APPENDIX A: Influence of Construction Noise on Background Noise Levels

Construction activity during the background noise monitoring period was limited to road construction in the southern portion of the wind farm, in the vicinity of Big Hill Road and Warrak Road. Given the low intensity of the construction activity, the noise was not expected to influence the measured noise levels. Notwithstanding, an assessment has been made to determine if the construction activity had any influence on the measured noise levels.

Noise and wind data collected during the period when the construction activity ceased over the Christmas and New Year period (between 25 December 2015 and 10 January 2016) have been correlated and compared with the results for the entire monitoring period. The following table provides a comparison of the measured background noise level for integer wind speeds during the two-week shut down period, and during the entire monitoring period:

Monitoring Construction Background Noise Level, LA95,10 (dB(A)) at 85m Hub Height Integer Wind Speeds Location ID Activity 4 m/s 5 m/s 6 m/s 7 m/s 8 m/s 9 m/s 10 m/s 11 m/s 12 m/s 13 m/s 14 m/s No 27 28 29 31 33 35 37 39 41 42 43 AH10 Yes 27 28 29 30 32 34 36 38 40 42 44 No 32 32 32 33 34 35 36 38 40 42 44 AH12 Yes 30 30 31 32 33 34 36 37 39 40 41 No 34 34 34 35 35 36 37 39 40 41 43 AH13 Yes 32 31 32 33 34 35 37 38 39 40 39

The comparison above shows that the measured background noise levels do not increase when the construction activity was occurring, and therefore indicates that the construction activity did not influence the measured background noise levels.
