By: ________________________ Date: DRAFT Stephen Hilfiker, P.G. Project Manager Site Investigation and Remediation VHB Soil Management Plan 1 Introduction and Background 1 Introduction and Background Vanasse Hangen Brustlin, Inc. (“VHB”) was retained by Jacobs Engineering Group, Inc. (“Jacobs”) to conduct soil pre-characterization sampling, proactively design a sub-slab depressurization system (“SSDS”) in the event it is needed, and prepare a Soil Management Plan (“SMP”) to support the planned North Terminal Expansion project (the “Project”) at the Patrick Leahy Burlington International Airport located in South Burlington, Vermont (the “Airport”). VHB understands that current design plans for the Project will require substantial soil disturbance north of the existing terminal (the “Project Area”) to support installation of an approximately 27,000 square-foot building. The Project Area coincides with a former fuel storage and transfer area that has been associated with numerous environmental investigations to evaluate the nature and extent of petroleum impacts to soil, groundwater, and soil vapor (see Section 1.2). In 2018, the Airport received a Sites Management Activity Complete (“SMAC”) designation for the former fuel storage and transfer area from Vermont Department of Environmental Conservation (“DEC”); however, residual petroleum impacts remain in soil, groundwater, and soil vapor at the Project Area. In accordance with §35- 804(a)(3) of DEC’s Investigation and Remediation of Contaminated Properties Rule (“IRule”) dated February 23, 2024, a SMP will be required for the Project considering the Project Area is associated with a SMAC designation and residual soil impacts may be encountered. 1.1 Site Description The Airport (SPAN: 600-188-10911) is owned by the City of Burlington and is located at 1200 Airport Drive, South Burlington, Vermont. The approximate center of the Airport is located at 44.4707483134606 latitude and -73.151630768513 longitude. The Project Area overlaps a former fuel storage and transfer area that is currently used as an airplane loading and unloading area. The Project Area’s location and surroundings are shown in Figure 1. The Project Area is bounded to the west and south by an existing Airport terminal, a control tower to the north, and the Airport runway apron to the east. Residential properties are located approximately 2,000 feet to the southwest of the Project Area. The topography of the Project Area and surrounding area at the Airport is flat. The nearest surface water is an unnamed tributary of the Winooski River, located approximately 2,500 feet to the northwest of the Project Area; the Winooski River is located approximately 4,500 feet to the north of the Project Area. A Site Vicinity Map is provided as Figure 2. 1.2 Previous Investigations Subsurface petroleum contamination was initially discovered in soil and groundwater at the Airport in 1993 during a fuel farm relocation study. The former fuel farm was designated by the DEC Sites Management Section (“SMS”) as hazardous site #931503 due to the identification of petroleum contamination resulting from releases from underground storage Soil Management Plan 2 Introduction and Background tanks (“USTs”) and aboveground storage tanks (“ASTs”). The results of the 1993 Initial Site Investigation report prepared by Ground Water of Vermont (“GWV”) identified two petroleum plumes in groundwater and associated soil vapor impacts suggesting releases had occurred from a jet fuel UST and abandoned gasoline USTs (GWV, 1994). Supplemental investigation activities were conducted by EMCON in 1996 to better define the extent of contamination; this supplemental investigation identified impacts to soil and groundwater along with the detection of light non-aqueous petroleum liquids (“LNAPL”) within a groundwater monitoring well (EMCON, 1996). The lateral extent of petroleum contamination in soil and groundwater was not fully delineated during the 1996 supplemental investigation; however, the extent of the LNAPL was delineated (EMCON, 1996). In 1998, four USTs (one 6,000-gallon aviation gasoline UST, two 10,000-gallon jet fuel USTs, and one 12,000-gallon jet fuel UST) and three petroleum ASTs were removed from the former fuel farm (SMS, 2018). A peak photoionization detector (“PID”) screening value of 160 parts per million (“ppm”) was recorded in the tank grave of the former 10,000-gallon jet fuel USTs and an oily sheen was observed on groundwater (SMS, 2018). The fuel farm was decommissioned in 1998 following the removal of all USTs and ASTs. Groundwater monitoring was conducted to document the progress of natural attention of the dissolved phase groundwater contamination. Additional soil borings and groundwater monitoring wells were installed in 2017 to further define the extent of contamination. The 2017 investigation indicated that subsurface contamination resulting from releases from the former tanks is confined to the fuel farm area and is not migrating off-site (SMS, 2018). Although residual contamination is present in groundwater and soil at the fuel farm area, contamination concentrations are stable, declining, and not migrating (SMS, 2018). Therefore, DEC SMS assigned a SMAC designation to the former fuel farm which served as a Notice to the Land Record documenting that residual contamination is present in soil, soil vapor, and groundwater. The locations of the former USTs and former ASTs within the Project Area are depicted on Figure 3. 1.3 Soil Management Objectives The objective of this SMP is to prescribe how contaminated soil shall be managed, tracked, and isolated during and following Project activities. Therefore, the purpose of implementing this SMP is to monitor that the contaminated soil that is disturbed within the Project Area is managed appropriately (either on-site or off-site), does not migrate, does not present a risk to potential sensitive receptors during or after Project activities, and is isolated on-site beneath an engineered barrier following redevelopment. As a result of the known residual petroleum contamination associated with the former fuel farm and to achieve the soil management objectives, VHB proactively evaluated soil quality in the Project Area to depths that are anticipated to be excavated during the Project (see Section 2). 1.4 Redevelopment and Reuse Plan It is anticipated that soil management activities will occur concurrently with the Project. The design plans for the Project include the installation of an approximately 27,000 square-foot Soil Management Plan 3 Introduction and Background building north of the existing terminal which will require disturbance and management of soil. As a result of the known residual petroleum-impacted soil and possible presence of uncharacterized contaminants, VHB proactively sampled soil that was anticipated to require excavation during the Project; the details and results of this pre-characterization investigation are presented in Section 2 and are incorporated into the SMP. VHB understands that Jacobs preliminarily anticipates approximately 6,800 cubic yards (“CY”) of material would require excavation to support construction of the Project. Due to the planned construction activities, it is estimated that 50% of the excavated volume would be replaced; therefore, Jacobs anticipates approximately 3,000 CY of soil would require management and off-site reuse or disposal at a certified landfill, depending on soil quality. Current building foundation design plans are shown in Appendix A. Additionally, given the known presence of residual petroleum impacts to soil, groundwater, and soil vapor associated with the former fuel farm located within the footprint of the proposed North Terminal building, a vapor mitigation system will be proactively incorporated into the building design (see Appendix B). 1.5 Regulatory Requirements 1.5.1 Compliance with DEC IRule This report meets the requirements of a SMP in accordance with the DEC IRule. 1.6 Performance Standards 1.6.1 Achieving Soil Management Plan Objectives The SMP objectives will be accomplished by the following: 1. Establishing and documenting adherence to procedures for soil inspection, classification, management, disposal, and monitoring so that the impacted material is managed appropriately and does not migrate or present undue an exposure risk to construction workers or the public during construction activities; 2. Excavation and documentation of potential off-site disposal of soil impacted with volatile organic compounds (“VOCs”) and semi-VOCs (“SVOCs”) at concentrations greater than the Resident Vermont Soil Standards (“VSS”) and/or Non-Resident VSS and polycyclic aromatic hydrocarbons (“PAHs”) expressed as expressed as benzo(a)pyrene toxicity equivalence factor (“BaP-TEQ”) at concentrations greater than the DEC Urban Background Soil Concentration; 3. The proactive design and installation of a vapor mitigation system concurrent with Project construction activities, as well as the collection of indoor air samples following construction. Indoor air samples will be collected to identify if indoor air is impacted by VOCs (see Section 8.1). These indoor air sampling results will be used to inform if SSDS operation and post-remedy monitoring will be needed to mitigate vapor intrusion risks (as described in Section 8.2); and Soil Management Plan 4 Introduction and Background 4. Installing, maintaining, and documenting an engineered barrier over soil that will be left in place with VOC and SVOC concentrations greater than the Non-Resident VSS. 1.6.2 Soil Standards The use of the Project Area is a commercial airport terminal building. Therefore, the applicable soil standards for this Project are the Non-Resident VSS presented in the IRule. For analytes with no Non-Resident VSS, the applicable soil standard will be the U.S. Environmental Protection Agency (“US EPA”) Industrial Regional Screening Levels (“RSLs”). As required by DEC, PAH data were normalized by calculating the BaP-TEQ for each soil sample where PAH analysis was performed. The BaP-TEQ is calculated by summing the product of the detected concentrations for each of the PAHs with the corresponding BaP toxicity equivalence factor (“TEF”). The Project is located within an Urban Background Area per the Vermont Agency of Natural Resources (“ANR”) Natural Resource Atlas. 1.6.3 Compliance Points A discussion of the soil borings and sample locations that were used to characterize the in- place soil, including maps and a justification for these compliance points, are discussed in Section 1.2 and Section 3.2.1, and the results of VHB’s soil pre-characterization investigation are presented in Section 2 and shown on Figure 4. 1.7 Project Contacts Contact information for Project stakeholders is included in Table 1 below, as well as contact information for proposed contractors and subcontractors for the corrective action activities.

Details specific to the investigation of the Project Area are provided in the following sections. In accordance with the SMAC letter, DEC SMS was notified by VHB prior to conducting any subsurface work at the Project Area. The soil pre-characterization investigation was conducted in accordance with VHB’s Scope of Work for Soil Characterization and Corrective Action Planning for the North Terminal Expansion Project, dated December 21, 2023, that was reviewed by DEC. 2.1 Utility Clearance / Locating Survey Prior to conducting intrusive subsurface activities at the Project Area, the work areas were cleared for subsurface utilities by DigSafe®. VHB also retained an underground locating company, Button Underground Locating (“Button”) to conduct a magnetometer and Ground Penetrating Radar (“GPR”) survey at the Project Area. The results of the survey were used to place soil borings at locations that were unlikely to encounter subsurface utilities or obstructions. 2.2 Coring of Asphalt and Concrete The ground surface of the Project Area was covered with an aircraft tarmac comprised of approximately 15-thick concrete apron overlying 4-inches of bituminous pavement. Therefore, VHB retained VT Concrete Cutting & Concrete Solutions to pre-core through the asphalt and/or concrete at the locations of the proposed soil borings prior to drilling activities. The 4-inch diameter cores ranged in thickness from approximately 5-inches to 21-inches. Approximately 6-inches of crushed aggregate sub-base was observed underlying the asphalt and/or concrete at the Project Area. The cores were placed back into the respective holes in order to match the existing surface of the tarmac until drilling activities were completed. Following completion of drilling activities, the removed cores were transported to Myers Container Service Corp. in Colchester, VT for recycling. 2.3 Soil Pre-Characterization Sampling 2.3.1 Methodology On February 5th and 6th, 2024, a licensed driller from Eastern Analytical, Inc. (“EAI”) with VHB oversight, advanced a total of 40 soil borings (SB-1 through SB-40) to screen and sample Project Area soils (see Figure 3). The soil borings were advanced as follows: Soil Management Plan 7 Soil Pre-Characterization Investigation 1) Targeted Soil Sampling - A total of 27 soil borings (SB-1 through SB-27) were advanced at targeted locations where known petroleum releases were reported by prior environmental investigations and within the approximate footprint of each of the former ASTs/USTs to better understand the quality of soil impacted by historical petroleum releases or prior subsurface features (UST or piping) that had the potential to cause a release. 2) Soil Sampling Outside of UST/AST and Known Release Areas - A total of 13 soil borings (SB-28 through SB-40) were advanced outside of the former fuel storage area to better understand soil quality at spatially representative locations within the Project Area. All 40 soil borings were advanced using a Geoprobe direct-push drill rig to depths of approximately 6 feet below ground surface (“fbgs”), the maximum anticipated depth of excavation during the Project. Continuous soil cores were collected in 4-foot intervals within dedicated butyrate liners from the 2-6 fbgs depth interval. VHB understands that the upper approximately 25-inches of the Project Area were excavated in 2019 as part of “Phase 4 of the Terminal Apron” project in order to install 15-inches of concrete over 4-inches of bituminous pavement and 6-inches of crushed aggregate sub-base. Therefore, VHB did not sample materials between the 0-2 fbgs depth interval considering that it is comprised of concrete, pavement, and crushed aggregate sub-base (circa 2019). After soil was extracted from each of the soil borings, soils were screened with a calibrated PID and visual/olfactory/geologic observations were recorded on boring logs that are provided in Appendix C. A decontaminated stainless-steel knife was used to make a small void along the length of soil core and the PID probe was immediately inserted into the void to screen the soil core for evidence of volatiles. Immediately following PID screening, discrete soil samples were collected directly into the appropriate laboratory-supplied sample containers. If evidence of petroleum impacts were observed (e.g., PID > 1 ppm above background, and/or visual/olfactory evidence), a discrete “Targeted Soil Sample” was collected from the depth interval associated with evidence of petroleum impacts and analyzed for VOCs, SVOCs and lead. If evidence of petroleum impacts were not observed at a soil boring location or depth interval, sub-samples were collected from the 2-4 fbgs and/or 4-6 fbgs depth intervals and composited by the laboratory for soil characterization as detailed in Section 2.3.1.1. All soil samples and sub-samples were transported in an ice-chilled cooler under chain of custody protocol to EAI’s laboratory in Concord, NH for analysis. After sampling, excess soil was returned to the borehole at the approximate depth from which it was sourced. The remainder of the soil boring was filled with driller-supplied bagged sand and the surface was repaired with concrete to match the surface elevation of the tarmac. All soil boring locations were measured with VHB’s sub-meter GPS. 2.3.1.1 Composite Soil Characterization Sub-samples samples collected from depth intervals at soil borings that were not associated with evidence of petroleum impacts during the field screening of soil core were composited by the laboratory to characterize larger areas of the Project Area where petroleum impacts Soil Management Plan 8 Soil Pre-Characterization Investigation were not identified (Grids 1 through 6, as shown on Figure 3). A total of eight composite samples were created by the laboratory at VHB’s request. The composite sample ID’s and their associated sub-samples are as follows: Grid 1 (2-4): SB-5 (2-4), SB-7 (2-4.5), SB-8 (2-4), SB-29 (2-4.5), and SB-30 (2-4) Grid 1 (4-6): SB-5 (4-6) and SB-30 (4-6) Grid 2 (2-4): SB-1 (2-4), SB-2 (2-4), SB-4 (2-4), and SB-37 (2-4) Grid 2 (4-6): SB-1 (4-6), SB-2 (4-6), SB-4 (4-6), and SB-37 (4-6) Grid 3 (2-4): SB-21 (2-4) and SB-38 (2-4) Grid 3 (4-6): SB-21 (4-6) and SB-38 (4-6) Grids 5/6 (2-4): SB-33 (2-4) and SB-35 (2-4) Grids 5/6 (4-6): SB-33 (4-6) and SB-35 (4-6) These eight composite samples were analyzed for VOCs, SVOCs, lead, and the five per- and polyfluoroalkyl substances (“PFAS”) compounds regulated by the State of Vermont. If analytical results for a given composite sample exceeded the applicable regulatory standard, the associated sub-samples were to be analyzed for the analytes associated with the exceedance reported in the composite sample to further refine the area that contributed to the exceedance in the composite sample. No exceedances of the Resident VSS or Urban Background Soil Concentration (PAHs and lead) were reported in the composite samples; therefore, no sub-samples were analyzed. 2.3.1.2 Waste Characterization Analysis Following review of laboratory analytical results for the discrete Targeted Soil Samples, soil samples associated with exceedances of the Resident VSS or Urban Background Soil Concentration (for PAHs and lead) were composited by the laboratory at VHB’s request and analyzed for the remaining waste characterization analyses typically required by regional landfills in order to establish disposal pre-approval from these potential receiving landfills. These composite samples were created from sub-samples that were located proximate to one another in order to pre-characterize each “release” area separately. As previously mentioned, the four waste characterization samples and their associated samples are as follows: Comp-Waste Char 1: SB-18 (5-6), SB-19 (5-6), and SB-27 (2.5-3.5) Comp-Waste Char 2: SB-24 (4-6) and SB-6 (5-6) Comp-Waste Char 3: SB-11 (4-6) SB-34 (2-3) These four waste characterization samples were analyzed for pesticides, herbicides, total petroleum hydrocarbons (“TPH”), reactivity, corrosivity, ignitability, polychlorinated biphenyls (“PCBs”), Resource Conservation and Recovery Act (“RCRA”) 8 metals (excluding lead as the sub-samples were already analyzed for lead), and the five PFAS compounds regulated by the State of Vermont. Soil Management Plan 9 Soil Pre-Characterization Investigation Soil samples were submitted for analysis of one or more of the following analytical methods as discussed in the prior sections: VOCs by EPA Method 8260, SVOCs by EPA Method 8270E, PFAS by EPA Method 537 modified, Pesticides by EPA Method 8081B, Herbicides by EPA Method 8151, TPH by EPA Method 8100 L1, Reactive Cyanide and Reactive Sulfide by EPA Method 7.3.3.2, Corrosivity by EPA Method 9045D, Ignitability by EPA Method 1030, and/or PCBs by EPA Method 8082A using Soxhlet extraction. 2.4 Results Soils encountered at the Project Area generally consisted of fine sand with trace gravel. PID screening values ranged from background levels to 211.9 ppm. Background screening values ranged from 0.0 ppm to 0.8 ppm. Petroleum odors were noted in 13 of the 40 soil borings; odors were noted only in the Targeted Soil Sampling soil boring locations and were not noted in the Soil Sampling Outside of UST/AST and Known Release Areas soil boring locations. Analytical results are summarized in the following sections and in Table 2 and Figure 4. Waste characterization analytical results are summarized in Table 3. Descriptions of soil cores and PID screening values are included in Appendix C. Laboratory analytical reports are included as Appendix D. 2.4.1 Targeted Soil Sampling Lead was not reported in any of the collected soil samples at concentrations exceeding the Resident VSS of 41 mg/kg. The soil samples collected from the 4-6 fbgs depth interval at SB-11 and SB-24 and from the 5-6 fbgs depth interval at SB-6 contained the VOC analyte naphthalene at concentrations exceeding the Resident VSS of 1.2 mg/kg, but less than the Non-Resident VSS of 7.2 mg/kg. The soil samples collected from the 2.5-3.5 fbgs depth interval at SB-27 and from the 5-6 fbgs depth interval at SB-18 and SB-19 contained the VOC analyte naphthalene at concentrations exceeding the Non-Resident VSS of 7.2 mg/kg. The soil sample collected from the 5-6 fbgs depth interval at SB-18 contained the SVOC analyte 1-methylnaphthalene at a concentration exceeding the Resident VSS of 18 mg/kg, but less than the Non-Resident VSS of 73 mg/kg. The soil samples collected from the 2.5-3.5 fbgs depth interval at SB-27, the 4-6 fbgs depth interval at SB-11 and SB-24, and the 5-6 fbgs depth interval at SB-19 contained the SVOC analyte naphthalene at concentrations exceeding the Resident VSS of 1.2 mg/kg, but less than the Non-Resident VSS of 7.2 mg/kg. The soil sample collected from the 5-6 fbgs depth interval at SB-18 contained the SVOC analyte naphthalene at concentrations exceeding the Non-Resident VSS of 7.2 mg/kg. The soil sample collected from the 3-4 fbgs depth interval at SB-20 contained PAHs (expressed as the BaP-TEQ) at a concentration exceeding the Resident VSS of 0.07 mg/kg, but less than the Urban Background Soil Concentration of 0.58 mg/kg. 2.4.2 Soil Sampling Outside of UST/AST and Known Release Areas Lead, PFAS, and VOCs were not reported in the soil samples at concentrations exceeding their respective Resident VSS or Urban Background Soil Concentration (lead). Soil Management Plan 10 Soil Pre-Characterization Investigation The soil sample collected from the 3-4 fbgs depth interval at SB-40 contained PAHs (expressed as the BaP-TEQ) at a concentration exceeding the Resident VSS of 0.07 mg/kg, but less than the Urban Background Soil Concentration of 0.58 mg/kg. The soil sample collected from the 2-3 fbgs depth interval at SB-34 contained PAHs (expressed as the BaP-TEQ) at a concentration exceeding the Urban Background Soil Concentration of 0.58 mg/kg, but less than the applicable Non-Resident VSS of 1.54 mg/kg. 2.4.2.1 Composite Soil Samples Lead, PFAS, and VOCs were not reported in the soil samples at concentrations exceeding their respective Resident VSS or Urban Background Soil Concentration (lead). The two composite soil samples Grid 3 (2-4) and Grid 3 (4-6) reported PAHs (expressed as the BaP-TEQ) concentrations exceeding the Resident VSS of 0.07 mg/kg, but less than the Urban Background concentration of 0.58 mg/kg. 2.4.3 Waste Characterization Soil Samples PFAS, Herbicides, Pesticides, TPH, and PCBs were not reported in the waste characterization soil samples at concentrations exceeding their respective Resident VSS. Soil Management Plan 11 Conceptual Site Model 3 Conceptual Site Model 3.1 Site History The Airport has been operating since the 1930’s. The former fuel farm (located within the Project Area) at the Airport was used for the storage of fuel and deicing fluids to support aviation operations (Jet-A aviation fuel, aviation gasoline, unleaded gasoline, diesel, ethylene glycol) and was reportedly active since the 1950’s (GWV, 1994). In 1998, the former fuel farm was decommissioned when the remaining tanks were removed from the area and currently is used as an airplane loading and unloading area (SMS, 2018). Based on historical reports, groundwater at the Site has been encountered at a depth of approximately 12 fbgs and appears to be flowing in a southwesterly direction (GWV, 1994). The Airport is located within a broad, flat topographic high area resulting in a low horizontal groundwater gradient (SMS, 2018). Soils at the Project Area and in the surrounding area are mapped on the ANR Natural Resource Atlas as Adams and Windsor loamy sands (ANR, 2024). Prior investigations have described soils as fine sands and various amounts of silt, with trace gravel. Soils encountered at the Site during VHB’s February 2024 investigation generally consisted of fine sands with trace gravel. Based on information provided by Hoyle, Tanner and Associates, Inc., VHB understands that the upper approximately 25-inches of the Project Area were excavated in 2019 and subsequently replaced with 15-inches of concrete overlying 4- inches of bituminous pavement and 6-inches of crushed aggregate sub-base. 3.2 Site Contamination 3.2.1 Previous Investigations Reported releases of gasoline and jet fuel to soil and groundwater were identified during prior environmental assessments at the Site. The former fuel farm was designated by the DEC SMS as hazardous site #931503 due to the identification of petroleum contamination to soil, groundwater, and soil vapor resulting from releases from USTs and ASTs. A summary of the former storage tanks at the former fuel farm and associated releases is included in Table 4 (GVW, 1994; EMCON, 1996; and SMS, 2018). The locations the former storage tanks are depicted on Figure 3. The DEC SMS assigned the former fuel farm a SMAC designation based on the results of prior environmental investigations that identified petroleum contamination concentrations are stable, declining, and not migrating (SMS, 2018). The SMAC letter serves as a Notice to the Land Record documenting that residual contamination remains at the former fuel farm in soil and groundwater. Due to the presence of residual petroleum contamination in soil and groundwater, there is the potential for soil vapor impacts at the Project Area. Soil Management Plan 12 Conceptual Site Model 3.2.2 Pre-Characterization Soil Sampling VHB’s pre-characterization sampling evaluated soil quality in the Project Area to depths that are anticipated to be excavated during the Project. The following contamination was identified during the pre-characterization soil sampling: The VOC and SVOC analyte naphthalene was identified in deeper soils (4-6 fbgs) at multiple locations in exceedance of the Resident VSS and/or Non-Resident VSS within the Project Area; naphthalene was identified in shallow soil (2.5-3.5 fbgs) at one location in exceedance of the Non-Resident VSS. The SVOC analyte 1-methylnaphthalene was identified in deeper soil (4-6 fbgs) at one location in exceedance of the Resident VSS within the Project Area. These naphthalene and 1-methylnaphthalene impacts were only reported at the Targeted Soil Sampling soil boring locations and therefore are likely contributable to releases from the former petroleum storage tanks at the Project Area. The naphthalene and 1- methylnaphthalene impacts were reported in soil samples collected at a fuel transfer area and within the vicinity of the following former storage tanks: Innotech 1, Innotech 2, Innotech 5, and Abandoned UST (see Table 4). PAHs (expressed as the BaP-TEQ) were identified in shallow soil at one location in exceedance of the DEC Urban Background Soil Concentration at the south end of the Project Area. The isolated PAH exceedance may be associated with atmospheric deposition of aircraft and support vehicle exhaust prior to paving of this area. 3.3 Sensitive Receptors and Potential Exposure Pathways The main exposure pathways associated with impacted soil and groundwater at the Project Area would be through direct contact or ingestion of impacted media. The impacted soils are isolated beneath 15-inches of concrete overlying 4-inches of bituminous pavement and 6- inches of crushed aggregate sub-base. Based on the presence of a paved isolation barrier and the Project Area’s current use as an airplane loading and unloading area, it appears that the potential exposure risks to sensitive receptors associated with these shallow soil impacts are currently low. Any soil contamination to be left in place (further described in Section 6.1) will be isolated by an engineer barrier. Based on prior data it does not appear that contaminated groundwater is migrating off-site and no public drinking water wells are reportedly located at the Airport; therefore, there does not appear to be a direct exposure or ingestion risk to impacted groundwater at the Project Area. The main exposure pathway associated with potentially impacted soil vapor at the Project Area would be through inhalation. The associated risks of potential vapor intrusion in the planned North Terminal Expansion building can be adequately mitigated via a SSDS, which has proactively been included in the Project plans and will be addressed during implementation of this SMP (see Appendix B). This SSDS will only be activated if confirmatory indoor air sampling (see Section 6.2.2) results collected from within the new building identifies an exceedance of the applicable Non-Resident Indoor Air Standard (“IAS”) suggesting a vapor intrusion risk exists. Soil Management Plan 13 Quality Assurance / Quality Control Measures 4 Quality Assurance / Quality Control Measures Field screening, sample collection and laboratory analysis activities were conducted in accordance with the Soil Pre-Characterization Sampling Plan. Quality assurance (“QA”) and quality control (“QC”) measures were adhered to during the investigation. All samples adhered to laboratory sample acceptance policies; and laboratory analytical QA/QC criteria are included with the attached laboratory reports. No data were rejected due to improper collection techniques, sample delivery issues, hold times or laboratory analytical procedures. 4.1 Elevated Detection Limits The laboratory detection limits for VOC analytes 1,2,3-trichloropropane and 1,2-dibromo-3- chloropropane and SVOC analytes benzidine, n-nitrosodimethylamine, and n-nitrosodi-n- propylamine in all soil samples exceeded the respective State or EPA regulatory standards. The laboratory detection limits for VOC analytes 1,2-bibromoethane, 1,2-dichloroethane, bromodichloromethane, chloroform, vinyl chloride in soil samples SB-13 (2-3), SB-18 (5-6), SB- 19 (5-6), and SB-27 (2.5-3.5) exceeded the respective State or EPA regulatory standards; these four soil samples were reported with a dilution factor. Laboratory detection limits are statistically calculated values and are the lowest level that can be reported. Due to the extremely low standards for the aforementioned VOC and SVOC analytes and limits of the 8260 and 8270E methods, the laboratory could not resolve concentrations (or lack thereof) of these analytes below the reported laboratory detection limits. 4.2 QA/QC Conclusions As discussed in Section 4.1, the elevation of laboratory detection limits to concentrations greater than the respective regulatory standards for select analytes in soil samples occurred; however, these compounds were not considered contaminants of potential concern and were not detected in other soil samples at concentrations greater than laboratory reporting limits. Thus, the elevated soil detection limits do not change the conclusions of this report. Based on these conclusions, the analytical data for the project are deemed useable, accurate and complete for the purposes of this report. 4.3 Data Gaps The Soil Pre-Characterization Sampling Plan was followed by VHB with assistance from the subcontractors Button, VT Concrete Cutting & Concrete Solutions, and EAI. No data gaps associated with field screening, sample collection, and/or laboratory analysis activities have been identified as of the date of this report. Soil Management Plan 14 Soil Pre-Characterization Conclusions 5 Soil Pre-Characterization Conclusions In February 2024, VHB conducted a pre-characterization investigation of soil at the Project Area. Based on field observations and analytical data collected during this investigation, VHB provides the following conclusions: Targeted Soil Sampling A total of 26 discrete soil samples that were collected from soil borings and depth intervals associated with evidence of petroleum impacts were submitted for laboratory analysis for VOCs, SVOCs, and lead. Lead was not detected in exceedance of the Urban Background Soil Concentration in all 26 soil samples analyzed. Select petroleum VOCs were reported in exceedance of the Resident VSS in three soil samples [SB-6 (5-6), SB-11 (4-6), and SB-24 (4-6)] and in exceedance of the Non-Resident VSS in three soil samples [SB-18 (5-6), SB-19 (5-6), and SB-27 (2.5-3.5)]. Select petroleum SVOCs were reported in exceedance of the Resident VSS in five soil samples [SB- 11 (4-6), SB-18 (5-6), SB-19 (5-6), SB-24 (4-6), and SB-27 (2.5-3.5)] and in exceedance of the Non-Resident VSS in one soil sample [SB-18 (5-6)]. PAH concentrations (expressed as the BaP- TEQ) were reported in exceedance of the Resident VSS, but less than the Urban Background Soil Concentration, in two soil samples [SB-20 (3-4) and SB-40 (3-4)]. Soil Sampling Outside of UST/AST and Known Release Areas A total of eight soil samples and one discrete sample were submitted for laboratory analysis for VOCs, SVOCs, lead, and PFAS as regulated by the State of Vermont in order to characterize portions of the Project Area that were not associated with petroleum impacts. Lead, PFAS, VOCs, and non-PAH SVOCs were not detected in exceedance of the Resident VSS in all eight composite soil samples analyzed. PAH concentrations (expressed as the BaP-TEQ) were reported in exceedance of the Resident VSS, but less than the Urban Background, in two composite soil samples [Grid 3 (2-4) and Grid 3 (4-6)]. PAH concentrations (expressed as the BaP-TEQ) were reported in exceedance of the Urban Background, but less than the Non- Resident VSS, in one soil sample [SB-34 (2-3)]. A soil sample collected from the 4-6 fbgs depth interval at SB-34 did not report PAH concentrations (expressed as the BaP-TEQ) in exceedance of the Resident VSS. Waste Characterization Soil Samples Discrete soil samples that contained analytes at concentrations exceeding the Resident VSS were composited by the laboratory and analyzed for the remaining analyses required to establish pre-approval from potential receiving landfills. A total of four waste characterization samples were analyzed for PCBs, PFAS, RCRA 8 metals, pesticides, herbicides, TPH, reactivity, corrosivity, and ignitability. These analytes did not exceed the Resident VSS in any of the waste characterization samples. Soil Management Plan 15 Remedial Construction Plan 6 Remedial Construction Plan 6.1 Impacted Soil After construction of the Project is complete, soil with concentrations of VOCs and SVOCs above the Resident VSS and/or Non-Resident VSS and PAHs (expressed as BaP-TEQ) above the DEC Urban Background Soil Concentration may remain on-site. To mitigate the potential risk of exposure to and possible migration through the erosion of this impacted soil, a remedial system will be constructed consisting of an engineered isolation barrier. In general, the engineered isolation barrier will include a concrete building slab or concrete/bituminous aircraft apron consisting of concrete and/or bituminous pavement and appropriately-sourced sub-base material over indicator material. The indicator material will consist of a non- biodegradable material that distinguishes the divide between remaining contaminated soil and overlying clean soil/engineered isolation barrier. Examples of an acceptable indicator material include geotextile fabric, geo-grid type fabric, orange plastic snow-fencing, etc. The engineered isolation barrier details specific to each type of anticipated surface completion at the Project are included in Table 5 below. Table 5 – Proposed Isolation Barriers Surface Completion Type Isolation Barrier Description (All layers to be included, listed from surface to depth) Impervious Surface Concrete Building Slab 6” Concrete Minimum of 20 mil vapor barrier Minimum of 8” crushed stone Minimum of 10 mil vapor barrier Indicator material* Concrete Aircraft Apron 15” Concrete 4” Bituminous concrete pavement 6” Crushed stone Indicator material* Bituminous Pavement 4” Bituminous concrete pavement 6” Crushed stone Indicator material* * Indicator Material is a non-biodegradable permeable material (e.g.: geotextile fabric, orange plastic construction safety fencing, or similar) that will distinguish the interface between the imported fill/backfill and the impacted soil below. Soil Management Plan 16 Remedial Construction Plan 6.2 Installation of Sub-Slab Depressurization System (SSDS) As previously mentioned, residual petroleum contamination in soil and groundwater are documented at the Project Area resulting in the potential for soil vapor impacts. Therefore, the project design engineer has proactively included the installation of an SSDS during construction of the proposed building foundation. This SSDS will only be activated if confirmatory indoor air sampling (see Section 6.2.2) results collected from within the new building identifies an exceedance of the applicable Non-Resident IAS suggesting a vapor intrusion risk exists. 6.2.1 Sub-Slab Depressurization System Design The purpose of the SSDS (if activated) would be to intercept vapor that might off-gas from residual contaminated groundwater in order to mitigate the risk of impacted soil vapor from adversely impacting indoor air. The SSDS has been conservatively designed to encompass the entire proposed building footprint and will be installed prior to or during construction of the building foundation. The SSDS design and proposed location of the SSDS are provided in Appendix B. The SSDS will consist of a vapor retarder that will be placed on the graded native soil with the edges of the vapor retarder sheeting not sealed or overlapping. The purpose of this vapor retarder is to limit air, to the extent practical, from the sub aggregate layer into the conveyance layer. A stone bed, consisting of coarse gravel, and horizontal piping will be placed on top of the vapor retarder to create a porous network for soil vapor to be drawn toward the piping. A second vapor barrier will be installed above the stone bed, and below the proposed concrete slab. The edges of this vapor barrier will be sealed to one another and to the edges of the building foundation wall to create an air-tight seal. The piping will penetrate up through the vapor barrier and concrete slab and will be routed up through the roof of the building. In the event that confirmatory sampling of indoor air following construction (see Section 6.2.2) confirm petroleum impacts to indoor air are present an adequately sized blower/fan will be installed on the roof to continuously apply a vacuum to the sub-slab environment, expelling the sub-slab soil vapor. Following activation of the SSDS (if needed, see Section 8) a technician will perform an initial inspection of the SSDS to evaluate the effectiveness of the vacuum. 6.2.2 Indoor Air Quality Confirmation Sampling Following Project construction, VHB will collect indoor air samples to evaluate the condition of indoor air within the lowest level of the new structure to evaluate if petroleum contaminated soil vapor is impacting indoor air within the new building. If these sampling events do not suggest indoor air within the lowest level of the new building is impacted, the SSDS will not be activated but shall remain in place to protect indoor air passively. Additional details associated with the indoor air sampling are provided in Section 8.1. Soil Management Plan 17 Waste Management Plan 7 Waste Management Plan 7.1 Soil Soil pre-characterization samples were collected during VHB’s February 2024 investigation from depths and locations that were anticipated to require excavation based on design plans (see Section 1.4). These soil data identified contaminants (VOCs and SVOCs) at concentrations that exceeded the applicable regulatory standards listed in Section 1.6.2. 7.1.1 Soil Management Categories Soil impacted with VOCs and/or SVOCs at concentrations exceeding the Non-Resident VSS will be excavated during the Project. The management options for Project Area soil are dependent on the associated VOC and/or SVOC concentrations at particular locations within the Project Area. For the purpose of the Project, soil is classified as one of four “Soil Types” as described below: 1) Soil Type RED Hatch: Depicted with red shading in Figures 5a and 5b. This soil has concentrations of petroleum-related contaminants (naphthalene and/or 1-methylnaphthalene) exceeding the Resident VSS and in some instances the Non- Resident VSS. The applicable cleanup standard for the Project Area is the Non- Resident VSS; however, based on correspondence with Jacobs and the Airport, VHB assumes that petroleum-impacted soil associated with exceedances of the Resident VSS will be disposed of offsite if excavated. Therefore, petroleum-impacted soil associated with exceedances of the Resident VSS are referred to as Soil Type RED Hatch in the following sections and depicted as Soil Type RED Hatch in Figures 5a and 5b. o Onsite Reuse: this material may remain on-site if undisturbed and buried under an IRule-compliant engineered isolation barrier (see Section 6.1). o Offsite Reuse: this material must be disposed of at an appropriately-licensed waste disposal facility. 2) Soil Type RED: Depicted with red shading in Figure 5a. This soil has concentrations of PAHs (expressed as BaP-TEQ) at concentrations exceeding the DEC Urban Background Soil Concentration of 0.58 mg/kg, but less than the Non-Resident VSS and no other contaminants at concentrations exceeding their Resident VSS. Soil Management Plan 18 Waste Management Plan o Onsite Reuse: this material may be reused onsite in an unencumbered manner. Isolation under an engineered isolation barrier is not required (see Section 7.1.3.1). o Offsite Reuse: this material must be disposed of at an appropriately-licensed waste disposal facility (see Section 7.1.3.2). 3) Soil Type YELLOW: Depicted with yellow shading in Figures 5a and 5b. This soil has reported PAH concentrations (expressed as BaP-TEQ) above the Resident VSS of 0.07 mg/kg, but below the DEC Urban Background Soil Concentration of 0.58 mg/kg and no other contaminants were detected at concentrations exceeding the Resident VSS. This soil is not regulated by the DEC as long as it remains in an Urban Area as defined by the ANR Natural Resources Atlas. o Onsite Reuse: this material may be reused onsite in an unencumbered manner. Isolation under an engineered isolation barrier is not required (see Section 7.1.3.1). o Offsite Reuse: this material can be disposed at another property located within a Vermont Urban Area (see Section 7.1.3.2). 4) Soil Type GREEN: Depicted with green shading in Figures 5a and 5b. This soil has no reported contaminants at concentrations exceeding the Resident VSS. This soil is not regulated by DEC and can be reused in an unencumbered manner anywhere in the state of Vermont. o Onsite Reuse: this material may be reused onsite in an unencumbered manner. Isolation under an engineered isolation barrier is not required (see Section 7.1.3.1). o Offsite Reuse: this material may be reused offsite in an unencumbered manner within the State of Vermont (see Section 7.1.3.2). 7.1.2 Soil Inspection Soil Types RED and RED Hatch During the excavation of Soil Type RED and RED Hatch, environmental observation will be provided by a qualified environmental professional (“QEP”) to document that proper soil management practices are being followed and to identify potential visual or olfactory evidence of environmental conditions that indicate the presence of contamination is greater than the petroleum impacts that were previously characterized. These conditions include significant staining, the presence of free-product, petroleum, strong olfactory evidence of contamination, or heavy presence of anthropogenic material or refuse. If these characteristics are observed, the QEP will also field screen this soil using a PID, and the soil will be stockpiled separately. If contamination is identified greater than the petroleum impacts that were previously Soil Management Plan 19 Waste Management Plan characterized, additional waste disposal characterization sampling prior to off-site disposal may be warranted. The QEP will notify the DEC Site Manager if the presence of contamination greater than the petroleum impacts that were previously characterized is identified and to confirm if additional characterization of this material is required. Based on the extensive dataset collected from the Project Area, it is not anticipated that these levels of impacts will be encountered. PID field screening of soil, if necessary, will be conducted as follows: at least three small depressions will be created in the soil being evaluated using a clean instrument and the PID probe will be inserted into each depression. The most elevated PID reading will be recorded. During construction, when the QEP is on-site, they will prepare a weekly report that will include the following: a description of the activities completed that week, weather, list of personnel on-site, field observations/readings and instrument calibration data. This weekly report will be submitted electronically to DEC, upon request. Soil Type YELLOW and GREEN If during the excavation of Soil Type YELLOW or GREEN the resident engineer or construction contractor identify environmental conditions that indicate the presence of contamination, such as staining, the presence of free-product, petroleum, or strong olfactory evidence of contamination, work will stop in that area until the on-call QEP observes the area. 7.1.3 Soil Management The purpose of these soil management procedures is to establish guidelines for segregating, tracking and documenting the excavation, loading, and stockpiling (if needed) of contaminated soil that is disturbed, to prevent the migration of contaminated soil during construction activities. Prior to excavation within areas of Soil Type RED and RED Hatch, soil type contaminant boundaries as illustrated in Figures 5a and 5b will be clearly identified and marked in the field by the contractor. During all stages of soil excavation within the Project Area, management, relocation, and/or disposal of each soil type, as defined in Section 7.1.1, the soil will be tracked and documented as necessary. Soil Type RED and RED Hatch, Occupational Safety and Health Administration (“OSHA”) Hazardous Waste Operations and Emergency Response (“HAZWOPER”) appropriately-trained personnel shall perform work related to handling these excavated soils under the supervision of a 40-Hour HAZWOPER- trained supervisor. A QEP will provide observation during excavation, loading and staging of these soils. During loading of Soil Type RED and RED Hatch for transport away from the excavation area and/or to an off-site disposal facility, the construction contractor will prevent migration of contaminated soil. This will be accomplished by verifying: There is no evidence of liquid leaking from the truck beds; Tailgates are latched; Soil Management Plan 20 Waste Management Plan Loads are covered (if necessary to prevent dust migration or if required for transport on public roads outside of the Property); There is no evidence of excavated soil on the truck exteriors; and, There is no evidence of excavated soil being tracked out of the excavation area. It is anticipated that Soil Type RED Hatch will be excavated and live-loaded for offsite disposal at an appropriate facility. Soil staging areas, if used for Soil Type RED and RED Hatch will meet the requirements of and be managed in accordance with the IRule 35-803(c)(1) which states the following criteria: The soil will be completely contained or encapsulated within a polyethylene plastic liner, which is a minimum thickness of 6 mils, and the integrity of the polyethylene liner will be maintained; The location of the soil staging areas will be: within the site; not within a 300-foot radius of a public water system (does not include buried water pipes or fittings) or potable water supply; not within 100 feet of a sensitive environment (i.e. stream, river, lake, pond, state or federally listed threatened or endangered species or habitat, wetland, floodplain, Class I or II groundwater, residence, or other similar area); and not within zone one or two of a groundwater source protection area; Public access to the soil staging areas will be prohibited; If the landowner of the property where the soil staging area is located is different from the soil generator, written approval (that also grants access for the Secretary), has been obtained before stockpiling begins; The location of the soil staging area is depicted on a site map; and, Failure to adequately maintain polyethylene-encapsulated soil piles will result in a new release subject to investigation and corrective action. Off-site soil staging areas, if used for Soil Type RED and RED Hatch will meet the requirements of and be managed in accordance with the IRule §35-803(d)(1) which states the following criteria: DEC will be notified of the contaminant concentrations and amount of soil that is to be transported to the off-site location; and, DEC will be provided with an ANR Atlas-generated map including the latitude and longitude of the exact location where the soil will be stockpiled, referenced to the WGS1984 coordinate system (Mercator), in decimal degrees. Minimum acceptable accuracy is plus-or-minus 15 feet. Prior to temporary stockpiling of contaminated soil (referred to as Soil Type RED and RED Hatch) that will be excavated during construction, the DEC Management of Non-Hazardous Contaminated Soil Request Form dated July 2021 (draft forms are provided in Appendix E) will be submitted to DEC and approved by DEC. Although, effort will be made by the contractor to “live-load” impacted soil onto transport trucks for off-site disposal, due to trucking availability or general project sequencing, the possibility exists that impacted soil from the Project Area may need to be temporarily staged during the Project, prior to on-site reuse or off-site disposal. To allow the contractor flexibility during construction, as part of this SMP, VHB requests DEC pre-approve the following alternative soil management procedures: Soil Management Plan 21 Waste Management Plan 1. Soil of similar category will be added to the appropriate soil stockpile as the Project progresses; 2. Soil piles will be uncovered for the duration of each work day when soil is added to the stockpile and will be covered overnight; 3. Soil piles will remain covered during the workday if a significant rain event is forecasted that could result in soil migration from the stockpile; 4. Considering the Project is anticipated to continue over several months, soil may be temporarily stockpiled for greater than 90 days; however, it is unlikely that soil will require stockpiling over winter, including between December 1 and April 1; and, 5. A QEP will regularly observe the stockpiles, document observations, and promptly make suggestions to the contractor to maintain or improve management protocols in order to mitigate the potential for soil migration. If during the observation, stockpile management procedures are observed to be inadequate and suggestions are made to improve the security of the stockpile, a supplemental observation will occur to confirm any deficiencies have been adequately addressed by the contractor. Soil Types YELLOW and GREEN Excavation, loading, and stockpiling of Soil Types YELLOW and GREEN will follow procedures outlined in the general erosion and sedimentation control plan for the Project. If Soil Type GREEN material is to be reused outside of an Urban Area (as defined by ANR Natural Resources Atlas) Soil Types YELLOW and GREEN will be segregated and managed separately. Soil Type YELLOW must remain within an Urban Area and the contractor is responsible for documenting where the material was taken. If Soil Type YELLOW and GREEN material are to be relocated by the contractor within an Urban Area, that material can be comingled as long as the contractor documents that the material remained in an Urban Area. 7.1.3.1 Soil Reuse Within Property Boundary Soil Type RED Hatch Soil Type RED Hatch associated with concentrations of petroleum-related compounds (naphthalene) exceeding the Non-Resident VSS may remain in place, undisturbed, if isolated under an engineered isolation barrier as described in Section 5. The location of Soil Type RED Hatch associated with concentrations of petroleum-related compounds exceeding the Non- Resident VSS remaining in place under the isolation barrier must be documented in the SMP Completion Report. Soil Type RED Hatch associated with concentrations of petroleum-related compounds (naphthalene and/or 1-methylnaphthalene) less than the Non-Resident VSS may remain in-place, undisturbed, and do not require burial beneath an isolation barrier. If Soil Type RED Hatch requires excavation it must be disposed of at an appropriately licensed facility (see Section 7.1.3.2). Soil Type RED This soil type may remain in place, undisturbed, or reused within the Project Area boundaries. Considering that the Project Area is located on parcel that is not zoned for residential or mixed-use, this material does not require isolation under an engineered isolation barrier. The Soil Management Plan 22 Waste Management Plan location of Soil Type RED remaining in place must be documented in the SMP Completion Report. Soil Type YELLOW and Soil Type GREEN may be prioritized for over-excavation to create room for Soil Type RED to be used as backfill on-site to potentially reduce the costly off-site disposal of Soil Type RED. Soil Type YELLOW This soil type is not regulated by DEC as long as it remains in an Urban Area as defined by the ANR Natural Resources Atlas. The Project boundaries are within an Urban Area; therefore, this soil can be reused on the Project Area, including as an isolation barrier. For Soil Type YELLOW that is reused on the Project Area, the approximate volume and relocation areas within the project boundaries should be tracked and documented by the resident engineer or construction contractor. If suitable (i.e., not gravel and cobble-rich) the excavated Soil Type YELLOW may be reused on-site to construct a portion of the engineered barriers. Soil Type YELLOW and Soil Type GREEN may be prioritized for over-excavation to create capacity for Soil Type RED to be used as backfill on-site; therefore, reducing the costly off-site disposal of Soil Type RED. Should Soil Type YELLOW be stockpiled on-site it will be stored separately from Soil Type RED and RED Hatch and Soil Type GREEN and labeled by the contractor so that inadvertent mixing of the various soil types does not occur. Soil Type GREEN This soil is not regulated by DEC, is considered clean, and can be reused in an unencumbered manner anywhere in the State of Vermont. Therefore, this soil can be reused on the Project Area at the discretion of the contractor. Tracking and documentation of transport and relocation of this soil is not required for the purposes of this SMP. 7.1.3.2 Soil Disposal Outside of the Property Boundary Soil Type RED and RED Hatch Based on the existing data, excess Soil Type RED and RED Hatch material that cannot be appropriately isolated on-site will require disposal at a certified landfill. Although a portion of the petroleum-impacted material described as Soil Type RED Hatch contains contaminants at concentrations greater than the Resident VSS but less than the Non-resident VSS and, therefore, could be reused onsite, it is VHB’s understanding that Jacobs and the Airport do not intend to reuse excavated soil impacted with petroleum-contaminants. Therefore, the volumes presented below assume that soil associated with concentrations of petroleum contaminants that exceed the Resident VSS that require excavation from the 2-6 fbgs depth interval will be disposed of offsite. Based on soil excavation estimates provided by Jacobs and the soil management areas depicted in Figures 5a and 5b that are based on analytical results generated during VHB’s 2024 pre-characterization of Project Area soil, approximately 200 CY of Soil Type RED (estimated in-place volume) and 550 CY of Soil Type RED Hatch (estimated in-place volume) within the 2-6 fbgs depth interval will require excavation at select locations and potential off- site disposal at a certified landfill should it be unable to be reused on-site. The volume of Soil Soil Management Plan 23 Waste Management Plan Type RED and RED Hatch to be excavated during the Project and require management may vary based on the following conservative assumptions: a) Should the final elevation of the new building be increased, or cut depths decreased, a significant volume of Soil Type RED and RED Hatch would no longer require excavation and potential off-site disposal. b) Imported structural sub-base will be installed beneath the new building and apron pavement. The sub-base thickness may be reduced should geotechnical data support use of on-site material as subbase and, therefore, volumes of Soil Type RED and RED Hatch requiring excavation would also be reduced. There are potential options/scenarios where volumes of Soil Type RED and RED Hatch requiring excavation and potential disposal could be significantly reduced. These options include: 1) determination that the existing on-site Soil Type RED material is suitable for reuse as backfill; 2) Soil Type YELLOW and Soil Type GREEN could be prioritized for over-excavation to create capacity for Soil Type RED to be used as backfill on-site; 3) reduce the proposed cut depth of the new building by raising the grade or reducing the thickness of proposed sub- base material. Soil load-out RED and RED Hatch On-road haul trucks will be loaded on-site and a QEP will provide observation of this process. Manifests, weigh slips, and truck inspection logs will be required to be tracked by the contractor and provided to the QEP. Additional soil management requirements are discussed in Section 7.1.3. Soil Type YELLOW This soil is not regulated by DEC as long as it remains in an Urban Area as defined by the ANR Natural Resources Atlas. Therefore, this soil can be disposed at another location within a Vermont Urban Area, as proposed and confirmed by the construction contractor. Based on engineering plans provided by Jacobs and the soil management areas depicted in Figures 5a and 5b that are based on analytical results generated during VHB’s 2024 pre- characterization of Project Area soil, approximately 1,200 CY of Soil Type YELLOW (estimated in-place volume) within the 2-6 fbgs depth interval will require excavation at select locations. As previously mentioned, should Soil Type YELLOW be stockpiled on-site it will be stored separately from Soil Type RED and RED Hatch and labeled so that inadvertent mixing of the various soil types does not occur. If excess Soil Type GREEN will be sent to the same “urban” location as Soil Type YELLOW, these two soil types can be co-mingled, otherwise the Soil Type GREEN material should be segregated. An off-site reuse location for Soil Type YELLOW has not been determined as this will be determined by the selected contractor. When off-site transportation of Soil Type YELLOW is required, the contractor will confirm the off-site reuse location is within an Urban Area as defined by the ANR Natural Resources Atlas. Soil load-out YELLOW Number of truckloads, approximate truckload volume, and the location where the material was taken (which must be in an Urban Area) will be tracked and documented by the resident engineer or construction contractor for the relocation of this soil outside of the Project Area. Soil Management Plan 24 Waste Management Plan A QEP will provide periodic observation of this process to check that Soil Type YELLOW being relocated to ANR-defined Urban Areas is consistent with what prior field screening and data suggested that designated this material as Soil Type YELLOW. Soil Type GREEN This soil is not regulated by DEC, is considered clean, and can be reused or disposed in an unencumbered manner anywhere in the State of Vermont. As stated previously the excavation and disposal of this Soil Type may be a useful and cost-effective technique to generate additional capacity to isolate more impacted Soil Types. Soil load-out GREEN Tracking and documentation of the transport and relocation of this soil is not required for the purposes of this SMP. 7.1.3.3 Visual Dust Monitoring The excavation of soil and contaminated soil has the potential to generate dust which could be a potential health hazard to workers and/or the public. Therefore, during excavation activities, visual dust monitoring will be performed by either the QEP, the construction contractor, or the resident engineer to mitigate this risk. During excavation of Soil Types RED, RED Hatch, YELLOW, and GREEN, ambient air monitoring will be performed for visible dust. Ambient air monitoring will consist of visual observations. If visual observations indicate visible dust, dust suppression techniques will be implemented, such as applying water on haul corridors, wetting equipment and excavation faces, restricting vehicle speeds, and covering excavated areas after excavation activity ceases. Work may continue with dust suppression techniques provided that visible dust generation is suppressed. Action should be taken to proactively mitigate dust generation should conditions conducive to dust generation be identified (e.g.: dry conditions, fine soils, wind, etc.). 7.2 Groundwater Depth to groundwater at the Project Area has been reportedly encountered at approximately 12 fbgs. Dewatering of the excavation is not anticipated since excavation depths are anticipated to be above the groundwater table. However, should dewatering be required to facilitate Project activities, groundwater will require management. Groundwater will be managed as potentially contaminated and will be containerized (i.e., frac tank, tote, 55-gallon drum, etc.) and a sample of the containerized groundwater will be collected to evaluate the disposal options. Should analytical results for the containerized groundwater sample identify an exceedance of the Vermont Groundwater Enforcement Standards (“VGES”), the containerized groundwater will require disposal at a treatment facility or potential treatment at a Waste Water Treatment Plant (“WWTP”). Should the analytical results of the groundwater sample identify no exceedances of the VGES, groundwater may be infiltrated in-place. Soil Management Plan 25 Waste Management Plan 7.3 Other Waste Materials During excavation activities, underground appurtenances and other unknown waste materials may be encountered. If the appurtenances or waste materials show no evidence of containing hazardous materials and there is no evidence of contamination, they will be removed (if required for Project activities) and properly disposed off-site. If the appurtenances or waste materials appear to be potentially hazardous (such as residual fuel in an abandoned pipe) or exhibit evidence of contamination such as significant staining, the presence of free-product or strong olfactory evidence of contamination, work will stop in the general vicinity of the appurtenance or waste materials until the on-call QEP observes the area. The QEP will observe and field screen the appurtenances or waste materials and adjacent soil using a PID and will notify the DEC Project contact. If the Project requires these materials to be excavated, they will be removed, poly-encapsulated and stockpiled separately for additional waste disposal characterization sampling prior to off-site disposal or a waste management contractor will be brought on-site to assess, remove and properly dispose of the potentially hazardous material (i.e.: asbestos containing material). Due to former use of the Project Area as a fuel farm, there is the potential to encounter an unanticipated abandoned UST. If a UST is encountered, work will stop in the general vicinity and the QEP will notify the DEC Site Manager and the DEC UST program will be notified. A waste management contractor will be brought on-site to remove and properly dispose of the encountered UST. If the waste meets the definition of a hazardous waste, it will be managed in accordance with the Vermont Hazardous Waste Management Regulations. If the waste contains PCBs at concentrations above 1 mg/kg it will be managed in accordance with the United States Environmental Protection Agency’s Toxic Substances Control Act (“TSCA"). If the waste does not meet either of these requirements, it will be disposed of in accordance with The State of Vermont Solid Waste Management rules. Again, given the available data this is not expected to be an issue during construction. Segregation, transport and off-site disposal of construction debris waste materials will be tracked and documented by the construction contractor. Segregation, transport and off-site disposal of impacted soil and hazardous waste materials will be tracked and documented by the construction contractor with observation from the QEP. Soil Management Plan 26 SSDS Post-Construction Requirements 8 SSDS Post-Construction Requirements 8.1 Confirmatory Indoor Air Sampling As previously discussed, prior to activating the SSDS, VHB will conduct one confirmatory indoor air sampling event to evaluate if subsurface petroleum impacts pose an unacceptable risk to indoor air within the new building at the Airport. During the sampling event, four indoor air samples will be collected from spatially-representative locations within the lowest level of the newly constructed building and an ambient air sample will be collected at a location that is outside and upwind of the building to distinguish potential background contaminant levels that may already be present in the ambient air at the Airport. These samples will be collected into batch certified 6-liter evacuated stainless steel canisters equipped with 8-hour flow controllers and will be positioned approximately 4-feet above the slab surface, to collect an air sample from the approximate breathing height of building occupants. The indoor air samples will be shipped to a certified laboratory under chain of custody protocol for analysis of VOCs by EPA TO-15. The indoor air analytical results will be compared to the Non-Resident IAS presented in the IRule. Should sample results suggest that the passive protections associated with the inactive SSDS (vapor barriers and passive venting) do not adequately mitigate vapor intrusion risks (i.e. report exceedance of the Non-Resident IAS), the SSDS should be activated, monitored, and maintained as outlined in the following Section. 8.2 System Operation and Maintenance Should indoor air sampling results indicate that the activation of the SSDS is required, a technician will perform an initial inspection of the system to evaluate the effectiveness of the vacuum. The activated SSDS will be equipped with a differential pressure gauge/alarm that will provide vacuum readings to monitor the pressure differential between the sub-slab air and the interior of the building. As outlined in the DEC Vapor Intrusion Guidance, dated March 24, 2020, a pressure differential greater than or equal to 2 pascals between indoor air and the sub-slab environment must be achieved for active vapor intrusion mitigation, and this differential must be demonstrated to be continuous throughout the year. As such, once the system is activated, SSDS monitoring shall be conducted monthly for the first year of operation and quarterly for subsequent years. During routine monitoring (if activated) the pressure differential readings shall be recorded. Should the pressure differential measurements recorded suggest that the SSDS is not operating as designed (i.e.: a positive pressure differential is recorded between the sub-slab and indoor air) or the system alarm is activated, the rooftop fan should be adjusted to apply Soil Management Plan 27 SSDS Post-Construction Requirements a stronger vacuum to the sub-surface or indoor air samples could be collected to demonstrate effective SSDS operation at pressures less than 2 pascals. After system activation, should the owner desire to assess whether the SSDS can be turned off and serve to protect the indoor air passively, sub-slab soil vapor samples could be collected at the Airport with the system deactivated. The sub-slab sample location(s) should be located above the area where petroleum impacts are the greatest based on the data generated from previous investigations at the Project Area. During sample point installation care should be taken to not pierce the vapor barrier. Should analytical results from the sub-slab soil vapor sampling indicate no exceedances of the applicable soil vapor standards, and DEC concurs that the SSDS no longer requires operation to mitigate potential indoor air impacts, sub-slab soil vapor sampling locations could be permanently sealed and the SSDS could be decommissioned or may remain in-place as a passive mitigation system should it be desired to be used again in the future. Soil Management Plan 28 Implementation Schedule 9 Implementation Schedule The Project and associated soil management activities are anticipated to commence during the Fall of 2024. This schedule is dependent on the selection of a contractor. The approved SMP will be provided to contractors bidding on the redevelopment work at the Property. A SMP Completion Report will be submitted to DEC for review within 90 days following completion of redevelopment work at the Airport. Soil Management Plan 29 Limitations 10 Limitations Although not part of the DEC SMP review process, this section has been included to describe the limitations of the information that was used to generate this SMP. This information is intended for the use of Jacobs for the specific purpose of outlining soil management activities for the North Terminal expansion project at the Airport in South Burlington, Vermont. No other uses, expressed or implied, are warranted. The design of this SMP was based on sound scientific techniques and experience with similar corrective actions. However, the recommended activities in this SMP are based on the available information. Should additional information become available pertaining to environmental concerns, VHB reserves the right to re-evaluate recommendations made herein. The recommendations in this report are based on information provided to VHB from the following sources: Jacobs; DEC; ANR; OBAR; Button; VT Concrete Cutting & Concrete Solutions; and EAI. Independent verification of the work performed by others was not always possible; therefore, its accuracy and reliability cannot be warranted.

Background OBAR Systems was retained by VHB to provide a design plan for the soil venting system to be installed at 1200 Airport Drive in South Burlington, Vermont in accordance with OBAR Systems December 15, 2023 New Construction Vapor Intrusion Mitigation System Design Quote. 2. General System Information The primary method for minimizing soil gas intrusion into a new building is to seal the concrete slab that is in contact with the soil and to provide a sub slab venting system that can be easily depressurized with a fan installed if necessary. The activated system is typically referred to as a Sub Slab Depressurization System (SSDS). The non-activated system is typically referred to as a Passive Venting System (PVS). An SSDS works by applying vacuum to the sub slab material and exhausting the soil gas from below the building to above the roofline. The system is comprised of PVC piping and Tees that are routed in the gravel bed under the lowest level concrete slab that is under occupied areas of the building. Solid PVC piping is routed from the sub slab piping to vertical pipes that run from below the slab up through the building to the roof. The exit point through the roof must be a minimum of 6 feet from the outside edge of the roof. The piping is routed to a location where a future venting fan can be installed outside the occupied portions of the building. If activation is necessary, the goal of the system is to be able to generate a negative pressure in the gravel bed that is greater than the negative pressures generated inside the building at the ground level. The following report meets the design metrics outlined in the ANSI/AARST CC-1000 Soil Gas Control Systems in New Construction of Buildings. Pipe diameters and coverage areas were determined based on the credit allowance for soil gas collection plenums. At a minimum, inspections are recommended to be performed at the following construction milestones to ensure compliance: - Lower vapor barrier installation - Sub slab fill and conveyance piping - Upper vapor barrier installation prior to concrete slab pour(s) - Above slab conveyance piping installation once through roof These inspections should be conducted by an individual who is trained and qualified for design of systems that comply with the ANSI/AARST CC-1000. 3. Sub Slab Fill In order for the system to function efficiently a continuous layer of ¾ inch AASHTO graded #57 stone with a minimum depth of 8" shall be installed below all building slabs in contact with the ground (AASHTO #57 coarse aggregate stone has 100% passing 1 1/2" screen, 95-100% passing 1" screen, 25-60% passing 1/2" screen, 0-10% passing #4 screen, and 0-5% passing #8 screen). 1200 Airport Drive – South Burlington, VT Passive Soil Venting Design Page 4 of 7 2969 Route 23 South Newfoundland, NJ 07435 / 1-800-949-OBAR / www.obarsystems.com 4. Vapor Barrier A minimum 10 mil vapor retarder or equivalent shall be installed below the stone bed. The vapor retarder under the gravel bed shall not be sealed or have overlapping edges to allow water drainage, it should terminate at foundation walls or adjacent slabs. The purpose of this vapor barrier is to limit air, to the extent practical, from the sub aggregate layer into the conveyance layer. If existing or constructed materials in the subgrade contain earthen materials that contain more than 35% sand, rock fragment fines, clay and silt to restrict permeability from below the sub slab fill layer, then a 10 mil lower vapor retarder is not required. All locations that do not meet this requirement shall have the lower vapor retarder installed in accordance with the aforementioned specifications. A minimum 20 mil vapor barrier or equivalent specifically engineered to serve as a barrier to volatile organic compounds shall be installed above the stone bed. This vapor barrier shall be installed on top of the gravel bed prior to the installation of the slab and shall be overlapped at least 12 inches and have the top overlap tapped to the underside layer using four inch wide tape designated for this application. The tape shall be centered over the top layer edge. The barrier on top of the gravel bed shall be installed so that it abuts the perimeter foundation wall. Any penetrations of the upper layer membrane shall be sealed airtight using the membrane tape in accordance with the manufacturer’s specifications. 5. System Piping The piping installed above and below the slab shall be a combination of 4" and 6" diameter solid PVC (polyvinyl chloride) conforming to ASTM D-1785. The drawing provided (SSD-0) shows the locations of the sub slab piping and vertical riser location. All sub slab piping installed shall be solidly bedded below the slab with a minimum of 1" of stone base under the piping and a minimum of 2" of stone base on top of the piping. For 6" diameter sub slab piping, a minimum of 1" of stone base above and below the pipe is acceptable. Sub slab piping shall have full bearing for each pipe section throughout its length, installed dead level, straight, and in true alignment. For solid sub slab piping, a ½" diameter hole shall be drilled in the bottom of the pipe every 10 feet to allow for condensate drainage. When reducing to a smaller diameter pipe underneath the slab, a ½" diameter hole shall be drilled at the bottom of the larger pipe to allow for condensate drainage. For areas where an elevation change occurs, solid conveyance piping can be installed down vertically to align the lower aggregate layer (See attached System Details sheet). Provide PVC couplings and fittings as required. It is recommended that the crushed stone layer be inspected at every tee location to ensure the minimum depths are met. Soil vent piping routed across unsupported areas prior to installation of thickened slabs or foundation walls shall have 12" bearing on either end for support. Contractor shall determine exact riser position of soil venting pipe riser installed in the crushed stone so that it aligns with appropriate riser location up through the building. The vertical risers shall be 6" schedule 40 PVC (see drawing). Horizontal pipe runs are permitted within the building or the attic as required but all pipes must be pitched back to the slab penetration with at least a one 1200 Airport Drive – South Burlington, VT Passive Soil Venting Design Page 5 of 7 2969 Route 23 South Newfoundland, NJ 07435 / 1-800-949-OBAR / www.obarsystems.com inch pitch for every 8 feet of piping. Soil vent stack piping shall be anchored to building structure at floor intersections and at intermediate locations no greater than every 8 feet of vertical rise and no greater than every 6 feet of horizontal run to prevent movement or rattling of piping network. Supports and anchors shall be clamps and brackets compatible with piping materials. All piping above and below the slab shall be solvent welded according to manufacturer specifications. The vertical riser pipe shall remain accessible on the first floor for the installation of a riser port and a system performance gauge/audible alarm. If the vertical riser becomes inaccessible following construction, then a minimum 8"x8" access panel shall be installed on the first floor to provide access to the vertical riser. See activation section for more information. Above grade vent piping shall be clearly labeled a minimum of every 8 feet with at least one label on each floor. The label shall read "Soil Vent Piping" or equivalent according to state guidelines. 6. Roof Penetrations Roof penetrations should be performed and sealed according to the roofing material specifications. The soil vent pipe should terminate no less than 12 inches above the roofline and no less than 6 feet from the outer edge of the roof and 10 feet from any door, window, HVAC intake, or other direct opening into the building. 7. Concrete Sealing If the ground contact concrete slab abuts against a foundation wall or other surface that produces a cold joint, a peel off expansion joint material shall be installed continuously around the outer edge of the slab. The peel off expansion strip shall be installed so that the top of the strip is flush with the concrete slab, the strip should be installed using adhesive or mechanical fasteners. The peel off strip shall be between 3/8" and 3/4" in width. All peel off expansion joint material shall have the upper peel off section removed and the void space filled with non-cracking polyurethane caulk complying with ASTM C920 class 25 or higher, or equivalent. All visible cracks and control joints in interior concrete slabs that are greater than 1/16" in width shall be sealed utilizing a non-cracking polyurethane caulk complying with ASTM C920 class 25 or higher, or equivalent. Joints, cracks and saw cuts shall be swept or vacuumed clean before application of any sealant. Use caulking manufacturer’s recommendations for installation of caulking for concrete slab floors. Any perimeter or interior joints to be sealed shall have any concrete ridges protruding above the slab height removed prior to sealing. The specified concrete slab sealing shall be done at least 30 days after concrete slab has been installed. Other larger openings through the slab that are open to the sub slab or soil such as plumbing penetrations, sump pits or plumbing block outs shall be sealed with durable material to be airtight. 1200 Airport Drive – South Burlington, VT Passive Soil Venting Design Page 6 of 7 2969 Route 23 South Newfoundland, NJ 07435 / 1-800-949-OBAR / www.obarsystems.com Gaps and utility penetrations through walls or footings that surround the crushed stone layer shall be sealed appropriately to reduce external air from entering the system. Hollow masonry walls in contact with soil shall have a course of hollow block masonry walls that are not vertically lower in elevation than the adjoining exterior grade be made of solid masonry units or be fully grouted per ANSI/AARST CC-1000 guidance. Closure is required for all openings in the wall below this closed course of masonry units, including fully grouted or solid masonry units that surround opening in the wall (i.e. doors, windows and under masonry ledges) and all joints between blocks on both the interior and exterior surfaces. Sump pits open to sub slab soil shall have airtight lids. Openings in or around sump covers shall be sealed with a gasket or use of silicone caulking to allow easy removal for sump pit for maintenance. Sump pits that have a sump pump shall have an access port in the sump pit cover to allow checking of the sump pump without needing to remove the cover. 8. Electric A 240 volt stand-alone electrical power source shall be installed directly below the roof penetration of the soil vent pipe to facilitate future activation of the passive pipe with a depressurization fan. If the ceiling below the roof penetration will be inaccessible following construction, then a 240 volt stand-alone electrical power source shall be installed within 2 feet of the soil vent pipe penetration on the roof to facilitate future activation of the passive pipe with a depressurization fan. All work shall be performed by a licensed electrician. 9. Post Construction Testing When construction is complete and prior to building occupancy, the building should be tested for VOCs in the indoor air in accordance with Vermont DEC Vapor Intrusion Guidance. If VOCs are found in excess of state or local guidance, the system should be activated. Following system activation, indoor air shall be tested in accordance with Vermont DEC testing guidelines. 10. Activation (if required) If activation is required, based on the testing outlined above, the mitigation fans to be installed are GBR 89 or equivalent fans. The fan’s exhaust must be at least ten feet from any opening or intake back into the building that it is not at least two feet above. Active mitigation systems require a visual and audible vacuum monitor. If activation is required, at a minimum, a gauge capable of providing the applied vacuum should be installed (GBR25R gauge or equivalent). ¼" diameter pneumatic tubing shall run from the conveyance piping of the system to the area that the vacuum monitor will be installed while accessible during construction (applies if finishing work will cause conveyance pipe to become inaccessible). There are a range of more advanced monitoring options available. If activation is required, Obar Systems or another mitigation services or monitoring provider should be consulted to evaluate monitoring options. 1200 Airport Drive – South Burlington, VT Passive Soil Venting Design Page 7 of 7 2969 Route 23 South Newfoundland, NJ 07435 / 1-800-949-OBAR / www.obarsystems.com Sub slab monitoring ports will be installed in accessible locations within the system’s radius of influence to confirm sub slab vacuum during commissioning and annual inspections. Suggested monitoring port locations can be provided if activation is required. GBR sub slab monitoring ports will be installed by drilling a 20mm hole and hammering in the port until recessed into the slab.

DRAGO® WRAP VAPOR INTRUSION BARRIER The StegoLife of The Building™ Warranty As the construction industry leader in below-slab barrier materials, Stego offers the first-of-its-kind warranty for its line of vapor barriers and retarders. Warranty information available online at: stegoindustries.com/legal ® 3-in-1 product solution EXPOSURE PATHWAY – VAPOR INTRUSION For brownfields and contaminated sites, the focus has historically been to protect human health by preventing exposure to direct contact of contaminated soil or drinking contaminated water. We now know that inhaling chemical vapors poses a potential risk to the health of residents, workers, and other occupants who are inside of the building envelope. (Source: EPA) A VAPOR INTRUSION BARRIER SOLUTION with Unsurpassed Permeation Coefficients Drago Wrap Vapor Intrusion Barrier is a multi-layered plastic extrusion that combines uniquely designed materials with only high grade, prime, virgin resins. This patent pending barrier tech- nology provides high performance and longevity, allowing for the redevelopment of contaminated sites, creating a healthy built environment. A cost effective 3-in-1 product solution providing unsurpassed protection from chlorinated solvents, hydrocarbons, and moisture vapor. Migration of Soil Vapors to Indoor Air Both diffusion and advection can draw unwanted chemicals into the building envelope. Regardless of the path that soil vapors can take, experts agree that a monolithic layer of protection like the Drago Wrap Vapor Intrusion Barrier System is critical to controlling the transmission of these chemicals into the building.

This exposure pathway, known as vapor intrusion, is the movement of chemical vapors from the soil and groundwater into the building envelope. • In extreme examples, there is a risk of fire or explosion. • Other times, at levels with a detectable odor, there may be acute short-term health issues such as nausea, headache, and respiratory irritation. • More commonly though, long-term exposure to even low-levels of certain chemical vapors may increase the risk of chronic health effects, such as cancer. Drago Wrap Vapor Intrusion Barrier is the next game-changing barrier technology from the creators of Stego® Wrap Vapor Barrier, the most widely-specified below-slab moisture vapor barrier in North America.

Please refer to Tremco Technical Bulletin No. S-09-05 for more information. Substrate Preparation Surfaces must be sound and clean. All release agents, existing waterproofing, dust, loose mortar, paints, other finishes or field applied coating must be removed. This can be accomplished with a thorough wire brushing, grinding, sandblasting, or solvent washing, depending on the contamination. Tremco recommends that surface temperatures be 40 ˚F (5 ˚C) or above at the time the sealant is applied. If sealant must be applied in temperatures below 40 ˚F, please refer to the Tremco Technical Bulletin for Applying Sealants in Cold Conditions (No. S-08-44 rev 1) that can be found on our website at www.tremcosealants.com Priming Vulkem 45SSL typically adheres to common construction substrates without primers. However, Tremco always recommends that a mock-up or field adhesion test be performed on the actual materials being used on the job to verify the need for a primer, proper cleaning and prep requirements. A description of the field adhesion test can be found in appendix X1 of ASTM C1193, Standard Guide for Use of Joint Sealants. Where deemed necessary, use Vulkem® Primer #191 Low-VOC QD on porous substrates and TREMprime® Non-Porous Primer for metals or plastics. Application Vulkem 45SSL is easy to apply with conventional caulking equipment. Ensure that the backer rod is properly friction-fitted and any primers have been applied. Fill the joint completely with a proper width-to-depth ratio, and then tool to ensure intimate contact of sealant with joint substrates. Dry tooling is always preferred, although compatible wetting agents can be used in limited amounts to slick the spatula if needed after an initial pass. For a cleaner finish, mask the sides of the joint with tape prior to filling. Joint Design Vulkem 45SSL may be used in horizontal joints designed in accordance with accepted architectural/engineering practices. Joint width should be 4 times anticipated movement but not less than 1/4" (6 mm). Joint Backing Polyethylene backer rod is recommended as joint backing to control sealant depth and ensure intimate contact of sealant with joint substrate when tooling. Where depth of joint will prevent the use of backer rod, an adhesive backed polyethylene tape (bond breaker tape) should be used to prevent three-sided adhesion. All backing should be dry at the time of sealant application. Vulkem ® 45SSL Semi-Self-Leveling, Single-Component, Polyurethane Sealant www.tremcosealants.com Page 2 of 3 Sealant Dimensions W = Sealant width, D = Sealant depth, Expansion Joints- The minimum width and depth of any sealant application should be 1/4" x 1/4" (6 mm x 6 mm). The depth (D) of sealant may be equal to width (W) of joints that are less than 1/2" wide. For joints ranging from 1/2" to 1" (13 mm to 25 mm) wide, the sealant depth should be approximately one-half of the joint width. The maximum depth (D) of any sealant application should be 1/2" (13 mm). For joints that are wider than 1" (25 mm) contact Tremco Technical Services or your local Tremco Sales Representative. Cure Time At 75 °F (23.9 °C), 50% RH a skin forms within 5 hr. Curing continues at a rate of approximately 1/16" (1.6 mm) per day. The cure time will increase as the temperature and/or humidity decrease. A good rule of thumb is one additional day of cure for every 10 °F decrease in temperature. Cure time can be decreased by adding water when using pails of Vulkem 45SSL. Please refer to the Technical Bulletin No. S-17-01 on Vulkem 45SSL/445SSL Activator that can be found on our website at: www.tremcosealants.com Clean Up Excess sealant and smears adjacent to the joint interface can be carefully removed with xylene or mineral spirits before the sealant cures. Any utensils used for tooling can also be cleaned with xylene or mineral spirits.
