prolonged flood and drought to the local economy and society.



64

The Project will support GoV to carry out structural and non-structural actions for the

preparation and management of disaster risks related to floods and droughts. Floods and

droughts will be mitigated by positive impacts of the project. Strengthening capacity and

improving management process is one of project’s results. Specifically:

- Upgrading irrigation infrastructures include: Dredging, expanding 77km of

channel; reinforce 60km of embankment and rural road; construct regulator

drainage system, traffic bridge; construction of 3.25km embankment to improve

flooding drainage and to ensure safety of people as well as irrigation water source

providing to 185,872ha of agricultural land;

- Enhance community capacity to manage floods and droughts with the activities

focused on some communes in project area;

- Regional cooperation to manage negative issues such as climate change, sea level

rise and border overflowing flood; building design standards of flood and drought

in the Mekong Delta with the cooperation of MRC and the participartion of

Mekong riparian countries.

Thoi Tien subproject

- 12-13 November, 2017: Conducting the site survey of cilvil package GMS 2.9 – Cai Cai

channel subproject

CSC monitoring: For each bidding package, IEMC has set up an environmental

monitoring form according to EMP provided for CSC. CSCs have responsibility to carry

out environmental protection measures everyday basing on environmental monitoring

form and synthesize it in monthly reports. In periodically monitoring phases, IEMC will

review those monthly reports to assess compliance with environmental protection

measures of construction contractor.

Community consultation: Recording people’s reflection on environmental issues at

construction site as well as environmental sanitation safeguards of contractors during

construction.

4.2. Environmental protection measures to be performed

IEMC has synthesized Table 4 according to environmental protection measures proposed

by EMP and compliance with environmental mitigation measures of contractors based

Remark:

On site, the environmental protection measures in general have been implemented

relatively enough such as daily cleaning up the site, performing labour safety measures

(construction signs, first-aid box on site…). Besides, construction activities of contractor

don’t cause negative impacts to surrounding residential areas – contractor doesn’t

perform construction activities at nighttime and almost no machines with large noise.

- For the bidding package GMS – 2.6: Basically, contractor in charge of the

construction of Nguyen Van Con sewer, Saliset sewer and Son Quy sewer has

carried out well environmental protection measures on site. However, vehicle

washing station has not yet been set up on site.

- For the bidding package ICB GSM -2.7: Construction of flood control system in

Ba Rai – Phu An region, Tien Giang province. It is necessary to strengthen

measures as sparying water to reduce dust and installing more traffic signs as well

as setting up fence at deep pits on construction site

- For the bidding package ICB GSM - 2.8: Thuong Thoi Tien embankment:

construction has been already completed

- For the bidding package ICB GSM - 2.9, “Improvement and upgrading irrigation

channels and supply irrigation water for Plain of Reeds”, in monitoring phase of

quarter IV, IEMC team found that the construction of cell 2 is not match in

comparison with the original design even the contractor has been reminded by

IEMC in the previous monitoring phase. The contractor has cooperated with local

authority to satisfactorily resolve people’s complaints at Cell no.3

Noise ranges from 63 to 68dBA. (Noise<70dBA).

The analysis results show that mitigation measures of dust have been carried out fairly

good thereby mitigating negative impacts of dust to ambient air environment. However,

sometimes, gathering construction machineries and equipment had increased noise in

project area but its impact is localized and in the short time.

➢ Surface water quality

Surface water sampling locations are linked with construction sites of culverts: Nguyen

Van Con, Salisete, Son Quy.

Based on analysis result and QCVN08-MT:2015/BTNMT – National technical regulation

on surface water quality, column B1: using for irrigation purpose show that parameter

Coliform exceeds 1,14- 1,96 times allowable limit. The remaining parameters are within

allowable limit. Basically, construction activities have not caused the increase of surface

water pollution on the channel.

➢ Ground water quality

Ground water sampling locations are is to determine how influence levels of construction

activties affect ground water quality.

Based on analysis result of general ground water samples and QCVN 09-

MT:2015/BTNMT – National technical regulation on ground water quality show that:

- pH, hardness, salinity, COD, NH4+, NO2

-,NO3- and heavy metals Fe, Pb, As, Zn,

Pb, Hg of ground water samples are within allowable limits.

- Coliform parameter of samples exceeds allowable limit from 5 to 6.3 times.

- Undergournd water quality is not affected by installing culvert pipeline because

the depth of installed culvert pipeline is insignificant. Nomarly, depth of access to

ground water is about 200m.

➢ Soil environment

Soil sampling locations are linked with construction activities, installation of culverts:

Nguyen Van Con, Salisete and Son Quy.

Analysis result of 03 soil samples will be compared with QCVN03-MT-:2015/BTNMT –

National technical regulation on heavy metal limit. Concentration of some heavy metals

such as Zn, Pb, As, Cd is in allowable limits. Gathering soil/mud does not cause ambient

environmental pollution. However, contractor should be fenced up material gathering

area for environmental sanitation.

Air sampling locations are linked with areas, where are going to construct culverts:

Giong Tre 1, Thong Luu, Cai La, and Tham Ron.

The air sampling locations are connected to materials transportation route of Cai Cai

channel construction site, the Plain of Reeds subproject.

- Contaminants such as NOx, SO2 and CO are in allowable limits of

QCVN05:2013/BTNMT. The current status of air environment is fairly good

because project hasn’t been constructed.

channel construction site, the Plain of Reeds subproject.

Based on QCVN08-MT:2015/BTNMT - column A2 - National Technical Standards on

surface water quality used for domestic water supply but appropriately applied treatment

technology, shows that:

- pH ranges from 6.4 to 7.8 and in allowable limit of QCVN08-MT:2015/BTNMT,

column A2

- Parameter Dissolve oxygen (DO) of M1, M2, M5, M6 and M7 does not achieve

allowable limit of QCVN08-MT:2015/BTNMT.

- BOD5 parameter of some surface water samples M1, M2, M5, M6 and M7 exceeds

allowable limits from 1.26 to 2.35 times according to QCVN08-MT:2015/BTNMT,

column A2.

- COD parameter some surface water samples M1, M2, M5, M6 and M7 exceeds

allowable limit from 1.19 to 1.36 times according to QCVN08-MT:2015/BTNMT,

column A2

- NO2- parameter of surface water samples M1, M2, M5 and M6 exceeds allowable limit

from 5 to 8 times according to QCVN08-MT:2015/BTNMT, column A2

- Parameters NH4+, NO3-, Pb, Hg, Zn, As are in allowable limits of QCVN08-

MT:2015/BTNMT. Currently, the project has not been constructed so there are no

construction activities affecting surface water quality. Surface water pollution could be

arised by daily activities of local people through littering and discharging domestic

wastewater into the channel.

The results of analysis show that there is not much different compared to the current state

of water environment before construction. That also means the construction activities of

the project do not increase pollution to the water environment, and the constractor

performed the mitigation measures well.

Surface water quality along embankment system applied QCVN08-MT:2015/BTNMT –

National technical regulation surface water (column A2: should apply appropriate

techiques before using for living purpose and water supply) at 04 monitoring locations:

first point of embankment system (M1)., Ngang wharf (M2), Tan Chau ferry terminal

(M3) and final point of embankment system (M4). Specifically:

Parameters such pH, heavy metal, oil and grease are in allowabe limit according to

QCVN08-MT:2015/BTNMT. Tien river water along construction area has signs of a

slight organic pollution with parameter COD at 04 sampling locations exceeds QCVN

from 1.01 to 1.12 times. BOD5 of samples M1, M2, M3 exceeds QCVN08-

MT:2015/BTNMT column A2 from 1.01 to 1.18 times. Water source in those places has

signs of microbiological pollutiom. Parameter Coliform in ¾ the number of samples

exceeds QCVN from 1.1 to 2.2 times. Analysis results show that surface water resource

is polluted by organic matters. Organic pollution is arised by daily acitivities of people

along Tan Chau ferry, Ngang wharf not completely caused by construction activities. The

analysis results aslo show that there is no significant decrease of concentration of

pollutants compared to which mentioned in Quarter IV, 2017.


Soil sampling locations are linked with construction area of Thuong Thoi Tien

embankment and road (along Tien riverbank)

Based on analysis result and QCVN03-MT:2015/BTNMT – National technical regulation

on heavy metal limit in soil shows that:

Concentration of some heavy metals such as Zn, Pb, As, Cd is not exceed and in

allowable limits. Gathering construction materials wouldn’t cause the increase of soil

environment pollution.


Soil sampling locations Đ10, Đ11, Đ12 are linked with dredging activities of Cai Cai

channel. Remaining soil sampling locations are going to link with dredging activities of

channels: Thong Nhat, Tan Cong Chanh and Khang Chien.

Analysis result shows that all parameters analyzed achieve allowable limit QCVN 03-

MT:2015/BTNMT – National technical regulation on heavy metal limit in soil. Gathering

dredging mud at disposal site on construction site does not cause ambient environmental

pollution

M12 and M14 exceeds allowable limit from 1,09 to 3,1 times according to QCVN08-

MT:2015/BTNMT, column A2.

Surface water pollution could be arised by daily activities of people along channels such

as discharging domestic wastewater, waterway traffic activities. However, there is no a

significant change on water quality of channel before construction. It can be understood

as mitigation measures of surface water pollution have been carried out fairly good by

contractor.

6.2. Grievance Redress Mechanism (GRM)

For each subproject, GRM has been already set up to solve people’s complaints.

Specifically:

- On construction site, it has been set up bulletin board with comprehensive information

on subproject, Construction unit, CSC, Investor, Site manager and address, phone

number for Investor communication

- For each subproject, PPMU has already assigned its staff, who always show up on

construction site accompanying with CSC’s staff and Site manager.

- If occurring any complaints, people are able to directly contact with Site manager, CSC

and PMU’s representative through phone number mentioned above. On the other hand,

people can propose their complaints on environmental issues on construction site for

resolving, overcoming and compensation.

- If two parties could not make a deal, people can send their complaints to representative

of Subproject management unit, CSC, Site manager on site or send it to Subproject

management unit’s headquarter. Within one month after receiving complaints, Director

of Subproject management unit will in charge of complaints, apponit staff to reslove

relevant parties including Site manager, representative of Subproject management unit,

CSC and affected people on compensation and overcoming consequences.

- If it is not sastifed, people can pursue their case to the higher level government for

settlement

In 7th monitoring phase 2017, there were some people’s complaints recorded as

following:

1) Bidding package GMS 2.7: Construction of flood control system in Ba Rai –

Phu An region, Tien Giang province

- There are 02 households near construction area of Thong Luu sluice

complained of cracking their housing, however, this issue has already been

addressed by the contractor and no complaints arisen. 2) Bidding package GMS 2.9: Improvement and upgrading irrigation channels,

and supply irrigation water for Plain of Reeds, Dong Thap province

- In construction area of Cell no.3, Thi Son village, Tan Thanh A ward, Tan

Hong district, PMU has received people’s complaints on alum infection in

their paddy farms and aquaculture ponds. On 12 October, 2017, local

authority cooperated with the contractor and affected people for surveying

and identifying causes of the issue. The results show that paddy farms and

aquaculture ponds infected with alumn due to non-regularly checking the

embankment of paddy farm as well as deliberately embankment to change

the flow. Thus, it is considered as not related to the construction unit, the

meeting minutes are attached at Appendix of the report

7. INSTITUTIONAL STRENGTHENING AND TRAINING

Environmental monitoring and training program for CSC and contractors

IEMC found that environmental sanitation issues on construction site have not been

addressed by contactors and CSC and weekly monitoring forms have not updated



72

regurlarly. For 5 November to 13 November, 2017, IEMC group has visited to

contractor’s head offices to performe training on 3nd environmental monitoring with

participation of Investor, CSC and contractors. The main contents of environmental

monitoring and training class included:

- Representative of PMU’s leader made a speech, introduced about the project,

project’s implementation and progress as well as stated the reason of traning

course.

- Consultant gave environmental monitoring documents to CSC, contractors and

presented the content of environmenta monitoring and training program

- Beside, consultant also guided on how to use environmental monitoring form and

schedule to submit it to PMU

Comments and results obtained:

Consultant explained clearly objectives, contentson environmental protection and

management measures to CSC and contractors as well as remind them to comply with

management measures, environmental protection during project construction phase.

During construction process, contractors and CSCS will coordinate with PMU to control

the implementation of environmental minimization measure tighly and will be

respobsible to overcome environmental issues arise.

PMU’s hot line has provided already to strengthen effectiveness of risk control,

environmental incidents and collects information, environmental pollution issues arising

during project implementation.

9. CONCLUSION AND RECOMMENDATION

9.1. Overall Progress of Implementation of Environmental Management Measures

- The contractors have carried out environmental minimization measures however it

still have had shortcomings. Contractor should follow environmental minimization

measures, which mentioned in environmental management plan (EMP). Environmental

impact assessment and environmental monitoring documents of the Project also were sent

to contractors and CSC thereby strengthening environmental management plan as well as

minimization measures.

- The bidding package GMS 2.6 and 2.7: Contractors and CSC have paid attention

to adjust mitigation measures as menioned in EMP. Contractors have implemented

mitigation measures of dust, however, it is necessary to set up vehicle cleaning

stations on site.

- The bidding package ICB GMS 2.8: Construction almost completed so no

environmental issues arisen in monitoring phase

- The bidding package GMS 2.9: Huyen Minh contractor constructed Cell no.2 not

match with original design. Huyen Minh contractor must quickly implement

corrective measures before conducting next construction activities in order to

ensure communities’ safety as well as preventing the collapse of Cell no.2

- CSC’s periodically environmental monitoring reports have not submitted on

schedule

9.2. Action Recommended

- PMU, CSC and IEMC will continually coordinate construction monitoring and

environmental management. CSC and contractors should follow EMP to carry out

environmental minimization measures on site better.

- Recommends CSC carrying out seriously environmental monioring forms and

submits these forms to the staff of PMU for the preparation of plans to promtly solve

environmental issues as well as incidents.

- Recommends CSC and contractor maintaining and ensuring fully workers’ safety

condition such as camps. labor protective gears. medical kit on site. etc… subproject

PMU should supervise. check and remind contractors to implement those safety

condtions.

- IEMC will conduct environmental monitoring in January, 2018.
