One of the most vocal opponents of the proposed PolyMet copper-nickel mine in northern Minnesota charged Tuesday that the company may lack the deep pockets necessary to protect taxpayers from bearing environmental clean-up costs years from now when the mine closes.
Paula Maccabee, an attorney for Water Legacy, issued a report saying PolyMet's own financial statements reveal it may not have adequate insurance to protect against risks that are typical in the mining industry. While such disclosures are routine for companies seeking investors, PolyMet's financial partner in the project, the giant global commodities company Glencore, has a troubling environmental track record that makes adequate financial assurances critical, she said.
"There is a lot of work to make sure financial assurance is done, and the time to do that is now," she said.
PolyMet declined to respond to questions Tuesday but said in an e-mail that it would provide all the financial assurances required by state law.
The issue could become critical in coming months as state and federal environmental regulators decide whether to let the $600 million open-pit mining project proceed.
But a top state regulator said Tuesday the question may be put off until much later in the approval process -- despite the urging of both environmental groups and the federal Environmental Protection Agency (EPA) to address it now.
Last year, in a highly critical review of the government's first assessment of the project, the EPA recommended that the second environmental impact statement that is now underway include a thorough review of how much PolyMet needs to provide in financial assurance.
"If post-closure care measures are significantly underfunded, contamination of surface water and ground water may not be controlled," the EPA wrote.
