OSPCB asks NTPC to shut down four power generation units

Bhubaneswar: Accusing it of failing to properly implement fly ash management measures, Orissa State Pollution Control Board (OSPCB) has asked the National Thermal Power Corporation (NTPC) to shut down its four power generation units at Talcher Super Thermal Power Station (TSTPS) at Kaniha in Angul district.

OSPCB`s action came after its scientists took stock of the actions taken by the NTPC after an ash pond breach incident on June 3.

"We have issued closure notice to four power generating units at TSTPS. Notice was served as the company failed to properly dispose its ash being generated from its six units," Sidhant Das, Member Secretary of OSPCB, said.

Meanwhile, a delegation of NTPC today met the OSPCB member secretary seeking some time for putting in place the appropriate fly ash management measure.

The NTPC executives, however, refused to comment.

The TSTPS generates about six lakh tonne fly ash every month. A three-member technical committee of the board had inspected the ash pond after the breach and advised NTPC to reduce generation and make alternative source of discharge.

The pollution control board had given them three choices – raising dyke of ash pond, disposal of ash in the form of high density slurry and transportation of ash through pipeline into a mining void.

The TSTPS discharges about six lakh metric tonne of ash every month, pollution control board sources said.

NTPC generates 500 MW each of electricity from the four power generating units.
