Companies require an environmental permit if they wish to use or store hazardous substances. The Dutch Environmental Management Act [Wet milieubeheer] stipulates the conditions that a company must meet in order to obtain a permit. The municipal or the provincial authorities issue this permit, depending on the 'severity' of the company. Once a permit has been issued, the municipality of the province checks whether the company is complying with the permit conditions.
Sections of the Wet milieubeheer that are relevant for the risk map are presented below:
Section 12: Registration data relating to the public safety of establishments, transport routes and pipelines
Section 19: Access to environmental information
