HC Deb 28 April 1971 vol 816 c99W
5. Mr. Greville Janner

asked the Secretary of State for the Environment whether he will now seek powers to impose additional restrictions on pollution of the air through dust and filth emanating from foundries.

Mr. Peter Walker

I do not need further powers. However, I am awaiting a report from the National Industrial Fuel Efficiency Service on emissions from various individual processes including foundries, and in the light of this I shall decide whether to make further use of my powers under Section 2 of the Clean Air Act, 1968.
