PROJECT DESCRIPTION AND SCOPE OF WORK GENERAL DESCRIPTION This is a subproject under the Trung Son hydropower project financed by the World Bank. Reasons of Subproject proposals: Trung Son hydropower plant will be constructed on the Ma River, in the territory of Trung Son commune, Quan Hoa district, Thanh Hoa province. Installed capacity of the hydropower project is 260 MW, annual electricity produced will be 1056 GWh. Trung Son hydropower project will bring benefit in term of power generation and flood control. Construction of the subproject “Mai Chau 110 kV substation and 35 kV power line supply for construction of Trung Son hydropower project� is aimed to meet the local power demand, supply electricity for construction of Trung Son hydropower project and supply electricity for ressettlement sites. The subproject is consisted of two components: - Mai Chau 110 kV substation and connections; - 35kV power line supply for construction of Trung Son hydropower project (19. 427 km). The construction of Mai Chau 110 kV substation and 19.427 km of 35 kV power line can cause negative impacts on the environment and local communities during pre- construction phase, construction phase and operation phase. In order to ensure that potential negative impacts are identified and mitigated during subproject implementation and that the subproject complies with the Environmental Assessment policy (OP/BP 4.01) of the WB, an Environmental Management Plan (EMP) of the subproject has been prepared in compliance with the Environmental Guideline (EG) prepared under Trung Son hydropower project. This EMP is prepared with reference to Environmental Management Framework (EMF) of the Distribution Efficiency Project sponsored by the WB. Application of some items of EMF is suitable in this case due to similarities of the Subproject and other subproject under DEP. This EMP includes: the subproject description, legal and policy frameworks, applicable environmental technical standards and regulations, potential negative impacts, proposed mitigation measures to be implemented prior and during construction and operation, and implementation arrangements. The EMP also includes Environmental Codes of Practice (ECOP) that will be integrated into bidding and contractual documents, monitoring and supervision during the implementation. Environmental Management Plan (EMP) 4 Subproject: Mai Chau 110 kV substation and 35 kV power line supply for construction of Trung Son hydropower project EIA of Trung Son hydropower project (including the subproject Mai Chau 110 kV substation and 35 kV power line supply for Trung Son HP) was approved by Ministry of Environment and Natural resource by Decision N0 1257/QD-BTNMT dated 17/6/2008 on approval of EIA for Trung Son hydropower project. PROJECT DESCRIPTION 1.1. Construction of Mai Chau 110 kV Substation and its 68 m Connection Line 1.1.1. Alternatives for subproject location. General requirements on Subproject’s locations Selection of location for Mai Chau 110 kV substation is made based on the following technical and financial requirements: - To comply with Master plan for power development No 6 and comply with Local socio-economic plannings; - Technical requirement: To ensure to have enough area for the substation and power line connections. The location should be optimized in term of having minimum power loss for power grid; - Natural condition requirement: Geological pattern is suitable for substation construction, climate is suitable. Topography is preferably to be flat, open to enable access and connections with the power grid. - Location should be convineinent for construction, transportation of substation’s equipment during operation phase. - Minimize compensation and ressettlement, avoid impact in cultural and historical valuable sites. Minimize impact on local landscape and views. - Minimize loads on ground leveling. - Make use of the existing facilities such as road, power source, water source. - Minimize environmental impacts caused by the substation to surrounding areas. Substation location alternatives Based on the above-mentioned requirement, technical consultants (PECC4) have investigated and proposed 3 alternatives described bellow: - Option 1: Mai Chau 110 kV substation will be constructed on rice and dry crop field of Na Quan (Tong and Dau villages), Tong Dau commune, Mai Chau district, Hoa Binh province. - Option 2: Mai Chau 110 kV substation will be constructed on agricultural alnd of Vang village, Mai Chau township, Mai Chau district, Hoa Binh province. - Option 3: Mai Chau 110 kV substation will be constructed on the agricultural land next to the existing Mai Chau 35 kV substation in Mai Chau township, Mai Chau district, Hoa Binh province. Environmental Management Plan (EMP) 5 Subproject: Mai Chau 110 kV substation and 35 kV power line supply for construction of Trung Son hydropower project Among these three options, the option 3 having connecting 110 kV power line overpassing deeply in center of Mai Chau township. This affect affect development of Mai Chau township so there will be many disadvantages to local development planning. Beside that, the option 3 will not comply with Decision 5638/QDD-BCT dated 22/20/2008 of MOIT on “Decision on amandement of Power Development Planning for Hoa Binh Province in period 2006- 2010 with vision to 2015�.

Beside this road there will not be any access road need to create for ROW maintenance Environmental Management Plan (EMP) 24 Subproject: Mai Chau 110 kV substation and 35 kV power line supply for construction of Trung Son hydropower project Conclusion: Since implementation of the subproject would mainly cause land acquisition, increased dust generation, air pollution, and domestic waste production during the construction phase. However, these impacts are not significant, temporary, and localized, and can be mitigated available mitigation measures. During the operational phase the main impacts would be visual, due to the alteration of the previously existing landscape, and potentially on the avifauna, who is at risk of collision and electrocution. However, as the TL follows exiting infrastructure and the height of pylons and wires is moderate; these impacts are anticipated to be low. Therefore, the subproject is assessed as B environmental category according to the World Bank’s operational policy OP4.01 on environmental assessment, requiring an ESIA and an EMP as analytical and mitigation instruments. Environmental Management Plan (EMP) 25 Subproject: Mai Chau 110 kV substation and 35 kV power line supply for construction of Trung Son hydropower project 3.2. Potential Impacts Table 3.2. Potential impact No Impact Magnitude Duration Description of the impacts Evaluation of impacts Pre-construction phase 1 Permanent and temporary Medium Short Total permanent land acquisition of the Subproject is as follows: Medium and mitigable land acquisition Long - Mai Chau substation: 8,336.0 m2; - The land acquired for pole foundations of the power line is 169.0 m2. - Area of land within ROWs is 115,482 m2. This land is not acquired but trees higher than 4 m can not planted. Total temporary land acquisition is 27,728 m2, of which rice field land is 163.083 m2; land for dry crops is 4,806 m2. 2 Impact on Subproject Medium Long term - Total number of HHs affected by the Subproject is 306 HHs; Medium affected household - Affected types: land loss for foundation, substation; having house within ROWs; loss of trees and crops, rice; trees will be damaged during cable pulling. 3 Loss of vegetation due to Medium Long - In Hoa Binh province, the substation and power line are located and Medium land clearance for the overpassed mainly rice fields. In Thanh Hoa province, the power line substation will overpass area planted by bamboo Luong forest. Number of Luong trees will need to be cut is 2.504. Some other trees will also need to be cut for land acquisition, they are: 24 fruit trees, 25 eucalyptus trees, etc. 4 Health risk due to None None - The Subproject would not use chemicals or explosives; None Environmental Management Plan (EMP) 26 Subproject: Mai Chau 110 kV substation and 35 kV power line supply for construction of Trung Son hydropower project No Impact Magnitude Duration Description of the impacts Evaluation of impacts explosives, chemical - Subproject sites were cleared for landmine after war time and used for hazard agriculture for a long time. 5 Impact on historical and None None - There are no historical and cultural resources near and inside the None cultural properties Subproject area Construction phase 6 Impact in Tong Dau Medium Short - Tong Dau primary school is about 150 m far from the proposed Medium and Mitigable primary school substation. Therefore, the school might be affected by noise, dust, vibration during construction time. However, these impacts will last only in a short period of time (about 3 months, when ground leveling and civil work are occurred). These impacts can be mitigated by application of mitigation measures as specified in Chapter 4. - An access road to the substation is created by widening an inter commune road of Tong Dau commune. This inter commune road is also passing Tong Dau primary school. So transportation of pupils and teachers might be affected during construction time. This impact will mostly occur during ground leveling, road construction, civil work for substation construction. When the access road is completed, subproject’s vehicles will use only the new road. So impact on local traffic will not be considerably affected. 7 Surface water Medium Short - Ground leveling, construction of foundation, substation and Medium and contamination. substation’s access road might washout soil, rock to the surface water Mitigable system of region; Environmental Management Plan (EMP) 27 Subproject: Mai Chau 110 kV substation and 35 kV power line supply for construction of Trung Son hydropower project No Impact Magnitude Duration Description of the impacts Evaluation of impacts - Mai Chau 110 kV substation is about 50 m far from a small stream. This stream is going along national road No15. This is the only one surface water source near the substation. - The 35 kV power line will 2 times overpass Xia stream and one time overpass other small stream in Chieng Chau commune. Width of these steams at the over passing point is from 4-7 m. Beside these, the power line will not overpass other surface water such as river, stream, and reservoir. - Construction of foundations near the streams might cause risk on water contamination due to debris, construction materials washed out to the water bodies. - The Subproject area is quite flat; therefore, the risks of erosion, soil and construction materials runoff are not high. - Excavation is planned to do in dry season. Excess soil will be reused to fill in the poles’ foundations. Thus there will be no soil, rock left after the Subproject implementation. - No tower will be constructed in the above mentioned streams. - Thus the impact on surface water pollution in the Subproject area is medium and can be mitigated. 8 Noise and vibration Medium Short - Noise and vibration are caused by: equipment, material transportation, Medium and Subproject's vehicles, pole's erection and cable's pulling, generators (if mitigable there are any); Environmental Management Plan (EMP) 28 Subproject: Mai Chau 110 kV substation and 35 kV power line supply for construction of Trung Son hydropower project No Impact Magnitude Duration Description of the impacts Evaluation of impacts - About 100 m far from the substation is Tong Dau primary school. Few houses are about 200 m far from the substation location. These are the nearest areas with human living in the substation location. The nearest residential area of the substation is center of Chieng Chau commune (2 km far from the substation). - The 35 kV power line will mainly overpass rice fields, bamboo Luong forest. Sections of the power line going near residential area is G3-G4 (Mai Chau township), G21-G22 (Van Mai commune). These residential areas are about 70 m far from the power line. Main part of the power line are far from residential areas so construction activities of the subproject will not impact to normal life of local people. - Construction materials will be supplied by local supplier within medium distance to construction sites. - Equipment, cables, materials transported from Ha Noi and from Mai Chau district to the sites through national road 15 and provincial roads system. After that these materials will be transported manually or half- manually to construction sites. - Due to the above reasons, the noise and vibration impact caused by the Subproject is considered as medium, happening in a short period of time and can be mitigated. 9 Soil erosion Small Short - The topography of the substation area and the power line is quite flat. Mitigable Vegetation cover is quite good. From G26 to the end point (about 4,031 Environmental Management Plan (EMP) 29 Subproject: Mai Chau 110 kV substation and 35 kV power line supply for construction of Trung Son hydropower project No Impact Magnitude Duration Description of the impacts Evaluation of impacts m), the power line will overpass hills with high slopes. However, in this area is bamboo Luong forest. Luong trees are very well grown. Vegetation cover is quite thick so risk of soil erosion is low. - Excavation, backfill and ground leveling are prioritized to be done in dry season; - Regarding soil erosion, the impact is assessed as small according to small scale of the sub-station site, short construction time. Furthermore, these impacts can be reduced to even smaller when implementing mitigation measures. 10 Air pollution Medium Short -Dust generated from soil excavation, ground leveling especially during Medium and dry seasons. The subjects to be affected by dust are people living, Mitigable working near roads used for transportation of the constriction materials such as national, provincial, district, inter commune roads. - The Subproject site is away from residential and urban areas therefore air pollution (dust) would not affect much on people living in the Subproject area; The most affected area by air pollution will be substation location, center of Chieng Chau commune, center of Van Mai commune. These areas will be sprayed by water during dry and strong wind times. - There are 3 residential areas about 70 m far from the Subproject sites. Construction activities at these sites are just construction of foundations. Size of the foundations is 2 m x 2.3 m x 2 m (depth) so impact can be assessed as medium and can be mitigated as described in Table 4.1. Environmental Management Plan (EMP) 30 Subproject: Mai Chau 110 kV substation and 35 kV power line supply for construction of Trung Son hydropower project No Impact Magnitude Duration Description of the impacts Evaluation of impacts Other residential areas are far from the subproject sites. 11 Ecological impact Small Short - Proposed substation is located in very intensively used by human Small and activities. mitigable - The main land use pattern in the substation area and ROWs are rice fields and dry crops. There are 2.504 km from 19.427 km of the power line overpassing bamboo Luong forest. This forest is planted and periodically exploited for commercial purpose. - Except rice field, Luong forest, there are few other trees, fruit trees, eucalyptus are impacted. These trees mainly have economic but not ecological value. - There is also no special impact caused by Subproject on fauna since the Subproject sites are mainly rice fields, planted Luong forests, gardens, land along roads. These are very common patterns in the area. Beside these, there is no special habitat observed. 12 Traffic disturbance Small Short - Transportation of materials and equipment will disturb the normal Medium and including water-way traffic in the areas during short period of time. Mitigable transportation - The substation is located in an open area; the transportation of construction materials is generally easy due to relatively developed traffic system in the subproject area. - The power line will 4 times overpassing roads having width from 5- 10 m; 21 times overpassing roads having width less than 5 m. When pulling wires across these roads, scaffolds will be constructed to enable Environmental Management Plan (EMP) 31 Subproject: Mai Chau 110 kV substation and 35 kV power line supply for construction of Trung Son hydropower project No Impact Magnitude Duration Description of the impacts Evaluation of impacts normal transportation on this road. These roads are quite small with low density of transportation so traffic in these areas will not be seriously affected. 13 Degradation of the Medium Short - Transportation of construction materials with high frequency may Medium and existing rural roads, cause damage to the inter-commune roads; Mitigable rice fields and path at - Currently local authorities and people supervise the management of edges of rice fields. rural road quite well. Large load transportations are not allowed to run through roads whose quality is not good enough. This is also an issue that the contractors have to comply and thoroughly calculate transporting options to avoid rural road degradation. - Manually or half-manually transportation material to construction sites might also cause damages to the rice fields, path at edges of the rice fields. - The road section that most potentially be damaged by subproject activities is the inter commune road that will be widened for an access road of the Mai Chau substation. Other roads used by subproject’s vehicles are potentially less affected. 14 Solid waste generated Minor Short Excessive soil and materials will be used for poles’ foundations filling. Minor from soil excavation The volume of excessive soil is often not enough for foundations, sometimes it has to purchase and transport from other places. Therefore it could be said that impact is in minor level. 15 Environmental Medium Short - The subproject implementation is expected to be completed in 9 Medium and Environmental Management Plan (EMP) 32 Subproject: Mai Chau 110 kV substation and 35 kV power line supply for construction of Trung Son hydropower project No Impact Magnitude Duration Description of the impacts Evaluation of impacts impacts caused by months, from that construction period will last for 5-6 months. High mitigable construction workers construction time is last from 5 to 6 months. The remaining time is mainly reserved for the installation of equipments; - It is expected to be 72 workers involving with construction of the substation. These worker will create their camps in substation's area, where is reserved for the second phase (installation of another transformer). Number of workers involving with construction of the power line is about 80; they will be divided into two groups and will stay in houses rent from local people. Workers will be chosen from the skilled ones in the region so in this camp number of worker will be also about 30-40 workers/each site. - In the camp for substation, other ancillary’s constructions such as bathrooms, toilets will be built for workers to use. - Camp sites will dispose domestic solid wastes that can cause environmental pollution. However these wastes are mainly package materials, leftover food... with small amount. 16 Conflict between Small Short - Conflict might cause because of: Difference in incomes, cultures, Minor construction worker behaviors; However worker are come from the region so these and local people differences are not considerable. - The subproject will be implemented in well developed area with high population density; the number of workers is not considerable in comparison with local people. Environmental Management Plan (EMP) 33 Subproject: Mai Chau 110 kV substation and 35 kV power line supply for construction of Trung Son hydropower project No Impact Magnitude Duration Description of the impacts Evaluation of impacts - Stay duration of workers in each site is short (6-9 months), so the impact therefore considered as minor. 17 Health and safety Medium Short - Accidents might happen during construction if the safety issues are not Medium and well considered. mitigable - Accidents might happen to the workers or local people living around the subproject area. 18 Flooding of an area Small Long - An area used for substation is land used for rice field. This area will be Small surrounding the leveled to 0.3 m higher than the existing level. substation - By leveling up the ground for the substation, rice field in surrounding area might be flooded; - Water level in rice field is controllable by farmers with support of irrigation system. In case water is increased, farmer will regulate water level accordingly. Flooding will not occur. - Experiences from other similar projects show that this impact was not happened. However subproject owner will work with farmers during construction phase and operation phase to check the problem. In case flooding would occur, Project owner will design proper drainage system to keep water regime as closed as the existing conditions. The impact is assessed as small and can be mitigated. 19 Interruption of utility Small Short - Installation of power line requires power interruption to some areas. Small services -Due to power interruption some services which' operation depend on Environmental Management Plan (EMP) 34 Subproject: Mai Chau 110 kV substation and 35 kV power line supply for construction of Trung Son hydropower project No Impact Magnitude Duration Description of the impacts Evaluation of impacts power supply would be interrupted. Operation phase 20 Supplying electricity Large Long - Subproject is primary aimed to supply for construction of Trung Son Positive for construction of HPP. In later phase, the power line and substation will supply electricity Trung Son HPP for resettlement sites of trung Son HPP. - The subproject actively supports for development of the area; handcraft and traditional work and services can be developed. - Increase the quality of life for local residents due to sufficiency and stability of power supply. 21 Impact on Tong Dau None None - During operation phase, the substation will not cause noise, dust, No impact primary school. vibration ... so Mai Chau substation will not cause impact on activities of the school. - The substation protected by walls, guards so pupils can not access, therefore accidents related to electricity could not occurred to pupils as well as to local people. 22 Health and safety Minor Long - There are no habitants in the substation area. The number of Minor and employments in the substation is small (about 10-15 people divided into mitigable shifts). The safety regulations in the substation are guaranteed so there will be no impact on health and safety of workers; - If safety regulations are not complied, it might affect on heath workers, however this case is extremely rare. Environmental Management Plan (EMP) 35 Subproject: Mai Chau 110 kV substation and 35 kV power line supply for construction of Trung Son hydropower project No Impact Magnitude Duration Description of the impacts Evaluation of impacts - According to Vietnam Government regulations, houses are allowed to be existed in the ROW of 110 kV and 220 kV power line. However these houses are required to meet certain requirements as described in Table 4.1 of the EMP. - 35 kV power line will not cause impact to people living within and near ROW. 23 Electromagnetic field None None - The power line is designed according to existing technical regulations; None electromagnetic field will not exceed permissible value (5kV/m). 5 kV/m is safe electromagnetic field level for human health. - When the power line is designed according to technical standards, the electromagnetic field in the ROW is always lower than 5 kV/m for power line with voltage under 220 kV. - At this electromagnetic field level, there will not be effect of electromagnetic field on human health. 24 Oil, hazardous waste Minor Long - No PCBs containing oil will be used during the subproject’s Minor and contamination construction and operation; mitigable - During the subproject operation, some chemical will be used such as accumulators, batteries, dielectric oil, lubricants etc. These equipment and chemicals will be registered and managed as regulated by Circular 12/2011/TT-BTNMT dated 14/4/2011 on Management of hazardous wastes. These practices are applied for all other substations of EVN and will apply for Mai Chau substation as well.
