Title 33 › CHAPTER 33 — PREVENTION OF POLLUTION FROM SHIPS › § 1907

Last updated Sep 22, 2026|Official source

Summary

It makes it illegal to break the MARPOL Protocol, Annex IV to the Antarctic Protocol, this law, or the rules made under them. The Secretary must work with other countries to find and stop violations. The Secretary must use practical detection and monitoring tools and set up ways to report wrongdoings and collect evidence. If there is evidence of a violation, the Secretary will investigate. The Secretary can issue subpoenas for witnesses and documents, and can ask the Attorney General to get a court to force compliance. After an investigation, the Secretary will take the actions required by the treaties and any other steps that seem appropriate. If another country provided the initial evidence, the Secretary, through the Secretary of State, will tell that country what was done. The Secretary may inspect ships at U.S. ports to check for illegal discharges of harmful substances or illegal garbage disposal. The Secretary may also inspect U.S.-flag ships or ships under U.S. authority at any time. Inspections can be done at the request of another party if that party supplies enough evidence to justify it. If an inspection shows a violation, the officer will report it, the Secretary will notify the ship’s master, and enforcement actions under U.S. law may follow. The Secretary or the Administrator may enforce Annex VI rules, and the Administrator has full authority to enforce regulations 17 and 18 of Annex VI for shore-side violations and other referred matters.

It is unlawful to act in violation of the MARPOL Protocol, Annex IV to the Antarctic Protocol, this chapter, or the regulations issued thereunder. The Secretary shall cooperate with other parties to the MARPOL Protocol or to the Antarctic Protocol in the detection of violations and in enforcement of the MARPOL Protocol and Annex IV to the Antarctic Protocol. The Secretary shall use all appropriate and practical measures of detection and environmental monitoring, and shall establish adequate procedures for reporting violations and accumulating evidence.
(b)Investigations; subpenas: issuance by Secretary, enforcement; action by Secretary; information to party
Upon receipt of evidence that a violation has occurred, the Secretary shall cause the matter to be investigated. In any investigation under this section the Secretary may issue subpenas to require the attendance of any witness and the production of documents and other evidence. In case of refusal to obey a subpena issued to any person, the Secretary may request the Attorney General to invoke the aid of the appropriate district court of the United States to compel compliance. Upon completion of the investigation, the Secretary shall take the action required by the MARPOL Protocol or the Antarctic Protocol and whatever further action he considers appropriate under the circumstances. If the initial evidence was provided by a party to the MARPOL Protocol or the Antarctic Protocol, the Secretary, acting through the Secretary of State, shall inform that party of the action taken or proposed.
(c)Ship inspections; reports to Secretary; additional action
(1)This subsection applies to inspections relating to possible violations of Annex I or Annex II to the Convention, of Article 3 or Article 4 of Annex IV to the Antarctic Protocol, or of this chapter by any seagoing ship referred to in section 1902(a)(2) of this title.

(B)to comply with a request from a party to the MARPOL Protocol or the Antarctic Protocol for an investigation as to whether the ship may have discharged a harmful substance anywhere in violation of the MARPOL Protocol or Annex IV to the Antarctic Protocol. An investigation may be undertaken under this clause only when the requesting party has furnished sufficient evidence to allow the Secretary reasonably to believe that a discharge has occurred.
If an inspection under this subsection indicates that a violation has occurred, the investigating officer shall forward a report to the Secretary for appropriate action. The Secretary shall undertake to notify the master of the ship concerned and, acting in coordination with the Secretary of State, shall take any additional action required by Article 6 of the Convention.

(e)Harmful substance or garbage disposal inspections; covered ships; enforcement actions
(1)The Secretary may inspect at any time a ship of United States registry or nationality or operating under the authority of the United States to which the MARPOL Protocol or the Antarctic Protocol applies to verify whether the ship has discharged a harmful substance or disposed of garbage in violation of those Protocols or this chapter.
(2)If an inspection under this subsection indicates that a violation of the MARPOL Protocol, of Annex IV to the Antarctic Protocol, or of this chapter has occurred the Secretary may undertake enforcement action under section 1908 of this title.
(f)Inspections; enforcement
(1)The Secretary may inspect a ship to which this chapter applies as provided under section 1902(a)(5) of this title, to verify whether the ship is in compliance with Annex VI to the Convention and this chapter.

(3)Notwithstanding subsection (b) and paragraph (2) of this subsection, the Administrator shall have all of the authorities of the Secretary, as specified in subsection (b) of this section, for the purposes of enforcing regulations 17 and 18 of Annex VI to the Convention to the extent that shoreside violations are the subject of the action and in any other matter referred to the Administrator by the Secretary.
