Review of Environmental FactorsGlenbrook commuter car park and interchange upgradeNumberSafeguards and mitigation measuresSoils66 Erosion and sediment control plans would be prepared in accordance withManaging Urban Stormwater: Soils and Construction Guidelines(Landcom/Department of Housing). The erosion and sediment control plans wouldbe established prior to the commencement of construction and be updated andmanaged throughout as relevant to the activities during the construction phase.Measure would include:• Stabilised surfaces would be reinstated as quickly as practicableafter construction• All stockpiled materials would be stored in bunded areas and keptaway from waterways to avoid sediment entering the waterways.• Sediment would be prevented from moving off‐site and sedimentladen water prevented from entering any watercourse, drainageline or drainage inlet.• Any material transported onto pavement surfaces would be sweptand removed at the end of each working day.• Clean water would be diverted around the work site.67 Erosion and sediment control measures would be regularly inspected (particularlyfollowing rainfall events) to ensure their ongoing functionality.68 Erosion and sediment control measures would be left in place until the works arecomplete and areas are stabilised.69 Works would be avoided during rainfall (or whilst the ground remains sodden) tominimise vehicle disturbance to the topsoil.70 Excavated soils for disposal/reuse would be tested during construction todetermine appropriate waste classification. Further toxicity characteristicsleaching procedure testing would also be undertaken in the field whileconstruction is being undertaken to fully classify the waste if it is not able to beclassified as virgin excavated natural material (VENM).Hydrology and water quality71 Adequate water quality and hazardous material procedures (including spillmanagement procedures, use of spill kits and procedures for refuelling andmaintaining construction vehicles/equipment) would be implanted during theconstruction of the project.Ref No: 2260812 77
