pump, control panel, two oil-water separators, flow meter, holding tank and various valves. The holding tank has a 75-
gallon capacity. The oil is stored while the vessel is operating in the contiguous zone until It can be dis- charged to a
holding tank ashore.. The level of oil in the tank is determined by checking the sight glass on the front of the tank. After
each use of the oil/water separator system, check the sight glass to see if the tank needs emptying. Over-filling the tank
