The overall objectives for environmental management are outlined in the Environment Policy. Table 7 provides a summary of objectives for a number of key environmental areas. Table 7 - Environmental Objectives Issue Goal Objectives Air To maintain current air quality standards. To comply with air quality criteria as listed in the Project Approval and EP Licence, as verified by monitoring. To implement air quality control measures as outlined in the Air Quality Management Plan. To receive minimal community complaints, which are addressed promptly and satisfactorily, and reported as required. To report and address any non-compliances. Lead To have no adverse impact on blood lead levels of the community. To assist the community in raising awareness about managing lead in the environment. To use measures to minimise dust emissions. To support community blood lead level monitoring programs. Noise To maintain an acceptable noise amenity for surrounding neighbours. To use measures to minimise noise emissions. To monitor and meet noise emission criteria and EP Licence conditions. To promptly address any complaints relating to noise from the general public and report as required. To report and address any non-compliances. Water To prevent pollution and contamination to surrounding lands. To use measures to prevent water discharge. To reduce the risk of oil or chemical contamination of surface / groundwater. To reduce sediment runoff. Emergency response To quickly and effectively minimise adverse impacts to the environment associated with an emergency situation. To provide training and equipment to enable a quick and effective response to environmental emergencies including spillages. Heritage To retain the maximum possible value of cultural mining heritage located on CML7. To prevent demolition wherever possible of listed heritage buildings and structures. To adaptively reuse heritage buildings where possible. To conserve heritage buildings and structures where possible. Management of Key Environmental Risks
unsealed roads. Service roads and tip points around the ROM stockpile will be laid with compacted road base. Installation of vehicle wash facilities for all vehicles that have entered the mine site. Limitation of vehicles in exposed ‘free’ areas. Undertaking sampling to quantify road surface silt loadings on an ongoing basis. Use of street sweeper. Concentrate Maintaining a moisture content level around 9 percent. Concentrate loading operations Installation of vehicle wash facilities for all vehicle and container prior to delivery to rail loading/storage area. Conveyors Full enclosure of all conveyors and transfer points prior to the milling circuit. Tailing storage There will be a number of levels of dust management at the tailing storage facilities including: embankments to be constructed with waste rock which is moisture conditioned prior to placement and water sprays during placement water sprays to be installed along the roadway during the movement of waste rock the moisture content of the tailing and cycling frequency between cells the use of chemical dust suppressants1 water sprinkler system water truck Video equipment will be installed at TSF2 when the tailing level increases to a level where there is potential dust generation from the Pit. This provide continuous surveillance in the control room for operators. ‘Free areas’ The use of chemical dust suppressants1. Maintenance of surface crust to minimise potential for wind erosion. Limitation of work access to ‘free’ areas. Removal of fine material, particularly in water storage basins, or capping with waste rock. Greenhouse gases Complete energy audit to compare predicted and actual energy consumption by 31 December 2011. Note1 Where a different chemical dust suppressant is used than those included in the EAR BHOP will conduct a new health assessment and forward this to Greater Western Area Health Service and NSW Health for approval prior to its use. Community Lead Measures Consistent with the Project Approval BHOP will continue to contribute to a Lead Awareness and Impact Management Strategy developed in consultation with the Lead Reference Group, including the NSW Department of Health (Greater Western Area Health Service) and BHCC. BHOP has prepared a Community Lead Management Plan for the Project which outlines measures to prevent adverse health impacts to the local community. The Plan also outlines BHOP contribution to the public health monitoring program, particularly in relation to child blood lead levels, and tracking of this data over time; and to public education campaigns about the
