Title 33 › Chapter CHAPTER 33— - PREVENTION OF POLLUTION FROM SHIPS › § 1902

Last updated Apr 6, 2026|Official source

Summary

The law makes international rules about pollution from ships apply to U.S. ships wherever they are and to many foreign ships when they enter U.S. waters or areas the U.S. manages. It covers oil and noxious liquid rules (Annexes I and II) when foreign ships are in U.S. navigable waters, garbage rules (Annex V) in U.S. navigable waters and the exclusive economic zone, and air pollution rules (Annex VI) for ships in U.S. ports, shipyards, internal waters, in U.S. navigable waters or EEZ, in designated emission control areas, or other areas the federal environmental official and the Secretary and affected States identify. U.S. ports and terminals are also covered by rules the government makes. Any other ship is covered as far as it can be boarded and inspected under U.S. law. Military ships and ships excluded by certain international agreements are mostly not covered, except that the garbage rules still apply except for ships the military says cannot meet them for design or mission reasons. Plastics are always banned from being dumped. Some nonplastic garbage can be dumped only if it meets size, shredding, or weighting rules and only beyond set distances from land (3 nautical miles or 12 nautical miles, or 25 nautical miles if no garbage-processing gear). Safety, wartime, and emergency exceptions exist and must be reported. The Navy had set dates to meet special-area rules for many ships and must publish standards and lists for certain ships. The Navy must also work on shipboard waste technologies and limit certain plastic and buoyant garbage discharges before entering port. The President may pause some deadlines for up to one year and must report waivers to Congress. Federal departments must set standards for excluded ships so they act as consistently as possible with the international rules. Nothing here limits lawful navigation rights.
