Featured Project
Middle Harbour Sediment Remediation
Location
Victoria, BC
Key Services
- Dredging and Dewatering
Description
A bustling harbour in Victoria, BC, was the site of a dredging project. Decades of historical industrial use of the area had contaminated the ocean floor, and the objective of this project was to dredge and dispose of PCB-contaminated sediments.
Key Challenges
- Effectively managing classification and segregation of contaminants
- Navigating operational and regulatory complexities of transporting and disposing of PCB-contaminated sediment
Key Solutions
- Utilizing precision dredging with coordinate management to accurately remove sediments from a superficial depth on the ocean floor.
- Milestone meticulously managed the operational and regulatory logistics involved in transporting and disposing of the PCB-contaminated sediment within a bustling harbour used for shipping and float plane operations, necessitating tugboats, rail cars, and barges.
Project Scope
- Mobilization of labour, equipment and materials to safely execute the project.
- Dredging of ~3,200 tonnes of PCB-contaminated soils.
- Water, road and rail transport of PCBs under Transportation of Dangerous Goods (TDG).
- Repackaging of PCBs into UN‐rated containment for transport to thermal destruction.
- Placement of 2,400 tonnes of Residual Management Cover (RMC).
