1.0 INTRODUCTION
On behalf of F.W. Webb Company (F.W. Webb), Alliance Environmental Group, Inc. (AEG) has
prepared this Release Abatement Measure (RAM) Plan for the Former Universal Steel & Trading
Company Site located at 297‐305 Bridge Street in Salem, Massachusetts (hereafter referred to
as the “Site”). This RAM Plan was prepared in accordance with Section 310 CMR 40.0444 of the
Massachusetts Contingency Plan (MCP) to facilitate proposed construction activities at the Site,
which is identified by the Massachusetts Department of Environmental Protection (MassDEP) as
Release Tracking Number (RTN) 3‐11726.
In January 2015, a Phase III Remedial Action Plan (RAP) and Permanent Solution with Conditions
Statement for the Site was submitted to MassDEP by Weston & Sampson, Inc. (W&S) of
Peabody, Massachusetts. This submittal was based on the implementation of an Activity & Use
Limitation (AUL) encompassing the entire Site property. The AUL, which was filed with the Essex
County Registry of Deeds, Southern District, in December 2014, was established to restrict
access to residually impacted soil at the Site as discussed in subsequent sections of this report.
2.0 NAME OF PERSON CONDUCTING THE RAM (310 CMR 40.0444(1)(a))
The activities proposed in this RAM Plan are being performed for the following Potentially
Responsible Party (PRP):
F.W. Webb Company
Attn: Robert Mucciarone
160 Middlesex Turnpike
Bedford, Massachusetts 01730
(781) 272‐6600
3.0 DESCRIPTION OF RELEASE, SITE CONDITIONS, AND SURROUNDING RECEPTORS (310
CMR 40.0444(1)(b))
3.1 Site Description
The Site is located at 297‐305 Bridge Street in Salem, Massachusetts, with latitude and longitude
coordinates of 42° 31’ 22.78” North and 70° 54’ 2.78” West. The Universal Transverse Mercator
(UTM) coordinates are 4,709,597 meters North and 343,876 meters East. A United States
Geological Survey (USGS) Site Locus Map is included as Figure 1.
The Site consists of an approximately 1.2 acre parcel of land located in an area of mixed
residential and commercial use. The Site is currently used as a temporary parking lot for a
nearby Massachusetts Bay Transportation Authority (MBTA) train station. The City of Salem
opened the parking lot in October 2013 following the completion of Site remediation activities
as described below. The parking lot consists of a large central‐paved area with small landscaped
islands and vegetative buffer areas along the perimeter of the Site. Two sediment forebays are
also located at the northeast and northwest corners of the Site along Bridge Street. A
Site/Construction Overlay Plan is provided as Figure 2.
The Site historically contained several structures, including a two‐story warehouse building, two
large concrete pads, and several ancillary features such as a truck scale and paved loading areas.
Release Abatement Measure (RAM) Plan October 2015
297‐305 Bridge Street, Salem, MA Page 2
The warehouse building was demolished in 2012, and the remaining Site features were
demolished and removed as part of the Site remediation completed in 2013.
The Site is abutted by Bridge Street to the north, across which is an unpaved parking area with
railroad tracks beyond. Residential properties border the Site to the south. A F.W. Webb
plumbing supply store is located directly adjacent to the Site to the east. To the west is
Beckford Street, across which is a parking lot associated with Alpha Auto Sales.
3.2 Surrounding Receptors
Human Receptors: As mentioned above, an AUL was applied to the Site in December 2014. The
AUL prohibits the future use of the Site as a residential property. Potential human receptors
currently include MBTA employees, construction or other service‐related workers, and the
general public (as visitors or trespassers). Current and future workers at the Site are considered
to include males and females at a minimum age of 16 years; these workers may include women
of childbearing age. Customers visiting the subject property, considered as the general public,
incorporate all segments of the population including infants, children and adults. Children (ages
1 to 8) and students are only anticipated to access the Site infrequently as visitors.
No sensitive institutions such as schools, hospitals, daycare centers and long‐term healthcare
facilities were identified within a 500‐foot radius of the Site.
Drinking Water Receptors: Based on the MassDEP Site Scoring Map dated September 11, 2015,
and provided as Figure 3, the Site is underlain by medium and high‐yield aquifers designated as
a Non‐Potential Drinking Water Source Area. There are no Current or Potential Drinking Water
Source Areas located within one‐half mile of the Site. Additionally, no private water supply
wells are known to be located within 500 feet of the Site.
Environmental Receptors: According to the Site Scoring Map, no Areas of Critical Environmental
Concern (ACECs), certified vernal pools, wetlands, or sensitive habitat areas as mapped by the
Natural Heritage & Endangered Species Program (NHESP) are located within one‐half mile of the
Site. Several Protected Open Spaces are located within 500 feet of the Site to the north, south,
east and west.
The nearest surface water body is the North River Canal, located approximately 530 feet north
of the Site. The North River Canal connects with the North River located on the eastern side of
the North Street Bridge. The North River discharges into the Danvers River located
approximately one mile to the east. Both the North River and the Danvers River are tidal rivers,
and are connected to Beverly Harbor which is located northeast of the Site. It is also noted that
the Site is located within the Federal Emergency Management Agency (FEMA) 100‐Year
Floodplain.
3.3 History of Site Usage
In 1936, the former Universal Steel & Trading Company began operating at the Site as a metal
scrap yard. Activities conducted at the Site by the former Universal Steel & Trading Company
included processing and sorting of a variety of scrap metals, steam and hot water radiators,
metal kitchen equipment, electronics cabinets and metal building demolition debris, and
stockpiling of automotive batteries. In June 1994, the property was purchased by Tewksbury
Release Abatement Measure (RAM) Plan October 2015
297‐305 Bridge Street, Salem, MA Page 3
Industries, Inc. (Tewksbury Industries), who continued to operate the facility as a metals
recycling business under the name of Universal Steel & Trading Company. In 2012, as a result of
tax foreclosure, the City of Salem took ownership of the Site. MassDEP and MassDevelopment
subsequently provided funding to demolish the above‐grade portions of the existing Site
buildings.
3.4 Regulatory Status and Historical Remedial Activities
In November 1993, prior to acquiring the Site property, Tewksbury Industries contracted W&S
to conduct a Phase I Initial Site Investigation. As part of the investigation, W&S supervised the
installation of soil borings and groundwater monitoring wells at the Site. Based on the analytical
results, soil samples collected at a depth of approximately 1.5 feet below ground surface (bgs)
contained total petroleum hydrocarbons (TPH), metals (cadmium, lead and mercury) and
polychlorinated biphenyls (PCBs) at concentrations above the applicable MCP RCS‐1 Reportable
Concentrations. The concentrations of TPH and PCBs at several locations also exceeded the
associated Upper Concentrations Limits (UCLs). With regard to groundwater, the analytical
results indicated that PCBs and vinyl chloride were present at concentrations above the
applicable MCP Method 1 GW‐2 Groundwater Standards at one location on‐Site. Based on the
results of the initial investigation, W&S conducted supplemental field activities in July 1994. The
supplemental activities included the collection of additional groundwater samples and field
testing to evaluate hydrogeologic and groundwater flow characteristics at the Site. The results
indicated that volatile organic compounds (VOCs) and PCBs were both below the applicable
Method 1 GW‐2 Groundwater Standards. However, the detections of TPH, metals, and PCBs in
soil in excess of the RCS‐1 Reportable Concentrations represented a 120‐day MCP reporting
condition. On October 7, 1994, W&S submitted a Release Notification Form (RNF) to MassDEP.
On December 1, 1994, MassDEP issued a Notice of Responsibility (NOR) to Tewksbury Industries
and assigned RTN 3‐11726 to the Site.
Based on the results of the Phase I Initial Site Investigation, W&S submitted a RAM Plan to
MassDEP in May 1995 to facilitate the removal of a portion of the PCB‐ and TPH‐impacted soil
identified at the Site. As part of the RAM, MassDEP requested the collection of additional
surficial soil samples for PCB analysis from the four residential properties abutting the Site to
the south. A total of five additional soil samples were collected from these residential
properties in June 1995. The analytical results indicated that the PCB concentrations were less
than 10 milligrams per‐kilogram (mg/kg) with the exception of one sample which exhibited a
PCB concentration of 32 mg/kg. The presence of PCBs in soil within twelve inches of the ground
surface, in excess of 10 mg/kg and within 500 feet of a residential dwelling triggered an
Imminent Hazard (IH) condition pursuant to CMR 40.0320(2)(b). MassDEP was notified of the
condition on July 6, 1995, and assigned RTN 3‐12653 in response.
Following notification of the IH condition, MassDEP requested the installation of a fence
between the Site and the four southerly abutting private properties to restrict access. MassDEP
also requested that additional assessment be completed as part of Immediate Response Action
(IRA) activities in order to evaluate the extent of PCB contamination at the adjacent properties.
In July 1995, W&S collected nine soil samples (S‐1 through S‐9) from the top foot of soil at each
selected location. In addition, one sample was collected from a depth of 12 to 18 inches bgs at
the location where the maximum PCB concentration of 32 mg/kg was previously detected.
Based on the analytical results, PCBs were not present above the laboratory reporting limits in
the soil sample collected from 12 to 18 inches bgs. However, PCBs were detected at a
Release Abatement Measure (RAM) Plan October 2015
297‐305 Bridge Street, Salem, MA Page 4
concentration of 62 mg/kg in the shallow sample collected at the property boundary of 92
Federal Street. Tewksbury Industries installed the MassDEP‐requested fence in August 1995.
In October 1995, the excavation of PCB‐contaminated soil at the southerly abutting properties
was completed under the IRA for RTN 3‐12653. As a result of the IRA activities, approximately
60 cubic yards of soil were excavated and disposed of off‐Site. W&S collected six confirmatory
soil samples from the IRA excavation area, and the analytical results indicated that the residual
PCB concentrations were all below the applicable MCP Method 1 Soil Standards. In July 1996,
RTN 3‐12653 was closed via the submittal of an IRA Completion Report and Response Action
Outcome (RAO) Statement to MassDEP.
In March and April 2000, Haley & Aldrich, Inc. (H&A) of Burlington, Massachusetts conducted
Phase II assessment activities at the Site on behalf of Creditor’s Trust, who assumed limited
responsibility for conducting response actions at the Site in accordance with a bankruptcy
reorganization plan settlement agreement between the Commonwealth of Massachusetts and
Tewksbury Industries. The assessment included the installation of additional soil borings and
groundwater monitoring wells. The results indicated the presence of arsenic, lead, PCBs,
polycyclic aromatic hydrocarbons (PAHs) and hydraulic oil in soil at concentrations above the
applicable MCP Method 1 S‐1 Soil Standards. The PCB concentrations also exceeded the UCL at
three shallow (0‐3 feet bgs) sampling locations. TPH levels at two locations and the lead
concentration at one location also exceeded the associated UCLs in samples collected from 2‐4
feet bgs. Based on the groundwater analytical results, vinyl chloride and PCBs were detected at
concentrations above the Method 1 GW‐2 and GW‐3 Groundwater Standards, respectively.
In November 2004, H&A prepared a Phase II Scope of Work (SOW) outlining additional
recommended assessment to be completed at the Site. The proposed scope included additional
surficial soil sampling, installation of downgradient monitoring wells, groundwater sampling,
and surface water and sediment sampling. H&A completed the additional surficial soil sampling
between in December 2004 and January 2005. As part of the investigation, H&A collected a
total of 307 soil samples for PCB analysis from 0‐3 inches bgs using a 10‐foot square grid across
the Site. The sampling results indicated that 254 of the 307 soil samples exhibited PCB
concentrations above 10 mg/kg. This condition was subsequently addressed via the installation
of a perimeter chain link fence to restrict unauthorized access to the Site. H&A also collected
181 soil samples from three of the southerly abutting properties in July 2006, November 2006
and January 2007. PCBs were detected above 10 mg/kg in the samples collected at the 30‐32
Beckford Street and 102 Federal Street properties. At the 30‐32 Beckford Street property, PCBs
were detected in the upper 12 inches of soil in an unpaved area, which represented a new IH
condition. MassDEP was notified of the two‐hour reporting condition, assigned RTN 3‐26449 in
response, and retained a contractor to remove the impacted soil from these properties until all
endpoint sampling results were below 1.0 mg/kg. In June 2010, RTN 3‐26449 was closed via the
submittal of a Class A‐2 RAO to MassDEP.
In 2011, W&S initiated a Phase II Comprehensive Site Assessment (CSA) at the Site. The Phase II
investigation included the advancement of 27 soil borings using a 60‐foot square grid and the
installation of three groundwater monitoring wells in the shoulder of Bridge Street to the north
of the Site. W&S also collected concrete samples from the former building floor slabs and
exterior concrete pads for analysis of PCBs. A total of 82 soil samples were submitted for PCB
analysis as part of the Phase II CSA. Of these, 29 samples contained PCBs at concentrations at or
above 1.0 mg/kg. Select soil samples were also analyzed for extractable petroleum
Release Abatement Measure (RAM) Plan October 2015
297‐305 Bridge Street, Salem, MA Page 5
hydrocarbons (EPH) with target PAHs, volatile petroleum hydrocarbons (VPH), VOCs and
Resource Conservation and Recovery Act (RCRA) 8 metals. With the exception of arsenic,
cadmium, chromium, lead, and some EPH‐related compounds, all contaminant concentrations
were below the applicable MCP Method 1 Soil Standards. The groundwater analytical results
indicated that all contaminant concentrations were below the Method 1 GW‐2 (where
applicable) and GW‐3 Groundwater Standards, with the exception of cadmium and
chlorobenzene in the sample collected from monitoring well HA‐1 located in the northeastern
portion of the Site. The analysis of the concrete samples from the interior and exterior building
slabs indicated that PCBs above 1.0 mg/kg were present at three of the sampling locations.
On June 15, 2011, W&S met with MassDEP and the United States Environmental Protection
Agency (USEPA) to review the findings of the ongoing Phase II CSA and discuss potential
remedial options for the Site. Based on this discussion and the results of a follow‐up meeting on
October 5, 2011, W&S evaluated five remedial options as requested by MassDEP and USEPA.
These five remedial options focused on the excavation and off‐Site disposal of varying quantities
of PCB‐impacted soil based on the concentrations and/or depths of impacts across the Site.
In November 2011, W&S submitted the Phase II CSA to MassDEP. W&S completed a Method 3
Risk Characterization for the Site to accompany the Phase II CSA submittal. The risk assessment
assumed that the property would be redeveloped in the future, but that future residential use
would be restricted through the implementation of an AUL. The results of the Method 3 Risk
Characterization indicated that while a condition of No Significant Risk (NSR) to public safety
existed under current and foreseeable future Site conditions, a condition of NSR to human
health did not exist at the Site due to potential for exposure to PCBs in soil.
Following the submittal of the Phase II CSA, a risk‐based remedial action alternative (RAA) was
developed for the Site. The selected RAA was derived from a combination of previously‐
discussed options, which included the removal of the top foot of contaminated soil across the
entire Site, as well as the targeted excavation and removal of deeper PCB‐impacted soils
exhibiting concentrations in excess of 50 mg/kg. The risk‐based cleanup approach also included
the removal of the PCB‐impacted concrete slabs and measures to address risk related to the
PCB‐impacted soil to be left on‐Site. These measures included capping the entire Site and
placing an AUL on the Site to prevent future residential development and restrict future Site
uses with the potential to disturb residual contaminated soils.
The selected RAA for the Site was implemented by a multi‐agency team consisting of MassDEP,
USEPA, the City of Salem, and MassDevelopment. Implementation of the RAA commenced in
December 2012 and was completed in October 2013. The excavation and removal of PCB‐
impacted soil and concrete was completed as a Removal Action by USEPA under the Emergency
Response and Removal Program (ERRP). USEPA and their remediation subcontractor,
Environmental Restoration Services LLC (ERS) of Braintree, Massachusetts, initiated the Removal
Action in December 2012 and began excavating PCB‐impacted soil in January 2013. The
excavation of PCB‐impacted materials was completed in August 2013. In total, approximately
6,380 cubic yards (9,570 tons) of PCB‐impacted soil and concrete were excavated and
transported off‐Site for appropriate disposal during the Removal Action. PCB‐impacted
materials were excavated from on‐Site as well as from the 92 and 102 Federal Street properties
abutting the Site to the south.

297‐305 Bridge Street, Salem, MA Page 6
On December 17, 2014, W&S filed an AUL for the entire Site property with the Essex County
Registry of Deeds, Southern District, in Salem, Massachusetts. The AUL was applied to the Site
to restrict certain potential exposure pathways to residually impacted soil and to ensure that
future activities associated with Site development and post‐development uses would not result
in a potential risk to human health. On January 9, 2015, W&S submitted a Phase III RAP and
Permanent Solution with Conditions Statement to MassDEP. The report concluded that a
condition of NSR had been achieved for the Site in consideration of the recently completed
remedial efforts and the implementation of the AUL.
On May 5, 2015, at the request of W&S (on F.W. Webb’s behalf), representatives of USEPA,
MassDEP, the City of Salem, W&S, AEG, and Green Leaf Construction (Green Leaf) of Leominster,
Massachusetts attended a meeting at the USEPA Region One headquarters in Boston,
Massachusetts. The meeting was conducted to discuss the proposed Site development activities
and was hosted by Ms. Kim Tisa, the USEPA PCB Coordinator. During the meeting, Ms. Tisa
raised a concern regarding whether the added weight of proposed new F.W. Webb building
components could mobilize PCBs and cause the preferential migration of PCBs in groundwater.
Subsequent evaluations performed by AEG and other parties in response to Ms. Tisa’s inquiry
are discussed below in Sections 4.4.1 and 4.4.2.
4.0 RELEASE ABATEMENT MEASURE PLAN (310 CMR 40.0444(1)(a)‐(i))
4.1 Objectives (310 CMR 40.0444(1)(c))
The primary objective of the RAM is to manage potentially impacted soil and groundwater that
may be encountered during the planned development of the Site. A proposed Construction
Overlay Plan using the existing PCB concentrations remaining at the Site is included as Figure 2.
The proposed development activities are associated with the expansion of the F.W. Webb
facility abutting the Site to the east. F.W. Webb is negotiating the purchase of the Site property
from the City of Salem. Once the Site is purchased, F.W. Webb intends to erect a new plumbing
supply store and showroom that will encompass a majority of the Site property. The new facility
will replace the existing F.W. Webb store currently located at the easterly abutting parcel. An
architectural rendering of the proposed building is included as Figure 4.
4.2 Health and Safety Plan
All proposed activities to be conducted at the Site will be performed in accordance with a Site‐
specific Health and Safety Plan (HASP). The HASP, which was prepared by qualified individuals
sufficiently trained in worker health and safety requirements, will be implemented prior to the
commencement of any activity that may disturb residually impacted soil and/or groundwater
located beneath the geotextile liner at the Site. The HASP specifies the type of personal
protection (i.e. clothing, respirators, etc.), decontamination procedures, engineering controls
and environmental monitoring necessary to prevent worker exposures to contaminated media
through dermal contact, ingestion and/or inhalation. On‐Site workers who may come in contact
with the contaminated media should be appropriately trained on the requirements of the HASP,
and the plan will be available on‐Site throughout the course of the project. The HASP will be
modified as needed to account for any observed or documented changes in Site conditions.
Release Abatement Measure (RAM) Plan October 2015
297‐305 Bridge Street, Salem, MA Page 7
4.3 Soil and Groundwater Management Plan
A Soil and Groundwater Management Plan (Soil & GW Plan) was prepared in conjunction with
the Site‐specific HASP. The purpose of the Soil & GW Plan is to outline the required procedures
for the handling, storage, and disposal of potentially impacted media encountered during the
proposed construction activities at the Site. Preparation and use of the Soil & GW Plan during
subsurface activities is required in accordance with the AUL filed for the Site in December 2014.
The Soil & GW Plan also contains provisions for the reuse of excavated soils on‐Site as fill
material if the material meets the analytical requirements previously established by USEPA.
The USEPA‐approved analytical results are summarized in the textbox shown below.
4.4 Proposed Site Redevelopment Activities
4.4.1 Geotechnical Soil Borings
On September 30, 2015, Geotechnical Services Inc. (GSI) of Boston, Massachusetts completed a
Geotechnical/Environmental Considerations opinion letter for the Site to address the concern
raised by USEPA regarding whether the added weight of proposed new F.W. Webb building
components could mobilize PCBs and cause the preferential migration of PCBs in groundwater.
The report, which is included in Appendix A, indicated that the granular fill encountered in the
upper zone of the subsurface is considered to be “undocumented fill” and is not adequate for
direct or indirect support of building foundations or floor slabs. Underlying the fill material is an
apparent weak and compressible deposit of organic silt or silty clay. As such, a total of six
geotechnical soil borings is planned to aid in the evaluation of the appropriate building
foundation design measures (refer to Figure 2 for approximate soil boring locations). During the
advancement of the geotechnical borings, AEG personnel will document visual observations and
drill rig blow counts to further characterize subsurface conditions. The borings will be advanced
to a minimum depth of 30 feet bgs or to the top of the glacial till layer (if encountered prior to
30 feet bgs).
Pending the results of the planned geotechnical investigation, F.W. Webb is considering utilizing
a stone pier system to support the building floor slab. To construct the stone columns, a
vibrating unit penetrates the overburden to the selected design depth and the resulting cavity is
filled with hard, inert stone that is free of fine particulate material. The interaction between the
stone columns and the surrounding soils is developed by the stone infill being introduced and
compacted in stages, with each lift of stone being thoroughly compacted. As a result of this
process, the stone columns and the confining soils form an integrated foundation support
system having low compressibility and improved load bearing capacity.
4.4.2 Soil Excavation and Disposal
Based on the preliminary construction plans for the proposed F.W. Webb plumbing supply store
and showroom, the facility warehouse will encompass 15,875 square‐feet (ft2) and the
Soil suitable for reuse at the Site = <10 mg/kg (under cap)
Soil suitable for disposal off‐site as non‐TSCA waste = 10 to 50 mg/kg
Soil suitable for disposal off‐site as TSCA bulk remediation waste at a TSCA‐
certified landfill = >50 mg/kg
Release Abatement Measure (RAM) Plan October 2015
297‐305 Bridge Street, Salem, MA Page 8
showroom 10,225 ft2, for a total building footprint of approximately 26,100 ft2. The primary
construction activities that will result in the generation of potentially impacted soil will include
the following:
‐ Installation of the F.W. Webb building foundation walls; and
‐ Installation of the storm water catch basins and associated drainage lines to the south
and east of the proposed building location.
On September 30, 2015, AEG prepared a Technical Memorandum for the Site in support of the
Geotechnical/Environmental Considerations opinion letter prepared by GSI for the Site in
response to the concern raised by USEPA regarding the potential mobilization and preferential
migration of PCBs in groundwater. As discussed in the Technical Memorandum, which is
included in Appendix B, PCBs are nonpolar, are heavier than water, and have relatively low
vapor pressures (10‐12 to 10‐4 atmospheres) and Henry’s Law constants (between 0.01 and 1). As
such, PCBs are only slightly soluble in water. Additionally, when compared to other chemicals,
PCBs have very high KOW (octanol/water partition coefficient) values and therefore exhibit a
strong affinity to organic carbon. These characteristics inhibit the transport of PCBs from soil to
groundwater or surface water, and cause them to bind strongly to soils. AEG therefore does not
expect that the preferential migration of PCBs in groundwater will occur as a result of either the
construction or the weight of the proposed F.W. Webb building at the Site.
AEG personnel will be on‐Site during excavation and trenching activities to document subsurface
conditions and to screen excavated soil for PCBs using a field titration kit (CLOR‐N‐SOIL® PCB
Test Kit or similar model). Per USEPA guidance, any excavated soils containing PCBs at levels
above 50 mg/kg will need to be disposed of at a Toxic Substances Control Act (TSCA) approved
facility. Soils exhibiting PCB concentrations between 10 and 50 mg/kg can be disposed of at a
RCRA Subtitle D landfill facility. Since an engineered cap will be in place, including the use of a
building vapor barrier, soils containing PCBs at levels below 10 mg/kg can be reused on‐Site
below the capped areas.
Based on the current design, a total of approximately 1,650 cubic yards (yd3) of soil will be
removed as part of the excavation/trenching activities for the F.W. Webb building foundation
wall, loading docks and Site utilities. In accordance with the MCP 40.0042(5) and 40.0444(1)(h),
F.W. Webb signed a statement of financial ability certifying that they have sufficient financial
resources to manage excavated materials in excess of 1,500 cubic yards of soil in the manner
and time frames specified in the MCP 310 CMR 40.0030. A copy of the statement of financial
ability is provided in Appendix C.
Of the estimated 1,650 yd3 of soil anticipated to be generated, approximately 10 yd3 is expected
to require disposal at a TSCA approved facility based on the proposed F.W. Webb layout and
information provided by W&S. Approximately 120 yd3 is anticipated to required disposal at a
RCRA Subtitle D landfill, and the remaining soils will be reused on‐Site or transported to a landfill
facility if on‐Site reuse is not practicable. Excavated materials will be stockpiled on and covered
with a polyethylene liner pending off‐Site disposal. If appropriately pre‐characterized,
excavated soils may also be live‐loaded into trucks and/or roll‐off containers for same‐day
transportation and disposal during certain activities.

297‐305 Bridge Street, Salem, MA Page 9
4.4.3 Excavation Dewatering and Groundwater Disposal
Based on the results of previous environmental investigations, the depth to groundwater at the
Site is typically between four and six feet bgs. As such, excavation dewatering will likely be
required to facilitate the installation of the Site utilities and certain sections of the building
foundation wall.
The volume of groundwater to be generated during station construction activities is not
expected to exceed approximately 30,000 gallons. Given the relatively small volume anticipated
to be generated, it is recommended that any groundwater infiltrating the excavations and/or
trenches be pumped into a fractionation tank to be staged on‐Site during construction. The
recovered groundwater would be analyzed for the applicable waste disposal parameters and
subsequently transported off‐Site using vacuum trucks for appropriate disposal/recycling.
4.5 Federal, State, and/or Local Permits (310 CMR 40.0444(1)(f))
A DigSafe utility clearance ticket will be required for all subsurface activities to be performed as
part of the building construction. In addition, F.W. Webb or its authorized contractor will obtain
the applicable permits and approvals from the City of Salem including, but not necessarily
limited to, the following: zoning approvals/permit, building permit, sanitary sewer permit,
electrical permits, and exterior signage approvals/permit.
Should the on‐Site treatment and local discharge of treated groundwater be selected to
facilitate excavation activities below the water table, a National Pollutant Discharge Elimination
System (NPDES) permit application will be prepared for submittal to USEPA.
Prior to the disposal of any solid or liquid waste, approvals from the selected disposal facilities
will be required. These approvals will be based on facility review of the completed waste
profiles and supporting documentation for all media, including laboratory analytical results. The
waste materials will be transported using Massachusetts Bills of Lading (BOLs), Material Shipping

Technical Memorandum
DATE: September 30, 2015
TO: Mr. Andy McBeth
Green Leaf Construction
FROM: Joel Walcott, PE
Felix Perriello, CHMM, CPG, LSP, LEP
PROJECT: 297-305 Bridge Street, Salem, Massachusetts
Alliance Environmental Group, Inc. (AEG) has prepared this Technical Memorandum for
the above-referenced location (the Site) in response to a concern raised by Ms. Kim Tisa
of the United States Environmental Protection Agency (USEPA) during the May 5, 2015,
meeting between Green Leaf Construction, Weston & Sampson, the City of Salem,
Massachusetts Department of Environmental Protection (MassDEP), AEG and USEPA.
Ms. Tisa inquired as to whether the added weight of the proposed new F.W. Webb
Company (F.W. Webb) building at the Site could mobilize polychlorinated biphenyls
(PCBs) and cause the preferential migration of PCBs in groundwater.
On September 11, 2015, Geotechnical Services Inc. (GSI) of Boston, Massachusetts
prepared an opinion letter entitled “Geotechnical/Environmental Considerations.” The
opinion letter indicated that the stone columns to be used to support the proposed
building would result in little disturbance to surrounding tributary soils, and that the
groundwater regime would remain unaltered by the introduction of these columns and the
subsequent building installation. This memorandum, which focuses on the fate and
transport of PCBs in the environment, has been prepared to supplement the GSI letter and
further address Ms. Tisa’s initial query.
PCBs comprise a class of 209 organic chemicals that were commonly used for various
applications from approximately 1929 until 1979, PCB manufacturing, processing,
distribution and use was banned in the United States1. The basic chemical structure of
PCBs includes two benzene rings (the biphenyl), and between one and ten chlorine atoms
substituted on each of the benzene molecules. PCBs vary in consistency from thin, light-
colored liquids to yellow or black waxy solids, and exhibit a range of toxicity levels. The
exact fate and transport of PCBs is directly related to the specific structure of the
individual PCB compounds. In general, however, PCBs do not readily break down once

2
released to the environment and are therefore slow to degrade. They persist because the
organisms that naturally degrade such wastes are unable to break the strong bonds made
between the chlorine atoms and the biphenyl structure.
PCBs are nonpolar, are heavier than water, and have relatively low vapor pressures (10-12
to 10-4 atmospheres) and Henry’s Law constants (between 0.01 and 1). As such, PCBs
are only slightly soluble in water2. Additionally, when compared to other chemicals,
PCBs have very high KOW (octanol/water partition coefficient) values and therefore
exhibit a strong affinity to organic carbon. These characteristics inhibit the transport of
PCBs from soil to groundwater or surface water, and cause them to bind strongly to soils.
In groundwater, a small portion of PCBs will dissolve and can potentially be transported
in suspension, but the majority will bind to organic particles and soils/sediments. The
finer the soil or sediment particles, the more easily PCBs are adsorbed.
Based on the above information, and in consideration of the planned building
construction methods (i.e., the stone columns), AEG does not expect that the preferential
migration of PCBs in groundwater will occur as a result of either the construction or the
added weight of the proposed F.W. Webb building at the Site. As indicated in the
geotechnical opinion letter provided by GSI, there will be little disturbance to the
tributary soils and thus the present state of effective stress would be unaltered due to the
fact that the stone columns would respond to the load while the tributary soils remain
dormant. In addition, since PCBs exhibit a strong affinity to organic carbon, migration in
groundwater will be unlikely.
