PowerGas is considering an appeal against a $1.5 million fine imposed on them by authorities for a gas leak in Jurong Island last April.

In a statement to the media on Wednesday, a spokesman said, "We disagree with the decision and we are considering filing an appeal under the Gas Act." She added that it was not appropriate to comment futher at this stage .

PowerGas is part of the Singapore Power Group and runs Singapore's gas transmission and distribution networks.

According to investigations conducted by the Energy Market Authority, a statutory board, the high pressure gas pipeline was damaged on April 23 last year. A contractor carrying out tunnelling works on the island had used an outdated gas pipeline plan provided by PowerGas, it said. It added that the hefty penalty was meted out as the incident could have resulted in very serious consequences to public safety and system security (and also) disrupted the gas supply to several users on Jurong Island.
