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.

33 CFR 151.10 requires non-oceangoing vessels to retain oily mixtures onboard for discharge to an approved reception facility. Unlike oceangoing vessels, they are not required to be fitted with 15 ppm oily-water separators, as the regulatory focus is on total containment and shore-side disposal of all oily bilge slops.
