Task4 Annual Financial Assurance Update
The NHDES Rules require landfill owners to submit financial assurance updates to NHDES
every third calendar year in order to demonstrate that financial assurance for closure and
long-term monitoring and maintenance (LTMM) is provided for the Four Hills Landfill
{(Env-Sw 1400}. During the years in which a submittal to NHDES is not required, an
updated closure cost estimate is required to be prepared and kept for the facility's records.
Since the City last submitted an update to NHDES in March 2018, the next submittal to
NHDES will be required in March 2021. Updates prepared during FY 2020 and 2022
should be kept for the facility’s records.
This financial assurance demonstration includes preparation of opinions of closure and
post-closure cost for the currently permitted areas (Phases I, II, and III) and calculations to
demonstrate that the City is setting aside funds sufficient for future closure and post-
closure needs.
Sanborn Head will prepare the opinions of cost using the required NHDES forms based on
the permitted closure plan, currently available average unit costs for similar projects,
current costs for monitoring services, published construction cost estimating guides, and
our engineering judgment. We will estimate the remaining life of Phases I, II, and III based
on the latest survey update and prepare sinking fund calculations using account balances
provided to us, actual waste tonnage received at the Four Hills Landfill, and the projected
waste tonnage for the remaining estimated life of Phase I, II and III. The calculations will
demonstrate that the balances for the closure and LTMM accounts are consistent with what
was projected or provide amounts per ton that should be set aside going forward to
provide sufficient funds at the expected date of closure.
Sanborn Head will prepare a letter, addressed to the City, that documents our evaluation,
which will include NHDES Cost Estimate Forms for landfill closure and post-closure care,
and sinking fund calculations.
Task5 General Engineering Services
Sanborn Head’s services under this task will be performed at the City’s request and involve
