| Emission Parameter        | TPPs (Units) installed before 31st December, 2003                                                | TPPs (Units) installed after 31st December 2003 and upto 31st December 2016                      | TPPs (Units) to be commissioned after 01.01.2017   |
|---------------------------|--------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------|----------------------------------------------------|
| Particulate Matter        | 100 mg/Nm3                                                                                       | 50 mg/Nm3                                                                                        | 30 mg/Nm3                                          |
| Sulphur Di- oxide (SO 2 ) | 600 mg/Nm3 for units less than 500 MW capacity 200 mg/Nm3 for units of 500 MW and above capacity | 600 mg/Nm3 for units less than 500 MW capacity 200 mg/Nm3 for units of 500 MW and above capacity | 100 mg/Nm3                                         |
| Oxides of Nitrogen (NOx)  | 600 mg/Nm3                                                                                       | 300 mg/Nm3                                                                                       | 100 mg/Nm3                                         |
| Mercury (Hg)              | 0.03 mg/Nm3 for units having capacity of 500 MW and above                                        | 0.03 mg/Nm3                                                                                      | 0.03 mg/Nm3                                        |

..........2.

(c) & (d) : The  installation  of  environmental  control  systems  is  capital  intensive  and also involve additional O&M expenditure. Some existing old coal based plants may not be able to meet the new parameters for various reasons, such as, lack of required space for installing  pollution  control  equipments  and  non-availability  of  suitable  technology  for Indian coal and may be required to be phased out over a period of time.
