The federal government says it plans to formally renew the mineral leases for the controversial proposed Twin Metals copper-nickel mine on the doorstep of the Boundary Waters Canoe Area Wilderness.
The U.S. Bureau of Land Management announced Thursday it would grant the 10-year lease extension to Twin Metals Minnesota, a subsidiary of the Chilean mining giant Antofagasta, after a 30-day public review period. The company is pursuing plans for an underground copper-nickel mine near the Kawishiwi River outside Ely, Minn.
It's the latest of several Trump administration reversals this year of the Obama administration's moves to declare a large area of federal land in the Boundary Waters watershed off-limits to mining. Several actions in the waning days of the Obama administration had stripped Twin Metals of its leases in the Superior National Forest, but earlier this year those leases were reinstated and are now up for renewal.
In announcing its plans to renew the leases, the BLM Thursday issued a 34-page environmental assessment of Twin Metals' mining proposal. The agency said the proposal includes updated stipulations to protect natural resources.
The public has until Jan. 22, 2019, to comment on the assessment.
"Twin Metals looks forward to the timely and proper completion of the lease renewal process," the company said in a statement Thursday. "We continue to look forward to the opportunity to present a formal Mine Plan of Operations for review by the federal government."
The company said it plans to submit that plan sometime in 2019. But mining opponents aren't happy with the lease renewal. "The Trump administration is trying to do an end run around the environmental review process and ram through federal approvals while they still can," said Becky Rom, national chair of the Campaign to Save the Boundary Waters.
The mine would be located outside the protected wilderness area, but inside the watershed that flows into it. Environmental groups fear that potential water pollution from Twin Metals and any subsequent mines in the watershed could end up contaminating the Boundary Waters.
The Obama administration proposed a ban on all new mining projects within the watershed for 20 years, and launched an environmental review of that proposal. But the Trump administration ended that study in September, nullifying the proposed ban.
The Twin Metals leases have been the target of an intense back-and-forth in the past several years. Twin Metals hopes to tap a rich deposit of copper, nickel and precious metals hidden deep beneath the lakes and forests of northeastern Minnesota. Its opponents argue such mining would threaten the region's sensitive ecosystem and would imperil the area's burgeoning outdoor recreation-based economy.
The company has explored the region for valuable minerals for nearly a decade, and has projected that its proposed mine could create 650 jobs and operate for at least 30 years. That tantalizing possibility has earned the company the support of many local officials who see the mine as a major potential job creator and economy booster in Minnesota's Iron Range.
The company's two leases date back to 1966, and allow them the right to explore for minerals and propose actual mining projects. The BLM renewed the leases in 1966 and again in 1984. Twin Metals applied for a third renewal in 2012, arguing that under the terms of the lease they enjoyed a nondiscretionary right for a third 10-year term.
But the Obama administration disagreed with that assessment and in late 2016 terminated the leases, citing the "inherent potential risk that development of a regionally untested copper-nickel sulfide ore mine within the same watershed as the BWCAW might cause serious and irreplaceable harm to this unique, iconic, and irreplaceable wilderness area."
At the same time, the administration proposed to ban mining in an area of more than 250,000 acres within that watershed for 20 years.
Over the past year, however, the Trump administration has reversed those moves.
In late 2017, a Department of the Interior attorney issued a new legal opinion, arguing the BLM did not have the discretion to deny the Twin Metals lease renewal. Then, in May 2018, the agency reinstated Twin Metals' mineral leases, paving the way for their proposed renewal today.
Mining opponents have sued the federal government, arguing it broke the law in reinstating the leases. Becky Rom, who works with the Campaign to save the Boundary Waters, argues that, since the federal government revoked the leases under the Obama administration, Twin Metals should have to to apply for new leases, which would require a thorough environmental review.
"The legal process set forth for acquiring new leases is exactly what the Trump administration is trying to avoid," Rom said.
Mining supporters have argued that the right time to evaluate the environmental impacts of copper-nickel mining near the Boundary Waters should wait until Twin Metals proposes a formal mine plan. They say environmental assessment shouldn't happen at the lease renewal stage of the process.
"The renewal of the leases is just one of many important milestones that Twin Metals will work to achieve before entering the robust environmental review process required prior to any mining activity," the business- and labor-backed group Jobs for Minnesotans said in a statement.
But opponents argue that that's too late. They say that scientists should first determine whether the Boundary Waters' watershed is the proper place to conduct this kind of mining, before entertaining specific mining project proposals.
Copper-nickel mining is different from the iron ore mining already happening in Minnesota, because the minerals are bound in sulfide ore. When it's exposed to air and water, it can create sulfuric acid, which can drain from mines and leach heavy metals into waterways.
That's why environmental groups have fought so strenuously against this and other proposed copper-nickel mines. They argue the risk of opening up this new kind of mining near the pristine lakes and rivers of the Boundary Waters isn't worth the economic benefits the mines would bring.
But supporters counter that mining methods have improved dramatically in recent years, and that no mining project will be approved unless it can demonstrate that it will be able to meet all state and federal environmental laws.
Minnesota Gov. Mark Dayton condemned the BLM's decision Thursday, accusing the Trump administration of bending to a foreign corporation at the expense of the state's environment.
"The Boundary Waters Canoe Area is a priceless, irreplaceable environmental asset for our State and Nation that must be protected," Dayton said. "Endangering its pristine waters and natural wonders for the sake of foreign corporate profits is shameful and wrong."
The federal government's announcement about Twin Metals' mineral leases came on the same day that Minnesota's Pollution Control Agency granted crucial air and water permits to a separate copper-nickel mining project, this one proposed by PolyMet for a location deeper into the Iron Range. The announcement marked the final state permits the PolyMet project needs to move forward. If the project breaks ground, as PolyMet says it will sometime in the next year, it will become the first copper-nickel mine in Minnesota.
For four years, Twin Metals' proposal to build an underground copper-nickel mine near Ely, Minn., has wound its way through state and federal agencies and court systems.
The project is not as advanced as the separate PolyMet mine, which would become Minnesota's first copper-nickel mine if it gets final approval of its permits.
December: The Bureau of Land Management renews Twin Metals' leases for a 10-year term, potentially paving the way for mining at the site near Ely, Minn.
September: The U.S. Forest Service canceled a study on the environmental impacts of the mining in the Boundary Waters watershed, putting an end to the government's consideration of a 20-year mining ban in the area proposed by the Obama administration.
June: A group of businesses and an environmental group file the first lawsuit against the government seeking to overturn its reinstatement of Twin Metals' leases. Additional conservation groups subsequently file two more lawsuits.
May: Twin Metals updates its plans for a much smaller copper-nickel mine than it had originally proposed. The updated plans say the mine would employ around 650 people, with a processing plant located near the shore of Birch Lake, about five miles south of the Boundary Waters.
Also in May, the U.S. Dept. of the Interior reinstates Twin Metals' mineral leases, reversing the Obama-era decision to deny their renewal in late 2016.
January: The U.S. Forest Service scales back its study of mining near the Boundary Waters, saying it will conduct a less rigorous Environmental Assessment, rather than an intensive Environmental Impact Statement.
December: A Department of the Interior official reverses the Obama administration's March 2016 legal opinion asserting that the BLM had the right to approve or deny Twin Metals' lease renewal application. The reversal means the BLM and the U.S. Forest Service must reconsider Twin Metals' 2012 lease renewal application. Twin Metals drops its lawsuit against the federal government.
May: Trump administration officials say a study exploring the environmental and economic impacts of mining in the Boundary Waters watershed will proceed.
March: The federal government holds two packed public meetings in Duluth and Ely to gather feedback on its proposal to ban mining exploration and developmenton more than 200,000 acres of federal land.
December: In the waning days of the Obama administration, the Bureau of Land Management and the U.S. Forest Service denied Twin Metals' application to renew its mineral leases. At the same time, the government also initiated a process to potentially ban any new mining developments in the watershed of the Boundary Waters Canoe Area Wilderness for 20 years.
September: Twin Metals sues the federal government, arguing it has the right to an automatic renewal of its leases.
June: The U.S. Forest Service signals it may not allow Twin Metals' leases to be renewed, saying it is "deeply concerned" about mining near the Boundary Waters.
March: Gov. Mark Dayton says he opposes potential copper-nickel mining in the watershed of the Boundary Waters, and denies new lease agreements on state lands. Dayton writes in a letter to Twin Metals that he has an "obligation to ensure [the BWCA area] is not diminished in any way," and that he's "unwilling to take risks with that Minnesota environmental icon."
Also in March, the U.S. Interior Department issues a legal opinion saying Twin Metals does not have the right to an automatic right of renewal of its mineral leases.
April: The Twin Metals mining company details plans for a proposed underground copper-nickel mine near Ely, Minn. The company believes the proposed mine will be "close to the largest underground mine in the U.S.," employing about 1,300 people. The proposal spurs hopes for an economic boom and fears of environmental harm to the nearby Boundary Waters Canoe Area Wilderness.
