Reference Answer
(a) Categories of Noxious Liquid Substances:
For the purpose of regulation, Noxious Liquid Substances are divided into four categories:
Category X: Substances which, when 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 thus justify the prohibition of discharge into the marine environment.
Category Y: Substances which, when 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 quantity and quality of discharge into the marine environment.
