aemcWambo Coal Mine, Rail Loop and Coal LoaderIndependent Environmental Audit – Minister’s Condition of ApprovalThe Receiver Land Owner locations are as detailed in theEnvironmental Impact Statement titled “Wambo DevelopmentProject”, Volumes 1-5 dated July 2003 prepared by ResourceStrategies Pty Ltd.L6.3 Noise from the premises is to be measured at the most affectedpoint or within the residential boundary or at the most affected pointwithin 30m of the dwelling (rural situations) where the dwelling ismore than 30m from the boundary to determine compliance withthe LAeq(15 minute) noise limits in condition L6.1.Where it can be demonstrated that direct measurement of noisefrom the premises is impractical, the EPA may accept alternativemeans of determining compliance. The modification factorspresented in Section 4 of the NSW Industrial Noise Policy shallalso be applied to the measured noise levels where applicable.L6.4 Noise from the premises is to be measured at 1m from the dwellingfaçade to determine compliance with the L A(1 minute) noise limits incondition L6.1.L6.5 The noise emission limits identified in condition L6.1 apply undermeteorological conditions of: Wind speeds of up to 3m/s at 10 metres above ground level; or Tspeeds of up to 2m/s at 10m above the ground.L7 Blasting limitsL7.1 Blasting in or on the premises must only be carried out between0900 hours and 1700 hours, Monday to Saturday. Blasting in or onthe premises must not take place on Sundays or Public Holidayswithout the prior approval of the EPA.L7.2 The airblast overpressure level from blasting operations in or onthe premises must not exceed:(a) 115 dB (Lin Peak) for more than 5% of the total number ofblasts during each reporting period; and(b) 120 dB (Lin Peak) at any time.At any residence or noise sensitive location that is not owned bythe licensee or subject of a private agreement between the ownerof the residence or noise sensitive location and the licensee as toan alternative overpressure level .

No blasts exceeded 120dBL.2008-2009: 2 of 102 blasts exceeded 115 dBL (i.e. 2%)therefore compliant. One blast exceeded 120dBL (120.3dBL atKelly monitoring site on 13 October 2008) was reported toDECC.2009-2010: 2 of 62 blasts exceeded 115dBL (i.e. 5%)therefore compliant. One blast exceeded 120dBL criteria(122.1dBL at Harris monitoring site 14 August 2009) wasreported to DECCW.2010-June 2011: One blast exceeded120dBL (i.e.124.2dBL atMuller monitoring site on 17 February 2011) was reported toDECCW.trevor brown & associates 111applied environmental management consultants
