1 INTRODUCTION

1.1 Purpose of the IEE Update Report and the Project Background

Purpose of the IEE Report

1. The Government of Viet Nam has requested the Asian Development Bank (ADB) for technical assistance to support the implementation of the Central Region Rural Water Supply and Sanitation Sector Project (CRRWSSSP). The CRRWSSSP supports the National Rural Clean Water Supply and Sanitation Strategy (NRWSS) up to 2020, the Comprehensive Poverty Reduction and Growth Strategy and Viet Nam’s commitment to achieving the Millennium Development Goals for rural water supply and sanitation (RWSS).

2. The review, revision and subsequent updates to the IEE report are put in order to comply and fulfil the requirements of the Vietnamese Decree No.29/2011/ND-CP dated 11 April 2011, Circular No.26/2011/TT-BTNMT dated 18th July, 2011 by MONRE and to the ADB policies on Environmental Assessment Guideline 2003 and Safeguards Policy Statement 2009.

3. The IEE report document will be submitted and included among the documents for review required for the Subproject Appraisal Report (SAR) of Nghe An Pilot Water Supply and Sanitation Subproject.

CRRWSSSP Background

4. The Central Region Rural Water Supply and Sanitation Sector Project (The Project) will contribute to the Vietnam Rural Water Supply and Sanitation (RWSS) strategy, which states that by 2020, 100% of the rural population will (i) have access to clean water with a minimum volume of 60 litres per capita per day1; (ii) use hygienic latrines; and (iii) practice proper personal hygiene.

5. The Project is designed as a sector investment project. The Project will result in better health and living conditions of people living in rural areas in the Project provinces. The output of the Project will be access to clean water and hygienic sanitation for about 350,000 rural people in approximately 30 communes in the six Project provinces in the central region of Viet Nam: Thanh Hoa, Nghe An, Ha Tinh, Quang Binh, Quang Nam, and Binh Dinh. The Project will comprise about 24 Subproject, divided into 3 batches with 6-9 Subprojects of each.

6. Each Subproject includes the construction and operation of a sustainable piped water supply system for one commune (or several communes), and improved household hygiene and public sanitation in the Subproject area. The Subproject implementation will follow a community-based approach to ensure that it meets the demand of local population. It will also focus on capacity building to enable provincial government agencies, PPMUs, communes and villages to conduct the Subproject by themselves properly.

1 According to project design the minimum volume of water in CRRWSSSP is 80 liters per capita per day.

Reviewed the REA and evaluated the screened potential impacts as a consequence of the design and technology to be used, issue and concerns relative to location and laying of main line and distribution lines that will negatively affect the cultural and historical values located in the communes of the Subproject area; siting/design, construction and operation & maintenance phases, to distinguish those that are likely to be significant for a particular subcomponent and would warrant further study.

Subproject site visit include field validation of the findings and information on the IEE report including the preliminary design, location of construction sites for water reservoir, Water Treatment Plant (WTP), pumping stations, raw water source and other required structures and facilities for the water supply system.

Validations of the technical description of the Subproject as described in the Feasibility Study Report are integrated into this IEE Update Report. Additional data and information from the Provincial and Communal Authorities and the workshop participants were incorporated into this report. The final updates were supplemented by the needed data and information on the following:

The baseline information on the relevant physical-chemical and biological environment, also additional data and information needed regarding the socio-economic conditions in the subproject area; cultural and historical sites and public consultant meetings;

Revised and prepared an updated Environmental Management Plan (EMP) and Environmental Monitoring Plan (EMOP) with the ADB templates, recommended monitoring of environmental baseline parameters; and

Revised institutional arrangements and responsibilities for the implementation of the EMP and EMOP.

2 DESCRIPTION OF THE SUBPROJECT

2.1 Type of Subproject

15. The CRRWSSSP is designed as a sector investment Project, The Project is expected to improve the health and living conditions of the people in the rural areas of the 6 Project provinces in the central region of Vietnam. The Project will be implemented for a period of five years comprise of 24 Subprojects, divided into 3 batches with 6-9 Subprojects of each. Nghe An Subproject is among the Six Pilot Subprojects that have been chosen for the first batch to be financed under the ADB loan.

2.2 Category of Subproject

16. The screening and the environmental categorization of the Nghe An Water Supply and Sanitation Subproject (WSSS) was performed using the sector-specific Rapid Environmental Assessment (REA) Checklist of ADB for water supply sector division. Based on the REA screening results, the Subproject is unlikely to cause significant adverse impacts on the bio-physical environment, forests or protected areas or to cultural and historical sites located within the coverage of the Subproject area. As the REA Checklist has indicated no significant impacts to the above environmental aspects, the proposed water supply scheme therefore is classified as Category B under the ADB’s



5


environmental classification. For projects in this Category an Initial Environmental Examination (IEE) will have to be prepared to determine the need for an Environmental Impact Assessment (EIA).

17. Pursuant to the Decree No.29/2011/ND-CP dated 18th April, 2011, the environmental categorization is determined based on the type, scale and capacity of the proposed project. The Nghe An water supply scheme requires the volume of 1,700 m3/ day to be sourced from the surface water. Nonetheless, under the said Decree, it is required to apply and prepare an Environmental Protection Commitment (EC). The preparation of the EC document shall conform to the guidelines of the Circular No.26/2011/TT-BTNMT. The EC document shall be submitted for registration to the concerned District People’s Committee (DPC).

2.3 Description of the Subproject

18. With the objectives of the proposed Subproject to provide access to a sustainable, clean and reliable water supply system and promotion of household and public sanitation, the Subproject will have two major components: (i) Piped water supply system; and (ii) Promote public hygiene and provision of sanitation facilities.

2.3.1 Piped Water Supply System

19. The Piped Water Supply System is designed to meet the demand of the population of 14,540 people living in Subproject area by 2020, with capacity of 1,700 m3/ day and total length of transmission and distribution pipeline system is 137.8 km. The system will consist of: (i) a raw water reservoir; (ii) raw water pipeline; (iii) water treatment plant; (iv) pumping station; (v) transmission and distribution pipeline system; and (vi) house connections or communal taps, with water meters.

20. Operational and sustainable piped water supply system will have to: (i) provide water continuously at quantities not lower than 80 litres per capita per day; (ii) tap water will be clean and safe for human consumption without further treatment; (iii) the number of breakdowns will be less than four times per month and these will not last more than 2 hours each; (iv) the water tariff will cover operation, maintenance and depreciation costs; (v) the water bill per household, based on 80 litres per capita per day, will be less than 3% of average monthly income.

Raw Water Source

21. The proposed water source for the Piped Water Supply system will be abstracted from irrigation canal No.1 - directly takes water from Lam’s river via barrage Do Luong. This canal system has capacity of maximum water quantity Qmax = 40 m3/s. Currently, it serves water for agriculture and living water demand of Yen Thanh, Dien Chau and Quynh Luu districts with population of about 900,000 people. For details of this surface water quality, see Chapter 4.1.2.

22. The raw water reservoir is designed to (i) contain the water volume ensuring sufficient water for about 22 days for the Water Treatment Plant (WTP) when irrigation system stops supplying water for maintenance annually; (ii) pre-sedimentation of suspended solids of raw water before pumping into the WTP. The reservoir will be constructed next to the canal No.1 within the Water Treatment Plant area.

Water Treatment Process Diagram

23. Water Treatment Technology and Process has been selected based on quality of the raw water source, capacity of the water treatment plant, management and operation requirements, and available terrain that facilities will be placed. In this case, surface water from raw water reservoir will be pumped to the Water Treatment Plan (WTP). After treatment, the treated water will be pumped through the transmission and distribution pipeline system to the house connections.

25. During construction phase, there will be a large volume of soil arising from dredging reservoir and excavating for the facilities of the WTP. This soil will be transferred to the mining soil land as the CPC’s requirement at a distance of 2.5 km from construction site.

26. The wastewater arising from the water treatment process is mainly backwash water (mixture of water and inorganic sediment) which is discharged from settling basin and rapid sand filters. It will be collected into the sludge lagoon, from which settled sediment will be periodically removed and transferred to the dump site. Clarified water will overflow through the WTP’s drainage system to the existing irrigation drainage which will discharge wastewater to the downstream and then to the sea.

2.3.2 Promotion of Households and Public Sanitation

27. The promotion of public sanitation will be complimented by construction of latrines for 5 units of the schools and 1 unit of the commune health station located within the commune. List of them is shown in Table 1.

(ii) new construction of 1,212 hygienic latrines and renovation of 97 existing latrines for non-poor households by providing them a credit up to a maximum of the estimated full cost of a latrine, estimated to 6 million VND/unit.

29. In promoting construction of latrines among HHs, the QCVN 01:2011/BYT National technical regulation on Hygienic condition for Latrines (attached with the Circular No.27/2011/TT-BYT dated June 24th, 2011 of the Ministry of Health (MOH), becoming effective on January 01, 2012, will be adhered to ensure the environmental and health safeguards of the latrines build under the Subproject. Following the above standard, types of latrines will be endorsed:

Dry latrine: - Dry underground pit; - Dry on-site latrine (double vaults or single vault).

Pour latrine: - Septic tank latrine; - Pour flush latrine.

30. The regulations of construction given in the QCVN 01:2011/BYT will be followed to ensure that correct type of latrines are built in any given location considering location specific conditions such as water-logged and flooded areas, etc., to minimize any potential adverse impacts on groundwater and environment. This standard indicated the following conditions: except for Septic tank latrine, the latrines must not to be built in the areas that are usually flooded or water logged to avoid or prevent contamination or spill of polluted and gray water to the ground water. In case the latrines will be constructed in the flooded or water logged area, it must be built at controlled level to avoid flooding and water logging to the area.

31. According to the Project Administration Memorandum (PAM), Project will support Double vault composting and Pour flush latrines for household use. For the Subproject, hygienic Double vault latrine and Septic tank latrine are proposed to be constructed.

3 DESCRIPTION OF THE ENVIRONMENT

3.1 Physical and Ecological Resources

3.1.1 Climate

39. The climate is monsoon tropical, hot in summer (from May to September); and cold and drizzling in winter. The average temperature is about 230 C, with the recorded temperature maximum and minimum of 6 and 400C respectively. The average rainfall is 1,800 mm but 80% of the total rainfall is distributed in May and September.

3.1.2 Topography

40. Dien Yen commune belongs to the coastal areas of Vietnam. The terrain is quite simple, flat, and little separated. Topography is reduced gradually from West to East on the coast; and the average elevation is 5 - 8 m above sea level.

3.1.3 Geology and Soils

41. Engineering geological condition of the region retains general geological characteristics of Dien Chau district which belongs to coastal sedimentary plain. Stratum structure is composed of several layers of sand with yellow, brown, and gray colours. The average load capacity of the ground ranges from 1 to 1.5 kg/cm2.

42. The soil in the Subproject area is predominately laterite and exhibits characteristics such as rapid drying to a hard surface, extremely slippery when wet, extremely fine dust when loose and dry. Further, this soil also erodes very easily given that it contains very little organic material.

3.1.4 Water Resources

Ground water

43. There are three ground water aquifers that can be exploited for domestic use: a) Interstitial aquifer created in Holocene sediment; b) Interstitial aquifer in Pleistocene sediment; and c) Interstitial fissure aquifer - Cacter in Carbonate sediment. Ground water layer of the Holocene aquifer contains large volume according to the hydro-geological map of Nghe An province. Nevertheless, ground water is polluted by saline intrusion, iron compounds and agricultural activities.



13


Surface water

44. Ca river through Nghe An province and La river through Ha Tinh province are two main up-stream sources of the Lam rive which is largest river in the Northern Central region of Vietnam. The irrigation system with branded canal No.1 directly takes water by gravity from Lam’s river via barrage Do Luong along 27 km to the Subproject area. The Center of High-tech Development - Institute of Environmental Technology in Hanoi City has taken the water samplings and analyses of water quality from this canal for the selection of water supply for the Subproject.

3.1.5 Forests/ Protected Areas

45. Based on consultation with Nghe An provincial DONRE and local people, no protected areas or known rare or endangered species were found anywhere within the 2-km radius of the Subproject area.

3.2 Economic Development

3.2.1 Industries

46. In the Subproject area, there is no industry. People live by agriculture, animal husbandry, poultry and aquaculture production or small trade services.

3.2.2 Infrastructure Facilities

47. In Dien Yen commune, local people are using untreated water obtained from shallow aquifer wells (2÷4m deep), irrigation canals, and rainwater. The iron and salinity contents are high in the shallow wells and dug wells, especially in dry season (October - April). Water from irrigation canals is turbid and contaminated by wastewater from upstream communities and local human activities with many contents such as fertilizer, pesticides and solid waste. Rainwater is only available in rainy season and not enough for domestic use.

There are 5,433 wells and rainwater tanks of the households in the commune, including:

2,842 shallow wells, of which hygienic unit are 198, accounting for 7%; 719 drilled wells, of which hygienic unit are 146, accounting for 20%; and 1,872 rainwater tanks.

48. This serious condition of the water sources in the Subproject area causes local people, accounting for 86% of total residents, are often forced to use unhygienic water for domestic purpose. The percentage of diseases related to using unclean water (such as skin diseases, gynaecological disorders, and dysentery) is high.

49. There are only 16% of people in the Subproject commune using hygienic latrines. Common model of the latrine in the commune is composite double vault. The rest are septic tank latrine 231 units, pour flush latrine and dry underground pit. Many households are using latrines that their disposal discharges directly to the receiving sources such as ponds, lakes, and ditched canals.

50. The sewerage network had been concreted and ditched mainly along the communal, village and hamlet roads. Within the residential areas, there is no sewerage system, so wastewater from households discharges into house gardens. In some places wastewater is



14


stagnant along the road making environmental pollution. Flood often occurs during rainy season.

There is 60% of the solid waste has been sorted at households and collected to the village collection points and then transferred to the communal dump site.

51. Nghe An is one of the important hub of transportation throughout the country. It has diversified and developed transportation, including land transportations, railway, river ways, an airport and sea ports.

52. Transportation in Subproject area is very convenient because Dien Yen commune is located along East and West side of National Road No. 1A. 2.8 km of the National Road No. 1A, 3.5 km of National Road no. 48 and 2.5 km of Provincial Road 205 pass through this commune. The inter-communal roads and inter-hamlet roads are asphalted or concreted while some intra-hamlet roads are still unpaved roads and muddy during rainy season.

3.2.4 Land Use

53. Total natural land of Dien Yen commune is 1,522.52 ha, of which croped land (rice cultivating and annual vegetation) account for the biggest proportions of land use 35%. Residential land, accounting for 4.6%, formed based on the four old residential areas there are Yen Ly Dong, Yen Ly Ngoai, Yen Ly Thuong and My Quan villages.

4 SCREENING OF POTENTIAL ENVIRONMENTAL IMPACTS

61. The potential environmental impacts of the proposed Subproject were screened using the Rapid Environmental Assessment (REA) checklist of the ADB, and the GoV Decree No.29/2011/ND-CP, which generally categorized projects in several types:



18


(i) Projects listed in Appendix I as Strategic Projects and Master Plans will be subjected to Strategic Environmental Assessment (SEA) reporting;

(ii) Projects listed in Appendix 2 will be subjected to an Environmental Impact Assessment (EIA) reporting; and

(iii) Projects listed in Appendix 3 will be subjected to EIA to be appraised and approved by the Ministry of Natural Resources and Environment (MONRE).

62. Those projects not listed in Appendix 1, 2 and 3 will be required to prepare and register an Environmental Protection Commitment (EC) to the District People Committee.

63. The daily water supply requirement of the Nghe An pilot Subproject is 1,700m3 and will be sourced from surface water of the irrigation canal. Based on the above mentioned Decree, the scale or magnitude of the proposed Subproject water supply scheme is small and not listed in Appendix 1, 2 and 3 of the Decree. Nonetheless, the Subproject is required to apply and submit an Environmental Protection Commitment to the concerned District People’s Committee for registration and approval. Under the ADB’s REA Checklist, the Nghe An Subproject has been classified as Category B and requires an IEE report.

64. The screening processes were supplemented with field investigation surveys and evaluation of the existing environmental conditions in the Subproject location to reassess and confirm the potential impacts identified to be generated on the physical environment such as soils, air, vegetation, trees, protected species of flora and fauna, landslides, forest land protected areas, cultural/historical sites, bodies of water, river system.

4.1 Impacts Due to Location

4.1.1 Water Supply Facilities

65. The Subproject water supply system will include installation and construction of structures and facilities such as: raw water reservoir; water treatment plant including settling basin, rapid sand filter, raw water pipeline, treated water reservoir and chemical storage, sludge lagoon, administrative house; transmission and distribution pipelines system; and waste water drainage system. It will also provide for the construction of guard houses, entrance gate, fence, garage.

66. The proposed sites for the raw water reservoir and Water Treatment Plant (WTP) associated structures will be located in an agricultural land in Hamlet 6 of Dien Yen commune with the area of 30,794 m2. This land is public utility land belongs to management of Dien Yen Commune People's Committee. Presently it is cultivated for rice production and fishery pond by household without written contract with Dien Yen CPC. There will be lost of rice crop but of only small farming income. An access road to the WTP is existing concreted inter-field road which is also the village road of the commune.

67. Main transmission pipelines from the WTP to the villages will go through the field site but they are installed closely along the inter-field road. Through the villages, pipelines are designed to be installed under pavements and in corridor area of traffic road in order to avoid or minimize impacts to road and people daily activities. Temporary land acquisition will be required and they may temporary disrupt the cultivated land of some households and traffic road but this land will be restored to their pre-Subproject condition right after completion of each of pipe-line unit.



19


68. Within the proposed sites for the construction and installation of the building, no structures and facilities, forest land, heritage site will be encroached by the proposed Subproject. Neither environmentally sensitive sites nor precious ecological areas will be affected. Moreover, there will be no impact on protected and red-listed species of flora and fauna in the proposed subproject sites. Further, there will be no impacts on cultural use of lands by indigenous minorities or impairment of aesthetics in the environment will not occur.

69. Also, Subproject facilities are unlikely to impact on the natural drainage pattern and no local flooding will occur. The structures in flood prone areas will be protected from floods by constructing at a higher elevation and providing adequate drainage around the structure. These interventions would not impact the local area flooding conditions as the constructed areas will be very small and within agricultural areas.

70. The total land recovery required for Subproject facilities (including raw water reservoir, WTP facilities and embankment) is 30,794 m2 permanently. Temporary land acquisition for transmission and distribution pipelines system is 42,000 m2.

71. There are 3 HHs (1 HH losing crops and 2 HHs moving graves) and 1 Commune People’s Committee are affected by land acquisition. Land recovery and resettlement plan has been prepared according to ADB and GoV resettlement policies to address the affected parties.

72. Cultural and historical sites namely: the Phung Chi Kien national historic site in Trung hamlet 1, My Quan village, and Dinh Chay provincial historic place in Hamlet 8, will be given due attention in the final engineering design of the Subproject in order to avoid encroachment and impairment of the sites and its structures.

4.1.2 Water Sources

73. Site selection for water abstraction was based on the availability of adequate quantity of good quality (reasonably treatable) water sources. Subproject follows relevant guidelines/regulations and policies of the GoV and MONRE at the National level or DONRE at Provincial level. Table 3 shows the raw water quality analyses taken sampling from the irrigation canal No.1.

Column A2: The critical parameters of water quality which used for purpose of water supply but it must be treated with the appropriate treatment technology.

74. The latest laboratory analysis of water quality taken in December 2011 has indicated that it meets the Vietnamese standard requirements in QCVN 08:2008/BTNMT - National technical regulation on surface water quality. Based on the result, the raw surface water abstracted from irrigation canal No.1 has been selected as water source to supply to the Subproject Water Treatment Plant of Dien Yen commune. However, this water source is exposed to pollution from many living activities such as domestic waste, fertilizers and chemicals from agricultural production. During WTP operation, the raw water must be tested periodically to ensure water source quality meets the Vietnamese standard requirements. Communal agencies need to agitate for raising people awareness of water source protection, simultaneously.

75. Hydrological data support the availability of adequate water resource throughout the year in selected source to meet the full demand including that of dry season demand over the long term. The rate of water abstraction from the irrigation canal is about 0.07% of the flow and it has been estimated to cause no water imbalance impacts on the current users. The Nghe An Northern Irrigation Company, the Management Unit of canal No.1 has issued the letter permitting abstraction of water from canal No.1 for water supply Subproject by PCERWASS. Nevertheless, storage facilities are incorporated to overcome any unexpected low flows, e.g. water storage adequate for one month in case of irrigation canal shut down for maintenance. The residential time of water in such storages is very short for any development of algal blooms, etc. Similar storage for water from irrigation canals in the same irrigation system has already proved this.

76. Potential source have been tested for water quality to ensure that the source water can be treated to meet QCVN 01:2009/BYT - National technical regulation on Drinking Water Quality (attached with the Circular No.04/2009/TT-BYT dated 17 June, 2009 of Ministry of Health (MOH). Water treatment units (e.g., aeration tower, clarification, filtration, chlorination, etc.) for system are designed to address site specific conditions as identified by the water quality analysis. This adherence to GoV regulation minimizes the chances for any adverse impacts related to the location of the water abstraction with regard to the environment and quality.

4.1.3 Household and Public Sanitation

77. Public and Household latrines will be built considering specific conditions such as water-logged and flooded areas to minimize any potential contamination of the groundwater.



22


78. All latrines for the households will be designed and constructed according to the Guideline for design, construction, use and maintenance of household latrine - Published on 2010 by Medical Publisher (MOH).

79. All latrines for households will also comply with the QCVN 01:2011/BYT National technical regulation on Hygienic condition for Latrines (attached with the Circular No.27/2011/TT-BYT dated June 24th, 2011 of the Ministry of Health (MOH) to ensure the protection of the environment and to safeguard people’s health.

80. Latrine for the school will be designed following the Toilet facilities model for Kindergarten, Primary and Secondary Schools (attached with the Decision No.1486/QD-BGDDT dated March 31st, 2008 of the Ministry of Education and Training (MOET)).

81. According to the statement of Communal authorities, the improvement of drainage/sewerage system will be considered in another project for the entire of the commune. It is expected to adequately and properly discharge the sewage, including the gray water resulting from new water supply Subproject.

4.2 Impacts Related to Design

82. The potential impacts issues and concerns related to the design that would bring possible adverse impacts on the environment and public health.

4.2.1 Water Supply Facilities

83. Potential impacts include:

Unsatisfactory raw water quality, the pollutants of which could not be removed using available treatment processes;

Inadequate protection of intake works from surface run-off pollution, which could lead to unsafe water (if treatment is inadequate);

Inadequate design of facilities for receiving, storing, handling sodium hypochlorite solution so that, with improper O&M, workers will suffer from toxicity of chemical escaping to the environment;

Absence of disposal facility for sludge from water treatment facilities; Increased gray water production that could not be managed due to absence of, or

inadequate, drainage facilities; and Water distribution lines in the drainage canals, which exposes leaking water pipes to

contaminated water.

4.2.2 Household and Public Sanitation

84. Due to local climate and soil conditions, Septic tank latrines and Double vault latrines are proposed to be designed and constructed for the Subproject area to avoid leach of black water into water sources or contamination of the groundwater and to ensure the protection of the environment/public health.

4.3 Impacts During Construction

85. Even if most of the potential significant impacts are avoided by selection of proper sites, negative temporary impacts may occur mainly during the construction phase, if adequate



23


attention is not paid to control them. The potential adverse impacts at varying magnitudes are discussed below.

4.3.1 Air Quality

86. Increase in total suspended particles from clearing and grubbing and excavation activities; movements of construction equipment; and emissions and noise from operation of construction equipment will have substantial impact when construction of facilities are in settlement centers or in densely populated areas. Nevertheless, these can be easily be mitigated by proper construction methods. The distribution and network of pipelines will have a wider distribution or coverage the residential areas and road sides. But it relatively will not have greater impacts as compared to the construction of other required structures or facilities for the Subproject.

4.3.2 Physical Environment

87. During construction, exposed soils, generated construction debris, sewage, hazardous wastes may affect nearby water bodies, unless construction sites are properly managed.

88. Soil erosion from construction activities will have some impacts if land clearing and construction activities are not properly planned and executed. Flooding (intermittent or perennial) in adjacent areas could be a consequence of heavy siltation in nearby drainage or stream channels caused by inadequate management of exposed ground surfaces, removed topsoil, soil stockpiles and construction debris.

89. Adverse impacts due to quarrying of construction material (rock particles or coarse grains, sand or fine grains) or borrow pits is unlikely as all such material will be procured from the quarries legally operating with required permits from relevant authorities.

4.3.3 Biological Environment

90. If siltation of, construction wastes into nearby water bodies is uncontrolled that may have detrimental effect to aquatic/marine flora and fauna downstream.

91. The land for construction of Water Treatment Plan is a cultivated rice field and fishery pond. People are informed not to continue cultivating in this land before commence of construction. No rare or endangered species occur in the Subproject area. The main transmission pipes will be located within the right of way of the existing inter-field and village roads. No land degradation will happen within the Subproject area.

4.3.4 Socio-Economic Environment

92. Little or no impact is anticipated on land use since the sites are typically located on agricultural area. Permanent agricultural land acquisition is about 30,794 m2 belonging to the Communal People’s Committee. Total temporary affected land (along the roads) for construction of transmission and distribution pipelines is 42,000 m2. No land acquisition is from residential area.

93. Construction vehicle noise, dust, and emissions near construction sites and on local roads can be a nuisance to communities. Under similar circumstances, excavation and construction activities may cause noise and dust; vibration and noise from cement mixers, generators and other equipment.

94. Adverse impacts on the public in terms of traffic, inconvenience, disruption of socio-economic activities, and disruption power supply, blockade of access road, cut off service utilities and accidents will be more of a concern in population centres and particularly for laying transmission distribution pipelines. However, these can be mitigated without difficulty.

95. Installing the transmission and distribution pipelines may cause minor traffic slow-downs. Part of transmission and distribution pipelines would cross the street causing traffic disturbance. To mitigate the impacts, agreements with the organizations and individuals involved need to be achieved. Also the working time should be arranged in suitable time when traffic density is less crowded. Road deterioration may take place from construction heavy equipment and hauling trucks to transport construction materials.

96. Construction-related accidents may happen to construction workers and/or the local people if construction activities are not well-planned and supervised. Solid waste generation from construction activities and workers as well as human waste is likely to have impacts on peoples’ health and to the environment if not properly disposed of.

97. Low to moderate positive impacts include short-term employment of local population (skilled and unskilled workers) in construction and some increased earnings in micro-enterprises in the vicinities of construction areas. Employment of outside skilled/unskilled labourers may increase social conflicts. To prevent such unwanted incidents, the employment of the local people in the commune should be given the priority to work during the construction period.

4.4 Impacts During Operation

98. The potential adverse impacts at varying magnitudes that can be expected during operation of the completed projects are briefly discussed below.

99. No significant impacts of water supply schemes on air quality are expected. However, noise vibration nuisance may occur, especially in pumping station at the WTP.

100. Access to larger amounts of better quality water will generate larger amounts of wastewater, including: human waste from improved latrines (which generate more wastewater), more wastewater from animals. While waste water is often recycled in gardens, use of gray water (from washing dishes, etc.) or black water (human and animal waste products) can cause adverse environmental impacts if not properly managed.

101. Adverse impacts on the general public may be in terms of delivery of unsafe water to the distribution system that could result from inadequate chlorination and lack of chlorine residual controlling in the distribution system.

102. Improperly installed (or poor quality) water pipes may break, causing leaks and swampy areas, or if not sufficiently pressurized, could allow poor quality ground or surface water to enter the pipelines and contaminate the water supply system.

103. Exposure of workers to an inappropriate use of hazardous and toxic chemicals such as chlorine may cause health problems.



25


104. Adverse impacts on groundwater and nearby wells are likely to result if unsuitable types of latrines (underground pit and pour flush types) are built in flood prone and water logged areas. Similarly proximity of latrines to wells, particularly in shallow groundwater areas can contaminate the ground water. Also the possible leakage and release of gray and black water from septic tank and overflow into drainage canals and into ground water table must at all times be prevented to ensure water quality.

105. The operation of the proposed subcomponents (i.e. water supply, and sanitation facilities) will bring about the following significant socio-economic benefits to the commune:

Access to adequate amount of good quality water by 100% of the population in the service area at a reasonable cost (both for drinking and sanitation);

Improved personal sanitation resulting from hygiene and sanitation behavioral change program (IEC) coupled with latrine facilities, etc;

Better health and environmental sanitation resulting in marked improvement in community health indicators (e.g., reduced frequency of diarrheal and other water related diseases);

Reduced lost work days for adults (e.g., increased income), and lost school days for children (improved educational benefits) due to reduced incidences of diseases;

Saving of time spent for fetching water from distant sources and/or money spent for buying water from vendors; and

Induced socio-economic growth, (promotion of economic growth in various sectors).

5 PROPOSED MITIGATION MEASURES

106. The potential issues, concerns and problems that could arise from the Subproject will be avoided or, mitigated by sufficiently considering in the overall design of subcomponents, from site development planning to the design of structures, selection of equipment, and more importantly, operation and maintenance (O&M) procedures. In order to eliminate or minimize the other negative environmental impacts, various mitigation measures are recommended as appropriate at each stage of implementation of the Subproject for all subcomponents.

107. The proposed measures and monitoring activities to mitigate the identified adverse impacts during construction and operation of subcomponents are standard practices, and are widely used, and can, therefore, be implemented and instituted without difficulty as described in the Environmental Management Plan (EMP) and Environmental Monitoring Plan (EMOP).

108. The EMP plan (Annex 3.1) and EMOP plan (Annex 3.2) provide for the set of mitigation measures and monitoring requirements to be taken during Subproject implementation to avoid, reduce, mitigate, or compensate for adverse environmental impacts. They identify the potential impacts and their locations or occurrences, proposed mitigation measures and identify the responsibilities for implementation of mitigation and environmental quality monitoring activities including the budget requirements.

109. The Environmental Management and Monitoring Plans and budget requirements shall be required to be included in the Subproject bidding and bid documents and budgets, as well as in the Subproject contracts. During Detailed-design stage, responsible parties will need to update EMP and EMOP based on Finalized detail design.



26

Note: - VALUE A: Included in the Contractor's financial bid; - VALUE B: Included in Operation budget of the OU.

136. Based on the location of the Subproject and convenience of transportation, the estimated cost of sample handling, transportation and reporting is taken to be 30% of the total cost of measurements. The Circular no. 45/2010/TTLT- BTC- BTNMT dated 30 March 2010 about Guideline on management of environmental fees will be followed when calculating actual cost of these tasks.

137. Except Estimated cost for Water sampling and analyses which will be included in the Contractors’ financial bids, total cost of other environmental monitoring activities during pre-construction and construction phases (including monitoring the water sampling and analysing) will be included in the CSC’s financial bids. The Environmental Monitoring Cost is estimated based on the Guidelines on cost estimates of consulting services, attached with the Decision No. 957/QD-BXD Norms for investment project management and construction consultant expenditure. Environmental Monitoring Estimated Cost Template is shown in the Annex 3.4.

138. During the O&M phase, Environmental monitoring cost will be taken from the O&M budget of the Operation Unit (OU).

139. The nature of the Subproject and the Subproject locations do not necessitate any specific measurements, such as quality of water in waste receiving water bodies during the construction phase, or noise and vibration level during the implementation of the Subproject. However, if any unexpected impacts arise or are likely to occur, the Environmental Officer will take necessary action in coordination with the PPMU and request the Contractor to carry out measurements.

6 PUBLIC CONSULTATIONS AND INFORMATION DISCLOSURE

6.1 Consultation and Participation Process

140. In this Subproject, one main public meeting and several supplementary public meetings have been held so far. The main public meeting was conducted on 12th February 2012 by PPMU in collaborated with the Dien Yen CPC with guidance and assistance from the PIA Consultant. The venue of the meeting was in the meeting room of Dien Yen commune, Dien Chau district, Nghe An province. This consultation was conducted during the phase of FS review and environmental assessment for Subproject preparation. It was a follow up the public consultation organized by the PPTA consultant in 2009 so its role was to reintroduce the Subproject as well as update information related to the environment and obtain local people’s views on environmental aspects of the Subproject.

141. Attendances at the consultation meeting included some affected people and other concerned stakeholders, namely:

Representatives of the Subproject owner; Representatives of the technical and environmental consultants; Representatives of the local authorities; Representatives of the district and/or communal environmental division;



33


Representatives of the local mass organizations such as Communal Fatherland Front Committee, Communal Women’s Union, Communal Farmers’ Union; and

Representatives of Subproject affected people.

142. The contents addressed in the consultation meeting include:

(i) Collecting information/data about Subproject environmental conditions;

(ii) Presenting the Subproject’s preliminary design, and the proposed Subproject construction site;

(iii) Stating positive impacts of the subproject, the potential adverse impacts that Subproject may cause to the environment and the communities; introducing the effective mitigation measures and environmental management and monitoring plans; and

(iv) Obtaining comments of the participants on the Subproject: consensus on construction of the water supply plant in the area; their support to mitigation measures before, during and after the construction phase; and any suggestions/concerns about the Subproject.

143. Necessary and adequate information was able to be collected during the consultation due to good attitude from participants. Stakeholders and affected persons were eager to contribute opinions as well as time and labour to the subproject. Issues and recommendations raised by the participants are summarized as follows:

(i) Densely populated villages have high demand for clean water and sanitation facilities;

(ii) Representative from affected households supports land acquisition for construction of the Subproject;

(iii) Adverse impacts during construction should be minimized by reducing the duration of pipeline installation and returning road to its initial stage right after pipeline is installed;

(iv) Utilization of big transportation vehicles during construction should be limited to avoid traffic jams occurring on narrow village roads;

(v) The PPMU is requested to ask the Contractor and operator of water supply system to comply strictly with environmental mitigation measures and environmental monitoring plans during construction and operation stages; and

(vi) High consensus on immediate construction of water supply plant and early implementation of all other Subproject’s components.

144. A record of the public consultation meeting minute in Vietnamese and its translation into English are attached in the Annex 4.1.

145. In combination with CBA- IEC activities of the Subprojects, a separate public consultation for the beneficiaries was adopted into some focused group discussions, a tool of community consultation to collect more information from various groups of concerned people including the poor, men and women, and the ethnic minority (if there are ethnic minority people in the Subproject area). A household survey was carried out amongst 5% of the households in Subproject area. The focused group discussions and the household survey were implemented by the CBA- IEC consulting group during February of 2012. Information collected from these meetings and the survey supplements the main



34


public consultation in terms of status of the environment in the Subproject area, sources of water for domestic use, drainage system, sanitation conditions, willingness to connect, demand of water consumption and sanitary behaviour. Detail results of baseline survey are presented in Volume 2 of Nghe An SAR Report.

35


a) All stakeholders should be invited and encouraged to participate in the consultation workshops;

b) The affected people are informed of progress of the Subproject; c) Suggestions from the general public may be sought, when necessary; and d) The PPMUs and, when necessary, People’s Committees (at relevant level) should be

open to contact by the public on matters concerning the progress of the Subprojects, adverse impacts and mitigation measures and environmental monitoring.

Information Disclosure

147. According to ADB’s Safeguard Policy Statement 2009, for projects of Category B, environmental documents that need to be submitted and disclosed on ADB’s website include:

- Draft IEE; - Final IEE; - Updated or corrective IEE during Subproject implementation; and - Environmental monitoring reports.

148. A draft version of IEE was prepared by the PPTA in 2009. According to the Loan Agreement, this IEE document has to be reviewed and updated in compliance with the ADB’s safeguard policy requirements. This updated IEE document will be submitted in the Subproject Appraisal Report for ADB’s approval and disclosed on ADB’s website. All of the IEE reports shall be prepared in both English and Vietnamese. The Vietnamese version of the summary IEE shall be attached in notification boards of Dien Yen commune. Other related documents shall also be attached for reference.

6.3 Grievance Redress Mechanism

149. To continuously receive feedback from Subproject’s beneficiaries, the grievance redress mechanism in accordance with ADB’s guidelines shall be introduced to communities and maintained for the duration of the Subproject. The PPMU will establish a Subproject Site Office (SSO) in the commune where people’s complaints can be lodged. The Subproject Site Office will be used for: (a) construction supervision, including monitoring the Contractor’s compliance to the EMP to ensure the mitigation measures are timely and properly implemented; (b) disclosing all safeguard documents; (c) receiving and responding to the comments/feedbacks from the community.

150. If people affected by the proposed Subproject have any grievances they could raise their concerns/complaints to the Contractors, the CSC, the PPMU and relevant government officials through the grievance redress mechanism set up for the Subproject. Affected people’s complaints should be addressed and resolved by the Contractors, CSC and the PPMU at the SSO within 3 weeks from the date of complaint receipt. An open meeting to the public and affected people might be organized to solve the issues. If the complaints are not resolved within the stipulated time or the complainants disagree with the complaint resolution, they can lodge their complaints to the competent authorities at higher levels such as the concerned CPC at commune level and the Environmental Division of the DPC at district level. Procedures of lodging complaints and resolutions at these levels are in compliance with the GoV’s regulations. All records of the public meetings and how grievances are addressed will be maintained by the CSC and the PPMU at the SSO and the public will have access to these records.

7 FINDINGS AND RECOMMENDATION

151. The screening of the proposed Subproject based on the Rapid Environmental Assessment Checklist have indicated that there will be no impacts to forest land, protected area, mangrove or to any protected species of flora and fauna. Although cultural/historical sites i.e., Dinh Chay Provincial cultural place in hamlet 8 and Phung Chi Kien National historical site in hamlet 1 are located, these important sites will not be encroached or affected by the construction of the WTP and other facilities associated with the water supply system. During the placement of main and distribution pipelines, careful construction and supervision will be ensured to eliminate any potential defacement and destruction of the cultural and historical structures.

152. The potential adverse impacts that are associated with the Subproject would occur during the construction period these are soil erosion, nuisance from dust, noise and vibration including accumulation and disposal solid wastes. These impacts will be minimal and mitigation measures will be implemented to eliminate if not reduced the impacts to the minimum. Moreover, the members of the communes and CPC have an important role in Subproject implementation and operation phases so that they can intervene when necessary or when complaints arise.

153. The operation and maintenance of the water supply will bring benefits that include availability of safe and reliable clean supply of water to the households at a reasonable cost; will improve personal hygiene and public health and sanitation and environmental condition (e.g., reduced frequency of water related diseases; reduced lost work days for adults; increased in school days for children due to reduced incidences of diseases); and will boost the socio-economic growth of the communes. Improvements to drainage system will reduce the exposure to floods and polluted drainage water.

154. All Subproject activities prior to construction, during construction and during operation will be managed as provided in the EMP and the contractor’s compliance and implementation of the mitigation measures shall be monitored. An environmental monitoring plan has been provided to ensure water quality is maintained according to the prevailing Vietnamese standards. Dien Yen DPC also approved the Environmental Protection Commitment in accordance with Vietnamese regulations. The Notice on acceptance of EC registration is attached in Annex 5.

8 CONCLUSIONS

155. The REA Checklist indicated that Subproject site is not

Adjacent to or within protected area; Adjacent to or within buffer zone of protected area; Adjacent to or within wetland; Adjacent to or within mangrove; Adjacent to or within estuarine; Adjacent to or within bay; and Adjacent to or within special area for protecting biodiversity.

156. Although the Phung Chi Kien National historical site and Dinh Chay Provincial cultural place are located within the Subproject area, these two sites are situated in the residential area, separately from the raw water reservoir and WTP area, distantly from the transmission and distribution pipeline system, so they will not be encroached by the Subproject.



37


157. Based on the screening process using the REA Checklist, Subproject has been classified as Category “B” project under the ADB’s Policy on Environmental Assessment Guidelines, 2003 thus, only an IEE report has been prepared. Moreover, due to the nature of the Subproject, location and environmental conditions of the Subproject area, special study or an EIA to comply with the environmental policies of the ADB are not required. Therefore, the IEE can be regarded as the Final Environmental Assessment Report.

158. Under the requirements of the Decree No.29/2011/ND-CP dated 18th April 2011 of the Government of Vietnam, the water supply scheme for the Subproject does not demand an EIA study. However, as required, the Environmental Protection Commitment has been registered and approved by the DPC of Dien Chau District.

2.1 The presentation of PPMU and Consultants

Representative of PPMU: Introduced the objectives and social significance of the Public consultation meeting.

Representative of Design Consultant: Presented the contents of Subproject design.

Representative of Environmental specialists: Displayed positive and negative impacts of the Subproject to the environmental and social communities; and mitigation measures to the negative impacts to the environment and lives of the people in the Subproject area.

Impacts to the environment

Positive impacts

The construction of the water supply system will have positive impacts to the local social-economic development that are significant improvement of people’s living condition in Subproject area, improvement of people’s health and quality of life, diversification of manufacturing production, food processing and other trade services.

After construction is completed, the operation of the Subproject will favour environmental protection activities on soil, water bodies and air as clean and safe water is the first important factor that helps conducting these activities to achieve safe environment for the community.

Clean water supply will support to reduce the incidence of diseases related to using unhygienic water sources. The livestock and poultry development to increase people’s income will not cause much risk on environment and people health because of using clean water. It is more meaningful when the diseases related to unclean water in the Subproject area have been seen statistically at high percentage.

Negative impacts

The Subproject is expected to provide clean water and hygienic sanitation for people. However, it potentially causes some negative impacts to the environment:



Annex 4.1

3


- Transportation of construction materials, soil excavation and filling at WTP area, ditch excavation to install pipelines will cause dust, noise and traffic jam. Although these impacts are not too serious, it is needed to implement preventing measures.

- Demolition waste during construction of works will cause negative impacts to the environment if not managed properly.

- During operation of works, it is required to ensure safety to avoid exploration, fire in case of power problem, pipeline broken that impact on lives, production activities and traffic jam in the Subproject area.

Environment Management Plan

During the Subproject implementation as well as operation of facilities, standards and solution mentioned in Environmental section of FS report need to be followed to minimize negative impacts on the environment. The Environment Management Plan will be carried out in steps similarly as bellows:

2.2 Comments from Local Government and Representatives of Community

Comments from Local Government:

The Subproject brings to the people of Dien Yen Commune great, practical and long-term benefits. Implementation of the Subproject has impacts on the environment but it’s not significant and can be mitigated. As for the impacts on the population and community, the total positive impact is greater than the total negative impact which can be mitigated by the measures stipulated in the Feasibility Study Report. The problem is that the obligation of monitoring the mitigation measure must be addressed. The Dien Yen Authorized Agencies commit to comply with the requirements stated in the Feasibility Study Report, encourage people to overcome difficulties and agree on Subproject implementation.

Comments from Representatives of Community:

Representative of Vietnamese Fatherland Front Committee of Dien Yen Commune: The Subproject brings practical benefits to the people, improves the living conditions, reduce diseases related to polluted water and environment. Although the implementation of Subproject causes impacts on the environment of the local area such as noise of construction machinery, dust, excavation of road which obstructs traffic, it will not affect significantly on the people’s lives, and the impacts can be reduced by the people’s efforts and mitigation measures as provided in the Feasibility Study Report. Therefore, the Vietnamese Fatherland Front Committee of Dien Yen Commune agreed on Subproject implementation.

Representatives of Women’s Union of Dien Yen Commune: After listening to the Feasibility Study Report presented by the Consultant’s Representative, Representatives of Women’s Union of Tay Giang Commune felt very excited because the expectation of Dien Yen Commune’s People, is going to become true, especially for the women who are directly affected the most due to not having clean water and



Annex 4.1

hygienic latrines. During implementation of Subproject, in spite of some impact on the environment and daily activities of the people, for the benefit of every people, they must be encouraged to overcome difficulties, meanwhile there will be mitigation measures as provided in the Feasibility Study Report. Therefore, the Women’s Union of Dien Yen Commune agrees on early implementation of Subproject.

Representative of Farmer Association of Dien Yen Commune: Highly agreeing with opinions of the Government and Unions, the Commune’s Farmer Association hoped that the Subproject will be implemented soon so that the people will soon be benefited by the project and in its assigned tasks, the Association will encourage every member to contribute to construction and operation management of the facilities, so that the facilities for effective operation and long term benefit. For negative impacts on the community during implementation of Subproject, the Association will mobilize the people to cooperate with concerned parties to overcome and reduce such negative impacts.

Representative of Health Center of Dien Yen Commune: In recent years, due to water and environment pollution, the diseases related to domestic water and sanitation, , especially fatal diseases tend to increase. The water supply & sanitation Subproject is necessary to the people of Dien Yen Commune. During Subproject implementation, there will be negative impacts on the environment and people’s lives. However, with the measures provided in the Feasibility Study Report and if they’re strictly implemented by the concerned parties and with the effort of the people to overcome them, the impacts can be mitigated. We are kindly request to implement the Subproject soon.

Representatives of beneficiaries

Mr. Mai Trong Chau, from hamlet 16, Dien Yen commune: Our hamlet is very crowded with limited residential land. Clean water and sanitary facilities are an urgent demand. If the construction team does not implement a reasonable construction option, traffic congestion will occur, obstructing travelling and polluting the environment. Therefore, big trucks carrying construction materials into the hamlet are not recommended and backfilling roads must be done right after installation of pipes for convenience of the residents.

Mr. Pham Hong Long, from hamlet 9, Dien Yen commune: In our hamlet, most of the households have registered to participate in connection to pipeline and construction of latrines. We understand that during construction, we will encounter some difficulties such as congestions on lanes and roads, gardens excavated for pipe installation, obstructed travelling, noise and dust. Therefore, we recommend that construction should be done in a timely and neat manner, and one route should be completed before starting construction of a new route.

Mr. Nguyen Van Sau, from hamlet 16, Dien Yen commune: We are lending the CPC’s managed land for cultivating and fishing and now CPC plan to acquisition this land for construction of the water supply scheme. I really support the Subproject as it is a public project bringing benefits of health improvement to all of the local residents. I agree to allocate land to the Subproject. I recommend that PPMU and local agencies to give us the suitable land acquisition as our right could have. I respect to early implementation of Subproject.

Mr. Tran Van Truong, from hamlet 5, Dien Yen commune: My house is at the head of the hamlet that main pipelines certainly pass through. My house’s access lane might be in excavation during pipeline installation that will cause obstructing travelling. My family will try to overcome difficulties and create favourable conditions for Subproject implementation hopping that it soon be put into operation for the benefit of all the people in the commune. I recommend that the construction should be done timely, do not last too much long time causing inconvenient for people life.

Mr. Tran Dinh Hoa, from hamlet 16, Dien Yen commune: My family is poor household and getting economic difficulties. However, we have registered to participate in connection to Subproject program to improve our family water using and sanitation. This is our best chance. I am willing to conduct commitments specified for the Subproject.

Representative of Subproject Owner – PPMU:

Would like to say thank for the people participation, contribution to Subproject. The conclusions could be stated as the following:

Regarding the environment aspect, Subproject will bring benefits to people in the commune but its implementation will causing some negative impacts to environment and affecting daily people life such as losing of cultivation land, obstructing traffic from road excavation for pipelines installation, noise and dust. But the impacts could be limited and reduced by the particularly mitigation measures and by the consensus of the concerned parties to the Subproject. Local people and mass organizations opinions showed that the Water supply and Sanitation Subproject for Dien Yen commune is very necessary and long-term advantaged to the people. PPMU will manage to implement the Subproject soon.

Regarding affected households and units, they present their acceptance of the negative impacts that Subproject may cause and willingness to actively collaborate with other stakeholders to address and limit negative impacts for ensuring daily people activities. PPMU and local governments are requested to ensure the rights of affected households complying with GoV’s provisions and early implement the Subproject so that all the people in the commune could get Subproject benefits soon.

All the parties were unanimous in the issues mentioned above.
