Lakeville, MA 02347 7 RE: RELEASE ABATEMENT MEASURE PLAN SUPPORTING DOCUMENTATION Residential Property—RTN 4-24663 142 Fifth Ave. -West Hyannisport, MA 02672 Dear Mr. Crafton, BENNETT ENVIRONMENTAL ASSOCIATES, INC. (BE A) has prepared the following Release Abatement Measure Plan (RAMP), with Supporting Documentation, as a summary of release discovery and subsequent environmental assessment activities conducted since the release of fuel oil was identified in soils underlying the basement floor on May 16, 2013. Formal Release Notification for the 120-Day Reportable Condition was filed on July 10, 2013 after it was determined that groundwater samples collected from on-site groundwater monitoring wells reported low level petroleum concentrations less than the applicable RCGW-1 Reportable Concentrations and the GW-1, Method 1 - Risk Characterization standards. Following Release Notification, Release Tracking Number (RTN) 4-24663 was assigned to the Site towards the preparation and filing of the following RAM Plan for the implementation of remedial response actions in accordance with the provisions of 310 CMR 40.0440-0448. This RAMP identifies potential exposure risks to human and environmental receptors and sets forth the planned remedial response actions to mitigate such risks towards achieving a permanent solution to support project closure. The RAMP specifies the removal of impacted flooring, excavation and recycling of some 60 yards of impacted soils and the subsequent installation of a structure venting system within the excavated area. This sub-slab venting/SVE system will also provide a preferential pathway for the migration of any organic vapors to the outside of the dwelling and facilitate attenuation of any residually impacted soil. The system infrastructure may also be easily retrofitted as a contingency for the introduction of remedial additives if additional treatment is necessary beyond soil removal. Release discovery was established in connection with an investigation of concrete floor staining and indications of an abandoned underground tank that was conducted by the perspective buyer as part of a real estate transfer.

Laboratory analysis of representative soil samples from both areas reported petroleum hydrocarbon impacts greater than RCS-1 Reportable Concentrations in at least 2 yards of soils as triggering a 120-Day Reportable Condition. Further investigation outside the footprint of the dwelling found an abandoned underground fuel oil storage tank (UST) off.the northeast corner of the dwelling. Both the UST and the AST were subse uentl remo a Zed further environmental assessment was conducte to qualify appropriate Notification and Remedial `. Response actions wherein a threat of groundwater impacts was identified in a mapped Potential Drinking Water Source (PDWSA — GW-1). Subsequent soil testing and analysis was used to identify the horizontal and vertical extent of significant soil impacts as between both the interior and exterior tanks wherein two separate historic releases are indicated. Based on the degree of weathering and interviews with the surviving heirs of the owner, these releases are suspected as being more than 10 years old. Groundwater analytical results show low level groundwater impacts in the vicinity of the former UST (MW-1) but not in the down gradient wells. As such, low level groundwater impact appears to be limited to the art elease as will continue to be monitored throughout the RAM investigation. Additionally, the performance of the RAMP relative to the mitigation of potential exposure risks will further be evaluated by end point sampling of soils for EPHNPH analysis. As dependent upon these results, sub-slab soil vapor sampling may be conducted to evaluate potential vapor entry into the structure if residual volatiles are reported in the VPH analysis. Initial groundwater gauging has established a southwesterly groundwater flow direction with minimal tidal influence. Since monitoring well MW-3 is marginally outside the projected solute pathway from the release area, an additional monitoring well is proposed to be installed further to the west as immediately down gradient and adjacent to the release area as representative of any down gradient impacts or release migration. This well will be sampled within 48 hours of installation and again quarterly in August and October to evaluate seasonal groundwater variations. It is anticipated that soil removal proposed under the RAM can mitigate all significant exposures risks and any potential critical exposure pathways in support of a Class A, Response Action Outcome (RAO) as a permanent solution with a highest degree of confidence. Notwithstanding, no warranty or guarantee of future performance is expressed or implied. It must be recognized that environmental investigations are inherently limited in the sense that conclusions are drawn and recommendations developed from the available information obtained under the context of the regulations and standard of practice at the time of reporting. This work has and will continue to be conducted under direct LSP oversight in a manner consistent with the MCP Response Action Performance Standards (RAPS)pursuant to 310 CMR 40.0191 and the QA/QC policies of BENNETT ENVIRONMENTAL ASSOCIATES, INC. The facts and statements herein are, to the best of our knowledge, a true and accurate representation of the Site activities, remedial response actions and environmental conditions associated with the project and LSP Opinions acknowledged by the certification on the attached BWSC-105 Transmittal Form. JULY 19,2013 IDLEWILD TRUSTBEAI3-10550 PAGE 3 OF 13 RELEASE ABATEMENT MEASURE PLAN/RTN 4-24663 ENVIRONMENTAL CONDITIONS [Refer to Appendix A] The subject property at 142 Fifth Avenue is noted on Barnstable Assessor's Map 245 as Parcel 113 and is located southeast of the intersection of Fifth Ave and Forest Street [Refer to Figure 1] in the Barnstable Village of West Hyannisport. The UTM coordinates for the Site are Northing 4610162m and Easting 390093m. The property contains approximately 0.27 acres of land area and is developed by a one and a half-story residential dwelling and a free-standing garage. The entire property is upland and relatively flat with approximate elevations ranging from 20' NGVD in the northern portion of the property to approximately 18' NGVD along the southern portion. The surrounding area is heavily developed and in similar use as characterized by seasonal and year-round residential properties. Access to the subject property and area of release is unrestricted with high frequency/low intensity of use and children potentially present. The dwelling occupants and visitors to the property are identified as the primary potential human receptors to potential inhalation and dermal contact exposures. Groundwater was encountered at 12-13' below grade_ surface. Regional groundwater contours indicate a southwesterly flow direction toward a small unnamed stream and Centerville Harbor farther west [Refer to Figure 2]. Site-specific groundwater contours were found to be consistent with local flow direction. Based on groundwater flow direction, the small unnamed stream represents the primary potential environmental receptor in consideration of Method 1 — Risk Characterization for potentially receiving impacted groundwater. Based on the MA DEP Priority Resources Map the subject property is not located within the Zone II Protective Radius of a Public Water Supply (PWS), nor is it located within the Zone A protective radius of any surface water reservoir. The Site is shown as a medium-yield potentially productive aquifer as well as a part of the Sole Source Aquifer designated by the EPA for all of Cape Cod east of the canal. As such, the Site is defined as within a Potential Drinking Water Source Area (PDWSA). The Priority Resources Map shows an area of protected open space southwest of the subject property across Fifth Ave. The Priority Resources Map also shows salt and freshwater wetlands to the east, west and south of the Site, as well as NHESP Estimated Habitat of Rare Wildlife in Wetland Areas. Based on the PDWSA designation and proximity to groundwater, the RCGW-1- Reportable Concentrations are applicable per 310 CMR 40.0361, as are the GW-1, GW-2 and GW-3 Method 1 Risk Characterization standards in accordance with 310 CMR 40.0974. Based on residential use and Site conditions including frequency/intensity of use and accessibility of soils, the RCS-1 Reportable Concentrations are applicable per 310 CMR 40.0362, and S-1/S-2/S- 3 (GW-1/GW-2/GW-3), Method 1 — Risk Characterization standards are applicable per 310 CMR 40.0975. These standards were developed in consideration of potential ingestion, inhalation, and environmental exposures, and in review of potential leaching of contaminants to groundwater. In review of potential future use of the property, the strictest S-1 (GW-1) criteria are considered under Method 1 Risk Characterization. JULY 19,2013 IDLEWILD TRUSTBEAI3-10550 PAGE 4 OF 13 RELEASE ABATEMENT MEASURE PLAN/RTN 4-24663 BACKGROUND [Refer to Appendix B] During a home inspection for a pending real estate transaction, the home inspector noted subsurface copper lines, adjacent to an exterior wall, in the northeastern portion of the basement. BEA was.subsequently contracted by the potential buyer's realtor to investigate the utility of the copper lines. As such, BEA personnel traveled to the subject property on May 7, 2013 to investigate the presence of an abandoned UST and to perform hand borings in the area of the copper lines to determine if a release of fuel oil had occurred. Upon arriving at the property, BEA personnel probed the ground adjacent to the northeast corner of the dwelling for signs of an underground tank. A large object, with the approximate dimensions similar to a typical 275- gallon fuel tank was located approximately 2' below grade in this location. A hole was dug and it was confirmed that the object was a steel UST. BEA personnel then went to the basement to perform.hand borings to assess subsurface soils. Upon entering the basement, petroleum staining was observed beneath the existing AST servicing the heating system, representing another possible release of fuel oil to the subsurface. As such, a series of hand borings were advanced to investigate subsurface conditions below the basement slab (Refer to Site Plan). BEA conducted two hand borings (HB-1 and HB-IA) in the area of the AST. HB-1 was angled beneath the tank to the west, perpendicular to the interior basement wall. HB-lA was angled beneath the tank to the northwest, towards the corner of two interior basement walls, where the staining was greatest. Hand boring HB-2 was advanced in the northeastern portion of the basement adjacent to the subsurface copper lines. The hand borings were advanced with a stainless steel bucket auger with soil samples collected in 2' intervals. The samples were then placed in 250-milliliter glass jars with aluminum septa and agitated to develop organic vapors. The samples were subsequently screened by "jar headspace method" with a PID [ThermoEnvironmental 580B OVM (10.8 eV lamp)] as consistent with the Interim Soils Policy (WSC-94-400). PID screening reported elevated organic vapor concentrations < 30 parts per million by volume (ppmv) in H13-1/1-1134A and < 67 ppmv in HB-2. BEA field preserved soil samples HB-IA:2-4' and HB-2:4-6' on ice in a cooler for MA Certified laboratory analysis of risk-based extractable petroleum hydrocarbon (EPH) and target polynuclear aromatic hydrocarbon(PAH) concentrations. Laboratory analysis reported concentrations of fractional C9-C18 Aliphatics and C11-C22 Aromatics greater than the applicable RCS-1 Reportable Concentrations in both soil samples submitted. As such, laboratory analytical had demonstrated significant petroleum hydrocarbon impact in more than two yards of soil, and, in the absence of evidence demonstrating a sudden release, or elevated PID readings (>100 ppmv) in soils, a 120-Day Release Notification requirement was triggered as the basis of remedial response liability.

ENVIRONMENTAL ASSESSMENT/PRELIMINARX RESPONSE [Refer to Appendix B] Soil On June 5, 2013, BEA returned to the site to oversee the removal of both tanks and to perform hand borings below the basement floor to define extent and magnitude of significant fuel oil impact. Upon arrival at the property, Tank Removal Services (TRS) was preparing to pump the contents of the 275-gallon AST in the basement of subject dwelling. The oil was pumped from the tank by Autobody Solvent Recovery Corp. and the tank was then removed from the basement to facilitate soil assessment activities. BEA personnel then used a concrete coring bit JULY 19,2013 IDLEWILD TRUSTBEAI3-10550 PAGE 6 OF 13 RELEASE ABATEMENT MEASURE PLAN/RTN 4-24663 to drill four (4) holes in the basement floor to advance hand borings HB-3 through HB-6 to depth. The hand borings were again advanced with a stainless steel bucket auger with soil samples collected in 2' intervals. The samples were subsequently screened by "jar headspace method" with a PID. Refusal was met in HB-3 at 1' below grade. Concentrations of organic vapors in hand borings HB-4 through HB-6 ranged from Non-Detect (ND) to 58 ppmv, with the highest headspace concentrations in hand boring HB-4. TRS personnel then began to prepare the abandoned UST for removal. The UST was uncovered with a backhoe and was cut open to remove the contents. According to TRS personnel the tank was full of oily water. Autobody Solvent Recovery Corp. then pumped out the tank and transported the contents of both tanks (350 gallons oil/water)to Murphy's Waste Oil Service, Inc. in Woburn, MA (see Manifest provided for reference in Appendix C). The tank was then removed from the ground and inspected for integrity. Barnstable Fire Department personnel (Fire Prevention Officer Don Chase) were at the Site to witness the removal of the tank from the tank grave. Upon inspecting the tank, substantial corrosion was noted with signs of wetness evident on the exterior of the tank. BEA personnel proceeded to collect samples from the tank grave for field screening by jar headspace method. Low organic vapor concentrations (<2.0 ppmv) were reported by field screening the soil samples collected from the bottom of hole of the UST grave. BEA personnel then proceeded to perform hand boring HB-8 in the bottom of the UST.grave to approximately 12' below grade, where groundwater was encountered. Field screening of the soil samples from HB-8 ranged from ND in the 5-7 interval to 64 ppmv in the 9- 10' interval. BEA personnel performed two additional hand borings, HB-9 and HB-10, in the basement of the subject dwelling to further define the eastern and southern extents of soil impact. Field screening of soil samples from HB-9 ranged from ND in the 0-2' interval to 58 ppmv in the 24' interval. In HB-10 all concentrations from field screening were reported as ND. BEA personnel subsequently cleaned up the basement of the dwelling and departed the Site with the preserved samples for extractable petroleum hydrocarbon (EPH + PAHs) and volatile petroleum hydrocarbon(VPH+BTEX) laboratory analyses. Laboratory analytical results, received June 14, 2013, reported fractional C9-C 18 Aliphatics concentrations greater than the strictest S-1/GW-1 Method 1 Risk Characterization Standards in samples collected from hand borings HB-4, HB-7 and HB-8. Cl l-C22 Aromatics concentrations also exceeded the S-1/GW-1 Standards in the sample collected from HB-8: 9-10'. In addition, target analytes were reported above the S-1/GW-1 Standards in HB-4, HB-7, HB-8 and HB-9.

BEA personnel directed Jenkins Well Drilling in the advancement of TB-11, TB-12 and TB-13 towards the installation of monitoring wells MW-1, MW-2 and MW-3, respectively. Test Boring TB-11 was advanced off the northeast corner of the dwelling, in the area of the former UST; TB-12 was advanced south of the dwelling and TB-13 was advanced southwest of the dwelling (Refer to Site Plan). The wells were finished in water-tight road boxes with locking gripper plugs. Top-of-casing elevations were also surveyed to a common vertical datum in review of static water level elevations towards calculating local groundwater flow. Field headspace screening of soil samples collected from the test borings reported low concentrations of organic vapors (<2.0) with the exception of TB-11/1\4W-1 where, in the 17-19' interval a concentration of 18.2 ppmv was reported. A discrete sample at 19' bgs reported a concentration of 38.7 ppmv. Representative soil samples TB-11: 11-13', TB-11@19' and TB- 13:11-13'were prepared and forwarded to a certified laboratory for confirmatory EPH with target •PAH analysis. Laboratory analytical results subsequently reported low-level fractional EPH JULY 19,2013 IDLEWILD TRUST/BEA13-10550 PAGE 8 OF 13 RELEASE ABATEMENT MEASURE PLAN/RTN 4-24663 impacts in the TB-11@19' soil sample as well below the applicable S-1/GW-1 Method 1 -Risk Characterization standards.

As such, remedial response and waste site cleanup activities are prescribed under the RAMP to absolve potential exposure risks and to meet regulatory closure objective without limitation of ctivities or use of the property. Groundwater As presented, the RCGW-1 Reportable Concentrations, as well as the GW-1, GW-2 and GW-3 groundwater categories are applicable in consideration of Method 1 Risk Characterization. These standards were developed to evaluate potential ingestion (GW-1), inhalation (GW-2) and environmental (GW-3) exposures. Groundwater sampling and associated laboratory analysis have reported no_ significant impacts above GW-1 Standards in any of the on-site monitoring wells. However, based on groundwater gauging and site-specific groundwater flow calculations it has been determined that there are no groundwater monitoring wells that are within a definitively down gradient position. As such, one additional monitoring well is prescribed within the RAMP. Indoor Air Indoor ambient air quality within the living space of the residence was screened during the initial Site inspection on May 5, 2013 and has been monitored during subsequent Site visits. The screening has been conducted utilizing a pre-calibrated PID with a 10.6 or 11.8eV lamp. Each indoor air screening event has reported no detectable petroleum odors and background TOV concentrations (<0.1 ppmv) in the dwelling basement. No additional testing has been conducted at this time as the dwelling is currently unoccupied. Indoor air quality will continue to be monitored during subsequent Site inspections for worker safety. During soil removal operations a vapor barrier will be installed between the basement and living area with active ventilation provided. As part of the RAM, all impacted flooring will be removed and replaced inside the dwelling as eliminating interior sources of organic vapors. Pursuant to the Interim Final Vapor Intrusion Guidance (Policy WSC-11-435), as well as anticipated revisions to the MCP, Air-phase Petroleum Hydrocarbon (APH) testing of representative soil vapor beneath the concrete basement slab will supplement the PID screening towards the development of multiple lines of evidence to evaluate potential vapor intrusion and inhalation exposure risks, should residual volatile organic compounds be present within the prescribed setbacks as framed in the provisions of 310 CMR 40.0942(1)(d). Imminent Hazard Evaluation Based on the assessment activities conducted to date, which indicate that all significant fuel oil impacts remain at more than 9' below rg ade or beneath the footprint of dwelling, at which time the dwelling has been largely uninhabited, no Imminent or Substantial Hazards have been identified at the Site. Groundwater monitoring has reported no significant impacts associated with the subject release, and the most recent indoor air quality screening has reported no TOV concentrations within the dwelling above the sensitivity of the instrument (<O.1 ppmv). JULY 19,2013 IDLEWILD TRUST/BEA13-10550 PAGE 11 OF 13 RELEASE ABATEMENT MEASURE PLAN/RTN 4-24663 Monitoring of groundwater, indoor air and soil vapor will continue in review of potential impacts and risk characterization to evaluate potential hazards towards development of a preponderance of physical evidence in qualifying exposure risks and demonstrating No Significant Risk. RELEASE ABATEMENT MEASURE PLAN [Refer to Appendix E] The information from the assessment of current soil and groundwater conditions was used to develop a remedial strategy for the excavation of significantly impacted soils from the identified release area noted on the site plan. This remedial strategy calls for the removal of the concrete floor and impacted subsurface soils to a depth of up to 6' below the basement floor. It is anticipated that as much of 60 cubic yards of impacted soil may be generated. Temporary structural support of the chimney and northeast corner of the subject building will be installed by a licensed contractor with appropriate permitting. Prior to the beginning of work the furnace will be removed. Subsequent to the shoring of the building, the environmental contractor will break up the basement floor and properly dispose of any and all impacted concrete. The contractor will then use an excavator to segregate and stockpile clean overburden material adjacent to the exterior basement walls. Soil removal will then be advanced to depth from the north to the south. Soils will be transported off site under an approved Bill of Lading for direct loading and transportation to Aggregate Industries South Dennis asphalt batching facility. Following the removal of significant soil impact as anticipated in the beginning of August 2013, confirmatory end-point soil samples will be collected for risk-based EPH/VPH analysis, or for TPH analysis as a cost saving measure wherein field-testing indicates petroleum and volatile impacts are clearly absent. After field screening has indicated that risk based closure objectives have been met, a subsurface sub-slab venting/SVE system will be constructed and installed in the excavated area of release. The venting system will be constructed of 4 x 4"perforated PVC pipe laterals, as set in washed stone along the bottom-of-hole area. A 4" solid piece of PVC riser will be plumbed to the lateral components and connected to a wind turbine for the passive venting of residual volatile petroleum compounds. The venting system will also provide the flexibility to deliver remedial additives, as may be necessary to mitigate significant residual soil impacts or for any groundwater treatment. If residual volatile compounds are reported in the end point samples as within 6' horizontally and 10' vertically of the basement floor, a soil vapor probe will be installed and tested for APH. APH analytical results will be compared with the sub-slab screening values set forth in the Interim Final Vapor Intrusion Guidance document (Policy WSC-11-435). This testing may be repeated to establish the prescribed "lines of evidence" rationale to evaluate potential vapor entry into the occupied structure and related inhalation exposures. The monitoring wells will be sampled quarterly in August and October 2013 following soil removal. The quarterly groundwater analysis will be used to evaluate any residual petroleum hydrocarbon impacts to groundwater. The further treatment of soils and/or impacted groundwater will be evaluated from the results of end-point soil sampling and future quarterly groundwater assessment. Specifications of potential remedial equipment, operations and maintenance, or use JULY 19,2013 1DLEWILD TRUSTBEAI3-1055d PAGE 12 OF 13 RELEASE ABATEMENT MEASURE PLAN/RTN 4-24663 of any remedial additives will be represented as a modification of the RAM, if applicable, to be reported in subsequent RAM Status (RAMS) reports. All such work will be compiled on "Inspector's Daily Record of Work Progress"reports and documented in a RAM Status Report or RAM Completion Report to be submitted within 120 days of this filing. CONCLUSIONS The Release Abatement Measure Plan, represented by this filing, proposes the excavation and disposal of up to 30 cubic yards of significantly impacted soils from the release area identified on the Site Plan in Appendix A. Under the RAM Plan, BEA will direct the segregation of clean overburden material surrounding the dwelling to accommodate the excavation and disposal of.contaminated soils. Field PID screening and Dexsil testing will be used by BEA personnel to provide technical assistance and direct excavation operations. A subsurface venting system will be constructed and set in washed stone aggregate prior to final restoration for venting of residual petroleum hydrocarbons, and/or future remedial additive applications if necessary. This work is intended to eliminate the contaminant source and associated exposure risks to identified human and environmental receptors towards achieving a condition of No Significant Risk in support of a permanent solution. This work is scheduled to begin in the beginning of August 2013. A RAM Status Report or RAM Completion Report with Response Action Outcome (RAO) will be submitted within 120 days of this filing. Any subsequent RAM Status Reports will be filed every six months thereafter until a preponderance of physical evidence supports a condition of "No Significant Risk" and RAO objectives are met as supporting an RAM Completion Report. The findings of this investigation, as represented herein, set forth the rationale and technical justification for the LSP Opinions offered, as established by the certifications made on the attached Release Abatement Measure Transmittal Form(BWSC-106).

(BEA) has prepared the following Release Abatement Measure Status I Report (RAMSI) and Supporting Documentation, as a summary of remedial response actions and environmental assessment and exposure risk evaluation conducted since the filing of the Release Abatement Measure Plan (RAMP) on July 24, 2013. Formal Release Notification for the 120-Day Reportable Condition was previously filed on July 10, 2013, to secure Release Tracking Number (RTN) 4-24663, towards the filing of a RAMP for the implementation of remedial response actions to address the discovery of a historic release of fuel oil. The RAMSI documents the completed response actions performed towards contaminant source removal and subsequent environmental monitoring in review of remedial performance and risk characterization. Information from the original RAMP is summarized herein only to orient the reviewer to on-going response actions. Remedial response actions conducted in the reporting period resulted in the removal and remedial waste management of some 60 yards of fuel oil impacted soils from the qualified source area as delineated by preliminary assessment activities. Endpoint soil sampling and analysis at the extent of excavation reported effective removal of impacted soils in all areas with°the exception of a sidewall area (SW-NW: 6-1 l') in Zone B of the excavation where additional soil removal was not possible without endangering the structural integrity of the building although extensive shoring was provided. Wherein all fractional EPHIVPH compounds and target analyte concentrations where less than the most stringent S-1/GW-1, Method I — Risk Characterization standards with the exception of this single sidewall area, under the provisions of 310 CMR 40.0926, and Exposure Point Concentration (EPC) was developed in review of exposure risks and regulatory closure objectives. Under such considerations, 2-methynaphthatlene remained above the S-11GW-1 leaching based standard of 0.7 mg/kg and further consideration of alternative leaching based standards under Method 2 and Method 3 are being considered under the provisions of 310 CMR 40.0983 to 40.0985. A preponderance of physical evidence has been developed under Method 2 to evaluate the presence of any 2-methynaphthalene associated with EMERGENCY SPILL RESPONSE 6 WASTE SITE CLEANUP 6 SITE ASSESSMENT & PERMITTING & SEPTIC DESIGN&INSPECTION WATER SUPPLY DEVELOPMENT,OPERATION&MAINTENANCE 6 WASTEWATER TREATMENT,OPERATION&MAINTENANCE NOVEMBER 19,2013 IDLEWILD TRUSTBEAI3-10550 PAGE 2 OF 23 RELEASE ABATEMENT MEASURE STATUS I,RTN 4-24663 the historic release of fuel oil in down gradient monitoring wells. No such groundwater impacts have been reported in the three rounds of groundwater sampling conducted and additional quarterly groundwater sampling in the first quarter of 2014 will complete this Method 2 evaluation. Additionally, the use of the MA DEP Method 3 ShortForms considering both the "worst case " discrete exposure and EPC, both produced Hazard Index (HI) and Excess Lifetime Cancer Risk. indicating No Significantly Risk as associated with residual soil impacts at the subject Site following soil removal. Groundwater sampling and analysis through the reporting period showed no impacts in down gradient monitoring wells. However, in MW-1 closest to the release area and adjacent to the area of excavation, the most recent quarterly VPH/EPH analytical results reported concentrations of EPH C11-C22 aromatics compounds in monitoring well MW-1 slightly greater than the applicable and strictest GW-1, Method 1 Risk Characterization standards. At the time of such sampling, the well had very little water as attributed to drought conditions and the sample was very turbid. As such, an additional quarterly groundwater event is proposed herein to qualify this residual impact over time wherein both filtered and unfiltered samples will be run for EPH analysis if with increased available water,turbidity persists. Indoor air quality screening was continued through the reporting period as supplemented by sub-slab soil vapor testing following the completion of soil removal activities. Prior to construction activities, a vapor barrier was constructed to isolate the unfinished basement area from the living space and active ventilation used during the course of soil removal activities. PID screening reported organic vapors as Non-Detect (ND < 0.2 ppmv) during work activities with engineering controls and following the completion of work and replacement of the concrete floor. A soil vapor probe was installed through the newly poured basement floor within the area of excavation and APH samples collected using a summa canister in accordance with current standard of practice and vapor intrusion policy WSC-11-435. Analytical results for both sampling rounds report soil vapor concentrations for target volatile analytes as less than the published threshold values. These lines of evidence further support a condition of No Significant Risk associated with vapor entry and inhalation exposure risks. Even though the area is serviced by town water and there are no known wells within 500' of the Site, by definition as a potential drinking water source area (PDWSA), residual groundwater impacts reported in monitoring well MW-1 could represent a potential ingestion exposure risk, and as such additional groundwater sampling is appropriate and necessary in review of potential exposure risks to human receptors. The additional round of groundwater sampling will also support the Method 2 evaluation of alternative leaching based standards for 2- rhethynphthalene. It is anticipated that with this additional round of sampling, potential exposures risks can be qualified to document No Significant Risk to meet regulatory closure as a permanent solution. Such determinations continue to be evaluated with the development of additional data and realization of Site conditions. Future environmental monitoring activities will dictate the need for any additional remedial measures to be represented in future RAM Status reports. The NOVEMBER 19,2013 IDLEWILD TRUST/BEA13-10550 PAGE 3 OF 23 RELEASE ABATEMENT MEASURE STATUS I,RTN 4-24663 subsequent groundwater monitoring activities proposed herein are intended to mitigate any Critical Exposure Pathways and Significant Risk to identified human and environmental receptors towards a Permanent Solution in support of a Class A, Response Action Outcome (RAO). The information herein serves as the technical rationale and scientific justification for the environmental assessment and response actions previously conducted and those further activities proposed within. This work has and will continue under direct LSP oversight in a manner consistent with the MCP Response Action Performance Standards (RAPS)pursuant to 310 CMR 40.0191 and the QA/QC policies of BENNETT ENVIRONMENTAL ASSOCIATES, INC. The facts and statements herein are, to the best of our knowledge, a true and accurate representation of the Site activities, remedial response actions and environmental conditions associated with the project and LSP Opinions acknowledged by the certification on the attached BWSC-106 Transmittal Form. ENVIRONMENTAL CONDITIONS [Refer to Appendix A] The subject property at 142 Fifth Avenue is noted on Barnstable Assessor's Map 245 as Parcel 113 and is located southeast of the intersection of Fifth Ave and Forest Street [Refer to Figure 1] in the Barnstable Village of West Hyannisport. The UTM coordinates for the Site are Northing 4610162m and Easting 390093m. The property contains approximately 0.27 acres of land area and is developed by a one and a half-story residential dwelling and a free-standing garage. The entire property is upland and relatively flat with approximate elevations ranging from 20' NGVD in the northern portion of the property to approximately 18' NGVD along the southern portion. The surrounding area is heavily developed and in similar use as characterized by seasonal and year-round residential properties. Access to the subject property and area of release is unrestricted with high frequency/low intensity of use and children potentially present. The dwelling occupants and visitors to the property are identified as the primary potential human receptors to potential inhalation and dermal contact exposures. Groundwater was encountered at 12-13' below grade surface. Regional groundwater contours indicate a southwesterly flow direction toward a small unnamed stream and Centerville Harbor farther west [Refer to Figure 2]. Site-specific groundwater contours were found to be consistent with local flow direction. Based on groundwater flow direction, the small unnamed stream represents the primary potential environmental receptor in consideration of Method 1 — Risk Characterization for potentially receiving impacted groundwater. Based on the MA DEP Priority Resources Map the subject property is not located within the Zone lI Protective Radius of a Public Water Supply (PWS), nor is it located within the Zone A protective radius of any surface water reservoir. The Site is shown as a medium-yield potentially productive aquifer as well as a part of the Sole Source Aquifer designated by the EPA for all of Cape Cod east of the canal. As such, the Site is defined as within a Potential Drinking NOVEMBER 19,2013 IDLEWILD TRUSTBEAI3-10550 PAGE 4 OF 23 RELEASE ABATEMENT MEASURE STATUS I,RTN 4-24663 Water Source Area (PDWSA).

Based on the PDWSA designation and proximity to groundwater, the RCGW-1 Reportable Concentrations are applicable per 310 CMR 40.0361, as are the GW-1, GW-2 and GW-3 Method 1 Risk Characterization standards in accordance with 310 CMR 40.0974. Based on residential use and Site conditions including frequency/intensity of use and accessibility of soils, the RCS-1 Reportable Concentrations are applicable per 310 CMR 40.0362, and S-1/S-2/S- 3 (GW-1/GW-2/GW-3), Method 1 — Risk Characterization standards are applicable per 310 CMR 40.0975. These standards were developed in consideration of potential ingestion, inhalation, and environmental exposures, and in review of potential leaching of contaminants to groundwater. 'In review of potential future use of the property, the strictest S-1 (GW-1) criteria are considered under Method 1 Risk Characterization. BACKGROUND [Refer to Appendix B] During a home inspection for a pending real estate transaction, the home inspector noted subsurface copper lines, adjacent to an exterior wall, in the northeastern portion of the basement. BEA was subsequently contracted by the potential buyer's realtor to investigate the utility of the copper lines. As such, BEA personnel traveled to the subject property on May 7, 2013 to investigate the presence of an abandoned UST and to perform hand borings in the area of the copper lines to determine if a release of fuel oil had occurred. Upon arriving at the property, BEA personnel probed the ground adjacent to the northeast corner of the dwelling for signs of an underground tank. A large object, with the approximate dimensions similar to a typical 275- gallon fuel tank was located approximately 2' below grade in this location. A hole was dug and it was confirmed that the object was a steel UST. BEA personnel then went to the basement to perform hand borings to assess subsurface soils. Upon entering the basement,petroleum staining was observed beneath the existing AST servicing the heating system, representing another possible release of fuel oil to the subsurface. As such, a series of hand borings were advanced to investigate subsurface conditions below the basement slab (Refer to Site Plan). BEA conducted two hand borings (HB-1 and HB-lA) in the area of the AST, and an additional boring in in the area of the copper lines (HB-2). HB-1 was angled beneath the tank to the west, perpendicular to the interior basement wall. HB-lA was angled beneath the tank to the northwest, towards the corner of two interior basement walls, where the staining was greatest. Hand boring HB-2 was advanced in the northeastern portion of the basement adjacent to the subsurface copper lines to investigate soil conditions in this location. The hand borings were advanced with a stainless steel bucket auger with soil samples collected in 2' intervals. The samples were then placed in 250-milliliter glass jars with aluminum septa and agitated to develop organic vapors. The samples were subsequently screened by "jar headspace method" with a PID [ThermoEnvironmental 580B OVM (10.8 eV lamp)] as consistent with the Interim Soils Policy (WSC-94-400). PID screening reported elevated organic vapor concentrations < 30 parts per NOVEMBER 19,2013 IDLEWILD TRUST/BEA13-10550 PAGE 5 OF 23 RELEASE ABATEMENT MEASURE STATUS I,RTN 4-24663 million by volume (ppmv) in HB-1/HB-lA and < 67 ppmv in HB-2. BEA field preserved soil samples HB-lA:2-4' and HB-2:4-6' on ice in a cooler for MA Certified laboratory analysis of risk-based extractable petroleum hydrocarbon (EPH) and target polynuclear aromatic hydrocarbon(PAH) concentrations. Laboratory analysis reported concentrations of fractional C9-C 18 Aliphatics and C 11-C22 Aromatics greater than the applicable RCS-1 Reportable Concentrations in both soil samples submitted. As such, laboratory analytical had demonstrated significant petroleum hydrocarbon impact in more than two yards of soil, and, in the absence of evidence demonstrating a sudden release, or elevated PID readings (>100 ppmv) in soils, a 120-Day Release Notification requirement was triggered as the basis of remedial response liability.

ENVIRONMENTAL ASSESSMENT/PRELIMINARY RESPONSE Soil On June 5, 2013, BEA returned to the site to oversee the removal of both tanks and to perform hand borings below the basement floor to define extent and magnitude of significant fuel oil impact. Upon arrival at the property, Tank Removal Services (TRS) was preparing to pump the contents of the 275-gallon AST in the basement of subject dwelling. The oil was pumped from the tank by Autobody Solvent Recovery Corp. and the tank was then removed from the basement to facilitate soil assessment activities. BEA personnel then used a concrete coring bit to drill four (4) holes in the basement floor to advance hand borings HB-3 through HB-6 to depth. The hand borings were again advanced with a stainless steel bucket auger with soil samples collected in 2' intervals. The samples were subsequently screened by "jar headspace method" with a PID. Refusal was met in HB-3 at 1' below grade. Concentrations of organic vapors in hand borings HB-4 through HB-6 ranged from Non-Detect (ND) to 58 ppmv, with the highest headspace concentrations in hand boring HB-4. i TRS personnel then began to prepare the abandoned UST for removal. The UST was uncovered with a backhoe and was cut open to remove the contents. According to TRS personnel the abandoned UST was full of oily water (200 gallons +/-). Autobody Solvent Recovery Corp. then pumped out the UST, and existing basement AST oil tank in preparation for soil removal, and transported the contents of both tanks (350 gallons oil/water) to Murphy's Waste Oil Service, Inc. in Woburn, MA (see Manifest provided for reference in Appendix Q. The tank was then removed from the ground and inspected for integrity. Barnstable Fire Department personnel (Fire Prevention Officer Don Chase) was at the Site to witness the removal of the tank from the tank grave. Upon inspecting the tank, substantial corrosion was noted with signs of wetness evident on the exterior of the tank. BEA personnel proceeded to collect samples from the tank grave for field screening by jar headspace method. Low organic vapor concentrations (<2.0 ppmv) were reported by field screening the soil samples collected from the bottom of hole of the. UST grave. BEA personnel then proceeded to perform hand boring HB-8 in the bottom of the UST grave to approximately 12' below grade, where groundwater was encountered. Field screening of the soil samples from HB-8 ranged from ND in the 5-7 interval to 64 ppmv in the 9-10' intervals. BEA personnel performed two additional hand borings, HB-9 and HB-10, in the basement of the subject dwelling to further define the eastern and southern extents of soil impact. Field screening of soil samples from HB-9.ranged from ND in the 0-2' interval to 58 ppmv in the 24 interval. In HB-10 all concentrations from field screening were reported as ND. BEA personnel subsequently cleaned up the basement of the dwelling and departed the Site with the NOVEMBER 19,2013 IDLEWILD TRUST/BEA13-10550 PAGE 7 OF 23 RELEASE ABATEMENT MEASURE STATUS I,RTN 4-24663 preserved samples for extractable petroleum hydrocarbon (EPH + PAHs) and volatile petroleum hydrocarbon(VPH+BTEX) laboratory analyses.

As such, BEA personnel returned to the site on July 31, 2013 to install monitoring well MW-4 in a definitive down gradient location. BEA returned to the site on August 2, 2013 to survey in the well to a common datum with the existing wells, as well as to develop and sample the well. However, the well was very silty and very slow to recharge, as such, sampling the well was rescheduled until the following week to coincide with oversight of shoring installation. As such, BEA personnel returned to the Site on August 7, 2013 to sample monitoring well MW-4 and to oversee the installation of atlas piers for structure support. Groundwater samples were collected from monitoring well MW-4 and were package for delivery to a MA certified laboratory for EPH/PAHs and VPH/BTEX analysis. Laboratory analytical results were reported on August 15, 2013. The results reported trace concentrations of the target analyte Naphthalene (0.461 ug/1),just above the reporting limits of the analysis. No other concentrations of fractional EPH/VPH or target analytes were reported. RELEASE ABATEMENT MEASURE [Refer to Appendix B] Soil Removal Operations Following the submittal of the RAMP on July 24, 2013 BEA coordinated remedial response actions with the selected contractor, Frank Corp. Environmental Services (FCES) of New Bedford, MA. On August 7, 2013, BEA personnel were at the site to oversee the removal of impacted soils starting at the exterior of the dwelling along Forest Street. Upon arrival at the Site,the clean overburden material in the area of proposed excavation was observed as stockpiled in the driveway northeast of the house. The vapor barrier had been constructed and basement area actively ventilated with dwelling vacant. Workers were installing the final helical pier to support the buildings foundation. After the completion of the final pier, FCES personnel began breaking up the basement floor inside the dwelling to facilitate soil removal beneath the dwelling. Frank Corp. personnel then began to excavate impacted soils from outside the house and loading them into a waiting dump truck for off-site recycling. A single truckload of impacted soils was transported to Aggregate Industries asphalt batching plant in South Dennis for recycling. Frank Corp. personnel then began to shovel impacted soils from inside the basement to the open excavation outside the dwelling in anticipation of removing additional impacted soils the following day. The excavation was then secured with fencing until work began the following day. BEA returned the next day to inspect work progress and qualify performance. Upon arrival at the site, Frank Corp. personnel were removing impacted soils from the northern portion of the excavation, outside the dwelling (Zone A). After removing soils to 14', BEA collected end-point soil samples from the extent of excavation for field testing. PID screening reported elevated readings of organic vapors along the north sidewall (54 ppmv) and west sidewall (7 ppmv). As such the operator was instructed to scrape down the western sidewall and to extend I NOVEMBER 19,2013 IDLEWILD TRUST/BEA13-10550 PAGE 11 OF 23 RELEASE ABATEMENT MEASURE STATUS I,RTN 4-24663 the northern sidewall one-buckets width. After the removal of some ornamental plants, additional overburden material was stockpiled in the driveway to facilitate the removal of impacted soils along the north and west sidewalls of the excavation. Subsequent to the removal of additional soils, samples were recollected from the northern and western sidewalls as well as from the bottom of hole location, for field screening by PID. PID readings from the extended sidewalls reported low organic vapor concentrations (<5.Oppmv), apparently defining the lateral extent of impact in this portion of Zone A. The bottom of hole sample reported a 62 ppmv PID reading, and a Dexsil PetroFlag reading of 482 ppm TPH, indicating that the excavation was approaching the limits of significant impact. BEA personnel then accessed the inside of the basement and collected a soil sample from the northwest portion of the interior of the dwelling (Zone B) for field screening. PID screening from soil sample Zone B SW-NW: 10-12' reported a concentration of 62 ppmv and a PetroFlag result beyond the limits of the test (2000+ppm), indicating additional soil removal was required in this area. Four representative sidewall and bottom of hole samples from Zone A (Zone A SW- N: 5-14', SW-E: 5-14', SW-W: 5-14' and BOH@15') were submitted to a MA Certified Laboratory for EPH/PAH and VPH/BTEX analysis. A clean overburden stockpile sample was also submitted for TPH analysis. Three truckloads of impacted soils were transported to the recycling facility on this day. BEA returned to the subject property on August 12, 2013 to inspect work progress and direct on-going excavation operations. Upon arrival at the site, FCES personnel were inside the basement removing soils from the identified area of impact in Zone B. FCES personnel were instructed to remove soils in the southern portion of Zone B to 4' below the basement slab (10' below grade), consistent with previous soil assessment. Soil samples were then collected from the 6-10' interval from the southern portion of Zone B and screened in the flied using a PID. Field screening of soils from Zone B (south) reported PID readings between 1.2 in the southeast sidewall sample (SW-SE: 6-10') and 47 ppmv in the sample collected beneath the knee wall (SW-center: 6-10'). A Dexsil PetroFlag test was then performed on the SW-center: 6-10' sample with a result of 2000+ ppm TPH, which indicated additional soils needed to be removed from this portion of Zone B. Frank Corp personnel were instructed to continue removing soils from this portion of the excavation to 5' below the basement slab (11' below grade). The sidewall and bottom of hole samples were then recollected and screened with a PID. PID readings reported organic vapors ranging from 1.2 ppmv in the SW-S: 6-11 sample 34 ppmv in the SW-center: 6- 11' sample, beneath the knee wall. At this point, Frank Corp. personnel had advanced the southern portion of Zone B as deep as possible without the use of a shoring box. Additionally, the need to remove material from beneath the concrete block knee wall required the review of structural engineer retained for shoring specifications and load bearing considerations. As such, the excavation was secured for the removal of additional soil the following day. Five samples from Zone B (Zone B SW-SE: 6-1 P, SW-S: 6-1 F, B0H-SE@11', SW-SW: 6-11' and BOH-SW@11') representing the sidewall and bottom of hole areas (south of the concrete block knee wall) were submitted to a MA certified laboratory for EPH and VPH analysis to qualify the extent of impacted soils in the southern portion of Zone B. Based on the NOVEMBER 19,2013 IDLEWILD TRUST/BEA13-10550 PAGE 12 OF 23 RELEASE ABATEMENT MEASURE STATUS I,RTN 4-24663 field screening results, two of the samples (Zone B SW-SW: 6-11' and Zone B BOH-SW@l F) were submitted for a rush turnaround to determine if additional soils needed to be removed in these areas, while the remaining samples were submitted for a standard 5-day turnaround. Two additional loads of impacted soil were taken to the recycling facility on this day. BEA personnel returned to the Site on August 13, 2013, to oversee the removal of additional soils from the northern portion of Zone B. Upon arrival, Frank Corp. personnel were removing impacted soils from Zone B by shoveling the material into the open excavation (Zone A) and then using the excavator to scoop the impacted material and load it into a waiting dump truck. Samples were collected from the extent of excavation and screened in the field with a PID. Results of field screening reported concentrations of organic vapors ranging from 55 ppmv in the northwest sidewall (SW-NW: 6-1 P) to 12.3 ppmv in the bottom of hole sample (BOH@ll'). FCES personnel were then instructed to remove additional material from the northeastern portion of Zone B from the sidewall and bottom of hole areas. The samples were then recollected with low PID readings observed (<10 ppmv). At this point the limits of the excavation were being reached without endangering the structural integrity of the chimney. Therefore, no additional material could be removed from the northwestern portion of the excavation. Based on field screening results, additional soils beneath the concrete block knee wall were impacted and required removal. As such, BEA personnel consulted with Chris Blake (Frank Corp.), who indicated that soils could be removed from beneath the knee wall safely up until a point approaching the base of the existing chimney. Frank Corp. personnel were then instructed to remove the impacted soils from beneath the knee wall to the eastern foundation wall. Representative endpoint soil samples from Zone B, north of the concrete block knee wall, were then submitted to a MA certified laboratory for EPH/PAH and VPH/BTEX analysis. The sample from the northwest portion of the excavation adjacent to the chimney was submitted for a rush turnaround to determine if additional soil removal was required, or if Method 3 Risk Characterization could be used to mitigate significant risk. A single truckload of impacted soils was transported off site on this day to Aggregate Industries South Dennis, MA asphalt batching facility, for a total of seven loads over seven days of work. BEA then authorized the contractor to stabilize the excavation with washed stone as would be used for the proposed infiltration gallery. Given that the limits of safe contaminated soil removal had been reached with field testing indicating good performance, the contractor was further authorized to complete the infiltration system and complete backfill towards dwelling stabilization and re-use of the subject property. The infiltration system was specifically constructed to be retrofitted for additional soil treatment, or groundwater treatment if necessary as would be driven by review and consideration of endpoint laboratory analysis. Laboratory analytical results from the representative sidewall and bottom of hole endpoint soil samples were received on August 19 and 20, 2013. Laboratory analysis reported all EPH/PAH and VPH/BTEX concentrations for Zone A as significantly less than the strictest applicable S-1 (GW-1/GW-2/GW-3) Method 1 Risk Characterization thresholds with modest f NOVEMBER 19,2013 IDLEWILD TRUSTBEAI3-10550 PAGE 13 OF 23 RELEASE ABATEMENT MEASURE STATUS I,RTN 4-24663 residual fractional EPH impact reported along the north, east and west sidewall samples. The Zone A Bottom of hole sample also reported modest fractional EPH,VPH and target analytes. i Zone B confirmatory soil samples reported all carbon range and target PAH concentrations as less than the strictest S-1 (GW-1/GW-1/GW-3) Method 1 criteria with the exception of the northwest sidewall adjacent to the chimney footing. Significant concentrations of C9-C18 Aliphatics, 2-methylnaphthalene, Acenaphthene, C9-C10 Aromatics and Naphthalene were reported above the strictest S-1 (GW-1/GW-1/GW-3) Method 1 Standards. The sum of analytical results for soil samples collected from the extent of contaminated soil removal is presented in the following Tables 5 and 6. The Tables present end-point sample data based on soil category in order to develop applicable Exposure Point Concentrations to further qualify risk characterization under Method 1, Method 2 and Method 3 Risk Characterization.

BEA returned to the Site on September 5, 2013 to'perform sub-slab vapor monitoring and groundwater monitoring in review of the remedial response performance. Static water level measurements demonstrated a southwest flow direction as consistent with historic monitoring. BEA employed low-flow sampling to monitor field parameters (temperature, pH, dissolved oxygen, conductivity) with a calibrated YSI instrument to qualify potential fuel oil impact to shallow groundwater. Upon parameter stabilization, each well was sampled for EPH/PAHs and VPH/BTEX analysis. Due to the slow groundwater recharge at the Site, BEA personnel had to return to the site the following day to finish collecting the samples from monitoring well MW-1. BEA received the results of groundwater monitoring on September 16, 2013. The results reported all concentrations of fractional EPH and target PAHs as well as fractional VPH and f NOVEMBER 19,2013 IDLEWTLD TRUST/BEA13-10550 PAGE 15 OF 23 RELEASE ABATEMENT MEASURE STATUS I,RTN 4-24663 target BTEX analytes as below the method detection limits of the analyses (non-detect), wherein the detection limits were less than or equal to the applicable and strictest GW-1, Method 1 Risk Characterization standards. BEA returned to the site again on October 17, 2013 to perform groundwater and sub-slab vapor monitoring at the Site. Low-flow groundwater sampling was employed to collect groundwater samples for EPH/PAHs and VPH/BTEX analysis. Results of the October groundwater sampling event were reported on October 25, 2013. The results reported low concentrations of aromatic EPH (C 11-C22) impact in monitoring well MW-1 marginally above the applicable and strictest GW-1, Method 1 Risk Characterization standard. Concentrations of C19-C36 Aliphatics and C9-C18 Aliphatics were also reported in MW-1 below GW-1 Standards. The balance of EPH, VPH and target analyte concentrations in MW-1 were reported as non- detect, wherein the detection limits were less than or equal to the strictest GW-1, Method 1 Risk Characterization standards. The remainder of monitoring wells reported all EPHNPH and target analyte concentrations as non-detect (ND). The sum of groundwater analytical results is presented in Table 7.

Upon entry to the basement, BEA reported no detectable petroleum odor with PID readings as ND (<0.1 ppmv). The sub-slab infiltration system riser was to be constructed of solid 4", schedule 40 PVC piping and run above grade with a tee-y and capped for possible remedial additive use if subsequent groundwater sampling results reported concentrations of residual impact. The infiltration system also serves as a way to measure any residual vapors in soil remaining below the slab. In consideration of such testing, no PVC glue was to be used, and the riser components were to be friction-fit, in order to absolve potential interference from the PVC solvent. BEA related such instructions to the environmental contractor. BEA returned to the Site on September 5, 2013, to perform groundwater monitoring, as described above, and to conduct APH testing of soil vapor. Upon arrival at the Site a brass Vapor-PinTM was installed through the concrete basement floor. Given that the area of contaminated soil removal had been capped with plastic sheeting and subsequently backfilled with flowable fill as would restrict the mobility of residual petroleum volatiles, the Vapor-Pin TM was installed marginally beyond the Zone B area of soil removal in order to evaluate the potential for soil vapor intrusion (Refer to Site Plan, Appendix D). Prior to such sampling, BEA performed PID screening throughout the basement of the dwelling and at the sub-slab infiltration system riser wherein all TOV concentrations were reported as consistent with background (0.0- 0.2 ppmv) and no persistent petroleum odor was noted in the unfinished basement area. BEA subsequently purged the vapor point with a PID for ten minutes prior to sample collection. During the purging of the vapor point, no concentrations of organic vapors were reported on the PID. BEA personnel then collected an APH sample from SVP-1 by way of a summa canister under vacuum. Laboratory analytical results were reported on September 13, 2013. The soil vapor testing results associated with the APH testing of SVP-1 reported all carbon range and target analyte concentrations as significantly less than the applicable Residential Sub-Slab Soil Vapor Screening Values. BEA returned to the Site on October 17, 2013, to perform another round of groundwater monitoring, and to again conduct APH testing of soil vapor. BEA performed PID screening throughout the basement of the dwelling and at the sub-slab infiltration system riser wherein all TOV concentrations were again reported as consistent with background (0.0-0.2 ppmv) and no petroleum odor was noted in the basement area. BEA subsequently purged the vapor point prior to sample collection. BEA personnel then collected an APH sample from SVP-1 by way of a summa canister over a ten minute exposure. Laboratory analytical results were reported on October 25, 2013. Again, the soil vapor testing results associated with the APH testing of SVP-1 reported all carbon range and target analyte concentrations as significantly less than the applicable Residential Sub-Slab Soil Vapor Screening Values.

These standards were developed to evaluate potential ingestion (S-1), inhalation (S-2) and environmental (S-3) exposures, and in consideration of potential leaching of contaminants to groundwater (GW-1/GW-2/GW-3). For the purposes of risk characterization, the strictest S-1/S- 2/S-3 (GW-1), Method 1 Risk Characterization standards are initially considered in review of exposures related to foreseeable future uses and activities at the Site as the most conservative approach. As previously noted, all fractional EPH/VPH compounds and target analyte concentrations in endpoint soils where less than the most stringent S-1/GW-1, Method 1 — Risk Characterization standards with the exception of this single sidewall area. Under the provisions of 310 CMR 40.0926, and Exposure Point Concentration (EPC) was developed in review of exposure risks and regulatory closure objectives. Based on the computed EPC, the averaged 2- methylnaphthalene concentration remained above than the strictest S-1 (GW-1) threshold [2.7 ppm > 0.7 ppm (S-1/GW-1)]. Such that 2-methynaphthatlene GW-1 standards are strictly NOVEMBER 19,2013 IDLEWILD TRUSTBEAI3-10550 PAGE 18 OF 23 RELEASE ABATEMENT MEASURE STATUS I,RTN 4-24663 leaching based [Refer to Table 9], further consideration of alternative standards under Method 2 and Method 3 are were considered under the provisions of 310 CMR 40.0983 to 40.0985. Under Method 2, a preponderance of physical evidence has been developed to evaluate the presence of any 2-methynaphthalene associated with the historic release of fuel oil in down gradient monitoring wells. No such groundwater impacts have been reported in the three rounds of groundwater sampling conducted as supports a finding of No Significant Risk associated with residual concentrations of 2-methynaphthalene. Additional quarterly groundwater sampling in the first quarter of 2014 will complete this Method 2 evaluation and qualify such preliminary findings. _..... ..... Table.9.: .

Therefore, laboratory analysis under Method 2 and Method 3 has demonstrated effective soil remediation and a condition of No Significant Risk with respect to soils at the Site as will be further substantiated by additional groundwater sampling and analysis. Groundwater As presented, the subject property is mapped within a PDWSA as considers potential water supply development and ingestion exposure risks. Based on the PDWSA designation for NOVEMBER 19,2013 IDLEWILD TRUST/BEA13-10550 PAGE 20 OF 23 RELEASE ABATEMENT MEASURE STATUS I,RTN 4-24663 the subject property and surrounding area, as well as the depth to groundwater, the GW-1, GW-2 and GW-3 groundwater categories are applicable to Method 1 Risk Characterization. These standards were developed to evaluate potential ingestion (GW-1), inhalation (GW-2) and environmental (GW-3) exposures. For the purposes of risk characterization, the most restrictive GW-1/GW-2/GW-3, Method 1 - Risk Characterization standards are considered. In the initial two rounds of groundwater testing, no significant impact to groundwater relative to the Method 1 standards was noted although C 11 to C22 aromatic concentration were reported in the up gradient MW-1 monitoring well closest to the former abandoned underground tank. Following the removal of impacted soils, the most recent groundwater testing has reported concentrations of fractional EPH in monitoring well MW-1 again with the C11-C22 fraction reported as above the most stringent GW-1, Method 1 Risk Characterization standards. All other EPH and target PAH concentrations in MW-1 and all other existing wells were reported as significantly less than the strictest GW-1 criteria or as non-detect. Increased aromatic concentrations in MW-1 are suspected as related to its proximity to soil removal operations and low water levels with high turbidity in the samples. Further seasonal evaluation of this well as a discreet exposure will be considered. Monitoring wells MW-3 and MW-4 have been established as downgradient from the release area and within the spatial and temporal.solute transport pathways. Both monitoring wells MW-3 and MW-4 have reported concentrations of EPHNPH and all target analytes as non-detect, with the exception of trace concentrations of Naphthalene in MW-4 during the initial sampling event in August. In all groundwater analysis conducted to date, concentrations of EPH/VPH compounds and target analytes have been less than the GW-2 and GW-3, Method 1 Risk Characterization standards. This data supports a finding of No Significant Risk of organic vapors being released from groundwater and entering the occupied dwelling creating as an inhalation exposure (GW-2) nor significant impacts to down gradient environmental resources (GW-3). The evaluation of practical exposure risks considers that water supply development at the Site and surrounding area is likely precluded by dense residential development on lots ranging from 1/4 to 1/2 acre in size, and may be further precluded by possible brackish conditions based on the-proximity to Nantucket Sound. Furthermore, the Site and surrounding residential properties are served by the Barnstable Water Company distribution system (PWS) as practically absolving exposure risks associated with the ingestion of contaminated groundwater. Based on the PWS service to the subject property and laboratory analytical that has reported all petroleum hydrocarbon concentrations in groundwater as significantly less than the no Imminent or Substantial Hazard conditions associated with groundwater are apparent at the present time as to be further qualified by future testing to document a condition of No Significant Risk for all foreseeable future use of the property, including as a source of potable water. Indoor Air The VPH analysis conducted on end-point soil samples reported some residual volatile r NOVEMBER 19,2013 IDLEWILD TRUST/BEA13-10550 PAGE 21 OF 23 RELEASE ABATEMENT MEASURE STATUS I,RTN 4-24663 carbon range and target VOC concentrations as marginally above the strictest S-1 (GW-1/GW- 2/GW-3), Method 1 Risk Characterization standards. The majority of such concentrations in end-point samples were reported as ND wherein the reporting limits were significantly less than the most restrictive S-1 (GW-l/GW-2/GW-3), Method 1 Risk Characterization Standards. However, in accordance with the provisions of 310 CMR 40.0942(1) (d), if one or more VOCs is present in vadose zone soil adjacent to an occupied structure (i.e. within 6' horizontally from the wall of the structure or 10' vertically from the basement floor) then the soil has the potential to result in significant indoor air concentrations of OHM and Method 1 alone cannot be used to characterize risk at the Site. Indoor ambient air screening with a calibrated PID has reported background TOV concentrations (<O.1.ppmv) throughout the basement. Such background TOV concentrations in the absence of any detectable odor are considered lines of evidence that demonstrated .the efficacy of the remedial response to remove all contaminated concrete and significantly reduce the volume of impacted soils. The property is currently unoccupied and kept locked as restricting access. As such, based on completed response actions, access and ambient air screening, no Imminent or Substantial Hazards relative to indoor air quality are reported under existing Site conditions. To further test potential vapor entry into the dwelling following soil removal associated with isolated residual soil impacts, a soil vapor probe (SVP-1) was installed through the concrete basement floor as immediately outside the area of excavation and adjacent to the area of residual soil impact to qualify soil vapor concentrations under existing conditions in review of potential for vapor intrusion and inhalation exposures. Two rounds of soil vapor testing were conducted over the reporting period with the benefit of the heating/hot water system operational. Both soil vapor analyses reported all APH concentrations as significantly less than the applicable Residential Sub-Slab Soil Gas Screening in these sampling events. Based on a preponderance of evidence developed from groundwater sampling relative to GW-2 standards, indoor air and infiltration system screening and sub-slab soil vapor APH analysis with the removal of significant soil impacts and impacted flooring, multiple lines of evidence have been developed as demonstrating that soil vapor entry into the occupied dwelling is not likely. As such, this information is extrapolated under the "lines of evidence" rationale to support a fording of No Significant Risk of inhalation exposures at the subject property. ENVIRONMENTAL MONITORING Quarterly groundwater monitoring of TPH and/or EPH/VPH plus target analytes in the existing monitoring wells will be performed in January 2014, in review of potential groundwater impact and exposure risk characterization. Based on the water level and turbidity of samples, both filtered and unfiltered samples may be submitted. Subject to these results, groundwater impacts and exposure risks will be.considered under Method 1 and alternative leaching based standards will be considered under Method 2 towards consideration of project closure objectives as represented herein. NOVEMBER 19,2013 IDLEWILD TRUSTBEAI3-10550 PAGE 22 OF 23 RELEASE ABATEMENT MEASURE STATUS I,RTN 4-24663 Field measurements of groundwater elevations, olfactory and visual observations and the field-testing of pH, dissolved oxygen, conductivity and temperature will be reported on Monitoring Well Sampling Logs. Field inspections will be conducted and documented on "Inspector's Daily Record of Work Progress" reports and remedial response and environmental assessment work will proceed as consistent with the QA/QC Policies of BEA outlined within Appendix D. Personal protection and safety standards for BEA are specified in the Site Specific Health and Safety Plan outlined in Appendix E. CONCLUSIONS The RAM served to remove some 60 cubic yards of source material from the qualified area of significant impact. However, contaminated groundwater marginally above the applicable and strictest GW-1, Method 1 Risk Characterization MW-I as identified on the Site Plan in was reported in the most recent round of groundwater sampling and additional temporal data is necessary to evaluate potential exposures risks under Method 1. Additionally, this additional temporal data will be used to evaluate the potential leaching of residual soil impacts to groundwater under Method 2. An additional quarterly round of groundwater sampling is proposed for January 2014. Based on the results of the January groundwater sampling event and risk evaluation with the benefit of this additional data, a RAM Completion Report and Response Action Outcome (RAO) Statement for project closure will be considered. The findings of this investigation, as .represented herein, set forth the rationale and technical,justification for the LSP Opinions offered, as established by the certifications made on the attached Release Abatement Measure Transmittal Form (BWSC-106) and Remedial Monitoring Report (BWSC-106A).

(BEA) has prepared the following Release Abatement Measure Plan (RAMP), with Supporting Documentation, as a summary of release discovery and subsequent environmental assessment activities conducted since the release of fuel oil was identified in soils underlying the basement floor on May 16, 2013. Formal Release Notification for the 120-Day Reportable Condition was filed on July 10, 2013 after it was determined that groundwater samples collected from on-site groundwater monitoring wells reported low level petroleum concentrations less than the applicable RCGW-1 Reportable Concentrations and the GW-1, Method 1 - Risk Characterization standards. Following Release Notification, Release Tracking Number (RTN) 4-24663 was assigned to the Site towards the preparation and filing of the following RAM Plan for the implementation of remedial response actions in accordance with the provisions of 310 CMR 40.0440-0448. This RAMP identifies potential exposure risks to human and environmental receptors and sets forth the planned remedial response actions to mitigate such risks towards achieving a permanent solution to j support project closure. The RAMP specifies the removal of impacted flooring, excavation and recycling of some 60 yards of impacted soils and the subsequent installation of a structure venting system within the excavated area. This sub-slab venting/SVE system will also provide a preferential pathway for the migration of any organic vapors to the outside of the dwelling and facilitate attenuation of any residually impacted soil. The system infrastructure may also be easily retrofitted as a contingency for the introduction of'remedial additives if additional treatment is necessary beyond soil removal. Release discovery was established in connection with an investigation of concrete floor staining and indications of an abandoned underground tank that was conducted by the perspective buyer as part of a real estate transfer. Hand borings were advanced through the 1 EMERGENCY SPILL RESPONSE 6 WASTE SITE CLEANUP 6 SITE ASSESSMENT 6 PERMITTING 6 SEPTIC DESIGN&INSPECTION WATER SUPPLY DEVELOPMENT,OPERATION&MAINTENANCE 0 WASTEWATER TREATMENT,OPERATION&MAINTENANCE JULY 19,2013 IDLEWILD TRUSTBEAI3-10550 r PAGE 2 OF 13 RELEASE ABATEMENT MEASURE PLAN/RTN 4-24663 basement floor of the subject dwelling while investigating abandoned fuel lines adjacent to the. furnace and a separate area of concrete floor staining under the existing aboveground fuel oil storage tank (AST). Laboratory analysis of representative soil samples from both areas reported petroleum hydrocarbon impacts greater than RCS-1 Reportable Concentrations in at least 2 yards of soils as triggering a 120-Day Reportable Condition. Further investigation outside the footprint of the dwelling found an abandoned underground fuel oil storage tank (UST) off the northeast corner of the dwelling. Both the UST and the AST were subsequently removed and further environmental assessment was conducted to qualify appropriate Notification and Remedial Response actions wherein a threat of groundwater impacts was identified in a mapped Potential Drinking Water Source (PDWSA — GW-1). Subsequent soil testing and analysis was used to identify the horizontal and vertical extent of significant soil impacts as between both the interior and exterior tanks wherein two separate historic releases are indicated. Based on the degree of weathering and interviews with the surviving heirs of the owner, these releases are suspected as being more than 10 years old. Groundwater analytical results show low level groundwater impacts in the vicinity of the former UST (MW-1) but not in the down gradient wells. As such, low level groundwater impact appears to be limited to the area of release as will continue to be monitored throughout the RAM investigation. Additionally, the performance of the RAMP relative to the mitigation of potential exposure risks will further be evaluated by end point sampling of soils for EPH/VPH analysis. As dependent upon these results, sub-slab soil vapor sampling may be conducted to evaluate potential vapor entry into the structure if residual volatiles are reported in the VPH analysis. Initial groundwater gauging has established a southwesterly groundwater flow direction with minimal tidal influence. Since monitoring well MW-3 is marginally outside the projected solute pathway from the release area, an additional monitoring well is proposed to be installed further to the west as immediately down gradient and adjacent to the release area as representative of any down gradient impacts or release migration. This well will be sampled within 48 hours of installation and again quarterly in August and October to evaluate seasonal groundwater variations. It is anticipated that soil removal proposed under the RAM can mitigate all significant exposures risks and any potential critical exposure pathways in support of a Class A, Response Action Outcome (RAO) as a permanent solution with a highest degree of confidence. Notwithstanding, no warranty or guarantee of future performance is expressed or implied. It must be recognized that environmental investigations are inherently limited in the sense that conclusions are drawn and recommendations developed from the available information obtained under the context of the regulations and standard of practice at the time of reporting. This work has and will continue to be conducted under direct LSP oversight in a manner consistent with the MCP Response Action Performance Standards (RAPS)pursuant to 310 CMR 40.0191 and the QA/QC policies of BENNETT ENVIRONMENTAL ASSOCIATES, INC. The facts and statements herein are, to the best of our knowledge, a true and accurate representation of the Site activities, remedial response actions and environmental conditions associated with the project and LSP Opinions acknowledged by the certification on the attached BWSC-105 Transmittal Form. JULY 19,2013 IDLEWILD TRUSTBEAI3-10550 PAGE 3 OF 13 RELEASE ABATEMENT MEASURE PLAN/RTN 4-24663 ENVIRONMENTAL CONDITIONS [Refer to Appendix A] The subject property at 142 Fifth Avenue is noted on Barnstable Assessor's Map 245 as Parcel 113 and is located southeast of the intersection of Fifth Ave and Forest Street [Refer to Figure 1] in the Barnstable Village of West Hyannisport. The UTM coordinates for the Site are Northing 4610162m and Easting 390093m. The property contains approximately 0.27 acres of land area and is developed by a one and a half-story residential dwelling and a free-standing garage. The entire property is upland and relatively flat with approximate elevations ranging from 20' NGVD in the northern portion of the property to approximately 18' NGVD along the southern portion. The surrounding area is heavily developed and in similar use as characterized by seasonal and year-round residential properties. Access to the subject property and area of release is unrestricted with high frequency/low intensity of use and children potentially present. The dwelling occupants and visitors to the property are identified as the primary potential human receptors to potential inhalation and dermal contact exposures. Groundwater was encountered at 12-13' below grade surface. Regional groundwater contours indicate a southwesterly flow direction toward a small unnamed stream and Centerville Harbor farther west [Refer to Figure 2]. Site-specific groundwater contours were found to be consistent with local flow direction. Based on groundwater flow direction, the small unnamed stream represents the primary potential environmental receptor in consideration of Method 1 — Risk Characterization for potentially receiving impacted groundwater. Based on the MA DEP Priority Resources Map the subject property is not located within the Zone II Protective Radius of a Public Water Supply (PWS), nor is it located within the Zone A protective radius of any surface water reservoir. The Site is shown as a medium-yield potentially productive aquifer as well as a part of the Sole Source Aquifer designated by the EPA for all of Cape Cod east of the canal. As such, the Site is defined as within a Potential Drinking Water Source Area (PDWSA). The Priority Resources Map shows an area of protected open space southwest of the subject property across Fifth Ave. The Priority Resources,Map also shows salt and freshwater wetlands to the east, west and south of the Site, as well as NHESP Estimated Habitat of Rare Wildlife in Wetland Areas. Based on the PDWSA designation and proximity to groundwater, the. RCGW-1 Reportable Concentrations are applicable per 310 CMR 40.0361, as are the GW-1, GW-2 and GW-3 Method 1 Risk Characterization standards in accordance with 310 CMR 40.0974. Based on residential use and Site conditions including frequency/intensity of use and accessibility of soils, the RCS-1 Reportable Concentrations are applicable per 310 CMR 40.0362, and S-1/S-2/S- 3 (GW-1/GW-2/GW-3), Method 1 — Risk Characterization standards are applicable per 310 CMR 40.0975. These, standards were developed in consideration of potential. ingestion, inhalation, and environmental exposures, and in review of potential leaching of contaminants to groundwater. In review of potential future use of the property, the strictest S-1 (GW-1) criteria are considered under Method 1 Risk Characterization. r JULY 19,2013 IDLEWILD TRUST/BEA13-10550 ' PAGE 4 OF 13 RELEASE ABATEMENT MEASURE PLAN/RTN 4-24663 BACKGROUND [Refer to Appendix B] During a home inspection for a pending real estate transaction, the home inspector noted subsurface copper lines, adjacent to an exterior wall, in the northeastern portion of the basement. BEA was subsequently contracted by the potential buyer's realtor to investigate the utility of the copper lines. As such, BEA personnel traveled to the subject property on May 7, 2013 to investigate the presence of an abandoned UST and to perform hand borings in the area of the copper lines to determine if a release of fuel oil had occurred. Upon arriving at the property, BEA personnel probed the ground adjacent to the northeast corner of the dwelling for signs of an underground tank. A large object, with the approximate dimensions similar to a typical 275- gallon fuel tank was located approximately 2' below grade in this location. A hole was dug and it was confirmed that the object was a steel UST. BEA personnel then went to the basement to perform hand borings to assess subsurface soils. Upon entering the basement, petroleum staining was observed beneath the existing AST servicing the heating system, representing another possible release of fuel oil to the subsurface. As such, a series of hand borings were advanced to investigate subsurface conditions below the basement slab (Refer to Site Plan). BEA conducted two hand borings (HB-1 and HB-IA) in the area of the AST. HB-1 was angled beneath the tank to the west, perpendicular to the interior basement wall. HB-lA was angled beneath the tank to the northwest, towards the corner of two interior basement walls, where the staining was greatest. Hand boring HB-2 was advanced in the northeastern portion of the basement adjacent to the subsurface copper lines. The hand borings were advanced with a J Pp g stainless steel bucket auger with soil samples collected in 2' intervals. The samples were then placed in 250-milliliter glass jars with aluminum septa and agitated to develop organic vapors. The samples were subsequently screened by "jar headspace method" with a PID [ThermoEnvironmental 580B OVM (10.8 eV lamp)] as consistent with the Interim Soils Policy (WSC-94-400). PID screening reported elevated organic vapor concentrations < 30 parts per million by volume (ppmv) in HB-1/HB-lA and < 67 ppmv in HB-2. BEA field preserved soil samples HB-IA:2-4' and HB-2:4-6' on ice in a cooler for MA Certified laboratory analysis of risk-based extractable petroleum hydrocarbon (EPH) and target polynuclear aromatic hydrocarbon(PAH) concentrations. Laboratory analysis reported concentrations of fractional C9-C18 Aliphatics and CI I-C22 Aromatics greater than the applicable RCS-1 Reportable Concentrations in both soil samples submitted. As such, laboratory analytical had demonstrated significant petroleum hydrocarbon impact in more than two yards of soil, and, in the absence of evidence demonstrating a sudden release, or elevated PID readings (>100. ppmv) in soils, a 120-Day Release Notification requirement was triggered as the basis of remedial response liability.

ENVIRONMENTAL ASSESSMENT/PREI.,IMINARY RESPONSE [Refer to Appendix B] Soil On June 5, 2013, BEA returned to the site to oversee the removal of both tanks and to perform hand borings below the basement floor to define extent and magnitude of significant fuel oil impact. Upon arrival at the property, Tank Removal Services (TRS) was preparing to pump the contents of the 275-gallon AST in the basement of subject dwelling. The oil was pumped from the tank by Autobody Solvent Recovery Corp. and the tank was then removed from the basement to facilitate soil assessment activities. BEA personnel then used a concrete coring bit JULY 19,2013 IDLEWILD TRUST/BEA13-10550 PAGE 6 OF 13 RELEASE ABATEMENT MEASURE PLAN/RTN 4-24663 to drill four (4) holes in the basement floor to advance hand borings HB-3 through HB-6 to depth. The hand borings were again advanced with a stainless steel bucket auger with soil samples collected in 2' intervals. The samples were subsequently screened by "jar headspace method" with a PID. Refusal was met in HB-3 at 1' below grade. Concentrations of organic vapors in hand borings HB-4 through HB-6 ranged from Non-Detect (ND) to 58 ppmv, with the highest headspace concentrations in hand boring HB-4. TRS personnel then began to prepare the abandoned UST for removal. The UST was P g P P uncovered with a backhoe and was cut open to remove the contents. According to TRS personnel the tank was full of oily water. Autobody Solvent Recovery Corp. then pumped out the tank and transported the contents of both tanks (350 gallons oil/water)to Murphy's Waste Oil Service, Inc. in Woburn, MA (see Manifest provided for reference in Appendix C). The tank was then removed from the ground and inspected for integrity. Barnstable Fire Department personnel (Fire Prevention Officer Don Chase)were at the Site to witness the removal of the tank from the tank grave. Upon inspecting the tank, substantial corrosion was noted with signs of wetness evident on the exterior of the tank. BEA personnel proceeded to collect samples from the tank grave for field screening by jar headspace method. Low organic vapor concentrations (<2.0 ppmv) were reported by field screening the soil samples collected from the bottom of hole of the UST grave. BEA personnel then proceeded to perform hand boring HB-8 in the bottom of the UST grave to approximately 12' below grade, where groundwater was encountered. Field screening of the soil samples from HB-8 ranged from ND in the 5-T interval to 64 ppmv in the 9- 10' interval. BEA personnel performed two additional hand borings, HB-9 and HB-10, in the basement of the subject dwelling to further define the eastern and southern extents of soil impact. Field screening of soil samples from HB-9 ranged from ND in the 0-2' interval to 58 ppmv in the 24 interval. In HB-10 all concentrations from field screening were reported as ND. BEA personnel subsequently cleaned up the basement of the dwelling and departed the Site with the preserved samples for extractable petroleum hydrocarbon (EPH + PAHs) and volatile petroleum hydrocarbon(VPH+BTEX) laboratory analyses. Laboratory analytical results, received June 14, 2013, reported fractional C9-C18 Aliphatics concentrations greater than the strictest S-1/GW-1 Method 1 Risk Characterization Standards in samples collected from hand borings HB-4, HB-7 and HB-8. Cl l-C22 Aromatics concentrations also exceeded the S-1/GW-1 Standards in the sample collected from HB-8: 9-10'. In addition, target analytes were reported above the S-1/GW-1 Standards in HB-4, HB-7, HB-8 and HB-9.

BEA personnel directed Jenkins Well Drilling in the advancement of TB-11, TB-12 and TB-13 towards the installation of monitoring wells MW-1, MW-2 and MW-3, respectively. Test Boring TB-11 was advanced off the northeast corner of the dwelling, in the area of the former UST; TB-12 was advanced south of the dwelling and TB-13 was advanced southwest of the dwelling (Refer to Site Plan). The wells were finished in water-tight road boxes with locking gripper plugs. Top-of-casing elevations were also surveyed to a common vertical datum in review of static water level elevations towards calculating local groundwater flow. Field headspace screening of soil samples collected from the test borings reported low concentrations of organic vapors (<2.0) with the exception of TB-11/MW-1 where, in the 17-19' interval a concentration of 18.2 ppmv was reported. A discrete sample at 19' bgs reported a concentration of 38.7 ppmv. Representative soil samples TB-11: 11-13', TB-11@19' and TB- 13:11-13'were prepared and forwarded to a certified laboratory for confirmatory EPH with target PAH analysis.

Laboratory analysis has confirmed the presence of C 11-C22 fractional r JULY 19,2013 IDLEWILD TRUST/BEA13-10550 PAGE 10 OF 13 RELEASE ABATEMENT MEASURE PLAN/RTN 4-24663 aromatics and C9-C18 Aliphatics, as well as 2-methylnaphthalene, as exceeding the RCS-1 Reportable Concentrations as well as the S-1/GW-1 Method 1 —Risk Characterization standards. As such, remedial response and waste site cleanup activities are prescribed under the RAMP to absolve potential exposure risks and to meet regulatory closure objective without limitation of activities or use of the property. Groundwater As presented, the RCGW-1 Reportable Concentrations, as well as the GW-1, GW-2 and GW-3 groundwater categories are applicable in consideration of Method 1 Risk Characterization. These standards were developed to evaluate potential ingestion (GW-1), inhalation (GW-2) and environmental (GW-3) exposures. Groundwater sampling and associated laboratory analysis have reported no significant impacts above GW-1 Standards in any of the on-site monitoring wells. However, based on groundwater gauging and site-specific groundwater flow calculations it has been determined that there are no groundwater monitoring wells that are within a definitively down gradient position. As such, one additional monitoring well is prescribed within the RAMP. Indoor Air Indoor ambient air quality within the living space of the residence was screened during the initial Site inspection on May 5, 2013 and has been monitored during subsequent Site visits. The screening has been conducted utilizing a pre-calibrated PID with a 10.6 or 11.8eV lamp. Each indoor air screening event has reported no detectable petroleum odors and background TOV concentrations (<O.1 ppmv) in the dwelling basement. No additional testing has been conducted at this time as the dwelling is currently unoccupied. Indoor air quality will continue to be monitored duringsubsequent Site inspections for q Y q P worker safety. During soil removal operations a vapor barrier will be installed between the Y g p P basement and living area with active ventilation provided. As part of the RAM, all impacted flooring will be removed and replaced inside the dwelling as eliminating interior sources of organic vapors. Pursuant to the Interim Final Vapor Intrusion Guidance (Policy WSC-11-435), as well as anticipated revisions to the MCP, Air-phase Petroleum Hydrocarbon (APH) testing of representative soil vapor beneath the concrete basement slab will supplement the PID screening towards the development of multiple lines of evidence to evaluate potential vapor intrusion and inhalation exposure risks, should residual volatile organic compounds be present within the prescribed setbacks as framed in the provisions of 310 CMR 40.0942(l)(d). Imminent Hazard Evaluation Based on the assessment activities conducted to date, which indicate that all significant fuel oil impacts remain at more than 9' below grade or beneath the footprint of dwelling, at which time the dwelling has been largely uninhabited, no Imminent or Substantial Hazards have been identified at the Site. Groundwater monitoring has reported no significant impacts associated with the subject release, and the most recent indoor air quality screening has reported no TOV concentrations within the dwelling above the sensitivity of the instrument (<0.1 ppmv). f DULY 19,2013 IDLEWILD TRUST/BEA13-10550 PAGE 11 OF 13 RELEASE ABATEMENT MEASURE PLAN/RTN 4-24663 Monitoring of groundwater, indoor air and soil vapor will continue in review of potential impacts and risk characterization to evaluate potential hazards towards development of a preponderance of physical evidence in qualifying exposure risks and demonstrating No Significant Risk. RELEASE ABATEMENT MEASURE PLAN [Refer to Appendix El The information from the assessment of current soil and groundwater conditions was used to develop a remedial strategy for the, excavation of significantly impacted soils from the identified release area noted on the site plan. This remedial strategy calls for the removal of the concrete floor and impacted subsurface soils to a depth of up to 6' below the basement floor. It is anticipated that as much of 60 cubic yards of impacted soil may be generated. Temporary structural support of the chimney and northeast corner of the subject building will be installed by a licensed contractor with appropriate permitting. Prior to the beginning of work the furnace will be removed. Subsequent to the shoring of the building, the environmental contractor will break up the basement floor and properly dispose of any and all impacted concrete. The contractor will then use an excavator to segregate and stockpile clean overburden material adjacent to the exterior basement walls. Soil removal will then be advanced to depth from the north to the south. Soils will be transported off site under an approved Bill of Lading for direct loading and transportation to Aggregate Industries South Dennis asphalt batching facility. Following the removal of significant soil impact as anticipated in the beginning of August 2013, confirmatory end-point soil samples will be collected for risk-based EPH/VPH analysis, or for TPH analysis as a cost saving measure wherein field-testing indicates petroleum and volatile impacts are clearly absent. After field screening has indicated that risk based closure objectives have been met, a subsurface sub-slab venting/SVE system will be constructed and installed in the excavated area of release. The venting system will be constructed of 4 x 4"perforated PVC pipe laterals, as set in washed stone along the bottom-of-hole area. A 4" solid piece of PVC riser will be plumbed to the lateral components and connected to a wind turbine for the passive venting of residual volatile petroleum compounds. The venting system will also provide the flexibility to deliver remedial additives, as may be necessary to mitigate significant residual soil impacts or for any groundwater treatment. If residual volatile compounds are reported in the end point samples as within 6' horizontally and 10' vertically of the basement floor, a soil vapor probe will be installed and tested for APH. APH analytical results will be compared with the sub-slab screening values set forth in the Interim Final Vapor Intrusion Guidance document (Policy WSC-11-435). This testing may be repeated to establish the prescribed "lines of evidence" rationale to evaluate potential vapor entry into the occupied structure and related inhalation exposures. The monitoring wells will be sampled quarterly in August and October 2013 following soil removal. The quarterly groundwater analysis will be used to evaluate any residual petroleum hydrocarbon impacts to groundwater. The further treatment of soils and/or impacted groundwater will be evaluated from the results of end-point soil sampling and fiiture quarterly groundwater assessment. Specifications of potential remedial equipment, operations and maintenance, or use 1 2 -1 JULY 9, 013 IDLEWII,D TRUSTBEAI3 0550 PAGE 12 OF 13 RELEASE ABATEMENT MEASURE PLAN/RTN 4-24663 of any remedial additives will be represented as a modification of the RAM, if applicable, to be reported in subsequent RAM Status (RAMS) reports. All such work will be compiled on "Inspector's Daily Record of Work Progress"reports and documented in a RAM Status Report or RAM Completion Report to be submitted within 120 days of this filing. CONCLUSIONS The Release Abatement Measure Plan, represented by this filing, proposes the excavation and disposal of up to 30 cubic yards of significantly impacted soils from the release area identified on the Site Plan in Appendix A. Under the RAM Plan, BEA will direct the segregation of clean overburden material surrounding the dwelling to accommodate the excavation and disposal of contaminated soils. Field PID screening and Dexsil testing will be used by BEA personnel to provide technical assistance and direct excavation operations. A subsurface venting system will be constructed and set in washed stone aggregate prior to final restoration for venting of residual petroleum hydrocarbons, and/or future remedial additive applications if necessary. This work is intended to eliminate the contaminant source and associated exposure risks to identified human and environmental receptors towards achieving a condition of No Significant Risk in support of a permanent solution. This work is scheduled to begin in the beginning of August 2013. A RAM Status Report or RAM Completion Report with Response Action Outcome (RAO) will be submitted within 120 days of this filing. Any subsequent RAM Status Reports will be filed every six months thereafter until a preponderance of physical evidence supports a condition of "No Significant Risk" and RAO objectives are met as supporting an RAM Completion Report. The findings of this investigation, as represented herein, set forth the rationale and technical justification for the LSP Opinions offered, as established by the certifications made on the attached Release Abatement Measure Transmittal Form(BWSC-106). The LSP Opinions are based on available data and regulations in effect at the time of this reporting specific to the subject Site.
