Actor Kamal Haasan on Friday voiced his concern on the environmental impact due to the dumping of the ash waste by power plants in river Kosasthalaiyar and also warned about possible flooding of north Chennai.

In a series of tweets, Haasan said that the Vallur Thermal Plant and North Chennai Thermal Plant are dumping their ash waste in the river, and cited expert opinion to warn that north Chennai would get flooded even during normal rains.

He also noted that the forecast now is more than normal rainfall which, in turn, puts at risk 10 lakh people in that area.

The actor said a good government should find a permanent solution for the problems faced by the people.

Haasan also warned the government and the people that it would be dangerous for Chennai if the Ennore Creek is ignored.

According to him, the government did not look at the issue when the environmentalists took up the issue of dumping of waste by the power plants, or when the local people also joined them.

In addition, Haasan alleged that Bharat Petroleum and Hindustan Petroleum have built their facilities in the river.

The actor also said he is hearing about attempts to encroach upon 1,000 acres under the guise of expansion of Kamarajar Port in Ennore, near here.
