Householders fighting the reopening of a quarry near their homes claim Suffolk County Council has been negligent in its care of duty.
The quarry at Peyton Hall was recently sold by Tarmac to a private company based near Colchester.
It was last used nearly 30 years ago, and residents say they thought the site had been mothballed but the new owner has applied for permission to start extracting sand and gravel again.
The quarry was originally granted planning permission in 1951, and its licence to make extractions runs until 2024.
Plans to build a crushing plant were turned down in 2001.
George Ashford, of Cosford Road, is a member of The Aldham Tye and Ivy Tree Lane Residents’ Group.
He said: “We feel that, in its eagerness to discharge its legal obligations to the landowner, Suffolk County Council has neglected its duty of care to residents.
“Having initially stated that the site was mothballed, why didn’t the council make the public aware that there were plans to re-open it prior to the decision being made?
“While we understand this was a review of the conditions of an existing permission, rather than a planning application, we believe the county council has been remiss in its handling of the situation.”
The group is carrying out traffic surveys at the Aldham Mill Hill junction with the A1071. More than 40 lorries a week could be entering and exiting the quarry site.
Mr Ashford added: “Obviously the county council has a wider duty of care in relation to the public purse, and must do all it can to ensure the taxpayer is not exposed to a compensation claim from the landowner but I would argue that it is the taxpayer that will foot the bill when the Aldham Mill Hill/A1071 needs upgrading to ensure traffic safety.”
The residents have been promised a meeting with both the county council and the owner’s agents to discuss concerns.
