Cowal Gold Project – Noise Management Plan• meteorological conditions, including temperature inversions;• nature of complaint; and• response action taken to date.The complaints register will be updated and attended to by the Environmental Manager.6.3 IDENTIFICATION OF HIGHER LEVEL IMPACTS OR PATTERNS BETWEEN NOISECOMPLAINTS AND TEMPERATURE INVERSIONSIn accordance with Consent Condition 6.4(a), data from the on-site meteorological station will be usedto determine the existence of temperature inversions (Section 6.1). The occurrence of anytemperature inversions will be compared with noise complaint details (Section 6.2) to determinewhether any higher level of impacts or patterns of temperature inversions have occurred.The details of complaints received by the Environmental Manager will be entered into the complaintsregister. The receiving of any complaints will prompt the Environmental Manager to assess whethertemperature inversions are contributing to the noise complaint.Higher level impacts in relation to temperature inversions will only be apparent after a number ofcomplaints during temperature inversions have been received. Higher level impacts in relation totemperature inversions will be presented in the AEMR (Section 17).6.4 QUANTIFICATION AND AMELIORATION OF ENHANCED IMPACTS DUE TOTEMPERATURE INVERSIONSQuantificationIn accordance with Consent Condition 6.4(a)(ii), should enhanced noise impacts be identified in theprocess described in Section 6.3, monitoring will occur at the source of the complaint to quantify thedegree of enhanced impact against noise exceedance criteria. Monitoring should be undertaken bothduring periods of temperature inversion and during the daytime, when temperature inversions are notexperienced, to enable quantification of the contribution of the temperature inversion to noise impacts.AmeliorationWhere numbers of noise complaints indicate higher levels of noise impact due to temperatureinversions, as quantified (Section 6.4), measures will be taken to ameliorate enhanced impacts undertemperature inversion conditions. Noise reduction strategies and procedures for reducing noiseemissions from the Project are outlined in Section 10, whilst Section 11 details remedial measuresthat could be applied.7 NOISE INVESTIGATIONS PLANIn accordance with Consent Condition 8.4(a)(i), monitoring will be conducted at near-by residencesand bird breeding areas to evaluate, assess and report the L A10(15 minute) and L Aeq(15 minute) noise emissionlevels due to normal operations of the mine during prevailing conditions, except during:• rain; and/or• wind speeds greater than 3 m/s; and/orHAL-02-07/1/NMP01-P/17/11/04 19 BARRICK
