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
HOI HOP 110kV Substation
_______________________________________________________________________________
Environmental Management Plan 14
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

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.

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.
HOI HOP 110kV Substation
_______________________________________________________________________________
Environmental Management Plan 17
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.

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.

Plan construction activities for a period of the least
traffic volume. At the connection point, signs shall be
clearly marked.
Limit the time of obstructing traffic, arrange workers
for traffic guidance once a vehicle stops on the road to
load and unload materials and equipment.
Affect flooded
drainage by
heightening the
station foundation
bed.
Design and construct proper drainage systems inside
and around the transformer station to ensure that the
rain water does not cause flood for the surrounding
area.
Affect irrigational
canal in the interior
field when
constructing the
transformer station
and temporary road
for the
construction.
Use the waste stone/soil to fill and level the station
foundation. Protect loose material piles by covering
and making drainage paths surrounding such material
piles in order that the loose materials can not block the
flow of the drainage ditch. When constructing the
temporary road over small drainage ditch, it will be
required to level the plan, remove organic layer about
25- 30cm then place lean concrete and construct
revetment with rip-rap. Place concrete culvert pipe D =
500. Then, grade sand for road embankment and
prevent from blocking the canal flow.

VIII. Information reference and publication
In the preparation stage for the project (2010-2011), the following activities have
been realized:
Activity 1: Enquiring and discussing with the local authority about the place of the
transformer station.
Activity 2: Location surveying and investigation, making Environmental Impact
Assessment and plan for environment control.
Activity 3 : Organizing community consultation.
The meeting with the local people was held at Ho Hop Ward, Vinh Phuc Province. The
Investor and the Consulting Company held the meeting to get their opinion of for the
Environment Management Plan Project. The Investor and the Consulting Company Project
explained to the people on the following main issues:
- Presentation of the project: the site for the construction of the Transformer Station and
the need to build the above-mentioned projects;
- Possible impacts on the environment caused by the project;
- Measures to diminish the impacts.
The mass representatives invited to attend the consultative meeting consisted of: 16
households representing the affected households, representatives of the local authority, of
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?
HOI HOP 110kV Substation
_______________________________________________________________________________
Environmental Management Plan 35
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
