In response to concerns that trade effluent discharged into the Tapi estuary in Surat district from its steel plants at Hazira was causing pollution above permissible limits, Arcelor-Mittal Nippon Steel India (AM/NS) has announced a Rs 2.73 billion investment in zero liquid discharge. The Gujarat High Court (HC) recently appointed the Indian Institute of Technology Gandhinagar (IIT-Gn) as a court commissioner to determine whether or not trade effluent discharged from AM/NS was causing pollution above permissible limits.
The court acted in response to a public interest lawsuit filed by Surat-based environmental engineer Roshni Patel, who claimed that the steel plant was discharging effluent into the river without properly treating it, causing harm to life in the estuary.
