Revocation and modification of authorisations
24.—(1) Subject to paragraphs (2) and (3), the National Assembly for Wales may at any time modify or revoke an authorisation under regulation 20.
(2) The National Assembly for Wales shall not revoke or modify an authorisation under regulation 20 without giving at least six months' notice in writing of its intention to do so to—
(a)the water undertaker to which the authorisation relates;
(b)the appropriate local authority;
(c)the appropriate health authority; and
(d)the relevant customer services committee,
but it may revoke or modify an authorisation without notice if it appears to it that immediate revocation or modification is required in the interests of public health.
(3) A water undertaker on whose application a departure has been authorised under this Part shall notify the National Assembly for Wales as soon as the circumstances which gave rise to the application cease to exist; and the National Assembly for Wales shall thereupon revoke the authorisation without the need for prior notice.
