32 C.F.R. § 536.123
For admiralty claims arising within the United States under the provisions of the Limitation of Shipowners' Liability Act, 46 U.S.C. app. 181-188, in cases alleging injury or loss due to negligent operation of its vessel, the United States may limit its liability to the value of its vessel after the incident from which the claim arose. The act requires filing of an action in federal District Court within six months of receiving written notice of a claim. Therefore, USARCS, or the Chief Counsel, U.S. Army Corps of Engineers (COE), or his designee, must be notified within 10 working days of the receipt of any maritime claim arising in the United States or on the high seas out of the operation of an Army vessel, including pleasure craft owned by the United States. USARCS or Chief Counsel, COE will coordinate with the Department of Justice (DOJ) as to whether to file a limitation of liability action.
