To approve a contract with Sanborn Head and Associates Inc. to prepare and

construction of the Phase ITI lined landfill expansion in the amount not to exceed
$200,000. Funding through Department 168 Solid Waste; Fund: Bond; Activity:
Landfill Expansion Phase III & IV
Sole Source Memo, 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 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 landfill will be located adjacent to the southern boundary of
the Phase II landfill. It is anticipated to cover approximately 9.4 acres with an
estimated disposal capacity of 1.5 million cubic yards and a life expectancy of 10-
plus years. Work to be performed under this contract includes preparation of a
NHDES Type II Permit Modification application, construction plans and
specifications, an Alteration of Terrain (AoT) permit application, and an
evaluation of engineering alternatives to identify opportunities for improved
construction and operational methods and cost savings. The additional landfill air
space is not needed for several years; however, it is recommended that this Phase
be constructed within the next three years to ensure disposal capacity is available
when capacity in the Phase I/II landfill is exhausted.
