§155.370. Oily mixture (bilge slops)/fuel oil tank ballast water discharges on oceangoing ships of 10,000 gross tons and above and oceangoing ships of 400 gross tons and above that carry ballast water in their fuel oil tanks.
33 C.F.R. § 155.370
Except as provided in paragraph (a)(5) of this section, no person may operate an oceangoing ship of 10,000 gross tons and above, or any oceangoing ship of 400 gross tons and above, that carries ballast water in its fuel oil tanks, unless it has—
Approved 15 ppm oily-water separating equipment for the processing of oily mixtures from bilges or fuel oil tank ballast;
A bilge alarm; and
A means for automatically stopping any discharge of oily mixture when the oil content in the effluent exceeds 15 ppm.
For equipment installed after 2004 to be approved under paragraph (a) of this section, it must meet current standards in 46 CFR part 162, subpart 162.050 by the date set forth in paragraphs (a)(4)(i) and (a)(4)(ii) of this section, unless the equipment is installed on a ship constructed before 2005 and it would be unreasonable or impracticable to meet those current standards.
A ship entering international service for the first time since 2004, must comply with the requirements of paragraph (a)(4) of this section by the date of its initial survey prior to receiving its International Oil Pollution Prevention (IOPP) certificate.
Any ship, other than a ship described in paragraph (a)(4)(i) of this section, must comply with the requirements of paragraph (4) of this section by the date of the ship's first drydock after October 13, 2009.
Any ship certified under the International Code of Safety for High-Speed Craft engaged on a scheduled service with a turn-around time not exceeding 24 hours and covering also non-passenger/cargo-carrying relocation voyages for these ships need not be provided with oil filtering equipment. These ships must be fitted with an oily bilge water holding tank having a volume adequate for the total retention onboard of the oily bilge water. All oily bilge water must be retained onboard for subsequent discharge to reception facilities.
No person may operate a ship under this section unless it is fitted with an oil residue (sludge) tank or tanks of adequate capacity to receive the oil residue that cannot be dealt with otherwise.
In new ships such tanks shall be designed and constructed to facilitate cleaning and the discharge of the oil residue to reception facilities. Existing ships shall comply with this requirement as far as reasonable and practicable.
Tanks used for oily mixtures on ships certificated under 46 CFR Chapter I shall meet the requirements of 46 CFR 56.50-50(h) for isolation between oil and bilge systems.
Ships subject to this section must—
Be provided with a designated pump for disposal that is capable of taking suction from the oil residue (sludge) tank(s); and
Have no discharge connections to the bilge system, oily bilge water holding tank(s), tank top or oily water separators except that the tank(s) may be fitted with drains, with manually operated self-closing valves and arrangements for subsequent visual monitoring of the settled water, that lead to an oily bilge water holding tank or bilge well, or an alternative arrangement, provided such arrangement does not connect directly to the bilge piping system.
No person may operate a ship under this section unless it is equipped with a pipeline to discharge oily mixtures to a reception facility.
This section does not apply to a barge that is not equipped with an installed bilge pumping system for discharge into the sea.
This section does not apply to a fixed or floating drilling rig or other platform, except as specified in § 155.400(a)(2).
