§ Mr. Coulsonasked the Minister of Housing and Local Government and Minister for Welsh Affairs whether the Chief Alkali Inspector is now in a position to report on the effect of a new hot blast cupola in cutting down air pollution in Hull, details of which are contained in correspondence between the Parliamentary Secretary and the hon. Member for Kingston-upon-Hull, North, dated 14th June, 1961; and if he will make a statement.
§ Mr. RipponThere has unfortunately been delay in delivery of the electrical precipitator for installation on the cupola my hon. Friend has in mind. The precipitator is not now expected to come into operation until the spring. It will then be some months before its effectiveness can be assessed.
