ABSTRACT:
A system for marking unauthorized discharge of bilge waste, including a supply for containing a dye tracer product within the confines of a vessel, an interface line for adding the dye product via a flow line to the overboard discharge line of a marine vessel, valve controller for valving the flow of dye product between the supply tank and the vessel overboard discharge line, an activator for activating the valve controller responsive to the sensing of a preset level of waste products being discharged via the overboard discharge line so that unauthorized discharge of waste material from the vessel's bilge via the overboard discharge line automatically activates the valve controller to mix a dye product contained within the supply tank with the unauthorized fluid discharge.
