Who regulates sand and gravel mining? What permits are required?
In Minnesota, gravel mining operations are generally under the jurisdiction of local government. The township, city and/or county in which the operation is located may have specific regulations for development, operation, or reclamation of a pit. Additionally, a number of state and federal permits may apply that pertain to water quality, water discharge, wetlands, air emissions and mine safety. Environmental review in the form of an Environmental Assessment Worksheet (EAW) is required for operations that will exceed 40 acres to a mean depth of 10 feet. Local government is responsible for the preparation of an EAW. For more information about the permits that may be required for sand and gravel mining, contact your local planning office.
