HC Deb 18 July 1977 vol 935 c335W
Mr. Hooley

asked the Secretary of State for Energy if he will give a general direction to the National Coal Board to promote the use of spoil heaps in the provision of hard core for roads in the place of high grade limestone.

Mr. Eadie

No. The National Coal Board's Minestone Executive already seeks the maximum outlets for colliery spoil for use as aggregate.
