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.

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.
Approach and Methodology
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.

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.

Monitoring Component: Biological Environment
Ecosystem and Biodiversity Conservation
Bird’s habitat loss, damages of herbs, shrubs and degradation of ecosystem and biodiversities due to construction works.
No disturbance on wildlife movement ✓
Limiting the use of night light ✓
No plantation of non-native species ✓
The removal of vegetation shall be restricted to the development
footprint, which should encompass areas that are already relatively disturbed in preference to clearing vegetation
✓
Any additional clearing for construction will compound the impacts,
so ancillary facilities outside the footprint shall be avoided ✓
The construction footprint shall be clearly demarcated. The clearing boundaries are to be shown to machinery operators with the instruction that machinery is not allowed to operate outside the boundaries. The area is then cleared to minimize disturbance to adjacent areas
✓
The boundary will be fenced and the area cleared in such a way that
the footprint shall not be extended during clearing works. ✓
If the area is to be revegetated, preference should be given to
naturally occurring species that are recognized as non-invasive species.
