Except as provided in section 1903(b)(1) of this title, the Secretary shall designate those persons authorized to issue on behalf of the United States the certificates required by the MARPOL Protocol. A certificate required by the MARPOL Protocol shall not be issued to a ship which is registered in or of the nationality of a country which is not a party to the MARPOL Protocol.
An inspection conducted under subsection (c)(2) of this section is limited to verifying whether or not a valid certificate is onboard, unless clear grounds exist which reasonably indicate that the condition of the ship or its equipment does not substantially agree with the particulars of its certificate. This section shall not limit the authority of any official or employee of the United States under any other treaty, law, or regulation to board and inspect a ship or its equipment.
A person whose ship is subject to a detention order under this section may petition the Secretary, in the manner prescribed by regulation, to review the detention order. Upon receipt of a petition under this subsection, the Secretary shall affirm, modify, or withdraw the detention order within the time prescribed by regulation.
