Kalispell Biosolids Treatment
and Disposal
April 2, 20A
The Cityali anced
Wastewater Treatment. lant
(AWWTP) manages biosolids
generated from.wastewater
treatment. Approximately 70% of
the City's biosolids are
composted at Glacier Gold Com-
posting (GGC) and the remain-
ing 30% are disposed at the
Flathead County Landfill (Land-
fill). Through a 2024 Preliminary
Engineering Report (PER), the
City evaluated alternatives for
future biosolids management.
Action is needed because
GGC is closing its Olney, MT
composting facility in Fall 2026,
the Landfill cannot accept more L
biosolids at the moisture content
currently produced (averaging of
15% total solids), and emerging
contaminant regulations may
present challenges for long-term
land application of biosolids.
The City selected a dewatering
and Landfill disposal option to
safely and effectively manage its
biosolids in a cost-effective
manner. The construction project
'comprises installing a new
jiosolids dewatering volute
press and associated equipment
and removal of the existing belt
filter press system. All work will
be within the existing AWWTP
facility. The project will allow
the AWWTP to produce biosolids
at a moisture content (18-20%)
that will allow safe disposal of
all the material at the Landfill,
Protecting public health and the
environment. The dewatering
project provides redundancy for
equipment in the AWWTP and is
a prerequisite if additional
biosolids processing such as
drying is required in the future.
Pursuant to ARM 17.40.318, the
Department has concluded that
the proposed project meets
the Categorical Exclusion criteria
of the National Environmental
Policy Act (NEPA) and the
Montana Environmental Policy
Act (MEPA). The Categorical
Exclusion may be revoked if the
