The Coast Guard published Sept. 25, 2018, the FY19 Government Initiated Unannounced Exercise (GIUE) requirements for each captain of the port zone, to include sectors and marine safety units. In 2015, the Office of Marine Environmental Response Policy reinvigorated the Coast Guard GIUE program by releasing new GIUE policy that has since been incorporated into the Marine Environmental Response and Preparedness Manual. This policy established consistent exercise design, execution and documentation across the Coast Guard. It also defined the number of GIUEs required at each unit.
