What must Inland vessels of 100 GT and over be fitted with for oily mixtures?

Correct Answer: Option A — A fixed system to discharge oily mixtures to a reception facility

Under 33 CFR 155.330, inland vessels of 100 gross tons and over must be equipped with a fixed piping system to facilitate the discharge of oily mixtures to a shore-side reception facility. This ensures compliance with pollution prevention regulations by preventing the overboard discharge of oily bilge water.
