(1) If, in the opinion of a regional planning council, any provision of the regional plan may be rendered incapable of implementation—
(a) because any particular person or authority will not be able to meet any costs involved in implementing that provision which in accordance with the regional plan should have been met by that person or authority; or
(b) for any other reason;
it shall report to the Minister who, after making such investigations, including, if appropriate, the holding of a local inquiry, as he considers necessary, may take such action as he deems fit to ensure the implementation of the provision of the regional plan or direct the regional planning council in terms of paragraph (b) of subsection (1) of section eight to alter the provision concerned.
(2) Where a provision in a regional plan conflicts or is inconsistent with a provisioning a master plan, local plan or approved scheme which was operative immediately before the regional plan became operative, the provision of the master plan, local plan or approved scheme shall, in so far as—
(a) that provision has not been implemented; or
(b) there is no valid permit or approval in terms of the repealed Act which authorizes the implementation of that provision; cease to be of effect as soon as the regional plan becomes operative.
