MINNEAPOLIS (AP) — The Minnesota Supreme Court will hear arguments on an attempt by environmental groups to cancel a key permit for a long-stalled copper-nickel mine.
Opponents of PolyMet Mining Corp.′s project say state regulators should have included “end-of-pipe” limits on discharges of mercury, sulfates and other pollutants in the water quality permit.
