Section 6 Amendment of development plans
At least once in every five years after the date on which a development plan for any area was approved by the Minister, the local planning authority shall carry out a fresh survey of that area, and submit to the Minister a report of the survey, together with proposals for any alterations or additions to the plan which appear to them to be required having regard thereto.
Without prejudice to the provisions of the preceding subsection, any local planning authority may at any time, and shall if so required by directions of the Minister, submit to the Minister proposals for such alterations or additions to the development plan for their area or any part thereof as appear to them to be expedient, or as may be required by those directions, as the case may be.
Subject to the next following subsection, where proposals for alterations or additions to a development plan are submitted to the Minister under this section, the Minister may amend that plan to such extent as he considers expedient having regard to those proposals and to any other material considerations; and any such amendment may in particular provide for securing that any land previously designated by the plan as subject to compulsory acquisition shall cease to be so designated, or that any land not previously so designated shall be so designated.
Subsections (2) to (5) of the last preceding section shall apply in relation to the amendment of a development plan as they apply in relation to the approval of such a plan, with the substitution—
in subsection (2) of that section, for the reference to the date on which the plan is approved, of a reference to the date on which the amendment is effected, and
in subsections (3) and (4) of that section, for the references to the plan as submitted to the Minister, of references to the proposals submitted to him under this section.
Where in accordance with the provisions of subsection (5) of section four of this Act a development plan has been prepared for part of the area of a local planning authority, and has been approved by the Minister, then (without prejudice to the provisions of subsection (2) of this section) the periods of five years mentioned in subsection (1) of this section shall run from the date on which development plans in respect of the whole of the area have been approved by the Minister.
