Draft amendments to revise the MARPOL regulations on the prevention of air pollution from ships were agreed by the IMO Sub-Committee on Bulk Liquids and Gases (BLG) when it met last week (4-8 February) for its 12th session. Following lengthy and technically challenging discussions in the Air Pollution Working Group, the Sub-Committee agreed a draft revised Annex VI to the MARPOL Convention and amendments to the NOx Technical Code. These will now be submitted to the Marine Environment Protection Committee (MEPC), which meets for its 57th session from 31 March to 4 April 2008. A number of options remain open for discussion at the MEPC, which is expected to approve the amendments prior to their formal adoption at MEPC 58 (6 to 10 October 2008).
