Legal Precedents & Enforcement Framework

Judicial decisions establishing mandatory fly ash utilisation within 300 km of thermal plants.

Compliance position: The purpose of this page is to make the mandatory character of the applicable Gazette provisions clear. Where the notification applies, avoiding the prescribed use of ash-based products is not merely a commercial preference; it can constitute non-compliance with the applicable environmental notification.
