Issues • Imported stockpiles of approximately 100,000 m3 containing bonded asbestos containing material (ACM) and friable asbestos. • Extensive aesthetic impacts across the Site (bricks, concrete, construction waste) • Extensive dispersed bonded ACM impacts to surface soils across the Site • Hydrocarbon impacted soils and groundwater • Potential risks to human health and the environment identified • Site under Section 53x Audit, with strong external pressure on the Client to close out all issues in a timely manner. Strategy • Employed a staged approach to Site investigation to avoid unnecessary works: • Stockpile investigation (grid based) • Site walkovers to document extent of aesthetic impacts and ACM occurrences • Soil investigation to determine extent of previously identified hydrocarbon impacted soils • Groundwater investigation to determine extent of hydrocarbon impacted groundwater • Subsequent remediation works to target affected soils and ensure no unacceptable risk to future site occupants: • Edge developed a comprehensive Soil Asbestos Management Plan (SAMP) • Asbestos impacted stockpiles remediated using screening plant for non-friable asbestos and bulking out methods for friable asbestos (involving high level consultation with Work Safe Victoria’s Lead Hygienist and the EPA appointed Auditor) • Aesthetic impacts removed from across the Site using a combination of hand picking and heavy plant. • Hydrocarbon impacts to soil delineated and excavated for off-Site disposal following characterisation in accordance with EPA IWRG621. Outcomes • Edge provided quality Environmental Assessment Reports to the Auditor to achieve staged clearance of the Audit Areas to allow the Site owners occupancy in a staged manner. • Edge ensured that all works were conducted in accordance with relevant HSE legislation and no notifiable incidents were recorded.
