The local government secretary needs more time to decide whether expansion plans at an oil site in East Yorkshire need a detailed environmental study.
Rathlin Energy wants to triple the width of the West Newton A site in Holderness, drill another six wells there and extract oil for 15-20 years.
East Riding of Yorkshire Council ruled that a planning application for the scheme did not need an environmental impact assessment.
But almost 30 representatives of local councils disagreed and asked the local government secretary, Robert Jenrick, to make his own ruling, known as a screening opinion.
Cllr Jacob Birch, a Conservative member of East Riding of Yorkshire Council, who wrote to Mr Jenrick, said today:
“I have had notification from the Secretary of State that they require further time before a decision regarding my discretionary screening opinion request can be issued.
“It will be around a further 10 days, hopefully by which point a decision should be issued.”
