The data center fight in Butte-Silver Bow, Montana
As of September 27, 2026, Butte-Silver Bow, Montana has a data center moratorium under consideration (action taken Sep 2, 2026).
Status is derived, not stored — a pause with a documented end date flips to Expired on its own — and the source is right next to the claim.
Status today
Commission voted 11-0 on Sep 2 to direct county attorney to prepare interim zoning ordinance for temporary moratorium. Requires three additional votes plus 30-day wait before implementation. Would be 6 months with option to extend to 1 year, up to 2.5 years total. Separately, a ballot initiative by 406 People First to require 2/3 voter approval for DCs was blocked — judge ruled Aug 28 that signature deadline had passed; group has appealed to MT Supreme Court.

An expiry date is the earliest a pause could have ended — extensions are common, so confirm with the clerk before citing it.

As of August 2026 · changes weekly — re-check before citing
Illustrative rather than exhaustive — dozens of localities churn weekly, and this tracks the ones we have read a source for. **Each row carries its own provenance.** Rows showing a verification date link to the ordinance, the enacting body's own page, or a datable report of the vote, and were read on that date. Rows marked *unverified* came from bulk compilation and have not been checked against a primary source — the locality, the year, and the status may all be off. Verify one of those with the town clerk before citing it as precedent. **Expiry is derived, not asserted.** A row with a documented end date flips to *Expired* on its own once that date passes. A time-limited moratorium whose start date was never documented keeps showing as enacted — that is a known gap, not a claim that it is still in force. Moratoriums are also routinely extended, so an expiry date is the earliest it could have ended, not proof that it did.
