Where possible, all new and replacement infrastructure installed onsite should be coloured the same colour as the existing infrastructure and therefore remain visually recessive in this established and contained industrial context. 10.0 Tailings Storage Facility 3 As part of this project, the construction of an additional tailings storage facility is referred to as TSF3. This extends east of and adjoins the existing tailings storage facilities along the toe of a more elevated backdrop to the north and east. Once completed, TSF3 will accommodate an additional volume of approximately 5.7 million cubic metres, extending approximately 46 metres above existing ground level to an elevation of 155 masl. Construction of tailings storage facilities is a gradual sequential process rather than a development which occurs simultaneously and all at once. At completion the final surface will be established in pasture and appear integrated within the existing broader tailings storage facilities. 62 Effects during implementation before mitigation 63 Effects During Operation with Mitigation (5-10 years) 64 Residual Effects at Completion following mitigation 65 Level of Effect assessed as: Very High, High, Moderate-High, Moderate, Moderate-Low, Low, Very Low 66 Nature of Effect assessed as: Adverse, Neutral or Beneficial
