The Air (Prevention and Control of Pollution) Act of 1981 aims to control and reduce air pollution in India. It establishes central and state pollution control boards to regulate air quality standards. The boards monitor entities for compliance with emissions standards and can take legal action against violators or order operations to cease. Key features include giving the boards powers to declare air pollution control areas, require industries to obtain permission before operating in such areas, set emissions limits, conduct inspections and testing, and establish air quality laboratories. Non-compliance can result in fines and imprisonment. The Act contains 54 sections organized across 7 chapters delineating the roles and responsibilities of the pollution control boards.
