Obviously if there is a major advance in technology, that would be one area. If something is wrong in terms of the operation of the licence and there is unsatisfactory application of the licence, that would be another reason. Some other possible reasons include changes in BAT which make it possible to reduce emissions further; questions of operational safety; a review is required due to any Act adopted by an institution of the European Community; and emissions from the activity are deemed to be of such significance that existing emission limit values, parameters or technical measures need to be reviewed. There is plenty of scope and it does happen. I do not want to reduce the time limit because that will clog up the system. A limited number of technical experts are available, so three years is fairer and more manageable.
