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 HanoiPeoples 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 thisproject, 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.

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 protectioncomponents. 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 overallenvironmental 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.

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 citys layout.

4.1 Project Design PhaseSelection 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 ofalternative 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.

environmental impacts. As such, Option C is proposed for both nodes. Regarding

Option C, more environmental benefits can be achieved like less land required, 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

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


29/54



Page 28

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 buildingstargeted 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) and17-22 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 noiseattenuation 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


30/54



Page 29

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 environmentfrom 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 ofPolytechnic 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


31/54



Page 30

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 potentialinfluences 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


32/54



Page 31

occupied, the trees that can planted in another place must be planted in the another

places as much as possible.

- According toHanoiUrban 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 between40~50 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 ofelevated 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 thenoise 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:


33/54



Page 32

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 QuocViet 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 theconstruction 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 Peoples 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 mostseriously 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

- 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 dirtwhich 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 andeventually 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.


36/54



Page 35

- 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;


37/54



Page 36

- 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 landscapingplan 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 onthe 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 thepolice 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.

Page 37

- 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, performcentralized 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 immediatelyif 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.


39/54



Page 38

- 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 akey 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.

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.
