Board of Public Works Meeting Date: December 16, 2021
Jeff Lafleur, Superintendent
Solid Waste Department
Change Order #1 - Design and Permitting Services for Phase IIH, Stage 2 Landfill
To approve a change order to the contract with Sanborn Head and Associates Inc.
to prepare and submit a NHDES Type II Permit Modification, prepare plans,
specifications and bid documents, and perform bid-phase services for the
construction of the Phase III, Stage 2 lined landfill expansion in the amount not to
exceed $91,000. Funding through Department 168 Solid Waste; Fund: Bond;
Activity: Landfill Expansion Phase III & IV.
Sanborn Head and Associates scope of work
The Superintendent of the Solid Waste Department and the Director of Public
Works recommend that the City begin the process of designing and constructing
the Phase III, Stage 2 lined landfill expansion. This is the final phase of the lined
landfill expansion permitted by the New Hampshire Department of
Environmental Services (NHDES) in standard permit #DES-SW-SP-95-002
issued on June 26, 1995. The Phase III, Stage 2 landfill will be a vertical
expansion of the existing Phase III, Stage 1 landfill. It will provide an additional
270,000 cubic yards of waste capacity and an additional two years of landfill life
expectancy. Work to be performed under this change order includes preparation
of a NHDES Type II Permit Modification application, construction plans,
specifications and bid documents, and performing bid-phase services.
The additional airspace is needed given the constraints and concerns regarding the
permit approval process with NHDES. This process is a lengthy one that we
anticipate will take a long period of time to complete which is why we wish to be
proactive by moving forward now. It is recommended that this Phase be
constructed within the next two years to ensure the landfill has adequate disposal
capacity available.
