The neighbor burns everything he can get his hands on - plastics, all kinds of rubber, etc. Heavy black smoke comes out of its chimney and it smells strongly. How should we proceed?
If your neighbor uses a combustion source for business activities, you can contact either the relevant municipal (city) office or the relevant territorial inspectorate of the Czech Environmental Inspectorate.
However, if he is a non-business natural person (heating a family house or apartment), then only the municipal office of the municipality with extended powers is responsible for checking and discussing the offence. In such a case, however, the operator of the combustion source is not obliged to allow inspectors access to the source, and the municipal office can only check the darkness of the smoke "from the street" using the Ringelmann scale.
