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 Southern Vietnam implemented by the Power Company No2. 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 Estimating costs of the proposed mitigation measures. Methodology The method applied in the report is based on environmental checklist Based on the guidance on EIA 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. EIA OF PROJECTS MANAGED BY PC2 4 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION CHAPTER II PROJECT DESCRIPTION 1. NAME OF PROJECT Efficiency Improvement of 110 kV Distribution Network in Southern Vietnam 2. IMPLEMENTING AGENCIES Investor: Power Company No2 Project Manager: Power Company No2 Consulting company: Power Engineering Consulting Company No 3 3. PROJECT OBJECTIVES Power Company No2 is a independent accounting utility of the Electricity of Vietnam. PC2 was established in 1995. PC 2 is responsible for supplying electricity for 22 million people living in 20 provinces in Southern Vietnam except Ho Chi Minh city and Dong Nai province. Over the past 5 years 1996-2000, the power demand in PC2 areas has been increasing steadily at the average rate of 18.5%. The fastest growing demand has been seen in the residential sector with average growth of 21% following by industrial sector with an average growth rate of 17.5% per year. Total sales of electricity in 2001 was 4,669 GWh with distribution losses of 11.5% in 2001. It is forecasted that during 2001-2005 the demand of the whole region will grow at 9.6 % reaching 7,387 GWh in 2005. To meet the fast growing demand of the region, PC2 plans to expand the existing distribution network, especially at the 110 kV voltage level, which is the bottleneck of the distribution system given the recent extensive expansion of the MV and LV distribution network according to the rural electrification program. The Efficiency Improvement of 110kV Distribution Network in Southern Vietnam project is to construct + Fifteen 110kV substations with total installed capacity of 405 MVA, + 15.771 km of double-circuit 110kV TL which are connecting taps from the national grid to the above mentioned substation) + Four 110 kV single-circuit transmission lines with total length of 81.797 km. in 11 provinces of Binh Thuan, Ninh Thuan, Binh Phuoc, Binh Duong, Ba Ria - Vung Tau, Kien Giang, Ca Mau, Bac Lieu, Dong Thap, Soc Trang and Vinh Long. The project will: (i)provide additional transformer capacity and eliminate the bottleneck of the transmission network to serve the growing demand of Southern Vietnam; (ii) to EIA OF PROJECTS MANAGED BY PC2 5 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION reduce the transmission losses of Southern distribution network; and (iii) increase reliability of the power supply to the region. Total project cost is US$ 36.7 million with IDA credit of US$22.33 million. 4. DESCRIPTION OF THE PROJECT COMPONENT The technical specification of each project component are provided in Table 2. 1.

ENVIRONMENTAL MANAGEMENT Presently, the responsibility on environmental management is arranged as follows: Ministry of Science - Technology and Environment (MOSTE) of Vietnam is the central government environmental management, the organization is responsible for the guidance for the preparation, appraisal and supervision of the implementation of EIA report for the investment projects. This project is classified as the project of type II that is required to have environmental registration for compliance with environmental standards. The project is required to prepare an environmental impacts report. Department of Science - Technology and Environment (DOSTE) is responsible on environment in each province. Although administratively under Provincial People Committee, on technical issues, all DOSTEs reports to MOSTE. DOSTEs are assigned by the MOSTE to inspect, supervise on implement ratification of EIA reports, environmental standard registration forms and environmental protection regulations in operation in its field of action, and to treat according to the law with violating cases.After receiving environmental standard documents of the project of EIA OF PROJECTS MANAGED BY PC2 I UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION type 11, the DOSTE is going to examine and to issue a environmental standard certificate. In addition, at district level, there is a division under DPC in charge of environment management. This division reports to DOSTE on technical aspects. EVN is responsible for supervising and guiding environmental protection in power sector as a whole. There is an centre within EVN directly in charge of environmental management. PC2 is project investor who is directly responsible for environment managmeent of the project during its lifetime. During project preparation and construction, PC2 has authorized its Power Project Management Board of PC2 (PPMB of PC2)to be in charge of project management. After commissioning, the project will be handed over to the provincial power service department (PPSD), where the project is located. The PPSD will be in charge of environmental management during operation period. For each project component, a consulting company is appointed for preparation of all project documents such as FS, EIA and RAP. The selected consulting companies are responsible for identifying environmental impacts during project lifetime and measures and implementation plan to be applied to mitigate these impacts. PC2 is responsible for submission of environmental registration for the project to the related DOSTEs. In the construction phase, groups of supervisors will be set up, these are contructor supervisor, investor supervisor and designer supervisor. These supervisors are founded by relevant organization and also have the responsibility of environmental monitor. PC2 is responsible for environmental performance of the project under supervision of the concerned DOSTEs. During the operation phase, the provincial power service departments (PPSD) are responsible for environmental performance under supervision of the respective DOSTEs. Environmental monitoring data and reports on environmental supervision will be submitted by the PPSD to PC2 and respective DOSTEs. EIA OF PROJECTS MANAGED BY PC2 12 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION CHAPTER IV BASELINE DATA 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 domrinant land forms. The project components are located in 3 regions namely Mekong Delta, South Central Coast and North East of Mekong. Details of natural and socio economic conditions of project involved provinces are provided in Table 4 Mekong Delta: (Ca Mau, Soc Trang, Dong Thap, Vinh Long, Bac Lieu, Kien Giang) The region is the largest delta of Vietnam and is the most important rice production center of the country. Mekong delta characterized by tropical climate with rainfall level of 2000 mm per year which comes later in June and ends in November. Soils are mostly alluvial but there are extensive areas of acid sulfate and saline soils which can be developed only with special care. The region has low susceptibility to erosion. North East of Mekong:(Baria Vung Tau, Binh Phuoc, Binh Duong) The region has tropical climate with the rainfall from 2000 mm to 2200 mm from April to October. The dry season is pleasantly col. The yellow-red and degraded grey soils that predominate are acidic and of low fertility. 98 of the North East Mekong has low susceptibility to deterioration. South Central Coast: (Binh Thuan, Ninh Thuan) The region is characterized by a very low rainfall of 700 mm per year, high temperature and prolonged dry season similar to North Central region. Average yellow-red soils dominate the uplands and alluvium is common to the valleys. Despite rolling topography, low rainfall means that 50 % of this region has low susceptibility to deterioration. Natural conditions of each sub project area are described in Table 4.

IMPACTS 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 relatively populated areas such as in Ngai Giao, Thoi Binh, Dai Ngai and Tan Uyen projects 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 as in Binh Thuan and Ninh Thuan or where the foundation morphology is not very strong. It should be noted that due to low level of susceptibility to deterioration of Southern Vietnam in general, erosion caused by the project is insignificant. EIA OF PROJECTS MANAGED BY PC2 16 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION Noise caused by arcing flashover in rains or very humid condition will not be considered as it is considerably small (<1OdB 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 to 3m, if using simple tools, the construction would not affect underground resources. 2. IMPACTS ON BIOLOGY ENVIRONMENT AND ECOSYSTEM 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. Effect on clearing and control of vegetation in ROW 2~~~~~~~~~~~~~~~~~~~~~~ The project ROW has occupied totally 1,297,159 m2, in which there are 1,009,278 m of annual crop fields (such as rice, cassava); 93,420 m2 of perennial crops fields (such as cashew, coffee, fruit trees, rubbers etc.); and 187,385 m2 of fish and shrimp farms. Details are provided in Table 5.1. According to Vietnamese standards on safety of ROW network, for 1 10kV 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. Therefore, all trees of or would be higher than 4m in the ROW must be cut down. The trees that would be higher than 4m height shall not permitted to plant within the ROW. During operation, all trees higher than the limit also must be cut down as well. There are 17,950 trees to be cut in the project, of which there are 2,224 cashew trees, 3369 rubber trees, 2,315 bamboos, 2673 eucalyptus, 1,634 coconut trees, 833 coffee trees; 2,533 pepper trees and 2,369 long-term fruit trees (mango, saboche, longan, etc.). This would have some impacts on the biological values and ecological systems. The trees will be compensated at replacement costs. There's also impact on rice and crops within ROW during construction stage (tower transportation, conductor stringing, tower foundation...). There are 193,982 m2 paddy fields, 31,679 m2 of vegetable fields and 2,400 m2 of manioc fields that will be in the project ROW. However these impacts are only of temporary nature (with duration of fiom 3 to 6 months), which can be minimized if construction schedule is arranged after harvest and by optimizing construction time for areas with high impacts on crops. In this project, the substation site or transmission line routes are located or traversed mostly cultivation areas with paddy and other crops such as sugar cane, cashew, fruit trees. The project components do not traverse through protected areas, with natural primary forest or areas with high biodiversity. Although in Ca Mau and Ba Ria Vung Tau there are protected mangroves, the project components in these provinces do not traverse EIA OF PROJECTS MANAGED BY PC2 17 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION these sensitive areas. As such, impacts on local habitats and on ecological system is insignificant.

Total permanent land acquisition of the project is 96,269.7 m2, of which there are 63,845.4 m2 of annual crops, 13,596.5 m2 of perennial crop lands, 12,731.9 M2 of 2 aquaculture farms and 6,096 Mi of residential land. Statistics are provided in Table 5.2 and in the Annex. Land will be affected temporarily in foundation works, tower erection, conductor, earthwire pulling and stringing.and for construction of access road for material transport to the line route. As each component can be completed in 3÷ 6 months, the impacts will be on one crop time. EIA OF PROJECTS MANAGED BY PC2 20 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION The total temporary requisition of the project is 153,090 m2, of which 59,426 m2 is annual crops land; 18,935 m2 is perennial crops land ;73,257m2 is aquaculture farms and 1,472 m2 is residential land. 3. 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 110 kV T/L connected to substation may traverse houses. In order to avoid houses, the line route was designed to turn frequently with numerous small angles. However, the project still affect 100 houses, of which 98 are fully affected houses and 02 partly affected houses. Total demolished area is 4,777.9m2. 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 50 dBA, the permitted noise level. As the voltage levels are 110 kV, 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 50 dBA. 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 13 newly built substations, and the new transformers, disconnecting equipment, circuit breakers to be installed will not use oil insulation types of PCBs which was forbidden to use by the government from 1990 (PCBs is one of the 12 POPs Persistent Organic Pollutants). The requirement on PCBs is 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. EIA OF PROJECTS MANAGED BY PC2 21 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION 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) <5 5 8 10 12 15 18 20 202 Permissible working time unlimited 8 4,25 3 2,2 1,33 0,8 0,5 1/6 0 per day and night (h) _ .- I_ _ 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 Ngai Giao, Thoi Binh, Hong Ngu, Dai Ngai, Long Dat and Tan Uyen. For any structure under the line routes, the maximum electric field under these I IOkV 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 Electric field affected area (m) intensity(kV/m) 3 4.6 4 2.79 5 1.82 6 1.24 7 088 EIA OF PROJECTS MANAGED BY PC2 22 UPGRAOING 110KV SYS7EM FOR RURAL ELECTRIFICATION 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 shock etc... Besides, in some projects, workers have to live for some period of time in camps while implementing construction. This may cause disease such as malaria, typhoid fever, diarrhea and other diseases infected from lack of clean drinking water and food and from mosquitos. 5. IMPACT ON TELECOMMUNICATION SYSTEM, ON LANDSCAPE AND HISTORICAL RESERVES AND OTHERS On telecommunication svslems Telecommunication projects that may be affected include: - Communication lines that are going closed to, crossing or along the 110kV T/L - Audio frequency, PLC telephone lines that are going closed or along the T/L In the project, there is no wireless communicating constructions and telephone lines near the line routes. Impact on landscape and historical reserves: The project traverses areas of different localities. Thus, the impacts on the lands, army sites, airports, historical reserves, pagodas, etc have been considered in the investigation and design stage. To avoid such impacts is the criteria for line route and for substation site selection for the 15 subprojects . As a results, the transmission lines and substations were carefully selected so that there is no impacts on historical reserves or landscapes. Impact on safety of explosion and fire The project covers large area so that there could be war consequence such as: unexploded bombs, mines... within ROW and substation site which are not disarmed yet. This has been carefully considered and consulted with local authorities during investigation, design, line route selection and construction stages so that negative impacts on human and environment would be minimized. There is no areas within the project with risks of war consequences. The construction method to be used is excavation and with simple instruments. Explosive substances will not be used in construction, so that impacts on soils and underground water are not significant. There is a risk of fire in substations with electrical EIA OF PROJECTS MANAGED BY PC2 23 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION equipments and from cooking by construction workers. However, the risk will be controlled as all substations shall equipped fire protection equipment and there will be strict ban on the used of woods and other forestrall materials available locally in cooking by workers. EIA OF PROJECTS MANAGED BY PC2 24 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION CHAPTER VI MITIGATION MEASURES Mitigation measures to reduce the project impacts are to be carried out in 3 stages, design, construction and operation. 1. IN THE DESIGN PHASE For tranmission lines With the ecosystem 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 protected and reserved areas or natural forests with high ecological values. The selected line routes and substation sites have been selected with minimum impacts on tree cutting and do not traverse any reserved areas. In designing Binh Chuan-Tan Uyen line and Dai Ngai- Soc Trang line, the route are selected to minimize cutting rubber and fruit trees that predonunant in the areas. Selection of temporary roads during construction progress was also considered during design. To avoid potential negative impacts on environments, it is necessary to follow the principle that access roads should avoid sensitive areas. The selection of access road also to be preliminarily consulted and agreed with local authority during design period. The transformers and equipment for the project will not use PCBs as specified in design and bidding documents. 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 landslide or erosion. Special attention was given to projects in Binh Thuan, Ninh Thuan where the substations are to be build in slopping hills. Technical solutions iri the selection of line structure to overcome the negative affection of the project on environment and safety include: EIA OF PRWECTS MANAGED BY PC2 25 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION - Conductor: cross-section of conductor is chosen by economic current density is 1,lAJmm2 and calculated based on lirmited pressure regime with air temperature and highest internal loading capacity (wind). - tnsulator: is chosen according to current regulations. The area which is passed by the line route is far from sea, not to go through dusty and poison-gas area. Therefore the affection on atmosphere pollution with insulator is calculated at low-polluted level (IEC standards). Insulator of substation and line route is used with porcelain or tempered-glass insulator. Accessories is chosen to fit the size of conductor, insulator and to ensure the safe factor according to regulation. - Earthing: the substation and line route is earthed according to branch's procedures to ensure for safe operation as well as people at residential area. ± Pole, foundation: * Use galvanized steel tower on the whole of line route. * Use reinforced concrete foundation on the spot. The calculation and selection of solutions of line structure is based on climate condition in the current electric-equipped procedure TCN-19-84. ln design calculation, if the conductor arrangement on the poles which have the distance from conductor to the ground is calculated 8m for lowest and the other safety distance are carried out pursuant the norrn, the electric strength under conductor from heart of the line out has the much smaller value compared with the standard of WHO and norm promulgated by the branch is <5kV/m. Therefore, worker can work under the line route normally. With telecommunication lines: The line routes and substation locations selected in a way that there is no impact on the teleconmmunication sites or projects. With historical sites, pagodas and other cultural sites: The line routes and substation sites were carefully selected and designed in a way that the project will not affect any historical or valuable cultural sites. With 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: EIA OF PROJECTS MANAGED BY PC2 26 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION - 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. - TI/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 remnanis: During selection of line routes or substation sites, one of the highest concerns is to avoid locations with former war consequences such as: bombs, mines, etc.. 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. However, according to investigation, there is no areas in the project which needs to disarm bombs, nunes. For l lOkVsubstations 110/35/22kV substations of the project were designed mainly out door substation type. 110kV substations land acquisition is accounted for about 95.000m2. 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 enviromnent 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 transformer's MV side for short circuit and over current protection EIA OF PROJECTS MANAGED BY PC2 27 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION +Circuit breaker on LV side for short circuit and overcurrent protection + Surge 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 surrounding areas. 2. IN THE CONSTRUCTION STAGE The mitigation strategy in the construction stage includes: 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. According to the current practice, tree cutting will be selective using mechanical means so that the impacts will be mimnmised. 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: The selection of temporary roads during construction progress and proposed mitigation measures, considered during design stage will have to reconfirm before implementation and agreed with local authority before construction start. - To avoid run off and sedimentation from grading for access road and alteration of hydrological pattern, 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. EIA OF PROJECTS MANAGED BY PC2 28 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION 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 the 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 terms 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. 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 normal 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 lirmited 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 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. Pollution caused by noise, dust and vibration 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. Construction sites are to be watered regularly to reduce dust. EIA OF PROJECTS MANAGED BY PC2 29 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION 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. For 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. 3. DURING THE STAGE OF OPERATION During operation, Provincial Power Service Departments (PPS) will take over the environmental management for the project.. RO W Management According to the project management scheme, PPS shall examine and supervise land utilization within ROW in provinces. Violations of land, trees within ROW areas must be checked and prevented inmediately. 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. In the project there is no environmentally sensitive areas, so with access road, soil erosion should be checked and prevented. EIA OF PROJECTS MANAGED BY PC2 30 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION 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 Govermment regulations. All workers will be trained for fire prevention and fighting. There shall be regular monitoring for compliance with fire prevention regulations. EIA OF PROJECTS MANAGED BY PC2 31 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION CHAPTER VII ANALYSIS OF ALTERNATIVES During selection of line routes and substation location, the consulting companies have carefully studied different alternatives for each project on maps and at site and then carried out thorough investigation. For substation: Criteria for selection of substation sites are: - Closeness to load center; - Convenience to connect the substation to the existing network; - Lowest impacts on environment and local people; - In accordance with local planming and landscape. Therefore, there is only one suitable option for substations sites and no alternatives for substations are needed. The sites for sub-project of Luong Son, Chon Thanh, Phu Giao Giong Rieng, Ca Mau 2, Hong Dan, Ninh Hai, Bu Dang, Long Dat and Binh Minh subtations have been selected and agreed upon with the concerned Provincial People Committees. For Iransmission line: Two alternatives for the route lines are normnally considered for comparison for each sub-project. Generally, in the South, the considered alternatives have very similar environment. So the difference in environment impacts of compared options is not significant. So the routes with better technical characteristics, shorter with less ROW and less compensation on resettlement are normally selected. Criteria for route selection are as follow: - The route selected is as short as possible, the substation is suitably designed for minimum construction cost and land acquisition. - The transmission line should avoid concentrated residential and conservation areas by turnings. Though more turning angles means high cost, the compensation cost and delay would be less. - The transmission line should be as closed to the transportation roads as possible to facilitate material transport during construction and management and operation, meanwhile reduce land acquisition for access roads. EIA OF PROJECTS MANAGED BY PC2 32 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION - The transmission line should avoid areas with high trees such as industrial trees, planted and natural forests so as not to impact the eco-system. - The transmission line should not traverse or be closed to important projects such as airports, mine warehouses, radio stations. - The transmission line should avoid slope sides to reduce landslide and erosion. - The transmission line should avoid turnings as much as possible due to high cost of angle towers. - The transmission line should use same ROW with existing 110-220 kV transmission lines in order to facilitate management and operation works. Details analysis for alternatives for each sub-project are described in the following: Alternatives and comparative analysis: I. Dai Ngai & Soc Trang - Dai Ngai transmission line. Dai Ngai sub. is located next to Highway No.60, on the paddy field of Ngai Hoi 2 hamlet, Dai Ngai commune, Long Phu district, Soc Trang province . For the transmission line there were two alternatives considered. Detailed line route is shown in the Map. Alternative 1: Starting from the existing Soc Trang Substation, the TL 110KV traverses through paddy fields, canals, and goes on the left side of Highway No.60 in Soc Trang province and connects to the busbar of Dai Ngai Substation. Total lengh of the line is 20,286 m. Alternative 2: Starting from the point on existing 110kV Tra Noc- Soc Trang T/L (at tower no. 390), the line traverses through paddy fields, canals, and goes on the left side of Highway No.60 in the same route of Alt. 1 and connects to the busbar of Dai Ngai Substation. Total lengh of the line is 17,122 m. Comparison is shown in the following table: Issues Alternative I (selected Alternative 2 option) Length (km) 20.286 17.122 + Topography paddy fields, fruit tree paddy fields, fruit trees land areas The alternative 2 is about 3 km shorter than the alternative 1. Two alternatives have similar environment along the ROW, so the impacts on environment of Alternative 2 is some what higher. However, on safety of power supply, Alternative I will provide much higher reliable electricity supply to Dai Ngai Substation, compared to EIA OF PROJECTS MANAGED BY PC2 33 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION Alternative 1. In this case, the decisive factor for line route selection is the technical aspect. Alternative 1 is therefore selected and agreed upon with Soc Trang Provincial People's Commitees. 2. Tan Uyen Sub. & Binh Chuan - Tan Uven TL Tan Uyen Sub. is located on the lelf of No.747 road, 2km far from Tan Uyen town, on the territory of Tan Uyen district, Binh Duong province. Two altematives were considered for the substation site and the associated transmission lines: Alt.l: The TL 110kV departs from the existing Binh Chuan substation, going in left side along the 747b interprovincial highway, traversing Thuan An and Tan Uyen district, Binh Duong province before connecting to Tan Uyen Substation. Alt.2. The TL also departs from Binh Chuan Substation but going in the right side of 747 b interprovincial highway before connecting to Tan Uyen Substation. Comparison is provided in the following table Issues Alternative 1(selected) Alternative 2 Length of TL branch 14,664 m 13,358m ROW 219,960 in2 of rice field 200,370 m2 of rice fields and fruit trees Affected house 13 28 Alternative 2 is about 1.3 km shorter than alternative 2 with less areas affected by the line ROW. However, there are more trees to be cut under Alternative 2 as its ROW traverse larger amount of perennial crops land. Alternative 2 also has less houses affected by the line. Therefore this alternative is selected and agreed upon by the Provincial People Committee of Binh Duong. 3. Ngai Giao Sub. & Ba Ria - Ngai Giao TL: Ngai Giao sub. is located next to My Xuan - Hoa Binh road, on the cashew land of Tan Giao hamlet, Ngai Giao town, Ba Ria Vung Tau province. There are two altemative routes for the 1 10 kV transmission line considered. Alt. I: The TL 110KV departs from 110 kV Ba Ria substation, traversing through paddy field, hill, rough land on the territory of Ba Ria town and Chau Duc district, Ba Ria Vung Tau province (on the left side of Road 736) before connecting to Ngai Giao Substation. Alt. 2: The TL 110KV departs from the location G. 17 of the 110kV Ba Ria - Xuyen Moc T/L (which will be coming soon), traversing through paddy field, hill, rough land EIA OF PROJECTS MANAGED BY PC2 34 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION on the territory of Long Dat and $Chau Duc district, Ba Ria Vung Tau province (on the left righ side of Road -736) before connecting to Ngai Giao Substation. Comparison is shown in the following table Items Alternative 1 (chosen) Alternative 2 + Length (km) 18.335 24.860 ROW 275,325 m2 372,900 M2 + Topography paddy fields, fruit trees paddy fields, fruit trees + No. of affected house 21 32 Alternative 2 is 6.5 km longer than Alternative I and larger land affected by line ROW. Alternative 2 also affects more houses. Therefore, Alternative 1 is selected and has been agreed upon by Ba Ria Vung Tau Provincial People's Committee. 4. Hong Ngu Sub. & An Long - Hong Ngu TL Hong Ngu Sub. is located on the paddy field of An Thanh B hamlet, An Binh A commune, Hong Ngu district, Dong Thap province. Due to simple topography, there only one alternative routes for the 110 kV transmission line considered. The TL 110KV departs from the existing An Long substation, going along Highway No.30 on the area of Tam Nong district, Hong Ngu district, Dong Thap province before connecting to Hong Ngu substation. This is the shortest route from An Long Substation to Hong Ngu district. The line route has been agreed upon by Dong Thap Provincial People's Committee. 5. Thoi Binh Sub. & Ca Mau - Thoi Binh TL There is only one option for the substation site and the transmission line as the topography is simple. Thoi Binh Sub. is located next to Tac Thu road - Thoi Binh town, on the plain of Thoi Binh commune, Thoi Binh district, Ca Mau province. The TL 110KV traverse paddy fields and shrimp farming fields in Ca Mau town and Thoi Binh district, Ca Mau province and is the shortest route from Ca Mau 2 substation (Ca Mau city) to Thoi Binh district. The line route has been agreed upon by Ca Mau Provincial People's Committee. EIA OF PROJECTS MANAGED BY PC2 35 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION CHAPTER VIII DISPOSAL OF POLYCHLORINATED BIPHENYLS (PCB's) The project is to construct 15 new substations and transmission lines and will not rehabilitate the existing facilities. The project will procure and install new and modem equipment without PCB. Equipment manufactured before 1954 or equipment using PCB substance such as transformer and capacitor will not be used. A specific plan for disposal or management of PCBs therefore shall not be required in the report. EIA OF PROJECTS MANAGED BY PC2 36 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION CHAPTER IX PUBLIC PARTICIPATION AND DISCLOSURE World Bank (the Bank) policy regarding community involvement provided in detail in the WB Public disclosure Policy BP 17.50. It is summarized as follows: It is required that the boffower 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 conmmunity 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 determined by the fundamental principle "of people, from people andfor 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 175/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 EIA 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 EIA OF PROJECTS MANAGED BY PC2 37 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION 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 ensure that issues raised in affected communities are comnmunicated to the other participants in the EA process, including various public agencies and NGOs that may be in the larger process pf 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. - Consultants will inform the participants of the major technical and environmental issued of the project and mitigation measures. - In the meetings all questions of PAP should be addressed, all recommendations and concerns of PAP and PC should be recorded. Materials to be presented in the meetings. The Consultants will present the following materials: - Booklet/summary of F/S Report and EIA Report - Maps of the project site 1. Aims of public consultation and information dissemination Information dissemnination 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. EIA OF PROJECTS MANAGED BY PC2 38 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION - Collect information on project environment, local people's concern on project in general and on-environmental aspects in particular. - Find coordination and participation of local people in realizing impact risks as well as supervising the project activities. - Reduce probability for social conflicts. - Reduce risk for project delay. - Help to establish a comprehensive environment management plan and thus, maximize the project socio-economic benefit. Public consultation and information dissemination were scheduled for 2 stages: project preparation and project implementation. 2. Public consultation and information dissemination during project preparation stage: During project preparation stage, the following activities were carried out sequentially: Phase I-Activity 1: Information & discussion with local authorities on the line route. After studying maps and visiting the site, consultants 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 5±.6/2001. 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 forns were delivered to affected households. This activity was carried out in 5-6/2001. Phase I - Activity 3: Meetings with PAPs When the survey finished, consultants in coordination with the commune officials held meetings with PAPs having land in the line ROW and with village representatives. In these meetings, consultants officials informed 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. The activities were carried out in June, 2001. EIA DF PROJECTS MANAGED BY PC2 39 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION Phase I - Activity 4: Consullalion on EIA Basing on the survey result, consultants prepared draft EIA and sent to EVN, WB and concerned PPCs for comments. All comments received were taken into consideration, incorporated in the next version for approval by relevant authorities. In December, 2001 to January 2002, meetings with PAPs, NGOs and local authorities in the project sites were carried out to get feedback and comments on the draft EIA. 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 EIA. The activity was carried out in December-January, 2002. Records of the public disclosure meetings provided in Annex 3. Phase I - Activity 5: Approval of E1A Based on comments received, the consultant revised ElAs. The revised EIA were sent to WB, to the concerned provincial committee to DOSTE for approval and the environmental certificates. This shall be legal basis for EIA implementation. Also, the draft EIA report has been made available at DOSTEs and PPCs from January 2002 for public display. Schedule of public consultations for each sub-project were provided in following Table 9.1 EIA OF PROJECTS MANAGED BY PC2 40 UPlRADING'110KV SYSTEM FOR RURAL ELECTRIFICATION Table 9.1: DATE ON PUBLIC PARTICIPATION AND DISCLOSURE Sub-project Items Luong Chon Phu Giong Ca mau Hong Ngai Thoi Hong Dai Ninh Bu Dang Long Binh Tan son thanh giao rieng 2 dan Giao binh ngu ngai Hai Dat Minh Uyen Inforrnation & May/O I May/0l May/01 May/O I May/O I May/O 0 June/0 I May/01 May/O 0 May/0 I May/01 May/O I May/O l May/O I May/01 discussion with local authorities, on the line route.

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 environment and people at the stage would be worst. The following information 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 informn them of the project policy. * Information on EIA: Another information campaign on enviromnent 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 information such as: project implementation schedule, project components, infornation on project impacts on local people and mitigation measures.. 2. Environment information booklet An environment information booklet (EIB) on impact and mitigation measures will be prepared basing on the approved EIA 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: - Project basic description - Description of the main project components to be constructed in the area - Project design objectives - Implementation schedule - Project impacts - Mitigation measures - Institutions Responsible for EMP EIA OF PROJECTS MANAGED BY PC2 42 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION - Monitoring - Description of the detailed impact of the project on the specific household 3. Notificationfor local authorities on environment impacts: All environment impacts induced during construction as well as operation of the project, if any, will be announced in meetings with local authorities so as to find prompt solution in order to avoid conflicts and implementation delays. All problems will be solved in monthly meetings between local authorities, PNPMB, contractors and consultants. EIA OF PROJECTS MANAGED BY PC2 43 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION CHAPTER X ENVIRONMENTAL MANAGEMENT PLAN (EMP) The Environmental Management Plan consists of regulations, measures of supervision and mitigation carried out during the project implementation in order to eliminate, overcome and mitigate the environmental and social impacts to the acceptable level. The plan also includes the necessary measures for organization and finance to be able to carry out this project. 1. MITIGATION OF ENVIRONMENTAL IMPACTS Generally, for the areas where construction of lines and substations, we have some the following conclusions: - For topography, the lines and substations locations going through areas with a little difference of altitude, mainly going along the main roads, convenient for materials transportation, construction and execution. - The construction will cause some environmental impacts for areas where the lines going through, the most remarkable impact will be to the populated areas with dwellings in the line's corridor, but only in the forms of rearrangement or movement in the existing land lot with small scale, unnecessary to make up a resettlement plan. During construction period, the impact of noise, dust shall be minimize by some of mitigation measure such as: performing all work during daylight, watering construction site and covering truck load. - The sub-projects almost do not influence negatively to the natural environment and surrounding landscape. The substation are located in exposed area, in its fence, below the transformer location, it is arranged a concrete oil pit, big enough to absorb complete content of transformer oil in the case of spillage. The transformer shall be isolated and cooled by oil without PCB's. - In the electric projects, the factors on fire, explosion prevention and fighting and electrical safety always highly concerned, measures for limit have been brought in the Process and Normn of Electricity Sector during the design and construction periods as well as in the management & operation period. EIA OF PROJECTS MANAGED BY PC2 44 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION - After finishing construction, during the operation period, the project almost does not issue emissions, not to cause noises and to be safe for the inhabitants in the areas. However, the remaining impacts to the environment still exist a little but almost not worth to mention. Summarily, the enviromnental impact problems for the project is basically that the imnpact by compensation and rehabilitation houses located in the line's ROW. This problem has been mentioned in detail in RAP document.

INSTITUTIONAL STRENGTHENING 2.1. Equipment purchases There will be no equipment purchase because Monitoring Contractor will perform such activities. Monitoring Contractor will be selected after procurement process during which Contractor should provide evidence on possession of necessary equipment and previous experience in such works. 2.2. Training/Study tours Training courses should be held with following environmental related activities: During Construction /Operation, maintenance, reparation phase: 1. Environmental monitoring & management during construction/operation 2. Mitigation measures on environmental impacts 3. Safety methods Training of the two phases will be carried out in one short course of about 01 week as it aims on general environmental issues: pollution of water, air, lands; protection and mitigation measures on environmental impacts. However, the project covers 11 provinces with different project sites, training course may be organized 3 or 4 times in the 11 provinces. The course would be realized for staff that will be responsible for environmental management. Participants should be from constructors' teams, Provinces' power services, PC2 and PMB. The objectives of the training is to train staff so that they could successfully provide law enforcement in the field of environmental protection, especially pollution may caused during construction/operation phase Approach to the formal training program will be to provide an educational experience that will help the trainees to better accomplish their on-the-job responsibilities. The emphasis of the program should be pragmatic and practical. Strong emphasis should given to on-the-job training which would include an explanation of what is to be done and the trainees will be expected to put these procedures in practice under the supervision of the training personnel. All training activities could be carried out under guidance of experts from Ministry of Science-Technology and Environment (MOSTE), DOSTE, the World Bank or other professional institutions. EIA OF PROJECTS MANAGED BY PC2 50 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION Study tours should be the back up activity for training. They could be recognized as study visit to substations and network sites. Through those study tours participants would become acquainted with environmental management, policies, procedures and practices utilized in those Environmental Agencies and with monitoring activities that are conducted in order to provide necessary information for environmental management. Participants of the study tours would be the same ones as those that would participants as trainees. 2.3. Cost estimate for implementation: I Cost for training management and operation staff: 5,000,000 VND/person x 28 persons (2 persons for each unit: 1 1 provincial power services, PC2; 4 140,000,000 VND persons from consulting companies) 2 Cost for supervision and monitoring environment protection measures during construction phase: 3,000,000 VND/sub-project x 15 sub-projects 45,000,000 VND 3 Annual Cost for supervision and monitoring environment protection measures : 1,000,000 VND/y x 25 years x 15 sub-projects 375,000,000 VND 4 Contingency: 10% (1+2+3) 56,000,000 VND. Total 616,000,000 VND. Total (by USD, Ex.rate: USD1=15000VND) USD 41,067 During the construction phase, this cost will be regarded into the total investment cost of project. Until the operation phase, it will be added up the operation cost. The capital cost for implementation brought out from the corresponding capital cost by Electricity of Viet Nam. 3. SCHEDULE During design phase of the Project, mitigation measures will be applied parallel to technical design for construction. It is expected to start from 2/2002 to 5/2002. Mitigation and monitoring activities during construction phase will be carried out a long with construction phase. It is planed to start in 3/2003 and finished in 8/2003. EIA OF PROJECTS MANAGED BY PC2 51 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION Mitigation and monitoring activities during operation will run together with maintenance activities. These activities will be planned and started after the project completion. Training activities and study tours are planned according to item 4. would be started before construction phase (around 1-2/ 2003). 4. INSTITUTIONAL ARRANGEMENTS 4.1. Institutions' responsibilities The institutions and offices that have been responsible for the preparation of this EIA or will be in charge of its implementation are: - Electricity of Vietnam (EVN) - Power Company No. 2 (PC2) - Project Management Board (PMB) - Provincial People's Committee (PPC) - District People Committee (DPC) - Commune People Committee (CPC) - Construction Contractor Besides, the project will be implemented under guidance of the Ministry of Science-Technology and Environment (MOSTE), Department of Science, Technology and Environment (DOSTE) in the field of environmental management. The responsibilities and roles of the above institutions is specified as following: * Ministry of Science-Technology and Environment (MOSTE) Establishing in 1991, the MOSTE's mandate is to set policies and guidelines for environmental management, develop standards, coordinate research, provide technical back up and support to the line ministries, and provide support and training to provinces. MOSTE is divided into number of divisions dealing with planning, EIA, pollution control, waste management, environ-mental monitoring, inspection, information and training. * Department of Science, Technology and Environment (DOSTE) Recently the DOSTE as the provincial level have been instructed to add environmental protection to their mandate. However most of provincial institutions are suffering the lack of capacity to conduct EIAs and environmental monitoring of more complex projects and have to rely on the national institutions. The provincial DOSTEs are funded from provincial budgets and report directly to the People 's Committees. EIA OF PROJECTS MANAGED BY PC2 52 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION * Electricity of Vietnam (EVN) Electricity of Vietnam is an Employer of the project and is responsible for evaluation of F/S, technical design for construction, approval of bidding plan, bidding documents... In addition, within EVN there's a department of informatics, technology and environment will be in charge of all matters related to EIA of the project. * Power Company No. 2 (PC2) Power Company No.2 is the owner of the project and responsible for the whole project including environmental management program. PC2 will supervise the establishment of specialized bodies in charge of the preparation and implementation of the project and will have to approve all decisions taken by PMB * Project Management Board (PMB) The PMB is established by PC2 to coordinate all project activities including environmental management such as mnitigation measures, monitoring. The PMB is also in charge of: - Overall planning, management and monitoring of the environmental management - Ensuring that all environmental protection and mitigation measures of environmental impacts are carried out in accordance with policies, regulations on environment and other relevant laws. - Coordinating with provinces' people committees, provinces' power services, districts' people committees... in environmental management activities. - Being in charge of organizing training courses of local staff (provinces, districts) and contractors' teams on mitigation measures and safety methods (inviting professional expert on environment shall be included). - Carrying out internal monitoring and independent monitoring (may be contracted with Power services or consulting units) of the project. - Supervising and providing budget for monitoring activities. - Reporting on the environmental information to PC2 and the WB * Provincial Power Services (PPS) - Assist PMB in supervising environmental inpact mitigation and protection during operation. Implement environment mitigation plan during operation. Submit reports on environment status to concerned DOSTE and PC2.

Reporting system A proposal on environmental protection and impact mitigation measures to be applied will be prepared by the contractor and sent to PMB 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. EIA OF PROJECTS MANAGED BY PC2 54 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION Construction Contractor will provide monthly reports to the PMB 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 PMB, 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 PMB 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, PMB will prepare quarterly Environment Monitoring Reports for submission to the PC2 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 PC2 in which summarizes the environmental protection measures implemented, problems encountered, actions taken to resolve environmental problems and results of environmental monitoring. PMB under instruction of PC2 will have the authority to spend, shutdown change operations according to recommendation of the DOSTEs. 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 according to technical specifications and contract requirements related to the environment. This will be proved by Monitoring Contractor reports to DOSTEs. PMB are authorized to supervise and check all expenditures referring to mitigation and monitoring activities through recomrnendation 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 PC2, PMB about suspension and order to proceed according to their directive. 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 EIA OF PROJECTS MANAGED BY PC2 55 UPGRADING 110KV SYSTEM FOR RURAL ELECTRIFICATION 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.
