Overview
The operation of installations that are particularly likely to cause harmful effects on the environment or otherwise endanger, significantly disadvantage or disturb the general public or the neighborhood requires a permit in accordance with the Federal Immission ControlAct (BImSchG). The installations that require a permit are listed in the 4th Ordinance to the BImSchG (4th BImSchV).
The licensing authority must be notified in writing of any changes to the location, nature or operation of an installation requiring a permit at least one month before the changes begin. The authority must then check whether the change requires a permit.
