COM(2025) 986 final
ANNEX
to the
DIRECTIVE OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL
amending Directives 2008/98/EC, 2010/75/EU, (EU) 2015/2193 and (EU) 2024/1785 of the European Parliament and of the Council as regards simplification of some requirements and reduction of administrative burden
Annex II
1.Annex II to Directive (EU) 2015/2193 is amended as follows:
(a)In Part 1, tables 1, 2 and 3 as regards the emission limit values for emission of NOx when gaseous fuels other than natural gas are used, the following footnote is inserted after the figures mentioned in the seventh column regarding that pollutant:
‘(*) The emission limit value is not applicable to combustion plants firing gas with more than 20 % (by volume) of hydrogen. Member States shall ensure that the overall load of NOx eventually released into the air over one year is not increased compared to the situation where the emissions from the installation concerned remained compliant with emission limit values set out in Part 1 of Annex II for NOx for the combustion of natural gas, without prejudice to stricter measures required pursuant to Article 6 (9).’;
(b)In Part 2, tables 1 and 2, as regards the emission limit values for emission of NOx when gaseous fuels other than natural gas are used, the following footnote is inserted after the figures mentioned in the sixth column regarding that pollutant:
‘(*) The emission limit value is not applicable to combustion plants firing gas with more than 20 % (by volume) of hydrogen. Member States shall ensure that the overall load of NOx eventually released into the air over one year is not increased compared to the situation where the emissions from the installation concerned remained compliant with emission limit values set out in Part 2 of Annex II for NOx for the combustion of natural gas, without prejudice to stricter measures required pursuant to Article 6 (9).’;
2.Annex III to Directive (EU) 2015/2193 is amended as follows:
(c)In Part 1, point 2, the second indent is replaced by the following two indents:
‘- three times the number of maximum average annual operating hours, applicable pursuant to Article 6(3) or (8), for medium combustion plants with a rated thermal input equal to or greater than 20 MW that meet the requirements applicable to ‘category NRG’ in respect to Stage V controls under Regulation (EU) 2016/1628 of the European Parliament and of the Council 1 ,
- the number of maximum average annual operating hours, applicable pursuant to Article 6(3) or Article 6(8), for medium combustion plants with a rated thermal input greater than 20 MW that do not meet the requirements applicable to ‘category NRG’ in respect to Stage V controls under Regulation (EU) 2016/1628.’
(d)In PART 2, the following points 4, 5 and 6 are added:
‘4. The results of the measurements shall be standardised at the standardised O2 content mentioned in Annex II by applying the following formula:
5. When fuel combustion takes places in an oxygen-enriched atmosphere, the results of the measurements can be standardised at an oxygen content laid down by the competent authority reflecting the special circumstances of the individual case. When the emissions of polluting substances are reduced by waste gas treatment, the standardisation with respect to the oxygen contents provided for in the first subparagraph shall be done only if the oxygen content measured over the same period as for the polluting substance concerned exceeds the relevant standard oxygen content.
6. In the case of complete replacement of ambient air with oxygen, the emission limit values referred to in Article 6 shall be regarded as having been complied with if the emissions are not higher than the emissions from the combustion of the given fuel at the standardised O2 content.’
