The Blythe Isenhour Brownfields property totals approximately 1.67 acres of land. The Townes at LoSo development plan includes construction of 12 buildings consisting of 46 for- sale townhome units by Ryan Homes, an NVR, Inc. (NVR) company. The buildings include eight 3-unit townhome complexes, two 4-unit townhome complexes, and two 8-unit townhome complexes. This report has been prepared for Townes at LoSo Building 1010 which includes a total of three townhome units (Units 40, 41, & 42) constructed in the central portion of the Site. A Site location map is provided as Figure 1, and a Site Plan that identifies Building 1010 is shown in Figure 2. A table listing the unit numbers, associated monitoring point identifications (see Section 2.0), and unit addresses for Building 1010 is included below. Building 1010 Unit Number Address Associated Monitoring Point ID 40 6231 Cleburne Court MP-1010-40 41 6227 Cleburne Court MP-1010-41 42 6223 Cleburne Court MP-1010-42 2 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/NVR, Inc/NVR-013 Blythe-Isenhour/VIMS Install Reports/Building 1010/Report/VIMS Install Report_Bldg 1010.docx H&H previously completed soil, groundwater, soil gas, and sub-slab soil gas sampling assessment activities for the Site in Mach 2020 to evaluate subsurface conditions for potential impacts. Results of previous groundwater assessment activities completed in hydraulically upgradient and downgradient portions of the Site did not identify volatile organic compounds (VOCs) at concentrations above the DEQ 2L Groundwater Standards or the DEQ Division of Waste Management (DWM) Residential Vapor Intrusion Groundwater Screening Levels (VISL). Results of previous exterior soil gas assessment activities completed at the Site identified benzene, ethylbenzene, naphthalene, 1,2,4-trimethylbenzene, and 1,3,5-trimethylbenzene in soil gas samples at concentrations above their respective DWM Residential Soil Gas Screening Levels (SGSLs). For ease of reference, the March 2020 data summary tables and a sample location map are included in Appendix A. A Brownfields Agreement between Boulevard at 4920 Old Pineville Road, LLC and DEQ was recorded for the Site on December 10, 2021. Boulevard has since sold a portion of the property to NVR. Although results of the assessment do not indicate the potential for structural vapor intrusion, based on the DEQ Brownfields requirements for townhome developments, installation of a minimum of a vapor intrusion mitigation system (VIMS) is needed for each townhome building. In accordance with the DEQ Brownfields Program Minimum Requirements for Townhome Developments (Townhome Checklist) document, and to be in general compliance with the Brownfields Agreement, the prospective developer (PD) will install a passive VIMS during construction of each proposed townhome building. H&H prepared the Vapor Intrusion Mitigation Plan (VIMP) and revisions to the VIMP based on DEQ comments. The final VIMP dated February 7, 2022, was approved by DEQ in a letter dated March 3, 2022. The DEQ-approved VIMP includes installation of a passive VIMS in each of the townhome buildings and post-installation sub-slab soil gas sampling. This report documents installation of the VIMS for Building 1010 at the Townes at LoSo development. Following installation of the VIMS in other Site townhome buildings and completion of post-construction sampling, additional VIMS installation completion reports will be submitted under separate cover. 3 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/NVR, Inc/NVR-013 Blythe-Isenhour/VIMS Install Reports/Building 1010/Report/VIMS Install Report_Bldg 1010.docx A discussion of VIMS installation activities and influence testing is provided in Section 2.0, a summary of sub-slab soil gas assessment activities is provided in Section 3.0, and summary and conclusions based on the results of the VIMS installation and soil gas assessment activities are provided in Section 4.0, and the engineer’s certification is provided in Section 5.0. 4 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/NVR, Inc/NVR-013 Blythe-Isenhour/VIMS Install Reports/Building 1010/Report/VIMS Install Report_Bldg 1010.docx 2.0 VIMS Installation and Influence Testing Building 1010 consists of three individually owned three-story townhomes that contain a monolithic slab on-grade foundation with concrete footings below load bearing walls. Each unit includes a stairwell, two car garage, and a foyer located on the ground floor of the structure. The ground floor for each townhome unit is approximately 640 square feet. The second and third floors contain residential livings spaces. Each building also contains a sloped roof with an attic space located above the third floor that is used to house mechanical equipment. The attic is not designed nor constructed to be a living space. 2.1 VIMS Installation The DEQ-approved VIMP included installation of Vaporblock® Plus 20 (VBP20) vapor barrier manufactured by Viaflex Inc., (Viaflex), previously known as Raven Industries, beneath the concrete slab-on-grade and blocks walls of the townhouse buildings. VBP20 is an ASTM-certified 20-mil, multi-layer, chemically resistant vapor barrier, designed to prevent the migration of VOCs. Technical specifications and installation instructions obtained from Viaflex for the VBP20 vapor barrier are provided in Appendix B. Based on the inspections described below, the vapor barrier was installed per manufacturer installation instructions (Appendix B). Briefly, VBP20 was installed by the construction contractor to cover the ground surface below the entire area of the buildings’ ground floor slabs. The exterior edges of the VBP20 were set under the concrete foundations and installed below the monolithic footings at the tenant separation walls. Seams within the building footprint have a minimum 12-inch overlap and were sealed with VaporSeal™ tape. Small puncture holes and utility penetrations were sealed with VaporSeal™ tape. The VIMP also included installation of a passive mitigation system beneath the ground-level slab to reduce the potential for vapor intrusion into the townhome units by vapor extraction. The units contain ground floor garages adjacent to the foyer so the VIMS and sub-slab vapor extraction piping was extended below the ground-level garages of the townhomes. Sub-slab vapor extraction 5 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/NVR, Inc/NVR-013 Blythe-Isenhour/VIMS Install Reports/Building 1010/Report/VIMS Install Report_Bldg 1010.docx is accomplished using soil gas collector mats manufactured by Radon Professional Discount Supply (Radon PDS). The soil gas collector mat is a polystyrene plastic rectangular conduit with a geotextile fabric covering that is 1-inch thick and 12-inches wide specifically designed for collecting soil gas from below a building. The soil gas collector mat was connected to the vertical risers using Radon PDS manufactured riser connector fittings in accordance with the manufacturer installation instructions. The vertical risers consist of 3-inch diameter Sch 40 PVC pipes and fittings that run from the slab through the upper floors and the attic space, then terminate above the building’s roofline. The passive VIMS is also enhanced with an Active Ventilation Aura AV-3-PVC (aluminum) stationary wind ventilator that is designed to promote air exhaust from the conveyance piping. Each townhome unit contains an individual sub-slab vent system, riser conveyance piping, monitoring point, and a stationary ventilator. Product specification sheets for the stationary ventilator and soil gas collector mat are included in Appendix B. To further enhance sub-slab vapor transmission and collection effectiveness, a uniform layer of high permeability stone (clean #57) was installed directly below the concrete slab to allow for air movement beneath the entirety of the slab. Soil gas collector mats were installed within the high permeability stone layer. The thickness of the high permeability stone around the collector mats extends a minimum of 2-inches below the mats, and the top of the mat is set flush with the completed stone layer, or approximately 1-inch below the top of the stone. In areas without soil gas mat, a minimum thickness of 4 inches of clean #57 stone was installed. In the event the system needs to be activated with electric fans, one vacuum monitoring point was installed for each townhome unit to measure the pressure differential between indoor air and the sub-slab, and for collection of sub-slab soil gas samples. The locations of the monitoring points are depicted in the as-built drawings provided in Appendix C. During installation of the VIMS in Building 1010, H&H conducted inspections during various phases of construction to confirm the VIMS was installed in accordance with the VIMP. Inspections were completed during the following phases: 6 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/NVR, Inc/NVR-013 Blythe-Isenhour/VIMS Install Reports/Building 1010/Report/VIMS Install Report_Bldg 1010.docx • after installation of sub-slab soil gas collector mat and monitoring points within the gravel base; • following placement and sealing of the vapor barrier and prior to pouring the concrete building slab; and • after installation of vertical exhaust riser pipe and ventilator fan installations. Based upon inspections completed during the VIMS installation activities, the VIMS was installed in general accordance with the DEQ-approved VIMP. VIMS details and specifications, and a VIMS as-built drawing which depicts the VIMS layout are included in Appendix C. A representative photographic log of the VIMS installation activities is provided in Appendix D. 2.2 VIMS Influence Testing On September 28, 2023, H&H completed influence testing for Building 1010 to evaluate system sub-slab communication and to confirm that adequate vacuum can be obtained should an active depressurization system be needed in the future. DEQ considers 4 Pascals (Pa), or 0.016-inches of water column (in-WC), differential pressure the minimum vacuum needed for an active depressurization system to effectively treat potential structural vapor intrusion. H&H connected RadonAway RP-145 fans, which are standard radon mitigation-style electric fans, to the vertical riser piping to model an active depressurization system. Differential pressure measurements were collected at each vacuum monitoring point using a Dwyer series 475 Mark III Digital manometer (capable of measuring to 0.001 in-WC or 0.25 Pa) to establish baseline conditions prior to use of the electric fans. Following collection of baseline differential pressure measurements, the electric fans were turned on and differential pressure measurements were collected at each riser and monitoring point over varied time intervals. Results of the influence tests indicated sub-slab vacuum measured at the monitoring points ranged from 0.400 in-WC to 0.955 in-WC, which demonstrates adequate sub-slab system communication, and that sufficient vacuum can easily be achieved below the slab of each unit with a standard electric fan. The locations of the permanent monitoring points (denoted by MP nomenclature) are shown on Sheet VM-2 (Appendix C). The summary table of the influence test results is included in Appendix E. 7 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/NVR, Inc/NVR-013 Blythe-Isenhour/VIMS Install Reports/Building 1010/Report/VIMS Install Report_Bldg 1010.docx 3.0 Sub-Slab Soil Gas Assessment Activities Following successful installation of the VIMS, H&H collected two sub-slab soil gas samples for laboratory analysis from Building 1010. The sub-slab assessment activities were conducted in accordance with the DEQ-approved VIMP and DEQ Division of Waste Management (DWM) Vapor Intrusion Guidance (Guidance) dated March 2018. 3.1 Sub-Slab Soil Gas Sampling On November 20, 2023, H&H collected two sub-slab soil gas samples from permanent monitoring points in Building 1010. The sampling was performed following VIMS installation activities and approximately two weeks after installation of the stationary ventilators. The sub-slab soil gas samples were collected from permanent monitoring point locations MP-1010-40 (sample ID SSV- 1010-40) and MP-1010-42 (sample ID SSV-1010-42) as shown on VM-2 (Appendix C). One duplicate sub-slab soil gas sample (SSV-1010-DUP) was collected for quality assurance/quality control (QA/QC) purposes during the event from the SSV-1010-40 parent location. The duplicate sample was collected utilizing a laboratory supplied stainless-steel sampling “T” which allows for the simultaneous collection of two sub-slab soil gas samples from a single location. To collect the sub-slab soil gas samples, Teflon sample tubing was attached to a 2-inch expandable well cap with a sampling port that was secured onto the 2-inch diameter PVC monitoring point. The tubing was connected to an airflow regulator and laboratory-supplied batch-certified 1-liter stainless steel Summa canister. The air flow regulator was preset by the laboratory to collect a soil gas sample at a flow rate no greater than approximately 100 milliliters per minute. Prior to sample collection, H&H conducted a leak test at each monitoring point by placing a shroud around the monitoring point, expandable well cap, and sampling train including the Summa canister. The air within the shroud was flooded with helium gas and concentrations were measured with a calibrated helium detector. Helium concentrations within the shroud were maintained at approximately 10%. A GilAir vacuum pump was connected to the sample tubing outside of the shroud and used to purge a minimum of three volumes (monitoring point and sample train) of soil 8 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/NVR, Inc/NVR-013 Blythe-Isenhour/VIMS Install Reports/Building 1010/Report/VIMS Install Report_Bldg 1010.docx gas into a Tedlar® bag at each sampling point. The helium gas detector was used to measure helium concentrations within the Tedlar bag sample to confirm helium concentrations in the sample were less than 10% of that measured within the shroud. Results of the helium leak checks indicate that helium was not detected in the purge air above the threshold which indicates unacceptable short-circuiting at the monitoring points or within the sampling train were not present. Soil gas sampling field forms completed by sampling personnel are included in Appendix E. Following a successful leak check, the air flow regulators were opened to allow collection of the sub-slab soil gas samples. Vacuum in the Summa canisters was monitored during the sampling event to confirm adequate sample volume was collected at each monitoring point location. Upon completion of sample collection, the air flow regulator was closed to the Summa canister. The canisters were labeled with the sample identification, beginning and ending times, pressure measurements, and the requested analysis. The canisters were then placed in laboratory supplied shipping containers and delivered to Waypoint Analytical (Waypoint) under standard chain of custody protocols for analysis of volatile organic compounds (VOCs) by Environmental Protection Agency (EPA) Method TO-15. 3.2 Sub-Slab Soil Gas Sampling Results The sub-slab soil gas sample analytical results are summarized in Table 1. The results were compared to the DEQ DWM Residential Vapor Intrusion Sub-Slab and Exterior Soil Gas Screening Levels (SGSLs) dated July 2023. The laboratory analytical report with chain of custody record is provided as Appendix F. The parent and duplicate sample concentrations indicated comparable concentrations were detected by the laboratory for these samples. The sub-slab soil gas sample analytical results indicate that multiple compounds were detected above the laboratory method detection limits (MDLs), but below the respective Residential SGSLs, in each sample, with the exception of the VOC chloroform. Chloroform was the only compound detected above its Residential SGSL of 4.1 μg/m3, with concentrations of 7.84 μg/m3 and 7.77 μg/m3 in samples SSV-1010-40 and SSV-1010-DUP, respectively. The chlorinated 9 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/NVR, Inc/NVR-013 Blythe-Isenhour/VIMS Install Reports/Building 1010/Report/VIMS Install Report_Bldg 1010.docx solvent compounds tetrachloroethene (PCE) and trichloroethene (TCE) were not detected above the laboratory MDL in either sub-slab soil gas sample. Acetone, 2-butanone (methyl ethyl ketone), and tetrahydrofuran were detected at concentrations up to two orders of magnitude above the other compounds detected in each sample, but each detection is well below its respective Residential SGSL. Acetone and 2-butanone are two of the main components in PVC primer, and tetrahydrofuran is one of the main components in PVC glue. PVC primer and glue are common construction materials used throughout construction of the townhome units, including on the sub-slab plumbing pipes. Material safety data sheets for PVC glue and primer used during construction are included as Appendix G. The DEQ DWM Vapor Intrusion SGSLs are very conservative and based on a target carcinogenic risk (TCR) for potential carcinogenic risks of 1 x 10-6 and a hazard quotient (HQ) of 0.2 for potential non-carcinogenic risks. The DEQ and EPA acceptable risk level for potential carcinogenic risks is a cumulative lifetime incremental cancer risk (LICR) of 1 x 10-4 or less and the acceptable level for non-carcinogenic risks is a cumulative hazard index (HI) of 1 or less. The HI is the sum of HQs for each target analyte. H&H utilized the DEQ Risk Calculator (July 2023) to confirm there are no potential vapor intrusion risks at unacceptable levels. H&H modeled a worst-case scenario by using the highest concentrations of any compound detected below Building 1010 in a residential use scenario to conservatively evaluate potential vapor intrusion risks. The calculated cumulative LICR and HI values are provided in Table 1, and a copy of the completed DEQ Risk Calculator is provided in Appendix H. As shown in Table 1, results of the worst-case risk calculations indicate a calculated cumulative LICR of 2.2 x 10-6 and a HI value of 0.036. The calculated cumulative residential use LICR and HI values are well within the DEQ and EPA acceptable levels. These risk calculator results confirm that compound concentrations detected below the slab do not pose vapor intrusion risks at unacceptable levels within the townhome units at Building 1010. 10 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/NVR, Inc/NVR-013 Blythe-Isenhour/VIMS Install Reports/Building 1010/Report/VIMS Install Report_Bldg 1010.docx 4.0 Summary and Conclusions Construction of townhome Building 1010 of the Townes at LoSo development has been completed at the Blythe Isenhour Brownfields property (Brownfields Project No. 23067-19-060) located in Charlotte, North Carolina. The Townes at LoSo redevelopment includes construction of 12 townhome buildings at the Brownfield property, and separate reports will be submitted to document installation of the VIMS in the other buildings. During construction of Building 1010, H&H conducted VIMS installation inspections to confirm the system was installed as designed and completed post-installation sub-slab soil gas sampling activities to evaluate efficacy of the system. The VIMS installation inspections and post- installation sampling activities were completed in general accordance with the DEQ-approved VIMP. Based on the VIMS installation inspections, influence testing, and post-installation sub-slab soil gas sampling results, the VIMS is effectively mitigating potential vapor intrusion risks from Site contaminants. The sub-slab soil gas to indoor air risk calculator results confirms that the cumulative LICR risk and the noncarcinogenic HI risk are within DEQ and EPA acceptable levels. Based on the evaluation, the analytical samples do not indicate that there is unacceptable vapor intrusion risk from Site contaminants to the occupants of Building 1010 and no further pre- occupancy sampling is recommended for this building. In accordance with the DEQ approved VIMP, two post-occupancy sub-slab soil gas sampling events will be completed on an annual basis with the first annual event for Building 1010 expected to be conducted in Fall 2024. Note, depending upon the future sub-slab soil gas analytical data, indoor air sampling may be warranted during future monitoring events. Upon completion of each sampling event, a report will be submitted to DEQ along with an evaluation of the analytical data and VIMS effectiveness. Based on the post-occupancy analytical data and in accordance with the Townhome Checklist, a request to reduce sampling to once every five years, or as otherwise approved by DEQ, may be submitted for DEQ review and approval. In addition, in accordance with the VIMP, an Operations & Maintenance (O&M) Plan will be prepared near the end of 11 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/NVR, Inc/NVR-013 Blythe-Isenhour/VIMS Install Reports/Building 1010/Report/VIMS Install Report_Bldg 1010.docx construction of the Townes at LoSo development which will describe further on-going maintenance activities for the VIMS as warranted. 12 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/NVR, Inc/NVR-013 Blythe-Isenhour/VIMS Install Reports/Building 1010/Report/VIMS Install Report_Bldg 1010.docx 5.0 Engineer’s Certification According to the DWM Vapor Intrusion Guidance: “Risk-based screening is used to identify sites or buildings likely to pose a health concern, to identify buildings that may warrant immediate action, to help focus site-specific investigation activities or to provide support for building mitigation and other risk management options including remediation.” In addition, this VIMP was prepared to satisfy the standard vapor intrusion mitigation provisions anticipated to be included in the Brownfields Agreement. Per the North Carolina Brownfields Property Reuse Act 130A- 310.32, a prospective developer, with the assistance of H&H for this project, is to provide DEQ with “information necessary to demonstrate that as a result of the implementation of the brownfields agreement, the brownfields property will be suitable for the uses specified in the agreement while fully protecting public health and the environment instead of being remediated to unrestricted use standards.” It is in the context of these risk-based concepts that the H&H professional engineer makes the following statement: The Vapor Intrusion Mitigation System (VIMS) detailed herein was designed to mitigate intrusion of subsurface vapors into the subject building from known Brownfields Property contaminants in a manner that is in accordance with the most recent and applicable guidelines including, but not limited to, DWM Vapor Intrusion Guidance, Interstate Technology & Regulatory Council (ITRC) guidance, and American National Standards Institute (ANSI)/American Association of Radon Scientists and Technologists (AARST) standards. The sealing professional engineer below is satisfied that the design and its installation are fully protective of public health from known Brownfields Property contaminants.

Simple, modern solutions for soil gases: radon, vapor, and VOCs www.RadonMat.comPhotos, videos, & more @ MADE IN THE USA SOIL GAS COLLECTOR MAT FOR RADON READY NEW CONSTRUCTION According to the US EPA’s model stan-dards for radon control systesm in new building construction, a means for col-lecting soil gas should be installed be-neath the slab. More and more mitigators and buildiers are using PDS’ soil gas collector mat because its installation does not entail any special coordination with plumb-ers or other site contractors. Low pro-file mat saves time as it removes the need for trenching. Just lay radon mat down around the inside perimeter of the foundation, secure it with spikes or landscaping staples, and pour the con-crete. SGC mat is superior to other mat sys-tems because of its thickness and it has a geotextile fabric cloth surround-ing the entire mat material. This fea-ture eliminates the ened to lay a plas-tic barrier or sheet on top of the mat to protect the matrix. Using plastic sheeting can cause concrete cracking due to differential dewatering. The full fabric design greatly enhances both the installation as well as the quality of the concrete slab. When SGC mat is in-stalled below the slab, you’re providing an airspace that intercepts radon--and other soil gases and vapors--before it seeps into the building through the slab. SGC mat also works well as a soil gas collector beneath crawlspace bar-rier due to its low-profile. WHY & HOW IT WORKS The matting is a one inch high by twelve inch wide matrix enveloped in a geotextile filter fabric. 90% of the geomatrix is airspace, which means soil gas has room to move to the col-lection point. This creates incredible pressure field extension for post con-struction system activation. The mat can support concrete without com-pressing, yet is extremely lightweight and easy to handle. This system allows for radon to flow through teh filter fabric and into the airspace. The airspace does not clog because the filter fabric retains teh underlying gravel and soil. The natural airflow through the mat then channels the radon to the T riser to pipe connec-tion. From there, hazardous gas can be vented safely through the roof of the building. Another key element of a soil gas col-lection system is attaching the 4” riser to the mat, such that airflow is not restricted at this critical juncture. The soil gas T riser is unique as it has three ports, two redundant mat entries and one PVC connection to outside air. This unique fitting connects all three sides without special connections or fittings. common duct tape and caulk does the trick. 2 Appendix C VIMS As-Built Drawings VIMS VAPOR BARRIER AND BASE COURSE1 BASE COURSE - CLEAN #57 STONE MIN 4" THICK BENEATH VIMS VAPOR BARRIER VAPOR BARRIER (SEE SPECIFICATION #4) CONCRETE FLOOR SLAB SUBBASE NTSVM1 SECTION THROUGH TURNED DOWN SLAB AT DRIVEWAY4 NTSVM1 VAPOR BARRIER SEALED TO CONCRETE PER MANUFACTURER INSTRUCTIONS.

Germ cell mutagenicity Carcinogenicity In 2012 USEPA Integrated Risk Information System (IRIS) reviewed a two species inhalation lifetime study on THF conducted by NTP (1998). Male rats developed renal tumors and female mice developed liver tumors while neither the female rats nor the male mice showed similar results. Because the carcinogenic mechanisms could not be identified clearly in either species for either tumor, the EPA determined that the male rat and female mouse findings are relevant to the assessment of carcinogenic potential in humans. Therefore, the IRIS review concludes that these data in aggregate indicate that there is "suggestive evidence of carcinogenic potential" following exposure to THF by all routes of exposure.
