A bill that pushes forward a proposed land exchange between PolyMet and the U.S. Forest Service has been passed by the House Tuesday.
It's called the Superior National Forest Land Exchange Act of 2017, introduced by Democratic U.S. Representative Rick Nolan.
Proponents say it's a critical piece to opening up the copper, nickel, and other precious minerals under Iron Range Land known as the Duluth Complex.
Essentially, the proposal would transfer roughly 6,700 acres of private land into public use. In return, PolyMet will receive roughly 6,600 acres of land to be used for mining.
Governor Mark Dayton has recently expressed support for the project. Opponents say the project threatens the health of northern Minnesota waterways, and wouldn't come with the economic boost supporters claim.
The bill now goes to the Senate. If passed, it will head to the President's desk for a signature.
