Which of the following mechanisms can be used for reducing the emissio...
  1. In 2015, the Ministry of Environment, Forests and Climate Change (MoEFCC) notified specific standards for the thermal power plants to control the emissions under “Environment (Protection) Amendment Rules, 2015’. 
  2. As per rough estimates, the 2015 norms can reduce the TPPs’ PM emissions by 35%, SO2 emissions by 80%, and NOx emissions by 42% and reduce their water consumption by nearly a third.
  3. The norms provide different mechanisms to reduce the emissions and usage of water such as: 
    • Flue Gas Desulphurization (FGD) process for controlling SOx emissions. 
    • Selective Non-Catalytic Reduction (SNCR) and Selective Catalytic Reduction (SCR) system for controlling NOx emissions. 
    • Electro-Static Precipitators (ESPs) are to be deployed for control of particulate matter (PM) in thermal power stations. 
    • Installation of cooling towers in order to change over to a closed cooling water system for controlling water consumption. Hence option (a) is the correct answer.
