Question 133Safety & Environmental - 1st Asst/Chief

The correct answer is B) and cannot be implemented without approval. The reasoning for this is that when amendments are made to the shipboard oil pollution emergency plan, all revisions must be submitted to the Coast Guard and cannot be implemented without approval. This is because the Coast Guard needs to review and approve any changes to the plan to ensure it continues to meet the regulatory requirements. The other answer choices are incorrect because A) there is no requirement to submit revisions 6 months prior to the end of the approval period, C) revisions do not need to be submitted 1 month prior to the anniversary date, and D) revisions cannot be implemented without immediate Coast Guard approval, even if final approval is received within 6 months.
