The mercury electrolysis plant in Usolye Sibirskoye, which was decommissioned in 1998, is a source of mercury pollution, since measures to prevent mercury pollution of the environment were not implemented after its closure. On the territory of the plant, mercury remained in building structures, in sludge, in soils, in loose sediments. All of them are deposited sources of metallic mercury, from where it continues to spread in the air, soils and groundwater. In order to choose the best method to eliminate the source of mercury pollution, it is necessary to conduct an assessment of the impact on all elements of the environment and to identify the places with the highest mercury contamination. In addition, to propose environmental protection measures those are aimed at eliminating the main sources of metallic mercury release to the environment from the decommissioned mercury electrolysis plant. During the environmental impact assessment of the investigated object, the following tasks were performed: an assessment of the existing environmental situation and the state of the natural environment was carried out; alternative scenarios for achieving the planned activity were considered, with a justification for choosing the best one.
