Four groups are planning to appeal a recent court ruling that cleared the way for Kennecott Eagle Minerals Co. to go ahead with mining operations in the U.P., the Associated Press reports:
The opposition coalition was filing paperwork Monday asking the Michigan Court of Appeals to overturn a decision last month by Circuit Judge Paula Manderfield. She ruled that the Michigan Department of Environmental Quality acted properly by issuing Kennecott a permit for the project in northwestern Marquette County.
Last month, Michigan Radio's Rebecca Williams explored some of the possible environmental effects the mine could create and spoke with opponents and representatives of the mining company:
Michelle Halley is an attorney for the National Wildlife Federation. It’s one of the groups that challenged (the initial) permit. She says they’re concerned about the type of mining that will happen in the Eagle Mine. It’s sometimes called sulfide mining.
“The rock at Eagle is extremely acid producing, very high in sulfides and so once that rock is exposed to air and water, there’s really no debate it will begin producing acid.”
That acid is sulfuric acid. According to the Environmental Protection Agency... that acid can cause heavy metals to leach from rocks. The resulting fluid can be highly toxic to people and wildlife.
This is called acid mine drainage. On its website, Kennecott Eagle Minerals Company says there is a risk that it can happen. But the company says it’s taking a number of steps to reduce that risk.
Matt Johnson is with Kennecott. He says the company will use a state of the art water treatment plant to purify the mine water using reverse osmosis.
“The entire mine site is designed to control water with water protection in mind. Which is why it’s the company’s commitment not to discharge any water back into the environment until it meets safe drinking quality water (sic) standards.”
And he says the state is also requiring them to do that.
Michigan Radio's Mark Brush followed up with an examination of what the state might gain financially from the project.
