8.—(1) Subject to section 28(1) of the 1990 Act, Part I of the 1990 Act shall have effect in relation to prescribed processes involving the disposal or recovery of waste with such modifications as are needed to allow an enforcing authority to exercise its functions under that Part for the purpose of achieving the relevant objectives.
(2) Nothing in sub-paragraph (1) above requires an enforcing authority granting an authorisation in relation to such a process to take account of the relevant objectives insofar as they relate to the prevention of detriment to the amenities of the locality in which the process is (or is to be) carried on if planning permission, resulting from the taking of a specified action by a planning authority after 30th April 1994, is or, before the process is carried on, will be in force.
