The Coast Guard announced the availability of its practicability review conducted for the purpose of determining whether technology to comply with a performance standard more stringent than that required by the Coast Guard’s current regulations on ballast water discharges can be practicably implemented and whether testing protocols that can assure accurate measurement of compliance with a more stringent performance standard can be practicably implemented.

In the practicability review, the Coast Guard concludes that, at this time, technology to achieve a significant improvement in ballast water treatment efficacy onboard vessels cannot be practicably implemented.

The reason for this determination is that, as of the date of completion of the practicability review, there are no data demonstrating that ballast water management systems can meet a discharge standard more stringent than the existing performance standards.

In light of this determination, the Coast Guard has not evaluated whether testing protocols exist which can accurately measure efficacy of treatment against a performance standard more stringent than the existing performance standards.
