Minntac East Pit Layback

Expiration date: 7/31/2026

United States Steel Corporation (USS) is requesting a DA permit for a 112-acre mine pit expansion within wetlands and a 463 linear-foot segment of Parkville Creek. The mine expansion would occur within the southern edge of the existing East Pit near the abandoned Parkville neighborhood and would provide the applicant with an estimated 112 million long tons (LT) of ore over a 4-year period, accounting for an estimated 55 percent (28 million LT/yr) of the total ore movement for the facility. This expansion would extend the life of the Minntac mine to year 2044. The proposed work is expected to contain an estimated 23 million LT of surface and an estimated 68 million LT of waste rock. Existing stockpiles would be used to accommodate the overburden and waste rock, and new dumps would not be needed to accommodate the material. The mine expansion would result in the permanent discharge of dredged and fill material into approximately 3,846 square feet of Parkville Creek and into 15.22 acres of wetlands as well as the indirect impact to 0.67-acre of wetlands due to fragmentation.

200th Street Wetland Bank

Expiration date: 7/30/2026

The proposal includes restoring a wetland and upland prairie complex within a 73.7-acre site. Approximately 35.6 acres within the site have been cultivated with corn and soybeans for over 20 years and approximately 31 acres within the site have been enrolled in the Conservation Reserve Program (CRP) since 2021. The CRP area would be bought prior to recording the conservation easement necessary for the wetland mitigation bank. Private drain tiles within the site appear to have fully drained historical wetlands. Specific objectives of the bank involve reestablishing 29.9 acres of wetland, including 5.4 acres of deep marsh, 12.3 acres of shallow marsh, and 12.2 areas of wet meadow communities, to generate approximately 36.8250 wetland mitigation credits. Hydrology is proposed to be restored within the site by breaking drain tiles, creating embankments, and installing new outlets at historical overflow elevations (see Figure 8 in the prospectus). Vegetation is proposed to be restored by treating and managing invasive species and seeding with native vegetation in both the wetland and upland areas.
