State regulators were largely cleared Thursday of accusations of "procedural irregularities" while issuing a water quality permit for PolyMet Mining Corp. and the copper-nickel mine it wants to build in northeast Minnesota.
In a victory for the mine's supporters and the Minnesota Pollution Control Agency (MPCA), Ramsey County District Court Chief Judge John Guthmann ruled that the MPCA did not deviate from most of its standard practices when it issued the permit.
"The court finds no overarching effort by the MPCA to keep evidence out of the administrative record," Guthmann wrote in a 104-page decision.
The ruling ends an unusual evidentiary hearing that was narrowly focused on the MPCA and how it reviewed and issued the water permit, which is crucial for the controversial mine to go forward.
Mine opponents — a coalition of environmental groups and the Fond du Lac Band of Lake Superior Chippewa — accused the MPCA of destroying notes on important meetings with the U.S. Environmental Protection Agency (EPA), deleting e-mails and suppressing concerns raised about the project by career scientists at the EPA. They also accused the MPCA of destroying important computer records, including wiping the documents from the computer of the former head of the MPCA a month after he left the agency, for example.
In nearly all cases, Guthmann found the MPCA did not deviate from its standards.
"With today's decision, the court renewed its confidence in the MPCA's permitting process for PolyMet," Darin Broton, a spokesman for the MPCA, said in a statement. "While the MPCA always strives to do better, the court overwhelmingly said the agency's permitting procedures were not irregular. The MPCA remains committed to ensuring that its permit processes and decisionmaking are transparent and provide a robust opportunity for public participation."
Guthmann's decision, however, was not a complete exoneration of the MPCA.
