Cowal Gold Project – Noise Management Plan7.2.5 Selecting LocationsMonitoring locations have been agreed with NPWS (NPWS, pers. comm., 21 May 2003) as follows(Figure 3):• NO1 - New Lake foreshore;• NO2 - ‘Coniston’ residence;• NO3 - bird breeding area;• NO4 - bird breeding area;• NO5 - ‘Gumbelah’ residence; and• NO6 - ‘Lake Cowal’ residence.7.2.6 Survey Periods and Times of MeasurementIn accordance with Consent Condition 8.4(a)(i), operator attended noise monitoring will be conductedsix monthly at locations identified in Section 7.2.5.At each monitoring site, operator attended noise monitoring will be conducted using a Type 1 nonintegratingsound level meter over a 15 minute period on at least one occasion during the daytime(7am–10pm) and night-time (10pm-7am) as described in section 6.4(a) of the Consent Conditions.During the survey, the operator will identify the character and duration of acoustically significant noisesources. This monitoring is referred to as short-term monitoring in the INP (Appendix A).In conjunction, unattended noise monitoring will also be conducted at locations in Section 7.2.5.Section 3.5 of the INP (Appendix A) specifies a one week period for establishing noise levels with thismonitoring referred to as long-term monitoring. This period will be adopted for unattended monitoringfor Project operations. Unattended long-term monitoring would occur every six months duringoperations, to complement the operator attended short-term noise monitoring.7.2.7 Means of Determining Noise LevelsInstrumentationSection 5.3 of AS 1055.1-1997 (Appendix C) states that instrumentation to be used for measurementof exceedance of “A”-weighted sound pressure level (L A10(15 minute) ) may include but is not limited to:• Type 1 sound level meter set to frequency-weighting “A” and time-weighting “F” with built-incapability for measuring this descriptor; and/or• Data analyser for sampling the running value of “A”-weighted sound pressure level.In order to measure against operations noise criteria (e.g. L Aeq(15 minute) ) an integrating averaging soundlevel meter will be used in accordance with AS 1259.2-1990 (now superseded by AS IEC 61672.1-2004 [Appendix D] and AS IEC 61672.2-2004 [Appendix E]).HAL-02-07/1/NMP01-P/17/11/04 21 BARRICK
