I. EXECUTIVE SUMMARY 1. The Basic Infrastructure for Inclusive Growth in Northeast Provinces sector project (BIIG 1) will invest in the recently completed Four Northeastern Provinces (FNEP) Overall Development Plan (2015). The development plan responds to the Government of Vietnam's strategy of targeting the investment into poorer provinces and regions. The use of a sub-regional approach seeks to build the interrelationship between provinces as one of the foundations for accelerating growth in the more remote regions. As such, the plan targets investment into outputs that build areas of comparative advantage in a manner that increases the competitiveness of economic activity in the sub-region. The expected impacts of the project are to improve socio-economic wellbeing of local communities through the improved financial returns and through lower costs of accessing public health services, education, water supply and markets. 2. The project has four outputs being (i) improved road network connectivity with the Four Northeastern Provinces (FNEP), (ii) improved rural water supply, (iii) upgraded agricultural rural value chains (ARVCs) in Lang Son and (iv) decentralized public asset management processes. A. Subproject description

B. Subproject screening and categorization

8. During the PPTA works for the BIIG 1 Project, an Environmental Assessment and Review Framework (EARF) was prepared in April 2017 to guide screening and selection of roads, environmental assessments and to monitor implementation of environment safeguards during project implementation. EARF complies with ADB Safeguards Policy Statement 2009 (SPS 2009) as well as the national laws and regulations with respect to environmental management and conservation. 9. As per the project classification on environment aspects the subproject “Construction and Expansion of Domestic Water Supply System in Coc Pai Township and Adjacent Communes of Nam Dan, Ban Ngo, Xin Man District, Ha Giang Province” falls within the scope of category B (please refer Rapid Environmental Assessment (REA) checklist attached in appendix 8 of this report). Thus, Initial Environment Examinations should be carried out for this subproject in accordance with the SPS 2009.

10. The information about the environmental status in this IEE report is collected from Ha Giang Department of Natural Resources and Environment, Xin Man District Natural Resource Division, and from other published documents. The IEE is prepared in the feasible design phase to identify and evaluate impacts, and propose mitigation measures for three phases: preparation, construction and operation. In addition, the IEE includes necessary mechanisms to ensure the EMP implementation. 11. The subproject can cause negative impacts on natural environmental, ecological resources and cultural tangibles. Most common impacts occurring during the construction process are dust, noise, traffic interruption, waste generation. These impacts can be mitigated by standard mitigation measures. 12. During the preparation phase, potential issues that have been identified are (i) land acquisition and resettlement. The subproject affects two H'Mong ethnic minority households in Nam Chanh hamlet, Nam Dan commune and and one household of H’Mong ethnic group in Coc Pai town, Xin Man district, Ha Giang province. They are affected with approximately 5.500 m2 (2,000m2 of perennial land and 3,500m2 of annual crop land) (ii) impacts on flora and fauna, (iii) Demining mines and explosives (UXO) and (iv) removal and slope terrain. To minimize these impacts, (i) A resettlement and ethnic minority development plan (REMDP) has been prepared and approved by ADB in September, 2019. The REMDP will be updated and confirmed. Appropriate compensation and support shall be arranged for affected households before construction starts. Ha Giang PMU under Ha Giang Department of Planning and Investment will review the land acquisition and resettlement procedure before the construction to ensure that all affected households receive full compensation according to the policy of the Vietnamese Government and the ADB; (ii) Trees cultivated by local residents will be removed and compensated under the provisions of the REMDP; (iii) Ensure the stability of slopes to meet the gravity demand of the raw-water pipeline from upstream; (iv) Coordinate with a specialized military unit to survey and clear bombs, mines and explosives (UXO). 13. During the construction phase, the environmental issues to be identified are: (i) Construction wastes include construction solid wastes, domestic solid waste and hazardous waste; (ii) Gaseous emissions generated by the construction activities; (iii) Generation of dust from construction activities; (iv-v) Noise, vibaration from construction activities; (vi) Local Traffic; (vii) Safety risks of construction workers; (viii) Impacts on local community’s safety and business; (ix) Degradation of surface water quality; (x) Impacts by the influx of construction workers and (xi) Impacts on local community’s safety and business .To mitigate these impacts, the mitigation measures shall be taken, the detail about mitigation measures in the table 15 of this report. 12. During the operation phase, the negative impacts to incurr are (i) degradation of water quality from upstream weir on Thac Tien waterfall and inappropriate maintenance plan; (ii) Accident risks during the operation of the plant (iii) Fire incident and electric breakdown at the substation. To reduce impacts, it is neccessary to (i) monitor water quality under the regulations of QCVN08:2015/ BTNMT; (ii) provide measuring equipment to control the amount of chemicals used, check the quality of treated water each month, evaluate the chemical residues in the water; and (iii) Xin Man district Power Company will be responsible for operating and maintaing the substation.

14. According to the Vietnamese Law, for a water supply facility with a capacity of less than 50,000m3/day, it is not necessary to prepare an Environmental Impact Assessment Report (EIA) including public consultation but in accordance with the ADB Safeguard Policy Statement, for category B subprojects, it is essential to conduct public consultation. As such, the consultation on WTP construction, technology processes, alternatives on water supply, etc. is important during actual survey in the subproject preparation. Public information and consultation activities were carried out as part of a baseline survey of local environmental conditions along the subproject sites. The meetings with local authorities and public communities took place in Nam Dan, Ban Ngo CPC and Coc Pai Town PC during 3 days from 7 to 9 December 2017. 15. During the consultation on environmental issues, local authorities and people of some households were given an introduction to the subproject, anticipated environmental impacts and mitigation measurements, the subproject implementation schedule and relevant environmental issues. Overall, there was no opposition raised with respect to the proposed subproject. 16. Four-steps grievance redress mechanism will be established for the subproject, social as well as environmental safeguards to handle environmental impacts and land occupation. As a guideline, any complaints to subproject activities will be solved through negotiation to get agreement. Complaints will be submitted toward three institutional levels: Firstly, through commune/ward’s PC, then the town’s PC and finally through PPC. If an agreement was not reached, they will be sent to Law court as the final method. The Center of Water Supply and Drainage in Xin Man district will be responsible for the administrative costs of dispute resolution procedures during the operation phase. E. Institutional implementation arrangement

17. The Ha Giang BIIG 1 Project Management Unit ( Ha Giang PMU) has been established by Ha Giang Department of Planning and Investment to undertake the subproject activities at all phases. One PMU officer has been appointed as Environmental Safeguard Officer (ESO). An Environmental Safeguard Specialist (ESS) of the Loan Implementation Consultant (LIC) will organize a formal training course about the roles and responsibilities of EMP implementation and training at site for staff of PMU, CSC, community, Contractors and support the establishment and operation of the subproject environmental management system during the construction phase. The ESS will also support the capacity building for the PMU by reviewing and evaluating the environmental protection capacity of the PMU and Ha Giang Department of Planning and Investment during the operational phase. 18. In order to ensure that environmental protection and mitigation measures are provided in civil work contracts, EMP will be included in the bidding documents and the civil work contracts. Any deficiency of environmental management costs will pose a high risk for the implementation of the mitigation measures during the construction phase due to the lack of resources and capacity, thus, funding and responsibility for environmental protection must be provided at first. It is also required for Contractors' to offer qualified and trained staff on environmental management and safeguards in the bidding documents so that the mitigation measures would be effectively monitored during the subproject implementation. F. Conclusion and Recommendation

19. The IEE concludes that the feasibility study of the subproject combined with available information is sufficient to identify the scope of potential environmental impacts and formulate

IV. DESCRIPTION OF THE SUBPROJECT

A. The necessity of the subproject

33. The Coc Pai Township has significant difficulity in accessing hygiene domestic water source. The Town currently has a self-flowing water supply system through DN75 galvanized steel pipes. The water source is taken from watershed area to preliminary treatment plant, then the water is distributed to the town by galvanized steel pipes DN15-DN75, the capacity reaches at 780m3/day and meets about 45% daily needs of households. Especially, the rapid reduction of water resource is caused by deforestation for cultivation; meanwhile, the pollution of water source comes from unintentional behavior of people in water resource protection, usage of chemical pesticides and waste discharge of human and animals. In general, the current situation of water use is not enough (both in quantity and quality of clean water source). The adjacent communes such as Ban Ngo and Nam Dan do not have clean water works; however, some invested water pipes are only being capable of serving a part of households near water source area. Addtionally, water resources are mainly from small water ravine that is unhygienic and do not meet the quantity requirement. 34. The current water supply system in Xin Man District has significantly affected the daily life and production activities of people in Coc Pai Township and adjacent communes as Nam Dan and Ban Ngo, Xin Man District. Therefore, it is necessary to focus on investing the domestic water supply system in Coc Pai Township and adjacent communes of Nam Dan and Ban Ngo, Xin Man district, Ha Giang province. The construction investment is in accordance with the general social development within the National Rural Clean Water Supply and Sanitation Strategy to improve the quality of life, shorten the gap of economic life between the mountain and delta. 35. The feasibility study confirms that after completion, the subproject will supply a secure 24- hour water supply service to approximately 6,710 beneficiaries based on the projected population and demand forecasts for 2030. The system can support an expected population growth rate from 2 to 2.2%/year in 10 years (increase to 9,968 people). 36. Location of the clean water supply station in Nam Dan commute and Water Tower in Coc Pai Township and the general layout of the proposed Water Treatment Plant (WTP) are shown respectively in the figure 1 and figure 2 below.

V. DESCRIPTION OF THE ENVIRONMENT A. Natural conditions

52. The Ha Giang province has a complex topography with large altitude variation. The average elevation of Ha Giang is at a range of 800m - 1200m above sea level (MASL) with 5 mountains have the height varied from 2,000m to 2,500m. In general, Ha Giang topography could be divided into three main areas - they are: 53. Area I: the high Stone Mountain in the North called as Dong Van Karst Plateau is lying on the administrative areas of four districts (Quan Ba, Yen Minh, Dong Van, Meo Van). 90% of the natural area is Karst Mountain, typical for karst topography. Dong Van Karst Plateau has become a member of Global Geological Park network in 03 October 2010. 54. Area II: The high area in the West including as 3 districts of Hoang Su Phi, Xin Man and Quang Binh. This is the subproject area and part of Bac Ha plateau, called as Chay River stilted arch with the average elevation from 1,000m to 2,000m. The mother rock in this area is mainly granite with feralit topsoil, from red to light yellow, grey yellow and some parts of humus allitic soil in the mountain. 55. Area III: The low soil mountains including the administrative area of Bac Me, Vi Xuyen, Bac Quang districts and Ha Giang city. The mother rock in this area is mainly metamorphic rock with topsoil that varies from red to light yellow, grey yellow; and the thickness of the layer is varied from 0.8 to 2m. The dominant topography of the area is low slope mountain and create large cultivation area above 50ha. This are is also has some dense forest strip in the flat and narrow valley along rivers and streams.2 56. The subproject area includes Coc Pai Township, Nam Dan and Ban Ngo commune, Xin Man district. The location is described as follows: The Coc Pai Township has the following administrative boundaries as: - The North is adjacent to Chi Ca commune, Then Phang commune.

1. Weather, natural disaster and climate change

59. The Ha Giang province usually received deflect cold movement from the plain area and the Northeast mountainous area so there is no extreme cold condition period like in the Northeast mountainous area. Only in some high area, near the peak of the mountain like in Pho Bang area - 1,400m MASL, where the lowest temperature could fall down to 5.60C. The topographical conditions of Ha Giang - Viet Bac mountainous area and Hoang Lien Son Range where Ha Giang province is lying on has support the Province a high humidity conditions. The average humidity is usually high at 80 to 87%. 60. The annual rainfall is different between regions from 1,031mm in Thuong Phung commune, Meo Vac district to 4,721mm in the subproject district of Bac Quang and 4,846mm in Quang Ngan commune, Vi Xuyen district. The largest rainfall center of the Country has been formed in two districts of the subproject as Bac Quang and Vi Xuyen that reached at approximately 4,700 to 4,800mm. The rainy season lasts for 6 to 7 months, from April to October with the rainfall makes up 83-91% of the total annual rainfall. December and January are the driest months of the year with the rainfall only at 25mm. The rainfall amount in Xin Man district stays below 1,500 mm belonging to the low rainfall regime. 61. The climate condition in Ha Giang province is diversified not only based on the elevation but also the direction of mountain range. Ha Giang is not usually suffered from tropical storm but thunderstorm, hailing and frost fog happened frequently. The "thunderstorm" day could be reached up to 90 - 100 days per year. 3

2. Hydrology

62. The Ha Giang province is situated upstream of 3 river basins including Lo River, Gam River and Chay River. The Chay River comes from Tay Con Linh range and flows Northeast -

3 Status of Environment report (SOE) of Ha Giang province 2015 prepared by Environment Analysing and Technique Joint Stock Company under the Assignment of Ha Giang DONRE in July 2015. SOE has analyzed hydrological data of 35-50 years from 5 hydrological stations and 32 rainfall stations in Ha Giang province.

3. Seismicity

65. Vietnam has been classified as a low seismicity region although the earthquakes up to degree VI on the Modified Mercali Scale have occurred several times in the Northern mountain region including Ha Giang province.6 Ninety percent of the earthquakes occurred in Vietnam have taken place in the Northwestern provinces. Since Ha Giang lies along the Lai Chau - Dien Bien Fault, the earthquakes could happen mostly at low intensity (under degree IV) and the earthquakes center usually along the fault next to Thanh Thuy Border Gate in Thanh Thuy commune, Vi Xuyen district. To demonstrate, at 12h45 on 17 July 2005, a magnitude 4.5-richter scale earthquake occurred in Lung Cu area, Dong Van district causing minor damage but no fatalities.7 Before that, a small earthquake with the magnitude of 4.7-richter scale was recorded at 8h54 on 13 May 2011 in the area of Piabioc Mountain, 50km from Ha Giang city.8 B. Ecological environment

Meanwhile, Ban Ngo commune has the highest poverty rate with 472 households (65.9%) and Nam Dan commune reaches at 480 households (63.4%). 2. Economic development and income 76. This is a shifting direction that the province, district, commune authorities are focused on as well as local residents is actively involved in creating jobs and increasing more sustainable income. Besides, in the Coc Pai Township, there are four convenient residential groups in terms of transportation, trade and infrastructure investment, thus it is appropriate to focus upon the development of business services. During 2016, goods trading and exchange services in the township get over VND 250 billion. The total number of tourists is reached up to tens of thousands. The Nam Dan commune is also striving to become the village of ethnic handicraft embroidery. 3. Social services 77. Health facilities including quality clinic facilities, doctors and nurses are available to provide health care services at communal level. Every commune has a clinic located in the commune center with one doctor and three nurses/midwives. In the Coc Pai Township, there is a district hospital. During the field trips, participants in the discussion group are stated that they are satisfied with the health care services; whilst, more and more babies are currently delivered in the communal clinics. 4. Historical, cultural and religious presence 78. In the Nam Dan commune, national monuments have been recognized such as the

5. Unexploded ordnance 82. There has been no armed conflict in the site in recent decades. Nonetheless, 40 years after the Sino-Vietnamese war, UXO remaining from aircraft, booby traps and land mines are indiscriminate and all of which is still concealed; meanwhile the information on the extent and location of UXO is sparse. In some locations, such as the sites of former combat bases or military

83. The water source of the proposed water supply system is the Suoi Tien waterfall, which is located within Nam Dan commune, near the provincial road from Yen Binh to Coc Pai Township. It is about 22km from the town center. The waterfall is situated at approximately 1,200m above

85. The result of water analysis at the Suoi Tien waterfall during two periods has shown that: Table 8. Test result of physical and chemical analysis on raw water source

The test results of water quality in Suoi Tien waterfall was relatively good; all parameters are within the allowable limits of column A2 QCVN 08-MT: 2015/BTNMT (National Technical Regulation on Surface water quality) 87. The subproject operation and maintanance plan would include a regular water testing program to detect any changes in the ambient quality of the water source and confirm that the water in the clean water tank distributed through the pipeline network meets national treated water

9 The Design Consultants strongly recommend that monthly water quality tests should be undertaken once the water supply system comes into operation.

Groundwater quality 88. According to the Environmental Status Report of Ha Giang province for the period 2011- 2015, the groundwater quality in the project area is relatively clean. In the project area, there have yet any findings related to groundwater pollution. Ambient Air quality 89. According to the observation results of ambient air quality in 2019 of the Ha Giang Department of Natural Resources and Environment, it indicates that the concentration of TSP, NO2, SO2 and CO is lower than the permissible limits of the QCVN 05:2013-BTNMT: National technical regulation on ambient air quality at the monitoring point KK-XM01- the center of Xin Man district, the first column Km 00- Coc Pai Township. 90. The average value of noise in the daytime is about 70 dBA which is under the permissible limit of the QCVN 26:2013: National technical regulation on noise; Soil quality 91. The degradation of the soil environment quality is often related to intensive farming practices using inorganic fertilizers, mining activities, construction materials or industrial activities. Nevertheless, these activities currently are not available in the project area but mainly small-scale farming activities on the household scales. Therefore, in the project area, there have been yet any findings related to soil pollution in the Environmental Status Report of Ha Giang province for the period of 2011-2015.

VI. IMPACT, ALTERNATIVE AND MITIGATION MEASURES

Environmental Less landslides during the Easily happen landslides due to steep aspect construction phase terrain On the basis of technical, environmental and social aspect, the Project have The selected option chosen the option A at Km45+500 (Yen Binh to Coc Pai) near the area of Nam Dan commune.

96. The subproject scope aims to meet the investment objective of sufficient water for domestic use for the 6,710 local people and employees in Government agencies, schoolds, medical aid stations during the dry season. Moreover, the demand requirement forecast for 10- year later (2030), with the growth level from 2 to 2.2, the total population will reach at 9,968 people. The estimated scope of the subproject is: 1- Installation of a distribution pipeline network of total length L = 41,682m. 2- The water treatment plant with the area of 2.000m2 and the capacity of 2,600m3/day (consisting of the operational office; chemical pumping house, pumping station; mixing tank with clarifier and filter; one water tank with the capacity 500m3 and the auxaliry works). 3- Construction of a clean potable water tank with the capacity of 500m3 on a high hill towards the West of Coc Pai Township. 4- Metered-household connection 97. The Suoi Tien waterfall is located within the Nam Dan district, near the provincial road from Yen Binh to Coc Pai and about 22km from the town center. The waterfall is at approximately 1,200m above sea level. Water flow ranges from 1.36 m3/s to 4.52 m3/s that are capable of supplying domestic water source to the town and adjacent communes. Furthermore, the water has low turbidity which is able to be treated for domestic water supply. At present, the feasibility study report only proposes the plan to get raw water from the Suoi Tien waterfall. D. Potential impacts/issues and mitigation measures in pre-construction phase

1. Impacts from land acquisition and resettlement 98. Impact on land: The subproject affects two H'Mong ethnic minority households in Nam Chanh hamlet, Nam Dan commune and and one household of H’Mong ethnic group in Coc Pai town, Xin Man district, Ha Giang province. They are affected with approximately 5.500 m2

Commune/ Total area Perennial land Annual crop No Town affected (m2) (m2) land (m2)

1 Nam Dan 5.000 2.000 3.000 2 Coc Pai 500 500 Total 5.500 2.000 3.500

Source: IOL results, September 2017 100. Impacts on houses and architecture: no impact. 101. Impacts on trees and crops: In the Nam Dan commune affected about 2,000 m2 of tea, 3,000m2 of cassava of 2 AHs. Coc Pai town is affected by 500m2 of upland rice of 1 AHs. 102. Mitigation measures: A resettlement and ethnic minority development plan (REMDP) has been prepared by PMU to address the issues on compensation and resettlement under the SPS statement and approved in the middle of October, 2019 by ADB. The PMU will inform the authority of Xin Man township and local people all information about the construction before starting. The compensation payment process must be monitored to keep records and resolve complaints. 2. Impacts on flora and fauna 103. Impacts: The construction work will involve the removal of trees along the route to the WTP and water tower. Trees grow on the edge of the road, mainly small trees, upland rice, and some of industrial crops. These plants are mainly crops which do not represent for any particular habitat environment. The number of trees cut down will be small so the impact on subproject ecosystem is insignificant. 104. Mitigation measures:Trees cultivated by local residents will be removed and compensated under the provisions of the REMDP. To reduce the impact on further trees and vegetation, the DARD office of Xin Man district should be informed about the number of trees cut down, construction time and progress. No fuel wood is allowed to utilize for construction activities or cooking and heating in worker camps. Besides, the contractor should take control measures to prevent workers from collecting timber, firewood from the surrounding forest or trading wood and fuel wood from illegal sources. The PMU assisted by the ESS and CSC will strictly supervise and monitor the protection of trees and other vegetation. 3. UXO removal 105. Impact: To ensure safety during project construction, it is necessary to identify the risk of unexploded ordnances. It is necessary to consult local people about mine-related accidents at

1. Construction waste 109. Solid waste generated during the construction includes three main types as follows: (i) Construction solid waste (debris); (ii) Domestic solid waste; (iii) Hazardous solid waste. Specifically, construction solid waste is mainly debris from unsuitable materials from installation of transmission pipeline, packaging materials, pieces of iron and steel, etc in the construction site. (i). Construction solid waste 110. Impacts: Construction solid waste generated from ecavation of water treatment plan (WTP), clean potable water tank and installing of transmission pipeline and estimated is approximately 14,961 m3. Construction solid waste will be transported to the disposal site at km 45+700 (in right of the route of PR. No. 178) at Nam Chanh hamlet, Nam Dan commute, Xin Man town according to the agreement among Ha Giang BIGII PMU and local authority of Xin Man Town and Nam Dan commute. The transport route of construction solid waste is along PR.No.78. The route has almost no resident living round. The level of impact assessed as minor can be mitigated during construction. 111. Mitigation measures: The separated construction waste can be reused or recycled before being transported to the disposal site at km 45+700 (in right of the route of PR. No. 178) at Nam Chanh hamlet, Nam Dan commute, Xin Man town. The reuse of weathered soil, wood, bricks for the purposes of backfilling, and taking advantage of wood debris for heating, cooking, etc could be conducted. Meanwhile, steel, iron, packing material and other materials could be recyclable to purchasing companies. 112. Construction solid waste will be stored temporarily at construction site before moving to disposal site. Contractors must ensure the following: i) Keep a safe distance of 250 m from water source of stream at Ban Ngo bridge and existing Dam of Suoi Tien waterfall; ii) keep a safe

Basic Infrastructure for Inclusive Growth in the Northeast Provinces Sector Project Initial Environmental Examination (IEE) of Construction and Expansion of Domestic Water Supply System in Coc Pai Township and Adjacent Communes of Nam Dan, Ban Ngo, Xin Man District, Ha Giang Province distance of 200 m with sensitive residential areas mentioned in the table 13 below; iii) fully covered for storage areas during rainy days; and v) temporary storage area will not be at construction site for more than 48 hours. (ii). Domestic solid waste 113. Impacts: Solid domestic waste consists of paper, cardboard, food waste, metal, wood, etc. It is estimated that worker will normally discharge 0.5kg of domestic waste each day. It is expected that there are about 30 workers per camp. Moreover, there will be approximately 4 worker camps, and each camp will daily generate 15kg of domestic waste. The total amount of expected waste from on the route reaches at 60kg/day. Unreasonable discharge can cause environmental impacts on sanitation, human health and landscape as well as create the habitat for disease-causing organisms. 114. Mitigation measures: Contractors must prepare garbage bins in the main locations where domestic waste is generated. One assigned urban environment company (URENCO) will be selected to collect waste everyday or weekly. (iii). Hazardous solid waste 115. Impacts: Hazardous waste during the construction process mainly comes from the maintenance of construction equipments such as oil, paint, asphalt, etc. Although the construction area is small; hazardous waste generation is still possible that could affect soil and water environment as well as regional ecosystem. Nonetheless, construction contractors should conduct mitigation measures in order to avoid loss of landscape and negative social impacts. 116. Mitigation measures: The storage of hazardous materials, fuel and oil should be minimized in the construction site. Hazardous materials will be stored in labeled containers and a covered area with waterproof floor. The area of stored hazardous substances will be clearly marked with a "Dangerous" sign and followed with the symbol of skull and crossbones. The collection, transportation, treatment and/or disposal of hazardous waste will be carried out by an approved waste management company which is pursuant to the Circular No.36/2015/TT-BTNMT (dated 30 June 2015) of MONRE on hazardous waste management. When small amount of asphalt road surface is removed, asphalt waste will be buried in waste rock and soil in disposal site at km 45+700 (in right of PR. No. 178) at Nam Chanh hamlet, Nam Dan commute, Xin Man town. The records on the storage, handling and transportation of hazardous waste (who handled, the location moved from/to, the date of transport, and responsibility) will be managed. 2. Impacts from gaseous emissions generated by the construction activities

117. Impacts: Excavation and material transportation activities will be the main sources of dust. Construction machines and vehicles will generate gaseous emissions (NOx, SOx, CO, CO2, etc.) when they are in operationThese gaseous emissions and dust could cause health problems for residents who live near the construction site, along the transportation route and the distribution pipe network. The impact is considered as negligible since the WTP, water tower and local road will be built in the high Hill around vacant land which is very far from the residential area of Nam Dan commune and Coc Pai Township. 118. The distance from the water treatment plan to the residential area of Nam Dan commune is about 4.2 km along the provincial road 178 (about 2.5 km along the crow flies) (see picture

Figure 8. Location of the water treatment station and residential area in Nam Dan commune

119. The location of clean potable water tank on the hill to the residential area of Coc Pai town

Water tank on the hill (Water Tower)

Figure 9. Location of the water treatment station and residential area in Coc Pai Township

120. The installation of the distribution network will be mostly manually conducted. Moreover, the construction time of water supply pipelines is short time. Therefore, the impacts of dust pollution and air pollutants due to installation of pipelines are minor and temporary. The table 11 below shows the sensitive points distributed in the main water supply area of the subproject. Table 11. The sensitive points distributed in the main water supply area of the subproject

Distance to the Sensitive point Location Type of pipeline pipeline (m) Steel pipe D200 D200 steel pipe The stream Ban Ngo bridge across the stream District General Hospital in Coc Pai The O pipeline - 32 Xin Man district township Pipe level 1 (D110)

- Avoid overloading construction materials because it may cause construction materials to drop;

- On dry days, watering three times per day at material gathering yards, access roads to construction site, at sensitive receptors as mentioned in table 11 and along the pipeline construction route.

- Waste generated from construction sites should be collected and transported to the treatment place immediately after collection.

4. Impacts noise generated by the construction activities

124. Impacts: Construction activities such as excavation, embankment, or operation of vehicles for transportation of materials will generate significant noise, which can affect local people’s daily life and workers who work at the site. Noise level generated from heavy construction machinery and equipment varies from 80 to 120 dB(A) and electric tools for construction work can generate noise level up to 115 dB(A). Impacts from noise during construction phase are unavoidable. The noise can make people feel stressful, fatigue; disrupt people’s concentration and affect people’s health…Sensitive receptors (Table 11 above) will also be affected by noise in the morning and at night time. Noise impacts are particularly sensitive in Xin Man District General Hospital; Xin Man High school boarding school; Xin Man High School; Xin Man Kindergarten, Xin Man’ People Commitee, Board quarters; continuing education center (old). However, these impacts on the schools, hospital, ect will only take place during the construction of pipelines. Construction of pipelines is carried out mainly by manual methods and at present this area does not have many noise sources, so the impact of noise is assessed as small. Moreover, the distance from the pipeline to the sensitive areas is quite far, ranging from 29 to 223 m. For large construction areas such as the construction sites for water treatment plants and Water tank (Water Tower), these are vacant land with no inhabitants, so this impact will mainly affect construction workers. 125. Mitigation measures: - Trucks are allowed to pass through residential areas from 8am to 5pm at speed not over 40km/hour. Horn honking should be limited near residential areas, sensitive receptors (Table 11) in the subproject area as well as along the transportation route. - Contractor has to submit documents proving that all equipment and machinery are tested/calibrated to meet requirements for vibration and noise as regulated in Vietnamese National Regulation QCVN26:2010/BTNMT on noise and QCVN 27:2010/BTNMT on vibration generated from construction activities - Prefer using of machinery and equipment with low noise, or noise dampening device and proper maintenance should be provided. - Prohibit use of machinery which generates noise level over 55 dBA at night time (from 10pm to 6am). In addition, other noise generating activities such as operation of heavy trucks, loading and uploading of goods, lifting girders and storing of materials…should be conducted at day time. - In case that the noisy machinery has to operate all night long near residential areas, detailed schedule should be considered and approved by CSC before commencement of work. Notification should also be sent to local people for this situation. - Turn off machines when not in use.

126. Impact: During the construction process, operation of the construction equipment and machineries can cause ground vibration. This vibration propagates in the soil environment, but will be drastically reduced by distance. The distance that can be significantly affected by vibration is about 10 meters from the source. Road compaction and pile driving are likely the most popular activities that cause vibration during construction phase of the project. Vibration may affect the stability of existing structures and discomfort people. The vibration can also affect the structure of existing buildings such as grade-4 houses and temporary houses within a range of 5-10 meters from the construction site. However, the use of vibration-generating machinery is mainly used in large sites such as construction of treatment plant and water tank. These construction sites are vacant land with no inhabitants, so these impacts are considered negligible. The construction of pipelines is carried out mainly by manual methods, so the impacts of vibration are small. Sensitive receptors affected by vibration are: Xin Man District General Hospital; Xin Man High school boarding school; Xin Man High School; Xin Man Kindergarten, Xin Man’ People Commitee, Board quarters; continuing education center (old). Moreover, the distance from the pipeline to the sensitive areas is quite far, ranging from 29 to 223 m. 127. Mitigation measures: - The contractor has to submit documents proving that all equipment and machinery are tested/calibrated to meet requirements for vibration as regulated in Vietnamese National Regulation QCVN27:2010/BTNMT on vibration generated from construction activities;

- The Contractor shall be responsible for compensating or reinstate the status of damages caused by vibration to adjacent buildings.

- Noise and vibration generation activities must not be conducted before 5 am and after 10 pm daily.

6. Impacts on the local traffic 128. Impacts: Construction activities on the subproject water distribution network may cause hindrance in traffic flow in the provincial road 178 and the Suoi Tien waterfall to the center of Coc Pai Township if no appropriate mitigation measures, especially in the Coc Pai Township. Therefore, children and pupils will have difficulty in getting to schools; and local residents must face with inconveniences on the way to Coc Pai market. Impacts will occur in a short time due to the installation of water distribution pipelines during the 12-month construction period. 129. During construction phase, traffic flow can be affected because the main pipelines under this subproject will be installed along the main roads of the Coc Pai township. In addition, the transport of materials also increases traffic on the road and local roads. These routes are a way for students to access to schools, from kindergarten to high school level. Local people often use the road for different purposes such as trade, agriculture, cultural exchange ... However, the consecutive construction method will be applied to shorten the interruption time of people. These impacts will affect the sensitive receptors shown in table 11: Xin Man District General Hospital; Xin Man High school boarding school; Xin Man High School; Xin Man Kindergarten, Xin Man’ People Commitee, Board quarters; continuing education center (old). Moreover, the distance from the pipeline to the sensitive areas is quite far, ranging from 29 to 223 m. These impacts only occur during the installation of the pipeline. Therefore, these effects are considered negligible. 130. Mitigation measures: To minimize the disturbance to local people, the contractor will

131. Impacts: Dust, gas emissions and noise generating from excavation, transportation of material, construction activities and operation of machines, etc will have direct effects on health of workers and local residents. Transportation of construction materials and construction activities on the existing roads can cause traffic insecurity and environmental impacts on the route, especially at sensitive receptors. Trenching method for installation of the pipeline can cause unsafety for people, especially pedestrians and children. Waste and wastewater from construction activities and worker camps can also create a favorable environment for the outbreak of some respiratory diseases of local people and workers. Accidents can occur if workers are not provided with safety equipment during construction and comply with construction regulations. The objects of this impact are workers at construction sites and residential areas along the pipelines. 132. Mitigation measures: - Provision of fire protection equipment and first aid kit at construction site and worker camp and make sure it is available for workers to take and use when needed;

- Preparing periodical orientation plan (such as weekly talks) for workers on health and safety issues related to their activities as well as proper use of personal protective equipment;

- Installing steel fence at all excavation sites, embankments and bridge construction site;

- Workers should be provided with appropriate protective clothes, such as protective boots, safety helmets, glasses, earplugs, gloves, etc., and the cost for these should not be included in worker costs;

- For traffic areas where there are working workers, barriers must be set up to protect workers from the means of transport;

- Workers should be provided with adequate water and hygienic water.

- Worker’s camps should be constructed with adequate drainage to avoid accumulation and stagnation

- Worker’s camps should be adequately equipped with toilets and sanitary equipment in accordance with local regulations to protect public health or to prevent soil, surface water and groundwater pollution. These sanitary equipments need to be maintained to ensure proper operation.

- Ensure all construction machines have reflectors

- Ensure that all drivers of construction vehicles and machinery are trained and have driving licenses,

- Ensure that there is a staff monitoring safety rules at construction site.

- The hotline number should be publicly disclosed at construction site so that people may contact for any issues related to community health and safety

8. Impacts on local community’s safety and business 133. Impacts: The construction and installation of water supply pipeline in Coc Pai Town will impacts on local communitys’ safety and business. For example, operation of construction equipment and vehicles can cause risks of accident to local people, digging road to lay pipeline can also cause difficulties in accessing business, house. See the table 11 on local community and business activities affected to construction activities. Business activities in Coc Pai Market could be affected due to installing the G and pipeline (D110). 134. During the process of installing the pipeline passing through the Xin Man highschool, Xin Man kindergarten and the People's Committee of Xin Man district, the Xin Man ethnic minority boarding school should pay attention not to affect the activities of students, teachers and parents when taking students to school. 135. Mitigation measures: - Ensure that the contract requires the contractor, before commencing work, to provides a construction plan with a detailed heath, safety, environment and traffic management plan - Inform local residents in advanced (at least 07 days) about construction and work schedules, interruption of services, traffic routes. - Put and maintain bulletin boards at the construction site, containing the following information: full name and phone number of the Contractor, Site Manager, Supervision Consultants and Subproject Owner, duration and scope of work. - Construction is carried out in a sequencing manner, section by section in a short period of time. Avoid the simultaneous construction and delay all over the construction activities - Contractors should provide lighting at a construction site at night; security guard staff at construction sites to regulate vehicles go out and in the construction site; - Put the road construction warning signs at the site all the time. - Avoiding the waste/material transportation during rush hours; - Construction by night time is not allowed - Limit the construction area; the construction activities are only taken in the site boundary - Assign staff to guide the traffic during transportation, unloading, and loading. 9. Degradation of surface water quality 136. Impacts: Water from construction activities/sites which can affect the environment and reduce water quality in surrounding area includes: (i) Runoff from construction sites; (ii) Drainage from construction equipment and truck maintenance; (iii) Runoff and drainage from unrestored borrow sites; (iv) Wastewater from work camps. Runoff from construction sites: Run-off water may erode the soil and flush it together with waste, oil and other matter eventually to the rivers and surrounding agricultural areas. Runoff typically

Basic Infrastructure for Inclusive Growth in the Northeast Provinces Sector Project Initial Environmental Examination (IEE) of Construction and Expansion of Domestic Water Supply System in Coc Pai Township and Adjacent Communes of Nam Dan, Ban Ngo, Xin Man District, Ha Giang Province contains high concentrations of suspended solids (SS) such as mud, organic matter that may decay and so increase chemical oxygen demand (COD), and may contain leaked oil from construction machinery. Water bodies may become polluted by SS, COD, oil and grease. The project will build a water distribution pipeline made by D200 steel across the stream at Ban Ngo bridge. Thus, the construction of this distribution pipeline should avoid impacts on the water environment at the stream crossing Ban Ngo Bridge and raw existing Dam of Suoi tien waterfall. 137. Drainage from operation and maintenance of construction equipment and trucks: contains substances, oils and suspended solids (SS). Maintenance and repairing sites should be drained to sumps to prevent these substances to reach water bodies. 138. Runoff and drainage from non-restored borrow sites: This water may erode land near the borrow site and cause suspended substances to enter watercourses, increase turbidity levels, damage the land and be visually unattractive. 139. Wastewater from work camps: Work camps will accommodate a number of people. The daily wastewater discharge is expected to be over 60 liters/day/person and contain food refuse, organic matter nutrients (nitrate and phosphate) and coliform bacteria. The water needs to be managed. In the absence of management, all of the above impacts would be caused and disease potentially spread. 140. According to surface water quality monitoring results of Ha Giang environmental state in 2010-2015 showed that surface water is quite clean. Hence, construction contractors must have measures to manage runoff, wastewater from equipment maintenance and operation, wastewater from workcamps, runoff from unrestored borrow pits as well as protect clean water sources. 141. Mitigation measures: - No scattering or disposing waste and soil into watersheds around the subproject area. - Residual excavated soil and stone will be reused for levelling low-lying areas or handed to local people for levelling their houses or to transport to treatment area. - The contractor will provide adequate drainage works at construction sites and at worker camps; store lubricants, oils in designated roofed areas with an impervious foundation situated at least 30m from water bodies. Sediment ditches and silt fences should be installed in small stream at Ban Ngo bridge to avoid runoff, erosion and silt release in to the water bodies. The existing drainage system shall be remained and ensured capacity; temporary pump system will be installed to pump water into other discharge points as needed. - Temporary gathering of construction materials and mixing concrete are not allowed within 30 meters from water sources. - Excavated soil from culvert construction and from the ditches should be collected and transported from the site within 24 hours. - No temporary disposal site shall be arranged near the water sources. - Loose construction materials such as cement, sand in material gathering yards need to be carefully covered by geotextile to avoid dust dispersion. In addition, the entire material collection area must be surrounded or fenced with temporary fences if necessary, to

Basic Infrastructure for Inclusive Growth in the Northeast Provinces Sector Project Initial Environmental Examination (IEE) of Construction and Expansion of Domestic Water Supply System in Coc Pai Township and Adjacent Communes of Nam Dan, Ban Ngo, Xin Man District, Ha Giang Province minimize the intrusion of stormwater runoff that sweeps sediments down to surface flows. - Arranging dustbins at workers’ camps and workers’ office to collect domestic waste. - Providing mobile toilets at workers’ camps and at construction site. 10. Impacts by the influx of construction workers 142. Impacts: About 40-50 workers will be mobilized discontinuously during the 12-month construction phase. The influx of construction workers can cause (i) a burden on local public services as electric and water supply; (ii) the risk of disease transmission to the subproject area; (iii) conditions for great spread of diseases such as sore eyes, cholera, flu and respiratory problems; (iv) risk of social problems such as gambling, drug addiction, prostitution and violence. The impacts would be on both workers and local communities near the construction sites. 143. Mitigation measures: (i) careful selection of workers' camps need to be approved by the PMU and located within effective drainage system to avoid the reproduction of mosquitoes and flies; (ii) registration of workers with local police while resident in the subproject area; (iii) the workers' camps should be regularly maintained to ensure the operation of efficient drainage system; (iv) workers should have health checks before starting work in the subproject and should be trained for living and working behaviors in advance; (v) engaging local people including unskilled or semi skilled jobs when they are able and willing to undertake them. Local people in the residential area of the communes as Coc Pai township, Nam Dan and Ban Ngo commutes will benefit from the subproject implementation. 11. Impacts on local infrastructure 144. Impacts: During construction of water distribution network, many roads in Coc Pai township will be excavated or affected by the storage and transportation of construction materials and wastes. Thus, the project construction can cause adverse impact on local infrastructure including electricity, telecommunication systems…, damage and interrupt public services. However, this impact is considered negligible because the layout and construction methods have been considered prior to construction process to minimize further adverse impacts. After laying the sewer system, road surface, sidewalk or local technical infrastructure will be restored by using the cost included in the package value. 145. Mitigation measures: - Compensation Policy for damages of private or public structures occurring during construction execution. - Damaged property will be restored to its former condition or compensated by contractors, immediately when occurred; - Under their contract specifications, the contractors will be required to take extreme care to avoid damaging property during their construction activities. Where damages do occur, the contractor will be required to repair the damage and may also be required to pay compensation to the affected families, groups, communities, or government agencies at the same compensation rates that are applied to all other assets affected by the Project F. Potential impacts and mitigation measures during the operation phase

1. Degradation of water pollution and inappropriate maintenance plan 146. Impacts: The Suoi Tien waterfall is located in the area of primitive forest of Xin Man district; it therefore is not polluted by cultivation activities. The water supply in this area has been tested to ensure the input standards for the treatment station (Table 8). Nevertheless, the

Basic Infrastructure for Inclusive Growth in the Northeast Provinces Sector Project Initial Environmental Examination (IEE) of Construction and Expansion of Domestic Water Supply System in Coc Pai Township and Adjacent Communes of Nam Dan, Ban Ngo, Xin Man District, Ha Giang Province monitoring of water quality should be regularly conducted to avoid unforeseen contamination or other intentional vandalism. Besides, treated water could also be contaminated since the WTP has problems or improperly operational procedures (chemical control). 147. Mitigation measures: 148. Arrange the fences surrounding the locations of water collection to avoid the movement of cattle. 149. Arrange warning signs at water collection locations and some key points along the water pipeline system. 150. Regularly check the location of water collection, pipeline system and promptly repair any problems. 151. The Xin Man CWMS will also regularly check the location of water collection, pipeline system and promptly repair any problems to ensure adequate water supply and quality. 152. Additionally, the Xin Man clean water treatment station should comply with the requirements of the Circular No.41/2018/TT-BYT dated on December 14, 2018 promulgating national technical regulation and regulations on inspection and monitoring of domestic water quality. The Center for disease control in Ha Giang province takes responsibility on regular and irregular external inspections of clean water quality for all water supply units of 500 households or more (or the designed capacity of 1,000 m3)/day and night in case of unspecified number of households). 153. The frequency of inspection, the number of samples, the measures and the time to fix the parameters that fail to meet the standards comply with the Circular No. 41/2018/TT-BYT dated on December 14, 2018. The frequency of monitoring is as follows: - Quality parameter of clean water in the group A: not less than 01 times per month; - Quality parameter of clean water in the group B: not less than once per six months; (Parameters of domestic water quality of the group A, B present in the Appendix 9) 154. Number of samples: 3 samples per test, 01 sample in the treated water tank of the water supply unit before putting into the distribution pipeline network, 01 random sample taken at the faucet used at the end of the distribution pipe network, and the remaining samples are randomly taken at the faucets used on the distribution pipeline network (including water distribution facilities such as tank trucks or water tankers). 155. The cost of sample analysis depends upon the annual regulation of Ha Giang province that is prepared by the Ha Giang Department of Natural Resources and Environment and approved by the Provincial People's Committee. 156. The Xin Man CWMS will coordinate with the DARD of Xin Man district will propagate to raise awareness of local people on water quality protection. 2. Accident risks during the operation of the plant 157. Impacts: Chemicals used in stations such as chlorine, especially chlorine under powder form, could leak and affect to the health of operators. Other work accidents may occur in case employees are properly untrained and comply with occupational safety procedures. 158. Mitigation measures: The station must be equipped with fire control systems and protective equipments for workers. Workers must be trained on occupational safety principles, emergency handling steps, appropriate treatment method and chemical storage. Among chemical

- Fixture of the substation: the substationwill be fixedif there is any failure of substation through monthly and irregular inspections. These activities include: cleaning substation(insulator clean, substation casing clean), cleaning and tighten the joints between substationcasing and ground system …

- Regularly check whether the transformer shell is oil leak or not; there is abnormal phenomenon or not; the sound of transformer operation is normal or not and the values displayed on the machine.

- Testing transformers (without power cut) must be performed once a shift. At the same time, check immediately when there is a sudden change: temperature, impact of the protective device.

VIII. GRIEVANCE REDRESS MECHANISM

A. Purpose of the mechanism

172. The Grievance Redress Mechanism provides an option to address concerns and grievances quickly through an open process to ensure that affected people and communities can exchange their dissatisfaction points about the activities of the subproject and their complaints can be resolved in time. The grievance redress mechanism is part of the IEE. The main objectives of the mechanism is to:

- Ensure disclosure of project information timely; - Provide a clear and transparent mechanism for the parties; - Ensure quick redress of concerns and problems at the lowest level if possible; - Timely compensate justified damages and losses; - Ensure trust for the community and relevant leaders; - Quickly and transparently address opinions of local people in accordance with the laws and regulations, especially for those who are affected by the subproject.

B. Subproject GRM redress process

173. Ha Giang PMU will establish a Grievance Redress Unit (GRU) which includes one environmental staff, one resettlement staff, one administration staff, one representative from local authority and some representatives from community. The GRU should have at least one female

Stage 1: Access to the GRM.

175. If a concern arises, the complainant will make his/her complaint known to the Ward/Commune People’s Committee (W/CPC) or to the grievance redress unit (GRU). Complaints can also be sent directly to the contractor through the hotline number provided for construction related matters such as noise, dust and other emergency matters which require immediate action. Contractors are required to report back to the GRU as well as the Construction Supervision Consultant on complaints received and resolved. For more complex construction matters, the GRU will forward the complaint to the contractors with recommendations for action. Stage 2: Submission and Registration. 176. The W/CPC or complainant will submit a written or verbal complaint to the GRU. The GRU will register the complaint. The GRU will register the complaint in the grievance registry and issue an acknowledgement of receipt within 5 working days of the complaint with information on when a decision will be made regarding the complaint. The GRU will handle all questions and queries of project related activities. Stage 3: Determine Eligibility. 177. The GRU will determine whether the complaint is eligible for the grievance mechanism. A screening procedure based on simple eligibility criteria will be established for the GRU. Criteria include: (i) the complainant is directly affected by the project; (ii) in case of representation, the complainant has a valid representation authorization; (iii) the complaint relates to environmental or social safeguards aspects of the project. If the complaint is deemed negligible, the complainant is informed of the decision and the reasons for ineligibility. A response on the eligibility shall be given to the complainant within 10 working days after receipt of the complaint. Stage 4: Assessment and Decision on Action. 178. If the complaint is eligible, the GRU will inform the complainant within 10 working days after receipt of the complaint that his/her complaint is eligible, including indication of the grievance assessment process and timeframe. The GRU, with support of relevant authorities, will conduct an assessment and gather information about the complaint and key issues and concerns to determine how the complaint might be resolved. The W/CPC and community members will participate in the assessment as necessary. If outside experts or technical information is needed, the GRU may seek such guidance and may request all parties concerned to participate in the GRM process. The decision on the solution will be by the PPC. The GRU will develop an action plan and identify responsibilities for the plan. This action plan will be reported directly to the complainant and/or W/CPC through the GRU. The response shall not be submitted later than 30 days after receipt of the complaint. If this timeframe cannot be ensured, the complainant shall be

- Number and type of complaints received

- Number and % of complaints that have reached agreement

- Number and % of complaints that have been resolved

- Number and % of complaints that are unresolved

183. The GRU will review the data on a quarterly basis to evaluate the functionality of the system, as well as to note the following:

- Failures to follow GRM procedures

- Delays in complaint resolution, particularly those that can affect project construction

- Most frequent types of grievances and complaints

- Location(s) producing the most grievances and complaint

184. If the complainant can also follow the procedures for compliants based on the Law on

185. There are four steps to address complaints received from stakeholders:

Stage 1: If a household or individual has any complaint, he/she can submit a complaint in written or verbal form to the reprentative of CPC-community monitoring board (usually the Deputy Chairman of the commune/town). The CPC will work with the PMU to solve complaints and a representative of the PMU will respond in written form to the complainant. The CPC will meet personally with the aggrieved affected household and will have 30 days and a maximum of 60 days after the lodging of the complaint to resolve the case. Nonetheless, it depends upon whether it is a complicated case or the distance of remote area. The CPC secretariat board is responsible for documenting and keeping file of all complaints that it handles.

Stage 2: If after 30 or 45 days (in remote areas), the complainant do not received or is unsatisfied with the CPC decision taken on his/her complaint, the complainant may bring the case, either in writing, to any member of the District People’s Committee (DPC). The DPC in turn will have 30 days or a maximum of 70 days after the lodging of the complaint to resolve the case. However, it depends upon whether the case is complicated or the distance in remote area. The DPC is responsible for documenting and keeping file of all complaints that it handles and will inform the District Resettlement Committee (DRC) of any decision made. The DRC is responsible for supporting DPC to resolve affected household’s complaint. The DPC must ensure that the complainant is notified of the decision made.

Stage 3: If after 30 days or 45 days (in remote area), the complainant does not receive information from the DPC, or if not being satisfied with the decision made on his/her complaint, the complainant may bring the case, either in writing, to any member of the PPC. The PPC has 30 days or a maximum of 70 days to resolve the complaint if the case is complicated or from a remote area to the satisfaction of all concerned; nonetheless, it depends upon whether the case is complicated or the distance of remote area. The PPC is responsible for maintaining records of complaints received, action taken and outcomes.

Stage 4: If efforts to resolve disputes using the grievance procedures remain unresolved or unsatisfactory, after a period of 30 days, the complainant has the right to bring the case to a Court of law for adjudication. The decision of the Court is binding on all parties.

Complaints from AHs or APs

If the complaint is not resolved within 30 days (or 60 days in the case of a remote area) CPC / PMU Stage 1

If the complaint is not resolved within 30 days DPC Stage 2 (or 45 days in the case of a remote area)

If the complaint is not resolved within 30 days CPC Stage 3 or a maximum of 70 days

An operation and inspection schedule should be included in the operational procedure of the plant for all processing equipment and chemical storage. Chlorine containers must be stored in a dry place and away from non-toxic materials.

196. An environmental monitoring program will be outlined to monitor the environmental impacts arising during the project implementation, including as: (i) Monitoring the surrounding environment: Only typical pollutants arising from the construction that are required to be monitored in accordance with existing standards and regulations of Vietnam with a frequency of at least once in every 6 months, the supervisory positions will be expressed explicitly in a diagram with annotation and coordinate under current regulations. (ii) Monitoring will capture impacts identified during the contract supervision including as erosion, sediment, changes on surface water level, groundwater, and impacts on the socio-economic objects (if any). (iii) The monitoring locations will also be shown in a diagram with annotation and coordinate under current regulations. 197. The Ha Giang PMU or ESS under Loan Implementation Consultants (LIC) will implement environmental monitoring program during the construction phase. In the operation phase, the CWMS and DARD office in Xin Man district will implement this environmental monitoring program. Compliance Monitoring 198. Table 16 below shows the monitoring program for the compliance on various provisions of the EMP during the construction and operation phases. The EMP needs to implement a number of measures during the detailed design phase (for example, the incorporation of environmental design measures into the detailed design, the EMP update, etc.) and this will be confirmed by the PMU to ADB. During the construction, the majority of mitigation measures will be conducted by the contractors, and environmental performance monitored by the ESS, in terms of implementation of such measures. The timing or frequency of monitoring is also specified in Table 16. During the operation phase, the EMP implementation shall be the responsibility of the CWMS in Xin Man district. 199. Prior to the subproject implementation, the IEE and EMP will be updated and amended, as necessary by the ESS before the detailed designs completed and contract agreement established. Such updating shall be based upon the reconfirmation and any additional information on the assumptions made at this feasibility stage on location scale and expected conditions of the subproject. Environmental quality monitoring 200. The ESS conducts environmental monitoring for air quality, noise and surface water quality. Sampling will be conducted before field works at specific locations start. During the construction, the ESS will conduct quarterly monitoring of surface water quality, air quality and noise in the same locations to be sampled during the pre-construction. Furthermore, additional sampling and analysis of other parameters will need to be conducted (if necessary) to confirm complaints and/or investigations of the subproject pollution events. The Xin Man CWMS will be responsible for quality monitoring of treated water in the first year of operation.

E. CAPACITY BUILDING

202. In Viet Nam, the environmental assessment process is established but environmental awareness and capability for the EMP implementation in infrastructure projects of both the executing agency and implementation agency (PMU) are fairly limited and in development duration. The PMU safeguards staff is usually responsible for many different tasks and do not have good background on safeguards issues. Specifically, the engineer is usually in charge of the environmental monitoring. Thus, their capacities are unsuitable to check the adequacy of the subproject EMP. In parallel with the IEE establishment, the PMU has submitted an environmental management plan to the Xin Man DPC for approval. The PMU was established under the direction of Ha Giang Department of Planning and Investment (DPI) with an employee has been assigned as ESO. 203. The most significant challenge is the lack of human and financial resources and necessary

X. CONCLUSIONS AND RECOMMENDATIONS

204. The implementation of the subproject “Construction and Expansion of Domestic Water Supply System in Coc Pai Township and Adjacent Communes of Nam Dan, Ban Ngo, Xin Man District, Ha Giang Province” will improve conditions and enhance water supply services for local residents, especially rural people and poor people. The subproject implementation could bring the access of sanitary water resource to meet their production and tourism demand. 205. The negative environmental impacts from the upgrading works will mostly take place during the construction stage. All of the impacts during construction phase should be very predictable and manageable and with appropriate mitigation and few residual impacts are likely. Additional human and financial resources will be required to improve environmental capability and to progress and achieve necessary statutory compliance and environmental clearance certification for the subproject or associated activities that also require environmental permits under the environmental laws of Viet Nam – LEP 2014. 206. No further or additional impact assessment is considered necessary at this stage. At the implementation stage, PMU through ESP will develop detail EMP to monitor the schedules of mitigation measures and conduct of environmental effects monitoring activities. EMP must be updated to ensure effective environmental monitoring and should be develop follow-monitoring plan as specified in the EMP. With these measures in place, environmental impacts of the subproject should be manageable and will not result in any residual impacts, which are above accepted environmental standards.

Screening Questions Score Remarks12

Location and Is siting and/or routing of the project (or its 0 Design of components) likely to be affected by climate conditions project including extreme weather-related events such as floods, droughts, storms, landslides? Would the project design (e.g. the clearance for 1 Dam (blocking the flow of water) bridges) need to consider any hydro-meteorological from upstream of Suoi Tien parameters (e.g., sea-level, peak river flow, reliable stream should consider hydro- water level, peak wind speed etc)? meteological parameters (water level, flow) that will affect to water supply for the subproject area. Materials Would weather, current and likely future climate 1 Selecting construction material and conditions (e.g. prevailing humidity level, temperature for raw water pipelines (from Maintenance contrast between hot summer days and cold winter Suoi Tien stream to water days, exposure to wind and humidity hydro- treatment station) is appropriate meteorological parameters likely affect the selection of for the climate condition of the project inputs over the life of project outputs (e.g. subproject. construction material)?

Would weather, current and likely future climate 1 Climate conditions will affect conditions, and related extreme events likely affect the selecting material to construction maintenance (scheduling and cost) of project output(s) of the raw water pipelines and ? water treatment station.

Materials relate to construction cost and scheduling to ensure that sustainable construction with weather condition Performance Would weather/climate conditions, and related 0 of project extreme events likely affect the performance (e.g. outputs annual power production) of project output(s) (e.g. hydro-power generation facilities) throughout their design life time? Options for answers and corresponding score are provided below: Response Score

12 If possible, provide details on the sensitivity of project components to climate conditions, such as how climate parameters are considered in design standards for infrastructure components, how changes in key climate parameters and sea level might affect the siting/routing of project, the selection of construction material and/or scheduling, performances and/or the maintenance cost/scheduling of project outputs. 133
