(1)  The Director may notify a person who, immediately before a licence document, in relation to an environmental licence granted under section 42E in relation to an activity, is issued to the person under section 42ZB , was carrying out an activity under an existing authorisation in relation to the activity –

(a) that the existing authorisation is void; or

(b) that a condition or restriction of an existing authorisation that, in the opinion of the Director, is inconsistent with a condition or restriction imposed on the environmental licence, is void.

(2)  If the Director notifies a person under subsection (1)(b) that a condition or restriction of an existing authorisation is void, the condition or restriction is void.

(3)  Nothing in subsection (2) is to be taken to have the effect that a condition or restriction of an existing authorisation is not void only because the person has not been notified under subsection (1) that the condition or restriction is void.
