AMMONIA RELEASE FROM ORICA'S KOORAGANG ISLAND PLANT

9 November 2011

Orica has confirmed that there was a release of ammonia from its Kooragang Island plant this afternoon.

Initial investigations indicate that the release occurred from an ammonia tank when a relief valve opened in response to pressure within the tank. There were three releases of approximately one minute each over a 45 minute period.

The ammonia vapour travelled across the Hunter River to the Australian Rail Track Corporation Facility where the odour was detected and Emergency Services were called.

The Environmental Protection Agency and other regulatory bodies have been notified.

The incident is currently under investigation and Orica will provide further information as it becomes available.
