Emission of sulphur dioxide from the Sterlite factory in Tuticorin above the permissible level led to people complaining about the plant, Environment Minister M.C. Sampath told the Assembly on Tuesday.
Replying to a calling attention motion, the Minister said continuous monitoring of sulphur dioxide by the Tamil Nadu Pollution Control Board (TNPCB) had clearly proved increased emission of gas from the plant on March 23, 2013.
He said people from Meelavittan, Anna Nagar, Brian Nagar, George Road and Thivipuram had complained of irritation in eyes, constant cough and choked throat condition and made a representation to the district Collector. Subsequently the Collector asked the district environmental engineer to take immediate action.
Mr. Sampath said according to National Institute of Occupational Safety and Health (NIOH) if the level of sulphur dioxide exceeded 5 parts per million (ppm), it would cause health hazards including eye irritation, cough and choked throat condition.
When the company was asked to explain about the emission of Sulphur dioxide above the permission level, it had informed the Pollution Control Board that the online continuous sulphur dioxide stack monitor was under maintenance. But it had failed to inform the TPCB about temporary suspension of monitor and resuming its operations.
The Minister said while issuing orders for closing the copper smelter division TNPC also directed termination of power supply to the plant.
The company approached the Green Bench and the Bench in its interim order had directed constitution of two-member expert committee.
The names of the experts would be announced on April 18 and the report would be submitted on 29 of the month, the bench had said.
