MI SB0591

Establishes a new regulatory program (Part 634) for small native copper mining operations, defined as operations generating 10,000-75,000 tons of waste rock annually or disturbing 1-10 acres annually in calendar year.

Requires small copper mine operators to obtain mining permits from the Department of Environmental Quality, submit $5,000 permit application fees, maintain $50,000 conformance bonds, and pay $5,000 annual operating fees by February 15.

Mandates mining and reclamation plans include baseline water quality sampling (total dissolved solids, copper, nitrate) from up to 5 supply wells and nearest surface water within 1,320 feet of proposed mining area.

Preempts local government regulation of small copper mining activities including construction, operation, closure, and reclamation, though local units may restrict blasting, crushing, and grinding to 6 a.m.-9 p.m. if residential buildings are within 660 feet.

Authorizes department to enter mining areas for inspection, suspend mining activities for emergencies, conduct reclamation if operator fails to comply, and pursue cost recovery through bonds or legal action; establishes small native copper mine surveillance fund for surveillance and enforcement expenses.
