The Environment (Protection) Act, 1986 (EPA) is an Act of the Parliament of India, serving as an "umbrella" legislation for environmental governance. It was enacted in May 1986 and came into force on November 19, 1986. The Act's origin lies in India's commitment at the United Nations Conference on the Human Environment held in Stockholm in June 1972, and it was passed under Article 253 of the Constitution to implement these international decisions. The immediate catalyst for its comprehensive nature was the 1984 Bhopal Gas Tragedy, which exposed the need for a unified law to manage hazardous substances and fill regulatory gaps left by existing sector-specific laws like the Water (Prevention and Control of Pollution) Act, 1974 and the Air (Prevention and Control of Pollution) Act, 1981.
The EPA, which has 26 sections and 4 chapters, works by granting the Central Government extensive powers under Chapter II, including the authority to take all necessary measures to protect and improve the environment (Section 3) and to issue binding directions (Section 5). It mandates that no person shall discharge environmental pollutants in excess of prescribed standards (Section 7) and requires procedural safeguards for handling hazardous substances (Section 8).
The Act connects to the constitutional principles of environmental protection found in Article 48A and Article 51A(g). A significant recent change occurred with the Jan Vishwas (Amendment of Provisions) Act, 2023, which aimed to decriminalize minor offences. This amendment removed the provision for imprisonment (previously up to five years under the original Section 15) for many contraventions. Instead, for violations of Section 7 or Section 8, the newly inserted Section 14A now prescribes a monetary penalty of not less than Rs. One lakh but which may extend to Rs. 15 Lakhs.
