hazardous materials.
In October 1998, Woodward-Clyde and CMPS&F undertook an environmental characterisation study of Cockatoo Island for the Department of Defence. As part of this study, a hazardous materials survey of materials associated with buildings, structures and machinery was conducted. The Harbour Trust also conducted further detailed surveys of buildings in order to prepare hazardous materials abatement plans and registers for implementation prior to building refurbishment, demolition or lease. At the commencement of the Harbour Trust's occupation of Cockatoo Island:
  * Small amounts of friable asbestos materials remained on the site. These included asbestos insulation on small furnaces, boilers and pipes, asbestos seals and gaskets, asbestos cored fire doors and globe supports. Most of these materials have now been removed. The majority of the remaining asbestos materials were in the form of asbestos cement products, such as corrugated asbestos cement (AC), and flat AC sheet walls and ceilings. Other minor materials included asbestos backing boards and arc shields in electrical cabinets and AC fragments in some locations. Materials were found to be in generally good to fair condition, and did not provide an unacceptable immediate health risk while they were undisturbed.
  * SMF existed in several buildings in the form of roof insulation batts and insulation around hot water pipes. These materials were generally in good condition, and did not pose a health risk while they were undisturbed.
  * More than 50% of the sample capacitors associated with light fittings contained elevated levels of PCBs, which required management as Scheduled PCB wastes. Any electrical transformers that remained on the island may also have contained PCB contaminated oil.
  * Paint samples collected from building surfaces showed generally all paint systems on the island may be considered to have contained lead, ranging up to 26% w/w, plus other heavy metals. The majority of the lead-based paint systems identified showed signs of deterioration and in many areas, paint systems were blistering and peeling. During any refurbishment of buildings, paint debris should be handled and disposed of according to applicable standards and guidelines. Demolition of buildings does not require removal of paints from surfaces.
  * Samples collected from the interior of buildings reported elevated lead concentrations, which may be attributable to deteriorating paint surfaces. Dust samples collected from the Powerhouse contained elevated concentrations of mercury, which was likely to be due to past spillages. Accessible dusts are to be removed from within the buildings to be retained prior to permitting public access.
  * Other 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
