At what frequency do Coast Guard regulations require a shipboard Oil Pollution Emergency Plan to be reviewed?

Correct Answer: Option A — annually

The Shipboard Oil Pollution Emergency Plan (SOPEP) is a mandatory document under MARPOL Annex I. To ensure the contact information, procedures, and response strategies remain current and effective, USCG and international regulations require that the plan be reviewed and updated on an annual basis by the vessel's master.
