🔍 Key Concepts

• 33 CFR Part 155 and Part 151 – Oil or hazardous material pollution prevention regulations • The difference between temporary containment (like buckets or pans) and discharging into the bilges • Why getting oil into the bilge system is particularly serious for pollution control

💭 Think About

• Which action could more easily lead to oily water being pumped or drained overboard, even by accident? • Look at each choice and ask: where could this oil end up next – overboard, in a controlled tank, or in a contained receptacle to be properly disposed of? • Which practice do the pollution rules try hardest to prevent because it contaminates a whole system instead of a small, contained area?

✅ Before You Answer

• Verify in 33 CFR 155 what is said about keeping oil out of bilges and overboard discharges • Check which options involve collection in containers (buckets/pans) versus sending oil into a system connected to overboard discharge • Confirm which choice would make compliance with oily-water separator and discharge standards in 33 CFR 155.360+ hardest to maintain
