6. CWC 223: Unspecified Oil -Containing Waste <br />Site <br />2010 uanti lb <br />2014 quantity lb <br />SLAC <br />34,222 <br />22,686 <br />SNL/CA <br />14,425 <br />10,247 <br />LLNL <br />12,750 <br />0 <br />Far SLAC <br />6.1 Oily Solid and Solvent Solid Debris <br />In 2010, 34,222 pounds of this waste stream were generated and in 2014, 22,686 pounds <br />were generated indicating a trend in the right direction. <br />This waste stream is generated in the forms of: <br />• Replacement of old T20s, air compressors, vacuum pumps and other small <br />electrical equipment <br />Oily rags or wipes to cleanup equipment and machines that are identified above in <br />waste stream CWC 221 <br />• Rags used for cleaning of tools <br />• Absorbents and rags from machines that inherently release oil during metal <br />machining operations or from machines that leak <br />• Miscellaneous oily solids from old containers, cleaning of sumps/secondary <br />containment, roofing and tarring operations, and other similar activities. <br />Ongoing hazardous waste management training and segregation of hazardous and non- <br />hazardous debris resulted in a significant waste reduction in 2014. <br />6.2 Spent Machine Coolant (Cutting Fluid} from Machining Operations <br />Oil from machining operations is usually in the form of soluble oil that is mixed with <br />water and acts as a coolant for parts and tools in machining processes. SLAC will <br />continue to upgrade to machines with more modern internal coolant recycling systems. <br />6.3 Oil—Water Waste from Mair►tenance/Repair of Buildine and <br />Electrical Equipment <br />High voltage electrical equipment is maintained by SLAC Power Conversion Group. <br />Oil -filled equipment are being phased out due to ongoing changes in operational needs <br />as well as experimental needs. More reliable oil free equipment is purchased to reduce <br />the generation of oil -water waste. <br />September 2, 2015 SB 14 Report III -10 <br />
