Preface

Panzhihua City is an important industry base of steel vanadium, titanium and energy in China. Industrial construction is put in the first place while urban construction lags behind relatively in the past. In order to build Panzhihua City into a modernized metropolis, the urban construction process must be accelerated and the urban environment, improved. The environment improvement project which World Bank loan will be used is just to meet the demand of Panzhihua City development.

The whole project consists of riverbank slope protection, upper section of Binjiang Road, interceptor and trunk sewers, scenery project and last section of Bingren Road. The four subsections are named as environmental improvement project along the Jinsha River. The gross investment budget of the project is RMB 1220.65 millions Yuan (nearly $ 147.42 millions), and the budget of RMB 577.94 millions Yuan (nearly $ 69.80 millions) will be from the World Bank loan.

The construction of the project will improve the urban environment infstructure of Panzhihua City and improve the landscape along the Jinsha River. It can also provide an essential basis for continued urban development and living environment, and lay a solid foundation for turning Panzhihua into a beautiful city. At the same time, it can improve traffic condition of the city, irmpove the urban zoning, and broaden the developmental space and development potential of the city.

This project is in accordance with the national policies. Based on the relevant laws, rules, policies and the specifications on environmental protection by China National Environment Protection Agency (NEPA) and the stipulations in the Guideline of Environmental Assessment by the World Bank, the environment impact assessment of the project should be carried out. For this reason, Chengdu 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 Panzhihua Urban Construction Investment Management Co., Ltd. Based on the analysis of project design files, the EA team carried out an project site survey and collected materials related to the project. According to "Technology Guideline of Environmental Impact Assessment", "Environmental Impact Assessment Specifications of Highway Construction Project" and the World Bank related environment assessment business policies, the project environmental impact pre-assessment report was completed in May, 2005, and submitted to the World Bank delegation for pre-assessment of the project. At the same time, "Environmental Impact Assessment Outline of the Environment Improvement Project in Panzhihua City" was completed. At the request of Sichuan Environment Protection Bureau (SEPB), Sichuan Environmental Engineering Evaluation Center hosted the technical appraisal meeting of the outline on May 18, 2005 in Chengdu. According to opinions and suggestions of the attending representatives and experts, the final edition of the outline was completed in August 2005..

According to the document issued by SEPB and opinions and requirements of the World Bank, the EA team carried out several rounds of site survey and investigation, and entrusted Panzhihua Environment Monitoring Station to monitor the acoustic environment and substrate sludge in the The Jinsha River River supplementally. On the basis of these

work, "Environmental Impact Assessment Report of Environment Improvement Project in Panzhihua City" was prepared in October 2005 to submit to the World Bank for project appraisement, and to SEPB for examination.

Overview

Origin of the Assessment

The Environment Improvement in Panzhihua City is a sub-project of Sichuan Urban Developmente Project (SUDP), to be supported by a World Bank (WB) loan. It consists of environmental improvement along the Jinsha River and the construction of the Bingren Road last section. World Bank project task team inspected Panzhihua City on November 20th~28th, 2003, May 31th~June 5th, 2004 and October 18th~27th, 2004, respectively, and subsequently determined the contents of the urban environment improvement project. Sichuan Provincial Development and Reform Commission approved the project in October, 2004. The project will improve the environmental infrastructure of Panzhihua City, improve the living and transportation conditions and provide new space for urban development of the city.

According to the reqirements of the environmental protection laws, regulations, policies and the specifications on environmental protection of China and requirements of the relevant World Bank operational policies, an environment impact assessment (EIA) for the project should be carried out. CHIDI was commissioned by Panzhihua Urban Construction Investment Management Co., Ltd. to undertake the EIA of the proposed project

Background of the Project

Panzhihua Urban Planning

Urban Development Plan

According to the Master Plan of Panzhihua City (1997-2020), the objective of Panzhihua City development is to build a modern city with an industry base related to natural resources in western China, a regional center in the boundary area of Sichuan and Yunnan Province and a garden city with mountain, river and the southern subtropical scene. Three zones are planned for City development, which are the urban centre, urban area and city area. The urban area is aobut 65 km2, from Geliping to the west, Jinjiang Town to the southeast, the foot of Dahei Mountain to the north, and Renhe Town to the south. The city area includes urban district, Miyi and Yanbian Counties with a total of about 7440.4 km2.

The urban center Panzhihua City consists of East District, West District and Central District. The Central District consists of Bingcaogang, Duren, Nongnongping and Panmi sub-district. The urban centre locates in Bingcaogang which has political, economical, cultural, technological, commercial and financial function. The area of the urban centre is about 40 km2 and the population is about 400 to 420 thousand. The west district consists of Geliping, Hemenkou and Taojiadu sub-district. The major functions of the district are energy generation, building material and timber machining. The area is 1517 km2 and the population is 180~200 thousand. The east district’s functions are railway transportation pivots, material distributing and titanic industry. The planned area of this district is 9 10 km2, with population of 30 to 50 thousand.

According to the urban planning, the area of the control land will be within 60 km2 and the population will reach 1133 thousand by 2010. The GDP will reach 289 hundred million, about twice as the data in 2000. The per capita GDP will be 25.8 thousand. The ratio of primary, secondary and tertiary domain in civil economic is 3:57:40. The industrial structure will optimize constantly.

The proposed project accords with the overall plan of Panzhihua City. It is beneficial for environment and road network improvement, industrial structure adjustment, space distribution optimization and economic development. It is also helpful for improving ecological environment and river scenery along the Jinsha River.

Road Traffic Plan

Urban road system consists of express road, primary trunk road, secondary trunk road and sideways. The urban centre will be the core of the road network where roads stretch out along the south and north banks of the Jinsha River and Renhe Stream, forming a network. Roads in the urban area were designed and built according to the actual landform. By 2020 the trunk road in urban centre will reach the length of 465 km and the density of the network will be 7.65 km/km2. The ratio of the land used for road and city square will be 12.54%, the area of per capita land will be 11.58 m2.

The public traffic will be the first choice in urban road system. Network structure will be optimized, and vehicle component will be moderated. By 2020, the total length of the public transportation network would be 219.1 km with the density of the network of 3.65 km/km2.

According to the ‘urban traffic plan of panzhihua city for 2000~2020’, the road G108, S310, S216 will rebuild to second level road. A series second and third level county road will be constructed to communicate to the outside. Centre road plan emphasizes on the rebuilding of Bingren Line, Binjiang Road, Yanze Road, Yanhong Road, Honglan Road, Bingqing Road, Taoshi Line (from 06 bridge to Geliping) and Panmi Line to adapt the development of the Bingcaogang district, the area along the Jinsha River, Yanbian new town and Ertan landscape spot. The traffic road plan will also serve for the Panzhihua Steal factory, Mining Bureau, and Panzhihua Mine Factory. More investment will be used on rebuilding the Jinwu Road, Zonglong Line and Dujin line which form a chain line to adapt the development of the Jinjiang industrial developing district and bring the future economic developing hotspot into the new traffic network.

The project is a component of road traffic plan. The front section of Binjiang Road will connect Jiangnansilu Roads with the constructed Binjiang Road to form a double way in the downtown area. The last section of the Bingren Road is a extension of the front section. This road will connect the future urban centre with the Renhe district. The construction of the last section will strengthen the density of the urban road network and alleciate the pressure which brought by the traffic in urban centre. It will also make positive effect on developing the new urban. It is therefore that the road construction suit for the road traffic plan.

The plan of urban water source, water supply and drainage project

According to the plan, the water source of Panzhihua city is surface water which comes

from the Jinsha River and the The Yalong River River except for some unit individually. By 2010, the scale of the supply water in urban centre will reach 226 thousand m3/d. Water supply and sewage capacity in urban area of Panzhihua City is listed below.

Industry waste water should be treated to the required effluent quality before discharge, and the total capacity of the sewage will be controlled. The principle of disposal for urban waste water is to protect the drink water in the near future, then protects the quality of river in the far future. Nine sewage WWTPs will be constructed, such as Geliping, Tanjiadu, Hemenkou-Qingxiangping, Duren, Bingcaogang, Nongnongping, Panmi, Jinjiang and Renhe. The scale of the Bingcaogang sewage WWTP which has already been built is 30 thousand m3/d, while Renhe sewage WWTP, which is under construction, is 20 thousand m3/d.

The interceptor and trunk sewers of this project consists of the first and second grade interceptor and trunk sewers in Qingxiangping sewage WWTP, Wushisi~ Bingcaogang interceptor and trunk sewers and some sub-trunk pipe. To suit for the interceptor and trunk sewers construction, Qingxiangping sewage WWTP is planned to be constructed at the same time (details see Appendix 5).

Background and Necessity of the Construction

Background and Necessity of the environmental improvement project along Jinsha River

(1) Background of the construction

1) The sustainable development situation of the city

The urban sustainable development level of Panzhihua is not high; the SD of Panzhihua is only 0.42 in the estimation by Beijing University. The river bank protection of the project is benificial for improving the sustainable level of the city. In terms of system coordination, ecological environment treatment intensity will be increased, the ratio between pollution treatment fund and GDP will be raised, and the ratio of pollutant discharge with the growth rates of GDP will be reduced. The correlation of economy and social development will be added by improving the contribution rate of science and technology progress and the employment rate. In terms of system development level, the quality of ecological system will be improved through upgrading the atmospheric and water body quality indicators.

2) The requirement of urban economic and social development

Although the history of Panzhihua City is short, it is well known both home and abroad. In 2002 the GDP per capita was 13,200 yuan, which ranks No. 2 in Sichuan Province. However the city’s public infrastructure is not suitable for its present situation, the city is not beautiful enough, and human habitat environment is far from perfect. All those affected the stability of employee team and the development of economy to a certain degree.

This project can beautify the city, improve the urban scene and transportation, and help to enhance public’s determination to “love Panzhihua and build Panzhihua”. It is instrumental to stabilize the employee team and play a proactive role in the talent introduction and investment promotion, indirectly facilitate the economic and social development of this city.

3) The demand for the construction of a ‘city with mountainous and waterside garden’

After the former Premier Zhu Rongji advocated for “to build Panzhihua into a city with mountainous and waterside garden”, in order to implement this instruction, “Master Plan for Panzhihua, the City with Mountainous sand Waterside Garden” was drafted. This project is the implementation of this master plan, and is one of the important steps in the realization of the master plan. The completion of the project shall accelerate the pace for constructing Panzhihua into a city with mountainous and riverside garden, has important meaning to the urbanization and modernization of Panzhihua city.

(2) Necessity of the construction

1) Need for ecological environment improvement and pollution control

Along the bank of Jinsha River, more than 40 million tons metallurgical dreg, gangue, coal slag and building rubbish have been piled up, which the west slag field of Panzhihua Iron and Steel Group, the slag field of Panzhihua Coal Group and the spoil ground of Panzhihua Cold-rolled Factory are the large-scale ones.

The West Slag Field of Panzhihua Iron and Steel Group is more than 100m high and more than 1km in length, the area occupation of which is more than 40ha.

The water quality of Jinsha River along Panzhihua city is not good as expected because of the drainaging waste and losting of water and soil. Moderating the protection facility, the project is propitious to the spoil dreg’s stabilization and pollution and water & soil lost

control.

2) Need for city beautification and living environment improvement

The present status of the river bank is in a mess. The land type on Jinsha River bank is mainly the shrubs and weeds, protectection sill of the building waste, naked rock beach and patched farmland.

The standard of the city view and environmental quality is higher and higher according to the demand of resident. The desirability to improve the living environment is being more and more intensity.

Such a mess bank does not suitable for the modernized cityscape obviously. Renovating the Jinsha riverside is a demand for turning Panzhihua into a modernized city as a garden with beautiful mountains and rivers.

High qualitative urban extent is a mainly guideline in modernization. Such mess river bank is not suitable for the above demands. From this point of view, it should improve the environment of the river bank.

Sichuan Province, Yunan Province and Tibet Autonomous Region have decided to construct the ‘The Great Shangri-La international ecological tour district’. Panzhihua City situated at the siteseeing line, and was famous for its ancient sago cycas forest which is the biggest, most peculiar and largest in number. The age of the forest is 2.7 hundred million years (same age as dinosaur). The construction of the project can improve the environmental quality and make the city to match the brand of international tour district.

Background and Necessity of the last section of Bingren Road

(1) Background for the last section of Bingren Line

1) Liquidize the land assets, speed up the pace for modernization

The construction of last section of Bingren Line can not only bring along the land development for the area of 6.5 km2 at Ganbatang, etc, but also facilitate the transformation of rural population to urban population while building the new district, and upgrade the urbanization level.

In the indicator system for the city to basically realize modernization, the completed investment in the construction of various infrastructures in 2002 accounted for only 9% of the GDP of that year. There is a considerable gap between the requirement of no less than 15% of GDP invested in infrastructure. The construction of this project and the new district development shall greatly minimize this gap, and speed up the pace for urban modernization.

2) Create conditions for development of tertiary industry and improvement of economic structure

Panzhihua is a city of heavy industry. In 2002 the ratio of three industries are 6.2:68.5:25.3. This was seriously against the basic requirement of modern economic structure in which tertiary industry’s percentage shall be larger than that of secondary industry. The growth of GDP must be “at the price of resource squandering and damage to environment which result in the situation of ‘growth without development’” (conclusion of the joint study in 1998 conducted by Beijing University and Municipal Planning Commission of the city). Panzhihua city is of the land form of mountainous river valley. 25% of the land for

development for the new district is located at slope up to 25 degree. However the terrain from Renhe Township to Zongfa is relatively plain, where water, electricity and road access are available. The development cost for this district is relatively lower, which shall facilitate the development of real estate, heighten the development of tertiary industry and investment promotion.

(2) Necessity of the construction

1) Need for road network densification and Renhe District development

Renhe District has changed into an important part of urban centre from suburb. However, there is only Duren Road which connecting Bingcaogang and Renhe by way of Dadukou. It is expected that the traffic volume of the road would be up to the 20,000 cars/day in 2005 and 28,000 cars/day in 2010. Considering rapidly development of Renhe District, it is necessary to develop Bingren Road last section and form the traffic circle connecting the two important district of Bingcaogang and Duren. It will not only increase the density of the urban road network of Panzhihua, but strengthen the connection of districts as well.

2) Need for the safety of Bingcaogang District and Airport Road

Bingcaogang District to be constructed soon lies by Bingren Road. The road to the airport which has just been put into operation connects with the middle section of Bingren Road. At present, there is only the first section of Bingren Road which connects Bingcaogang district and airport with Bingcaogang& district. If the last section of Bingren Road can’t be opened, Bingcaogang district and airport will be disconnected with other districts of Panzhihua when landslip, earthquake or serious traffic accident happen. It is imperative to open Bingren Road and increase more traffic entrances and exits.

Being an important part of the urban centre, more and more enterprises and public institutions will move into Bingcaogang district, while a large number of their staff's relatives and children work and study in Bingcaogang & district. As the commercial center of the whole city is mainly in Bingcaogang district, the internal and external connection is extremely frequent. It can be expected that Bingcaogang district will be crowded closely with private cars and result in serious traffic jams at the joint section of Bingren Road and Jiangnan’erlu Road. If Bingren Road opens smoothly, an entrance will increase and some traffic will be shunt, thus the traffic jams on the section can be decreased and the traffic safety will be ensured greatly.

3) Need for urban development and construction

The land resource is very tense in the urban area of Panzhihua. Through the construction of the last section of Bingren Road, 6.5 km2 can be explored for urban construction. It is especially valuable for Panzhihua, the hilly city, where more than 92% area is upland.

The industrial structure of Panzhihua is unreasonable. The secondary industry is too big while the tertiary industry is too small, being the last one among the 10 national largest steel cities and 20 Provincial cities of Sichuan. To improve the industrial structure and develop new space for the tertiary industry, the construction of the last section of Bingren Road is the most effective way.

The population distribution of Panzhihua is not balance. By the end of 2003, the total urban population is 520,000 and the density is 12,400 persons per capita square kilometer. The population density of the urban center is much higher than the average. Through the construction of the last section of Bingren Road and development new urban area, some people can move out from centre district and much population can transfer from contaminated area to the new urban area.

4) Need for collecting fund and paying off loans

Most of the lands along the Bingren Road are wasteland. In the construction of Bingcaogang district, the price of the wasteland increases from RMB 450,000 Yuan per capita ha. (RMB 45 Yuan per capita m2) to RMB 2 million Yuan per capita ha. (RMB 200 Yuan per capita m2). The value of the wasteland would rise to RMB 1.55 million Yuan per capita ha..6.5 km2 lands can be developed when the last section of Bingren Road is completed, thus it can take back the fund of RMB 1 billion Yuan.

With the construction of the road, the price of the land on both sides will raise up. Bingren Road is about 11.28 km long except the tunnel, the utilized land on both sides of the road is assumed to be 30 m wide and the appreciated value of the land is RMB 900 Yuan; RMB 600million Yuan can take back.

The incomes mentioned above can repay all the loans of the project (including the project of Jinsha riverside environment improvement).

Brief introduction to main part project

The main part of the project consists of riverbank slope protection, upper section of Binjiang Road, interceptor and trunk sewers, scenery project and last section of Bingren Road. The riverbank slope protection, upper section of Binjiang Road, interceptor and trunk sewers and scenery project are named as environmental improvement project along Jinsha River.

Riverbank slope protection

Type and schemes

In view of the circumstance of the bank along the river, there are three schemes for the slope protection.

(1) Incline retaining wall

This scheme is applicable to the waste disposal area located in the left bank downstream of the Xinzhuang Bridge from 0+550 to 1+330. This segment lies in the coulee of river where is too narrow to progress the excavation work. Considering the risk of landslide and the investment, the slope protection for this part below the flood line every 20 years should be designed as the masonry retaining wall, and which between the flood line every 20 years and that of every 50 years should be designed as the geogrid.

(2) Gravitation retaining wall

There are three waste disposal areas respectively located in the right bank between Xinzhuang Bridge and Dukou Bridge from 3+450 to 4+600, the left bank between Dukou Bridge and Midi Bridge from 4+700 to 5+750, and the left bank downstream of the Luoguo Bridge from 0+000 to 0+325.26. The gravitation retaining wall should be the best choice from the view of economy and technology.

(3) Skeleton slope protection

There are four skeleton slope protection sites respectively located in the right bank between Xinzhuang Bridge and Dukou Bridge from +280.13 to 6+971.76, the right bank of the waste disposal area of Bingcaogang Sewage WWTP from 2+455.58 to 2+854.39, the right bank from Midi Bridge to Luoguo Bridge, and the right bank from Luoguo Bridge to Shuangjiangkou Bridge. The main objective to construct the slope protection is glorifying the bank along the river. The rhombic skeleton should be the most suitable type for the skeleton slope protection in the view of economy and technology.

The statistics of the types of slope protection is shown in the following table.

Construction planning

Construction Sites Planning

The project lies in the downtown area and suburb of Panzhihua City, the land near the construction project is fully utilized. But it is easy to rent the ajacent residence house. Therefore, the residence houses are rent for construction campus. This can reduce the land use and land surface destroy, and can reduce environmental impact as a result.

According to the construction planning, the asphalt and concrete mixing plant is set on the flat ground which is close to the right exit of the Basiqing tunnel. This site is far from the downtown area, and is convinient for transportation.

Construction material planning

According to the feasibility report of the project, the sand and aggregate rock used in the project will make full use of local materials. The distribution of the primary choice result are listed as follows.

(1) Sand materials fields�

The sand materials which used for slope protection mainly come from sand of the flood plain and the first- and second- grade terrace near the river. The main fields include Jinjiang ~Chumuchang, Sanduizi, Outlet of the Yalong River, Lanyuanzi, Midi, Makan, Bingcaogang, outlet of Ren Stream, shenli village, Baoding ore, Huashan ore, outlet of Baguan river and Geliping.

The materials used for building are medium and coarse sand which come from mouth of Bala River, Shaba, Lanyuanzi, Renhe and Baguan River.

(2)�Stone material fields�

The materials used for slop protection can adopt the mixture of pebble and flaky stone. The extract area for flaky stone distribute at Yutang township of Jinjiang town, Wudaohe stone field, riverside along 501 power plant, backside of Qingxiangping mountain, Xinzhuang, Baoding, Hemenkou ~ Geliping.

(3)�Filling material field�

Analysis of the project

Accordance analysis of the project with correlative plan

Accordance of the project with urban master plan

According to the ‘Urban Master Plan for Panzhihua City(1997-2020(2015))’, the goals for the city development are: proper redistribution, multiplicity function, modernized facility, clean and beautiful environment and legal management. Panzhihua City will be developed into a modernized metropols at the end of 2010.

After the environment improvement project along the Jinsha River is completed, several ecological green space and water-contact platforms will be bulit. That will effectively beautify the city, improve the living condition and lift urban landscape. The construction has important meaning for the control of soil erosion and the Yangtze River environment protection. The construction for the last section of Bingren Road can increase the density of urban traffic network, develop new urban area, extend urban developing space, promote the adjustment of industrial structure, release the population pressure in urban centre, improve the working and living environment, improve the ecological environment and promote the coordinated development for economic, society and environment.

Therefore, the construction is in accordance with the master plan. It is the specific execution for plan and has important meaning for the urbanization and modernization.

Accordance of the project with Road Network Plan of�Panzhihua city

The Urban road system consists of express way, primary trunk road, secondary trunk road and sideways. The urban centre will be the core of the road network where roads stretch out along the south and north banks of the Jinsha River and the Renhe Stream where forms a network. Roads in the urban area were designed and built according to the actual landform. By 2020 the trunk road in urban centre will be 465km and the density of the network will be 7.65km/km2. The ratio of the land used for road and city square will be 12.54%, the area of per capita land will be 11.58m2.

Road plan for urban area emphasize on the rebuilding of Bingren Line, Binjiang Road, Yanze Road, Yanhong Road, Honglan Road, Bingqing Road, Taoshi Line ( from 06 bridge to Geliping) and Panmi Line to adapt the development of the Bingcaogang III district, area along the Jinsha River, Yanbian new town and Ertan landscape spot. The traffic road planning will also serve for the Panzhihua Steal factory, mining bureau, and Panzhihua mine factory. More investment will be used in rebuilding the Jinwu Road, Zonglong Line and Dujin line which form a chain line to adapt the development of the Jinjiang industrial developing district and to bring the future economic developing hotspot into the new traffic network.

The project is a component of road traffic plan. The front section of Binjiang Road will connect Jiangnansilu Roads with the constructed Binjiang Road to form a double way in the downtown area. The last section of the Bingren Road is a extension of the front section. This road will connect the future urban centre with the Renhe district. The construction of the last section will strengthen the density of the urban road network and alleciate the pressure which brought by the traffic in urban centre. It will also make positive effect on developing the new urban. It is therefore that the road construction suit for the road traffic plan.

Accordance with the Urban Drainage Plan

The sewage WWTPs will be built in Geliping, Taojiadu, Hemenkou-Qingxiangping, Duren, Bingcaogang, Nongnongping, Panmi, Jinjiang and Renhe according to the drainage plan. The scale of the Bingcaogang sewage WWTP which has already been constructed is 30 thousand m3/d�while the Renhe sewage WWTP, which is under-construction, is 20 thousand m3/d.

The interceptor and trunk sewers of this project consists of the first and second level interceptor and trunk sewers in Qingxiangping sewage WWTP, Wushisi~ Bingcaogang interceptor and trunk sewers and some sub-trunk pipe. To suit for the interceptor and trunk sewers construction, Qingxiangping sewage WWTP is planned to be constructed at the same time (details see Appendix 5).

It is obviously that the interceptor and trunk sewers construction is in accordance with the Urban Drainage Plan.

Rationality analysis of the project

Rationality analysis of incline retaining wall

The incline retaining wall is a special riverbank slope protection type, designed for the waste slags disposal field along the Jinsha River. In the feasibility report of the project, different methods had been compared for different slags fields.

(1) West slag field of Panzhihua Iron and Steel Group

The West Slag Field of Panzhihua Iron and Steel Group which formed from 1970 to 1993 by slags spoiling is more than 100m high and more than 1km long, the land occupation of which is more than 40ha. The quantity is nearly 40,000,000 t. The slags contain the vanadium and titanium which can be extracted and refined. Because of the restriction by economic and technical level, there is no large-scale integrated exploitation for the waste. To reduce the environment impact, the methods which can be chosen are blocking with retaining wall or moving to other place that is far from the river. Details of advantages and disadvantages of different schemes are listed in Table 2-12.

Table for scheme comparison of West Panzhihua Iron and Steel Group Slags treatment Table 1-12 Scheme Measure Funds Merit Defect

1

Concrete slope protection and block cage spats below the design flood level; 3-dimension net, grill protection slope above the level, spurt planting earth

Low

Use existing retaining wall for slags, craft is simple, time limit is short, expense is low and easy to maintain and comprehensive utilization

May cause soil erosion when faced grand scale flood

2

Build the same height concrete protection slope, plant the cane vine vegetation from the top

Medium

Effectively avoids the metallurgy slags entering the river, the craft is quite simple

Big resilience, large investigation demolish and backfill earth and stone after comprehensive utilization may cause new environmental problem

3 Piles up the slags far High Besides the soil erosion Based on the local

away the Jinsha River and urban area

in transporting process, may completely avoid metallurgy slags entering river, effectively restores the landscape

condition restriction, difficult to find appropriate site, may cause new environmental problem, long time limit and high expense

It can be seen from Table 2-12, every scheme has its advantages and disadvantages respectively. The scheme 3 may thoroughly solve the metallurgy slags problem. But because of the restriction of topographical condition, it is difficult to find field location with long time limit and high expense. To transport the slags by 8t truck, it will cost 13 years and RMB 40 million Yuan. The scheme 2 is more effective than scheme 1 but use more funds. Because the slags have formed stable slope, scheme 1 just need to maintain the surface with simple craft, short time limit and little expense. Therefore, scheme 1 is more economic proper than scheme 2.

It can be concluded from the above analysis that scheme 1 is better than scheme 2 and 3 in the view of environment protection and resource utilize. The slope protection type is therefore rational.

2) Slag field of Panzhihua Coal Group

The slag field of Panzhihua Coal Group is more than 200m long and more than 20m high, the land occupation of which is more than 5,000m2 and more than 0.3 million tons slags have piled up. There is no protective measure on the field. Incline retaining wall is planned to used for protecting the slope of this slag field.

The scheme can effectively avoid slags collapsing and soil erosion. The craft is simple and the expense is low. It is rational from the environmental protection angle.

3) Waste disposal field of Panzhihua Cold-rolled Factory

The spoil ground of Panzhihua Cold-rolled Factory is at The Jinsha River bank of Shijiaping, with more than 1 million tons solid waste piled up and no protective measure taken. The waste disposal area lies on the west of Shijiaping, which is the piling field for solid waste from the cold-rolled factory. In the developing period in 2001, the area of the ground is restricted, and it formed mix-waste disposal area. The quantity of the slags is more than 1 million ton in the field with no protect measure. The slags protection slope has simple craft, short time limit and little negative impact. The scheme is rational.

Rationality analysis of the material fields

(1) Sand materials fields

The Jinsha River is a multi-sands river. It is easy to use and transport local materials. The proper quantities of sand pitting will not impact riverbed alteration. The sand quarry may locates on the spots as above and should according to the procedure. The environmental protection and soil erosion prevention measures should be taken.

(2) Stone material fields

The Panzhihua City has plenty of stone material which is easy to exploit. Most of the

exploitation spots are naked stone area. The exploitation may impact the surrounding environment. The environmental protection and soil erosion prevention measure should be taken.

(3) Backfilling field

Coal gangue in Baoding, furnace slag and steel slag in Panzhihua steel factory will be used for backfilling materials. This can reduce soil erosion and avoid negative impact. In the view of environment protection and water and soil conservation, this desin is rational. But to reduce the negative impact, environment protection measures should still be taken during construction.

Rationality analysis of construction waste disposal fields

There planned nine dregs disposal fields in the project region. Two of them make use of the local constructional dumping fields. It can reduce tempoarily land occupation. The capacity of the these construtional dumping fields can completely satisfy the request of the riverbank environment improvement project.
