financial assurance; reclamation; escrow; trusts
HB2278 revises Arizona’s mining reclamation financial assurance laws for exploration operations, mining units, and aggregate mining units. The bill adds a third-party escrow or trust account as an expressly allowed financial assurance mechanism, alongside existing tools such as surety bonds, letters of credit, insurance policies, cash deposits, certificates of deposit, and bonding pools. It also updates the statutes to clarify that interest and earnings on money held in a third-party escrow or trust account belong to the owner or operator, after any administrative fees and costs charged by the account.
The bill further requires the state mine inspector to release the proportional share of interest earned when financial assurance is partially released or substituted, and to release remaining funds after reclamation work is completed, while retaining 10% for care, monitoring, and possible reseeding for revegetated areas. The retained amount must be released after no more than three growing seasons, subject to existing statutory conditions. In effect, the bill modernizes how reclamation funds may be held and how earnings on those funds are treated, while preserving the inspector’s authority to ensure reclamation obligations are satisfied.
HB2278 amends A.R.S. sections 27-991, 27-996, 27-1291, and 27-1296, which govern financial assurance for reclamation of mining and aggregate operations. The practical legal change is the addition of third-party escrow or trust accounts as an authorized financial assurance option and the explicit assignment of interest earnings on those accounts to the operator, net of fees. It also requires proportional release of earned interest when assurance is partially released, affecting how operators, escrow trustees, and the state mine inspector administer reclamation security and fund releases.
The bill appears to have generally favorable support, as reflected by committee approvals and passage in both chambers, though not unanimously. It cleared the House Natural Resources, Energy & Water Committee, House Rules, House third reading, Senate Natural Resources, Senate Rules, Committee of the Whole, and Senate third reading, and was ultimately signed by the governor. The vote margins suggest the measure was broadly acceptable but not without some opposition, especially in floor votes.
The main point of contention appears to be whether allowing third-party escrow or trust accounts, and giving the associated interest earnings to operators, appropriately balances industry flexibility with reclamation protection. Supporters likely viewed the bill as a modernization of financial assurance options and a clarification of ownership of accrued interest, while opponents may have been concerned about reduced public control over reclamation funds or the adequacy of safeguards when funds are held outside traditional state-administered mechanisms. The recorded no votes in committee and on the floor indicate some concern, but the bill still advanced with majority support.
