INTRODUCTION The subproject Bac Ninh 3 220kV substation and connection line is one of the subproject identified for the second phase implementation under the World Bank financed Transmission Efficiency Project (TEP). The subproject will be implemented in Yen Phong district of Bac Ninh province and Soc Son district of Ha Noi City. The implementation of the subproject is in line with the national Power Development Master Plan 7 (PDMP7). This implementation is to receive and transmit capacity of 220kV voltage from national power system, to distribute capacity to 110/22kV substation in region and to meet load demands, strengthen reliability and supply energy for industrial zones of Yen Phong 1, Yen Phong 2, urban and residential zones, in Yen Phong district, other regions in Bac Ninh province and surrounding regions. Activities of the subproject are to (i) construct a 220/110/22kV substation with capacity of three transformer units of 220/110kV-250MVA and two transformer units of 110/22kV 63MVA; (ii) construct a double-circuit 220kV connection line with 4,723m in length from connection tower of Hiep Hoa Dong Anh Bac Ninh 2 500/220kV transmission line to 220kV switchyard of Bac Ninh 3 220/110kV substation. These activities could cause negative impacts to environment and local communities during the period of preconstruction, construction and operation. To ensure the potential negative impacts are identified and mitigated during the implementation period of the subproject and to comply with the Bank s Policy on Environmental Assessment, an (EMP) of the subproject has been prepared in compliance with the Environmental and Social Management Framework (ESMF) of the TEP and in connection with the subproject EIA. This EMP is an instrument that details: a) all anticipated adverse and social environmental impacts; b) the mitigation measures to be taken during the implementation and operation of a the subproject to eliminate or offset adverse environmental impacts, or to reduce them to acceptable levels; c) monitoring objectives and type of monitoring with linkages to the impacts assessed in the EIA report and the mitigation measures described in the EMP; d) the actions needed including institutional arrangements to implement these measures; e) capacity development and training to support timely and effective implementation of environmental project components and mitigation measures; and f) implementation schedule and cost estimates for implementing the EMP. The mitigation measures proposed in the EMP shall be integrated into the bidding and contractual documents, and monitored and supervised during all the phases of subproject implementation and operation. According to Vietnam s environmental assessment regulation, the subproject is subject to prepare an EIA for submission to the Ministry of Natural Resources and Environment (MONRE) for appraisal and approval. The report on EIA was submitted to MONRE in February 2014 and was approved by MONRE under the Decision No.919/QD-BTNMT on 05 th May II. POLICIES, REGULATIONS AND INSTITUTIONAL FRAMEWORKS 2.1.

The subproject has also to comply with the WB s requirements on public consultation and Policy on Access to Information. The implementation of the policy on Involuntary Resettlement (OP/BP 4.12) is addressed in the Resettlement Policy Framework (RPF) of the TEP project and the Resettlement Plan (RP) of this subproject. Environmental Assessment (OP/BP 4.01): Environmental Assessment (EA) is an umbrella policy for the Bank s safeguard policies. The overarching objective is to ensure that Bank-financed projects are environmentally sound and sustainable, and that decision-making is improved through appropriate analysis of actions and of their likely environmental impacts. The EA process is intended to identify, avoid and mitigate potential impacts of Bank operations. EA takes into account the natural environment (air, water, and land); human health and safety; social aspects (involuntary resettlement, indigenous peoples, and physical cultural resources); and transboundary and global environmental aspects. EA considers natural and social aspects in an integrated way. This subproject triggers OP 4.01 because it involves the installation and operation of a highvoltage substation, requiring the identification, mitigation and monitoring of potential adverse environmental and social impacts. As required by OP 4.01 and the government EA regulation, the subproject has prepared an EIA and an EMP that meet the Government s and the World Bank s safeguards requirements. By the TEP appraisal, the subproject EIA and EMP have been disclosed locally at the subproject sites as required by OP 4.01 and the Bank s policy on access to information. Involuntary Resettlement (OP/BP 4.12) Page 6

9 The Involuntary Resettlement policy seeks to prevent severe long-term hardship, impoverishment, and environmental damage to the affected peoples during involuntary resettlement. OP 4.12 applies whether or not affected persons must move to another location. The Bank describes all these processes and outcomes as involuntary resettlement, or simply resettlement, even when people are not forced to move. Resettlement is involuntary when the government has the right to expropriate land or other assets and when affected people do not have the option to retain the livelihood situation that they have. This policy is triggered because the subproject would have impacts involving the temporary and permanent involuntary taking of land and the loss of structures and assets associated with the land for the power towers and the right-of-way of the transmission line. By appraisal, the subproject has prepared and disclosed a RP locally at the subproject sites and at the Bank s InfoShop. The RP includes the measures to ensure that displaced people are: (i) informed about the options regarding resettlement; (ii) consulted and offered alternative resettlement choices; and (iii) provided with effective compensation and livelihood restoration. The final subproject final RP will be disclosed locally at the subproject sites, at the Bank s InfoShop, and the Vietnam Development Information Center. Physical Cultural Resources (OP/BP 4.11): Physical Cultural Resources Policy (PCR) is intended to ensure that projects identify and inventory cultural resources that are potentially affected by the project. PCRs include resources of archaeological, paleontological, historical, architectural, religious, aesthetic or other cultural significance. Projects should include mitigation measures when there are adverse impacts on physical cultural resources. Appropriate agencies, NGOs and universities should be consulted. OP 4.11 will be applied to this sub-project because the subproject would involve the relocation of seven (07) graves at proposed substation s location. Mitigation measures will be addressed in the respective subproject s RP. For this subproject, it is required that all construction activities will include mechanisms to address chance finds to avoid or mitigate adverse impacts on PCRs. Chance finds procedures have been prepared and included in environmental management plan of the subproject. These chance finds procedures shall form part of the safeguard procedures in the Technical specifications for Contractors. World Bank Group Environmental, Health, and Safety Guidelines World Bank-financed projects should also take into account the World Bank Group Environmental, Health, and Safety Guidelines 1 (known as the "EHS Guidelines"). The EHS Guidelines are technical reference documents with general and industry-specific examples of Good International Industry Practice. The EHS Guidelines contain the performance levels and measures that are normally acceptable to the World Bank Group and are generally considered to be achievable in new facilities at reasonable costs by existing technology. The environmental assessment process may recommend alternative (higher or lower) levels or measures, which, if acceptable to the World Bank, become project- or site-specific requirements. This subproject should conform the Environmental, Health, and Safety Guidelines for Electric Power Transmission and Distribution and the General EHS Guidelines. 1 The EHS Guidelines can be consulted at Page 7

SUBPROJECT ENVIRONMENTAL BACKGROUND 4.1. Geographical Location The subproject will be implemented in Yen Phong district, Bac Ninh province and Soc Son district, Ha Noi city. The connection line of the subproject will start at Bac Ninh 2 220kV substation in Cho town (center of Yen Phong district), run parallel with highway No.18, and ends at connection point in Kim Lu commune (in the Southeast of Soc Son district). This location is the gateway to the east of Ha Noi city and highway No.18. This is of great advantage to traffic and foreign affair in order to develop rapidly socioeconomic Climate, Topography, Pedology a. Climate Location of the subproject has a general characteristic of monsoon tropical climate, specifically the Red River Delta region. Average temperature is 30 C - 36 C and 15 C - 20 C Page 21

24 in the summer and winter, respectively. Cold season is from October to March of the following year. The weather is affected by the Northeast monsoon, which usually brings frosts and hoarfrost. Dry season is from April to October, and itis affected by the Southeast weather, which usually brings rains. Rain depends to the season. Annual rainfall is about 1,600 mm peryear. Rainyfall during the rainy season is accounted for 80% of the annual rainfall. Average air humidity is 83% per year. Sunny hour is 1,700 hour per year, which is favourable for rice crops, industrial trees, and other trees. b. Topography The subproject is located in the riverside plain region to the South of Soc Son district and the plain region of Yen Phong district. The elevation of the proposed substation location is from 3.9m to 4.5m and the elevation of the connection line in the field region is from 4.2 m to 7.0 m. c. Pedology The subproject location at Cho town, communes of Yen Phu, Hoa Tien and Soc Son is riverside plain region. This region has consolidated alluvium of Cau river and Ca Lo river; thus, the soil is rich and available for the cultivation of agriculture, farm products, and industrial trees within a short period (such as rice and crops) Situation of Technical Infrastructure a) Traffic Location of the subproject is the gateway to the east of Ha Noi city so the traffic infrastructure system is relatively developed. Highway No.18, Noi Bai international airport and Cai Lan port (in Quang Ninh) will run parallel with the subproject s location; this route will be 150m from the substation to the north and run parallel with the connection line and will be 50 to 91m from the subproject s location. In addition, a complete traffic system connected between the cities, provinces and economic region (in districts of Yen Phong and Soc Son). Road system connected between highway No.3 in Ha Noi and Thai Nguyen, highway No.18 and connection line route in Yen Phu commune. Provincial road No.295 to the north connected with highway No.18 at Cho town and highway No.1A to the south upgraded. Provincial road No. 286 to Bac Ninh province and Ha Noi was connected with highway No.3. Therefore, traffic condition is relatively advantage. b) Hydraulic Work Water sources used for agricultural cultivation at the subproject s location are taken from Cau river and Ca Lo river via irrigation and interior canals system. At location of the subproject has about 630m in length of irrigation canal. Section of this canal will be filled during leveling the substation so this canal will be restored around the substation s fence in order to supply and drain water for paddy fields surrounding the subproject s location. c) Domestic Water Sources People use currently local water system and well water to provide daily needs in Cho town and communes of Yen Phu, Hoa Tien and Kim Lu, respectively. Water for fire-fighting and daily needs of operators will use local water system in operation phase. d) Power Supply Currently, 100% of households in subproject s location have been used power source from the national power grid of the existing 220kV transmission line along highway No.18 via 22/0.4kV transformer installed on poles. Construction phase, the subproject will use the Page 22

25 current local power grid. In addition, the subproject will propose to construct a 22kV shunt line (about 200m long) from the existing 22kV transmission line along highway No.18 to substation and install a 22/0.4kV transformer on pole with nominated capacity of 3x25kVA in order to provide power in construction phase and testing equipment Land Use and Buildings on Land a) Land Use Total area of the subproject s ROW is 103,906 m 2, in which construction area of 19 tower foundations is 4,750.6 m 2. This area is mostly paddy field. Total construction area of substation and access road is 48,191 m 2. In which, access-road takes 11,416 m 2 ; this area is public road and will be returned to local authorities and managed by them after completion. A status of land use of this region in comparison with land acquisition area of the subproject is described in the following table: Table 4.1.

Paddy field around route of connection line b) Houses/Buildings on Land Affected by the Subproject Total residential area within ROW (11m from the center of line to each side) is 1,694 m 2. There are not any houses/buildings within permanent acquistion land area. There are four houses and buildings within the ROW. They will be limited height as stipulated in Article 13 of Decree No.14/2014/ND-CP. Table 4.2. House and building affected in ROW No. House Address Floor area (m 2 ) Floor area in ROW (m 2 ) Height of roof Materials of roof Structure Materials of wall Materials of floor 1 House Hoa Tien commune ,5 Tole Concrete Brick 2 House Hoa Tien commune Tole Concrete Brick 3 House Hoa Tien commune Tole Concrete Brick 4 House Hoa Tien commune Tole Concrete Brick Height of the existing houses and buildings in ROW is from 4 to 13.8 m. The average height is 6.6 m. Designed heigth of the transmission line will be at least 18m and 6m to ensure distance from the lowest point of wire in the maximum sagging state to natural surface of ground and from any parts of house/building to the nearest wire, respectively. The current house and building will be rehabilitated and grounded to ensure safety condition for existence of them within 220kV ROW. Therefore, the existing houses will not cause displacement and relocation. Page 24

27 c) Grave in Construction Area of Substation Figure 4.5. Two houses near to tower No.9A There are seven (07) graves located in the construction area of Bac Ninh 3 220kV substation; the area of these graves is around 200 m2. This is the single graves, which existed on rice land for a long time. These graves will be moved to another location. During the leveling period of the substation, the subproject s owner will co-operate with People s Committee of Yen Phong district and Cho town for implementing relocation. Figure 4.6. Ground graves at proposed substation location 4.5. Environmental Baseline Data In the investment project stage, the subproject s owner will take samples and analyze the quality of the physical environment (including quality of air, noise, surface water, underground water, and etc.). These measurements will be the standards in identifying and evaluating components of the physical environment for the subproject area Air Environment Quality and Noise The air sampling indicates the air quality is quite good in the subproject location. Most of the pollution criteria obtained at the sampling location of the substation and connection line met Page 25

28 permissible limits according to QCVN 05:2013/BTNMT National technical regulation on ambient air quality Water Environment Quality a) Surface Water Quality Surface water sampling at interior canals of the subproject location shows there are signs of pollution and microbial contamination. This also shows that some specific surface water in the agricultural region will be highly impacted by the amount of fertilizer which will pollute the high nutrient content in water. Other pollution criteria such as ph, suspension of solid substance, oil, and etc. have met the permissible limits of the QCVN 08:2008/BTNMT National technical regulation on surface water quality. b) Quality of Underground Water According to the result, the quality of the underground water at certain wells of households in the subproject s location is fairly good. Thus, the permissible limits of pollution criteria are met according to QCVN 09:2008/BTNMT National technical regulation on underground water quality. However, due to the effect of geology in local region, iron contents in underground water at the sampling locations have exceeded lightly in comparison with the stipulation from 1.09 to Socio-economic Status Economics a) Yen Phong district The Gross Domestic Product (GDP) of Yen Phong district in 2013 is around 6,000 VND billion, an increase of 11% since The average income per person is 28 million VND each year. The economic structure continues to grow and attract new investments into the zone. Industrial zones have increased rapidly with a participation of nearly 100 domestic and foreign enterprises. This will increase the number of employees to over 52 thousand people in the region. b) Soc Son district The output value of Soc Son district has an estimate of an increase of 6.84% in Its value will be higher in comparison with the planed criteria but will increase in the following quarter. Industrial and handicraft fields have increased 7.15%; basic construction has increased 6.84%; trade and services has increased 12.06%; agriculture forestry fishery have decreased 0.65% in comparison with Economical mechanism will grow positively. Trade and services will increase and agriculture products will decrease in ratio. Per capita income is estimated to be 23 million VND per year Culture and Society a) Population Soc Son district The population of district is about 300,000 people with 75,000 households, of which 44,000 households are accounted for 58.7% of agricultural production. The population density is 992people/square kilometer. The district has implemented vocational training and created 14,000 labors in the past five years ( ). The rate of created labors will increase to 33.73% in Page 26

29 Yen Phong district The population of the district is about 139,100 people. The population density is about 1,436 people/square kilometer. Elderly working population is about 88,212 people, of which 6,482 people are working in the zones or industrial zones. There are 6,324 people working in enterprises of the district region. Also, there are 636 labors which involve in working in foreign country and the remaining are the agricultural labors. b) Ethnicity The subproject s location (Yen Phong district, Bac Ninh province and Soc Son district, Ha Noi city) is the oldest settlement of the Kinh ethnic group. This is the main ethnic group of Vietnam. The subproject s location does not exist any other minority ethnic group. c) Culture and Society Issues around the culture and society within the subproject s location is the local authority s main concern. The subproject will contribute directly and indirectly into the improvement of living standard for the local people, such as supplying power for production, development of econimics, the lighting of all public works, and etc. The subproject is not in area of historical area, cultural heritage site, social-culture structure, nor national defense. V. POTENTIAL IMPACTS The screening of the environment around the subproject areas indicate that it is eligible for financing with an exception that the subproject will not involve possible high risk and will not create potential adverse impacts on: (a) critical natural habitats and/or protected area including proposed protected areas; (b) loss or damage to cultural property, including sites having archeological (prehistoric), paleontological, historical, religious, cultural, and unique natural values; (c) water regime, particularly water flow; and (d) other significant environmental and social impacts. The subproject will bring about positive changes to the local and regional economies and creating favorable conditions for local production activities and other social benefits. The implementation of the subproject would mainly cause land acquisition, increased dust generation, air pollution, domestic waste, and health and safety issues due to construction activites and electrical magnetic field. However, these impacts are not significant, temporary, and localized with available mitigation measures. So the subproject has been categorized as a Category B project according to Policies of OP 4.01 and satisfied to use the World Bank s loan. The potential negative impacts of the subproject are identified in Table 5.1. These can be minimized by applying the proposed mitigation measures which has been developed for the subproject in Table 6.1. Page 27

30 Table 5.1. Potential negative impacts of the subproject No. Impacts Pre-construction phase 1 Location of the subproject 2 Permanent land acquisition and affected land in the ROW Significance of impacts Impact duration Impact Description Small Short-term The subproject s location is not near or in cultural heritage sites, nature reserves or buffer zone of protected areas, wetlands, estuaries, nor forests. However, the subproject s location will affect the land and cultivation activities of 63 households, whose land will be permanently acquired by the subproject. In addition, Ca Lo river, lake, and Highway No.18 will cross the connection line. Impacts at the intersection will take place during the preconstruction and construction stages. These impacts will be minimized during the implementation. Moderate Short-term and longterm Area of permanent land acquisition is 52,941,6m 2, in which construction area of substation is 36,775.0 m 2. Access road area is 11,416.0 m 2. Tower foundation area is 4,750.6 m 2. Area of rice field is 42,637.6 m 2 ; it accounts for 85% of total affected area. Area of crops land is 1,390 m 2 ; it accounts for 2.6% of the total affected area. Irrigation canal land is 6.536,0 m 2 ; it accounts for 12.3%. Local road is 2,178.0 m 2 ; it accounts for 4,1%; Area of grave land is m 2 ; it accounts for 0.4% of total affected area for construction of the project. Residential land and house don t exist in permanent land acquisition area of the subproject. However, 63 houses will be permanently affected by the subproject. There are seven graves with a land area of 200m 2 located in the substation. These graves had existed for a long time and they will be moved to another place. In addition, the overhead connection line also affects the use of land in the ROW with area of 99,155 m 2. Most of areas affected by the ROW is rice land. Rice fields do not violate the safety distance from the conductors to land surface; thus, the local people can cultivate in the ROW without any impacts. There are four houses in the ROW with metal roofs. These houses will continue to exist in the ROW when they comply with a roof-grounding to ensure a safety for the project. The land acquisition will affect 63 households, whose land is in the proposed substation and the connection line. However, there are not anyhouseholds to be moved by this acquisition. Additionally, according to the investigation and collection from rice activities Page 28

31 No. Impacts Significance of impacts Impact duration Impact Description of these households, the land acquisition only reduces one portion of total their income. Most of them has obtained other income from non-agricultural activitives. Site clearance will be implemented after the harvest season to reduce damages to crops. In addition, according to the statistical report on socio-economic, the economical mechanism at the subproject s location is being grown in the industry as well as trade and services. Many industrial zones are being established and attracted investors to Bac Ninh province. Many works of the industrial field are being grown each year. Therefore, a heavy burden of the local authority in finding a new job for workers who are impacted by the acquisition will be minimized. The cultivation land acquired will affect local people; however, these impacts can be minimized through measures of compensation and assistance according to the stipulation of the Government to ensure their life and security. 3 Temporary land acquisition Small Short-term The land acquisition will be temporarily acquired during the subproject s implementation such as storage of materials and equipment and stringing wire. This land will be recovered after completing the subproject. This land locates in the ROW and it does not affect life of the local people. Land acquisition area for construction of a connection line is summarized as follows: - Temporary land acquisition for tower foundation is 6,483.6 m 2 - Warehouse, storage of equipment and materials is m 2 - Stringing wire: 800 m 2 Construction and storage of equipment and materials will be implemented at the substation so it is not necessary for expanding a temporary land area. Construction at each tower foundation location only lasts from one to two months so the temporary acquisition for construction only affects a crop. Page 29

32 No. Impacts 4 Effects on vegetation and habitat area due to site clearance 5 Effects on irrigation canal and local road in substation s location 6 Risk on healthy and environment due to explosive and chemnical substance 7 Impacts on historical area and cultural heritage site. Significance of impacts Impact duration Impact Description Small Short-term Vegetation is mainly rice at the subproject s location. Site clearance will be done after harvest season so the vegetation is mainly rice stubble. Wheat plant is low and harvesting period is short so they can stay in the ROW without being chopped down. Land clearance only includes area of construction and temporary acquisition plan. Generally, these clearance activities at the substation and connection line is assessed as a minor impact and mitigable. The affected trees mainly get an economical value without ecological one. Moderate Short-term At proposed substation location has interior canals with 630m in length and 2-4.5m in width; these canals is used for irrigation of the surrounding rice field and area of them is 6,536 m 2. Local road runs along with irrigation canal, which is used to access rice-field of local people. Length of this local road is 630m and affected area by the subproject is 2,178 m 2. These canals and local roads will be filled prior to construction of the project so they will cause a clogging of irrigation system and as well as a stopping of entrance to local road of people. This affects the production of farmers around the proposed subproject location. Therefore, these canals and local roads should be re-establised before leveling the substation s site. Small Short-term The subproject does not use chemical and explosive substances for clearance and leveling. However, according to the opinion of the Bac Ninh province Military Command, the subproject s location can also remain unexploded ordnance underground, and they can explode in case of having collision between them and construction equipment. This will cause accident for workers and damage assests of local people. Therefore, the subproject should prepare a removal plan for unexploded ordnances to ensure safety prior to construction. Moderate Short-term The subproject s location is not near to or in historical area or cultural heritage site. However, there are seven ground-graves in the proposed substation location. Relocation of graves can cause effects on spiritual life of households, who owned them if the relocation does not do properly with the local customs. But this is the ground-graves, which was existed for a long time so they ensure time for reburing according to local customs. Page 30

33 No. Impacts Construction phase 8 Effects on air quality due dust generation, exhaust gas from construction vehicles and transportation means 9 Impacts from noise and vibration 10 Increase water turbidity due to run-off and erosion Significance of impacts Impact duration Impact Description Moderate Short term Dust will generate during construction such as excavation, backfill and transportation. This dust is mainly generated from ground and it is easy to accumulate in a short time. This source will be generated temporarily during construction phase. The subproject locates in the agricultural region so its impact is small. Dust and exhaust gas are generated from activities of engines of transportation means and machineries. These means are used the clean-fuel so pollution content of waste gas is not high. Effects on the waste gas are not significant in the subproject region because generated location is mainly in rural region. At section G5A G5C of the subproject crosses over the residential region of Hoa Tien commune. This location will bear strictly air pollution, the remaining locations of connection line cross over the agricultural region so the effects on air pollution is small. Small Short term Noise and vibration can be caused by transportation means and mechinaries. However, construction activities are mainly carried out manually or semi-mechineries with a small means so the intensity of noise is not high. Most of the construction locations are located in the rural region, away from residiential region. The region caused strictly noise is the foundation locations crossing over the residential region in Hoa Tien commune; section G5A G5B has the foundation near the local house. Moderate Short term Ground and sand sweep away by the surface water flow at construction location can cause erosion and increase turbidity. Especially, the subproject will mainly be located on agricultural land with many interior canals and connection line will traverse Ca Lo river and it also intersects two times with the lake. However, it is assessed as a small impact because towers of this connection line will be 50m and 30m away from river and lake edges, respectively. Terrain of the subproject s location is flat. The construction period is short. The construction site will provide pits and trenches for water drainage surrounding the tower foundations. Quantity of excavation will be stored and maintained in a short time Page 31

34 No. Impacts 11 Impacts on environmental quality due to water waste. 12 Impacts on environmental quality due to waste. Significance of impacts Impact duration Impact Description and they can reuse to fill foundation after completing concrete work, and it also uses for filling slope work. The subproject will not construct towers on river, lake and canal so impacts causes by erosion, run-off are assessed as moderate. Moderate Short term Worker at the site is 80 persons in construction duration. Volume of domestic wastewater will estimate 9.3m 3 /day. This volume would generate at tents of the substation and connection line. However, these tents are far from canals and domestic wastewater only generates in the construction period and rural region so impact on wastewater is not significant. The wastewater is assessed as small and mitigable. Apart from the domestic wastewater, during the construction period, the subproject also generates construction wastewater, including pump pit drainage and a little capacity from equipment and machinery s sanitary during construction. This volume only happens in the construction duration and component of the pollutant in waste water is mainly soil, sand, non-hazardous substances. The soil and suspended-sand mixed in water will be easy to deposit sediment in the temporary drainage trenches. Therefore, impacts on waste water are as moderate. Moderate Short term The amount of generated waste is 48kg/day for total 80 persons of the whole subproject in construction duration. These amounts will be allocated at the two tents. Quantity of waste is small; it does not contain hazardous components. This waste will be collected and handled properly so it will not cause negative impacts on environment, unsanitary and effect on the surrounding aesthetics. Quantity of excavation will be reused for backfill work. Thus quantity of redundant soil is small. These quantities will be fully utilized to slope banks against erosion in the tower foundation of the connection line and do slope work at the substation. Redundant quantity is small but if the contractor does not collect and store them properly; it will cause negative impact on environment. In the process of construction and installation of the subproject can generate a lot of construction wastes such as concrete debris, formworks, steel scrap, crates, and etc. Page 32

35 No. Impacts 13 Water and soil due to hazardous waste 14 Soil erosion and eboulement generation caused by excavation, leveling and fillback duration Significance of impacts Impact duration Impact Description However, most of these construction wastes can be recycled and reused so it would be easy to control and collect this waste. The waste substance will be collected and treated according to stipulations of solid waste substance and the implementation schedule is short term (15 months). Thus, the generation of solid waste substances is assesses as moderate and mitigable. Small Short term Hazardous waste is mainly oil and oil rags, which will be generated from activities of maintenance of equipment, machineries and transportation means in the construction process. The waste oil volume generates from 41 construction means will be estimated about 287 liters/time, around liters/month. This volume only happens at the maintenance agents and they are collected by these agents. Therefore, this waste oil volume is low at construction site; it only happens when having samll repairment at site. Waste oil and oily rags can collect strictly, store and streat safely so these impacts are assessed as small. Moderate Short term Excavation, backfill, leveling and construction of the subproject will change structure of soil surface, it will cause a soil erosion due to rain-water run off or wind. Specially, substation base is filled higher than the natural ground level of 1.84m so if the contractor has not a suitable measure for reinforcing the substation base, and then risk of landslide will happen and can affect the surrounding rice-field. Construction of pole foundation can cause a erosion of canal edge at location near canal and river. This will reduce the capacity of the natural drainage in the regional location if it is not properly managed. Especially, the connection line will traverse one time via Ca Lo river and twice via the lake. However, the subproject s terrain is flat and the construction its construction always meets stipulations on safety distance at the location near to canal. The contractor will apply reinforcement measures to protect soild erosion during the leveling and excavation of foundation pit. The total quantity of excavated soil would utilize to slope and backfill foundations and substation plan. In addition, river and interior canals in the subproject s Page 33

36 No. Impacts Significance of impacts Impact duration Impact Description region will be reinforced by the protection wall. 15 Impacts on road Moderate Short term Transportation, storage of equipment and materials at the site would affect local traffic and installing tower and stringing wire at the cross section would interrupt traffic for a short period of time only. 16 Impacts on waterway traffic The substation would locate near Highway No.18, this location will be 150m from road edge and the connection line will be 50-90m from road edge so transportation of equipment and construction materials from Ha Noi city and local agents to the site is benefited by Highway No.18. Therefore, transportation would not effect significantly to local traffic. In addition, traffic activities will be affected by stringing wire work via road at intersection section (Highway No.18 and Highway 3). However, the contractor will provide scaffold to limit affects of local traffic during stringing wire. Traffic affects can also happen at the rush hour during construction of tower foundations at the residential region of Hoa Tien. None None Connection line will intersect one time with Ca Lo river, the width of this river is 48m; and twice with the lake, its width is 63m and 67m. Activities of stringing wire at section via river can interrupt waterway traffic from one to two hours. However, cross section at Ca Lo river and the lake does not exist the waterway traffic. Therefore, the subproject will not affect the waterway traffic. Local people sometimes use small boat to fish in the Ca Lo river, but its activity does not happen regularly in section of the subproject s location because river fish currently is small. During the stringing wire, these boats can be affected at section across the river. However, period of influence is short so effects on boat in the river is assessed as a minor impact. Page 34

37 No. Impacts 17 Effects on house near to section of G5A G5B 18 Effects on local traffic system quality 19 Effects on health and safety from camps and spread of infectious diseases Significance of impacts Impact duration Impact Description Moderate Short-term There are four houses located at section of G5A G5B in Yen Vy village, Hoa Tien commune, Yen Phong district. Two of them is near to location of tower foundation; it is tower location No.9A. Distance between them is at least 20m. They are the fourth grade house, brick wall, tole-roof with height of 4-4.5m. People lived in these houses will be affected by noise and dust from construction activities. Structure of house can be affected by shock from piling activity and landslide from excavation work. However, this is a house without upstairs (single house); its height is low so negative impacts from these activities is small. Landslide during excavation can be minimized by techinical method in construction duration; and then impacts on noise and dust can be also minimized. Small Short term The transportation of materials with the high frequency can affect the rural road system in the local region. The substation is 150m from Highway No.18 and the subproject will contruct an access road for transportation of materials during construction and use for operation period. The tower foundations of the connection line is 50m - 90m from Highway No.18 so materials will be transported by manual means to the site. Highway No.18 is designed to bear a heavy load so the transportation of equipment and machineries for the subproject will not affect significantly. Transportation activities would be carried out by manual means from Highway No.18 to the site, therefore, the transmission frequency mostly increase low on the paths with bad quality. The subproject s activities will rarely affect these paths. Nowadays, government authorities and local people closely monitor traffic management at the local region. The means a weight load exceeding the limit will not be permitted access to the local roads. This is also an issue for the contractor who must meet and carefully propose the transportation solution and avoid damaging the local roads system and edge of rice field. Small Short term Total workers are 80 persons at the subproject s site. Sanitary condition and safety at the tents and the site can affect the worker s health. However, these works will be paid attention by the contractor and these workers will be managed and checked periodically on health. Therefore, the disease transmission from the worker is assessed as small because Page 35

38 No. Impacts Significance of impacts Impact duration Impact Description this transmission would be treated by prevention measures. 20 Conflict between construction workers and local people 21 Accident risks to workers and community Small Short term Conflict between workers and local people can happen due to difference of income, culture and behavior. Living period of worker at the site is short (maximum of 15 months). The estimated workers at the site is 80 people, in which, it is proposed 30% of the total labor workforce will be local residents. Most of the non-local workers are technical labors who have extensive construction experience. Therefore, the conflict between non-local workers and local people and community are expected to be minor. Moderate Short-term Accident risk can happen in construction duration if the contractor is not paid attention to safety measures. Accident can happen due to foundation excavation, crane operation, tower erection and stringing wire, and etc. Accident can also happen to the construction workers or local people surrounding the subproject. Particularly, workers do works at height and install equipment on overhead poles; the posibility of accident is large when the contractor does not provide labor protection measures appropriately. Effects on health due to accidents is high and death from these accidents for victims is very high. However, according to the current stipulations, labor safety measures will prevent and solve accidents in the construction duration. Therefore, it will minimize accident risks. 22 Interruption of services Small Short-term During construction process of the substation and the connection line, it is necessary to deenergize some regions so it willinterrupt some services using power network. However, this de-energizing work only happens at the end construction period when this line is connected to the power network. The estimated de-energizing time is from one to two hours. Operation phase Page 36

39 No. Impacts 23 Effects on environemental quality due to domestic waste of operators 24 Effects on environmental quality due to hazardous waste 25 Impacts due to noise of the transformer Significance of impacts Impact duration Impact Description Small Long term Operators estimates about 22 persons at the substation during operation, these people will be divided into three shifts and five groups. The substation operation activities will be carried out according to shift regime, the actual number of operators is 7 persons per shift in maximum. Operator s activites will be generated a little volume of the domestic waste water and solid waste. The volume of domestic waste water of the operators is about 0.84 m 3 /day. The quantity of domestic solid is about 4.2 kg/day. Waste water and solid waste of the operators will generate with the small quantity so they will not affect to environment. Waste water will be collected and properly treated by septic tank before discharging into sewerage source. Domestic waste will be collected strictly and stored temporarily in bins at the site after that they will be moved by sanitation agent in local region. Small Long term Hazardous waste generates during operation period is mainly oil leakage of the transformer and oily rags. Oil of the transformer is fixed the interior of its one or capacitor and used to cool or hold a function as an insulator so oil the transformer will not generate into the environment. However, the oil can leak in the operation, repairment and maintenance processes of the transformer, or the oil leakage can also happen in the process of oil change. In addition, maintenance and santitation processes of the transformer will also generate oily rags and this quantity estimates about kg/month. Oil of the transformer is mineral component with a long existence, it will affect to the environment in case of leakage. But the transformer does not ensurely contain any hazardous components of PCBs. Oil of the transformer and oily rags can collect strictly and safely store and they will be transferred to the relevant agents for treatment. Small Long term As the technical result of 220kV transformer, they are designed according to the international standard (IEC standard), the noise is around 76 dba at distance of 2 m, so it meets permissive limit (85 dba) on noise in productive region issued at Decision No.3733/2002/QD-BYT. In reference with the monitored data which is being operated at 220kV substations, the noise is 70 dba at distance of 6 m to the transformer location, it meets value as mentioned in QCVN 26:2010/BTNMT maximum limits on noise in the production region at 6 a.m to Page 37

40 No. Impacts 26 Effects on health due electromagnetic field 27 Effects on telecommunity system 28 Risk on electric shock to health of workers and operators and local people around the high voltage Significance of impacts Impact duration Impact Description 9 p.m. Therefore, the noise only affects to operators, but its impact is a small, it will not affect to their hearing and health. Small Long term The substation and connection line are designed according to electrical standards and met stipulations on safety at Decree No. 14/2014/ND-CP. And then, the connection line is designed with suspension height that will ensure maximum electric field intensity. The electric field intensity should be less than 5kV/m in the ROW at the height of 1m above ground level as stipulated in Clause 2, Article 7 of Decree No. 14/2014/NĐ-CP. In reference the monitored value of electric field intensity at some locations of 220kV substation which is being operated, it was shown that value of electric field intensity is more than 5kV/m at the location of circuit-breaker and transformer. But there are not any locations in the substation that its value is over 25kV/m maximum permissive limit of the electric field intensity in working environment as stipulated at Decision No.3733/2002/QD- BYT of Ministry of Health. Therefore, the substation s operators can access to working locations in the substation when meeting time as stipulated at Clause 2, Article 7 of Decree No.14/2014/NĐ-CP. None None Communication system can be affected by the subproject, including communication line is near the substation and radio communication centers. However, the impact is calculated and considered according to the current stipulations when designing the subproject so this impact is assessed as a minor. The phenomenon of corona on surface of wire was designed according to IEC and TCVN standards to limit properly effects to radio and television communication. Moderate Short term Design of the subproject focus on safety measures. Network risk and accidents can happen in operation phase if the workers do not comply to the safety rules or local people do not meet the safety stipulation on power network. 29 Fire hazard and oil- Moderate Short term Oil overflow will not be significant since the transformer is operated in a normal condition. Page 38

41 No. Impacts overflow of the transformer 30 Hazard on collapsed tower Significance of impacts Impact duration Impact Description The oil over-flow only occurs when the transformer meets risks such as fire, which the transformer should be paid close attention to during the operation. Fire hazard can happen in many different reasons. They can occur inside or outside of the transformer and can be increase the risk to high. However, the substation has designed a fire-fighting system for the transformer. If fire occurs, the fire-fighting system will alert with signals and extinguish the fire automatically. This will prevent the fire from spreading to the outside location of the transformer and outside of the substation s gate.. Therefore, transformer s risk will not impact to the surrounding of the substation. In addition, the substation also provides a pit to collect all oily leakage volumes if any. Moderate Short term Towers of 220kV transmission line can be collapsed by lighting, wind, or storms. Weak foundation, especially at towers in flooded location can cause the transmission line to collapse as well. However, design and supervision have been implemented will and met safety standards. Tower foundation is designed on the basic of topography conditions, geology, and hydrometeorology of the region. Its design withstands against natural elements as statistics has shown over the last 20 years. Page 39

42 Conclusion: The implementation of the subproject would mainly cause land acquisition, increased dust generation, air pollution. However, these impacts are not significant, temporary, localized impacts with available mitigation measures. Therefore, the subproject is assessed as B environmental category in accordance with the WB s criterion and eligible for funding by Transmission Efficiency Project. Page 40
