Record of Decision on Environmental Assessment Worksheet (EAW)
The Minnesota Department of Natural Resources (DNR), as the Responsible Governmental Unit for environmental review of the Mile Post 7 West Ridge Railroad Relocation, Dam Extensions, and Stream Mitigation Project located in Lake County, Minnesota, has issued a Record of Decision regarding the Need for an Environmental Impact Statement for the project.
The DNR has concluded that an Environmental Impact Statement (EIS) is not required because the project does not have the potential for significant environmental effects. The justification for this determination is contained in the Record of Decision. The Record of Decision also contains the Department’s responses to all written comments received on the Environmental Assessment Worksheet during the 30-day public review and comment period.
Issuing this Record of Decision concludes the state environmental review process for this project according to the State Environmental Review rules, Minnesota Rules part 4410.1000 to 4410.1700. This project can proceed to permitting and approvals.

The proposed project
Northshore Mining Company has proposed to conduct certain activities and stream mitigation at its Mile Post 7 Tailings Basin. The proposed Tailings Basin Features cover approximately 339.1 acres and consists of relocating the existing railroad embankment, extending Dams 1 and 2, constructing a Dam 1 rail switchback, and excavating clay from a borrow pit for dam construction. The project also includes approximately 20,665 linear feet of stream mitigation at six separate sites.
