DESCRIPTION OF PROJECT
The construction of the new Vehicle Maintenance Shop at the Lower Yards on Rouse Avenue in FY10/FY11 was Phase I in
expanding and improving our ability to service equipment, store vehicles, and provide work space for Public Works, Parks, and
Facilitiy services. Questions remain about the long-term plan for construction, location, and expansion for: Streets, Sign & Signal,
Forestry, Water/Sewer Operations, Solid Waste Collection & Recycling, Facilities, and Parks & Cemetery departments. This
project would develop a master plan. In scheduling this project, we are recommending waiting until after the Vehicle Maintenance
Division is relocated to its new shop and the interior improvements are made to the Shop at Rouse and Tamarack Street for the
remaining divisions.

DESCRIPTION OF PROJECT
Develop a comprehensive, multi-year watershed study and computer model for the East Gallatin River which would enable the
City and DEQ to better determine stream load allocations and develop a more scientifically valid TMDL for the river segment we
discharge to. This will require annual field sample collection, laboratory analytical work and detailed computer modeling using
calibrated data. This multi-year study would consist of $45,000 in consulting and computer modeling fees for at least two fiscal
years (FY14 and FY15) and stream sampling/lab fees of $15,000 each year. Craig recommends we should be prepared to continue
this work beyond FY15 as necessary.
ALTERNATIVES CONSIDERED
Not undertake this work and risk having to accept the TMDL and waste load allocations the DEQ has proposed in their original
draft documents. This decision could greatly limit our ability to appeal future nutrient limitations and could result in non-
compliance.
ADVANTAGES OF APPROVAL
This watershed study will greatly enhance the City’s understand of our impact on the East Gallatin River and enable us to more successfully
negotiate future permit limitations with the DEQ.
ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED
None, unless additional stream sampling is desired in subsequent years.

DESIGN PHASE II - WRF PLANT IMPROVEMENTS
FY16 FY17 Unscheduled
$5,230,000
DESCRIPTION OF PROJECT
In January 2006 Morrison & Maierle Consulting Engineers completed a comprehensive Wastewater Facilities Plan. The plan
recommends the City proceed with a 3-phased project schedule that includes the construction of the new Water Reclamation
Facility (WRF), capable of handling our increased flows while also reducing the amount of Total Nitrogen discharged to the East
Gallatin River. Phase two is expected to include one new primary clarifier, more BNR reactor basins, clarifiers, tertiary
membrane filtration, liquid sludge storage tanks, anaerobic digestion, and an effluent re-use pumping station. The capacity
expanding (impact fee eligible) elements are: bioreactor basins, clarifiers, and pumping station. It is possible that this phase of the
project could be further divided into phase 2A and phase 2B, if necessary.
ALTERNATIVES CONSIDERED
A variety of treatment technologies and alternatives are presented in the January 2006 Wastewater Facilities Plan.
ADVANTAGES OF APPROVAL
Major capital expansion of the Bozeman WRF will enable the City to meet its estimated demand for wastewater services and still produce a high
quality effluent that is in full compliance with the City’s MPDES discharge permit. Expansion of the Bozeman WRF is consistent with the City’s
long-term need to accommodate rapid growth and economic development in the Gallatin Valley.
ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED
Annual Operating & Maintenance Costs: no estimates at this time.
FUNDING SOURCES
Total Design Cost: $5,230,000. We estimate the majority of the project costs are related to regulation and maintenance issues and would be
borne by the Utility Fund. Half are related to capacity expansion, and would be borne by Impact Fees. 50% Wastewater Fund, 50% Wastewater

FY16 FY17 Unscheduled
$350,000
DESCRIPTION OF PROJECT
Consistent with the goals of the City’s Climate Action Plan & Sustainability Programs, the Bozeman WRF staff and Public
Works Director recommend we move forward with our proposed investigation and installation of a methane recovery and co-
generation system. This system will produce an average of 175 kW of electricity and 974,000 BTU/hour of thermal output using a
generator powered entirely by WRF digester gas. This project has the potential to save the City at least $180,000 in electricity
costs and substantially lower the carbon footprint of the new Bozeman WRF. This project would be implemented in 3 phases
including (1) a feasibility / cost effectiveness study, (2) project engineering / design and (3) the purchase and installation of
appropriate technology for the co-generation of electricity at the Bozeman WRF. Year 1: Project Feasibility Study. Year 2: Project
Engineering Design - $350,000. Year 3: Equipment Purchase and Installation - $2,200,000.
ALTERNATIVES CONSIDERED
Continue to flare our digester methane gas. Micro-turbines and fuel-cells have been analysed and continue to be possible
alternative energy recovery technologies for this project. Our research to date suggests the most proven technology currently
available to help us accomplish our energy recovery goals is likely to be a GE Jenbacher internal combustion engine and heat
recovery system.ADVANTAGES OF APPROVAL
Current plant waste gases will be captured and utilized to reduce plant operating costs. The project has an estimated net dollar savings of
$230,000 per year. It supports the City's Municipal Climate Action Plan goals.
ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED
Once construction is funded, this project results in an estimated net dollar SAVINGS of $230,000/year.

ADVANTAGES OF APPROVAL
The second screw press would provide needed redundancy if a screw press breaks down. It would provide extra sludge processing capacity
now and for future needs.
ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED
If used to increase processing capacity, the extra operating costs would include electricity, polymer use and additional cake

#3 PERFORATED SCREEN & WASHER COMPACTOR
FY16
$140,000
FY17 Unscheduled
DESCRIPTION OF PROJECT
Extensive Engineering will be needed to install an additional influent huber screen in head works building because of limited space.
Additional screening capacity is needed because during a storm event this summer the influent flow meter pegged out over 15
mgd.
ALTERNATIVES CONSIDERED
Do nothing.
ADVANTAGES OF APPROVAL
THE TWO EXISTING SCREENS ARE RUNNING MOST OF THE YEAR SO IF ONE GOES DOWN THERE IS NO REDUNDANCY. HAVING
A THIRD SCREEN WOULD PREVENT A HIGH FLOW EVENT FROM OVER FLOWING THE BYPASS CHANNEL INFLUENT GATE. THIS
UNSCREENED FLOW CONTAINS MATERIAL THAT CAN PLUS PIPING AND PUMPS CAUSING DAMAGE & EXTRA MAINTENANCE.
ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED
IF PLACED IN A TWO SCREEN ROTATION, THE ONLY EXTRA COSTS WOULD BE AN ANNUAL INSPECTION WITH
PARTS REPLACEMENT PLUS CLEANING OF THE SCREEN & CHANNEL IT IS IN. IF USED TO INCREASE CAPACITY,
EXTRA ELECTRICITY WOULD BE USED BUT LESS CHANNEL CLEANING WOULD NEED TO BE PERFORMED.

ADVANTAGES OF APPROVAL
COVERING THE PRIMARY CLARIFIERS WILL ALLOW ODOR CONTROL & ELIMINATE CLEANING & PAINTING. CLEANING &
PAINTING OF ALL RAILINGS AND CATWALKS IS AN ON-GOING MAINTENANCE ISSUE TO REMOVE GREASE & DROPPINGS
DEPOSITED BY BIRDS. COVERS ON PRIMARY CLARIFIERS WOULD ALLOW SOME CLARIFIERS NOT TO BE USED DURING THE
WINTER ALLOWING MORE NEEDED CARBON TO ENTER THE BIO-TRAINS.

METHANE COGENERATION PROJECT CONSTRUCTION
FY16 FY17 Unscheduled
$2,200,000
DESCRIPTION OF PROJECT
Consistent with the goals of the City’s Climate Action Plan & Sustainability Programs, the Bozeman WRF staff and Public
Works Director recommend we move forward with our proposed investigation and installation of a methane recovery and co-
generation system. This system will produce an average of 175 kW of electricity and 974,000 BTU/hour of thermal output using a
generator powered entirely by WRF digester gas. This project has the potential to save the City at least $180,000 in electricity
costs and substantially lower the carbon footprint of the new Bozeman WRF. This project would be implemented in 3 phases
including (1) a feasibility / cost effectiveness study, (2) project engineering / design and (3) the purchase and installation of
appropriate technology for the co-generation of electricity at the Bozeman WRF. Year 1: Project Feasibility Study. Year 2: Project
Engineering Design - $350,000. Year 3: Equipment Purchase and Installation - $2,200,000.
ALTERNATIVES CONSIDERED
Continue to flare our digester methane gas. Micro-turbines and fuel-cells have been analyzed and continue to be possible
alternative energy recovery technologies for this project. Our research to date suggests the most proven technology currently
available to help us accomplish our energy recovery goals is likely to be a GE Jenbacher internal combustion engine and heat
recovery system.ADVANTAGES OF APPROVAL
Current plant waste gases will be captured and utilized to reduce plant operating costs. The project has an estimated net dollar savings of
$230,000 per year. It supports the City's Municipal Climate Action Plan goals.
ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED
Once construction is funded, this project results in an estimated net dollar SAVINGS of $230,000/year
