Opponents say the latest legal setback for the proposed PolyMet copper-nickel mine — the Court of Appeals ordering more review of the air permit — shows it’s a failed proposal.  Aaron Klemz with Minnesota Center for Environmental Advocacy:

“For all four of these permits, those are permits they need to operate and construct the mine.  All of them have been either reversed, remanded or suspended.”

Polymet in a statement says it’s disappointed in the court’s decision but believes the Pollution Control Agency appropriately accounted for potential effects of the project.  The company says “the facts and science that prove the project can meet air quality standards are not in doubt.”
