Article 20 Changes by operators to installations

Member States shall take the necessary measures to ensure that the operator informs the competent authority of any planned change in the nature or functioning, or any extension, of the installation which may have consequences for the environment, in due time and in any event prior to the implementation of any such change or extension. Where appropriate, the competent authority shall update the permit. Member States shall take the necessary measures to ensure that the competent authority reacts in due time to the information provided by the operator.

Member States shall take the necessary measures to ensure that no substantial change planned by the operator is made without a permit granted in accordance with this Directive.

The application for a permit and the decision by the competent authority shall cover those parts of the installation and those details listed in Article 12 which may be affected by the substantial change.

Any change in the nature or functioning or an extension of an installation shall be deemed to be substantial if the change or extension in itself reaches the capacity thresholds set out in Annex I.
