Three environmental advocacy a groups are planning a lawsuit over pollution violations from the tailings basins of the former LTV Steel plant near Hoyt Lakes which PolyMet Mining intends to use for its planned copper-nickel mining operation.
The Minnesota Pollution Control Agency passed new regulations aimed at reducing haze over northern Minnesota, including Voyageurs National Park and the Boundary Waters Canoe Area Wilderness. The MPCA board voted 7-1 in favor of the new rules, despite calls for tighter restrictions.
Last week several environmental groups asked federal agencies and the state of Minnesota to take a more active role in preventing air pollution that contributes to haze over Voyageurs and Isle Royale National Parks and the Boundary Waters Canoe Area Wilderness.
A regional haze plan developed by the Minnesota Pollution Control agency seeks to address visibility impairment and haze in the Boundary Waters Canoe Area Wilderness and Voyageurs National Park. The plan is open for public comment until September 3.
