Article 21.

1.

For historical soil contamination, soil remediation is targeted at preventing the soil quality from causing a risk or resulting in adverse effects on people or the environment by using the best available technologies that are not paired with excessively high costs.

In cases where the land in the context of a provisionally established draft land use plan, land-use implementation plan, or project decision is given a different use, then the soil remediation is targeted at preventing the soil quality from causing a risk or resulting in adverse effects on people or the environment within the context of this future use.

2.

If, due to the properties of the soil contamination or of the contaminated land, it is not possible to achieve the target values for soil quality by using the best available technologies that are not paired with excessively high costs, then the soil remediation shall at least be targeted at achieving soil quality which is better than that specified in the applicable soil remediation standards.

In cases where the land in the context of a provisionally established draft land use plan, land-use implementation plan, or project decision is given a use for which stricter soil remediation standards apply, then the stricter soil remediation standards shall be used as the remediation objective.

3.

The provisions of article 10, 6, are accordingly applicable.
