(v) Edward John Cullen, a Manufacturing Engineering Manager, who was about 80 metres from the wash down bay.
14 Mr Tran described the initial odour as not very strong and like "a chemical or plastic burning". The odour made him feel sick in the stomach and made it hard to breathe but later, when he was in the fresh air, he felt better.
15 Following conversations with fellow workers, Neville Baldwin, a Leading Hand and a Union Delegate, walked towards the wash down bay and detected an odour. He said the odour was "a really strong acrid smell…[it] was hard to describe, it was just a putrid smell". It "gave me an ill feeling, like when you smell something rotten you feel like chucking up". He saw the tanker truck outside but did not speak to Mr Struthers.
16 Paul Madsen, a Production Manager, was working in the warehouse towards the north corner of the building. He detected an odour that he referred to as "a stench". He had a conversation with Mr Struthers who told him that the pumping would take another five minutes. When Mr Madsen walked back into the factory, he found that the odour was twice as bad as it was outside. He could see that most of the workers in the factory had walked out. He went to a couple of them and said "come on its not that bad". However, they told him they disagreed with him. The smell did not affect him as much as he believed it affected the employees on the factory floor.
17 Mr Cullen, who is also the Occupational Health and Safety Officer for Air International, was in the proto-type area some 80 metres from the wash down bay. He noticed a pungent odour, similar to the breaking down of foodstuffs and fermentation. He saw workers from the factory floor had stopped working and were in the process of leaving the factory. Mr Cullen described the odour as "a bit like a rotten food waste smell". He had worked in the food industry and had spent approximately eight months as Project Manager at Frito Lay, in charge of overhauling its liquid waste system. The odour from the tanker truck reminded him of the smell from the wastewater system at Frito Lay in the sense of it being a smell from a food waste. However, he had not smelt that particular smell before or since.
18 Mr Prasad initially detected a faint odour in the factory. He described it as a "rotten type of smell". He continued to work but then left the factory when the other workers were evacuated. At first he went outside the sheet metal area but the odour was bad there so he went to the service bay at the opposite side of the factory. When he got to the service bay he could not smell the odour anymore. He said the odour made him feel bad and it was hard to breathe.
19 Mr Sparkes' work place was about 50 feet from the wash down bay. He describes the odour as "terrible" and "just like rotten egg gas but it was worse than that". It made his stomach "a little bit upset" and "churning".
20 After Mr Baldwin became concerned for the safety of the workers, he caused the whole factory to be evacuated. Between 80 and 100 people were evacuated.
21 Mr Struthers collected approximately three tonnes of liquid waste from Air International. Whilst pumping, Mr Struthers detected an odour from the tanker truck, which he described as "slight" and that there was "a little bit" of a smell. He checked the exhaust system of the vacuum pump and detected that it was "a little bit fumy, but not excessively to what I have smelled before". He could not smell anything extremely offensive. The smell did not seem to indicate, to his knowledge, the presence of toxic fumes. He said "It didn't seem to me as a toxic content. If it was really strong, I would have noticed it". He was not affected by the odour.
22 Although employees at the Huntingwood premises left the factory building because of the odour, no one became ill or vomited. As Mr Struthers was leaving the Huntingwood premises he saw the workers outside the factory and that some of them were eating food. At the time it occurred no one from Air International notified the EPA or emergency services about the odour incident. No one from Air International advised Mr Hill on 15 February 2002, or subsequently, that there had been an odour incident involving Mr Struthers and the tanker truck at the Huntingwood premises.
23 At approximately 9:20am Mr Struthers called Mr Hill on the telephone. Mr Hill directed Mr Struthers to go to the Seven Hills premises and collect some wastewater from a construction site. Neither Mr Struthers nor Mr Hill can recall whether or not the odour event at the Huntingwood premises was discussed during that telephone conversation. Mr Struthers then drove to the Seven Hills premises.
24 The Seven Hills premises are located between the Prospect Highway and a side street. There is a two-storey office building next to the premises and the side street is located between the office building and the premises. Office workers occupy the office building.
25 The Seven Hills premises are a disused petrol station. The site is approximately 1,000m2 to 1,100m2 in size. The old petrol station had been demolished and a new petrol station was being constructed. In charge at the Seven Hills premises was Kieran Cosgrove. He was employed by Aspect Design & Development Pty Ltd ("Aspect") as a site foreman for the construction of the new petrol station. There were nine men working on the Seven Hills premises on 15 February 2002. During the three weeks prior to 15 February 2002, when earthworks were undertaken, Mr Cosgrove smelt odours that he associated with an old petrol station. Others also smelt odours from the former site in the months, weeks and days before 15 February 2002.
26 On Thursday 14 February 2002 a footing for a retaining wall on the site had been constructed on the Seven Hills premises. Groundwater was seeping into the trench. Mr Cosgrove contacted the defendant to arrange for the disposal of the construction groundwater. Mr Struthers arrived at the Seven Hills premises at approximately 9:30am on 15 February 2002. Mr Cosgrove showed Mr Struthers the groundwater that was required to be collected.
27 Mr Struthers could not collect the groundwater immediately because there was a truck in the side street between the Seven Hills premises and the two-storey office building, unloading mattresses. He waited until approximately 10:10am for the truck to leave. Then he reversed the tanker truck down the side street. He parked approximately adjacent to the footing and the groundwater. Mr Struthers operated the vacuum pump on the truck and Mr Cosgrove handled the hose attached to the truck and stood in the footing to direct the hose. Mr Struthers told the EPA that he had a conversation with Mr Cosgrove at some stage after he had started the vacuum pump, in the following terms. Referring to the tanker, words to the following effect were spoken:-
Mr Struthers said: "Is it offensive? Any fumes from that?"
Mr Cosgrove said: "No, it doesn't seem to be a problem to me. I don't notice it" .
28 Mr Struthers told the EPA he asked this because of the comments made by the Air International staff. If Mr Cosgrove had said it was offensive, Mr Struthers says he would not have continued and would have left the site. Mr Struthers detected the odour from the vacuum part of the tanker. He described it as "fumy". He said this was another reason he asked Mr Cosgrove the above question.
29 It took Mr Struthers about 15 minutes to collect 1.5 tonnes of groundwater from the Seven Hills premises.
30 The smell of petrol had been reported around the site since digging had commenced at the site, prior to the arrival of Mr Struthers. The fumes and odours had caused discomfort and illness to workers at adjoining premises.
31 As a result of the release of an odour from the tanker truck at the Seven Hills premises there were direct effects on a number of people. The impacts included headache, nausea, shortness of breath, light-headedness, vomiting, tightening of the chest, burning to the back of the throat, difficulty with breathing, coughing, burning to the tongue and mouth, throat closure and dry retching.
32 A number of people were inconvenienced for several days. Others went to Blacktown or Mount Druitt Hospital where they underwent tests and received treatment. A temporary hospital was established outside the nearby premises of K-Mart Tyres where a number of people were treated on the spot by Ambulance Officers and then taken to Blacktown Hospital for further treatment. As a result of the release of an odour from the tanker truck at the Seven Hills premises, approximately 23 people attended Blacktown, Westmead or Mr Druitt Hospitals. Mr Struthers did not attend any hospital, although he was checked by ambulance officers at the Lidcombe Liquid Waste Plant ("the LLWP").
33 Mr Struthers was not aware of the incident at the Seven Hills premises until he received a telephone call from Mr Hill when he arrived at the LLWP, where he provided a sample of the contents of the tanker truck to officers of the waste service.
34 In interviews conducted by the EPA with various employees of the defendant, including Mr Struthers and Mr Hill, it was accepted that if a driver of a tanker truck detects an offensive odour being emitted or a complaint is made during the collection of liquid waste, the following process should be followed:-
(i) turn off the vacuum pump to immediately cease the further emission of odours;
