Revise allocations of coal trust revenue

This bill revises how interest earned from Montana's Coal Severance Tax Permanent Fund is distributed to various state accounts and programs. It directly affects state agencies and public services that receive funding from these coal tax revenues. The key provision extends the termination date for certain highway-related appropriations from June 30, 2027 to June 30, 2029, while maintaining existing allocation percentages for libraries, conservation districts, agriculture, parks, and other state programs. The legislation amends multiple existing statutes to update these distribution rules and ensure continued funding for designated state services.
