NWO-2024-02005-PIE (Previously NWO-2016-02372-PIE)

Expiration date: 2/3/2025

The Corps initially reviewed the Prospectus for the Northland Wildlife Mitigation Bank (Mitigation Bank) site (previously NWO-2016-02372-PIE) and issued a Public Notice on April 24, 2018. After evaluating the proposal according to the Mitigation Rule (33 CFR 332) and considering public comments, it was determined that the Mitigation Bank had 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). As a result of the review, the Sponsor was authorized to prepare a Draft Mitigation Banking Instrument, which outlines the establishment, operation, and management of the proposed Mitigation Bank. The Corps reviewed several versions of the Draft Mitigation Banking Instrument; however, the Sponsor decided to put the proposal on hold. The Sponsor is pursuing the proposal, which requires an additional public notice period as so much time has elapsed since the first public notice. The Corps is soliciting comments on the mitigation proposal to ensure that interested parties are aware that the mitigation proposal is being pursued once again and can provide any comments or concerns. Please note that the Mitigation Bank described herein is not being proposed by the Corps, but by the Sponsor.
