U.S. EPA science advisory board issues its draft efficacy of ballast water treatment Systems report
Five categories of treatment systems The U.S. Environmental Protection Agency (EPA) Science Advisory Board issued its draft Efficacy of Ballast Water Treatment Systems Report on 31 May.The report in its final form could form the foundation of Federal and State legislation on ballast water treatment and as such has some important conclusions regarding the ability of ballast water treatment systems to be able to meet more stringent requirements than those in the IMO's Ballast Water Convention.The significant outcome of the report suggests that there are five categories of treatment systems** currently available to the shipping industry that can meet the IMO standard (Phase 1 of the proposed U.S. Federal rules). However, to meet standards 100x or 1000x more stringent would require a whole new process of treatment and measurement of effectiveness as opposed to improvements on the current systems.Noting current limitations on the ballast water treatment and testing protocols, the Report recommends: a risk-based systems approach to setting goals and implementing ballast water management; the use of improved sampling protocols for verifying discharge concentrations; the development of reliable protocols for compliance monitoring; and even the consideration of reception facilities to treat ballast water discharges - it seems the use of ...
