Executive Summary
This is the 4th phase of environmental monitoring commenced on July 2018 and continued
until December 2018 through monthly field visits by the consultant. In this stage, there are
twenty one (22) substations where the construction works are ongoing and this study
covered all these substations. The monitoring team visited and observed all construction
activates and consulted with relevant stakeholders according to the prepared checklist on
physical i.e. air quality, waste management, noise levels and soil quality, ecosystem and
biodiversity i.e. terrestrial 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. The recorded
noise levels showed that the minimum levels are at the entrance. The noise readings near
the construction zone were unsteady due to different construction activities. The impact of
this noise level is considered as insignificant as it is more temporary than permament. The
solid waste is maintained by the EPC contractor. The risks for solid waste disposal is very
low as the sites’ waste managements are found to be in satisfactory condition.
During the environmental monitoring, air quality was monitored by an air quality monitoring
machine at the project sites as well as through visual inspection. CEGIS used dust track
aerosol monitor model 8533EP which is an air quality monitoring machine. Based on the air
quality results, air quality were checked to be satisfactory at the project sites, whereas no
external source of air pollution was observed that can deteriorate air quality in the project
areas. During field visit, it was also found that water was sprayed every day to control
fugitive dusts and other particles when earth materials become suspended. The noise levels
were measured during day time at different project sites. Noise showed the minimum level at
and around the project sites. Waste management system, restoration of ecological resources
at different project sites were relatively good.
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 have been 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 Initial Environmental Examination (IEE) and
Environmental Clearance Certificate have been obtained from the DoE. As per the GoB
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 GoB (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, Environmental Management Plan (EMP) was prepared following the
national guidelines of Bangladesh and policies of the ADB. 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.
Introduction

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
Bangladesh Environmental Conservation Act (BECA) 1995 and Bangladesh
Environmental Conservation Rules (BECR) 1997.
National Environmental Laws Compliance Requirement Performance of DESCO
Bangladesh Environmental
Conservation Act (BECA) 1995
and Bangladesh Environmental
Conservation Rules (BECR)
1997
The Construction of Twenty
Four 33/11kv Substations in
DESCO Area requires
environmental clearance
certificate (EC)
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 (three) 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.
Introduction
9
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 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 according 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
Introduction
10
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 night-time is counted from 9pm to 6am.
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, odour, 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) places 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 the ADB has also been reviewed
since ADB is financing the project in partnership with the GoB. As per the ADB
categorization, the substation 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, odour 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 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 substation
areas which have presented in Table 1.2.

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 actions accordingly and in a timely manner.
1.5.4 ADB Loan Covenants with the DESCO
33. According to the Loan Covenant Article (II), section 2.01, DESCO should carry out the
project, with the due diligence and efficiency and in conformity with sound administrative,
financial, engineering, environmental and power sector practices. For the execution of
project following criteria should be followed.
Implementation arrangement
34. DESCO should ensure the project implementation in accordance with the detailed

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 by an air quality monitoring machine at the
project sites as well as through visual inspection as potential pollution sources were from
external air contamination. CEGIS used dust track aerosol monitor model 8533EP which
is an air quality monitoring machine. This is a desktop model with external pump. This
machine is used for outdoor monitoring applications and it can measures mass
concentration such as dust, smoke, fumes and mist. It was applied for fugitive emissions
monitoring. This Dust track monitor is continuous, real time, laser photometer that
measures mass fraction concentrations to PM1, PM2.5, PM10 and other particles that can
be respired. The value is expressed in µg/m3.
43. The machine was calibrated before starting sampling at each time. Clean brush and
isopropyl alcohol was used to clean out side, inside and imp actor plate. Then dry in air
thoroughly and applied 2 drops oil to the imp actor plate. Then pressed Run mode for
sampling mode options. Log mode starts and stops the instrument at specified time, run
for a specified test length, and performs multiple tests of the same length with a specified
time period between tests. The air quality monitoring results 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. Hence, 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 2 (two) minutes time span
at 5 (five) minutes interval depending on the site condition. Noise level has been
recorded at day time only as the construction works held only at daylight hours. 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
Approach and Methodology
16
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.
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 substations.
National Survey Organization (NSO) 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
particular depths 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. Different biological indicators have been monitored both through monthly physical
observations and public discussions at the under constructed substation sites. An
ecologist have visited the substation sites and collected the information on vegetation
clearance, plantations, wildlife disturbance, and bird habitat status using a formatted
checklist. Public discussions have been performed mainly through application of Key
Informant Interview (KII). The substation staff, labours and respective officers were
considered as the key informants.
Terrestrial Vegetation
49. Vegetation clearance has been ensured through visual observation of the green
coverage and denuded areas of the construction sites and thus compared in different
monitoring tiers. Status of plantations and the species composition of planted areas also
confirmed through physical observations.
Flora and Fauna
50. Information on wildlife disturbance due to excess lighting, movement path blocking has
been observed by direct observations and through KII with substations officials and
construction workers. Bird nesting and roosting habitat also sighted during field
inspection at the constructed sites and detect the changes by comparing the status in
different regular monitoring visits.

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 Siemens 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 two (22) substations where the
construction work is ongoing. The environmental monitoring (4th phase) has been
completed based on the construction activities of these substations and impact due to
the project implementation. All activities 2 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. In summer the heavy shower cleans the air to a great extant, but in winter
the pollutant level particularly PM levels increase to a great extant.
53. Dispersal of these pollutants greatly depends upon factors like prevailing wind direction
and other weather conditions, atmospheric stability, height of the source. CEGIS used dust
track aerosol monitor model 8533EP which is an air quality monitoring machine to conduct
air quality test in the project sites. The test was carried out for 1 hour at and around the
project sites (Figure 3.1) from 20 November to 10 December 2018.
54. This Dust track monitor is continuous, real time, laser photometer that measures mass
fraction concentrations to.The parameters were PM1, PM2.5, PM10 and other particles that
can be respired. The weather was mostly sunny during the test period. The average values
of ambient air quality result has been shown in Table 3.1 and Table 3.2. The air quality
analysis of Ahsania Mission Cancer Hospital and Mohakhali DOHS area are in progress
and will be presented in the next report.

55. From the monitoring Test Results (Table 3.1 and Figure 3.2) of Air Quality Monitoring at
DESCO project areas, we have found that the concentration of PM2.5 area is higher than
the Bangladesh standard limit. On the other hand, concentration of PM10 have found within
the Bangladesh standard limit except at Kazipara Switching Station which is 191 µg/m3.
56. 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. The
overall air condition of Dhaka city is comparatively polluted for which the air qualities of the
adjacent project sites are deteriorated.

On the other hand, inspection of the available data shows that concentration level of PM10
within the Bangladesh standard limit except Tilagati, Tongi Sataish, Kalshi, Merul Badda and
Uttar Khan and the concentrations of these sites are 208 µg/m3 , 222 µg/m3, 215 µg/m3 and
176 µg/m3 accordingly. Due to vehicular movements, heavy construction machineries, digging
of the earth and loose earth materials (e.g. soil, sand), some dust particles were observed in
the project area which is negligible.
58. During field visit it was also found that the EPC contractor is regularly spraying water in
the construction site to maintain the air quality within the standard and no significant internal
and external sources of air pollution was observed in the project sites that would deteriorate air
quality. 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. The air quality data of Ahsania Mission Cancer
Hospital and Mohakhali DOHS will be included in the next report as the sites works are in
progress in the project sites.

3.2.2 Noise Level
59. 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. Most of these
activities are limited to day time only. The impact of this noise level is considered as
insignificant as it is temporary.
60. 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.
61. 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.
62. 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 3.3 below and Table 3.4 along with the standards of noise levels for
different zones of Bangladesh.

3.2.3 Waste Management and Sanitation System
Existing Substation
63. 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. There were separate arrangements of sanitation
facilities for officials and daily workers in the project sites.
64. There overall scenario of the Civil Aviation (CAAB), DOHS Mirpur, Mirpur-6, Agargaon-2,
Baunia, Tongi (BSCIC), ADA, Tongi-2, and Kazipara Switching Station were same. No
form of water stagnation was observed during the monitoring period within the project
side.

good in terms of prevalent solid wastes dustbins were presented at the project areas for
cooking and other organic disposals. But at Satarkul area, the dustbins were present but
it is not use properly. Otherwise, the overall scenario where same. The 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.
66. 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 sites.

3.3 Biological Environment
68. The existing 9 (nine) substations have some distinct features and almost same
ecological scenario. Each of the sites has tiny scope of growing vegetation as most of
the lands are paved by civil structures. Hence the sites contain mere vegetation with
seasonally grown herbs and shrubs. Depending on the vegetation, the wildlife
occurrences is limited and mainly observe some local birds and rodents like mouse and
mongoose. Considering the above overall situation, the compliance of ecosystem and
biodiversity conservation status is followed through last monitoring visit.
69. Out of 9 (nine) sites, 7 (seven) sites limiting the vegetation clearance within the
development footprint and no additional clearing for construction have took place for
avoiding the ancillary facilities expansion outside the footprint area. Uttara section-14
and Tongi-2 area have been subjected to cut down of 3 (three) mango trees.
70. Any of the sites followed/ informed disturbances to wildlife movement and the entire sites
construction footprint have clearly demarked by boundary fences for limiting construction
activities within the site. All the sites have limited the use of night lights which have
minimized the disturbance to nocturnal wildlife. No one site observed any bird nest or
core habitat of any rodents. None of the sites have started plantation activities in them
yet and Mirpur-6 and Agargaon-2 sites have no available space for plantation.
71. The proposed new substation sites featured with bushy vegetation with low densities of
herbs and shrubs. Only the Barura site developed within the agricultural land most of the
sites have already been developed for the construction of civil structures and then after
assembling the mechanical equipment. The observations on ecosystem and biodiversity
conservations are satisfactory most of the sites which revealed from last monitoring tier.
No one sites violate the vegetation conservation protocol outside the development
footprint area or eventually done the additional vegetation clearance outside the footprint
area for ancillary facilities.
72. Only the Lake City Concord site had no clear demarcation of footprint area and some
sites like Basundhara I Block, Sholhati and Barura sites observed no fence surround the
footprint boundaries. Therefore additional vegetation clearance had occurred due to
placing of construction materials dumping outside of the area. Some tall trees will be cut
in Lake City Concord area due to space limitation. However, none of these above four
sites, no threatened species was recorded. Except the above, occurrence of Bengal fox
have been informed in Satarkul and Barua sites and may be interrupted their movement
due to construction works. Local birds are rarely roamed among most of the proposed
substation sites and some small mammals like mouse and shrew have been relocated at
the nearer places. All the sites properly compiled to limiting night light using. Native
plantation yet not been started in the area
73. Considering the overall situation, there were no significant negative impacts on the
existing vegetation and wildlife. The monitoring indicators regarding ecological resources
and their complaince status are presented in Appendix B.

6. Conclusions and Recommendations
6.1 Conclusions
79. This monitoring is conducted on twenty four (24) substations and analysed the
compliance status based on ADB safeguard policy, EMP provided in the EIA, the GoB
and ADB loan covenant. The compliance status on Environmental and Biological
compoents addressed based on the prepared checklist. Therefore, the findings of
environmental monitoring 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 Recommendations
80. For the effective compliance status, 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 especially the pilling
stage of the project implementation.
Earmuffs 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 implementation.
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
