The correct answer is B) a list of personnel duty assignments. The Shipboard Oil Pollution Emergency Plan (SOPEP) is required to have specific appendices, but a list of personnel duty assignments is not one of them. The SOPEP must include appendices with a list specifying who will be responsible for informing the parties listed and the priority in which they must be notified (A), a list of agencies or officials in regularly visited ports (C), and a list of agencies or officials of Coastal State administrations responsible for receiving and processing incident reports (D). However, a list of personnel duty assignments is not a required appendix for the SOPEP.
