The Secretary of State may for the purposes of paragraph 4 make a class approval of arrangements relating to the ancillary matters referred to in paragraph 4(2)(a), (b) and (d) to (g) above.

A class approval may make different provision for different cases.

Before making a class approval the Secretary of State must consult the planning authorities who would be affected by it.

Where arrangements made by the nominated undertaker are approved under a class approval, they do not require the approval of the relevant planning authority under paragraph 4.

But the nominated undertaker may in the case of any particular arrangements request approval under paragraph 4.

If the relevant planning authority to which such a request is made considers that the circumstances of the case justify it, the authority may grant approval under paragraph 4 (and, accordingly, the arrangements are subject to that approval instead of the class approval).

A class approval may be varied or revoked.
