HB 31 Montana House · 2025 Regular Session

Revise wind and solar facility decommissioning

HB 31 clarifies and revises the bonding requirements for wind and solar generation facility owners in Montana to ensure proper decommissioning. It mandates that facility owners submit a decommissioning plan and provide a bond to the Department of Environmental Quality (DEQ) within specific timeframes after commencing commercial operation. The DEQ determines the bond amount based on factors like site characteristics and salvage value. The bill also outlines various exemptions for facilities already bonded elsewhere or meeting certain size and operation criteria, and establishes penalties for non-compliance.
