Proposal To Reissue and Modify Nationwide Permits

Document 2025-11190 is a Proposed Rule published by the Department of Defense in the Federal Register on June 18, 2025. Nationwide Permits (NWPs) are issued by the U.S. Army Corps of Engineers (Corps) to authorize categories of activities under Section 404 of the Clean Water Act and Section 10 of the Rivers and Harbors Act of 1899 that have no more than minimal individual and cumulative adverse environmental effects. The Corps is proposing to reissue its existing NWPs and associated general conditions and definitions, with some modifications. The Corps is proposing to issue one new NWP. The proposed new NWP would authorize activities to improve the passage of fish and other aquatic organisms through aquatic ecosystems. In addition, the Corps is proposing to modify some other NWPs to simplify and clarify those NWPs. The proposed modifications to the NWPs general conditions, and definitions are intended to reduce burdens on the regulated public and continue to comply with the statutory requirement that NWPs authorize only activities with no more than minimal individual and cumulative adverse environmental effects. The Corps is proposing to modify two of the 2021 NWPs (i.e., NWP 48 for commercial shellfish mariculture activities and NWP 56 for finfish mariculture activities) to address litigation on those NWPs. The Corps is requesting comment on all aspects of these proposed NWPs.
