Questione giuridica chiave
Whether the cantonal sludge disposal plan violated federal environmental law by assigning the appellant's sludge to existing facilities instead of allowing on-site drying and delivery to cement works.
Decisione estratta
No. The canton may use existing, suitable disposal capacity and is not required to choose the most environmentally or economically favorable solution for the operator.
Motivazione estratta
Under USG and GSchV the canton must plan and ensure environmentally sound, economic disposal while avoiding overcapacity. The selected facilities were not shown to be unsuitable, and the appellant had no entitlement to its preferred solution.
