Liquid waste generated during non-destructive excavation will be removed from the-site fortreatment and disposal.4.3 Air QualityExisting SituationHurstville City Council’s State of the Environment Report 2009-2010 reported that the regionalair quality in Hurstville was largely ‘good’. Local air quality is influenced predominantly by trafficemissions.Potential ImpactsLocal and regional air quality can be affected during construction by dust, construction vehicleemissions and odour. Dust may be generated from the disturbance of soils or poorly maintainedstockpile areas, which can affect human health or property. Poorly maintained vehicles canproduce excess emissions.The works will require energy to power vehicles (e.g. construction, delivery and staff vehicles)and construction plant. The energy requirements will primarily be in the form of fuel (petrol anddiesel). Fuel use will emit greenhouse gases with about 2.3 to 2.7 kilograms of carbon dioxideequivalent (CO 2 -e) per litre of fuel consumed (DEWHA 2008). In addition, indirect and thirdparty emissions will be generated as a result of energy used to produce materials (for examplesteel and concrete) – which is known as ‘embodied energy’.During operation, electricity will be required to power the facility, but the energy use will formonly a small contribution to TfNSW’s overall greenhouse gas emissions.Control MeasuresAir quality impacts throughout construction will be minimised through a range of controlmeasures which will include, but will not be limited to, those outlined below.Plant and equipment will be maintained in accordance with manufacturers’ specifications.Regular inspection of plant and equipment will be undertaken to ascertain that fittedemission controls are operating efficiently.Plant or machinery will not be left idling.Stockpiles will be maintained and contained appropriately, which could include covering orregular watering to minimise dust.Trucks transporting spoil and other waste materials from site will be covered appropriately.Disturbed areas will be rehabilitated as soon as practicable.Page 35 of 75
