Mile Post 7 West Ridge Railroad Relocation, Dam Extension, and Stream Mitigation Project

The proposed project

Northshore Mining Company has proposed to conduct certain activities and stream mitigation at its Mile Post 7 Tailings Basin.

The project also includes approximately 20,665 linear feet of stream mitigation at six separate sites.
