Revert revenue from coal tax to coal trust

This bill modifies how Montana distributes revenue from coal severance taxes by permanently increasing the portion sent to the state's Coal Severance Tax Permanent Fund. It achieves this by redirecting $250,000 annually from the General Fund to the Permanent Fund, which will begin receiving all remaining coal tax revenue starting July 1, 2027. The legislation also maintains existing allocations for libraries, conservation districts, agriculture programs, parks, and other state accounts while adjusting how interest income from the Permanent Fund is distributed to various departments until the transition date.
