This Order brings certain provisions of the Control of Pollution Act 1974 into force on 12th December, 1974. Sections 43 and 44 relate to the discharge of trade effluent to public sewers and provide for the application of full control under the Public Health (Drainage of Trade Premises) Act 1937 and the Public Health Act 1961 to certain discharges for which consent has not previously been required. The sections will not take effect for this purpose until a day to be appointed by order under section 44(5), but there is provision in section 43(2) for the automatic grant on that day of deemed consent for a previously exempt discharge, entitlement to which is conditional on the giving of notice about the discharge to the water authority within the period of 6 months beginning with the date of the passing of the Act (i.e. 31st July, 1974).
