The Ballast Water Management Convention provides in its regulation D-3.2 that ballast water management systems that 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.
The Marine Environment Protection Committee (MEPC), at its fifty-third session (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 agreed with the establishment of a Technical Group (GESAMP-Ballast Water Working Group) under the auspices of GESAMP* , to evaluate such systems and advise the MEPC accordingly.
MEPC 57 (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). 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.
Following the consideration of the relevant reports of the GESAMP-BWWG, MEPC, at its sixty-eighth session (May 2015), granted five Basic Approvals and one Final Approval 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 Approval from March 2006 until May 2015.
