Assessment of the environmental impacts and risksTable 3.14Summary of control measuresIssueLandforms,geology and soilsEcologyWater quality andhydrologyControl measuresAn erosion and sedimentation control plan would bedeveloped and incorporated into the ConstructionEnvironment Management Plan (CEMP). The plan wouldincorporate specifications outlined in the Managing UrbanStormwater, Soils & Construction, Volume 1 (Landcom 2004),identify areas requiring management controls, includeinspections and checklist sheets.Disturbed surfaces would be stabilised as soon as possible tominimise erosion and sedimentation.Spoil would be reused on site where possible.In the event spoil cannot be reused on site, spoil would bestored, transported, disposed of in accordance with the DECCWaste Classification Guidelines (2008).Maintenance and checking of the erosion and sedimentationcontrols would be undertaken on a regular basis and recordswould be kept and provided to regulatory authorities at anytime upon request. Sediment would be cleared from behindbarriers on a regular basis and all controls would be managedin order to work effectively at all times;Any material transported onto pavement surfaces would beswept and removed as required.Site rehabilitation of disturbed areas would be undertakenprogressively as stages are completed.In the event that contaminated soils are encountered duringconstruction, work would cease and an environmentalconsultant would be contacted to advise on the need forremediation or any other management actions.Disturbed areas would be restored to their natural shapewhere possible at the completion of works.The small strip of native vegetation along the cutting in thenorth of the site should be fenced prior to construction. Allconstruction activities should be excluded from this area.All fuels, chemicals, and dangerous goods would be storedaway from any waterways or drainage lines and would bestored in an temporary bund or similar within the sitecompound if practicable.All staff would be inducted into the incident emergencyprocedures and made aware of the location of where theemergency spill kits would be keptThe refuelling of plant and maintenance of machinery wouldWarrawee Substation Project/Review of Environmental FactorsPage 54 of 64
Assessment of the environmental impacts and risksIssueAir qualityControl measuresbe undertaken in impervious bunded areas. This may involveusing temporary impervious bunded areas.Machinery would be checked daily to ensure there is no oil,fuel or other liquids leaking from the machineryExcess concrete would be scraped off equipment beforebeing washed. All remaining concrete residue would becollected and disposed of to a licensed landfillVehicle wash downs and/or concrete truck washouts would beundertaken within a designated bunded area of an impervioussurface or undertaken off-siteAn incident emergency spill plan would be developed andincorporated into the CEMP. The plan would includemeasures to avoid spillages of fuels, chemicals, and fluidsonto any surfaces or into any adjacent/nearby waterways andan emergency response plan. An emergency spill kit would bekept onsite at all times.Should a spill occur during construction, the emergencyresponse plan would be implemented, and the RailCorpenvironmental officer contacted. The Office of Environmentand Heritage would also be notified if the impacts of the spillare considered to result in material harm to the environment(as per Part 5.7 of the POEO Act).RailCorp would investigate the feasibility of connecting theoil/water separator which forms part of the proposal duringconstruction to assist in minimising the impacts of spills duringconstruction.All equipment would be roadworthy, regularly maintained andinspected daily.Equipment used and all facilities erected would be designedand operated to control the emission of smoke, dust, fumesand other pollution into the atmosphere.Excavation equipment and procedures would be selected tominimise dust generation, where practicable.A water cart or fixed hoses would be used to dampen exposedsurfaces to minimise dust generation.Shade cloth would be fastened to the perimeter fence on theconstruction compound to minimise dust transported from thesite during construction.Working areas would be stabilised as soon as practical toprevent or minimise windblown dust.Handling areas would be maintained in a condition thatWarrawee Substation Project/Review of Environmental FactorsPage 55 of 64
