Minnesota Governor Tim Walz announced on Tuesday that the state would halt the review and processing of permits for proposed mining ventures in the Boundary Waters Canoe Area Wilderness, following the federal ban lift by the U.S. Congress and President Donald Trump’s administration four months earlier.
The Boundary Waters Canoe Area Wilderness spans approximately 240 kilometers along Minnesota’s border with Canada within the Superior National Forest, located just south of Quetico Provincial Park in Ontario. This pristine area attracts thousands of outdoor enthusiasts each year, including canoeists, kayakers, and campers.
Governor Walz, a Democrat, emphasized the importance of preserving the wilderness in its natural state, stating, “It’s our responsibility as Minnesotans to ensure the sanctity of this place remains untouched and unspoiled.”
However, Walz’s executive order may have a limited lifespan as per state regulations, expiring in April, 90 days after the governor’s term ends, allowing the possibility for the next governor to reverse the decision.
Although there are no immediate mining projects ready to commence, Twin Metals Minnesota LLC, a subsidiary of Antofagasta Minerals based in Chile, has been actively pursuing copper, nickel, and other mineral extractions in the national forest since 2019. The company asserts that it can conduct mining operations without leaving waste rock above ground to mitigate environmental impacts like acid drainage.
Environmental concerns have been raised due to the proximity of the proposed mining site to the Boundary Waters Canoe Area, with fears that excavation activities could lead to pollution in the area.
In a controversial move in April, President Trump signed a resolution approved by Congress, lifting the federal mining ban in the forest, citing job creation and industry growth benefits.
Governor Walz’s order also prohibits Minnesota regulators from participating in federal environmental reviews of nonferrous mining in the Rainy River watershed, which is connected to the Boundary Waters. Additionally, the state will refrain from conducting environmental assessments or permit processing for mining proposals during ongoing legal disputes over state mining regulations.
Furthermore, Walz has directed the Minnesota Department of Natural Resources to develop legislation banning nonferrous mining activities in the Rainy River watershed.
Reacting to the governor’s decision, U.S. Rep. Pete Stauber, a Republican, criticized Walz, accusing him of launching an assault on northern Minnesota’s livelihood and traditions. Stauber condemned the overturning of years of rigorous review, environmental assessments, and significant private investments by the outgoing governor.
The advocacy group Save the Boundary Waters, represented by chairperson Becky Rom, commended Governor Walz for his stance, emphasizing the incompatibility of copper mining with the Boundary Waters’ preservation. Rom highlighted the governor’s action as a crucial step in safeguarding clean water sources, the wilderness integrity, and the outdoor recreation economy that Minnesotans value.
Legal expert James Coleman from the University of Minnesota Law School noted that Walz’s order injects uncertainty into potential mining projects, emphasizing the prolonged timeline and the influence of changing political landscapes at the state and federal levels on project outcomes.
