🔍 Key Concepts

• 33 CFR Subchapter O – Pollution focuses on discharges like oil, noxious liquids, and garbage from vessels • Special protections that may apply to the Great Lakes as sensitive or special areas • Which answer choices clearly relate to pollution control versus vessel construction or engineering details

💭 Think About

• Identify which choice actually regulates something being discharged or released from the vessel into the water • Ask yourself: Which options are about preventing contamination of the Great Lakes, and which are about design, route, or machinery that don’t directly address pollution? • Consider how U.S. pollution rules implement or mirror MARPOL garbage provisions for certain protected waters like the Great Lakes

✅ Before You Answer

• Verify which option directly concerns garbage or waste discharges rather than hull strength or cooling systems • Confirm in 33 CFR Subchapter O that requirements are framed as restrictions on discharges (oil, garbage, etc.), not on how frames are built or water is re‑distilled • Eliminate any answer choices that do not clearly tie to pollution prevention requirements for a vessel already operating on the Great Lakes
