🔍 Key Concepts
• U.S. water pollution laws such as the Clean Water Act and related Coast Guard regulations
• How the law defines "pollutant" or "discharge of a pollutant"
• The difference, if any, between oil, hazardous substances, and garbage under marine pollution rules
💭 Think About
• Ask yourself: does the law focus on just one type of contaminant, or does it group several harmful materials together as pollution?
• Consider whether each listed item (oil, hazardous substances, garbage) can legally trigger reporting requirements, fines, or cleanup actions if discharged into U.S. waters.
• Think about MARPOL and U.S. regulations: which of these materials have specific discharge limitations or prohibitions at sea?
✅ Before You Answer
• Verify whether oil is specifically regulated as a pollutant under U.S. and international maritime law.
• Verify whether hazardous substances (chemicals, toxic cargoes, etc.) are treated as pollutants when released into water.
• Verify whether garbage (plastics, food waste, domestic refuse) is covered under marine pollution rules and subject to discharge restrictions.
