Spearing said he “couldn’t be prouder of the team”, adding: “Not only did volunteers give up their time to take part in this operation and work safely in such difficult terrain, but throughout the day we also responded to four separate mountain rescue callouts.

“That commitment says everything about the professionalism and dedication of our volunteers.”

Although legally the financial responsibility of clearing fly-tipped waste on private property falls on the landowner, the council said it stepped in given the “exceptional danger and scale of the site”.

Council leader Ann Crimmings said: “The Bwlch Mountain is home to some of our most beautiful countryside, and it is completely unacceptable that a minority treat it as a personal dumping ground.”

She said similar fly-tipping behaviour in the future would “not be tolerated”.

“That is why we will continue to use all the powers available to us to hold those accountable for their actions,” she said, adding that many of the items recovered on Bwlch Mountain could have been taken to a recycling centre “or collected from the kerbside at no extra cost”.
