March 5 - March 18, 2005:  
-1 OSC, 2 PST, 3 START, 16 ERRS;
ERRS segregated and containerized radium containing materials (RCM) and surface contaminated objects (SCO) from the west warehouse at 10800 Burbank Blvd.  ERRS removed hazardous substances from gauges.  Hazardous substances included chlorinated and non-chlorinated solvents and mercury.  Approximately 80-120 cubic yards of SCO were shipped off-site daily.  On March 11, 2005 and April 1, 2005, the remaining RCM was shipped off-site for disposal.

ERRS demolished the offices in both sides of the structure.  Demolition debris was disposed of as SCO.
