Erode,May 18 (PTI) Seventeen textile dyeing units in SIPCOT Industrial Growth Centre at Perundurai stopped operations after the 90-day time limit granted by the Pollution Control Board lapsed on Wednesday, PCB officials said today. An official said 18 months ago, PCB had ordered the closure of the 17 textile units for “flouting” PCB rules. They approached the court and on its direction, they approached the PCB who granted 90 days time to enable them fulfil pollution control norms. Claiming that they have fulfilled PCB norms, Textile unit sources said they will again approach PCB seeking a permanent license to start operations. Meanwhile, it was stated that the PCB will monitor the pollution level periodically and criminal action would be taken for any violations like discharge of untreated effluents into water bodies.
