HC Deb 15 March 1978 vol 946 c262W
Mr. Skeet

asked the Secretary of State for the Environment what information is available to him of the reserves of sand and gravel available on the United Kingdom Continental Shelf; and how these compare with the reserves available on land.

Mr. Marks

Accurate information on the tonnage of reserves of sand and gravel in areas licensed for dredging on the Continental Shelf is not available. Recent information about land with the benefit of planning permission for the extraction of sand and gravel suggest that reserves may amount to 1,200 million tonnes.
