Matrix of prediction and evaluation of Envoronmental Impact vii INITIAL ENVIRONMENTAL EXAMINATIONS FOR THE CONSTRUCTION OF A 150 XV HIGH VOLTAGE TRANSMISSION LINE BETWEEN MULUT TANEANG POWER PLANT AND CEWPAXAAND TRISAXTI SUBSTATIONS CHAPTERI INTRODUCTION I.1. Background Electricity demand is very,high in Indonesia, and is increasing. Within the past ten years, the average increase has reached 15 t per year. Power Plants need to be built to meet this demand. Usually, the location of the generating plant can not be close to the center of the load area, because the primary resources needed for the power station (e.g. water power, geothermal) are not removable. Also secondary resources (such as cooling water for a steam energy power plant) are not available anywhere else. For these reasons transmission lineb are required to transmit the electricity from the power plant to the load area. The electricity demand for the State Electrical Company Sub district VI in South Kalimantan is projected to reach 800 NW by the year bf 2015. To meet this demand, construc- tion of a Steam Energy Electric Power Station with a GGO MW capacity will begin in 1995. The Mulut Tambang Power Plant will be located at Asam Asam, a town in Sub district Jorong, Regency Tanah Laut. In order to transmit the electricity from tilhe ulut Tambang Power Plant, a 150 XV high voltage transmission line will be constructed. The line from the Mulut Tambang rower Plant to the Cempaka Substation will be 75 km long and the I- 1 line between Cempaka and the Trisakti Substation will be 43 km long. X. 2. Legislation Some legislation related to the Construction Planning of the 150 XV High Voltage Transmission line between the Mulut Tambang Power Plant and the Cempaka and Trisakti Relay Stations are as follows : 1. Legislation No. 20/1961, concerning about revocation of ownership right of Land and other properties in it. 2. Legislation No. 4/1982, about main regulations on tha environmental management. 3. Legislation No. 15/1986, about power plants (electrical energy). 4. The Government Regulation No. 34/1979, about electricity exertion. 5. The Government Regulation No. 29/1986, about environmen- tal impact assessment. 6. The Instruction of the President of the Republic of Indonesia No. 9/1973, about implementation of the revoc.j tion of ownership right of land and other properties in it. 7. The Minister of Internal Affair Regulation No. 15/1975, concerning about Provisions of Land acquittal procedures. 8. The Decision of the Minister of Residential Affairs and Environment No. 50/Men KLH/6/1987, about the Guide lines oi Compilation of Environmental Impact Assessment, Enclosure I. 9. The Decision of the Minister of Hining and Energy tao. 0935/K/008/M, about technical guide lines for initial envi- ronmental examination compilation for steam energy pcwer plan project. 10. The Decision of the Minister of Residentiai Attairz ana Environment No. 49/I4enKLH/6/1987,about Important Impact I - 2 Determination Guide Lines and its Enclosures. 11. The Regulation of the Minister of Mining ana Energy No. Ol/P/47/MPE/1992, concerning about the Minimum Free Distance between High Voltage Transmission Conductor and the Ground and other object. 1.3. Purposes and Objectives The transmission line is 118 km long and will pass through the Regency Banjarmasin, Administrative city Banjar Baru, and Regency Tanah Laut.
