Info

Assessment of the environmental impacts and risksCommunicate with the impacted residents by clearly explaining the duration,nature of works prior to and during works together with provision of complaints linethat will record the type of complaint and time etc.Ensure all equipment is turned off when not in use.3.6 Indigenous heritage3.6.1 Existing environmentA search of the Aboriginal Heritage Information Management System (AHIMS)database maintained by the NSW Office of Environment and Heritage was undertakenon 29 February 2012 for areas with the potential of being impacted during theproposal. A copy of the search area and results is located in Appendix D. This searchidentified no Aboriginal heritage item located within the search area.3.6.2 Impact assessmentPotential impacts on items of Aboriginal heritage significance would be associatedwith ground surface disturbance that is required as part of the proposal. Theseearthworks have the potential to uncover unknown Aboriginal heritage items. Thelikelihood of the regrading works uncovering unknown items is considered to bereduced as these areas have been heavily disturbed in the past due to theconstruction of the rail line.Based on the results of the AHIMS search and site inspection, an assessment hasbeen undertaken in accordance with the Due Diligence Code of Practice for theProtection of Aboriginal Objects in New South Wales (DECCW, 2010) concluded thatthe proposal is unlikely to impact on items of Aboriginal heritage significance.3.6.3 Recommended control measuresThe following measures would be implemented to minimise potential heritage impacts:Should any Aboriginal heritage items be uncovered during construction, all workswould cease within the vicinity of the find and RailCorp’s site supervisor andEnvironmental Officer would be contacted.3.7 Non-indigenous heritage3.7.1 Existing environmentA desktop assessment was undertaken on 29 February 2012 which included searchesof the following databases, heritage lists and registers:Australian Heritage database (National Heritage List, Commonwealth Heritage Listand Register of the National Estate)NSW State Heritage RegisterState authority Section 170 registersWarrawee Substation Project/Review of Environmental FactorsPage 36 of 64
Assessment of the environmental impacts and risksKu-ring-gai Planning Scheme OrdinanceResults of the searches indicated that there are no heritage items or conservationareas in the vicinity of the site. The nearest item to the site is a house with localheritage significance under the Ku-ring-gai Planning Ordinance Scheme, located at 41Brentwood Avenue approximately 200 metres east of the site.3.7.2 Impact assessmentThe proposal is not located in the vicinity of any items of State Heritage significance.The nearest heritage item is a locally listed item at 41 Brentwood Avenue. Theproposal is located approximately 200 metres west of 41 Brentwood Avenue. As suchthe proposal would not result on any impacts to this property. In addition, the visualfootprint of the proposal is unlikely to significantly affect the heritage significance ofthe item due to the relative distance between the proposal and the property.3.7.3 Recommended control measuresThe following measures would be implemented to minimise potential non-Indigenousheritage impacts:If any archaeological items of non-indigenous heritage significance areencountered during the course of the construction period, works would cease andRailCorp’s site supervisor and environmental officer would be contacted. OEHwould be contacted in accordance with the Heritage Act 1977.3.8 Waste3.8.1 Existing environmentThe site is located within the rail corridor and does not generate significant wastestreams. General maintenance of the corridor (rail infrastructure and vegetation)results in some waste which is disposed of in accordance with RailCorp’smaintenance procedures.3.8.2 Waste generationWaste generated during the construction phase would be limited to surplus buildingmaterials, such as concrete, brick, and cladding, and spoil. General waste, such assurplus pipe and cabling associated with connecting the site to services would also beproduced. Careful planning of construction activities would ensure that the volume ofsurplus materials is minimised. The small scale of this building means that a smallvolume of waste in comparison to other larger infrastructure construction projects islikely to be generated as a result of surplus materials.As indicated in Section 3.1.2, asbestos was historically used in brake linings and thereis the potential for fragments to be present in the soil. If suspected contaminatedmaterial is encountered during construction, the control measures recommended inSection 3.1.3 would be implemented.Warrawee Substation Project/Review of Environmental FactorsPage 37 of 64
