3. CHANGES IN PROJECT SCOPE

There is no change in original scope of work given in IEE and Environmental Impact Assessment (EIA)

report. However as discussed with EPMU-BLLT they want some additional scope of work for

Environmental supervision. The additional scope work consists of following items.

The terrestrial wildlife and biodiversity study in Package-7 is desired by the EPMU-BLLT. There

are mangrove forests in package-7 which will be directly and indirectly affected due to

construction of expressway. The EPMU-BLLT wants to undertake the study on impacts of

construction activities on Mangrove Forest and animals living in this forest. The study is beyond

the scope of work given in TOR. The CSC will employ one subcontractor to carry out this study.

The EPMU-BLLT has desired the study of aquatic ecology of the Package-7. The

subcontractor will be employed by the CSC for this additional study. Also there would be

additional cost for this study as this study is beyond the scope of work of TOR.

Page 11

The other additional study desired by the EPMU-BLLT is to study the future air and noise pollution level due to increase in traffic or vehicle volume on Expressway. The air and noise modeling will be carried out by subcontractor to predict the future air and noise levels on expressway. INCORPORATION OF ENVIRONMENTAL REQUIREMENTS INTO PROJECT CONTRACTUAL ARRANGEMENTS

All the terms of the UEMP must be in contracts between contractors and investors (represented as

EPMU-BLLT). Also, in each package, each Contractor shall establish an construction environmental

management plan (CEMP). CEMP are prepared in based on UEMP and more updated details to

match the conditions in each package. CEMP is the commitment of the contractor with the investor

and are tested and approved by the CSC and EPMU-BLLT.

4. SUMMARY OF ENVIRONMENTAL MITIGATIONS AND COMPENSATION MEASURES IMPLEMENTED

At the moment, the contractor of has implemented many countermeasures to mitigate the impacts and

prevent pollution. Below table will present all mitigation measures that contractor of packages has

been conducted already during quarter 3rd

2015.

Initial stage, dust generation during windy conditions such as:

- On the road at Phuoc Ly bridge

- Barrier Sai Gon Trung Luong and Phuoc Ly

During initial stage of implementation the effectiveness and focus on environmental mitigation measures was very limited from contractor side. However due to regular monitoring and instructions from CSC on environmental safeguards the situation become better in August and September particularly for dust control and waste management.

The work in ADB section started only few months ago. However the Package J2 of JICA started one

year back. The contractors are not yet fully understand the environmental requirements of the project.

Therefore the progress of Environmental management was slow initially but it is gradually improving

since the mobilization of Environmental Specialist of CSC. The Environmental specialist of CSC is

continuously monitoring the activities of all contractors and instructing them onsite as well as through

instruction letter on regular basis.

5. SUMMARY OF ENVIRONMENTAL MONITORING

The Baseline Environmental Monitoring for Air, Water, and Noise & Vibration has been done by all civil

contractors except Package 2.2 of ADB section. Result of environmental monitoring programs is

a) Comment on noise level:

Noise level in the daytime

Noise level in the daytime at two monitoring locations in baseline environment varied from 71.3 to 72.6 dBA.

In that, the average noise levels were higher than the allowable maximum of noise regulated in QCVN 26:2010/BTNMT, regulate the maximum of noise level in common areas (residential areas, the individual houses are separated or adjacent, hotels, motels and administrative agencies) period from 06h00-21h00 is 70.0dBA. It is due to the location road have a lot of traffic mean passing in the daytime. Addition, at 3,4,5 hamlet road is repairing, and have a lot of trucks. It is cause the high noise level.

Noise level in the early evening

Noise level in the early evening at two monitoring locations in baseline environment varied from 63.3to 69.3 dBA.

In that, the average noise levels were higher than the allowable maximum of noise regulated in QCVN 26:2010/BTNMT, regulate the maximum of noise level in common areas (residential areas, the individual houses are separated or adjacent, hotels, motels and administrative agencies) period from 06h00-21h00 is 70.0dBA. It is due to the location road have a lot of traffic mean passing in the time. Addition, at 3,4,5 hamlet road is repairing, and have a lot of trucks. It is cause the high noise level.

Noise level in the midnight

Noise level in the midnight at two monitoring locations in baseline environment varied from 55.6 to 59.0 dBA.

In that, the noise levels were higher than the allowable maximum of noise regulated in QCVN 26:2010/BTNMT, regulate the maximum of noise level in common areas (residential areas, the individual houses are separated or adjacent, hotels, motels and administrative agencies) periodfrom21h00-6h00is55.0dBA.

However, these noise levels meet in IFC’s guidelines regarding the noise limits for different working environment (No employee should be exposed to a noise level greater than 85 dBA for a duration of more than 8 hours per day without hearing protection)

b) Comment on vibration level:

On QCVN 27:2010/BTNMT – National technical regulation on vibration regulated for the maximum vibration in residential areas, the individual houses are separated or adjacent, hotels, motels and administrative agencies: 0.055m/s

2.

Remarks:

- Locations KK1: TSP fluctuates within 0.104 - 0.236 mg/m3. The highest value was at duration from

14 - 16h. The reason is that there are strong winds at this hot and dry duration. However, TSP is

still within the limited value (0.300 mg/m3) of QCVN 05:2013/BTNMT – average of 1h. Overall,

TSP is lower than one in previous months and baseline.

- Location KK2: TSP fluctuates within 0.057 - 0.119 mg/m3, these results are within the QCVN

05:2013/BTNMT. The same with August, results of household area in ROW nearly batching plant

and construction area are lower than one so much compare to the previous months and baseline.

That is show that, batching plant and construction activities do not cause significant impact to this

area.

- Location KK3: TSP fluctuates within 0.048 to 0.089 mg/m3, little fluctuations with times and is

much lower than the limited value of QCVN 05:2013/BTNMT – average of 1h. These values are

lower compare with baseline and the one previous month shows influences from disposal area to

the nearest population is negligible. Additionally, there is rainy season so dust content decrease

so much.

Remark:

There are shown that average values PM10 is highest at KK1 and (0.096 mg/m3), lowest value at KK3

(0.038 mg/m3). Location KK2 (new location) away from the site so PM10 concentrations is quite low,

much lower than at the old location (in the site) at all durations, respectively. However, dust values in

this month had decreased compare with baseline and previous months.

Note: QCVN 06:2013/BTNMT: National technical regulation of some toxic substances on ambient air

quality – Average of 1h.

Remarks:

There show that the value of SO2, NO2, CO, CxHy at all locations are very low and reached to QCVN

05:2013/ BTNMT and QCVN 06:2009/ BTNMT (hourly average). The results showed that the air

quality in the area is very good.

Summary: All results are within the limits of QCVN 05:2013/ BTNMT (average 01 hours). Observing

figure 4.4, by location, there can easily find content of dust at KK1 still relatively high position (in the

gate of site) due to transport activities in and out the site. Two remaining positions (out site: residential

area near the package) are much lower than KK1. Contractor has arranged two car wash stations in

the area, so dust levels are maintained below the permitted levels of regulation.

Results noise (Leq) at the monitoring location KK1



Page 47



Page 48

Remarks:

- KK1: Noise ranged from 51.1 – 65.0 dBA at daytime and 46.1 – 56.7 dBA at night (Fig 3.8). In

general, noise range at KK1 is lower significantly than the previous monitoring period; especially,

at night results has decreased very significantly. The most are fully reached QCVN 26:2010/

BTNMT (daytime: 70 dBA; night time: 55 dBA), only from 22-24h is small higher standard (56.7

dBA).

- KK2: Noise ranged from 48.1 – 61.4 dBA at daytime and 44.5 – 62.8 dBA at night. In general,

noise value is evenly all during monitoring time, and fully reached QCVN 26:2010/ BTNMT (70

dBA) at daytime. Noise levels at night are approximately standard limit (55 dBA); only on early

morning (04 - 06 am), many boats go on the Soai Rap river so noisy. The results showed that the

influence of the noise from the construction site to the nearest household is negligible.

- KK3: Compare to baseline and previous month, noise level at the daytime slight decreased, and

fell sharply at night. These results are lower than limit of QCVN 26:2010/ BTNMT.

In overall, at day and night times, noise values measured at KK1 (gate area) and KK3 (household near

Disposal No.1) significant decrease at night and the most of results are lower than allowable limits

(QCVN 26:2010/BTNMT – 55 dBA). The volume transport had decreased and bored pile works reach

90% of the volume so pressure transport excavated from the site was no longer as large as the

previous month.

Water quality for irrigation, irrigation or other purposes with requirements similar water quality.

Remarks:

a. pH index

Evolutions of pH clearly demonstrated by the following figure:

Change of pH index at the monitoring locations

Through above Figure, it can be seen that fairly uniform of pH index between the monitoring locations,

there was not significant difference between high and low tide at the same location. All values are

within the permissible limits of QCVN 08:2008/BTNMT-B1.

Page 54

b. Total Suspended solids (TSS), turbidity:

Change of TSS clearly demonstrated by the following figure:

Change of TSS at the monitoring locations

TSS concentration is still high. All values at low tide exceed QCVN 08: 2008/BTNMT-B1. TSS and

turbidity at low tide are higher than one of the high tide at each location. Boats density in this region is

very large, has stirred flow leads to turbidity and TSS concentrations increase.

c. Assessment of organic pollution (DO, COD, BOD5 index)

Change of DO, COD, BOD5 index clearly demonstrated by the following figures:

Change of DO index at the monitoring locations

Page 55

Change of BOD5 index at the monitoring locations

Change of COD index at the monitoring locations

DO, BOD5 and COD index are used to denote the degree of organic pollution in the water, through the

figures of 4.25, 4.26, 4.27, and shows the surface water near the project area as follows:

- The average of monitoring locations ranged from 4.53 to 5.09 mg O2/L, completely achieved

QCVN 08:2008/BTNMT-B1.

- The average of BOD5 ranged from 5 – 12 mg O2/l, completely reached the limit of QCVN

08:2008/BTNMT-B1.

- The COD also have similar characteristics BOD5, and meet QCVN 08: 2008/BTNMT-B1.

d. Assessment of nutrient pollution (NO2-, NO3

-, PO4

3-)

Change of NO2-, NO3

-, PO4

3- clearly demonstrated by the following figures:

Page 56

Change of NO3- at the monitoring locations

Change of PO43-

at the monitoring locations

Value of NO2-, NO3

-, PO4

3- are used to denote the degree of nutrient pollution in water, the results and

the morphological of graphs show that there are not absolutely surface water nutrient pollution signs

yet at here. The results of PO43-

are very low, below the permissible limit of QCVN 08:2008/BTNMT-

B1, even at A2. NO2- parameter that is an indicator to determine the trace contamination is completely

undetectable. NO3- values are higher than baseline and the previous months so still much lower than

QCVN 08:2008/BTNMT-B1. This creasing maybe natural elements, because NO3- value at NM(D2) is

the same although its location away from the project.

e. Heavy Metals

All heavy metal concentrations were lower than the permitted level of QCVN08: 2008/BTNMT-B1

many times. Indicators such as Fe, Al, As, Hg, Cd, Pb were not detected.

f. Oil and grease

Value analysis shows that water quality at areas potentially contaminated less level due to the

Page 57

influence of the busiest traffic activities in this area. However, values achieve QCVN 08: 2008/BTNMT-

B1.

g. Microbiology

Change of Coliform total at the monitoring locations

Overall, coliform values are much lower than QCVN08:2008/BTNMT-B1. The average values show

that there are not many differences between locations.

h. Remarks at the NM(D2): surface water on Rach Dia River nearly the Disposal No.2:

Overall, most values are much lower than QCVN08:2008/BTNMT-B1. Monitoring results showed not

yet significant changes in the physicochemical properties of water sources compared to the previous

monitoring period. The pH value is lower than the previous month due to sampling time (previous

month: high tide; this month: low tide). Solids suspended (TSS) in water measured at 75 mg/l, higher

than QCVN08: 2008/ BTNMT-B1 (50 mg/l). However, probably due to the rainy season and water

resource characteristics inherent in this area because excavated soil volume to disposal area No. 02 is

less than previous month.

will continue to maintain the control measures to ensure the quality of waste water in accordance with

the current regulations.

7. KEY ENVIRONMENTAL ISSUES

The contractors lacking in many issues as far as Environmental safeguards of ADB and JICA are

concern. However there are few critical issues which should be comply by the contractor immediately.

1. All contractors from ADB section has not mobilized there Environmental Officer so far. Even

none of these contractors have not submitted the CV of their environmental officer in CSC

office for approval. The employment of full time Environmental officer is part contract

agreement with EPMU. It is clearly stated in Technical specification Volume-III, section

01300, and para 1.3 that “contractor shall appoint an Environmental Officer with

environmental/social qualifications who shall remain in place for the duration of the contract

period and be responsible for ensuring implementation of all the contractor’s responsibilities

regarding environmental issues” . However till now no action has been taken by any

contractor in this regard.

2. Also as per the contract agreement contractor shall submit the monthly environmental

progress report to CSC office for every month. So far no contractor has submitted the report

in CSC office. However contractor of JICA section is submitting this report in CSC office.

Page 60

3. All the contractors are procuring aggregates and sand from the local supplier of these

material as they have not borrowing these material from their own quarries. As per the

national legislation of environment the contractor may use this construction material from

those sources which has valid permission/ approval of Natural Resource and Environment

Department. The CSC has asked all them to submit the copy of valid permission/ approval

of Natural Resource and Environment Department, obtained by the owner of

aggregates/sand quarry. So far no one has submitted the documents in CSC office and

working without legal approval. However the CSC has issued then letter of warning and

instructions.

4. It is requirement of national law to obtain the approval certificate for machinery and vehicles

used for construction purpose. So far none of the contractor has submitted these certificates

in CSC office.

5. There is huge unsuitable soil which will be disposed at some locations already approved for

disposal of unsuitable material from Natural Resource and Environment Department.

However so far no contractor has submitted the complete documents of approval of

disposal site.

8. COMPLAINTS

The project area is located near many residential locations also the proposed alignment is passing through many agricultural fields and semi urban area. So far no complaints have been recorded for environmental issues. However there are complaints for resettlement & rehabilitation and land acquisition issues. Rredressedal of these complaints have been done. The complaints and how these complaints settled are given in Table 5.

Most of the complaints of affected households have been settled by the Executing Agency with the help of concerned people’s committee of province, district and commune. However, even after best efforts of the executing agency, there are still few cases of dispute and grievances, which are being redressed as on priority.

Table 5. Settlement of complaints

No. District The Issues and Redresssal status

1. Ben Luc District 01 HH (Nguyên Viêt Cương) are under disputes, the case was in the court and the land was paid to its owner in accordance to the Court decision, (only assets are being disputed now).

In addition, 28 tombs were found without owners during site clearance. Local authorities are preparing to remove within October, 2015.

2 Can Giuoc District Almost 93 % area of acquired area is paid, however, remaining few HHs and TL Shoes Company adjacent to HCMC are, disputed due to difference in compensation rates between 2 provinces.

3 Bình Chánh District:

Almost 86,24ha of land out of 123,14ha, about 70%, has been paid and handed over to contractor.

The major obstacles (between Km 16+600-16+900), which causing inconveniences, are the land of 3 affected persons, who are partly paid:

Mr. Doan Van Tu, C14/271, Village-3- Da Phuoc Commune, Binh Chanh District (2180 M2)

Mr. Thai Van That, Village-3- Da Phuoc Commune, Binh Chanh District (9679 M2)

district, Ho Chi Minh City, promised that he has allowed the Contractor to commence the work for service road and after receiving the rest (near 500 mil.VND) of compensation, he will hand over the rest (near 2000 m2) of compensated land within a week to facilitate the construction work;

The two others affected persons have, lodged grievances before compensation committee for additional compensation, as excess land and trees are falling within the corridor. The Compensation committee Binh Chanh District communicated that the documentation for additional compensation for households Thai Van That and Nguyen Van Ke in village 3, Da Phuoc commune, Binh Chanh district, Ho Chi Minh City; is under process and will be ready and submitted to the Binh Chanh district people Committee for approval, which may take at least 2 weeks’ time and after availability of fund they will be able to pay the compensation.

The remaining areas are of NH 1 and NH 50 intersections.

9. CONCLUSION AND RECOMMENDATION

The construction work is already in progress in four civil contact packages of ADB and one civil contract in JICA section. These contractors have mobilized construction machinery and manpower on site. The contractors are not fully understood the environmental safeguards required for project implementation. The main focus of all these contractors is to achieve the physical work progress. The mindset of contractor and workers is that they will care for environmental safeguards in those situations where there is no conflict with the physical progress of work. It will take some more time to prepare them mentally that if they will take care of environmental and social safeguards then only the physical progress can be achieve swiftly.

There is some statutory permission which has to be obtained by contractor without any further delay as there is already significant delay in obtaining these permissions.

The contractor has to seriously consider the issue of waste disposal, facilities in labour camps, electric hazard issues of batching plant, water treatment facility in batching plant. The locations of all batching plant is near river so contractor has to construct the fencing around the batching plant so that there should be no contamination of river water from waste water and solid waste generated in the batching plant.

Also the safety of labours and workers is very important so there should be training program of health safety and environmental awareness for all work forces at regular interval.

There should be training for divers also so that while driving the vehicles through residential areas and environmental sensitive area all drivers take care of noise and air pollution and disturbance to local communities.
