SAMBALPUR: The Central Pollution Control Board (CPCB) has ordered immediate closure of Shyam Metalics & Energy Limited’s plant at Rengali here for serious and repeated environmental violations, invoking powers under section 5 of the Environment (Protection) Act, 1986.
The action follows multiple inspections and directions issued in May 2025, which the company reportedly failed to comply with. A fresh inspection carried out on March 17 and 18 this year revealed widespread non-compliance across air pollution control, wastewater management, hazardous waste handling and regulatory approvals, prompting the central regulator to issue the order for closure.
According to the official order, particulate matter emissions from key stacks were found to be significantly above permissible limits, with readings as high as 268 mg/Nm³ against the prescribed standard of 50 mg/Nm³. The inspection team also observed the absence of adequate fume extraction systems and non-functional pollution control equipment in several units, resulting in uncontrolled emissions and fugitive dust.
Serious lapses were also reported in water and effluent management. Despite a mandated zero liquid discharge (ZLD) system, inspectors found evidence of wastewater flowing through drains leading outside the plant boundary, including bypass channels and a damaged wall allegedly used for discharge diversion. The plant was also found operating without a functional sewage treatment plant as required under consent conditions.
The CPCB further flagged improper handling of hazardous waste, including open storage of tarry residues and oil-contaminated materials without safeguards, posing risks to soil and groundwater. Over 50 drums of hazardous waste were found stored in the open without labelling or containment.
In addition, the unit was found operating certain facilities without required approvals, including an unauthorised slag crushing plant and altered emission configurations. It had also failed to submit mandatory environmental reports, including the annual ash audit.
The CPCB has directed that the plant shall not resume operations without prior approval and full compliance with environmental norms. The company has been asked to submit a compliance report within 30 days, failing which further legal action may be initiated.
