A legal challenge could place the development of two multi-million pound liquified natural gas terminals in Pembrokeshire in jeopardy.

The pressure group, Safe Haven, has instructed solicitors to look into the possibility of seeking a judicial review in the High Court.

The challenge could also be taken a step further to the European Court.

Made up of local residents, business people and professionals, the group has researched the safety issues of LNG worldwide.

It has raised major concerns over the Dragon LNG project at Waterston and South Hook project at Milford Haven.

Said spokesman Gordon Main: "Safe Haven has been forced into a position where lawyers are now involved. We didn't want to face our elected representatives and civil servants across a court of law. We wanted them to stand shoulder to shoulder with us in our call for public safety to be put first."

He added: "It's not clear whether Safe Haven as a group, or one individual, will be progressing this. We are waiting for final advice.

"The aim is to challenge Pembrokeshire County Council over its decision to give planning consent for the two projects.

"We are proceeding as quickly as possible as we feel it would be irresponsible to allow the companies to spend millions only to find it was money wasted.

"We are also looking at the completeness of the environmental statements provided by both companies initially, and also how the Health and Safety Executive has absolved itself from carrying out a full quantitative risk assessment on the marine side, especially of tankers at the jetty and LNG shipping movements in the waterway," said Mr Main.

Any challenge in the European Court would be on the basis of whether the companies had fulfilled the European directive in terms of how active their environmental statements were.

The pressure group Safe Haven has denied that it is 'scaremongering' over the LNG issue. The group insists: "We have passed on information from level-headed scientists, experienced professionals, local experts and local pilots."
