Article 157.

The OVAM can decide to officially carry out a descriptive soil survey, soil remediation, or the miscellaneous measures, stated in Sections III, VI, and VII of Chapter VI, if the operator, user, and owner of the land on which the soil contamination occurred is not required to carry out a descriptive soil survey or soil remediation pursuant to the provisions of Articles 12 or 23, Articles 105 or 110, or Article 133. If the owner is exempt from the remediation obligation for a part of the soil contamination pursuant to the abovementioned provisions, then the OVAM can decide to officially carry out a descriptive soil survey, soil remediation, or miscellaneous measures, stated in Title III, Chapter VI, Sections III and VI.

If the land, which is the subject of an official soil remediation by the OVAM in the period between the decision up to the official carrying out of the descriptive soil survey, or the soil remediation, and the issuance of the final declaration for the official soil remediation in the context of a provisionally or definitively established land-use implementation plan or special land use plan, is given a use whereby, in application of Article 10, 2 or Article 21, 1, an adapted remediation objective is applicable to the soil remediation, then any additional costs for the official carrying out of the soil remediation due to the application of the adapted remediation objective shall be (pre-) financed by the person who is the owner of the land at the time of the definitively established land-use implementation plan or special land use plan.
