Introduction
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 Wenchuan County 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 Mianyang, Guangyuan, Bazhong, Nanchong 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, Chengdu and Deyang.
- 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.
DRA Consulting Team 1 January 2010 Summary Environmental Impact Assessment for Cangxi 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 Comission is responsible for the approval of Investment Application Report, and the Ministry of Finance is responsible for the signing of Loan Agreement, the supervison 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 summarised in the following chart.

Background and Description of Cangxi Subproject
PROJECT BACKGROUND
The Jialing River Bridge located in the urban area of Cangxi County is the only passage directly connecting the new urban area (to the south of Jialing River) and the old urban area (to the south of Jialing River) of Cangxi County. However, this bridge was seriously damaged in the Wenchuan Earthquake with some piers cracked, the expansion joints shedded and the surface of approach road damaged. According to the bridge inspection and evaluation implemented by the Structural Engineering Testing Centre of Southwest Jiaotong University, the current technical status of the bridge is classified as between Class III (relatively poor) and Class IV (poor). The passage of heavy vehicles over 10t is not allowed. The local traffic authority has take measures to limit the weight and height of the vehicles passing the bridge, which has consequently affected the traffic across Jialing River, the production and lives of local residents suffering from the earthquake and the post-earthquake reconstruction of the county.
This Jialing River Bridge is also critical for the construction of Tingzi Water Control Project, Lanyu Highway and Lanyu High-speed railway and is the only path on the Tourist Ring Route in North Sichuan. Even with repair and strengthening, the old bridge can no longer meet the needs of these key projects and local socio-economic development. In addition, it is noted the rapid development of Cangxi County in recent years has been limited by the geographic location of the county town. Therefore, Cangxi County plans to construct 17.1km2 of new urban area in Jiefangba to the south of Jialing River, which makes the construction of a new Jialing River Bridge as an urgent need.
At the same time, in order to alleviate the traffic pressure of Cangxi urban area before the operation of the new bridge, it is also proposed under this subproject to repair and reinforce the old Jialing River Bridge for the safe passage of small vehicles.
COMPLIANCE WITH LOCAL PLANING
The proposed new Jialing River Bridge under this subproject is just the originally No.2 Jialing River Bridge proposed in the development master plan of Cangxi County, and the repair & reinforcement of the old Jialing River Bridge and the construction of another new Jialing River Bridge are also listed in the local Wenchuan Earthquake Recovery Plan.
PROJECT COMPOSITION
The Batch 2 infrastructure subproject of Cangxi County mainly consists of two components: the reinforcement of the old Jialing River Bridge and the construction of the new No.2 Jialing River Bridge. Some of the project details are presented in the table below.

Jiangnan Main Road is planned to serve the resettlement area for the earthquake victims. Currently Jiangnan Main Road is under construction, and 70% of the works has been completed.
DRA CONSULTING TEAM 8 JANUARY 2010 Summary Environmental Impact Assessment for Cangxi Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP)
Alternative Analysis
During the project development, various alternatives have been proposed, screened and compared with technical, economic as well as environmental criteria, especially those related to the project location and bridge type. Additionally, in response to the WB requirements, there will be a special section analyzing potential impacts if without the subproject.
With and Without Cangxi Subproject
Compared to the "With" project scenario, "Without" the Cangxi sub-projects the result would be:
z Without the reinforcement of the old Jialing River Bridge, during the construction of the new No.2 Jialing River Bridge, the traffic across Jialing River in Cangxi County will be severly constrained. Since the bridge is in poor conditions due to the damage of the earthquake, if without the reinforcement, the traffic safety could not be assured for future use.
z Without the new construction of No.2 Jialing River Bridge, the local traffic conditions will fall short of the rapid economic development of Cangxi County, especially the development of the planned Jiangnan New Area in the coming years, even with the reinforcement of the existing Jiangling River Bridge.
Bridge Location
As the key connection between the areas to the south and north of Jialing River for Cangxi County, two bridge locations have been proposed in the project FSR, both of which start from the national highway No.212 and ends at the intersections of planned roads in the Jiangnan New Area (as shown in the figure below). The routes of both options are in straight line with relatively good linear conditions. The geological conditions on the river sides for the two options are both relatively good, and the bedrock is shallowly buried with partial exposure, which makes both options suitable to be used as the bridge location.

Envionrmental Baseline Situation
PHYSICAL SETTINGS
Geography
As shown in Figure 0-2, Cangxi County is located at the northern edge of Sichuan Basin at 31e37’N~32e10’N and 105e43’~106e28’E. The county borders Nanjiang County, Langzhong City, Jian’ge County and Wangcang County with a jurisdictional area of 2330.19km2. As situated in the transitional zone between Sichuan Basin and Tibetan Plateau, thecounty has been considered a confluence of nature, economy, culture and transport among the three neighbouring provinces of Sichuan, Shanxi and Gansu.
The county town of Cangxi, Lingjiang Town, was located beside Jialing River at the confluence of the national highway No. 212 and the provincial highways of Cangjian and Cangba. As the political, economic, cultural and traffic centre of Cangxi County, the built- up area of the town is 7.5km2 respectively to the north and south of Jialing River.
Geology
The terrain of Cangxi County is high in the northeast and low in the southwest. The highest point of Changxi County is at Jiulong Mount with the altitude of 1369.2m, and the lowest point is at the boundary section of Jialing River with the altitude of 352m. The whole landform mainly consists of low mountains, deep-seated mounds and river valley.
According to Notification on Seismic Intensity of Guangyuan Area by Guangyuan Municipal Construction Commission No.317 (1992), the seismic intensity of Cangxi County is lower than Grade VI, which means the fortification is not required for this area.
Climate
Cangxi County is situated in a subtropical humid monsoon climate zone with plentifuly rainfall, long frost-free period, moderate climate and distinctive four seasons. Annual average temperature in Cangxi County is 16.9 , the lowest temperature is -4.6 and the highest temperature is 39.3 . The annual frost-free period is 288 days with annual average precipitation of more than 1100mm.
Hydrology
The water system of Cangxi County belongs to Jialing River Basin, which consists of Jialing River, Donghe River, 12 main tributaries and over 180 creeks all over the county covering a catchment of 2,3134km2 (As shown in the water system map of Cangxi County in Appendix 3). The passing flow capacity is 22.89billion m3 in total. Among others, Jialing River is the largest tributary of Yangtze River with the total length of 1119km and the catchment of 0.16 million km2. The runoff of Jialing River is mainly supplemented by the precipitation, and then by groundwater and snow melt water, therefore, its runoff shows great variation both in a year and from year to year. According to relevant statistics from 1954 to 2004, the annual average flow rate of Jialing River is 603m3/s and its runoff is 19billion m3. The flood season of Jialing River is from May to October, during which period the water volume accounts for 79.8% of the whole year, especially between July and September.
DRA CONSULTING TEAM 13 JANUARY 2010 Summary Environmental Impact Assessment for Cangxi Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP)
Due to the impacts of specific tophography, the highest rainfall intensity of the river basin is observed in the rainstorm-affected regions of Longmen Mount and Daba Mount. Cangxi County is just located in Daba Mount Rainstorm-affected Region. The average annual precipitation is 2.65billion m3, the average annual runoff is 1.03billion m3 and the average annual runoff depth is 437mm.
The groundwater resource in Cangxi County is plentiful with a reservation capacity of 37~65million m3/a.
Ecology
According to Ecological Environmental Investigation carried out for the project area in March 2009, most of the project areas are currently farmland, as typical agricultural ecosystem. The vegetation canopy mainly consists of local crops such as wheat and maize. The uncultured land is covered with thorns and weeds. The forestland is all fast- growing forest plantations. The local animals are mainly livestocks, and there is no large wildlife in the area, but mainly some small-size mammals, amphibians and various kinds of insects.
There is no national and provincial nature conservation zones, wetland and shoal ecosystem, rare and endangered wildlife affected by the proposed project.
SOCIAL & ECONOMIC SETTINGS
Population
With 39 towns/townships under its jurisdiction, Cangxi County has a total population of 780,000, in which the urban population of the county town is only 78000. With great efforts by the local government to facilitate the development of the new area to the south of Jialing River (as “Jiangnan New Area” in this report), it is expected that this urban population will increase from the current 78000 to 100,000 by 2010 and 200,000 by 2020.
Agricultural and Industrial Production
The economy of Cangxi County mainly depends on agricultural production. The local crops mainly include paddy, wheat, mais, rape and peanut. Cangxi County is also one of national production bases for oil, snow pear, kiwi, pomelo and silkworm cocoon.
Transport
No. 212 National Highway passes through the Cangxi County from south to north. Other than existing Baocheng and Nanda Railways, Lanyu Railway is now under construction in the Cangxi County, which will form transport network all over the county.
Jiangnan New Area
Jiangnan Subarea refers to the newly planned urban area located on the southern and western bank of Jialing River consisting of four parts, i.e., Duliba, Yangjiaba, Miaoya and Huajiaba. Among others, Jiangnan New Area at Duliba has been planned as the subcentre of Cangxi urban area integrated with the functions of external traffic, storage and logistics, scientific research, and residence. The built-up area is planned as 10km2 with a future population of 150,000.
Since there is no land available for the resettlement of earthquake earthquake affected people in the northern urban area after the earthquake, Cangxi County government has
DRA CONSULTING TEAM 14 JANUARY 2010 Summary Environmental Impact Assessment for Cangxi Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP) planned the resettlement area for the earthquake affected people in the Jiangnan New Area. One of the planned resettlement areas for the urban earthquake victims is situated to the south of Jiangnan Main Road, which is no more than 300m away from the southern end of the proposed Jialing No.2 Bridge. In addition, there are also 313 households of rural earthquake victims who will reconstruct their houses within 7km of the reinforced Jialing Bridge. Therefore, the project construction is significant for the daily life of the resettled earthquake victims.
To facilitate the construction of the resettlement areas, the road connecting the resettlemtn area and the new bridge is currently under construction. The 8million yuan project cost is financed by the special earthquake construction fund allocated by the Central Government, and the road project is expected to be completed by end May, 2010.

Impact Assessment & Mitigation Measures
ANTICIPATED BENEFITS FROM CANGXI SUBPROJECT
The proposed Cangxi subproject (repair & reinforcement of the old Jialing River Bridge and construction of No.2 Jialing River Bridge) will significantly improve the development of the county with the following expected results:
z The project construction, especially the repair and reinforcement of the old Jialing River Bridge will satisfy the urgent traffic needs of local residents, especially the earthquake-affected victims, between the urban areas to the north and south of of Jiangling River
z The project construction will provide the local residents with a more convenient access to working places, hospitals and schools in the urban area;
z The project construction will satisfy the traffic needs for the development of Jiangnan New Area, shorten the traffic distance across Jialing River in Cangxi County, and connect the main urban area with key traffic passages, such as railway station and highway, the planned economic corridor of Natural Gas Utilization Zone and thus expand the development space of the county town;
z The project construction will promte the optimization of local land use planning, especially the land use of local school and hospital;
z As a future landmark of Cangxi County, the proposed No.2 Jialing River Bridge will complete the tourist ring route in North Sichuan.
IMPACTS AND MITIGATION MEASURES RELATED TO PROJECT LOCATION
Land Acquisition & Resettlement
The repair and enforcemenet of the old Jialing River Bridge will involve no land acquisition and resettlement. According to the latest RAP, the land acquisition for the subproject is 12654m2 with 10 affected households and 47 inhabitants for resettlement, and there is no basic farmland protection zone involved. The appropriate measures have been accordingly proposed in the RAP to minimize the negative impacts on the local residents. The details are presented in Chapter 6.
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
ACQUATIC IMPACTS
Based on the information provided by Cangxi County Water Conservancy Bureau, the main species of fish living in the river section are carp and crucian. In the section of Jialing River affected by the proposed project, there is no precious or rare acquatic organism, fish
DRA CONSULTING TEAM 16 JANUARY 2010 Summary Environmental Impact Assessment for Cangxi Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP)
spawning site, national or provincial conservation areas, or wetlands or aquatic or riparian ecosystem of special value. The project construction is expected to result in the increase of water turbidity; however, such impact will diminish with the project completion. Therefore, the project will have little impact on the local acquatic lives.
VEGETATION IMPACTS
As mentioned before, the repair and reinforcement of old Jialing River Bridge will involve no land occupation and thus no impact on ecological resources in general. As for the construction of No.2 Jialing River Bridge, the land occupation is totally 25000m2, mainly consisting of water surface, farmland (but not basic farmland), shoal, garden plot and forest plantation. The project implementation will not result in:
z Destruction of area known for sheltering protected or threatened biodiversity;
z Encroachment into a protected area as a nature reserve; or
z 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.
The vegetation destruction is mainly the damage by the crushing of foundation construction, construction machinery, transportation vehicles and the destruction by construction workers, which will directly decrease the surface vegetation coverage rate and indirectly destroy the habitats of small wild animals resulting in their death or movement. According to the projection, due to the project implementation, the biomass will only decrease by less than 10%, and there is no rare or endangered wildlife and plants within the project influenced areas. Therefore, the project implementation will have limited impacts on the regional ecological environmental quality. In addition, during construction, the topsoil with a depth between 0.3 and 0.4m is proposed to be stored in a proper way, which can be reused for restoration or greening along the proposed bridge. Thus, negative impacts on ecological resources are acceptable and limited once appropriate migitation measures are applied. Generally speaking, the local vegetation within the construction site will recover within 2~3 years after the project completion.
SENSITIVE RECEPTORS
According to the project EIA, the key sensitive receptors during the construction and operation of the proposed Cangxi Subproject are identified as follows:

IMPACTS AND MITIGATION MEASURES RELATED TO CONSTRUCTION PERIOD
General Impacts
Construction activities are expected to generate the following adverse impacts:
z Air borne dust due to excavation, demolition, construction vehicle movement and materials handling, particularly downwind from the construction sites.
z Noise from construction equipment and vehicular movement, potentially affecting nearby residents.
z Removal of trees. The construction of approach road proposed together with the bridge may impose the cutting of few trees, most of them being fast-growing forest plantations mainly consisting of poplar and willow.
z Damage to roads: Heavily laden trucks may impact on road conditions and cause road surface damage, especially during periods of rainfall and high ground moisture content.
z Infectious diseases. During the project construction period, floating population will work in construction sites throughout the city. The mobility of outside people might bring external epidemic diseases to local communities.
Based on the results of the impact assessments and the goals of minimizing adverse impacts in accordance with application standards, regulations and WB safeguard policies, the following mitigation measures have been identified to be taken during the construction phase:
z Construction sites, transportation routes and materials handling sites will be water sprayed on dry and windy days up to 2-3 times a day, especially if these sites are near sensitive receptors, such as residential areas and schools. Using central concrete mixing plants where possible, and transport with sealed vehicles.
z Construction activities will be scheduled carefully with consultation with nearby residents to minimize the impact of noise from construction machinery. Night- time (22:00 to 06:00) and noon-time (12:00 to 14:00) uses of certain noisy machines, such as pile-drivers and concrete vibrators, will be prohibited in the vicinity of residential areas. Temporary noise barrier should be set up at construction site. Personal protection equipments, PPE (e.g., noise protection earplugs), shall be supplied to workers for protection from the intensive noise.
DRA CONSULTING TEAM 18 JANUARY 2010 Summary Environmental Impact Assessment for Cangxi Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP)
z In conjunction with the relevant authority, traffic flow regulation plans will be prepared in advance of construction in the congested urban built up areas.
z Temporary land occupation will be planned well ahead to minimize the disturbance and the land will be reinstated to its original condition on completion of construction. Top soil will be removed and stock-piled for use during land restoration.
z Construction materials will be stored in appropriate places and covered or sprayed to minimize dust.
z Construction waste will be promptly removed from the sites and transported to an appropriate disposal area approved by the local authorities. Burning of construction waste will be prohibited.
z Materials will be covered during transportation to avoid spillage or leakage.
z During the raining season, limitation of load access will be imposed on the contractor to reduce damage to the roads. Also, the contractor will be required to rehabilitate, at the end of the construction, the section of the roads which have been damaged by the traffic resulting from the transport activities.
z Contractors will be required to take necessary safety measures at the construction sites to protect the public, including warning signs to alert the public of potential safety hazards at and around the construction sites. Workers should be examined regularly and the infected people should be given immediate medial attention or quarantined.
z All contractors and construction supervisors will be required to participate in mandatory environmental and health and safety training programs prior to the start of construction.
The above mitigation measures, where appropriate, will be included in the tender documents and subsequently in the construction contracts as binding contractual requirements.
Specific Impacts
PUBLIC TRAFFIC
During project implementation, especially construction period, negative impacts on daily life of residents living near the project sites are inevitable. Since the existing Jialing River Bridge is the only bridge across Jialing River in Cangxi County, during construction, the movement of construction vehicles will occupy the existing roads andl pose negative impacts on public traffic of local residents. Correspondingly, specific mitigation measures have been proposed during EA preparation, which include: the traffic of the bridge should not be fully closed for construction, and certain lanes should be reserved for public traffic; the construction management needs to be optimized to construction management needs to be enhanced during construction to avoid the rush hours and thus the traffic jam as much as possible; the traffic organization of the project area should be strengthened with the support of local traffic authority. All the above mitigation measures will be implemented by the construction contractors under the supervision of project owner and supervision companies in charge. Furthermore, the construction activities are temporary in the short run which will pose no negative impacts after construction completion. Hence, detrimental impacts during project implementation are limited and acceptable.
DRA CONSULTING TEAM 19 JANUARY 2010 Summary Environmental Impact Assessment for Cangxi Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP)
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.
SPOIL DISPOSAL
The repair of the existing Jialing River Bridge will only limited amount of waste asphalt and concrete material, which will be collected and sent for landfilling as construction waste.
As for the construction of the new Jialing River Bridge, while satisfying the road construction requirements, the excavation from the roadbed will be used as the earthwork required by road construction as far as possible in order to minimize the spoil and the earthwork needed to be borrowed. On principle, there will be no earthwork allocation across the river.
During the construction of the new Jialing River Bridge, the earthworks to be excavated for is proposed to be 1132 m3, earthworks to be refilled is proposed to be 2500 m3 and spoil to be generated is proposed to be 1132 m3. In addition, earthworks of 2500 m3 need to be borrowed from the nearby borrow area. The details of the earthwork balance are presented in the table below.
TABLE 0-2: EARTHWORKS BALANCE FOR THE CONSTRUCTION OF CANGXI SUBPROJECT Earthwork to be Earthwork to be Earthwork to be Spoil (m3) Project Section excavated (m3)à refilled (m3)à borrowed (m3)à Earthà Stone Earthà Stone Earthà Stone Earthà Stone

For spoil disposal, a spoil disposal site is proposed on the inner side of the south embankment as the original borrow pit for the project of National Highway 212. It is approximately 2.2 km away from the proposed construction site covering the surface of 0.13 hm2. The capacity of the disposal site is 3100m3, which is sufficient to receive the spoil generated by this subproject.
To avoid the impacts on local farmland, the borrow area is proposed in the main river channel about 2km upstream and downstream of the project site covering an area of 80000m2. The area is currently abandoned grassland with about 130,000m3 earthworks available (as shown in the picture below). The required borrow for the approach road will be taken from the backfills of the Jiannan Avenue project.

FIGURE 0-1: PICTURE OF PROPOSED SPOIL DUMP SITE AND BORROW AREA
Spoil Dump Site Borrow Area
Construction Plan
To minimize the soil erosion erosion resulting from prject construction, the implementation of all the roadbed, drainage works and bridge is proposed during the dry season. If the construction period has to extend to the raining season, all the construction materials should be well covered in advance; and the slope of the constructed roadbed sideslope should be covered to ensure the clean drains and thus to reduce the rainfall erosion on the roadbed side slope.
The construction method of the bridge as proposed in the feasibility study report is as follows: Block O of the continuous rigid-frame beam will be cast in situ with Bailey Frame, which is followed by cantilever injection method when the strength satisfies the design requirements; the cast-in-situ section of the side span will be constructed with the full space support; the foundation of the main piers will be implemented on the construction platform by mechanical drilling with wall protection by steel pipe; the platform will be built with steel box, and the pier body will be cast aftert the platform completion; and the main piers will be constructed by setting up the supports with hoisting technique.As mentioned before, the bridge construction will avoid the raining season to prevent the drilling waste from going downstream together with the river flow.
During construction, the existing road will be utilized as far as possible for the access of construction equipments, materials and construction workers. Only a few access roads will be constructed for the project implementation.
Construction Camp
No construction camp is planned for the repair of the existing Jialing River Bridge; and considering the limited scope of the project site, there will be only one construction camp proposed for the No.2 Jialing River Bridge project, which is located on the southern embankment of Jialing River to the north of the proposed bridge location. It is in a piece of flat land temporarily occupied for the project about 500m away from the main river course. Both the material site and the machine washing area are proposed to be close to the living area for the convenience of centralized management.
During contruction, there will be at most 200 workes per day working on the site. The domestic wastewater from the construction camp is estimated as 6m3/d, which is proposed to be treated by the septic tank in the camp (with the treatment capacity of 10m3/d); the wastewater from machine washing will be about 3m3/d, which will be firstly treated by the oil-separating sand filter and then sent into the septic tank for treatment together with the domestic wastewater. The septic tank will be regularly cleared by local farmers for fertilizer and there will be no discharge into the river. The solid waste generated from the camp is
DRA CONSULTING TEAM 21 JANUARY 2010 Summary Environmental Impact Assessment for Cangxi Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP)
estimated as 100kg/d, most of which is degradable and could be treated in the septic tank. The rest solid waste will be collected and treated by the local environmental sanitation department.
Soil Erosion
According to the “Water and Soil Conservation Plan for No.2 Jialing River Bridge Project”, the total soil erosion during the project implementation is estimated as 434.96t, including 67.81t of original surface soil erosion and 367.15t of newly increased soil erosion resulting from the project. Since the project area is classified as the medium eroded area and characterized by abundant rainfall without dramatical variation in a year. Without proper mitigation measures, the soil erosion of this area will be aggravated with the project implementation and result in adverse impacts on local flood discharge, farmland safety and ecological environment.
Therefore, the following mitigation measures have been proposed in the water and soil conservation plan for this project:
z Engineering measures: mainly on drain construction and ground preparation;
z Vegetation measures: Sow 13.76kg of bush seeds and 8.6kg of grass seeds, and plant 422 bushes.
2 z Temporary measures: Cover the side slope of the approach road with 925m of non-woven fabrics in raining season;
z Management measures: Strengthen the supervision and monitoring, control the construction duration of earthworks to minimize the exposure time of the loss soil.
With the implementation of all the above measures, the soil erosion of the project area could be effectively controlled.
Potential Impacts on Navigation of Jialing River
Jialing River is planned as a Grade III navigation channel. With the implementation of the safeguard measures during project construction in accordance with the regulations of maritime administration, the requirements for safety navigation could be satisfied:
z The project owner should be responsible for the navigation safety of the river section within the construction site;
z Before construction, the constructor should submit the navigation safety regulations for construction operation to the local maritime administration for approval within specified time limit and obtain the “Permit for Construction Operation above and beneath water”;
z Before construction, the constructor should apply to the local navigation and maritime administrations for the issuance of navigation warning and navigation announcement in accordance with relevant regulations. The constructor should develop the navigation safety temporary management method for the construction period, which should be approved by the navigation adminitation, and the safety management responsibility agreement for the water area affected by project construction should signed to clarify the responsibility;
z Regular contact should be established between the constructor and the local maritime administration during construction, and the emergency action plan should be developed;
DRA CONSULTING TEAM 22 JANUARY 2010 Summary Environmental Impact Assessment for Cangxi Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP)
z In accordance with the safety requirements of local maritime administration, the constructor should set up necessary safe operation zone or guard zone in the construction site equipped with relevant warning signs or guard ships;
z During construction, the channel should be well protected by the constructor by avoiding the random dumping of solid waste in the river bed and taking the responsibility to remove the obtructions remaining in the water area affected by the construction activities;
z During the construction, when it is necessary to install the aerial cables or the underwater facilities, the requirements on both navigation clearance and design sailing depth should be satisfied; otherwise, relevant notification should be issued through local navigation or maritime administrations in advance with the estabilishment of temporary navigation-prohibited signs;
z The design institute of the bridge should include the cost for traffic safety supervision and maintenance, mounting and maintenance of navigation aids and channel maintenance of the project area into the overall cost estimate of the project;
z Upon the construction completion, the constructor should timely submit the project completion report relevant to navigation safety to the local navigation and maritime administrations and apply for project inspection and acceptance before the bridge is put into use.
IMPACTS AND MITIGATION MEASURES RELATED TO OPERATION PERIOD
Air Pollution
Upon the reinforcement of the existing Jialing River Bridge and the construction of the new No.2 Jialing River Bridge, the local traffic conditions will be greatly improved. Large-sized vehicles will not be allowed to pass the old Jialing River Bridge, and the traffic load of the old bridge is expected to be released with the operation of the new No.2 Jialing River Bridge. The current mitigation measures against air pollution for the old bridge are considered sufficient to satisfy the requirements of environmental protection. Hence, no specific mitigation measures have been proposed for the operation of old Jialing River Bridge after repair and reinforcement.
During operation of the new No.2 Jialing River Bridge, the following mitigation measures against air pollution have been proposed:
z Plant more trees around the sensitive receptors around the approach road and the bridge, which will help absorption of dust and flue gas resulting from the increased traffic and improve air quality;
z The policies to eliminate the old vehicles with higher emission and the regulations to strengthen the regulations on the emission control of motors will be implemented by the local traffic administration. The vehicles with incompliant emission are not allowed to run on the road;
z The stricter traffic control by local traffic administrations will lessen the impacts of traffic congestion on air quality;
z With regular and proper road maintenance by concerned local department, less dust will be generated from roads.
DRA CONSULTING TEAM 23 JANUARY 2010 Summary Environmental Impact Assessment for Cangxi Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP)
Noise Pollution
Upon the reinforcement of the existing Jialing River Bridge and the construction of the new No.2 Jialing River Bridge, the local traffic conditions will be greatly improved. Large-sized vehicles will not be allowed to pass the old Jialing River Bridge, and the traffic load of the old bridge is expected to be released with the operation of the new No.2 Jialing River Bridge. Consequently, compared to current situation, traffic noise nuisance around the old bridge will be alleviated.
As for the new No.2 Jialing River Bridge, the noise impacts are limited to the identified sensitive receptors around the project site, and the following mitigation measures have been proposed to alleviate the noise pollution during project operation:
z Plant more trees around the sensitive receptors around the approach road and the bridge;
z The stricter traffic control by local traffic administrations will lessen the noise impacts of traffic congestion;
z Forbid the construction of new noise-sensitive receptors within 100m away from road axes.
Potential Impacts on the Navigation of Jialing River
According to the “Navigation Environment Safety Evaluation Report for Cangxi County No.2 Jialing River Bridge”, Jialing River is planned as a Grade III navigation channel for the fugure, the highest navigable water level at the bridge location is defined as 371.58m, and the navigation net height is over 15m, which could satisfy the requirements of navigation clearance. The bridge location is about 4km away from the upstream Jialing River Bridge, which is compliant with the requirements of “Inland River Navigation Standard”. It is concluded that the construction of No. 2 Jialing River Bridge will have little impacts on the navigation conditions of the river section around the bridge site without any change of the safe navigation environment in general. With the implementation of following safeguard measures during operation phase, the navigation safety could be guaranteed:
z In accordance with navigation requirements, install bridge opening marks, navigation aids and collision prevention facilities for the piers of navigation holes to
z To ensure the navigation safety around the bridge site, it is suggested that the constructor should commission the long-term maintenance of lead marks and the improvement of navigation safety supervision mechanism to the local navigation department in the form of agreement after the bridge completion;
z The navigation management will be strengthened by local navigation departments, and the communication between vessels and between the vessel and the bank should be enhanced to enable the timely avoidance between vessels during navigation and thus to ensure the navigation safety.
Flood Risk
The flood control standard of the proposed No.2 Jialing River Bridge is designed as 1:100 years, and the flood control standard of the corresponding river section is 1:20 years. As justified in the “Flood Discharge Justification Report for No.2 Jialing River Bridge”, the water level for 1:100 years flood at the bridge location is 379.22m, and the floor elevation of the proposed bridge is designed as 393.18~416.23m, which is 13.96~37.01m above the 1:100 years flood level. At both ends of the bridge, the floor elevation is at least 16.68m higher than the 1:20 years flood level. In addition, since the river section in the urban area
DRA CONSULTING TEAM 24 JANUARY 2010 Summary Environmental Impact Assessment for Cangxi Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP) of Cangxi County is relatively wide, the piers only accounts for a small percentage in the wetted area and the width of the river section. According to the calculation, with the bridge construction, there will be no obvious change of flow rate distribution and main streamline for the upstream and downstream of bridge, and there will be little impact on the flood discharge capacity of the river.
The crest elevation of the embankment at the bridge ends is 377.5m, and the top elevation for the piers of the new No.2 Jialing River Bridge is over 390m whth the clearance over 12.5m. The clearance at the embankment crest could satisfy the passing requirements of the flood emergency vehicles. The construction of the bridge will have no impact on the flood fighting of the river section.
DRA CONSULTING TEAM 25 JANUARY 2010 Summary Environmental Impact Assessment for Cangxi Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP)
Resettlement Action Plan
1.1 AFFECT SCALE AND REAL OBJECT VOLUME OF THE PROJECT
This project involves the permanent land acquisition of 19 mu which belongs to ten households (47 people) in Group 3, Duli Village, Lingjiang Township, Cangxi County, and it does not involve the household demolition and other affected attachment. The project construction occupies the state-owned river shoal for temporary use which has not been utilized, rather than the farmland. This temporary land is free.
COMPENSATION STANDARD OF LAND ACQUISITION AND THE COMPENSATION PAYMENT
In accordance with Letter Concerning that Guangyuan Municipal People’s Government Confirms the Average Annual Output Standard of the Farmland during Three Years before the Recruitment (GFH [2008] No.105), the average annual output is RMB 1,849 in Lingjiang Township, Cangxi County, Guangyuan. The land compensation and resettlement subsidy are in line with the highest state criteria. To be exact, the compensation is 30 times as much as the average annual output during three years before the land acquisitiont, namely RMB 55, 470 per mu.
In accordance with Compensation Standards of Attachments on Requisitioned Land and Measures of House Demolition and Resettlement in GuangYuan (GFF[2009]No.10) which is issued by Guangyuan Municipal People’s Government, the compensation for crops should comply with the following criteria: if crops on requisitioned land will be harvested in spring or early autumn, the compensation will be equal to the whole value of the output, namely RMB 832.05 per mu; if crops on the requisitioned land will be harvested in autumn or winter, the compensation will be also equal to the whole value of the output, namely RMB 1, 016.95 per mu. The compensation for crops in this project is absolutely in accordance with the highest criterion of the annual output, namely RMB 1, 016.95 per mu.
Based on the project approval and measure, on-site survey is carried out. The survey data are checked by Cangxi Countyl Bureau of Land and Resources, and then signed by Cangxi County Finance Bureau and Leaders in charge. After that, Cangxi County Finance Bureau allocates funds to Cangxi Prefectural Bureau of Land and Resources which pays compensation to affected people directly.
AFFECT OF LAND ACQUISITION
Among affected people, there is no vulnerable group. People affected belong to Han group, so no minority is affected.
Due to affect from land acquisition of other projects, each person in Duli Village has the land which is less than 0.3 mu. Additionally, all peasants in this village had transferred into urban residents in 2008. Therefore, their reliability on land decreases. All people in the village voluntarily purchase endowment insurance, medical insurance and unemployment insurance in accordance with Circular on Trial Methods of Social Insurance Concerning Urban Residents Transferred from Land-Requisitioned Peasants in Guangyuan (GFF(2007)No. 21) which is issued by Guangyuan Municipal People’s Government.
Among the ten households affected by this project, a household is requisitioned one mu of land which is the least, and a household is requisitioned three mu of land which is the most. Nearly all land is requisitioned.
DRA CONSULTING TEAM 26 JANUARY 2010 Summary Environmental Impact Assessment for Cangxi Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP)
A research on household registration is carried out with the help of community leader in Lingjiang Township. Findings are as follows: among the 47 people in the 10 affected families, there are totally 32 laborers (they are over 18 years old. Men are below 60 years old, and women 55 years old); among them, 30 go out for work, one person is a serviceman and one is a college student. They do not live on agriculture. On such a base, the land acquisition does not produce great negative impact on their production and living. Besides, the land compensation in this project is in line with the highest standard, and it guarantees peasants’ rights and benefits to the great extent. Meanwhile, the purchase of social insurance assures them of the long-term living quality and standard.
RESETTLEMENT OF LAND ACQUISITION
This project directly influences 10 households, including Yang Qingfu and Chen Xiuliang, Yang Qingzhong and Zhao Wenshu, Yang Qinghua and Li Tingzhen, Luo Bixiu, Yang Xiaoliang and Xie Jibi, Yang Kexian and Zhao Jucai, Yang Qingyao and Wu Defen, Yang Yunliang and Kou Zhiyin, Yang Juliang and Xie Yuanhua, as well as Yang Qingxiao and Du Weibi. The following three kinds of people do not purchase the social insurance: people below 18 years old for they are not qualified to buy social insurance according to the state regulation; those peasant workers whose employers have bought social insurance for them; and those adults who is unwilling to buy social insurance. The other affected people who are old enough to retire (man over 60 years old and women over 50 years old) bought endowment insurance on July 28, 2009. The purchase standards of social insurance are as follows: pay 50% of urban residents’ overall social insurance of RMB 49,140 at once, namely RMB 24,570; begin to receive pension whose base value is RMB 285 in the next month after the purchase; later, the pension will increase timelessly in line with a certain ratio, as the state policies changes. Those people who are not old enough to retire should continue pay the insurance until the retirement, and they should continuously pay the insurance for 15 years. In 2009, urban residents should pay social insurance of RMB 7,011, so landless peasants should pay social insurance of RMB 3,005 in 2009.
As for the requisitioned land in this project, a household is requisitioned one mu of land which is the least and a household is requisitioned 3 mu of land which is the most. The compensation is 55, 470 per mu. According to the analysis on ability to purchase social insurance which is carried out property owners and community leaders, all affected households, can afford the social insurance of family members who are in line with conditions.
RESETTLEMENT BUDGET
Resettlement expenditures on this project, including compensation for land acquisition and house demolition, are counted in the overall expenditure of the project construction. This part of expense is mainly paid by the finance of Cangxi County Government.
The expenditure on migrant resettlement of this project is likely to be RMB 1,290,500 (taxation excluded).Within the expenditure, RMB 1,073,200 is used for direct compensation for those affected people, RMB 110,000 for expense on management, supervision and estimation, and RMB 107, 300 for unpredictable expense.

Social Assessment
DAMAGE CAUSED BY EARTHQUAKE
The 5.12 Wenchuan Earthquakes impacted 39 townships, 778 villages, 4,766 villager groups and 246,000 households (778,000 people) in Cangxi County. It caused 14 people dead and 1, 045 people injured in the whole county. The direct economic loss amounted to RMB 10.485 billion.
RELATIVITY BETWEEN THE RESETTLEMENT AREA AND PROPOSED PROJECT
Since people affected by earthquake could not be relocated in Jiangbei urban area, Cangxi County Government has planned resettlement area in New Jiangnan District. The centralized resettlement area for urban residents affected by earthquake is located in the south side of Jiangnan Main Road, and it is less than 300m far away from the south side of the relocated Jialing River Bridge. Therefore, the proposed project is quite important for the travel demand of people affected by earthquake in the resettlement area.
Except for the resettlement area, other 313 households of villagers affected by earthquake rebuilt their houses on original site within 7 km away from the relocated Jialing River Bridge. Therefore, the project is also important for travel and living of these villagers.
BRIEF OF THE RESETTLEMENT AREA
Cangxi County has three centralized resettlement areas for people affected by earthquake, locating in Mafangchang, Wudang and Jiangnan, with 1,709 relocated households (5,981 people affected by earthquake) in total. The resettlement area in Jiangnan is directly related to this project. It is about 300m away from the south side of relocated Jialing River Bridge, covering an area of 7.65 mu. 101 households (299 people) will be relocated there. The centralized resettlement in Jiangnan for urban residents affected by earthquake is planned, designed and constructed in uniformity according to the framework of residential area, and the houses have good supporting facilities. Each house in the area is equipped with water supply, wastewater pipe, natural gas, cable, power supply and communication in uniformity. The green works are also being completed in the area. The average floor area of every person is lager than before, and the post-disaster living standard of people affected by earthquake is obviously improved.
Moreover, 313 households (1,225 people) rebuilt their house by themselves within 7 km away from the south side of the relocated Jialing River Bridge. Currently, in order to ensure the living of people affected by earthquake, Jiangnan Main Road, Jiangnan WTP, the pipeline network of water supply, wastewater, gas and power supply are under construction busily.
COMPOSITION AND CHARACTERISTIC OF RELOCATED PEOPLE
There are totally 414 relocated households (1,524 people) which are directly related to this project. Among them, 101 households (299people) are located in urban area, while 313 households (1,225 people) are located in rural area. There are no vulnerable household among urban residents affected by earthquake, while there are 2 vulnerable households among villagers affected by earthquake, which are considered as poverty stricken families.
Urban residents affected by earthquake in the county town will be relocated in the centralized resettlement area, with 101 households (299 people) in total, accounting for 25 % of the overall relocated households and 24% of relocated people. These residents have
DRA CONSULTING TEAM 29 JANUARY 2010 Summary Environmental Impact Assessment for Cangxi Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP)
steady income sources. There is at least one person in each family with work or pension, so their income source is relatively stable. The average disposable income of every people is RMB 9, 385 Yuan per year.
Villagers affected by earthquake rebuild their houses dispersedly according to their demands of production and living, with 313 households (1,225 people) in total, accounting for 75% of relocated households and 76 % of overall relocated people. Some villagers go out for work, and some of them make business together with farming. Their incomes are comparatively unstable, and the average disposable income of every person is 7, 049 Yuan per year.
Villagers affected by earthquake who rebuild their house are located in Lingjiang Tow of Cangxi County. Among them, 21 households are from Gaocheng Village, 65 households from Hujialiang Village, 59 households from Jiangnan Village, 38 households from Jindou Village, 25 households from Jinling Village, 30 households from Qunhui Village, 22 households from Shaoping Village, and 53 households from Zhenshui Village.
SURVEY ON WILLING AND RESETTLEMENT ABILITY OF RELOCATED FAMILIES
80 families out of 101 relocated families were selected at random for the sampling survey on resettlement willing. The survey result showed that all survey families would like to purchase the resettlement houses, because their original houses were destroyed by the earthquake, the relocated houses in the resettlement area are better than their original houses, and the houses are affordable.
Leading by Cangxi County Party Committee and People’s Government, concerning officers from Construction Bureau, Land Bureau and Lingjiang Town Government conducted research on the willing of people affected by earthquake and problems during reconstruction by means of meeting, questionnaire, and public publication. All people affected by earthquake expressed their positive feedback on self-reconstruction with the support from the government. Meanwhile, they thought that the in situ reconstruction is propitious to the recovery of production and living.
SUBSIDY POLICY OF RESETTLEMENT
The detail subsidy standards of reconstruction houses for urban residents affected by earthquake are classified as four categories and five levels. Subsidy for the lowest income family with one to three members is RMB 27,000 to 31, 000, or RMB 33, 000 to 35, 000 for the families with four to five members; subsidy for the lower income family with one to three members is RMB 24,000 to 28, 000, or RMB 30, 000 to 32, 000 for families with four to five members; subsidy for the average income family with one to three members is RMB 21,000 to 25, 000, or RMB 27, 000 to 29, 000 for the families with four to five members; subsidy for the high income family with one to three members is RMB 5,000 to 8, 000, or RMB 9, 000 to 10, 000 for the families with four to five members.
The detail subsidy standards of reconstruction houses for villagers affected by earthquake are classified as two categories and three level: for the families with one to three members, RMB 16,000 for the normal family and RMB 20,000 for the poor family; for the families with four to five members, RMB 19, 000 for the normal family and RMB 23, 000 for the poor family; for the families with six or more than six members, RMB 22, 000 for the normal family and RMB 26, 000 for the poor family.
RESETTLEMENT POLICY FOR VULNERABLE GROUPS
According to household survey carried out by officers of Lingjiang Town Government and relevant Village Party Committees, as well as the information from people, there is no vulnerable household among urban residents affected by earthquake, while there are two
DRA CONSULTING TEAM 30 JANUARY 2010 Summary Environmental Impact Assessment for Cangxi Subproject under Batch 2 of Wenchuan Earthquake Recovery Project (WERP)
vulnerable households among villagers affected by earthquake, which are considered poverty stricken families. The support for the two families from the government is to increases the subsidy from average RMB 20, 000 to RMB 26,000 which is the highest standard. Moreover, the village government will organize villagers to help them for reconstruction and ensure the completion of the reconstruction.
CONSTRUCTION AND DISTRIBUTION OF CENTRALIZED RESETTLEMENT HOUSES
According to the freewill principle, 101 households in total affected by earthquake are willing to be relocated in Jiangnan Centralized Resettlement Area. The 101 set houses in the area are absolutely planned and constructed according to the demand.
The resettlement houses will be constructed according to the economical housing policy, the floor area of each house is about 60 to 80 m2, and the unit price is only 938 per square meter. Meanwhile, the government will offer the preferential policies of taxation and fees. Representatives of relocated families will conduct random draw in order to select the houses, following the registration order during the meeting for resettlement method and place, house area and house type. The results will be publicized by the notice.
SUSTAINABILITY ASSESSMENT ON PRODUCTION AND LIVING OF RELOCATED PEOPLE AFFECTED BY EARTHQUAKE
All 101 relocated households affected by earthquake in the centralized resettlement area will keep their former jobs, business or other living sources. Therefore, there are no problems such as finding jobs and re-shaping the social system. The only problem is that the distance between the residential area and working area will be longer, but it can be solved by many methods, including opening corresponding bus routes and utilizing personal vehicles. Since villagers affected by earthquake rebuild their houses on original site, there is no influence on their future life.
Therefore, after resettlement, both production and living of the people affected by earthquake will achieve the sustainable development due to relatively slight economic loss, guarantee from former income sources, preferential policies and fund offered by central and local governments.
SCOPE AND APPROVAL PROCEDURE OF LAND REQUISITION
The scope of land requisition for the resettlement area: the resettlement area is located in Duli Village, Lingjiang Town. The centralized resettlement area for people affected by earthquake is located in the south side of Jiangnan Main Road, covering an area of 7.56 mu. The land was classified as construction land and allocated by the state government. Relevant resettlement and land requisition were well completed in 2007 without any remaining issues.
PUBLIC PARTICIPATION AND COMPLAINT
In order to push the resettlement of people affected by earthquake in the planning area of the county town, many joint meetings were hold by Reconstruction Office of Cangxi County Government, Construction Bureau, Land Bureau, Lingjiang Town Government and representatives of families whose houses were severely destroyed or collapsed, such as 4 large-sized consultation meeting and many times of small consultation and survey.

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 Sichuan Urban Construction PPMO, the local PIU and PMO, EPB, Design Institutes, contractors and construction supervision companies have been or will be involved in environmental management. PMOs, contractors and PIUs 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 PIUs, will each nominate dedicated and qualified environmental specialists to undertake environmental management activities and ensure effective implementation of the EMP.
The local PMO will ensure that the project progress and impacts are closely monitored and reported in line with the WB requirements. The effectiveness of mitigation measures and monitoring results will be evaluated through the feedback reporting system. Corrective actions in response 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.
A conceptual organization arrangement between the main contributors during the construction stage is shown in the figure below.
