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
development and inter-regional exchange, and attract investments to the province
- Support capacity building for the PMU implementing the project to ensure the project
is prepared and implemented effectively to meet the goals of the project, in
accordance with the requirements of the Vietnam Government as well as The World
Bank. Capacity building and technical assistance to agencies involve with urban
planning and urban asset management.
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.

temperatures of summer and winter are in contrast with those of spring and autumn are
transitional periods. Summer lasts from May to September; winter is from November to mid
March; spring begins in mid March till in April and autumn from October to mid November.
2.1.2.1. Temperature
The project area is located in the climate region of the Bac Bo Delta with the
characteristics of tropical monsoon climate- contrasting temperature changes between the
seasons. The average annual temperature is about 23-240C, average hours of daylight is
1100-1300 hours/year. In a year, there are from 8 to 9 months where the average
temperatures are over 200C (5 months of which are above 250C); temperatures fall below
200C for only 3 months and so far never below 160C (Figure 2-1).

2.1.2.3. Wind regime
There are two main seasons: summer and winter. In the summer, the main directions are
south, southwest and southeast while in the winter, main directions are North, East and Northeast.
2.1.2.4. Unusual weather patterns
Storms affect the region from about May to November each year, causing heavy rain
and strong winds with speeds of up to 100 km/h, and the normal rainfall average is estimated
to be up to 1,000 mm.
2.1.3. Geomorphic and topographic condition
Phu Ly city is located in the plain along rivers; the terrain is divided by the rivers and
low areas. The general slope of the city’s terrain is from West to East. The topographic
features of the city are as follows:
- The topography of the old city area in the east of Day River and new urban areas in
the west of Day River is raised, reaching the elevation of 3.0 m - 6.8 m;
- The topography of Phu Van region in the north of Day River and Chau River is also
raised, reaching the elevation of 3.0 m - 4.5 m.
- The area of rice fields and vegetable fields has an elevation of 1.8 m - 2.2 m.
- Low areas of ponds/marsh have an elevation from - 0.8 to + 0.4 m, are the low areas
north of Chau River and east of Day River where the interconnected ponds, lakes and low
fields are frequently flooded.
Phu Ly city is located at the intersection of the Day, Nhue and Chau Giang rivers and
is enclosed by a dyke system (Figure 1-2). The water outlets to the rivers are influenced by
the hydrology of the Day River. The ground water level in the area depends on the water
level of the river which is subject to seasonal changes.
Phu Ly city lies within the earthquake zone of warning level 8 (according to the
forecasting document of the Global Physics Institute).

2.1.4. Hydrologic conditions
The annual volume of average rainfall in Ha Nam province is about 1.602 billion m3.
Annual surface water run-off from the Red, Day and Nhue rivers into the territory is about
14.050 billion m3. Groundwater flows through the territory is always supplemented by those
from other regions. Ground water in Ha Nam exists in many layers and is of good quality,
sufficient to meet the demand for socio-economic development.
Figure 2-5: Intersection of Day, Nhue and Chau rivers in the Ha Nam province
- The Day River is a tributary of the Red River, derived from Phu Tho, flowing into
Ha Nam territory. The Day River is the boundary between Ha Nam province and Ninh Binh
province. The river has a length of 47.6 km in Ha Nam province
- The Nhue River is a tributary of the Red River from Thuy Phuong (Tu Liem, Hanoi)
into Ha Nam province with a length of 14.5 km, and it then flows into the Day river (Phu Ly
city).
- The Chau Giang River originates in Phu Ly city and splits into two branches at Tien
Phong (Duy Tien) River. One branch is the boundary between Binh Luc and Ly Nhan district
VIWASE-OCI Consulting Association 26
and the other branch is the boundary between Binh Luc and Duy Tien district. Sat River is a
branch of the Chau Giang River in the Binh Luc district.
According to the study on hydrology in Phu Ly city, the Chau Giang is a large branch
of the Nhue River. It receives run-off from the city and then flows to the Red River. The
Chau Giang River is affected by water from the Nhue river and is always polluted seriously
due to a lack of circulation, leading to the adverse impacts on community’s health especially
those in Ly Nhan and Binh Luc district. The monitoring data for river water quality recently
showed heavy contamination of water sources. Aquatic life in the rivers is very limited.
2.2. SOCIO – ECONOMIC CONDITION
2.2.1. Population and Population density
According to statistics combined with the results of the census dated 1/4/2009, there
are 19,110 households in the city, with a population of 86,920 people. The population at the
administrative units is as follows (data surveyed in 2009) (see table 2-1).

50.3%. Rural population accounts for 51.1%; the inner city (6 wards) accounts for 48.9% of
the population of the city. The population growth rate in the period 2005-2009 has not
changed much, on average, about 0.8 - 0.9%/ year.
2.2.2. Occupation and Income
Over the past few years, Phu Ly has achieved high economic growth rate, of which
industry increases by 15-16% per year, agriculture and services increases by approx. 4% and
20% per year respectively. The economic structure is in positive form; the industry-
construction share of GDP has gradually increased and reached 37.4% in 2005; services
increased by 50.3% while agriculture decreased to 12.3%. The average GDP per capita of the
City in 2009 increased to 5 million Vietnamese dong. The average food consumption per

VIWASE-OCI Consulting Association 27
a. Industries and handicrafts
Currently, Phy Ly has more than 7,800 industrial and handicraft manufacturers, including
57 state-owned enterprises, which attract nearly 12,000 employees. Most local enterprises
undergo stable development and standing in the context of the market economy. Private
manufacturers develop strongly in terms of both quality and quantity. Two industrial
complexes are under construction in Thanh Chau and Chau Son.
b. Agriculture
In recent years, farmers have become active in changes to livestock and cropping patterns.
Advanced farming techniques have been adopted resulting in high and consistent crop yields.
The crop structures have been formulated stably, of which winter crops have become the key
crops. During the 2005-2009 periods, the agriculture output increased 2.3% per year in
average.
c. Commerce – Service - Tourism
In recent years, the economic structure of the city has shifted positively with the
increased proportion of industry-construction and reduced proportion of services, agro -
forestry - fishery.

private clinics. There are now 5 provincial hospitals, a city hospital and 12 commune clinics.
Currently, six of twelve wards/communes have reached national health standards.
2.2.4. Education
Investments in kindergartens and basic education have been focused to improve
facilities and teaching quality. Currently, the city has 38 schools including 12 nursery schools
and kindergartens; 11 primary schools; 10 secondary schools and 5 high schools.
2.2.5. Culture, history and tourism
The cultural, historical and tourism sites in Phu Ly city are listed in the table below.
In Quang Trung ward, there are two provincially classified structures: Song Nham Chi At
ancestral temple of the Vu families and the Mau temple.
However, in the area of construction of the Phu Ly subproject, there are no historical,
cultural, or religious properties. There is only a pagoda called Lac Trang pagoda in Quang

2.3. INFRASTRUCTURE
2.3.1. Drainage and wastewater treatment systems
Overview
Rainwater drainage and flood control systems
Rainwater drainage depends on agriculture irrigation. Planning area is under the basin
drainage of Chau Giang River. Rainwater is collected in the channel network leading
to Lac Trang lake through Lac Trang pumping station (capacity of 29,000m3/h) and a
part of it during Phuoc pumping station (with capacity of 80,000m3/h) to Chau Giang
river.
Flood control system: the dyke of the Chau Giang River is from 5.2 to 5.55 m
height; Nhue River’s dike is the road-bed of National Highway 1A, with the height
ranging from 5.4 to 7.0m. When the level of river water increased, the stop-log gate is
closed and the rainwater in the entire basin then pumped into the river.
Sewage system and environmental sanitation
VIWASE-OCI Consulting Association 29
The city has a combined drainage system in the old urban areas and separated drainage
system in the new urban area (Bac Chau Giang area). The combined drainage system in the
old urban areas is relatively stable, while in the new urban areas, the drainage system is still
under constructione. Drainage collection systems and treatment plants are being built in each
area.
Currently, domestic, industrial and hospital wastewater as well as agriculture wastewater
is discharged directly into the storm water drainage and then into existing water bodies of the
city including Chau Giang, Nhue and Day Rivers.
Some assessments concerning the drainage system of the city:
- The current drainage system is divided by terrain, into three main basins: the old urban
areas in the East, including the southern area of Chau Giang River, East Day River; western
area of Day River, and North Chau Giang;
+ The western area of Phy Ly city (Bac Chau Giang new urban area) has increasingly
developed in infrastructure upgrading, according to the Phu Ly Master Plan, rain water and
wastewater will be collected separately but the drainage system and wastewater treatment
plant have not been built yet.
+ The center of the East area (the old urban area - South of the Chau Giang river) uses
combined drainage system for both storm water and wastewater. In the newly constructed
urban areas of the South (South Tran Hung Dao area, Liem Chinh, Thanh Chau...), the
drainage system has been built separately for storm water and wastewater, while collection
and treatment systems are under construction.
+ In the north Chau Giang, infrastructure of residential areas is very limited.. In the
newly constructed areas, infrastructure system is not invested synchronously, storm water and
wastewater drains are built separately, and the collection and treatment systems have not been
built as of now.
- Generally, the drainage system is limited and low in density; the drainage system is not
systematic and synchronous.
- Some drain systems are small in cross section, only capable of surface drainage and
incapable of a regional drainage function.
- Due to new urban development, the natural terrain is partitioned; lakes, canals and
fields have been narrowed, causing decreases in natural drainage area.
- Poor drainage system design will result in slow withdrawal of rainwater, thus causing
partial flooding.
- The management, construction, and maintenance of the drainage systems are
inadequate, causing damage or congestion to the drain system.
- In recent years, the urban drainage system of Phu Ly has been invested and constructed
significantly. However, not all transportation routes have drainage facilities. Drainage system
needs to be extended equally on roads and major pumping stations and reservoirs to ensure
drainage for expanded urban areas as well.
VIWASE-OCI Consulting Association 30
- Urban flood is extensive, due to stagnant water in streets having no drains and lacking
pump stations and the rising water level of the rivers during flood events
+ Flood caused by the lack of drains leading to pumping stations; moreover, pumping
stations are too small compared with the large area of the water collection basins.
+ Flood due to overflow of rising water level of the rivers (flood discharge of Day river).
This case rarely happens.
Status of drainage and wastewater treatment in the project area
The areas within the scope of the project have insufficient capacity for drainage and
wastewater treatment. According to surveys of the study team, there is no drainage system for
stormwater and wastewater in Quang Trung Ward. The area has topographic elevation lower
than roads and dykes around. Specifically: project area’s average ground altitude is from +2.2
m to +3.5 m except the area near the embankment road of Nhue River of which the altitude is
from +4.5 m to +5.4 m. This area is surrounded by the Nhue River dyke system (altitude +4.5
m to +5.4 m), Chau Giang River dyke (altitude +4.5 m to +5.5 m) and National Road 1A
(altitude +5.9 m to +7.0 m).
Among the 696 households in the project area of Quang Trung Ward, there are 437
households using septic tank toilets (three-compartment toilets) (62.78%), 29 households
using simple septic-tank (4.17%) and 230 households using flushing toilets (33.05%).
Hoa Lac Village of Lam Ha Commune does not have sewer system yet. The drainage
is mostly done by self-penetration to the soil and discharging into Chau Giang River. Hoa
Lac Village is characterized by high terrain in the middle area (altitude +4.2 m to +5.7 m),
lower on both sides (North half’s altitude +2.5 m to +3.7 m, South half’s altitude +2.9 m to
+3.5 m). Chau Giang River dyke, which is located in the North (Street TL493), has an
altitude of +5.0 m to +5.5 m.
The terrain of Me Noi Village, Liem Chinh Ward has an average altitude of +2.5 m to
+3.5 m, sloping from North to South. Chau Giang River dyke has an altitude of +6.5 m to
+7.0 m. Similar to Hoa Lac Village, the area of Quang Trung Ward, Me Noi Village does not
have sewer system yet. Currently the drainage is mostly done by self-penetration to the soil
and discharging into irrigation ditches in the South (near the Road 42 m, which is currently
under construction).
2.3.2. Water supply system
Overview of the water supply system in Phu Ly city:
The existing status of water resources systems and water treatment plants:
The water resources used for water supply in Phu Ly City is surface water from the Day river.
This supplies 2 water treatment plants.
- Water supply treatment plant No. 1 located in Quang Trung ward, with capacity of
10,000 m3/day, built in 1997
- Water supply treatment Plant No. 2 located in Thanh Son commune, Kim Bang district
with capacity of 15,000 m3/day, built in 2001
VIWASE-OCI Consulting Association 31
Traditional treatment technologies: Raw water - Mixing - Reaction - deposition - Filter –
Disinfect
Water supply output in 2009 was 4.5 million m3 (16,600 m3/day including water loss of
about 35%).
The status of water supply network:
The water supply network includes a pipeline that connects consumer households
comprises of conveyance, distribution and services lines and various materials such as
cast iron, plastic and galvanizediron pipes. About 96% of the city’s population is
connected to the supply network. Total length of the main pipelines is around 25km with
diameter 100 – 300 mm
General assessment
- Treatment plant has not yet operated at its full design capacity (about 70%)
- Scope of service is primarily for the city center. The city’s water supply company is
not responsible for the water supply system in the districts of the province.
- The applied water tariff includes environmental charges and it has currently been
increased to cover sufficiently production costs
- The company has been privatized therefore its management model has changed.
- The loss ratios is 35%, the number of water meters is 13,300 of which 320 meters
belong to state agencies.
- Quality of raw water can be affected due to the pollution of water in the Day and
Nhue rivers
Quality of raw water can be affected due to the pollution of water in Day river and Nhue
rivers Water supply status of project area
The project area at Quang Trung ward consists of populated areas of groups 6-10 with
696 households and 2,868 people. The demand for clean water is at Quang Trung ward is
very urgent. Clean water is only provided for 45 households living in-group 7 accounting for
6.5% of households in the project area. These include 35 households located near National
Highway 1A and about 10 households located inside Highway1A about 60 – 100 m. Water
supply service network for these households consists of D32 and D25 tubes with the length
of about 110 m and 250 m, respectively. These tubes were constructed in 2006 associated
with the construction of the Highway 1A expansion through these households of this group.
The majority of households in project areas use rainwater and well water as drinking
water source. Over 80% of households have rainwater tanks, 45% of households have drilled
wells. When Nhue river water is contaminated, the quality of water from nearby drilled wells
is not guaranteed for people’s health.
Because water is not hygienic, the percentage of people suffering from diseases related
to water resources in the project area is higher than the surrounding wards using clean water
from the water supply company. According to the statistics of Quang Trung ward health
station, from 2000 to present, in the project area the average number of people suffering from
skin diseases is double that of the city.
VIWASE-OCI Consulting Association 32
Water supply system is currently not available in Hoa Lac village area. The majority of
households use rainwater and well water as drinking water source. More than 75% of
households have rainwater tanks, 60% of households have drilled wells.
Me Noi village has previously been supplied clean water from a water supply station
with 100 m3 day capacity, from water supply Liem Chinh cooperation. Currently, this water
supply station is damaged and no longer in operation. Thus, majority of the households there
do not have access to clean water. In the village, there are only about 15 households along the
dike road of Chau Giang river near junction with Tran Hung Dao road have access to clean
water from the water supply company. Recently, due to the imperative demand for clean
water, these families, from their own funds, constructed and installed a steel and galvanized
pipeline which connects D32 and D25 service pipes with the length of 60 m and 95 m,
respectively, to transfer water from clean water pipes in intersections for their domestic and
business needs. The rest households use rainwater and water well for their domestic purpose.
About 80% of households have rainwater tanks, 65% of households have drilled wells.
2.3.3. Status of solid waste management and treatment
- Domestic waste:
The total solid waste of the city is around 15,534 tons per year (43.14 tons/day), which is
collected and treated by the city’s Urban Works Company to produce organic fertilizer at a
processing plant at Thung Dam Gai, Thanh Thuy commune, Thanh Liem district of the city.
- Hazardous waste:
To dispose of generated hazardous waste, companies in the city and in the industrial
zone (small and handicraft industries) have to sign an environmental protection commitment
with the Ha Nam Resource and Environment Department (DONRE) and report their waste
sources, types, quantity, and composition of each hazardous waste. This information is
recorded in DONRE’s waste source book.
The City People’s Committee requires each private general clinic to have a contract
with hospitals regarding health waste treatment before they are granted the environment
commitment certificate under the environment protection scheme.
Since October 2009, the solid waste processing plant, producing organic fertilizer
using Belgian technology has been under operation. This plant is located in Thung Dam Gai
landfill (Thung Ham), Thanh Thuy commune; Thanh Liem district has burial sites with the
area of 14 ha. Capacity of solid waste treatment is about 55 tons per day (the residual
capacity of 65 tons per day). Microbiological fertilizer products are sold by the company in
the city.
2.3.4. Existing transportation status
+ Railway:
North-South railway: runs parallel to National Highway 1A, and is a meter
guage single track facility;
Specialized railway runs from the Phu Ly station to the Thinh Chau station
and the But Son cement factory, 5 km long, with single 1 meter guage track.
+ Waterway:
VIWASE-OCI Consulting Association 33
The Day River route: 8 km in length, third level engineering standard of river,

The Chau Giang River route: 4.5 km length, average width is 130 m; min
depth is 3.5 m;
The Nhue River route: 3.5 km length, average width of 60 m; min depth is
3.0 m;
+ Roads:
National Highway No.1A (Le Hoan Street) runs through Phu Ly city with 3.7
km length; the road’s surface is made of asphalt concrete, sections:
5m+11.5m+2m+11.5m+5m+5m
Highway No.21B: Running through Phu Ly city is 0.5 km long. The road’s
surface is made of asphalt concrete, 5 m in width.
Highway No.21A (Dinh Tien Hoang, Tran Binh Trong, Dinh Cong Trang, and
Ly Thuong Kiet Streets): Running through Phu Ly city is 9.5km. The road’s
surface is made of asphalt concrete, 12 m in width.
Provincial Road No.971 (Tran Hung Dao street to Ly Nhan): Running through
Phu Ly city is 2.5 km; 7 m in width;
Cau Gie – Ninh Binh Highway to the east of the project area: under
construction;
Inner-city traffic: The city’s inner city network is based on a grid, with roads
about about 150 – 200 m apart; all roads have been asphalted. The road
network in the east of the city is degraded with no pavements. The road
network in west is new, and the quality is still good.
Total length of the Phu Ly city’s road network: 236.5km
In which:
+ Inter-provincial roads: 29 km
+ Urban roads: 33.5 km
+ Roads in villages, hamlet, roads to field.: 174 km
Traffic situation at the point of project implementation
The internal roads system at project area of Quang Trung ward is underdeveloped and
not appropriate for the functions of the city’s inner ward. Beside Nhue river’s dyke routes
made of concrete has cross-section of about 2.7 m to 3.5 m, internal roads in the area are
mostly earth roads (about 40%), gravel roads (about 30 %) and concrete road (about 30%).
Most of the roads have been degraded seriously; some of them are often in muddy condition,
especially in rainy time. Crossroads are only from 2 m to 3 m, each section has a width of
about 1.5 m. The present road situation generates obstacles for economic development and
people’s walking and construction activity, especially in these days of heavy rain causing
flooding.
VIWASE-OCI Consulting Association 34
The traffic system in the Quang Trung ward is composed of mainly alleys with small
cross section, so its connection with outside residential areas face many difficulties. The
region seems to be isolated, and does not fall in line with strong economic development of
neighborhoods area.
The system of internal roads of Hoa Lac village is underdeveloped; including
concrete roads (about 45%), soil road (approximately 25%) and gravel road (about 30%).
Crossroads are from 2 m to 3 m. Some roads are deteriorated and need to be renovated.
The system of Me Noi village internal roads has not yet been developed including
concrete roads (40%), soil road (20%) and gravel (40%). Crossroads ranges from 2 m to 3 m.
Some roads are deteriorated and need to be renovated.
Due to the fact that internal roads are residential alleys, main transportation vehicles
are rudimentary load small vehicles, requirement for load bearing capacity of the route is not
high. To match actual demand and investment cost savings, it is proposed that design
standards for road load are not applied
2.4. ENVIRONMENTAL QUALITY
To assess environmental quality baseline in the project area, samples were taken on
21st June 2010 and on 31st July, 2010 for analysis. Locations of environmental samples, the

Note: QCVN 05:2009/BTNMT - National Technical Regulation on ambient air quality
Remark:
The survey conducted in June and July 2010 showed that the air quality at the project
sites is fairly good; monitored parameters were within permissible limits set by Vietnam
technical regulation on ambient air quality (QCVN 05:2009/BTNMT). The dust content in
the air at the survey sites range from 0.098 to 0.23 mg/m3. At sites where there is high
density traffic serving the construction sites of urban infrastructure (the road between Lam
Ha 1 Lake and Lam Ha 2 Lake) and where other construction activities are taking place (Phu
Ly drain), dust concentration reaches 0.22 – 0.23 mg/m3. In general, except sample M8
which shows high level of CO (330 ppm), the level of harmful gases i.e. SO2, NOx, CO in all
analyzed samples is low, within permissible limits set by Vietnamese regulations. The
average sound pressure level for 1 hour at the proposed project sites ranges from 53 - 66 dBA
meeting the norm of TCVN 5949-1998.
As a result, the air quality of the proposed area where the project will be implemented
is quite good ; just some zones where there is transport activities, dust content is higher than
the average standard (but below the allowable standard limit); other toxic gases and sound
pressure are nominal and in line with Vietnam Standards.

Results from the analysis indicate that water at the project sites is polluted by organic
compounds. In general, BOD and COD parameters of the surface water samples (river, lake) are
much higher than the allowable standards of QCVN 08:2008/BTNMT, B1 category. BOD5
ranges from 12.6 to 47.0 mg O2/l, highest at the lake of the Me Noi hamlet (SW3 sample, Table
2-7). Water in the Chau Giang River at the Liem Chinh village has BOD at 24.9 mg O2/l which
is 1.7 times higher than the standard. Surface water of Quang Trung Lake, Lam Ha 1 Lake and
Lam Ha 2 Lake has BOD ranging from 22.1 – 32.8 mg O2/L which is 1.5 – 2.19 times higher
than allowable standard.
The COD concentration ranges from 30.0 to 81.5 mg O2/L and is highest at the Me Noi
hamlet. The Chau Giang River water at the Liem Chinh commune has the COD concentration of
42.1 mg O2/L, 1.4 times higher than allowable standard. COD concentrations of surface water at
Quang Trung, Lam Ha 1 and Lam Ha 2 Lakes are 34.1; 42 and 73.0 mg O2/L which is
respectively 1.1; 1.4 and 2.3 times higher than the allowable standard.
DO concentrations of most samples range from 1.13 – 2.52 mg O2/l which do not reach
allowable standard ( 0.4 mg O2/l).
Nutrition substances such as N, P of several analyzed samples exceeded Viet Nam
technical regulation QCVN 08:2008 B1 category regarding NO3-, NH4
+ and phosphate
(agricultural water sample at Me Noi hamlet, Quang Trung Lake, Lam Ha 1 Lake and Lam Ha 2
Lake). This shows the potential of creating eutrophication to the hydrological zone.
These results reflect the findings in the National Environment Situation 2006 report on
the subject of the environment situation of the rivers: Cau, Nhue, Day and Dong Nai.
Accordingly, the Nhue and Day basins are polluted mainly by organic substances and other
nutrition substances with the major source being domestic wastewater from Hanoi. From the
results, it can be stated that the water quality of Nhue River since 2006 has not improved. For
detailed data please refer to the appendix of this report).
The results indicate that water in samples taken from channel A46 (sample SW11) is
heavily polluted, particularly the concentration of BOD and COD. They are about 2 times higher
than the permitted standards. Content levels of ammonium, iron salt and phosphate exceed by
more than 10 times the permitted standards of QCVN 08:2008, category B1.
2.4.2.2. Groundwater quality
In order to assess the quality of groundwater, samples were taken at Me Noi hamlet,
Liem Chinh village (6 m deep dig well), Trieu Xa hamlet, Liem Tuyen ( 25 m deep drill well);
group 9, Quang Trung ward (25 m deep drill well); Duong Am hamlet, Lam Ha village (28 m
deep drill well). Surface water sampling locations and analytical results are shown in Table 2-8
and Table 2-9.
The analysis result shows that pH and TDS of all samples meet QCVN 09:2008/BTNMT
(National technical regulation on underground water quality). Concentration of NO3- at the dug
well water sample at the Me Noi hamlet, Liem Chinh village exceeded underground water
standard set by QCVN 09:2008/BTNMT. The dug well water sampling location is next to the
VIWASE-OCI Consulting Association
40
agriculture area of the hamlet, and this is a possible reason for the pollution as water from that
area has been polluted as well. It is notable that most of the groundwater in the area is polluted
by coliform, a potential cause of intestinal disease. This health risk is very high since it is
common practice for households to extract groundwater for domestic use and case data are
available to prove this. Therefore, the sanitation environment in the project area will be
significantly improved as the project has provision for fresh water supply accessible to each
household in Liem Chinh ward, Lam Ha and to most of the households in Quang Trung ward.
The concentrations of NH4+ in all analyzed water samples are extremely high with the
lowest NH4+ concentration exceeded the allowable standard by 8 times which emphasizes the
urgency for improving the water supply system in the project for the proposing project sites.

2.4.3. Soil/ mud quality
Soil sampling locations are shown in Figure 2-6 and Table 2-10. Analytical results on soil
quality are shown in Table 2-11.
The analysis results show that the concentrations of heavy metals i.e. Zn, Pb, Cd and As
in all soil samples are lower than the allowable limits of QCVN 03:2008/BTNMT (National
technical regulation on the allowable limits of heavy metals in the soils, type 1.3.1: soil for
agricultural land). However, the concentration of Cu at the field of Lam Ha commune (sample
Đ2) is 54.95 mg/kg dry sample, slightly higher than the standard of 50 mg/kg dry sample.

Currently, in Vietnam, we have no technical regulations for sediment or sludge. Thus, to
assess the quality of sludge, we apply QCVN03:2008/BTNMT type 1.3.1 (for agricultural soil)
and/or type 1.3.3 (residential soil). The analytical results show that the concentrations of metals
such as Cu, Zn and Pb in some samples (in Quang Trung ward, Lam Ha 2) exceed the allowable
standards. The pollution of Quang Trung ward can be explained by the fact that Quang Trung
lake has received sewage water from residential areas of Quang Trung ward.

CHAPTER 3. ANALYSIS OF ALTERNATIVES OF THE PROJECT
The project’s proposed investments are those that are presented in the city’s master plan towards
2020 which has been approved by Ha Nam Provincial People’s Committee. While alternatives
were considered in the preparation of the master plan, they were further considered where
necessary during the project’s feasibility study and related EIA preparation.
3.1. WITHOUT PROJECT CASE
In case of without this project, clearly that there would be different environmentally problems
raising:
Firstly, according to the actual situation in the old urban area, the flooding situation occurs
frequently in the Quang Trung, Liem Chinh and Lam Ha ward. The sewage of many families
is not treated through septic tank, self- absorbed in family’s land or flow into Quang Trung
and Lam Ha 1, 2 lakes. Thus, this causes smell pollution, losing urban landscape and creating
sources of infectious diseases greatly affecting the quality of people’s life. In the future, with
increasing population and their daily needs, the amount of wastewater will also rise over time.
Therefore, the pollution level will be increasing and will affect adversely the community.
Secondly, due to the rapid urban development and increasing population, the number of
tourists every year in city is large, and they lead to increased demand for domestic water use
so that wastewater will also rise creating more pressure on the environment in the future.
Thirdly, in the Quang Trung, Liem Chinh, Lam Ha ward, the current infrastructure is very
poor. Most people there are using deep wells and water wells for use in daily activities.
Domestic wastewater is discharged directly to the natural environment around the area in
which people live, causing an unsanitary situation. Difficult transport
systems are also an obstacle for economic development and improvement of quality of life. In
addition, if an elementary school and kindergarten are not constructed, it will put pressure for
pre-schools and primary schools in other surrounding areas (potentially overloaded).
Moreover, people in the ward have to take their children to study in remote places, crossing
railway being easy to meet traffic accidents and other risks.
The main contents of Vietnam Medium Cities Development Project – Phu Ly City subproject
are improvement of technical infrastructures, investment in water supply, construction of
schools, dredging of lakes and traffic development. As mentioned in Chapter 1, the project is of
high sustainability for urban development and environmental sanitation when it is put into
operation. The project will be systematic and synchronous in a relatively large scale; the
effectiveness hereof will meet socio-economic development requirements and provide a
sustainable environment.

3.3. ALTERNATIVES OF PROJECT PROPOSALS
For Phu Ly City, the principle investments for which alternative analyses were carried
out are (i) the proposed WWTP; and (ii) Road D4-N7, the core road of the proposed new urban
area’s road network and iii) infrastructure in Quang Trung Ward. The results of the analyses are
presented below.
3.3.1. Alternatives for Component 1
Rehabilitation and upgrading of Quang Trung Ward infrastructure is an important
investment item; therefore, after revision and reference to opinions related agencies and public
consultation, it is proposed to adjust the alternatives for investment in drainage and wastewater
treatment systems in Quang Trung Ward and the scale of main traffic axis (new construction).

more social and environmental
impacts than alternative 2.
Cross section of 9.5 m
-Reduction of resettlement and
land acquisition. Thus, cost will
be reduced, and generation of
less social and environmental
impacts than option 1-
After consideration, alternative two was selected as it is cost effective and generates less
environmental and social impacts than alternative one. Moreover, Quang Trung ward stands
almost isolated from Phu Ly City, the traffic flow of the expected route will not be high, and thus
the wider road would not be needed.

For location, the selection factors considered included area of land required, environmental and
socials issues, whether gravity or pumped feed would be needed, interaction with ongoing and
planned developments in the area, capital and operating cost, and others. The analysis concluded
that option 1, a location in the northwest corner of the new urban area, would be the most
suitable. The principle reasons for selecting this alternative were low land area requirement,
moderate construction, and operating cost and suitability for stage 2 expansion when this became
necessary. In addition, this option will generate less social and environmental impacts compared
to other alternatives. It should also be noted that the wastewater network to be constructed in the
new urban area cannot be connected to the existing or under-construction wastewater treatment
plants in the south of the city, because these are on the other side of the Chau Giang River, and
also because neither plant has the capacity to accept the large additional flows that will come
from the new urban area.

For technology, four alternatives were considered: advanced oxidation ditch, waste
stabilization tank, traditional activated sludge, and bio-filtration tank. As for the plant’s location,
from the above comparison, it is concluded that the advanced oxidation ditch technology was the
most appropriate for the project. This selection was based on its environmental friendly feature,
low land area requirement, simplicity of operation, and reasonable capital and operating costs.
The appropriateness of the location and technology will be further studied and if
necessary adjusted prior to detailed design under a parallel Urban Sanitation Strategy, financed
through the World-Bank provided Project Preparation Technical Assistance Facility.

3.3.3. Alternatives for Component 3
Road D4-N7
The proposed Road D4-N7 forms the north-south corridor of the planned new urban area.
Its ultimate configuration will be dual carriageway, with each carriageway containing 4 lanes.
The initial configuration, Phase 1, to be constructed under the proposed project, will be two lanes
in each carriageway with a wide central median within which the future additional 4 lanes will be
constructed. Since the terrain through which the road passes is uniformly flat, being largely used
for rice cultivation and as the road forms the core of an extensive future urban road network plan,
no alternative alignments were considered. For the same reasons, the do nothing alternative was
not considered. The alternative analysis covered phasing of the road’s construction, and aspects
of technical design, such as widths, road safety improvements, etc. The selected alternative is the
first phase of the road’s ultimate configuration, with widths, road safety features, etc, that are
adequate for traffic projected to use the road during its initial service period.

CHAPTER 4. ENVIRONMENTAL IMPACT ASSESSTMENT
When the project is completed, the overall impact will be positive. The overall impacts will
be positive. Nevertheless, the project will cause some negative impacts (temporarily or
permanently) on the local environment and local population. The nature and extent of the
impacts are discussed in this chapter.
The assessment was made based on the primary and secondary data which were collected
during the EIA study including review of documents/reports; field visits to the project areas and
the proposed construction sites; collection of water quality, air, and noise data; and discussions
and meetings with the local agencies and local people. To mitigate the impacts, effective
implementation of mitigation measures will be necessary.
This chapter identifies and assesses the potential impacts of the Phu Ly City Subproject based
on the environmental and social data collected during the EIA study, taking into account the
national and international experience on EIA preparation, the Government EIA’s regulations, and
the World Bank’s safeguard polices that have been triggered for the project.
Section 4.1 briefly describes the potential positive impacts of the project as described in the
feasibility study while Section 4.2 identifies potential negative impacts of the project on the
physical, biological, and socio-economic environments using a checklist method. Section 4.3
discusses key impacts of the project by subcomponents during preconstruction, construction, and
operation phases. The proposed mitigation measures are discussed in Chapter 5 while the
Environmental Management Plan (EMP) is provided in Chapter 6.
4.1 POTENTIAL POSITIVE IMPACTS
a. Urban traffic system
The construction and upgrading of roads within the project aims to upgrade the infrastructure and
improvements of some peri-urban areas with poor infrastructure, improve the circulation of the
project areas with surrounding areas, and improve sanitation of the project areas.
The project aims to build new urban roads, linking the southern Chau River to northern Chau
river residential area of Phu Ly town, enhancing the movement capacity to other areas. The
construction of urban roads and bridges across the Chau river will reduce the density of traffic in
provincial road No.493 in northern of Chau river, particularly to reduce traffic accidents at the
junction between the provincial road No 493 to national road 1A and the railway North – South,
and to help local residents access public transport.
b. City rainwater and wastewater drainage system
Enhancements of rainwater drainage capacity create good conditions to collect and treat
domestic wastewater in city. These are improvements in environmental sanitation conditions to
improve human health, contributing to the infrastructure completion and development, and to
meet the demand on the City’s general development.
c. Water supply system, kindergartens, and primary schools
Good domestic water quality will improve environmental sanitation conditions for direct
beneficiaries of the Project (residents of Quang Trung ward (2,868 people) and Liem Chinh ward
VIWASE-OCI Consulting Association
52
(Me Noi village) (1,329 people), Lam Ha Commune (Hoa Lac village)) (1,274 people).
Accordingly, health conditions of the community will be improved.
The school system (primary school capacity for 500 pupils, kindergarten capacity for 350
children) will benefit from the additional investments.
d. Rehabilitation and renovation of reservoirs and construction of water pumping station
Dike rehabilitation, reservoir renovation and construction of pump station provide for reservoirs
dredging improving the environmental quality and create compatible regional landscapes upon
completion of the project. Aside from the direct beneficiaries of households located around the
reservoirs, other households in the area and Phu Ly City will also enjoy a clean urban space with
beautiful scenes, contributing to improvement of regional socio-economic development.
Moreover, such rehabilitation partially enhances the flood drainage capacity and disease
prevention during rainy seasons.
e. Construction of wastewater treatment plant for Bac Chau Giang Urban Area
When the wastewater treatment plant is completed, approximately 3,000 m3/day of urban
wastewater will be treated in accordance with the national standards (Vietnam National
Technical Regulation 24:2009/BTNMT, category B) before discharging to the Chau Giang
River. This will reduce water pollution emissions into the river.
4.2 IDENTIFICATION OF POTENTIAL NEGATIVE IMPACTS
4.2.1 Type and Scale of Project Impacts
Based on the analysis of baseline data, field visits, and discussion with key officials and
stakeholders, the potential negative impacts on the physical, biological, and socio-economic
environment of the project have been identified. Table 4.1 summarizes the potential impacts by the
project subcomponents while the level of impacts is assigned as follows: None (N) –no impact;
Low (L) – Small works, minor impacts, localized, reversible, temporary; Medium (M) –Small
works in urban/sensitive areas, medium scale works with moderate impacts of which most are
reversible, reducible and manageable, localized, temporary; High (H) –Medium scale works in
small urban /sensitive area, large scale works with significant impacts (socially and/or
environmentally) of which many are irreversible and require compensation. The residual impacts
of the projects, after implementation of mitigation measures, are mostly negligible as will be
discussed in Chapter 5.
In general, all the project activities to be carried out under Component 1 (Basic Infrastructure
Upgrading and Service Improvement), Component 2 (Water Supply and Environmental
Sanitation), and Component 3 (Urban Roads and Bridges) will involve small and/or medium scale
civil works of which most of the potential negative impacts are reversible, temporary, and
localized, and could be mitigated through the application of good engineering and construction
management practices and with close supervision and monitoring of contractor performance and
consultation with local communities. However, type and nature of impacts vary significantly with
the nature and scale of the activities, locations, and its environmental and social setting, human

behaviors, and time factors. In this context, Sections 4.3 discussed the assessment of the overall
project impacts as well as site-specific impacts of the subcomponents.

(b) Other social impacts
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
64
– 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.
VIWASE – LAVIC Consulting Association
69
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.

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

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
78
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.

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.

6.3 ENVIRONMENT MONITORING PROGRAM
Environmental Monitoring
It is essential to design the monitoring program and monitoring frequency appropriately to be able to
record both the overall performance of the project works as well as the short-term impacts due to
construction activities. The environmental monitoring program will be implemented during
construction at three levels:
Monitoring the level of compliance with mitigation measures,
Community-based Monitoring, and
Monitoring the environmental parameters set out in the EIAs for each of the works.
6.3.1 Objective and Approach
The main objective of the Environment Monitoring Program (EMP) is to ensure that (a) the
potential negative impacts of the project are minimized; (b) the EMP is effectively
implemented; and (c) the EMP is adequate to mitigate the potential negative impacts. Given
that monitoring the implementation of the RP will be conducted seprately, the environmental
monitoring program will comprise (a) monitoring the safeguard performance of the contractor
during site clearance and construction, (b) environmental quality monitoring, (c) monitoring
performance of the Chau Giang WWTP and its potential impacts in terms of water quality,
odor, and treatement of sludge, and (d) monitoring the overall of the EMP.
6.3.2 Monitoring of Contractor’s Safeguard Performance
Three level of safeguard monitoring will be implemented: routine monitoring, periodic
monitoring, and community monitoring as follows:
– Routine monitoirng: The routine monitoring will be made by the Construction
Supervision Consultant (CSC) as assigned by PMU. The CSC will include the
monitoring results in the project progress reports.
– Periodic monitoring (every six months): As part of the overall monitoring of the EMP,
the ESU assisted by the Independent Environmental Management Consultant (IEMC)
will also monitor the contractor performance every 6 months and the results will be
reported to the PMU and the WB.
– Community monitoring: Monitoring by local communities will be conducted following
the Government practices with technical and management support from PMU.
VIWASE-OCI Consulting Association 99
6.3.3 Environmental Quality Monitoring
To ensure an acceptable level of environemtnal quality, monitoring of dust, noise, vibration, air
quality, and water quality will be be made at project specific locations that are likely to be
significantly affected by the construction activities, or requested by local authorities and
communities for specific purposes. ESU/IEMC will be responsible for monitoring of the
program.
Below is a list of the key issues and scope of monitoring that will be considered in the
implementation of the monitoring program:
– Implementation of the Dredge Material Management Plan (DMMP) for all sludge and
similar material excavated from the project work sites: Amount, level of heavy metals,
locations and performance at disposal sites, and impacts on local residents will be
monitored. Outline DMMPs will be prepared during detailed design, and will be used
as the basis for contractors’ dredged materials management plans.
– General Construction Impacts: To include local flooding; traffic management
especially in residential areas; air, noise, and dust levels in residential areas; and water
quality upstream and downstream of construction sites, with specific attention paid to
impact on local residents;
– Water Quality: Water quality near Chau Giang WWTP during the first year of
operation, including opinions of farmers who will be using water from the irrigation
canal that will receive treated wastewater discharge; and
– Others: As agreed with local agencies and communities during the preparation of the
monitoring program.
Tables 6.3, 6.4, 6.5, and 6.6 and provide general guidance on the monitoring program and
estimated cost considerating that the activities will be carried out before construction (project
baseline environment), construction phase (5 years), and during the first year of operation.
Detailed monitoring programs will be prepared during the detailed design stage. An estimated
cost for monitoring is incorporated into the EMP cost (Section 6.6). Many of these
measurements are required by Vietnamese regulations and would need to be done even if not
directly related to expected project impacts.

program has been developed (Table 6-7). This will be carried out by the agencies responsible
for operation of the plant, using their own operating budget. The monitoring results will be
submitted to the City and to the WB. The PMU’s ESU assisted by the IEMC will prepare a
detailed monitoring plan, based on Table 6-7, with the agency responsible for operating the
plant at least three months before construction is completed. The program will also include a
water quality monitoring program which will be prepared and implemented in close
consultation with the responsible agencies. Consultation with the local farmers who are using
water from the existing irrigation area (A46 irrigation area) that will receive treated wastewater
from WWTP will be incorporated in the monitoring program.

6.3.5 Monitoring Implementation Performance of the DMMP
Adverse impacts due to dredging and transportation of bottom sediment from Lam Ha and
Quang Trung Lakes are not expected since the level of heavy metals in these sediment are
within allowable standards. However, this conclusion is based on a small number of samples
tested during the feasibility study. Accordingly, the detailed design will include a
comprehenisve testing program and the development of a DMMP, reflecting the guidelines
below as appropriate.
A guideline for preparation and monitoring of a DMMP
Main environmental and social issues related to contaminated dredge materials are: (a)
Pollution during the transport of the dredged soil from the dredging site to the disposal area;
(b) Potential increase in turbidity and pollution of the water in the lakes/canals during
dredging; (c) Odor and other disturbance to local residents; (d) and Potential misuse of the
contaminated dredged materials for public infrastructure and households. To facilitate the
preparation of a DMMP given that the activities will be carried out in an urban area and/or
existing water body that may be used by other water users, the following aspects should also
be considered:
Assessing the quality of the sediments. The assessment will be carried out to confirm that the
sediments will not include large amount of environmentally harmful materials such as heavy
metals and/or other toxic substance. If these materials are found to be more than the thresholds
stipulated by the national standards, a special disposal plan should be prepared with a monitoring
plan. The special disposal plan should also set out a program to protect the nearby community
residents from using the disposed dredged materials for house construction or gardening. The
bottom sediment/sludge samples will be undertaken for analysis for key pollutants according to
the national standards. The sampling and analytical methods should be in line with the
Government regulations while the sampling locations will depend on the risk level for each
specific site:
VIWASE-OCI Consulting Association 103
Identifying the available land for disposing the dredged materials. The plan must identify the
landfill sites and/or land that could be appropriate for the disposal of dredged materials in line
with the level of risk associated with it. Public land, land for construction of rural roads, public
works, private land, etc. may be used, with an agreement with the project affected households. If
the risk due to contamination of sludge is high the sludge materials will be disposed of at Nhi Phu
sanitary landfill which has been in operation.
Preparing for a dredging and transportation plan. Dredging procedures and transportation plan
will be prepared outlining: (a) methods of dredging (pipeline, water pumping before digging, etc.)
and uploading to the disposal area and/or transportation vehicles, and/or temporary storage site. If
trucks are used, indicate proposed route of the transport from the dredged site to the disposal area,
(b) time of operation, (c) type of vehicles/trucks and proposed measures to reduce the leakage of
the dredged materials from the transport trucks, (d) contractors’ responsibilities for cleaning the
roads and carry out remedial works if necessary, and (e) a communication plan for the nearby
communities including contact number for possible complaints.
Temporary storage/disposal for uncontaminated sediment/mud. As the dredged materials are in
the state of mud at first before settled for 24 to 48 hours. All drainage water from disposal land
shall be driven to the drains and discharged back to the canal/lakes. For areas with highly
contaminated with organic material and create odor, dredge material/sludge should be hauled by
close tanker outside the construction site as soon as possible. For bottom sediment with low
contamination of organic materials, the dredged sediment will be transported to a containing area
which is appropriately located and properly design with an adequate size. A monitoring plan for
tracking the disposal of high contaminated materials will also be prepared.
Identifying key area and/or receptacles (business, schools, public services, etc.) that are sensitive
to dredging and transportation. The DMMP shall carry out an inventory analysis on the possible
affected local businesses, access to water, and transportation (mainly due to the dredging) and
provide a plan to mitigate and/or compensate for the disturbances. The plan should include all
measures necessary to avoid impacts on local transportation and water supply access to local
residents as much as possible.
Identify other key water users. If dredging occur in water bodies (such as lakes, rivers/stream)
where there are potential other water users that may be affected by dredging, prepare a water
quality monitoring plan with specific stations and parameters that could be used to monitor the
potential impacts to the water users. Priority should be given to monitor the areas that are sensitive
to change in water quality (high suspended solid (SS), low pH, high BOD or COD, high salinity,
etc.) especially where the water is used as a source of water supply for domestic and agricultural
uses. In areas where dredging may cause negative impacts to these water users, respective
subproject owner is required to inform/consult them and develop a series of actions to address
their concerns, including conduct water quality monitoring in the DMMP.

6.3.6 Monitoring Effectiveness of the EMP
The ESU assisted by the IEMC will monitor performance of the DMMP aspects of the
EMP implementation during the detailed design/bidding stage as well as during construction
and first year operation of the facilities to ensure that (a) appropriate dredging and disposal of
sludge is properly carried out,in accordance with the DMMP, (b) traffic management is
adequate and the level of impacts are acceptable (no complaints or outstanding cases), and (d)
the potential impacts of the WWTP and pumping stations on water quality and odor are within
the standard and acceptable to local residents/farmers who are affected. Results are to be
properly kept in the project file for possible review by the PMU and the WB. Cost for the
monitoring will be part of the PMU cost.

– Impacts on water quality in Lam Ha and Quang Trung lakes
– Consultation with local communities in key project areas (Quang Trung, Lam Ha, Me
Noi, and farmers in existing irrigation area (A46)
6.5 CAPACITY BUILDING PROGRAM
6.5.1 Technical Assistance support for the implementation of safeguards
An assessment of safeguards implementation capacity of existing PMU staff indicates that
PMU staffs have limited knowledge on WB safeguard requirements as well as limited
knowledge of environment and social issues. Such lack of capacity represents a risk to project
implementation of safeguards requirements contained in the EMP and, as required by the WB
policy, is to be addressed through capacity building. Therefore, it is proposed to provide
capacity building through technical assistance that will support the PMU during the
implementation of the safeguards requirements. The technical assistance will provide the
necessary technical support the PMU in its work with contractors as well as other entities
involved in the implementation of the EMP.
The scope of the technical assistance would cover support from experts and training that
would cover both the knowledge on safeguards requirements and procedures for the project as
well as training that covers both specific knowledge on safeguard procedures and requirement
VIWASE-OCI Consulting Association 111
for the project staff, consultants, and national contractor would be important. This would
include, for example, assistance in the preparation of documents and implementation of
training program on environmental management and environmental monitoring for
contractors, CSC and relevant staffs of PMU (environmental staffs and coordinators of
packages) to do their tasks. It would also include assisting the PMU’s environmental staffs
with the review of contract documents on the bidding packages for construction items of the
project to ensure compliance with environmental protection policies and impact mitigation
and monitoring requirements as well as provide general environmental guidance as requested
by the PMU to enhance overall project implementation and performance.
Given the nature, locations, and scale of construction, it is anticipated that the safeguard
technical assistance support and training will be provided at least during the first 3 years of
the project implementation. The WB safeguard specialists will participate in the capacity
building in particular in the training activities as appropriate.
6.5.2 Training programs proposed
Table 6.9 below provides examples of the basic trainings for safeguards during project
implementation. The training programs will be developed and delivered by the Technical
Assistance team for the implementation of safeguards for the PMU training. The PMU/IEMC
with the support of the Technical Assistance team for the implementation of safeguards will
provide the training to contractors, CSC and other groups.
Other more specific and tailored training will be developed and agreed upon between PMU,
IEMC and the Technical Assistance team for the implementation of safeguards during project
implementation based upon an reassessment of needs and the status of safeguards
implementation.
– Target groups for the training: include PMU staff, ESU staff, field engineers, CSC,
construction contractors, local authorities, and community representatives in the project
area. Training of workers and drivers is the responsibility of the contractor.
– Training schedule: At least 1 month before the construction of the first contract; the
training can be adjusted in line with the implementation schedule of the
subproject/contracts.
– Training frequency: The basic training programs proposed in Table 6.9 will take place every
six months on a yearly basis and its content updated and adapted to implementation issues.
Training frequency and content will be reassessed during implementation depending on
needs. It is foreseen that the training program for PMU staff will continue until year three of
implementation. Three days of training for CSC and contractors are also planned to take
place twice a year on an annual basis for at least two years.

6.6 ESTIMATED EMP COST
Table 6.10 provides an estimated cost for EMP implementation (excluding the resettlement
cost and RP and EMDP independent monitoring). The EMP cost3 will comprise (i) cost for
implementation of the mitigation measures by contractor, (ii) cost for supervision by the CSC,
(iii) cost for environmental monitoring consultant (IEMC) (iv) monitoring of environmental
quality (v) PMU safeguard management costs, including technical assistance support for the
implementation of safeguards and training. Costs for the implementation of the mitigation
measures during construction will be part of the contract cost while cost for monitoring of
SEMP by the CSC is provided for in the construction supervision contracts. Costs for PMU
operations related to EMP are provided for in the project management budget of the PMU,
including basic safeguards training and allowances for people who participate in the
monitoring program. After project completion, the cost for environmental monitoring of the
constructed facilities will be funded by the cities’ operations and maintenance budgets.
It is noted that the attendance of community representatives in EMP implementation is
voluntary, and without salary. Hence, to encourage the participation of community members,
the cost for materials, equipment used for monitoring and rewards for people who are voted to
implement monitoring are taken into account. Following decision No. 80/2005/QĐ-TTg dated
18/4/2005 of Prime Minister on regulations of community investment monitoring and joint
circular for guidelines of decision implementation No. 80/2005/QĐ-TTg “cost for supporting
the investment monitoring of community in commune/ward are calculated in cost estimation of
commune/ward fatherland front and are guaranteed by commune/ward people’s committee
budget; cost for propagation, training courses, guiding, closing of community investment
monitoring at district and provincial level are calculated in cost estimation of commune/ward
Fatherland Front and are guaranteed by commune/ ward people’s committee budget”.
Table 6.11 provides an estimated IEMC and environmental quality monitoring cost in line
with the country practices for reference. However, the final cost will be updated during the
detailed design.

7.2. PURPOSE OF COMMUNITY CONSULTATION
Public consultation is part of the environmental assessment in the Project. It is carried
out in co-operation by the Project owner, Designing consultant, Environmental consultant,
local authorities, and residential communities in area being subjected to the project. Outcome
of such consultation shall be used to assess designing plan, and propose minimizing solutions,
and express the public’s supporting during the course of carrying out the project.
The purposes of community consultation
- Sharing all information about items and expected Project activities with the community
living in the project site and stakeholders.
- Understanding opinions and public care for the Project, especially those who are
directly impacted by the Project construction and operation. Based on this, public cares
can reanably be settled during the course of setting up the Project, and selection of
designing solutions.
VIWASE-OCI Consulting Association 116
- Attentively listening to public opinions and their caring toward the Project, in which
direct impacts given to daily life of the community will be specifically taken care of.
- Settling conflictions, which is arisen among public proposals for environmental issues
and delays in implementing the construction schedule of authority bodies.
- Giving logical and lawful confirmation in respect of the authority’s decisions in
meeting reasonable demand of residents, and considering public proposal and the
authority bodies.
- Understanding major difficulties that residents living in area being subjected to the
Project are taken care of.
- Initially, public consultation activities also help to consider the issues and concerns of
the community in the process of project design in order
to increase confidence and support for the project. In this way, effective public
consultation can reduce the risk of conflicts and delays in project
implementation process and can improve the overall sustainability of the project.
The principle of public consultation in the EIA:
- Information dissemination: Information about the efficiency of the project should be
communicated to the local community and affected groups under several suitable
approach forms. Needing to conduct communications from early stage so that the
people have time to consider problems related the EIA process and form their views.
Provided information need clearly to define the affected area, both the advantages and
disadvantages of proposed activity.
- Gathering information: It is necessary to discuss and exchange with the concerned
competent authorities of the Government and community representatives (People's
Committee,Council, Investment Supervisory Board and community’s organization); the
local may be affected by the project and other groups enjoy benefits (like non-
governmental organization in the local) to know their views and their contributions for
the projects and the works of EIA.
- Intergating in the evaluation process: The views and concerns of the community and
stakeholders should be considered when: (1) Identify key issues need consider in
evaluation; (2) Assessment and predict the effects and risks directly / indirectly may
happen from the project; (3) Assess the impact and risk level; (4) Develop monitoring,
management and mitigation programs appropriately. Ideally, the consultation processes
should be started from the stage of determining the scope of EIA
- Coordination: The public consultation activities should be coordinated authorities
related in the region and being affected by the project and they should be notified soon
about any proposed changes in the operation of the project.
- Connecting people in a dialogue: Needing to use the suitable tradition method in the
process of public consultation to bring people into dialogue, focusing on the sources of
information and two- dimentional ideas between the project and stakeholders
7.3. PUBLIC CONSULTATION
A – Methodology:
VIWASE-OCI Consulting Association 117
The methods of public consultation are often used including quick assessment
method having the participation and consultation of stakeholders, using techniques
such as:
- Community meetings, group meetings and focusing group discussions
- Also, conducting investigation and interviewing quickly some households along
assessment route, finding out thoughts, aspirations and their ideas about the project
by issuing questionnaires.
Medium cities development project – Phu Ly subproject, Ha Nam province after being
screened then it was classified as the project of Category A by the complexity and
multidisciplinary impact. In the feasibility study phase of the project, the ODA project office
about investment for Phu Ly and consultants groups (WIWASE – OCI Association) has
collaborated with leaders of the communes concerned to implement more campaigns to
disseminate information and public consultation. The campaign is divided into two batches
with several rounds in the communes and wards in project area.
The 1st public consultation was held during the first phase of Feasibility
Study preparation and right after the draft terms of reference of environmental impact
assessment. The missions deploy campaigns to disseminate this information about two
round in the proposed project area, specially:
Round 1: Running from on May 23, 2010 to on May 31, 2010: This information
disclosure was integrated as a part of general socio-economic survey under the Project
(conducted during the last week of May 2010). The implementation contents during this phase
included project information dissemination, questionnaire-based interviews with a sample of
approx. 10% households living in the proposed project area including 3 wards and communes
of Phu Ly City: Liem Chinh, Quang Trung and Lam Ha; (Table 7-1)
Participants: representatives of local authorities (commune level), local Unions (e.g. Women’s
Union, Youth Unions, etc), local representatives (Fatherland Front)
Round 2: during the period from July 1st, 2010 to July 5th, 2010, Consultants organized
additional meetings to consult and seek opinions of local authorities and residents in
wards/communes in the Project site, including Lam Ha, Tien Hiep, Liem Chinh Communes,
Quang Trung Ward, and Tien Hai Commune. (Table 7-1)
Participants: project affected households (PAHs), representatives of local authorities

CHAPTER 8. CONCLUSIONS, RECOMMENDATIONS
CONCLUSIONS
- EIA report identified and evaluated almost all environmental impacts in all stages of
the project, from design stage to construction and operation stages of the project.
- During EIA process, impacts are evaluated by theoretical formula and experiment,
statistical figures and experiences of similar projects. However, there is no evaluation
method which is absolutely accurate but the quantitative method measures relative
impact. During project implementation process, it is required to make suitable
adjustments so as to minimize negative impacts to the environment.
- Almost all impacts in pre-construction and construction stages are temporary and
short-term ones. These concentrate around the site in the city or on transport routines
and landfills. The most remarkable impacts in construction stage are dust and traffic
jam.
- Impacts in operation stage are potential and long-term ones. These are impacts on run-
off water environment of Chau Giang River and Nhue River.
- Almost all proposed mitigation measures of negative impacts and prevention and
response measures of environmental risks and incidents are extremely feasible.
- Contents of EIA report are in compliance with current requirements for environmental
impact assessment of the Vietnamese Government as well as of the World Bank.
- The report is one essential document submitted to State organizations in order to
identify the position and the scale of the Project and call for investment.
- The project of Medium Cites Development Project in Vietnam, Phu Ly City
subproject, Ha Nam province is a feasible project and in conformity with the planning
orientation for socio-economic development of Phu Ly City. It satisfies demand for
the need to develop socio-economic conditions in the area as well as to improve the
environment, hygiene and living conditions of the populace.
- The Project construction might cause some negative impacts on the society and the
environment in the case where there is no solution for the need to co-ordinate between
the investment for operation of transportation construction and the Master Plan
(which provides the framework and details to limit the impacts on the society and the
environment).
- From the preliminary analysis of the collected environmental data, it is clearly shown
that river and lakes in area being subjected to the Project appear to be polluted.
Therefore, water quality of these river and lakes shall be improved once the upgrading
works are carried out. The improvement of water quality helps eradicate risks of
diseases caused by water sources which will improve the hygiene conditions and
health of people living along canals and ditches.
- The Project Owner shall seriously carry out the plan of mastering pollution as stated
in this Report in order to satisfy the Vietnamese Standards on environment. Plans on
VIWASE-OCI Consulting Association 131
mastering pollution and curbing disadvantageous impacts of the Project to the
environment being presented and recommended in the Report are feasible, and satisfy
requirements of the Vietnamese Standards on Environment.
- Environmental monitoring program shall be immediately carried out after the State
gives its approval and issues construction and operation licenses. Monitoring data
shall be stored and be legal grounds for the implementation of the Law on
Environmental Protection of Vietnam.
RECOMMENDATIONS
- During project implementation process, PMU requests Ha Nam People’s Committee
to instruct related departments and local administrative agencies to provide
cooperation coordination during project implementation.
- In land clearance and resettlement, PMU needs support and coordination of PCs and
Fatherland front at wards and communes in project area and functional agencies in
order to ensure efficient and smooth acquisition of land for project execution.
- In environmental protection: PMU needs coordination, support and opinions of Ha
Nam Department of Natural Resource and Environment in order to have good
performance during project implementation. In particular, investment scale of the
Project excludes resettlement section, investing the tertiary drainage system (which is
in other project), PMU suggests People’s Committee of Ha Nam, Phu Ly City to
implement resettlement, connecting tertiary drainage system in line with set schedule
so that the project’s surface is implemented as planned and the sewage is transmitted
to treatment station or Quang Trung lake.
- For traffic safety: PMU needs coordination and support of Department of
Transportation, Traffic Police, local authority to effect traffic diversion and resolve
traffic jams.
- For dust management and site cleaning: PMU needs support of Phu Ly Environmental
Company during implementation process.
