Sec. 151.05  Definitions.

    As used in this subpart--
    Act means the Act to Prevent Pollution from Ships, as amended (33 
U.S.C. 1901-1911).
    Antarctica means the area south of 60 degrees south latitude.
    Cargo associated wastes means all materials which have become wastes 
as a result of use on board a ship for cargo stowage and handling. Cargo 
associated wastes include, but are not limited to dunnage, shoring, 
pallets, lining and packing materials, plywood, paper, cardboard, wire, 
and steel strapping.
    Clean ballast means the ballast in a tank which, since oil was last 
carried therein, has been so cleaned that effluent therefrom, if it were 
discharged from a ship that is stationary into clean calm water on a 
clear day would not produce visible traces of oil on the surface of the 
water or adjoining shorelines or cause a sludge or emulsion to be 
deposited beneath the surface of the water or upon adjoining shorelines. 
If the ballast is discharged through an oil discharge monitoring and 
control system approved by the government of the country under whose 
authority the ship is operating, evidence based on such a system, to the 
effect that the oil content of the effluent does not exceed 15 parts per 
million (ppm) is determinative that the ballast is clean.
    Commandant means Commandant, U.S. Coast Guard.
    Discharge means any release, however caused, from a ship and 
includes any escape, disposal, spilling, leaking, pumping, emitting or 
emptying. It does not include--
    (1) Dumping within the meaning of the Convention on the Prevention 
of Marine Pollution by Dumping of Wastes and Other Matter, done at 
London on 13 November 1972; or
    (2) Release of oil or oily mixtures directly arising from the 
exploration, exploitation and associated off-shore processing of sea-bed 
mineral resources.
    Discharge, as defined by MARPOL 73/78 in relation to harmful 
substances or effluent containing such substances, means any release 
however caused from a ship, and includes any escape, disposal, spilling, 
leaking, pumping, emitting or emptying. It does not include--
    (1) Dumping within the meaning of the Convention on the Prevention 
of Marine Pollution by Dumping of Wastes and Other Matter, done at 
London on November 13, 1972; or
    (2) The release of harmful substances directly arising from the 
exploration, exploitation, and associated offshore processing of seabed 
mineral resources; or
    (3) The release of harmful substances for purposes of legitimate 
scientific research relating to pollution abatement or control.
    Dishwater means the liquid residue from the manual or automatic 
washing

that any food particles adhering to them would not normally interfere 
with the operation of automatic dishwashers.

spaces on board a ship, except victual wastes.
    Existing ship means a ship that is not a new ship.

excluding fresh fish and parts thereof, generated during the normal 
operation of the ship and liable to be disposed of continuously or 
periodically, except dishwater, graywater, and those substances that are

Lawrence River west of a rhumb line drawn from Cap des Rosiers to West 
Point, Anticosti Island, and, on the north side of Anticosti Island, the 
meridian of longitude 63 degrees west.
    Harmful substance means any substance which, if introduced into the 
sea, is liable to create hazards to human health, harm living resources 
and marine life, damage amenities, or interfere with other legitimate 
uses of the sea, and includes any substance subject to control by MARPOL 
73/78.

least 25 mPa.s at 20 [deg]C and at least 25 mPa.s at the time they are 
unloaded, high viscosity Category B NLSs, and high viscosity Category C 
NLSs.
    Instantaneous rate of discharge of oil content means the rate of 
discharge of oil in liters per hour at any instant divided by the speed

oil refuse, oil residue, and refined products, and, without limiting the 
generality of the foregoing, includes the substances listed in Appendix

brittle to soft and elastic. Plastics are used for a variety of marine 
applications including, but not limited to: food wrappings, products for

ship after the NLS is discharged to the consignee, including but not 
limited to puddles on the tank bottom and in sumps, clingage in the 
tanks, and substance remaining in the pipes; or
    (3) Any material contaminated with Category A, B, C, or D NLS cargo, 
including but not limited to bilge slops, ballast, hose drip pan 
contents, and tank wash water.
    Segregated ballast means the ballast water introduced into a tank 
that is completely separated from the cargo oil and fuel oil system and 
that is permanently allocated to the carriage of ballast or to the 
carriage of ballast or cargoes other than oil or noxious substances as 
variously defined in the Annexes of MARPOL 73/78.
    Ship means a vessel of any type whatsoever, operating in the marine 
environment. This includes hydrofoils, air-

[[Page 265]]

cushion vehicles, submersibles, floating craft whether self-propelled or

    Shipboard oil pollution emergency plan means a plan prepared, 
submitted, and maintained according to the provisions of Sec. Sec. 
151.26 through 151.28 of this subpart for United States ships or 
maintained according to the provisions of Sec. 151.29(a) of this 
subpart for foreign ships operated under the authority of a country that 
is party to MARPOL 73/78 or carried on board foreign ships operated 
under the authority of a country that is not a party to MARPOL 73/78, 
while in the navigable waters of the United States, as evidence of 
compliance with Sec. 151.21 of this subpart.
    Solidifying NLS means a Category A, B, or C NLS that has a melting 
point--
    (1) Greater than 0 [deg]C but less than 15 [deg]C and a temperature, 
measured under the procedure in 46 CFR 153.908(d), that is less than 5 
[deg]C above its melting point at the time it is unloaded; or
    (2) 15 [deg]C or greater and a temperature, measured under the 
procedure in 46 CFR 153.908(d), that is less than 10 [deg]C above its 
melting point at the time it is unloaded.
    Special area means a sea area, where for recognized technical 
reasons in relation to its oceanographical and ecological condition and 
to the particular character of the traffic, the adoption of special 
mandatory methods for the prevention of sea pollution by oil, NLSs, or

    Terminal means an onshore facility or an offshore structure located 
in the navigable waters of the United States or subject to the 
jurisdiction of the United States and used, or intended to be used, as a 
port or facility for the transfer or other handling of a harmful 
substance.
    Note: The Coast Guard interprets commercial fishing facilities, 
recreational boating facilities, and mineral and oil industry shorebases 
to be terminals for the purposes of Annex V of MARPOL 73/78, since these 
facilities normally provide wharfage and other services, including 
garbage handling, for ships.
    U.S. inspected ships means those ship required to be inspected and 
certificated under 46 CFR 2.01-7.
    Victual waste means any spoiled or unspoiled food waste.
