Chapter I

INTRODUCTION AND BACKGROUND

1.1. INTRODUCTION ABOUT PROJECTSong May 500 kV Project (from hereby it will be called as the Project) consists of

three subprojects, they are:- Song May- Tan Dinh 500 kV transmission line;- Phu My- Song May 500 kV transmission line;- Song May 500 kV substation

1.1.1. SONG MAY- TAN DINH 500 KV TRANSMISSION LINESong May - Tan Dinh 500 kV transmission line traverses Binh Duong and Dong

Nai provinces. These two provinces are main economic zones of Southern Vietnam.Topography along the transmission line is quite plain mixed with low hills. Main

land use patterns are rubber tree forests, low hills, fruit tree gardens, dry crop fields andresidential areas. These land use patterns are separated by small rivers, water canals.

1.1.2. PHU MY- SONG MAY 500 KV TRANSMISSION LINEPhu My - Song May 500 kV transmission line traverses Ba Ria- Vung Tau and

Dong Nai provinces. Same as Binh Duong and Dong Nai, Ba Ria- Vung Tau alsobelongs to main economic provinces of Southern Vietnam. Topography in Project's areais also plain. Main land use patterns are rice field, dry crop fields, rubber tree forests andresidential lands.

1.1.3. SONG MAY 500 KV SUBSTATION500 kV Song May substation is located in cajuputs' plantation ("Tram forest" by

Vietnamese language). The land is belonged to Song May hamlet, Bac Son commune,Thong Nhat district, Dong Nai province. The substation is located 500 m far fromprovincial road No 767.

1.2. NECESSITY OF THE PROJECT1.2.1. Song May - Tan Dinh and Phu My- Song May 500 kV transmission line

According to the revised Master Plan N° 5 on Development of Power Sector, up tothe year a power generation capacity 4100 MW will be established and up to 2010, theinstalled capacity will be reached to 5300 MW. With that large amount of installedcapacity, the power network needs to be very well designed in order to ensure safe andreliable operation.Solution for strengthening of transmission network of Southern provinces

PHU MY - SONG MAY - TAN DINH 500kV TRANSMISSION LINE & SONG MAY 500kV SUBSTATIONPOWER ENGINEERING CONSULTING COMPANY No.3 PAGE 2

ELECTRICITY OF VIETNAMSOUTNERN POWER PROJECT MANAGERMENT BOARD (SPPMB) EIA

As it was specified in Master Plan N° 5, when the planned power generation plantswill come to operation, power capacity in excess will be quite large in Ba Ria- VungTau- Dong Nai region. In order to evacuate all power from Phu My complex to loadcenter of national power network the followings power transmission lines are proposed tobe built:

- Phu My- Nha Be- Phu Lam 500 kV TL (double circuit will be built for Nha Be-Phu My section) and Nha Be 500 kV substation;

- Double circuit 220 kV Phu My - Ba Ria - Vung Tau TL;- Double circuit 220 kV Phu My - Nha Be TL;- Double circuit 220 kV Phu My- Long Thanh- Long Binh;- Double circuit 220 kV Phu My- Cai Lay;- Double circuit 220 kV Phu My- Cat Lai- Thu Duc;- Double circuit 110 kV Phu My- Long Thanh;- Phu My 500/220 kV substation with 2 transformers 2 x 450 MVA;- Phu My 220/110 kV substation with 2 transformers 2 x 250 MVA;

Calculation of capacity trend of southern power network within period 2006, 2007reveals that in normal condition Phu My- Nha Be- Phu Lam 500 kV is heavily loaded(capacity for Nha Be- Phu My section is over 1500 MW). In case of fault in Nha Be- PhuLam 500 kV TL, some of 220 kV from Phu My, Nha Be 500 kV substation will beoverloaded. From 2007 to 2008, Nhon Trach power plant with capacity of 600 MW willcome into operation. The load on Phu My- Nha Be 500 kV will be increased. Voltage atending load subject is -5% bellow allowable amplitude. If fault is happen in Phu My-Nha Be 500 kV TL or in Nha Be- Phu Lam 500 kV TL, the southern power network willnot be stable. This can be lead to power outage in the region-wide or nation-wide.

The solution for overloading situation of southern power network is to construct500 kV Phu My- Song May- Tan Dinh, in which the Phu My- Song May section isdouble circuit. Other solution options have been discussed more in details in FS report ofthe Project.

1.2.2. Song May substation

Phu My power complex is largest generation source of southern part of Vietnam.Phu My- Song May- Tan Dinh 500 kV will contribute to evacuate power from Phu MyPower Complex. The TL is also transfer power to the load center of southern part ofVietnam. Other 220 kV transmission lines such as Phu My- Long Thanh, Phu My- CatLai, Phu My- Nha Be also transfer power to Ho Chi Minh city - load center of powernetwork.

Power demand in Dong Nai region is supplied only by Long Binh 220 kVsubstation, the substation is also received power from Phu My Power Complex. Power



capacity transferred from Long Binh to Ho Chi Minh city through 220 kV Long Binh -Thu Duc TL is quite low.

At the end of 2005, early of 2006, transmission capacity of Phu My Long Binh,Phu My- Cat Lai, Phu My- Nha Be will be totally full. If the fault will be happen in oneof these circuits, other TLs can not stand for such overloading capacity. In themeanwhile, the 220 kV Long Binh - Thu Duc is not fully loaded yet and has no source ofpower supply. If voltage fault will be happen in Long Thanh - Long Binh 220 kV, DongNai region will be lacked of power supply.

Song May substation will consolidate power supply for 220 kV TLs. Long Binhand Song May region will be supplied by two big sources, one comes from Phu My,another is from Song May 500 kV substation through 500 kV TL.

1.3. OBJECTIVES OF THE PROJECTThese three subcomponents of the Project are closely related one to each other.

The main objectives of the Project are:- Evacuate all installed power capacity of Phu My Power Complex to national

power grid;- Supply electricity for Bien Hoa, Ho Chi Minh city through 500 kV Song May

substation, 220 kV Song May- Long Binh transmission line.- Together with 500 kV Tan Dinh, Tri An hydropower plant, 500 kV Song May

substation will support for supplying electricity for Binh Hoa, Binh Duong and HoChi Minh city.

- Create the closed power grid linkage between different regions in Southernprovinces of Vietnam;

- Ensure safe, reliable, optimal operation of national power network, decreasepower losses; increase production efficiency for Electricity of Vietnam.

Ditch for cableOne part of construction of substation is construction of underground ditch for

installation of cables. Underground ditch is usually constructed by reinforce concrete,lowering to water collector. Ditch's width is 1200 mm, 600 mm, 400 mm, depth is 700mm. The cover of ditch is made also by reinforce concrete and it is 6 cm in thick. Slopeof ditch is about 0.05% to enable water run off.

Transportation ways inside substationWays inside substation are used for transformer transportation and for walking

during operation phase. The ways are made by concrete structure with rammed earth,gold dust underground.

Water supply for substationThe substation will require water for fire extinguish and water for daily

consumption of operating staff. Underground water will be exploited for water demand.Consumption water will be treated to meet safety requirement.

Waste waterDrainage system is designed for whole substation including rain water run off,

waste water treatment. The water released from drainage system is meeting the Vietnam



standards for waste water category B. The impact to the environment is very limited interm of waste water.

Sanitary waste water will be treated by septic tank before discharge into surfacewater body. Waste water after treatment will meet the requirement of TCVN 6772-2000 -Standard for sanitary waste water.

Waste water occurred after fire extinguish will be collected into oil spill collectorsystem. Oil and water will naturally separated by gravity - oil will float on water surface.Waste water will be let out by tubes at bottom of tank and discharged into sanitary wastewater system of the substation.

Solid waste

Main portion of solid waste of Song May substation is produced by working staffin the substation. There will be about 10 persons working in each working shift. Thereare three shifts per day. If every staff produces 0.3 kg of solid waste/day, every day theamount of solid waste produced will be:0.3 x 10 person x 3 shifts = 9 kg.

In project area, there is a local solid waste collection system which is establishedby local habitant. Solid waste of the substation will be collected by this collection system.The solid waste of the substation will be consisted of wiping materials, papers, remainingpart of wrapping paper, plastics, glasses, food cans etc.

2 Selective topping and clearing of - Trees within ROW need to be cut.ROW vegetation - Trees outside of ROW if their height can cause risk for

TL will be topped according to Decree 54 as specified inSection 2.6.

3 Material delivery and distribution - Construction material such as sand, gravels, cements,iron, steel need to be transported to construction sitessuch as foundations, substation.

- These construction materials usually are supplied bylocal suppliers.

- Separated steel parts of towers will be transported tosites, where the tower will be installed.- Electro-mechanical equipment need to be importedabroad and will be transported to substation by mainnational, provincial and district road system, which isquite developed in Project's areas.- Large trucks and equipment will move material anderect the line, with most activities occurring at structuresites. Temporary access to structure sites by heavyequipment will be along the ROW or, where availableand to avoid sensitive areas, from adjacent roads.

4 Augering and setting concrete - Usually size of foundation is 12m x 12 m in width andfoundations 2.5 m in depth.

- Concreting of foundation will be made on site requiringlarge area for construction preparation (gathering of

Activities Descriptionmaterial, metal parts of the foundation and tower).- Normally working time for preparation of foundation(soil excavation), concreting is about 2 weeks for soilexcavation, 1 month for concreting.

5 Structure erection - Tower is erected on site. For this erection, a larger areathan area of foundation will temporarily be acquired forpreparation, gathering of material, camping site forworkers;

- Winch is required for installation of towers. This issmall mechanical machine used at the tower erection site.This machine is small so it can easily transport to eachsite.

6 Conductor and shield wire - The main issue is safety of workers during installationinstallation of conductors and shield wire.

7 ROW maintenance - Maintenance would occur over the life of the proposedProject and would involve periodic vegetation clearanceand topping of trees.- Except in special access situations, permanent accessroads are not maintained.- ROW are trimmed or cleared of potentially conflictingvegetation about every two weeks.- Operation of the transmission line will have to complywith the Decree 54 on Protection of ROW for highvoltage transmission line.

DESCRIPTION OF ENVIRONMENT IN THE PROJECT AREA

3.1. PROJECT AREAThis 500 kV Project will be constructed in three provinces, covering 6 districts,namely:

1. Ba Ria - Vung Tau (7.75 km):* Tan Thanh with 1 commune

2. Dong Nai (72.117 km)* Long Thanh with 2 communes* Cam My with 4 communes* Thong Nhat with 7 communes* Vinh Cuu with 2 communes

3. Binh Duong (27.349 km)

* Uyen Hung with 2 communes* Tan Uyen with 2 communes* Thu Dau Mot town with 1 commune

The total length of the lines is nearly 108 km (not included are the connectionsto different distribution networks at Song may station). The lines are shown in Map 1.Project area.

3.2 NATURAL ENVIRONMENT OF THE PROJECT AREA

TopographyThe topography of the project area is very much consistent over the length of

108 km. It could be characterized by low hills mixed with flat land built upon thealluviation from small streams/rivers. The elevation of the area is going up from 1-2mabove sea level at the eastern end (Phu My) to 5-8m at the Western end (Tan Dinh).

At the beginning of the line (in Ba Ria Vung Tau) there is a small section(about 500m length) going through secondary mangrove. Other part of the TL ismainly crossing industrial trees' plantations such as cajuputs, cashews, rubbers andfruit gardens of the local people. Topography of the Project's area can be assessed asfairly plain and transportation roads are quite dense and convenient.

The elevation of the project area is higher than the height of floods at 1%frequency and no part of the area is under long-time inundation.

GeologyAccording to FS study of Phu My- Song May- Tan Dinh transmission project,

there are two main geomorphologic types existing in the Project's site.



* Eroded and denuded geomorphology: this form is presented in area with lowhills. The topography of this area is fairly plain and the rate of water run off isquite low. This form of geomorphology is resulted of weathering from basaltrocks.

* Alluvial plain geomorphology: This area is presented in low land in betweenhilly sites. This area is plain and was formed from sedimentation of silts, soilfrom other higher areas.

Results of geological survey for FS study reveal that geological conditions ofthe Project's area are quite consistent and stable. Drilling has been made for everyfoundation position and it is shown that geological structure is gravel, latrines, whiteand dark clays. These materials are strongly weathered.

ClimateThe Project area is located entirely in the Southeast region under influence of

monsoons, which is characterized by two seasons in the year: dry season fromDecember to April and rainy season from May to November. The average temperatureis close to 26-27°C with an difference of 4-50C between the hottest and coolest monthin the year. The temperature could go up as high as 400C in March/April and as low as18.1°C. The temperature of the eastern end of the project area varies less than that ofthe western end due to the impact of wind from the South China Sea.

The average number of sunny hours is estimated to be 2,500 with the most ofsun shine in March.

The rainy season brings most of the precipitation, which could be up to 2000mm/year. During the dry season the rainfall makes up only 15% of the total annualrainfall. This poses a very serious problem for the construction works of the 500 kVlines.

Typhoons are also a significant feature of the project area. Located near thecoast of the Southeast region, this area is prone to typhoons, which could occur duringthe months from September to November.

HydrologyThe project area has a variety of streams/rivers. Most of these are small

streams, collecting water for Dong Nai river system. These streams do not have tidalregime. The mangrove area near Phu My power station, part of the Thi Vai river, isunder tidal regime, with an difference between high and low tide of about 1Sm.

Water qualityThe water in the streams/rivers in the project area is under heavy pollution by

runoffs, discharges from agricultural and domestic activities in the area. During dryseason the water level of the small rivers/streams is quite low, just enough to providewater for the plantations along the small rivers/stream. During rainy season the watercould go up very high during floods, washing away dirt, debris etc. However thesestreams/rivers are the main source of water for a proportion of the population outsideof towns.



SoilThe main types of soil in the project area are:

* Alluvial soil: found mostly in the flat land areas and along small rivers/streams* Feralite soil: found in the hills* Saline soil: found in the mangrove near Phu My power station

The existing soil types are easy subjects for run-offs during floods and dust creatingunder dry conditions.

Air qualityAlong the 500 kV lines there are some urban areas, industry zones and road

junctions. The road junctions are points of heavy air pollution caused by combustionengines. The most serious contamination is SO2 concentration, which could go up 10times of permissible concentration in dry seasons. The urban residential areas are theleast polluted while the industrial zones have managed to keep the pollution level closeto the permissible levels.

EcosystemThe typical ecosystem along the proposed 500 kV line is plantations of

perennial industry crops mixed with annual cash crops. The common industry cropshere are cashew nuts, rubber, pepper, coffee. Fruit trees are also found in the gardens.

These plantations are set up along roads, streams. Up on the hills are also smallsecondary forests or cassava which requires little of water.

In the low flat land with abundant water there are also small rice fields for theself-subsistence by the local farmers.

The mangrove area near Phu My Power station is a secondary mangrove. Theexisting mangrove has Avicennia alba, Rhizophora apiculata and Brugiera parvifloraas the main species. Local population are using this mangrove as fuel wood source fortheir own use. However this mangrove is being converted by the local residents intoshrimp farms because of the attractive profits it could bring in.

Protected areasThe project area is far from the major centers of biodiversity in Vietnam. The twoneraest protected area are the Can Gio mangrove belong to Ho Chi Minh City (about60 km away as the crow flies), Bien Lac - Nui Ong belong to Lam Dong province(about 40 km) and Binh Chau- Phuoc Buu belong to Ba Ria- Vung Tau province(about 30 km).There protected areas are very far from Project sites. See Maps of Project for moredetails. The Project will not cause any impact to protected areas.

Historical and Cultural propertiesAccording to the Map of Nature Conservation Areas of Vietnam, there in no historicaland cultural site accredited in three provinces: Binh Duong, Dong Nai, Ba Ria- VungTau.

ASSESSMENT OF ASSOCIATED AND POTENTIALENVIRONMENTAL IMPACTS

4.1. METHODOLOGY FOR IMPACT ASSESSMENTThe pathway followed in the identification/assessment/evaluation of the

potential and associated impacts of the proposed Project on the biophysical and socio-economic environment and the development of mitigation measures for significanteffects. The assessment approach generally involves matching the variousphases/activities of the proposed project with the various components of the projectenvironment. Their interaction may lead to a change in or impact on the environment,hence mitigation measures are proffered in order to reduce, offset or ameliorate suchchanges. However, for effective functioning of such measures, a social andenvironmental management plan is developed to cover the entire life cycle of theProj ect.

4.2. CLASSIFICATION OF THE IMPACTS

In order to further describe the nature and duration of the various projectactivities on the biophysical and socio-economic environment, identified impacts werefurther characterizes as direct/ indirect, beneficial/adverse, normal/abnormal, shortterm/ long term, reversible/irreversible, cumulative and residual.

Beneficial impacts: there are impacts that would produce positive effect on thebiophysical or socio-economic environment.

Adverse impacts: these are impacts that may result in:

- Irreversible and undesirable changes in the social and/or biophysicalenvironment;

- Decrease in the quality of the biophysical or social environment;

- Limitation, restriction or denial of access to or use of any component of theenvironment to others, including future generation; and

- Scarify of long term environmental viability or integrity for short termeconomic goals

Direct impacts: these are impacts resulting directly (direct cause-effect consequence)from a project activity.

Indirect impacts: these are impacts that are at least one step removed form a projectactivity. They do not follow directly from a project activity.

Normal impacts: these are impacts that will normally be expected to follow aparticular project activity.

Abnormal impacts: an impact is considered to be abnormal when it follows a projectactivity as against sound prediction based on experience.



Short term impacts: these are defined as impacts that will last only within the periodof a specific project activity.

Long term impacts: these are impacts whose effect remains even after a specificproject activity.

Reversible impacts: these are impacts whose effects can be addressed on applicationof adequate mitigation measures.

Irreversible impacts: these are impacts whose effects are such that the subject(impacted component) can not be returned to its original state even after adequatemitigation measures are applied.

Cumulative impacts: these are impacts resulting from interaction between ongoingproject activities with other activities, taking place simultaneously.

Residual impacts: these are impacts that would still remain after mitigation measureshave been applied.

4.4. ASSESSMENT OF PROJECT ENVIRONMENTAL IMPACTS

Table 4.2. Assessment of Project Environmental Impact

Project phase/ Associated and Impact characterization Impact analysis

Environmental aspect potential impacts

Pre-construction/ Site 1. Risk of road accidents Adverse, direct, normal, - Due to increase of transportation of the existing toad system in the Project provinces, the risk of

Preparation/ due to increased traffic irreversible, cumulative increase traffic jams, accidents will be increased.

Construction on local roads dudng - The transportation of construction materials, equipment of the Project will require heavy trucks,

mobilization of heavy especially for equipment of Song May substation.equipment

- Duration of construction work is quite short, 1 year for whole project Phu My - Song May - Tan

Dinh transmission line (from 10/10/2005 to 10/13/2006) and 1 year for project Song May Substation

(from 6/2006 to 6/2007), the transportation therefore will increased only in short period of time.

Equipment of Song May substation is quite limited. The most heavy and long size equipment are

three 220 MVA (500/220 kV) transformers.

- Material and equipment are transported to many places along the over 110 km of the Project

provinces. In this area the road system is good; the traffic is already very intensive. Additional

transportation required by Project will cause adverse but not very significant impact on roads in the

Project area.

2. Socio-cultural conflicts Adverse, direct, - Three construction crews will be required for Phu My- Song May TL, two to three crews will be

due to difference in abnormal, short-term, required for Song May- Tan Dinh TL, for Song May substation at least three crews will be required.

customs of migrant reversible Each crew will consist of 70 to 80 persons; about 60 persons will need to stay in campsite.

workers and local - Campsites are selected in remote areas that are far from residential areas. The campsite can also

be used for assemble of construction materals, steel parts of towers, cement, soil and gravels etc.

- Conflict with local people can be happened due to the following reasons:

- Difference in custom and tradition

- Difference in income

- Encroachment of workers to historical and cultural sites of local peoples







- Interviewing of local people in other 500 kV projects shows that the difference in custom and

tradition can be occurred when construction workers go to sleep later those local peoples. In evening

time workers like to sing, so it causes noise to local people who go to sleep much earlier than

workers. This group of workers stayed for excavation of pole foundation. Duration of their stay in thissite lasts for two weeks and they will move to another foundation. This "conflict" is happening only in

short perod of time.

- Similar situation can be happen to Phu My- Song May - Tan Dinh Project, when the group of

workers need to stay out of their campsite for excavation of tower foundation which is far from their

campsite for few nights. But this duration ins quite short. The places that near residential areas areTan Uyen district, Thu Dau Mot township, Cam My district.

- Workers tend to save money than spend money. The impact therefore can be considered as minor

negative.

3. Change in Adverse, direct, normal, - Contractors for construction of 500 kV TLs and substation will most likely come from out of the

demographic pattern/ reversible, cumulative area (Ba Ria, Vung Tau and Binh Duong provinces), but less skill workers may come from local

disruption of socio- provinces. Since SPPMB would be contracting much of the labor force from out of provinces, a large

cultural pattern portion of the labor force will remain in the Project area for the duration of construction. The

construction period of the each component of the project is considered short term, therefore, no

member of the labor force would be expected to permanently relocate their families, so employmentpatterns in the area unlikely to change as a result of the project. Over the long term, operation of the

Proposed project or alternatives would require very few employees; they will be staffs of Power

Transmission Company 4 - a local company taking care of operation of the Project.

- Three working crews will be working for construction of Phu My - Song May TL. Two or three other

crews will be selected to work for Song May - Tan Dinh TL. For construction of Song May, one big

construction crew will be hired for construction work. Other one crew will be hired to work for

installation of equipment, substation and other technical work. These working crews will camped

along the ROW of TLs and near the proposed substation. Number of workers in each crew is

estimated as 73 persons. One third from them will be from local areas. About 60 will need to live in

campsite. This amount of workers from outside is quite considerable and can cause certainenvironment and socio-economic effects, but there would not be any significant impact on change of





demographic pattern or disruption of socio-cultural pattern.

4. Introduction of Adverse, direct, - Gatherng of large amount of workers in one campsite can be a good chance for spreading out of

communicable disease abnormal, reversible, communicable diseases between workers and between workers and local peoples. Even though the

into project communities cumulative, residual contact with workers with local is very limited due the fact that their campsites will be far from

residential areas. Although, the TLs is transverse some thinly populated areas (see table 2.6 for

more detail), however project have a good health care, public hygiene plan such as health checking

periodic, issue medicine free for worker to prevent popular disease (diarrhea, dysentery etc), spray

chemicals to kill mosquito at construction camp etc; so working activities will not much happen in

crowded areas, so introduction of communicable disease in to project communities and vice versa is

very limited and not significant.

5. Air/noise pollution Adverse, direct, Air quality

from increased vehicular abnormal, short term,movement reversible, cumulative, - The following impacts to air quality associated with the Project has been identified:

residual - Particulate PM1 o emission from construction disturbance:

Many construction activities associated with the Project, such as earth-moving operations (e.g.

augering and pole access road development) and soil disturbance from construction equipment

(especially from travel over unpaved roads), would generate PM,0 emission. PM10 emission can vary

greatly depending on the level of activity, the specific activities taking place, and weather and soil

conditions.

- Construction equipment exhaust emissions of ozone precursors (ROC and NOx)

Emission levels for construction activities vary with the type of equipment, duration of use, operation

schedules, and the number of construction workers

- Earthwork is main source of air pollution during construction of tower foundation and substation.

- Total volume of earth needed to be excavated, leveled, backfilled in the Projects are described as

follows:

- At Sona Ma substation: 113.538 m3, in which excavating earth is 50,610 m3 and leveling



I~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~





earth is 62,928 m3

- Along Phu My- Song May TL: 342147 m3, in which excavating earth is 178,988 m3 and

backfilling is 163,159 m3

- Along Song May- Tan Dinh TL: 211562 m3, in which excavating earth is 110,837 m3 and

backfilling is 100,725m 3

- Air pollution will caused by dust, toxic gases emitted from vehicles and construction machines. The

affected receptors are houses surrounding the construction sites and roads used for transportation of

construction materials, equipment. Based on experience on another projects, at a distance 50 m far

from construction sites, in dry season, at peak construction hours, ambient air quality may not meet

the TCVN. However, two segments of the TLs are about 120 km long. Estimated number of the

tower is 400 towers (300m/tower). This will spread out the air emission caused by construction

vehicles and machines.

- At Song May substation, the present air quality is quite good. The air emission will last for the

construction time (1 year). The receptor will be cajuput trees. In theoretically, the dust deposited in

the foliage it will reduce the photosynthesis capacity of the trees, therefore the growth of cajuput tree

will be reduced. This effect is inconsiderable because cajuput trees at this site are maturing, strongly

growing; sunlight in this area is very intensive; only trees near substation will be affected.

Noise

- According to Environmental report made by DONRE of related provinces (2003), the present noise

levels in Project area are still low and meet Vietnamese national standards. Some parts of the TL is

going across residential areas with quite extensive human activities. Noise level in these areas is

also not excess the TCVN.

- Transportation of materials and equipment for the Project will use the existing road system which is

quite well developed in Dong Nai, Ba Ria- Vung Tau and Binh Duong provinces.

6. Loss of cultural and No impact - During designing of the Project's components, protection of historical and cultural property wascarefully considered.





Project phase/ Associated and Impact characterization Impact analysisEnvironmental aspect potential impacts

historical properties - Referring to Phu My - Song May TL, in section G3A to G4B (see Table 2.5.), the TL is designed to

turns right (angle width is 10 23') to avoid encroachment of Thua Duc church and oratory of ThuaDuc commune, Cam My district, Dong Nai province.

- Protection of other infrastructure is also considered by the consulting and designing staffs. Section

G4A to G6A of Phu My - Song May is also needed to turns left to avoid protected area of proposedLong Thanh Intemational Airport.

- The TLs are high voltage so they are design to go far from residential areas. Small historical and

cultural properties that commonly presented in rural area of Vietnam, therefore, would not beaffected by the TLs.

- Construction of the Project will require a lot of excavation of soil for foundation (2.5 m depth inaverage), substation basement, the Project owner is fully awarded that if there is any valuablehistorical and cultural property found in underground, it should be inform immediately to local

Department of Culture and Information for further consideration.

7. Health risk due to No impact - Along the routes, there are agricultural lands or land for plantation of industrial trees. After theexplosive material and Vietnam War, there was a program for land mine, toxic substances and other explosive materalresidual chemicals from clearance in these areas. The proposed TLs and substation are not located in remote area with

the War limited human touch, so there is no risk of land mine, explosive material during construction andoperation of the Project.- No toxic chemical will be used for any activity of the Project. There would be some oil, gasoline,grease used in maintenance of construction machines. These chemicals are used in very limitedamount; they can not cause any hazard to the environment and human health. Therefore, the impactcan be considered as no impact.

Construction 8. De-vegetation/loss of Adverse, direct, normal, - Impact includes the direct removal of plants or wildlife habitat, wildlife mortality caused by

Vegetation clearing at vegetation at short term, reversible construction vehicles and the dsk of bird collision with tower and transmission lines.construction camp and construction camp, and - Main land use pattern, vegetation of the Project's area is industrial plantation. The trees that will bealong ROW along ROW cut for ROW, access roads and substation are mostly planted trees such as cashew, rubber, mango,

coconut, longan, cajuput etc. Number of secondary growth mangrove trees is estimated as 42,000trees. These trees are located in the area with very active human touch with shrimp farming, they arealso the only natural trees that will be cut by the Project.






9. Loss of economic Adverse, direct, normal, - During clearance of ROW, access roads and substation, there are 493,146 of economic trees will

trees arising from long term, residual be cut. (See Table 4.3. for detail)

creation of ROW and - Owners of acquired land will receive compensation and they will use compensation money for

access roads expansion of their plantation. The production will be lost for the first years, after five years the

replanted areas will growth in good condition an can give product for the land owners.

- Only in some cases land owner will not intend to use compensation money for re-planting. These

case can occur when:

- The lost land is very small in comparison with remaining land of land owners. It nor

necessary for them to plant more trees to replace cut trees.

- Land owner has other plan to for their income generation; the money can be used for this

purpose.

- There is no more land for replanting of trees.

10. Loss/ disturbance of Adverse, direct, normal, - The areas that need to be cleared for ROW and access roads are small in comparison with the

wildlife due to habitat long term, residual remaining part of original land use.

loss/ fragmentation from - The presentation of wildlife in the Project area is really observed. Observed animal species are

vegetation cleanng along common birds, snake, bees, and rodents. Wildlife large animals are not observed along the ROWs;

ROW and access roads

- The clearing of ROW will cause loss of habitat and habitat fragmentation, but there will not be no

fence created so moving of animal, insects will be adversely affected but not totally limited. Habitat

fragmentation may occur only in large industrial plantations crossing by the Project such as cajuput

tree forest in Vinh Cuu, Tan Uyen, Tan Thanh, Long Thanh districts.

- Gardens that are crossing by the TL are in much smaller scale than industrial plantation, human

touches in these areas are quite intensive. The impact on wildlife in these areas by construction of

the Project will be locally and short term.

- Song May substation is located in cajuput plantation of Bac Son commune, Thong Nhat district,






Dong Nai province. This area is located 120 m far from Song May Water supply plant, and in cajuput

planted forest, there would be no significant impact of the substation to the wildlife in term of

biodiversity loss or habitat fragmentation.

11. Employment of local Beneficial, normal, short - Local labors will be hired for simple work such as soil excavation, manual transportation of

labor term construction materials and equipment.

- Amount of work is quite considerable and brings good benefit for local labors. There are 6 squads

to execute whole the project Phu My - Song May - Tan Dinh transmission line. In which, three

squads will execute the project Phu My - Song May transmission line, about 20 km the line for each

squad and others will execute the project Song May - Tan Dinh transmission line, about 13 km the

line for each quad. Number of worker for each squad is about 73 men; in which, 70 men is direct

labor, others is manager. For Song May substation, number of worker is 110 men; in which, direct

labor is 95 men, indirect labor is 3 men, others is manager.

Construction 12. Soil/ groundwater Adverse, indirect, - Fuel will be stored during Project construction. This fuel is used for equipment, simple maintenance

Fuel storage during contamination from abnormal of machines, lubricants, and diesel generators (if there is any). Based on the experience from other

construction activities accidental leak or spill of projects, condition for storage of the fuel is very basic, with out adequate safety regulations.stored fuel at camp site - Usually, the fuel is stored within campsite. The simple maintenance will be carded out at the same

place or very near the campsite.

- The risk for contamination of soil, groundwater is highly potential.

- Application of proposed mitigation measures as described in Chapter 6 will reduce the risk and

impact to acceptable level and may eliminate the risk for groundwater pollution.

Construction 13. Change in Adverse, indirect, - The Project crosses or approaches Dong Nai river, many irrigation canals, secondary mangrove

surrounding land, vegetation cover before reaching to the river.

- One or two foundation will be located in area of secondary mangrove forest in Tan Thanh district of

Ba Ria - Vung Tau province. This mangrove forest is secondary and is not in good growing

conditions. So far, many shrimp farms are developing on the area. This site might be the most

sensitive site of water quality disturbance by Project activities because receiving water bodies(wetlands) are very near construction site. Even though there are some construction practices thatwill be employed to mitigate the potential for wetland and water quality impact.

- Da Ban and Song May stream are about 15 to 18 m wide. These water bodies are located far from

construction sites, so it will not receive any water runoff from Project activities.

- During construction of 500 kV TLs, adverse surface water quality impacts due to sediment loadingof excavated spoils could occur in wetland area (My Xuan commune of Tan Thanh district- My Thanhprovince) adjacent to the construction area or immediately downstream. Tower and access roadsconstruction activities that include scarping, excavation, grading, backfilling, excess soil disposal,and topsoil handling and replacement are likely to generate sediment. In particular, excavationactivities needed to prepared the concrete foundations for the towers will bring soil, sediment, rock,and perhaps water to the surface. River, stream, irrigation canals could be impacted by sediment

loading. The potential for high soil erosion rate can be happen in hilly areas such as in Vinh Cuu,

Tan Uyen districts (Dong Nai province.). But water bodies that the TL crossing are not as dense as in

other Project's areas. As described above due to the fact that constructions site will be located very





far from surface water bodies such as Dong Nai river, Da Ban, Song My stream, so this impact will

be very less likely happen and considered as non significant impacts.

15. Noise and vibration Adverse, direct, normal, - Noise level and vibration will occur in construction site for tower foundation, Song May substation.

from construction short term Heavy machines will be required for construction; they can be heavy vehicles, bulldozers, compactor,

equipment and and concrete mixing machines. etc. These machines will increase noise/vibration level in

machines construction sites. All of construction activities will be carried out in day time. Tower foundations

usually located in industrial tree plantations, in garden or rice fields. In some cases they are located

near residential areas such as near the roads, in rural residential areas where the population density

is rather lower than other places. At this stage, the exact locations of the towers are not yet exactly

defined. But before construction work start, workers need to prepare construction yards, which is

quite large in comparison with original place needed for foundation itself. Project owner would pay

compensation for permanent and temporary land acquisition. Houses exist in that areas need torelocated or removed. Principle, no person need to stay near construction area. Therefore, the

impact would not be directly affected local people in term of noise and vibration. Furthermore, theduration of construction in each foundation site with heavy machines will last within 1 month. For

Song May, this duration is longer but the substation is located in large scale cajuput plantation, the

impact (if there is any) will not cause significant impact to local people.

- Noise impacts during construction time are generally short-term nature. Approximate noise levels

from construction of the proposed Project were estimated based on the construction equipment

characteristics information provided in Table 4.8.

- Construction noise can be created from on-site and off-site sources.

- On-site noise source would primarily consist of the operation of heavy duty diesel and gasoline-

powered construction equipment. Noise level from these individual pieces of construction equipmentrange from 70 dBA to 98 dBA at a distance of approximately 15 m (See Table 4.6.) It should be

noted that noise levels are calculated based on the assumption that noise from a localized source is

reduced by approximately 6 dBA with each doubling of distance from the source of noise. Two types

of noise are associated with on-site construction activities: intermittent and continuous. The projectedmaximum intermittent noise level associated with the construction of TLs structures would range

from approximately 82 to 92 dBA at 15m, 76 to 87 dBA at 30 m. Intermittent construction noise could







be annoying to sensitive receptors within 300m of the construction activities. It is estimated that

continuous noise levels from the TLs construction activities at 15 m would range from 70 to 77 dBA.

At 30 m, noise levels would be approximately 63 to 71 m. These noise levels are meet TCVN

applicable for daytime at residential areas. Main receptors of noise of the Project are actually notresidential areas, but plantation sites. No construction activity is allowed to carry out in night timenear residential areas. So this noise level would not cause any significant effect to local people.

- Off-site noise sources would include vehicles commuting to and from the job site, as well as from

trucks transporting material and equipment to the staging areas or construction ROW. Off-site noise

during construction would occur primarly from commuting workers and from truck trips to and from

the construction sites. As described in other sections, the construction workforce for the projectwould average 60 to 70 persons for each crew. It is anticipated that most workers would be meeting

at one of the staging areas (tower's foundation) and would travel to the construction in vehicles(motorbikes, vans or buses). It is also assumed that truck trips would be required to haul structures,

conductor line and other material to the construction sites. The peak noise levels (approximately 70to 75 dBA at 15 m) associated with passing trucks and commuting workers vehicles would be shortterm in duration and would generate adverse but not significant impact.

16. Respiratory infection Adverse, direct, normal, - Construction workers will be the main receptors of the toxic fumes such as VOC and NOx as

due to inhalation of toxic short term described in impact No 5.

fumes by onsite workers - This impact seems to be invisible but the health of workers will be affected. Workers will feel tired,

during welding activities headache, being dazzled... for longer term their lung will be affected. Safety equipment are

recommended to ware during welding as described in Chapter 6 to minimize health effects to welding

workers.

17. Risk of electrocution Adverse, direct, normal, - The risk for electrocution and burns will be highly potential for welding workers. See mitigationand burns during short term measures suggested in Chapter 6.

welding

18. Falling from height Adverse, direct, normal, - Referring to the other similar projects, the accident of falling from height during tower constructionduring tower short term and maintenance. The main reason is workers not strictly following the safety regulation, procedures






construction and or unqualified persons take part in the welding process;

maintenance - This impact is mitigable. By strictly follow the safety procedures and some responsible for overall

looking for this issue at the construction sites.

19. Loss of land use due Adverse, direct, - Temporary construction disturbance

to placement of towers/ abnormal, long term A variety of construction activities will temporarily disturbed existing land use. In addition to noise,

Number of households dust, traffic, and visual disturbances to existing land uses and on industrial and agricultural lands

to be affected within the ROW would be temporarily lost as a result of removing vegetation, grading, overland

travel, site preparation, and assembling and erecting structures. Construction activities would also

result in a temporary loss of the use of agricultural, industrial tree plantation out site the ROWs as a

result of ovedand travel, constructing new access routes, and constructing and using staging areas.

However these losses would be more severe in case of permanent crops such as rubber, cashew,

mango, longan etc. these trees require number of years (5 year in average) to re-establish to

productive levels. In addition, soil compaction may occur as a result of construction equipment and

activities, necessitating remedial activities to restore previous land use patterns.

Since precise locations for towers, access roads, and staging areas have not been identified,

assumptions were made about overall disturbance, based on Project description information (e.g.

number of tower per km, size of staging areas, access roads). The overall amount of land that would

be subject to physical disturbance would be about 4,600,000 m2 (equal to 425.5 ha). From this,

about 425 m2 will be permanently occupied, the remaining part (4,,250,000 m2) will be used one

temporarily. Short term land disturbances are significant in Song May substation site. in intensive

farming in Thong Nhat, Vinh Cuu, of Dong Nai province. The majority of short term land disturbance

is Agricultural cultivation land and industrial crops land. (See Table 4.4. for details)

Tan Uyen district ,Thu Dau Mot township of Binh Duong province. The duration and extent of the

impact can be reduced through implementation of mitigation measures described in Chapter 6.

- Long term conversion/Loss of productive agricultural land

In intensive farmed areas, transmission towers and access roads may permanently displace

agricultural production or other industrial plantation production. An estimated 12m x 12m = 224 M2






per tower would be lost, and an additional area would be lost to access roads. Construction of

access road will only be required in very few cases. All of the TLs can be quite easy to access due to

intensive human activities in whole these three provinces. The proposed TLs include amount of

agricultural land (rce fields, fruit gardens etc.) and intensively farmed lands for industrial trees.

The loss of productive farmland would result in financial impact on land owners. Crop values have a

wide variation from year to year. Because of this wide fluctuation, it is not practical to attempt to

quantify a define value per ha for productive land that may be lost to the Project ROWs.

Number of households that loss their land (agricultural and residential land) is 66 HHs for Song May-

Tan Dinh section; 203 HHs for Phu My- Song May section); 1 HH for Song May substation; and 59

HHs for Connecting routes. See Table 4.5. for Number of affected households.

20. Permanent loss of Adverse, direct, normal, - As it was discussed above in Impact analysis of impact No 19, and in Table 4.3. on Number of tree

economic trees along short term, reversible to be cut, there will be permanent loss of economic trees.

and within the vicinity of - Within vicinity of ROWs some trees with limited height can be replanted. But in the Project ROWs,

there are many agricultural and industrial trees that have height above permissible height within

ROWs. These trees will be never replanted within ROWs areas, but they may be replanted within

areas of access roads.

21. Induced secondary Adverse, direct, normal, - During construction activities the secondary development in the surrounding areas can be happen

development in the short term, reversible because of the following reasons:

surrounding areas during - Construction of supporting structures for the Project such as campsite;construction activities

- Bringing large amount of construction workers to the Project sites;

- Increase the demand for clean water, health service, solid waste collection, waste water

treatment and other public services.

- Other reasons.

- In some cases the secondary development brought by the Project will put higher pressure on

_________________________ _______________________ ___________available infrastructure. But this impact can be considered as less significant impact due to the






reasons such as: duration of construction time is short term and limited, every working crew is

equipped by medical kit bag for treatment of basic diseases, workers coming home every weekend,no family will be brought to construction sites by construction workers etc.

22. Engagement Beneficial, direct, normal, - Beside the induced secondary development which can put more pressures on local infrastructures

indigenous labor and short term, reversible such as health care services, clean water supplement, solid waste collection.... The engagement

suppliers and stimulation indigenous labor and suppliers and stimulation of local economy can be happen due to the following

of local economy reasons:

- Hiring of local labors;

- Purchasing of construction materials of local suppliers;

- Hiring local transportation company for transportation of material and equipment;

- Increase of public services which can result in increase income generation for local peoples;

- Increase consumption of agrcultural products (such as fruits, rice, meat etc.), public

services (such as food shops, barber shops, mechanical maintenance for vehicles) by

construction workers and contractors.

- This impact is beneficial for local peoples of the Project areas.

Operation/ Maintenance 23. Nesting site and Beneficial, direct, normal, - Theoretically, the tower of TLs can be a good place for nesting sites and perches for birds.

Power transmission along perches for birds long term - By observation along another 500 kV, 220 kV TLs, there is not yet any evidence of nesting site and

the lines perches along the TLs so far. It may because that along the TLs there are many better places for bird

nesting such as dense tree in industrial plantations, fruit gardens etc. The same situation may be

happen for Phu My- Song May- Tan Dinh TL. But this impact if will be occurred will be beneficial,

direct, long term impact.

24. Potential of Adverse, direct, abnormal - EMF exists in the environment both naturally and as a result of human activities that use electricity.

epidemiological Additional EMF will be generated as a result of the proposed Project. Technical designer of the

problems to workers Project has adopted limit of EMF is 5 kV/m as specified in Decree 54 on Protection of ROW of high

exposed to (and






residents near to) voltage TL.

transmission line - According to the Vietnamese Power Sector Standard (1994), durations allowed to work under EMF

genetromagneticnfields intensity of < 5 kVlm, 10 kV/m, 15 kV/m, 20 kV/m and > 25 kV/m are unlimited, 3 hrs, 1.33 hrs, 0.5electromagnetic fields hrs and not allow, respectively (Table 4.9).(EMF)

Field EMF Testing of the existing Phu My- Nha Be- Phu Lam 500 kV TLs

In 2004, EVN has carried out the measurement of electromagnetic field of 500 kV Phu My- Nha Be-

Phu Lam. The measurement of EMF program was focused on selected points within ROWs, in some

workshops within and outside ROWs. The obtained data shows that the EMF intensity is meet the

Vietnamese Standard. Results of the measurement are given in Table 4.8

The intensity of EMF in between of 500 kV and 220 kV also was measured to see whether there is

any EMF resonance from these two TLs. In these cases, EMF intensity is varying between 0.027 to

less than 0.04 kVWm. From the above indicated studies it may be conduced that there is no risk of

EMF intensity under 500kV TLs and between 500 kV and 220 kV TLs in the Project.

EMF intensity in 500 kV substation is higher than it is within ROW of TLs, in some cases it is higher

than 5 kV/m.

By following the technical standards for designing of 500 kV projects and power sector standards,

local people, working staffs of these 500 kV components will not be exposure to the risk of EMF.

Additionally, during conduction of this EIA study, hundreds published documents on health impacts of

500KV's EMF from world-wide internet were reviewed. However, there is not a document

demonstrated serious health problems caused by transmission line's EMF. In Ho Chi Minh City,

where is location of Nha Be - Phu Lam 500KV TLs; according to DONRE so far there is not any

complaint from health care authorities on health impacts of EMF (See Table 4.10 for reference data

from EVN).

- There are another points supporting for assessment of impacts related to EMF, they are:

- Electric field will not affect growth of crops and other plants;

- It has not been found that electric field is likely to bring any harmful influence to wild animals

in their action or health. When electric field intensity is up to 12 kV/m, domestic animals'







health and action are not affected at all. (EIA for East China 500 kV transmission projects,

2002);

25. Electnc shock and Adverse, indirect, - Impact of geologic hazard on the Proposed Project would occurred as described bellows:

burns to members of the abnormal, long term, - High potential exists for ground rupture due to presence of an active earthquake fault

public in the event of irreversible crossing transmission line alignment, with attendant potential for damage to the substation,

tower collapse or transmission lines, of other project structures.damage to transmission

wires - High potential exists of earthquake-induced ground shaking, which could cause surface

cracking along the TL alignment, resulting in attendance damage to the TL or other project

structures

- Potential for failure of construction excavation exists due to the presence of loose saturated

sand or soft clay.

- Presence of corrosive soils exists which would damage TL support structures

- Potential for settlement or ground subsidence exists due to soft, compressible or collapsible

soils.

- Geological study, analysis of soil properties has been carded out during FS . The result of

geological surveys reveals that geological condition is good for construction of the Proposed project.

Data on soil analysis and geological characteristics are available in the FS study. Soil is not

corrosive.

- Other transmission lines are existed in the area and there is no case that geological condition is not

good enough to support supporting structure of the TLs.

- Water quality was tested and the result reveals that water is not corrosive; no harm to tower's

structure can be occurred. There would probably no risk of corrosive soil and water which would

damage TL support structure.

26. EMF accumulative No impact In general, Song May - Tan Dinh TLs goes parallel and stands 60m apart with Pleiku - Phu Lam

with Pleiku - Phu Lam TLs. During designing and installing, consultant company considered EMF accumulation carefully to





TLs avoid impacts of EMF on local habitant healthy. Besides, according to result of EMF measuring along

500kV TLs which operating such as Phu My - Nha Be - Phu Lam 500kV TLs, EMF is 0.08kV/m (so

lower than regulation in Degree 54/ND-CP - 5kV/m) at site outside of ROW. Therefore, the impact

can be considered as no impact.

Operation/ Maintenance 27. Explosion and fire Adverse, indirect, - Based on experiences of other transmission substations, there is a risk of explosion and fire hazard

Song May substation hazard at Song May abnormal, long term at substation. The reasons for this potential risk are different case by case but it more or less relatessubstation to the technical operation of the Project. However the results of explosion and fire can be resulted in

causing contamination or pollution of air, soil.

- The explosion and fire can cause also disruption of power supply by power network. It can cause a

great loss to nation- wide economic development.

- Equipment for extinguishing of fire and containers for oil spills are designed for Song May

substation to minimize impacts to air quality, soil caused by explosion and fire hazard at Song May

substation.

Operation/ Maintenance 28. Fatal electric shock Adverse, direct, Induced currents and voltages on conduction objects near the proposed TLs represent a potential

- Maintenance of and severe burns to abnormal, long term, significant impact that can be mitigated. These impacts do not pose a threat in the environment if the

transmission lines workers during reversible, residual conducting objects are properly grounded, and the following mitigation measures is recommended to

maintenance work reduce the potential impacts of induced currents to less than significant levels.

- Vegetation clearing

along ROW and 29. Invasion of exotic Adverse, direct, normal, - Due to the situation that within the ROW only certain species of trees with limited height can be

access roads for vegetation species and long term, irreversible grown, so the invasion of exotic vegetation species can be occurred.

maintenance increases habitat

diversity along ROW and

access roads

30. Impairment aesthetic Adverse, direct, - The present of number of towers will impair aesthetic resources when the towers are located in

resources due to visual abnormal, long term, residential areas (please see table 2.6 for more detail). These residential areas are thinly populated,

presence of towers and reversible, residual and have some companies such as Tan Mai aluminum production, Nhat Anh company. This will

transmission lines make the location to have bad appearance.




Project phase/ Associated and Impact characterization Impact analysisEnvironmental aspect potential impacts

- In other places such as rubber plantation, gardens the TLs can have limited visual impact because

the area is large with good view already. The TLs will not impair the aesthetic effects.

Operation/ Maintenance 31. Soil or substation Adverse, direct, long - Oil that will be for transformers of Song May substation will not contain hazardous substances such

Use of oil, chemicals basement contamination term, reversible, residual as PCBs. From early of 1 990s, EVN has banned the usage of PCBs. So far the requirement of oil,during maintenance of lubricant used for Project need to meet IEC standards, this means that no PCBs is allowed to use.transformers and other - Furthermore, this impact can be consider as adverse but not significant due to the followingproject equipment reasons:

- Oil refilling for transformers will be done regularly by skilled staff;

- Containers for oil collection are designed to receive oil spill in case of accident or duringmaintenance.

- The volume of oil collector is as big as oil volume inside transformers.

PROJECT ALTERNATIVES

5.1. SONG MAY- TAN DINH 500 KV TLBased on topography, there are two alternatives were investigated and considered

for selection. Detailed descriptions of these two alternatives are described bellows.5.1.1. OPTION 1

The main advantage of this option is the TL is going along the existing 500 kVPleiku-Phu Lam transmission line. The TL therefore will be very easy to be accessed.The construction will be very convenient. Planning for land use of local authoritieswill not be fragmented due to ROWs creation. Socio-economic development of theareas will be less affected by the Project.

Total length of Option 1 is 39.592 km. The transmission line is started from 500kV substation. After crossing Dong Nai river, at point GIl, the TL turns right toapproach the left side of the existing 500 kV Pleiku-Phu Lam TL. At point G12, theproposed TL is 60 m far from Pleiku- Phu Lam TL. At point G12, the TL turns leftand continues to go in parallel with Pleiku-Phu Lam 500 kV TL. The end point ofproposed TL is bus bar of Tan Dinh 500 kV substation. The length of parallel sectionis 21.302 km.

5.1.2. OPTION 2The proposed option is the possible shortest distance, but still can avoid

crowded population areas, industrial areas such as Uyen Hung district and valuableagricultural land in many rubber farms.

Total length of the proposed option is 39.371 km. The section from Song May500 kV substation to point GIl is same as Option 1. From GIl , the proposed TL isgoing straight to Uyen Hung districts by going along belt roads of Uyen Hung district.Two times the proposed TL is crossing 500 kV TLs and reaches to point GI5. Frompoint G15 the proposed TL continues to go in parallel with Pleiku- Phu Lam 500 kVTL until end point at bus bar of Tan Dinh 500 kV substation (same as Option 1). Thelength of parallel section is 8.936 km.

Characteristics 0ption 1 Option 2LamOpinion of provincial people Agreement was reached No agreement was reachedcommittee.

SELECTED

5.1.4. ADVANTAGES OF THE SELECTED OPTION- There is no cross section with 500 kV TLs, therefore no need to spend high

cost for super high towers for cross sections;- The construction work will be more convenient because the line is easy to be

accessed;- The maintenance will be easy because many other maintenance access roads of

Pleiku- Phu Lam 500 kV TLs.- No need to cut off electricity in two 500 kV TLs if faults will be happened in

cross sections;- Binh Duong provincial people committee has agreed with the selected option

(Option 1).

5.1.5. DISADVANTAGES OF THE SELECTED OPTION- The selected option is longer than the second option about 200 m. This length

is not considerable;- The number of affected household is 13 households more than the second

option.

5.2. PHU MY - SONG MAY 500 KV TRANSMISSION LINEPhu My- Song May 500 kV is started from bus bar of Phu My 500 kV substation

in My Xuan commune, Tan Thanh district, Ba Ria - Vung Tau province. The endpoint of the TL is bus bar of Bac Son commune, Thong Nhat district, Dong Naiprovince. Total length of the TL is 63.684 km and the TL is crossing Ba Ria- VungTau and Dong Nai province.

The length of the TL in Ba Ria- Vung Tau province is 8.146 km. The length ofthe TL in Dong Nai province is 55.538 km.

Phu My- Song May 500 kV TL is going in areas with plain and low hills. Themain land uses are rubber, cashew, dry crops plantations. Some small water canals arepresented in the Project's areas.

In the first section of the TL, three options were considered.

5.2.1. SECTION FROM G1-G2AOPTION 1

The TL is going along residential area Phu My. Section from GI to G2 is going inthe left hand side of 220 kV Phu My- Long Thanh, Phu My- Ba Ria. After crossingroad, the TL tums left and goes in parallel in the left side of Phu My- Long Thanh 220kV TL till point G2A. The length of this section from Gl to G2A is 7,900 m.



OPTION 2From the starting point GI to G2 , the TL is going in the left side and parallel

with Phu My- Long Thanh, Phu My-Ba Ria 220 kV TLs. This option is veryconvenient for land use planning of Ba Ria- Vung Tau province because the land usewill not be fragmented by ROWs of the proposed TL. The value of land will not bedecreased and socio-economic development of the area will nor be adversely affected.

The length of Option 2 in this section (from GI- G2) is 8,143m. The Option 2is started from distribution yard of Phu My Power Complex. After crossing Phu My-Cai Lay, Phu My- Nha Be, Phu My- Cat Lai 220 kV TLs, the proposed TL tums leftand goes in parallel with Phu My- Long Thanh, Phu My- Ba Ria 220 kV. Theproposed TL is 60 m far from Phu My- Ba Ria TL. The proposed TL is crossingnational road No 51, crossing Phu My- Long Thanh 220 kV, 110 kV TLs and reachesto point GlE. From GIE, the TL is going in the right side and in parallel with theexisting TLs until end of Ba Ria- Vung Tau territory.

OPTION 3This proposed option is quite short, has less effect on residential areas in My

Xuan commune, Tan Thanh district, Ba Ria- Vung Tau province.

The length of this proposed option (from GI to G2A) is 7,013 m. The firstsection is from distribution yard of 500 kV of Phu My Power Complex. The TL iscrossing Phu My- Cai Lay, Phu My- Nha Be and Phu My- Cat Lai 220 kV TLs. Afterthat the TL tums right, reaches to G2, avoids residential area of My Xuan, 1000 m farfrom the existing 220 kV TLs. From G2 point, the proposed TL is same as Option 2.

ENVIRONMENTAL MANAGEMENT PLAN

This Chapter presents the Environmental Management Plan (EMP) developedfor the proposed Project. EMP is an important management tools as well as the

essential and stand alone component of an impact assessment document. It providesthe basis for management system that are associated with a project by demonstratinghow adverse and beneficial environmental as well as socio-economics and healtheffects will be managed in all phases of Project implementation. It therefore describesin specific terms how environmental, health and social commitments developed in theimpact assessment will be implemented.

The objectives of EMP are:- Ensure that activities are carried out in such way to avoid harm to its

employees, contractors and all others that may be affected directly or indirectlyby its operation.

- Ensure that all hazards associated with the job have been properly identified,assessed, barriers established and recovery measures put in place.

- Enforce safe and healthy procedures and practices in all operations, and strivetowards an incident-free workplace.

- Ensure that appropriate training and equipment are provided to enable staffwork in healthy and safe manner.

- Maintain effective communication with all relevant parties.- Ensure that all operations are undertaken with proper regard for the

environment, and strives to reduce environmental risk to a level that is as lowas reasonably practicable.

- Ensure that incident are appropriately investigated and appropriate correctiveactions taken.

- Set clear target to staff involved in the project.

Chapter 8

CONCLUSION AND RECOMMENDATIONS

1. EIA of Phu My- Song May-Tan Dinh 500 kV project has been carried out for over120 km. This was carried out in order to demonstrate that a systematic procedure hasbeen applied in the identification, assessment and evaluation of impacts of theenvironmental aspects of the proposed project on biophysical, social and healthenvironment and in the establishment of mitigation and enhancement measures foradverse and beneficial impacts respectively; and to generate environmental baseline datathat would be sufficient to characterize the ecological, social status of the project areaand enable the issuance of Environmental Permit of the Propose Project by both WB andMinistry of Natural Resources and Environment.

2. The status and sensitivities of the various ecological and socio-economic componentsof the project environment were carefully established and assessed through literatureresearch, field observation, public consultation and literature review.

3. The interactions of the various ecological and socio-economic component of theexisting environment with the known activities of the proposed project were used alongwith other source references to identify, characterize and evaluate the potential andassociated impacts. Mitigation measures were subsequently developed for adverseimpacts based on best industry practice, available technology and PMU, EVNconsideration.

4. Consultation with the affected project communities, regulatory authorities and otherstakeholders have been carried out. The comment, opinion of affected parties, localgovernment were considered and put into this EIA report.

5. EIA report indicates that it would impact positively on economic of Ba Ria- VungTau, Dong Nai and Binh Duong provinces. It also contributes great share onstabilization of nation wide, region wide power network. Important role of the Project isevacuate electricity produced by Phu My power complex to load center in othersouthern provinces.

6. The adverse impacts of the proposed project on land use, vegetation, air, socio-economics and health are localized and can be controlled and ameliorated if therecommended measures are strictly followed. EMP would ensure that the procedures formanaging the adverse impacts of the proposed project as well as the implementation of



the environmental and social commitments made are developed and maintained throughout the project lifecycle. It should therefore form the basis for the actual projectimplementation.

7. The proposed project is considered to be of immense potential and associated benefitsand environmentally friendly. Environmental and social impacts can be managed andcontrolled by the proposed EMP.

8. The cost for implementation of EMP is estimated as 265,100,000 VND (equal to16,800 USD). These costs including (1) cost for hiring third party to monitor air andwater quality during construction site); (2) cost for hiring SMIC; (3) cost for training onEMP implementation; (4) cost for monitoring during operation phase. The cost formitigation measures will be included in estimated cost of the Contractor. Cost forTechnical supervisor of PMU to carry out the additional environmental monitoring willbe includes in running cost of PMU.

9. This ETA report should be read carefully by all parties that are involved in the Project.Project owner through its PMU should integrate EMP into Project implementation planin order to harmonize all of the Project requirements in term of technical issue,economic, social and environment.
