ERM has been working with Aviation Projects for over three years on various wind farm development projects, with positive tangible results for our business and, more importantly, for our clients. The industry leading expertise, level of professionalism and meticulous attention to detail delivered by Aviation Projects are a reflection of the high standards that they set for themselves. The client’s desired outcomes are always of the highest consideration and adherence to standards and regulations are paramount.
I highly recommend Aviation Projects to any business that needs to identify and address potential aviation safety impacts in order to secure a development approval.
In the matter of Naroghid Wind Farm Pty Ltd v Minister for Planning  VCAT, Keith Tonkin appeared as an aviation operations and airport planning expert for the Minister for Planning.
The engagement included attending a site visit to Cobden airfield, preparing an expert report, preparing a reply report, attending the hearing and providing post-hearing expert advice.
What was the proceeding about?
The applicant, Naroghid Wind Farm Pty Ltd, previously held a planning permit allowing it to develop a 25 turbine wind energy facility (a wind farm) on land to the north-west of Cobden. That permit was issued in 2006 by the Minister for Planning, acting upon recommendation of a planning panel. That permit was not acted upon and had expired.
The applicant applied for a new planning permit to develop a revised wind farm. This proposed wind farm would comprise 12 turbines which would be taller than those authorised by the previous permit. The land on which this new wind farm proposal would be developed is part of the land on which the previously approved wind farm was to be developed, but it would extend over a smaller area.
When the Minister for Planning did not make a decision on the permit application within the statutory timeframe, the applicant lodged an application for review with the Tribunal.
The Minister for Planning subsequently advised the Tribunal that if the application for review had not been made, the Minister’s decision would have been to refuse to grant a permit. This was for two reasons:
- significant concern about the effect of the wind farm turbines on the safety and efficiency of the Cobden airfield, including any future development or expansion of this facility; and
- the survey material put forward by the applicant was not sufficiently complete, robust or rigorous enough to enable proper assessment of the likely impact of the proposal on the critically endangered Southern Bent-wing Bat (Miniopterus orianae bassanii) known to frequent the region.
The Minister argued that the Tribunal should not grant a permit for the same reasons.
The concerns of the Minister about the impact on safe aviation operations at the Cobden airfield were shared by its owner, the Corangamite Shire Council. The Council also opposed the proposed windfarm on the basis that it will adversely affect the current and future operations of the Cobden airfield in a manner which was inconsistent with relevant planning policies.
Users of the Cobden airfield and local residents in the surrounding area also opposed the proposed windfarm on the basis of what they said would be the impacts on the Cobden airfield. Residents also raised a number of other concerns about noise, shadow flicker, traffic, electromagnetic transmission and visual amenity impacts.
The Tribunal refused to grant a permit for the proposal.
What the Tribunal found (in relation to aviation impacts)
(Extracted from the Tribunal's Reasons for its Decision)
259 On the evidence before us, we have found that the proposal will have a material impact on the current operations of the Cobden airfield. Even the proponent’s own experts acknowledge that the proposal will give rise to safety issues and recommend measures to be implemented by the Cobden airfield to enable it to continue its current day time operations.
260 If we were to approve the proposal, it would be up to the Cobden airfield to undertake the necessary changes to its operation to address the additional safety risks arising from the proposal. We agree with the Council and the Cobden Aero Club that the measures it would need to adopt to mitigate safety risks arising from the proposal would have a material impact on the current operations of the Cobden airfield. These impacts include cessation of the current night time use of the Cobden Airfield, constraining the way in which pilots can use the existing runways and relocating the existing circuit area away from less sensitive farming land to an area around the Cobden township itself.
261 We consider these impacts of the proposal on the current use of an existing public asset to be a factor which weighs against it. We consider this to be a significant factor given that the Cobden airfield is an asset expressly recognised in the scheme, with policy support for the protection of its ongoing operation and the community benefits that arise from its use.
262 We also consider reducing the existing separation between the use of the airfield and the township of Cobden, so that aircraft using the airfield would fly closer to the Cobden township, creates a situation of potential land use conflict which is inconsistent with orderly planning and which could impact on the amenity of the residents of the Cobden township. This detriment to the Cobden township as a whole is another matter which we consider weighs against the proposal when assessing its net community benefit.
