LULTRA HIGH VACUUM CLEANING FACILITY WASTE GENERATION PROCESS <br />This waste stream is generated as a result of metal surface cleaning operations. Metal <br />parts are cleaned through a multi step process including the following: <br />• Ultrasonic aqueous degreasing, <br />• Washing with commercial industrial cleaners (such as 909, B.N., Blue Gold), <br />• Surface cleaning with acidic solutions, and <br />• DI -water and tap water rinsing. <br />The waste stream consists of acidic wastes that contain particles and dissolved metals. <br />September 1, 2011 SB 14 Plan 62 September 1, 2011 SB 14 Plan 63 <br />
