Gov. Mark Dayton may direct the state Health Department to conduct a major review of potential health risks from the proposed copper-nickel mine in northeast Minnesota, the first sign that long-standing concerns from top public health officials about drinking water contamination are now gaining traction.
At a news conference Tuesday, Dayton said that such a review won't delay the upcoming permitting phase of the controversial mine PolyMet Mining Corp. is proposing to build at an old taconite site near Hoyt Lakes. But if unavoidable adverse impacts to human health are found, "it certainly could" have a bearing on final approval of the $650 million project, Dayton said.
"Credible medical people" have asked for the health assessment, Dayton said, and he will discuss it later this week with health Commissioner Ed Ehlinger.
Ehlinger, the Minnesota Nurses Association, Minnesota Public Health Association, Minnesota Medical Association, and others in public health have urged the state to include a human health assessment as part of the massive environmental impact analysis of the mine. In his public comment issued a year and a half ago, Ehlinger asked the Minnesota Department of Natural Resources to complete a separate review of health risks, and officials from the two state agencies discussed it earlier this year as well.
But in its final version of the 3,000-page environmental impact statement (EIS) completed Nov. 6, the DNR said no. It said it had reviewed the risks, but found no significant potential health impacts. Doing a broader review would delay completion of the final document, and would not "significantly inform the regulatory permits required for the project," the authors of the EIS said.
A PolyMet spokesman declined to comment, other than to say that the environmental review is completed, and that it concluded there are no public health impacts.
Michael Schommer, a health department spokesman, said that "Commissioner Ehlinger looks forward to discussing the issue with the governor later this week, and to addressing any of his questions about the requests for a health impact assessment."
PolyMet is the first of several mining companies eager to tap into a major copper-nickel deposit that reaches from the Iron Range up into the Boundary Waters Canoe Area Wilderness. Its NorthMet mine would create an estimated 350 jobs and has brought hopes of an economic rebirth to the Range.
