The article provides the general provisions and features of the application of the zonal-indicative methodology for assessing the impact on the state of the atmospheric air of enterprises from local industrial complexes and its practical approbation. A unified approach to determining the zones of negative influence of industrial objects and their groups on the state of atmospheric air is proposed. Analytical dependencies have been established to determine the physical and linear dimensions of the influence zones. The peculiarities of the method of determining "marker" substances for the conditions of formation of the level of atmospheric pollution due to the activity of local industrial complexes are characterized. An algorithm for implementing the method is proposed, which includes procedures for selecting marker substances of the first order (impact), second order (basic), and third order (specific). Significant parameters for the selection procedure of marker substances and the conditions for differentiating emission sources are substantiated, which allows to ensure the effectiveness of the practical implementation of the method. Approbation of the proposed zonal-indicative methodology was carried out on the example of the Kryukiv Carriage Plant, which is part of the local industrial hub in the southern part of Kremenchuk. The calculation of zones of probable influence and other parameters necessary for the application of the indicative evaluation method was carried out. The inverse problem "technological process – marker substance" has been solved. Measurement points of the maximum one-time surface concentrations of pollutants have been determined. Analytical processing of the results of calculation studies and laboratory (including field) observations was carried out. The obtained calculated values of surface concentrations made it possible to determine the substantiated maximum possible contribution of the object to the formation of the general level of atmospheric air pollution in the southern microdistricts of Kremenchuk. In particular, it was established that the level of acceptability of the possible negative impact should be determined based on the results of calculations of the dispersion of marker pollutants in atmospheric air without taking into account background concentrations.
