A two-way information exchange between individuals or groups. Any resident, landowner, business, community or interest group who has an interest in the development of a wind farm at a particular location from an economic, social or environmental perspective. This may include people that have or might have wind turbines or associated infrastructure on their land, neighbours of the wind farm, nonneighbouring residents within the vicinity of the wind farm, local and other businesses (and their customers), tourists visiting the region, and the broader community outside of the region. Other Interested Stakeholder Planning Authorities Local Planning Authority Project Landowner Neighbouring Landowner An interested stakeholder is a person, business or organisation who has an interest or association with a wind energy facility development. This interest can often be much narrower than the community, generally focussing on individual issues or groups of issues. Other interested stakeholders may include Government Ministers without planning jurisdiction (e.g. environment and energy ministers), the Bureau of Meteorology (BoM), the Civil Aviation Safety Authority (CASA), Department of Defence, fire authorities, bird observers clubs, and telecommunications businesses. . A planning authority is a government body that has a role in providing a policy framework for wind farm development and for assessing and approving applications for wind farm development. They also have a role post-approval in ensuring developments comply with statutory (legal) requirements and development consent conditions (which may be statutory or non-statutory). Depending on the jurisdiction and the size of the project, the planning authorities involved may include local councils, State or Territory government departments or agencies, and the Commonwealth Department of the Environment, Water, Heritage and the Arts. See description above. Within this appendix the local planning authority refers to the governing body (local council) of the jurisdiction in which the wind farm project is located. An individual who has an agreement with a wind farm developer to host wind turbines or associated components on their land. An individual who owns land adjacent or in proximity to a wind farm development (Generally this refers to landowners within 3kms of a wind farm properties boundary).

B Noise B.1 Introduction This Appendix addresses the noise emissions from wind farms. The purpose of the Appendix is both to outline the noise assessment process for wind farm neighbours, including stakeholders, and to provide sufficient detail of relevant issues to assist the wind farm developer with a noise impact assessment for a proposed wind farm. The aim of the information provided here is to ensure that a fair and robust noise impact assessment is carried out, to a nationally consistent standard. This should provide greater certainty not only to the wind farm developer but also to the wind farm neighbour. The Australian Standard 4959–2010 Acoustics – Measurement, prediction and assessment of noise from wind turbine generators is recognised herein and should form the basis for any noise impact assessment. Supplementary guidance is provided to complement the Standard and advise on issues which are outside of its scope but are still pertinent to wind farm noise emission. In particular, guidance is provided to establish noise criteria, and recommendations are made to assist with noise emission prediction modelling. Community consultation is also included in appropriate phases of the assessment process and is expected to be a key component of any wind farm development. Noise impact assessment is addressed in the following phases: • Noise impact risk assessment • Preliminary noise impact assessment • Noise impact assessment • Preparation of expert evidence, as required • Construction noise • Post-construction noise monitoring • Decommissioning. A glossary of technical terminology used throughout this appendix is provided in Section B.6. Unless otherwise stated, all wind speeds in this Appendix are referenced to hub height. B.2 Recommended Form of Noise Criteria B.2.1 Basic description of issues addressed in the Guidelines Wind farm noise emission What distinguishes wind turbine noise emission from more conventional sources of sound is that it tends to increase with increasing wind speed. AS4959–2010 notes that: … it is a unique characteristic of a WTG [wind turbine generator] or wind farm that the noise level from each WTG will increase with increasing wind speed and that the background noise within the ambient noise environment at receivers will generally also increase under these conditions. This introduces challenges of measuring and assessing noise emission from wind turbines while concurrently considering the presence of wind effects and other noise sources caused by wind in the environment.
