4.1. Environmental effects monitoring

4.1.1. Current velocity

15. Following the EMoP, current velocity at Luong Gac in vicinity of cooling water discharge (2-3

stations) should be monitoring by automatic current meters continuously for two weeks in dry season and two

weeks in wet season in first year of plant operation.

16. The monitoring of current velocity was conducted at 3 locations (LG-1, LG-2 and LG-3 in Table 2,

Figure 1, Figure 2) for four times in June and July 2017, but not continuously for two weeks. The result is

summarized in Table 3.

4.1.2. Ash pond leachate

17. Following the EMoP, heavy metals of ash pond leachate should be monitored semi-annually,

however, there is no leachate discharged because the water from the ash pond is circulated in a closed system.

Based on ambient groundwater quality monitoring result in item 4.1.4, it was shown that quality of

groundwater surrounding the Plant and the Ash Pond is under permitted limit in comparison with the Code

QCVN 09-MT:2015/BTNMT – National Technical Regulation on groundwater quality. Therefore, PMB1

assumes that there is no leak of water from the Ash Pond to ambient environment.

4.1.3. Ambient surface water quality

18. Following the EMoP, ambient surface quality (T oC, TSS, DO, N, P, heavy metals (As, Cr, Cd, Cu,

Pb, Zn, Ni, Hg, Fe, Mn, Se), oil and grease) should be monitoring at several locations annually.

a) Water quality at Ash pond

19. In 2017, water samples were taken at 3 points in the ash pond (AP-2, AP-3, AP-4 in Table 4, Figure

1, Figure 2) for one time on 15 June 2017 and analysed. The result is summarized in Table 5. All the

parameters are within the Vietnam Standard Code QCVN 40: 2011/BTNMT for National Technical

Regulation on Industrial Waste Water2.

4.1.4. Ambient groundwater

22. Following the EMoP, ambient groundwater quality (heavy metals (As, Cr, Cd, Cu, Pb, Zn, Ni, Hg, Fe,

Mn, Se), VOC, SVOC, TPH, E.coli and coliforms) should be monitoring at 20 points including 9 pumping

wells (PW-01 to PW-09) annually.

23. In 2017, water samples were taken at 8 points (PW02, PW04, PW07, PW08, PW09, GW01D, GW02,

GW05 in Table 9, Figure 1, Figure 2) for one time on 15 June 2017 and analysed. The result is summarized in

Table 11. All the parameters except for Coliform are within the Vietnam Standard Code QCVN 09-

MT:2015/BTNMT – National Technical Regulation on groundwater quality. It is assumed that the coliform

level exceeds the standard because the wells are no longer used (therefore no cleaning has been done for a long



9

time).

4.1.10. Fishery and aquaculture activity and catch – species, productivity

28. Following the EMoP, fisher and aquaculture activity and catch – species, productivity should be

monitored through interviews with sample of households at Mong Dong River, Cam Hai, De Dach River, and

Thac Thay River, quarterly for the first two years and biannually thereafter. A map of rivers (Figure 4), a map

of surface freshwater resources in the Project Area (Figure 5), and a map of sampling stations for

oceanographic studies (Figure 6) are in the next page.

29. In 2017, EMAC of Quang Ninh Province conducted investigation and took a census of fishing

activities and catching of aquaculture species at Thac Thay River, De Dach River, Mong Dong River and other

coastal areas of Cam Hai (which are on EMAC’s regular investigation route) on 19 June 2017. At this time,

quite numerous number of ships and boats were at Van Don bridge and it was easily recognized that these

boats had just finished cuttlefish night fishing because the boats loaded many kinds of lights and cuttlefish

fishing tools.

30. The investigation result showed that number of aquaculture households remain unchanged since

before the MD1 was constructed and there is no household who implement aquaculture activity in cage and

raft. There is only one household – Mr. Nguyen Van Thanh – who has around 8.5 hectare of aquaculture

activities, and this area is nearby MD1. His aquaculture system is quite modern, the whole system is embanked

by planted coconut trees to strengthen the embankment against the sea wave attack. Based on an interview, he

is raising shrimp and there have been no epidemic diseases, so the productivity has been remaining stable.

Quality of coastal water is qualified for aquaculture activities. At monitoring time, there were few local people



12

who go fishing, instead there are some households who is spreading net along the river.

Figure 6. Map of Sampling Stations for Oceanographic Studies

31. Detailed investigation results of respective area are shown as below:

32. De Dach River: Starting at high mountain area of Mong Duong ward, the main section of the river is

located in the northern area of National Highway No. 18. Final section (about 3.4 km) of the river has been

used as the discharge canal of Mong Duong Power Complex. Before reaching MD1, the river goes through

many residential areas of Mong Duong and influenced by domestic waste water as well as waste water from

coal exploitation activities at the upstream area. The downstream area is also influenced by processing and

trading/exporting activities at coal ports of Duc Trung Company and Duc Ngoc Company. All these activities

caused heavy sedimentation of De Dach River and its bed is dried up during dry seasons. Moreover, the river

water is usually edulcorated when the tide is down and salinized when the tide is up. With the above

conditions, there is no aquaculture activities at De Dach River area. Other catching activities could be observed

little only during rainy seasons.3

33. Mong Duong River is the longest river in the area. About 1.2 km of Mong Duong River at estuary

section was diverted in 2010 for the construction of Mong Duong thermal power complex (MD1 and MD2).

The original river path was backfilled, and bed of the diverted river was dredged as part of Mong Duong

thermal power complex construction. During the field survey on 19 June 2017, valuable fish were no longer

observed, but very low economic and scientific value fish (such as bee fish, halfbeaks, golden rabbit fish) were

found at the mouth of the river. No aquaculture activities were observed at river’s estuary and the section

between mouth and Mong Duong town, although some fish cages were found at the mouth of the river. 4 It is

assumed this is mainly attributed to the water pollution caused in the upstream which is dominated by pit coal

mine activities of Khe Cham and Mong Duong coal exploitation companies. The river also passes through

centre crowded area of Mong Duong town, and becomes the main discharge canal of domestic waste water and

solid waste (at some locations) in the downstream. As recorded from a local newspaper (Quang Ninh News)

in June 20125, the river was heavily contaminated by the excavated soil from coal mining activities and

3 According to MD1’s EIA prepared in 2006, 12,150 kg of 20 fish species (equivalent to USD 44,448 fisher revenue) were

caught and 6,200 kg of 6 vertebrate and invertebrate species (equivalent to USD 22,852 fisher revenue) were cultured and

harvested in De Dach Estuary every year. 4 According to MD1’s EIA prepared in 2006, 4,500 kg of 20 fish species (equivalent to USD 17,085 fisher revenue) were caught

and 12,500 kg of 4 vertebrate and invertebrate species (equivalent to USD 66,220 fisher revenue) were cultured and harvested

in Lower Mong Duong River every year. 5 http://www.baoquangninh.com.vn/xa-hoi/201206/song-mong-duong-song-chung-ai-khoc-2170352/

domestic wastewater discharged by local people. The lower reaches of the river starting at Mong Duong town

are brackish and strongly influenced by the tidal cycle.

34. Thac Thay River is located quite distantly from coal ports such as Khe Day port, Cam Y port. Water

quality of this area is in good condition, and some small-scale aquaculture pools and some households who do

fishing were found.

35. At Thac Thay River area and outfall, aquaculture benefit remains at average level; in details there are

around 58 households who do fishing, among which 20 households do coastal fishing, 15 households do

aquaculture activities, 04 households raise aquaculture by cage. For the households who raise fish by industrial

method during autumn and summer season: there are still households who raise fish by cage and raft but not so

many, other catching activities are still in normal, but the quantity is little.

+ There are some catched fisheds such as Spaus latus, Epinephelus akaara, Mugil cephalus Linnaeus,

Epinephelinae, Notopterus notopterus Pallas, Sepiidae.

+ Bivalvia, shellfish: Andara granosa, Anadara subcrenata, clam, Austriella corrugate, B. Chinensis

+ Some kinds of shrimp, crabs, snow crab.

36. The condition at coastal area of Cam Hai sea is quite good for fishing and catching and aquaculture

activities. In this area, there are some mangrove plants; this is resident location of some aquaculture species

which can bring benefits to local people and authority.

37. At Luong Gac area, there are some households who often do catching activities, mainly use net and

trap to catch fishes and shrimps.

38. Via investigation, we concluded some results as below:

+ For natural fishes: species are diversible and stable in quantity, some fish, such as Spaus latus,

Epinephelus akaara, Mugil Cephalus Linnaeus, Epinephelinae, cuttle shrimp, Arcidae, Cirripedia, can

bring benefits to local fisherman. However, compared with 1990s, the quantity of species has been

reduced due to influence of surrounding environment and especially destruction catching method by

local fisherman. With catching tools from China such as Cha By, it can allow catching and destroy

aquaculture network, for a long time it can make bad influence to living environment of other species.

Up to now, the households who caught numerous number of aquaculture do not catch at this area

because of low productivity, so it does not satisfy their living standard.

4.1.11. Condition of Mangrove Plantation

39. TPMB1 was required to offset affected mangrove areas. TPMB1 signed contact with Natural

Resource Investment and Development Company to replant 52 ha of affected mangrove area. The mangrove

replantation activity was implemented from 2009 to 2013 in Dong Rui commune, Tien Yen district, Quang

Ninh province. The mangrove plantation was completed and on 10 December 2015 TPPMU 1 and Dong Rui

commune signed an agreement to handover 52 ha of mangrove rehabilitation areas to the commune for

managing. TPMB1 visited mangrove area several times after handing over to Dong Dui commune and ensured

that mangrove trees are well grown up. The latest visit was conducted on 9 February 2018, and it was

confirmed that mangrove trees are still developing well. The below pictures show the mangrove status which

was observed during the last visit.

4.2. Project performance monitoring

4.2.1. Emissions Stack Air Quality

40. Following the EMoP, SO2, TSP, PM10, NO2, CO levels in emission stack should be monitored

continuously.

41. An online monitoring system was installed at 4 stack emission locations (Table 16) for monitoring

parameters such as TSP; SO2; NO2…; the system has been transferring the data to Quang Ninh DoNRE for

their monitoring. However, the system for Stack 2A (Unit 1) broke down in 2016 and was replaced in October

2017. The data of the period from the beginning of the operation (October 2015) until October 2017 was lost

and cannot be restored.

42. When the online monitoring system was replaced in October 2017, TPMB1 started monitoring O2

instead of CO, following the Circular No. 31/2016/TT-BTNM dated 14 October 2016 of MoNRE on

environmental protection of industrial clusters, business and service centers, craft villages and production,

business and service establishments, which requires continuous monitoring of the volume, TSP, temperature,

SO2, NOx, and O2 of air emission from thermal power plants and the results’ transfer to provincial DoNRE.

- The parameters are monitored at Elevation 80m of the Plant Chimney.

43. The summary of the online monitoring result is in Table 17 and Table 18 for Unit 2 (for Stack 2A and

Stack 2B respectively) and in Table 19 and Table 20 for Unit 1 (for Stack 1A and Stack 1B respectively).

44. During the monitoring period between January and December 2017, the emission’s quality (SO2 and

TSP) exceeded Vietnamese Standard (permitted code QCVN 22:2009/BTNMT for National Technical

Regulation on Emission of Thermal Power industry) for several times. All these cases happened when the

boilers started up their operation. The exceedance of the standard was predictable therefore TPMB1 sent a

report to Quang Ninh Provincial People’s Committee, Cam Pha District People’s Committee, Mong Duong

Commune People’s Committee, and Quang Ninh DoNRE, Quang Ning Department of Public Security in

advance of the ignition at each time. This happened for three times for Unit 1 (on 19 March, 26 July and 21

August) and two times for Unit 2 (on 27 January and 12 December). To avoid the exceedance of emission’s

standard and to reduce damage on emission gas treatment system, TPMB1 is planning to change the starting-

up fuel from fuel oil (FO) to diesel oil (DO) by October 2018.

4.2.2. Treated Wastewater Quality

46. Following the EMoP, the quality of treated wastewater (BOD, COD, E.coli, coliform, heavy metals,

TSS, Fe3+

, pH and other parameters required by Decree 67/2003/Nd-CP) should be monitored. COD and pH

should be monitored continuously, while BOD, E. coli/coliform, and TSS should be monitored monthly for the

first year of operation and quarterly thereafter, if monitoring shows proven performance of treatment plant.

47. An online monitoring system at wastewater discharge location for monitoring parameters (such as pH;

temperature; extra Chlorine and waste water flow) was installed, and has been transferring data to Quang Ninh

DoNRE for their monitoring.

48. The summary of the online monitoring result is in Table 22, although MD1 faced with technical

issues which could not extract data of temperature and residual Chlorine from system.

49. If the system detects pH out of the range between 6 and 8.5 (while the Vietnamese standard is

between 5.5 and 9), the outlet of the wastewater treatment plant will be automatically closed, and chemical will

be added to the plant to adjust the pH level to ensure the compliance of the environmental standard. The outlet

will be reopened only after the pH level is adjusted. This case happened 4 times in 2017.

Table 22. Online Waste Water Monitoring Result

50. If the chlorine level goes beyond the Vietnamese standard (1.8 mg/l), the system gives an alarm so

that the staff can take an action to ensure the compliance of the Vietnamese standard (dilute the wastewater

with seawater before discharging). This case has not happened so far. Other parameters such as COD, BOD,

and turbidity are monitored every day to assure that wastewater discharged to outside will be under permitted

limit as per the code QCVN 40:2011/BTNMT of MONRE for national technical regulation on industrial

wastewater.

51. The summary of the daily monitoring result is in Table 23. In 2017, COD, BOD are under the

permitted code QCVN 40:2011/BTNMT. There is no applicable standard of Turbidity.

4.2.4. Discharged Cooling Water’s Quality (chlorine levels and temperature)

56. Following the EMoP, Chlorine levels and the temperature of discharged cooling water should be

monitored at a cooling discharge point weekly, on schedule of varying times and days. At the cooling water

discharge point, MD1 has installed the extra chlorine and temperature meter. At present, all points are online

connected and can transfer data to Quang Ninh DoNRE for their monitoring, inspection and supervision.

Between January and December 2017, the range of the chlorine level is below 0.5 mg/l, and always controlled

far under 2.0 mg/l (QCVN 40:2011/BTNMT).

57. The temperature of surface water (at the inlet of the cooling water) was measured only for 3 times in

2017. According to the 2016 data of the Center for Environmental Monitoring, the temperature of the cooling

water at two locations (inlet of the cooling water/sea water, end of discharge channel) is as follows:

+ On 16/02/2017:

Temperature of the inlet of the cooling water: 21.3oC

Temperature of the end of discharge channel: 21.4oC

Difference: 0.1oC

+ On 14/6/2017:



Difference: 0.0oC

+ On 11/9/2017:



Difference: 0.2oC

+ On 5/12/2017:



Difference: 1.2oC

58. Based on these data, at least on those three days when the temperature of surface water was measured,

the difference of the input cooling water temperature and the output discharge water temperature is not more

than 3oC in difference, which matches with EIA requirements.

4.2.5. Condition of storm water outfall

59. Following the EMoP, the storm water outfall should be monitored by observation monthly. Via

inspection and supervision through storm and typhoon, plan of MD1 has not been flooded, so no damage

occurred for equipment system and human during the monitoring period

4.2.6. Condition of oil separators

60. Following the EMoP, the condition of oil separators in the periphery of MD1 should be monitored by

observation monthly. Condition of oil separators have been checked weekly and no problems have been

identified and it has been in the good condition. During operation stage, at the locations which are easy for oil

spilling, MD1 has designed and installed spillway. After that re-collected oil will be pumped up to oil-mixing

wastewater treatment system. There have been no oil spilling cases during the monitoring period.

4.2.7. Quantity and type of aquatic biota captured at intake screen

61. Following the EMoP, the quantity and type of aquatic biota captured at intake screen should be

monitored by observation and weighing during the screen cleaning. During operation stage up to now; at the

cooling water intake screen, only small quantity (about a few kilograms per week) of aquatic biotas such as:

shrimp and squid have been captured; after that, these aquatic biotas were gathered and treated as domestic

waste by Tuan Dat Environmental One Member Limited Company.

4.2.8. Ash volumes deposited and reused

62. Following the EMoP, ash volume deposited and reused should be measured monthly for the first year

and biannually thereafter. By the end of 2017, 2,104,810 tons of ash was discharged since MD1 came into

operation in October 2015 (for Unit 1) and December 2015 (for Unit 2). In 2017, 279,151 tons of bottom ash



24

and 533,292 tons of fly ash was disposed. 100 % of bottom ash was sold to Dong Bac Infrastructure

Development Company and reused for cement manufacture, while all of fly ash was disposed in Ash Pond

which is located in the premise of MD1. The monthly volumes of deposited/reused ash are shown in Table 26.

63. The capacity of Ash Pond 1 is 2,250,000 m3 (3,260,000 tons) and it was filled by 65 % as of 31

December 2017. As of 26 February 2018, 1,661,181 m3 of ash has been disposed at Ash Pond 1, therefore the

remaining capacity is 588,819 m3, which will serve for only 9 more months. This means that the Ash Pond 1

will be full by January 2019.

64. TPMB1 plans to construct a second Ash Pond (Ash Pond 2) at Ha Chanh village, Cong Hoa

commune, which can be used for four years. The detail planning was submitted to Quang Ninh Provincial

People’s Committee for approval on 9 March 2018 and is expected to be approved by 15 June 2018. After

preparation and approval of (i) investment project document, (ii) environmental impact assessment report, and

(iii) resettlement plan, the construction of Ash Pond is expected to start on 15 August 2019 and completed by

15 December 2020.

65. For proper operation of MD1 and sustainable ash disposal in the upcoming years, TPMB1 is planning

to use ash for the ground levelling of some areas (about 30 km away from MD1). Nowadays, the big amount of

ash discharged from thermal power plant became a problem in Vietnam, and Ministry of Construction has

submitted Technical Guidance for use of ash from coal thermal power plant for construction material (the

Technical Guidance) to the Prime Minister for his approval (expected in Q2 2018). Once the Technical

Guidance is approved, TPMB1 will prepare detail plan of the ash use, which will be submitted to GENCO 3

for approval. Once the plan is approved, both (i) the ash disposed in Ash pond 1 (about 1,600,000 tons) and (ii)

fly ash which will be generated in 2018 and 2019 (about 1,350,000 tons) will be transported by authorised

firms to other areas for ground levelling purpose. This solution could help to avoid disposal fly ash in Ash

Pond 1 over two years and increase capacity for Ash Pond 1 to be filled up to 3.5 years. Therefore, it means

that Ash Pond 1 can be used for 5.5 years.

4.2.9. Breaches of security at ash disposal areas

66. To prevent environmental pollution caused by ash pond leachate, MD1 has one deposit water re-

circulation system returning from ash pond for discharging ash. The water will be treated with neutralized

chemicals prior to returning. Therefore, this system’s water will be operated in the closed circulation manner,

and not discharged to the outside.

67. Following the EMoP, breaches of security at ash disposal site should be monitored by observation at

ash pond monthly. TPMB1 always arranges security 24/24 hours, and closely coordinate with local police so

as to control and assure safety and security around MD1. Therefore, from MD1 entered commercial operation,

there are no safety and security violation at the ash disposal area.

4.2.10. Dumping of waste outside project site or in rivers and Luong Gac

68. During operation stage of MD1, there are no waste dumping to outside of the project site and in rivers



25

and Luong Gac. MD1 always arrange classified waste bins at all operational locations of the plant,

concurrently require operators to collect and classify waste to the specified waste bins. Collected waste has

been transported for treatment by Thuan Thanh Environmental Joint Stock Company (an environmental

company that TPMB1 hired). Thuan Thanh Environmental Joint Stock Company was granted Business

License for Hazardous Waste Management No. 1234.036.VX (05th times) on 28 September 2015 by MONRE.

Hazardous waste discharged during the operation stage includes: waste cloth contaminated by oil, waste oil,

grease, asbestos from insulation material, light bulb etc. For normal solid waste: TPMB1 has signed the

contract No. 30 / HDKT-NDMD-MTTĐ with Tuan Dat Environmental One Member Limited Company for

moving and handling from 4/1/2016 to 4/1/2018. Tuan Dat Environmental One-Member Limited Company is

licensed by the Department of Planning and Investment of Quang Ninh Province with the first registed No.

5701445969 on 6/12/2010.

69. Mong Duong Thermal Power Company always highly concentrates on general site condition and

cleanliness so as to assure clean and green landscape.

4.2.11. Covering of trucks

70. At present, Mong Duong Thermal Power Company sells bottom ash to outside companies; to protect

surrounding environment, Mong Duong Thermal Power Company always supervise and require the buyer to

comply with environmental protection rules; and overload transportation is not allowed to avoid dust polluting

outside environment.

71. Via observation and supervision, the ash on the trucks for transportation is covered, and there is no

dust generated outside, so it means that environment inside and outside is clean.

4.2.12. Environmental approvals at source of limestone, fuel oil, chlorine and coal

72. The following licenses were approved at source of limestone, fuel oil, chlorine and coal.

- The License No. 312/GP-UBND of Quang Ninh People's Committee dated 13 February 2014 and

5. Key Environmental Issues

5.1. Key Issues Identified

79. TPMB1 has always complied with environmental requirements specified by Vietnam Government.

During operational period, there are no incidences or accidents occurred. Environmental issues are complied

with applicable laws and standards of Vietnam Government. In 2017, TBMP1 conduct several additional

environmental monitoring as per EMoP of ADB. In general, all monitored environmental quality parameter

were within the regulated value stated in the relevant technical standards of Viet Nam government.

80. During the monitoring period, the emission’s quality (SO2 and TSP) exceeded Vietnamese Standard



28

for several times. All these cases happened when the boilers started up their operation. The exceedance of the

standard was predictable therefore TPMB1 sent a report to Quang Ninh Provincial People’s Committee, Cam

Pha District People’s Committee, Mong Duong Commune People’s Committee, and Quang Ninh DoNRE,

Quang Ning Department of Public Security in advance of the ignition at each time. To avoid the exceedance of

emission’s standard and to reduce damage on emission gas treatment system, TPMB1 is planning to change

the starting-up fuel from fuel oil (FO) to diesel oil (DO) by October 2018. (para 44)

81. There is no longer fishery and aquaculture activities in Mon Duong River and De Dach River,

however TPMB1 considers this is due to external factors (water pollution caused by coal mine activities and

local people’s waste water in the upstream). (paras 32, 33)

82. Ash Pond 1 is expected to be full by January 2019, therefore TPMB1 is considering some plans for

proper operation of MD1 and sustainable ash disposal in the upcoming years (paras 63, 64, 65).

5.2. Issues from previous report

83. Many environmental quality parameters were not monitored as per requirements during 2016. Thus,

TPPMU1 signed contract with Quang Ninh EMAC for conduct environmental monitoring for several missed

indicators, which are included in the EMoP of the project.

6. Complaints

84. From PAC to date, there is no any complain of resident who live around the plant about environment

of the plant, TPMB1 arrange monthly for resident to go into MD1 to visit and introduce environment treatment

system. After each visit, representative of the residents always highly evaluates environment protection of the

plant.

7. Conclusion and Recommendation

85. In 2017, TBMP1 conducted environmental monitoring tasks as requested in the EMoP of the EIA.

Apart from environmental monitoring as per the requirement of EMoP, TPMB1 also conducted monitoring

activities as per granted environmental Licenses by Vietnam Government. It demonstrates that TPMB1 pays

attention to environmental protection issue in the project area.
