City of Nashua RFP 0929-041221
Air Quality and Landfill Gas Testing
School sites under EPA’s Superfund program in the 1990s. TRC was the prime contractor for the EPA and
oversaw 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 effectiveness of the
implemented corrective actions.
The City of Nashua and TRC have worked together on several projects. Two such projects were the
combined sewer outflow improvement projects 004 and 005 off of Bridge Street in 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 Labyrinth along Main Street in Nashua.
Town of Manchester: Landfill Engineering Services for Manchester Sanitary Landfill - Manchester, CT
TRC was initially retained by the Town of Manchester to perform air quality assessments of potential Title V
sources owned and operated by the Town. TRC conducted site visits to evaluate each air emission premise
and to develop facility-specific permitting strategies that would minimize the need for Title V air permits
where possible. If identified as subject to these requirements, TRC developed the appropriate permit
application documents for agency review and approval.
After completion of this initial project, TRC assisted the Town with negotiations to finalize the construction
of, and operating air permits for, the Manchester Landfill gas odor control system. After construction, TRC
was retained to conduct the initial performance test of the landfill gas flare as required by the construction
permit conditions. TRC also conducted the required landfill gas sampling, surface monitoring for methane,
and a fugitive dust survey/roadway silt sampling. The landfill gas characterization sampling effort enabled
the Town to demonstrate that the non-methane organic compound (NMOC) emission rate was less than
Subpart WWW applicability thresholds and minimize long-term reporting requirements.
Currently, TRC provides continuous air compliance support services not only to the landfill, but to the Town’s
landfill premises, which includes the sewage treatment plant, highway department, fleet maintenance
operations, and the BOE Grange building. TRC is also responsible for addressing the conditions of the existing
Title V Operating Permit as well as the NSR air permit for the landfill premises to ensure continuous compliant
operations. This scope of services includes several Title V reporting requirements, Subpart WWW annual
reports, annual NSR permit reporting, NSR permit requirements for rolling 12-month emission and usage
records, NOx RACT recordkeeping, annual emissions statement submittals, quarterly methane surface
monitoring, and monthly wellhead monitoring. In addition, TRC currently assists Manchester with the
monitoring, recordkeeping and reporting requirements of 40 CFR Part 98 — Mandatory Greenhouse Gas
Reporting, initiated in 2010, which includes frequent methane measurements of the raw LFG from the
landfill.
