The Department of the Treasury's Office of Foreign Assets Control ("OFAC") is amending 31 CFR chapter V to replace the list of persons (which includes individuals and entities) with whom transactions and dealings are prohibited by the various economic sanctions programs administered by OFAC that appears at Appendix A to 31 CFR chapter V with information on how to obtain up-to-date lists of such persons on OFAC's Web site or by other means. OFAC also is removing Appendix B to 31 CFR chapter V, which includes the names of certain blocked vessels. In addition, OFAC is amending its regulations for a number of the sanctions programs it administers to revise references to Appendix A and to remove references to Appendix B. Finally, OFAC is amending the Iranian Transactions Regulations, by republishing in alphabetical order the entire list of persons identified in Appendix A to 31 CFR Part 560, to reflect changes to the list since that appendix was last published.
