GENERAL

Wenchuan Earthquake Recovery Program (WERP)

On May 12, 2008 at 2:28pm, an earthquake of magnitude 8.0 Richter and 11.0 degrees in seismic intensity struck the southwestern part of China, centered in in Sichuan province. As a result of this earthquake and its more than 20,000 significant aftershocks, more than 69,000 people have died, 374,000 have been injured, and 18,000 remain missing. Losses include: 34,000 km of highway destroyed; 1,263 reservoirs damaged; 7,444 schools and 11,028 hospitals and clinics collapsed, and 5.5 million rural houses and 860,000 urban houses destroyed or significantly damaged. Direct losses are estimated at RMB 844 billion (USD 123 billion). Approximately 34 million people live in the affected area, with almost 20 million in the severely affected area.

In response to the earthquake, the World Bank has lend USD 710 million of IBRD financing to the most highly affected provinces of Sichuan and Gansu for post-earthquake reconstruction, that is, the Wenchuan Earthquake Reconstruction Program (WERP).

The expected outcomes of the project are to restore and enhance access to essential public infrastructure and services (e.g., water supply, wastewater and drainage, solid waste, roads) and core health services in affected counties in Sichuan and Gansu prioritizing, where possible, the needs of the poor and/or newly vulnerable arising from the earthquake. In addition, the expected outcomes include the rehabilitation of education facilities and restoration of access to public education in project counties in Gansu. In both provinces, sub-projects will be designed to reduce the vulnerability of the services to seismic and flood hazards.

The proposed WERP is designed to comprise two parts: z Part 1- Sichuan Recovery Program (Bank loan US$510million)

- Infrastructure (Bank loan USD 432.4 million). This component will finance civil works and goods required for the reconstruction and appropriate expansion of infrastructure, in approximately 16 counties in the five municipalities of , , , and Ya’an. In view of the project preparation progress, the component is organised to be implemented in two batches: Batch 1 and Batch 2.

- Health (Bank loan USD 57.6 mil lion) component will finance civil works and goods required for the reconstruction and appropriate expansion of health services, in about 19 counties in the seven municipalities of Mianyang, Guangyuan, Bazhong, Nanchong, Ya’an, and .

- Project support (Bank loan USD 20.0million) will finance training, capacity building and engineering costs of sub-projects. z Part 2 - Gansu Recovery Program (Bank loan US$200.0million)

This will finance infrastructure, health and education sub-projects in 7 counties in Longnan Municipality with a focus on Cheng, Hui, and Xihe Counties.

- Infrastructure (Bank loan USD 130.3 million). This component will finance civil works and goods required for the reconstruction and appropriate expansion of infrastructure.

- Health (Bank loan USD 32.3 million) will finance civil works and goods required for the reconstruction and appropriate expansion of health services.

Sichuan PPMO 1 April 2009 Summary Environmental Impact Assessment for Yuanba Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP) - Education (Bank loan USD 33.4 million) will finance facilities and equipment for the reconstruction and appropriate expansion of primary, secondary, and vocational/technical schools.

- Project support (Bank loan USD 4.0 million) will finance training, capacity Building and engineering costs of sub-projects.

Project Organization

Due to the project urgency, a strong project leading and technical support system is required at all the national, provincial/municipal and county levels to guarantee the quality of project implementation.

At the national level, the National Development and Reform Commission is responsible for the approval of Investment Application Report, and the Ministry of Finance is responsible for the signing of Loan Agreement, the supervision of loan use and the loan repayment.

For the overall project coordination of all the involved Project Implementation Units (PIUs) at the project level, there are totally three project management offices organized under the leadership of the provincial DRC, the provincial financial bureau and the provincial department of construction in the two project provinces (Sichuan and Gansu), respectively:

- The Urban Construction Project Management Office (UCPPMO) and the Health Project Management Office (HPPMO) for Sichuan Components; and

- The Longnan Municipal Project Management Office (LMPMO) for Gansu components.

The general institutional organization of the project implementation can be summarized in the following chart.

Sichuan PPMO 6 April 2009 Summary Environmental Impact Assessment for Yuanba Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP)

Background and Description of Yuanba Subproject

The Chinese EIA documentation for Yuanba subproject under Batch 2, WERP, consists of two EIA reports (respectively for the solid waste and road components) and two EIA forms (respectively for the wastewater and water supply components), which are all prepared by the Environment College of the South-West Jiaotong University (qualified as a Class B EIA consultants in China). The first draft was submitted to Sichuan urban construction PPMO on Nov. 23rd 2009, and the review comment by the DRA consulting team has been delivered to the domestic EIA consultants on Nov. 28 2009. Based on the comments and further project information, the EIA documents of Yuanba subproject have been modified twice and the two revisions were again submitted to Sichuan urban construction PPMO respectively on Dec. 7th and Dec. 11th. Among others, the latest version has been used as the key reference for this summary EIA.

PROJECT BACKGROUND

Yuanba District is one of the highly affected areas in the Wenchuan Earthquake with severe loss, especially in terms of local water supply and drainage facilities, urban roads and bridges, environmental sanitation facilities and mass transit facilities.

For example, Wangjia Town and Hongyan Town respectively in the southeast and west of Yuanba District have greatly suffered from the earthquake with great impacts on the normal operation of the towns and the daily lives of local residents. In Wangjia Town, there are 3323 rural households damaged to different extents, 443 rural houses collapsed or turning into dangerous houses, nearly 80km road damaged with road foundation subsidence and road surface cracking and 25 bridges/culverts collapsed. Even worse, the earthquake has laid almost the whole Hongyan Town flat. According to the statistic data, in Hongyan Town, the earthquake has caused the collapse of 3650m2 local office buildings and 11 rural houses, the serious damage of 408 rural houses and the partial collapse of 196 rural houses. The local power, traffic, communication and hydraulic facilities also suffered greatly from the disaster. The direct and indirect economic loss of Hongyan Town in the earthquake is up to 290million yuan.

On the other hand, the infrastructure of Yuanba District falls short as the local urban construction goes on. For example, currently the whole Yuanba District has only one simple dump site and two solid waste transfer stations for the collection, transportation and disposal of all the domestic solid waste from the urban area of the district. In addition, these facilities have all been damaged to some extent in the earthquake and remain unable for normal use. As for Wangjia Town and Hongyan Town, the infrastructure conditions are even poor: The existing WTPs are poorly equipped with only the simple settling tank, and since the current water treatment capacity could not meet the water demand of the towns, most of their residents have to rely on the groundwater from their own wells; the water distribution network has been worn down by the years without repair, it goes without saying the earthquake damage; there is no wastewater treatment facilities in the two towns, and all the domestic wastewater is randomly discharged without treatment which has resulted in the deterioration of local surface water and groundwater quality.

Generally speaking, the low road grade, poor drainage and serious damage of roads, bridges and culverts have badly impacted the daily lives of local residents and the progress of post-earthquake reconstruction.

DRA CONSULTING TEAM 7 APRIL 2010 Summary Environmental Impact Assessment for Yuanba Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP) In this context, the reconstruction of damaged or absent water supply and wastewater facilities, solid waste collection and disposal facilities, roads and bridges for the urban areas and the towns of Yuanba District has been proposed under this subproject in order to lay a solid foundation for the implementation of other post- earthquake reconstruction projects in Yuanba District.

COMPLIANCE WITH LOCAL PLANNING

As proposed in the “Post-earthquake Reconstruction Implementation Plan for Yuanba District of Guangyuan Municipality”, the post-earthquake reconstruction of Yuanba District will cover 22km of urban roads, 5 bridges, 14 bus stations, the WTPs with treatment capacity of 25000m3/d, 76km of water supply network, one LNG delivering station, 15km of LNG network, the WWTPs with treatment capacity of 15000m3/d, 56km of sewage network, and 80t/d solid waste treatment capacity with the transfer system. All the proposed components of Yuanba subproject have been included in the reconstruction plan; at the same time, they are also compliant with the “Urban Master Plan for Yuanba District of Guangyuan Municipality”.

PROJECT COMPOSITION

The proposed Yuanba subproject consists of four components in the urban area, Wangjia Town and Hongyan Town of Yuanba District, namely solid waste, road, water supply and wastewater treatment. The project details are presented in the table below.

Alternative Analysis

During the project development, various alternatives have been proposed, screened and compared with technical, economic as well as environmental criteria. In terms of the environmental comparison for the alternatives, the primary objective was to identify and adopt options with the least adverse environmental impacts and maximum environmental benefits.

As presented above, this subproject consists of four components; therefore, the alternative analysis for the subproject will accordingly be organized by component. Additionally, in response to the WB requirements, there will be a special section analyzing potential impacts if without the subproject.

WITH AND WITHOUT YUANBA SUBPROJECT

Compared to the "With" project scenario, "Without" the Yuanba subproject the result would be: • Without the solid waste component, the municipal solid waste collection, transfer and the transportation system efficiency would remain low and, community based sanitation and hygiene would continue to be poor, affecting the heath and living environment, as well as the standard of living for the residents. The sanitation conditions would further deteriorate without the project, resulting in increased solid waste volumes due to urban population growth and rising living standards. • Without the road component, the urban roads damaged in the earthquake will remain at a low grade and the local urban road network will remain incomplete, which will affect the daily commuting of local residents and fall short of the local economic development and the efforts to resume the production and lives of earthquake-affected residents; • Without the water supply component, the concerned towns will not meet the future water demand necessary to achieve the social and economic development targets and a part of the population will continue to rely on polluted underground water for drinking. • Without the wastewater component, the increased volumes of untreated domestic and industrial wastewater along with the rapid industrialization, urbanization and population growth in the area, will be discharged to the water receptors directly. The surface water and groundwater quality would continue to deteriorate, threatening drinking water safety, groundwater quality, local ecosystem, agricultural production relying on irrigation, and thus the living standard of the residents in the project areas and those downstream, and eventually weakening the ability for sustainable economic development in the district.

SOLID WASTE

For the proposed solid waste sanitary landfill site and solid waste transfer station for the urban area of Yuanba District, various alternatives have been analyzed in terms of project location, leachate treatment and mode of solid waste transfer system.

DRA CONSULTING TEAM 11 APRIL 2010 Summary Environmental Impact Assessment for Yuanba Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP) Project Location

Two options have been proposed for the location of the solid waste landfill site of Yuanba District, as presented below:

Site 1 Site 2 Thick soil layer, easy to get Thick soil layer, easy to get Foundation of covering soil covering soil the Site

Conclusion Site 1 is located in the planned urban area of Yuanba District, which will affect the urban development, and there is no space for future development. Therefore, Site 2 is more suitable for the proposed landfill site. Leachate Treatment

Two options have been proposed for the leachate treatment for the proposed solid waste landfill site, as presented below:

TABLE 0-2: ALTERNATIVE ANALYSIS FOR LEACHATE TREATMENT OF YUANBA LANDFILL SITE

Advantages Disadvantages

Option 1: - Good and stable effluent - Complicated process; Ammonia quality, able to meet current - High investment and operation Stripping leachate discharge requirements cost; +MBR of “Pollution Control Standard for - Require more equipment. +Nanofiltration Domestic Solid Waste Landfill Site” (GB16889-2008);

Option 2: - Wide application in China, - Complicated process; Medium - mature technology and high - High energy consumption, high temperature treatment efficiency; equipment loss and thus high +MBR+Reverse - Good and stable effluent operation cost; Osmosis quality, able to meet current - High maintenance and leachate discharge requirements management requirements. of “Pollution Control Standard for Domestic Solid Waste Landfill Site” (GB16889-2008).

Based on the above analysis, Option 2: Medium -temperature +MBR+ Reverse Osmosis, is economically and technically more reasonable and feasible, and thus it is recommended as the treatment process for the leachate from the proposed landfill site. Type of Solid Waste Transfer Station

According to the process flow and the compacting degree of solid waste, the transfer stations could be classified as direct transfer and compacting transfer, whose characteristics are listed in the table below.

TABLE 0-3: COMPARISON OF DIFFERENT MODES OF SOLID WASTE TRANSFER SYSTEM Mode of Mode of Direct Compacting Transfer Transfer Pushing force on No High garbage

DRA CONSULTING TEAM 13 APRIL 2010 Summary Environmental Impact Assessment for Yuanba Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP) Mode of Mode of Direct Compacting Transfer Transfer Garbage Compactness in Low Higher Container Adaptability to properties of Good Good transferred garbage Airtightness during Relatively good Relatively good transportation Equipment Investment and Low High Operational Cost Efficiency of Low High Transfer Operation

The selected mode of transfer stations is closely related to the local economical development level. In view of the economic level of Yuanba District and the selected mode of transfer stations for other similar counties in Sichuan, the mode of direct transfer is recommended for Yuanba subproject, that is, the garbage is collected in the container in the transfer station and the full container is sent to the landfill site for disposal. The garbage will not be compacted in the container.

WTP

For the two proposed WTPs under this subproject, in view of their small treatment capacity, two kinds of treatment processes have been compared, as presented in the table below:

TABLE 0-4: COMPARISON OF TWO WATER TREATMENT PROCESSES Option 1: Option 2: Inclined-tube settling tank + Integrated Water Clarifier Pressure Filter - With good precipitation effects; - Low project cost; - No need for large valve; fully - Short construction period; automatic flushing; - Integrate the processes of Advantages - Easy operation; sedimentation and filtration; - No negative hydraulic head during - Little land occupation; filtration. - Stable treated water quality. - Relatively complicate tank structure; - Difficult for the loading and unloading of filter media; - Insufficient back-flushing with the flushing water tank on top of the filter; - Difficult for the general elevation layout of the treatment structures due - Anti-corrosion treatment is Disadvantages to higher effluent elevation and thus required for steel tank. higher elevation of the settling tank before the filtration; - Instable treatment effects, especially in view of the small capacity of proposed WTPs; - High difficulty for filter construction.

DRA CONSULTING TEAM 14 APRIL 2010 Summary Environmental Impact Assessment for Yuanba Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP) Based upon the above comparison, although additional anti-corrosion treatment is required, Option 2 still has several advantages over Option 1, such as short construction period, low project cost and little land occupation. Especially in view of the very limited land available in the project towns for WTP construction, the integrated water clarifier could significantly save the land use. In addition, the process has been widely applied to many small-scale WTP projects in recent years with stable treated water quality proved. Therefore, for the proposed Wangjia WTP and Hongyan WTP, the integrated water clarifier is recommended as the water treatment process.

WWTP Project Location

For the proposed Wangjia Town Wastewater Treatment Plant, two optional locations have been compared, as detailed below:

TABLE 0-5: COMPARISON OF PROPOSED LOCATIONS FOR WANGJIA TOWN WWTP

Option 1 Option 2

Location Shiban River, in No.1 Community of Zhushi Ditch, in No.1 Community of Hongmiao Village, Wangjia Town Hongmiao Village, Wangjia Town

Description Just neighboring the river bed on the Covering an area about 4mu; about downstream of Shiban River; only 70m away from the residential area; about 1mu; only about 20m away from the ground elevation of the site is about the residential area; and most of all the 25m lower than other areas; and all the wastewater from the town collects wastewater from the planned urban here. area collects here.

Conclusion Based on the following reasons, Option 2 is recommended as the location for the proposed Wangjia Town WWTP. 1) It is relatively far away from the planned residential areas, and the project completion will have no obvious environmental impacts; 2) There is enough space for long-term expansion; 3 The local traffic is convenient for construction implementation and management; 4) There is no resident and other sensitive receptor within 70m around the proposed site, and it will involve no resettlement. Wastewater Treatment Process

For the two proposed WWTPs under this subproject, three options of treatment processes have been compared, as presented in the table below:

In general, since the treatment capacity of the proposed WWTPs is very small with little content of heavy metals and good biodegradability, Option 1 (A2/O) is recommended as the treatment process to meet the required Class IB requirements of GB18918-2002. SLUDGE TREATMENT PROCESS

There are mainly two optional treatment processes for the sludge not requiring digestion, as presented in the table below.

TABLE 0-7: COMPARISON OF SLUDGE TREATMENT PROCESS

Option 1 Option 2 Item Gravitational concentration and Mechanical Treatment dewatering Sludge storage tank + Sludge concentrating tank + Main structures Concentrating & dewatering house Dewatering house + Sludge shed + sludge shed Sludge concentrating & Sludge scraper for concentrating Main dewatering machine + Chemical tank + Dewatering machine + equipments dosing equipment Chemical dosing machine Land Small Large occupation Total usage of 3.5 5.5kg/TgDS 3.5kg/TgDS flocculant No large-scale open structure for Open sludge concentrating tank Environmental sludge, with little environmental with unpleasant odor and great impact impact environmental impact Total cost of Low High civil works Total equipment Normal High cost Secondary pollution of No pollution With pollution phosphorus in residual sludge In terms of land occupation, environmental impact, total cost of civil Conclusions works and equipments, and secondary pollution of residual sludge,

Option 1 Option 2 Item Gravitational concentration and Mechanical Treatment dewatering Option 1 (mechanical treatment) is advantageous over Option 2 (Gravitational concentration and dewatering), therefore, Option 1 is recommended for this project.

As for the mechanical treatment process, three options have also been considered, as detailed below:

TABLE 0-8: COMPARISON OF SLUDGE MECHANICAL TREATMENT PROCESS

Option 2: Option 3: Option 1: Mechanical Centrifugal Belt thickener + Belt integrated equipment thickening + dewatering machine for sludge thickening Centrifugal and dewatering dewatering machine

Advantages - Reasonable - Compact and single Clean operational equipment price; equipment without any environment, low labor - Produced in China transitional process; intensity, low chemical with mature operation - Good environmental dose and allow experience. conditions with the continuous operation. least chemical consumption.

Disadvantages Additional sludge High equipment cost High equipment price, storage tank and large installed capacity supporting filling and big noise; facilities are required additional sludge after thickening, which storage tank and will make the system supporting filling more complicated with facilities are required more land occupation after thickening, which and poor operational will make the system environment more complicated with more land occupation and poor operational environment.

Since the treatment capacity of both proposed WWTPs is very small, the generated residual sludge is very limited, Option 2, Mechanical Integrated Equipment for sludge thickening and dewatering is recommended for sludge treatment of this subproject.

Geology

Yuanba District is situated in the transitional zone from the low mountains to hills at the northern edge of . The topography is high in the north and low in the south and inclines from east to west. Topographically, the district is dominated by Da’nan Mountain Network, the low-mountain network to the east of and to the south of Nanhe River, which accounts for 84% of the land surface area of

DRA CONSULTING TEAM 19 APRIL 2010 Summary Environmental Impact Assessment for Yuanba Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP) Yuanba District. The low-mountain network centers at Meilingguan in the north of the district and extents in the directions of east, west and south with the average elevation about 900m. In terms of geomorphology, the area consists of middle mountain, low mountain, river valley and terrace. The local earthquake intensity is VII degree.

The urban area of Yuanba is situated on the first alluvial terrace of Changtan River. The built-up urban area is developed in a belt-like zone along the river, which is surrounded by low mountains and hills with the natural geomorphic features of river valley between mountains.

The proposed landfill site is located in a valley surrounded by low mountains with low-lying valley bottom in the middle. Based on the engineering geological survey and borehole drilling findings, from the top down, the strata of the landfill site consist of:

(1) Quaternary Holocene Series gravelly soil (Q4pl): in brown yellow, loose, slightly wet, mainly consists of clay and a small amount of mudstone, sandstone gravels and detritus, occasionally mixed with plant roots and grass roots; the soil texture is very inhomogeneous; It is mainly distributed at the bottom of the valley with the thickness of 0.20 0.70m.

It mainly consists of clay-type minerals and detritus; arenaceous and muddy cementation; the surface is strongly weathered, with fragmentation along the joints; the cores are in fragments and short columns with low recovery factor, the RQD index is mostly less than 15%. The depth of strong weathering is normally between 1.0 1.5m. The cores of mudstone with medium weathering are mostly in long and short columns with the recovery factor more than 60% and the RQD index more than 55%; The rock mass is relatively complete with the basic quality of Grade IV, classified as soft rock.

Wangjia Town is located at the southern end of Da’nan Mountain in the low- mountain area, where the massifs are mostly beam-like or table-like with slow slope and spacious valley. The normal elevation is about 800m with the range between 532m and 1134m.

Hongyan Town also shows the landform of low mountain and deep valley, which is cut by Jialing River into several parallel ridges. However, most of the town is located in the valley along the river.

Climate

Yuanba District is located in the transitional zone between Sichuan Basin and Northwest Plateau. It is located in the subtropical humid monsoon climatic zone and dominated by the inland basin climate, which is also greatly affected by the continental climate of Northwest Plateau. The climate is mild and humid with plentiful rain. Late spring, long summer, cool autumn and cold winter could summarize the differentiated climatic features of four seasons in the area. The average annual temperature is 17 . It is cold and dry in winter and spring with the minimum temperature of -8.7 -10 ; and it is hot and humid in summer with the maximum temperature of 38.9 41 . The raining season is June~September, when the rainfall accounts for 75% of the annual rainfall. The average annual rainfall is 1058.4mm, and the maximum annual rainfall is 1587.2mm. The average annual sunshine duration is 1389.1 hours, and the frostless duration is 263 days by average. It is also a windy area, especially in winter and spring. The average annual evaporation is 1499mm. The dominant wind direction in winter and spring is

DRA CONSULTING TEAM 20 APRIL 2010 Summary Environmental Impact Assessment for Yuanba Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP) northwest with the maximum instaneous wind speed of 28.7m/s; in summer, the dominant wind direction is southeast.

Hydrology

Surface Water

The main rivers in Yuanba District (with the catchment area over 100km2) mainly include Jialing River, Bailong River, Donghe River, Xihe River, Qingjiang River and Nanhe River, which all belong to the Jialing River System.

Jialing River runs from north to south with the length of 169km within the district. Its average annual flow rate is 450m3/s, the peak flow rate is 16700m3/s, and the minimum flow rate is 11m3/s; Its water level varies between 469.89m and 472.44m, and the historical highest water level is 479.01m; Its average annual flow velocity is 2.05 3.95m/s; and it is open to the navigation of ships with the tonnage around 35t.

Changtan River is the main river in the urban area of Yuanba District with the function of flood discharge and irrigation.

Ziyun Reservoir and the upstream sections of Nanhe River and Yudong River are the planned water sources of Yuanba District with the total water supply capacity of 33000t/d for the long term.

Wangjiawan Creek is the proposed receptor for the leachate from the sanitary landfill site to be constructed under this subproject. Its main function is flood discharge. Its average flow rate is 1.4m3/s, and there is no drinking water source protection zone within 10km downstream of the treated leachate outfall on the creek.

Wangjia Town: There are totally 3 reservoirs in the town with the storage capacity of 760,000m3, which could cover the irrigation of 1450mu farmland; there are 303 mountainous ponds with the efficient storage capacity of 800,000m3 covering the irrigation of 1800mu farmland. Zhangjia River originates from the Motan Gongnong Reservoir and runs through the town from north to south. The river has the surface width of 50ü60m and the length about 13km within the town.

Hongyan Town: Jialing River runs through the town, and there are one small- scale Type 2 reservoir and 278 mountainous ponds in the town.

GROUNDWATER

In the terrace and ridges from Taigongsi to Xinchang, the groundwater is fissure shallow water in red bed detrital rock (weathering zone) and confined water in deep strata with good water yield property, and the runoff modulus more than 0.4l/s·km2. The fissure shallow water in the low-mountain areas to the south of Zhaohua and Ziyun has the medium water yield property with the runoff modulus between 0.2~0.4 l/s·km2; there is also fissure shallow water with relatively poor water yield property in the river valley area such as Yuanba Town, and its runoff modulus is less than 0.2 l/s·km2.

According to the hydro-geo survey carried out in Feb. 2010, the strata of the proposed Yuanba landfill site mainly consists of Quaternary Holocene Series gravelly soil classified as the permeable stratum and the Middle Jurassic Series Shaximiao Group mudstone (J2s) with poor water-bearing capability. The wellspring runoff is 0.01~0.05l/s, and the groundwater runoff modulus is less than 0.2l/sgkm2.

DRA CONSULTING TEAM 21 APRIL 2010 Summary Environmental Impact Assessment for Yuanba Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP) The permeability coefficient of the sandstone layer is normally between 0.356~0.467m/day.

Restricted by local topographic, hydrological and structural conditions, the groundwater of the site is mainly recharged by atmospheric precipitation, both the occurence space and migration passage of groundwater are sandstone interlayer. Part of the groundwater is discharged through gully, and part migrates along the stratum to the deep. The general flow direction is to the west.

Ecology

Forest covers a vast area of Yuanba District with the forest land area of 69565ha and the forest coverage rate over 49.4%. The living wood storage is in total 5.06million m3. As an important based of commodity grain for Guangyuan Municipality, the grain and oil-bearing crops of Yuanba Districts mainly include paddy, maize, rape and peanut. The local climate is suitable for mulberry plantation and sericiculture. The plantation of snow pear, grape, kiwi fruit, flue-cured tobacco and tung tree also begins to take shape.

According to the investigation, there are a lot of human activities in the project impacted areas, and there is no precious and rare animal and plants involved.

SOCIAL & ECONOMIC SETTINGS

Economic Development

With the total population of 238,000, the realized GDP of the whole Yuanba District in 2007 was 138,533yuan with the growth of 14.6% compared with the year before.

Historic Relics and Tourism Resource

As a key part of the “Shudao” (the vital communication line between two ancient kingdoms of and ) tour, Yuanba District has rich sightseeing resources such as the ancient town – Zhaohua, the No.1 Mountain of Guanyuan – Yuntai Mountain, Taigong Red Army Mountain, Baiguoxiang Mountain, Yunv Lake, Ziyun Lake, Pingle Temple and Jiangjun Mountain. However, according to the EIA investigation, the project involves no precious historic or cultural relics.

Impact Assessment & Mitigation Measures

ANTICIPATED BENEFITS FROM YUANBA SUBPROJECT

The four proposed components of the Yuanba subproject will significantly improve the environmental conditions and quality of life in the concerned urban area and towns through the following results: • Facilitation of post-earthquake reconstruction works with easier access to the involved project areas; • Improvement of local road network to meet future traffic needs necessary to achieve the social and economic development targets of both the urban and rural areas of Yuanba District; • Improvement of current water supply to meet the future water demand necessary and thus to support the social and economic development of the project towns; • Protection of local water resource by introducing wastewater treatment for the project towns; • Improvement of municipal wastewater and solid waste collection with evident benefits in terms of urban quality of life and public health; • Enhancement of river quality and landscape in urban areas with direct effects on the quality of life of nearby residents; • Safe disposal of solid municipal waste with leachate and landfill gas control and management reducing pollution load to surface and underground water and abatement of GHG released in the atmosphere; • Improvement of public health and life quality of local residents through the provision of water supply, wastewater treatment and solid waste collection & disposal services.

POLLUTION ABATEMENT: Pollution abatement will result from the construction of new wastewater treatment facilities (Wangjia and Hongyan) and from the increased wastewater collection capacity in Yuanba urban area and the two project towns (Wangjia and Hongyan).The effluent from Wangjia WWTP will be discharged into Shiban River and finally flow into Jialing River; and the effluent from Hongyan WWTP will be discharged into Jialing River. By adopting the Class IB national standard for WWTP effluent, the two proposed WWTPs are expected to result in an annual pollution abatement of about 54.31tons of CODCR, 29.42 tons of BOD5, 40.73tons of SS and 6.79 tons NH3-N, as detailed in the table below.

IMPACTS AND MITIGATION MEASURES RELATED TO PROJECT LOCATION

Land Acquisition & Resettlement

According to the RAP, the implementation of the proposed Yuanba subproject will lead to the permanent land acquisition of 193.4mu (including 26.4mu farmland, 91mu forestland and 76mu land for construction), the resettlement of 18 households (54 residents) and the house demolition of 1280m3, as detailed in Chapter 6.

Physical & Cultural Heritage

According to the investigation carried out by local authorities during the preparation of the individual EIA, no physical and cultural heritage resource is recorded or observed around the involved project sites. For any potentially buried and unknown cultural resource which may be discovered during construction, appropriate protective measures will be immediately taken, as specified in Section 5.4.2.2.

Ecological Resources

All the proposed projects are implemented either in the rural areas that has been planned and will be developed soon or in the built-up urban areas. The project implementation does not involve: • Forest clearing; • Destruction of area known for sheltering protected or threatened biodiversity; • Encroachment into a protected area as a nature reserve; or • Creation of facilitated access to sensitive areas with further risks of illegal or uncontrolled encroachment.

The project will have no significant detrimental impacts on valuable ecological resources1.

Stability and Hydro-geological Conditions of Yuanba Landfill Site

According to the “Geotechnical Engineering Survey Report for Yuanba Domestic Landfill Site of Guangyuan Municipality” developed by Sichuan Tianli Engineering Design Co., Ltd. (dated November 2009), the site is of structural eroded hilly landform with a thin Quaternary covering layer only 0.2 0.7m thick. There is no fracture structure, and the integrity of rock mass is good. Most of the bed rock is exposed. The site slope is gentle, and there is no adverse geological effect like collapse, landslide and mudflow. Based on the regional seismic data, the site is about 45km from the main fault zone of Longmen Mountain Structural Zone. That is, the proposed site is located in a geologically stable region with unitary landform and far from the seismic zone.

1 It is not necessary to apply World Bank Operational Policy 4.04, on Natural Habitats

DRA CONSULTING TEAM 25 APRIL 2010 Summary Environmental Impact Assessment for Yuanba Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP) The project site is located on a high terrace with no large surface water and major torrential flood to scour the side slope. Currently the natural side slope of the site is under relatively stable conditions. The stability conditions of the site are good enough for the project construction.

To better understand the hydro-geo conditions of the selected Yuanba Landfill Site, the “Hydro-geo Survey Report for the Site of Yuanba Domestic Solid Waste Landfill Site in Yuanba Municipality” has been completed in February 2010. The specific conclusions are summarized as follows: • The proposed landfill site is of structural eroded hilly landform with only a thin Quaternary cover only 0.2~0.7m thick. The integrity of rock mass is good, and there is no distribution of fracture structure. The proposed site is of bag shape with the catchment area about 0.113km2. Such topography is in favour of rainfall collection, which means that the flood-preventive drainage system should be carefully designed. • The hydro-geo conditions of the proposed site are simple, and local groundwater is expected to have little impact on project construction. The site strata are developed in monocline with slow inclination angle. It mainly consists of mudstone with relatively good water insulation capability. However, it could not satisfy the requirements of impervious material standard. There is thin~medium thick fine sandstone in-between with good permeability, which will become good passage for leachate from the landfill site. • With the existing dump site which has been operated for over 10 years, the local groundwater and surface water has already been polluted to a medium extent. The proposed landfill site has to include necessary pollution control facilities in its design by strictly following the “Technical Specification for Domestic Solid Waste Transfer Station” (CJJ47-2006), “Standard for Hygienic Assessment of Domestic Solid Waste Landfill Site” (CJJ/T107-2005) and “Pollution Control Standard for Domestic Landfilling” (GB16889). • The proposed site is 4500m from the bank of Changtan River and 4500m from Yuanba Town. It is over 1000m away from the area with relatively low population density on the leeward. Its horizontal distance from the centralized groundwater water supply source of Yuanba Town is 4500m, and its distance from the main national highway 212 is 400m. The proposed project will have adverse impacts on local water environment and ecological environment. However, the impacts could be mitigated with proper measures.

As a conclusion, the selected site could generally meet the requirements for site selection of a solid waste landfill site in terms of hydro-geo conditions. However, the report has also made the following suggestions to prevent and control any potential impacts: • The existing solid waste dump should be cleared to implement the seepage prevention works on the side slope and bottom of the site by adopting both the vertical and horizontal seepage prevention measure. • A complete leachate collection system should be laid on the bottom of the site. • A separate flood and rainwater drainage system should be installed in the site, the wastewater should be separated from rainwater, and the collected water from outside the site and from the non-landfilling area within the site could be drained directly. • The flood and rainwater drainage system should be designed on the northern ridge of the landfill site. The flood control criterion of flood control works should comply with the requirements of relevant national standard such as “Flood Control Standard” (GB50201) and “Design Specification of Urban Flood Control” (CJJ50).

DRA CONSULTING TEAM 26 APRIL 2010 Summary Environmental Impact Assessment for Yuanba Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP) • 2-3 groundwater monitoring stations (holes or wells) and one surface water monitoring station on the upstream of Zhiqingdian Reservoir and Changtan River should be installed to implement the long-term water quality monitoring. • There is an abandoned plastics processing factory neighbouring the site in the west, which might cause hidden safety issues and should be removed.

Specific Impacts

SPOIL DISPOSAL

Certain volumes of spoil are expected from the project construction activities, which may require off-site disposal. The overall earthwork balance for this subproject is detailed in the table below:

CULTURAL HERITAGE

For any buried and unknown cultural resources that may be discovered during construction activities, corresponding mitigation measures proposed to eliminate such potential impacts are similar for all the components. Adequate training should be provided to the staff/workers on the knowledge of heritage protection. Construction will be immediately suspended if any archaeological or other cultural properties are found (chance finds). The relevant cultural authority, as well as PMO, will be notified promptly, and only after a thorough investigation (by the relevant authorities) will construction be allowed to resume.

TRANSFER OF SOLID WASTE FROM EXISTING DUMP SITE (SOLID WASTE COMPONENT)

As mentioned before, the proposed landfill site for Yuanba District is to be constructed on an existing dump site whose operation was started since 1999. With over ten years’ operation, it is estimated that there has been about 100,000m3 of solid waste dumped on the site. The construction of the new landfill site will easily lead to the landslide and collapse of the existing solid waste dump which will in turn affect the project implementation. The following mitigation measures have been considered to minimize the possible impacts: • Barriers will be set up to stabilize the solid waste dump left within the construction site to reduce the impacts on normal construction;

DRA CONSULTING TEAM 31 APRIL 2010 Summary Environmental Impact Assessment for Yuanba Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP) • Disinfection and odour removal measures will be taken to minimize the impacts on air quality due to the large amounts of air pollutants generated during the transfer of existing solid waste; • The leachate from existing dump will be discharged into the leachate collection tank through temporary drains to effectively reduce its impacts on local surface water.

IMPACTS AND MITIGATION MEASURES RELATED TO OPERATION PERIOD

Solid Waste

Aside general benefits from solid waste collection and management, some detrimental impacts may be observed as noise and odor nuisance, development of pests or pollution of surface or underground water resources by leachate release. • Noise: Since there is no farmer living within 500m of the proposed landfill site, and the operational activities will only be implemented during the day, it is expected that the project will result in no obvious noise impact. • Odor nuisance: The EIA report have proposed the following measures to control the odor from the landfill site during operation: (a) Spray biological deodorizer during the unloading of solid waste, and regularly clean the operational site; (b) Install odor-removing system for the sorting operation; (c) the cover soil should be compacted during landfilling by strictly following the operational procedure; (d) implement the greening works to reduce the odor impacts (e) set up 500m of the buffer zone outside the site. For the transfer station, proper odor-removing system will be installed to remove the odor, and 50m of buffer zone will reserved around the compacting workshop. In this way, no major detrimental impact is expected on the surrounding environment. • Development of pests: Compaction of waste and regular covering with soil will limit the risk of uncontrolled development of pests such as mosquitoes, flies or rats. • Leachate treatment: The total leachate generation from both the landfill site and the transfer station is estimated as 41t/d. The leachate from the landfill site will be treated by the leachate treatment system (using the process of Medium - temperature + MBR+ Reverse Osmosis) within the site to meet relevant requirements of GB16889-2008 and GB5084-92 (Effluent quality: CODcr 100mg/L, BOD5 30mg/L and NH3-N 15mg/L) before being discharged into the Wangjiawan Creek through a 650m drain. The collected leachate and other wastewater from the proposed transfer station will be regularly transported to the landfill site for treatment by suction sewage truck. • Pollution of surface water: The receiving water body of treated leachate is Wangjiawan Creek. Wangjiawan Creek is a flood-discharging river with the average flow rate of 1.4m3/s, and there is no drinking water intake within 10km downstream. With normal operation of leachate treatment system, the water quality of the creek will still be able to meet the Class III water quality target of “Surface water environmental quality standard” (GB3838-2002). However, the EIA still suggests to strengthen the seepage prevention measures on the site bottom and the daily maintenance of leachate treatment system in order to avoid any pollution resulting from accidental wastewater discharge • Pollution of groundwater: By strictly implementing the seepage prevention works consisting of soil, geotextile, HDPE membrane, geotextile and soil on the bottom and around the landfill site, the project operation will have no obvious impact on groundwater quality. In order to reduce the leachate production, drainage system will be implemented around the landfill site to divert stormwater from entering landfill cells. Also, compacted waste will be regularly

DRA CONSULTING TEAM 32 APRIL 2010 Summary Environmental Impact Assessment for Yuanba Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP) covered in order to limit rainwater infiltration and leachate production. For the transfer station, the leachate collection tank will be cleared day by day, therefore, there will be no impact on groundwater quality. • Pollution of downstream wells: The farmers’ residential area for the No. 4 Community of Xingshu Village is located downstream of the proposed landfill site. The drinking water of the village mainly comes from local groundwater and the upstream pond to the west of the landfill site. As revealed in the hydro-geo survey implemented for the solid waste component, the leachate from the landfill site has the possibility to pollute the western pond and the deep groundwater in the west. In addition, when the impermeable membrane is broken, the leachate from project operation could also pollute the groundwater downstream. Therefore, the drinking water source for the No.4 Community of Xingshu Village is possible to be polluted by leachate during project operation. To avoid any pollution of drinking water source for the downstream villagers, Yuanba District Planning and Construction Bureau has promised to replace the current drinking water source by installing tap water network for local villagers and introducing the water from Qingshu WTP (as the emergency water supply source for Yuanba urban area). The project is currently under design, and the construction is expected to be started by the end of June 2010. • Groundwater Monitoring wells will be implemented around the landfill site to control the efficiency of the leachate treatment system regarding the protection of the underground water. Based on the understanding of groundwater distribution within the landfill site from the project hydro-geo survey report, four monitoring wells will be implemented: one baseline monitoring well, about 30- 50m upstream of the groundwater flow direction; two pollution diffusion wells, 30m on both sides vertical to the groundwater direction; one pollution monitoring well, 30m downstream of the groundwater flow direction. In addition, the EIA consultants also request to monitor the downstream well of No.4 Community in Xingshu Village. • Passive collection of landfill gas will be implemented in the landfill with the installation of flares to automatically ignite the landfill gas when the methane content is over 5%. Landfill gas monitoring wells will be drilled at the perimeter of the landfill to monitor the methane content to minimize the risk of explosion. • Improper management of solid waste collection and transfer system will also result in the pollution of surrounding environment. Accordingly, the following mitigation measures have been proposed: a) Along the currently identified transportation route, there are mainly enterprises and shops, only a few centralized residential areas are involved, mainly along Jingzhao Road and Qingmei Road. The stay of vehicles in these areas will be reduced to minimize the environmental impacts ; b) Enclosed container and compressive collection and transfer system will be used for solid waste collection and transportation to prevent any undesirable exposure, scattering and leakage; c) Strictly separate any hazardous solid waste from the domestic solid waste; d) Strengthen the daily management of the transfer station; e) Ensure that all the solid waste from the dustbin, solid waste tank and the transfer station is collected and sent to the landfill site; f) Carefully choose proper type of vehicles for solid waste transportation, and the vehicles should be carefully cleaned after unloading; g) Regular maintenance of the vehicles should be carried out to ensure the good airtightness of the vehicles.

Road

The environmental impacts of road component during operation are mainly limited to the noise impacts on nearby sensitive receptors as identified in Section 5.3.

Since the population of Wangjia Town and Hongyan Town is very small, the EIA consultants only carried out the traffic noise projection for the urban area of Yuanba District

DRA CONSULTING TEAM 33 APRIL 2010 Summary Environmental Impact Assessment for Yuanba Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP) (Oujiahe Community). The results show that the residential houses beyond 10m on both sides of the project roads will be impacted by the traffic noise. Therefore, the EIA consultants has made the following suggestions to minimize the noise impacts on local residents: a) The traffic control should be strengthened for the involved project roads; it should be required that no new residential house should be planned within 10m on both sides of the roads; the locations of new sensitive buildings such as schools and hospitals should be at least 40-50m away from the sides of the roads.

Water Supply

Impacts from the operation of water supply treatment plants and associated facilities (water intake, raw water pipe and distribution network) are rather limited in number and magnitude, and generally can be easily mitigated. Most frequent impacts and mitigation to consider include: • Treatment of additional wastewater resulting from WTP construction: The proposed Wangjia and Hongyan WTPs will mobilize additional water resources for water supply (respectively 900m3/day and 250 m3/day) which will consequently result in increased wastewater treatment capacities; It is confirmed that the existing and short-term planned wastewater treatment capacities in Wangjia and Hongyan with two new WWTPs (respectively 500 m3/day and 120m3/day) under the same subproject will be sufficient to accommodate the additional flow of wastewater resulting from the new water supply components. • Production wastewater from water treatment process includes the wastewater from settling tank (52.5m3/day for Wangjia and 35m3/day for Hongyan) and the wastewater from the backflushing of filter tank (15.6m3/day for Wangjia and 10.4m3/day for Hongyan). The wastewater will be treated with settling tank to meet Class III requirements of “Wastewater Integrated Drainage Standard” (GB8978-1996) before being discharged into the urban sewage network. • Domestic wastewater from staff (4 persons per plant) will be limited for both WTPs, that is, 0.32m3 per day per plant, and the effluent will be treated with septic tank before being discharged into urban sewage network. • Appropriate disposal of generated sludge is required for the WTPs. Since the production capacities of both proposed WTPs are small, the production of sludge will be limited (5.17t/year for Wangjia WTP and 3.45t/year for Hongyan WTP, with the water content of 75% after dewatering), which is planned to be delivered to the landfill site of Yuanba District which is proposed under the same subproject and is expected to be put into operation since January 2011. • Chlorine dioxide leakage at the treatment facility. Risk is controlled by appropriate storage, handling and emergency response procedures. • Noise during the operation may affect the nearby residents. To minimize the noise impacts, the following measures have been proposed: Low noise equipments should be selected; the air blower should be equipped with mufflers; The high noise equipments, such as blower, sludge dewatering machine and centrifuge should be set in isolation booths with sound absorbing walls and roofing; Separate the WTPs from surrounding buildings with greening belts; Keep the equipments in good conditions with regular maintenance. • Dam Safety:

The proposed water intake for Hongyan WTP is Xinhua Reservoir. Xinhua Reservoir is a Type Small (I)2 Reservoir with the dam height of 23m, which is classified as a large dam according to relevant classification criteria3, and

2 The reservoirs of Type Small (I) are defined as the reservoirs with the capacity between 1-10million m3. 3 The dam with the height over 15m is defined as a large dam.

DRA CONSULTING TEAM 34 APRIL 2010 Summary Environmental Impact Assessment for Yuanba Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP) therefore, the World Bank Operational Procedure of Dam Safety (OP 4.37) is triggered. Required information related to the dam has been collected and submitted to the World Bank for review.

The hydraulic characteristics of Xinhua Reservoir are detailed in the table below.

TABLE 0-5: CHARACTERISTICS OF XINHUA RESERVOIR Type of Reservoir Small (I) Ordinary water level (m) 1011 Benefited Population 2360 Design flood level (m) 1012.64 Catchment Area (km2) 1.33 Exceptional flood level (m) 1012.76 Dam Height (m) 23 Dead storage capacity 25 (10,000 m3) Material of Dam Homogeneous Beneficial reservoir capacity 95 earth dam (10,000 m3) Dead water level (m) 1000 Total reservoir capacity 135 (10,000 m3)

With the inspection carried out according to the “Management Regulations on Reservoir Dam Safety in the People’s Republic of China”, Xinhua Reservoir is identified as a Class III dam. With the damage of “5.12” earthquake, the anti- sliding stability coefficient of the dam has decreased, and the rupture of the culverts for water-proof facilities and the damage of the spillway get more serious. To make the dam reach the dam safety criterion above Class II and to guarantee the operational safety of Xinhua Reservoir, the strengthening of Xinhua reservoir is currently under implementation and is expected to be completed in June this year. In this way, the water supply safety of Hongyan WTP during its operation could be guaranteed.

Wastewater Treatment

Most typical impacts of WWTPs refer to the discharge of treated effluent into local water body, to the sludge production and disposal, to noise and odor nuisances generated by the facilities (aerators, blowers, pumps etc) or during sewer maintenance: • Impacts on the quality of local surface water: There is no major detrimental impact but only beneficial impacts on local surface water from the wastewater component of Yuanba Subproject as a significant reduction of pollutant load presently discharged into the Jialing River system will be observed, as presented in Section 5.1. • Odors from aeration, sedimentation and sludge condensation tanks may affect surrounding areas of the facilities. Minimum 50m distance buffer zone away from the sources of odor (such as sludge storage tank, coarse and fine screens and sludge) will be respected; vegetation barrier will be planted; the generated sludge will be cleared day by day; and good maintenance practice will be taken in the plant to provide effective minimization of impacts. • Noise from pumps may affect the nearby residents. According to the EIA, the project operation will have no obvious impact on surrounding environment with the strict noise reduction measures taken for noise-producing equipments such as aerator, pumps, motors and dewatering machine and the setting of buffer zone (50m). • Domestic wastewater from staff (10 persons for Wangjia and 6 persons for Hongyan) will be limited for both WWTPs, that is, 3.2m3 per day per plant, and the effluent will be treated with septic tank before being discharged into the WWTP for treatment. • Sludge production, handling and disposal The project plans to use the integral sludge dewatering machine for sludge treatment. The residual sludge

DRA CONSULTING TEAM 35 APRIL 2010 Summary Environmental Impact Assessment for Yuanba Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP) will be dewatered within 3 hours after its generation and further processed to the water content of 60% in compliance with the national standard for solid waste landfilling. The estimated sludge generated from Wangjia and Hongyan WWTPs are respectively 0.50m3/d and 0.14m3/d, which is proposed to be delivered to the Yuanba Solid Waste Landfill Site under the same subproject for final disposal. The landfill site is about 37km from Wangjia WWTP and about 70km from Hongyan WWTP. The vehicles with enclosed container will be used for sludge transportation to prevent sludge leakage along the transportation route and the consequent environmental impacts.

Resettlement Action Plan

PEOPLE AND NUMBER OF PEOPLE AFFECTED BY LAND ACQUISITION AND HOUSEHOLD DEMOLITION OF THIS PROJECT

This project involves Baihua Village in Hongyan Township; Hongmiao Village and Gengxin Village in Wangjia Township; Xinghua Village and Yuanba Village in Yuanba Township. All above villages are in Yuanba District. The lands of 168 households (539 people) are requisitioned permanently, and houses of 18 households (54 residents) are demolished. The 18 households are both affected by land acquisition and house demolition. The project requisitioned 193.4 mu of land externally. Among the requisitioned land, there is 26.4 mu of farmland, 91 mu of forestry land and 76 mu of construction land. The area of demolished houses is 1, 280 m2, and all of these houses are made of clay and wood. The land acquisition and household demolition of this project are legal.

The project construction does not need take over other land for temporary use, because it can scientifically take advantage of vacant land to construct and stack construction equipment and materials. Residential houses can be rented as offices and living areas, so there is no need to requisite land for temporary use specially.

Among the 193.4 mu of land requisitioned by this project, there is 26.4 mu of farmland. Among the five affected villages in Yuanba District, the farmland of two villages is requisitioned: 18.9 mu of farmland in Hongmiao Village, Wangjia Township; and 7.5 mu of farmland in Baihua Village, Hongyan Township. This land acquisition does not result in that some people have the farmland which is less than 0.3 mu.

COMPENSATION CRITERIA OF LAND ACQUISITION AND HOUSEHOLD DEMOLITION IN THIS PROJECT

In this project, the compensation for requisitioned land and resettlement subsidy are as follows: RMB 26,296 per mu in Hongyan Township and Yuanba Township; RMB 24, 472 per mu in Wangjia Township; the compensation for non-farmland is 50% of the compensation standard.

Crop Compensation: if crops on requisitioned land will be harvested in spring and early summer, the compensation is equal to the overall value of output, namely RMB 579.6 per mu in Wangjia Township and RMB 622.8 per mu in Hongyan Township; if crops on requisitioned land will be harvested in autumn and winter, the compensation is equal to the overall value of output, namely RMB 708.4 per mu in Wangjia Township and RMB 761.2 per mu in Hongyan Township.

In this project, all demolished houses are made of clay and wood, and the compensation is in accordance with the highest standard, namely RMB 380 per m2.

BUDGET OF MIGRATION EXPENDITURE IN THIS PROJECT

In this project, the expenditure on migrant resettlement is about RMB 3,046, 500 (taxation excluded). Among the expenditure, the basic compensation directly paid to the affected people is RMB 2,519,000, the expense on management, supervision and evaluation is RMB 275, 600, and the unpredictable expense is RMB 251,900.

DRA CONSULTING TEAM 37 APRIL 2010 Summary Environmental Impact Assessment for Yuanba Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP) RESETTLEMENT OF LAND REQUISITION

People whose agricultural income is affected are only 29.62% of the overall affected people. Besides, the amount of requisitioned land is small, and the average farmland of each person is above 0.3mu. As a result, the land requisition could not reduce the affected people’s standards of production and living. Therefore, the monetary resettlement is enough to meet the resettlement demand of the affected people.

RESETTLEMENT OF HOUSE DEMOLITION

In this project, the house demolition is mainly in Wangjia Township, Yuanba District, and two resettlement approaches are provided for households whose houses are demolished: concentrated resettlement by self-construction and sparse resettlement by self- construction. The concrete arrangement is as follows:

Concentrated Resettlement by Self-Construction: the government requisitions the new house sites which will freely allocate to the households whose houses are demolished, according to the GFF 2009 No.10 File, namely a house for a household and 30 m2 for each person. The concentrated resettlement by self-construction has to be arranged in uniformity, and it has to be planned and constructed according to the standards of the ecologically well-being village. The infrastructure is constructed by the government.

Sparse Resettlement by Self-Construction: if peasants choose to build houses by themselves, the government will provide the free land of 30m2 for each person. Peasants have to apply for the land by themselves, and the expropriation unit will handle the procedures.

All houses demolished are made of clay and wood (on the old street), and the compensation is in accordance with the highest standard, namely RMB 380 per m2. At present, it cost RMB 210 per square meter to make house of clay and wood. Thus, those households whose houses are demolished can take advantage of compensation to rebuild their houses, and there is some money left.

PUBLICATION, PUBLIC CONSULTATION AND MONITORING

It is planned to publicize and promote the migrant resettlement plan in February, 2010.

In October, 2009, the household investigation and forum were applied to 50 affected households in order to know the affect of the land acquisition and house demolition as well as their wills and suggestions on project construction and resettlement. The public participated in all processes of this project through information publication, consultation, household survey and so on.

This project will monitor the whole process of land acquisition and migrant resettlement in two ways, the internal supervision and independent external supervision of the migrant resettlement institution. The progress and supervision condition will be reported to the World Bank periodically until the migrant resettlement comes to its end.

Social Assessment

INTRODUCTION OF THE RESETTLEMENT AREA

There are totally 4affected people resettlement areas related to the sub project loan from the World Bank in Yuanba, there into, 2 in Yuanba downtown, 1 in Hongyan Township and 1 in Wangjia Township.

Oujiahe Resettlement Community lies in Yuanba Village of Yuanba Township, covering 18.93mu. 45 households are settled here, including 139 people, mainly are the affected people of May 12 Earthquake. The community is planned, designed and constructed by the government with the funds including post-quake reconstruction subsidies and that raised by the residents themselves. The infrastructures are built by the government too.

Limin Homestead Low-rental Resettlement Community covers 10mu. The government allocates the land to build 150 low-rental suits, covering 7,500 m2, so as to help those low- income households who cannot afford to build houses. The first phase including 48 suits has been finished.

Hongyan Township Resettlement Community includes 54 mu requisitioned collective land to settle down 254 affected people households. The community covers 120 mu and is built by the affected people themselves with the governmental grant in the same architectural style.

Wangjia Resettlement Community lies at the southern bank of Shiban River at Jizhen Township. It is arranged by the government and it accommodates 49 affected people households. All infrastructures such as roads, pipe network and green area are built by the government and are for free use.

Above-mentioned 4 resettlement areas accommodate 498 households including 1,637 people, hereinto, 157 households are urban households including 469 people, 273 are rural households, including 971 people, and the rest 68 households are relocated households including 197 people.

RESETTLEMENT HOUSE CONSTRUCTION AND ALLOCATION

Yuanba resettlement houses are mainly planed and constructed by the government as a whole.

The price of the resettlement houses in the three townships is checked and ratified on the basis of cost price and is publicized. For the affected people, the unit price to buy the resettlement houses is only RMB 1,050/ m2, while the average price of the same level houses is RMB 1,800 -2,000/ m2. In the meanwhile, the affected people also enjoy preferential tax policies.

Limin Homestead Low-rental Resettlement Community was built by the government in the same style with an average area of 50 m2, mainly for the low-income households after the earthquake, at a rental price of RMB 1/ m2/month for permanent residence. The government owns the houses.

RESETTLEMENT HOUSEHOLDS’ WILLINGNESS AND ABILITIES

In the initial project stage, Yuanba Bureau of Planning and Construction has carried out a survey on the willingness of 280 people among the 1,637 people of 498 households. The surveyed people all showed their willingness of moving into the resettlement community.

DRA CONSULTING TEAM 39 APRIL 2010 Summary Environmental Impact Assessment for Yuanba Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP) Based on the compensation standards on damaged houses in Yuanba, the affected people households can get compensation of RMB 27,000 to 32,000 thousand on average. Besides, the government provides credit loan preference, namely, RMB 30,000 thousand for each family. So the total price of the resettlement houses is between RMB 45,000 to 75,000 thousand. Due to the governmental subsidies and the far lower price that the market price, affected peoples can choose to buy the houses based on their own minds, so it can be concluded that they are affordable.

To those low-income households, 150 suits of low rental have been planed for the residence of the vulnerable group.

LAND ACQUISITION AND COMPENSATION STANDARD

The resettlement area involves 102.83 mu acquired land, including 27.4 mu farmland and 75.43 mu construction land. The compensation of the acquired land consists of three parts: land compensation. The acquired farmland is compensated on the basis of 10 times of the annual average output of 3 years ago. Resettlement subsidies, which are calculated on the following basis: as for the per capita farmland over 1 mu, each mu is compensated on the basis of 6 times of the annual average output of 3 years ago; as for the per capita farmland below 1 mu, every resettlement-involved person is compensated on the basis of 6 times of the annual average output of 3 years ago; (the annual average output of Yuanba Township and Hongyan Township 3 years ago were RMB 1,384/mu, and of Wangjia Township, it was RMB 1,288/mu). The land compensation and resettlement subsidies of requisitioned non-farmland are calculated on a half basis of the above. Crop compensation, which is fulfilled as follows: if it is winter crop to be harvested in the current season, all shall be compensated on the basis of its output: RMB 579.6/ mu in Wangjia Township and RMB 622.8/mu in Yuanba Township and Hongyan Township; if it is spring crops, all shall be compensated on the basis of its output: RMB 708.4/ mu in Wangjia Township and RMB 761.2/mu in Yuanba Township and Hongyan Township.

HOUSE DEMOLITION, RELOCATION AND SETTLEMENT

The resettlement area needs to accommodate 68 relocated households with a house demolition of 7,280 m2.

The relocated households are involved in the wholly planned resettlement community. The house area is based on per capital 35 m2 residence and 10 m2 façade. Besides, the relocated households can also buy houses on the basis of per capita 35 m2 and 10 m2 façade at the cost price of RMB 1,050/m2.

PUBLIC PARTICIPATION

In the early stage of choosing the resettlement area, Yuanba Bureau of Planning and Construction carried out survey about and indoor visits to the affected peoples. Colloquia were held with the affected peoples (Colloquia Minutes are in Table 6-2) to survey their willingness on moving into the resettlement area and whether they are satisfied about the location. In addition, it also introduced the supporting policies, subsidies policies and resettlement manners for the vulnerable groups, so that the affected peoples have participated in the preparation of the project.

This will ensure a satisfactory and legal project implementation.

Environmental Management Plan

The Environmental Management Plan (EMP) covers all phases of the Project from preparation to construction and to commissioning and operation. They aim to ensure control of the environmental impacts through implementation of monitoring and mitigation activities. The full EMP of the Project will be incorporated into the construction and operation management plans of the Project as appropriate and will form part of the bidding documentation.

During project preparation and implementation, organizations with different environmental management responsibilities, such as PPMO, EPBs, Design Institutes, contractors and construction supervision companies have been or will be involved in environmental management. PPMO, contractors and IAs will be required to appoint dedicated and qualified environmental specialists to oversee environmental management activities and ensure implementation of the EMP.

ORGANIZATION

During project preparation and implementation, these various organizations with different environmental management responsibilities have been or will be involved in the environmental management activities. PMOs, contractors and IAs, will each nominate dedicated and qualified environmental specialists to undertake environmental management activities and ensure effective implementation of the EMP.

The Provincial PMOs will ensure that the Project’s progress and impacts are monitored and reported in line with WB’s requirements. The effectiveness of mitigation measures and monitoring results will be evaluated through the feedback reporting system. Corrective actions in responding to monitoring results will be taken as necessary. Concerned EPBs and PMOs will play critical roles in this feedback and corrective mechanism.

For consistency and cost management during construction activities, it is recommended that concerned cities rely on a common CSC for the environmental supervision and monitoring. In such situation, consolidation of monitoring data and dissemination of common rules and practices regarding environmental management will be strongly facilitated, and their efficiency improved.

The EMP provides detailed procedures for information exchange, reporting, data management and non-compliance resolution.
