Committee introduces proposal requiring decommissioning deposits for wind developments

Representative Kevin Andrus introduced RS 32183 to require owners of wind turbine sites to obtain an outside estimate of the reasonably anticipated cost to remove turbines and restore the site, and to remit that amount as a cash decommissioning deposit to the state treasurer before fabrication begins. “...they have to put that amount of money in a fund at the treasurer's office,” Andrus said.

The bill requires an owner, at the owner’s expense, to cause an inspection and cost estimate for full decommissioning; the owner then must either perform the cleanup when the site is decommissioned or the state may use the deposited funds to complete restoration. Committee members asked whether the deposit should be held as cash with the treasurer or posted as a bond, and raised concerns about inflation eroding long-term adequacy of deposits. Representative Barbieri suggested additional guarantees from company principals or periodic adjustments for inflation might be needed; Representative Keeley noted cash deposits could earn returns that partially offset inflation.

Committee members also sought clarification about which state agency would determine the deposit amount. The bill text and discussion referenced the Idaho Department of Lands in calculations and inspections; the sponsor said the owner must cause the estimate but the department participates in the determination. The committee approved a motion to introduce RS 32183; the motion carried by voice vote.
