(BEA) has prepared the following written Immediate Response Action Completion and Permanent Solution Statement (IRAC-PSS) report with Supporting Documentation, as a summary of the response actions and environmental assessment activities performed since release discovery on February 25, 2017. Immediate Response Actions were implemented to address significant impacts and exposure risks associated with the sudden release of up to 250 gallons of home heating oil from an exterior aboveground storage tank (AST) at the subject property. Based on the review and validation of soil, groundwater and indoor air analytical results following Remedial Response Actions, an evaluation of potential exposure risk to identified human and environmental receptors has documented a condition of No Significant Risk without conditions, in support of regulatory project closure, as framed within the provisions of the MA Contingency Plan (MCP), regulated under 310 CMR 40.0000. This work proceeded 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 certifications on the enclosed BWSC-104 and BWSC-105 forms. ABSTRACT/OVERVIEW During the initial response to the fuel oil release, the subject tank was secured against further leakage, and absorbents were applied to the concrete slab beneath the tank. Soil and groundwater assessment was initially carried out by the Insurer's consultant. Subsequent to 1 EMERGENCY SPILL RESPONSE ® WASTE SITE CLEANUP ® SITE ASSESSMENT O PERMITTING 6 SEPTIC DESIGN&INSPECTION. WATER SUPPLY DEVELOPMENT,OPERATION&MAINTENANCE 6 WASTEWATER TREATMENT,OPERATION&MAINTENANCE i DECEMBER 14,2017 ENNES-2 GENERAL PATTON DR.HYANNISBEAI7-11006 PAGE 2 OF 28 IRAC-PSS,RTN 4-26544 reviewing the work performed by the Insurer's consultant, BEA believed the premise to deny coverage was flawed by selective sampling. BEA, under limited authorization, conducted additional soil and groundwater testing on behalf of the property owners, who had filed for Financial Inability. This additional work reported gross impact in soils from the surface to approximately 15' below grade, as well as groundwater impact above the applicable GW-1, Method 1 Risk Characterization Standards. Based on these results, the Insurer extended insurance coverage and BEA was engaged by the property owner to continue remedial response work, under the Immediate Response Action (RTN 4-26544). As such, the initial IRA Plan filing was delayed, and not filed until June 12, 2017. Supplemental assessment of soils was conducted and remedial response actions were proposed, including the removal of impacted soils within a 16' (L) x 10' (W) area to up to depth of 15' bgs (89 yards), as well as the addition of up to 400 lbs. of Regenesis© RegenOx Part A mixed into soils in the bottom of the excavation. An infiltration system, constructed of 4" perforated PVC and set in washed stone aggregate was also proposed, to provide flexibility for the potential addition of RegenOx Part B, to activate the remedial additives for In-situ Chemical Oxidation(ISCO). Assessment of groundwater included the installation and testing of three groundwater monitoring wells, which identified minor groundwater impact above the Method-1 GW-1 Risk Characterization Standards, in the immediate vicinity of the release. Based on the environmental assessment work conducted, structural engineering plans were prepared for the construction of a shoring box to facilitate soil removal to the proposed depth. Soil removal activities were performed in August and September of 2017 and resulted in the removal of 89.9 tons (60 cubic yards �:) of petroleum contaminated soil. Prior to backfilling, 400 pounds of RegenOx Part A remedial additive were mixed into soils in the bottom of the excavation, as a contingency for potential in-situ chemical oxidation treatment (ISCO). Based on the soil and groundwater results collected subsequent to soil removal, the RegenOx Part B activator for ISCO treatment was never applied, as it was not deemed necessary to meet cleanup objectives. With the exception of two bottom of hole soil samples and a single sidewall sample, laboratory analysis has reported all soil samples as less than the strictest S-1 (GW-1), Method 1 Risk Characterization standards. A series of Exposure Point Concentrations (EPCs) were subsequently developed to evaluate exposure risks to select soil categories under current and foreseeable future use. The EPCs reported No Significant Risk under the applicable and most stringent Method 1 Risk Characterization Standards. As a conservative measure in consideration of potential exposure risk, the specific area of greatest residual soil impact was treated as a potential hotspot. The highest EPH/VPH and target analyte concentrations reported from residual impact (Zone B BOH(S): 15-16) were input into the Method 3 Resident — Soil Short Form, as a "worst case" discrete exposure. The Method 3 Short Form reported both Chronic and Sub-Chronic Hazard Indexes (HI) less than 1 and the ELCR reported as less than 1/100,000 (10-5), indicating a condition of No Significant Risk under Method 3, relative to residual soil impacts below the basement floor of the subject dwelling. DECEMBER 14,2017 ENNES-2 GENERAL PATTON DR.HYANNISBEAI7-11006 PAGE 3 OF 28 IRAC-PSS,RTN 4-26544 As such, soil removal has effectively mitigated the contaminant source and now represents a condition of No Significant Risk based on a preponderance of evidence and evaluation of laboratory analytical under Method 1, as supported Method 3 considerations of discrete data sets. Two quarterly rounds of groundwater monitoring, subsequent to soil removal activities, report all petroleum hydrocarbon and target analyte concentrations as Non-Detect (ND), or below the most stringent GW-1, Method 1 Risk Characterization standards. Based on concentrations of residual volatile organic compounds (VOCs) in soil, within the framed setbacks pursuant to 310 CMR 40.0942(1) (d) and the Vapor Intrusion Guidance (Policy#WSC- 16-435), soil vapor testing was also conducted. Results of soil vapor testing reported concentrations of air-phase petroleum hydrocarbons (APH) fractions above the Residential Sub- Slab Soil Gas Screening Values (RSSGV), indicating the potential for vapor intrusion into indoor air. Therefore, indoor air sampling was conducted at three locations throughout the dwelling. Results of indoor air sampling reported all concentrations of fractional APH and target analytes below the applicable residential indoor air standards in each location tested. As such, based on the Immediate Response Actions and environmental monitoring performed, laboratory analytical and a preponderance of physical evidence, under Method 1 and Method 3 Risk Characterization, these measures have demonstrated a condition of No Significant Risk to support the IRA Completion and Permanent Solution Statements for project closure. ENVIRONMENTAL CONDITIONS [Refer to Appendix A] Subject Property The subject property, located at 2 General Patton Drive is located approximately 100 feet southwest of the intersection of Bearses Way and General Patton Drive in the village of Hyannis in Barnstable, MA (Latitude 410 39' 35" N and Longitude 700 17' 46"W) [Refer to Figure 1]. The property contains 0.19 acres of land area and is developed by a one-story ranch-style dwelling constructed in 1950. The Defined Site, as that portion of the subject property where fuel oil was released or came to be located, is on the north central side (rear) of the dwelling as a small portion of the subject property as defined below. The surrounding area is heavily developed in similar high density residential use, with commercial businesses to the north along Falmouth Road (Route 28). Access to the subject property is unrestricted, with high frequency/high intensity of use, and children potentially present. Access to the area of release is also unrestricted, with high frequency/high intensity of use. The occupants, on-site workers and visitors to the property are identified as the primary human receptors to potential exposure risks associated with soil impacts and groundwater, impacts. The subject property occupants and abutters are included relative to the potential exposures associated with off- site migration of groundwater. The primary environmental receptor is Hyannis Inner Harbor, located approximately one mile south east of the site. Hydrologic references indicate groundwater exists below elevation 30' NGVD, within 20' of DECEMBER 14,2017 ENNES-2 GENERAL PATTON DR.HYANNISBEAI7-11006 PAGE 4 OF 28 IRAC-PSS,RTN 4-26544 ground surface. Regional groundwater contours indicate a southeasterly flow direction towards the Hyannis Inner Harbor, located approximately one-mile southeast of the Site [Refer to Figure 2]. Through subsurface investigations performed at the site, groundwater has been measured at approximately 21' below grade, with groundwater flow to the southeast, consistent with regional flow. According to the Mass GIS Priority Resource Map,the subject property is not located within the Zone II Protective Radius of a Public Water Supply (PWS) well, nor is it located within the Zone A Protective Radius of any surface water reservoir. The Site and immediately surrounding area to the south and west are shown within a Medium-Yield Potentially-productive aquifer and within an EPA-designated sole source aquifer, as is all land area east of the Cape Cod Canal. As such, the Site and surrounding area are located within a Potential Drinking Water Source Area (PDWSA). A Non-Potential Drinking Water Source Area (NPDWSA) boundary is shown north and immediately east of the site, across Bearses Way. The NPDWSA is also located further to the south and west of the site. It is also noted that the Barnstable Wastewater Treatment facility plant is located within 500' of the subject property in an up-gradient location, and that groundwater quality from the plant is mapped in this area as degrading groundwater quality as a drinking water source [Refer to Figure 3]. As such, based on the location of the property within a PDWSA and the depth to groundwater, the Site is currently subject to the GW-1, Method 1 Risk Characterization standards in consideration of "significant risk" pursuant to 310 CMR 40.0932. Based on the depth to groundwater (> 15'), it appears that the GW-2 standards are not applicable but be considered in the "lines of evidence" evaluation of vapor entry under Method 3. Additionally, based on potential significant environmental impacts and dermal contact exposures, the GW-3 Method 1 Risk Characterization standards do apply and are considered. However, based on the location of the subject property as one-half mile down-gradient of the Town of Barnstable Wastewater Treatment Facility, it seems unlikely that the area would be developed as a drinking water source. As such, BEA believes that the exposure risk from ingestion (GW-1) is overstated and not a foreseeable exposure risk. The MA DEP BWSC GIS mapping shows a Non-Potential Drinking Water Source Area (NPDWSA) across Bearses Way 200 feet northeast of the subject property. The NPDWSA continues southeast and southwest of the subject. property, surrounding the Site on three sides. Based on the similarity of the subject property to those surrounding properties (URD: Urban High Density Residential) the MA DEP "Non-Potential Drinking Water Source Area" Policy WSC-97- 701, allows for the subject property to be included in the NPDWSA mapping as excluding the drinking water ingestion and shower model inhalation exposures under the Method 1, GW-1 criteria Based on Site conditions relative to frequency/intensity of use and accessibility of soils, the S-1/S-2/S-3 (GW-3) Method 1 — Risk Characterization standards are applicable to soil impacts in the qualification of "significant risk", in accordance with the provisions of 310 CMR 40.0975. Furthermore, in consideration of all potential foreseeable future exposures, the most restrictive S- 1/GW-1, Method 1, Risk Characterization standard is consideration as a conservation measure of potential ingestion, inhalation and dermal contact exposures and significant environmental impacts, relative to consideration of Significant Risk as defined within the MCP. Site Description The Defined Site, as that portion of the subject property where oil or hazardous materials (OHM) were released, migrated or otherwise came to be located, is a portion of the subject property DECEMBER 14,2017 ENNES-2 GENERAL PATTON DR.HYANNIS/BEA17-11006 PAGE 5 OF 28 IRAC-PSS,RTN 4-26544 located adjacent to and beneath the western portion of the subject dwelling in the northern-central portion of the property. The Defined Site is roughly centered on the release a rectangular area approximately 22' (L) x 18' (W), covering some 400 SF of land area [Refer to Site Plan—Appendix A]. BACKGROUND/RELEASE DISCOVERY The morning of February 25, 2017, the homeowner, Ms. Rosemarie Ennes observed a petroleum odor at the rear of the building. Upon checking the outside aboveground fuel oil storage tank (AST), Ms. Ennes observed oil actively leaking from the tank. Ms. Ennes immediately called her fuel oil supplier (Scudder Taylor) and the Barnstable Health Department, both of whom responded to the property. Scudder Taylor personnel were able to stop the leak with a magnetic patch; however, the fuel gauge indicated the tank was already empty. Based on the date the tank was last filled (139 gallons on 2/23/17), with a minimal amount of oil remaining in the tank, it is estimated that the tank released up to 250 gallons before the leak was stopped. Barnstable Health Department personnel (Donna Miorandi, Health Agent) contacted the Hyannis Fire Department and MA DEP to report the sudden release of fuel oil. MA DEP personnel (Peter Russel) then contacted Ms. Ennes to consult with the homeowner regarding remedial response liability under the Massachusetts Contingency Plan (MCP). Ms. Ennes indicated that she would contact emergency response contractor NRC/ENPRO to request that they respond to the release. MA DEP personnel later responded to the release to meet with the homeowner and to assess the release. MA DEP records (BWSC-102) indicate that there was a mild odor near the tank, but no odor in the basement of the dwelling and no evidence of impact to a storm drain at the corner of the property. MA DEP personnel later departed the scene upon the arrival of the NRC/ENPRO crew, who swept up the granular absorbent applied by the Hyannis Fire Department and constructed a poly-sheeting tent over the impacted area. Ms. Ennes contacted BEA on March 17, 2017, to request LSP oversight, as instructed by MA DEP personnel. BEA Licensed Site Professional (LSP) David Bennett requested to be kept updated subsequent to scheduled field testing provided by the Insurer. ENVIRONMENTAL ASSESSMENT/PRELIMINARY RESPONSE [Refer to Appendix B] EnviroTrac, Ltd. was later contracted to investigate the release by the homeowner's Insurer (Liberty Mutual). On March 22, 2017, EnviroTrac personnel performed a single test boring approximately 4' outside the area of soil staining and installed a single groundwater monitoring well. Continuous soil sampling and PID screening was conducted from the surface to the groundwater with a maximum PID reading of 160 ppmv reported in the 8-10' interval and 54.3 ppmv at the groundwater interface at 23' below grade. A single soil sample (MW-1 24') was submitted to SGS Accutest Lab for EPH/4PAHs and VPH/BTEX analysis. Groundwater from monitoring well (MW-1) was also collected and submitted to Accutest for EPHAPAHs and VPH/BTEX analysis. DECEMBER 14,2017 ENNES—2 GENERAL PATTON DR.HYANNISBEAI7-11006 PAGE 6 OF 28 IRAC-PSS,RTN 4-26544 - — -- 1 t ► f � �1 ; a � - 1 i; Photo 1:View of subject AST with monitoring well MW-1 in foreground. Results of soil analysis reported low concentrations of fractional EPH and VPH below the most stringent S-1/GW-1 Method 1 Risk Characterization Standards. Results of groundwater analysis reported low concentrations of target PAHs below the GW-1 Method 1 Risk Characterization Standards. Upon review of the data, BEA responded directly to Liberty Mutual regarding the testing performed. BEA believed that the testing was flawed, based on the location of the test boring and monitoring well (MW-1), which was installed outside of the release area and in a location up-gradient of regional groundwater flow. In addition, it was noted that the only soil sample submitted (MW-1 24') was collected from below the groundwater interface, and did not correspond with the elevated PID readings observed. BEA, acting outside the role of LSP, believed that the volume of oil released in sandy soils would be present from the surface to depth and threaten groundwater impact. However, the sample selection for soil and groundwater testing did not consider the spatial location of release or the solute fate of groundwater, and did not give a clear picture of environmental conditions to form the basis of Insurer's decision. On behalf of the property owners, BEA then requested they reconsider insurance coverage based on the flawed assessment performed by their consultant. The Insurer declined to reconsider coverage and took the position that no coverage would be afforded to the Insured unless groundwater impact was documented above GW-1 Standards. Upon consultation with the property owner, additional assessment activities were scheduled to qualify previous testing results. BEA arranged for the AST to be removed for clear access to the area of release for subsequent testing, and on April 28, 2017, BEA personnel performed soil borings and monitoring well installation activities at the property. DECEMBER 14,2017 ENNES-2 GENERAL PATTON DR.HYANNIS/BEA17-11006 PAGE 7 OF 28 IRAC-PSS,RTN 4-26544 Two soil borings were performed at the site to determine the general nature and extent of impacted soils. Test boring TB-2 was performed within the release area, directly below the former AST. Test boring TB-3 was performed in the driveway of the subject dwelling on the opposite side of the house in a down-gradient location. Field screening of soil samples collected from TB-2 reported organic vapor concentrations ranging from 157 to 199 ppmv increasing with depth up to and including the 12-16' interval. Soil samples collected from below 16' exhibited decreased PID readings from 8-15 ppmv, with slight increase at groundwater interface at approximately 20' below grade. Soil samples collected from TB-3 were down-gradient of the release area, reported no concentrations of organic vapors above background throughout the borehole section. Monitoring wells were set at each of these locations. ,1 r S' t Photo 2: Location of BEA test boring (TB-2) and the monitoring well (MW-2) as within release area under former above ground oil tank. A single soil sample from the area of impact (TB-2:12-16) was prepared and.submitted to R.I. Analytical laboratory for EPH/4 target PAHs and VPH/BTEX analysis. Analytical results, received May 5, .2017, reported EPH/PAH and VPH/BTEX concentrations greater than the applicable Method 1 Risk Characterization standards as considers potential leaching to groundwater. The analytical results are summarized below in Table 1.

Samples were collected from MW-2(TB-2) and MW-3(TB-3) and submitted to a MA Certified lab for EPH/PAHs and VPH/BTEX analyses. Laboratory analytical results, received May 11, 2017, reported concentrations of EPH/PAHs and VPH/BTEX in MW-2, including fractional C9-Cl0 Aromatics, Cll-C22 Aromatics and 2- Methylnaphthalene above the applicable GW-1 Method 1 Risk Characterization Standards. No concentrations of EPH/PAHs or VPH/BTEX were reported in down-gradient monitoring well MW- 3. The analytical results for the groundwater samples are summarized below in Table 2._ The Insurer was subsequently contacted and provided with the field reports and analytical results for the soil and groundwater testing conducted, regarding the concentrations of soil and groundwater impact reported, in reconsideration of coverage under the homeowner policy. The property owner later contacted BEA to notify them that the Insurer had changed their position and was now offering coverage of the release, as a covered loss. BEA subsequently received full engagement to provide LSP Oversight and professional services toward development and implementation of an IRA Plan. On May 30, 2017, BEA personnel returned to the site to collect additional data on the lateral extent of soil impact. BEA personnel performed three hand borings in the vicinity of the release area in an attempt to determine the limits of significant impact. Hand boring HB-1 was advanced northeast of the release area, HB-2 was advanced southwest of the release area, and HB-3 was advanced northwest of the release area. Refusal was met at 10' below grade in HB-1, and 6' below grade in HB-2 and HB-3, due to rocks. Low PID readings (<3 ppmv) were reported in HB-1. Elevated PID readings from 40.3 ppmv to 20.4 ppmv were reported in HB-2, decreasing with depth. No PID readings were reported in HB-3 above the instrument detection limit (Non-Detect). Based on the limited amount of data collected from relatively shallow depths, no samples were submitted to the laboratory from these assessment activities. Nevertheless, this information was used to re- DECEMBER 14,2017 ENNES-2 GENERAL PATTON DR.HYANNISBEAI7-11006 PAGE 9 OF 28 IRAC-PSS,RTN 4-26544 . define the area of soil impact for the proposed soil removal activities. Based on the refusals encountered during the hand borings, additional test borings were proposed in order to collect soil samples at greater depths.

The IRAP called for the mechanical removal of up to 100 cubic yards of impacted soils in a 15' .x 10' area to 15' deep. As a contingency against residual impact, Part A of the two-part Regenesis RegenOx ® in-situ chemical oxidant (ISCO) would be applied to soils in the bottom of hole area, with an infiltration system installed prior to backfilling, for the potential application of Part B. Soil samples collected at the extent of the excavation would be collected for laboratory analysis. Groundwater sampling with laboratory analysis would continue quarterly to monitor groundwater conditions at the site. SUPPLEMENTAL ASSESSMENT On June 22, 2017, BEA returned to the site with Bronson Drilling of Winchester, MA, to install two additional groundwater monitoring wells and to perform additional soil assessment in the release area. Test boring TB-4 was advanced in the front of the house, in a down-gradient location, and was completed as monitoring well MW-4. Test borings TB-5 and TB-6 were advanced to the north and south of the release area, respectively. Test boring TB-7 was advanced west of the release area and was completed in an up-gradient location, as monitoring well MW-5. The test borings were performed using a direct-push-type drilling rig. Four-foot composite soil samples were collected in Shelby tubes and then placed in an 8-ounce glass jar, sealed with an aluminum septum, then agitated to develop organic vapors. Each sample was subsequently screened with a PID by "jar headspace method" consistent with the Interim Soils Policy (WSC-94-400). Field screening of a soil sample collected from TB-4 at the groundwater interface reported no concentrations of organic DECEMBER 14,2017 ENNES-2 GENERAL PATTON DR.HYANNISBEAI7-11006 PAGE 10 OF 28 IRAC-PSS,RTN 4-26544 vapors above the instrument detection limit (Non-Detect). Field screening from Test boring TB-5 reported organic vapor concentrations ranging from 22.8 to 23.3 from 6-12' below grade, 154 in the 12-16' interval, 0.3 ppmv in the 16-20' interval, and ND in the 20-24' interval at the groundwater interface. Soil samples collected from TB-6 and TB-7 reported no concentrations of organic vapors above background. Based on its location within the release area, monitoring well MW-2 was also checked for the accumulation of light non-aqueous phase liquid (LNAPL) during this site visit. A sample of water was collected with a dedicated bailer and emptied into a glass jar. Small globules of LNAPL were observed in the water sample after emptying the in the jar. Three soil samples from TB-5 (TB-5: 6-12', TB-5: 12-16' and TB-5: 16-20') and a single soil sample from TB-6 (TB-6: .6-16') were submitted to a MA certified laboratory for EPH/PAH and VPH/BTEX analysis. The results, received on July 3, 2017 reported trace concentration of fractional VPH and EPH, below the most stringent S-1/GW-1 Method 1 Standards, in the TB-5: 12- 16' sample. The remaining soil samples reported all concentrations of EPH/PAHs and VPH/BTEX as Non-Detect. These results confirmed the proposed extent of soil removal in a 16' x 10' area. The results are summarized below in Table 3.

During the sampling event, the wells were purged and sampled via low-flow methodology, wherein the samples were collected for EPH/VPH and target analyte concentrations upon meeting purge requirements and the stabilization of field parameters (pH, Dissolved Oxygen, Conductivity, Temperature). The samples were collected in appropriately preserved laboratory containers and placed on ice in a cooler. The top-of-casing elevations of all monitoring wells were then surveyed to a common vertical datum, towards the qualification of local groundwater flow direction. Static water level measurements demonstrated a site-specific groundwater flow to the southeast, consistent with regional flow. Based on the groundwater flow direction calculated, monitoring wells MW-4 and MW-3 were located in down-gradient locations. Monitoring well MW-2 was again checked for the accumulation of LNAPL. An interface probe was used to check for accumulated product thickness. No measurable product thickness was noted. A sample of water was again collected for a visual check with a heavy petroleum sheen observed on the sample collected. Prior to departing the site, an absorbent sock was installed in monitoring well MW-2 for the passive collection of product. Laboratory analytical results were received on July 11, 2017. The results reported all EPH/PAH and VPHBTEX concentrations in monitoring wells MW-4 and MW-5 as Non-Detect, wherein the reporting limits of the analyses were less than the applicable GW-1 and GW-3 Method 1 Risk Characterization standards. BEA subsequently requested bids from three different environmental contractors for the proposed scope of work based on the assessment data collected. The clients selected Frank Corp. Environmental Services to perform the work based on the provided bid. The IRA Status I Report was filed on August 8, 2017. IMMEDIATE RESPONSE ACTIONS [Refer to Appendix B] Based on the IRA Plan outlining the mechanical removal of up to 100 cubic yards of impacted soil and the subsequent application of Part A of the RegenOx remedial additive, site work for soil removal activities commenced in early August 2017. The area of impacted soils was located at the intersection of an addition to the dwelling, wherein the northern portion of the dwelling was on a full foundation and the southern portion was on a concrete slab. Soil removal was facilitated by the construction of a shoring box designed by a structural engineer, to accommodate safe mechanical removal within the defined area of impact, adjacent to the western exterior wall of the house. Soil removal operations were performed over several days in August and September, 2017. Beginning on August 8, 2017, grossly-impacted material was removed from the release area by a vactor and contained in a vactor can for later transport to Aggregate Industries South Dennis asphalt batching plant. Clean overburden material was then removed from the surrounding area and stockpiled at the site, in order to access significantly impacted soils at greater depths. On August loth the shoring contractor began constructing the shoring box to advance the excavation to the proposed depth of 15' below grade. On August 22°d soil samples were collected from representative sidewalls and bottom of hole areas in Zone A, for laboratory analysis. Field screening results reported elevated PID readings (<100 ppmv) from the northern and southern I DECEMBER 14,2017 ENNES—2 GENERAL PATTON DR.HYANNISBEAI7-11006 PAGE 12 OF 28 IRAC-PSS,RTN 4-26544 sidewalls, as well as the northern and southern bottom of hole samples. Based on the field screening results observed, it was apparent that there was residual impact in these locations. err = -• � �4 - � , ,-`�. Photo 3:View of excavation adjacent to dwelling(Zone A). Results reported all concentrations of fractional EPH/PAHs and VPH/BTEX as.Non-Detect or as below the most stringent S-1/GW-1 Method 1 Standards, with the exception of the northern and southern sidewalls. The southern sidewall (SW-S: 3-15') reported minor concentrations of 2- Methy1napthalene above the S-1/GW-1 Standard. The northern sidewall (SW-N: 6-15') reported several concentrations of EPH/VPH and target analytes above the S-1/GW-1 and GW-3 Method 1 Standards. Based on these results it was apparent that additional soils needed to be removed along the northern sidewall. Results are summarized relative to Method 1 below in Table 4.

The shoring . contractor suggested using 4" PVC pipes to advance the excavation laterally. The structural engineer indicated that he would revise the shoring plan to facilitate the additional work. Two Vapor Pins© were also installed at the Site on September 5th, for later soil vapor sampling by APH analysis, in consideration of vapor intrusion. The first soil vapor point (SVP-1) was installed in the full basement of the subject dwelling, in the work shop, located in the northern portion of the basement. The second soil vapor point (SVP-2) was installed through the concrete slab, in a utility closet kitchen, in the central portion of the dwelling. Groundwater sampling was also conducted during the September 5th site visit. Monitoring wells MW-1 and MW-2 had been destroyed during soil removal activities. Monitoring wells MW- 3, MW-4 and MW-5 were sampled for EPH/PAH and VPH/BTEX analyses. Results of groundwater samples were received on September 13, 2017. The results reported low concentrations of C 11-C22 Aromatics in down-gradient monitoring well MW-4. All other concentrations of fractional EPH/VPH and target analytes were reported as Non-Detect.

This was accomplished by driving PVC piping into the sidewall of the excavation and using the vactor-truck to remove the soil. Soil samples were collected from the eastern and southern sidewalls of the extended Zone B (Zone. B X1) and were submitted for laboratory analysis for EPH and VPH with target analytes. BEA personnel also performed indoor air screening on September 12th. PID readings were reported as Non-Detect on the first floor and as 0.2 ppmv in the basement, with a solvent odor noted. When asked about the solvent odor,the client indicated that he had used solvent to clean some paint brushes in the work room in the basement. The soil vapor points were also screened with a PID. The results of PID screening reported an organic vapor reading of 80+ ppmv at SVP-1 in the basement and a PID reading of 2.4 ppmv at SVP-2 on the first floor. Soil removal continued September 14-15 by extending both Zone A and Zone B to the north, beneath the bulkhead stairs and basement. Soil samples were collected from these locations extended off the existing excavation(Zone A X1 and Zone B X1) and were submitted for laboratory DECEMBER 14,2017 ENNES-2 GENERAL PATTON DR.HYANNISBEAI7-11006 PAGE 16 OF 28 IRAC-PSS,RTN 4-26544 analysis for EPH and VPH with target analytes. In addition, soil samples collected on September 11-12 from the bottom of hole areas in Zone B X1, were also submitted, as BEA was convinced that no additional soil removal would be performed. Results of soil analysis were reported on September 19 and 26, respectively. The soil sampling results, from the eastern and southern sidewalls of Zone.B X1 reported all concentrations of fractional EPH and VPH and target analytes as Non-Detect, or as below the most stringent S- 1/GW-1 Standards. These samples were all collected from below the 4' frost wall, beneath the portion of the dwelling with slab-on-grade construction.

The infiltration system, constructed of 4" perforated PVC set in washed stone aggregate backfill, was then installed to provide flexibility for the potential addition of RegenOx Part B, which would have then activated the chemical oxidation process, later deemed unnecessary. The infiltration system also serves as a passive vent and preferential pathway for the evacuation of any residual organic vapors, as well as serving to increase air flow to the subsurface to enhance microbial activity and natural attenuation . of any residual soil impacts. The vent pipe will also facilitate PID screening of soil vapor in the area of soil removal, in consideration of potential vapor entry. In accordance with the provisions of 310 CMR 40.0926(3)(b), an estimated Exposure Point Concentration (EPC) was considered as the simple mean concentration of contiguous discrete exposure points, wherein more than 75% of the data met the applicable Method 1 standards. The resulting EPCs for the analytes reported above (C5-C8 Aliphatics, C9-C10 Aromatics, 2- methlynaphthalene, C l l-C22 Aromatics and C9-C 18 Aliphatics) were significantly less than the most restrictive S-1/GW-1, Method 1 standards. . Wherein a condition of No Significant Risk was apparent, Part B of the Regenesis © RegenOx in-situ chemical oxidant remedial additive was not applied at the Site. The excavation was backfilled on September 19, 2017. During backfilling of the excavation with flowable fill the foreman noted that the level of fill was no longer rising in the excavation and g g then suddenly began to drop. Suspecting the fill had somehow entered the basement; the foreman I . DECEMBER 14,2017 ENNES-2 GENERAL PATTON DR.HYANNISBEAI7-11006 PAGE 18 OF 28 IRAC-PSS,RTN 4-26544 entered the basement and confirmed that the flowable fill had, in fact entered the basement, resulting in approximately 18" of flowable fill entering the workshop, storage area and hallway in the basement. The contractor worked to remove the flowable fill from the basement with 5-gallon buckets and later a vactor-truck. A subsequent inspection of the basement area indicated a thorough clean-up was performed by the contractor. BEA returned to the site on October 4, 2017 to collect soil vapor samples from the previously installed Vapor Pins© for APH analysis. Both soil vapor probes were screened with a PID prior to sampling. SVP-1 reported a PID reading of 13.5 ppmv after 10 mins of screening with the PID, SVP-2 reported a PID reading of 0.1 ppmv after 10 mins. The samples were subsequently collected using a 2.7 liter summa canister with a 200 ml/min flow controller. The samples were sent to Alpha Analytical Laboratories for"APH testing. Results of the soil vapor samples were reported on October 11, 2017. The results reported concentrations of C9-C12 Aliphatics and C9-C10 Aromatics in soil vapor point SVP-1 (basement) which significantly exceeded the Residential Sub-Slab Soil Gas Screening Values per the.Mass DEP Vapor Intrusion Guidance Document (Policy #WSC-16-435).

As such, BEA prepared to conduct indoor air sampling at the site. Items containing VOCs were removed from the dwelling and were stored in an outdoor shed. Indoor air sampling was performed on October 24, 2017. Three 6.0-liter summa canisters with 24-hour flow controllers were used to collect indoor air samples from different locations throughout the house. The sampling.locations included the master bedroom, the family room at the top of the basement stairs and the basement of the subject dwelling. It should be noted that the basement is not a habitable space. But overlies a portion of the area of excavation as does the open kitchen leading to the family room. The samples were collected with the windows closed and the heating system running in order to simulate worst case conditions. During the October 24, 2015 site visit, groundwater DECEMBER 14,2017 ENNES—2 GENERAL PATTON DR.HYANNISBEAI7-11006 PAGE 19 OF 28 IRAC-PSS,RTN 4-26544 monitoring was also performed. Monitoring wells MW-3, MW-4 and MW-5 were purged and sampled for EPH/PAHs and VPH/BTEX. The samples were picked up on October.25, 2017 and sent to Alpha Analytical to be analyzed for APH analysis. Results of indoor air sampling were received October 31, 2017. The results reported no concentrations of APH or target analytes above the Residential Threshold Values Criteria, per the MassDEP Vapor Intrusion Guidance (Policy#WSC-16-435).

The results reported all concentrations of EPH/PAHs and VPH/BTEX as Non-Detect, wherein the reporting limits of the analyses were less than or equal to the most stringent GW-1, Method 1 Risk Characterization Standards. RISK CHARACTERIZATION/IMMINENT HAZARDS [Refer to Appendix D] As presented, the S-1, S-2 and S-3 (GW-3) soil categories are applicable in consideration of Method 1 Risk Characterization, as consistent with the provisions of 310 CMR 40.0933. These standards were developed to evaluate potential ingestion, particulate inhalation, dermal contact and in consideration of potential leaching of contaminants to groundwater as based on accessibility, frequency and intensity of use of the soils. Likewise, groundwater is divided into the GW-1 (ingestion), GW-2 (inhalation) and GW-3 (dermal contact and environmental impacts). For the purposes of risk characterization, the strictest S-1 (GW-1/GW-3), Method 1 Risk Characterization standards are considered, in review of exposures related to foreseeable future uses and activities at the Site. Soil Subsequent to the completion of contaminated soil removal, laboratory analysis of end-point soil samples reported all EPH/VPH and target analyte concentrations along the extent of excavation as less than the applicable and strictest S-1 (GW-1/GW-3), Method 1 Risk Characterization DECEMBER 14,2017 ENNES-2 GENERAL PATTON DR.HYANNISBEAI7-11006 PAGE 20 OF 28 IRAC-PSS,RTN 4-26544 Standards, with the exception of three exposure point locations: Zone A SW-S: 3-15' reported 2- Methy1naphthalene exceeding the S-1, S-2 and S-3/GW-1 criteria; Zone B BOH(N):15-16' reported C5-C8 Aliphatics, C9-C10 Aromatics, 2-Methylnapthtalene; and C9-C18 Aliphatics, above various Method 1 Standards. Zone B BOH(S): 15-16' reported C5-C8 Aliphatics, C9-C10 Aromatics, 2- Methytnapthtalene, Cl l-C22 Aromatics and C9-C18 Aliphatics above both the S-1/GW- and the S- 1/GW-3 Method 1 Standards. Based on the identified analytes reported above the applicable Method 1 Risk Characterization Standards, Exposure Point Concentrations (EPC) were calculated pursuant to 310 CMR 40..0926(3)(b), to evaluate Significant Risk. Based on contiguous soils, a simple mean value was calculated wherein 75% of the data points used in the averaging process were equal to or less than the applicable S-1/GW-1 Method 1 Standards. The EPC values calculated for the analytes identified were less than the corresponding Method 1 Standards. As such, laboratory analytical data for end-point soil conditions supports a finding of No Significant Risk for ingestion, particulate inhalation and dermal contact exposures or potential leaching of contaminants to groundwater and environmental impacts, as defined in the MCP. Table 11 is a summary of the end-point soil samples with the computed EPC, and is included for reference in Appendix D. As a conservative measure in consideration of potential exposure risk, the specific area of greatest residual soil impact was treated as a potential hotspot. The highest reported EPH/VPH and target analyte concentrations for the Zone B BOH(S): 15-16' sample, as isolated by depth and under a permanent structure, were input into the Method 3 Resident- Soil Short Form, as a "worst case" discrete exposure.

Given this information, both HIs are reported as less than 1, the ELCR reported as less than 1/100,000 (10-5), and based on the laboratory analytical EPC under Method 1, and discrete exposure of potential "hot spot" under Method 3, No Imminent or Substantial Hazards presently exist, and a condition of No Significant Risk is supported under the DECEMBER 14,2017 ENNES-2 GENERAL PATTON DR.HYANNIS/BEA17-11006 PAGE 21 OF 28 IRAC-PSS,RTN 4-26544 Method 1 and Method 3 EPC evaluations, relative to residual impacts below the basement floor of the subject dwelling. As such, soil removal has effectively mitigated the contaminant source and now represents a condition of No Significant Risk based on a preponderance of evidence and evaluation of laboratory analytical under Method 1, as supported Method 3 considerations of discrete data sets. Groundwater Based on the PDWSA designation and proximity to groundwater, the GW-1 and GW-3 groundwater categories are considered applicable in consideration of Method 1 - Risk Characterization standards, as consistent with the provisions of 310 CMR 40.0932. These standards were developed to evaluate potential ingestion (GW-1), inhalation and environmental/dermal contact(GW-3) exposures. However, based on the location of the subject property as one-half mile down-gradient of the Town of Barnstable Wastewater Treatment Facility, it seems unlikely that the area would be developed as a drinking water source. As such, BEA believes that the exposure risk from ingestion is overstated. In addition, MA DEP BWSC GIS mapping shows a Non-Potential Drinking Water Source Area (NPDWSA) across Bearses Way 200 feet northeast of the subject property. The NPDWSA continues southeast and southwest of the subject property, surrounding the Site on three sides. The initial sampling of monitoring well MW-1 in March 2017 indicated low concentrations of PAHs below the GW-1 Method 1 Standards. Monitoring wells MW-2 and MW-3 were installed in May 2017. Monitoring Well MW-3 reported EPH/PAHs and VPH/BTEX as Non-Detect. Upon sampling MW-2, installed within the release area, concentrations of VPH fractional C9-C10 Aromatics, EPH fractional C 11-C22 Aromatics and 2-Methylnaphthalene were reported marginally above the GW-1 Standards. Monitoring wells MW-4 and MW-5 were installed and sampled in June 2017, with results reported as Non-Detect. During soil removal activities, monitoring wells MW-1 and MW-2 were destroyed. Monitoring wells MW-3, MW-4 and MW-5 were sampled again in September 2017. Results reported low concentrations of EPH fractional Cll-C22 below the GW-1 Standards in MW-4, with MW-3 and MW-5 reporting concentrations of petroleum hydrocarbons and target analytes as Non-Detect. Monitoring wells MW-3, MW-4 and MW-5 were sampled again in October 2017, with all wells reporting all concentrations of EPH/PAHs and VPH/BTEX as Non-Detect. As such, based on the three .rounds of groundwater monitoring conducted in down-gradient wells through the projected solute pathway and time of travel, support and qualify a fmding of No Significant Risk associated with potential leaching and groundwater impacts, following soil removal specific to both the GW-1 and GW-3, Method 1 criteria. Indoor Air Subsequent to the removal of impacted soils, analytical results from the end-point soil samples reported residual concentrations of fractional EPH and VPH, and target PAH/BTEX analytes above the S-1/GW-1 Method 1 Standards. The samples reporting residual impact were collected from sidewall and bottom of hole samples located within the setbacks framed in 310 CMR 40.0942(l)(d), indicating potential vapor entry into the building. As such in October 2017, soil vapor samples were collected from two locations beneath the dwelling as corresponding to the endpoint sampling locations. Soil vapor point#1 (SVP-1) was installed within the full basement, in the small workshop in the northern portion of the basement. Soil vapor point 42 (SVP-2) was installed through the concrete slab on the first floor, within the utility closet in the kitchen. Soil i DECEMBER 14,2017 ENNES-2 GENERAL PATTON DR.HYANNISBEAI7-11006 PAGE 22 OF 28 IRAC-PSS,RTN 4-26544 vapor testing for APH reported concentrations of fractional C9-C12 Aliphatics and C9-C10 Aromatics above the Residential Sub-Slab Soil Gas Screening Values (RSSGV) in SVP-l. Concentrations of APH in SVP-2 were reported below the RSSGV. Based on these results it was apparent that additional lines of evidence were needed to rule out potential vapor intrusion. BEA subsequently performed indoor air testing within the dwelling. Three indoor air samples were collected using 6-liter summa canisters fitted with 24-hour flow controllers. The samples were collected from the basement, the first-floor master bedroom and the first floor family room at the top of the basement stairway. Results of the indoor air samples reported all concentrations of APH and target analytes as below the Residential Threshold Values specified within the Mass DEP Vapor Intrusion Guidance. Based on the results of the indoor air testing, there is no vapor intrusion pathway and as such No Significant Risk associated with petroleum vapor entry and related inhalation exposures following soil removal. DATA USABILITY ASSESSMENT & REPRESENTATIVENESS EVALUATION The following presents a discussion of the Site information used to support the PSS as . required by 310 CMR 40.1056(2) (k) and incorporating the guidance provided in MA. DEP Policy WSC-07-350. It provides an evaluation and demonstration of the adequacy of the spatial and temporal data sets used to support the PSS and makes conclusions on the accuracy, precision and sensitivity of the data used as consistent with the internal QA/QC Policies of BEA [Refer to Appendix F]. Conceptual Site Model Up to 250 gallons of fuel oil was released from a corroded AST adjacent to the exterior wall of the dwelling on February 25, 2017. The fuel oil was released to the concrete pad beneath the tank and then ran over the pad and infiltrated to subsurface soils. The release was stopped when the oil company used a magnetic patch to stop the leak, however, by that time the tank was already empty. Absorbents were applied to recover puddled fuel and an environmental contractor used plastic to cover the area. An investigation by the insurer's consultant (MW-1) initially did not identify groundwater impact above GW-1 Standards. The subsequent investigation by BEA did identify groundwater impact above the GW-1 Standards in a monitoring well (MW-2) installed within the release area. An initial proposal of a 12' x 6' area of excavation to 10-15' deep was later revised to a 10' x 16' area to 15' deep, with the benefit of additional data. Mechanical soil removal was performed, as the preferred remedial strategy, with contaminated soils transported directly to a licensed asphalt batching facility for recycling. Over the course of several days, approximately 60 yards (89.9 tons) were removed from an approximate 16' x 18' irregular-shaped area to 15-16' below grade. Laboratory results of end-point testing reported fractional EPH and VPH, as well as 2-Methylnaphthalene above the S-1/GW-1 Method 1 Standard in three samples. The balance of the analytical results reported all concentrations of petroleum hydrocarbons as Non-Detect or as below the S-1/GW-1 Standards. An exposure point concentration was developed under Method 1 Risk Characterization which indicated that No Significant Risk was apparent with respect to residually impacted soils. During groundwater sampling, concentrations of fractional EPH, VPH and 2- Methylnaphthalene were reported above the GW-1 Risk Characterization Standards once in May DECEMBER 14,2017 ENNES-2 GENERAL PATTON DR.HYANNISBEAI7-11006 PAGE 23 OF 28 IRAC-PSS,RTN 4-26544 2017. Subsequent groundwater monitoring of downgradient wells has reported all EPH/PAHs and VPH/BTEX as Non-Detect or below the most stringent GW-1 Standards. Indoor air screening has reported background conditions and no petroleum odors were observed inside the dwelling. However, based on the residual concentrations of VOCs in soil, soil vapor sampling was conducted. Results of soil vapor sampling reported concentrations of petroleum hydrocarbons above the RSSGV, in the soil vapor point installed within the basement. This necessitated indoor air sampling to demonstrate vapor intrusion was not a concern. Indoor air sampling was subsequently performed at three locations within the dwelling; the basement, the master bedroom and the family room. The results of the indoor air sampling reported all concentrations of APH and target analytes below the RTVs specified within the Mass DEP Vapor Intrusion Guidance document at all locations including the unfinished basement area overlying the area of soil removal. Based on the results of indoor air sampling, it was apparent that vapor intrusion pathways are incomplete and that vapor entry is not a concern relative to indoor air quality. As such, based on the results of soil, groundwater and indoor air testing, a Condition of No Significant Risk is opined, in support of a Permanent Solution without conditions. Field Screening PID screening and field observations were used to qualify significant impact in soils and to make informed, dynamic decisions in the field in advance of submitting samples for MA Certified analyses. In some cases, Dexsil PetroFlag testing was conducted to qualify TPH concentrations in the field. Samples with higher levels of odor or PID readings were assumed to be more contaminated than those samples with lower levels. Comparison of visual observations, PID screening results and laboratory analytical data indicates that the field screening data correlates well with the analytical data. Sampling Locations The removal of impacted soils was performed based on field PID/Dexsil PetroFlag screening and visual observations, as work progressed from contaminated soil to clean soil. PID/Dexsil PetroFlag screening was used to qualify the horizontal and vertical extent of contaminated soil, in support of excavation and loading activities. TPH; EPH and VPH laboratory analysis were used to evaluate the impacted soils based on the nature of the contaminant being fuel oil. Soil samples were collected for analyses from the extent of soil removal from representative bottom-of-hole and sidewall areas as critical samples. All end-point soil samples were preserved for EPH/PAH and VPH/BTEX analysis. The samples were placed in appropriately preserved laboratory containers in the field and stored on ice in a cooler, pending shipment to the laboratory under a properly executed chain-of-custody. Monitoring well installation was originally performed within the release area to establish significant impact to groundwater. Additional groundwater monitoring wells were subsequently installed in definitively down-gradient locations from the release area. The locations of the monitoring wells were based on regional groundwater flow patterns and local knowledge of flow direction. The monitoring wells were installed across the groundwater interface, as representative of groundwater impacts within the solute pathway, and in proximity to the source area. DECEMBER 14,2017 ENNES-2 GENERAL PATTON DR.HYANNISBEAI7-11006 PAGE 24 OF 28 IRAC-PSS,RTN 4-26544 Field duplicates or trip blanks for soil sampling were not collected nor considered necessary because the Disposal Site was small, the removal operations had produced clean conditions along the vast majority of exposure points, QA/QC protocols were employed and documented with Method Blanks and Spikes performed by the laboratory and evaluated under CAM protocols for Presumptive Certainty. Temporal Data Soil samples were collected subsequent to the excavation of contaminated material. Due to soil removal as the primary remedial strategy, temporal data for soils was not applicable in consideration of final exposure risks, and laboratory analysis of confirmatory end-point samples was relied on for risk characterization. In the case of groundwater, monitoring well MW-2, installed within the release area, reported elevated concentrations of fractional EPH, VPH and 2-Methylnaphthalene above the applicable GW-1 Method 1 Risk Characterization standards during the first sampling event in May 2017. Monitoring wells MW-3, MW-4 and MW-5 were installed in June 2017, with monitoring wells MW-3 and MW-4 directly down-gradient of the release area. Monitoring wells MW-1 and MW-2 were subsequently destroyed during soil removal activities. Monitoring well MW4 reported low concentrations (155 ug/L) of C l l-C22 Aromatics, below GW-1 Standards, during the September groundwater sampling event. Monitoring wells MW-3 and MW-4 most recently reported all concentrations of EPH/VPH and target analytes as Non-Detect during the October 2017 sampling event. Based on the concentrations of EPH/VPH reported as below all applicable standards, representative groundwater quality has been documented within the release area with temporal information through two quarterly sampling events. Indoor air was sampled in October 2017, with the occupants relocated temporarily. The samples were collected under conservative conditions, with the windows shut and the heating systems running. Results of indoor air sampling reported all concentrations of APH and target analytes as below the Residential TLVs, indicating no significant impact to indoor air as defined within the current vapor intrusion policy. In addition, no PID readings related to petroleum impact and no petroleum odors have been observed within the dwelling. As such, a condition of No Significant Risk exists at the site, relative to potential vapor intrusion and inhalation hazards for residential use, wherein temporal data is critical to exposure considerations and risk characterization. As based on the consistency of the spatial testing in the living area (master bedroom and family room), and analytical results in the unfinished basement (basement) above the area of excavation, the data set was considered representative of the vapor intrusion pathway; the need to again relocate the tenants with medical conditions in order to carry the project through Tier Classification was deemed unwarranted and unnecessary. Field Completeness The analytical data set is complete. Data from the sidewall and bottom-of-hole areas was obtained as representing the extent of contaminated soil removal. Groundwater data represents groundwater quality within and down-gradient of the area of release as evaluated under projected solute modeling and fate considerations. Soil Vapor and Indoor Air data was collected at several representative points within the dwelling and in the basement area. The complete data set supports DECEMBER 14,2017 ENNES-2 GENERAL PATTON DR.HYANNISBEAI7-11006 PAGE 25 OF 28 IRAC-PSS,RTN 4-26544 the PSS wherein all QA/QC thresholds and Presumptive Certainty requirements were met or technically justified. Data Inconsistency No inconsistent data was identified. Visual observations, odors and field screening results were generally well-correlated. No inconsistency was identified between the field screening of the balance of end-point soil samples and their respective laboratory analyses. Data Not Used The complete analytical data set associated with confirmatory end-point soil samples was considered. Data Usability The analytical data used was validated and justified as representative of environmental conditions. Soil samples from the extent of excavation were collected as representing discrete exposures in representative soil categories as a measure of frequency and intensity of use. The methods utilized (PID soil screening, Dexsil PetroFlag testing, TPH/EPH/VPH) all respond to the contaminant of concern identified and are appropriate for a release of#2 fuel oil. Based on the Representativeness Evaluation under MA DEP Policy WSC-07-350 (REDUA), the analytical data quality of all end-point soil samples relied on, in support of the PSS, has been reviewed. The analytical data provided in support of this PSS has met the method quality control requirements and performance standards for "Presumptive Certainty" as described in CAM VII A, Section 2.0 (a), (b), (c), and (d) or have been evaluated as comparable.to CAM requirements. The validity and defensibility of the analytical data used to support the findings of the PSS for this Site with respect to accuracy, precision and completeness pursuant to 310 CMR 40.1056(2)(k) have therefore been satisfied [Refer to QA/QC—Appendix F]. In the lab analysis for the groundwater samples collected on May 4, 2017 (Work Order #1705-09518) the CAM narrative reported an affirmative response for Questions A through F, as well as H and I, with a negative response for Question G. The negative response for Question G was issued wherein the limited 4 PAH list was requested during EPH analysis. These target analytes were appropriate for a virgin fuel oil release at a residential property with no commercial or industrial history. These target analytes are also specified to be used per the MA DEP EPH/VPH Guidance document. As such these results meet presumptive certainty for use as critical data. In the lab analysis for the first round of end-point samples collected on August 22, 2017 (Lab# L1729649) the CAM narrative reported an affirmative response for Questions A through F, 4 as well as I, with a negative response for Questions G and H. The negative response for Question G was issued wherein CAM reporting limits were not met due to elevated reporting limits which were attributed to high concentrations being reported. Regardless, the accuracy and precision of this data meets Presumptive Certainty under the REDUA evaluation for use in calculating an EPC against Method 1 Standards.. The negative response for H was in reference to surrogate recoveries outside the acceptance criteria and associated high and low bias. Again, the accuracy and precision of this data meets Presumptive Certainty under the REDUA evaluation for use in calculating an EPC DECEMBER 14,2017 ENNES-2 GENERAL PATTON DR.HYANNISBEAI7-11006 PAGE 26 OF 28 IRAC-PSS,RTN 4-26544 against Method 1 Standards. In the lab analysis for the second round of end-point samples collected on August 28 2017 Y p p g (Lab# L1730356) the CAM narrative reported an affirmative response for Questions A through F, as well as I, with a negative response for Questions G and H. The negative response for Question G was issued wherein CAM reporting limits were not met due to elevated reporting limits which were attributed to high concentrations and co-elution with obvious interferences being reported. Regardless, the accuracy and precision of this data meets Presumptive Certainty under the REDUA evaluation for use in calculating an EPC against Method 1 Standards. The negative response for H was in reference to surrogate recoveries outside the acceptance criteria and associated high and low bias. Again,the accuracy and precision of this data meets Presumptive Certainty under the REDUA evaluation for use in calculating an EPC against Method 1 Standards. In the lab analysis for the groundwater samples collected on September 5, 2017.(Lab# L1731255), the CAM narrative reported an affirmative response for Questions A through I, with the exception of Question H, which reported a negative response. The negative response was given because of multiple LCS/LCSD recoveries of non-target analytes and RPD limits of target analytes greater than 25%. This data is considered as non-directional bias as a measure of precision. Regardless, all analytes were reported as Non-Detect wherein target analytes were reported as less than the strictest GW-1 Method 1 Standards. As such these results meet presumptive certainty for use as critical data. In the lab analysis for the third round of end-point samples collected on September 12, 2017 (Lab# L1732161) the CAM narrative reported an affirmative response for Questions A through I, with the exception of Question H, which reported a negative response. The negative response for Question H was issued wherein the surrogate recoveries were outside the acceptance criteria for two analytes. This introduces potential high bias for VPH related recoveries. Regardless, all analytes were reported as Non-Detect wherein target analytes were reported as less than the strictest GW-1 Method 1 Standards. As such these results meet presumptive.certainty for use as critical data. In the lab analysis for the fourth round of end-point samples collected on September 15, 2017 (Lab# L1733079) the CAM narrative reported an affirmative response for Questions A through I, with the exception of Question H, which reported a negative response. The negative response for Question H was issued wherein the surrogate recoveries were outside the acceptance criteria for two analytes. This introduces potential high bias for VPH related recoveries. In addition, multiple LCS/LCSD recoveries were reported as greater than 25%. In each case, all analytes were reported as Non-Detect wherein target analytes were reported as less than the strictest GW-1 Method 1 Standards. As such these results meet presumptive certainty for use as critical data. In the lab analysis for the indoor air samples collected on October 25, 2017 (Lab# L1738816), the CAM narrative reported an affirmative response for Questions A through F, as well as I, with a negative response for Questions G and H. The negative response for Question G was issued wherein one or more of the target analytes did not achieve the requested CAM reporting limits. Under APH analysis Naphthalene had reporting limits above the RTVs, however under VOC analysis by SIM, Naphthalene was reported below the RTVs. In addition, C9-C10 Aromatics had reporting limits at the RTV. In each case, these results meet presumptive certainty for use as critical data. DECEMBER 14,2017 ENNES-2 GENERAL PATTON DR.HYANNISBEAI7-11006 PAGE 27 OF 28 IRAC-PSS,RTN 4-26544 In the review of all the critical laboratory analytical soil data, the noted QA/QC issues associated with these analyses did not significantly affect risk analysis and met Presumptive Certainty under the REDUA evaluation for the intended use of critical data evaluation of potential exposures,relative to Significant Risk as defined under the MCP. BACKGROUND FEASIBILITY EVALUATION A review.of cost and feasibility to meet background conditions through additional soil removal was considered as part of this IRA, in accordance with the provisions of 310 CMR 40.1020. Fractional EPH and VPH compounds and the PAH 2-Methylnaphthalene, were detected in three end-point samples above the most stringent S-1/GW-1 Method 1 Risk Characterization. Standard. The remaining samples have reported all EPH/VPH and target analyte concentrations in soil as Non-Detect or less than the most restrictive S-1 (GW-1/GW-3), Method 1 Risk Characterization standards. An EPC, calculated in compliance with 310 CMR 40.0926, has demonstrated a condition of No Significant Risk with respect to soils at the Site. In addition, an infiltration system continues to provide passive bioventing to the subsurface towards background conditions,though the IRAC/PSS is not reliant on any passive treatment or degradation of residuals. As such, current environmental conditions associated with residual low-level petroleum concentrations in soil as non-persistent, naturally degrading compounds meet the "Conditions of Categorical Infeasibility" established in Section 9.3.2 of the MA DEP policy "Conducting Feasibility Evaluations Under the MCP" (WSC-04-160), as specifically pertaining to Section 9.3.2.3, "Remediation of Degradable (Non-persistent) Contaminants". GARDENING BEST MANAGEMENT PRACTICES [Refer to Appendix E] Laboratory analyses, of end-point soil samples, in conjunction with a calculated EPC, currently meet the applicable and strictest S-I (GW-1/GW-3), Method 1 Risk Characterization standards and as such, laboratory analytical results support a Permanent Solution without conditions, and Gardening Best Management Practices (BMPs) are not required. Notwithstanding, Method 1 does not currently consider ingestion exposure scenario associated with the vegetative uptake for exposure. As such, regulations compel language to identify this potential exposure when Method 1 relied upon. Thus,property owner and resident(s) of 2 General Patton Dr. in Hyannis, MA are hereby advised to consider implementing BMPs to further reduce potential exposure to material in the soils for the raising and consumption of homegrown produce used for human consumption. Implementing BMPs such as those referenced in Appendix E will allow safer gardening in a wider range of site conditions. Not every BMP is necessary for every single site, but a combination of BMPs site will help reduce the potential for additional exposure risks'at urbanized site_ s and or areas of historic fill [Refer to Appendix E for reference to appropriate Gardening BMPs]. Neither of these conditions appears to apply to the subject Site. CONCLUSIONS/LIMITATIONS Based on the expedited removal of significant soil impacts, with subsequent laboratory analytical results and calculated Exposure Point Concentrations reporting concentrations of petroleum hydrocarbons below the applicable standards, a condition of"No Significant Risk" exists DECEMBER 14,2017 ENNES-2 GENERAL PATTON DR.HYANNIS/BEA17-11006 PAGE 28 OF 28 IRAC-PSS,RTN 4-26544 for activities and uses of the Site. No significant impact to the environment, or risk to human receptors, was qualified by physical testing of the end-point soil samples collected. As such, a Permanent Solution Statement (PSS) without Conditions has been achieved, is applicable to support completion of the IRA (IRAQ and closure of the project, in accordance with the provisions of 310 CMR 40.1036 and 40.1056.

(BEA) has prepared the following Immediate Response Action Status (IRAS) Report and Supporting Documentation, as a summary of remedial response actions and the environmental assessment activities conducted in the past 60 days since the IRA Plan filing, on June 12, 2017. This information is being used to evaluate potential exposure risk to identified human and environmental receptors, following the sudden release of a reported 250 gallons of No. 2 heating fuel from an exterior above ground storage tank(AST), located adjacent to the dwelling. Over the reporting period, environmental assessment and monitoring activities have included the performance of test borings and the installation of additional groundwater monitoring wells, with the collection and laboratory analysis of soil and groundwater samples. These additional assessment activities were performed to more accurately define the extent and magnitude of soil and groundwater impact. Results of soil analysis have confirmed the proposed area of excavation in a 16' x 10' area to approximately 15' deep. Results of groundwater analysis indicate no impact to down-gradient monitoring wells, confirming localized impact only, in the immediate area of release. In addition, proposals were requested from qualified contractors to perform soil removal activities in the release area, using a shoring plan drafted by a structural engineer. Frank Corp. of New Bedford, MA was chosen as the contractor, and work is scheduled to begin the week of August 7, 2017. Subsequent to soil removal activities, soil samples will be collected at the extent of the excavation for extractable petroleum hydrocarbons (EPH) with polycyclic aromatic hydrocarbons (PAHs) and volatile petroleum hydrocarbons (VPH) with target benzene, toluene, ethylbenzene 1 EMERGENCY SPILL RESPONSE A WASTE SITE CLEANUP 6 SITE ASSESSMENT 6 PERMITTING 6 SEPTIC DESIGN&INSPECTION WATER SUPPLY DEVELOPMENT,OPERATION&MAINTENANCE & WASTEWATER TREATMENT,OPERATION&MAINTENANCE AUGUST 2,2017 ENNES:2 GENERAL PATTON DR.BEA17-11006 PAGE 2 OF 12 IMMEDIATE RESPONSE ACTION STATUS I,RTN 4-26544 and xylenes (BTEX) compounds. Prior to backfilling, 400 lbs. of Regenesis RegenOx® part A will be mixed into bottom of hole soils, as a contingency to treat any residual petroleum impact. A remedial additive infiltration system will then be installed within the excavation. The infiltration system will be constructed of 4" perforated PVC piping set in double washed stone aggregate. The system will be installed for the application of 240 lbs. of RegenOx® part B, if laboratory analytical results indicate additional treatment is required. Future environmental monitoring activities proposed includes two quarterly rounds of groundwater sampling, to monitor for the migration of any dissolved phase petroleum impact to down-gradient monitoring wells MW-3 and MW-4. In addition, indoor air within the living space and the infiltration system vent will be screened with a photoionization detector (PID) for organic vapors or odors. The indoor air and soil vapor screening will serve as part of the multiple lines of evidence to evaluate potential vapor intrusion and inhalation exposure risks. The results of environmental response actions proposed, will dictate the need for any additional remedial measures to be represented in future IRA Status reports, filed within six months of this IRA Status Report. Remedial response activities performed, and potentially to follow, are intended to mitigate any Critical Exposure Pathways and Significant Risk to identified human and environmental receptors, in support of a Permanent Solution Statement (PSS). It is the objective of this IRA to offer a PSS in advance of the one-year Tier Classification deadline, based on the technical rational and scientific justification from the field testing and analytical results presented herein. This work has and will continue to proceed 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. RESPONSE ACTIONS/PRELIMINARY ASSESSMENT On February 25, 2017 the homeowner found the 275-gallon fuel oil AST actively leaking. Subsequent to release discovery the Hyannis Fire Department responded and applied granular absorbents to the concrete pad beneath the tank. The absorbents were later collected and taken off-site for disposal by emergency response contractor NRC/ENPRO. EnviroTrac, Ltd. was later contracted to investigate the release by the homeowner's Insurer (Liberty Mutual). On March 22, 2017, EnviroTrac personnel performed a single test boring approximately 4' outside the area of soil staining and installed a single groundwater monitoring well. Continuous soil sampling and PID screening was conducted from the surface to the groundwater with a maximum PID reading of 160 ppmv reported in the 8-10' interval and 54.3 ppmv at the groundwater interface at 23'below grade. A single soil sample (MW-1 24')was submitted to SGS Accutest Lab for EPH/4PAHs and VPH/BTEX analysis. Groundwater from AUGUST 2,2017 ENNES:2 GENERAL PATTON DR.BEA17-11006 PAGE 3 OF 12 IMMEDIATE RESPONSE ACTION STATUS I,RTN 4-26544 monitoring well (MW-1) was also collected and submitted to Accutest for EPH/4PAHs and VPH/BTEX analysis. dj ;yt t,A Photo 1: View of subject AST with monitoring well MW-1 in foreground. Results of soil analysis reported low concentrations of fractional EPH and VPH below the most stringent S-1/GW-1 Method 1 Risk Characterization Standards. Results of groundwater analysis reported low concentrations of target PAHs below the GW-1 Method 1 Risk Characterization Standards. Upon review of the data, BEA responded directly to Liberty Mutual regarding the testing performed. BEA believed that the testing was flawed, based on the location of the test boring and monitoring well (MW-1) installed outside of the release area and in a location up-gradient of regional groundwater flow. In addition, it was noted that the only soil sample submitted (MW-1 24') was collected from below the groundwater interface, and did not correspond with the elevated PID readings observed. BEA, acting outside the role of LSP, believed these results clearly indicated soil impact to the groundwater interface impacting groundwater. However, the sample selection for soil and groundwater did not consider the spatial locations of soil impacts as outside the area of soil staining, or the solute fate of groundwater, and did not give a clear picture of environmental conditions as the basis of Insurer's denial of Coverage. On behalf of the property owners, BEA then requested they reconsider insurance coverage based on the flawed assessment performed by their consultant. The Insurer declined to reconsider coverage and took the position that no coverage would be afforded to the Insured unless groundwater impact was documented above GW-1 Standards. AUGUST 2,2017 ENNES:2 GENERAL PATTON DR.BEA17-11006 PAGE 4 OF 12 IMMEDIATE RESPONSE ACTION STATUS I,RTN 4-26544 Upon consultation with the property owner, additional assessment activities were scheduled to qualify previous testing results. BEA arranged for the AST to be removed for clear access to the area of release for subsequent testing, and on April 28, 2017, BEA personnel performed soil borings and monitoring well installation activities at the property. Two soil borings were performed at the site to determine the general nature and extent of impacted soils. Test boring TB-2 was performed within the release area, directly below the former AST. Test boring TB-3 was performed in the driveway of the subject dwelling on the opposite side of the house in a down-gradient location. Field screening of soil samples collected from TB-2 reported organic vapor concentrations ranging from 157 to 199 ppmv increasing with depth up to and including the 12-16' interval. Soil samples collected from below 16' exhibited decreased PID readings from 8-15 ppmv, with slight increase at groundwater interface. Soil samples collected from TB-3, reported no concentrations of organic vapors above background. V � x� c J®r S• - Photo 2: Location of BEA test boring (TB-2) and the monitoring well (MW-2) as within release area under former above ground oil tank. A single soil sample from the area of impact (TB-2:12-16) was prepared and submitted to R.I. Analytical laboratory for EPH/4 target PAHs and VPH/BTEX analysis. Analytical results, received May 5, 2017, reported EPH/PAH and VPH/BTEX concentrations greater than the applicable Method 1 Risk Characterization standards.

The property owner later contacted BEA to notify them that the Insurer had changed their position and was now offering coverage of the release, as a covered loss. BEA subsequently received full engagement to provide LSP Oversight and professional services toward development and implementation of an IRA Plan. On May 30, 2017, BEA personnel returned to the site to collect additional data on the lateral extent of soil impact. BEA personnel performed three hand borings in the vicinity of the release area in an attempt to determine the limits of significant impact. Hand boring HB-1 was advanced northeast of the release area, HB-2 was advanced southwest of the release area, and HB-3 was advanced northwest of the release area. Refusal was met at 10' below grade in HB-1, and 6'below grade in HB-2 and HB-3, due to rocks. Low PID readings (<3 ppmv) were reported in HB-1. Elevated PID readings from 40.3 ppmv to 20.4 ppmv were reported in HB-2, decreasing with depth. No PID readings were reported in HB-3 above the instrument detection limit (Non-Detect). Based on the limited amount of data collected from relatively shallow depths, no samples were submitted to the laboratory from these assessment activities. Nevertheless, this information was used to re-define the area of soil impact for the proposed soil AUGUST 2,2017 ENNES:2 GENERAL PATTON DR.BEA17-11006 PAGE 7 OF 12 RvINIEDIATE RESPONSE ACTION STATUS I,RTN 4-26544 removal activities. Based on the refusals encountered during the hand borings, additional test borings were proposed in order to collect soil samples at greater depths. The IRA Plan was filed on June 12, 2017. The IRAP called for the mechanical removal of up to 100 cubic yards of impacted soils in a 16' x 10' area to 15' deep. As a contingency against residual impact, Part A of the two-part Regenesis RegenOx ® in-situ chemical oxidant (ISCO) would be applied to soils in the bottom of hole area, with an infiltration system installed prior to backfilling, for the potential application of Part B. Soil samples collected at the extent of the excavation would be collected for laboratory analysis. Groundwater sampling with laboratory analysis would continue quarterly to monitor groundwater conditions at the site. SUPPLEMENTAL ASSESSMENT On June 22, 2017, BEA returned to the site with Bronson Drilling of Winchester, MA, to install two additional groundwater monitoring wells and to perform additional soil assessment in the release area. Test boring TB-4 was advanced in the front of the house, in a down-gradient location, and was completed as monitoring well MW-4. Test borings TB-5 and TB-6 were advanced to the north and south of the release area, respectively. Test boring TB-7 was advanced west of the release area and was completed in an up-gradient location, as monitoring well MW-5. The test borings were performed using a direct-push-type drilling rig. Four-foot composite soil samples were collected in Shelby tubes and then placed in an 8-ounce glass jar, sealed with an aluminum septum, then agitated to develop organic vapors. Each sample was subsequently screened with a PID by "jar headspace method" consistent with the Interim Soils Policy (WSC- 94-400). Field screening of a soil sample collected from TB-4 at the groundwater interface reported no concentrations of organic vapors above the instrument detection limit (Non-Detect). Field screening from Test boring TB-5 reported organic vapor concentrations ranging from 22.8 to 23.3 from 6-12' below grade, 154 in the 12-16' interval, 0.3 ppmv in the 16-20' interval, and ND in the 20-24' interval at the groundwater interface. Soil samples collected from TB-6 and TB-7 reported no concentrations of organic vapors above background [Refer to Borehole Logs — Appendix B]. Based on its location within the release area, monitoring well MW-2 was also checked for the accumulation of light non-aqueous phase liquid (LNAPL) during this site visit. A sample of water was collected with a dedicated bailer and emptied into a glass jar. Small globules of LNAPL were observed in the water sample after emptying the in the jar. Three soil samples from TB-5 (TB-5: 6-12', TB-5: 12-16' and TB-5: 16-20) and a single soil sample from TB-6 (TB-6: 6-16') were submitted to a MA certified laboratory for EPH/PAH and VPH/BTEX analysis. The results, received on July 3, 2017 reported trace concentration of fractional VPH and EPH, below the most stringent S-1/GW-1 Method 1 Standards, in the TB-5: 12-16' sample. The remaining soil samples reported all concentrations of EPH/PAHs and VPHIBTEX as Non-Detect. These results confirmed the proposed extent of soil removal in a 16' x 10' area. The results are summarized below in Table 3.

During the sampling event, the wells were purged and sampled via low-flow methodology, wherein the samples were collected for EPHNPH and target analyte concentrations upon meeting purge requirements and the stabilization of field parameters (pH, Dissolved Oxygen, Conductivity, Temperature). The samples were collected in appropriately preserved laboratory containers and placed on ice in a cooler. The top-of-casing elevations of all monitoring wells were then surveyed to a common vertical datum, towards the qualification of local groundwater flow direction. Static water level measurements demonstrated a site-specific groundwater flow to the southeast, consistent with regional flow. Based on the groundwater flow direction calculated, monitoring well MW-4 (and most likely MW-3) is in a down-gradient location. Monitoring well MW-2 was again checked for the accumulation of LNAPL. An interface probe was used to check for accumulated product thickness. No measurable product thickness was noted. A sample of water was again collected for a visual check with a heavy petroleum sheen observed on the sample collected. Prior to departing the site, an absorbent sock was installed in monitoring well MW-2 for the passive collection of product AUGUST 2,2017 ENNES:2 GENERAL PATTON DR.BEA17-11006 PAGE 9 OF 12 IMMEDIATE RESPONSE ACTION STATUS I,RTN 4-26544 Laboratory analytical results were received on July 11, 2017. The results reported all EPH/PAH and VPH/BTEX concentrations in monitoring wells MW-4 and MW-5 as ND, wherein the reporting limits were less than the applicable GW-1 and GW-3 Method 1 Risk Characterization standards. RISK CHARACTERIZATION/IMMINENT HAZARDS [Refer to Appendix E] As presented, the S-1, S-2 and S-3 (GW-1/GW-3) soil categories are applicable in consideration of Method 1 Risk Characterization, as consistent with the provisions of 310 CMR 40.0933. These standards were developed to evaluate potential ingestion, particulate inhalation, dermal contact and in consideration of potential leaching of contaminants to groundwater as based on accessibility, frequency and intensity of use of the soils. Likewise, groundwater is divided into the GW-1 (ingestion), GW-2 (inhalation) and GW-3 (dermal contact and environmental impacts). Soil Laboratory analysis has reported fractional EPH and VPH compounds and target analytes naphthalene and 2-methylnaphthalene above applicable Method 1 Risk Characterization standards in soils at the Site. These soils represent a potential exposure threat to identified human and environmental receptors. As such,remedial response actions are prescribed under the IRAP to absolve potential exposure risks and to meet regulatory closure objective, without limitation of activities or use of the property. As previously reported, the fuel oil contaminated soils are currently isolated from human receptors by the way of the plastic sheeting covering the area of release. Furthermore,the plastic sheeting restricts the leaching of soil impacts, though impacts in the worst-case area at TB- 2/1\4W-2 have infiltrated to groundwater already. Regardless, based on the engineering controls, the restricted access to significant impacts, and the laboratory data reported under Method 1 Risk Characterization, no Imminent or Substantial Hazards are apparent nor is any Critical Exposure Pathway complete under current soil conditions as will continue to be evaluated. Groundwater Based on the PDWSA designation and proximity to groundwater, the GW-1 and GW-3 groundwater categories are considered applicable in consideration of Method 1 - Risk Characterization standards, as consistent with the provisions of 310 CMR 40.0932. The initial groundwater sampling event at the MW-2 location, within the release area reported fractional EPHNPH and target PAH impact exceeding the applicable and most restrictive GW-1, Method 1 Risk Characterization standard. The initial groundwater sampling event at the MW-1 location reported trace concentrations of PARS below the GW-1 Standards. Groundwater sampling at MW-3, MW-4 and MW-5 have reported all concentrations of petroleum hydrocarbons as ND. As such, groundwater data indicates impact is localized to the area directly below the former tank adjacent to the house, and that such impact is less than the I AUGUST 2,2017 ENNES:2 GENERAL PATTON DR.BEA17-11006 PAGE 10 OF 12 INIIviEDIATE RESPONSE ACTION STATUS I,RTN 4-26544 applicable GW-2 and GW-3, Method 1 standards. Based on municipal water supply provided to the subject property and surrounding area and the relatively low concentrations of the reported groundwater impact, no Imminent or Substantial Hazards are reported under existing conditions, with respect to the significant groundwater impact. Indoor Air Indoor air quality in the basement and first floor living space was screened with a calibrated PID during the initial assessment. During the screening, no concentrations of organic vapors were reported above the detection limits of the instrument. No fuel oil odor has been reported in the living space or basement of the dwelling. Based on the indoor air quality screening and olfactory observations, no apparent Imminent or Substantial Hazards are reported under existing Site conditions. The need for soil vapor testing or indoor air testing will be evaluated based on the concentrations of volatile organic compounds (VOC) reported in end- point soil samples and representative groundwater samples, collected following the completion of contaminated soil removal. Such evaluation criteria are consistent with the provisions of 310 CMR 40.0942(1) (d) and the MA DEP Vapor Intrusion Guidance document (Policy WSC-16- 435). PROPOSED RESPONSE ACTIONS As previously indicated in the IRA Plan, up to 100 yards of impacted soils will be mechanically removed from the release area. The excavation will be facilitated by shoring the building with resistance piers and/or steel beams and a shoring box to advance the excavation vertically up to 15' below grade. During soil removal, field PID screening and Dexsil testing will be used by BEA to provide technical guidance and assist contaminated soil removal. When field testing indicates effective removal of significant impacts to the stated objective depth or as limited by safety concerns, soil samples will be collected from the extent of excavation for VPH/BTEX and EPH/PAH analyses. Prior to backfilling, 400 lbs. of RegenOx Part A will be mixed into the bottom of hole soils and an infiltration system, constructed of 4" perforated PVC pipe, will be set in washed stone in the bottom-of-hole area and installed concurrent with backfill [Refer to Site Plan]. A 4" solid piece of PVC riser will be plumbed to the lateral components and completed above ground with a Y fitting. The infiltration system will be capped with filter fabric to maintain the porosity and permeability of the stone aggregate. The infiltration system will provide the infrastructure to deliver 240 lbs. of RegenOx, Part B if desired, subject to submittal of IRA Modification and/or receipt of written approval by the Department. PROPOSED FUTURE MONITORING Subsequent to soil removal activities, BEA will continue to monitor groundwater at the site quarterly for EPH/VPH and target analytes, as appropriate. The further treatment of soils and/or groundwater will be evaluated from the results of future quarterly groundwater monitoring and indoor air screening and testing of the infiltration system. Monitoring wells MW-3, MW-4 AUGUST 2,2017 ENNES:2 GENERAL PATTON DR.BEA17-11006 PAGE 11 OF 12 DAMEDIATE RESPONSE ACTION STATUS I,RTN 4-26544 and MW-5 will be sampled for baseline wet chemistry analyses, in consideration of remedial additive application (RegenOx Part B). This testing includes laboratory analysis of iron, sodium, sulfate, calcium, magnesium and hardness, consistent with the chemical properties of the RegenOx product. 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. PID screening of indoor air will continue in consideration of vapor entry, wherein all impacted soils are intended to be excavated from the prescribed vertical and horizontal distance associated with potential vapor entry. The need for sub-slab soil vapor or indoor air sampling in consideration of vapor entry will be made based on results of soil analyses, PID screening results and observations made following soil removal and quarterly groundwater sampling, under "lines of evidence" considerations. 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. Future environmental assessment/monitoring activities will dictate the need for any additional remedial measures to be represented in future IRA Status reports as will be filed every six months until an IRA Completion Report is filed. Remedial response activities considered herein, and potentially to follow in subsequent IRA Status reports, are intended to mitigate all Critical Exposure Pathways (CEPS) and to facilitate a Permanent Solution in order to avert all potential risks to identified human and environmental receptors, in support of project closure. CONCLUSIONS The IRA Status I, represented by this filing, confirms the proposed IRA Plan will rely on mechanical removal of up to 100 cubic yards of impacted soils from within the release area. At the completion of soil removal activities, 400 lbs. of Regenesis ©RegenOx Part A will be mixed with bottom of hole soils. This work is intended to eliminate the contaminant source in all accessible and potentially accessible areas, and facilitate the construction of appurtenances that can be utilized for treatment of residual hydrocarbons. Laboratory analysis of end-point soil samples will be used to qualify exposure risks in consideration of a permanent solution without restriction to activities or use of the property. If laboratory analysis indicates that significant soil impacts remain within the excavation, 2401bs. of RegenOx part B will be applied to activate the Part A,mixed in to bottom of hole soils. Quarterly groundwater monitoring will continue to qualify potential impacts to the shallow aquifer associated with the subject release. Based on the analytical results of end-point soil samples, soil vapor testing and/or indoor air testing may be conducted to qualify the potential for vapor intrusion and associated exposures. At the time of this report, temporary structural shoring has been installed and contaminated soil is scheduled to begin within days. The next IRA Status Report (IRAS II) or IRA Completion with a Permanent Solution Statement (PSS) will be submitted within 6 months of this filing to document soil removal and environmental monitoring activities. If necessary, i AUGUST 2,2017 ENNES:2 GENERAL PATTON DR.BEA17-11006 PAGE 12 OF 12 IMMEDIATE RESPONSE ACTION STATUS I,RTN 4-26544 subsequent IRA Status Reports will be filed every six months thereafter, until a preponderance of physical evidence supports a condition of "No Significant Risk" as the basis of a Permanent Solution Statement without restrictions, in support of an IRA Completion. 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 Immediate Response Action Transmittal Form (BWSC-105). The LSP Opinions are based on available data and regulations in effect at the time of this reporting specific to the subject Site.

(BEA)has prepared the following Release Notification and Immediate Response Action Plan (IRAP) and Supporting Documentation, as a summary of release discovery, environmental assessment, and remedial response actions conducted since initial verbal Release Notification on February 25, 2017 on behalf of the Warner and Rosemarie Ennes as the owners of the property, and named PRP. Immediate Response Actions were undertaken to evaluate the presence of any Imminent Hazards, and to mitigate potential human exposures and environmental impacts associated with the sudden release of a reported 250 gallons of No. 2 heating fuel from an exterior above ground storage tank (AST), located adjacent to the dwelling. The tank was discovered actively leaking by the homeowner who smelled a petroleum odor near the tank, shortly after the tank was filled. In this initial reporting period, response actions have included the application and removal of absorbent materials from below the tank, and assessment activities including the performance of soil and groundwater sampling at the property by others. Subsequent to reviewing the work performed by the Insurer's consultant, BEA believed the premise to deny coverage was flawed by selective sampling. BEA, under limited authorization, then conducted additional soil and groundwater testing on behalf of the property owners, who had filed Financial Inability. This work reported concentrations of fractional extractable petroleum hydrocarbons (EPH) and volatile petroleum hydrocarbons (VPH) in soils from the surface to approximately 15' below grade surface (bgs), grossly impacted by fuel oil, as significantly above the applicable Method 1 Risk Characterization Standards. Additionally, sampling of monitoring wells installed by BEA reported groundwater impacts above the applicable Method 1 Risk Characterization Standards. Based on these results, the Insurer has agreed to extend coverage and BEA has since been engaged as LSP of Record to continue work on remedial response, as an Immediate Response Action under RTN4-26544. As such,this initial reporting has been delayed; this report 1 EMERGENCY SPILL RESPONSE Q WASTE SITE CLEANUP & SITE ASSESSMENT 6 PERMITTING 6 SEPTIC DESIGN&INSPECTION WATER SUPPLY DEVELOPMENT,OPERATION&MAINTENANCE A WASTEWATER TREATMENT,OPERATION&MAINTENANCE f JUNE 7,2017 ENNES:2 GENERAL PATTON DRIVE-HYANNIS/BEA17-11006 PAGE 2 OF 12 11MIEDIATE RESPONSE ACTION PLAN:RTN 4-26544 intends to bring the project back into compliance and expedite cleanup activities moving forward. Supplemental environmental testing of soils was conducted recently and in consideration of this most recent work and the prior soil and groundwater analysis,proposed remedial response actions include the removal of the contaminant source in grossly impacted soils within a 15' (L)x 10' (W) area to up to depth of 15' bgs (85 yards). Subsequent to the completion of soil removal activities, up to 300 lbs. of Regenesis© RegenOx Part A will be mixed into soils in the bottom of the excavation as a contingency for further treatment of soils and/or groundwater as may be necessary. An infiltration system, constructed of 4" perforated PVC and set in washed stone aggregate will then installed, to provide flexibility for the potential addition of RegenOx Part B, which would activate the remedial additives to result in In-situ Chemical Oxidation (ISCO). The infiltration system also serves as a passive vent and preferential pathway for the evacuation of any residual organic vapors and enhances air flow to the subsurface to enhance microbial activity and natural attenuation of any residual soil impacts. The vent pipe will also facilitate PID screening of soil vapor in the area of soil removal, in consideration of potential vapor entry into the adjacent occupied residential structure. Based on PID screening and soil and groundwater analysis conducted to date, No Substantial or Imminent Hazards are apparent at the Site at this time. Such determinations and consideration of Critical Exposure Pathways (CEPS) will continue to be evaluated with the development of additional data though the next reporting period. Results of end-point laboratory soil analysis will dictate the need for any further remedial response activities to be outlined in an IRA Status Report to be filed within 60-days of this submittal. During any subsequent site visits, field screening for organic vapors will be performed within the dwelling and at the infiltration system vent in consideration of potential vapor intrusion and inhalation exposure risks, if volatile organic compounds (VOCs)remain within the prescribed horizontal and vertical setbacks framed under the provisions of 310 CMR 40.0942(1)(d). The present of VOCs within the prescribed setback be further qualified by APH testing and will be documented in a future IRA Status report submittals. Based on the practical extent of soil removal and bottom of hole analytical results, BEA may also request DEP permission to add Part B of the Regenesis RegenOx remedial additive via the installed infiltration system. It is understood that any addition of Part B is not allowed under the IRA Plan represented herein. If any such use the RegenOx Part B activator is intended for ISCO treatment, an IRA Plan Modification must be made and environmental monitoring for remedial additive use provided, under the provisions of 310 CMR 40.0046 and further prescribed as subject to written authorization. Any additional remedial measures beyond mechanical soil removal of up to 100 yards and the use of up to 300 lbs. of Regenox, Part B will be represented in future IRA Status reports filed within 60 days of this IRA Plan, and then at the original six month deadline (12/25/17), unless filed earlier.

This work has and will continue to precede 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. ENVIRONMENTAL CONDITIONS [Refer to Appendix A] The subject property, located at 2 General Patton Drive is located approximately 100 feet southwest of the intersection of Bearses Way and General Patton Drive in the village of Hyannis in Barnstable, MA(Latitude 410 39' 35"N and Longitude 700 17' 46"W) [Refer to Figure 1]. The property contains 0.19 acres of land area and is developed by a one-story ranch-style dwelling constructed in 1950. The Site, as that portion of the subject property where fuel oil was released or came to be located, is on the north central side (rear) of the dwelling as a small portion of the subject property as currently estimated as less than 500 SF of land area. The surrounding area is heavily developed in similar residential use, with commercial businesses to the north along Falmouth Road (Route 28). Access to the subject property is unrestricted, with high frequency/high intensity of use, and children potentially present. Access to the area of release is also unrestricted, with high frequency/high intensity of use. The occupants, on-site workers and visitors to the property are identified as the primary human receptors to potential inhalation and dermal contact exposures associated with soil impacts. The subject property .occupants and abutters are included relative to the potential exposures associated with off-site migration of groundwater. The primary environmental receptor is Hyannis Inner Harbor, located approximately one mile south east of the site. Hydrologic references indicate groundwater exists below elevation 30'NGVD, within 20' of ground surface. Regional groundwater contours indicate a southeasterly flow direction towards the Hyannis Inner Harbor, located approximately one-mile southeast of the Site [Refer to Figure 2]. Through subsurface investigations performed at the site, groundwater has been measured at approximately 21'below grade. Additional subsurface work proposed at the site will include the installation of an additional groundwater monitoring well and the determination of site-specific groundwater flow direction. According to the Mass GIS Priority Resource Map, the subject property is not located within the Zone 11 Protective Radius of a Public Water Supply (PWS) well, nor is it located within the Zone A Protective Radius of any surface water reservoir. The Site and immediately surrounding area to the south and west are shown within a Medium-Yield Potentially-productive f JUNE 7,2017 ENNES:2 GENERAL PATTON DRIVE-HYANNIS/BEA17-11006 PAGE 4 OF 12 IMMEDIATE RESPONSE ACTION PLAN:RTN 4-26544 aquifer and within an EPA-designated sole source aquifer, as is all land area east of the Cape Cod Canal. As such, the Site and surrounding area are located within a Potential Drinking Water Source Area (PDWSA). A Non-Potential Drinking Water Source Area (NPDWSA) is shown north and east of the site, across Bearses Way. The NPDWSA is also located further to the south and west of the site. The map also shows freshwater wetlands approximately 1,000-feet north of the site and approximately one-half mile south of the site. In addition,the Priority Resource Map also shows two schools within a one-half mile radius of the site [Refer to Figure 3]. As such, based on the location of the property within a PDWSA and the depth to groundwater,the Site is currently subject to the GW-1, Method 1 Risk Characterization standards in consideration of "significant risk" pursuant to 310 CMR 40.0932. Based on the depth to groundwater (> 15'), it appears that the GW-2 standards are not applicable but be considered in the "lines of evidence" evaluation of vapor entry under Method 3. Additionally, based on potential significant environmental impacts and dermal contact exposures, the GW-3 Method 1 Risk Characterization standards do apply and are considered. Based on Site conditions relative to frequency/intensity of use and accessibility of soils, the S-1/S-2/S-3 (GW-1/GW-3) Method 1 — Risk Characterization standards are applicable to soil impacts in the qualification of"significant risk", in accordance with the provisions of 310 CMR 40.0975. Furthermore, in consideration of all potential foreseeable future exposures, the most restrictive S-1/GW-1, Method 1, Risk Characterization standard is used in consideration of ingestion, inhalation and dermal contact exposures and significant environmental impacts. BACKGROUND [Refer to Appendix B] The morning of February 25, 2017, the homeowner, Ms. Rosemarie Ennes observed a petroleum odor towards the rear of the building. Upon checking the outside aboveground fuel oil storage tank (AST), Ms. Ennes observed oil actively leaking from the tank. Ms. Ennes immediately called her fuel oil supplier (Scudder Taylor) and the Barnstable Health Department, both of whom responded to the property. Scudder Taylor personnel were able to stop the leak with a magnetic patch; however, the fuel gauge indicated the tank was already empty. Based on the date the tank was last filled(139 gallons on 2/23/17), with a minimal amount of oil remaining in the tank, it is estimated that the tank released approximately 250 gallons before the leak was stopped. Barnstable Health Department personnel (Donna Miorandi, Health Agent) contacted the Hyannis Fire Department and MA DEP to report the sudden release of fuel oil. MA DEP personnel (Peter Russel) then contacted Ms. Ennes to consult with the homeowner regarding remedial response liability under the Massachusetts Contingency Plan (MCP). Ms. Ennes then indicated that she would contact emergency response contractor NRC/ENPRO to request that they respond to the release. MA DEP personnel later responded to the release to meet with the homeowner and to assess the release. MA DEP records (BWSC-102) indicate that there was a mild odor near the RUNE 7,2017 ENNES:2 GENERAL PATTON DRIVE-HYANNIS/BEA17-11006 PAGE 5 OF 12 IMMEDIATE RESPONSE ACTION PLAN:RTN 4-26544 tank, but no odor in the basement of the dwelling and no evidence of impact to a storm drain at the corner of the property. MA DEP personnel later departed the scene upon the arrival of the NRC/ENPRO crew, who swept up the granular absorbent applied by the Hyannis Fire Department and constructed a poly-sheeting tent over the impacted area. Ms. Ennes contacted BEA on March 17, 2017, to request LSP oversight, as instructed by MA DEP personnel. BEA Licensed Site Professional (LSP) David Bennett requested to be kept updated subsequent to scheduled field testing as was being provided by the Insurer. ENVIRONMENTAL ASSESSMENT/PRELIMINARY RESPONSE [Refer to Appendix B] The homeowner's Insurer (Liberty Mutual) contracted EnviroTrac, Ltd. to investigate the release. On March 22, 2017, EnviroTrac personnel performed a single test boring some 4' outside the area of soils staining and installed a single groundwater monitoring well. Continuous soil sampling and PID screening was conducted from the surface to the groundwater with a maximum PID reading of 160 ppmv reported in the 8-10' interval and 54.3 ppmv at the groundwater interface at 23'. A single soil sample (MW-1 24') was submitted to SGS Accutest Lab for EPHAPAHs and VPH/BTEX analysis as below groundwater. Additionally, the monitoring well (MW-1), set at the boring location, was collected and submitted to Accutest for EPH/4PAHs and VPH/BTEX analysis. w.� } ar d _ � f � , t Y _ A- 4 , 14, ' Photo 1:View of subject AST with monitoring well MW-1 in foreground. JUNE 7,2017 ENNES:2 GENERAL PATTON DRIVE-HYANNISBEAI7-11006 PAGE 6 OF 12 MMIEDIATE RESPONSE ACTION PLAN:RTN 4-26544 Upon review of the data, BEA responded directly to Liberty Mutual regarding the testing performed. BEA noted that the test boring and monitoring well (MW-1) were installed outside of the area of release and placed in a location up-gradient of regional groundwater flow. The failure to select a representative location was evidenced by the fact that there was no significant PID readings until 8-10' below grade (see EnviroTrac borehole log). Elevated PID readings persisted to depth and then increased at the groundwater interface, typical of fuel oil migration through the unsaturated soils, and accumulating on the groundwater interface. In addition, it was noted that the only soil sample submitted did not correspond with the elevated PID readings observed, or the groundwater interface, but was collected from below the groundwater interface at 23' below grade. Regardless, the soil sample did report fractional EPH and VPH compounds, indicating fuel oil impact to groundwater, as did the groundwater sample. BEA believed these results clearly indicated soil impact to the groundwater interface impacting groundwater. However, the sample selection for soil and groundwater did not consider the spatial locations of soil impacts as outside the area of soil staining, or the solute fate of groundwater, and under the Representativeness Evaluation and Data Usability Assessment (REDUA), and did not give a clear picture of environmental conditions as the basis of Insurer's denial of Coverage. It was further communicated that the Insurer's position was also inconsistent with case law, wherein a 250 gallon release in sandy soils with shallow groundwater by itself represented an Imminent Threat of groundwater impact. On behalf of the property owners, BEA then requested they reconsider insurance coverage based on the flawed assessment previously performed by their consultant. The Insurer declined to reconsider coverage and took the position that no coverage would be afforded to the Insured unless groundwater impact was documented above GW-1 Standards. BEA subsequently contacted the property owner to propose additional assessment activities including soil borings and monitoring well installation to qualify previous testing results. The property owner agreed to pay for additional assessment activities and on April 28, 2017, BEA personnel arrived at the property with Bronson Drilling personnel, to perform soil borings and monitoring well installation activities. BEA arranged to have the tank removed and access cleared to the area of release for this testing. Two soil borings were performed at the site to determine the general nature and extent of impacted soils. Test boring TB-2 was performed within the release area, directly below the former AST. Test boring TB-3 was performed in the driveway of the subject dwelling on the opposite side of the house in a down-gradient location. The test borings were performed using a direct-push-type drill rig. Four-foot composite soil samples were collected by Shelby tubes and placed in an 8-ounce glass jar, sealed with an aluminum septum, then agitated to develop organic vapors. Each sample was subsequently screened by "jar headspace method" with a PID as consistent with the Interim Soils Policy (WSC-94-400).

The wells were purged and sampled via low-flow methodology, wherein samples were collected for EPH/VPH and target analyte concentrations upon meeting purge requirements and the stabilization of field parameters (pH, Dissolved Oxygen, Conductivity, Temperature). The samples were collected in appropriately preserved laboratory containers and placed on ice in a cooler. Laboratory analytical results of groundwater samples were received on May 11, 2017. The results reported concentrations of EPH/PAHs and VPH/BTEX in MW-2, including fractional C9-C10 Aromatics, Cll-C22 Aromatics and .2-Methylnaphthalene above the applicable Method 1 GW-1 Risk Characterization Standards.

Ms. Ennes later contacted BEA to notify them that the Insurer had changed their position and was now offering coverage of the release as a covered loss. BEA subsequently received full engagement to provide LSP Oversight and professional services toward development and implementation of an IRA Plan. On May 30, 2017, BEA personnel returned to the site to collect additional data on the lateral extent of impact. BEA personnel performed three hand borings in the vicinity of the release area in an attempt to determine the limits of significant impact. Hand boring HB-1 was advanced northeast of the release area, HB-2 was advanced southwest of the release area, and HB-3 was advanced northwest of the release area. Two foot composite. soil samples were JUNE 7,2017 ENNES:2 GENERAL PATTON DRIVE-HYANNISBEA17-11006 PAGE 9 OF 12 IMMEDIATE RESPONSE ACTION PLAN:RTN 4-26544 collected using a 3" stainless-steel bucket auger. The soil samples were then placed in an B- ounce glass jar, sealed with an aluminum septum, then agitated to develop organic vapors. Each sample was subsequently screened by "jar headspace method" with a PID as consistent with the Interim Soils Policy (WSC-94-400). Refusal was met at 10' below grade in HB-1, and 6' below grade in HB-2 and HB-3, due to rocks. Low PID readings (<3 ppmv) were reported in HB-1. Elevated PID readings from 40.3 ppmv to 20.4 ppmv were reported in HB-2, decreasing with depth. No PID readings (Non-Detect) were reported in HB-3 above the instrument detection limit. Based on the limited amount of data collected from relatively shallow depths, no samples were submitted to the laboratory from these assessment activities. Notwithstanding, this information was used to re-define the area of soil impact such as is represented herein and towards seeking shoring plans, towards soliciting contractor bids for planned soil removal activities. RISK CHARACTERIZATION/IMMINENT HAZARDS [Refer to Appendix E] As presented, the S-1, S-2 and S-3 (GW-1/GW-3) soils categories are applicable in consideration of Method 1 Risk Characterization, as consistent with the provisions of 310 CMR 40.0933. These standards were developed to evaluate potential ingestion, particulate inhalation, dermal contact and in consideration of potential leaching of contaminants to groundwater as based on accessibility, frequency and intensity of use of the soils. Likewise, groundwater is divided into the GW-1 (ingestion), GW-2 (inhalation) and GW-3 (dermal contact and environmental impacts) groundwater categories. For the purposes of risk characterization, the strictest S-1 (GW-l/GW-3), Method 1 Risk Characterization standards are also considered, in review of exposures related to foreseeable future uses and activities at the Site. Soil Laboratory analysis has established that fractional VPH compounds and the target PAH 2-methylnaphthalene exceed the applicable S-1, S-2 and S-3 (GW-3), Method 1 Risk Characterization standards in soils at the Site. These soils represent a potential exposure threat to identified human and environmental receptors. As such, remedial response actions are prescribed under the IRAP to absolve potential exposure risks and to meet regulatory closure objective, without limitation of activities or use of the properly. As previously reported, the fuel oil contaminated soils are isolated from human receptors by the way of the plastic sheeting covering the area of release. Furthermore, the plastic sheeting restricts the leaching of soil impacts, though impacts in the worst-case area at TB-2/MW-2 have apparently reached groundwater already. Regardless, based on the engineering controls, the restricted access to significant impacts, and the laboratory data reported under Method 1 Risk Characterization, no Imminent or Substantial Hazards are apparent nor is any Critical Exposure Pathway complete under current soil conditions as will continue to be evaluated. JUNE 7,2017 ENNES:2 GENERAL PATTON DRIVE-HYANNIS/BEA17-11006 PAGE 10 OF 12 IMMEDIATE RESPONSE ACTION PLAN:RTN 4-26544 Groundwater Based on the PDWSA designation and proximity to groundwater, the GW-1 and GW-3 groundwater categories are considered applicable in consideration of Method 1 - Risk Characterization standards, as consistent with the provisions of 310 CMR 40.0932. Groundwater has been measured at approximately 2l' below grade in the area of release. The initial groundwater sampling event at the MW-2 location, within the release area reported fractional EPH/VPH and target PAH impact exceeding the applicable and most restrictive GW-1, Method 1 Risk Characterization standard. The initial groundwater sampling event at the MW-1 location reported trace concentrations of PAHs below the GW-1 Standards. As such, groundwater data indicates impact is localized to the area directly below the former tank adjacent to the house and that such impact is less than the applicable GW-2 and GW-3, Method 1 standards. Based on municipal water supply provided to the subject property and surrounding area and the relatively low concentrations of the reported groundwater impact, no Imminent or Substantial Hazards are reported under existing conditions, with respect to the significant groundwater impact. Indoor Air Indoor air quality in the basement and first floor living space was screened with a calibrated PID during the initial assessment. During the screening, no concentrations of organic vapors were reported above the detection limits of the instrument. No fuel oil odor has been reported in the living space or basement of the dwelling. Based on the indoor air quality screening and olfactory observations, no apparent Imminent or Substantial Hazards are reported under existing Site conditions. The need for soil vapor testing or indoor air testing will be evaluated based on the concentrations of volatile organic compounds (VOC) reported in end point soil samples and representative groundwater samples, collected following the completion of contaminated soil removal. Such evaluation criteria are consistent with the provisions of 310 CMR 40.0942(1) (d) and the Interim Final Vapor Intrusion Guidance(Policy WSC-11-435). IMMEDIATE RESPONSE ACTION PLAN [Refer to HASP—Appendix F] The information from the assessment and evaluation of potential exposure risk represented by current soil and groundwater conditions was used to develop a remedial strategy for the mechanical removal of the significantly impacted soil and groundwater from the identified release areas. The preferred remedial strategy is to mechanically remove up to 100 yards of the impacted soils by shoring the building with resistance piers and/or steel beams, to hold the dwelling in place such that it is used as a primary residence. After the initial 4-6' of surficial soils is removed and lateral extent of soil impacts confirmed, a shoring box would then be constructed to vertically advance the excavation up to 15' below grade, as will be represented in structural engineering plans pending at the time of this filing. I i JUNE 7,2017 ENNES:2 GENERAL PATTON DRIVE-HYANNIS/BEA17-11006 PAGE 11 OF 12 HVINIEDIATE RESPONSE ACTION PLAN:RTN 4-26544 During soil removal, field PID screening and Dexsil testing will be used by BEA to provide technical guidance and assist contaminated soil removal. At which time field testing indicates effective removal of significant impacts to the stated objective depth or as limited by safety concerns, confirmatory end-point soil samples will be collected from the extent of excavation for risk-based VPHBTEX and EPH/PAH analyses. Upon the completion of soil removal and confirmatory soil sampling, up to 300 lbs. of RegenOx Part A will be mixed into the bottom of hole soils and an infiltration system, constructed of 4" perforated PVC pipe, will be set in washed stone along the bottom-of-hole area and installed concurrent with backfill [Refer to Site Plan]. A 4" solid piece of PVC riser will be plumbed to the lateral components and completed above ground with a Y fitting. The infiltration system will be capped with filter fabric to maintain the porosity and permeability of the stone aggregate. The infiltration system will provide the infrastructure to deliver RegenOx, Part B as may be desired subject to submittal of IRA Modification and receipt of written approval by the Department. Due to the location of MW-1 and MW-2 in the immediate vicinity of the release area, these wells will be destroyed during the excavation work. As such, two additional groundwater monitoring wells, MW-lR(up-gradient) and MW-4 (down-gradient) will be installed subsequent to the removal of significantly impacted soils. These new wells will be tested on installation, along with MW-3 for baseline wet chemistry in consideration of remedial additive application (RegenOx Part B). This testing includes laboratory analysis of iron, sodium, sulfate, calcium, magnesium and hardness, consistent with the chemical properties of the RegenOx product and manufacturer recommendations. The wells will also be sampled quarterly for EPH/VPH analysis and wet chemistry, at least twice through the calculated time of travel via low-flow methodology as collected upon meeting purge requirements and stabilization of field parameters (pH, Dissolved Oxygen, Conductivity, Temperature) [Refer to QA/QC—Appendix G]. Field PID screening of indoor air will continue in consideration of vapor entry, wherein all impacted soils are intended to be excavated from the prescribed vertical and horizontal distance associated with potential vapor entry. The need for additional APH testing of sub-slab soil vapor or indoor air in consideration of vapor entry will be made on soil/groundwater conditions, PID screening and observations made following soil removal and quarterly sampling, under"lines of evidence" considerations. CONCLUSIONS The Immediate Response Action Plan represented by this filing will employ an aggressive soil removal strategy for the excavation and recycling of up to 100 cubic yards of fuel oil contaminated soil from within the identified area of impact with contingency for the use of up 3001bs of RegenOx, Part A mixed into the bottom of hole soils. Field PID screening and Dexsil testing will be used by BEA personnel to provide technical assistance and direct excavation operations. This work is intended to eliminate the contaminant source in all accessible and potentially accessible areas, and facilitate the construction of an infiltration system that can be i JUNE 7,2017 ENNES:2 GENERAL PATTON DRIVE-HYANNIS/BEA17-11006 PAGE 12 OF 12 IMMEDIATE RESPONSE ACTION PLAN:RTN 4-26544 utilized for additional treatment of residual hydrocarbons through the introduction of RegenOx, Part be to support ICSO treatment, if necessary. End-point soil sampling, additional groundwater monitoring, and potentially soil vapor/indoor air testing will be used to evaluate treatment performance and qualify exposure risks and the need for further treatment of soils and/or groundwater. The objective of the IRA Plan is to achieve a condition of No Significant Risk for all foreseeable activities and uses of the property, without restriction, in support of a Permanent Solution and regulatory project closure. 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 Immediate Response Action Transmittal Form(BWSC-105). The LSP Opinions are based on available data and regulations in effect at the time of this reporting specific to the subject Site.
