Regulation 25 Revocation and modification of authorisations
Subject to paragraphs (2) and (4), the Welsh Ministers may at any time modify or revoke an authorisation under regulation 22.
Subject to paragraph (3) the Welsh Ministers must not revoke or modify an authorisation under regulation 22 without giving at least 6 months' notice in writing of their intention to do so to—
the relevant supplier to which the authorisation relates;
any other relevant supplier which, for the purposes of supplying water to consumers, uses the water supply zone in respect of which the authorised departure has been given;
every appropriate local authority;
the Public Health Wales National Health Service Trust;
where the authorisation relates to a water supply zone which is wholly or partly in England, Public Health England ; and
the Council.
The Welsh Ministers may revoke or vary an authorisation under regulation 22 without notice if it appears to the Welsh Ministers that immediate revocation or modification is required in the interests of public health.
A relevant supplier on whose application a departure has been authorised under this Part must notify the Welsh Ministers as soon as the circumstances which gave rise to the application cease to exist; and the Welsh Ministers will thereupon revoke the authorisation without the need for prior notice.
