Issue 2: Is the draft ANEF precluded from being able to be endorsed by Airservices because of the Airports Act?
52 Village asserted that if Airservices endorses the draft ANEF it will be acting in a manner approved by the Minister within the meaning of the definition of the term 'Australian Noise Exposure Forecasts' in s 5 of the Airports Act. Village asserted that this result followed because Airservices had the function of endorsing ANEFs for the purposes of the Air Services Act under the s 16 direction given to it in May 1999.
53 However this argument fails to address the source of the power or function which Airservices presently is able to exercise or perform and whether it answers the definition in the Airports Act. The source of Airservices' power or function to endorse an ANEF is the direction of the Minister under s 16 of the Air Services Act. That direction was given in1999, well before the May 2007 amendments to the Airports Act which made provision for the Minister to approve a manner for endorsing an ANEF under that Act. Both the Air Services Act and the Airports Act are silent about Airservices having any role under the Airports Act in relation to ANEFs.
54 In addition, Village's argument is not supported by the legislative history of the Airports Act, in light of the 2007 amendments. Those amendments inserted for the first time in the Airports Act the defined term Australian Noise Exposure Forecast as meaning a forecast '… endorsed in the manner approved by the Minister'. At the time of the hearing, no manner for the endorsement of such a forecast under the Airports Act had been approved by the Minister. It follows that the Minister had yet to exercise his power, created by the 2007 amendments, to provide any mechanism for the endorsement of an ANEF under and for purposes of the Airports Act.
55 Airservices indicated on 18 June 2007 that the draft ANEF was in a suitable form for its endorsement. This indication can only have been a reference to an endorsement made pursuant to the function conferred on Airservices by the Minister's 1999 direction under s 16(1) of the Air Services Act. Such an endorsement is not one which meets the definition of an ANEF approved by the Minister for the purposes of the Airports Act. This is because he has not yet approved any manner for endorsing an ANEF under that Act.
56 If Airservices were to endorse the current draft ANEF, such an endorsement would not enliven any obligation of the airport lessee under s 78(2A) of the Airports Act to prepare a new draft master plan. This is because, once again, no manner approved by the Minister for the endorsement of ANEFs for the purposes of the Airports Act has yet come into existence. Unless and until the Minister exercises his power to approve a manner for endorsement of ANEFs for the purposes of the Airports Act, the new amendments to that Act, including s 78(2A), will not operate on ANEFs endorsed by Airservices were it merely to act under the s 16 direction given under the Air Services Act.
57 Village also argued that an ANEF could not be made which forecasts noise exposures for a period in excess of the 20 year planning period provided by s 72 of the Airports Act. This is, it says, because s 72 provides that a draft or final master plan 'must relate to a period of 20 years', called the 'planning period', and s 73 requires an assumption to be made for the purposes of a draft or final master plan for an airport, that the then airport lessee will continue to hold the lease for the duration of the planning period of the plan. Village noted that s 78(2A) of the Airports Act created an obligation for an airport lessee to give the Minister a new draft master plan when a more recent ANEF was endorsed in a manner approved by that Minister. Village contended that because s 72 of the Airports Act was in mandatory terms, any new draft master plan for which s 78(2A) provided could not relate to a period longer than the 20 year planning period in s 72.
58 However, s 71(4)(c) was also inserted into the Airports Act by the 2007 amendments. It now provides a power to make a regulation which authorises a forecast, including an ANEF under s 71(2)(d), that relates to a longer period than the 20 year planning period. Both the explanatory memorandum and a letter dated 16 July 2007 from the deputy secretary of the Department of Transport and Regional Services to the general manager of Queanbeyan City Council contemplate that, in fact, regulations will be made under s 71(4)(c) to permit forecasts in ANEFs to be specified in a master plan for a period greater than the 20 year planning period.
59 I am of opinion that the proper construction of the Airports Act does not support a requirement that the ANEF specified in a draft or final master plan must be limited to the planning period of 20 years. The possibility of a longer period to which a forecast may relate in respect of matters which must be specified in a master plan is now expressly contemplated by the power to make regulations under s 71(4)(c) to that end.
60 Moreover, the construction of s 71(2) must accommodate the fact that the Parliament intended to provide a means of regulating the development and future use of airports which are major infrastructure assets. The section operates in respect of elements of master plans, some of which will endure longer than 20 years even though the plan itself relates to that limit as its planning period. Thus, s 71(2)(a) requires a draft or final master plan to specify the airport lessee's 'development objectives for the airport'. And, s 71(2)(c) requires an airport lessee to specify its intentions for land use and related development of the airport site. Those requirements necessarily involve the existing airport as well as matters such as the maintenance, removal, amelioration or erection of fixtures, including runways and buildings, which are capable of enduring beyond the 20 year planning period.
61 If Village's argument were correct, the only planning concepts available for consideration in a master plan under the Airports Act would bethose which in express terms are for no more than 20 years.
62 The Parliament could not have intended that an ANEF could not go beyond 20 years in a draft or final master plan with the consequence that other development, surrounding an airport in a major city in Australia, could occur which would prevent the airport's future development. If that were correct, a new site would later be required on which to build another airport when the needs of the city for aircraft movements exceeded the 20 year projection. That would create further environmental impacts from noise in two locations, rather one, for the one city.
63 I am of opinion that on its proper construction the Airports Act does not prevent an ANEF being made for a period beyond the planning period provided that it relates to that planning period. Indeed, it can hardly have been the intention of the Parliament in enacting the Airports Act, as amended, to have stultified the future growth potential of an airport in the way contended for by Village. The consequence of Village's argument, that an ANEF cannot extend beyond 20 years, absent a regulation under s 71(4), is that third parties would be able to engage in development or uses of land around an airport which created a planning conflict between the user of the airport and the surrounding development at a time over 20 years away, that prevented the future expansion of use of the existing capacity of the airport.
64 The process of approving a use of land and providing a planning regime for land necessarily involves consequences in the immediate short term, as well as in the longer term. Any major public or private infrastructure development will have planning impacts which are of indefinite duration. Once built, the development will affect the surrounding environment by the manner, nature and extent of its user. But its effect may also extend to the potential for further development in the future not only of that site but of surrounding property. A development consent to permit a large factory, for example, will create development impacts including those from emissions, noise, traffic, supporting infrastructure (such as shops, food outlets and transport for workers) and the appropriateness of planning controls for nearby land.
65 One significant purpose of Div 3 of Pt 5 of the Airports Act is to enable proper and public assessments to be made of draft and final master plans for major Australian airports on a regular, at least five-yearly, basis. But a major airport of the kind regulated under s 68 of the Airports Act is not merely a development with a fixed life of 20 years. Rather, it forms a vital and necessary part of the transport infrastructure not only of the city in which it is located but also of the nation. A master plan is contemplated by s 71 of the Airports Act to relate to a planning period of 20 years. But the development, being the airport itself, has planning impact for an indefinite duration. The mere requirement in s 72 that a master plan relate to a period of 20 years, does not preclude the plan also referring to a longer period, provided that it otherwise satisfies the obligation specifically to address the matters in s 71(2) in a manner which relates to the planning period of 20 years. It would be absurd to conclude that because a new runway will last and be used for more than 20 years, a draft master plan would be invalid if it considered the runway's use as a long-term fixture beyond the 20 year planning period.
66 Thus, s 71(2)(e) requires draft and final master plans to include the airport lessee's plans for managing aircraft noise intrusion in areas forecast to be subject to exposure above 30 ANEF levels. These plans are required to be developed following consultation by the airport lessee with airline users and local government bodies in the vicinity of the airport. And the airport lessee is also required to develop those plans having regard to the Standard (cf: s 71(8) of the Airport Act). As explained above, the Standard recognises that one type of ANEF is an ultimate capacity ANEF. This can be a planning tool of significance in a master plan. An ultimate capacity ANEF can be both current (ie at the present time or at a time within the s 72 planning period) and prospective (ie beyond 20 years hence). It can be current because it measures what user the airport is actually able to achieve in its present state, if it were ever required to be used to that level. It is prospective in the sense that the forecast time at which the airport's normal operations are expected to be at ultimate capacity may be years into the future. But in each sense, an ultimate capacity ANEF will relate to the 20 year planning period because any long term development of the airport and the surrounding vicinity must have regard to the impact of its operations at its ultimate capacity, whenever the airport is used at that level.
67 The purpose of ss 71(4), 72 and 73 requiring a master plan to relate to planning period of 20 years, or such other period as is prescribed, is to ensure that detailed analyses will be undertaken for that identified period. The power in s 71(4) to prescribe a longer period to which elements of the master plan may relate permits the period on which the plan focuses to be increased. But a master plan which in fact relates to the 20 year or greater or other planning period provided in s 72 or by a regulation under s 71(4) of the Airports Act, is not prohibited by any provision of that Act from, in addition, referring to another period which is longer. Suppose an airport lessee specified in a draft master plan under s 71(2)(a) a development objective to construct a new runway in the five year period which the draft plan was to cover. If Village's argument were correct, the airport lessee could not lawfully analyse in the draft master plan the longer term needs of the airport beyond 20 years. That is unlikely to have been a result intended by the Parliament when enacting s 72. Of course, the airport lessee would need to specify its objectives for the new runway and relate them to the use of the airport during the planning period. But there is no express constraint in the Airports Act which would prohibit the airport lessee from explaining that its objective in developing the proposed runway is that by doing so the likely needs of the airport for the next 50 years will be met. Such an explanation may be needed to make sense of a proposal which would seem to be an overdevelopment if the only considerations to which the master plan could have regard were those inside the 20 year planning period (eg because the present or a smaller, less extensive, runway would suffice during that 20 year period).
68 And the environmental and planning consequences of Village's construction could be profound. First, neighbouring developing would be considered by State or Territory planning authorities in ignorance of what was likely to occur beyond the 20 year planning period (cf: s 71(6)). Thus, as Village wishes to occur here, properties in the vicinity of a flight path may be zoned to permit development which is compatible with all actual and potential use of the airport during the planning period, but is incompatible with the use intended more than 20 years hence. And once such incompatible development occurs, the airport may be constrained in being developed or used to meet the future needs of the city it services by the intervening development in the vicinity of the airport.
69 If the Tralee land were developed as residential land, the increase in the local population living there could add to demand over time for flights from Canberra airport. Yet the presence of that new development under the southern flight path could act as a practical constraint on the future increased use of the airport. That is the result for which Village contends here. It says that the ultimate capacity ANEF cannot be endorsed because it predicts a noise exposure for areas under the southern flight path 43 years hence. If that ANEF is used by the State planning authorities, Village will not be able, or will have to pay more, to develop residential land under the southern flight path, because in more than 20 years it will be affected adversely by noise in excess of the 20 ANEF contour. If Village is right, and is able to develop residential land because any valid ANEF, on its construction, cannot go beyond 20 years, then Canberra airport will not be able to be used at its maximum capacity, because the intervening residential development will be affected adversely in many years' time. Proper planning would seek to avoid such a result.
70 I am of opinion that a master plan will not be invalid if it contains additional or supplementary forecasts concerning matters which are required to be specified under s 71(2). Such additional or supplementary forecasts can extend beyond 20 years so long as the master plan also contains the forecasts which ss 71(2) and 72 require specifically to address and relate to the planning period. Those sections do not prohibit other matters from being considered in a master plan or being taken into account, in addition to the mandatory ones. And, s 71(4) specifically permits the actual matters specified in s 71(2) (as opposed to additional or supplementary ones) to relate to different periods if regulations are made to bring about such a result.
71 Indeed, the 2005 master plan for Canberra airport contains an ultimate practical capacity ANEF as at 2050 (par 10.5.5 and fig 10.5) and a comparison between the 20 ANEF contours for the 2050 ultimate practical capacity ANEF, the 2024 ANEC ('Australian Noise Exposure Concept') and the former 1997 ANEF (fig 10.6). A master plan which is approved by the Minister becomes a final master plan which comes into force at the time of the approval. It is unlikely that the inclusion of matters in addition or supplementary to those required to be included in a master plan were intended by the Parliament to have the effect of rendering invalid a draft or final master plan: Project Blue Sky 194 CLR at 391 [94]-[95]; see too at 381-382 [69]-[71], 384 [78] per McHugh, Gummow, Kirby and Hayne JJ, Clayton v Heffron 105 CLR at 247 per Dixon CJ, McTiernan, Taylor and Windeyer JJ. The consequence of Village's argument is so impracticable that it cannot have been intended in the absence of express words.
72 I am of opinion that the Airports Act,in requiring a master plan to relate to the 20 year planning period, does not preclude the master plan from addressing in addition matters, such as ANEFs, for lengthier periods. Such a construction gives effect to the objects in s 3 of promoting 'the efficient and economic development and operation of airports' and of promoting the sound development of civil aviation in Australia.
73 More significantly, the ANEF which s 71(2)(d) requires is one endorsed in a manner approved by the Minister. Other ANEFs not so endorsed are not proscribed from being prepared or checked for accuracy by a body such as Airservices. However, they will not be capable of satisfying the requirement of s 71(2)(d) unless endorsed under the Airports Act in a manner approved by the Minister.
74 I reject Village's arguments on this issue.
