Change Order #1 — Design and Permitting Services for the Phase IV Landfill
To approve a change order to the contract with Sanborn Head and Associates Inc.
to complete the process of permitting the Phase IV lined landfill with NHDES,
prepare construction plans, specifications, and bid documents, and perform bid
phase services in the amount not to exceed $210,000. Funding will be through
Department 168 Solid Waste; Fund: Bond; Activity: Landfill Expansion Phase II]
& 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 complete the process of permitting the
conceptual Phase IV lined landfill with the New Hampshire Department of
Environmental Services (NHDES), prepare construction plans, specifications and
bid documents, and budget for bid-phase services. The Phase IV landfill is to be
sited at the Four Hills facility in the valley formed by the closed MSW landfill
and the Phase I lined landfill. It is projected to cover approximately 27 acres, will
provide the City with an estimated waste disposal capacity of 2.6 million cubic
yards, and extend the life of the landfill by about 30 years. Initial permitting work
for Phase IV began in 2017 with a budget of $300,000. At that time it was
estimated that the total permitting cost would be approximately $500,000 and take
several years to complete. Although the disposal capacity of this proposed phase
will not be needed for many years, it is recommended that the City complete the
permitting process now to avoid potential future changes to solid waste
regulations that could prohibit further landfill expansion.
