ST. PAUL, Minn. (AP) — The Minnesota Pollution Control Agency has signed off the three final state permits sought by the developers of the planned PolyMet copper-nickel mine in northeastern Minnesota.
The agency Thursday announced its approval of the air and water quality permits for the project and a certification of the company’s plan to mitigate the mine’s impact on wetlands. The only remaining federal permit is a wetlands permit from the Army Corps of Engineers.
The Department of Natural Resources last month granted PolyMet the key permit for the project, a permit to mine.
PolyMet would be the state’s first copper-nickel mine. Critics of the open-pit mine near Babbitt cite the risks of acid mine drainage and dam safety concerns. Polymet says it can operate without harming the environment while providing hundreds of jobs.
