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. The floor plan of Phase II project is shown in Fig. 2.1-3. Refer to Table 2.1-2 for the main economic indexes of 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.

Gas cooker units are to be installed in the eatery. Oil gas is planned to be used. There are two cooking stoves with a smoke emission of 2000m3/h. To be calculated as 3 hours of operation per day, the smoke emission from the eatery will be 12000m3/d. 2.2.3.3 Analysis of main water pollutants 1) Main souces of drainage out of the bus depot: a. Sewage from washing the vehicles in the washing workshop; GRIEP and FREMS 18 March 20O Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project b.

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.

As per Table 2.2-5, sewage in need of pre-treatment is the oily sewage from the maintenance and repair workshop, and the quantity thereof is 240. 1m3/d. 2.2.3.4 Noise source The noise of this project mainly comes from the spare generator room, the air GRIEP and FREMS 20 March 209 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project compressor plant, and operation of machine in maintenance and repair shop as well as the noises of the public buses. The levels of the noises from various sources are: generator 105 1 lOdB(A), air compressor75 - 85dB(A), machines and equipment 80-90dB(A), and the public buses 79'82dB(A). Noises in the construction period mainly come from the construction machinery and the noise value thereof is 86- 112dB(A). 2.2.3.5 Solid waste The solid waste of this project is mainly the production waste residue in the bus depot and the domestic garbage of the workers. The production waste residue, to be calculated as per 10kg for each maintenance vehicle, 38 vehicles per day, will be about 0.38t/d, and will be 138.7t per year; the domestic garbage, to be calculated as per 0.5kg/person/d, will be 0.05t/d and 18.25t per year. 2.2.4 Hazard analysis of the gasolineeum and gas station 2.2.4.1 Function and scale of the gasolineeum and gas station Oil tanks and gas tanks are to be installed in the gasolineeum and gas station, supplying gasoline, diesel and CNG. There will also be automatic weighing devices. Therefore the station can admit the operations of gasolineeum or gas filling of several vehicles simultaneously. (1) Physical property of the stored oil 90# Lead-free gasoline Flammable liquid, colorless to light yellow, with a special odor, highly volatile; relative density 0.8, boiling point 37.8°C, relative density of the gas 3.0, insoluble in the water, lead content<0.013g/l, sulfur content<0.15g/l; flash point -43°C -23C, self-ignition point2800C, explosive rangel.4-7.6%, poisonous, narcotic in case of inhalation of high density. Gasoline is classified as Item I, Class I dangerous material of flammable liquid with low flash point in harzardous degrees stipulated by the state, the serial number is 3001. Diesel Light green, transparent liquid, degree of color< No.2, with a special odour, insoluble in water, flammable, if meet with heat source, open fire or strong oxidizer, easy to be lighted; relative density 0.85, melting point -29.560C, boiling point 180,370°C, and flash point 400C. Gas density 4, gas pressure 4.OkPa, flammable limits of the mixture of air and the gas 0.7-5.0%, the residue carbon in the 10% residual oil below 0.3%, cetane number above 45, sulfur content300'-500ppm, and nitrogen content I0- 100ppm. (2) Physical property of CNG GRIEP and FREMS 21 March 2O03 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project The main component of CNG is the hydrocarbon in paraffin, composed of CH4(82%-98%), a little C2H6, C3H8, and C4H,o. CNG is a kind of complex hydrocarbon CnHm. CH4 has a good capability in anti detonation, and the RON of it can achieve 130. C2116, C3H8, and C4H10, with a bad antidetonation quality, will reduce the antidetonation capacity of CNG. However, the contents of them are low, thus the influence is minimum. Therefore, the antidetonation capacity of CNG is much better than that of gasoline. CNG used for vehicles is strictly restricted by some technological standards and requirements. It is required to dewater, purify, and unmix the CNG so as to remove the unsatisfactory components like sulfur, sulfide, water and heavy hydrocarbon etc. Vehicle-use CNG after processing shall be a kind of high quality, highly efficient and clean substitute fuel material. The ignition temperature of CNG in constant pressure is 600-650°C, while that of the gasoline is 380-450°C, and that of the diesel is 260-350°C. Whether the mixture of CNG and air is easy to be lighted depends on the ratio of air and CNG and the components of CNG. Compared with gasoline, CNG has a relative stronger energy in ignition. 2.2.4.2 Hazard analysis (1) Hazard analysis of pollution of soil and groundwater by the oil in the gasolineeum station There are mainly two kinds of instances i.e. surface leakage/spills and underground leakage in most oil leakage accidents in gasoline and CNG stations. Surface leakage is mainly leakage of tank car for oil transportation, leakage of oil pump in oil discharge, leakage because vehicles collide with the equipment in the station, leakage of failure of filling equipment and during the repair work, and small quantity of leakage in the process of filling in the vehicles. Underground leakage is mainly the leakage of the buried oil tanks and oil pipeline because of chemical erosion, leakage because of stretching and breaking of pipelines for changes of geocondition, or leakage caused by improper grounding buildings, and the stress of running vehicles. There are various measures for prevention of oil leakage, such as constructing sealing up tunnel, sealing up wall to the groundwater level, laying rubber anti seepage isolation layer, or setting concrete or 4 in 1 soil isolation layers etc. (2) Hazard analysis of CNG leakage There are mainly four kinds of accidents in CNG station, fire; explosion and leakage; explosion after fire; and fire after explosion. Each of the four will cause serious results. Therefore it is important to take precautions to prevent the occurrence. GRIEP and FREMS 22 March 200O Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project 3. Baseline Environmental Condition of Project Area 3.1 Natural Environment 3.1.1 Location Jinshan Central Bus Depot is located at the southwest part of Nantai Island to the southeast of Pushang Road and Hongwan Road. To its east is Pushang Industrial Zone. The area of the project was once belonging to the newly-built Geyu Village and Gaozhai Village and as such the west and the south to the project are areas for residences of the villagers. In the middle area and to the east are nursery gardens and farmlands. The specific location is shown in Figure 2.1-1. To the east of the proposed bus depot site is a substation, and site for a proposed Pushang long-distance passenger bus station; to the south is Hongjiang Road in planning, and across road are the residential areas of the new Geyu Village and Gaozhai Village; to the west is Hongwan Road in planning, across the road is the area for the planned extension of Jinshan Park; to the north is Pushang Road. 3.1.2 Geological and topographical features The general topographical patterns of the location from the west to the east are medium mountain, low mountain, high hill, low hill, mesa plain and then the sea, which are regularly arranged. The surface relief descends as per layers. The field belongs to Geyu Village and Gaozhai Village. To the south is the residential areas of the villagers, to the east are nursery gardens and farmlands etc., and to the north and the west are roads. The surface relief descends from the southwest to northeast. And the ground elevation is 4.6-5.6m above the sea. There are three high voltage towers and some electric power facilities in the field, which are difficult to be removed during the construction. 3.1.3 Weather and climate At low latitude, and close to the ocean, Fuzhou has a subtropical marine climate. Because of the impact of the seasonal exchange of the cold and warm drafts, the seasons are distinct without extreme cold days in winter generally nor intense heat in summer. It has an abundant precipitation with an annual quantity of 1,354 mm. The precipitation in summer takes up 37% of the total quantity. The area has abundant sunshine. In spring, the weather changes a lot while in autumn, it is relatively stable. The wind is mainly southeaster, and then comes the northwester and north wind. There is seldom northeaster. The maximum wind speed in the year is 14-17m/s. In typhonic seasons, the instant maximum wind speed can reach 42m/s. The frost-free period is as long as 328 days. According to statistics of data in the 39 years from 1951 to 1989 by the weather station of Fuzhou, the annual temperature of Fuzhou is 1 6-20°C; the GRIEP and FREMS 23 March 2043 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project extreme high temperature is 41 C. The average temperature in July is 28.80C, the maximum temperature difference in the daytime is 17.3°C (that is on July 21, 1982), and the average temperature difference in July is 14.6°C. The average temperature in January is 100C and the extreme low temperature is -2.5 C. According to the statistical data of the weather station of Fuzhou, the leading wind direction in the year is southeaster, with a frequency of 14.3%, the secondary leading wind direction in summer is south wind, and in winter is northwester. The frequency of calm wind throughout the year is 20%. The annual average wind speed is 2.9m/s and the maximum wind speed is 31.7m/s. From the middle ten days of July to the last ten days of September is the .yphonic period, the occurrence of typhoon in which takes up 80% of the year round. Influenced by the typhoon, the average maximum wind speed and extreme high speed can achieve Level 12; the wind direction is northeast. The. most serious typhoon (No. 6112) in September 12, 1961 landed in Jinjiang at 14:00, with the extreme high speed of 45m/s and the maximum speed of 40m/s. Apart from the typhoon, the winds caused by disasters like storm and hail etc. can reach the speed of 24 - 30m/s. Around the project area is mainly southeaster, with the wind power of Level 5-6. Fuzhou is subtropical marine monsoon climate in south Asia. The sunshine hours for the whole year thereof are 1968.6h. The average precipitation quantity for many years is 1342.5mm. The distribution of precipitation is uneven in terms of time and space. The precipitation thereof is mainly divided into four periods, March-April spring rain period, May-June bai-u rainy period; July-September typhoon and storm period, and October- next Febuary the brief rain period. Precipitation in bai-u rainy period takes up 32.2% of the whole year while precipitation in the flood season from April to June takes up 73.7%. The average relative humidity of Fuzhou in March-June reaches 80%-84%, that of October to next January is 71%-74%, and that in July to September and in February is 76%-78%. The annual average relative humidity is 77%. The absolute humidity averages 19mm every year. 3.1.4 Hydrological geology The groundwater along the line is mainly pore water, fissure water and pore crack water. Pore water distributes in (©) Littoral plain. Because the quaternary system is quite thick in deposition, it usually has 1-2 water-bearing layers, which compose pore groundwater or confined water. The groundwater elevation is commonly 0.5-3.0m. The confined water layer, as per the depth of the water layer in different sectors, has a water production of 1-I OL/s. The water quality thereof is complicated. ( The grit and pebbles in the alluvium and dilluvium of the quatemary system absorb the atmospheric sedimentation or the side gain from the river; this layer is rich in water and the water level varies a lot with the seasons. GRIEP and FREMS 24 March 200O Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project Fissure water is rich in the bedrock joint fissure or the fracture zone, the replenish source of which is atmospheric precipitation; and the water level of which is seldom influenced by the seasonal variation. The fissure water is always ejected in the form of spring at the low cavity with a large quantity. Pore crack water is always distributed at the bottom of cracked slope lamination and bedrock weathered zone. This kind of groundwater is mainly replenished by atmospheric precipitation and the water content is minimum. 3.1.5 Soil Geologically, in this location is fine sand with a depth of 30m; on the earth surface is sedentary clay soil: isabelline, castable if hard, saturated if wet, mainly fine textured soil, with few sand grains. Some is sedentary mastic clay soil: mauve or glaucous, mainly fine textured soil with sand grains. 3.1.6 Water basin and hydrologic general conditions Minjiang River originates from Wuyi Mountain, Xianxia Mountain and Shanling Mountain etc. at the junction of the three provinces of Fujian, Zhejiang and Jiangxi. From the northwest to the southeast, it flows across Nanping, Fuzhou and enters the East Sea in Mawei. The river is 581km long, and its basin area is 60,992km2, which almost one half of the area of Fujian Province. It is the biggest river in the whole province. The downstream of Minjiang River splits into two branches respectively in the south and north. The south branch is called Nangang (or Wulong River) and the north branch is called Beigang (also called Minjiang River). Beigang flows across the urban area of Fuzhou City, and then converges with the south branch Wulong River in Mawei Economic Development Zone. The converged river enters Hekou section, goes by Tingtou and splits into two branches of the south and north again. The two branches respectively flow into the sea by Meihua and Changmen. Nangang is about 27.5km from the diffluence pass of Huai'an to Wulongjiang Bridge. Its watercourse is wide and shallow. The flow path is wandering as the channel of flood discharge and sediment ejection. In the drainage area of Minjiang River, the precipitation is abundant, and the volume of runoff is large. From April to June, it is mainly frontal precipitation, while from July to September, it is always typhoon rain. The above two kinds of rain are the mainly precipitation patterns. The water in the drainage area of Minjiang River mainly comes from the flood of the three branches in the upstream (Jianxi River, Futun River and Shaxi River). From the analysis of the historic observation data, the three branches do not combine with the branches of Nangang. Wulong River locates at the tidal river section in the downstream of Minjiang River. Because of its special geological location, the river encounters flood from the upstream and tide in the downstream. The south tide at the exit of Minjiang River influences Nangang, Beigang and even the branch of Zhuqi of Minjiang River. As per analysis of the measured peak flow, for the current diversion ratio of GRIEP and FREMS 25 March 200 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project the volume of flow of Nangang and Beigang, at low water time, the volume of Beigang accounts for more than 70% of the total volume. In flood time, the volume of Nangang takes up more than 70% of the total. The general trend is with the increase of volume, the diversion ratio of Beigang decreases. 3.1.7 Seismic general condition According to Plaitning Graphic of Division of the Seismic Intensitv in Clhina, the seismic intensity of this project area is Degree VII seismic zone. Located at the north section of the southeast seismic belt along the coast, i.e. the faulted basin of the quaternary system in Fuzhou, the project field is an active structural basin, the controlled fracture of which is grid pattern fracture structure. The fracture is several km - tens of kilometers. And the width is several meters to more than ten meters. The adjacent area of the field has no symptom of movement since Holocene. 3.2 Baseline Socio-economic Conditions in Fuzhou 3.2.1 Urban characteristics In accordance with General Urban Planning of Fuzhou 1995 - 2010, the urban character of Fuzhou is defined as the capital city of Fujian Province, a national historical and cultural city (publicized in the second batch), an important economic center in the southeast area along the coast of our country, and a modern port city. 3.2.2 Geological position Fuzhou is situated in the junction point of the sea routes and airlines of the Asian districts with economic development at a high speed, the center of the highly opened zone along the coast of our country, the central point of the developed districts between the Yangtze Delta and Zhujiang Delta. The district advantage of Fuzhou is obvious. What's more, the airport, important infrastructures like harbour, the main arteries in the south and north direction along the coast (highways) and railway etc. further strengthen the advantages of this location. Nantai Island, situated at the west and south parts of the downtown area, has convenient traffic conditions in waterway, landway and airway. On the island, there are beautiful mountains, verdant trees, which endow the island with abundant natural and cultural sights. More than 60 universities, colleges, secondary schools and research institutes locate in Cangshan District, thus the district is the most important education and scientific and technological research base. Cangshan District of Nantai Island is developed in economy, and has formed Cangshan Scientific and Technological Park and Cangshan Industrial Zone etc. In 2001, the industrial output thereof was RMB 450,000,000 Yuan. There have been industrial bases Jinshan Investment Zone, Gaishan Investment Zone and Chengmen Investment Zone in Nantai Island, thus the island now is a significant area of urban construction and investment in Fuzhou, and will play an important role in the development of this century: for one, as a new growing point of the urban area in Fuzhou, and the new city GRIEP and FREMS 26 March 200O Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project area, it takes on a task in expanding the city scale and increasing the economic output; for the other, it has to share the functions of Gutai District in dispelling the population and traffic burden of the city and in promoting the development of the city into a virtuous circle. 3.2.3 Socio-economic Baseline of Fuzhou City and Nantai Island 3.2.3.1 Population and community Fuzhou city implements a system to bring along the development of counties by cities. It has five districts, two cities and six counties under its jurisdiction, namely five districts of Gulou District, Taijiang Disctrict, Jin'an District, Cangshan District, and Mawei District, two cities of Fuqing City and Changle City, six counties of Minhou County, Lianjiang County, Luoyuan County, Minqing County, Yongtai County and Pingtan County. Up to the end of 2001, there are 1726,200 households, and a permanent population of 5,941,400, among which 1,537,700 are the urban population (of the five districts). Nantai Island is situated in the south part of Fuzhou downtown area. After the adjustment of the district division of Fuzhou urban area, Cangshan District extends to include the whole Nantai Island, with five towns namely Jianxin Town, Gaishan Town, Chengmen Town, Cangshan Town and Luozhou Town, 35 community residents' committees, 36 residents' committees, and 112 administrative villages under its jurisdiction. The total area is 142km2. 3.2.3.2 Development and utilization of land resources in Nantai Island Nantai Island is diversified in land patterns, and rich in land resources. There are altogether 142km2 in the whole district. The maximum land use rate in this district is in Cangshan Town, 99.27% and the minimum land use rate is in Chengmen Town, 90.17%. In the developed land area of this district, the agricultural land, including farmland, gardens, forest land, grassland and culturable water area etc. is 7896.33hectares, accounting for 59.7%, most of which is in Jianxin Town; non agricultural land, including residential area, industrial and mineral area, traffic land and non culturable water area etc. 5330.47 hectares, accounting for 40.3%, most of which is in Cangshan Town. Thereinto, gardens take up a maximum proportion of agricultural land (41.7%), then comes the culturable water area, 32%. The unused land area is 980.83hectares, accounting for 6.9% of the total, 78.38% of which is uneven ground 768.78 hectares, 12.25% of which is pathes between fields, 120.1 Ihectares, and 5.94% of which is bare ground, 58.23hectares. The other land patterns occupy a minimum area and proportion. The sequence of unused land areas from the more to the less are Chengmen Town, Jianxin Town and Gaishan Town. 3.2.3.3 Economic development Since the reform and opening up, the national economy and social cause of Fuzhou have been developed to a large extent, with the comprehensive strength of the city ranking the top 10 capital cities in the whole country. In 1984, Fuzhou was announced as a national historical and cultural city in the GRIEP and FREMS 27 March 20OY Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project second batch, and one of the 14 port cities opening to the outside world along the coast; in 1985, it was listed as one of the comprehensive experimental cities of the national reform of economic system; in 1990, it became one of the 35 cities with GDP over RMB 10,000,000,000 Yuan. In 1991, it ranked the first "top 50 cities of comprehensive strength in China" and the 40 excellent cities in investment hard environment; in 1997, the comprehensive strength ranked 24 among the 219 cities above the level of district; and in 2001, the economic total output of the city ranked 9th, which was 17th in 1978 among the 26 capital cities. Fuzhou City successively won the title of "National Excellent City in Civilization Construction" and "National Hygenic City", for three times was awarded with "National Excellent City in Science and Education Promoting the City Development", for four times continuously won the title of "National Model City for Mutual Support between the Civilian and the Arm Forces", and in 2000, it was selected as one of "Chinese Outstanding Tourism Cities" with a high score and high quality. In 2001, the GDP of the city achieved RMB 107,423,000,00OYuan, 9.4% more than that of the last year. Thereinto, the increase of the first industry is RMB 13,264,000,000 Yuan, that of the second industry is RMB 50,563,000,00OYuan, and that of the third industry is RMB 43,596,000,000 Yuan. Up to the end of the year 2001, there are altogether 1,726,200 households, with a permanent population of 5,941,400 (the natural increase rate of population is 0.486%). Therefore, the GDP per capita is RMB 18,034 Yuan, which growed 8.4% from the last year. 3.2.3.4 Natural scenery of the city Fuzhou is one of the outstanding tourism cities of China, and also is a tourism city with unique characteristics. As early as the Song Dynasty, the city of Fuzhou was covered with banyan trees. People didn't need to use covers in summer. Thus the city got a name of "Banyan City". Yushan Mountain, Wushan Mountain and Pingshan Mountain with fascination and beauty in the city make Fuzhou become a unique city of "Mountains and Urban Area are interweaved". Futhermore, with Wuta Pagoda and White Pagoda of a history of more than 1000 years, and Minjiang River (Nangang) with an annual volume of 60billion m3 running across the city area, the unique scenery of "Three mountains, two pagodas and one river" with a rich historical and cultural charm was formed. What's more, Gushan Mountain and Xichan Temple in this city are world renowned. Gushan Mountain, with Yongquan Temple as its center, has more than 160 scenic spots in the four directions of east, west, south and north. Furthermore, the city has North National Forest Park, Qishan Scenic Spot etc. 3.2.3.5 Development and utilization of groundwater resources Minjiang River has an average annual flow of 56.1 billion m3 for many years. The average river depth of the section in Fuzhou is 500-1500 mm. The average river depth in the downtown area is 680 mm. The annual water volume generated from the city area surface runoff is estimated 26,000,000 m3, and that is 1,954 m3 per person. However, since there is a large amount of GRIEP and FREMS 28 March 2005 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Depon Project water inflow from upstream to the city area through Minjiang River, the freshwater resource is abundant in Fuzhou. The water amount per capita is as much as 12,500 m3, ranked the second of the 14 opened cities along the coast. At present, Cangshan district has several water supply plants including Chengmen Water Plant, Yixu Water Plant, and Nanqu Water Plant. The water supply of Chengmen Water Plant is 60,000 t/d, that of Yixu Water Plant is 21,000 t/d, ad that of Nanqu Water Plant is 30,000-40,000 t/d. The city has got some small water plants in various industrial zone, or enterprises. It is estimated that the annual water supply can amount to 48,000,000 tons. 3.2.3.6 Cultural relics and historic sites Surrounded by rivers, Nantai Island has a nice climate. With mountains and waters on the island, it has unique natural, historic and cultural sceneries. There are many traditional historic sites and cultural relics reserved in the area. Jianxin Town, where the project is to be located, has municipal a few cultural relics and historic sites including Jinshan Temple, Xiangshu Ancient Temple, Yupin Country Villa, Chendong Martyry, General's Temple, Jianxin Miaofeng Temple, Longjiang Temple etc. There is no protected cultural relic on and immediately around the projectsite. The Zudian Temple, located at Fenggang village is anrdinary temple constructed by the villagers with no particular cultural, historical and religionous values and as such it is not in any protected list of governnents. There is no regular or formal religionous service at the temple although villagers from Fenggang and other nearby villages go causually for worship irregularly. This temple is located near the Jinshan Bus Depot site and could potentially be affected by the project implementation particularly during the construction phase. But since most of the construction activities are quite some distances away from the temple, the most direct impacts from dust and noise of construction activities would be in a short period of time, estimated to be one to two weeks during fence wall construction. 3.3 Master Planning of Fuzhou City 3.3.1 Development Objectives of Fuzhou City In ten years of construction and development from 2001 to 2010, Fuzhou City will be built into a modem international metropolis with complete infrastructures and perfect comprehensive functions, with the speed of highways accelerated, the railway electrified, ports automated, and airport internationalized, coordinatively forming a complete and convenient set of comprehensive transportation system integrating highway, railway, harbour, and international airport, as well as a expedite modernized communication network. Up till 2010, its national economic strength will be strengthened largely, approaching or achieving the average level of the medium developed countries or regions in Asia. It will become a modernized international metropolis as the commercial center, the communication and traffic center, the scientific and technological information center, the education and culture center and the GRIEP and FREMS 29 March 20O9 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project economic and business center of the two sides of the Taiwan Straits, with informationalized management and highly efficient operation radiating the whole province and the adjacent provinces and cities and connected with the international market. The economic and social development strategic objective in the next 20 years of Fuzhou will be realized all-around. 3.3.2 Development Scale of Fuzhou City As per the O( erall Plannzing of Fuzhou City, the general arrangement of the urban area is: with the areas along the river and along the coast as the axis of development, set up central city and ten satellite towns along Minjiang River, Wulong River and the coast, which are interconnected with expedite and convenient traffic, and thus form a "L" spatial structure of modem metropolis with the central city as the core surrounded by the ten satellite towns. For the construction of the central city, the leading direction is "extend to the east, advance to the south and exploit to the west". The key point is to develop Nantai Island across the river, especially the new Jinshan District and the University City. The layout of the central city is a group layout structure which takes 817 Road as the traditional central axis, and the modem development axes of Minjiang River as the skeleton, Gutai District as the core area, surrounded by the 6 closely connected but independently developing districts of Gushan District, Xindian District, Cangshan District, Jinshan District, Gaishan District and Jianxin District. The following table shows the population and land scale of the near-term and long-term central city and the six subdistricts.

The orientation of the commercial and business center among the four functions is to concentrate on the development of various special wholesale markets and storage markets; for the tourism, the key point is to develop sight-seeing and traveling. (2) General structure and scale On the basis of the urban planning of the central city determined in the general planning of Fuzhou, and as per the new planned scale, the island is divided into 5 sub-districts of Jinshan District, Jianxin District, Cangshan District, Gaishan District and Chengmen District according to the group structure pattern. In 2005, the planned population is 413,440, in 2010, the planned population is 538,200, and in 2020, the planned population is 800,000. The functions and scales of the sub-districts (till 2020) are shown in the following table. Table 3.3-2 Functions and Scales of the Sub-districts of Nantai Island Planned Population Function sub-districts (10,000) Jinshan 16.66 Top grade residential area, cultural District and educational district Jianxin 16.76 Cultural and educational district, District residential area Cangshan 22.17 Central area, cultural and District educational district Gaishan 14.24 High-tech park District Chengmen 10.17 High-tech park, tourism and District recreation district Total 80 GRIEP and FREMS 31 March 20& Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project 3.3.4 Functional Zoning (1) City center and the commercial and business district There are one center and four sub central areas for the central system of the whole island. The center locates at the position between the Liberty Bridge of Nanjiangbin Road, and the three bridges on Minjiang River, and the place beside Nantai Road. The four sub central areas are the four sub-districts of Jianshan District, Jianxin District, Gaishan District and Chengmen District. The commercial and business central district is within the scope of Shangshan Road, 61 South Road and Nantai Road, with an area of 6.7 hectares. (2) Tourism and recreational district Along the line of the south of Luozhou and Chengmen by the river, in combination with the tourism project development along the river, and making use of the abundant natural and cultural sceneries, construct a cultural and tourism belt along the river. (3) High-tech industry district Based on Cangshan Scientific and Technological Zone, Gaishan Investment Zone and Chengmen Investment Zone, further expand the area, optimize the structure, and build a high-tech industry district. The planned area for the new industrial park is 713 hectares, including 113 hectares in Puxiazhou, 53 hectares of Cangshan Scientific and Technological Park, 133 hectares of Gaishan Investment Zone, 120 hectares of Guo7hai, 100 hectares of Luxia, and 127 hectares of Panyu. (4) Cultural and educational district Consummate Shoushan Cultural and Educational District, develop Feifengshan Cultural and Educational District, maintain Huai'an and Luozhou cultural and educational districts, in this way, intensify the function of Nantai Island as the cultural, educational, scientific and technological base of Fuzhou City. (5) Top grade residential area The residential areas are mainly in Jinshan District and Jianxin District. In Jinshan District, there are mainly top grade residences, especially along the line of Wulong River and Minjiang River are almost garden residential areas and some villas; in Jianxin District, there are mainly economical residences or other common residential buildings. As a whole, the construction of the new districts shall abide by relatively high standards. (6) Ecological industrial park of Jianshan District It is located to the north of Jinshan Road, and to the south of Xishan Mountain, and is divided into the west block, the central block and the east block by GRIEP and FREMS 32 March 208 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project Hongwan Road and Jianxin Street. The total land area is 360.73hectares. (7) Planning of land use apart from the city construction The total area of Nantai Island is 142 kM2, some is used for the city construction. The others shall be used for the development of high quality agriculture and sight-seeing agriculture (the land for airport is not included). 3.4 Baseline and Development of Municipal Transportation System The development goal of municipal economy and traffic shall be based on acceptability of society, sustainability of environment and feasibility of execution. 3.4.1 Status and problems of road traffic in Fuzhou City In 2001, the total length of roads in urban areas of Fuzhou was 912km, including main roads with a total area of 10,195,000m2 and an average area of roads owned by each person up to 6.63 m2. In 2002, the operating income of public transport industry in Fuzhou was RMB304,514,300 Yuan, with the passenger capacity of 307,676,710 and running distance of 108,960,000km, increasing respectively 7.87%, 12.19% and 103.31% from the last year. 11.32 public transportation vehicles which is a scalar have been owned by per ten thousand persons; there are 89 operating lines including 37 lines for minibus. The line network covers 1,348km and the length of lines for minibus is 544.1km. The length of the line network is 367km, 109.8km of which is for minibus. There are 4,120 bus stops with an occupied area of 221,700m2. With the acceleration of urbanization progress, the frequency of people's going out is continuously rising and the total amount is also continually increasing. Meanwhile the quantity of motor vehicles in Fuzhou has rapidly increased after China's entry into WTO. Especially since 2002 application for license plate has been decontrolled, the quantity of motor vehicles in urban areas has rapidly increased. As per statistics, from October of 2001 to October of 2002, almost 20,000 motor vehicles in urban areas of Fuzhou have been increased in less than one year. On the other hand, the municipal road construction of urban areas has been carried out steadily, however in recent years the growth rate of distance of newly-built roads is not up to 5%, much less than the growth rate of quantity of motor vehicles. Therefore, the conflict between traffic demand and supply becomes increasingly acute, which makes the city roads problems worse. The road traffic environment of urban areas has gradually become worse and there are traffic jams on some main intersections and main roads. The city traffic has affected the normal operation of city and restricted the rapid development of economy, so it needs to be settled. In general, the main problems about city traffic status in Fuzhou are as following: 1) The structure and layout of road network are not proper, strong in the north and weak in the south specifically; the structure of road network in new urban areas is comparatively complete while the road network in old urban GRIEP and FREMS 33 March 20O3 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project areas needs to be mitigated; 2) Gradation of road network is inconsistent, in details: no high-speed road network, better main network, big break on sub-roads, broken ends and narrowness of branch roads awaiting to be reconstructed and completed; 3) The construction of public bus depots lags behind and the roadside parking lacks of normalized management; 4) Excessive, over-narrowness and abnormity of intersections and interweaving, mixing and randomness of motor vehicles, non-motor-driven vehicles and pedestrians lack of mitigation and cause traffic jams to road traffic of Fuzhou. All these above problems are acute, not only needed to be mitigated rapidly for the moment starting from management, but also needed to be settled basically based upon status and setting about long term. 3.4.2 The goal of transport development Establish perfect structural system of city traffic and match city roads at all levels and form a comprehensive rapid and convenient traffic system which can meet the long-term requirements of city traffic and harmonize with social economy and human and ecological environment, with reasonable layout, definite functions, higher construction level and modem management level, multiple levels, multiple modes and in accordance with the agreement. The layout of road network in Fuzhou makes establishment of main roads network as frame, with modem road network which is reasonable and can meet the traffic demands. As per Comprehensive Urban Traffic Planning in Fuzhou made in 1995, the city road network in Fuzhou is in the form of square grid plus circle radial including 8 roads radiating outwards, 3 ring roads and many main roads extending from east to west and from south to north. The city high-speed road network is composed of the 2nd and 3rd Ring Road, special road for airports, expressways (connecting line), Guohuo Road and Pushang Road on Nantai Island etc. The Inner Ring Road surrounds the core zone of city, from Ximen in the north, Baima Road over Minjiang River to the south, connecting with Shangshan Road and Shancha Street and South Liuyi Road to the east, Liuyi Road over Minjiang River connecting with Hudong Road at Dongmen, connecting with Hubing Road to the west, and then back to Ximen. Since the inner ring road is located in the old urban areas, crossing downtown areas with most sections reconstructed from old roads and extension of roads is involved in Three Archways and Seven Lanes (cultural relics and showplaces)with difficult harmony, so it is planned as Class I Urban Main Road of the city. The 2nd Ring Road surrounds the outer ring of Inner Ring Road, from the West of the North Ring Road in the north, passing Tongpan and Xiangshan through Yangqiao Road and Gongye Road, along Changting Road over Minjiang River (Youxizhou Bridge over Minjiang River) to Jianxin, northern Gaogai Mountain connecting with South Liuyi Road (Nantai Road) in planning to the east, further reaching Baihuting to the east, turn to the north along South GRIEP and FREMS 34 March 208 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project Lianjiang Road, passing Aofeng Bridge connecting with Jiangzhong and Beilu through Wuliting, No.2 Chemincal Co., Ltd, Jinjishan Tunnel, intersecting North Liuyi Road and North Wusi Road to Beihuan Road. The total length of 2nd Ring Road is 28.5km with a Class I Main Road of about 18km established and is planned to be constructed as per high-speed standard before or after the year of 2010. By the end of 2002, through multiple demonstrations of municipal CPC committee and municipal government, comprehensively considering the factors such as environmental protection, sights, traffic and cost etc., it is determined that the construction of overhead high-speed road above the 2nd Ring Road shall be postponed. The Outer Ring Road (3rd Ring Road) is planned as high-speed road with 6 lanes through some new districts such as Gushan, Xindian, Jinshan, Jianxin, Gaishan and Chengmen, which is the express channel between blocks of the new districts, outer ring line and radial roads will resolve the high-speed traffic and part of through traffic between urban areas and all satellite cities. The total length of the 3rd Ring Road which will be completed before 2020 is about 49km. These three ring roads play different roles in organizing city traffic: * The Inner Ring Road mainly bears the traffic flow of CBD. * The 2nd Ring Road mainly links subareas distributed at the outer of core zone together. * Except for Gaishan and Xindian, the 3rd Ring Road covers the whole . central city. The construction will be helpful to the establishment of road network frame with complete functions and reasonable structure and greatly make full use of the functions of existent roads to make most roads in urban areas convenient for the traffic lines extending outward and improve the benefit in scale of road network. As per Comprehensive Planning of Nantai Island in Fuzhou made in 2000, recently Huandao Road along the both sides of Minjiang River and Wulong River will be gradually constructed on Nantai Island. Take development of travel resource along rivers as a chance, promote the development of the land along rivers and accelerate the urbanization process of unestablished zones. Baseline and Development Plan of Transportation System in Fuzhou Since the reform and open policy has been implemented, great achievements have been made in social economy and city construction of Fuzhou, however, the city traffic problems become more and more serious. The slow increase of roads cannot meet the requirement of rapid increase of motor vehicles, so the conflict between demand and supply becomes more and more acute and the traffic environment of urban areas gradually worsens. According to Overall Urban Planning of Fuzhou City, the general layout of urban areas is as following: taking areas along the rivers and the coast as main development axis, distribute a center city and 10 satellite cities along Minjiiang River, Wulong River and the sea where convenient traffic with high speed is available. A spatial pattern of modern city appearing Type "L" with a central GRIEP and FREMS 35 March 20& Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project city as center and 10 satellite cities as surroundings has come into being. The existent road network of urban areas (North Minjiang River) is basically in the form of square grid while the road network of Cangshan (Nantai Island) appears the layout of free state and the main lines hasn't still formed a system. Since the New Century, the construction of urban areas takes "Expanding Eastward, Progressing Southward and Developing Westward" as the dominant direction, puts emphasis on development of Nantai Island and University City. The layout of central city adopts the group layout taking traditional central axis of Road 817 and modem development axis of Minjiang River as frame and Gutai District as the core, six districts i.e. Gushan, Xindian, Cangshan, Jinshan, Gaishan and Jianxin as outer surrounding closely and developing independently. 3.4.3 General Analysis of Public Transport 3.4.8.1 Review of development of public transport in Fuzhou Fuzhou Public transport General Company, with a history of 47 years, was founded on Jan.l, 1952. With the support of Municipal CPC Committee and Municipal Government of Fuzhou, in rencent years great development of public transport has been achieved in Fuzhou. Till the end of 2002, General Company owns 1,472 vehicles, 94 lines with a total length of 1,349km and a network length of 404km, 4,859 staff, 116 ticket check points, 12 junction centers and 3,148 bus stops including 70 concrete platforms and 132 stainless steel platforms. There are 9 sub-companies subordinated to General Company. Company One, Two and Three are the main force to carry passengers in urban and suburban areas. Company Four undertakes long distance transportation from Fuzhou to Guangzhou and Shenzhen. Since Minibus Company was founded in October of 1993, it has been developed into a Class II Legal Unit with 401 minibuses and 31 lines. The advantages of small size and flexibility of minibuses have been made full use and urban areas and Xincun Community have been linked together, which are popular among residents of Xincun Community. Sanshan Trade Company, advertisement companies, fittings for motor vehicles companies and overhauling factories, as per the range of business, carry on business such as external commodity trade, advertisements on carriages and platforms, fittings for motor vehicles and overhauling, medium repair and minor repair. In order to adapt to the demands of reform and open in Fuzhou, a foreign capital of 160,000,000 Yuan has been introduced by General Company since 1996. In addition, a capital of more than 20,000,000 Yuan has been raised through collecting money from staff and accepting donation from industrial and commercial enterprises of society to purchase more than 400 vehicles with air conditioners and develop and rebuild 21 old lines, thus the level of buses in Fuzhou becomes higher. 3.4.8.2 Key issues with of public transport system The construction of stations is always the weak link of public transport GRIEP and FREMS 36 March 20§ Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project development in Fuzhou, which has limited the further development of public transport and seriously affected the normal operation of city roads. (1) Lag of Station Construction In the past years the construction of public transport lags seriously behind and the infrastructure of public transport lacks of investment. Since 1995, there is no appropriation from government so that Jinshan Parking Area, Xiayuan Bus depot, Kuai'an Bus depot and Houban Overhauling Factory planned to be constructed during the period of "the Eighth Five-Year Plan" become umcomplete projects. At present, about 50% (700) vehicles have no bus depot to park and guaranteed repair, only being parked at roadside. Some fleets temporarily lease yard for parking and maintenance. At the first and last bus stop of some buses, there are no bus depots, even no station houses. In some newly-built residents'communities such as Jinshan Community, the planning and construction of the first and last stop of buses lag behind so that the traveling of residents is difficult. In some areas, the layout of newly-developed lines will have to be extended and diversed for the impact of land use of the first and last bus stop, which will have an effect on the service range of public transport. For those stations, which is provided by some cooperative units, especially developers of real estate, will be for free to public transport department at the beginning for their own benefits, but the situation is not pleasant later. (2) Unreasonable Layout of Stations For historical reasons, buses on part of routes to suburb in Fuzhou are always parked in the center of city such as Wuyi Square at Nanmen and Taijiang etc. and the land for parking cannot be ensured, which is unfavorable for organization of traffic in the center of city, so its location must be optimized. In addition, as per the survey of traveling by bus, residents are not satisfied with discommodious change caused by unreasonable location of bus stops, especially the routes and stations with a large amount of passenger flow volume, for example Taijing Square is without land for bus stations. Airports, railway stations, long distance bus stations, passenger transport dock etc. seriously lack of corresponding hub stations for buses making the change of passengers inconvenient. 3.4.8.3 Plan of public transport (1) Plan of Public transport of Central City in Fuzhou The Plan of Public transport of Central City in Fuzhou made by Shanghai Municipal Traffic Comprehensive Research Institute, Construction Committee and Planning Bureau of Fuzhou and Fuzhou Public transport General Company raises the development goal for recent and long term of public transport in Fuzhou City.

Thereinto, Jianxin Bus depot is also the object of this feasibility research with planned land of 38,000 m2 and maintainability of 190 vehicles. (2) Plan of Bus depot of Central City in Fuzhou The Plan of Public transport of Central City in Fuzhou in Fuzhou has presented the basic thought and initial ideas for layout and land scale of bus station, but has not confirmed the range of land use and execution plan. Plan of public transport approved has arranged the route network of buses and bus stations and planned the land for use, while not considering the range (control) of land use for bus stations and arrangement of bus stations in outer new zones and the general scale and systematical planning (control of land use) of bus stations. So Plan of Bus depot of Central City in Fuzhou has made detailed feasible plan of land use to ensure the land use of municipal public transport facilities. Combined with Plan of Public transport in Fuzhou City and the scale required by bus stations in all the districts, considering the overall planning of Fuzhou City and detailed plan of sub-districts, this Plan predicts the area of land use for maintenance (parking) required by the sub-districts of Fuzhou. The planned bus depots include Jianxin Bus depot, Xiushan Bus depot, Bus depot at South 2nd Ring Road, Bus depot in Fuxing Development Zone, Bus depot in University City, Xiayuan Bus depot, Wenshanli Bus depot and Kuai'an Bus depot at Mawei, with total area of 275,000 m2 and a capacity of 1,400 parked and maintained vehicles. GRIEP and FREMS 38 March 205 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project Thereinto, the planned area of land use for Jianxin Bus depot is 40,000 m2 and the parking and maintaining capacity is 200 vehicles. 3.5 Sensitive Receptors Surrounding Proposed Bus Depot The bus depot is close to Pushang Industrial Zone located at southeast of junction of Pushang Road and proposed Hongwan Road with an area of 183.6 mu (lmu=0.0667 hectares). In the bus depot, there is an office of Cangshan Jianxin Economic Management Zone, villagers' houses, farmland and high-voltage wires. Fig. 3.5-1, a photo taken from the air, the tower of high-voltage wires can be seen. Sensitive receptors around bus station: (1) South bus depot is close to Gaozhai and Geyu Villages and there are 32 houses within 4- 13 m away from the boundary of bus station. For detail, see Figure 3.5-2. Noise and waste gas produced in construction period and operation period will have an impact on these residents. (2) Zhuzhen Fenggang Ancestor Temple lies to the west of proposed bus depot. According to knowledgeable elderlies in the viallge, this temple was first built in hole of Geyu Village more than one thousand years ago. By 1914 (the 3rd year of the Republic), the whole temple had been rebuilt and extended. Since the Temple has been weathered for the hundred years, a new rebuilding was completed in recent years. This Temple, located between the proposed Hongwan Road and the proposed Bus depot. There is no formal service although it is used for religious activities of villagers. As it does not have partilular cultural, religious or historical values, the temple is not under protection lists of any levels of governments. As the proposed bus depot site boundary will be 10 m away from this Temple, it is not considered as a directly impacted recetpor. (3) There are some houses to the west of bus depot, located at the planned Hongwan Road and expanded Jinshan Park, not being considered as sensitive points. Therefore, the sensitive points near bus depot mainly distribute at the south of bus depot.

The exact locations of monitoring points are shown in Fig. 4.2-1. GRIEP and FREMS 42 March 209 Environmental Impact Assessment for Fuzhou Jirnshan Central Bus Deport Project 4.2.3 Monitoring time From Nov. 10 to Nov. 1 1, 2004, each sampling locations shall be monitored for two days, for both daytime and nighttime noise monitoring on each day. 4.2.4 Assessment standard of sound environment status As per relevant regulations of Environmental Planning of Urban Areas in Fuzhou city, the functional zones within the range of sound environment assessment are mainly classified as Category II and Category IV and sound environment quality shall be in accordance with the standard of Category II and Category IV stipulated in GB3096-93. Thereinto, the west and north of Jinshan Central Bus Depot, are roads, western and northern areas belong to Category II zone, while estern and southern areas belong to Category IV zone. For assessment standard, see 4.2-1. Table 4.2-1 Standard of environmental noise of urban area Unit dB(A) Cate o Daytime Nighttime 2 60 50 4 i 70 55 4.2.5 Monitoring results and assessment of noise Noise monitoring was conducted during the EA following the above described program. The results of the noise monitoring are presented in Table 4.2-2 which shows the baseline noise conditions of the proposed project site. Table 4.2-2 Monitoring Results of Noise Unit: dB(A) Monitoring points Daytime | Nighttime Average value Standard value Average value Standard value Gaozhai Village 50 60 48 50 Geyu Village 51 60 48 50 Western Bus depot 54 70 49 55 Northern Bus depot 56 70 50 55 Middle Bus depot 50 60 47 1 50 From the above monitored noise, it can be seen that the sound environment quality of this Project is generally now very good good. Northern border of station is close to Pushang Road, however, because there is little traffic flow on the road and the area where this Project is located is basically undeveloped, therefore, the sound environment of this area is comparatively good and quiet. 4.3 Baseline of Water Environment Quality The waste water of this Project will be discharged into the municipal sewage pipelines after being pretreated up to the requirements of entering into the pipelines and will be treated in Jinshan Waste Water Treatment Plant and finally be discharged, into Beigang. Therefore, this assessment will not be surveryed on the spot. GRIEP and FREMS 43 March 2043 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project The effluent from Waste Water Treatment Plant flows into Beigang, so the national controlledmonitoring sections of Beigang, that is, the monitoring materials of Kuiqi Section and Aofeng Section can be utilized. The following items for water quality assessment can be chosen: PH value, BOD5, CODMn, DO, SS, Gasolineeum, NH3-N and lead. 4.3.1 Assessment methods Parameter assessment of single water quality recommended in Technical Guidelines for Environmental Impact Assessment (HJ/T2.3-93) can be used to do the assessment. Standard index method is recommended for parameter assessment of single water quality in HJ/T2.3-93. The standard index of single water quality parameter i at point j is as following: Si, j=Ci, JcCs Where: Cij: concentration of pollutants at the point of (i,j) mg/L; Csj: the standard of surface water quality parameter i, mg/L; The standard index of pH is as following: 7.0 - pHj S PH,j 7.0 -PHsd ,pHj 7.0 Spy, pH, -7.0 H >7.0 SPH'j pH,, - 70 ospH i The standard index of DO is as following: SD, DOf -DO lDj DO DOf -DO, DO SDOJ = 10-9 D ,DOj < DO, DOf =468 /(31.6 + T) ........................... 4.3.2 Assessment of baseline water environment Since the waste water from Jinshan Central Bus Depot is discharged into the municipal waste water pipeline network under Pushang Road and finally into Beigang along the road, the water environment status of Beigang Channel shall be monitored and assessed. The regular monitoring data of Kuiqi Section and Aofeng Section in 2002 can be used for analysis of water environment status. For monitoring results and analysis, see Table 4.3-1.

GRIEP and FREMS 45 March 204 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project 5 Impact Assessment in Construction Period 5.1 Noise Impact Analysis during Construction Period Noise source intensity of construction equipments Noise during the construction period comes primarily from construction machineries and equipment. The noise levels of these machnines and equipment, while operating at construction sites are presented in Table 5.1-1 based on the actual measurements of similar machines in the construction sites from previous projects. Table 5.1-1 Noise source intensity of construction equipments S/N Type of machine Distance between monitoring Lmax points and construction dB(A) equipments (m) 1 Wheel loader 5 90 2 Grader 5 90 3 Vibrating road roller 5 86 4 Road roller with two wheels and 5 81 double vibra 5 Three-wheel road roller 5 81 6 Pneumatic tyre roller 5 76 7 Earth mover 5 86 8 Wheeled hydraulic excavator 5 84 9 Spreader 5 87 10 Generator 5 98 11 Truck 5 92 12 Concrete mixer 5 91 13 Concrete pump 5 85 14 Mobile crane 5 96 15 Hammer and rock drill 5 98 16 Vibrator 5 84 17 Pneumatic wrench 5 95 Forecasting model The noise produced by construction machines can be approximately treated as point source which weakens along with the distance of point source and the mode is as following: Lp = Lp0 -2g0 log.f) What: Lp-Forecasting value of construction noise at r m away from sound source dB (A); Lpo Referenced sound level value at ro m away from sound source dB (A). Through calculation, the noise value of different types of construction machines and the forecasting value of noise at different distance can be obtained, see Table 5.1-2. Table 5.1-2 The Forecasting Value of Noise Produced by all Construction Machines GRIEP and FREMS 46 March 204O Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project at Different distance Name of equipment Lmax Forecasting value of noise at different distance (5m from monitoring dB(A) point) 5m lOm 20m 40m 50m Wheel loader 90 90 84 78 72 70 Grader 90 90 84 78 72 70 Vibrating road roller 86 86 80 74 68 66 Road roller with two 81 81 75 69 63 61 wheels and double vibra Three-wheel road 81 81 75 69 63 61 roller Pneumatic tyre roller 76 76 70 64 58 56 Earth mover 86 86 80 74 68 66 Wheeled hydraulic 84 84 78 72 66 64 excavator Spreader 87 87 81 75 69 67 Generator 98 98 92 86 80 78 Truck 92 92 86 80 74 72 Concrete mixer 91 91 85 79 73 71 Concrete pump 85 85 76 70 64 62 Mobile crane 96 96 90 84 76 74 Hammer and rock 98 98 92 86 80 78 drill Vibrator 84 84 78 72 66 64 Pneumatic wrench 95 95 89 83 77 75 Assessment of Noise Impact during Construction Period Table 5.1-3 Noise Limited Value of Construction Site LAeg [dB(A)] Construction Main noise source Limited value of noise period Daytime Nighttime Earth and Earth mover, excavator and 75 55 stone loader etc. Pile driving All kinds of pile-drivers 85 No construction Structure Concrete mixer, vibrator and 70 55 electric saw etc. Decoration Crane and elevator etc. 65 55 As per the above forecasted results and the survey of sensitive points around the Project, if the distance between sensitive point and construction site is 4-13m, the impact of noise produced by construction at daytime and nighttime on sensitive points will exceed the limited values regulated in Noise Standard on Construction Site. So the noise produced by construction will have an impact on nearby residents. Therefore, strict measures must be taken to reduce the impact of noise on surrounding residents when construction is carried on nearby sensitive points of sound environment. Impacts of Night Time Construction This project involves construction activities near two villages and dozens of households in the rural area. To shorten the construction time and also for GRIEP and FREMS 47 March 204 Environmental Impact Assessment for Fuzhou Jirshan Central Bus Deport Project technical reasons (continued concrete pourting), construction at night, at least in some sections, may be inevitable. Therefore, sensitive receptors i.e., rural households located near the interchange will be most likely subject to great noise impact during night construction. The above table shows that night time construction noise can be up to 20 dB(A) above the applicable standards. At these noise levels, impacted residents may not be able to have a proper sleep, espeically vulnerable groups such as the ill persons, the elderly, babies, students (particularly during the exam time), etc. Such impacts would be particularly significant during the seasons when residents have their windows open at night. In Fuzhou, this means Spring and Autumn. The noise impacts would be less significant in the summer and winter when most residential houses are air conditioned and have their windows closed. Regular glass windows are able to reduce noise levels by about 10 to 15 dB(A) when properly closed. Schools are not sensitive to night time construction as there are no classes at night. 5.2 Impact to Air Quality during Construction Period 5.2.1 Analysis of atmosphere pollution source during construction period As per analog survey, the sources of air pollution during construction period are mainly as following: 1) Dust produced in the progress of excavation, removal and loading and unloading of sandstone and secondary dust produced by transportation during construction period. 2) A certain quantity of waste gas emissioned by machines and transport vehicles which burn oil nearby construction site. 3) Materials with toxic odor and volatility used in construction such as asphalt etc.what has most impact on surrounding enviromnent is dust produced in construction. 5.2.2 Impact to ambient air environment during construction period Dust produced by vehicles transporting materials will have great and long-termn impact on environmental air, which will become worse if the roads in construction site are destroyed or expose. Generally the quantity of dust has proportional relation with speed and weight of motor vehicles and dust quantity on road surface. As per relevant research, when motor vehicles transport earth, the concentration of dust on both sides of roads for a short time can be up to 8-1Omg/m3, exceeding the standard of Class III Air Quality. But the concentration of dust will rapidly reduce with the increasing of distance. The concentration of dust at 200m under lower wind direction almost approaches that of dust in the upper wind direction at corresponding point. As per analysis and comparision of similar projects, secondary dust produced by transportation will cause pollution to the residents, especially the residents living in the houses at the first row, near construction site. Dust can also be produced by demolition and removal of buildings, GRIEP and FREMS 48 March 204 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project construction of roads, mixture of building materials and excavation and drilling of dry ground etc. During construction period, it shall not be ignored that dust also produces when there is strong wind or earth is backfilled, because the plants are destroyed and the ground surface exposed and water vapored, dry and loose particles are formed on ground surface so that the ground surface is loose. Construction machines and transportation vehicles which bum oil will emission waste gas of certain quantity near the construction site. Construction sites are generally located at the sections with busy traffic, however, the waste gas from construction equipments and vehicles only accounts for little of total amount, so it will not have great impact on surrounding environment air if only the maintenance of equipments is strengthened and emission of black smoke is reduced. Dust produced by construction suspends in the air, if it is inhaled by constructors and surrounding residents, all kinds of diseases on respiratory tract will be caused. Moreover, a large quantity of disease-leading bacteria in dust will infect other diseases and seriously affect health of constructors and surrounding residents. 5.3 Impact to Ecological System During Construction Period Construction of the project will occupy land and destroy all the vegetation on the land. Replacing the vetegation will mosty be concrete structures and pavement. The impact is permnant although the lost vetegation will be compensated with landscaping program on the site and nearby areas. At the proposed site, there is no sensitive ecosystems and far away from the wetlands and forest land at the Nantai Island. The construction of the bus depot will not have direct impacts to those sensitive ecosystems. 5.4 Impact to Water Environment during Construction Period The waste water produced in construction is mainly from: muddy surface runoff produced by excavation, flush and washing water produced by construction machines and transportation vehicles, sanitary waste produced at the construction camp, surface runoff produced by overburden scoured by rain, building mud, rubbish and waste etc. . A large quantity of sediment and dust is produced by removal of buildings and excavation of ground during construction period and most of surface runoff produced by rain gathers into surrounding water area through rivers. There are no perfect drainage facilities during construction period, so the discharge of waste water will affect the receiving waterbody of ground surface at construction section and add sediment to water. Although there is little water, the impact time is long, to which shall be paid attention by construction unit. Fuzhou lies in the subtropical zone where the annually average rainfall can reach 1,354mm and July, August and September are flood seasons, with many GRIEP and FREMS 49 March 2049 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project storms in summer. It is easy for rain to flush the construction site and pollute surrounding environment, especially the rainwater on ground produced by flushing construction site will block city rainwater drainage network system. During construction period, a large amount of constructors and machines enter into construction site, if it rains, the pollutants on surface source in construction site will be discharged into nearby water area and will affect water quality. In addition, the impact on surrounding water environment also includes the impact on water environment caused by direct discharge of sanitary waste produced by constructors and water used to wash vehicles into nearby water area. In a word, there are mainly the following points: (1) If the sanitary waste produced by constructors isn't treated collectively, it shall not be discharged into water area. The sanitary waste includes washing water of constructors, waste water from dining room and washing water of toilet and rubbish not treated collectively. All the sanitary waste is directly discharged into nearby rivers. The concentration of sanitary waste produced by 250 construction is generally low, with daily discharge volume of 12.5m3. In main pollutants emissioned, there is 1.88kg/d BOD5, 3.1 3kg/d CODcr and 1 .25kg/d SS which shall be properly treated. (2) The rubbish produced in construction includes sanitary waste of constructors, waste of construction materials, waste after repair and other similar waste, thereinto, the sanitary waste of constructors includes all kinds of food, rubbish from kitchen, offal, plastic dishware, cup or bag and other paper, cloth or glass waste commodities. If the rubbish quantity produced by one person on one day is lkg, then the total quantity of rubbish each day is 0.25 tons. The rubbish from building materials mainly includes scraps of wood, iron, paper and lime in construction. Rubbish after repair mainly includes waste parts, ropes and scrap iron. 5.5 Impact of Construction Camps A construction camp will be set up on or near the Jinshan Bus Depot site with an estimated 250 workers and management/supporting staff at the peak of the construction. Mos of the workers will live at the camp during the period of construction. At the same time, the construction camp will also be the site for materials storage and plinmg, construction machinery parking and maintenance, and other activities necessary for construction preparation and administration. The operation of the construction camp will create potentially adverse impacts to the natural and social environments. Besides the wastewater and solid waste generated at the camp which could potentially affect the quality of the environment in the area waterbody, the camp would have other impacts, including: * Camp satination and hygiene, which, when not managed propertly, could affect the health of workers as well as contaminating the site. * Potential epidemic caused by poor hygiene and sanitation and area epidemic spreads sach as diarrhea, hepitatis, flu, AIDS and others. These epidemic dieaseas if occurred would not only affect the workers GRIEP and FREMS 50 March 2069 Environrental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project but also possibly villagers in nearby villages. * The oil and fuels stored onsite, if not handled properly, would cause soil contamination at the site from spills, dripping, and other accidents. Machinery and vehicle maintenance could also be a source of contamination from leaking oils, wash effluent, etc. - The fuel storage on site could be a source of fire. Mitigation of these impacts are described in later section and the EMP. 6 Impact Assessment during Operation Period 6.1 Analysis of Impact on Air Environment 6.1.1 Analysis of the source of pollution Learned from analysis of the preceding works, the main source of atmospheric pollution is the emission discharged from automobile and oily smoke from the canteen. The oily smoke etc. exhaust gas generated by the canteen shall be let out from the chimney at the top of the building guided via the inner set smoking pipe after the secondary treatment, less impact to the surrounding environment. The emission from the automobile belongs to the non-point source. The atmospheric pollutant of the emission from the automobile contains principally NOx, CO. When this parking area is in the peak flow of traffic, refer the maximum intensity of non-point source to table 6. 1-1. Table 6.1-1 The maximum discharged source intensity from the source of atmospheric pollution Unit: mg/s Type of source HC NOx CO intensityI Non-point source 300 190 1850 As regards to the source intensity of the total non-methane hydrocarbon, the calculation shall be made by adopting the regression equation of total hydrocarbon consistency (CTHc) and non-methane hydrocarbon one (CNMHC) discharged from automobile in The Relation Between Total Hydrocarbon and Non Methane of Automobile Discharge in Urban Road (Deng Shun xi), the equation is: CTHC=1. 3963+1. 0322CNMHC The maximum source of the total non-methane hydrocarbon obtained from above formula is 298.65mg/s. 6.1.2 Mode of atmospheric diffusion For the elevated point source, the Gaussian formula shall be employed to calculate the ground consistency of pollutant. When the height of the chimney is in average wind speed in> 1 .5m/s(hereinafter called availability of wind), GRIEP and FREMS 51 March 2061 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project the hourly average consistency on ground shall be calculated as per the following formula: C = Q exp - Y . F F=2exp 2 c When the height of the chimney is in average wind speed in< 1. 5m/s (hereinafter called breeze, calm wind), the one-time average consistency on ground shall be calculated as per Gauss integration formula for stacks, which is: 2Q (x-U T) 1( y2 ___ C f (2,2 exp 2o2 exp - 2 2expt- dt 02 *O~ IIg g In the above formulas: C - - Ground hourly average. consistency(mg/Nm 3) Q Source intensity(mg/s) U - The average wind speed at the height of the chimney(m/s) a,, > a, az- The perpendicular diffusion parameter(m *m) for longitudinal, transverse wind,; H e- Effective source height(m) y Distance of transverse wind(m) The equivalent point source method shall be adopted for non-point source, this non-point source shall be made equivalent to the imaginary point source of windward, i.e. One initial diffusion dimension (ao, and azo ) is added in the formula of point source, then the distribution of consistency for the pollutant shall be calculated with Gaussian Mode. However, the parameter value of atmospheric diffusion for the point calculation shall be defined in accordance with the position of the imaginary point. a1 =cT1(X+Xy),) , =a,(X+X,).

(2) Wind direction The seasonal wind climate in this region is notable, the annual dominant wind direction is south-southeast one, due to the influence of southerly wind in summer, and the frequency of this wind direction appears more remarkable. The frequency of wind is relatively dispersed, despite that the highest frequency of wind direction is southerly wind, the frequency of north wind and northerly wind is not low. This region is closer to the sea, the daily change of wind direction possesses the apparent characteristics of land and sea freeze, generally the cycle is based on day and night, the morning is northwest wind, change after lunch to southeast wind, it is more obvious in summer. 6.1.5 Predicted results and assessment Because the source of the atmospheric pollution for this project is only discharged in discontinuity, the estimation is only made for the hourly average consistency distribution of leeward axial ground, and the impact extent and scope to surrounding atmospheric quality when the maximum discharge of emission from automobile in the park area. Known from the table 6.1-4 and 6.1-5, the impact to the scope of lOOm around in case the maximum discharge of emission is made from automobile. Got in accordance with table 6.1-4, the impact scope to lOOm around of NO2 in GRIEP and FREMS 53 March 20O Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project emission of automobile is 0.005 - 0.0713mg/m3, is 0.2% - 29.7% of assessment standard; obtained from table 6.1-5, the impact scope to 1OOm around of CO in emission of automobile is 0.0082 - 1.1020mg/m3, is 0.082%- 11.02% of assessment standard. Learned from Table 6.1-6, in case of the peak house for this project, in the impact of NMHC discharged, the maximum impact value to surrounding 1 Om is 0.1779mg/m3. Consequently, the impact to surrounding 1OOm and beyond is quite small by NO2 and CO in the emission of automobile produced in the construction of this project.

The Jinshan is a community park and used by the urban and rural residents in the region. In particular the park is frequented by residents during the momings and evenings for exercises and other acdtivities. Increased air emission from bus depot operations could affect the park visitors, particularly to the elderly who are more sensitive to the effect of poor air quality to their respitary systems. This impact would be somewhat limited as the air emissions are primarily in very early hour (5:00-6:00) in the moming and late hour (10:00-11:00) in the evening, when buses leave and return the bus depot in large volumes. In other hours of the day, there will be very limited bus traffic at the depot and thus limited air emissions. In both these two hours of the day, the park visitors would be limited and therefore, the impact of the air emissions from buses to the park goers will be limited. As a mitigation, the bus depot will notice the public, particularly the park visitors of the worsen air quality from bus depot operation during those two hours, providing waming to those with poor health or otherwise sensitive to the increased contamination in the ambient air. The park visitors may choose to avoid these two hours (easily) and visit to the park in other time of the day. The potential impact to flower culture in the nearby flower garden would be long lasting. In general flower growth could be affected by serious air pollutation although many species could gradually adopt the changing environment. The exact impact to the flowers depend on many factors, such as species, level of contamination, weather, soil conditions, seasons, etc. The exact impacts of bus emissions to the flower culture are difficuilt to fully understand without a long term observations and study. For Jinshan bus depot, however, the flower gardens, together with the villagers will be relocated to make way for an industrial park development (not related to this project). 6.2 Environmental Impact Assessment of Water The separate system for rainwater and wastewater shall be adopted for the drainage system of Jinshan Maintenance Yard. The waste water generated by main production workshops such as vehicle washing workshop, maintenance workshop and the canteen will enter into the respective oil separation tank, and will be discharged into the public pipe network of waste water outside the parking area after being treated through the gas floating system, the sewage quantity is approximately 357.7m3/d, and finally enter into Beigang after reaching the standard through the treatment of Jinshan Waste Water Treatment Plant. The rainwater in initial stage is 88.4m 3/d, having satisfied the requirement of the third class standard by separating oil and desilting, this part of rainwater can be directly drained into the Waste Water Treatment Plant for treatment public via pipe network. So, if the maximum sewage quantity is taken into account, the maximum GRIEP and FREMS 55 March 2065 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project discharge quantity of wastewater shall be 446.1 m3/d. the waste water shall be discharged into Jinshan Waste Water Treatment Plant after reaching the third class standard in the "Comprehensive Effluent Standard of Waste Water" through the pre-treatment, and finally into Beigang after reaching the first class standard in the "Comprehensive Effluent Standard of Waste Water" through the treatment of Jinshan Waste Water Treatment Plant. This project generates less waste water, and discharged into Beigang after reaching the standard through the treatment of Jinshan Waste Water Treatment Plant, consequently, the waste water of this project will have less impact to water environment. 6.3 Noise Impact Assessment during Operation Period 6.3.1 Applicable Standards According to Fuzhou Urban Environmental Plan, the proposed bus depot site has been designated as Class II and Class IV noise zones and applicable noise would therefore be Class II and IV at the GB3096-93. To be more specific, the north and west of the depot is roads and therefore Class IV noise standards will be applied (70 dB(A) for day time and 55 B(A) at night) whereas east and south is residential area and Class II will be appliced (60 dB(A) for day time and 50 dB(A) for night). 6.3.2 Noise Impact Prediction Noise Sources According to Fuzhou Jinshan Central Bus Depot Porject Feasbility Study Report, the bus depot will have functions of maintenance, dispatching and parking operations. Based on the information provided in the feasibility study report and by the project owner, and in comparison to with similar projects elsewhere, the main noise sources of the proposed bus depot will include compressor, maintenance machines, and buses. The noise impacting time is primarily day time when the maintenance activities take place and 5:00 to 6:00 and again 10:00 to 11:00 when buses leave and return to the bus depot. The noise intensity is presented in Table 6.3-1. The traffic volumes at the two roads near the bus depot, according to the feasility study report.

Considering the above considerations, the noise at sentiive receptors can be predicted by the following method. 1 ) Indoor noise source intensity model The indoor noise at the window L p can be predicted by: L =L i + 10 log 4Q,, + 4 Where, LWi - the ith noise source; Q - noise orientation indix r, distance of the ith noise source to the window R - a constant on number of rooms Therefore, the noise levelL at the window of a room where there are k noise sources is: LP ~ 10 log I 10 The noise level outdoor Lp2 close to the window is: Lp2 = Lp, - (TL + 6) Where TL - noise attenuation of the building 2) Outdoor noise prediction model The noise outside the window is considered as noise source which may be deemed as area source of length by width by height (axb,a X b) then, the noise at the property boundary Lr would be: a Whenr'- L, =LP2 -A )r When -- , Lr = L - 10 log -- 20 log - A 7r a a 3) The traffic noise prediction Cadna/A model is used to predict noise from traffic at parking and dispatching areas. According to the noise source intensity, noise impacting time, location of the noise sources, structures and barriers to the noise sources and the environmental conditions of the site, noise level is predicted. All noise sources will be considered in the model the predicted results are those from combined noise sources The traffic volumes used in the predicting model is 160 buses per hour occurring twice per day (22:00-23:00) and (5:00-6:00) at the parking area while the average traffic volume at the dispatch area is 100 per hour throughout the day during the operation hours. The noise prediction results and impact assessment Based don the above described models and methodology, the noise levels of the bus depot are predicted for the day time and night time (22:00-23:00), respectively and the results are presented in Table 6.3-1 and noise isolines are shown in Fig.6.3-1 (day time), Fig.6.3-2 (night) and Fig.6.3-3 (peak hour)..

The exceedance is expected to be about 2-16 dB (A) during the day time and 5-16 dB at night. Clearly the incremental increase in noise at the site will result in significant impacts to the surrounding area. In particular, the bus movement at the parking and dispatching operations will be the strongest noise sources, reducing the acoustic environmental quality at the site. However, it should be noted at the impact occurs only during the day time and very limited hours at the night (up to 23:00). There will be no noise impact after this hour until early morning at 5:00. However, according to Fuzhou Urban Master Plan, the land zoning surrounding the site is a major substation to the east, the north is Pushan road and beyond the road is a residential area, south is Hongjiang road and beyond GRIEP and FREMS 58 March 2N6O Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project the road an industrial park (currently Geyu and Gaozia villages) and west is the proposed Jinshan Park land. Clearly at the immediately adjacent areas, there are no sensitive receptors and the two villages will be relocated (under a different project) to give a way to an industrial park development. Therefore, the increased noise at the site and surrounding areas are not expected to have direct impacts to any sensitive facilities or communities. The future development of the land surrounding the bus depot shall be controlled to avoid building any facilities and structure sensitive to noise from bus depot operations. GRIEP and FREMS 59 March 2069 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project 7 Impact Analysis of Electromagnetic Environment The impact analysis of electromagnetic environment was performed in accordance with the experts' requirements. This chapter was prepared by Fujian Provincial Radiation Supervision Station. Since the 220kV Jianxin Substation is close to the project site and a line corridor consisting of one 220kv overhead transmission line and one 110kV overhead transmission line cross the site, this assessment subject is added in accordance with the experts' review comments on the Outline of Environmental Impact Assessment on the World Bank Financed Parking Area Construction of Fuzhou Jinshan Central Bus Station. The 220kV and 110kV transmission lines, which share one tower, are of two-loop overhead lines. The route of the 11 OkV transmission line is to be changed. 7.1 Contents and Methods of Special Assessment and Impacted Sensitive Receptors 7.1.1 Contents of special assessment (1) The impact of power-frequency electromagnetic field, produced by the 220kV Jianxin Substation and its 220kV & 110kV overhead transmission lines, on the staff and the public in the parking area of the bus station, the interference of the power-frequency magnetic field to the CRT display in the dispatching center; (2) The interference of the 220kV Jianxin Substation and its 220kV & 110kV overhead transmissionk lines to the communication equipment in the dispatching center of the parking area. Item (1) above mentioned is mainly assessed in accordance with the measured value of power-frequency electromagnetic field. Item (2) is analyzed based upon the typical parameters of the communication equipment and common radio interference of the 220kV substation and 220kV overhead line. In accordance with the preliminary design drawings of the Project, the spaces with small persons, short standing time of train and large distance to the 220kV overhead line are not considered, such as the parking area and maintenance shop for vehicles. The dispatching center, waiting hall and dormitory building are selected as the impacted sensitive targets. In addition, the chapter gives a brief analysis to the risks of gas station and dispatching center of the Project when the 220kV overhead line and 220kV Jianxin Substation are struck by stroke of lightning. 7.1.2 Assessment standard (1) Assessment standard for the impact of power-frequency electromagnetic field, produced by the high-voltage power transmission & transformation project, on the public is Technical Regulations on Environmental Impact GRIEP and FREMS 60 March 209 Environmental Impact Assessment for Fuzhou Jirshan Central Bus Deport Project Assessment of Electromagnetic Radiation Produced by 500kv Ultrahigh Voltage Transmission and Transfer Power Engineering (HJ/T24 -1998); "1.3The code is applicable for the environmental impact assessment of electromagnetic radiation produced by 500kV supervoltage power transmission & transformation engineering. The code may also be used as the reference to environmental impact assessment of electromagnetic radiation produced by llOkV, 220kV and 330kV power transmission & transformation engineering." "2.2.4.2 ... It is recommended that the value 4kV/in shall be the assessment standard for power-frequency electric field in residential area and the power frequency limit 100 IT during all-day radiation to the public issued by the International Radiation Protection Association be the standard for magnetic induction intensity." (2) For there may be many pedestrians in the bus station and the pedestrians in the parking area may get shocks when walking under the high-voltage line by taking umbrella in rainy day, the limit to the intensity of power-frequency electric field (3kV/m) produced by high-voltage corridor confirmed by Japan for the locations passed by persons with umbrella will be the assessment standard. (3) Interference of power-frequency magnetic field, produced by the high-voltage power transmission & transformation project, to CRT display will be analyzed in accordance with the Information Technology Equipment--Immunity Characteristics--Limits and Methods of Measurement (GB/T17618-1998). The limit to noise immunity is lA/m- l.26gT. 7.2 Monitored Results of Power-Frequency Electromagnetic Field in the Project Site 7.2.1 Monitoring instrument Please see Table 7.2-1 for the monitoring instrument.

Two high-voltage overhead lines (110kV and 220kV) cross the site from the east to the west. The 110kV overhead line is planned to be moved to the green belt at the north side of the site. At that time, its distances to the impacted sensitive targets will be larger than those of the 220kV line and its voltage class is lower than that of the 220kV overhead line, so the 110kV overhead line is not taken into account during monitoring and assessment of the current status. Layout of monitoring points is as follows: (1) One side of the dispatching center, waiting hall and dormitory building close to the 220kV overhead line; (2) Intensity distribution of power-frequency electromagnetic field on cross section of 220kV overhead line in relatively open area; (3) Along the enclosed wall at the west side of the 220kV substation at a distance of lm to the wall; (4) Along the direction vertical to the enclosed wall of the substation. Please see Fig. 7.2-1 for the detailed locations. Intensity measurement for power-frequency electric field is useless because the obstacles in the site (buildings, trees, etc.) are still not demolished, so only the intensity of power-frequency magnetic field was measured at most points and the intensity of power-frequency electric field was only measured in relatively open area.

It is concluded by comparison of the monitoring results of the measuring line 1Om out of the enclosed wall of the substation (measuring points 22-30) and the measuring line 1m out of the enclosed wall (measuring points 31-40) (see Fig. 7.2-2) that intensity of the power-frequency magnetic field out of the enclosed wall of the substation attenuates fast in the vertical direction, which change is mainly impacted by the line.

Standing time of the personnel above mentioned in outdoor area is relatively short and the measured max. intensity of the power-frequency electric field in the project site (0.253kV/m) is far lower than the assessment standard for the power-frequency electric field in residential area (4kV/m), so the power-frequency electric field produced by the high-voltage overhead line and substation will basically have no impact on the personnel above mentioned. The measured max. intensity of power-frequency electric field in the project site is 0.253kV/m, which is far lower than the assessment standard for power-frequency electric field (3kV/m) that may "cause persons to get shocks when walking under high-voltage overhead line with umbrella in rainy day". Therefore, the pedestrian will not get shock when walking under the 220kV overhead line by taking umbrella in rainy day within the scope of the project site, including the staff (drivers) and the passengers. 7.3.2 The power-frequency magnetic field's impact on personnel It is hard to shield the power-frequency magnetic field and its indoor intensity is nearly the same as the outdoor intensity, so some persons will be exposed in the power-frequency magnetic field. As shown in Fig. 7.2-2, intensity of the power-frequency magnetic field GRIEP and FREMS 66 March 200 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project produced by the substation attenuates quickly along with increase of the distance to the enclosed wall. The power-frequency magnetic field in the project site is-mainly produced by the 220kV overhead line. Max. power-frequency magnetic induction intensity is 0.672jiT under the 220kV overhead line and 0.327gT at the impacted sensitive targets. Both values are far lower than the assessment standard for the subject (I OOgT) and the strict international standard (I T)), so it will not impact health of the personnel in the impacted sensitive targets, including the dispatching center, waiting hall and dormitory building. 7.3.3 The power-frequency magnetic field's impact on CRT display Relatively obvious character blithering of the CRT display will happen when the power-frequency magnetic induction intensity is larger than the limit to noise immunity (1.261gT) of the CRT display. Then, use of computer will be impacted. It is recorded in Table 7.2-2 that the measured max. power-frequency magnetic induction intensity at the impacted sensitive targets (0.327jiT) is far lower than the limit to noise immunity (1.26JT) of the CRT display, *so obvious character blithering of the CRT display will not happen in the dispatching center and dormitory building. 7.4 Analysis of impact on radio interference 7.4.1 Categories of communications equipment Electrommunications equipment of the Dispatching center includes wire communications, interphone, GPS positioning system, which are mainly wire communications. Wire communications is based on telephone line, which will not be interfered. Interphone, GPS positioning system will be interfered based on signal-noise ratio and modulation mode of signal, etc. Intensity of receiving signal and intensity of interference field will be estimated on the two kinds of communications system, as well as the signal-noise ration will be calculated, which is the basis of assessment of the range of interference as the following. 7.4.2 Intensity of receiving signal of interfered communications equipment 7.4.2.1 GPS positioning system Precision of positioning of GPS system of the project, which could be 15m, will meet the requirements. It doesn't need difference positioning (DGPS) and its received signal of radio position finding is civil GPS signal, which is sent out by GPS satellite with the frequency of 1575MHz. Power launched by GPS satellite is 20-50W, with direct-to-ground height is about 20,000km. In case being estimated conservatively, launching power is GRIEP and FREMS 67 March 20O Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project as P=20W as well as the distance between GPS satellite and receiving point is as r =27,000km, antenna gain is as G=3dB (two times), and signal field intensity of its ground receiving point is E=(3OPG)112/r= 1.3 x l 06V/m= 1.3jiV/m Namely E= 2.2dBgiV/m. Communications technology of spread spectrum is adopted in GPS system, which transmission gain of spread spectrum reaches above 50dB and can work normally under situation of electrical level of GPS signal is less than that of wireless noise greatly. The effect of this receiving electrical level is equal to receiving effect of electrical level of non-spread spectrum signal, which is 52.2dBpV/m. 7.4.2.2 Interphone Communications radius of professional interphone system of the project is 5-8km, which can be used in the city where there are so many high buildings and available frequency band above 400MHz. The actual min-receiving field intensity is calculated as 51 dBpV/m (the data from http://www.freetalker.net/zl/show/ 200312002.htm). 7.4.3 Power frequency of interfered communications equipment and intensity of interference field at the location of the transformer substation and trolly wire. 7.4.3.1 Transformer substation Monitoring result of Minqing 220kV transformer substation is quoted in this assessment. Intensity of interference field at the location of 20m beyond the enclosures of the transformer substation that is provided with the frequency of 30MHz, will not more than 10 dBflV/m, considering factors of the weather, in case being estimated conservatively, field intensity is increased 1OdB, the max intensity of interference field of 30MHz is 20 dBjiV/m. Each frequency of interference field of the transformer substation is decreased several-fold as 6dB. For the.frequencies of 30MHz, 400MHz and 1575MHz are decreased 3.7 times and 5.7 times respectively. According to damping rule of frequency and the max-intensity of interference field of 30MHz, under the frequency of 400MHz and 1575MHz, intensity of interference field at the location of 20m beyond the enclosures of the 220kV transformer substation are -2.4dBpV/m and -14.2dBgV/m respectively. The distance between the dispatching center and the transformer substation is 400m, which is 20 times of the distance from the location of 20m beyond the enclosures of the substation. In case the distance of the 220kV distribution unit center will be taken into consideration, the intensity of interference field is decreased 20dB calculated based on damping rule (inverse-square law) of crossing distance of aerial wires. The intensity of the transformer substation at the dispatching center under the frequencies of 400MHz and 1575MHz are -22.4 dBgV/m and -34.2dBg.V/m respectively. 7.4.3.2 High-voltage trolly wire GRIEP and FREMS 68 March 20O Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project Wireless noise produced by high-voltage trolly wires is mainly corona discharge noise. Frequency spectrum of corona is concentrated less than 30MHz, which could not influence interphone (f>400MHz) and GPS positioning system of the project. In infrequent special cases, in case insulator of iron tower of high-voltage trolly wire has defect, which shall cause spark at the hole or fracture and air gap would discharge, the frequency spectrum will be extended more than 100MHz. Being shown as the above-mentioned Diagram 5-46 of the teaching materials (basis of reference (OdB) of the diagram is corona noise less than 0.5MHz), on the interfered frequency that is cared about, the comparative intensity of interference field of the frequency >400MHz is -24dB, as well as that of 1575 MHz (a little bit beyond the range of the frequency in the diagram) would be less than -50dB. Because the minimal horizontal distance between the main building of the dispatching center and the insulator of the 220kV iron tower is 40m, the field intensity is decreased 6dB than that at the location of 20m according to the damping inverse-square law. In case wireless noise of the 220kV high-voltage trolly wires reaches the standard (the intensity of interference field at the location, where is 20m distance between ground cast shadow of the side conducting wire at the frequency of 0.5MHz, is 53dBgV/m), and'the estimated value of the intensity of the interference field at the location where the airspace of the insulator of the iron tower at the frequency of 400MHz is 53dBgV/m-24dB-6dB=23dBgiV/m, and that at the frequency of 1575MH is 53dBgV/m-50dB-6dB=-3dBRiV/m. 7.4.4 Signal-noise ratio and assessment on interfered communications equipment Noise power of receiving frequency range is directly proportional to the receiving bandwidth. Occupying bandwidth of civil GPS positioning system is 5MHz, which is 556 times of bandwidth of resolution ratio of quasi-peak detector of 9kHz at the frequency band between 0. 15'-3OMHz. The intensity of interference field in its receiving bandwidth shall be added 27.4dB. The maximal frequency departure of interphone is ±5kHz and that of the effective bandwidth of signal is 10kHz, which intensity of interference field shall be added 0.5dB. When the dispatching center only just takes the wireless interference of the 220kV transformer substation into consideration, signal-noise ratio of 400MHz interphone is 51 dB V/m-(-22.4dB gV/m+0. 5dB)=72.9dB; signal-ratio of 1575MHz GPS system (considering extending frequency gain) is 52.2dBgiV/m-(-34.2dBgV/m+27.4dB) =59dB, which is excellent. Therefore, construction of the 220kV transformer substation will not influence GPS positioning system and interphone of the dispatching center. When the dispatching center just takes the wireless interference of the insulator's airspace of the iron tower of the 220kV trolly wires into consideration, signal-ratio of the 400MHz interphone is 5ldBpV/m-(23dBpgV/m+0.5dB) =27.5dB, which is bigger than the standard signal-ratio of 12dB; signal-ratio of the 1575MHz GPS system is 52.2dB,jV/m-(-3dBgV/m+27.4dB)=27.8dB, where communications is normal. Therefore, it is defective to lead out the 220kV trolly wires at the insulator of GRIEP and FREMS 69 March 200O Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project the iron tower when the new transformer substation is constructed, but when the airspace is discharging, it will not influence GPS positioning equipment and interphone. 7.5 Risk Impact Assessment on the Transformer Substation and High-Voltage Trolly Wire Gas station is the top category of lightning-protection building of Criterion for Lightning-protectionDesign of Building (GB 50057-1994), which shall be taken measures for lightning-protection. Because there are high-voltage trolly wires, which are easy to be lightning-stroked, nearby the gas station and the dispatching center, it is easier to produce electric spark by lightning strokeg in gas station and destroy the electric equipment in the dispatching center. Surge protector, equipotential connecting and masking grounding shall be installed in the dispatching center. The distance between intended removal of high-voltage trolly wire and gas station is only 25m, so the electric spark produced on trolly wires by lightning shock may threaten the safety of the gas station. The induction voltage of lightning in gas station will be high, so whether the plan of trolly wires is practical shall be accepted by the Lightning Protection Department, unless underground cable shall be adopted. The lightning-protection drawing and facilities shall be examined and accepted by the Lightning Protection Department. On the other hand, fire or explosion under the trolly wires will threaten the trolly wires. In case accident happens, it will bring about power cut in a large area. Therefore, trolly wires shall be kept a suitable distance with the gas station to ensure that they would not influence each other. In accordance with Regulation on the Protection of Electric Facilities of No.39 Decree of the State Council of the PRC, the protected area of 220kV and 110kV overhead electric line are the- region in which sideline of conducting wires are extending horizontally 15m and 10m, and vertical with the two parallel surfaces. According to the plane layout of the initial design, gas station, dispatching center and employees' dormitory and the Waiting Hall accord with the requirements of Regulation on the Protection of Electric Facilities. 7.6 Summary and Mitigation Measures 7.6.1 Summary The construction of the new 220kV transformer substation and its 220kV trolly wires will not interfere with the interphone, GPS positioning equipment and CRT display in the dispatching center. The intensity of power frequency electromagnetic field of the dispatching center, waiting hall, employees' dormitory is less than the assessing standard of impact of power frequency electromagnetic field produced by high-voltage power transformation engineering on the public. The intensity of power frequency electromagnetic field is under the strictest standard in the world; therefore it shall not influence the workers and the public in the bus depots. People who are walking under the 220kV trolly wires will not suffer lightning shocking in the rainy day. GRIEP and FREMS 70 March 20a Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project The gas station, dispatching center, employees' dormitory and waiting hall of the layout of the initial design shall accord with the requirements of Regulation on the Protection of Electric Facilities. In case the intended 11 OkV trolley wire suffers from lightning shocking, it will threaten the safety of the gas station. Whether the plan of trolly wires is practical shall be accepted by the Lightning Protection Department, unless underground cable shall be adopted. The lightning-protection drawing and facilities shall be examined and accepted by the Lightning Protection Department. 7.6.2 Mitigation Measures The gas station and dispatching center shall take measures that can protect lightning on the high-voltage trolly wires. 7.6.3 Suggestion Interphone is suggested to use on the roofing to improve the signal intensity of the interphone. The electronic equipments in the dispatching center shall be allocated on one side of the 220kV trolly wire to decrease the impact of lightning on the high-voltage trolly wires. GRIEP and FREMS 71 March 20?I Envirornental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project 8 Risk analysis and Plan For Emergency. The project includes one gas station. According to the requirements of the experts, the gas station shall undergo risk analysis and havet a preliminary plan for emergency. The service station is flammable and explosive, which is the key department of fire protection. Precaution shall be put into the most important position in the security management of the service station, where shall be kept away and managed strictly, to put the key position on the protection of fire and explosion. At the same time, the preliminary plan for emergent accidents shall be formulated by any possibility. The related managers and the staff of the service station shall be familiar with the preliminary plan for emergent accidents and execute exercise on the site according to the requirements in order that they can do their own work and take remedial measures timely when the accidents are coming to decrease the loss at the minimal level. 8.1 Categories of Accidents and Risk Analysis Categories and risk analysis of gas entrainment There are four categories of accidents in the gas station: the first one is burning, the second one is explosion and leakage, the third one is explosion after burning and the last one is burning after explosion. No matter what kind accident happens, it will bring about very serious consequence. Therefore, prevention shall be strengthened to put an end to the accidents. At ordinary times, all the staff of the station shall study technology seriously and know well the complete process of the gas station and understand the hazard of the accidents to keep no risk at all. Meanwhile, the study and exercise of the preliminary plan for accidents shall be enforced in order to the accidents can be solved at any moment. According to the technology and equipment of the gas station, the possibility, hazard, prevention and emergency treatment are included as the follows: (1) Burning. Burning shall meet the following two conditions: the first one is gas leakage and the second one is burning source. The gas leakage may happen at many places, such as pipes, valves, gas collectors, compressors, desiccators, recovery pot and filtering pot etc. Except that the repair and maintenance shall be enforced, the inspection in the operating process is more important. In case the leakage is checked up, it shall be solved carefully in time. Gas leakage shall be prevented well firstly. The second point is preventing the burning source. Spark may be produced on the electric equipments (including the wire terminal becomes flexible, the electrical machine is not sealed rigorously), and produced by collision of metals, static electricity (static on equipment such as gas-entraining gun, gas pipe, chemical fiber clothing of workers and normal flashlight etc), wrong operation, fault of heating equipment and other fire sources. The MITIGATION MEASURES is enforcing the maintenance and inspection of equipment (including ground lead), cross-under stirrup of pipe grounding etc. In addition, knocking and collision shall be escaped in the GRIEP and FREMS 72 March 20O3 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project repair. When necessary, the gas supply shall be cut off in order to protect well. The works can't wear chemical fiber clothing on duty (2) Explosion or leakage. The explosion in the gas station is mainly happened on the pipes and equipments when the pressure exceeds the intensity that the pipes and equipments could endure. The reasons are composed by two aspects ordinarily. The first one is the system pressure exceeds the regulated pressure; at last it exceeds the utmost limit of intensity of the equipment and its fittings, and then bring about the explosion or local burst. The second one is that during the operating process of the equipments, pipes and fittings, the intensity and enduring ability are decreased because the factors of corrosion and fatigue etc, and then the explosion will be brought about and the leakage will also be brought about because of loosing of conduit joint. The first step of prevention against this kind of accident is preventing overpressure and enforcing the maintenance. Overpressure operation is prohibited, therefore, in the maintenance of the equipment, compulsory-inspecting instruments such as safety valve and manometer shall be submitted for censorship regularly in order to prevent against overpressure brought about the out-of-run of the equipment. In terms of prevention against corrosion and fatigue of equipments, it is required to solve through maintenance. In terms of gas bottle, it shall be prevented against hydrogen brittleness produced by corrosion of hepatic gas; then it shall be submitted for censorship. (3) Explosion after burning; In case the burning of the gas. can't be exterminated rapidly, the containers in the gas station will be heated, and the air pressure will be decreased rapidly; in case the exhausting is not easy and smooth, the explosion will be happened. This case is not easy to happen because the gas bottles were experienced the similar experiments. But in case the fire is so campaigned and the heating is decreased rapidly, the rapid increasing of pressure will bring about the explosion. The other situation is fuilmination. Because the burning is heating the gas in the container, and the gas in the container is leaking through the safety valve; when it mixes with the air on the mixing ratio of 5%-15%, the explosion will be happened in case it meets the fire source. Therefore, the gas bottle storeroom shall not be closed and the draught of the storeroom shall not depend only on fans; the storeroom shall be open wide or half-open wide, at least scuttle shall be set up; and shall be isolated with machine room and station through fire partition to decrease the accidents. (4) Burning after explosion. In case the equipment and pipes explode, the gas will be leaked. In case there are not fire sources outside and no violent collision, the buming will not happen; in case the air supply passes the explosion point, a large amount of the gas will be leaked continuously to form fuel and air mixture; at this time, it is very dangerous that the burning after explosion will happen. 8.1.1 Risk analysis of fueling The risk features of oil storage tank area are reflected as oil spilling, oil leak, bleeding, oil leakage, fire and explosion. The following table lists the main GRIEP and FREMS 73 March 20O3 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project risk feature and the analysis of reasons. Table 8.1-lRisk Analysis of Oil Storage Tank Area Risk category Hazard Oil leakage (spilling, leaking Pollute the Breakage of oil tank, pump, and bleeding) groundwater compression and pipes Pollute the surface Corrosion of buried tanks and pipes water Flooding point and bumping of oil Bring about fire and tanks explosion Capacity of fire-dike is not enough Leakage Wrong operation Fire and explosion Property loss Oil leakage Casualty of the staff Mechanical, high temperature, electric Polluting the and chemical sources of fire environment 8.2 Key points of emergency plan Being dead against the above-mentioned features, in case the gas station suffers no matter what kind of accident, it shall take remedy measures rapidly to control the exacerbation of the accident. For this, the key points of emergency treatment are: (1) Fire accident: the gas supply shall be cut off rapidly, namely cut off the main valve of inlet gas and air valve as well as cut off the power supply. (2) Explosion accident. The power supply shall be cut off rapidly, namely cut off the source of fire as well as cut off all gas valves and gas supply. (3) Isolate the side rapidly. Irrelevant persons are not allowed to enter in. Prevent smoke and fire strictly as well as prevent against accidents. (4) Flames shall be put out immediately and call the police rapidly. 8.3 Division of work for emergency treatment In case accidents happen, all the staff shall dive into the salvage. The main remedy measures shall be divided. The staff shall be trained usually before the accidents happen. According to the technology and managing situation of the gas station, the division of work as follows: (1) The stationmaster or administrator shall take charge of the treatment of the accidents. They will be in charge of divide the work, organize and conduct cutting off the gas, power, fire extinction and alarming, and then they will isolate and protect the site after the accidents are controlled. (2) The jockey and maintenance worker in the machine room are in charge of cutting off the gas supply and in accordance with the flow of the pipes, they shall be in charge of cut off the main inlet valve, gas pool and air valve. GRIEP and FREMS 74 March 20a4 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project (3) The electricians are in charge of cutting off the power supply. In terms or explosion or leakage accident, they shall solve it rapidly and decidedly. In terms of burning accident, they shall take the circumstances into consideration to solve it. (4) When burning accident happens, the gas-entrained worker and the entrance guard shall put out the fire by extinguisher. In case the flames are very difficult to put out, the gas-entrained worker shall call the police; when explosion or leakage accident happens, they shall be in charge of isolating the site and safekeeping. (5) Other people shall take part in extinguishments or safekeeping. 8.4 Emergency measures and emergency plan for major accidents In terms of treatment of abrupt pollution accident, "precaution crucial, safety first" of the basic guideline for the environmental protection shall be followed. Especially for those abrupt fire and explosion or other pollutions, precautions shall be put into the most important position as well as the management shall be enhanced. In order to put the guideline of "precaution crucial, safety first" into effect, control source of hazard, save injured persons, guide the residents to protect themselves, organize to withdraw and eliminate the harmful consequence, the preliminary plan for emergency must be built up. It needs the combination of constructors and social succor. The detailed suggestions as follows: 8.4.1 Emergency treatment for the engineering project The emergency treatment for the engineering project means that measures shall be taken to decrease the hazard of equipments, materials and management in the construction and production produced by the accidents. (1) Emergency equipment and material Emergency equipment and material shall include fire fighting and industrial health etc. Interior fire-fighting department of the project is compulsory fire-fighting organization, which staffs are not only producer but also firemen. The compulsory fire-fighting team must be organized well in the project. Organize them accepted train of professional fire-fighting, use and maintain the fire-fighting equipment in order to ensure that the extinguishments of the fire at the beginning would not be delayed, the accident would not be expanded as well as the good chance of extinguishments would not be missed. According to related statistics, good organization of compulsory fire-fighting team is one of the effective measures for accident protection. Technical equipment for fire fighting includes extinguishing agent and mini-type fire extinguisher etc for the project. The storage of extinguishing agent shall meet the requirements of fire fighting; at the same time, according to the requirements of fire fighting, the corresponding fireproofing facilities, tools, passages, banks and materials shall be prepared. GRIEP and FREMS 75 March 205 Envirommental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project On the other hand, it is very important to prepare productive hygiene facilities and personal protective articles. Productive hygiene facilities include industrial lighting, industrial draught, anti-vibration, noise-damping, anti-explosion, gas defense and anti-radiation etc. personal protective articles include the helmet, protective shoes, eye shield, anti-concussion plug, ear muff, helmet and protector of respiration etc. (2) Emergency treatment for site management Emergency treatment for site management includes formulation of plans and exercises, such as organization, system, division of work, self-aid etc. Organize to formulate managing system and technical measures for precaution of disaster and accident and carry into effect as well as make clear the requirements of emergency treatment. Formulate managing system of the safety of chemical dangerous articles and preliminary plan for emergency of chemical accident. Organize and train rescue team for accidents in the project, prepare necessary protective and rescue materials and equipments as well as specify a specially-assigned person to manage, inspect and maintain regularly in order to keep them perfect. Make clear the site directing organization and related system of emergency treatment as well as the responsibility to ensure that the direction is executed successfully.

The basic principle of emergency program is: alarming; estimating the level of hazard; rescuing people first and rushing to save life and property. At the same time of self-aid, it shall be reported to the leaders, such as Fire Fighting Bureau, Environmental Protection Bureau, in order to gain salvation. GRIEP and FREMS 80 March 209 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project 8.4.4.1 Fire-extinguishing and emergency program Quick fire extinguishing includes: (Detective the fire (2)Alarming system; Reporting workers on site and the emergency center (*)Self-aid of the workers in the factory, but only including trained workers Environmental protection includes: OLeakage detecting ®Report the leadership quickly ®Dispose of the leakage articles Under the circumstance of fire, it must contact with the fire-fighting department immediately to control the fire within the factory. Workers in the service station shall be accepted fire-fighting train and exercises usually so that they can inspect fire-fighting facilities and know how to use fire-fighting facilities. 8.4.4.2 Emergency plan A program of emergency plan and departure from the site shall be established based on combining with the leader department and fire-fighting department. The emergency plan includes two parts: emergency plan in the service station and emergency plan outside the service station. Emergency plan in the service station The program aims at protecting workers on site and disposing abrupt accident. The program is in the charge of the emergency center on-site. Emergency plan outside the service station The program aims at protecting surrounding people, property and environment. It is in the charge of local department, namely that introducing preliminary plan for emergency from social rescue. 8.4.4.3 Fire-extinguishing Under the circumstance of fire, the following actions shall be adopted voluntarily as possible according to the severity of abrupt accident: * Alarming; All workers on site shall be removed quickly except fire-fighting staff; * Inform the fire-fighting department immediately by telephone; * Try all the best to extinguish the fire. GRIEP and FREMS 81 March 208S Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project 8.5 Traffic Impact The bus depot operation will increase substantially traffic at the roads near the depot and increase the traffic loads and burden to these roads. The impacts however will only be restricted to early hour of 5:00 to 6:00 in the morning when the buses leave the depot and again 10:00 to 11:00 in the evening. At these two hours, there will be up to 400 buses in the area. The level of impact will be however limited by the following two factors: * The two access roads are major roads with relatively high traffic carrying capacity., and * At both of these two hjours of the day, the normal traffic is very low, leaving the road traffic capacity mostly to the buese. Because of these two factors, the impacts of increased traffic from the bus depot to the area roads are considered modest. Thre bus depot will erect billboards at the area roads to alert the dirvers of the perk bus traffic. In addition, proper traffic signals will be installed at the bus depot access gate to ensure traffic safety during those hours. GRIEP and FREMS 82 March 206O Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project 9 Impact Mitigation 9.1 Mitigation for sewage treatment and feasibility analysis In the project, sewage is initially disposed by each discharge outlet of the source of pollution, and then discharged into Jinshan Sewage Plant. It is clear from the analysis of the previous works that this project just maintains the sewage from the maintenance shop, which doesn't meet the requirements of discharging through the pipe. But for the security, in terms of the waste water of washing the automobile from the maintaining plant, sewage from the service center, water for washing and care of the automobile and sewage from the dining room, they will be discharged to Jinshan Sewage Plant to dispose after the process of oil-filtering, slag-filtering and air flotation. The process of swage treatment as follows: (1) Requirements of process design Early rainwater is mixed with sewage after pretreatment of oil-filtering and desilting, and then disposed by Jinshan Sewage Plant, at last discharged according to the first grade standard of The Integrated Wastewater Discharge Standard (GB8978-1996) (2) The process of purification treatment of sewage The flow process chart: GREP and FREMS 83 March 2063 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project Chart 9.1-1 Flow Chart of the Pretreatment Process for Sewage (3) Fecal sewage (:) Cesspool Early rainwater Rainwater collecting pool Oil-filtering and desilting Sewage from the dining-room Grid Sewage from the maintaining plant (©3 Oil-filtering pool Air flotation and oil removing (11) Sewage from the maintaining plant (lZ) Sewage after washing the automobile GRIEP and FREMS 84 March 204 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project (13) Sewage from the service station 04) Municipal pipeworks 05) Jinshan Sewage Plant After the above-mentioned process, the sewage can meet the third-grade standard of The Integrated Wastewater Discharge Standard as well as meet the requirements of adapter. 9.2 Mitigation measures for emission control Motor vehicle emission is the main source of air pollution. The treatment is difficult to execute effectively because it is non-point pollution, therefore greening is suggested to enforce and roadway on the bus depots shall be allocated reasonably as well as draught system will be built up so that waste gas could discharged through the exhaust well in the middle part of the bus depots and from the surrounding. The process of treatment of quick off-gas of automobile as follows |[pl ]: Smoke from the kitchen of the dining room will be discharged to the upper air through provided fuel after purification treatment by-static electricity. Oil smoke from the kitchen- Gas skirt of oil smoke- Static purifier of oil smoke- Draught fan-Pipe well for oil smoke- Discharging to upper air 9.3 Noise [p12]Mitigation Noise mitigation at the Maintenace Shop The high noise machines such as compressor should be installed at the northeast comor as this comor faces busy street (Pushang road). In addition, this machine should be placed in a separate room with sound proof design. This way it will reduce the noise to the masximum extent possible and in fact, if the compressor is placed in a sound proof room, the noise standard will be able to meet the applicable setandard at the property boundary and also the noise impact to the workers at the workshop would be minimum. Parking area noise mitigation The parking area will operate at limited hours only (22:00- 23:00 and again 5:00 - 6:00, the impact is only at this hours. The perimeter walls wil be erected at the perimeters. These walls will be 2 m high with solid bricks. As such, the walll will act as a noise barrier. However, as the buses leave the parking area, the noise barrier walls will not have any effect on attenuate the bus noise, as seen in Fig. 9.3-1 (day time) and Fig. 9.3-2 (peak hour). Therefore, other mitigation measures will be taken including: GRIEP and FREMS 85 March 205 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project * The bus drivers will be requested to drive slowly and minimize the needs for accelerations, braking, hornining and deceleration. * The parking will be carefully arranged and parking lot traffic will be planned in such as a way that buses at the north will leave first in the morning while buses in the evening will come back to the south side first in the evening. This way, the buses at south side will act as barriers and the noise impact time therefore will not be as high and not as long as the full hour in the morning and evening. So, impacts to the people in the two villages at the south may be reduced. * All buses will be well maintained and those exceeding noise standards will have to go through mandatory service. * The two villages will be relocated and resettled for the industrial partk development. Once this is complete, there will be basically no noise impact to sensitive receptors. * The future developments around the bus depot site will be well controlled and no sensitive facilities will b eallowed to built in the close proximity. Any future buildings will be constructed at least 25 m from the bus depot property. * Areas surrounding bus depot will be landscaped and trees will be planted which will help alleviate noise from parking area. 9.4 Mitigation for Hazardous Materials The potential abrupt accident hazard in the service station is the fire and leakage of oil. The operating rules shall be followed strictly in daily works and the safety MITIGATION MEASURESs shall be taken actively. The vigilantness of the staff shall be strengthened so that all hazard accidents could be avoided. The following measures shall be taken in design of the project and after the project is put into use. * The service station is designed as the first-grade fire proofed building, which effective safety protective distance must be more than 25m between other main buildings; the building shall be well draught. Naked light is not allowed around the building and heat insulation shall be prepared in the summer; oil tank and gas container shall be buried underground. * Explosion-proof electric apparatus shall be used in the service station according to related standard and rule. Iron tools, which can produce spark easily, and shoes with pins are not allowed to use in the operation. * Grounding device shall be prepared in the design of oil tank, transportation of oil, process of pumping up and filling. Static electricity shall be prevented to accumulate. * According to quality of stored oil and CNG, fire-fighting equipment shall be prepared and kept well performance. The employees shall be organized to drill usually so that they could use various fire-fighting equipment masterly. * Concrete shall be paved on the road of the service station so that cut off filtering of the oil in the accident; open-channel and open trench, which are connected with separation tank, which is established for the service station to GRIEP and FREMS 86 March 206 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project collect the water on the ground and leaked oil in the accident, shall be taken into consideration of the design for water supply and sewage works of the service station. Oil sick in the separation tank shall be cleaned up on time to prevent against major accident. * Necessary measures shall be taken to prevent against corrosion of underground equipment. Oil tank and oil delivery pipe shall have rot-proof coating in order to prevent against contacting with the soil directly; cathodic protection is adopted in the equipment in order to avoid the electric current entering into the soil from the equipment. * Concrete pit is set for underground tank; soil replacement method is used in the lower level of the pit, and clay soil, which is not easy to creep, will be used to backfill, which thickness is 2m. Mechanical or manual tamping will be adopted; Sampling analysis of local soil shall be prepared before the construction of the project. Monitoring well for groundwater shall be established within the service station. In case the quality of groundwater changes after the comparison project is put in operation, the corresponding measures shall be taken immediately. 9.5 Waste Management The bus depot operations will generate many waste. Besides the general municipal solid waste which will be sent to city's municipal landfill, there will be other industrial waste such as waste tires, waste batteries, scap metals from maintenance, waste parts from buses, waste oils, and others. Safe disposal of these waste is critical to ensure the minimum impacts from the bus depots operations. Generally, the following principles will be followed to ensure the sound diposal of these waste: * Waste will be recyled where it is possible to minimize the need for disposal and thus inevitable, impacts to the environment. Basically, scap metals and most of the bus parts from maintenance can be recycled and qualified contractors will be called upon to collect and recycle the scap metals. * Tires can also be recycled but recycling require qualified contractors and special technologies. * Batteris are hazardous waste. They should be stored in the bus depot first in a secured area. The storage area should be locked, well paved with secondary containment. The Fuzhou Hazardous Waste Disposal Center will be contacted and waste batteries should be sent to that facility for disposal or recycling where possible. * Waste oils are also hazardous. Again a secured onsite facility will be built with pave floor and secondary containment. The waste oil will be ultimately recyled by qualified contractors. * The bus depot will be develop a waste minimization program to minimize the generation of hazardous waste. GRIEP and FREMS 87 March 206O Enviromnental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project 9.6 Impact Mitigation Measures During Construction During the construction, the original landscape would be interfered by the discharge of construction sewage, surplus mud and the construction equipment and transportation vehicles would produce noise and flying dust. The environment around will be impacted if no proper measures. The environmental pollution caused by the construction and the prevention measures are described as follows: 1) Sewage The sewage on the construction site is from the equipment and material washing, drainage of groundwater during foundation construction, the oil-bearing sewage from the canteen of construction personnel and sanitary sewage and etc. The drainage from construction site contains much slurry. Without proper diversion and drainage measures, the sewage will cause flood on the site and interfere with the normal construction, and even run onto the road to interrupt the traffic. Furthermore, dispute might be caused if it flows into Gaizhai village or Geyu Village on south side. Therefore, proper measure for diversion and drainage of construction sewage shall be taken and the waster water from material and equipment washing may be reused after being settled. The sewage from the site canteen may be discharged only after dreg and oil filtration and the sanitary sewage shall be treated by means of septic tank prior to its discharge. During the construction of this project, the site management shall be strengthened to organize the civilized construction and strictly comply with the recommendation and measures above so that the environmental interference may be minimized and the harmonic progress between the city development and environmental protection can be ensured. 2) Noise The following mitigation measures have been proposed and will be taken during construction to reduce and minimize the noise impacts: * The contractors will be requested to adopt effective measures to reduce noise caused during the construction, and minimize the noise impacts. During the construction, Construction modes and construction time will be rationalized to reduce or avoid noise construction activities occurring during the most sensitive time, such as night time, class times and hospital operation time wherever possible. Use of piling machines at night (from 22:00 to 6:00) will be strictly forbidden and other noisy activities including heavy truck transportation, loading/unloading, beam lifting and stockpile of the materials will be carried out during the day time. If other noisy machinery and activities have to be used, they will be located to areas as far away from sensitive receptors as possible. If nighttime construction is absolutely necessary, the contractors will be requested to report the local environmental protection bureau as well as the PMO for approval (more on night time construction mitigation later). * Although three rounds of public consultation at the sensitive receptors GRIEP and FREMS 88 March 206 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project have been conducted during the EA for concerns of project impacts including night time construction, contractors will be requested notice well ahead of time the impacted public and communities and consult with the public for their concerns and opinions. The continued public consultation will be included in the tendering documents and made part of the contract obligations to the contractors, in order to receive public understanding and listen to their concerns and suggestion for mitigation. These mitigation measures, including public consultation for construction arrangement and night construction activities will be implemented prior to the start of the construction at the site to allow the public to express concern and the time to further design mitigation measures if needed. * The construction in the residential and school areas will stop one week prior to the annual national examination time (first week in July but the actual time may change in the next few years). All construction activities, including materials transportation and preparation, will stop during the actual exam time (3 days) to provide the best possible acoustic environment during this highly sensitive period. * For some components with a real long construction period, such as the foundataion and colum, special measures will be taken for the sensitive receptors nearby. There are several noise sensitive receptors around the sites, it will be arranged to construct during the school vacation to the extent possible. * Contractors will select and use the construction machinery with low noise as far as possible. Temporary generators will be banned in principle and the utilities will be requested to supply additional power to meet the construction needs. In case such arrangement with the utilities cannot be made, generator sets along the roads will be equipped with sound-insulation cover and located to be away from the sensitive receptors. Contractors will be requested to provide good maintenance to all their construction machinery so that they can be kept in good shape and best working conditions to minimize noise. * Construction time and construction sites will be rationalized. Working site with high noise will be far away from the noise sensitive receptor if possible. The access for construction transport vehicles in and out the site will be arranged at the side far away from the residential area. For individual construction site with serious impacts and near highly noise sensitive receptors, temporary sound-insulation enclosing structure or sound-insulation barrier will be set up. Alternatively, temporary noise barriers at the side near sensitive receptors will be built. For earthwork, contractors will arrange multiple excavators and trucks to work at the same time, and thus shorten the impact time. * Full time supervision staff will be retained by the PMO to supervise construction activities, particularly night time construction. Hand held noise meters will be used to measure noise levels at sensitive receptors such as hospital wards and residential buildings during the night construction periods. * With the close supervision of the PMO, the contractors will be requested to place a designated person for night time traffic management for construction vehicles. If necessary, proper training GRIEP and FREMS 89 March 20O9 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project and instruction from traffic police will be provided to minimize night time traffic congestion and hooting. * At each construction site where night time construction will be carried out, a public notice board will be put on display in a highly visible place. On this board, telephone number and contact number will be shown for the public to vent their concerns and complaints about the night time construction. All such complaints will be recorded, and investigated as needed, and then appropriate actions will be taken to address the concerns and complaints. * The concrete structures such as beams will be pre-fabricated in factories to the extent possible. Site concrete pouring for these elements will be minimized in order to reduce noise levels from these activities. As concrete pouring often requires continued operation, avoidance of site pouring is also an effective metod to reduce the need for night time construction activities. 3) Night time construction As ngiht time construction would result in particularly significant impacts to residents and other sensitive receptors, besides the above mitigation measures, the following special measures will be taken during the construction phase: * Urban residents and villages living within the potentially impacted areas will be noticed ahead of time for the length and noise intensity of the proposed night time construction. Information on why the night construction is necessary and mitigation measures to be taken will be provided to these urban and rural residents to obtain their understanding. These residents will be consulted for their concerns, difficulties, and suggestions for noise control prior to the commencement of night time construction. These concerns will be responded and suggestions adopted where appropriate. * Night time construction will be arranged in such a way to avoid school exam time (about one week in the summer) in the urban area and harvest time (about half month each in the summer and fall) in the rural area. These are particularly sensitve time when students need the good night sleep in preparation for exams and farmers for the heavy farming activities in the field. * Concreted mixer, power generated and other stationary equipment will be carefully placed to be far away from residential areas and villages to ensure no noise impacts from these machines. Where possible, municipal power supply will be utilized in construction including night time construction as diesel generators are extremely noisy and avoiding using them is the best mitigation. * Equipment with lower noise levels will be used for concrete pouring operations, which may required 24 hours non-stop operaiton; * Temporary noise barriers at the appropriate places may be erected to reduce the noise impacts at the night time. These areas may include noisy stationery construction machines and/or areas with sensitive receptors. * If necessary, the contractor will arrange *temporary accommodation away from the impacted areas for the extremely vulnerable people who need good night time rest, such as persons with illness and GREEP and FREMS 90 March 2009 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project elderly, * Notice boards will be erected at all construction sites providing information about the project, as well as contact information about the site managers, environmental staff, telephone number and other contact information so that any affected people can have the channel to voice their concerns and suggestions, and * Close supervision personnel from the PMO will be assigned to the construction sites during the period of night time construction to ensure that the above measures are taken and to respond to any un-anticipated impacts by necessary mitigation measures. All these mitigation measures will be included in the project Environmental Management Plan (EMP) which is a stand alone document used during the construction phase to enforce and supvervise the implementation of the proposed mitigation measures. And all which require the actions of the contractors will be included in the bid documents and later the contracts to ensure that these mitigation measures and actions will become contractual obligations for the contractors which can be enforced by the PMO and the environmental monitoring team. 4) Dust and exhaust gas (1) During excavation, drilling and demolition, water shall be sprayed on the loose and dry topsoil within the construction site to keep certain humidity and prevent from dust emission which shall be also applicable during backfilling when the topsoil is dry. (2) If the site is near Zhuzhen Fenggang Ancestor Temple, fence above 2.Om abound the construction site shall be set up. The main access on site shall be hardened and kept clean, and washing facility shall be installed at the exit. When the transportation vehicles driving out of the site, the guard and tires shall be well washed to avoid bearing dust and mud. During the construction, close mesh net shall be provided to prevent overflow of material, dregs and waste. Transportation of material and litter shall be in an enclosing manner, and overhead casting, careless loading and unloading is forbidden. The stockpile of construction earth and cement, lime and etc shall be properly covered or storage in warehouse. On site there shall a temporary enclosed litter stock for the waste and dregs that is impossibly removed immediately. Premixed concrete shall be used for the works with concrete volume up to 30m3 cast in one time. In case of mortar produced with bulk cement mixed in-situ, there shall be dust prevention measures taken for the site mixer. (3) On the site with demolition (site near Zhuzhen Fenggang Ancestor Temple) by method other than blasting, hard airtight fence over 2m shall be set up around and close mesh net shall be installed around the building to be demolished, so that the demolition is carried out in a closing condition and water spraying may be adopted during the operation. The * dregs and litter shall be cleaned and removed within 24 hours after the demolition and effective covering shall be provided for which may not be timely removed. When loading the dregs and litter, water spraying and dust decreasing measures shall be taken. For the area where no work is GRIEP and FREMS 91 March 200S Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project performed within 3 months after the demolition, measures shall be taken to prevent flying dust from the exposed mud by methods such as covering, ground hardening or simple greening. (4) During the construction with many oil fuel machines and equipment, dedusting and fume prevention devices shall be installed on fixed equipment windward working within 50m. 5) Construction camps Besides wastewater and solid waste, the construction will have other impacts from poor satinary and hygiene and poor and poor site management. The following measures will be taken during construction to prevent and mitigate the potential impacts: * The construction camp will maintain good housekeeping and good order. * Site will have a septic tank to hold and conduct preliminary treatment of satinatory waste before discharge * Site washrooms will be disinfected regularly * All workers will go through basic training for diease control, maintain sanitary and housekeeping requirements at the camp * Regular site education of workers for epidemic control and safe and hygiene lifestyle and habits, as well as basic hygiene and disease prevention knowledge * The camp will have on-site clinic to control and monitor any diseases * The camp will have an emergency plan in an event of outbreak of any epidenmics * All hazardous materials and waste will be stored in designated areas in the camps which are paved and weather-proof to prevent direct contact of dripping and leaking oil with bare soil. * The storage of fuels will have full fire prevention and fighting considerations. Emergency equipment for fire fighting and spill control will be provided at the site. * The construction camp area will be restored to its original state at the end of the construction and dismantling of the camp. Any soil and other contamination, if exists, will be cleanned through a remediateion plan. 9.7 Estimation of Costs for Environmental Protection The environmental investment of this project is RMB 1,897,300 Yuan including Oil-bearing wastewater, noise mitigaiton and canteen exhaust mitigation works, as shown in Table 9.7-1 below: GRIEP and FREMS 92 March 200O Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project Table 9.7-1 Estimated costs for EnvironmentalProtection S/n Item Amount (RMB 10,000) I Sewage treatment works 100.34 2 Noise mitigation 75 3 Canteen exhaust treatment works 14.39 4 Total 189.73 GRIEP and FREMS 93 March 2003 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project 10 Analysis of Alternatives Two alternative sites were initially proposed, evaluated and compared for the bus depot: one is located at the west side of Pushang Industrial Zone (Alternative I) and the othff at northwest of Wanbian Industrial Zone (Alternative II), all located in the Nantai Island, based on site investigations and other information gathered for both sites. The locations fo the two alterantive sites are shown in Fig.10-1. When two alternatives are compared to each other, Alternative I has demonstrated the following advantages: * Alternative I is well located in geographic center of its service area such as the dead distances can be minimized, and thus unnecessary consumptions of fuels, air emissions, noise and other adverse impacts from driving the unneeded distances. In contrast, Alternative II is located at a corner of the service area and thus longer distance driving to start and finish the service would be needed. * As bus depot would generate impacts from noise, air emission, vibration, visual impacts, etc., its location with respective to sensitive receptors is important to minimizing adverse impacts. Alternative I is located in industrial area with minimum sensitive receptors and the rural housing near the site will be relocated for an industrial park development under a different project. Alternative II site is near Fujian Yude Girls School. * Alternative I has much smaller resettlement need than Alternative II. * There are three direct access roads to for the Alternative I site with good connections with major city road network including the trunk roads of second and third ring roads. This will ensure its operation with minimum potential for public service and thus community disruption due to access or egress from the bue depot due to accidents on limited access roads. Altemative II has two access roads, meeting the minimum requirement. * The Alternative I site has all basic infrastructures on or near the site. This minimizes the needs for construction of the infrastructures which would cause adverse environmental and community impacts. More infrastructure construction is needed to service the Alternative II site. * The Alternative I site best complies with the city master plan and transportation plan and has sufficient area for a large bus depot of up to 400 buses, as needed for this facility. The Alternative II site is currently zoned as mixed commercial and residential area. Re-zoning is needed, therefore. Based on the above analysis and comparison, the Alternative I site is selected as the Jinshan Central Bus Depot site which has the least adverse environmental and community impacts in the two available sites. The EA and this EMP are prepared for this particularly site.

(A)the middle-agers and elders worry about that The interviewees are they would lose the source of income after land resettlers and local Geyu acquisition, so they require the government could villagers anvol village provide works to them or cost of living each with Jinshan Central month; Bus Depoting area (5) villagers report that resettled housings of minjiang xincun are unqualified on the original pushang road. The walls are cracked before villagers live in. The villagers can't find any leadership to lodge a complaint. Therefore they worry about the similar situation would be suffered by them. (©)local flower planters wrorry about the waste gas will pollute flowers and influence the quality and production of the flowers brought about by the GRIEP and FREMS 99 March 2009 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project construction of the parking area, so they suggest the construction shall be canceled or all the lands shall be expropriated.. (D)most interviewees worry about compensation for demolition could be in accordance with the related policies and whether the compensation could be paid in full to the resettlers; (2)interviewees worry about that they would lose 2 Gaozhai their source of income after land acquisition so that The interviewees are village their standard of living would be decreased; villagers ®)some interviewees worry that construction of the parking area would locate at the edge of their flower planting lands, which are beyond the range of resettlement, so waste gas of vehicles will influence quality of flower plantation. 11.5.1 Supporting opinions for construction of the Project Most of the public support construction of the Project. They consider that construction of Jinshan Central Bus Depoting Area could make transportation of local public conveniently, increase flow of people and promote local economic development. The construction of the project can make the surrounding land could be added value. Part of the public considers that although the construction of the Parking Area couldn't bring about tremendous active profit to the local district directly, they shall understand and support the requirements of the government's decision. 11.5.2 Issues worried by the interviewees Interviewees within the range of demolition have concerns upon following issues: I) Compensation after demolition; Most of interviewees worry about that they have not enough money to buy new hosing through compensation paid by the government and they couldn't pay expense of real estate management. The interviewees also worry about whether the permitted compensation of the government could be distributed each resettler, meanwhile they worry about that whether the calculation of the area of existing housing could be fair, therefore they require that the area should be shown by publication. 2) Living problem after demolition; farmers who lost their land worry about their source of income. Villagers within the intended Parking Area depend on the income of flower plantation, so they worry about that they couldn't do their farming at present and the standard of living will be decreased; especially the middle-agers and elders. 3) Parts of elders. live in the housings from their ancestors, so they worry about they have not enough money to buy new hosing. 4) The construction of the parking area will change the existing environment. Noise and waste gas of vehicles will bring about bad impact on quality of GRIEP and FREMS 100 March 209 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project surrounding environment, residential environment as well as the environment of flower plantation, at last the quality and production will be influenced. 11.6 Brief Summary on Public Participation Opinions 1) Most of the interviewees support Jinshan Central Bus Depoting Area Project; 2) Issues put forward by the interviewees and proposed to take into consideration during planning and design include: (D The site selection shall decrease demolished housings as possible to prevent against inconvenience to the public.

Environmental monitoring plan shall be made specific to different stages, including sample collection, analysis, data processing, environmental assessment, report preparation, etc. The purpose of environmental monitoring plan is to assess the effectiveness of various mitigating measures, respond as quickly as possible to environmental problems unforeseen in construction or operation periods, make policies on basis of data collected from monitoring activities, and improve or supplement environmental protection measures. 12.2.1 Monitoring points 1) During the construction period The main factor to be monitored during the construction period is the impact of noise on Gaozhai Village and Geyu Village. So, two noise-monitoring points will be set during the construction period, one in Gaozhai Village and one in Geyu Village. Either of the monitoring point will be set at Im from the window of the first row of residences. Monitoring will last for one day per three months, divided in two time sections - daytime and nighttime. 2) During the operation period The factors to be monitored during the operation period are noise, water quality and exhaust from motor vehicles. Four (4) noise monitoring points are set at Im outside the parking area boundary and one two (2) at Im from the window of the first row of residences of Gaozhai Village and Geyu Village facing the maintenance yard (one for each village). Six noise monitoring points in total. The purpose of water quality monitoring is to know the effectiveness of wastewater treatment facilities. So, water quality monitoring points are set the inlet, outlet and general water outlet. There are five water quality-monitoring points in total. The frequency of monitoring is one time every three months. Jingshan Public Transportation Center Parking area is equipped with facilities for monitoring exhaust of motor vehicles. These facilities are the matching monitoring facilities of the parking area and are used to monitor exhaust of motor vehicles that are of level-2 maintenance/inspection or above. The parameters to be monitored include smoke color (for diesel-fueled motors), HC, NOX and CO. The monitoring frequency will be determined as per the cycles of maintenance of motor vehicles. 12.2.2 Items, frequencies and durations Gujangzhou Research Institute of Environmental Sciences 106 Enviromnental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project For the items, frequencies and durations of monitoring during the construction and operation periods, please refer to Tables 12.2-land 12.2-2.

These data can reflect whether or not the future changes of environmental quality conform to the expected results and provide scientific evidences for formulating and revising environmental management measures in the future. In addition, these data are also helpful for establishing files and databases for environmental monitoring and for compiling environmental analysis and assessment reports. The specific requirements are as follows: 1) Content of report - original data (including parameters, monitoring points, duration of monitoring, environmental conditions of monitoring), statistical data, environmental quality analysis and assessment and signature. 2) Frequency of report One comprehensive report each quarter and one summary report each year. 3) Reports shall be (1) Sent to - Fuzhou Environmental Protection Bureau, World Bank and Constructor, and (2) Copied to the Environmental Impact Assessment Group for Fuzhou City Jinshan Central Bus Depot. Gujangzhou Research Institute of Environmental Sciences 108 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project 13 Main Conclusions 13.1 Necessity of project Urban public transportation is an important part of urban transportation. Public services are an important factor in measuring the quality of urban residents' life. Although, in recent years public transportation has seen great development, the planning and construction of urban public transportation parking areas, maintenance yards, hubs, and the first and last stops are not systematic. The land space for the first and last stops and stations/stops is also far from enough. All these factors are constraints for further development and improvement of public transportation and seriously affect the normal operation of urban roads. As per the Fuzhou City Public Transportation Rules and the scales of stations/lots requested for transportation areas, the planned parking areas are Jianxin Parking area, Xiushan Parking area, Nanerhuan Parking area, Fuxing Development Zone Parking area, University City Parking area, Xiayuan Parking area, Wenshanli Parking area and Maweikuaian Parking area. The total area planned for parking areas is 275, 000 square meters and can provide maintenance services for 1400 motor vehicles. So, it is decided by CCP Fuzhou Commission and Fuzhou Municipal Government to build Fuzhou City Jinshan Public Transportation Center Parking area to supplement and perfect the public transportation parking areas of the downtown area and the new area and improve the level and quality of public transportation services. 13.2 Baseline environment (1) Air The items to be assessed are N02 and PM10 and the standards for assessment are the Ambient Air Quality Standard and its secondary standard in the revision form. The monitoring points are Meiting Village, Panbian Village and Gangtou Village. As per the results of monitoring performed over these three points in the year of 2001, N02 and PMlO do not exceed the indexes and meet the requirements for secondary functional areas. This shows that, currently, the ambient air quality of this region is good. (2) Water The sections to be assessed are the Guokong sections of Beigang, namely Kuiqi and Aofengzhou. As per the division of functional areas for Fuzhou section of Minjiang River, the ambient water quality of Kuiqi and Aofengzhou sections shall be assessed as per the GB3838-2002 Class III water quality standared. Data collected from routine monitoring over Kuiqi and Aofengzhou sections in 2002 shows that these two sections meet the water quality requirements of Class III. So, currently, the water quality of Aofengzhou - Kuiqi section of Beigang, Minjiang is good. *(3) Noise There are six points for monitoring the ambient noise quality: 1# in Gaozhai Gujangzhou Research Institute of Environmental Sciences 109 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project Village, 2# in Geyu Village, 3# at the west side of the parking area, 4# at the north side of the parking area and 5# in the middle of the parking area. The noise environment of Gaozhai Village and Geyu Village belong to Class 2 and that of the west and north sides of the parking area belongs to Class 4. From Nov.10- 11, 2001, these 6 points were monitored for noise during the daytime and nighttime. The north boundary of the parking area is Pushang Road, but, according to the data of monitoring, currently, the traffic volume of Pushang Road is small and the ambient noise quality is good. The surroundings of the project are quiet and the ambient noise quality of the project is good. 13.3 Impact Assessment during the operation period (1) Air The main sources of air pollution of this project are the emission of motor vehicles and the oil-bearing smoke from the dining hall. The oil-bearing smoke prdocued by the dining hall, after secondary treatment, will be guided via the embedded pipe to the chimney at the top of the building, so it have little impact on the surrounding environment. Exhaust from motor vehicles is an area source. The main air pollutants in the exhaust of motor vehicles are NOX, CO and HC. The items affecting forecast analysis are N02, CO and NMHC. Non-methane total hydrocarbon source intensities can be calculated as per the regression equation for CTHC and CNMHC (The Relation between Total Hydrocarbon and Non-methane Hydrocarbon Exhausted by Urban Road Motor Vehicles by Deng Shunxi). The source intensity of N02 is NOX. Because sources of air pollution of this project are intermittently discharged, this project only forecasts the average concentration distribution on the ground in the axial direction in one hour when exhaust of the parking area is at the maximum. In addition, it also forecasts the degree and extent of the impact on ambient air quality. This project is located in a place where the ambient air belongs to Class II of the Ambient Air Quality Standard (GB3095-1996) and the secondary standard in the revision form. No provisions are made for the concentration of NMHC in the Ambient Air Quality Standard (GB3095-1996) and its revision form. So, assessment is specific to the impact of CO and N02 only. The result of forecast shows that, in peak hours of this project, in exhaust of motor vehicles, within 100m of the impact of N02 the concentration of N02 is 0.005-0.0713mg/m3, which is 0.2%-29.7% of the standard for assessment; within 100m of the impact of CO the concentration of CO is 0.0082-1.1020mg/m3, which is 0.082%-11.02% of the standard for assessment; the maximum impact value of NMHC at 100m around is 0.1779mg/m3. So, the N02 and CO from motor vehicles in construction of this project has little has little impact on the surroundings within 1 00m. Gujangzhou Research Institute of Environmental Sciences 110 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project (2) Water The drainage system of Jinshan Maintenance Yard uses a separate system for rainwater and wastewater. The wastewater from main production shops, such as the washing shop, maintenance shop and dining hall will flow to their own oil-isolating pool and, after treatment by the air-floatation system, is discharged into the urban wastewater drainage system outside the bus depot. The wastewater volume is about 357.7m3/d. All the wastewater will be treated at Jinshan Wastewater Treatment Plant and then be discharged into Beigang. The rainwater during the initial period is 88.4m3/d. This part of rainwater will be be treated via oil-isolation and sand-sedimentation to meet the Class III of Integrated wastewater discharge standard, then be directly discharged into the urban wastewater drainage system and be treated at Jinshan Wastewater Treatment Plant. This project will produce little wastewater. Furthermore, the wastewater will be treated at Jinshan Wastewater Treatment Plant before being discharged into Beigang. So this project will have little impact on the water environment. (3) Noise Following the completion of the project, noise will be increased from buses leaving and returning the depot, matinenance machine operaetion and other site activities. The predicted noise shows that noise at the north border of the site will meet the Class IV standard during the day time while noise in other sides will exceed the applicable standards (Class IV and II). The exceedance will be 2-16 dB(A) during the day time and 5-16 dBA() at night. The highest exceedance will occur during the early morning and evening hours when the buses leave and return to the depot which would see a high traffic volume of up to 400 buses per hour. 13.4 Assessment on electromagnetic environmental impact Fujian Provincial Radiative Environment Supervision Station conducted on-site power frequency electromagnetic surveys at 45 points at and around the project. The results show that at 1m from the wall of the substation the maximum power frequency magnetic field value is 1.89JiT. Under the trolly wire of 220kV, the maximum power frequency electric field intensity is 0.253kV/m, the maximum power frequency electric field magnetic induction intensity is 0.672JT. As per the chapter devoted to electromagnetic environmental impact assessment, Jianxin Substation (220kV) and its trolly wire (220kV) will not intervene with the interphones, GPS or CRT of the Dispatch Center. For the Dispatch Center, Waiting Hall and Workers' Dormitory, the environmental power frequency electromagnetic field intensity is lower than the assessment standard for impact of the power frequency electromagnetic field generated by hi-voltage transmission and transformation projects on the public. The impact of power frequency electromagnetic is zero and the power electromagnetic field intensity is lower than the strict international standard. So, there is little Gujangzhou Research Institute of Environmental Sciences 111 Environrmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project impact on the workers of the bus depot or on the public in the waiting hall. In the yard of this project, under the 220kV trolly wire and on rainy days, people can use umbrella without the fear of electric shock. The preliminary planaer layout of all the buildings, including the gas station, dispatch center, dining hall, waiting hall, etc meet the requirements of Electricity Facilities Protection Rules. Under the 110kV trolly wire, the path proposed to be moved, if hit by thunder, might endanger the gas station. The scheme using trolly wire shall be approved by the thunder-preventing authorities; otherwise, underground cables shall be used. Thunder-preventing drawings and facilities shall be uniformly approved and accepted by the thunder-preventing authorities. 13.5 Risk analysis and emergency scheme The main risks are leakage, fire disaster and explosion. Whichever kind of accidents happens, the consequences might be very serious. So, preventive measures shall be taken above all to prevent accidents from happening. Abide by the basic environmental protection policy of "Prevention Paramount and Safety First". At usual times, all the personnel of the station shall study related technologies, get familiar with the whole production process of the gas station and keep in mind the hazards of accidents, so as to make sure that everything is OK. At the same time, study and practice the emergency scheme so that once an accident happens, it can be handled according to the procedure in time. 13.6 Impact Mitigation (1) Mitigation measures for water pollution mitigation For this project, wastewater is preliminarily treated at the outlets of pollution sources before entering Jinshan Wastewater Treatment Plant. From above analysis it can be seen that, the wastewater of the maintenance and servicing shops of this project cannot meet the requirements for entering the pipe, but, for the sake of safety, oilVslag-separation and air floatation are used to treat the wastewater from the maintenance yard, gas station, service shop and dining hall to mee the requirements for connecting pipes, and then wastewater enters Jinshan Wastewater Treatment Plant. (2) Mitigation for air pollution Exhaust of motor vehicles is the main source of air pollution of this project. Being an area source of pollution, it is very difficult to be treated effectively. So, it is suggested to strength the greening efforts within the area, reasonably layout the tracks in the bus. depot, improve the ventilation system, so as to exhaust can be in time discharged via the ventilation wells in the middle of the bus depot and around. The oil-bearing smoke from the dining hall, after being purified by the electrostatic oil and smoke treatment, is guided to the top of the comprehensive building via the reserved chimney in the building. Gujangzhou Research Institute of Environmental Sciences 112 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project (3) Mitigation for noise As the buses leave and return in early and evening hours, the peak noise will occur in those two hours. The main mitigation will be to erect 2 m high solid walls as noise barrier to reduce the impact of noise to the surrounding areas. In addition, the bus speeds will be controlled, buses will be regularly and well maintained to minimize the noise intensity at the source. The most noise source, the compressor will be built in a sound proof shop. Future development will be controlled to prevent construction of any noise sensitive facilites near the bus depots. 13.7 Public participation This assessment involves two times of public participation. The results of public participation are: 1) The majority of the interviewees support the construction of Jinshan Central Bus Depot 2) Interviewees suggest that, while planning and designing this project, the following shall be taken into consideration: X The site shall be such that the number of buildings to be removed shall be minimized so as to avoid inconveniences to the local people. X Try to circumvent the tombs of the ancestors of the local people in planning. I In designing the bus depot, proper measures shall be taken to reduce the impact of noises and waste gases on the local residents around the project. 3) Interviewees suggest that, while constructing the project, the following shall be taken into consideration: Reasonably arrange the construction site. Concrete agitators shall be placed far from residential buildings. Try to shorten the construction period as much as possible. Slag/earth from the construction shall be properly dispose and shall not be dumped in nearby farm lands or rivers. 4) Interviewees suggest that, when removing and resettling local residents, the following shall be taken into consideration: ' Removed buildings shall be reasonably compensated. Hope the constructor can directly negotiate with and directly compensate the owners of removed buildings. - Suitable economic compensation is suggested to provide for the peasants who have lost the land so that they can keep their current living standards. This is positive for maintaining the social stability. - Impact on ancestors' tombs is considered in disigning. The current bus depot design shall back inwards so as not to remove the ancestors' tombs of local residents. E Properly settle old-age people to ensure that they can spend their remaining days safely. Gujangzhou Research Institute of Environmental Sciences 113 Environmental Impact Assessment for Fuzhou Jinshan Central Bus Deport Project 12.8 General conclusions Construction of Jinshan Central Bus Depot will contribute significantly to the irmpovement of the public transportation system in the city, particualry Jinshan District. As such, it will provide better service to the public and improve the standard of living for the citizens of the city. The centralized and properly designed bus depot in a more controlled manner will also allow removal the scattered small scale bus parking and maintenance facilities currently around the district .and thus eliminated adverse environmental and community impacts of these smaller and often poorly equipped parking and maintenance facilities some of which are located in the congested built up areas. The construction and operation of the bus depot would also bring some adverse impacts to the site and surrounding area, including primarily, permanent occupation of land and damage of vegetation on the land, increased noise, air emission from buses, visual impacts, wastewater generation, etc. With proper mitigaiton measures and the enviommetnal management plan in the design, ocnstruciton and operation phases, howver, these adverse impacts can be prevented, mitigated or otherwise compensated to acceptable levels.
