In order to get rid of the current traffic problem and prevent future traffic crisis, the municipal government absorbed successful experiences on solving traffic problems from domestic and abroad big cities, and determined to vigorously develop a public transit with rail transit being backbone and ground traffic being major means of transportation, thus study and planning for rail transit come to consideration. Nanchang City Planning (2001-2010) involves the planning of construction of 5 rail transit lines and puts forward the implementation plan of construction of line 1 and Line 2 project within the planning period. In January 2008, based on Notice on Strengthening Construction and Management of Urban Rail Rapid Transit of the General Office of the State Council (GBF [2003] No. 81), Nanchang has entrusted Shanghai City Comprehensive Transportation Planning Institute with The Plan of Nanchang Urban Rail Transit Network. In July 2008, the planning was completed and was approved by people’s government of Nanchang in file HFTZ (2008) No. 163. The network planning scheme involves 5 lines with total length being 167.7km, and there will be two comprehensive vehicle bases, two periodically repair sections and three parking lots. The plan is to construct Line1 phase 1 project and Line 2project between 2009 and 2016, and construct the X-shaped skeleton network composed of Line 1 phase 1 and Line 2 phase 2 in 2016. We will construct Line3 and the second phase of Line 1 and Line 2 between 2016 and 2020, and form the rail transit skeleton network composed of Line 1, Line 2 and Line 3 by 2020. The whole network will be gradually completed from 2020 to the vision years. According to the network planning revision, Shanghai Tunnel Engineering and Rail Transit Design and Research Institute and Shanghai City Comprehensive Transportation Planning Institute co-compiled the Nanchang Urban Rail Rapid Transit Construction Planning (2009-2016); in July 2009, the planning was approved by National Development and Reform Commission in FGJC (2009) No. 1978 Notice 4 on Printing and Distributing the Reply of NDRC on Immediate Nanchang Urban Rail Transit Construction Planning (2008-2016) (attachment). According to the planning, a rail transit project with length being 50.6km will be built from 2009 to 2016, which includes line 1 phase 1 project and Line 2 project. Of which, The total length of Nanchang Rail Transit Line 2 Project will be about 23.78km, and there will be 21 stations which will all be underground stations with average station spacing being about 1.09km. The whole line is set with a comprehensive base which locates at southwest of South Avenue Station. The project is from Nanchang West Railway Station to Xinjiaan Station, the route will go through the west railway station planning area, the Hongjiaozhou district, the Honggutan new district, the center of the old town and the eastern district of the city, and it will connect the Nanchang west railway station, the International Sports Center, the College Town of Honggutan, the Nanchang Central Business District, Yangming Road, Bayi Square, Nanchang Railway Station and some other passenger hubs, which not only connects the core areas of old town and new town, but also covers the most important area of south-north corridor between Changnan old town and Changbei new town. In February 2010, Nanchang Rail Transit Co., Ltd entrusted Guangzhou Metro Design and Research Institute Co., Ltd with compilation of Nanchang Rail Transit Line 2 Project Feasibility Study Report (February,2010), which is also the design consideration for Environmental Impact report.

Thus in addition to calculating investment and expenses for controlling pollution, the possible environmental and economic effects shall be accounted during analysis of economic gains and losses due to environmental impact. 6.2.1 Means of Assessment and Analysis The economic gains and losses due to environmental impacts of the project are comprehensively assessed by means of static analysis method, and conclusion is drawn from environmental and economic perspectives. (1)Net Benefits of Environmental Protection Investment Calculation of net benefits of environmental protection investment is intended to assess the dominant environmental impacts of the project(beneficial or adverse impacts). The calculation formula is as follows: B 总=(B 措-K)+B 工–L �: As shown in the formula：B 总: Net benefits of environmental protection investment; B 措: Environmental economic benefits produced by environmental protection investment; K : Environmental protection investment and expenses; B 工: Environmenal and economic benefits due to environmental impacts of the project; L � : Environmental and economic lossed in case of no environmental protection funds (2)Investment Efficiency Ratio in Environmental Protection The benefits and expenses ratio of investment on environmental protection must be calculated to assess the rationality of investment on environmental protection, and feasibility of environmental protection. The calculation formula is as follows: E 总=(B 措+B 工–L �)/K In case E 总≥1, it shows that the environmental economic benefits of the project are larger than the environmental protection expenses, and the project is accpetab le. In case E 总<1, it shows the environmental protection expenses of the project is larger 124 than the benefits obtained, and the project shall be given up. The larger E 总 is, the better effect of environmental protection investment will be. (3) Ratio between Environmental Protection Investment and Capital Construction Investment Comparison of the index with that of similar domestic projects can confirm the rationality of the project. 6.2.2 Analysis of Economic Gains an Losses due to Environmental Impacts The economic gains and losses due to environmental impacts of the project are comprehensively assessed by means of static analysis method, and conclusion is drawn from environmental and economic perspectives. (I) Major Factors Influencing Environment The major factors influencing environment entered into analysis of economic gains and losses due to environmental impacts are noise, ecological landscape and water pollution etc. according to characteristics of the project and specific local environmental conditions: (II) Environmental economic losses produced before input of environmental protection funds L � (1) Environmental economic losses caused by noise: L �声 According to the characteristics of the project, the populations around the air kiosk, cooling tower and depots as well as the ground lines of entrance/exit depot will be influenced by noise to various extents. Thus the project mainly assesses the environmental economic losses caused to surrounding populations due to subway noise. The report has selected the assessment coefficiency for environmental and economic lossed caused by noise of rail transit in Germany to passengers adopted by Planco in 1992 in a similar case, i.e. RMB 1.2 yuan per 100 persons km. Suppose the average running speed of the train is 35km per hour(daily operational hour: 18 hours). As rail transit is a rapid means of transport, if the short interval between the trains is omitted, the trains running on the route can be seen as continuous, and the social populations around the noise source will receive constant impacts by the noise. And such people are influenced by the noise as if they travel by subway at 35km per hour for 18 years. It is estimated 9397 persons will be influenced by the noise of the project, and L �声 is 22 million yuan per year. (2) Environmental economic losses(L �水) caused by water pollution: If the sewage discharged by the project is directly discharged without being disposed, the receiving water body will be polluted, and environmental economic losses will be caused due to deterioration of water quality. Such environmental economic losses is approximately replaced by the sewage discharge expenses payable for discharge of sewage of the same water quality and quantity. According to the current charging standards and provisions of relevant department, in case the sewage produced by the project is directly discharged without being disposed, the construction unit will pay 150,000 yuan per year as the sewage discharge expenses. Thus L �水 is 150,000 yuan 125 per year. (3)Total environmental and economic losses(L � ) caused before input of environmental protection funds: Environmental and economic losses caused before input of environmental protection funds: L �= L �声+ L �水=22.15 Million yuan per year (III) Investment on Environmental Protection K The investment on environmental protection of the project is 131644000 yuan, which will be amortized over 4.25 years. Thus K is 30,975,100 yuan. (IV)Environmental economic benefits(B 措) caused by investment on environmental protection: (1)Environmental economic benefits(B 措声) caused due to decrease in the number of people influenced by noise after noise control According to the prediction results for impacts on sound environment, the noise level at the sensitive points along the project line is basically maintained at the level before project construction after noise and pollution prevention and control measures are taken, that is the project construction will not increase the noise level of various sensitive points. B 措声 is 22 million yuan per year. (2) Environmental economic benefits(B 措水) caused by control of water pollution: According to relevant provisions, the sewage of the project will be discharged after reaching standard through treatment. The sewage discharge fee in the amount of 30,000 yuan per year shall be paid after sewage treatment through calculation, and 150,000 yuan per year shall be paid before sewage treatment. Thus the environmental economic benefits produced through treatment of water pollution(B 措水 ) is 120,000 yuan per year. (3) Total environmental economic losses produced by investment on environmental protection(B 措): B 措= B 措声 + B 措房 + B 措水 =22.12 Million yuan per year (V) Environmental economic benefits caused by engineering environmental impacts(B 工): The extent of environmental pollution will be different in case road traffic instead of rail transit is adopted to meet the ever increasing demands for traffic by economic and social development along the route of the project in Nanchang City. (1)Comparison of Environmental Economic Losses due to Noise Pollution: To compare the environmental economic losses casued by noise due to two means of transport, the function of road traffic shall be the same as that of the means of transport of the project, and the travelling speed per hour is 35km per hour, with the daily operational period being 18 hours and the same quantity of passengers. Moreover, as road traffic is totally on the ground, the number of people influenced by 126 noise on the two sides of the traffil route will be larger than that of subway, and is estimated to be 24,000. The populations along the road are influenced by noise as if they travel by road at the speed of 35km per hour for 18 hours. According to relevant data of Germany, the estimation coefficient for environmental economic losses caused by road traffic noise on the passengers is RMB 1.7 yuan per 100 persons km. The environmental economic losses caused by road traffic noise(L 路声) is 80 million yuan per year through calculation. The environmental economic benefits(B 工声) caused by noise pollution in the two ways is B 工声= L 路声- L �声=80 Million yuan per year. (2)Comparison of Environmental Economic Losses due to Atmospheric Pollution: As rail transit utilizes power as energy, it produces less atmospheric pollution, thus the environmental economic losses caused by its atmospheric pollution is approximately 0. According to the conclusion of atmospheric environmental impact assessment, the emission of automobile exhaust will be reduced due to project construction. The environmental economic losses due to road atmospheric pollution is estimated according to the environmental economic losses caused by the road traffic exhaust on passengers in Germany, that is RMB 0.2 yuan per 100 persons km. B 工气=9.8 Million yuan per Year. (3)Total environmental economic benefits(B 工) due to engineering environmental impacts: B 工= B 工声 + B 工气 =89.8 Million yuan Per Year (VI) Analysis of Economic Gains and Losses due to Environmental Impacts: (1) In case B 总 is larger than 0, it shows the environmental impacts of the project are mainly beneficial. Net benefits from environmental protection investment B 总 =(B 措 -K)+B 工 -L � =58,294,900 yuan per year. (2) Environmental protection investment efficiency E 总=(B 措+B 工-L �)/K=2.92 E 总>1, which shows that the environmental economic benefits of the project is larger than the environmental protection expenses, and the environmental protection investment effect is good. (3)Environmental protection investment/capital construction investment ratio: The environmental protection investment of the project is 132444000 yuan, and the estimated total investment of the project is 14846032400 yuan, thus the environmental protection investment/capital construction investment is 0.89%, which is similar to that of the environmental protection investment of similar domestic project. Thus the environmental protection investment is rational. 127 6.2.3 Conclusion: The completion and operation of the project will positively promote social economy and urban environment in areas along the routes of the project. The environmental economic losses caused by project construction will be controlled within a small scope after several environmental protection measures are taken. Project construction will produce significant social benefits and environmental benefits, which complies with the principle of simultaneous growth of economic benefits, social benefits and environmental benefits. 6.3 Sources of funds According to the current financial strength of Nanchang, the capital of Nanchang rail transit Line 2 project to be considered the mode of direct government investment, Adopted government financial sources of funding are: government budget funds for construction, special funds for urban construction(with civil air defense special funds) and Land transfer revenue and so on. Debt funds are mainly considered loans of domestic bank and World Bank. 7 Information management of the Environmental and Social Management Plan 7.1 Reorganize and save of monitoring data The monitoring information involved in this project is reorganized by qualified units commissioned by Nanchang track Limited. 7.2 Information exchange Environmental management requires the necessary exchange of information between different departments and different positions within the organization, at the same time, the organization also need communicate relevant information to the outside (stakeholders, public and so on). Internal information exchange can be carried out in a variety of ways of meeting and internal briefings, but a formal meeting must be hold monthly, all exchange of information should be recorded and archived. External information exchanges is held once every six months or one year, the exchange of information with collaboration unit should be formed the minutes and archived. 7.3 Record For the effective operation of the environmental management system, the owners must be organized to establish a sound system of record, and retain the records of the following aspects: (1) Legal and regulatory requirements; (2) Related review and approval to the project; (3) Environmental factors and the related environmental impact; 128 (4) Training; (5) Examination, checking and maintenance activities; (6) Monitoring data; (7) Problems in environmental management and environmental protection work; (8) Mitigation measures effectiveness; (9) Relevant project information.
