XCG was retained to conduct the studies necessary to file a Record of Site Condition (RSC) with the Ontario Ministry of the Environment (MOE) for a commercial property in Kingston, Ontario, to allow for residential land use. The existing commercial building was being renovated for an emergency shelter, low income housing and associated office space. A Record of Site Condition (RSC) was required because of the change to a more sensitive land use.

XCG updated an existing Phase One Environmental Site Assessment (ESA), and completed a Phase Two ESA, to comply with the Ontario Ministry of Environment’s (MOE’s) requirements under Ontario Regulation 153/04 (as amended). This involved full delineation of soil and groundwater impacts across the property. The contamination identified on the site included extensive metals impacts, with lead concentrations in the soil as high as 50,000 to 100,000 µg/g in some areas.

Vapour sampling was completed to collect additional data for use in the risk assessment, related to trichloroethylene (TCE) in groundwater. A risk assessment and risk management plan was prepared and, along with the Phase One and Phase Two ESAs, was used to support the filing of a RSC in accordance with MOE requirements. XCG worked closely with the MOE to expedite the review and approval process of the risk assessment and file the RSC in order to meet project funding deadlines.

XCG was successful in meeting tight timelines for this project: the RSC was filed and the project funding deadlines were met. XCG continues to provide on-going supporting including annual inspection and monitoring services to comply with Certificate of Property Use (CPU) requirements.
