DNR looking into water flow error in Polymet EIS

Duluth, MN (NNCNOW.com) --- The Minnesota Department of Natural Resources is acknowledging an error in the Polymet Environmental Impact Statement currently under review.

According to the DNR, recent data revealed the water flow of the nearby Partridge River is higher than originally reported.

The newest data estimates a base flow rate of 1.3 to 1.8 cubic feet per second, whereas the data used in the EIS estimated flow at 0.5 cubic feet per second.

Experts say the water flow rate estimates how contaminants from the proposed copper nickel mine could spill into the watershed that feeds into Lake Superior.

DNR officials say they are aware of the discrepancy; however hydrologists are not yet sure how much this will affect the EIS.

"Our technical experts have some work to do to determine if we remodel with this parameter," says Steve Colvin of the Minnesota DNR.

This information is coming to light as state officials hold public comment meetings concerning Polymet's proposed copper-nickel mine near Hoyt Lakes.

A third public meeting will be held in St. Paul on January 28th.
