Among solid waste categories, which requires the greatest minimum separation distance?

• A. >12NM shredded metal & glass
• B. >3NM pulped
• C. >25NM non-floating unprocessed garbage
• D. All categories have the same distance

Answer: (C)

Regulations set separation distances based on the environmental risk of each waste type. Non-floating unprocessed garbage poses the greatest long‑term threat because it sinks and remains in the environment, potentially smothering seabed habitats and persisting for a long time. To reduce the chance that this waste ends up impacting coastal ecosystems, the rule requires the largest buffer from land—more than 25 nautical miles. In contrast, waste that is shredded or pulped is more readily dispersed or degraded and thus carries a lower long‑term risk, allowing smaller separation distances. So the greatest minimum separation distance is for non-floating unprocessed garbage, reflecting its higher potential for enduring environmental impact.
