Article 15.3.8. When evaluating the various remediation options, primary remediation measures can be chosen which do not entirely return the damaged water and protected species and natural habitats to their reference condition or return them to their reference condition in a shorter period of time. Such a decision can only be made if the natural resources or ecosystem functions under consideration are compensated by strengthening the complementary and compensatory measures, thereby creating a level of natural resources or ecosystem functions similar to that which originally existed.
