Spring 2017 Landfill Gas Collection System Expansion
To approve a contract with Charter Contracting Company LLC of Boston, MA to
construct an expansion of the landfill gas collection system in the Phase I/II landfill in the
amount of $298,385.00. Funding will be through Department 168 Solid Waste; Fund:
Bond; Activity: Landfill Gas Expansion FY17
The City issued an Invitation to Bid for construction of an expansion and
modification to the landfill gas collection system in the Phase I/II landfill.
Periodic expansions of the gas collection system are required as the landfill
continues to be filled with waste. The Solid Waste Department’s engineering
firm, Sanborn Head and Associates, Inc. (SHA) prepared a construction design to
install six (6) new horizontal gas collection wells, landfill gas condensate
pumping systems in up to ten (10) of the existing vertical collection wells, and
Drain tube surface collection on selected areas of the landfill. This expansion of
the gas collection system is required to control odors, mitigate fugitive methane
surface emissions and comply with the NHDES approved Operating Plan —
Phase II Secure Landfill Expansion and the Landfill Gas Collection System
Enhanced Monitoring Protocol/Standard Operating Procedures (EMP/SOP).
The City received bids from six (6) qualified vendors. Based on the low bid and
qualifications of Charter Contracting Company LLC it is the recommendation of the
Superintendent of Solid Waste to accept Charter Contracting Company LLC as the
vendor to perform the work listed above.
