INTERNATIONAL CONVENTION FOR THE CONTROL AND MANAGEMENT OF SHIPS' BALLAST WATER

AND SEDIMENTS, 2004

List of ballast water management systems that make use of Active Substances

which received Basic and Final Approvals 1 The Ballast Water Management Convention (BWM Convention) provides in its regulation D-3.2 that ballast water management systems which make use of Active Substances, to comply with the Convention, shall be approved by IMO based on a procedure developed by the Organization. According to regulation A-1.7 of the same Convention, an Active Substance is a substance or organism, including a virus or a fungus that has a general or specific action on or against harmful aquatic organisms and pathogens. 2 The Marine Environment Protection Committee (MEPC), at its fifty-third session (18 to 22 July 2005), adopted the "Procedure for approval of ballast water management systems that make use of Active Substances (G9)" by resolution MEPC.126(53). At the same session, MEPC established a Technical Group (GESAMP-Ballast Water Working Group) under the auspices of GESAMP*, to evaluate Active Substances and the relevant systems and advise the MEPC accordingly. 3 MEPC 57 (31 March to 4 April 2008) adopted resolution MEPC.169(57), which revokes resolution MEPC.126(53) and contains the revised "Procedure for approval of ballast water management systems that make use of Active Substances (G9)". 4 Section 8 of Procedure (G9) sets out the methodology to be followed for the two-tier approval of ballast water management systems that make use of Active Substances and requests IMO to record the Basic and Final Approvals and to circulate the list once a year. 5 Following the consideration of the relevant reports of the GESAMP-BWWG, the MEPC, at its sixtieth session (22 to 26 March 2010) and sixty-first session (27 September to 1 October 2010), granted 11 Basic Approvals and 10 Final Approvals to ballast water management systems that make use of Active Substances. The annexes to this circular contain relevant information on the ballast water management systems that received Basic and Final Approvals from March 2006 until December 2010. 6 This circular supersedes Circular BWM.2/Circ.23.
