Boundary Water Canoe Area Wilderness mining restrictions modified.

HF 309 amends Minnesota Statutes §84.523 to tighten mining restrictions in the Boundary Waters Canoe Area Wilderness (BWCA) and Rainy River headwaters. The bill requires the commissioner of natural resources to determine that proposed mining (for taconite, sand, gravel, or granite) in the Rainy River headwaters would not harm the BWCA before any permits are issued. This modifies existing law by adding this specific assessment step, directly affecting mining operations seeking approval in these areas. The change maintains the general prohibition on mining without legislative approval but adds a new administrative requirement for the commissioner to evaluate environmental impacts. The bill focuses on protecting the BWCA's wilderness character through stricter permitting conditions.
