The bill establishes a framework for addressing the decommissioning and cleanup costs associated with coal-fired electric generation facilities in Wyoming. It mandates a study to identify liabilities already incurred for these costs and specifies the responsibility for any additional expenses. The legislation applies to facilities scheduled for retirement, closure, or conversion to alternative fuel sources before January 1, 2034, and requires the public service commission to analyze whether prior rates charged by utilities included recovery for decommissioning and reclamation costs. If it is determined that these costs were not fully covered, recovery will be limited to the portion of power generated for Wyoming ratepayers.

Additionally, the bill appropriates $500,000 from the general fund to the public service commission to conduct the required studies and reports, with deadlines set for updates and final reports by September 2024 and September 2025, respectively. The funds are designated solely for this purpose and cannot be transferred for other uses. The act is effective immediately upon completion of the necessary legislative processes.
