The Process

 

EIS Scoping

October 2005

Scoping identified the major environmental issues and alternatives that the EIS would look at. It included a public review and comment period and a public meeting.

 

 

Draft EIS

October 2009

The Draft EIS described potential environmental effects, alternatives to the proposed project, and potential mitigation measures. It included a public review and comment period, and a public meeting to help determine if additional analysis or information was needed.

 

 

Consideration of Comments/Decision to prepare Supplemental Draft EIS

June 2010

This was an optional step in environmental review. The determination to prepare the Supplemental Draft EIS was based on:

  • Significant project changes, including the addition of a land exchange;
  • The decision made by the U.S. Forest Service to develop an EIS for the land exchange;
  • Deficiencies identified during the public review of the Draft EIS.
 

Supplemental Draft EIS

December 2013

The Supplemental Draft EIS included a 90-day public review and comment period and public meetings held in Duluth, St. Paul, and Aurora.
