According to Code of Federal Regulations (33 CFR 151), who is responsible for insuring that a ship is not operated unless a waste management plan is utilized?

Correct Answer: Option B — Vessel's Master

33 CFR 151.57 places the ultimate responsibility on the Master of the vessel to ensure that a Waste Management Plan is implemented and followed. This ensures that all garbage handling, storage, and disposal procedures comply with MARPOL Annex V requirements, preventing pollution of the marine environment by shipboard waste.
