Article 15e 4.

Where the screening process identifies a project to be highly likely to give rise to significant unforeseen adverse effects as referred to in paragraph 3, the competent authority shall ensure, on the basis of existing data, that appropriate and proportionate mitigation measures are applied to address those effects. Where it is not possible to apply such mitigation measures, the competent authority shall ensure that the operator adopts appropriate compensatory measures to address those effects, which, if other proportionate compensatory measures are not available, may take the form of a monetary compensation for species protection programmes, in order to ensure or improve the conservation status of the species affected.
