This Marine Safety Information Bulletin (MSIB) serves to notify the maritime industry of the revised applicability criteria to maintain a garbage record book (GRB). These changes are a result of the International Maritime Organization’s Marine Environment Protection Committee (MEPC) adoption of amendments to MARPOL Annex V Regulation 10 – Placards, garbage management plans and garbage record-keeping.
