Clean ballast
"Clean ballast" means ballast in a tank that has been washed out after the last voyage with oil cargo such that discharge from such a tank from a stationary ship into clean, calm water on a clear day does not result in visible traces of oil on the surface of the water or on the adjacent shore and does not cause sediment or emulsion under the surface of the water or on the adjacent shore. If ballast is discharged through an approved administration system for measuring and controlling oil discharge, readings from such a system indicating that the oil content in the discharged effluent does not exceed 15 parts per million are accepted as evidence of clean ballast, regardless of the presence of visible traces.
