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 (8) 3-unit townhome complexes, two (2) 4-unit townhome complexes, and two (2) 8-unit townhome complexes. This report has been prepared for Townes at LoSo Building 1001 which includes a total of eight (8) townhome units (Units 1-8) constructed in the eastern portion of the Site. A Site location map is provided as Figure 1, and a Site Plan that identifies Building 1001 is shown in Figure 2. A table listing the unit numbers, associated monitoring point identifications (see Section 2.0), and unit addresses for Building 1001 is included below. 2 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/NVR, Inc/NVR-013 Blythe-Isenhour/VIMS Install Reports/Building 1001/Report/VIMS Installation Completion Report_Building 1001.docx Building 1001 Unit Number Address Associated monitoring point ID 1 4930 Old Pineville Road MP-1001-1 2 4928 Old Pineville Road MP-1001-2 3 4926 Old Pineville Road MP-1001-3 4 4924 Old Pineville Road MP-1001-4 5 4922 Old Pineville Road MP-1001-5 6 4920 Old Pineville Road MP-1001-6 7 4918 Old Pineville Road MP-1001-7 8 4916 Old Pineville Road MP-1001-8 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. 3 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/NVR, Inc/NVR-013 Blythe-Isenhour/VIMS Install Reports/Building 1001/Report/VIMS Installation Completion Report_Building 1001.docx In accordance with the DEQ Brownfields Program Minimum Requirements for Townhome Developments 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 1001 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. 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 1001/Report/VIMS Installation Completion Report_Building 1001.docx 2.0 VIMS Installation and Influence Testing Building 1001 consists of eight (8) individually owned three-story townhomes that contain a monolithic slab on-grade foundation and concrete footings below load bearing walls. Each unit includes a stairwell, garage, and/or living spaces located on the ground floor of the structure. The ground floor for each townhome unit is approximately 640 square feet. Further, each unit contains a small attic space to house mechanical equipment and a sloped roof. 2.1 VIMS Installation The DEQ-approved VIMP included installation of Vaporblock® Plus 20 (VBP20) vapor barrier manufactured by Raven Industries (Raven) 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 Raven 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. Because these units contain ground floor garages adjacent to living spaces, the VIMS and sub-slab vapor extraction treatment was extended below the ground-level garages of the townhomes. Sub-slab vapor extraction 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 5 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/NVR, Inc/NVR-013 Blythe-Isenhour/VIMS Install Reports/Building 1001/Report/VIMS Installation Completion Report_Building 1001.docx 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 Empire Eveco EV04SS (stainless steel) stationary wind ventilator on reach riser discharge that is designed to promote air exhaust from the riser piping. Each townhome unit contains an individual sub-slab vent system, riser pipe, monitoring point, and a stationary ventilator. Product specification sheets for the Eveco 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 1001, 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: • 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; 6 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/NVR, Inc/NVR-013 Blythe-Isenhour/VIMS Install Reports/Building 1001/Report/VIMS Installation Completion Report_Building 1001.docx • after completion of the monitoring point access ports; 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 March 2, 2023, H&H completed influence testing for Building 1001 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 0.355 in-WC to 0.756 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 1001/Report/VIMS Installation Completion Report_Building 1001.docx 3.0 Sub-Slab Soil Gas Assessment Activities Following successful installation of the VIMS, H&H collected three sub-slab soil gas samples (SS- 1001-1, SS-1001-4, and SS-1001-7) for laboratory analysis from Building 1001. 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 March 28, 2023, H&H collected three sub-slab soil gas samples from permanent monitoring points in Building 1001. 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-1001-1 (sample ID SS- 1001-1), MP-1001-4 (sample ID SS-1001-4), and MP-1001-7 (sample ID SS-1001-7), as shown on VM-2 (Appendix C). One duplicate sub-slab soil gas sample (SS-1001-DUP) was collected for quality assurance/quality control (QA/QC) purposes during the event from the SS-1001-4 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 8 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/NVR, Inc/NVR-013 Blythe-Isenhour/VIMS Install Reports/Building 1001/Report/VIMS Installation Completion Report_Building 1001.docx shroud and used to purge a minimum of three volumes (monitoring point and sample train) of soil 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 and 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 January 2023. The laboratory analytical report with chain of custody record is provided as Appendix F. The sub-slab soil gas sample analytical results indicate that multiple compounds were detected above the laboratory method detection limit (MDL) in each sample, but no compounds were detected above the Residential SGSLs. The chlorinated solvent, tetrachloroethene (PCE), was detected above the laboratory MDL at a concentration of 35.3 μg/m3 at sample location SS-1001- 9 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/NVR, Inc/NVR-013 Blythe-Isenhour/VIMS Install Reports/Building 1001/Report/VIMS Installation Completion Report_Building 1001.docx 1, but this concentration is well below the Residential SGSL of 280 μg/m3. The chlorinated solvent trichloroethene (TCE) was not detected above the laboratory MDL at any sample location. Acetone, 2-butanone (methyl ethyl ketone), and tetrahydrofuran were detected at concentrations that are orders of magnitude above the other compounds detected in each sample, but each detected is well below the Residential SGSLs. 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 (January 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 1001 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 5.9 x 10-7 and a HI value of 0.12. The calculated cumulative residential use LICR and HI values are 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 1001. 10 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/NVR, Inc/NVR-013 Blythe-Isenhour/VIMS Install Reports/Building 1001/Report/VIMS Installation Completion Report_Building 1001.docx 4.0 Summary and Conclusions Construction of townhome Building 1001 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 11 additional 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 1001, 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 don’t indicate that there is unacceptable vapor intrusion risk from Site contaminants to the occupants of Building 1001 and no further pre- occupancy sampling is recommended for this building. In accordance with the DEQ approved VIMP, two post-construction sub-slab soil gas sampling events will be completed on an annual basis with the first annual event for Building 1001 expected to be conducted in Spring 2024. Upon completion of each sampling event, a report will be submitted to DEQ along with an evaluation of the analytical data and VIMS effectiveness. In addition, in accordance with the VIMP, an operations & maintenance (O&M) plan will be prepared near the end of construction of the Townes at LoSo development which will describe further on- going maintenance activities for the VIMS as warranted. 11 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/NVR, Inc/NVR-013 Blythe-Isenhour/VIMS Install Reports/Building 1001/Report/VIMS Installation Completion Report_Building 1001.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.

VBP20 UNDER-SLAB VAPOR / GAS BARRIER Under-Slab Vapor/Gas Retarder © 2018 RAVEN INDUSTRIES INC. All rights reserved. VAPORBLOCK® PLUS™VBP20 PRODUCT DESCRIPTION VaporBlock® Plus™ is a seven-layer co-extruded barrier made using high quality virgin-grade polyethylene and EVOH resins to provide unmatched impact strength as well as superior resistance to gas and moisture transmission. VaporBlock® Plus™ 20 is more than 100 times less permeable than typical high-performance polyethylene vapor retarders against Methane, Radon, and other harmful VOCs. Tested and verified for unsurpassed protection against BTEX, HS, TCE, PCE, methane, radon, other toxic chemicals and odors. VaporBlock® Plus™ 20 multi-layer gas barrier is manufactured with the latest EVOH barrier technology to mitigate hazardous vapor intrusion from damaging indoor air quality, and the safety and health of building occupants. VBP20 is one of the most effective underslab gas barriers in the building industry today far exceeding ASTM E-1745 (Plastic Water Vapor Retarders Used in Contact with Soil or Granular Fill Under Concrete Slabs) Class A, B and C requirements. Available in a 20 (Class A) mil thicknesses designed to meet the most stringent requirements. VaporBlock® Plus™ 20 is produced within the strict guidelines of our ISO 9001 Certified Management System. PRODUCT USE VaporBlock® Plus™ 20 resists gas and moisture migration into the building envelop when properly installed to provide protection from toxic/harmful chemicals. It can be installed as part of a passive or active control system extending across the entire building including floors, walls and crawl spaces. When installed as a passive system it is recommended to also include a ventilated system with sump(s) that could be converted to an active control system with properly designed ventilation fans. VaporBlock® Plus™ 20 works to protect your flooring and other moisture-sensitive furnishings in the building’s interior from moisture and water vapor migration, greatly reducing condensation, mold and degradation. SIZE & PACKAGING VaporBlock® Plus™ 20 is available in 10’ x 150’ rolls to maximize coverage. All rolls are folded on heavy-duty cores for ease in handling and installation. Other custom sizes with factory welded seams are available based on minimum volume requirements. Installation instructions and ASTM E-1745 classifications accompany each roll. APPLICATIONS Radon Barrier Methane Barrier VOC Barrier Brownfields Barrier Vapor Intrusion Barrier Under-Slab Vapor Retarder Foundation Wall Vapor Retarder VaporBlock® Plus™ is a seven-layer co-extruded barrier made using high quality virgin-grade polyethylene and EVOH resins to provide unmatched impact strength as well as superior resistance to gas and moisture transmission. VaporBlock® Plus™ Placement All instructions on architectural or structural drawings should be reviewed and followed.

SOIL GAS COLLECTOR MAT Installation Guide Radon Ready New Construction Time-saving, low-cost solution Easy Installation Reduce Liability! Used in all 50 states and Internationally Complian under multiple codes: AARST-ANSI, ASTM, IRC Appendix F, EPA, HUD, and more! 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 ADVANTAGES NO TRENCHINGNO BACKFILLNO VAPOR BARRIER* It’s called SOIL gas mat for a reason, Place directly on soil or substrate. Low-profile (1” thick) gas mat does not require trenching. SAFETY DATA & PRODUCT DATA SHEETS AVAILABLE @ www.RADONMAT.com 3 INSTALLATION INSTRUCTIONS 1. Begin work on the sub grade (soil or gravel) after the final preparation and before the concrete is poured. Start with T-Riser(s) and work out to ensure smooth mat placement. Position the T-Riser(s) in appropriate location(s) and nail down with a 12” steel nail (T Nail) through precut center hole. 2. Slide mat into flat openings on either end of T-riser with a portion of the fab- ric around the outside. Tape the fabric to the outside of the T-Riser with duct tape and staple mat to the ground with landscape staples to ensure soil contact remains during pour stage. 3. Mat is typically laid out in a rectangular loop in the largest area with branch- es or legs into smaller areas (FREE plan design at www.radonmat.com). There is no need to trench the mat. Roll out the SGC mat, smooth it onto the ground. To avoid wrinkles and buckling, work away from the risers, stapling to the ground as you go. The mat should be stapled every three to four feet, in addi- ton to corners, tee junctions & ends. 5. Corners are constructed by peeling back the filter fabric, cutting two ends of the matrix at 45 degree angles and butting (or overlapping: no more than 1/2”) the matrix together. Pull the filter fabric back and tape into place. Staple across the joint of the matrix and each leg of the corner. Use a minimum of four staples at each corner-- two across the joint and one on each leg. 6. The tees for branches and legs are constructed by slitting the fabric of the main loop at the location desired. Cut the fabric of the branch at the edges and expose two inces of the matrix. Cut off the exposed matrix and but the ma- trix of the branch (or overlap 1/2”)to the matrix of hte main loop. Pull the flter fabric of the branch back over the main loop and tape into place. Staple across joint of the matrix with two staples and one each on the branch and main loop. Use a minimum of four staples at each tee, two across the joint and one on each loop and branch. 4 7. All openings in the fabric at joints, tee’s, and ends of branches should be taped to keep out concrete. 8. Stub up a few feet of 4” schedule 40 PVC* from all T risers before pour (or cover T riser with duct tape). Seal with polyurethene caulk and screws. This ensures no concrete aggregate enters the riser during slab pour. Be sure to label “CAUTION RADON REDUCTION SYSTEM” on all pipe. *(6” PVC may be substituted--for large multifamily projects. Simply cut T riser 4” insert away to reveal 6” insert). 9. When the building is ready for the vent pipe to be installed above the slab, fit to pre-stubbed PVC with PVC straight connect. If PVC was not preset, cut duct tape from riser and insert 4” PVC pipe now. Seal with polyurethene caulk and secure with screws. Always label “CAUTION RADON REDUCTION SYSTEM” to avoid confusion on site and for the building occupants. note: The openings in the riser are laid out at 180 degrees to accomodate straight runs of mat. However, if the riser is to be placed in a corner, which is not uncommon, the front of the T can be cut and the SGC mat inserted into the new opening. The side of the T that is unused should be sealed with tape. This creates a 90 degree T which will allow corner placement for the riser. Mat should always enter the T riser from at least two directions and exhaust to pipe vertically. SAFETY DATA & PRODUCT DATA SHEETS AVAILABLE @ www.RADONMAT.com 5 MAKING CORNERS AND SPLICES The mat should be routed around the inside perimeter of the foundation. This will require occasional corner junctions. Furthermore, splices will have to be made to join two lengths of mat together. Corners and splices are very easy to make, and do not require any special fittings. Cut back the filter fabric to reveal the core material. In the case of a splice, merely overlap the core by at least one corrugation, replace the cloth, and tape it. Use two landscape staples to hold the splice in place. In the case of a corner, peel back geotextile fabric and slice the core of the two adjoining legs at 45 degree angles which mirror each other; overlap the edges by one corrugation; return grey geotextile fabric, tape and staple the corner together. 6 CONNECTING THE MAT TO THE T RISER A convenient T-riser with dual entry al- lows for either end of the loop of mat to be secured to the riser. Slide the mat into each end of the riser and tape the edge to prevent wet concrete from entering. Cap the riser to ensure no concrete enters. T Riser caps can be purchased in leui of duct tape. A pres- tub of PVC pipe can also serve the same purpose.

The only precaution that needs to be taken is that the fabric is duct taped closed at seams of splices and corner to sufficiently keep the uncured concrete from en- tering. The mat also needs to be secured to the soil with landscape staples to prevent the concrete from lifting off the soil while it is being applied. Re-enforcing bars and wire can be laid on top of the mat. Note: the mat is strong enough (4,300 psf) to withstand concrete workers and their wheel barrows. 10 Appendix C VIMS As-Built Drawings VIMS VAPOR LINER AND BASE COURSE (TYP)1 BASE COURSE - CLEAN #57 STONE MIN 4" THICK BENEATH VIMS VAPOR LINER VAPOR LINER (SEE SPECIFICATION #4) CONCRETE FLOOR SLAB SUBBASE NTSVM1 SECTION THROUGH TURNED DOWN SLAB AT DRIVEWAY4 NTSVM1 VAPOR LINER 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.

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.
