NGT Central Zone issued notices to the Principal Secretaries of Urban Development, Forest and Environment and to the District Collector of Kota along with the Kota Municipal Corporation and the Urban Improvement Trust.
They have been asked to respond by December 12.
Judicial member Justice Dalip Singh and expert member P S Rao issued these notices while admitting the petition filed by an environmentalist Babu Lal Jajoo.
"The aforesaid acts of omission and commission are resulting in destroying the eco-system of the river as well as polluting the river and thereby clearly violating the provisions of the Water (Prevention and Control of Pollution) Act, 1974," petitioner's counsel MS Kachhawa argued.
Another issue raised is the "unauthorised and excessive" fishing in the Chambal river, which is also adversely affecting the population of alligators, crocodiles and dolphins and other flora on the river's bank, which is unique to the eco-system of the river.
