HC Deb 28 July 1959 vol 610 c42W
72. Mr. Hastings

asked the Minister of Housing and Local Government and Minister for Welsh Affairs if he will introduce legislation to give local authorities power to designate sulphur-oxide-free zones, as well as smokeless zones, in the areas for which they are responsible

Mr. H. Brooke

T am afraid that in the present state of scientific and technical knowledge it would not be practicable to achieve arrangements on the lines contemplated by the hon. Member.
