art_18__para_1

1. Where, in a given zone, conformity with the limit values for particulate matter (PM10 and PM2,5), nitrogen dioxide, benzene or benzo(a)pyrene cannot be achieved by the deadline specified in Section 1, Table 1, of Annex I, Member States may postpone that deadline for that particular zone by a period justified by an air quality roadmap and provided that the conditions set out in paragraph 2 of this Article are met: up to 1 January 2040, if justified by site-specific dispersion characteristics, orographic boundary conditions, adverse climatic conditions, transboundary contributions, or where the necessary reductions can only be achieved by replacing a considerable fraction of the existing domestic heating systems that are the source of pollution causing exceedances; or up to 1 January 2035, if justified by projections that demonstrate that even taking into account the expected impact of effective air pollution measures identified in the air quality roadmap, the limit values cannot be attained by the attainment deadline. Where an attainment deadline has been postponed in accordance with the first subparagraph, point (b), of this paragraph, but attainment cannot be achieved by that postponed deadline, Member States may postpone the deadline for that particular zone for a second and last time by a period which is no longer than 2 years from the end of the first postponement period and which is justified by an updated air quality roadmap, provided that the conditions set out in paragraph 2 are met.
