Residents opposed to plans for a temporary asbestos storage site in County Antrim are seeking a judicial review to overturn the decision.
Campaigners are opposed to plans for an asbestos store
Crumlin residents will lodge papers for the review on Thursday after holding a meeting to gauge the level of support for continuing to oppose the plant.
The meeting, on Wednesday, was attended by South Antrim DUP MP William McCrea.
It is proposed that asbestos from all over the province will be taken to a collection site at Crosshill.
The government has said the plant will pose no risk to health, and gave plans for it the green light in March.
The proposal will see double bagged asbestos being transported to Crosshill by the firm Eastwood Ltd, where it will be stored in steel containers before it is moved on for final disposal in England.
However, objectors say they are taking the action because they believe the risk of contamination is too great.
