National Green Tribunal (NGT) imposed a fine of Rs. 50 crore on Delhi Govt. Aam Aadmi Party (AAP) for not taking action against steel pickling units in residential areas as they fall under the prohibited list of industrial activity as per as the Delhi Master Plan, 2021.

Pickling is the process of removing the impurities from the metals by using strong inorganic acids.

NGT Chairperson Adarsh Kumar Goel ordered the Delhi Govt. to immediately shut down the industrial units.

 A plea was filed by an NGO, All India Lokadhikaar Sangathan which demanded the immediate execution of the order by which green panel had directed the Delhi Pollution Control Committee (DPCC) to take action against stainless steel pickling industries in residential areas.

The plea also stated that such units functioning at Wazirpur discharged liquid waste in open drains which ultimately met the Yamuna river.
