I. INTRODUCTION
A. Subproject Rationale
1. Sustainable Rural Infrastructure Development Project in Northern Mountain provinces (SRIDP) is being implemented through a sector loan from Asian Development Bank (ADB). Ministry of Agriculture and Rural Development (MARD) is the executing agency for the sector loan. SRIDP coverage is 15 mountainous provinces in northern Vietnam (Bac Giang, Bac Kan, Cao Bang, Dien Bien, Ha Giang, Hoa Binh, Lai Chau, Lang Sơn, Lao Cai, Phu Tho, Son La, Thai Nguyen, Tuyen Quang, Vinh Phuc, Yen Bai).
2. While the poverty levels throughout the country had been significantly reduced as results of development efforts; the statistics in mountain provinces above had indicate rather slow improvement during the last decade (47% in 2002, 32.3% in 2006 and 27% in 2008)
1. Part of the
problem is due to the inadequate access facilities, social services, and commercial opportunities. It is for this reason that GOV and ADB had pursued the SRIDP to provide sustainable access facilities in these poverty stricken mountain provinces. These infrastructures include rural roads, public markets, irrigation and water supply facilities. As a part of the SRIDP, the Sub-project “Revetment to protect banks of Cau river, Cho Moi district” will be implemented in Bac Kan province
B. Subproject Objectives
3. The subproject objective is to construct a revetment for protection of the stream banks for 90 ha of agricultural land; protect 500 m of rural road, a kindergarten and property of 50 households, which in-turn protects the lives of people living in two subproject communes, Thanh Mai and Cao Ky, and therefore allows the continuation of economic development and poverty alleviation for these communes.
C. Project Alternatives
4. Efforts to minimize the adverse social impacts of the Subproject include minimizing the land required for building concrete revetment. Likewise, the need for borrow pits in the construction of embankments will be minimized and the Subproject will, whenever feasible, use materials from stream bank excavation.
5. Initial Environmental Examination (IEE) has been prepared to meet the Social Policy Safeguards requirements of ADB

dimension 2x1x0.5m and pipe 100, 1m high.
2.6 Revetment wall
- Height of wall
- Thickness of top and wall toe
- Revetment foundation
- Structure
There will be 3 types of revetment wall that will be installed
corresponding to terrain at each stream bank section as follow:
- Vertical concrete wall revetment: Reinforced concrete structure
embankment placed on concrete foundation 40cm thick. This kind is
installed for revetment of stream bank with 3m- 4.3 m height of wall.
- Skew roof revetment: Revetment has skewback m=1.5, panels
that are arranged closely and placed in embankment frame system
creating square with length of 30.8m. This kind is applied for stream
sections that are eroded causing steep slope stream bed. .
- Stone wall revetment: Stone load-bearing wall placed on concrete
foundation is applied for 2-2.5m high wall of stream bank.
2.7 Stone steps down to stream 14 steps to get down from stream bank top to stream bed (5 steps
on revetment for structures installed in Thanh Mai commune, and 9
steps on revetment for structures installed in Cao Ky commune) are
combined with side drainage ditches 1m wide on both left and right
side of the revetment.
2.8 The length of the drainage works Side ditch with a dimension of (30x30) cm, made of concrete
structure 150# is arrange on revetment top on the side next to the
adjacent agriculture field, and along the revetment alignment.
Side drainage ditches with a width of 1m concrete structure 150#
are designed in shape of combination with up and down steps
2.9 The width of clearance ground site - Acquired land area for construction: 23 127 m2
2.10 Water bodies - Suoi Nhanh stream traversing Thanh Mai commune has length of
10km, runs mainly through the stream banks of Na Pen, Ban Phat,
Ban Pa, Ban Piai hamlets 4km long. This stream has a narrow
cross-section, strong discharge which causes severe bank erosion.
Annually, 5-10 m of stream bank is eroded and deposited to other
areas along the waterway.
- Suoi Nhanh stream traversing Cao Ky commune flows into the
Cau river has a lot of meanders. In recent years, under effect of
climate change, the stream flow has increased thus causing bank
erosion eventually leading to the damages in adjacent agricultural
lands of Hua Phai ham let and Choc Tong hamlet of Cao Ly
commune on both side of stream bank.

Table 2: Description of ground environment
Description Subproject data
1. Subproject location
1.1 Communes: Thanh Mai and Cao Ky
1.2 District: Cho Moi
1.3 Province: Bac Kan
1.4 Geographical
location:
Thanh Mai commune: 105046’15’’ longitude – 22
001’20’’ north latitude
Cao Ky commune: 105049’50’’ longitude – 21
045’50’’ north latitude
2. Natural environmental conditions
2.1 Air quality Sub-project will be installed on two waterways located in two rural mountainous communes of Cho Moi district were the adjacent areas are sugarcane plantation, maize fields, and some sparse residential areas. Air quality of the sub-project area is relatively clean.
2.2 Noise and
vibration
National Technical Regulation on Vibration 27:2010/BTNMT contains noise and vibration
standards prescribed for residential and institutional areas. On the basis of these standards,
measurements were made at the study area and the results showed that the measured ambient
noise is from 49.6 dB to 61.7 dB, which is below the prescribed limit of 70dB. Likewise
measured vibration levels are from 0.01 – 0.03 m2/s, which is lower than prescribed limit of
0.055 m2/s (Source: EIA Report for subproject of Revetment protect bank of Cau river, Cho Moi
district, Bac Kan province)
2.3 Climate and
natural disasters
Rainy season is from May to October, dry season lasts from September to next April.
Average annual rainfall reaches 1,791 mm. The highest rainfall intensity occurs in July, while
the least is during December. Total rainfall in rainy season accounts for 75% - 80% of the
annual total.
Flood occurs in the area annually resulting in stream bank erosion, as well to the adjacent
agriculture lands, causing damages to the crops, trees and other livelihood of the local farming
community on farm land adjacent to the stream bank.
2.4 Topography and
soil
- Revetment alignments in Thanh Mai commune is to be installed on the waterway crossing the
agricultural fields of the hamlets of Na Pen, Ban Phat, Ban Pa, Ban Pjai and the centre of
commune which is a large area, along the valley having an even and flat terrain. The valley may
have been formed by the deposition of alluvial soil that had been eroded from the nearby
mountains.
- Similarly, the revetment alignments in Cao Ky commune are to be installed on the banks of
Suoi Nhanh stream that cross the agriculture fields of Hua Phai and Chooc Tong hamlets as it
flows to the Cau River. The terrain is mainly low hills. The walls of the two stream banks are
low, with average height of 2m to 4 m and follow a winding pattern.
2.5 Water bodies - Suoi Nhanh stream traversing Thanh Mai commune has length of 10km, runs mainly through
the fields of Na Pen, Ban Phat, Ban Pa, Ban Piai hamlets 4km long. This stream section has
narrow stream-bed, large discharge causes severe erosion. Annually, 5-10 m of stream bank is
eroded and deposited to the other bank.
- Suoi Nhanh stream traversing Cao Ky commune flows into the Cau river is winding In recent
13
Description Subproject data
years, under effect of climate change, the flow has changed causes stream bank erosion and
damages agricultural land on both side of stream bank.
2.6 Ground water People in the sub-project study area mainly use the dug-well with household scale, get water for
domestic purpose. Average depth of these wells is from 15 – 20 m.
2.7 Water Quality Monitoring results of water samples taken, showed that the water quality parameter values are
within the prescribed limit of QCVN 08:2008/BTNMT (National technical regulation on surface
water quality). Some monitoring samples showed BOD values exceeding prescribed limits of
about 0,4 – 2,6 mg/l, it means that there is sign of organic pollution, but at low level, the stream
is able to clean itself without intervention. (Source: Environmental impact assessment Report
for subproject of Revetment to protect bank of Cau river, Cho Moi district, Bac Kan province)
As observed, there is no sign of external contamination as dirt, sewage, and detectable odors
such as fishy, foul, and rotten at the water ways traversing the sub-project area.
2.8 Natural Hazards In rainy season, water from streams pours quickly, gathers in tributaries causing local
inundation. Flood occurs in the area annually causes stream bank erosion that eventually
damages the adjacent fields, which is the main source of livelihood of local people.
2.9 Terrestrial flora
and fauna
- There is no wild animals found within the study area that are listed in Red Book, that should be
protected.
- Terrestrial fauna includes domestic animals (buffalo, cow, pig, chicken, etc.) and terrestrial
wild life (sparrows, black starlings, lizards, geckos, insects and worms, etc.)
- The dominant terrestrial floras in the subproject area are paddy rice, sugarcane, acacia, food
crops, soybean grown by the local farmers. Other species include scattered planted timber
trees (acacia mangium, melia..) and some fruit-bearing trees (banana, peach, plums…) along
the access roads, and cash crops (beans, peanuts, maize, etc.), shrubs, grasses, and other
common weeds. No rare and valuable plants that should be protected are found within the
study area
2.10 Aquatic flora and
fauna
There is no endangered species found in the study area recorded in the Red Book that should
be protected, including:
- Aquatic flora: mostly algae, mosses, and water plants, other phytoplankton, and no rare
aquatic plants
Aquatic animals: including fresh water fishes (carp, silver carp, etc.), shrimps, snails, etc., but
no species were identified to be in the protected fauna list.
2.11 Protected areas There is no protected area found in sub-project area
2.12 Natural
characteristic of the
basin
The revetment in Thanh Mai commune: Catchment area is of 50 km2, length of main river is of
10 km
The revetment in Cao Ky commune: Catchment area is of 20 km2, length of main river is of 8
km
Erosion on Cau river is caused by topography, winding characteristics of the waterway,
changes on slope of stream bed in each segment, unequal stream cross sections, and
concentrated rainfall during the rainy season.
3. Environmental and social conditions
3.1 UXO There are no UXO left in the subproject area. This problem had already been solved in the
previous construction.
3.2 Land use Total land area of 2 communes of Thanh Mai and Cao Ky is 10,085.8 ha, in which the size of
agricultural land is 783 ha, forest land is 8,760 ha, land for other purposes and unused land is
542.8 ha.
Total agricultural land area of hamlets of Na Pen, Ban Phat, Ban Pa, Ban Pjai, Hua Phai, Choc
14
Description Subproject data
Toong, traversed by revetment route is of 95.9ha. Average area loss by bank erosion is
1.007ha in Thanh Mai commune and 0.52ha in Cao Ky commune annually.
3.3 Residential lands
traversed
There are no residential areas established along the stream bank on which the revetments will
be installed. There are however scattered residences along the public road, which may be used
by the contractors to transport materials and waste. These residences are found in the hamlets
of Trung Tam, Ban Pa, Ban Phat, Roong Tum, and Ban Ty, in Thanh Mai commune; as well as
Na Toong hamlet in Cao Ky commune.
3.4 Rural
infrastructure
There is a 100m long inter-commune road, and a 400m long inter-hamlet road located near the
streams, as well as a kindergarten school building. These structures will not be adversely
affected by the revetment construction but are expected to be among the facilities to be
protected by the subproject.
The Inter-communal road and inter-village road can be used as access road for material
transport to the worksite during construction stage in 12 months.
3.5 Agriculture - Major agricultural crops of 2 communes in sub-project area are rice, maize, peanut, soybean,
sweet potato. Fruit trees include mandarin, persimmon, and bananas.
- There is also limited surface water resources in subproject area, and so the local people had
not engaged in any aquaculture activity.
3.6 Population (direct
and indirect
beneficiaries)
- Population of Thanh Mai commune is 2,563, total of number of households is 692, and
average density is 62 person/km2
- Population of Cao Ky commune is 2,906, total households is 716, and average population
density is 49 person/km2
- Direct beneficiaries from the subproject are 694 paddy rice farmers in Thanh Mai and Cao Ky
communes, who have paddy rice fields threatened by stream bank erosion annually.
3.7 Ethnic minorities Tay and Nung group of ethnic minority primarily live in locality accounting for 80%, Kinh group
makes up 20% of total population.
3.8 Livelihood and
employment
- Majority of direct and indirect beneficiaries from the subproject are farmers who live in poor
condition. Poverty rate in Thanh Mai commune is 39% of all households (270 households), the
one in Cao Ky commune is 35% (255 households).
- Average income per capita is about of 4 - 6.6 million VND per year. The middle-income
households have besides rice farming, are also engaged in cattle raising, fruit trees growing or
intensive rice cultivation. The poor households are mainly engaged in monoculture (paddy rice)
for food, have no capital to raise cattle; elderly, with disabilities, and have low fertility soil. This
condition is aggravated by the poor road condition, so that they are not able to plant and market
high-value crops.
3.9 National/ Cultural
heritage
There is no cultural heritage in the project area.
3.10 Public health Most diseases usually occur in locality during the rainy season, but are always under control
through medical attention by the household with assistance from the health station such as:
diarrheal, typhus, dysentery, varicella, and others. There are also other upper respiratory track
diseases such as pharynitis, sinusitis, flu and others.
3.11 Beneficiaries The subproject installation will benefit directly 694 farmers cultivating paddy rice in the 2
communes of Thanh Mai and Cao Ky, Cho Moi district, through ensuring continuous agricultural
production thru the protection of the stream banks and adjacent farm lands at critical sections
of the waterway, that are highly susceptible to erosion causing by the annual flooding.

IV. ENVIRONMENTAL IMPACT SCREENING
7. An environmental impact assessment is a study of the possible positive or negative impact that a proposed subproject may have on the environment, consisting of the physical, biological and socio- economic sectors. To identify and evaluate the impacts of any one subproject, there are various methods commonly used for environmental impact assessment such as check-list method; matrix method; the Battelle environmental evaluation system; and cost-benefit analysis method.
8. In this part of report, the consultant used the check-list method, which is widely used and generally sufficient for small scale projects having Category B classification.

Location: Farmlands located along the alignment of
the revetment structures.
Scale: The impact was assessed in the REMDP as
not severe since none of the Ahs will require
relocation and none will have more than 10% of their
productive land and assets affected. The owners
receive compensation for affected land and assets on
the land based on the approved REMDP.
2. Impacts in construction stage
2.1 Erosion or sedimentation caused by land clearance or land excavation or filling
Yes Low Negative Temporar
y
During the construction, soil erosion and soil and
stone falling into farm lands may happen. As a result,
the subproject adversely impacts on agriculture
production as non-fertile soil from excavated
embankments may cover farmlands, thus reducing
the effective area suitable for crop production, and
eventually reduces agriculture yield and farm
incomes. Similarly, fallen building material such as
sand, stone may increase turbidity of water and cause
reduction of water conveyance capacity.
Deteriorated water quality is not good for local people
to use for domestic activities, such as bathing and
washing.

transport of materials to and from the site may cause
soil, rock and other debris to drop from transport
trucks to areas near the streams. These fallen
materials may be washed back into the stream by
surface water run-off produced by strong rains during
the rainy season.
The impact is evaluated to be small since much of
the soil for use as embankment backfill material will
come from the excavated soil, so that most of these
(spoils) do not need to be transported out. Surplus
excavated soil of 22.324 m3 will be transported to
dumpsite close (500-1000m) to the work site.
In other hand, the impact (sedimentation of
waterways) may increase the turbidity of water only
because of sedimentation by fallen soil and rock, and
not organic pollutants. Local people use stream water
only for bathing and washing, and not for drinking.
The stream is able to clean itself after a few hundred
meters downstream without intervention. After
completion of the construction works at each section,
the local people can use stream water as before.
Location: Cultivation areas and water in Suoi Nhanh
stream around the constructed revetment section
Duration of impact: 18 months of construction
period.
2.2 Leakage of oil and lubricant from construction equipment pollutes soil and water environment
Yes Minor Negative Temporar
y
These petroleum-based hazardous substances can
leak from construction vehicles and equipment during
their operation, and/or during maintenance work, and
the pollutant can spread to cultivation lands around
construction site, causing negative effects to plants or
affecting crop productivity.
Contaminants during subproject construction could be
carried away by rain and surface-water to flow into
the Suoi Nhanh stream and cause the deterioration of
its water quality and affect the aquatic environment in
it
However, the estimated number of construction
vehicles and equipment are few so the probable
amount of petroleum leakage may not be significant
to affect the adjacent lands. Similarly, construction
substances in the form of paints and thinners are
normally placed in cans to avoid unnecessary
spillages; and are to be placed in sealed and roofed
storage areas. Thus, this is assessed as insignificant

Yes Minor Negative Temporar
y
- Total of excavating soil: 35.478 m3
- Total of filling soil: 13.154,1 m3
The transporting of construction materials and waste
thru the inter-hamlet road which are mainly unpaved
roads, is a major source of dust, noise, vibration and
emission which affects the health of local people’s
living along and near the said access facilities,
especially in the hot and dry days.
The same impacts are felt in construction site due to
activities of construction vehicles, machineries such
as excavator, compactors, and concrete mixers, etc.
that can affect workers’ health.
The impact is evaluated to be small since much of the
soil for use as embankment backfill material will come
from the excavated soil that does not need to be
transported out of the construction site. Surplus
excavated soil of 22.324 m3 will be transported to
dumpsite with close distance (500-1000m) from work
site. Distance to transport material from storage, yard
to site is minimal ranging from 400-600m.
As the subproject is located in rural area with sparse
population density, and covered with much
vegetation, these factors will either absorb the noise
and vibration, or easily dissipate the dust and
gaseous emissions. Within the subproject area, the
terrain is sloping in most areas, open, well ventilated
and covered with vegetation. Noise and gaseous
emissions generated by construction vehicles and
equipment can easily be dissipated. Similarly, there
are no residences near the subproject site (DIA &
SIA) so noise from a few units of construction
equipment operating during daytime will not be an
issue. It is only the low density residential areas along
the short transport route (500-1,000m) at Thanh Mai
commune to be taken by the trucks that will be
affected. However, considering the relatively small
volume of spoils to be transported, the number of
trucks will also be limited.

to flash floods
occurring during
the rainy
season
Yes Moderat
e Negative
Temporar
y
If the construction of the revetment, most especially the earthmoving activities (i.e. excavation, backfilling, compaction, etc.) and installation of revetment structures coincided with the rainy season, it Is possible that flash floods caused by strong rains may inundate the stream channel on which the works are being conducted. The sudden rise in water-level in the stream in combination with strong flows can extremely dangerous to the unfinished structures and workers. Under this extreme situation, construction equipment and personnel may be caught in the flood, and it is most possible that damages may occur on the structures, equipment and injury to workers may arise. Although flash floods in mountainous areas are often
characterized by their short duration due to
concentrated volume of rain that falls, however this do
cause great destruction due to steep gradients along
water ways. However, the sub-project area is
fortunate to be located in an areas having even and
flat terrain between low hills, average height of river
bank is of 2m to 4 m and sinuous winding, so that the
flood waters ability to cause damage on the
revetment works by is not probable. Besides, the risk
exists only during the rainy season and so proper
scheduling is necessary to program all critical works
to be done during the dry months to help ensure
continuous work and safety of workers. In addition, it
may take some time for run-off from strong rains that
fall on the watershed catchment area to reach the
construction site, so equipment and personnel have
enough time to move to safe area. The impact is
considers as temporary and insignificant
2.5 Impact on terrestrial and aquatic flora and fauna

Sources: - During the process of mixing, and pouring
concrete on the revetment walls, wastes fall on the

- Surface water run-off from rain can carry oil
spillages and other petroleum products from
construction equipment and vehicles into the stream
causing water pollution, that may directly affect the
aquatic organisms.
- Among the pollution effect is the Increase of turbidity
in the water that prevents the penetration of light
affecting the photosynthetic functions of the aquatic
flora. Similarly, fish and other aquatic resources that
use their sense of sight to look for food, may not be
able to survive in the area. These water quality
sensitive fishes are forced to move to other areas
leading to reduce density of aquatic creatures living in
the stream segment within the construction area.
The impact of turbidity affects aquatic ecosystems
occur only 18 months during the construction
process. After project is completed, it will return the
same habitat for plant species. Moreover aquatic
plants and animals living within the Suoi Nhanh
stream are mostly moss species, crabs, snails and
other freshwater species common and abundant in
the North so this impact is not significant
For concrete pouring into the adjacent farmlands,
actually much of the construction work most
especially the installation of revetment are manual in
nature, and so small concrete mixers will be deployed
in the area of which concrete spillages are expected
to be minimal.

Domestic solid wastes generated from the construction site are mainly plastic bags, paper, packaging, leftover foods and others. It is estimated that about 60 workers deployed for the whole construction period will generate about 12kg of solid wastes per day. In the mountain area with high demands of livestock, the redundant foods and edible organic waste can be used for cattle feed. Arrangements will have to be made with the livestock growers to collect the food scraps, else, these refuse will be deposited of in the designated disposal area. Therefore, wastes generated from worker’s camp are insignificant Domestic wastewater is mainly from cooking, washing and sanitation activities, containing organic substances, detergents, nutrients, minerals and many pathogenic microorganisms such as E.coli, samonela.

The number of workers for construction activities is
about 60. The presence of these migrant workers,
mainly are men, may generate some of impacts as
follows:
- Positive: Workers from other provinces who come to live in the subproject area can promote cultural exchange, provide service and trade activities in the locality. - Negative: conflicts between migrant workers and
local people may happen due to cultural differences and a possible rise in social evils such as theft, robbery, prostitution, etc. may occur. However, the workers would stay only for short period of time because of section construction approach, and the strict employment regulations for workers required from contractors, will ensure that negative impacts is negligible.

travel most especially during harvest and marketing of
produce; and increase the risk of vehicle accident.
- The impact can be considered minor for the
following reasons: a) Only a short segment of the
stream will be have revetment works, so local
residents will simply move slightly upstream of the
subproject location to do their domestic activities; b)
there were no irrigation facilities (pumps) observed
along the stream section where subproject revetment
will be installed; c) the residential houses along the
transport route is sparse; d) peak traffic conditions is
during the harvest season which occurs only twice a
year and so construction activities can be schedule to
avoid these times; and e) the impact will only be felt
during the 18 months construction period.
Location: Section of Suoi Nhanh stream where
revetment works are to be implemented, and
residential area along the material transport road in
hamlets of Trung Tam, Ban Pa, Ban Phat, Roong

hamlet in Cao Ky commune;
Duration of impact: 18 months of construction
stage, especially in harvesting time (June and
December)
2.10 Impact on
existing
infrastructure of
the locality
Yes Minor Negative Temporar
y
During the construction process, the use of the inter-
hamlet road as transport route for building and waste
materials, overloaded trucks exceeding road capacity,
as well as the speed limit, will damage the roads, and
make the movement of local people, goods and
services difficult. Undisciplined drivers may even
damage social infrastructures along the transport
route if these are bumped by the trucks
This impact can be considered minor in view of: a)
Proper management of personnel which includes the
drivers of transport trucks can be able to prevent
damages to social infrastructures along the transport
route; b) the construction work site is on the stream
bank segment, where there is no social infrastructure
in place. Construction of revetment will therefore not
affect any local infrastructures; and c) the river
revetment actually contributes to the protection of the
adjacent farmlands owned by 50 households, a
kindergarten school, the inter-commune road, and
inter-hamlet road that are used as transport route,

The revetment, if properly installed, can help enhance
the natural beauty of the stream segment that had
been the subject of severe erosion and
sedimentation.
Stone steps provided along the revetment works, will
help local people to conveniently the stream waters
and take a bath, wash clothes and household
implements, and draw water for irrigating their farm
lands.

Positive/
Negative Long-term
Positive: The protection and stabilization of
farmlands, road and built-up areas along and near the
subproject area, may encourage increase productivity
among the local people. As a result, increase
investment may occur in the adjacent area that may
favour the change in land use from agriculture to
other uses (i.e residential and commercial). This
change in land use will provide new livelihood
opportunities for local people, possible increase in
their incomes and therefore improve the HH socio-
economic conditions.
Negative: The uncontrolled change in land use may
be a problem for the local government especially if
this is not anticipated in the long term development
master plan. Unplanned development, may mean the
logistical support needed by local people (i.e. potable
water supply, sewage treatment, garbage collection

VII.GRIEVANCE REDRESS MECHANISM
11. The CPMU has developed a grievance redress and resolution mechanism for environment to address grievances and complaints related to EMP implementation in a timely and satisfactory manner for the on-going similar projects (Figure 7).
12. Every attempt should be made to establish a rapport between the affected communities and the implementing agencies through frequent interactions and transparency thereby maximizing the resolution of grievances at commune level. A three-stage procedure for redress of grievances is proposed based on practice as follows:
(i) Stage 1: Complaints from affected people on any environmental damage caused by the project
implementation will be lodged verbally or in written form by the affected people (refer to
Appendix 8 for sample complaint form). The staff from commune/Commune Supervision Board
will assess the level of environmental damage and report to the PPMU within 15 days of the
complaint is received.
(ii) Stage 2: If no resolution can be reached or if no response is received from the liaison officer
within 15 days of registering the complaint, the affected people can take their complaint to the
District People Committee who will conduct a site investigation to assess the damage and
discuss with a contractor during the construction stage to determine and immediately take the
appropriate remedial measures within 30 days of the complaint is received.
(iii) Stage 3: If the affected people are not satisfied with the decision of District People Committee or
in the absence of any response, the affected people can appeal to the DONRE or Provincial
People’s Committee (PPC). The DONRE/PPC will provide a decision on the appeal within 45
days but not exceeding 60 days6, from the day it is received by the PPC. In this stage,
DONRE/PPC will enforce PPMU to take the strong corrective action to resolve the problems
either though enforcement of contractor’s duties under the signed contract or providing
necessary additional actions under its overall duties of project implementation.
13. A complaint or a case to the Court of Law may be done separately or independently from the Project level Grievance Redress mechanism filing process. Implementers of the mechanism should be guided by appropriate government decrees related to complaints such as: Law on Complaints No. 02/2011/QH13; Article 64 of Government Decree 84/2007/ND-CP; Clause 2, Article 40 of Decree 69/2009; and regulation on grievance at Government Decree 75/2012/ND-CP dated 20/11/2012.

VIII. CONCLUSIONS AND RECOMMENDATIONS
14. Subproject revetment to protect bank of Cau in Cho Moi district will be implemented by Bac Kan
PPMU of SRIDP in Cho Moi district, Bac Kan province.
15. Project environmental assessment was conducted and main potential environmental impacts of sub-
project in construction stage include:
(i) Loss of agricultural lands for use in the installation of revetment works;
(ii) Erosion or sedimentation caused by the construction activities (i.e. site clearing, soil excavation, back filing and droppings from transport of construction materials and waste;
(iii) Deterioration of air quality resulting from construction activities and transport of materials thru the inter-hamlet roads where the sparse residences are located;
(iv) Generation of solid waste and waste water from construction activities, and vehicle/equipment maintenance, as well as sewage from workers camp ;
(v) Risks of labour accident when carrying out the work on river in rainy season,
16. Main potential environmental impacts of sub-project in the operation stage include:
(i) The risks on the stability of revetments;
(ii) Uncontrolled change in land use adjacent to the sub-project area;
(iii) Positive effects of social and spirit of beneficiaries in the region.
17. A series of mitigation and monitoring measures have been developed for the sub-project, including
the following:
(i) To minimize the effects of air pollution, smoke, dust, vibration, noise, the contractor need to:
Restrict transporting distance causing effects to local communities; Implement dust reduction measures such
as spraying water on the inter-hamlet road surface during the dry season; Cover the cargo of trucks
transporting construction materials and wastes ; observe prescribed vehicle speed limits; and construction
vehicles and equipment are to be maintained in good working condition following their manufacturer’s
prescription.
(ii) To minimize the contamination of stream water that will affect the aquatic environment, the
contractor need to: a) store hazardous materials (i.e. fuel, oil, lubricants, and other petroleum products) in
secured, non-flood prone area, away from stream bed that has concrete floor and waterproof roofing; b)
avoid installing temporary construction facilities in flood-prone areas or near water sources; c) Ensure
vehicles and construction equipment are maintained in good working condition and promptly repair any
damage; d) avoid direct discharge of cleaning water from concrete mixers to stream water; e) provide
sanitary and potable water supply facilities in the workers camp following Ministry of Health standards, and f)
Waste water from worker’s camp to pass through the septic tanks prior to their discharge into the receiving
water or soil;
(iii) To minimize risks for health and safety of people as well as construction workers, the
contractor need to: a) Install informative signs (i.e. speed limit, no honking in residential areas, etc.) along
the inter-hamlet road used as material transport route; b) Inform the local leaders and communities living
near the sub-project area about construction plan and schedule (thru public meetings, loud speakers, posting
of information materials in the CPC bulletin board); c) provide personal safe equipment for workers and train
for them on how to use; d) designate Safety officers to help ensure safety at the construction areas; and e)
restrict access to construction areas of local community by installing fences and lighting facilities.
18. An Environmental Management Plan (EMP) had been developed containing the mitigation measures
identified, responsible persons/parties, location of areas on to which the plan will be implemented, as well as
40
the cost involved. The EMP will be made part and parcel of the construction bid documents, and the winning
contractor will have to prepare its site EMP acceptable to the subproject owner, which will be the basis for
payment on environmental works conducted. Similarly, an Environmental Monitoring Plan had been prepared
to indicate the activities to be monitored, parameters to be considered, responsible parties, timing and cost.
The Construction Supervision Consultant (CSC) will be responsible in monitoring the EMP implementation
and preparation of regular monitoring reports for submission to the PPMU.
19. Based on the findings about environmental assessment and EMP being stated in this document, the
following conclusions can be made:
The “River Cau protection embankment, Cho Moi district subproject” seeks to help ensure a stable
life for people in two communes of Thanh Mai and Cao Ky through prevention of stream bank erosion on 2
Cau river bank tributaries. A stable riverbank is expected to motivate the local farming community to improve
agriculture production, this would lead to increase in farm incomes and may help improve the socio-
economic conditions of the local people, and reduce poverty incidence in the area.
IEE report for the sub-project indicates no significant impacts on the environment, and confirms the
PPTA conclusion that the sub-project is among the other subprojects identified that have an environment
Category B classification. It is recommended that further environmental assessment on the subproject is not
needed. If is further recommended that the EMP crafted in this report be included in this subproject’s bidding
documents as part of the Terms of Reference, and winning contractors prepare a site EMP acceptable to the
PPMU, which will be the basis for payments related to environmental mitigation activities. Once approved,
the IEE will be the basis for implementing the next steps to ensure the project progress.
