The main point was also to around the definition of air pollutants to include noise also. There is thus also Air (Pollution and Control of Pollution) amendment act 1987.
The water (Prevention and Control of Pollution) act 1974 was also awarded in 1988. An important amendment was to rename the Central/State Pollution Control Boards as boards also deal with air pollution some more powers were given to CPCB. The boards have been given powers to close or stop supply of water and electricity to offending establishments.
