Article 1
1. The State aid which the United Kingdom is planning to implement for UPM Kymmene-Shotton, amounting to GBP 23 million, is compatible with the common market, up to a maximum amount of GBP 17155000. If during the first five years of operation of the new combustor the gate fee for pre-treated household waste is higher than GBP [...] per tonne on average, so that the eligible costs of the actual combustor are lower than those taken into account in this decision, the United Kingdom shall reduce the aid amount in such a way that the aid level does not surpass 35 % of eligible costs as calculated on the basis of a comparison between the investment in the new combustor and the continued use of the existing combustor, using the actual gate fee for the calculation of the benefits derived from this investment over five years. Any aid paid in excess of the reduced aid amount shall be recovered with interest. 2. The remainder of the aid referred to in the first paragraph of paragraph 1, amounting to GBP 5845000 is incompatible with the common market. That part of the aid may accordingly not be implemented.
