The Minnesota Department of Natural Resources (DNR) issues leases to private companies and local governments to mine construction aggregates (sand and gravel, crushed stone) on school trust lands and other state-administered lands. This type of state lease is called an earth materials lease and is required prior to any aggregate mining on state-owned lands administered by the DNR.
A state earth materials lease requires a minimum annual production fee along with a payment for all materials removed. A state lease also includes requirements for environmental controls and reclamation of the site. Before a lease is issued, the lessee must provide a certificate of insurance by an insurance carrier licensed to do business in Minnesota at the amount specified in state law.
Earth materials leases may be issued upon application or are awarded as part of a public bid sale. At a public bid sale, the highest qualified bidder is awarded the lease. Under certain circumstances, "over-the-counter" permits may be issued for an additional fee.
