Orica has not got a great track record. The number of incidents have many Newcastle city residents wanting the company to shift its plant elsewhere. Somewhere away from a populated area....
This is a list of incidents Orica has had in the recent past.
In AustraliaMercury leak, 2011The Botany chemical plant released mercury vapour into the atmosphere on 27 September 2011, breaching environmental standards for nine hours. An air monitor located near residents at Banksmeadow detected the mercury vapour and the Office of Environment and Heritage was notified. Dr Mariann Lloyd Smith, said the length of time the emissions last was extraordinary, "Mercury is extremely toxic. It is recognised as one of the most important and most hazardous toxins that we deal with, and there is currently a UN negotiation for a global treaty on mercury to address this," she said. The mercury vapour was associated with mercury which had polluted the soil on the Orica site, due to leaking pipes. Robyn Parker, the New South Wales Minister for the Environment & Heritage said "I am incredibly angry and disappointed that yet again we have another incident with Orica." In January 2013, the NSW EPA announced that it would conduct a review of off-site emissions of mercury.
Mercury leak, 2012On 17 January 2012 Orica reported a mercury leak at its Port Botany plant, the second mercury incident since August 2011. In a series of samples of environmental air, the EPA recorded a mercury level of 0.0049 grams per cubic metre (8.3×10−6 pounds per cubic yard); more than double the regulatory limit of 0.002 grams per cubic metre (3.4×10−6 pounds per cubic yard).The leak occurred in December 2011 and Orica failed to report the leak to authorities until the following month. The site of the breach was the thermal desorbtion stack at the company's carpark waste remediation project, which was closed when the breach occurred. The NSW Environmental Protection Authority said the incident was not linked to the mercury emissions breach in September at Orica's other Botany site on Beauchamp Road.
Gladstone, QueenslandCyanide leaks, 2012On 8 June 2012 the Queensland Department of Environment launched a legal prosecution against Orica in the Gladstone Magistrates' Court. The company was charged with 279 counts of willfully contravening its approvals in relation to alleged cyanide leaks into Gladstone Harbour. The government claimed that in January and February 2012, Orica discharged effluent water containing heightened levels of cyanide into Gladstone Harbour. "The charges are related to allegations that the company did not inform The Department of the Environment. The charges related to a breach of conditions rather than any environmental harm
per se".
Kooragang Island, New South WalesThroughout August and December 2011 Orica had six major chemicals incidents or leaks in Australia. The first one was a leak of hexavalent chromium from its ammonium nitrate plant near Stockton that affected 70 households; the second one was the release of arsenic into the Hunter River at Newcastle; the third was of mercury vapours from its Botany site; the fourth was a leak of ammonia from its site at Kooragang Island; the fifth was an ammonium nitrate leak of 20,000 litres (4,400 imperial gallons; 5,300 US gallons) at its Kooragang Island plant, only a day after being allowed to reopen; and the sixth incident was a sulphuric acid leak of approximately 3,000–4,000 litres (660–880 imp gal; 790–1,060 US gal) at its Port Kembla site. The fourth leak triggered a public forum and NSW Government investigation into the leaks, and the temporary shut down of the Kooragang Island plant.
Hexavalent chromium leak, 2011Orica's Kooragang Island chemical plant released hexavalent chromium into the atmosphere on 8 August 2011. The known carcinogen was released between 6 and 6:30pm and the spill continued for approximately 20 minutes. An estimated 1 kilogram (2.2 lb) of hexavalent chromium was discharged from the Orica plant, with another 35–60 grams (1.2–2.1 oz) over the suburb of Stockton. Approximately 20 workers at the plant were exposed as well as 70 nearby homes in Stockton. Orica failed to notify government authorities until 16 hours after the incident and residents were not formally notified for three days. Under a Prevention Notice issued on 11 August 2011, the NSW (OEH) closed the ammonia plant at Kooragang Island. The hexavalent chromium leak was the subject of a NSW
Parliament Upper House inquiry, that was concluded in February 2012.
Hunter River arsenic leak, 2011Effluent containing high levels of arsenic leaked into the Hunter River from the Kooragang Island chemical plant on 19 August 2011 at 3pm. Arsenic had not been used on the site since 1993, however during a cleanup of a hexavalent chromium spill on the site the week prior, old deposits of arsenic leaked into a storage pond and drained into the Hunter River. It was estimated the arsenic concentration was 0.067 milligrams per litre, exceeding licence limits. The NSW Premier said "two spills in a fortnight raise reasonable concerns about systemic failures in the way in which this company is operating its facilities." Barry O'Farrell continued, "I've had a gutful of families being distressed, by potential threats to their safety and threats to their local environment.
Ammonia leak, 2011On 9 November 2011 more than 900 kilograms (2,000 lb) of ammonia was initially suspected of venting to the atmosphere from the Kooragang Island plant during a 45-minute period. The venting was due to a relief valve operating to prevent overpressure of a liquid ammonia tank. Engineering studies subsequently revised the amount down to ~90 kilograms (200 lb). The leak was identified by firefighters responding to an alarm raised by the hospitalisation of two railway workers at Mayfield who were affected by the plume of escaping gas. Six fire units and a hazardous chemicals unit were called to the chemical plant to deal with the leak of the ammonia gas. Despite initial statements by Orica that the leak posed no public health risk, two rail workers in the nearby suburb of Mayfield East were overcome by ammonia fumes and were taken to hospital with breathing difficulties. Less than an hour before the ammonia leak, the Environment Protection Authority announced it would take Orica to court over the hexavalent chromium leak which occurred on 8 August 2011 at the same plant.
Ammonium nitrate leak, 2011On 7 December 2011, in excess of 20,000 litres (4,400 imp gal; 5,300 US gal) of weak ammonium nitrate (<35%) solution/fertilizer leaked onto grassed areas at the Kooragang Island chemical plant. Emergency services were called to the site including a HAZMAT team. The spill occurred less than a day after the Environmental Protection Agency announced it would allow the reopening of part of the Kooragang Island plant. Local residents continued to criticise the company for failing to notify residents in a timely manner and called for the plant to remain closed.
Hydrogen stack fire, 2012On 8 January 2012 lightning ignited hydrogen being released from the plant. Flames higher than 20 metres (66 ft) leapt from the hydrogen stack and were reported by local residents to authorities.
Port Kembla, New South WalesSulphuric acid leak, 2011A spill of approximately 3,000–4,000 litres (660–880 imperial gallons; 790–1,060 US gallons) of concentrated sulphuric acid occurred at the Port Kembla chemical plant on 16 December 2011. The leak was suspected to be caused by a hole in the ship-to-shore pipeline. Acting chief environmental regulator Mark Gifford from the NSW EPA said he was concerned about the ongoing incidents with Orica.
