HC Deb 03 March 1971 vol 812 c431W
53. Mr. Kelley

asked the Secretary of State for the Environment what steps have been taken to ensure the maximum use of colliery shale in the construction of the M18 on that stretch which is adjacent to Hatfield Colliery.

Mr. Michael Heseltine

Tenders for this work were invited on the basis of a specification broadened to permit the use of colliery shale suitable for road building and I understand that the contractor intends to use substantial quantities of it.
