Semi Annual Monitoring Report

For ASHUGANJ 450 MW (NORTH) COMBINED CYCLE POWER PLANT PROJECT (CCPP) (Ashuganj, Brahmanbaria)

Period : 11th Semi Annual (July– December, 2019) Monitoring : Ambient Air, Water & Noise Quality

EXECUTIVE SUMMARY

During the period from July to December 2019 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).

4.1 Major Environmental activities of the project

Major Environmental Activities of the project during operational period are given below:

Influx of workers Transportation of equipment, materials and personnel; storage of materials Power plant operational activities

4.2 Methodology

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 18th May 2019. 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.

4.2.2 Methodology for measuring Stack emission 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 02/10/2019)

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 18th May 2019 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 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 total CO2 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

25

blocking drainage lines and would be aesthetically displeasing. Proper disposal of these wastes are described in Section 4.3.

Solid waste of domestic nature that would be generated in the work stations at the plant 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.

Assessment of 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 plant activities include water, air quality and noise level. As discussed above, water quality could be affected mainly by plant activities such as mobilization of equipment, personnel (e.g., solid and liquid waste from work stations) and discharge of hot water. Effects of solid and liquid wastes generated during operational phase would not be very significant, because mitigation measures as outlined in Section 4.3 are adopted. The overall negative impact of such activities is likely to be “short-term (Sh)” and of “low” intensity.

Table 4.16: Effect of project activities on physico-chemical environmental parameters during operation phase Physico-chemical Environmental Examination parameters Positive Impact No Impact Negative Impact Low Moderate High Low Modera High te Air Quality X (Sh) Noise Level X (Sh) Drinking Water Quality X (Sh) River Water Quality X (Sh) Ground Water Quality X (Sh) 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 operational 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 in dust reduction. Bared areas at the site are properly covered, roads are properly cleaned and water sprayed in order to minimize concentration of dust in air when dust increases. Vehicle movement to and from 26 the site are properly managed to ensure that it 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 from the offices and work stations 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 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 plant site. 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 work stations and office areas are collected and stored separately (i.e., without mixing it with construction wastes/debris) in designated dustbins within the 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 CW 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 plant area, 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, 2019) during the o n g o i n g operational works. Ai r s a mp l es were 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, 2019 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,

2019 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, 2019 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 operational period, because use of heavy equipment a n d electricity generation activities. 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.

27

Waste anagement and process waste monitoring: Appropriate disposal of normal solid waste in sanitary landfilling site 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.

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. All slopes are protected and suitable erosion protection measures are implemented following ADB Environmental Safeguard Policy Guideline 2009 and IFC/World Bank Thermal Power Plant Guidelines 2008 & 2017 to reduce any impact from runoff during the monsoon rainy season and all the year round.

Health and Safety: The general health and safety of workers is safeguarded with the provision of medical and health facilities on-site, the provision of personal protective equipment (hard hats, safety belt, full body safety harness, ear plugs, ear muff, welding shield, grinding shield, safety shoe, safety goggle, welding apron, hand gloves, safety jacket, anti-dust masks, anti-gas masks etc. as required). There is an emergency response system and workers and supervisors are received training on any accident and immediate medical facility in its own round the clock medical center. There is two full time emergency ambulances to provide immediate service if required. Safe drinking water and sanitation facilities are established and provided to all plant related employees (officer, staff and workers), contractors and visitors at the site.

Corporate Social Responsibility: APSCL has engaged skilled, semi-skilled and unskilled local people in this power plant activities for socio-economic development and to upgrade the economic status of local people as much as possible from its scope to provide job facilities for them. APSCL provides irrigation water though an irrigation channel from its cooling water discharge channel to Bangladesh Agricultural Development Corporation’s (BADC) water channels at free of cost to foster irrigation works in about 36000 acres of agricultural lands of Ashuganj and to help local farmers where expense and scarcity of water are major problems during irrigation seasons. APSCL provides free treatment for emergency services to neighboring local peoples and any injured people from traffic accident. APSCL also provides education facilities to local peoples in its school.

6.0 Implementation of Grievance Redress Mechanism and Complaints Received from Stakeholders

There is a grievance redress mechanism developed in the plant 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 value 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.
