KUALA KANGSAR: Tenaga Nasional Bhd (TNB) has confirmed that an oil spill at the Sultan Azlan Shah (Bersia) power station in Gerik last Saturday was, in fact, a leakage.
Its Sungai Perak power stations generation division general manager Mazlan Mohd Som said the situation is under control after repair and cleanup work carried out on Wednesday.
"Oil leaked into the river water due to the leakage in one of the hydraulic systems at the power station.
"We searched for the source of the leakage on Monday and once we were able to mobilise our spill team, we employed a containment boom to prevent further contamination and used oil dispersants to break up the oil in the water," he told reporters during the launching of the flood siren system for the Chenderoh dam at Kampung Chegar Galah Jetty near here on Thursday.
The system was launched by Perak Mentri Besar Datuk Seri Dr Zambry Abd Kadir.
Mazlan said the spill team checked the scene of the incident Wednesday evening and found no oil spots in the water.
"It was not a major oil spill. Thankfully, we were able to take mitigation measures.
"We have also reported the incident to the Department of the Environment as well as the Gerik assemblyman," he said.
Asked for further measures to prevent a recurrence of the incident, Mazlan said TNB is upgrading the hydraulic system at the Bersia power station to one that is oil-free.
"Until then, we will change the type of oil used to a biodegradable one, so that if another leakage happens, it will not harm the environment," he said.
