6.0 Electricity supply Power supply for the site office and other amenities will be sourced from TNB grid line. EMPIRE.CO has two power stations which are located near the processing plant and other main buildings such main office, cafeteria and laboratory. The power consumption for each amenities will affect the tariff electricity of the mine. The tariff electricity for mining industry is categorized under low, medium and high voltage. Table 6 below shows the tariff for industrial and mining in Malaysia. Table 6: Tariff category and current rate for mining 6.1 Water supply The primary main water supply is obtained from Syarikat Air Darul Aman (SADA) . It is mainly used for main buildings such as office, toilet and other purposes. However for mine operations, the source of water is obtained from the tailing pond when the sediment is trapped at bottom layer and left the layer of water at the top. Water from sedimentation may be used for drilling purpose and rehabilitation process. Water supply is also used in controlling the dust at quarry area such as road spraying and wet dust suppression system. The purpose of road spraying is to control dust emissions. Dust produced during mining is a leading contributor to environmental pollution and can effect employees’ health. The purpose of using water sprays and mists to control fugitive dust on piles, roads and crushing plant. Therefore, in order to control dust in quarrying operations, a large amount of water is required. Water consumption in the mine is shown in Table 6.1 as follows: Table 6.1: Water Consumption in EMPIRE.CO The estimated water consumption in the quarry is estimated about RM 28,000 per year. It is calculated based on water tariff from Syarikat Air Darul Aman as shown in Table 6.2 Table 6.2: Water Tariff for industrial purpose in Kedah state Huge amount of water is also required for processing plant. Therefore, the water from nearby river will be pumped into the water tank to support the capacity of water needed. Water that is discharged from the processing plant will be flow into the tailing pond and for filtration. After that, the water will be reused back for processing plant operation. The pond also will be provided to collect the storm water for reuse. This will ensure that the rainwater is effectively used and minimizes the drawl of ground water resources.
