Question 121Safety & Environmental - Assistant Engineer

The correct answer is A) annually only. Coast Guard regulations require a shipboard oil pollution emergency plan to be reviewed annually. This is specified in 33 CFR 155.1030(c), which states that the plan must be reviewed and updated as necessary, but at a minimum, it must be reviewed annually. The other options are incorrect because the regulations do not mandate a review on a biennial (every 2 years), quad-annual (every 4 years), or 5-year basis. The annual review requirement is the only option that aligns with the applicable Coast Guard regulation.
