The automatic stopping device is a device used, where applicable,
to automatically stop any discharge overboard of oily mixture when
the oil content of the effluent exceeds 15 ppm. The automatic stopping
device should consist of a valve arrangement installed in the effluent
outlet line of the 15 ppm Bilge Separator which automatically diverts
the effluent mixture from being discharged overboard back to the ship's
bilges or bilge tank when the oil content of the effluent exceeds
15 ppm.
