Disposal of Ash of Power Plant

As reported by Central Electricity Authority (CEA), out of 131.09 million tons of ash generated from the Thermal Power Plants in the country, 73.13 million tons was utilized during the year 2010-11. 

Water quantity of 4 to 5 times of the ash is required for handling the ash disposal. No release of toxic elements like mercury, arsenic, lead, cadmium, etc. to the environment has been brought to the notice of Central Electricity Authority. Moreover, Ministry of Environment and Forests stipulates lining of ash ponds at the time of environmental clearance of coal/lignite based thermal power projects so as to ensure that the ash water does not percolate and get mixed up with ground water. 

This information was given by the Minister of State for Power Shri K.C.Venugopal in a written reply to a question in Lok Sabha today.
