Before commencement of any work set out in Schedule 1 to divert any apparatus the undertaker will provide Anglian Water with a schedule of apparatus which will be diverted as part of the authorised development setting out for each piece of apparatus whether those works are to be undertaken under this Schedule or under the 1991 Act and, where a diversion is to be carried out partly under this Schedule and partly under the 1991 Act, details of which part of the diversion is to be carried out under which power.

The undertaker may from time to time provide to Anglian Water amendments to the schedule referred to in sub-paragraph (1).

No amendment may be submitted under sub-paragraph (2) in respect of apparatus which is to be diverted as part of a work set out in Schedule 1, or which comprises such a work, after that work has commenced.
