According to the Pollution Prevention Regulations (33 CFR), who is to make the final decision of when oil transfer may begin?

Correct Answer: Option D — Designated persons in charge of vessel and facility

33 CFR 156.120 establishes that the designated persons-in-charge (PIC) of both the vessel and the facility hold the authority and responsibility to determine when it is safe to begin an oil transfer. This dual-responsibility model ensures that both parties have verified safety conditions before initiating the transfer process.
