Summary 1.1 Project background and retrospect of environmental assessment task Nanjing Iron & Steel Group Co.Ltd ( called NISCO for short) is started in 1958. After construction and modification for more than 40 years, NISCO has expended gradually and become a large scale steel corporation, ranking among provincial key enterprises and 520 state key-supported industrial companies as well, which possesses a complete production facilities of sintering, pelletization, coking, ironmaking, steelmaking and steel rolling ,with all matched utilities facilities. The production capacity of 1.8 million tons of iron, 2.4 million tons of steel and 2.1 million tons of rolled products has been formed. The output in 1999 is 1.5 million tons of iron, 1.77 million tons of steel and 1.66 million tons of rolled product, with sale value of 3.757 billion RMB yuan and tax & profit of 0.347 billion RMB yuan. Even though the steel capacity of NISCO has already reached 2.4 million tons, the production equipment and technological process are under the framework of small scale integrated steel enterprise which is setup during planned economic stage. Due to lower equipment capacity, back-wardness of technological process, the product is mainly based on commercial grade of carbon steel and construction grade which has less value-added feature. In addition, market competiveness is not sharp due to lower labor productivity, higher energy consumption, higher production cost and poor economic efficiency. The problem of environmental pollution exists as well. In order to meet the need of national economic construction and NISCO `s development, NISCO urgently needs adjustment of technological process and product mix. NISCO has long time experience of production of plate. The ship plate has already acquired works approval from 8 shipping classification societies. The proposed modern Steckel mill adopts Steckel mill technology of producing plate from coiling process, which is different from traditional discrete plate production. It has the advantage of increase of yield, improvement of quality , less cost, more market competiveness and remarkable economica benefit compared with traditional plate mill. After abolition of the existing technology and devices, NISCO will make its contribution to improve the quality of environment in Dachang District via adjustment of product mix and improvement of pollution treatment measure. In order to start the project, Jiangsu Provincial Planning and Economical Committee has submitted to the National Planning Committee on Application of Prefeasibility Study of NISCO Wide Plate/ Coil Project with annualcapacity of 1 million tons. The National Planning Committee has approved the projection application on 20 Dec. 2000. Nanjing Municipal Environment Bureau and Jiangsu Provincial Environment Bureau has approved the projection application after assessment of Application Table on Environment impact of the proposed Project submitted by NISCO. As per the requirement in the regulation of Constructiive Project Environmental Protection Control, Environment Department of NISCO entrusted Beijing Environmental Assessment United Company to execute enviromental assessment of Wide Plate/ Coil Project of NISCO, and asked Nanjing Municipal Environmental Protection Scientific & Reserach Institute to render support. After site exploitation and data collection, and based on the principle of cleaning production, pollution discharging meeting standard, new project advancing exsiting facillities and polluant PAGE 5 OF 283  ENVIRONMENT IMPACT REPORT total amount control, and environmental assessment guidance, the assessment company compiled Environmental impact Outline of Wide Plate/ Coil Project. National Environment General Bureau sponsored review on the above mentioned Environmental Impact Outline on 21 Sep. 2000, and gave approval on 13 Oct 2000 of reply to Review of Environmental Impact Outline of Wide Plate/ Coil Project of NISCO , with Doc. Release No. 162 (2000) on Envorinmental Supervision. Based on the environmental impact outline and reply to review from authorities, the environmental assessment company completed the Environmental Impact Report of Wide Plate/ Coil Project of NISCO. During assessment progress, we received a lot of support from National Enviromental General Bureau, Environmental Assessment Center, Environmental Office of National Metallurgical Bureau, Jiangsu Environmental Protection Bureau, Nanjing Municipal Environmental Protection Bureau, NISCO's Enviornmental Protection Department and Planning Department. Hereby we express our thanks to all parties invloved. 1.2 Evidence 1.2.1 Environmental protection law, regulation and control document (1) Environmental Protection Law of P.R.China (Release Dec 1989)
