miscellaneous hazardous materials include small volume chemicals, oily and aqueous liquid wastes in tanks and pits, electrical wastes (batteries, transformers and switch boards), metal swarf and general rubbish.
It is the Harbour Trust's policy to undertake hazardous materials survey, removal and abatement programs prior to building refurbishment or demolition. As discussed later in this Plan, this has been completed for many of the buildings across Cockatoo Island. Any remaining hazardous materials in these areas, such as AC sheeting in good condition, will be managed in accordance with hazardous materials register and management plan prepared for the site.

Remediation & Decontamination Works Undertaken to Date
Most of the machinery, equipment and waste, and many of the buildings, associated with the Cockatoo Island Dockyard operation were removed following the 1992 decommissioning of the island – see Appendix 1. However some significant machinery remains. Most significant of these are the 38 cranes (11 external) from various periods of the island's development.
In 1999/2000 Thiess Environmental Services carried out the following works for the Department of Defence, under the direction of the CIRC:
  * Decontamination of Building 117 in ground pit associated with the electroplating facility;
  * Demolition of Buildings 89, 117, 121 and the Camber Wharf muster station;
  * Removal and disposal of eight known underground storage tanks;
  * Demolition of Wharf crane C301;
  * Demolition and removal of the Old Plate Wharf, Cruiser Wharf, Destroyer Wharf, Ruby Wharf and steps and the Camber Wharf. Timber from this activity was piled in the Turbine Hall (Building 150); and
  * Sea wall reconstruction in selected areas.
Concrete material stockpiles on the northern apron were recycled from clean building demolition materials generated during this period.
Between 2002 and 2008, the Harbour Trust carried out rehabilitation of the Eastern Apron and entry plaza areas, Plateau, Northern Apron and Southern Apron. This work involved:
  * Gross decontamination of buildings;
  * Survey, removal or abatement of hazardous materials to allow for building conservation and repairs;
  * Removal and disposal of visible asbestos fragments and other gross wastes across all surfaces;
  * Management of excavated clean and contaminated materials;
  * Installation of new concrete and bitumen hardstand in localised areas;
  * Placement of clean separation layers over modified unsealed areas. This has generally comprised of a geofabric marker under clean crushed concrete, topsoil and turf;
  * Recycling and removal of wastes from around the island; and
  * Decommissioning/reinstatement of the stormwater/sewer network, and service trenching/laying out of new services.
It is the Harbour Trust's policy to undertake hazardous materials surveys, removal and abatement programs prior to building refurbishment or demolition. Since 2005, above ground and subsurface hazardous materials and contamination has been progressively removed from Cockatoo Island, or contained
