ST. PAUL, Minn. – Federal regulators are recommending that the Army Corps of Engineers decline to reissue a key permit for the proposed PolyMet copper-nickel mine.
The Environmental Protection Agency says the project could raise levels of mercury and other pollutants downstream from the site in northeastern Minnesota. It’s just a recommendation, but it could deal a severe blow to the $1 billion mine if the Army Corps accepts the advice. The EPA announced its position at the start of a three-day hearing in Carlton.
PolyMet says it’s confident the Corps will affirm the permit after it considers all the evidence.
