The law gives blanket powers to the environment ministry to take emergency and long-term steps to tackle any kind of environmental pollution.
Section 5 of the Environment Protection Act, 1986 states: “Notwithstanding anything contained in any other law but subject to the provisions of this Act, the Central Government may, in the exercise of its powers and performance of its functions under this Act, issue directions in writing to any person, officer or any authority and such person, officer or authority shall be bound to comply with such direction.”
These powers extend to closing, prohibiting or regulating any industry, operation or process. The ministry has, in fact, exercised these powers in the past, shutting down factories and other projects to avoid water, air and soil pollution, although, more often than not, it has done so on the directions of the courts. For maintaining national air quality standards in the cities, however, government has not taken such measures yet.
