Changes to the location, type or operation of an installation requiring a permit must be notified to the competent authority in writing or electronically at least one month before the change is to begin, unless a permit is applied for.

• You must notify the competent authority of the planned change in writing or, if necessary, using the ELiA web application.
• You enclose the necessary documents with the notification, insofar as these may be required to check whether the project requires approval.
• The competent authority will immediately confirm receipt of the notification and the enclosed documents in writing or electronically; in the case of an electronic notification, it may also request additional copies and the transmission of the documents to be enclosed with the notification in written form.
• Upon receipt of the notification, the competent authority will inform you immediately which additional documents it requires to assess the requirements.
• If necessary, the competent authority will decide that your project requires a permit. The authority will inform you of its decision within one month
• You may implement the change as soon as the competent authority informs you that the change does not require approval or the competent authority has not issued a statement one month after the notification documents are complete.
• In the case of an incident-relevant change, you may only make the change if the competent authority informs you that no approval is required.
