Statutory Documents - IMO Publications and Documents - Resolutions - Marine Environment Protection Committee - Resolution MEPC.206(62) Procedure for Approving Other Methods of Ballast Water Management in Accordance with Regulation B-3.7 of the BWM Convention (Adopted on 15 July 2011) - Annex Procedure for Approving Other Methods of Ballast Water Management in Accordance with Regulation B-3.7 of the BWM Convention - 5 Application to the Committee for approval in principle of an other method - Equivalence and benchmark criteria for an application for approval in principle of an Other Method

Equivalence and benchmark criteria for an application for approval in principle of an Other Method

  5.3 Applications for Other Methods should contain a fully developed independently validated approach for assessing the level of protection provided by that Other Method against the transfer of harmful aquatic organisms and pathogens and its equivalence to the requirements in regulations B-3.1 to B-3.5 of the BWM Convention and the additional requirements outlined in this Procedure, as appropriate. A possible starting point for such an approach could be a comparison of the level of protection ensured by ballast water management in compliance with regulations B-3.1 to B-3.5 and the level of protection ensured by the Other Method if used on comparable ships.

  5.4 Other Methods should demonstrate by risk assessment, independently validated physical and biological modelling, operational testing of this modelling and full-scale operational testing, where applicable, that the Other Method is capable of meeting at all times a level of protection that is at least equivalent to the level of protection with respect to the prevention of the transfer of harmful aquatic organisms and pathogens via discharge of ballast water compared to existing requirements. The risk assessment should be at least to the same level of rigour as stipulated in Guidelines (G7).

  5.5 Applications for Other Methods should specify the benchmark against which the performance of any systems based on that particular Other Method can be measured. The benchmark would:

  • .1 enable a transparent comparison by the Committee of the level of protection provided by the Other Method with that provided by the requirements in regulations B-3.1 to B-3.5 of the BWM Convention;

  • .2 be measurable and able to be evaluated for approval (similar to the requirements of the Convention, i.e. D-1 being a process evaluation, while D-2 is a measurable performance standard);

  • .3 be verifiable by port and flag States through sampling, records or other processes (to be properly defined, listed and technically explained/clarified, in the pertinent application, in terms of proposed verifications for flag State or port State control inspections to be carried out on board);

  • .4 need to be contained in the application, agreed by the Committee and then be used for consideration of approval through compliance testing by Port State Control;

  • .5 provide an assurance that systems based on an Other Method are providing the same level of protection for the environment as the Other Method that has received the approval in principle from the Committee; and

  • .6 be based on a recognized international standard, where appropriate, so long as they can be proved as equivalent to the existing requirements.

  5.6 An Other Method may provide the same level of protection for the environment, human health, property or resources where:

  • .1 the ballasting and de-ballasting process does not transfer harmful aquatic organisms and pathogens; or

  • .2 the ballast water discharge contains no harmful aquatic organisms and pathogens.
