Remediation Liability Advice

Senversa was engaged by the (then) Department of Planning and Environment to provide an independent expert opinion to support the Department’s assessment of compliance with conditions of approval and financial assurance provisions for the remediation of the former Pasminco Cockle Creek smelter and Incitec fertiliser plant. Previous lead and zinc smelting at the site during its 100-years of operation resulted in significant contamination of the site and surrounds. Site remediation occurred via removal of contaminated fill and soils, and the shallow aquifer, and emplacement in a fit-for-purpose engineered containment cell. Senversa reviewed site assessment and remediation documentation and provided an opinion to the Department of contamination liabilities and costs associated with perpetual care of the containment cell.
