BUTTE, Mont. — The Berkeley Pit has once again put Butte in the national spotlight, this time as part of a much larger debate over where America should build the massive data centers needed to support the country's growing digital infrastructure and artificial intelligence industry.

A Washington Post opinion piece published Thursday pointed directly to Butte's Berkeley Pit while making the case that contaminated industrial properties and Superfund sites could potentially become locations for future data center development.

The idea is relatively simple: Instead of placing massive new data centers on farmland or previously undeveloped property, companies could be encouraged to invest in contaminated industrial areas where redevelopment has historically been difficult and expensive.

In exchange, private investment associated with those projects could potentially help clean up and redevelop contaminated land.

For Butte, however, the discussion comes at an especially interesting time.

Butte Is Already Debating Data Centers

The community is already in the middle of its own heated debate over a proposed large-scale data center.

Washington-based Sabey Data Centers has been evaluating approximately 606 acres at the Montana Connections development west of Butte for a proposed data center campus. According to information released by Butte-Silver Bow's Data Center Impact Committee, the project would initially require about 50 megawatts of electricity and could eventually grow to approximately 200 megawatts.

The proposal has generated questions from residents about electricity rates, water consumption, environmental impacts, tax revenue and how many permanent local jobs a facility of that size would actually create.

The controversy has also resulted in a citizen-led effort seeking to require voter approval before new data centers can be authorized or expanded within Butte-Silver Bow.

That makes the Berkeley Pit's appearance in the national discussion particularly notable.

A New Use for Contaminated Industrial Land?

The Washington Post commentary argues that communities across the country are increasingly pushing back against data centers, while hundreds of heavily contaminated properties remain difficult to redevelop.

The argument is that the two problems could potentially be addressed together by encouraging data center developers to locate projects on Superfund and brownfield properties and participate in their cleanup.

The concept isn't coming entirely out of nowhere.

The Environmental Protection Agency has examined the possibility of using Superfund properties for redevelopment projects including data centers. Sites with existing infrastructure and industrial zoning could potentially be attractive candidates, although each property would have to be evaluated for contamination, cleanup requirements and infrastructure needs.

The Berkeley Pit's Industrial Legacy

The Berkeley Pit itself is part of the Butte Area-Silver Bow Creek Superfund site, a legacy of more than a century of mining and industrial activity in the Butte area.

The massive former open-pit copper mine is approximately 1,600 feet deep and contains hundreds of feet of acidic, mineral-rich water. Contaminated water from the pit and surrounding underground mine workings is continuously monitored and treated.

Cleanup and environmental management throughout the broader Butte Superfund area remain ongoing.

Whether any portion of Butte's Superfund property would actually be appropriate for a data center is an entirely different question. The Washington Post piece does not propose a specific data center at the Berkeley Pit, nor does it connect the existing Sabey proposal directly to the pit.

But the timing puts Butte in an unusual position.

An Old Industrial City Faces a New Industrial Question

A national conversation is developing around the possibility of pairing data center investment with the redevelopment of contaminated industrial land, while Butte residents are simultaneously deciding what role — if any — large data centers should have in the community's future.

Supporters of data center development point to construction spending, property taxes and economic development. Opponents have raised concerns about electricity demand, water use, utility costs and whether the relatively small number of permanent jobs typically associated with highly automated data centers justifies the resources they consume.

Those questions aren't unique to Butte.

Similar fights have emerged elsewhere in Montana and around the country as communities confront an industry expanding rapidly to meet demand for cloud computing and artificial intelligence.

But Butte's history makes the discussion different.

Few American communities understand the long-term consequences of major industrial development better than Butte. Mining created enormous wealth, thousands of jobs and the city itself, but it also left behind environmental problems that generations of residents have had to address.

Now one of the most recognizable symbols of that history — the Berkeley Pit — is being used nationally as an example in a debate about America's next generation of industrial development.

For Butte, that may raise an even bigger question than whether a particular data center should be built.

If the country is going to spend billions of dollars building the infrastructure of the digital age, could some of that investment also be used to repair the environmental legacy of the industrial age?

In Butte, that's no longer just a theoretical question being discussed somewhere else.
