Question 2549 Deck General

The correct answer is B) a USCG approved shipboard oil pollution emergency plan. U.S. regulations require all tankships of 150 GT and above and all other ships of 400 GT and above to prepare and maintain a USCG approved shipboard oil pollution emergency plan. This requirement is outlined in the Oil Pollution Act of 1990, which mandates that vessels have a plan in place to respond effectively to oil spills or other pollution incidents. The other answer choices are incorrect because they do not reflect the actual regulatory requirements. A vapor recovery procedures plan, oil discharge plan, and synthetic plastic discharge plan are not mandated for these vessel types under U.S. regulations.
