MCEA is excited to announce our new partnership with Friends of the Boundary Waters Wilderness and Conservation Minnesota on a new online resource regarding sulfide mining in Minnesota: www.MiningTruth.org. Sulfide mining in Minnesota would affect many of our treasured places, including Lake Superior and the Boundary Waters. It’s too important of an issue to be uninformed. Please visit the website to learn more, take the pledge, and tell your friends.

Sulfide mining has never been done in Minnesota. This is not your Grandfather’s taconite mine. It produces toxic waste rock that could irreversibly damage Minnesota’s fragile lakes, rivers and natural resources. It has both economic benefits and drawbacks. Do you believe that sulfide mining has a place in Minnesota?  

Minnesota is a mining state. The iron ore mines of Northern Minnesota built communities and provided good paying jobs during the boom times. Mining has devastated those communities during bad times and damaged the natural environment there with the open pits and disposal of tailings, most famously when Reserve Mining Co. dumped its tailings into Lake Superior.

Minnesota Center for Environmental Advocacy understands mining's place in Minnesota and does not oppose it. However, we do expect all mining, whether for taconite or copper-nickel, to be done through environmentally safe and modern mining techniques that do not leave the state's taxpayers cleaning up a mess.

Overview of Minnesota Mining Issues

Although Minnesota has a long history of iron ore mining, sulfide mining for copper, nickel, and precious metals has never been attempted. Prices for some metals, including copper, reached historic highs in 2011, and some companies have sought to mine Minnesota's low-grade sulfide ores.

The first company to enter the environmental review process is PolyMet, a Canadian company backed by Swiss commodities conglomerate Glencore. The PolyMet NorthMet operation would, if approved, be located in Hoyt Lakes, Minnesota. PolyMet is proposing a 1,728 acre open pit mine with 32,000 tons of ore mined daily. Ninety-nine percent of that ore will be stockpiled as waste rock because the ore is low-grade (meaning very little of it is metal, and large quantities of rock must be blasted and unearthed to recover small quantities of metals).

PolyMet, along with the Minnesota Department of Natural Resources (DNR) and the U.S. Army Corp of Engineers (USACE), have released a draft environmental impact statement (DEIS). Their original DEIS earned an EU-3 (Environmentally Unsatisfactory--Inadequate) rating from EPA--the lowest possible rating. You can read EPA's comments on PolyMet's first draft here, and you can read MCEA's comments on the DEIS here. As a result, PolyMet has had to redo their proposal. In December 2015, PolyMet released a Final Environmental Impact Statement (FEIS). You can find and read MCEA's comments on PolyMet's FEIS here

MCEA has already invested hundreds of hours and thousands of dollars in expertise and legal work on the PolyMet mine, and we will be there if the proposal moves forward to ensure that Minnesota's environmental laws are enforced. Sulfide mining, unfortunately, poses several significant environmental risks. The most significant one is the threat to water quality. When sulfide ores are exposed to air and water, the result is sulfuric acid, which causes the leaching of potentially toxic heavy metals and the release of sulfates that contribute to the methylation of mercury. Methylmercury is the form of mercury that bioaccumulates in fish, and therefore poses a direct threat to human health and the health of wildlife. 

If acid mine drainage and sulfate contamination are not properly controlled at these mines, the damage to fish and wildlife, and ultimately to human health and safety, in the Lake Superior watershed will likely be irreversible. To protect water quality, then, there has to be assurance that the mine operators can and will meet all applicable water quality standards, both during mine operation and indefinitely after mine closure.

Minnesota’s citizens and all those with a stake in the preservation of the Lake Superior watershed do not have that assurance today. The industry's record on water quality is abysmal. Hundreds of hardrock mines in the American West have been abandoned, leaving behind mine pit lakes, waste rock piles, and tailings basins that have contaminated hundreds of miles of rivers and streams. The EPA estimates the total clean-up cost exceeds $50 billion. The hardrock mining industry has been the #1 source of toxic waste in this country ever since the annual Toxics Release Inventory was established.

The environmental risks are not limited to water quality, however. These mines will result in the loss of thousands of acres of protected wetlands, with no adequate wetland restoration and replacement plans yet offered. Many of the contaminants from the ore processing plants will be pumped to tailings basins, with large earthen dams that will require continual monitoring and maintenance to remain stable. These operations require enormous amounts of electrical power to operate, with the only available sources being GHG-emitting coal-fired power plants. And, the mining areas selected are critical habitat for at least one endangered species, the Canada lynx.
