2 ADB Chongqing Urban-rural Infrastructure Development Demonstration Project II - External Environmental Monitoring Report
This project is a demonstration project of ADB-financed Chongqing Urban-rural Infrastructure Development Projects, aiming to achieve social harmony and balanced economic growth through coordinating urban and rural development. Due to the social and economic development differences caused by the unbalanced development in urban and rural areas, this project will selectively enhance the development potentials of the small and medium-sized towns and counties: (1) urban water supply system; (2) the flood risk management of various scales of rivers; (3) improving the urban and rural road links.
The total estimate cost of the proposed project is $307.43 million, among which $150 million is funded from the ADB loan. The project includes three investment parts: (1) Investment in the flood management; (2) investment in the water supply; (3) investment in the road network improvement. There are six subprojects in these three investment areas, including two flood management subprojects, three road network improvement subprojects and one water supply subproject, which are:(i) Rongchang Rongfeng River Water Supply Subproject (constructions of a 6.7-kilometer-long levee, a bridge and 8.5 kilometers sewage conduits, greening facilities and rainfall and flood level monitoring facilities);
(ii)Wulong Wujiang River Flood Management Subproject (constructions of a 2.6-kilometer-long levee and flood level monitoring facilities); (iii) Chengkou County
Urban-rural Road Network Improvement Subproject (reconstructions of 10.2 kilometers roads and the relevant infrastructures, including 2 bridges, 1.5 kilometers tunnels, 20.4 kilometers drainage ditches and greening facilities); (iv) Fuling District Urban-rural Road
Network Improvement Subproject (reconstructions of 16.2 kilometers roads and the relevant infrastructures, including 14 bridges and 32.4kilometers drainage ditches and greening facilities); (v) Shizhu County Urban-rural Road Network Improvement Subproject reconstructions of 25.3 kilometers roads and the relevant infrastructures, including 8 bridges and 50.6 kilometers drainage ditches and greening facilities); (vi) Wanzhou District Yangliu Water Supply Subproject (This subproject includes two phases, of which the total designed water supply capacity is 35,000m3/d. In the 1st phase, a water treatment plant with 20,000m3/d water supply capacity will be built, Including water treatment facilities, water quality monitoring facilities, power supply and distribution system, offices and other plant supporting facilities).
At present, all subprojects have been commenced and constructed (in which, the

3.4 Implementation Situations of the Mitigation Measures
During construction, potential impacts include soil erosion, noise and vibration, fugitive dust, solid wastes, and community and occupational health and safety risks. The main anticipated environmental impacts and risks include indirect and induced impacts of roads (soil erosion, earthwork, and downstream effects of flood control measures). Occupational and community health and safety from construction activities and operation, sustainability of exploitation of water resources for water supply, and potential risks to physical cultural resources and legally protected sites (nature reserves) will also need to be addressed. Overall, construction-related impacts are localized, short term, and can be effectively mitigated through the application of good construction and housekeeping practices and implementation of construction phase community and occupational health and safety plans. To ensure that construction contractors are able to implement the mitigation measures, the implementation unit (IU) makes the following arrangement:(i) environmental specifications will be included in the bidding documents to contractors; (ii) Identify responsibilities and use environmental standards as indicators of assessment; (iii) In the contract, the waste site, material transportation line, pit location and waste disposal are clearly defined (iv) Define the environmental management plan and monitoring plan in the contract. The project construction unit has established an environmental, safety and health emergency plan, and has filed and approved the project in the project management office. In the process of the construction, the environmental management team of the implementation unit enhanced on-site supervision, management and evaluation, and dealt with the problems found. Increased training for environmental protection and developed follow-up training programs. The reasonable environmental management measures adopted by the contractor reduce the impact of the construction on the environment. 1. Road subprojects The following potential impact and mitigation measures represents the prevailing construction impact of all road subprojects. Earthwork, soil stable, dust and noise controlling, machinery operation, building material transportation and national labor requirement impact management in the process of road construction. Most of the projects will purchase premixed asphalt to pave the road, which will cause remit smoke when heat and mixed. The density of smoke remitted from Chinese modern asphalt mix machine is 22.7mg/m3, which meet the emission standard of asphalt (80-150 mg/m3) of air pollutants (GB16297-1996) and ambient air quality standard (GB3095-2012) with the benzopyrene emission density is 0.01µg/m. EMP has additional restriction for the use of the machine. In addition, the asphalt mixture station shall be built beyond 500m from
22 ADB Chongqing Urban-rural Infrastructure Development Demonstration Project II - External Environmental Monitoring Report the residential area. 2. Spoil disposal: Road subprojects will make maximum use of spoil from construction earthworks through balancing cut and fill, the construction of berms for noise and wind protection of plants and facilities and earthworks for landscaping. The area’s most vulnerable to erosion include borrow pits, spoil sites, temporary construction sites, and other areas where surface soil will be disturbed. The most effective erosion control will be interception drainage to protect disturbed surfaces from surface flows. Construction plans will include erosion control prescriptions for construction work areas, including (i) constructing intercepting ditches and drains to prevent runoff entering construction sites, and diverting runoff from sites to existing drainage; (ii) limiting construction and material handling during periods of rains and high winds; and (iii) stabilizing all cut slopes, embankments, and other erosion-prone working areas while works are going on. All earthwork disturbance areas shall be stabilized within 30 days after earthworks have ceased at the sites.
3. Construction wastewater: Construction wastewater is produced from the maintenance and cleaning of mechanical equipment and vehicles, maintenance water for mixing and curing concrete, cooling water, and lost water and soil during the construction period which is discharged as pollutants. The effluent, comprised mainly of inorganic wastewater, commonly contains no poisonous and harmful substance, except suspended solid, but, if discharged in an improper manner, still has the potential to impact existing water bodies. Some oil-containing wastewater can arise from machinery repairs. Construction wastewater will not be discharged unto the surrounding soil or into surface water systems. Sedimentation tanks will be built, and after settling out of solids the upper clear liquid will be recycled for spraying the construction site (dust control), and the waste residue in the tank will be cleared and transported to designated landfills. Oil-containing wastewater will require the installation of oil-water separators before the sedimentation tank. 4. Gaseous air pollution: Construction machinery on all sites will consume petrol and diesel, releasing gaseous SO2, CO, and NOx. Equipment will be maintained to a high standard to ensure efficient running and fuel-burning. High-horsepower equipment will be provided with tail gas purifiers. Atmospheric monitoring will be carried out during the construction period. All vehicle emissions will be in compliance with relevant PRC emission standards.
5. Dust: Road construction sites will potentially produce fugitive dust from material storage areas, dump sites, concrete mixing, excavation and general site usage especially under windy
conditions. Material stockpiles and concrete mixing equipment will be equipped with dust shrouds.
23 ADB Chongqing Urban-rural Infrastructure Development Demonstration Project II - External Environmental Monitoring Report
The operators will regularly maintain the shrouds to ensure their effective operation. For both construction sites and construction roads, water spraying for the suppression of dust and maintenance of driving surfaces will be standard site management practice. Vehicles carrying soil, sand, or other fine materials to and from the construction sites will be covered.
6. Noise: Noise can be expected during construction due to construction machinery operation and transport activities. Construction activities will involve bulldozers, graders, excavators, concrete-mixing plants, rollers, and other heavy machinery. Noise intensity from these large machines operating is typically in the range of 80–98 decibels at the site (5m from operating
machinery). The transport of material, aggregate, concrete and waste material to and from sites will also cause noise impacts along the haulage routes. Activities with intensive noise levels will not only have an impact on the residents, but may also cause injury to construction workers operating the equipment.
7. Cultural relics: additionally, construction activities have the potential to disturb unknown underground cultural relics. Special attention should be paid and strict procedures should be established so that underground cultural sites can be identified and protected if they are discovered
during construction. The mitigation measures will include immediate suspension of construction activities if any archaeological or other cultural relics are encountered. The municipal cultural relic protection authorities, as well as the LPMOs, will be promptly notified, and construction will resume only after thorough investigation and with the permission of the appropriate authority.

It can be seen in Table 4 that the environment impacts mitigation measures in the construction sites of the Rongchang Rongfeng River Flood Management Subproject, Wulong Wujiang Flood Management Subproject, Wanzhou Yangliu Water Supply Subproject, Shizhu urban and rural road network improvement Subproject, Chengkou urban and rural road network improvement Subproject are implemented effectively in environment impact mitigation measurement and the environment management in the construction site are in order.
The results of the site investigation and monitoring of the environment supervisors are the downstream receiving water quality of the Rongchang Rongfeng River Flood Management Subproject, Wulong Wujiang Flood Management Subproject and Wanzhou District Yangliu Water Supply Subproject, Fuling district urban and rural road network improvement subproject and Shizhu county urban and rural road network improvement subproject, Chengkou urban and rural road network improvement subproject conform to the category III water quality standards; the above subprojects have taken corresponding measures to minimize the noise generated during the construction and there is no complaint so far. The noise generated has very little impact on the environment sensitive sites in the neighborhood and has not disturbed the residents; the waste earth and rocks excavated in the above subprojects have been backfilled nearby or reused so that the waste earth and rocks and pits are thoroughly used, meanwhile it has prevented the environment impacts and ecological damages caused by choosing another earth disposal site and reduced the load of the existing waste disposal areas in town or the district.
Up to the report period, Rongchang Rongfeng river flood management sub-project dredge detection report has been submitted by the third party testing unit. In Wulong subproject, anchor cable anti-sliding wall construction was the newly added variation work and conducted between March and May 2018. It was found that the over grouting mortar by anchor construction discharged directly to river bank or Wu River. The contractors have rectified timely and set up small sediment pools to process the slurry and the solid waste was moved to waste dump. In this EMT survey, the construction of anchor cable anti-sliding walls is in suspension because the new prices of BOQ have not been agreed by IA and ADB. No illegal discharging was found on site. In general, all of above projects conform with the requirements of local regulations,
comprehensive prevention and treatment, practical and beautiful in Developing and
Construction Project Water and Soil Conservation Technical Regulation (GB50433-2008).

Therefore, this domestic wastewater monitoring is not included in the monitoring plan. It can be seen that DO, BOD5 and TP in the surface water in the upper reaches of Rongfeng River exceed the standard, while DO, NH3-N, CODCr, BOD5 and TP in the surface water under the railway bridge in the lower reaches exceed the standard. According to the observation of the EMT and the inquiry of the Rongchang IA, the enterprises in the upper reaches of Rongfeng River and in the upper and lower reaches of the monitored area have stolen discharge behavior, which causes the monitoring index to exceed the standard. C01, C02, C03 have been completed, C04 is planting without any discharge, and the new C05 after the mid-term adjustment started on 28 November 2018, is currently doing the field clearance. There are no construction and domestic wastewater discharges. Therefore, the monitoring index exceeding the standard has nothing to do with the ADB project.

After visits and visual inspection on construction site, investigation on contractor or supervisory company’s daily record book and monitoring of all parameters of corresponding monitoring point locations at construction sites (table 9-28), the report finds out (1) The Wulong Wujiang Flood Management Subproject, the Yangliu Water Supply Subproject in Wanzhou District, the Fuling Urban-Rural Road Network Improvement
Subproject, the Shizhu County Urban-Rural Road Network Improvement Subproject and
the Chengkou County Urban-Rural Road Network Improvement Subproject all meet the
environmental standards of the relevant functional areas.
(2) The surface water monitoring indexes of Rongfeng River flood management sub-project in Rongchang exceed the standard, but because C01, C02, C03 have been
completed, C04 completed 90% of green planting, and there is no discharge at site. The new C05 is conducting field clearance, and there is no construction and domestic sewage
discharge. Therefore, the index exceeding the standard is not caused by the ADB project.
According to the inquiry from EMT to the IA, some enterprises in the upper reaches of Rongfeng River and the surface water sampling area are currently engaged in sewage
evacuation, which results in some surface water indicators exceeding the standard.
(3) After visual inspection on construction on site of subproject under construction, solid
wastes such as work shed’s wastes and construction wastes are all collected and disposed (regularly transport to local sewage disposal site). Thus it can be seen that implementation measures which are formulated by all subprojects EMP to alleviate pollution are well-done. All subprojects’ constructions have little impact on environment.

According to table 31, three methods listed above are mainly applied to carry out public consultation in all projects. It turns out that the public support the implementation of projects and they expect that the projects can be completed as soon as possible to benefit more areas and people.
3.7 Grievance Redress Mechanism
A grievance redress mechanism (GRM) was established in each project city/county incompliance with ADB´s SPS (2009) requirement to prevent and address community concerns and assist the project to maximize environmental and social benefits. In addition to serving as a platform to resolve grievances, the GRM has been designed to help achieve the following objectives: (i) open channels for effective communication, including the identification of new environmental issues of concern arising from the project; (ii) prevent and mitigate any adverse environmental impacts on communities caused by project implementation and operations; (iii) improve mutual trust and respect and promote productive relationships with local communities; and (iv) build community acceptance of the project.
The GRM is accessible to diverse members of the community, including more vulnerable groups such as women and youth. Multiple of entry, including face-to-face meetings, written complaints, telephone conversations, or e-mail, will be available. Opportunities for confidentiality and privacy for complainants will be honored where this is seen as important.
71 ADB Chongqing Urban-rural Infrastructure Development Demonstration Project II - External Environmental Monitoring Report
There are something related to GRM procedure and time frame in the following Matrix.

72 ADB Chongqing Urban-rural Infrastructure Development Demonstration Project II - External Environmental Monitoring Report
Stage 1: If a concern arises during construction, the affected person or group will submit a written or oral complaint to the contractor (or the contractor‘s environment health and safety officer or any on site construction personnel). Whenever possible, the contractor will resolve the issue directly with the affected person. The contractor will give a clear reply within one week. If successful, the contractor will inform the concerned IU, LPMO and the PPCC accordingly.
(i) Stage 2: If no appropriate solution can be found, the contractor has the obligation to forward the complaint to the PPCU within five (5) working days. The complainant may also decide to submit a written or oral complaint to the PPCU, either directly or via one of the GRM entry points (IU,
LPMO, local EPB). For an oral complaint, proper written records must be made. The PPCU will assess the eligibility of the complaint, identify the solution and provide a clear reply for the complaint within five (5) working days. The environment consultants of the loan implementation consultancy service will assist the PPCU in replying to the affected person, if requested to do so. The PPCU will also inform the ADB project team and submit all relevant documents. Meanwhile, the PPCU will timely convey the complaint/grievance and suggested solution to the contractors or operators of facilities as well as the complainant. The contractors during construction and the operators during operation will implement the agreed upon redress solution and report the outcome to the PPCU within seven (7) working days.
(ii) Stage 3: In case no solution can be identified by the PPCU, or the complainant is not satisfied with the proposed solution, the PPCU will organize, within two weeks, a multi-stakeholder hearing (meeting) involving all relevant stakeholders (including the complainant, contractor, facility operator, local EPBs, CPMO, IU). The hearing shall identify a solution acceptable to all, and formulate an action plan. The contractors during construction and the operator during operation will implement the agreed-upon redress solution and report the outcome to the PPCU. The PPCU shall accept complaints free of charge. Any cost incurred should be covered by the contingency of the project. The grievance procedures will remain valid throughout the duration of project construction and until project closure. The started subprojects have within the agreed upon time frame established multilevel appeal and complaint mechanism (contractor –owner unit -LEPB-CPMO) and set up complaints hot lines. The specific information is in Table 32.

The cutting earth has been utilized for filling work nearby. There is no impact on the environment. During the foundation excavation of In the upstream of the construction, reinstalled BK3+100-BK3+800 section retaining wall the water pipe to the other side of the river to August construction, because the foundation is in the avoid the construction area. The water pipe 2018 Maxi River, the excavation process affects repair work was completed in early December the drinking water source of some residents 2018. in Yuelai Town.
3.8 Focused Issues in the Current Period
3.8.1 Construction Environmental Protection Implementation in Fuling Damu Nature
Reserve Area
On January 19, 2019, the EMT (Wang Hong, Yan Guangcong and Yin Jian ), together with
Pang Kaiwen, the representative of the project construction unit, carried out a special
environmental protection inspection on the construction site of Fuling Damu rural road
sub-project. During the inspection, the construction unit introduced the implementation of the
project and the existing problems. The EMT inspected the construction starting point of the road,
the construction section of H-steel reinforced Pile-retaining wall, the section of Jiayu Mining
78 ADB Chongqing Urban-rural Infrastructure Development Demonstration Project II - External Environmental Monitoring Report
Road, the section of retaining wall along Maxi River, the end of the road and the temporary dump along the road, the environment expert gave on-site guidance to the environmental protection work of the construction unit, and put forward suggestions and rectifications for the existing problems. I. Site Inspection
At present, the construction progress of JuanDa road is lagging behind the original schedule. Approaching Spring Festival, most of the construction sites have been stopped. 1. Road Starting Point JuanDa road start point is located about 60 meters above the opposite bank of Maxi River, and only a few earthwork and retaining walls have been conducted. Field observation shows that the forest outside the roadbed of near maxi River is seriously damaged due to waste spoil dumping, and the slope is not treated by slope repair, which is very easy to cause soil erosion. According to the introduction of the IA Mr Pang, the contractor has been seriously criticized, requiring its rectification, strengthening the construction management and random destruction of trees is not permitted any more in the future.
JuanDa road is located on the opposite bank of Maxi River
2. H-steel reinforced pile slab retaining wall construction The section is adjacent to Maxi River, and there are small hydropower stations to be demolished below. Considering the characteristics of bedrock beneath the slope, H steel reinforced piles are used in the construction of pile-slab retaining wall. The disturbance to surrounding environment at the construction site is smaller and the site management meets the requirements, which has no effect on the vegetation and the Maxi River below.

. Construction site of H steel reinforced pile-slab wall 3. Jiayu Mining Section Jiayu Mining is a closed small pyrite mine. Its production office buildings and ore unloading facilities are located on both sides of JuanDa road, close to Maxi River. The slope of this section is steeper, runoff is larger in rainy days, and erosion is serious. Field observation found that the production of office buildings and other facilities are unattended, production has been suspended for a long time, surrounding and pavement scattered with cinder, slag sludge, pavement water and runoff can be visually detected a small amount of oil stains, roadside ditches seriously damaged, rainwater and sediment spilled into the Maxi River. At present, there is no road construction in this section.

80 ADB Chongqing Urban-rural Infrastructure Development Demonstration Project II - External Environmental Monitoring Report 4. Construction Section of Pile-slab Retaining Wall along Maxi River In the steep slope section above Jiayu Mining Section, along the side of Maxi River, there are hundreds of meters long piled-slab wall which will act as slope protection and river bank protection. At present, the basic foundation construction has been completed, and the construction formwork has not yet been dismantled. According to the site inspection, there is no construction camp on the site, and there are construction ramps on the river side, which have been leveled out, the site management is in order. There is no obvious sign of out-of-road disturbance and environmental damage. The IA manager said, in the rainy season of 2018, mountain flood broke out in this section. Because of the sudden and rapid onset of mountain flood, some gravel and materials on the river side were washed away, and the rural water pipeline near the downstream was damaged, resulting in complaints, which had been compensated after the flood. The damaged water pipeline had been repaired and moved to the opposite side of the river where it was originally located, and the water supply had not been affected after the restoration.

5. Temporary dump
There is a temporary storage yard at K5 where excavation waste generated by construction are stored. Site inspection found that the temporary storage site is located in the hilly plain, the terrain is relatively flat; the soil has been leveled, the height is low, the slope is gentle, there is no safety risk, serious erosion and soil erosion signs; but the dump site has not set up the necessary environmental protection facilities such as effective protection and interception drainage ditches, sedimentation tanks and so on. There are a small number of
81 ADB Chongqing Urban-rural Infrastructure Development Demonstration Project II - External Environmental Monitoring Report construction boards and dry latrines beside the existing highway. The IA indicates that a small amount of domestic sewage is transported to nearby villages for agricultural fertilizer.
Because it is located in Damu Nature Reserve and secondary water source reserve, the temporary dump site does not meet the requirements of relevant laws and regulations, and should be closed as soon as possible. According to contractor manager, the temporary discarded crushed stone and spoil can be used for subsequent road construction filling.
Temporary dump site 6. End of JuanDa Road The terminal of this project is connected to Damu Township. Some existing rural roads are seriously damaged. The construction has started, but it is only at the early stage of construction. There is no construction blocking, drainage interception and sedimentation measures are set up on site.

82 ADB Chongqing Urban-rural Infrastructure Development Demonstration Project II - External Environmental Monitoring Report II. Main Problems Existing and Suggestions for Rectification
Based on the on-site inspection and the analysis of the communication between the EMT and the IA and contractor, the following findings and problems can be summarized, and some suggestions and rectification measures are put forward. Some suggestions have been directly fed back to the representatives of the contractor on site.
1. Project progress:
Due to land acquisition, alignment changes and other reasons, the current construction progress is seriously lagging behind. Most of the construction personnel have been evacuated from the construction site due to approaching Spring Festival. The % of completion is about
17 %,
2. Environmental management and training:
Contractor has a clear understanding of the work background of the project, which is located in nature reserves and highly sensitive to the environment, but overall, there are many deficiencies in environmental protection training and environmental management system in the pre-construction stage of the project, they need more comprehensive environmental protection training. The environmental management system and full-time and part-time personnel are not perfect, and the environmental protection requirements and signs on site are not good.
It is suggested that comprehensive environmental protection training should be carried out as soon as possible after the start of follow-up construction, and all participating units should be urged to establish and improve the environmental management system, clarify their responsibilities and ensure that relevant management work is in place. Environmental protection management system and personnel responsibilities should be issued through official documents and paper and electronic documents should be retained.
Each participating unit shall set up environmental protection record, and keep the image data comparison before and after the project, the quantity record of completed environmental protection facilities and the text and image record of main facilities on the site. Environmental accidents and complaints arising in the construction process should be dealt with in time, and complete incident records should be kept. The contractor should improve the civilized construction and environmental protection signs.

3. Environmental sensitive zone protection:
JuanDa Road is not only located in the experimental area of nature reserve, but also part of the road section crosses the scope of drinking water secondary water source protection area. According to relevant laws and regulations, environmental impact assessment and EMP regulations, no dump sites are allowed in the sections crossing nature reserve and water source protection area, and sewage discharge is strictly prohibited in the water source protection area. The contractor must strictly implement relevant regulations and carry out comprehensive rectification. The local administrative department of environmental protection should be consulted as soon as possible for the protection of water resources protection zones.
The temporary dump site in the protected area should be relocated or used in filling as soon as possible. The environmental protection measures such as construction blocking, drainage ditch interception, sand sink, etc. should be set up. The waste water generated by the construction should be treated and reused for sprinkling water, dust removal, greening, etc. It should not be discharged out. The construction solid waste must be transported and disposed, and the discharge of sewage and waste into Maxi River must be strictly prohibited. Considering the irregularities of damaging trees outside the roadbed in the previous construction, the protection of plants must be emphasized in the follow-up construction, and the damage of trees outside the red line of road and temporary land must be strictly prohibited. 4. Coordination and management with related parties and facilities: (1) Coordination with Jiayu Mining Industry The houses and production facilities of Jiayu Mining are adjacent to JuanDa road. In addition to economic compensation, the houses and production facilities must be demolished for road expansion. The building waste, scrap metal, slag and oil pollution generated by demolition may cause pollution to the nearby Maxi River. It must be properly handled and transported out in time for disposal. (2) Coordination of reservoir diversion project
There is a Shuangjiang Reservoir diversion project near Damu town section of JuanDa road ( IA please check its construction schedule) implemented at the same time. Some of its construction sites are close to the ADB JuanDa road, which may overlap with JuanDa road construction behavior.. It might be difficult to distinguish the ecological damage and
84 ADB Chongqing Urban-rural Infrastructure Development Demonstration Project II - External Environmental Monitoring Report environmental pollution caused by the two projects. Therefore, the contractor should coordinate with other project implemented at the same time as possible, minimize the adverse environmental impact in the same construction area, and clarify their respective responsibilities. In actual construction, it is particularly important to clarify the scope of construction sites, especially temporary land. When conditions permit, temporary land for construction can also be shared, but it is necessary to clarify their respective environmental protection responsibilities.
3.8.2 Detection of Heavy Metals in Sediment of Rongfeng River in Rongchang
During the implementation of the Rongfeng River flood management sub-project, after drying, most of the river bottom silt removed was backfilled into the greening area of C03 of the project, and a few of the silt could not be used, which was transported by garbage trucks to the designated garbage dump in Rongchang District for landfill treatment in August 2017.
The detection report of the sediment of Rongfeng River is attached as AppendixI.
3.8.3 Water Source of Wanzhou Yangliu Waterworks Since the new water source transmission tunnel of Yangliu Waterworks has not been put into construction yet, the water source of Ganning Reservoir is being used temporarily at present, which is also the water source of existing Wanzhou Jiangbei Water Supply. The water quality monitoring report and records of Ganning Reservoir in 2017 and 2018 is as follows figures. It can be seen that the management of Ganning water resource is in order and complies with the national regulations.

4 CONCLUSION AND RECOMMENDATION
4.1 Conclusion
According to the above content, it can be seen that the environment management plans of the Rongchang Rongfeng River Flood Management Subproject, Wulong Wujiang Flood Management Subproject and Wanzhou District Yangliu Water Supply Subproject, Fuling and Shizhu road subproject and Chengkou County Urban-rural Road Network Improvement Subproject, during the civil engineering construction, have been basically implemented, which can be primarily presented by: 1. Institutional responsibility: all sub-projects have set up integrated environmental management institutions in accordance with EMP and clarified respective responsibilities and followed environmental management throughout the whole process; 2. Contractor’s obligation and performance: contractor accepts proprietor unit’s and supervising unit’s management during the construction; contractor and supervisor carry out internal monitoring regularly in accordance with requirements and submit supervising monthly report to proprietor; at the same time, strictly implement environmental alleviation measures according to EMP and continually improve and develop corresponding environmental alleviation measures. 3. Implementation of alleviation measures: according to site inspection, among all sub-projects under construction, WZYL, RCRF, WLWJ, CKLW adopted corresponding environmental alleviation measures according to EMP. Because FLLW just started, some environmental alleviation measures were not conducted good enough as required by EMP. 4. Monitoring plan and result: for subprojects under construction, WZYL carried out monitoring of all parameters in accordance with plan listed in EMP and results all meet related standards. Only monitoring of air environment did not implement in accordance with plan (only undertook monitoring at nearby sensitive points around construction sites); RCRF undertook monitoring of all parameters in accordance with plan listed in EMP to a large degree and its results all meet related standards while monitoring of air environment and surface water environment did not implement in accordance with the plan( air environment: only undertook monitoring at nearby sensitive points around construction sites; surface water: only select a monitoring point at downstream) 5. Training: during the reporting period, no intensive trainings were conducted by CPMO and
100 ADB Chongqing Urban-rural Infrastructure Development Demonstration Project II - External Environmental Monitoring Report
Consultants for IAs and PMO staff. It is emphasized that Fuling road contractor should strength the implementation of EMP. 6. Public Consultation and Complaints: after the notice of environmental impact assessment was conducted to the subprojects on the website of environmental protection agency during the early construction period, complaint organization and hotline were established in the primary department in the villages and towns of projects. Due to the restrictions, different forms of public consultations were conducted to the subprojects (such as Wanzhou, Wulong and Chengkou because subprojects were in the towns for construction where population was dense. Contractors would organize the neighboring residents to have an informal discussion occasionally and have notice about the construction situation of at the construction site and department of project. However, the population of subprojects along Shizhu and Fuling was relatively less. Thus, notice was only conducted to the construction site and project department). Complaint hotline was established in the primary government of subprojects. It was strictly conducted according to the requirement to deal with the complaint. From the current feedback result, the public of subprojects had supportive attitude to the implementation of projects. It was expected to finish the project as soon as possible so as to enlarge the beneficiary range. 7. Wulong subproject contractors of anchor cable anti-sliding wall has rectified the slurry discharge by setting up small sediment pools and further conveying solid waste to spoil ground. Shizhu contractors will remove the waste soil generated by roadbed land sliding ASAP from the valley to spoil ground. Fuling water transmission pipe damaged has been rebuilt in time in August 2018. Urge the IAs and PIUs to enhance the inspection on environmental management measures. In general, EMP and adverse environmental mitigation measures formulated at early stage have been implemented effectively and yielded good results. Most of the construction camps and construction sites are minimized from waste water, construction dust, smoke dust and noise disturbance and solid waste is discarded or discharged orderly. Construction sites and its surrounding environment are in good quality and complaints have not been received so far in terms of environmental pollution.

4.2 Recommendations
(1) Fuling Road Project is located in the nature reserve, while is adjacent to the Maxi River which is the secondary water source. The Fuling owners and environmental consultants should strengthen the training of the contractor on environmental protection policies and mitigation measures to ensure that the construction process in the next stage can be carried out in accordance with EMP. At present, the progress of the Fuling project is slow, only 17%. It is expected that after the Spring Festival of 2019, the large-scale construction of the retaining walls and bridges along the river will be fully carried out. At that time, environmental protection measures will be the key monitoring indicators. (2) Some indexes of surface water monitoring of Rongfeng River in Rongchang exceed the standard. Even it is nothing to do with ADB Rongchang subproject, but we hope that Rongchang IA could report this to Rongchang Government to take necessary action. (3) Some sub-projects materials are scattered and uncovered. It is suggested that site management be strengthened.
