Permits: review of conditions
44.—(1) SEPA must review the conditions of a permit—

(c)where it is necessary to comply with a new or revised environmental quality standard in accordance with Article 18 of the Industrial Emissions Directive,
(d)within 4 years after the date of publication of BAT conclusions relating to the main activity of an installation if the permit relates to an activity in respect of which those conclusions were published, and
(e)where the permit relates to an activity not covered by any BAT conclusions and a development in best available techniques allows for the significant reduction of emissions at the installation or mobile plant.
