Landfill Closure and Postclosure Care Costs
State and Federal laws and regulations require the City to place a final cover on its landfill site
when it stops accepting waste and to perform certain maintenance and monitoring functions
at the site for thirty years after closure. Although closure and postclosure care costs will be
paid only near or after the date that the landfill stops accepting waste, the City reports a
portion of these closure and postclosure care costs as a liability in the financial statements
in each period based on landfill capacity used as of each balance sheet date.
The $9,840,185 reported as landfill closure and postclosure care liability at June 30, 2021
comprises $757,900 of post closure care cost for the Nashua Four Hills unlined landfill and
$9,082,285 in closure, and post closure costs for the Nashua Four Hills Phase I, Phase I]
and Phase II] lined expansion landfills. The recognition of these costs is based on annual
statutorily required engineering estimates. Waste filling operations in the Phase II lined
expansion landfill began in November 2009. The combined landfills are conservatively
estimated to have an operational life of 8 years and remaining capacity is estimated to be
29%. The City will recognize the remaining estimated cost of closure and post closure care
of the lined landfill as the remaining capacity is filled. The actual life of the landfill may
be longer due to recycling efforts and actual costs may be higher due to inflation, changes
in technology or changes in landfill laws and regulations.
The City is required by State and Federal laws and regulations to make annual contributions
to an account held by the City to finance closure and post closure costs of the municipal
solid waste landfill. As of June 30, 2021, the City has cash on deposit with a balance of
$6,957,676 restricted for closure and post closure costs.
Deferred Inflows of Resources

applicable to future reporting periods. Deferred inflows of resources have a negative effect
on net position, similar to liabilities. Deferred inflows of resources related to pension and
OPEB will be recognized as expense in future years and is more fully described in the
corresponding pension and OPEB notes.
