Introduction 1 New South Wales Sugar Milling Co-operative Limited operates a sugar mill at Broadwater on the Richmond River, in northern New South Wales. The mill was established as long ago as 1884. The village of Broadwater grew around it, mainly to accommodate workers at the mill and on the cane farms in the area. Nowadays the village is less dependent on the mill, whose workers come from further afield. 2 The mill produces cane waste, known as bagasse, which is used to fuel a boiler to generate steam and electricity for use in the plant. On 17 December 2002 Richmond Valley Council granted development consent for a cogeneration facility at the mill, by which biomass material comprising mainly bagasse and cane trash will be combusted in a new boiler to produce steam which will propel a new 30 MW turbine electricity generator. This will be a continuation and extension of the existing steam and power generation activities at the mill, but unlike the present generator it will operate 24 hours a day 365 days a year. During the crushing season the steam generated will be directed to the existing generator at the mill, with excess steam to power a new generator to export electricity to the grid. During the non-crushing season the new generator will direct power to the grid. The proposal includes a stockpile of bagasse on a grazing property known as "Pondarosa" and an overhead conveyer about 1.3 kilometres long between the stockpile and the mill. The proposal will involve a capital investment of about $50 million. 3 Broadwater Action Group Inc now appeals against the grant of development consent, as permitted by s 98 of the Environmental Planning and Assessment Act 1979 ("the EP&A Act"). In separate proceedings (No. 10026 of 2003) Lismore City Council appeals against the failure of Richmond Valley Council to impose conditions upon the consent relating to the upgrading of roads within its area on the opposite side of the river. 4 On 11 September 2003 I determined two questions raised by Broadwater Action Group separately from the other issues, as permitted by Pt 31 r 1 of the Supreme Court Rules 1979 which applies in this Court (see Pt 6 r 1, Land and Environment Court Rules 1996). I held that the development application did not have to be accompanied by a species impact statement and I further held that issue 7 - the fauna and flora impact - was so marginal and insignificant that the development application should not be refused on that ground (Broadwater Action Group Inc v Richmond Valley Council & Anor [2003] NSWLEC 202). 5 During the hearing of the remaining issues the Court took a view of the mill, the site of the bagasse stockpile and the surrounding area in the presence of representatives of the parties. The Court received in evidence a bundle of written statements from local residents and heard evidence in Ballina from a selection of those residents. 6 I have no doubt that the concerns expressed by the residents are genuinely held. They relate mainly to complaints they have about the present and past operation of the mill. Their main concern is that the operation of the mill, which has given rise to the present complaints, will continue and become more extensive and occur for longer periods if the development proceeds. However, for the reasons which follow I have concluded that the proposal will be acceptable if it is subject to conditions which will be imposed so as to limit the impact of the development, not only in relation to the new co-generation plant, but also the existing mill, thereby alleviating the cause of many of the present complaints. Air Quality 7 The applicant claims that there has been inadequate assessment of the effect of the proposal on air quality. Evidence adduced by the applicant consists of Dr N Bofinger's contribution to the joint expert report. Dr G Miller, an expert witness for the second respondent, also contributed to the joint report which he later supplemented with a report in reply. 8 Dr Bofinger's contention is that no assessment of the potential impacts of the proposal upon regional air quality has been undertaken. He states in the joint report that "emissions associated with the proposed development will add to the current level of air pollutants in the region". In particular, he claims that the air quality monitoring program is insufficient to permit the determination of background air quality values, rendering it impossible to ascertain the overall impact of the proposed development on future air quality. The selected monitoring sites, Dr Bofinger claims, are affected by local influences and are not true regional sites. Lastly, he asserts that the Ausplume model adopted by the proponent does not adequately gauge dispersion levels in low wind speed periods or when it is employed close to the stack, particularly during summer. 9 In reply to Dr Bofinger's concerns, Dr Miller states that the air quality assessment for the proposal was conservative, assuming a background PM10 particle concentration level of 30 ug/m3, which, in all likelihood, is higher than the actual readings at Broadwater. To provide some perspective for this analysis, Dr Miller notes that the average annual concentration of PM10 in the Sydney airshed, obviously a relatively congested air space, is at or below this value. 10 Dr Miller claims that Dr Bofinger misunderstands the purpose of the designated monitoring sites, which was to determine approximate background readings for insertion into the model. The sites were not chosen for long term monitoring because the proposed facility is not yet constructed, rendering any results from such a model meaningless. In response to concerns about the Ausplume model, Dr Miller concedes the model is unable to register wind speeds of less than 0.5 m/s. He concludes, however, that this defect is inconsequential in the present circumstances because such low wind speeds would occur most infrequently in the area. 11 Moreover, since the proposed development is integrated development, the Environment Protection Authority ("the EPA") has submitted General Terms of Approval in relation to air quality monitoring requirements. Such requirements include PM10 monitoring for particulate emissions. Despite its alleged inadequacies, this is the current standard measure for control effectiveness and related health effects. Such terms have been incorporated into the conditions of consent, and, very importantly, Dr Miller believes that the proposal is capable of complying with their requirements. 12 Contrary to the applicant's assertions, the fact that the current mill operation may presently be in breach of licence conditions is not relevant to the present question of whether or not development consent for the co-generation proposal should be granted (Kouflidis v City of Salisbury (1982) 49 LGRA 17 at 19). In order to operate the proposed development, having been granted development consent, the applicant must apply to the EPA to obtain either a separate licence for the co-generation plant or a variation of the existing licence for the mill operation which reflects the EPA's requirements for the functioning of the proposed plant (Grace Bros v Willoughby Municipal Council (1980) 44 LGRA 400 at 418). It is only in relation to this further licence application that the proponent's past conduct will become relevant (ss 45(f) and 83, Protection of the Environment Operations Act, 1997). 13 Lastly, despite his concerns, Dr Bofinger concedes later in the joint expert report "that the change from burnt cane to green cane harvesting [a result of the proposal] would lead to a net reduction in the regional particulate burden". He further acknowledges that licence conditions and future air quality monitoring will be undertaken to safeguard residents' health. 14 It seems, therefore, that the impact of the development on regional air quality is likely to have positive overall benefits notwithstanding that the projected emissions from the proposed plant are only estimations. Moreover, the abovementioned mandatory monitoring will control actual emissions once the co-generation plant is operational. Air Quality and Bagassosis 15 Dr M Dawson provided expert evidence for the proponent in relation to the potential for bagassosis spores to be transmitted as a result of the proposal and the potential health effects of human contact with such spores. The applicant adduced no expert evidence in relation to this issue. 16 Mrs A Clarke and Mr R McAllister, residents of Broadwater and objectors to the development proposal, are sceptical about the lack of potential impact of their exposure to bagasse. Their concerns were heightened by an assertion that the sale of bagasse by the mill was "banned" due to health reservations. Dr Dawson, however, confirms that the reason for the withdrawal of bagasse from the market was due to a shortage of fuel for co-generation purposes, rather than any perceived health risk. 17 Further, in response to residents' claims of deaths attributed to bagassosis, Dr Dawson states that bagassosis can only be conclusively identified by post mortem. Claims attributing deaths to bagassosis cannot be proven in the absence of such evidence, evidence which is lacking in these proceedings. Moreover, Dr Dawson states that there has never been a death from bagassosis recorded in Australia. Nor has any case of the disease been confirmed in Australia. In support of this statement, Dr Dawson, in his statement of evidence, refers to research undertaken by the Australian sugar industry and unions. Such analysis concluded that it is very unlikely that the work practices employed in Australian sugar mills would create the conditions in which bagassosis could pose a threat. 18 Dr Dawson also draws upon the opinion of Dr J Lacey, an expert on Extrinsic Allergic Alveolitis, of which bagassosis is a form, who indicated that many years of continuous exposure to airborne spore levels of at least one million per cubic metre would be required for people with pre- existing respiratory problems to possibly develop Extrinsic Allergic Alveolitis. The requisite exposure level for the general healthy population would be greater than one hundred million spores per cubic metre. Such levels, Dr Lacey found, are only possible in confined and enclosed spaces. 19 It is clear that the open stockpile at "Ponderosa" will not create the requisite confined space. The mill's present bagasse stockpile has also been tested and found to be unlikely to contain any spores due to the humidity levels of the bagasse. 20 Further, in light of Dr Lacey's findings, Dr Dawson examined the extensive monitoring of Australia's sugar mills. Such analysis shows that airborne levels measured in and around the bagasse loading and unloading operations, within 10 metres of the source of the spores, were only in the tens of millions per cubic metre range. At 100 metres downwind of the source, the airborne level had dropped below one million per cubic metre. 21 Given these conclusions and in the absence of any authoritative evidence to the contrary from the applicant, it must be concluded that the conditions in all likelihood will not exist to enable bagassosis to pose a threat to the residents of Broadwater. It follows, then, that consent to the proposal ought not be withheld on this ground. Ground Water 22 The evidence of the applicant's expert, Mr J Ross, is contained in the joint expert report on ground water. Mr Ross agrees for the most part with Dr F Carosone, the expert witness for the second respondent. Mr Ross only makes some additional requests in relation to the management plan. 23 Dr Carosone, as set out in his contribution to the joint expert report and his report in reply, believes that the proposed conditions of consent and General Terms of Approval presently incorporate Mr Ross' requirements, save that for the provision of shallow and deep monitoring bores. So as to accommodate this stipulation, Dr Carosone states that an amended Groundwater Management Plan will be prepared. The proponent has proposed a draft condition to this effect which will meet Mr Ross' concerns. 24 Given this general agreement and the concessions made by the second respondent, the Court is confident that the impact of the proposed co-generation plant upon ground water is insufficient to warrant a refusal of development consent. Traffic 25 The applicant's concerns about traffic are prompted by the assumption that there will be an increase of 157,500 truck movements during a 25 week crush period in 2004, increasing to 175,000 truck movements by 2010. This is estimated to be 900 extra truck movements per day. Such an upsurge, it is claimed, will take place in the village centre, creating intolerable environmental and health impacts on the residents and the amenity of the village of Broadwater. The facts, however, show that these assumptions are erroneous and demonstrate a misunderstanding of the impact. 26 It is also claimed by the applicant that an increase in the number of heavy vehicles using local access roads (and an increase in their capacity) will heighten the risk of accidents involving pedestrians on the Pacific Highway at Broadwater. This is further exacerbated by trucks using the Broadwater Bridge, across which there is no pedestrian walkway. 27 Lastly, the applicant claims that inadequate consideration has been given to the entrance and exit to the site, which is located on the Pacific Highway within 50 metres of businesses and residences. 28 However, contrary to the residents' impressions, the assessment of the proposal's impact on traffic in the EIS shows that in 2004 the proposal will create an increase of 168 truck movements per day in the crush season, and only an increase of 12 truck movements per day in the non-crush time. In 2010, the proposal is estimated to increase traffic by 199 truck movements per day during the crush season and 12 in the non-crush period. This is demonstrated by the graphs of "Highway Mill Traffic Crush Season" and "Highway Mill Traffic Annual Average" in the EIS. 29 Further, these traffic figures do not account for the reduction in truck movements to and from "Ponderosa" due to the construction of the proposed conveyor. This will especially benefit the residents living along Rifle Range Rd and near the route connecting the co-generation plant and "Ponderosa". The conveyor belt will also increase pedestrian safety along that portion of the Pacific Highway presently used by such trucks, as will the relocation of the entrance to the mill to a position further away from the village. Lastly, the proponent will be upgrading the Pacific Highway, not only for the purpose of the proposed co-generation plant, but also for the existing mill. 30 It follows, then, that consent for the proposal would be refused on the ground of its potential impact upon elements associated with traffic.
