Notes:
Certain functions of the Minister of Housing and Local Government were transferred to the Secretary of State for Wales by the Secretary of State for Wales and Minister of Land and Natural Resources Order 1965 (S.I. 1965/319, Article 2(1), Schedule 1) and the remaining functions of that Minister were transferred to the Secretary of State by the Secretary of State for the Environment Order 1970 (S.I. 1970/1681, Article 2(1)). References to “the Minister” and “the appropriate Minister” in the Clean Air Acts 1956 and 1968 are therefore reproduced in the Bill as references to the Secretary of State.
