GLNG has applied to the Department of Environment and Science to amend the Environmental Authority (EA) that authorises operations at the GLNG Facility on Curtis Island.

The EA amendment application seeks to include clear limits on the frequency and duration of visible smoke allowed from the GLNG facility during maintenance, shutdowns and plant upsets.

The limits being applied for are consistent with those for similar LNG facilities operating in the region.

The EA amendment application is supported by air quality modelling which show that visible smoke released during flaring events does not adversely impact air quality in the region.

Clarity on flaring limits

To bring GLNG in line with other LNG facilities operating in the region, GLNG’s EA amendment application asks for visible smoke flaring to occur:

  • No more than 7 hours per annum; and
  • No more than 14 times per annum; and
  • No more than 30 minutes per flaring event but up to a maximum 90 minutes when a flaring event must be done during daylight to ensure the safety of workers and the safe operation of the GLNG facility

GLNG’s EA amendment application is not intended to increase the levels of flaring activity at the GLNG facility. Santos GLNG is continuously improving its operating procedures to safely reduce visible smoke flaring to the maximum extent possible.

You may make a submission about the application during the submission period, which is until 17 December 2020, inclusive. See the Public Notice for instructions on how to make a submission.

For enquiries about the application contact the community hotline on 1800 761 113 or via email at or the Department of Environment and Science on 1300 130 372.
