Minister, may I ask for a statement from the Minister for Climate Change regarding the historic dumping of toxic waste at Ty Llwyd quarry at Ynysddu? Caerphilly County Borough Council is now the owner of the site, having compulsorily purchased the quarry, but has refused to register Ty Llwyd as contaminated land in spite of local concern about leachate leaking out and polluting neighbourhood properties as well as the roads. Natural Resources Wales confirms it is solely the council's responsibility to register contaminated land, but Caerphilly CBC maintains that the leachate does not flow from its property. Will you join me in supporting the residents, Minister, and local councillors Jan Jones and Janine Reed, in calling for a public inquiry to be held into the potential threat to neighbouring land and the River Sirhowy from the leaking of harmful substances from Ty Llwyd quarry? Thank you.
