Environment Protection (Sea Dumping) Act 1984

The Minister may, when granting a permit or at any time while a permit is in force, impose conditions in respect of the permit and may, at any time, revoke, suspend or vary, or cancel a suspension of, a condition so imposed.

A condition imposed in respect of a permit, or a revocation, suspension, variation or cancellation of suspension of such a condition, takes effect when notice of the condition or of the revocation, suspension, variation or cancellation is served on the holder of the permit or on such later date (if any) as is specified in the notice.
