The Port of Dover says millions of pounds of investment and hundreds of jobs will be at risk if it can't dredge the material it wants from the Goodwin Sands.
The work will help expand the Western Docks and the port says getting sand from further away will massively increase the carbon footprint of the project.
Opponents of the scheme say they will ask for a judicial review if the Government does give the go-ahead later this year.

The UK Coastguard are calling on people to stay safe after a number of incidents in the Dover area.
They are offering simple tips which will allow everyone to enjoy the coastline but reduce the risk of getting into a dangerous situation.
Advice such as wrapping up warm, wearing appropriate footwear, not running on cliff top paths and having a good phone signal are on the list. Also checking the tides and weather forecast before going out is essential.
It’s easy to get caught up in enjoying time on the beach or exploring coastal areas but make sure you keep a careful eye on the sea which can easily catch out even people with extensive knowledge of tides.
