art_19__para_2

2. Where in territorial units covering at least one zone, the levels of pollutants in ambient air exceed any ozone target value, laid down in Section 2 of Annex I, Member States shall establish air quality plans for those territorial units that set out appropriate measures in order to achieve the ozone target value and to keep the exceedance period as short as possible. Those air quality plans shall be established as soon as possible and no later than 2 years after the calendar year during which the exceedance of the ozone target value was recorded. Where in a given territorial unit an exceedance of an ozone target value is already covered by an air quality roadmap, Member States shall ensure that the measures set out in that roadmap are appropriate to keep the exceedance period as short as possible and, where relevant, follow the procedure for updating an air quality roadmap as set out in paragraph 5. However, Member States may refrain from establishing such air quality plans or air quality roadmaps to address the exceedance of ozone where there is no significant potential to reduce ozone concentrations, considering geographical and meteorological conditions, and where the measures would entail disproportionate costs. Where an air quality plan or air quality roadmap is not established, Member States shall provide to the public and the Commission a detailed justification as to why there is no significant potential to reduce the exceedance resulting in a decision not to establish an air quality plan or air quality roadmap. At least every 5 years, Member States shall reassess the potential to reduce ozone concentrations. For territorial units where the ozone target value is exceeded, Member States shall ensure that the relevant national air pollution control programme prepared pursuant to Article 6 of Directive (EU) 2016/2284 includes measures addressing ozone precursors covered by that Directive.
