Show modification of an installation requiring approval

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.


  • 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 in accordance with § 10 BImSchG must be carried out.
  • Approval is not required if the adverse effects caused by the change are obviously minor.

What documents do I need?

  • 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).
