WASTE OIL GENERATION FLOW DIAGRAM <br />Hazardous Waste and Process Description <br />This waste stream is generated from oils used to operate electrical, mechanical (pumps, <br />compressors) and machining equipment. Oil is an important component in the successful <br />operation of electrical and mechanical equipment, and in machining operations <br />performed at SLAC. <br />Oil is also used as a dielectric fluid in high-voltage equipment such as transformers, <br />modulators, power supplies and klystrons. High-voltage electrical equipment is essential <br />to the operation of the experimental research performed by SLAC. SLAC always strives, <br />when feasible, to increase the operating life of ails used in this equipment as a way of <br />reducing maintenance costs. <br />Hazardous Waste Management Approaches <br />The following source reduction measures have been implemented: <br />• SLAC has been redesigning equipment, as it fails due to age, to eliminate water <br />intrusion and to provide better heat transfer for critical components. <br />• When feasible, SLAC reconditions oil by removing particulates and moisture and <br />returning it to electrical equipment. <br />• Where appropriate, air cooling is used to cool dielectric oils and electrical <br />equipment. <br />SLAC has implemented, and will continue to implement, these and other such measures <br />where technically and economically feasible. <br />Oils from mechanical equipment such as pumps and compressors and from machining <br />equipment are usually changed in accordance with equipment requirements and <br />performance periods. <br />September I, 2011 SB 14 Plan <br />38 <br />No new source reduction measures are being considered at this time. <br />Replacing equipment before the end of its useful life is usually not an economically <br />feasible measure for reducing this waste stream. <br />September 1, 2011 SB14 Plan <br />39 <br />
