Attacking the five grounds cited in the closure order, he said Sterlite’s failure to furnish the ground water analysis report despite Tamil Nadu Pollution Control Board (TNPCB) holding such an analysis, sounded illogical and seemed that TNPCB is fishing out reasons to support Sterlite’s closure order. Speaking on failure to remove copper slag stored along the river Uppar and not constructing a physical barrier between the river and the slag, Aryama Sundaram, said it was never the TNPCB’s case that copper slag was a pollutant until the matter reached the NGT. He submitted that the reason for TNPCB directing the removal of copper slag was that it stopped water flow and not viewed as a pollutant. On the ground cited by TNPCB that Sterlite did not have Hazardous Waste authorization, Sundaram argued that it is TNPCB, that is sitting over their application for renewal of Hazardous Waste authorisation. Further hearing of the case is scheduled on July 4.
