If you wish to make a change to an installation, you must notify the competent authority if a permit for the changes has not already been applied for.

If you wish to make a change to the location, nature or operation of an installation that requires a permit, you must notify the competent authority before starting the change.

The competent authority will confirm your notification and decide whether your project requires a permit and/or which documents you may need to submit. This also applies to accident-relevant changes or if you intend to cease operations.

The notification procedure requires a written or electronic notification. The following documents must be enclosed:

• Required drawings, plans, expert opinions
• explanations and
• other documents (if necessary, ask the competent authority).

• You must enclose the necessary documents with the notification, insofar as these may be required to check whether the project requires approval.
• If, in the opinion of the competent authority, approval is required, an approval procedure must be carried out in accordance with Section 10 BImSchG.
• Approval is not required if the adverse effects caused by the change are obviously minor.

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 submission 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.

At least one month before the change is implemented.

Notification is only required if the change may have an impact on the protected goods listed in Section 1 of the Federal Immission Control Act.

In some federal states, the ELiA application is available free of charge for submitting applications.
