Question 1 of 27070

Pollution of the waterways may result from the discharge of which item(s)?

🔍 Key Concepts

• 33 CFR Part 151 – Control of pollution from ships (garbage, plastics, oily mixtures) • Differences between oil pollution, garbage, and sewage regulations • Meaning of "may result" in an exam question vs. specific concentration limits

💭 Think About

• For each option, ask yourself: if this were discharged into navigable waters, could it create any kind of prohibited pollution situation under U.S. or international rules? • Think about whether the law is concerned only with large amounts or if even small concentrations / certain types of waste are regulated. • Consider whether the question is testing a specific numerical limit, or your general understanding that multiple kinds of discharges are controlled.

✅ Before You Answer

• Verify that oil discharges are regulated even in very low concentrations, not just in large spills. • Recall that sewage has its own discharge limitations and treatment requirements under regulations. • Confirm that garbage/galley trash (especially plastics and food waste) is covered under MARPOL/33 CFR 151 garbage regulations.
