In its order on Saturday setting aside the Tamil Nadu government’s order on the closure of Sterlite’s copper smelter in Thoothukudi, the National Green Tribunal (NGT) said, “In the present case, TNPCB has adopted a hyper technical approach unmindful of object of law.” So long as establishment is complying with the pollution control norms and is willing to take further precautionary steps, the pollution control boards cannot arbitrarily close such establishments on hyper technicalities, as has been done in the present case. We expect TNPCB to have more focused and professional approach in performing its regulatory functions,” the NGT verdict.The NGT also directed Sterlite Copper’s parent Vedanta to utilise Rs. 100 crore, over the next three years, for the “welfare of the inhabitants” of Thoothukudi.During the hearing on December 7, Vedanta had informed the green panel that it was willing to invest Rs. 100 crore, apart from its investment of Rs. 10 crore per annum on Corporate Social Responsibility (CSR) projects.
