IV. Summary of natural and environmental conditions of the project site

Natural and environmental conditions

Preliminary description of natural and environmental conditions of the project site (e.g.

county of the project site) provincial project, scope of project. Provide important information

about environment, focus on terrain, status of land use, surface water environment,

underground water, air quality (short summary of information from EIS or project

commitment to implement established environmental protection)

Meteorology - Climate. Data provided by Vinh Yen Hydro-Meteorological Station (from

2007 to 2010), indicated that Vinh Phuc Province and project site is under tropical monsoon

climate, with typical hot and humid weather, and divided into two obvious seasons: rain and

dry season. The rain seaon ranges from April to September, and dry season from October to

March of the next year.

Terrain. Vinh Yen City has a typical midland terrain, with altitude of 10-50m over sea level.

Area of highest altitude is mountainous area northeast of Khai Quang District and lowest is


_______________________________________________________________________________


NPC

Dam Vac. Overall, the terrain tend to incline in northeast – southwest direction and is clearly

divided into 3 areas:

- Low mountain: gathered in north of Dinh Trung and east of Khai Quang counties, with

absolute altitude ranging from 50-260 m; this region has many high noncontinuous hills and

low mountains composed of mica schist, arkose and rhyolite.

- Low hill and antique silt steps: altitude of 10-50 m, lightly inclined and corrugated in south –

southwest direction, alternately inserted with small steps and slots; it includes the whole

central city and ends at hill areas of Mau Lam, Mau Thong hamlets of Khai Quang district.

- Delta and swamp: developed on neo silt deposit in the south, including residential quarters

and farmland of Khai Quang district and Thanh Tru commune; the terrain is lightly

corrugated, with altitude of 7.0-8.0 m, alternately inserted with pond, lake, rammer with good

free air.

Hydrologic conditions. The city has many lakes of different sizes, distributed evenly and are

important in regulating and reserving water. Vinh Yen City is within the basin of Ca Lo and

Pho Day rivers, but river concentration is low. Slow drainage caused overall waterclogged in

low areas. In dry season, water level drops dramatically, causing difficulties water usage for

utility and production.

Air environment. Observation and sampling resuls indicated that, in comparison with QCVN

05:2009/BTNMT regarding air quality of surrounding areas, all observed air is within limit of

standardized environment quality.

Surface water. Observation results indicated bound concentration of metals is lower than

standardized level allowed by QCVN 08:2008/BTNMT regarding surface water quality.

Analysis results of surface water environment quality indicated that surface water status in

project site could still receive treated exhaust. COD, BOD5 and NH4+ parameters indicated

signs of pollution, which is believed to be reserved from agricultural production activities.

Underground water. Survey results of underground water samples in project site indicated

that most concentrations of analyzed samples were lower than standardized levels allowed by

QCVN 09: 2008/BTNMT regarding underground water quality.

Soil. Observation and sampling at project site indicated that concentration of substances was

within allowed standards for industrial land standards. Soil environment status of project site

indicated that all criteria for heavy metals were within allowed limit of QCVN 03:

2008/BTNMT

Cultural and historical sites. At project site there was no famous cultural or historical relic

that was rated or complied with village custom.

V. Environmental impact assessment

Screening Question Yes No Remarks

1. Project's sitting:

Is the Project site adjacent to or within

any of the following environmental

sensitive areas?

No impact

Cultural heritage site X


_______________________________________________________________________________


NPC

Protected areas such as National

Parks, Nature Reserves,

Bioconservation areas, bird

yards, mangrove forest etc.

X

Wetlands X

Forests X

Estuaries X

Buffer zone of Protected areas X

Rivers and reservoirs

X

Canals and irrigation system X The existing ground elevation of station

location is 7.77- 8m and it will be

heightened to the elevation of 9.2

equivalent to NH2 bypass road elevation.

Such elevation heightening will result in a

difference of more than 1m which likely

causes flooding around the transformer

station area.

The terrain at the station is relatively flat

so surface water sources are mainly rain

water and irrigation water of interior field.

The proposed construction site of the

station does not encounter any river,

chanel, lake and pond so this does not

affect the water source.

.

Agricultural land X

2. Potential environmental impacts

Will the Project cause:

Encroachment on historical/cultural

areas

X

Encroachment on critical ecosystem

(e.g. sensitive or protected area,

national park, nature reserve etc....)

X

Disfiguration of landscape and increase

waste generation

Removal of vegetation cover or cut

down of trees resulted from clearance at

the sub-station and along ROW?

X The transformeer station is located on the

field land, mainly rice and crop fields.

There is a little impact during the

clearance for grading the station. No

perennials are available in the project area.


_______________________________________________________________________________


NPC

Change of surface water quality or

water flows

X - At the Hoi Hop 110kV transformer

station, a 37m-long temporary road will be

provided across a small canal used to

irrigate interior fields. The chanel can be

filled and prevented its stream flow if

proper construction measure is not taken.

Increase water turbidity due to

run- off and erosion

X - Site leveling and construction of the

station, the station access road can result

in washing away soil, stone and gravel

into the surface water system in the

region;

- Impact on polluting the surface water at

the project area which is assessed

insignificantly can be mitigated.

Waste water from camping sites

is directly discharged to the

surface water resources or not?

X Temporary camping area shall be provided

with good drainage and rubbish collection

system, auxiliary works such as

bathhouse, sanitation toilet for workers’

use.

Construction waste is directly

discharged to the surface water

or not?

X Site levelling & grading and construction

activities can result in washing away soil,

stone and gravel into the surface water

system in the region.

Increase the dust level? X Dust is generated from soil excavation and

station site plan leveling work, especially

in dry season. Affected persons will be the

inhabitants living and working around the

project area.

- Dust is generated by means of transport

of materials and plants during the

construction of the Project. Affected

persons will be roadusers on the route of

construction material transportation at the

locality and on the NH2 bypass and

provincial road transporting materials and

plants.

- The Project will be constructed far from

residential and urban areas so air (dust)

pollution does not affect much the people

living in the Project area;

- The nearest residential area is 600m

away from the Project location so this

impact can be assessed at an average level

and can be mitigated.

Increase noise and/or vibration? X Due to equipment, material transportation,

means of transport of the Project, site plan

grading, pole erection and generator.

Permanent land acquisition X Permanently acquired land area: 3,790 m2

of agricultural land for the station area

which will be permanently acquired.


_______________________________________________________________________________


NPC

Temporary land acquisition Temporary acquired land area: 337.5 m2

of agricultural land (for the part of

temporary road) with the acquired time

about 1 to 2 months.

During the construction of the transformer

station, the households who are in the

planning area but are not acquired their

land by the Project will still cultivate their

crops normally and crop productivity and

quality will not be affected.

Resetlement of households? If yes, how

many households?

X

Would the resettlement site is

environmentally and/or culturally

sensitive

X

Is there any risk of disease

dissemination from construction

workers to the local peoples (and vice

versa)?

X - Maximum proposed construction work

shall be in 2 months in which the station

construction only lasts about 1 month and

the remaining time is mainly for the

installation of equipment.

- Many local workers will be employed so

there are only 10 - 10 workers staying in

the temporary camping area;

- At the station area, auxiliary works such

as bathhouse, sanitation rest room will be

constructed.

- Wastes generating from the camp area

will mainly be solid domestic wastes and

can make inhygienic to the enivronment.

However, rubbish is mainly packings,

remaining food and etc. with a little

amount. Therefore, disease distribution

will be aslo limited.

Is there any potential for conflict

between construction workers and local

peoples (and vice versa)?

X - Contradiction can occur by the following

reasons of: difference in income, culture

and behavior. However, most of the

workers come from this region so there is

no big difference in culture and way of

living.

Are explosive and hazardous chemicals

used within the Project?

X The Project does not use chemicals and

explosives;

In the past, there was any accident

incurred due to landmines or explosive

materials remaining from the war?

X The Project area is the area which has

been inspected, cleared from postwar

bombs and mines and is used for

agricultural production.


_______________________________________________________________________________


NPC

Will Project's construction cause

disturbance to the transportation in the

Project's site?

X Insignificant impact

- Transporation of materials and plants

will affect the normal traffic in the reion in

a short term;

- The transporation of materials from

Hanoi to the construction site in general is

limited so this does not overload the

transport system on the NH2 bypass and

relevant provincial road.

- An intersection between NH2 and access

to the construction site during the

construction will be high-risk locations in

terms of traffic safety because of

separation and integration from means of

transport in construction with main traffic

volume, especially vehicles of transporting

bulky equipment.

Project's construction will cause any

damage to the existing local roads,

bidges or other rural infrastructures?

X

Will soil excavation during Project's

construction cause soil erosion?

X

Will Project need to open new access

roads?

X According to planning map, Hoi Hop

110kV transformer station construction

location has been approved by Vinh Phuc

People’ Committee. A temporary road

connecting to NH2 shall be provided in

the north of the transformer station for the

construction. When industrial zone is

completed and put into operation, such

temporary road will be removed to follow

frontage road in the industrial zone. The

temporary road is of 38m in length and

4.5m in width. Pavement elevation is

suitable for the existing NH2 bypass.

Longitudinal gradient shall be i= 0.01;

road cross-section shall be i = 0.01; curve

radius is 6m. Its embankment structure:

subbase, thiclness of 150, placed riprap,

stone 4x6, natural subgrade.

Will Project cause fragmentation of

habitat of flora and fauna?

X

Will Project cause impact on air

quality?

X - Impact on the environment caused by

exhaust of means of transport during the

transportation of materials which shall be

covered against scattering will be

insignificant.

Will Project cause accident risks for

workers and community during

construction phase?

X - Reason: this can happen to workers or

people surrounding the Project area if

safety measures are not paid attention.


_______________________________________________________________________________


NPC

Will Project generate hazardous wastes

including PCBs from the replacement of

transformers?

X - No oil having PCBs and toxic chemicals

will be used for the Project;

- The operation of the station will use

some chemicals available in such

equipment as battery, insulating oil, grease

oil and etc. These substances shall be

registered and managed in accordance

with regulaitons on management of

harmful waste in Vietnam in Circular

12/2011/TT-BTNMT dated 14/4/2011.

This work has been implemented in many

years at other stations of Electricity of

Vietnam and will be applied for the

Station Improvement Project.

Will Project cause risk to safety and

human health (electric and magnetic

fields, electric shock etc.)?

X - The electric line and transformer station

shall be designed in accordance with

specifications of the Standard ensuring

that EMF level (Electromagnetic Field) <

5 kV/m. The sub-project after completed

and put into operation will provide active

support to the local socio-economic

development and development of

handicraft and services industries;

Improve the quality of living for the local

people because power is supplied

sufficiently and stably.

mass organizations and local electric power office, of three households whose land will not be

taken back but they are cultivating crops on the land around the area of the station.

Problems concerning environmental impacts worried by the consulting households comprise:

- The Hoi Hop 110kV Transformer Station has to build a temporary road about 40

meters long passing through a small canal for the irrigation of the rice fields. What measures

to be taken so as not to fill and block the flow of this canal?

- Is the building of the Transformer Station likely to cause pollution to the surface water

of this canal due to the flushing of earth, stone and raw materials into this source of water?

- The raising of the foundation of the station to a height of 9,2 meters is different with

the present level for about 1 meter, will its cause flood to the surrounding areas?


_______________________________________________________________________________


NPC

- The building of the temporary road linking with Highway 2 for the construction of the

station creates functions that will be high-risk sites for traffic safety. Has the Investor any plan

or measure to avoid the risks?

- During the period of construction of the station, will the households in the planning

area whose land is not taken back by the project be able to cultivate their crops normally?

- Will the project create toxic wastes?

- The compensation money will be paid according to current regulations. However, in

this area, there are constant transfers, and buying and selling of land, it is requested that the

compensation money be changed depending on the time when the compensation is made.

The Investor has the following feedbacks:

- Reasonable construction measures would be taken when the temporary road is build

such as leveling the ground and dredging the vegetal layer for about 25-30 cm deep, then

pouring lining concretes and building embankments along both sides of the canal with rocks.

Laying concrete conducts of D= 500 for normal flow of water. After that, leveling it with sand

to make the foundation of a side way so as not to block the flow of the canal.

The raising of the foundation of the station to a height of 9.2 meters, different with the present

level of about 1 meter, with not cause flood to the surrounding areas because a design plan

has been made for building a proper system of sewerage inside and around the transformer

station.

- Planning construction activities for the time when there is the least traffic flow. Clear

noticing boards will be posted at junctions.

- Having plans and measures to avoid accidents and risks at the sites of junctions with

Highway 2 such as limiting the time of traffic hindrance, posting workers for traffic guidance

whenever there is a vehicle stopping temporary on the road for loading and unloading

materials and equipment.

- During the period of construction of the transformer station, the households in the

planning area whose land is not taken back by the project could continue to cultivate their

crops normally; the productivity as well as the quality of their crops would not be affected.

- The project does not create any toxic wastes.

- The compensation money proposed at the meeting is provisionally calculated

according to current regulations and could be changed at the actual time of project

compensation.

- The building of the Transformer Station shall have certain influences on the locality.

The Investor and the construction contractor shall have measures to positively reduce the

influences caused by the project.

Activity 4: Reviewing and adjusting the Plan for Environment Control in line with the

opinions contributed.

Activity 5: Disclosure of the EMP.

The PMU will disclose the EMP at the Peopele’s Committee of Hoi Hop Ward, Vinh Yen

City, Vinh Phuc Province before the appraisal of the DEP project.

The EMP copies in Vietnamese and English will also be sent to the Vietnam Development

Information Center at 63 Ly Thai To street, Hanoi City for information disclosure.

The EMP copies in English will also be disclosed at the InfoShop of the World Bank in

Washington DC.

Activity 6: Community Reference in the process of establishing the Project

NPC

In the Project establishing Stage, independent environmental consulting specialists shall be

hired to supervise the realization of EMP and collaborate with the Investor to organize the

reference of opinions of the administration, non-governmental organizations and the

households affected by the realization of the EMP of the Project. The collected opinions (if

any) shall be conveyed to the Invector. After that, the Invector would collaborate with other

invectors in order to realize satisfactorily the EMP or update this Plan for Environment

Control (if necessary).
