Question 87Safety & Environmental - Assistant Engineer

The correct answer is D) All of the above. This is because the regulations governing the overboard discharge of vessel sewage at sea state the following: 1) The vessel may discharge disinfected and comminuted sewage into the sea, from an approved system, only if the vessel is more than three nautical miles from the nearest land (option A). 2) The vessel must have an approved sewage plant to legally discharge sewage at sea (option B). 3) The vessel may discharge sewage into the sea, from an approved system which is not comminuted or disinfected, only if the vessel is more than 12 nautical miles from the nearest land (option C). Therefore, all three statements are true concerning the overboard discharge of vessel sewage at sea.
