Public Waters Work Permit

The DNR Public Waters Work Permit Program applies to those lakes, wetlands, and streams identified on DNR Public Water Inventory maps. Proposed projects affecting the course, current, or cross-section of these water bodies may require a Public Waters Work Permit from the DNR and permits from other agencies.

Under Minnesota Statute 103G.245, Subdivision 1 (except as provided in Subdivisions 2, 11, and 12), the state, a political subdivision of the state, a public or private corporation, or a person, must have a DNR Public Waters Work Permit to:

  1. construct, reconstruct, remove, abandon, transfer ownership of, or make any change in a reservoir, dam, or waterway obstruction on public waters; or
  2. change or diminish the course, current, or cross section of public waters, entirely or partially within the state, by any means, including filling, excavating, or placing of materials in or on the beds of public waters.

PolyMet has submitted its Public Waters Work Permit application for the proposed NorthMet project. The DNR will now start the application review process. Next, we will initiate concurrent review by technical experts from units of government that have jurisdiction in this matter, as applicable in MN Rule.
