The Clean Air (Measurement of Grit and Dust from Furnaces) Regulations 1971
These Regulations re-enact the Clean Air (Measurement of Grit and Dust) Regulations 1968 which, under section 7 of the Clean Air Act 1956, prescribe the requirements to be observed in recording measurements of grit and dust emitted from certain furnaces. The provisions of that section have been considerably affected by the provisions of section 5 of the Clean Air Act 1968, and in particular the description of furnaces to which the Regulations can apply has been extended. (In some cases, however, the local authority can be asked to make and record the measurements.) The Regulations are now reenacted so that they will apply to the extended description of furnaces; and accordingly only minor amendments have been made in the text.
