The regulations concerning responsibility for soil pollution vary between the Flemish, Walloon and Brussels Capital regions.

Flemish region

According to the decree on soil remediation in the Flemish region, the following individuals are liable for carrying out clean-up operations:

  1. Anyone carrying out an activity on the polluted soil for which an environmental permit or an environmental notification is required
  2. If no one carries out such an activity, or if the person carrying out such an activity is exempt from soil remediation (see below), the person who uses the polluted land
  3. If no one carries out such an activity and if no one uses the polluted land (or they are exempt from soil remediation (see below)), the owner of the polluted land.

The people listed above under (a) and (b) will not be held liable, however, if they can each prove that they did not cause the soil pollution and that the pollution dates from before the time they started their activities or started using the polluted land.

The owner of the polluted land will not be held liable if he can prove that he did not cause the soil pollution, that the pollution dates from before he became its owner, that, at the time he became owner, he did not know of any pollution and that no activity mentioned in the list of hazardous activities has been carried out on the land since 1 January 1993. (This last condition does not apply if the soil pollution is 'historical', ie dates from before 29 October 1995). In this case the Flemish public waste agency (OVAM) will carry out soil remediation.

In the Flemish region, a distinction is made between the person liable for carrying out soil remediation and the person responsible for paying any associated costs. In some cases the person liable for carrying out soil remediation may be able to reclaim the costs from the person responsible for the pollution.

Walloon region

In the Walloon region, the Soil Decree of 1 March 2018 provides for the following two hypothesis:

  1. the seller is not designated by the public authorities as holder of soil remediation obligations; in this context parties are free to organise their liability in case of discovery of pollution; and
  2. the seller is designated by the public authorities as holder of soil remediation obligations; in this context parties must agree whether the seller remains liable for said obligations or whether said obligations are transferred to the purchaser in which case a notification to the competent public authorities is compulsory.

The Soil Decree of 1 March 2018 also lists some events (in the context of the filing of a building permit, a single permit or an integrated permit for some acts; in case of termination of some environmental activities; in case of soil damage; upon decision of the administration in case of serious indications of soil pollution), triggering compliance with the execution of soil obligations, including the execution of an exploratory soil study and, if necessary, the conducting of a descriptive soil study and further remediation or other measures.

Brussels Capital region

In the Brussels Capital region, the Soil Clean-Up Act of 13 May 2004 imposes the liability for soil remediation on the person who carried out the risk assessment with a view to transferring the real estate or the environmental permit. However, where the pollution has been fully assessed and can be treated accordingly, that person is only held liable for soil remediation in respect of any pollution they have caused themselves.

If those liable for soil remediation have not accepted their responsibilities, the buyer and the Brussels Environmental Agency (IBGE/BIM) can dissolve the transaction.

The owner or user of a building may also be required to comply with other legal regulations, such as health and safety regulations.

The new Soil Clean-Up Act of 5 March 2009, which came into force on 1 January 2010, as updated by the decree dated 23 June 2017 which came into force on 23 July 2017, maintains the liability system described above.
