Executive Summary

This Environmental Monitoring is conducted based on ADB safeguard’s policy, the laws and

policies of Bangladesh Govt and Loan covenants between ADB and Bangladesh Govt. For

environmental monitoring, variables and indicators are selected interms of project

description, activities during project implementation, probable impacted indicators of physical

and biological environment.

This is the 3rd phase of environmental monitoring commenced (January 2018 to June 2018)

through monthly field visit by the consulatant. In this stage, there are twenty one (21)

substations whereas the constructions work is ongoing and this study cover all these

substations. The monitoring team visited and observe all construction activites and consulted

with relevant stakeholders according to the prepared checklist on physical (i.e. air quality,

waste management, noise and soil quality), ecosystem and biodiversity (i.e. terristrial

vegetation, flora and fauna) status at the construction sites applying both qualitative and

quantitative approaches.

Based on the selected parameters of air quality, the results of the air quality were checked

whether it is satisfactory or not regarding the national air quality standard. Besides, how this

construction activities are related with the air quality has been observed through regular field

visit.

The noise levels were measured during day time at different project sites. Noise showed the

minimum level at the entrance. On the contrary, the noise reading near the construction

zone was un-steady due to different construction activities. The impact of this noise level is

considered as insignificant as it is more like temporary. The provision of soild waste is

maintaining by the EPC contractor as the risks for solid waste disposal is in satisfactory

condition.

The concentration of PM10, PM2.5 and SPM of DESCO project area is higher than the

Bangladesh standard limit. From the above data, we have found data the amount of PM10,

PM2.5 and SPM are maximum which are 227, 128 and 287 µg/m3 accordingly. On the other

hand, concentration of SO2, NOx and CO have found within the Bangladesh standard limit.

The air pollution levels have been compared with the Bangladesh Ambient Air Quality

Standard as adopted in 2005.

During field visit, no significant internal and external sources of air pollution was observed in

the project sites that would deteriorate air quality. Due to vehicular movements, digging of

the earth and loose earth materials (e.g. soil, sand), some dust particles were observed in

the project area. Heavy construction machineries were used to carry out pile work which

caused scanty amount of SOx and NOx which is negligible.

The compliance status of noise quality and waste management have been addressed

through air quality measurement, field observation and consultation with relevant

stakeholders. However, it is found that due to the construction, there is no significant

negative impact on health of community people, but the labors working for construction can

be impacted for heavy sound produced the pilling works. In this regard, availability and use

of earmuff has been suggested as the Corrective Action Plan (CAP) and shared with PMU

for further improvement.

x

The construction activities were found in various stages at different sites during the visits.

There were no ecological resources in the all the substations, except Uttara section-14 and

Mirpur DOHS. Mirpur DOHS, which was situated, near the ditch, the construction materials

and wastes were being drained into the ditch. This might have some negative impacts on

aquatic life forms and their ecosystems. There is a suggestion to make plan for alternative

drainage to avoid the negative impact on fish habitat near the Mirpur DoHs Substation. Most

of the cases, compliance status achieved significantly but for the non compliance issues

several corrective action plans suggested and shared with implementing agency. The status

of non compliance issues will be addressed in the next phase of environmental monitoring.

1.5 Monitoring Law and Policy Standard

11. The Environment Conservation Rules place construction of power plant into the Red

category. The site clearances based on IEE and Environmental Clearance Certificate have

been obtained from Department of Environment (DoE). As per the Bangladesh Govt. policy

standard, environmental compliance monitoring is one of the important part need to be

initiated following the Environmental compliance monitoring guidelines by DoE and the

agreement between ADB and Bangladesh Govt (based on the ADB loan covenants).

DESCO has taken initiatives to expand its infrastructure of the distribution system through

construction of new lines, installation of new substations and rehabilitation of existing

substation in order to provide new connections to the incoming consumers. In this regard,

during carrying out the EIA study for the proposed twenty four 33/11kV Substations, EMP

was prepared following the national guidelines of Bangladesh and policies of Asian

Development Bank. Now, the purpose of the environmental monitoring is to monitor whether

the construction activities are performed or not considering the EMP prepared in the EIA

stage.

1.5.1 Compliance with National Environmental Laws

12. The environmental legislation of GOB gives importance to reduce the negative

impacts of infrastructure development projects, and give priority for the enhancement of

positive impacts due to the project implementation. It conforms the National Environmental

Policy 1992 based on the Agenda 21 of Rio Conference and subsequent enactments of the

The environmental clearance (valid for 1 year) for the project was obtained from the DoE on 25.06.15. The processing for renewal is ongoing as per the Government rules.

3 sites under this project have been relocated that require Environmental clearance certificate. The completion of EIA for these relocated sites is in under process.

1.5.2 Bangladesh Government Regulation and Compliance Monitoring

13. The Bangladesh Environment Conservation Act of 1995 (ECA, 1995) is the key

legislation in relation to environment protection in Bangladesh. This Act is promulgated for

environment conservation, standards, development, pollution control, and abatement. It has

repealed the Environment Pollution Control Ordinance of 1977. The Act has been amended

in 2000, 2002, 2007 and 2010.

14. The main objectives of the Act are:

Conservation and improvement of the environment; and

Control and mitigation of pollution of the environment.

15. The main strategies of the Act can be summarized as:

Declaration of ecologically critical areas and restriction on the operations and

processes, which can or cannot be carried/initiated in the ecologically critical

areas;

Regulations in respect of vehicles emitting smoke harmful for the environment;

Environmental clearance;

Regulation of the industries and other development activities’ discharge permits;

Promulgation of standards for quality of air, water, noise and soil for different

areas for different purposes;

Promulgation of a standard limit for discharging and emitting waste; and

Formulation and declaration of environmental guidelines.

16. The ECA, 1995 specified that no industrial unit or project shall be established or

undertaken without obtaining Environmental Clearance from Director General in a manner

prescribed by the Rules. The project promoter must obtain Environmental Clearance from

the Director General of Department of Environment (DoE). An appeal procedure does exist

for those promoters who fail to obtain clearance. Failure to comply with any part of this Act

Introduction

8

may result in punishment of imprisonment or fine or both. The DoE executes the Act under

the leadership of the Director General.

17. The Bangladesh Environment Conservation Act (Amendment), 2000 focuses on:

(1) ascertaining responsibility for Compensation in cases of damage to ecosystems, (2)

increased provision of punitive measures both for fines and imprisonment and (3) fixing

authority on cognizance of offences.

18. The Bangladesh Environment Conservation Act (Amendment), 2002 elaborates

on: (1) restriction on polluting automobiles, (2) restriction on the sale and production of

environmentally harmful items like polythene bags, (3) assistance from law enforcement

agencies for environmental actions, (4) break up of punitive measures and (5) authority to try

environmental cases.

19. The Bangladesh Environment Conservation Act (Amendment), 2010 introduces

new rules & restriction on: a) Ensure proper management of hazardous wastes to prevent

environmental pollution and Health Risk, b) No remarked water body cannot be filled

up/changed; in case of national interest; it can be done after getting clearance from the

respective department; and c) Emitter of any activities/incident will be bound to control

emission of environmental pollutants that exceeds the existing emission standards (d)

Government may declare any ecosystem as “Ecologically critical area” if it appears to be

degraded or expected to be degraded and take all precaution measures to protect that

ecosystem. In addition, government shall stop any ongoing activities and will not allow any

new developments in the ecosystem after declaration of “Ecologically Critical Area”.

20. The Bangladesh Environment Conservation Rules, 1997 is the first set of rules,

promulgated under the ECA 95 (so far there have been three amendments to this set of

rules – February and August 2002 and April 2003). The Environment Conservation Rules of

1997 has provided categorization of industries and projects and identified types of

environmental assessments needed against respective categories of industries or projects.

21. Among other things, these rules set (i) the National Environmental Quality Standards

for ambient air, various types of water, industrial effluent, emission, noise, vehicular exhaust

etc., (ii) the requirement for and procedures to obtain environmental clearance, and (iii) the

requirement for IEE and EIA’s according to categories of industrial and other development

interventions.

22. The proposed project, according to the DoE, was under the “Red” category accrding

to the Environmental Conservation Rules, 1997 but recent amendment in 2018 made this

project as orange B category.

23. Noise Pollution (Control) Rules, 2006 gives the authority to all the Union Councils,

Paurasabhas, City Corporations, City Development Authority (i.e. RAJUK, CDA, KDA, RDA

etc.) to mark off the areas under their jurisdiction as silent, residential, mixed, commercial or

industrial. They should also put signs to mark those areas. The act also describes the

approved standard limit of sound in the added schedule 1 and 2. In the schedule 1, silent

area means area up-to a radius of 100 meters around hospitals or educational institutions or

special institutions/ establishments identified/to be identified by the government. In the silent

area, it is prohibited to use any kind of horns of vehicles, audio signals and loudspeakers.

According to this act, daytime is counted from 6am to 9pm whereas nighttime is counted

from 9pm to 6am.

Introduction

24. The Motor Vehicle Ordinance, 1983 stated to impose a penalty of maximum two

hundred taka for those vehicles that are emitting smokes that poses health hazard in the

public places. It also restricts the passenger from smoking in public service vehicles and in

any other vehicles with notice of not smoking. This ordinance is enforced occasionally but a

regular enforcement would be helpful to reduce air pollution in big cities including Dhaka.

However, it is to be noted that amount of the penalty is very low which may be revised as

well.

25. The Environment Court Act, 2000 provides for the establishment of environment

courts and matters incidental thereto. This act also provides the jurisdictions of environment

court, penalty for violating court’s order, trial procedure in special magistrate’s court, power

of entry and search, procedure for investigation, procedure and power of environment court,

authority of environment court to inspect, appeal procedure and formation of environment

appeal court.

1.5.3 Compliance with DoE’s Guidelines

26. As mentioned above, the project activities fall under the ‘red’ category according to

the Environment Conservation Rules, 1997. For projects under this category, it is mandatory

to carry out IEE and subsequently EIA including Environmental Management Plan (EMP)

and where necessary develop a Resettlement Plan for getting environmental clearance from

the DoE. The DoE has issued EIA Guidelines for Industries and addresses the IEE and EIA

for several industrial sectors and activities. Each Project Proponent shall conduct an IEE or

EIA and is expected to consult and follow the DoE guidelines. The provisions of the

environment legislations and the EIA guidelines of the DoE have been reviewed under this

study. The DoE has issued application procedure for obtaining site/environmental clearance.

27. Environmental quality standards for air quality, noise, odor, sewage discharge,

industrial effluents, and industrial project emissions for Bangladesh

28. The Environment Conservation Act, 1995 and the Environment Conservation Rules,

1997 are the main legislative base in Bangladesh for protection and conservation of natural

environment. The Environment Conservation Rules (1997) place activities of power plant

into the Red category during the time of EIA study but the with the amendment held in 2018

made all substations project as orange B category. In this study, all compliance addressed

regarding the policy standard set during the EIA stage and monitoring of this project

completed following this way.

29. However, the Safeguard Policy Statement (SPS) of Asian Development Bank has

also been reviewed since ADB is financing the project in partnership with the GoB. As per

the ADB categorization, the sub-station construction activities are under the category B

considering the significance of the project’s potential environmental impacts. Therefore, the

EMP is prepared based on the combination of both the national and the ADB.

30. The environmental standards are determined in the Environmental Conservation

Rules. The standards for air, water, sound, odor and other components of the environment is

started to monitor in accordance with the standards specified in Schedules - 2, 3, 4, 5, 6, 7

and 8. The Bangladesh standards, in general, are less stringent compared to the developed

countries. This is in view to promote and encourage industrialization in the country. The

Bangladesh standards are not for any specific period of time. There is no provision for partial

Introduction

10

compliance too. For this reason, monitoring is based on the national standards unless there

is absence of clear standards; only then ADB’s standard is being considered.

31. Following IESCs and parameters are selected for monitoring in DESCO’s 24 sub-

station areas which have presented in Table 1.2.

Table 1.2: Selected IESCs and Parameters

IESCs Parameters

32. The results of the monitoring are needed to compare the established benchmarks/

baseline and compliance status and help to identify the areas where adverse environmental

and social adverse impacts are still occurring. It would be helpful to formulate the corrective

2.4 Methodology

2.4.1 Physical Environment

Ambient Air Quality

42. Air quality is an indicator of purity of air for respiration process of human being plants,

and animals. Poor air quality can affect human health and deteriorate surrounding

environment. Air quality was monitored through visual inspection as potential pollution

sources were from external air contamination. CEGIS engaged “Development Solutions

Consultant Limited “as 3rd party to conduct air quality test in the project sites.

43. To assess the baseline condition of the project areas, ambient air quality monitoring

was conducted for 8 hours at different project sites and then the average value of ambient

air quality has been used for the DESCO project area. The parameters were SPM, PM2.5,

PM10, Carbon Monoxide (CO), Oxides of Nitrogen (NOx), and SO2. LATA Envirotech APM

250 with Combined PM10 Sampler was used for the measurement of particulate matters and

for gaseous pollutants LATA Envirotech LES 411 was used. To monitor carbon monoxide

(CO) HTC CO-01 meter was used and value is expressed in ppm. The air quality monitoring

results provided by the Development Solutions Consultant Limited are not only been

presented but also have been compared with the national standards.

Noise level

44. Noise level is an important parameter as excessive noise may create disturbance to

local communities, ecosystem and workers at worksite due to project activities. Short-term

noise exposure can be overcome with rest, but if exposure is sustained, it may result in

irreversible long-term damage. Hearing loss in the workplace can lead to safety risks if

workers are unable to hear alarms or critical communications from other workers. Noise level

was perceived from individual acoustics of monitoring team. Noise monitoring is important

for any big construction activity as excessive noise may create disturbance to the wild life,

indigenous species, fragile ecosystems, communal stability in case of sudden intrusion and

workers due to construction activities and subsequent increased traffic movement.

45. Thus, ambient noise level has been monitored monthly at nearby sensitive receptors

around the construction site (including substation site) of this project. Each time, noise level

has been recorded using portable noise level meter for a two minutes time span at 5 minutes

interval depending on the site condition. Noise level has been recorded at day time only as

the construction works held only at day light hour. A probable increase in noise level in the

same area may provide the tools for assessment of impact on environment.

Waste Management

46. Infrastructure work for any development, usually generate variable quantities and

types of waste materials which have the potential to cause adverse environmental impacts

during generation, storage, transport and disposal. For this reason, the project aims to

implement waste management procedures immediately after the commencement of the civil

works in order to maintain minimal potential impacts to the environment. The project sites

were observed visually during sites visit to investigate concerns related to waste disposal.


14

Soil Quality

47. Sub-soil investigation is very important for proper planning and designing of the

structure which confirm the safety and stability of the structure. Thus, National Survey

Organization has been performed the sub –soil investigation for the construction of proposed

design, supply installation and commissioning of 24 nos 33/11kv Sub-stations. National

Survey Organization has executed Standard Penetration test (SPT), different field and

laboratory tests for investigation of sub-soil. They have evaluated bearing capacity of soils at

different layers. A number of bore holes have been drilled at a particular depth depending on

the project sites. We have been reviewed and incorporated the sub-soil investigation report’s

data for understanding the soil condition of the project sites which are provided by Siemens

Bangladesh Ltd.

2.4.2 Biological Environment

48. Proposed substation sites are situated in urban area, so urban ecosystem as well as

vegetation and wildlife are major components for this environmental monitoring.

Terrestrial Vegetation

49. Project site specific data (i.e. Cocos, Psidium, Cynodon, Scorpia, Croton, Leucas,

Cyperus, Chan grass) were collected through visual observation and use of GPS, noise

meter, iPAD etc. instrument for proper ecological monitoring. In addition, local people were

interviewed for getting data. Monitoring of intercultural operation was done quarterly through

consultation with stakeholders and local people.

Flora and Fauna

50. Flora and Fauna of all sites observed through regular field visit. The impact of project

implementation (i.e. land development; vegetation clearing, Labor and vehicle movement) on

small mammals, amphibians, reptiles and local urban birds have been identified through in

depth observation and consultation relevant stakeholders according to the prepared

checklist.

3. Monitoring Results

3.1 Introduction

51. For the commencement of the project implementation, Dhaka Electric Supply

Company Limited (DESCO) has made a Contract Agreement with Simens India in

consortium with the Siemens Bangladesh to Design, Supply, and Install & Commission 24

(twenty four) 33/11kV Substations in Turnkey Basis in DESCO area under the Dhaka and

Gazipur districts against Bid No. IFB 01/2016, Package-C1 of Lot-3 under ADB Loan No.:

3087- BAN: under “Power System Expansion and Efficiency Improvement Investment

Program” (Trench 2). After getting the Topographical Survey report they have started their

construction. Presently, there are twenty one (21) substations where the construction work is

ongoing. The environmental monitoring (3rd Phase) has been completed based on the

construction actitivites of these substations and impact due to the project implementation. All

activities3 related to the construction observed and findings of social safeguard monitoring

compiled following the ADB social safeguard policy and ADB –Bangladesh loan covenants.

3.2 Physical Environment

3.2.1 Ambient Air Quality

52. Ambient air quality data at the project site were measured to ascertain the current

quality of air. The aim was to develop the baseline air quality data and to compare the same

with the air quality data during project activities to check if there is any high air pollution

developed due to the construction activities and to design adequate mitigation measures, as

applicable.

53. The major air pollutants in Greater Dhaka City are nitrogen oxides (NOx), sulphur

dioxide (SO2), suspended particles matters (SPM), PM10 and PM2.5 (particulate matter with

diameter of 10 and 2.5 microns or smaller), carbon monoxide (CO), carbon dioxide (CO2)

etc. Motor vehicles, construction activities, uncontrolled emission from hundreds of brick

fields around the city, etc. are the major source of these pollutants particularly the PMs.

Dispersal of these pollutants greatly depends upon factors like prevailing wind direction and

other weather conditions, atmospheric stability, height of the source.

54. The air quality test for this project has been done during January, 2018 which is

winter season and in winter the pollutant level particularly PMs level increases to a great

extant where as in summer the heavy shower cleans the air to a great extant. CEGIS

engaged “Development Solutions Consultant Limited “as 3rd party to conduct air quality test

in the project sites the test was carried out for 24 hours except CO for 8hrs at and around

the project sites (Figure 3.1) from 15 January to 25 January 2018. The parameters were

SPM, PM2.5, PM10, Carbon Monoxide (CO), Oxides of Nitrogen (NOx), and SO2. The

weather was mostly sunny during the test period.. The average values of ambient air quality

result has been shown in Table 3.1. The air quality analysis of Tongi area is in progress and

will be presented in the next report.

It is evident from the test result that only PMs(SPM, PM10 & PM2.5) are above

the Bangladesh standard limit. The reason being as explained above. Other

pollutants are well below the standard

The concentration of PM10, PM2.5 and SPM of DESCO project area is higher

than the Bangladesh standard limit. From the above data, we have found that

the amount of PM10, PM2.5 and SPM are maximum which are 243 ,137 and 302

µg/m3 respectively . On the other hand, concentration of SO2, NOx and CO*

have found within the Bangladesh standard limit. The air pollution levels have

been compared with the Bangladesh Ambient Air Quality Standard as adopted in

2005.

During field visit, no significant internal and external sources of air pollution was

observed in the project sites that would deteriorate air quality. Due to vehicular

movements, digging of the earth and loose earth materials (e.g. soil, sand), some

dust particles were observed in the project area. Heavy construction machineries

were used to carry out pile work which caused scanty amount of SOx and NOx

which is negligible.

During field visit it was also found that the EPC contractor is spraying water once

in a day in the construction site to maintain the air quality within the standard.

However, the constructional activities do not cause air pollution of the project

sites. The overall air condition of Dhaka city is comparatively polluted for which

the air qualities of the adjacent project sites are deteriorated.

3.2.2 Noise Level

55. The noise produced during pilling, vehicular movement and other construction

activities made a considerable impact on the human settlement around the project area. The

disturbance hinders public concentration to continue their activities during construction. Due

to the construction of boundary walls, the noise wouldn’t be produced beyond the boundary;

therefore, a short term effect due to noise pollution is considered as the negligible impact for

the community people around the project area.

56. During this visit, it was noticed that most of the workers were not comfortable in using

earmuffs. The contractors were suggested to provide earmuffs to all workers. The labours

are exposed approximately eight hours per day to the loud noise which can cause acute

damage to their hearing system, leading to hearing loss.

57. Though the project sites are within developing residential area where no

considerable human settlement around the project site has yet been set up that could be

affected by noise pollution.

58. Vehicular movements around the project sites were relatively moderate. Hence,

noise generation from external sources was insignificant. The average noise level of the

project sites are shown in the table 3.2 below along with the standards of noise levels for

different zones of Bangladesh. According to the following table it is found that the noise

level of Uttra sector 14 is higher than the other project sites. The average noise level of all

sites is negligible regarding the noise pollution aspect and it is not creating severe problems

for the locality near to the project area.

3.2.3 Waste Management and Sanitation System

59. Waste management system at project sites was relatively good. Most of the sites

were good in terms of prevalent solid wastes. Dustbins were present at the project areas for

cooking and other organic disposals. Workers should be more encouraged and guided

properly to use dustbins as they show less interest to use them properly. It has been advised

accordingly to improve the waste management system.

60. There were separate arrangements of sanitation facilities for officials and daily

workers in the project sites. No form of water stagnation was observed during the monitoring

period within the project sides.

3.2.4 Soil Quality

61. Soil is an important component of environment management as well as proper

planning and designing of the structure. We have been reviewed and incorporated the sub-

soil investigation report’s data for understanding the soil condition of the project sites which

are provided by Siemens Bangladesh Ltd in the following table (3.4 to 3.20)

3.3 Ecosystem and Biodiversity Conservation

62. This report mainly deals with the ecological resources might have a chance of being

afflicted due to the construction activities of 21 substations. The construction activities were

found in various stages at different sites during the visits. There were no ecological

resources in the all the substations, except Uttara section-14 and Mirpur DOHS. Most of the

substations sites were developed and paved by infrastructures of DESCO already. At Uttara

14 section, the main floristic composition was found with some fruit trees. Therefore, these

trees were being used by avifauna for resting and roosting behaviors.

Figure 3.2: Project Area at Uttara, Section-14

63. Clearing those vegetables might have some impacts of the existing wildlife there. As

the area of substation is very small in size, the existing surrounding nature can support the

wildlife without applying any mitigation measures.

64. On the other hand, Mirpur DOHS, which was situated, near the ditch, the

construction materials and wastes were being drained into the ditch. This might have some

negative impacts on aquatic life forms and their ecosystems. For instance, increase of

turbidity can reduce the light penetration in the water body and ultimately low food

production for fishes. The draining of construction wastes are not a problem in all the sites

as some sites have good facilities to drain out in drainage system. Among the all sites, some

of them were covered by seasonally grown grasses (small and tall). Most importantly, there

were no threatening species in the substation sites at all.

65. In case of faunal species, except some avifauna, there were no potential wildlife

habitats, those needs to be taken care of. Therefore, very minimal changes of ecological

resources have been observed during visits of all the substations. In a nutshell, there wasn’t

any significant impacts been found on existing wildlife and vegetation during the construction

periods of 21 substations.

66. It is better to mention here that during the night, no construction activities were

performed. Therefore, noise and light was not hampering the wildlife during night anyway.

The monitoring indicators regarding ecological resources and their complaince status are

presented in Appendix B.

69. At this stage, There is no Grievence redress comitee to address the grivence redress

but the EA will assist the grivence redress mechanism through their institutional

arrangement. As there is no construction activities, no sign provided at the project office to

accept peoples complain as well as redress the grivences. The subdivisional engineer will

work as the field officer and would be responsible to arrange consultation for peoples

awareness at the respective project sites.

70. Presently, With the starting of construction activities, a sub assistant engineer is

playing key role to understand the people problems (if any related to the project activity) and

visited three sites. In addition, phone number attached in each station to get compliant and

emergency response during the construction activities.

5. Specific Environmental Management Plan

71. The site specific Environmental Management plan is suggested by the EPC

contractor (i.e. Simmens India). At this stage, it is found that they have that plan to guide

their works for these three substations locations. In their plan, Simmens have the plans to

manage environmental issues during the construction phase of the project. Based on the

following table 5.1, Simmens India started the construction work at the three locations

whereas the construction activities continued based on this specific environmental

management plan.

6. Conclusions and Recommendations

6.1 Conclusions

72. This monitoring was conducted twenty one (21) substations and explored the

compliance status based on ADB safeguard policy, EMP provided in the EIA, Bangladesh

Govt and ADB loan covenant. it ur proposed locations have been identified and existing

physical, biological and social conditions observed to get an insight about the base situation.

In this stage of environmental monitoring, the environmental management system and action

plan, occupational health and safety, workers’ wellbeing, biodiversity and sustainable

management of natural resources have been observed through monthly field visit for

particular project area following selected indicators mentioned in the checklist. Thus, a

comprehensive environmental monitoring result has been compiled and suggested the

corrective action plan for further improvement on non compliance status. Finally, an

implementation plan based on Corrective Action Plan (CAP) has been recommended in this

environmental report.

6.2 Recomendations

73. For the effective compliance staus, following recommendations are proposed by the

study team to be followed during the construction phase of these projects:

Though construction materials like sand and soil were not covered with polythene

at all project sites. This might cause dust pollution in dry condition. Thus, it is

required to cover the construction materials properly.

The noise level should be limited during the construction expecially the pilling

stage of the project implementation.

Earmuff should be available in adequate numbers for all labors working during

construction.

Separate Dustbins for both disposal and non disposal waste should be set within

the project during implementatiion.

The use of PPE should be ensured through regular monitoring by the monitoring

team of PMU to avoid the risks for further accidental case.

More awareness is to be created among the workers and community dwellers

regarding the health and safety risks associated with the construction phase of

the project.

One paramedic doctors, and an ambulance need to be made available for the

labors in case of any injury and accident.

Feedbacks from the labors taken to understand their problems during the weekly

toolbox meetings on health and safety, as well as the other governing

environmental and social issues should be initiated.
