7.—(1) If, on receipt of a notification from any person that he proposes to carry out development within Class B of Part 22 or Class B of Part 23 of Schedule 2, a mineral planning authority are satisfied as mentioned in paragraph (2) below, they may, within a period of 21 days beginning with the receipt of the notification, direct that the permission granted by article 3 of this Order shall not apply to the development, or to such part of the development as is specified in the direction.
(2) The mineral planning authority may make a direction under this article if they are satisfied that it is expedient that the development, or any part of it, should not be carried out unless permission for it is granted on an application because—
(a)the land on which the development is to be carried out is within—
(i)a National Park,
(ii)an area of outstanding natural beauty,
(iii)a site of archaeological interest, and the operation to be carried out is not one described in the Schedule to the Areas of Archaeological Importance (Notification of Operations) (Exemption) Order 1984(1)(exempt operations),
(iv)a site of special scientific interest, or
(v)the Broads;
(b)the development, either taken by itself or taken in conjunction with other development which is already being carried out in the area or in respect of which notification has been given in pursuance of the provisions of Class B of Part 22 or Class B of Part 23, would cause serious detriment to the amenity of the area in which it is to be carried out or would adversely affect the setting of a building shown as Grade I in the list of buildings of special architectural or historic interest compiled by the Secretary of State under section 1 of the Planning (Listed Buildings and Conservation Areas) Act 1990(2)(listing of buildings of special architectural or historic interest);
(c)the development would constitute a serious nuisance to the inhabitants of a nearby residential building, hospital or school; or
(d)the development would endanger aircraft using a nearby aerodrome.
(3) A direction made under this article shall contain a statement as to the day on which (if it is not disallowed under paragraph (5) below) it will come into force, which shall be 29 days from the date on which notice of it is sent to the Secretary of State in accordance with paragraph (4) below.
(4) As soon as is reasonably practicable a copy of a direction under this article shall be sent by the mineral planning authority to the Secretary of State and to the person who gave notice of the proposal to carry out development.
(5) The Secretary of State may, at any time within a period of 28 days beginning with the date on which the direction is made, disallow the direction; and immediately upon receipt of notice in writing from the Secretary of State that he has disallowed the direction, the mineral planning authority shall give notice in writing to the person who gave notice of the proposal that he is authorised to proceed with the development.
