HARM
68. Over the course of about 10 minutes, between 11,260 and 11,766 litres of diesel escaped from the Fuel Tanker onto concrete.
69. The diesel flowed over land and entered the stormwater system located at the rear of the Premises. The diesel subsequently flowed downstream in the stormwater system into Mittagong Creek.
70. The spill caused actual and likely environmental harm to water, and likely environmental harm to land.
Expert analysis of harm to the environment
Mr Adrian Dickson
71. On 22 May 2023, Mr Adrian Dickson of OPE provided an expert opinion as to the freshwater ecological impact of the Incident on Mittagong Creek. Mr Dickson's assessment focuses on aquatic macroinvertebrates. Mr Dickson has tertiary qualifications in ecology and environmental science, and has had 20 years' experience working as a researcher, consultant and scientist in the field of freshwater ecology. Mr Dickson has predominately worked in the field of river health assessment using macroinvertebrates as biological indicators of stream and ecosystem condition. Mr Dickson is currently a senior scientist for river assessment for OPE.
72. On 23 June 2022, staff from OPE collected macroinvertebrate samples from Mittagong Creek with samples collected both upstream and downstream of the stormwater discharge point.
73. Following an analysis of the samples collected and from a review of relevant data, Mr Dickson found:
a. the results of water quality data of samples collected following the incident suggests that the contaminant (diesel) entered Mittagong Creek from the stormwater discharge point.
b. The results of the total abundance and the abundance weighted SIGNAL2-Family results indicated significant differences between upstream and downstream samples, with significantly lower populations in the downstream samples.
c. BEST (BIOENV) analysis demonstrated that the main environmental variables that helped to differentiate macroinvertebrate community composition were based on location (Latitude), and this was true of both data sets with and without the Gastropoda taxa removed. As such, the variability of the community observed when comparing upstream and downstream macroinvertebrate samples results, and the variability between the two downstream sites, must be due to other factors. In Mr Dickson's opinion there was a high likelihood that the contaminant (diesel) was responsible for differences observed between upstream and downstream macroinvertebrate samples.
d. The results of the multivariate analysis suggest differences in the macroinvertebrate community of sites upstream and downstream of the contaminant (diesel) discharge that could not be contributed to differences in physical habitat, in situ water quality or even the dissolution of calcium carbonate from concrete surfaces.
74. Based on the results of the 23 June 2022 sampling as well as EPA sampling results from 4, 12 and 30 June 2022 (as well as sampling from Park's consultants), Mr Dickson concluded that:
a. The contaminant (diesel) entered Mittagong Creek from the stormwater discharge point and the waters downstream was toxic to aquatic life.
b. Based on the 4 June 2022 EPA sample results, the diesel that entered the stormwater system and Mittagong Creek changed the chemical and biological condition of the waters.
c. Based on the sampling results of 4 June 2022 and macroinvertebrate samples collected on 23 June 2022, there was actual harm to the environment due to the impact on water quality and aquatic biota of the receiving environment in Mittagong Creek. This harm likely extended approximately 1km downstream.
d. Based on the EPA sampling results of 4 and 12 June 2022, the harm to the aquatic ecosystem in Mittagong Creek was not trivial.
e. The samples collected on 4 June 2022 of the Mittagong Creek downstream from the discharge point found the water to be "Toxic - requires >100 times dilution to remove toxicity". While there was likely some background level of contaminants in Mittagong Creek, sampling upstream on 12 June 2022 suggested that the background contamination was (sic) "requires 2 times dilution to remove toxicity" and therefore the water downstream of the discharge point was 50 times more toxic than upstream of the discharge point.
f. The impact on the macroinvertebrate included a difference in composition and fewer families than expected which suggests a loss of taxa.
g. In any event, the presence of any amount of diesel in a freshwater ecosystem is highly likely to cause harm, or at the very least threaten harm, to aquatic biota, especially those that dwell near or on the water's surface, which is where the diesel would likely be given the low flow, slow moving nature of the waterway at and following the time of the Incident. Many macroinvertebrate taxa, such as Hemiptera (True bugs) which includes water boatmen, backswimmers and water striders, use the water's surface tension to navigate through their habitat and any changes to the chemical composition of the water can change surface tension and cause these surface-dwelling taxa to which can be fatal for some of these taxa.
h. In addition, the Incident had the potential to disrupt the feeding and predatory avoidance strategies that these, and other taxa employ to survive. Furthermore, taxa such as Odonata (dragonflies and damselflies) lay eggs directly in the water while flying above it and they rely on surface tension to facilitate contact with the water and dispersal of eggs into the water and on floating and emergent aquatic vegetation. The presence of contaminants, such as diesel, can disrupt this process and can cause these taxa to fall into the water and become engulfed in the contaminant.
i. There is no evidence that the Incident caused actual or potential harm to the Wingecarribee River located approximately 5km from the Incident.
Laureate Professor Ravi Naidu
75. On 4 July 2023, Laureate Professor Ravi Naidu provided an expert opinion as to the ecological impact of the Incident on the land located at the Premises and the waters located at the Premises' stormwater system and downstream to Mittagong Creek. Professor Naidu has a PHO in soil chemistry as well as other tertiary qualifications in soil and science. Professor Naidu has over 35 years of experience in the field of environmental science, which includes assessing, characterising risks and remediating contaminated soil and water, as well as assessing the potential impacts of contaminants on the environment and human health. Professor Naidu is currently the Managing Director and CEO of the Cooperative Research Centre for Contamination Assessment and Remediation of the Environment (crcCARE), an independent organisation that performs research, develops technologies and provides policy guidance for assessing, cleaning up and preventing contamination of soil, water and air.
76. Following an analysis of samples collected by the EPA and OPE on 4, 9, 12, 23 and 30 June 2022 (as well as sampling from Park's consultants) and from a review of relevant data, Professor Naidu found that:
a. Diesel is a prescribed matter for the purposes of Schedule 5 of the Protection of Environment Operations (General) Regulation 2021 because it is a fuel oil which is flammable and when spilled in water adversely impact the chemical conditions of the water including pH, chemical oxygen demand and biochemical oxygen demand.
b. Diesel is a hazardous chemical and is toxic and poses acute risks to people, property and environment due to the chemical or physical characteristics.
c. All diesel contains a mixture of hydrocarbon compounds such as benezene, toluene and xylene and polycyclic aromatic hydrocarbons which are known to be toxic to aquatic life and can cause harm to human health.
d. A soil sample taken from the Premises on 4 June 2022 exceeded acceptable soil health screening levels for direct contact at open space area by two times and ecological screening levels for total petroleum hydrocarbon fractions by 45 times.
e. A soil sample taken from the Premises on 9 June 2022 exceeded twofold acceptable soil health screening levels for direct soil contact at commercial and industrial area and 135 times the ecological screening levels.
f. Water samples collected on 4 June 2022, 200m downstream of the stormwater discharge point into Mittagong Creek was tested above regulatory criteria for freshwater quality guideline values of Australian Drinking Water Guidelines.
g. Based on EPA samples taken on 4 and 12 June 2022, the diesel that entered the stormwater system and Mittagong Creek made the waters toxic.
h. Data from a groundwater well study of the Premises on 21 February 2023 shows detectable concentrations of hydrocarbons at the shallow groundwater well GW01 (1 .7 m bgl) (benzene (4 µg/L) and TPH fractions (>C10-C16 Fraction (F2) (170 µg/L), >C16-C34 Fraction (F3) (160 µg/L) and >C34-C40 Fraction (F4) (below laboratory reporting limit)). There were no chemicals of concern detected in samples from the deeper wells (GW02 and GW03 approximate depth of water 3 m bgl).
77. With respect to the impact on the land located at the Premises, Professor Naidu concluded that:
a. The spill degraded the land located at the rear of the Premises and resulted in potential risk to humans, animals, terrestrial life and ecosystems that was not trivial. Professor Ravi noted that on 4 June 2022 an EPA officer observed dead earthworms that were impacted by the oily residues at the Premises.
b. The results from 4 June 2022 indicate substantial contamination and degradation of the soil from the Incident.
c. The diesel had a non-trivial impact on the soil at the Premises.
d. In any event, diesel contains a mixture of hydrocarbons which are likely to cause significant harm to the environment and ecosystems in the area surrounding a spill.
e. The diesel can also seep into groundwater and nearby bodies of water, further spreading the contamination. Based on results from groundwater wells, it is likely that the diesel contamination from the Incident resulted in groundwater contamination.
f. However, chronic exposure from the diesel was avoided due to remediation measures undertaken to excavate and dispose the contaminated soil in an off-site landfill facility.
78. With respect to the impact on the stormwater system and Mittagong Creek, Professor Naidu concluded that:
a. The diesel that entered the stormwater system and Mittagong Creek changed the physical, chemical and biological condition of the waters.
b. The diesel made the water in the stormwater system and Mittagong Creek unclean, noxious, poisonous and impure.It also made the stormwater poisonous or harmful to aquatic life but it returned to acceptable condition by 23 June 2022.
c. The introduction of the diesel to Mittagong Creek severely impacted the quality of water and had an impact on the stormwater system and Mittagong Creek that was not trivial.
d. The diesel severely impacted Mittagong Creek until late June however, the diesel was diluted by heavy rain in July 2022.
e. In the absence of this rainfall, the adverse impact of diesel on stream water quality in Mittagong Creek would have persisted for a much longer period.
f. The introduction of diesel created oil slicks which reduced the amount of light that penetrates the water and can impact upon the growth of aquatic plants, which can also cause distress to aquatic organisms due to murky and cloudy conditions.
g. The introduction of diesel into waterways, specifically in the case of the receiving ecological system in Mittagong Creek, can have adverse effects on aquatic organisms. The dissolved phase of diesel present in the water (the part of diesel contamination which has dissolved/partitioned into water) can impede the ability of fish and other aquatic organisms to breathe.
h. In any event, a diesel spill has the potential to cause immediate and harmful consequences to an ecosystem's health and the well-being of aquatic life.
CRIMINAL HISTORY
79. Mr Routledge has no known prior convictions for environmental offences.
In my opinion, the above ground diesel storage tank located at Highland Fuels Bowral has no operational mechanical or electrical faults which may have contributed to this fuel spill. However, the design of the tank pipework allowed for discharge from the filling point. This is in contradiction to AS1940:2017- The Storage and Handling of Flammable and Combustible Liquids, which stipulates a check valve is required to ensure "backflow cannot occur when the filling hose has been disconnected". This was not the cause of the spill. However, the flow of diesel back to the tanker would not have occurred if this check valve was installed.

(ii) the offender has acknowledged any injury, loss or damage caused by his or her actions or made reparation for such injury, loss or damage (or both),
...
(k) a plea of guilty by the offender (as provided by section 22 or Division 1A),
...
(m) assistance by the offender to law enforcement authorities (as provided by section 23),
22 Guilty plea to be taken into account for offences not dealt with on indictment
(1) In passing sentence for an offence on an offender who has pleaded guilty to the offence, a court must take into account -
(a) the fact that the offender has pleaded guilty, and
(b) when the offender pleaded guilty or indicated an intention to plead guilty, and
(c) the circumstances in which the offender indicated an intention to plead guilty,
and may accordingly impose a lesser penalty than it would otherwise have imposed.
(1A) A lesser penalty imposed under this section must not be unreasonably disproportionate to the nature and circumstances of the offence.
23 Power to reduce penalties for assistance provided to law enforcement authorities
(1) A court may impose a lesser penalty than it would otherwise impose on an offender, having regard to the degree to which the offender has assisted, or undertaken to assist, law enforcement authorities in the prevention, detection or investigation of, or in proceedings relating to, the offence concerned or any other offence.
241 Matters to be considered in imposing penalty
(1) In imposing a penalty for an offence against this Act or the regulations, the court is to take into consideration the following (so far as they are relevant) -
(a) the extent of the harm caused or likely to be caused to the environment by the commission of the offence,
(b) the practical measures that may be taken to prevent, control, abate or mitigate that harm,
(c) the extent to which the person who committed the offence could reasonably have foreseen the harm caused or likely to be caused to the environment by the commission of the offence,
(d) the extent to which the person who committed the offence had control over the causes that gave rise to the offence,
(e) whether, in committing the offence, the person was complying with orders from an employer or supervising employee,
(f) the presence of asbestos in the environment.
(2) The court may take into consideration other matters that it considers relevant.
A sentence should never exceed that which can be justified as appropriate or proportionate to the gravity of the crime considered in light of its subjective circumstances: Bentley v BGP Properties Pty Ltd [2006] NSWLEC 34; (2006) 145 LGERA 234 at [162].
The objects of this Act are as follows:
(a) to protect, restore and enhance the quality of the environment in New South Wales, having regard to the need to maintain ecologically sustainable development,
(d) to reduce risks to human health and prevent the degradation of the environment by the use of mechanisms that promote the following:
(i) pollution prevention and cleaner production,
(ii) the reduction to harmless levels of the discharge of substances likely to cause harm to the environment,
(iia) the elimination of harmful wastes,
...
(e) to rationalise, simplify and strengthen the regulatory framework for environment protection,
(f) to improve the efficiency of administration of the environment protection legislation,
...
The extent of the harm caused or likely to be caused to the environment by the commission of the offence: s 241(1)(a) of the POEO Act
harm to the environment includes any direct or indirect alteration of the environment that has the effect of degrading the environment and, without limiting the generality of the above, includes any act or omission that results in pollution.
environment means components of the earth, including:
(a) land, air and water, and
(b) any layer of the atmosphere, and
(c) any organic or inorganic matter and any living organism, and
(d) human-made or modified structures and areas,
and includes interacting natural ecosystems that include components referred to in paragraphs (a)-(c).
(1) harm is not limited to measurable harm such as actual harm to human health, and can include a broader notion of quality of life;
(2) harm can include harm to the environment and its ecology; and
(3) harm can be direct or indirect, individual or cumulative; and the culpability of the defendant depends in part on the seriousness of the environmental harm.
Reasons for committing the offence and state of mind of the offender
Reasonable foreseeability of the harm caused or likely to be caused by the commission of the offences
Control over causes and practical measure that could have been undertaken
Assistance to EPA - s 21A(3)(m) and s 23 of the CSP Act
(1) The preparation of the ASOF;
(2) His participation in a formal record of interview; and
(3) The preparation of an affidavit to assist the EPA in its prosecution of his former employer Park Pty Limited.
Early plea of guilty - s 22 and s 21A(3)(k) of the CSP Act
139 The sentence must serve the purpose of general or public deterrence. It is the duty of the Court to see that the sentence which is imposed will operate as a powerful factor in preventing the commission of similar crimes by those who might otherwise be tempted by the prospect that only light punishment will be imposed: R v Rushby [1977] 1 NSWLR 594 at 597-598.
140 This factor is particularly relevant to environmental offences. Persons will not be deterred from committing environmental offences by nominal fines: Environment Protection Authority v Capdate Pty Ltd (1993) 78 LGERA 349 at 354 and Director General, National Parks and Wildlife v Wilkinson [2002] NSWLEC 171 (27 September 2002) at [85] and [93] per Lloyd J.
To the extent to which two offences of which an offender stands convicted contain common elements, it would be wrong to punish that offender twice for the commission of the elements that are common. No doubt that general principle must yield to any contrary legislative intention, but the punishment to be exacted should reflect what an offender has done; it should not be affected by the way in which the boundaries of particular offences are drawn. Often those boundaries will be drawn in a way that means that offences overlap. To punish an offender twice if conduct falls in that area of overlap would be to punish offenders according to the accidents of legislative history, rather than according to their just deserts.
6 Consideration of accused's means to pay
In the exercise by a court of a discretion to fix the amount of any fine, the court is required to consider-
(a) such information regarding the means of the accused as is reasonably and practicably available to the court for consideration, and
(b) such other matters as, in the opinion of the court, are relevant to the fixing of that amount.
(1) Charge 1: $50,000, less 25% for early guilty plea resulting in a fine of $37,500; and
(2) Charge 2: $50,000, less 25% to take into account the principle of totality and 25% for early guilty plea resulting in a fine of $28,125.
(1) Charge 1: $11,250; and
(2) Charge 2: $8,437.50.
(1) The Defendant is convicted as charged;
(2) The Defendant is fined the sum of $11,250;
(3) The Defendant is to pay the Prosecutor's legal costs of the proceedings in the amount as may be determined under s 257B of the Criminal Procedure Act 1986 (NSW);
(4) The Defendant is to pay the Prosecutor's investigation costs in the agreed sum of $8,849.25 pursuant to s 248(1) of the Protection of the Environment Operations Act 1997 (NSW); and
(5) Pursuant to s 122 of the Fines Act 1996 (NSW), a moiety of 50% of any fine determined by the Court be paid to the EPA.
(1) The Defendant is convicted as charged;
(2) The Defendant is fined the sum of $8,437.50;
