Plant and equipment will be checked regularly for oil leaks. Plant and equipment will not be refuelled on site. Wash down areas will be located away from waterways and drainage lines. Liquid waste generated during non-destructive excavation will be removed from the-site for treatment and disposal. 4.3 Air Quality Existing Situation Wollongong City Council’s State of the Environment Annual Report 2011-2012 reported that the regional air quality in Wollongong was largely ‘good’. Local air quality is influenced by domestic and industrial emissions and prevailing weather conditions. Potential Impacts Local and regional air quality can be affected during construction by dust, construction vehicle emissions and odour. Dust may be generated from the disturbance of soils or poorly maintained stockpile areas, which can affect human health or property. Poorly maintained vehicles can produce 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 and diesel). Fuel use will emit greenhouse gases with about 2.3 to 2.7 kilograms of carbon dioxide equivalent (CO 2 -e) per litre of fuel consumed (DEWHA 2008). In addition, indirect and third party emissions will be generated as a result of energy used to produce materials (for example steel and concrete) – which is known as ‘embodied energy’. During operation, electricity will be required to power the facility, but the energy use will form only a small contribution to TfNSW’s overall greenhouse gas emissions. Control Measures Air quality impacts throughout construction will be minimised through a range of control measures 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 fitted emission controls are operating efficiently. Plant or machinery will not be left idling. Stockpiles will be maintained and contained appropriately, which could include covering or regular watering to minimise dust. Trucks transporting spoil and other waste materials from site will be covered appropriately. Page 34 of 72
Disturbed areas will be rehabilitated as soon as practicable. 4.4 Biodiversity Existing Situation Based on a search within a one kilometre buffer of the proposed site Location 1, there are 25 species of fauna, 8 species of flora, 11 migratory bird species and one endangered ecological community listed as threatened under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). Based on a search within a one kilometre buffer of the proposed site Location 2, there are 20 species of fauna, 8 species of flora, 15 migratory bird species and one endangered ecological community listed as threatened under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). These species or their habitat may occur in the search area (refer Appendix 3). Based on a search within a 10 kilometre buffer of the proposed sites, there are recordings of 58 threatened fauna species, 41 threatened flora species and 11 endangered ecological communities listed under the Threatened Species Conservation Act 1995 (TSC Act) within the search area (refer Appendix 3). The immediate area around the outdoor sites has been cleared previously. There are mature trees surrounding the two locations. RailCorp's Illawarra Vegetation Mapping Map 5 - Loftus to Port Kembla identified the threatened Sooty Owl approximately 400 metres from Location 2. RailCorp Sensitive Site Register identified native vegetation associated with Nature Reserves adjacent to the proposed locations. This has been identified as the Illawarra state conservation area. There are 90 species of noxious weeds identified in the Wollongong LGA. Weed control is enforceable by Wollongong Council, as the local control authority under the Noxious Weeds Act 1993. RailCorp vegetation mapping also indicates that Lantana, Crofton, and Turkey Rhubarb are found on the proposed site. Potential Impacts While there are several threatened species known to be present in the Wollongong LGA, the site is in a disturbed area adjacent to the rail corridor. Tree cutting or pruning is not required for this site, and all areas of new trenching are also located within cleared grassy areas. No native vegetation will be removed however grass will be cleared. The works are not expected to impact on listed threatened species or EECs. The Sooty Owl has been sighted approximately 400 metres from Location 2. No impacts on this species is expected as a result of the proposed work. Although there is dense vegetation surrounding the sites, the locations are within the railway corridor in an area previously disturbed, therefore it is unlikely that threatened fauna species will be present in the area.
