Executive Summary Global Acoustics was engaged to conduct an attended noise survey around Mangoola Coal (XMC), an open cut coalmine near Wybong in the Upper Hunter Valley of NSW. The purpose of this noise survey is to quantify and describe the acoustic environment around the site and compare results with limits specified in the consent. Environmental noise monitoring described in this report was undertaken during the day period of 4 July, the evening of 11 July and night periods of 5/6 July and 11 July 2012. Night monitoring was completed over two separate visits as rain occurred on the first night. As shown in Section 4 of this report, Mangoola Coal complied with the relevant day, evening and night consent L Aeq(15 minute) noise limits and night L A1(1 minute) noise limits, where applicable, at all sites during Quarter 3 2012 monitoring. A total of 2 out of 15 measurements occurred during which Mangoola Coal was measurable and where meteorological conditions resulted in criteria applying (in accordance with the project approval). A post analysis of these three results was carried out for low frequency content. The low frequency assessment carried out in accordance with the INP and Broner methods identified exceedances of both low frequency criteria at Roxburgh Road (A5) during the night period of 11 July 2012. A 5 dB penalty was applied to the measured result from this location in accordance with the INP method. The penalty resulted Mangoola Coal noise levels being equal to the project approval and EPL impact assessment criteria at Roxburgh Road (A5). Global Acoustics Pty Ltd 12324_R01.doc Page ii
