Update on HMAS Platypus
Planning is now underway for the remediation of the former HMAS Platypus site. This is the first step in transforming the former submarine base into a new public waterfront location.
Over the years this complex site in Neutral Bay has been transformed and its sandstone cliffs excavated: firstly for a gasworks, then a workshop for servicing torpedoes, and finally a base for Australia's submarines.
A Memorandum of Understanding (MoU) between the Department of Defence and the Harbour Trust has now been signed. Defence has agreed to pay for the costs associated with the decontamination of the Platypus site.
The current plan is to carry out the remediation project in two stages:
Stage 1 encompasses the above ground remediation and site preparatory works. During this stage, the wharf and seawall will be repaired, sediments in the adjacent waterways investigated to provide background reference information, dilapidation surveys undertaken, above ground contaminants including lead and asbestos will be removed from all buildings and surrounds, the heritage significant retort building dismantled and the administration building and adjacent store demolished. Stage 1 is planned for completion in late 2010.
Stage 2 addresses the below ground contaminant removal and groundwater management works. During this stage, the estimated 35,000 tonnes of below ground hazardous contaminants will be removed and treated, the contaminated ground and seepage water will be treated and a plan for future groundwater management put in place. Planning for this stage is now underway. Stage 2 is planned for completion in late 2012.
This is a complicated project requiring on-going community consultation and detailed planning prior to the works proceeding. The Harbour Trust has recently appointed a Community Consultation Manager and additional Project Management personnel to assist in the co-ordination and implementation of the works.
