2.2. World Bank Safeguard Policy

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 EIA and an

EMP that meet the Government’s and the World Bank’s safeguards requirements. By the TEP

appraisal, the subproject draft EIA and EMP were disclosed locally at the subproject sites and

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 EIA and EMP were disclosed locally at the

subproject sites, at the Bank’s InfoShop, and that the Vietnam Development Information

Center on January 24, 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 draft RP locally at the subproject sites

and 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. The final EIA and EMP were

disclosed locally at the subproject sites, at the Bank’s InfoShop, and that the Vietnam

Development Information Center on January 24, 2014.

significant transportation advantages facilitating good and trade exchange between Hanoi and

the west provinces. The district administratively borders Phuc Tho district to the north;

Chuong My district to the south, Hoai Duc district and Ha Dong urban district to the east; and

Luong Son, Ky Son district on the west.

4.2. Topography

Topographical condition in area where substation will be constructed comprises mainly paddy

fields, pond, channel, demarcation between population centers, limits between subsidiary

crops, and limits of graveyard.

This area is distributed mainly with trees, subsidiary crops owned by local resident.

Vegetation, subsidiary and tree are distributed as below:

Subsidiary crop land : 15%

Paddy land : 85%

Generally the area is classified as topographical grade III

4.3. Hydro- meteorological characteristics

Geology

On paddy field area and subsidiary crop field, topography of the deposited delta has rather flat

surface with unremarkable different in height. Rock and soil structure creates this topography

are mainly: hard plastic clay, soft plastic clay, semi soft plastic clay, semi plastic sand which

are originated from blend river, ocean deposits (amQ)

Meteorology

On the project site, from May to October, the climate is hot and humid, the average

temperature is 27.7 oC. From November to April the next year, the cold climate with an

average temperature of 19.9 oC. Absolute highest temperature measured at the meteorological

station in Ha Dong was 40oC, appeared on 5/7/2010. Absolute lowest temperature measured

was 5.9 ° C on 26/01/2005.

The average humidity of the project area from 2002 to 2011 was 84%.

Total average sunlight hours measured in 10 years (2002-2011) was 1325.9 hours/year.

Sunlight mode is closely related to the mode of radiation and cloud status. From December to

April the sky is cloudy so that the sunlight hours is at least of a year, only 63.6 hours/month.

In May, the weather is warmer so that the number increases to 144 hours /month.

On the project site, winter wind is prevailing at the northwest and north directions, summer

wind is prevailing at the South East and North Northwestern directions.

_________________________________________________________________

______________


22

Rainstorm: During the hot season (from August to October), there are a certain number of

tropical depressions and typhoons forming offshore Philippines going through the East China

Sea then landing on the Northern Plain towards the West cause of heavy rains and strong

winds.

Hydrology

The 2 rivers flowing through the district are Day river and Tich river. The hydrological

mode of the district depends on Red River, Day river and Tich river and many other ponds

and lakes.

- Underground water: Underground water level stabilized at a depth of 0.0-1.2 m. Water

penetration is weak (Ia) according to TCVN 3994-85

- Surface water: the planned site building the substation is located on alluvial plains right

bank of Day river, there are many ponds and lakes. During the time of landform surveying,

the major substation area were flooded. Water supply to Day river and ponds, lakes, rice

fields is mainly the upstream water, rain water and irrigation water inland.. The level river

water usually high on rainy season. The water penetration is weak at the substation area

according to TCVN 3994-85.

- Surveying work about water supply for the substation: the planned site building the

substation is about 400m away from the residental area of Yen Noi village, Dong Quang

commune, Quoc Oai district, Hanoi city. Currently, local people use water taking from public

deep wells. Water purchase contract could serve the needs of water at the substation in Dong

Quang commune.

On the basis of the statistics data for 10 years (2002-2011) of the substation the water level

of Day river in the flood season (VI-X) is quite high. Monthly avarage water level for many

years in the flood months are greater than 110cm. The highest average water level is reached

211cm in August. Annual average water level at the project area is 105cm.

4.4. Land use

Xã Đồng Quang có diện tích tự nhiên 1.080,89ha, trong đó có 601,39ha đất nông nghiệp và

nuôi trồng thủy sản. Bên cạnh đó, đất phi nông nghiệp của xã chiếm 26,9% bao gồm 92,1ha

đất ở; 108,88ha đất giành cho giao thông; 85,09ha đất thủy lợi và 2070m2 phục vụ vệ sinh

môi trường.

4.5. Environmental baseline data

4.5.1. Air

Dust density

Suspended dust is one of the important criteria in the inspection evaluating impact of the

production areas on the environment. According QCVN 05:2009/ BTNMT, dust density of 300

μg/m3 in ambient air is allowed. Under this regulation, at all supervisory positions in the

construction area of 500 kV and 220 kV Tay Ha Noi substation (expected) the dust density are

very low and within the permitted value. Dust content in the same place in the afternoon is more

than that of the morning due to cool weather, high air humidity and light winds cause lower dust

content

The density of toxic gases

SO2 emission: According to QCVN 05:2009/ BTNMT, the density of SO2 in the ambient air of

300 μg/m3 is allowed in the project area, the gas density at all monitoring points are very low and

within permissible standards, from 51 to 68 μg/m3, the highest is at K5 position - on the dam of

Day River in the afternoon, influenced by traffic activities because there are many vehicles

involved.


_________________________________________________________________

______________


23

NO2 emission: According to QCVN 05:2009/BTNMT, the NO2 density in the atmosphere is

allowed around 200 μg/m3. The analysis results showed that the density of NO2 in the surveying

area is much smaller than the allowable value. NOx density ranges from 42 to 54 μg/m3. The

small density of exhausted gases is small due to mainly agricultural activities in the surveying

area.

CO emission: According to QCVN 05:2009/BTNMT, the CO density in the air allowed is around

30,000 μg/m3, generally carbon oxide emissions in the project area and in the surrounding area

are permitted. The density of carbon oxide in the areas ranges from 1.745 to 1.905 mg/m3

Noise

Monitoring results showed that noise level Leq in most of the measuring positions is lower than

the allowed value in QCVN 26:2010/BTNMT. Noise levels in the measuring points on roads are

higher than that in the substation area, measured noise levels in the afternoon is higher than in the

morning, noon and night due to many life activities of local people at this time.

Vibration

Vibration unit is vibration acceleration (m/s2). Measuring results showed that the vibration

levels at most of points of the project area have the same value of zero (not detected).

4.5.2. Water condition

Quality of surface water environment

The analysis results indicated that the quality of irrigation water used for irrigation purposes for

farming (NM1) has most of the parameters following QCVN 08:2008/BTNMT applied to the

column B1 (used for irrigation purposes) but at a higher threshold. Some of nutrition figures as

NH4, NO3-, PO43- or nutrition figures such as TSS, BOD5 began exceeding permissible

standards, demonstrated the quality of this irrigation water has been contaminated at the low level

except for the heavy metal figures.

The water quality of Day River has most of parameters met the standard QCVN 08:2008/BTNMT

applied to the column B1 (used for irrigation purposes).

Quality of underground water environment

Generally underground water quality in the project area is permitted according to QCVN

09:2008/BTNMT. Some figures such as COD, ammonia, heavy metals (Asen, lead, iron)

approximate allowable values, especially the figure Coliform of underground water samples NN1

has the concentration of 3 MPN/100 ml, reaching a the highest threshold as QCVN

09:2008/BTNMT. Therefore, in case exploiting groundwater project for domestic purposes

should consider to that two parameters.

4.5.3. Soil condition

Content of metal Asen, Cd, Zn, Cu, Pb, Hg in soil, indicates the accumulation of heavy metals in

agricultural land. The analytical results of the heavy metal content for all examined samples are

much smaller as the standard QCVN 03:2008/BTNMT. This showed the soil samples of the

surveyed area are not contaminated heavy metals and relatively safe for the development of

production, the cultivation of food crops, vegetable.

Electro-magnetic condition

Survey results at measurement points are within the range of 1 kV/m, in the permitted value (eight

hours continuously), that less than value 5kV/m as specified.

For the strength of the magnetic field, the measured values are very smaller in comparison with

the standard and the magnetic sources in the area are almost undetectable.

4.6. Socio-economic status of the project area

Dong Quang commune has 3,330 households with the population of 13,759, including 7,880

persons at the working age, accounting for 57.59% of the population. The natural growth rate

sensitive area, cultural property, historical monument, temple and pagoda in the project area.

V. ENVIRONMENTAL IMPACT ASSESSMENT

The subproject would contribute to meeting the demand load and power safety in Hanoi city

and thereby bring about significant socioeconomic benefit. Apart from such benefits, the

subproject may also result in environmental and socioeconomic impacts which are adverse to

the local conditions.

The environmental screening of the subproject indincates that it is eligible for financing

considering that the subproject would not involve possible high risk and would not create

potential adverse impacts on (a) critical natural habitats and/or protected area including

proposed protected areas; (b) loss or damage to cultural property, including sites having

archeological (prehistoric), paleontological, historical, religious, cultural and unique natural

values, graves and graveyards; (c) water regime, particularly water flow and water quality;

and (d) local traffic.

The implementation of the subproject would mainly cause land acquisition, increased dust

generation, air pollution, domestic waste, and health and safety issues due to construction

activites and electrical magnetic field. However, these impacts are not significant, temporary,

localized impacts with available mitigation measures. Only OP 4.01 and OP 4.12 are triggered

for this subproject.

The potential negative impacts of the subproject are identified in table below and could be

minimized by applying the proposed mitigation measures developed for the subproject which

is described in the next section.

significant due to amount of waste gases is not large and the concentration

of emissive sources is low.

+ Impact of dust: dust generated from digging and leveling operations, transport

operations from the equipment and machinery. The area around substation is

mainly paddy-field and distance from residential areas to position

of project at least 150m. The project only affect the people who

live along the route of road transporting building materials from the provincial

road 80 to substation. Therefore, this impact is considered to be small

and significantly only in the dry season, it is temporary and will terminate at

the end of the construction activities.

6 Noise and vibration

caused by vehicles and

machinery

Small Short-tern In the constructive process, transport vehicles and machinery can cause noise and vibration

affect households along the roads and at the constructive location. However, this effect is

small and will expire after constructive period because of the project applied the mitigative

measures and only occur during the construction.

7 Pollution of soil, air and

water due to leakage of

oil from machinery,

construction equipment

Medium Short-tern - Leaking oil from machineries, transport equiments can affect the environmental quality of

land and water, especially during the rainy season, the leaking oil can spread under water

overflow affecting quality of soil and water at the surrounding area...

- Transformer oil or oil having PCBs might also be leakage to the environment due to

accidents. However, oil having PCBs to be used at substation are prohibited by the national

regulation.

- The operation of the substation will use some chemicals available in such equipment as

battery, insulating oil, grease oil and etc., but in small quantities.

8 Inpact on quality of the

environment from the

disposal of waste.

Medium Short-tern

to average

These wastes include construction and household waste that can cause adverse impacts on

environmental quality. During the process of project construction, all types of construction

waste must be planed to collect, sale and proper disposal (leveling).

For household waste arising from the operation of the workers will be collected and

disposed of in the proper place. However, should set up a appropriate monitoring plan to

ensure the waste is collected and handled according to regulations.

9 Impact on health and

safety from

construction camps,

material storage

Medium Short-tern

to average

The project is needed to have some storages (closed and open) containing construction

materials for substation and must construct workers' camp for the workers can take a rest at

there

The camps and warehouses containing materials can cause risks to the safety and health of

the local population and construction workers due to the stored material and equipments is

unsafe, this can arise a conflict between the workers and the local population.

Workers will be recruited from local population, the camps will have mobile toilets and

equipment, construction materials have been designed layout at the right place, security

surrounded. So conflict with local population and impact on the health and safety from the

camps and the storage is very small degree.

10 Conflicts arise between

construction workers

and local people

Small Short-tern The focus of large amounts of construction workers (maximum 70 people) will arise a

conflict between the workers and the local population. However, the main contractor will

hire local workers for the suitable jobs so the impact of this is minor and can be mitigated.

12 Impact to cause damage

the system of local

roads because of

construction activities

and transportation of

building materials

Medium Short-tern The position of project is located nearly the inter-commune and inter-hamlet roads, the roads

covered with thick plastic for convenient transportation of building materials. Moreover, the

scope of the project are relatively small, the level of activity of the transport is not high, thus

damaging impact on local roads due to the construction of the project is not significant.

Construction contractors will be working with local authorities in the use of local roads to

transport equipments and materials.

THE PERIOD OF OPERATION

13 Effect of excessive

electromagnetic

intensity

Medium Long-

term

If not properly designed and constructed the substation and

the connection lines would have adverse impact on worker and

community health. Calculation results and actual test in the existing 220kV substation

and transmission line show that the intensity of the electromagnetic field is much lower than

the permissible level 5kV/m. Therefor, it does not affect health of human. 220kV Tay Ha

Noi substation is designed to comply with the codes and safety regulations, safety rules.

While working will also be strictly applied to the operational staff to ensure electromagnetic

safety.

and the risk of electric

shock.

Medium Long-

term

In the period of project design, the safety measures have been implemented. However,

electric shock and effect on safety of local residents and workers who operate the sunstation

still has the possibility of failure to comply with security measures.

17 The risk of fire due to

oil leak Medium Long-

term

The project is likely to increase the risk of fire due to leakage of transformer’s oil or the

explosion of transformer. However, the risk of fire is minimized by the substation was

equipped with oil collecting pit to contain all the transformer’s oil when the transformer is

damaged, the fire fighting equipment as automatic fire alarm system, water sprayer...

18 Pollution caused by

leaking oil and toxic

chemicals

Medium Long-

term

The oil leaking from the transformers can adversely impact on environmental quality of soil,

water, air . To prevent adverse impacts on the quality of the environment by oil leakage, the

oil collecting pit was designed to recover all the oil leaks due to the breakdown of the

transformer. The oil collecting pit is construced by reinforced concrete placed

monolithically with transformer’s foundation and anti-fire wall’s foundation and higher than

0.3m in comparison with the substation’s surface, the pit bottom is created slope I = 0.5 % in

the direction of the oil conllection tube . The breakdown oil tank is buit in the ground by

reinforced concrete, cement plaster, the tank’s cover is higher than 0.15 m in comparison

with the substation’s surface. The breakdown oil tank is arranged in convenient location for

the collection of transformer oil . The tank’s capacity is V = 100m3 to ensure collecting 100

% of oil go out of the transformes when there is a problem . The breakdown oil (if any) will

be collected in oil collecting pit and flow under the oil drain pipe to the breakdown oil tank

located in the substation.

Required insulating oil of transformers is not included PCBs other toxic chemicals

19 Noise from process of

substation operation Small Long-

term

Transformers are manufactured in accordance with the order prescribed noise levels , the

noise shall not exceed 70dBA at a distance of 3m and installed properly technical

requirement to restrict noise. Since the substations located in industrial zones so the impact

of noise is negligible.

20 Impact of domestic

wastewater and solid

waste of operation staff

Small long-term During the operational period, the project does not generate hazardous waste. For municipal

waste arising from the operation of the substation's operators, the project was designed to

build a septic tank under the toilet to treat before release, the solid waste is collected and

disposed in according to locally common system of garbage collection. Therefore, the impact


_______________________________________________________________________________


30


on environmental quality due to the discharge of wastes considered negligible.

21 The breakdown of grid

incidents, occupational

accident, in the process

of operation

management.

Medium long-term During the process of management, operation, repair and maintenance works, the breakdown

of grid incidents and accidents can occur if the operator and maintenance personnel do not

comply with safety rules and operation.
