  • Grygelko Mitigation Bank Proposal

    Expiration date: 8/1/2025

    This proposal was previously advertised on public notice on December 20, 2023, and the sponsor has made several revisions to the original proposal. The revisions include Hydrocad modeling data, as well as an updated wetland delineation report, credit table, performance standards, and design plans. The sponsor proposes to construct a wetland mitigation bank with credits for bank service area 7, which includes the Twin Cities metro area. The objective of the project is to re-establish fresh wet meadow wetlands with mesic prairie upland buffers by discontinuing agricultural use, breaking and blocking existing drain tile, and planting and establishing native, noninvasive vegetation. The successful achievement of the objectives would result in the rehabilitation of 13.8 acres of fresh wet meadow, the enhancement of 0.50 acre of fresh wet meadow, the establishment of 0.50 acre of fresh wet meadow, and the restoration of 14.8 acres of upland buffer.

In addition, the sponsor is proposing to preserve 7.2 acres of upland prairie and upland forest. The sponsor is proposing to restore these wetland communities by filling ditches to restore wetland hydrology and establishing native vegetation by installing native seed mixes in the wetland and upland communities.

  • HC Wyeville, Grygleski Pit

    Expiration date: 7/15/2025

    The creation of Grygleski Pit is part of the long-term mining plan for HC Wyeville.

The project as proposed will expand the mining operations, allowing HC Wyeville access to additional mineable material, and extend the life of the facility. The Grygleski Pit, as proposed in the preferred alternative, has a life of 3-4 years based on current production rates.

  • 2005-00546-SPK (Mesabi Metalics)

    Expiration date: 7/14/2025

    The U.S. Army Corps of Engineers, St. Paul District (Corps) has received a permit modification request from Mesabi Metallics Company LLC (MMCL) for DA permit MVP-2005-00546-JKA (issued in 2007). The permit and subsequent 2015 modification authorized the discharge of fill material within 765.3 acres of waters of the U.S. (WOTUS) for the purpose of mining taconite ore and producing steel in the Mesabi Iron Range, Itasca County, MN. Due to land control changes, MMCL requests a permit modification to permanently discharge fill material within 9.78 acres of wetland outside of the original permitted boundary for the purpose of replacing the taconite resources originally proposed but are no longer available and for stormwater management. Additionally, 74.85 acres of previously permitted discharges of fill material within wetlands is either no longer proposed or would not occur in WOTUS. The MMCL modification would result in a total discharge of fill material within 699.87 acres of WOTUS, compared to the 765.3 acres previously authorized.
