HC Deb 20 July 1970 vol 804 cc30-1W
111. Sir T. Beamish

asked the Minister of Transport which types of ground rock salt are most effective for clearing ice and snow from roads in winter; what are the sources of supply, and the average cost per ton; by how much he estimates that domestic supplies will fall short of anticipated demand next winter; what is the reason for this shortfall and the prospect of making it good in future years; and what will be the cost of covering it by overseas purchases.

Mr. Michael Heseltine

Salt complying with British Standard Specification 3247/1 is recommended. The main source of supply is a Cheshire mine, where output is being raised. Increased demand has caused a temporary shortage which, if next winter is severe, could be about 0.3 million tons. But it could be met by imported salt costing £4-£7 per ton compared with £4 10s. for home salt.
