Environmental Risk Assessment

As part of a municipal plan to redevelop former industrial lands into a recreational community green space, Pinchin was retained by the local conservation authority to provide a risk based approach to managing the contaminants present at the Site. The Site is part of a detailed concept for open public space. The Plan will create one of Canada’s largest urban parks. The project includes sidewalk improvements, tree planting, landscaped parking spaces, and dedicated walking/hiking trails.

In order to complete the redevelopment process, a Record of Site Condition (RSC) from the Ministry of the Environment and Climate Change was required in order to convert the property to a Recreational Land Use. Starting in 2011, Pinchin completed a Phase One and Phase Two Environmental Site Assessment to determine the extent and nature of the contamination onsite. Contaminants of Concern (CoCs) identified included inorganics, polycyclic aromatic hydrocarbons and petroleum hydrocarbons in soil and groundwater.

Pinchin completed a Tier III Risk Assessment. The Risk Assessment process is designed to examine potential risks to human and ecological receptors and propose risk management measures where total remediation of the site is not technically or economically feasible. The results of Pinchin’s RA identified that all CoCs could be managed on Site through a soil cap which would be included as part of the redevelopment landscape.

The Tier III Risk Assessment was a finalist in the Canadian Urban Institute’s Brownfield Redevelopment (Brownie) Awards program. The Brownie Awards recognize leadership, innovation and environmental sustainability in brownfields redevelopment across Canada.
