Gas and oil producer Santos is calling on the NSW government to mirror Queensland and set a timetable for the approvals process for its proposed coal seam gas project in the state’s north west.

The $3 billion project in Narrabri is still waiting for a determination on its environmental impact statement filed with the Department of Planning and Environment in 2017.

“I was really pleased to see the premier in Queensland requesting a timeline for Adani to get a decision and I think that’s what’s been lacking for us as well,” Santos chief executive Kevin Gallagher told The Australian on Monday.

“We would welcome a timeline being set so we know what we’re dealing with.”

Last week, the Queensland government pushed for and got a timeline for the approvals process for the controversial planned Carmichael coal mine in the Galilee Basin, with all decisions now expected to be finalised in June.
