5 I. GENERAL INTRODUCTION The Quy Nhon city - Binh Dinh Province is surrounded by the Sea in the East, and it is bounded by Tuy Phuoc district in the West, by Phu Cat and Tuy Phuoc districts in the North, by Song Cau District - Phu Yen province in the South, with the area of km 2. Quy Nhon is one of the six first class urban centers directly under the province of Vietnam and the centre of economy, politics, culture and tourism of Binh Dinh province. Quy Nhon city has 21 administrative units comprising 16 precincts and five communes. Nhon Hoi Economic Zone the key one of Binh Dinh province is invested to be constructed on the territory of Nhon Hoi commune belonging to Quy Nhon City. Nhon Hoi Economic Zone with the area of 12,000 ha will have Quy Nhon city enlarged to be the center of industry, port service, commerce, tourism, education and training of the Central coastline area. Currently, Nhon Hoi economic zone, the load in area of Nhon Hoi commune and part of the load of Quy Nhon city is received electricity from Quy Nhon 2 110kV substation with a capacity of about 8MW. Based on analysis of existing sources and the power grid there should not meet the load demand during the time when non-tariff zone (capacity of about 7MW), Nhon Hoi container port (capacity about 6MW) came into operation and the development of other services in synchronisation with Nhon Hoi economic Zone in the future. Therefore, the need to invest some 110 kv substation to the local load must be considered, in which, it is necessary to build Nhon Hoi 110kV substation and branch line to provide load for investors in Nhon Hoi Economic Zone. Aware of the need to implement of this project construction investment, Binh Dinh Province has asked the World Bank (WB) for sub-project financing. Sub-project "Nhon Hoi 110 kv Substation and branch line" that is one of the sub-projects will be implemented in Phase I of distribution efficiency project (DEP) under the Electricity of Vietnam by World Bank loans. Sub-projects will be implemented in Tuy Phuoc district and Quy Nhon city, Binh Dinh Province. The subproject activities include: i) Construction of an 110/22KV substation; ii) construction of the control house, distribution system, and the shifting house of the substation; and iii) newly built 110KV branch line of 26.33km long, in which in which there are 2.46km to be gone together with the power line to An Nhon. These activities can cause negative impacts on the environment and local communities during pre-construction, construction and operation. In order to ensure that potential negative impacts can be identified and during the preparation and mitigated during the subproject implementation process and that the subproject complies with the Environmental Assessment Policy OP / BP 4:01) of the World Bank, an Environmental Management Plan (EMP) of the sub-project has been prepared that follows the guidance provided in the Environmental Management Framework (EMF) of the DEP project. This EMP includes: the sub-project description, policy framework, applied environmental technological standards and regulation, potential negative impacts, proposed mitigation measures implemented during pre-construction, construction and operation, implementation arrangement of EMP and budget. The EMP will be incorporated into tender documents and contracts, along with environmental monitoring and supervision. According to the EIA regulations of the Government, the subproject is subject to the preparation of an Environmental Impact Assessment Report (EIA). This report was prepared and approved by Binh Dinh Provincial People Committee under Decision No No 544/QĐ- CTUBND dated 23 March Report on Environmental Management Plan Page 5

17 IV. SUMMARY OF SOCIO ENVIRONMENTAL BACKGROUND IN THE SUBPROJECT AREA 4.1. Geographical Area Binh Dinh is located on the coast of Central Vietnam, the province's territory stretches 110km along the north south with the average narrow width of 55km (narrowest place is 50km, maximum width is 60 km). It is surrounded by Quang Ngai in the north with the common border of 63km, the South China Sea in the east with the coastline of 134km, Phu Yen in the south with the common border of 50km Gia Lai in the west with the common border of 130km. Binh Dinh is considered a gateway to the sea of the Central Highlands provinces and southern Laos. The total natural land area of Binh Dinh province is 6, km2, the province's population is 1,489,900 people, a population density of 247 people per km2 (2009 data). On the administrative organization, Binh Dinh has 11administrative units, Qui Nhon city is the provincial capital that is first grade city and10 districts are: An Lao, Van Canh and Vinh Thanh (mountainous districts), Hoai An, Tay Son (Midland districts), Hoai Nhon, Phu Cat, Phu My, Tuy Phuoc, An Nhon, (deltaic districts), the whole province has 159 communes, precincts and townlets (of which: 129 communes, 14 townlets, 16 precincts). Currently, Qui Nhon city is the center of politics, culture of Binh Dinh Climate, Topography and Pedology a) Climate The climate of Binh Dinh Province in general, Qui Nhon and Tuy Phuoc in particular have humid tropical monsoon climate, due to the complex topography when the monsoon got into the mainland, its direction and intensity has changed quite a lot. The annual average air temperature: in the mountainous area varies from 20.1 to 26.1ºC, the highest one is 31.7ºC and the lowest one is 16.5ºC. In coastal area the annual average air temperature is 27ºC, the highest one is 39.9ºC and the lowest one is 15.8ºC. - Monthly average absolute humidity in the year: in the mountainous area varies from 22.5 to 27.9ºC and the relative humidity is 79.92%, and in coastal area average absolute humidity is 27.9% and the average relative humidity is 79%. - Precipitation: Rainy season starts from August to December, sunny season from January to July. Particularly, mountainous areas have one more aid rainy season lasting from May to August under the influence of Highland s rainy season. The dry season lasts from January to August. For the mountainous districts, the average rainfall during the year from 2,000 to 2,400mm. For coastal areas, the total rainfall is 1,751mm. The total rainfall tends to decrease from the mountainous area to coastal one and from the Northwest to Southeast. - About storm: Binh Dinh is located on the coast of Central Vietnam, so the storms are often landed the mainland. Annually in the coast from Quang Nam-DaNang to Khanh Hoa there is the average of 1.04 hurricane landfall, frequency of typhoons appearance from September to November. b) Topography: The line goes through Tran Quang Dieu precinct, Phuoc Hoi commune belonging to Quy Nhon city and towlets of Dieu Tri, Tuy Phuoc, communes of Phuoc An, Phuoc Loc, Phuoc Nghia, Phuoc Son, Phuoc Hiep, Phuoc Hoa belonging to Tuy Phuoc district, Binh Dinh province, it almost goes on the hillsides, there are several sections running through sparsely Report on Environmental Management Plan Page 17

18 populated areas and Industrial Zones in relatively flat terrain, in ROW there are some crosslines such as Highway No1A, Highway No19, provincial road 638, 639, 640, intercommunal, inter-village, productive road, planning road in Industrial Zone, so that the transportation of equipment, materials and construction apparatus is rather favorable. Particularly, the terrain at the start route section as well as at the end route section is rather complicated, the elevation changes constantly, most line route goes on the high hills and mountains so it s very difficult in execution latter. c) Pedology: Geology here is mostly land of gray, gray brown, clay, loam of the yellow, lemon yellow, medium grained quartz sand coarse medium light gray, pale yellow and quite a lot of shells, livid and dark blue clay. Heterogeneous structure and content of rock chips and pebbles stone is quite large, 5.0 meters thick Natural Resources Soil resources: The natural area of Binh Dinh province is 6.039km ², there are11 groups of land with 30 different kinds, of which, the alluvial land accounts for 71,000 hectares. Currently there are approximately 136,350 hectares of agricultural land, 249,310 hectares of forestry land, and 62,870 hectares of non-agricultural land, over 150,000 hectares of unused land that can be exploited to develop agriculture, forestry and other uses (2009 data) Rivers and streams: Binh Dinh river system mostly stems from the high mountains of Truong son Mountain range to the east side, the rivers are not large, high slope, short, low in silt content, The total water volume is 5.2 billion m3, hydropower potential is million kw. There are four major rivers in the province, they are Con river, Lai Giang river, La Tinh river, Ha Thanh river and small rivers as Chau Truc or Tam Quan ones. The province has about 15 artificial lakes and 03 fresh water lagoons that are favorable for the development of agriculture and aquaculture. Especially the big Thi Nai lagoon is favorable for the development of national-caliber port and contributes to the development of Nhon Hoi Economic Zone, Thi Nai lagoon has the largest over sea bridge in Vietnam today. Mineral resources: Binh Dinh has many kinds of minerals such as bauxite, gold, titanium, ilmenite placer... and some non-metallic minerals such as kaolin, white sand, granite...in the whole province there are 5 points of mineral springs: Hoi Van, Chanh Thang, Dinh Quang, Vinh Thinh, Long My. Especially hot mineral water quality of Long My reaches international standards, it can be exploited 50 million liters / year. The project did not go through the area with the resources listed above. Marine and coastal resources:binh Dinh has a coastline of 134 km with three large bays: Qui Nhon, De Gi and Tam Quan, has Thi Nai Lagoon and more than 7600 hectares of water surface capable of aquaculture and marine products. Binh Dinh marine ecosystem is suitable for many types of seafood that are of high value and preferred by domestic market as well as foreign one. The coast has many beautiful landscapes. However, the project is not located in this area. Flora and fauna resources: With hot and humid climatic conditions, rainfall, diversified topography and land, vegetation in Binh Dinh is abundant in genders and species, there are 66 classes, 175 groups, 1,848 species. Wildlife in Binh Dinh forest are associated with animal systems of Kong Ha Nung (Gia Lai), Ba To, Tra Bong (Quang Ngai),Tra My and Phuoc Son (Quang Nam) includes seven classes with 19 groups, Report on Environmental Management Plan Page 18

19 38 species and 13 classes of birds with 37 groups, 77 species. However, the project area is located away from these areas; flora in this area are mostly rice and crops and some fruit trees, common timber; animals are mainly domestic ones as the special livestock, poultry, wildlife mainly birds, bats, squirrels Traffic system The transportation system in Binh Dinh province is rather synchronous. Highway No.1A (runs through the province from north to south with a length of 118 km), national railway (150 km through the province) runs through the province from north to south along with Highway No.14D (34km long); Highway No19 (70km through the province) that connects Qui Nhon port to the outside is very convenient, Phu Cat airport that is 30km far from Qui Nhon city to the north has been opened more flights to welcome passengers to and from Binh Dinh. Notably, the coastal road connection from Nhon Hoi to Tam Quan facilitates socio-economic development and exploits the potential of the province s hills and mountains. The traffic conditions in the project area is relatively favorable, construction site position is about 300 meters far from Highway No.1A, in the substation location there s the planning road in the Industrial Zone so it is very convenient for the transportation of materials and equipment V. POTENTIAL IMPACTS Table 4: The project potential impacts are described in the following table: No Impact Yes No Description of impact Construction preparation stage 1 Acquisition of land temporarily and permanently? 2 Impact of affected households? 3 Any household needs to be relocated? Yes Yes No - Short-term impact because of temporary land acquisition for ROW and construction. - Long-term impact because of permanent land acquisition for tower foundations and substation. - The area of permanent land acquisition is 9,600m 2, the area of temporary land acquisition is 385,150 m households whose crops and trees are affected, but mainly due to the construction of tower foundations, the area of land acquisition is minor, while the substation is built on the available land of the Economic Zone NPMU will satisfactorily compensate the permanent as well as temporary affected land, houses and trees. None of households must be resettled. 4 Affected to the Yes - Any tree higher than 4m in ROW where the Report on Environmental Management Plan Page 19

20 No Impact Yes No Description of impact flora due to transmission line runs through will be cut down. clearance for - When constructing the T/L, soil excavation, site ROW? clearance and other activities in the ROW are unavoidable. The land area for the ROW is about (including the land area for tower foundations): 26,330mx 15m = 394,950m 2. All the damage about trees will be appropriately compensated under the regulations of the Government. 5 Any impact on natural conservations? 6 Any risk to people s health caused by explosive or chemical substances? 7 Any devalue of cultural and historical works? Construction stage 8 Does soil erosion cause pollution to the surface water and conductor stretching affect rice fields and shrimp ponds of the people, affect traffic when crossing roads.? 9 Noise, and vibration, and dust? Yes Yes No No No The transmission line and the location of installing the substation do not run through any natural forest, protection forest or conservations, so the clearance does not affect the flora and fauna in the area. The project does not use chemical substance and explosive. - The T/L and s/s is not in the area where there are cultural, historical and public works so it does not affect on them. - When excavating for tower foundation and substations, objects of cultural / historical values may be discovered. Construction units should follow the guidance in Item 14, section the measures to minimize environmental impact. - When excavating soil at tower foundation positions and the substation one (foundation of transformer, shift dorm, control house), the surface soil will be excavated. When it rains, this surface soil will be eroded and swept away. Materials for construction will be scattered if they are not protected. While stretching conductor will affect rice fields and shrimp ponds of the people and affect traffic when crossing roads. - Noise and vibration are caused by material transportation means and some activities of the project such as: tower erection, conductor stretching and generator. - If the construction work is near other Report on Environmental Management Plan Page 20

21 No Impact Yes No Description of impact infrastructure ones, it must be embanked and covered in order to avoid landslides by vibration and limit the effect on adjacent works. For this project, its position is far from other infrastructure works so there is no impact on them. 10 Air pollution? Yes - Air pollution can be occurred due to the exhaust and dust of material trucks during transportation, loading materials; or dust during project implementation. 11 Rural traffic obstruction? 12 Any damage or degrading to rural traffic-ways and traffic safety? 13 Any damage to biological diversity? Yes No No - However, with the average number of 1 truck per week - 2 trips per day for every tower foundation and 2 trucks per month 2 trips per day for substation (implementation in about 2 months) (see the main volume in table 2).Therefore, the level of dust and exhaust by transportations affected on the environment is minor. - Materials and equipment are transported in long distance from the yard and storehouse of Investors by specific trucks with suitable form of packaging goods and equipment to the temporary project storage. After that, they are transported to the construction sites by 5 tons to 7.5 tons trucks. Building materials such as: sand, grits, stones, cement will be supplied by suppliers who have got business license in locality and transported directly to the construction sites. - With the average frequency of transporting as above (item 9) and constructing activities such as: soil excavating and conductor stretching, local traffic obstruction will happen. However, the time for loading materials and equipment is short (about 1 hour), building materials (sand, grits, stones, soil, etc) is loaded by dumper trucks so the level of traffic jam is not high. All materials and equipment are classified for transportation in accordance with the load of the roads; traffic here is an asphalt road (Highway No14, provincial roads and some other intervillage, inter-commune roads). In the project construction site, no species of wild animals and plants live. The permanent acquisition land is about 100m 2 /1 tower foundation (86 positions) and acquired substation of 4,651m 2. These positions are located far away from each other, in a distance of a tower foundation (about 250m); particularly the leveling area for substation Report on Environmental Management Plan Page 21

22 No Impact Yes No Description of impact is too minor and mainly industrial crops and fruit trees of the households. Therefore, as the level of flora surface clearance as well as land acquisition for animals is not considerable, there is no loss to the biological diversity in the area. 14 Solid waste causes by soil excavation, tree cutting in ROW and constructing activities? 15 Any impact on environment caused by the workers? 16 Is there any conflict between construction workers and local people? Yes Yes Yes Solid waste due to soil excavation (remains of soil and stones), tree cutting (body) or construction activities (junk iron, stones, sand, plastic bottles, cement wraps) will arise during implementation. The impacts of solid waste will be minimized through waste reduction practice and the other measures presented in Item 6.1 of this EMP. It is expected to build 01 camp in construction site of substations for workers. Local people s houses will be rented for warehouses and storehouses of materials and equipment. Therefore, water and sewages of workers will affect the surrounding environment if no method to protect the environment is applied. However, the organization of construction site is always concerned by the investors and always be expressed in the bidding documents, contract terms, therefore there are measures to handle each environmental issues during construction such as installing septic tanks, create drainage channels, installing manholes septic, etc in compliance with the regulations of the local area. Hence, the impact on environment by workers is not considerable. The appropriate mitigation measures specified in Item 6.1 of this EMP will be implemented to minimize impacts to the environment from workers. - There are differences between the workers and local people in income, lifestyle and custom. However, there is no deep conflict between them because they all use Vietnamese as a means of communication. The workers have to follow contractors regulations as well as local ones. Besides, to minimize the risk of conflict, the project uses some local labors in manual work. So, there is no big conflict between workers and local people. - Otherwise, the project will bring benefits to the local community so it gains lots of agreement from the local people as well as the close coordination with local Authorities. 17 Health and safety Yes Accidents can occur during implementation if Report on Environmental Management Plan Page 22

23 No Impact Yes No Description of impact for workers and local people? safety regulations is not strictly followed, such as: checking tools before use, setting up danger indicators (at sites of incomplete tower foundation, at sites of generators and conductor stretching, sites near roads, sites where loading materials and equipment is being carried out, sites where there are people working high above). These accidents can happen not only to the workers but also to local people. These risks can be limited more by the application of mitigation measures specified in Item 6.1 of this EMP. 18 Any landmine or bomb left after war? 19 Any other special effects due to construction activities: tower foundation excavation and conductor stretching? Operation stage 20 Development and poverty reduction? 21 Causing partition of natural environment that lead to the easy invasion into wild land? 22 Health and safety for operators and local people? Yes Yes Yes No In the past, this area was at war but the war raged less than other regions. However, the years of the war was over, this area has been exploited and constructed many works, so the remained landmines or bombs after war are inconsiderable. During tower foundation excavation in the area of rice fields there will affect irrigation canals in this area. The conductor stretching will affect crops, rice and trees of the people in the region. These risks can be limited more by the application of mitigation measures specified in Item 6.1 of this EMP. - Mainly taking part in the attraction of investment and local economic development because industrial production cannot be done without power. - Assisting agricultural production and other services including healthcare and education. - The project does not build more temporarily access roads. - After the construction of tower foundation, the temporary acquired layout will be returned as it was in the past. The entire flora less than 4m in the ROW will be remained so the impact to natural environment is inconsiderable. The project is not located in wild land so there is no impact. Electrical shocks and other accidents can occur. However, all measures and safe tools are always checked under the regulations for every tool and frequently before use. Danger indicators always have to be remained so accidents are unlikely to happen. Report on Environmental Management Plan Page 23

24 No Impact Yes No Description of impact 23 Electromagnetic field? 24 Any impact on planes, birds and bats? 25 Any pollution by oil-wastes? 26 Risks of fire and explosion? Yes No No The transmission line and the substation are designed, constructed according to the current regulations and standards of the Power Sector, in which the calculations of the effects of electromagnetic fields and standards to ensure electrical safety, operational safety has been calculated to avoid harm. Before putting the project into operation, all safe indicators have to be specified through tests, experiments and acceptance to ensure that they meet the standards and regulations set by the investors, Construction Unit, Operational Management Unit so the operators and the local people will not be harmed by electromagnetic field. In the project area, there are only some flying animals like bats or squirrels but a few kinds of birds and domestic animals, so there is no impact on flying animals. The tower/pole height is about 32 m to 37 m. Therefore, the poles will be equipped with signals for safety flight inside and surrounding the region, particularly helicopter operations or activities of take-off and landing outside the airport. The project does not remove the old transformer and does not use the equipment that contains PCB and other dangerous chemical substances. Transformer oil may be leaked in case of failure. However, this is rarely occurred and there is already the tank for containing this oil. Leakage oil will be refilled into the transformer without spilling on surrounding areas and without pollution caused by oil sewage. Yes Transformers and other equipment can be exploded and transformer oil can be leaked when faults occur. Therefore, fire-fighting equipment and fault oil tank must be equipped.
