2.2. World Bank Safeguard Policies An environmental and social screening of the subproject was undertaken in line with the

OP 4.01 and it showed that the World Bank’s policies on Environmental Assessment (OP/BP 4.01), and Involuntary Resettlement (OP/BP 4.12) will be triggered for the subproject. The screening has also resulted in categorizing the subproject as a Category B project. In addition, the Bank’s requirements on public consultation and information disclosure will need to be followed.

Environmental Assessment (OP/BP 4.01): Environmental Assessment (EA) is an umbrella policy for the Bank’s safeguard policies.

The overarching objective is to ensure that Bank-financed projects are environmentally sound and sustainable, and that decision-making is improved through appropriate analysis of actions and of their likely environmental impacts. The EA process is intended to identify, avoid and mitigate potential impacts of Bank operations. EA takes into account the natural environment (air, water, and land); human health and safety; social aspects (involuntary resettlement, indigenous peoples, and physical cultural resources); and transboundary and global environmental aspects. EA considers natural and social aspects in an integrated way.

This subproject triggers OP 4.01 because it involves the construction and operation of a high-voltage substation and connecting overhead transmission lines, requiring the identification, mitigation and monitoring of potential adverse environmental and social



impacts. As required by OP 4.01 and the government EA regulation, the subproject has prepared an Environmental Protection Commitment (EPC) and an EMP that meet the Government’s and the World Bank’s safeguards requirements. By the TEP appraisal, the subproject EPC and draft EMP were disclosed locally at the subproject sites and at the Bank’s InfoShop in Washington DC on January 24, 2014 as required by OP 4.01 and the Bank’s policy on access to information.The final subproject final EPC and EMP were disclosed locally at the subproject sites, at the Bank’s InfoShop, and the Vietnam Development Information Center on April 18, 2014.

Involuntary Resettlement (OP/BP 4.12) The Involuntary Resettlement policy seeks to prevent severe long-term hardship,

impoverishment, and environmental damage to the affected peoples during involuntary resettlement. OP 4.12 applies whether or not affected persons must move to another location. The Bank describes all these processes and outcomes as “involuntary resettlement,” or simply resettlement, even when people are not forced to move. Resettlement is involuntary when the government has the right to expropriate land or other assets and when affected people do not have the option to retain the livelihood situation that they have.

This policy is triggered because the subproject it would have impacts involving the temporary and permanent involuntary taking of land and the loss of structures and assets associated with the land for the construction of the substation and the associated connecting line. By appraisal, the subproject has prepared and disclosed a RP locally at the subproject sites and at the Bank’s InfoShop in Washington DC on January 24, 2014. The RP includes the measures to ensure that displaced people are: (i) informed about the options regarding resettlement; (ii) consulted and offered alternative resettlement choices; and (iii) provided with effective compensation and livelihood restoration.

World Bank Group Environmental, Health, and Safety Guidelines World Bank-financed projects should also take into account the World Bank Group

Environmental, Health, and SafetyGuidelines1(known as the "EHS Guidelines"). The EHS Guidelines are technical reference documents with general and industry-specific examples of Good International Industry Practice.

The EHS Guidelines contain the performance levels and measures that are normally acceptable to the World Bank Group and are generally considered to be achievable in new facilities at reasonable costs by existing technology. The environmental assessment process may recommend alternative (higher or lower) levels or measures, which, if acceptable to the World Bank, become project- or site-specific requirements.

This subproject should to be conforming the Environmental, Health, and Safety Guidelines for Electric Power Transmission and Distribution and General EHS Guidelines. 3. SUBPROJECT DESCRIPTION 3.1. Objectives of the Subproject

- Enhancing connection with the 220kV network for the region, ensuring the electricity supply is continuous and safe for the load of the region in any cases.

4. BASIC DATA 4.1. Geographical location and population The subproject has a length of 56.97km including the first part which will be built on Cai Lay district is 9,698m long, and the second with 26,333m length in Cai Be district and the

third with 20,939m length is in Cao Lanh district.



Geographical location and population of the two provinces are as follows: Tien Giang Province

Tien Giang is a coastal province of the Mekong Delta in Southern Vietnam, with a large area belonging to My Tho province earlier. However, the entire area of Tien Giang

province today belonged to My Tho province including Go Cong town in the past. Tien Giang province is in the Mekong River delta and also is the major economic region of

Southern Vietnam, 70 km from Ho Chi Minh City to the south and 90 km from Can Tho city to the north.

Tien Giang province is located in 10°26' N - 106°20' E. It borders Long An province in the north, Dong Thap province in the west, Ben Tre and Vinh Long in the south, Ho Chi Minh City in the north east, the East Sea in the southeast. Tien Giang province has been

planned by the Government as one of the 8 key economic provinces in the southern. Tien Giang province comprises 11 administrative units including 1 city (My Tho), 2

towns (Go Cong, Cai Lay) and 8 districts (Cai Be, Go Cong Dong, Go Cong Tay, Cho Gao, Chau Thanh, Tan Phuoc, Cai Lay, Tan Phu Dong).

Dong Thap Province

Dong Thap province is one of 13 provinces in the the Mekong Delta, it has two large rivers flowing through the province including the Tien river with 114 km length and the Hau river with 30km length. Regarding geographical boundaries, Dong Thap province borders Cambodia with the length of 48.7km in the north, Vinh Long and Can Tho in the south, An Giang Province in the west, Long An and Tien Giang in the east.

Total natural area of Dong Thap is 3,374.08 km2, equipvalent to 8.17% of the Mekong Delta area and 0.99% of the country area. Maximum length from north to south is 96km and the largest width from east to west is 84km.

The population of Dong Thap Province was 1.673 million in 2011, equivalent to 1.95% of the country's population and 9.5% of the Mekong Delta's population.

Dong Thap province is divided into twelve administrative units including: 1 city (Cao Lanh), 2 towns (Sa Dec and Hong Ngu) and 9 districts comprising: Tan Hong, Hong Ngu, Tam Nong, Thanh Binh, Thap Muoi, Cao Lanh, Lap Vo, Lai Vung Chau Thanh. The whole province has 119 communes, 9 towns and 17 wards.

4.2. Topography Tien Giang Province

The topography of Tien Giang Province is flat, with slope lower than 1% and elevation varies from 0 meters to 1.6 meters above sea level, the common elevation is from 0.8m to 1.1m. In general, the whole area's slope direction is not clear, however there are sub-areas with low-lying terrain or hills higher than the general terrain, besides there are many dunes in bow shape with the popular elevation from 0.9 to 1.1m standing out above the surrounding plains.

Land of the province is largely neutral alluvial soil, less acidic along the Tien River accounting for about 53% of the provincial area. Tien Giang province has convenient source



of fresh water which has been put to use for a long time, the paddy fields with high productivity and intensive orchards have been formed in the province; the remaining land area comprises: 19.4% is aluminum soil and 14.6% is saline alluvial soil .

Dong Thap Province

The terrain of Dong Thap Province is relatively flat with common elevation from 1 to 2m above sea level. The topography is divided into two major regions: one in the north of the Tien River and the other in the south of the Tien River.

Dong Thap Province benefits from a large river (the Tien River), channel and spring system, frequently silt-aggraded soil, and permanently fresh and non-saline water source.

4.3. Hydro- meteorological characteristics Tien Giang and Dong Thap provinces are located in the tropical climate zone. In a year,

there are two distinct seasons: rainy season from May to November, dry season from December to April of the following year.

Due to the provinces' topography lying in the Mekong Delta and being crossed by the Tien river and Hau River so they are greatly affected by these two rivers. The hydrologic regime is divided into 2 seasons: exhausted season from December to June of the following year and flood season from July to November.

the period 2006-2012. The economic structure of the province has shifted in a positive direction: reducing the

proportion of agricultural and fishery products and increasing the proportion of services, industry - construction. In 2012, in the GDP, industry - construction accounted for

38.88% and services accounted for 42.1%. Based on the actual data, income per capita increased from 314 USD in 2000 to 724 USD

in 2005 and 2,214 USD in 2012.

Dong Thap province is one of 13 provinces in the the Mekong Delta, it has two large rivers flowing through the province including the Tien river with 114 km length and the Hau river with 30km length. Regarding geographical boundaries, Dong Thap province borders Cambodia with the length of 48.7km in the north, Vinh Long and Can Tho in the south, An Giang Province in the west, Long An and Tien Giang in the east.

Total natural area of Dong Thap is 3,374.08 km2, equipvalent to 8.17% of the Mekong Delta area and 0.99% of the country area. Maximum length from north to south is 96km and the largest width from east to west is 84km.

The population of Dong Thap Province was 1.673 million in 2011, equivalent to 1.95% of the country's population and 9.5% of the Mekong Delta's population.

About administrative regions, Dong Thap province is divided into twelve administrative units including: 1 city (Cao Lanh), 2 towns (Sa Dec and Hong Ngu) and 9 districts comprising: Tan Hong, Hong Ngu, Tam Nong, Thanh Binh, Thap Muoi, Cao Lanh, Lap Vo, Lai Vung Chau Thanh.

period 2006-2012. Rate of Economic growth of GDP averaged 9.7% in 2012. The economic structure of the province has shifted in the right direction: before 2010, agriculture - forestry - fishery reached 41.0%, industry - construction: 27.0%, trade - service: 32.0% ( objectives of 5 year plan, until 2010, the above rates on the order are

40.5%, 28.8%, 30.7%). Based on the actual data, income per capita increased from 406 USD in 2005 to 1,180

USD in 2012.

4.6.2. Society The results of survey and investigation on the socio-economic situation in the communes

in the subproject area in May 2014 are shown as follows: - Average number of persons in a HH 4.30 persons/HH

+ Man 52.32 % + Woman 47.68 %

- Age groups



+ 1 – 17 yrs 12.20 % + 18 – 60 yrs 87.21 %

+ Above 60 yrs 1.59 % - Heads of HH

+ Man 93.50 % + Woman 6.50 %

- Income (annually average income) 85,260,228 VND/HH/year - Average annual expenses 74,400,000 VND/HH/year

Healthcare In every district in the subproject area, there is 1 hospital at the center of district and 1

healthcare station in every commune. The commune healthcare station usually takes care of minor illnesses and childbirth for

women in the commune. District hospitals can cure and treat more serious diseases and do activities to protect public health.

However, health care for workers and the poor has not been guaranteed due to the lack of necessary medical equipment.

Income Main sources of income:

+ Farming 12.12%

+ Wage-earner 53.18%

+ Housewifery 11.35%

+ Others 11.33% It is difficult to specify exactly source of income and income, since many HHs have no

source of main income and many affected households do not have stable sources of income. Many households have multiple sources of income and their income sources vary with fluctuations in harvests and prices of crops.

Average income The socio-economic survey in the subproject area showed that the average income in the

project areas is around 85,260,228 VND/HH/year.

1 Permanent and temporary land acquisition

Medium Short and

Long

- Total permanent land acquisition of the project is land for foundations of the transmission line, this is 25,203 m2. - Land in the ROWs is 704,848 m2. This land will not be acquired but trees higher than 4 m can not planted. - Total temporary land acquisition is 43,000 m2. This land is mainly used for rice and dry crop cultivation.

Medium and mitigable

2 Impact on Subproject affected household

Medium Long term

- Total number of HHs affected by the Project is 712 HHs; - Affected types: land lost for foundation; having house within ROWs; loss of trees and crops, rice; trees will be damaged during cable pulling; change type of trees within ROWs etc. - There are 396 structures within ROWs (including pig sheds, kitchens, warehouses etc.) These structures are not required to be removed, but some modification, repairing are required to meet technical requirements such as roofs and walls need to be made from non-flammable materials; metal parts need to be grounded; structures should not block access to maintain ROWs, high voltage transmission line etc; - No HH needs to be resettled; - Subproject owner will develop and implement Compensation plan.

Medium

3 Loss of vegetation due to land clearance for ROWs

Medium

Long - Areas that transmission line will overpass mainly rice fields, gardens for fruit trees. Besides rice field, number of trees to be cut for acquisition land is 8,282 trees in Tan Uyen district; 1,538 trees in Thuan An town. Names of cut trees are: jackfruit, longan, acerola, tamarind, mango, bamboo, … - These trees mainly have economic value; ecological value of these trees is not high.

Medium




4 Health risk due to chemical hazard

None None - No hazardous chemical will be used for the Subproject. Since 1995, EVN does not allow to buy equipment containing PCB. Therefore there will not be PCBs containing equipment used for the Subproject; - Non of Subproject component is replacement or removal of old equipment so there will be no risk of encountering of PCB equipment; - Subproject will not use chemicals or explosives;

None

5 Impact on historical and cultural properties

None None - There are no historical and cultural resources near and inside the Subproject area

None

6 Health risks caused by Unexploded Ordnance (UXOs)

Medium Short The implementation of the construction of transmission lines in the area of types of UXOs left from the war could lead to serious consequences, dangerous to human life and property of the workers and people local, adversely affect the environmental quality of the area. Before commencing construction activities, the project will deal with specialized military units to perform leakage find mines and explosives in the area all nail column, the total area of demining, animals explosion in the project area is 39,248 m2. Therefore, the risk of accident due to residual mine is low

High

Construction phase

7 Surface water contamination.

Medium Short - The surface water can be more turbid due to soil residues, particles generated from excavation of poles’ foundations. These particles flow into rivers, streams, lakes, ponds. - The subproject crosses the ditchabout 8.5m length (section G6-G7 in Thuan An town). These are source of surface water that might be more turbid in rainy season due to washing out of subproject’s construction materials, excavated soil. - Though the transmission line will cross the ditch but foundations are designed about 70 – 100 m far from ditch shores. Hence soil

Medium and Mitigable




excavation and damming are carried out far from these shores, therefore potential risks on land slides from these shores are not high. At the sites near fishponds, the subproject foundations will construct far from ponds (above 50 m). From the foundation sites to fish ponds are trees, rice fields so potential for debris washed out from subproject excavation to these ponds is also low. - Topography of subproject site is plain with good vegetation cover. - Subproject sites near surface water bodies are also plain so potential for soil erosion, material washing out is low. - Excavation is planned to do in dry season. Excesses soil will be reused to fill in the poles’ foundations. Thus there will be no soil, rock left after the subproject construction. - No tower will be constructed in ditch. - Thus the impact on surface water pollution in the subproject area is assessed as medium and can be mitigated.

8 Noise and vibration

Medium Short - Noise and vibration are caused by: equipment, material transportation, subproject's vehicles, pole's erection and cable's pulling, generators (if there are any) - Most part of the 220 kV line is designed to be far from residential areas as well as the concentration of human activities such as towns and townships. Main part of the transmission line will be far from residential areas. - The main work will be done manually or by small scale machines. Duration of construction for each site at pole’s foundation is short from 2 or 3 days for foundation excavation, 5 days for pouring concrete, 2 or 3 days for cable pulling. Noise and vibration (if there is any) will be caused only during very short period of time in each foundation position; - Owing to these mentioned reasons, the noise and vibration impact caused by the subproject is considered as medium.
