Procedure descriptions
Notify the authorities of the construction, any significant alteration or measures changing the risk classification of installations handling substances hazardous to water (excluding heating oil consumption and JGS installations)
If you wish to construct a new facility for handling substances that pose a risk to water, or to make significant alterations to an existing facility, or to take measures that result in a change to the risk level, you must notify the relevant authority.
You must submit your notification regarding the construction, substantial modification or change to the hazard level of a facility subject to inspection to the competent authority at least six weeks in advance.
A notification is not required if
- an application for a suitability assessment under the Water Resources Act has been submitted for the facility, or
- the installations are subject to an authorisation procedure under other legislation, provided that compliance with the requirements of this Regulation is also ensured as part of that authorisation procedure. This is generally the case for authorisations granted under the Baden-Württemberg State Building Regulations or the Federal Immission Control Act.
