IMO CALLS FOR MORE SCIENTIFIC DATA ON SCRUBBER WASHWATER

Tuesday, February 26, 2019 

The International Maritime Organisation has called on member states to provide scientific research and studies relating to the discharge of washwater from marine exhaust gas cleaning system.

Following the 6th meeting of the Sub-Committee on Pollution Prevention and Response (PPR 6), the Committee heard from Member States who had carried out studies and preliminary studies related to washwater discharge (under the current washwater discharge standards set out in the 2015 guidelines) and the impact on the marine environment.  However, it encouraged interested Member States and international organizations to undertake further scientific research and to submit results to future sessions to facilitate the work on the revision of the 2015 EGCS Guidelines.

The Sub-Committee is undertaking a review of the 2015 Guidelines on Exhaust Gas Cleaning Systems (EGCS) and noted the progress made by the Correspondence Group on review of the 2015 EGCS Guidelines. It agreed to request an extension of the target completion year to 2020 with a view to continuing the work on the review at PPR 7.

In the meantime, the Sub-Committee agreed to forward a new draft Appendix 6 to the EGCS guidelines, developed by the correspondence group, to MEPC 74 (13-17 May) for review and finalization, with a view to potentially issuing it as an MEPC circular. The proposed draft Appendix 6 provides Guidance on temporary indication of ongoing compliance in the case of the failure of a single monitoring instrument, and recommended actions to take if the EGCS fails to meet the requirements of the Guidelines. It aims to address situations in which there is a malfunction of the EGCS system.

The Sub-Committee also requested the IMO Secretariat to explore the possibility of GESAMP carrying out a review of the relevant scientific literature and also overseeing a modelling study of the impacts of discharge washwater from exhaust gas cleaning systems.
