The District Engineer has received a prospectus from the Sponsor, Tetonka LLP, titled: “Mitigation Bank Prospectus – Sourdough Flats”, hereon referred to as the Prospectus. The Corps is soliciting comments on the Prospectus. The Prospectus described herein is not being proposed by the Corps, but by the Sponsor. The Corps will evaluate the Prospectus according to the requirements of the Mitigation Rule (33 CFR 332) to determine if the Prospectus has the potential to produce compensatory mitigation suitable to offset unavoidable impacts to waters of the United States authorized through the issuance of Department of the Army (DA) permits pursuant to section 404 of the Clean Water Act (33 U.S.C. 1344) and/or sections 9 or 10 of the Rivers and Harbors Act of 1899 (33 U.S.C. 401, 403).

Expiration date: 8/5/2024

The purpose of the proposed action is to remove BNSF Railway Company (BNSF) Bridge 2001-518.9 from the Big Sioux River due to a significant storm event that caused the structure, managed by the USACE Omaha District, to be damaged and dislodged from the pier in the center of the river. BNSF proposes to construct temporary access for bridge removal activities through the North Sioux City Right Bank Levee on the west side; and separately construct temporary access on the east side. BNSF proposes to maintain levee continuity during levee excavation, by constructing a ring levee in a manner to preserve flood protection for North Sioux City should a moderate or major flood event occur on the Big Sioux River during levee excavation operations and access to the river for cleanup and removal of the storm damaged structure within the river. Upon completion of the ring levee the access path and causeway will be constructed in the Big Sioux River. BNSF’s plans for the new bridge replacement / construction will be submitted to USACE and the local levee Sponsors in a future separate Section 408 request and Section 404 application. Only project elements that would alter the Federal Project are within the review scope for the Section 408 permission request.

Expiration date: 8/5/2024

The District Engineer, Omaha, is evaluating a permit application from Mountrail County for a 6-mile road reconstruction project on County Road 11 centered on Latitude 48.167466° North, Longitude -102.148896° West. The project would consist of widening the existing embankment to increase existing 1-foot-wide shoulders to 5 feet, extending culverts, and modifying the vertical profile to increase sight distance. The project would result in a permanent loss of 0.90-acre of wetlands and temporary impacts to 0.80-acre. Project impacts are proposed to be offset through purchase of mitigation credits. Work would occur in Sections 1, 2, 11, and 12, Township 154 North, Range 89 West, and Sections 11-14, 23-26, and 35-36, Township 155 North, Range 89 West, Mountrail County, North Dakota.

Expiration date: 7/29/2024

Central Public Power & Irrigation District (CNPPID) is proposing to remove sediment from upstream of its Supply Canal Diversion Dam and deposit it downstream into the Platte River when flow is greater than 150 cfs. The proposed project will also include dredging and discharging into temporary off-site containment areas when the Platte River flow is less than 150 cfs. Sediment from the East Dredge Containment Area will be mechanically discharged into the Platte River when flows are conductive. To improve conveyance downstream of the Diversion Dam, the Platte River channel will be re-directed with the installation of a wing dike to the East Dredge Containment Area for managed mechanical discharge. The proposed wing dike will be 700-foot-long with a 15-foot top width. The wing dike will direct north gate flow from 0 to 3,000 cfs to the East Dredge Containment Area along the south bank of the Platte River via a 1,850-foot-long, 90-foot-wide constructed diversion channel. The wing dike will have a variable bottom width not to exceed 60 feet. The East Dredge Containment Area will also be expanded to allow for greater on-site containment. Annual sand aggradation is anticipated to occur within the constructed channel. To maintain flows, annual mechanized maintenance of the channel will be required to remove aggraded sand/sediment and maintain a 90-foot bottom width and a 0.1% slope, as the depth varies along the channel.
