5 EFFICIENCY IMPROVEMENT OF I 10KV DISTRIBUTION NETWORK PROJECT NORTHERN VIETNAM CHAPTER I INTRODUCTION The System Efficiency Improvement, Equitization and Renewable Project including construction and rehabilitation of a number of power transmission and distribution lines and substations, is proposed to be funded under a World Bank credit. The Government of Vietnam is seeking assistance from the WB to improve the efficiency of its power sector so that poverty alleviation programs can take root. One of the project component is for Efficiency Improvement of 110 kv Distribution Network in Northern Vietnam implemented by the Power Company No 1. According to the Bank's requirement, an environmental assessment of the project is required to ensure that the project is environmentally sound and sustainable. This EIA report follows WB and Government of Vietnam guidelines for assessment of environment impacts and mitigation strategies for power projects. The objectives of the report are: - Assessing the current environment status of the region, where the project is located. - Identification of potential impacts to the environment in the case of the project will be developed (in the period of construction and operation) - Screening, classification of the impacts (none, small or major) - Identification of the measures to mitigate the negative impacts caused by the project construction and operation - Developing an appropriate environmental management plan - Estimation cost of the proposed mitigation measures. Methodology: The method applied in the report is based on environmental checklist Based on the guidance on ELA by World Bank, the potential environmental impacts are classified with levels as follows: a. Little impact or negligible impact: For these impacts do not need to have measures for mitigation. b. Having impact but not much: For these impacts, the measures for mitigation must be shown. c. Significant impact: For these impacts, they are necessary to have strict research, and measures for precaution have to be designed more carefully. 5

15 EFFICIENCY IMPROVEMENT OF 110KV DISTRIBUTION NETWORK PROJECT NORTHERN VIETNAM CHAPTER IV PRESENT STATUS OF PROJECT SITE ECOLOGICAL AND SOCIAL CONDITIONS: In terms agro-ecological setting, Vietnam can be divided into 8 separate regions, different on the basis of topography, annual rainfall, inherent susceptibility of the land to deterioration and the types of dominant land forms. The project components are located in 4 regions namely Red River Delta, Northern Midland, Coastal Delta and Northem Mountainous. Details of natural and socio economic conditions of project involved provinces are provided in Table Red River Delta (Thai binh, Nam ha provinces): There are 3 following subprojects - 1l OkVDong Van substation and 110 kvly Nhan - Dong Van T/L kv Vu Thu substation and 110 kv Thai Binh - Vu Thu TIL kv TIL Thai Binh - Kien Xuong and 110kV Kien Xuong substation Topography, Hydrogeology and ecological condition: Red River Delta is the second largest delta in Vietnam after Mekong delta. The climate is monsoonal, with 1,678 mm of annual rainfall coming from late April to October. The flat topography, generally low susceptibility to deterioration, and alluvial soils make it suitable for intensive agriculture. The region has low elevation of less than 50 m over sea level. The land is mainly covered by two crops-paddy and other kind of crops fields. Household also have garden with long tern fruit trees. There are no forest or wild land in the area. There are many small canals and rivers in the regions. Locating in riverhead region with elevation slopping down, the project area is usually affected by floods in rainy season Social-economic Condition: This area is highly populated. The economic activities of the area mainly base on agriculture, focusing on rice and other kind of crops as maize and vegetable. Industry, including rice milling, construction material production, and small industries and handicraft, accounts for small portion of the region GDP. The living standards is rather low compared to that of urban population Northern Midlands (Quang Ninh, Bac Giang, Thai Nguyen, Vinh Phuc, Phu Tho, Thanh Hoa provinces) : including 05 subprojects - 11OkV Viet Tri - Lap Thach T/L and 110 kvlap Thach substation kvphu Tho substation and branch kv North Viet Tri and branch - 10 kvbac Giang - Luc Ngan T/L and 110 kvluc Ngan substation kv Vinh Tuong substation and branch Topography, Hydrogeology and ecological condition: The climate is monsoonal with an average yearly rainfall of 1,600 to 2,500 mm largely occurring from late April to October. The soils are acidic and have low fertility rates. The region has elevation between 50 m and 500 m. Even through geography of the area is rather complicated with many different soil layers, soil structure is quite stable. 55% of the region has medium susceptibility to deterioration or erosion. In valleys or relatively flat areas, the land is covered by 15

16 EFFICIENCY IMPROVEMENT OF I 10KV DISTRIBUTION NETWORK PROJECT NORTHERN VIETNAM one crop-paddy fields, maize and cassava and other subsidiary crops. In low hills, there are planted fruit tree or industrial trees such as gum tree, eucalyptus, caesarian-tree and planted forest Social-economic Condition: The region is less populated than delta area. The economies mainly base on agriculture focusing on rice and other crops. Their industries are small with main focuses on processing of agricultural and forestral product and production of construction material. The GDP level is normally lower than in Delta provinces Northern Central Coast (Nghe An, Ha Tinh provinces): including 3 subprojects: - Cua Lo-Dien Chau-Quynh Luu 110 kv T/L and 110 kvdien Chau substation kv Tinh gia substation and branch kv Can Loc substation and branch Topography, Hydrogeology and ecological condition: The climate is monsoonal with an average yearly rainfall is 2,890 mm which is peaks in October and November, and typhoons are common from May to August. Yellow red soils dominate the upland, alluvial soils in the low lands and sandy soils in the coast. 37% of this region has medium susceptibility to deterioration. The main form of topography is midland with elevations between 50 m to 500 m. The regional hydrogeology is sophisticated. There are a number of small streams and rivers which usually cause floods in the time from July to October. The land is covered with: + Traditional fruit-tree and industry crop: eucalyptus, pine, coffee.. + Naturally planted forest in low mountain areas. + Paddy, crop fields in low land Socio- economic conditions: In this area, the economy foundation is mainly agriculture such as rice, farm production, fishery, and rearing, marine product processing at small scale. Due to frequent floods, typhoons and low fertility rate of land, the region is quite poor Northern Mountains (Tuyen Quang, Lao Cai, Yen Bai, Lai Chau, Son La provinces): Including the following 10 subprojects: kv Ba thuoc substation and Thieu Yen - Ba Thuocl 10 kv T/L kv Nghia Lo substation and Yen bai- Nghia Lo 110 kv TEL kv Phu Yen substation and branch. + Tuyen Quang - Chiem Hoa 1 10 kv T/L and 11 0 kv Chiem Hoa substation kv Quang Ha - Cho Roc substation and branch kv Phong Tho substation and Lao cai- Phong tho 11l0 kv TL kv Thuan Chau substation and branch kv Tuong Duong substation and Do luong- Tuong duong 1 10 kv TIL. t 110 kv Phu Luong substation and branch. 16

17 EFFICIENCY IMPROVEMENT OF I 10KV DISTRIBUTION NETWORK PROJECT NORTHERN VIETNAM Topography, Hydrogeology and ecological condition: The climate in the region is similar to the Northern Midland with average yearly rainfall of 1600 mm to 2,500 mm. The region has elevation over 500 m. The elevations are lower from the North to the South, from the West to the East. Intense rainfall combined with steep topography and frequent seismic activities make 47% of the Northem Mountains highly susceptible to deterioration or erosion. The soils are acidic and have low fertilities rates. The soil structure is quarterly sentiment composed of clay layer, loam, and sandy clay with broken stone and boulder. The regional hydrogeology is sophisticated, too. These mainly are small streams and rivers which usually cause 3-10 day floods in the rainy season. The water discharge in the dry season is very low. Though the northem provinces used to be covered with primitive forests with precious timber species as: dalbergia, sindota vietnamiensis, ironwood, etc.. as well as valuable animals such as tigers, bears, panthers, deers, wolves, foxes. In recent years, however, the forest have been destroyed badly. And as a result, such precious trees and animals mainly exist in high mountains, isolated and strongly divided areas without no access roads and human. The remaining areas are covered with planted forest, one crop fields of cassava, maize or paddy. There are also bald hills resulted from unplanned deforestation activities Socio-economic condition: The region is sparsely populated. The economies of the provinces mainly base on agriculture and forestry. Their industries are mainly in small scales and focus on processing of agricultural and forestrial products, production of construction material. In many highland areas, subsistence economy is still popular with low level of market activities. The region is one of the poorest areas of the country with highest number of comnmunes under Government Poverty Reduction Program. 17

I ASSESSMENT5n XVI 11 LIt VIETNAM tnd CHAPTER V IMPACTS ON ENVIRONMENT The project impacts on the environment can be divided into: - Impact on physical environment - Impact on biological and ecological system - Impact on human - hnpacts on telecommunication systems, on landscape, cultural reserves and others The environment issues caused by the project are as in the following: I. IMPACT ON PHYSICAL ENVIRONMENT: The impact on physical environment considered here is the impacts that may be caused by the project components on water, air and land. The project is to build new 110 kv transmission lines and substations, in general there are little impacts on physical environment during the project construction and operation. Negative environmental impacts are caused by construction of transmission lines, access roads, tower pads and substations, These include runoff and sedimentation from grading for line and substation facilities; loss of land and increase in soil erosion due to placement of towers and substations; oil contamination from construction equipment; dust, noise and vibration due to material transportation and construction works; disposal of installation and construction materials. These impacts are more significant in the populated areas and should be dealt with by appropriate mitigation measures to comply with the national environmental standards on quality of water, air and land. Erosion of land could be caused during construction of power tower foundation and wire stringing or by construction of temporary assess roads. During the operation phase, soil erosion and landslide could be still a problem in the vicinity of the tower pads if not managed and controlled properly. This should be paid with attention where the topography is sloppy or the foundation morphology is not very strong in the Read river Delta or North central coast such as in Dong Van, Tinh Gia, Thai Binh-Kien Xuong... Soil erosion and landslides may occur also during implementation of site clearance of I I OkV substation Noise caused by arcing flashover in rains or very humid condition will not be considered as it is considerably small (<IOdB under the line). Works of tower foundations and tension foundations may also cause negative impacts on underground water. However, due to swallow depth of foundation works ranging from 2m to3m, if using simple tools, the construction would not affect underground resources. II. IMPACT ON BIOLOGICAL ENVIRONMENT ANND ECO-SYSTEM: 19

20 EFFICIENCY IMPROVEMENT OF 110KV DISTRIBUTION NETWORK PROJECT NORTHERN VIETNAM Construction and operation of 110kV distribution network may cause some negative impacts on biological and ecosystem due to site clearance and maintenance of the project Right of Way (ROW) and substation site. Effects on land use: The total land to be permanently and temporary used for the project is 16,384,294 m 2. in which For transmission line. - Temporary acquisition land within ROW areas 10,637,549 m 2 + Residential land within ROW: 131,775 M 2 + Weste land: 669,022 m 2 + Agricultural, Forest: 9,806,752 m 2 - Permanently acquired land: 195,048 m 2 + Residential land: 1,747 M 2 + Weste land: 31,518 M 2 + Agricultural, Forest: 161,783 m 2 - Temporary land acquisition: 5,551,697 M 2 + Residential land: 73,099 m 2 + Weste land: 426,918m 2 + Agricultural, Forest: 5,051,680 m 2 - Secondary forest within ROW: 882,000 m 2 - Secondary forest temporary acquisition: 316,465 m 2 - Secondary forest permanently acquisition: 14,541 m 2 - Area of trees cut down: 1,213,006 m 2 The total territory of secondary forest in the project affected areas: affected forest areas accounts for approximately 7.5% of the total forest land. For substation. - Permnanently land acquisition by substations 161,788,158 m 2, so the ( Agricultural land, Waste land, Hill land... ) 83,310m 2 Details are provided in Table 4.2,4.3.1, 4.3.2, 4.3.3, and 4.4. Theoretically, the project can open up more remote lands to human activities and construction of ROW can result in the lost and fragmentation of habitats and vegetation along the ROW. However, in this project, since the route lines have been chosen to mainly go along the existing roads, all components do not traverse through protected areas, with natural primary forest or areas with high biodiversity, which are present in five provinces. In Northern Mountains region, there are 5 subprojects: 110kV T/L Lao. 20

21 EFFICIENCY IMPROVEMENT OF 110KV DISTRIBUTION NETWORK PROJECT NORTHERN VIETNAM Cai-Phong Tho, 110kV T/L Tuyen Quang-Chiem Hoa, 110kV Ham Yen branch, 110kV Phu Yen branch, 110kV Quang Ha branch that will traverse some planted forest (or secondary forest) in Nghe An, Yen Bai and Son La province. However, the total land acquired for the ROW accounted for less than 7.5 % of total forest areas, thus the impacts are insignificant. Details for the impacts for these lines are provided in Table 4.2. Effect on clearing and control of vegetation in ROW According to Vietnamese standards on safety of ROW network, for 110kV T/L, the ROW is limited by 2 parallel corridors of 4m out from the outer conductors in vertical position. The trees outside the ROW must be controlled to ensure there is a distance of 0,5m from trees to conductors when they falling down. The vertical clearance requirement from conductor to top of the trees in the ROW must be not less than 3m. As such, all trees of or would be > 4m in the ROW must be cut down. As the result trees that would be > 4m height shall not permitted to plant within the ROW. Therefore if the TIL routes traverse natural and industrial forests with trees higher than the limit, such trees must be cut down as well. This would have certain impacts on the biological and ecological environment. 22 subprojects of efficiency improvement of 110kV distribution network of which 110kV Do Luong-Tuong Duong T/L and Phu Yen 110kV T/L would traverse parts of natural and planted forests ( More detailed description provided in the table No. 2) 21

However these impacts are only temporary affections (with duration of from 3 to 6 months). The 110kV T/L traverses planted forest including 05 subprojects: 110kV T/L Lao Cai-Phong Tho, 110kV T/L Tuyen Quang-Chiem Hoa, 110kV Ham Yen branch, 110kV Phu Yen branch, 110kV Quang Ha branch. Trees should be cut down in the planted forest areas that traversed by the line routes. There may cause small impacts on eco-system, nature sources but the balance of ecological system would not be affected. A number of these impacts was summarized with details in the below tables No 4.3,

34 VIfETNAMl IIl. IMPACT ON HUMAN: 1. Impact on residential areas: The line routes are normally selected to be close to transportation roads so as to facilitate construction, operation and maintenance in the future. Substation sites are selected to be close to the load center, i.e. be close to a residential or industrial areas. As such, outgoing feeders and I 1OkV TIL connected to substation may traverse houses. In order to avoid houses, the line route was designed to tum frequently with numerous small angles. The project causes no significant impact on residential areas. However, the survey data show that there's still small number of houses affected by line routes (about 5%). Details are provided in Table 4.3. Impact of noise, vibration and pollution for residential areas: Machine operation during construction may cause noise and vibration including trucks for equipment and material transportation. However noise, vibration level is less than 5OdBA, the permitted noise level. As the voltage levels are 1 IOkV, noise caused by arcing flashover in light rain or humid condition is insignificant, much lower than permissible level. Pollution of dust, noise to human residential area may occur during construction period. However load truck transporting material on roads near residential areas will be required to be covered. The noise level from trucks is not exceed level of 5OdBA. Industrial waste (fueling, lubricants spills...) may caused when the substation was defected. However, in design and installation stage a stagnated tank to dispose waste material would be built. Industrial waste therefore shall not spill or leaked out to surrounding areas. As the project comprises 22 newly built substations, and the new transformers, disconnecting equipment will not use oil insulation types of PCBs which was forbidden to use by the govemment from 1990 (PCBs is one of the 12 POPs Persistent organic Pollutants). These to be specified in the bidding documents of substation. According to analysis above, pollution of waste, dust, noise and vibration to surrounding areas of the project would not be a considerable impact if the construction will be managed properly. The impacts are of a short term nature and can be monitored against the national environmental standards. 2. Electric field impact on human and animal health: Electric power transmission line creates electromagnetic fields (EMFs). The strength of both electric and magnetic fields decrease with distance from transmission lines. It is assumed that health hazards may exist from EMFs. Also placement of low-slung lines or lines near human activities could increase the risk of electrocutions. According to Vietnamese standards on limits of industrial frequency electric field intensity and stipulations on the working environment regarding limits of electric field intensity for people working in the affected area in a day and night depend on the electric intensity as given in the following Table: Electric intensity (kv/m) < <E<25 >25 Permissible working time per day unlimited 8 4,25 3 2,2 1,33 0,8 0,5 1/6 0 and night (h) 36

35 EFFICE'lNCY IMPROVEMENTI OF' 110KV DISTRIKBUTI'ON NETWORK PROJECT'I NORTHERN VIETNAMl Thus, the electric field affected area is the area with the power frequency electric field intensity of > 5kV/m. The project transmission lines shall be designed following Vietnamese standards that minimize such risks. The height from conductor to ground is at least 6m (out of residential areas) and 7m within residential areas such as Do Luong-Tuong Duong, Thieu Yen-Ba Thuoc, Thai Binh-Kien Xuong, Bac Giang-Luc Ngan, Lao Kai-Phong Tho, Yen Bai-Nghia Lo T/L and Phu Yen branch. For any structure under the line routes, the maximum electric field under these I lokv T/L is around 2.79 kv/m. Working time per day and night therefore could be unlimited. Affected electric field is classified as below: Distance from conductor to affected area Electric field intensity(kv/m) (mn) 3 4, Basing on these above analysis and data, the electric field caused by the project would not affect human's health in the area within line ROW. 3. Impact on workers' safety and health: In the construction phase, worker may face some hazard conditions of accidents such as electric cutting, trauma... Besides, as a specific project, workers shall live permanently period of time in camps while implementing construction. This may cause disease: malaria, typhoid fever, diarrhea and other disease infected from drinking water and food. At the same time, opportunities for the mosquito species acting as mean of transmitting diseases may increase. 1II. IMPACT ON TELECOMMUNICATION SYSTEM, ON LANDSCAPE AND HISTORICAL RESER VES AND OTHERS On telecommunication svstems Telecom-imunication projects including: - Communication lines going closed to, crossing or along the 1 lokv T/L - Audio frequency, PLC telephone lines going closed or along the T/L The impact may jam broadcasting station and cause hazardous conditions due to I phase short -circuit current occurred on 11 OkV T/L. However, the data survey during investigation and design stage shows that there's only I IOkV Yen Bai -Nghia Lo T/L (portion along National Road No. 134 ) which is paralleled with communication bare cable and over head cable belonging to Yen Bai province post office. Nga Ba Khe-Nghia Lo communication line portion might be affected dunrng operation stage. I IOkV T/L and II OkV substations of the remaining subprojects were designed far from telecommunication projects. Other inter-district and intervillage communication lines are not very important that T/L was designed to cross or closed to few times. Nevertheless, the lengths of portions to be crossed are quite short that impact of electric field would be insignificant. Impact on landscape and historical reserves. The project traverses areas of different localities. Thus, the impact on the lands, army sites, airports, historical reserves, pagodas, etc have been considered in the investigation and-, 37

36 EFFICIENCY IMPROVEMENT OF I 10KV DISTRIBUTION NETWORK PROJECT NORTHERN VIETNAM design stage. This is criteria for line route selection which the 22 subprojects were applied to avoid such impacts. During investigation and selection stage of line route, there's only 110kV Bac Giang-Luc Ngan T/L that traverses army site belonging to Army crops No. 2. The TIL also traverses temple (former Buom market), Thuong Lam pagoda of Thanh Lam commune-luc Nam district at G8 position which were recognized as historical reserves. The T/L traverse former Binh Noi communal house, Noi Bang historal reserves at G32 position. Agreement with the concerned government agencies and the local NGOs have been reached with regard to the selected route lines. Records of the consultation meetings are provided in Annex 6. Impact on safety of explosion and fire The project covers large area in locations that would not be able to avoid war vestiges such as: unexploded bombs, mines...within ROW. This has been carefully considered during investigation, design, line route selection and construction stages so that negative impacts on human and environment would be minimized. Mine clearance in the places which were heavily affected by the war, will be carried out before the construction begins. Explosive substances will not be used in construction. The construction method to be used is excavation and simple instruments. In order to avoid fire, workers are not allowed to use forest trees or other material from forest in cooking or heating purposes. All substations shall equipped fire protection equipment. Conclusion: Construction of the project will result in number of different environment impacts, which depend on construction sites. Besides, even impacts on each factor of environment also depend on construction sites. In order to clarify the environment impacts, construction sites should be classified as follow: - 1st Location; in rice, crop fields. - 2nd Location: in hills, unused land,, land belonging to People Committee. - 3rd Location: in industrial zones, near national road. 38

39 EFFICIENCY IMPROVEMENT OF I 10KV DISTRIBUTION NETWORK PROJECT NORTHERN VIETNAM CHAPTER VI MITIGATION MEASURES Mitigation measures to reduce the project impacts are to be carried out in 3 stages, design, construction and operation. I. IN DESIGN STAGE: In the design phase, the alternatives for each component should be considered and selected to ensure they have the lowest impacts on ecosystem. The methods to reduce and mitigate the negative impacts should also be developed. For 110 kv transmission lines With the ecosvstem The selection of line routes should avoid tree cutting as much as possible. According to Law on Forest Protection of Vietnam, tree cutting, which affects environment, is strictly under control. Thus the selection should try to avoid dense forests, natural forests with high ecological values or reserved areas. The selected line routes in fact traverse only secondary forests or newly planted ones which have low ecological and economical value. For example two sub-projects in Do Luong - Tuong Duong and Phu Yen, line route was selected and designed so that it do not to traverse or cross natural forests and reserved sites in the areas. With residential area and safety issues: The optimal routes have been considered to avoid houses. For those unavoidably traversing residential plots, mitigation measures include increasing towers height, making numerous small angles to avoid houses and structures. Technical measures have been selected to ensure minimum impacts on houses and structures as well as safety to local residents. The solution include reasonable spans, special technical options for towers, arms, guys, foundations at locations that have risk of rockfall or erosion. With telecommunication lines: There is no impact on the telecom lines as line routes are designed in accordance with regulations and criteria of Degree No. 54 on power network row and Degree No.39 on post office transmission line row. Moreover, the T/L rarely traverse or go closed to interdistrict and intercommune telecommunication lines. However, for subproject 110kV Yen Bai-Nghia Lo T/L running along national road No.134, there would be impact due to telecommunication bare conductor line belonging to Yen Bai Post office at Nga Ba Khe - Nghia Lo part. It is necessary to coordinate with Yen Bai post office to replace bare wire by a cable at crossing section and to design special mitigation measures such as to increase height of the towers to reduce impacts to the telecommunication systems. With army sites, airport, historical resorts. pagodas and other constructions: The survey shows that selected line routes of 110kV Bac Giang - Luc Ngan T/L would traverse part of army site belonging to Army crops No.2. Power Project Management Board has discussed and got agreement on the line route with the affected organization. However-. 41

40 jefficiency IMPROVEMENT OF I IOKV DISTRIBUTION NETWORK PROJECT NORTHERNl VIETNAMl additional coordination with General Office of Arrmy Corps no.2 will required during site clearance and construction. The line routes could also traverse temple (forrner Buom market), Thuong Lam pagoda of Thanh Lam cornmune-luc Nam district at G8 position which were recognized as historical reserves. The T/L could traverse former Binh Noi communal house, Noi Bang historical reserves (on which war of resistance against Nguyen enemy in 18 I' century of Tran generation took place) at G32 position. To avoid these impacts, numerous small angles will be made during design stage. With impacts on landscape Line routes may affect sight seeing in the areas. Mitigation measures therefore should be considered and applied based specific conditions of different locations and cases. Following principles would be applied: - The line routes should avoid parks, reserved sites, and areas that have historical and architectural value. The routes should be hidden as much as possible. - T/L should be located in areas where impacts on landscape are least. - Avoid T/L running parallel with high ways or public entertainment areas. With the former war remnants.' During selection of line routes or substation sites, one of the highetst concems to avoid former war consequences such as: bombs, mines, etc. which could be in the ROW and in substation location. 2. For llokvsubstations 110/35/22kV substations of the project were designed mainly out door substation type. I10kV substations land acquisition is accounted for about m 2. All substation sites were selected to be located in land for agriculture, waste land, land in industrial zones and in land far from residential areas, there would not be impact on residential or protected areas. The substations were separated with outside by surrounding fences to ensure safety operation and avoid hazardous conditions to human and animal passing by. However, fueling and lubricants spills from substations may occur during operation. Absorb tanks will be included in the designs of substations with large capacity. All fuel, lubricants leaking and raining water therefore would be absorbed and treated before draining out. Impact on environment would be mitigated as fuel, lubricants leaking were split from water. Latrine system also designed to be built within substation sites to avoid pollution to surrounding areas. Fire, exploitation protective equipment and prevention methods, which are consulted and agreed with Fire Prevention Police Office, will be included in design stage of substation. Transformers, disconnecting equipment will not use electric isolation oil PCB type as PCB substance may cause cancer disease. This will be specified in the bidding document for supplying of transformer. Substations' connecting circuit diagrams were designed to be include protection equipment: + Drop-out fuse on transformner's MV side for short circuit and over current protection +Circuit breaker on LV side for short circuit and overcurrent protection + Sure arresters for over voltage wave protection Thanks to protection automatic equipment systems, power networks' fails during operation have been quickly eliminated, ensuring security, mitigating potential dangers to people in the area. Summary of mitigation measures during design phase is provided in the following table: 42

41 VIETNAMl Potential Impact Mitigating Measures 1)110kV Transmission Lines - Impacts on ecological system: trees - Line routes selected and designed to avoid natural and cutting, deforestation (natural and planted forests; Limit deforestation due to cutting of trees planted forests) that have economical or ecological value; replant trees as much as number of trees to be cut down (mechanical methods strictly forbidden; it is encouraged to use simple tools for trees cutting) -Impact on residential areas: Line routes may traverse houses and other constructors; noise disturbance - Carefully and properly calculated line routes to avoid houses and other structures; increase tower length; designed routes turning frequently to minimize number of houses to be traversed by line routes (there's no house to be traversed); manufacturers are requested to design equipment with maximum noise level when operating not exceed permitted noise level standards - Impact on communication line system - Comply with network safety regulations and articles and other broadcasting related means: stipulated in Degree No. 54 on safety of T/L may traverse or cross these systems. telecommunication transmission lines; Select line routes far from communication line system or minimize number of times crossing or traverse these systems; coordinate with Provincial Post Offices to cables the communication line system in crossing sections; calculate and prepare method to avoid jam or affection to communication line and other broadcasting mean systems. - Impact on landscape, army site, - Coordinate and agree with local authorities on locations historical sites, airport, reversed areas... have T/L traverse through; adjust design to avoid historical and cultural sites, reserved areas... -Impact on sight seeing of the - Hide T/L in side forests; avoid parks, public sites or high landscape that has T/L traversed through ways in order to hide T/L as much as possible; design TIL run along national roads, rail ways... 1I. DURING CONSTRUCTION STAGE: A. 110kV transmission line: 1. Construction arrangement: The construction plan will be optimized regarding implementation schedule for each task to reduce temporary occupation of land and impacts on environment. In addition, to minimize impacts on agricultural production caused by ROW and temporary occupation of land, construction should start after harvests. Line construction, tree cutting, site clearance, foundation works, material transportation, cable stringing... will cause certain impacts on environment. It is necessary to implement the following specific mitigation methods: Tree cutting, ROW clearance: Clearing methods should be selected to minimize impact of tree cutting and soil erosion. In Vietnam, the use of herbicide is very restricted and normally not used for this kind of projects. 43

42 EFFICIENCY IMPROVEMENT OF 110KV DISTRIBUTION NETWORK PROJECT NORTHERN VIETNAM According to the current practice, tree cutting will be selective using mechanical means so that the impacts will be minimised. This method will strictly be applied for the components where transmission lines have to traverse forests. After the construction is completed, trees with appropriate height and grass will be replanted again in the foundation area and in the temporarily used areas for construction to restore original environment and reduce future soil erosion. Temporary road requiredfor construction: Selection of temporary roads during construction progress was considered during design and will reconfirm before implementation. In order to avoid potential negative impacts on environments, it is necessary to implement the following main mitigation methods: - Access roads should avoid sensitive areas. Consultation and agreement with local authority on the selection of access road and proposed mitigation measures are to be done before construction start. - To avoid run off and sedimentation from grading for access road and alteration of hydrological pattem, the design and construction of assess road must be examined carefully and an appropriate water drainage system will be considered and constructed when needed to avoid water spreading causing soil erosion. Sediment traps are to be installed where required to control sedimentation. - After construction completion, most of access roads would be demolished. It is necessary to applied measures for road restoration such as clearing and levelling the road surface, replanting grass and trees to restore the original status. All the measures will be included in the responsibilities of contractors. Safety during construction - Equipment and material or heavy equipment transportation must be handled by special transportation vehicles which should be checked before use in compliance with transportation security regulation. - During foundation and tower works, safety regulations will be strictly followed. As tower work is a manual process, any remaining sand and broken stones must be cleared so that thre are no impacts on future cultivations. - Before starting works on foundations, it is necessary to coordinate with relevant agencies to identify and avoid damage on water pipes, postal cables or power cables. - Implementing safety methods as regulated during tower erection phase - Facilities and equipment must be careful checked in terns of quality and quantity before use. Construction leader needs to appoint a person responsible for security supervision. This person will check production equipment, labor protection facilities and remind every one for care. 2. Worker camps Many camps need to be established due to characteristics of line construction. The appropriate location should be close to residential areas so that it is easier to get food, water provisions, as well as communication facilities. However, the sites for camps should not interfere the norrmal life of local people and need to be selected in agreement and consultation with local authority. However, in some cases the construction will be carried out in difficult areas without local population, temporary camps will be establish near the line and the works there will be optimized with limited number of workers as possible. During the construction, workers' health will be protected in accordance with specific regulation on health and hygiene methods. Each independent work unit will appoint one 44

43 ENVIRONMENTAL IMPACT ASSESSNMENT EFFICIENCY IMPROVEMENT OF 110KV DISTRIBUTION NETWORK PROJECT NORTHERN VIETNAM personnel who has health competence to take care issues such as helping, medical care, preventing and treating disease: typhoid, malaria, diarrhea, and other transmitted disease. Wastes from camps will be controlled and will be disposed to places as agreed with local authority to avoid impacts to environment and to local residents. Construction workers are prohibited to use trees or other materials from forest for cooking or heating. 4. Pollution caused by noise Construction may create dust, noise and vibration, caused by transportation truck and construction equipment. To reduce pollution of dusts, for construction close to residential areas, load truck transporting material on roads will be requested to be covered. Night works will be carefully considered in order to reduce noise to local residents. As the voltage level s is mainly designed at 110kv, 35kV, 22kV, noise caused by arcing flashover in the light rain or humid condition are insignificant, so will not be considered. Generally, in construction phase, with appropriate mitigation measures applied the project negative impacts would be low potential impacts. B. 110kV Substations In order to avoid and eliminate pollution during site clearance and material transportation, specific vehicles, trucks covered or land watering methods would be used. Noise caused by construction machines may affect human activities in the surrounding areas. All construction machines should be checked before use in compliance with operation security regulation. In case of machine causing high level noise, night shift should be limited (for locations near school) or forbidden (for locations near hospital). Rubbish and construction material waste must be disposed to appropriate places agreed earlier with local authorities in order to ensure sanitation and avoid pollute local water and land. Water draining system is to be built in compliance with industrial hygienic standards. In order to avoid interruption of season crops, working schedule in locations within agricultural areas should be selected suitably. If there is any canal belong to the local irrigation system located on substation areas, it is necessary to rebuild the irrigation system completely before site clearance. III. DURING OPERATION STAGE: During operation, the provincial power service under PCI will take over the environmental management. ROWManagement According to the project management scheme, Provincial Power Services shall examine and supervise land utilization within ROW in provinces. Violations of land, trees within ROW areas must be checked and prevented immediately. Tree cutting to ensure safety regulation will be periodically. Tree cutting will be done by hand to reduce impacts on environment. The use of herbicide is prohibited. Local authorities, organizations and landowners shall supervise tree cutting. Access Roads Although many access roads for construction will be removed after project completion, there remain some access roads that are required for inspection, reparation and periodical maintenance purposes. 45

44 EFFICIENCY IMPROVEMENT OF 110KV DISTRIBUTION NETWORK PROJECT NORTHERN VIETNAM For subprojects IIOkV Do Luong-Tuong Duong T/L, IOkV Phu Yen branch, IIOkV Cho Roe, there are few temporary roads traversing secondary forest. It is required to get agreements with local authorities and provincial agriculture agencies on management of the road to avoid deforestation. Similarly is required for subprojects I1OkV Lao Cai-Phong Tho, Tuyen Quang-Chiem Hoa T/L and 1OkV Ham Yen, Phu Yen, Quang Ha where there are some branches of access road traversing planted forests. In addition, grass and trees must be planted in order to remain vegetation and avoid risk of erosion or landslides. Pollution To avoid oil or lubricant spillage, the substations were designed with suitable oil pit and oil tank. Regulations on monitoring and regular checking for possible oil spillage is required. Used oil should be disposed according to the environment regulations. Fire hazard. The substation is designed and equipped with fire detection and prevention according to Govemment regulations. All workers will be trained for fire prevention and fighting. There shall be regular monitoring for compliance with fire prevention regulations. 46

Analysis of alternative selection for the 110kV Tinh Gia substation and 110kV transmission line Two alternatives for the substation are considered. The first site is located in the land of Chuot Chu mountain, Tinh Hai commune. The second site is located in the land of 74 mountain, Mai Lam commune. Associated with the substation, there is a connection line of 11OkV of about 6.5km in alternative 1 and about 6.4 km in altemative 2. Therefore total permanent land acquisition and temporary land acquisition of altemative I are larger than alternative 2 0. Ikm but the terrain of transmission line in 2 altematives are different as follows: - Altemative 1: The line route traverses the cultivated land. Number of angles is small. That is a terrain favourable to construct and control. - Altemative 2: The line route goes past the range after range mountains, the number of angles is large. It is also not convenience for construction and transport. The impacts on the existing environment in the mountains are higher than the first option.

56 ENVIRONMENTAL INIPACT ASSESSMENT EFFICIENCY IMPROVEMENT OF 110KV DISTRIBUTION NETWORK PROJECT NORTHERN VIETNAM CHAPTER IX PUBLIC CONSULTATION AND INFORMATION DISSEMINATION World Bank (the Bank) policy regarding community involvement provided in detail in the WB Public disclosure Policy BP It is summarized as follows: It requires that the borrower to publicly solicit, hear and consider the concerns of the local community, other affected groups and local NGOs (non-governmental organizations) and to fully incorporate into the design and implementation of the project and the Environmental Assessment (EA). The rationale for consideration and incorporation of the concerns affected parties is to assure community acceptance and enhance the viability of the project. The Bank has found that where such views have been successfully incorporated into the design and plan of implementation, the projects are more likely to be successful. The Bank has not found community participation to be an impediment to project execution. On the contrary, projects in which affected parties views have been excluded are more likely to suffer from delay and issues resulting from community resistance. Vietnam is a socialist country. The State is detertnined by the fundamental principle "of people, from people and for people". The democratic approach to the social management of GOV is expressed in the basic principle of principle "people know, people discuss and people control" all activities of the Government. To avoid negative impacts on project affected people. Governmental Decree N 1 75/CP issued on 18 April 1994 requires that all projects in the development of industry: energy, transport, water resource, agriculture, etc. should conduct a compliant EIA study meeting the requirements of the environmental management authorities and the contents of ETA reports include predicted impacts and mitigation measures must be discussed with the PAP. The PAPs will be provided with access to EIA and project summary so that they can submit their comments and concerns to the project proponents through their authorized representatives, e.g. governmental agencies (the people Committee. People Council) and/or socio-political organizations (Fatherland Front, Farmers Association, Women Union etc.) or non-governmental organizations (e.g. Vietnam Association for the Conservation of the Nature and Environment, Biological Association, Economic Association, Foresters Association etc.). These organizations should collect all comments from the local people and send them to the environmental management authorities (DOSTE at provincial level or MOSTE at central level) or even to provincial People's Council or National Assembly. During the environmental review process, all comments and requirements of the PAP should be discussed and conclusions reported to the project proponents, so that the project can develop proper alternatives and implement measures for mitigation of the negative impacts. The, project will receive an investment license, only after appropriate modification of location, design, capacity and/or technology of the project to meet the requirement of environmental protection and resettlement. Involving affected people, especially the poor, often requires additional expenditures. The costs include travel and subsistence for attendance at meetings. Translation and expert advice that the community needs to help to formulate a response to the proposal, etc. Such costs should be systematically budgeted. The EA team must 58

57 EFFICIENCY IMPROVEMENT OF 110KV DISTRIBUTION NETWORK PROJECT NORTHERN VIETNAM ensure that issues raised in affected communities are communicated to the other participants in the EA process, including various public agencies and NGOs that may be in the larger process of public consultation. As the EA proceeds, the people in the affected area should be kept informed routinely and systematically. Written material must be translated into local languages. Where many are unable to read, oral discussion and visual presentations sessions (often, by the resident social promoters or facilitators) should be used. Throughout the EA process, the project agency should continue seeking views from and providing feedback to the affected community. Contents of Public Consultation meetings. - Participants will be informed about major technical and environmental issued of the project and mitigation measures. - In the meetings all questions of PAPs should be addressed, all recommendations and concerns of PAPs and PCs should be recorded. - List of participant should be noted with their signatures. - The use of video cameras, photo-camera and recorders is recommended. Materials to be presented in the meetings. The Consultants will present the following materials: - Booklet/summery of pre F/S Report and EIA Report - Maps of the project site - Figures, tables, photos, pictures, etc. presenting the project activities. 1. Aims of public consultation and information dissemination Inforrnation dissemination to, consultation with and participation of affected people and involved agencies (i) reduce the potential for conflicts, (ii) minimize the risk of project delays, and (iii) enable the project to design the resettlement and rehabilitation program as a comprehensive development program to fit the needs and priorities of the affected people, thereby maximizing the economic and social benefits of the project investment. Aims of public consultation and information dissemination are: - Share all project descriptions, components, purposes as well as project negative impacts on environment and restoration and mitigation measures. - Collect information on project environment, local people's concem on project in general and on environmental aspects in particular. - Find co-ordination and participation of local people in realising impact risks as well as supervising the project activities. - Reduce probability for social conflicts, - Reduce risk for project delay. 59

58 EFFICIENCY IMPROVEMENT OF 110KV DISTRIBUTION NETWORK PROJECT NORTHERN VIETNAM - Help to establish a comprehensive environment management plan and thus, maximise the project socio-economic benefit. - To ensure transparency in all activities related to land acquisition, environmental impacts and mitigation measures. Public consultation and information dissemination was scheduled for 2 stages: project preparation and project implementation. Refer to the meeting list attached for details. 2. Public consultation and information dissemination during project preparation stage: During project preparation stage, the following activities were carried out sequentially: route. Phase I-Activity 1: Information & discussion with local authorities on the line After studying maps and visiting the site, Consultation Units had envisaged a preliminary route on 1/50,000 scale map. This map was sent to all locations passed by the line and relevant local authorities. The local authorities have agreed on the project line routes. This activity was carried out in 2nd quarter/2002 Phase I - Activity 2: Impact survey and statistics Based on the agreed line route, survey teams had realized the route at site, made the piling and coordinated with the commune officials to make a list of PAPs' affected land and crops. The socio-economic survey forms were delivered to affected households (for each corranune). This activity was carried out in 3rd quarter/2002. Phase I - Activity 3: Meetings with PAPs When the survey finished, Consultation Units in coordination with the commune officials held meetings with PAPs having land in the line ROW and with village representatives. In these meetings, Consultation Units officials inforned the participants of the project purposes; presented the project impacts on land and crops in detail; introduce the principles and policies of compensation and advised people not to build new structures in the line ROW. PAPs were consulted on the entitlement- policy and the compensation in cash had been accepted. Phase I - Activity 4: Meetings with the concerned PPCs After working with the communes, in 6/2001 Consultation Units had sent missions to work with the provincial functional agencies such as Financial and pricing service, Planning and investment service, Agriculture and rural development service, DOSTE, etc. and make the project purposes clear to PPCs; at the same time discuss with local officials on the aims and principles of ground clearance, on the proposed policies of EIA, legal and illegal issue and the local organization working on resettlement and compensation; collect the local compensation rates for land and crops. Records of the meetings with PPCs on route lines are summaried in Annex 5. Written agreement on the selected route lines are attached Phase I - Activity 5: Consultation on EIA 60

59 EFFICIENCY IMPROVEMENT OF I 10KV DISTRIBUTION NETWORK PROJECT NORTHERN VIETNAM Basing on the survey result, the Consultation Units of the Power network project management board has prepared draft EIA to submit to EVN, WB and concerned PPCs for revision. In January, 2002, Meetings with PAPs, NGOs and local authorities in the project sites were carried out for all subprojects to get feedback and comments on the draft ELA. No major comments on environmental issues and findings of the EIA has been raised during the public consultation process. In general, the attendants of the meetings have agreed on the mitigation measures proposed in the ETA. Records of the public disclosure meetings provided in Annex 6. Phase I - Activity 6: EIA review and appraisal In 11-12/2001, Consultation Units had sent missions to work with the district people's committees, DOSTEs on draft EIA. The revised ETA shall be submitted to WB for approval. PCI will get environmental certificates from the relative DOSTEs. This shall be legal basis for EIA implementation. After preparation, the draft ETA report has been made available at DOSTEs from January 2002 for public display. 3. Public consultation and information dissemination during project implementation stage: Public consultation and information dissemination during project implementation is of great importance as the project impacts on the environrnent and people at the stage would be worst. The following infornation campaign should be carried out: * General description of project: Right after signing of credit agreement and preparation of project commencement, the first task for PMB is to held meetings with involved PPCs, DPCs so as to inform them of the project policy. * Information on EIA: Another information campaign on environment impact mitigation shall also be lounged beside the information campaign on RAP, the campaign shall include: 1. Notification on local means of communication: PNPMB shall coordinate with the local authorities in notifying on local newspapers and television channel about project general informnation such as: project implementation schedule, project components, information on project impacts on local people and mitigation measures.. 2. Environment information booklet An environment information booklet (EEB) on impact and mitigation measures will be prepared basing on the approved ETA report. The booklets will be displayed at offices of involved commune and district people's committees, and will be distributed to local unions such as farmers' association, women's association, all heads of project villages, all PAPs in the project area in the initial duration of the implementation stage of the project. The EIB contents are outlined below: 61

Reporting system A proposal on environmental protection and impact mitigation measures to be applied will be prepared by the contractor and sent to PPMB of PCI for ratifying before construction. The proposal should be included safety of persons associated with the works and also the public, during construction period. Main points of the proposal are as following: - Mitigation measures to be taken on and off site avoiding damage or nuisance to persons or to property arising. - Safety methods to maintain conditions of safety for all persons entitled to be on site and - Provision and maintenance of all lights, guards, fencing, warning signs and watching for protection of the works and other property and for the safety and convenience of the public. Construction Contractor will provide monthly reports to the PNPMB in which describing all the environmental mitigation and protection measures carried out in the month. Monthly report also applies to the Independent Monitoring Contractor and Provinces' Power Services for their part of mitigating and monitoring activities. In case of accident or endangerment of environment, an unusual report must be done immediately and sent to PNPMB, PPCs, DOSTEs, DPCs for consideration and settlement. Monitoring Contractor will be selected before construction phase starts. Monitoring Contractor will monitor environment quality (air, water and soil quality, noise levels and equipment supply) through those report monthly to the PNPMB and the WB. These reports will encompass list and explanation of all undertaken activities at the site and results of the field research, as well as recommendations for future field activities and protection measures. Basing on received data from these monthly reports, PPMB will prepare quarterly Environment Monitoring Reports for submission to the PC 1 and the WB for consideration. The quarterly report shall resume information gathered at the field and evaluate effectiveness of the mitigation program in the light of monitored parameters. In additional, the report will concentrate on possible future mitigation and monitoring activities that could be utilized to assure better quality of the environment. An annual Environmental Report sent to EVN and the WB will be made by the PCI in which summarizes the environmental protection measures implemented, problems encountered, actions taken to resolve environmental problems and results of environmental monitoring. PPMB under instruction of PCI will have the authority to spend, shutdown change operations according to recommendation of the DOTEs. This will be the case if environment conditions of the site clearance or construction included in project are not in accordance with environmental standards and regulations or if works are not perfumed - 72

71 EFFICIENCY IMPROVEMENT OF I 10KV DISTRIBUTION NETWORK PROJECT NORTHERN VIETNAM according to technical specifications and contract requirements related to the environment. This will be proved by Monitoring Contractor reports to DOSTEs. PPMB are authorized to supervise and check all expenditures referring to mitigation and monitoring activities through recommendation of Environmental Unit after ratified by the PPCs. Environment Inspection Department of the MOSTE will have the authority for immediate suspension of works if performance is not in accidence with environmental standards and regulations. Inspection will then inform PCI, PNPMB about suspension and order to proceed according to their directive. Institutional arrangements flow chart is enclosed with all briefly relations presented as controlling and reporting activities. During implementation of this Project public has the right to participate either directly or indirectly which introduces the possibility to present its interests and opinion in process of decision making. In order to reach the best option during this process, state should enable for each individual to get appropriate knowledge connected with basic relation between nature and human health, activities with harmful influence on nature and importance resulting from it. Public or each individual will be allowed to bring legal action at competent court if it considers that its claim for participation or information is ignored, groundlessly refused or provided information is inadequate. 73
