The aboveground extraction of non-energetic, ground-own rust material in the context of dry excavations is determined in Bavaria and North Rhine-Westphalia at the state level by the existing excavation laws (AbgrG). For the excavation of solid rock (limestone, basalt, etc.) in quarries that are not blasted, the AbgrG applies to mining sites with an area of ​​up to 10 hectares. In the event that this size is exceeded or after the mining activities have ended The BImSchV and WHG apply. In the other federal states, this type of raw material extraction is regulated in the respective state building regulations or state nature conservation laws.
