Permanent mining ban proposed for 225,504 acres near Boundary Waters

What does this do?

HR 588 would permanently ban copper, nickel, and other sulfide-ore metal mining on about 225,504 acres of federal land in northeastern Minnesota. The land drains into the Boundary Waters Canoe Area Wilderness and Voyageurs National Park. Sand, gravel, granite, iron ore, and taconite could still be removed if the Forest Service determines it would not harm water quality, air quality, or the forest.

Who does it affect?

Mining companies holding or seeking mineral rights in the Superior National Forest are directly affected, as are three Ojibwe tribal nations with treaty hunting and fishing rights in the area. Outdoor recreation businesses, tourism operators, roughly 150,000 annual visitors to the Boundary Waters, and local workers in northeastern Minnesota are also affected.

Why does it matter?

Sulfide minerals exposed to air and water can produce sulfuric acid and release harmful metals such as lead, copper, and cadmium into waterways. A study cited in the bill found that all 14 U.S. copper sulfide mines examined had spills or leaks, and the Boundary Waters and Voyageurs National Park are classified as top-quality water resources under federal and state law.
