Article 16 Contributions from natural sources

1.   Member States may, for a given year, identify:

2.   Member States shall provide the Commission with lists of any such zones and average exposure territorial units, as referred to in paragraph 1, together with information on concentrations and sources and the evidence demonstrating that the exceedances are attributable to natural sources.

3.   Where the Commission has been informed of an exceedance attributable to natural sources in accordance with paragraph 2, that exceedance shall not be considered as an exceedance for the purposes of this Directive.

4.   By 31 December 2026, the Commission shall provide, by means of implementing acts, technical details on the demonstration and subtraction of exceedances attributable to natural sources. Such technical details shall specify the content of the evidence to be provided by Member States pursuant to paragraph 2.

Those implementing acts shall be adopted in accordance with the examination procedure referred to in Article 26(2).
