St. Paul, MN (NNCNOW.com) -- PolyMet Mining has announced project improvements in the environmental review of its copper-nickel-precious metals project (the "NorthMet Project") located on the Mesabi Iron Range.

The Minnesota Department of Natural Resources , US Forest Service, and US Army Corps of Engineers are the lead agencies responsible for producing a supplemental draft Environmental Impact Statement, which will describe the project and its potential impacts in detail, providing the foundation for issuance of permits and approvals required to construct and operate the project.

PolyMet says some of the project improvements include:

It has undertaken an extensive review of all aspects of the NorthMet Project which has resulted in numerous improvements that will reduce the Project's environmental impacts.

PolyMet says the reduced environmental impacts include:

Reductions in sulfur dioxide, mercury and greenhouse gas emissions at the plant site, the capture of groundwater and surface seepage with the construction of an in ground containment system to the north and west of the existing tailings basin.

All contact water discharged from the project will be treated through reverse osmosis plants. Officials say contact water discharge will meet applicable state and federal water quality standards, including Minnesota's wild rice standard for sulfate.

These design improvements have been incorporated into the groundwater, surface water and air dispersion models that assess potential environmental impacts of the project.

Jon Cherry, PolyMet's president and CEO stated, "Reductions in the environmental impact of our project are a significant step toward completion of the supplemental draft EIS, which is on track for mid-summer 2013."
