Project overview

A property owner in Bonner has submitted a preliminary application to Missoula County Planning, Development and Sustainability for a proposal to lease the planer building at the Old Bonner Mill to a company planning to establish a data center. The site, generally located at 9314 Bonner Mill Road in the Bonner Mill Industrial Park, is zoned Industrial Center, Heavy. A data center would be an allowed use on the property.

Missoula County has additional zoning regulations that apply to data centers and cryptocurrency operations throughout the county. These include:

  • All power for the operation must come from a new renewable energy source (meaning it has not been on the market yet)

  • The operation must recycle all electronic waste

  • Because it is located within 500 feet of a residential area, the proposal must go through a special exception review to ensure impacts to nearby properties are addressed, including traffic, noise, lighting, landscaping, and screening and buffering

Project process

The project would be subject to approval by the Missoula County Consolidated Land Use Board, not the county commissioners. While the land use board at times only has authority to make recommendations to the commissioners, the board does have final decision-making authority in some cases, including zoning variances, zoning special exceptions and administrative action appeals.

The land use board has authority to approve or deny a proposal to locate a data center within 500 feet of residential use, but the applicant must still secure a zoning compliance permit from the County ensuring they meet the requirements to recycle e-waste and supply the operation with new renewable energy, as required by the cryptocurrency zoning. The board may consider this project in early May at the earliest. The project would also need to get other County permits to operate, such as building and other trade permits. These are subject to administrative review and do not involve a public process.

What is a special exception?

A special exception is defined as an allowed use that meets the intent of the zoning in an area, but which, because of location, scale, required infrastructure or other potential impacts, requires a special degree of consideration and control to ensure it is consistent and compatible with the overall community character.

State law and local regulations require the Board of Adjustment to be the reviewing and approving authority for special exception requests. (The Consolidated Land Board serves as the Board of Adjustment for Missoula County.)

What’s next?

The project is still in its initial stages, and Missoula County has not received a formal application yet, which is typically the point when public engagement starts. Due to heightened public interest though, residents are invited to ask questions and submit comments using the tools below.

County staff attended, but did not organize, a community meeting Friends of 2 Rivers hosted on March 20 in Bonner. If a formal application is received, the public will have a chance to weigh in on this project at a public meeting of the land board. Follow this project page to be notified when a meeting is set.

I feel for the Mill owner, and I understand that it has been hard to find a tenant for his largest building. However, I do not want a data center in our community. After attending the first public meeting and listening to the staff of Krambu speak, I do not feel any sort of confidence that they are being upfront and have our community’s best interest in mind. Most of their answers were vague, at best, and there are still a lot of unknowns around this particular type of data center because it will be one of the first of its kind. This kind of energy sucking and truly unnecessary kind of business does not belong near a residential areas and water sheds. So much more would need to be disclosed for me to be on board with this project, and I do not have confidence that this business has any intention of that.

As a Missoula resident, I do not want this data center. A data center in this location, or any location, puts natural resources, and in turn, local residents, at risk. Montana does not need data centers. Natural resources, water especially, are at a higher risk now more than ever before. Preventative measures are better than damage control. Listen to the people - we DO NOT want this.

There's not strong enough language in the world for how vehemently I am opposed to this project. Montanans don't need— and certainly do NOT want— this huge disaster for our Blackfoot river. We don't want this noise-polluting, energy-sucking monstrosity that will inevitably cause our already sky-high utility rates to go up.

There are other comments highlighting the ethical and social catastrophes that AI cause (see the MIT study on cognitive decline in AI users that at least one other commenter cited). That's reason enough to oppose this project that will create... just how many jobs for the community? Five? Six?

The CEO of the California-headquarted company Krambu called this an "AI factory." Call it what it really is: an urban heat island factory, a noise pollution factory, an online-disinformation factory, a cost-of-living-increasing factory... the list goes on and on.

As concerned neighbors, we are demanding that this project not be approved. There is so very little to gain, and so much to lose. Please, do the right thing for our community and do not approve this awful, awful project.

We don't want or need that here! It will affect and pollute our beautiful river and lands. we will continue to fight it

Iv7thgen 17 days ago

We don't need an AI data center in Bonner. As a Missoula resident, I am extremely wary of how plans can change from original promises, in terms of energy used, pollution expected and general impact contained. Things like this always balloon more than expected. Allowing this project opens the door to future projects getting pushed through. Once built, this will never go away. It needs to be extremely clear who is benefiting and why. If it is not clear, there is absolutely reason to be concerned.

Andrew B 17 days ago

We should absolutely not approve this. This story has already played out across the country, with the same result every time. This will only result in higher energy prices, environmental degradation, and no notable boost to the local economy. We should take a lesson from the numerous other communities this has happened to, and not allow this project to proceed, especially on the banks on the Blackfoot river, an invaluable treasure to our community. I strongly oppose this plan.

I would like to express dismay that this project is being considered. Several research studies have shown that data centers raise the temperature of the surrounding area (up to 6.2 miles away) by an average of 9.1 degrees. In an era of global warming this seems like a bad idea. Plus I doubt the residents of Bonner will be happy when they experience these higher temperatures.

Also, where is the water used to cool the center going to go? Into the river which does not bode well for fish or fishermen.

I am a constituent living in district 3, Missoula, Montana and am desperately urging you to please do everything in your power to protect our sacred lands, including forests, groundwater, air, and waterways from data centers. Though Montana has signed letters of intent to invite data centers into our state, data centers are a huge draw on public services and increase prices for local governments, residents, and municipalities to support their extreme energy usage. On top of that, these centers do little to nothing to reinvest resources or capital into the local economy. For local residents, including humans and wildlife, they create sound and light pollution, contaminate drinking water, use up valuable freshwater resources for cooling. This effectively destroys fish and wildlife habitat and ecosystems - on which many Montana residents depend for their food and livelihood - as well as reduces availability for agriculture and farming communities who depend on water to grow and raise food. Data centers in Montana would be catastrophic for every single resident. Please do everything you can to require these data centers to generate and use 100% renewable energy at the very least to reduce the financial and energy burden on your constituents.

It should not even be a question that this project needs to be cancelled.
Lack of contribution to the local community aside- this data center is going to result in infrasonic sound waves that are known to cause environmental damage and have effects on HUMAN HEALTH.
Data centers like these, however small, do not belong in populated areas. Full stop.

This project meets Missoula County Zoning guidelines and is an approved use for this property. The property owners need to lease this property. It is a major portion of the property and its occupancy impacts the Mill sites overall viability. Manufacturers are not seeking this Bonner location. We have low wages, high housing costs and huge transportation costs. Ther may not be any other uses for the site except for a data center. The Mill Manager reached out to numerous manufacturers without receiving any interest. This data center will pay an enormous amount of property and business equipment tax. The Bonner School and the Rural Fire Department should be in support of this opportunity. They use minimal water, it's a closed loop system. The noise level is below Missoula County standards. The construction jobs and the data center jobs will be above manufacturing job levels. I support this project.

Please do not go forward with a proposal or contract for this project. Even if a project like this moved forward, it would take years to fully understand the environmental, energy, and community impacts of something like this - and there is already talk of this opening in June. And once its here, its here to stay, as you can read from many other communities that had data centers built in them. They often need more water and energy than initially planned or promised. The company is unclear who their client would be for the data center, and without even knowing a client, how would they be making the promises they are already making on their impact to the community? What's more, with guaranteed impacts on the community and environment, I can't imagine the company has made any guarantees about generating local jobs or giving back to the community. I understand we are in the age of rapidly developing technology with astronomically growing needs, but this site is right next to the Blackfoot, a school, and many houses. I imagine the same promises this company is making now are the same made about the Smurfit-Stone site - and yes, this mill at least provided about 400-500 jobs to the community, but now this sits as an eyesore in our valley, an almost Superfund site, and no end in sight to who will clean it up or when. Bonner would be an awful place for a similar story. https://missoulacountyvoice.com/smurfit-stone-mill-site-cleanup/news_feed/the-smurfit-stone-story

As a Missoula resident I strongly oppose this plan. Building a data center like this has no benefit for our community. This project would pose numerous environmental and health problems for or community and give us nothing. The amount of power required would certainly affect our power supply. The radiation from this large of a center would cause long term health problems for those living nearby. No one benefits from this except the company. Please do not let them take advantage of our community for their own profit.

Chris Woodman 22 days ago

**Absolutely not.** We have nothing to gain from this and so very much to lose. Other comments here say plenty about that, so I’ll leave it there.

One thing though: on NPR today, the person proposing this data center said that its water requirements would not affect the Blackfoot River because water would come from the ground instead. Except…it’s all connected, from ground water to the river to broader impacts (as is everything). For example, see: https://pubs.usgs.gov/publication/fs20133001
Again, all costs, no benefit. NO to this awful idea!

I strongly oppose the data center. Data Centers like these pose environmental hazards and health risks to our community. This project will cause noise pollution to our Bonner and East Missoula community members and potentially cause long term health effects. The location of this near the Blackfoot river is a huge concern for recreation and one of our city's most valuable assets. Don't even get me started on the potential health impacts for Missoulians living downstream from this. Datacenters are power-hungry and will strain our grid, driving up costs for Missoula county residents. The supposed economic benefits this project will bring will be negligible because AI datacenters simply do not create a significant number of new job opportunities, and any benefits are heavily outweighed by the negative impacts. Don't let this AI company profit at our expense!

MIT did a study proving that artificial intelligence lowers cognitive ability and memory in users. AI has no benefit for our society, and Montana doesn't need that. I spent my entire life in Montana and just recently left for college to study environmental science so I can fight issues just like this. This won't give Missoula more money. Though this data center is supposed to use a "new source of renewable energy", we don't know what that is. For jobs? This will MAYBE provide ten jobs. The thing about artificial intelligence is that it can do all of our jobs. Society doesn't need more artificial intelligence! It's been shown useful in radiology, and only radiology. Generative AI, which is what this database would be used for, provides no benefits that outweigh the cost of mining what's necessary for the computers, the energy required to function, and the water it tends to use to cool down the huge computers. This would ruin views and our recreation around the area of Missoula. The datacenter will generate a constant noise, and people won't be able to enjoy the silence that nature provides.
Don't let this happen.

Christiansen, J 24 days ago

As a community member close to Bonner, I strongly oppose this AI data center.

The negative impacts to the community far outweigh a data center's possible positive effects. Noise pollution, light pollution and specific land management planning are just some of Krambu’s are clearly missing considerations in their application.

Please decline this contract moving forward as it will damage the Bonner and surrounding communities.

chloelyons 24 days ago

As a community member who lives within a stones throw of the proposed site, I strongly oppose this AI data center.

Negative impacts to the community remain innumerable and unclear, but obvious in their existence. Krambu’s lack of respect for our land, water, and community was clear at the Friends of 2 Rivers meeting.

The people will continue fighting this, so I hope that Mike Heisey will see what is right and decline to move forward with this contract.

I believe the community could come together and support a creative solution to put something in this space that would be beneficial to us all, if the opportunity was given.

SElizabeth 25 days ago

This Data center is a bad idea. It does not serve the community. It will use gobs of water destroying the environment, gobs of electricity competing with local residents and creating more pollution. It will employ very few people. It will be noisy for local residents. Training 1 AI model creates as much carbon pollution as 5 lifetimes of a car. One of the creators of this says they won’t expand to full capacity? BS! When has an investor or anyone evolved in this kind of venture stopped short of taking it as far as they can. Do not let this happen!

Jerrz 25 days ago

Absolutely not. Do
Not not let this in!! We are losing our water table every year. This will destroy the river and Bonner. This area is too special to sell is u
It and us out!!

Trina 25 days ago

Have we learned nothing from the Berkeley Pit??? Montana is already rife with superfund sites and environmental disasters. And for what? So the rich can get richer while everyone else suffers? This will NOT benefit our community, it will only destroy it. It is unbelievable that this is even being considered!
