Abstract : Apparatus for confining a leakage of polychlorinated biphenyl (PCB) from an outdoor electrical substation while permitting rain water to be discharged into the outside environment when no PCB is present. The electrical equipment is disposed on a walled pad having sufficient containment volume to hold the maximum PCB leakage. The outlet from the containment volume is through a water/PCB separator float valve which is disposed vertically in a catch basin. The valve has a tubular body having a flow-through section with apertures which communicate with the catch basin and a converging section of circular cross-section above the flow-through section. A spherical float having a specific gravity between that of water and PCB is confined in the tubular body. The float, while sinking to the bottom of the valve in water, will rise on PCB such that as the level of PCB increases in the catch basin, buoyant forces will cause the float to be seated in the converging section to close the valve and confine the PCB to the containment volume.
