CHAPTER 1. INTRODUCTION AND BRIEF PROJECT DESCRIPTION
1.1. BACKGROUND AND PROJECT OBJECTIVES
1.1.1. Background
Phu Ly City is the political, economic and cultural center of Ha Nam province. It is
located about 50 km south of Hanoi, on the main north south railway and national highway
1A, which is ultimately lead to Ho Chi Minh City. The city is presently small, consisting
essentially of an old urban area clustered along both banks of the Chau Giang River.
However, as Hanoi expands, and transport links between the capital and the south improve –
an expressway is under construction and a high-speed rail link is being studied – Phu Ly will
inevitably become a satellite city for Hanoi.
In recent years, Phu Ly city has been developing continuously in its economy, politics,
society and culture. The technical and social infrastructure has also been improving
progressively. Nevertheless, the city is still struggling to keep up with rising demand for basic
urban infrastructure including traffic systems, drainage and environmental sanitation systems,
water supply systems, etc. To address these issues as well as to support its role and functions
in the socio-economic development of the provincial and the wider northern region of the
country, the city has prepared a master plan towards 2020 which has been approved by Ha
Nam Provincial People’s Committee.
Ha Nam Provincial People’s Committee (PPCs), which is responsible for Phu Ly City,
has requested World Bank (WB) support for essential infrastructure under the proposed
Medium Cities Development Project (MCDP, or “the Project”).
The Project will finance multi-sector infrastructure investments in Phu Ly responding to
infrastructure deficits and urban services demands as expressed through the city’s master
plan. Specifically, the project will support infrastructure rehabilitation and improvement in
the old part of the city, and new infrastructure in the new urban area into which the city will
expand. The investments include surfacing existing roads and lanes in selected urban areas;
extending water supply and drainage networks and linking the latter to a new wastewater
plant, also to be constructed under the project; and expanding and improving several small
lakes that will become part of the city’s green space while also serving an important flood
mitigation and retention purpose. In the new urban area, the project will finance construction
of a core access road, with a bridge across the Chau Giang River that will provide a strong
connection between the northern and southern parts of the city. The road will be incorporate
water supply and drainage/wastewater pipe networks within its corridor, the latter connecting
to the project-financed wastewater plant that is to be constructed in the northwest of the
expanded city area.
The project will also support the city with implementing the project, with developing a
more comprehensive and appropriate approach to urban planning, and with developing the
capacity to manage its expanding infrastructure assets.
1.1.2. Project objectives
Short term objective
- Improve and raise the living conditions of low-income residents in the project area.
VIWASE-OCI Consulting Association 2
- Enhance the capacity for rainwater drainage, wastewater collection and treatment;
improving the hygienic and environmental conditions; provide clean water to improve
people’s living conditions, contribute to comprehensive infrastructure development,
and meet the overall development requirements of the city
- Rehabilitate degraded roads and construct new inter-ward and inter-commune roads,
thus contributing to socio-economic development
- Construct main roads and urban bridges as planned to facilitate a dynamic urban

Long term objective
- Develop Phu Ly City into a big urban area, economic center spearheading the growth
to meet socio-economic development objectives of Ha Nam Province; a motivation
for the economic development in the whole southern area of the northern Delta.
- Invest in construction to create the technical infrastructure framework in accordance
with Phu Ly City Master Plan towards 2020, thereby attracting investors to the city,
create a momentum to promote economic development of the city to make it perfect
and become a satellite city to Hanoi Capital.

Other potential social impacts and mitigation measures on local communities such as those relating
to transportation, road safety or public safety, or disruptions of communities during site clearance,
construction, and operation are integrated into the discussion in Sections 4.3.
4.2.3 Potential Impacts on Physical Cultural Resources (PCR)
– Besides the relocation of individual graves (326 graves in total), implementation of the Phu Ly
subproject will not involve any impact on any known PCR. The mitigation measures for grave
relocation, including relocation cost, are covered in the project RP
4.2.4 Cumulative Impacts
The MCDP three subproject cities are located in different geographical areas and provinces
within Vietnam. No cumulative impacts between the three cities, subprojects and other
associated subprojects are anticipated because of the geographical distance and the types and
limited scales of investment activities.
As for Phu Ly city, cumulative negative impacts might have occurred in the case of a subproject
activity causing significant negative impacts that add in a measurable and significant way to
those that are being caused by nearby projects or by projects that take place in the same area,
either before or after in time. Except the linkage with the WWTP being funded by BTC, the Phu
Ly subproject EIA has however not identified any cumulative negative impacts. This is due to
the small scale of most works, the type of works, and their location. As for the connection with
the BTC WWTP, receiving waters for wastewater discharges from the BTC WWTP may receive
other discharges from the city wastewater treatment networks. However, these discharges will
replace untreated wastewater now being discharged into the same stream so the cumulative
impacts will be positive.
Nevertheless, due diligence review of the EIA report for the BTC WWTP was conducted to
assess the level of additional impacts resulting from the Phu Ly subproject investment, as well as
the adequacy of the EA work carried out for the WWTP. The assessment considered maximum
design capacity, discharge of effluents and sludge management during operations, outcomes of
public consultation and the EIA approval provided by DONREs. Although the EIAs were
prepared and approved in 2007, they are still valid as no changes in the design and
environmental settings are envisaged. Specifically, the design capacity is 5,000 m3 is adequate
for accepting wastewater from all population living in the catchment which covers the downtown
area, Liem Chinh and Liem Trung communes and this is wider than the WB project area. Public
consultation in these areas was conducted sufficiently with the commune people committees and
the local Fatherland front as required by the GOV regulations. The selected technology provides
treatment of sludge generated during WWTP operation and the final disposal will be arranged
with URENCO at the city sanitary landfill. Effluents will be discharged to Day river, in the
downstream of the water supply intake on Day river. The EIA report was approved by Ha Nam
provincial People Committee, based on recommendation of DONRE, on August 2, 2007. Based
on this assessment, it is concluded that the anticipated cumulative impacts will be within
environmental thresholds and therefore special mitigation measures will not be required.

The various urban investments to be financed under the project, producing for the most part
minor and temporary impacts such as noise, dust, and traffic disturbances, or positive impacts
such as improved local water quality or accessibility will be a small part of much larger and
long-term urban development initiatives that are being implemented under the city’s urban
master plan. These city plans have each assessed and taken into account long-term effects, both
adverse and positive, of the proposed urban development plan with their infrastructures and
considers these investments will result and bring about positive environmental changes in the
cities. The proposed urban development plan was reviewed and considered to adequate reflect
long-term impacts of which the Phu Ly subproject infrastructure investments are a very small
part with no cumulative impacts.
4.3 DETAILED ASSESSMENT OF ENVIRONMENTAL IMPACTS
The Phu Ly City subproject comprises four basic infrastructure to be carried out in old city
areas (Quang Trung ward, Hoa Lac village, and Me Noi village); five water supply and sanitation
to be carried out in semi-rural areas; and one new road (D4-N7) and one new bridge (Chau Giang
Bridge) to be carried out mostly along existing flat land mainly used for rice field. The old town
areas are highly populated with narrow roads and the key activities will include upgrading of
existing roads and installation of water supply and/or drainage networks. Data on water quality,
soil/sediment quality, air, noise, vibration, and other environmental condition suggested that water
quality and sanitary condition in old urban area (especially Quang Trung ward) and rivers (Nhue
River, Chau Giang River) show sign of pollution. The text below looks in more detail at key
project environmental impacts during preconstruction, construction, and operation phases, as
required by Vietnamese regulations for EIAs.
4.3.1 Impacts due to Construction of Infrastructure in Quang Trung Ward
Quang Trung ward is located about 2.7-3.5 m from the Nhue River dyke and is
underdeveloped. Most of the internal roads are dirt road or gravel roads (2-3 m wide) and many are
deteriorated seriously. Population is about 2,868 (696 households) with limited public services.
The project will be located in the northern part of Quang Trung ward on an area of about 55 ha.
Works include (a) construction of a main internal road (0.9 m long, 9.5 m wide) to connect to
outside network by expanding existing dirt roads to asphalt road, including improve landscaping;
(b) installation of storm water drainage network (0.9km) along the newly built road with about 696
households connections of which 42 septic tanks will be installed by the project for poor
households; and (c) installation of water supply network (5 km). Activities will include ground
leveling, excavation and backfilling for foundation, construction of road subbase, culver, etc. Key
potential impacts are discussed below.
Construction wastes and transportation
– House demolition and generation of air, noise, and vibration, and disturbance to local residents
are expected to be the key impacts of the subcomponent. It is estimated that about 1,650 m3 of
construction waste (house mantling and tree clearance) will be generated and these wastes will
be disposed off at the Thung Ham landfill which are located about 15 km from the construction
VIWASE – LAVIC Consulting Association
63
site. Increasing transportation volume will increase the level of air, noise, and vibration, and
road safety, however, these impacts will be moderate, localized, and temporary and can be
mitigated through good transportation practices. Moreover, demolition activities can increase
safety risk to worker as well as the general public and it should be carefully carried out during
demolition and transportation. Given that the area is highly populated road safety issues will be
important.
– The contractor should be required to ensure that safety risk and mitigation measures for
reduction of air, noise, vibration, and road safety risk are in place before starting construction.
Air, noise, vibration
– Air pollution, noise, and vibration will also be important since high concentration can cause
disturbance and health impacts to local residents. However, this impact will be temporary,
localized, and can be mitigated. Loading and unloading of materials, operation of heavy
equipment and machines, and transportation of waste and materials are the major sources and
generation of air, noise, and vibration from these activities will have to be strictly controlled as
much as possible. Specific attention should be given to minimize the impacts during
construction of the main internal road.
Local flooding
– Construction of embankment across a flat land could change the water flow pattern in the
project and nearby area both during construction and operation phases. During detailed design,
attention should be given to ensure adequate drainage is provided and consultation with local
community is carried out.
Other impacts
– Other impacts would include generation of solid and liquid wastes from workers,
sedimentation and possible discharge of hazardous materials (mostly oil/grease) from
construction sites. These impacts are expected to be low given the localized nature of the
activities and small number of worker to be involved. For the overall component 1, it was
estimated that about 5 kg/month of hazardous waste (used oil/grease, used battery, fluorescent
lamps, etc.) and about 150 workers will be required (about 10 m3/day of wastewater and 90
kg/day of solid). Some of these wastes could be collected and recycled and the rest could be
managed by URENCO.
4.3.2 Impacts due to Constructions of Infrastructure in Hoa Lac Village
– Hoa Lac village belong to Lam Ha commune which is located in the northern part of Chau
Giang basin. This is an old town with small narrow roads (mostly dirt and gravel roads) and
limited water supply services. The project area is about 110 ha with 1,274 people.
– Works include (a) upgrading of existing roads to concrete roads (2m-3m wide, 2.1 km); (b)
installing a storm water and drainage network (2.7 km) along the upgrading roads, and (c)
installing water supply network (4.2 km long, D125-D32) along the existing roads and the
residential area.
VIWASE – LAVIC Consulting Association

– These works are small they will be implemented at different locations and all typical impacts
i.e. increasing air, noise, vibration, waster pollution, wastes, and disturbance to local resident
can be mitigated through good construction practices. However, given that the activities will be
carried out in residential area, specific attention should be given to reduce the risk due to road
safety during construction.
4.3.3 Impacts due to Constructions of Infrastructure in Me Noi Village
– Me Noi village belong to Liem Chinh commune which is located in the southern part of Chau
Giang River. This is an old town with small narrow roads (mostly dirt and gravel roads) and
limited water supply services. The project area is about 81 ha with 1,392 people.
– Works will include (a) upgrading of existing roads to concrete roads (2m-3m wide, 0.8km
long); (b) installing a storm water and drainage network along the upgrading roads (1.3 km,
D400-D600); and (c) installing water supply network (D125-D32, 6.1 km) along the existing
roads and residential areas.
– These works are small they will be implemented at different locations and all typical impacts
i.e. increasing air, noise, vibration, waster pollution, wastes, and disturbance to local resident
can be mitigated through good construction practices. However, given that the activities will be
carried out in residential area, specific attention should be given to reduce the risk due to road
safety during construction.
4.3.4 Impacts due to Constructions of Schools in Quang Trung Ward
– Two schools will be built in Quang Traung ward. Works will include construction of (a) a
primary school (12 rooms, 425 pupils, 580 m2) and (b) a kindergarten (9 rooms, 350 pupils,
1,136 m2). The project site will be located near Lac Trang Pagoda.
– Works will be small and short period and the impacts during construction will be limited to
increasing air, noise, and vibration during construction while impacts during operation will be
limited to poor utilization and maintenance of toilet and sanitation facilities that may generate
bad odor and unsanitary condition. Potential impacts on the nearby Pagoda would be unlikely
since the construction site will be located about 500 m far way form the Pagoda structure and
activities. However, given that the activities will be carried out in residential area, specific
attention should be given to reduce the risk due to road safety during construction. The
contractor should also be required to avoid disruption and/or disturbance to the nearby pagoda
and a chance finds procedure will be included in the contract.
4.3.5 Impacts due to Constructions of Regulating Lakes in Lam Ha and Quang Trung
Lam Ha Lake (14.7 ha) is located in Lam Ha commune and comprises two lakes connecting to
each other. Quang Trung Lake (2.5 ha) is located in Quang Trung ward. These areas are part of
the old town with small narrow roads (mostly dirt and gravel roads) and limited water supply
services. Construction works will include (a) excavation, dredging, and revetment of the lakes;
VIWASE – LAVIC Consulting Association
65
(b) building surrounding roads; installing water drainage around the lakes; and (c) installing
lighting. Key potential impacts are discussed below.
Odor, noise, vibration
During construction, about 121,764 m3 of dredge materials will be excavated (14% from Quang
Trung (2.5 ha), 40% from Lam Ha 1 (7.3 ha), 42% from Lam Ha 2 (7.5 ha), and 0.4% from
existing drainage. Some of these materials are contaminated with organic and inorganic contents
(including heavy metals). Dredging and transportation of sediment contaminated with organic
content could generate foul odor and unsanitary condition during storage, transportation, and/or
disposal. Analysis of bottom sediment undertaken during the EIA study suggested water quality
in the lakes appears to be better than those of the nearby Nhue River and Chau Giang River and
the level of heavy metals in the lakes remains within the standards. However, to avoid potential
adverse impacts due to contamination of hazardous materials during dredging, transportation,
and disposal of bottom sediments, a Dredge Materials Management Plan (DMMP) will be
prepared during detailed design and implemented. The DMMP describes (a) detailed estimate on
the nature and quantity of dredged materials, (b) chemical analysis for heavy metals of the
dredged materials, (c) indicative dredging, transportation, and disposal methods, and (d)
communication plan with local residents to ensure that the proposed mitigate measures are
acceptable. Before dredging and construction the contractor will be required to propose specific
mitigation measures through the preparation of site-specific environmental management plan.
Water quality
– Water at the bottom of reservoir: before dredging, the construction unit will drain the water
off and then equipment is used for dredging and banking. It is estimated that water pumped
out of Quang Trung, Lam Ha 1 and 2 regulating reservoirs would be 25,000 m3 for Quang
Trung, 75,000 m3 from Lam Ha 1, and 76,000 m3 for Lam Ha 2. Analysis suggested that
current water quality in these lakes is generally better or similar compared to surface water in
the Nhue and Chau Giang River. However, pumping of the water (from Quang Trung Lake
into Nhue River and Lam Ha Lake into Chau Giang River) will at least increase amount of
suspended solid in the water column and this may affect other water users as well as fishes
and aquatic life. Therefore, mitigation measures will be necessary to minimize the impacts.
– Impacts during operation are expected to be minor. Quang Trung Lake (2.47 ha) has been
designed as a regulating lake. When the level higher than 2.5m, water will overflow to the
Nhue River or will be pumped out. Analysis of water sample during the EIA study suggested
that the water quality of Quang Trung Lake is at B1 level which is better than that of Nhue
River. It is unlikely that water quality of Nhue will be adversely affected.
Other impacts
– Generation of domestic wastes, hazardous wastes are expected to be small. These may
include Sources of hazardous wastes generated during this stage are mainly waste oil and
grease; the generation of such waste oil and grease during maintenance and repair of
VIWASE – LAVIC Consulting Association
66
dredging equipments, transportation vehicles, and construction machines is inevitable.
Average volume of waste oil and grease generated by mechanical means is 18
liters/lubrication. Routine lubrication and maintenance for machines and equipments is
implemented every 3-6 months; it depends on operating frequencies of construction
machines and equipments. As estimated, the number of construction machines and
transportation vehicles at construction sites is 20-40. Therefore, the volume of waste oil and
grease is estimated 120 - 140 liters/month.
4.3.6 Impacts due to Constructions of Wastewater Network for Chau Giang and Water
Transmission Line along Road D4-N7, including Two Pumping Stations
Works will include construction of a separate sewer system for wastewater collection (D315-
D900, 7.3 km) for Chau Giang area and the main water supply transmission line (DN100-
DN300, 6.1 km) along D4-N7 Road, including two pumping stations (1,970 m3/day and 2,700
m3/day).
Key impacts would be limited to increasing air, noise, vibration, and possible bad odor emission
during operation and they are discussed below.
Air, noise, vibration
– This works will be carried out at the same time as the construction of D4-N7 Road and
significant impacts is not expected. Potential impacts during excavation and installation of
the pipeline and manholes will be located within the road boundary and additional impacts
will be limited to increasing dust, noise, and vibration, however they will be small,
temporary, and localized. However, to ensure that good construction practice is applied by
contractor, specific environmental requirements will be included in the contract.
– Construction of the two pumping stations will also be limited within the road right of ways.
This is a small works and the potential impacts (air, noise, etc.) will be limited during
construction. Good construction practice will be applied to avoid potential impacts on local
residents.
– Odor: During operation, operation of the pumping stations and dredging of manholes may
create bad odor and increase disturbance to local residents. Care should be carried out to
minimize possible impacts during transportation and disposal. Effort will be made to ensure
effective operation and maintenance of the facilities, including budget.
Other impacts
– Other impacts related to soil, wastes generation and disturbance to local residents will be
small and mitigation will be incorporated into the specific environmental requirement for
contractor.
VIWASE – LAVIC Consulting Association
67
4.3.7 Impacts due to Construction of Pumping Station for Quang Trung Regulating Lake
– The station will be built to pump (8,000 m3/hr) flood water from Quan Trung Lake to Nhue
River. Works will include installation of two booster pumps at each capacity of 4,000 m3/hr.
The stations will be located on the public land.
Impacts during construction
– This is a small civil works and the key potential impacts would be limited to increasing air,
noise, and vibration, however they would be small, temporary, localized. Direct discharge of
solid and liquid wastes (including oil/grease) from the construction site and/or workers to the
nearby environment and the river (Nhue River) may also occur however the risk will be
small and can be managed. Good construction practice will be applied to avoid potential
impacts on local residents.
Impacts during operation
– During operation, access rainwater will be discharged into Nhue River, but poor operation
and maintenance of the pump and station could cause local flood in the areas and possible
contamination of polluted water (especially those contaminated with oil/grease). Appropriate
operation manual for the puming station should be in place, staff trained, and adequate
budget should be provided by the city.
4.3.8 Impacts due to Construction of Chau Giang Wastewater Treatment Plant (WWTP)
Construction of the Chau Giang WWPT (3,000 m3/day) will be carried out on an area of 3.2 ha
being used for rice field. The WWTP has been designed to treat wastewater according to the
standard QCVN 24:2009/BTNMT. The treated wastewater will be discharged into an existing
irrigation canal (A46). The discharge point is about 2.8km before reaching the Chau Giang
River. Key potential impacts are discussed below.
Air, noise, vibration
– During ground leveling and construction about 4,500 m3 of soil/mud will be excavated and
disposed of at Thung Ham landfill which is located about 15 km from the construction site.
This will increase in traffic volume and the level of air, noise, and vibration in the project
area and possible disturbance to local residents. However, given that the proposed area is a
large open space and is quite far away from residential area, the impacts could be managed.
Good construction and transportation practices will be applied and this requirement can be
incorporated as part of the construction contract.
– During operation of the WWTP, the impacts on odor, noise, and vibration ion local residents
and environment will be small.
Water quality
VIWASE – LAVIC Consulting Association
68
– The proposed construction site is located near the existing irrigation canal (Area No.46).
Therefore during site clearance and construction, especially during rainy season, sediment-
ridden water (especially with oil/grease) can be discharged into the irrigation canal and
affecting the framers, water quality, fishes, and aquatic life. Moreover, when excavated soil,
and/or solid/construction wastes are not properly stored, covered, and/or immediately
transported out of the construction sites, or is spilled and/or scattered during transportation,
rains could wash them down and increase water pollution. Waste oil and wastes from
workers at construction site could also be a source of impact on surface water quality
however this impact is generally small and could be mitigated on site. Most workers in
urban area are temporary workers who are from the local community and they will return to
their own homes after working hours. However, it is necessary to arrange for temporary
sanitation facilities and daily solid waste collection.
– During operation, the Chau Giang WWTP (3,000 m3/day) will discharge its treated
wastewater into the A46 irrigation channel, therefore operation of the WWTP may affect
water quality in the receiving water, especially if it does not operated and maintain properly.
Currently, A46 irrigation channel is the main channel providing water for approx. 1,000 ha of
agricultural land for paddy fields of Tien Hai and Tien Hiep Communes. The flow and the
quality of water of this irrigation channel meet the demands of agricultural irrigation
activities. However, if this channel receives an additional amount of 3,000 m3 /day of treated
wastewater, the flow of the channel will be increased to about 0.035m3/s. In dry seasons, this
additional water could be considered as beneficial, however the water quality have to be
checked to avoid impacts to the existing water users. Given that the WWTP has been
designed to treat wastewater according to the standard QCVN 24:2009/BTNMT, the impacts
on surface water of the A46 are considered low under normal operation. In initial assessment
was conducted for emergency events when wastewater is discharged without treatment.
– In case of operation failure, or power black-out causing temporary stop in operation of
WWTP, about 3,000 m3 of untreated wastewater will be discharged directly into the
irrigation area. However, given small wastewater volume compared to the water flow in the
irrigation area and Chau Giang River, adverse impacts are not expected. Nevertheless, to
reduce the risk it is following actions should be carried out: (a) ensure effective operation of
the WWTP according to the treatment standard and (b) monitor water quality along the
irrigation canal and establish/maintain close consultation with the farmers along the 2.8 km
distance of the A46 irrigation canal who may be affected by the water quality.
Other impact
– During operation of the WWTP, disposal of treatment sludge will be the key issue. It is
estimated that about 300 kg/day (110 tons/year) of sludge will be generated and they will be
transported and disposed of at the existing sanitary landfill. Generation of other solid waste
can also be managed.

4.3.9 Impacts due to Construction of Road D4-N7 and Chau Giang River Bridge
Construction of D4-N7 (4 lanes, 4.74 km long) and Chau Giang Bridge (4 lanes, 195 m) will be
carried out in the same area and is connected to each other so the impact assessment is made
together. Construction of D4-N7 road (about 4 km) will be carried out on a flat land mainly used
for rice field while about 0.7 km cut through the residential area in Me Noi Hamlet. Land
acquisition will be made for a 68 road width however the pavement width to be constructed
under the project would be about 14 m and the road base will be filled with soil. Construction of
the Chau Giang Bridge will be made with pre-stress reinforce concrete and with asphalt
surfacing and serve both vehicles and pedestrian. Key potential impacts are discussed below.
Construction waste and fill
– During site clearance, about 0.5 m-deep of organic soil layer will be removed and thus
generate about 200,000 m3 of organic soil (equivalent to 400,000 tons) that require disposal.
House dismantling and tree clearance will generate an amount of about 3000 m3 of waste.
Experience in the country suggests that nearly 80% of these wastes (bricks, tiles, wood, etc.)
will be recycled and reused.
– During construction, about 10,048 m3 of soil, stone, and asphalt would be purchased from
Kim Bank and Thanh Liem (located about 13-15 km from the site); sand will be transported
from the Red River. Sourcing of all borrow material will be subject to the environmental
provisions of the EMP.
Air, noise, vibration
– During site clearance, dust and gases emission will be generated from heavy machine and
equipment. These impacts will be localized, temporary and are considered minor and can be
mitigated through implementation of dust suppression methods and suitable planning of
construction activities. Noise and vibration is likely to be generated and these impacts are
likely to be localized and temporary minor and easily mitigated through maintenance of
construction equipment and appropriate scheduling of construction works.
– During construction, there will be a number of noise pollution sources due to operations of
many types of machines and engines however the noise level is difference for different
machines and the workers on construction sites will be mostly affected because they will be
working in the nearest proximity to the source of noise emission. Households in the area
within 200 m from emission source can be affected by noise however, the impact would not
be high and is temporary. The contractor will be required to take measures to reduce noise
during construction.
– Auger drilling during construction of bridge pier will cause temporary impacts to the quality
of surface water in Chau Giang River. Because the scale of construction is not large, number
of drilled holes is not high and construction time is short, the impact on surface water quality
during bridge construction is only in small scale and for short time. In the drilling process,
VIWASE – LAVIC Consulting Association
70
steel pipes are installed immediately along with the movement of driller; bentonite drilling
mud is not used; and drilling scale is not large. Therefore, the environmental impact to
groundwater is virtually nonexistent or negligible.
– Most of the workers on the construction site are seasonal workers; they live within the city or
in the surrounding areas. Small numbers may temporarily stay at the construction sites in
tents, or temporary housings. The provisions of the EMP ECOPs regarding management of
solid and domestic waste at the construction site will have to be carefully followed.
Other wastes
– A large solid waste such as soil, stones, construction materials, cement and steel scrap will be
generated during construction. Therefore, it is necessary to have appropriate management
measures at the construction site to avoid dispersion of solid waste into the surrounding
environment.
– Oil and grease: Construction of D4-N7 Road and Chau Giang Bridge will also generate
oil/grease mainly from used engine and machinery lubricant oil, especially from trucks
transporting construction materials. It was estimated that an average amount of used oil from
a construction machine is about 3-7 liters after each oil replacement for the time period of 3-4
months. Due to large workload, the number of construction machines used in the same period
may be large, leading to a significant volume of used oil. Therefore, during construction, it is
required to apply strict management measures to limit dispersion of used oil on the
construction site and ensure effective management on site.
Labor Safety
Accidents at work during road and bridge construction happen due to: untrained project
manager and other workers on work safety; Not equipping worker with safety working
means; Workers not following labor safety regulations; Lacking management by project
manager during construction; During construction, the contractor should pay attention to
labor safety issue in order to reduce the risk of labor accidents as outlined in the ECOPs.

CHAPTER 5. PROPOSED MITIGATION MEASURES
Several strategies (avoidance, minimization, rectification, and/or compensation) have been applied
to mitigate the potential negative impacts identified in Chapter 4. In developing the mitigation
measures, the strategies to minimize and/or rectify the impacts have been applied and where
appropriate compensation has been incorporated. The proposed mitigation measures to reduce the
impacts due to land acquisition and resettlement are described in the Resettlement Plan (RP).
This chapter identifies mitigation measures of the key project impacts during construction (which
include site clearance, ground leveling, construction, and site restoration) and operation phases.
Given that most of the key impacts will occur due to civil works and transportation of
construction/waste materials, many of the potential negative impacts on physical, biological, and
social environment could be mitigated through a set of generic measures that are typically applied
to most of construction projects to minimize impacts such as noise, dust, water, waste, etc. As part
of the Environmental Management Plan (EMP) for the project these generic measures have been
translated into a standard environmental specification to be included (as an annex) to the
construction contract, namely the Environmental Codes of Practice (ECOPs) and it will be applied
to mitigate typical impacts of small civil works. Section 5.1 briefly explains scope and content of
the ECOPs (see Chapter 6).
However, for Phu Ly city subproject there are site-specific impacts that require site-specific
measures both during construction and operation stages. Section 5.2 identifies site-specific
measures during construction for the subcomponents that require mitigation measures beyond
those identified in ECOPs. Section 5.3 identifies site-specific measures to mitigate impacts of the
key subcomponents during operation phase. These measures are incorporated into the EMP of the
project (Chapter 6).
5.1 MEASURES TO MITIGATE GENERIC IMPACTS DURING CONSTRUCTION1
ECOPs describe typical requirements to be undertaken by contractor and supervised by the
construction supervision engineer during construction. The final ECOPs will be included as an
annex in the bidding and contract documents (BD/CD) during detailed design stage and the
bidder will be formally informed during the bidding. Scope and content of the ECOPs is as
follows:
Scope: Construction activities for small works governed by these ECOPs are those whose
impacts are of limited extent, temporary and reversible, and readily managed with good
construction practices (see Chapter 6 for the main content of the ECOPs; the full ECOPs are in
an annex.
1 This include site clearance, ground leveling, construction, and site restoration
VIWASE – LAVIC Consulting Association
72
The mitigation measures described in the ECOPs are considered adequate for mitigation of most
of the potential impacts during construction. In this context, the ECOPs will be applied to the
following subprojects and this will be reflected in the EMP (Chapter 6).
Subcomponent
1.2 Construction of Infrastructure in Hoa Lac Village
1.3 Construction of Infrastructure in Me Noi Village
1.4 Construction of Schools in Quang Trung Ward
2.2 Construction of Wastewater Network for Bac Chau Giang and Water
Transmission Line along Road D4-N7
2.3 Construction of Wastewater Pumping Stations
2.4 Construction of Pumping Station for Quang Trung Regulating Lake
2.5 Construction of Chau Giang Wastewater Treatment Plant
5.2 MEASURES TO MITIGATE SITE-SPECIFIC IMPACTS DURING
CONSTRUCTION
5.2.1 Site-Specific Measures for Construction of Infrastructure in Quang Trung Ward
Potential impacts of the subcomponent are considered moderate, temporary, and localized and
most of them can be mitigated through the typical mitigation measures identified in ECOPs. Key
site-specific impacts include safety risk, important quantities of demolition of houses along the 0.9
km central road to be constructed, and potential local flooding in adjacent areas. To mitigate these
impacts the following measures will be carried out by the PMU:
– During construction, the contractor will be required to ensure that demolition of houses
along the central road to be constructed in the site is carried out safely in accordance with
the contract conditions.
– During detailed design, PMU will ensure that detailed design will provide adequate
drainage to avoid potential flooding during construction and operation.
5.2.2 Site-specific Measures for Construction of Regulating Lakes in Lam Ha and Quang
Trung
Potential impacts of the subcomponent are considered moderate, temporary, and localized and
most of them can be mitigated through the typical mitigation measures identified in ECOPs. Key
site-specific impacts include (a) odor and other contamination resulting from the excavation,
transport, and disposal of approximately 70,000m3 of wet sludge with a high organic and some
heavy metal content, and (c) damage to partly completed works by flood. To mitigate these
impacts the following measures will be carried out by PMU:
VIWASE – LAVIC Consulting Association
73
– Ensure that the detailed design for the lake works explicitly provides for all aspects of the
sludge management process: excavation, transport in leak proof and covered trucks, and
deposit into suitably prepared sites (landfills for material that testing shows is not
contaminated beyond specified limits, and prepared sanitary landfills – for example the
existing sanitary landfill at Thung Ham – for material that is contaminated beyond
specified limits)
– Ensure that the detailed design and the resulting contract for the works include upgrading
and/or expanding the capacity of the Thung Ham sanitary landfill, if required.
– Ensure that the contract requires the contractor, before he commences work, to provide a
construction plan that sets out how he will maintain the flow in the waterways feeding into
the lakes and protect the works from flooding during construction. During construction, the
contractor will be required to ensure that demolition of houses along the central road to be
constructed in the site is carried out safely in accordance with the contract conditions.
5.2.3 Site-specific Measures for Construction of Chau Giang Wastewater Treatment Plant
Potential impacts of the subcomponent are considered moderate, temporary, and localized and
most of them for the construction of WWTP can be mitigated through the typical mitigation
measures identified in ECOPs. Key site-specific issue is related to the capacity of the sanitary
landfill (Thung Ham) that is required for safe disposal of existing contaminated material which
could increase the risk of airborne and water discharge into surrounding areas. To mitigate this
risk following measures will be carried out by PMU:
– During detailed design, carry out a comprehensive site testing program from which the
landfill design and site management plan for construction would be developed.
5.2.4 Site-specific Measures for Construction of Road D4-N7 and Chau Giang River Bridge
Potential impacts of the subcomponent are considered moderate, temporary, and localized and
most of them can be mitigated through the typical mitigation measures identified in ECOPs.
Key site-specific impacts include (a) land clearance, including trees and other vegetation,
undertaken indiscriminately, without reference to construction site boundaries; (b) the extensive
borrowed material required to construct the road embankments – about 350,000m3 – is sourced
from uncontrolled borrow areas; (c) natural waterways are blocked; (d) construction traffic
causes danger within the construction site and also to residential and other areas outside the site;
(e) vibration from construction equipment damages buildings in close proximity to the
construction site; and (f) batch plants, for concrete and asphalt (if erected on site), emit excessive
polluted gases and water.
To mitigate this risk following measures will be carried out by PMU:
– Ensure that contractor prepares and implements a site specific environmental management
plan (as required by the contract) for each aspect of the works – site clearance, earthworks,
VIWASE – LAVIC Consulting Association
74
temporary and permanent drainage, pavement works, and traffic and site safety. Specifically,
and addition to the general requirements set out in the ECOPs:
– Ensure that there is no land clearance outside defined construction site boundaries
– Ensure that, from the commencement of construction, site drainage is a priority activity, to
include channels, silt traps, flow abatement structures, etc.
– Ensure that borrow areas are developed, operated, closed, and restored in the same manner as
earthworks sites for the project works, and that they are subject to the same EMP and other
contractual requirements
– Ensure that embankments are constructed in a systematic manner, without double handling of
materials, and with constructed surfaces stabilized as soon as they are completed
– Ensure that the earthworks protection measures defined in the contract, to include natural
methods – grassing, shrub and tree planting for example – and artificial methods – stone and
concrete surfacing, fiber or geotextile reinforcement, for example – are adapted to site
conditions as work proceeds and is completed, and are fully implemented
– Ensure that temporary culverts are installed in any natural waterways that are to be crossed
by construction traffic
– Ensure that equipment repair facilities, material stockpiles, and production equipment – batch
plants, for example – are set up away from streams, residential areas, and other sensitive sites
– Ensure that all drivers, equipment operators, etc, are qualified for their respective tasks and
are trained in, and required to adhere to, the site’s traffic management plan.
– Ensure that production equipment, batch plants for concrete and asphalt, are equipped with
dust collection systems correctly operated and maintained, and are connected by pipes or
channels to silt and contaminant traps for wastewater
5.3 MEASURES TO MITIGATE IMPACTS DURING OPERATION PHASE
5.3.1 Measures for Operation of Regulating Lakes in Lam Ha and Quang Trung
During operation, the overall impacts will be positive however, there are some risks that may
cause negative impacts on the local environment and/or local residents. Key risks include
potential generation of excessive odor and local flooding due to ineffective operation and
maintenance of the facilities. To address these risks, the following measures will be carried out
the city.
– Ensure that household and other wastewater does not enter the lakes, to the degree this
can be reasonably prevented;
– Ensure that the lakes are kept free of silt deposits and other blockages, to minimize
flooding risk; and
– Ensure that maintenance of the lakes is included in the city’s operations and maintenance
plan, and that adequate budget is allocated.
VIWASE – LAVIC Consulting Association
75
5.3.2 Measures for Operation of WWTP, Pumping Stations, and Wastewater Collection
Network for Bac Chau Giang
After completion of the project and the Chau Giang WWTP, the pumping stations, box culverts,
and the drainage/wastewater collection facilities are in operation, the wastewater generation from
the service area will be treated and the overall sanitation and water quality in the area will be
improved. However, there are risks on the following: (a) Treated wastewater discharge below
specified quality standards; (b) Plant operated inappropriately; (c) Sludge from treatment process
allowed to remain on site, or discharged other than in a prepared sanitary landfill; (d) Plant
failure results in contamination downstream, causing health and other impacts on the population
living along the waterway into which the plant discharges; and (e) Plant emits odors.
To mitigate these impacts, the following measures will be carried out during the implementation
of this subcomponent:
– Ensure that the contract for construction of the plant includes provision of operations
manual and training operators in the plant’s operations and maintenance
– Ensure that the plant is operated strictly in accordance with the operations manual, and
that staff are periodically trained in its use
– Ensure that the operations manual includes a regime of testing of (i) discharge from the
plant; (ii) sludge produced by the plant; and (iii) ambient air and water quality in the
immediate vicinity of the plant
– Ensure that detailed designs for the plant include tree planting and other means to isolate
the plant from the surrounding residential area
– Ensure that the operations manual contains a procedure for emergency discharge in the
event of plant breakdown, and that the procedure is communicated to downstream
residents and city agencies tasked with managing emergencies of such nature
– Ensure that the operations manual includes a procedure for safely handling sludge from
the plant, including its transport and discharge in the sanitary landfill of the Thung Ham
landfill, and that the latter is maintained and expanded to accommodate the sludge from
the plant in the long term
5.3.3 Measures for Operation of D4-N7 Road and Chau Giang Bridge
After construction is completed, there will be operations of various vehicles on the D4-N7 Road
and Chau Giang Bridge and key short term impacts would include an increased in traffic and
pedestrian accidents, due to higher standard road allowing more and faster traffic; premature
failure of pavements, embankment or cut slopes, and drainage structures due to inadequate
maintenance.
To mitigate these impacts the following measures will be carried out by the city road
maintenance agency:
– Ensure that traffic safety provisions, including signs, lights, and pavement markings, that
were installed during construction are permanently and effectively maintained, and
renewed as necessary;
– Ensure the city’s operations and maintenance plan, and related budget, includes the work
and resources required to maintain the road in its as-completed condition; and
VIWASE – LAVIC Consulting Association
76
– Ensure, with the assistance of the traffic control authority, that overloaded vehicles do not
use the road

CHAPTER 6. ENVIRONMENTAL MANAGEMENT PLAN (EMP)
Based on the assessment of the potential negative impacts discussed in Chapter 4 and the
mitigation measures proposed in Chapter 5, this chapter presents the Environmental Management
Plan (EMP) for the project’s Phu Ly subproject. The EMP identifies actions to be carried out
under the subproject including the environmental monitoring program and the implementation
arrangements, taken into account the need to comply with the Government’s EIA regulations and
the World Bank (WB)’s safeguard policies.
6.1 BASIC PRINCIPLES
– As a part of the EIA, an Environmental Management Plan (EMP) is a safeguards
instrument that is typically used in many projects and which consists of information on
and guidance for the process of mitigating and managing adverse environmental impacts
throughout project implementation. Typically in Vietnam, an EMP comprises a list of
typical mitigation measures to be carried out by contractors, an environmental monitoring
program, organization arrangements, and an estimated monitoring cost.
– There is a comprehensive regulatory framework in Vietnam related to EIA preparation,
environmental standards, protection and management of forest and cultural property, and
other aspects related to construction and operation of facilities and infrastructures in
Vietnam. This EMP is consistent with these regulations.
– To facilitate effective implementation of the EMP, the Phu Ly subproject PMU will: (a)
Establish an Environment and Social Unit (ESU) responsible for ensuring timely
implementation of the EMP, including monitoring, reporting, and capacity building
related to safeguards; (b) Assign the Construction Supervision Consultant (CSC) to also
be responsible for supervision of the contractor’s safeguard performance as part of the
construction contract and this requirement will be included in the CSC terms of reference
(TOR); and (c) Hire qualified national consultants as the Independent Environmental
Management Consultant (IEMC) to assist ESU in performing its task
– The Phu Ly City Water Supply Company, URENCO, and the Department of Transport
will be responsible for implementation of the mitigation measures during the operation
stage of the project and they will ensure that the mitigation measures are implemented
and adequate budget is provided. The Provincial Steering Committee (PSC) chaired by
the Chairman or Vice Chairman of the Provincial People’s Committee (PCP) will provide
the overall policy guidance and oversight of the project implementation. Roles and
responsibility of the specialized agencies and the Departments of Planning and
Investment and Natural Resources and Environment (DONRE) will also be critical.
– In terms of laying out the mitigation measures of the EMP, there are two fundamental
parts to this EMP. Firstly, the City has developed and will use Urban Construction
Environmental Codes of Practice (ECOPs). These ECOPs outline typical generic low-
level impacts that can be expected to occur in a wide range of construction activities of
VIWASE – LAVIC Consulting Association

the project. They include mitigation measures for these impacts and a process for
including them in the construction contracts of contractors. They will be built into all
construction contracts of the project.
– Secondly, all site-specific impacts that are either not covered in the general ECOPs or
which are of an order of magnitude that require mitigation measures not covered in the
ECOPs, are described in more detail in the EMP. The mitigation measures are derived
from the more detailed analysis of Chapter 5.
– Activities to be carried out to mitigate impacts due to land acquisition and resettlement
are presented separately (RP, RPF) and they will be carried out and monitored separately.
– Some components of the project will finance environmental measures, above and beyond
mitigation measures as described in the EMP. This is the case for Component 4.1 which
will finance the PMU’s EMP oversight program, including safeguard training; and
Component 4.2 which will finance environmental and resettlement monitoring.
6.2 KEY MITIGATION MEASURES

5. Drainage and sedimentation control
The Contractor shall follow the detailed drainage design included in the construction plans, intended to prevent storm water from causing local flooding or scouring slopes and areas of unprotected soil resulting in heavy sediment loads affecting local watercourses.
Ensure drainage system is always maintained cleared of mud and other obstructions.
Areas of the site not disturbed by construction activities shall be maintained in their existing conditions.
Earthworks, cuts, and fill slopes shall be properly maintained, in accordance with the construction specifications, including measures such as installation of drains, use of plant cover.
To avoid sediment-laded runoff that could adversely affect watercourses, install sediment control structures where needed to slow or redirect runoff and trap sediment until vegetation is established. Sediment control structures could include windrows of logging slash, rock berms, sediment catchment basins, straw bales, storm drain inlet protection systems, or brush fences.
Site de-watering and water diversions: In the case that construction activities require that work be carried out within the watercourse (e.g. culvert or bridge crossing construction, retaining wall construction, erosion protection works), the work area must be dewatered to provide for construction in dry conditions. The sediment laden water pumped from the work area must be discharged to an appropriate sediment control measure for treatment before re-release to the stream.
Use techniques such as berming or diversion during construction to limit the exposure of disturbed sediments to moving water
Stream diversions or construction of cofferdams would require site-specific mitigation measures in the EMP.
