1.0 INTRODUCTION

1.1 Need for the Project

Along the continuous development of the national economy and enlarging regional economic gap, the West China Development, has been initiated by the central government to speed up the development of the economy in western and middle areas of China, as well as to maintain social stability, reduce poverty and promote the balanced development of the national economy.

Suining City is directly under the administration of Sichuan Provincial Government, located in south western China and under the West China Development program. The city is located in the central part of Sichuan Basin, and is the joint between provnical capital Chengdu and one of the four municipalities with a provincial status, Chongqing. The urban center of Suining situates at the confluence of Chuan-e (Sichuan-Hubei) Highway and Mian-yu (Mianyang- Chongqing) Highway. Da-cheng (Dachaun-Chengdu) Railway and Cheng-nan (Chengdu-Nanchong) Expressway go through the city. Such convenient condition of communications makes Suining a transportation hub and an important distributing center in middle Sichuan. Since the reform and opening up policies, socio-economic development has been fast. The population in urban area of Suining City reached 423 200 in the year 2002. And the constructed urban area reached 21.6 km2 from 6.1 km2 in 1985. The whole city has already developed into a regional comprehensive center city.

In 2004, to speed up the urban development of the city, Suining Municipal Committee of CPC and Suining Municipal Government divided the urban area into four administration districts: Jiangdongxin (new area in the east of Fujiang river) District, Nanba Industrial Park, old urban center, and Economic Development Zone. At present, the most part of the old urban center has been constructed, thus few land in the district can be used for new development for meeting the demands of ever-increasing urban population. In industrial parks, most part of the land is planned to develop industries, so lands for other use are relatively small. Therefore, the two areas, Jiangdongxin District and Xining (west of Suining) District, can play a role of carrier to develop the city. Of the two areas, Jiangdongxin District has worse conditions for developing due to lack of infrastructure and lands, and beyond the Fujiang river. So only the area, Xining District has the advantages for development.

It is planned to cover a land area of 3.51 km2, and to have a population of 52 500 in Xining District. As a comprehensive economic zone of the economic development

6

zones, there spread farmlands and few residential quarters in Xining District at present. Because of no traffic network available in the district, it develops slowly. If complete or perfect its traffic condition and infrastructure, rapid development will be achieved in Xining District then.

Xining District lies in the western part of Suining City, belonging to a sub-district under the Master Plan of Suining City. It is separated from the old urban area (urban center) by a canal, and adjacent to Guangde Temple and Wolong Park which are cultural relics at provincial protection level. This district covers an area of 3.2 km2, with a population of 35 000. The land of this district is flat, surrounded by green hills, with Guangjiyan River (a canal) running through. Mild climate, enough rain fall, clear season changes, together make this district a precious place for residence and business.

To sum up, the project of Xining District is very necessary and urgent. This project will also bring more jobs opportunities and incomes to Suining people. After the project is completed, investment and business environment will be improved, as well as the living standard of local people. The poverty problems also will be solved. The Development and Reform Committee of Sichuan Province authorized this project’s construction in October 2004, by the Document CFW No. [2004] 617.

Based on the requirements specified by Environmental Protection Law of the People’s Republic of China, Environmental Impact Assessment Law of the People’s Republic of China, Regulations of Environmental Protection Management for Construction Projects, Order No. 253 issued by the State Council of the People’s Republic of China, and Notice of Strengthening the EA Management Work of the Construction Projects Financed by Loans of International Financial Organizations, HJ [1993] No. 324 issued by State Environmental Protection Administration, State Planning Commission, Ministry of Finance, and People’s Bank of China, the Administration (Commission) of Economic Development Zone of Suining City entrusted Sichuan Research Institute of Environmental Protection* (hereafter SRIEP in short) to conduct the EIA work for Suining Environmental Improvement Project Infrastructure Construction in Xining District) Financed by the World Bank loan.

As soon as receiving the task, SRIEP sent its professionals to conduct the environmental reconnaissance, collect the relevant data, and produce the TOR for the EA of the project in July 2005. In August 2005, the TOR for the EA was reviewed by experts invited by Sichuan EPB, and then proved by Sichuan EPB with the Document of CHJH[2005] No. 344. After the TOR for the EA being proved, SRIEP conducted the monitoring on existing environment of the project area, and collected more relevant data according to the requirements of the TOR for the EA as well as the Document. Finally SRIEP produced the EIA Report of the Project.

1.5 Category of the EIA

1.5.1 Eco-environment

The project area is in Xining District of Suining City. The construction of the project will affect the local ecological environment, such as vegetation, etc. As the affected area is at the both sides of road construction within 300 m each, so the affected area is much less than 20 km2. The project construction will not obviously affect the biodiversity or damage the vegetation due to no rare and precious animals and plants in the area. And the physical and chemical properties of surface water will also not be obviously affected in the process of project construction. Therefore, the Category C

will be used to assess the bio-environmental impact according to《HJ/T19-1997》.

1.5.2 Ambient Air

The impact of the project on ambient air occurs mainly in construction phase, as the major pollutant is flying dust. By calculation, the equal-standard value of emission (P) is much less than 2.5108 , so the Category C will be used to assess the air environment.

1.5.3 Surface Water

The impact of the project on surface water occurs mostly in construction phase. The major sources of water pollution are production/construction wastewater and domestic/living wastewater. They are in small quantity and have a simple composition. After the completion of the project, wastewaters will be intercepted. So the environmental quality of local surface water (Category C water body) will

improve at certain degree. According to 《HJ/T2.3-93》, the Category C will be used to

assess the surface water environment.

1.5.4 Noise

The project area falls into Category B of Urban Regional Noise Standard (GB3096-

14

1993). The number of affected people will not change so much before or after the project implementation. Category C will be used to assess the impact on acoustic

environment according to《HJ/T2.4-1995》.

1.6 Scope of the EIAThe scope or range of environmental impact assessment is given in Table 1-9.

1.8 Key Points of EIA

Based on the further analysis of project as well as the proof of environmental protection measures, acoustic/noise environment, socio-environment, eco-environment and air environment will be the key points for assessment in construction phase, while regional acoustic/noise environment and socio-economic environment, especially the positive benefit of social environment, will be the key points for assessment in operation phase.

1.9 External Environmental Relations and Major Protected Objects

1.9.1 External Environmental Relations of the Project

The project area is located in Xining District of Suining City. It is in the west of urban center of Suining, being under the administration of economic & technical development zone. The vicinities of the project area are as follows:

Route/Alignment Design of Roads in Xining District:

The road network of Xining District is divided into 3 blocks with the boundary of Guangjiyan River which takes a shape of “S”. The three blocks are the east block, the middle block and the west block. Those blocks are connected by 3 trunk roads from east to west. While from south to north, 8 sub-trunk roads and branch roads are the frame of the network, with an average distance of 180 m. The minimum distance between road mouths is 90 m, and the maximum distance between road mouths is 900 m. The minimum radius of curve is 40 m, and the maximum radius of curve is 500 m. The maximum longitudinal slope is 5.94%, and the minimum longitudinal slope is 0.3%.

Intersections of roads are of plane pattern or at same elevation without central island or guiding island. At the intersection of trunk road and sub-trunk road, the vehicle entrance will be widen to three lanes so as to benefit the waiting vehicles when traffic lights turn red. Curbs at the intersection of trunk roads will have proper radius depending on the angle of crossing. Its minimum radius is 15 m, and the design speed is 30 km/h.

Insulation or isolation measures will be taken to separate the lanes of motor vehicle and bicycles or other man-power vehicles. Traffic lights will be installed at the intersections where the traffic flow is high.

2.2.1.3 Design traffic flow

According to Specifications for Urban Road Design, for motor vehicles which are not affected by plane interchanges, the potential vehicle flow is: 1640 vehicle/h when the design speed is 20 km/h; 1550 vehicle/h when the design speed is 30 km/h; and 1380 vehicle/h when the design speed is 40 km/h. The coefficient of road hierarchy is trunk road 0.8, sub-trunk road 0.85 and branch road 0.9, respectively.

The design width of Xingning Road is 24 m, among which 18 m of vehicle lanes for both motor-driven and manpower vehicles. There are 9 interchanges of the road. Their average distance is 960 m. By calculation, the affecting coefficient of interchange is 0.85, so the capacity of vehicle flow is 1120 vehicle/h. The two side lanes for manpower vehicles. Considering the affecting coefficient of manpower vehicle is 0.8, thus the traffic capacity of Xingning Road is 4032 vehicle/h.

27

The existing peak traffic flow rate per hour is 8.3%. With the increase of traffic, peak traffic flow rate per hour will be increase. It is forecasted that the peak traffic flow rate per hour will increase by 11% and 12% in 2010 and 2020, respectively.

The design of Xingning Road of 2 directions and 4 lanes can meet the demands of hourly peak traffic flow in 2029.

2.2.1.4 Building material supply conditions

For the construction of project, some natural materials, such as sand, pebbles, broken rocks, and slag are needed. Sand and pebbles can be taken from the river bed of Fujiang River. It has good condition to excavate, and the transportation distance is less than 10 km. For taking such raw material, specific permit should be got from local governmental department. Broken rocks and slag can be got from ground leveling of Xining District as well as earth excavation of Xingning Road construction. It is estimated that the transportation distance is less than 5 km.

2.2.2 Bridge and Culvert Component

2.2.2.1 Bridge and culvert works

Nine bridges will be constructed in Xining District. Among them, one bridge crosses Nanbeiyan River, and 8 bridges cross Guanjiyan River. The maximum span is 56 m and the minimum span is 28 m, with a width of 20 ~ 40 m. Two culverts will be constructed. The bridge and culvert works of Xining District are shown in Table 2-6.

2.2.2.2 Design schemes of bridge and culvert

For 1st Bridge, there are two schemes: one is arc-type bridge, and the other is single span bridge of prefabricated concrete T beam with simple supporting pillars. The later one is recommended. Such scheme has some advantages of low cost, short construction period, good driving condition, good image, no extra decoration, less interference on surrounding environment, and be beneficial for civilization construction activities. The 1st Bridge will be located at Nanbeiqu River which is the drinking water source conservation area of Suining City. The proposed single span bridge of prefabricated concrete T beam with simple supporting pillars will have no impact on the water body.

Bridges 2nd ~ 9th will adopt the design of single span bridge of prefabricated concrete T beam with box-type simple supporting pillars. Among them, bridges 3 rd, 4th and 8th

are located at the interchanges of roads.

In order to guarantee the irrigation by the two sides of road, culverts will be

28

constructed where Xingning Road goes. Most of them are of reinforced steel-concrete cover type, such design decrease the number of inverse-siphon facilities. Totally 22 culverts will be construction along Xingning Road. Bridge works of Xingning Road see Table 2-6.

2.2.3 Drainage Pipe Works

2.2.3.1 Existing sewage interception and urban drainage planning in Xining District

At present, no sewage intercepting facilities are available in Xining District. Domestic wastewater and industrial wastewater all discharge to Guangjiyan River. The existing WWTP only treat the sewage from the area south of Mingyue Bridge of the urban center of Suining City, and the area north of the WWTP. The WWTP adopts CASS technology of secondary treatment. It has a treatment capacity of 40 000 m3/d.

According to the detailed control planning of Xining District, separate drainage system is adopted in Xining District. That is, sewers receive wastewaters, and stormwater drains receive rainfalls. Each has its independent system. Stormwater will flows to the river nearby, while wastewater or sewage will go to sewers and then to wastewater treatment plants (WWTP). The treated effluent will discharge into the river.

According to Urban Master Plan of Suining City, a WWTP with a capacity of 10 000

29

m3/d will be built in Nanba Industrial District in the near future, and it will expend to 30 000 m3/d in the far future. The WWTP will treat the wastewater from economic development district and Qujiagou industrial division.

2.2.3.2 Stormwater drains works

There are two water bodies mainly in Xining District, they are Nanbeiyan River and Guangjuyan River (canals). Stormwater from roads of Xining District will flow to Guangjiyan River. Based on the principle that stormwater discharges into the nearest water body, the proposed stormwater drains will be laid along the slopes terms of the road elevation.

The total length of stormwater drains in the project area is 21 km. The trunk drain adopts reinforced steel bar concrete pipes with diameter of DN 400 ~ 800. Its starting point has a berried depth of some 2.0 m. Steel net with concrete will used to connect the pipes. Single grid type of drain inlet at the road side will be adopted as the stormwater inlet. The stormwater inlets will be connected by reinforced steel bar concrete pipes with diameter of DN300 mm. Steel net with concrete will used to connect the pipes. Manhole will have a slope of 1% to them. The branch drain of connecting the manhole adopts reinforced steel bar concrete pipes with diameter of DN300 mm too.

The manhole of stormwater has a circular or rectangular shape, and made of bricks. The stormwater manholes will be set based on the relevant specifications. Generally, the distance is in the range of 30 ~ 50 m.

2.2.3.3 Sewer works

A trunk intercepting sewer along the trunk road from east to west will be constructed in Xining District. And its branch sewers will also be constructed at the lower elevation area in term of the drainage area division. All the sewage will flow to a sewerage pump station which locates at an triangle area where the trunk road (40 m wide), Nanbeiyan River and Guangjiyan River intersect. The pump station has a capacity of 20 000 m3/d. Sewage will flow to the proposed WwTP in Nanba Industrial Zone through the pump station. It is estimated that the sewage quantity from Xining District is 16 400 m3/d. Table 2-7 gives a detailed information.

At present, Nanba WwTP has a treatment capacity of 30 000 m3/d. It will increase to 80 000 m3/d after the implementation of Phase II project. Although the completion of the proposed project of roads and drainage works will speed up the local development, the existing Nanba WwTP can still meet the demands of sewage treatment in a relative long period because the development in Xining District will have a step-by-step process of construction.

2.3 Identification of Environmental Impact Factors

The emission of pollutants occur mainly in construction phase of the project, while in operation of the project, traffic noise and automobile exhaust will be the major pollution due to the increase of traffic flow.

33

2.3.1 Identification of Environmental Impact Factors in Construction Phase

(1) Flying Dust

Flying dust generated from construction activities is one of the major reasons that cause the increase of TSP and PM10 levels in air. It has notable adverse effect on the ambient air in a small area, and reduce the air quality directly.

(2) Waste Gases in Construction Phase

In order to mitigate the impact caused by waste gases, during the construction period, asphalt, which is used for road and bridge construction, will be got from local asphalt melting plant of The Road Repair & Maintenance Brigade of Suining City in Chengnan Industrial Zone through purchasing. So it is no needed to set a special asphalt melting site for the project construction.

(3) Spoils and Debris

The Suining City has a landform of low hilly land. In order to comply with the relevant technical standard or code, road construction and river channel rehabilitation will involve the processes of high filling and deep excavation. It is primarily estimated that the earth excavation is 1 652 520 m3, and the earth filling is 959 80 m3. The earth excavation is larger than earth filling by 691 940 m3 . All the excavated earth will be used for backfilling, greening or landscaping.

(4) Construction Noise

The main noise sources are transportation vehicles, construction machines and power tools. It is estimate that the noise level is in the range of 75 ~110 dB(A). (5) Wastewater in Construction Phase

Wastewaters generated in the period of construction phase are domestic wastewater of constructors and construction wastewater. In construction phase, it is supposed that 500 of constructors and on-site managerial staff (maximum) will take part in the construction activities. The quantity of domestic wastewater in construction phase is some 50 m3/d. Construction or production wastewater from concrete mixing, equipment cleaning and site cleaning are the main wastewaters generated from construction activities. The main pollutant of those wastewaters is SS, being in the range of 1000 ~ 3000 mg/L. They are weak acidic, and contain small amount of oils.

(6) Land Acquisition and Resettlement

The project will occupy a total land of 2331.57 mu, among which farmland 1431.57

34

mu, and enterprises’ land 900 mu. (1 mu = 1/15, or 15 mu = 1 ha) The project will demolish total floor area of buildings of 143 420.78 m2, among which 845 65.53 m2 of farmers’ house (including 661 m2 of private stores or shops), and 58 855.25 m2 of enterprises and schools.

2.3.2 Environmental Impact Characteristics and Mitigation Measures in Operation Phase

In operation phase, the major environmental issues are noise and exhaust generated from automobile or motor vehicles running. In the meantime, it will have positive impacts of speeding up the urbanization, improving the investment environment, and raising the land value.

(1) Impact on Acoustic Environment

According to design data and analogical survey, the automobile flow of different type is given in Table 2-10 by calculation.

(3) Impact on Socio-environment

After operation of the road, the traffic condition in the urban area of Suining City will be improved, and it also will promote the development of the city. It will promote the economic development of Suining, improve the infrastructure condition of Suining, and improve the living standard of citizens, especially the villagers living presently along the road.

2.4 Necessity and Rationality of the Project

Xining District is in the Economic and Hi-tech Development Zone of Suining City. The eastern new district started late, with insufficient infrastructure facilities, and separated apart by Fujiang River, thus it develops slowly. The old urban area (urban center) has left little land for further construction, and cannot meet the need of growing population. Industrial District is mainly used for industry construction and leaves little land for other use, either. To quicken the development of Suining City, more people will flood into the city and so only the Development Zone could play the

36

role to solve the problem. While the Northern District of the Development Zone has less and less land for further development. Xining District, as a comprehensive economy district, is also developing slowly for traffic difficulty. Thus, Xining District will with no doubt develop faster after improving the traffic facilities and infrastructures facilities. This project goes on with the Detail Design of Xining District in terms of direction of route and technical parameter and the Master Plan of Suining City. The Master Plan (or Overall Urban Development Planning) of Suining City see Figure 4 of Annex.

Xinning Road lies in the western side of the Economic and Technologic Development District. It is an important part of the Western Ring Road. The construction of Xinning Road will enhance the relation of the divisions within the Development District, divert the south-to-north traffic in the center of city, and promote the development of the land on both sides of the road. The planed route is presently hilly terrain, including farmland, some pounds, which are suitable for road construction.

According to rough estimation, the project will need earth excavation 1 651 520

m3，earth backfilling 959 580 m3，earth abandoning or spoils 691 940 m3 . All the

spoils will be used for filling the bottomland or low land in greening project within Xining District. Gravels and broken stone bits can be obtained within a short distance in the district and so there is no problem for fetching and abandoning earth and stones.

There are no cultural relics and precious trees along Xinning Road. The major historical site within Xining District is the provincial preserved site, Guangde Temple. Because of the 70m distance from the temple to the road and a river between them, the construction and operation of the road will not have negative impact on Guangde Temple. The stability of the land along the road is good, with little bad terrain. So generally speaking, the environment exerts no obvious restrict. The project forms no obvious restrict to the development and environmental protection of Suining City.

The construction of public facilities in Xining District all adopts underground pipe network, and separate drainage system. Underground pipe network favors improving the whole city environment, sewage management and flood discharge. At the same time, the main artery or trunk road will play both the role of traffic passage and the landscape of the city, and the green belts on both sides of the road would be good place for walking. Thus, this project is feasible from the angle of environmental protection.

3.0 ENVIRONMENTAL SETTING

3.1 Physical Environment

3.1.1 Geographical Location

This project lies in the western side of Suining City, in the west of Kaishan East Road, extending westward to Liutongba, eastward to Nanbei River, northward to Guangde Temple, Wolongshan Park, Nanya Temple, and southward to a 100m distance of southern Guangjiyan River. In the past, this district belonged to the government of Xining Town, which included Dabanqiao Village, Jinmei Village, Yueshan Village and part of Bajiaoting Committee’s land. At present, it belongs to the government of the Guangde Street Office of Suining Development Zone. Suining City lies in the middle of Sichuan Basin, the middle reaches of Fujiang River, with its geographical

coordinates east longitude 1053422.5，north latitude 303033. The old urban

area of Suining City is 3km wide from east to west, 5km long from north to south, and its area is 15km2. It lies at the joint of Sichuan-Bubei and Mianyang-chongqing roads, 230km from Chongqing City, 180km from Mianyang City, 100km from Nanchong City and 170km from Neijiang City, and 80km railroad of Da-cheng (Dazhou-Chengdu) Railway is in Suining City. The old urban area was constructed along the western side of Fujiang River in the river valley plain, looking at each other with Hedong and Renli Towns, with Nanqiang Town in the south. The location of project area see Figure 4 of Annex.

3.1.2 Terrain, Topographical Features, and Geology

The surface configuration within Suining City is high in the western and north-eastern area, with edge above sea level around 500m and the peak 536.9m above sea level, Wenbi Mountain in Renli Town, and it is low in the middle and southern area, with lowest point 249m above sea level in the middle of Fujiang River at the joint of Lujia River of Shanxin Town in southeast and Chenjia River of Yongan Town of Tongnan; the average altitude of the whole city is 280~380m, with maximum elevation difference 287.9m and majority elevation difference under 100m. The massif within

the city winds and weaves, forming the shape of the Chinese character “川 ”. In the

middle area, Longdou, Hengshan, Juxianzhichi and Majia Town form a line of massif to divide the Fujiang River and Qiong River.

Suining City lies on the terrace of the right bank of Fujiang River, with topographical

38

features: high in the western and northeastern areas and low in the middle and southern areas. Geology Report believes that beside farmland, other rock and earth layers could be taken as natural base.

Xining District is upland with a single dyke, and its elevation is about 270~375, with small hills distributed within. The topographical structure of Suining City is simple, belonging to the Drape Belt in the middle of Sichuan Sedimentation of the Third Sedimentation Belt of New Huaxia Sires, and the surface structure is the result from Indo-Chinese Epoch to Himalayas Epoch. According to geological categories, the geological structure’s feature is about from east to west or from south to north and form north to east, mostly appearing in arc shape. Within the city area, there is no big rupture, and wide and slow drapes often in ordered anticline and syncline, except a secondary constitution—Tianshan Temple turbine-like structure upon the East to West Belt 15km away from Shehong County in the west. Most of the revealed layers of the city belong to Jurassic System, Cretaceous System, and Quaternary System.

Suining City is a region stricken by earthquake with an intensity of 6 degree, so the lifeline project and big high-layer public buildings will set up defense at 7 degree of earthquake intensity.

3.1.3 Meteorology

Suining City belongs to subtropical moist monsoon climate with features of mild, clear separation of four seasons, plenty of rainfall, longer frost-free period, more fog and clouds, and less sunshine.

The annual average temperature is 17.4℃. The extreme maximum temperature is 39.3℃, and the extreme minimum temperature is -3.8℃. The annual average relative humidity is 80%. The annual average precipitation is 1006.9 mm. The annual maximum precipitation is 1371.4 mm, and the annual minimum precipitation is 736.7 mm. The annual average evaporation is 967.4 mm. The annual average sunshine time is 1306.9 ~ 1471.8 hours. The average atmospheric pressure is 970.9 ~ 981.3 Pa. The annual average wind speed is 0.6 ~ 1.8 m/s. The maximum wind speed is 18 m/s. The predominate wind direction is N (19%), and the annual average calm frequency is 68%.

3.1.4 Waters

3.1.4.1 Surface water

Suining City has 46 creeks and rivers, interleaving everywhere. Xining District has rivers: Guangjiyan River, Nanbeiyan River and Fujiang River. Fujiang River

39

originates from Shanheyi on the southern side of Ming Mountain, is 670km long with acreage of catchments 34600km2 , runs from Xiangshan of Shexing County, through the center of Suining urban area, to Shanxing Town and out of Suining to join in Jialingjiang River. Within Suining City, the running distance of Fujiang River is 176km, its rain-gathering acreage is 3953km2 , year flux 14.925billion m3, average ratio of river way dropping 0.54‰, river width 80-200m with narrowest width about 40m, the maximum flood peak flowrate 9960 m3 /second, the average flowrate 128.5 m3 /s, and the minimum flowrate 60 m3 /s.

Nanbeiyan River is a canal which is a water diversion channel of Xiobaita Power Plant at Longfeng. It originates from the Huangniantuo of Fujiang River. Its total length is 26.6km, and 18 m of fall. The maximum flowrate 151 m3/s, its minimum flowrate 70 m3/s, the design velocity is 0.9 m3/s, maximum velocity 1.15 m3/s, ratio of water level change about 0.7, average water level above city zone about 2m. The water quality is good and is the source of drinking water of Suining City.

Guangjiyan River is an upstream canal of Fujiang River, the main surface water running through Xining District, and its main function is irrigation. Because Nanbeiyan River as the water source conservation area of Suining City, Guangjiyan River does not run into but under through Nanbeiyan River to join in Fujiang River. Within Suining City, Fujiang River is mainly used for industry, agriculture, irrigation, hydropower station, navigation and flood discharge.

3.1.4.2 Groundwater

Within the city zone, groundwater is mainly Fujiang River plain loose-rock small opening underwater type and red layer hill original rock cranny water type.

Fujiang River plain lose-rock small opening underwater is mainly distributed along the first grade terrain and flood plain. Water source mainly comes from rainwater, rivers and filtering water from rice paddy, gathering within the Forth loose layer in the form of small opening water. The groundwater’s burial depth is 3~5m, the extent of water level change 1~3m, waterpower grade 0.3%. Movement of groundwater is mainly vertical to rivers and slightly downward. Generally speaking, groundwater supplies the water of Fujiang River, and the water close to riverbank of Fujiang River is also the supply of groundwater. The volume of a single well on Fujiang River plain is 100~150m3/d, and that of a well near riverbank 2800m3/d.

Red layer hill original rock cranny water is distributed around within the city hilly zones: Zhongtongshaxi Group, Suining Group and Shangtongpenglai Town Group on Jurassic system. The major supply of ground water is rainwater and they are stored in reticulation cranny of air slake belt, constitution cranny and eroded cranny of leached belt. From the angle of groundwater distribution, the eastern zone of Fujiang River is rich in groundwater, while the western zone poor. Because of the flatness of layers

40

within city zone, with terrace obliquity 1~5degree, bits and pieces of water bearing layers, the surface water easily flow away and hardly gather underground and so the volume of groundwater is usually a little. Influenced by rainfall, the volume of groundwater changes greatly from season to season. In flood season, there is a great amount of groundwater; in dry season, a lot of wells and springs dry up. The burial depth of groundwater in eastern zone of the city is 20~30m, that of western zone 10~20m. The largest volume of a single well is 50~100m3/d, the smallest volume 10~50m3/d.

3.1.5 Vegetation and Others

From the angel of geographical location and climate condition in Suining City, the original vegetation belongs to sub-tropical evergreen broad-leave forest. Because of agriculture development, the original vegetation was replaced by capacious crop vegetation, with spotted small manmade woods, trees around houses, bushes, grassy slopes and stony wasteland.

The type of vegetation within city zone is very simple. Woods are often mainly made up by evergreen cypresses, with simple structure, and clear layers i.e. arbor layer, bush layer, and grass layer. Arbors including thistles and thorns, Coriaria sinica, thorn pear, lespedeza, transplant seedlings and so on; grass layer includes pachyrhizus vines, wild cotton, dandelion, cogon, blond hair grass, cotton grass, Kongyi grass, yellow congongrass, centipede grass, Dallis grass, dog-tail grass, thin stem grass, Iridaceae and so on.

The construction zone of this project is mainly farmland vegetation, spotted trees around houses and some bushes. No precious or protected plants were found distributed within the zone possibly influenced by project construction.

3.1.6 Natural Resources

3.1.6.1 Mines

Suining City is short of metal mines and rich in non-metal mines. Exploited and used mines are bittern, sand gold, shale, sandstone and so on. Bittern is one of the important mines within the city, is distributing in Penglai, Guihua, Paosheng and other places. Only in Penglai Town, bittern storage reaches 4.24 billion ton, 0.848 billion ton available for exploitation, which contains salt more than 70 million ton, and provides material for salt and salt industries. The storage of purple shale and pottery clay and sandstone is rich and used as the material of decoration brick and ceramic tile production.

41

3.1.6.2 Energy sources

Suining City has certain energy sources, which mainly are oil and gas. Moxi Gas Field has been proved up to have an acreage of 120km2, gas storage 25billion 120km2; in Penglai, Guihua and Jinhua, oil layers have been discovered and are lies in the Jurassic system layers of Daanzai Group and Secondary Alternated System layers of Xiangxiqun, Leitianjin Group, Jialinjiang Group and other places, and they are mainly gas fields. Huayingshan is rich in coal and has coal storage 18million ton. Waterpower storage is 0.5424million kilowatt. Biological energy ----sewage gas exploitation has great potentials.

According to statistics, within the urban area of Suining City there is a state-owned enterprise, with total output value of RMB 2.53 million in 2002, 99 collective enterprises with total output value of RMB 340.55 million, and 521 private enterprises with output value RMB 1697.89 million.

3.2.5 Traffic

Suining City lies in the middle of Sichuan Basin, and is an important hinge place of traffic. After the operation of Chengda Railway and Chengnan Highway, the traffic condition of Suining City has been greatly improved. Through railway, one now could reach Chengdu, Nanchong City, and Dazhou City. By highway, one now could reach Mianyang City, Chengdu, Chongqing and so on.

Suining City at present has 30.67 km roads, with an area of 750,400 m3 acreage and 2.5m2/person, occupying 10% of the land of the city, and the density of road network

is 4 km/km2（figures above includes only over 10m long road of old urban city） .

Compared with the national standard of roads and roads of other cities, Suining City’s roads are still in low level, needing more construction. Within the whole city, only Suizhou Road can be taken as a main artery with 40m wide redline, 7 km long from

43

north to south, shoulders almost all traffic flow of the city. So traffic jam happens frequently and restricts the development of the northern district of the city.

3.2.6 Education and Public Health

Suining City has 93 cultural centers and stations, 2 art performance troupes, 4 libraries, 213 medical and health organizations with 6071 sickbed, 523 people per sickbed, 5679 health technicians, 2360 primary schools, 133 middle schools, and one teacher’s training college.

There are protected sites of provincial importance, such as Lingquan Temple and Lingquan Scenic Spot, and tourist places such as Qi Mountain, Heming Mountain, Qi Mountain Academy of Classic Learning; tumulus such as Dengzhi’s Grave; old architectures such as Baifu Court, Bilu Temple; stone inscriptions such as Shifougou Statues of Tang Dynasty. The main historical site of Xining District is Guangde Temple in the middle and northern part of the district. The shortest distance between the temple and the designed road is 70m and there is Guangjiyan River between them.

3.3 Xining District

3.3.1 Survey of Social and natural environment of Suining District

Xining District is one of the economic and technological development zone of Suining City. It lies in the northwest of Suining City, west to Yueshanpo, east to Nanbeiyan River, north to First Water Factory of Suining City, south to Taohua Mountain, with a total area of 3.51 km2, and a population of 42000. As part of the economic and technological development zone of Suining City, its function is mainly to develop tourism, secondly to develop industry and goods transportation, and thirdly to afford people’s residency.

The main rivers in Xining District are Guangjiyan River, Nanbeiyan River and Fujiang River. Guangjiyan River is an upstream canal of Fujiang River, and its main function is irrigation.

Nanbeiyan River is a canal which is a water diversion channel of Xiobaita Power Plant at Longfeng. The water quality is good and is the drinking water source water of

44

Suining City. The vegetation in this district is mainly farmland vegetation with spotted trees around houses and spotted bushes, but without precious preserved plants discovered.

The major large enterprises in this district are Chuanzhong Oil and Gas Company and Keweida Company. Industries are most dispersed, such as a plant oil factory near Nanya Temple, a fertilizer factory and a pencil factory along Juxian Road, Chuanzhong oil mining area and an oil machine-mending factory within the area of Liutongba. In short, the industries in this district have no sordid basis, but only out of date buildings and facilities, and a small scale.

The residency lands of this district are the dormitory area in the eastern side of Chuanzhong Oil and Gas Company, with 6 to 7 storey resident buildings that have a certain facilities, resident lands with insufficient facilities dispersed in countryside and towns. This district has one middle school, 3 primary schools and a kindergarten and all are in small scale and have poor facilities. There is a branch station of the police office and no playground for residents.

The acreage ratio of road in Xining District is low. There is east-to-west Juxian Road, connecting Xining District and central area of Suining City in the east and reaching Daanju Town in the west. The Sui-yu Railway goes through the middle area of this district from north to south elevated all the way. There is South Train Station of Suining under construction.

3.4.3 Road Plan of Xining District

According to the overall plan, the city is designed to be made up of two districts and seven industrial groups. The structure of city transportation and strategies concerning its development should be designed in accordance with the nature and function of industrial groups. In line with rules, the road will be composed of two horizontal and two vertical roads.

The two horizontal roads are: the east-to-west artery in the north, which crosses the

48

downtown area and links the old city in the east and the new development zone in the west. In consideration of linking the overall road network and saving cost, the road will connect the old city through riverbank and a park bridge. In light with the plan, the park bridge will be widened by 30 meters in order to avoid traffic jam. The east-to-west artery in the south is a comprehensive key artery, which extends westward from East Kaishan Road to Xining District. It links former Juxian Road in the west and then the outer ring road of the city, and finally reaches the exit of Anju Town.

The two vertical roads are: a south-to-north landscape avenue will be built in the center of the district, which will extends from the logistic service section to the South Train Station, and links the 318 National Highway. The south-to-north road in the west of Xining district is an urban outer ring road. After expansion of the city, it will divert the traffic of the key artery to Suizhou Road. Therefore, the ring road will extend to 318 National Highway in the south, the North Train Station and the entrance of Chengnan Highway in the north.

Land use in the district will concentrate on the construction of arteries or sub-arties. The road network will have checked or free design. The road construction strategy of this project is consistent with that of Xining District.

3.4.4 Drainage Plan in Xining District

3.4.4.1 Drainage system

In line with the requirement of high starting point and standard, and the overall plan of Suining City, the district will adopt a system of splitting the flow of wastewater and rainwater. Individual pipes will be used for them. Rainwater will be directly discharged into the river nearby. However, wastewater will be pumped to a drainage plant for treatment and then discharged into river.

3.4.4.2 Sewer system

Intercepting sewers will be arranged east-to-west along the key artery. Wastewater will be piped to a drainage pump station, which is located at a delta area formed by Nanbeiyan River, Guangjiyan River and a 40m trunk road. Then wastewater will be pumped eastward to a proposed WwTP in Nanba Industrial Area. The pump station is designed to have a treatment capacity of 20 000m3/d.

3.4.4.3 Stormwater drains system

Flood intercepting ditches and drains will be adopted to receive and discharge stormwater.

49

Taking the topography into consideration, intercepting ditches will be built in the outskirts and around the programmed area to intercept floods and guarantee safety.

Inside the area, drains will be laid along the road to discharge stormwater into Guangjiyan River.

4.1.2.4 Analysis of assessment results

The assessment results from the calculation by using above-mentioned equations or formulas are given in Table 4-4.

The monitoring results show that at the 3 ricer cross-sections, pH, COD, BOD5, DO, NH3-H, and Ar-OH (volatile phenols) comply with Category C of Environmental Quality Standard for Surface Water (GB 3838-2002), except P&D (petroleum & derivatives). Petroleum and its derivatives exceed the standard value at the downstream cross-section of Guangjiyan River as well as the cross-section of Fujiang River. It is know from the analysis of monitoring results that the reason of P & D exceeding the standard is due to water pollution of Fujiang River and Guangjiyan River which receive industrial influents from the urban center and Xining District.

It is concluded from Table 4-8 that SO2, PM10 and TSP at point 1# and 3# comply with the Class B of Ambient Air Quality Standard (GB3095-1996). That means the air quality in Xining District is relatively good. But in Guangde Temple Scenic Area, PM10 and TSP exceed the stand, they can not meet the requirement of Class A of Ambient Air Quality Standard (GB3095-1996).

4.3 Environmental Monitoring and Assessment of Existing Noise Environment

4.3.1 Environmental Monitoring on Noise


For existing environmental monitoring, five points of noise monitoring were set at Guangde Temple, Xining Middle School, Wolongshan Park, Chuankuang dormitory, and a propose sewage pump station. Their layout see Figure 7 of Annex. After the completion of the project, Xining Middle School will move to other site, so the sensitive point will not exist.

4.3.1.2 Monitoring method

Noise measurement is conducted according to Urban Regional Noise Measurement Method (GB/T14623-1993).

4.4.1 Monitoring t on Existing Environmental Quality of Sediment


Three monitoring points are set at the inlet and the outlet of Guangjiyan River in

60

Xining District, and the point 100 m downstream of Chuanzhong Phosphorus Fertilizer Plant. The layout of those points is shown in Figure 8 of Annex.


The monitoring parameters for sediment are pH, total Cr, Pb, Zn, Cu, and Hg, totally 6 items.


The monitoring results are shown in Table 4-12.

61

Compared with the standard, Standard for Pollutants Control of Sludge Used for Farming (GB4284-1984), heavy metals of the 3 monitoring points of Guangjiyan River all meet the requirement of the Standard. That means, the sediment of Guangjiyan River has not been polluted by heavy metals.

4.5 Monitoring and Assessment on Existing Environmental Quality of Sediment

The project involves the dredging of Guangjiyan River. The dredged sludge or sediment will be used to greening in Xining District. From the monitoring results, heavy metals of Guangjiyan River comply with the requirement of Standard for Pollutants Control of Sludge Used for Farming (GB4284-1984). But according to the requirement of the W. B., Standard for Identifying Hazardous Substances — Leached Toxicity Identification, GB 5085.3-1996 should be used for analyzing harmful substances in sludge or sediment. Whether the sludge or sediment can be used for greening will be finally decided by the analytical results of GB 5085.3-1996.

Four monitoring points are selected to collect sediment samples. Samples will be analyzed according to GB 5085.3-1996. The 4 points are: 2 cross-sections of water sampling, the third one is located at the Guangjiyan River, 50 m downstream from the Phosphorus Fertilizer Factory, the fourth one is at downstream of the main outlet of domestic wastewater.

As the process of toxicity identification will last a period of time, the analytical results have not been got yet at present. As soon as the results are got, the relevant assessment on sludge or sediment will be done, and the proper disposal methods will be proposed and proved.

5.0 ENVIRONMENTAL IMPACT FORECAST AND

ASSESSMENT

5.1 Socio-environment Impact Analysis

5.1.1 Environmental Impact Brought by Local Urbanization

The completion of the proposed project in Xining District will dramatically improve the local traffic condition, speed up the process of urbanization, accelerate the development of third industry, mainly tourism and recreation, and help to form a better environment of inhabitation. But in the meantime, it will also arouse some environmental issues. After the completion of local planning, the population will be up to 52 500 from 42 000 nowadays, and the touring quantity of Guangde Temple Scenic Area will be up to 1000 persons /d. Wastewater and refuse generated from local residents and tourists will put a pressure or stress on the local environment.

Based on surveys, the existing wastewater treatment capacity of Suining City is some 40 000 m3/d, and it will be up to 80 000 m3/d when the expansion project (Phase Two) implementation. Therefore, it is considered that the development of local WwTP can meet the demands of local urbanization. At present, the refuse disposal capacity of sanitary landfill is 200 t/d. It can meet the demands of refuse disposal even if the increase of future residents and tourists through the relevant analysis.

Therefore, problems, which are arisen by the increment of environmental load due to local urbanization and tourism development after the project implementation, can be effectively solved through the planned facilities of wastewater treatment and refuse disposal. So no notable negative impact will occur then.

5.1.2 Impact on Local Land Use

This project will occupy 2331.57 mu of acquisition land, in which 1431.57 mu are in rural area, including 732.99 mu of paddy fields and 698.58 mu of dry land; and 900 mu are industrial area. (1 mu = 1/15 ha, or 1 ha = 15 mu) Land use in rural area is mainly flatland along the line and low hills. Main crops there are rice, wheat, corn and beans. According to statistics, this project will only occupy less than 1% of the land of

63

Suining city. Therefore, it has no obvious impact on agriculture of the area. Moreover, land use of this project belongs to that of the planned urban construction area. Farmland will be turned into urban area when the project is completed. However, the change of situation and function of land is acceptable and unavoidable. It complies with the requirement of land use in Xining District, and will not do harm to the overall land use of the area.

5.1.3 Impact on Living Quality of Relocated People

5.1.3.1 Impact in construction phase

(1) Resettlement and its impact on living quality of relocated people

This project will lead 14324 m2 of houses to be demolished, among them 84565 m2 are farmhouses (661m2 are private shops), the rest are industries. The municipal government will arrange resettlement caused by city improvement construction. According to analysis, at present, resettlement work of city construction in medium and large cities of Sichuan Province is successful. Related compensation policies also have been made in these cities. People of land acquisition and resettlement of this project will get compensation according to related policy of Suining City. It will not impact the living quality of relocated people.

(2) Impact on residents

The construction work will lead wires for electricity, telecommunication and broadcasting as well as some power transformer built on stilts and pipes to be demolished. However, the demolishment of wires will only cause short-time cut-off of power or communication. It will not exert much impact on production and life. Road construction probably will bring inconvenience to people’s life, learning, traffic or going-out. Noise, dirt and wastewater caused by the spread of pipes may do some harm to the environment along the line as well as people’s living quality.

65

Drawing an analogous analysis of city construction of the same kind, experts hold that the negative impact on people along the line could be minimized so long as related protective and alleviative measures are adopted, and the impact will be eliminated after construction phase.

5.1.3.2 Impact in operation phase

The operation of this project will improve urban living environment. Residents along the line will be direct beneficiaries; their living standard will be improved. Along with urbanization, the project will bring benefit to more people. In a word, it is helpful in improving living standard of residents there.

5.1.4 Impact on Urban Traffic

5.1.4.1 Impact in construction phase

Construction of this project mainly concentrates on the programmed area of Xining District. During road construction phase, a large number of vehicles will be used. In a time, traffic jam will be caused in nearby area. Moreover, development of this district lags behind other areas, and the distribution of population is not concentrated. Therefore, during construction phase, it is necessary to strengthen the management of building materials and reduce the piling of materials in construction site, to enforce control of vehicles. In this way, it would not do much harm to traffic.

5.1.4.2 Impact in operation phase

After construction, urban traffic will be greatly improved. The project will link industrial groups in Qujiagou and that in Yongxin. It will exert positive impact on the fast development of Xining District, on the improvement of road network. Therefore, it will improve traffic condition of the city.

5.1.5 Impact on Socio-environment

After the completion of roads, bridges and river course involved in the project, city traffic will be improved. It will reduce noise and the discharge of tail gas. The quality of local environment will be improved by comprehensive renovating of river course. In this way, a favorable investing environment will come into being. It will increase the charm and influence of the city; promote economic development of Xining District as well as Suining city

66

5.1.6 Impact Analysis of People’s Health

The project needs non-native construction labor force. This would cause the spread of contagious diseases, such as dysentery, viral hepatitis, tuberculosis and so on. Moreover, during construction phase, because constant flow of labors as well as their simple condition in the supply of drinking g water, board and living, peptic and respiratory contagious diseases also may become spread in the area.

It is hold that construction units should have the living place of workers sterilized regularly, and conduct checking and protective work regularly in collaboration with local epidemic prevention station. In this way, negative impact on people’s health during construction phase could be minimized.

5.1.7 Impact Analysis of Scenic Spots and Historical Sites

There is no historical sites or precious plants around Xingning Road. As to Xining District, the only one is Guangde Temple, a provincial historical site, located at the outskirts of the middle-north part of the district. The distance between the temple and the road is at least 70m, with Guangjiyan River between them. Therefore, road construction and its later operation would not do harm to the temple and its religious activities or tourism. It is not necessary to adopt protective measures.

5.2 Eco-environmental Impact Analysis

5.2.1 Impact Analysis of Water and Soil Losses

5.2.1.1 Impact analysis in road construction phase

(1) Analysis of the cause of water and soil losses

The project of road construction will occupy 2331.57 mu of land (1 mu =1/15 ha, or 1 ha = 15 mu). Previous surface cover will be removed. Meanwhile, the degree of horizontal slope will be controlled within 5%. Filling and digging during construction will cause water and soil losses and aggravate soil erosion.

(2) Impact analysis of the balance between the cubic meter of earth and stone as well as soil piling site and material site

Suining city is characteristic of low hills, rising and falling topography. In order to come up to technical standard of improving riverbank and roads, high filling and deep

67

digging is unavoidable. See table 5-2

renovation 4.73 217580 397320

Total 959580 1254200

From the table we can see, high filling and deep digging in the project are common. There is a large area of permanent slope formed during construction. Water and soil conservation must be concentrated on preventing water and soil losses of roadside slope. Meanwhile, we can see the amount of digging is far more than that of filling.

The amount of digging is 1651520 m3，that of filling is, 959580 m3 and of deserting

is 691940m3.

68

Building materials needed in the project are sandy pebbles and stone materials. The former can be fetched from the material site of Fujiang River, which is within a distance of 10km and has a favorable mining condition. However, it is necessary to get the approval of related department and go through formalities. Stone materials can be prepared from the site smoothing project of Xining District and the construction of Xingning Road. It is estimated that the distance is within 5km.

At present, the landscape project of Suining city plans to build 272310 m2 of Greenland and parking lots, 154500 m2 of riverbank Greenland and squires also will be built along Guangjiyan River. Earth produced in the project will be used to fill the low-lying land (about 310,000 m2) involved in the project of municipal administration. Silt produced in the renovation of river course can be recycled for farming or greening. According to preliminary analysis, earth produced in the project can be filled back for use in Xining District. However, earth produced for the time being must be piled in assigned site. Measures of preventing dirt, seeping and soil losses must be adopted in residue site. Residue can be discarded directly in rivers nearby, especially in rain season, in order to avoid water and soil losses. In order to prevent the stirring of dust in dry or windy days, it is necessary to cover the top of residue piles.

According to analysis, if measures can be adopted to conserve water and soil as well as bio-environment, such as building protective slopes, walls, drainage ditches or planting vegetation, water and soil losses can be controlled in those road sections or residue sites.

(3) Impact analysis of unfavorable topography

There is no unfavorable terrain in the site of the project. Such disasters would not happen as soft soil, collapse, uneven subsidence of riverbank, unsteadiness of roadside slope and water and soil losses.

(4) Detection of water and soil losses

Water and soil losses would happen in construction phase. In light of previous experience, soil erosion would be 3 to 4 times serious than its previous state if conservation measures are adopted during construction, or else it will reach 5 to 10 times.

The formula of detecting new water and soil losses during construction phase is:

Q=（E－E0）·A

69

where Q － the amount of new water and soil losses (t/a)

E － potential intensity of soil erosion (t/km2.a)

E0－ the intensity of soil erosion before construction， i.e. the constant

(t/km2.a)

A － the area of water and soil losses (km2)

The road slope of all section of the road is within 10%, so the intensity of soil erosion is calculated to be 3 times of usual state if conservation measures is adopted, or else the number will be 5 times. Moreover, the project will occupy 2331 mu of land. Soil sites and transferring material sites also will be set in different sections, which will occupy 20 mu of land. Therefore, the constant of soil erosion in Suining city will be the constant (E0) of land occupation. See table

5-3 Potential Water and Soil Losses in Construction PhaseType Unit Amount

t/a 14260

From Table 5-3, we can see, there is an annual increase of 14,200 tons of water and soil losses if conservation measures are adopted during construction phase. The intensity of erosion upgrades from ordinary to a severe situation. However, if conservation measures are adopted, the annual increase of losses is only 7130 tons, the intensity only upgrades from ordinary to a little high. Therefore, it is necessary to adopt measures to check water and soil losses. According to analysis, annual losses will be obviously reduced if construction is conducted in line with related technical standard, conservation measures is adopted and management is enhanced. In this way, negative impact on environment and hidden danger of the project could be alleviated or eliminated.

70

5.2.1.2 Impact analysis of operation phase

According to plan, ditches will be digged along road base in sections where digging has been conducted. The amount of digging and filling in those sections will be higher than that of the road with a height of three meters. The diamond frame of side slope will play a protective role; also vegetation will be planted in them. Road surface will be covered with asphalt and its side slope will be protected. Greenbelt also will be planted along the road and its side slope. Therefore, after being put into operation, soil erosion temporarily aggravated during construction will gradually get recovery or improvement.

After the embankment is completed, the previous topography will be changed. This will influence the distribution of water. However, sections or the distance between embankments will be set according to related standard to prevent floods. To sum up, water and soil losses in the area will be alleviated during operation phase.

5.2.2 Impact on Bio-diversity

5.2.2.1 Impact on bio-diversity in construction phase

Activities of construction workers and noises of building machines may disturb the living environment of field wild animals. Construction work will also bring harm to plants and crops along the road or along construction sites. According to analysis, the area along the line has been intensively developed; therefore it has a low level of bio-diversity. There are no definite precious plants needing special protection. Moreover, the construction will not last long. After completion, damaged plants will be recovered or replanted. Therefore, the construction work will not exert much serious impact on upland bio-environment.

In a word, the construction will have little negative impact on bio-environment and bio-diversity.

5.2.2.2 Impact on bio-diversity in operation phase

The completion of road and embankment will not split the previous field bio-environment; will not influence the living, hunting for food, reproduction and transmitting of messages of those wild animals. Meanwhile, the greening project conducted later will increase the habitat of wild animals. Moreover, the increasing change of certain part of bio-system will have positive impact on bio-diversity.

To summarize, the construction area is in the near suburb of the city, which has a high frequency of human activity. The existing structure of bio-system is basically consistent with human activities. Therefore, there is no obvious negative impact on

71

bio-environment and bio-diversity in construction phase.

5.3 Water Environmental Impact Analysis

5.3.1 Impact on Water Environment in Construction Phase

5.3.1.1 Impact analysis of embankment construction

A large amount of silt or sludge, magma and waste residue will be produced in embankment construction. If directly deserted into river or flood passage without treatment, they will block riverbed and disturb the water. Oil also will be used to run building machines during construction. Oil leaking or random discharge of waste oil into water would also bring pollution to environment. Moreover, water would also be polluted by solid waste residue discarded in it.

It is required that strict measures and management be adopted during embankment construction, especially through signing contract and supervising to check the discarding of waste residue or the discharge of waste oil.

5.3.1.2 Impact analysis of wastewater produced in construction encampments

During construction, workers are concentrated in construction sites; therefore, living wastewater will be produced. The number of workers needed is related to the scale of construction, the number of machine and season. Drawing an analogous comparison with other projects, it is estimated that 5 encampments will be set, with 500 workers in each site. 50m3 of living wastewater will be produced per day according to the standard of 0.1 m3/d per person.

Similarly, 100m3/d of production wastewater will be produced according to the standard of 20m3/d per construction sites. See detail in

Table 5-4 Wastewaters Produced from Construction Encampments Item SS (mg/L) CODCr (mg/L) BOD5 (mg/L) Petroleum &

derivatives (mg/L)

Quantity (mg/L)

72

Production wastewater

1000~3000 150 40 20~30 80

From the table above we can see, the parameters of CODCr, petroleum & derivatives and SS of the two types of wastewater exceed the values specified by Class A of Integrated Wastewater Discharge Standard (GB8978-1996). They will bring pollution to water body nearby if discharged without treatment.

It is required that measures be adopted to treat the two types of wastewater individually. As to living wastewater, it can be treated in pits and then used for irrigation. As to production wastewater, it can be recycled through precipitating or removing oil to avoid direct discharge.

The impact on water environment would not be obvious if protective measures are adopted in construction phase.

5.3.2 Impact on Water Environment in Operation Phase After the project completion, Xining District will have a separate drainage system, that is, stormwater is collected by drains and sewage is intercepted by sewers, each has its individual system. Stormwater flows to the river nearby, while sewage flows to the WwTP through sewers, and then discharge to the river after complying the relevant standard. The project components themselves (road construction, drainage pipe construction and river channel rehabilitation) do not have any impact on water environment. So in operation phase, the major consideration is whether the capacity of WwTP is suitable or not.

The wastewater quantity forecast of Xining District is 16 400 m3/d. Sewage will flowseastwards to the WwTP at Nanba Industrial Park through a pump station. The sewage pump station has a design capacity of 20 000 m3/d which can meets the demands of sewage flow.

At present, Nanba WwTP has a sewage load of 30 000 m3/d. It will increase to 80 000 m3/d after the implementation of Phase II project. Although the completion of the proposed project of roads and drainage works will speed up the local development, the existing Nanba WwTP can still meet the demands of sewage treatment in a relative long period because the development in Xining District will have a step-by-step process of construction.

5.4 Air Environmental Impact Analysis

73

5.4.1 Impact Analysis of Air Environment in Construction Phase

5.4.1.1 Analysis of pollution sources

It is not necessary to set specific asphalt extracting sites in road and bridge construction phase. Asphalt used in construction can be bought from a factory in the industrial area’ road maintenance section of southern Suining city. Therefore, the main sources of air pollution are dust and tail gas discharged from building machines driven by internal combustion engine. Dust mainly comes from the stirring of concrete, materials scattered during transporting of building materials, earth and stones as well as flying dust stirred from earth surface or the spreading of road face. According to the analysis of results got from monitoring, the most obvious impact on environment is from the flying dust produced in construction phase.

5.4.1.2 Impact analyses

Dust stirred by vehicles on the unpaved road will generate serious pollution. Flying dust has a small diameter of 10 to 20m. According to analogous analysis, 8% of the dust on unpaved road surface has a diameter less than 5m, 24% of them have a diameter of 4 to 30m, and 68% of them have a diameter larger than 30 m. therefore, dust is easy to be stirred on roads under construction. See Table 5-5

We can see from TSP results got form monitoring in construction site, a 50m area

74

from leeward to the road mouth will under the influence of dust. The density of TSP will fall sharply outside the area.

In a word, the construction will exert certain impact on air environment around the site. But the impact could be reduced to a degree the environment can endure as long as carrying out environmental monitoring, supplementing the rules of dust preventing and perfecting contract system. It is also necessary to put strategies of environmental management and project complementing into practice, especially in choosing proper address, carrying out dust preventing and removing, arranging transporting line reasonably, and so on.

5.4.2 Impact Assessment of Air Environment in Operation Phase

The main source of pollution in operation phase comes from tail gas discharged from vehicles. Pollution will increase along with the increase flow of motor vehicles. Pollutants from tail gas mainly are CO, CH, NOx. This project will take CO and NO2

into consideration.

5.4.2.1 Forecast model

When an automobile runs on a straight and plane highway, its exhaust can be considered as the dispersion of an equivalent linear source. Therefore, Gauss point source dispersion equation can be used to calculate the concentration of air pollutants.

By calculation, the traffic flow on various classes of road in rush hour is as follows. Based on the analogy survey & the design data, the traffic flow for light, medium and heavy vehicle is around 10:3.5:2.5.

b. Exhaust emission rate

By forecasting traffic in 2009,2019, 2029 (see Table 5-6 above), we worked out an estimated exhaust emission rate as table 5-7.

(2) Dispersion parameters

Resulting from traffic flow, the tail gas is both in vertical and horizontal dispersion; the air can hardly effect the dispersion. Yet traffic disturbance weakens as the gas becomes far away from the road. Thus the actual vertical and horizontal dispersion parameters 0z, 0y should take traffic flow disturbance and environmental impact into consideration. OZ, OY can be calculated by formula below.

where za — vertical dispersion parameters caused by environmental impact.ya — horizontal dispersion parameters caused by environmental impact.z0 — vertical dispersion parameters caused by traffic flowy0 — horizontal dispersion parameters caused traffic flow.

(3) Wind speed

Wind speed Uh observed from a wire system concerns with not only the alignment height of vehicle and road structure, but also with road traffic. If adopting the 10m-high wind speed got from weather observatory, it must be changed into the speed got from an effective height of 300m and complies with Schmit theory.

Uh = U10 (h/10) p + u0

where Uh — revised wind speed observed by the wire system (m/s)；U10 — the average wind speed at a height of 10m on local observatory

(m/s);

H — valid discharging source height (m)；P — verified wind speed index.

79

U0 —verified wind speed value caused by traffic flowing and discharging (m/s).

(4) The height of mixed layer

Discontinuous air current will arise between the upper and lower layer inside the atmosphere-bounding layer under both thermo and dynamic pressure, which then leads to the generation of mixed layer. The deeper of the mixed layer, the lower the ground gas density. The depth of the mixed layer is fixed according to The Technical Method of Formulating Local Air Pollutant Discharging Standard.

5.4.2.3 Forecasting result

We give a conservative calculation of contaminant density on the road based on maximum traffic flow in 2029. If the calculation meets the criterion, so do the other road sections besides rush hour. So we get the density value of CO, NO2 at different surrounding sites. See below Table 5-8 to 5-10.

5.4.2.4 Impact analysis of vehicle tail gas in operation phase.

According to years of vehicle exhaust monitoring in Sichuan, generally the background value of CO (existing value) is between 10% and 20% of the standard value. Forecasting shows that the highest ground concentration occurs at 10m height, daily concentration is 0.36 mg/ m3, 0.48mg/m3 per hour, which proves the CO concentration control still meet the standard after road comes into operation. Further more, the highest ground concentration for NO2, no matter by day or by hour, is the

81

same as that of CO. The forecast value is within the Class B of Ambient Air Quality Standard (GB3095-1996) .

Moreover, time still needed for traffic flow the reach rush hour in urban trunk roads. There is an annual increase use of gas for vehicles and stricter standard will be set for tail gas discharge. So gas discharge will be reduced. This project will not exert much negative impact on local environment. In a word, the forecasting value of NO2, CO still complies with the s Ambient Air Quality Standard. This indicates that the impact on air environment in operation phase would not be obvious.

5.5 Noise Environmental Impact Analysis

5.5.1 Impact analysis of noise in construction phase

5.5.1.1 Source of noises

Noises mainly come from building machines and trucks. According to survey, the noise brought by the digging machine, earthmover and road grader with full load, in terms of different distance from the construction site, is as follow table--

Table 5-11 Noise Level of Main Construction Machines unit:dB(A)Distance to

Bulldozer 86 80 74 65 64.5 62 60 56.5 54 50.5

5.5.1.2 Impact analysis of mechanics noise

According to the Boundary Noise Limits for construction Sites (GB12523-1990),the limit value in daytime is in the range of 70~75dB(A), while in the nighttime 55 dB(A). Table 5-13 shows the detail.

(1) At day noise beyond 40m can reach the standard value; at night, it can keep within the standard value at 200m from the site without the sound disturbing of road grader

82

and loading machine.

(2) Most residence and towns around the construction site is more than 50m beyond the road edge, so the impact at day will be not so obvious, but at night will be so obvious as to disturb surrounding residents.

Based on the above analysis, it suggests several management measures: Launching restraint mechanism on construction environment control and construction contract, to ensure the implementation of relevant noise prevention and control measures, such as forbidding fixing campsite near sensitive sites, and night work with high dB noise at sensitive sites area, thus the impact of noise will be greatly reduced.

a. Trunk road

85

The equivalent line for 70dB traffic noise at day is 50m away from the road center line, and relatively 60m and 70m in 2019 and 2029; the equivalent line for 65db in 2009 is 100m from the road center line, and relatively 120m and 150m in 2019 and 2029; the equivalent line for 55db noise value in 2009 less than 170m at night, and is 200m away in 2019.

b. Sub-trunk road

The equivalent line for 70db traffic noise at day is 40m, 50m, 60m away from the road center line respectively in 2009,2019 and 2029; the equivalent line for65dB noise value in 2009 less than 80m at day, and less than 100m in 2019 and less than 120m in 2029; the equivalent line for 55dB traffic noise at night are 150m away from the road center line respectively in 2009,2019 and 200m in 2029.

c. Branch road

The equivalent line for 70dB traffic noise at day is 15m away from the road center line in 2009, and 20m and 30m respectively in 2019 and 2029; the equivalent line for 65dB in 2009 is less than 35m, in 2019 less than 40m, and 2029 less than 50m; the equivalent line for 55dB traffic noise at day is less than 50m away from the road center line in 2009, in 2019 less than 70m, and in2029 less than 85m.

d. Impact on sensitive noise sites

Guangde Temple is located he west of #4 branch road and 80m away from the road center. It should be a sensitive site in the range of 100m away from the road center. It’s expected that after the completion #4 branch project on 2009, the daytime noise at temple gate would be 58.6 dB, and 52.6dB at night; in 2019 the daytime noise would be 62.0 dB, and 55.4 dB at night; in 2029, the daytime noise would be 64.6 dB, and 57.9dB at night.

Chuanzhong petroleum gas field dormitory is located at the east of #2 road, whose construction requires the demolishment of part of the dormitory. The retained new dormitory building is 50m away from the central line of the road. Noise impact on them after the operation of the projected road is as below Table 5-14.

According to the forecasting result, the traffic noise in 2009 both at day and night wouldn’t exceed the standard line for Guangde Temple; along with the increase of traffic flow, noise would exceed the standard line at night by 0.4 dB in 2019 and 2.9 dB in 2029. Yet the main hall and the meditation abode etc. are both beyond 150m away from the road center line, there wouldn’t be severe impact if relevant measures to be taken, such as tree-planting, prohibit of vehicle alarming at night.

Chuanzhong petroleum gas filed dormitory building would face more noise surpassing standard line at night, by 7.1d for the near term, and by 7.9 dB for long term. So it’s needed to set up protective screen at sensitive sites of the residence area where noise disturbing is the severest. To sum up, the noise for the near term would bring impact to the range of 150m sway from the road center line of both the main and sub trunk road as well as within 50m of the branch road of Xining district in road operation phase. Along with the increase of traffic flow, the impact would spread esp. at night for the middle and long-term future.

Summing up from the analysis, the noise impact can be reduced by monitoring vehicle noise, preventing the vehicle that brings over-standard noise, by setting up isolation belt, or planting more trees at sensitive sites where the impact is much more severe. It can even be reduced to the lowest level by strengthening transportation management, or forbidding alarming at night at road section surrounded by Guangde Temple and Chuanzhong petroleum gas field dormitory building.

In addition, train noise impact should be also taken into consideration in delimiting a controlled development zone since Suining-Chongqing express railway goes across Xining District. The suggested measure could be delimiting the controlled development zone of 50m at the two sides beyond the occupied area of the city trunk road, together with forbidding on building new settlements or new buildings for cultural, educational and hygiene purpose, for they are potential noise sources.

6.0 ANALYSIS OF ALTERNATIVES

For the four parts of the projects concerning road construction of Xining District, embankment construction of Guangjiyan River, construction of Xingning Road and construction of NO.1 Bridge, alternatives have been considered. Comparative analyses of these plans are following:

6.1 Alternatives for Road Construction of Xining District

6.1.1 Content of the Alternatives Alternative 1 (for recommendation): 21 roads with a total length of 25.26km,

including 3.41km trunk road, 14.5km sub-trunk road, and 7.35 km branch road.

Alternative 2, (for comparison) the alternative: roads with a total length of 22.99km, including 5.43 trunk road, 11.81 sub-trunk road, and 5.75km branch road. This plan needs digging tunnels and so needs a larger cost and increases the earthwork.

6.1.2 The Alternatives

Table 6-1 Characteristics of the Road Construction AlternativesA l t e r n a t i v

e sC h a r a c t e r i s t i c s

Alternative 1（recommended）

1. Using division layout, taking the advantage of the mountain, and so producing small earthwork and causing little alternation of the natural environment;2. Traffic route takes the advantage of the physiognomy, avoiding tunnel digging and reducing cost;3. This plan emphases the supplementing between tourism exploitation and district construction, and gives prominence to tourism culture.

Alternative 2(comparison)

1. Using “ two horizontals, one vertical” as the road frame of the district;2.”Two horizontals” includes one road trough the tunnel from the Park Bridge to the centre of the new district, and turning westward, and another road from Kaishan Road, bridging the northern and southern river embankments, to connect the old roads;3. The first road is the important passage connecting the district centre and the

89

A l t e r n a t i ve s

C h a r a c t e r i s t i c s

old urban area, and is closely related to the development of this district.

According to analysis, the alternative plan, which adopts the tunnel connecting Park Bridge and the center of the new district, will cover shorter road distance, but increase about 57 000 m3 earthwork and cost of about RMB 20 million. According to analysis, the alternative plan needs dealing with a great amount of earth, and goes against the balance of earthwork of the whole project. What’s more, according to the alternative plan, the new road connecting the old urban area will be in the protected area of Guangde Temple. After construction, the trunk road of the district will be near the gate of Guangde Temple, and so bring negative impact to the temple. Thus, if adopting the alternative plan, the view will be unsatisfactory from ecological esthetics point of view. According to the recommended plan, the No.4 Road of Xining District will be archaized street. Along the street, native trees will be selected to be planted with the supplement of Suining antique scenery, such as memorial archways, ancient lamps, and stone chairs. The pavement will be covered by materials such as light blue stone with ground embossment to express the antique culture and long history of Suining. This archaized street will be in harmony with the thousand year old Guangde Temple.

To sum up, from ecological esthetics and balance of earthwork point of view, it is recommended for this project to adopt No. 4 archaized street plan.

6.2 Alternatives for Embankment Construction of Guangjiyan River

6.2.1 Contents of Alternatives

The standard embankment model of Guangjiyan River will be vertical. Vertical embankment has three options in framework pattern and they are Gravity Type Paste and Gravel Embankment, Counterweight Paste and Gravel Embankment and Reinforced Concrete Cantilever Embankment. Stone bars will cover the surface of these three embankments. The details of these options are in Table 6-2.

To sum up, Gravity Type Paste and Gravel Embankment needs gravel which could be obtain within the district with an abundance of storage, good quality, short

91

transportation distance, convenient exploitation, available mature and simple technology, and produces less earthwork and needs less cost. Compared with Rolled Sand and Gravel Water-tight Slope Embankment, this plan causes smaller land occupation, and favorable for the drain-ff of floodwater. Thus, the recommended plan Gravity Type Paste and Gravel Embankment should be the most preferable, from the point of environment protection, construction technology and cost.

6.3.2 Comparative Analysis of Alternatives

92

After exploration of the site and negotiation with related departments of Suining, from the point of cost, road function and environment protection, we have done comparative analysis of the plans for Xingning Road construction. Details see Table 6-5.

Table 6-5 Comparisons of Alternatives of Xingning Road ConstructionAlternative Advantages Disadvantages

Alternative 1

(recommended)

1. it is harmonious with collective plan of the whole district；2.it could be a part of ring road and reduce the traffic pressure of northern city；3. It is convenient for exploitation of the land on both side of the road.。

1. Total cost will be high for total length is 3592m longer than that in plan 2.

Alternative 2

1. making use of old road about 2.6km (Mingyue Road near train station) and so saving some cost.

1Increasing traffic pressure of Mingyue Road will easily bring traffic jams.2.For mountainous west side and east side with Suining-Chongqing railroad, both side land has low use and so the function of city road cannot be fulfilled.

Alternative 3

1. total length will be 2513m shorter than that in plan 1

1. Although with shorter distance, The road will pass a lot of hills and so increase cost for earthwork and bring damage to natural environment;2. Both side land of the road will have low use and the function of city road cannot be fulfilled

According to analysis, among the three alternatives the recommended plan has the longest road distance, lowest cost per km, and is harmonious with the total design of the district and fully displays the function of city road, and both side land of the road can be used conveniently as part of city construction. In the sense of natural environmental protection, the recommended route will pass fewer hills and so produces fewer earthworks and less damage to natural environment. To sum up, the recommended plan is the most preferable, in considering protecting natural environment and fully playing the function of city road.

7.0 ENVIRONMENTAL PROTECTION MEASURES AND

THEIR ECONOMIC AND TECHNICAL PROOF

7.1 Measures for Soil Erosion Control and Ecological Restoration

7.1.1 Objectives

(1) Reduce spoiling devices of soil conservation as possible during construction and restore the devices spoiled.

(2) Surely control the soil erosion and restore ecologic state of the subgrade and

cutting along the road, keeping the function of soil conservation and ecologic reconstruction.

(3) Properly disposal the engineering spoils to prevent any collapse. Take measures to

control and restore the ecologic state. Plant trees on transfer stations or reuse it as farm land.

(4) Avoid any hurts to the Natural environment, organizations and human resulting

from soil erosion.

7.1.2 Measures to Control Soil Erosion

7.1.2.1 Measures to control soil erosion during design

When make decision of the pathway during design of a public works, keep the equilibrium of backfilling and excavation in the area as possible, reducing borrowing and spoiling of soil. The amount of excavation will much more than backfilling for this project, so no large sized borrow pit and stone pit are needed. The waste soil will be transported and piled at appointed spoil ground at Xining District of Suining City. The road project affects the soil conservation much. The following points must be noted when design:

1. Determination of the high wall slope for the subgrade

(1) For the subgrade relating truck sewer, when the height of backfilling is less than 8 meters, the high wall slope is 1:1.5. When the height of backfilling ranges in 8-16

96

meters, set a 1.5-meter-wide platform at the place of 6 or 8 meters. The high wall slopes are 1:1.75 and 1:1.5 for the lower and higher part to the platform respectively. When the height of backfilling ranges is higher than 16 meters, set a 1.5-meter-wide platform at the place of 16 meters. The high wall slope is 1:2 for the higher part to the platform. As for the lower part, it is the same as that when the height of backfilling ranges in 8-16 meters.

(2) For the cutting, the high wall slop can adopt different value depending on the rock property and excavation depth according to Table 7-1.

Table 7-1 Determination of High Wall Slope for Cuttings

Rock SortHeight of highwall

<20m 20-30m

Common soil 1:0.75-1:1.25

Interbedding of shale and sand slime

1:0.5-1:1.0 1:0.75-1:1.25

Sandstone and dolomite 1:0.3-1:0.75 1:0.5-1:1.0

2. E mbankment protection and eco-restor ing measures

(1) If the lateral distance between the side ditch and the edge of the road embankment of a filling section is more than 5 meters, plant arbors at the outer side of the side ditch and lawn plants on the side ditch.

(2) If the height of embankment filling is less than 1.5 meters, protect the slope with vegetation.

(3) If the height of embankment filling is from 1.5 to 5.0 meters, protect the slope with arch framing sward.

(4) At the places where are likely to flood, sides with hills, entrances or exits of bridge

culverts or embankment segments with enrockment road ， protect the slop

adopting grouting slabstone.

(5) For sidehill filling road embankments, contract the side slope. Set base-protection

97

of grouting slabstone with height less than 5 meters.

(6) For filling section with steep natural slope，build breast walls.

3. Protection of bad geological sectionProtection measures of bad geological section along the road: eliminating crags and protecting slopes with buildings.

4. Measures for r iverbank protection and ecologic restoration

(1) If the lateral distance between the side ditch and the edge of the road embankment of a filling section is more than 5 meters, plant arbors at the outer side of the side ditch and lawn on the side ditch.

(2) If the height of embankment filling is less than 1.5 meters, protect the slope with vegetation.

(3) If the height of embankment filling is from 1.5 to 5.0 meters, protect the slope with arch framing sward.

(4) At the places where are likely to flood, sides with hills, entrances or exits of bridge

culverts or embankment segments with enrockment road ， protect the slop

adopting grouting slabstone.

(5) For sidehill filling road embankments, contract the side slope. Set base-protection of grouting slabstone with height less than 5 meters.

(6) For filling section with steep natural slope，build breast walls.

5. Habitual measures of ecologic restoration for protection of cutting and embankment

(1) For excavation section on efflorescent soft rock such as mudstone and shale, adopt facing wall.

(2) For soil side slope, if the excavation height is less than 5 meters, adopt vegetation for slope protection. If the excavation height is more than 5 meters, protect the slope with arch framing sward.

(3) Set catch drain and drain at upper part and lower part of the side slope respectively. Plant sward at different level of facing wall. Plant sward or bushes on the top.

98

6. Borrow sites and transfer stations

Sands and gravels used by the project are taken from the Fujiang riverbed. Exploitation of sand and gravel from Fujiang River will not affect the environment due to its big reserve. Of course the exploitation should be reasonably arranged by the river administrative authority to avoid any effects on the flood draining or shipping.

A temporary transfer station is set for the project. The transfer station should not be set on flood drainage nor on fertile land. Any important public facilities must not be set in transfer station. Set a blocking dam before disposal. Soil and stone are piled up in trapezia shape with a proper value of side slope as 1:1.5-1:2, tamping it as possible. Flat the top with 2% extroversion crossfall and set catch drain for water drainage. Plant sward on the slope or restore it as arable land. Set blind pipes to drain the osmosis water and pack gravels at the outer edge. Pay attention to the regular shape of the transfer station when disposal so that mellow soil can be backfilled for restoration as vegetation or arable land.

For difficult ground with thickness less than 6 meters, embankment height less than 10 meters, subsidence less than 0.5 meter and stability factor less than 0.95, set

slabstone drain，or back pressure berm，or geogrid, or comprehensively combine the

technologies above to meet the requirements of subsidence and stability for the embankment.

7.1.2.2 Soil conservation work during construction

Suining City locates in hilly area with terrain out of level. To reach the regulation standard of roads and riversides, high backfilling and deep excavation in local parts are inevitable. The excavation, backfilling and spoils are 1651520, 959580 and 691940 m3 respectively. The spoils are mainly used for virescence and flatting ground of some projects else. Temporary spoils of the project must be piled up at appointed transfer station, taking necessary measures for soil conservation.

(1) The construction work of embankment and subgrade should be arranged reasonably according to the local weather conditions, being suggested to do from October of the year to May of the next year and to build facilities for side slope protection and drainage before rainy season. Cover the excavated section with plastic film in raining days. The length of drain ditch is 2 km.

(2) Strengthen the administration and conduct the construction strictly according to the design. Don’t enlarge the scope and quantity of the transfer station and borrow site at will.

99

(3) For construction of roads or riversides, fences of geotextile should be built to prevent the construction materials or spoils from falling into the river.

(4) When the subgrade is constructed, first of all, pile up the surface arable soil in the working area temporarily. After completion of the construction, use it for virescence.

(5) Engineering of subgrade protection should be constructed as soon as the subgrade is formed so that it can be functional as soon as possible.

(6) Torpedoing is forbidden for soil hillside closing to residential areas.

(7) Re-plant crops or vegetation on used temporary construction roads.

(8) Restore temporary transfer stations as arable lands or plant ornamentals or swards as soon as possible.

7.1.2.3 Measures for soil conservation during operation phase

During operation phase, the company that constructs the road should regularly check the controlling effect of soil erosion for protection works of subgrade as well as the transfer stations. Fit any problems found immediately to ensure full function of the protection works for soil conservation. At the same time, go on and consummate the virescence of roads and riversides.

7.1.3 Proof of mitigation measures

The measures mentioned above for construction as well as eco-restoration are based on industrial specifications relating road design, laws relating soil conservation and technical specifications concerned. They cover the entire measures, being operable and guiding. The measures have been proved effective and functional on controlling soil erosion and eco-restoration in Sichuan Province. At the same time, the measures of soil conservation and eco-restoration have protective functions to the foundation and safety for main works of the road. Namely multi-benefit can be got from single project to save the investment. The scheme of soil conservation in this project has been approved by the Conservancy Bureau of Luzhou City.

Therefore, the measures of soil conservation of the project are feasible economically and technically.

7.2 Measures for Water Environmental Protection and Their Proof

100

7.2.1 Controlling Objectives

No pollution of aquatic environment resulting from the project construction.

7.2.2 Protective Measures for Water Environment

1. Set desilting tank and filtration tank at the wastewater discharging place of the construction site. Reuse treated wastewater as possible or discharge them according to the standards. Regularly transport out the domestic sewage as fertilizer. Recover waste oil in sort using special containers for sale.

2. Only the wastewater that strictly meet the requirement of Class C of the standard GB8978-1996 are allowed to flow into the main pipeline.

3. When construct the embankment, control oil expense and recover solid wastes by using working coupon to avoid any discharging into river.

7.2.3 Assessment of the Measures

The main pollutants in wastewater at construction sites are SS and petroleum and its derivatives. By taking the measures mentioned above, the wastewater can be treated to reach standard with low cost. By recovering the waste oil, not only pollution is controlled, and also some benefits can be got from the recovered resources.

When construct the embankment, control oil expense and recover solid wastes by adopting working coupon. Intensify the administration of the construction to avoid polluting the drinking-water source. Essentially, it just means carrying out clean production and controlling pollutants production by “offering cleaner service”. Bridges are constructed adopting the technology of cantilever cast resulting in less oil expense and less pollution production.

The measures have strong pertinence to alleviate impact of the project in different phase on surface aquatic environment. They emphasize administration and adopt clean production process. Control pollutants production from the very beginning during the whole production. Strengthen risk precaution during operation. The assessment concludes that the measures comprehensively reflect the result of environmental administration and clean production, which have advantages of low cost, minimum pollution of aquatic environment by the construction of the program. The measures for protecting surface aquatic environment are feasible economically and technically.

101

7.3 Measures for Air Environmental Protection and Their Proof

7.3.1 Controlling Objectives

No bad impact of the project construction on the environment for people’s study and life as well as the air quality along the line. No decrease of the functional degree of the local atmosphere along the line resulting from operation of the road.

7.3.2 Measures of Environmental Protection

7.3.2.1 Measures of environmental protection during construction

(1) Don’t select construction encampments upwind or closely to the area where many people live in. Set temporary transport line far from sensitive places. Construct fences around the construction encampments and main works.

(2) Set dedusting facilities at construction sites and concrete preparation sites.

(3) Construction encampments, material sites and vehicle roads should be dedusted by sprinkling.

(4) Dedust for construction in windy days by sprinkle.

(5) Strengthen administration of transporting vehicles and strictly prohibit the vehicles overloading and falling sands, stones, cement and spoils down to the roads. The loaded vehicles must be covered with paulin when it’s windy.

7.3.2.2 Measures of environmental protection during operation

During operation, control the automobile off-gas by strengthening discharge monitoring and by virescence. At the same time strengthen administration of vehicles to transport construction materials and spoils and strictly prohibit the vehicles to overload and fall materials down to the roads.


Alleviate the bad impact of the project construction on schools by means of optimum design, say, reasonable selection of location for construction encampments and

102

transportation lines. At the same time, strengthen the environmental administration of construction to control flying dust during construction and transportation. The control of atmospheric pollution is also conducted through intensified monitoring during the road operation.

The measures mentioned above have high pertinence, which emphasize strong control of flying dust during construction and monitoring off-gas and garbage transferring stations during operation. And the measures emphasize optimum design, environmental administration and sources control, which has advantages of low cost and significant effect. The protective measures of atmospheric environment are feasible economically and technically.

7.4 Measures for Noise Control and Their Proof

7.4.1 Controlling Objective

No bad impact of the project construction on the environment of people’s study and life along the line. No worsening of the acoustical environment in the present or planning residential area at two sides of the road resulting from operation of the roads.

7.4.2 Measures to Noise Control

7.4.2.1 Measures during construction

1. Don’t select construction encampments closely to any schools or area where many people stay.

2. Set temporary transport line far from protective objects.

3. During constructing main works of the road, construction at night near sensitive area is forbidden for the types of work with strong noise.

4. Strengthen individual protection of working sanitation for machinery operators.

7.4.2.2 Measures during operation

1. Set sound insulation such as sound barrier, sound insulation wall or that of virescence when construct the main works according to “three synchronizations”.

2. Instrument, coordinate and consummate the establishment of regulations in detail concerning the municipal public zone along the line where are about to be exploited,

103

based on environmental protection. Properly adjust the redistribution of the municipal public zone along the line where are about to be exploited based on layout programming.

3. Intensify the monitoring of vehicle noise. Forbid horning by setting warning symbols near sensitive places.


During construction, alleviate the impact of noise on sensitive places by optimizing design and strengthening the environmental administration, which have advantages of low cost and significant effect.

During operation, implement noise treatment step by step based on different operative phases to dramatically reduce the primary one-shot cost and prevent any blind treatment resulting from uncertain factors in future. Consequently, it reflects a harmonized development between the urban construction and the environmental protection to avoid passive situation of pollution first and then treatment, saving the noise treatment cost.

In conclusion, the measures to control noise during both of construction phase and operation phase are feasible economically and technically.

8.2 Resettlement Action Plan

Presently, the compensation and resettlement of land acquisition and demolition within Suining Municipality is carried out in accordance with No. 21 order of Suining people’s municipal government Enforcement Measures of Compensation for Land Acquisition and Demolition and Resettlement of Peasants’ Houses Within Urban Planning Areas in Suining Municipality, and No. [2003] 60 order of Economic and Technical Development Zone in Suining Municipality Notification on Problems Relating to Compensation for Land-acquisition in Urban Planning Areas and Demolition and Resettlement of Houses on Rural Community’s Land . No. [2004] 62 order of Economic and Technical Development Zone in Suining Municipality Advice on Further Improving the Work of Peasants-turned Non-peasants’ Subsistence Allowance Guarantee Within the Areas of Unified Land-acquisition stipulated the standard of resettlement allowance of the affected people. The demolition and resettlement compensation in this project will comply with the above-mentioned rules and specific standards.

8.2.1 Demolition and Resettlement Plan of Peasants’ House

The resettlement place of relocated peasants’ houses will be in Guangde Resettlement Quarter. The resettlement house area of newly built in the first phase has reached 60,000 m2, and that of the second phase is planned to be 40,000 m2. The first phase began construction in April 2004 and was scheduled to complete by the end of 2005. The second phase will begin construction as soon as the first phase houses are

110

finished allotting. The resettlement houses of the first phase will directly gratify the need of resettlement of the demolished houses involved in this project; that is to say, the resettlement families need no transition.

8.2.2 Demolition and Resettlement Plan of Commercial Shops

For the commercial shops involved, those with business licenses, ratification documents of the projecting and administrative departments in charge, having gone through tax registration and formalities of change of land-use nature, and having been in actual production or business practice for over one year, can be allotted non-residential houses in proper places and given resettlement allowance in accordance with the resettlement compensation measures for non-residential houses during demolition of urban houses. Those who cannot be directly resettled and need transition by themselves will be given monthly subsidy for non-production and non-business.

Those with no business licenses will be given allowances according to residential

houses, and subsidies of 10 Yuan/㎡ for their business facilities. As to the standards of

demolition allowance for business houses see Table 8-2.

8.2.3 Relocation and Resettlement Plan for Enterprises

This project involves 20 medium-/small- sized enterprises, being affected to different extent, and in different scope. Besides that, this project involves the construction of road network in the district. All the land in Xining District will be gradually used for

111

construction after the completion of road network. Therefore this plan will carry out full compensation or resettlement for some affected enterprises, considering the follow-up development and exploitation.

Four types of compensation and resettlement are planned.

⑴ Cash compensation: For the situations when a few houses are affected, for example, only gatekeeper’s house or enclosing wall is affected.

⑵ Cash compensation: For the situations when an enterprise does not plan to re-open, such as the bankrupt one.

⑶ Cash compensation: For the situations when the enterprise owner will decide and choose the way of enterprise’s further development, such as choosing new trade, or the site of enterprise in another district or city.

⑷ Replacement of site of enterprise: For those who still decide to rebuild the enterprise in the development zone in Suining Municipality, the Development Zone will give corresponding land in the Industrious Zone to the resettled enterprises, and the demolished and resettled houses will be compensated for the enterprise to build new buildings.

8.2.4 Relocation and Resettlement Plan for the School

Xining Middle School, to be demolished and moved, covers an area of some 10 mu,

building area of nearly400㎡ , with over 50 staff members and over 700 students, of

which 500 are lodging students. Xining Middle School is subordinate to the Development Zone. The relocation and resettlement will be in full scale, funded wholly by the project. A new site will be selected to build a new school. The school will be relocated after the completion of new one. The new site is not fixed yet, but will be within Xining District.

8.3 Environmental Impact of Resettlement

8.3.1 Impact on living quality of relocated people

The resettlement houses in Guangde Resettlement Quarter will be built into urban residential community, with guaranteed quality, equipped with natural gas, complete drainage system, good human habitat environment and complete infrastructure.

112

Guangde Quarter has a better geographical location, shorter in distance to the city proper than that of the former Xining District, only half an hour’s drive, saving transportation cost and bringing conveniences to life. An antiquity-imitating street is built only 100 meters far from the Quarter; it is near Guangde Tourist Zone and can provide the resettled people employment opportunities.

The resettlement quarter is a comprehensive living quarter, into which some other resettled families of other construction projects have relocated and are satisfied with the resettlement.

In conclusion, the construction of this project will upgrade the resettled people’s residential and living standard, improve the sanitary conditions, help to better the local environment and achieve positive effects socially and economically.

8.3.2 Economic and Environmental impact of Resettled Enterprises

The planned industrial area for the resettled enterprises is the industrial enterprises concentration area projected by the Economic and Technical Development Zone in Suining Municipality; it is next to the exit of expressway and the site of railway station and long-distance bus station, eminently advantageous in transportation. Water, electricity, gas supply and other infrastructure are better equipped than that of the former Xining District. Dozens of large-sized leading enterprises like Qiquan Pharmaceutical Corp., Mingxian Pharmaceutical Corp., Kewang Group, Yihe Commerce and Industry, Dingxing Aluminum Corp., Jiangying Chemical Fiber have already invested in this district.

The project construction will not bring negative impact on production and business of the resettled enterprises. The sewage drainage will be controlled and disposed together when the enterprises resettle into the Industrial Zone, which will be beneficial to the environmental protection.

8.3.3 Impact of School’s Relocation and Resettlement

This project involves the relocation and resettlement of Xining Middle School, which will be a complete one, wholly funded by the project. A new school will be built within Xining District. The school will be relocated after the completion of the new one. The relocation will not interfere with the students’ normal learning, or bring any negative impact.

9.0 ECONOMIC BENEFIT AND LOSS ANALYSIS OF

ENVIRONMENTAL IMPACT

9.1 Social and Environmental Benefits of the Project

9.1.1 Suining Environmental Improvement Project, Sichuan Urban Development Project (SCDP), financed by the World Bank loan, is an significant measure of the World Bank to help China “eliminate poverty, improve environment”, and concrete embodiment of the great western development strategy of Chinese government.

With the Chinese government’s adoption the policy of reform and opening up to the outside world, in order to help China eliminate poverty, improve people’s human habitat environment and ecological environment, to support China’s economic development, the World Bank has provided loans for construction of urban infrastructure and protection of cultural heritage around China. In Sichuan province, Chengdu City, Luzhou City, Deyang City, Zigong City etc. benefit from it at different time, of which the First Phase of Sewage Treatment Project in Leshan and the Giant Buddha Protection Project are all direct beneficiaries. The completion of those projects has achieved direct and clear effects on the protection of local human habitat environment and natural environment as well as indelible contributions to the environment protection of China and the whole world. Suining Environmental Improvement Project is a multifunctional urban environmental project, including construction of urban communication infrastructure, flood prevention, sewage interception, afforestation etc., which conforms to the loan principles of the World Bank.

9.1.2 The construction of Suining Environmental Improvement Project will dramatically reduce the urban pollution of water, atmosphere, and noise and thoroughly improve transportation conditions in Suining City and its human habitat environment.

The construction of this project will pour new vigor and energy into Suining’s coordinated infrastructure construction and its urban function. It not only forms a network of communications, reduces traffic jam and disperses urban distribution, but also helps to form the metropolis structure from the current scale of Suining city proper. It is also of great significance for forming style and feature of a modern city, establishing nice city image, building ecological and garden city. Meanwhile it will help to achieve complete city function out of the urban areas along the Fujiang River. The construction and improvement of this project will integrate the eastern district of the river, Xining District and the old city proper, improve the communication network

114

conditions of each district, enhance the service function of urban communication, and make the city develop harmoniously as a whole.

9.1.3 Suining Environmental Improvement Project will greatly improve the investment environment, attract investment into Suining from inside and outside, realize the great-leap-forward development of economy and the sustainable development of Suining.

The prerequisites for a city’s development mainly include the maturity of its infrastructure and improvement of comprehensive environment. The construction of this project will greatly improve the human habitat and natural environment. The city proper of Suining will attract more investment from inside and outside. Economic development of the city proper will step into a new stage. With the economic development, the comprehensive environmental improvement in Suining will be enhanced; in this way it is favorable to form a good circle of economic development and environmental protection. This is the foundation for the economically sustainable and great-leap-forward development in Suining.

9.2 Economic Benefit Analysis of the Project

Urban environmental project is an integral part of urban infrastructure construction. Its economic benefits are often reflected in indirect economic benefits. Referring to economic benefit analysis of similar cities and similar projects, the construction of urban road infrastructure, dredge of river course, raise of standard for flood prevention, building intercepting trunk sewers etc. need investment of a large amount of capital. The investment for this project is estimated to be RMB 0.644 billion Yuan, of which 30 million US dollars from the World Bank loans. These loans will be repaid mainly by the appreciation in land value. According to relevant statistics (provided by Suining municipal government), the overall plan of Suining land use provides a total area of 3963.40 mu for the project, and still other land will be developed piece by piece. 40 million yuan can be obtained for land use annually, of which 23.22 million yuan will be used to pay the interests of the loans annually.

The old city proper (urban center) of Suining covers an area of 2.5 k㎡ , with an

average annual revenue of 40 million yuan. The constructed area of the project in the

district reaches 3.2 k ㎡ . Several large-sized pharmaceutical factories, cement

factories, Dingxing Aluminum Corp. and other high-tech corporations are located in this area, some of which have already began production, the rest of which also will begin production within this year. It is estimated that according to the revenue of the

115

old city proper that the established district will have annual revenue of 45 million yuan with supported people of only 700 and an annual expenditure of some 15 million yuan. Therefore there will be 30 million yuan at the established district’s disposal, part of which will be the fund to repay the principal and interests of the loans. The repayment is guaranteed.

9.3 Economic Benefit and Loss Analysis of Environmental Impact

9.3.1 Analysis of Environmental Loss

The land acquisition in the implementing of this project will transform the former situation of land use and the former ecological function and productivity.

Excavation is unavoidable in the implementing of the project, which will produce approximately 690 thousand m3 of deserted stone and earth. If handled improperly, the excavation will result in soil erosion due to the construction.

There may be environmental impact from traffic noise and flying dust in operation phase.

Generally speaking, the engineering workload of the project is not heavy and occupied land is not large. The environmental impact can be reduced to the minimum by way of strengthening the management and taking effective environment-protection and preventive measures.

9.3.2 Analysis of Environmental Benefit

The completion and operation of this project will improve regional transportation, the environment and urban scenery.

After the completion and operation of this project, the road surface will be solidified, the side slop will be improved meanwhile and the soil erosion of road surface and side slope will be avoided. The afforestation project will effectively reduce the intensity of the surface soil erosion, thereby reducing the local soil erosion.

The operation of the project will dramatically improve the regional transportation, thereby raising the speed of traffic flow. This will change the former situation of long-time wasting in driving and reduce the volume of waste gas emission as a whole, which will play a positive role in improving the local air environment.

The construction of sewage drainage lines of project will not only prevent the water

116

pollution of Fujiang River by new pollution sources in related areas, but also help to gather sewage to the sewage treatment plant for treatment, thereby preventing water pollution and protecting aquatic ecological environment.

After the completion of the project, the reasonably-designed and nice-looking urban roads are beneficial to the city’s ecological function. It will replace the disorderly distributed roads, thereby improving the city’s transportation, helping with the comprehensive improvement and promoting the upgrading of the urban scenery. Therefore this project has an obviously positive impact on the environment.

9.3.3 Economic Benefit and Loss Analysis of Environmental Impact

In compliance with the environmental protection laws and regulations, a series of measures have been taken in the construction of the project to maximally reduce the negative impact of the project. The investment in this respect is estimated to be approximately 8.25 million yuan, 1.3% of the total investment of the whole project.

The small amount of investment in environment-protection of this project will gain protection of ecological environment and satisfactory economic benefit in project operation. Its economic benefit, environmental benefit and social benefit greatly exceed the environmental loss. Therefore this project is feasible in respect of the environmental impact and economic benefit and loss, if the environment protection work is conscientiously done and the investment in environment protection reaches in time.

10.0 PUBLIC CONSULTATION 10.1 Objectives and Effects

Any construction project must have positive or negative impacts on the surrounding physical and socioeconomic environments from its planning, design, construction, and completion till its operation. And thus it is to have an influence on the life, work, study, rest and recreation of the surrounding residents directly and indirectly. They are benefited or suffered from the project directly or indirectly. Their participation may remedy the possible omission and carelessness in the EIA. Their opinions can make the planning and design of the project more perfect and reasonable, the measures of environmental protection more practical, thus making the project more benefits on environment, society and economy.

Through the public participation, let more people know the significance of the project and the environmental problems caused by the project so as to obtain the support and understanding of the public. It is favorable to carry out the construction. In addition, the public participation has an active promoting effect on improving the environmental awareness of the public and participating in the work of environmental protection consciously.

10.2 Methodology and Principles

The public participation of the project has two steps:

Step One: First issue questionnaire sheets, and then analyze the response of those sheets. The statistical results and analysis will be put into the Draft EIA Report.

Step Two: In the compilation process of Draft EIA Report, the project owner sponsored meetings of monks of Guangde Temple and representatives of local residents to hear their opinions or responses in terms of the environmental impact of the project. And Disclose the Draft EIA Report which will be shown in the lobby of Suining Construction Bureau, and issue the relevant information in the newspaper of Suining Daily as well as the radio station. Meanwhile, hot-line telephone number will be also issued. So local people can get to know the project, and put forward some suggestions.

10.2.1 Survey by Questionnaires

118

Representativeness (property of representation) combined with randomness is considered as the principle of the survey by public participation questionnaires. Representativeness means that the people who are surveyed should come from various circles of the society. The proportion of the people must be proper. Randomness means that the selection of the people who are investigated should have the statistic characteristics of random sampling. Among the people whose types of sample are identified, take out the people for the survey randomly. The selection of the people who are investigated should be justly without personal feelings of the surveys or investigators.

Take the problems which are closely related with the public as the content of the survey. In order to save the time and count up easily, select the symbol " √ " for answering most of the survey. The questionnaire sheets are just like Table 10-1.

In term of environmental management, the following contents are of importance.

1. Institutional Arrangement

Besides the existing environmental protection and monitoring institutions, the project owner should set its special department of environmental protection. The department comprises of management division and monitoring division (laboratory) with 3 ~ 4 staff. One of the top managers of project owner should be in charge of the environmental protection work. He/She should create necessary working conditions and related working disciplines, and he/she has power to carry out his/her functions. The institution and its working capacity should be checked and accepted together with the project at the end of construction by relevant authorities.
