Regulatory obligations relating to cadastral parcels: Soil Information Sectors (SIS)

In the light of the information at its disposal, the State shall draw up Soil Information Sectors (SIS). SIS shall include land where knowledge of soil pollution justifies, in particular in the event of a change of use, the carrying out of soil surveys and the implementation of pollution management measures to safeguard safety, health or public health and the environment. They are made available to the public after consulting the town halls and informing the owners.
