The TPS was contracted to treat a volume of PCB contaminated soil stored in skips at an EPA Schedule 4 Store located in Moe, Victoria. Elevated PCB (Arcolor 1260) concentrations were detected for samples collected from the skips. The highest concentration detected was 1,300 mg/kg. The average PCBs concentration for the skips was 361.5 mg/kg. The analytical results for skip soil samples did not indicate any significant contamination form any other chemicals.

During 2000, the TPS conducted the Stage 1 treatment of the PCB contaminated soil. An independent consultant was to confirm acceptable treatment levels were achieved in the project. The consultant collected one sample of the treated soil on an hourly basis from the exit hopper. Samples were composited at the laboratory into groups of six analysis. This represented approximately one composite per skip. Waste water, sludge, oversize rubble and process gas were also sampled.

Analytical results pertaining to the TPS indicated the following:

•	Average treated PCB concentration was 0.9 mg/kg.
•	Following the treatment of the soil through the TPS unit, the concentrated sludge contained PCBs of approximately 17,000 mg/kg, which was expected.
•	During the TPS operations, the process gas was filtered prior to venting to atmosphere. This process gas was monitored regularly to ensure compliance with the license condition of < 1 mg/m3 at the second last filter. All 18 samples indicated no detectable PCBs with a PQL of < 0.01 mg/m3 at the second last filter.
