This bill, titled the "Boundary Waters Wilderness Protection and Pollution Prevention Act," seeks to permanently safeguard the Boundary Waters Canoe Area Wilderness (BWCAW) and interconnected federal lands and waters, including Voyageurs National Park, within Minnesota's Rainy River Watershed. It achieves this by withdrawing approximately 225,504 acres of federal land and waters from all forms of mineral exploration, development, and leasing. This critical action aims to prevent environmental degradation, particularly from sulfide-ore mining , which poses significant risks to the region's pristine water and air quality. The legislation's findings underscore the BWCAW's ecological importance, including nearly 2,000 lakes and its role within the Rainy River Watershed, which holds 20 percent of the National Forest System's fresh water. These waters are classified as Outstanding Resource Value Waters , and international treaties prohibit their pollution. The bill highlights documented risks of acid mine drainage and spills from sulfide-ore mining, which could severely harm aquatic life and the region's amenity-based tourism industry. The withdrawal specifically prohibits new mining claims and leases on the designated acreage, and any future acquired land within this area will also be protected. However, the Chief of the Forest Service may permit the removal of sand, gravel, granite, iron ore, and taconite if it does not harm water quality, air quality, or forest health. This comprehensive measure ensures the long-term preservation of this nationally significant wilderness area's ecological integrity and wilderness values.
