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. Introduction

1.1 Background

1. The Government of Bangladesh (GoB) has set their goal in providing access to

affordable and reliable electricity for all by 2021. In this respect, Bangladesh has scaled

up its priority to strengthen the electricity production, transmission, and distribution for

overall growth and development of the country.

2. Dhaka Electric Supply Company Limited (DESCO) has taken several initiatives to

expand its infrastructure in the distribution system with the construction of the new line,

substations, and renovation of existing substations in order to enhance the electricity

distribution and meeting the increasing demand of Dhaka City North. This project titled:

Augmentation and Rehabilitation of Distribution System in DESCO Area has already

obtained the site clearance certificate (SSC) and environmental clearance certificate

(ECC) from the Department of Environment (DoE) of the GoB. The Siemens India

entrusted as the Engineering, Procurement and Construction (EPC) contractor to

implement this project. In this project, CEGIS is working as environmental consultant to

monitor the compliance status based on Bangladesh National Environmental Policy

Standards, Environmental conservation rules of the Asian Development Bank (ADB) and

loan covenant between the ADB and GoB.

3. In relation to the previous environmental monitorings, this 4th monitoring has been held

(from July 2018 to December 2018) and the compliance status has been checked based

the prepared checklist on physical and biological environment.

4. With the monthly field visit and following the mixed approach this environmental

monitoring has been completed (up to December 2018). The status of non-compliance

issues addressed in this Environmental Monitoring Report (EMR) and provide to upgrade

the status by expert judgement mentioning the Corrective Action Plan (CAP).

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.

Introduction

11

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.

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 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

arrangements set forth in the PAM. Besides, it is the responsibility of DESCO to ensure

their project management staff who have the qualification to undertake necessary tasks

of procurement, construction, supervision, inspection, and testing of equipment,

payments to contractors, monitoring, environmental and social safeguards due diligence

and reporting of progress relevant to the components under their responsibility.

Introduction

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


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.

During the field visit, the measured average noise level of the project sites (Table 3.3) shows that the average

noise level are within 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.

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

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.

3.2.4 Soil Quality

67. 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 section.

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

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

environmental and social issues should be initiated.

All addressed Non-Complaince Issues mentioned during the field visit should be

addressed

All newly built substation areas should fenced with high boundary wall during the

construction
