Definitions:

Marpol I dirty ballast water

Dirty ballast is created when seawater is pumped into empty fuel tanks for the purpose of increasing ship stability. The seawater mixes with residual fuel producing “dirty” ballast. Pollutants in dirty ballast may include residual fuel, fuel additives (e.g., biocides), oil and grease, petroleum hydrocarbons, and metals (e.g., copper, nickel, silver, and zinc). (http://www.globalsecurity.org/military/systems/ship/shipbreaking-green.htm 14.Dec. 2007)

Marpol I tank washing (slops)

When switching cargoes, tankers are often required to clean their cargo tanks of residue left over from previous cargo. The remaining oil and water left over from a tank washing is typically stored in one or more slop tanks. Various lubrication and other oils spilled during ship operations may also be stored in the slop tanks. (www.marineornithology.org 14.Dec. 2007)

Marpol I oily mixtures containing chemicals

Any mix of oils additionally contaminated by one or more chemicals.

Marpol I scale and sludge from tanker cleaning

The solid and semi-liquid deposits removed from the walls and floor of tanks during tanker cleaning

Marpol I oily bilge water

Water contaminated by oil that builds up in the bottom of a ship's bilge. (adapted McGraw-Hill Zanichelli Dizionario Enciclopedico Scientifico e Tecnico Inglese-Italiano Italiano-Inglese, Zanichelli, Bologna, 1998)

Marpol I sludge from fuel oil purifier

semi-liquid deposits removed from fuel oil purifier

Marpol II Category X

Noxious Liquid Substances which, if discharged into the sea from tank cleaning or deballasting operations, are deemed to present a major hazard to either marine resources or human health and, therefore, justify the prohibition of the discharge into the marine environment;

Marpol II Category Y

Noxious Liquid Substances which, if discharged into the sea from tank cleaning or deballasting operations, are deemed to present a hazard to either marine resources or human health or cause harm to amenities or other legitimate uses of the sea and therefore justify a limitation on the quality and quantity of the discharge into the marine environment;

Marpol II Category Z

Noxious Liquid Substances which, if discharged into the sea from tank cleaning or deballasting operations, are deemed to present a minor hazard to either marine resources or human health and therefore justify less stringent restrictions on the quality and quantity of the discharge into the marine environment;

Marpol II Other substances

Substances which have been evaluated and found to fall outside Category X, Y or Z because they are considered to present no harm to marine resources, human health, amenities or other legitimate uses of the sea when discharged into the sea from tank cleaning of deballasting operations. The discharge of bilge or ballast water or other residues or mixtures containing these substances are not subject to any requirements of MARPOL Annex II;

Marpol IV sewage 1

drainage and other wastes from any form of toilets and urinals;

Marpol IV sewage 2

drainage from medical premises (dispensary, sick bay, etc) via wash basins, wash tubs and scuppers located in such premises;

Marpol IV sewage 3

drainage from spaces containing living animals;

Marpol IV sewage 4

other waste waters when mixed with the drainages defined above;

Marpol V garbage

Garbage means all kinds of victual, domestic and operational waste excluding fresh fish and parts thereof, generated during the normal operation of the ship and liable to be disposed of continuously or periodically except those substances which are defined or listed in other Annexes to the present MARPOL Convention.
