| Air (Prevention and Control of Pollution) Amendment Act, 1987 | 1987 | This amendment introduced significant changes to the original 1981 Act. It enhanced the powers of the Central and State Pollution Control Boards, making them more effective in enforcing air quality standards. Notably, it empowered the CPCB to issue directions to SPCBs and also allowed the Central Government to issue directions to the CPCB. It also increased penalties for non-compliance, making the Act more stringent. Furthermore, it included 'noise' within the definition of 'air pollutant', recognizing noise pollution as a form of air pollution. | Strengthened the regulatory and enforcement capabilities of pollution control boards, provided the Central Government with greater oversight, and broadened the scope of air pollution to include noise, reflecting an evolving understanding of environmental hazards. This amendment made the Act a more formidable tool for pollution control. |
| Environment (Protection) Amendment Rules, 2018 (related to emission standards) | 2018 | While not an amendment to the Air Act itself, the Environment (Protection) Rules, 1986, under the EPA, are frequently amended to update emission standards for various sectors. A significant set of amendments in 2018 and subsequent years focused on tightening emission norms for thermal power plants, brick kilns, and other industries. These amendments often specify new limits for particulate matter, SOx, and NOx, aligning with the government's commitment to improve air quality and meet international obligations. | Led to stricter emission controls for major industrial polluters, pushing industries to adopt cleaner technologies and processes. This has a direct impact on reducing ambient air pollution levels, particularly in industrial clusters and urban areas, and is crucial for achieving targets under initiatives like the National Clean Air Programme. |
