Challenge
SLR provided Environmental Consulting services following release events of light crude oil along a pipeline in Saskatchewan and Manitoba, Canada. The releases occurred in agricultural and natural land use areas in the Canadian prairies. Impacts were encountered in surface and sub-soils, surrounding vegetation, and surface water bodies.
Solution
The initial response efforts included: shutting in and isolating the failed pipeline; prevention of further surface impacts by advancing containment berms; and recovery of free phase product.
Remediation efforts included: the removal and disposal of impacted water; the excavation of impacted soils/sediments; and removal of visually impacted vegetation.
Where oil impacts were present within a creeks’ sediment and substrate, the creek was diverted around the work area to allow for the mechanical excavation of the areas of concern.
Following the response and remediation efforts; the sites were reclaimed / restored to mimic pre-existing conditions while meeting client, stakeholder and regulatory requirements.
