The plan for a proposed nickel-sulfide mine that would be built in two watersheds, including the Mississippi, is moving into the next stage of review. 

The public will have its first opportunity to formally weigh in on the Tamarack Mine proposal during an upcoming public comment period through the Department of Natural Resources, set to run July 14 through Sept. 12. 

This public comment period is one of the most important ways for Minnesotans to influence how our state protects clean water, downstream communities and Tribal resources. 

In preparation for this important public comment period, staff from Water Over Nickel and Minnesota Center for Environmental Advocacy as well as FMR's own Colleen O'Connor Toberman are hosting a joint webinar. Together, we'll break down:

  • What's at stake for the Mississippi River and its watershed
  • How this project threatens communities far beyond the mine site 
  • How to participate in the public comment period.

The webinar will be on Tuesday, July 28 from noon-1 p.m. Registration is required. The event will be recorded, and anyone who registers will have access to the recording afterward.
