Comment Now to Oppose PolyMet Permits for Long Term Pollution

In January 2018, the Minnesota DNR released a draft permit to mine for PolyMet’s proposed copper-sulfide mine. 

Toxic seepage from PolyMet’s copper-nickel sulfide mine pits and wastes containing sulfate and toxic heavy metals would last for centuries, if not forever.  Mine closure and centuries of water treatment would cost more than $1 billon, but PolyMet could get a permit to mine by guaranteeing less than 10% of that amount up front, with almost no insurance for spills or dam collapse.
