1 Introduction

  1.1 The "Procedure for approval of ballast water management systems that make use of Active Substances (G9)" (Procedure (G9)) provides that, subject to evaluation against the criteria developed by the Organization, an Active Substance or Preparation may be used for Prototype or Type Approval testing for the approval of different ballast water management systems (BWMS).

  1.2 The objective of this document is to provide guidance for the manufacturers and the Administration, and for other interested parties, in preparing an application based on the use of an original Basic Approval and, for its subsequent evaluation by the GESAMP-BWWG for Final Approval according to Procedure (G9).

  1.3 An Active Substance or Preparation should be identical to the Active Substance or Preparation that has already received Basic Approval and its treatment concentration should be less than or equal to the original Basic Approval. In addition, any recommendations by the MEPC for the Basic Approval, including neutralization and maximum allowable discharge concentration (MADC) considerations, should be applied.

  1.4 The document provides a framework including criteria to enable direct comparison of the physical nature of the system, the chemical nature of the Active Substance or Preparation, and the legal and commercially sensitive nature of the information and data being transferred.

  1.5 When considering an application, the use of an Active Substance or Preparation should be substantially similar to the original application that has gained Basic Approval, as this needs to be considered in the context of the BWMS within which it is used. This is because of the way different systems use the Active Substance or Preparation, that may change the nature of the Active Substance or Preparation itself. For example, hydrogen peroxide can be used as a chemical treatment on its own or as a catalyst in combination with a secondary method.

  1.6 Any BWMS that has been granted approval to use a Basic Approval from another system is still subject to the Final Approval process, as set out in Procedure (G9).

  1.7 Any BWMS seeking to use the Basic Approval from another system should also meet conditions or requirements placed on the original Basic Approval by the Committee.

  1.8 Before considering the development of an application to use a Basic Approval from another system, an applicant should consider that the less similarity between the two systems, the more data that will need to be supplied to evaluate the application.
