Overall Hazardous Waste and Process Description <br />In 2014, 8,562 pounds of CWC 181 waste generated at SLAC. A breakdown by waste <br />descriptions used in the SLAC hazardous waste tracking system is provided in the table <br />below. <br />o RCRA contaminated debris, debris with non-Kc:ttA mera' <br />10j" <br />Waste Aescription <br />uanti Ib <br />Inorganic Solid Waste* <br />41503 <br />Filter Cake <br />4,059 <br />Total <br />81562 <br />s, <br />spent resins with copper, acid/alkaline debris <br />Ofthe 8,562 pounds of CWC 181 waste generated in 2014 included RCRA Contaminated <br />Debris, Filter Cake, Debris with Ston-RCRA Metals, Spent Resins with Copper, and <br />4W/Alkaline Debris. <br />The processes generating these wastes are: <br />o Repair/upgrade and removal of experimental equipment and lead shielding generating <br />lead and lead debris <br />o Metal finishing operations (discussed earlier) generating filter cake from rinse water <br />and aqueous waste treatment processes <br />Cleanup and maintenance activities that generate debris with non-RCRA metals <br />o Closed-loop, low -conductivity cooling water system generating spent deionization <br />resins with copper <br />o Use of chemicals metal finishing operations that generate empty chemical containers, <br />acid and alkaline debri <br />s. <br />Each of the processes and wastes are further discussed below. <br />Inorganic Sulid Wastc <br />September 1, 2015 SB1 <br />
