The Minnesota Supreme Court will decide whether state regulators erred in issuing permits for PolyMet Mining Corp.’s copper-nickel mine without a special hearing, and could impose further review of the $1 billion project.
The state’s highest court became involved Tuesday in the landmark mine project near Hoyt Lakes — a new type of mine for the state — after an appellate court struck down three permits and sent them back to the state Department of Natural Resources (DNR) for a contested case hearing.
The lower court reversed PolyMet’s permit to mine and two dam safety permits in January, partly on the grounds that the DNR did not hold the contested-case hearing to vet significant objections from environmentalists and the Fond du Lac Band of Lake Superior Chippewa, who live downstream from the planned mine.
