The concept of Pollution & Waste in India is a regulatory framework established by a series of legislative acts and rules. It is defined by the Environment (Protection) Act, 1986 (EPA) as the presence of any solid, liquid, or gaseous substance in a concentration that may be injurious to the environment.
The legal structure began with the Water (Prevention and Control of Pollution) Act, 1974, which was India's first major pollution law, enacted to control the pollution of rivers and lakes following the 1972 United Nations Conference on the Human Environment. This Act established the institutional backbone: the Central Pollution Control Board (CPCB) and State Pollution Control Boards (SPCBs). The Air (Prevention and Control of Pollution) Act, 1981 extended the Boards' authority to air quality. The comprehensive EPA, 1986, passed after the Bhopal gas leak under Article 253 of the Constitution, serves as the umbrella legislation, granting the Central Government broad powers to set national standards and regulate hazardous substances.
The mechanism works through the CPCB and SPCBs, which set standards, inspect, and enforce compliance. Under the Water Act, 1974, industries must obtain Consent to Establish and Consent to Operate (Sections 25 & 26) before discharging effluents. The framework connects to specific rules like the Solid Waste Management Rules, 2016 and the Plastic Waste Management Rules, 2016. A key concept is Extended Producer Responsibility (EPR), which mandates that producers, importers, and brand owners are responsible for the collection and disposal of their product waste.
The framework is constantly evolving; for instance, the Plastic Waste Management Rules, 2016 were amended in 2022 to introduce mandatory EPR targets and again in 2024 to set stricter criteria for biodegradable plastics. Furthermore, a proposed amendment to the Water Act, 1974 in 2024 aims to decriminalize minor offenses, replacing jail terms with monetary penalties ranging from ₹10,000 to ₹15 lakh.
