Minimising our environmental footprint – Noise
The generation of noise is an unavoidable characteristic of some of our business activities. Many of our projects involve the development of rural land that is already occupied and used for other purposes by third parties. The management of noise is vitally important in such settings, where background noise levels are low and amenity expectations are high.
Some community stakeholders continue to be concerned about infrasound and low frequency sound arising from the operation of wind farms. Sound at or below these levels is considered to be inaudible to the human ear. We are supporting new scientific research into wind turbines and infrasound health impacts. For example, we are cooperating with researchers from Flinders University in a study measuring the effects of noise from our Hallett Hill Wind Farm on sleep at neighbouring residences. We continue to work closely with the National Wind Farm Commissioner and landholders neighbouring our Macarthur, Hallett and Wattle Point wind farms.
Noise monitoring conducted in FY17 at AGL’s Oaklands Hill Wind Farm has confirmed that the wind farm is operating within the permitted noise levels. The Macarthur Wind Farm was determined by the Moyne Shire Council to be operating in compliance with the New Zealand Standard Acoustics – The Assessment and Measurement of Sound from Wind Turbine Generators (NZS 6808:1998) and confirmed that AGL satisfactorily met its compliance condition.
Quarterly noise monitoring conducted for the Camden Gas Project during FY17 has confirmed that noise emissions recorded at sensitive receiver locations are compliant with environmental licence conditions.
AGL will continue to monitor and manage the output of noise from its activities to ensure it remains compliant with its obligations.
