The U.S. Coast Guard was withdrawn from review by the Office of Management and Budget (OMB) its proposed regulation that would have instituted carriage requirements for an automatic identification system (AIS). Reason for the withdrawal is unclear, but it may have had something to do with OMB processing taking more than two months with no end in sight. One should not be surprised to see the AIS provision included in the USCG maritime security rulemaking due for publication in June.
