aemcWambo Coal Mine, Rail Loop and Coal LoaderIndependent Environmental Audit – Minister’s Condition of Approval4 The Applicant shall ensure that all construction work is carried outfrom 7 am to 6 pm Monday to Saturday (inclusive) and 8 am to 6 pmSundays and Public Holidays.Operating Hours5 The Applicant shall:(a) take all practicable measures to minimise train movements at thedevelopment on Friday evening (6 pm-9 pm) and Sunday morning (9am-12 am);(b) report on the implementation and effectiveness of these measures,to the satisfaction of the Director-General.Monitoring6 The Applicant shall monitor the noise generated by the developmentat least 4 times a year at a minimum of 3 representative locations nearthe site, in general accordance with the NSW Industrial Noise Policyand AS1055-1997: Acoustics – Description and Measurement ofEnvironmental.7 Before carrying out any development, the Applicant shall prepare aNoise Monitoring Program for the development to the satisfaction ofthe Director-General, which includes a noise monitoring protocol forevaluating compliance with the criteria in Table 2.BLASTING AND VIBRATIONAirblast Overpressure Criteria8 The Applicant shall ensure that the airblast overpressure level fromblasting at the development does not exceed the criteria in Table 3 atany residence on privately owned land.Table 3: Airblast overpressure impact assessment criteriaAirblast OverpressureAllowable ExceedanceLevel (dB(Lin Peak))115 5% of total number of blasts over 12mths120 0% Quarterly EnvironmentalNoise Monitoring Reports,Global Acoustics, 2007-2010 Construction/OperationalNoise Management Planand Monitoring Program,Jan 2005 Noise Monitoring Program,May Rev 3 2007 Letter from DoP re Approvalof the Noise MonitoringProgram, 2 Nov 2007 Quarterly EnvironmentalNoise Monitoring Reports,Global AcousticsYes(Completed)YesYesYesYes(Completed)Construction works associated with the rail loader and railloop were conducted during normal work hours (i.e. 7:00am to6:00pm Monday to Saturday).Train movements are determined by the availability of railaccess and where practicable train movements conform withthis condition.Noise monitoring is conducted quarterly for the noisegenerated by the rail loop and coal loader and the results arereported in the AEMR‟s. The quarterly monitoring duringconstruction was conducted using noise loggers placed nearthe Henderson, Kelly, Haynes and Dyson residences, during2005.Rail pass-by monitoring is conducted on the Wambo Coal RailSpur at the Dyson property. Sound exposure level (SEL) andL Amax recorded for a total of three empty trains, and threeloaded trains at this location were used to ensure consistentdata is collected and assessed (atypical data can then beidentified and excluded if required).A Construction/Operational Noise Management Plan andMonitoring Program for the Wambo Rail Development wasprepared and implemented in January 2005.The noise monitoring program for the rail operations wasincluded into the Wambo Noise Monitoring program in 2007,following commencement of operation of the rail loop andloader. The revised Noise Monitoring Program was approvedby the DoP on 2 Nov 2007.Airblast overpressure during the construction of the rail loopwere compliant with the 1115 dBL criteria and no blastsexceeded the 120dBL criteria.trevor brown & associates 98applied environmental management consultants
