Council documentation after 10 December 1993
196 The trial judge stated that the Council's "course of action … based on restricting development because .. land was subject to the Risk Reduction Zone" was "also adopted in relation to subsequent applications for development …". The development applications referred to all related to land in the vicinity of the ICI complex. Jazabas submitted that later Council documentation supported its primary case that the policy which it ascribed to the Council existed in the material, earlier period.
197 Some of the Council's documents for the period after 10 December 1993 have already been discussed. The first of the "subsequent applications" referred to by the trial judge related to the rezoning of the "Davis Gelatine site" at 28 Spring Street Botany from Industrial 4(a1) to Residential 2(b). That application was not made until November 1994, approximately a year after the material s 149 certificate. There is nothing in any document prior to 6 June 1996 when Jazabas' was notified that its medium-density residential development application had been approved to strengthen its case that the Council had a policy between November 1993 and January 1994 to restrict development, or residential development, on land in the RR zone by reason of the risks identified in the RAS.
198 Early in 1996, the Council was engaged in litigation in the Land and Environment Court with Johnfletcher International, which had applied for development approval for a "container terminal and general storage facility" on approximately 5.4 hectares of land at the eastern end of Swinbourne Street, Botany. The development proposed included the provision of office space to accommodate approximately 50 employees and a caretaker's dwelling. Both the offices and the caretaker's dwelling would be within about 50 metres from the boundary of the ICI complex.
199 On 25 March 1996, Mr G.W. Smith, a director of Design Collaborative Pty Ltd, which was representing the Council in its Land and Environment Court dispute with Johnfletcher International, wrote to the Hazards Assessments branch of the Department of Urban Affairs and Planning. Mr Smith's letter said:
"We act for the Council for the City of Botany in this matter which is part heard by the Court. We seek your advice/assistance in relation to aspects of the proposed development which, we are told from some sources, breaches existing policy/guidelines in relation to development in the vicinity of the ICI complex.
…
Officers of our client Council claim that they are not aware of any restrictions on the establishment of dwellings close to the ICI complex. Others have claimed that a dwelling in this position would be exposed to abnormal hazards and could prejudice operations in the ICI complex. In particular, it is asserted that the level of noise from flaring and other operations at the ICI complex would far exceed what is acceptable in a dwelling as might be the noise from operations along the goods railway line. In addition, there is the issue of hazard from the petro/chemical complex where large storage tanks for aromatics and petroleum feed stock would be within 70 to 80 metres of the proposed dwelling.
Could you please advise us of any restrictions or precautions that ought to be taken (e.g. that might be included by way of conditions on any approval of the proposed development), which might be pertinent to such a proposed development?
The hearing is set down to continue in the Court on 23 April. We would appreciate receiving your advice as soon as possible so that we can - if necessary - draft appropriate conditions for inclusion in the draft conditions of consent which must be tendered to the Court on 23 April."
200 As earlier noted, Jazabas' application for medium-density residential development on the land was lodged with the Council on 1 April 1996 and favourably reported on 15 April 1996. There is nothing in that report, or any of the Council documents relating to Jazabas' development application, which supports Jazabas' argument that it was Council policy to restrict residential development in the RR zone by reason of the risks identified in the RAS.
201 On 22 April 1996, the Department of Urban Affairs and Planning replied to the letter from Mr Smith of Design Collaborative Pty Ltd in relation to the development application which had been made by Johnfletcher International. The Department's letter, which was signed on behalf of Mr Sam Haddad, an Assistant Director-General, said:
" ….
The Department has no specific knowledge of the details of the above development or Council's assessment. The following advice relates solely to hazards and does not consider other environmental issues, such as offensiveness to air pollution, noise or visual amenity or other planning issues.
The Department's broad policy in relation to development in the vicinity of the ICI complex is that each should be assessed on its merit."
202 After reference to the RAS and the provisions which it contained in relation to land in the RR zone, the letter from the Department continued:
"The fatality risk criteria, in conjunction with the injury, irritation and biophysical risk criteria should be used by Council as appropriate, to assess the merits of a proposed development within a permissible zone.
The study of the Botany/Randwick industrial area was undertaken to assist with land use safety planning in the vicinity of the Industrial Complex and took the above criteria into account.
The proposed caretaker's residence is inside the 1 x 106 per year fatality risk criteria contour within which new permanent residential occupancy may not be appropriate."
203 On 24 April 1996, Ms Cathy McMahon, a senior town planner employed by the Council sent a memorandum to three other Council town planners. Ms McMahon attached a copy of the letter from the Department of Urban Affairs and Planning to Design Collaborative Pty Ltd, and said:
"A copy of Figure 5 from the Risk Assessment Study which is mentioned in the Department's response is attached. The map is somewhat hard to read and I have requested another copy of the [RAS] from the Department."
204 Nothing further occurred before the Council approved Jazabas' medium-density residential development application on 4 June 1996 and notified Jazabas of the approval on 6 June.
205 On 2 July 1996, Mr Ian Dencker, the Council's Manager - Environmental Planning wrote to the Department of Urban Affairs and Planning in connection with a development application which the Council had received for a tourist depot at 21-23 Green Street Botany. The proposed development involved the provision of four bedrooms to be used for driver "sleeper-overs" on an intermittent basis and a caretaker's apartment. Mr Denker's letter said:
"In view of restrictions to further intensification of new residential developments in the vicinity of the ICI complex and Port Botany as recommended in the [RAS], Council seeks your advice on the following:
1. Whether or not the intermittent use of drivers' accommodation is permissible in the subject site.
2. Whether or not the use of a caretaker's flat for residential purposes is permissible in the subject site.
.."
206 The Department wrote back on 6 September 1996 as follows:
"It is advised that the construction of a caretakers residence and intermittent driver accommodation as part of the proposed development is located towards the edge of the "risk reduction" zone as identified in the 1985 Risk Assessment Study for the Botany/Randwick Industrial Complex and Port Botany. As such the accommodation is unlikely to be subject to an intolerable risk level based on the 1985 study.
Further, as the proposed development represents a very small change in the number of people, societal risk implications are likely to be minimal. Accordingly the Department would not consider that the proposals would be unacceptable based on risk grounds alone.
In regard to the question of the permissibility of development in the area. This is a matter for the Council to determine and the Department offers no comment on the issue."
207 In the meantime, officers of the Council and the Department of Urban Affairs and Planning had a meeting on 25 July 1996 in relation to "hazard issues". On 30 July Mr Dencker wrote to Mr Haddad at the Department about that meeting. The material part of his letter provided:
" RE: HAZARD ISSUES - BOTANY BAY CITY COUNCIL
Thank you for organising the meeting held at the offices of the Department of Urban Affairs and Planning on 25th July, 1996, where various hazard issues of relevance to this Council were discussed.
Council would like to confirm with you the following issues raised at the meeting:
1. The Department of Urban Affairs and Planning is in the process of beginning a new hazard analysis to update the hazard contour lines for the Banksmeadow area. In this regard, the Department will provide Council with a work program for the analysis by about mid-August, 1996. The Department would welcome Council's involvement in the analysis, so that Council's concerns can be given due consideration. In the interim, Council may also present to the Department the proposed new residential areas that Council is proposing under its Residential Strategy seeking the Department's advice on the hazard implications for these proposed areas.
2. New hazard contours for Port Botany would be made available to Council by about mid-August, 1996.
3. The Department of Urban Affairs and Planning would be willing to provide advice to Council on hazard issues if, and when, requested by Council. Industrialists seeking advice from the Department on matters within Council's jurisdiction would be advised, as a matter of course, to contact Botany Bay City Council directly.
…"
208 The meeting between the Council and Department officers in relation to "hazard issues" on 25 July 1996 marked a turning point. Thereafter, in accordance with paragraph 3 in Mr Dencker's letter dated 30 July 1996 to the Department, the Council sought departmental advice in relation to residential development applications for land in the RR zone and generally decided those applications in accordance with that advice. Mr Haddad was opposed to residential development in the RR zone by reason of the risks identified in the RAS.
209 Late in 1996 or early in 1997, an application was made for development approval for the conversion of an existing dwelling at 22 Beauchamp Road Hillsdale into an attached dual occupancy (the "22 Beauchamp Road application").
210 A little later, another development application sought "residential subdivision of a single lot into two premises at 36 Denison Street, Hillsdale" (the "36 Denison Street application").
211 The Council sought advice from the Department in relation to the 22 Beauchamp Road application on 21 January 1997 and in relation to the 36 Dension Street application on 22 April 1997.
212 The Department gave the Council the same advice in relation to both applications, namely: [9]
"The subject site is in close proximity to the ICI existing industrial complex. Irrespective of the quantitative nature of the risk contours, the intensification of residential development at this location, notwithstanding minor, is inconsistent with good land use safety planning. Intensification of residential development by way of subdivision at this location is also inconsistent with broad environmental amenity.
By way of general comments, whilst continuous efforts must be maintained and strengthened to reduce environmental risk and pollution from existing industrial operations in the area, it is as strategically important not to increase the number of people exposed to the potential effects of such operations."
213 The Council's Manager - Environmental Planning recommended refusal of the 22 Beauchamp Road application and the 36 Dension Street application for the same reasons, namely:
"1. Pursuant to Section 90(1)(g) of the Environmental Planning and Assessment act, 1979, the land to which that Development Application relates is unsuitable for that development by reason of its being, or likely to be subject to any other risk.
2. Pursuant to Section 90(1)(n) of the Environmental Planning and Assessment Act, 1979, the representations made by the Department of Urban Affairs and Planning.
3. Pursuant to Section 90(1)(q) and (r) of the Environmental Planning and Assessment Act, 1979, the circumstances of the case and the public interest."
214 On 25 June 1997, the Council refused the 36 Denison Street application [10] for the reasons recommended by the Manager - Environmental Planning. An appeal to the Land and Environment Court was subsequently dismissed.
215 On 2 July 1997, a decision on the 22 Beauchamp Rod application was deferred after the applicant addressed the Council's Development Committee. Subsequently, the application was refused for the reasons recommended by the Manager - Environmental Planning. An appeal to the Land and Environment Court was dismissed.
216 The report of the Council's Manager - Environmental Planning in relation to the 36 Denison Street application, which was dated 4 June 1997, also included the following recommendation:
"It is further RECOMMENDED that senior Council officers, as a matter of urgency, seek a meeting with the Assistant Director-General, Mr. Sam Haddad, as to the wider risk implications associated with the operation of the ICI industrial complex and, specifically, the ICI chlorine plant to land use in the locality."
217 Jazabas' application for building approval was lodged with the Council on 20 October 1997.
218 On 31 October 1997, Mr R.J Dowsett, the Council's Manager - Building Control and Principal Building Surveyor, wrote to the Department of Urban Affairs and Planning as follows:
"The Council has before it, a Building Application to erect a cluster housing development on vacant land at Hillsdale, and known as 2 - 10 Nilson Avenue Hillsdale, in Lot 1, DP224496.
Consent exists under the Environmental Planning and Assessment Act 1979, for this development.
However, between the granting of Consent by Council on the 6th June 1996, and now, the implications of hazard lines have arisen and the Departments advice is sought as to whether or not the site is within the area contained with the Botany hazard line.
…"
219 On 7 November 1997, the Department responded to Mr Dowsett's letter of 31 October 1997 as follows:
"..
I refer to your letter dated 31 October 1997 requesting confirmation of the abovementioned sites location in relation to hazards work completed in 1985.
The Department confirms that the site located at 2-10 Nilson Avenue Hillsdale is within the general risk reduction zone identified in figure 5 of the Department's A Risk Assessment Study for the Botany/Randwick Industrial Complex and Port Botany (1985).
…"
220 Mr Dowset reported to the Council on 10 November 1997. His report recommended that Jazabas' "building application be deferred and other measures placed entrain to address the issue of hazard". The "other measures" proposed would have required ICI to cease conducting activities which were a "source of potential hazard" to the land and other sites. The report contained the following statements:
"However it has come to the notice of the Manager - Planning and Environment that the site is within the boundaries of a risk reduction zone and given this situation, the knowledge of which surfaced after the granting of Consent, that the Building Application should not be determined or if determined, refused by reason of potential hazard implications.
It is also the position of the Manager, that had this information been known when the Development Application was lodged, the application would have been recommended to Council for refusal.
There is perhaps no need to dwell on what has happened, but the liability that is now likely to arise cannot be understated.
The likely hazard to the site apparently arises from the Chlorine Plant at ICI, although the availability of information pinpointing the potential source or sources of identified hazards and the subsequent consequences thereof, remains with Department of Urban Affairs and Planning."
221 A more senior Council officer required Mr Dowsett's assertion that the knowledge that the land was in the RRZ had "surfaced" after Jazabas' medium-density residential development application had been granted to be checked. That officer expressed the opinion that the Council would not be liable for granting Jazabas' development approval "[p]roviding there is absolute certainty knowledge of the effect of the 'risk reduction' zone on property 2-10 Nilson Avenue WAS NOT KNOWN by Council officers PRIOR TO granting of development consent…". There after, the Council's concern with its potential liability increasingly attracted its attention.
222 The Council's change of attitude became known to Jazabas at about that time. Another s 149 certificate was obtained in connection with Jazabas' borrowing to finance its medium-density residential development of the land. This time, the Council gave a "yes' answer in relation to item 10 and referred to the RAS.
223 Mr Haigh telephoned Mr Dowsett after the new s 149 certificate was issued. The trial judge said:
"[Mr Haigh] said that Mr Dowsett told him that the Council had become aware of a problem relating to [Jazabas'] Building Application "a couple of weeks ago and I had avoided talking to you in the hope that the discussions I am currently having with the Department may resolve the matter". Mr Dowsett said the problem related to the proximity of the land to the ICI chlorine plant; that an RAS was done in 1985 by the Department of Urban Affairs and Planning, …; but that the Council "had not seen a copy of the report but was aware of its existence". Mr Haigh's evidence was not sought to be contradicted, but obviously what Mr Dowsett told him about the Council's not having seen the RAS was not correct. It was clearly aware of it from the time of its publication in 1985."
224 On 23 December 1997, Jazabas appealed to the Land and Environment Court against the Council's deemed refusal of Jazabas' application for building approval.
225 On 6 January 1998, a solicitor then appearing for the Council told Mr Haigh that he wanted Jazabas' Land and Environment Court appeal stood over for 21 days to give him the opportunity to seek to resolve it. Shortly thereafter, Mr Dowsett informed Mr Haigh that Jazabas' application for building approval should go to a meeting of the Council towards the end of February 1998 "as it is recommended for approval".
226 Decisions by Land and Environment Court Assessors in late February or early March 1998 dismissed appeals against the Council's refusal of the 22 Beauchamp Road application and the 36 Denison Street application.
227 Evidence based on the RAS was given on the Council's behalf in those Land and Environment Court proceedings by Mr Haddad. In addition, Mr Haddad wrote to the Council on 16 February 1998 in relation to Jazabas' proposed residential development in the following terms:
"Re: 2-10 Nilson Avenue Hillsdale - Proposed Cluster housing Development
I refer to your letter dated 30 January and confirm verbal advice furnished by Derek Mullins with respect to the matters raised.
There appears to be a misunderstanding as to the nature of the risk reduction zone identified in Figure 5 of the Department's, " A Risk Assessment Study for the Botany/Randwick Industrial Complex (1985)". Your letter states "The Council notes that the general risk reduction zone.. was founded on the hazards of fire and explosion." This assumption is incorrect. The generalised risk reduction zone should not be equated to a particular criterion level but is based on the identification of an area in which land use safety controls need to be focussed. For this reason, it is invalid to make a comparison between that zone and the Olefines 2 Fire and explosion Individual Risk (Figure A3.10, appended to your letter).
The subject site is in close proximity to the Orica (Formerly ICI) industrial complex and specifically to the chlorine plant and associated operations. Irrespective of the quantitative nature of risk contours, the intensification of residential developments at this location, notwithstanding minor , is inconsistent with good land use safety planning. Intensification of residential developments by way of subdivision at this location is also inconsistent with broad environmental amenity.
I trust the above is of assistance to Council, as consent authority, in tis future considerations."
228 In March 1998, Mr Dowsett informed Mr Haigh that the Council would be defending Jazabas' Land and Environment Court appeal.
229 The Amended Statement of Issues in the Jazabas' Land and Environment Court appeal were as follows:
"1. Given the location of the subject property within the Risk Reduction Zone established by the 1985 Risk Assessment Study for the Botany/Randwick Industrial Complex and Port Botany undertaken by the then Department of Environment and Planning in 1985, and the proximity of the subject property to the Orica Australia Pty Limited (formerly ICI Australia Limited) Petrochemical Complex and in particular to the Chlorine Manufacturing Plant within that Complex:
(a) the building plans are unsatisfactory in that:
(i) they do not demonstrate a sufficiency to protect the inhabitants of the proposed buildings and their curtilages from risk of death or injury in the event of a substantial release of a toxic gas such as chlorine from the Orica Australia Pty Limited Plant;
(ii) they do not include physical means to warn occupants or visitors of contamination events from the sources described in the 1985 Risk Assessment Study for the Botany/Randwick Industrial Complex and Port Botany.
(b) The deficiencies referred to in (a) above are incapable of being remedied in that there are no reasonable or practical measures available that could make the proposed buildings and their curtilages safe for occupants in the event of a substantial release of toxic chlorine gas from the Orica Australia Pty Limited Chlorine Plant."
230 Mr Dowsett and Mr Haddad gave evidence on behalf of the Council in support of the Amended Statement of Issues, in which they relied on the RAS and the Department of Urban Affairs and Planning's opposition to residential development on the land based on the RAS.
231 On 23 April 1998, a Land and Environment Court Assessor dismissed Jazabas' appeal against the Council's deemed refusal of Jazabas' application for building approval. The Assessor decided that the evidence established the land "..unsuited for further residential intensification on hazard grounds".
232 By that time, the Council was consistently relying on the risks identified by the RAS to refuse residential development applications in the RR zone and was simultaneously concerned about its potential libaility.
233 On 25 May 1998, the Mayor wrote a memorandum to the Council General Manager in relation to another property [11] in which he stated:
"This building application, as I understand it, is for a lot of a subdivision which the council approved in August, 1995.
The reality of the situation is that if the Risk Reduction Study (sic) not have permitted an intensification of the relative use, then the Council should not have approved the subdivision in 1995. It is, in my view, not an intensification of the use to build a house on land subdivided for that purpose, it is an intensification of residential use to allow the subdivision in the first place.
In my view, having allowed the subdivision in the first place, the Council would be liable for damages even allowing for the lack of moral in revising the building application.
On the other hand, if the situation is so dangerous that it would be responsible to approve the application, then that is a different situation and if that be the case, then a decision needs to be made as to others in the locality requiring relocation."
234 Reports by Mr Dowsett in about May 1998 again asserted that applications which had earlier been approved would have been recommended for refusal if the Council had known of the RAS when the applications were approved, because to do otherwise "… would have been inconsistent with the objectives of the [RAS] to curtail further residential development in the [RR zone]." On the evidence, Mr Dowsett's assertions were based on assumption.
235 In one report from Mr Dowsett to the General Manager, [12] he said:
"…
It was not until April 1996 that Council became aware of the Studies practical impact. However, notwithstanding the knowledge of such, Consents were subsequently granted for … (Lot No 3) and the development of land at 2 - 10 Nilson Avenue Hillsdale.
The land 2 - 10 Nilson Avenue … exists in the defined hazard area and Council was left with no alternative but to address the issue of risk at the Building Application stage, whereas the more appropriate place would have been at Development Application stage.
The issue of hazard was related to the "healthiness of the building' and whilst it was acknowledged that this reason involved a great deal of latitude on Council part, as to suitability of this matter for consideration, the applicant to the Appeal did not question the matter of power.
It was the view of Senior Counsel that had the applicant challenged the basis for refusal then the Assessor would have had not (sic) alternative but to refer the matter to the Duty Judge who in turn, would have dismissed the Appeal.
…
As alluded to in a recent report to the Development Committee council is likely to face a civil claim in relation to the granting of Development consent to 2 - 10 Nilson Avenue Hillsdale.
Even with the recommendation to refuse the subject application, the Council may incur liability as like 2 - 10 Nilson Avenue Hillsdale, the land cannot be developed and is sterile to development of the kind the zoning permits. On the other hand, to grant approval, there remains the potential for occupants to be subject to illness or injury through accident, foul play or the like that may give rise to a toxic release from the adjoining industrial premises.
Either way Council is exposed to liability and it is a question of taking the more appropriate course which in this instance, is refusal of the Building Application."
236 The Council's Director-Technical Services adopted a different attitude in a report which he wrote to the General Manager on the following day 27 May 1998. "[C]ommonsense" led him to the conclusion that "… approval should be granted to the development of the last underdeveloped lot" in the subdivision at 54 Denison Street Hillsdale. Later, his report stated:
"…
As for property 2-10 Nilson Avenue, Council is now in a position of some difficulty, given the current rejection of an application for building consent by the Land & Environment Court.
I am of the opinion, if a claim for substantial damages is received in respect of the granting of development consent and rejection of building consent, it may be preferable to again revisit the development, through a new application, with a view to granting building consent given the rationale set out in relation to property 54 Dension Street, Hillsdale.
I appreciate the quasi-legal view adopted by Mr Dowsett is a course to which he is, and should be, restricted but I am strongly of the opinion a somewhat wider approach might be taken by the Council, given the relevant circumstances applying to date and future liability that may be occasioned.
I would appreciate the opportunity for further discussion on this matter prior to reference to the Mayor and/or a relevant Committee."
