D. Similar Experience
TRC has worked on the Shady Lane Landfill and Searles School
sites under EPA’s Superfund program in the 1990s. TRC was
the prime contractor for the EPA and over saw the
construction of the new cap in 1994. TRC subsequently
followed up with several years of monitoring under the EPA
contract for the new cap and the school confirming the
effectiveness of the implemented corrective actions.

The City of Nashua and TRC has more recently worked
together on several other projects. Two such projects were the combined sewer outflow
improvement projects 004 and 005 off of Bridge Street Nashua with Hazen and Sawyer. TRC
provided environmental, geotechnical, and permitting support for these two important projects
along the Merrimack River. The work also included extensive coordination with various federal,
state, and local agencies as the work included tunneling under an Army Corps of Engineer's
asbestos-containing flood control dike. TRC also supported the City of Nashua on one of their
previous EPA Brownfields Assessment grant programs. TRC provided crucial environmental and
remediation support to facilitate the development of the Rotary Common Park and La byrinth
along Main Street in Nashua.

In addition, TRC has worked with Eversource on several other projects in Nashua that involved
the upgrading of the electric grid. New substations and power poles were ail installed in known
asbestos contaminated areas. TRC also worked with a private developer in Nashua to help
support a proposed expansive mixed-used redevelopment along the Merrimack River.

TRC has been working on all aspects of landfill gas systems for numerous clients over many
years. Types of landfill gas control systems that TRC has worked with include: ground flares,
gas engines and gas turbines.

Energy Power Partners (EPP)

EPP owns and operates many landfill sites that collects landfill gas and burns it in engines to
generate electricity. TRC has tested both the landfill gas fueling the engines and the emissions
generated by the engines. In addition to the engines these sites also operate flares as emission
controls if the engines fail.

Some of the EPP landfill sites that TRC has worked at include:
NH — Nashua

VT ~ Moretown

PA — Blue Ridge and Cumberland County Landfill

NJ — Vineland, and Pennsauken

Fortistar Methane Group (FMG)
Fortistar owns and operates many closed landfills and specializes in renewable power. Fortistar
use the landfill gas to fuel both engines and turbines to generate electricity. They have also

converted many landfills to solar farms. TRC has tested the landfill gas and emissions from the
engines and turbines.

Some of the FMG facilities that TRC has worked at include:
MA — Taunton, Halifax, New Bedford, Brockton

VA — Richmond

NY — Albany

Casella

Casella is recovering landfill gas so it can be used as an energy
resource. Casella and its partners are now producing roughly 25
megawatts per hour of clean energy at five of the company's
landfills. This clean energy is enough to power approximately 25,000 homes and results in
substantial reductions in greenhouse gas emissions. To capture the methane gas before it can
escape to the air, a series of wells is connected to a powerful vacuum which actively pulls it to
the power generation plants where it is converted to electricity.

The Casella facility that TRC has worked at is:
NY — Clinton County

TransCanada Hydro Northeast, Former Landfill Assessment and Closure —
Wilmington, VT (Senior Geologist)

Mr. Stapleton managed the assessment and closure of former solid waste landfill.
Assessment of groundwater impact was conducting utilizing Membrane Interface
Probe technology to rapidly locate volatile organic compounds in groundwater and
optimize locating permanent monitoring wells. Upon presenting a case that the

closed with a simple soil and riprap cap.

City of Lowell, Grand Manor Condominiums — Lowell, MA (Project Manager)
Mr. Stapleton is the Project Manager for the Grand Manor Condominiums project.
This project involves the assessment of a parcel of land which was formerly a —
municipal dump that was subsequently covered over with soil in 1955. Two
generations later the parcel was redeveloped for use as a condominium building.
indoor air sampling has been conducted as part of a vapor intrusion assessment
and an assessment of soil and groundwater contamination has been completed.
Mitigation of a possible vapor intrusion pathway from the landfill is a major portion of
the current scope of work. Management duties include proposal generation,
budgeting, generation and submittal of MCP reports and management of TRC
engineers, geologists, and risk assessors.
