1. INTRODUCTION

Subproject “220kV Quang Ngai - Quy Nhon (Phuoc An) transmission line” is one

of the subprojects that will be implemented in Phase 1 of Transmission Effeciency

Projects (TEP) funded by the World Bank.

Investment of the subproject “220kV Quang Ngai - Quy Nhon (Phuoc An)

transmission line” is fully suitable with the National Power Development Master Plan in

the phase of 2011 - 2020 with the vision to 2030 at the Decision No. 1208/QD-TTg dated

July 21st, 2011 approved by the Prime Minister.

Activities of the subprojects include:

+ Construct 220kV double-circuit Quang Ngai - Quy Nhon transmission line, in

which one circuit suspended in advance in 2016. The TL has 139,888m in length, and its

ROW is 21.2m in width.

+ Construct one 220kV outgoing bay at the 220kV Quang Ngai substation.

Those activities may cause negative impacts to environment and community during

the pre-construction, construction and operation phases.

In order to realize and minimize potential negative impacts during the process of

project implementation and comply with the Environment Assessment Policy of the

World Bank (OP/BP 4.01), Environmental management plan (EMP) of the subproject has

been prepared suitable with the guidelines in the Environment and Society Management

Framework of the TEP. This EMP consists of description of the subproject, legal and

policy frameworks, environmental national technical regulations and standards, potential

negative impacts, mitigation measures proposed to be carried out in the phases of the pre-

construction, construction and operation, implementation arrangements. Mitigation

measures proposed in the EMP will be incorporated in bidding documents and contracts

and attached to environment supervision during the implementation process.

According to the regulations of the GOV, the subproject has prepared an

Environmental impact assessment (EIA) report. In April 2014, the EIA report of the

subproject was submitted to the Ministry of Natural Resources and Environment for

appraisal and approval. It has been approved at the Decision No.2063/QD-BTNMT dated

Environmental and social screening for the subproject was carried out in compliance

with and it showed that the WB’s policies on Environmental Assessment (OP 4.01) and

Forest (OP/OB 4.36) are necessary to be conducted for this Subproject.

- Environmental Assessment (OP/BP- 4.01): implementation of the subproject will

construct 220kV Quang Ngai - Quy Nhon double-circuit transmission line with one

circuit installed in advance in the year of 2016 and construct one 220kV feeder bay at the

220kV Quang Ngai substation. Hence, the Policy OP/BP-4.01 will be applied to

guarantee substainability for the project investment and socio-environment aspects;

supply information of potential socio-environmental impacts of the subproject for

decision makers. Subproject is screened of environment and society in compliance with

the criteria in the OP 4.01 and categorized B for environment aspect; Environmental

safety tool that the subproject shall prepare is Environmental Management Plan.

- Forests Policy (OP/BP 4.36) is intended to support sustainable and conservation-

oriented forest management. The Bank helps borrowers harness the potential of forests to

reduce poverty in a sustainable manner, integrate forests into sustainable economic

development, and protect vital local and global environmental services and values of

forests. Local people, the private sector and interest groups in the affected forest area

should be consulted.

The policy is triggered considering that some subprojects may involve acquisition of

forest land for maintaining ROW of the power transmission lines. These activities may

have the potential to have adverse impacts on the rights and welfare of local people and

their level of dependence upon low quality natural forests and plantation forests. Impacts

on forests and associated mitigation measures will be included in the subproject EIA and

EMP.

The project will not fund any subproject (1) that would involve significant conversion or

degradation of critical forest areas or other natural habitats; (2) that contravenes

applicable international environmental agreements; and (3) that involves any conversion

or degradation of critical natural habitats, including adjacent or downstream critical

natural habitats

- Involuntary resettlement: implementation of the subproject will acquire land

permanently and temporarily to construct tower foundations of the T/L. Hence, when



applying this policy, objectives of this policy is to prevent from serious, long-term

difficulties, hunger and poverty and environment damages for the affected people during

the involuntary resettlement process. A resettlement plan for the subproject will be

prepared to reach the objectives of this policy.

b) Power post

Construction volume of power posts are:

- Volume of form steel: 7,044.16 tons

- Anchor bolt: 99.28 tons

c) Conductor

Total length of conductor types used for the subproject:

- Conductor ACSR-330: 254.1 km.

- Conductor ACSR-400: 165.87 km.

d) Lightning conductor and optical fibre

+ Lightning conductor GSW-70: 139.99 km.

+ Lightning conductor combined with optical fibre OPGW-70: 141.69 km.

e) Insulator and conductor accessories

- Insulator: At present, in Vietnam, there are two types of insulators of composite

and ceramic or glass, each type has typical advantages and disadvantages, so insulator for

the 220kV Quang Ngai- Quy Nhon (Phuoc An) transmission line will be selected through

competitive bidding.

- Accessories for suspending conductor: Accessories for suspending conductor and

lightning conductor will be suitable with conductor size and ensure conditions of

corrosion and durability reserve factor as regulations.

Accessories for suspending conductor are expected to be imported in sync with

insulator though competitive bidding. Types of cable rings, hangers, couplings shall have

breaking load suitable with insulator. Insulator strings are designed to have

electromagnetic balancing ring and arcing horn to improve voltage difference between

bowls of insulator strings and avoid corona effect in the surface of insulator string.

+ Bear lock of conductor and lightning conductor uses fixed brace bolt lock.

+ Conductor and lightning conductor stay locks use clamp stay lock.



+ Bear and stay lock of lightning conductor combined with optical fibre use

dedicated locks for optical fibre.

f) Compensated damper suspend on insulation string

Because the T/L goes through mountainous topographical area, difference of

elevation between tower positions is rather large, some positions of columnar posts will

reduce gravity tower distance, cause insulating string will be deflected over permission

limit, and not guarantee required distance on tower.

To compensate the reduction of gravity tower distance, solution is to suspend

compensated damper on support insulation string. Weight of compensated damper is

calculated for each position based on allowable insulation string deflection angle.

Types of compensated damper used on the line are TB-100, TB-200, TB-300, TB-

400, corresponding weight are 100kg, 200kg, 300kg, 400kg.

g) Earthing

All towers in the transmission line will be grounded suitable with resistivity of each

area which the T/L crosses over, value of grounded resistivity shall meet standard and

regulations.

Earthing on the 220kV transmission line will use ray-type earthing: TD4x30;

TD4x40 and ray- rod combination earthing: TD4x20-16; TD4x30-24; TD4x40-28.

- Ray-type earthing TD4x30 : consists of 4 rays grounded by round steel with

dimension of 12mm, length of each ray is 30m.

- Ray-type earthing TD4x40 : consists of 4 rays grounded by round steel with

dimension of 12mm, length of each ray is 40m.

- Ray-rod combination type earthing TD4x20-16 : consists of 4 rays grounded by

round steel with dimension of 12mm, length of each ray is 20m. Each ray connected with

4 steel rod Lx63x63x6 length of 2,5m.

4.3 Climate

The transmission line locates on Quang Ngai and Binh Dinh provinces which have

general characteristics of South-East tropical monsoon climate, in addition, climate and

weather regime of the route area also have characteristics of coastal Central region with

typical characteristics as below:

Because of wind stop effect of Truong Son mountain range which is closed to the

sea at Hai Van mountain pass, tropical air at the south of Hai Van pass denature fully,

therefore it is less cold in winter, the lowest monthly average temperature is 18.8oC

(January), the absolute lowest air temperature is 10.2oC, average temperature difference

between the hottest and coldest months is about 6-7oC.

Rainy season starts from August and ends on January, the highest rainfall months

are October and November with average rainfall of 500-600 mm. Total rainfall in rainy

season account for 80-90% total annual rainfall, dry season is from February to July,

account for 10-20% total annual rainfall.

Remarkable weather phenomena in this region are storm, thunder and hot and dry

westerly wind. Storm season lasts from September to November, annualy there are 1-2

storms in this region with strong effects.

Thunder is little, thunder season coincide with summer monsoon, from April to

October, an average number of thundering days are 50-80.

Hot and dry westerly wind in the first half of summer, from April to August which is

rather strong is the reason of extreme air temperature over 40oC and low humidity

under 25-30%.

* Wind:

+ Prevailing wind direction

From October to March (winter monsoon): N, NW (North, North West)

From April to September (summer monsoon): E, W, SE (East, West, South

East).

+ Average wind speed: from1.6 m/s

+ Wind Pressure: According to wind pressure division map in National Technical

Regulation of natural condition data in construction QCVN 02:2009/BXD, wind pressure in

the route area is defined as below:

Table 10: Standard wind pressure with repetition cycle of wind in ten years and in 20

* Communes in the subproject area:



Agroforestry industry is a major contribution to the economy of communes where the

220kV Quang Ngai - Quy Nhon (Phuoc An) line goes through, accounting for 70-75% of

GDP. In the subproject area, agricultural crops are mainly rice and vegetables (beans,

peanuts, sesame, melon,...); forestry crops are mainly acacia, eucalyptus (paper material).

In addition to farming, farmers in the region also focuses on development of

livestock (buffaloes, cows,...) for traction, and poultry to provide nutrients and increase

revenue.

The area of agricultural land in the communes in 2012 is presented in Table 10:

b) Industry:

* Quang Ngai province:

The value of industrial production, service, and trade is estimated at 120,000 billion

VND, accounting for 102% of the target, the value of port cargo throughput is estimated at

12 million tons, reaching 160% of the plan. Creating new jobs for 600 workers, reaching

60% of the plan

In Quang Ngai industrial zones, there have been 80 projects attracted with a total

registered capital of nearly 5,000 billions VND, of which 44 projects are now actively

operational, creating frequent jobs for more than 8,000 workers

* Binh Dinh province:

The industrial production value is estimated at 8,056.2 billion (1994 constant price),

accounting for 93% of the plan, but increasing 8.1% compared with 2011; in which, most

economic sectors grow, such as the state enterprise sector increased by 12.7%; non-state

enterprises sector increased by 6.2%; individual household sector increased by 12.6%;

foreign investment sector increased by 14.2% compared with 2011. In 30 major industrial

products of the province, there are 21 products, of which theirs production ouput increased

over the same phase. Some other products increased significantly such as: titanium ore

increased by 36.7%, titanium ore concentrate increased by 23.4%, bottled beer by 23.4%,

fish fillet and chilled fresh fish increased by 21.5%, cattle feed increased by 16%, solution

of serum protein increased by 22.4%. The products that decrease are: Refined Standar sugar,

stone exploited for construction, tiles etc.



Overall, the value of industrial production continued to grow despite not reaching its

target which represents a great effort by all levels and branches of goverment in directing and

resolving difficulties for enterprises. Regarding enterprises, they have also attempted to

overcome difficulties in the difficult conditions of the domestic economy. In 2012, the

enterprises of garment industry had organized production and business activities efficiently,

and had signed many orders directly with foreign countries like America, Japan, Korea,

Canada, etc. contributing to improve exports and stablize livelihood, employment for

workers. However, there were still many enterprises processing product, which were the

strength of the province, such as seafood processing and exporting, wood, rocks, minerals and

titanium, etc. were moderately active due to lack of raw materials or price input is too high,

narrow markets, low competitiveness.

* Communes in the subproject area:

The communes in the subproject area are rural agricultural communes, therefore, the

industry virtually undeveloped. There are 2 communes: Pho Phong commune - Duc Pho

district - Quang Ngai province and Nhon Hoa Ward - An Nhon town - Binh Dinh Province

that had industrial zone. These industrial zones also had created works for local labors. The

major industries in the industrial zone were wood processing, granite, cattle feed processing,

garment.

c) People’s income

According to the socio-economic survey of the mission team of the PECC4 in March

2014, most of the income of households where the route passes through mainly came from

agriculture. Per capita income was from 450,000-550,000 VND/person/month, especially

there were households that only reached 300,000 VND/person/month

d) Transportation

The subproject mainly passes through communes with flat terrain (plain), therefore

the transportation in the area is well-developed. In addition to the Highway No. 1A,

Highway No. 24, Highway No. 19, transport system of provincial road, and inter-communal

road are also well-developed as well, which meet the needs of communication between the

subproject area and other areas

100% inter-communal roads are asphalted; inter-village roads are expanded,

concreted or bricked in accordance to the program of the state and people working together.

4.5.2 Public Health:

100% communes in the subproject area have medical personnel and clinics.

However, some clinics still lack of facilities, equipment and manpower, but generally has

met the medical needs of people.



4.5.3 Education:

100% communes in the subproject area have primary schools, junior secondary

schools. 100% communes in the subproject area has eliminated illiteracy.

The social situation of the communes in the recent years was relatively stable

4.6 Ecology.

According to the result of field survey conducted by PECC4 in March and April

2014, the entire 220kV Quang Ngai - Qui Nhon (Phuoc An) transmission line goes mainly

through flat land, paddy fields, crops; plantations of acacia, eucalyptus, Azadizacta indica

tree (raw material for paper production) of local people; a small portion of the route goes

through natural forests with poor resources that are assigned to local people to take care and

protect. The route is divided into the following major sections:

+ Sections: G11-G16, G16-G24, G24-G35, G39-G41, G60-G62 mainly go over

hillsides, low mountains, fragmented terrains with average slope of 1500-200

0, terrain altitude

varying from 20-200m. Vegetation cover is mainly acacia plantations (paper material) and a

few Ib, Ic, IIB productive natural forests. The planted productive forest area (mostly plantations

of acacia from 1-8 years old) is in the ROW. Productive forest area has been assigned to people

by the CPCs (FLA format) to take care and protect. For protective forest, the route has 11,700m

in length going through protective forest and 850m in length going through natural protective

forest that is under management of Hoai Nhon protective forest management board (managing

from G16 to G24) and Phu My protective forest management board (managing from G24 -

G35).

+ The remaining sections pass through flat terrain with mostly rice fields and crops. A

few sectios cut through some small decentralized residential areas. Vegetation cover on these

route sections are mainly rice and vegetables (peas, corn, sugar cane,...), fruit trees (of which

sections cutting through residential areas).

a) Vegetation

Overall, the vegetation cover in the line route area is poor due to strong impact

caused by human

* Natural flora:

Some sections of the line in the G9-G18, G33-G35, G39-G42 goes through terrain

which is mostly hills, low mountains (300m in altitude), with an average slope of 100-30

0,

and is not much difficult when approaching. On the other hand, traffic in the subproject

areas is developed in natural forest which have been strongly affected by human

- The total length of the route going through the natural forest land is 9,576 m. Based

on the assessment report on environmental impact of the subproject, the followings have

been identified:



+ 8,726m section is low-value forest with no reserves and grassland, shrub which

was assigned to local people to reforest and take care

The forest status is mostly low-value secondary forest with no existed valuable large

trees, and with vacant land or bushes. The species in this area are less diversed in

composition and are species with wide ecological amplitude, and distributed in the

surrounding areas such as bamboo species, Fagaceae, Meliaceae, Clusiaceae, Annonaceae,

Melastomaceae, Urticaceae, Araceae, etc.

Forest land is scattered in the subproject area into small parts mixed with agricultural

land and acacia plantations. The common species in this type of flora are walnut

(Juglandaceae), areca (Asteraceae), grass species of Poaceae familia, etc.

There are 850m of G34 - G35 section at Ho Voi lake’s upstream having natural forest

with IIB status, which is a form of restored young forest that has the reserves of 30m3/ha

and was assigned to Phu My Protective forest Management Board for protection purpose.

* Artificial vegetation:

Rice fields, vegetable gardens

They are distributed in areas with flat terrain, river, and canals; areas that are near the

residential area; areas that have good soil with little floods, and being favorable of water in

dry season; and areas with high plant restructuring. This part of vegetation cover accounts

for the majority of land in the ROW.

Mixed garden, fruit trees, cashew trees

This landscape appears in the residential areas. Mixed gardens provide food, fruit,

reduction in temperature and air purification, keeping the balance of the ecosystem, shelters

for birds, and reptiles which are the natural enemies of many orchard pests for, etc. Mixed

gardens offer fruits like banana, guava, orange, plum, coconut,... and provide a portion of

fuel daily.

Forest plantation

- Forest plantation is mainly hybrid acacia plantations (paper materials) that are on the

hillside, sloping land allocated for the local households.

- Protective forest plantations are mainly hybrid acacia plantations which are under the

management of two units: Hoai Nhon Protective forest Management Board and Phu My

Protective forest Management Board.

- Acacia, Azadizacta indica trees have average height of 5-12m, average diameter of

100-700mm, and density of 0.11trees / m2.

- Agarwood has the average height of 1-4m, average diameter of 30-70mm, density of

0.25 plants/m2.



- In the ROW, there are 557 hopea odorata trees with a diameter of 5-15cm, height of

7-15m which belongs to Phu My Protective forest Management Board
