In accordance with federal regulations under 33CFR Subchapter O, for U.S non- oceangoing ships, what is the required means for preventing pollution by oil as it pertains to handling bilge slops?

Correct Answer: Option A — The non-oceangoing ship is required to retain onboard all oily mixtures either in the bilges or in a slops tank, and it is required to be equipped to discharge these mixtures to a reception facility.

Under 33 CFR 151.09, non-oceangoing ships are not subject to the same overboard discharge requirements as oceangoing vessels. They must retain all oily mixtures onboard in bilges or dedicated slop tanks, ensuring that these pollutants are transferred to an approved shore-side reception facility, thereby preventing any unauthorized discharge into the water.
