HC Deb 14 June 1973 vol 857 c380W
Mr. John

asked the Secretary of State for Wales if he will specify and identify the quarries, tips and other areas in South Wales known by him to have had toxic wastes Or chemicals tipped in or upon them.

Mr. Peter Thomas

A review of waste disposal sites in both England and Wales is proceeding, but it is not yet sufficiently complete for detailed information to be available. I am reminding local authorities of the importance of completing their surveys as soon as possible.
