Semi Annual Monitoring Report

For ASHUGANJ 450 MW (NORTH) COMBINED CYCLE POWER

PLANT PROJECT (CCPP)

(Ashuganj, Brahmanbaria)

Period : 9th Semi Annual (July– December, 2018) Monitoring : Ambient Air, Water & Noise Quality

EXECUTIVE SUMMARY

During the period from July to December 2018 there is a discharge in control manner and for this,

there is no impact on the living things in the water body. Air Pollution caused by dust emission from

activities is controlled by good management practices like continuous water spray over the unpaved

or bare surfaces, covering soil materials pile and by completing of the pavement of bare surfaces.

Soil and water pollutions are also prevented by proper management like spill prevention and well

drainage system. Solid waste is managed by the waste management plan. Noise pollution is also a

regarding issue during generation of electricity. Noise level is reduced by proper traffic management

system and using of environmental friendly high technology electricity generating units and auxiliaries where main generator and turbine is under canopy system with sound attenuation

technique. Every personnel uses personal protective equipment to ensure own safety. The

remarkable achievement in this period is that till now there is no record of accident or injury. APSCL is committed to keeping the accident level at Zero by implementing its proper occupational

health and safety management system. This project also has a positive effect on the socio-economic

condition. Local skilled and semi-skilled peoples are engaged in different levels of construction and

operational activities and they are very happy for getting employment opportunities.

1.0 INTRODUCTION

The objective of the environmental s a f e g u a r d management and monitoring is to record

environmental impacts resulting from the project activities and to ensure implementation of the

“mitigation measures” identified earlier in order to reduce adverse impacts and enhance positive

impacts from specific project activities. Besides, it would also address any unexpected or

unforeseen environmental impacts that operation phases of the project.

The EMP clearly lay out: (a) the measures to be taken during both construction and operation

phases of the project to eliminate or offset adverse environmental impacts, or reduce them to

acceptable levels; (b) the actions needed to implement these measures; and (c) a monitoring plan to

assess the effectiveness of the mitigation measures employed. Environmental management and

monitoring activities for the under construction power plant project could be divided into

management and monitoring: (a) during construction phase, and (b) during operation phase.

The application of this plan involved an environmental control and monitoring of the work by a

technical team to verify compliance with all the indications, limitations or environmental restrictions

set forth in the Environmental Management Plan (EMP), EIA and the Project, with the minimize

damage caused by work on the environment.

The information obtained by the implementation of the Environmental Action Plan is required to

define preventive measures or define corrective actions.

The information generated as a result of implementing the Environmental Action Plan must be duly

forwarded to the Department of Environment (DoE).

4.2.1 Methodology for Air Quality Assessment

During the o p e r a t i o n phase of this power plant project, the important sources of emissions would

include those from the operations of equipment and machineries, vehicles carrying materials to

the site and taking debris out of the site and stack emission for electricity generation.

Monitoring and measurement of Suspended Particulate Matter (SPM), Fine Particulate Matter (PM2.5) &

Repairable Particulate Matter (PM10) was accomplished by Handheld Laser Particle Counter (Model

No: P611, AIRY Technology, Inc, USA) which was calibrated on 21st OCTOBER 2018. Ambient Air

Quality monitoring was done from four different places at Ashuganj 450 MW North Combined Cycle

power plant project described in Table 4.1 and illustrated in Figure 4.1 . Test Results of Ambient Air

Quality from these different places are presented in Table 4.8.

Stack emission is measured daily using Continuous Emission Monitoring System and the obtained data

is sometimes crossed checked by Testo 350 Flue Gas analyzer (Calibrated on 02/10/2017)

4.2.3 Methodology for Ambient Noise Measurement

To assess the noise generated by different activities it is essential to identify the equipment to be

used at various stages of the operation work. Therefore, an inventory of the probable equipment to

be used and their reference noise generation data are of utmost importance. The noise level in

control room was tried to measure in the maximum silent condition. Noise was measured at different

points of the project area at receptor levels ; Table 4.2 and described in Figure 4.2; like control room,

turbine building, Water Treatment Area, Transformer area, GIS area and other outdoor places to

determine the impact of noise generated from plant operational activities. The noise measurement was

carried out with Lutron Digital Sound Meter (Model No: SL-4012) which was calibrated on 08th

November 2018 and real time data was taken instantaneously. Four noise reading was taken for each

point placing the noise meter 1 meter above from the ground and 1 meter away from the source.

Measured noise level in the operational sites is summarized in table 4.8.

The Meghna River passes through from East to West direction near the project area and there are few

industries at the right bank of this river. So the water of this river is less polluted that was also found

from environmental monitoring. The DO level of this water is more than 6.5 mg/L which is within

DoE standard level. The BOD5 is also in lower level than DoE standards.

4.3 Semiannually assessment of operation impact on air, water, noise, operation waste

and labor camp management

4.3.1 Impact on Air Quality

The result for ambient air quality monitoring shows the SPM, PM10, PM2.5, concentrations of the

ambient air. From the analysis it is observed that the concentration of SPM, PM10, and PM2.5 is

within the allowable limit, as in the project area the different small constructions activities, highway

traffic movements were being done. So, the SPM and PM10 are found higher level during movement

of vehicle but after spraying of water and pavement of bare surfaces the dust level is reduced

remarkably low. Having construction activities many diesel vehicles were moving around and three

to four cranes were also under operation, so it can be thought that the NOx level would be higher

level. PM2.5 is composed of a mixture of primary and secondary particles, Primary particles are

emitted directly into the atmosphere and include soil-related particles and carbon particles from

fossil fuel combustion, and secondary particles are sulphate, nitrate, organic and elemental carbon,

trace elements and ammonium. The under constructed project is at Ashuganj in Brahmanbaria

district which is unplanned urban and planned industrial area, so the cumulative air pollution is high

in this area during the construction period which is now found low pollution level after implementing

mitigation measures during its operation period. Stack emission measurement during present

operational phase is summarized in Table 4.13 and the gaseous emission during the reporting period

is showed in Table 4.14.

Mitigation measures as outlined in Section 4.4 adopted to minimize the possible adverse impacts

of project activities on air quality.

4.3.2 Impact on Noise

During operational stage, major source of noise is expected to stem from electricity generation

points like turbine, generator and Boiler-HRSG and also to some extent from transport

vehicles. The operational phase can be broadly classified into two different groups:

• Machine operation, and

• Breakdown or Schedule Maintenance.

Results shows that, the noise produced from each of the location stay below the acceptable limit and this will not produce any significant health and environmental impact. However, in turbine building, noise is comparatively high. That’s why some mitigation measures are needed to be taken which is summarized in section 4.4.

4.3.3 Impact on Water Quality

Drinking, Surface water and ground water sample was collected and assessed in laboratory to determine any decoration of those water resources. The entire water sample is examined in good laboratory practice and results (Table4.9-4.11) shows that the water is not affected by power generation activities. The results from waste water samples were also declared that the water is discharge (Table 4.12) to the nearby Meghna river in a controlled manner.

4.3.3 Impact on Soil Quality

Four Soil samples were collected and assessed in analytical laboratoty to determine the concentration of several heavy metal concentrations. Result (Table 4.15) represent that the concentration of three heavy metals were remain below standard.

4.3.5 Impact on waste and labor camp

Construction debris and wastes to be generated during present small scale construction a n d o p e

r a t i o n a l phases are scrap iron, steel, wooden frames, piping, and other solid wastes. Most of t h e m a r

e generated toward the end of the construction phase during carrying out of the finishing works, while

the site will be cleared of waste materials. The volume of such wastes is likely to be significant.

Indiscriminate storage and disposal of these wastes could create local water logging and ponding by

blocking drainage lines and would be aesthetically displeasing. Proper disposal of these wastes a r e

described in Section 4.3.

Solid waste of domestic nature that would be generated in the labor sheds at the project site is not likely

to be significant in volume. But indiscriminate disposal of such solid waste would create environmental

pollution and unhealthy situation at the project site. These solid wastes are disposed of properly as

outlined in Section 4.3.

26

Assessment operational impact on air, water, noise, construction waste and labor camp

management

Table 4.16 summarizes the effect of project activities on physico-chemical environmental parameters

during construction and operational phase of the project. The physico-chemical environmental

parameters that could be affected by the project activities include water, air quality and noise level. As

discussed above, water quality could be affected mainly by project activities such as mobilization of

equipment, personnel (e.g., solid and liquid waste from labor sheds) and discharge of thermal water.

Effects of solid and liquid wastes generated during construction and operational phase would not be very

significant, especially if mitigation measures as outlined in Section 4.3 are adopted. The overall negative

impact of s u c h activities is likely to be “short-term (Sh)” and of “low” intensity.

Note: Sh=Short-term; Lo=Long-term

Deterioration of air quality during operational phase result from increased concentration of particulate

matter in the air from operational activities such as vehicular movement, wind-blown dust and poor

combustion of fossil fuel etc. However, these adverse impacts are greatly minimized by adopting

mitigation measures as outlined in Section 4.3.

The likely noise level to be generated for different o p e r a t i o n a l activities and its impact on the

surrounding environment were assessed using a noise meter. Results of the assessment are presented in

table 4. 8; shows that different operational activities would generate noise which is insignificant to create

adverse impacts.

4.4 Mitigation Measure

4.4.1 Air Quality

Pavement works of bare surf ace are fully complete t ha t h as significant contribution i n dust

reduction . Bared a r e a s at the site a r e properly covered, roads p r o p e r l y cleaned and water

sprayed in order to minimize concentration of dust in air when dust increases. Vehicle movement to

and from the site are properly managed to ensure that is does not significantly aggravate the traffic

problem and air pollution. Health status of a l l workers i s monitored regularly at power plant

medical center.

4.4.2 Water Quality

The human wastes f r o m t h e offices a n d labour c a m p are appropriately disposed of through

construction of sanitary latrines connected to appropriately designed septic tank system (consisting of

septic tank and soakage pit). Wastewater generated from different activities is not likely to be

significant in volume. Disposal of such wastewater are carried out by draining them in shallow pits (1

27

to 1.5 m deep) dug in the ground at appropriate locations. In all cases, the wastewater streams are

separated from the storm water stream, which is disposed of separately utilizing the existing storm

water disposal system at the Ashuganj complex. All sanitary latrines in office buildings and working

facilities of this plant are well designed and properly managed to prevent any kind of pollution.

4.4.3 Noise Level

Use “quiet” equipment (i.e., turbine, generator, auxiliaries and other equipments are designed with noise-

control elements);

Route truck traffic away from noise-sensitive areas, where feasible;

Installed sound barriers for pile driving activity, where practicable (e.g., use an acoustic curtain or

blanket around the point of impact);

Unnecessary vehicle movement are avoided 4.4.4 Solid Waste

The solid wastes of domestic nature generated mainly in the labor sheds and office areas a r e

collected and stored separately (i.e., without mixing it with construction wastes/debris) in

appropriate containers within the construction and operational sites. Aq u a t i c ma c r o p h yt e s a n d wa t

e r h ya c i n t h s a r e r a pi d l y c o l l e c t e d f r o m c w p u mp s t a t i o n a r e a t o p re ve n t b a d o d o r . The

solid wastes are disposed of away from the site (e.g., in a municipal landfill/waste dumping ground)

outside the complex, at the responsibility of the Contractor & monitored by APSCL. APSCL will also

install an Incinerator for hazardous and solid waste management.

4.5 Progress of Work Ambient air quality monitoring: Measurements of selected air quality parameters for PM2.5, PM10

and SPM has been carried out (July–December, 2018) during the o n g o i n g operational works . Ai

r s a mp l es we re c oll ec ted f or measurements of selected air quality parameters for PM2.5,

PM10 and SPM and analyzed data are summarized in Table 4.8

Drinking water monitoring: Drinking water sample was collected from supplied drinking water in

July–December, 2018 for analyzing pH, ammonia, nitrate, phosphate, As, Fe, Mn, Fecal and total

coliform. Test report also shown in Table 4.9.

River water monitoring: River water sample was collected from Meghna River in July–December,

2018 for analyzing temperature, dissolved oxygen (DO) along with BOD5, COD, Oil and Grease, and

selected heavy metals (Cr, Cd, Pb). Test report also shown in Table 4.10. Ground water monitoring: Ground water sample was collected from supply water in July–

December, 2018 for analyzing pH, TDS, ammonia, nitrate, phosphate, As, Fe, Mn, Fecal and Total

coliform. Test report also shown in Table 4.11.

Noise level monitoring: Noise level monitoring is also necessary during construction and operational

period, because use of heavy construction equipment a n d e l e c t r i c i t y g e n e r a t i o n a c t i v i t i e s . So,

Noise level data were collected from selected 4 points of every location and summarized in Table 4.8.

Storage of Hazardous Material: Storage of hazardous material like lubricating oil, transformer oil, SF6 gas cylinder, H2 gas cylinder, chemicals, Air filter and insulation materials are properly done in central store and chemical store with proper demarcation, secondary containment, safety warning signage and MSDS. Waste management and process waste monitoring: Disposal of construction debris away the site

and their appropriate disposal sanitary landfill are ongoing. Hazardous waste and non-hazardous waste

are also disposing by proper way. In fact till now no hazardous materials were generated from plant

operational activities.

28

Trees cutting: The project site has been established in bare field. So, there was no scope of tree cutting.

But tree plantation program and landscaping is going on for providing the better environment at the

project site and APSCL area that will also act as carbon sink. Others: There is no significant impact from this power plant activities on the existing road network in the project area.

So, very well balanced vibration preventing structure is constructed for turbine

to be operated at high rotational speed.

• Use of all kinds of respective personal protective equipment (ear muff and ear

plug for noise) are mandatory for all in the plant site.

• Noise levels are monitored regularly within the communities where nearest

potentially affected noise sensitive receptors are identified in order to take

timely corrective measures, if needed.

• Traffic noise is controlled by proper traffic management. Speed limit is

restricted as 10 Km/Hr in plant site.

32

Plant Effluents The power plant is expected to generate liquid effluents in

the form of oily water, plant cooling water, washing water,

blow down water, treatment system effluent and sanitary

wastewater

• The power plant water treatment system is designed to ensure that the wastewater

meets Bangladesh National Environment Quality Standards (BNEQS) before it is

drained into the drainage channels or used for arboriculture.

• The design of intake and cooling water structures are incorporated with measuring

to reduce impacts. In addition, good site management practices includes the

following are implemented and monitored:

1) This plant is designed considering as zero HRSG blow down and make-up

water. Proper treatment of contaminated water or cooling water before

discharge through discharge channel to natural water body.

2) Oil water separator is used for segregation and pretreatment of oil and grease

containing effluents prior to discharge to prevent water pollution.

3) No disposal of solid wastes into discharge structure.

4) Regular maintenance of site drainage system to ensure efficient operation and

to prevent siltation.

5) Sanitary and domestic wastewater are disposed to septic tank. No sanitary

wastewater are discharged to discharge channel or drainage system.

6) All discharge are complied with the local and World Bank guidelines.

and bypass stack).

• Continuous emission monitoring station (CEMS) are installed to monitor NOx,

CO2, CO, O2 in stack emission continuously.

• Sufficient plantation and gardening is done for carbon sink, temperature reduction

and for beautification.

Water Resources An adverse impact on the water resources will be

interpreted if it is established that the water consumed by

the Project has directly affected the ability of the

community to meet their water needs.

• Surface water (river water) is used for both drinking purpose and external use after

proper treatment.

• Water quality is regularly tested and monitored to ensure performance of water

treatment plant and for the safety of human.

• Employees, visitors, contractors, vendors and other peoples who come in this plant

are aware of least water consumption and water conservation. Awareness program

is an ongoing process for this issue.

6.0 Implementation Of Grievance Redress Mechanism And Complaints Received From Stakeholders

There is a grievance redress mechanism developed in the project site. But till now there is not

received any grievance to address.

7.0 Conclusion and Recommendation

The environmental monitoring report is consist of 8th Semiannually environmental monitoring reporting

based on monthly measured ambient air, noise, drinking water, ground and river water quality

parameters. Ambient air quality parameters were determined in the site with the help of high volume

sampler and noise quality was done by noise level meter. Drinking water, ground and surface water

quality parameters were analyzed in the laboratory. All of the mitigation measures are taken

following ADB Environmental Safeguard Policy Guideline 2009, IFC/World Bank Thermal Power

plant guideline 2008 and DoE, Bangladesh guideline.

From the analysis it is found that the ambient air quality results found within DoE standards. This values

is cumulative with surrounding ambient air and noise level. SOx and CO are not a problem of the

construction period of the power plant. But SPM, PM2.5, PM10 level during construction period of power

plant are controlled by taking proper mitigation measures and spraying of water.

Noise level quality of this plant has also been measured by both APSCl. According to the measurement,

the noise level around the plant area found within the allowable limit of Industrial zone both the day

and also at night time. The noise level are controlled by using modern, environment friendly, new and

fine-tuned equipment and plant machineries.

Surface water quality parameter at Meghna River was performed to evaluate whether this plant poses

any detrimental effect on the water environment. From the analysis it has been found that the project

does not cause water pollution to the natural environment. Otherwise, any spill is not detected next to

riverbeds around the worksite (oils, concrete waste or conglomerate asphalt, any color changes of the

water, etc.). Drinking and ground water quality is also found good.

House-keeping is also in good condition at the plant site. All solid, liquid and hazardous waste are

disposed to the designated container at the plant site. Most of the solid wastes are disposed by landfill.

The usable solid wastes are handed over to proper party for recycling. Liquid hazardous waste is

conserved and properly clean of the storage area. Hazardous waste is kept at designated places by

labeling.

Finally it can be concluded that the plant has minor detrimental impact for short period on the

environment in terms of ambient air and ambient noise during the operational period. The plant

provides a good working environment for the workers.
