Title 33 › CHAPTER 9 — PROTECTION OF NAVIGABLE WATERS AND OF HARBOR AND RIVER IMPROVEMENTS GENERALLY › SUBCHAPTER I — IN GENERAL › § 408
You must not take over, use, change, move, break, or remove any sea wall, bulkhead, jetty, dike, levee, wharf, pier, buoy, tide gauge, or other structure the United States built to protect or mark its waterways. You also must not attach vessels to them in a way that blocks or harms them, or take stones or materials for ballast. The Secretary of the Army can allow temporary use if the Chief of Engineers agrees and it won’t hurt the public interest. The Secretary can also allow permanent changes or use if, after the Chief’s recommendation, it won’t harm the public interest or reduce the work’s usefulness. If the action needs a NEPA environmental review, the Corps of Engineers and the Secretary must try to handle their review at the same time as the NEPA review. The Corps should join as a cooperating agency unless it will not comment, and it can use environmental documents made by the lead federal agency. The Secretary must coordinate any other required reviews and may use Corps documents that are current and apply. The Secretary may accept money from non-federal public or private groups to help evaluate a proposed change and to hold a pre-application meeting. The Secretary must give clear, consistent guidance, meet with applicants on request, tell them within 30 days if an application is complete, and decide or give a decision schedule within 90 days of a complete application. If the schedule goes past 120 days, the Secretary must explain the delay to two Congressional committees. “Work” excludes unimproved land the Secretary finds will not affect the project’s function.
