Bonner Data Center
Update 6/12/2026:
Missoula County planning staff have reviewed another application from Krambu and deemed it insufficient. The latest application and letter from the County are available under the Documents tab to the right. Krambu will need to submit a complete application before a hearing with the Missoula Consolidated Land Use Board can be scheduled.
The Bonner Data Center project developer is continuing to finalize materials for presentation to the Missoula County Consolidated Land Use Board (MCCLUB). At this time, the public hearing schedule is to be determined, pending receipt of a complete application.
You can sign up to follow this project at the right-hand side on this page. When the new date is determined for the MCCLUB public hearing, project followers and commenters will receive an email.
This project will be reviewed by the Missoula County Consolidated Land Use Board (MCCLUB). This land use board holds their public hearing meetings on the first Wednesday of the month at 6 p.m. in the Sophie Moiese room of the Missoula County Courthouse. There may occasionally be a second meeting in the month, which will usually be the third Wednesday. There will be prior notice. These meetings are always open to the public.
The meeting agenda and related documents will be published on the Consolidated Land Use Board page
Project Overview
Missoula County is reviewing a proposed data center at 9314 Bonner Miller Road as a Special Exception described in Section 11.6.D. of the Missoula County Zoning Regulations. The property is zoned for heavy industrial use.
The proposal involves reusing a portion of the former mill building — commonly referred to as the planer building — for a high-performance computing (HPC) data center. This means most of the development would occur inside the existing structure, with no major expansion of the building footprint. Interior improvements would include constructing specialized rooms to house computer servers and supporting equipment.
The proposed data center would operate continuously, 24 hours a day, seven days per week, with minimal on-site staffing and relatively limited vehicle traffic associated primarily with maintenance and service visits.
The initial phase of the facility is expected to use approximately 7 megawatts (MW) of electrical power, with the potential to expand over time to utilize up to 29 MW, which is the estimated capacity currently available at the site.

- This project will be reviewed by the Missoula County Consolidated Land Use Board (MCCLUB). This land use board holds their public hearing meetings on the first Wednesday of the month at 6 p.m. in the Sophie Moiese room of the Missoula County Courthouse. There may occasionally be a second meeting in the month, which will usually be the third Wednesday. There will be prior notice. These meetings are always open to the public.
What is being reviewed in this project proposal?
The Special Exception review is required when the use, because of location, scale, required infrastructure or other potential impacts, requires a special degree of consideration and control to ensure such uses are consistent and compatible with the overall community character and whether potential impacts can be avoided or mitigated.
This page has been updated to reflect revised staff analysis of the scope of review. The Missoula County Consolidated Land Use Board (MCCLUB) must not approve a special exception unless and until they find the project application demonstrates all of the following:
The proposed use or development will be compatible with and will not substantially injure the value of adjoining property.
The proposed use preserves the character of the district, and the property is suitable for the proposed use (e.g. can meet the bulk and dimensional standards without requiring a variance).
The proposed use promotes the purpose and intent of the TIF Special District, where appropriate.
Substitute or additional design standards will preserve and protect the area’s architectural and aesthetic qualities.
In reviewing a Special Exception application MCCLUB shall give due consideration to the following:
a) Access, traffic, parking demand, non-motorized transportation and onsite vehicle circulation
b) Dedication and development of streets, rights of way, and public use areas, such as adjoining sidewalks
c) Impacts on or of public and private utilities or services
d) Proposed siting of any new structures necessary to accommodate the use and their relationship to adjoining and surrounding properties
e) Recreation opportunities and open lands available to serve the use
f) Natural resource protections
g) Landscaping and screening requirements
h) Signage and street lighting
i) Noise, vibration, outdoor lighting and other on and offsite impacts from the use
j) Frequency of use and hours of operation
k) Area of land necessary and adequacy of the site to accommodate the use and meet the intent of the district and character of the neighborhood
l) How the proposed use addresses the purpose of the TIF Special District intended to attract, retain, grow and develop secondary value-adding industries
m) Any other unique or relevant circumstances related to the property.
The burden to demonstrate compliance with these criteria falls to the applicant, not the County or MCCLUB.
Reasonable and appropriate conditions may be required to ensure that any potentially injurious effect of the Special Exception on adjoining properties, the character of the neighborhood, the purpose and intent of the TIF Special District, or the health, safety and general welfare of the community will be minimized. Conditions much be based on the criteria for review.
Zoning compliance permit
If a special exception is approved, the developers must apply for a zoning compliance permit. The permit application must demonstrate compliance with the County's data center zoning regulations, including requirements for new renewable energy and e-waste recycling. Zoning compliance permits are subject to administrative review and do not go through public hearing process.

I am a resident of Missoula County and I oppose the approval of the Krambu Data Center project.
These tech companies are trying to fool us all into believing that we can't do things that humans have done for all of time. They want us to think that we can't create our own art, we can't compose our own correspondence, and we can't form our own opinions.
Do not approve this project. The damage that this center would do to our environment is not worth it. Write your own damn emails.
I find it ridiculous and ironic that this data center could be built right next to a park that has a plaque about how we had to restore a source of water that housed animals sacred to Montana tribes, and there is still consideration to use taxpayer money to build something that would be a catastrophic waste of water (I know university professors who can provide research for that fact as if you need it). Do not waste money on this stupid project.
I say no to the data center in Bonner. It’s an energy suck and a water suck. The interior West is already struggling with drought. Putting something like that here in Montana is insane.
I write to oppose the proposed Krambu Data Center as a resident of western Montana, for the impacts that will affect western Montana. Our rivers are ours, all of ours, to take care of and protect. Our wildlife are ours, all of ours, to take care of and protect. Our neighbors, and their neighbors our ours, to take care of and protect.
This proposed data center threatens thermal contamination of the wild Blackfoot river, which is already increasingly fragile with the warming planet. It promises a 24-hour noise factor that not only will affect the human population of Bonner, but also its wildlife populations. We don't need the robots to forge our thoughts, to draft our emails, to create fake music and images. We are humans with imaginations and a love for our planet. These conveniences are a distraction from the vile mass surveillance and war machines that these data centers support. Not on our watch and not on our dime!
Please, please dont do this. We dont need and we do not want a data center in Missoula, or Montana or anywhere else . I am from Argentina and I have read that another AI mega data center is planned for Patagonia in 2026-2027 by Sur Energy and partners. We dont need any of these.
We do not need or want a data center here using our resources!
NO, NO, NO, A thousand times no. Our land, water, and other natural resources should not be sold to enrich selfish, greedy carpetbaggers, especially for the advancement of AI, which poses its own existential threat to humanity. There is virtually no lasting benefit to Missoula and we simply cannot allow ourselves to be used in this way. Not here! Not anywhere as far as I'm concerned
AI Data centers are evil. They are a betrayal of Humanity and biological life. Please try to look past the myopic short-term timelines of greed, seductive power and economic gain. AI will help to enable the emergence of Autonomous Industrial Technology - a system of production that will be vastly more powerful than humans or biological life.
Autonomous Industrial Technology is a polymaterial multiscale system of precision mass production that is being created by human beings but will ultimately evolve and grow beyond human control and will displace the photosynthetic biochemical platform of production from the planet.
Think it's science fiction? Think again. Think about where things will be 50 years, 100 years or 200 years from now. Expand your understanding of science, technology and the growth of autonomous industrial production. The fate of biological life depends on people with the intelligence, wisdom and heart to care about the future and act to stop this existential threat.
Your descendants will thank you for your courage and wisdom.
As a 4th generation Montanan who has loved growing up and living here for the 20 out of 33 years of my life, i 100% wholeheartedly suggest that this operation is brought to a complete stop, and forgotten about..
Missoula has already seen an astronomical amount of development in the past decade, so much so that the infrastructure is having major issues supporting the increased volume of new infrastructure and population growth. There's already too much going on, and you want to add a massive operation that has a huge chance of destroying the waters and way of life for many who live and visit here? Doesn't make sense to me, doesn't make sense to any local, and it generally just doesn't make sense at all. The only sense it makes are to the people whose pockets will be lined from the result of this monster of an operation starting up; and those people are not locals or true Missoulians. If we let this one thing happen, that's going to open another door for something else which will be detrimental to the community to try to squeeze its way in here. These big developments in MT need to come to STOP; because at this rate Montana isn't going to be Montana in the next 10 years. THEN THERE WILL BE NO. LAST. BEST. PLACE.
TO GO TO...
My concerns regarding the 9341 Bonner Mill Rd data center application are twofold - electricity demands and pollution
1) Will the consumption of electricity proposed IN THE LONG TERM have any impact on the pricing of electricity for the greater Missoula area ratepayers?
If so, can we include a mechanism to offset any related electricity rate increases at any time inthe future?
For example, can we include a mechanism to keep the size of the energy load at the current amount requested in the application? Requests for increase in size of electrical load should AUTOMATICALLY result in a new application process to ensure that the community is never overwhelmed by the growth demands of this center.

Will any noise, light, dust, air, goundwater pollution, etc generated be kept well below the newest standards applicable for all adresses in the community?
This should require a complete environmenral impact study, not merely an environmental assessment, before any decision is made consistent with Montana's constitutional clean and healthful environment mandate. The EIS should encompass air, water, energy consumption and soil impact; effects on area flora and fauna; and noise. Failure to require a full EIS competently done will likely trigger a costly successful lawsuit against any governmental body which approves the center and jack up liability coverage rates substantially.
Hard no, thats downplaying what has been reported nation wide wherever there is a data center. Brownout, blackouts. Increased temps of surrounding land by a significant amount, water pressure going to almost zero, the aquafier getting fouled up. It will create a few jobs construction wise, temporarily then everyone nearby gets to deal with the outcome. It won't bother those who are making money off of it, but sure as hell affect everyone's quality of life out here. All for what? AI slop?
I absolutely oppose a data center in Missoula County. Montana should not be participating in or entertaining the idea of building these centers. A super bad idea for water use and natural resources.
Bonner is a growing part of Missoula county, I know the county commissioners have a desire to create a vibrant community in this area. A data center is not the way forward for that goal.The impacts of allowing this data center will be far reaching and possibly irreversible once it's allowed to set its teeth in. If we want to continue to improve this area we need to be really careful what we allow in. As a resident of West riverside, seeing a data center approved for the mill would feel like a huge misstep. I realize the need for industry and jobs but a data center will not bring enough jobs to justify its existence. The bottom line is a Data center will make everything worse not better.
MONTANA DOES NOT WANT NOR SUPPORT A DATA CENTER ! OUR STATE IS PRISTINE AS IS WITH ADEQUATE WATER ! NO TO DATA CENTER, HIGHER ENERGY RATES AND DESTRUCTION OF OUR BEAUTIFUL STATE ONLY FOR THE BENEFIT OF OLIGARCHY/WEALTHY INDIVIDUALS WHO COULD CARE LESS ABOUT OUR CLEAN WATER AND MAINTAINING ENERGY BILLS WITHOUT BIG BUSINESS INTERFERENCE !
I strongly oppose the proposed Bonner data center and respectfully urge the Missoula County Board of County Commissioners to reject this Special Exception request.
At its core, this project does not fit the Bonner community, its surrounding environment, or the infrastructure residents rely on. Rebranding a large-scale industrial operation simply because it sits within an existing structure does not make it compatible.
**Groundwater** is the most serious concern—and, on its own, should be enough to disqualify the proposal. Data centers consume vast quantities of water for cooling, often reaching millions of gallons annually. The Clark Fork and Blackfoot River corridors, along with the aquifers that sustain them, are not limitless industrial supplies. They are essential for agriculture, wildlife habitat, and local drinking water. Once groundwater is depleted or contaminated, it cannot be easily restored. The county has a responsibility to safeguard this resource for both current residents and future generations, rather than risk it for a speculative industrial use.
**Infrastructure limitations** are another major issue. Roads, utilities, and public services in the Bonner area were not built to handle the demands of a heavy industrial data center. Construction alone—followed by ongoing maintenance traffic, electrical upgrades, and logistical support—would place significant strain on the community. These impacts would fall on nearby residents who neither benefit proportionally nor have meaningful input in bearing those costs.
**The Special Exception standard exists for a reason.** This application requires one precisely because the site is near residential areas. That is not a minor technicality—it is the central concern. The process is intended to protect communities like Bonner from incompatible development. The burden rests with the applicant to clearly prove that the project will not harm neighbors, strain infrastructure, or threaten water resources. That standard has not been met.
This position is not anti-development. The Bonner Mill site presents a real opportunity for thoughtful redevelopment. But any future use should align with the scale of the site, the capacity of local infrastructure, and the needs of the community—not impose a large industrial operation with significant external costs and limited local return.
For these reasons, I ask that you deny this application.
My name is Justin Enger. My wife and I live at 9309 Highway 200. We strongly oppose the proposed data center. We live right across the street from the planer where the new data center will go into. What will happen to our home and our health after this is put in? What will happen to the homes and health of the community? What will happen to the groundwater and surface water in the blackfoot watershed? What will happen to our electric bills? All this for maybe 10 permanent jobs?
Please consider the impact for the minimal gain of jobs and the rippling side effects this will have for the community and environment. Consider the kids who live in Bonner and attend the K through 8 school. What will happen to them as highly susceptible individuals?
Also consider the lies that were spilled at the public meeting. Why did they lie about the megawatts that would be used? What else are they lying about?
I am all for advancement in our community but 10 jobs is not that plus all the other negatives that come with a data center.
Please listen to the community in Bonner and the greater Missoula County Community. We do not want a data center. Please oppose it.
Sincerely,
Justin Enger
Bonner resident
We all need to come together to stop this proposed data center. It has no place in such a beautiful area, near the Kettlehouse Amphitheater. It would ruin this concert setting with the constant noise, let alone the peoples that live there peaceful enjoyment. The power draws are too massive and the precious water use is too much. We must stop this!!!
I strongly believe a data center in Bonner or anywhere in Missoula County is a huge mistake. It's energy needs equals that of 100,000 homes; the current size of Missoula. The constant noise pollution to an area that includes nearby homes, an elementary school and a world-class music venue is unacceptable. Lastly, the data center will be next to most iconic river in the west. Why do we also trash the things we love-beauty, nature, communities and silence.
I am absolutely opposed to approving ANY KIND of noisy, energy-consuming data center in my backyard...right on the Blackfoot River--the river that runs through it, of all places!! Stop this nonsense.
