Environment Protection Act 1986
Also: EPA 1986, Environment (Protection) Act

Background and evolution
India already had laws on water (1974) and air (1981) pollution when, on the night of 2–3 December 1984, methyl isocyanate gas leaked from the Union Carbide pesticide plant at Bhopal and killed thousands of people. The disaster exposed gaps in the regulation of hazardous industries: there was no single authority with clear powers to set standards across all media, inspect plants or act quickly. Parliament responded with the Environment (Protection) Act, which came into force in November 1986.
The constitutional basis is Article 253, which allows Parliament to make laws to implement international agreements and decisions. The preamble of the Act refers to the decisions taken at the United Nations Conference on the Human Environment held at Stockholm in June 1972, in which India participated. The 42nd Amendment (1976) had already added Article 48A, a Directive Principle on protecting the environment, and Article 51A(g), a Fundamental Duty to protect nature.
