Quick Revision: The Madhya Pradesh High Court’s directive to the State Pollution Control Board to submit a report on mercury contamination in toxic waste ash underscores the judiciary’s role in enforcing the Precautionary Principle and Polluter Pays Principle in hazardous waste management.

Why is this in the news?

The Madhya Pradesh High Court has taken suo motu cognisance of allegations regarding the presence of mercury in the ash generated from the incineration of toxic waste originating from the Union Carbide India Limited (UCIL) facility in Bhopal. The Court has directed the State Pollution Control Board to submit a detailed report within seven days on the composition and disposal process of the ash, with a subsequent hearing scheduled for 15 October 2026. This development underscores the judiciary’s role in ensuring compliance with environmental safeguards and public health standards in hazardous waste management.

Background

• The Union Carbide India Limited (UCIL) facility in Bhopal was the site of the 1984 Bhopal Gas Tragedy, one of the world’s worst industrial disasters, resulting in thousands of deaths and long-term health impacts on survivors.
• Post-disaster, residual hazardous waste from the UCIL plant remained unaddressed for decades, posing ongoing environmental and health risks to local communities.
• In 2004, a Public Interest Litigation (PIL) was filed seeking the disposal of toxic waste from the UCIL site, leading to judicial intervention and subsequent directives for remediation.
• The toxic waste was eventually incinerated at a Treatment, Storage and Disposal Facility (TSDF) in Pithampur, District Dhar, Madhya Pradesh, raising concerns about the safety and environmental impact of the process.
• The present case emerged from concerns raised by intervenors regarding the potential contamination of local water supplies and the health risks to residents in nearby wards.
• The High Court’s intervention follows prior directives for independent testing of water samples and comprehensive environmental impact assessments.

What is the legal and environmental framework governing hazardous waste management in India?

• The Hazardous and Other Wastes (Management and Transboundary Movement) Rules, 2016, regulate the generation, storage, transport, treatment, and disposal of hazardous waste, including mercury-containing waste, under the Environment Protection Act, 1986.
• The National Green Tribunal (NGT), established under the National Green Tribunal Act, 2010, has jurisdiction over matters related to environmental protection, including hazardous waste disposal and pollution control.
• The Precautionary Principle, enshrined in Principle 15 of the Rio Declaration on Environment and Development, guides judicial and administrative actions to prevent environmental harm even in the absence of conclusive scientific evidence.
• The Polluter Pays Principle obligates industries responsible for pollution to bear the costs of remediation and compensation, ensuring accountability in environmental governance.
• Public Interest Litigations (PILs) serve as a mechanism for citizens to seek judicial intervention in cases of environmental degradation or public health threats, as demonstrated in the Union Carbide case.
• Mercury is a highly toxic heavy metal listed under Schedule I of the Hazardous Waste Rules, 2016, due to its persistence, bioaccumulation, and severe health impacts, including neurological and renal damage.
• The Environment Impact Assessment (EIA) Notification, 2006, requires prior environmental clearance for projects involving hazardous waste management, including incineration facilities.
