According to the Mecklenburg County Online Geographic Information Systems website, the subject property is identified as Parcel Identification Number (PIN) 15904612 and was owned by Clariant Corporation (Demerger)/Alisa Bradshaw. The approximately 9.799-acre subject property was developed with Clariant Corporation, a specialty chemical company. The subject property is developed with an approximate 92,780-square foot building that is subdivided into Buildings 1-4 that were reportedly constructed in 1956; an approximate 75,606-square foot building designated as Building 5 that was reportedly constructed in 1956; an approximately 391-square foot building designated as Building 6 that was reportedly constructed in 1994; and an approximate 100-aquare foot structure designated as Building 7. ECS previously completed a Phase I Environmental Site Assessment (ESA) on the property for Parkside Partners/4000 Monroe, LLC, as documented in the report dated January 15, 2021, ECS Project Number 49:12929. The ESA identified the following recognized environmental conditions (RECs): • Based on a history of industrial and fueling operations of this facility, the use of chemicals, and the potential for an undocumented release that could impact the subject property, ECS considered the historic and current use of the site to represent a REC. • ECS considered the potential for a release from the wastewater treatment activities in Building 6 which was constructed in 1996 and associated piping to represent a REC. • Based on the lack of closure documentation and the potential for an undocumented release at the subject property to impact subsurface conditions, ECS considered four former 4,000-gallon gasoline underground storage tanks (USTs) to represent a REC. • ECS considered the potential for additional orphan USTs associated with the former gasoline station on the northwestern portion of the property that operated from around 1962 to 1993 to represent a REC. • Based on distance, measured groundwater flow towards the subject property, and documented impacts to groundwater above regulatory standards, ECS considered the incident associated with the former gasoline station that operated on the northeast adjoining property from around 1983- 2005 to represent a REC. • Based on measured groundwater flow towards the subject property and documented impacts to groundwater in close proximity to the subject property, ECS considered the potential for chlorinated solvents to have migrated from the east adjoining Takatori facility to represent a REC. • ECS considers the documented tetrachloroethene (PCE) impacts in groundwater above regulatory standards during a Phase II ESA at the north adjacent property in 2019 to represent a REC. • Based on length of service from approximately 1969 to 1994 and the potential for an undocumented release that could impact the subject property, ECS considers the former operation of the north adjacent dry-cleaning facility to represent a REC. In an effort to determine if the subject property had been adversely affected by the identified RECs, ECS conducted an initial limited environmental assessment at the site as detailed in ECS’s Report of Environmental Assessment Services (ECS Project No.: 49:12929-A, submitted March 12, 2021). This initial limited environmental assessment included the following: 2 Brownfields Assessment Report & Receptor Survey Clariant Corporation Site Brownfields Project Number 25036-21-060 ECS Project No. 49:12929-D May 17, 2022 • ECS observed the performance of a ground penetrating radar (GPR) survey of the area where a former gasoline station and three 550-gallon underground storage tanks (USTs) were located in the northwest corner of the subject property. The results of the GPR survey did not indicate the presence of any remaining USTs in this area. • 17 borings (GW-1 through GW-17) were advanced at the site at the locations shown on Figure 2 for the collection of groundwater samples. Refusal was encountered in borings GW-11 (18 feet below ground surface or ft-bgs) and GW-15 (12 ft-bgs) prior to encountering groundwater. Groundwater samples were collected from the remaining borings. Review of the laboratory analytical results for the groundwater samples collected indicated one or more volatile organic compounds (VOCs) in the samples collected from borings GW-1, GW-2, GW-4 through GW-7, GW- 12, GW-13, GW-16, and GW-17 at concentrations greater than the laboratory method detection limits. Benzene in the sample collected from GW-13, methyl tert-butyl ether in the samples collected from GW-12 and GW-13, and tetrachloroethene (also known as perchloroethene or PCE) in the samples collected from GW-1, GW-2, GW-5, GW-13, GW-16, and GW-17 were detected at concentrations greater than the North Carolina 2L Groundwater Quality Standards (NC2LGWQS). In addition, the concentrations of benzene in the sample collected from GW-13 and PCE in the samples collected from GW-2, GW-5, GW-13, and GW-17 were detected greater than the NCDEQ Non-Residential Groundwater Vapor Intrusion Screening Level (VISL). Based on the anticipated groundwater flow direction and the compound concentrations detected in the groundwater samples collected, it appears the groundwater impacts may have originated from off-site sources. • 12 sub-slab soil gas sample points (SG-A through SG-K) were installed beneath the interior of the structures on the subject site. The approximate locations of these soil gas samples are shown on Figure 3. Review of the laboratory analytical results for the samples collected from the sub-slab sample points indicated several VOCs at concentrations greater than the laboratory method detection limits in each of the sub-slab samples collected as part of this investigation. The concentration of chloroform detected in the SG-A sample was present greater than its NCDEQ Non-Residential Sub-Slab and Exterior Soil Gas VISL. Chloroform is present in municipally supplied water and is often detected due to leaks in municipal water lines. As chloroform was detected at a concentration greater than its VISL in the SG-A sample and more than five compounds with non- cancer effects were detected at concentrations greater than the laboratory method reporting limits in each of the sub-slab soil gas samples collected as part of this investigation, ECS input the laboratory analytical results of each sub-slab soil gas sample collected in to the NCDEQ Risk Calculator. Based on the results of the NCDEQ Risk Calculator, the concentrations in the sub-slab soil gas samples did not exceed the risk thresholds. Based upon the results above, Parkside Partners/4000 Monroe, LLC requested additional assessment activities. ECS prepared a proposal (ECS Proposal No.: 49:23603P, approved April 8, 2021) for the collection of soil samples, additional groundwater samples, and additional sub-slab soil gas samples. In addition, ECS was requested to include the collection of groundwater elevation data for the estimation of groundwater flow direction beneath the site. ECS submitted the Report of Additional Environmental Assessment Services (ECS Project No. 49:12929-B) on May 6, 2021, documenting the additional assessment services. This additional environmental assessment included the following: 3 Brownfields Assessment Report & Receptor Survey Clariant Corporation Site Brownfields Project Number 25036-21-060 ECS Project No. 49:12929-D May 17, 2022 • Eight soil borings (B-1 through B-4, SB-1A, SB-2A, SB-13A, and SB-18) were advanced at the site for the collection of soil samples for laboratory analysis. The locations of the soil borings are indicated on Figure 4. Review of the laboratory analytical results for the soil samples collected did not indicate compounds at concentrations greater than the laboratory method reporting limits in any of the soil samples collected at the site. • Three temporary monitoring wells (GW-5A, GW-16A, and GW-17A) were installed along the northern property boundary to further assess site groundwater. In addition, between May 10 and 11, 2021, temporary monitoring wells GW-1A, GW-2A, GW-13A, and GW-18 were installed in soil borings SB-1A, SB-2A, SB-13A, and SB-18, respectively. The locations of the temporary monitoring wells are shown on Figure 2. Review of the laboratory analytical results for the groundwater samples collected indicated concentrations of PCE in the GW-1A, GW-2A, GW-13A, GW-17A, and GW-18 samples at concentrations greater than its NC2LGWQS, including the concentrations in the GW-13A and GW-17A samples which were greater than its Non-Residential Groundwater VISL. Groundwater sampling points GW-13A and GW- 17A were located along the eastern and northeastern property boundaries, respectively, of the site. The PCE concentrations detected in groundwater decreased in the samples collected from the eastern and northeastern property boundaries toward the interior of the site. In addition, 2-butanone (GW-1A and GW-2A samples), chloroform (GW-17A sample), chloromethane (GW-13A), and methyl tert-butyl ether (GW-13A and GW-17A) were detected at concentrations greater than the laboratory method reporting limits, but less than their respective NC2LGWQS and Non-Residential Groundwater VISL. • Six sub-slab soil gas sample points (SG-L through SG-Q) were installed in the interior of the structures of the subject site. The approximate locations of these soil gas samples are shown on Figure 3. Review of the laboratory analytical results for the samples collected from the sub-slab sample points indicated several VOCs at concentrations greater than the laboratory method detection limits in each of the sub-slab samples collected as part of this investigation. Only the concentrations of chloroform detected in the SG-L sample and PCE in SG-O sample were present greater than their respective NCDEQ Non-Residential Sub-Slab and Exterior Soil Gas VISLs in the sub-slab samples collected as part of this assessment. In light of the sub-slab vapor results, ECS input the laboratory analytical results of each sub-slab soil gas sample collected in to the NCDEQ Risk Calculator. Based on the results of the NCDEQ Risk Calculator, the concentrations in the sub- slab soil gas samples did not exceed the risk thresholds for nonresidential use. Based on the environmental assessment data collected and the planned redevelopment of the site, a Brownfields Property Application (BPA) was submitted to the NCDEQ, on April 28, 2021, along with the above referenced assessment services reports. On September 10, 2021, the NCDEQ Brownfields Program submitted a Letter of Eligibility and established the Brownfields Project Number as 25036-21-060. On September 30, 2021, the property was purchased by 4000 Monroe LLC c/o Parkside Partners. On November 4, 2021, ECS presented a Brownfields Kickoff Meeting that summarized the site, previous assessment activities and results, was well as the proposed site redevelopment activities during a Teams meeting on, with Parkside Partners, their environmental attorney, and the assigned NCDEQ Brownfields Project Manager (Mr. Peter Doorn). As a result of the kickoff meeting, in a January 6, 2022, email, Mr. Doorn requested for additional assessment activities to address potential data gaps, as identified by the NCDEQ, and requested the status of a previously documented monitoring well that was reportedly located near the southeast property corner. Generally, the additional assessment activities included the 4 Brownfields Assessment Report & Receptor Survey Clariant Corporation Site Brownfields Project Number 25036-21-060 ECS Project No. 49:12929-D May 17, 2022 collection and laboratory analysis of additional soil, sub-slab soil gas, and indoor air, as well as completing a Brownfields receptor survey. Based upon the January 6, 2022, email from the NCDEQ Brownfields Project Manager, ECS prepared a Work Plan (ECS Project No. 49:12929-C) and submitted to NCDEQ Brownfields on February 1, 2022. The Work Plan was approved by NCDEQ Brownfields via email on February 2, 2022. 2.0 PREVIOUS INVESTIGATIONS ECS previously conducted multiple environmental assessments at the site. Previous assessment activities conducted on the various parcels include the following: • Phase I ESA, prepared by ECS and dated January 15, 2021 (ECS Project No.: 49:12929). • Report of Environmental Assessment Services by ECS and dated March 12, 2021 (ECS Project No.: 49:12929-A. The assessment activities are described above in Section 1.0. • Report of Additional Environmental Assessment Services by ECS and dated May 26, 2021 (ECS Project No.: 49:12929-B. The assessment activities are described above in Section 1.0. 3.0 OBJECTIVE OF THE ASSESSMENT The objective of the assessment was to address the data gaps identified by the BF Program in their January 6, 2022, email by conducting the following sampling activities: • Conduct a reconnaissance of the southeastern portion of the subject property in an effort to evaluate if a monitoring well reported to be that area from an offsite investigation, remained. • The advancement of three soil borings to depths of up to two feet bgs and collection of a soil sample from each boring. • The collection of seven additional indoor air samples. • The collection of seven additional sub-slab soil gas samples. • Completion of a Brownfields Receptor Survey. The indoor air and sub-slab soil gas samples collected were submitted for laboratory analysis of VOCs by EPA Method TO-15. The soil samples collected were submitted for laboratory analysis of VOCs by EPA Method 8260, semi- volatile organic compounds (SVOCs) by EPA Method 8270, RCRA Metals by EPA Method 6010/7471, and hexavalent chromium by EPA Method 7199 and were selected from the interval exhibiting the highest photoionization detector (PID) reading in each boring. The sampling activities were conducted in general accordance with the Brownfields Assessment Work Plan (Work Plan) prepared by ECS (ECS Project No. 49:12929-C) dated February 1, 2022, and approved by the NCDEQ Brownfields Program via email on February 2, 2022. This assessment was also conducted in general accordance with the North Carolina Division of Waste Management’s (NCDWM) Inactive Hazardous Site Program’s Guidelines for Assessment and Cleanup (Revised October 2015). 5 Brownfields Assessment Report & Receptor Survey Clariant Corporation Site Brownfields Project Number 25036-21-060 ECS Project No. 49:12929-D May 17, 2022 4.0 FIELD ACTIVITIES 4.1 Utility Locate Prior to commencing with field activities, ECS contacted North Carolina One-Call 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. In addition, ECS contracted with Priority Underground Locating Services to clear the boring areas of private utilities. 4.2 Monitoring Well Evaluation On February 25, 2022, ECS personnel conducted a reconnaissance of the southeastern portion of the site in an effort to try to locate a monitoring well that was reportedly in this area. The area is indicated on Figure 2. This monitoring well was previously identified as ZMW-1 and was associated with the Former Rea Construction East Plant site (NCDEQ Groundwater Incident #12783), which was located offsite to the southeast. 4.3 Soil Samples Number and Sample Location In general accordance with the Work Plan, ECS advanced three soil borings via decontaminated hand auger at three locations (SB-1, SB-2, and SB-3) to depths of up to two feet bgs at the locations shown on Figure 4. Sample Collection On February 25, 2022, ECS collected two aliquots from each boring. Each aliquot was placed in a re- sealable plastic bag which was promptly sealed after soil was placed within. ECS used a PID to screen for volatile organic vapors in one of the aliquots associated with each boring. One soil sample from borings SB-1 through SB-3 were collected over the zero to two feet bgs interval. Copies of the field sampling notes are included in Appendix A. Sample Analysis Following sample collection, the sample containers were placed on ice in a cooler and maintained under chain-of-custody until delivered to Pace Analytical Services, LLC (Pace), a North Carolina certified laboratory located in Huntersville, North Carolina. Chain-of-custody protocol was utilized throughout the collection and transport of the samples. As previously stated, the soil samples collected were submitted for laboratory analysis of VOCs by EPA Method 8260, SVOCs by EPA Method 8270, RCRA Metals by EPA Method 6010/7471, and hexavalent chromium by EPA Method 7199. The laboratory reporting limits were reported at or below the applicable NCDEQ Preliminary Soil Remediation Goals (PSRGs) for residential soil, industrial/commercial soil, and protection of groundwater. Additionally, concentrations detected below the laboratory reporting limit (RL) and above the laboratory method detection limit were reported by the laboratory were flagged with a J-flag qualifier, indicating the reported concentrations were estimates. For quality assurance/quality control (QA/QC) purposes, one duplicate soil sample (DUP-1) was collected 6 Brownfields Assessment Report & Receptor Survey Clariant Corporation Site Brownfields Project Number 25036-21-060 ECS Project No. 49:12929-D May 17, 2022 from the same location as SB-1 and analyzed for the same compounds as the record sample. 4.4 Indoor Air Samples Number and Sample Location In general accordance with the approved Work Plan, ECS collected seven indoor air samples at the approximate locations shown on Figure 5. The indoor air samples were identified as IA-1 through IA-7. Sample Collection On April 19, 2022, the samples were collected using an individually certified 6-liter (L) Summa canister equipped with an 8-hour flow restrictor. The samples were collected by placing the intake for the Summa canister at a height of approximately 5 feet above the floor during sampling. Copies of the field sampling notes are included in Appendix A. ECS checked and noted the vacuum on each Summa Canister before initiating the sampling procedure. The sampling procedure was terminated when the vacuum reading was approximately five inches of mercury. Sample Analysis Following sample collection, the sample containers were repackaged and delivered to Con-Test Analytical Laboratory (Con-Test), an analytical laboratory located in East Longmeadow, Massachusetts. Chain-of- custody protocol was utilized throughout the collection and transport of the samples. As previously stated, the indoor air samples collected were submitted for laboratory analysis of VOCs by EPA Method TO-15. The laboratory reporting limits were reported at or below the applicable North Carolina Residential and Non-Residential VISLs. Additionally, concentrations detected below the laboratory reporting limit (RL) and above the laboratory method detection limit were reported by the laboratory were flagged with a J- flag qualifier, indicating the reported concentrations were estimates. Initially, for QA/QC purposes, one duplicate indoor air sample and one ambient, outdoor air sample were to be collected as part of the indoor air sampling assessment; however, these samples were not collected. The absence of these samples does not appear to have jeopardized the findings. 4.5 Sub-Slab Soil Gas Samples Number and Sample Location In accordance with the approved Work Plan, ECS collected seven sub-slab soil gas samples (SS-1 through SS-7) at the approximate locations shown on Figure 3. The sub-slab soil gas samples were collected adjacent to, but after, the collection of the above referenced indoor air samples. 7 Brownfields Assessment Report & Receptor Survey Clariant Corporation Site Brownfields Project Number 25036-21-060 ECS Project No. 49:12929-D May 17, 2022 Sample Collection The sub-slab soil gas samples were collected using VaporPins® within the existing floor slab. On April 20, 2022, ECS installed VaporPins® using a hammer drill to penetrate through the concrete slab. Once the concrete slab was penetrated, a new VaporPin® with a new silicon sleeve was inserted in the concrete slab in general conformance with manufacturer’s recommendations (Vapor Pin Enterprises, Inc.). The VaporPin® setup was allowed to equilibrate for at least 20 minutes prior to leak testing. Prior to collecting the sub-slab soil gas samples, laboratory grade helium gas was used as a QA/QC measure to confirm the integrity of the probe seal at each sample location. A shroud that encloses the fittings and sample train was placed over each newly installed vapor point and filled with helium. The sample tubing and tracer gas tubing was placed through the shroud wall via rubber grommets. During the purging stage, the cylinder was flooded with laboratory grade helium via the hose placed through the shroud wall. A Model MGD-2002 Multi-Gas Leak detector was connected to the probe tube and the air stream being purged was measured for helium. A helium concentration of less than ten percent helium detected within the shroud was considered acceptable. During leak check activities, helium concentrations remained above 10 percent in air by volume in each shroud and below 10 percent of the concentration of Helium inside of the shroud in each sample train. In addition to the leak check, a shut- in test was conducted to assess for leaks in the fittings and regulator. Copies of the field sampling notes are included in Appendix A. Following purging, the vapor point was connected to a batch certified 1-liter Summa canister, which was used to collect the sample. The Summa canister was fitted with a five-minute flow regulator. ECS checked and noted the vacuum on each Summa Canister before initiating the sampling procedure. The sampling procedure was terminated when the vacuum reading was approximately five inches of mercury. Sample Analysis Following sample collection, the sample containers were repackaged and delivered to Con-Test. Chain-of- custody protocol was utilized throughout the collection and transport of the samples. As previously stated, the soil samples collected were submitted for laboratory analysis of VOCs by EPA Method TO-15. The laboratory reporting limits were reported at or below the applicable North Carolina Residential and Non-Residential VISLs. Additionally, concentrations detected below the laboratory reporting limit (RL) and above the laboratory method detection limit were reported by the laboratory were flagged with a J-flag qualifier, indicating the reported concentrations were estimates. For QA/QC purposes, one duplicate soil sample (DUP) was collected from the same location as SS-1 and analyzed for the same compounds as the record sample. 5.0 RESULTS 5.1 Monitoring Well Evaluation Results As stated previously, ECS personnel examined the area shown on Figure 2 for the presence of the reported monitoring well ZMW-1. No evidence of the monitoring well was noted by ECS. Based upon records reviewed by ECS, monitoring well ZMW-1 was last sampled in August of 2003, with no analyzed compounds being reported at concentrations greater than the laboratory method reporting limits. 8 Brownfields Assessment Report & Receptor Survey Clariant Corporation Site Brownfields Project Number 25036-21-060 ECS Project No. 49:12929-D May 17, 2022 5.2 Soil Boring Soil Analysis Constituents of concern were not detected in any soil samples at concentrations greater than the industrial/commercial PSRGS. PCE was detected in the SB-2 soil sample at an estimated concentration greater than its Protection of Groundwater PSRG, but less than its Residential and Industrial/Commercial PSRGs. Four SVOCs were detected in the SB-2 soil sample at estimated concentrations greater than the laboratory method detection limits, but less than their respective PSRGs. Additional VOCs and SVOCs were not detected at concentrations greater than the laboratory method reporting limits in any of the samples collected. Arsenic in the SB-3 soil sample and hexavalent chromium in the SB-1, SB-2, and SB-3 soil samples were detected at concentrations greater than its Residential PSRGs, but less than its Protection of Groundwater and Industrial/Commercial PSRGs. Additional metals were detected in each of the samples collected at concentrations greater than the laboratory method reporting limits, but less than their respective PSRGs. A summary of the soil sample analytical results is included as Table 1 and the laboratory report is included as Appendix B. Quality Control Laboratory results of duplicate soil sample (DUP-1) that was collected as a duplicate of soil sample SB-1 and analyzed for VOCs, SVOCs, and RCRA metals plus hexavalent chromium using EPA Method 8260, 8270, 6020/7471, and 7199 were similar to those detected in SB-1. A Level II QA/QC package was requested from the laboratory. The results are summarized in Table 1 and the laboratory report is included as Appendix B. 5.3 Indoor Air Analysis Review of the laboratory analytical results for the indoor air samples indicated concentrations of seven compounds in one or more of the IA-1, IA-2, IA-4, IA-5, IA-6, and IA-7 indoor air samples greater than their respective Residential VISL; with concentrations of 1,4-dichlorobenzene in the IA-2 indoor air sample, and ethyl acetate in the IA-5, IA-6, and IA-7 indoor air samples detected at concentrations greater than their respective Non-Residential VISLs. In light of the indoor air sample results, ECS input the laboratory analytical results of the indoor air samples in to the NCDEQ Risk Calculator. Based on the results of the NCDEQ Risk Calculator, the concentrations in the IA-1 through IA-4 indoor air samples did not exceed the risk thresholds. However, the concentrations in the IA-5, IA-6, IA-7 indoor air samples did exceed the risk threshold for Residential classification, with the concentrations in the IA-5 and IA-6 indoor air samples also exceeding the risk thresholds for the Non- Resident Worker classification. These exceedances are likely attributable to the use of ethyl acetate in the current laboratory operations as opposed to a subsurface release (See Appendix C for Safety Data Sheets (SDSs) documenting the onsite use of ethyl acetate). If the ethyl acetate results are removed from the from the risk calculators, the results of the IA-5 and IA-6 indoor air samples do not exceed the risk thresholds for Resident or Non-Residential Works classifications. Output from the results of the NCDEQ Risk Calculator are presented in Appendix D. 9 Brownfields Assessment Report & Receptor Survey Clariant Corporation Site Brownfields Project Number 25036-21-060 ECS Project No. 49:12929-D May 17, 2022 Additional compounds were detected in each sample collected at concentrations greater than the laboratory method detection limit, but less than their respective VISLs. A summary of the indoor air sample analytical results is included as Table 2 and the laboratory report is included as Appendix B. 5.4 Sub-Slab Soil Gas Soil Analysis Review of the laboratory analytical results for the sub-slab soil gas samples indicated concentrations of chloroform in the SS-1 sub-slab soil gas sample, dichlorofluoromethane in the SS-7 sub-slab soil gas sample, and PCE in the SS-1, SS-5, SS-6, and SS-7 sub-slab soil gas samples at concentrations greater than their respective Residential VISLs, but less than their respective Non-Residential VISLs. Additional compounds were detected in each of the sub-slab soil gas samples collected at concentrations greater than the laboratory method detection limits, but less than their respective Residential and Non- Residential VISLs In light of the sub-slab soil gas sample results, ECS input the laboratory analytical results of the sub-slab soil gas samples in to the NCDEQ Risk Calculator. Based on the results of the NCDEQ Risk Calculator, the concentrations in each of the sub-slab soil gas samples did not exceed the Residential or Non-Residential risk thresholds. Output from the results of the NCDEQ Risk Calculator are presented in Appendix D. A summary of the sub-slab soil gas sample analytical results is included as Table 3 and the laboratory report is included as Appendix B. Quality Control One duplicate sub-slab soil gas sample (DUP) was collected as a duplicate of sub-slab soil gas sample SS-1 and analyzed for VOCs using EPA Method TO-15. The compounds detected in the duplicate sample were similar to those detected in SS-1. A Level II QA/QC package was requested from the laboratory. The results are summarized in Table 3 and the laboratory report is included as Appendix B. 5.5 Brownfields Receptor Survey ECS performed a Brownfields Receptor Survey. The results of the Brownfields Receptor Survey identified an inactive water supply well located approximately 1,000 feet to the north of the subject site located at 640 Vinewood Place. The nearest residence to the subject site is located approximately 525 feet northwest at 613 Mayview Drive. A property with a basement was identified approximately 890 feet northwest of the subject property at 645 Mayview Drive. Underground utilities were noted in the vicinity of the site at the locations identified on the figure included in Appendix E. Also, the Brownfields Receptor Survey form is included in Appendix E. 5.6 Investigative Derived Waste In accordance with the approved Work Plan, Investigative Derived Waste (IDW) generated from the soil borings (i.e., soil cuttings) were thinly spread onsite in the vicinity of the boring location. IDW generated 10 Brownfields Assessment Report & Receptor Survey Clariant Corporation Site Brownfields Project Number 25036-21-060 ECS Project No. 49:12929-D May 17, 2022 during the installation and sampling of the monitoring wells (i.e., soil cuttings, development water, and purge water) was placed onsite in the vicinity of the monitoring well location. 6.0 CONCLUSIONS AND DISCUSSION Based on the results of the sampling presented above, as well as the receptor survey conducted for the site, ECS has the following conclusions: • Based on the results of the Brownfields Receptor Survey, an inactive water supply well located approximately 1,000 feet to the north of the subject site located at 640 Vinewood Place. The nearest residence to the subject site is located approximately 525 feet northwest at 613 Mayview Drive. A property with a basement was identified approximately 890 feet northwest of the subject property at 645 Mayview Drive. Also, the Brownfields Receptor Survey form is included in Appendix E. • The monitoring well ZMW-1 was not located during ECS’ reconnaissance of the reported location of the monitoring well. Therefore, it is estimated that this well was abandoned. • Constituents of concern were not detected at concentrations greater than the Industrial/Commercial PSRGS in any of the soil samples collected as part of this assessment. • Seven compounds in one or more of the IA-1, IA-2, IA-4, IA-5, IA-6, and IA-7 indoor air samples were detected at concentrations greater than their respective Residential VISLs, but less than their respective Non-Residential VISLs. Concentrations of 1,4-dichlorobenzene in the IA-2 indoor air sample, and ethyl acetate in the IA-5, IA-6, and IA-7 indoor air samples were detected at concentrations greater than their respective Non-Residential VISLs. As noted below, the primary constituents of concern, PCE and trichloroethene (TCE), were not detected at concentrations greater than the Residential VISLs. • The results of the NCDEQ Risk Calculator for the indoor air samples indicated the concentrations in the IA-5, IA-6, and IA-7 indoor air samples did exceed the risk threshold for Residential classification, with the concentrations in the IA-5 and IA-6 indoor air samples also exceeding the risk thresholds for the Non-Resident Worker classification. • ECS removed the ethyl acetate concentrations from the calculators of the IA-5 and IA-6 indoor air samples because ethyl acetate is documented to be used in the buildings within which the samples were collected. The results of the new calculations did not indicate exceedances of either the Residential or Non-Residential Worker risk thresholds for the IA-5 and IA-6 indoor air samples. Output from the results of the NCDEQ Risk Calculator are presented in Appendix D. • Ethyl acetate is used in paints as an activator or hardener. A small laboratory used to study paint products is located in the general areas from which indoor air samples IA-5 and IA-6 were collected. Based upon Safety Data Sheets (SDSs) obtained from Clariant Corporation/Colorant Solutions, ethyl acetate is used in the laboratory activities. The SDSs are included in Appendix C. • The locations of indoor air samples IA-5, IA-6, and IA-7 and sub-slab soil gas samples SS-5, SS-6, and SS-7 overlain on floor plans of the first floor of Buildings 2, 3, and 4 are included in Appendix F. The laboratory is located on the first floor of Building 3, with office space associated with the laboratory located on the second floor of Building 3. Buildings 2 and 4 are currently vacant. The laboratory is scheduled to vacate the site on September 10, 2022. • Review of the laboratory analytical results for the sub-slab soil gas samples indicated concentrations of chloroform in the SS-1 sub-slab soil gas sample, dichlorofluoromethane in the 11 Brownfields Assessment Report & Receptor Survey Clariant Corporation Site Brownfields Project Number 25036-21-060 ECS Project No. 49:12929-D May 17, 2022 SS-7 sub-slab soil gas sample, and PCE in the SS-1, SS-5, SS-6, and SS-7 sub-slab soil gas samples at concentrations greater than their respective Residential VISLs, but less than their respective Non-Residential VISLs. • The results of the NCDEQ Risk Calculator for the sub-slab soil gas samples indicated the concentrations in each of the sub-slab soil gas samples did not exceed the risk thresholds for Residential and Non-Residential Worker classifications. • PCE and TCE, the constituents of concern, were not detected in the sub-slab soil gas samples at concentrations greater than their respective Non-Residential VISLs. Additionally, detected levels of PCE and TCE were less than their respective Residential VISLs. • Based on the samples collected, the results of the indoor samples IA-5, IA-6, and IA-7 are the only samples that exceed the proposed future site use (i.e., commercial, office, etc.). However, the exceedances of the three indoor air samples appear to be due to the use of VOCs by the existing site laboratory, particularly the use of ethyl acetate, and not the result of indoor air intrusion from site soils and/or groundwater. This is supported by the facts that (i) the current laboratory operations use ethyl acetate and (ii) the detected sub-slab soil gas concentrations of ethyl acetate were either below the laboratory method reporting limit or significantly lower than the ethyl acetate concentrations detected in the indoor air samples. • Currently the lab is scheduled to cease operation (September 10, 2022) prior to the anticipated occupancy by future tenants (in approximately March 2023), with demolition of portions of the existing structure scheduled to begin in mid-November 2022. The scheduled demolition of the structure, along with the extended time period after laboratory use and future occupancy, is expected to allow for the current indoor VOCs to dissipate prior to occupancy of the new tenants. 7.0 DEVIATIONS FROM WORK PLAN There were no deviations from the approved Work Plan with the exception of a duplicate indoor air sample was not collected and an ambient background air sample was not collected concurrently with the indoor air samples. Based on a review of the indoor air sample results verses the results of the other site samples, specifically the sub-slab soil gas results, the exclusion of these two samples do not appear to have jeopardized the conclusions presented in this report.

Data qualifiers are applied to note exceptions. Noncompliant quality control (QC) is further explained in narrative comments. · QC results that exceed the upper limits and are associated with non-detect samples are qualified but further narration is not required since the bias is high and does not change a non-detect result. Further narration is also not required with QC blank detection when the associated sample concentration is non-detect or more than ten times the level in the blank. · Matrix QC may not be reported if insufficient sample or site-specific QC samples were not submitted. In these situations, to demonstrate precision and accuracy at a batch level, a LCS/LCSD is performed, unless otherwise specified in the method. · Surrogate and/or isotope dilution analyte recoveries (if applicable) which are outside of the QC window are confirmed unless attributed to a dilution or otherwise noted in the narrative. Regulated compliance samples (e.g. SDWA, NPDES) must comply with the associated agency requirements/permits. Measurement uncertainty values, as applicable, are available upon request. Test results relate only to the sample tested. Clients should be aware that a critical step in a chemical or microbiological analysis is the collection of the sample. Unless the sample analyzed is truly representative of the bulk of material involved, the test results will be meaningless. If you have questions regarding the proper techniques of collecting samples, please contact us. We cannot be held responsible for sample integrity, however, unless sampling has been performed by a member of our staff. Times are local to the area of activity. Parameters listed in the 40 CFR Part 136 Table II as "analyze immediately" and tested in the laboratory are not performed within 15 minutes of collection.

Wash contaminated clothing before reuse. If irritation persists, get medical attention. In case of eye contact : Thoroughly flush the eyes with large amounts of clean low- pressure water for at least 15 minutes, occasionally lifting the upper and lower eyelids. If irritation persists, seek medical attention. Remove contact lenses. Do not use eye ointment unless directed to by a physician. If swallowed : Do not induce vomiting. Risk of damage to lungs exceeds poisoning risk. Drink plenty of water. If vomiting does occur, have victim lean forward to reduce risk of aspiration. If victim is drowsy or unconscious, place on the left side with head down. Never give anything by mouth to an unconscious person. Obtain emergency room treatment immediately. Notes to physician Symptoms : Ingestion of the liquid or exposure to high airborne SAFETY DATA SHEET SDA3C/200PF/IPA/140500 Gen.

Repeated or prolonged contact with skin may cause defatting and drying of the skin which may result in dermatitis. Hazards : May be harmful if swallowed and enters airways. Causes serious eye irritation. May cause respiratory irritation. May cause drowsiness or dizziness. Treatment : Treat symptomatically. Treatment of overexposure should be directed at the control of symptoms and the clinical condition of the patient. There is no specific antidote. Gastric lavage can be used if done shortly after ingestion. GI decontamination with charcoal is not effective unless other toxic co-ingestants are involved. 5. FIRE-FIGHTING MEASURES Suitable extinguishing media : SMALL FIRE: Use dry chemicals, CO2, water spray or alcohol- resistant foam LARGE FIRE: Use water spray, water fog or alcohol-resistant foam Specific hazards during fire fighting : Extremely flammable well below ambient temperatures. Vapor forms explosive mixture with air and may cause a flash fire. Eliminate all sources of ignition. Prevent entry into waterways, sewers, basements or confined areas. Ethanol vapors are heavier than air and may travel a considerable distance to a source of ignition and flash back. Alcohols burn with a pale blue flame which may be extremely hard to see under normal lighting conditions. Personnel may only be able to feel the heat of the fire without seeing flames. Extreme caution must be exercised in fighting alcohol fires. When exposed to ignition source in air, vapors can burn in open or explode if confined. Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Heat may build enough pressure to rupture closed containers/spreading fire/increasing risk of burns/injuries. Cool containers with flooding quantities of water until well after SAFETY DATA SHEET SDA3C/200PF/IPA/140500 Gen. Variant: SDS_US_GHS Version 1.4 Revision Date 11/22/2019 Print Date 02/10/2020 SDS No.: 840 5 / 18 fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. Always stay away from tanks engulfed in fire. Move containers from fire area if it can be done without risk. Prevent fire extinguishing water from contaminating surface water or the ground water system. When fighting a fire, notify environmental authorities if liquid enters sewers or public waters. Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations. Special protective equipment for fire-fighters : Wear positive pressure self-contained breathing apparatus (SCBA). Structural firefighter’s protective clothing will only provide limited protection. 6. ACCIDENTAL RELEASE MEASURES Personal precautions : Clean-up to be performed only by trained and properly equipped personnel. Wear recommended personal protective equipment. Eliminate all sources of ignition. Ensure adequate ventilation. Evacuate personnel to safe areas. Environmental precautions : If necessary, all contaminated waste water must be treated in a municipal or industrial wastewater treatment plant before release to surface water. Chemical removal by air and water pollution control devices must meet the minimum efficiency requirements needed to reduce exposures to an acceptable level. The discharge of treatment plant effluent to rivers and oceans must achieve the dilution ratio needed to reduce exposures to an acceptable level. The size and capacity of wastewater treatment plants must meet the minimum requirements needed to reduce exposures to an acceptable level. Waste management practices such as incineration, recycling, reuse must be enforced as needed to reduce exposures to an acceptable level. External treatment and disposal of waste should comply with applicable local and/or national regulations. The maximum allowable site tonnage and the days of use should be below the number needed to maintain exposures at an acceptable level. SAFETY DATA SHEET SDA3C/200PF/IPA/140500 Gen.
