Applying for approval for accident-relevant changes to an installation requiring approval
Do you intend to make changes to an installation requiring a permit that are relevant to an incident? Then you must first apply for a permit from the responsible authority.
-
Basic information
Do you operate an installation that is subject to immission control licensing and constitutes an operating area or is part of an operating area, and are you planning to make changes to the installation that are relevant to incidents?
These projects can lead to a significant increase in risk being triggered by the plant as a result of the change or other requirements under immission control law can no longer be guaranteed.
Against this background, the immission control authority must review these changes.
To do this, you must submit an application for a modification permit and submit all the documents required for the assessment. The application can be made in writing or electronically.
However, approval is not required if and insofar as the obligation to maintain the appropriate safety distance is already guaranteed at the level of a spatially significant plan or measure by binding specifications.
Requirements
The modification permit will be granted if:
- it is ensured that the obligations arising from the provisions of the Federal Immission Control Act and the Federal Immission Control Ordinances are fulfilled,
- other public law regulations and occupational health and safety concerns do not conflict with the construction and operation of the plant and
- the change is not already covered by Section 16 (1) sentence 1 BImSchG.
-
Procedure
- You apply for the modification permit in writing to the competent authority.
- You enclose the necessary documents with the application.
- The competent authority confirms receipt of the documents and informs you which additional documents it needs to assess the requirements.
- The authority involves the public authorities and the public
- You can only start work on your project once you have received approval.
