Support Prove It First

TELL GOVERNOR WALZ TO SUPPORT PROVE IT FIRST

Copper-sulfide mining is the greatest threat to Minnesota’s clean water in decades. The proposed Twin Metals and PolyMet copper-sulfide mines pose an existential threat to the Boundary Waters and Lake Superior. To address this danger, the Prove It First Law would require that before a copper-sulfide mine could be permitted in Minnesota, they must first show independent scientific proof that a copper-sulfide mine has operated elsewhere in the United States for at least ten years without causing pollution AND has been closed for at least ten years without causing pollution.
