ABSTRACT:-

It has been realized that thermal power plant has several primary as well as secondary environmental impacts on Singrauli for which assessment studies are necessary for mitigating the possible future impacts that a project might have on the environment. These studies enable the decision maker from the organization or government agencies to consider environmental impact due existing & upcoming project to take necessary steps to prevent adverse environmental impacts of existing and upcoming project.

INTRODUCTION: Singrauli area consists of north east part of Singrauli district of Madhya Pradesh & southern part of Sonebhadra district of Uttar Pradesh. It is the 50th district of Madhya Pradesh which is disintegrated from Sidhi district on 24th May 2008. It is an emerging power hub of India due to availability of coal & water. N.C.L has ten working open cast coal mines which produced 70.021 million tonnes of coal during 2012-2013. N.C.L. has planned to reach 80 million tonnes by the year 2016-2017. Water Rihand dam has reservoir capacity of 129 million cubic meter & catchment are 5148km2.Dam & spill way. Dam height is 91meter & length 934meter. Because of these two factor that is availability of coal and water. Electricity is generated in the minimum cost.

Power Generating capacity of India is 211766.22 MW that is 100%, out of which 141713.6 MW that is 66.91% from thermal, 121610.88MW that 57.42% from coal based thermal power plant, 13732 MW from singrauli approximately 12 % of coal based thermal power plant. Near about 10000 MW under construction. Due to this much of power Generation in singrauli Lot of Air pollution occurs in the singrauli the main pollution content are SO2, NOx, PM10(RPM) & PM2.5 which are in very high Quantity and their chances to exceed beyond allowable limit .

1. PROPOSED MONITORING METHOD

   The focus in this study is to find out the ambient air quality in singrauli district at different location so we are able to

   identify actual pollution content in the Singrauli Region due to thermal power plant. The study mainly focus on content SO2, NOx, PM10(RPM) & PM2.5 while studying air pollution two more things mainly come into the picture that is mercury and ozone but we have not considered this in our study scope, environmental impact assessment due to thermal power plant in singrauli at 6 different location in Singrauli. The data presented in this paper were compiled as a part of a research project. Pollution that occurred at different stages in thermal power plant in the power generating industry at the industrial site. This statistics may serve as an important feedback instrument to monitor pollution extent in singrauli. Following are the method adopted to find out content of this four air pollution content and instrument used to find out the same also mention in the table given below.

3. CONCLUSION

This are the parameter which are fluctuating as the reading are taken when pollution control measures has been taken max so2 is 16 (µg/m3 ) While max allowable is 80 (µg/m3 ) . so2 is very less than

allowable limit. Max NOx is 31(µg/m3) while max

allowable is 80(µg/m3 ) . Particulate Matter Max (PM2.5) is 65(µg/m3 ) which is more than max allowable limit that is 60(µg/m3 ).Particulate Matter (PM10) Max RPM 103 (µg/m3) which is also more than maximum allowable limit that is 100(µg/m3).

As all the reading are taken away from the emission point of power plant .this show that emission is somehow more than allowable limit . when all the power plant which are in construction phase when they start their operation then this limit is easily exceeded. So we should take care of all such factors as well as take necessary preventive action to control this emission level .so as to minimize health problem due to this particles to human being nearby Singrauli.
