PolyMet Permit to Mine Struck Down

Today, the Minnesota Court of Appeals overturned the Minnesota Department of Natural Resources (DNR) permits for the PolyMet mine. The PolyMet mine cannot go forward unless the project receives new DNR permits after a contested case hearing. 

The Court flagged tailings dam safety, wet closure of the tailings basin, financial assurance, and putting Glencore on the permit as issues where WaterLegacy and our allies had proved the need for a contested case.

Minnesota Court Rejects 2 Major Permits for PolyMet MineThe New York Times, January 13, 2020

Paula Maccabee, an attorney for WaterLegacy, one of the groups that challenged the permits, called the decision “an absolutely enormous victory.” She said in an interview that the hearing will mean a trial-like proceeding “in an open and transparent process for everyone to see. That mean’s PolyMet’s toxic environmental threats will finally get the scrutiny they deserve.”
