I. INTRODUCTION
At present, power source supplying Can Gio district is Nha Be 220kV Substation (2x250 MVA) and one diesel generator with the capacity of 400 kW supplies power to Thanh An commune locating on one island (called Thanh An island commune).
The existing Nha Be – An Nghia – Can Gio 110kV single-circuit transmission line (TL) directly supplies power to An Nghia and Can Gio 110kV substations. In the future, this TL will supply power to Aquaculture Center 110kV SS (newly constructed) (1x40MVA) and ensure to supply power to An Nghia and Can Gio 110kV substations that will be enhanced their capacity to 2x16MVA/ SS.
Now, Nha Be - An Nghia - Can Gio 110kV TL hasn’t been closed loop, thus it does not ensure to supply stably and reliably Can Gio district with power. In the other hand, the existing TL’s some sections are still used AC120 conductor with the load capacity of 70MVA, thus it does not ensure power transmission for 110kV substations which will be enhanced capacity and constructed newly in the region in the future (104MVA).
“Stabilization and reliability enhancement of power source for supplying Can Gio district -HCMC” subproject is one of the subprojects, which will be implemented in stage I of Vietnam Distribution Efficiency Project (DEP) of Vietnam Electricity (EVN) loaned by the WB, and constructed in the area of Can Gio district - HCMC.
Activities of the subproject include:
i) Upgrading (to keep tact the TL direction and its ROW, only change in tower foundation location, conductor pulling and scatter) the existing single-circuit 110kV TL to the double circuit TL for the TL section from tower No. 32 (T32) to tower No.53 (T53) with 4.06 km in length (hereafter called Section 1);
(ii) Taking down the existing single-circuit 110kV TL for the TL section from tower No.32 (T32) to tower No.53 (T53);
(iii) Newly constructing a double-circuit 110kV TL section from tower No.53 (T53) of the existing single-circuit 110kV TL to An Nghia SS with 9.915 km in length (hereafter called Section 2);
(iv) Taking down the existing single-circuit Nha Be – An Nghia 110kV TL section from the existing tower no.53 (T53) to the existing tower no.108 (T108) with 9.7km in length.
These activities can cause negative impacts on environment and local communities in the stages of pre-construction, construction and operation of the subproject.
To ensure that potential negative impacts are determined and mitigated during subproject implementation process and conformed to the WB’s environmental assessment policy (OP/BP 4.01), an environmental management plan (EMP) of the subproject has been prepared in accordance with the guidance of the DEP’s Environmental Management Frame (EMF). The EMP includes contents as description of the subproject, policy framework, applied national technical regulations on environment, potential negative impacts, proposed impacts mitigation measures which will be implemented in the stages of pre-construction, construction and operation, and implementation organization and arrangement.
According to new Vietnamese regulations, the subproject must establish a report on environmental impact assessment (EIA). Its EIA is being established to submit to the Department of Natural Resources and Environment of HCMC for approval instead of the previously approved Environmental Protection Commitment (This commitment was established by the PO and approved by Can Gio DPC at Letter No. 409/XN-UBND-TNMT dated October 19th, 2007).

| | | |impacts on vegetation cover of Can Gio Protective Forest (the 133m- length TL section crossing over the protective |
| | | |forest has one tower foundation to be newly constructed on the old An Nghia 110kV SS ground. |
| | | |It should design the height of conductor higher than the highest tree (not cut down tree under the ROW). |
| | | |During the process of the TL construction and conductor scatter and pulling through the protective forest, it should|
| | | |not cut down tree under the ROW. Erecting scaffolding to support conductor in accordance with Norms. The height of |
| | | |the scaffolding need be conformed to stipulation for every project it need overcome. The scaffolding will be firmly |
| | | |connected together to support many conductors at the same time. It will be ensured to resist wind pressure, vertical|
| | | |load and the other expected loads. |
| | | |Therefore, the impacts on Can Gio Protective forest caused by the subproject are assessed as small. |
|- Estuaries | |No | |
|- Buffer zone of protected areas | |No | |
|- Rivers and reservoirs |Yes | |- Don’t design tower in rivers, reservoirs. |
| | | |- Section 1: The TL crosses over Rach La canal with the width of 155m once, and Rach canal with the width of 50m |
| | | |once. Now, boats still travel in these canal sections. |
| | | |- Section 2: The TL crosses over Rach La canal with the width of 86 m once and Ong Nghia river with the width of 105|
| | | |m once. Now, boats still travel in these canal sections. |
| | | |The subproject will not much affect the traveling activities of boats. The impacts are only temporary in the |
| | | |construction time (about one day). |
|- Canals, ditches and irrigation system |Yes | |- There is no irrigation system in the subproject area. |
| | | |- The subproject doesn’t design tower in rivers, reservoirs |
| | | |- Canal/ditch system in the subproject area is relatively much, thus the TL crosses over some small canals/ ditches |
| | | |(their width is from several meters to several-ten meters). However, the TL won’t impact on this ditch/canal system,|
| | | |because it is in the air, and its tower foundations are not adjacent to canals, ditches. |
|- Agricultural land |Yes | |- Section 1: acquiring 3,259m2 land for constructing tower foundation (20 tower foundations), in which there area |
| | | |414 m2 paddy land, 585m2 other annual tree land (nipa), 2,260m2 aquaculture land (shrimp farms). |
| | | |- Section 2: acquiring 188 m2 paddy land and 327m2 other annual tree land (nipa) for tower foundation construction. |
|2. Potential environmental impacts | | | |
|Will the subproject cause: | | | |
|2.1. Pre-construction stage | | | |
|Permanent land acquisition |Yes | |Total permanently acquired land area for tower foundation construction is as follows: |
| | | |- Section 1: Total permanently acquired land area for tower foundation construction is 3,259 m2 (20 tower |
| | | |foundations). In which, there are 414 m2 rice land; 585m2 annual tree land (nipa); 2,260m2 aquaculture land (shrimp |
| | | |farms). The area of the smallest tower foundation is 124.32m2. The area of the largest tower foundation is 174.24m2.|
| | | | |
| | | |- Section 2: Total permanently acquired land area for tower foundation construction is 6,904m2 (52 tower |
| | | |foundations), In which, there are 188m2 rice land; 327m2 annual tree land (nipa); 6,389m2 traffic land (green belt |
| | | |between Rung Sac and Song Hanh roads). |
|Temporary land acquisition |Yes | |- Section 1: Total land area under the ROW is 64,960m2. Besides, the subproject will also acquire temporarily land |
| | | |without the ROW with the area of 1,037m2 for constructing the worker camps, stockpiles,…In which, there are 247.3m2 |
| | | |closed stockpile; 515.6m2 opened stockpile; and 274.1m2 construction material storage yard. |
| | | |- Section 2: Total land area under the ROW is 158,640m2. Besides, the subproject will also acquire temporarily land |
| | | |without the ROW with the area of 1,064.73m2 for constructing the worker camps, stockpiles,…In which, there are |
| | | |163.18m2 closed stockpile; 235.60m2 opened stockpile ; 665.95m2 construction material storage yard. |
| | | |The subproject construction will be implemented in 9 months (from December 2012- August 2013) therefore the impacts |
| | | |caused by temporary land acquisition are insignificant. The subproject will return the ground after completing |
| | | |construction, acceptance and hand-over. |
|Resettlement of households? If yes, how many households? | |No |There are no resettled households |
| | | |Section 1: None of HHs has house/structure under the ROW. |
| | | |Section 2: From G1 - G3, there is 01 house, 03 auxiliary structures (bathroom, toilet and animal husbandry stall) of|
| | | |2 HHs under the ROW, they are not compensated, but are allowed to keep under the ROW after their wall and roofing |
| | | |are upgraded and grounded. |
| | | |The TL section from G3 to the ending point, which runs in the green belt between Rung Sac and Song Hanh roads, there|
| | | |are 01 house, 10 other structures under the ROW. They were inventoried and compensated by the Project Owner of Rung |
| | | |Sac road in 2004 and 2005 |
| | | |For HHs whose houses/structures are under the ROW but not dislocated out of the ROW, the Project Owner will |
| | | |implement treatment measures as upgrading, grounding (to prevent from electromagnetic field) these |
| | | |houses/structures. |
|Would the resettlement site is environmentally and/or culturally | |No |There is no resettlement site |
|sensitive | | | |
|In the past, there was any accident incurred due to Unexplored ordnance | |No |No |
|after the war (due to landmines or explosive materials remaining from | | | |
|the war)? | | | |
|2.2 Construction stage | | | |
|Encroachment on historical/cultural areas | |No | |
|Encroachment on critical ecosystem (e.g. sensitive or protected areas, | |No |- The subproject won’t construct tower foundation in forest land. |
|national park, nature reserve etc....) | | |- The subproject won’t use tower made of wood.(wood tower) |
|Disfiguration of landscape and increase in waste generation |Yes | | * It will cause the disfiguration landscape in permanently acquired land area, particularly as follows: |
| | | |- Section 1: The area of permanently acquired land for tower foundation construction of the upgraded TL is 3,259 m2 |
| | | |(this area is for 20 tower foundations). In which, there are 414 m2 paddy land; 585m2 other annual tree land (nipa);|
| | | |2,260m2 aquaculture land. The area of the smallest tower foundation is 124.32m2. The area of the largest tower |
| | | |foundation is 174.24m2. |
| | | |- Section 2: Total area of acquired land for tower foundation construction is 6.904m2 (this area is for 52 tower |
| | | |foundations), including 188m2 paddy land; 327m2 other annual tree land (nipa) land; 6,389m2 traffic land (green belt|
| | | |between the roads of Rung Sac and Song Hanh). |
| | | |- Wastes will include redundant soil and rock in construction process; rubbishes from workers’ activities; wastes |
| | | |generated by taking down and salvaging the existing TL unless they are collected and treated rationally. |
|Removal of vegetation cover or cut down of trees resulted from clearance|Yes | |* Number of trees affected by the subproject is as follows: |
|along the ROW? | | |- Section 1 |
| | | |+ The area of the affected paddy field is 960 m2; |
| | | |- Section 2: |
| | | |+ The area of the affected paddy field is 1,744m2; |
| | | |+ Number of nipa which will be cut down is 355 trees; |
|Change of surface water quality or water flows |Yes | | - In the subproject area, the turbidity of surface water sources will be increased due to the impacts of tower |
| | | |foundation excavation activities and water pumped from foundation pit (if any) will run into the rivers/canals in |
| | | |the subproject area as Tra canal, La canal and Ong Nghia river. |
|- Increase in water turbidity due to run- off and erosion |Yes | |Tower foundation excavation and filling process will cause soil/rock to be loosen (especially tower foundations are |
| | | |located in complex locations) Therefore it will cause an increase in surface water source’s turbidity in rainy |
| | | |season. This impact is only temporarily in construction stage. Specifically, the TL crosses over the following large|
| | | |rivers/canals: |
| | | |- Section 1: Tra canal with the width of 155m; Rach canal with the width of 50m; |
| | | |- Section 2: Rach La canal with the width of 86m and Ong Nghia river with the width of 105m. |
| | | |However, topography of the subproject area is relatively flat, and height difference of two river bank sides (slope |
| | | |of two river banks) is small, therefore soil erosion will be low. |
|- Waste water from camping sites is directly discharged to the surface |Yes | |- Number of construction workers will be different at every construction time. Thus, the volume of waste water |
|water resources or not? | | |generated at each construction time will be different. |
| | | |- The subproject surrounding area, the road and waterway system is relatively high developed, local people are |
| | | |living here thus, won’t build camps for worker, but hire local people’s house for worker to stay. For this reason, |
| | | |they won’t stay together in a place but stay dispersedly along the TL. |
| | | |- Section 1: Total number of workers participating in the subproject construction will be 167 people, thus total |
| | | |volume of wastewater generated will be 13.3m3/day; this sewage won’t concentrate but distribute dispersedly at the |
| | | |residents’ houses hired for workers. |
| | | |- Section 2: Total number of construction workers will be 130 people, including 02 independent teams, each team has |
| | | |65 people (with 60 direct people, 03 indirect people and 02 managers). Waste water volume generated in one day will |
| | | |be about 10.4m3/day at the residents’ houses hired for workers. |
| | | |Characteristic of the transmission line is to carry out construction for every tower foundation. Construction |
| | | |workers will be divided into small groups, thus waste water will not gather in a place but distribute dispersedly in|
| | | |every tower foundation. At each tower foundation location, there are about 15-20 people, construction time of each |
| | | |tower foundation is about 11 days/foundation. Hence, waste water volume generated at each tower foundation location |
| | | |is about 1.2 – 1.6 m3 /day.foundation. This volume of waste water is small. |
|- Construction waste water is directly discharged to the surface water |Yes | |Construction waste water is mainly generated from underground water of foundation pits, water for concrete |
|or not? | | |maintenance. |
|Increase in the dust level? |Yes | |- Dust is generated by ground leveling of the auxiliary area (stockpiles, workers camps…) |
| | | |- Dust is generated by tower foundation excavation and filling. |
| | | |- Dust is generated by materials and equipment transporting vehicles |
|Increase in noise and/or vibration? |Yes | |- Dust is generated by ground leveling of the auxiliary area (stockpiles, workers camps) |
| | | |- Dust is generated by tower foundation excavation and filling. |
| | | |- Dust is generated by materials and equipment transporting vehicles. |
| | | |- Number of machines participating in the subproject construction is as follows: |
| | | |+ Section 1: Total time of tower foundation construction is short. Number of machines and equipment used in |
| | | |construction is not many, including 01 concrete mixer with 150 – 250 liters; 02 needle vibrators; 01 plate vibrator |
| | | |+ Section 2: Total time of the subproject construction will be 9 months. Machines and equipment used in construction|
| | | |include 12 concrete mixers; 31 trucks transporting equipment and materials; 03 cranes; 05 bulldozers, excavator; 20 |
| | | |needle vibrators; 12 plate vibrators; 12 welding machines; 12 steel benders; 4 diesel generators; 18 water pumps; 12|
| | | |hydraulic wire compressors. These machines and equipment won’t be operated at the same time, but dispersedly at each|
| | | |stage, work item, construction area. Therefore, noise won’t be concentrative but dispersedly on the whole TL. |
| | | |The process of tower foundation excavation and filling, and ground leveling will be performed mostly by manual |
| | | |method. The construction activities will be carried out in the daytime, and the transportation of materials and |
| | | |equipment to the subproject site will be performed by manual and mechanical method. Therefore, the impacts caused by|
| | | |noise on people in the subproject area are very small. |
|Is there any risk of disease dissemination from construction workers to |Yes | |Through information collection, the subproject area has had mumps. According to the collected information on |
|the local people (and vice versa)? | | |Vietbao website, up to November 24th, 2011, in the territory of Can Gio district, there had been 160 people had |
| | | |mumps (including 151 pupils). Also in the same period, in the subproject area in Binh Khanh commune there was 01 |
| | | |case of mump catch. Therefore, concentration of workers in the subproject area will increase risks of spreading |
| | | |disease to workers and community. |
|Is there any potential for conflict between construction workers and |Yes | |Concentration of workers will cause disturbance daily life of local people. Construction workers are managed by the |
|local peoples (and vice versa)? | | |contractor and registered temporary residence registration to the local authority. However, conflicts between |
| | | |construction workers and local people may be happened due to objective reasons. |
|Are explosive and hazardous chemicals used within the subproject? | |No | |
|Will the subproject construction cause disturbance to the transportation|Yes | |- Materials and equipment transportation for the subproject construction will affect traffic activities in the area:|
|in the subproject site? | | | |
| | | |+ The subproject construction will be implemented in a short period. According to the proposed construction |
| | | |schedule, the subproject will be implemented within 6 months for the TL section 1; and 9 months for the TL section 2|
| | | |from the subproject preparation to the completion and acceptance. |
| | | |+ Section 1: Minor impact: The subproject crosses over some roads. Especially, it crosses over the large earth road |
| | | |once, Tran Quang Quon road once, and Ha Quang Voc road once. The surface width of these roads is 5m with sand |
| | | |foundation, gravel pavement, and low vehicle density. Number of vehicles participating in material transportation |
| | | |activities of the subproject won’t be many, therefore this impact is assessed insignificantly. |
| | | |+ Section 2: Medium impact: The subproject will cross over the inter-village and inter-commune roads 36 times. Of |
| | | |which, it crosses over the asphalted roads with the width of 5–11m 09 times, the earth roads with the width of 3-10m|
| | | |27 times. On the earth roads, the density of vehicles isn’t high. Otherwise, on the asphalted/concreted |
| | | |inter-village/inter-commune roads with the quality of good road surface, the density of vehicles and people |
| | | |participating in transport activity is high such as the road accessing to Binh Khanh high school, Binh Phuoc high |
| | | |school. |
| | | |Total number of material transportation vehicles for the subproject construction is 37 pieces including 05 trucks |
| | | |for transporting steel towers; 8 trucks; 12 dumper trucks, 06 water + fuel tank trucks; 06 worker buses. |
| | | |Thus, vehicles serving material transportation for the subproject construction will cause disturbance the |
| | | |transportation in the area, however this impact will occur only in a short period (in the construction process) and |
| | | |only in the time of one tower foundation construction and the time of conductor pulling and scatter in one tower |
| | | |span. |
| | | |- Conductors pulling and scatter activity: In the process of conductor pulling and scatter though roads, the |
| | | |subproject will affect traveling activity of local people and vehicles. However, this process will be performed only|
| | | |in a short period, and conductor pulling and scatter is implemented in the air. Therefore, it won’t affect much |
| | | |transportation activity. |
|Will the subproject construction damage to the existing local roads? |Yes | |According to the actual survey, topography in the subproject area is flat, low. Roads in the area are mainly earth |
| | | |ones, of which few roads the TL crosses over are asphalted ones/concreted ones. Almost roads have low vehicle and |
| | | |people density. They easily become muddy in rainy season. This causes difficulty in traveling of local people. On |
| | | |the other hand, the participation of vehicles for the subproject construction will increase degradation, damage of |
| | | |road’s pavement. |
|Will soil excavation during the subproject construction cause soil |Yes | |- It can cause soil erosion due to tower foundation excavation: The impact will be minor because the process of |
|erosion? | | |tower foundation excavation will be mainly by manual method with tools such as hack, scoop, crowbar, etc and |
| | | |combined with mechanical method. |
| | | |- Section 1: Tower foundations of the subproject will be mainly located in shrimp farms, thus before constructing |
| | | |embankment that will prevent from water to pump water for tower foundation construction, carrying out careful |
| | | |excavation to prevent from landslide, erosion; and checking the depth of foundation pits as designed. Excavated soil|
| | | |volume will be 14,450.53m3, filled soil volume will be 9,763.94m3. These tower foundation locations is located in |
| | | |the hollow places therefore it won’t cause erosion. |
| | | |+ For foundations in the embankments of shrimp farms, excavation can cause erosion and landslide |
| | | |+ The subproject area’s topography is mainly low and hollow, and some foundations are in shrimp farms, thus erosion |
| | | |by excavation is insignificant, |
| | | |- Section 2: |
| | | |+ Volume of excavated soil is 29,550.94m3; volume of filled soil is 32,748.84m3. |
| | | |+ The subproject area’s topography is mainly low and hollow, and some foundations are in the green belt of Rung Sac |
| | | |road, therefore erosion caused by excavation is very small. |
|Will the subproject need to open new access roads? | |No | |
| Will the subproject need to open temporary roads for construction |Yes | |- Section 1: The subproject will construct temporary roads (not cross through residential areas, schools, hospitals)|
| | | |to transport equipment as well as materials and prefabricated elements to each location. |
| | | |Some tower foundations in this section are mainly located in shrimp farms, so access road will use its embankments. |
| | | |- Section 2: Do not construct temporary roads. |
|Will the subproject cause fragmentation of habitat of flora and fauna? |Yes | |The impact is insignificant |
| | | |- Section 1: |
| | | |+ The TL’s length through shrimp farms is 3,575m; |
| | | |+ The TL’s length through the nipa, paddy area is 150m. |
| | | |+ The TL’s length through river, stream is 335m |
| | | |Tower foundations located in shrimp farms will be constructed after harvesting. It should is embanked and |
| | | |constructed quickly and completely for every foundation. |
| | | |- Section 2: The affected trees within the ROW are as follows: |
| | | |+ The affected paddy area is 1,744m2; |
| | | |+ Number of Nipas which will be cut down is 355 trees; (in the scope of tower foundations) |
| | | |- Cutting down trees within the ROW will cause some small species such as bird, insect, etc to lose their habitat. |
| | | |The activities of the subproject construction and the appearance of workers will cause disturbances to the life of |
| | | |animal species (some animal species will leave their habitat) in the area. |
|Will the subproject cause impact on air quality? |Yes | |- Increasing dust, exhausted gases, etc … due to activities of vehicles and equipment in the construction process |
| | | |(due to soil excavation and filling, transporting materials). |
| | | |- Dust will be generated by the activities of tower foundations and auxiliary works excavation, filling and |
| | | |leveling. |
| | | |- Dust, gases (SO2, NO2, CO, etc) will be emitted from vehicles that will be used to transport materials and |
| | | |equipment for construction; and from machines that are used in construction. In the materials transportation process|
| | | |on earth road will increase dust in the air. |
| | | |- Section 1: equipment and machines directly participated in the subproject construction will include 01 concrete |
| | | |mixer with 150 – 250 liters; 02 needle vibrators; 01 platform vibrator; |
| | | |- Section 2: equipment and machines directly participated in the subproject construction will not be concentrated. |
| | | |Therefore, gas emission will have a low concentrated level, and construction period of tower foundation will be |
| | | |short about 11 days/foundation. These impacts will be only temporary in construction phase. |
|Will the subproject cause risk to safety and health of workers and |Yes | |- In the subproject construction process, accidents can happen for workers and local people if safety regulations |
|communities in construction stage? | | |aren’t fully obeyed in construction. The accidents can happen such as traffic accidents, accidents due to touch with|
| | | |equipment and machines, and fall from high working places, etc. |
| | | |- Accidents can happen inside or outside the subproject site (on the road used to transport materials and equipment,|
| | | |etc). |
|2.3. Operation stage | | | |
|Will the subproject cause risk to safety and human health (electric and |Yes | |The subproject can cause accidents that will affect people in the process of construction and operation. |
|magnetic fields, electric shock etc.)? | | |- Electric shocks and accidents will happen if safety measures aren’t fully obeyed. |
| | | |- Fire, explosion incidents can happen due to short circuit, lightning or breaking conductors that cause danger to |
| | | |workers, people staying near the accident positions, etc. |
| | | |- The distance from any components of houses/structures to the nearest conductor when it is in maximum sag status is|
| | | |not less than 4m. This distance can be encroached in operation process and cause accidents for people who encroach. |

- Instructing the Contractor(s) to take actions to reduce impacts and follow the required EMP procedures in case of non-compliance / discrepancies identified;
- Instructing the Contractor(s) to stop activities which generate adverse impacts, and/or when the Contractor(s) fails to implement the EMP requirements / remedial actions.
- For contracts that Site Environmental Management Plan (SEMP) are required, the CSC shall provide the final review and recommend clearance of all Site Environmental plans which may affect the environment. These include, but are not limited to: dredging areas, borrow pits and disposal sites, worker’s camp plans. The CSC will review and approve the SEMP presented by the Contractors. Where these plans are found not to comply with the EMP, EIA or RAP, the CSC shall work with the HCMC Power Project Management Board and Contractor to establish a suitable solution.
- Addressing Complaints: Complaints will be received by the Contractor’s Site Office from local residents with regard to environmental infractions such as noise, dust, traffic safety, etc. The Contractor’s Chief Engineer or his deputy, and the CSC shall be responsible for processing, addressing or reaching solutions for complaints brought to them. The CSC shall be provided with a copy of these complaints and shall confirm that they are properly addressed by the Contractors in the same manner as incidents identified during site inspections.
- Certification for Monthly Payments: The CSC shall confirm the monthly payments for environmentally related activities implemented by the Contractor.
- Reporting: the CSC shall prepare the following written reports:
o Bi-weekly report of non-compliance issues
o Summary monthly report covering key issues and findings from reviewing and supervision activities
