1. INTRODUCTION

1. Hanoi Pilot Urban Railway line No.3 (Nhon – Hanoi Railway 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 CP02 (viaduct section) is is inaugrated at 27 May, 2014. The Contractors of CP04 and CP05 is Vietnamese company. CP01 (viaduct section – DEALIM contractor) was signed on February 2014 and on going to implement. Package CP02 (elevated stations) is being constructed at 5 stations, from No.1 to No.5. Concerning Package CP03 (underground works, line and stations), MRB sent bidding documents to ADB asking for comment. The remaining packages CP06 to CP09 related with equipment and systems are at bidding documents completion stage of their Technical Design, in which, CP09 is on detailed design phase.

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 the Environmental Management Plan (EMP) which had been implemented by the Contractors during the construction works as specified in Environmental Impact Assessment (EIA 8/2013).

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 of ADB cleared EIA 8/2013.

1.1. OBJECTIVE OF REPORT 6. The National Environmental Expert of IDOM was mobilized for the first semi annual environment monitoring of the civil works from January to June 2014. 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 on June 2009. This independent Environmental Expert was accompanied by the staff of the MRB, Environmental specialist (environmental supervisor), PIC’s preventatives and Environmental and safety manager of Contractors.

1.2. ENVIRONMENT MONITORING MECHANISM 7. The National Environmental Expert of IDOM (Support for Investment Owner on Project Management) was mobilized for semi annual environment monitoring from January to June 2014 of the civil works to review 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 of MRB, Environmental specialist, PIC’s repreventatives and Environmental and safety manager of Contractors.

8. The Environmental Expert of IDOM has been mobilized to manage this third Semi-annual Environmental Report. The main tasks of Environmental Expert is undertake monthly monitoring of the work developed by the Construction Companies for all the Packages 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).

1.3. ENVIRONMENTAL MANAGEMENT PLAN (EMP) 9. CP01’s, CP02’s, CP03’s, 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 an EMP. 10. Compliance with the environmental protection requirements that are specified in the report on environmental impact assessment (EIA) 8/2013 which cleared by ADB. The construction contractors CP04 and CP05 are committed to implement through the environmental management plan (EMP). For the CP02, Posco has developed EMP at construction site based on bidding documents and version 5 approved by PIC. Currently, CP02 is waiting for the Systra (PIC) to re-evaluate the content of EMP.

1.4. SITE ENVIRONMENTAL COMPLIANCE INSPECTION 11. 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 had been filled in correctly and reporting was thorough with ranking from 1 (very good) to 5 (very poor) as ADB’s standard ranks. The overall evaluation of the mitigation compliance from July to December 2013 of CP04, CP05 and No2 Station of CP02 constructed works given by the Consultant would thus be above fair (graded 2 in the rating system).

12. There have been no environmental incidents or environmental complaints from any residents were reported about impact of dust, noise, vibration and water quality from construction works at the time of the inspection at the Depot and viaduct construction site. Dates of actual site inspection/environmental monitoring activity conducted by Environmental Expert and Environmental specialist for the period from January to June 2014.

2. COMPLIANCE WITH ADB LOAN AND APPLICABLE GOVERNMENT LAW REGULATIONS AND REQUIREMENTS

2.1. SITUATION OF COMPLIANCE WITH ADB LOAN 24. Based on the Safeguard Policy Statement, June 2009 of ADB, three safety-monitoring levels are committed to be implemented in the Project: regular, periodical and public monitoring:

i. Regular monitoring is daily monitoring task, which is done by the supervior consultants and supervisor contractors. The PIC has daily on-site visits. If they notice about any Environment problem, they immediately inform to MRB and instruct the contractor to follow EMP which signed between them and their sponsor.

ii. Periodical monitoring is a weekly monitoring task carried out by the Environment Specialist of IDOM. The results/analysis of these visits are included on the monthly reports) which are submitted to the MRB. In its scope of the works are included the following tasks:

To undertake monthly monitoring of the work of CENMA in supervising the overall implementation of various EMP provisions and the environmental performance of contractors (in term of implementation of mitigation measures for the construction phase as specified in the EMP/ EIA and site specific environmental management action plans).

To supervise the on-site ambient monitoring conducted by CENMA and review the results of ambient monitoring.

iii. Public monitoring is the semi-annual external monitoring carried out by the Independent Environment Expert of IDOM in accordance with regulations/procedure of Vietnam with technical and management assistance of MRB. In its scope of the works are included the following tasks:

Together with the Environment Specialist, undertake the initial monthly monitoring and subsequent semi-annual monitoring of the over-all implementation of various EMP provisions and the environmental performance of 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. All the measures have to be in accordance with the Environment Management Plan (EMP) of the Project and ADB’s Social Social Policy Statement 2009.

During the initial monthly monitoring, train the ES on the conduct of monthly monitoring and monthly report preparation.

To provide guidance to the ES to ensure that monthly monitoring and report preparation are done properly and in time manner.

To prepare semi-annual monitoring reports based on the findings of the monthly monitoring activities and results of quality parameters monitoring.

To review and approve the environmental management action plans/specific environmental management plans (e.g., Spoils Disposal Plan, Dust Control Plan, Noise Control Plan, etc.) to be prepared by contractors as specified in the EMP. Ensure that such plans are not in conflict with the provisions of the EIA/ EMP.

To provide training to MRB staff and undertake environment management capacity building for MRB.

155

To interview the surrounding people at the construction site to identify how is the construction works impact.

25. In accordance with regulations of ADB and Vietnam, contractors must implement EMP, policies and regulations listed in Part II - Policies, Law Frames and Administrative formalities of EMP report up dated to 2012 (From P16 to P21 – EMP Report). Project progress for EMP is as follow:

i. The Package CP01 completed process of the “Contract Negotiations” with the contractor DAELIM and the contract was signed on 11 April 2014. Document and procedures are under accomplishing to carry out the construction. Safety plan have been sumitted to MRB and waiting for construction at P345 – from station No.1 to station No.2 (Posco).

ii. Systra has approved the version 5th of Posco’s EMP based on bidding documents. Currently, the contractor has been effeciently implementing the plan, excepting to meet more effectively GRM mechanism by supplying more detail information to the people (to be more clarified in the next part).

iii. Regarding to the Package CP03 (Tunnel and underground stations), MRB has sent bidding documents to the ADB for comments and preparing for open bidding.

iv. The Contractor in charge of the package CP04 (VINACONEX) submitted the Environmental Management Plan (EMP) to MRB and completed main activities of the package CP04 at the Depot site complying with the environmental impact mitigation measurements as mentioned on the CP04’s EMP conforming to monthly consultant’s evaluation on environment at annex No.5.

v. The Contractor in charge of the package CP05 (HANCORP) submitted the EMP to MRB on April 2013 and the Contract Addendum No 01/PLHD-TCXD signed on 30th

October 2013. The contents on EMP have been approved and noticed to construction staffs and construction workers in October 2013 (Annex: Evaluate EMP implementation of contractor CP05). However, the constructor has not carried out works yet, thus, need to supplement lacking items at site for the next construction.

26. The Semi-annual report corresponding to the months of January - June 2014 is mainly based on the Monthly Environmental Monitoring Reports at Depot and Station No.2 (Viaduct station). The overall evaluation of the mitigation compliance given by the Constractor would thus be fair (graded 1-2-3 in the ADB rating system suggestion). For more details, additional information has been included on the Annex 4: Mitigations Measures Required in EMP from January to June 2014 at Depot Site (CP04 and CP05) and the Viaduct Stations (CP02).

27. Grievance Redress Mechanism (GRM):

i. In accordance with requirements in Safeguard Policy Statement of ADB (2009), MRB prepared one chapter of Grievance Redress Mechanism (chapter VIII in Environmental Impact Assessment Report of August 2013) 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 dated 18/04/2011 of the Government which stipulates strategy environmental assessment, environmental impact assessment, environmental protection commitment;

155

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.

ii. Besides, public consultation for environmental impact assessment of the project must satisfy requirements of safety, health and environment policy of ADB.

iii. MRB and consultant have not developed GRM at project level. However, project has applied this mechanism in other management model: Safety and environment Managers of CP02, CP04, CP05 take responsibility to be as a conection to control and settle public hygiene, safety at work between contractors and related parties. Other hand, supervisor groups from MRB have to supervise these matters at Employer ranking and commit to tackle process as others technical problems (based on terms of the Contract, plan, engagement, policies and applied regulations).

iv. The project commits to comply with Vietnamese law and issues relating to GRM; and, 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 process 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. At site, contractors have announced informations on: project, ground erea, employer, consultant, and contractor (main and sub) but has not yet set up a hotline and title of the person in charge. However, these informations can be collected at entrance of site hut. Apart from that, Project manager arrange a link with public media to provide information of the project’s progess and content to resident as well as community consutation.

v. 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 at all packages (CP02, CP04, CP05). Regarding to cutting down ancient trees at Kim Ma street matters, it should be arranged a community consultation to find out best solution. Revelant including: Surrounding resident, Hanoi green tree company, Hanoi authority agencies, MRB, sponsor and consultant shall make toghether final decision based on public benefit.

vi. In coming months there shall possibly have claims from the public part on environmental issues in the next time. MRB shall follow Vietnamese law to review and settle them in priority. Implementation measures shall comply with ADB’s policies.

2.2. ENVIRONMENT COMPLIANCE REQUIREMENT OF THE GOVERNMENT 28. Following approved project’s EMR, Part II (policy frame, law and administrative formalities) is fully listed legal regulations and updating to 2012. At present, the new Law on Environmental Protection was passed by Congress, and the project will be carried out in accordance with this new version, Law No. 55/2014/QH13, which will came into force on 1st January, 2015. 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 05:2013/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

Besides those stipulations, contractor need to comply regulations on environment management, safety at work in current effective and commited plan.

29. The Supervision Consultant has checked the equipment certificates for compliance with National environmental specifications of Contractors Vinaconex, Hancorp, and Posco. Those certificates of the contractor of CP02 and CP05 are attached at the Annex 5. However, they have not been put into operation status for almost 5 months.

155

3. CHANGES IN PROJECT SCOPE

30. There are no changes in the scope as well as implementation items of the contract packages.

31. The project implementation is slow in comparison with the tentative schedule due to reasons from 2013 as: the progress CP04 is slow caused by the delay of land clearance; the progress of CP05 is delayed due to the staffing matter of contractor, it is unstable, work control process has not satisfied, besides that, contract between MRB and Systra have not been timely extended so that construction progress was delayed over 3 months.The CP02 has just started/commenced since August 2013, the main construction works have not been constructed yet so just focus on bored pile thus progress is stable.

155

4. INCORPORATION OF ENVIRONMENTAL REQUIREMENTS INTO THE PROJECT CONTRACTUAL ARRANGEMENTS

4.1. EVALUATION ON FUNCTION AND RESPONSIBILITY OF ORGANIZATION AND IMPLEMENTATION OF ENVIRONMENTAL SAFETY

32. MRB has considered and implemented environmental protection issues for project packages, including the construction and implementation of the general Environment Management Plan (EMP) as committed in the Environmental Impact Assessment report-ABD/8-2013.

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 Project implementation Consultant (PIC) 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); and

Employing competent local consultants as Independent Environmental Management Consultants 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 in Hanoi 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 periodical reports to ensure their compliance with mitigation measures of contractor

v. MRB performed well in their role as a coordinator between the PIC and IDOM and the contractors in the environmental monitoring.

33. The contractors’ compliance with environmental protection regulations was assessed to be serious, which is detailed as follows:

i. The construction contractors CP02, CP04 and CP05 are responsible for all environmental activities specified in the contract between the contractor and the MRB.

ii. As conmmited, the contractors submit monthly progress reports enclosed with environmental sanitation and labour safety measures to PIC and MRB.

iii. During the construction, the construction contractors received the coordination, consultant and supervision of MRB, Project implementation consultant (PIC), Independent Environmental Supervision Consultant (Idom), environmental management agencies, and local community on the compliance with EMP.

155

34. Implementation of EMP of CP02, CP04, CP05:

i. The EMP was developed by the contractor VINACONEX, Hancorp and approved by MRB and ADB.

ii. The Contractor (Posco) of CP02 received approval from consultant developing EMP at construction site based on bidding documents (the 5th submitted version).

iii. During the construction, the Contractor strictly complied with the requirements on environmental protection (CP02).

iv. There is no complaint from local residents about the waste impact on the air environment, noise and vibration pollution. However, VINACONEX 2, HANCORP need to supplement more project informations on signal board at site entrance cause the old one is broken.

v. There have so far been no any accidents at the construction site CP02, CP04 and CP05. The health care Department for labourers at construction sites were setuped by Contractors CP05 and CP02.

35. The mitigation measures required in the EMP are being implemented by the Contractors during January to June, 20134. In general, no negative environmental issues drive during construction working. The average ratio of the measures effectiveness is between 1 and 3 (in accordance to ADB rating system), some criteria on solid waste management reaches hightest level (1) – very good. Posco collected, classified and transfered these wastes, embanked a site boundary, drill a cach-basin in order to ensure water and waste can not be aleaked to the environment.The overall evaluation of the mitigation compliance given by the Consultant would thus be good, ranking from 1 (very good) to 5 (very poor) as suggestion of ADB. Annex 4: Table of Mitigations Measures Required in EMP during January to June 2014 at Depot Site (CP04 and CP05) and the Viaduct Stations (CP02). Contractor should install mobilized lavatory for workers at site and it should be near the contruction area to keep sanitary.

4.2. OUTSTANDING ISSUES OF COMBINING ENVIRONMENTAL REQUIREMENTS INTO CONTRACT AGREEMENT WITH CONTRACTORS

36. The EMP developed in the bidding document will include the same information approved on the EIA. However, whether non significant diferences need to be carefully considered on the basis of higher environmental protection effectiveness, they must be approved by the ADB and the Hanoi People’s Committee when the MRB carried out their supervision. Apart from that, there are different comments from public media on cutting down ancience trees at Kim Ma street, these should be clear to residents in the last solution decision and through public consutation.

155

5. SUMMARY OF IMPLEMENTATION OF ENVIRONMENTAL IMPACT MITIGATION AND COMPENSATION MEASURES

5.1. COMPLIANCE INSPECTIONS 37. During the construction of CP02, CP04 and CP05, the contractors observe strictly the requirements on environmental protection and waste management during the construction, even in pre-constructio phase.

i. CP01: DEALIM have been signed the contract with MRB on 11/4/2014. During April to 6/2014, contractor of CP01 has implemented documents on management plan, as: Health, safety, environemt, quality control, security, interface, design schedule, construction management, material supply, design drawings, receiving ground at P345 to alternate this location with ring road No.2 and sign environmental service contract.

ii. CP02: Posco construction contractor has just signed contract with MRB on 14th August 2013. CP02 had fenced and drilled pile in a large scale at station No.1, No.2, No.3 and No.5 during January to June 2014.

Set up and maintain safety manager in contractor’s organization chart, 04 person at main contractor’s office is required.

Dust pollution control: Cover the transport vehicles with canvases when they are transporting aggregates such as sand and stones. Watering truck provided one time per dry day. 02 workers at stations have to stand by at site entrance to keep clean vehicles and ground. Sercurity guard has to check people and vehicles in – out of site erea and take note daily.

Water supply: For stations: Provided one unit of water truck to water working area per day; For workers: 20l bottles and plastic cups at site daily and make sure it must be clean and safe to environment.

Health and safety of workers and road users: Workers and engineers were provided safety helmet, boots, glasses, masks and appropriate clothing. There are annual training programs on security, environment and health to works and they’re requested to have this kind of certificate. Under approval of SYSTRA and Department of Transportation and Civil Works, the constractor installed signals, fences, trial fence, and flow distribution follow traffic safety plan, and implement control construction plan.

The place for filling soil construction wastes in a day work at construction stage of bored piles at a large scale, and dumping ground lisenced by Department of Construction.

Oily waste management: from heavy equipments and vehicles was collected and used for maintenance mechines. Moreover the contractors have their subcontractors to collect and treat wasteoil as hazardous if excessing after reused.

There were not any accident or incident concerning to fire or explosion at project area. Fire protection equipment and the accident processing as well as hot line of the person in charge were provided at site. These information should be available to public.

Implement GRM mechanism: Set up collection and complaint treatment system.

155

Provide hotline on signals at site and public areas. Project Director, Manager of HSE of POSCO take responsibilies on this matter (more information will be shown in EMP). 24/7 hours hotline and informations of MRB and POSCO are also shown on signal at site entrance. During 2 months of large scale construction, May and June, there have been no complaints from public. Details of the signal should be as follows:

Project Hanoi Pilot Urban Railway Line.

Constractor Posco co E & C

- Address: 1 Le Duc Tho, Cau Giay, Hanoi - Email:[email protected] - Hotline 24/7: Mr. D NG QU C H NG – Chief of Environment Department - 0983861970

iii. CP04 and CP05 at the Depot site:

Dust pollution control: During dry days, water twice or thrice at the surroundings of residential areas and entrance road to construction site.

Noise and vibration control: Noise and vibration level are lower than the allowable level in Vietnamese standards.

Water supply: Hancorp has been signed the contract with Hanoi Water supply for using fresh water for Depot area. The water pipe line connected from Nhon and highway No32 in Tu Liem district to Depot area.

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. Rain-water is collected into drainage system and follows into the lakes in project areas; it does not cause inundation to residential areas and neighbouring farming and outside fences at site areas.

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.

Sewage from the construction site CP04 and CP05 flows along the southern boundary, adjacent to the Road 70.

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). However, at CP04, contractor should supplement dustbin and collect waste around water tank.

Oil waste management: oil waste at the package CP04 and CP05 are mainly small quantities of oil leakage. The management of oil waste in the packages CP04 and CP05 were well performed as committed in the EIA Report 8/2013. Oil 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

155

Vietnamese provisions stated in the Circular 12/2011 on toxic waste management) or it could be used to reduce friction in spare part mechanics maintainance of heavy equipments.

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 when contractor begin with the new construction work for workers. In May 2014, contractor of CP05 has trained to workers on safe, environment and report data. However, workers of CP04 have not obeyed the regulations on labor safety at Depot site.

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 petrol stations which close to the project area. However, the contractor at CP04 uses casks as food drying bed is inadequate.

So far, there have been no fire and explosion accidents or incidents at the package CP04 and CP05.

38. Waste management at workers camps:

i. CP02: Using daily worker therefore doesn’t have worker stay at construction site.

ii. CP04: the workers camps:

There were no worker camps anymore now because Contractor has completed main contruction items on land clearance on 11/2013. Thus, access at site was closed. From 12/2013, site hut has not been a monitored item. From April 2014, the contractor removed this equipment and used it as accommodation to their staffs with a very little of number person. Labor workers were hired to work daily but in maximum 4 or 5 persons and they do not stay at site area.

The contractor’s temporaty site office is quite good.

iii. CP05 at the workers camps:

From January to June 2014, only daily workers are working at Depot site, 7 or 8 people a day. Contractor has no any worker camp ínide Depot and planned to hire a separate area for workers when they have highly intensive work. As their plan, the contractor will focus on the neighbor resident local area. Thus, this plan has been evaluating and assessing by MRB.

39. Overall evaluation of waste management measures in CP04 and CP05:

A number of mitigation measures have not been fully applied namely solid waste control and environmental sanitation control on the site and temporary office area. Contractors for both 2 packages need comply some more items as specified requirements in the EMP such as provide and install: signals on labor safety and sanitation regulations, particulary to dangerous activities: electric, working on height locations, weld…; mobilized public toilets, inform to worker to ensure that they can keep the labor safe regulations as well as protect by themselves and avoid risks at site areas.

40. Public transport management: CP02 (Viaduct stations) on the highway No.32 with heavy traffic, especially at the rush hours. During fencing station No.1, station No.2, station No.3 and station No.5 all activities were not affected to public transport, excepted the case at Terminal 5 in 1/2014 in. Due to the Lunar time so that when installing fence there, stagnant status jams appeared, and the contractor received instruction that they should postpone this activity and the contractor followed, they changed

155

their schedule to ensure delivery information in the Lunar New Year holidays. There are no complaints from local residents in surrounding areas.

41. Environmental consultant has monitoried the compliance the EMP at site. The check lists for civil works are shown in Annex 4 on Implementation Mitigations Measures Required in EMP during the months of January to June 2014 at Depot Site (CP04 and CP05) and Viaduct station (CP02). For additional data it can be checked on the Annex 4.

5.2. ENVIRONMENTAL MONITORING PROGRAMME 42. The Environmental monitoring program is included in the EIA 8/2013 cleared by ADB and the EMP as well Vietnam’s regulations at Depot site (CP04, CP05) and Station No.2 Viaduct station (CP02) with CENMA contractor.

i. Enviromental Monitoring Program is proposed in the Environmental Impact Assessment and Environmental Management Plan. CENMA is a unit directly under the Hanoi Department of Natural Resources and Environment as well contractor implement EMP of project. The environmental monitoring results were performed through monthly reports by CENMA including the following contents: Monitoring results of the analysis, 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.

ii. 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.

iii. CENMA and the construction contractors shall be responsible for complying with relevant regulations, and one of the monitoring tasks is to ensure the compliance with environmental regulations of the contractor.

iv. Periodical timeable of the contractor on Environmental monitoring: shown in Table 1, page 2 of this report. CENMA carried out 5 environmental monitoring times during last 6 months. The monitor could not be implemented in March due to bad weather, rained whole month.

43. The compliance with requirements on the measurement points as well as monitoring parameters in Depot and Viaduct station is defined in the Environmental Impact Assessment and Environmental Management Plan.

i. The Consultant CENMA is in charge of monitoring the on-going works of the metro Line concerning the environmental parameters, focusing on air quality, noise, vibration, underground water, wastewater and surface water, which may be affected by the construction activities under Environmental Monitoring Consultant Contract Ref. 05/2012/H -QTMT signed on 27th June 2012 and addendum Ref. 01/2012/PLHD/ HDTV-QTMT signed on 6/8/2012 for Package 3 belonging to the Project: "Support to integration of urban and environmental projects for the Hanoi pilot light metro line, section Nhon - Hanoi station" granted by AFD &FFEM, between MRB and CENMA. Thus, CENMA shall provide the environmental monitoring data collected, the corresponding analysis, as well as the monthly reports for the period of project implementation.

ii. Regarding Environmental Monitoring Consultant Contract Ref. 05/2012/HD-QTMT, the environmental monitoring program included two phases by CENMA, phase 1

155

includes 16 months from May 2012 to August 2013 which was done and phase 2 which is expected from September 2013 to February 2015. Phase 2 of the environmental monitoring program starts in September, 2013 without any change on parameters and frequency of Phase 1.

iii. Phase 2 of the environmental monitoring program has started in September, 2013 and expected will be finished in February 2015 without any change on parameters and frequency (monthly) of Phase 1.

5.2.1. Summary of monitoring results at the Depot site and Station No.2 at Viaduct station

44. 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.

45. Emission Monitoring Program is implemented by CENMA at 6 monitoring points including 2 point of air environment quality, noise level and vibration level, 1 point of surface water, 1 point underground water, and 2 point of wastewater with frequency 3 months /time (monitoring locations is shown in Annex 3 of this report) Monitoring Program shall be carried out by CENMA at Viaduct area.

46. In November 2013, CENMA starts monitoring at Station No.2 KXQ3A point (Viaduct station) in construction phase in accordance with standards, methods and frequency as cleared in EIA 8/2013. However, the parameters of surface water and groundwater have been adding more than EIA 8/2013 which approved by ADB required but they were required by regulations of Vietnam.

5.2.2. In-site on-going activities47. Summary of environmental quality monitoring results from January to June 2014: (the results and and their comparisions with QCVN current values of the results of monitoring specific parameters are presented in Appendix 3)

Depot and Viaduct site

i. Air quality:

At Depot area:

The monitoring point of KXQ1 is at NorthEast side of Depot, KXQ2 is at West side of Depot, at the main entrance and very near from Road 70 and far 120m from the lake insite Depot). In general, at KXQ1 has good air quality, all of parameters monitoring are lower than the allowable limits in the National Regulation (QCVN 05:2013 - National technical regulation on ambient air quality). At KXQ2 has total suspended particulates (TSP) exceed the allowable limits in the Vietnamese standard (QCVN-NTR) from 1,5 to 1.7 times, SO2 exceed the allowable limits but not significant, much more 1.01-1.2 times, and benzene concentrations were slightly higher than the standard limits at 1.07-1.2 times.

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).

At Viaduct station area:

The monitoring points located on the main road with hight traffic flow. The first time

155

monitoring in construction stage was in 5/2014 which was at right after the Contractor had their commencement and the result shown that air quality at KXQ3A has TPS, SO2, and Benzene parameters overcome limits. Dust concentrations are higher than allowable limits in QCVN 05:2013 from 1,4 to 1,47 times, SO2 exceed the allowable limits but not significant from 1,01 to 1,1 times, and benzene concentrations are higher than the allowable limits 1,2 times 22,25 μg/m3 (in Jan2014) – 26,53μg/m3 (in May2014) while the permitted highest concentration in QCVN06:2009 is 22 μg/m3. It’s a big problem but there is mixed between different pollution sources, not only from project.

In summary, air quality during six months including January to June 2014 showed that no pollution at the monitoring point of KXQ1, but KXQ2 and KXQ3A had TPS, SO2, and benzene concentrations higher national limited standards, at and KXQ3A had. The reason must be due to direct impacts from the exhausting of vehicles which are being in transportation activity on the main public road, the Road 70, 32. They are the big road in front of Depot gate and along to CP02 site. Some kind of pollution concentrations air at Depot areas has the trends in this period as below: SO2 had signs of increasing but in May it decreased just a very little; TPS and PM10 are slightly lower because of water spraying, however it was still at the levels could cause pollution.

ii. Noise level:

Noise monitoring points are also at the same monitoring points of KXQ1 and KXQ2 at Depot area and KXQ3A at S2 viaduct station. At these 3 points, Leq parameter from 6am to 9pm ranges slightly higher than the allowable limits (70 dBA) but at night time, it ranges lower than 57dB at KXQ1, higher than 63dB at KXQ2 and KXQ3A while night standard level is 55dB in QCVN 05:2010. In general, noise pollution alongs main road is localized and its Leq values decreases along distance of noise source. That’s the reason to not consider that this pollution source was from the contruction site of the project. To identify the scope of noise impacts from the project site exactly, we can use the method monitoring at each noise source to canculate.

iii. Vibration:

Depot area: Vibration acceleration measured at KXQ1 and KXQ2 from January to June 2014 day and night value varies lower than the allowable limit 46dB in the National Regulations of Vietnam (75 dB). It

iv. Surface water:

The monitoring results of surface water (lake) in Depot from January to June 2014 show that the surface water of this lake is satisfying the national standards.

v. Ground water:

The monitoring results of groundwater during six months show that all parameters of the groundwater were under permission levels.

vi. Wastewater:

Waste water quality is monitoring one time every three months at NT1 and NT2. The monitored results showed that waste water quality at NT1 inside Depot satisfied NTS but the waste water at NT2 was pollutted by Coliform. It has coliform concentration exceed 1.2 to 2 times the allowable limits (QCVN 14:2008). The reason is this point receiving too many sources from resident area. Other parameters all below the allowable limits of the QCVN 14:2008.

155

5.2.3. Evaluation 48. 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 about the sources in fact. In addition, the emission level can be compared with real basic conditions (if the database is available) and described about the quality or evaluated on the base of ranking system as follows. The statistical monitoring data can be found at Annex 3.

51. The selection of the parameters of chlorinated organic plant protection chemicals to monitor the surface water of the package CP04 and CP05 is not necessary.

52. Comparison Standards (QCVN):

i. Environmental monitoring activities are performed by CENMA in compliance with the current standards and regulations of Vietnam (regulations on receiving, preservation,

155

transportation, sample analysis).

ii. Comparison Standards on are based on the current Standard of Vietnamese

iii. Several monitoring parameters is not currently prescribed in the Vietnamese Code, therefore; the monitoring results are only informative, namely: Dust concentration parameter PM10 and PM 2.5, Pb dust at hourly average.

iv. 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), Ammonium, 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.

v. These parameters are selected to monitor the construction package performance because they are appropriate to the environmental standards issued in Vietnam.

5.3. MONITORING AND INSPECTION PLAN 53. Activities proposed to be implemented during the next 6 months:

i. Periodic monitoring at works site of CP01 (pre construction site), CP02, CP04 and CP05 (contruction stage): 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 construction contractors by Consultants.

ii. 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.

iii. Coordinating with CENMA to assess the quality of the surrounding environment to evaluate the impacts of the project activities.

iv. To monitor the package CP01, CP02 and CP03 those shall be constructed in coming time at construction phase and pre-construction phase regarding to EIA 8/2013 of ADB.

155

6. OUTSTANDING ENVIRONMENTAL ISSUES AT THE METRO LINE 3

6.1. THE EXISTING ENVIRONMENT PROBLEMS ARE DETERMINED 54. 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. During high-intensity work, sometimes vehicles generates dust to influence on the health of workers.

ii. Noise measurement in the construction site had some measurement times slightly higher than the standard, mainly in night time, from 9pm to 6am. The main reason of this kind of pollution is the public traffic and there are many varies noise sources, as: noise during construction, movements of mobilized batching plants, bentonit, pilling hammer, etc. but the transportantion activity on the road is the most important line source as its continuity. To reduce those kind of noises: construction equipments and vehicles should be maintained in good condition, minimum vibrate horn, use of silencer equipment in cenders, install acoustic barrier and fences, to avoid professional deafness, workers should use noise-protective capsules and plugs.

iii. Waste water: Coliform concentration at NT2 exceeded standard at some measurement times,. However, at this ennvironment monitoring point, the wastewater receiving from both the site and the residential areas while all parameters presented for the wastewater at NT1 were under NTS so that we can confirm this impact was not caused by this project. According to the requirements as well as the contractor's commitments in the environmental management plan, the contractors CP04, CP05 need to provide more mobile toilets with sanitation standards on site for workers during construction stage and use yeast microbiology for septic tanks to handle within the site.

iv. Currently, the CP05 is planning not to install worker camps at site but in resident community so they need pay attention on the strict sanitation rules/regulations and implementing it to minimize the conflict between indigenous people and workers.

v. CP02 (Viaduct stations) on the highway No.32 with heavy traffic, specially at rush hours. During fencing of station No.1, station No,2 and station No.3, all activities did not affect to public transport. Posco has well implemented articles in Enviromental Management Plan, timely adjustments in their activities, for example in the case of Terminal No.5 by installingn and dismantling the fence in 1/2014 because of Tet holidays. CP02 is entirely possible place for learning, sharing between contractors if the project advocates to hold periodically safety and environment patrols to check safety and environment conditions for the whole project as a multi-stakeholder plan.

1

Air pollution on site

Transport impacts of the Road 70 close to the project and vehicles transferred materials (e.g., soil, cement, stone, sand, aggregates, etc.).

Keep stockpiles moist and cover vehicles with tarpaulin sheets or other suitable materials to minimize dust emission and prevent spillage of materials (e.g., soil, cement, stone, sand, aggregates, etc.). Maintained equipment regularly especially exhausts.

Contractors Every day during construction phase

Not regularly because have not too many activities on the whole site but this works pretty seriously at the station was constructed package CP02 since the end of May. The number of workers at Depot were always under 10 persons

2

Noise level at some measurement times are slightly higher than standard at Depot site and Viaduct area.

The vehicles and machinery that makes noise and vibration during the construction as well the traffic congestion on the road

The speed limit for vehicles and machinery during the operation in the project (<10km/h) Change the pile hammering technique to soft pile sliding. Use silencer for heavy equipments and maintain in good conditions.

Contractors and traffic congestion on the road

Every day during construction phase

regulation for Vehicle speed, operating machines within the project area does not exceed 10 km / h as EMP However, due to the traffic noise in Hanoi today always exceeding always on and arround the main traffic routes so it’s certainly that the worth monitoring measurement at the on-site points

Avoid benefit conflict between workers and local residents if any

CP05 propose that will rent the camp worker area of local residential houses, it is inside local community

CP05 should develop a worker camp management Plan before renting a worker camps

Contractors Local authorities MRB

In July 2014 CP05 should develop a worker camp management Plan before renting a worker camps Worker camp management plan should be approved by MRB with agreement of local authority

7. GRIEVANCES

7.1. DETAILS ON GRIEVANCE/DETAILED REGULATIONS ON GRIEVANCE FROM LOCAL RESIDENTS AND RELEVANT PARTIES ON ENVIRONMENTAL IMPACTS

56. MRB has so far not received any grievance (oral or written) from local residents and/or relevant parties on environmental issues of the implemented packages CP02, CP04 and CP05.

7.2. SOLUTIONS TO DEAL WITH GRIEVANCE LETTERS SETTLED OR TO BE SETTLED WITH INFORMATION

57. Currently MRB and contractors are carrying out GRM at project level with main contents as follows: when installation of stations or new items, information of person incharge should be added (supplemented for the old stations, if any). When construction starts, contractors organize reception division to record claims at site areas, security gate. Claims (if any) of the public shall be reported to main office by contractor then to MRB by the office within 24 hours. Contractor publicizes name and telephone number (including hotline) 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 with compensation, claim mechanisms in legal system described in Environmental Impact Assessment Report.

8. CONCLUSIONS AND RECOMMENDATIONS

8.1. OVERALL PROGRESS OF IMPLEMENTATION OF ENVIRONMENTAL MANAGEMENT MEASURES

58. The packages CP01, CP02, CP03, CP04 and CP05 have included EMP into the bidding document. The EPM is prepared by Contractors and supported by Systra.

i. Package CP04 has completed all the main construction works in the expropriated area and CP04 complied with environmental impact mitigation measurements. At present, they just do remainance and repair some smail mistakes of the construction work which they finished with a few number workers

ii. The Contractor (HANCORP) in charge of package CP05 submitted the EMP to MRB on April 2013 and Contract Addendum No 12/2012/PLHD-TCXD signed on 30th October 2013. The contents on EMP have been approved but they not start their work with the reason mentioned above.

iii. The Contractor (Posco) of CP02 has started in September 2013; the construction works at site fenced at station No1, No2, No3 and No.5, the main construction works have been implemented since the end of May 2014.

59. In general, the compliance mitigation measurement at the Depot site (only CP04 and CP05) and viaduct site (CP02) have complied by contractors as EMP’s requirements. The compliance with environmental requirements of project is satisfying level based on the real schedule of CP04 and CP05 were just a few activities, the distance between Depot and resident area enough . It is considered that conditions on the depot site (CP04 and CP05) are much easier to handle in terms of environment and safety than what is anticipated on the construction sites of other packages along the metro Line 3. So, for the environmental and safety management of CP01, 02 and CP03 the difficulties to be faced later on (which will definitely be a higher) must be thoroughly estimated

60. MRB has so far received no complaints (in either oral or written forms) on environmental issues.

61. 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) and Station 2 at the Viaduct station. CENMA sent to MRB all monthly reports on the quality monitoring results of the environment to MRB. However, CENMA contractor need update the changing of monitored ambient air quality parameter from NOx to NO2 as prescribed by QCVN 05: 2013 (revised parameters).

62. There have been no environmental incidents or environmental complaints during January to June 2014 at the Depot and Viaduct station construction site.

155

8.2. IDENTIFICATION OF PROBLEMS AND SOLUTIONS

8.2.1. Conclusion 63. Air pollution at KXQ2 (the gate of the Project area – near Road No.70) and KXQ3A: Solution: Increasing water spraying to reduce dust regularly and constantly.

64. Lacking mobile toalets: install immediately mobile toiles and building a temporary car washing station should be finished before September 2014.

65. Avoid benefit conflict between workers and local residents, CP05 should develop a worker camp management plan before sign a renting contract for worker camps outside Depot. This worker camps management plan should be prepared carefully and getting support from local authority beside and MRB’s approval before implementing.

66. Posco is the best contractor in implementation EMP. They themselves have periodical internal audit, standardisation documents on health-safety-enviroment for workers, suppervisor group can handle offence under the principle regulations, agreements between main and every sub-contractors as well as having a good frame of sanctions to follow at site. They also build small ciment embankment as foot leg of fence, store tank, solid pavement at staions to prevent waste spread to public areas and in order to keep good repubtation for themselves (More detail at annexes).

8.2.2. Recommendations 67. The compliance with EMP should be weekly or monthly monitored by environmental specialist. MRB should continue to request the Contractor to take effective measures strictly in order to carry out the environmental supervising plan as supported by the PIC (SYSTRA).

68. MRB should request the contractors to follow both of ADB regulations and curent Vietnamese Environment Law and regulations to ensure their compliance and minimize adverse impacts on the environment.

69. CENMA – the environmental monitoring contractor need to re-select the monitored parameter is NO2 rather than NOx to meet right with the latest regulation version QCVN 05:2013 and in accordance with international regulation.

70. 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. A worker himself is the first person who takes the primarily consequence of his non-compliance action..

71. Currently, the CP05 is planning not to install worker camps at site but in resident community so should be pay attention as well strickt rules and sanctions to minimize the conflict between indigenous people and workers, it should be approved by MRB and local authority before seting it up.

72. Providing more recycle bins and mobile toiles at Depot area on the site to prevent making mess which can cause pollution. The waste management .

73. Enhancing the safety environment training course, especially for Vietnamese contractors in order to affort them implement their corporate social responsibility better in environmental management and protection issues.

74. It is necessary to enhance the capability of MRB staff and relevant parties who are involved in the supervising and monitoring on site, and the solutions to gain this goal should be practical, simple and

155

effective. At first, to improve effectiveness of implementation of project’s safe and environment plan, it need to alternative safe inspection (safety patrol) in which including environment aspect between constractors’s HSE groups, with attendance of Consultant. Poscomodel is recommended to use as a sample.
