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

basement floor of the subject dwelling while investigating abandoned fuel lines adjacent to the.
furnace and a separate area of concrete floor staining under the existing aboveground fuel oil
storage tank (AST). Laboratory analysis of representative soil samples from both areas reported
petroleum hydrocarbon impacts greater than RCS-1 Reportable Concentrations in at least 2 yards
of soils as triggering a 120-Day Reportable Condition. Further investigation outside the footprint
of the dwelling found an abandoned underground fuel oil storage tank (UST) off.the northeast
corner of the dwelling. Both the UST and the AST were subse uentl remo a Zed further
environmental assessment was conducte to qualify appropriate Notification and Remedial
`. Response actions wherein a threat of groundwater impacts was identified in a mapped Potential
Drinking Water Source (PDWSA — GW-1). Subsequent soil testing and analysis was used to
identify the horizontal and vertical extent of significant soil impacts as between both the interior
and exterior tanks wherein two separate historic releases are indicated. Based on the degree of
weathering and interviews with the surviving heirs of the owner, these releases are suspected as
being more than 10 years old. Groundwater analytical results show low level groundwater
impacts in the vicinity of the former UST (MW-1) but not in the down gradient wells. As such,
low level groundwater impact appears to be limited to the art elease as will continue to be
monitored throughout the RAM investigation.
Additionally, the performance of the RAMP relative to the mitigation of potential
exposure risks will further be evaluated by end point sampling of soils for EPHNPH analysis.
As dependent upon these results, sub-slab soil vapor sampling may be conducted to evaluate
potential vapor entry into the structure if residual volatiles are reported in the VPH analysis.
Initial groundwater gauging has established a southwesterly groundwater flow direction with
minimal tidal influence. Since monitoring well MW-3 is marginally outside the projected solute
pathway from the release area, an additional monitoring well is proposed to be installed further to
the west as immediately down gradient and adjacent to the release area as representative of any
down gradient impacts or release migration. This well will be sampled within 48 hours of
installation and again quarterly in August and October to evaluate seasonal groundwater
variations.
It is anticipated that soil removal proposed under the RAM can mitigate all significant
exposures risks and any potential critical exposure pathways in support of a Class A, Response
Action Outcome (RAO) as a permanent solution with a highest degree of confidence.
Notwithstanding, no warranty or guarantee of future performance is expressed or implied. It
must be recognized that environmental investigations are inherently limited in the sense that
conclusions are drawn and recommendations developed from the available information obtained
under the context of the regulations and standard of practice at the time of reporting.
This work has and will continue to be conducted under direct LSP oversight in a manner
consistent with the MCP Response Action Performance Standards (RAPS)pursuant to 310 CMR
40.0191 and the QA/QC policies of BENNETT ENVIRONMENTAL ASSOCIATES, INC. The
facts and statements herein are, to the best of our knowledge, a true and accurate representation
of the Site activities, remedial response actions and environmental conditions associated with the
project and LSP Opinions acknowledged by the certification on the attached BWSC-105
Transmittal Form.

ENVIRONMENTAL CONDITIONS [Refer to Appendix A]
The subject property at 142 Fifth Avenue is noted on Barnstable Assessor's Map 245 as
Parcel 113 and is located southeast of the intersection of Fifth Ave and Forest Street [Refer to
Figure 1] in the Barnstable Village of West Hyannisport. The UTM coordinates for the Site are
Northing 4610162m and Easting 390093m. The property contains approximately 0.27 acres of
land area and is developed by a one and a half-story residential dwelling and a free-standing
garage. The entire property is upland and relatively flat with approximate elevations ranging
from 20' NGVD in the northern portion of the property to approximately 18' NGVD along the
southern portion.
The surrounding area is heavily developed and in similar use as characterized by seasonal
and year-round residential properties. Access to the subject property and area of release is
unrestricted with high frequency/low intensity of use and children potentially present. The
dwelling occupants and visitors to the property are identified as the primary potential human
receptors to potential inhalation and dermal contact exposures.
Groundwater was encountered at 12-13' below grade_ surface. Regional groundwater
contours indicate a southwesterly flow direction toward a small unnamed stream and Centerville
Harbor farther west [Refer to Figure 2]. Site-specific groundwater contours were found to be
consistent with local flow direction. Based on groundwater flow direction, the small unnamed
stream represents the primary potential environmental receptor in consideration of Method 1 —
Risk Characterization for potentially receiving impacted groundwater.
Based on the MA DEP Priority Resources Map the subject property is not located within
the Zone II Protective Radius of a Public Water Supply (PWS), nor is it located within the Zone
A protective radius of any surface water reservoir. The Site is shown as a medium-yield
potentially productive aquifer as well as a part of the Sole Source Aquifer designated by the EPA
for all of Cape Cod east of the canal. As such, the Site is defined as within a Potential Drinking
Water Source Area (PDWSA). The Priority Resources Map shows an area of protected open
space southwest of the subject property across Fifth Ave. The Priority Resources Map also
shows salt and freshwater wetlands to the east, west and south of the Site, as well as NHESP
Estimated Habitat of Rare Wildlife in Wetland Areas.
Based on the PDWSA designation and proximity to groundwater, the RCGW-1-
Reportable Concentrations are applicable per 310 CMR 40.0361, as are the GW-1, GW-2 and
GW-3 Method 1 Risk Characterization standards in accordance with 310 CMR 40.0974. Based
on residential use and Site conditions including frequency/intensity of use and accessibility of
soils, the RCS-1 Reportable Concentrations are applicable per 310 CMR 40.0362, and S-1/S-2/S-
3 (GW-1/GW-2/GW-3), Method 1 — Risk Characterization standards are applicable per 310
CMR 40.0975. These standards were developed in consideration of potential ingestion,
inhalation, and environmental exposures, and in review of potential leaching of contaminants to
groundwater. In review of potential future use of the property, the strictest S-1 (GW-1) criteria
are considered under Method 1 Risk Characterization.

BACKGROUND [Refer to Appendix B]
During a home inspection for a pending real estate transaction, the home inspector noted
subsurface copper lines, adjacent to an exterior wall, in the northeastern portion of the basement.
BEA was.subsequently contracted by the potential buyer's realtor to investigate the utility of the
copper lines. As such, BEA personnel traveled to the subject property on May 7, 2013 to
investigate the presence of an abandoned UST and to perform hand borings in the area of the
copper lines to determine if a release of fuel oil had occurred. Upon arriving at the property,
BEA personnel probed the ground adjacent to the northeast corner of the dwelling for signs of an
underground tank. A large object, with the approximate dimensions similar to a typical 275-
gallon fuel tank was located approximately 2' below grade in this location. A hole was dug and it
was confirmed that the object was a steel UST. BEA personnel then went to the basement to
perform.hand borings to assess subsurface soils. Upon entering the basement, petroleum staining
was observed beneath the existing AST servicing the heating system, representing another
possible release of fuel oil to the subsurface. As such, a series of hand borings were advanced to
investigate subsurface conditions below the basement slab (Refer to Site Plan).
BEA conducted two hand borings (HB-1 and HB-IA) in the area of the AST. HB-1 was
angled beneath the tank to the west, perpendicular to the interior basement wall. HB-lA was
angled beneath the tank to the northwest, towards the corner of two interior basement walls,
where the staining was greatest. Hand boring HB-2 was advanced in the northeastern portion of
the basement adjacent to the subsurface copper lines. The hand borings were advanced with a
stainless steel bucket auger with soil samples collected in 2' intervals. The samples were then
placed in 250-milliliter glass jars with aluminum septa and agitated to develop organic vapors.
The samples were subsequently screened by "jar headspace method" with a PID
[ThermoEnvironmental 580B OVM (10.8 eV lamp)] as consistent with the Interim Soils Policy
(WSC-94-400). PID screening reported elevated organic vapor concentrations < 30 parts per
million by volume (ppmv) in H13-1/1-1134A and < 67 ppmv in HB-2. BEA field preserved soil
samples HB-IA:2-4' and HB-2:4-6' on ice in a cooler for MA Certified laboratory analysis of
risk-based extractable petroleum hydrocarbon (EPH) and target polynuclear aromatic
hydrocarbon(PAH) concentrations.
Laboratory analysis reported concentrations of fractional C9-C18 Aliphatics and C11-C22
Aromatics greater than the applicable RCS-1 Reportable Concentrations in both soil samples
submitted. As such, laboratory analytical had demonstrated significant petroleum hydrocarbon
impact in more than two yards of soil, and, in the absence of evidence demonstrating a sudden
release, or elevated PID readings (>100 ppmv) in soils, a 120-Day Release Notification
requirement was triggered as the basis of remedial response liability.

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

Groundwater
To further qualify the 120-Day Reportable Condition and the appropriate regulatory
vehicle for Site cleanup, BEA furthered environmental characterization of the subject property on
June 19, 2013 with the advancement of test borings (TBs) for the installation of monitoring wells
(MWs) in review of potential groundwater impacts. BEA personnel directed Jenkins Well
Drilling in the advancement of TB-11, TB-12 and TB-13 towards the installation of monitoring
wells MW-1, MW-2 and MW-3, respectively. Test Boring TB-11 was advanced off the
northeast corner of the dwelling, in the area of the former UST; TB-12 was advanced south of the
dwelling and TB-13 was advanced southwest of the dwelling (Refer to Site Plan). The wells
were finished in water-tight road boxes with locking gripper plugs. Top-of-casing elevations
were also surveyed to a common vertical datum in review of static water level elevations towards
calculating local groundwater flow.
Field headspace screening of soil samples collected from the test borings reported low

RISK CHARACTERIZATION/IMMINENT HAZARDS [Refer to Appendix E]
Soil
As presented, the RCS-1 Reportable Concentrations, as well as the S-1, S-2 and S-3
(GW-1/GW-2/GW-3) soils categories are applicable in consideration of Method 1 Risk
Characterization. Laboratory analysis has confirmed the presence of Cll-C22 fractional
JULY 19,2013 IDLEWILD TRUSTBEAI3-10551b
PAGE 10 OF 13 RELEASE ABATEMENT MEASURE PLAN/RTN 4-24663
aromatics and C9-C18 Aliphatics, as well as 2-methylnaphthalene, as exceeding the RCS-1
Reportable Concentrations as well as the S-1/GW-1 Method 1 —Risk Characterization standards.
As such, remedial response and waste site cleanup activities are prescribed under the RAMP to
absolve potential exposure risks and to meet regulatory closure objective without limitation of
ctivities or use of the property.
Groundwater
As presented, the RCGW-1 Reportable Concentrations, as well as the GW-1, GW-2 and
GW-3 groundwater categories are applicable in consideration of Method 1 Risk Characterization.
These standards were developed to evaluate potential ingestion (GW-1), inhalation (GW-2) and
environmental (GW-3) exposures. Groundwater sampling and associated laboratory analysis
have reported no_ significant impacts above GW-1 Standards in any of the on-site monitoring
wells. However, based on groundwater gauging and site-specific groundwater flow calculations
it has been determined that there are no groundwater monitoring wells that are within a
definitively down gradient position. As such, one additional monitoring well is prescribed within
the RAMP.
Indoor Air
Indoor ambient air quality within the living space of the residence was screened during
the initial Site inspection on May 5, 2013 and has been monitored during subsequent Site visits.
The screening has been conducted utilizing a pre-calibrated PID with a 10.6 or 11.8eV lamp.
Each indoor air screening event has reported no detectable petroleum odors and background
TOV concentrations (<0.1 ppmv) in the dwelling basement. No additional testing has been
conducted at this time as the dwelling is currently unoccupied.
Indoor air quality will continue to be monitored during subsequent Site inspections for
worker safety. During soil removal operations a vapor barrier will be installed between the
basement and living area with active ventilation provided. As part of the RAM, all impacted
flooring will be removed and replaced inside the dwelling as eliminating interior sources of
organic vapors. Pursuant to the Interim Final Vapor Intrusion Guidance (Policy WSC-11-435),
as well as anticipated revisions to the MCP, Air-phase Petroleum Hydrocarbon (APH) testing of
representative soil vapor beneath the concrete basement slab will supplement the PID screening
towards the development of multiple lines of evidence to evaluate potential vapor intrusion and
inhalation exposure risks, should residual volatile organic compounds be present within the
prescribed setbacks as framed in the provisions of 310 CMR 40.0942(1)(d).
Imminent Hazard Evaluation
Based on the assessment activities conducted to date, which indicate that all significant
fuel oil impacts remain at more than 9' below rg ade or beneath the footprint of dwelling, at which
time the dwelling has been largely uninhabited, no Imminent or Substantial Hazards have been
identified at the Site. Groundwater monitoring has reported no significant impacts associated
with the subject release, and the most recent indoor air quality screening has reported no TOV
concentrations within the dwelling above the sensitivity of the instrument (<O.1 ppmv).
JULY 19,2013 IDLEWILD TRUST/BEA13-10550
PAGE 11 OF 13 RELEASE ABATEMENT MEASURE PLAN/RTN 4-24663
Monitoring of groundwater, indoor air and soil vapor will continue in review of potential impacts
and risk characterization to evaluate potential hazards towards development of a preponderance
of physical evidence in qualifying exposure risks and demonstrating No Significant Risk.
RELEASE ABATEMENT MEASURE PLAN [Refer to Appendix E]
The information from the assessment of current soil and groundwater conditions was used
to develop a remedial strategy for the excavation of significantly impacted soils from the
identified release area noted on the site plan. This remedial strategy calls for the removal of the
concrete floor and impacted subsurface soils to a depth of up to 6' below the basement floor. It is
anticipated that as much of 60 cubic yards of impacted soil may be generated. Temporary
structural support of the chimney and northeast corner of the subject building will be installed by
a licensed contractor with appropriate permitting. Prior to the beginning of work the furnace will
be removed.
Subsequent to the shoring of the building, the environmental contractor will break up the
basement floor and properly dispose of any and all impacted concrete. The contractor will then
use an excavator to segregate and stockpile clean overburden material adjacent to the exterior
basement walls. Soil removal will then be advanced to depth from the north to the south. Soils
will be transported off site under an approved Bill of Lading for direct loading and transportation
to Aggregate Industries South Dennis asphalt batching facility.
Following the removal of significant soil impact as anticipated in the beginning of August
2013, confirmatory end-point soil samples will be collected for risk-based EPH/VPH analysis, or
for TPH analysis as a cost saving measure wherein field-testing indicates petroleum and volatile
impacts are clearly absent. After field screening has indicated that risk based closure objectives
have been met, a subsurface sub-slab venting/SVE system will be constructed and installed in the
excavated area of release. The venting system will be constructed of 4 x 4"perforated PVC pipe
laterals, as set in washed stone along the bottom-of-hole area. A 4" solid piece of PVC riser will
be plumbed to the lateral components and connected to a wind turbine for the passive venting of
residual volatile petroleum compounds. The venting system will also provide the flexibility to
deliver remedial additives, as may be necessary to mitigate significant residual soil impacts or for
any groundwater treatment.
If residual volatile compounds are reported in the end point samples as within 6'
horizontally and 10' vertically of the basement floor, a soil vapor probe will be installed and
tested for APH. APH analytical results will be compared with the sub-slab screening values set
forth in the Interim Final Vapor Intrusion Guidance document (Policy WSC-11-435). This
testing may be repeated to establish the prescribed "lines of evidence" rationale to evaluate
potential vapor entry into the occupied structure and related inhalation exposures.
The monitoring wells will be sampled quarterly in August and October 2013 following
soil removal. The quarterly groundwater analysis will be used to evaluate any residual petroleum
hydrocarbon impacts to groundwater. The further treatment of soils and/or impacted groundwater
will be evaluated from the results of end-point soil sampling and future quarterly groundwater
assessment. Specifications of potential remedial equipment, operations and maintenance, or use
JULY 19,2013 1DLEWILD TRUSTBEAI3-1055d
PAGE 12 OF 13 RELEASE ABATEMENT MEASURE PLAN/RTN 4-24663
of any remedial additives will be represented as a modification of the RAM, if applicable, to be
reported in subsequent RAM Status (RAMS) reports. All such work will be compiled on
"Inspector's Daily Record of Work Progress"reports and documented in a RAM Status Report or
RAM Completion Report to be submitted within 120 days of this filing.
CONCLUSIONS
The Release Abatement Measure Plan, represented by this filing, proposes the excavation
and disposal of up to 30 cubic yards of significantly impacted soils from the release area
identified on the Site Plan in Appendix A.
Under the RAM Plan, BEA will direct the segregation of clean overburden material
surrounding the dwelling to accommodate the excavation and disposal of.contaminated soils.
Field PID screening and Dexsil testing will be used by BEA personnel to provide technical
assistance and direct excavation operations. A subsurface venting system will be constructed and
set in washed stone aggregate prior to final restoration for venting of residual petroleum
hydrocarbons, and/or future remedial additive applications if necessary. This work is intended to
eliminate the contaminant source and associated exposure risks to identified human and
environmental receptors towards achieving a condition of No Significant Risk in support of a
permanent solution.
This work is scheduled to begin in the beginning of August 2013. A RAM Status Report
or RAM Completion Report with Response Action Outcome (RAO) will be submitted within
120 days of this filing. Any subsequent RAM Status Reports will be filed every six months
thereafter until a preponderance of physical evidence supports a condition of "No Significant
Risk" and RAO objectives are met as supporting an RAM Completion Report.
The findings of this investigation, as represented herein, set forth the rationale and
technical justification for the LSP Opinions offered, as established by the certifications made on
the attached Release Abatement Measure Transmittal Form(BWSC-106). The LSP Opinions are
based on available data and regulations in effect at the time of this reporting specific to the
subject Site.

SUPPORTING DOCUMENTATION
Residential Property—RTN 4-24663
142 Fifth Ave.—West Hyannisport, MA 02672
Dear Mr. Crafton,
BENNETT ENVIRONMENTAL ASSOCIATES, INC. (BEA) has prepared the following
Release Abatement Measure Status I Report (RAMSI) and Supporting Documentation, as a
summary of remedial response actions and environmental assessment and exposure risk
evaluation conducted since the filing of the Release Abatement Measure Plan (RAMP) on July
24, 2013. Formal Release Notification for the 120-Day Reportable Condition was previously
filed on July 10, 2013, to secure Release Tracking Number (RTN) 4-24663, towards the filing of
a RAMP for the implementation of remedial response actions to address the discovery of a
historic release of fuel oil. The RAMSI documents the completed response actions performed
towards contaminant source removal and subsequent environmental monitoring in review of
remedial performance and risk characterization. Information from the original RAMP is
summarized herein only to orient the reviewer to on-going response actions.
Remedial response actions conducted in the reporting period resulted in the removal and
remedial waste management of some 60 yards of fuel oil impacted soils from the qualified source
area as delineated by preliminary assessment activities. Endpoint soil sampling and analysis at
the extent of excavation reported effective removal of impacted soils in all areas with°the
exception of a sidewall area (SW-NW: 6-1 l') in Zone B of the excavation where additional soil
removal was not possible without endangering the structural integrity of the building although
extensive shoring was provided. Wherein all fractional EPHIVPH compounds and target analyte
concentrations where less than the most stringent S-1/GW-1, Method I — Risk Characterization
standards with the exception of this single sidewall area, under the provisions of 310 CMR
40.0926, and Exposure Point Concentration (EPC) was developed in review of exposure risks
and regulatory closure objectives. Under such considerations, 2-methynaphthatlene remained
above the S-11GW-1 leaching based standard of 0.7 mg/kg and further consideration of
alternative leaching based standards under Method 2 and Method 3 are being considered under
the provisions of 310 CMR 40.0983 to 40.0985. A preponderance of physical evidence has been
developed under Method 2 to evaluate the presence of any 2-methynaphthalene associated with

the historic release of fuel oil in down gradient monitoring wells. No such groundwater impacts
have been reported in the three rounds of groundwater sampling conducted and additional
quarterly groundwater sampling in the first quarter of 2014 will complete this Method 2
evaluation. Additionally, the use of the MA DEP Method 3 ShortForms considering both the
"worst case " discrete exposure and EPC, both produced Hazard Index (HI) and Excess Lifetime
Cancer Risk. indicating No Significantly Risk as associated with residual soil impacts at the
subject Site following soil removal.
Groundwater sampling and analysis through the reporting period showed no impacts in
down gradient monitoring wells. However, in MW-1 closest to the release area and adjacent to
the area of excavation, the most recent quarterly VPH/EPH analytical results reported
concentrations of EPH C11-C22 aromatics compounds in monitoring well MW-1 slightly greater
than the applicable and strictest GW-1, Method 1 Risk Characterization standards. At the time of
such sampling, the well had very little water as attributed to drought conditions and the sample
was very turbid. As such, an additional quarterly groundwater event is proposed herein to qualify
this residual impact over time wherein both filtered and unfiltered samples will be run for EPH
analysis if with increased available water,turbidity persists.
Indoor air quality screening was continued through the reporting period as supplemented
by sub-slab soil vapor testing following the completion of soil removal activities. Prior to
construction activities, a vapor barrier was constructed to isolate the unfinished basement area
from the living space and active ventilation used during the course of soil removal activities.
PID screening reported organic vapors as Non-Detect (ND < 0.2 ppmv) during work activities
with engineering controls and following the completion of work and replacement of the concrete
floor. A soil vapor probe was installed through the newly poured basement floor within the area
of excavation and APH samples collected using a summa canister in accordance with current
standard of practice and vapor intrusion policy WSC-11-435. Analytical results for both
sampling rounds report soil vapor concentrations for target volatile analytes as less than the
published threshold values. These lines of evidence further support a condition of No Significant
Risk associated with vapor entry and inhalation exposure risks.
Even though the area is serviced by town water and there are no known wells within 500'
of the Site, by definition as a potential drinking water source area (PDWSA), residual
groundwater impacts reported in monitoring well MW-1 could represent a potential ingestion
exposure risk, and as such additional groundwater sampling is appropriate and necessary in
review of potential exposure risks to human receptors. The additional round of groundwater
sampling will also support the Method 2 evaluation of alternative leaching based standards for 2-
rhethynphthalene. It is anticipated that with this additional round of sampling, potential
exposures risks can be qualified to document No Significant Risk to meet regulatory closure as a
permanent solution.
Such determinations continue to be evaluated with the development of additional data
and realization of Site conditions. Future environmental monitoring activities will dictate the
need for any additional remedial measures to be represented in future RAM Status reports. The
NOVEMBER 19,2013 IDLEWILD TRUST/BEA13-10550

ENVIRONMENTAL CONDITIONS [Refer to Appendix A]
The subject property at 142 Fifth Avenue is noted on Barnstable Assessor's Map 245 as
Parcel 113 and is located southeast of the intersection of Fifth Ave and Forest Street [Refer to
Figure 1] in the Barnstable Village of West Hyannisport. The UTM coordinates for the Site are
Northing 4610162m and Easting 390093m. The property contains approximately 0.27 acres of
land area and is developed by a one and a half-story residential dwelling and a free-standing
garage. The entire property is upland and relatively flat with approximate elevations ranging
from 20' NGVD in the northern portion of the property to approximately 18' NGVD along the
southern portion.
The surrounding area is heavily developed and in similar use as characterized by seasonal
and year-round residential properties. Access to the subject property and area of release is
unrestricted with high frequency/low intensity of use and children potentially present. The
dwelling occupants and visitors to the property are identified as the primary potential human
receptors to potential inhalation and dermal contact exposures.
Groundwater was encountered at 12-13' below grade surface. Regional groundwater
contours indicate a southwesterly flow direction toward a small unnamed stream and Centerville
Harbor farther west [Refer to Figure 2]. Site-specific groundwater contours were found to be
consistent with local flow direction. Based on groundwater flow direction, the small unnamed
stream represents the primary potential environmental receptor in consideration of Method 1 —
Risk Characterization for potentially receiving impacted groundwater.
Based on the MA DEP Priority Resources Map the subject property is not located within
the Zone lI Protective Radius of a Public Water Supply (PWS), nor is it located within the Zone
A protective radius of any surface water reservoir. The Site is shown as a medium-yield
potentially productive aquifer as well as a part of the Sole Source Aquifer designated by the EPA
for all of Cape Cod east of the canal. As such, the Site is defined as within a Potential Drinking

Water Source Area (PDWSA). The Priority Resources Map shows an area of protected open
space southwest of the subject property across Fifth Ave. The Priority Resources Map also
shows salt and freshwater wetlands to the east, west and south of the Site, as well as NHESP
Estimated Habitat of Rare Wildlife in Wetland Areas.
Based on the PDWSA designation and proximity to groundwater, the RCGW-1
Reportable Concentrations are applicable per 310 CMR 40.0361, as are the GW-1, GW-2 and
GW-3 Method 1 Risk Characterization standards in accordance with 310 CMR 40.0974. Based
on residential use and Site conditions including frequency/intensity of use and accessibility of
soils, the RCS-1 Reportable Concentrations are applicable per 310 CMR 40.0362, and S-1/S-2/S-
3 (GW-1/GW-2/GW-3), Method 1 — Risk Characterization standards are applicable per 310
CMR 40.0975. These standards were developed in consideration of potential ingestion,
inhalation, and environmental exposures, and in review of potential leaching of contaminants to
groundwater. 'In review of potential future use of the property, the strictest S-1 (GW-1) criteria
are considered under Method 1 Risk Characterization.
BACKGROUND [Refer to Appendix B]
During a home inspection for a pending real estate transaction, the home inspector noted
subsurface copper lines, adjacent to an exterior wall, in the northeastern portion of the basement.
BEA was subsequently contracted by the potential buyer's realtor to investigate the utility of the
copper lines. As such, BEA personnel traveled to the subject property on May 7, 2013 to
investigate the presence of an abandoned UST and to perform hand borings in the area of the
copper lines to determine if a release of fuel oil had occurred. Upon arriving at the property,
BEA personnel probed the ground adjacent to the northeast corner of the dwelling for signs of an
underground tank. A large object, with the approximate dimensions similar to a typical 275-
gallon fuel tank was located approximately 2' below grade in this location. A hole was dug and it
was confirmed that the object was a steel UST. BEA personnel then went to the basement to
perform hand borings to assess subsurface soils. Upon entering the basement,petroleum staining
was observed beneath the existing AST servicing the heating system, representing another
possible release of fuel oil to the subsurface. As such, a series of hand borings were advanced to
investigate subsurface conditions below the basement slab (Refer to Site Plan).
BEA conducted two hand borings (HB-1 and HB-lA) in the area of the AST, and an
additional boring in in the area of the copper lines (HB-2). HB-1 was angled beneath the tank to
the west, perpendicular to the interior basement wall. HB-lA was angled beneath the tank to the
northwest, towards the corner of two interior basement walls, where the staining was greatest.
Hand boring HB-2 was advanced in the northeastern portion of the basement adjacent to the
subsurface copper lines to investigate soil conditions in this location. The hand borings were
advanced with a stainless steel bucket auger with soil samples collected in 2' intervals. The
samples were then placed in 250-milliliter glass jars with aluminum septa and agitated to develop
organic vapors. The samples were subsequently screened by "jar headspace method" with a PID
[ThermoEnvironmental 580B OVM (10.8 eV lamp)] as consistent with the Interim Soils Policy
(WSC-94-400). PID screening reported elevated organic vapor concentrations < 30 parts per

million by volume (ppmv) in HB-1/HB-lA and < 67 ppmv in HB-2. BEA field preserved soil
samples HB-lA:2-4' and HB-2:4-6' on ice in a cooler for MA Certified laboratory analysis of
risk-based extractable petroleum hydrocarbon (EPH) and target polynuclear aromatic
hydrocarbon(PAH) concentrations.
Laboratory analysis reported concentrations of fractional C9-C 18 Aliphatics and C 11-C22
Aromatics greater than the applicable RCS-1 Reportable Concentrations in both soil samples
submitted. As such, laboratory analytical had demonstrated significant petroleum hydrocarbon
impact in more than two yards of soil, and, in the absence of evidence demonstrating a sudden
release, or elevated PID readings (>100 ppmv) in soils, a 120-Day Release Notification
requirement was triggered as the basis of remedial response liability.

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

preserved samples for extractable petroleum hydrocarbon (EPH + PAHs) and volatile petroleum
hydrocarbon(VPH+BTEX) laboratory analyses.
Laboratory analytical results, received June 14, 2013, reported fractional C9-C18
Aliphatics concentrations greater than the strictest S-1/GW-1 Method 1 Risk Characterization
Standards in samples collected from hand borings HB-4, HB-7 and HB-8. C l l-C22 Aromatics
concentrations also exceeded the S-1/GW-1 Standards in the sample collected from HB-8: 9-10'.
In addition, target analytes were reported above the S-1/GW-1 Standards in HB-4, HB-7, HB-8
and HB-9.

Drilling in the advancement of TB-11, TB-12 and TB-13 towards the installation of monitoring
wells MW-1, MW-2 and MW-3, respectively. Test Boring TB-11 was advanced off the
northeast corner of the dwelling, in the area of the former UST; TB-12 was advanced south of the
dwelling and TB-13 was advanced southwest of the dwelling (Refer to Site Plan). The wells
were finished in water-tight road boxes with locking gripper plugs. Top-of-casing elevations
were also surveyed to a common vertical datum in review of static water level elevations towards
calculating local groundwater flow.
Field headspace screening of soil samples collected from the test borings reported low
concentrations of organic vapors (<2.0) with the exception of TB-11/MW-1 where, in the 17-19'
interval a concentration of 18.2 ppmv was reported. A discrete sample at 19' bgs reported a
concentration of 38.7 ppmv. Representative soil samples TB-11: 11-13', TB-11@19' and TB-
13:11-13' were prepared and forwarded to a certified laboratory for confirmatory EPH with target
PAH analysis. Laboratory analytical results subsequently reported low-level fractional EPH
impacts in the TB-1 I@19' soil sample as well below the applicable S-1/GW-I Method 1 -Risk
Characterization standards. The balance of the test boring soil samples submitted reported all
EPH/PAH concentrations as ND wherein the reporting limits were less than the strictest S-

On June 25, 2013 BEA returned to the subject property to develop and sample the
monitoring well network in review of significant groundwater impacts. Groundwater samples
were collected for EPH/PAH and VPH/BTEX laboratory analyses. Laboratory analytical results
reported all EPHNPH and target analyte concentrations in all wells as non-detect, with the
exception of MW-1 wherein low level fractional EPH was reported below the applicable and
most stringent GW-1,Method 1 Risk Characterization standards.

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

residual fractional EPH impact reported along the north, east and west sidewall samples. The
Zone A Bottom of hole sample also reported modest fractional EPH,VPH and target analytes.
i
Zone B confirmatory soil samples reported all carbon range and target PAH
concentrations as less than the strictest S-1 (GW-1/GW-1/GW-3) Method 1 criteria with the
exception of the northwest sidewall adjacent to the chimney footing. Significant concentrations
of C9-C18 Aliphatics, 2-methylnaphthalene, Acenaphthene, C9-C10 Aromatics and Naphthalene
were reported above the strictest S-1 (GW-1/GW-1/GW-3) Method 1 Standards. The sum of
analytical results for soil samples collected from the extent of contaminated soil removal is
presented in the following Tables 5 and 6. The Tables present end-point sample data based on
soil category in order to develop applicable Exposure Point Concentrations to further qualify risk
characterization under Method 1, Method 2 and Method 3 Risk Characterization.

Groundwater Evaluation
BEA traveled to the site several times over the next few weeks to document Site
restoration with the installation of flowable fill to support the concrete block foundation. BEA
returned to the Site on September 5, 2013 to'perform sub-slab vapor monitoring and groundwater
monitoring in review of the remedial response performance. Static water level measurements
demonstrated a southwest flow direction as consistent with historic monitoring. BEA employed
low-flow sampling to monitor field parameters (temperature, pH, dissolved oxygen,
conductivity) with a calibrated YSI instrument to qualify potential fuel oil impact to shallow
groundwater. Upon parameter stabilization, each well was sampled for EPH/PAHs and
VPH/BTEX analysis. Due to the slow groundwater recharge at the Site, BEA personnel had to
return to the site the following day to finish collecting the samples from monitoring well MW-1.
BEA received the results of groundwater monitoring on September 16, 2013. The results
reported all concentrations of fractional EPH and target PAHs as well as fractional VPH and

Characterization standards.
BEA returned to the site again on October 17, 2013 to perform groundwater and sub-slab
vapor monitoring at the Site. Low-flow groundwater sampling was employed to collect
groundwater samples for EPH/PAHs and VPH/BTEX analysis. Results of the October
groundwater sampling event were reported on October 25, 2013. The results reported low
concentrations of aromatic EPH (C 11-C22) impact in monitoring well MW-1 marginally above
the applicable and strictest GW-1, Method 1 Risk Characterization standard. Concentrations of
C19-C36 Aliphatics and C9-C18 Aliphatics were also reported in MW-1 below GW-1 Standards.
The balance of EPH, VPH and target analyte concentrations in MW-1 were reported as non-
detect, wherein the detection limits were less than or equal to the strictest GW-1, Method 1 Risk
Characterization standards. The remainder of monitoring wells reported all EPHNPH and target
analyte concentrations as non-detect (ND). The sum of groundwater analytical results is
presented in Table 7. The significance of these results is discussed in the Risk Characterization
section of this report.

Indoor Air/Soil Vapor Evaluation
BEA traveled to the subject property on August 22, 2013 to review indoor air quality and
to oversee construction of the sub-slab infiltration system. Upon entry to the basement, BEA
reported no detectable petroleum odor with PID readings as ND (<0.1 ppmv).
The sub-slab infiltration system riser was to be constructed of solid 4", schedule 40 PVC
piping and run above grade with a tee-y and capped for possible remedial additive use if
subsequent groundwater sampling results reported concentrations of residual impact. The
infiltration system also serves as a way to measure any residual vapors in soil remaining below
the slab. In consideration of such testing, no PVC glue was to be used, and the riser components
were to be friction-fit, in order to absolve potential interference from the PVC solvent. BEA
related such instructions to the environmental contractor.
BEA returned to the Site on September 5, 2013, to perform groundwater monitoring, as
described above, and to conduct APH testing of soil vapor. Upon arrival at the Site a brass
Vapor-PinTM was installed through the concrete basement floor. Given that the area of
contaminated soil removal had been capped with plastic sheeting and subsequently backfilled
with flowable fill as would restrict the mobility of residual petroleum volatiles, the Vapor-Pin TM
was installed marginally beyond the Zone B area of soil removal in order to evaluate the potential
for soil vapor intrusion (Refer to Site Plan, Appendix D). Prior to such sampling, BEA
performed PID screening throughout the basement of the dwelling and at the sub-slab infiltration
system riser wherein all TOV concentrations were reported as consistent with background (0.0-
0.2 ppmv) and no persistent petroleum odor was noted in the unfinished basement area. BEA
subsequently purged the vapor point with a PID for ten minutes prior to sample collection.
During the purging of the vapor point, no concentrations of organic vapors were reported on the
PID. BEA personnel then collected an APH sample from SVP-1 by way of a summa canister
under vacuum. Laboratory analytical results were reported on September 13, 2013. The soil
vapor testing results associated with the APH testing of SVP-1 reported all carbon range and
target analyte concentrations as significantly less than the applicable Residential Sub-Slab Soil
Vapor Screening Values.
BEA returned to the Site on October 17, 2013, to perform another round of groundwater
monitoring, and to again conduct APH testing of soil vapor. BEA performed PID screening
throughout the basement of the dwelling and at the sub-slab infiltration system riser wherein all
TOV concentrations were again reported as consistent with background (0.0-0.2 ppmv) and no
petroleum odor was noted in the basement area. BEA subsequently purged the vapor point prior
to sample collection. BEA personnel then collected an APH sample from SVP-1 by way of a
summa canister over a ten minute exposure. Laboratory analytical results were reported on
October 25, 2013. Again, the soil vapor testing results associated with the APH testing of SVP-1
reported all carbon range and target analyte concentrations as significantly less than the
applicable Residential Sub-Slab Soil Vapor Screening Values.

RISK CHARACTERIZATION/IMMINENT HAZARDS [Refer to Appendix E]
Soil
As presented,the S-1, S-2 and S-3 (GW-1/GW-2/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 (S-1), inhalation (S-2)
and environmental (S-3) exposures, and in consideration of potential leaching of contaminants to
groundwater (GW-1/GW-2/GW-3). For the purposes of risk characterization, the strictest S-1/S-
2/S-3 (GW-1), Method 1 Risk Characterization standards are initially considered in review of
exposures related to foreseeable future uses and activities at the Site as the most conservative
approach.
As previously noted, all fractional EPH/VPH compounds and target analyte
concentrations in endpoint soils where less than the most stringent S-1/GW-1, Method 1 — Risk
Characterization standards with the exception of this single sidewall area. Under the provisions
of 310 CMR 40.0926, and Exposure Point Concentration (EPC) was developed in review of
exposure risks and regulatory closure objectives. Based on the computed EPC, the averaged 2-
methylnaphthalene concentration remained above than the strictest S-1 (GW-1) threshold [2.7
ppm > 0.7 ppm (S-1/GW-1)]. Such that 2-methynaphthatlene GW-1 standards are strictly

leaching based [Refer to Table 9], further consideration of alternative standards under Method 2
and Method 3 are were considered under the provisions of 310 CMR 40.0983 to 40.0985.
Under Method 2, a preponderance of physical evidence has been developed to evaluate
the presence of any 2-methynaphthalene associated with the historic release of fuel oil in down
gradient monitoring wells. No such groundwater impacts have been reported in the three rounds
of groundwater sampling conducted as supports a finding of No Significant Risk associated with
residual concentrations of 2-methynaphthalene. Additional quarterly groundwater sampling in the
first quarter of 2014 will complete this Method 2 evaluation and qualify such preliminary
findings.

Additionally, the use of the MA DEP Method 3 ShortForms considering both the "worst
case " discrete exposure and EPC, both produced Hazard Index (HI) and Excess Lifetime Cancer
Risk indicating No Significantly Risk as associated with residual soil impacts at the subject Site
following soil removal (Refer to Appendix E). Based on the calculated"worst case" discrete and
EPC considerations, each of the Method 3 Shortform reported chronic and sub chronic hazard
indexes as less than one (<1) and an excess lifetime cancer risk (ELCR) of less than 10E-05

MA DEP Method 3 Residential ShortForm from Worst Case Discrete Exposure
As such, the reported laboratory analytical results under Method 3 Risk Characterization
have demonstrated that the soils along the extent of excavation represent a condition of No
Significant Risk as consistent with the provisions of 310 CMR 40.0993(6). Therefore,
laboratory analysis under Method 2 and Method 3 has demonstrated effective soil remediation
and a condition of No Significant Risk with respect to soils at the Site as will be further
substantiated by additional groundwater sampling and analysis.
Groundwater
As presented, the subject property is mapped within a PDWSA as considers potential
water supply development and ingestion exposure risks. Based on the PDWSA designation for
NOVEMBER 19,2013 IDLEWILD TRUST/BEA13-10550
PAGE 20 OF 23 RELEASE ABATEMENT MEASURE STATUS I,RTN 4-24663
the subject property and surrounding area, as well as the depth to groundwater, the GW-1, GW-2
and GW-3 groundwater categories are applicable to Method 1 Risk Characterization. These
standards were developed to evaluate potential ingestion (GW-1), inhalation (GW-2) and
environmental (GW-3) exposures. For the purposes of risk characterization, the most restrictive
GW-1/GW-2/GW-3, Method 1 - Risk Characterization standards are considered.
In the initial two rounds of groundwater testing, no significant impact to groundwater
relative to the Method 1 standards was noted although C 11 to C22 aromatic concentration were
reported in the up gradient MW-1 monitoring well closest to the former abandoned underground
tank. Following the removal of impacted soils, the most recent groundwater testing has reported
concentrations of fractional EPH in monitoring well MW-1 again with the C11-C22 fraction
reported as above the most stringent GW-1, Method 1 Risk Characterization standards. All other
EPH and target PAH concentrations in MW-1 and all other existing wells were reported as
significantly less than the strictest GW-1 criteria or as non-detect.
Increased aromatic concentrations in MW-1 are suspected as related to its proximity to
soil removal operations and low water levels with high turbidity in the samples. Further seasonal
evaluation of this well as a discreet exposure will be considered. Monitoring wells MW-3 and
MW-4 have been established as downgradient from the release area and within the spatial and
temporal.solute transport pathways. Both monitoring wells MW-3 and MW-4 have reported
concentrations of EPHNPH and all target analytes as non-detect, with the exception of trace
concentrations of Naphthalene in MW-4 during the initial sampling event in August.
In all groundwater analysis conducted to date, concentrations of EPH/VPH compounds
and target analytes have been less than the GW-2 and GW-3, Method 1 Risk Characterization
standards. This data supports a finding of No Significant Risk of organic vapors being released
from groundwater and entering the occupied dwelling creating as an inhalation exposure (GW-2)
nor significant impacts to down gradient environmental resources (GW-3).
The evaluation of practical exposure risks considers that water supply development at the
Site and surrounding area is likely precluded by dense residential development on lots ranging
from 1/4 to 1/2 acre in size, and may be further precluded by possible brackish conditions based on
the-proximity to Nantucket Sound. Furthermore, the Site and surrounding residential properties
are served by the Barnstable Water Company distribution system (PWS) as practically absolving
exposure risks associated with the ingestion of contaminated groundwater. Based on the PWS
service to the subject property and laboratory analytical that has reported all petroleum
hydrocarbon concentrations in groundwater as significantly less than the no Imminent or
Substantial Hazard conditions associated with groundwater are apparent at the present time as to
be further qualified by future testing to document a condition of No Significant Risk for all
foreseeable future use of the property, including as a source of potable water.
Indoor Air
The VPH analysis conducted on end-point soil samples reported some residual volatile
r
NOVEMBER 19,2013 IDLEWILD TRUST/BEA13-10550
PAGE 21 OF 23 RELEASE ABATEMENT MEASURE STATUS I,RTN 4-24663
carbon range and target VOC concentrations as marginally above the strictest S-1 (GW-1/GW-
2/GW-3), Method 1 Risk Characterization standards. The majority of such concentrations in
end-point samples were reported as ND wherein the reporting limits were significantly less than
the most restrictive S-1 (GW-l/GW-2/GW-3), Method 1 Risk Characterization Standards.
However, in accordance with the provisions of 310 CMR 40.0942(1) (d), if one or more VOCs is
present in vadose zone soil adjacent to an occupied structure (i.e. within 6' horizontally from the
wall of the structure or 10' vertically from the basement floor) then the soil has the potential to
result in significant indoor air concentrations of OHM and Method 1 alone cannot be used to
characterize risk at the Site.
Indoor ambient air screening with a calibrated PID has reported background TOV
concentrations (<O.1.ppmv) throughout the basement. Such background TOV concentrations in
the absence of any detectable odor are considered lines of evidence that demonstrated .the
efficacy of the remedial response to remove all contaminated concrete and significantly reduce
the volume of impacted soils. The property is currently unoccupied and kept locked as restricting
access. As such, based on completed response actions, access and ambient air screening, no
Imminent or Substantial Hazards relative to indoor air quality are reported under existing Site
conditions.
To further test potential vapor entry into the dwelling following soil removal associated
with isolated residual soil impacts, a soil vapor probe (SVP-1) was installed through the concrete
basement floor as immediately outside the area of excavation and adjacent to the area of residual
soil impact to qualify soil vapor concentrations under existing conditions in review of potential
for vapor intrusion and inhalation exposures. Two rounds of soil vapor testing were conducted
over the reporting period with the benefit of the heating/hot water system operational. Both soil
vapor analyses reported all APH concentrations as significantly less than the applicable
Residential Sub-Slab Soil Gas Screening in these sampling events. Based on a preponderance of
evidence developed from groundwater sampling relative to GW-2 standards, indoor air and
infiltration system screening and sub-slab soil vapor APH analysis with the removal of
significant soil impacts and impacted flooring, multiple lines of evidence have been developed as
demonstrating that soil vapor entry into the occupied dwelling is not likely. As such, this
information is extrapolated under the "lines of evidence" rationale to support a fording of No
Significant Risk of inhalation exposures at the subject property.
ENVIRONMENTAL MONITORING
Quarterly groundwater monitoring of TPH and/or EPH/VPH plus target analytes in the
existing monitoring wells will be performed in January 2014, in review of potential groundwater
impact and exposure risk characterization. Based on the water level and turbidity of samples,
both filtered and unfiltered samples may be submitted. Subject to these results, groundwater
impacts and exposure risks will be.considered under Method 1 and alternative leaching based
standards will be considered under Method 2 towards consideration of project closure objectives
as represented herein.
NOVEMBER 19,2013 IDLEWILD TRUSTBEAI3-10550
PAGE 22 OF 23 RELEASE ABATEMENT MEASURE STATUS I,RTN 4-24663
Field measurements of groundwater elevations, olfactory and visual observations and the
field-testing of pH, dissolved oxygen, conductivity and temperature will be reported on
Monitoring Well Sampling Logs. Field inspections will be conducted and documented on
"Inspector's Daily Record of Work Progress" reports and remedial response and environmental
assessment work will proceed as consistent with the QA/QC Policies of BEA outlined within
Appendix D. Personal protection and safety standards for BEA are specified in the Site Specific
Health and Safety Plan outlined in Appendix E.
CONCLUSIONS
The RAM served to remove some 60 cubic yards of source material from the qualified
area of significant impact. However, contaminated groundwater marginally above the applicable
and strictest GW-1, Method 1 Risk Characterization MW-I as identified on the Site Plan in was
reported in the most recent round of groundwater sampling and additional temporal data is
necessary to evaluate potential exposures risks under Method 1. Additionally, this additional
temporal data will be used to evaluate the potential leaching of residual soil impacts to
groundwater under Method 2.
An additional quarterly round of groundwater sampling is proposed for January 2014.
Based on the results of the January groundwater sampling event and risk evaluation with the
benefit of this additional data, a RAM Completion Report and Response Action Outcome (RAO)
Statement for project closure will be considered.
The findings of this investigation, as .represented herein, set forth the rationale and
technical,justification for the LSP Opinions offered, as established by the certifications made on
the attached Release Abatement Measure Transmittal Form (BWSC-106) and Remedial
Monitoring Report (BWSC-106A). The LSP Opinions are based on available data and
regulations in effect at the time of this reporting specific to the subject Site.

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

basement floor of the subject dwelling while investigating abandoned fuel lines adjacent to the.
furnace and a separate area of concrete floor staining under the existing aboveground fuel oil
storage tank (AST). Laboratory analysis of representative soil samples from both areas reported
petroleum hydrocarbon impacts greater than RCS-1 Reportable Concentrations in at least 2 yards
of soils as triggering a 120-Day Reportable Condition. Further investigation outside the footprint
of the dwelling found an abandoned underground fuel oil storage tank (UST) off the northeast
corner of the dwelling. Both the UST and the AST were subsequently removed and further
environmental assessment was conducted to qualify appropriate Notification and Remedial
Response actions wherein a threat of groundwater impacts was identified in a mapped Potential
Drinking Water Source (PDWSA — GW-1). Subsequent soil testing and analysis was used to
identify the horizontal and vertical extent of significant soil impacts as between both the interior
and exterior tanks wherein two separate historic releases are indicated. Based on the degree of
weathering and interviews with the surviving heirs of the owner, these releases are suspected as
being more than 10 years old. Groundwater analytical results show low level groundwater
impacts in the vicinity of the former UST (MW-1) but not in the down gradient wells. As such,
low level groundwater impact appears to be limited to the area of release as will continue to be
monitored throughout the RAM investigation.
Additionally, the performance of the RAMP relative to the mitigation of potential
exposure risks will further be evaluated by end point sampling of soils for EPH/VPH analysis.
As dependent upon these results, sub-slab soil vapor sampling may be conducted to evaluate
potential vapor entry into the structure if residual volatiles are reported in the VPH analysis.
Initial groundwater gauging has established a southwesterly groundwater flow direction with
minimal tidal influence. Since monitoring well MW-3 is marginally outside the projected solute
pathway from the release area, an additional monitoring well is proposed to be installed further to
the west as immediately down gradient and adjacent to the release area as representative of any
down gradient impacts or release migration. This well will be sampled within 48 hours of
installation and again quarterly in August and October to evaluate seasonal groundwater
variations.
It is anticipated that soil removal proposed under the RAM can mitigate all significant
exposures risks and any potential critical exposure pathways in support of a Class A, Response
Action Outcome (RAO) as a permanent solution with a highest degree of confidence.
Notwithstanding, no warranty or guarantee of future performance is expressed or implied. It
must be recognized that environmental investigations are inherently limited in the sense that
conclusions are drawn and recommendations developed from the available information obtained
under the context of the regulations and standard of practice at the time of reporting.
This work has and will continue to be conducted under direct LSP oversight in a manner
consistent with the MCP Response Action Performance Standards (RAPS)pursuant to 310 CMR

ENVIRONMENTAL CONDITIONS [Refer to Appendix A]
The subject property at 142 Fifth Avenue is noted on Barnstable Assessor's Map 245 as
Parcel 113 and is located southeast of the intersection of Fifth Ave and Forest Street [Refer to
Figure 1] in the Barnstable Village of West Hyannisport. The UTM coordinates for the Site are
Northing 4610162m and Easting 390093m. The property contains approximately 0.27 acres of
land area and is developed by a one and a half-story residential dwelling and a free-standing
garage. The entire property is upland and relatively flat with approximate elevations ranging
from 20' NGVD in the northern portion of the property to approximately 18' NGVD along the
southern portion.
The surrounding area is heavily developed and in similar use as characterized by seasonal
and year-round residential properties. Access to the subject property and area of release is
unrestricted with high frequency/low intensity of use and children potentially present. The
dwelling occupants and visitors to the property are identified as the primary potential human
receptors to potential inhalation and dermal contact exposures.
Groundwater was encountered at 12-13' below grade surface. Regional groundwater
contours indicate a southwesterly flow direction toward a small unnamed stream and Centerville
Harbor farther west [Refer to Figure 2]. Site-specific groundwater contours were found to be
consistent with local flow direction. Based on groundwater flow direction, the small unnamed
stream represents the primary potential environmental receptor in consideration of Method 1 —
Risk Characterization for potentially receiving impacted groundwater.
Based on the MA DEP Priority Resources Map the subject property is not located within
the Zone II Protective Radius of a Public Water Supply (PWS), nor is it located within the Zone
A protective radius of any surface water reservoir. The Site is shown as a medium-yield
potentially productive aquifer as well as a part of the Sole Source Aquifer designated by the EPA
for all of Cape Cod east of the canal. As such, the Site is defined as within a Potential Drinking
Water Source Area (PDWSA). The Priority Resources Map shows an area of protected open
space southwest of the subject property across Fifth Ave. The Priority Resources,Map also
shows salt and freshwater wetlands to the east, west and south of the Site, as well as NHESP
Estimated Habitat of Rare Wildlife in Wetland Areas.
Based on the PDWSA designation and proximity to groundwater, the. RCGW-1
Reportable Concentrations are applicable per 310 CMR 40.0361, as are the GW-1, GW-2 and
GW-3 Method 1 Risk Characterization standards in accordance with 310 CMR 40.0974. Based
on residential use and Site conditions including frequency/intensity of use and accessibility of
soils, the RCS-1 Reportable Concentrations are applicable per 310 CMR 40.0362, and S-1/S-2/S-
3 (GW-1/GW-2/GW-3), Method 1 — Risk Characterization standards are applicable per 310
CMR 40.0975. These, standards were developed in consideration of potential. ingestion,
inhalation, and environmental exposures, and in review of potential leaching of contaminants to
groundwater. In review of potential future use of the property, the strictest S-1 (GW-1) criteria
are considered under Method 1 Risk Characterization.

BACKGROUND [Refer to Appendix B]
During a home inspection for a pending real estate transaction, the home inspector noted
subsurface copper lines, adjacent to an exterior wall, in the northeastern portion of the basement.
BEA was subsequently contracted by the potential buyer's realtor to investigate the utility of the
copper lines. As such, BEA personnel traveled to the subject property on May 7, 2013 to
investigate the presence of an abandoned UST and to perform hand borings in the area of the
copper lines to determine if a release of fuel oil had occurred. Upon arriving at the property,
BEA personnel probed the ground adjacent to the northeast corner of the dwelling for signs of an
underground tank. A large object, with the approximate dimensions similar to a typical 275-
gallon fuel tank was located approximately 2' below grade in this location. A hole was dug and it
was confirmed that the object was a steel UST. BEA personnel then went to the basement to
perform hand borings to assess subsurface soils. Upon entering the basement, petroleum staining
was observed beneath the existing AST servicing the heating system, representing another
possible release of fuel oil to the subsurface. As such, a series of hand borings were advanced to
investigate subsurface conditions below the basement slab (Refer to Site Plan).
BEA conducted two hand borings (HB-1 and HB-IA) in the area of the AST. HB-1 was
angled beneath the tank to the west, perpendicular to the interior basement wall. HB-lA was
angled beneath the tank to the northwest, towards the corner of two interior basement walls,
where the staining was greatest. Hand boring HB-2 was advanced in the northeastern portion of
the basement adjacent to the subsurface copper lines. The hand borings were advanced with a
J Pp g
stainless steel bucket auger with soil samples collected in 2' intervals. The samples were then
placed in 250-milliliter glass jars with aluminum septa and agitated to develop organic vapors.
The samples were subsequently screened by "jar headspace method" with a PID
[ThermoEnvironmental 580B OVM (10.8 eV lamp)] as consistent with the Interim Soils Policy
(WSC-94-400). PID screening reported elevated organic vapor concentrations < 30 parts per
million by volume (ppmv) in HB-1/HB-lA and < 67 ppmv in HB-2. BEA field preserved soil
samples HB-IA:2-4' and HB-2:4-6' on ice in a cooler for MA Certified laboratory analysis of
risk-based extractable petroleum hydrocarbon (EPH) and target polynuclear aromatic
hydrocarbon(PAH) concentrations.
Laboratory analysis reported concentrations of fractional C9-C18 Aliphatics and CI I-C22
Aromatics greater than the applicable RCS-1 Reportable Concentrations in both soil samples
submitted. As such, laboratory analytical had demonstrated significant petroleum hydrocarbon
impact in more than two yards of soil, and, in the absence of evidence demonstrating a sudden
release, or elevated PID readings (>100. ppmv) in soils, a 120-Day Release Notification
requirement was triggered as the basis of remedial response liability.

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

Groundwater
To further qualify the 120-Day Reportable Condition and the appropriate regulatory
vehicle for Site cleanup, BEA furthered environmental characterization of the subject property on
June 19, 2013 with the advancement of test borings (TBs) for the installation of monitoring wells
(MWs) in review of potential groundwater impacts. BEA personnel directed Jenkins Well
Drilling in the advancement of TB-11, TB-12 and TB-13 towards the installation of monitoring
wells MW-1, MW-2 and MW-3, respectively. Test Boring TB-11 was advanced off the
northeast corner of the dwelling, in the area of the former UST; TB-12 was advanced south of the
dwelling and TB-13 was advanced southwest of the dwelling (Refer to Site Plan). The wells
were finished in water-tight road boxes with locking gripper plugs. Top-of-casing elevations
were also surveyed to a common vertical datum in review of static water level elevations towards
calculating local groundwater flow.
Field headspace screening of soil samples collected from the test borings reported low
concentrations of organic vapors (<2.0) with the exception of TB-11/MW-1 where, in the 17-19'
interval a concentration of 18.2 ppmv was reported. A discrete sample at 19' bgs reported a
concentration of 38.7 ppmv. Representative soil samples TB-11: 11-13', TB-11@19' and TB-
13:11-13'were prepared and forwarded to a certified laboratory for confirmatory EPH with target
PAH analysis. Laboratory analytical results subsequently reported low-level fractional EPH

On June 25, 2013 BEA returned to the subject property to develop and sample the
monitoring well network in review of significant groundwater impacts. Groundwater samples
were collected for EPH/PAH and VPHBTEX laboratory analyses. Laboratory analytical results
reported all EPH/VPH and target analyte concentrations in all wells as non-detect, with the
exception of MW-1 wherein low level fractional EPH was reported below the applicable and
most stringent GW-1, Method 1 Risk Characterization standards.

RISK CHARACTERIZATION/IMMINENT HAZARDS [Refer to Appendix E]
Soil
As presented, the RCS-1 Reportable Concentrations, as well as the S-1, S-2 and S-3
(GW-1/GW-2/GW-3) soils categories are applicable in consideration of Method 1 Risk
Characterization. Laboratory analysis has confirmed the presence of C 11-C22 fractional

aromatics and C9-C18 Aliphatics, as well as 2-methylnaphthalene, as exceeding the RCS-1
Reportable Concentrations as well as the S-1/GW-1 Method 1 —Risk Characterization standards.
As such, remedial response and waste site cleanup activities are prescribed under the RAMP to
absolve potential exposure risks and to meet regulatory closure objective without limitation of
activities or use of the property.
Groundwater
As presented, the RCGW-1 Reportable Concentrations, as well as the GW-1, GW-2 and
GW-3 groundwater categories are applicable in consideration of Method 1 Risk Characterization.
These standards were developed to evaluate potential ingestion (GW-1), inhalation (GW-2) and
environmental (GW-3) exposures. Groundwater sampling and associated laboratory analysis
have reported no significant impacts above GW-1 Standards in any of the on-site monitoring
wells. However, based on groundwater gauging and site-specific groundwater flow calculations
it has been determined that there are no groundwater monitoring wells that are within a
definitively down gradient position. As such, one additional monitoring well is prescribed within
the RAMP.
Indoor Air
Indoor ambient air quality within the living space of the residence was screened during
the initial Site inspection on May 5, 2013 and has been monitored during subsequent Site visits.
The screening has been conducted utilizing a pre-calibrated PID with a 10.6 or 11.8eV lamp.
Each indoor air screening event has reported no detectable petroleum odors and background
TOV concentrations (<O.1 ppmv) in the dwelling basement. No additional testing has been
conducted at this time as the dwelling is currently unoccupied.
Indoor air quality will continue to be monitored duringsubsequent Site inspections for
q Y q P
worker safety. During soil removal operations a vapor barrier will be installed between the
Y g p P
basement and living area with active ventilation provided. As part of the RAM, all impacted
flooring will be removed and replaced inside the dwelling as eliminating interior sources of
organic vapors. Pursuant to the Interim Final Vapor Intrusion Guidance (Policy WSC-11-435),
as well as anticipated revisions to the MCP, Air-phase Petroleum Hydrocarbon (APH) testing of
representative soil vapor beneath the concrete basement slab will supplement the PID screening
towards the development of multiple lines of evidence to evaluate potential vapor intrusion and
inhalation exposure risks, should residual volatile organic compounds be present within the
prescribed setbacks as framed in the provisions of 310 CMR 40.0942(l)(d).
Imminent Hazard Evaluation
Based on the assessment activities conducted to date, which indicate that all significant
fuel oil impacts remain at more than 9' below grade or beneath the footprint of dwelling, at which
time the dwelling has been largely uninhabited, no Imminent or Substantial Hazards have been
identified at the Site. Groundwater monitoring has reported no significant impacts associated
with the subject release, and the most recent indoor air quality screening has reported no TOV
concentrations within the dwelling above the sensitivity of the instrument (<0.1 ppmv).

DULY 19,2013 IDLEWILD TRUST/BEA13-10550
PAGE 11 OF 13 RELEASE ABATEMENT MEASURE PLAN/RTN 4-24663
Monitoring of groundwater, indoor air and soil vapor will continue in review of potential impacts
and risk characterization to evaluate potential hazards towards development of a preponderance
of physical evidence in qualifying exposure risks and demonstrating No Significant Risk.
RELEASE ABATEMENT MEASURE PLAN [Refer to Appendix El
The information from the assessment of current soil and groundwater conditions was used
to develop a remedial strategy for the, excavation of significantly impacted soils from the
identified release area noted on the site plan. This remedial strategy calls for the removal of the
concrete floor and impacted subsurface soils to a depth of up to 6' below the basement floor. It is
anticipated that as much of 60 cubic yards of impacted soil may be generated. Temporary
structural support of the chimney and northeast corner of the subject building will be installed by
a licensed contractor with appropriate permitting. Prior to the beginning of work the furnace will
be removed.
Subsequent to the shoring of the building, the environmental contractor will break up the
basement floor and properly dispose of any and all impacted concrete. The contractor will then
use an excavator to segregate and stockpile clean overburden material adjacent to the exterior
basement walls. Soil removal will then be advanced to depth from the north to the south. Soils
will be transported off site under an approved Bill of Lading for direct loading and transportation
to Aggregate Industries South Dennis asphalt batching facility.
Following the removal of significant soil impact as anticipated in the beginning of August
2013, confirmatory end-point soil samples will be collected for risk-based EPH/VPH analysis, or
for TPH analysis as a cost saving measure wherein field-testing indicates petroleum and volatile
impacts are clearly absent. After field screening has indicated that risk based closure objectives
have been met, a subsurface sub-slab venting/SVE system will be constructed and installed in the
excavated area of release. The venting system will be constructed of 4 x 4"perforated PVC pipe
laterals, as set in washed stone along the bottom-of-hole area. A 4" solid piece of PVC riser will
be plumbed to the lateral components and connected to a wind turbine for the passive venting of
residual volatile petroleum compounds. The venting system will also provide the flexibility to
deliver remedial additives, as may be necessary to mitigate significant residual soil impacts or for
any groundwater treatment.
If residual volatile compounds are reported in the end point samples as within 6'
horizontally and 10' vertically of the basement floor, a soil vapor probe will be installed and
tested for APH. APH analytical results will be compared with the sub-slab screening values set
forth in the Interim Final Vapor Intrusion Guidance document (Policy WSC-11-435). This
testing may be repeated to establish the prescribed "lines of evidence" rationale to evaluate
potential vapor entry into the occupied structure and related inhalation exposures.
The monitoring wells will be sampled quarterly in August and October 2013 following
soil removal. The quarterly groundwater analysis will be used to evaluate any residual petroleum
hydrocarbon impacts to groundwater. The further treatment of soils and/or impacted groundwater
will be evaluated from the results of end-point soil sampling and fiiture quarterly groundwater
assessment. Specifications of potential remedial equipment, operations and maintenance, or use
1 2 -1 JULY 9, 013 IDLEWII,D TRUSTBEAI3 0550
PAGE 12 OF 13 RELEASE ABATEMENT MEASURE PLAN/RTN 4-24663
of any remedial additives will be represented as a modification of the RAM, if applicable, to be
reported in subsequent RAM Status (RAMS) reports. All such work will be compiled on
"Inspector's Daily Record of Work Progress"reports and documented in a RAM Status Report or
RAM Completion Report to be submitted within 120 days of this filing.
CONCLUSIONS
The Release Abatement Measure Plan, represented by this filing, proposes the excavation
and disposal of up to 30 cubic yards of significantly impacted soils from the release area
identified on the Site Plan in Appendix A.
Under the RAM Plan, BEA will direct the segregation of clean overburden material
surrounding the dwelling to accommodate the excavation and disposal of contaminated soils.
Field PID screening and Dexsil testing will be used by BEA personnel to provide technical
assistance and direct excavation operations. A subsurface venting system will be constructed and
set in washed stone aggregate prior to final restoration for venting of residual petroleum
hydrocarbons, and/or future remedial additive applications if necessary. This work is intended to
eliminate the contaminant source and associated exposure risks to identified human and
environmental receptors towards achieving a condition of No Significant Risk in support of a
permanent solution.
This work is scheduled to begin in the beginning of August 2013. A RAM Status Report
or RAM Completion Report with Response Action Outcome (RAO) will be submitted within
120 days of this filing. Any subsequent RAM Status Reports will be filed every six months
thereafter until a preponderance of physical evidence supports a condition of "No Significant
Risk" and RAO objectives are met as supporting an RAM Completion Report.
The findings of this investigation, as represented herein, set forth the rationale and
technical justification for the LSP Opinions offered, as established by the certifications made on
the attached Release Abatement Measure Transmittal Form(BWSC-106). The LSP Opinions are
based on available data and regulations in effect at the time of this reporting specific to the
subject Site.
