• Any spoil or waste material tracked onto roads will be swept up immediately.• Adequate numbers of bins and waste containers will be placed at the site. The site managerwill ensure bins are not overflowing and are appropriately covered.• All waste will be removed from the site when work is completed.4.8 Contaminated LandExisting SituationThe site has been investigated for potential land contamination. The investigation included:• a visual inspection for signs of potential land contamination;• a search of the NSW Office of Environment and Heritage (OEH) register ofcontaminated sites;• a search of RailCorp records; and• a review of all materials to be used at the site to establish their potential for landcontamination.The initial investigation did not find any signs of potential land contamination, other than thosetypically associated with rail corridors. There are no visible and/or obvious signs ofcontamination in the vicinity of the site. No waste dumping, soil discoloration, odours and/orsimilar were noticed.RailCorp does not have any record or evidence that the site is contaminated. The closest siteon the OEH list is BHP Area 21 at Springhill Road, about 2.5 kilometres away.Hazardous materials will not be used during construction and operation and, therefore, theproposed work will not result in any new site contamination.Potential ImpactIt is highly unlikely that the site can be contaminated by known activities or by contaminantsmigrating from known contaminated sites.However, the limited investigation cannot exclude potential contamination as the result ofunknown past activities, either on the site or in the vicinity.As intrusive works are not proposed, there is minimal risk that contaminants could beencountered during the proposed work.Risk Management and Possible ControlsAs no intrusive works are proposed, no control measures are required.Page 37 of 64
