from the WRS dewatering filter press is tested for TCLP metals, TCLP organics, and free liquids. This waste stream is drummed and shipped offsite for treatment and/or disposal in an appropriate TSDF.
The brine reduction system treats the clarified effluent from the WRS to produce a solid cake that can be disposed of offsite. The filter cake is tested for TCLP metals and organics and for free liquids (PMACWA, 2006).4 This waste stream is drummed and shipped offsite for treatment and/or disposal in an appropriate TSDF.

Laboratory Wastes
Laboratory wastes are collected in each hood. All agent-contaminated wastes are placed in a bleach solution daily. The liquids are decanted, analyzed to confirm that agent has been destroyed, and shipped offsite for disposal (PMACWA, 2006).5 The solids are bagged, screened for agent by head-space monitoring, and drummed for offsite disposal. Process knowledge is utilized to segregate agent-contaminated waste streams from noncontaminated laboratory waste streams; the latter do not require sampling or monitoring.
Finding 4-2. At PCAPP, brine from the water recycling and sludge from the biotreatment are the largest waste streams. They are not considered to be contaminated with chemical agent but may be a hazardous waste for other reasons.
