Environment Minister Andrew Muir met local MLAs last week to discuss plans for the Mobuoy site at Campsie in County Londonderry.

The site was discovered in 2013 and contains an estimated 1.6 million tonnes of waste across more than 100 acres.

Investigations found 627,000 tonnes of that waste had been dumped illegally.

In June last year, Paul Doherty and Gerard Farmer were sentenced at Londonderry Crown Court for offences linked to the dumping.

The most recent cost estimate for remediation is £107 million, though officials have previously given a range between £17 million and £700 million.

SDLP MLA Mark H Durkan and Sinn Féin MLA Ciara Ferguson both said the meeting produced no new timeline or confirmed funding.

Muir stated after the meeting that work will now move towards a final remediation strategy and an updated cost estimate ahead of a formal business case.
