The Plant is located in Korba district. The closure notice mentioned that ash slurry water from the damaged ash dam is polluting water of a Belgiri canal passing near the plant that drains into Hasdeo river.
Notably, Hasdeo river water is mostly used for irrigation and at some places for drinking purpose in the region.
A statement of the Board released in state capital said that action has been taken following collapse of a Ash Dam (Ash Dyke) resulting in thousand tonnes of ash slurry drained into Belgiri canal passing near the plant. The Environment Board has also asked BALCO management to repair the dam urgently.
The company has two plants with a capacity of 245,000 tonnes per annum (tpa) and 325,000 tpa. The first one is getting supply from the 540-Mw power station, another captive plant of Balco while the 1200-Mw plant now under the scanner is feeding the 325,000 tpa unit.
