The Court Should Decline to Exercise its Discretion to Reopen or Vary the Orders
46Even if the conclusion above is incorrect, I would nevertheless dismiss the application because the Foxman entities have not demonstrated "sufficient cause" to warrant the exercise of the discretion.
47The Foxman entities submitted that two events that had occurred subsequent to the reservation of the decision and prior to its publication amounted to sufficient cause for the purpose of order 13. These were that:
(a)first, on 16 May 2013, the National Environment Protection (Assessment of Site Contamination) Measure 1999 ("the National Measure") was amended by the National Environment Protection Council. This amendment has since been endorsed by the New South Wales Environment Protection Authority ("NSW EPA"). Accordingly, there has been a recent adoption of a new nationally consistent approach to the assessment of site contamination. The amended National Measure emphasises that the assessment and management of asbestos contamination should take into account the very low human health risk posed by most occurrences of soil contamination by bonded asbestos. The approach advocates that, where there is a very low human health risk in the circumstances, remediation options for asbestos which minimise soil disturbance are preferable; and
(b)second, no significant instability has occurred to the fill areas and batters on the land. Grass cover and revegetation on the site has assisted with the stability and control of surface erosion.
48The Foxman entities relied upon the following evidence in support of their proposed orders:
(a)an affidavit of Mr Brian Furr sworn 2 August 2013. Mr Furr is the principal environmental scientist at JBS&G (NSW & WA) Pty Ltd ("JBS&G"). Mr Furr is an expert in the field of land contamination. In expressing his opinions, Mr Furr had regard to the National Measure and the Guidelines for the Assessment, Remediation and Management of Asbestos-Contaminated Sites in Western Australia, WA Department of Health, 2009 ("the 2009 Guidelines"). He noted that the 2009 Guidelines had, similar to the National Measure, since been endorsed by the NSW EPA under the provisions of the Contaminated Land Management Act 1997, as part of the 2013 amendments to the National Measure. It was Mr Furr's opinion that, having regard to the amount of time that the material had been situated on the land, and having regard to the vegetation cover, the "removal of the material would now present a greater risk to human health than retaining the material on site, subject to implementation of a remediation action plan". Moreover, it was his view that, the fill material on site did not represent a serious risk to human health because only bonded asbestos fragments had been discovered at the surface of the fill material and no asbestos fibres, and, in particular, no airborne asbestos fibres, had been detected in any analysis or monitoring conducted of the fill material on site. With the implementation of an Environmental Management Plan ("the EMP") that JBS&G had prepared in relation to the land, Mr Furr was of the opinion that in its current state, if left undisturbed, the potential for release of asbestos fibres was minimal and in-situ capping and ongoing management was sufficient to remediate the land. It was his opinion that the removal of the material for disposal offsite would present an unnecessary increased risk of potential exposure to asbestos for workers conducting the removal works and the general public;
(b)the EMP prepared by JBS&G dated 30 August 2013 for the management of the asbestos on the land. JBS&G opined that with the EMP in place, the site could be considered to be suitable for rural use;
(c)a Remedial Action Plan ("RAP") also prepared by JBS&G dated 30 August 2013. The RAP was said to be consistent with, amongst other things, the National Measure. The RAP concluded that both the eastern and western fill areas were considered to be impacted with bonded asbestos and required remediation. The preferred remediation strategy (contained in section 5.4 of the RAP) was the consolidation and isolation of the soil by onsite containment within a properly designed barrier and ongoing management in accordance with the EMP. The RAP "noted that there must be acceptance by the ultimate custodian of the land that future controls will be implemented, and that a notation will be made on the Title of the land". All surface asbestos was to be removed by hand picking and disposed of at an appropriately licensed waste disposal facility; and
(d)a report by JK Geotechnics dated 26 July 2013 by Mr Bruce Walker. The report stated that the conditions that Mr Walker had observed during a site survey on 21 June 2013 were similar to those in 2010 except that there had been substantial revegetation of the batters and areas affected by earthworks carried out prior to his 2010 report. While he did not observe any examples of overall instability of the batters and works, he noted that there were signs of movement in some of the locations. In particular, in the western fill area tension cracks were present. In the eastern fill area there was a localised small slope failure and the presence of tension cracks at the edges of major fill batters. It was Mr Walker's opinion that "the presence of tension cracks at the edges of the major fill batters in the Western and Eastern Fill Areas is indicative of poor compaction and possible future edge slumping/instability during periods of wet weather". He recommended that maintenance work be carried out as soon as possible to infill the tension cracks and improve surface water drainage to reduce the possibility of instability or slumping occurring. In the remaining fill areas and the fire trails, in order to achieve the widths to comply with Rural Fire Services requirements, he "still consider[ed] that the remedial works discussed in [his] 2010 Report, and as agreed in the Joint Expert Conferences, should be carried out to provide adequate stability in the long term."
49The council relied upon an affidavit of Dr Daniel Martens sworn 13 September 2013. Dr Martens reviewed the material contained in Mr Furr's affidavit, the EMP, the RAP and the geotechnical report of JK Geotechnics. Having been asked to comment upon whether or not there were any changed circumstances concerning the controls and/or measures that would cause him to alter the opinions expressed by him earlier in the proceedings (Wollondilly (No 5) at [147]-[151] and [153]), he answered in the negative.
50His reasons were as follows:
(a)the JK Geotechnics geotechnical report noted a number of indications of slope instability within the fill material, that would require substantial remedial works in order for it to be stabilised. Thus, if anything, the geotechnical conditions at the site had worsened;
(b)the RAP did not provide any new data in relation to the contamination of the land. If anything, it recommended that further testing and evaluation be undertaken in order to properly characterise the fill material;
(c)the EMP did not provide any new data in relation to the site contamination;
(d)the affidavit of Mr Furr did not provide any new data in relation to the land. Moreover, Mr Furr had conducted, by his own admission, only an "ad hoc" inspection of the land on 25 June 2013. There was no evidence, in Dr Martens' opinion, to justify the assertion that the soil contamination and sampling undertaken in 2011 was generally in accordance with the National Measure. To the contrary, it had been Dr Martens' evidence during the hearing that sampling sufficient to meet the National Measure had not been undertaken (Wollondilly (No 5) at [149]). Finally, there was no evidence to support Mr Furr's conclusion that the removal of the material would present a greater risk to human health than retaining the material on site subject to the implementation of the RAP. Again, to the contrary, it was Dr Martens' view that in order to retain the fill on site, substantial earthworks would be required in order to, first, stabilise the fill, and second, cap it. As the JK Geotechnics report demonstrated, the fill remains in an unstable condition; and
(e)it was his firm opinion that removal of the fill material remained the "simplest and lowest risk option for site remediation". There was nothing that he had seen in the material provided by the Foxman entities in support of the proposed orders that had caused him to change his mind in this regard.
51None of the authors of the various expert reports were cross-examined.
52I accept the evidence of Dr Martens. With the exception of the amendment in 2013 to the National Measure and the adoption by the NSW EPA of the 2009 Guidelines, there have been no changed circumstances, other than the deterioration in the stability of some of the waste material deposited on the land, that would warrant the Court being satisfied that "sufficient cause" had been demonstrated in order to enliven the jurisdiction of the Court to exercise the reserved discretion and to make the orders sought pursuant to the liberty to apply, or in the alternative, to, in fact, exercise that discretion.
53The material relied upon by the Foxman entities amounts to an attempt to reagitate the principal findings made in the proceedings. Put bluntly, the Foxman entities are seeking, through the vehicle of the proposed orders, what can only be described as a second bite of the cherry.
54Nowhere is this more evident than when examining the degree to which the orders proposed by the Foxman entities are inconsistent with the Court's findings of fact and law as set out in the judgment and with the relief granted by the Court.
55The Court found that the fill material as deposited on the land was "waste" within the meaning of the POEOA and met neither the 2008 nor 2010 waste exemptions (at [92]-[210]). Further, the Court found that there was widespread presence of asbestos throughout the fill material (at [217]-[219]) and that the land was being used as a "waste facility", as that term is defined in the POEOA (at [224]-[225]). Moreover, the Court held that the land could not lawfully be used as a waste facility for that waste. The Court also found that the filling of the land with the waste constituted a "land filling operation" as that term is defined in the Wollondilly Local Environmental Plan 1991 ("the LEP") (at [264]-[266]), and that this use of the land constituted a "waste management facility or works" under the EPAA (at [267]-[270]). Finally, in the 2011 proceedings (40062 of 2011) the Court held that the development described in the 2010 Statement of Environmental Effects prepared in respect of the land was designated development (at [291]-[307]).
56The proposed orders stand in conflict with these findings, and the judgment read as a whole, because the Foxman entities are asking the Court to make orders which would, in effect:
(a)permit the land to continue to be used unlawfully as a "waste facility" in contravention of s 144 of the POEOA;
(b)permit the land to continue to be used as a "land filling operation", as defined in the LEP, absent the necessary development consent having been obtained to use the land for that purpose, contrary to s 76A of the EPAA;
(c)permit the land to continue to be used as a "waste management facility or works" as defined in the Environmental Planning and Assessment Regulation 2000, being a form of designated development for which there was no consent, again in contravention of s 76A of the EPAA;
(d)conflict with order 2 insofar as the Court would be permitting the Foxman entities to do that which the Court had restrained them from doing; and
(e)conflict with order 8 insofar as the Court would be permitting the ongoing use of land as a waste facility contrary to the terms of the restraint imposed in that order in circumstances where there was no evidence to suggest that the requisite permits had been obtained.
57In addition, in my opinion, the emphasis placed on the National Measure, as amended in 2013 is exaggerated. First, it must be remembered that the National Measure is no more than a guideline with no binding force.
58Second, as the National Measure itself states (emphasis added):
This guidance is not applicable to asbestos materials which are:
· waste such as demolition materials present on the surface of the land...
This description is apt for the waste fill material that has been deposited on the land.
59Third, as the National Measure itself states, if visible asbestos is present and may be disturbed during work activities, it must be removed. This includes "removing visible fragments of bonded [asbestos] from ...those areas of the site where intrusive works may be carried out... Visible asbestos should be removed prior to excavation/construction works commencing". Thus the import of National Measure is not as equivocal as that submitted by the Foxman entities in respect of leaving asbestos contaminated soils and material in-situ.
60Fourth, while the National Measure emphasises that asbestos only poses a risk to human health when fibres are made airborne and inhaled, and hence if it is bound in a matrix such as cement or resin (capping) it will not be readily made airborne except through substantial physical damage (see section 4.6), as the geotechnical evidence discussed in Wollondilly (No 5) demonstrates, and as confirmed in the recent report of Mr Walker dated 26 July 2013, further handling of the fill, including compaction and the requirement for additional fill to be added to the land (Wollondilly (No 5) at [176]-[178] and [288]) raises a real risk that substantial physical damage could occur to the bonded asbestos present in the waste material thereby causing airborne asbestos fibres to be released. In my view, therefore, the National Measure not only does not assist the Foxman entities in the circumstances of this case, its amendment and adoption after the decision was reserved is insufficient to amount to a sufficient cause for the Court to exercise its discretion pursuant to the liberty to apply for the purpose of making the proposed orders.
61The reasons discussed above in respect of the National Measure resonate with equal force in relation to the 2009 Guidelines. These were the subject of expert evidence and discussion before the Court (Wollondilly (No 5) at [149], [153] and [287]-[288]). The Court considered these Guidelines in the exercise of its discretion to grant the relief sought. That they have been subsequently endorsed by the NSW EPA does not cause the Court to resile from the findings and orders previously made. That the 2009 Guidelines were only in draft form when last considered by the Court is immaterial.
62In any event, the Court must weigh up matters in addition to those contained in the National Measure and the 2009 Guidelines. In exercising its discretion pursuant to order 13, the Court must also have regard to any other considerations that inform the exercise of its power. These include the matters set out in the judgment concerning the circumstances of and by which the land was contaminated with waste (Wollondilly (No 5) at [102]-[103]). For example:
(a)the evidence of Dr Martens as to the extensive quantity of asbestos distributed throughout the fill material and, although the asbestos is bonded, the fact that the fill will require further handling by earthmoving machinery in order to render it stable thereby importing the risk of breaking, or further breaking, down the asbestos and releasing harmful fibres (at [288(f)]);
(b)the evidence of Dr Martens stating that although entombment or capping of the waste is possible, this would be difficult on the land because of the steep slopes, the nature of the soils and the presence of ridge lines and valleys (at [288(f)]);
(c)the finding that it was not possible to simply remove "hot spots" of asbestos contamination (at [288(f)]);
(d)the finding that the Foxman entities had acted deliberately and in determined contravention of the directions of the council and other regulatory agencies in importing the waste fill material onto the land (at [289(f)]); and
(e)the finding that neither the RAP nor the EMP deals with the existing contamination of the land by lead and other foreign materials (at [289(d)]).
