Keetac Mine Expansion Project


The Minnesota Department of Natural Resources (MNDNR) was the Responsible Governmental Unit (RGU) for conducting an Environmental Impact Statement (EIS) for the proposed U. S. Steel Keetac Mine Expansion Project. The EIS was jointly conducted with the U. S. Army Corps of Engineers (USACE).

U. S. Steel proposes to mine taconite ore from an expanded open pit mine and upgrade and operate a currently idle taconite processing line to increase iron pellet production from 6 million tons a year to 9.6 million tons a year. Keetac is located near the City of Keewatin, MN on the boundary between St. Louis and Itasca counties.

The DNR has determined the final EIS to be adequate pursuant to Minnesota Rules, part 4410.2800, subpart 4.

Draft EIS Documents

Reference EIS Documents

Previously completed EIS documents are incorporated into the Keetac draft EIS and final EIS by reference. The analyses within these documents are relied on in the cumulative effects biomass analysis, Section 5.1. They are used to estimate potential cumulative roundwood harvest impacts associated with the proposed Keetac Mine Expansion Project.

Reference Documents


The MNDNR and USACE scoped the draft EIS from spring of 2008 to November 2008. The MNDNR and the USACE took comments on the draft EIS scope during a 30-day scoping period that concluded on October 8, 2008. A public scoping meeting was held on October 1, 2008 in Nashwauk, Minnesota. The Final Scoping Decision Document operated as the blueprint for EIS preparation.
