Minnesota DNR - Monthly Update: Twin Metals Minnesota EIS

About this Update

To provide information about the State’s environmental review of Twin Metals Minnesota’s project proposal, the Minnesota DNR will be issuing monthly updates to those who have signed up to receive them on the State web portal for Twin Metals Minnesota project. This message is the monthly update for July 2020.

Each monthly update will provide information on the status of Minnesota’s Environmental Impact Statement (EIS) process as well as identify any new documents that have been posted on the Minnesota DNR’s webpages for the project since the prior monthly update.

Minnesota DNR is the responsible governmental unit (RGU) for the State’s EIS. Please note that the federal government is preparing a separate EIS for the Twin Metals project. Information about the Federal EIS is available here.

State EIS Process Status

Preparation of an EIS for any large and complex project is a multi-year process. Minnesota DNR is currently in the early stages of the scoping phase of the EIS process for the proposed Twin Metals project. The scoping process helps us ensure the future EIS assesses the proposed project’s potentially significant environmental impacts, but also helps define project alternatives, potential mitigations, timelines, and additional data needs.

Twin Metals Minnesota submitted its Project Proposal to Minnesota DNR on December 18, 2019. Since then, we have completed our initial review of the project proposal, determined that it was incomplete, and on June 15, we requested additional information from Twin Metals. On July 24, 2020, Twin Metals submitted its revised Project Proposal to Minnesota DNR along with its responses to our comments. We are now in the process of reviewing this information.

The scoping process is iterative. As is typical for a project of this complexity, we anticipate multiple rounds of Minnesota DNR comments followed by revisions from Twin Metals.
