Minnesota Supreme Court hears dispute over canceled PolyMet mine permits – by Jennifer Bjorhus (Minneapolis Star Tribune – October 13, 2020)


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.

The groups oppose the copper-nickel mine, saying it will pollute nearby waters such as the St. Louis River, with toxic metals and sulfuric acid, often called acid mine drainage, that develops when sulfide-bearing ore is exposed to air and water.
