HC Deb 08 November 1978 vol 957 c219W
24. Mr. Ron Thomas

asked the Secretary of State for the Environment if he is satisfied with the present regulations aimed at preventing the emission of dangerous chemicals into the atmosphere, especially in areas where there is a heavy concentration of chemical plants.

Mr. Denis Howell

Yes. Processes which give rise to emissions of dangerous substances, if they are difficult to control, are scheduled under the Alkali etc. Works Regulation Act 1906 and firms using these processes have to register with Her Majesty's Alkali and Clean Air Inspectorate. Firms are required to use the best practicable means for preventing the escape or discharge of noxious or offensive gases and for rendering harmless what is emitted.
