November -16-20,2020 MEPC 75 took place, hosted remotely by IMO in London.
MEPC noted, discussed and concluded that the Total RESIDUAL Oxidizers (TRO) should be the parameter to be used for the testing of the quality of discharge Ballast Water. MEPC did not accept to replace TRO measurements by Oxidation-Reduction Potential measurements.  TRO measurements can be carried out on board vessels also using available specialized testing kits. MEPC 75 will circulate their new revisions on Ballast Water Management as BMW.2/Grc.70/Rev.1.
