1.0 INTRODUCTION 1.1 Background

NUPPL proposed to setup 3x660 MW Super-Critical Thermal Power Plant at at Villages Rampur, Bandh, Bagariya, Sidhaul, Lahuri-mau, Aswar-mau, Dharchhua & Sirsa villages (All, part villages) in Ghatampur tehsil, Kanpur Nagar district, Uttar Pradesh.

1.2 Purpose of the Report The preliminary objective of the report is: Change of fuel source from 100% domestic coal/ Blended Coal to 100% imported coal (which will be supplied by MSTC). Hence, NUPPL is submitting this addendum report detailing the justification and the impacts due to the proposed change of fuel source from 100% domestic coal/ Blended coal to 100% imported coal (which will be supplied by MSTC).

1.3 Justification for the Proposed Changes

Initially, Environmental Impact Assessment study for the said project was executed based on 100% domestic coal and blended coal. The domestic coal requirement is proposed to source from the allotted South Pachwara Coal Block, however the Environmental Clearance & stage I Forest Clearance for the linked coal block is not obtained and is in process.

Although the EC and stage I FC for the Pachwara South coal block allotted for the project are under process, it may take substantial time, therefore the proposal needs to be referred to the committee once again when the EC and stage – I FC for the linked coal block has been obtained.

In this regards it is proposed to use 100% blended imported coal for an interim period until the production from the South Pachwara coal block is initiated to meet the requirement of GTPS.

Coal Linkage Status Further, the company now intends to source Indonesian coal through MSTC. The Fuel Supply Agreement has been entered by NUPPL and MSTC (Annexure-I).



2.0 PROJECT DETAILS FOR 3X660 MW POWER PLANT 2.1 Fuel Requirement

The total imported coal requirement would be about 7.65 MTPA. The imported blended coal requirement for the proposed 3 x 660 MW thermal power plant with super critical technology is estimated as 7.65 MTPA. The detailed calculations for imported, domestic and blended coal is given in Table-1.

3.0 IMPACT ASSESSMENT For assessment of impact prediction, maximum power generation of 1980 MW (3 x 660 MW) is considered. Also solid waste and gaseous emissions are calculated based on worst coal quality.

3.1 Impact on Air Quality

The major source of emission from the proposed power plant is stack attached to boilers. Particulate Matter (PM), Sulphur dioxide (SO2) and Oxides of Nitrogen (NOx) are the major pollutants from the proposed power plant. The expected stack emission details are worked out for blended imported coal options. For blended coal, imported coal ICI3 and IC14 has been considered to assess the impact on air quality. The details are given in Table-4.

Prediction of impacts on air environment has been carried out by employing Industrial

Source Complex [ISC3] mathematical model based on a steady state Gaussian plume dispersion model designed for multiple point sources for short term. Air pollution modeling has been carried out by estimating GLCs at about 1200 receptors to obtain an optimum description of variations in concentrations over the site in 10 km radius covering 16 directions. The incremental ground level concentrations and resultant GLCs for PM10, SO2 and NOx are given in Table-5. Isopleths showing the incremental concentrations are given in Annexure-II.

SO2 36.56 36.86 30.24

NOx 16.02 16.02 16.02

From the above table, it can be observed that the incremental concentrations of sulphur dioxide for domestic coal option are much less when compared to the 100% usage of imported (Indonesia) coal. Also, it can be observed that even with the usage of imported blended coal, the incremental concentrations are below the emissions (due to usage: Blended coal of 70 Indigenous: 30 Imported Coal -5.36 MTPA). Hence, no significant additional air impacts are envisaged with the use of 100% imported coal in place of blended and domestic coal.

3.4 Impact of Solid Waste

The total coal consumption will be increased with the use of domestic coal and so the total ash owing to the high ash content. However, there will be no change in the other solid waste generation. The details of ash generation are given in Table-6.

The above table depicts that there is no significant impact on the environment due to change in coal from imported coal to domestic coal/blended coal.



Hence, NUPPL is requesting for the Usage of 100% imported coal in place of domestic coal/blended coal (Indonesia will be supplied by MSTC) as there is no significant additional impact on the environment.

5.0 CONCLUSION

As per the advice of Expert Appraisal Committee, MoEF, super critical technology is envisaged for the project. NUPPL has already obtained FSA with MSTC for Indonesian Coal Mines for supply of Imported Coal to the project. No significant additional impact is envisaged in air environment due to use of domestic coal/ blended coal in place of 100% imported coal. Hence, NUPPL requests to grant Environmental Clearance for the proposed change in coal from 100% Imported Coal to 100% Domestic coal/blended coal, as there is no additional consumption of resources such as land, water and coal and no significant additional increase in pollution load.
