Orica and the Environmental Protection Agency are investigating an ammonia leak that occurred at Orica’s Kooragang Island ammonia plant yesterday at approximately 1:15 pm.
AAP reports that a “plume of ammonia belched into the air from the vent stack of an Orica factory” at the site, which manufactures ammonium nitrate for mining as well as fertiliser products.
“Detectable levels of ammonia were reported at industrial sites to the west of the Orica facility,” said Orica in a statement, which also put the leak down to the lifting of a relief valve, which has since been reset.
“The relevant authorities were notified, including the NSW Environment Protection Authority (EPA) and NSW Fire and Rescue.”
The Newcastle Herald reported yesterday that outdoor staff were instructed to go indoors, with emergency worker staff summoned but not required.
