CWC 221: Waste Oil and Mixed Oil Site 2006Quantity Ib 2010quantity (lb) LLNL 34,644 22,124 SLAC 28,207 5,472 LBNL 8,044 91009 Primary waste generators: For LLNL 6.1 Fleet and Machine Maintenance In 2006, approximately 21,826 lbs of waste (63% of the total CWC 221 waste stream) was attributed to Fleet and facility maintenance operations. An additional 12,818 lbs of waste was included in the total CWC 221 volume in the 2007 SB14 Plan, but only the largest waste stream was addressed. In 2010, Fleet Management and Heavy Equipment Shop operations generated roughly an equivalent amount, or 22,124 lbs of this waste stream. This similar generation rate shows that existing source reduction measures are effective because the 2010 generation rate now includes waste from two additional sources besides Fleet. There are now three different locations that generate used oil. The largest generating location collects oil in a 1000 -gallon tank and the two smaller operations collect oil in 55 gallon drums. Collected oil from all three locations is consolidated and sent off-site for recycling. Additionally, LLNL reduced its vehicle fleet by approximately 250 vehicles, thus operated and maintained fewer vehicles during 2010 than it did in 2006, which is expected to lead to even lower waste generation in the future. Current best management practices include better tracking of used oil from the three sources of generation, spill prevention using secondary containment and drip pans, and segregation of vehicle fluids such as hydraulic fluids, engine oils, gasoline, diesel and antifreeze to facilitate recycling. As another pollution prevention effort, the Heavy Equipment Shop implemented use of citrus -based cleaners for degreasing and improved the shop method for preventing oil spills when working on equipment both in the shop and in the field. For SLAC 6 Machining Operations and Electrical. Mechanical and Machinin Equipment Oil Replacement and maintenance This waste stream is generated as a result of replacement of oils used to operate electrical, mechanical (pumps, compressors) and machining equipment. The following source reduction measures have been implemented: • SLAC has been redesigning the equipment, as they fail due to age, to eliminate water intrusion and to provide better heat transfer for critical components. • When feasible, SLAC reconditions oil by removing particulates and moisture and returning it to electrical equipment. • Where appropriate, air-cooling is used to cool dielectric oils and electrical equipment. SLAC has implemented, and will continue to implement, such measures where technically and economically feasible. Oils from mechanical equipment such as pumps and compressors and from machining equipment are usually changed in accordance with equipment requirements and performance. SLAC continues to improve the service life of its electrical equipment; however, results are not measurable at this time since incremental improvements do not result in immediate reduction in waste generation at this time. The variation in the quantity of oil generation in 2010 (5,472 pounds) was significantly less than 2006 (28,207 pounds), due largely to differences in the size and quantity of equipment serviced. It is expected that this waste quantity will vary from year-to-year, but will decrease over the long term as a result of continuous improvements in operations and equipment servicing. For LBNL 6.3 Service and repair of heavy machinery. oumns and other equipment This waste stream is generated throughout LBNL as a result of maintenance of equipment such as heavy machinery, pumps, etc. The generation of this waste stream has been reduced by more than 82% since 1994. The remaining oil generated at LBNL is recycled. Source reduction measures already implemented include closing of the on site motor pool, purchase of oil -less pumps, installation of cyclone dewatering devices on some tanks, and optimization of oil consolidation strategies at waste accumulation areas. Additional oil less pumps have been implemented during last eight years. Routine oil generation has also been reduced. The 2010 rates are slightly elevated over the 2006 rates since numerous transformers were serviced, thus contributing to the oil generation rates. No transformers were emptied in CY 2006.
