Dear Ms. McLaughlin,
BENNETT ENVIRONMENTAL ASSOCIATES, INC. (hereinafter referred to as`BEA")
has prepared the following Release Abatement Measure Completion (RAMC) with Class A-2
Response Action Outcome (RAO) and Supporting Documentation as a summary of release
discovery, environmental assessment and remedial action conducted at the above-referenced
property as associated with a historic fuel oil release and the identification of a 120-Day
condition. Additionally, the RAMC / RAO report summarizes the completed remedial response
actions undertaken to mitigate potential human exposures and environmental impacts in
accordance with the provisions of 310 CMR 40.0440 where there existed a threat of groundwater
impact. Initial environmental assessment activities were conducted to qualify the magnitude and
extent of significant soil impact associated with a previously unidentified historic release of an
unknown quantity of#2 fuel oil in an earthen crawl space beneath the southern portion of the
dwelling.
The area of the former tank was clearly visible within the crawl space that underlies the
former porch area in the southwest portion of the residence. Soil had been removed within the
crawl space to allow for sufficient headroom to locate the tank and a concrete pad was poured to
support the legs of the vessel. An initial investigation determined that 1 to 2 feet of soil along the
perimeter of the concrete slab were impacted. Fuel oil had apparently flowed over the slab to the
edge of the slab and entered into the underlying soils. In subsequent investigation, the vertical
extent of soil contamination had been determined to extend at least to 16' below grade surface
(bgs) at the angled HB-5 sampling location and, as such, represented a threat of groundwater
impact as precluded a Limited Removal Action (LRA), wherein environmental monitoring

beyond soil removal was deemed appropriate and necessary in review of potential exposure risks.
As such, a Release Abatement Measure (RAM) Plan, with Release Notification, dated October
24, 2008 was submitted for soil removal operations and construction of a sub-slab venting system
to mitigate potential exposure risks and facilitate any potential future treatment of residually
impacted soils. An Environmental Monitoring program was further prescribed with end point
soil sampling, testing of monitoring wells and Level 1 screening of ambient air quality in review
of cleanup performance and exposure risks towards a Class A, Response Action Outcome (RAO)
objective.
The Release Abatement Measure was subsequently implemented wherein some 22 tons
(15 cubic yards) of fuel oil contaminated soils were removed from an approximate 8'x 6'x 4' (D)
[10' bgs] area. End-point sampling of sidewall and bottom-of-hole (BOH) areas reported
petroleum hydrocarbon concentrations (VPH/EPH) in the discrete areas as below the most
stringent S-1/GW-3, Method 1 — Risk Characterizations standards. The re-sampling of the
previously installed and representative downgradient groundwater monitoring wells reported
petroleum hydrocarbon concentrations (TPH) concentrations as below the applicable GW-3,
Method 1 — Risk Characterization thresholds. Additionally, the dwelling and the sub-slab
venting system was monitored for residual vapors wherein measured total organic vapors (TOV)
concentrations were less than the Method 2 Risk Standards established in the MA DEP Policy
WSC-02-411, Implementation of MA DEP VPHIEPH Approach. As such, the environmental
assessment of soil, groundwater and ambient air associated with the RAM indicates a condition
of No Significant Risk for any ingestion, inhalation or dermal contact exposures to identify
human receptors and the environment in support of a Class A-2, RAO as a permanent solution
for project closure.
The information herein serves as a summary of the remedial response actions and
environmental assessment conducted as associated with the RAM Plan as an addendum to, an
essential element of, the public record. The environmental data herein has been reviewed and
validated and potential exposure risks evaluated under Method 1, Method 2 and Method 3 risk
considerations as the technical rationale and justification for the LSP Opinions presented to
document regulatory compliance and project closure under the provisions of the MA
Contingency Plan, (MCP) 310 CMR 40.0446 and 40.1035. This work has been 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-106 Transmittal Form.
ENVIRONMENTAL CONDITIONS [Refer to Appendix A]
The subject property at 293 Sea Street is noted on the Town of Barnstable Assessor's
Map 306 as Parcel 78 and is located along the northwest corner of the Sea Street/Stetson Street
DECEMBER 19,2008 FUCCILLOBEA08-10044
PAGE 3 OF 16 RAMC w/CLASS A-2 RAO RTN 4-21596
intersection [Refer to Figure 1]. The residentially zoned property contains approximately 0.3
acres of land area and is developed by a two-story residential style building constructed in
1900+/-. This building has historically and is currently being used as a private, single-family
residence. The surrounding area is developed in similar use, as characterized by residential
properties. Access to the subject property is unrestricted with high frequency/high intensity of
use and children potentially present. Access to the area of release, however, as within the crawl
space of the subject building and is restricted with low frequency/low intensity of use with
children potentially present as infrequent visitors. Residents of the dwelling are identified as the
primary potential human receptors to any ingestion, inhalation or dermal contact exposures.
Monitoring well installation, conducted September 25, 2008, indicated that groundwater
exists at + 25' bgs. Regional groundwater contours indicate a southerly flow direction towards
Hyannis Harbor (0.5 mi south) and Lewis Bay (0.75 mi southeast). Static water level
measurements conducted on September 25 (low tide), September 30 (high tide), October 28 (full
moon/ ebb tide) and November 19 (flow tide) indicates significant tidal influence from westerly
towards Stewart's Creek to southwesterly towards Hyannis Harbor + 0.5 miles to the south. As
such, Stewarts Creek and the associated wetlands and also Hyannis Harbor are identified as the
potential environmental receptors.
According to the MA DEP BWSC GIS mapping program, the subject property is located
within a medium yield, non-potential drinking water source area (NPDWSA) as attributed to
housing density in an urbanized area. The property does not fall within the Zone II Protective
Radius of any Public Water Supply (PWS), nor is it located within the Zone A protective radius
of any surface water reservoir. No private wells are known to exist within 500' of the Site
wherein the area is serviced extensively by the Town of Barnstable municipal water supply and
distribution system. Based on this mapping and field observations, the GW-3 groundwater
category is applicable under Method 1 —Risk Characterization, per 310 CMR 40.0974. Based on
Site conditions relative to frequency/intensity of use and accessibility of soils, wherein the release
area is within the crawl space of the basement of the subject building, the S-2 and S-3 (GW-3)
Method 1 —Risk Characterization standards are applicable to soil impact in accordance with the
provisions of 310 CMR 40.0975. In review of all foreseeable future uses and activities at the
Site, the most restrictive S-1 (GW-3), Method 1 — Risk Characterization standards are
considered. These standards were developed in consideration of potential ingestion, inhalation
and environmental/dermal contact exposures and in review of potential leaching of contaminants
to groundwater.
BACKGROUND [Refer to Appendix A]
BEA received a phone call from the property owners during the weekend of August
23/24, 200& The homeowners were in the process of selling the house and a home inspector
detected the presence of a fuel oil odor in the crawl space area. A visual inspection evidenced
what appeared to be an excavation with an adjacent pile of dirt that apparently was cast from the
excavation. No public records of any permits relative to the former existence or removal of a
fuel tank for the property could be located. Additionally, forensic evaluation of the degree and
amount of hydrocarbon degradation indicated that the fuel oil residuals were significantly
DECEMBER 19,2008 FUCCILLOBEA08-10044
PAGE 4 OF 16 RAMC w/CLASS A-2 RAO RTN 4-21596
degraded as indicating that the release had occurred at least 10 years earlier and prior to the
current owner's purchase of the property. At the time the current owners took possession of the
property in 2001, the domestic heating already had been converted to natural gas and the storage
tank had been removed.
BEA contracted with the homeowners, who live out of state, to meet with their realtor,
photo-document conditions within the crawl space area and conduct limited soil sampling and
analysis to qualify environmental impacts and determine if release notification and/or remedial
response liability was present under the provisions of 310 CMR 40.0000. These initial
preliminary response actions and assessment activities are summarized in the following section
of this report. The reader should review the written RAM Plan for additional details.
ENVIRONMENTAL ASSESSMENT [Refer to Appendix A]
Soil
BEA conducted the initial soil sampling on August 27, 2008 in the earthen crawl space
under the addition on the south side of the dwelling. Analytical results from HB-1 and HB-2
samples reported total petroleum hydrocarbon (TPH) concentrations of 12,000 parts per million
(ppm) and 7,800 ppm respectively in the surficial soils under the former tank. These
concentrations are significantly above the applicable RCS-1 Reportable Concentration threshold
of 1,000 mg/kg and the applicable S-3/GW-3, Method 1 — Risk Characterization standard of
5,000 mg/kg. This testing further indicated that more than 2 yards of soil had been impacted
above the aforementioned standards.
Wherein a 120-Day Reportable Condition was identified, BEA returned to the property on
September 8, 2008 to collect additional sidewall samples and advance additional hand borings in
the areas at the perimeter of the buried concrete slab, towards defining the extent of significant
soil impacts and potential for groundwater impacts. BEA collected sidewall samples from the
dug out area of the crawl space for field testing and advanced hand borings adjacent to the area of
documented impacts. Hand borings HB-3 and HB-4 were advanced to 6' and 8' feet below grade
surface (bgs) off of the east and west ends of the exposed concrete slab, respectively. Borings at
these locations were limited by available headroom and the friable nature of soils underlying the
dwelling. Field screening of soil samples from HB-3 and HB-4 reported low-level total organic
volatiles (TOV)concentrations from zero to 2.4 parts per million(ppmv).
Hand boring, HB-5, was advanced to a depth of 16 feet bgs between the paved driveway
and building footing, immediately adjacent to the crawl space release area [Refer to attached site
plan]. This hand boring was angled to intercept soils under the release area. Soils at the HB-5
location consisted of loose, medium to coarse grain sands with nominal cohesion. Field
screening of soil samples from HB-5 reported moderate TOV concentrations from zero to 44
ppmv and increasing with depth. Groundwater was not encountered at the HB-5 location as
projected at 25' below existing grade.
DECEMBER 19,2008 FUCCILLOBEA08-10044
PAGE 5 OF 16 RAMC w/CLASS A-2 RAO RTN 4-21596
Soil samples HB-5: 8'-10' and 12'-14' were submitted for MA Certified laboratory
analysis of TPH and the 15'-16' interval sample was submitted for laboratory analysis of
extractable/volatile petroleum hydrocarbons (EPH/VPH). Analytical results were received on
September 11, 2008. The analyses reported TPH concentrations in the HB-5: 8-10' sample as
1,900 parts per million (ppm) and in the HB-5: 12-14' sample as 1,100 ppm. However, the
"worst case", TOV-biased HB-5: 15-16' sample reported EPH and VPH carbon range and target
analyte concentrations as less than the applicable S-3/GW-3, and most stringent S-1/GW-3,
Method 1 —Risk Characterization standards. As such, the TPH samples were re-analyzed for the
risk-based EPH/VPH analysis in order to quantify the magnitude of impact in the consideration
of risk as critical to the formulation of a remedial strategy. These analytical results were received
the afternoon of September 16, 2008 and reported all fractional VPH/EPH standards and target
analytes at concentrations less than the applicable S-3/GW-3 and most restrictive S-1/GW-3,
Method 1 — Risk Characterization "cleanup" standards. These results indicated that the
excavation of soils to 8' bgs in the area of release should meet closure objectives. As such, a+
4-6' excavation to a depth of 8-10' bgs was proposed within the RAMP as approximately 15
yards of significantly contaminated soil.
Groundwater
Although the soil testing indicated that the S-1/GW-3 standards were met in soil samples
below 8' bgs, residual soil impacts extended to depth as threatening potential groundwater
impact. As such, the monitoring well were prescribed and installed for determination of site-
specific groundwater flow, aquifer characteristics and groundwater quality. BEA returned to the
Site on September 25, 2008 to direct test borings and the installation of monitoring wells as
performed by Jenkins Well Drilling of Brewster, MA [Refer to Site Plan—Appendix A].
BEA personnel returned to the site on September 30, 2008 to re-gauge purge and
subsequently sample all three monitoring wells for laboratory analysis of total petroleum
hydrocarbons (TPH) as a cost savings measure to serve as an indicator for any environmental
impact. The groundwater samples were collected in appropriately preserved laboratory
containers and field preserved on ice. A series of rising-head slug tests were performed at
monitoring well MW-3 to qualify hydraulic conductivity in review of aquifer characteristics and
solute fate and transport mechanisms. The Geraghty and Miller AQTESOLV program was
employed to interpret the results of the slug tests wherein a hydraulic conductivity of 38.31 feet
per day. Based on the calculated hydraulic conductivity and hydraulic gradients reported along
specific groundwater flow vectors from MW-1 to MW-2 and MW-1 to MW-3, the groundwater
velocity from the release area was reported as 0.12 ft/day. Well gauging and static water level
measurements demonstrated tidal influence on groundwater flow as westerly to south westerly
beneath the site as confirming MW-2 in a downgradient location and as representative of
potential downgradient groundwater impacts. Groundwater samples collected from all
monitoring well locations reported TPH concentrations as BRL with reporting limits less than the
applicable GW-3,Method 1 —Risk Characterization standards.

The release discovery was framed within the Release Notification Transmittal Form filed
with the MA DEP on October 20, 2008. On the MA DEP assignment of a Release Tracking
Number(RTN 4-21596) a Bill of Lading was prepared and incorporated into a written RAM Plan
as filed with the MA DEP on October 24, 2008.
RELEASE ABATEMENT MEASURE [Refer to Appendices B and C]
Subsequent to discussions with the property owner and the selected contractor (N. P.
Christiani —NPC) regarding the Scope of Work and construction logistics, BEA returned to the
Site on Thursday October 23, 2008 to review project status and deliver the executed Bill of
Lading (BWSC-012A, B, C) and Aggregate Industries Soil Recycling Submittal to the contractor.
Upon arrival BEA personnel noted that the joists supporting the first floor of the residence had
been supported with two steel beams and cribbing extending from the driveway area adjacent to
the release area to the interior of the main basement area. BEA and NPC personnel discussed the
proposed area of contaminated soil removal and associated activities which were coordinated to
commence the following Monday, October 27 following the submittal of the RAMP.
Excavation operations began the morning of the 27fl' with a brief "tailgate" health and
safety meeting followed by the commencement of soil vactoring of all soil cast from the former
tank area onto the native grade of the crawlspace. Once all of this former tank related soil was
removed, soil removal continued laterally to the final dimension of the excavation and vertically
down to the concrete slab which supported the former tank (± 6' bgs) in the tank grave resulting
in an approximate 8' x 6' x 6' bgs excavation as originally planned. The concrete slab was easily
broken with a sledge hammer and removed along with additional soil down to the 6' to7' bgs
horizon across the entire excavation bottom. BEA personnel collected end-point soil samples
representative of the excavation sidewalls via hand auger. Additional bottom of hole samples
were collected at the limits of the excavation and field screened in review of remedial
performance. Field screening of these end-point soil samples reported low—moderate headspace
TOV concentrations. All soil samples were also field screened via a Dexsil "Petro-flag" TPH
analyzer. The tabulated field screening results for the initial sampling is presented below.

Based upon the initial field screening results (TOVs = 23ppm, TPH = 1600ppm), the
north sidewall was extended approximately 1.5 feet and retested. Based on these subsequent
results (NSW 6-10'-x; PID=6.Oppm / TPH=102ppm), the lateral extents of the excavation had
been established and soil samples placed in the appropriate containers and preserved and ices as
necessary for laboratory analysis. BEA personnel conducted a hand boring (HB-6; 7'-9')
centrally in the excavation to assess the vertical BOH objective. A composite sample was field
DECEMBER 19,2008 FUCCILLOBEA08-10044
PAGE 7 OF 16 RAMC w/CLASS A-2 RAO RTN 4-21596
screened with the above results indicating fuel residuals still in excess of the strictest S-1/GW-1,
Method 1 —Risk Characterization thresholds. Additionally, this 7' to 9' bgs interval consisted of
very loose "sugar' sand which was determined to necessitate the installation of shoring. NPC
began the installation of shoring along the north and south sidewalls. The shoring was advanced
in a narrow trench created by the soil vactor along the sidewalls in front of the vertically installed
2"x10" pressure treated lumber in anticipation of extending the excavation to 10' bgs. At this
point the soil vactor departed the site to meet the Aggregate facility's closing time. It was later
verified that the initial vactor load contained 12.41 tons of soil [Refer to BOL — Appendix C].
BEA departed the site leaving instructions to be contacted the next day when the shoring was
completed and the excavation reached 9' bgs.
Contractor personnel returned to the subject property the next day October 28, 2008 to
complete soil removal as specified. Vactoring advanced the excavation within the shoring box to
approximately 9'. BEA returned to the Site late in the morning and soil vactoring continued
vertically until the intended 10' bgs depth had been reached at which point representative,
confirmatory bottom soil samples were collected. The bottom soil sample consisted of 6-8 equal
aliquots of soil from across final grade of the excavation as placed in the appropriate containers
and preserved and ices as appropriate for laboratory analysis. At this point the soil vactor again
departed the site to meet the Aggregate facility's closing time. It was later verified that the final
vactor load contained 9.66.41 tons of soil [Refer to BOL—Appendix C].
BEA personnel advanced a hand boring (HB-7) between the center BOH and the exterior
HB-5 and collected composite samples in 2' intervals for field screening is further consideration
of residual soil impacts to depth. Field screening of these and BOH end-point soil samples
reported low — moderate headspace TOV concentrations. All soil samples were also field
screened via a Dexsil "Petro-flag" TPH analyzer. Field TPH screening of these end-point soil
samples reported low — moderate TPH concentrations. These tabulated field-screening results
are presented below.

Field TPH screening of the soil samples collected reported TPH concentrations
significantly less than the most restrictive S-1 (GW-3), Method 1 — Risk Characterization
standard of 1,000 ppm. As such, field-testing had indicated the effective removal of significant
soil impacts. Ambient air monitoring within the work zone at the extent of excavation reported
TOV concentrations as BDL(<O.1 ppmv).
All confirmatory samples were submitted to be laboratory analyzed via MADEP EPH
methodology. Additionally, the "worst case" excavation BOH and HB-7 samples were analyzed
via the MA DEP VPH methodology. Laboratory analytical results for the east, south and west
confirmatory sidewall soil samples reported all EPH/PAH concentrations as BRL wherein the
reporting limits were less than or equal to the most restrictive S-1/GW-3, Method 1 — Risk

BEA personnel returned to the Site on November 19, 2008 to gauge and sample the
monitoring wells, install and screen a sub-slab soil gas sampling probe and perform indoor
ambient air monitoring and modified Level 1 Soil Gas Screening at the sub-slab venting system
riser in review of risk characterization. All of these potential exposure points reported a TOV
concentration of BDL (<0.1 ppmv) which is inherently less than the strictest response standard
(ethylbenzene) for the instrument used (PID with 11.6 eV lamp) reported in Table 4-9 of the MA
DEP Policy #WSC-02-411, Implementation of the MA DEP VPHIEPH Approach. BEA
personnel returned to the Site several times over the remainder of the reporting period to conduct
ambient air monitoring and Level 1 Soil Gas Screening via the sub-slab venting system and soil
vapor probe. The maximum TOV reading of 0.2 ppmv was recorded in these supplemental
inspections as significantly less than the strictest response standard (ethylbenzene) for the
instrument used (PID with 11.6 eV lamp) reported in Table 4-9 of the EPH/VPH policy (#WSC-
02-411). As such, modified Level 1 Soil Gas Screening has demonstrated that degradation of
indoor air quality due to low-level residual impact in soil is unlikely, in accordance with Table 4-
9 of the EPH/VPH policy. The sum of Level 1 Soil Gas Screening and indoor ambient air
monitoring is presented in Table V. The significance of these results is further discussed in the
Risk Characterization section of this report.

All three monitoring wells were sampled a second time for laboratory analysis of total
petroleum hydrocarbons (TPH) as a cost savings measure to serve as an indicator for any
groundwater impacts. The groundwater samples were collected in appropriately preserved
laboratory containers and field preserved on ice. The analytical results for all three monitoring
on each of the sampling rounds were BRL wherein the reporting limit concentration is
significantly lower than the applicable GW-3, Method 1, Risk Characterization standard. The
significance of the end point soil sampling, groundwater analysis and post excavation ambient air
quality screening relative to potential exposures and risk is presented in the following section of
this report.
RISK CHARACTERIZATION [Refer to Appendix D]
Soil
As presented, the S-2 and S-3 (GW-3) soil categories are applicable to potentially
accessible and isolated soils within the defined area of release under current Site conditions in
consideration of exposures under Method 1 - Risk Characterization, as consistent with the
DECEMBER 19,2008 FUCCILLOBEA08-10044
PAGE 11 OF 16 RAMC w/CLASS A-2 RAO RTN 4-21596
provisions of 310 CMR 40.0933. For the purposes of risk characterization in consideration of
foreseeable future uses, the most restrictive S-1 (GW-3), Method 1 - Risk Characterization
standards are further considered relative to potential ingestion, inhalation and dermal contact
exposure risks to identified human and environmental receptors. Laboratory testing of end point
soil samples in the sidewall (SW) and Bottom of Hole (BOH) areas by risk-based, fractional
EPHNPH data has reported concentrations of fractional aromatic/aliphatic compounds and target
analytes in each discrete sidewall and BOH areas are significantly below the applicable S-2 and
S-3/GW-3, and most stringent S-1/GW-3, Method 1 — Risk Characterization standards.
Furthermore, this testing has been considered to qualify the vertical extent of significant soil
impact and threat of groundwater impact wherein the most restrictive soil samples below the
extent of excavation also report fractional compounds and target analytes as significantly below
the S-1/GW-3, Method 1 —Risk Characterization standards. The S-1 standards are developed in
consideration of ingestion, inhalation and dermal contact exposures and as a measure of potential
leaching to groundwater. As such, the data indicates a condition of No Significant Risk for
potential exposures to identified human and environmental receptors associated with remaining
isolated residual soil impacts.
As a conservative measure, averaged low level petroleum hydrocarbon concentrations
were use to calculated an EPC from the reported EPH/PAH and VPH/BTEX concentrations
reported along the extent of contaminated soil removal. These averaged concentrations were
applied to the Residential Short Form/Exposure Scenario to qualify risk under Method 3 — Risk
Characterization, as presented in Appendix C. The Residential Short Form computed the
"Subchronic Hazard Index" as 1 E-02 and the "Chronic Hazard Index" as 6E-02. Wherein all of
the calculated values for were reported as significantly less than 1.0, the Residential Short
Form/Exposure Scenario supports a finding No Significant Risk relative to potential exposures to
human and environmental receptors as consistent with the Method 1 — Risk Characterization of
soils.
Groundwater
As noted above,the GW-3 groundwater category is applicable in consideration of Method
1 - Risk Characterization at the Site as based on the NPDWA designation on the current Mass
GIS Mapping (21E Overlay) wherein ingestion exposures are not considered as a foreseeable
exposure risk. Furthermore, based on the depth of groundwater, inhalation exposures from
impacted groundwater also not considered a foreseeable exposure risk. The GW-3 standards are
developed in consideration of any significant environmental impacts and potential dermal
contacts associated with impacted groundwater. The results of two (2) rounds of groundwater
testing for all monitoring well locations has reported no groundwater impact wherein TPH
concentrations are reported as BRL and the reporting limit concentrations are significantly less
than the GW-3, Method 1 —Risk Characterization standards. Site-specific groundwater flow and
solute transport modeling show that MW-2 and MW-3 are in downgradient locations.
Monitoring well MW-2 is adjacent and immediately downgradient of the projected solute
pathways as representative of groundwater impacts associated with a historic release of fuel oil
more than 10 years prior to this filing. As such, groundwater conditions characterized at the Site
represent a condition of No Significant Risk as associated with potential inhalation and dermal
DECEMBER 19,2008 FUCCILLOBEA08-10044
PAGE 12 OF 16 RAMC w/CLASS A-2 RAO RTN 4-21596
contact to humans and environmental impacts to downgradient resources. It is noted that TPH
concentrations indicate no impact to groundwater as meeting even the most stringent GW-1,
Method 1 —Risk Characterization standards.
Indoor Air
No evidence of petroleum has been reported with the basement or living areas of the
subject dwelling as based on olfactory observations and TOV screening of the dwelling interior.
Indoor air quality screening within the basement routinely conducted with a PID [Thermo
Environmental 580 B PID,11.8 eV lamp, calibrated to a benzene standard with isobutylene gas]
has consistently reported no detectable response (BDL <0.1 ppmv) as indicating no measurable
organic vapors. Subsequent to soil removal operations, low-level residual volatile (VPH —
carbon range aliphatics, aromatics) impact was reported at the BOH (10'bgs) and HB-7 (10-15')
within the former excavation. Based on the concentrations and locations of the residual volatile
impact beneath + 6' of flowable fill with a sub-slab venting to the exterior of the dwelling,
intuitive reasoning would indicate that impacts to indoor air quality are unlikely.
In order to further evaluate and qualify any potential for adverse impacts to indoor air
quality, BEA conducted TOV monitoring at the sub-slab venting system riser as consistent with
Method 2, Level 1 — Soil Gas Screening. The TOV concentrations were consistently reported as
0.2 ppmv as consistent with background and less than the strictest response standard
(ethylbenzene) and applicable response standards (C9-C12 aliphatics, C9-C10 aromatics) for the
instrument used [PID, 11.8 eV lamp, calibrated to a benzene standard with isobutylene gas], as
reported in"Table 4-9: Soil Gas PID/FID Screening Levels for Evaluating Indoor Air Impacts"of
the Implementation of the MA DEP UIFEPHApproach (Policy#WSC-02-411, 10/31/02). This
monitoring of the sub-slab vent was further substantiated relative to the potential impact to
indoor air via the installation of a sub-slab, soil vapor monitoring probe in accordance with
MADEP Indoor Air SOP August 2007 guidance document with the results reported as less than
the detectable limit of the instrument (<0.1 ppmv). Based on the results of the TOV monitoring
via multiple evaluation technologies, impacts to indoor air are not likely, in accordance with the
provisions of Section 4.3.1.1 of the above referenced policy. As such, TOV testing under
Method 2, have demonstrated no degradation of indoor air quality within the subject building in
support of a finding of No Significant Risk associated with indoor air quality and potential
inhalation exposures at the subject Site.
Imminent and Substantial Hazard Evaluation
As stated, all significantly impacted soils have been removed from the area impacted by
the historic release. Laboratory analytical data for confirmatory soil samples collected from the
extent of excavation reported all petroleum hydrocarbon concentrations as below the applicable
S-1/GW-3 Method 1 — Risk Characterization standards as supporting a condition of No
Significant Risk relative to soils. No groundwater impact has been documented by representative
monitor well sampling and analysis as documenting No Significant Risk associated with
groundwater. Additionally, ambient air quality screening by Level 1 — Soil Gas Screening
methods within the dwelling has established and a condition of No Significant Risk associated
DECEMBER 19,2008 FUCCILLOBEA08-10044
PAGE 13 OF 16 RAMC w/CLASS A-2 RAO RTN 4-21596
with ambient air quality. Wherein a condition of No Significant Risk is established for potential
inhalation, ingestion and dermal contact is soil, groundwater and air medium for all foreseeable
future activities and use of the property, there are no conditions of Imminent or Substantial
Hazard.
DATA USABILITY ASSESSMENT & REPRESENTATIVENESS EVALUATION
The following presents a discussion of the Site information used to support the RAO as
required by 310 CMR 40.1056(2)(k) and incorporating the guidance provided in MA DEP Policy
WSC-07-350. It provides an evaluation and demonstration of the adequacy of the spatial and
temporal data sets used to support the RAO and makes conclusions on the accuracy, precision
and sensitivity of the data used.
Conceptual Site Model
An unknown volume of#2 heating oil was historically released from a former fuel oil
storage tank that was removed prior to occupancy by the current owner. This release was
discovered during a home inspection as part of a real estate transfer. The fuel oil had apparently
been released to the natural ground surface over a concrete slab beneath the former tank and
flowed off of the pad infiltrating into underlying soils. The fuel oil mobilized vertically as
impacting underlying soils to a depth of approximately ± 16' bgs. Contaminated soils were
excavated from the area of release and transported directly to a licensed asphalt batch facility.
Based on field screening and laboratory analytical data, wherein non detect and low level
petroleum concentrations in soil are compliance with the site specific Method 1 cleanup
standards were reported and no groundwater impact as a result of the subject release is apparent
based upon the analytical results from successive sampling and analytical evolutions, a condition
of No Significant Risk exists at the Site.
Field Screening
PID screening and observations were used to qualify significant impact in soils and to
make informed dynamic decisions in the field in advance of submitting samples for MA Certified
analyses. In some cases, Dexsil Petroflag testing was conducted to qualify TPH concentration in
the field. Samples with higher levels of odor or PID screening results are assumed to be more
contaminated than those samples with lower levels. Comparison of visual, PID and observations
with limited analytical data indicates the screening data roughly correlates with the analytical
data.
Sampling Locations
Hand boring locations for environmental assessment of petroleum hydrocarbon
concentrations in soils were selected as based on apparent preferential pathways beneath the
crawlspace as would most likely result in impact to underlying soils. Based on the magnitude of
significant impact and the hand boring locations, an approximate 8' x 6' x 4'(6-10'bgsD) area of
impact was qualified as the target of prescribed soil removal operations. Field PID and TPH
DECEMBER 19,2008 FUCCILLOBEA08-10044
PAGE 14 OF 16 RAMC w/CLASS A-2 RAO RTN 4-21596
screening was used to qualify the extent of contaminated soil removal. Six soil samples were
collected for analyses from the extent of soil removal as above groundwater. Field duplicates or
trip blanks were not collected or considered necessary because the disposal Site was small and
QA/QC protocols were employed and documented. After collection, the samples were kept
within a cooler with ice and subsequently within a refrigerator pending shipment to the
laboratory under a properly executed chain-of-custody.
Temporal Data
Multiple evolutions of monitoring well sampling at times well in excess of the calculated
time of solute travel since the historic release indicate that the fuel oil release did not impact the
aquifer. Laboratory analytical data, soil gas screening and Method I/Method 2 — Risk
Characterization indicate that future indoor air quality will not be impacted as a result of low-
level residual impact along the extent of excavation.
Field Completeness
The analytical data set is complete. Data from the four sidewalls and the bottom-of-hole
as well as extended vertically to the HB-7 location was obtained as representing the extent of
significant impact and the limits of contaminated soil removal. The complete data set supports
the RAO wherein all QA/QC thresholds and Presumptive Certainty requirements were met.
Data Inconsistency
No inconsistent data was identified. Visual observations, odors and field screening were
generally well correlated. No inconsistency was identified between the field screening of end-
point soil samples and their respective laboratory analyses.
Data Not Used
The complete analytical data set associated with confirmatory end-point soil samples was
used to support the RAO as representative of Site and environmental conditions subsequent to
the excavation of significantly contaminated soils. Analytical data associated with soil
assessment, as representative of the identified impact, was used for disposal characterization.
Field screening of significantly impacted soil samples collected during environmental assessment
was used to select appropriate soil samples for laboratory analysis in review of remedial response
actions and risk characterization.
The complete analytical data set associated with groundwater sampling was also
incorporated herein to support the RAO as representative of Site and environmental conditions
subsequent to the excavation of significantly contaminated soils.

PAGE 15 OF 16 RAMC w/CLASS A-2 RAO RTN 4-21596
Data Usability
Laboratory analytical results associated with confirmatory, end-point soil samples and
groundwater samples were reviewed under the current REDUA policy WSC-07-350 for
reliability and usability. The methods utilized (PID soil screening, Dexsil, EPH/VPH and TPH)
all respond to the contaminants of concern identified in the release and are appropriate for a
release of#2 fuel oil. Based on the Representativeness Evaluation, the analytical data quality of
all endpoint soil samples and groundwater samples have been reviewed and evaluated. The
analytical data provided in support of this RAO have met the method quality control
requirements and performance standards for "Presumptive Certainty" as described in CAM VII
A, Section 2.0 (a), (b), (c), and (d) or have been evaluated as comparable to CAM requirements.
The validity and defensibility of the analytical data used to support the findings of the RAO for
this Site with respect to accuracy, precision and completeness pursuant to 310 CMR
40.1056(2)(k) have therefore been satisfied. It has been determined that the Site data is
sufficiently representative of actual Site conditions and may be used to support this Class A-2
RAO.
CONCLUSIONS
Excavation activities have resulted in the removal of all significantly impacted soils from
the crawlspace area to a depth of +6' below the basement floor (10' bgs). Environmental
assessment and monitoring have been used to develop a preponderance of physical evidence
wherein No Significant Risk is associated with low-level residual soil impact and documented
lack of impact to site groundwater and ambient air within the developed Conceptual Site Model
in support of a condition of no significant risk. Method 1, Method 2 and Method 3 Risk
Characterization have been evaluated within the Conceptual Site Model to qualify the condition
of No Significant Risk as associated with all potential media exposures to identified human and
environmental receptors. As such, a Class A-2 Response Action Outcome is appropriate to
support the RAM Completion Statement and project closure without any restriction of Site
activities or reliance on additional passive treatment provided beyond project closure.
A review of cost and feasibility to meet background conditions through additional soil
removal was considered as part of this RAM, in accordance with the provisions of 310 CMR
40.1020. Residual EPH/PAH and VPH/BTEX impact in soil is located beneath the footprint of a
building noted as a permanent structure and further isolated beneath a poured fill cap. In
consideration of the logistics associated with the additional removal of isolated soils at depth,
such remedial actions would result in significant endangerment to the structure wherein worker
safety would be compromised. Further, wherein laboratory analytical reports document soil
conditions along the extent of the excavation as less than the S-1/GW-3, Method 1 — Risk
Characterization standards, additional soil removal is not justified wherein no significant
reduction in risk would be accomplished.
As such, current environmental conditions associated with non-persistent, naturally
degrading petroleum hydrocarbons within isolated soils meet the "Conditions of Categorical
Infeasibility" established in Section 9.3.2 of the MA DEP policy "Conducting Feasibility
DECEMBER 19,2008 FUCCU LOBEA08-10044
PAGE 16 OF 16 RAMC w/CLASS A-2 FAO RTN 4-21596
Evaluations Under the MCP" (04-160), as specifically pertaining to Section 9.3.2.1,
"Excavations Under Permanent Structures", and Section 9.3.2.3, "Remediation of Degradable
(Nonpersistent) Contaminants". Therefore, such soil removal without significant risk reduction
is considered practically infeasible as logistically and financially unjustified.
The findings of this investigation, as represented herein, set forth the rationale and
technical justification f6r the LSP Opinions offered, as established by the certifications made on
the attached Response Action Outcome Statement (BWSC-104) and the 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.

Dear Ms. McLaughlin,

BENNETT ENVIRONMENTAL ASSOCIATES, INC. (hereinafter referred t as `BRA") r}'
has prepared the following Release Abatement Measure Plan (RAMP) and upporting
.Documentation as a summary of release discovery and environmental assessment conducted at
the above-referenced property as associated with a historic fuel oil release and the identification
of a 120-Day condition. Additionally, the RAMP outlines the proposed remedial response
actions to be undertaken to mitigate potential human exposures and environmental impacts in
accordance with the provisions of 310 CMR 40.0440 where there is a threat of groundwater
impact. Environmental assessment activities have been conducted to qualify the magnitude and
extent of significant soil impact associated with a previously unidentified historic release of an
unknown quantity of #2 fuel oil in an earthen crawl space beneath the southern portion of the
dwelling.
The excavated area of the former tank is clearly visible within the crawl space. An initial
investigation determined that 1 to 2 feet of soil overlies a concrete slab which was beneath the
former tank and that the slab does not extend to the vertical limit of the crawl space interior or
exterior sidewalls. Fuel oil apparently flowed over the slab to the edge of the slab and entered
into the underlying soils. The vertical extent of soil contamination has been determined to
extend at least to 16' below grade surface (bgs) at the FIB-5 sampling location and, as such,
represents a threat of groundwater impact(as precluding)•a Limited Removal Action (LRA),
wherein environmental monitoring beyond soil removal is appropriate and-necessary in review of
potential exposure risks. As such, a Release Abatement Measure (RAM) Plan, with Release
Notification, is being submitted for soil removal operations and construction of a sub-slab

venting system to mitigate potential exposure risks and facilitate any potential future treatment of
residually impacted soils. Monitoring wells have been installed and tested in consideration of
potential groundwater impacts. Additional environmental assessment activities are prescribed
herein to further evaluate cleanup performance and exposure risks, following soil removal
operations. This information will be used to determine the need, if any, for additional treatment
of any significant residual soil impacts or groundwater impacts to meet regulatory closure
objectives for a Class A, Response Action Outcome (RAO).
The Release Abatement Measure Plan prescribes the excavation and off-site recycling of
some 15 to 25 cubic yards of fuel oil contaminated soils from within an approximate 8' x 6' x 4'
(D) [10' bgs] area. This work will be accompanied by end-point sampling of sidewall and
bottom-of-hole (BOH) areas and the re-sampling of previously installed groundwater monitoring
wells. Soil and groundwater samples will be submitted for laboratory analysis of petroleum
hydrocarbons in accordance with the current VPH/EPH Implementation policy (WSC-02-411).
Some TPH analyses may be utilized as a cost saving measure wherein TOV screening and or
field Dexsil Petroflag testing indicates low level or background conditions. Subsequent to the
removal of contaminated soils, a structure venting system will be installed along the bottom-of-
hole area to provide exterior ventilation of any potential residual organic vapors from the area of
excavation. The structure venting system can also be retrofitted to serve as a delivery system for
remedial additives to the subsurface for potential in-situ treatments if necessary or be adopted for
Level 1, ambient air screening as consistent with MA DEP Policy WSC-02-411, Implementation
of MA DEP VPH/EPHApproach.
Future environmental assessment/monitoring activities will dictate the need for any
additional remedial measures to be represented as a RAM Modification in the next RAM Status
Report to be filed within 120 days of this filing should regulatory closure standards not be met.
Additional RAM Status Reports, if necessary, will be filed every six months thereafter.
Remedial response activities proposed herein, and potentially to follow, are intended to mitigate
any potential Critical Exposure Pathways (CEPs) and to facilitate a permanent solution in order
to mitigate potential risks to identified human and environmental receptors in support of a Class
A, RAO within the one-year statutory deadline to avoid Tier Classification and Disposal Site
assignment. The proposed RAM Plan is being presented in accordance with the provisions of the
Massachusetts Contingency Plan (MCP), 310 CMR 40.0000, as specifically pertaining to 310
CMR 40.0440.
The information herein serves as the technical rationale and justification for the response
actions proposed within, which include the excavation of some 15 to 25 yards of contaminated
soils, the construction of a sub-slab venting system and environmental monitoring to support
project closure based on a preponderance of physical evidence wherein a condition of "No
Significant Risk" is achieved. This work has and will continue to proceed under direct LSP
oversight in a manner consistent with the MCP Response Action Performance Standards (RAPS)
pursuant to 310 CMR 40.0191 and the QA/QC policies of BENNETT ENVIRONMENTAL
ASSOCIATES, INC. The facts and statements herein are, to the best of our knowledge, a true

and accurate representation of the Site activities, remedial response actions and environmental
conditions associated with the project and LSP Opinions acknowledged by the certification on
the attached BWSC-106 Transmittal Form.
ENVIRONMENTAL CONDITIONS [Refer to Appendix A]
The subject property at 293 Sea Street is noted on the Town of Barnstable Assessor's
Map 306 as Parcel 78 and is located along the northwest corner of the Sea Street/Stetson Street
intersection [Refer to Figure 1]. The residentially zoned property contains approximately 0.3
acres of land area and is developed by a two-story residential style building constructed in
1900+/-. This building has historically and is currently being used as a private, single-family
residence. The surrounding area is developed in similar use, as characterized by residential
properties. Access to the subject property is unrestricted with high frequency/high intensity of
use and children potentially present. Access to the area of release, however, as within the crawl
space of the subject building and is restricted with low frequency/low intensity of use with
children potentially present as infrequent visitors. Residents of the dwelling are identified as the
primary potential human receptors to any ingestion, inhalation or dermal contact exposures.
Monitoring well installation, conducted September 25, 2008, indicated that groundwater
exists at + 25' bgs. Regional groundwater contours indicate a southerly flow direction towards
Hyannis Harbor (0.5 mi south) and Lewis Bay (0.75 mi southeast). Static water level
measurements conducted on September 25 (low tide) and September 30 (high tide) indicate
however, that local groundwater flow at the Site is westerly towards Stewart's Creek and
associated wetlands, located approximately 0.25 miles to the west. As such, Stewarts Creek and
the associated wetlands are presently identified as the potential environmental receptors pending
confirmation of groundwater flow direction and seasonal/tidal variations.
According to the MA DEP BWSC GIS mapping program, the subject property is located
within a medium yield, non-potential drinking water source area (NPDWSA) as attributed to
housing density in an urbanized area. The property does not fall within the Zone II Protective
Radius of any Public Water Supply (PWS), nor is it located within the Zone A protective radius
of any surface water reservoir. No private wells are known to exist within 500' of the Site
wherein the area is serviced extensively by the Town of Barnstable municipal water supply and
distribution system. Based on this mapping and field observations, the GW-3 groundwater
category is applicable under Method 1 —Risk Characterization, per 310 CMR 40.0974. Based on
Site conditions relative to frequency/intensity of use and accessibility of soils, wherein the release
area is within the crawl space of the basement of the subject building, the S-2 and S-3 (GW-3)
Method 1 —Risk Characterization standards are applicable to soil impact in accordance with the
provisions of 310 CMR 40.0975. In review of all foreseeable future uses and activities at the
Site, the most restrictive S-1/S-2/S-3 (GW-3), Method 1 — Risk Characterization standards are
I considered. These standards were developed in consideration of potential ingestion, inhalation
and environmental/dermal contact exposures and in review of potential leaching of contaminants
to groundwater.
OCTOBER 24,2008 FUCCILLO/BEA08-10044
PAGE 4 OF 13 RELEASE ABATEMENT MEASURE PLAN
BACKGROUND [Refer to Appendix B]
BEA received a phone call from the property owners during the weekend of August
23/24, 2008. The homeowners were in the process of selling the house and a home inspector
detected the presence of a fuel oil odor in the crawl space area. A visual inspection evidenced
what appeared to be an excavation with an adjacent pile of dirt that apparently was cast from the
excavation. No public records of any permits relative to the former existence or removal of a
fuel tank for the property could be located. Additionally, forensic evaluation of the degree and
amount of hydrocarbon degradation indicated that the fuel oil residuals were significantly
degraded as indicating that the release had occurred at least 10 years earlier and prior to the
current owner's purchase of the property. At the time the current owners took possession of the
property in 2001, the domestic heating already had been converted to natural gas and the storage
tank had been removed.
BEA contracted with the homeowners, who live out of state, to meet with their realtor,
photo-document conditions within the crawl space area and conduct limited soil sampling and
analysis to qualify environmental impacts and determine if release notification and/or remedial
response liability was present under the provisions of 310 CMR 40.0000. These results and
follow up assessment activities are summarized in the RAMP as follows.
ENVIRONMENTAL ASSESSMENT [Refer to Appendix B]
Soil
BEA conducted the above noted initial soil sampling on August 27, 2008 in the earthen
crawl space under the addition on the south side of the dwelling. The homeowners had indicated
that their perspective buyers home inspector had noted a petroleum odor in this area. Analytical
results from BEA's two initial sampling locations HB-1 and HB-2 immediately above a buried
concrete slab (initially thought to have supported the former oil tank) reported total petroleum
hydrocarbon(TPH)concentrations of 12,000 parts per million(ppm) and 7,800 ppm respectively.
These concentrations are significantly above the Site-specific RCS-1 Reportable Concentration
threshold of 1,000 mg/kg and the applicable S-3/GW-3, Method 1 — Risk Characterization
standard of 5,000 mg/kg. This testing further indicated that more than 2 yards of soil had been
impacted above the aforementioned standards.
Wherein a 120-Day Reportable Condition was identified, BEA returned to the property on
September 8, 2008 to collect additional sidewall samples and advance additional hand borings in
the areas at the perimeter of the buried concrete slab, towards defining the extent of significant
soil impacts and potential for groundwater impacts. BEA collected sidewall samples from the
dug out area of the crawl space for field testing and advanced hand borings adjacent to the area of
documented impacts: Hand borings HB-3 and HB-4 were advanced to 6' and 8' feet below grade
OCTOBER 24,2008 FUCCILLOBEA08-10044
PAGE 5 OF 13 RELEASE ABATEMENT MEASURE PLAN
surface (bgs) off of the east and west ends of the exposed concrete slab, respectively. Borings at
these locations were limited by available headroom and the friable nature of soils underlying the
dwelling. Field screening of soil samples from HB-3 and HB-4 reported low-level total organic
volatiles (TOV) concentrations from zero to 2.4 parts per million(ppmv).
Hand boring, HB-5, was advanced to a depth of 16 feet bgs between the paved driveway
and building footing, immediately adjacent to the crawl space release area [Refer to attached site
plan]. This hand boring was angled to intercept soils under the release area. Soils at the HB-5
location consisted of loose, medium to coarse grain sands with nominal cohesion. Field
screening of soil samples from HB-5 reported moderate TOV concentrations from zero to 44
ppmv and increasing with depth. Groundwater was not encountered at the HB-5 location as
projected at 25' below existing grade.
Soil samples HB-5: 8'-10' and 12'-14' were submitted for MA Certified laboratory
analysis of TPH and the 15'-16' interval sample was submitted for laboratory analysis of
extractable/volatile petroleum hydrocarbons (EPHNPH). Analytical results were received on
September 11, 2008. The analyses reported TPH concentrations in the HB-5: 8-10' sample as
1,900 parts per million (ppm) and in the HB-5: 12-14' sample as 1,100 ppm. However, the
"worst case", TOV-biased HB-5: 15-16' sample reported EPH and VPH carbon range and target
analyte concentrations as less than the applicable S-3/GW-3 standards. As such, the TPH sample
(HB-5/8'-10'; 1,900 ppm) was re-analyzed for the risk-based EPH/VPH analysis, as was the HB-
4: 6'-8' sample, in order to quantify the magnitude of impact in the consideration of risk, as
critical to the formulation of a remedial strategy. These analytical results were received the
afternoon of September 16, 2008 and reported all fractional VPH/EPH standards and target
analytes at concentrations less than the applicable S-3/GW-3, Method 1 — Risk Characterization
"cleanup" standards. These results indicate that the excavation of soils to 8' bgs in the area of
release should meet closure objectives. As such, a + 4-6' excavation to a depth of 8-10' bgs is
proposed within this RAMP. Although this testing indicates that the S-1/GW-3 standards are
met in soil samples below 8' bgs, residual soil impacts extent below 16' bgs and indicate the
potential for groundwater impact. As such, the installation and testing of monitoring wells was
prescribed to assess this potential.
The sum of the laboratory analytical results for the soil samples submitted to date is presented in
Table I and Table II. The significance of the laboratory results as they relate to potential
exposure risk is further discussed in the Risk Characterization section of this report. The
significance of these laboratory results as associated with proposed remedial response actions is
further discussed in the Release Abatement Measure Plan section of this report.

Groundwater
BEA returned to the Site on September 25, 2008 to direct test borings and the installation
of monitoring wells as performed by Jenkins Well Drilling of Brewster, MA [Refer to Site Plan].
Discrete soil sampling along the capillary fringe at the MW-1, MW-2 and MW-3 locations
reported no TOV concentrations as consistent with background and indicating no significant
groundwater impact in these wells. The monitoring wells were subsequently secured before BEA
departed the Site. All soil samples were placed in the appropriate laboratory containers for
potential EPHNPH and target analyte analyses and field preserved on ice. Based upon field
screening results, no samples were submitted for laboratory analyses. BEA conducted
monitoring well development, aquifer characterization and established top-of-casing elevations
the same day.
BEA personnel returned to the site on September 30, 2008 to re-gauge, purge and
subsequently sample all three monitoring wells for laboratory analysis of total petroleum
i
OCTOBER 24,2008 FUCCILLOBEA08-10044

hydrocarbons (TPH) as a cost savings measure to serve as an indicator for any environmental
impact. The groundwater samples were collected in appropriately preserved laboratory
containers and field preserved on ice. BEA personnel re-gauged groundwater elevations in all
wells and confirmed top-of-casing elevations in order to qualify Site-specific groundwater flow
direction as more westerly than suspected. Well gauging and static water level measurements at
high and low tide indicate that there is no apparent tidal influence on groundwater beneath the
site. At the time of this reporting, Site-specific groundwater flow appears to be westerly and as
such only MW-2 is in a downgradient location as representative of potential downgradient
groundwater impacts. However, due to the minimal spatial separation of these wells and the
sensitivity of the measuring equipment wherein the difference in groundwater elevations between
wells is 0.02', the need for an additional monitoring well will be further evaluated by additional
groundwater gauging and the evaluation of groundwater flow variability. A proposed monitoring
well location is shown at the back of the property as a contingency under the RAMP [Refer to
Site Plan—Appendix A].
A series of rising-head slug tests were performed at monitoring well MW-3 to qualify
hydraulic conductivity in review of aquifer characteristics and solute fate and transport
mechanisms. The Geraghty and Miller AQTESOLV program was employed to interpret the
results of the slug tests wherein a hydraulic conductivity of 38.31 feet per day was computed as
consistent with the clean, medium to coarse sands encountered within the upper portion of the
aquifer. Based on the calculated hydraulic conductivity and hydraulic gradients reported along
specific groundwater flow vectors from MW-1 to MW-2 and MW-1 to MW-3, the groundwater
velocity from the release area was reported as 0.12 ft/day. With a retardation factor of 10%, the
Time of Travel from the release area to MW-2 would be 184 days [Refer to Computations in
Appendix B].
Groundwater samples collected from all monitoring well locations reported TPH
concentrations as BRL with reporting limits less than the applicable GW-3, Method 1 — Risk
Characterization standards. As such, no groundwater impact is indicated at this time as subject
to confirmation of monitoring well utility and data reliance as downgradient from the release
area. The significance of these laboratory results is further discussed in the following Risk
Characterization section of this report.
RISK CHARACTERIZATION/IMMINENT HAZARDS [Refer to Appendix D]
Soil
As presented, the S-2 and S-3 (GW-3) soil categories are applicable to potentially
accessible and isolated soils within the defined area of release under current Site conditions in
consideration of exposures under Method 1 - Risk Characterization, as consistent with the
provisions of 310 CMR 40.0933. For the purposes of risk characterization in consideration of
foreseeable future uses, the most restrictive S-1 (GW-3), Method 1 - Risk Characterization
standards are further considered relative to potential ingestion, inhalation and dermal contact
i
OCTOBER 24,2008 FUCCILLOBEA08-10044
PAGE 10 OF 13 RELEASE ABATEMENT MEASURE PLAN
exposure risks to identified human and environmental receptors. Laboratory analysis has
reported TPH concentrations as significantly greater than the applicable Method 1 — Risk
Characterizations standards in a 8' x 6' x 4' (D) area (8-10' bgs) within the earthen crawl space
under the footprint of the dwelling as driving the need for proposed soil removal and recycling as
representing a potential significant risk to identified receptors. These concentrations further
indicate the potential leaching of contaminants to groundwater.
Laboratory testing of risk-based, fractional EPH/VPH data has further been used to
qualify the vertical extent of significant soil impact and threat of groundwater impact wherein the
most restrictive S-1/GW-3, Method 1 —Risk Characterization standards are met. Such testing at
the HB-5 location reported fractional VPH/EPH and target analytes at concentrations less than
the S-1/GW-3, Method 1 —Risk Characterization standards in the 8-10' and 15-16' bgs samples.
This analysis indicates that residual soil impact in potentially accessible soils at a depth greater
10' bgs represents a condition of No Significant Risk. In the review of cost to benefit and risk,
soil removal below 10' is practically infeasible. Excavation of soils below 10' bgs represents a
disproportional cost, risk to workers and property damage without reduction in risk, wherein the
most restrictive S-1/GW-3 standards are met. However, since low-level concentrations exist in
soils beyond 16' bgs with groundwater projected within 25' bgs, there still could be a threat of
groundwater impact and associated risks are being investigated.
Groundwater
As noted above,the GW-3 groundwater category is applicable in consideration of Method
1 - Risk Characterization at the Site as based on the NPDWA designation wherein ingestion
exposures are not considered as a foreseeable exposure risk. Furthermore, based on the depth of
groundwater, inhalation exposures from impacted groundwater area also not considered a
foreseeable exposure risk. The GW-3 standards are developed in consideration of any significant
environmental impacts and potential dermal contacts associated with impacted groundwater. The
results of initial groundwater testing has reported no groundwater impact wherein TPH
concentrations are reported as BRL and the reporting limit concentrations are significantly less
than the GW-3, Method 1 — Risk Characterization standards. As such, a condition of No
Significant Risk is apparent as requiring additional investigation of groundwater flow variation
and solute transport to qualify potential exposure risks.
Imminent/Substantial Hazard Evaluation
Access to significantly impacted soils within the earthen crawl space is limited with the
area capped by poly-sheeting and passive venting provided. As such, no ingestion or dermal
contact exposures are complete. TOV monitoring of the living space reports no detectable
organic vapors (0.1 ppmv) and no persistent petroleum odor is noted as indicating no significant
inhalation exposures at the present time. As such, No Substantial or Imminent Hazards to the
dwelling occupants or visitors is apparent under current conditions.
I
OCTOBER 24,2008 FUCCILLOBEA08-10044
PAGE 11 OF 13 RELEASE ABATEMENT MEASURE PLAN
Furthermore, since the area of the release and defined Site are under the footprint of the
dwelling, the area is not subject to rainfall infiltration and there is no additional leaching of
contaminants to the groundwater. Available groundwater data from monitoring wells
intermediate to defined environmental receptors indicated no groundwater impacts. Additionally,
based on the hydrogeologic properties of solute transport and distance to potential environmental
receptors, No Imminent or Substantial Hazard conditions related to environmental receptors
appears to be present at the current time as to be qualified by future testing.
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 significant soil impact from the identified
release area noted on the Site Plan. A licensed shoring contractor will install structural support
for the interior partition and exterior wall of the crawl space area, in advance of excavation
operations. The environmental contractor will then remove contaminated soils with via soil
vactoring and direct load into the vactor truck. Personal protection and safety standards for BEA
are specified in the Site Specific Health and Safety Plan (HASP) outlined in Appendix F. Site
Contractors are required to adopt and monitor compliance with the HASP or prepare and
implement their own Health and Safety Plan.
BEA will inspect and document the removal of some 15-25 yards of contaminated soils
from the projected area of soil removal as approximately 8' x 6' x 4' (D) [6' bgs to 10' bgs]. Field
PID screening and Dexsil field-testing will be utilized as technical guidance in support of
excavation operations. This material will be transported directly on an executed Bill of Lading to
the Aggregate Industries facility in South Dennis, MA for asphalt recycling. At which point field
screening indicates the effective removal of all significant soil impact; end-point samples will be
collected and preserved for MA Certified analysis of EPH/PAH and VPH/BTEX in review of
remedial response performance and risk characterization. TPH analysis may be used as a cost
saving measure wherein field-testing indicates petroleum impacts are clearly absent.
Upon the excavation and disposal of all significant impact as supported by laboratory
analysis, a sub-slab venting system will be constructed and installed in the former area of
significant impact. The venting system will be constructed of 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 component, run outside the footprint of the building and connected to a
wind turbine for the passive venting of residual petroleum volatiles outside the building. The
venting system will also provide the flexibility to deliver remedial additives if necessary to
mitigate potential residual impact in soils or to potentially treat groundwater if necessary. The
SVE/Sub slab venting system can also be utilized to evaluate potential vapor entry into the
occupied structure via Level 1, Soil Gas Screening. Such work will be compiled and reported in
a RAM Status Report (RAMS) or RAM Completion Report (RAMC) within 120 days of this
filing.
OCTOBER 24,2008 FUCCILLOBEA08-10044
PAGE 12 OF 13 RELEASE ABATEMENT MEASURE PLAN
As noted above, two rounds of monitoring well gauging have resulted in .similar
calculated groundwater flow vectors with groundwater flowing northwesterly, bearing 295
degrees. These calculations support the necessity to install at least one additional monitoring
well in the relatively inaccessible backyard or garage area. The need for this well will be
evaluated by additional groundwater gauging and the well will be installed and tested
accordingly. Each downgradient monitoring well will be sampled and analyzed for groundwater
impact at least twice as consistent with the VPH/EPH Guidance Policy WSC-02-411.
ENVIRONMENTAL MONITORING
Subsequent to the completion of soil removal operations and end point soil analysis, BEA
will monitor TOV concentrations within the dwelling and at the venting system riser in
consideration of indoor air quality as consistent with the provisions of the VPH/EPH Guidance
Policy WSC-02-411 and 310 CMR 40.0942. The reported TOV concentrations will be recorded
in review of the potential for adverse impact to indoor air quality.
Based on the historic nature of the release, groundwater monitoring will be conducted at
least twice as indicated. EPH/VPH methods with target analytes will be utilized in downgradient
wells. TPH analysis may be utilized in upgradient wells as a cost saving measure to screen for
petroleum hydrocarbons impacts. During sampling events, all associated monitor wells will be
gauged to confirm groundwater flow direction. 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 Inspectors Daily Record of Work Progress reports will be completed to document
Site inspections and environmental monitoring as consistent with the QA/QC Policies of BEA
outlined within Appendix E.
CONCLUSIONS
The Release Abatement Measure Plan, represented by this filing, will employ an
aggressive soil removal strategy for the excavation and recycling of some 15-25 yards of
significantly impacted soils from within the identified release area. Field PID screening and
Dexsil Petroflag testing as performed by BEA personnel will direct excavation operations. This
work will eliminate the contaminant source in all accessible and potentially accessible areas and
facilitate the construction of appurtenances that can be utilized for additional treatment of
residual hydrocarbons as may be necessary. The venting system will provide a preferential
pathway for the removal of organic vapors from isolated soils and vent such vapors outside the
subject building. In the future, the sub-slab system may also serve as a delivery system for
remedial additives if necessary.
It is our intent to proceed with the proposed remedial response activities immediately
following the submittal of this report, as a real estate transfer is pending. The first RAM Status
Report with proposed modifications will be submitted within 120 days of this filing. Subsequent
OCTOBER 24,2008 FUCCI LLOBEA08-10044
PAGE 13 OF 13 RELEASE ABATEMENT MEASURE PLAN
RAM Status Reports will be filed every six months thereafter until a preponderance of physical
evidence supports a condition of"No Significant Risk" and Response Action Outcome (RAO)
objectives are met as supporting a RAM Completion Statement.
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 Forms (BWSC-106). The LSP Opinions
are based on available data and regulations in effect at the time of this reporting.
