§ Mr. Coulsonasked the Minister of Housing and Local Government and Minister for Welsh Affairs what official report he has received on the working of the new plant at a factory in Staffordshire, referred to in his letter to the hon. Member for Kingston-upon-Hull, North, dated 18th May, 1960; and what conclusions he has drawn as to the effectiveness of such type of plant in reducing air pollution in the Hull area.
§ Sir K. JosephThe performance of the new waste gas plant at the Staffordshire works is being improved, but it is not yet operating to the Chief Alkali Inspector's satisfaction. It is therefore too early to judge how effective it might be if installed at works in Hull.
