Chhattisgarh government has filed a petition in the Supreme Court seeking its directions to restrain Andhra Pradesh from continuing construction of a dam on river Godavari at Polavaram. In its petition, Chhattisgarh government said that the clearances given to the project are illegal and the project threatens the environment and tribals of the state. Chhattisgarh is the second state after Orissa to move the apex court against the Polavaram project by AP government. Chhattisgarh government contended that around 2015.52 hectares of land falling in South Bastar, Dantewada in Chhattisgarh will be submerged by the dam and the environment clearances were given to the project without conducting public hearings in the area.
