Answered on 12 September 2018
(a) Flaring is an essential process for safe operations of a gas plant and is normal industry practice. On the day in question, 2 August 2018, flaring commenced at approximately 9:43am.
(b) There were two flaring events on the same day associated with the plant outage, lasting approximately four hours and one hour respectively.
(c) The two flaring events resulted in approximately 270 tonnes of CO2-e being released.
(d) Flaring results in the release of atmospheric emissions associated with the combustion of gas. The dark smoke generated during this event was a result of propane being flared from the compressor circuit.
(e) This flaring event was required as a result of an unplanned production outage. This de-pressurisation is a critical safety control.
