HC Deb 01 May 1973 vol 855 cc271-2W
Mr. Peter Archer

asked the Secretary of State for the Environment what working parties are now sitting to consider aspects of grit, dust and smoke emission, and in respect of each, when he expects to receive the report.

Mr. Eldon Griffiths

The information is as follows. First, a working party to advise upon the levels of emission admissible under Section 2 of the Clean Air Act 1968 in relation to incinerators and to furnaces where the material being heated contributes to the emission. Secondly, a working party to review the publication "Chimney Heights", which gives guidance to local authorities in exercising under the Clean Air Acts their statutory powers of control over the heights of new chimneys. The reports of both working parties are expected towards the end of this year.
