SEE EXECUTIVE SUMMARY The Syerston Nickel Cobalt Project (the Project) is owned by Ivanplats Syerston Pty Limited (IVP). This Statement of Environmental Effects (SEE) is provided to support the application to modify the original Project Development Consent under Section 96(2) of the Environmental Planning and Assessment Act 1979 (EP&A Act). The proposed modification arises predominantly as a consequence of proposed changes in the rate of ore processing from 2.3 million tonnes per annum (Mtpa) to approximately 2.5 Mtpa (acid pressure leach autoclave feed rate), and removing the refinery section of the processing plant. This results in some changes, including: • simplification of the metallurgical processing plant; • change in the product mix from metal and mixed sulphide to just mixed sulphide; • increase in the production of mixed nickel and cobalt sulphide; • reduced number of process consumables used and changes to consumable quantities; • changes in some processing air emissions; • a reduction in power consumption; • change in the number of transport movements from the Rail Siding and Limestone Quarry (Quarry); • increased production rate from the Quarry; and • a reduction in the operational workforce. Environmental reviews that have been conducted to evaluate the Project modification proposal have concluded the following: • From an operational noise perspective, a specialist review has concluded that the proposed modification to the Quarry design would result in no additional significant noise impacts beyond those assessed in the approved, consented Project Environmental Impact Statement (EIS). • From an air quality perspective, a specialist review has concluded that as a result of the proposed Project modifications at the Mine and Processing Facility (MPF) and Quarry, no residences are likely to experience dust deposition or emission concentration levels above the current Department of Environment and Conservation (DEC) assessment criteria. • From a traffic perspective, a specialist review has concluded that the management measures detailed in the EIS and Development Consent would remain unchanged and applicable to the modified Project. • The proposed modification would involve an approximate additional 53 hectares (ha) of land disturbance at the Quarry. IVP is required to implement management procedures for stripping, stockpiling and re-using soil resources in its progressive rehabilitation programme as part of the original Project Development Consent. • The additional material to be placed on the Quarry waste emplacement would have similar geological and geochemical characteristics to the waste rock generated by the approved Project, and is therefore not predicted to alter the potential impacts described in the EIS. May 2005 ES-1 Syerston Nickel Cobalt Project - SEE • Due to the screening effect of local ridgelines and vegetation screens, the number of publicly accessible roads and privately owned residences from which views of the Quarry would be available would remain substantially the same as those described in the EIS. For the privately owned residences which do have views of the Quarry, the visual impact of the proposed modification is predicted to be substantially the same as documented in the EIS due to the distances involved, screening effects of the local topography, and implementation of management measures required by the Development Consent. • From a flora perspective, through the application of Eight Part Tests of Significance, no threatened flora species, populations, ecological communities, or their habitats would be significantly affected by the Project modification proposal to the extent that the viability of a species, population, ecological community, or their habitats would be undermined. • From a fauna perspective, through the application of Eight Part Tests of Significance, no threatened fauna species, populations, ecological communities, or their habitats would be significantly affected by the proposal to the extent of undermining the viability of a species, population, ecological community, or their habitats. • Potential surface water and groundwater impacts for the modified Project are expected to be similar to those predicted for the approved Project.
