Current Action - Halt PolyMet's Dangerous Dam Before It's Too Late
Another mine tailings dam disaster in Brazil has killed 169 people, with 141 still missing. The reaction in Brazil has been swift - the government has now banned all upstream design mine tailings dams and required all existing upstream dams be decommissioned by August 2021.
The mine tailings dam proposed for the PolyMet copper-nickel mine is directly connected to the dam that collapsed in Brazil. It shares the same design now banned in Brazil, used the same consulting engineer, and used the same method to gauge the risk of collapse. We can't afford a disaster here in the headwaters of the St. Louis River, the largest US tributary to Lake Superior.
