asked the Minister of Fuel and Power when a screening plant for opencast coal installed by his Ministry at Chatterley near Tunstall in Staffordshire became operational; how many tons of opencast coal have since been screened; and what was the total cost of installation.

The nearest opencast screening plant to Chatterley is at Diglake, four miles away, which started operating in November, 1946, and has so far screened 145,000 tons of opencast coal. The cost of installation was £16, 800.
