Introduction
On behalf of the Massachusetts Bay Transportation Authority (MBTA) of Boston, Massachusetts,
AECOM Environment (AECOM) is conducting a remediation program at the Readville 5 Yard facility
(“the Site”) located on Industrial Drive at the border between Dedham and Boston, Massachusetts. The
Site is a 42-acre property contaminated with metals (primarily lead and arsenic), polychlorinated
biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs) and petroleum hydrocarbons. The Site is
abutted by residential properties to the north and west and by industrial properties to the south and east.
Vehicular access to the Site is via a locked gate on Industrial Drive to the south. Rail access is available
via tracks to the east but may require infrastructure improvements or rail switch rehabilitation before
being usable.
Under the Massachusetts Contingency Plan (310 CMR 40.0000 – the MCP) the Site is identified by the
Massachusetts Department of Environmental Protection (MassDEP) as Release Tracking Number
(RTN) 3-2856.
The preferred remedial alternative involves the excavation, stabilization, and off-site transportation and
disposal of over 10,000 tons of soil contaminated (primarily) with lead and arsenic. To mitigate impacts
to the adjacent community, the MBTA has developed a Transportation Management Plan (TMP) to
minimize the potential impacts due to noise, dust and traffic associated with the off-site disposal of the
contaminated soil. This document outlines the plan to be implemented during the remediation activities.
Section 2 presents background information on the Site and the proposed remediation process.
Section 3 presents the procedure for the two alternatives for off-site soil transport; truck and rail.
Section 4 describes required vehicle decontamination procedures.
Section 5 describes work day limitations on truck/rail car movement designed to minimize off-site noise
and traffic impacts.
Section 6 provides references and citations.
Changes to the TMP will be documented using the Amendment Form presented in Attachment A.
Attachment B provides a figure depicting the required truck route.

Background
AECOM is overseeing the remediation of the Site, including removal of soil, in order to insure that the
residual soil concentrations meet the risk-based commercial /industrial worker standards developed to
achieve a Permanent Solution at the Site. Soil removal activities are expected to be conducted for
approximately six months starting in August 2011, as described in the Phase III and Phase IV (AECOM,
2009).
Highly contaminated soil stockpiles, hotspots, and below grade soils will be excavated and subsequently
transported off-site for disposal. The soils will be excavated with an excavator/backhoe, screened to
removed debris, stabilized on-site (as necessary), and then loaded onto containers for off-site disposal.
The stabilization process will consist of spraying a chemical stabilizing agent (e.g., a phosphate-based
chelating compound), then working the soil with an excavator/backhoe to stabilize the leachable
contaminants and reduce Toxicity Characteristic Leaching Procedure (TCLP) concentrations to below
applicable hazardous waste thresholds. The chemical stabilizing agent binds the contaminant (i.e., lead)
to the soil and forms an insoluble compound, thereby rendering it unleachable. Stabilization is
performed by spraying the stabilizing agency into the stockpile, mixing the stockpile thoroughly with an
excavator, and re-spraying as necessary for covereage. Post-stabilization testing will be performed
where applicable to assess resulting TCLP concentrations.
Excavation and screening activities will be focused in the Exclusion Zone in the western and westcentral portions of the Site. Loading activities will occur on or near the concrete pad, in the southern
portion of the Site near Industrial Way.
To minimize fugitive dust, dust control measures will be implemented during all Site activities likely to
generate dust. Such activities are anticipated to include soil excavation, on-site soil movement,
screening, stabilization, and loading. During daily operations, dust abatement measures (i.e., water
spraying or misting) will be employed to minimize the spread of dust contaminants, and to reduce the
potential for exposure to Site workers and the adjacent community in accordance with the remediation
Air Monitoring Plan (AECOM, 2009).

Transportation and Off-Site Disposal
Contaminated soil and debris will be transported off-Site by truck or rail. The rail disposal option may not
be viable due to required infrastructure improvements to the track on-Site.
Trucks leaving the Site will be decontaminated as described below and will conform to the truck route
shown on the figure included in Attachment B. This route is as follows:

Start out going EAST on INDUSTRIAL WAY toward INDUSTRIAL DRIVE (0.0 mi)

INDUSTRIAL WAY toward INDUSTRIAL DRIVE (0.5 mi)

Turn RIGHT onto MILTON ST (0.1 mi)

Turn RIGHT onto MILTON ST/NEPONSET VALLEY PKWY (0.1 mi)

Turn RIGHT onto HYDE PARK AVE/NEPONSET VALLEY PKWY. Continue to follow NEPONSET
VALLEY PKWY (0.7 mi)

Turn SLIGHT RIGHT to stay on NEPONSET VALLEY PKWY (0.6 mi)

Turn RIGHT onto BLUE HILL AVE/MA-138. Continue to follow MA-138 S. (1.9 mi) to Interstate 93
All containers will be covered and decontaminated prior to leaving the Site.
It is estimated that, using 30-ton trucks, approximately 714 truckloads will need to be transported from
the Site and that due to the likely disposal location(s) in New Hampshire for Maine or soil transported via
truck, that this will be accomplished in 9 to 10 weeks, working from Monday to Friday only.
Should rail cars be used, we estimate that approximately 214 100-ton gondolas will be brought off-Site in
batches of approximately 13 rail cars each. All rail cars will be covered and decontaminated prior to
leaving the Site. It is anticipated that rail cars will be shipped to a landfill(s) in Virginia or Michigan, over
a period of 3 to 4 weeks, working from Monday to Friday only.

Vehicle Decontamination Procedures
Prior to exiting the Site, transport vehicles will be decontaminated via washing. This washing activity will
take place on a decontamination pad (decon pad) located adjacent to the concrete pad, or as close to it
as feasible. Heavy equipment may be dry decontaminated, if possible. It should be noted that, if
possible, clean areas/corridors that either eliminate or minimize any decontamination washing will be
utilized. Efforts will be made to unload, use and load transport equipment in a manner that prevents
contact of the vehicles with impacted materials and, therefore, decontamination will not be necessary.
4.1 Decon Pad Design
A decon pad will be constructed to decontaminate equipment and vehicles exiting the Site, such as
excavators, or support trucks that may have come into contact with contaminated soil. At a minimum,
equipment and/or vehicles that contact potentially contaminated soil will be washed down (or dry
decontaminated) prior to exiting the Site. A typical decon pad design is as follows:

The decon pad dimensions will be 50 feet (length) by 15 feet (width);

The pad will slope toward a center low point sump to allow for collection of decontamination
water;

The pad will be constructed of 60 mil high density polyethylene (HDPE) liner material overlain by
a geotextile, and a minimum of 12 inches of clean sub-angular stone will be back filled over the
HDPE liner and geotextile;

A 12-inch high containment berm constructed of clean sub-angular stone will be placed around
the perimeter of the decon pad; and

The pad will be equipped with 3-feet high splash guards dropped inside the bermed pad to
prevent over spray.
4.2 Decon Water
Equipment and vehicles exiting established the Site during contaminated soils remediation activities will
be washed down, as required, using a high pressure water and steam system.
Decon water will drain toward the center of the decon pad. A 6-inch diameter perforated HDPE pipe
(SDR 17 or equal) will be located at the low point of the pad which will collect and drain decon water into
a 55-gallon sump or equivalent.
Water collected in the sump will be pumped into a 5,000-gallon storage (poly) tank or equivalent.
Flexible hose and/or piping will serve as the connection between the decon pad sump and the poly tank.

4.3 Decon Water Disposal
Poly tanks that are at or near capacity will be transported to a fully operational, licensed facility that is in
compliance with all Federal, State, and local regulations which is capable of decon water recycling or
disposal.
AECOM will prepare all hazardous waste manifests and all other documentation in order to transport
and dispose of decon water. MBTA will be designated as generator and will sign all manifests.
Documentation certifying that all decon water was transported to, accepted, and disposed of, will be
submitted to MBTA. The documentation will include, but is not limited to the following:

A record of each load from the Site to the disposal/recycling facility, including all manifests, Bills
of Lading, and all other documentation as applicable.

All documentation for each load shall be tracked by the original manifest document number that
was assigned at the Site.
It should also be noted that decon water will not be transported off-site until all disposal/recycling facility
documentation has been reviewed and approved by MBTA or their representative.
Transportation of the decon water from the Site to the disposal/recycling facility will be in accordance
with all U.S. Department of Transportation (DOT), U.S. Environmental Protection Agency (EPA) and
MassDEP regulations. Decon water hauler(s) will be licensed in all states affected by the transport.
Chemical analyses shall be performed on behalf of the MBTA, as necessary, to fulfill any
disposal/recycling testing requirements of the approved facility. The decontamination water will be
sampled at the frequency specified by the disposal facility and for the parameters required for waste
acceptance at the facility. A copy of all chemical analyses results will be submitted to MBTA after
receipt of the laboratory report.
4.4 Decon Pad Disposal
Once contaminated soils excavation activities at the Site have been completed, the decon pad will be
disassembled and each component handled properly.
The stone base will be tested to determine the most appropriate end use or disposal method. The
HDPE liner will be pressure washed. It is anticipated that both materials will be reused and/or disposed
in a lined landfill. The geotextile will be properly disposed at a lined landfill.
4.5 Contamination Prevention
One of the most important aspects of decontamination is the prevention of contamination. Good
contamination prevention should minimize worker/adjacent resident exposure and help ensure valid
sample results by precluding cross-contamination. For heavy equipment, procedures for contamination
avoidance include limiting the surface area of equipment that comes into contact with contamination.

4.6 Disposal Procedures
Discarded materials, waste materials, field equipment and supplies will be handled to preclude the
potential for spreading contamination, creating a sanitary hazard, or causing litter to be left on site.
Potentially contaminated materials, e.g., clothing, gloves, etc., will be bagged or drummed with
appropriate labeling affixed as regulated, and disposed of and shipped with other hazardous materials.
Non-contaminated materials shall be collected, bagged, and disposed of as simple non-hazardous solid
waste.

Reporting
After screening and stabilization of TCLP-lead exceedence soil, the soil will be loaded using an
excavator/backhoe into DOT-approved covered trucks or rail cars for shipment and disposal at a licensed, outof-state lined landfill. Truck and rail transportation will be performed by a licensed hazardous waste hauler.
Soil will be shipped using Massachusetts Bills of Lading (BOLs), which will be stamped by the Licensed Site
Professional. Certified weight slips and original BOLs will be obtained from the disposal facility for inclusion in
the Phase IV Status Reports and/or Response Action Outcome (RAO) Statement.
Daily logs will be completed in which the time of shipment, estimated volume of material shipped, the vehicle
registration number and the transporter name is recorded on a Bill of Lading Log Sheet (BWSC 012B). A
summary report with the date of shipment, date of receipt at the facility, number of loads shipped, and total
daily tonnage values recorded will be developed on a weekly basis on a Bill of Lading Summary Form (BWSC
012C) . This report will be available at the Site.
