Immission control - Applying for a permit for a significant change to a plant requiring authorisation in accordance with the BImSchG
Do you operate an installation subject to immission control authorisation for which you already have an immission control permit and are you planning to make significant changes to this installation?
A permit is required for modifications to an installation that has been approved under immission control legislation if the modification could have a negative impact on the environment and this could be significant for the assessment of the approval requirements for installations requiring approval. A permit is also always required if the modification or expansion of the operation of installations requiring a permit results in the capacity limits or the size of the installation being reached for the first time. In addition, authorisation is always required if the change in itself reaches the relevant performance limit for a permit requirement.
The planned significant change to the installation requiring a licence must be applied for with the responsible licensing authority. As part of the approval procedure, the approval authority will check whether the modified system still fulfils the legal requirements.
However, authorisation is not required if
- the adverse effects caused by the change are obviously minor and
- fulfilment of the requirements of the licensing conditions of the Federal Immission Control Act (BImSchG) for installations requiring a licence is ensured.
This also applies if an authorised installation or parts of an authorised installation are to be replaced within the scope of the authorisation granted.
If the operator is of the opinion that the planned change is not significant, notification of the planned change to the competent authority is required.
Prerequisite
The permit must be granted if it is ensured that the obligations arising from the Federal Immission Control Act (BImSchG) and its ordinances will continue to be fulfilled after the significant change to the plant requiring a permit and that other public law regulations and occupational health and safety concerns do not conflict with the construction and operation of the plant.
Responsible department
The responsibilities in the area of immission control are regulated in the Immission Control Competence Ordinance of the state of Baden-Württemberg.
In most cases, the competent authority for installations requiring authorisation under immission control legislation is the local lower immission control authority, i.e.
- the district office if the premises with the plant are located in a district,
- the city administration if the premises with the installation are located in a city district.
A different responsibility applies in the following cases (e.g. for companies that are subject to the European Industrial Emissions Directive, the Hazardous Incident Ordinance or mining law):
Departments 5, Environment of the respective locally responsible regional councils are the competent immission control authorities for company premises on which
- at least one installation marked with the letter E in column d of Annex 1 of the Ordinance on Installations Requiring a Licence,
- at least one operating area in accordance with Section 3 (5a) of the Federal Immission Control Act (hazardous incident operation),
- at least one installation that requires a licence pursuant to Section 60 (3) sentence 1 no. 2 or no. 3 of the Federal Water Act, or
- at least one landfill in accordance with Article 10 in conjunction with Annex I of Directive 2010/75/EU of the European Parliament and of the Council of 24 November 2010 on industrial emissions (integrated pollution prevention and control), as amended
exists or is to be constructed.
Department 9, State Office for Geology, Raw Materials and Mining of the Freiburg Regional Council is also the state-wide competent immission control authority for
- Operational sites, including the facilities and activities located on them, which are subject to mining supervision,
- Operating sites with cable cars and funicular railways used for passenger transport,
- Sites with high-pressure gas pipelines which, as energy installations within the meaning of the Energy Industry Act, serve to supply gas and which are designed for a maximum permissible operating pressure of more than 16 bar,
- Underground waste disposal facilities and
- Industrial premises with installations used for the construction, significant expansion and significant modification of underground cavities.
Please ensure that you submit your licence application to the immission control authority responsible for your facility.
Procedure
The authorisation procedure requires an application, which must be accompanied by the drawings, explanations and other documents required to check the authorisation requirements. If further documents are required by the competent immission control authority or the relevant specialised authorities for an assessment, these must be submitted subsequently.
Once the application is complete, the licensing authority requests the authorities to be involved in the procedure to submit their comments on the licensing requirements. In the case of a formal authorisation procedure, there is also public participation in which the project is made public and the application documents are displayed for one month and objections can be raised by the public. After the objection period has expired, the licensing authority can discuss the objections raised against the project in good time with the applicant and those who have raised objections. In accordance with Section 16 of the Federal Immission Control Act (BImSchG), the licensing authority should refrain from publicising the project and displaying the application and documents if the project sponsor requests this and there are no concerns of significant adverse effects on relevant protected assets.
Once the licensing authority has determined all the circumstances that are relevant to the granting of a licence, a decision must be made on the application. The authorisation decision must be substantiated in writing and will be sent to you and the persons who have raised objections. The notification of the authorisation notice to objectors can be replaced by a public announcement.
Pursuant to Section 13 BImSchG, the immission control permit includes other official decisions relating to the plant, in particular permits, approvals, concessions, authorisations and licences under public law. Excluded from this are planning approvals, approval of operating plans under mining law, official decisions based on nuclear regulations and water law permits and authorisations.
Deadlines
The operator must obtain prior authorisation from the competent authority for any significant change to the system.
Required documents
The application must be accompanied by the documents required for an assessment. These are, for example
- Descriptions of the project, including information on plant components, process steps, material and product data,
- schematic diagrams and flow charts,
- Information on possible disruptions to normal operation,
- Information on emissions and immissions,
- Information on waste and waste water,
- Construction documents: site plan, construction drawings, construction description,
- Forms of "Annex 1" to the Guidelines for authorisation and notification procedures in accordance with the Federal Immission Control Act of the Baden-Württemberg Ministry of the Environment
The competent authority may request further documents if necessary. Coordinate in advance with the responsible immission control authority regarding the documents required for an assessment.
If official decisions concerning the installation are communicated as part of the authorisation procedure (e.g. building permit), the documents required for this must also be submitted.
Costs
The fees are based on the investment costs for the system.
Processing time
As a rule, the licensing authority must check whether the documents are complete within one month of receiving the application. If the application documents are not sufficient for an assessment, they must be completed by the applicant.
Once the application documents are complete, the statutory deadlines begin for the authorisation procedure under immission control law, which is six months in a formal procedure and three months in a simplified procedure for modification projects. The deadlines can be extended by three months if this is necessary due to the difficulty of the examination or for reasons attributable to the applicant.
Miscellaneous
Coordinate in advance with the responsible immission control authority regarding the documents required for an assessment.
The application for a significant change to an installation requiring authorisation is made as part of the administrative service "Immission control - Applying for the construction and operation of an installation requiring authorisation".
