Forest Service finds mining would pose risk to Minnesota watershed

A federal research launched Thursday decided hardrock mining in a Minnesota wilderness space would danger contaminating the realm. 

In its evaluation, the U.S. Forest Service mentioned copper-nickel mining would pose a serious danger to the Boundary Waters Canoe Space Wilderness. Whereas the evaluation is a draft, it proposes a 20-year ban on copper mining on federal lands within the watershed. 

Potential fallout from mining within the space consists of “the creation of completely saved waste supplies” upstream, which might result in the discharge of water with elevated ranges of acidity and steel contamination, the evaluation states. 

“The best potential danger to water high quality of the wilderness space and lands inside the withdrawal areas comes from catastrophic failure of a moist basin tailings storage (impoundment) dam,” the evaluation added. “Moist basin tailings storage poses the chance of dam failure and the potential launch of a giant quantity of contaminated sediment (tailings) and water to a close-by water physique with potential transport of it to downstream water our bodies and receptors.” 

Rep. Betsy McCollum (D-Minn.), whose district consists of the lined space, mentioned the draft illustrates the necessity for a everlasting legislative ban on mining within the space, which she has launched. The manager department doesn’t have the ability to unilaterally ban mining within the space completely. 

“This pristine, valuable wilderness calls for everlasting safety. The EA’s scientific basis leaves little doubt: it is just too dangerous to mine on this location,” McCollum mentioned in a press release. “The proposed 20-year withdrawal is totally justified – and to keep away from the kind of political intervention we beforehand noticed from the Trump administration, my laws should move to completely defend this federal Wilderness and the pursuits of the American folks in perpetuity.” 

The evaluation comes almost six months after the Inside Division introduced the cancellation of two mining leases within the space granted underneath the Trump administration in 2019. The January authorized opinion decided the Trump administration had improperly renewed the leases in 2019 after initially approving them the 12 months earlier than. The Biden administration’s choice prolonged a ban on new mineral leasing inside 225,000 acres for 2 years.
