Tri-Phase was retained to complete the remediation of PCB-impacted soil as well as the decommissioning of an offline transformer at a power utilities site in the GTA.  The site had fallen victim to a copper theft and as a result, oil containing low levels of PCBs had leaked onto the property.

Our scope of work involved draining and disposal of the remaining oil from the transformer, removal and disposal of the transformer, excavation and disposal of contaminated soil (2,500 tonnes).  Tri-Phase also restored the site by backfilling with clean fill material and compacting the impacted areas.

In order to prevent the spread of and cross contamination, a containment area of polyethylene sheets was placed around the transformer during draining and removal.  These containment controls were also implemented during excavation and shipping of the contaminated soil.  These controls required our transport trucks to enter into a sanitary poly-sheeted loading area and ensured that all soil was loaded into the truck for transport and any spillage was captured and returned to the hot zone.

Tri-Phase completed the project on time and within budget.
