Guard is required to publish a ? nal poli- cy letter describing type-approval testing methods, if any, for BWMSs that render nonviable organisms in ballast water.

The BWMSs are to be evaluated by mea- suring the concentration of organisms in ballast water that are capable of repro- duction based on the best available sci- ence in addition to the methods already utilized. In developing a policy letter, the Coast Guard shall take into consid- eration a testing method that uses organ- ism grow-out and most probable number (MPN) statistical analysis to determine the concentration of organisms in ballast water that are capable of reproduction and shall not take into consideration a testing method that relies on a staining method that measures the concentration of organisms greater than or equal to 10 micrometers and organisms less than or equal to 50 micrometers. This provi- sion effectively directs the Coast Guard to adopt the IMO process of using the ‘most probable number’ (MPN) meth- od for determining the effectiveness of
