The surface vessel bilgewater/OWS discharge consists of a mixture of wastewater and leakage from a variety of sources that are allowed to drain to the lowest inner part of the hull, known as the bilge. The anticipated standard will require, where practicable, the collection and transfer of bilgewater for on-shore treatment. Where it is impracticable to collect and transfer bilgewater, the bilgewater must be processed through an oil water separator, and meet effluent limits, which may vary depending upon the type and age of the vessel.
