Review of Environmental FactorsGlenbrook commuter car park and interchange upgradeworks) are located adjacent to this receiver. Exceedances of the LAeq(15minute) noise goal of up to25 dBA are predicted at this receiver location during the daytime period.Workzone C (Installation of Power Poles)For the Workzone C works, the noise predictions indicate that worst‐case LAeq(15minute) constructionnoise levels of up to 70 dBA are expected at the nearest residential receiver when scenario 12 works(installation of power poles) are located adjacent to this receiver. Exceedances of the LAeq(15minute)noise goal of up to 23 dBA are predicted at this receiver location during the daytime period.Should OOHW for scenario 12 be required, exceedances of the LAeq(15minute) noise goal of up to32 dBA are predicted at the nearest receiver location during the evening OOHW period.Highly Noise Affected ReceiversReceivers located adjacent to the proposed Workzone A (commuter car park) are predicted to besubjected to noise levels which exceed 75 dBA during construction scenario 3 (site clearing and bulkearthworks).Receivers located immediately adjacent to the proposed Workzone B (pedestrian improvement worksand mobility parking provision) are predicted to be subjected to noise levels which exceed 75 dBA duringconstruction scenario 4 (excavation and installation of drainage and services trench).These receivers would therefore be considered as ‘highly noise affected’ during the respective works, asdefined by the ICNG. Mitigation measures to minimise impacts to residents are discussed in more detailin Section 6.4.6.Construction Vibration AssessmentThe proposed activities are considered to either contain plant items that are not significantly vibrationintensive and/or the separation distance from the nearest receivers is sufficient to mitigate the potentialimpacts, and as such have not been considered further in this assessment.Construction Ground‐borne Noise AssessmentAll of the proposed plant items are not considered to have potential to cause adverse ground‐borne noiseimpacts and as such have not been considered in this assessment.6.4.4 Operational noise assessment criteriaThe noise limits for the operational noise emissions from the proposed commuter car park are derivedfrom the NSW EPAs Industrial Noise Policy (INP).The INP sets two separate noise criteria: one to account for intrusive noise and the other to protect theamenity of particular land uses. These criteria are to be met at the most‐affected boundary of thereceiver property.Ref No: 2260812 46
