1st Semi-annual Environmental Monitoring Report 2013

Mong Duong (2 x 500MW) Thermal Power Plant Project

Page 5 of 68

EXECUTIVE SUMMARY

The Mong Duong 1 Thermal Power Plant project has been classified as category A1 in

accordance with ADB’s Environmental Assessment Guidelines (2003). The Project EMP was

developed as an integral part of the Environmental Impact Assessment (EIA) process of the

Project that was completed and approved by ADB in 2006.

To ensure that negative environmental health and safety impacts are minimized and addressed

effectively throughout the project implementation and operational phase, an environmental

management plan (EMP) has been formulated detailing mitigation measures and a monitoring

program during various project phases of the Mong Duong 1 Thermal Power Plant project,

located in the northern province of Quang Ninh (Vietnam)

The report is highlighting on the environmental monitoring tasks and quality observations

performed by the various project entities on air & noise, vibration, water quality, aqua culture

and fishery development and a chapter on mangrove reforestation. It is further reporting on

health & safety issues at site as well as on social impacts on the affected communities including

gender issues related to man and women working together on the same project and sharing

common camp facilities.

It covers the works implemented during the period January to July 2013 and provides a summary

of current problems, conclusions and recommendations how to best mitigate the impacts on

affected parties and the environment.

The following environmental aspects were looked at for environmental compliance and

monitored for environmental quality during the reporting period

Air and noise quality

Water quality

Aquaculture and fisheries status

Mangrove reforestation

Health, Safety and Environment (HES)

Social impacts and Gender issues

Problem areas inspected for environmental compliance and monitored for environmental quality

during the reporting period relating to Air & Noise, Vibrations, Water quality and Aqua culture

were more affected in the current reporting period compared to the last 6 months period, mainly

due to the increased level of activities at the construction site or nearby locations serving the

Mong Duong project.

Air & Noise and Vibration Issues Regarding Air Quality comparing the monitoring results (dust) of affected areas between the last

6 months of 2012 and the first 6 months in 2013, it shows that the first 6 months of 2013 has a

higher concentration of air pollutants than the 6 months before, especially in the 3 months April,

May and June 2013 when the weather was dry, sunny and hot. The increase is mostly due to

increased traffic on the new no.18 and old 18A road likewise.

On the new no.18 road near the entrance of Mong Duong 1 and 3 2 power plants, heavy vehicles

travel a lot so the road is very dirty and dusty. The road needs regular water spraying to improve

the conditions, especially in the dry season. The appearance of construction waste in nearby

vacant land (along the new no.18 road such as concrete from bored piles and other construction

debris needs to be removed and kept neat and tidy at all times. Wheels of construction vehicles

leaving the site need to be cleaned before entering the public road. Excavated areas and heaps of


Mong Duong (2 x 500MW) Thermal Power Plant Project,

Page 6 of 68

backfill on the site shall be sprayed with water or covered with plastic sheeting to limit dust

migration to nearby residential areas.

Through 6 monitoring times of noise quality at the working site during 2 days each in the period

February to June 2013, the results show that the noise level monitored in 1 hour at the turbine

and boiler area is about 73,4 – 82,1 dB(A). Compared with the allowable noise level for the

working place they are lower than the allowable limit value in TCVN 3985:1999 (85 dB). And

the noise level during daytime from 7AM to 8AM and 5PM to 6PM are 0,7–2,6 dBA higher than

the allowable limited value in QCVN 26:2010/BTNMT. At nighttime the noise level is between

10PM and 11PM monitored at a point about 7m away from the road are also higher by 7,1-12,4

dBA than the allowable limited value in QCVN 26:2010/BTNMT

The increase in noise level at the various locations and times are mainly caused by increased

construction activities at site and material transports from and to the construction site on the old

18A road

Noticeable environmental impact during the reporting period has not only been caused by pile

driving activities, foundation digging, construction and soil conveying, but also due to social

environment changes caused by the gathering of the large work force in the Mong Duong

precinct which causes all sort of problems including increased traffic, particularly in the early

morning and evening time, when a large contingent of the labor force for both projects enter the

work space

In order to limit the noise level at Residential areas, particularly at night time, the Contractor

shall be requested to keep heavy construction works to day times and limit vehicle movements

after 10PM to a minimum required.

Through 6 monitoring times during 2 days each in the period February to June 2013, the

monitoring results for vibration levels at two (2) locations during the period 6AM to 9PM are

lower than the limited value permitted in QCVN 27:2011/BTNMT – National Technical

Regulations on vibration.

No issues at present. Furthermore since heavy construction activities are almost entirely

implemented during day time, no vibrations are experienced at nighttime

Water quality

Water quality is monitored for underground water and coastal water and results are

Almost all tested items of underground water at the sampling sites are within the limits of

the National technical regulation on underground water quality QCVN09/2008/BTNMT

except for (Cd) and (Cl-) content and content of micro-organisms (Coliform)

Concentration of microorganisms (Coliform) beyond permissible limits of the National

technical regulation on underground water quality were found at the sampling points of

PW-01, PW-02, PW-03, PW-04, PW-05, PW-06, PW-08, PW-09. This is explained by

the fact that water in existing wells are not usually utilized thus the water is not rotated

and easy to create conditions for microbial growing.

Concentrations of chloride (Cl-) beyond permissible limits of the National technical

regulation on underground water quality were found at the sampling points of PW-03,

GW-01-D, GW-08, GW-09 and GW-11. This is explained by the fact that the sampling

sites are located in the coastal areas, thus may be lightly saline



Page 7 of 68

Impact of obstacle removal activities in coastal surface water is monitored by coastal

surface water sampling sites. Parameters of them are all within limit in comparison with

QCVN 10: 2008/BTNMT

Impact of Mong Duong river alignment activities in coastal surface water is monitored by

coastal surface water sampling sites. Parameters of them are almost within the limit in

comparison with QCVN 08: 2008/BTNMT

Impact of transport activities in coastal surface water is monitored by coastal surface

water sampling sites. Parameters of them are within limit in comparison with QCVN 10:

2008/BTNMT

Two of the heavy water pollution sources are water discharged from coal mining areas

via the Mong Duong river and barges transporting coal in the nearby waterway. Spilled

coal from barges will dilute elements and compound to coastal waters.

In order to compensate for the two wells which were covered during the initial site fill activities,

the contractor should be requested to drill two additional wells with a depth of 25 to 30m to

ensure water quality sampling can be done at lower aquifers. Currently this is restricted to a

depth of 15m.

Contractor must maintain all current measures to avoid pollution of surface and underground

water resources by strict control on solid and liquid waste dumping and/or accidental spillage of

oil and chemicals.

To offset the problem of the polluted water discharge from coal mining activities, treatment of

discharged water from the coal mining process and a reduction in coal smuggling activity would

greatly improve the quality in the water way, but this may be difficult to achieve.

Aquaculture and Fisheries

Based on the results of the two surveys on fishing and aquaculture activities in Thac Thay, De

Dach and Mong Duong rivers and along the coastal line of Cam Hai commune during the first

half of 2013, it may be concluded that the construction phase of Mong Duong 1 power plant has

minor impacts on the aquatic resources in the inspected areas. There were no fishing activities in

De Dach and Mong Duong rivers due to heavy industrial pollution from mining and coal trading.

Number of aquatic species and their components in these areas are very limited. Some fishing

activities were observed in the Thac Thay river and Luong Gac areas, but there are no shrimp

activities along Cam Hai coastal line due to loss from shrimp diseases outbreak and flooding.

Normal fishing activities and aquaculture species are observed in the Thac Thay River and along

the coastal line of Cam Hai commune.

To reduce impacts of pollution from mining and coal trading, Contractor is strictly enforced to

execute the solid and liquid waste disposal management plan and prohibited dumping of

hazardous substances into nearby rivers and coastal water.

Mangrove Reforestation Program

To compensate for the loss of mangrove forest taken by the Mong Duong Project, 52ha of

mangrove has been re-planted in Dong Rui Commune, (Tien Yen district, Quang Ninh province)

Inspection result shows that mangrove quality develops well, branching off well, in the allocated

area of 52 ha of mangrove forest which was replanted, there is 95% survival rate of plants.

With the current results, the Mangrove planting project has met the requirement of ADB’s EIA.



Page 8 of 68

To sustain the good results, continuous protection and feeding of the mangrove is a must to

ensure their good development and branching off. Activities such as tree clearing, weeding and

replanting of failed areas must also be maintained

Dumping of waste in mangrove and forestry areas and resource extraction from mangroves and

plantation forestry areas must be prohibited

Health & Safety and Environment

Monitoring consists of daily observation and inspections of environmental pollution, soil

contamination, fire hazards, labor and site safety and other health or safety hazards. This topic

does not belong to the monitoring scheme of the assigned environmental experts of the

Consultant, but is observed and monitored by the Owner’s Consultant Site supervision staff

during their daily work activities and by the Consultant’s Occupational Health and Safety expert.

Current results show

Good overall performance of the EPC contractor’s appointed HSE team with the

Environmental Officer (OE) appointed as per the Contractor’s EMP

Good site safety management of the EPC contractor with regards to fire safety, plant and

equipment safety, labor safety, worker training before and access gate checks before

entering Site.

No fatality and No Lost Time accident occurred until now with the accumulated total

man-hours of 5’200’000 as of July 2013

No serious soil issues happened at site until now besides some small oil spillages which

were treated immediately as per the Contractor’s EMP

Waste management follows the contractor’s EMP by separating waste into different

groups and collected and disposed as per the EMP requirements.

All required permits are in place ie. Permit To Work, Confined Space Entry Permits, Gas

Test Certificates etc.

First Aid service is available 24/7

In order to maintain the good standard the EPC contractor must strictly enforce the site safety,

warn offenders and in repeat cases dismiss them from site (some recent incidents shown in the

attached pictures need to be corrected)

Newly legislated and/or revised environmental laws must be carefully examined in order to

determine whether or not they are required to be implemented during the project execution

Contractor has to ensure at all times that it complies with the EIA and the requirements specified

in chapter VI of the ADB environmental assessment guidelines, 2003. Contractor should once

every 6 months organize exercises based on likely accident scenarios at site in which the

contractor’s assigned key site personnel assumes their emergency response roles and periodically

evaluate the efficiency of the Project EMP in place.

Social and Gender Aspects

Most current results show that both men and women are well informed of potential health and

safety risks: HIV/AIDS control and prevention activities for both camp workers and offices were

carried out by the EPC contractor to educate awareness on personal hygiene and sexually

transmitted diseases. Drug education for construction and office workers are implemented and



Page 9 of 68

undergo test screenings every 6 months for early detection and manage health issues. Camp

workers and construction office workers are vaccinated and regularly checked for diseases by

healthcare provider taking care of construction workers and local villages.

A recent audit at one of the contractor’s labor camp (LLM 69.1) showed excellent results. The

rooms for women are in good condition and include bath room and toilet inside. Television and

Air conditioner are also provided. Water supply is from underground well treated by RO system

before using. Water is tested frequently for its safe use.

The condition of the site toilets is good with separate toilets available for both men and women.

Currently 76 toilets are provided at the Mong Duong 1 site for some 3’000 workers. They are

cleaned daily. As per the EPC contractor’s information the percentage of female workers is

approximately 15% split in field and office staff.

It is suggested that the Owner’s Consultant will continue to perform regular audits at the

contractor’s labor camps, especially with regards to gender issues, at the contractor’s offices and

at the construction site itself, to ensure the good standard regarding sanitary conditions is

maintained throughout the project construction phase.

1. INTRODUCTION

1.1 The project

The Government of Viet Nam has requested assistance from the Asian Development Bank

(ADB) to part finance the construction of the Mong Duong 1 Thermal Power Plant (under Loan

No.2350, and 2610). The Project is a coal-fired, thermal power electricity generation project with

a generation capacity of 1,000 MW. The overall project comprises of two power plants on the

same plot of land with an ultimate generation capacity of 2’200 MW. The Mong Duong 1 power

plant will comprise of two 500 MW generating units, and associated supporting infrastructure

whereas the Mong Duong 2 power plant built under a BOT scheme comprises of two 600 MW

generating units.

The MD1 project has been classified as category A1 in accordance with ADB’s Environmental

Assessment Guidelines (2003). The EMP was developed as an integral part of the Environmental

Impact Assessment (EIA) process of the Project that was completed in 2006.

The Mong Duong 2 power plant project is not part of this report, although it may contribute to

the overall impact on the environment as the two plants are back to back located on the same

piece of land.

1.2 Incorporation of Environmental Requirements into Project Contractual

Arrangements

To ensure that any possible negative environmental impacts are minimized and addressed

effectively, an environmental management plan (EMP) has been formulated detailing mitigation

measures and a monitoring program during various project phases. The individual monitoring

tasks and its frequencies are determined by the EIA and the approved staffing plan of the Project

2.2.7 Health, Safety & Environment Inspection and Result

Current audit results show that both men and women are well informed of potential health and

safety risks: HIV/AIDS control and prevention activities for both camp workers and offices are

carried out by the EPC contractor to educate and promote awareness on personal hygiene and

sexually transmitted diseases. Moreover, drug education and awareness for construction worker

and office workers are implemented and have regular test screenings every 6 months to early

detect and manage health issues. Camp workers and construction office workers are vaccinated

and regularly checked for diseases by healthcare provider services taking care of construction

workers and local villages.

A recent audit at one of the contractor’s labor camp (LLM 69.1) showed good results. The rooms

for women are in good condition and include bath room and toilet inside. Television and Air

conditioner are also provided. Water supply is from underground well treated by RO system

before using. Water is tested frequently for its safe use.

The condition of the site toilets is good with separate toilets available for both men and women.

Currently 76 toilets are provided at site for 3’000 workers. They are cleaned daily. As per the

EPC contractor’s information the percentage of female workers is approximately 15% overall

split in field and office staff.

HDEC’s Health, Safety & Environment Inspection and Findings are presented in Table 4

2.2.8 Personal Protective Equipment (PPE)

All employees of the EPC contractor and all its subcontractors working, or anyone visiting the

work area, are required to wear hard hats (with exception of office, cafeteria, accommodation

and vehicles), safety shoes, high visibility vests and fluorescent gathers coverring the ankles

above the safety shoes. The use of safety harness is compulsory when working at heights greater

than 2 meters above ground. Safety harness to have double clip arrangement so the wearer is

always secure.

2.2.9 Security Status

EPC contractor has placed security guards 24/7 at all the access gates. (Main gate, CW

intake and material laydown area)

All gates implement inspections for workers and vehicles to prevent theft.

EPC contractor has prepared PPE for visitors at the main gate and check all workers and

vehicles if they have valid ID’s and/or vehicle cards

2.2.10 Social Aspects and Gender issues

This needs be reported regularly as a major concern for women and men throughout the

construction phase. The health issue of the labor force is one of the topics that requires close

monitoring as part of the health and safety management plan.

Current results show that both men and women are well informed of potential health and safety

risks: HIV/AIDS control and prevention activities for both camp workers and offices were carried

out by the EPC contractor to educate and promote awareness on personal hygiene and sexually

transmitted diseases. Moreover, drug education and awareness for construction worker and office

workers alike are implemented and have regular test screenings every 6 months to detect early

and manage health issues. Camp workers and construction office workers are vaccinated and

regularly checked for diseases by healthcare provider services taking care of construction

workers and local villages.

2.3 Conclusions and Recommendations

Conclusion

Good performance of the EPC contractor’s OHS.

Good site safety management of the EPC contractor in having all required permits in

place ie. Permit To Work, Confined Space Entry Permits, Gas Test Certificates etc.

Check list available for environmental performance monitoring program done weekly by

EPC contractor

First aid service available 24/7

Monthly and semi-annual reports issued to the Department of Labor Quang Ninh

province

A recent audit by Owner/ Consultant’s representative in the contractor’s labor camps and

the conditions of the toilet facilities at site are in good order and commensurate with the

regards to gender issues



Page 23 of 68

Recommendations

EPC contractor needs to submit environmental monitoring report to Project Owner on a

regular basis (monthly)

Newly legislated and/or revised environmental laws shall be examined carefully in order

to determine whether they are required to be implemented during the project execution

Contractor needs to comply with the EIA and the requirements specified in chapter VI of

the ADB environmental assessment guidelines, 2003.

Contractor needs to comply with all relevant local regulations to the project

Contractor shall once every 6 months organize exercises based on likely site accident

scenarios in which the key site personnel assigned to emergency cases shall show their

capabilities to attend such incidents in their leading roles.

Contractor shall periodically review and evaluate the efficiency of the Project EMP in

their working place

It is recommended to repeat these Audits at regular intervals throughout the project

construction phase as the labor quota will further increase over time

Graphic 1 Results of 6 monitoring times of air quality.

Assessment of the monitoring results:

Through 6 monitoring times during 2 days each in February (two times), March, April, May and

June 2013, the results show that:

The monitoring results for average 1 hr TSP at 2 monitoring points KK1 and KK2 in four

monitoring times (March, April, May and June) are higher than the limited value in

QCVN05:2009/BTNMT – National Technical Regulations on Ambient Air

Quality(higher than 1,09 – 1,93 times). Especially the 22th of March and 13th of June

monitoring times, the monitoring results for average 1 hr TSP at 2 monitoring points KK1

and KK2 are higher than the limited value in QCVN05:2009/BTNMT – National

Technical Regulations on Ambient Air Quality (higher than 1,29 – 1,4 times).

The monitoring results for average 24 hr TSP at 2 monitoring points KK1 and KK2 in all

four monitoring times (point KK1) and three mobilizations (point KK2) are higher than

the limited value in QCVN05:2009/BTNMT – National Technical Regulations on

Ambient Air Quality (higher than 1,135 – 1,71 times). Especially the 22th of March and

13th of June mobilization at monitoring point KK1, the monitoring results for average 24

hr TSP at 01 monitoring point KK1 are higher than the limited value (1,475 times).

The monitoring results for average 24 hr PM10 at monitoring points KK1 and KK2 in all

six monitoring times are approximations and higher than the limited value in

QCVN05:2009/BTNMT – National Technical Regulations on Ambient Air Quality

(higher than 0,975 – 1,48 times).

Comparison of monitoring results between KK1and KK2 shows that KK1 has higher

concentrations of air pollutants than those at KK2, because the population density at KK1

is higher than that at KK2.

The time that concentrations of average 1 hr TSP and average 1 hr PM10 at 2 monitoring

points reach maximum is the rush hour when traffic activities are the highest (17h00 ÷

18h00).

The weather in Mong Duong: During the first 6 monitoring times in 2013 because it`s

mostly sunny and hot ( especially in the four months: March, April, May and June), dry

roads, vehicles transport more, so the monitoring results for average TSP are high and

exceed the limits.

Assessment of Noise monitoring results:



The monitoring results for noise in the daytime of 7h - 8h and 17h - 18h during the period

of 6h - 21h at KK1 are approximate but higher than (about 0,7–2,6 dBA) the limited value

in QCVN 26:2010/BTNMT – National Technical Regulations on Noise; at KK2 are lower

than the limited value in QCVN 26:2010/BTNMT.

The monitoring results for noise in the nighttime of 22h – 23h during the period of 21h-

6h, at KK1, monitored point about 7m from the road are higher than (about 7,1-12,4 dBA)

the limited value in QCVN 26:2010/BTNMT – National Technical Regulations on Noise;

at KK2, monitored point about 20 m from the road, are higher than (about 0,8-4,5 dBA)

the limited value in QCVN 26:2010/BTNMT – National Technical Regulations on Noise.

Caused by transport activities increased on the old 18A road at night, such as: carrying

coal, materials when the weather in Mong Duong is sunny, hot and dry.

At the Working site:



The monitoring results for noise at the working site at all 6 monitoring times, the noise level

monitored in 1 hour at the turbine and boiler area is about 73,4 – 82,1 dB(A). If compared with

the allowable noise level for the working place, then they are lower than the limited value in

TCVN 3985:1999 (85 dB).

Assessment of the Vibration monitoring results:



Monitoring results for vibration level at 2 sites during the period of 6h – 21h are lower

than the limited value in QCVN 27:2011/BTNMT – National Technical Regulations on

Vibration.

Construction activities of Mong Duong 1 Thermal Power Plant are almost entirely

implemented during daytime, therefore no vibration is experienced during nighttime, from

21h-6h

3.1.4 Overall Assessment Air & Noise and Vibration

Implementation of Environmental Management measures by the Construction contractor is

following the guidelines under the EMP

Problems identified:

During the first 6 months in 2013, construction activities at the Site of Mong Duong 1

were considered normal with activities at site taking place such as pile driving, foundation

digging, concrete works for foundations of boiler, turbine and other equipment, building

works, soil conveying with transport vehicles and other executing plant and machinery.

The two monitoring stations KK1 and KK2 located at residential areas selected in the

EMP are not impacted during the construction phase of Mong Duong 1 thermal power

plant, but may be impacted during the operational phase, particularly from the higher

pollution sources (boiler, smoke stack)

Air pollution sources (mainly dust) to the dense residential areas of Mong Duong Ward,

which is near the two sides of the old no.18A road are mainly caused by transport

activities (carrying coal, materials, car, motorcycles…); sorting out coal plant (near KK2),

coal discharge area (especially when the wind blows from south-east direction)

Air pollution (dust and other pollution) is also increasing on the new no.18 road due to

increased transport activities over the 6 months

Comparing monitoring results (dust) between the last 6 months of 2012 and the first 6

months of construction phase in 2013 shows that the first 6 months of 2013 has higher

concentrations of air pollutants than the 6 months before. Especially in the 3 months

(April, May and June) in 2013) when the weather was dry and hot.

The surface freshwater resources in the studied area that will be affected by the Mong Duong

power plant development consists of the lower reaches of the western Mong Duong river which

discharges at the plant site, the lower estuary of the small De Dach rver to the north, and the

distant Thac Thay river to the north of Cam Hai commune. Mong Duong river drains into a small,

sparsely populated basin from the west that is dominated by the active open pit coal mine

activity. The river passes through Mong Duong town just before discharging into Luong Gac

channel at the plant site. The analytical results of the samples are summarized in Table 12

According to the analytical results for collected surface water samples all heavy metals, oils, total

suspended solids, ammonia, chloride, coliform, nitrogen and phosphor are lower than QCVN

08:2008/BTNMT, category B2– Water for Transport and other purposes with the requirements of low water

quality

B. Coastal water quality

The Mong Duong thermal power plant is situated in north western Bai Tu Long in northern

Vietnam. The coastal zone in this area is typical of Vietnam, being dominated by vast sandy

sediment deposits that extend from well above the high water mark to beyond 5km offshore.

Coastal water samples were collected from the following four zones that potentially would be

affected in different ways by the power plant development: (i) Near shore area of Cam Hai

commune; (ii) at the Ash pond; (iii) in the Van Don district (island group) far away about 1km

East of the project site and (vi) Luong Gac channel from Cam Hai commune south to Cua Ong.

At the three points (LG-1; LG-3; LG-4) for impact assessment of transportation activities to

coastal water environment, eight (8) coastal water samples were collected at selected locations.

The locations of coastal water sampling are shown in the Figure 3. The coordinates of coastal

water samples are shown in Table 13

The lower reaches of the river starting at Mong Duong town are brackish and strongly influenced

by the tidal cycle of Luong Gac and Bai Tu Long. The delta at the mouth of the river below

Mong Duong town experiences annual flooding resulting from the combination of high runoff of

the rainy season and spring (full moon) tides. Turbidity and suspended sediment loads in the river

are high, caused by land erosion from human activity (open-pit coal mining) and the natural

sandy soils of the region.

The monitoring and analyzing results of coastal water are presented in Table 14

Recorded Mn concentrations at SW-3b exceed the QCVN standard for other uses. The indicators

of organic pollution of BOD show relatively clean conditions, which are consistent with the

sparsely populated basin. The presence of coliform in coastal water indicates the presence of

nearby Mong Duong town. The presence of oil reflects the observed heavy small-boat traffic in

the river. Heavy metal concentrations meet Vietnamese standards.

C. Underground water quality at Existing wells

Nine (9) groundwater samples from existing wells were collected at Cam Y, Cam Hai,

Van Don, Mong Duong. The locations of underground sampling points at existing wells are

shown in the Figure 3. The coordinates of the groundwater sampling points are shown more

detail in table15

Results of the groundwater sampling as in Table 16 show that:

COD concentration in most sampling points were relatively higher than the reference

standard

Cl- was relatively high in PW-03, PW-04, PW-07, PW-09 with concentration above the

reference standard QCVN09

NH4+ was detected higher than the reference standard at PW-04

Coliform at most stations were measured at levels above the reference standard

D. Underground water quality in water of drilled Wells

The groundwater monitoring locations at the construction site of the MD1-TPP have been

backfilled during the process of ground backfill and leveling. The average backfilled depth from

the well’s bottom to ground surface is now in the range of 11,0 – 35,0 m. These wells have been

constructed and designed for monitoring the ground water quality inside the MD1-TPP’s

boundary following the EIA of ADB.

Eleven underground water samples of drilled wells were collected at the selected locations. The

locations of coastal water sampling are shown in the Figure 3. The coordinates of coastal water

samples are shown in Table 17.

It noted that that during the survey time at the construction site in March, 2013, two of the

underground water wells GW-08 and GW-06 have been filled by sand due to filling internal road

for slag dump area. To solve this problem, the Contractor has drilled new wells but the depth is

only 9m, so the Contractor should be requested to drill new wells to the depth of 22m and 18m as

shown in Table 17.

The monitoring and analyzing results of underground water (Drilled wells) are presented in Table

According to the Monitoring and analyzing results for collected underground water (drilled

wells) samples:

Chloride and coliform was relatively high in GW-05, GW-06, GW-07-D, GW-08, GW-

09; GW-10-D, GW-11, with concentrations above the referenced standard

Cd and Hg were also detected in concentrations above reference standards in GW-10-D

3.2.4 Overall Assessment Water Quality

Through the results of monitoring and analyzing of surface water and groundwater at Mong

Duong 1 thermal power plant project, we have following comments:

At the time of the survey from January to June, 2013, obstacle removal and Mong Duong river

alignment activities were finished and construction activities under implementation

Drilled wells labeled GW-01, GW-02, GW-03, GW-04, GW-05 and GW-08 were covered during

site clearance and building. They are important ground water monitoring points. The

environmental consultant for water quality recommends that investor should drill new wells

which replace the covered wells.

Impact of obstacle remove activities in coastal surface water is monitored by coastal surface

water sampling sites labeled SW-3a, DD-1, SW-06, SW-07, SW-5a, SW-5b, DD-04, SW-08.

Parameters of them are within limit in comparison with QCVN 10: 2008/BTNMT, (others

column)

Impact of Mong Duong river alignment activities in coastal surface water is monitored by coastal

surface water sampling sites labeled SW-01, SW-03b, SW-04. Parameters of them are almost

within limit in comparison with QCVN 08: 2008/BTNMT, (B2 column.)

Impact of transport activities in coastal surface water is monitored by coastal surface water

sampling sites labeled LG-1, LG-3, LG-4. Parameters of them are within limit in comparison

with QCVN 10: 2008/BTNMT, (others column.)

Change of parameter’s concentration through surveys trend to decrease

Two of water pollution sources are water discharge from coal mining via Mong Duong river and

ships transport coal in the waterway. Spilled coal from ships will dilute element and compound to

coastal water (such as: Fe and Mn). So, decreasing trend may be the result of management and

treatment improving of water discharge from coal mining and the improvement of coal smuggle

management in the waterway.

Almost all tested items of underground water at sampling sites are within limit of the National

technical regulation on underground water quality QCVN09/2008/BTNMT except Cd, Cl-

content and content of microorganisms (Coliform).

Concentrations of chloride (Cl-) beyond permissible limits of National technical regulation on

underground water quality QCVN09:2008/BTNMT at the site PW-03, GW-01-D, GW-08, GW-

09 and GW-11. This is explained that sampling sites are located in the coastal and islands areas

thus they may be saline lightly.



Page 49 of 68

Concentration of microorganisms (Coliform) beyond permissible limits of the National technical

regulation on underground water quality QCVN09/2008/BTNMT at the site PW-01, PW-02,

PW-03, PW-04, PW-05, PW-06, PW-08, PW-09. This is explained that water in existing wells

are not usually utilized thus water is not rotated and easy to make condition for microbial

growing.

Following surveys, change of underground water parameters at sampling sites are low and

relative stable.

3.2.5 Recommendation

From the above mentioned results at the monitoring times from January to June 2013, it may be

concluded that the impact of obstacle removal, Mong Duong river alignment and construction

activities to the coastal surface water and underground water is minor.

Contractor should be requested to drill new wells with the depth of 25 - 30m

Maintain the implementation of present measures to minimize environmental pollution.

4. AQUACULTURE & FISHERY

4.1 Overview

During the first half of 2013, the Environment Monitoring and Analyzing Centre (EMAC) of

Quang Ninh province carried out two surveys to monitor the aquaculture and fisheries activities

surrounding the project sites such as Thac Thay, De Dach and Mong Duong river and the coastal

area of Cam Hai. A number of methods to collect data and information were applied to assess the

implementation of the EMP requirements and project EIA through fishing activities and aquatic

resources monitoring. The methods included: fact-finding survey, direct interview, interview

through prepared questionnaire, reference method and statistic and comparison methods. In

addition, several meetings and site visits were conducted to gather the data contained in this

report. During the site visits photographs were taken to serve as proof of compliance or non-

compliance and reference documents were copied or photographs of these were also taken.

4.2 Inspection Activities

The inspection team conducted two surveys on aquatic resources and fisheries and aquaculture

activities in Thac Thay, De Dach and Mong Duong rivers and the coastal area of Cam Hai. The

first survey was done on the 22nd March, 2013 and the second one on 9st May, 2013.

Aquatic resources in term of species composition and abundant were poor in Mong Duong and

De Dach rivers. During the surveys, the inspection team observed some small pelagic fish such as

rabbit fish, mullet in De Dach and Mong Duong river at high tide, however there have not been

any large fish or other aquatic species at Mong Duong river at low tide (see pictures). Thus, there

were no fishing activities in these rivers. In both surveys water quality in these rivers was poor

due to the high turbidity of coal debris and clay in the river water. The Mong Duong stream was

narrow and water depth was very low. Thus, the changing of Mong Duong river at the

construction phase have impacted on the water speed and aquatic resources. It is concluded that

Mong Duong and Thac Thay river are environmentally impacted by of coal mining activities.

There were some fishing activities in the river mouth of De Dach and Mong Duong river.

Fishermen collected bivalves and small fish at mangrove forests. Fishing activities in these areas

are stable in capture production and species composition. That is because these areas are not

major fishing grounds and catching methods are simple. In addition, the construction of Mong

Duong 1 power plant may have little impact on the aquatic resources. Number of fishing boats

anchored at De Dach and Mong Duong river mouths were higher in the first survey than in the

second one. The second survey was in the capture season for fishermen, therefore almost every

fishing boat went to Vandon and Co To island for fishing. In addition, the equipment shipments

to the Mong Duong power plant project may have impact on fishing activities, especially by

anchoring the vessels nearby the project site.

Fishing activities were observed in the Thac Thay river, Luonggac and coastal line of Cam Hai

commune in both surveys. In the first survey, it was observed that fishermen are catching fish,

crustacean and mollusc in the Luonggac area. They use small boats to exploit fish or collect



Page 51 of 68

mollusk and/or small fish at mangrove forests. In the second survey, we did not observe any

fishing activities in the Luong giac area. It is reported that fishermen went offshore for the South

marine fish exploitation season. The species composition and their abundance were naturally

stable during the surveys due to these areas are quite far away from the Mong Duong power

plant. There were no shrimp culture activities at Cam Hai commune due to loss from the shrimp

disease outbreaks and natural disaster (flooding).

4.3 Overall Assessment Aquaculture and Fishery

Based on the results of the two surveys on the fishing and aquaculture activities in Thac Thay, De

dach and Mong Duong river and along the coastal line of Cam Hai commune from January to

June 2013, it is concluded that:

The Construction phase of Mong Duong 1 power plant has minor impact on the aquatic

resources in the inspected areas

There were no fishing activities in De Dach and Mong Duong river due to heavy

industrial pollution from mining and coal trading. Number of aquatic species and their

components in these areas are limited.

Some fishing activities in the Thac Thay river and Luonggac areas were observed, but

there are no shrimp activities in Cam Hai coastal line due to loss from shrimp disease

outbreak and flooding.

5.3 Overall Assessment Mangrove Reforestation

Mangrove quality develops well, branching off well.

The natural and environmental conditions support the mangrove’s development.

With the results above, the Mangrove planting project has met the requirement of the EIA

EPC contractor’s construction workers need to be educated during the course of the

safety and environmental trainings on the need to avoid direct and/or indirect disturbance

of the mangroves.

Prohibit dumping of waste in mangrove and forestry areas

6. OVERALL CONCLUSIONS AND RECOMMENDATIONS

This chapter is providing the Overall Conclusions and Recommendations of the

Owner/Consultant regarding all health & safety and environmental aspects required to be

implemented by the EPC contractor.

6.1 Health, Safety & Waste Disposal Management

Conclusion

This topic covers Health and Social aspects, Site Safety and Security, Site Waste management

and Soil contamination issues

Generally good overall performance of the EPC contractor’s appointed HSE team with

responsible Environmental Officer (OE) in place

Good site safety management of the EPC contractor with regards to fire safety, plant and

equipment safety, labor safety, worker training before entering site, access gate checks

before entering site etc.

Until now No fatality and No Lost Time accident occurred with an accumulated total

man-hours reaching 5’200’000 as of July 2013

Until now no serious soil issues happened at site. Some small oil spillage occurred but

were treated immediately as per the Contractor’s EMS

Waste management follows the contractor’s EMS by separating waste into different

groups and collected and disposed as per the EMS requirements. Until now there is very

little hazardous waste at site such as oil and chemicals, but in time to come there will be

more of these materials to dispose of

All required permits are in place ie. Permit To Work, Confined Space Entry Permits, Gas

Test Certificates etc.

Checklist are submitted regularly to Project Owner for environmental performance

monitoring program done weekly by EPC contractor

First Aid service available 24/7

Monthly report issued to the Department of Labor Quang Ninh province for labor

movements

The health issue of the labor force is one of the topics that requires close monitoring as

part of the health and safety management plan

Current audit results show that both men and women are well informed of potential

health and safety risks: HIV/AIDS control and prevention activities for both camp

workers and offices

Recommendations:

EPC contractor to submit environmental monitoring reports and check lists to Project

Owner on a regular basis (monthly)

Contractor to inform Project Owner immediately of any incidence occurrence at site

whether it is concerning a vehicle accident, labor accident, fire accident, soil

contamination or other incident not further specified here.

EPC contractor to strictly enforce site safety and warn offenders or in repeat cases

dismiss from site (some recent incidents as shown in the attached pictures do not give a

good impression and need to be corrected)

Newly legislated and/or revised environmental laws shall be examined carefully in order

to determine whether they are required to be implemented during the project execution



Page 56 of 68

Contractor to ensure that it complies with the EIA and the requirements specified in

chapter VI of the ADB environmental assessment guidelines, 2003.

Contractor to comply with all relevant local regulations to the project

Contractor shall once every 6 months organize exercises based on likely site scenarios in

which the key site personnel work through their emergency response roles.

Contractor shall periodically review and evaluate the efficiency of the Project EMS in

place

Number of site toilets to be increased as labor force increases

Owner/Consultant to perform regular audits at the contractor’s labor camps especially

with regards to gender issues. (next audit proposed at Licogi’s labor camp)

6.2 Environmental Quality Monitoring

This topic covers Air & Noise and Vibration, Water quality, Aqua culture and Fisheries and


6.2.1 Air & Noise and Vibration Monitoring

Conclusion

Construction activities at the site of Mong Duong 1 increased over time compared to the

last reporting period commensurate with ongoing progress in the first half of 2013.

Therefore construction activities impacted more on the air environment (dust) and noise

to nearby residential areas then in previous months

The two monitoring stations KK1 and KK2 located at residential areas selected in the

EMP are hardly impacted during the construction phase of Mong Duong 1 thermal power

plant, but may show an impact during the operation phase, particularly from the high

pollution sources (boiler, stack etc.).

Comparing the monitoring results (dust) between the last 6 months of 2012 and the first 6

months of construction phase in 2013, it shows that the first 6 months of 2013 has higher

concentrations of air pollutants than the 6 months before, especially in the 3 months

April, May and June 2013 when the weather was dry, sunny and hot. The increase is

mostly due to increased traffic on the new no.18 and old 18A road likewise.

Recommendations:

On the new no.18 road near the entrance of Mong Duong 1 and Mong Duong 2 power

plants, heavy vehicles travel a lot, so the road is very dirty and dusty. The road needs

regular water spraying to improve the conditions, especially in the dry season. The

appearance of construction waste in nearby vacant land (along the new no.18 road such

as concrete from bored piles and other construction debris needs to be removed and kept

neat and tidy at all times.

Noticeable environmental impact during the reporting period has not only been caused by

pile driving activities, foundation digging, construction and soil conveying, but also due

to social environment changes caused by the gathering of the large work force in the

Mong Duong precinct which causes all sort of problems ie. regarding to services, food

provision etc. These and related problems need to be evaluated in addition and mitigated

as much as possible.

6.2.2 Water quality Monitoring

Conclusion

Impact of obstacle removal activities in coastal surface water is monitored by coastal

surface water sampling sites named SW-3a, DD-1, SW-06, SW-07, SW-5a, SW-5b, DD-

04, SW-08. Parameters of them are within limit in comparing with QCVN 10:

2008/BTNMT, (Others column)

Impact of Mong Duong river alignment activities in coastal surface water is monitored by

coastal surface water sampling sites named SW-01, SW-03b, SW-04. Parameters of them

are almost within limit in comparing with QCVN 08: 2008/BTNMT, (B2 column)

Impact of transport activities in coastal surface water is monitored by coastal surface

water sampling sites named LG-1, LG-3, LG-4. Parameters of them are within limit in

comparing with QCVN 10: 2008/BTNMT, (Others column)

Change of parameter’s concentration through surveys trend to decrease

Two of the water pollution sources are water discharged from coal mining via Mong

Duong river and ships transport coal in the waterway. Spilled coal from ships will dilute

elements and compound to coastal waters (such as: Fe and Mn). So, decreasing trend may

be resulted of management and treatment improving of water discharge from coal mining

and the improvement of coal smuggle management in waterway.

Almost all tested items of underground water at the sampling sites are within the limits of

the National technical regulation on underground water quality QCVN09/2008/BTNMT

except Cd, Cl- content and content of microorganisms (Coliform).

Concentrations of chloride (Cl-) beyond permissible limits of the National technical

regulation on underground water quality QCVN09:2008/BTNMT are found at the site

PW-03, GW-01-D, GW-08, GW-09 and GW-11. This is explained by the fact that the

sampling sites are located in the coastal and islands areas, thus they may be saline lightly.

Concentration of microorganisms (Coliform) beyond permissible limits of the National

technical regulation on underground water quality QCVN09/2008/BTNMT are found at

the site PW-01, PW-02, PW-03, PW-04, PW-05, PW-06, PW-08, PW-09. This is

explained by the fact that water in existing wells are not usually utilized thus the water is

not rotated and easy to make condition for microbial growing.

Following surveys, change of underground water parameters at sampling sites are low

and relative stableness.

Recommendations

Contractor should drill two additional wells with a depth of 25 -30m to compensate for

the two that are now covered after the land backfill activity

Maintain implementation of all current measures to minimize environmental pollution of

all surface and underground water resources.

6.2.3 Aquaculture and Fishery Monitoring

Conclusion

Based on the results of the two surveys on fishing and aquaculture activities in Thac Thay, De

Dach and Mong Duong rivers and along the coastal line of Cam Hai commune during the first

half of 2013, it may be concluded that:

The construction phase of Mong Duong 1 power plant has minor impacts on the aquatic

resources in the inspected areas.



Page 58 of 68

There were no fishing activities in De Dach and Mong Duong rivers due to heavy

industrial pollution from mining and coal trading. Number of aquatic species and their

components in these areas are very limited.

Some fishing activities in the Thac Thay river and Luong Gac areas were observed but

there are no shrimp activities along Cam Hai coastal line due to loss from shrimp diseases

outbreak and flooding.

Normal fishing activities and aquaculture are observed in the Thac Thay river and along

the coastal line of Cam Hai commune.

Recommendations

Contractor to strictly enforce his solid waste and waste water disposal management plan

and do not permit dumping of any hazardous substances into nearby rivers or sea.

6.2.4 Mangrove Reforestation Monitoring

Conclusion

Mangrove quality develops well, branching off well.

In the allocated area of 52 ha of mangrove forest which was replanted, there is 95%

survival rate of plants

The survey and inspection results of the mangrove reforestation shows that the mangrove

is developing well under the present environmental conditions at the project areas..

The advantage natural and environmental condition support for mangrove’s development.

With the current results, the Mangrove planting project has met the requirement of

ADB’s EIA

Recommendations

Keep protecting and feeding the mangrove to ensure of their good development and

branching off.

Continue with maintenance activities such as tree clearing, weeding and replanting of

failed areas (Using local labors for replanting and protecting mangrove area)

Educate construction workers on the need to avoid direct and indirect disturbance of the

mangroves

Prohibit dumping of waste in mangrove and forestry areas and resource extraction from

mangroves and plantation forestry areas.

Treat the mangrove forest in Dong Rui and Tien Yen as a special use forest, as this needs

4 years taking care (tree clearing, weeding , replanting of failed areas) and protecting.
