Proposed RuleSIGNIFICANT · E.O. 12866Defense DepartmentEngineers CorpsEnvironmental Protection Agency

Updated Definition of “Waters of the United States”

The purpose of this supplemental notice of proposed rulemaking is for the U.S. Environmental Protection Agency (EPA) and the Department of the Army ("the agencies") to supplement and seek additional comment on certain aspects of an earlier proposal, published on November 20, 2025, to revise the regulations defining the scope of waters federally covered under the Clean Water Act in light of the U.S. Supreme Court's 2023 decision in Sackett v. Environmental Protection Agency. As stated in the agencies' November 20, 2025 Notice of Proposed Rulemaking (NPRM), the agencies intend for this rulemaking to provide greater regulatory certainty and increase Clean Water Act program predictability and consistency by clarifying the definition of "waters of the United States." After consideration of the public comments received on the NPRM, the agencies are issuing this notice to supplement the NPRM with additional regulatory options on certain aspects of the proposed rule.

Proposed RuleDefense DepartmentEngineers Corps

Restricted Area: Naval Weapons Station Seal Beach

The U.S. Army Corps of Engineers (Corps) is proposing to revise the existing regulations for a restricted area within Naval Weapons Station Seal Beach (NWSSB). The Department of the Navy requested amendment of a restricted area located within NWSSB, in the City of Seal Beach, Orange County, California (33.7334 Latitude/- 118.0953 Longitude). NWSSB is the primary West Coast installation for the supply of munitions to U.S. Navy vessels. Following an extensive project to reconfigure Anaheim Bay, including the creation of a new ammunition pier and the relocation of a public boating channel, the Department of the Navy requested the Corps modify the existing restricted area regulations to protect the public from navigational and operational hazards, and to protect government assets, missions, and the base population in general.
