Overview: Why an SEIS is being prepared
On July 29, 2026, NewRange notified the DNR of proposed changes to their NorthMet Project. Under state law, the DNR, as the responsible governmental unit (RGU), is required to prepare an SEIS when a project’s proposed changes to the project are substantial and affect the potential for significant environmental impacts of the project or if there is new information that could significantly affect those potential impacts. After reviewing the proposed changes to the NorthMet Project, the DNR determined on [DATE] that an SEIS is required.
The DNR will prepare an independent, state-only SEIS to evaluate the proposed project. The agency understands that the U.S. Army Corps of Engineers (USACE) will prepare a federal SEIS under the National Environmental Policy Act, which serves a similar purpose to the state’s environmental review. The DNR will work cooperatively with USACE to reduce duplication and coordinate its review of the project on matters such as data submittals, analytical approaches and public participation. The DNR will also seek to coordinate with USACE to support a more efficient and aligned engagement and consultation with Tribal governments.
Background: 2015 final EIS history
Between 2005 and 2015, the NorthMet Project underwent an extensive environmental review process. In accordance with state and federal laws, a joint state/federal EIS was prepared under the leadership of the DNR, USACE and the U.S. Forest Service (USFS). This process resulted in the NorthMet Mining and Land Exchange Final Environmental Impact Statement. The Final state EIS was deemed adequate by the DNR in March 2016, marking the end of the state's environmental review process.

Next steps: The SEIS process
The SEIS builds on the original 2015 Final EIS by analyzing new information and project changes. It does not replace or reopen the 2015 Final EIS. The SEIS will describe the revised project, evaluate potential environmental impacts and consider alternatives and mitigation measures that could reduce those impacts. This information will be used by regulatory agencies when making future permitting and approval decisions. The SEIS itself is not a decision to approve or deny the proposed project. Environmental review is separate from permitting decisions.
The SEIS process includes three phases: 1) Develop and distribute the Preparation Notice; 2) Develop and distribute the draft and final SEIS; and 3) Review and determine the adequacy of the SEIS.
The DNR is currently developing the SEIS preparation notice. This document will identify what has changed since the 2015 Final EIS, including new information or circumstances that may affect environmental or socioeconomic impacts. It will also outline issues to be analyzed, project alternatives to be examined, studies to be undertaken and provide a schedule for preparing the SEIS. Other agencies and Tribal Governments may provide input during this phase.
