INTRODUCTION

1.1. GENERAL BACKGROUND OF THE PRESENT PROJECT

Originally under the jurisdiction of Sichuan Province, China, Chongqing was designated in March1997as a Municipality directly under the control of the Central Government, the fourth afterBeijing, Shanghai and Tianjin. Chongqing has an area of 82,400km2 and a population about 31million, with 6 million inhabiting in urban districts. Due to its special location and economicadvantages, Chongqing has become the largest economic center in the west of China, theincreasingly important bridge and ties linking the so-called West Chongqing (Yuxi)-Chengduindustrial and economic corridor in the west, connecting the technological and economic zonesalong the east coastal line of China through the Yangtze River via the Three Gorges to the east.

According to the Official Reply to the Overall Urban Planning of Chongqing Municipality by theState Council of P. R. China (GUOHAN [1998] File No.108), Chongqing, one of the mostimportant cities in the southwest of China and the upper reach of the Yangtze River, one of themost influential industrial bases, transport and traffic hubs and trade ports nationwide, her urbanconstruction and development shall be achieved through a strategy for sustainable development,in harmony with her economic, social, demographic, resources and environmental conditions.

According to the requirements for construction of a municipality to be a city leader in the region,Chongqing has been expected. to develop into a modern city, with prosperous economy,developed sciences and education, social civilization, complete facilities and pleasantenvironments, featuring unique landscapes as a "hilly city", "river-side city". Meanwhile, theOfficial Reply requests Chongqing to develop the urban districts in a controlled way, by takingeffective measures construct cluster quarters in suburban areas, improve and deepen city andtown system planning, raise funds through diversified channels, speed up construction of theurban infrastructure so as to change the situations of traffic congestion, water supply shortage,poor drainage, etc. throughout Chongqing Municipality as soon as possible.

The Chongqing Urban Environment Project approved by the World Bank in Fiscal Year 2001,has been designed to address pollution problems in the Municipality by providing a blend of bothkey infrastructure investments and institutional reforms. The objective of the Chongqing UrbanEnvironment Project (CUEP) is to provide a safe environmental setting for the sustainable long-term economic growth of urban areas in Chongqing Municipality (CM). The project wouldsupport the Municipality in implementing the first phase of a long-term urban environmentalimprovement program to recover from past environmental degradation, provide an adequatesupply of safe water and maintain water quality at levels that are compatible with the needs ofthe wider Yangtze River Basin.

Since approval of the loan ($200 million) it has become apparent that there will h'Ž significantsavinng from the loan (estimated at a-_ .ately $60 to $70 million) which may be r! ai.vcatedfor existing and/or new project components. The basis for this estimate is the trend inprocurement activities, namely: (a) bid prices of already awarded contracts average between 50percent and 60 percent of the estimated project costs indicated in the Project AppraisalDocument; (b) reductions in the scope of works, (c) cost reductions arising from refined detailedengineering design, and (d) loan savings due to works being completed along with ongoing bundroad works, ahead of schedule using Chongqing's own funds.

As of November 2002, Chongqing Municipality began to enter in a dialogue with the World Bankconcerning a second possible loan to finance both urban and environmental projects in

KOGREALU - BYN - !, 2 35 01K32 2-.G P. 1



Chongqing, subsequently known as the Chongqing Small Cities Infrastructure ImprovementProject (CSCP). As initially outlined the project focused on four broad sectors:

* Infrastructure construction to support the development of business parks;

* Water Supply;

* Bund Roads (including flood control/protection);

* River Harness (Wastewater and Flood Control/Protection).

As the preparation of a number of the below projects was relatively well advanced, it has beenproposed that these projects could be possibly financed using the loan savings from the firsturban environment project in Chongqing, the CUEP.

The following sub-components are part of the CUEP 1 New Components financed from loansavings:

The location of these sub-components is illustrated on figure on the following page.

As some if not all sub-projects may have significant impacts on the natural or socialenvironment, it was decided in agreement with the World Bank to prepare a Category AConsolidated Environmental Assessment (EA) for each of the 3 Sectors of concern for theCUEP 1 Loan Saving Project, i) Sanitation components, ii) Water supply components andiii) River embankment components.

To carry out the preparation of these 3 Consolidated EA, the Project Management Office (PMO)for WB Loan Financed Project in Chongqing appointed CISDI Engineering Co., Ltd.

CHONGQING URBAN ENVIRONMENT PROJECT - NEW COMPONENTSCONSOLIDATED EA FOR WASTEWATER COMPONENTS

1.2. GENERAL BACKGROUND FOR EA

1.2.1. CLASSIFICATION OF EA

In accordance with PRC National Regulations and the World Bank Operational Policy 4.01related to Environmental Assessment, the concerned wastewater components of the Project fallunder the Category A project and as such, they require full EA.

1.2.2. PRINCIPLES & METHODOLOGY FOLLOWED

The project technical and financial preparation was carried out by Chinese local organizationsand has been supported by various sources of international assistance to CUEP, includingSOGREAH, the Design Review and Advisory (DRA) Consultant to the Chongqing ProjectManagement Office (PMO), the responsible institution for the overall preparation of the project..

In accordance with the Government Regulation "Strengthening Environmental ImpactAssessment (EIA) Management for the Construction Project Loaned by Intemational FinanceOrganisation" of June 21, 1993 and the World Bank Safeguards Operational Policy, the ProjectPMO, has commissioned the CISDI Engineering Co. Ltd to carry out the preparation of the3 Consolidated EA studies for the CUEP Loan Savings components.

The Consolidated EA of CUEP II, China and the Consolidated EIA of Chongqing EnvironmentProject (CUEP I), China (hereinafter referred to as Consolidated EIA) are based on the individualElAs of the subprojects. CISDI Engineering Co., Ltd. compiled the Consolidated EIA Report ofCUEP I and the Consolidated EIA Report for Infrastructures of CUEP II, China, EnvironmentalManagement Plan and Summary of EIA.

Similarly, Resettlement Action Plans (RAP) for each of these 3 subcomponents are currentlyunder preparation.

This Consolidated EA has therefore been carried out by the CISDI with the assistance of theDRA Consultant; this overall assessment is based on the EA studies carried out by the variousorganizations for the individual components of the project.

1.2,3. COVERAGE OF EA

This consolidated EA has been carried out strictly in accordance with the State and Chongqinglaws, codes and criteria relating to environmental protection. It satisfies the Chinese EA system,whilst at the same time gives full attention to the requirements of the World Bank'senvironmental safeguards, and more precisely those of the Operational Policy 4.01 for EA.

The EA is based on the collection and use of existing materials and data supplementing missingmaterial by field investigations.

This Consolidated Environmental Assessment analyzes present environmental situation,potential impacts of project implementation and proposes mitigation measures in relation to thewastewater and embankments projects proposed for Bachuan River, Huaiyuan River, LaixiRiver, and Taohuaxi River.

3. ENVIRONMENTAL SITUATION AND DEVELOPMENT STRATEGY

3.1. PRESENT ENVIRONMENTAL SITUATION IN CHONGQING

3.1.1. PRESENT SITUATION OF WASTEWATER SECTOR

In 2001, the total amount of wastewater discharged in Chongqing Municipality was1,265 Million m3, including 812 Million m3 of industrial wastewater and 453 Million m3 ofdomestic wastewater.

In 2002, Chongqing had only three wastewater treatment plants (WWTP) i.e. Tangjiaqiao,Beibei and Yubei Chengnan, with a total capacity of 118,000 m3 per day. Chongqing is amongthe megalopolises in China with the lowest percentage of urban sewage centrally treated andthe lowest density of drain pipe networks, which was only 7.4% and 5.88 km/km2 respectively.In 2002, a total of 317 Million m3 of urban sewage were directly discharged into the YangtzeRiver in Chongqing. And the central urban districts, Wanzhou District and Fuling District werethe top three dischargers, the central urban districts discharging about 60% of the total. In thecentral urban districts, 16 water catchments discharge points have been reported along theYangtze and Jialing Rivers, while about 500 wastewater drain outlets are reported on the northand south banks of Jialing River and the east and west banks of the Yangtze River.

After completion of the Three Gorges Reservoir, the water velocity in the Yangtze River will falldown to 0.38 m/s from the present 3.8 m/s, causing a significant reduction in the self cleaningcapacity, which in return would probably cause the pollutant concentration in the river sectionsrunning through the central urban districts to increase by 34.5%.

The length of wastewater drain trenches/pipes per capita in Chongqing is only 0.2 m, lowerthan 0.27 m the average of cities nationwide. And some of the wastewater drainage systemshave been operating for over 40 years, now in poor conditions.

With a tremendous amount of urban sewage being directly discharged into the Yangtze Riverand Jialing River without any treatment, the surface water environmental quality along thesections of the Yangtze River running through the central urban districts has seen 6 indicatorsexceeding the standard for Category IlIl water area. This is quite out of harmony with the waterenvironmental control efforts taken since the cut-off dam of the Three Gorges was completed.

In September, 2001 the drainage project of the central urban districts (Phase I) financed withloans from the World Bank was already engaged. The loans from the Cooperation Bank ofJapan were used for Phase II project in 2003. In a principle of planning at one go,implementing in different phases the project has been executed by perfecting the cDnstructionof the secondary sewage treatment and sludge treatment systems on the basis of thepretreatment in Phase I. It was scheduled to complete the project by the end of 2005.

However, in view of the poor ecological environmental conditions in the Three GorgesReservoir area, the Central Government requested the wastewater drainage project of thecentral urban districts to be implemented faster. Therefore, the construction of the project hasbeen speeded up and is expected for completion by the end of 2004. Since then, more than60% of sewage in the central urban districts will be treated, and Jiguanshi WastewaterTreatment Plant and Tangjiaqiao Wastewater Treatment Plant will have a daily sewage

treatment capacity of 900,000t/a (in 2010) and 1,200,000/a (in 2020), allowing discharge oftreated effluent in compliance with relevant standards and consequently reducing the amountof pollutant discharged into the two rivers in the central urban districts by about 230,000t eachyear.

Meanwhile, construction of 19 sewage treatment plants, several primary and secondarysewage networks of the first lot in the Three Gorges Reservoir area have been started sincethe end of 2001 in 13 districts, cities or counties including Jiangjin, Changshou, Fuling,Fengdu, Zhongxian, Wulong, Wanzhou, Yunyang, Shizhu, Kaixian, Fengjie, Wuxi, Wushan.

This represents an investment of 2.48 billion RMB in total, for a treatment capacity of510,000 1/day. Ten of the 19 sewage treatment plants were constructed and put into trialoperation in June, 2003. The trial operation shows that the tail water discharged out of thesewage treatment plants meet the national water quality standards, and the sewage treatmentplants, with daily treatment capacity of 300,000t, can treat 50% of the sewage produced in thesurroundings.

In addition, Qianjiang District, Dianjiang County and Nanchuan City, which also may affect theThree Gorges Reservoir have already started urgent construction of VWVTP.

The construction of wastewater treatment facilities in Chongqing Municipality will play animportant role in improving the Yangtze River water environmental quality, promoting thesustainable development of Chongqing Municipality.

.1.2. PRESENT SITUATiON OF SOLID WASTE COLLECTION AND TREATMENT

In 2001, 2.75 million tons of solid waste were generated in Chongqing Municipality with awaste handling rate of 85.09%. In the central urban districts, waste generation amounted to1.15 million tons, with an handling rate of 98%.

Changshengqiao Sanitary landfill with a capacity of 1500 t/d was completed as part of CUEPand replaces some of the existing eight open dumpsites in the central urban districts; theselatter sites had a total disposal capacity of 2,930 t of waste per day with stacking and partialincineration. Most of these latter sites are full and overloaded, resulting in serious pollution tosurrounding soils, ground water and air.

Tongxing Landfill in Beibei District and Heishizi Landfill in Jiangbei District with proposedcapacities of 1,500 tVd and 1,000 t/d are under planning. Also, landfills with different capacitieshave been planned or are already under construction in the Three Gorges Reservoir area andother districts, cities and counties. Chongqing Municipality is now planning to construct 4hazardous waste treatment plants, and the preliminary engineering of the hazardous %P.'astetreatment plants in the central urban districts and Changshou District is nearly drawing to aclose.

3.1.3. PRESENT SITUATION FOR OTHER ENVIRONMENTAL INFRASTRUCTURES

The west of Chongqing Municipality faces water shortage and the water use in TongliangCounty, Dazu County, Yongchuan City mainly relies on water con7Žrvation by building dams onthe secondary rivers or rainwater conservation by building reservoirs. However inappropriatelevel of wastewater collection and treatment causes serious pollution on such secondary riversas Bachuan River, Huaiyuan River, Laixi River, sources of water supply. This situation worsensthe conflict between water supply and pollution, affects the ecological environmental quality andbottlenecks sustainable development in the west of Chongqing Municipality.

3.2. OVERALL DEVELOPMENT PROGRAM OF URBAN ENVIRONMENTALINFRASTRUCTURE

3.2.1. OVERALL DEVELOPMENT FRAMEWORK

In compliance with the decision to expedite implementation of the urbanization strategy,Chongqing Municipality has formulated an overall framework for the development program ofenvironmental infrastructure (environmental facilities) and educational, scientific and culturalfacilities including traffic, communications, energy, water supply & drainage, landscaping,environmental protection, natural calamities prevention and fighting, etc.

The program relies on a rational and sustainable use of resources, strengthens ecologicalenvironmental construction and protection in towns and cities, tries to create a developmentpattern with growing production, well-being living and good ecological conditions, basically toprovide towns and cities with complete functionalities meeting the needs of economic and socialdevelopment.

3.2.2. SECTOR ARRANGEMENTS FOR THE DEVELOPMENT PROGRAM

The concerned sector arrangements for the development program of Urban EnvironmentalInfrastructure (Environmental Facilities) mainly include:

3.2.2.1. WASTEWATER MANIAGE;,1ENT

In November 2001, the State Council gave official approval to Water Pollution Prevention andControl Planning for the Three Gorges Reservoir Area and Its Upper Reach, which states thatby 2005 water quality at the main controlled sections of water areas in the Three GorgesReservoir and its affecting zone in Chongqing must meet the national surface waterenvironmental quality standard Category IlIl, and by 2010 the entire water quality must meetwith Category II standard.

After the key environment projects (including: water drainage project in urban districts, sewagetreatment projects in 15 districts and counties in the Three Gorges Reservoir area and 9regional central cities in the affecting zone, sanitary sewage treatment facilities and matchingsewage pipe network project financed with loans from the World Bank) are completed in the10th Five-year Plan period, the percentage of urban sanitary sewage centrally treated all overChongqing Municipality will rise from 7.2% in 2001 to more than 60%, that in the Three GorgesReservoir area to more than 90%. It is estimated that a total of RMB 8.65 billion is required forthese projects.

3.2.2.2. URBAN SOLID WASTE MANAGEMENT

As set forth in the Water Pollution Prevention and Control Planning for the Three GorgesReservoir Area and Its Upper Reach, Chongqing Municipality is placing emphasis onconstruction of the following solid waste treatment projects in the 10th Five-oear Pian period:

e Construction of Changshengqiao Sanitary Landfill, Tongxing Waste Incineration DisposalSite, Heishizi Sanitary Landfill in the central urban districts, sanitary landfills in 13 districtsand counties in the Three Gorges Reservoir area and 9 regional central cities in theaffecting zone, designed to dispose of sanitary waste of 8,900 t per day in total. It isestimated that RMB 3.06 billion are required;

* Construction of 4 hazardous waste treatment centres designed to treat hazardous waste1 ,480t per day, 540,000t per year. Cost estimate is RMB 330 million;

SOGREAH - BYN - N°2 35 C032 1. 1- A. 21S- 2CC PAa. 1 4




* Construction of ports in the urban districts, Wanzhou District, Fuling District, WushanCounty, etc. for collection and transfer of vessel sanitary sewage and waste. Cost estimateis RMB 536 million.

With the construction and operation of the above projects, more than 70% of the urban sanitarywaste will be treated to be harmless all over Chongqing Municipality, and more than 90% in theThree Gorges Reservoir area.

3.2.2.3. PLANNING OF OTHER ENVIRONMENTAL INFRASTRUCTURE PROJECTS

* Water supply project

In the year of 2010, RMB 11.5 billion will be invested to increase the daily water supplycapacity by 1,980,000m3, of which RMB 6.5 billion will be in the central urban districts toincrease in the daily water supply capacity by 900,000m3, also improve the potable waterquality as purified water; RMB 5 billion will be in the further located counties (autonomouscounties, cities) and towns under the county organizational system to increase the dailywater supply capacity by 1,080,000m3, water pipe networks by 1,800km;

* Landscaping project

Focusing on theme parks, efforts will be continuously taken to ensure construction ofgardens and parks. Five large parks are planned in the central urban districts, and 40 parksare planned in the further located counties (autonomous counties, cities), with aninvestment requirement of RMB 1.65 billion;

* Secondary river pollution control project

It includes the integrated control of Taohuaxi River, Qingshuixi River in the central urbandistricts and 39 secondary rivers in the further located districts and counties. After theconstruction of the whole project, the water environmental quality will be improved to agreat extent throughout Chongqing Municipality. It is estimated that RMB 4.8 billion will berequired;

o Geologic hazard prevention and control project in the Three Gorges Reservoir area

According to the geologic hazard prevention and control planning in the Three GorgesReservoir area, the project will be implemented in two phases, requiring an investment ofRMB 5.7 billion in total.

After completion of the above mentioned wastewater and solid waste managementprojects, the water quality in Chongqing Section of Yangtze River will likely be significantlyimproved and comply with Grade IlIl quality standard. With further treatment of industrialand agricultural wastewater which fails to meet the standards of discharge, the waterquality in non urban section of Yangtze River is expected to comply with Grade II qualitystandard.

3.3. DEVELOPMENT PROGRAM COMPONENTS UNDER WORLD BANK LOANS

3.3.1. DEVELOPMENT PROGRAM FOR IMPROVEMENT OF INFRASTRUCTURE IN MEDIUM- AND

SMALL-SIZED TOWNS

Urbanization lies its core in displacement of the excessive rural labor forces, sufficientemployment in the urban and rural areas. Its essence is to improve the people's living standardby focusing attention on the people. The most urgent mission is to enforce the industrial support,radically change the present situations of large urban districts coexisting with large rural areas

YN - N hEf. , C C PA. 1 5



and outstanding dualistic structure as well. Without the industrial support of towns, urbanizationwould be like water running with no sources, trees growing with no roots, and towns would bevoid, dead and shell-like towns with no markets.

The characteristic industrial parks are usually at the interface between towns and rural areas.So, to attract industries and let them settle down in the medium- and small-sized towns,integrate and spur on the local economic growth, planning and construction of the necessaryinfrastructures become an essential prerequisite. This relies on the town resources and regionaladvantages, receiving radiation of funds and technologies from large- and medium-sized cities,optimizing and breeding dominant industries, absorbing the excessive rural labor forces,developing the secondary and tertiary industries in towns to be stronger contributors toeconomic growth, improving the people's living standard and invigorating the towns withprosperous industries. In this regard the improvement of the infrastructure in medium- andsmall-sized towns is one of the most important measures to urbanize the county (district, city)seats and central towns with higher priority.

Meanwhile, the improvement of the infrastructure in medium- and small-sized towns will not onlyintegrate and attract preponderant industries to settle down for economic development, but alsohelp restructure the industries and wash out the behindhand enterprises, achieve transformationfrom extensive resource utilization to output of higher-added-value products, thus reducing theproduction and discharge of pollutants accordingly. The other benefit is that items which used tobe scattered, hard to control in the past wiil be under standardized management and pollutioncontrol will be relatively centralized according to the Central Government requirements toimprove the operability, uniformity and unit benefits- of pollutant reduction, which is not onlyfavorable for standardized management by the environmental protection management andmonitoring departments, also for reduction of total amount of pollutants and regional control,improvement of local environmental quality.

At present, 30 projects aiming for improvement of infrastructure in medium- and small-sizedtowns have been approved by Chongqing Municipality, and the area of land for their starting upand expansion covers 63.4km, of which 16.68km have been prepared. According to theplanning, the investment for improvement of the infrastructure in medium- and small-sized townsin Chongqing Municipality will amount to RMB 20 billion in 2007, 145km2 of land will beprepared, and about 3,000 enterprises will reside in, generating a production value of RMB 170billion, a revenue of RMB 10 billion, employing 600,000 persons, and thus fulfilling the strategictarget of "re-establishing a new industry in Chongqing".

Of the projects for improvement of infrastructure in medium- and small-sized towns, six areplanned to be financed with loans from the World Bank, as presented in the following Table.

3.3.2. DEVELOPMENT PROGRAM FOR RIVERBANK (BUND ROAD) PROJECTS

Most of towns and cities in Chongqing Municipality are located before hills, close to rivers. Dueto the factors such as long-term rainwater scouring of slopes, soil erosion, uncontrolled discard , -

of industrial and sanitary wastes and effluents, the secondary rivers of the Yangtze River andJialing River have encountered the problems of mud accumulation in riverbed, serious pollution,which affect the people's living standard, jeopardize the physical and mental health, affect theurban traffic and transportation, worsen the conditions for flood control and investmentattraction. To this point, the construction of riverbank road and flood control projects is not onlyessential to urbanization, also long-awaited and image-showing to the people.

3.4. SUMMARY OF CSCP

Chongqing Small Cities Infrastructure Improvement Project (CSCP) mainly consists of bundsubprojects, water supply subprojects, infrastructure improvement and environment subprojects(wastewater) in medium- and small-sized towns under its jurisdiction. These subprojects aremostly located in the West Chongqing Corridor with convenient traffic and transportationconditions, close to Chengdu-Chongqing Railway and Chengdu-Chongqing Expressway. To giveattention to the development of other regions, particularly the economic development and cultureproperty protection in the regions of minor ethnic groups, similar subprojects have also beenplanned in Qianjiang District, Wulong County in the east of Chongqing Municipality. TheUrbanization and Environment Project is designed to increase the capacity of infrastructure liketraffic and transportation, water supply, promote industrial construction in the medium- andsmall-sized towns with integration of small town construction, environmental protection andindustrial restructuring, hasten the urbanization process and promote sustainable developmentof environment in Chongqing Municipality.

The CSCP financed with loans from the World Bank are one of the important measures forChongqing Municipality to implement the urbanization strategy. These projects and the projectsites usually have the following features:

* Close to the large- and medium-sized cities or medium- and small-sized towns planned byChongqing Municipality, the subprojects are arranged with favorable traffic andtransportation, economic and technological conditions, having sufficient labor force, landand technical resources, much potential of industrial integration and development forurbanization;

• The subprojects, mostly related to infrastructure and environmental protection in towns andcities, will a great driving force for industrial restructuring, traffic and transportationimprovement, investment environmental improvement and ecological construction in theadjacent tocvns and cities, essential to the sustainable development of the adjacent townsand cities;

* The subprojects are all urgently needful or lacking for the towns and cities to carry outindustrial restructuring, living and investment environmental improvement;

* The subprojects are closely related to fostering of the local supporting industries;

* The subprojects are mutually supplemented to each other, constituting the cornerstone forimproving the infrastructure of Chongqing Municipality for urbanization;

* The subprojects are commonly expected and supported by the local governments and thecommon people.

4. DESCRIPTION OF THE WASTEWATER PROJECT COMPONENTS

As presented in Section 3 of this report, the CUEP 1 New Components supported by the WorldBank addresses 3 main sectors, the Wastewater Sector, the Water Supply Sector and the RiverEmbankment Sector.

The cities concerned by the wastewater component are also generally concerned by riverembankment subprojects, with the aim to better integrate pollution control and urbandevelopment. In this case, the embankment subprojects and issues are presented in the Riverembankment Sector Consolidated EA. The Present Consolidated EA addresses the WastewaterSector Component only.

4.1. PROJECT COMPLIANCE WITH NATIONAL AND MUNICIPAL STRATEGIES

This section mainly provides a consolidated description of the proposed new Components'conformity with Chongqing Urban Environment Project (CUEP I) and their compatibility withrelevant planning programs.

The proposed wastewater subprojects concern integrated environmental control of threesecondary rivers. They are designed to intercept urban sewage and deliver it to the WastewaterTreatment Plants (WWTP) constructed under Chongqing Municipality's jurisdiction. Theyconstitute complements to CUEP I. As such, they are designed to comply with the principlesformulated for the CUEP I regarding design, public involvement, resettlement, compensationand environmental protection.

As required in the Overall Planning of Chongqing Municipality and the File issued by the StateCouncil of P. R. China (GUOHAN [1998] File No.108), the urban construction and developmentof Chongqing Municipality shall be done under a strategy for sustainable development, inharmony with its economic, social, demographic, resources and environmental conditions. TheCUEP I and the WB Loan Savings subprojects comply with this overall development strategy.

According to the requirements defined in the State Council's official reply to the Water PollutionPrevention and Control Planning for the Upper Reach o' th,- Yangtze River (GUOHAN [2001]File No. 147), water quality at the main controlled sections of water areas in the upper reach ofthe Yangtze River must meet the national surface water environmental quality standardCategory IlIl by 2005 and Category II by 2010.

The WB Loans financed components of CUEP I which will actively promote industrialrestructuring, clean production and pollution control fully comply with the water pollutionprevention and control planning strategy.

Chongqing Municipality is also facing an urgent need for ecological environmental restoration.The major ecological problems include a too low percentage of forest cover of only 20.98% (theState required over 45%), difficulties in forestation; severe soil erosion (140,000,000 tVa of soiland sand flushed into the rivers); frequent natural calamities such as floods and landslides,insufficient arable land resources. To enforce the ecological conservation strategy, ChongqingMunicipality has addressed "Prevention and Control of Environmental Pollution andConservation of Ecological Balance" as one of the four priorities of economic and socialachievements by 2015. The ecological conservation planning of Chongqing Municipalityemphasizes integrated control of small river basins, the construction of water supply projects in

SCG2EA- -, f, - NC2 35 rq32 1 - AI ; .._ ,2CC` P4c, 20



the west of Chongqing, the strengthening of water pollution prevention and control of thesecondary rivers. In this respect the WB Loans financed components of CUEP I fully complywith the ecological conservation planning of Chongqing Municipality.

4.2. WASTEWATER COMPONENTS PRESENTATION

There are three wastewater subprojects using the loan savings under Chongqing UrbanEnvironment Project financed with loans from the World Bank.

The subprojects are all planned to: improve the environmental quality, enhance the urbanizationlevel; increase industrialization percentage, improve the basic environment like flood prevention,sewage treatment in central towns and cities by construction of environmental infrastructure andintegrated environmental management for urbanization, lay down solid environmentalfoundations for sustainable development with economic development in harmony with ecologicalenvironmental protection in the process of urbanization.

5. WASTEWATER PROJECT ALTERNATIVES

5.1. GENERAL OBJECTIVES OF CUEP1

The objective of the Project is to assist Chongqing in the first phase of its long termenvironmental improvement program to: (a) improve urban environmental services with a view toreducing environmental degradation of its water and land resources; (b) provide an adequatesupply of safe water to its growing urban population and economy; (c) maintain water quality atlevels which are compatible with the needs of the wider Yangtze River basin and of the ThreeGorges Reservoir.

5.2. M'YA1A IA CRITERIA rOR AL-ERNAT-!/E SELECTION

Various alternatives were considered prior to project definition, which were compared based onthe following main selection criteria:

* Site location for the treatment plant: comparison was mainly based on distance of site toserviced area (length of main sewers), to nearest access road and receiving river (length oftreated effluent outlet);

a Site land use: this criteria considers basically land acquisition and resettlement needs forthe plant. However this criteria was not found critical as alternative sites anticiPated were allcultivated land;

* Receiving river Function Class: not a critical criteria as the alternative plant sites wereconsidering the same rivers for discharging treated effluents;

* Topography: a major criteria as it influences the gravity flow and the earthwcrks for layingthe mains;

* Process and design: Criteria is mainly based on investment cost and operational easiness.

5.3. ALTERNATIVE WITHOUT PROJECT

Without project, the already poor water quality of the Chongqing Municipality rivers will continueto degrade, resulting in the progressive vanishing of the river life, and eventually increasedpollutant and nutrient load to the Three Gorges Reservoir, speeding up the eutrophicationprocess of the water body with disastrous results on reservoir ecology, fisheries and water uses.After completion of the Three C-,orpe- R.eservoir, the water velocity i . ', a River will falldown to 0.38 m/s from the present b.8 m/s, causing a significant reduction in the self cleaningcapacity, which in return would probably cause the pollutant concentration in the river sectionsrunning through the central urban districts to increase by 34.5%. Urgent action is required toavoid the urban branches of the Yangtze river system to turn into open sewers.

The WB Loan Savings Components related to the wastewater sector will reduce by more than3,00C ,Lons/year the BOD5 load presently discharged in the Bachuan, Huaiyuan, Laixi andTaohuaxi rivers, all parts of the Yangtze basin. The whole wastewater component project under

SOOiGR=AH - BYN - N'2 35 C032 R 3 1,- : .' , 22 Fe..- 26

CHONGOING MUNICIPALITY - THE WORLD BANKCHONGQING URBAN ENVIRONMENT PROJECT - NEW COMPONENTS


development will achieve the treatment of almost 600,000 m3 /day of urban wastewater, whichwill eventually correspond to a pollution abatement of 26,000 t/year.

Aside from river quality improvement, necessary improvement of sanitation and public health inurban areas totalizing several millions population is not questionable, mainly after those recentand threatening experiences with new viral epidemics which spread easily through waste water.

Both in terms of economic development, public health and environment, the "non project"situation is not an acceptable alternative.

5.4. ALTERNATIVE LOCATION OF FACILITIES

This project is mainly a river embankment project, to which extension of main sewers is attachedin order to benefit the works required for dike construction. There is no real sewer alternativeroute other than the dike location alternatives presented in the concerned consolidated sectorEA.

5.5. A E_-ERNATIVE CE i3 l & T W jm\ENT D.' S S

Mituo Town, Fulong Town and Longshui Town are distributed along both east and west banks ofLaixi River, 4 to 8km from each other. The process design analysis compares 4 options toestablish sewage treatment plant:

Option 1: Mituo Town, Fulong Town and Longshui Town each build up one sewage treatmentplant with capacities of 1,500m3/d, 2,OOOm3/d and 30,00Om 3/d respectively in Phase I;

Option 11: Mituo Town and Longshui Town each build up one sewage treatment plant withcapacities of 2,000m3/d and 30,000m3/d respectively in Phase l;

Option III: Longshui Town alone builds up one sewage treatment plant with capacity of30,000m3/d in Phase l;

Option IV: Fulong Town and Longshui Town each L'jild up one sewage treatment with capacitiesof 2,500m3/d and 30,000m3/d respectively in Phase 1.

For the site selection concept of sewage treatment plant, Option I features short sewageinterception main and short laying depth, no pumping station required, convenient constructionaccess, easy management during operation and lower investment. Considering the planning ofthe three towns' development and the feature of Fulong Town, which is a simple agriculturaltown, with limited sewage of standard domestic quality and located near Longshui Town, it is

SOGREAHi-BYN -ND235CQ32 R- A -22>t P-G- 28




recommended to intercept its sewage and send it to treatment plant in Longshui Town. Option IIIis the preferred option.

The design compares the Oxidation Ditch and Sequential Batch Reactor (SBR) to be used forsewage treatment and plant operation. The Oxidation Ditch is proposed because of lowerinvestment and easy operation management.

5.6. ALTERNATIVE MANAGEMENT FOR SLUDGE

The network will collect a significant proportion of industrial effluent, with the risk of accumulationof contaminants as heavy metals in the sludge. For this reason, sludge reuse is not consideredas an acceptable alternative.

According to Chinese regulations, the quality of sludge leaving the WWTP must satisfystandards which can only be complied with after a stabilization process. Sludge will then bestabilized prior to disposal in suitable sanitary landfills. Alternative without stabilization is thus notconsidered.

6. BASELINE ENVIRONMENTAL CONDITIONS

6.1. PHYSICAL ENVIRONMENT

Chongqing is also called Yu in Chinese for abbreviation, and one of the four municipalitiesdirectly under the Central Government, located at latitude between 28010' and 32013' north andat longitude between 105011' and 110011' east. Chongqing, with a total area of 82,403km2,bounds on the west by Sichuan Province, south by Guizhou Province, east by Hubei Provinceand north by Shanxi Province, and connects the eastern China well developed to the westernChina abundant in resources.

Chongqing is located in central part of Southwest China and in a center strip of GreatDevelopment of West China. Chongqing is also a very important central municipality onupstream of The Yangtze River, and acts as an important industrial base, transportation centerand trade port in China.

For Changshou District, Dazu County and Tongliang County, which involve integrated rivercontrol, the specific locations of them in Chongqing administrative region are shown in theattached drawings(Appendix 2).

C.6.1. CL!MATE

Chongqing is lccated in medium sub-tropical humid monsoon area, and features hot-summer-cold-winter, rich but seasonally uneven rainfall, high humidity, cloudy weather, long frostlessperiod and low wind speed. The average annual temperature is 16.9-18.8 OC, and averageannual, rainfall 814.8-1229mm, average annual relative humidity 77-81%. The leading windthroughout the year is of NE wind and N wind with average annual speed of 0.7-1.7m/s: Somearea is affected by the local terrain where the leading wind has the same direction as the valleyextends.

6.1._. HYDROLOGY

Chongqing is dominated by low mountains and hills, and suffers from the serious soil erosion.There are more than ten rivers, small or large, such as The Yangtze River, Jialin River, WujiangRiver, Daling River across Chongqing. But 96.9% of water resource is of passing waterresource, and therefore the water resource utilization per capita of Chongqing is only 720m3/aChongqing, amounting for 33% of the national average. There is lack of water in the western,southeastern and northern Chongqing.

Bachuan River originates from somewhere to the n. .h of Bachuan Town and runs through thistown, and finally joints the Huaiyuan River between Bailong Bridge and Yandu Bridge. BachuanRiver is 14.02km long and covers the basin of 57.8km2, with average annual flow of 0.68m3/s.Huaiyuan River originates in Dazu County and runs into Tongliang County through Tuqiao Townand then runs through Quande, Shixiang, and finally joins Xiaoanxi River in the place namedHetanshi located in old downtown of Tongliang County. Huaiyuan River is 73.1km long andcovers the basin of 536.3km2, with average annual flow of 6.44m3/s.

Laixi River is the main river and also the potable water source in Dazu County. It originates inBeiyun Village, Tianshan Town, Dazu County and runs through Zhongao, Longgang, Longshuiand Zhuxi up to Rongchang County, and then joins Tuojiang River in Hushi Town, Luxian Countywhich finally joins The Yangtze River. Laixi River in Dazu County is 71.4km long and covers thebasin of 929.3km2, with average annual flow of 12.57m3/s.

Taohuaxi River in Changshou District is the one of the major branches to The Yangtze River. Itoriginates in Wangshaopo of Xishang Mountain in Changshou District, and runs through Yihe,Shiyang, Gelang, Tiantai, Xlnshi, Fuhe, Bake, Duzhou, Fengcheng and joins The Yangtze Riverin the place named Shiliangzi, Hejie, Changshou District.

6.1.3. SURFACE WATER QUALITY

Water quality monitoring data for river sections of Huaiyuan River upstream and downstream inMay 2003; monitoring data for ambient air quality and environmental noise level in May 2003,done by Environment Monitoring Station of Tongliang County.

Water quality monituring data for river sections in the vicinity of various proposed sewagetreatment plants along Laixi River, ambient air quality and environmental noise level in July2003, done by Environment Monitoring Station of Dazu County.

Water quality monitoring data for river sections from Gelan Bridge to Andao Bridge acrossTaohuaxi River in 2002, for ambient air quality in Feb., 2003, and for environmental noise levelrelated to the proposed project in June 2003, done by Environment Monitoring Station ofChangshou District.

Surface water of these 3 secondary rivers related to the proposed projects is severely pollutedand ail main pollutants fail to comply with the standards. Serious failure of conformance of BOD 5in Taohuaxi River and NH3-N and Total-P in Three Rivers, mainly result from the domesticsewage and irrigation effluent which are directly discharged into rivers without treatment. Forpetroleum pollutant and COD, the pollution level at and over Grade V may result from thedischarge of industrial waste water along the rivers.

In 2001, GDP in Changshou District is 5.57 billion RMB. In Duzhou Town and New TaohuaTown along the both banks of Taohuaxi River are mainly distributed the industries of ceramic,fertilizer, natural gas and machining.

6.3.3. INFRASTRUCTURES & SERVICES

So poor are the Infrastructure and flood-proof & drainage facilities in various towns alongBachuan River/Huaiyuan River in Tongliang County, Laixi River (hereinafter called Three Rivers).in Dazu County and Taohuaxi River in Changshou District, which are proposed for integratedenvironment control, that industrial waste water without due treatment and qualification fordischarge combines with the poor-treated agricultural waste water, domestic sewage and rainfallto flow into the rivers.

Flood-proof project has already completed for the section of Bachuan River within BachuanTown ranging from Xianyu Bridge north to Longmenti south, and waste water interception mainshave been laid onto the river bed in this section of Bachuan River. Water supply plant' in thenorth of Bachuan Town can supply water of 30,000m3 /d. Sewage is collected in the masonryconduits and then discharged into Bachuan River and Huaiyuan River. Due to impact fromindustrial waste water and domestic sewage, approx. 30,000t of waste is disposed at discretionat suburb and along both banks of the rivers. It thus causes serious organic pollution in riverwater bodies and terrible odor, and makes the rivers full of floating and foam. As a result, the cityappearance and people's mental and physical health are seriously deteriorated.

Longshui Town, Fulong Town and Mituo Town each has one water supply plant which cansupply water of 30,00Om 3/d, 1 ,500m 3/d and 2,300m3/d respectively. The water supply pipeworkfor Longshui Town and Fulong Town are 42km and 5.2km long respectively. The drains for theabove-mentioned three towns are 36000m, 350m and 350m long respectively and mainlyccnsist of masonry conduits. At present, the sewage drains are troubled by small cross sections,out of maintenance after years of service, popular collapse and serious silt-up. The limitedcapacity of drain easily leads to flood throughout downtown area in case of heavy rain. Only inthe section of Laixi River running through the center of Longshui Town exists 1km long masonryriver banks. Along banks of other sections of this river are piled by waste.

In Changshou District, there are two water supply plants: Ximen Water Supply Plant(36,000m /d) and No.2 Water Supply Plant located in Miaoshanpo. Domestic sewage is mainlytreated in septic tanks and then discharged. In downtown area, there are approx. 150 septictanks with a total capacity of approx. 8,000m3. Except the newly built residence areas whererainfall and sewage are respectively drained, rainfall and sewage are combined for drainage inother areas. The masonry drains are 10km long and carry the most of sewage into TaohuaxiRiver.

6.3.4. QUALITY OF LIFE

In 2001, the GDP per capita of Tongliang is 5445 RMB. Bachuan Town is awarded "IdealEnvironment for Human Habitant in China" and "Small & Civilized Town in China ".

Longshui Town is an economic center of Dazu County with developed business of hardware and,r:tium-specific chemic2l indt-try and has ample tourist resource of far-, - Longshui Lake.

Residents in urban and rural areas enjoy a growing incomes and impro.i,~ living standards.One employed person has an average wage of 8809 RMB per year while one person incountryside has an average income of 3456 RMB per year. Longshui Town is also one of 58demonstration towns in national small town construction plan.

In Changshou District, one employed person has an average wage of approx. 10,000 RMB peryear and enjoys a living standard like the people in Chongqing Municipality.

6.3.5. CULTURAL AND ARCHAEOLOGICAL VALUES

There is no relicts of cultural or archaeological value identified and reported from the projectsites.

6.3.6. SENSITIVE SITES

Due to the location of the project components either in urban areas or sub-urban agriculturalland, there are no ecologically sensitive areas neither protected areas identified near the projectsites.

No site of particular sensitivity is observed near the proposed WWTP sites. Urban areas arelocated at least 100 m from the WWTP borderlines.

In Tongliang, two sites of particular sensitivity to noise have been identified, located close to theriver embankments works and which could, in the future, be affected by the road traffic on theembankment: a residential area and a primary school.

In Longshui, two primary schools are located close to the future river embankment.

In Changshou, no site of particular sensitivity is observed.

These sites are indicated on the maps presented in Appendix 2.

3.4.1. INDUSTRIAL POLLUTIC;j

Except iarge- and rnedium-sized state-owned enterprises in the proposed areas, most of themedium- and small-sized enterprises lack appropriate sewage treatment facilities and contributeheavily to the pollution load in the proposed rivers (Huaiyuan River and Bachuan River inTongliang County, Laixi River in Dazu County and Taohuaxi River in Changshou District).Therefore, the industry and economy structures in these areas need to be re-organized. Themanagement shall be standardized. The pollution must be controlled from pollution source.

Based on following tables, it is observed that most of the industrial wastewater fail to meet thedischarge si- - -rds, and contribute as a main water poliution source in the project areas. Th-counter-me1_-uit.,' in the corresponding counties and district are to adjust industry structure andeliminate the enterprises with high consumption of resource and energy and serious pollutions;and organize smaller enterprises in industrial parks. Based on central treatment of chromium-bearing waste water produced during electroplating, the industrial park in Longshui Town willintroduce complete set of treatment facilities to improve further the treatment on chromium-bearing waste water, so as to meet the discharge standard even when the park is expanded.

It is estimated today that the potential contribution of the industrial wastewater to the WWTPinflows may represent 9.4% for Mandongzhipo WWTP (Tongliang) and 16.5% for WuguituoWWTP (Dazu). Proportion of industrial wastewater and its treatment measures and plans forTongliang and Dazu are detailed hereunder. For the sewer network extension in Taohua(Changshou), there will be almost no industrial flow as Taohua new township will be mainly thelocation of government agencies and residential area.

6.4.1.1. INDUSTRIAL WASTEWATER PROPORTION AND ITS TREATMENT MEASURES AND PLANS IN TONGLIANG

Tongliang has 65 industrial enterprises with considerable sizes, including silk, machinery,petroleum chemicals, construction materials and food processing, mainly located in BachuanTown, capital town of Tongliang County.

Industrial wastewater and domestic wastewater generated in Bachuan Town are dischargeddirectly into Bachuan River and Huaiyuan River without any treatment. At present, the rainwaterand wastewater are combined for discharge and most of sewers are of concealed stoneworksewer. Main polluters of industrial wastewater include Chongqing Longzhu Electricity Co., Ltd.,Tongliang Silk Co., Ltd., Tongliang Tianqing Strontium Salt Company, Fine ChemicalsCompany, Xianfeng Strontium Salt Company, Yeshoubao Amylum Sugar Factory and LindaIndustries Co Ltd. According to preliminary estimate, there is approx. 2570m3/d of industrialwastewater in Bachuan Town, accounting for about 9.4% of the total effluent wastewater ofBachuan Town at present.

According to planning, rainwater and wastewater are discharged separately in Bachuan Town.For Chongqing Longzhu Electricity Co., Ltd., most of wastewater is indirect equipment coolingwater, which will be recycled as much as possible to reduce effluent. For Tongliang Silk Co.,Ltd., the current wastewater treatment equipment can treat wastewater at a rate of 450m3/d,For other enterprises, the wastewater generated by them needs to be respectively treated bytheir own wastewater treatment equipment for qualified discharge into municipal sewer system,from which the wastewater is sent to the proposed wastewater treatment plant for centraltreatment.

6.4.1 .2. INDUSTRIAL WASTE'YATER PROPCRTiON AND ITS TREATMENTJT MEASURES AND PLANS IN DAZU

Longshui Town is the biggest market of small hardware in southeast China, an economic centerof Dazu County and also short listed in the town reform in China. Longshui Town sees somedevelopment of new and hi-tech industry such as vehicle and motorcycle spare parts businessdeveloped on basis of small hardware.

According to industrial wastewater and domestic wastewater discharge data about enterprises inind6strial park of Longshui Town, it is preliminarily estirnated that industrial wastewater isap,rox. 3300m3/d, accounting for 16.5% of the total effluent wastewater from Longshui Town atpresent.

According to the planning of the town, rainwater and wastewater are discharged separately inLongshui Town. In the Industrial Park of Longshui Town is located central treatment facility forelectroplating wastewater at a planned capacity of 1000m3/d (200m3/d at present). According tothe principle of separate discharge of rainwater and wastewater in industrial zone, the productionwastewater is discharged at rate of 1500m3/d, and treated by combination of separate andcentral treatments. Electrop!ating wastewater is treated within the electroplating area. Domesticwastewater is treated in H: domestic wastewater treatment facili;y featuring high efficiency andzero energy consumption or septic tank in the near future, and will be treated in wastewatertreatment plant of Longshui Town for discharge up to standard in the far future. Other productionwastewater will be treated by various works in industrial zone for discharge up to standard.

Industrial wastewater from Hongdie Strontium Business Company is about 380m3/d and istreated for discharge up to standard.

5^_RU - 5YN - N2S5 232 P .- * P 37



According to the planning of Longshui Town, industrial wastewaters from other small hardwareindustries shall be first treated in various works up to standard and then join the municipal sewersystem for central treatment in the proposed wastewater treatment plant.

6.4.2. POOR INFRASTRUCTURES

There are generally poor infrastructures regarding flood control and sanitation facilities in varioustowns along Three Rivers proposed for integrated environment control. Domestic refuserequires urgent improvement for collection, transport and disposal. Industrial waste water isseldom treated and has a high pollution level. Without due treatment, industrial waste water,agricultural waste water and domestic sewage are discharged into Three Rivers without control.

6.4.3. RIVERS NEED TO BE CONTROLLED

Three Rivers feature seasonal flood, which is caused by the storms and has the sameoccurrence frequency as the storms. Due to the fact that flood-proof capacity for Three Riverscan not resist the flood which may take place every ten years, the Three Rivers basins oftensuffer from flood. According to the statistics from weather forecast stations, 39 floods took placein Tongliang County during the recent 44 years from 1950 to 1993. During the period of gth to10 h, July, 1989, there was 218mm of rainfall in Tongliang County and Bachuan Town wassurrounded by the flood, where 10 streets, 30 enterprises and 6 schools was flooded, 2456rooms, 6.9 hectares of vegetable field and 213.3 hectares of farmland was ruined by flood, andabout 10,000 people suffered from that flood. Also Taohuaxi River and Laixi River have sufferedfrom frequent flood. Since 1949, Taohuaxi River witnessed 4 great floods.

Due to impact from industrial waste water and domestic sewage and undue waste disposal, thesecondary branches to The Yangtze River, located in Three Rivers basins, are full ofcontaminated flow during rainy season and become hotbed of the fly and mosquito. Wastecauses serious organic pollution in river water bodies and terrible odor, and makes the rivers fullof floating and foam. Thus the city appearance and people's mental and physical health areseriously deteriorated.

Therefore, it is urgent to improve the weakness of current infrastructure in those towns and tocontrol the environment pollution in Three Rivers basins, which otherwise can not provides solidfoundation for urbanization. For this reason, the proposed sites for sanitation also benefit anintegrated approach and include a river embankment program, which components areaddressed in the Sector Specific EA on River Embankments.

6.4.4. ENVIRONMENT CONDITIONS FOR INTEGRATED RIVER CONTROL

From macro point of view, Chinese government introduces the strategies of great developmentof the West, improvement of urbanization, strengthening of ecological environment constructionand ecological reservation upstream The Yangtze River, which provides internal beneficialconditions. Based on analysis of local resources, position and economy advantages sinceChongqin, b-came the 4th municipality directly under Central Government, the World L.ai,.decides to make an investment in this key area of great development of the West. Therefore,this investment not only helps Chongqing improve environmental infrastructure and promoteslocal economy, but also establishes a friendly statue of the World Bank as a constant helper fordeveloping countries and areas while at the same time benefiting the World Bank by return ofthe investment.

From the point view of Three Rivers basins, the local governments fully realize the importance ofenvironmental infrastructure construction. Poor environment means weak urbanization andunsustainable development. Therefore, the local governments pay much attentions on the

SCGR4AH - BYYN - N°2 35 0032 1 R31- AL -- 2004 PA-- 38



proposed integrated river control in their respective development plans and give them the prioritywith respect to allocation of finance resource.

In some areas adjacent to the towns, the riverfront has already been treated and certain resultsand experience are made.

In addition, Three Rivers are considered Mother River for the local people. The integrated rivercontrol will be good for their essential interests and therefore gain general support from them.

The construction materials to be used in integrated river control projects are available in therelated countries and district, which reduces the intermediate links of transportation andmanagement and therefore makes the project cost controlled in a reasonable way.

7. IMPACT ASSESSMENT & MITIGATION

7.1. GENERAL

This chapter discusses the impact of the proposed sanitation sub-components of theCUEP 1 Loan Savings on the physical and human environment. Topics covered include:

* Impacts on the surface water environment;

* Impacts on air quality;

* Impacts of noise;

* Impacts of solid waste;

* Impacts on ecological resources;

• Social Impacts including land acquisition and resettlement;

• Economic Impacts; and

n Accidental Impacts.

The overall impact of CUEP 1 New Components on the environment will be highly beneficial,particularly on the improvement of the river water quality and on the public health. It is notanticipated that the implementation of the project will involve unmanageable negative impacts.

The proposed wastewater components will have many positive effects, most notably:

* Improve water quality of the Bachuan, Huaiyuan, Laixi and Taohuachi rivers and eventuallyof the aquatic ecological environment of the Three Gorges Reservoir.

* Enhance urban construction level of Chongqing Municipality, reduce impact of untreatedwastewater on drinking water sources and improve urban landscape.

• Improve urban sanitary conditions and enhance public health level.

Prediction and analysis of future water quality conditions in the rivers where treated effluent willbe discharged are presented in this section. Odor and noise pollution from wastewater treatmentplants, pump station and sludge management are also assessed in the report, using standardair dispersion model.

Construction activities for wastewater treatment plants, pump stations and pipe network maycause noise, dust, fumes emission, nuisance for the residents, traffic jam, temporary cut-offwater and .cs bUpi;1. These issues are tempnrc.. only and their impact can be sig '; -intlyminimized or by appropriate construction management practices and appropriate constfuctionmonitoring. For all these issues. mitigation measures are proposed and developed further in thisreport (see chapter on Environmental Management Plan).

7.2. POTENTIAL IMPACTS & MITIGATION DUE TO PRCOJECT LOCATION

7.2.1. PERMANENT LAND OCCUPATION AND RESETTLEMENT

In general the potential impacts of land acquisition for the Chongqing Environment Project aremainly imposed on the adjacent towns and rural inhabitants due to the land use by sewagetreatment plants, pipes and embankments. As occupied is a part of flood land whose actual useis restricted to a certain extent, involvement of housings which have to be relocated or tillablefields which have to be occupied is relatively low, the apparent impacts mainly happen during theconstruction period. After the construction, as the river banks are renovated, slope protectionsand embankment protections have been built, control of soil erosion and enforcement of floodprotection are ensured, and valuable land is readily available for greening and construction oftowns while the land acquired or occupied during the construction period will have a higheradded value after the construction of the projects.

According to following Tables, the proposed integrated environmental control for Three Riverneed 115.9 hectares land in total, of which 53.87 hectares for Bachuan River and HuaiyuanRiver for sewage water treatment plant and riverway control; 21.83 hectares for Laixi River forsewage water treatment plant and dikes control; 40.2 hectares for Taohuaxi River for dike andriverway control, and sewage interception pipework.

In Tongliang County, 4015m 2 cf residence house will be relocated, of which 3468m2 of farminghouse and 547m2 of enterprises and organization house. 88 persons will be subject to houserelocation, of which 14 persons are farmers. 211 farmers need for resettlement due to landoccupation. A little of scattered fruit trees, outbuilding or special farming facilities of the farmersare also in the range of land occupation. In Mingguang Village, Xingguang Village, YujiangVillage, Longdong Village and Puan Village of Dazu County, there are 21.83 hectares of landsubject to occupation and 2071 persons subject to resettlement in total. In 10 villages underDuzhou Town and Fongchen Town of Changshou District, there are 422 persons (including 413farmers) in 106 families to become immigrants, 14210.64m2 of housing area to be relocated and17.7 hectares of farmland to be occupied.

The land occupation by the proposed projects has insignificant impact on the short-termeconomic income. With reasonable compensation for land occupation and relocation and alsovarious beneficial conditions and funds provided for immigrants resettlement, the immigrants willhave no problems to make a living. According to analysis, 23.987 million RMB is needed tocompensate land occupation and relocation, of which 6.5191 million RMB for Bachuan River andHuaiyuan River Integrated Environmental Control, .5.69279 million RMB for Laixi River and11.7752 million RMB for Taohuaxi River.

The construction of proposed projects will improve urban environmrental infrastructure andpromote urbanization processes and development of agriculture industrialization in proposedarea, which brings new job and development opportunity for the people and improves stably theliving standards of the immigrants.

7.2.2.1. MATHEMATICAL MODEL FOR SECONDARY RIV/ERS

The proposed projects involve three secondary rivers with flow less than 15m3 /s, which areregarded as small rivers. Therefore, this assessment adopts one-dimensional stable river qualitymodel from water quality management information system, one of results from National"Seventh-Five-Year-Plan" on major scientific and technical research, to stimulate, estimate andcalculate impermanent pollutants. The estimation formula of model with respect to evaluationfactors BOD5, NH3-H and COD is as follows:

LBOD=LBODO (-(K1+K2) t)

NH3-N = (NH3 -N)o exp (-Kn t)

LcoD=LcoDo (-KCOD t)

where

LCOD LBOD and NH3 -N respectively mean concentration of COD, BOD and NH3-N X meters frominitial section, measured by mg/L;

LcODo, LBODO and (NH3-N)o respectively mean concentration of COD, BOD and NH3 -N at initialsection of evaluated river, measured by mg/L;

SG2R_.1,- BfsyM -N0'23..32 R . PA- 42



Expression of t=x/u means flowing time of river, measured by second (s); x refers to longitudinalcoordinate distance of river, measured by meter (m); u means average flowing speed, measuredby m/s.

KCOD means comprehensive attenuation coefficient of COD, K, means attenuation coefficient ofBOD5, K2 means coefficient of recovered oxygen, KN means attenuation coefficient of NH3-N, allof them expressed by l/d. During estimation, the values can be determined by Two-point Methodor be taken with safety margin based on experience with consideration of river featuring shallowand small flow amount water.

For permanent pollutants, zero-dimensional totally mixed model is used for calculation.

7.2.2.2. TwO-DIMENSIONAL STABLE MIXING MODEL

For river section adjacent to confluence where the secondary rivers join the Yangtze River or theJialin River, it shall adopt the common mathematic model and suggestion for river, which arestipulated in EAI Technical Guideline on Surface Water Environment (HJ/T 2.3-93). Forestimation of surface environment impact in this project, it shall combine both two-dimensionalstable mixing accumulative flow model for mixing process in winding river section with effluentdischarged from banks and totally mixed model for fully mixed section. They are respectivelydescribed as follows:1. Permanent pollutants

where

- x means distance from confluence of secondary river to the river section planned forestimation, measured by mi;

- q means accumulative flow, measured by m3/s; q=Huy, where H means water depth,measured by m; u means flowing speed, measure by m/s; y means distance fromestimation point to the bank on the side of confluence, measured by m);

e Selection of data with respect to hydrology and hydraulics

Based on statistic information from Chuntang Hydrologic Station on Yangtze River and BeibeiHydrologic Station on Jialin River for many years, there is usually 1 to 3 months of low waterperiod in Chongqing area. During March 1987, as a typical example for low water period, theextremely minimum flow of Yangtze River is 2060m /s (on April 1, 1973) and Jialing River244m3/s (on March 3, 1973). Thus 98% is taken as assured minimum flow. Therefore, 1816m3/sis taken as upstream Yangtze River on Luxian Country flow during typical low water period and2063m3/s as Changshou section of Yangtze River flow during typical low water period. Based on11102 m3/s of average Yangtze Rive flow for 38 years (from 1950 to 1987), the flow rate isestimated with safe margin and used in this evaluation as flow rate during high water.

The transversal mixing coefficient My is calculated with Taylor method:

My=(0.058H+0.0065B)u..u.= gHJ

where

- My means transversal mixing coefficient. measured by m2/s;

- H means water depth, measured by meter;

- B means river width, measured by meter;

- u. means shearing flowing speed, measured by m/s.

- I means water slope;

- g is 9.81m/s2 .

After the water builds up in the Three Georges reservoir area, the upstream backwater comes toHuahongbao, Jiangjin Country (for Yangtze River) and Maliuping, Hechuan Country (for JialinRiver). When reservoir water level for Gezhouba Dam during low water period is 175m, underthe preconditions where output flow from Gezhouba Dam keeps 5683m3/s and flow rate on theChuntang section of Yangtze River keeps 5,000m3/s, the change of hydraulics data of Chuntangsection of Yangtze Rive is shown in following Table. From that table, it is observed that thediluting and self-cleaning capability are reduced with less flow rate, water slope and transversalmixing coefficient.

For Luxian section where Laixi River joins Yangtze River and Changshou section whereTaohuaxi River joins Yangtze River, the transversal mixing coefficient for Chuntang Section canbe used for calculation because the variation thereof is very limited.

This change in transversal mixing capacity due to the TGD through its backwater effect will befully considered when assessing the impact of the project during the operation period of thewastewater treatment plants.

7.3. IMPACTS & MITIGATION DURING CONSTRUCTION AND OPERATION

7.3.1. IMPACT ON WATER QUALITY

7.3.1.1. IMPACT DURING CONSTRUCTION

The most important impact on water quality will result from activities for the construction of riverembankments. In particular, river dredging will increase the SS concentrations in localwatercourse under construction up to approx. 500mg/L and even more. However, the water willprobably return to its original SS condition after 3 to 5km of natural settlement.

Along Laixi River are located urban water sources for Longshui Town, Fulong Town and MituoTown. The existing water supply plants are also capable to clarify and remove SS. Due to thefact that watercourse control and dike project only make SS treatment load increased duringshort period, the water supply therefore will not be affected. On the contrary, with the laying ofinterception pipework and control along the rivers, the water source quality will become better,which consequentially allows better water for water supply plant.

Mitigation Measures: During Construction, some quantities of wastewater will be generated byaggregate washing, construction activities and labor camps. After settlement pond treatment,aggregate washing water will be used as mixing water to prepare mortar for masonry works.Pollution load of effluents from construction sites will be reduced by appropriate practicesparticularly during refueling and maintenance of trucks and heavy machinery. Pollution fromlabor camps will be controlled through appropriate sanitation facilities as Ventilated ImprovedLatrines or septic tanks. A minimum of one toilet facility for 20 workers will be required.

v.2.1.2. IMPACT DURING rPrFATC.

It is estimated that after implementation of integrated environmental control for Bachuan Riverand Huaiyuan River, the effluents from sewage treatment plant comply with the Grade IlIl ofwater body standards with respect to COD, BOD5 and total P. The only exception is NH3-Nduring the low water period where the maximum concentration is 1.4 times more than standardvalue. It is suggested that the denitrification capacity on sewage in the proposed project be sodesigned that NH 3-N concentrations in effluents over 120C during low water period is not morethan 1 Omg/l and the corresponding indicators comply with the standards.

After implementation of integrated environmental control for Laixi River, due to sewageinterception and treE-. rient along Longshui Town, Fulong Towr and Mituo Town, the waterquality of Laixi River wiii be significantly improved. The current urcw'alifiecd COD and NH3-N insection of Huilongwang, on entry of Yutang Reservoir which is located downstream of thosetown and acts as water supply resource, will comply with Grade IlIl of water body standard.

Changes in pollutant load to concerned river sections are presented in the following table.

The change of water quality of considered sections of Three Rivers, before and after theimplementation of proposed project, is shown in following Table with respect to COD, BOD,NH3-N and Total P.

The implementation of proposed wastewater project will improve water quality of Three Rivers insome degree. However, without significant control of pollution source of industrial wastewaterfrom both banks along Three Rivers, and with serious pollution resulting from agriculturalirrigation return flow in related basins, COD is beyond the standard value in general and NH3-Nand Total P for Huaiyuan River and Total P for Taohuaxi River are also beyond the standardvalues. Therefore, the control of pollution source of industrial waster water shall be integratedinto the proposed project in order that the related water bodies meet the requirements ofenvironmental function.

CHONGQING MUNICIPALITY- THE WORLD BANK


Mitigation during Operation stage: the sewage treatment plants will adopt Oxidation Ditchmethod to treat the intercepted sewage from towns and the effluents will comply with B, Class Iof aquatic pollutant standards as stipulated in "Pollutant Discharge Standards for MunicipalSewage Treatment Plant" (GB18918-2002). Effluents will receive tertiary disinfection beforebeing discharged in the river stream and will comply with standards for discharge afterdisinfection treatment. For each sewage treatment plant, the feasibility study analyzes andcompares the possible disinfection method of ultraviolet light disinfection, chlorine dioxidedisinfection and liquid chlorine disinfection. It is suggested to adopt the same disinfectionmethod for the various sewage treatment plants. The small amount of domestic sewagegenerated in the dining room of sewage treatment plant will be treated inside plant and complywith standard for discharge.

To avoid the pollution risk resulting from overload or brake down of the treatment process, it isconsidered the supply of emergency power facility and spare pumps in each WWTP.

7.3.1.3. IMPACT ON LOCAL WATER UIJALJTY OF YANGTZE RIVER

Bachuan River joins Huaiyuan River and the latter joins Xiaoanxi River in Heitan Town,Tongliang County, which flows north and joins Fujiang River and Jialin River in Hechuan City.Both Laixi River and Taohuaxi River directly join the Yangtze River. For the flow direction ofThree River, please refer to Attached Drawing 1. After implementation of proposed project,COD, BOD 5 and NH3 in water flowed into the Yangtze River will be reduced by 6,939tVa, 3,001Vtaand 637tVa respectively. In local sections of the Yangtze River which suffers from pollutants fromThree Rivers at present, the water quality of surface water will be therefore slightly improved.For example, COD impact during low water period is reduced by approx. 0.12mg/L in average.Since current COD in related sections of Yangtze River meets Grade IlIl of water bodystandards, the implementation of proposed project will reduce the failure of conformance ofcurrent coliform group (1- 12 times more than standard value) in some degree. Combined withgeneral control of domestic sewage along rivers, the problem of Coliform group will beessentially controlled and improved.

7.3.2. !MPACTS ON AIR QUALITY

7.3.2.1. IMPACTS DURING CONSTRUCTION

The main pollution sources are machines burning fuel for digging, transportation, load, unload,vibration. Dust and waste gas from these machines affects air quality surrounding work place.Area most affected is located in a range of around 100 m all around project sites, but also mainaccess roads to sites w; iich wv'l be supporting the heavy truck tralFic.

Also, same impacts will be observed along the network rehabilitation or extension sites, wherethe impact may be more direct for the population than the one from the WWTP sites, as theresident population will be located much closer to works, but should have a shorter duration asthe work sites move permanently.

According to field monitoring of dust generation on various construction sites, the dustconcentrations on the places 50m, 100m and 150m leeward to the construction site are 486.5,390 cnd 322prm/m 3 where 2.4m/s of wind i - 3 16.7im/m3 of TSP concc orreference point windward to construction sit_ and 599,5pm/m3 of TSP concentrations withinconstruction site. Thus it is seen that the effected scope of dust generation within constructionsite is approx. 150m. Additionally, the construction equipment features small amount of emissionand short period of application. In Chongqing the air humidity is great, wind speed low and watercontent of soil high. It is available for water spray on specific points on construction site duringdry season and coverage of earth and stone transported. Therefore the emission and dust fromconstruction and transport can be effectively controlled with respect to impact degree andeffected area. The construction applies a little impact on ambient air.

nv .- 3-, -~2. 47



Part of the spoil obtained during the WWTP construction should be reused to fill ground. Duringpipe network implantation, spoil will be stockpiled or reused to fill ground. During projectconstruction and especially during transportation and disposal of this spoil, there could beimpacts on the environment. Spoil dropped on the ground by vehicles and spoil on the vehiclewheels would generate dust clouds on fine days, and would make the road muddy on wet days,affecting both people and passing vehicles as well as the local environment.

If the spoil is not properly disposed of or stockpiled, it would impact the cleanliness of the city. Ifexcavated spoil is stockpiled for several weeks, the spoil will be dried by exposure to sunlightand wind and when disturbed, will raise dust clouds resulting in an increase in the fine particulatecontent of the ambient air. Hence, management of spoil during the c.onstruction should bereinforced to prevent excessive impact on air quality by reducing the emission of dust.

However, most of this impact will result from the simultaneous creation of river embankmentwith important earthworks.

Mitigation measures: Mitigation concerns mainly appropriate construction and earthworksmanagement methods to be imposed to the Contractor:

* During excavation/filling earthworks, water will be sprayed to keep certain humidity;construction site and worker camps as well as other project areas soil surface will beregularly sprayed during dry periods to prevent dust emission;

* Disposal sites for excavated material will be compacted and sprayed with water regularly;spoil not used on site will be removed at the soonest for eventual disposal outsideurbanized areas;

3 Inflammable construction waste (cartoon, paper, plastic, wood, etc.) will not be burned onsite but transported to appropriate landfill or disposal site;

Cooking for workers on sites will rely on gas or electrical cookers, and will not use charcoalor wood or any product generating dust or fumes:

a Trucks for spoil transportation will be covered before they leave the construction sites tolimit dust emission during travel to disposal site; washing stations will be installed in mainconstruction sites (WWTP) to avoid release of mud on public streets and roads witheventual production of dust (or sediment to sewers);

* Strict maintenance of engines for trucks and other heavy machinery will be implemented bythe contractor to reduce smoke and gas emission;

* Roads for truck traffic will be selected preferentially outside residential areas.

7.3.2.2. jDiPrTS DURING OPERATION

Major sources of odor are the aeration tank, sedimentation tank, sludge condensation tank,sludge dewatering zone, etc. Odor sources are all non point pollution sources.

Standards used for evaluation are presented in the following table.

Sewage treatment plants will adopt an oxidation ditch process, which produces low level of odor,and provide 100 m of sanitary protection distance. According to comparison analysis for fieldsmell in sewage treatment with general aeration method, the odor concentration 1 OOm away cancomply with the related standards and should not cause unpleasant impact on the people livingin surrounding residential areas. Tongliang station presents more risk of nuisance due to thevicinity of residential areas.

During operation, sewers and pump stations generally do not emit odor pollutants, if they areappropriately operated. Pump stations may possibly release some odors, but impact is uncertainas they are located far from the nearest residential area. Therefore no significant impact fromodor pollutants of pump stations is expected.

Mitigation: during operation, the bar screen well and screened slag packing will be located anddone inside house of sewage treatment plant. Common ventilation system will be provided tovent odorous gas from high level. Good maintenance and operation of the treatment process willbe necessary to limit the emission of odors from the system. Planting separation strip and 100mbuffer zone will minimize risk of unpleasant smell for nearest residents.

At night, especially, construction noise would impose a severe nuisance on the residents in thevicinity, especially those located at less than 50 m. Night working and especially the use of themost noisy equipment during the night should then be strictly controlled in order to minimize theimpact of noise on the surrounding residents. In particular for excavations, drills used outside atthe beginning of tunnel construction should be forbidden at night. In order to limit constructionnoise to people, China government issued a regulation "Noise limitation of Construction FieldBoundary (GB12523-90)

Based on the daytime and ri:yht time limiting noise values contained in this regulation, the bufferzones required to respect these limiting values have been calculated and are presented below.

Vibrator 80 4 18

Drill 105 100 Prohibited

Mitigation: During construction, contractors will be requested to use low noise heavy equipmentwhich comply with standards. Use of noisy equipment will be forbidden during the period from 10p.m. to 6 a.m. Night working and especially the use of the most noisy equipment during the nightshould then be strctly controlled in order to minimize the impact of noise on the surroundingresidents. In particular for excavations, drills used outside at the beginning of tunnel constructionshould be forbidden at night. In order to limit construction noise to people, China govemmentissued a regulation "Noise limitation of Construction Field Boundary (GB12523-90) ".

Use of explosive during nighttime is prohibited. The amount of explosive shall be controlled andmicro-deviation explosion technique shall be adopted to reduce the impact of explosion noiseand oscillation on residents, environmental protection targets and environmental susceptiblespots. Construction activity during nighttime is also prohibited during the period of importantschool examination. For the residents or organizations who suffer from construction impact onlocal section, the construction units and supervision units shall strengthen coordination or makedue compensation where necessary.

7.3.3.2. IMPACTS DURING OPERATION

During the operation phase, the main sources of noise are due to pumping stations and wastewater treatment works with equipment such as pumps, ventilator and air compressors with noiseproduction in the range 86-95 dB(A).

Standards applicable to Level 2 areas (residential) are 6OdB(A) during day time and 5OdB(A)during night time. Taking into consideration the distance to nearest residential buildings inTongliang, these standards should be respected.

Mitigation: During Operation stage, the main noise sources of sewage treatment plant consistof sewage pumps, sludge pump and sludge demisters. The sewage pumps and sludgedemisters shall be accommodated inside the pump station to reduce oscillation and insulatenoise. The water outlet shall be treated with flexible connectors. The sludge pumps shall be ofsinking pumps and the surface aerators of low noise type ones. Combined with reasonableprocess layout and 5-20m planting insulation strip and approx. 100m buffer zone to residentialareas, environmental noise level during operation will comply with the related standards.

Transport vehicles (based on 5t of capacity per vehicle) to carry sludge and small amount of rawmaterials should increase to maximum 15 vehicle per day and will only operate daytime.

7.3.4. IEMPORARY LAND ACQUISITION DURING CONSTRUCTION

For the WWTP, it is not anticipated the temporary acquisition of land during construction.Storage of equipment, work sites and worker camps should be organized within the landallocated to the plant.

For sewer laying works and pumping stations, some temporary occupation of land may berequired. Most of the time it will be in a public area (road for example). However, in case

SOGREAH - BVN - N°2 35 0032 ' R3.1- A 01 2UO4 PAGE 50




temporary use of land may result in the alteration of previous use or agricultural production, theloss for the previous user will be fully and fairly compensated during the period of occupation bythe project.

7.3.5. IMPACT ON NATURAL AND ECOLOGICAL ENVIRONMENT

The project will not involve any destruction of valuable natural land. Site in Tongliang is totallydeveloped, site in Longshui is agriculture land. Both sites have no particular ecological value.

The development of the sewer network may impose the cutting of street trees. This impact canhardly be quantified at present, but during works, field inspectors in charge of supervising theEMP will ensure that any tree is cut by absolute necessity, that any cutting is registered and thatthe project will ensure replanting of trees at a rate of not less than one tree planted for one cut.

Regarding aquatic ecology, the baseline survey carried out for the purpose of this study hasdemonstrated the high level of pollution of the river nearby the project sites, with a probablyrelated low biodiversity. The terrestrial/aquatic ecological environments and ecologicalenvironment in towns along rivers are already seriously affected, particularly in the Laixi Rivetand Taohuaxi River which have basically lost their application functions due to pollution fromindustrial and domestic wastewater, disposal of refuse and serious soil erosion. The problemsinclude silt-up of watercourse, eutrophication of water bodies, floating of algae, abnormal watercolor and bad smell.

Mitigation: with measures imposed to the contractor to control river pollution from constructionsites, significant impact of construction on the aquatic environment is not anticipated.

Impact during operation will be globally beneficial, as a direct consequence from pollutiondischarge abatement.

7.3.6. CONSTRUCTION WASTE MANAGEMENT

Significant volumes of spoil will be generated during the construction of the project components,mainly composed of earth from excavation works and not re-used for filling or reclamation, andof the products from demolition of existing buildings and concrete structures, mainly along thesewer network component.

Earth spoil will need to be removed from the construction sites using trucks, with resultingnuisance for residents and public safety issues related to the risk of traffic accident. Strictprocedures related to this activity will need to be imposed to the contractor in charge.

TOTAL 2,993,000 2,722,000 + 271,000

In order to ensure minimization of nuisance from inadequate management of constructionwaste, the contractor in charge of civil works in each site will prepare and submit a spoilmanagement plan which will respect the following guidelines:

SOGREAH - BYN - N°2 35 00321. R3.1- 20054 PAGE 51

CHONGQING MUNICIPALrTY - THE WORLD BANKCHONGQING URBAN ENVIRONMENT PROJECT - NEW COMPONENTS


1. Present a detailed sheet of expected spoil volumes including:

* Building demolition volumes,

* Earth volumes from excavation works (distinct for WWTP and network),

* Schedule of production.

2. Details the possible volume for reuse of demolition spoil and excavation spoil.

3. Identify and present on a map the areas anticipated for the disposal of excess spoilwhich cannot be reused as fill; provide location of site (on a map), area needed, volumeto be disposed off, land use of area, agreement of owner/user to dispose spoil on thesite.

4. Provide information of access road anticipated to be used: distance, type of road,number of urban/village areas crossed.

5. Soil and spoil removed during the construction process shall be stockpiled separatelyand stabilization measures implemented. The soil shall be used for landscaping andrestoration of work area. The stockpiles shall be constructed with smooth slopes andfree draining patterns. Spoil stockpile will not exceed 3 meters and the slope will not bemore than 2:3.

6. Spoil stockpiles or platforms shall not be located on drainage lines or in floodway zonesor other areas important for the conveyance of floodwaters during major floods.

7. Soil and spoil to be stockpiled for long periods of time shall be stabilized by seeding topromote vegetation growth and reduce surface runoff.

8. Erosion and sedimentation shall be controlled on a round the disposal site during theconstruction stage. Where necessary, sediment traps/basins will be implemented.

9. During the implementation of the works, any requirement for a new disposal area forspoil will be subject to the preparation of a similar management plan.

Spoil management plan will be prepared by the Contractor not later than 30 days before the startof the works in the considered area.

7.3.7. OFF-SITE PUBLIC SAFETY AND INCONVENIENCE

Proposed sewer systems or pipe networks will certainly cut across some roads or run parallelwith them. During the excavation and pipe-laying stage, there will be more traffic congestionalong these roads.

The conventional way to solve the problem is to build side-tracks for vehicles duringconstruction. As these temporary roads are usually very narrow, it is impossible for vehicles topass each other. In addition, some vehicles will find it necessary to make a detour, which will notincrease the mileage but also increase the traffic volumes on other roads. During projectsconstruction, spoil encroaching on the road surface will result in narrowing of the carriageway.On dry days, the surface will be dusty and on wet days, the roads will be covered with mud andbecome slippery.

The project will take all the necessary measures in order to minimize the detrimental side effectsof network construction. Coordination between the contractor and the traffic police will minimizeroad blockage or will reduce it to the minimum duration. Pro-active information will also beimplemented in order to have the concerned residents or daily passer-by to be informed of thedate and the duration of the works in their area. This information will be done through posters,

SOGREAH - BYN - N'2 35 0032 1. R3.1- AJG,,ST 20C4 PAGE 52



local meetings and the creation of an internet site dedicated to the project and providing freshand up-dated information on these issues.

The contractor(s) will be required to implement safety and road signs in sufficient quantities and 2at the appropriate location, in order to facilitate traffic diversion and to reduce the risk of jam andcar accident.

7.3.8. IMPACT ON QUALITY OF LIFE

Through integrated environmental control for rivers, the related areas will have better status ofurban environmental infrastructure such as water supply & sanitation, flooding preventioncommunication, improved capacity to control soil erosion and to prevent flooding, and betterecological environment, urban landscape and investment environment. People will live and workin peace and contentment and society will keep stable. The related counties and districts willmodify the urban economy structure and industry structure based on their own specificconditions. The application of proposed projects will promote the infrastructure construction forsewage treatment, refuse disposal and others.

It is believed that implementation of proposed projects will improve the local economy, livingstandard of people, urbanization construction and urban ecological environment protection.

7.3.9. SLUDGE MANAGEMENT

7.3.9.1. ESTIMATED SLUDGE PRODUCTION

Wastewater projects have definitely a huge beneficial impact on urban environment, butwastewater treatment means also sludge production, with a high risk to concentrate and releasepollution if the sludge produced are not appropriately collected and safely disposed. Solutionshave to be found to minimize the amount of sludge produced and to implement safe disposalfacilities.

After the implementation of proposed project, the dry sludge produced by the two WWTP ofTongliang and Longshui will be 5,256 tVyear (6.6 t/day BOD5 and 7.8 t/day SS), each stationcontributing to 50% of this total or 2,628 t/year. The initial water content of sludge straight fromthe sewage treatment process may reach 98% to 99%. To allow for easy and economicalhandling, dewatering operation through belt press will be carried out. This should allow thereduction of water in the sludge to a level around 80%, sometimes even less. The sludge andscreenings will thus be transported by trucks to dedicated landfills for disposal.

TABLE 28. EXPECTED SLUDGE PRODUCTION

WWTP Capacity in 2005 Dry Sludge Dry Solid Content Wet sludge(m /d) production (tons/y) (%) production (tons/y)

According to this table, the total of sludge produced daily by each of the WWTP will be36 tons/day of sludge at 20% dry solid.

In addition to the sludge, the volume of solid waste from screen bars will also need handling,transportation and disposal. The volume is generally at least equivalent to that of the sludge, butwith a solid content of 40%.

The table shows that about 108 tons/day of wet waste will need to be evacuated from both newWWTP. Wet sludge alone will represent 72 tons/day.

7.3.9.2. SLUDGE COMPOSITION

In Tongliang WVWTP, heavy metal content of sludge is expected to be low, as a special WWTPdedicated to industrial parks will be constructed. The Tongliang station will thus receive mainlydomestic water. The Longshui WWTP will receive part of industrial effluents, and a higher heavymetal content may be expected in the sludge. However, it may be reasonably expected aprogressive reduction in heavy metal contamination of sludge in the coming years as the resultof the implementation of the national clean industry strategy, which promotes industrial wastewater treatment facilities and clean industrial processes with higher recycling level of effluentsand waste. During future operation, industries discharging to the wastewater network should bestrictly controlled for ensuring that the industrial discharges to the wastewater networks do notexceed the allowed concentrations and loading rates (generally based on national standards asdescribed in Appendix 3).

However, like the other small and medium-sized (< 50,000 m3/d) sewage treatment plants inChina, the sludge recently produced from proposed projects is not planned to be digest-treated.Such sludge has unstable performance and contains degradable organic matters which arelikely start fermentation and generate smells. Additionally the low abatement ratio for pathogenicbacteria and helminthes egg make the sludge dangerous for public health and not suitable foragricultural application. Therefore, the sludge produced is proposed for disposal in appropriatelandfills.

7.3.9.3. TREATMENT AND DISPOSAL OF SLUDGE

The sludge to be produced will be stabilized. After stabilization and thickening, sludge will bedumped in dedicated landfills. Two landfills are considered to accommodate the sludgeproduced by the two WVWTP components (Tongliang and Dazu). In Changshou, a new landfill isin operation since the first quarter of 2004 to accommodate the sludge produced by the existingWWTP.

Sanitary Landfill Design - Tongliang & Dazu

Refuse is mechanically collected and transported in enclosed containers, which therefore avoidssludge leakage and flying. Management on refuse collection and transport is also improved toreduce noise impact. Bag filter is provided in refuse sorting shop to control dust emission.

The leachate and gas generated in landfill are guided out of landfill in a safe, reliable andapplicable way.

Sanitary landfill is provided with the combined anti-seeping measures in both vertical andhorizontal directions so as to prevent pollution on surface water and ground water from leaching.For leachate treatment, the proven recycling backfill process is proposed, by which the finaltreatment quantities and initial treatment concentration of filtrate can be reduced during practicaloperation. There is a reinforced concrete structure of leachate adjusting basin located between

main dam and intercepting dam. With large buffer capacity, the leachate-adjusting basin has themain functions to store water and to adjust influent water quality and volume for leachatetreatment station. Calculated on month-to-month balance of average historical rainfall and max.seeping amount, and checked against its occurrence once every 20 years, the basin is found bigenough to hold leachate from sanitary landfili for 30 consecutive days. With proven treatment --

process, the effluent from leachate treatment station shall meet the standard of discharge.

Daily dirt coverage unit by unit is applied for sanitary landfill to control efficiently odorous gasgenerated. Pollution control of odorous gases (such as sulfured hydrogen and ammonia) andsafe combustion and emission of waste gas containing firedamp are combined to make thosegases up to standards of environment impact concentration and site concentration. Carbondioxide converted from gas combustion byproduct shall meet the standards of emission andenvironmental quality.

For sanitary landfill, the refuse dam, intercepting dam, various sub-dams, flood intercepting ditch(pipe) and land excavation yard shall be designed in accordance with applicable nationalstandards and codes, minimizing soil erosion and ensuring safe operation in sanitary landfill.Improved equipment management and maintenance of combustion tower and leachatetreatment station can minimize off gas pollution risk and emergency emission. Provision of 500msafe protection interval can reduce adverse influence on social environment in neighboringcommunity as much as possible, and make it compliant with pollution control standards onrefuse burial.

Taiping sanitary Landfill - Tongliang

The stabilized sludge from the Tongliang Wastewater Treatment Plant will be disposed at aplanned sanitary landfill located northeast of Taiping Town, about 10km away from the centre ofTongliang County. The disposal capacity of the landfill is 250tVd. Construction is planned to startin August 2004, and is expected to be put into operation by the end of 2005. It will match theimplementation of the wastewater treatment plant to accommodate sludge produced as soon asthe plant operation starts.

Construction started on December 28, 2003, and ground leveling, supply ofwater & power and approaching road have been finished. It is expected to be put into operationby June 2005. It will match the construction and operation of wastewater treatment plant ofintegrated environmental control of Laixi River Project.

Ximajiagou Landfill - Changshou

For Changshou, where there is an existing wastewater treatment plant, sewage sludge iscurrently co-disposed with household refuse in an existing newly constructed sanitary landfill.located on Ximajiagou, Yangjia Town, Changshou District, 10km away from Fenchen Town(capital of Changshou District). The landfill was constructed in 2003 and was put into operationin 2004, with a total investment of 75.76 million RMB. The landfill is designed to treat waste at300Vtd and operate for 28 years, serving 7 towns (including Taohua area of Changshou District),and 280,000 populations in the near future and 450,000 populations in 2030.

7.4.4. RISK RELATED TO SLUDGE MANAGEMENT

As already mentioned, the present project should ensure appropriate handling and disposal ofsludge in the dedicated landfills. However, inappropriate management of the landfill may result inthe eventual pollution of aquifers and of drainage rivers.

SCGREAH - BYN - N°2 35 0032'. R3.1-A_&S- 2CC4 PAGE 57



7.4. ENVIRONMENTAL RISK ANALYSIS

7.4.1. OVERFLOW AND ACCIDENTAL SPILLAGE

The occurrence of an overflow (during a rain event) or a major break-down in the operation ofthe VVWTP may result in the temporary release of untreated wastewater in the river. An increasein organic pollution downstream may thus be anticipated.

EA estimates the environment risks in case of these two kinds of emergency discharge wheresewage treatment is reduced to 50% and 0% (without any treatment) before sewage isdischarged into Bachuan River and Huaiyuan River, with the following results: when sewagetreatment is reduced to 50% due to failure, the BOD5, NH3-N and total P in the ground waterwithin 5 km from discharge point of effluent of sewage treatment plant for Huaiyuan River will be1.86 times of the standard values. When sewage treatment is reduced to 0%, the COD, BOD5,NH3-N and total P will be 2.70 times of the standard values.

Due to the rare possibility where two or even all of the three sewage treatment plants for LaixiRiver fail at ttie same time, only one plant, which serves Longshui Town and is most closed(approx. 5km) to Yutang Reservoir downstream, is considered for environmental risk due toemergency discharge. The analysis shows that in case domestic sewage is only primary treated(grid and settlement) in sewage treatment plant serving Longshui Town before discharge, themaximum COD, BOD5, and NH3-N in the ground water in section of Huilongwang, HuaiyuanRiver will be 1.60 times of the standard values.

To minimize risks, emergency power facility and spare pumps are considered in the design forsewage treatment plant. Strict operation regulation and careful equipment maintenance must befollowed and performed so as to minimize or even eliminate any abnormal working status. Therelated environmental authorities shall strength the policy instruction and supervision on sewagetreatment plant and help the latter minimize any possible occurrence of pollution accident so asto reduce environmental risk.

7.4.2. DEVELOPMENT PLANNING

This risk threatens the global objective of the project to improve the quality of the rivers and ofthe Three Gorges Reservoir. Indeed, the present subprojects supported by the WB are only partof a much larger program which concerns other major cities and as demonstrated with the far-field water quality modeling, this river improvement can only be obtained if those othermunicipalities manage their wastewaters.

Thus the planning risk is the delay or the cancellation of VvWTP in other PRD urban areas.

7.4.3. THREAT FROM INDUSTRIAL ACTIVITIES

As the WWTP will receive part of industrial wastewater, there is still a risk that the release ofexplosive or toxic products in the sewers affect the plant operation. However, strict regulationsdo exist in Chongqina Municipa'lty related to the discharge of industrial effluents into the urbansewers, and the authorities are implementing a strong policy for the enforcement of theseregulations and on the treatment of industrial effluents which should, in the near future, stronglyreduce the risk.

8.3. MITIGATION PROGRAM

Mitigation requirements and measures identified during the Environmental Assessment studiesof the sub-projects mainly concern the following issues:

* The compensation for temporary or permanent land acquisition, with resettlement programif involuntary displacement of persons,

* Mitigation for the loss of valuable ecological or cultural resources.

* Application of environmental good practices during construction activities by theContractors on all the construction sites and in their surroundings.

S0GREAH -BYN - N°2 35 CQ32 1. P3 1-A,- 21004 PAGE 62




8.4. MONITORING PROGRAMS

In order to ensure the strict and efficient implementation of the mitigations measures proposed,including the respect of environmental obligations during the construction stage, a program ofmonitoring activities will be required, which includes mainly 3 types of monitoring:

* The general environmental and social monitoring of construction sites and activities,

* The specific monitoring of water quality and water pollution control,

* The specific monitoring of air quality and pollution control, and of noise.

Monitoring of land acquisition and resettlement is considered in RAP reports and will not bediscussed again as part of the present Consolidated EA Report.

8.4.1. MONITORING OF CONSTRUCTION ACTIVITIES

This monitoring aims at ensuring compliance of Contractor activities with its contractualcommitments as well as with the environmental regulations and standards prevailing in PRC.

Monitoring should be carried out during the project construction stage.

8.4.2. WATER QUALITY MONITORING

Objective of water quality monitoring is to ensure pollution control from construction activities isefficient and that all activities are performed in compliance with applicable standards.

8.4.2.1. LOCATION CF SAMPLING SITES

Sampling sites will be established in critical points where the control of effluents fromconstruction activities can be easily implemented. This concerns for example major drainageoutlets from construction sites, from concrete batching plant (if any), from worker camps, fromspoil disposal areas, from machinery reparation yards or from petrol products storage areas.

8.4.2.2. PARAMETERS TO BE MEASURED

The most frequently observed pollution types from construction works are mainly suspendedsolids due to earthworks, soda effluents from batching and concrete related activities, andhydrocarbons from engine leakage and maintenance. Potential pollution from labor camps ismainly of bacteriological nature and related to sanitation issues. The parameters to be followedmust be the best indicators of activities anticipated in the sites, which may clearly establish thepresence or not of a nuisance directly induced by the activities. The other types of parametersconcern those providing a more general information on the condition of the receiving river. Theparameters are:

* At any discharge point from the construction sites: Temperature, pH, Electrical Conductivity,Dissolved Oxygen (DO).

* At the treated effluent disc,; arge point from labor camps (if any): Fecal Coliform, Ammonia,Biological Oxygen Demand in 5 days (BOD5).

* At the outlet of concrete production effluent (if any) and of earthworks: Total SuspendedSolids (TSS) and pH

* At the outlet/drains draining construction activities and mechanical maintenance areas: pH,TSS, oils.

SOGREAH - BYN - N°2 35 0032 1. R3 1- .^-S 2004 PAGE 63



When required, monitoring may also include some of the parameters conventionally used forMunicipal or National Monitoring stations: TDS, Chemical Oxygen Demand (COD), Ammonia,Total Nitrogen, Total Phosphorus.

Semi-annual reports of WQM and other monitoring results will be prepared by the Consultant tothe local environment agency, with a copy to the PMO.

8.4.3. AIR QUALITY AND NOISE MONITORING

8.4.3.1. PARAMETERS

Monitoring of air quality and noise will be carried out during construction and operation stages ofthe project. Purpose of monitoring is to ensure that air pollution, dust and noise standards arerespected on the construction sites and that these nuisances are kept at the minimumacceptable level for the surrounding residents.

During construction, monitoring sites will be identified around the concerned sites and nearbysensitive spots located around.

During operation stage of the Longshui and Tongliang WWTP, appropriate parameters (H2S,NH3, S-methanol and total bacteria) will be monitored by the Operator of the facility.

Noise will be monitored in each site located close to residential areas or when required wheresuspicion of excessive noise exists. Noise levels will be monitored over periods of 24 hrsduration inside the construction sites and around.

A special attention will be provided to noise leve&s . ionitoring during night time, around thesewer network working sites and machinery, most being located in residential areas, and nearsensitive spots as schools and hospitals if any.

10. CONCLUSIONS AND RECOMMENDATIONS

10.1. IMPORTANCE OF PROJECT

If all the areas concerned by the Project Components show good environmental conditionsregarding air and noise, all satisfying Level II standards, they also all show heavy water pollutionlevels. On the average, COD in Huaiyuan River is 2.1 times the standard value, and BOD5 1.59times, petroleum 74.4 times, NH3-H 5.82 times, and total P 4.72 times. In Laixi River COD is2.55 times the standard value, petroleum 14.02 times, NH3-H 1.07 times, and total P 1.21 times.In Taohuaxi River COD, BOD5, NH3-H, and total P are all 1.5 to 2 times the standard values.petroleum 10 to 20 times the standard values. Bacteriological pollution (Coliform) in the threerivers exceeds by 100% the standard, and in the worst case 1000 times the standard value.

CUEP wastewater Loan Savings components will strengthen cities environmental protection,protect the Yangtze system water resources and water quality especially for the Three GorgesReservoir on the long term, reduce environmental pollution resulting from wastewater discharge,protect surface water and underground water, improve people's quality of life and public heath.

Improvement of urban environmental quality boosts also city economic development though abetter attractiveness for investors and middle class residents, a raise in land and building valuealong rehabilitated river sides and creeks. Reduction of pollution load to the river results also,further downstream in water quality improvement with beneficial impacts on aquatic biodiversity,fisheries and protection of water resources.

10.2. MAJOR ANTICIPATED IMPACTS AND MEASURES

Sites anticipated for the Wastewater Treatment Plants are appropriately located. Land has beenacquired involving limited expropriation and demolition, which have been compensated. Aminimum distance of 100 m between Tongliang Plant and residential buildings is respectedLongshui WWTP is located in a rural area, with no anticipated nuisance for surroundingpopulation.

Main sewers will be implemented together with river embankment works. Most of the demolitionand resettlement requirements, which are significant, result from the river embankmentcomponents closely associated to the wastewater components.

Phase 1 for Tongliang and Longshui WWTP will provide an additional treatment capacity of60,000 m3 per day, resulting in a total annual river pollution abatement of about 3,100 t BOD 5,6,700 t CODcr, 3,800 t Suspended Solids, 620 t NH3-N and 80 t PO43P.

As a consequence of this positive pollution abatement, both WWTP will generate a total wetwaste quantity of about 108 t/day, including about 72 t/day of wet sludge at 20% solids anaabout 36 tVday of screen bar waste at 40% solids. This wet waste will be safely disposed in twodedicated landfills presently under construction.

The project is not anticipated to involve detrimental impacts on the terrestrial and aquaticecosystems. Sites dedicated to the facilities are already urbanized. Any road tree felled becauseof the sewer laying works will be replanted at the end of the works.

SOGREAH - BYN - N°2 35 0032 1 R3.1- A'L3G- 2004 PAGE

CHONGQING MUNICIPALrTY - THE WORLD BANK


The project is not anticipated to affect any known cultural spot, and definitely not at WVVTP sites.However, excavations in the cities for the sewer network may reveal some buried remains ofhistorical value. Procedures will be set-up for construction.

A major impact during construction may result from the large volumes of earthworks, mainlyrelated to the river embankment works (total of about 3 million m3 excavation and 2.7 million mfill), if not appropriately managed by the contractors: dust, mud, sediment discharge to river,degradation of temporary spoil disposal sites).

At the time of the construction, and particularly for the sewer network components (and mainlyfor the urban river embankments), several construction sites will be implemented over the citiesin densely inhabited areas. Several nuisances and risks for the public safety may result ifappropriate measures are not strictly enforced. For this purpose, the EnvironmentalManagement Plan proposes to implement specific mitigation measures including:

* The implementation of clear procedures for routine monitoring, reporting and addressingnon-compliances detected on the construction sites.

* The implementation of procedures for public information, to deal with nuisances as roadtraffic disturbance, water, electricity or gas temporary cut-off, temporary noise, andincluding among classical information measures the creation of an Internet site dedicated tothe Project.
