Revising laws related to state land leases for commercial purposes and the sale of state land.

This bill modifies Montana laws governing the leasing of state land for commercial purposes and the sale of state land, primarily affecting the Department of Natural Resources and potential lessees or buyers. It redefines "commercial purpose" to include various business uses while excluding agriculture, grazing, and energy development, and allows for individual agreements between lessees and the department rather than requiring all leases to go through public auctions. The bill also clarifies that permanent improvements on leased land become state property when the lease ends, and adjusts how land values are determined for sales. These changes aim to streamline commercial land leasing procedures while maintaining oversight through defined appraisal methods and public notice requirements.
