A person who knowingly violates the MARPOL Protocol, Annex IV to the Antarctic Protocol, this chapter, or the regulations issued thereunder commits a class D felony. In the discretion of the Court, an amount equal to not more than ½ of such fine may be paid to the person giving information leading to conviction.

A person who is found by the Secretary, or the Administrator as provided for in this chapter, after notice and an opportunity for a hearing, to have—

(1) violated the MARPOL Protocol, Annex IV to the Antarctic Protocol, this chapter, or the regulations issued thereunder shall be liable to the United States for a civil penalty, not to exceed $25,000 for each violation; or

(2) made a false, fictitious, or fraudulent statement or representation in any matter in which a statement or representation is required to be made to the Secretary, or the Administrator as provided for in this chapter, under the MARPOL Protocol, Annex IV to the Antarctic Protocol, this chapter, or the regulations thereunder, shall be liable to the United States for a civil penalty, not to exceed $5,000 for each statement or representation.

The Secretary, or the Administrator as provided for in this chapter, may compromise, modify, or remit, with or without conditions, any civil penalty which is subject to assessment or which has been assessed under this section. If any person fails to pay an assessment of a civil penalty after it has become final, the Secretary, or the Administrator as provided for in this chapter, may refer the matter to the Attorney General of the United States for collection in any appropriate district court of the United States.

A ship operated in violation of the MARPOL Protocol, Annex IV to the Antarctic Protocol, this chapter, or the regulations thereunder is liable in rem for any fine imposed under subsection (a) or civil penalty assessed pursuant to subsection (b), and may be proceeded against in the United States district court of any district in which the ship may be found.

If any ship subject to the MARPOL Protocol, Annex IV to the Antarctic Protocol, or this chapter, its owner, operator, or person in charge is liable for a fine or civil penalty under this section, or if reasonable cause exists to believe that the ship, its owner, operator, or person in charge may be subject to a fine or civil penalty under this section, the Secretary of the Treasury, upon the request of the Secretary, shall refuse or revoke the clearance required by section 60105 of title 46. Clearance may be granted upon the filing of a bond or other surety satisfactory to the Secretary.

Notwithstanding subsection (a), (b), or (d) of this section, if the violation is by a ship registered in or of the nationality of a country party to the MARPOL Protocol or the Antarctic Protocol, or one operated under the authority of a country party to the MARPOL Protocol or the Antarctic Protocol, the Secretary, or the Administrator as provided for in this chapter acting in coordination with the Secretary of State, may refer the matter to the government of the country of the ship’s registry or nationality, or under whose authority the ship is operating for appropriate action, rather than taking the actions required or authorized by this section.

Any penalty collected under subsection (a) or (b) that is not paid under that subsection to the person giving information leading to the conviction or assessment of such penalties shall be deposited in the Abandoned Seafarers Fund established under section 11113 of title 46.
