Highlight: Instrumental in our client obtaining their redevelopment Site Plan Approval and securing financing from a major lender on a contaminated property for other site upgrades.

After over five years of trying to obtain Site Plan Approval, XCG was retained and was instrumental in clearing all of the environmental conditions imposed by the Municipality and our client was able to proceed with the redevelopment of their property with a new anchor tenant store.  In order to satisfy the Municipality, XCG conducted a Phase I Environmental Site Assessment (ESA), a Phase II ESA, a Supplemental Phase II ESA to delineate impacts, and remediation to meet the soil and groundwater standards for commercial/industrial land use in a non-potable groundwater condition published by the Ministry of the Environment and Climate Change (MOECC) April 15, 2011.  Due to the occupancy of an on-site building, remediation was completed in two phases pending the vacancy and subsequent demolition of the building.  The initial phase consisted of in-situ injection of a chemical oxidant to remediate petroleum hydrocarbon impacts in soil and groundwater in areas where excavation was not feasible.  Prior to demolition of the building XCG had to submit to the Municipality for their approval, a detailed scope of work outlining how the impacts below the building were going to be assessed, and options for remediation. Following the vacancy and demolition of the building, excavation was conducted below the building to remove residual petroleum hydrocarbon impacts associated with a former gas station and oil-water separator.

With our years of experience, and through excellent communication with all parties and detailed project management, XCG was successful in addressing the environmental concerns in the area of the redevelopment to the satisfaction of the Municipality, the client, and in accordance with Ontario Regulation (O. Reg.) 153/04, as amended, and the client was able to proceed with their long anticipated redevelopment.

Following completion of the redevelopment environmental activities, XCG addressed a suspected heating oil underground storage tank (UST) and residual heating oil impacts below an approximately 150 metre span of the main site building, in order to assist our client in obtaining financing to complete major upgrades to the on-site building and property elements. During the excavation to remove the suspected UST, it was discovered the UST had previously been removed; however, the contaminated soil and groundwater had not been removed. XCG provided oversight of the excavation, and conducted confirmatory soil sampling from the excavation sidewalls and floor.  The contaminated soils were removed and disposed of off-site; however, impacted groundwater remained.  During backfilling activities XCG conducted in-situ groundwater remediation by discharging a chemical oxidant into the open excavation.  A few months after the UST excavation, XCG conducted a Phase II ESA to delineate heating oil impacts that had migrated below the main building on the property, and to assess groundwater in the vicinity of the former UST.  Groundwater in the UST excavation and in the vicinity of the excavation exhibited no signs of petroleum hydrocarbon impacts.

Additionally, to aid our client in obtaining traditional financing, XCG conducted a Screening Level Risk Assessment (SLRA) and was able to derive less conservative clean-up standards for the property using the MOECC models.  Using the revised clean-up standards for the site, XCG determined remediation costs for site-specific scenarios that were used by the lender in their risk determination.  Through the efforts of XCG, our client was successful in obtaining traditional financing through a major lender, and was able to complete significant upgrades to the property and building, such as re-paving the parking areas, upgrading major electrical components, and installing new sections of roofing.
