Case Note & Summary
The case involved a series of civil appeals arising from orders of the National Green Tribunal (NGT) concerning the disposal and utilization of fly ash by thermal power plants. The NGT had issued several orders, including directives for the evacuation of fly ash and compliance deadlines, which were challenged by M/s Aravali Power Co Pvt Ltd. The core issue was whether the NGT's orders were valid given subsequent notifications from the Ministry of Environment and Forest and Climate Change (MoEF&CC) that altered compliance requirements. The Supreme Court noted that the NGT had found thermal power plants non-compliant with earlier notifications, which mandated 100% utilization of fly ash by a specified date. However, a new notification issued on 31 December 2021 established new parameters for ash utilization, effectively superseding the previous notifications. The Court held that the NGT's orders were fundamentally altered by this new regulatory framework, leading to the conclusion that the NGT's findings were no longer applicable. The Supreme Court set aside the NGT's orders and directed the MoEF&CC to ensure compliance with the new notification's provisions, emphasizing the need for environmental safeguards in the disposal of fly ash. The judgment clarified that it did not address the merits of the new notification, allowing parties to seek remedies if aggrieved by its terms. The appeals were disposed of in accordance with these directions.
