We carried out an environmental audit on the territory of a specialized facility of all sources of environmental pollution and, accordingly, we measured the concentration of polluting components embodied in the atmospheric background. As a result of the inventory of emission sources, we recorded the following picture for the total emissions of pollutants into the air zone of the facility: 1.647832 t/year, including 1.597435 t/year in the liquid and gaseous state, and 0.050397 t/year in the solid state. We present the calculation of pollution from generators of emissions of the air zone of the facility, which is recorded on the basis of the Unified Atmospheric Pollution Calculation Program (UAPCP) “Ecolog” (version 3.0). According to the feasibility study, the dispersion calculation was recognized as socially effective for site 2 (hangar) - for NO 2 , NO, kerosene, CO, SO 2 , and abrasive dust. We calculated the surface concentrations of harmful substances in the atmosphere and constructed dispersion maps for the object for the winter period. The implemented research showed that the accumulation of contaminants does not reach the standard values of concentrations at key points suitable for determination at the boundary of the sanitary protection zone and the residential area. The dispersion calculation indicators showed that the predominant fraction of all diffusing contaminants for the hangar in the sanitary protection zone is NO 2 0.82 parts of the maximum permissible concentration with and without background 0.697, and in the residential area, 0.11 parts of MPC without background.
