4.—(1) Subject to paragraphs (2), (5) and (6), and except where a contrary intention appears, these Regulations apply to all mines.
(2) Subject to regulation 69 (plans of abandoned mines), these Regulations do not apply to abandoned mines.
(3) These Regulations apply to a tip if—
(a)the tip is on premises which are deemed to form part of a mine under regulation 3; or
(b)the tip is not on such premises but the mine with which it is associated has not been abandoned and the premises on which the tip is situated continue to be occupied exclusively by the owner of that mine.
(4) If a tip is not, apart from this regulation, deemed to form part of a mine under regulation 3 by reason only that part, but not the whole, of the premises on which the tip is situated is occupied exclusively by the owner of the mine, the tip is deemed to be one to which these Regulations apply and the premises on which it is situated are deemed to form part of the mine with which it is associated.
(5) The Executive may by direction in writing given to the mine operator and owner direct that, as from such day as may be specified in the direction, a tip or part of a tip is, for the purposes of paragraph (4), one to which these Regulations no longer apply.
(6) If the whole or any part of a tip which, apart from this paragraph, would be a tip to which these Regulations apply is appropriated to some use which, in the opinion of the Executive, is inconsistent with the resumption of tipping operations on the tip, or on a particular part of it, the Executive may direct in writing that, as from the day specified in the direction, the whole or part or any part of the tip that is specified in the direction ceases to be a tip to which these Regulations apply.
(7) Where a direction is made under paragraph (5) or (6), the premises on which the tip (or part of the tip) is situated cease to be part of the mine with which the tip is associated.
(8) Part 8 of these Regulations applies to a tip on premises which are occupied exclusively by the owner of an abandoned mine and which are used for depositing refuse from another mine as if the person who is in control of the tip were the mine operator.
