New Delhi: The Delhi high court on Tuesday referred to National Green Tribunal (NGT) a batch of petitions alleging that noise pollution generated by aircrafts at the IGI airport is affecting health of the residents of nearby areas.

“Considering the provisions of the Environment Protection Act, the Environment Protection Rules and Noise Pollution (Regulation and Control) Rules as also the definition of noise pollutants given in the Air (Prevention and Control) of Pollution Act, it can hardly be disputed that these petitions involve a substantial question relating to environment,” said a bench of Chief Justice D Murugesan and Justice V K Jain.
