1 INTRODUCTION. FRAMEWORK OF THIS REPORT
1.1 FRAMEWORK OF THE REPORT
Within the framework of the Environmental Control Plans proposed by the contractors and the
duties of the Consultant (PSC) in this matter contained in the Consulting Services Contract, the
environmental team of national specialists (NS) in charge of inspecting the environmental
conditions of the works for the new highway, have done weekly inspections along the sites
and surroundings of all the Packages which nowadays are all with construction activities,
checking the environmental measures applied by the constructors and detecting any impacts
that could be generated by the building works during the period of reference of this report, that
means, January, February and March 2012. The results were included in the environmental
weekly inspection reports (EWIR) and the monthly environmental reports for each package

April
In the site inspections, we still found that the dirt is being tracked onto public roads where the
construction sites intersect them. The Contractor also doesn’t clean these areas to keep them
in cleanliness and sanitary condition; this issue causes high spread of airborne dust in the hot
windy days.
At section Km 0+665 ~ Km 3+000, we also didn’t see the Contractor to spray water on surface
of embankment section in order to minimize the spread of dust in this area. The PSC had
many times warned the Contractor of this problem but till last site inspection on April 24 we still
didn’t perceive the Contractor to implement our requirement.
At section Km 19+650, the Contractor has already installed the fence of iron sheet surrounding
the construction area to minimize the spread of noise during carrying out construction activities
in this area.
We don’t find serious problems at other sections during the site inspections this month.
May
In the site inspection on May 03, we found that the Contractor still has not implemented
watering activity on surface of embankment sections such as sections Km 0+665 ~ Km 3+000,
Km 4+800 ~ Km 5+000 and at Interchange No. 3. The PSC has many times requested the
Contractor to wáter surface of embankment section to minize the spread of airborne dust
during hot windy day; however, the Contractor doesn’t implement our requirements. During the
remaining time of the month, it usually rained so there was almost no embankment work and
the dust was naturally minimized.
At Trung Kien Bridge and Dai Duong Bridge, during the site inspection on May 22, we found
that the workers had burned trash on sites. This activity is usually happened on sites despite
recommendation of the Engineer.
At other sections, we didn’t find serious problems during the site inspections this month.

By observations during this month we still perceived that the dirt is being tracked onto public
roads where the construction sites intersect them. The Contractor also doesn’t clean these
areas to keep them in cleanliness and sanitary condition; this issue causes high spread of
airborne dust in the hot windy days.
Along through way we also didn’t see the Contractor to carry out the watering activity on
surface of embankment sections to minimize the spread of dust during the hot windy day
despite many requirements of the Engineer. We issued the last warning to request the
Contractor to implement our requirements and if he still fails we will recommend the Employer
to deduct money.
At Batch Plant C, due to the Contractor still doesn’t comply with our requirements to install the
fence surrounding material stockpile area in order to limit the spread of airborne dust, therefore
the PSC has already deducted money.
At other section, there is no serious problem noted during the site inspections.

The status of tracking of dirt onto public road has not been mitigated. This matter caused
dirtiness and high spread of airborne dust, especially in hot windy days. At sections of
embankment, the Contractor also didn’t water the surface in dry days and this caused high
spread of dust, too. The PSC many times requested the Contractor to solve these problems
but up to now, there is no improvement recorded.
We didn’t see any improvement at Batch Plant C – Km 39+200, and in the site inspection on
May 21, together with expert of ADB, the Employer and the Contractor, we have taken public
consultation action in these areas and the local people disclosed that the level of dust is very
high during operation of this CBP. The PSC also stopped the work of this CBP until the
Contractor corrects the defect.
We also found that the trash was burned on site at Muong Dao Bridge. This activity is usually
happened on sites despite recommendation of the Engineer.
At other section, there is no serious problem noted during the site inspections.

During April, when inspection in site we has found that all dump trucks were not covered. Soil
from trucks was fallen a lot on existing roads (Km51+100, Km62, Km67…). Therefore, dust
was distributed much in the air. The Consultant requested Contractor must collect all fallen soil
on existing roads, spread water regularly on both existing roads and access roads along
package A3 base on site minutes dated April 17th, 2012 at Km66+300 to Km66+300 and letter

In May, after warning letter of Consultant from April, Contractor spread water for some existing
roads (Km68, Km75+400…). But when inspection in site we have found that on existing roads
(Km51+100, Km62, Km78+900…) dust was distributed much in the air so local people was
complain much about this problem.
Special after inspection tour of ADB mission on May 21st, 2012, the ADB’s specialist
interviewed some local people who lives next to construction site (Km78+900). These people
said that they can’t sleep because noise, vibration from construction activities during 24
hours/day. Beside, dust was full in the air on sunny and dry days, Contractor did not spread
water appropriately to minimize dust. Hence, ADB mission and Consultant requested
Contractor must build fence around construction site where next to residential area and limit
working time at night to minimize noise, vibration and avoid disturb local people’s life. On dry
days, Contractor must spread water appropriately to avoid dust.
The Consultant’s warning letter was ref. GET2-POS-A3-1285 dated June 1st, 2012 “Require to
overcome Environmental and Safety problems in package A3.

This month, through the inspection and supervision on site, the Consultant found that the
environment control and protection of the Contractor did not have much improvement. The
Contractor still failed to fully implement the measures to minimize the impacts on environment
in the process of construction and transportation of raw materials, such as:
- Most of the Contractor's trucks were not covered with canvas in the process of
construction and transportation of raw materials.
Loan 2391/2392 – VIE: GMS Kunming – Hai Phong Transport Corridor Noi Bai – Lao Cai Highway Project

- The Contractor did not perform the watering to minimize dust generated on site as well
as on the materials transportation roads such as at Km111, Km112, Km123, Km145, ...
- At the factories of the Contractor such as the RC Pipe Culvert Factory No. 1 (Km117),
RC Pipe Culvert Factory No. 2 (Km132), concrete batching plant No. 1 (Km123),
concrete batching plant No. 2 (Km132), the Contractor did not apply any measures to
minimize dust during operation.
This has caused adverse impacts on the regional air quality. The Consultant has reminded the
Contractor on these outstanding issues (mentioned in Ref. GET3-KEANGNAM-12-A5-361
dated April 24, 2012). In addition, the Consultant has also required the Contractor to apply
adequate measures to minimize dust during construction and transportation of materials to
prevent adverse impacts on the regional air environment.
In the weekly site inspections, the Consultant has also frequently requested the Contractor to
fully comply with the Method Statement as well as the Environment control and protection plan
during construction to ensure the air quality.
This month, the Contractor carried out air quality observation on 15th April, 2012 in the
construction locations of the Contractor which are close to residential areas; the observation

Through the inspection and supervision on site, the Consultant found that there are still some
outstanding issues in the environment management of the Contractor during construction and
transportation of materials. This has affected the regional air environment, namely:
- The Contractor did not conduct water spraying to minimize dust generated during
construction and transportation of materials in some areas such as: Km111, Km117,
Km119, Km123, Km145, Km148...
- During the material transportation of the Contractor, most trucks were not covered with
canvas.
- The Contractor did not apply any measure to minimize dust generated in their factories,
such as the RC Pipe culvert factory No1 (Km117), RC Pipe culvert factory No 2
(Km132), concrete batching plant No 1 (Km123), concrete batching plant No 2
(Km132)...
To ensure the regional air environment, the Consultant has reminded the Contractor on these
outstanding issues (Ref. GET3-KEANGNAM-12-A5-438 dated May 16, 2012 and GET3-

- The water spraying to minimize dust generated during construction and materials
transportation of the Contractor was not conducted on sites and on transportation roads
such as: Km111, Km113, Km117, Km130, Km145, Km148...
- Measures to minimize dust generated in the plants of the Contractor have not yet been
applied fully such as in the concrete batching plant No. 1 (Km123), concrete batching
plant No. 2 (Km132)...
Loan 2391/2392 – VIE: GMS Kunming – Hai Phong Transport Corridor Noi Bai – Lao Cai Highway Project

- In the process of construction and materials transportation, soil dropped on the public
roads such as at Km123+680, Km126, Km145... this created dust when the vehicles
drove through this area, especially in hot days.
The Consultant has warned the Contractor on the outstanding issues in Ref. GET3-
KEANGNAM-12-A5-565 dated June 27, 2012. In addition, the Consultant has also required the
Contractor to quickly take steps to address them and ensure the regional air quality during the
construction process.

This month, through the inspection and supervision on site, the Consultant found that the
Contractor has continued to perform watering to minimize dust on the site at some locations
such as: Km157, Km184, Km186, Km187... Besides, in the month there were some rainy days,
so the amount of dust generated during construction process and transportation of raw
materials was reduced significantly.
However, in this month, there are still some outstanding issues as follows:
- Most of the Contractor's trucks were not carefully covered with canvas in the
transporting process of raw materials.
- At the construction locations Km151-Km152, Km174, many soil dropped on public
roads during transportation of rzaw materials of the Contractor; this has generated dust
in the hot days.
- At some stations such as Km174, Km176, Km165, Km183..., the watering work on the
public roads and on site has still not been carried out regularly. Therefore, on some hot
and windy days, the vehicles driving through these locations caused dust, which
affected the regional air quality.
- In the factories of the Contractor such as batching plant Km163, batching plant Km165,
batching plant Km180, measures for minimizing dust during production process were
not fully applied by the Contractor.
The Consultant has reminded the Contractor on these outstanding issues (Ref. -DOOSAN-12-

Through the inspection and supervision on site this month, the Consultant found that
Contractor has still conducted water spraying to minimize dust at some construction locations
and transportation road of raw materials such as: Km157, Km158, Km165, Km184, Km185,
Km187... Besides, the amount of dust generated during construction and transportation of raw
materials has also been substantially reduced due to the number of rainy days in this month.
However, there are still some outstanding issues as follows:
- The Contractor's trucks were not covered with canvas in the process of transporting
raw materials.
- Soil was dropped on the public roads during construction and transportation such as at
Km151, Km159, Km174, Km157... this is the cause of the situation of dust when
vehicles drove on these public roads, especially in hot and windy day.
- The process of construction and materials transportation of the Contractor are
responsible for the generation of dust in areas such as: Km151, Km156+300,
Km156+475, Km161... The Contractor has carried out water spraying in these areas to
minimize dust, but the work was not done regularly and the frequency of water spraying
was less, so the amount of dust was generated in the process of raw materials
transporting, especially on sunny days.
- The Contractor has not yet fully applied measures to minimize dust generated during
operation of the factories such as the concrete batching plant Km163, Km165 and
Km180.
To ensure environment of the Project, the Consultant has reminded the Contractor on these
outstanding issues. Also, the Consultant has required the Contractor to apply measures to
minimize dust during construction, transportation (Ref. DOOSAN GET3-DOOSAN-12-A6-484
dated May 14, 2012) and during the operation of the Contractor’s batching plant (Ref. GET3-

Rainy season has started in this month, so there were many rainy days in the month, which
significantly reduced the amount of dust generated during construction and transportation of
raw materials. Besides, water spraying to ensure dust minority has being deployed in some
areas such as: Km157, Km156, Km165, Km176, Km185, Km184, etc.
However, through our inspection and supervision on site, we found that there were still some
outstanding issues which influence the air quality in the area as follow:
- In areas of Km151, Km165, Km155, Km174, ... there was a lot of soil spillage on public
roads during transportation of materials; besides, on a rainy day, the land from the
Project area flooded the public roads in the area of Km159 +690 , Km157+090,
Km155+220, Km151+200, etc., which was the cause of the condition of dust from traffic
vehicles in the area, especially in hot and windy day.
- Currently, most of the Contractor's truck did not make full use of canvas in the process
of transporting raw materials.
- In some areas such as: Km176, Km174, Km187, etc., although the Contractor carried
out water injection in these areas, the frequency of water spraying was not enough; so
it still underlied the condition of dust when a number of vehicles ran through this area,
especially on hot days, which affected the air quality in the region.
- In areas of concrete batching such as Km163, Km165, Km180, etc. measures to
minimize dust during operation were not fully applied.
The Consultant reminded the Contractor on the outstanding issues and we also required the
Contractor to implement measures to minimize dust generated during construction,
transportation of materials, in order to ensure air quality in the area (mentioned in Ref. GET3-
DOOSAN-12-A6-546 threads May 31, 2012 and GET3-DOOSAN-12-A6-569 threads June 9,

The similar status was also recorded at Underpass NH2, the direct discharge of untreated
wastewater containing sand and mud into existing irrigation canal is still going on. The PSC
has strongly warned the Contractor and if he still fails to meet our requirements we will
consider applying the measure of money deduction. The next site inspection will be held on
May 03, 2012 to check the implementation of the Contractor.
At other sections, we did not see the serious problem happening during the site inspections.

In the site inspections this month, we still found that at Tan Loi Bridge the Contractor has not
taken any action to improve the status here. Due to the heavy rains, Piers 2 and 3 construction
site is now under the water.
At Underpass NH2 the Contractor constructed a sediment basin to catch sediment from
wastewater before discharge of it offsite. However, the capacity of this device is not enough
and the PSC has requested the Contractor to construct one more to ensure that the sediment
is not spilled-over existing drainage. And this time is in harvest and straw is available, so traw
bales were recommended as a sediment check dam to be installed at outlet of untreated
wastewater discharge area to remove sediment from wastewater.
At other sections, we did not see the serious problem happening during the site inspections.

In the site inspections we found that there is no improvement at Ben Tre Bridge; however, the
Contractor also does not let the problem worse. The procedures of payment progress
suspension of all items of this work is still going on until the Contractor corrects the defects
completely.
At Muong Dao and Ban Gao Bridge, we perceived that the Contractor still didn’t take any
action to correct the issues and he even discharged the untreated wastewater that contains
sand and mud directly into river at Ben Gao Bridge. The PSC has many times requested the
Contractor to solve these problems as well as instructed him how to treat wastewater before
discharge of it but there was no improvement recorded. For Ben Gao Bridge, we have already
recommended the Employer to deduct money due to the Contractor didn’t solve the problems
and let them worsened. We also still close the procedures of payment progress of all items of
these works until the Contractor implements our requirements.
On Mar 28, we found that the Contractor had discharged the bentonite slurry into river at Pier 7
of Lo River Bridge. The PSC has strongly warned the Contractor and requested him to stop
this activity. However, in the site inspection on April 11, we again found that he already
disposed all the bentonite slurry, sand and mud – by product due to bentonite slurry recycle
into river at the place as before. The PSC has requested the Contractor to remove all the
unsuitable material that remains on riverside concomitant with persons in charge discipline.
At Batch Plant 2 of Lo River Bridge, the improvement is very behindhand. The settling pond is
very unsettled and it seems to be broken easily in heavy rain. There is also no drainage on
surface to handle the surfaced runoff so the surfaced wastewater could flow directly into river
in the rain.
At other places, we didn’t detect any serious problem happening during the site inspections

to ensure its capacity. On May 22, we found that the Contractor has implemented our
requirement.
On May 21, in the site inspection we found that the settling ponds of CBPs 1 and 2 of Lo River
Bridge were full already. To prevent leaking of untreated cement-laden wastewater into
adjacent water resources the PSC has requested the Contractor to immediately remove the
sediment in settling ponds to ensure their capacity or install new ones to replace. We will

At P3 Red river bridge, the Contractor set up a big hole to collect all waste water contain
cement from batching plant here. But it’s too small compare with waste water volume, and it
had no canal to lead waste water from batching plant to sediment control hole. So we
requested Contractor must extend this hole to satisfy waste water volume of this plant. This
action will ensure that waste water contain cement not overflow into Red river.
At P7 Red river bridge, Contractor did not dig sediment control hole to collect waste water from
batching plant although Consultant requested many times.
In inspection tour of ADB mission, they requested Contractor must set up sediment control
hole on each Cement batching plant. Deadline is June 8th, 2012, if Contractor still delay

During inspection tour of ADB mission, Consultant showed them many serious impacts on
water quality in package A4 which were not resolved by Contractor in long time as:
- Bentonite was poured directly into Ngoi Gianh river. Beside, pebble and soil which was
washout from access road filled more than haft of this river bed. It impacted to water
quality of this river.
- In addition, at Ngoi Lao and Ngoi Van river, pebble and soil which was washout from
construction activities. Although Contractor have some solution in Ngoi Lao to avoid
bentonite overflow into river as: set up a small hole to collect waste bentonite but it was
not efficient. Now they finish drilling bore pile in this riverside but waste bentonite was
not resolved absolutely. It occupied a part of river bed. And the other riverside of Ngoi
Lao, soil and stone was fallen much into this river.
ADB mission requested Contractor must dredge all waste mud or bentonite which was
occupying a part of riverbeds immediately they finish construction works (drilling bore pile,
concrete foundation of pier…). Contractor promised they will resolve it before June 15th, 2012.
Therefore, Consultant we will closely recheck in site on next month.
Consultant’s warning letter is ref.GET2-KEA-A4-638 dated May 4th, 2012 and GET2-KEA-A4-

This month, through the inspection and supervision on site, the Consultant found that there are
some outstanding issues as follows:
- The bentonite was not strictly controlled by the Contractor at some construction
locations such as Ngoi Gua bridge, Ngoi Rao bridge, Ngoi Thia bridge... This has led to
the situation of bentonite running down to the stream areas.
- The fuel control of the Contractor has not been done well at the fuel stations such as
Km136, Km112, Km145... The Consultant has found traces of oil leaked on the ground.
- At most of the workers’ camps of the Contractor, appropriate wastewater treatment
systems have not been built such as at Km120, Km136... The wastewater from the
workers’ camps was discharged directly into the environment.
This situation has affected the region's water quality. The Consultant has reminded the
Contractor on these outstanding issues in Ref. GET3-KEANGNAM-12-A5-361 dated April 24,
2012. Beside, the Consultant has also required the Contractor to apply measures to address
thoroughly these outstanding issues to ensure the region's water quality and prevent negative
impacts on the Project’s environment.
This month, the Contractor carried out observation of water quality in some areas; the
observation results are shown in the table 4.15.

Through the inspection and supervision on site this month, the Consultant found that the
Environment control and protection of the Contractor has not much been improved over the
previous month. The Contractor has not fully complied with the requirements of the Consultant
and of the Project, which has led to a number of outstanding issues as follows:
- The fuel control of the Contractor has not been implemented well at the fuel stations in
areas such as Ngoi Gua bridge, Ngoi Rao bridge, Ngoi Thia bridge... In the site
inspections, the Consultant found traces of oil leaked on the ground.
- The contractor did not comply with the requiremennts and the instructions of the
Consultant about the bentonite control in the construction process at the construction
locations such as Ngoi Gua bridge, Ngoi Rao bridge, Van Phu bridge... which has led
to bentonite running down to the stream areas.
- Suitable waste water treatment systems were not built by the Contractor in the workers’
camps such as Km136, Km145, Km120... As the result, the waste water from the
camps area was discharged directly into the environment.
- The Contractor has not built waste water treatment system at some factories such as
RC Pipe Culvert Factory No. 1, RC Pipe Culvert Factory No. 2, RC Pipe Culvert Factory
No. 3...
- At station Km123+740, the Contractor poured soil into the lake Y Kan, which has
affected the water quality of the lake.

This month, through the inspection and supervision on site, the Consultant found that the
construction activities of the Contractor have not created serious impacts on the regional water
quality. Most of the Contractor's construction works did not produce hazardous substances to
the aquatic environment.
However, in this month, there are still some outstanding issues as follows:
- The fuel management of the Contractor has not much been improved this month, such
as at Km186, Km173, Km155... there were still many oil barrels located directly on the
ground, and they did not have any equipment to prevent oil leakage, which could lead
to oil leakage. Then, when there was rain, the rain brought oil to the region's water
source, affecting the water quality.
- The factories of the Contractor such as batching plant Km165, batching plant Km163,
batching plant Km180, batching plant Km1184. The waste water treatment systems of
the plants were still not under construction.
- At the workers camps of the Contractor, proper waste water treatment systems were
not built; therefore, the waste water from the camps area was discharged directly into
the surrounding environment.

The Consultant has reminded the Contractor about these outstanding issues (mentioned in
Ref. GET3-DOOSAN-12-A6-387 dated 19 April, 2012, GET3-DOOSAN-12-A6-435 dated 27
April, 2012). In addition, the Consultant has also required the Contractor to quickly apply
appropriate measures to address them thoroughly to ensure the region's water quality.
In the weekly site inspections, the Consultant has also frequently reminded the Contractor to
comply with the Method Statement as well as the Environmental Control and Protection Plan of
the Project to prevent adverse impacts on the regional nature water from the construction
activities of Contractor.
May
Through the inspection and supervision on site this month, the Consultant found that the
region's water quality has not been seriously affected by the construction activities of the
Contractor. Most of them were conducted within the project’s limit and have not made serious
impacts to the water quality. In addition, the Contractor also has built the trap basins in the
batching plant to deposit solids before discharging water from the plant area into the
surrounding environment. However, there are still some outstanding issues as follows:
- In the south portal of tunnel areas, the Contractor has still not built waste waster
treatment system as in the requirements in the Method Statement, and the lack of
attention in the use of temporary waste water treatment system. This has led to the
situation of waste water from the tunnel construction area which was not thoroughly
treated before discharged into the surrounding environment. The Consultant has
warned the Contractor about this in Ref. GET3-DOOSAN-12-A6-457 dated May 4,
2012.
- The fuel management of the Contractor has not yet been done well at some fuel
stations such as: Km186+200, Km155+300... in these areas, the Consultant has found
that the fuel tanks were placed directly on the ground and they did not have any
equipment to prevent fuel leakage. The Consultant has provided specific instruction for
this issue in Ref. GET3-DOOSAN-12-A6-300.
- A number of workers’ camps of the Contractor such as Km184+057, Km182+160,
Km167+879, Km163+126... the Contractor has not built waste water treatment system
suitable for the workers’ camps, so the waste water from the camps area was
discharged directly into the surrounding environment. The Consultant has requested

the Contractor to resolve the outstanding issues in Ref. GET3-DOOSAN-12-A6-491
May 15, 2012.
Also, in the weekly site inspections, the Consultant has frequently reminded the Contractor to
comply with the Method Statement and the Environment Control and Protection Plan of the
Project to prevent negative effects on the region's water quality from the contractor’s
construction activities.
June
This month, through the inspection and supervision on site, Consultant found that the
construction activities of the Contractor have not caused serious impacts to soil quality in the
region. During this period, the major construction activities of the Contractor remains
earthworks (excavation, embankment...) and built the piers of the bridge, etc., so there has
been no generated substances that cause serious impacts to water quality.
In addition, in concrete batching areas such as Km180, Km165, Km184,etc, the Contractor has
also built trap basins to recover waste water, as deposition of solids in the water before
discharge into surrounding environment.
However, through our supervision and inspection on site, we found that there were still some
outstanding issues as follows:
- The Contractor has started the tunnel construction work since a long time, but waste
water treatment system mentioned in the Application methods has not been under
construction yet.
- The fuel management of the Contractor has improved, however, there were still fuel
tanks placed directly on the ground as in Km186 +200, +300 Km155, Km178 +200, etc.
- Waste water treatment system at workers’ camps in the area of Km184+057,
Km182+160, Km163+126, etc., has not been built properly, waste water from the camp
area has been discharged directly into the environment.
To ensure the Project's environment, the Consultant reminded the Contractor on these
outstanding issues, at the same time, we also required the Contractor to apply measures to
resolve the outstanding issues in order to ensure environment quality of the Project in general

In the site inspections, we again detected the sloppy status in oil usage at Trung Kien Bridge,
Tan Loi Bridge, Tam Long – Thien Ke Bridge, Km 4+700, the oil barrels were put on ground in
disorder and lying on their side. The PSC had strongly warned the Contractor of this issue and
requested him to comply with regulations in oil usage and management. In the site inspections,
on April 04, we found that there was improvement at Km 4+700 and Tam Long – Thien Ke
Bridge but Trung Kien Bridge and Tan Loi Bridge. At Trung Kien Bridge and Tan Loi Bridge,
the Contractor still let this issue happen that caused leak of oil on ground. In the next site
inspections we also did not see any improvement in these areas.
At Underpass NH2 construction site, the direct discharge of untreated wastewater that
contains sand and mud into existing irrigation canal is still going on. The Contractor does not
implement the requirements of Engineer to mobilize dewatering tank or gravity bag filter to
remove sediment from wastewater before discharge of it. The PSC already issued a warning
letter to request the Contractor to implement our requirements and if he still fails to meet
requirement of us, we will consider applying the measure of money deduction.
The riverside landslide risk is still high at Tan Loi Bridge, especially in the rainy season due to
the Contractor doesn’t apply any countermeasure in this area. Similar issue was found at Xuan
Phuong Bridge. The PSC has many times requested the Contractor to solve this issue to
protect riversides but up to now he doesn’t take any action to implement our requirements.
At section Km 4+700 ~ Km 4+800, almost the unsuitable material was removed.

inspection we still realize that this problem is not solved we will consider deducting money.
The Contractor already constructed a sediment basin to catch sediment from waterwater at
Underpass NH2 construction site. However, this sediment basin is not enough capacity so the
Engineer has requested the Contractor to supplement another beside to ensure that almost
sediment will be remove from wastewater before it spills-over existing drainage. The straw
bales installation at outlet of wastewater discharge area were also recommended as a effective
measure to remove sand and mud from wastewater.
By observations during this month, we realized that there is no improvement at Tan Loi Bridge
and Xuan Phuong Bridge. The Contractor still has not applied any riverside protection
measures to prevent landslide happening on riversides.

This month, the major items of the package’s construction works are soil work and some other
activities such as bridges, sewers, under pass box culvert... and the majority of them did not
make substances that cause serious impacts to soil quality in the region.
However, because the Contractor did not fully comply with the requirements of the Project as
well as the instructions of the Consultant, some outstanding issues has occurred as follows:
- The performance of the Contractor in managing fuel was still poor; this has led to oil
leakage at some fuel stations of the Contractor such as Km136, Ngoi Thia bridge, ...
This has affected the soil quality of the area.
- Bentonite has not been controlled tightly by the Contractor during the construction
process in areas such as Ngoi Rao brigde, Ngoi Gua bridge... This has led to the
bentonite surface runoff, which affected soil quality of the area.
- At some stations such as Km118 - Km119, Km116 - Km117, the soil from the Project’s
area flooded the production areas of local people (agricultural land, forest land,
aquaculture land). In the rain, this has affected the soil quality of the local people.
The Consultant has requested the Contractor to quickly apply effective measures to address
thoroughly these outstanding issues to ensure the region's soil quality. Besides, in the weekly
site inspections, the Consultant has also frequently required the Contractor to comply with the

Through the inspection and supervision this month, the Consultant found some outstanding
issues as follows:
- Because the Contractor did not fully comply with the instructions and requirements of
the Consultant. On some days of heavy rain, soil from the Project’s area flooded the
production areas of local people (agricultural land, forestry land, aquaculture land); this
has affected the regional soil quality such as Km116 - Km117, Km117 - Km118,
Km119, Km126, Km127...
- The Contractor has not fully applied necessary measures to control the bentonite
during the construction process. This has led to the phenomenon of bentonite surface
runoff in areas such as Ngoi Rao bridge, Ngoi Thia bridge, Ngoi Gua bridge...
- This month, the contractor's fuel management has had no improvement. At the fuel
station such as Ngoi Gua bridge, Ngoi Rao bridge, Van Phu bridge... the Consultant
has found traces of oil leaked on the ground.
- At some construction locations such as Km111, Km123, Km148..., the Contractor has
gathered unsuitable soil in areas which have not yet been approved by Consultant.
To ensure the regional soil quality, the Consultant has requested the contractor to quickly
apply effective measures to resolve these outstanding issues (Ref. GET3-KEANGNAM-12-A5-
490 dated 31 May 2012). Besides, in the weekly site inspections, the Consultant has also
frequently required the Contractor to comply with the Method Statement as well as the

negative impacts of the Project on the environment in general and on the regional soil quality
in particular.

However, because the environment control and protection of the Contractor was not done well,
a number of outstanding issues has raised as follows:
- At stations Km116-Km117, Km117-Km118, Km119, Km126, Km127... the Contractor
did not fully comply with the instructions of the Consultant as well as the requirements
of the Project, so on a number of rainy days, soil from the Project’s area has flooded
the production areas of local people (agricultural land, forest land, aquaculture land).
This has affected the region's soil quality. However, so far, the Contractor have not yet
fully solved this problem (Ref. GET3-KEANGNAM-12-A5-594 dated June 29, 2012).
- Bentonite was not tightly controlled during the construction process in areas such as
bridges Van Phu, Ngoi Rao, Ngoi Gua, Ngoi Thia,... this has led to the bentonite
surface runoff, affecting the soil quality.
- The fuel management of the Contractor was not done well in areas such as the fuel
stations Ngoi Thia bridge, Ngoi Gua bridge, Van Phu bridge, Ngoi Rao bridge, Ngoi Lau
bridge... The Consultant found that the fuel tanks were located directly on the ground
without any device to prevent fuel leakage, which may cause traces of leaked fuel on
the ground, affecting the soil quality.
To ensure the Project's environment quality in general and the soil quality in particular, the
Consultant has asked the Contractor to solve these outstanding issues. Besides, in the weekly

have not been equipped with adequate devices to prevent oil leakage. Besides, there is
still the phenomenon of the fuel tanks put directly on the ground; this could lead to oil
leakage, affecting the regional soil quality.
- Erosion has occurred in the embankment area of the Contractor on some rainy days of
the month, and this led to the phenomenon of soil from the project’s area flooded the
production area of the local people, afftecting the soil quality in production land such as
Km156, Km176, Km172...
The Consultant has requested the Contractor to apply effective measures to thoroughly
overcome the outstanding issues. Besides, in the site inspections, the Consultant has
frequently required the Contractor to comply with the Method Statement and the Environment
Control and Protection Plan during construction to prevent the negative effects from the
project’s construction activities on the region's soil quality.
June
Through the inspection and supervision in this month, we found that the activities of
construction have not caused serious impacts to soil quality of the area, however, there are still
some outstanding problems as follows:
Loan 2391/2392 – VIE: GMS Kunming – Hai Phong Transport Corridor Noi Bai – Lao Cai Highway Project

- The fuel management of the Contractor has been improved, however, there were still
fuel tanks placed directly on the ground without any device to prevent oil leakage as in
Km186 +200, Km186+720, Km178 +200, Km155+300, Dai Viet bridge, etc.
- In the days of heavy rain, in areas under drainage construction as Km168, Km178, etc.,
the drainage pipes have not been completely constructed, which hindered the water
flow through these areas, led to the flooding in upstream drainage and erosion in the
drainage downstream, affecting soil quality production of local people.
The Consultant asked the Contractor to quickly apply the measures to resolve these
outstanding issues (mentioned in Ref. GET3-Doosan-12-A6-566 and GET3-Doosan-12-A6-
546). .
Because the rainy season began in early A6 bidding package, the Consultant has asked the
Contractor to apply measures to ensure the environment during the rainy season through
GET3- DOOSAN-12-A6-650 dated 29 June, 2012 .
This month, the Contractor continued to implement grass planting in the area of embankment
slope and cutting slope to limit the erosion, especially during the upcoming rainy season.

In coming months, the Consultant will regularly test noise level in the sensitive areas and
residential areas with the sound meter SC-2c to timely detect the areas with the noise levels
over permitted TCVN in order to advise the Contractor to implement the noise minimization
measures that are appropriate in that area.

This month, through the inspection and supervision on site, Consultant found that the activities
of construction have not caused serious impact on noise and vibration to the surrounding area
of Provision Project.
However, there are still some outstanding issues as follows:
- Due to the construction of some bridges on the route, the pouring of concrete for bridge
construction items was implemented on night time, the vehicles which transported
Loan 2391/2392 – VIE: GMS Kunming – Hai Phong Transport Corridor Noi Bai – Lao Cai Highway Project

construction materials caused noise to the residential sector at Km165, Km157, etc.
However, these effects were local only and did not last long, Consultant reminded the
Contractor on this issue, and also required the Contractor to comply with construction
measures at night time to minimize the effects on noise and vibration to the
surrounding areas.
- In the mixing region which was close to residential areas as Km180, Km165, Km163, ...
the Contractor has not fully applied measures to minimize noise during manufacturing
operations. The Consultant reminded the Contractors on this issue. In the weekly on-
site inspections, the Consultant also guided the Contractor for the construction of walls
to minimize noise in the mixing area.
In June 2012, the Consultant conducted measuring the noise level in some areas with the
sound meter SC-2c.

During this period, the major construction items of the Contractor were still earthworks such as
site clearing, excavation, backfill... Therefore, they have not raised serious effects on the
regional environment. Besides, the construction activities of the Contractor were within the

control of Contractor has not much been improved. At many construction locations, the safety
control of the Contractor has not been done well:
- Many workers do not use fully Personal Protection Equipment (helmet, safety shoes,
etc.) when they work on the site such as: RCPC factory No.1, RCPC factory No.2;
Batching Plant No.3, Ngoi Gua bridge; Ngoi Rao bridge; Van Phu bridge, etc.
- Safety fences and safety signboards: these safety elements have not been installed
fully at many construction sites (example such as: construction site of Ngoi Gua, QL37,
Van Phu bridges, etc.; access roads Km113, Km138, Km117-Km119, etc; other
construction sites such as Irrigation box culvert Km118+202, Underpass box culvert
Km118+224, Drainage pipe culvert Km118+060, Km118+860, etc; construction sites
intersecting with public roads Km123+860, Km145+220, Km148, etc) or these safety
elements are not meeting the Project’s requirements, not ensuring safety ( Ngoi Rao
bridge, Ngoi Thia bridge, etc.).
- Safety of public: at many construction sites, local peoples entering into construction
sites without any the Contractor’s control and supervision, this situation may cause
unwanted accidents inside project areas at any time.
- First aid base: this First aid base still has not been supplied by the Contractor as the
project’s requirements.
- Fire extinguishers: the Contractor has not provided fully these equipments at workers’
camps (such as: Km120+460, Ngoi Gua bridge, etc) or fuel store areas (such as Ngoi
Rao bridge, Ngoi Thia bridge, Ngoi Gua bridge, etc).
- The Contractor’s fuel control is not well performing (regarding to the Engineer’s letter
No.GET3-KEANGNAM-12-A5-215 dated 21st Mar, 2012).
For these reasons, the Engineer issue this official warning to Safety Manager of the
Contractor, who did not fulfill his responsibility in his position
The Engineer also reminded the Contractor that safety is a very important part in the process
of project implementation. Hence, the Contractor’s safety manager must take strong and
proper actions to make the site safe and prevent unsafe working practices or other
infringements on the safety plant or the statutory regulations.

7 GRIEVANCE INTAKES. PUBLIC CONSULTATION
As Annex 2 we include some grievance intakes (public consultations), written in a form sheet by Consultant, about complaints which were expressed by local people affected by the construction works, to the environmental or social impact specialists.
As Annex 3 there is included the information about the instructions given to contractors in order to establish a “complaints communication system” for local people. Although in some packages it was already implemented, the Engineer did not receive any complaint yet.
It’s supposed that these are not the only existing complaints, but the only ones received or collected by Consultant.

On April 25 2012, the environmental specialist in site team 1 was informed by Engineer’s
staff (inspector) on site that an accident happened in Lo River Bridge, by date April 22
2012.
When this information was received, the specialist went immediately to site in order to get
the information about that accident. The inspector from Consultant explained him that the
accident happened when a worker fell from the access way to a pier, which is located over
the flow, into the water and died by drowning.
In order to increase the information, the specialist investigated among local people around
Lo River Bridge and he was informed by them that, in fact, one person died into the water
on the last Sunday morning.
Whit this information, the Engineer requested the Contractor to investigate the facts, to
extend the information and to submit to Consultant a report about these facts. The report
from Contractor is included in this report as Annex 1.
In this report, more details are given about the accident:
� Number of workers involved: one.
� Data of the worker: name, age, address.
� Time of the events: 6.00 am, out of working time.

� Weather and other external circumstances: because of hard rains those days,
the level of the flow had increased significantly. Also, the ships that sail
continuously along the river generated strong waves that crashed against the
floating path.
� Personal circumstance: the worker was not wearing the obligatory life-vest at the
moment he was crossing it.
� After falling down into the water, other workers in the surroundings noticed about
it and tried to rescue him and carried out first-aid treatment but finally,
unfortunately, the accident had fatal consequences.
CONSULTANT’S CONSIDERATIONS
Once described the facts, Consultant has to include its considerations and opinions about
the events, reasons, circumstances and explanations given by Contractor. They are the
following:
� The Engineer’s environmental specialists (site team 1 and core team) had
inspected this floating access path all weeks. As it is mentioned in all the reports,
our consideration was that it was strongly installed and with a good maintenance
to be considered no dangerous.
The path has, in fact, handrails installed in both sides, as well as several safety
floats distributed along the handrails (see picture 2).
Also, it must be mentioned that the height of the path is so short from the surface
of the water in order to avoid any additional risk in case of falling (see picture 1).
� The Engineer’s environmental specialists (site team 1 and core team) had
inspected every week the general safety measures implemented on site,
checking and proving that Contractor provided to all workers with personal
protective equipment (PPE), which they use as a custom and following
instructions from Consultant and Contractor, on site (see picture 1).
� The piers are provided with safety scaffoldings, made with metal and well fixed
all the bars, and surrounded in the four sides by a net to avoid falls from the

scaffolding. On the top of the piers, a fence or a net surrounds the working
surface to avoid falls (see picture 3).
� The ladders, located in other piers or other sides to scaffoldings, are metal ones,
fixed to metal girders and are provided with a handrail (see picture 4).
� Contractor has carried out training sessions, periodically since the beginning of
the works, about safety measures to be taken by the workers and about the use
of the PPEs: obligatory, need and how to use it (see picture 5).

CONCLUSIONS
The conclusion for the events above mentioned, under Consultant’s consideration, are the
following:
1º Necessary safety measures to guarantee the safety conditions for workers on
site were applied in Lo River Bridge site.
2º A unexpected action from the worker, with a clear lack of precaution, happened.
3º Fortuitous adverse circumstances joined at that moment
According to these considerations, it can be asserted that the accident happened that day in Lo River Bridge was a completely unlucky accident, despite all the reasonable safety measures were implemented on site.
II – SAFETY INCIDENT REPORTING SYSTEM
According to the instructions from ADB, included in the Memorandum of Understanding
(MoU) of the last ADB Mission carried out in May 2012, the Engineer has informed to all
contractors about the decisions taken during that mission, related with the incidents
reporting system which has to be implemented in all packages.
In order to be informed in the first 24 hours after an incident related with safety happens in
site, the International Environmental Specialist has prepared a Incident Reporting Form,
which has been sent to all contractors, as well as the instructions to be followed in those
cases. This report form is included in this document as Annex 2.
III – COMPLAINTS INFORMATION AND RECEPTION SYSTEM
According to the instructions from ADB, included in the Memorandum of Understanding
(MoU) of the last ADB Mission carried out in May 2012, the Engineer has informed to all
contractors about the decisions taken during that mission, related with the complaints
information and reception system which has to be implemented in all packages. The
instructions given were the following:
Loan 2391/2392 – VIE: GMS Kunming – Hai Phong Transport Corridor Noi Bai – Lao Cai Highway Project

- Contractors will appoint a responsible to receive all the complaints from the local
people around sites, who could be affected by the works.
- In no more than 24 hours, the complaints must be submitted to EPMU and to
GETINSA.
- The way to inform local people about the system to submit the complaints to
contractor will be by adding in all temporary signs existing on site (or in new ones
if no temporary signs in any location near houses), a new line with the name and
telephone number of the appointed responsible, detailing that he/she is the
responsible to receive complaints. Also local and district authorities will be
informed about this system to complain.
- This system must be implemented before 30th June 2012.
- As Consultant must check the compliance in order to include the monitoring of
this issue in the monthly report for June and in the corresponding quarterly
report, Engineer established a deadline for the compliance, before 23rd June
2012.
During the last week of June, site team specialists were checking the real implementation of
this measure, with the following results:
A1 A2 A3 A4 A5 A6 A7 A8
Compliance Yes Yes In phase1
No No No No No
1: Contractor in package A3 is implementing the system. Consultant has received in the
last days of June 2012 a document in which POSCO explains the procedure to
receive and communicate claims, which is basically the procedure they were
instructed to apply.
As it can be proved in the table, the system has been fully implemented only in packages
A1 and A2 (POSCO Contractor) and it’s in phase of implementing in package A3 (POSCO
Contractor).
