Metal <br />parts are cleaned through a multi step process including the following: Ultrasonic <br />degreasing; washing with commercial industrial cleaners (such as 909,); Surface cleaning <br />with alkaline solutions, and DI -water and tap water rinsing. The waste stream consists of <br />spent solutions that must be changed periodically to maintain effectiveness. This waste <br />stream is currently collected and shipped to offsite treatment and disposal. Sometimes <br />this waste stream is more caustic and is then coded CWC 121. In 2010 the process <br />generated a waste stream that was less caustic and therefore coded as CWC 135. <br />SOURCE REDUCTION/POLLUTION PREVENTION EVALUATION <br />Description ofMeasure: <br />No new source reduction measures are being considered at this time. <br />3.3 Buildine 963 Sumn Wastewater <br />Site2010 uantit Ib <br />SNUCA 16,033 <br />Raw Materials: <br />Din, Oil, Grease, and <br />City Water <br />powerwashittg <br />CWC 135 <br />ofequipment <br />Unspecified <br />Off-site <br />aqueous <br />disposal <br />solutions <br />FIGURE 111.3.3. FLOW DIAGRAM <br />FOR BUILDING 963 SUMP WASTEWATER <br />The Maintenance Engineering Department power -washes various types of equipment at <br />the B963 wash down pad as pail of routine maintenance. The types of equipment that are <br />power -washed include landscaping equipment, heavy equipment and the trash truck. <br />This activity generates wastewater that is contaminated with oil, dirt and grease. <br />Currently this waste is collected in the oil and water separator located at the B963 wash <br />down pad and disposed of as a non-RCRA hazardous waste, The waste is normally <br />pumped out once a year. <br />SOURCE REDUCTION/POLLUTION PREVENTION EVALUATION <br />Description of Measure: <br />None identified. Workers try to minimize the frequency of power washing equipment <br />and minimize the volume of water used. These actions over time will reduce the <br />volume of waste generated. <br />September 1, 2011 SB 14 Plan 22 September 1, 2011 SB 14 Plan <br />
