General 1.1 Reasons and Purpose for the Project Report 1.1.1 Necessity and reasons for the project construction Urban public transport is a crucial component of city transportation system, and public service including public transport plays an important role in the quality of life for citizens in the city. During the period of the "Ninth Five-Year Plan", the economy in Fuzhou City has growed rapidly, the urban city scale has been expanded, and the urban population has increased substantially, resulting in fundamental changes in demands in public transport. With the guidance of the policies of "Make a great change in three years" and "Give priority to public transport" of the municipal government of Fuzhou, the public transport sector starts a speedy improvement. However, planning and construction of the stations, maintaining yards, hub station, and the first and last bus stops of the public transport system lack integration and sufficiency. These factors restrict the further development and continued improvement of the public transport services. Therefore, the municipal government of Fuzhou has decided to increase the investment in upgrading the city's public transport system. Construction of Jinshan Central Bus Depot using a World Bank loan is one of the efforts to supplement for the public transport stations in downtown and the new city areas so as to improve the service and quality of public transport. The Jinshan Bus Depot project is located in Pushang Industrial Zone on the Nantai Island in the city's suburb. Opposite to Pushang Road is the planned Jinshan residential area, to the west is Jinshan Park, and to the north is a substation and Pushang long-distance bus station. In accordance with stipulations in Measures for Environmental Impact Assessment of People's Republic of China, State Council of PRC No. 253 Regulations on the Administration of Project Environmental Protection, and The World Bank Operational Manual- Environmental Assessment (OP4.01), environmental impact assessment must be carried out for projects. In June of 2004, authorized by Fuzhou Traffic Committee, Guangzhou Research Institute of Environmental Protection (Certificate No. of environment assessment: GHPZJZ 2802) undertakes the preparation of the Environmental Impact Assessment Statement of Jinshan Central Bits Depot of Fuzhou City. 1.1.2 Purpose of assessment The project will undoubtedly solve the increasingly serious problem of maintenance of buses in Fuzhou. However, whether the construction and operation period will harm the natural and social environment or not is under attention. This assessment aims at as per regulations and standards like Environmental Protection Law of People's Republic of China, carrying out investigation on the environmental quality status of atmosphere, sewage and noise etc. in the planned area of the project, analyzing the pollutants in the project, sufficiently understanding and objectively assessing impacts on the natural, social and economical environments and putting forward mitigation GRIEP and FREMS 6 March 200O  Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project measures of environment influence and plans for pollution control so as to realize the harmonious development of economic advancement and environmental protection in the construction and operation of the project, and to give full play to the benefits of the project. 1.2 Basis of EA (1) State Council No.253, Regulations on the Administration of Project Environmental Protection Nov., 1998;

On the basis of the first-hand investigation and survey of the project area, set up sampling locations of ambient air and noise for regular monitoring and experimental analysis. In combination with the monitoring data of the area in recent years, accurately determine the environmental quality status of the area. Adopt relevant mathematical models to carry out environmental impact assessment and bring forward corresponding measures for pollution control. 1.8 Selection of Assessment Factors As per the sewage features of projects, the following factors are selected for assessment: (1) Atmospheric environment: Status quo: PM,o, NO2; Impact forcast: NO2, hydrocarbon (not include C04), CO. (2) Sound environment: noise during construction and operation period (3) Water environment: for status quo, pH value, COD, BOD, DO, gasolineeum, and NH3-N 1.9 Classes of Assessment 1.9.1 Classification measures stipulated in OP4.01 of World Bank In accordance with the classification measures stipulated in The World Bank Operational Manual- Environmental Assessment (OP4.01), and as per the pollution characteristics of projects, source intensity of the pollutants and the environmental status of the project area, a comprehensive environmental assessment is required for the project construction of Jinshan Central Bus Depot of Fuzhou, which is classified as Category A. . 1.9.2 Classification of domestic environmental impact assessment Different from that of the World Bank, the environmental impact assessments in China as per the technical guidelines of environmental impact assessment in China are classified into three classes. Around Jinshan Central Bus Depot is an office building, employees' boarding house, maintenance yard, and gasolineeum and gas station. The sewages therefrom are respectively discharged into the oil traps and then into the municipal sewage pipe networks outside the station. The final destination of the sewages is Jinshan Sewage Treatment Plant, and the final reception water body is Beigang. The water environment of Beigang applies Category III standard of GB3838-2020 and the environmental impact assessment is determined as Class III. After the completion of the project, there will be a relatively little impact on the sensitive points of sound environment. As per the related regulations in Technical Guideline for Environmental Impact Assessment (sound environment) (HJ/T2.4 - 1995), the sound environmental impact assessment of GRIEP and FREMS 11 March 20t3  Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project the project is defined as Class III. According tQ the stipulations in Technical Guideline for Environmental Impact Assessment (ambient air) (HJ/T2.2 - 93), the air environment impact assessment is determined as Class III. GRIEP and FREMS 12 March 201  Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project 2 Project Description and Analysis 2.1 Overview of the Project 2.1.1 Project nature The project of Jinshan Central Bus Depot of Fuzhou is one of the World Bank financed projects in Fuzhou. The total investment therein is RMB 91,910,340 Yuan, 35% of which comes from the financing of the World Bank. 2.1.2 Location and land acquisition The project is located to the north of Pushang Industrial Zone, to the north is Pushang Road, to the east is the substation, to the south is Gaozhai and Geyu Village (including Hongjiang Road under planning) and to the east is Hongwan Road in plan. The specific location is shown in Fig. 2.1 - 1. The project will take up a total area of 12.288 hectares of various kinds of lands (including parts of the roads), among which, area of buildings is 42.15mu, pond area 3mu, nursery garden 104.19mu, and the others are grassland or empty area. 2.1.3 Contents and scale of the project The project of Jinshan Central Bus Depot, after completion, can hold 324 buses. It has a dispatching center of public transport, a junction station, a maintenance yard, gasolineeum and gas station, and employees' boarding houses etc. The project will be divided into two phases for construction. 2.1.3.1 Construction content in Phase I (1) The present public transport lines of the new area of Jinshan have 218 buses. And the newly-developed lines are 9 lines, with 176 added buses. The parking of these buses is urgent to be resolved. Therefore, the first task shall be the construction of public transport station, and the scale shall hold 200 buses. (2) Buses will feed gasolineeum or gas at least once a day, usually before parking at night or before starting in the morning. Therefore the gasolineeum and gas station shall be simultaneously constructed with the station. In order to avoid repeated investment and construction, it is better to finish the gasolineeum and gas station for only one time which can satisfy the supply for 300 buses both at night and in the daytime. Part of the station can be operated towards external businesses. (3) It is necessary to prepare a repair shop in the station of public transport for the repair of vehicles operating every day. The scale shall be adapted to the land scale of Phase I and the service condition. The floor plan of Phase I project is shown in Fig. 2.1-2. For the main economic indexes of Phase I project, see Table 2.1 -1. GRIEP and FREMS 13 March 20t  Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project Table 2.1-1 Economic Indexes of Phase I Project Quantity Unit (hectare) Total area of* land 4.34 Hectare acquisition Land of station (200 buses) 2.23 Hectare Land of repair shop 0.25 Hectare Land of gasolineeum and 0.54 Hectare gas station Office building of the gas 348 mr station Washing workshop 3 Set Afforestation area 0.41 Hectare 2.1.3.2 Construction content of Phase II (1) On the basis of Phase I project, properly extend the station in order to satisify the requirements of bus parking for the medium and long term of Jinshan new area. The scale shall be able to hold 300 buses. (2) With the development of the new area of Jinshan, and the increase of public transport lines, it is important to carry out supplementary construction of the first and last bus stops. For the present, there are only two initial and final stations in Jinshan Exhibition City and Industrial Zone. A majority of buses are parked along the road. In Pushang District, the Pushang Industrial Zone has been completed. Jinshan residential area to the north of Pushang Road is under development and construction. It is obvious that there will be a certain amount of passenger flows in the block in the next few years. Therefore, the construction of initial and final stations in combination with the station shall be carried out to meet the requirement of the passenger flows, and to balance the layout of the network of public transport lines. After completion of Pushang Bridge, the first and last bus stop shall be upgraded as a junction station in connection with the University City and the downtown area. 8 lines are planned for the station. (3) The key in Phase II project is to construct the elementary maintenance yard and repair shop in the station, so that the first and second maintenance of buses shall be completed in the station and meanwhile the repair work of 300 buses shall be finished in the station. (4) In 2010, there will be 2880 buses for public transport in Fuzhou. With the increase of buses and public transport lines in operation, the dispatching by man cannot meet the requirements. Therefore, the construction of a modernized dispatching and control center for public transport becomes urgent and will be beneficial to the promotion of service level and work efficiency of public transport as well as to the maintaining of sustainable development of city traffic. (5) In the station, build some boarding houses for the employees so as to provide a place for the drivers and stewards of the buses in wee hours to GRIEP and FREMS 14 March 20*4  Environtnental impact Assessment for Fuzhou Jinshan Central Bus Deport Project rest at night. (6) To eliminate the impact on the surrouding environment, it is required to increase the afforestation rate of the field in Phase II project.

In the junction station, there are altogether 100 shifts of the 8 lines every hour, thus there are 1900 buses/times/d coming into or leaving the bus depot. The running speed is 5hm/h, average idle speed time is 5min and the average running distance is 400m. Therefore, the average emission of air pollutants of each vehicle coming into and leaving the bus depot shall be calculated as per the following fornula: Si=(Eig E L+Iig - T) Fg+(Eid+Iid - T)Fd Thereinto, Eig is the comprehensive emission factor of heavy duty gasoline cars; lig is the emission factor of heavy duty gasoline cars at idle speed; Fg is the proportion of gasoline cars; Eid is the comprehensive emission factor of heavy duty diesel vehicles; Iid is the emission factor of heavy duty diesel vehicles at idle speed; and Fd is the proportion of diesel vehicles. The proportion of gasoline vehicles is 40% and that of the diesel vehicles is 60%. Therefore the average emission amounts of each vehicle entering and exiting the bus depot are: HC10.82g, CO 66.45g, and NOx 6.97g. The average emission of air pollutants in the bus depot is shown in Table 2.2-4. Suppose that the turnover vehicle flow at peak hours in the station is 100 buses/times/h, the source intensity of air pollutants in the station at peak hours is shown in Table 2.2-4.

In case of raining, those pollutants will be brought into the rivers with the rain. These are pollutants of non-point source pollution. In order to eliminate these kinds of pollutants, it is planned to collect the initial rain water in the first 1 5min for process in biochemical pond and then the rain water is discharged with other kinds of sewage. The pollutant parameters of water quality of the initial rain water in the maintenance yard are mainly BOD5, CODIr, gasolineeum and suspended matters etc. The production of initial rain water can be estimated as per the formula: Initial rain water discharge amount (t/d) = annual average quantity of precipitation in the project area (m) X runoff coefficient X gathering area (mi2) X 10%/annual precipitation days. The runoff coefficient is 0.8, the annual quantity of precipitation is 1354mm, the gathering area is 122,400m2, and the annual precipitation days are 150 days.
