information, the property was undeveloped prior to approximately 1930. In conjunction with the 2015 Phase I ESA, Geoscience collected nine soil samples beneath the concrete floor slab of the foundry building. Samples were collected from areas of the building that included two machine shops, adjacent to an underground heating oil storage tank, adjacent to the foundry furnaces, and within the air compressor room where ponded oil was observed on the Brownfields Assessment Report Carolina Foundry Brownfields Site ■ Charlotte, NC March 14, 2017 ■ Terracon Project No. 71167563 Responsive ■Resourceful ■Reliable 2 concrete floor. The 2015 sample locations are shown on Figure 2, and the sampling results are included in Table 2 (taken from the Geoscience Phase I ESA). Note that samples were not collected from sample locations S-3 (near the heating oil UST) and S-8 (casting area) due to obstructions, and two samples were obtained from sample location S-5 at different depths (S-5 and S-5A). The nine soil samples (S-1, S-2, S-4, S-5, S-5A, S-6, S-7, S-9 and S-10), were collected at depths ranging from 1.5 to 8 feet below ground surface (bgs), and were analyzed for volatile organic compounds (VOCs) by EPA Method 8260, semi-volatile organic compounds (SVOCs) by EPA Method 8270 and RCRA metals. Petroleum-related VOCs were detected in soils near the furnaces and the former heating oil UST at concentrations that did not exceed the Residential Health Based Preliminary Soil Remediation Goals (PSRGs). Various SVOC constituents were also detected in samples S-1 through S-5A. Benzo(a)pyrene, benzo(a)anthracene, benzo(b)fluoranthene, and indeno(1,2,3-cd)pyrene) were detected in samples S-1 and S-2 above Residential PSRGs. Samples S-1 and S-2 were obtained in the machine shop area (eastern portion of foundry building) which is currently planned for development as an access driveway/road (Figures 2 and 7). Other PAH compounds (naphthalene, 1-methylnaphthalene, and 2-methylnaphthalene) were detected near the former UST and the furnaces (S-4 and/or S- 5/5A) above Protection of Groundwater PSRGs but below Residential PSRGs. Various RCRA metals were detected in the soils at the site below residential PSRGs; however, arsenic was detected in each sample at concentrations that exceeded the Residential or Non-Residential PSRGs. The elevated arsenic concentrations are within the typical range of naturally occurring arsenic in the Charlotte area (Geochemical Landscapes of the Conterminous United States — New Map Presentations for 22 Elements, USGS, 2001). As part of the Phase I ESA, Geoscience also collected two representative samples from the waste foundry sand stockpiled inside the former foundry building to characterize the foundry sand for disposal. One sample was obtained from the foundry sand stockpiled in the casting area, and one composite sample was taken from the waste foundry sand stockpile (labeled as “Former Waste Sand Stockpile” on Figure 2). The samples contained diesel range organics (DRO) at 2,900 mg/kg (foundry floor) and 2,000 mg/kg (waste sand stockpile). Gasoline range organics (GRO) at 23 mg/kg and benzene, toluene, ethylbenzene, and xylenes (BTEX) were detected in the foundry floor sample. BTEX and GRO constituents were not detected in the waste pile sample. Toxicity Characteristic Leachate Procedure (TCLP) metals analyses from both stockpiles indicated the presence of cadmium and lead at levels below characteristic hazardous waste criteria. Terracon understands that the stockpiled foundry sands have been removed from the site. A 1,000-gallon underground heating oil storage tank was formerly located inside the foundry building as shown on Figure 2. The tank was removed in January 2016 by Environmental Compliance Services of NC (ECS). ECS submitted an Initial Abatement Action Report describing the tank removal activities to the UST Section of the North Carolina Department of Environmental Brownfields Assessment Report Carolina Foundry Brownfields Site ■ Charlotte, NC March 14, 2017 ■ Terracon Project No. 71167563 Responsive ■Resourceful ■Reliable 3 Quality (NCDEQ). According to the report, petroleum-impacted soils were detected near the tank. After removal of the tank and impacted soils, confirmation samples were collected from the excavation to confirm the removal of the impacted soils. Groundwater was not encountered during the tank removal activities. Laboratory analyses of samples collected at the bottom of the excavation approximately six feet below ground surface (bgs), detected DRO constituents at concentrations above the current regulatory action level of 100 milligrams/kilogram (mg/kg). VOCs and several other petroleum compounds were present in the confirmation soil samples at levels below their respective Residential Maximum Soil Contaminant Concentrations (MSCCs). The confirmation sample locations (SS-1 and SS-2) are shown on Figure 2, and the sampling results are included in Table 2 (taken from the ECS Initial Abatement Action Report). Following tank removal activities, ECS filed a Notice of Residual Petroleum for the release at the UST at the Mecklenburg County Register of Deeds. The Notice of Residual Petroleum included a land use restriction that prohibits the use of groundwater at the site. The NCDEQ issued a No Further Action Letter for the UST release on March 1, 2016. Off-Site Environmental Concerns The former Carolina Foundry is bordered by multiple facilities that have entered into the NC Brownfields Program. Based on topography and its location relative to the site, it is possible that impacted groundwater from the nearby Tremont Redevelopment property (NC Brownfields #18004-14-060) could migrate towards the site. 1.3 Preliminary Redevelopment Plans The PD’s current redevelopment plans are to demolish the existing on-site buildings and construct as many as 18 residential townhome units, grouped into three buildings. Redevelopment plans also include paved access driveways, as shown on Figures 2 and 7. 2.0 SCOPE OF SERVICES Terracon conducted the Brownfields Assessment activities in general accordance with the Brownfields Assessment Work Plan, revised November 29, 2016, approved by the NC Brownfields Program Project Manager on December 1, 2016. Several minor scope modifications regarding the collection of soil samples were discussed during a meeting at the site on January 9, 2017 with Brownfields Project Managers Ms. Jordan Thompson and Ms. Carolyn Minnich due to conditions encountered at the site. These scope modifications were approved by the Brownfields Project Manager and documented in an addendum letter dated January 12, 2017. The scope of services conducted at the facility included: §Preparation of a Health and Safety Plan and underground utility clearance; §Installation of three temporary groundwater monitoring wells; Brownfields Assessment Report Carolina Foundry Brownfields Site ■ Charlotte, NC March 14, 2017 ■ Terracon Project No. 71167563 Responsive ■Resourceful ■Reliable 4 §Groundwater sample collection from the temporary monitoring wells; §Collection of eight soil samples at the site; §Installation of seven sub-slab soil vapor sample points at locations inside the buildings near the former UST, the furnace area, the mold preparation area, the sand mixer, the southern machine shop and storage areas for collection of soil vapor samples; and, §Completion of a Brownfields Receptor Survey. Sample locations are shown on Figure 2 and are summarized in Table 1. Field methods are discussed in Section 3 of this report. 2.1 Reliance This report has been prepared for the exclusive use of Barringer Capital, LLC and the North Carolina Brownfields Program. Any authorization for use or reliance by another party (except a governmental entity having jurisdiction over the site) is prohibited without the expressed written authorization of Barringer Capital, LLC and Terracon. Any unauthorized distribution or reuse is at the sole risk of Barringer Capital, LLC. Reliance by authorized parties will be subject to the terms, conditions, and limitations stated in the proposal, report, and Terracon’s Agreement for Services. The limitation of liability defined in the terms and conditions is the aggregate limit of Terracon’s liability to Barringer Capital, LLC and all relying parties unless otherwise agreed in writing. 3.0 FIELD INVESTIGATION METHODS Terracon conducted the field work in accordance with a health and safety plan developed for this project. Work was performed using United States Environmental Protection Agency (USEPA) Level D work attire consisting of hard hats, safety glasses, protective gloves, and protective boots. 3.1 Temporary Well Installation Prior to intrusive activities, Terracon submitted a locate request to the public utility locator [NC 811] to arrange for location of underground public utilities from the street to the utility meter. As an added measure of safety, Terracon subcontracted Probe Utility Locating of Huntersville, North Carolina, a private utility locator, to identify and mark public utilities beyond the meter as well as additional site utilities identified near the proposed boring locations on January 9, 2017. Terracon mobilized to the site on January 9, 2017 to install three temporary groundwater monitoring wells GW-01, GW-02, and GW-03 (Figure 2 and Table 3) to evaluate groundwater quality and determine the groundwater flow direction and hydraulic gradient at the site in the general areas outlined in the Brownfields Assessment Work Plan. Redevelopment plans for the Brownfields Assessment Report Carolina Foundry Brownfields Site ■ Charlotte, NC March 14, 2017 ■ Terracon Project No. 71167563 Responsive ■Resourceful ■Reliable 5 site do not include the use of on-site groundwater for any purpose and it is not anticipated that groundwater will be encountered during redevelopment activities. The boreholes were drilled by Innovative Environmental Technologies (IET) using Direct Push Technology (DPT) drilling methods. Prior to advancing each boring, the drill tooling was cleaned to prevent cross-contamination of samples. Boreholes for the wells were advanced to the water table or DPT refusal, whichever was encountered first. The wells were constructed with a 1-inch diameter PVC riser and a 10-foot screen to a total depth between 20 and 24 feet bgs. A sand filter pack was placed in the annulus, extending from the bottom of the well screen to about one foot above the top of the well screen. Hydrated bentonite was then used to create a 2-foot thick seal above the filter pack. Well construction details are provided in Table 3. Terracon surveyed the horizontal and vertical locations of the temporary monitoring wells so the groundwater flow direction and hydraulic gradient could be calculated. 3.2 Groundwater Sampling Terracon collected groundwater samples from two of the three temporary monitoring wells (GW- 02 and GW-03) on January 11, 2017. After multiple attempts to develop temporary well GW-01 due to the presence of mud clogging the well, Terracon re-mobilized to the site on January 16, 2017 to install a replacement for well GW-01 using a 4-inch diameter borehole and placement of a thicker sand pack around the well screen. Prior to sample collection, Terracon gauged the groundwater elevations in the monitoring wells using a clean electronic water level indicator. Depth to groundwater ranged from 7.08 feet below ground surface (bgs) in well GW-02 to 13.19 feet bgs in well GW-03. Groundwater elevation measurements and monitoring well construction information are provided in Table 3. Based on the water level measurements, groundwater flow direction is generally towards the northeast. The wells were purged using a peristaltic pump and low-flow sampling methods until field parameters of temperature, pH, oxidation-reduction potential, specific conductance, and dissolved oxygen had stabilized. Groundwater sample collection records are provided in Appendix A. The wells were generally purged at least two well volumes using low-flow methods prior to sampling. Due to the physical properties of the 1-inch diameter temporary monitoring wells with groundwater sample collection from temporary monitoring wells, development to less than 10 NTU for turbidity was not feasible for temporary well GW-03, which was collected at 24 NTU. A duplicate groundwater sample (DUP-02-011117) was collected at well GW-02 The groundwater samples were placed in laboratory-supplied glassware, labeled and stored in an ice-packed cooler. The samples, a trip blank for QA/QC purposes, and the chain-of-custody documentation, were delivered to Pace Analytical Services, Inc. in Huntersville, North Carolina for analysis of volatile organic compounds (VOCs) by EPA Method 8260, semi-volatile organic compounds (SVOCs) by EPA Method 8270, and RCRA metals by EPA Methods 6010 and 7470, including aluminum, copper, and zinc.

The soil sample locations are shown on Figure 2. On January 10, 2017, Terracon mobilized to the site to collect eight soil samples (S-11 through S-16, BG-01, and BG-02). Terracon also collected a duplicate sample (DUP-01-011017) at the same sample location as sample S-15. Soil sample BG-01 was advanced to a depth of 2.5 feet bgs and soil borings BG-02 and S-11 through S-16 were advanced to a depth of 5 feet bgs. Soil sampling activities were conducted in the unsaturated zone only. Samples were collected in areas of the site where existing surface soils may be disturbed during redevelopment (see Figure 2 for soil sample locations and Figure 7 for the preliminary future site layout). Grading plans are not yet available but reportedly, grade cuts will be limited to less than 5 feet bgs in these areas. Soil borings were located between the storage building and the foundry building (S-11), in the paved driveway to the south of the former foundry building (S-12), between the former waste sand stockpile and the sand mixer in the foundry building (S-13), near a trench drain with containing ponded water within the former foundry building (S-14), near a large pit with a sump located in the former mold preparation area (S-15), and near a small pit located near the former machine shop (S-16). Soil samples BG-01 and BG-02 were collected to establish background metals concentrations on the site. Terracon subcontracted Innovative Environmental Technologies (IET), Inc., a North Carolina licensed drilling company to advance the borings using direct-push drilling technology and Macro- Core® samplers. IET utilized an AMS PowerProbe track-mounted drill rig. Since the location of background sample BG-01 was not accessible by the drill rig, IET used a clean, de-contaminated hand-auger to advance the boring to 2.5 feet bgs. Soil type, relative moisture content, and other lithologic characteristics documented in the field are depicted on boring logs (Appendix A). Soils consisted predominantly of red, orange and brown silty clay and clayey silt with moderate to low moisture. Groundwater was not present in the shallow soil borings; however, three of the borings were advanced to the water table. Photo-ionization detector (PID) readings did not indicate VOC impacts in the recovered soils. Terracon collected a sample from the 0 to 2 foot interval from samples S-11, S-12, S-13, BG-01, and BG-02. Terracon collected a sample from the 3 to 5 foot interval from samples S-15, S-16, and DUP-01-011017 and a sample from the 1-3 foot interval from S-14. Additional soils were collected at the locations of the four interior soil borings (S-13 through S-16) for analysis of metals by the Toxicity Characteristic Leachate Procedure (TCLP) to evaluate the soils at the facility for hazardous characteristics. The TCLP samples were placed on hold at the laboratory pending the results of the total metals analyses. After review of the total metals analyses results, the Brownfields program did not require TCLP analysis. The boreholes were abandoned using hydrated bentonite and concrete grout after the sampling activities were completed.

Chain of custody documentation accompanied the samples to the laboratory. 3.4 Soil Vapor Sample Point Installation The Brownfields Assessment Work Plan for the foundry site included the collection of seven sub- slab soil vapor samples and one blind duplicate sample collected at the location of SV-04, near the former sand mixer. The locations of the sub-slab soil vapor samples are shown on Figure 2 as SV-01 through SV-07 and are discussed below: §SV-01 and SV-07 in the building formerly used as a warehouse; §SV-02 in the mold preparation/casting area where waste sand was stockpiled; §SV-03 in the furnace area; §SV-04 adjacent to the sand mixer; §SV-05 in the southern machine shop area; and §SV-06 in the area of the kerosene AST and the former heating oil UST. Updated sample identifications, locations, and analytical methods are shown in the Sampling and Analysis Plan (Table 1) and on Figure 2. Technical approaches and methods used for the soil vapor investigation are in general accordance with the Interstate Technical and Regulatory Council’s Vapor Intrusion: A Practical Guideline (2007) and Vapor Intrusion Pathway: Investigative Approaches for Typical Scenarios (2007), as well as the NCDEQ Division of Waste Management (DWM)Vapor Intrusion Guidance (2014). On January 9, 2017, two temporary sub-slab soil vapor (SV) sampling points were installed within the storage building and five sub-slab SV sampling points were installed within the former foundry building (Figure 2). Each temporary SV sampling point was installed by drilling a 5/8-inch diameter hole through the floor slab to a depth of approximately 1 to 2 inches into the underlying soils. The concrete slab was approximately eight inches thick at sampling points SV-01 and SV- 07 and about 14 to 15 inches at sampling points SV-02 through SV-06. The existence of a moisture barrier beneath the building slab could not be verified by Terracon. The SV sampling points were completed with a Vapor Pin™ assembly consisting of a brass barb fitting with a silicone sleeve to seal the 5/8-inch diameter hole. A silicone cap was placed over the vapor pin to keep it sealed and the sample points were allowed to equilibrate overnight prior to sampling.

In order to test the integrity of the sampling point seal, both a shut-in test and a helium tracer test were conducted at each sample point. A MGD-2000 helium detector was used to verify the presence and concentration of tracer gas. The protocol for using a tracer gas is to enclose the sample manifold, tubing and ground interface with a shroud and enrich the shroud atmosphere with helium. Prior to sample collection, at least three volumes of the vapor point annulus and attached Teflon® lined tubing and sample train were purged using a vacuum canister. Purge samples were then screened for helium to assess the presence of leaks in the seal and fittings and with a PID to assess for the presence of VOCs. Sample collection was started if the tracer testing indicated the helium concentration in the vapor point was less than 10 percent of the helium concentration in the shroud, indicating an appropriately sealed vapor point annulus. Samples were collected with 1.0-liter Summa® canisters equipped with 170 ml/min flow controllers for analysis of VOCs per EPA Method TO-15. In addition to the tracer test performed in the field, one sample (SV-07) was analyzed for helium by Method ASTM-1946 to quantify leakage. None of the seven SV points exhibited leakage during field leak testing. A blind duplicate sample was collected at sample point SV-04. The vacuum pressure of the sample canisters was monitored and recorded at regular intervals throughout the sampling period. Field sample collection records for soil vapor samples are provided in Appendix A. After completion of soil vapor sampling activities, the vapor sample points were abandoned by removal of the vapor pin and silicone sleeve and filling the borehole with neat cement grout to the slab surface. Following completion of the field activities, the Summa canisters (eight samples including the duplicate), along with chain-of-custody documentation, were shipped to Eurofins AirToxics in Folsom, California for laboratory analysis of VOCs by United States Environmental Protection Agency (EPA) Method TO-15 and ASTM-1946 (SV-07 only). 3.6 Brownfields Receptor Survey Terracon completed a Brownfields Receptor Survey which was completed on the form provided by the NC Brownfields Program as a part of the additional assessment for the site. The Brownfield Program’s “Brownfields Receptor Survey” form was used to conduct the field- and office-based portions of the receptor survey. Terracon did not identify private or public water supply wells or private irrigation wells within 1,500 feet of the site. The nearest surface water is an unnamed tributary of Irwin Creek, located approximately 600 feet north of the site. The completed form is included in Appendix A.

The following sections describe the sample results. 4.1 Site Hydrogeology Groundwater levels measured in the three on-site temporary monitoring wells ranged from 7.08 feet bgs (GW-02) to 13.19 feet bgs (GW-03). Groundwater elevations were calculated using the field measurements and the top of casing and ground elevation data. Groundwater depths and elevations are reported in Table 3. A groundwater elevation contour map is provided as Figure 3. Groundwater in the surficial aquifer appears to be flowing towards the northeast. The horizontal hydraulic gradient is approximately 0.054 ft./ft. at the former foundry site. 4.2 Groundwater Sample Results On January 10, 11, and 17, 2017, groundwater samples were collected from three temporary monitoring wells at the site. Laboratory analytical results for VOCs, SVOCs, and RCRA metals are discussed separately below. Groundwater sample analytical results are summarized in Table 4 and on Figure 5. The laboratory analytical reports are included in Appendix B. Groundwater sample results were compared to the North Carolina Administrative Code Subchapter 2L Groundwater Quality Standards (2L Standard), effective April 1, 2013. VOCs Methylene chloride was detected in samples GW-02 (2.0 micrograms per liter [µg/L]), GW-03 (1.9J µg/L), and DUP-02-011117 (2.0 µg/L) at concentrations below the 2L Standard of 5 µg/L. Styrene was also detected in samples GW-02 (0.30J) and DUP-02-011117 (0.39J) below the 2L Standard. Styrene and methylene chloride are also below the DWM Residential Groundwater Vapor Intrusion Screening Level of 1,860 µg/L and 942 µg/L, respectively. Sample GW-01 did not contain VOC constituents above laboratory reporting limits. SVOCs Diethylphthalate was detected in samples GW-01 (7.9J µg/L) and DUP-02-011117 (2.2J µg/L) at concentrations below its 2L Standard of 6,000 µg/L. SVOCs were not detected above laboratory reporting limits or the 2L Standard in samples GW-02 or GW-03. RCRA Metals As discussed in Section 3.2, the groundwater sample from temporary monitoring well GW-03 had elevated turbidity. Terracon considers the elevated metals concentrations in the sample collected Brownfields Assessment Report Carolina Foundry Brownfields Site ■ Charlotte, NC March 14, 2017 ■ Terracon Project No. 71167563 Responsive ■Resourceful ■Reliable 10 from well GW-03 to be a result of high turbidity rather than actual concentrations representative of the conditions at the site. Various metals were detected in the four (including the duplicate) groundwater samples above the laboratory reporting limits but none of the detected metals exceeded their respective 2L Standard. The following RCRA metals were detected in the groundwater samples: §Aluminum was detected in each of the four groundwater samples. Currently, a 2L Standard for aluminum has not been established. §Barium was detected in each of the four samples at concentrations well below the 2L Standard of 700 µg/L. §Copper was detected in each of the four samples at levels that are well below its 2L Standard of 1,000 µg/L. §Chromium was only detected in sample GW-03 (4.5J µg/L), below its 2L Standard of 10 µg/L. §Lead was only detected in sample GW-03 (2.7J µg/L), below its 2L Standard of 15 µg/L. §Zinc was detected in each of the four samples at concentrations that are well below its 2L Standard of 1,000 µg/L. In addition to comparing VOCs to the 2L Standards and DWM Residential Groundwater Vapor Intrusion Screening Levels, Terracon also used the Brownfields Vapor Intrusion Groundwater Concentration to Indoor Air Concentration (GWC-IAC) Calculator, Version 3.45 to assess the potential vapor intrusion risk due to off-gassing from groundwater. The metals detected in the four groundwater samples collected at the site and diethylphthalate (SVOC) do not readily volatilize and are not included in the list of compounds of the GWC-IAC Calculator. As such, the risk calculations were performed for samples GW-02, GW-03, and DUP-02-011117, the only groundwater samples with detected VOCs. According to the calculator, cumulative carcinogenic risk and the non-carcinogenic hazard quotient for samples GW-02, GW-03, and DUP-02-011117 are below the acceptable threshold value under a residential exposure scenario. The residential risk calculator summary sheets are included in Appendix C. 4.3 Soil Sample Results Nine soil samples (including the two background samples and one blind duplicate) were collected for laboratory analysis at the site (Figure 2). Laboratory results are summarized below by analytical method. Soil sample analytical results are summarized in Table 2 and on Figure 4 and the laboratory analytical reports are included in Appendix B. Detected concentrations were compared to the IHSB Residential and Non-Residential Preliminary Soil Remediation Goals (PSRGs), October 2016 version. Concentrations were also evaluated using the Brownfields Soil Risk Calculators.

Naphthalene was detected in sample S-11 above the laboratory reporting limit but below the residential and non-residential PSRGs. Methylene chloride was detected in samples S-11 through S-16 and the blind duplicate sample at concentrations exceeding the laboratory reporting limit but below the residential and non-residential PSRGs. SVOCs SVOCs were detected in soil samples S-12 and S-15: §Sample S-12, collected southeast of the foundry building, contained 10 PAH constituents at concentrations above laboratory reporting limits. Benzo(a)anthracene (0.172J milligrams per kilogram [mg/kg]), benzo(b)fluoranthene (0.239J mg/kg) and benzo(a)pyrene (0.179J mg/kg) exceeded their respective Residential PSRGs. The remaining SVOCs detected in sample S-12 were below their respective residential PSRGs. §Sample SB-15 contained fluoranthene at a concentration that exceeded the laboratory reporting limit but is below the residential PSRGs. §The following soil samples did not contain SVOCs above laboratory reporting limits: S-11, S-13, S-14, S-16, and DUP-01-011017. RCRA Metals Various metals were detected above laboratory reporting limits in each of the soil samples. The metals are summarized below: §Arsenic was detected in each soil sample at concentrations ranging from 2.9 to 4.6 mg/kg that exceeded either the Residential or Non-Residential PSRG. The concentrations of arsenic detected at the site are consistent with the on-site background samples and are within the range of published naturally occurring metal concentrations for the site area (Geochemical Landscapes of the Conterminous United States — New Map Presentations for 22 Elements, USGS, 2001). §Copper was detected in background soil sample BG-01 at a concentration of 1,270 mg/kg which exceeds the Residential PSRG of 620 mg/kg. Copper concentrations detected in the remaining eight soil samples below the PSRGs. The reason for the presence of elevated copper and other metals detected in background sample BG-01 is unknown at this time. §The remaining metals were detected at concentrations below their respective PSRGs: o Aluminum: 9 of 9 samples (7650 to 15,300 mg/kg); o Barium: 9 of 9 samples (16.7 to 88.0 mg/kg); o Cadmium: 2 of 9 samples (0.069J and 0.74 mg/kg); o Chromium: 9 of 9 samples (23.2 to 45.3 mg/kg); o Lead: 9 of 9 samples (8.5 to 201 mg/kg); Brownfields Assessment Report Carolina Foundry Brownfields Site ■ Charlotte, NC March 14, 2017 ■ Terracon Project No. 71167563 Responsive ■Resourceful ■Reliable 12 o Mercury: 9 of 9 samples (0.011 to 0.12 mg/kg); o Silver: 7 of 9 samples (0.26J to 0.59 mg/kg); and o Zinc: 9 of 9 samples (8.4 to 586 mg/kg). Detected concentrations of VOCs, SVOCs, and metals in soil samples were evaluated using the NC Brownfields Program Soil Risk Calculator. Cumulative carcinogenic risk and the non- carcinogenic hazard quotient for all of the samples are below the unacceptable threshold value under a residential exposure scenario. The residential risk calculator summary sheets for each of the 9 soil samples is included in Appendix C. 4.4 Soil Vapor Sample Results Soil vapor sample results are shown on Figure 6 and summarized on Table 5. The laboratory analytical reports are included in Appendix B. No leaks were detected in the sample manifolds during the initial dead-head or shut-in tests. After purging, the purge tubing was screened for helium and VOCs. VOCs were not detected within the purge tubing for each of the seven soil vapor samples above ambient air PID readings. During purging, helium was detected in six of the seven SV samples (SV-01, SV-02, SV-04, SV-05, SV- 06, and SV-07). Although helium was present in the line, the leaks are considered to be minor, as helium within the line was far less than what was detected within the shroud. Therefore, Terracon does not consider the minor leaks to be a QA/QC concern. Sample SV-07 was also analyzed for helium by the analytical laboratory to obtain a more reliable leak quantification. Based on the laboratory analytical result for sample SV-07 helium (0.37%) was detected above the reporting limit of 0.12%. This corresponds to a 3% leak which is well below the 10% leak threshold specified in the NCDEQ Vapor Intrusion Guidance (2014); therefore, the QA/QC helium sample supports the integrity of the soil vapor sample results. A level 2 QA/QC data package is provided with the soil vapor laboratory results in Appendix B. Laboratory analytical results for the soil vapor samples were compared to the NCDEQ DWM Soil Gas Screening Levels (SGSL) for a residential exposure scenario, updated October 2016. VOCs were not detected above non-residential SGSLs. Only 1,2,4-trimethylbenzene was detected above the residential SGSL in one sample (SV-06). The following compounds were present in soil vapor above laboratory reporting limits: §Acetone (5 samples), benzene (2 samples), 2-butanone (methyl ethyl ketone; 2 samples), carbon disulfide (2 samples), cyclohexane (2 samples), 1,2-dichloropropane (1 sample), ethanol (7 samples), ethyl benzene (2 samples), 4-ethyltoluene (4 samples), Freon 11 (2 samples), heptane (2 samples), hexane (3 samples), 2-hexanone (2 samples), 4-methyl- 2-pentanone (2 samples), 2-propanol (2 samples), propylbenzene (2 samples), styrene (2 samples), toluene (5 samples), 1,2,4-trimethylbenzene (4 samples), 1,3,5- trimethylbenzene (3 samples), m,p-xylene (3 samples), and o-xylene (2 samples). Brownfields Assessment Report Carolina Foundry Brownfields Site ■ Charlotte, NC March 14, 2017 ■ Terracon Project No. 71167563 Responsive ■Resourceful ■Reliable 13 Blind duplicate sample DUP-1-10-17 was collected at location SV-04. The duplicate sample results generally correlate with the primary sample (SV-04) results. Soil vapor sample results were also evaluated using the NC Brownfields Program Sub-Slab or Exterior Soil Gas Concentration to Indoor Air Concentration (SGC-IAC) Calculator, version 3.45. Under a residential exposure scenario, the cumulative vapor intrusion carcinogenic risk and hazard quotient are below the acceptable threshold value for the seven soil vapor samples and the duplicate sample. The risk calculators are included in Appendix C. 5.0 CONCLUSIONS AND RECOMMENDATIONS Based on the scope of services described in this report and subject to the limitations described herein, Terracon provides the following conclusions. Soil §Investigation activities have determined that the upper five feet of soils at the boring locations consist of silty clays and clayey silts. §Overall, environmental impacts in soils appear to be limited. Analytical results of soil samples from previous assessments (S-1 and S-2), and from our assessment (S-12), detected benzo(a)anthracene, benzo(a)pyrene, and benzo(b)fluoranthene) at concentrations above their respective Residential PSRGs. Soil samples S-1 and S-2 by GeoScience also detected ideno(1,2,3-cd)pyrene above its Residential PSRG. Although SVOCs were detected in samples S-1 and S-2 above their respective Residential PSRGs, the Brownfields soil risk calculator did not identify the SVOCs as exceeding the cumulative value for carcinogenic risk or the target hazard quotient for non-carcinogens. §According to the Brownfields soil risk calculator, the cumulative carcinogenic risk and the target quotient for non-carcinogens for the detected constituents (SVOCs, VOCs and metals) in sample S-12 do not exceed the residential carcinogenic risk or the target hazard quotient threshold limit. §Samples collected near the former furnaces inside the foundry building contained various VOCs and SVOCs above their respective Protection of Groundwater PSRGs. According to the Brownfields soil risk calculator, the cumulative carcinogenic risk value and the target hazard quotient are within acceptable risk levels. §Elevated concentrations of copper and other metals were detected in background sample BG-01. Copper exceeded its Residential PSRG. The reason for the presence of elevated copper and other metals detected in background sample BG-01 is unknown at this time. §Although arsenic was detected in each of the soil samples collected from the former foundry building at concentrations that exceed either its Residential or Non-Residential PSRGs, arsenic was also detected above its Non-Residential PSRG in the two background samples. The elevated detected concentrations of arsenic at the site are within the range of published naturally occurring metal concentrations for the site area. Brownfields Assessment Report Carolina Foundry Brownfields Site ■ Charlotte, NC March 14, 2017 ■ Terracon Project No. 71167563 Responsive ■Resourceful ■Reliable 14 Groundwater §Depth to groundwater at the site ranged between 7.08 and 13.19 feet bgs and the groundwater flow direction is generally towards the northeast. §Although VOCs, SVOCs, and metals were detected in the groundwater, none of the detected constituents exceeded the 2L Standards. §The Brownfields GWC-IAC Calculator confirms that under a residential-use scenario, off- gassing from groundwater at the site does not represent a vapor intrusion concern. §Groundwater will not be used for any purpose at the site, and it is not anticipated that groundwater will be encountered during redevelopment activities. Soil Vapor §Soil vapor sample SV-06 collected from the former Carolina Foundry contained 1,2,4- trimethylbenzene above its Residential SGSL. The remaining soil vapor samples collected at the former foundry did not detect VOCs above the SGSLs. Cumulative risk evaluations using the Brownfields Program SGC-IAC Calculator confirm vapor intrusion risks are acceptable under a residential scenario. §Soil vapor sample results do not indicate vapor intrusion problems at the site; therefore, vapor mitigation is not required based on soil vapor sample results.

The laboratory performed analysis via EPA Method TO-15 using GC/MS in the full scan mode. This workorder was independently validated prior to submittal using 'USEPA National Functional Guidelines' as generally applied to the analysis of volatile organic compounds in air. A rules-based, logic driven, independent validation engine was employed to assess completeness, evaluate pass/fail of relevant project quality control requirements and verification of all quantified amounts. There were no receiving discrepancies. Receiving Notes The workorder was reissued on 4/3/17 for the following reasons: 1)To report estimated values for target compound hits that are below the reporting limit but greater than the method detection limit. Concentrations that are below the level at which the canister was certified (0.2 ppbv for compounds reported at 0.5 ppbv and 0.8 ppbv for compounds reported at 2.0 ppbv) may be false positives. 2)To report the data using a different format. Analytical Notes Eight qualifiers may have been used on the data analysis sheets and indicates as follows: B - Compound present in laboratory blank greater than reporting limit (background subtraction not performed). J - Estimated value. E - Exceeds instrument calibration range. S - Saturated peak. Q - Exceeds quality control limits. U - Compound analyzed for but not detected above the reporting limit, LOD, or MDL value. See data page for project specific U-flag definition. UJ- Non-detected compound associated with low bias in the CCV N - The identification is based on presumptive evidence. File extensions may have been used on the data analysis sheets and indicates as follows: a-File was requantified b-File was quantified by a second column and detector r1-File was requantified for the purpose of reissue Definition of Data Qualifying Flags Page 3 of 51 Dilution Factor: Instrument/Filename: 1/16/17 09:24 PM 2.52 msdp.i / p011617R1 EPA METHOD TO-15 GC/MS FULL SCAN 1701155AR1-01A 1/10/17 06:12 PM 1 Liter Summa Canister Carolina Foundry SV-01 Date/Time Analyzed: Client ID: Lab ID: Date/Time Collected: Media: (ug/m3)CAS# LOD Compound (ug/m3) MDL Rpt.

The laboratory performed analysis via Modified ASTM Method D-1946 for Helium in air using GC/TCD. The method involves direct injection of 1.0 mL of sample. Method modifications taken to run these samples are summarized in the table below. Specific project requirements may over-ride the ATL modifications. Requirement ATL ModificationsASTM D-1946 Calibration A single point calibration is performed using a reference standard closely matching the composition of the unknown. A minimum of 5-point calibration curve is performed. Quantitation is based on average Response Factor. Reference Standard The composition of any reference standard must be known to within 0.01 mol % for any component. The standards used by ATL are blended to a >/= 95% accuracy. Sample Injection Volume Components whose concentrations are in excess of 5 % should not be analyzed by using sample volumes greater than 0.5 mL. The sample container is connected directly to a fixed volume sample loop of 1.0 mL on the GC. Linear range is defined by the calibration curve. Bags are loaded by vacuum. Normalization Normalize the mole percent values by multiplying each value by 100 and dividing by the sum of the original values. The sum of the original values should not differ from 100% by more than 1.0%. Results are not normalized. The sum of the reported values can differ from 100% by as much as 15%, either due to analytical variability or an unusual sample matrix. Precision Precision requirements established at each concentration level. Duplicates should agree within 25% RPD for detections > 5 X's the RL. Receiving Notes There were no receiving discrepancies. There were no analytical discrepancies. Analytical Notes Page 3 of 8 Per client request, the workorder was reissued on 4/3/2017 to report estimated values for target compound hits that are below the reporting limit but greater than the method detection limit.
