Variation of authorisations
4.—(1) Subject to paragraph (2), where a person holds an authorisation in respect of any high-activity source and either—
(a)intends to dispose of or accumulate a high-activity source (other than an existing high-activity source) on or after 1st January 2006; or
(b)intends to dispose of or accumulate an existing high-activity source on or after 1st January 2008;
that person shall apply to the appropriate Agency or the chief inspector under section 17 of the 1993 Act to vary his authorisation to enable the appropriate Agency or the chief inspector to ensure that the authorisation complies with the relevant provisions of the HASS Directive and that person shall make that application in accordance with paragraph (3).
(2) The appropriate Agency or the chief inspector may notify a person to whom paragraph (1) applies—
(a)that such person is not required to make an application under paragraph (1); or
(b)if it, or he, is satisfied that in its, or his, opinion exceptional circumstances apply to that person, that such person may make an application within a period shorter than that provided for under paragraph (3).
(3) Except where notification is given under subparagraph (2)(b), the application under paragraph (1) shall be made—
(a)at least four months before the date the source is intended to be disposed of or accumulated; or
(b)in the case of a high-activity source (other than an existing high-activity source) which is intended to be disposed of or accumulated within four months of these Regulations coming into force, as soon as practicable and in any event at least two months before the date of intended disposal or accumulation of the source.
(4) If a person fails to make an application in accordance with paragraph (3), his authorisation shall be revoked by the appropriate Agency or the chief inspector, so far as it relates to the high-activity source in question.
