1 INTRODUCTION

1.1 Project Background

1. 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 percent of the rural population will (i) have access to clean water with a minimum volume of 80 liters per capita per day; (ii) use hygienic latrines; and (iii) practice proper personal hygiene.

2. 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 Subprojects, divided into 3 batches with 6-9 subprojects of each scheduled to be completed by 31 December 2016. 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.

3. The Water Supply and Sanitation Subproject (WSSS) for Tay Giang, Tay Thuan Communes, Tay Son District, Binh Dinh Province have been selected as one of six pilot subprojects of the Central Regions Rural Water Supply and Sanitation Sector Project (CRRWSSSP) to be implemented under the Loan Agreement No. 2609 – VIE (SF) between the Socialist Republic of Vietnam (GoV) and the Asian Development Bank (ADB).

4. The pilot subproject of Binh Dinh province includes two components: Water Supply System to construct a new WTP, with capacity of 1500m3/day and a pipeline network to provide clean and safe water to four hamlets in Tay Giang commune and two hamlets in Tay Thuan commune; and Environmental Sanitation to improve sanitation condition for 1,663 households, and public works and also raise awareness of environmental protection of people living in the beneficiary area. The pilot subproject, after completion, is expected to benefit about 14,535 persons by 2020 in both communes.

1.2 Purpose and Extent of the Updated IEE Report

5. The updated IEE report document will be submitted and included among the documents for review required for the Subproject Appraisal Report (SAR) of Binh Dinh Pilot Water Supply and Sanitation Subproject.

6. Updating of IEE report involves three main activities: (i) review of the subproject documents including the engineering design and the Feasibility Study (FS); (ii) consultations, site visit and field validation of data and information on the existing environmental conditions relating to the identified potential impacts, issues and concerns; and (iii) revisions and subsequently finalization of the updates to the Initial Environmental Examination (IEE) report.

2 DESCRIPTION OF THE SUBPROJECT

2.1 Type of Subproject

13. 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 on each Project Province. Binh Dinh 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 the Subproject

14. The screening and the environmental categorization of the Binh Dinh Water Supply and Sanitation Subproject (WSSS) was performed using the sector-specific Rapid Environmental Assessment (REA) Checklist of ADB. As the REA Checklist has indicated no significant impacts to the physical environment, forests or protected areas or to the cultural and historical sites located within the Binh Dinh Subproject area, the proposed water supply scheme therefore is classified as Category B under the ADB’s 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).

15. Pursuant to the Decree No. 29/2011/ND-CP dated 18th April, 2011 on Strategic Environmental Assessment (SEA), Environmental impact assessment (EIA) and Environmental Protection Commitment (EC), environmental assessment requirements are determined based on the type, scale and capacity of the proposed project. The Decree classified projects into 3 types of projects i.e., projects listed in Annex 1 are required to prepare a SEA; Annex 2 list of projects are required to conduct and prepare an EIA report and Annex 3 projects are subjected to an EIA to be appraised and approved by the MoNRE.

16. Projects not listed in Appendices 1, 2 and 3 are required to apply and prepare an Environmental Protection Commitment (EC) to be submitted for registration and acceptance from the concerned District Peoples’ Committee (DPC). The EC document shall conform to the guidelines and requirements of the Circular No. 26/2011/TT-BTNMT dated 18th July, 2011 by MoNRE.

17. The Binh Dinh water supply scheme is not listed in any category of the Annex 1, 2 and 3 of the Decree because water requirement for the subproject will only be a volume of 1,500 m3/day to be sourced from the ground aquifer. Nonetheless, under the same Decree, it is required to apply and prepare an Environmental Protection Commitment



5


(EC). The preparation of the EC document needs to conform to the guidelines of the Circular No. 26/2011/TT-BTNMT. The EC document was submitted for registration to the concerned District People’s Committee (DPC).

2.3 Need of the Subproject

18. Historical data have shown that groundwater in the existing residential areas along the National Road 19 (Ta Giang and Thuong Giang hamlets of Tay Giang commune; Thuong Son and Trung Son hamlets of Tay Thuan communes), are under fluorosis contamination, grease pollution and high level of hardness. Local people are not only suffering from periodontal disease and other waterborne diseases but also, facing shortages of water in dry season. They have to either carry water from the surrounding area (near Con river and other areas) or purchase water at a very high price of 37,500 VND/m3 from a vendor in Tay Giang commune. As a result, people living in the subproject area have so long wished for the Government’s interest and investment in clean water supply projects to meet their daily needs. Promotion of sanitation practices and facilities also helps reducing waterborne diseases.

19. The success of the project will not only help the communities of six rural hamlets of the two communes solve the problems of clean water , but also improve their lives, protect environment and reduce the use of poor quality water, untreated water, and insufficient water as well as decrease the risk of illness due to the poor water quality.

2.4 Subproject Location

20. Binh Dinh is one of six (6) Provinces in the central coastal region of Viet Nam which has been selected to the Central Regions Rural Water Supply and Sanitation Sector Project (CRRWSSSP). It is shown in the Figure 1 Location map of six Project Provinces of the central coastal region of Vietnam.

21. Tay Son District is located in the Southwestern part of Binh Dinh Province. It is 61 km from Quy Nhon City, as shown in Figure 2. Tay Giang and Tay Thuan communes are two midland communes in Tay Son district’s, 12-20 km far from the district center.

2.5 Subproject Components

2.5.1 Piped Water Supply System

26. With capacity of 1,500 m3/ day, the piped water supply system provides transmission and distribution pipeline system of approximately 54,300 m length. It will consist of: (i) a raw water source from the drilled well; (ii) treatment plant; (iii) pumping station; (vi) transmission main; (v) distribution system; and (vi) house connections or communal taps, with water meters.

27. Operational and sustainable piped water supply system will have to:(i) provide water continuously at quantities not lower than 80 liters per capita per day;1 (ii) tap water will be cleaned 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;2 (iv) the water tariff will cover operation, maintenance and depreciation costs; (v) the water bill per household, based on 80 liters per capita per day, will be less than 3% of average monthly income.

Raw Water Source (Drilled Wells)

28. According to the result of Ground Water Quantity and Quality of Exploration Report of the Southern Water Resource Planning and Investigation Union dated January, 2009, the area located in the bank of the Con river’s (near the Head office of Tay Giang People’s Committee) in Ta Giang village has three following aquifers:

The intergranular aquifer of Holocen sediment (Q2) The intergranular aquifer of Pleistocen, middle and upper (Q12-3) Porous complex aquifer of Mezozoi-Pelozoi (MZ-PZ).

29. Of which, the intergranular aquifer of Pleistocene, middle and upper (Q12-3) has average distribution area with average depth of the aquifer being 19.80 m, including sand, pebbles and gravel. This area has a relatively large deposit of underground water with good quality. Thus, it can meet the water demand of the local people.

30. The result of the exploration survey of three drilled wells with the depth of 4-10m, namely G1, G2, G3, is shown that each of them can be exploited at the maximum capacity of 40 m3 per hour. The water sampling and analyses for these wells has been conducted and the result is shown in Table 1.

1 The RWSS strategy prescribes a minimum of 60 liters per capita per day (lcpd). For piped water supply schemes with

house connections, a rate of 80 lcpd is a more realistic design criteria, considering easy access to water supplies. This is supported by the World Bank's Red River Delta Water Supply Project, where the first batch of subprojects were designed for 60 lcpd which proved to be not enough. The next batches adopted 80 lcpd as design capacity. Source: Project Administration Memorandum, October 2011, Page 1.

31. As shown above, the water quality analyses that taken from drill-wells (G1 and G3) have indicated that the contents of Manganese (Mn) and Nitrate (NO-3) exceeded the Vietnamese standards indicated in QCVN 09:2008/BTNMT - National technical regulation on Ground water quality. The unusually high content of Nitrate needs to be carefully checked in the next water analysis. Mn with excessive content can be easily cleaned during the water treatment process. For COD (KMnO4), the PPMU is recommended testing this parameter during the detailed design. This parameter presents the amount of organic compounds in water. It should be less than value of 4 for ground water so that the water is not polluted and suitable for domestic and drinking purposes.

32. According to hydraulic investigation results, the hollow aquifer of the middle-late Pleistocene sediments was chosen to be the abstraction layer to supply water for domestic usage locally. The aquifer is recharged by rain water and mostly by water from Con river. Water extracted from the test wells during the hydraulic investigation seemed to be clear with no taste or odor . Water abstracted from dug and drilled residential wells nearby the well field has not been found contaminated with oil or fluoride. Experience of abstracting water from ground aquifer along Con river has shown good quality of water. In addition, the water treatment technology package for the subproject is designed to address the site specific water quality standards to meet the 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)).

33. Based on the result of the water exploration, the ground water to be exploited in the left bank of the Con river’s as shown in Photo 1 Location of the bored holes on the bank of the Con river below will be selected as the raw water source to supply to the Water Treatment Plant of Tay Giang and Tay Thuan communes. Since the drawing capacity of the Subproject is about 31 m3/hour/ well (two wells on duty and one well on standby), which produces a volume of 1,500 m3/ day, the Binh Dinh Province People’s Committee will pose for approval of the water supply after the Department of Natural Resource and Environment DoNRE’s assessment of the proposed wells. The hydraulic calculation showed that the amount of water needed for the WTP is enough even in the worst case scenario.

34. Technology scheme shall be 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, ground water from drilled wells will be pumped to the Water Treatment Plan situated on the top of the hill beside. After treatment, the clean water will go through the transmission and distribution pipeline system to the house connections by gravity on low-load hours, taking advantage of largely different height between the plant and the residential area. On peaking hours, a pressure pump can be used.

35. The scheme is shown in Figure 4.

Figure 4 Water treatment diagram.

36. This technology has been applied in many places in Binh Dinh province and other

provinces of the country and shown that the technology has high effects and low investment costs with easy operation and meets management requirement of the Subproject Owner. Sludge arising during the settling and rinsing process will be stored in settling basin, then periodically scooped out and disposed in the landfill as specified; the overflow water from settling basin will be discharged into the drainage system of the treatment plant.

Water Treatment Plant

37. The Water Treatment Plant (WTP) site is an agriculture area which belongs to the Tay Giang Commune People’s Committee (see Photo 2 below). The WTP will be located on an elevated hill, near Highway No. 19 of Ta Giang village, Tay Giang commune. The drilled wells are located approximately 600-800 meters from WTP site. The

42. In promoting construction of latrines among HHs and public areas, 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 project. This circular indicates 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 greywater 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.

43. According to the Project Administration Memorandum (PAM), Project will support double vault composting and pour flush latrines for household use. Based on the



16


data/information of the baseline survey (CBA-IEC), most households who have been consulted prefer to have septic tank latrine.

2.6 Subproject Schedule for Implementation

44. The Subproject Implementation Schedule is estimated to cover a period from 1 October 2011 until the Overall Project Completion on 31 December 2016 . At the pre-construction phase, after selection of the successful Design and Build Contractor (Contractor) through the bidding procedure, the Contractor shall prepare the Detailed design, and construct the water supply system based on the approved engineering plans.

3 DESCRIPTION OF THE ENVIRONMENT

3.1 Physical and Ecological Resources

48. Binh Dinh is a coastal province in the southern part of the Central Region of Vietnam with a total land area of 6,039 km2. It borders Quang Ngai Province in the north, Phu Yen Province in the south, Gia Lai Province in the west and South China Sea in the east. The Eastern border is the coastal line with the length of 143km.

49. Tay Giang and Tay Thuan communes belong to Tay Son District in Binh Dinh Province. They are located about 12-20km far from the distinct center, along National Road No. 19, which is the main commercial road from Binh Dinh province to the Central Highland provinces.

Climate

50. Binh Dinh has a humid tropical climate with prevalent winds. Winter is slightly cool with winds mainly from the southwestern or southern direction. Summer temperatures are fair with winds from the east and southeast. Large storms usually occur in the rainy season, particularly in October.

51. Binh Dinh is a coastal province in the southern part of the Central Region of Vietnam with a total land area of 6,039 km2. It borders Quang Ngai Province in the north, Phu Yen Province in the south, Gia Lai Province in the west and South China Sea in the east. The Eastern border is the coastal line with the length of 143km.

52. Rainy season is from May to December. The annual average precipitation is around 2000 mm to 3000 mm with the highest precipitation being in October and November. Dry season is from January to April and usually causes drought and shortage of water for farming work and living conditions. In May and June, if average rainfall amounts are more than 100mmm, sub-chronic floods often occur. As the dry season lasts for 4 months, rain water does not guarantee a reliable source of water.

53. As a coastal province with 124km of coastline and 24 communes located along the

coast, Binh Dinh is under the zone of substantial influence of climate change. Storms, draughts and sea water intrusion have become more serious in the recent years affecting local people’s daily and economic activities (according to http://www.pclb-tkcnbinhdinh.gov.vn/ and http://www.dostbinhdinh.org.vn/). Due to more severe natural catastrophes, water resources are subject to more unstable quantity and quality.

54. The planned exploitable capacity of the water treatment plant is 2000 m3/day, which is a small number compared to the potential exploitable capacity of the extraction aquifer of 19,590 m3/day. This aquifer is recharged by the rainfall and water from Con River. As rainfall amounts in dry season and rainy season vary among years, the water level of Con River varies accordingly, affecting the recharge rate of the aquifer. Scientific research predicts the greatest decrease of water flows by 30% by 2070 due to the increase of 4.5 oC of temperatures (http://stnmt.binhdinh.gov.vn/newsdetail.php?newsid=262&id=39). In this case, the extraction aquifer with the current potential exploitable capacity of 19,590 m3/day could be less , but would still sustain abstraction of 2000 m3/day exploitation and most likely even higher needs in the future.

Air Quality and Noise

55. The subproject area is located along a road, so it is affected by dust and noise from traffic on the road.

Topography

56. Topography has high slope from West to East, with the western side bounded by the toe of the Truong Son mountain range. There are 30 different types of soil in the province with 71,000 hectares of silt. Approximately 117,000 hectares of land are used for agriculture; 202,700 hectares is forestry land, and 154,400 hectares is natural rain forest. There are more than 195,000 hectares of marginal land, potentially good for either agriculture or forestry development.

57. The communes have very complex terrain, which consists of high mountains, hills and flat plains, divided by large and small rivers and streams in the region, flowing from the northwest to the southeast. Elevations range from 400m to 800m, and typical slope is about 25 degree with high rate of erosion during rainy season.

Geology and Soils

58. Generally, the location for construction of the water treatment plant has a relatively good geological condition. The layer 1 m under the natural ground is weathered rocks, mixed soils and gravel with hard and tightly texture. Base-load capacity is more than 2 kg/cm2.

Water Resources

Surface water

59. The sub-project area has a well-developed network of rivers and streams, mainly from two river systems flowing from the North-west to the South-east into Con River and draining to the Southeast. The rivers and streams in the region are:

Con river is derived from the high mountains in the north flowing through the central region following Northwest – Southeast direction, length of the river flowing through the sub project area is about 8km, of which 3 km belonging to Tay Thuan commune in the North. River width is from 25m to 50m. The river has flow throughout the year, and is not affected by ocean tides.

Cai spring carries the flow from a group of springs originating in the high mountains which create northeastern streams and mango garden springs in the



19


South. It flows from west to east and enters the central area. Length of the river flowing through the sub project area is about 7km. River width is from 15m to 25m. The river flows all year round.

Ba La spring is a merge of Dong Tre streams originating from the high mountains in the west and the system streams under mountains Hon Giac, and Hon Dung. It flows from the Southwest to Northeast and enters Con River in the central region. In the dry season, the water flow is not significant.

Ground water

60. The subproject area has a very limited ground water reserve. Ground water is extracted from dug and drilled wells. It is the main source of water for domestic use but many of the wells abstracting water from shallow aquifers are contaminated with fluorides and oil.

61. In the subproject area, along Highway 19 within the 2 communes, shallow well-water is polluted by petroleum spill during the war. Groundwater analysis of drilled wells and dug wells in some parts of the two communes shows that fluorides and Fe2+ exceed the standards, causing black teeth diseases (see Photo 4). Photo 4 shows signs of dental fluorosis due to high concentration of fluoride in shallow ground water.

62. In these parts of the two communes, groundwater from shallow wells is not qualified for domestic use. However, according to water quality analysis at the subproject site, good quality of deep ground water can be found along a side of Con river (see Table 1: Result of raw water sample analysis form drilled wells).

Forests, Protected Areas and Endangered Species

63. Tay Giang and Tay Thuan communes is the habitat of some wild species such as deer, cow, rabbit, pig, python, snake and some bird species. However, based on consultation with provincial authorities, as well as review of DONRE/MONRE information, there are no known rare or endangered species found anywhere in the subproject area.

Coastal Resources

64. With a 134km coastline and large territorial sea area of 2,500km2 together with an exclusive economic area of 40,000km2, Binh Dinh has abundant sea product resources with high economic value such as: mackerel, yellow fin tuna, shrimp, squid, salangane's nests, lobster and emperor crab, etc.

65. Subproject area is not located along the coastal line, thus it will have no impact on coastal resources.



20


3.2 Economic Development

Industries

66. Subproject area is not an industrialized zone with a few industrial activities. There is a sugar production factory and a brick factory in Tay Giang commune. In the future, two industrial zones will be developed, one in Thuong Giang 2 hamlet and the other in Thuong Son hamlet.

Agriculture development

67. In the subproject area, agriculture is main economic activity in Tay Thuan. Tay Giang commune has more diversified source of income. The agricultural sector in the two communes encompasses cultivation, husbandry, aquaculture and forestry.

Infrastructure Facilities

68. At the sub-project area, the main water supply source is groundwater from shallow or drilled wells. Tay Giang commune has 54 drilled wells, and 1814 shallow wells exploiting ground water at shallow level. Almost all wells in the commune have low water quality. Especially, the water source from two villages Ta Giang and Thuong Giang villages is contaminated with fluoride and oil spills from the US- Vietnam war. Tay Thuan commune has 32 drilled wells, and 1382 shallow wells exploiting ground water at shallow level. Wells in Tay Thuan commune also produce low water quality. Especially, water source from two villages Thuong Son and Trung Son is affected by oil spills. Diseases mainly related to water, environmental sanitation, and personal hygiene, are teeth inflammation, black and damaged teeth; and all kinds of fevers.

69. In Tay Giang commune, there is a water treatment facility that utilizes and treats water abstracted from Con river by simple sand filtering technology. Water is sold at a price of 37.500 dong/ m3, which is too high and above affordability of many local people.

70. The sub-project area has no rainwater drainage system and sewage system. Rainwater flows over the streets then to rivers and springs close by. Wastewater from households is directly discharged into the environment. In some areas, such as markets and houses along the road, wastewater flows directly to the road, at some places that might lead to environmental pollution.

71. Solid waste in the subproject area is not disposed into sanitary landfills. Household solid waste is sorted at the source. A portion is sold to scavengers and the rest is disposed to surrounding environment.

Transportation

72. The subproject has very convenient transportation because both communes are located mostly along National Road No. 19. Tay Giang commune allocates 1.72% of the total natural land area for traffic roads. Tay Thuan commune owns 76.90 km length of roads. Most of the inter-communal roads in both communes are concreted while inter-hamlet roads and lanes are mostly non- graded or graded soil roads.



21


Land Use

73. Binh Dinh province topography includes hills and mountains, delta and sea with 11 land groups and 30 different land types, in which 71,000 ha of alluvial soil, 117,000 ha of agriculture soil and 202,700 ha of forest soil with available forest.

74. Tay Giang commune has a natural area of 7,352 hectares, including production land of 1,740 hectares. Total natural area of the four hamlets in Tay Giang subproject area is 3,020 ha including 1,220 ha of production land.

75. Tay Thuan commune has a natural area of 7,751 hectares. The four hamlets in the subproject area possess a natural area of 5,648 ha and 3,217 ha of production land.

Power Source and Transmission

76. The national postal and telecommunication network has been covered most of the inhabited areas of the province. The subproject areas have electricity, postal and telecommunication stations to serve demands of local communities.

3.3 Social and Cultural Resources

Population and Communities

77. In the subproject area: Tay Giang has a population of approximately 13,070 people (2010) in which females are 6,845, and the number of households is 3,004 households. The number of poor households is 361 accounting for 12.03 % of the total households. The rate of natural population growth is 1.1% (2010). Tay Giang is divided into 06 villages and Dong Pho town, which is relatively developed. Kinh is the only ethnic group.

78. Tay Thuan commune is divided into 4 villages with 1,709 households and 7304 inhabitants; Thuong Son village has 681 households, 2,561 inhabitants; Trung Son village has 295 households with 1,163 people. Rate of natural population growth is 1.1%. The number of poor households accounts for 18%. Kinh is a main ethnic group.

79. People in working age makes up 45% of the total population. The average income in Tay Thuan and Tay Giang communes is approximately 1.2-1.4 million dong/ person/ month.

Health Facilities

80. In Tay Giang commune, there are 2 clinics with 8 beds while Tay Thuan commune has 1 clinic with 2 beds. The local clinic centers have played a sufficient role in providing daily health care for the local residents as well as running anti- epidemic diseases campaigns. For more severe diseases, local people may go to two general hospitals in Quy Nhon namely Hospital and City Hospital and two other hospitals either newly developed or being developed: Bong Son Hospital and Tay Son Hospital respectively. There is also one convalescence centre situated at Phu Cat District.



22


Education Facilities

81. Specification and diversification of education and training forms have been developed to meet demands of learners and human resource development. There are all levels of education from kindergarten to high school in the subproject area. At the kindergarten level, Tay Giang commune has 3 kindergarten locations but is insufficient with 8 class rooms while Tay Thuan commune has 2 kindergarten locations. Most of the children of kindergarten age go to the schools which do not have adequate sanitation and clean water supply facilities. Tay Giang and Tay Thuan have 3 and 1 primary schools respectively but the schools are not supplied with sanitary toilets and piped water. There are also two secondary schools and one high school in the communes meeting educational demand of local students.

Cultural/ Historic Sites

82. In Tay Giang subproject area, there are no cultural or historic places. In Tay Thuan commune, two cultural/ historic sites are located within subproject coverage. They are a Caodaist oratory in Trung Son hamlet and a Memorial of 3 Golden Star division located near National Road No.19 of Thuong Son and Mieu Tu hamlets (see Photo 3 Cultural/Historic Sites below)

4 SCREENING OF POTENTIAL ENVIRONMENTAL IMPACTS

83. 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:



24


Strategic Projects and Master Plans subject to Strategic Environmental Assessment (SEA) (Annex I)

Projects subject to Environmental Impact Assessment (EIA) (Annex 2) Projects subjected to EIA to be appraised and approved by the Ministry of Natural

Resources and Environment (MONRE) (Annex 3). Projects not listed in Annex 1, 2 and 3 will be required to prepare and register an

Environmental Protection Commitment (EC) to the District People Committee.

84. The daily water supply requirement of the Binh Dinh pilot subproject is 1,500m3 and will be drawn from ground water wells. Based on the above mentioned Decree, the scale or magnitude of the proposed subproject water supply scheme is small and not listed in Annex 1, 2 and 3 of the Decree. Nonetheless, the subproject is required to apply and submit an Environmental Protection Commitment to the concerned District Peoples Commune for registration and approval. Under the ADB’s REA Checklist the Binh Dinh Subproject is classified as Category B and requires an IEE report.

85. 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, etc.

4.1 Impacts due to Location

Water Supply Structures and Facilities

86. The Subproject water supply system will include installation and construction of structures and facilities such as: 3 well pumping stations, water treatment plant, oxidization tower, settling basin, rapid sand filter, the reservoir, raw water pipeline, clean water basin, chemical and storage house, drying yard for sediment, administrative house, housing of staffs, pipeline system, and waste water drainage system. It will also provide construction of two guard houses, entrance gate, fence, garage, and access road to the water treatment plant.

87. The proposed sites for the installation of boreholes and construction WTP and associated structures will be located in an agricultural land presently cultivated for peanut production. The total permanent land loss is 1,900 m2 including land allocated for the WTP, access road to the WTP and the 03 boreholes. The total temporary acquired land for pipelines and works on system is 35,000 m2.

88. Within the proposed sites for the construction and installation of the buildings, structures and facilities no forest land, heritage site will be encroached by the proposed subproject, no environmentally sensitive sites and 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 as there are none of them. Further, there will be no impacts on cultural use of lands by indigenous minorities or impairment of aesthetics in the environment will not occur.

89. Two cultural and historical sites namely: the Caodaist Oratory in Trung Son hamlet and Three Golden Star Division in Thuong Son and Mieu Tu hamlet will be given due



25


attention in the final engineering design of the subproject in order to avoid encroachment and impairment of the sites and its structures.

90. 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 adequate drainage around the structure.

91. Selected location for WTP and clean water storage tank is on a hill, 20-30 m higher than the residential area adjacent to the Highway 19, in Ta Giang village of Tay Giang commune. This agricultural land belongs to management of Tay Giang People's Committee. An access road will be used with manual labor for haulage during construction on the hill where there are some small trees, and vegetation coverage is thin. A temporary disruption of the land use is expected during the construction and laying of pipe-lines.

92. The total land recovery required for subproject facilities is 35,000 m2 temporarily and 1,900 m2 permanently (for the WTP area, access road to the WTP and the well field). There are 148 HHs and 2 Commune People’s Committees are affected by land acquisition. Such land recovery and a resettlement plan have been prepared according to ADB and GoV resettlement policies to address the affected parties.

Water Sources

93. Site selection for water abstraction was based on the availability of adequate quantity of good quality treatable water sources. Subproject follows relevant guidelines/regulations and policies of the GoV and MoNRE at the national level or DoNRE at District level.

94. Decree 149/ND-CP, dated 27 July 2004, on issues related to certification for exploratory drilling, exploitation and using water recourses and discharge was followed to obtain the permission for water abstraction. Potential sources have been tested for water quality to ensure that the source water can be feasibly 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 each 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 environmental and health adverse impacts.

95. Hydrological data supports the availability of adequate water resources throughout the year in the selected source to meet the full demand including that of dry season demand over the long term. The laboratory analysis of water quality from drilled wells have indicated high concentrations of nitrate and manganese that exceeds the water quality standards of Vietnam, other water quality parameters analyzed have passed the water quality standards of Vietnam.

Sanitary Latrine Construction

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



26


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

98. Also, all latrines for households and public areas will 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 protection of the environment and to safeguard peoples’ health.

4.2 Impacts Related to Design

99. The potential impacts issues and concerns related to the design that would bring about increased costs in O&M, and possible adverse impacts on the environment and public health.

Water Supply Facilities

100. Potential impacts include:

Unsatisfactory raw water quality, the pollutants of which could not be removed using available treatment processes, e.g. high iron content in ground water and possible pesticide residues and high content of nitrogen and phosphate content form chemical fertilizer;

Inadequate design of facilities for receiving, storing, handling chlorine cylinders so that, with improper O&M, workers (and neighbors) will suffer from toxicity from chlorine gas escaping to the environment;

Absence of disposal facility for sludge from water treatment facilities; Inadequate buffer zones around pumping stations and treatment plants as may be

necessary to mitigate noise and other possible nuisances to neighboring properties (and/or communities) and for protecting these facilities from damage by outsiders;

Increase of greywater 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.

Sanitary Latrines

101. This is the midland region and people have been gradually transferred the use of septic tank replacing the latrines with two compartments and pour flush latrines. The subproject will support building substructures of septic tank latrines for subproject households. The subproject will support the construction of new septic latrines and self-absorbed domestic wastewater collection pits for households without toilets in both communes.

4.3 Impacts during Construction

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



27


Air Quality

103. 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 and relatively will not have greater impacts as compared to the construction of other required structures or facilities for the subproject. The same significance of impact is expected in public areas and road sides.

Physical Environment

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

105. 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.

106. 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.

Biological Environment

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

108. Except the WTP and the clean water reservoir located on the hill with scattered and commune plant species, low or negligible impact on local flora and fauna are expected. The cut-down and compensated trees were 183 fruit trees and 172 perennial trees and no rare or endangered species occur in the subproject area. The boreholes are sited on agricultural land, and requires very little land for permanent structures. The largest extent of land required for the WTP is a commune’s land. The main transmission pipes will be located within the right of way of the existing roads. No land degradation will happen within the Subproject area.



28


Socio-Economic Environment

109. Little or no impact is anticipated on land use since the sites are located on agricultural and public land area. Temporary agricultural land acquisition is about 12,718 m2. The permanent land acquisition from residential area is only 180 m2.

110. 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.

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

112. Installing the transmission and distribution pipelines may cause minor traffic slow-downs. Some of transport pipe and distribution of water line would cross the street causing traffic disturbance. To mitigate the impact the agreement with the organizations and individuals involved needs 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.

113. 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.

114. 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 laborers 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

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

116. 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.

117. 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 greywater (from washing dishes, etc.) or black water (human and animal waste products) can cause adverse environmental impacts if not properly managed.



29


118. Adverse impacts on the general public may be in terms of delivery of unsafe water to the distribution system that could result from inadequate chlorine residual in the distribution system. For the operator, leaking distribution system generate non-revenue water.

119. Improperly installed (or poor quality) water pipes may break, causing leaks and swampy areas. If the pipeline is leaked and not sufficiently pressurized, poor quality ground or surface water may enter the pipelines and contaminate the water supply system.

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

121. 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 grey 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.

122. 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, 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

123. The potential issues, concerns and problems that could arise from the subprojects 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 project for all subcomponents.

124. The proposed measures to mitigate the identified adverse impacts during construction and operation of subcomponents are standard practices, and are widely used and can be provided and instituted without difficulty as described in the Environmental Management Plan and Monitoring Plan.



30


125. The Environmental Management Plan (EMP) and Monitoring Plan provide the set of

Any issues that call for further monitoring activities or other investigation will be raised by the CPMU in the quarterly progress reports and discussed at review missions.

150. These quarterly reports and data should be submitted within 15 days of the end of each quarter. The report will be based on field inspection, investigation, consultation and information given in the monitoring report.

5.7 Budget for Environmental Monitoring

151. The cost of environmental monitoring will be that required for the remuneration of staff involved in EMP activities and their traveling expenses as well as any direct cost for monitoring activities. Cost Estimates for Environmental Monitoring is given in Table 6 Estimated Cost of . The cost estimate excludes salaries of PPMU/ EO staff and some costs incurred by the Contractor during construction as they are difficult to separate from the construction unit cost.

152. Subproject Construction phase will last 12 months. Subproject Operation and Maintenance (O&M) phase is expected to start in the third quarter of 2014, and Project completion will come in the end of 2016. In this Table, it is calculated for Subproject O&M phase Environmental monitoring of 2,5 years. This estimation is based on quotations from laboratories in Binh Dinh and where the quotation is not available, the estimated cost is taken from Circular no. 232/2009 TT- BTC dated 9th December, 2009 of Ministry of Finance.

153. 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. Total cost of environmental monitoring during preconstruction and construction phase will be included in the Contractor’ financial bids. Environmental monitoring cost in the O&M phase will be taken from the O&M budget of the subproject.

154. The nature of the Subproject and the Subproject locations do not necessitate any specific measurements, such as vibration level or quality of water in waste receiving water bodies, during the construction phase. However, if any unexpected impact arises 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

155. To fulfill safeguard requirements of a ADB’s class B project as well as Decision No. 48/2008/QD-TTg (General Guideline on preparing FS report for ODA projects), the PIA consultant proposes 2 public consultations to be held before commencement of construction: one for local officials and representatives of the mass organizations such as youth’s union, farmers’ union, women’s union and veterans’ union and representatives of the beneficiaries during preparation of the updated IEE and one for all of them right prior to construction. The former meetings’ objective is to introduce related groups about estimated timing and detailed content of subproject’s components as well as collect their opinions and recommendations on the subproject with focus on their concerns about construction and operation of the plant. The latter meeting is conducted right prior to construction to inform the beneficiaries about startup of



38


construction works and foreseen impacts and gather their concerns/ suggestions. The former meeting was held during preparation of FS and updated IEE while the latter will be done during the detailed design phase right prior to construction.

156. In this subproject, one main public meeting and several supplementary public meetings

have been held so far. The main public meeting was conducted on 5th November 2011, facilitated by PPMU staff with guidance and assistance from the PIA consultant. The venue of the meeting was in the meeting room of Tay Giang commune, Tay Son district, Binh Dinh province. This consultation is conducted during the phase of FS review and environmental assessment for subproject preparation. It was a follow up of the public consultation organized by the PPTA consultant in 2009 so its roles are to reintroduce about the subproject as well as update information related to the environment and obtain local people’s views on environmental aspects of the subproject. Photo 5 was taken during the main public meeting.

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.

159. 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 labor to the subproject. Issues and recommendations raised by the participants are summarized as follows:

(i). Densely populated hamlets have high demand for clean water and sanitation facilities. (ii). Representatives from affected households supports land acquisition for construction

of the project. (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 the operator of WTP to comply strictly with environmental mitigation measures and environmental monitoring plans during construction and operation stages.

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

160. A record of the main public consultation meeting minute in Vietnamese is attached in

the Annex 4.

161. In combination with CBA- IEC activities of the subprojects, some separate public consultation meetings 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, the females, the males and the ethnic minority (if there are ethnic minority people in the subproject area). A household survey was conducted mong 5% of the households in the proposed subproject area. The focus group discussions and the household survey were implemented by the CBA- IEC consulting group during February and March of 2012. Information collected from these meetings and the survey supplements the main 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 behavior. The information collected from group discussions served as a supplementary or comparative source of information during the field validation. The detailed results of Baseline survey are presented in Volume 2 of Binh Dinh SAR report.

6.2 Grievance Mechanism

162. 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; (b) disclosing all the safeguard documents; (c) receiving and responding to the comments/feedbacks from the community.

163. If people affected by the proposed Subproject have any grievances they could raise their concerns to the contractors, the CSC, the project owner 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, the CSC and the PPMU within 3 weeks from the date of complaint receipt. If the affected people are not satisfied with the resolutions or in the absence of any response within the stipulated time, 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.

6.3 Future Consultation and Information Disclosure

Future consultation

164. At least two future public consultations will be held right before the commencement of construction, and during construction following the general guidelines below:

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. 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

165. 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 project implementation Environmental monitoring reports.

166. The draft versions of IEE and SIEE were prepared by the PPTA in 2009. According to

the Loan Agreement, this IEE document has to be reviewed and updated in compliance with the Safeguard Policy Statement (June 2009). 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 IEE shall be attached in notification boards of Tay Giang and Tay Thuan communes. Other related documents shall also be attached for references. In addition, the IEE reports of the subproject will be disclosed at ADB office in Hanoi.

7 FINDINGS AND RECOMMENDATIONS

167. 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 a cultural and historical site i.e., the Caodaist Oratory Cultural site in Trung Son hamlet and the Three Golden Star Division Historical site along the National Road no. 19 in Thuong Son hamlet is 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 construction 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.



42


168. The potential adverse impacts associated with the subproject that would occur during the construction period 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 project implementation and operation phases so that they can intervene when necessary or when complaints arise.

169. 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 improved 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.

170. All subproject activities prior to construction, during construction and during operation will be managed as provided in the EMP and EMoP 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. Tay Son DPC also approved the Environmental Protection Commitment in accordance with Vietnamese regulations (see Annex 5).

8 CONCLUSIONS

171. Based on the screening process using the REA Checklist, the 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; Adjacent to or within special area for protecting biodiversity; and Although the Caodaist Oratory Cultural site and the Three Golden Star Division

Historical site are located in the Subproject area, these two sites are situated separately from the WTP area, wells location and distantly from the pipeline so they will not be encroached by the subproject.

172. The subproject has been classified as Category “B” project under the ADB’s Policy on

Environmental Assessment Guidelines 2003, so only an IEE report is required. Moreover, due to the nature of the subproject, location and environmental conditions of the subproject area, any special study or an EIA to comply with the environmental policies of the ADB are not required. Also, under the requirements of the Decree No. 29/2011/ND-CP dated 18th April 2011 On Strategic Environmental Assessment (SEA) and Environmental Impact Assessment (EIA) and Environmental Protection Commitment (EC) of the Government of Vietnam, the water supply scheme for the subproject do not demand an EIA study. However, the Environmental Protection Commitment has been registered and accepted by the DPC.

II. Public Consultation meeting content

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

1. Positive impacts

The construction of the water supply system will have positive impacts on the local socio-economic development, meeting the need of cleaned water for thousands of local people. Success of the project will help solving not only clean water condition of the two communal communities, but also improving people’s living condition in the Subproject area, improving the health and living standard of the people, environment protection, reducing the use of poor quality water, the shortage of water and decreasing waterborne diseases as well.

After construction is completed, the operation of the Subproject will favours environmental protection activities on soil, water bodies and air as clean and safe water is the primary factor that helps conducting protection 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 the environment and people’s 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.

2. 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:

- Transportation of construction materials, soil excavation and filling at WTP, 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.

- Waste water discharged from construction works such as storm water, waste water from treatment facilities (settling tank, filter, workshop, chemical house), domestic waste water from operators.



Annex 4.1

3


- 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.

III. Environment Management Plan

During the project implementation as well as operation of facilities, standards and solution mentioned in Chapter 6 of FS report and Chapter II “Mitigation Measures for Negative Impacts” of the Environment Protection Commitment need to be followed to minimize negative impacts on the Environment. The Environment Management Plan will be carried out in steps similarly as bellows:

Summary of environmental impacts of the project:

Environmental Impacts

Mitigation Measures Implementation Unit Monitoring

Construction Phase

Impact on soil Adverse impact is minor as the land use purpose for construction of WTP has been changed and the construction area is not large. For filled soil layer of the pipeline, the natural ecosystem of the surface layer will be recovered by itself, so this impact is temporary.

Contractor PPMU and District Division of Environment

Impact on air Adverse impact is minor and temporary as construction is small, short construction period and sparse population density. Closed monitoring of materials and chemical transportation is needed.


Impact on water bodies

Adverse impact is minor and in short period, low toxicity of water, self-cleaning ability of water body is much higher than the potential contamination impact of polluted substances. Closed monitoring of chemical used during construction is needed.


Impact on human activities

Manage the travel of vehicles properly to avoid

Accident and risks of explosion, fire

Workers must be fully equipped with working clothes, hat, gloves, shoes, glasses, safety belt,… machines, equipment must include a history of operation and be regularly checked.


Operation Phase

Impact on air - Air pollution control is mainly to decrease or remove leaked Chlorine gas, which is used for disinfection.

- Machines, equipment used for the project should be new and modern. Pumps and mixing devices are run by electrical motors; manufactured by developed countries, so they will not cause vibration and noise that are beyond allowed limits.

- Planting trees is very useful to the climate and the environment.

Impact on water bodies

- Treatment of domestic wastewater within WTP

- Treatment of waste water from WTP

- Treatment of oily waste water.

IV. Comments from Local Government and Representatives of Community: Comments from Local Government:

The project brings to the people of Tay Giang and Tay Thuan Communes great, practical and long-term benefits. Implementation of the project 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



Annex 4.1

stipulated in the Project Investment Report and the Registration for Environmental Protection Commitment.

The Project Management Unit as well as the Contractor are requested to provide specific assignments of Environmental Monitoring as specified in the Project Investment Report for sustainable development of the project. The Local Government of Tay Giang and Tay Thuan Communes commit to comply with provisions of the Environmental Protection Commitment, encourage people to overcome difficulties and agree on project implementation.

Comments from Representatives of Community:

Representative of Vietnamese Fatherland Front Committee of Tay Giang Commune: The project brings practical benefits to the people, improves the living conditions, reduces diseases related to polluted water and environment. Although the implementation of project has impact 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 Project Investment Report. Therefore, the Vietnamese Fatherland Front Committee of Tay Giang Communes agreed on project implementation.

Representatives of Women’s Union of Tay Giang Commune: After listening to the Project Investment Report presented by the Consultant’s Representative, Representatives of Women’s Union of Tay Giang Commune felt very excited because the expectation of Tay Giang 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 hygienic latrines. During implementation of Project, 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 Project Investment Report. Therefore, the Women’s Union of Tay Giang Commune agree on early implementation of project.

Representative of Farmer Association of Tay Giang Commune: Highly agreeing with opinions of the Government and Unions, the Commune’s Farmer Association hoped that the project 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 project, the Association will mobilize the people to cooperate with concerned parties to overcome and reduce such negative impacts.

Representative of Health Center of Tay Thuan 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 project is necessary to the people of Tay Giang, Tay Thuan Communes. During implementation of project, there will be negative impacts on the environment and people’s lives. However, with the measures provided in the Environmental Protection Commitment 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 kindly request to implement the project soon.

Representatives of beneficiaries

Mr. Diep Bao Tai, from Thuong Giang 2 hamlet, Tay Giang commune: Our hamlet is very crowded with limited residential land. Clean water and sanitary facilities are an urgent demand. If



Annex 4.1

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. Do Loc, from Thuong Giang 2 hamlet, Tay Giang commune: I represents the affected households of land acquisition. I really support the project as it is a public project bringing benefits of health improvement to all of the local residents. I agree to allocate land to the project though I understand that during construction, we may encounter some difficulties. Hence, I request the construction team to propose sound construction measures and time to mitigate the negative impacts of construction.

Mr. Nguyen Huu Vinh, from Thuong Giang 1 hamlet, Tay Giang commune: In our hamlet, most of the households have registered to participate in connection to pipeline and construction of toilets. 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.

Opinions of representative of division of natural resources and environment of Tay Son district

- agreed with the presented positive and negative impacts that the Subproject will potentially cause on the environment;

- requested Binh Dinh Provincial Project Management Unit (PPMU) to ask Contractors to properly carry out the environmental impact mitigation measures stipulated in the Initial Environmental Examination report as well as environmental management plant during construction and O&M.

Participants also express their desire on timely construction of Subproject structures for early access to clean water supply and hygiene sanitation for local people.

V. Conclusions

Discussion on the meeting showed that local authorities and communities highly agreed with and supported the Subproject and expected that the Subproject will be commenced soon. They request the Subproject owner to comply with environmental protection measures which are stated in the Initial Environmental Examination report during Subproject implementation.
