2021 Public Hearings on Cryptocurrency Mining Zoning Regulations 

In April 2019, Missoula County adopted interim zoning regulations for cryptocurrency mining operations; those regulations were renewed in April 2020 and are set to expire in April 2021. Missoula County proposes to adopt those countywide regulations on a permanent basis to apply to all cryptocurrency mining operations in the unincorporated areas of Missoula County and will conduct public hearings according to the schedule below.

The proposed zoning permits cryptocurrency mining operations as conditional or special uses in areas zoned C-I1 (Light Industry) and C-I2 (Heavy Industry) and requires them to meet criteria to mitigate adverse impacts, including climate change impacts resulting from high energy consumption, noise pollution, and electronic waste disposal.

The proposed permanent zoning regulations are available here.

The staff report to Planning Board is available here.
