4.2 Low Frequency Assessment Table 4.5 provides statistics for attended noise monitoring undertaken around Mangoola Coal during Quarter 3 2012. Table 4.5 ATTENDED MEASUREMENT STATISTICS FOR MANGOOLA COAL – QUARTER 3 2012 Conditions Total for Quarter 3 2012 Number of measurements 15 Number of measurements where Mangoola Coal was measurable and criterion applied 2 A total of 2 out of 15 measurements occurred during which Mangoola Coal was measurable (not “inaudible” or “not measurable” or “

Mangoola Coal only L Aeq provided as a guide; 2. Day and night L Ceq criterion as detailed in Broner (2010); 3. These are measured C-weighted noise levels (at frequencies less than 250 Hz) and are not always the result of activity at Mangoola Coal. Guidance on this is provided in the Comments column; and 4. Bolded results in red are those greater than the relevant criterion. Nil Table 4.8 provides measured levels and adjustments in accordance with INP modifying factors. Discussion as to the noise sources responsible for these measured levels is provided in Section 5 of this report.

Wind speed and sigma theta data sourced from Mangoola Coal meteorological stations. Data from the nearest met station to the monitoring location was used. Sigma theta data used to calculate Vertical Temperature Gradient (VTG) in accordance with procedures detailed in the INP; 2. Noise emission limits apply for the following meteorological conditions: • wind speeds of up to 3 m/s at 10 metres above ground level; or • temperature inversion conditions of up to 3ºC/100m, and wind speeds of up to 2m/s at 10 metres above ground level; 3. Y denotes Yes, N denotes No; 4. These are results for Mangoola Coal in the absence of all other noise sources; and 5. Bolded results in red are those greater than the relevant criterion. 17 12324_R01.doc Page 17
