Question 2644 Deck General

The correct answer is D. An oil tanker may not discharge an oily mixture into the sea from a cargo tank, slop tank, or cargo pump room bilge unless the following condition is present: The oil content of the effluent without dilution does not exceed 15 parts per million, as required by Regulation 34 of MARPOL Annex I. This regulation sets the maximum oil content for any oily mixture discharged from an oil tanker, regardless of location. The other answer choices are incorrect because they do not accurately represent the regulatory requirement for discharging oily mixtures from an oil tanker. Specific "Special Areas" defined in MARPOL are not relevant in this case, and there are no other conditions that would allow for the discharge of oily mixtures exceeding 15 parts per million.
