CHAPTER II

BASELINE DATA OF THE ENVIRONMENT

2.1. Meteorology

Hanoi is located in northern delta region of Viet Nam, which is strongly affected by typical tropical-monsoon weather. The province have two distinct seasons: the dry season that lasts from November to March of coming year and the rainy season that lasts from April to October

a) Temperature The average annual temperature is 23.30C, the highest temperature is 41.5° C. The lowest temperature is 8°C. May is the hottest month when temperatures rise close to 34.7°C while January is the coolest month at around 18.8°C

b) Relative humidity The average annual humidity is 83.0%, the highest humidity is 87%, the lowest humidity is 81%. The relative humidity is higher during the rainy season and lower during the dry season

c) Rainfall The rain season in Hanoi is from April to October. Annual average rainfall is 1676.2mm. The rainy days 142 days/year.

d) Tropical Storm:

Storms occur frequently in Hanoi from June to October. The maximum wind velocity can attain 20m/s, sometimes 40 m/s. Storms bring about generally rains during 1-2 days, sometimes 5-6 days. Rainfall can be more 200mm.

e) Stablity of Atmosphere:

Stablity of atmosphere determinates by wind speed and solar radiation in day and cloudiness at night. In the project area, annual average cloudiness is approximate of 7.5/10. The most cloudy period is in the end of winter, among most cloudy month is Mars with average cloudiness of 9/10, less cloudy months is 4 months at the end of year, so minimum cloudy months is October and November with their cloudiness is 6/10.

2.2. Geological Conditions:

The structure of the ground in Hanoi is metalloid clay, metalloid sand and sand, Alluvia sediments intermittently. Alluvia sediments can be found in lakes and covered with modem sediment with the thickness of 0.5m -6.0 m. The geological structure including layers from up to down as following:

- Layer of mixed clay and mixed clay with mixed sand: This layer is just under cultivate land layer having thickness of 2-1 m. This layer is brown-red, yellow- grey layer of organic mud and sandy mud: This layer has thickness of 10-12m,


12

and it is brown yellow and light brown, high muddy level and low adherent. The bottom of layer is more sandy and average adherent.

- Layer of sand with small cobble: This layer is discovered in depth of 14-18m, its thickness is approximate 15-50m. This layer is grey yellow, mixed with cobble and gravel, average compactness.

- Layer of big granular macadam: This layer has thickness from 50 to 90m, its principal components are cobble, big granular macadam of 5-100mm, with grey yellow sand.

- Layer of clay and sand in surface combines with even and flat terrain. When it is bargain, underground water appears in surface layer. Layer of sand and cobble in depth of 90m is a most abundant hydrated layer. This hydrated layer concerns closely Red river. In West Lake, the height of underground water level is 6m, and thickness of hydrated layer is 6.0 -12m.

2.3.2. Land use

The land use for BRT Component was based on traffic corridors of existing streets of le Van Luong Extension, Le Trong Tan and Quang trung streets therefore the mainly demand of land for this component shall be for proposed BRT stops. However the location of proposed BRT stops will be at the centerline of these existing streets, therefore, no acquired land will be needed for the project. The main dominated land use characteristics

2.3.3. Public Facilities

There are some companies, schools, official building, and residential areas located along two sides of the road. However, this area has been experienced rapidly urbanization, a number of public facilities have also under constructed.

2.3.4 Traffic situation

Intersections on the road

There are about 6 big intersections along the route, see table. However, almost this sections present low traffic volume.

- Grade intersection at the starting point of the realignment project between Khuat Duy Tien and Le Van Luong. This intersection is considered as high potential traffic congestion due to high traffic volume

- High dangerous grade intersection between the proposed route and other residential areas along the route.

Note: Results of air quality monitoring at point of KK04 and KK05 have been taken from EIA report of Ba La – Yen Nghia Extension Subproject under HUTDP

General assessment:

Results from environmental monitoring show that:

- Concentration of CO, SO2 and NOx at three monitoring locations along BRT alignment are still under permission standards QCVN 05: 2009/BTNMT

- Concentration of TSP at three monitoring locations along BRT project exceeded permission standards QCVN 05: 2009/BTNMT, the reasons could be explain for this exceeding is due to surrounding under construction buildings. Both sides of BRT alignment have been experience rapidly urbanization, a several number of urban areas also have been constructing along the Le Van Luong and Le Trong Tan streets which are considered as main air pollution sources in the project area at this time.

- TSP concentration at two last points have exceeded standard about 1.07-2.075 times, the reason could be explained for this result is due to high traffic volume on the road and seriously degradation of road surface.

2.7.2. Noise and vibration

Noise monitoring

- Noisy observation indicators includes Leq, Lamax and L50. The RION Model 2900 (made

in Japan) was applied to measure noise level along the road, and monitoring procedure

complied with TCVN 5964 – 1998, TCVN 5965 – 1995.

General assessment:

The monitoring results show that that noise levels at all monitored locations are exceeded acceptable standard (QCVN 26: 2010). The reason could be explained as three monitoring locations are at main streets with very high traffic volume at the day and night time.

CHAPTER III

ENVIRONMENTAL IMPACT ASSESSMENT

3.1 Potential Impacts Assessment

The project goes on with new construction street, Le Van Luong street, and the main activities of the project are BRT stations, replace surface structure at the stations, installing the concrete separator between BRT and normal lanes, upgrading the existing road surface of Ba La – Yen Nghia section. The project runs within the existing road, and pass through new urban area, which have been experienced rapidly urbanization process. The biodiversity levels were found to be low and there were no rare species. The dominated ecosystem in the area is mixed vacant land, building construction areas. Since, the subproject will not acquire land for the extension purpose, almost construction activities will be within the existing new construction street. According to result of environmental screening, there are not natural, social and historical sensitive objects have been identified along the MRT lanes.

Due to not acquired land for the project, thus most of environmental impacts of BRT will be considered in tow main phases as construction phase and operation phase. The impacts on environmental condition will be assessed through several steps: environmental pollutants will be quantified and calculated, then pollutant concentration in surrounding environmental will be estimated and the impact receivers will be assessed. However, in general assessment the activities of project will not create any seriously impacts on environment in the areas.

3.1.1 Air Pollutant Emission and Impact on Ambient Air Quality

Sources of impacts

- Dust and air pollutants from excavation activities and small concrete mixing machinery

- Activities of material and waste transport vehicle.

- Activities of construction machineries

- Air and noise pollution during operation phase of vehicles

- Garbage from passenger at the station and on the buses.

Impact on Ambient Air Quality - Low negative impact.

a. Construction phase:

Impacts on air quality in the project area associated with construction stage will include a) dust due to the leveling of ground, excavation activities, transporting of construction materials such as earth, stone, cement, sand, gravel etc., b) emissions from equipment and trucks using gasoline, diesel, kerosene, etc., of NOx, CO, SO2, VOC etc. and c) from concrete mixing and


20

asphalt melting stations (if any). However, due to the construction works seem to be very minor, thus the impacts on air quality is considered as quite low.

Dust from leveling of ground, excavation activities:

It is estimated that only around 1303.64 m3 of excavated soil and 522.13 m3 of leveling ground will be needed. The leveling, excavation activities only need for two main items of replacement of road surface in the BRT stop stations and upgrading the existing road surface of Ba La – Yen Nghia section. However, BRT stop stations are located in the separator of the existing streets, Le Van Luong extension and Le Trong Tan, therefore, dust released from this activity will not create any negative impacts on surround areas. Item of upgrading the existing road surface of Ba La – Yen Nghia section, the results from approved EIA report of Ba La – Yen Nghia Extension Subproject and environmental screening show that the section located in the vacant land or under-construction areas of suburban area with high traffic volume, dust from upgrading the existing road surface could cause small impacts on vehicle user on the road and some household, small business shops.

Dust and air pollutants from construction machineries/equipment

Dust and air pollutants from construction machineries/equipment heavy depend on shifts and type of machineries/equipment will be mobilized to the site, however, the construction work of the project will not need more equipment and the surrounding sensitive objects along the route is quite small, therefore, the impact due to air pollutants and noise generated from construction machinery has been assessed as quite small and very short time.

b. Operation period

Although, promotion of BRT route in Hanoi is itself a measure to mitigate air pollution problems. There are still toxic gases and dust emission sources caused by operation of BRT vehicle and BRT flow.

For BRT vehicle, compared to bus diesel, BRT bus emits NOx, CO2, CO, SO2 and PM10 are all lower than in the bus running diesel, shown in the flowing table:

For BRT flow, the amount of dust generated by BRT flow moving on the route depends on composition of type and level of accumulated dust on the pavement. Due to complication and nondetermination of emission source, scope of spreading of those pollutants could not calculated by model. After studying the chemical properties of dirty soil in the road, Clark and colleagues showed that concentration of dirty soil on the road depends on the mode of transport but concentration of parameters of dirty soil are limited as the table 2 below:

Development of BRT network will surely bring about potentials for improvement of air quality in the city, when a certain percentage of motorcycle riders shift to use BRT services. However, according to air monitoring results of route, local air quality at intersections is all higher than national standards by 1.2 to 1.5 times. It is then important to have air quality improvement for operating BRT to ensure emission level is lowest.


22

3.1.2 Noise and vibration

a) Construction phase Noise during the process of construction is mainly from construction machinery, construction transport vehicles and noise from equipment of construction machinery is most disturbing. Construction machinery mainly includes excavator, bulldozer, pavement roller, and mixer and shovel loader. Noise level variation depends on kind of equipment and actual construction activities being undertaken as well as the operating time

Sources: USA Environnemental protection Commette. Noise weight of construction machinery and equipment 300.1, 31 – 12- 1971 In this projects, the machines, will be mobilized to the site, are tamping machine, roller and mixing machine. The experience from environmental supervision activities of several transport infrastructure projects show that, these machines could cause noise and vibration exceeding Vietnam standards (QCVN 26: 2010 and QCVN 27:2010) and at the distance over 20 meter from working areas. Therefore, it can be expected that construction noise and vibration will cause impacts to sensitive receptors within 20 m away from the sites. As the result from environmental screening show that only several HHs located along the Le Trong Tan, Quang Trung streets and Ba La – yen Nghia section are potential impacted by noise from construction activities.

b) Operation phase

With a convenient BRT system, the project expects to convert a big volume of motorcycle riders to BRT riders, and traffic congestions in the city will be prevented. Moreover, BRT helps reduce noise level by:

- Replacing 2 to 3 small buses with a larger vehicle


23

- Using quieter engine technologies - Managing the system to produce “smoother” vehicle operations - Employing noise dampening devices and - Encouraging mode shifting from private vehicle to public transport

According to “BRT Realignment FS Report”, the first year when BRT begin operating, 6.000 passengers per day per one direction estimate. The subsequent years, BRT route receive 20.000 passengers per day per one direction. Capacity per BRT vehicle carries averagely 60 passengers. Therefore, the number of vehicles per hour per two directions is as flowing:

Table 3.4: The number of vehicles per hour per

No Period The number of vehicles per hour per two directions (vehicle per hour)

1 The first year 12 2 The subsequent years 40

Basing on average equivalent noise level of traffic flow under standard condition (table 4), the equivalent noise of the BRT flow is approximately 68 dBA. However, the noise level at a BRT station includes noise generated by all other modes of transport, such as cars, motorcycles and trucks. Moreover, according to environment monitoring result in March 2012, traffic noise in route is higher than the permitted noise level for residential area.

(TDSI, 2005, Integrating Environmental Concerns in Transport Planning) Besides, along the BRT route, there are many building and urban residential area such as Duong Noi, Van Khe urban residential, Park City…. areas are in the process of finishing. When the project goes into operation, the residential buildings and residential areas live fully. Hence, noise mitigation measures are needed for BRT system in addition to other recommendations for environmental impact mitigation. There are two secondary schools and several offices in the both sides of route. However, distance between the centre line of route and schools and offices are quite far as table 5.

3.1.3. Waste Water and impact on water quality

a) Construction phase

The following construction phase activities are known to have direct or indirect impacts on the local water environment:

- Surface water drainage obstructions do ground leveling;

- Operation of construction equipment, construction material transport may cause pollution of surface water due to lubricant oil wastes leakages;

- Establishment of uncontrolled borrow sites next to the road will lead to erosion and suspended sediment entering the watercourse, increasing turbidity levels, as well as being aesthetically/visually unattractive;

- Uncontrolled wastewater from worker camps on the sites.

- Wastewater from maintenance construction machines and equipment

This kind of wastewater contains organic substances, oils and unresolved maters. It is estimated that if equipment maintenance activities have been carried periodically, the supply water volume for each activities as following: i) machine maintenance is 2m3/day; ii) machine cleaner is 5m3/day; iii) machine cool down is 4 m3/day. Due to the very few number of construction machines and equipment are going to mobilize to the site and in the very short time working at the site, thus, maintenance activities intend not carry out at the site, the discharge wastewater from machines and equipment is quite inconsiderable.

- Runoff waster

Rain runoff water will sweep and carry construction material which leading to increase unresolved mater concentration in the watercourses located nearby the sites.

Typically, surface runoff will contain high concentrations of suspended maters, and sometimes leaked oil from construction machinery. And it will leading to increasing concentration of water pollutants such as: SS, COD, oil in the surrounding watercourses. As pointed out by WHO, the pollutant concentration in runoff water will contain about 0.5–1.5mg of N/l; 0.004–0.03mg of P/l; 10–20 mg of COD/l and 10–20mg of TSS/l.


25

In the content of the project, the leveling and excavation activities are quite limited and material storage in the site seen to be so short and small.

- Impact assessment

The receiver objects are watercourse along the route. There are several ponds along the route, all of them are empty or vacant ponds, the rout also pass through 2 rivers, namely La Khe River and Nhue River, however, the water quality of these rivers is serious polluted. In general, the wastewater from project implementation will not cause any significant impacts on surround environment in the area.

b Operation Phase

The main wastewater from operation phase is come from activities of BRT Depot at Yen Nghia terminal. There are two main types of wastewater need to properly control as bellow:

- Domestic wastewater from operator central of Depot, it is assumed that about 20 staffs will be work at the operator central of Depot, the discharged wastewater will be around 700 litters. The domestic wastewater mostly contains food refuse, undissolved matters, organic matters (BOD, COD), Nitơ, Photpho as well as disease virus. According to statistic data for developing countries of WHO (1993), the pollutant loading in wastewater is referred in the below table.

Table 3.7 : Volume of Pollutants in Domestic Wastewater

No. Pollutants Volume (g/person/day)

1 BOD5 45-54 2 COD 72-102 3 Undissolved maters 70-145 4 Oil 10-30 5 Total N 6-12 6 Ammoniac 2.4-4.8 7 Total P 0.8-4.0 8 Total Coliform 106-109

Source: WHO (1993),

And estimated pollutant loading and pollutant concentration in domestic wastewater for both cases of with and without facilitated septic tank is referred in table 3.8.

The calculated results show that concentration of several indicators such as BOD, COD... in the wastewater after treatment by septic tank are still exceed standard of QCVN 14: 2008/BTNMT. Therefore, this kind of wastewater needs to discharge into drain system. - Wastewater from vehicle clean, this kind of wastewater contains organic substances, oils

and unresolved maters. It is estimated that if vehicle clean activities have been carried daily, the supply water volume for each vehicle is 5m3/day, there will be total discharged wastewater for cleaning 50 vehicles is around 250m3/day, which need to be appropriate managed.

3.1.4. Soil waste and its impacts

a) During Construction phase

- Construction waste

Construction wastes including solid, sand, stone which discharged from construction activities. This kind of waste are usually nontoxic and can use for the purpose of fill up for the site of other activities. It is estimated that about 1303.64 m3 of excavated soil will need to be removed from the site to disposal areas.

- Domestic waste and garbage

Domestic waste and garbage is mostly generated from worker camps, and these kinds of waste are organic waste such as: refuse, paper, carton box... and fecal waste. It is estimated that the waste volume per worker per day is around 0,5kg. However, it is planed that no worker camps will be established at the site, the domestic waste and garbage is estimated that very few.


27

- Toxic waste

Toxic waste are mostly oil contaminated waste as regulated in the Circular No. 12/2011-BTNMT dated on 14/04/2011 of MONRE, they are included boxes, cans contain asphalt, petrol, fuels, paints....The volume of this kind of waste depend on the number of mobilized equipment/machines, it is quite difficult to estimate, however, monitoring experiences from a lot of construction sites shows that volume of toxic waste is very few.

- Impact Assessment

According to information offered by the designer, during construction excavation of about 1303.64 m3 earthwork will be generated. This amount of waste will be transported to the landfill site for disposal.

The sanitary waste of constructors, workers includes all kinds of food, official, plastic dishware, cup or bag and other paper, cloth or glass waste commodities. This waste volume need to be properly collected.

Hazardous waste: they include carton box, can, tin contain bitumen, paint and oils. Although, volume of this waste is not much, but they are will cause serious impacts on environment. All kind of waste has to be properly collected, transported and treated in order to avoid the dispersion into surrounding environment.

b) Operation phase

Solid waste will be generated at the stations. The amount of solid waste at the BRT stations will be considerable due to concentration of Passengers and ticket selling staffs. According to “BRT Realignment Design Report”, the first year when BRT begin operating, 6.000 passengers per day per one direction estimate. It means that BRT system operates in the first year, at 12 stations will receive 12.000 passengers per day. Regarding Integrating Environmental Concerns in Transport Planning Report (TDSI, 2005), each passenger at bus stations will generate about 0.03 kg solid waste. Estimating total of domestic waste at 12 BRT stations is as flowing:

Table 3.9: Total estimate volume of solid waste at 12 BRT stations

No. Period Total volume of solid waste (kg) per day 1 The first year 0.03x12.000=360 2 The subsequent years 0.03x40.000=1.200

Besides, there will be a depot will be provided within the existing Yen Nghia terminal, the main functions of this Depot are operator center, fuel refilling station, vehicle storage and vehicle clean area. These activities would daily discharge a small amount of solid waste which need to appropriate management to ensure sanitation condition for whole terminal.


28

However, it is observed that Depot could utilize the existing collection system of Yen Nghia terminal and made some expansion for further requirements.

3.2 Other Environmental Impacts

3.2.1 Ecosystem impacts

The impacts on ecosystem could be due to land encroachment or living environmental effects. Although, the results from field survey see that there no high value ecosystem along the road section, the dominated ecosystem are vacant land or building areas. Beside, most of activities of the project will be constructed overlay on the existing streets, it is considered that the project will not create any negative impacts on eco system in the project area

3.2.2. Impacts of material supply

Due to the material need of the project is quite small, and most of materials are proposed to be purchased, this environmental impact due to material exploitation is not belong to the project.

3.2.3. Traffic safety

a) Construction phase

Due to the construction activities will be taken place at the center lanes of the existing streets, and about. Currently, the traffic volume on the Le Van Luong Extension and Le Trong Tan (Ha Dong) is not quite crowded, however construction activities will add to the road a number of vehicles, machinery and equipment, as well as will temporary encroachment of road surface, which could lead to increase in traffic accident risks for both workers and road users.

The main traffic conflicts need to carefully consideration is on the section on Quang Trung Street and Ba La – Yen Nghia section. The high traffic risks could be listed as i) Ba La intersection with NH 21A, this intersection is considered as high traffic volume and black pot of traffic accident ii) Plain intersection with Bac Hong – Van Dien railway, the trains pass this intersection every day and around 10 -15 times per day, this railway is only support for goods transport between Van Dien and Bac Hong, thus the frequency of trains depending on the goods volume and demand. Therefore, the train schedule is uncertain which may cause several difficulties regarding to safety during construction phase; and iii) intersection with local/community road including the road go to local communities and Thanh Tay university, new planned urban areas and Ho Chi Minh museum; iv) gates of Yen Nghia bus terminal, with 395 passenger cars and 307 buses per day.

The construction activities will add to the road a number of vehicles, machinery and equipment, as well as will temporary encroachment of road surface, which could lead to increase in traffic accident risks for both workers and road users.


29

b) Operation Phase

The project will design pedestrian flyover and bus stops properly and reasonably to ensure that passengers can assess easily and safety.

Due to BRT Depot will be located within the Yen Nghia Terminal, and enter gate will be share for BRT and normal buses which leading to increasing number of vehicle entering and exiting the terminal which create high traffic risks for passenger of the Terminal.

3.2.4. Traffic Flow and Pedestrian

It is also estimated that traffic flow and pedestrian could be affected during the construction phase. The impacts could be included as interrupt the traffic flow and pedestrian, conflicts between construction equipment and traffic vehicle. The high risk points of conflict could be listed as the below table

Chapter IV

PROPOSED MITIGATION MEASURES

The mitigation measures will be proposed in this chapter to reduce the negative impacts and promote positive impacts.

4.1 Construction Phase

4.1.1 Mitigation Measure to Reduce Air Quality impacts

The main objectives of proposed measures are in order to reduce air quality impacts from: i) excavation activities; ii) construction machineries and equipment operation; iii) material transport activities

a. Reduce the impacts due to excavation activities, loading and unloading materials

Excavation and demolition at site will be watered to maintain certain moisture levels, and to prevent or minimize dust from air borne . The watering activities have been proposed at least a time per day during the rainy season and twice a day during the dry season in the working areas. The location need to be watered as in the Quang Trung section and Ba La Yen Nghia Intersection, Depot construction location within Yen Nghia termial.

Reduce dust from construction machinery

- The construction machineries and equipment have to be complied with Decision No. 249/2005/QĐ-TTg dated 10/10/2005 of Prime minister, Regulation on Emission roadmap for road transportation vehicles.

- Regulatory maintenance of vehicles and equipment.

d. Reduce dust from material transportation activities

- The material transportation vehicles have to also be following Decision No. 249/2005/QĐ-TTg dated 10/10/2005 of Prime minister, Regulation on Emission roadmap for road transportation vehicles.

- Required measure for dust control including: covering the transportation means; washing vehicle wheels before leaving construction sites, and transporting with suitable vehicle capacity.


32

4.1.2. Mitigation Measures to Reduce Noise and Vibration Impacts

It is observation at the site, the noise level status in the project area seem to be over allowance standards. The mitigation measures to reduce noise and vibration impacts are proposed as following: a) Appropriate construction schedule, this only apply for the construction activities carry out in the Le Trong Tan (Ha Dong), Quang Trung street

- Priority to mobilize lower noise machines and equipment or facilitating the noise reduction devices and properly maintenance of the equipment.

- Turn off the interrupted machines wherever possible to avoid resonant frequency.

- Use of machines generate noise level over >55 dBA at night (from 22:00 to 6:00) will be strictly forbidden and other noisy activities including heavy truck transportation, loading/unloading, beam lifting and stockpile of the materials will be carried out during the day time.

b) Use the construction equipment with lower noise

Use the construction equipments with lower noise as much as possible during construction; It is expected that if all kind of construction equipments will be lower noise, the noise level reduction could be obtained from 6 dBA to 12 dBA.

Therefore, use the construction equipments with lower noise, the noise level in the resident areas could be within the standard.

Conclusion, in order to reduce the noise impacts in the construction phase from this subproject, the following measures will be taken together for noise control

4.1.3 Mitigation Measures of Water Environment Impacts

o Storage of fuel, chemical substances, paint shall be sited on an roofed areas. Filling and refueling activities have to carry out within and secured by fencing to avoid the leaking out in the environment. .

o On the site, the wastewater from machine maintenance activities will not discharge directly into any watercourse. The collected oil will be deposited in a tank and treated according to Circular No. 12/2011/TT-BTNMT dated 14/04/2011 of MONRE.

4.1.4. Solid Waste Management

- Construction waste: Construction waste will be transported to the disposal site about 25 km far from Hanoi, the location of waste disposal will be clarified and survey during detail design. - Domestic waste:


33

The domestic waste will be collected as following steps: i) collect at sources; ii) waste divided for reuse; iii) transport and treat properly through an economic contract with Hanoi URENCO. To collect waste at source, garbage cans will be provided at the site.

- Oil related waste They include waste oil from machines, equipment maintenance will be collected, transported and treated properly through an economic contract with Hanoi URENCO, according Circular No. 12/2011/TT-BTNMT dated 14/4/2011 by MONRE.

- Site clearance since construction activities completed

After the construction activities completed, contractors have to carry out site clearance and environmental recovery, such as:

- Transport all unused materials to ensure that the construction activities will not cause any encroachments to surrounding environments;

- Remove all construction machine and equipment, temporary facilities, worksites; - Environmental recovery at the site such as provision of green trees, grass…

4.1.5. Asphalt and hot-mix plant

The concrete for project will be purchased from 2 nearby concrete and asphalt and hot-mix plants, to ensure the environmental protection, the contractors and PMU Hanoi need to check the environmental certification if these plants. The environmental protection requirements will be both aspects of documents and practice on the plants.

4.1.6. Mitigation Measures to Flora and Vegetable Impacts

The following mitigation will be taken during construction: - The green belt occupied in the construction phase will be restored when the

construction is finished. - All construction activities will be carry out within the site boundary

4.1.7. Mitigation measure to reduce traffic congestion and accident

- Provision the traffic signs at the both side of working sites and at main intersections to require vehicles to reduce their speed..

- Also provision the note sign at the sites and in gate way of companies, factories, universities, officers…..

- Avoiding the occupation of street surface during the rush hours;

- Utilizing nighttime to carry out construction activities in the section away from resident areas.

4.2. Operation Phases

4.2.1. Air quality


34

From 2007, all types of on road vehicles must be comply with Vietnam national emission standard (equivalent to EURO 2 standards), and Vietnam government has also set up roadmap for EURO4 and EURO5 application as the big efforts to control pollution from transport means. Therefore, BRT vehicles in the project must be comply with Vietnam National emission standard.

- Periodically road surface sanitation and public awareness raising actions would be taken place for the purpose of air quality maintain. Moreover, the maintenance of road surface, bridge periodically is to limit the getting old asphalt.

- Tree should be planted on the both sides of the road for prevention of dust and reduction of noise for house and building along side.

4.2.2. Noise

To reduce noise level, BRT buses will need periodic maintenance. Bus drivers should restrict horning in areas close to schools, offices, buildings and resident areas at km 0+700; km 0+900; km 1+400; km 7+200. With the specifically designed double glazed noise isolation windows, the noise levels are expected to reduce by about 25-28 dB(A). Those sensitive receptors for which such windows will be installed, the indoor noise levels will be reduced to below the applicable standards and the residual impacts will be insignificant and acceptable. Developing of green belt on the both sides of the road will reduce noise levels in future and avoiding planning new sensitive receptors near route.

4.2.3. Solid wastes

The waste storage bins shall be located at BRT stations. Waste bins shall be designed with different colors for keeping the nice aesthetics. The collection and treatment methods for this solid waste shall be done by Hanoi URENCO under assigned and management of TUPWS.

4.2.4. Wastewater control

Appropriate system need to propose to collect, treatment wastewater from Depot’s activities, as bellowing


35

- Detail information The wastewater discharge and treatment will be divided into three main flows. + Flow 1: Runoff water (rainy water): this kind of wastewater is considered as polluted

and could directly discharge into general drainage system, however a grille must be provided at the gate of drainage to control garbage and waste enter the flow

+ Flow 2: Domestic wastewater: this kind of wastewater must discharge into septic tank before discharging into general drainage system of Yen Nghia Terminal;

+ Flow 3: Vehicle maintain and clean wastewater: this kind of wastewater must collect into a technical hole (pond) for primary treatment includes depositing unresolved maters and collecting oil spill before discharging into general drainage system of Yen Nghia Terminal
