ENVIRONMENTAL STANDARDS In FY18, IGO introduced a set of Environmental Standards. These standards define a performance expectation that is more than simple compliance with the law. Over time, and with ongoing effort, these standards will provide a framework for cultural change within our business. The standards address: • social and environmental impact assessment • land use and biodiversity management • water management • mineral waste management • hydrocarbon and chemical management • rehabilitation and mine closure. IGO’s Environmental Standards were developed based on relevant Australian and International standards, including the Leading Practice Sustainable Development Program (LPSDP) for the Mining Industry (Department of Industry, Innovation & Resources), and publications produced by the Minerals Council of Australia, and the International Council on Mining & Metals (ICMM). The standards were benchmarked against our peers and feedback from both our workforce and our host communities was also considered. In FY19, IGO will begin implementing the standards using our environmental risk register to determine priorities. The implementation program will be targeted at both our workforce and host communities to provide insight into the standards and ensure that they are refected in our operational management plans and our actions on site and in the community. TRANSPORT Both the consumables used at our mines and our products are transported by truck. Truck traffic within regional areas is a recurring matter of concern for the public. To this end, IGO seeks to minimise truck traffic, particularly through regional towns. Feedback received from our stakeholders is taken seriously and all complaints are investigated. During FY18, we received no complaints and we are pleased to note that we even received some positive feedback from a Norseman resident. The largest volume of trucks was recorded at our Nova Operation, averaging 50 per week. Truck transport reduced at Nova, compared with FY17, due to the operation transitioning from construction to steady state operations. Truck traffic at Tropicana was comparable to the previous year, averaging 40 trucks per week. The reduction seen in FY17, resulting from the power station switching from diesel to gas (supplied via pipeline), was maintained in FY18. The Jaguar Operation received 40 to 50 trucks per week, mostly travelling 900km from Perth to site, passing through several towns including Northam, Southern Cross, Kalgoorlie, Menzies and Leonora. Our contribution to the impacts created by vehicle movements through these towns is minimal. Lower production at our Long Operation further reduced truck deliveries to approximately 200 a year, the majority from Kalgoorlie, located 57km north. The trucks pass close to Kambalda east and west, however do not transit through the town’s residential areas. The area has been mined for more than 50 years, with no homes in the vicinity of our operation. As such the impact of dust and fuel emissions is minor. IGO tracks diesel usage at all our operations, with transport accounting for a significant portion of consumption at Long and Jaguar (see Figure 23 below). Nova’s power station is fuelled by diesel, with the bulk of its consumption accounted for in energy production rather than transport.
