LIST OF FIGURES Figure 21: Estimates of greenhouse gas emissions based on diesel consumption (plant and

mobile fleet) .................................................................................................................. 3

Figure 22: Australian annual per capita radiation dose from natural and medical sources (ARPANSA 2012) ......................................................................................................... 3

Figure 23: Location of planned hydrogeology test work for Ranger 3 Deeps ................................. 4

Figure 24: Predicted total suspended particulates deposition (blasting and diesel particulate) for alternate vent locations. Modelling is based on a single stope ventilated through a single exhaust point source........................................................................................... 4

Figure 25: Predicted total suspended particulates deposition (mg/m2) from a 10 m ventilation stack, combined blast and diesel (with pollution reduction technology) ......................... 5

Figure 26: Predicted fine particulate concentrations across a number of receptors. Note: Blast particulate size distribution is derived from US Environmental Protection Agency and National Pollution Inventory sources. Modelling is based on a single stope ventilated through a single exhaust. .............................................................................................. 5

Figure 27: Predicted 24-hour average radon concentration (mBq/m3) from a 10 m ventilation stack in and around the Ranger Project Area ......................................................................... 6

Figure 28: Potential pathways for transport of radionuclides into the environment ......................... 7

Figure 29: Location of groundwater monitoring sites (statutory monitoring sites shown in red) ...... 8

Figure 30: Magela catchment showing gauging stations ................................................................ 9

Figure 31: Current mine sub-catchments and water type. (NB: Pit 3 will become a process water catchment during transfer of tailing from the tailings dam during 2014-2020.) ............. 10

Figure 32: Dominant soil types in areas surrounding the Ranger operations based on a land mapping approach to define boundaries between soil types (modified from Hollingsworth 1999). (The proposed location of proposed Ranger 3 Deeps underground mine infrastructure within the Magela Land Application Area is shown in red.) ............................................................................................................................ 11

Figure 33: Ranger Project Area showing the extent of archaeological surveys and sites (unshaded)2 ................................................................................................................ 12
