Activists worried about pollution think the plan to scuttle a former navy vessel should itself be scuttled

20 March 2010 – The former HMAS Adelaide, the navy frigate involved in the rescue of Tony Bullimore in 1997 and the "children overboard" incident in 2001, had a habit of sailing into controversy. Due to be scuttled off Avoca  Beach 
While the state government has declared the ship is free of carcinogenic toxins, its testing for those toxins has been described by an international expert as "shockingly irregular" and "strange". Local protest groups are hoping to scuttle the scuttling for several reasons, including the suspected presence of toxins on the ship and a forecast 5.3 metres of permanent beach erosion at Avoca.

But the mood changed in February when a report was released about the environmental effects of the scuttling. Protest groups are now calling on the federal minister responsible, Peter Garrett, to withhold his department's signature from the final "sea dumping certificate" necessary to authorise the scuttling.
Key to the protest is the possible presence on the 138-metre-long Adelaide of PCBs, or polychlorinated biphenyls, toxic insulator fluids banned in the US  in 1979, a year after the ship was built in Seattle 
PCB exposure in humans has been linked to cancer, liver damage, skin diseases and lowered immune responses. As well as asbestos, CFCs, plastics, high-pressure cylinders and other hazardous materials, the PCBs on Adelaide  were to be removed by the Adelaide  company McMahon Services Australia at Garden  Island 
About 100 to 200 tonnes of material was removed from Adelaide 
The non-specificity of this statement alarmed the No Ship Action Group, which asked the Minister for Lands, Tony Kelly, to guarantee that there were no PCBs left on the ship. He told Parliament on February 24: "I have been advised that all PCBs, lead and other toxic materials have been removed." Subsequently his department commissioned the company Airsafe to test samples from the ship for PCBs on March 1.
The testing found no PCB contamination, but the Herald has been told that Envirolab Services, which did the testing, was unable to sufficiently clean and test some of the samples and was not told where on the ship the samples came from.
The five samples were 10 centimetres by 10 centimetres and were not necessarily from the danger areas of the ship, such as communications, weapons and engine areas. The samples were supplied by McMahon, rather than coming from an independent source.
Colby Self, of the Seattle-based Basel Action Network, which monitors warship clean-ups, says: "I was shocked that there were only five samples taken. It's shockingly irregular compared to the testing done on similar ships in the United States 
Two American warships of the same class, built at the same time as Adelaide , have been tested for PCBs in the US United States Australia 
He says until further remediation and testing are done, there is enough evidence for a delay to the signing of the dumping certificate.
The director of public health at Northern Sydney Central Coast Area Health Service, Dr Peter Lewis, however, wrote in an email to protesters that, when Adelaide 
Dengate, who visited the ship on Wednesday, is satisfied that the ship is "clean as a whistle".
Quentin Riley, from the No Ship Action Group, who was on the same visit, was not convinced. "I couldn't believe that this boat was ready for scuttling. There were sheets of fibreglass matting on the walls that will be ripped out of the ship in the first strong swell. They assured us that there were no PCBs on the vessel but they are working to a tolerance level that is greater than zero. We think that zero is the only safe level for PCBs."
The action group has numerous other objections to the scuttling, including concerns about its effects on surf conditions, the stability of the beach and waterfront housing, the safety of the wreck itself as a dive site, and potential traffic congestion. It also objected to the placement of the ship off Avoca  Beach 
Riley says the coastal engineers Lex Neilson, on whose original report WorleyParsons relied, and Professor Ian Goodwin, of Macquarie   University 
A spokesman for Kelly says there has been extensive community consultation, and the site was named as Terrigal rather than Avoca because boat access to the wreck would be from Terrigal. He says all testing for PCBs had shown the ship is clean.
McMahon Services, which has cleaned up warships for previous scuttlings including the former HMAS Hobart, is barred by its contract with the NSW government from commenting on its work on Adelaide 
Four inspections of the ship have been carried out by the federal environment department's independent expert technical adviser, which cleared the vessel of PCBs, a spokeswoman said.
