§ 48. Mrs. Fennerasked the Secretary of State for the Environment if he is satisfied that the present controls on cement dust emission are adequate; and if he will make a statement.
§ Mr. Eldon GriffithsI am satisfied that the Alkali Act, which requires that the best practicable means must be used to prevent emissions and to render them harmless where discharged, is the most effective basis of control, and that the Alkali and Clean Air Inspectorate is102W enforcing it properly. Emissions of cement dust in this country have fallen from well over 100,000 tons in 1962 to less than 40,000 tons in 1971, this despite a marked increase in cement production. I expect to see further improvements.
