"My specific case is that the entire matter is politically motivated. There were no complaints (of alleged leakage) before and after that day (March 23, 2013).
"Every contemporaneous report, including that of the District Collector, said there was nothing wrong with our unit," senior advocate C A Sundaram, appearing for Sterlite, claimed.
After hearing Sterlite's arguments against the closure of its plant by the Tamil Nadu Pollution Control Board (TNPCB), a bench headed by NGT Chairperson Justice Swatanter Kumar directed the TNPCB to submit before it by May 20 the reasons for shutting down the smelting unit.
During the hearing, Sundaram argued that Sterlite has invested over Rs 4,000 crore in the copper smelting plant and the same was evident from the state-of-the-art scrubbing system installed (for cleaning the emissions) in the unit.
Sundaram argued that according to the complaints received from 12 individuals and three organisations, residents of Tuticorin town were affected by the alleged gas leak between 5.45 AM and 7 AM on March 23 from the Sterlite plant despite presence of several other units in the same industrial estate.
