Rock Bay is a former gasworks (MGP) facility that over the course of its operation has contaminated upland areas and also the proximate marine environment. Contaminants of concern include DNAPL, PAHs, PCBs, metals and petroleum hydrocarbons, in soils, groundwater and marine sediments.
The primary purpose of the review is to develop alternative remediation scenarios for consideration by the project team, and a key component of this is Triple-Bottom-Line appraisal of remediation outcomes. Additional duties included review of assessment information, risk assessment and remediation plans prepared by others. WorleyParsons serves to appraise potential implications with cost overruns and/or technical efficacy of proposed remediation. This work is ongoing, and also involves a significant degree of confidential strategic contaminated sites advice that is conducted under attorney/client privilege.
- Reviewed and commented on cost forecasts and the ongoing potential for overruns during the remainder of Stage 2 remediation activities
- Completed a project review, and interviews with key BC Hydro personnel and other project team members to carry forward project learnings
- Reviewed Stage 3 remediation plans, and evaluated BC Hydro’s concept of successful project completion
- Used EcoNomics approach to analyse and present 5 conceptual options based on a revised version of BC Hydro’s Triple Bottom Line planning tool
- Recommended a preferred and secondary option, within a strategy for successful project completion.
Used industry-leading approach (client-specific TBL analysis) to assess one of the highest profile brownfield projects in BC
