The responsibilities in the area of immission control are regulated in the Immission Control Competence Ordinance of the state of Baden-Württemberg (ImSchZuVO).

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 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
