Warrawee Substation - Review of Environmental Factors

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
