Revise state finance laws related to ARPA interest and the coal trust fund

This bill requires Montana's state treasurer to transfer all interest earnings from American Rescue Plan Act (ARPA) funds into the coal severance tax permanent fund within 10 days of the bill's effective date. It appropriates $100 from the general fund to the Department of Revenue for implementing this transfer. The bill directly affects state financial management by redirecting ARPA-related interest earnings to a specific trust fund established under Montana's constitution, without changing the original ARPA funds' purpose. The transfer is effective immediately upon passage, with no new policy creation - only a procedural adjustment of existing funds.
