Minnesota’s highest tribunal ruled in favour of PolyMet Mining Corp over the air emission permit of USD1.0 billion copper-nickel-platinum mine.
- The court reversed the rejection of the air emissions permit by the appeals court, stating that the federal Clean Air Act doesn't require the Minnesota Pollution Control Agency (MPCA) to investigate allegations by Native American tribe, "sham permitting", and environmental groups.
- NorthMet is fully owned by PolyMet and is located in one of the world's underdeveloped mining regions north of Minneapolis near the Canadian border.
- The court sent the case for further proceedings to the Court of Appeals. However, the decision was a partial defeat for opponents as they got another chance to press the company for not complying with all terms of the permit.
- PolyMet is backed by Swiss commodities heavyweight Glencore, who is positive for the final decision.
- The company has many hurdles before the start of mine, including the court's decision to cancel the mine permit, and dam safety permits are still pending.
