Ethanol from Redox
24 On 24 April 2020, approximately 10,000L (8,080kg) of ethanol was delivered to the Premises, supplied by Redox Pty Ltd (the Redox ethanol). The Redox ethanol was contained in ten 1,000L IBCs, which were stored in the Flammable Goods Store until required for production.
25 Once the Redox ethanol was received, the Defendant started manufacturing hand sanitiser. By the time of the fire on 9-10 July 2020, most of the Redox ethanol had been consumed.
Ethanol from CRM
26 On 20 April 2020, the ethanol which the Defendant had ordered from CRM was loaded on board a vessel in Shanghai. It was shipped in 304 blue plastic 200L drums, stored in two shipping containers. CRM had advised Mr Cai that the ethanol would be shipped in plastic drums.
27 On 13 May 2020, Verus Global, a freight forwarding company, emailed Mr Cai and Mr Coronel advising that "4 semi loads" of ethanol were ready to be delivered to the Premises.
28 Subsequently, Ms Dong directed staff, including Mr Coronel, to store the new shipment of ethanol in the canopy area and to clear out the floor area to make room for the new ethanol. Staff of the Defendant cleaned the canopy area to make space for the ethanol. Items were moved around and some things were placed on racking, leaving a space in the canopy area for the ethanol.
29 Over two days, on 21 and 22 May 2020, the ethanol from CRM was delivered by truck to the Premises in 304 200L blue plastic drums. It consisted of 48,640kg (60,800L) of denatured ethanol 95% (the CRM ethanol). The drums were sitting on plastic pallets, four drums to a pallet. A copy of the receipt and MSDS for the CRM ethanol is [attached].
30 As shown in the photographs [attached], the pallets of drums of CRM ethanol were double-stacked by staff of the Defendant in the canopy area, adjacent to which was an east-west oriented grated stormwater drain. The following image is an extract of the stormwater diagram of the Premises [as attached], marked-up to show where the CRM ethanol was placed in relation to the drain (the image is orientated with south at the top of the diagram):
31 The drums of CRM ethanol were stored in the canopy area until required for production. From time to time, staff of the Defendant removed drums or pallets of the CRM ethanol using a forklift and took them to the production area as required. Once a drum of CRM ethanol was empty, it would be stored outside on a pallet on the driveway on the north-eastern side of the Premises. After the fire, around 80 empty blue plastic drums were found stored on pallets on the north-eastern driveway of the Premises.
32 The Defendant has estimated that 25,266kg (about 31,500L) of ethanol was being stored in the canopy area at the time of the fire, all of which was destroyed during the fire.
The Incident
33 At 6:22pm on 9 July 2020, Fire and Rescue NSW (FRNSW) were called to a fire at the Premises and a fire on the surface of Clinches Pond (the Incident).
34 Upon arrival, FRNSW officers observed a large fire at the southern end of the Premises (being the canopy area), which involved cardboard and blue drums marked with flammable liquid stickers. The fire was burning quite freely with flames around six to seven metres in height.
35 At around 6:35pm, upon evacuating staff from the Premises, FRNSW officers were advised that ethanol was possibly involved in the fire.
36 The fire consumed the blue plastic drums of CRM ethanol. As a result of the fire, ethanol descended from the burning drums and into the grated stormwater drain at the southern end of the Premises.
37 Whilst the precise volume of ethanol that descended into the drain is not known, all that remained after the fire was melted blue plastic on the floor of the canopy area.
38 As depicted in the stormwater drain map [attached], the ethanol travelled both east and west along the grated stormwater drain, then north towards the front of the Premises, across adjacent properties (Lots 1 and 2 in in DP847587) and into the stormwater drains along Church Road. Those stormwater drains drained into the south-western corner of Clinches Pond.
39 Blue flames were seen emanating from the stormwater drains. The flames were around knee-high in the grated stormwater drain at the southern end of the Premises, as depicted in the photographs [attached], and in the drains running down the middle of the driveway on the Premises towards Church Road. The blue colour of the flames was consistent with burning ethanol.
40 At an early stage, officers of the NSW Police Force (NSWPF) also saw Clinches Pond on fire. A photograph of the blue ring of fire which was observed by NSWPF officers on the surface of Clinches Pond is [attached].
41 By 7:45pm, FRNSW's Incident Controller had not been able to determine from people that worked at the Premises exactly where the ethanol was stored, how much was stored and whether it was bunded. As a result, he upgraded the fire to an "8th Alarm Structure Fire" meaning that over 145 firefighting and support personnel were deployed to the Premises to manage the Incident.
42 FRNSW notified the Environment Protection Authority (EPA) of the Incident.
43 Water was initially used to suppress the fire. FRNSW crews placed temporary bunding around some of the drains at the Premises and two lines of booms at the stormwater inlets into Clinches Pond. Covers were also placed over some of the drains at the Premises.
44 At about 10:50pm, FRNSW transitioned from using water to suppress the fire to using a firefighting foam called FOREXPAN S.
45 At about 1:30am on 10 July 2020, the fire was downgraded to a "3rd Alarm Structure Fire", as a consequence of which only about 50 firefighting and support personnel were required on site.
46 At around midday on 10 July 2020, two EPA officers attended the Premises. The fire remained active and the officers were unable to access the southern end of the Premises. Pools of dark odorous liquid were forming around stormwater drains at the front (north) of the Premises. The forecourt of the Premises also had a burnt sweet chemical odour. A rough diagram of the canopy area as seen after the fire, with the Flammable Goods Store next to it, drawn by FRNSW fire investigator Jack Edman, is [attached].
47 At nearby Clinches Pond, the liquid in two drainpipes entering the pond was still, with a slight film on the surface. Clinches Pond had a similar smell to that at the Premises, being a burnt sweet chemical odour.
48 The EPA officers collected water samples from a stormwater pit at the north of the Premises and at Clinches Pond. Ethanol was detected in the samples taken at both locations at the levels set out in the table [attached].
49 Two of the photographs taken by the EPA officers that day are [attached].
50 No cause of the fire was established.
First clean-up notice
51 On 11 July 2020, on an urgent basis, the EPA issued clean-up notice no. 1597376 to the Defendant pursuant to section 91 of the POEO Act. The notice directed the Defendant to take certain clean-up actions, including to remove contaminated water from pooled areas and stormwater pits at the Premises and assess whether contaminated water was leaving the Premises at any other location.
52 That same day, in response to the clean-up notice, Mr Edwards advised the EPA that he was arranging for vacuum trucks to remove contaminated water from the Premises.
53 The Defendant engaged Enviro Waste Services Group (Enviro Waste) to carry out the clean-up actions under the notice. Between 11 and 14 July, a total of 37,521Lof contaminated water was removed from the stormwater pits at the Premises.
Clinches Pond
54 On 21 July 2020, Mr Joel Daniels of Liverpool City Council (the Council) observed approximately 20 fish that were either dead or gasping for air, and eels that appeared to be dead or dying at Clinches Pond, in addition to turbid water and a strong odour. Mr Daniels contacted the EPA.
55 On 22 July 2020, EPA officers Ms Bernie Turner and Dr Ian Holland conducted an inspection of Clinches Pond.
56 Ms Turner observed a moderate to strong sweet chemical odour at various locations around Clinches Pond, an oily sheen on the surface of the water at the southern end, some dead fish floating on the surface and other fish gasping for air.
57 Dr Holland observed a scum layer on the surface of the water, several large dead fish and a strong odour reminiscent of decaying food waste at the southern end of Clinches Pond.
58 Photographs taken by Ms Turner and Dr Holland on 22 July 2020 are [attached].
59 Dr Holland collected water samples at various locations around Clinches Pond and at Anzac Creek, the latter being a creek connected to Clinches Pond via approximately 700m of closed and open stormwater drains.
60 All water samples taken from Clinches Pond were found to be toxic. The levels of ethanol detected in those samples are set out in the table [attached]. The ethanol concentrations in the samples taken from the southern boundary of Clinches Pond showed a consistently high level of ethanol ranging from 70,500 µg/L to 75,200 µg/L. Ethanol was detected at lower, though still very high, concentrations at the northern end of Clinches Pond (34,800 μg/L).
61 The concentrations of ethanol in Clinches Pond on 22 July 2020 were significantly higher than on 10 July 2020, indicating that ethanol had continued to migrate from stormwater pits located on the Premises over this time period and accumulated along the southern end of Clinches Pond. From 11-15 July 2020, there was 23.8mm of rain in the Moorebank area, which would have been sufficient to facilitate migration of ethanol from any pooling locations within the stormwater system downstream to Clinches Pond. In addition, ethanol still sitting in the stormwater system may have been flushed out to Clinches Pond by the rainfall event of 8-10 August 2020.
62 The concentrations of ethanol in Clinches Pond were well in excess of the Australian & New Zealand Guidelines for Fresh & Marine Water Quality's default guideline value for ethanol of 1,400 μg/L for freshwaters. Those guidelines provide a standardised tool for assessing water quality for the protection of aquatic ecosystems.
63 These concentrations were also well in excess of the concentration required to completely deplete the oxygen in the pond. Dissolved oxygen levels at the sampled locations ranged from 0.03-0.19 mg/L. For most temperate aquatic animals, sustained dissolved oxygen levels below 4 mg/L can trigger some form of hypoxic stress, whereby the animal starts to implement behaviours or unconscious physiological means to increase oxygen uptake. The critical oxygen level for fish - which is the oxygen concentration below which a fish can no longer regulate internal oxygen levels to maintain a stable state, such that the animal will be under acute oxygen stress - is typically approximately 2 mg/L.
64 On 24 July 2020, a witness reported to the EPA that there were hundreds of dead fish in Clinches Pond and birds "hobbling around".
65 The sample from further downstream at Anzac Creek had undetectable levels of ethanol and was found not to be toxic.
Second clean-up notice
66 On 24 July 2020, on an urgent basis, clean-up notice no. 1597849 was issued to the Defendant pursuant to section 91 of the POEO Act. This required the Defendant to take certain clean-up actions at the Premises and at Clinches Pond.
67 The Defendant again engaged Enviro Waste to carry out the clean-up actions under the notice.
68 In complying with the clean-up notice, Enviro Waste, on behalf of the Defendant:
(a) collected and removed 209,870L of contaminated water from the Premises;
(b) collected and removed 1,418,120L of contaminated water from Clinches Pond; and
(c) collected and disposed of approximately 1 to 1.5 IBCs of dead fish and eels from Clinches Pond;
between 24 and 28 July 2020.
69 Photographs taken by employees of Enviro Waste during the clean-up are [attached]. This includes one photo of dead fish inside a 1,000L white plastic IBC.
70 On 6 August 2020, EPA officers inspected and collected water samples from the Premises and Clinches Pond. Ethanol was detected in the water samples taken at both locations at the levels set out in the table [attached]. The ethanol concentrations were lower than those previously recorded, which was likely due to both the clean-up activities carried out on behalf of the Defendant and the continued biodegradation of the ethanol. However, ethanol concentration levels were still found to be toxic in all samples. Measured dissolved oxygen levels in Clinches Pond ranged from 0.46-0.63 mg/L, well below the critical oxygen levels required to support aerobic aquatic life. Photographs taken by EPA officers on that day are [attached].
71 On 6 August 2020, a plumber for the Defendant concreted up three stormwater pipes at the Premises in an effort to prevent liquid leaving the Premises via the stormwater system.
72 As required by the second clean-up notice, the Defendant conducted water sampling at stormwater outfalls to Clinches Pond for a period of five weeks, between 29 July 2020 and 27 August 2020. Those results indicated that ethanol was present in the stormwater system until at least 12 August 2020.
73 On 3 September 2020, EPA officers collected further water samples from Clinches Pond. Ethanol was detected in the samples at the levels set out in the table [attached]. Although ethanol concentrations were far lower than on 6 August 2020, dissolved oxygen levels throughout Clinches Pond remained below the critical oxygen levels required to sustain aerobic aquatic life, with concentrations of just 0.11 mg/L at the southern and northern shorelines and 1.26 mg/L at the stormwater outflow.
74 On 4 November 2020, the Defendant provided the EPA with a report prepared by RARE Environmental Pty Ltd detailing actions taken by, or on behalf of, the Defendant in compliance with the two clean-up notices which is [attached].
Cooperation with EPA investigation
75 The Defendant cooperated with the EPA's investigation.
Prior convictions
76 The Defendant has no prior convictions for environmental offences.
Harm to the environment
77 Prior to the Defendant's offence, Clinches Pond was in relatively good ecological condition for an urban pond. The evidence suggests that despite intermittent impacts from local stormwater runoff, the pond ecosystem was capable of supporting an array of aquatic life in its waters, was adequately oxygenated for aerobic respiration and had not been previously impacted by catastrophic pollution.
78 The Defendant's offence caused serious environmental harm. The pollution of the waters of Clinches Pond with ethanol had a significant impact on the physical, chemical and biological condition of the waters.
79 The offence resulted in the waters of Clinches Pond becoming toxic. It also resulted in the catastrophic depletion of oxygen throughout Clinches Pond due to the oxygen demands of ethanol biodegradation. This made the pond uninhabitable for aerobic aquatic organisms. In particular, the offence caused the death of a large number of fish and eels, including european carp Cyprinus carpio, goldfish Carassius auratus, longfinned eels Anguilla reinhardtii and freshwater catfish Tandanus tandanus.
80 Despite the clean-up actions undertaken by Enviro Waste between 25 and 28 July 2020 - including the removal of 1,418,120L of contaminated water from Clinches Pond - Clinches Pond remained polluted with ethanol until 3 September 2020. It is estimated that it may take until approximately July 2022 for the ecosystem at Clinches Pond to completely recover, although recovery of a significant biomass of larger fish could take several years.
81 There is some evidence that oils held on the Premises by the Defendant, including fish oil, linseed oil, sunflower oil and cottonseed oil, were present in water samples taken by FRNSW at the Premises and the stormwater outlet to Clinches Pond on 10 July 2020. The biodegradation of these oils can be expected to have contributed to the lowering of dissolved oxygen in Clinches Pond. In addition, the use by FRNSW officers of fire-fighting foam containing butoxyethoxyethanol had the potential to contribute to the depletion of dissolved oxygen in Clinches Pond and thus to the death of fish and eels. However, biodegradation of the relatively high levels of the more readily biodegradable ethanol would have made a more significant contribution to the oxygen demand.
82 The Defendant's offence interfered with the amenity of the Moorebank area. In July and August 2020, concerned residents contacted the EPA and the Council about the condition of Clinches Pond. In addition, in early August, there was still an odour emanating from Clinches Pond that caused at least one local resident to keep the windows and doors of her home closed to prevent the smell entering.
83 The Defendant is no longer operating on the Premises and the land has been sold to a third-party company, Dexus Wholesale Management Limited.
Plea
84 On 10 September 2021, the Defendant entered a plea of not guilty.
85 On 11 February 2022, counsel for the Defendant indicated to senior counsel for the Prosecutor that the Defendant would plead guilty to the charge.
Remorse
86 The Defendant is remorseful for the harm and adverse impact that the fire has had on the environment.
- In addition to the facts that were agreed the Prosecutor adduced evidence to establish further facts relating to the circumstances surrounding the Defendant's decision-making in the ordering and storing of the CRM ethanol together with the actions that could have been taken by the Defendant to prevent, control, abate, or mitigate the harm that was experienced as a result of the offending.
