Hyder Consulting (UK) Limited of Centre Park, Warrington, has lodged a "Scoping opinion for the storage of gas" off the riverbank near Stalmine, with Lancashire County Council.
Brief details of the document appeared on Wyre Council's website today, and a detailed copy is expected to be available on the council's website by Tuesday.
Despite the document being on Wyre's planning applications list, a council spokeswoman said it was not a planning application.
A "scoping application" is one made to a council by would-be developers requesting an opinion about what information should be included within an environmental impact assessment.
Canatxx's previous bid to store gas under the Wyre estuary led to a long-running battle between the company and environmental protestors on both sides of the River Wyre.
After a public inquiry the government threw out Canatxx's plans, but earlier this year Canatxx - to the surprise of many of its critics - announced it would be submitting fresh plans in autumn 2008.
Both Lancashire and Wyre opposed Canatxx's last application for gas storage in specially drilled out salt caverns under the estuary.
Canatxx has been successful in obtaining planning permission for an LNG base for its other big energy scheme in North Wales.
Canatxx's Welsh plan will involve the construction of an offshore platform almost two miles off Amlwych, Anglesey.
Gas-carrying tankers from South America, Russia and the Middle East will have their cargo sent to an LNG plant at Amlwych, where it would be be converted to natural gas before being sent via a 70 mile pipeline under the Irish Sea to the Over Wyre coast and on, through another pipe under Over Wyre to the national gas grid connector at Nateby.
Whereabouts on the coastline or riverbank the Caxnatxx pipeline will come ashore has yet to be revealed.
Anglesey county councillors approved Canatxx's LNG plan after hearing that Health and Safety Executive had concluded that the risks of an accident at were so small that there were no significant reasons for refusing the application on safety grounds.
