PolyMet Mining Company Applies for Minnesota State Permits


The PolyMet NorthMet sulfide
mine would need more than 20 permits from Minnesota State agencies – primarily from the Minnesota Pollution Control Agency (MPCA) and Minnesota Department of Natural Resources (MDNR)  prior to constructing PolyMet’s proposed open-pit copper-nickel mine, processing plant, tailings waste storage facility and hydrometallurgical waste storage facility.
PolyMet’s permit applications will require the MDNR to review PolyMet’s plans to construct dams to contain waste in permanent rock piles and saturated tailings heaps; appropriate more than 5 billion gallons per year of Minnesota water, and destroy or impair thousands of acres of wetlands. The MDNR will also review PolyMet’s plans to treat wastewater that will be polluted for hundreds of years and to provide financial assurance for costs of treatment, reclamation and potential clean-up of damage and spills.
PolyMet’s permit applications will require the MPCA  and the U.S. Environmental Protection Agency  to review PolyMet’s plans to pollute Minnesota’s wetlands, lakes, rivers, drinking water and to emit air pollutants at both the mine and processing facility. 
The process for permit review and hearings has not yet been determined, although the MDNR has said in their preliminary permitting timeline that there will be a public comment period and public meetings on major MDNR permits. 
Sign up here to be notified when public comment periods begin and public meetings are scheduled regarding PolyMet’s permits.
