§ Mr. D. E. Thomasasked the Secretary of State for the Environment if he will publish the literature survey related to stone quarries and the large-scale opencast working of non-ferrous metals and methods of extraction and waste disposal and rehabilitation on and after-use of worked out mining sites, undertaken for the Stevens Committee on Mineral Planning Control; and, if so, when.
§ Mr. OakesI assume that the hon. Member is referring to the studies into the environmental problems of large-scale opencast working of non-ferrous metals and stone quarries which have been undertaken for my Department by a research team at the Royal School of Mines, Imperial College. A report on this is expected to be published next year.
