Kernrechtsfrage
How to interpret the contract clause assigning costs for any 'Altlastensanierung' and defining 'Altlast' by federal law.
Extrahierter Entscheid
The clause covers only costs for sanierungsbedürftige belastete Standorte, not all contaminated sites entered in a contaminated-site cadastre.
Extrahierte Begründung
The wording expressly refers to the legal definition of 'Altlast' under federal law. That technical term means a remediation-needed contaminated site under Art. 2(3) AltlV. The reference to an 'Altlastenkataster' did not expand the clause to all cadastre entries.
