EXECUTIVE SUMMARY 1. The Government of Socialist Republic of Viet Nam (GOV) has requested the Asian Development Bank (ADB) to provide financing for the development of the 220kV/110kV Phu My Substation and Connection Lines project. The National Power Transmission Corporation (NPT) of Viet Nam will be the executing agency (EA) while the Southern Power Project Management Board (SPPMB) will be the implementing agency (IA) of the project. 2. The project is one of the subprojects proposed for financing by NPT under Tranche 1 of the Multi-tranche Financing Facility (MFF). 3. The proposed project aims to:

(i) meet the demand for power of the load growth zone 2 of the Ba Ria – Vung Tau province with a total land demand of 186MW in 2007 and 501MW in 2010;

(ii) ensure reliability and quality of power; and

(iii) reduce power losses in the transmission system. 4. The project includes the following components:

(i) Construction of the 220kV substation and access road with a total area of 55,013 m2;

(ii) Construction of the 220kV transmission line with a total length of 1,707 m; and

(iii) Construction and installation of two parallel 110kV transmission line which are 40 meters apart and with a length of 831 m and 912 m, respectively.

5. Based on Viet Nam Decree No. 21/2008/ND-CP, the project is required to prepare and submit a Commitment Report to Protect the Environment (CPE) to the Department of Natural Resources and Environment (DoNRE) of the district where the project is located. A Certificate of Registration on Commitment to Environmental Protection for the project was issued by the People’s Committee of Tan Thanh District on 08 April 2008 (Appendix 3). A separate Initial Environmental Examination (IEE) report was prepared for the project in February 2011 by the Power Engineering and Consulting Joint-stock Company No. 3 (PECC3) for submission to ADB. 6. Based on ADB’s Safeguard Policy Statement 2009 (SPS), the proposed substation and connecting lines project is categorized as “Category B” project which requires an IEE. The preparation of this IEE is guided by the requirements outlined in SPS. Information in the IEE is based on the IEE prepared by PECC3, secondary data from other agencies, field inspection and information gathered during community and stakeholder consultations. The objectives and scope of the environmental impact assessment are to (i) establish current environmental conditions; (ii) identify key environmental issues; (iii) assess magnitude of impacts and provide mitigating measures; (iv) integrate the environmental issues in the project planning and design stage; and (v) develop an updated environmental management plan for implementation, monitoring and reporting of the environmental mitigation and enhancement measures.

7. Consultations with affected communities within the proposed site of the substation and along the alignment of the connecting lines have been carried out by SPPMB and PECC3 team in March-April 2011 at the Tan Phuoc commune of Tan Thanh District. Issues that were discussed during the consultation meeting included impacts on air quality, noise, water quality, socio-economic activities, and mitigation measures to address these concerns (Appendix 4). 8. The evaluation of the pre-construction, construction, and operational phases of the project components indicates that the project will generate minor adverse impacts to the environment that can be reduced to acceptable levels through the implementation of mitigation measures associated with internationally recognized engineering practices. 9. There are no significant sensitive areas that will be affected by the proposed construction of the 220kV substation, access road, and connection lines. The sites were selected to avoid environmentally sensitive areas, settlements, forests, and cultural/heritage sites. The vicinity is generally characterized as a grazing land. Photographs of project site are in Appendix 5. 10. The impact of the project on agricultural land comprises the loss of 182,110 m2 of flat, agricultural land that is being used to plant rice and other crops. There are no trees in the affected land. Compensation for the loss of agricultural production will be paid to the affected households according to the resettlement plan. 11. During the pre-construction phase, the design of the project should take into consideration the geologic hazards such as liquefaction, soil stability and earthquake and seismic potential of the area. In addition, the project site is near the estuary and coastal area and salinization may be expected, aside from potential corrosion effects of industrial plants in the vicinity. Salinization and air pollution may cause damage to the steel towers and other facilities of the substation and connection lines. In order to protect the high voltage insulator lines from air pollution (particulate matter, salt content, etc.) in the area, a creepage distance of 31 millimeter per kilovolt (mm/kV) is to be applied in the design. These insulator lines are designed according to the Electrical Equipment Standard 11 TCN-19-2006. 12. The impacts of the project during the construction phase are limited to the surrounding area and can be readily mitigated. The adverse impacts likely to occur during the construction phase are considered temporary in nature and could be mitigated through proper design and implementation of the proposed mitigation measures. The impacts during the construction of the project are primarily due to the clearing of the existing vegetation, earth filling at the substation site to prevent inundation, and construction safety. These are briefly described in the following paragraphs:

(i) The substation will be located in an area that is flood-prone and is near an estuarine characterized with mangroves, hence, will require earth-filling to raise the elevation of the site. The design of the drainage plan will take into consideration the increased runoff and soil erosion from the site. Engineering controls for erosion protection measures such as silt traps and sedimentation ponds will be integrated in the management plan.

(ii) The substation site is also near a gas transmission pipeline. Extra caution will be observed when constructing the connection line towers in the vicinity of the gas transmission pipeline.

11

(iii) There will be water pollution, sanitation, and health hazards due to presence of workers camp. Adequate water supply and toilet facilities will be established at the existing construction camp.

(iv) A construction health and safety plan shall be required from the contractor, including

provision of first-aid facilities to provide measures and procedures in addressing occupational health and safety at the construction site.

(v) The movement of construction vehicles along the access roads would contribute to the

increase in ground level concentration of total suspended particulates (dust), noise, and could also result to accidents and hazards to communities living along the access roads. Measures such as limiting of construction hours and deliveries to the site at night and imposition of speed limit to vehicles will be implemented.

(vi) Impacts related to community health and safety such as construction traffic, transport of

materials, fires, emergency spill of materials, and unauthorized entry by the villagers into dangerous working areas will be mitigated through the development of a Community Health and Safety Plan (CHSP) that incorporates good international practice and recognized standards that includes fencing of construction area, posting of warning signs in Vietnamese language, emergency response and preparedness procedures, communication systems and protocols, interaction with local and regional emergency and health authorities, provision of emergency equipment and facilities such as fire truck, emergency service vehicles, and fire drills will be established.

13. The impacts during the operational phase include the concern about electromagnetic field (EMF) and management of hazardous wastes at the substation and connection lines. The community and workers will be protected against electrocution hazards as a result of contact with high voltage electricity through the provision of signs, barriers, and gates/posts surrounding the towers, particularly in built-up areas. 14. An Environmental Management Plan (EMP) has been prepared and will be implemented during all phases of project implementation. The EMP identifies the potential environmental impacts from the project and includes institutional arrangements for its implementation to ensure its sustainability and effectiveness. An Environmental Monitoring Plan (EMoP) is also developed to monitor the important environmental parameters during the construction and operation of the proposed project. 15. The project will provide positive impacts to the community because the substation and connection lines meet the power demand of Tan Thanh district and the industrial zone of Phu My 2. It is also expected to contribute positively to the economic development of the northern region through the improvement of the Bai Ria-Vung Tau power grid and is expected to improve reliability and security of power supply that would allow SPPMB to meet the increased power demand in the region. 16. The SPPMB has an Environmental Officer within its organization to oversee the implementation of the EMP. The power company also hires the services of consultants to assist the company in the preparation of environmental reports, implementation of the EMP, and monitoring the environmental and compensation measures of the project. To increase the capacity of SPPMB to properly implement the EMP and EMoP, an Institutional Strengthening Program is developed for SPPMB. A training program addressing community and worker safety, EIA preparation and review, EMP implementation, inspection and corrective action,

12

environmental standard operating procedures, proper handling and disposal of spoils, protection of local vegetation and water resources, and avoiding impacts on local population from noise and dust-generating activities is proposed. 17. A Grievance Redress Mechanism will be established to receive and facilitate resolution of affected people’s concerns, complaints, and grievances about the project, particularly on compensation policies. It outlines the agreed upon compensation for land, property, trees, and other structures affected by the project based on consultations that were conducted with the affected villages. A grievance redress mechanism during construction and operation of the project was also developed to respond to people’s complaints. This will be supervised by the SPPMB and the decision will be based on the district and provincial level committees. For cases, wherein the complaint cannot be resolved in district and provincial level, the final decision will be at the People’s court.

II. POLICY, LEGAL, AND ADMINISTRATIVE FRAMEWORK

A. ADB’S ENVIRONMENTAL POLICIES 28. All ADB financed projects are required to undergo an environmental impact assessment. The SPS clarifies the rationale, scope and content of an environmental assessment. This is supported by technical guidelines as outlined in the Environmental Assessment Guidelines (2003). Projects to be financed by ADB are initially screened to determine the level of assessment that is required according to the following four project categories:

(i) Category A projects normally cause major environmental or social impacts that are irreversible, diverse, or unprecedented such as in hydroelectric dams. An EIA is required for this project.

(ii) Category B projects for which minor impacts are expected and can be mitigated. An IEE is required for this project.

(iii) Category C projects do not pose environmental or social impacts. No environmental assessment is required but environmental implications need to be reviewed.

(iv) Category FI projects involving investment of ADB funds to or financed through a Financial Intermediary.

29. The SPS introduces emphasis on the effective implementation of environmental safeguards. The objectives of ADB’s safeguards are to:

(i) avoid adverse impacts of projects on the environment and affected people, where possible;

(ii) minimize, mitigate, and/or compensate for adverse project impacts on the

environment and affected people when avoidance is not possible; and (iii) help borrowers/clients to strengthen their safeguard systems and develop the

capacity to manage environmental and social risks.1 30. The SPS contains a number of operational principles that includes the requirement to ensure that the measures identified during the impact assessment are included in the environmental management plan and were implemented in agreement with the borrower. 31. Under SPS the project has been evaluated considering the completion of the Environmental Categorization Form and REA checklist. The adverse environmental impacts of the project are considered site-specific and reversible. Therefore, it has been classified as Category B.

4. THE EIA PROCESS AND REQUIREMENTS IN VIET NAM 37. Based on Decree No. 21/2008/ND-CP, the project is required only to make a Commitment Report to Protect the Environment (CPE). The report is prepared by the investor and submitted to the Department of Natural Resources and Environment (DoNRE) of the district, where the project is located. The required report is a simpler form of Environmental Impact Assessment Report. The project is not required to:

(iv) be assessed by a Review Committee; (v) measure environmental condition; and (vi) conduct Public Consultation

38. The duration for processing the submitted report is five working days. Once approved, a Certificate of Registration on Commitment to Environment Protection is released for the project 39. Under the guidance of Decree No. 21/2008/ND-CP, Circular 05/2008/BTNMT, investors only need to obtain the said certificate. An environmental clearance is not needed. 40. Just recently, the Decree No. 29/2011/ND-CP was issued on 18 April 2011 as an amendment of the EA process. The new decree outlines the regulation on strategic environmental assessment, environmental impact assessment and environmental protection commitment and will take effect in September 2011. There are changes in the required document and processing duration between the decree No 21/2008 and No 29/2011. The categorization is now based on the voltage capacity of the transmission line, wherein projects located in more than one province and with voltage capacity greater than 110kV are now required to submit an EIA report to MoNRE. In addition, projects not implemented or

21

constructed within 36 months from issuance of the CPE or EIA will be required to submit a new application. 41. Since the CPE for this project was issued in April 2008, the CPE is already considered expired (Appendix 3). Under this new regulation, the proposed 220kV Phu My substation project will now be required to submit a full-scale EIA report to MoNRE. 42. EIA Requirements. The following are the required documents for EIA report:

(i) description of the project (Name, capacity, etc.); (ii) documents between the Government, ADB, Electricity of Viet Nam (EVN), and

the Acceptance Letter; from the provinces covered by the transmission lines; (iii) project investment and highest and lowest height of the line; (iv) map of monitoring sampling points/areas; (v) map of the routes covered by the transmission lines; and (vi) indexes (Climate, social, etc.)

Amplitude of the pendulum mass center cyclic vibration for Level VI ranges from 1.1 – 2.0mm. In this level, the earthquake intensity can be felt by people and some buildings could be slightly damaged.

75. Recorded earthquakes that occurred in the area were in 1923, in 1960, and on 20 December 2002 at Vung Tau. The 2002 earthquake had a magnitude of 4.1 – 4.8 and occurred for 3 seconds. There were no damages reported during this recent earthquake. 76. On 05 August 2005, another earthquake was reported at 8:30 pm. This was followed by another earthquake on the following day at 1:30am which lasted for 20 seconds. The most recent earthquake was reported on 08 November 2005 with seismic intensity of about 5.1 on the Richter scale. The epicenter was located about 100 miles of the Ba RIa – Vung Tau coast. No damage to property and human lives were reported.3 4. CLIMATE

77. The project area is located in the tropical monsoon area with two distinctive seasons: the dry season from November to April and the rainy season from May to November. The annual average temperature is 27oC, with the lowest temperature being 25oC and highest temperature 29oC. The coolest month is January and the hottest month is May. 78. The annual average humidity in the province ranges from 80% to 85% and rainfall from 1,600mm to 2,000mm. There are two prevailing winds: the northeast from September to March (winter monsoon) and the southeast from March to July (summer monsoon). The northeast and north wind dominates at dry season with the velocity around 1-5m/s; the west and southwest wind dominates at during the rainy season with the velocity around 3-4m/s. 79. The frequency of storm and flood in this province is rare. Ba Ria-Vung Tau province experienced ravages of three hurricanes about 200 years ago. Major storms experienced by Ba Ria-Vung Tau province occurred on October 5, 1876; May 1, 1904, and December 5 2006. 4

5. WATER RESOURCES

80. Surface Water: Surface water of Ba Ria – Vung Tau province is mostly supplied by the three rivers, namely, Thi Vai (25km), Ray (120km), and Dinh (30km). There are also three major lakes namely, Da Den, Ray, and Chau Pha.

81. Groundwater: Underground water of Ba Ria – Vung Tau is abundant. At 60-90 meters depth, the average flow discharge was reported as 10-20m3/s. The total reserves can be exploited is about 70,000m3/day which are concentrated in Ba Ria – Long Dien (20,000m3/day), Phu My – My Xuan (25,000m3/day) and Long Dat – Long Dien (15,000m3/day) and ensured to supply for demand of agriculture, industry and domestic.

6. MINERAL RESOURCES 82. Ba Ria – Vung Tau has abundant mineral resources. However, the most significant are petroleum, natural gas and minerals for construction. According to the total defined petroleum reserve, the coastal region of Ba Ria – Vung Tau has 400 million cubic meters petroleum (93.29% of the total reserve of the whole country) and more than 100 million cubic meters (16.2% the whole country’s reserve) The total potential reserve in 2000 around 2,500 to 3,500 million cubic meters, including 957 million cubic meters of petroleum and 1,500 million cubic meters of natural gas. 83. Minerals for construction are also quite diverse and include construction stone, devitrified stone, kaolin, glass sand, benotonit, peatcoal, immenit, and clay. These can be found in Tan Thanh, Long Dat districts, Ba Ria – Vung tau township and Vung Tau city.

7. AIR AND NOISE QUALITY

84. There are many practices and activities contributing to noise and air pollution in the vicinity of the proposed substation. The Phu My 2 Industrial Zone is located about 800m away from National Way No. 51, the main road from Ho Chi Minh City to Ba Ria-Vung Tau province. There are complex of power plants in Phu My Industrial Zone which is only 1.5 km away from the substation. The high pressure gas pipeline used for Phu My thermo-power plant has its route parallel with the entrance road of the substation. 85. The investments in Phu My 1 and Phu My 2 Industrial Zones are promising and there are many ongoing projects around the substation and there is a potential increase in levels of air pollutants in the vicinity. In order to protect the high voltage insulator lines from air pollution (particulate matter, salt content, etc.) in the area, a creepage distance of 31 millimeter per kilovolt (mm/kV) is to be applied in the design. These insulator lines are designed according to the Electrical Equipment Standard 11 TCN-19-2006.5

B. BIOLOGICAL RESOURCES

8. FOREST 86. Forestry area in Ba Ria – Vung Tau is not large. Forestry land is about 38,850 ha, occupying 19.7% total area of the province. The existing forest land is about 30,186 ha (natural forest is about 15,993 ha and cultivated forest is about 14,253ha). So far, there are about 8,664ha forestry land that has been used for other development purposes. 87. The province has two primieval forests, namely, Binh Chau – Phuoc Buu natural reserve (11,392ha) and Con Dao national park (around 5,998ha) which are important to landscape, environmental protection and tourism. The Binh Chau-Phuoc Buu natural reserve is located 35 km from the substation while the Con Dao National Park is situated 70 km from the substation. The Con Dao National Park is an island.

positive compared to the average 7.5% – 8% GDP growth rate of Viet Nam’s southeast. Ba Ria-Vung Tau is the country’s leading Foreign Direct Investment (FDI) destination, attracting the most FDI of provinces nationwide of around US$ 5.1 billion. As of 2009, total FDI in the service and tourism sector accounted for over 50% of the total FDI capital of the province. 10 95. Economic structure of province had rather grown quick, by 78% industry and 16% living activities agriculture in the last two years. Industrial production has averaged value out at 38% a year. The agricultural and cultivated area is 53,841 ha, which decreased to 1.8% in the same time of the last year. The import-export turn-over averaged at 28.9% per year.

96. From 2010-2020, Tan Thanh district plans to develop seven industrial zones with total area of 5,233ha including Phu My II, Cai Mep, Phu My II extension, Phu My III, Cai Mep Ha, Long Huong and Long Son.11

5. INFRASTRUCTURE FACILITIES

97. Water Supply. Supply water in the area comes from groundwater My Xuan and from surface waters of Toc Tien and Phu My with a total capacity of 40.000m3/day. These water sources supply the daily needs of the community and for production in Tan Thanh Industrial zones. There are still some households using drilled wells to tap groundwater source. The shallow groundwater levels affected by saltwater intrusion can be only used for washing. The communities surrounding the proposed substation buy clean water from other places for drinking. For the substation, domestic water will be obtained from Phu My 2 industrial Zone supply water.

98. Fire Prevention and Fighting System. The Tan Thanh District has a fire fighting station. Likewise, the Phu My 2 Industrial zone is equipped with a fire fighting station. The proposed Phu My substation plans to tap the fire station of Phu My 2 industrial zone in case of fire events. Furthermore, the substation will have its own water pumping station, water tanks, steel tube system, spraying system, hydrants, hoses and hand-held nozzles, CO2 gas tanks, and other ordinary firefighting equipment in accordance with the current standards.12

6. TRANSPORTATION 99. Ba Ria – Vung Tau’s transportation system consists of air transport, roads, harbors, railway and waterways that will be beneficial during the different project phases. 100. Road: The road network consisting of national highways, provincial roads, district roads, urban and village roads in the province are well-developed and are distributed rationally in all communes, wards, and towns.13 The project transmission lines will pass through existing inter-commune roads. Commune roads are made of asphalt and some are partly concrete. Access road (length = 900 m; width = 4.5 m) to the project substation will be constructed starting from Province Road No. 965, 1,200m away from the corner with National Highway No 51, in Ong

Trinh village, Tan Phuoc Commune, Tan Thanh District. The renovation of the 72-kilometre Highway No 51 connected Bien Hoa to Vung Tau, slated for completion in the near future, will create an eight-lane link and significantly shorten the travel time between Vung Tau and neighboring provinces, especially Ho Chi Minh City.14

101. Vung Tau Bus Station is located at 52 Nam Ky Khoi Nghia, about 1.5 km northeast of downtown Vung Tau. There are both long distance and local transport services that are available, such as Ho Chi Minh City/SaiGon. 128 km trip is USD$4.00 (2 hours) to SaiGon Hotel (Dong Du between Dong Khoi Street and Ha Bai Trung Street) in District 1. Local bus services include Baria, Bien Hoa, Long Hai, Long Khanh, My Tho and Tay Ninh.

102. Airline: There are airports at Vung Tau and Con Dao Islands although there are no scheduled flights to either at this time. They are used primarily for military and oil drilling purposes.

103. Harbor: Currently, the province has 20 ports with a capacity of about 34 million tons/year. This includes the Thi Vai – Cai Mep complex which has 11 ports, the area of Vung Tau and Con Dao with 8 ports and the Ben Dam fish port. With the port system in operation up to international standards, the area becomes a convenient channel for carriers from around the world for the import and export goods. Accordingly, the output of goods through the ports of the province in 2009 reached about 31 million tons. In the seven months of 2010, output of goods through the port reached 20.63 million tons, estimated the year reached 35.37 million tons.15

104. Water: There is a flying-fish hydrofoil service between Ho Chi Minh City/SaiGon and Vung Tau (USD$10, 1.25 hours) up to 4 times daily (seasonal) from the docks on SaiGon River at Ham Nghi.

105. Railway: The planned Vung Tau-Bien Hoa Railway will also make travel even more convenient for passengers travelling between the key southern economic areas. At a distance of about 500m from the proposed Phu My 2 substation, a designed railway from Ho Chi Minh City to Cai Mep harbor is being planned by the government.

7. LAND USE

106. During the survey process, consultations and agreements had been made with the local authorities about the direction of routes in order to ensure the least impact on houses, land, and people. The direction of routes and location of 220 kV Phu My 2 substation was approved by the People’s Committee of Ba Ria – Vung Tau provinces. The project area mainly passes through paddy fields.

V. ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES

111. This Chapter presents the potential environmental impacts of the project and the recommended mitigating measures to address adverse environmental impacts. The environmental impacts are structured into the (i) pre-construction phase of the project; (ii) construction phase of the substation, connection lines, and access roads, and (iii) operation phase of the project. Mitigating measures are recommended to avoid or minimize adverse environmental impacts.

A. PRE-CONSTRUCTION PHASE IMPACTS AND MITIGATION MEASURES

112. The potential impacts during the design and pre-construction phase of the project are related to the siting and survey of the substation site, road and connection line alignment. There is potential for the substation, access road and connection line alignment to affect houses, irrigation and drainage canals, agricultural land, the Thi Vai River, saltbeds, mangrove areas, ricelands, and village roads. The construction of the towers may also have visual impacts for local residents.

1. LOSS OF PROPERTY AND AGRICULTURAL LAND 113. There are no permanent or temporary buildings on the site of the substation and access road. Thus, the substation and access road will not result in any loss of property or have any impact on human habitation. Overall, the project will require the permanent loss of 61,480 m2 of land while 69,289 m2 of land will be temporarily affected along the ROW (Table 11). These affected lands are primarily used for planting of rice, plantation trees and other crops.

Source: IEE, PECC3

114. The affected vegetation and trees are located along the ROW of the connection lines. These are primarily composed of cajuput and eucalyptus trees. There are 25 houses along the ROW of the connection lines that will be relocated. Another 5 houses near the ROW will not be relocated but will be provided with fireproof materials and lightning arresters. People who live in the proposed ROW are not required to be relocated according to the GOV Decree No. 81/2009/ND-CP dated 12 October 2009. Number of trees and houses that will be affected by the project is shown in Table 12.

115. The SPPMB will design and provide an appropriate land acquisition and compensation plan for the affected area of the substation, ROW of the connection line and access road in accordance with the national requirements. 2. ENCROACHMENT INTO ECOLOGICALLY SIGNIFICANT AREAS 116. The project sites will not encroach on any significant ecological areas. There are no protected areas, primary forest, wetlands, swamp forest, and areas identified as having special ecological significance or identified cultural heritage sites affected by the 220kV/110kV substation and connection lines. There are however, mangroves and estuarine areas in the vicinity of the proposed substation. 117. The SPPMB and consultants of the project selected the sites for the project components through site investigation and coordination with the local government authorities, the Provincial People’s Committee of Tan Thanh. Suggestions and approval of the authorities were secured in selecting the sites. The project also took into consideration the location of historical and cultural relics, natural preservation areas, and populated areas to minimize displacing houses and community structures. The areas close to roads were also selected for easy transport of materials and to avoid significant disturbance of land. 3. IMPACT ON AESTHETICS 118. The impact of the project on aesthetics has not been identified as a significant issue in the local context. There are power plants and industrial facilities in the vicinity and the construction of the new substation will not have a significant effect to the aesthetic of the project area. 4. IMPACT ON DRAINAGE AND FLOODING 119. The substation area and ROW of the connection lines are located in a low-lying area that is vulnerable to inundation. Flooding has been reported in the vicinity. The construction of the substation and tower foundations will require the establishment of a raised platform to ensure adequate protection from flooding. 120. The existing drainage system associated with the surrounding agricultural land is composed of network of irrigation and drainage canals within and around the substation site.

41

The design of the substation will ensure that the existing drainage system will be protected and where necessary additional drainage diversion structures will be included in the works. This is to ensure that the construction and operation of the substation will not have significant impact on the existing drainage system. 121. The construction engineers and designers will also consider the inundation levels in the vicinity in the design the embankments, soil filling, and foundation of the substation and the connection lines. B. POTENTIAL IMPACTS DURING THE CONSTRUCTION PHASE 1. IMPACT ON VEGETATION 122. The construction of the project will have an on agricultural land. In accordance with ADB policy on land acquisition, a resettlement plan has been developed for the project such that the current users of the affected land will be compensated. 123. From the point of view of environmental impact, the loss of rice land is insignificant considering that rice farming and trees below the required vertical clearance may still be allowed when the project is completed. The area of the substation and the ROW of the connection lines were selected to avoid high value plantation trees and forest areas. 2. IMPACT ON GAS TRANSMISSION PIPELINE 124. An underground gas transmission pipeline is located about 200m from the substation. The construction of the connection lines will traverse the said pipeline above ground. It is necessary to ensure safe construction practices particularly in the vicinity of the pipeline to avoid damage and accidents. Extra caution should be made when working near the pipeline area. Coordination with the gas pipeline owners should be also made by SPPMB and the contractor. 3. SOIL EROSION AND FLOODING

125. The access road will affect a river crossing in Thi Vai River and an irrigation canal. The river is located approximately 50m at the northern section of the substation site and is also likely to be the receiving point of potential runoff from the substation. There is also a drainage canal located north of the site. The agricultural land located at the southern section of the site will also likely be impacted to some extent by runoff from the project site and from frequent movement of vehicles to the substation site during the construction phase. Appropriate mitigating measures to prevent soil runoff will be required during the construction of the access road. 126. Timing is also one of the critical factors involved in erosion and sedimentation control in construction sites. Careful scheduling of construction operations can minimize the exposed area during the rainy season. Site clearing, earthworks, and other civil works will be scheduled during the dry season.

42

127. In order to prevent flooding, erosion and runoff of sediments, silt traps or temporary sedimentation facilities should be set-up to trap and settle out runoff from the construction area. Likewise, temporary barriers and trenches should be constructed around the stockpiles of materials to control surface runoff.In combination with the provision of silt traps, the contractor can also implement other best practices to control erosion such as:

(i) scheduling of clearing and grading during the dry season;

(ii) clearing only of areas necessary for construction;

(iii) locating potential sources of pollution away from steep slopes, water bodies or other critical areas;

(iv) cover and stabilize stockpile of topsoil; and

(v) The stockpiles should be covered with tarpaulins, when not in use and at the end of the working day at all times.

128. The effect of sedimentation during project construction is only temporary. Upon completion of the construction stage, exposed surfaces will be concreted while other areas will have trees and plants as part of the architectural landscape.

4. IMPACTS ON WATER QUALITY 129. The construction of the project facilities will have impacts on the water quality of Thi Vai River. Potential sources of water pollution are from the domestic sewage from construction camp, spillage of oil and other lubricants, disposal of construction wastes, and wastewater from washing of construction equipment and vehicles. These wastewaters will potentially pollute the nearby river, including the drainage and irrigation canals. 130. The contractor will be required to implement measures to prevent the discharge of wastewater during the construction of the project from entering directly into the drainage channels and irrigation canals. Measures to mitigate impacts on water quality include:

(i) Provision of adequate on-site sanitation facilities with septic tanks to prevent untreated sewage from being channeled into the drainage canals, irrigation canals, and river;

(ii) Implementation of appropriate solid waste and construction waste collection and disposal system, with provision for waste segregation;

(iii) Designation of areas for equipment services, refueling, and wash down. The maintenance area should be provided with oil and grease traps to prevent oil from being washed into the offsite drainage canals; and

(iv) Preparation of an oil spill emergency response plan.

131. Proper implementation of the above measures will help ensure that the potential water quality impacts during construction will be insignificant.

43

5. IMPACTS ON AIR QUALITY 132. The construction of the project will potentially result to the following impacts on air quality:

(i) Dust arising during excavation and transport of materials (ii) Air pollution due to exhaust gases from construction equipment and transport vehicles.

133. The construction activities will be undertaken in a relatively low population density rural area. The main dust generating activities will be associated with periodic transport of materials to the site. The potential for significant noise, dust nuisance and air pollution on nearby communities from these activities will be minimal and periodic in nature. Good construction practice to minimize these impacts shall be specified in the contract documents. Environmental monitoring will also be strictly implemented to ensure that temporary noise, dust and exhaust gases to nearby communities are at acceptable concentration limit.

6. NOISE 134. The major sources of noise are movement of vehicles transporting construction materials and equipment to the site and the operation of construction equipment such as generators, excavators, and concrete mixers. 135. Noise produced during construction within the substation site will have moderate impact on the community because there are houses, restaurants, and other community structures located in the vicinity of the substation and access road. Noise due to the movement of vehicles along the village access road may potentially result to nuisance. The contractors shall discuss with the concerned communities during public consultation the agreed time on the transport of materials.

7. GENERATION OF CONSTRUCTION WASTES 136. The construction of the substation will generate excavated soils during the site clearing and laying of the foundation for the equipment and control house. Construction activities will also generate debris such as discarded construction materials, cement bags, wood, steel, lubricants, fuels, and vegetation debris. Domestic solid wastes will also be generated from the construction camp. 137. Solid wastes will also be produced when the substation equipment and electrical parts are delivered at the site for installation. This will primarily include packaging materials which could consist of wooden pallets, plastic, foam, and cardboard boxes. 138. The generated wastes during construction, installation of equipment and dismantling of temporary transmission line have the potential to contaminate land and water resources. Air pollution will also be generated when practice of burning wastes is undertaken by workers.

44

139. With proper collection and disposal procedures, the generation of construction wastes will have minimal impact on the environment. Construction materials and stockpiles of soils should be covered to reduce material loss. The stockpiles, lubricants, fuels, and other materials should be located away from steep slopes and water bodies while solid wastes should be disposed of properly in a designated disposal area within the construction site. All domestic solid wastes need to be segregated at source into biodegradable and non-biodegradable for disposal at designated solid waste disposal site.

8. MOVEMENT OF CONSTRUCTION VEHICLES ALONG ACCESS ROADS 140. Access to the site will be along the Provincial Road No. 965 with a proposed access road constructed from the said road to the substation. The hauling of materials to the construction site will result to frequent movement of heavy equipment and construction vehicles along the village access road. Aside from the generation of noise and dust on hauling routes, the movement of construction vehicles will disrupt normal traffic patterns and expose the villagers to risk of injury or accidents. 141. SPPMB will ensure that established practices of posting warning signs and managing traffic to protect the travelling public and its workers will be properly implemented. SPPMB will also ensure that access to adjacent agricultural fields and nearby residences will be ensured throughout the construction period 142. To alleviate such impacts to local settlements, the contractor should closely coordinate with the local communities and engage good practices for traffic management. The contractor should require its drivers to maintain speed of not more than 30 kph (kilometer per hour) when passing through built-up areas. 9. OCCUPATIONAL HEALTH AND SAFETY 143. Construction activities may cause harm and danger to the lives and welfare of workers. The wearing of Personal Protective Equipment (PPE) such as hard hats, safety gloves, ear mufflers, and other materials should be strictly imposed. A construction health and safety plan needs to be prepared and implemented by the contractor. 144. The existing health services near the substation site are located in the community area. The community health service may not be able to accommodate any additional patients from the construction workers. Therefore in the construction phase, the contractor will be required to provide first-aid facilities for the workers and at least one first-aider should be available at the construction camp. 10. COMMUNITY HEALTH AND SAFETY 145. The project construction will result to moderate impacts associated with community health and safety such as construction traffic, transport of materials, fires, emergency spills of materials, and unauthorized entry by the villagers into dangerous working areas. 146. To mitigate these potential impacts, the civil works contractor will be required to develop

45

a Community Health and Safety Plan (CHSP) that incorporates good international practice and recognized standards. The CHSP should include emergency response and preparedness procedures to be developed in close consultation with potentially affected communities and local authorities. The plan should include specific emergency response procedures, communication systems and protocols, interaction with local and regional emergency and health authorities, provision of emergency equipment and facilities such as emergency service vehicles. 147. The CHSP should also include a plan for fencing of the entire construction area and procedures for posting warning signs as required to protect local community members from dangerous work areas. The warning signage should be printed clearly in both English and Viet Nam for better understanding of the villagers. In order to minimize risks from construction traffic, all delivery vehicles will be required to observe the speed limit when passing through built-up areas. C. IMPACTS DURING THE OPERATIONAL PHASE 148. There are no significant adverse environmental impacts during the operational phase of the 500kV substation and connection lines. The expected adverse impacts during the operational phase are confined within the project area. These are generally related to the occupational health and safety issues as well as management of residual wastes. The impacts are reversible, manageable, and can be mitigated with proper engineering and management controls. 1. OCCUPATIONAL HEALTH AND SAFETY 149. The occupational health and safety issues inherent to the operation of transmission line and substation include hazards due to exposure to live power lines and high voltage systems, working in heights and risks of accidents, and potential exposure to electromagnetic fields (EMF). Accidents that may occur include electrocution, fires, and explosion. 150. Exposure to Live Power Lines and High Voltage Systems. Workers may come in contact with live power lines during the maintenance of the facilities and electrocution from direct contact with high-voltage electricity is a hazard directly related to power transmission lines and facilities.20 151. The SPPMB and contractor should be guided by the “Environmental, Health, and Safety Guidelines – Electric Power Transmission and Distribution” (IFC) dated 30 April 2007 when working at the transmission and substation facilities. Some of the prevention and control measures when working with live power lines are:

(i) Restricting access to electrical equipment by workers only trained and certified to work on electrical equipment;

(ii) Adherence to electrical safety standards;

20 International Finance Corporation (IFC), Environmental, Health, and Safety Guidelines – Electric Power Transmission and Distribution. 30 April 2007.

46

(iii) Proper grounding and deactivation of live power distribution lines during maintenance

work or if working in close proximity to the lines;

(iv) Provision of PPE for workers, safety measures, personal safety devices, and other precautions;

(v) Observe guidelines to minimum approach distances for excavations, tools, vehicles, pruning, and other activities when working around power lines and the substation;

(vi) The entrance to all buildings, vaults, rooms, or enclosures containing exposed live parts or exposed conductors should be kept locked unless such entrances are under the observation of a qualified person at all times; and

(vii) Switchboards, panel boards, industrial control panels, meter socket enclosures, and motor control centers that are likely to require examination, adjustment, servicing, or maintenance while energized should be field marked to warn qualified persons of potential electric arc flash hazards.

152. Working in High Elevation. Accidents may happen when working in high elevation. However, a worker safety plan may be implemented to reduce risks that include testing of structural integrity prior to proceeding with the work and the use of fall protection measures. 153. Worker Exposure to Electromagnetic Fields (EMF). Electric utility workers have higher exposure to EMF than the general public because of working in close proximity to electric power lines. The occupational EMF exposure should be minimized through the implementation of an EMF safety program21 that includes:

(i) Identification of potential exposure levels in the work area including surveys of exposure levels and establishment of safety zones;

(ii) Limit access to properly trained workers and those equipped with appropriate PPE when entering safety zones;

(iii) Utilization of personal monitors during work activities; and

(iv) Posting of safety signages and warning signs.

2. COMMUNITY HEALTH AND SAFETY 154. Electrocution. The community may also be exposed to electrocution hazards as a result of direct contact with high voltage electricity or from contact with tools, vehicles, or other devices that come in contact with high-voltage electricity. To prevent these hazards, SPPMB needs to implement the following improvements:

(i) Provision of signs, barriers and gates/posts surrounding transmission towers particularly in built-up areas; and

21 Footnote 20

47

(ii) Grounding of conducting objects such as fences or other metallic structures near power

lines.

155. Exposure to EMF. The transmission frequency commonly used in transmission systems ranges from 50–60Hz which is considered as extremely low frequency22, with impacts becoming low with distance. The electric fields become shielded by trees, buildings, and other materials that conduct electricity. In general, the electric fields are strongest close to the source and diminish with distance. 156. The World Health Organization (WHO) reported that there is still weak evidence about substantive long-term health issues related to low frequency electric fields at levels generally encountered by members of the public. The potential health effects associated with exposure to EMF is not well-established due to lack of empirical data demonstrating adverse health effects. However, the public should be warned about the safety distances from the transmission system and power lines through warning signages. 3. MANAGEMENT OF HAZARDOUS WASTE 157. Chemicals that are commonly handled in the transmission lines and substation are mineral oil in transformers and other electrical components and liquid petroleum fuel. There are also potential hazardous materials and oil spills associated with the operation of equipment and retrofitting/maintenance works. 158. Storage facilities of liquid petroleum fuels for the generator sets and for vehicles and other equipment are potential sources of accidental spills. Oil leak or accidental spills of hazardous materials could give rise to contamination of soil and water. 159. The transformers and equipment should meet international standards and regular maintenance and inspection program should be undertaken to check leaks. The areas around the substation transformers and oil storage areas should be provided with secondary containment with impervious bund capable of holding the oils, fuels, and hazardous wastes in the area. Discharges from these spill bunds with the potential to be contaminated with oil should be directed to the oil-water separators. These are particularly necessary within the substation site and at the maintenance yard. 160. Other chemical and oil spill prevention measures that need to be implemented are emergency spill response procedures, clean-up, and remediation of contaminated soil. 4. EMERGENCY PREPAREDNESS AT SUBSTATION 161. There are several risks that could occur with the operation of the transmission line and substation. Among these are the likelihood of cable being damaged, corrosion of the towers over time which could compromise its structural integrity, potential fire events, explosion of equipment, and being hit by lightning.

22 Footnote 20.

48

162. Lightning arresters are provided along the transmission line and should be provided at strategic locations in the substation. There should also be provision for ensuring security of the cable and substation to avoid vandalism. Regular inspections of the line and the facilities would help identify missing or corroded parts. 163. In case of fire events, explosion, and other related situations, a fire management strategy which may be included in the emergency preparedness and response plan of the project should be developed. Sufficient number of fire protection equipment and fire water tank should be available to address the emergency requirements of the substation. 164. Workers should be trained on emergency preparedness and response procedures and a manual on safety and emergency procedures should be prepared and disseminated to workers like fighting oil fires, e.g. from transformer.

5. MANAGEMENT AND CONTROL OF VEGETATION AT TRANSMISSION LINE 165. One of the regular programs to maintain the integrity of the transmission line is the trimming of tall trees and vegetation along the ROW. This is being done to maintain the necessary conductor clearance of the line. In addition, the presence of vegetation along the ROW provides habitat for birds. With reduced vegetation growth along the ROW, the risk of bird collision on the transmission line will be prevented. 166. The vegetation maintenance activities may cause minor disturbance to local people. This can be mitigated by limiting use to already existing roads or tracks to reach the transmission lines and informing the locals in advance through the village heads on the schedule of the maintenance works. Care should be observed to avoid encroachment into rice or crop land of villagers by workers who will undertake vegetation trimming. 167. SPPMB does not allow the use of herbicides and pesticides to control vegetation growth. Burning to control vegetation along the transmission ROW is also prohibited. 168. To minimize the impacts associated with the removal of vegetation, such activity will only be allowed within the designated width of the ROW and up to the extent of achieving the required clearances. Chain saws and other heavy equipment will not be allowed for the removal of trees. Only manual or hand tools will be used for trimming.

49

V. ANALYSIS OF ALTERNATIVES 169. The following presents the considerations made during the design of the substation and connection lines.

A. NO PROJECT ALTERNATIVE 170. A No Project alternative is not acceptable because the proposed project is an important component of the Master Plan of Power Sector Development of Viet Nam No. VI. Without the project, the load demand in the southern region and in general, the national load will not be met. This would lead to ongoing operating losses for power generation. The present situation will not improve and the reliability and safety of power supply in the southern region will not be attained.

B. SELECTION OF VOLTAGE LEVEL 171. The voltage level of the proposed transmission line was selected based on the duty of the line within the network. Three (2) voltage levels were selected, as follows:

(i) High voltage levels: 220kV, 110kV (ii) Medium voltage level: 22kV

172. During the feasibility, calculations were made on the power distribution and transmission distance. This resulted to the 220kV and 110kV voltage as the most feasible.

C. SELECTION OF SUBSTATION CAPACITY AND QUANTITY OF POWER TRANSFORMER 173. Based on the study of power forecast and the result of power flow, the substation capacity will be 250MVA with three transformers for 220/110kV substation. The economic and technical analysis for the project suggests that the power and electricity requirement can be achieved by installing two transformers for the initial phase of the project.

D. SELECTION OF QUANTITY OF OUTGOING FEEDERS 174. According to the report on the master plan of electrical development in Tan Thanh district and the technical specifications of the existing power grid, the following outgoing feeders will be most efficient and economical for the project:

(i) 220kV will have four outgoing feeders- Phu My 1, Phu My 2, and two in Ba Rai 1; and (ii) 110kV will have eight outgoing feeders- Posco 1, Posco 2, Thi Va1, ThiVai 2, Phu My 1,

Phu My 2, Southern Steel 1 and Southern Steel 2.

50

E. SELECTION OF MAIN CONNECTION DIAGRAM 175. The factors to be considered for an efficient design of electrical connection diagram are security, confidence, simple structure, flexibility in operation, economical, and human safety. Based on the said criteria, the following technical specifications:

(i) 220kV-double bar scheme with two bays each for line feeders and transformers; and (ii) 110kV – double bar scheme with two bays for transformer, one for the coupler and two

bays for each of the line feeders.

F. SELECTION OF FOUNDATION 176. Different types of foundations suitable for the transmission tower were considered. Based on surveys undertaken during the feasibility study of the project, the engineering, geology, relief, and hydrology along the ROW, the main transformer’s foundation will be reinforced concrete, in situ cast with 2x4 stones, and concrete grade M200. This structure minimized fire hazard because it has a void volume that can contain all transformer in case of explosion.

G. SELECTION OF CABLE TRENCHES 177. Based on the economic and technical analysis for the possible design and material of cable trenches, the following were found to be most efficient:

(i) outdoor cable trenches will have inside dimensions of 200mm and 1000mm, reinforced concrete base walls, recast cover plate and slightly inclined;

(ii) crossing road trenches will be reinforced strong enough to withstand vehicle load of transformer conveying; and

(iii) trenches in control room have inside width of 600mm, 1000mm, and 2000 mm, situ cast reinforced concrete, and cover plates with galvanized steel sheets.

H. SELECTION OF ROUTE ALIGNMENT 178. The alignment of the transmission line was selected based on its distance from the 220 kV Phu My 2 thermal powerplant. PECC3 surveyed the existing conditions at the site. The route selection considered avoiding protected areas, forest areas, heritage/cultural sites, houses, trees, and large area of agricultural land.

VI. INFORMATION DISCLOSURE, CONSULTATION, AND PARTICIPATION

179. This Chapter presents the public consultation process that was undertaken for the project, the results of the surveys and consultation meetings, and the concerns raised by the stakeholders. 180. Public consultation meetings were initiated by SPPMB with the affected commune of Tan Phuoc in Tan Thanh district (Ba Ria-Vung Tau province) in March-April 2011. The meetings aim to present the proposed project to the stakeholders and to determine their concerns and issues about the proposed substation project. Issues that were raised by the stakeholders during the consultation meeting included possible impacts of the project on air quality, noise, water quality, and socio-economic activities. The stakeholders asked that appropriate mitigating measures to address any adverse impacts should be planned by the contractor or SPPMB. The following are the suggestions raised by the stakeholders about the management of environmental effects of the project:

(i) Construction activities need to meet environmental regulations and environmental safety;

(ii) Clean up the ground after completion of construction activities; and

(iii) The project has to consider electromagnetic field levels in order to avoid impacts on health of local people.

181. The public consultations resulted to the finalization of the site of the substation and the alignment of the connection lines. Consideration was made on the comments raised by the stakeholders about the alignment, such that, affected houses and productive land were minimized. Other concerns and measures about construction-related issues will be integrated in the terms of reference with the contractor.

52

VII. GRIEVANCE REDRESS MECHANISM 182. A grievance redress mechanism will be established to address concerns of the stakeholders during the project implementation. The grievance redress procedure will comply with the requirements of ADB’s SPS 2009 in addressing people’s concerns and complaints in a timely and effective manner.

A. PRE-CONSTRUCTION PHASE 183. During the pre-construction phase of the project, the most likely grievances that may be encountered involve land acquisition and compensation. A resettlement plan will be prepared to describe in detail the land acquisition and compensation process. The mechanism shall comply with Article 63, 64 of the Decree No. 84/2007/ND-CP dated 25 May 2007 entitled “Amendment on grant of land use right certificate, land acquisition, land use right implementation, compensation, allowances, resettlement sequences and procedures as the State acquires land and in solving grievance of land”. 184. In general, the grievance redress mechanism of the project during the pre-construction phase shall observe the following steps and outlined in Figure 4:

Step 1: The project affected person informs the village head and SPPMB about his/her concerns on the project. A meeting at the commune level will be conducted to discuss the concerns of the complainant. Step 2: If the project affected person is not satisfied with the resolution of the complaint at the commune level, he/she can submit a complaint to the People’s Committee at the district level within 90 days from the date when the chairman of the People’s Committee has decided on land management as stipulated by Article 162 of Decree No. 181/2004/ND-CP. Step 3: If the affected person does not agree with the administrative action or decision of the People’s Committee at the district level, the affected person can elevate the complaint to the People’s Committee at the provincial level within 45 days since the date when the decision on the complaint was issued by the People’s Committee at the district level. Step 4: If the affected person is still not satisfied with the decision of the People’s Committee at provincial level, the complaint is sent to the People’s Court. The decision of the People’s Court becomes the final legal basis for the implementation of the compensation.

B. CONSTRUCTION AND OPERATIONAL PHASES 185. Grievances during construction may also include impacts related to physical construction works on the towers and substation and the site clearing activities. During the operational phase of the project, the complaints that may be anticipated are related to maintenance activities of the connection lines and facilities.

53

Figure 4: Grievance Redress Procedure during the Pre-Construction Phase 186. For complaints received about the construction and maintenance works, the SPPMB will involve the contractor or maintenance personnel. When these are not resolved, any complaints are then facilitated by the General Manager of the SPPMB. 187. The following steps describe the grievance redress procedure during the construction and operational phases of the project (Figure 5).

Step 1: A complainant may send his/her concerns about the construction or operation of the project to SPPMB or the construction contractor and the head of the commune. Immediate action on the complaint is expected from the contractor or the SPPMB on the concern raised by the complainant. The resolution of the complaint should be done within two weeks. Step 2: When the complainant is not satisfied with the action or decision of the SPPMB or the contractor, the complainant can inform the head of the commune about the

54

matter. The commune head/authority through the Commune People’s Committee will then call a meeting of the complainant, SPPMB, and contractor to resolve the complainant. Step 3: When the complainant is not satisfied with the action or decision on the complaint, it the then elevated to the district level for resolution. Step 4: Complaints not resolved at the district level is elevated to the People’s Committee at the provincial level for resolution. Step 5: When the complaint is not resolved at the People’s Committee at the provincial level, the complaint is then elevated to the People’s Court. The decision of the People’s Court becomes the final legal basis for the decision on the complaint.

C. LEGAL GUARANTEE FOR COMPLAINTS AND GRIEVANCES 188. Under the regulations in Viet Nam, project affected persons having complaints or grievances will not be responsible for paying any administrative and legal fees in filing their complaints. Site clearing is not allowed while the resolution of the complaint is still pending. 189. In cases where the affected person is illiterate, he/she can ask assistance from one representative of his household who can then write all the complaints and grievances to be submitted to the district level for resolution. 190. Under the law, all meetings to resolve complaints and grievances should be organized openly and the minutes of meetings should be disclosed and posted at the Commune People’s Committee.

195. Reporting. Regular reporting on the implementation of mitigation measures and on monitoring activities during construction and operation phases of the project is required by ADB and the GOV. Semi-annual monitoring reports are to be submitted to ADB during the construction phase. Monitoring reports to DoNRE are to be submitted quarterly based on the requirements of the approved environmental clearance of the project. Reporting is the responsibility of SPPMB.

C. INSTITUTIONAL ARRANGEMENTS AND RESPONSIBILITIES 196. The SPPMB as the IA of the project will have the overall responsibility for the planning, design, construction, and operation of the project. The SPPMB will also be responsible for the implementation of environmental management, mitigation, and monitoring measures outlined in the EMP. During the design phase, the SPPMB commissioned PECC3 to undertake the feasibility study, IEE, and resettlement plan. 197. Within the current organization of SPPMB, there is one staff who handles matters on environmental management throughout the project phase. The environmental staff is assigned under the Compensation Division of SPPMB. Currently, the environmental monitoring reports are prepared by consultants commissioned by SPPMB. To strengthen the capacity of SPPMB to assess the environmental impacts of its projects and in implementing the EMP and EMoP, training of SPPMB personnel and contractors on best international environmental construction practices, implementation of the EMP and EMoP, and on occupational health and safety will be designed. The capacity building and training activities will be delivered prior to the start of the construction activities and should be followed-up prior to the commissioning of the project. 198. During the construction phase, the SPPMB will require a construction contractor who will be responsible for the detailed design and construction of the project. SPPMB will ensure that the appropriate mitigating measures to address potential environmental impacts are incorporated in the terms of reference with the contractor. The construction contractor will be responsible in implementing the mitigation measures which are recommended during the construction phase. The contractor is also required to submit regular reports on the implementation of the mitigation measures to SPPMB. Specifically, the SPPMB shall manage the project implementation, including environmental management during the construction phase of the project which includes among others, the following:

(i) Assign an environment staff to monitor and manage the implementation of the EMP;

(ii) Ensure that the project implementation is in accordance to the requirements of the GOV and ADB on environmental management and protection;

(iii) Manage and monitoring the activities of construction contractors, particularly in the implementation of the EMP;

(iv) Act by communities on complaints related to the environment; and

(v) Prepare environmental monitoring reports for submission to NPT and ADB. 199. In addition, a Project Implementation Consultant will be commissioned to assist SPPMB in the overall project management.

66

D. ENVIRONMENTAL MANAGEMENT PLAN BUDGET 200. The costs for many of the EMP and EMoP measures are part of engineering, construction, and procurement costs and are not detailed in the EMP budget. EMP costs are mainly included in the EPC package and PIC costs, based on 2 years of construction. (Table 15). 201. The costs for implementing the mitigation measures during the construction phase of the project include the management of soil runoff, dust, and construction wastes, and the training and orientation of workers and community on the health and safety management plan. 202. The SPPMB shall contract a Project Implementation Consultant for one person-month to conduct training on environmental management, occupational health and safety and community health and safety/awareness. 203. During the operational phase, the cost of the EMP are also integrated in the operations cost of the substation and transmission line. Capacity building, field monitoring, and procurement of monitoring devices for the operational phase are also outlined.

IX. CONCLUSION AND RECOMMENDATION 204. The proposed 220kV Phu My 2 substation and connection lines will generate only minor environmental impacts that can be reduced to acceptable levels through the implementation of practical mitigation measures normally associated with internationally accepted good engineering practice. 205. There are no significant sensitive areas that will be affected by the proposed 220kV substation, access road, and connection lines. The sites were selected to avoid environmentally sensitive areas, settlements, forests, and cultural/heritage sites. The vicinity is generally characterized as agricultural land used for planting rice and other crops. 206. The impact of the project on agricultural land is limited and comprises the loss of flat, agricultural land that is being used to plant rice and other crops as well as industrial tree plantations. Compensation for the loss of agricultural production will be paid to the affected households according to the resettlement plan. 207. During the pre-construction phase, the design of the project should take into consideration the findings of the soil investigation, particularly in the design of the foundation for the substation and connection line towers. Other geologic hazards such as liquefaction, soil stability and earthquake and seismic potential of the area should be considered in the design. In addition, the project site is near the estuary and coastal area and salinization may be expected, aside from potential corrosion effects of industrial plants in the vicinity. Salinization and air pollution may cause damage to the steel towers and other facilities of the substation and connection lines. In order to protect the high voltage insulator lines from air pollution (particulate matter, salt content, etc.) in the area, a creepage distance of 31 millimeter per kilovolt (mm/kV) is to be applied in the design. These insulator lines are designed according to the Electrical Equipment Standard 11 TCN-19-2006. 208. The impacts of the project during the construction phase are limited to the surrounding area and can be readily mitigated. The adverse impacts likely to occur during the construction phase are considered temporary in nature and could be mitigated through proper design and integration of the proposed mitigation measures. The impacts during the construction of the project are primarily due to the clearing of the existing vegetation, earth filling at the substation site to prevent inundation, and construction safety. These are briefly described in the following paragraphs:

(i) The substation will be located in an area that is flood-prone, hence, will require earth-filling to raise the elevation of the site. The design of the drainage plan will take into consideration the increased runoff and soil erosion from the site. Engineering controls for erosion protection measures such as silt traps and sedimentation ponds will be integrated in the management plan.

(ii) There will be potential water pollution, sanitation, and health hazards due to presence of workers camp. Adequate water supply and toilet facilities will be established at the existing construction camp.

68

(iii) A construction health and safety plan shall be required from the contractor, including provision of first-aid facilities to provide measures and procedures in addressing occupational health and safety at the construction site.

(iv) The movement of construction vehicles along the access roads would contribute to the

increase in ground level concentration of total suspended particulates (dust), noise, and could also result to accidents and hazards to communities living along the access roads. Measures such as limiting of construction hours and deliveries to the site at night and imposition of speed limit to vehicles will be implemented.

(v) Impacts related to community health and safety such as construction traffic, transport of

materials, fires, emergency spills of materials, and unauthorized entry by the villagers into dangerous working areas will be mitigated through the development of a Community Health and Safety Plan (CHSP) that incorporates good international practice and recognized standards that includes fencing of construction area, posting of warning signs in Vietnamese language, emergency response and preparedness procedures, communication systems and protocols, interaction with local and regional emergency and health authorities, provision of emergency equipment and facilities such as fire truck, emergency service vehicles, and fire drills will be established.

209. The impacts during the operational phase include the concern about EMFs and management of hazardous wastes at the substation and connection lines. The community and workers will be protected against electrocution hazards as a result of contact with high voltage electricity through the provision of signs, barriers, and gates/posts surrounding the towers, particularly in built-up areas. 210. An EMP has been prepared and will be implemented during all phases of project implementation. The EMP identifies the potential environmental impacts from the project. It also includes the institutional arrangements for implementing the EMP to ensure its sustainability and effectiveness. 211. The project will provide positive impacts to the community because the substation and connection lines meet the power demand of Hung Yen, other neighboring provinces in the northern region. 212. Based on the analysis conducted in this assessment it is concluded that overall the project will result in significant positive socio-economic benefits, and those potential negative environmental impacts that have been identified are small-scale and localized, and can be minimized adequately through good design and the appropriate application of mitigation measures. It is therefore recommended that the project be supported by ADB, subject to the implementation of the commitments contained in the EMP and allocation of appropriate technical, financial and human resources by implementing agencies to ensure these commitments are effectively and expediently implemented. This IEE is sufficient and there is no need for further environmental assessment.

√

The sites are not designated as special areas for biodiversity protection.

B. POTENTIAL ENVIRONMENTAL IMPACTS WILL THE PROJECT CAUSE…

� encroachment on historical/cultural areas, disfiguration of landscape and increased waste generation?

√

Compensation will be made by SPPMB on the affected temple/cemetery.

� encroachment on precious ecosystem (e.g. sensitive or protected areas)?

√

The project will not encroach on sensitive or protected areas.

� alteration of surface water hydrology of waterways crossed by roads and resulting in increased sediment in streams affected by increased soil erosion at the construction site?

√

The access road will pass through Thi Vai River and irrigation canal. Mitigating measures to avoid runoff of sediments into these water bodies will be designed.

� damage to sensitive coastal/marine habitats by construction of submarine cables?

√

There are no submarine cables to be installed by the project.

� deterioration of surface water quality due to silt runoff, sanitary wastes from worker-based camps and chemicals used in construction?

√

This will be avoided or minimized through proper implementation of mitigating measures.

� increased local air pollution due to rock crushing, cutting and filling?

√

This will be avoided or minimized through proper implementation of mitigating measures.

� risks and vulnerabilities related to occupational health and safety due to physical, chemical, biological, and radiological hazards during project construction and operation?

√

To minimize potential risks an Occupational Health and Safety Plan (OHSP) will be developed and Implemented.

� chemical pollution resulting from chemical clearing of vegetation for construction site?

√

No herbicides will be used during the construction phase.

� noise and vibration due to blasting and other civil works?

√

Minor noise impacts will occur during movement of construction vehicles along access road.

� dislocation or involuntary resettlement of people?

√

The substation, connection lines, and access roads were designed to avoid houses and buildings and the dislocation of households. There will be about 10 households to be relocated.

� disproportionate impacts on the poor, women and children, Indigenous Peoples or other vulnerable groups?

√

Not likely. Social Impact Assessment process is being undertaken separately.

75

Screening Questions Yes No Remarks � social conflicts relating to inconveniences in living

conditions where construction interferes with pre-existing roads?

√

Road closures are not anticipated to be necessary. Construction activities and the transport of materials including aggregate may cause some damage to roads and other local infrastructure. Any damaged infrastructure will be repaired to at least the same standard and condition on completion of the Project. A survey will be done at the commencement of the Project to determine the initial condition of such infrastructure.

� hazardous driving conditions where construction interferes with pre-existing roads?

√

Existing access roads are suitable for construction activities, and no hazardous driving conditions are anticipated.

� creation of temporary breeding habitats for vectors of disease such as mosquitoes and rodents?

√

International good construction practices will be implemented. Areas of ground disturbance will be restored to prevent creation of ponds and mosquito breeding areas.

� dislocation and compulsory resettlement of people living in right-of-way of the power transmission lines?

√

The project location was designed to avoid houses.

� environmental disturbances associated with the maintenance of lines (e.g. routine control of vegetative height under the lines)?

√

It is anticipated that the maintenance of trees and vegetation within the ROW will create minor disturbance. Majority of existing vegetation are riceland.

� facilitation of access to protected areas in case corridors traverse protected areas?

√

The substation, connection lines, and access roads were aligned to avoid protected areas.

� disturbances (e.g. noise and chemical pollutants) if herbicides are used to control vegetative height?

√

The use of herbicides will not be allowed.

� large population influx during project construction and operation that cause increased burden on social infrastructure and services (such as water supply and sanitation systems)?

√

Temporary worker camps will be small, and will be required to be provided with appropriate sanitation facilities, including water supply, and washing facilities, temporary toilets, and waste containers. The worker camp sanitation facilities should be developed in consultation with relevant local authorities and should have all required local, province and national approvals.

� social conflicts if workers from other regions or countries are hired?

√

Hiring of workers from outside the locality may cause concerns among local communities. To mitigate against this, it will be necessary to communicate about employment opportunities with the commune and provide employment priority to qualified workers in the commune.

76

Screening Questions Yes No Remarks � poor sanitation and solid waste disposal in

construction camps and work sites, and possible transmission of communicable diseases from workers to local populations?

√

Contractors should be required to provide adequate sanitation facilities in the workers’ camps.

� risks to community safety associated with maintenance of lines and related facilities?

√

Risk from line maintenance is very low. A Community Health and Safety Plan (CHSP) will be developed so as to minimize any potential threats.

� community health hazards due to electromagnetic fields, land subsidence, lowered groundwater table, and salinization?

√

The connection lines have been carefully routed and substations carefully sited to ensure that final alignment avoids to the maximum extent possible sensitive locations such as houses and schools. The project design follows WHO and IRPA guidelines. In addition, during operation monitoring will be undertaken to ensure EMFs are within national and international standards/guidelines. Land subsidence and lowered groundwater table is not anticipated.

Salinization is anticipated because the substation is located near an estuarine area.

� risks to community health and safety due to the transport, storage, and use and/or disposal of materials such as explosives, fuel and other chemicals during construction and operation?

√

Good international practices will be adopted regarding the storage and handling of fuel, oil and hazardous materials, and occupational and community health and safety plans will be developed and implemented.

� community safety risks due to both accidental and natural hazards, especially where the structural elements or components of the project (e.g., high voltage wires, and transmission towers and lines ) are accessible to members of the affected community or where their failure could result in injury to the community throughout project construction, operation and decommissioning?

√

Community safety risks with power lines and substations include unauthorized access. Safety and warning signs will be installed. The towers will be fitted with anti-climbing devices and substations will have a security fence and full-time security personnel on site.

Climate Change and Disaster Risk Questions The following questions are not for environmental categorization. They are included in this checklist to help identify potential climate and disaster risks.

Yes No Remarks

77

� Is the Project area subject to hazards such as earthquakes, floods, landslides, tropical cyclone winds, storm surges, tsunami or volcanic eruptions and climate changes (see Appendix I)?

√

The substation site has been reported to experience inundation during heavy rainfall events. Soil filling and embankments will be designed to protect the substation from flood. The site is located in a relatively flat land. The potential for landslides in unlikely but erosion of sediments from construction activities will be controlled through the adoption of good international construction practice erosion control measures.

� Could changes in precipitation, temperature, salinity, or extreme events over the Project lifespan affect its sustainability or cost?

√

Not likely.

� Are there any demographic or socio-economic aspects of the Project area that are already vulnerable (e.g. high incidence of marginalized populations, rural-urban migrants, illegal settlements, ethnic minorities, women or children)?

√

Not likely.

� Could the Project potentially increase the climate or disaster vulnerability of the surrounding area (e.g., increasing traffic or housing in areas that will be more prone to flooding, by encouraging settlement in earthquake zones)?

√

No.
