Heavy fuel leaked from a power station in Manipur’s Imphal West district and spilled into streams flowing alongside it, officials said on Thursday.
The incident happened on Wednesday night at the Leimakhong power station. Streams passing through villages such as Kanto Sabal and Sekmai were affected by the spill, they said.
These streams meet the Imphal river — the lifeline of the region — downstream, they added.
The Chief Minister’s Office (CMO) directed the departments concerned to take “immediate necessary action to prevent an environment calamity, making use of all available resources in terms of machinery, manpower and expertise”.
