1 Preface

The Environmental Improvement Project in Yibin City, Sichuan Province is also called Binjiang ring road project for short. It consists of road project, bridge and culvert project, protective project, landscape project and drainage project. The proposed road project is an import part of the urban road network planned by the municipal government, and involves two parts, namely Line A and Line B. Line A is laid along the left banks of the and the River, extending from east to west. It starts from the Min River North Bridge and ends at Tianyuan Co., Ltd., with a total length of 6688.51 meters. Line B starts from the Cultural Square of Nan’an and ends at the No. 4 Water Plant, following Nan’an (south bank) of the , with a total length of 3521.21 meters. The main functions of the project are transportation and relaxation. The total investment is RMB 574.06 million, of which USD 28.5 million is financed by the World Bank. According to the urban master plan of Yibin, the city will be composed of multi-districts with diverse function and characteristics. The proposed road of Line A is the only way connecting Jiucheng, Jiuzhou with Baisha. The proposed road of Line B connects West of Nan’an, East district of Nan’an, Zhaozhou and Tianbai, which are important districts of the city. The proposed road is the significant urban road connecting various districts and has great potential for traffic volume increases. The proposed project will facilitate the swift connection among the districts and promote the smooth and ordered flow of passengers, freights and automobiles. It can activate the adjustment of urban structure through the improved urban road networks, providing necessary and basic guarantee for the expansion of urban development space and the improvement of the urban functions as well. Based on the relevant environmental protection laws, regulations and standards of the People's Republic of China (PRC) , and the stipulations in the Guideline of Environmental Assessment by the World Bank, the proposed project is classified as Category A, and the environmental impact assessment should be carried out. Therefore, Hydropower Investigation Design & Research Institute (CHIDI) of China Hydropower Engineering Consultant Group Corporation (CHECC) was commissioned to undertake the EIA of the proposed project by Yibin Investment Group Co., Ltd (YIG). After accepting the commission, an EIA team was established coming from engineers majored on environmental protection, road and bridge design, and water and soil conservation and so on. Based on the analysis on the project design documents, the EIA team carried on investigation along the proposed roads for several times. The basic information of the construction area, the project construction document and monitoring data were collected.

1 1 Overview

1.1 Origin of the assessment

Yibin is an important city in the south of Sichuan Province. It is also a famous national historical and cultural city, central city in the up reaches of the Yangtze River, comprehensive transportation hub in the border areas of Sichuan, and Provinces. In the recent years, Yibin has become the supporting city for developing hydropower of the Jinsha River, the Panxi-Liupanshui region rich in resources, and an important ecological green screen on the upper Yangtze River. Yibin is famous for the name of ‘The First City along Ten-Thousand-Mile Yangtze River’, for the Jinsha River and the Min River converges into Yangtze River here. Taking the drink, food, chemical fiber, chemistry, pharmacy, paper making and energy as its support industry, and wine as its characteristics, Yibin is a city of great development potential and investment value. Separated by rivers and mountains, the urban construction area in Yibin is disintegrated and scattered, and is characterized by typical district structure. The city is developing quickly in recent years, and the land demand for city construction is expanding continuously. However, limited by the especial landform, the available land is short. Furthermore, the municipal infrastructure is so backward that the city development is unable to obtain a breakthrough in a short term. Because of the historical reason, the old urban district is intensely populated, and is very short of construction land. Nan’an District is presenting a fast expanding tendency owing to the comparatively better environment and better infrastructure. Zhaochang, Caiba, Baisha, Lizhuang and Luolong, etc. are also concentrated areas for the construction used land. Line A of the proposed road project locates in Baisha District while Line B locates in the Nan’an and Zhaochang District. The project construction is to provide necessary guarantee for the expansion of the above districts and to release the tense situation of the urban land. At the same time, the proposed roads are important components of the road networks according to Yibin Urban Master Plan. The construction of the proposed project will facilitate the swift connection among the districts and to achieve the ordered and smooth flow of passengers, freights and automobiles. It can activate the urban structure adjustment and improve the urban functions as well.

1.2 Background of the project 1.2.1 City plan of Yibin 1.2.1.1 Social and economic development plan According to ‘the Tenth Five-Year Plan Summary of Yibin National Economy and Social

1 Development’, the strategic station of Yibin City in the Development of is: build Yibin into a first-level central city along the upstream of the Yangtze River, the communication hub on the border areas of Sichuan, Yunnan and Guizhou Provinces, the supporting city for developing hydropower of the Jinsha River, the important component part of the ecological protection barrier along the upstream of the Yangtze River. 1.2.1.2 Urban construction plan Separated by rivers and mountains, the present urban construction area is divided into 7 districts along the Yangtze River, the Min River and the Jinsha River. The districts are Jiucheng, Jiuzhou, Nan’an, Baisha, Caiba, Yanpingba and Tianbai. Jiucheng and Tianbai are the old urban districts, where is intensely populated, and is very short of land. The environment there is not so good either. People should be transferred outward. The built in Yibin is 33 km2, 73.7 m2 construction lands per capita in 2004. The population density in the Jiucheng is especially high to 60 thousand persons per kilometers. According to ‘Yibin Urban Master Plan (1997) ’, the population of Yibin is estimated above 1 million in the future, and the construction land demand is above 100 km2. Regard to the layout of urban construction land, four main development axes are to be formed with Jiucheng as the center, and developing along the Jinsha River, the Min River, the Yangtze River, expressways and railways. The four development axes are Tianbai-Zhongba- Jiucheng along the Jinsha River; Jiucheng-Nan’an-Baisha-Yanpingba along the Yangtze River; Jiuzhou-Jiucheng-Tianbai along the Nei-Kun Railway; Caiba-Jiuzhou-Jiucheng along the Min River. Thus several districts with different functions and characteristics will be formed in the future. The basic situation of every district is as follows: Jiucheng District: The planned area is 3.65km2. The population will be controlled to 100,000. It will not only be a trade, culture, and information center, but also an area mainly for historical cultural protection. Zhongba District: The planned area is 1.67km2. The planned population is 25,000. It is the railway transportation center of whole city. Caiba District: The planned area is 15.15 km2 and the planned population is 110,000. It is a comprihensive area aiming at living, vacation and entertainment, with high-tech research projects to be developed properly. Tianbai District: The planned area is 12.21 km2 and the planned population is 147,000. It is an energy industrial district, hydropower base and railway transport hub. East District of Nan’an: an urban district concentrated with urban administration, business, finance, service, culture, and entertainment, with the planned area of 7.3 km2 and the planned population of 105,000. West district of Nan’an: An urban district concentrated with education, science research, high-tech industry and residential buildings, with the planned area of 8.72 km2 and the

2 planned population of 85,000. Zhaochang District: The reserved logistics base for Panxi-Liupanshui exploitation, with the planned area of 15km2 and the planned population of 100,000. Yanpingba District: A heavy industrial area, with the planned area of 1.58km2 and the planned population of 9,000. Lizhuang District: The famous national historical culture town and a comprehensive district mainly for industry, tourism and logistics, with the planned area of 119.7km2 and the planned population of 207,000. Jiuzhou Districts: A comprehensive district with functions of production, logistics, life, administration, education, business etc and the gateway to go in and out of Yibin, with the planned area of 16.06 km2, the planned population of 120,000. Baisha Districts: .A comprehensive district mainly for the heavy and light industries and the corresponding logistics and resident, with the planned area of 12.8 km2 and the planned population of 121,000. Yibin urban master plan is shown in Figure 2. The development focus of Yibin is to explore to the west and east and to form a main zone. Westward expansion will include the 2nd Phase construction of West District of Nan’an, Zhongba, Tianchi and the starting construction of Zhaochang; Eastward expansion will include the industrial developments of three districts—Baisha, Lizhuang and Yanpingba. The Construction of the proposed project is import because it’s the link of the above mentioned districts, and the two part of Line A and Line B is the key of the whole ring road project. 1.2.1.3 Transportation plan The Yibin transportation network is composed of road, railway, ship and airplane, which has formed a multi-level network due to the fast development of the city since performing the reform and open policy. At present, Yibin has formed a highway network with the urban city as the center, two national ways (G240, G213) and four provincial ways (S206, S307, S308 and S309) as the framework and county and rural level roads as links. According to Yibin Urban Master Plan, the urban traffic development strategies is to set up the fast public transportation system and throughway system to cultivate and support the district-style urban structure of Yibin. The throughway system is to accelerate the connection between districts, induct the passing through traffic, and ensure that there are two trunk roads between every two districts. The throughway system presents the ‘one ring and two sub-ring’ structure. The proposed project is an important part of the ‘one ring’ road, which plays an important role in switching the internal and external transportation of Yibin.

3 1.2.2 Necessities of the project construction 1.2.2.1 To adapt to the Western Development Strategy and to promote the local social and economic development The goal for realizing the overlying development in the first 10 years of the 21st century has been put forward by Sichuan province, taking the urban construction and development as the focus of the national economic and social development. The project grasps the opportunity to carry out the governmental strategy, improve the urban infrastructure and the living standard of the local people. Thus it can facilitate the general progress of the local national economy and social affairs. 1.2.2.2 To improve and optimize the urban spatial structure and to facilitate implementation of overall urban layout The city structure of Yibin is the typical district-structure with the conflux of three rivers and the confront facing of three mountain. At present, Yibin is very short of construction land, and the expansion of the urban space is in urgent need. The key to expand the urban space is to strengthen the connection between the old and new urban districts. The proposed project will provide conditions for the exploration of new urban district. Line A extends from the Min River North Bridge to Tianyuan Co. Ltd. It is the only road connecting Jiucheng, Jiuzhou and Baisha. The Jiuzhou district is a comprehensive district with the production, trade, community, administration and culture as its main industry. Among them, the material circulation of Wuliangye group Co. Ltd. is the most. Baisha district is a comprehensive district mainly with the first and second industry and relevant material circulation. The Jiucheng district is the central district of Yibin. Thus, the connection between the three districts is very important, and there exists great potentiality for traffic volume in Line A. Line B extends from the Cultural Square of Nan’an to the No 4 Water Plant, passing four important urban districts including East District of Nan’an, West District of Nan’an, Zhaochang and Tianbai. At present, the construction of East District of Nan’an and Tianbai has been finished; The West District of Nan’an is under construction. Line B is also an important connection among the urban districts, and the potentiality of the traffic volume is great in future. 1.2.2.3 To accelerate the urbanization progress and to play the function of the regional center city The implementation of the project will further improve the urban environment, driving the construction of the districts including the Baisha Industrial Park, West District of Nan’an, Dadipo, Zhaochang and so forth. It can accelerate the urbanization progress, improve the urbanization level, expand the urban scale actively and efficiently, strengthen the position as the regional center city, and drive the overall economic development in the southern

4 district of Sichuan Province. Finally it can consolidate Yibin’s status as the important city in Southern Sichuan, and to make great contribution to the economic development of Sichuan. 1.2.2.4 To improve the urban transportation network, strengthen the urban serving function and to improve the urban environment The proposed project is the important hinge for the switching of internal and external transportation of Yibin City, which is closely connected to other external transportation networks such as the Yibin-Nanxi Road and so forth. The reasonable and scientific layout of the transportation network among the districts hasn’t been formed yet, and the existing roads between districts are mostly low-grade roads far from satisfying the need of the increasing transportation. The construction of the proposed project will improve the transportation conditions between districts. The proposed project will also play an active role in furnishing the corresponding municipal supporting facilities, strengthening the urban serving function and expanding the urban scale. According to ‘Yibin Urban Master Plan’ and the relating detailed plans, the domestic sewage from Jiuzhou, Jiucheng and Zhongba is collected and sent to Yangwan Waste Water treatment Plant (WWTP) located at the downstream of Jiuzhou. The sewage from the new part of Nan’an and Dadipo is sent to Nan’an WWTP. The drainage work along Line A and B in the proposed project is an important part of the main sewage pipes of the WWTP mentioned above. Its construction can improve the corresponding municipal facility in further. Moreover, the proposed project is located at the important characteristic area (called Binjiang) of Yibin. The proposed project on the riverside will provide the residents with a sound entertainment and leisure space and sightseeing along rivers. On the other hand, as a result of the smoother traffic and faster vehicle speed, the total exhaust emissions may be reduced and cause positive impact on the ambient air quality.

1.6.2 Assessment classification The determination of the EIA Grades is based on the influencing degree and scope. According to the approved outline of EIA, the assessment grades details of each environmental element are listed as followed. (1) Surface water environment The sewage is mainly derived from the construction activities and daily life of workers. The main pollutant of the construction sewage is SS, while the main pollutants of the domestic sewage are BOD and CODcr. The amount of sewage produced during the construction is less than 1000t/d and its ingredient is simple. Besides, the received water areas are big rivers, with Class III surface water function. According to the Technical Guidelines for EIA - Surface Water Environment (HJ/T 2.3-93) , the assessment classification of surface water environment is determined as the third grade. (2) Ambient air The construction dust and the contaminant from automobile exhaust are the main air pollution sources. The influence region is limited within a certain area on both roadsides. The main contaminants are TSP and NOx with lower intensity. According to ‘Technical Guidelines for Environmental Impact Assessment - Air Environmental’ (HJ/T 2.2-93) , the assessment classification of ambient air is determined as the third grade. (3) Acoustic environment

12 The construction area belongs to the acoustic functional zone of Class and Class , according to ‘Noise Standard in City Region’. The noise level may have an obvious increase after the project is completed, and a lot of population is affected. According to ‘Technical Guidelines for Environmental Impact Assessment-Acoustic Environmental’ (HJ/T 2.4-1995), the assessment classification of acoustic environment is determined as the second grade. (4) Ecological environment The affected area of ecological environment is estimated to be smaller than 20 km2, with reduction of biodiversity less than 50%. This won’t cause perdition of species. According to ‘Technical Guidelines for Environmental Impact Assessment Non-pollution Ecological Influence (HJ/T 19-1997) , the assessment classification of ecological environment is determined as the third grade. 1.6.3 Assessment scope The assessment scopes of environmental elements were roughly analyzed on the basis of natural and social environmental characteristics along the line, according to ‘Technical Guidelines for Environmental Impact Assessment Non-Polluted Ecological Impact’ HJ/T 19-1997 and ‘Specifications for Environmental impact Assessment of Highway’.

2.5 Main part project

The Environmental Improvement Project in Yibin City is also called Binjiang ring road project for short. It consists of road project, bridge and culvert project, protective project, landscape project and drainage project. 2.5.1 Road project (1) Line A Most of Line A is the reconstruction and extension of the existing road. The total length of the road is 6688.51m and the width of the road is between 18m and 21m. It is designed as bi-directional four lanes urban sub-trunk road from the starting to Caiyuantuo Bridge (A0+000~A5+160) , and as two lanes from the Caiyuantuo Bridge to the end (A5+160~A6+688.51) . The designed speed is 40 km/h. The maximum longitudinal slope is 5.62% and the minimum longitudinal slope is 0.3%. The transversal slope is 1.5%. The asphalt concrete road surface is adopted. (2) Line B Line B is a new road to be built. The total length of the road is 3,521.21m and the width is between 20 and 24m. It is designed into bi-directional two lane road according to the standard for urban sub-trunk line and the designed speed is 40 km/h. The maximum longitudinal slope is 1.0% and the minimum longitudinal slope is 0.3%. The road arch transversal slope is 1.5%. The asphalt concrete road surface is adopted. (3) Road crossing The traveling speed at the crossings on both Line A and Line B is designed to be 20~ 25 km/h. The pavement structure will adopt the same standard as the main lane. There is 11 level crossings and one flyover crossing on Line A, 6 level crossings on Line B. 2.5.2 Protective project The protective works in the proposed project are the retaining walls on Line A and Line B. On Line A, the retaining wall is to set on the outer side of the section A0+780~3+690 and both sides of the road section after A4+000 where the buildings are dense. On Line B, one part of retaining wall is arranged on the north of the section between B0+000~3+521.21. There is one bridge set on B2+340~2+465 and the retaining wall is broken at the bridge abutment. The other part of the retaining wall is located at the south of the section after B1+600, where are the excavated slope toe and partial filled area. The type of the grouted block stone retaining wall is adopted. Guardrail is to be set at the outside of the footway on all sections where the height of

20 filling is higher than 3m. The guardrail length of Line A is 2,910m and that of Line B is 3,521m. 2.5.3 Bridge and culvert (1) Bridge works The project is constructed following the Jinsha River, the Min River and the Yangtze River. No cross-river bridges are designed in the project. But bridges are designed when crossing big natural gulches. There are four bridges on Line A and one on Line B. 25m packaged type ‘T’ beam structure and prestressed concrete continuous beam bridge structure are adopted for the topside structure of the bridges. The technical specifications of bridge works are shown in Table 2-3

(2) Culvert project Culverts are arranged where there are small natural gulches and where the existing rain water outlets can’t connect with the designed rain water pipeline. The culvert size is decided according to the collecting area. The structure of the culvert will adopt reinforced concrete slab. There are 11 culverts on Line A and 9 on Line B. 2.5.4 Drainage project The road drainage works of Line A and Line B is independent from each other, with the principle that the rainwater and sewage be separated. According to the detailed planning on drainage control of the Districts in Yibin, the rainwater collector of the project is constructed down the road grade and the outlets is properly added to make the rainwater drained into the river nearby. The sewage pipe network along Line A is designed according to the planned sewage flow direction and divided into three parts. The first part is the trunk sewage pipe in Jiuzhou along Section A1 (A0+000~A0+400) , transporting the sewage from Zhongba, Jiucheng

21 and Jiuzhou areas into Yangwan WWTP. There is no sewage pipes on the second part of Section A2 (A0+400~A3+820) , for there is no sewage in the colleting areas where borders Jiuzhou and Baisha district. The third part is the trunk sewage pipe in Baisha district along Section A3 (A3+820~A6+668.51) , transporting the sewage in the collection area into the planned Baisha WWTP. The sewage pipes along Section A3 are drained in two opposite directions taking the Yibin Power Generation plant as the drainage divide. The sewage upstream the plant flows to the Baisha WWTP in the direction of gravity current. The sewage downstream the plant will flow by gravity into Baishawan first and then lifted to the trunk sewers behind the plant by the sewage pumping station at Baishawan. After that, the sewage flow to the WWTP by gravity. Another part of sewage in the area of Changjiang Paper Industry Co. Ltd. is also lifted to the trunk sewers by pumping station. All the sewage pumping stations are not included in the SUDP project, only joint be preserved. The sewage pipes of Line B pass through east district of Nan’an, Dadipo and Zhaochang districts, with most of them lying in Dadipo. There is already a sewage pumping station near B0+115, so the sewage along Line B will be transported to the pumping station first and then lifted to Nan’an WWTP. The drainage plan is shown in Figure 4. 2.5.5 Landscape project The landscape will combine the characteristics of the natural environment in Yibin City and reveal the local cultural style and features. The landscape design will be a comfortable place of relaxing and sightseeing for the citizens. There are four landscape spot on Line A. Besides, the greening along the road is realized with roadside trees. There is enough space in eastern sub-section of Line B (from the Cultural square of Nan’an to Yibin Tea Co., Ltd. ) , so both sides of the road is provided with a 3-meter-wide footway and the rest space is planed as green belt planting shrubs and trees. One side of the Road faces the river where the space open and the environment is beautiful, so handrail and seats on the footway are provided on the bank side, providing a good place for the citizens to rest and relaxing. The 2-meter-wide green belt is set between the driveway and the footway in western sub-section of Section B (from Yibin Tea Co., Ltd. to No. 4 Water Plant) , in order to separate and organize the traffic, guide the visual line and increase driving safety. The plan of landscape works is shown in Figure 5.

22 2.6 Construction organization 2.6.1 Construction transportation and the supply of water and electricity 2.6.1.1 Construction transportation The external transportation condition of Line A is very good. But if the construction can not be closed on the whole road, construction must be arranged section by section or breath by breath. Line B is a new road to be built on the relatively complex land. Thus the external transportation condition is not very good. If the demolition of the residential buildings of the Construction Committee and tea factory falls behind, the existing road under NeiKun railway will be the reasonable way to the construction site, and construction will be done from middle to the two ends. 2.6.1.2 Water supply during construction phase Water storage pool for construction use will be connected with the tap water pipe, and then supply water to each construction site with pumps. The capacity of water storage pool is above 20m3. During water shortage times, water will be transported by water truck and preserved in the storage pool. 2.6.1.3 Electricity supply The electricity for construction use is offered by the municipal electricity supply system through the 600kVA transformer. The electric transmission route should be controlled within 800m. Meanwhile, five 250kVA generators are prepared to make sure the construction not affected by the power cut. 2.6.2 The amount of earth works and the layout of waste disposal fields The earth and stone works mainly come from the road and the protective works, the quantity is shown in Table 2-5.

23 Total 40.2 16.32 3.86 45.88

The total quantity of construction waste is 548,000m3. One waste disposal field is designed locating on the bottomland near A2+640 with the capacity of 15,000 m3 and the area of land occupation 1580m2. The rest construction waste is used to fill the inner land of the left embankments of the Jinsha River. It is completely capable to contain the construction waste of the proposed project and is convenient to transport through several cross-river bridges. 2.6.3 Borrow pits The sand and concrete aggregate needed in the proposed project will be bought, and the stone material will be extracted from the excavation of the proposed project. 402,000m3 earth work need to borrow in the proposed project and one borrow pit is set on the roadside near the section A3+000. The borrow pit is on the side far away from the river and does not belong to the riverside ones. 2.6.4 Construction plan The concrete needed is brought from providers and carried by the concrete mixing truck. The pouring concrete for bridge project is sent by concrete pump. One asphalt and concrete mixer is arranged at A0+480, where is a debris field now. There are few building surround the site and the nearest building is 200m away. The capacity of the mixer is 300T. The asphalt concrete mixture is preserved in heat isolated material container and be carried to construction site by 16t auto-unloading truck. Burlap bags are needed to keep the container warm and rain cover is also need to prevent rainwater and dusts. There is no mixer on Line B and the asphalt and concrete materials needed in the subproject will be taken from Line A directly. Two stabilized gravel aggregate concrete mixer are located at A0+480 and B2+360 respectively. 2.6.5 Construction progress and labor number The construction will last 36 months, and is scheduled to start in Jan., 2006 and complete in Dec., 2008. The total labor is 943,785 man days, with 600 persons per day in average and 900 persons per day in peak period. The peak period is estimated to last from June, 2006 to June, 2008. 2.6.6 Construction method 2.6.6.1 Roadbed project The quantity of excavation in the road project is smaller than fill and earthwork redistribution plan is carried out during construction. Considering the efficiency, the

24 longitudinal transfer distance generally is less than 1km. The rest earthwork will be transported to the designed waste disposal field. Constructs the rebuilt road or ditch firstly and then construct the main line in the same section. For the excavation of soft or medium soft stonework, use the soil loosing machine of the high efficiency bulldozer to loose the stone first, dig and load using grab and loader, and then transport with the auto-unload truck. Fort the construction of section with hard or sub- hard stonework, it is proposed to adopt stone explosion scheme. Reserve the smooth surface explosion layer first. After the stonework excavation of the main part finished, blast with the combination of the presplitting blasting and the smooth blasting near the slope, and adopts shallow-hole controlled blasting method near the bed surface and lateral groove. The method of mechanical filling and compacting layer by layer is adopted in the embankment filling. Before the filling construction, the embankment basement will be treated firstly, cleaning all the unsuitable materials and mucks, and doing the local basement backfill and compacting work well. 2.6.6.2 Road surface project The concrete stable gravel layer is 25cm thick, paving at one time. Construction should not be interrupted in normal construction days. Each 100m is taken as a unit of forming and roller compacting, constructing unit by unit. The paving machine is used to pave. The prime coat and tack coat asphalt is sprayed mainly by asphalt sprayer car and brushed artificially at local places where sprayer cannot reach. After the emulsified asphalt infiltrated and the moisture evaporated fully, pave the asphalt surface layer as soon as possible. 2.6.6.3 Bridge project

The basic construction procedure is: Staking out in the survey foundation construction substructure construction superstructure construction deck pavement and auxiliary facility construction . Open excavation method is adopted at the foundation pit. The upper soft layer part is excavated artificially combing with the back-hoe excavator. The stone masonry of the abutment foundation is constructed artificially. The mortar is mixed on site with 0.35m3 mortar mixer. Bored pile is used. The bridge column uses finalized the steel die. Set up the mold one time, and lift concrete continuously for placing and shaping. Centralized precast and track transport method are adopted for ‘T’ beam. One precast field is set, including steel bar workshop, template workshop, cement storeroom, equipment storehouse, temporary office, concrete transport vehicle, autohoist and so on.

25 2.6.6.4 Culvert project The culvert head slab is precasted in the precast field by construction team. After the slab is transported to the construction site, the crane is used to install the slab. The cast-in-place construction method is used in the culvert foundation construction. The concrete mixing is centralized and the mixed concrete is transported by concrete truck. All the grouted mortar is mixed by mortar mixer. The open-excavation foundation is excavated using excavator, cooperating with manual work. The water collecting well is adopted to collect water, and the pump is used to drain when there is water in the foundation pit. 2.6.6.5 Protective project The Protective project mainly includes slope protection, surface protection wall, and retaining wall and so on. During the retaining wall construction, protection measures for each section must be taken at once as soon as the excavation finished, in order to guarantee the side slope of the roadbed is stable and not corroded by rain. The side slope protection will be completed in one month after the roadbed soil and stone work finished. Before the construction of the slope protection, the slope surface must be made to meet the requirement. Shallowly dig the frame-style base slot, tamp manually, build rubble to protect slope, cleaning the construction waste at the same time. Before constructing the surface protection wall, eliminates the loose stone and earth on the side slope, make the fresh surface revealing. Set the expansion joint and settlement joint, construct section by section. After the foundation pit of the retaining wall was excavated, the sounding penetration test should be carried out. If the bearing capacity cannot satisfy the design demand, it should be reported immediately, and be processed such as spread or consolidated foundation. When the masonry and building of the retaining wall is carried on, backfill and ramming should be done in time, avoids water infiltrating. The concrete intensity must be higher than 70% when backfill. 2.6.6.6 Drainage project There are many drainage types, such as side ditch, drainage ditch, intercepting ditch, chute and so on. The intercepting ditch of the excavated section and the lower retaining wall of the filling section should be constructed at first, in order to help the excavating and filling carried out smoothly, and form the flow production. The roadbed side ditch is located on the top retaining wall. The drainage ditch and the chute should be finished before the rainy season, in order to help draining water. Water- closed test should be done for all the pipes. The drainage project construction should not be arranged in rainy season as far as possible. The layout of the underground pipe network should be known before the excavation of ditches.

26 2.7 Project analysis 2.7.1 Accordance analysis of the project 2.7.1.1 Accordance with the ‘Urban Master Plan of Yibin city’ According to the ‘Urban Master Plan of Yibin city’, the strategy of Yibin is aimed at a famous national historic and cultural city; transportation hub and trade center of Sichuan, Yunnan and Guizhou Province of the upper Yangtze River; a regional central city with energy, food and chemistry as its leading industry and the spirits as its characteristics. The city will be composed of multi-districts with diverse function and characteristics. The Line A of the proposed project connects Jiucheng, Jiuzhou and Baisha, while the Line B connects the West district of Nan’an, East district of Nan’an, Zhaozhou and Tianbai. The proposed project is a part of the road network contained in the city plan. The proposed project will facilitate the swift connection among the districts and promote the smooth and ordered flow of passengers, freights and automobiles. It can activate the adjustment of urban structure through the improved urban road networks, providing necessary basic guarantee for the expansion of urban space and the improvement of the urban functions as well. At the same time, the landscape is designed taking the historical culture and the Yangtze River as its main topics. It will be an ideal place for the citizens to live, relax, sightsee and tour. It also can be an important factor for the improvement of the investment environment. 2.7.1.2 Accordance with the ‘Road Network Planning of Yibin city’ During the tenth five-year plan, ‘one ring, three bridges, three road’ project and Binjiang Road project in Jiucheng, Zhongba and East district of Nan’an will try to finished, in order to mitigate and improve the traffic congestion situation. Among the preceding mentioned project, ‘one ring’ indicates the Binjiang ring road connecting the Jiuzhou, Baisha, East and West district of Nan’an and Zhongba. It starts from the Yibin North Station of the Nei- Yi expressway, passes through Jiuzhou and the Min River Bridge, turns west and follow the Min River and the Yangtze river to Baisha, crosses the Yangtze River bridge at Caiyuantuo, passes through East and West district of Nan’an, turns north to stride the Jinsha River Bridge at Zhongba, and at last ends at Pianchuangzi overpass of Nei-Yi expressway. The proposed project is just an important part of the ‘one ring’ road. It is also the important hinge for the internal and external transportation of Yibin City, which is closely connected to the external transportation road such as the Yibin-Nanxi Road. It is obvious that the proposed project is accordance with the traffic network plan of Yibin. 2.7.1.3 Accordance with the drainage plan of Yibin city The rainwater and sewage is separated in most of the urban city areas, except the Jiucheng

27 District, some part of Jiuzhou District and most part of the Baixi District. There are three waste water treatment plants (WWTP) in Yibin, which are Yangwan, Baisha and Nan’an. The detailed information about the WWTP is shown in Chapter 4. The drainage system of the proposed project is designed as separate rainwater pipes and sewage pipes. The sewage pipes in the proposed project are components of the sewer system of the WWTP above. Its construction will improve the corresponding municipal infrastructure, strengthening the city’s service function. It is coordinate with the detailed drainage plan of the relating districts. 2.7.2 Rationality analysis of the project 2.7.2.1 Rationality of Route Selection Most of Line A belongs to reconstruction and extension project, small part of Line A and all of the Line B belongs to new road. All the proposed roads are roads planned in the ‘Urban Master Plan of Yibin City’ and ‘Road Network Plan of Yibin City. The land utilization is in accordance with the Urban Master Plan. At the same time, the altitude of the proposed roads are higher than the flood lever with 5% probability, and is out of the boundary of the national natural reserve of rare and special fish in the upper reaches of the Yangtze River, so the routes are compliance with the reserve’s master plan and its managing demand. According to the on site investigation, the road route avoid the famous scenery, natural conservation areas, the important human landscapes and eco-sensitive spots, minimized vegetation disturbance and building demolition. From the view of environmental protection and water and soil conservation, the layout of the road is reasonable. Detailed alternatives of the route layout see Chapter 3. 2.7.2.2 Rationality of the construction field layout (1) Local residential houses are rented to be builders’ temporary living area. It can make the utmost use of the existing urban living facilities, avoid the rebuilding and reduce the area of temporary land occupation. (2) An asphalt mixing station and a stabilized gravel mixing station are assigned at A0+480, where is a debris field now. None residential building is located in the range of 200m leeward. There is also a stabilized gravel station at B2+360, where is flat between two massifs and far away from the river, only 1~2 households located 200m away. All the above sites avoid the crowded area. It is reasonable from environmental protection angle. However, the transportation route for construction materials should be appropriately planed further at the next stage, and necessary measures should be taken to decrease adverse impact to nearby environment. (3) According to the topography in the construction area, there is little land that can be used to dump construction waste. About 548,000 m3 earthwork from the proposed project 28 is discarded. Most of them will be used to fill the inner land of the left embankments of the Jinsha River opposite to Line B. The capacity meets the project demand and the transportation condition is convenient. The filling work will be put into related project and the water and soil conservation work will not be included in the proposed project. In addition, a waste disposal field is designed on the bottomland near A2+640. It can contain a part of earthwork from Line A, about 15,000 m3. As the waste disposal field is close to the river, some protect measures should be taken to avoid soil erosion, such as building retaining wall, setting drainage ditch on the wall, greening on slope. In summary, the capacity of the assigned waste fields can meet the demand of the proposed project. The backfill of the discarded earth can minimize the soil erosion, and it is helpful for water and soil conservation. The transportation of the construction waste will make use of the cross-river bridges, so it is convenient in transportation, but dust control measure should be taken at the same time. 2.7.3 Analysis for main impact sources 2.7.3.1 Main impact sources during construction phase (1) Noise In the project, construction noises mainly come from exacavation, transportation, concrete mixing and the building demolition. The noise value is 79~90 dB (A) , according to the monitoring report of analogy project. (2) Air pollution During the construction phase, main air contaminants is asphalt smoke during asphalt mixing and transportation, and flying dust caused by building demolition, materials transportation or other activities. (3) Surface water pollution The pollution to the water environment mostly comes from the construction of bridge piers and embankment, and the living sewage. The main pollutants of the bridge and retaining wall construction is SS, while the main pollutants of the domestic sewage are BOD and CODcr, with the discharge of 103m3/d at the peak construction period. (4) Ecological environment Soil erosion may occur due to the damage of the vegetation during construction period. The construction waste may cause soil erosion without reasonable disposal. (5) Social environment As the project roads is closed or partially closed during the construction period, the transportation, normal production and living of the residents and enterprises along the line will be affected.

29 The resettlement will affect the life of the residents and the environment of the new resettled areas in a certain extent. 2.7.3.2 Main impact sources during operation phase (1) Noise Most of the acoustic environmental impacts are caused by the traffic noise, which will affect the life of the residents along the line. The noise source intensity is closely related to the truck type and the speed of motor vehicles. (2) Air pollution In operation phase, the main contaminants are NOx, produced by the discharge of the auto tail-gas, and TSP. (3) Surface water pollution The water contamination source mainly comes from the road surface runoff. The main pollutants are oil, SS. In addition, the vehicles carrying dangerous materials will probably have leakage accident, which will cause adverse effect on the water. (4) Solid waste The rubbish generated by drivers, passengers, pedestrians or residents along the line is managed by urban management bureau, collected and sent to municipal landfills for final disposal in time. The waste mainly comes from traffic accident and road maintenance. (5) Social environment After the project completed, the external transportation condition will be improved, promoting the city’s development and the living condition of the residents. If the resettlement is arranged well, it will be helpful for the development of Yibin and the improvement for the immigrant’s living condition. The identification and screening of environmental impacts of the project is presented in Table 2-7.

3.1 Comparison of with or without the project

(1) Scheme one: Yibin Binjiang Ring Road Project. (2) Scheme two: no project scheme. Environmental impacts on with or without the project construction are showed in Table 3- 1.

Table 3-1 shows that there is some adverse impacts due to the proposed project during construction and operation phase. But the impacts are limited and temporary, which can be removed or mitigated by taking various mitigation measures. In a long run, construction of the proposed project can not only improve the city traffic conditions and eco-environment, beauty the city, but also raise living standards of the people, promote sustainable development of Yibin city, which is in accordance with local people’s requests.

3.2 Road alternatives

All the proposed roads are components of the planed projects listed in the ‘Urban Master Plan of Yibin City’ and ‘Road Network Planning of Yibin City’. The planned roads in the

32 city plan are optimized roads and have been selected according to the requirements of economic development and traffic increases. The environmental improvement demand is also considered during plan drawing process. The land utilization along the road is also accordant with the city’s master plan. So optimization is made only for local sections during the design phase of the proposed road. Status of Line A is unsatisfactory. The road has been built for many years. It is too narrow and has too many flections. Its traffic is congested and there exists accident risks on many sections. Therefore, the road is going to be expanded and upgraded at this time. Restricted by the land utilization status along the road, constructing a completely new road in adjacent areas is impractical and unreasonable for much demolition and other environmental impacts. So Line A is proposed to be built basically following the original route this time, making some curve cut-off at some curves. It will improve the traffic safety, and decrease noise causing by brake and hooting, improve the ambient air and acoustic environmental quality around the road as a result. Line B is a completely new road to be built. According to the original scheme, the right pier of Zhongba Bridge is located on B1+500 of the proposed road, and the 503 Workshop of Wuliangye CO. Ltd., Lying in B2+000~B3+521.21, need to be demolished. Considering the impact is significant, the original scheme need to be regulated. If adjust the road section towards the downtown, it will cause more demolition, and the unique recreation function of the riverside road is lost, for it is far away from the river. If the line is removed towards the river, the problems above can be eliminated. Although the road is still beyond the national natural reserve, but it is more close to the reserve, and much more attention needs to be paid on the reserve protection during construction period. After careful comparison, it is considered that the impacts of the latter scheme are smaller on the whole, and can be decreased or mitigated after taking some control measures. Finally, after consulting with owner and design institute, the scheme which is closed to the river is adopted. But it needs to optimize construction scheme and restrict construction activity so as to decrease the adverse impacts of the scheme at the lowest. Additionally, the route of the proposed road bypasses the protection scenic spots, cultural and historical sites, such as Luibeichi Park and Baitashan scenic spot. It can avoid large social and ecological impact, and is reasonable from the view of the environmental protection.

3.3 Comparison of the design schemes 3.3.1 Lane comparison of line A Based on the traffic volume analysis, both two-lane scheme and four-lane scheme can satisfy the traffic demand of Line A. Two schemes for Line A are compared in condition that the route keeps unchanged.

33 Scheme 1 (combined 4/2 lane) : The cross section of the road from A0+000~5+160 is designed as 4 lanes and 15m wide due to a relative larger traffic volume; while 2 lanes and 10m wide from A5+160~6+688.51 where the traffic volume is little. Scheme 2 (2 lanes) : The cross section of the entire road is designed as 2 lanes and the width will vary according to the traffic volume in different sections.

Table 3-2 Comparison of lane schemes of Line A

Item Scheme 1 Scheme 2 Excavation (m3) 214954 154300 Fill (m3) 380620 330400 Land occupation (ha.) 16.14 15.36 Traffic capability (pcu/h) 3514 1562 Traffic volume in long term (pcu/h) 2700 1440 Traffic time saving in long term (pcu·h/d) 3745 1839 Kilometers saving in long term (pcu·kilometre/d) 86926 52155

Table 3-2 shows that the quantity and land occupation area in Scheme 1 are little bigger than that of Scheme 2, it can be concluded that soil erosion impact in these two schemes are similar. According to the on site investigation, residential buildings along the last section of Line A (A5+160~A6+688.51) are dense and very close to the existing road. As 4-lane road will cause much more demolition and resettlements, 2-lane design is considered to be reasonable when it meets the demand for traffic volume at the same time. In the upper section of Line A (A0+000~A5+160) , most residents are centralized along the section A3+800 ~A5+160. As it is not large-scale, there will not be too much resettlements when the upper section upgrading from 2 lane to 4 lanes. What is more important, seen from the planned road network of Yibin, Line A and Guandoushan Tunnel is the only road which connects Jiucheng, Jiuzhou with Baisha Industrial Park. In the long term, the traffic volume of Line A and Guandoushan Tunnel is very large. There is no traffic capability reserve for Scheme 2. The maximum traffic capability is 3600 Pcu/h for the Scheme 1. It can not only meet itself demand for the traffic volume increase in the future, but also can release the traffic pressure of Guandoushan Tunnel and keep some reserve for the future. The 4 lanes of Line A can shunt traffic when the traffic is interrupted or restricted in other city roads, such as maintenance or collapse period of Guandoushan Tunnel. It is obvious that scheme 1 (combined 4/2 lane) is more favorable for the improvement of urban traffic network. It can reduce start times of vehicles and the running time on road, and is helpful to decrease the exhaust emission and noise pollution. With comprehensive consideration, the combined 4/2 lane scheme is recommended.

34 3.3.2 Comparison of the cross section design at A0+560~A1+000 Two proposals are drawn out for the section of A0+560 to A1+000. Proposal 1: No tunnel, widen the existing road to bio-direction 4 lanes. According to the detailed analysis of the landforms and features of the road section, the construction condition of the Proposal 1 is satisfied. Proposal 2: tunnel construction. Adopt separate type of road section. The tunnel is built on the left part of the road, while the right part of the road is basically reconstructed along the original road. The tunnel is designed as 370m long, 11m wide and 5m high. The Proposal 2 can upgrade the technical standard of the left part of the road section. The comparison of the environmental impacts for the two proposals shows in Table 3-3.

Table 3-3 Environmental impacts comparison of the two proposals at A0+560~1+000

Proposal 1 Proposal 2 Advantage Avoid the relocation of Cuiping Glassworks Protect the natural slope along the road Occupy some flood lands due to the outward relocation of the road; relocate Cuiping Glassworks; Have some potential effect to ‘the national Disadvantage cause the soil erosion and vegetation natural reserve of rare and specific fish in the destroy due to the tunnel excavation upper reaches of the Yangtze River’ during construction phase

It can be seen from Table 3-3 that Proposal 1 has small resettlement and soil erosion impacts, but the quantity of backfill and retaining wall construction is larger than Proposal 2, for its outward removal to the river. On the whole, Proposal 1 will save about RMB14,000,000 than Proposal 2, the construction of 370m long tunnel. At last, Proposal 1 is chosen from the point of comprehensive environmental protection and economy. But the construction arrangement should be optimized and the construction activities restricted during the construction phase, so as to decrease the adverse impacts at the lowest. 3.3.3 Pavement material alternatives Asphalt concrete pavement and cement concrete pavement are compared in the project. The asphalt concrete pavement is recommended, because of its numerous merits as follows: (1) comfortable driving; (2) small noise; (3) tidy road surface ; (4) short construction period; (5) not sensitive to the differential settlement of the filled area; (6) Very convenient maintenance. (7) The asphalt concrete pavement is recommended from the view of environmental 35 protection.

36 4 Environmental status of the Project Area

4.1 Natural environment status 4.1.1 Geographic location The project is located in Yibin City of Sichuan Provinces, where is 300 km apart from the capital city-Chengdu. Lying in the south of Sichuan, Yibin is situated in the joint of Sichuan, Yunnan and Guizhou Provinces and in the convergence zone of the Jinsha River, the Min River and the Yangtze River. It stretches from 27e50’ north to 29e10’north of latitude and 103e36’ to 105e20’ east of the longitude. It is joined with city in the east, district of Yunnan Province in the south, Liangshan Yi Autonomous Region and city in the west, city in the north. Covering an area of 13,283 square km, it extends about 135.2 km from east to west and about 150.4 km from north to south. It is an important transport centre at the juncture of Yunnan, Guizhou and Sichuan Provinces, and is also an important part of resource and ecosystem protection barrier along the upstream of the Yangtze River. The project involves two parts, namely Line A and Line B. Line A is laid along the left banks of the Min River and the Yangtze River, extending from east to west, starting from the end of the Min River North Bridge and ending at Tianyuan Co, Ltd. Line B is laid along the south banks of the Jinsha River, extending from east to west, starting from the Cultural Square of South Bank and ending at the 4th Water Factory. The geographic location of the project is shown in the attached Figure 1. 4.1.2 Landforms and physiognomy The hypsography of Yibin City is high at south and north while it is low at the middle, slopping from west to east as a whole. The highest point in the City is the Fojian Mountain, which is 805.5m above sea level, and the lowest place is the Songjia Village, with the altitude of 254.5m. Taking the Guandou Mount - Cuiping Mount as boundary, the terrain in southeast of Yibin belongs to Chuandong parallel mountain vale zone, and it belongs to Fangshang hill zone in the southwest. The area between the Guandou Mount and Cuiping Mount is river vale zone, where the Min River is passing through. So there are four types of landform in the city, involving low-hill, hill, slot vale and river vale. 4.1.3 Geologic environment 4.1.3.1 Geologic structure

37 Influenced by the parallel fold in the east of Sichuan, the geological structure of Yibin constitutes of two small parallel anticlines extended from the northeast to southwest and a small syncline, which divide the whole city into irregular bandings and blocks. One anticline arises from Jinping in the northeast, stretching west to Cuiping Mount, named Chuandong Mount Anticline. The other arises is from Sheep Village in the southwest, reaching Nanguang Town, named Qixing Mount Anticline. Among the two anticlines, there is Longtou Mount Syncline parallel to them, which is from Gaodian Village in the northeast to Baishachang in the southwest. In addition, there are Panlong Mount Syncline and Dengguan Anticline parallel with it at the northwest of Guandou Mount Anticline. 4.1.3.2 Stratum lithology According to the stratum partition of Sichuan, Yunnan and Guizhou Province, the stratum of Yibin City belongs to the Luzhou subzone of Yangzi zone in . Because of the special geologic structure of Sichuan Basin, the red mudstone, sandiness mudstone and sandstone constitute the mutual deposit layer. By reason of the big difference in dryness and wetness of environment, the magenta soil is in the northwest and moister, while the brown-purple soil is in southeast and drier. The outcrops from old to new are the Xujia

River Group of Triassic (T3) , Jurassic system (J) , Guanjia Group of Mesozoic Cretaceous

(K2) and the fourth Cenozoic (Q) . 4.1.3.3 Hydrological geology The rainfall and rivers are the main sources of groundwater in Yibin. The quality of groundwater is related to the lithology of stratum. The ground water in the belt from Jingzichang to Qiuchang imbeds in the holes of mantlerock with low water level. The groundwater is abundant in the shaft of Xinzhong - Qiuchang Syncline and the cove of Guandou Mount Anticline - Nanguang Anticline, containing heavy calcium carbonate. Similarly, the groundwater imbedding in the periphery of the anticline near southwest and Songjiachang contains heavy calcium and magnesium. According to the geology reconnaissance report, Line A is located on the slope bordering the back edge of Class sidestep at the north bank of the Yangtze River. There is no large active zone of fracture nearby and the geology structure is rather stable. The stability of Line A is affected a little by ill engineering geology phenomena except the impact of Mount Fracture is correspondingly large. The geology structure of Line B is simple and stable, without any engineering geology phenomenon having been found, which is harmful to the stability of road.

The earthquake intensity of the construction area is grade .

38 4.2 Ecological environment 4.2.1 Climate Yibin city belongs to subtropical humid monsoon climate zone with distinct seasonal changes. The average frost-free period is long, as well as the sunshine, heat and rainfall are abundant. The average temperature is 17.8 , while the highest temperature is 38.6 and the lowest, -2.6 . The rainfall is uneven during different seasons in a year, with the average value of 1262.8 mm. Almost 70% of the rainfall concentrates in the term from June to September. The relative is 83%. 4.2.2 River system and hydrology 4.2.2.1 River system The Jinsha River, the Min River and the Yangtze River cross the northern part of Yibin City. There are totally over 600 big or small tributaries of the three major rivers. The annual average runoff at the junction of the Jinsha River and the Min River is 7,510m3/s. The amount of water pass through the territory of Yibin City is 240.125 billion m3 in a year. The characters of the three rivers are shown as follows: (1) The Jinsha River The Jinsha River comes into the city from the southwest. Its length in Yibin city is about 12 km, with the fall of 2.7m. The average gradient is 0.3 , and the annual average flow is 4,763m3/s. (2) The Min River The Min River enters the urban area from the northwest passing Gaochang in Yibin County. The reach length in the city is about 25.2 km, while the fall is about 9.1m. The average gradient is 0.36 , the annual average flow at the entrance is 2738m3/s with 2747m3/s at the estuary. (3) The Yangtze River The Yangtze River arises from Hejiangmen in Yibin where the Jinsha River and the Min River converge, and leave the city at Songjia Village. The reach length in Yibin is about 30.4 km, and the fall is 8.5m. The average gradient is 0.28 . The annual average flow at the entrance is 7510m3/s, and 7637m3/s at the leaving section. The average flood level is 274.77m, while the average low water level is 258.12m. The highest amplitude of flood level is 13.29m in history, and the historical lowest amplitude of low water level is 2.06m. 4.2.2.2 Hydrology The depth of runoff in Yibin city presents the same tendency with the distribution of rainfall. The annual average depth of runoff is 450 550 mm. The historical flood level in

39 Yibin City is shown in Table 4-1. Table 4-1 The historical flood level investigation in Yibin City Year 1644 1892 1905 1917 1931 Flood Level (m) 258.03 282.34 284.84 283.36 282.13

4.2.3 Vegetation and soil Little primeval vegetation remains in existence in Yibin today. Most of the remains to be found in Pingshan Laojun Mountain, Xingwen Xianfeng Mountain and Junlian Daxueshan Mountain, etc, is the secondary and manual growth after the ruin of primeval vegetation. In the city, the subtropical secondary- growth evergreen coniferous vegetation is broadly growing with specialty of the wide-spread. In 2003, the total rate of the forest cover was 34.53%. The whole land can be divided into three vegetation districts: (1) the eastern slope of Huangmaogen vegetation in Pingshan. It mainly covers the areas of Xinshi, Zhongdu, Longhua in Pingshan and Shangzhou in Yibin County, etc, with huge mountains, clear perpendicular distribution and rich variety of forest vegetation. (2) Northern slope and Western end of Loushanguang vegetation. It mainly contains Junlian, Gong and Xingwen Counties, most of and part of Pingshan, Yibin, Changning and Jiangan Counties. This district is full of hills and deep valleys. Lowland evergreen broad-leaved trees, coniferous trees and bamboo are the major plants growing in the areas less than 1500m altitude. The thermopile plants of Southern plant communities in subtropical areas are common in low-lying valleys. (3) The lowland and hill vegetation at the upper reaches of the Yangtze River. It mainly distributes in Cuiping, Nanxi and the parts of Changning, Yibin and Gaoxian Counties. The main types of vegetation are bamboo, evergreen broad- leaved trees, coniferous trees, and subtropical shrubs and bushes. According to the thorough statistics of the two general surveys on soil, the whole soil area in the city reaches 107,330,000 hectares, which is 80.5% of the whole land. There are six soil species in the city, and their actual areas are as follows: Purple soil of 767.8 thousand ha., Paddy soil of 267.9 thousand ha., Yellow earth of 238.8 thousand ha., Yellow slate gray soil of 74.4 thousand ha., Yellow-brown earth of 17.7 thousand ha., New alluvial of 6.8 thousand ha. 4.2.4 Bio-diversity The plant resource is rich in Yibin City. It includes more than 5,000 species of plant, with 800 species of crops, 1,001 species of the tree, 58 species of bamboo, 260 species of grass, 329 species of natural spice and 15 species of national rare and special plant (Some are manual planted.) like gingko, cycad, metasequoia and so on. The forest area within the boundaries of Yibin city is 340,002 ha., and the forest coverage rate is 34.02%. The number of wild animal species is 374, with the protective beasts of 63 species, birds of 250 species, the crawler of 36 species and the amphibian of 25 species.

40 According to the on-the-spot investigation, because of the dense population and intensive human activities in the urban area, most of the vegetations along the proposed road are manual planted, and no rare and special animals or plants have been found in the assessment area of the proposed project. The reserve nearest to the proposed road is "the National Reserve of Rare and Special Fish in the Upper Reaches of the Yangtze River". According to expert’s consultation and confirmed by authorities, the proposed project lies beyond the reserve boundaries. Details sees section 4.2.5. Because of the environmental improvement in Yibin, it is pleasant to see hundreds of black-headed gulls, a common species of migrating birds, start to use the water bodies of Minjiang, Jinshajiang and Yangtze rivers as their stop over places each fall and again each spring. Since 2000, several hundreds of the birds have been seen in these seasons to make brief stops. 4.2.5 National reserve of rare and special fish in the upper reaches of the Yangtze River ‘The National Reserve of Rare and Special Fish in the Upper Reaches of the Yangtze River’ is established based on the adjustment of the National Reserve of Rare and Special Fish in Hejiang ~ Leibo Reach of the Yangtze River” in 2005 (Sees Appendix 8). According to the Overall Plan of the reserve (July, 2004), the reserve at the moment crosses Sichuan, Guizhou, Yunnan Provinces and City. It includes the following reaches: the reach from Xiangjiaba downstream of the Jinsha River to Masangxi in Chongqing City; the main and branches of Chishui River in Yunnan Province; the mainstream of Chishui River in Guizhou and Sichuan Provinces, the downstream of the Min River, the estuary area of Yuexi River, tributaries of the Yangtze River including the Nanguang River, the Yongning River, the and the estuary area of the Changning River. The total river length of the reserve is 1162.61km, all within the rivers proper, and the whole area is 33174.2ha. (Sees Fig.10). The main protection targets of the reserve are about 70 species of fish, giant salamander, otter and their main habitat, including protected rare fishes Paddlefish, Acipenser dabryanus(Dumeril), and Myxocyprinus asiaticus. According to the Overall Research Report of the reserve (July, 2004), their main living habitat is listed in Table 4-2.

1 There are 4 core zones in the reserve. One of them is the reach from Hengjiangkou, downstream of the Jinsha River, to Nanxi. The Line B and part of Line A of the proposed road project borders upon it. According to the collected data , consultation with fisheries experts and confirmed by the Sichuan administration bureau of the national reserve for rare and special fish (Appendix 9), the protected area of the reserve is defined as water bodies in the rivers below the 20 year flood level; while the proposed roads are higher than 50 year flood level, outside the reserve. Available data (reserve plan, study reports, etc.) and results of experts consultation show that there is no spawning ground or specific habitats of the rare fishes in the river sections adjacent to the roads. The protected fish species move in a large area in the river. According to a 2003 study, within a few days, a Paddlefish was observed to swim down to Chongqing and back, across several hundreds km. The positional relationship between the project and the natural reserve is showed in the attached Figure 9; the distribution of the spawning ground of the natural reserve is showed in the attached Figure 10. 4.2.6 Soil erosion According to the result of remote sensing and field survey, the soil erosion area of Cuiping district in Yibin City, where the proposed project is located in, is 643.37km2, accounting for 56.87% of the total area. The erosion gross is 2,817,400 ton, and the soil erosion modulus is 4,300t/ (km2·a) in Cuiping district. The mild erosion area reaches to 183.91km2, about 28.59% of the total, the moderate erosion area is 217.48km2of 33.80%, the intense erosion area is 224.84km2 of 34.95% and the extreme erosion area is 17.12km2 of 2.66%. The soil erosion is smaller in the northwest than that in other areas of the city. Except the residential area on sloping field and the industrial area along the rivers, the average gradient of the ground along the proposed roads is less than 10%. The main erosion mode in the construction area is hydraulic erosion including the surface erosion and the ditch erosion with some sporadic gravity erosion. There are natural factor and human factor in the reason of soil erosion. With the density and size of population growth, the phenomena like cutting down vegetation, opening up wasteland are still incessant after repeated prohibition. As a result of the unreasonable cultivation way and the abuse of agricultural chemical fertilizer and agricultural membrane, the soil hardens and soil property is destroyed to cultivate. At the same time, the soil erosion in the area is also caused by the geological faultage development in Sichuan Basin and mountain region around, combine with centralized precipitation.

4.3 Social economy 4.3.1 Administrative division and population Yibin City consists one central urban district and nine counties around. They are Cuiping

1 District, Yibin County, Nanxi County, Jiang’an County, Changning County, Gao County, , Gong County, and Pingshan County. The total area of the city is 13,283km2.

Among the infield, the paddy field is 25,073.8 ha., ladder ground is 790 ha. and slope farming land is 28,478.3 ha. (of which the land with the slope angle over 25eis 730.8 ha.) . 4.3.3.3 Mineral resource Yibin has rich natural resource and is the concentration area of energy and mineral resource in the south of Sichuan Province. 47 kinds of minerals source have already been explored. The total reserve of the coal is 5.3 billion ton, with the preservation reserve of 4.14 billion ton, accounting for 53% in Sichuan Province. Most of the coal is anthracite with good exploitation condition. The reserve of the gas is 25.2 billion m3, and it mainly distributes in the counties such as Jiang’an, Changning, Nanxi, Xingwen and so on. The reserve of the pyrite is 1.476 billion ton, 64% of that in Sichuan province. The total reserve of the halite is 10 billion ton. In addition, there are other mineral resources such as limestone, dolomite, quartz, calcites and so on, with huge reserve and good quality. 4.3.4 Municipal water supply and drainage 4.3.4.1 Municipal water supply and water source protection (1) Municipal water supply At present, there are four water supply works in Yibin City, respectively the 1st waterworks, the 2nd waterworks, the 4th waterworks and the Yibin County waterworks. The 1st waterworks is located in the Doufushi in Jiucheng, with the land occupation of 3 ha., taking water from the Min River. It can supply tap water of 50,000m3 per day for the Jiucheng and Zhongba District. The 2nd waterworks is located in the Dafotou in Jiucheng District, with the land occupation of 1.6ha, taking water from the Min River and supplying water of 50,000m3 per day for the Jiucheng. The 4th waterworks is located in the Xuetan in Nan’an District, with the land occupation of 4.7ha, taking water from the Jinsha River and supplying water of 100,000m3 per day for both the east district of Nan’an and the west district of Nan’an. The Yibin County waterworks is located in Boxi in Yibin County, taking water from the Jinsha River, and supplying water of 20,000m3 per day for the Yibin County. According to the on-the-spot investigation, when the 4th waterworks put into production, the old 3rd waterworks had been closed. (2) Drinking water source protection zone According to the on-the-spot investigation, the nearest water inlet to the proposed project is the one of the 4th waterworks. According to “Regulations of Drinking Water Source Protection of Sichuan Province” (approved by meeting of the Standing Committee of

3 People’s Congress of Sichuan Province in 2004) , the scope of the first class water source protection zone of the 4th waterworks involves the reach from 1000m upstream to 100m downstream of the water inlet in the Jinsha River and the land area within 200m along the bank. The end of Line B is located on the bank 150m downstream of the water inlet, so the proposed project is outside of the first class water source protection zone of the 4th waterworks. 4.3.4.2 Status for sewage discharging and treatment At present, the drainage system has formed in Jiucheng, Jiuzhou, the east district of Nan’an and Baixi districts. The rainwater and sewage flow separately in most of districts, except in the Jiucheng district, part of Jiuzhou district and most of old Boxi district. There are three wastewater treatment plants (WWTP) completed or on the stocks in Yibin City. The Nan’an WWTP is located in Daxikou in the Nan’an district. It shall treat the sewage from the new area of Nan’an district and Dadipo. Its designed treating capability is 50,000t/d. The construction started on December 26, 2001, and most of the plant buildings have been set up now. The equipment erecting will be finally completed in December, 2005. The Yangwan WWTP is located in the downstream of the Jiuzhong district, treating the sewage from Jiuzhou, Jiucheng and Zhongbu districts. The designed treatment capability is 60,000t/d. The preparation work for construction has been finished. The construction is planed to start at the end of October, 2005, and be completed in 2006. The Baisha WWTP is located in the downstream of the Baisha industry garden area. The design treatment capability is 80,000t/d. The WWTP is at the stage of feasibility study. 4.3.5 Public health The main epidemic infectious diseases and the endemic diseases in Yibin are malaria, ancylostomiasis, scald head, spirochaetosis, and schistosomiasis and so on. By the end of 2002, the amount of medical institutions in Yibin has expanded to 149, providing with 7,560 sickbeds and 16,569 nurses or doctors. That means one doctor for every 309 people and one sickbed for every 678 people. 4.3.6 Transportation condition The transport network of Yibin is composed by the road, railway, ship and plane. It has formed the rudiment of three-dimensional transport network with "the road, the railway, the ship and the plane". At present, Yibin has formed a highway network with Yibin City as the center, two national ways (G240, G213) and four provincial ways (S206, S307, S308 and S309) as the framework and county-and-rural level roads as links. By the end of 2002, the total length of the road including village road has reached to 4,352km, and the total length of the road

4 above Class has reached to 2,445km. The 85% of the villages have roads. The present road from the north bank of the Min River Bridge to the Tianyuan Co.Ltd is bad, sinuate and crowded. The construction of Line A shall improve the tracffic condition and benefit to the implement of city planning. There is no road from the Cultural Square of South Bank to the 4th waterworks. The construction of Line B shall mitigate the encumbrance to the cooperation between the city and the countryside. 4.3.7 Scenic spot and historic site According to the on-the-spot investigation, there is no scenic spot and historic site of county lever or above distributing in the construction area. The most nearest scenic spots are the Liubeichi Park and the Baitashan Scenic Spot with some historic site in the parks. 4.3.7.1 Liubeichi park The Liubeichi Park is located near the Lixu Road Bridge on the north bank of the Min River. It is joined with the Diaobai Road in north, the Yangwan Production Team in west, Peixi in east and Tianzhu Mountain in south. The official approval of the Liubeichi Park Overall Plan was given by Sichuan Construction Bureau in December, 2002 (see Appendix 10). According to plan, it is a comprehensive park at city level with the function of visit, tour and leisure. It relies mainly on such human cultural sights as history and culture, etc., merging with such natural landscape as the ground form, vegetation, etc. The main historic sites in the park are Luibei Pool and the Chengxiang Shrine. Luibei Pool was built in 1089, designed by Huang Tingjian who is an poet living in Northern . Chengxiang Shrine was firstly built in Song Dynasty to commemorate Zhu Geliang who is the prime minister of Shu State in Three Kingdom Period. In 1850, the shrine was destroyed by war and rebuilt in 1856 in . Both the two historic sites are open to the visitors for sight-see. The Liubeichi Park is out of the construction scope. Its southern gate is 20m far away from the road center line near A0+040. The cultural relics- Chengxiang Temple is 170m away from the road in linear distance and at less 10m above the surface of the road. The other scene points are above 200m from the road. The positional relationship between the proposed road and the Liuchibei Park is shown in Attached Figure 11. 4.3.7.2 Baitashan Scenic Spot An official approval of the Baitashan Scenic Spot Overall Plan was given by Yibin people’s Government in November, 2000 (see Appendix 11). According to the plan, the Baitashan Scenic Spot is a scenic spot with the natural landscape and integrated service with the function of tour and leisure. The Baitashan Scenic Spot is located in the east of the Jiucheng District, and border upon the Liubei Park. It is joined with the Min River in north, Cuike Mountain in east, the line

5 of Chenjiawan - Miaoziwan - Erdengyan in south, and the Yingpan Mountain in west, with the total area of 2km2. The center area of the park is 0.8km2 with the White Pagoda as the center. The landform of the park is foothill. It is higher in the west and is lower in the east, presenting the posture of two mountains in two sides with one valley in the middle. The highest altitude in the park is 543m, and the lowest is 260m. The altitude of the top of the pagoda is 454.58m. The Line A shall pass by the foot of the hill, the altitude difference between the pagoda and the road surface is 160m and linear distance of 600m. The positional relationship between the Baitashan Scenic Spot and the proposed road is shown in Attached Figure 12.

4.4 Environmental quality situation 4.4.1 Water environment quality According to the monitoring date, the water quality of the Jinsha River, the Min River and the Yangtze River is fine in the area of Yibin as a whole. Most indexes of water quality meet the Class III standards of “Environmental Quality Standards for Surface Water” (GB3838-2002) except the coliform, oil and the total phosphorus which may be affected by the urban sewage discharge. There is no wastewater treatment plant in function in Yibin City now. The monitoring date of the water quality of the rivers relating to the proposed project is shown in Table 4-3.

The monitoring date shows that the Leq (A) values of monitoring points on Line A meet the “Standard of Environmental Noise of Urban Area” (GB3096-93) , except the 799 kindergarten, at which the noise at nighttime exceeds the applicable standard slightly because of the traffic noise. All the Leq (A) values of monitoring points on Line B exceed the applicable standards, especially the nighttime values exceeding seriously at 5 ~12.5dB. According to the on-the-spot investigation, the monitor data can present the situation of acoustic environment quality along the route on the whole. The main reasons for excess are as follows: The acoustic environment quality of the No. 405 hospital is mainly affected by the heavy traffic noise of the two roads nearby. The excess at the Shangdukou Community is mainly caused by the awful traffic condition there. In addition, the Nan’an Elementary School shall be resettled according to RAP of YBRERP, so it will not be considered in this EIA. Its monitoring data can be used as the background value of nearby area. 4.4.4 Eco-environment quality Yibin City is the important component part of the ecological protection barrier along the upstream of the Yangtze River. The eco-environment quality in Yibin has been improved greatly because of the performance of the mitigation to soil erosion and protection to the environment. But as a whole, the eco-environment quality is still under the threat of the 9 destruction of forest, soil erosion, flood, drought, landslide and so on. 4.4.5 Social environment quality Yibin city is the communication hub and trade center on the juncture of Sichuan, Yunnan and Guizhou Provinces. Yibin is fast developing into a regional center city with leading industries including energy, foodstuff and chemical industry and featured by wine industry. But the extractive industry is still weakening in Yibin City and the industry also is lack of advanced technology. The economic structure is unreasonable and it still needs large fund to get rid of the predicament in the development.

4.5 Screening of the safeguard policies of the world bank

Of all the safeguard policies of the World Bank, OP 4.01 "Environment Assessment" is a basic requirement. OP 4.01 is also the key content of the EA documentation. The other safeguard policies are also screened in this assessment and applied if necessary. The screening is based on detailed site investigation of the physical, biological and socio- economic environments where the project is located and the environmental impact feature of this project. Relevant government agencies are also consulted during the screening. The results of screening are shown in Table 4-7.

4.6.4 Sensitive spots of ecological environment According to on site investigation, the sensitive spots of ecological environment in the assessment scope of proposed project are mainly the spots border upon the project such as ‘The National Natural Reserve of Rare and Peculiar Fish in the Upper of the Yangtze

13 River’ and ‘the Baitashan scenic spot’. The construction activities which possibly affect the environment sensitive spots mainly are the excavation and filling activities and so on. 4.6.5 Sensitive spots of social environment The proposed construct pass through the Yibin city, the demolishing quantity along the route is bigger, the demolishing business, institution and inhabitant of this project are the social environment sensitive object. In addition, the business and institution unit which are affected by construction and operation along the route, such as Yibin Tianyuan Co. Ltd, Yibin Power Generation Co. Ltd and so on, are also the social environment sensitive object of the project. The Liuchibei Park and the Baitashan Scenic Spot are not in the scope of land acquisition and demolition of Line A, and the project construction will not directly affect them. The social environment sensitive spots in the assessment range are shown in Table 4-11. The location of the social environment sensitive objects is shown in Figure 7. The photos of the sensitive spots are shown in Figure 8.

15 5 Environmental Impact Assessment

5.1 Analysis of impact on water environment 5.1.1 Impact during construction phase 5.1.1.1 Pollution source The sand and gravel materials would be purchased from materials merchant, and there is no corresponding construction sewage in the project. Garages in the city zone can afford the repair of all the construction machineries. It needs not to set garages in construction area and no oily sewage will be yielded. This construction located in the city zone where the web of sewage pipeline is maturity. It is possible to merge domestic sewage into the web of sewage. The impact of domestic sewage can be very limited. The pollution to the water environment mostly comes from the soil erosion in the excavation and waste soil disposal activities during construction phase. According to the local terrain, characteristics of precipitation and construction, the predicted quantity of soil erosion is 14110t during construction phase (details are listed in section 5.4.3). 5.1.1.2 Prediction of water quality According to the two dimensional steady transportation model commended in the Technical Guidelines for EIA - Surface Water Environment (HJ/T2.3-93), the prediction model is listed as following: c Q   uy 2   u(2B − y) 2  c(x, y) = p p exp−  + exp−  π      H M y xu   4M y x   4M y x  Where: c üpollutant concentration (mg/L); ü c p concentration of discharged pollutant (mg/L); ü 3 Q P flux of wastewater (m /s); ü 2 =+ 12 M y transverse diffuse coefficient (m /s), MHBgHIy (0.058 0.0065 )( ) ; J ügradient of riverbed (m/m); g üacceleration of gravity (m/s2); u üaverage velocity of river flow (m/s); B üwidth of river (m); H üaverage depth of river (m). According to the predicted soil erosion quantity in the peak construction period, taking the most disadvantage condition into account, assume all the soil erosion is occurred in dry

16 season (Nov. to Apr.) and will become SS. According to the annual precipitation distribution, assume all the rainfall concentrate in 100 continuous days and 3 hours per day. The maximum hourly soil erosion amount in Line A is 17.5t/h, while Line B is 3.6t/h. Ignoring the sedimentation or degradation effect, and assuming the source to be a bank centralized discharge, the predicted impact on sediment during construction phase are shown in Table 5-1. Table 5-1 Predicted results of water quality Averaged RiverDischarge River River Route GradientRoughnesswidth Intensity Prediction Result Nearby flow (m) (g/s) (m3/s) longitudinal: the concentration increment of SS less than 10mg/L beyond 830m downstream the

A Yangtze discharge site; e 7510 0.0003 0.027 455 3854 n i River transversal: the concentration L increment of SS more than 10mg/L limited in 11m close to bank, which is 2.4% of the river width at this section longitudinal: the concentration increment of SS is less than 10mg/L beyond 70m downstream the

B Jinsha discharge site; e 4763 0.0003 0.025 247 997 n i River transversal: the concentration L increment of SS more than 10mg/L limited in 2.5m close to bank, which is 1.0% of the river width at this section

According to the analysis above, construction would not cause significant impacts on river quality, as the pollution plume which defined as SS 10 mg/L higher than the baseline concentrations in the river is limited closely to the river banks. Such level of increase (10 mg/L) in SS in the river can hardly be considered significant either, as during the flood season each year, the SS in the rivers can be hundreds mg/L higher than the baseline concentrations or even higher. 5.1.2 Impact during operation phase

17 The proposed trunk sewer separates the rainwater and sewage. All the sewage will be collected and transferred to the WWTP, which will avoid the pollution cause by concentrated discharge along the road. Service zone and management station are not include in the project, so there is hardly domestic sewage yielded in operation phase. The water pollution will mainly be caused by the road surface runoff. Besides, the pollution may come from the traffic accident of vehicles carrying the dangerous liquid cargo. More detailed impact assessment about such accident is shown in later section. 5.1.2.1 Impact of the road surface runoff The pollution of the surface run-off during operation phase is mainly caused by the dust and pollutants in vehicle exhaust gas which can fall on the road and flow into the river with rain. According to the research of the Environmental Engineering Institution of Chang’an University, the average concentration of these pollutants is shown in Table 5-2.

Table 5-2 Average concentration of pollutants from the road surface run-off

Item CODCr Oil SS Average concentration during 120 minutes (mg/L) 107 11.25 100

According to the area of road surface, the calculated volume of 2 hours’ storm rainfall is respectively 5,016m3 in Line A and 3,521m3 in Line B. The runoff coefficient is assumed to be 1.0 and the collecting time is ignored, the runoff flow is respectively be 0.7m3/s in Line A, 0.49m3/s in Line B, which last 2 hours. The long term average flow on the project section is 7,510m3/s in the Yangtze River and 4,763m3/s in the Jingsha River. The ratio of run-off to the river flow is respectively 1: 10779 in Line A and 1: 9739 in Line B. The discharge intensity and the ground concentration of river water quality are shown in Table 5-3.

Adopting the two dimensional steady model, the predicted results of river water quality are listed in Table 5-4.

It within 1m close to bank, 13.5m close to bank, 5.5% of also meets the water quality 0.4% of the river width the river width. standard Class .

According to the above tables, the pollution of surface runoff is mainly oil, whereas the impact of COD and SS is minor and very limited. The affected scope of oil will be 450m×10m around the discharge site in Line A, and 270m×7m in Line B, all of which centralized in 10m scope close to the bank. 5.1.2.2 Impact by centralized sewage discharging Sewage pipeline is laid along the road, and it will be joined into the urban sewage system after the construction of the road. The sewage pipeline in Line A can be divided into three segments. The pipeline of segment A1 (A0+000~A0+400) would transport sewage to Yangwan WWTP which has been constructed from 2005 to 2006. In segment A2 19 (A0+400~A3+820), there is no pipeline laid. And the pipeline of segment A3 (A3+820~A6+668.51) would transport sewage to Baisha WWTP for which the feasibility study has been carried out. The pipeline in Line B would transfer sewage to Nan’an WWTP which has been constructed from December 26th 2001 and will be fully completed in December 2005. The construction of the pipeline in segment A1 and Line B would be completed before that of the road which start from 2006 and end to 2008. After the construction of the two pipelines, sewage can be transferred to the wastewater treatment plant without any impact on water environment. In view of Baisha wastewater treatment plant will not complete when the pipeline of segment A3 is finished, the concentrate sewage in the pipeline would discharge directly. According to the planar steady commixture mode commended in the Technical Guidelines for EIA - Surface Water Environment (HJ/T2.3-93) , in the case of sewage is discharged directly in the segment A3, the water quality beyond 10m around the outlet of the sewage would meet the Environmental Quality Standards for Surface Water (GB3838-2002) Class . Although the impact area is small, protection measures must be taken for the sake of the natural reserve nearby.

5.2 Air impact assessment 5.2.1 Meteorological conditions

The average wind speed for several continuous years in Yibin is 1.0 1.3m/s and average temperature is 17.8 , with frequencies of calm wind occurrence yearly of 34% ~ 53%. This indicates that the local climate tends to be stable in general. It is not a favorite condition for air pollutants to be dispersed and diluted once emitted from motor vehicles and other sources. The primary wind direction all the year round is WN, second is W and EN. In summer, there is thundershower with gust, maximum wind speed at 16.0m/s and the wind direction is E. 5.2.2 Air impact during construction phase 5.2.2.1 Dust Dust will be the primary air contaminant during the construction phase. The sources of the dust will primarily be building demolition, materials transportation and the activities such as load and unload materials, blending and so on. The factors affected dust will include climate conditions, mainly wind speed and directions and moisture in the ambient air, and the type of construction activities. Without any mitigation and when the wind speed is 2m/s, the TSP concentration value in the air is more than 1.7mg/m3 at 100m leeward material mixing site and about 0.5mg/m3 at 150m. The

20 values with the same distance in leeward direction of transportation road are 10mg/m3 and 5mg/m3 respectively. All the above based on the experience from similar projects elsewhere. This indicates that air pollution caused by the dust from the materials transportation is much worse than that from materials mixing site.

21 5.2.2.2 Asphalt smoke Asphalt smoke is synthesized smoke which is liquid hydrocarbon grain matter mixing with little gaseous hydrocarbon grain matter. It can cause headache, eyesight attenuation and so on through respiratory tracts and polluting skin. Therefore, it is necessary to control the discharge of asphalt smoke during asphalt mixing process. Now, the asphalt mix station is commonly close with dust catcher, and the asphalt admixture would be carried to construction site by heat-resistant container in highway projects, so the discharging concentration of asphalt smoke is low. As reference to relevant reports for similar project, when wind speed is between 2m/s and 3m/s, asphalt smoke pollution affected distance is about 100m leeward. In this project such construction technology will be considered first, impact on the surrounding environment is little. According to the construction plan, the asphalt mixing station will be sited at A0+480 of Line A, where is a great stockpile area now. None resident is in the 200m leeward area, so in the Asphalt mixingprocess a small quantity of asphalt smoke discharge will not affect sensitive spots. 5.2.3 Air impact in operation phase It is expected that the TSP concentration will be small on asphalt concrete road surface, and the main contaminant is NOx produced by the discharge of the vehicle exhaust gas in operation phase. 5.2.3.1 Emission intensity prediction

The NOx intensity from vehicle emission on road is forecasted by the model as follow, according to the Specification for Environmental impact Assessment of Highway ( JTJ005-96) .

3 = −1 Q ∑3600 Ai Ei i=1

where: QüNOx intensity in n year, mg/ (s·m) ; AiüTraffic flow of i type vehicle in n year to be assessed, vehicle/h, defined by the Feasibility Study Report of YBRERP;

EiüNOx emission factor of individual vehicle of i type in n year, mg/ ( vehicle·m) The emission intensity predicted results for short-term (2009), medium-term (2014) and long-term (2024) is listed in Table 5-5.

Modeling results show that motor vehicle NOx emission intensity will be increased in prediction terms along with the growth of traffic volume. However, the prediction doesn’t consider the improvement of motor vehicle exhaust standard and the implement I/M plan. The second stage discharging restriction of motor vehicle exhaust standard has been carried out since July 1st, 2005. Meanwhile, Yibin city has strengthened monitoring and managing to vehicle exhaust pollution in town from 2005. In this case, the factual NOx discharging amount in middle term will be smaller than the predicted results. 5.2.3.2 Diffusion intensity prediction Based on motor vehicle emission intensity predicted by the above model and the traffic volumes prediction, simulation is made for the atmospheric quality on both sides of the roads. CALINE4 model recommend by the World Bank is used to model the NOx diffusion, as follows. Divide road into a serial line-units, respectively calculate concentration of each unit at this point, then add up to calculate the total concentration of the vehicle exhaust on the whole road to the point. Each line-unit is treated as a finite line source (FLS) which is centred at line-unit, and direction is vertical to wind direction relevantly. Take the line-unit centre as coordinate origin, leeward direction as X axis positive direction, set up plane coordinate series to each line unit, treat the vehicle exhaust in each one as discharging along FLS, then imitate diffusing using Gauss Model.

The points of prediction are all assumed to be 1.5 m above the ground. The background concentration input in the CALINE4 model was the average concentration of the state designated reference area. It considers the most unfavorable conditions refer to the motor vehicle traffic flows at peak hours and the most unfavorable meteorological conditions (calm wind, unfavorable wind direction, high stability and high mixing layer). The dispersion modeling results for both sides of project roads are shown in Table 5-6.

It can be seen from Table 5-6 that concentrations of NOx at peak hours on A0+000~ A0+640, A1+040~A1+800, A4+640~A5+130 sections 20m far away will exceed the Class 3 II standard 0.12 mg/m , The NOx discharge concentration beyond the distance of 20m are below the standards of Class II. On all overrun sections, the road face will be widened to 4

25 carriageways from 2 carriageways, and the traffic volume will have a great growth in operation phase than that at present. Accordingly, the emission intensity is enhanced. Otherwise, the discharge concentration would be affected by the road route, wind direction and so on. For example, the line at A1+040~A1+800 is half-round, which goes against the

NOx emission. None special sensitive spot (hospital, school, residential areas) is in the overrun areas. In the rest parts of Line A and all line of Line B, NOx discharge concentration are below the standards of Class II beyond the distance of 10m.

Moreover, except the southern gate of Liubeichi Park is within the overrun area, the NOx concentration of all the rest sensitive points areis below the standards of Class II.

5.3 Noise impact assessment 5.3.1 Noise impact during construction phase 5.3.1.1 Noise source In this project, construction noises mainly come from the working of construction machinery and the building dismantling. 1) Construction machinery Construction machinery includes bulldozer, excavator grab, road roller, road paver and so on. These kinds of machinery are the main source of noise during construction, the noise levels of which are listed in the Table 5-7. 2) Construction transportation Large number of material, equipment and soil should be transported to the appointed location. The conveyance especially the heavy self-loader would cause large noise impact on the acoustic environment along the road. The noise level of the heavy self-loader is listed in the Table 5-7. 3) Building dismantling Some building should be dismantled before the construction, and the noise will be generated at the same time. The noise level of which is shown in the Table 5-7.

Table 5-7 Source of construction noise Noise sources Distance to the source (m) Maximize noise (dB) Bulldozer 5 86 Loader 5 90 Excavator grab 5 84 Concrete agitator 2 79 Road roller 5 86 Self-loader 7.5 88 Road paver 5 87 Pile driver 5 96 Dismantle floor 25 95 Wall falling 25 100

26 5.3.1.2 Prediction of construction noise The construction is linear, and each of construction machines needs enough space to function. So all the noise source can be consider as spot source, and the impact of the noise will reduce as the growing of the distance. The noise attenuation formula is shown as follows:

= − r LA(r) LA(r ) 20lg 0 r0 where:

LA (r) —Noise level at the measure point with the distance of r from the noise source, dB (A) ;

LA (r0) —Noise level at the measure point with the distance of r0 from the noise source, dB (A) ; r—The distance to the noise source, m. According to the noise attenuation formula and the Noise Limits for Construction Site, the affected regions of the construction machinery noise are shown in the following table.

Table 5-8 Affected range of the construction machinery noise Construction Noise in different distance (dB) Standard value (dB) distance with no impact (m) machinery 10m 20m 40m 60m 80m 100m daytime nighttime daytime nighttime Bulldozer 80.0 74.0 68.0 64.4 62.0 60.0 18 117 Loader 84.0 78.0 72.0 68.4 66.0 64.0 28 281 75 55 Excavator grab 78.0 72.0 66.0 62.4 60.0 58.0 14 140 Self-loader 85.5 79.5 73.5 70.0 67.0 65.5 34 335 Road paver 81.0 75.0 69.0 65.4 63.0 61.0 35 199 Road roller 80.0 74.0 68.0 64.4 62.0 60.0 70 55 31 177 Concrete mixer 65.0 59.0 53.0 49.4 47.0 45.0 4.8 17.8 Forbi Pile driver 90.0 84.0 78.0 74.0 72.0 70.0 85 17.8 / construction

According to the table, the noise of the construction machinery can meet the Noise Limits for Construction Site (GB12523-90) out of 35m in daytime and 335m in nighttime without the obstruct such as buildings and trees. According to the noise attenuation formula, the noise of the construction machinery can meet the Standard of Environmental Noise of Urban Area (GB3096-93) class out of 335m in daytime and 1059m at night time; and meet the Standard of Environmental Noise of Urban Area (GB3096-93) class out of 188m in daytime and 562m at night time; and meet the Standard of Environmental Noise of Urban Area (GB3096-93) class out of 57m in daytime and 335m at night time.

At the distance of 100m to the construction site, the maximal noise can reach 70 dB (A) ,

27 which is almost accord with the Standard for Noise at Boundaries of Construction Sites. By the way, the results ignore the obstruct such as the terrain and buildings, compare with the similar situations, the final impact ranges and degrees should be much less than that were forecasted. 5.3.1.3 Impact on the sensitive spots along the route Because most of the sensitive spots along the route have distances less than 40m to the road (as shown in Table 4-7), acoustic environment around the sensitive spots such as schools and hospitals will not meet the requirement of applicable standards. The impact cause by the construction is temporary and will disappear after the construction finished. 5.3.1.4 Impact of construction noise at night According to the available prescription of Yibin, the construction should be halted at night form 22: 00 to 6: 00 and the impact on acoustic environment would not exist at night. But base on the construction experience, the construction at night is inevitable in the case of keeping the concrete casting continuous, decreasing the impact on the halting of the traffic, reducing the risk of construction or catching up the schedule and so on. Therefore, the resident near the construction site would be disturbed while sleeping, in which the elders, kids, patients and so on are much more sensitive to the impact. 5.3.2 Noise impact during operation phase 5.3.2.1 Noise source The acoustic environmental impacts are mainly caused by the traffic noise which associates with the load and the velocity of the vehicle. According to the Feasibility Study Report, the prediction of the traffic flux is shown in the following table.

Table 5-9 Prediction of traffic flux of line A and line B Operating phase Road section Short-term Medium-term Long-term

5.3.2.2 Prediction of traffic noise The impact of the traffic noise during the operating phase can be worked out according to the formula commended in Specifications for Environmental impact Assessment of Highway. Combine with the analogy and research, the noise prediction formula is shown as follows: (1) The equation for estimating the noise level at the measure point when i type vehicle

28 running in day time or night time

 N  ()L = L +10lg i  − ∆L + ∆L + ∆L −13 Aeq i w,i   distance longitudinal road surface  viT  where: i—Large-size, medium-size and small-size;

(LAeq) i—Noise level at the measure point when i type vehicle running in day time or night time, dB (A) ;

Lw,i—Average noise intensity of i type vehicle, dB;

Ni—Average hourly traffic flow of i type vehicle, pcu/hr;

Vi—Average running speed of i type vehicle, km/h;

T—Time for LAeq prediction, 1h; ∆ Ldistance —Attenuated level at the measure point with the distance of r from the i type of vehicle, dB (A) ; ∆ Llongitudinal —Amended value for the effect of longitudinal slope, dB (A) ; ∆ Lroad surface —Amended value for the effect of road surface, dB (A) ;

(2) Equation for estimating the noise level at the measure point during day time or nighttime:

0.1(L ) 0.1(L ) 0.1(L ) (L ) =10lg[10 Aeq L + 10 Aeq M +10 Aeq S ]− ∆ − ∆LL Aeq traffic 1 2 where:

(LAeq) traffic—Noise level at the measure point during day time or nighttime, dB (A) ∆ L1 —Amended value for the effect of road curve or limited route, dB (A) ; ∆ L2 —Amended value for the effect of the obstruct between the measure point and the road, dB (A) . (3) Equation for estimating the acoustic noise level ( ) 0.1 LAeq 0.1(L ) (L ) =10lg[10 traffic + 10 Aeq base ] Aeq com Where:

(LAeq) com—Noise level at the measurement point in day time or night time, dB (A) ;

(LAeq) base—Baseline noise level at the measurement point, dB (A) . The determination of the parameter in the above equations should be according to the Appendix E1.2 in Specifications for Environmental impact Assessment of Highway (on trial) (JTJ005-96) . In the prediction of traffic noise, the noise monitoring value can be regard as the baseline noise. Combine with the prediction of traffic flux, the noise level of the sensitive spots in

29 operation phase are shown in the following table.

34 5.3.2.3 Noise prediction and assessment for sensitive spots It can be drawn from above table, because of the growing of traffic flux in Line A, noise level increase obviously to the extent of 7 dB to 15 dB in long-term. And the noise level of common sensitive spot such as roadside dormitory of No. 779 Plant, the roadside dormitories of Changjiang Paper Industry Co., Ltd. and the roadside dormitories of Tianyuan Co., Ltd. exceed the Standard of Environmental Noise of Urban Area (GB3096-93) class ; the noise level of special sensitive spot like the 799 kindergarten exceed the Standard of Environmental Noise of Urban Area (GB3096-93) class , which exceed 10.6 dB in daytime and 12.6 dB in nighttime in long-term. The noise level of the sensitive spots in Line B such as the No. 405 Hospital, the roadside dormitories of Yibin Chemical Fiber Factory, and Construction Committee, and the roadside houses of Shangdukou Community also exceed the applicable standards. One of the important factors besides the close quarters between spots and road is the exceeding of the baseline noise level. The exceedance of baseline noise level would be 3.7 dB in daytime and 11.1 dB in nighttime at the No. 405 Hospital, and that would be 4.4 dB in daytime and 12.5 dB in nighttime at Shangdukou Community. The exceedance of baseline noise level would be 6.1 dB in nighttime at the dormitories of Chemical Fiber Factory. After the construction of the roads, the noise level would be increase obviously in Line A during the operation phase. Steps should be taken to reduce such impact in light of the condition of the spots.

5.4 Impact on eco-environment 5.4.1 Impact on the national reserve of rare and special fish in the upper reaches of the Yangtze River Confirmed by the Sichuan administration bureau of the national reserve for rare and special fish, the scope of the reserve is the water area below the flood lever with the probability of 5%, and the proposed project is on the land on or higher that flood probability of 2%, beyond or outside the reserve. The project construction will not affect the reserve directly. The reserve may be affected indirectly by the discharges of runoff containing suspended solids and/or oils during construction and operation. According to the analysis result of water environmental impact, the SS concentration may be raised due to the soil erosion during construction phase. However, the increase shall be limited mainly within the area near the riverbank with a plume of about 13m wide and 870m long. The affected range is small, when compared with the total river width of about 450m at this section and the annual mean SS concentration of 1720mg/L. Furthermore, the fish, particularly the large body protected fish live in the deep water zones in the middle of the rivers and there is no spawning ground or sensitive habitats in this section of the river, the

35 impacts, if any, to the fish shall be very limited during the project construction. Similarly, during the operation phase, the water impact by the road surface runoff shall be limited within a plume of 10m near the bank. The small increase in SS, oils and COD within the very narrow plume can hardly have any significant impact to the fish. Furthermore, the affected section is less then 15km, which accounts for 1.3% of the total protected river of 1162.61km. There are quite a few river sections as fish inhabits. The migrating or self-protecting capability of the fishes is rather strong. According to the result of sonar track experiment in 2004, the Paddlefish can migrate several hundred kilometers in a few days, indicating that the migration space is quite large. At the same time, there is no spawning ground of rare and special fishes in the river section adjacent to the proposed project. For the analysis above all, the contraction and operation of the project are not likely to have significant impacts to the fish. 5.4.2 Impact on terraneous vegetation and animals The proposed Line A is arranged along the existing road mainly. Affected by traffic, the ground cover is rare and there is no rare plants distributed. Line B is a new road and the vegetation coverage rate is higher in the section from Shangdukou Community to the No.4 water plant. Moreover, there is some cultivated land but no special plants found. The impact on vegetation comes from the destruction of the trees and underbrush which can mitigate soil erosion. At present, the human activities are quite active, as well as the traffic flow is large in the urban and suburb area where the proposed project located. The animals have been adapted to such conditions, so the noise of the running vehicles during the operation phase won’t affected the animals nearby too much. But the project construction may disturb the animals nearby, making them move to other place for a while. Besides, if there is no strict management, birds poaching may occur during construction. Some measures should be taken to protect animals and birds nearby like Black-headed Gulls. 5.4.3 Prediction of soil erosion Landform and surface coverage would be spoiled because of the excavation and backfill. The excavation and backfill segment will be exposed or incompact and will result in soil erosion after the construction is completed. 5.4.3.1 Prediction scope and period (1) Prediction scope The prediction scope of soil erosion is composed of the construction area and the direct affected area in the project. The construction area where is occupied permanently or expropriated temporarily can be divided into the permanent occupation area and the temporary occupation area.

36 The permanent occupation area is composed of the following parts: The construction in Line A will occupy an area of 18.14ha., which in Line B is 8.56ha.. The borrow pit beside the hill near the A3+400 will occupy an area of 1.5ha., and that of the waste disposal field is 0.158ha. The temporary occupation area can not be reckoned in the prediction scope because of most of the establishments and service would be provided by the special merchant and it is no need to set supporting facilities site. The direct affected area on the roadside is 3.22ha. The range is taken as 3m outboard and 2m inboard on the section of A0+400 to A3+800 and B0+400 to B3+440, where adjacent to rivers. As the other sections of the proposed road are mainly in the uptown areas, and there is little water and conservation facilities, the area is not be reckoned into the direct affected area. (2) Prediction period The prediction period can be divided into construction phase and operation phase. The construction phase is 3 years, from 2006 to 2008. Taking 3 years of operation phase into consider, and the prediction period of soil erosion is 6 years. 5.4.3.2 Land occupation and vegetation spoilage (1) Land occupation Land occupation can be regarded as the main character of the spoilage to the landform and surface coverage. According to the statistic, the area of the land occupation reaches to 36.9ha., in which the construction area is 33.68ha., and the direct influence area is 3.22ha.. Table 5-12 summarizes the information about land occupation by the project

(2) Greenbelt spoilage According to the prediction and analysis, the greenbelt being spoiled is composed of infield, wilderness and shrubbery, most of which can protect the water and soil effectively. According to disturbance and spoilage area in the prediction scope of direct influence area and investigation of land use actuality in construction area, the area of the greenbelt spoilage reaches to 18.18ha., in which the infield is 0.13ha., the wilderness is 4.38ha., and the shrubbery is 13.67ha.

37 5.4.3.3 Prediction method (1) Prediction mode 1) Soil erosion can be divided into two parts: construction disturbance erosion and waste disposal field erosion. The formula is:

Ti—Erosion period; (2) Erosion mode 1) Soil erosion mode before the project Construction takes place in the urban zone of Yibin where human activity is frequent and terrain is flat. The soil erosion mode before the project can choose the average soil erosion mode of Yibin city, which is 3631t/ (km2·a) . 2) Soil erosion mode in construction phase According to the soil erosion mode of analogous project, the soil erosion mode in different part of the construction would be: excavation slope—20000t/ (km2·a) ; backfill slope—25000t/ (km2·a) ; borrow pit—12000t/ (km2·a) ; road surface—5000t/ (km2·a)

38 3) Soil erosion mode in operation phase According to the soil erosion mode of analogous project, the soil erosion mode in operation phase would be: excavation slope—3800t/ (km2·a) ; backfill slope—4200t/ (km2·a) ; borrow pit—3800t/ (km2·a) ; road surface—5000t/ (km2·a) (3) Annual erosion quantity of waste disposal field The waste disposal field proposed located in the bottomland near the bank of Line A. According to the annual erosion quantity of the similar condition, the quantity of the construction phase would be 0.1, that of the operation phase would be 0.04, and that of the following 2 year would be 0.02 and 0.01. 5.4.3.4 Prediction of soil erosion According to the method, period, area and coefficients analyzed above, the soil erosion of the construction area and waste disposal field during construction phase and operation phase can be work out. (1) Construction disturbance erosion According to the prediction scope, erosion mode and the erosion period, the prediction result for soil erosion during construction phase is shown in the following table.

(2) Waste disposal field erosion The soil discarded reach to 547905 m3, most of which is the mixture of soil and rock with the consistency of 1.5t/m3. The designed capability of the waste disposal area is 15010m3. The result of the prediction against soil erosion at spoil waste disposal field is summarized in Table 5-14 below:

Other part of the soil discarded will be utilized in the project of Zhongba embankment. Because the utilize form and land occupation of this part of soil can not be confirm, the erosion prediction of which can be left out of account. The related prediction and protection of the soil erosion can be disposed in the embankment project. (3) Soil erosion in direct influence area The soil erosion in direct influence area includes the collapse of the slope during the excavation and the spoilage of the vegetation by human, both of which will depress the function of water and soil reservation. Because it is hard to ascertain the impact mode and the impact degree and area are limited, the prediction would not be concerned in this report. 5.4.3.5 Conclusion of soil erosion According to the prediction of the soil erosion the following conclusion can be drawn: (1) Soil erosion in construction area reach to 14,110t during the construction phase. The quantity of the main construction area (including excavation slope, backfill slope and road surface) is 9,360.2t, the waste disposal field is 4,419.8t and the borrow pit is 330t. The soil erosion before construction is 827.9t/a. The main construction area and the waste disposal field are the protection emphasis of proposed project during construction phase. The main construction areas include excavation slope, backfill slope and road surface, most of which are long distance and dispersive. Temporary defend measure should be take effectively against these parts. The percentage of soil erosion in waste disposal field reaches to 31.32% of the total, and it should set drain, bar and temporary mantle to reduce the soil erosion at the site where the erosion is concentrated comparatively. (2) As the finishing of the slope protection project and the virescence project, the soil erosion would be decreased gradually. The soil erosion would be 2347.9t during the first 3 years, and would be 16.64% of that during the construction phase. After 3 years’ environment recovery, the phenomenon of soil erosion would be reduced to disappearance, and the effect of water

40 conservation would exceed than before the construction.

5.5 Community impact assessment 5.5.1 Community impact in construction phase 5.5.1.1 Social economy influence In the construction phase, great flow of material and staff members and input of project funds as well as the consuming power of the construction group will directly propel the economic development of the construction area. The majority of the laborers will be employed in the local area except the staff from the contractors, which will increase the income of the local residents and farmers. The material needed for road construction such as cement, bricks and sand will be bought in from the nearby area, which will enhance the development of the local construction material market. All these factors will create a great deal of job opportunities for the local residents and contribute to the development of local economy. On the other hand, normal commercial activities of shops on both sides of the roads will be affected by the construction. The shoppers will feel the inconvenience and the business may thus be reduced during this period. 5.5.1.2 Traffic impact In the construction phase, the project roads will be closed or partially closed. On the completely closed roads, motor vehicles will be not allowed to pass. In some cases, even bicycle traffic and pedestrian would be restricted for safety reason. On the partially closed roads, one side of the road will remain open to traffic while the other side under construction will be fully closed. While motor vehicle traffic, pedestrians, bicycle will continuously be allowed to pass, the road traffic capacity will be substantially reduced during the construction period. It will cause adverse influence to the living, outing, working, studying and the convenience of the residents. The current bus line on Line A will be temporarily re-routed. The facilities along the closed roads will also be affected. In particular, the road closure will affect the access to schools located on Road A. But the normal pass of 405 Hospital will be affected a little, because its main access is locating on other street. Because of these road closure and semi-closure, the traffic on other roads will be increased and will result in congestion and traffic jam. 5.5.1.3 Health and safety risk Health risks are primarily related to increased transient population during construction in the regions. The increased transient population could potentially bring and spread infectious diseases in the project area. The in-hygiene and un-healthy life style of the workers could

41 spread diseases such as hepatitis to local residents as well as among themselves. The safety risk is primarily in the construction phase with the local residents, particularly children who have little awareness of construction site safety in a linear construction sites with virtually no access control along the construction site. 5.5.1.4 Impacts to the liubeichi park famous scenery The main scenery scenic spot and cultural relic historical site near the proposed project are the Liubeichi Park and the Baitashan Scenic Spot and the cultural relic historical site distributes in the two parks and so on. But the scenery spots are out of the construction scope. Its southern gate is 20m far away from the road center line near A0+040. One of cultural relics inside the park is Chengxiang Temple, with 170m linear distance from the road and with their main buildings above the surface of the road at least 10m. The other scene points are above 200m from the road. So they won’t be harmed directly by construction activity. The traffic of the southern gate, air quality and acoustic environment will be affected during construction phase. Because the southern gate adjacent to the proposed road, dust and noise impact will be serious. But noise and dust impacts on main buildings of Chengxiang Temple will be reduced greatly, due to the distance between road and Temple, as well as the countercheck of walls and trees. 5.5.1.5 Impacts on the Baitashan Scenic Spot Line A will go by the foot of the Baitashan Scenic Spot . There are braes covering normal vegetation within the area 300m away from the road. Its main amusement buildings are out of this area with 50m above the surface of the road. Thus the impacts from construction noise and dust will be small. Despite the Baitashan is out of the construction scope, attention should be paid to the protection of roadside vegetation during the construction phase. 5.5.2 social impact during operation phase 5.5.2.1 The improvement of production and living conditions Line A is one of the main roads connecting the districts on the left bank of the Yangtze River and the Min River. It is still the main traffic passage for residents along the line, which was set up in 1950. There are lots of enterprises located by the road such as Yibin Tianyuan Co. Ltd, which is one of the biggest chemical material production bases in western China. Because the present road is too narrow, traffic jam usually happens, which is most inconvenient to the residents and the business enterprises. The project will improve greatly after the alteration of the road. The vehicle speed can rise from 30 km/h to 40 km/h. In addition, the sidewalk will be set at the residents. The safe condition of transportation will be improved greatly. It is good for economy development and living conditional of people. Line B is an important passage connecting the districts on the right bank of the Jinsha River. When the new road is founded with municipal utilities on water, gas, electricity, etc. as a 42 complete set, the traffic of these districts will be distributed reasonably and it will bring as many benefits as possible to the local economic development. 5.5.2.2 The improvement of city environment The environmental condition of Line A is awful at present which is miry in rainy day and too dusty in sunshine. Not only the TSP but also the noise has been at a high level which is bad for the residents living in such environment for a long time. Besides, there is no greenbelt and drainage system along the line. All of these will be improved after the construction of Line A The construction of Line B is a powerful safeguard measure for the development and environmental protection construction synchronously in Zhaochang District and Nan’an District. It is significant to reduce the environment pollution and improve sanitary condition along the Jinsha River. 5.5.2.3 Impacts to the Baitashan Scenic Spot and the Liubeichi Park The air and acoustic environment inside the Liubeichi Park will meet the national stands except that near the southern gate. After the construction, the external traffic of the park will become smooth. It will be good for the improvement of environment of the park in a long tern. The amusement points in the Baitashan Scenic Spot will hardly be affected during the operation phase.

5.6 Solid waste impact assessment 5.6.1 Solid waste impact in construction phase The solid waste generated in construction period includes household rubbish and construction waste such as earthwork, silts, waste concrete and so on. The average number of workers needed per day is estimated to be 600, and in the peak construction period, the figure will reach to 900. If each worker produces rubbish 0.5kg per day, the amount will be 0.45t per day at the peak construction period, which is small. All household rubbish produced by the operators will be sent to dedicated municipal landfills for final disposal. At present, the treating capability of household rubbish treatment plant running in Yinbin is 600t/d, which can meet the actual requirements for the rubbish quantity. According to information offered by the designer, about 548,000 m3 earthwork and stonework will be produced from the construction of the road and the retaining wall. It will occupy valuable land, cause pollution to the environment, and impact on the landscape, if these waste are dumped in random. Contractors will be requested to transfer the solid waste to dedicated landfill sites and make sure that the urban construction waste disposal site will be available for construction and demolition waste.

43 5.6.2 Solid waste impact in operation phase During the operation phase, there will be less rubbish generated by drivers, passengers, pedestrians or residents along the line, which should be collected and sent to municipal landfills for final disposal in time.

5.7 Risk assessment

Another environmental impact during operation phase is the risk impact caused by accident on the river side road. It mainly comes from the leaking of the dangerous substance during the accident, such as the flammable, explosive, eroding and poisonous substance. The risk of the proposed project is analyzed as follows. The Line B is a new road to be built. Its main function is urban traffic, and no dangerous substances transportation to be planed. So there hardly exists the risk of dangerous substances transportation There is no gas station along LineA, and there will be no planned gas station in the future. The Tianyuan Co., Ltd., lies in the end of Line A, posses two railway private siding for its industry material and products transportation. It has planned to build new production base in Jiang’an county, Luzhou city, and the existing factory zone will not be expanded. So its transportation quantity on the proposed road will not be increased in the future. Additionally, according to the city plan, there will be Line A and Guandoushan Tunnel which connects Jiucheng, Jiuzhou and Baisha industry park. At present, the preliminary design for Guandoushan Tunnel has finished. The tunnel will be the main way for the material transportation of Tianyuan Co., Ltd.. The Line A of the proposed road will be the urban traffic road between the districts, and there is no necessity for the dangerous goods transportation. In fact, due to the strict management and pre-control measures, no water pollution incident, caused by traffic accidents of dangerous goods, has occurred for more than thirty years. In summary, there is no intention and plan for the dangerous goods transportation on the proposed Line A, and the risk rate of the river water pollution incident, caused by the dangerous substances leaking, is minima. At the same time, after the road is built, because of the curve cut-off and road surface widening, the traffic condition is to be improved largely, and the risk rate of the traffic accident will be decreased further. Considering the importance of the nearby rivers, much control measures for the traffic accident risks should still be taken.

44 6 Demolition and Resettlement

6.1 Land acquisition

The total area of land acquisition is 26.70 ha, in which 22.42ha is state owned land and will be provided by transfer. The acquisition from the collective owned land is 4.28ha, in which1.29ha for woodland (30.12% of the total land acquisition). Details of land acquisition in the project are shown in Table 6-1.

The floor space of urban house demolition is 62574.48m2 in the project, while the usable floor space of that is 32322.84m2. Among the urban demolition houses, 1762.81m2 belongs to the houses against rules. Most of the demolition is on the section A and with brick-concrete structure. The floor space of rural house demolition is 20646.07m2, mainly with brick-concrete structure, and secondly with brick-wood structure.

6.2 Affected objects

The affected objects by demolition include urban residents, rural residents, shops, enterprises and institutions, with the total population of 7849 persons. Details see Table 6-2.

45 Table 6-2 Statistics of the affected objects by construction demolition Affected objects Line A Line B Total Household number 566 365 931 Urban residents Population 1672 1206 2878 Household number 57 40 97 Rural residents Population 197 152 349 Organization 98 15 113 Enterprise and institutions Population number 4261 177 4438 Shop number 216 18 234 Shops Population 1040 40 1080 Total affected household 623 405 1028 Total affected population 7170 1575 8745

Most of the urban affected families are 3~4-person family. 60% of the affected people concentrate in Line A. Rural influenced people are distributed in 10 rural village groups mainly. The 17~60 year-old people with capacity for labor in Line A account for 66.49% of the total. The proportion of the children and old people accounts for 25%. Retired personnel and temporary labor of the affected shops account for 33% of the total affected people. The temporary labor in the affected enterprises and institutions accounts for 45%. There is no obvious social vulnerable group of scale in the affected region. But according to investigation, there are still laid-off workers existing in 107 urban affected families and 10 urban or rural affected families having disabled people and heavy patients.

6.3 The immigrants resettlement and restoration 6.3.1 The immigrants resettlement goal (1) Avoid and reduce the non- voluntary immigration as far as possible. (2) Resettlement plan must be prepared with the principle of sustainable development in order to restore and enhance the production and the living standard of affected people. (3) Combining the long-term social development target, improve the housing condition of affected people and basic and servicing facilities. Offer more employment opportunity and better development opportunity to the affected community. 6.3.2 Resettlement policy and principles (1) The immigrant resettlement plan will be based on the land requisition and building demolishing practicality indices; and will be carried out according to the land requisition and

46 building demolishing compensation and subsidy standards. (2) The immigrant resettlement will combine with the development and construction of the region, resource development, economical development, environment protection. A feasible measure to resume and improve the living standard and production capacity will be formulated and be adjusted to local conditions, and to create necessary conditions for the immigrant self development. (3) The plan and layout will be based on the principle of “contributory to production, convenient for living”. (4) For the construction scale and standards of the giving back building construction project, the principle is the combination of Yibin city space plan and the original scale of the affected people and the original standards. (5) Comprehensive consideration, making overall plans and take all factors into consideration, to handle correctly the relationship among the state, the collectivity and individual. (6) Build first, demolish later. (7) To make sufficient compensation in time according to the reinstate price. (8) To give special attention to the poor people. 6.3.3 Resettlement measure (1) City suburb country and city resident relocation arrangement 931 urban affected families and 97 affected families will be relocated and resettled either through cash compensation in which case they can choose any new areas to live in as they wish or housing compensation in which case they will be moved to new housing repaired by the government. The affected residents can choose the different schemes according to their own will and family's real economic conditions. The new housing for resettled resistant will be planned as a whole in the city. Six pieces of construction land will be expropriated in Jiuzhhou, Baisha and the west district of Nan'an, with the area of 79495m2 56464m2 77574m2 40112m2 112100 m2and 132000 m2 respectively. The Yibin Land Resource Bureau and Housing Management Bureau will organize the construction of the new resettled areas, whose area is 149917m2, 101640m2, 112800m2, 72202 m2, 134520 m2 and 264000 m2 respectively. Among them three resettled areas have been under construction in Jiuzhhou since December, 2004. The first batch houses will be completed in December of 2005, and the second will be completed in the period from October, 2005 to October, 2006. The houses will be concrete and brick structure and be built according to the standard of economic and functional house. It will provide the corresponding basic and servicing facility in the new resettled areas, including road system, sewage treatment system, electric power,

47 telecommunication, school, hospital, store and so on. The residents moved in will accept the community management and enjoy all rights of city community inhabitant, including the right of using the servicing facility. The affected people can choose cash compensation to purchase the commercial housing, economical housing or second-hand house with the resettlement department’ assistance, if they do not satisfy with the new housing repaired by the government. (2) Social insurance All the social insurance such as endowment insurance, unemployment insurance, living allowance and the subsidiary payments of start a new undertaking shall be adopted to the rural affected residents according to “The Tentative Method of Land expropriation compensation and allocation for the Rural-Urban Migrants in Yibin City” issued by Yibin People’s Government. The basic expense of endowment insurance and unemployment insurance premium the affected people shall be paid directly to the social security management organization by the land requisition department instead of the affected people. The lowest living security system has covered the Cuiping District of Yibin City where the affected people are living in. The people who become urban resident from rural resident and are up to the mustard can enjoy the lowest insurance. (3) Different allocation methods for institutions and shops

The productive enterprise suspending production above 1 year: These enterprises have already stopped business in fact, but its enterprise house has not been processed. Cash compensation shall be adapted to them in principle, assisting with the free employment training and so on.

The productive enterprise with regular production: 20 productive enterprise affected by the project will rebuild on the Baisha Industry Garden Area.

Nonproductive Institutions: Most of these Institutions shall be paid with cash compensation and rebuilt in other areas of the city. Some of them will be resettled in the six resettlement area mentioned above.

Commercial shops: The shops affected by the project are mainly rebuilt in the new resettlement areas. Some of them shall be paid with cash compensation in which case they can choose any new areas to open again as they wish. The Project Resettlement Office will provide information service to them. (4) The close down and operation of enterprise and shops and the allocation to workers The Project Resettlement Office will provide the free employment training to the people working in the affected enterprise and shops. The workers will be provided the living allowance with certain proportion of their original wages in the transition-period, until the 48 affected enterprise and shops re-run. 6.3.4 Organization and management of resettlement The implementation of the resettlement will be led by the Project Resettlement Leader Group. The Project Resettlement Office will also be founded whose staff comes from related departments. The office is responsible for the plan making and resettlement propaganda and mobilization. Meanwhile, the office is the main complaint channel for immigrants. The office must collect the opinions promptly and fully, and reflects them to the higher authority on time. It must also feedback the solving result. At the same time, the related community and the village group will be responsible for the detailed implementation of resettlement such as offering help to the hardship family, managing and paying the compensation cash, reporting the immigration’s opinion and progress of resettlement to the higher authority department. Moreover, the Yibin People’s Government entrusts the Foreign Capital Introduction and Use Research Institute of Southwest Jiaotong University as the independent monitor and assessment organization for this project. It will provide technical help to The Project Resettlement Office, supervise the resettlement action plan and provide the monitor appraisal report to the owner and the World Bank.

6.4 Environmental impact analysis 6.4.1 Impacts of housing conditions The housing conditions of the residents are mixed. Most of houses to demolish are concrete and brick structure while some are brick and wood structure, especially in the country. Some of the residents’ living conditions are poor. These are the very old housing, extremely crowded, with virtually few municipal services. All the residents will be relocated resettled either through cash compensation in which case they can choose any new areas to live in as they wish or housing compensation in which case they will be moved to new housing repaired by the government. As described above, the new housing for resettled resistant is typically multi-stories buildings with modern design which includes tap water, in apartment washroom and other convenience. Furthermore, the new areas located in much open space, with well designed landscape, quieter environment and fresher air. Such relocations represent a significant improvement of living conditions and quality of life for many of the residents, for the rural residents specially. Moreover, the new resettled areas are not far away from original areas within 2~0.5km space, so that the social culture characterized of the residents won’t be impacted due to resettlement. However, people still have to try to get use to the new environment and the new neighborhood. And the moving and relocation itself will be interruption of daily life and may cause inconvenience to the residents. These adverse impacts will occur during the project.

49 The project owner is prepared to handle it through regular consultation, providing necessary support to those who need helps and to accommodate the demands to the extent allowed by the resettlement polices and procedures. On the other side, the housing and land market is developing fast in Yibin. It is capable to offer the residents who accept cash compensation with sufficient commercial housing, economical housing or second-hand house. The housing conditions will be better than the level now. 6.4.2 Impacts of job and economic income The income of resettled residents will increase in common. However, because of their poor cultural level and skill, the rural residents may be not accommodated to the new working environment and possibly lose the job again. Otherwise, as the consumption level is higher, specially adding the realty management rate, the net income of residents moved in won’t increase a lot. Different allocation method will be taken to businesses and institutions according to the situation themselves as described above. The economic impacts for them are showing respectively as follow: The productive enterprise on the Line A will rebuild on the Baisha industry garden area, which is a rising open economic zone in Yibin city, located near the end of Line A, according to the city plan. The enterprise moved in will acquire better development conditions. It is in favor of the spread for circular economy mode as the productive enterprises come together. Consequently, the quantity and costs of the waste processing for individual enterprise will reduce. It is not only good for the development of enterprise itself, but also for the diminution of environmental pollution all over the city. For the unproductive enterprise and shops moved in the new resettled areas, their business won’t be affected much for the following reasons: One is the social culture characterized is as the same as before owning to the proximity between the new areas are to the original. The other is the resettled condition will be similar to the former. For other enterprises and shops who accept cash compensation, they can advance their techniques or facility, and optimize the composing of production or goods with the compensation. On the other hand, service equipment for commerce, which has been established with the development of housing and land market in Yibin City will provide multiplicate choice for them. However, the business will be affected when the shops open again on the strange land because of losing old clients and the change of craft brothers. In early days of resettlement, enterprise’s normal production will be affected due to the address changing, and the adventitious clerks may feel inconvenient at the same time. As a whole, so long as the resettlement work is well carried out, the construction of this project will not cause the great adverse impacts to the normal production and business of these

50 enterprises or shops. 6.4.3 Environmental impacts for the new resettled areas It will provide the corresponding basic and servicing facility in the new resettled areas, including road system, sewage treatment system, electric power, telecommunication, school, hospital, store and so on. The residents moved in will accept the community management and enjoy all rights of city community inhabitant, including the right of using the servicing facility. The living sewage and household rubbish produced by the residents will go into the corresponding treatment systems in Yibin city, which won’t pollute the environment of the new resettled areas. But when the new housings for resettled residents are building, the surface vegetation and soil will be demolished, so protection measures will be taken to reduce the soil erosion.

51 7 Environmental Mitigation Measures

7.1 Mitigation to water environmental impact 7.1.1 Construction phase (1) Construction of the retaining wall should progress in the dry season and forbid in flood season. Furthermore, avoid construction in rainy day. (2) Construction bound of the retaining wall should be restricted strictly, and prevent the soil from falling into the rivers. (3) Choose the advanced machinery in order to decrease the oil leak. The maintenance of the machinery would be supported by the applicable department in Yibin city, and there is no need to set supporting facilities in construction site which would cause oily sewage. (4) This construction located in the urban zone where the sewage system is completed. It is suggested to put the domestic sewage during construction into the city sewage system, strictly prohibit to be discharged into the rivers. (5) It is forbidden to place oil, lacquer and chemical on the river side. Furthermore, those materials should be covered and watched, preventing any spills or overflow from entering into the rivers with the rainwater. 7.1.2 Operation phase (1) Strictly implement the environment risk mitigation measures in section 7.7, prevent the surface water from the destruction of danger. (2) Improve the transportation quality and set signs in the curve, slope and crossroad in order to enhance the security consciousness and decrease the potential accident. (3) Enhance the management of the road sanitation and prevent road surface run-off from polluting the river. (4) Local government should enhance the construction of the WWTP, ensure the sewage collected by trunk sewer can be disposed in time during operation phase.

52 7.2 Mitigation measures of air quality impact 7.2.1 Construction phase (1) Set stabilized gravel blending stations as less as possible. The blending station should be at least 300m leeward the sensitive spots. The operators should be protected with goggle and respirator. (2) The asphalt mixing should be isolated and progress in plant, the mixing station must be set leeward the sensitive spots in order to mitigate the impact on air quality. (3) Construction sites along the road should be fenced with metallic sheets to decrease the impact of dust. The height of the fencing should not be less than 2 m. (4) Special staff should be assigned to sprinkle water in the dry day to mitigate the dust pollution at construction sites. The sprinkling frequency depends on the weather. In general, it progress from 7: 00 to 8: 00 in the morning, 12: 00 to 13: 00 at noon, and 17: 30 to 18: 30 in the evening. (5) Enhance traffic management and keep traffic smooth. Dusty material should be sealed in cans of bags. The soil, cement and calcareousness should be covered with tarpaulin during transportation, forbidding over loading. Choose the machinery and conveyance which meet the national sanitation standard to ensure the exhaust gas of which meets the correlative standards. Keep the vehicle clean and prevent the pollution of dirt. (6) The transportation route of construction should be determined by the environmental protection bureau together with the traffic management department. The route should avoid urban centers and sensitive spots as possible. The unit and individual for transportation must strictly follow the established routes plan. (7) Special environmental protection and management staffs should be assigned for each borrow pit and waste disposal field, directing and controlling the activities such as disposal, transportation and storage of soil, solid waste and construction refuse, and clear of the waste on road and the mud on tires. 7.2.2 Operation phase (1) All vehicles and the traffic management department should perform the rules in the tenth five-year plan of environment protection in Yibin city. According to the plan, a series of control measures will be taken by the government which focus on motor vehicle emissions control and reduce the total exhaust emission before 2005, which including: Stop the use of leaded gas in limited time, and adopt compression natural gas instead in the city bus and the taxi. Enhance the monitoring and management of vehicle exhaust emission.

53 Measures such as charge for the exhaust gas, set time limit and local examine to ensure the exhaust gas meet the national standard. The vehicle don’t meet the standards will be forbidden driving on the road. (2) Combine with water conservation measures, plant trees on the road sides especially the sensitive spots in order to mitigate the pollution of dust. (3) Limit or strictly prohibit the carriages of dangerous goods running through the proposed road. If there is necessary indeed, the corresponding national rules and laws should be strictly abided. The detailed measures are described in section 7.6.

7.3 Mitigation to noise impact 7.3.1 Construction phase Noise during the construction phase is charactered as impermanency and great influence. The primary task is the implement of Noise Limits for Construction Site (GB12523-90) which limited the noise in construction site to 75 dB. All that can be achieved through positioning the machinery in reason and strengthening the construction management. (1) Strengthening the construction management and using the low noise machinery. Keep the machinery in the best condition with periodic maintenance and passing the examination before construction. (2) Optimize the construction arrangement, the construction sites such as mixing station and material deposit site are forbidden to set nearby the schools, residential area and hospitals. (3) Arrange the construction time in reason. The construction in the segment nearby the 799 kindergarten and the No.17 Junior Middle School should be arranged to the vacation. And some provisional measures should be taken such as set wooden sound insulation board when the construction is inevitable during the school time. (4) Forbid construction during 22: 00 to 6: 00 at night especially nearby the dense residential area. If it is inevitable, construction can continue with the agreement of the environmental protection department and the construction noise should be strictly controlled. Wooden sound isolation board can be set at the dense residential area and No.405 hospital if it is necessary. (5) Make it possible to insulation the construction site such as asphalt mixing station. (6) Supervision and management should be taken especially near the school, hospital and residential area. (7) Workers in construction site should be protected by crash helmet and earplug. 7.3.2 Operation phase According to the analysis, many sensitive spots exceed the limit of noise. The mitigation measures should be taken.

54 7.3.2.1 Engineering and greening measures (1) Mitigation measures 1) Planting trees According to the Specifications for Environmental impact Assessment of Highway (on trial) (JTJ005-96) , the noise can be reduced 5dB when the spots out of the sight behind the wood which is 30m width and 4.5m height. This measure adapts to the sites which have enough space to plant trees and the excess of noise is not too much. In view of the different condition of the spots, the wood planted form A4+200 to A4+760 in Line A has a width of 6m and the space between keeps 2m×2m. Planting density should be increase at the site of the 799 kindergarten, the Xinjian Village and the Jiefang Village, the space between trees should be 2m×1.5m. The wood planted from B0+040 to B0+320 in Line B has a width of 20m with the space of 2.5m×2m between, thus it can meet the acoustic requirement of the segment. The wood planted form B0+840 to B1+440 in Line B should fit the layout of the building there and the width not less than 10m with the space of 2.5m×2m between. Although the effect of greening measure above is limited, it can resolve the noise problem of the sites where the excess of noise is not too much, and it can cooperate with other measure to mitigation the noise. 2) Sound insulation glass Double deck sound insulation glass can be used when the greening measure is not effective to the sites close to the road. It is a measure with obvious effect and not depends on the condition around, and the noise can be reduced to the degree of 15 dB to 20 dB. According to the statistics, the following sensitive spots should be fixed with double deck sound insulation glass: Line A: 799 kindergarten, 5 buildings in the Xinjian Village, 3 buildings in the Jianshe Village, one building in the Jiefang Village, 4 dormitories of No.799 Plant, Electric Power Hotel and the dormitories in the gate of Tianyuan Co. Ltd.; Line B: One dormitory of the Chemical Fiber Factory, Buildings in Shangdukou Community, Residential houses nearby the railroad and the No.405 hospital. According to the statistics, the windows which reach to 2541 m2 in total area of 948 families with 4234 pieces of pane need to be replaced. The unit price of the glass is RMB800/m2, and the total investment would be RMB 2,035,000. Furthermore, 244 pieces of pane in the No. 405 hospital and the 799 kindergarten should be fixed ventilated sound insulation glass. Each

55 of the pane cost RMB 1,650, and the total investment of this part would be RMB 403,000. The total investment of all kinds of windows would reach to RMB 2,438,000. (2) Conclusion Thanks to the mitigation measure above, the noise of the sensitive spots depress obviously and meet the applicable standards. 7.3.2.2 Assistant measures (1) Strengthen the traffic management, and set passerby partition guardrail beside the driveway in the crowded segment such as nearby the south gate of Liubeichi Park, the No.799 Plant, the dormitories of Changjiang Paper Making Ltd. and Tianyuan Ltd. in Line A, and Shangdukou Community in Line B, in order to reduce noise cause by whistle and brake when passerby across the road. At the same time it insures the security. (2) It is necessary to set signs to limit speed and whistle in the noisiest segment such as 779 Plant, dormitories of Changjiang Paper Making Ltd. and dormitories of Tianyuan Ltd. in Line A, the No.405 hospital and the Shangdukou Community in Line B. After the implement of the measures, the resident can be relieved from the disturbing of the noise.

7.4 Mitigation to eco-environmental impact 7.4.1 Mitigation to soil erosion 7.4.1.1 Mitigation measures in the main engineering area (1) Protection measures should be taken at the slope before excavation. Temporary drain ditches should be set around the excavation area, along which the sedimentation ponds would be set at intervals of 100m. The sedimentation pond would be 1.2m radius and 1.5m deep. All the drain ditches and ponds would be backfilled and planted vegetation. (2) Rushing drainage should be set along the roadbed at intervals of 50m in order to prevent the slope from being eroded. (3) The excavation and backfill slope should be reinforced in time during the construction and the drainage system should be finished at the same time. (4) The construction of bridges and the retaining wall along the rivers should avoid processing in the flood season. The waste soil should be collected after removing the cofferdam and strictly prohibit from discarding at random. (5) Vegetation measures 1) Skeleton protection and retaining wall should be set along the road slope in which grass was planted to keep the soil and beautify the environment. 2) It should plant two rows of arbors at intervals of 4m and a row of shrub in between beside the road. According to Specifications for Environmental impact Assessment of Highway, the

56 variety of the trees should be changed every other 5km. Grass also should be planted on the bare ground under the trees to prevent soil erosion. It is better to choose alder, cerdar and tung for the arbors, while dogbane, wannianchun and foliole privet for the shrub, and pink reineckia, clover or cynodon dactylon for the grass. 7.4.1.2 Mitigation measures in waste disposal field (1) Overall arrangement 1) The discard soil should be deposited in the planned waste disposal field. The location of waste disposal field should not be changed without the agreement of the owner and the design department or the environmental protection department. 2) The section of the deposit should be trapezoid and the gradient of the slope would be best between 1: 1.5 and 1: 1.2. 3) The drain ditches should be set on the top of the deposit. The gradient of the top should be between 1% and 2% to avail the drainage. 4) Retaining wall should be set at the bottom of the slope to prevent the deposit from soil erosion. 5) It is better to set bottom toes and slope cover to prevent the deposit form eroding. 6) The part above the retaining wall of the deposit should be compacted and planted vegetation. (2) Engineering measures 1) Block measure In order to prevent soil from falling into the river, grouted rubble retaining wall should be built around the waste disposal field. Building the toes of the retaining walls is necessary to protect deposit form eroding. The cross section of the retaining wall is trapezoid with toes, of which the width on top is 2m and 5m in the bottom. The slope inboard the wall is vertical while the gradient outboard of the wall is 1: 0.5. The wall is 4m in height with the heel and toe which are 0.5m in width and 1.0m in depth. The whole wall sits on the base which is 1.5m thick and 120m long. For the sake of drainage and depressing the soakage line, two drainpipes should be set in the retaining wall at intervals of 3m in horizontal and 1.6m in vertical, the lower pipe is 0.6m distance to the bottom. The PVC drainpipes whose diameter is 10 cm is better to be arrange in quincunx and with the gradient of 5%. 2) Measures against erosion In order to protect the deposit form erosion, measures should be taken against the erosion of flood. Block can be used to backfill in the bottom of the deposit, with the toes are set together. According to the numeration, the erosion depth is 2.3m which is less than that of the toes with the depth of 2.5m. And therefore the toes can prevent the deposit from the erosion

57 of the flood. 3) Measures against scouring Grouted rubble block cover is used to prevent the scouring of the flood, which should be 0.3m in thickness and 0.5m overtop the flood line. 4) Drainage measures The drain ditches are set on the top of the deposit to avoid the erosion of the rain. According to the “Regulation of Techniques for Comprehensive Control of Soil Erosion”, the standard of the design of the drain ditch is base on the maximal rainfall in 24 hours every 10 years. The section of the drain ditch is trapezoid which is 0.6m width in the bottom and 0.6m in depth. The gradient of the slope is 0.5, and the inboard of the ditches are covered with the slurry-casting block in the thickness of 25 cm which is 100m long. (3) Vegetation measures Base on of engineering measures, vegetation can be planted to ensure the stabilization of the deposit. Both the slope and the top of the deposit should be planted arbor, shrub and grass. 1) Ground condition The land occupied by the waste disposal field is 0.158 ha.. It should reserve 600m3 soils which source from the stratum 30 cm on the surface nearby the deposit. The reserved soil can be covered by plastic to protect from the rain so that all the soil can be used after the deposit formed. According to the calculation the amount of the reserved soil can meet the demand of coverage for the deposit. 2) Top of the deposit After the construction, the top of the deposit should be compacted and recover with the reserved soil, the thickness of which is 30 cm. The arbor planted on the top can choose alder, poplar and so on at the intervals of 4m in row and 6m in column. The shrub can choose dogbane and dieffenbachia at the intervals of 4m in row and 3m in column. The plant above should be mixed with each other. The total 50 arbor and 100 shrub would cover an area of 0.12 ha. In order to keep the bare ground of the protection area form erosion, the grass should be planted to form an integrated zoology system. 3) Slope of the deposit The gradient of the deposit slope could be from 1: 1.5 to 1: 2 which adapts to the grownth of the grass. The deposit should be covered with the reserved soil in 20cm thick and planted the reineckia, clover or cynodon dactylon to the area of 0.06 ha. Sketch map of typical measures for water and soil conservation sees figure 15. 7.4.1.3 Mitigation to Soil Erosion in other Site (1) Before the settlement and function of the construction site, drain ditches and basins

58 should be set at the lower side of the field. The impermanency building and sclerous ground should be moved for the vegetation recovery. (2) It should avoid forming the steep slope in the excavation site and make sure the drain ditches are set before the excavation. Vegetation recovery should be taken after the excavation. 7.4.2 Protection of the national reserve of rare and special fishes (1) Strictly prohibit excavating and discarding soil in the areas of the national reserve of rare and special fish in the upper reaches of the Yangtze River. (2) Strengthen the management of the transportation of the dangerous materials and the emergency measures against the risk to prevent the danger from entering into the river. The detailed measures are described in section 7.7. (3) Strictly implement the protection measure of the aquatic environment in section 7.3, and control the potential pollution to the river during the construction phase and operation phase. Periodic inspection for the water quality should be taken by correlative department. (4) Restrict the construction and prohibit the worker from capturing the fish in the reserve and any other destructive activities. Construction must concede to the movement of rare fish if detected and immediately report to the correlative department to take necessary protection measures. (5) Plan construction activities to the minimum during the few days when black-headed gulls, a common migrating bird, make their brief stop over in the water surface of Minjiang, Jishanjiang and Yangtze rivers on their way to the north in spring and the south in the fall. 7.4.3 Other protection measures for eco-environment In order to protect the wildlife resources and prevent poaching, the notice for protection of the black-headed gull in Yibin water areas was issued jointly in 2001 by the Yibin environmental protection bureau and other departments. It prescribed that the black-headed gull can not be hunted, killed or hurt by any people or organizations. During the construction period, the notice should be abided strictly, forbid any construction unit or person destroy the wild animals.

7.5 Mitigation to social impact

(1) Temporary passageways and overhead protection walkways will be constructed ahead of the construction to provide safe and convenient access to and from the affected communities. Temporary fences should be erected to segregate the construction area from outside in order to reduce the chances of public security accidents. (2) Warning board should be prepared at the place where construction trucks pass through frequently. Reasonable material transfer line and transportation road should be selected to

59 avoid passing through dense resident area. For the sake of mitigate the impact on resident, coordinate the transportation period of time to avoid the traffic jam. (3) Part of public transport routes would be carefully re-routed for the construction period. The new routes would be as close to the existing one as possible to minimize the impacts. The public should be apprized about the routes change in time. Temporary new gates on other streets should be created for the schools impacted by the construction, and the warning signs should be set on the access. Security drumbeating should be taken to the residents especially the children. (4) Construction activities should not destroy public service facilities along the line. One billboard, indicating name of contractor, name of construction monitoring company, hot line telephone number and contact of local environment protection bureau, will be provided at each entrance of construction site. (5) It is advised that the northern gate of the Liubeichi Park can be used as the main entrance during the construction to mitigate the inconvenience for visitors. The construction information will be public ahead. (6) Construction personnel should be taken physical check-up and epidemic situation filing in advance. Protection measures such as taking preventive medicine and inoculation should be taken regularly. (7) Social security for affected people must be well done. The local government should constitute corresponding policy to ensure residents who both loss land and out of work a minimum standard of living. (8) If an archaeological chance find is uncovered, the construction activities should be halted immediately. The contractors will be requested to protect the discovery site and respond to the corresponding government. The construction must be halted without the approval of the cultural authority.

7.6 Solid waste disposal measures

(1) Restrict the construction scope of the retaining wall and the road along the rivers, forbid the actions such as dumping waste into the river. (2) Accomplish the clearing work of the construction site after the construction of the road along the rivers. (3) Set rubbish bins in the living area, and transported to the municipal refuse dump periodically by special staff. (4) The disposal of the soil should strictly follow the mitigation measures of the waste disposal area in section 7.4.1.2.

60 7.7 Mitigation for environment risk 7.7.1 Construction phase (1) Dangerous combustible, explosive and poisonous materials such as paints, fuel should be attached warning label, marking its flammability, toxicity, physical and chemistry characteristics and the emergent prevention measures and so on. Special person should be assigned to keep the dangerous materials, write down the time when it is used, the person who uses it, the quantity and so on. The leader on duty should inspect regularly, and carries on specialized training to the keepers. (2) Fully understand the related meteorological, hydrological and geological data, connect with related department closely, arranges the construction time in reason, protects buildings, excavation slope and borrow pits promptly, reducing the environmental risk loss caused by the factors which cannot be predicted. (3) Strengthen the construction safety education. Construction sites such as waste disposal field, borrow pit, blending station and assembly yard should be isolated and managed by special personnel. Construction machinery should be checked and operated by special staff (4) Mitigation measures for traffic impact should be well done (Details are listed in section 7.5), to reduce the traffic accidents. 7.7.2 Operation phase Several agencies should coordinate in management and controlling of the dangerous cargo or materials transportation accidents. For example, traffic and public security will be responsible to secure the accident site and maintain social security. The transportation authority will be responsible to ensure permitting and inspection of trucks containing dangerous cargo. The environmental authority should be responsible for cleanup any contaminants released to the environment and minimize any potential damage to the receiving water and other natural habitat. Other mitigation measures include: (1) Packages and containers for dangerous articles will be fastened and sealed, on which special marks and designation plate will be stamped. And the property or notice of the cargo should be described in the instruction. Otherwise, it is not allowed to deliver from the manufacturer. (2) Relevant qualifications must be possessed when consigning dangerous articles. The consigned cargo will be in accordance with what listed on the check. When consigning dangerous cargo unlisted the catalog of the state, attached authentication certificate approved by the senior authority through examination will be submitted. (3) Strengthen the safety education to the drivers, strictly forbid drunk driving, tired driving and imperative overtaking; no smoking during the transportation of dangerous goods; far from open fire and high temperature area when stopping and forbid random stopping on

61 midway. (4) Transportation route of dangerous goods should be marked out by the traffic management department, avoiding the place with large population and other sensitive areas. Restrict or forbid to take the proposed road as the transportation route of dangerous goods. If there is necessary, national laws and regulations should be abided strictly. (5) Take the 119 and 110 as the quick inform means of the traffic incident of dangerous goods. At same time, an emergency response team for the traffic incident of dangerous goods should be established based on the existing municipal emergency service team. This team will be trained to handle the environmental emergency such as spilling of hazardous materials and equipped with appropriate materials and equipment. Emergency procedure should be established. Relevant authorities such as EPB, public health, police, etc., will be informed and coordinate with each other when environmental emergency occurs.

7.8 Effect analysis of mitigation measures Thanks to the environment protection measures, disadvantage impacts can be avoid at maximum degree the same as the latent economic loss caused by environmental impact.

It is recommended that, after the construction unit of the project was determined, hold an environmental training lecture for the construction of Yibin city Binjiang Road Encircling Project with the organization of the owner. The subjects of the trainings are the responsible personnel for project technologies and administrative staff in the construction and supervision units. Lectures will include: (1) Laws, documents and requirements of environmental protection and water and soil conservation in project construction by the State, Sichuan Province; (2) The environmental protection measures put forward in the design and environmental protection requirements during the construction period; (3) Guide of the environmental protection during the construction period. The training course will invite experts from supervision units, provincial and municipal Environmental Protection Bureaus and the principal take charge of the environmental protection design. 8.4.2 Operation phase According to the environmental management plan, the management work will be transferred to the Yibin Environmental Protection Bureau during the operation period, thus the personnel training for the proposed project will be organized and implemented by the Yibin Environmental Protection Bureau, which should be put into their routine training plan.

8.5 Estimated investment on environmental protection

This investment of environmental protection in the project includes the expense in environmental protection measure and environmental monitoring, substantive expense, and preparative expense. All the expense is calculated according to the statutes of corresponding methods and calculated standards. Substantive expense includes the expense of construction management, reconnaissance and scientific research, and taxation etc. Some explanations is as following. 1) Expense of construction management It includes the expense of construction management of engineering, environmental

73 construction inspecting and management, consultation cost, acceptance inspectation cost. The expense of construction management of engineering is 2.25 percent of the expense in environmental protection measure. The expense in environmental construction inspecting is 2.15 percent of the expense in environmental protection measure, but it can be adjusted by fact. The expense in counseling is 0.5 percent of the expense in environmental protection measure. The expense in technique economy censoring of project is 0.1 percent of the expense in environmental protection measure, which can be adjusted by fact. 2) Expense of scientific research The expense in scientific research is 0.5 percent of the expense in environmental protection measure. The expense in compiling EIA report and Water and Soil conservation report can be calculated on corresponding standard of charge. The expense in checking, researching and evaluating after the environmental protection action can be estimated by fact. 3) Other taxation It includes the expense of quality supervision of environmental protection, quota compiling management and establishing technical standards. The expense in quality supervision of environmental protection is 0.15 percent of the expense in environmental protection measure. The expense in quota compiling management is 0.09 percent of the expense in environmental protection measure. The expense in establishing technical standards is 0.5 percent of the expense in environmental protection measure. The basic preparative expense equals the product of the sum of three parts of substantive expense and the basic preparative expense rate which is 10 percent. This project invests RMB 5130.7 thousands on environmental protection which is about 1 percent of the total investment of project. Estimated investment on environmental protection is shown in Table 8-4.

75 9 Public Consultation

9.1 Purpose of public consultation

According to the ‘Management Regulations on Environmental Protection for Construction Projects’ and the technical guidelines for EIA, broad public consultations were carried out in the affected area. The principle of the public consultation is opening and fairness. It can provide basis for the environmental protection and decision making. The proposed project will bring some environmental impacts (advantageous or disadvantageous) to circumjacent area during construction period and operation period, directly affect the profit of residents around. Through the public consultation, the public may know the basic information about the project and the possible environmental impact caused by it. Also the public could give their advice, which will be help to optimize the engineering design and decrease disadvantageous environmental impact.

9.2 Survey method and content

In order to clearly know about public’s opinion on environmental impact and their satisfactory degree on the mitigation measures, the EA team carried out public consultations for twice and information disclosure for once. Various forms such as questionnaire survey, conversazione, etc. are adopted in public consultation. The summary of the public consultations is shown in Table 9-1.

Till the report is finished, EA team has not received objections from different fields. It is proved that the project has been approved by the public.

82 10 Conclusions and Recommendations

10.1 Rationality of the Project

At present, Yibin is very short of construction land, and the expansion of the urban space is in urgent need. The key of the problem is to strengthen the connection between the old urban district and the new urban districts. The proposed project can provide a base for the exploration of new urban district. The construction of the proposed project will facilitate the swift connection among the districts, and promote the ordered and smooth flow of passengers, freights and automobiles. It can activate the adjustment of urban structure through the improved urban road networks, and then provide necessary basic guarantee for the expansion of urban space and the improvement of the urban functions as well. The proposed project is also the important hinge for the switching of internal and external transportation of Yibin City, which is closely connected to other external transportation networks such as the Yibin-Nanxi Road and so forth. At the same time, taking the historical culture and the Yanze River cultural as its main design topics, the landscape will connect the city culture with the citizen’s living closely, and make the landscapes become a bright spot for the citizens to rest, recreate and sightsee. All the proposed roads of this project are from the ‘Road Network Planning of Yibin city’. The road sections are optimized roads and have been arranged according to the demand of economic development and traffic increases. It is benefit to the city's development and environmental upgrading in the urban area. Seen from the local situations, the proposed roads bypass the scenic spots and historical site such as Luibeichi Park and Baitashan scenic spot, decreasing vegetation damage and soil erosion as far as possible, and mitigating resettlement. Therefore, the line selection is rational.

10.2 Assessment on present environmental status 10.2.1 Water environment According to the water quality monitoring data, the water quality of the Jinsha River, the Min River and the Yangtze River in the Yibin section is good, except the coliform bacteria, the total nitrogen and the oil exceeds the required standard sometimes (Environmental Quality Standards for Surface Water (GB3838ü2002) ) Class . The above factors which exceed the allowed standard mainly comes from the influence of the city sewage discharge.

83 10.2.2 Ambient air quality

The main air pollutant factors discharged in Yibin are SO2, NOx and the hydrocarbon and so on. The main sources are the exhaust gas produced by industry, daily lives of public and the automobile tail-gas. According to the ambient air monitoring results, the main air quality indexes in the summer has not surpassed the Ambient Air Quality Standard

(GB3095-1996) Class , but SO2 and PM10 exceeds the required standards in winter. 10.2.3 Acoustic environmental quality The noise levels of most noise sensitive spots in the construction area exceed the standard of Environmental Noise Standard of Urban Area (GB3096-93) Class in daytime, and much more serious in nighttime. The noise levels of special sensitive spots such as school and hospital can meet Environmental Noise Standard of Urban Area (GB3096-93) Class in daytime, but still exceed in nighttime by the reason of heavy traffic and narrow roadway. 10.2.4 Eco-environment Quality Yibin City has developed extensive water and soil conservation and the ecological Environmental Protection work in recent years, established the National Natural Reserve of Rare and Special Fish in the Upper Reaches of the Yangtze River, the ecological environment quality has been remarkably improved. But looked from the overall, the protection of eco-environment and the speed of recovery still underdevelopment, the eco- environment quality is still under threaten. 10.2.5 Social Environmental Quality Yibin city is located at the junction of Sichuan, Yunnan and Guizhou Provinces. It is the transportation and trade center of this region, which has the advantage in energy, food and chemical industry and with the characteristics of wine industry. But the extractive industry is still unenlightened in Yibin City, and the industry is lack of advanced technology. The economic structure is unreasonable and it still needs large numbers of fund to get rid of the predicament in the development.

10.3 Assessment conclusion of environmental impacts 10.3.1 Assessment conclusion of environmental impacts during construction phase The environment along the road will be impacted during the construction and operation phase. The lives and studies of the residents around will be disturbed by the construction noise and dust. The favorable effect is the potential social and environment benefit after construction.

84 (1) Water Environment The pollution to the water environment mostly comes from the excavation and fill activities. The main pollutant is suspended solids (SS). According to the analysis and model prediction, the impact on the water environment caused by construction can be very limited. (2) Ambient air Dust will be a primary air contaminant during the construction phase. The sources of the dust will primarily be building demolition, materials transportation and the activities such as activities such as load and unload materials, blending and so on. The impact distance is 100 ~150m leeward the sources. (3) Acoustic environment The construction noises mainly come from the working of construction machinery and the building dismantling. According to model calculation result, at the distance of 100m to the construction site, the maximal noise can reach 70 dB (A), which is almost accord with the Noise Limits for Construction Site. (4) Eco-Environmental impact The proposed project is not in the range of the National Natural Reserve of Rare and special Fishes in the Upper Reaches of the Yangtze River. The main impact on the reserve comes from the excavation and fill activities which may pollute water quality of the reserve. According to the prediction, the impact on the reserve is little. Additionally, soil erosion may occur due to the damage to the original surface vegetation and soil. (5) Social impact In the construction phase, great flow of material and staff members and input of project funds as well as the consuming power of the construction group will directly propel the economic development of the construction area. On the other hand, in the construction phase, the project roads will be closed or partially closed. As a result, not only the normal out going or commercial activities of the residents, shops or enterprises on both sides of the construction roads, but also the traffic on other roads nearby will be affected. Health and safety risks will be brought by the workers and the construction activities. 10.3.2 Assessment conclusion of environmental impacts during operation phase (1) Ambient air The TSP concentration will be small due to the asphalt concrete road surface, and the main contaminant during operation period is NOx produced by the automobile exhaust.

85 According to the forecasted results, in the yearly mean terms and under the unfavorable cases, NOx concentration on sectionA0+000~A0+640, A1+040~A1+800, A4+640~A5+130 will exceed hourly mean concentration of national standard Class II. The exceeded range is mainly in the range of 20m from the road center line, and 20m away form the road axis, NOx concentration is below the standard value. None special sensitive spot such as hospital, school and residential areas are in the exceeded areas. On the rest parts of Line A and all of Line B, the NOx discharge concentration 10m away is below the standard value of Class II . (2) Acoustic environment According to the forecasted results, noise levels of Line A increase obviously to the extent of 7dB to 15dB in long-term. The noise on some common sensitive spots exceed the Standard of Environmental Noise of Urban Area (GB3096-93) class ,which are the dormitories of 799 Factory, Changjiang Paper Industry Co., Ltd. and Tianyuan Co., Ltd.. The noise on some special sensitive spot, such as 799 Kindergarten, exceed the Standard of Environmental Noise of Urban Area (GB3096-93) class . The noise on some sensitive spots in Line B exceeds the applicable standards, which are 405 Hospital, the dormitories of Fiber factory and Construction Committee, Shangdukou Community. One main reason is that the background noise exceeds the standard. (3) Water environment During the operation phase, the pollution mainly comes from the initial rainfall, and the main pollutants are oil, SS, COD, but the concentration is low, which will not pollute the receiving water body obviously. And the domestic sewage yielded by the residents along the line will go into the urban sewage systems, which cause little impact. (4) Social environment During the operation phase, the transportation condition will be improved, which will promote the economic development of the city. Municipal drainage pipes and landscape engineering will improve the living environment and quality of the residents. (5) Risk analysis During the operation phase, vehicles carrying dangerous materials will probably have leakage accident, which will cause adverse effect on the water, soil, vegetation and the people along the roads. However, risk transportation management will reduce such adverse impact to minimum level. (6) Analysis of resettlement It is unavoidable that there are some houses to be demolished and some people relocated. However, according to the relative compensation laws, regulations and rules, these people or units will be compensated. And according to the removing and resettling experience

86 before, the compensation houses and living standard of the resettled people or enterprises will be as good as or even better than before.

10.4 Mitigation measure for environmental impacts

The proposed project belongs to the non-pollution ecological project, no pollutants produced during its operation periods and thus there is no grass-control problem. Aiming at the impacts during construction and operation phases, environmental protection measures for water, air, acoustic, soil erosion, resettlements, traffic, risks and other impacts are put forward in EIA report. The measures mainly include controlling construction in nighttime, limiting vehicles speed; sedimentation of the foundation waste water during the bridge construction; incorporating sewage waste water into urban sewage system; sprinkling for decreasing flying dust; road maintenance and greening; bringing the organic rubbish to the rubbish disposal field of Yibin; enhancing education on the eco- environmental protection, taking plant and engineering measures to control soil erosion; greening and installing noise-isolated glass to reduce noise. The environmental management, monitoring and supervising plan are also brought forward. The plan can guarantee the measures to be put into effect, and play the mitigation or controlling function.

10.5 Conclusion

The construction duration and operation period of this project will inevitably cause a number of adverse effects, which may be mitigated or minimized by some corresponding measures. Besides, the construction of this project can improve the infrastructure and management level of traffic as well as the environment and air quality in Yibin. All in all, the implementation of this project is consistent with the principle of the combination of social, economic and environmental benefit, therefore, this project construction is feasible. Based on the analysis and forecast listed above, it can be seen that the proposed project is in accordance with the urban master plan, and is an important part of the urban traffic plan. The main adverse impacts are the noise and air impact. After corresponding measures is taken, the various adverse impact will be mitigated or decreased on some extent. Therefore, it can be concluded that there is no significant environmental factors restring the project, and the project is feasible from the view of environmental protection.

10.6 Recommendations

In order to do the environmental protection work of the project as well as possible, it is suggested that environmental protection management system be set up as soon as possible. It includes establishing specific environmental protection department, carrying on

87 environmental supervising institution, and carrying out environmental protection measures and “three simultaneity” system. Considering the requirements of construction and construction arrangement, check up and improve the environmental impact and mitigation measures further. Establish more comprehensive and systematic environmental protection measures; get done with the environmental protection work of the project, mitigate the adverse impacts as far as possible.
