Cowal Gold Project – Noise Management PlanInstrumentation Set-upSection B2.1 of Appendix B of the INP (Appendix A) outlines instrumentation and siting requirementsfor operator attended short-term monitoring. The following actions will be undertaken when setting upinstrumentation:• fit a windshield over the microphone before taking measurements;• ensure that the equipment has a current laboratory calibration certificate or label in accordancewith the calibration requirements outlined in AS 1259.1-1990 (now superseded by AS IEC61672.1-2004 [Appendix D] and AS IEC 61672.2-2004 [Appendix E]) and AS 2659.1-1988(Appendix F);• calibrate the equipment in-field in accordance with AS 1259.1 (now superseded by AS IEC61672.1-2004 [Appendix D] and AS IEC 61672.2-2004 [Appendix E]) and AS 2659.1(Appendix F);• hold the sound-level meter at arm’s length or set-up on a tripod so that the microphone is 1.2 to1.5 m above the ground and at least 3 to 5 m from any walls; and• set the meter to “Fast” time weighting and “A” frequency weighting.Section B1.1 of Appendix B of the INP (Appendix A) outlines instrumentation and siting requirementsfor unattended long-term monitoring. The following actions will be undertaken when setting upinstrumentation:• fit a windshield over the data logger before taking measurements;• ensure that the equipment has a current laboratory calibration certificate or label in accordancewith calibration requirements outlined in AS 1259.1 (now superseded by AS IEC 61672.1-2004[Appendix D] and AS IEC 61672.2-2004 [Appendix E]) and AS 2659.1 (Appendix F);• calibrate equipment in-field in accordance with AS 1259.1 (now superseded by AS IEC 61672.1-2004 [Appendix D] and AS IEC 61672.2-2004 [Appendix E]) and AS 2659.1 (Appendix F);• position the data logger microphone 1.2 to 1.5 m above ground level and at least 3 to 5 m fromany walls;• position data logger as far away from trees as practicable to avoid noise produced by windblowing through foliage; and• set the meter to “Fast” time weighting and “A” frequency weighting.Noise monitoring proceduresIn accordance with Consent Condition 8.4(a)(i), monitoring will occur during prevailing conditions,except during:• rain; and/or• wind speeds greater than 3 m/s; and/or• temperature inversions greater than 8.0 o C/100 m and wind speed greater than 1 m/s at 10metres above ground level. Note that the 1 m/s drainage-flow wind constraint will only applywhere the development is at higher altitude than the residential receiver, with no interveninghigher ground.HAL-02-07/1/NMP01-P/17/11/04 23 BARRICK
