All of the routinely generated hazardous waste streams at AIT during the <br />1998 reporting year are contained in Table1., major waste streams are <br />identified by an X in the right-hand column. <br />Generated <br />Percent by <br />Percent by <br />Hazardous <br />CWC• <br />Weight in <br />Weight <br />Weight <br />Major Hazardous <br />Waste <br />Pounds lbs. <br />Nona ueous <br />(Aqueous) <br />Waste Stream >5% <br />Spent Lead Filters <br />352 <br />4,740 <br />31% <br />X <br />Lead Sludge <br />491 <br />4,050 <br />27% <br />X <br />Spent DI Sys.

AIT HAZARDOUS WASTE STREAMS <br />5.2. Figure 3. (next page) contains a block flow diagram outlining the <br />processes, operations, and activities generating the major waste streams <br />for the reporting year of 1998. <br />5.2.1. Stamping Process - The stamping process generated 900 lbs. of <br />Mixed Solvents hazardous waste during 1998. <br />5.2.1.1. Mixed Solvents - A majority of the waste is generated from <br />replacing used lubricating oil which becomes contaminated <br />with dirt and metal particles during the stamping process. <br />Some amount of acetone and isopropyl alcohol (IPA), <br />(used for cleaning surfaces, contamination testing, and <br />cleaning measuring equipment), is also included in this <br />waste stream. <br />5.2.2. Degreasing Process — The degreasing process generated 2,300 <br />lbs. of Used Ensolv (Dibromopropane) hazardous waste during <br />1998. <br />
