On April 4, 2019, the County Commissioners adopted interim zoning regulations for cryptocurrency mining operations. The regulations take effect immediately for a period of one year and establish conditions that new or expanded cryptocurrency mining operations in the county must meet. The conditions are:

  1. Locate only in light or heavy industrial zoned districts;
  2. Be reviewed as a conditional or special use (which includes a review of noise levels);
  3. Dispose of electronic waste with an e-waste recycling firm licensed by the Montana Department of Environmental Quality; and
  4. Develop or purchase new renewable energy to meet or offset 100% of the electricity consumed at the facility.

In accordance with §76-2-206 MCA, CAPS conducted a study to verify that an emergency exists relative to the impacts of cryptocurrency mining. This study is ongoing and updates will be posted periodically.
