150 Blackburn Boulevard - Excess Soil Management, Sampling & Testing

With the new excess soil rules being implemented in January 1st, 2021 all excess soils generated on a project must be management under Ontario Regulation 406/19 under the Environmental Protection Act – On-site and Excess Soil Management. The City of Vaughan awarded the replacement of the remediation and cleanout of the Blackburn & Franklin stormwater pond .The soils within the stormwater pond to be removed total 7,200 m3, and were to be shipped off site to a suitable beneficial reuse site based on the classification of the soils. AllRock Role AllRock is a company that carries out geotechnical, materials and environmental testing company in Ottawa, Toronto and Newfoundland and Labrador. AllRock was retained to perform Excess Soil Management and Environmental Soil Testing in Toronto for the soil generated during the project. Acting as the Qualified Person (QP) in Toronto, AllRock reviewed the environmental testing data from the previous Geotechnical report to Table 2.1 Excess Soil Quality Standards (ESQS) and the Table 2.1 Leachate Screening Levels (LSL). AllRock also prepared an Assessment of Past uses in Toronto in leu of a Phase I Environmental Site Assessment. AllRock then determined a supplemental subsurface investigation was required to ensure the project met the O. Reg requirements. AllRock prepared a sampling and analysis plan and completed a test pitting investigation in order to obtain samples, to be submitted for analysis of various bulk parameters and leachate analysis. Once the environmental results were received, a soil characterization report in Toronto was prepared. Prior to the supplemental subsurface investigation, AllRock worked in conjunction with the client to develop an excess soil management plan in Toronto, for submission to the City Environmental Professional assigned to the project. Once approved, AllRock ensured the requirements outlined in the management plan were met, including all the typical requirements of soil tracking in Ottawa and Toronto. Once the excess soil was transported and tracked to its final location, AllRock provided a final excess soil management report and provided it to the City Environmental Professional.
