1. INTRODUCTION
1.1. Project Background
The Word Bank (WB) financed Hanoi Urban Transport Development
Project (HUTDP) is an important component in the Master Plan of
Urban Traffic of Hanoi People’s Government for improvement of the
urban traffic. This project will play an important role in solving
the three problems that Hanoi City is facing, improving the urban
ambient air quality and living conditions of the residents. It will
stimulate the coordinated social, economic and environmental
development of Hanoi City.
The Environmental Impact Assessment of this project shows that
the project will negatively impact the environmental conditions
along the project roads and in some regional areas. However, it
will positively impact the ambient air quality as well as the
control of the atmospheric pollution in the whole urban area,
especially in the densely populated central urban area. The
Environmental Management Plan (EMP) of this project, as a part of
the environmental impact assessment documentation of HUTDP, is one
of the important documents requested by WB. The purpose of EMP is
to ensure the implementation of the mitigation measures proposed in
EIA. For the project to be environmental feasible, the necessary
mitigation measures must be implemented.
1.2 Objective, Strategy and Performance Indicator of EMP
1.2.1 Objective
As indicated in the EIA of this project, traffic noise and tail
gases from motor vehicles are the main adverse impacts imposed by
the project on the area along the project roads. Besides, the land
using mode will be changed by the construction of roads, resulting
in separation of communities.
Detailed descriptions are given in the EMP for the mitigation
measures for different environmental impacts, environmental
management, supervision and monitoring scopes. Thus, the EMP can be
used as a guidance document for the implementation of the
above-mentioned activities.
The EMP plays the following roles:
· Definition of the environmental mitigation measures for the
impacted targets. The Project Management Office, environmental
assessment team and design institute have made on-the-spot
investigation and confirmation for the impacted sensitive receptors
of this project. On this basis, effective mitigation measures have
been developed collectively. These mitigation measures have been
incorporated into the engineering design of this project to ensure
their implementation.
· Providing an environmental guidance document. The EMP, after
being reviewed by WB, will be the environmental document that will
be provided to the construction supervision unit, environmental
supervision unit and other project-related institutions during the
construction and operation phases.
· Definition of roles and responsibilities of relevant
institutions. The roles and responsibilities of the relevant
functional organizations and administrative institutions are
defined. The approaches for communications and exchanges between
different institutions are also proposed.
· Development of the programs for environmental monitoring in
construction and operation phases. EMP has developed the
environmental monitoring programs for the construction and
operation phased, so as to guarantee the effective implementation
of the environmental mitigation measures and to handle the
unpredictable environmental problems or contingency at the earliest
time possible.
1.2.2 Strategy and Performance Indicator
In order to minimize the environmental impact of this project,
the following overall environmental objectives and performance
indicators for the environmental management in the construction and
operation phases have been worked out by the joint efforts of the
officials of the WB, the international consultants, EA team and the
Project Construction Office.
Overall objective: maintaining the sustainability of the urban
social economic and environmental development, improving the urban
environmental quality, and minimizing and reducing or otherwise
compensating adverse impacts to the communities and the
environment. The detailed actions and indicators are as
follows.
Actions:
· Developing and implementing an EMP and monitoring program
· Developing and implementing the MVECS to mitigate the impact
on the ambient air
Indicators:
· Inspecting the monitoring results of the monitoring factors
listed in the environmental monitoring program during the
construction and operation phases
· Implementing all the environmental mitigation measures
developed in the EIA according to the specified schedule
· Developing the Motor Vehicle Emission Control Strategy
(MVECS)

Hanoi Urban Transport Development Project is a complex system
consisting of several sub-projects or components. Among the
components there will be physical works as well as improvement and
upgrade of relevant management systems and software. According to
the common characteristics of various components, the project may
be divided into five categories: road infrastructure construction,
traffic control and safety, public transit improvement, road
maintenance and environmental protection components. According to
the EIA Report of this project, two of four components such as road
infrastructure construction engineering, BRT will cause larger
adverse impact on environment, so corresponding environmental
mitigation measures shall be adopted for these two components, and
it is the core content of this EMP. While the other two
sub-projects such as the traffic control and safety engineering and
environmental protection engineering will produce larger positive
benefit to the whole environmental quality of Hanoi City, the
negative environmental impact from these two sub-projects during
the construction and operation phases is tiny, and the
environmental positive benefit produced by them will be reflected
from the overall environmental monitoring results during the
construction phase. The Schedule of BRT components is shown in
Table 2.2. The Schedule of Road components is shown in Table
2.3.

3. SUMMARY OF ENVIRONMENTAL IMPACT OF THE PROJECT
This chapter summarizes the adverse environmental impacts
produced by this project; these data mainly are from the EIA Report
of this project. The detail see EIA please.
4. ENVIRONMENTAL MITIGATION MEASURES
Construction of this project will execute Management Regulations
on Environmental Protection for Construction Projects promulgated
by the Ministry of Construction- Decision No 29/1999 and so that
devices for environment protection and the main construction can be
designed, constructed and operated at the same time.
To guard against the adverse impact of the project, the
following detailed actions shall be taken in each stage of the
implementation and operation.
In the period of choosing works and designing, various potential
impact factors shall be analyzed, and the best measures shall be
designed to reduce the adverse impact on the environment.
During the construction phase, environmental impact mitigation
measure shall be taken for the involved units or people, for
example, to set acoustic barrier, and double-layered sound
insulated window, so as to reduce the noise impact on the
environmental sensitive receptors.
During the operation phase, it is necessary to carry out
long-term action plan to improve the urban environmental quality,
such as traffic control, limits of downtown traffic, vehicle end
gas control strategy and rational allocation of the city’s
layout.
4.1 Project Design Phase
Selection of Alternatives
Many of the adverse impacts of project can be best avoided
through the selection of alignments/designs with the least adverse
environmental and socio-economic impacts during the feasibility
study and design stage. In this project, alternative alignments and
alternative design (i.e., elevated viaduct versus ground level
roads) have been proposed and evaluated in terms of potential
environmental impacts, as well as transportation, engineering and
cost considerations, before an optimal option is selected for the
design of the project.
Table 4-1 shows the impacts to the environment in construction
of some of BRT routes as follows:
- The section from Dai Co Viet Rd into Giai Phong Rd to the
flyover with three options, each option has its own strong and weak
points. The above table shows that Alternative 2 is the optimal one
which bring about numerous environmental benefits (apart from its
own benefits) such as avoiding traffic jams, accidents due to
changes of lanes, no impacts to pedestrians, simple vehicles and
motorbikes, reduction of tail gas pollution from individual means
of transport. However, other environmental disadvantages should be
settled like traffic jams even though less than those of
alternative 1 (from the middle into left lanes at Vong T-junction)
and limiting the access of other means of transport on both sides.
As such, middle lanes are proposed for BRT routes in this
section.
Table 4.1. Comparison of Engineering Design Alternatives
Section from Dai Co Viet Rd - Giai Phong Rd - Flyover
Alternative 1
Advantages of BRT along road sides
1. BRT along road sides allows other means to travel
Disadvantages
1. Traffic jam, accidents due to interchange with other
lanes;
2. Affecting pedestrians and other simple vehicles from the
small roads into Giai Phong Rd to the right
Alternative 2
Advantages of BRT in the middle of the roads
1. No impacts to pedestrians, simple vehicles and
motorbikes;
2. Settling traffic jams, accidents due to changes of lanes.
Disadvantages
1. Causing traffic jam but less than alternative 1 (from middle
lane into left lanes from T-junction - Vong St);
2. Restricting access of other means along both sides.
Alternative 3
Advantages of BRT along barriers
1. BRT along pavements will allow for other means to travel
Disadvantages
1. No transit for passengers at Truong Chinh Transit
station,
2. BRT to viaduct reduces flexibility of crossing node - Nga Tu
Vong;
3. Difficult for BRT passengers at Truong Chinh stop where
traffic density is high
Channel zed in Hai Ba Trung and Trang Thi
Alternative 1
Advantages:
1. Reduction of individual means;
2.Reduction of noise pollution, tail gas from individual
means
Disadvantages
1. Causing circle traveling for other means which change
directions;
2. Affecting daily activities (and economics) of people in the
streets whose direction are changes;
3. Taking space in terminals/stops.
Alternative 2
Advantages:
1. Minimization of cycle way of alternative 1;
2. Stop the disputes, safety for people;
3. Reduction of noise pollution, emitted gases from individual
means (due to reduce number of fleets)
Disadvantages
1. The coordination with the West is reduced;
2. Affecting daily activities (and economics) of people in the
streets whose direction are changed;
Alternative 3
Advantages
1. Improving traffic capacity for means to the West (limitation
of alternative 2);
2. Stop the disputes, safety for people;
3. Reduction of noise pollution, emitted gases from individual
means (due to reduce number of fleets)
Disadvantages
1. Changing the traveling habit in city center;
2. Affecting daily activities (and economics) of people in the
streets whose direction are changed;
3. Causing big dispute in Le Duan/Nguyen Khuyen).
Channelise in Hai Ba Trung and Trang Thi, there are three
proposed alternatives with its own strong and weak points. Table
4-1 shows that the alternative 2 is the optimal one which can help
to settle the circle traveling as those of alternative 1; Stop
conflicting points at junction Le Duan/Nguyen Khuyen, securing
safety for people, reduction of noise level as well as emission of
toxic gases from individual means of transport.
Table 4.2clearly presents the environmental impacts of the two
options AI and AII. Regarding Option AI, there are more advantages
and negative impacts are less than Option AII. The disadvantages of
the option comprise traffic safety at terminals and stops which can
be overcome. As such, middle BRT routes are proposed in this
section.

less impacts to landscape, traffic safety and tail gas dispersion.
Economic benefits are numerous which are shown in fewer
requirements for resettlement and compensation for affected people
due to losses of business sites and saving of construction cost
4.1.1 Noise
Route selection and site selection for new roads and expended
roads shall move around the sensitive receptors as possible as it
can be, and unless absolute needs, viaduct will not be built.
Mitigation measures at the design stage are those which are
considered during and/or incorporated into the design.

Overview of mitigation measures for the Ring road project. The
World Bank financed ring road project has been completed and
operational since 2007 and noise mitigation measures have been
gradually implemented along the ring road. The actual noise barrier
length is about 2700m . The additional noise barrier has been
installed in response to the strong public reaction on the
increased noise from the inner ring road. The other important noise
mitigation measure, installation of double glazed windows in
sensitive receptors, has been gradually implemented.
In general, the noise barriers are most effective to three to
six floors of the buildings targeted for protection, with average
noise reduction of about 2 to 4.7 dB(A). Higher floors are
generally beyond the noise barrier protected area and have no
measurable noise reduction. The lower floors on the other hand, are
mostly impacted by the noise from the ground level traffic for
which the noise barriers mounted on the elevated viaduct have no
effect.
Double glazed windows have been installed in hospitals, school
and houses next to the road. The monitoring program at the two
locations show that noise can be reduced by 26-27 dB(A) at the
hospital (with a vacuum lawyer between two pieces of glasses) and
17-22 dB(A) at the school (ordinary design with two layers of
windows put together) when the windows are closed. When the windows
are open, the reduction is about 6-10 dB(A) compared with the noise
levels one meter outside the same windows.
The lessons learnt from the inner ring road noise mitigation,
which will be included into the consideration of mitigation measure
planning and design for roads include:
· For multi stories buildings, the noise barriers should be
higher. A noise barrier 5-7 m tall as originally designed, compared
with the current height of 3 m, would significantly increased the
protected area;
· The lack of seal of noise barriers at the structural expansion
joints and the poor design in aluminum frame of the noise barriers
are to blame for the less than desired effectiveness of noise
barriers;
· The noise barrier installation is not well planned. In some
areas noise barriers are installed where is no sensitive receptors
to protect. Such waste of effort should be avoided and the location
of noise barriers should be carefully planned through site
investigation and acoustic study; and
· Double glazed windows prove to be very effective measures for
noise attenuation for indoor environment. It seems that to meet the
noise standards at the sensitive receptors, the windows are
required to be closed; therefore, the ventilation must be resolved
to ensure the effectiveness of double glazed window as a noise
control measure.
In the following section of Hoang Quoc Viet extension road,
noise barrier will be built to protect the sensitive receptors
nearby:
· North side at Dong Xa residential area for 500 m long; on the
Southern side, 500 m long. The noise barrier will be 3.5 m high
using absorbent materials, considering the fact there is no high
rises in the directly impacted area. As the buildings in the
villages are mostly two stories high at about 10 m to the road for
the closest houses. To this height, the noise barrier will be most
effective in noise reduction, particularly this part of the road
will be single elevated viaduct only with no roads on the ground
level. It is expected that the noise level equivalent at the houses
will be reduced from the originally predicted levels by about 15-20
dB(A). The residual impacts at the village houses following the
noise barriers will be about 60 dB(A) during the day time and about
50 dB(A) at night, which meet or slightly above the applicable
Category II standard ( TCVN 5949-1998).
· Based on the lessons learnt from the inner ring project, the
noise barrier to be installed will be carefully designed using
quality materials. In particular, the aluminum frame of each panel,
between panels and between the structural expansion joints will be
well sealed to enhance the noise reduction function.
Double glazed windows. The experience gained from noise
mitigation of the Ring Road project has showed that noise barrier
alone may not be adequate in terms of noise reduction to the
acceptable levels while installation of double glazed windows at
the sensitive receptors is the most effective measure to protect
indoor environment from noise impact. Buoi interchange (including
link road Buoi- Hoang Hoa Tham) with 600 m of road will take such
measure to noise mitigation at the most sensitive receptors.
· Along the Nguyen Thai Hoc street, a bus stop of BRT route will
be located near Primary school when 3 stories classroom building.
The first and second floor of the building will be mostly towards
the classrooms on the third and fourth floor. There are a total of
10 classrooms on these two floors with a total window area of 120
m2.
· The first building of University of Civil engineering and
Hanoi University of Polytechnic located app. 100 m from the
proposed BRT Giai Phong corridor, however, noise level is expected
to be able to meet the applicable standards. No further mitigation
is needed.
· Bach Mai hospital is about 50 m from the proposed BRT road.
But it is located near railway station. The effected noise level in
this area caused by train is more than by BRT. However, it is
recommended that the first building of the hospital shall be
installed by Double glazed windows with an estimated area of 120
m2.
4.1.2 Vibration
We will take the following measures in engineering design to
reduce the potential influences on vibrating environment.
· Potential vibration caused by the expansion seals/joints
between pre-fabricated concrete plates and between concrete plates
and bridge columns of the interchanges will be given sufficient
considerations during the design. The support column design will
also affect the vibration which will be considered in the design as
well.
· Greater improvement in the materials spread on the pavement of
the road and the plan ness of the road will be made. The asphalt
will be adopted as the surface material. The smoothness of road
surface will be strictly controlled, because 1 mm decreasing of
smoothness contributes to 4 dB reduction of vibration level.
· The land use along the project roads will be properly
arranged. The vibration sensitive buildings will not be placed
within 40 m along project roads. Such considerations have been
incorporated into the Mater Plan of Hanoi City and will be carried
out by and under the supervision of Hanoi Planning Bureau.
4.1.3 Ambient Air
To facilitate the dispersion of motor vehicle tail gases, the
new high-rise buildings to be built along the project roads will be
located outside 20 m of the red line.
4.1.4 Water Environment
Domestic sewage from the public transit stops shall be drained
into the municipal sewage pipeline after being treated in
cesspools. Sewage from vehicle cleaning at the public transit
depots in Quang Lai, Ba La, Trung Van and Van Dien shall be
discharged after being treated by oil-water separating treatment
facility.
4.1.5 Landscape Design
Considering environmental beautification and landscape design in
engineering design, making the road, viaduct and bus depots
coordinate with each other to the utmost.
In the design of road reconstruction and expansion, make utmost
efforts to protect the trees and the green belt at both sides of
the road; as for the place that must be occupied, the trees that
can planted in another place must be planted in the another places
as much as possible.
· According to Hanoi Urban Green Regulations, as for the ratio
that green land in this project accounts for in the total area of
the land, the road with the width of under 40 m is not less than 20
per cent, the road with the width between 40~50 m is not less than
25 per cent, the road with the width of over 50 m is not less than
40 per cent and the bus depots is not less than 25 per cent.
4.1.6 Sunshine
Determine the width of the red line at elevated section
according to the design principle of controlling the sunshine
disturbance into the minimum degree and control the distance
between the red line at elevated section and the sensitive
buildings close to the sunshine into 5 m, and this measures will be
supervised and performed in the urban planning and during
construction and development of the road at both sides of elevated
section by Hanoi Architect and Planning Bureau.
4.1.7 Land Acquisition, Demolition and Resettlement
During position selection and design of newly-constructing,
reconstructing, expanding road and public transit bus depots, it is
the important guideline for the project decision-making department
to reduce the land acquisition and demolition and resettlement to
the minimum degree.
4.2 Construction Phase
The construction of this project will have influences on the
acoustic environment, vibration environment, ambient air, water
environment, vegetation, community, traffic, municipal facilities
and cultural and historical sites and so on. Although most of the
influences is instant and recoverable, thorough attention must be
paid to the estimation on environmental impacts.
4.2.1 Acoustic Environment
Although the noise produced in construction is inevitable
entirely, the impact from the noise on the environment around it
can be mitigated to some extent. The Constructor must to make the
noise in construction site meet the requirements of Permitted noise
level in Construction Site.
The following measures to reduce the noise will be performed by
the Contractor:
Prohibit using the equipment with high noise at night
(22:00~6:00), such as pile driver,crusher, bulldozer, excavator,
compactor, generator, electric sew, concrete electric vibrator and
so on. Any operations extended beyond these timeframe as may be
required by the construction needs must apply and receive approval
from relevant authority. This requirement will be strictly enforced
in the RR No2 and Hoang Quoc Viet road construction which will
basically eliminate the noise impacts at night, as well as the
after lunch nap time, when the standards exceed would be worst.
Use the machinery with low noise or the equipment equipped with
sound eliminator or sound insulation cover for example, generator
used in construction site will be supplied with sound eliminator or
according to the environmental situation around the construction
sites.
Arrange construction time and equipment reasonably to make the
construction which may produce larger noise avoid the sensitive
receptors and time of sound environment and maintain equipment
regularly to keep its good working state. As for the construction
sites with a little larger noise, install temporary sound
barrier.
As for the large construction structures, especially those used
in many viaducts in this project, they will be prefabricated
outside the construction sites and then will be transported to the
construction sites to erect.
As for the construction which is necessary to be performed at
night, the Contractor must submit it to the People’s Government of
Hanoi City for approval in advance of construction. The Project
Construction Office will install sound insulation windows at the
impacted sensitive receptors according to the requirements of this
environment management plan ahead of 15 days before construction
and release its construction report on the newspaper before 2 days.
The telephone numbers for complaint will be given on the newspaper
and in the construction sites.
Where possible, columns will be installed using excavated holes
and onsite casting. If steam, turbine or hammer style drilling
machines must be used for column construction, the contractors must
apply to PMU first and these drilling activities will be restricted
to certain hours of the day (primarily morning and afternoon while
evenings and nap time at noon will be strictly prohibited from
using such drillers).
According to the above assessment, Dong Xa ward, Xuan La commue
will be the most seriously impacted sensitive receptors during
construction. In fact, the later section of this report will show
they are also the most significantly impacted by noise and motor
vehicle exhaust emissions during the operation period of Ring Road
and Hoang Quoc Viet Road. Specific mitigation measures have been
designed and will be taken at these locations for reduce or avoid
the long term impacts during operation phase. These include
relocating Xuan La primary school to an area not to be impacted by
the project and install double-glazed windows to the first row of
the residential housing in Xuan la commune. To mitigate the noise
impacts from construction activities, these measures will be
implemented at the beginning of the construction phase. For
example, Xuan La primary school will be relocated prior to the
construction to completely avoid the impact. Double-glazed windows
at the mostly affected houses will also be installed at the
beginning of the construction for noise impact mitigation.
In addition, the following measures will be taken to further
avoid or mitigate the construction noise impacts:
· Structural elements for bridges and elevated viaducts will be
made in factories to avoid on-site concrete mixing and
compacting;
· Low noise machinery will be selected where possible. High
noise machinery such as power generators will not be allowed to sue
at the site; but if they are necessary for construction work, noise
temporary barriers or silencer will be installed;
· Appropriately schedule the construction activities to avoid
sensitive time and/or sensitive locations where possible;
· Noise and vibratory activities will be arranged to be
completed within the quickest time possible to reduce the impact
length;
· Construction trucks movement will be arranged to avoid
residential areas where possible;
· According to relevant laws and regulations, if the
construction noise still exceeds applicable standards, especially
night time construction, the contractors will apologize and
compensate the affected residents, students in classrooms and
dormitory, or others affected.
4.2.2. Ambient Air
· The following measures will be taken during construction phase
to mitigate the impact of air-borne dust and other air
emissions:
· Excavation and demolition site will be water sprayed to
maintain certain moisture levels, loosed earth and dry backfill
materials will also be water sprayed to prevent or minimize dust
from air borne; On dry days, water will be sprayed at least twice a
day, once in the morning and once in the afternoon right after the
noon break.
· Materials will be stored in appropriated places and will be
compacted where possible; for bulk materials which cannot be
compacted well, water spray or cover will be applied to minimize
dust;
· All construction waste will be promptly removed from the
sites, daily if possible;
· Earth and bulk materials transportation will be loaded in such
a way they will not leak during transportation and will be
covered.
· Before leaving construction sites, trucks wheels will be
washed to clean the dirt which would otherwise be carried away to
the streets;
· Strictly prohibit burning of construction waste at the sites;
and
· Asphalt and concrete mixing plants will be located in the area
at least 500 m leeward from the nearest residential or other
sensitive receptors to ensure that the emission from these
facilities will impact the sensitive receptors. The asphalt plants
will be required to equip with effective emission control
facilities to meet the emission standards in relevant state and
provincial air emission standards. All these location and emission
requirements will be included in the tendering documents
distributed to the bidders for the pavement work and eventually in
their contracts to become contractual obligations for the
contractors working for the project.
During construction, the Hanoi Urban Traffic Management Bureau
will do well in traffic control in urban area. According to
construction plan, set warning signs at the entrance to the city to
remind the vehicles of traveling from the external roads around the
city. Do well in traffic control on external roads to ensure the
unblocking of the roads and prevent the traffic congestion so as to
reduce the impacts from the tail gas of the vehicle on the ambient
air. If the vehicles are blocked due to the road construction in
urban area, the traffic management department will set up the
instant vehicle traveling management method, for example,
regulating the traveling route for the taxi with odd and even
dates, prohibiting turning left at the main crossing and setting
one-way lane and so on.
4.2. 3. Water Environment
The Contractor will take the following measures to minimize the
impacts from construction activities on water environment.
· Prohibit draining and flowing waste water from construction
randomly.
· Clear the construction site in time, only when the waste water
from construction is treated in the temporary sand settlement bank
can it be drained into the drains to prevent some little matters
such as sands and some sundries such as some construction rubbish
from being draining into drain pipeline.
· Prohibit storing construction materials and rubbish at the
place where the waste water from the construction sites enters the
drains and pay attention to clearing the accumulating mud to
prevent drain pipeline from choking.
· The toilet for constructors in construction site shall set
temporary cesspool and the sewage will be drained into the drain
after pretreatment in cesspool.
· Besides enforcing management on the drainage of domestic
sewage, the Contractor shall offer training to the constructor on
basic environmental protection to improve the consciousness and
responsibility of environmental protection.
4.2.4. Solid Waste
The following measures will be taken during construction to
mitigate the impacts of solid waste to the environment:
Contractors will be requested to comply strictly apply first to
TUPWS and Hanoi Urban Environmental Company (URENCO) to receive
appropriate approval and permits and dispose the waste in
designated areas.
As per TCVN 6696-2000 stipulate that trucks loaded with bulk and
loose materials and waste must be loaded properly, covered and
washed of their exterior before allowed on the roads. Such trucks
are not allowed to leak or cause air-borne of the materials loaded
during transportation and the transportation can only be made
within the designated time and along the designated routes.
Waste materials which can be used again will be recycled;
Temporary waste storage areas at the construction sites will be
carefully selected to avoid water front or causing traffic
congestion, inconvenience to the pedestrians, residents, and others
in the nearby communities; and
Transportation of construction waste will avoid peak hours,
avoid sensitive areas, and will use approved routes.
4.2.5. Urban Ecology
The following measures will be taken to minimize the
impacts:
· Where possible, plants including trees, flowers, and bushes
will be relocated to other places or back to the project area
following the completion of the construction, instead cut and
wasted;
· The construction activities will be limited within the red
line area and not to occupy farmland;
· Buildings under demolition will be surrounded with nylon cloth
or metal sheets or wood boards to minimize the visual impacts to
the communities as well as for dust and safety control;
· The project area will be landscaped and planted following the
construction. The green area will be no less than 20% of the total
project area. The landscaping plan will result in a net increase in
green space in the project area.
4.2.6. Traffic Management
To mitigate impacts to the traffic on the existing roads,
construction activities will be well planned in consultation with
the local traffic police. The specific measures to be taken include
the following:
· The most traffic affecting activities such as
loading/unloading, beam lifting, and bulk materials transportation
will be scheduled for the time when the traffic on the roads will
be the lightest such as weekends, holidays mid-day around the noon
time or evenings.
· No traffic affecting construction activities will be allowed
during the rush hours in the morning and early evening;
· Public notices in the form of public boards at the
construction sties will be provided to inform the road users of the
time, length and type of traffic affecting construction activities
and possible congestion.
· The public notice will also advise the road users of possible
detoured roads identified by the traffic police as alternative
routes to avoid the congestion on the roads affected by the
project;
· No construction materials and debris will be allowed to store
and pile on the roads or the pedestrian areas;
· Construction vehicles parking on the roads will not be allowed
unless it is absolutely necessary. Such parking will be kept to the
minimum and be removed as soon as it is possible; and
· During the loading/unloading, viaduct structural lifting and
installation, the contractors will be requested to contact the
traffic police to either have the police on site or have their own
staff on-site to help direct the traffic, to minimize the traffic
congestion and to ensure the safety.
4.2.7. Community
The following measures will be taken to mitigate the negative
impacts on the community from the construction of the project.
· All of the roads under reconstruction in urban area will be
constructed in half-closed manner and leave passages for the
pedestrians, bicycles and buses.
· Build temporary roads and temporary bridge for the units and
the residents along the line and set necessary safety measures to
ensure the unit and the residents can go out conveniently and
safely. At the same time, perform centralized construction and
quicken the construction progress to reduce the impacts on the
communities.
· As for the section where some schools are located, carry out
construction in the summer holiday or in other holidays to reduce
the impact on the going of the students.
· All of the construction materials will be stored on special
yards by categories and types and kept by designated persons. The
discarded materials will be removed out of the site to reduce space
occupation and traffic inconvenience.
· As for the resident areas and the units that are separated due
to being removed, rebuild the fence within one month after
accomplishing removing to reduce the impacts from the external
environment on the community security.
· During the construction of ramp of Buoi and Cau giay
interchange as well as Dam and Nhue bridges, build safety passage
and take safety measures to ensure the safety of the
pedestrians.
· The hospital can anew establish its gate, so does the school;
at the same time, set some facilities such as gangway and guard
fence.
· Road construction will be carefully planned and implemented to
avoid damages to underground utilities. Necessary protection
measures will be taken for various underground pipelines and
cables.
· In road sections where traffic will remain, the street
lighting will be maintained at the original levels. No damage or
disruption of street lighting will be allowed.
4.2.8. Others
Other measures to be taken during the construction phase
include:
· The contractor will be request to halt the all construction
activities immediately if any archaeological or other cultural
properties are found (chance finds) during excavation and to
properly protect the site which such finds are uncovered. Cultural
authority, as well as PMU and EA team, will be noticed promptly.
Only after a thorough investigation by the cultural authority and
specialists and a clearance is provided, will the contractor be
allowed to resume their construction activities at the site.
· The contractor will be request to provide safety shelters at
the construction sites, particularly overhead construction sites,
to protect the public from any safety accidents. Warning signs will
be provided to alert the public of potential safety hazards at and
around the construction sites.
· The PMU recognizes that contractors working on the road
component will be a key in environmental management, pollution
control and impact mitigation during construction. A number of
measures will be taken to ensure that the contractors will be aware
of their responsibilities and obligations in environmental
protection. All contractors and construction supervision will be
required to participate in a mandatory environmental training
program prior to the start of construction onsite. The above
mitigation measures will be, where appropriate, included in the
tendering documents for contractors and eventually in the
construction contracts so that they will be the contractual
requirements for contractors working on proposed road.

building refuse and building materials on the construction sites,
and site recovery and hardening shall be managed strictly.
According to the investigation on change of the concentration of
PM10 surrounding the construction sites, the distance between the
material plant, mixing station and other temporary material plant
for construction and the residential areas and environmental
sensitive receptors shall not be less than 50 m. In the
construction phase, the municipal traffic management departments
shall do well the traffic dredging work. According to construction
plan, set warning signs at the entrance to the city to remind the
vehicles of traveling from the external roads around the city. Do
well in traffic management on external roads to ensure the
unblocking of the roads and prevent the traffic jar so as to reduce
the influences from the waste gas of the vehicle on the environment
and air. If the vehicles are blocked due to the road construction
in urban area, the traffic management department can set down the
instant vehicle traveling management method, for example,
regulating the traveling route for the taxi with odd and even date,
prohibiting turning left at the main crossing and setting one-way
lane and so on.

Water environment
Prohibit draining and flowing waste water from construction
randomly. Clear the construction site in time. Only when the waste
water from construction is treated in the temporary sand settlement
bank can it be drained into the drains to prevent some little
matters such as sands and some sundries such as some construction
rubbish from being draining into drain pipeline. The toilet for
constructors in construction site shall set temporary cesspool and
the sewage will be drained into the drain after pretreatment in
cesspool. Besides enforcing management on the drainage of living
waste water, the contractor shall offer training to the constructor
on basic environmental protection to improve the consciousness and
responsibility of environmental protection.
Constructor
Recovery of vegetation
As for the green belt damaged by construction activities, if
they can be planted in another place, take protective measures to
plant them in another place after the construction. If it is
necessary to cut them due to the construction need while they can
not be planted in another places, they will be compensated
according to the principle of "cutting one, compensating two".
There will be 378 trees to be cut within the range of the project
and 756 trees will be planted as the compensation after the project
is accomplished.
Constructor, Hanoi Landscape Bureau
Community
All of the roads under reconstruction in urban area will be
constructed in half-closed manner. Build temporary roads and
temporary bridge for the units and the residents along the line and
set necessary safe measures to ensure the unit and the residents
can go out conveniently and safely. As for the section where some
schools are located, carry out construction in the summer holiday
or in the holidays. All of the construction materials will be
placed in the special sites in order according to the
classification and type, clear and transport the waste from the
construction in time to reduce the influences on the land occupied
by the materials and the traffic. As for the resident areas and the
units that are separated due to being removed, rebuild the fence
within one month after accomplishing removing. During the
construction of ramp of Dam River Bridge and the over cross at
Hoang Quoc Viet Road, build safety passage and take safety measures
to ensure the safety of the pedestrians.
Constructor, Project Managemt. Office
Traffic
When setting down road construction plan, pay attention to
planning and reasonable arrangement; at the same time perform
construction in different period to reduce the traffic jam due to
the same direction of the vehicles. This project will be
constructed in half-closed manner and allow the buses and the
bicycles to travel while prohibit the traveling of the vehicles
through Hanoi City to ensure the unblocking of the buses. In the
busy section, the crossing of the road can not be constructed in
fully closed manner, but in half-closed manner, at the same time
set one-way street to ensure the unblocking of the bus. Enforce
traffic management and organization. All of the vehicles through
Hanoi shall travel along the external ring route and it is
prohibited to cross the urban area to reduce the traffic pressure
of the roads in urban area. Control the variation and the type of
the passing vehicles, set lane on the special sections and increase
the change circle of traffic indication light to try to reduce the
traffic flow on the main truck. Organize circumambulating line and
bicycle line. Perform scientific management and improve the quality
of the traffic policemen to enforce traffic management ability;
emphasize on improving the quality of the drivers to reduce the
traffic jar due to the man-made factors. Set iron separation fence
at both sides of the tracks of the roads for vehicles in main urban
areas. Enforce the management on the anchoring vehicles on the road
and make it leave as quickly as possible to avoid the influences on
the normal passing of the vehicles so as to increase the passing
ability of the traffic of the roads.
TUPWS, PMU
Vibration
Where possible, columns will be installed using excavated holes
and onsite casting. If steam, turbine or hammer style drilling
machines must be used for column construction, the contractors must
apply to PMO first and these drilling activities will be restricted
to certain hours of the day (primarily morning and afternoon while
evenings and nap time at noon will be strictly prohibited from
using such drillers). Unless there is emergencies (emergent repair,
emergent rescue), at night (22:00~6:00)we will not use any
construction equipment with great vibration influences. The
contractor must set signs at striking sites and give the telephone
for complaint, names of the project, the contractor and the
building unit. Select construction equipment with low noise and
vibration, and maintain it regularly.
Constructor
Municipal facilities
2 days before the construction, the contractor releases public
notice on newspaper or television to the public to make
preparations. If the water is cut off over 2 days, we'll use water
supply truck to supply the influenced people with water. Stoppage
of power, gas or water that may be caused by construction will be
arranged at night (22:00~6:00)as much as possible.
PMU.

4.3. Operation Phase
4.3.1 Noise Control and Acoustic Environment Improvement
● Hanoi DONRE will takes charge of the sustained improvement of
noise standard of vehicle. The Hanoi Traffic Management Bureau of
Hanoi Public Security Bureau, together with Hanoi Environment
Monitoring Station, is in charge of the regular inspection of the
ve
