On the ground of appropriate technical-economic or hygiene grounding the document enables of increasing the sanitation-protective zone. In spite of the norms regulating the zoning of industrial facilities, in reality, the majority of enterprises have not been separated from dwelling areas. For example, in the beginning of XX century the electric-van-making factory was put into operation, around which no population was found those times. In the process of the development of the city it proved that at the expense of the reduction of the areas adjacent to the factory the dwelling houses became located in the immediate vicinity of the factory. The same situation is at the silicate brick factory of Avtchala, the Centrolit factory.

In recent years the increase in private enterprises of low capacity showed up, frequently, in the places or areas unsuitable for them. Therefore the sanitation and environmental elementary norms are disturbed.

At present the large industrial facilities function on the average just by 10% of the capacity envisaged by the project. At the best, private enterprises of low capacity originate on their territory, which work with partial forcing and are featured by instability.

The environmental permits legislation exists for the designing, construction and operation of new facilities, which requires conduct of the process of environmental impact assessment (EIA) for the facilities with high environmental risk.
