10. Up to December, Volume of unsuitable material of the project dumped in to disposal area

summary is as follows:

P a g e 6

Table 1-4. The total amount of generating solid waste (Soil and rock)

The excessed volume of soil excavated in comparison with the capacity of disposal area of

Lot 10.3 is 278.683,59 – 270.521,04 = 8.162,55 m3, this volume of soil excavated was used for

alley embankment at Km150+100 in according to residents’ request

11. In the Table 1-4: Only disposal area of Lot 10.3 is not enough capacity to dump

unsuitable materials..

12. Quantity of waste soils and rocks and unsuitable grading materials mainly arises from the

project’s activities such as bypasses construction, bridge construction and other items.

13. Although DRCs tried their best to solve resettlement to hand over to contractors, there

is a delay in compensation and handover by DRCs. In Quan Son, 0.3km of road (belonging to

Lot10.2, 11.1 and 11.3) has not fully handed over to the contractors yet. The counterpart fund

for removal of public utilities has not been fully supplied , so remaining issues related to public

works have not resolved yet.

14. PMU1 and District Resettlement Committees (Ba Thuoc and Quan Son) worked

together and agreed with the resettlement schedule, and handed over to the contractor to ensure

no delay in construction works will happen.

2. Incorporation of Environmental Requirements into Project Contractual

Arrangements

15. According to item Sub-Clause 4.18 in the contract of package 10 and package 11 and

Sub-Clause 63 in the contract of package 12 and package 13 (Protection of the Environment)

4. Summary of Environmental Monitoring

4.1. Compliance Inspections (If relevant)

4.1.1 Summary of Inspections Activities

The environmental consultant frequently checked on site:

+ Checked are: on the whole of alignment, construction area, streams and rivers near

construction area, material stockpilling area, storage, concrete cast in situ area, batching plant,

quarries, worker’camp, especially in populous area, hospitals, schools.

+ Cheked time: frequently check 15 times/month, suddenly check if there are any information

from residents and local agency, especially environmental specialist of ADB Mission checked

on the whole project on 25th and 26th November 2015. The environmental polices checked on

site from 5th November 2015 to 9th November 2015 and from 04th December 2015 to 10th

December 2015.

+ Cheked contents: The environmental compliance of Contractors according to CEMP and

EMP, especially “DETAILED AGREED ENVIRONMENTAL ACTION PLAN”. The CS

Consultant collected the evaluating ideas of residents and workers, if there are any disatisfied

P a g e 1 2

ideas, CS Consultant will request the Contractors to stop constructing and to handle problems

immediately.

+ The outstanding issue: Worker camps have not cleaned clearly yet, it is hard to find where

the fire extinguishers are; sometimes, workers did not care about labor safety such as: working

without helmet, lack of sign board and reflective paper. Especially, dumping rocks and soils at

unapproved area Km 143+ 500. After being reminded many times by the environmental

consultant, the Contractor complied with regulation.

17. Safeguards monitoring is implemented by both project owner (PMU1), CS Consultant

and contractors. The following diagram shows the safeguards management organization.

the work execution;

- examine and supervise the environment protection methods in favour of the workers on site

and the surrounding environment which are proposed by the Contractor including: anti-dust,

anti-noise, vibration, surface water, waste treatment and site clearing methods.

- The project normally accept feedback information from local authority levels and local

people to remain, requiring the contractor implementation working measure, ensure traffic and

environment sanitaion.

4.1.2 Mitigation Compliance

19. Overall compliance with mitigation implementation requirements could be described in

qualitative terms or be evaluated based on a ranking system.

20. Air quality and water quality is good (2) because the Contractor implemented mainly

minimization measures. However, noise and vibration are fair due to the contractor

implementation mitigations that were partially effective.

4.2. Surface water Monitoring Program

4.2.1 Summary of Monitoring

- Bottle contained sample: clear, make of plastic or glass; cork made by plastic (not linning paper) or glass.

- Sample location: choose the location in the center of flow, take sample in depth of 0.1m from water surface.

- Physical and chemical test sample:

+ Clean bottle in several times by water.

+ Fill the bottle with water. Cap tightly.

- Take sample to test microbiology, BOD, nitrit:

+ Should choose the opaque bottle and cork, drying both bottle and cork.

+ Sterilize tap (used for taking sample) inside and outside; hands of people (who take sample) were sterilized by acohol.

+ Nearly fill the bottle with water (leaving some air). Cap tightly.

+ Preserve at temperature of 0-5oC during bringing sample to laboratoty.

- Sample volume: Depend on the test criteria to calculate the number of sample.

+ Physical and chemical test: 13 criteria: 1 liter of sample water.

+ Microbiological test: 0,5 liter refrigerated samples (no more than 24 hours).

P a g e 1 5

- Preserve sample: Immediately transporting the sample to laboratory to avoid biochemical reactions that lead to the inccorect result.

21. According to IEE and EIA for Environmental Monitoring (construction stage), the

Project will be implemented surface water monitoring. Monitoring frequency once every six

months.

Surface water monitoring for construction stage 3rd is implemented from 8th to 12nd December

2015.

DO is amount of Oxygen dissolves in water that necessary to aquatic breathing. When water

is polluted by organic compound easily decomposed by microbiology, Oxygen dissolves in water

will be reduced; therefore DO value are lower that DO standard. DO was used as parameter to

evaluate level of polluted organic compound of each water resource. At sampling location, high

abilities because of animal or vegetation dead was decomposed in the water upstream, heavy

raining dragged animal and vegetation dead in decomposed process into the river and stream.

24. Although TSS, Oil & grease are higher than Vietnam regulation, these results are lower

than baseline environmental monitoring results that are presented in section.

25. During construction activities will be impacted to environmental surrounding. However,

they are impacted small with surface water environment.

4.3. Ambient Monitoring Program

4.3.1 Summary of Monitoring

At sampling location, carrying out measure the meteorological parameter (temperature,

moisture, wind speed and wind blow) at site. Bumping atmosphere at sampling location in to

the keeping tool is absorption tube with speed bumping from 0,25 to 2,50 lít/minute. With

different atmosphere CO, Sox, HC using separately absorption solution for each type, return

sample and carrying out analyzing in laboratory. Absorption tube contains samples in to the glass

container with button, capacity from 25-30ml. Transportation must be ensured safety for

samples, avoid breaking, mixing; maintain samples in the cold condition during in transportation

process. Sample should be transferred to lab in the soonest time, maintained in a cold dry place

and immediately carried out analyzing . In General, definition of parameters is implemented as

corrective TCVM for each material and analyzed as Standard methods of publisher American

Public Health Association, Washington, DC 20005

26. Frequency monitoring of noise and ambient air quality are implemented six month per

29. Almost parameters are lower than Vietnamese regulation. PMU1 and CS Consultant

requested Contractor to strictly implement the mitigation measures especially sensitive area. T2

was sampling time from 10 am to 12 am when is the period of construction on site and people

exploited bamboos in the nearby forest, as well as a period of active transportation more

5. Key Environmental Issues

5.1 Key Issues Identified

From July to December 2015, there are many happened issues affected environmental

protection, but with the strict supervison of CS Consultant, the Contractors fully applied

measures to minimize negative affections on environment, for example:

- The batching plant of Cuong Thinh Thi Company: was applied airbag technology to collect

dust and constructed two holes to catch sewage in order to prevent wastewater into natural

environment; limited to operate the plant during studying hour of Son Dien School

P a g e 2 0

- Tan Thanh asphalt concrete batching plant of Lot 10.1 is a integrated area to exploit and

crush stone; that is why this plant generate a great amount of dust. The Contractor installed 5

sprinklers at stone crusher zone, each of the sprinklers is 5 meters high to minimize dust, set the

tarpaulin fence 10 meters high and 20 meters width to avoid spreading dust into concrete batching

plant machines, and equipped labor protective equipment for workers.

- The flood on September 2015: caused lanslide areas, mud and soils from mountain falling

to road and construction area, trees fallen across road; this tremendously affect the environment.

The Contractors treated disposal area landslided, supplemented bamboo fence for diposal areas,

reconstruct slope, mobilized personnel and facilities to clean road and construction area,

transported mud and soils into disposal areas, treated died animals to protect environment.

- Bridge construction: the Contractor installed nets to avoid materials falling into the river..

30. Construction activities affected surrounding environment such as surface water due to

dust and noise, TSS and Oil and grease. The contractors implemented environmental mitigation

measure in compliance with contents mentioned in CEMP, IEE, and EIA.

The main construction activities affected the environmental parameters such as: embankment

excavation and backfilling, constructing positive slope; constructing bridges and culverts;

exploiting rock at quarry and operating AC batching plant

31. Traffic controls such as traffic sign, speed hump, etc. shall be installed at intersections

between existing NH217 and other roads in order to ensure safety for road users.

5.2 Excavation and embankment activities are strictly controlled to protect

environment. Action taken

32. Impacts on environment caused by construction activities were solved during

construction progress with supervision of the CS Consultant. Although the contractors were

requested to water, some sections were still dusty. Therefore, the contractors should water

more than two times per day. Watering activity must focus on populated areas and

properly controlled The Contractors were requested to provide workers with personal

protective equipment (PPE) and workers are requested to equip sufficiently PPE before involving

in construction works. Environmental Specialists and Inspectors often reminded workers to meet

requirement of labor safety and environmental sanitation. Some requirements have been

complied by Contractors (please see appendix 1).

33. The Contractors watered at least twice per day, especially at sections such as: Cam Binh

commune, Dong Tam intersection, Thiet Ong and Thiet Ke communes, Trung Ha commune,

Trung Thuong commune, Quan Son town, Son Dien School, Son Dien commune, Na Meo

commune, and others sensitive areas. However, these areas were properly controlled because

much water would result to muddy areas and affect local people.

34. From June to December 2015, some disposal areas were compacted and properly graded.

Other disposal area will be continuously requested to compact, grass and recover before

completing the project.

P a g e 2 1

35. According to requirement of ADB Mission in November, 2015, the meeting between

CS Consultant, PMU1, Contractor and Son Dien officer was held and a memorandum of

understanding after that meeting was made and submitted in the monthly report on environment

in December, 2015. Lot 11.1 (Cuong Thinh Thi Company) will update operation schedule of

concrete mixing plant and submit to Son Dien School’s officials and the CS Consultant to control

environmental mitigation measures. At AC batching plant of Lot 10.1: the Contractor installed

5 sprinklers 5m hight at crushed stone area to minimize dust, installed tarpaulin 10m hight and

20m width to avoid spreading dust into plant. In addition, frequently spraying water for entrance

of plant; the stone crushers were controlled by workers thanks to electric box from outside, so

cannot be affected by dust and noise

36. HIV/AIDS/TSD awareness and prevention program will be continuously implemented

in line with social plans under the Project

5.3 Agreed Environmental Action Plan during ADB Mission in March and November,

2015 were complied by Contractors. Please, see Appendix 4 for more details. Additional Action

Required

37. The contractors are required to implement all mitigation measures in accordance with

CEMP under PMU1 and the CS Consultant’s strengthened supervision. PMU1 and the CS

Consultant continuously supervised contractors’ implementation according to Agreed

Environmental Action Plan in November, 2015. The compliance of contractors will be updated

and submitted to ADB.

6. Conclusion

38. PMU1 and the CS Consultant cooperated with local authority of all levels to strictly

control implementation of mitigation measures on site.

39. Slope protection at completed disposal sites should be further improved. Protective

barriers at the base of slopes should be further strengthened and vegetation should be planted

immediately..

40. Worker’s camps were not cleaned due to poor awareness of workers. The Consultant

frequently checked worker’s camps, requested the Contractors to keep sanitation, pointed out the

factors affected worker’s health directly, raise awareness of the general hygiene for the

community. In reality, the CS Cosultant always instruct new workers because the Contractors

often have the change of worker. If the Contractor does not sanitate worker;s camps, CS

Consultant will issue the warning letter to stop payment until cleaning camps clearly. Many

workers in all packages have inadequate or inappropriate personal protective equipment (PPE).

Contractors must provide workers with complete PPE to reduce negative impacts on them.

41. Storage and handling of hazardous materials at worker’s camp: (i) arranging areas of oil

storage: poured concrete at the bottom, constructed margin with 10cm in height, and covers;

catch holes; (ii) camp areas have diagram of fire fighting and prevention, accident chart, site

regulation, hotline number; (iii) fire extinguisher, medicine cabinet; (iv) repair worker’s camp.

42. During construction activities, the contractors continuously implemented

compaction for disposal areas up to complete project.

43. In December, the project monitored ambient and surface water. The

environmental monitoring results are shown in Appendix 2.

44. The projectreceives feedback information from local authority at all levels and

local people to make the Contractors ensure traffic and labor safety and environmental

sanitation.On 5th December 2015, the Resident who is living at KM146+800 gave a

feedback: there is a truck dumping soil into bamboo area, this action made soil strewn on

pavement and trigger the unhygienic environment. The CS Consultant checked on site

and found that the Resident hired dumping truck to grade land for building house, this

was informed to District's authority to solve. On 12th October 2015, at Km154+200,

residents gave feedback that there are so many dusts when travelling over this location,

the Consutant checked on site and requested the Contractor to clean soil on pavement,

spray water frequently as well as arrange speed limited sign board.

45. Construction activities cause impacts on environment at high or low level. The

contractors will ensure not to damage to environment. In case of causing damage to the

environment, the Contractors will coordinate with the CS Consultant to overcome.
