(a) Assessment of penalty
Any person who is found by the Secretary, after notice and an opportunity for a hearing in accordance with section 554 of title 5, to have committed an act prohibited by section 1857 of this title shall be liable to the United States for a civil penalty. The amount of the civil penalty shall not exceed $100,000 for each violation. Each day of a continuing violation shall constitute a separate offense. The amount of such civil penalty shall be assessed by the Secretary, or his designee, by written notice. In determining the amount of such penalty, the Secretary shall take into account the nature, circumstances, extent, and gravity of the prohibited acts committed and, with respect to the violator, the degree of culpability, any history of prior offenses, and such other matters as justice may require. In assessing such penalty the Secretary may also consider any information provided by the violator relating to the ability of the violator to pay, Provided, That the information is served on the Secretary at least 30 days prior to an administrative hearing.

(b) Review of civil penalty
Any person against whom a civil penalty is assessed under subsection (a) or against whom a permit sanction is imposed under subsection (g) (other than a permit suspension for nonpayment of penalty or fine) may obtain review thereof in the United States district court for the appropriate district by filing a complaint against the Secretary in such court within 30 days from the date of such order. The Secretary shall promptly file in such court a certified copy of the record upon which such violation was found or such penalty imposed, as provided in section 2112 of title 28. The findings and order of the Secretary shall be set aside by such court if they are not found to be supported by substantial evidence, as provided in section 706(2) of title 5.

(c) Action upon failure to pay assessment
If any person fails to pay an assessment of a civil penalty after it has become a final and unappealable order, or after the appropriate court has entered final judgment in favor of the Secretary, the Secretary shall refer the matter to the Attorney General of the United States, who shall recover the amount assessed in any appropriate district court of the United States. In such action, the validity and appropriateness of the final order imposing the civil penalty shall not be subject to review.

(d) In rem jurisdiction
A fishing vessel (including its fishing gear, furniture, appurtenances, stores, and cargo) used in the commission of an act prohibited by section 1857 of this title shall be liable in rem for any civil penalty assessed for such violation under this section and may be proceeded against in any district court of the United States having jurisdiction thereof. Such penalty shall constitute a maritime lien on such vessel which may be recovered in an action in rem in the district court of the United States having jurisdiction over the vessel.

(e) Compromise or other action by Secretary
The Secretary may compromise, modify, or remit, with or without conditions, any civil penalty which is subject to imposition or which has been imposed under this section.

(f) Subpenas
For the purposes of conducting any hearing under this section, the Secretary may issue subpenas for the attendance and testimony of witnesses and the production of relevant papers, books, and documents, and may administer oaths. Witnesses summoned shall be paid the same fees and mileage that are paid to witnesses in the courts of the United States. In case of contempt or refusal to obey a subpena served upon any person pursuant to this subsection, the district court of the United States for any district in which such person is found, resides, or transacts business, upon application by the United States and after notice to such person, shall have jurisdiction to issue an order requiring such person to appear and give testimony before the Secretary or to appear and produce documents before the Secretary, or both, and any failure to obey such order of the court may be punished by such court as a contempt thereof.
