REPORT TO: Honorable Mayor and City Commission
FROM: Debbie Arkell, Director of Public Services
Tom Adams, Water Reclamation Facility Superintendent
SUBJECT: Interlocal Agreement for Biosolids and Green Waste Disposal and
Management for Beneficial Reuse with Gallatin Solid Waste Management
District Board
MEETING DATE: August 8, 2011
AGENDA ITEM TYPE: Consent
RECOMMENDATION: Authorize City Manager to Sign Interlocal Agreement for Biosolids
and Green Waste Disposal and Management for Beneficial Reuse with Gallatin Solid Waste
Management District Board for a five year period
BACKGROUND: The current Water Reclamation Facility produces a liquid effluent that is
currently land applied on farm fields. The new Facility will produce a dewatered sludge cake
which is more labor intensive and expensive to land apply. However, the cake is an ideal
component for making compost. Water Reclamation Facility Superintendent Tom Adams
explored five options for the disposal of the effluent produced from the plant:
1. Status Quo. Stay in the liquid effluent mode ($395/dry ton)
2. Make dewatered cake and apply to agriculture land in the summer; and remain in the
liquid effluent mode during the winter and apply the liquid sludge to farm fields in
the summer ($284/dry ton, plus tipping fee)
3. Make and apply dewatered cake to agriculture land in the summer and fall, and haul
the cake to the Logan landfill in the winter and spring ($135/dry ton plus tipping fee)
4. Make dewatered cake and haul to Logan landfill year round ($106/dry ton plus
tipping fee)
5. Make dewatered cake and contract for composting services ($178/dry ton plus tipping
fee)
Mr. Adams worked with Martin Bey, Manager of the Gallatin Solid Waste District, to investigate
the feasibility of the District starting an on-site composting program. The District will need
approximately 15,000 cubic yards of top soil to complete the topsoil requirement for the final
closure of the Logan Landfill’s cell #2, which will take place over the next two years. Creating
26
this topsoil through an on-site composting program will save the District a considerable amount
of money and it will allow the dewatered cake to be used in an environmentally sound way.
In February 2011, the Gallatin Solid Waste District Board voted to accept the dewatered cake
from the plant. Mr. Bey has since attended compost production training and received the
necessary permit from the Montana Department of Environmental Quality to do on-site
composting at the Logan Landfill. Mr. Bey calculated it will cost the District approximately
$6.70 per ton to operate the composting facility. At their July 27, 2011 meeting, the Board voted
to enter into the subject Interlocal Agreement. As the City’s representative member, I abstained
from this vote.
Wood chips and other green waste that are currently disposed of at the Bozeman Convenience
Site, as well as that produced by the City’s Forestry Division, will be mixed in with the
dewatered cake prior to delivery to the Logan Landfill whenever possible. The cost to the City
to dispose of this mixed product will be 25% of the municipal solid waste fee in effect at the time
of disposal. Currently, the fee will be $6.75 per ton of dewatered cake. The weight of the wood
chips will be deducted from the load weight. This product will then be deposited into the
compost area at the Logan Landfill.
If wood chips or other green waste is not available to be mixed in with the dewatered cake, and
there is no similar product available at the Logan Landfill, the dewatered cake will be deposited
in the lined cell, and we will be charge the municipal solid waste fee in effect at the time of
disposal. Currently, that fee is $27.00 per ton.
Staff will continue to work closely with the Gallatin Solid Waste District to ensure the program
operates as smoothly as possible.
UNRESOLVED ISSUES: None identified
ALTERNATIVES: As suggested by the Commission
FISCAL EFFECTS: Mr. Adams has estimated 2,920 tons of dewatered cake will be disposed
of annually, but until operations are underway, this is only an estimate. The total estimated
annual cost of this option including labor, fuel, depreciation and repairs is $106/dry ton plus the
Logan Landfill tipping fee. At $27/ton for the 2,920 ton, this would add $78,840. At $6.75/ton,
this would add $19,710. The Facility’s FY12 pending budget includes funds for dewatered cake
disposal. The cost of the equipment to make and haul dewatered sludge is already included in
the cost of the Water Reclamation Facility construction budget.
