128 R.A.T.W.I.S.E tabled one letter from a resident of Colemans Road who alleged he had suffered adverse health effects from an "awful smell" from the Lyndhurst facility last year. It is likely that the incident referred to arose from contaminated soil from a gasworks. We address this later in the section of our determination dealing with air quality. We are satisfied that whilst there have been some incidents of odour giving rise to complaints, there are no persistent problems or consistent levels of complaint about odour or any other adverse amenity impacts. We are satisfied that when there have been complaints, measures have been instituted to address them.
129 We do not consider that in this location, which is a rural/industrial environment, the occasional odour incident is a reason for refusing to amend the permits or for saying that the Lyndhurst facility should no longer accept prescribed industrial waste. The site also operates as a landfill for putrescible waste and this may also give rise to the occasional odour problem. Occasionally odour may also originate from the market gardening activities in the area.
130 One of the reasons why a rural/industrial area such as Lyndhurst is a good location for this type of facility is the buffer distances that exist between it and residentially zoned land. EPA regulations and licences control emissions. However, even with good pollution control technology and practice, there may still be unintended emissions which must be anticipated and allowed for. The role of buffer distances is to allow unintended or accidental emissions to dissipate without adverse impacts on sensitive land uses. We are satisfied that the Lyndhurst facility meets EPA requirements regarding air emissions. We consider that the 1 kilometre buffer distance between the facility and the nearest residentially zoned land at Lynbrook Estate is adequate and that experience with the operation of the Lyndhurst facility over the past 16 years has demonstrated this to be so. The Willow Lodge Mobile Home Village, which is located approximately 1.5 kilometres to the west, is not in a residential zone but in a Green Wedge Zone. Nevertheless, it is a concentration of residential use but, as with the Lynbrook Estate, we consider that the buffer distance is adequate.[33]
131 We acknowledge there are some dwellings that are in closer proximity to the Lyndhurst facility. However, they are located in a Rural Zone and residential use is not a purpose of this zone. The amenity of dwellings in a Rural Zone may be adversely affected by activities within the zone and cannot be expected to be the same as in a residential zone where the primary purpose is residential use. When the surrounding land is rezoned to the Industrial 1 Zone, dwelling will become a prohibited use. It can be expected that existing dwellings will phase out over time with transition from rural use to industrial use. We note that with the exception of the letter tabled by R.A.T.W.I.S.E referred to earlier, there were no submissions from the local residents. Indeed, there were letters tabled by SITA from residents of Colemans Road stating that neither the Greater Dandenong City Council or R.A.T.W.I.S.E represented their interests.
132 We have therefore concluded that there will be no adverse amenity effect if the permits are amended.
133 Amendment C87 to the Greater Dandenong Planning Scheme does not propose to include the subject site in the Industrial 1 Zone but rather leaves it in the Rural Zone. This is because future use of the land after it ceases use as a landfill will be for open space purposes as the land will not be suitable for industrial use. Pumping of leachate will be required for many years. However, the site's strategic future as open space is not its dominant value in a planning context. Its greatest significance in a strategic planning context is its current use as a landfill, which includes a landfill licensed by the EPA to accept prescribed industrial waste. The need for such facility to serve Victoria has already been addressed. The life of the Lyndhurst facility is not constrained in the way that the Tullamarine facility is. We therefore consider that there are no planning issues relating to the future use of this site that will be counter to amendment of the permits.
134 Finally, we consider that amending the permits is supported by planning policy. Local planning policy in the Greater Dandenong Planning Scheme acknowledges the significance of the Lyndhurst facility, although not specifically as a facility accepting prescribed industrial waste. The objectives of planning in Victoria, specifically section 4(1)(e) of the Planning and Environment Act 1987, and the State Planning Policy Framework (Clause 11.03-4) promote the protection and efficient use of public utilities and existing urban infrastructure.
135 In our view, the Lyndhurst facility must be regarded as an important item of urban infrastructure in terms of waste management of State significance. It has been designed and engineered to accept prescribed industrial waste for disposal. In terms of an efficient use of resources and infrastructure it is desirable that it be permitted to be used for the purpose for which it has been designed and built. It is equally desirable that a landfill that can accept prescribed industrial waste be co-located with an existing landfill which accepts putrescible waste, if possible. Each type of landfill will require buffer distances which adequately separate it from sensitive land uses. Such sites are not readily available. Thus it is a far more efficient use of land if they can be co-located rather than requiring two separate facilities. Equally, it is more desirable if an existing facility can be used for such purpose rather than establishing a new facility, which experience has demonstrated is extremely difficult.
136 In conclusion, there was no evidence that the Lyndhurst facility is not a safe facility, that its use for disposal of prescribed industrial waste causes any unacceptable effect on amenity or that there will be any change to amenity or impact on the environment as a consequence of amending the permits. Rather, we consider that the location; the zoning of the subject site and surrounding areas, existing land use; and buffer distances make this a suitable location for a landfill for prescribed industrial waste. There are no planning considerations which in our view would militate against amendment of the permits.
