Reclaimit’s environmental consultancy team was engaged for the environmental assessment, remediation planning, and remedial project execution for a historic oil and gas liquid waste disposal facility. The feature was located in the boreal forest region of western Canada and included above ground waste storage infrastructure and a downhole injection well for disposal of approved liquid waste substances.
The project scope of work required an environmental consultant-lead site assessment to determine the type and extent of environmental contamination associated with the development. The environmental site investigation achieved regulatory standards, delineated the extent of contamination, and supported the development of a scope of work for the site’s remediation.
To successfully execute the completion of decommissioning and remediation tasks, Reclaimit consultants directed the removal of surface debris and below-ground infrastructure, provided health and safety oversight for specialized contract services such as pipeline abandonment, and oversaw the excavation, loading, hauling and disposal of all industrial debris and contaminated soil to a regulatory approved disposal facilities. A total of 211 tractor trailer loads (6699 tonnes) of contaminated soil and 3 loads of metal and other industrial remnants were safely disposed. Upon completion of the project the site was rendered ready for its next treatment phase, final surface reclamation.
Read on to gather more detail on the Reclaimit environmental consultancy’s approach to the successful execution of this project scope.
Step #1: Identify Environmental Issues
A previously completed Phase I Environmental Site Assessment (ESA) was provided to Reclaimit’s lead environmental consultant. The consultant reviewed the Phase I ESA, updated it with additional historic management findings and completed a site visit to confirm the site’s condition. A Phase II ESA was then planned to define the type and extent of environmental contaminants on site.
Step #3: Defining the Problem with a Phase II Environmental Site Assessment (ESA)
The Phase II ESA was a strategically focused site investigation, investigating any noted Area of Potential Environmental Concern (APEC) and retrieving samples for analysis for onsite Substance Of Potential Concern (SOPC). Findings were rapidly reported to the client and, as required and in consultation with the client, to government representatives.
Step #4: Clean up the site
Once Phase II ESA results were reported and authorization to proceed with site remediation was received from the client, Reclaimit commenced project tasks including:
- Remove above and below ground infrastructure.
- Excavate, load and haul contaminated soil material and industrial debris, including miscellaneous pipes, metal debris, 3 underground storage tanks, concrete blocks and pieces and other loose cables and garbage to approved disposal facilities.
Contaminated Material Removal & Disposal
Upon safe completion of surface debris and infrastructure removal, Reclaimit initiated the excavation, loading, hauling and disposal of contaminated material to a pre-approved disposal facility. In this case of this project the destination was an approved Class II Landfill. Once material removal was complete confirmatory soil sampling of the floor and sidewalls of excavations took place to confirm all source waste material was successfully removed for disposal.
After contaminated soil material was removed and all regulatory criteria were achieved the environmental consultant deemed the location to be reclamation ready.
