1. INTRODUCTION
1. Hanoi Pilot Urban Railway line No.3 (Nhon – Hanoi Raiway Station) Project includes 9 construction packages, of which just packages CP04 (depot civil works) and CP05 (depot architectural works) are currently being under construction by Vietnamese contractors. The Packages CP01 (viaduct section) and CP02 (elevated stations) are in the process of the Contract negotiations, whereas the pre-qualification stage is about to be completed for the Package CP03 (underground works, line and stations). The remaining packages CP06 to CP09 related with equipment and systems are at different stages of their Technical Design.
2. Asian Development Bank (ADB), Agency Françoise de Development (AFD) and Direction Generable du Tresor et de la Politique Economique (DGPTE) have assessed and agreed to provide a loan for Hanoi Pilot Urban Railway line No.3 (Nhon – Hanoi Raiway Station) Project.
3. Socially the project will be a benefit to the population in the project area. The population, located in the western area of Ha Noi will, by using the metro: avoid traffic congestion and reduce safety hazards (especially traffic accidents); reduce health problems (especially respiratory problems) due to air pollution and dust; and save time and benefit from a good transportation alternative to go to Ha Noi Center.
4. Beside the benefits of the project also have negative impacts on the local environment. Therefore the project has environmental management plan The Environmental Management Plan (EMP) which had been implemented by the Contractors during the construction works as specified in Environmental Impact Assessment (EIA).
5. Implementation result report of environmental management plan of the project (environmental monitoring/test results, environmental quality observation results) is to present compliance with environmental protection commitment as specified in EPM and EIA of ADB.
1.1. Objective of report
6. Environmental monitoring report for the first semi-annual of year (from April to June 2013) will aggregate the environmental performance of Hanoi Pilot Urban Railway line No.3 (Nhon – Hanoi Railway Station) Project in general and environmental control activities, the environmental mitigation measures are applied to the construction bidding package. This report reviews the compliance of environmental activities with approved EMP by MRB and proposed newly mitigation measures if necessary in the next time in order to control and minimize negative environmental impacts.
1.2. Environment Monitoring Mechanism
7. The National Environmental Expert of IDOM was mobilized for semi annual environment monitoring of the civil works for April 2013 during one month from May to June 2013. To reviewed the activities of the contractors in the project sites in order to ensure compliance with Environment Management Plan (EMP) of the Project and ADB’s Social Safeguard Policy Statement 2009. Environmental Expert was accompanied by The staffs MRB, Environmental specialist, PIC’s preventatives and Environmental and safety manager of Contractors.
8. The Environmental Specialist of IDOM has been mobilized to manage environmental issues since April 2013. The main tasks of Environmental Specialist is Undertake monthly monitoring of the work of the PIC in supervising the overall implementation of the various EMP provisions and the environmental performance of the contractors (in terms of implementation of mitigation measures for the construction phase as specified in the EMP / EIA and site specific environmental management action plans).
PAGE 2
1.3. Environmental Management Plan (EMP)
9. CP04’s and CP05’s EMP (Environmental Management Plan) were included in the bidding documents of civil works during the procurement stage. The contractors were required to consider the requirements of the EMP when submitting their bids as the conditions in the EMP become contractually binding on the contractors. The contractor must be supplied these details and it was noted that all contractors have now supplied a EMP. Copies of these were reviewed and found to be satisfactory.
1.4. Site Environmental Compliance Inspection
10. These EMP are monitored and enforced by the Environmental specialist of IDOM who use checklists included in the EMP. By using the checklists consistency is maintained between the packages. The checklists are compiled every month (From May to June, 2013). The checklists had been filled in correctly and reporting was thorough. No environmental issues were identified. No complaints from villagers were reported about impact of dust, noise, vibration and water quality from construction works at the time of the inspection.

21. It is expected the signature of the contracts with the corresponding contractors of packages CP01 and CP02.
22. The package CP03 will see its prequalification stage finished.
2. COMPLIANCE WITH ADB LOAN AND APPLICABLE GOVERNMENT LAW REGULATIONS AND REQUIREMENTS
2.1. Situation of compliance with ADB loan
23. At present, additional Environmental Impact Assessment- ABD was developed completed by MRB. Basically, the updated Environmental Impact Assessment report – ADB has main content as given in EIA No.26194 August/2010 and just supplements, amends some legal documents on environmental protection stipulated by Vietnam, in which update of some newly- issued Vietnamese Code instead of old Vietnamese Codes and Vietnamese Standards without valid.
24. Three safety-monitoring levels are committed to be implemented in the Project: regular, periodical and public monitoring:
i. Regular monitoring is done by Construction Supervision Consultant (CSC). CSC shall bring monitoring results into project progress reports to be submitted to MRB and other relevant monitoring consultant/organizations. ii. Periodical monitoring (every month and every 6 months): is one part of the whole EMP supported by IEMC. The results shall be reported to MRB, ADB. iii. Public monitoring: the monitoring is implemented in accordance with regulations/procedure of Vietnam with technical and management assistance of MRB.
25. In accordance with regulations of ADB and Vietnam, contractors must implement EPM and SEP. Project progress for EPM and SEP is as follow:
PAGE 5
i. CP04, CP05 and CP01 include EMP into Bidding Document. EPM is developed by Systra. Environmental monitoring results show that content of EPM is not totally suitable with content of EMP given in EIA-2010, in particular, some detailed environmental management plans committed in EPM in EIA-ADB 2010 are not included into SPM at viaduct package (CP01) such as: public working safety plan and public health, chemical and oil leakage management plan, urgent response plan. ii. CP04 has completed 90% with application of the overall environmental monitoring system and direct monitoring in site of VINACONEX, CENMA. Regarding CP04, staffs in charge of environment are assigned as bridges for management and settlement of issues related to environmental sanitation and working safety between the CMC contractor and other relevant parties. Contractor of the package is Vinaconex. The Company has developed the EMP with supporting of SYSTRA (Project Implementation Consultant) and Hanoi Centre for Environmental and Natural Resources Monitoring and Analysis (CENMA) to implement environmental monitoring program. Detailed requirements in implementation of EMP were brought into bidding document and contract with Vinaconex. The contractor prepared and submitted EMP to MRB before construction time. During infrastructure (CP04) building, environmental monitoring activities are carried out by independent consultant. During construction of CP04, CENMA implements environmental quality monitoring activities. iii. Regarding CP05, HANCORP requested SYSTRA to develop EPM and SEP (ref. HPMLP/CP05). Environmental Management Plan was completed and submitted to MRB on 8/4/2013, but this time was late (4 weeks after construction). CP05 started since April, main items under CP05 have not been implemented by HANCORP. The Company signed the Contract with SYSTRA to implement the environmental management plan activities. iv. CP01, CP02 and CP03: are under bidding process.
26. Semi-annual report June/2013 based on the results of monthly environmental monitoring report at Depot site from May to June, 2013 (more detail the results of monthly reports at index 3 and index 4).
27. Grievance Redress Mechanism (GRM) i. In accordance with requirements in Protection Policy Statement of ADB (2009), MRB prepared one chapter of Grievance Redress Mechanism (chapter VIII in Environmental Impact Assessment Report of August 2010) in which the law, grievance redress, basis for the application of settlement of damages caused by activities, and monitoring of the Project was stated. GRM was presented clearly in accordance with Vietnamese regulations such as: - Meet requirements in accordance with regulations in item 8, article 20 of Environmental Protection Law passed on 29/11/2005 by the Socialist Republic of Vietnam - Meeting requirements of the Circular number 26/2011/TT-BTNMT dated 18/07/2011 of Ministry of Natural Resources and Environment stipulating in detail some articles of the Decree No. 29/2011/ND-CP
PAGE 6
dated 18/04/2011 of the Government which stipulates strategy environmental assessment, environmental impact assessment, environmental protection commitment; - Decision number 80/2005/QD-Tg of the Prime Minister on 18/4/2005 stipulating regulations for public monitoring - Decree no. 79/2003/NC-DP of the Government on democratic implementation regulations at public level; - Decision no. 34/2007/PL-UBTVQH11 dated 20/4/2007 of Parliamentary standing committee on implementation of democratic regulations at ward, commune level - Resolution no. 09/2008/NQLT-UBTWMTQVN of the Government- Vietnam Fatherland Front Committee dated 17/4/2008 on guidance of implementation of articles 11, 14, 16, 22 and 26 of democratic implementation at ward, commune and town level Besides, public consultation for environmental impact assessment of the project must satisfy requirements of safety, health and environment policy of ADB. ii. MRB and consultant have not developed GRM at project level The project commits to comply with Vietnamese law and issues relating to GRM; however, in accordance with ADB’s regulations, GRM at project level still needs to be implemented. At present, MRB is organizing GRM at project level with main contents as follows: When construction starts, contractors organize reception division to record claims. Claims (if any) of the public shall be reported to MRB by contractor within 24 hours. Contractor publicizes name and telephone number (including hot line) of reception staff. If claims are not settled at contractor level within 02 days since the date of claim letter, they shall be settled in accordance with compensation, claim mechanisms in legal system described in Environmental Impact Assessment report. iii. The fact shows that MRB has so far not received any claims (oral or written) on environmental issues of local residents and/or relevant parties as done package (CP04). iv. In coming months there shall possibly have claims of public on environmental issues in next packages. MRB shall follow Vietnamese law to review and settle them. Implementation measures shall comply with ADB’s policies.
2.2. Environmental compliance requirements situation of the Government
28. Project documents, letters relating to environment i. Environmental management plan was developed in three bidding documents (CP05, CP01, and CP02) of the project. Besides advantages of Environmental Management Plan, there are restrictions that should be overcome: Although environmental impact of packages is not similar, 3 environmental management plans have the same. In order to solve this problem, MRB submitted the final Environmental Management Plan guided by ADB to the Donors again on 20 June 2013. Due to the CP05 was signed between MRB and Contractor (HANCORP) it is under implementation. This modification was done as the Contract Appendix of CP05’s bidding document. The Contract of CP01 and CP02 has not yet signed between MRB and Contractors so all environmental compliance requirements of ADB cleared in EIA shall be included in EMP of each bidding contract. ii. CP-04 has completed 90% of the works, included list of environmental
PAGE 7
management plan contents.
29. For CP05’s EMP, after modification was done as the Contract Appendix of CP05’s bidding document which is approved by MRB.
30. The following are the environmental quality standards and regulations based on the Vietnam Standards promulgated by the Ministry of Science, Technology and Environment: i. QCVN 05:2009/BTNMT - National technical regulation on ambient air quality ii. QCVN 26:2010/BTNMT - National standard for Noise iii. QCVN 27:2010/BTNMT - National standard for Vibration iv. QCVN 08:2008/BTNMT - National standard for surface water quality v. QCVN 09:2008/BTNMT - National standard for underground water vi. QCVN 24:2009/BTNMT - National standard for waste water quality
31. Equipment certificates for compliance with National environmental specifications of CP05 has not checked yet because they stared to work on April and the construction work is Temporary work office of CP05 at the Depot site.
3. CHANGES IN PROJECT SCOPE
32. There are no changes in the scope as well as implementation items of the contract packages.
33. The project progress is generally as scheduled; however, the packages CP01 and CP02 were delayed for 1.5 to 2 months due to the Solar and Lunar New Years.
4. INCORPORATION OF ENVIRONMENTAL REQUIREMENTS INTO THE PROJECT CONTRACTUAL ARRANGEMENTS
34. Contract agreement, the manner in which EMP requirements are included in the contract agreements such as contract with contractors or other relevant parties.
4.1. Evaluation on function and responsibility of organization and implementation of environmental safety
35. MRB has considered and implemented environmental protection issues for project packages, including the construction and implementation of the general Environment Management Plan (EMP) and specific site environmental plan (SEP) as committed in the Environmental Impact Assessment report-ABD/2010. i. MRB’s main activities that are related to EMP activities include: - Establishing Environmental Committee which is responsible for ensuring timely implementation of EMP, including monitoring, reporting, and building capacity related to the safety - Assisting Construction Supervision Consultant (CSC) and concurrently responsible for monitoring the contractor’s implementation of environmental safety as part of the construction contract (this requirement will be included in the Terms of Reference (TOR of CSC); and - Employing competent local consultants as Independent
PAGE 8
Environmental Management Consultants (IEMC) to perform the task ii. MRB is responsible for ensuring that the related parts in the contract documents of the packages of the project items shall comply with the Environmental Management Plan (EMP) iii. MRB takes responsibility for contacting with agencies, local authorities and relevant units that are responsible for implementing and monitoring EMP, particularly with Department of Natural Resources and Environment and the wards and communes within the project area, for implementing EMP. iv. As for the monitoring of contractors’ activities, MRB shall be responsible for: - Checking the project implementation index related to environmental issues - Carrying out unscheduled examination to ensure the contractor is taking mitigation measures as specified in construction contract - Reviewing CSC’s periodical reports to ensure their compliance with mitigation measures v. MRB performed well in their role as a coordinator between the Environmental Supervision Consultant and Construction Supervision Consultant and the contractor in the environmental monitoring.
36. The contractors’ compliance with environmental protection regulations was assessed to be serious, which is detailed as follows: i. The construction contractor is responsible for all environmental activities specified in the contract between the contractor and the MRB. ii. The construction contractor is responsible for performing measures to mitigate environmental impacts and conforming to the EMP approved during the construction of the project’s packages. During the preparation of technical proposals, the contractor is allowed to study the EIA report and propose in their document an environmental management plan, including environmental protection and environmental impact mitigation measures in accordance with the Project’s approved environmental impact assessment report. However, since the EIA-ADB 2010 report must be revised and supplemented to be conformable to a number of Vietnam’s new environmental management regulations, the suitability of the EMP developed by the contractor (CP01, CP02, CP04 and CP05) is restricted. iii. The contractor prepared EMP. The contractor assigned their employee to manage environmental plan and labour safety. This employee directly carries out environmental mitigation and labour safety measures as specified in the approved environment plan. The environmental management plan of the Contractor was submitted to MRB and sent to CSC and IEMC for review. Changes (if any) shall be assessed in terms of feasibility and legally (laws, decrees, circulars and other regulations) before proper revisions are approved for specific cases at site. iv. As committed, the Contractor monthly submits progress reports enclosed with environmental sanitation and labour safety measures to the CMC and the Project Management Board. The results of observation of CP04 and CP05 at the Depot site likes that: - The contractor performs weekly inspection of the construction site to determine the compliance with environmental requirements - The contractor supervises once per month the implementation of EMP and the compliance with the environmental management plan.
PAGE 9
v. During the construction, the construction contractors received the coordination and supervision of MRB, CSC, Independent Environmental Supervision Consultant (Idom), environmental management agencies, and local community on the compliance with EMP.
37. Evaluation results for environmental monitoring activities of CMC shows that CMC has taken seriously the weekly and monthly monitoring reports on environmental sanitation and labour safety issues at site. Besides, CMC has also performed well its roles and functions in environmental monitoring, namely:
i. CMC (Construction Monitoring Consultant) acts as a direct controller and supervisor based on a mitigation plan that was made by the contractor and approved with relevant parties. CSC is responsible for monitoring the implementation of safety policies of the contractor during the construction process and GPM, including keeping track of the self-monitoring process of the contractor. CSC supports IEMC to collect and provide the information on environmental indicators at site and project implementation information; ii. CMC supervises the implementation of mitigation measures of the contractor, timely propose and implement mitigation measures to meet the safety protection requirements on the environmental management of the project; action plans/ emergency plans to cope with environmental issues, emergencies and losses that may occur during the construction. Each package is assigned to each direct supervisor at site who weekly assesses the effectiveness of labour safety and environmental sanitation measures at each site. iii. CMC takes part in weekly examinations and monthly supervisions and regular meetings co-organized by the project-related parties to provide the project implementation information and necessary working programs to raise awareness of the environmental protection during the project construction. iv. Monthly, CMC submits the progress report enclosed with environmental sanitation and labour safety measures of the packages to the Project Management Board. In addition, as problems arise, CMC sends directly a dispatch to notice the Project Management Board and related parties to solve together. The environmental monitoring forms were done fully by CMC and environmental impact mitigation measures were incorporated in the construction progress reports.
38. Implementation of EMP of CP04 and CP05
i. The EMP was developed by the contractor VINACONEX and approved by MRB and ADB. ii. The consulting firms performed regular environment monitoring. iii. During the construction, the Contractor strictly complied with the requirements on environmental protection. iv. There is no complaint from local residents about the waste impact on the air environment, noise and vibration pollution. v. There have so far been no any accidents at the construction site CP04 and CP05. The health care for labourers was contracted by MRB with the medical centre of Tay Tuu Commune. vi. However, the EPM content of the package CP04 still excludes some issues, namely: some items have not mentioned yet or not expressed specifically as in the environmental impact assessment report-ADB 2010 such as: workers’ camp
PAGE 10
management plan, labour safety and public health plan, and emergency response plan.
vii. The mitigation measures required in the EMP are being partially implemented by the Contractor during April to June, 2013. The average ratio of the measures effectiveness is between 2 and 3 (in accordance to ADB rating system). The overall evaluation of the mitigation compliance given by the Consultant would thus be Fair (graded 3 in the rating system).
39. The Contractor in charge of package CP05 (HANCORP) submitted the EMP to MRB on April 2013. But the content of the required mitigation measures in the CP05’s EMP in the bidding document is not consistent with the EMP included in the EIA cleared by ADB. Due to the CP05 was signed between MRB and Contractor (HANCORP) and its under implementation thus MRB, Systra and HANCORP modified EMP as the contents and format of ADB guided. This modification has done as the Contract Appendix of CP05’s bid document by Systra. On the other hand, CP05 just started their work on April 2013 and implementation progress has just constructed the temporary work office at the Depot of the CP05, this construction work is not effect to environment during this time. Monitoring of environment quality inside project area and its surroundings (the Depot site) in accordance with ADB’s and Vietnam’s regulations )
i. The package CP04 was contracted by the contractor with Hanoi Centre for Environmental and Natural Resources Monitoring and Analysis (CENMA) to observe/monitor environmental quality of the construction site and surroundings (According to the tendering schedule in the letter No.3277/QB-UBND dated July 5, 2010 by Hanoi City People's Committee). ii. CENMA carries out the environment quality monitoring within the project area and its surroundings from May 2012 to August 2013. Details are as follows: Keeping track of environmental indicators related to air quality, noise and vibration, water environment (surface water, groundwater) and soil quality via field surveys; locating sampling points; analysing and compiling monthly environment monitoring reports at three project areas (depot, viaduct, and tunnel). iii. Presently CENMA sent monthly reports to the MRB and the contractor on environment quality monitoring results at the Depot site from April to June 2013.
4.2. Outstanding issues of combining environmental requirements into contract agreement with contractors
40. Monitoring results shows that some requirements and impact mitigation measures proposed in the EMP by SYSTRA in the bidding document are still inconsistent with the requirements and mitigation measures in the Environmental Impact Assessment report- ADB/2010.
i. The inconsistence between the EMP by SYSTRA in the bidding document and the environmental impact assessment report-ADB/2010 causes difficulties to the contractor during their implementation of the environmental protection plan as well as their assessment of the package’s compliance with this plan. For example: For the packages CP01 and CP02, some specific environmental management plans which were committed in the EPM of EIA-ADB/2010 were not showed in SEP of the package CP01 (viaduct) and do not show requirements on: workers’ camp management plan; labour safety and public health plan; oil leakage management plan; and emergency response plan. ii. Besides, some impact mitigation measures stated in the environmental impact assessment report - ADB (February 2010) are not included in the EMP in the
PAGE 11
bidding documents of CP01 and CP02, such as air pollution and noise control measures during the construction; sediment control measures at Thu le Lake during the construction; measures to minimize social conflicts during the construction, etc. iii. In fact, to meet practical conditions, the EMP developed in the bidding document may be somewhat different from the commitments in the EPM in EIA. However, these changes need to be carefully considered on the basis that higher environmental protection effectiveness must be obtained and consent of Hanoi People’s Committee and MRB must be reached.
41. Although the packages CP01, CP02, CP04, and CP05 are different in construction, natures and level of impact, EPM and SEP contents are considered and assessed by ADB’s environmental experts to be similarly developed. This is not consistent with the reality as well as with the contents stated in the EPM in the report EIA-ADB 2010.
42. International consulting firms and other related agencies implement the environmental monitoring. However, the project environment monitoring at site has not been furthered implemented by the independent environmental monitoring consultant since April 2012.
i. Coteba, international independent environmental consulting company, recently named as Artelia Ville & Transport, already performed the environmental monitoring at the construction site for six months, from November 2011 to April 2012. ii. The main activities Coteba performed during the environmental monitoring at the construction site include: - Reviewing monitoring obligations stipulated in the Environmental Impact Assessment report - Reviewing the general environmental management plans (for example, strategic planning, specific environmental management plan namely dust control, noise control plan, etc.) developed by the construction contractor; monitoring the implementation of commitments to minimize environmental impacts defined in the EMP - Preparing the monthly environmental monitoring reports for MRB and related donors AFD and ADB - In addition, Coteba also provided for HRB’s assessment the terms of reference for air, water and land monitoring activities and the final implementation of CENMA along the railway iii. Since April 2012, the implementation of environment monitoring activities at the construction site by the international independent environmental consulting company has not been continued. Currently, Idom is continued the deployment of this content
5. SUMMARY OF IMPLEMENTATION OF ENVIRONMENTAL IMPACT MITIGATION AND COMPENSATION MEASURES
43. During the construction of CP04, the contractor observes strictly the requirements on environmental protection and waste management during the construction.
i. Dust pollution control: During dry days, water twice or thrice at the surroundings of residential areas and entrance road to construction site
PAGE 12
ii. Noise and vibration control: Noise and vibration level are lower than the allowable level in Vietnamese standards iii. Flood control and prevention: The structure plan is designed at the ground level from 0.8 to 1.0 m higher than the regional ground level. However, it does not cause inundation to residential areas and neighbouring farming areas since storm water is collected into the drainage system and flows into the lakes in the project area iv. Wastewater control: Domestic wastewater by officials and workers at site is treated by septic tanks. The construction site is equipped with two double toilets. Sanitary waste is treated by underground septic tanks v. Sewage from the construction site CP04 and workers’ camps flows along the southern boundary, adjacent to the Road 70 vi. Solid waste control: Daily solid wastes and solid wastes from buildings are collected into containers every day. Then they will be transported for treatment along with the city wastes by local hygiene team (contracted with the package) vii. Toxic waste management (mainly oil): Toxic solid wastes at the package CP04 are mainly stamps in small quantities. The management of toxic wastes in the package CP04 was well performed as committed in the EIA. Toxic wastes arising after each work shift will be collected in barrels for treatment (employing relevant units to collect and process waste in accordance with the Vietnamese provisions stated in the Circular 12/2011 on toxic waste management) viii. The contractor provides enough safety equipment for workers (protective helmets, clothing, and shoes, etc.) and requests them to use this equipment. The Contractor conducts a safety training program every two months for workers ix. Fire and explosion control: Keep only about 200 litres of oil at the construction site. Fuel for machinery and trucks must not be stored at the construction site but taken from the town's petrol stations (close to the project area) instead x. So far, there have been no fire and explosion accidents or incidents at the package CP04.
44. Waste management at workers camps
i. Environmental sanitation at workers’ camps: The contractor built nine worker camps in the area close to Hanoi University of Industry. Each camp can accommodate 30 to 40 workers. In peak construction months, more than 200 workers live in camps. ii. Workers camps are located at low-lying area that was levelled with sand. This is an important factor contributing to improving the sanitary condition. iii. However, the surrounding area of the camps still has stagnant puddles of wastewater, and the drainage without covers are not concreted and covered by grass, which causes unpleasant odours and creates favourable environmental conditions for flies and mosquitoes. iv. At the camps, water tanks (about 10 m 3) were built to store freshwater for workers to bathe and wash. However, these water tanks have not been used and become a place to keep stagnant rainwater and even wastes, which causes pollution and affects badly to landscape. v. There are only few pumps to supply water to the camps, and they are located in
PAGE 13
low positions. At worker’s camps, there are two drilled wells (30 to 40 m deep) to supply domestic water for workers. They will become overloaded if there are too many workers (over 70 people). Besides, the faucets are placed too low (less than 1 m from the ground), which causes dirty water splash into buckets and basins during water obtainment. Therefore, the faucets should be raised (approximately 1 m) for convenience and hygiene when used. vi. The package CP04 is coming to an end and under the completion stage, thus, there are not many workers living in camps. Therefore, environmental sanitation problems in camps may not be settled as a matter of priority. However, it is necessary to improve this issue if the package CP05 uses this area as camps for their workers. vii. At the camps, there are two public toilets with many rooms. viii. At the camps, there are two kitchens but no canteens. Food safety is performed well without diseases or cases of food poisoning due to unsafe food.
45. Overall evaluation of waste management measures in CP04
i. In general, the contractor performed well the pollution control and environmental protection measures during the construction. ii. However, a number of mitigation measures have not been fully applied namely solid waste control and environmental sanitation control in the workers’ camps.
6. SUMMARY OF ENVIRONMENTAL MONITORING
6.1. Compliance inspections
6.1.1. Summary of inspection activities
46. In accordance with the requirements of the EIA (August 2010), the Contractor in charge of the package CP04 (Vinaconex) submitted the corresponding EMP, which included the organization chart of the Environmental Unit of the Contractor shown in the figure below.

Figure 2. Organization for Environmental Management of CP05
i. VINACONEX is the contractor who submitted the overall environmental management plan (EMP). The contractor assigned an environmental health and safety team including 01 manager (Mr. Pham Dinh Khanh) and four environmental officials (EO) in charge of each construction item.
ii. The EMP of CP05 has to be noted that according to the conclusion given by ADB on 12 June 2013, the content of the required mitigation measures in the CP05’s EMP in the bidding document is not consistent with the EMP included in the EIA cleared by ADB. In order to solve this problem, MRB submitted the final Environmental Management Plan guided by ADB to AFD and other donors again on 20 June 2013. Due to the CP05 was signed between MRB and Contractor (HANCORP) and its under implementation thus MRB, Systra and HANCORP modified EMP as the contents and format of ADB guided. This modification has done as the Contract Appendix of CP05’s bid document by Hancorp and Systra.
iii. Regarding the Environmental Awareness, both Contractors are aware of the mitigation requirements and they are willing to implement them as instructed in the EMP. The Contactor of CP04 has the corresponding copy of the said EMP, whereas the Contractor of CP05 is waiting for the approval EMP. Both contractors agree to accept the regulatory requirements and their updates from time to time.
6.1.2. Compliance with impact mitigation measures
48. The Environmental Management Plan of the Contractor proposed specific environmental impact mitigation measures The Contractor’s compliance level with mitigation measures during their construction is monitored by the Consultant.
49. According to the observations made during April to June and to the information received from Vinaconex and Hancorp the Package CP04, CP05 complies with the mitigation measures during the construction. On the other hand, CP05 just started their work on April 2013 and implementation progress has just constructed the Temporary work office at the Depot of the CP05
i. Building materials are neatly gathered at the temporary storage areas in the project area, not hindering the remaining under-construction items. ii. The surrounding area of the construction site is fairly clean and neat. iii. The contractor complies with labour safety regulations. Storm water and wastewater canals of the project are carefully covered after the construction.
PAGE 15
iv. The storage system of building materials is carefully organized. v. The coordination between the contractor and MRB is regularly maintained so that environmental and labour safety issues are timely settled. vi. The environmental monitoring samples were fully prepared by CENMA and environmental impact mitigation measures were also incorporated into construction progress reports; vii. Trucks for soil and sand transport are carefully covered before departing construction site.
50. Outstanding issues:
i. Workers' camps do not meet the environmental sanitary requirements. Daily domestic wastewater of workers is directly poured into canals and ponds at the camps, which exposes potential risks of diseases.
ii. As the entrance road to construction site is relatively narrow and is overcrowded with residents on both sides, the contractor needs to increase watering to avoid dust when material trucks pass through.
iii. It is necessary to promote the contract signing to hire the disposal area for dumping mud and land which are still stored in the project
iv. Improve the efficiency of communication channels between the ward and contractor in supporting the locality to dig drainage channels in the residential area (outside the Project).
51. The EMP is included in the EIA and provides a comprehensive list of mitigation measures to be implemented during construction of the Depot. This list is a backbone for the environmental measures to be observed by the Consultant, and gathers the main activities to be monitored.
52. Monitoring results of compliance with environmental impact mitigation measures at the Depot site are evaluated in the Table below.

The mitigation measures required in the EMP are being partially implemented by the Contractor. The average ratio of the measures effectiveness is between 2 and 3 (in accordance to ADB rating system). The overall evaluation of the mitigation compliance during May to June, 2013 (Consultant has just mobilized since April so the consultant activities during the April focused on reviewed documents and the at-a-glance assessment of the environment surrounding of the Project site) given by the Consultant would thus be Fair (graded 3 in the rating system.)
6.2. Emission Monitoring Program (if related to or required in EMP)
6.2.1. Summary of monitoring results at the Depot site
54. Environmental Monitoring Program is proposed in the Environmental Impact Assessment and Environmental Management Plan. The contractor shall be responsible for complying with relevant regulations, and one of the monitoring tasks is to ensure the compliance with environmental regulations.
55. Emission Monitoring Program is implemented by CENMA at 4 monitoring points including 1 point of air environment quality, 1 point of noise level, 1 point of vibration; 1 point of wastewater.
6.2.2. Results
56. Summary of environmental quality monitoring results during the period from April to June 2013
i. Air Pollution The monitoring point KXQ1 (Located in the North-eastern corner of Depot) has good ambient air quality, the parameters for ambient air monitoring are lower than the allowable limits in the National Regulation (QCVN 05:2009 -
PAGE 20
Vietnamese Code on Ambient Air Quality). ii. Noise and vibration Noise monitoring results are also made at the monitoring site of KXQ1 as for the air environment. Equivalent sound level measured from 6 am to 9 pm ranges between 51.6 and 61.7dBA, higher than the allowable limits at some of the measurement periods. 31/48 measurement times (64.6% of the total measurement times) on January, 20/48 measurement times on February (42% of the total), 30/48 times (62.5% of the total) on March, 25/48 times (52% of the total) on April, 23/48 times (48% of the total) on May and 27/48 time (56% of the total) on June 2013. iii. Vibration at Depot Vibration acceleration measured from January to June 2013 varies from 33.7 to 47.6 dB, lower than the allowable limit in the National Regulations of Vietnam (75 dB). iv. Wastewater Coliform parameter is 2.4 times higher than the National Regulations of Vietnam 14: 2008. Other parameters are all below the allowable limit of the Regulation.
6.2.3. Evaluation
57. The pollution level should be compared with the relevant emission standards and/or the performance indicators noted in the EMP. All excessive pollution needs to be considered and monitored. In addition, the emission level can be compared with basic conditions (if the database is available) and described about the quality or evaluated on the base of ranking system as follows: 1. Very good. 2. Good. 3. Average. 4. Not good. 5. Bad.

6.3.1. Summary of environment monitoring activities
58. Surrounding environment Monitoring Program is implemented by CENMA at 5 monitoring points including 1 point of air environment quality, 1 point of noise level, 1 point of vibration; 1 point of surface water, 1 point of underground water. Specific information about the monitoring points is shown in the table.
6.3.2. Results
59. Summary of environmental quality monitoring results from January to June 2013
i. Air pollution The monitoring point of KXQ2 (West of Depot, at the main entrance and about 10 m away from Road 70) has signs of pollution. The total suspended particulates (TSP) in some measurement periods exceed the allowable limits in the Vietnamese standard: 1.04 to 1.11 times higher than the allowable limits. Benzene concentration parameters during some measurement also exceeded the allowable limits in the Vietnamese Standard, 1.01 to 1.08 times higher. Dust concentrations PM10 and PM2.5, lead dust cannot show the pollution level specifically because Vietnam does not currently have standards for the comparison (within 1 hour). In summary, the ambient air quality during six months including January to June 2013 showed the monitoring point of KXQ2 had signs of dust pollution (TSP), benzene. CENMA explains that the reason is due to direct impacts from the transport activities on the construction site and the Road 70. ii. Noise Equivalent sound level measured from 6 am to 9 pm ranges between 51.6 and 61.7 dBA, higher than the allowable limits at some of the measurement periods. 31/48 measurement times (64.6% of the total) on January, 20/48 measurement times on February (42% of the total), 30/48 times (62.5% of the total) on March, 21/48 measurement times (43.5%) on April, 23/48 measurement times (48%) on May and 22/48 measurement times (46%) on June 2013. iii. Vibration Vibration acceleration measured during three months from January to June 2013 is from 33.7 to 47.6 dB, and lower than the allowable limit in the National Standard of Vietnam (75 dB). iv. Surface water The monitoring results of lake water in Depot on January 2013 show that the lake is contaminated in comparison with the required standards. The oil content (Jan/2013) is 5 to 6.1 times higher than stated in 08:20081 BTNMT. Nitorit content is 2.9 to 3.1 times higher than stated in 08:20081 BTNMT. Finally, COD content is 1.03 to 1.7 times higher than stated in 08:2008 BTNMT. According to CENMA, the reason is that the lake water has remained stagnant for a long time. In February, March and April 2013, Hanoi Centre for environmental and natural
PAGE 22
resources monitoring and analysis did not take samples because the lake water in the Depot was being suck dry for the dredge. v. Groundwater The monitoring results of groundwater during three months including January, February and March 2013 showed that the groundwater was contaminated with Ammonium, specifically 1.9 to 2.2 times higher on January 2013; 5.7 to 5.2 times higher in February 2013, 1.6 to 1.8 times in March 2013, and 2.4 to 2.5 times in April 2013. On February 2013 alone, the observation results also showed that the groundwater was polluted with Manganese (1.59 to 1.62 times higher than the allowable limits).
6.3.3. Evaluation
60. The pollution level should be compared with the relevant emission standards and/or the performance indicators noted in the EMP. All excessive pollution needs to be considered and monitored. In addition, the emission level can be compared with basic conditions (if the database is available) and described about the quality or evaluated on the base of ranking system as follows: 1. Very good. 2. Good. 3. Average. 4. Not good. 5. Bad.

6.3.4. Overall evaluation of the environmental quality monitoring activities by CENMA
61. Environmental Monitoring Program is proposed in the Environmental Impact Assessment and Environmental Management Plan. The contractor shall be responsible for complying with relevant regulations, and one of the monitoring tasks is to ensure the compliance with environmental regulations.
PAGE 23
i. The Promoter selected CENMA to perform the environmental monitoring of air, noise, vibration and water environment, including such items Depot, viaduct and tunnel construction site. ii. CENMA is a unit directly under the Hanoi Department of Natural Resources and Environment. The environmental monitoring results were performed through monthly reports by CENMA including the following contents: Providing monitoring results of the month, assessing the monitoring results and proposing measures on environmental impact mitigation caused by construction activities of the project (if any), planning the implementation of monitoring for the next month to propose MRB and related parties for the approval. iii. CENMA laboratory is equipped with modern and suitable equipment for sampling and analysis activities of environmental quality. Laboratory officials are qualified and experienced in the field of environmental monitoring and supervision. iv. Environmental Monitoring Program is proposed in the Environmental Impact Assessment and Environmental Management Plan. The contractor shall be responsible for complying with relevant regulations, and one of the monitoring tasks is to ensure the compliance with environmental regulations. v. CENMA provides environmental monitoring data, which was measured, analysed and reported monthly during the period from May 2012 and expected to August 2013. vi. The compliance with requirements on the measurement points as well as monitoring parameters in Depot is defined in the Environmental Impact Assessment and Environmental Management Plan (Chart of monitoring points in Depot is shown in Appendix).
62. CENMA provides environmental monitoring data, which was measured, analysed and reported every month during the period from May 2012 and (expected) to August 2013. Currently, only two packages (CP04 and CP05) are being implemented, so this report only uses the measurement data in Depot.
63. The compliance with requirements on the measurement points as well as monitoring parameters in Depot is defined in the Environmental Impact Assessment and Environmental Management Plan (the chart of monitoring points in Depot is shown as Index 1 and Index 2)).
64. CENMA supplemented more and more specific monitoring components than EIA- ADB/EPM
i. According to EIA-ADB, the environmental components that are not monitored include surface water, environment and wastewater. ii. These two environmental components were monitored and supplemented by CENMA. This supplementary wastewater monitoring activity is appropriate. iii. The lake (with area of 15.7 ha) within the construction site is selected as a surface water monitoring point. Due to being under the excavation and embankment construction, the water source here is unstable. Thus, there are no monitoring data for some months when the lake has no or very little water, no surface water in natural conditions.
65. Observation parameters
i. CENMA selected more parameters to monitor than the requested by EIA-ADB. Parameters for the atmosphere: O3, total dust, dust Pb, Benzen. For surface

water: pH, DO, SS, COD, Bods (20°C), Ammonium, Nitr ite, Nitrate, Phosphate, oil, Chloride, Fluoride, Cyanide, Arsenic, Cadmium, Pb, Cr III, Cr VI, Cu, Zn, Nickel, Fe, Hg, Aldrin, Dieldrin, Endrin, BHC, DDT, Endosunfat (thiodan), Lindan, chlordane, Heptachlor, Paration, Malation, etc. ii. These parameters were selected to monitor the package because they are appropriate to the environmental standards issued in Vietnam. iii. For groundwater environment: pH, hardness, total solids, COD (KMnO4), Cl -, F -, - - 2- - NO 2 , NO 3 , SO 4 , S , Phenol, α total radioactivity and E. coli (Table below).

Examination of compliance and surrounding environment
68. Comparison Standards
i. Environmental monitoring activities are performed by CENMA in compliance with the current standards and regulations of Vietnam (regulations on receiving, preservation, transportation, sample analysis). ii. Comparison Standards on are based on the current Vietnamese Code. iii. Several monitoring parameters is not currently prescribed in the Vietnamese Code, therefore; the monitoring results are only informative, namely: Dust parameter PM10 and PM 2.5, Pb dust. iv. Besides, it should be noted that QCVN 24:2009/BTNMT – Vietnamese Code on wastewater quality is now amended into QCVN 40:2011/BTNMT. CENMA needs to consider this appropriately.
6.4. Monitoring Plan
69. Activities proposed to be implemented in the next 6 months:
i. Periodic monitoring at works site ii. Monitoring of the tasks of the PIC in the general implementation of the regulations, according to the EMP and to the environmental protection activities of the contractors of CP02, CP04 and CP05 by Consultants. iii. Ensuring regulations in the EMP (mitigation, monitoring, reporting etc.) to be conducted comprehensively and timely and in accordance with the approved budget in the EMP iv. Coordinating with CENMA to assess the quality of the surrounding environment, including the monitoring plan of the package CP02 (elevated station) - pre- construction period v. Monitoring plan of the package CP02 (elevated station) - pre-construction period vi. As scheduled, eight (8) environmental monitoring points will be performed at eight (8) locations, including five (5) air monitoring locations, two (2) surface
PAGE 26
water monitoring locations and one (1) groundwater. vii. As proposed by CENMA, the position NM2 is replaced to suit practical conditions. According to the ToR, the position NM2 is located at the interchange between the viaduct line, national railway and beltway for the priority 3. However, during the survey, CENMA did not find a suitable position. Therefore, CENMA proposed to choose a monitoring point of surface water for the replacement. About 100 meters far from Cau Giay Street in the Northeast, at the lake of the Party Committee of Cau Giay because this monitoring point is located near the viaduct construction line. viii. CENMA selected more parameters to monitor than those required in the EIA- ADB. The parameter for the atmosphere: O3, total dust, dust Pb, Benzen; For surface water: pH, DO, SS, COD, Bods (20°C), Ammoni um, Nitrite, Nitrate, Phosphate, oil, Chloride, Fluoride, Cyanide, Arsenic, Cadmium, Pb, Cr III, Cr VI, Cu, Zn, Nickel, Fe, Hg, Aldrin, Dieldrin, Endrin, BHC, DDT, Endosunfat (thiodan), Lindan, chlordane, Heptachlor, Paration, Malation, etc. ix. These parameters are selected to monitor the construction package performance because they are appropriate to the environmental standards issued in Vietnam. x. The selection of the parameters of chlorinated organic plant protection chemicals to monitor the surface water for the package CP04 is not necessary, may be cancelled.
7. OUTSTANDING ENVIRONMENTAL ISSUES AT THE METRO LINE 3
7.1. The existing big environment problems are determined
70. For example, non-compliance with loan covenants, EMP and / or environmental requirements of the government, inappropriate environmental pollution mitigation measures or incidents, accidents etc.
i. Surface water is monitored to have a total Coliform content higher than the allowable limit. ii. Wastewater is monitored to have a total Coliform content higher than the allowable limit. iii. Currently there are some stagnant puddles of water at worker’scamps. They may become a hazard to the health of workers there. iv. A part of wastes at camps that was thrown into the surroundings may become a hazard for the health of workers here. v. Cooking activities at workers’ camps may cause fire and explosion.
7.2. The solutions and corrective action plan
71. Showing clearly corrective action plan is implemented to address non-compliance issues and identified problems. The Action Plan includes specific actions to solve problems, people who are responsible for the implementation of measures and duration/ targets to execute and complete necessary measures. The Action Plan can be expressed in the form of table/ matrix (below). The timeframe and responsibility to report the progress of Corrective Action Plan to ADB should also be mentioned in this part.

Claims (if any) of the public shall be reported to MRB by contractor within 24 hours. Contractor publicizes name and telephone number (including hot line) of reception staff. If claims are not settled at contractor level within 2 days since the date of claim letter, they shall be settled in accordance
PAGE 34
with compensation, claim mechanisms in legal system described in Environmental Impact Assessment Report.
9. CONCLUSIONS AND RECOMMENDATIONS
9.1. Overall progress of implementation of environmental management measures
92. The packages CP04, CP05, CP01 and CP02 have included EMP into the bidding document. The EPM is prepared by Contractors and supported by Systra.
93. The CP04 has been so far completed 90% of the works with the application of the general and direct environmental monitoring systems in the construction site of VINACONEX, independent consultant and CENMA.
94. Regarding CP05, HANCORP Contractor has already requested SYSTRA, to prepare EPM and SEP (construction package ref.: HPLMLP/CP05). The environmental management plan was completed and submitted to MRB on April 8, 2013. However, its preparation and submission to MRB was late (four weeks after the commencement of the construction). However, the content of the required mitigation measures in the CP05’s EMP in the bidding document is not consistent with the EMP included in the EIA cleared by ADB. In order to solve this problem, MRB submitted the final Environmental Management Plan guided by ADB to the donors again on 20 June 2013. Due to the CP05 was signed between MRB and Contractor (HANCORP) and its under implementation thus MRB, Systra and HANCORP modified EMP as the contents and format of ADB guided. This modification has done as the Contract Appendix of CP05’s bid document..
95. The compliance with environmental requirements of CP04 and CP05 is satisfying level. It may be considered that conditions on the depot site are most probably much easier to handle in terms of environment and safety than what is anticipated on the construction sites along the metro Line 3. So, for the environmental and safety management of CP01 and CP02 the difficulties to be faced later on (which will definitely be a higher) must be thoroughly estimated
96. The monitoring activities of the Project’s GRM was shown in the Environmental Impact Assessment (EIA) by ADB 2010. Currently MRB and the Consultant are preparing GRM for the Project. MRB has so far received no complaints (in either oral or written forms) on environmental issues.
97. Hanoi Centre for Environmental and Natural Resources Monitoring and Analysis (CENMA) performed the monitoring/supervision of environmental quality at the construction site and the surrounding environment of the Depot site (including CP04 and CP05). CENMA sent MRB and the Contractor monthly reports on the quality monitoring results of the environment from May 2012 to June 2013.
98. There have been no environmental incidents or environmental complaints during April to June at the Depot construction site.
9.2. Identification of problems and solutions
9.2.1. Conclusion
99. Air pollution at KXQ2 (the gate of the Project area – near Road No.70). Solution: Increasing water spraying to reduce dust. 100. The environmental sanitary conditions at camps are not good. Solution proposed: Organizing public cleaning at camps. However, this activity has not been frequently held.
PAGE 35
101. The total value of coliform in the surface water of the neighbouring area and in the domestic wastewater under the CP04 is higher than the allowable standard. Solution proposed: Completing the lake digging and improving environmental sanitary conditions at workers’ camps. 102. The drainage system at the worker camps under CP04 is presently stagnant. Solution proposed: Dredging and picking up coarse waste from the drainage system to be immediately and frequently implemented during the construction. 103. Waste at the workers camp under the CP04 is partially dumped into the surrounding environment, which can threaten the workers’ health. Solution proposed: Cleaning the camps/to be immediately implemented. Cooking at the workers camp under the CP04 can cause fires and explosions. Solution proposed: Increasing the workers awareness and preparing regulations for workers. 104. The residential area outside the CP04 may be flooded in heavy rains due to its low elevation. Solution proposed: The Project should work with the locality to assist them to dig drainage canal for this area (outside the Project area). 9.2.2. Adjustment of monitoring (proposed based on monitoring experience/relevant trends) 105. Environmental specialist (Idom) inspection continuing the levels of compliance of the applicable mitigation measures at the construction site for the whole Metro line 3 project until June 2014. 106. Some impact mitigation measures stated in the environmental impact assessment report - ADB (February 2010) are not included in the EMP in the bidding documents of CP01 and CP02, such as air pollution and noise control measures during the construction; sediment control measures at Thu le Lake during the construction; measures to minimize social conflicts during the construction, etc. MRB has been solved and completed EMPs. 9.2.3. Recommendations 107. The compliance with EMP should be weekly or monthly monitored by environmental specialist. MRB should continue to request the Contractor to take effective measures in order to carry out the environmental monitoring plan as supported by the PIC (SYSTRA). 108. For new construction packages, MRB should request that feasible mitigation measures mentioned in the EIA report-ADB (February 2010), which are included in the bid price and contract documents, must be applied. 109. MRB should consider EMPs in the EIA Report by ADB, which are incorporated in the bid invitation for all civil structures under Hanoi Urban Railway Line 3. MRB should consider and request the contractors to follow EMP regulations to minimize adverse impacts on the environment. 110. Workers of the construction contractors have to be better trained on their roles in environmental safety and on the compliance with environmental impact mitigation measures during the construction. It is them who are primarily responsible for the compliance with the EMP regulations of the construction contractor. 111. For CP05, MRB should consider on worker camps because worker camp area is a lower lying than the Depot site about 1 m, this area is permanently submerged with stagnant water during rainy season. 112. The contractor needs to pay more attention to the worker camps and their sanitation to avoid insanitation and diseases when the hot season comes. The sewerage canal behind the workers’ camps should be dredged to improve the landscape and eliminate unpleasant odour. Nylon waste at stagnant pools around the workers’ camps should be picked up, and these pools should be levelled with sand. The waste management in the workers’ camps needs to be improved. Each camp should assign a worker to involve in cleaning around their camps once
PAGE 36
or twice a week. Cooking in camps should be forbidden, and joint cooking area for each worker team should be specified. Since the camps use underground water, the Contractor and CMC should pay attention to measures to fill up the wells after the construction so as to avoid polluting underground water; 113. It is necessary to enhance the capability of MRB staff and relevant individuals and organizations who are involved in the survey, to study on monitoring environmental safety in foreign countries with similar projects.
