JOHOR BARU: The Johor Department of Environment (DOE) has issued a stop work order to a chemical plant in Pasir Gudang, which was pinpointed as the source of a chemical stench which enveloped parts of northern Singapore on Monday.

DOE director Datuk Dr Mohammad Ezanni Mat Salleh said the order was issued after the plant suffered a fire at one of its facilities earlier this month.

"The order will be in effect until the plant completes necessary remedial actions. We will make sure that the plant complies with the order before allowing it to resume operations," he said.

It was reported on Friday that Singapore's National Environment Agency (NEA) traced the source of a chemical stench that cloaked the north-eastern part of the Republic on Sept 25 to an industrial facility in Pasir Gudang.

The agency was reported as saying that it contacted the DOE for assistance after the smell was detected by distressed residents on Monday.

"The DOE… has traced the source… and is taking action against the operator," the NEA said.

On Monday, residents in Sengkang and Punggol, Singapore complained of an acrid, chemical stench that was later detected in areas such as Ang Mo Kio, Yishun, Seletar and Bishan. Thick smoke also hung over some of the affected areas, residents said.
