in combustion plants which fall within the scope of Directive 2001/80/EC, which are considered existing in accordance with the definition given in Article 2(10) thereof, where the sulphur dioxide emissions from these combustion plants are equal to or less than 1 700 mg/Nm3 at an oxygen content in the flue gas of 3 % by volume on a dry basis, and where, from 1 January 2008, the emissions of sulphur dioxide from combustion plants subject to Article 4(3)(a) of Directive 2001/80/EC are equal to or less than those resulting from compliance with the emission limit values for new plants ...[+++] contained in Part A of Annex IV to that Directive and where appropriate applying Articles 5, 7 and 8 thereof;

in other combustion plants which do not fall under (a) or (b), where the sulphur dioxide emissions from those combustion plants do not exceed 1 700 mg/Nm3 at an oxygen content in the flue gas of 3 % by volume on a dry basis;

in combustion plants which fall within the scope of Directive 2001/80/EC, which are considered existing in accordance with the definition given in Article 2(10) thereof, where the sulphur dioxide emissions from these combustion plants are equal to or less than 1700 mg/Nm³ at an oxygen content in the flue gas of 3% by volume on a dry basis, and where, from 1 January 2008, the emissions of sulphur dioxide from combustion plants subject to Article 4(3)(a) of Directive 2001/80/EC are equal to or less than those resulting from compliance with the emission limit values for new plants ...[+++] contained in Part A of Annex IV to that Directive and where appropriate applying Articles 5, 7 and 8 thereof;
